Apparatus for automatically unstacking a pallet on which at least two stacks of blanks are arranged. The apparatus comprises an unstacking station which is configured for receiving a pallet on which are arranged at least two stacks of blanks in collapsed condition. The unstacking station is further configured for taking off one by one individual blanks from the at least two stacks of blanks which are on a pallet received in the unstacking station. The apparatus further includes a feed track for conveying pallets. The feed track links up by a discharge end with the unstacking station for the purpose of feeding a pallet with stacks of blanks to be unstacked to the unstacking station. Further, the apparatus includes a blank main discharge assembly for discharging individual blanks to a further processing station.

A removable raised tray system for a printing system generally includes a removable tray operatively arranged to receive print media thereon. The removable tray includes an upper tray surface having an electrically conductive material, a lower tray surface, and at least one tray leg that is connected to the removable tray, which is configured to support the removable tray at a position that is raised relative to a platform surface of a printer feeder or stacker. The at least one leg includes a releasable fastening assembly, such as a rare earth magnet, that releasably secures the removable tray to the platform surface thereby allowing the tray to easily attached and removed from the printer feeder or stacker. The electrically conductive material of the tray surface and the platform surface are electrically conductively connected to one another so as to prevent the build-up of static electricity.

The rotational pin and the lock pin are laterally provided in the right and left first brackets that are fixed to the right and left side surfaces of the sheet loading tray respectively, and furthermore, the right and left second brackets are fixed to the right and left of the one side surfaces of the casing. When the sheet loading tray reaches the sheet loading position, the lock pin is made to enter the sheet loading tray lock groove formed on the right and left second brackets to thereby lock and hold the sheet loading tray at the sheet loading tray storage position, along with an action of rotating the sheet loading tray about the rotational pin fitting into the sheet loading tray support groove formed on the right and left second brackets from the sheet loading position to the sheet loading tray storage position.

Provided is a sheet folding device which can reduce the pellet exchange frequency and an operation stop time accompanying a pallet exchange. The sheet folding device includes: (a) first movement unit disposed to be able to be raised/lowered above a placement region; (b) a second movement unit which is supported by the first movement unit and reciprocates along the placement region in a first direction; and (c) a sheet discharge device which is supported by the second movement unit and has a sheet discharge port facing the placement region, the sheet discharge port reciprocating along the placement region in a second direction crossing the first direction. Sheets continuous in the longitudinal direction are discharged from the sheet discharge port of the sheet discharge device so that the width direction of the sheets crosses the second direction.

A supply apparatus for paper of which one side is printed and another side is not printed and which is used for a single-side printer much cheaper than a double-side printer and having a smaller occupied area than that of the double-side printer is improved to be easily, promptly, safely, and surely set. A supply apparatus reverses a plurality of sheets of stacked paper of which one side has been printed so that a non-printed surface comes to an upper surface and supplies the stacked paper to a printer again. The non-printed paper supply apparatus for the single-side printer includes two palettes which sandwich and hold the stacked paper from upper and lower sides, a plurality of alignment holding tools which is provided between the palettes and is adjusted according to a volume of the stacked paper, a pair of fastening and reversing tools including reversing bars in which reversing shafts for reverse are formed on sides of the palettes opposite to each other, and a pair of reverse assisting stands which pivotally support reversing shafts of each fastening and reversing tool. The alignment holding tool and the fastening and reversing tool are respectively fixed to upper/lower palettes with fixing tools which are attached/detached in a single operation.

A method and a device for combining an auxiliary stack and a main stack include a rake carrying the auxiliary stack and being abruptly movable out of a stack area to prevent sheets that contact the rake from being entrained and to preserve the structure of the stack. A sheet-fed printing press or sheet punching machine having the device is also provided.

A method for moving a stack of products by a robot. The robot has an articulated arm and at least one gripper disposed on the articulated arm for gripping the stack of products. The stack of products is turned, before being moved by the robot, with a pivoting device that is separate from the robot. The stack of products is turned about a horizontal axis and the stack of products, while out of the horizontal orientation, is aligned and/or straightened in one direction and/or straightened in two mutually orthogonal directions and/or vibrated and/or aerated and/or modified from a fanned-out stack of products to become an unfanned stack of products. The robot then takes the stack from the pivoting device and subsequently moves the stack.

Personnel saving of a process from a printer to a sheet processing machine is achieved. A general printing management device is connected to be communicable with a conveyance management device that manages a plurality of automatic guided vehicles each conveying a stacker in which paper ejected from a printer is stackable. The general printing management device generates conveyance instruction information for conveying a stacker in which paper ejected from the printer is stacked from a sheet receiving position of the printer to a sheet supply position of a next processing machine, based on job information in which a manufacturing process procedure for manufacturing a printed product is registered, and transmits the conveyance instruction information to the conveyance management device.
