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 machine for the formation of numbered packs of interleaved sheets of paper (6), includes a pair of counter-rotating motor-driven folding rollers (2, 3), an interference surface (11) mobile with a to-and-fro motion between a position (P1) of non-interference and a position (P2) of interference, and a mechanism (36) of cyclic movement of the surface (11) including at least one supporting crank (13) oscillating with respect to the carriage (26) and articulated to a first axis (15) of rotation of the surface, and a first motor-driven connecting rod (19) kinematically connected to the surface (11) to bestow the to-and-fro motion thereon.

A sheet stacking system includes a conveyor for carrying sheets from a conveyor intake end to a conveyor discharge end and a hopper at the discharge end for receiving the sheets and guiding them as they fall in a cascade path onto a platform. The hopper has a backstop facing the discharge end of the conveyor and a first accumulator that includes a carrier and a support extending from the carrier through the backstop. The support is configured to rotate from a retracted position to an extended position relative to the backstop, and the carrier is movable linearly and vertically relative to the backstop with the support in the extended position from a raised location with the support outside the cascade path to a lowered location with the support in the cascade path.

The sheet stacker includes a sheet conveyor arrangement, configured for feeding a plurality of sheets and having a sheet discharge end, and a stacking bay. In the stacking bay sheets delivered by the sheet conveyor arrangement are formed into stacks. A stack conveyor is provided in the stacking bay and is movable in a conveyor direction parallel to a sheet feeding direction, according to which the sheets are fed from the sheet discharge end onto the stack conveyor. The sheet discharge end is configured and controlled such that it is gradually lifted during sheet stacking, in order to accommodate a growing stack of sheets being formed on the stack conveyor. A stop plate is positioned in the stacking bay above the stack conveyor and in front of the sheet discharge end of the sheet conveyor arrangement. The stop plate is configured and controlled to be gradually lifted from the stack conveyor as the sheet stack grows, to be withdrawn upon completion of the stack thus allowing removal of the stack in an evacuation direction substantially parallel to the conveyor direction, and to be lowered towards the stack conveyor again.

A sheet stacker includes a sheet conveyor arrangement and a stacker platform. The sheets are fed in a sheet feeding direction on the stacker platform, to form stacks of sheets thereon. The stacker platform supports a stack conveyor configured and controlled to move in a conveyor direction to move the stack under formation such that sequentially piled up jobs are placed in an approximately centered position one with respect to the other according to the sheet feeding direction.

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.

A apparatus includes a storage mechanism that includes a plurality of storage spaces where paper sheets are stored and continuously feeds out the storage spaces toward one direction while creating the storage spaces one by one, an alignment mechanism that carries banknotes into the storage spaces in the order that the storage mechanism feeds out the storage spaces, and a controller that controls the alignment mechanism and the storage mechanism.

An image rendering apparatus and method of operating a center tray of an image rendering apparatus. The image rendering apparatus includes a cavity, and a center tray having a home position located within the cavity and a retrieval position located outside the cavity. The image rendering apparatus further includes a retraction mechanism that is attached to the center tray and an interior wall of the cavity. The retraction mechanism is configured to allow for the extension of the center tray from the home position to the retrieval position, and from the retrieval position to the home position.

An automated sheets processing system has a vertical stacks accumulating region (SAR) into which sheets are uninterruptedly fed to build vertical stacks for pre-specified loads including completed loads and newly building nascent loads. A tiltable Stacking Deck has a downstream discharge end from which the sheets can be fed at different elevational levels into the stacks accumulating region. A nascent sheets accumulator system has a plurality of support surfaces that are retractably interjectable into the stacks accumulating region for defining a separation gap between the top of a completed load and the bottommost sheet of a nascent new load. At least one of the support surfaces is retractably interjectable in an upstream direction into the stacks accumulating region while at least two others of the support surfaces are retractably interjectable in a downstream direction into the stacks accumulating region. One of the support surfaces has an anti-scuff feature.

A processing apparatus comprises: a conveyance part for conveying a sheet; a processing part including a processing member that is installed in a manner of being movable in an intersecting direction of intersecting with a conveyance direction of the conveyance part and that performs predetermined processing at a predetermined position of the sheet under conveyance; a stacker part for accumulating processing articles obtained by the processing of the processing part; and a control part for controlling the stacker part such as to sort a predetermined amount of precedently ejected ones of the processing articles from the subsequent ones of the processing articles among the processing articles ejected to the stacker part by the conveyance part.
