摘要:
The present invention relates to a delivery processing apparatus for delivering a sheet after implementing a prescribed sheet processing upon aligning the sheet, comprising an aligning means for aligning a sheet, a conveying means for conveying the sheet to the aligning means and a bundle delivering means disposed on an upstream side of the aligning means in a sheet conveyance direction for delivering a sheet bundle done with a sheet processing. The bundle delivering means is able to choose a conveyable state for conveying the sheet upon nipping the sheet and a non-conveyance state for not conveying the sheet, and wherein when a first sheet among plural sheets to be conveyed to the aligning means by the conveying means is conveyed the conveyable state is chosen whereas when a sheet of the second or later is conveyed the non-conveying state is chosen.

A control system for regulating a dispenser that includes a feeder bowl and a plurality of dispensing paths is disclosed. The control system includes a control unit for controlling a rotation drive for rotating the dispensing paths, a feeder bowl vibration device for vibrating the feeder bowl, and at least one dispensing path vibration device for vibrating the dispensing paths, such that the feeder bowl receives a plurality of items and supply the items uniformly to each of the dispensing paths, and the dispensing paths dispense the items singularly.

A method and a device for aligning sheets. The device includes a first and a second supporting stop for supporting the sheet against gravity in a first non-aligned position of the sheet. The device further includes two alignment stops and an actuator for moving the sheet from the first non-aligned position to a second aligned position. In the second aligned position, a substantially straight edge of the sheet contacts the two alignment stops and the first supporting stop supports the sheet while the second supporting stop does not support the sheet.

In a device for processing documents being transported therethrough along a document feed path, an aligner apparatus comprising: first and second guide walls, each guide wall positioned parallel to the document feed path and facing the other guide wall forming an alley along the document feed path in which the documents are relieved of interdocument forces allowing bottom edge alignment of the documents with the document feed path, the guide walls forming a plurality of openings, each opening in the first guide wall being in alignment with an opening in the second guide wall; and a trap assembly comprising first and second trap levers, each trap lever mounted along the document feed path on a side of the guide wall opposite the document feed path, each trap lever received by one of the plurality of openings in the guide walls and each trap lever opposing the other trap lever and positioned to, when actuated, cause opposing forces on one-another in order to grab the documents as they move along the feed path in the aligner apparatus so as to control the gap between the documents. The trap lever configured with a resilient pad and an air gap to reduce noise when the lever is actuated and contacts the document.

Springs 34 and 35 are located on the back face of a paper cassette, between a movable plate 32 and a bar 31, coupled with a side edge aligner 27. A slot extending in the direction in which a spring load is generated is formed in the movable plate, and a hook portion is formed at the end of the spring in the direction in which the spring is extended or contracted. The length of the slot and the length of the spring end in the direction in which the spring load is generated differ for the individual springs, and correspond to the distance the movable plate is displaced. That is, a size difference is defined for each spring until the spring load is applied. During the insertion of the paper cassette, the movable plate is displaced by the mechanism constituted by the groove cam 41 and the boss 36a, and in accordance with the displacement, different spring loads are multiply applied the paper side edge aligning member via the bar.
摘要:
A guide apparatus for guiding sheets to a sheet-processing machine, in particular a printing machine, and a method of operating the guide apparatus are described. The guide apparatus has at least one guide element which is disposed above a feed table and whose distance from the feed table can be set with the aid of a height-adjusting device. The guide apparatus is distinguished by the fact that the height-adjusting device has a first drive and a second drive, which can be actuated independently of each other.
摘要:
A method of registering a sheet in a duplex copier to alleviate the misalignment between the images copied on the front and back of the same sheet and to compensate for paper cut tolerances. The error angle of skew between a target angle, e.g. 90null, and the trailing edge of the sheet is measured and stored during a first pass. When the same sheet is fed through a second pass, the error angle is retrieved and the target angle is adjusted to compensate for the skew error of the first pass so that any misalignment between front and back images is substantially improved over systems that register images to the sheet without any knowledge of the location of the opposite side image.
摘要:
The holding-down arrangement for holding down a sheet (24) in a sheet-bearing region of a sheet-processing machine, in particular of a folding machine, includes a plurality of blowing devices (19, 21) which, during use, are directed toward a sheet (24) and direct an air jet (20, 22) onto the sheet (24). The holding-down arrangement may be fitted in a sheet-aligning device which is arranged downstream of a sheet infeed and includes a sheet-bearing device (12), on which an incoming sheet (24) comes to rest.

A sheet transport apparatus comprises a predetermined number of transport members 2 disposed in a sheet transport passage 1. At least a part of the transport members 2 is a multi-direction transport member 4 for variably setting the transport direction of a sheet 3 to a plurality of directions. To perform direction switch control of the multi-direction transport member 4, the sheet transport apparatus comprises a transport direction switch unit 8 that can switch the transport direction of the sheet 3 by the multi-direction transport member 4 at a predetermined timing. Alternatively, the sheet transport apparatus comprises a guide member 9 for regulating a side position of the sheet 3.
摘要:
In a method and an apparatus for guiding sheets to a sheet processing machines, provision is made to reduce the adhesion forces between sheets following one another by the trailing edge of the respective first sheet of a sheet stream being lifted. The sheet is lifted using a blowing/suction nozzle or a suction nozzle.
