A method for depositing wet printed sheets and forming a sheet stack in a delivery of a printing machine. An auxiliary stack which is separate from the sheet stack has sheet-shaped intermediate layers that are usable as moisture barriers in the sheet stack. A plurality of sheets are stacked on top of one another to form a first section of the sheet stack. Then an intermediate layer is moved from the auxiliary stack onto the section of the sheet stack. A plurality of sheets are stacked on top of one another and on the intermediate layer to form a further section. The intermediate layer is thus arranged in the sheet stack between the first section and the further section. The placement of the intermediate layers provides a way of reducing or even eliminating quality losses in sheets and/or sheet stacks caused by moisture and moisture exchange.

The present invention provides a sheet stacking device, a counter-ejector, and a carton former and is provided with: a hopper unit that stacks cardboard boxes; feed rollers that feed a cardboard box to the hopper unit; a first blower device that blows air from above the hopper unit toward the cardboard box fed by the feed rollers; and a second blower device that blows air between the cardboard box stacked in the hopper unit and the cardboard box fed by the feed roller.

A sheet stacking device includes a hopper unit on which box making sheet material is stacked; an ejection unit that ejects the sheet material to the hopper unit; a first blowing device that is disposed above the downstream side of the hopper unit in the transfer direction of the sheet material and that presses the sheet material downward by blowing air; a pressing device that is disposed above an upstream side of the hopper unit in the transfer direction of the sheet material and that presses the sheet material downward; and a control device that controls an operation of the first blowing device pressing a front end of the sheet material downward, and controls an operation of the pressing device so as to press a rear end of the sheet material downward with a pressing force higher than that applied to the front end of the sheet material.

To provide a marking device that enables to easily find a tag determined as defective (RFID error, etc.) among a plurality of tags that are stacked or the like. The marking device to use with a sheet includes cut and raising part for forming, as a failure process, a cut and raised section to be positioned at an edge of the sheet having been found the defect.

A post-processing apparatus includes: a cutter that cuts a paper sheet into a plurality of pieces; and a hardware processor that causes the cutter to cut out a product formed in part of the paper sheet and a partition sheet formed in another part of the paper sheet, wherein the hardware processor causes the partition sheet and the product to be ejected to the same ejection destination at timings different from each other, and the partition sheet is formed between jobs that cause the product to be generated.

A sheet post-processing device includes: a loading assist mechanism including a flapping member, a pressing member, a first power transmission mechanism that pivots the flapping member from a first ready-to-pivot position, a second power transmission mechanism that pivots the pressing member from a second ready-to-pivot position, a rotary member that transmits, during rotation in a first direction, power to the first power transmission mechanism, and transmits, during rotation in a second direction, power to the second power transmission mechanism, and a drive source that rotates the rotary member; and a control device that controls the drive source to control an angle of rotation of the rotary member in the first direction, thus controlling an angle of pivoting of the flapping member, and controls the drive source to control an angle of rotation of the rotary member in the second direction, thus controlling an angle of pivoting of the pressing member.

A control apparatus includes a processor and a memory to control a system having an image forming apparatus and a sheet discharge apparatus. Executing a memory store program causes the control apparatus to receive configuration information of the system and generate a system configuration image, receive stacking state information and generate a sheet bundle image, display a screen, receive job identification information of an image forming job of sheets to be picked up, and display a thumbnail image. The stacking state information includes a stacking amount of sheets stacked on a sheet stacking tray. The sheet bundle image represents the sheets stacked on a sheet stacking tray based on the stacking state information. The system configuration image and the sheet bundle image are combined in the screen. The thumbnail image is based on receiving the job identification information.
