A sheet behavior monitor for a sheet processor includes: a folding machine processing a sheet; and a camera taking an image once for each signature (Wb) folded by the folding machine. The camera takes every image at a folding machine rotation phase different from that of the image immediately before taken.

Sheet behavior monitor for sheet processor

A sheet processing apparatus including a sheet supply device, a first cylinder which includes at least one gripper device, a processing device, a sheet discharge device, and conveyance devices. The conveyance devices include a plurality of gripper devices including at least one reversing gripper device. The conveyance devices also include a second cylinder and reversing swing arm shaft pregripper. The second cylinder grips and conveys one edge of the sheet by one gripper device of the plurality of gripper devices. The reversing swing arm shaft pregripper is supported to be swingable between the first cylinder and the second cylinder, receives by the reversing gripper device the other edge of the sheet conveyed by the second cylinder, and transfers the received other edge of the sheet to the gripper device of the first cylinder by a gripping change.

Sheet processing apparatus having reversing swing arm shaft pregripper

A folding machine includes: pairs of upper and lower downstream-side conveying belts (B), the pairs being provided at intervals in a direction perpendicular to a conveying direction of a signature (Wb) and conveying the signature while holding the signature therebetween; stoppers () provided between the downstream-side conveying belts and stopping the signature conveyed by the downstream-side conveying belts by contacting therewith; and a chopper blade () folding the signature stopped by the stoppers () in a direction parallel to the conveying direction. In the folding machine, a pair of right and left cameras (A andB) are provided, which take images respectively of ranges where a conveying direction leading edge of one side edge and a conveying direction leading edge of the other side edge, the side edges being parallel to the conveying direction of the sheet, are decelerated or stopped by contacting with the stoppers ().
