271245000 | Against front-edge aligner interposed into sheet path | 11 |
20080315509 | STACK-LIKE ARRANGEMENT OF FLAT OBJECTS AS WELL AS METHOD AND DEVICE FOR FORMING THE ARRANGEMENT - A stack-like arrangement of printed products with folded edges, in which arrangement the printed products are all arranged with identical orientation, has an increased stability, if it comprises stack sections, within which the folded edges of the printed products indeed lie on top of each other, but wherein the stack sections are arranged displaced in relation to each other, such that the stack sections with folded edges protruding from the arrangement alternate with stack sections with edges opposite the folded edges protruding from the arrangement. | 12-25-2008 |
20090250869 | APPARATUS FOR ALIGNING SHEETS THROUGH THE USE OF STOPS DISPOSED ON A CYLINDER - An apparatus for continuous alignment of sheets which are fed to a processing machine, includes an alignment cylinder on which stops for the sheets are disposed. The stops are pivoted out of the periphery of the alignment cylinder and moved on a translational movement path during an alignment phase. | 10-08-2009 |
20130087968 | SHEET CONVEYING DEVICE AND IMAGE FORMING APPARATUS - A sheet conveying device includes a blocking member having a blocking surface with which a leading end of a sheet that is being conveyed comes into contact for obliquity correction. The blocking member is rotated by being pushed by the sheet against an urging force of a positioning unit that positions the blocking member to be in the standby position. The blocking member is rotatable to be in a sheet-passage-allowing orientation in which the sheet is allowed to pass. When a trailing end of the sheet that is being conveyed has passed the blocking member, the blocking member that is in the sheet-passage-allowing orientation rotates in a same direction as a sheet conveyance direction and is positioned to be in a standby position. | 04-11-2013 |
20130161901 | SHEET TRANSPORT APPARATUS AND IMAGE FORMING APPARATUS - A sheet transport apparatus includes: a transport portion that transports a sheet; a skew correction portion against which a leading edge of the sheet transported by the transport portion abuts for skew correction, the skew correction portion moving to a position where the skew correction portion does not hinder the transport of the sheet after the skew correction; and a plurality of sheet abutting portions that is provided in the skew correction portion and against that the leading edge of the sheet transported by the transport portion abuts, the plurality of sheet abutting portions respectively including a resin member, and an abutting portion which is provided in the resin member and having an abrasion resistance higher than that of the resin member, and against which the leading edge of the transported sheet abuts. | 06-27-2013 |
20130193639 | SKEWED SHEET CORRECTING DEVICE AND IMAGE FORMING APPARATUS - A skewed sheet correcting device includes: first and second shutter members which move to a first position in which the first and second shutter members are pushed to be movable by a leading edge of a sheet, a second position which is disposed further downstream of the sheet conveyance direction than the first position to latch the leading edge of the sheet, and a third position which allows the sheet to pass; and a movement regulating member which, when one of the shutter members does not move to the second position, regulates the other shutter member in the second position, and, when both the first and second shutter members move to the second position, allows the first and second shutter members to move to the third position. | 08-01-2013 |
20140239580 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS - Provided is a sheet conveying apparatus including: a pair of rollers which includes an upper roller and a lower roller and conveys a sheet in a nipping manner; a driving unit which independently drives the upper roller and the lower roller; a conveying unit which is disposed at the upstream of the pair of rollers in the sheet conveying direction and conveys the sheet to the pair of rollers; an overlapping unit which is provided between the pair of rollers and the conveying unit and overlaps a subsequent sheet on a precedent sheet in the conveying direction; and a control unit which controls the driving unit, wherein the control unit controls the driving unit so that: the upper roller and the lower roller are driven before a leading end of the precedent sheet conveyed by the conveying unit reaches the pair of rollers and the driving of the upper roller and the lower roller is stopped before a tail end of the precedent sheet passes the pair of rollers; the pair of rollers is driven again before a leading end of the subsequent sheet conveyed by the conveying unit and overlapped on the precedent sheet nipped by the pair of rollers reaches the pair of rollers and only the upper roller is driven so as to convey the subsequent sheet to the downstream in the conveying direction after the leading end of the subsequent sheet conveyed by the conveying unit reaches the pair of rollers; and the upper roller and the lower roller are driven so as to convey the precedent sheet and the subsequent sheet overlapped on the precedent sheet to the downstream in the conveying direction. | 08-28-2014 |
20150014920 | SUPPLEMENT FEEDER FOR FLAT OBJECTS - A supplement feeder for flat objects, comprising a receiving device with a stack compartment for receiving objects in the form of a stack, and a takeoff device for taking off individual objects from the stack, wherein the stack compartment has a front contact region against which the front edge of the stack rests, and equipped with guiding elements for guiding and shaping the stack, comprising a stack shoe that is arranged at the rear edge of the stack in order to guide the stack in the direction of the front contact region. According to the disclosure, this supplement feeder is equipped with a takeoff device for taking off individual objects from the object stack, and at least one component of the guiding elements, and in particular the stack shoe, is coupled to a knocking unit that transmits a discrete knock impact onto the respective component of the guiding element. Thereby malfunctions in the form of missed takeoffs or multiple takeoffs when taking off objects can be largely avoided. | 01-15-2015 |

20170233203 | SHEET CONVEYING APPARATUS AND IMAGE FORMING APPARATUS | 08-17-2017 |
271246000 | Synchronized with intermittently-active conveyor-couple | 2 |
20140367910 | MOTOR-DRIVEN ALIGNING AND FORWARDING DEVICE FOR APPARATUS FOR PROCESSING PAPER DOCUMENTS AND THE LIKE, IN PARTICULAR BANK CHEQUES - The device ( | 12-18-2014 |
20150035227 | SHEET CONVEYING UNIT AND IMAGE FORMING APPARATUS - A sheet conveying unit includes a shutter portion including an abutting portion correcting a skew of a sheet by abutting against a front end of the sheet at a standby position upstream in a sheet conveying direction of a nip of the conveying roller pair, and a bias portion biasing the shutter portion such that the abutting portion is positioned at the standby position. The bias portion is configured such that a rate of increase of a bias force applied from the bias portion to the shutter portion during when the abutting portion is turned from the standby position to a nip position where the sheet is nipped by the conveying roller pair is smaller than a rate of increase of the bias force during when the abutting portion turns by being pushed by the sheet nipped by the conveying roller pair from the nip position. | 02-05-2015 |
