A machine (100) for unstacking objects (10) includes a belt mechanism (110, 120, 121, 130) having a conveyor belt (110), a first drive mechanism (115) for driving the conveyor belt (110), a second drive mechanism (120, 121) for shifting the conveyor belt (110) between a forwarded position and a retracted position, and a third drive mechanism (130) for adjusting a height position of the conveyor belt (110). Further, the machine (100) includes a gripper mechanism (150, 160) having a gripper (150) and a fourth drive mechanism (160) for moving the gripper (150) between different height positions. A controller of the machine (100) is configured to control the gripper mechanism (150, 160) to grip an end portion of an uppermost object (10) of a stack (20) and lift the end of the uppermost object (10), to control the second drive mechanism (120, 121) and the third drive mechanism (130) to position a forward end of the conveyor belt (110) below the lifted end portion of the uppermost object (10), and to control the first drive mechanism (110) and the second drive mechanism (120, 121) to operate in a coordinated manner by shifting the conveyor belt (110) towards the forwarded position while at the same time driving the conveyor belt (110) in a backwards direction to draw the uppermost object (10) onto the conveyor belt (110).

The present invention relates to a handling installation for handling sheets of cardboard or similar material applicable for implementation thereof in an automated production facility, comprising a first receiving station (1) configured to receive packages formed by cardboard sheets, each of the sheets being defined by four sides, and a second distribution station (2) in which the sheets are delivered face-down coming from the receiving station by means of sheet handling means. The first and second stations comprise modules that are independent from each other, the handling means comprising a robot arm provided with a head with clamping means to hold the package of sheets on any of the four sides, the head having a hinge point that can be coupled to a robot arm, capable of conveniently moving and orienting the clamping means in any of the coordinate axes, the robot arm being mounted on a base that is independent with respect to the first and second stations.

In a device for detecting a paper splice part of a cardboard sheet and a device for producing a cardboard sheet, the device for detecting a paper splice part of a cardboard sheet, which detects a sheet paper splice part of a cardboard sheet that has a first sheet, a corrugated second sheet, and a third sheet bonded together, comprises: a sheet paper splice detection unit that detects the sheet paper splice part on the basis of the shape of the sheet and that is placed between a position at which sheets are spliced and a position at which the sheets are bonded in a sheet carrying direction; a marking device that marks the sheet paper splice part on the downstream side of the sheet paper splice detection unit in the sheet carrying direction; and a mark detection device that detects the mark on the downstream side of the marking device in the sheet carrying direction.

A station for picking up and delivering shaped sheets that define box-like bodies of different types includes a magazine for the sheets and at least one handling element for at least one sheet at a time. The magazine accommodates a plurality of mutually aligned and juxtaposed sheets and the at least one handling element includes an end bracket provided with at least one grip element and at least one assembly with arms which are articulated with respect to the bracket and are independently movable with respect to a fixed frame. The bracket can move between a first configuration of alignment with the end sheet accommodated in the magazine, in the condition where the at least one grip element is in contact with the end sheet, and a second configuration of alignment with a conveyance line of the sheets which corresponds to the delivery region.

A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

The present invention relates to a method of dispensing individual sheets and a sheet dispensing system. The sheet dispensing system comprises a frame assembly (14), a reel loading station (20), a sheet dispenser station (40) and a delivery station (70) connected to the sheet dispenser station (40). The reel loading station (20) includes a supply reel (22) of a cellulose fiber based web and a support for supporting the supply reel. The sheet dispenser station includes a feeding mechanism (50) serving to receive the cellulose fiber based web from the reel loading station (20) and a cutting mechanism (60) having a reciprocating cutter assembly for cutting the cellulose fiber based web into individual sheets. The delivery station includes a delivery table (71) connected to the sheet dispenser station (40). The reel loading station (20) or the sheet dispenser station (40) or delivery station (70) further comprises a smoothing mechanism (100) to compensate for the curvature of the cellulose fiber based web and provide non-curved individual sheets (28).
