Machine for processing individual sheets
A machine for processing individual sheets comprises at least one processing station, in particular in inkjet printing station, and a transport system (100) for transporting the individual sheets through the processing station, along a transport direction. The transport system (100) comprises at least one gripper conveyor (150) movable along the transport direction, for gripping one of the individual sheets defining a sheet position in transport direction. The transport system (100) further comprises at least one support conveyor (190) movable along the transport direction for supporting a region of the individual sheet, wherein the support conveyor (190) comprises a vacuum system for supporting the individual sheet on an interacting surface of the support conveyor, the vacuum system comprising a plurality of orifices in the interacting surface. The machine allows for efficient and flexible handling of individual sheets, in particular large format sheets of materials such as corrugated cardboard or other materials that have a certain degree of inherent stability.
Detecting and processing multi feeding
An example print medium supplying apparatus includes a print medium transporting device to pick up a print medium loaded in a loading portion and transport the picked-up print medium, a print medium alignment portion to align a leading end of the transported print medium, a first sensor to sense the print medium that passes through a feed roller of the print medium transporting device, and a processor to, based on a measured value with respect to the print medium sensed by the first sensor and a multi-feeding determination reference value corresponding to a sheet of the print medium, detect multi-feeding of the print medium and process the detected multi-feeding by controlling the print medium transporting device and the print medium alignment portion.

Dynamic scale for flat goods transported their sides, and control method therefor
In a dynamic scale and control method for flat goods transported on their sides, use an input-side first assembly for thickness measurement, a transport device having transport belts arranged on a weighing plate. A control processor starts a length measurement and the driving of the transport belts, and starts a thickness measurement and implement a dynamic weighing process during the transport of a first flat good. A next flat good is supplied to the input of the dynamic scale if a valid weight measurement result is present for the predecessor good, and ejection of the predecessor good or end of the weight measurement occur if a third sensor at the input of a takeoff device of the dynamic scale detects the leading edge of the predecessor good, and a check yields that no valid weight measurement result is present for the predecessor good.
SHEET DISCHARGE DEVICE AND SHEET DISCHARGE METHOD
A sheet discharge device includes a sheet discharge roller pair composed of an upper roller and a lower roller; and a placement tray, arranged below the sheet discharge roller pair, configured to place a sheet discharged from the sheet discharge roller pair. The device further includes a sheet presser configured to be held on a sheet discharge side of the upper roller in a movable manner and pushed up by a sheet front end to be discharged, and depress a sheet rear end with the dead weight thereof after the sheet rear end passes through a nip between the sheet discharge roller pair. The device additionally includes an auxiliary tray that is movable between a first position where the sheet rear end depressed by the sheet presser is caught and a second position where the sheet rear end is released from the sheet presser.

PRINTING APPARATUS, CONTROL METHOD FOR PRINTING APPARATUS, AND CONVEYANCE APPARATUS
A printing apparatus includes a first conveyance unit provided in a conveyance path and configured to convey a print medium, a second conveyance unit provided upstream of the first conveyance unit in the conveyance path and configured to convey a print medium, a drive source configured to drive the first conveyance unit and the second conveyance unit, and a control unit configured to control the drive source so as to execute a conveying operation in which a second print medium succeeding a first print medium is conveyed by the second conveyance unit while the first print medium is conveyed by the first conveyance unit. The control unit is configured to switch drive control of the drive source in accordance with a position of the second print medium when starting the conveying operation.
SHEET DISCHARGE APPARATUS AND IMAGE FORMING APPARATUS
A sheet discharge apparatus includes: a discharger that discharges a sheet; a loading part on which the sheet discharged from the discharger is loaded; an abutment member that abuts against a rear end of the sheet in a direction of discharging to align the sheet loaded on the loading part; a pull-back member that performs a pull-back operation by contacting with the sheet discharged from the discharger to pull back the sheet toward the abutment member; and a hardware processor that controls the pull-back member. The hardware processor performs the pull-pack operation on a sheet bundle when determining that the sheet bundle bound by a binder is discharged from the discharger.
