[0285] System 1 according to the invention for distributing goods represented in FIG. 1 includes a micro-tunnel 2 that forms at least one transport loop 7 extending at least partly under a dense urban area M constituting a town center and including, as can be seen in FIG. 2, surface buildings B as well as underground structures I, under which the micro-tunnel 2 extends. The latter is adapted to enable the automated transport of goods present in containers.

[0286] The system 1 includes exchange stations 4 for lowering goods from and raising goods to the surface, these exchange stations 4 being disposed along the transport loop 7 in such a manner as to enable conveying of the goods in different zones Z of the town with a view to their local distribution.

[0287] The system 1 also includes stations 6 for scheduling the goods, which are provided outside the urban area M, at the periphery of the town, so as to facilitate the conveying and the departure of goods by surface transport means 8 such as trucks.

[0288] Each exchange station 4 includes a shaft in which extends a system for transporting containers between the surface or an underground warehouse and the micro-tunnel 2.

[0289] Referring to FIGS. 3 and 4, it can be seen that the containers 3 are carried by transport shuttles 17 that circulate unidirectionally in the micro-tunnel 2.

[0290] The containers 3 loaded with goods are brought by surface transport means 8 to at least one of the scheduling stations 6 situated at the periphery of or outside the town. The containers are then lowered to the micro-tunnel 2. Each container 3 is then transported to the exchange station 4 where at least some of the goods transported have to be delivered, and then raised to the surface. After those goods are removed, the container 3 is lowered again to the micro-tunnel 2 to continue its convey.

[0291] One or more elevators may be provided for raising and lowering the containers.

[0292] The containers are preferably stored in one or more surface warehouses or warehouses buried at a shallow depth.

[0293] In the FIG. 3 example the exchange station 4 connects a first section 107a of the transport loop 7 to a second section 107b that is aligned with the first in this example.

[0294] Cable drive mechanisms 42 are provided to move the shuttles 17 along the various sections 107 of the transport loop.

[0295] The shuttles 17 include a disengageable clamp device that comes to be clamped onto the transport cable in an analogous manner to the mechanisms present on disengageable ski lifts and chair lifts.

[0296] Devices 70 and 80 are respectively provided to produce progressive braking on arrival at the station 4 and progressive acceleration on departure from the station thanks to an auxiliary drive system.

[0297] In the FIG. 3 example the braking device 70 includes for example rollers that apply increasing friction to the shuttles 17 on their arrival in the vicinity of the station 4 so as to slow them down as far as the zone in which driving by the cable ceases. Each shuttle is then taken up by a conveyor means, for example by rollers that drive it past a system 50 for loading/unloading the containers 3.

[0298] This system 50 may include a roller conveyor 51 for transporting the containers 3 in front of the entry of an elevator 60 that enables them to be moved to the surface. The elevator may be a service elevator with two compartments, one used for example to recover the containers 3 offloaded by the shuttle 17 and the other to receive the containers 3 sent down from the surface and load them onto the shuttles 17, as shown.

[0299] The shuttles 17 then leave the station 4, being progressively accelerated by the device 80, which enables the shuttles 17 to reach the speed of the drive cable so as to be driven by the latter.

[0300] In the FIG. 4 variant the micro-tunnel sections 107a and 107b are at an angle to one another and the exchange station 4 includes a loading/unloading system. The shuttles that reach the exchange station 4 are successively positioned on a track section 90 mobile laterally between a first position in which the latter comes into alignment of the rails 40 of the upstream section 7a to receive the shuttles 17 and a second position as shown in FIG. 4 for unloading the shuttle 17 in which this mobile track section 90 comes into alignment with a loading/unloading track 91. That track 91 passes in front of an opening for transferring the containers 3 to an elevator 60 for raising/lowering them.

[0301] Once the containers 3 have been loaded on or unloaded from the shuttles 17 that pass in front of the elevator 60 with the aid of any appropriate transfer mechanism, the shuttles are positioned on a second mobile track section 92 that is movable laterally between a position enabling loading of the shuttles 17 that travel on the track 91 and a position in which that mobile section is aligned with a third track section 95 situated on a turntable 96. That turntable 96 enables recovery of the shuttle 17 previously positioned on the second mobile track section 92 and its rails may be placed in alignment with the track 40 of the downstream second section 107b in order for the shuttle 17 to depart on the latter.

[0302] A system of this kind for loading/unloading the shuttles 17 enables rapid and automated handling of the containers 3, compatible with driving by cables 42, and the presence of the mobile platform 96 facilitates the construction of the loop by enabling the use of rectilinear or substantially rectilinear loop sections 107.

[0303] In variants that are not shown the shuttles 17 are pivoted without a turntable by causing them to roll on castors or rollers and no longer on rails between the sections 107a and 107b, using guide means enabling a relatively tight turn to be executed where necessary.

[0304] In variants that are not shown the shuttles may also be moved to an unloading/loading track without transporting them simultaneously with the rails on which they are engaged, by moving them with the aid of a conveyor.

