The present invention relates to an apparatus (1) for handling and collecting a plurality of substantially bi-dimensional objects (100) comprises: a conveyor (2), arranged to receive the bi-dimensional object from a source, and configured to provide a holding force (F) to draw and hold the bi-dimensional objects from above; a disengagement device (4), configured to temporarily oppose the holding force on at least a portion of the conveyor, to disengage the bi-dimensional objects from the conveyor, causing the fall of the bi-dimensional objects towards a collecting area (5).

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).

A diverting system is proposed for diverting boxes from normal production flow. One embodiment comprises a diverter with a diverter surface, a diverter cam in contact with the diverter, a diverter cam shaft connected to the top diverter cam such that rotation of the diverter cam shaft causes rotation of the diverter cam, and an electric motor connected to the diverter cam shaft and configured to rotate the diverter cam shaft. The diverter cam is configured to control position of the diverter as the diverter cam rotates such that rotation of the diverter cam causes the diverter surface to move from a position above normal production flow to a diverting position within the normal production flow.

The present invention relates to an automatic image positioning system for a sheet material.
