Provided is a recording device that includes a recording head that ejects a liquid, a discharge unit that discharges a recorded recording medium, a discharge tray that receives a discharged recording medium, a first blowing unit that is disposed above the discharge unit and blows air toward one surface of the recording medium to be discharged to the discharge tray, and a second blowing unit that is disposed between the discharge unit and the discharge tray and blows air toward the other surface of the recording medium to be discharged to the discharge tray, and a control unit that controls the first blowing unit and the second blowing unit, in which deformation of the recording medium to be discharged is suppressed by the wind of the first blowing unit and the second blowing unit and the recording medium is discharged.

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 postprocessing device includes a sheet conveying passage, a sheet tray, an inlet guide, a processing device, and a blowing device. Though the sheet conveying passage, a sheet on which an image has been formed is conveyed. The sheet tray is arranged downstream of the sheet conveying passage and has sheets stacked on it. The inlet guide is arranged at the downstream end of the sheet conveying passage and guides a sheet to the sheet tray. The processing device performs predetermined processing on a sheet stacked on the sheet tray. The blowing device blows air, from the upstream side in the sheet conveying direction, between the top face of the top-most sheet in the sheets stacked on the sheet tray and the bottom face of the subsequent sheet sent from the inlet guide into the sheet tray.

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.

Please add the Abstract of the Disclosure, as set forth on the separate accompanying sheet. This Abstract of the Disclosure is essentially the same, in content, as the Abstract which is a part of the published PCT application, WO 2017/202762A1. No new matter is being presented by the addition of this Abstract of the Disclosure.

An apparatus and method for the post-processing of successively following, sequentially printed sheets, includes a conveyor, a folding table, a folding sword, a folding roller pair, at least one pressing-down mechanism, and a machine control that is operatively connected to the folding sword and the pressing-down mechanism. The pressing-down mechanism includes at least one mechanical braking element which acts in the region of the back edge onto the top side of the printed sheet to be positioned on the folding table. The stationary folding sword includes a compressed-air device with at least one outlet opening for compressed air which is focused onto a folding roller gap. The folding table forms a gathering device for at least two successively following printed sheets. A sensor, arranged in a region of the conveyor, is operatively connected to the machine control and functions to detect the printed sheets, transported with the conveyor.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.

A sheet stacking system includes a conveyor having a discharge end, a hopper at the discharge end configured to receive the sheets ejected from the discharge end and guide the sheets as they fall in a cascade path onto a platform associated with the hopper, the falling sheets forming a main stack on the platform, the hopper including a backstop facing the discharge end of the conveyor such that the sheets ejected from the discharge end impact against the backstop before forming the main stack, and a first accumulator having at least one first support extending through the backstop and shiftable from a retracted position to an extended position, the at least one first support being movable vertically relative to the backstop in the extended position from a raised location outside the cascade path to a lowered location in the cascade path.

The sheet postprocessing device includes a sheet conveyance path, a sheet tray, a carry-in guide, a processing part, a discharge member, a blower device, and an intermediate conveyance part. The sheet tray includes an upstream-side stacking part. The intermediate conveyance part is provided at a position within a range from the upstream-side stacking part to the downstream-side stacking part in a conveyance direction, and allows a sheet to pass therethrough below the processing part. The intermediate conveyance part is made up by including an upstream part including a first clearance through which the sheet passes, and a downstream part placed on a downstream side of the upstream part and including a second clearance through which the sheet passes. A size of the second clearance in a planar direction perpendicular to a surface of the sheet is wider than a size of the first clearance in the planar direction.

A post-processing device is provided with a post-processing unit which performs post-processing of a recording medium on which recording is performed, a transport path through which the recording medium is transported, or a deformation suppressing unit which suppresses deformation of the recording medium on a mounting unit on which the recording medium is mounted, in which the deformation suppressing unit is controlled based on a predetermined parameter related to recording processing with respect to the recording medium.