[0305] In a further variant the shuttles may be unloaded or loaded when they are on a track situated in continuity with tracks extending in the sections 107 of the micro-tunnel.

[0306] The micro-tunnel and the exchange stations are preferably under a reduced oxygen or inert atmosphere in order to reduce the risk of fire. This enables the cost of the infrastructure to be limited by making unnecessary certain safety devices that would otherwise have been imposed by the standards.

[0307] There has been represented in FIG. 5 a variant embodiment of the transport loop 7 including rectilinear or substantially rectilinear micro-tunnel sections 107 connected by the exchange stations 4, which are as shown in FIGS. 3 and 4 for example.

[0308] The main flow of goods injected into the loop 7 is able to circulate via a so-called penetrating line 110 connected to a peripheral scheduling station 6 that constitutes a rear base, where the goods to be transported are packed and scheduled as a function of their destination. Thus the goods intended to pass in transit through the same exchange station 4 of the loop 7 to reach their final destination are packed in the same container 3, advantageously at the scheduling station. The shuttles may be loaded at the scheduling station 6 in an order that is a function of the destination of the goods loaded onto each of these shuttles. Thus the station 6 can handle the management of a major portion of the flow of goods that is injected into the loop and can enable limitation of the flow of goods loaded onto the shuttles from the exchange stations 4 situated on the loop.

[0309] The line 110 may be bidirectional and produced in the form of a tunnel with two tracks or two parallel or non-parallel micro-tunnels.

[0310] At the surface, the exchange stations may include an area for storing the containers 3 pending sending thereof to a loading or unloading dock where they can be installed on electric vehicles for example.

[0311] There has been represented in FIGS. 6 and 7 an example of a container 3 according to one aspect of the invention.

[0312] That container 3 includes a fork-liftable base 200 and lateral walls 201, a rear wall 202 and a top wall 203. It is provided at the front with a closure means that may be of any type and preferably takes the form of a bi-fold door 204, each door including two panels 205 that can be folded one against the other. The panels 205 are articulated to one another and articulated to the lateral walls of the container 3.

[0313] Thus when the door 204 is open it provides totally free access to the interior volume of the container. When the panels 205 are folded against one another, as shown in FIG. 8, the overall size of the doors is reduced and the containers may be disposed close to one another, to minimize their footprint.

[0314] The fork-liftable base 200 has passages 210 for inserting the forks F of a pallet truck passing through it from front to rear and other passages 211 passing through it from left to right.

[0315] The width a.sub.1 of the passages 210 is preferably between 20 and 50 cm inclusive, in particular between 29 and 50 cm inclusive, and that a.sub.2 of the passages 211 between 20 and 25 cm inclusive. The width b.sub.1 of the blocks outside the passages 210 is preferably between 10 and 20 cm inclusive and that b.sub.2 of the central block present between the passages 210 is preferably between 10 and 18 cm inclusive. The passages 211 are preferably at a distance c.sub.1 from the edge of the container between 8 and 15 cm inclusive, and the distance c.sub.2 between the passages 211 is preferably between 10 and 18 cm inclusive. The passages formed on the shorter sides of the base of the container are preferably narrower than those produced on the longer sides, so as to reduce the risk of incorrect centering of the forks used to lift the container.

[0316] The passages 211 may be open at the bottom or not. The same applies to the passages 210. In FIGS. 9 and 10 the passages 210 are closed at the bottom by a wall 214 while the passages 211 are open at the bottom.

[0317] The base 200 may be made of metal or a synthetic, in particular thermoplastic, material, possibly a composite or fiber-reinforced thermoplastic material. The base 200 may include a metal framework onto which a thermoplastic material is overmolded.

[0318] The lateral, rear and top walls of the container may be made of metal or synthetic, in particular composite, material. The container may include a metal frame onto which a thermoplastic material is overmolded to form said walls.

[0319] The container preferably includes lateral, rear and top walls that are made of metal, in particular of corrugated sheet metal for greater stiffness. These walls may be assembled to a metal frame that is preferably strong enough to allow stacking of the containers.

[0320] As shown in FIGS. 11 to 13, the container 3 preferably includes means 220 for centering a pallet inside the container resting on the base 200.

[0321] In the example considered, those centering means include a ramp that extends over the perimeter of the base 200 inside the container and has two openings 222 at the front for the passage of the forks F of the pallet truck, as shown in FIG. 12.

[0322] There has been schematically represented in FIGS. 11 to 13 a pallet P placed on the base 200. It is seen that the clearance j between the base of the ramp and the edge of the pallet is small, for example between 0.5 and 2 cm inclusive.

[0323] The height k of the ramp is for example between 1 and 20 cm inclusive. This height may be less than that of the pallet P.

[0324] The container 3 may be constructed so that it can be compartmentalized, as shown in FIGS. 14 to 16.

[0325] In this example the container 3 is made with ribbed lateral walls 201 onto which profiles 230 are fixed at various heights inside the container, for example at , and the height.

