A sheet bundle discharging apparatus, including: a guide unit configured to guide a sheet bundle with a spine as a leading end; a receiving unit configured to receive the spine of the sheet bundle guided by the guide unit; and a discharging unit configured to discharge the sheet bundle, wherein the receiving unit includes: a first surface configured to receive the spine at a first position; a second surface configured to push the sheet bundle in a rotation direction of the receiving unit; and a third surface configured to regulate a movement of the sheet bundle in the rotation direction while the receiving unit rotates from the first position to a second position, and wherein a friction coefficient between the sheet bundle and the third surface in a direction away from the first surface is larger than a friction coefficient between the first surface and the sheet bundle.

A transport device stacks partial book blocks along a transport path formed of transfer paths, and includes: a first transfer path at a start of the transport device; a first separating element downstream of the first transfer path and upstream of a second transfer path; a second separating element downstream of the second transfer path and upstream of a processing machine that is operatively connected to the transport device; and a transition path which is arranged either upstream or downstream of the second separating element and within which a book block product that is to be introduced therein is transferable from a transport position where it is lying flat and into a transport position where it is guided standing up. At least one of the transfer paths is equipped with at least one sheet stack feed unit and/or at least one collator-feeder.

A paper sheet stacking apparatus, includes: a first tray that stacks a paper sheet; a sheet discharger that discharges a paper sheet supplied from the outside of the apparatus to the first tray; a second tray that receives the paper sheet stacked on the first tray and discharges the received paper sheet to the outside of the apparatus; and a hardware processor that controls operation states of the first tray and the second tray, wherein the first tray and the second tray have: a first operation state in which the first tray is positioned at a paper sheet stacking position; a second operation state in which the paper sheet stacked on the first tray is deliverable to the second tray; and a third operation state in which the first tray that has delivered the paper sheet to the second tray is returned to the paper sheet stacking position.

A counter-ejector comprises: an elevator including a table displaceable in a forward-backward direction parallel to a feeding-out direction; a backward restriction member for restricting a situation where backward edges of corrugated paperboard sheets in a batch are displaced in a direction opposite to the feeding-out direction; table upward-downward movement drive device; a table displacement drive device; and a control device. The control device executes a table downward movement control processing such that the table is displaced backwardly in at least part of a time period when the table is moved downwardly from the hopper part to a table stop position and a time period when the table is stopped at the table stop position, and a table upward movement control processing such that the table is displaced forwardly in a time period when the table is moved upwardly from the table stop position to the hopper part.

A three side trimmer has a trimming unit 1, an accumulating unit 3, a discharge unit 2 and a conveying mechanism 4 conveying trimmed booklets BK to the accumulating unit. The accumulating unit has a shelf 5 movable in a vertical direction, and a drive roller conveyor 7 on the shelf. The accumulating unit, in a mode, delivers the trimmed booklets to the discharge unit at every accumulation of a predetermined number of the trimmed booklets and, in another mode, accumulates the trimmed booklets without delivering.

When sheet products 1 are discharged, the sheet products are collided against shutter bars 5 so as to fall and stack on a feed conveyor 4. Then, each of protrusion bodies 7 and 8 are lowered by a first drive 9 so as to nip the sheet products between the protrusion bodies and the feed conveyor. Then, coming products are successively discharged and stacked on the protrusion bodies. And then, a second drive 12 is operated in conjunction with the feed conveyor so as to feed the sheet products nipped between the protrusion bodies and the feed conveyor 4. The shutter bars 5 are elevated and lowered by a third drive for adjusting the height position thereof.

The invention relates to a station for receiving sheet-form elements and discharging bundles of sheet-form elements for a packaging manufacturing machine, comprising: an arrangement for feeding sheet-form elements successively one after the other (8), a lift table (16), mobile in a vertical direction, comprising several continuous conveyor belts (17) extending in a longitudinal horizontal direction, for receiving the sheet-form elements in bundle form, an output conveyor (14), for discharging the sheet-form elements in bundle form, and a separator (21), mobile in the vertical direction, comprising several reception arms (22) being deployed in the longitudinal horizontal direction, for transiently receiving the sheet-form elements in bundle form, the arms (22) being disposed so as to be able to cross in the vertical direction without interacting with the belts (17) of the table (16).

A sheet stacking apparatus is provided. A conveyor unit performs stacking of sheets discharged from a printing apparatus and conveying of stacked sheets. A detection unit detects whether or not the printing apparatus is currently discharging a sheet. A control unit, so as to secure a stacking space for a sheet discharged from the printing apparatus on the conveyor unit, controls a feeding operation of the conveyor unit correspondingly to a period of time over which the detection unit detected that the printing apparatus is discharging a sheet.

A separator (1) for temporarily receiving sheet elements (9) that are to be transferred from a stacking table (2) to an output conveyor (3) of bundles of sheet elements comprises: a support (10) mounted with the ability to slide in a vertical direction; a drive device (11) for driving the support in the vertical direction; several arms (13) extending in a longitudinal horizontal direction, spaced apart in a transverse direction, at least one arm (13) being mounted with the ability to move in the longitudinal horizontal direction with respect to the support, the movement of the arm modifying its overhanging length with respect to the support (10) on a first side in the longitudinal horizontal direction; a drive system (12) configured to simultaneously move the arm in the longitudinal horizontal direction and to keep another of the arms in its longitudinal position.

The stacker comprises two stacking platforms and a system for conveying corrugated board sheets, configured to discharge the sheets alternatively onto one or the other of the two stacking platforms. A switching device allows for a quick switch of the conveyor system from one to the other of two operating conditions.
