A conveying device includes: a rotation part to which a holding part configured to hold a material to be conveyed is attached and configured to rotate in a circumferential direction to convey the material to be conveyed; a conveying roller that is provided with a recess for accommodating the holding part to convey the material to be conveyed; and a guide member including a guide portion configured to guide the material to be conveyed on a downstream side of the conveying roller, and a space in an intersecting direction intersecting the circumferential direction with respect to the guide portion, the space where the holding part moving by rotation of the rotation part passes through.

Example printer finishing apparatus are described herein. An example printer disclosed herein includes an alignment guide, a track to align a sheet relative to the alignment guide, a clamp to move between a raised position and a lowered position relative to the sheet, and a force applicator coupled to the clamp. The force applicator is to cause the sheet to engage the alignment guide when the clamp is in the lowered position.

A medium stacking device includes an intermediate stacker that receives a medium treated by a treatment portion, and a first alignment member as an example of a contact portion, that is configured to move between a first position for performing an alignment operation on the medium on the intermediate stacker, and a second position that is separated further from the leading edge of the medium than is the first position. Furthermore, the medium stacking device is provided with a stacking portion that stacks the medium discharged from the intermediate stacker. The medium discharged from the intermediate stacker is stacked on the stacking portion after a leading edge contacts the first alignment member positioned at the second position.

The invention relates to an inspection device (6) for inspecting sample blanks (P) for a processing machine (1) for processing elements in sheet form, the processing machine (1) comprising a plurality of work stations (300, 400, 500, 600) including at least one waste removal station (600) comprising a removal belt (93; 94), the inspection device (6) being characterized in that it comprises an optical monitoring device (7) configured to determine a fault with the quality of a sample of blanks (P) laid flat on the removal belt (93; 94).

The present invention also relates to a waste removal station, a processing machine for processing elements in sheet form, and to a method for the quality control of sample blanks.

The invention relates to an ejection device (2) for ejecting sample blanks (P) for a processing machine (1) for processing elements in sheet form, the processing machine (1) comprising: a plurality of work stations (300, 400, 500, 600) including at least one waste removal station (600), and a conveying device (70) comprising a plurality of gripper bars (75) configured to drive the elements in sheet form through the work stations (300, 400, 500, 600), the ejection device (2) being characterized in that it comprises at least one actuating element (3) able to move between: an inactive position in which the at least one actuating element (3) is positioned away from the path of the gripper bar (75), and an active position in which the at least one actuating element (3) is positioned on the path of the gripper bar (75), the at least one actuating element (3) being configured to collaborate with the gripper bar (75) as the gripper bar (75) passes by, so as to open the gripper bar (75) and eject, flat, a sample of blanks (P).

The present invention also relates to a waste removal station, a processing machine for processing elements in sheet form, and to a method for ejecting blanks samples in a machine for processing elements in sheet form.

The present invention discloses gripper bar locking apparatus and sheet processing device. In particular, the present invention discloses a gripper bar locking apparatus, which is configured to lock and adjust a position of a gripper bar, comprising: a supporting plate having a distal end and a proximal end; a lever portion, a distal end of which is pivotally mounted on the proximal end of the supporting plate; a cartridge movably mounted on a proximal end of the lever portion and provided with a gripper bar abutment; and an adjusting means provided on the cartridge and configured to adjust a position of the cartridge with respect to the lever portion. Further, the present invention relates to the sheet processing device including the gripper bar. By using the gripper bar locking apparatus, the adjustment of the position of the gripper bar is facilitated.

In an example, a clamp may include a roller disposed on a swingarm, a slide disposed on the swingarm that may apply friction against the roller in a first position and in a second position, a cam to engage with the slide, and a latch to retain the slide in the second position. The slide may move from the first position to the second position as the slide moves along the cam, and the slide may apply a greater friction against the roller in the second position than in the first position.

In one example, a system can include a media pathway to transport a media into a stacking region, a clamp pathway to move a clamp along the clamp pathway, and a registration surface. The registration surface may be positioned between an edge of the media pathway and the clamp pathway.

A sheet stacking apparatus includes a sheet alignment mechanism configured for aligning a sheet in a predetermined reference position; a gripper arrangement configured to grip the aligned sheet at at least two spaced-apart points of the sheet and to release the sheet on a stack; and a holder configured to hold the sheet in position on the stack while the gripper arrangement releases the sheet. The gripper arrangement is movable along a predetermined trajectory for moving the sheet from the reference position to a stacking position.