[0326] Each profile 230 preferably has a protrusion 231 that espouses the concavity of a rib and two flanges 232 that bear on the back of the adjacent ribs. The flanges 232 may be fixed by rivets 234 to the lateral wall 201 of the container 3.

[0327] Each profile 230 has a bearing surface 235 for a board 238 for compartmentalizing the container 3, as shown.

[0328] In the variant shown in FIGS. 17 to 20 the container 3 includes retractable supports 240 that can assume a first configuration, shown in FIG. 17, in which they are folded against the adjacent wall 201, and a second, deployed configuration, shown in FIGS. 18 to 20, in which they support the load.

[0329] Each support 240 may, as shown in FIG. 20, include a lug 241 that is articulated to a support 242 fixed to the adjacent wall 201, for example by riveting it thereto.

[0330] The lug 241 may have a shape adapted to bear on a flank of a rib of the metal sheet, as shown in FIG. 20, which distributes the forces over a larger area.

[0331] The lug 241 may be articulated on the support 242 in such a manner as to make it obligatory to raise the lug 241 before being able to tilt it. This guarantees stable retention in the retracted configuration.

[0332] When deployed, the supports 240 may serve to hold a pallet P, as shown in FIG. 18, or to hold boards 238 each defining the floor of a compartment, as shown in FIG. 19.

[0333] The possibility of placing pallets at different heights provides additional flexibility by enabling use of the same single container with a plurality of pallets, which is of interest if the goods conditioned on the pallet are of low height.

[0334] When the supports 240 are retracted, they do not interfere with the goods M carried by the pallet P, as shown in FIG. 17.

[0335] Various examples of containers 3 suitable for transporting fresh or refrigerated goods will now be described with reference to FIGS. 21 to 28.

[0336] In the example from FIGS. 21 and 22 the container 3 receives a fork-liftable thermally insulating material box 250. A front panel 251 made of the same material may be mounted on the box 250, as shown in FIG. 22.

[0337] FIGS. 23 and 24 represent a variant that differs from the example from FIGS. 21 and 22 by the fact that the container 3 has two stacked compartments, each receiving a fork-liftable box 250. Each of these boxes 250 may be closed before the container 3 is closed by a corresponding individual closure panel 251.

[0338] In the variant from FIGS. 25 and 26, the container 3 receives an isothermal box 252 closed at the front by a front panel 253 positioned before closing the container 3.

[0339] The box 252 is not a fork-liftable box but can be replaced if damaged.

[0340] The variant from FIGS. 27 and 28 differs from that from FIGS. 25 and 26 by the fact that the box 252 has multiple compartments 254 each provided with an individual closure panel 255.

[0341] The container 3 preferably has a width W between 125 cm and 135 cm inclusive, a depth D between 85 cm and 130 cm inclusive, and a height H between 180 cm and 240 cm inclusive. A container of this kind is referred to as a single container because it is intended to receive one standard pallet, for example with sides 80 cm by 120 cm.

[0342] In a variant the container is less high and has a height H between 85 and 90 cm inclusive for example, as shown in FIG. 30.

[0343] The container 3 may again be a double container, as shown in FIGS. 31 and 32, and have the same width W but a depth D between 170 and 250 cm inclusive, so as to receive two pallets P disposed side by side, for example two standard EUROPE pallets.

[0344] There has been represented in FIG. 33 a container 3 that incorporates a bag 280 for the bulk return of packaging.

[0345] This bag 280 is for example open at the top and suspended from slides 281 present under the top wall of the container 3.

[0346] The bag 280 may be folded against the rear wall of the container 3 when the latter receives goods on pallets.

[0347] Once those goods have been removed, the bag 280 may be deployed by causing its attachments to slide toward the front, as shown in FIG. 34.

[0348] As shown, the bag 280 may preferably be loaded from the front, thanks to a front panel 282 provided with a zip closure 283 for example.

[0349] Once the packaging E has been removed from the bag 280, the front panel 282 may be closed again and the bag 280 then folded against the rear wall of the container 3.

[0350] Thus the containers 3 can easily transport goods and return empty packaging.

[0351] There has been represented in FIG. 36 a container 3 in which is received a bin 300 suitable for collecting bulk waste.

[0352] The outside dimensions of the bin 300 are adapted to suit the interior volume of the container 3 and there is for example a gap of less than 15 cm from the lateral walls of the container 3, better less than 10 cm, even better less than 7 cm.

[0353] The bin 300 may be fork-liftable thanks to a base 301 including passages 301 for this purpose.

[0354] The bin 300 may include a loading opening at the front, possibly provided with a closure flap 303.

[0355] The container 3 may be left in a collection zone with the bin 300 inside it. When the latter is full, the container may be picked up and lowered by an exchange station 4 to the micro-tunnel, and then sent to a scheduling station 6 where it is unloaded.

[0356] FIG. 37 represents a variant embodiment of the bin 300 which differs from that shown in FIG. 36 by the fact that the bin 300 is provided with wheels 309 that enable it to be moved easily when removed from the container 3.

