摘要:
A sheet inverting and stacking system in which a rotatable sheet stacking unit (52) receives the lead edge area of an incoming sheet (11) and then rotates and releases that lead edge area of the sheet at a lead edge registration position for stacking the sheet inverted in a set of stacked sheets at least partially on a stacking tray (32) in a stacking area; with a movable sheet registration system (16) providing plural sheet lead edge registration positions (12, 14); a sheet set fastening system (20) (stapler) for fastening the stacked sets; a first registration position (12) for set fastening in which the sheet stacking area extends into the sheet set fastening system and a second registration position (14) in which the sheet stacking is in front of the sheet fastening system, to provide two different initial sheet leading edge stacking positions and one final stacking position. The rotatable sheet stacking unit (52) is interdigitating with the movable registration system to carry the sheet lead edge directly into the first or second registration positions and also into the sheet fastening system in the first registration position. The stapler (20) is under and at least partially inside of the rotatable sheet stacking unit, and the rotatable sheet stacking unit slots (54) carry the lead edge area of the incoming sheet directly up to the first registration position and into the stapler before releasing it. The sheet lead edge retaining slots have low force retaining spring members (50) which lightly hold the lead edge of the sheet against one side of the slot. A bail system (60) is actuated in coordination with rotation of the rotatable sheet stacking unit (52) to operate a tamper arm (62) which moves downwardly the lead edge area of a sheet (11) being released at the registration position.

A printer (10) for printing images from a photoconductor (28) onto copy sheets (60) and tab stock (71) includes stalled roller registration nip (91,92) in a copy sheet path. The printer has a special materials tray (72) and a sheet feeder (73-75) for feeding tab stock from the tray to the paper path. Dual sensors (81,82) connected to an AND gate (85) are positioned in line across the paper path downstream of the special materials feeder (72) to sense the feeding of tab stock (71) and send a signal to a controller (100) which stops the sheer feed. Once a signal is received by the controller that an image is in a particular position on the photoconductor (28), the sheet feeder is started again by the controller (100) with the roller registration nip (91,92) operating at process speed as well. When standard copy sheets are fed from conventional paper trays, the stalled roller registration nip (91,92) operates to stall and register copy the sheets before they are fed to the U photoconductor.
摘要:
A transition module adapted to accept copy sheet input from an input feeder short edge first and feed the copy sheets long edge first to the main paper path of a processing apparatus. The transition module includes a belt-on-belt transport (65,67) to move copy sheets into the transition module from, for example, the output of a third party feeder. The sheets are fed to the belt-on-belt transport (65,67) and driven against a registration edge (63). The belts are continuously running and provide enough drive force to move the sheets to the registration edge (63), but not enough to overdrive the sheets or cause buckling. Once each sheet is registered, double 'D' rolls (70-73) are activated for one revolution to pull the sheet from the belts (65,67) and feed it to an exit nip located downstream from the 'D' rolls (70-73).
摘要:
An on-line printed sheets output handling system (10) for printed sheets sequentially output by a reproduction system is described herein, in which the printed sheets are registered in neatly superposed sets which are optionally fastened together by finishing apparatus (14, 18). At least a portion (18) of the finishing apparatus is laterally repositionable to provide variable set finishing. A lateral registration system (20) for the printed sheets output is repositionable with the portion of the finishing apparatus (18), and has a sheet registration member (22) engaging and laterally registering the printed sheets to selectable variable lateral sheet registration positions. A registration disengagement system (24) is also provided for moving the sheet registration member (22) out of registration engagement with the sheets after a set of sheets has been laterally compiled and before the finishing apparatus (18) is laterally repositioned. The finishing apparatus (14, 18) comprises two staplers, one stapler (14) being fixed, and the other stapler (18) being laterally repositionable and carries the sheet registration member (22) of the lateral registration system (20).
摘要:
A system and method for manually removably locking a paper handling (20) module to a reproduction apparatus (10) with greatly reduced manual force, wherein the reproduction apparatus and the paper handling module have respective sheet feed openings which are operatively aligned for sheet feeding therebetween when the module (20) is so locked to the reproduction apparatus in a locking position, and wherein the paper handling module has a weight which is undesirable for manual lifting into the locking position. The module (20) is supported on an integral module transporting system (26-33) to be freely movable in any horizontal direction into an initial docking position closely adjacent to the reproduction apparatus (10). Then, slightly vertically lifting at least one side of the module (20) with only a small vertical manual lifting force while most of the weight of the module is lifted with an automatic weight lifting system (34, 35), moving the module towards the locking position, and then removing the small vertical manual lifting force from the module, to drop and lock the module to the reproduction apparatus (10). The automatic weight lifting may be provided by vertically movably spring (34) loading at least one side of the module on the module transporting system (26-33).