[0357] The bin 300 may be removed from the container 3. It may as shown in FIG. 37A include a pivoting lid 317 so as to be emptied into a truck thanks to lifting bars 308 that enable it to be upturned above the area of the truck provided for this purpose.

[0358] The container 3 according to the invention is preferably connected, that is to say able to communicate with an external computer system.

[0359] The container 3 may include an electronic circuit 320 adapted to transmit information to a server tasked with tracking the circulation of the containers 3.

[0360] This electronic circuit 320 may be disposed in the base 200.

[0361] The container 3 may include one or more sensors 321 that provide the electronic circuit 320 with information for example on the temperature inside the container 3, the relative humidity, opening of the container 3, its position, its movements.

[0362] This data may be recorded locally and transmitted to the server tasked with tracking either periodically or upon passage in the vicinity of a reader terminal.

[0363] The container 3 may also be adapted where appropriate to read an electronic tag 400 carried by the pallet P disposed inside the container 3.

[0364] That tag 400 may transmit to the container 3 an identifier of the pallet P.

[0365] The container 3 may communicate with the tracking server and receive from the latter information concerning the destination of the pallet for example.

[0366] Once arrived at its destination, the container 3 may advise the tracking server of the arrival of the pallet P.

[0367] Data may be transmitted from the container 3 in various ways, for example via an IoT transmission network such as SIGFOX or LORA.

[0368] The electronic device equipping the container may be programmed to provide various functions, in particular some or all of the following functions:

[0369] tracking the position of the container, by receiving location information from a geolocation chip equipping the container, of GPS type for example, and/or by receiving information from a terminal near which the container passes, for example on arriving at an exchange station,

[0370] recording the path of the container and/or transmitting that path to a server tasked with tracking the containers,

[0371] storing the data from at least one temperature, relative humidity, acceleration, liquid and/or pressure sensor and/or transmitting data to a server tasked with tracking the containers,

[0372] where appropriate signaling when the data measured by a sensor departs from a predefined range, for example excessive temperature or excessive acceleration linked for example to dropping the container when handling it,

[0373] detecting opening of the container and/or signaling that opening to a server tasked with tracking the containers, so as to guarantee the traceability of the goods loaded in the container,

[0374] detecting loading of the container, for example with the aid of an optical sensor or a strain gauge, which can provide information on the weight of the goods and trigger an alarm in the event of overloading, or enable verification on the basis of measurement of the weight the consistency of the measurement with the expected weight, which can assist verifying that given goods have indeed been loaded into the container that is to receive them,

[0375] controlling opening of the container if the door is provided with a remotely controllable lock,

[0376] controlling opening of one or more racks of the container if those racks are provided with remotely controllable doors,

[0377] enabling communication with a cellphone or other appropriate terminal to control the opening of one or more doors, that communication being for example of WIFI, BLUETOOTH, NFC, WAN or LAN type,

[0378] reading at least one RFID chip carried by a pallet or goods present on the pallet or carried by an element fixed in the container, such as for example a locker module, one or more isothermal boxes or a bin,

[0379] exchanging data with RFID chips carried by goods on the pallet to inventory the latter and for example to verify that only the goods to be taken off at the level of an exchange station or a collection point have been,

[0380] storing information on the provenance of the load and/or its destination,

[0381] transmitting this information to a shuttle or to a surface vehicle on which the container is placed and/or to a robotic system tasked with loading and/or unloading the shuttles or to an operator tasked with taking off the goods,

[0382] charging a battery equipping the container,

[0383] controlling the locking means on a shuttle or surface vehicle, in particular unlocking a container when the latter arrives at its destination.

[0384] Examples of use of a container 3 as a locker will now be described with reference to FIGS. 39 to 58.

[0385] In these examples, the container 3 includes at least one closed compartment the opening of which can be triggered by a person authorized to recover the contents of that compartment.

[0386] The container 3 may be warehoused in an area reserved for that purpose. Persons are advised of the arrival of the container with their package inside it and trigger opening of the corresponding compartment for example using a code entered with their cellphone.

[0387] The compartment containing the package may be equipped with indicator lights advising the person of its location, as shown in FIG. 58.

[0388] The distribution system according to the invention preferably includes containers 3 having a common main part, of the same interior volume for all the containers, having the same base, lateral, top and rear walls. On the basis of this main part common to all the containers, it is possible to introduce variations according to the type of goods to be transported or the intended application.

[0389] It is therefore of interest to disposed in the common main part a locker module 500 including a plurality of independent racks closed by as many doors 501, each unlocked electronically by entering a specific code with the aid of a cellphone for example.

[0390] This module 500 may be fixed to the lateral walls 201 of the container 3, as shown in FIG. 39, or to the base 200 of the container 3, as shown in FIG. 40.

[0391] The racks of the module 500 may be different sizes, so as to accommodate a great variety of goods.

[0392] In FIGS. 41 to 53 there have been represented various arrangements of the container 3 when the latter is produced with a plurality of compartments each having a specific opening.

[0393] If necessary a plurality of containers 3 can be stacked, as shown in FIGS. 54 to 57.

[0394] In FIG. 59 there has been represented very schematically a shuttle 17 adapted to circulate in the micro-tunnel and containers 3 in place on the latter.

[0395] The base 200 of the containers 3 is adapted to be locked in position on this shuttle 17.

[0396] To provide this locking the shuttle or the vehicle may be equipped with at least one lock 550 that is engaged onto the base to immobilize it, as shown in FIG. 60.

[0397] This lock 550 may include a hook that hooks onto a relief of the base 200, for example a relief 552 disposed in a passage to receive a pallet truck fork.

[0398] To unlock the container 3 the lock is moved for example thanks to an electromagnetic or pneumatic actuator, as shown in FIG. 61.

[0399] Again the container may be equipped with a lock 560 adapted to hook automatically onto a corresponding relief 561 of the shuttle 17 or of the surface vehicle.

[0400] To unlock the container 3 this lock is moved, for example by an actuator present on the shuttle 17 or the surface vehicle, or forming part of the base 200 of the container 3.

[0401] In the variant from FIGS. 68 to 72, the platform 1000 intended to receive the container, in particular on the shuttle 17, includes a locking mechanism 900 actuated automatically by putting the base of the container 3 in position.

[0402] The base 200 of the container may be provided with an attachment bar 910 as shown.

[0403] The mechanism 900 includes a support element 911 mobile relative to the platform 1000 that is pushed by the base 200 on putting the container into position, as shown in FIGS. 68 to 70.

[0404] This element 911 may include a hook 912 that engages over a corresponding relief 913 produced on the base 200, for example on a profile 913 intended to receive a pallet truck fork, that relief being in the form of a hole 914 in this profile. Engagement of the hook 912 in the hole 914 and the profile 913 abutting against the support element 911 participate in retaining the container 3 on the platform.

[0405] The support element 911 is connected by a linkage 916 to a pivoting hook 920. A rack may be provided on the linkage 916, cooperating with teeth present on the hook 920 to transform the backward movement of the element 911 when fitting the base 200 into position into a rotation of the hook 920. At the end of its rotation the hook 920 is engaged over the bar 910, as shown in FIG. 71, which also contributes to the retention of the container 3 on the platform 1000.

[0406] As shown in FIG. 72, a locking pin 930 mobile vertically relative to the platform and a corresponding housing 931 on the base 200 of the container 3 may be provided to render secure the immobilization of the latter.

[0407] The pin 930 is for example actuated by a pivoting arm 932 which may be moved by any appropriate actuator.

[0408] A return spring 933 is provided to return the hook 920 to the open position when the container 3 is unloaded. To this end, the pin 930 is retracted into the platform 1000 and the container 3 is moved back relative to the support element 911. During this backward movement, the spring 933 causes the support element 911 to follow the container 3 and the hook 920 to release the bar 910.

[0409] A slight clearance may be provided, if necessary, to enable the container 3 to be lifted slightly by the forks of a pallet truck with the hook 920 covering the bar 910 so as to move it back. Alternatively, the platform 1000 is provided with rollers on which the base 200 rests so that retraction of the pin 930 causes automatic backward movement of the container 3 because of the return effect of the spring 933, the container 3 rolling on the rollers during this backward movement.

[0410] In the variant embodiment from FIGS. 73 to 76 the platform 1000 includes rollers 1010 on which the container 3 is able to roll.

[0411] The base 200 of the container is produced with lateral flanges 290 and the platform 1000 is provided with rollers 1030 under which the flanges 290 of the base 290 engage. The platform 1000 may include four rollers 1030 so that the container 3 is therefore retained vertically on the platform 1000 and immobilized in the direction perpendicular to its insertion by abutments 1040 on which the rollers 1030 may be mounted.

[0412] A locking pin mechanism 930 as described hereinabove provides complete immobilization of the base 200.

[0413] To remove the container 3 from the platform 1000 the pin is retracted and the base 200 is moved in the opposite direction relative to the platform 1000.

[0414] An example of loading at least one container 13 onto a surface vehicle 600 will now be described with reference to FIGS. 65A to 65C.

[0415] The containers 3 are for example loaded in groups of four, six or eight onto the same vehicle.

[0416] The containers 3 may be conveyed from the elevator of the exchange station to a vehicle loading dock by any type of conveyor, for example by roller conveyors.

[0417] The latter may be situated at the same height as the loading platform of the vehicle, as shown.

[0418] The latter may be a low-loader autonomous vehicle such that its total height T, as shown in FIG. 66, is less than 2 m80, to enable it to circulate in underground carparks. The platform 1000 intended to receive the containers may be situated at a height M above the ground less than or equal to 40 cm.

[0419] The vehicle may be provided at the rear with a retractable curtain 606 lowered during loading of the containers 3 and raised during transportation thereof.

[0420] The containers 3 are preferably unloaded at their destination using an unloading dock at the same height as the platform of the vehicle. The container 3 may also be provided with lifting lugs, in which lifting hooks can be engaged.

[0421] When the container 3 is produced in the form of a locker, the container 3 may remain on the vehicle; in this case, the intended recipient of the package is advised of the arrival of their package by a message on their telephone, for example, and can go to find it at a parking place of the vehicle.

[0422] The container 3 according to the invention being fork-liftable, it may be moved using a pallet truck.

[0423] In the absence of a pallet truck the container 3 may be placed on a trolley 700 as shown in FIG. 67, including wheels 701 and a tray 702 matching the dimensions of the base 200, with a rim 703 at the periphery to hold the container 3 centered on the tray 702.

[0424] There has been shown in FIG. 77 an example of a shuttle 17 in a micro-tunnel 2 of which only a portion of its wall 2002 is represented.

[0425] The example of a shuttle 17 represented includes a chassis 11000 including two longitudinal members 11001 and 11002 and a plurality of crossmembers that extend transversely to the longitudinal members 11001 and 11002, in particular a front crossmember 11003 and an adjacent crossmember 11005, a rear crossmember 11004 and an adjacent crossmember 11006 and at least one intermediate crossmember 11007, the longitudinal members 11001 and 11002 and the front crossmember 11003 and the rear crossmember 11004 forming a rectangular peripheral frame.

[0426] In the example considered, the chassis 11000 is sized to receive four containers 3 disposed in two rows of two containers 3.

[0427] As shown in FIG. 77 the shuttle 17 includes two spaces 2012 to receive one or more containers 3.

[0428] The shuttle 17 is open at the sides and includes a front barrier 2003 and a rear barrier 2004 as well as an intermediate barrier 2005, all fixed to the chassis 11000, the intermediate barrier 2005 providing the partition between the two spaces 2012.

[0429] The front barrier 2003 and the rear barrier 2004 are retained by a support structure 2040 with legs 2030 that rest on the peripheral frame of the chassis 11000.

[0430] Each barrier may include a bottom guide slide 2050 and a top guide slide 2060, the top slide 2060 being situated substantially at the level of the upper half of the containers 3 when the latter are in place in the receiving space 2012.

[0431] The space between the slides of two adjacent barriers may be slightly greater than the length of a container 3 so as to enable it to slide between them when loading or unloading the shuttle.

[0432] The guide slides may be slightly inclined at their ends so as to define insertion ramps 20170 facilitating engagement of the containers in the receiving space 2012.

[0433] In the example considered, each space 2012 is able to receive two containers 3 disposed side by side, only one of which is represented. Each space 2012 includes, in particular over all of its surface, transport rollers 2008 on which the fork-liftable base 200 of the container 3 rests. These transport rollers 2008 enable each container 3 to be rolled, in particular when it is placed in and/or removed from the shuttle 17. The transport rollers 2008 are oriented in the longitudinal direction of the shuttle 17. The length of the transport rollers 2008 is equal to or slightly greater than the length of a container 3 (here the length of a container is its dimension in the longitudinal direction of the shuttle).

[0434] The shuttle 17 includes a mechanism for coupling it to a drive cable 42 enabling it to be pulled by the cable 42, which runs between rails 40, parallel to the latter. A guide structure 2001 of the cable 42 is mounted on a support 2000 shared with the rails 40.

[0435] The cable 42 forms a loop, with an outgoing section 42b and a return section 42a. As shown in FIG. 78, the guide structure 2001 may include a bottom roller 2001a on which the return section 42a of the cable 42 rests and an upper roller 2001b on which the outgoing section 42b of the cable 42 rests, with which the shuttles 17 can come to be engaged to be driven on the rails 40, the two rollers 2001a and 2001b preferably having parallel rotation axes spaced sufficiently close together in the vertical direction for the return section 42a to come into contact both with the upper rollers 2001b and lower rollers 2001a.

[0436] The support 2000 may be of arcuate shape, concentric with the wall 2002 of the micro-tunnel 2 and may bear directly on the latter, as shown in FIGS. 77 and 78.

[0437] The peripheral frame of the chassis 11000 of the shuttle 17 defines housings between, on the one hand, the front crossmember 11003 and the adjacent crossmember 11005, and, on the other hand, the rear crossmember 11004 and the adjacent crossmember 11006, respectively receiving a front axle assembly 2006 and a rear axle assembly 2007.

[0438] The front axle assembly 2006 and the rear axle assembly 2007 each include for example, as shown, six wheels comprising two support wheels 2011 that come to bear on the rails and support the weight of the shuttle 17 and four lateral guide wheels 2010, as shown in FIG. 79. The support wheels 2011 rotate about a horizontal axis and the lateral guide wheels 2010 rotate about a vertical axis.

[0439] Each of the axle assemblies includes a main arm 2080 and two lateral arches 2090 connected to each of the ends of the main arm 2080.

[0440] As shown in FIG. 79, the main arm 2080 is divided at each of its ends into two branches 2081 the ends of which are fixed to the lateral arches 2090.

[0441] Each lateral arch 2090 is fixed at each of its ends to the chassis 11000 at the level of the front crossmember 11003 and the adjacent crossmember 11005 or at the level of the rear crossmember 11004 and the adjacent crossmember 11006.

[0442] A yoke 2100 is connected in an articulated manner to the middle of each lateral arch 2090 so as to be able to pivot about a vertical axis. A support wheel 2011 is mounted on this yoke 2100.

[0443] A support structure 2110 is connected in an articulated manner to the middle of each lateral arch 2090 so as to be able to pivot about a vertical axis. Two guide wheels 2010 are mounted on this support structure 2110.

[0444] As shown in FIG. 79, the front axle assembly 2006 includes a central arch 2120 that is fixed to the middle of the main arm 2080, this central arch 2120 carrying the mechanism for coupling it to the cable 42.

[0445] The mechanism for coupling it to the cable 42 includes a clamp 2130 configured to be coupled to and uncoupled from the cable 42 and a structure mobile relative to the fixed central arch 2120 to which it is fixed.

[0446] This mobile structure includes two uprights 2140 each of which carries at least one actuator roller 2150. The clamp 1230 includes at least two jaws connected by a transmission mechanism on the one hand to the fixed central arch 2120 and on the other hand to the mobile structure.

[0447] The transmission mechanism is arranged so that movement of the mobile structure relative to the fixed central arch 2120 is accompanied by clamping of the jaws onto the cable 42 or releasing them from the cable 42, depending on the upward or downward movement of the mobile structure.

[0448] The mechanism may include at least one elastic member 2170 for returning the jaws of the clamp 1230 to the clamping position. This elastic return member 2170 may be a coil spring, oriented vertically, the lower end of which is fixed, as shown in FIG. 79.

[0449] For example, actuation of the clamp 2130 is achieved by pressing the two actuator rollers 2150 simultaneously.

[0450] The rails 40 extend in a longitudinal direction of the micro-tunnel 2. As shown in FIG. 78, each of the rails 40 has an I-shape cross section with an upper horizontal bearing face, a lower horizontal bearing face and a vertical wall connecting the upper and lower bearing faces. The lower bearing faces bear on the support 2000 and the support wheels 2011 roll on the upper horizontal bearing faces. The guide wheels 2010 bear on an internal face of the vertical wall.

[0451] There has been shown in FIGS. 80 and 81 an example of a shuttle 17 including a chassis 11000 sized to receive six containers 3 disposed in two rows of three containers 3, a row extending in the longitudinal direction of the shuttle 17. The shuttle 17 includes three receiving spaces 2012, each space 2012 being able to receive two containers 3 disposed side by side. The shuttle 17 includes a front barrier 2003 and a rear bather 2004 together with two intermediate barriers 2005 disposed between the spaces 2012.

[0452] Each shuttle 17 may include a mechanism for locking a container 3 onto the shuttle 17, as shown in FIGS. 82 to 87.

[0453] This locking mechanism may be activated and deactivated automatically, respectively by putting into place and removing the base 200 of the container or containers 3.

[0454] A locking mechanism of this kind is associated with each receiving space 2012 of the shuttle 17.

[0455] Two adjacent spaces 2012 may have locking mechanisms having elements in common.

[0456] The locking mechanism may include for each space 2012 of the shuttle 17 two opposite rows of locking elements 2020. Each row may include two or four locking elements 2020. The locking elements 2020 of two opposite rows may be arranged in a quincunx, as shown in FIG. 86.

[0457] Each locking element 2020, mobile relative to the platform 1000, may include at its upper end a hook 2030 configured to come into contact with the base 200 of the container 3 in such a manner as to lock the latter to the receiving space 2012 concerned. For example, this hook 2030 engages over a corresponding relief produced on the base 200, for example a notch (not represented). The engagement of the hook 2030 in the notch in the base 200 participates in retaining the container 3 on the platform 1000.

[0458] Each locking element 2020 may be mobile in rotation relative to a transverse axis of the platform 1000.

[0459] Each locking element 2020 is articulated at approximately mid-height on a support means 2019 fixed to the chassis 11000 of the shuttle 17. In the example considered in FIG. 83 each locking element 2020 is articulated on a yoke 2019 fixed to an intermediate crossmember 11007 of the chassis 11000.

[0460] The locking elements 2020 of the same row are articulated at their lower ends on a shaft 2017, that shaft 2017 being horizontal and oriented in the transverse direction of the shuttle 17.

[0461] Of the two opposite rows of locking elements 2020 of a receiving space 2012, one row includes actuator rollers 2018 carried by the shaft 2017 and the distance between these rollers 2018 may be identical.

[0462] In the example considered, the row of locking elements 2020 positioned in the vicinity of the intermediate barrier 2005 includes actuator rollers 2018 carried by the shaft 2017, in particular three rollers 2018, and the row of locking elements 2020 positioned in the vicinity of the front barrier 2003 or the rear barrier 2004 does not include rollers 2018 carried by the shaft 2016.

[0463] The movement of the shaft 2017 that carries the rollers 2018 is transmitted to the locking elements 2020 of the opposite row by way of linkages 2015 that are articulated at their ends to the shaft 2017 and to the locking elements 2020 of the opposite row.

Unlocking the Containers

[0464] The rollers 2018 are actuated by one or more actuators (not represented) so as to push the rollers 2018 in the direction away from the intermediate barrier 2005.

[0465] The actuator or actuators may be outside the shuttle 17, for example at the level of an exchange or scheduling station.

[0466] The rollers 2018 being fixed to the shaft 2017, actuation thereof enables the shaft 2017 to be pushed in the direction away from the intermediate barrier 2005, which enables driving in rotation of the locking elements 2020 that are connected to the shaft 2017 so as to move those locking elements 2020 to the unlocked position, as shown in FIGS. 82 and 84.

[0467] The movement of the shaft 2017 in the direction away from the intermediate barrier 2005 also enables actuation of a mechanism with links 2021 including two links 2021 connected at one of their ends to the adjacent shafts 2017 and at the other of their ends to at least one return member 2014, in particular a coil spring, oriented along a vertical axis.

[0468] These springs 2014 may be situated in the vicinity of the intermediate barriers 2005 and in part accommodated inside the latter.

[0469] Two adjacent spaces 2012 of the platform 1000 may share the springs 2014 of their locking mechanism.

[0470] The actuation of the links 2021 enables compression of the springs 2014, as shown in FIGS. 82 and 84.

[0471] The rods 2015 enable the movement of a shaft 2017 to be transmitted to the locking elements 2020 of the opposite row so as to move those locking elements 2020 to the unlocked position, as shown in FIG. 82.

[0472] Thus the locking elements 2020 of the two opposite rows go to the unlocked position, which enables a container 3 to be unlocked from the platform 1000, in particular when the latter arrives at its destination.

[0473] As shown in FIGS. 82, 83, 86 and 87 the locking mechanism for a space 2012 of the platform 1000 may include two rods 2015.

[0474] A single actuator (not represented) can enable unlocking of the locking elements 2020 of all of the receiving spaces 2012 of the shuttle 17.

[0475] Alternatively, the containers 3 are not unlocked by actuating the rollers 2018 but by actuating the linkage mechanism. For example an actuator comes to compress the return member 2014 differently so as to unlock the locking elements 2020.

Locking the Containers

[0476] The return force of the spring 2014 enables the links 2021 to pull the shaft 2017 toward the intermediate barrier 2005, which enables driving in rotation of the locking elements 2020 that are connected to the shaft 2017 so as to move those locking elements 2020 to the locked position, as shown in FIGS. 83, 85 and 86.

[0477] The rods 2015 transmit the movements of the shaft 2017, positioned in the vicinity of the intermediate barrier 2005, to the locking elements 2020, positioned in the vicinity of the front barrier 2003 or the rear barrier 2004, so as to move those locking elements 2020 to the locked position, as shown in FIG. 83.

[0478] The locking elements 2020 of the two opposite rows are therefore in the locked position, that is to say in contact with the base 200 of the container 3, which enables locking of the container 3 onto the platform 1000, in particular when it is in its final position on the platform 1000.

[0479] As shown in FIGS. 77, 80, 81 and 84 to 87, each space 2012 of the platform 1000 may include one or more friction wheels 2009 the rotation of which drives one or more transport rollers 2008 of the receiving space 2012 concerned via a transmission chain (not represented). This enables loading and unloading of a container 3 to be facilitated.

[0480] The friction wheels 2009 are positioned at the ends of the transport rollers 2008, preferably in the vicinity of the intermediate barriers 2005 of the platform 1000. In the example considered, each receiving space 2012 includes two friction wheels 2009, the latter being situated in particular at the level of the first and last transport rollers 2008 of the space 2012 concerned.

[0481] Each of the friction wheels 2009 includes a friction band enabling it to be driven in rotation by friction. For example, these friction wheels 2009 are coupled to drive wheels of an exchange or scheduling station. These drive wheels are rotated by drive means and come to bear on the friction wheels 2009 to drive them in rotation. Alternatively, the rollers are motorized by motor means present on the shuttle 17.

[0482] Of course, the invention is not limited to the example shown.

[0483] Different particular embodiment features described separately may be combined.

[0484] The container may be provided with closure means other than those that have just been described. For example, the container 3 has no door at the front or by way of closures includes one or more removable bars 1200 as shown in FIG. 29, or even a simple chain as shown in dashed line in FIG. 29.

[0485] The barriers may be constructed differently and for example in the form of solid or perforated, single or multiple partitions. Those partitions may be provided with slides or not.

[0486] Where appropriate the slides may be provided with sliding strips of a low coefficient of friction material. The axle assemblies of the shuttle need not include shock absorbers.

[0487] Alternatively, shock absorbers are provided to attenuate the vibrations linked to rolling.
