Abstract:
A document inverting-and-transporting apparatus includes a transport path, an inversion-and-transport path, a document transporting unit, a closed portion, a document length detecting unit, a comparing unit, a controlling unit. The transport path includes a first route along which the document is transported from a feeding start position to a transport direction changing position; a joining position; and a reading position. The inversion-and-transport path includes a second route along which the document is transported from the transport direction changing position to the reading position via the joining position. The closed portion constitutes a part of the inversion-and-transport path. The comparing unit compares a detected length of the document with a predetermined length larger than a length of the closed portion. The controlling unit determines whether the document is to be transported to the inversion-and-transport path, based on a result of the comparison.
Abstract:
An apparatus for receiving, inverting and returning sheets from and to a printer for large-sized paper, said printer being adapted to be automatically fed a web of paper from a supply of paper through an inlet (6), defined by a portion of a paper-supporting plate (7), where said printer further is adapted to print and cut sheets of said web of paper and to guide the printed sheet out thereof through a separate outlet (13), where the apparatus is adapted to receive the just printed and cut sheets from said outlet and to return said sheets to the printer in the inverted state. The apparatus comprises a rotatable first guide means (14), which in one position guides the sheet into the apparatus and in a second position guides said sheet past the apparatus. The apparatus comprises furthermore a first driving roller means (36) and a second guide means (21) pivotally arranged relative to said roller means, where the second guide means (21) in a first position guides the sheet advanced to the apparatus round the first roller means (36) during the initial movement of the sheet into the apparatus, and where said second guide means (21) in a second position presses said sheet into a driving engagement with the first driving roller means (36) in such a manner that said first driving roller means (36) takes over the driving of the sheet both during the remaining movement of said sheet inside the apparatus as well as during the movement of said sheet out of said apparatus again and into the printer through the inlet (7) of said printer while the direction of rotation is inverted. The apparatus comprises also a second driving roller means (46) adapted to engage the portion of the web of paper (60) being left on the paper-supporting plate (7) after the sheet has been cut off and to pull said portion temporarily backwards in such a manner towards the paper supply (61) while the sheet is being inverted that said sheet can be guided into the printer without colliding with the web of paper.
Abstract:
An apparatus and method for changing the orientation, height and direction of envelopes conveyed in an inserter system. The invention reorienting horizontally transported envelopes to a vertical position. The envelopes then being transported around a turning arrangement comprised of a length of driven belt urged against a large diameter idler wheel. A turning guide serves to aid the envelopes through the turning arrangement. A ramp module comprised of nips having toroidal outer circumferences elevate the vertical envelopes. The envelopes finally are turned 180 degrees to be sorted into sorting bins. The overall arrangement of the invention results in an output sub-system of an inserter system with a shortened footprint and ergonomically desirable layout. Also, features of the invention provide that envelopes avoid damage and jamming and that recently closed envelope flaps do not inadvertently open.
Abstract:
An anti-inertia stacker for stacking products and especially suited for products which are prone to dislodgment on or from a substrate during processing movement is provided. The anti-inertia stacker comprises a traveling pallet which is mounted for movement. The traveling pallet receives a product or product laden substrate from a conveyor while traveling at substantially the same speed as the conveyor. The traveling pallet includes a moveable conveying surface. The conveying surface, moving in the direction opposite to the direction of travel of the product or product laden substrate, decelerates the received item. The product or product laden substrate can then be stacked.
Abstract:
A bottom sheet inserter is described in which a conveyor is provided on a frame that defines a path for a load. The conveyor is operable to move the load in a forward direction along the path. A bottom sheet insertion station is situated between first and second conveyor flights which support and move a load in a forward direction. A bottom sheet feeder is operable to feed a bottom sheet through the bottom sheet insertion station and under the load as the load moves from the first flight and onto the second flight.
Abstract:
A feeding direction altering device for documents comprising a receiving device having a bottom plate and a top plate that form a gap therebetween to receive a document to be fed thereinto; a first transmitting mechanism provided on the receiving device for transmitting the document along a Y direction; a positioning device for positioning the document; and a second transmitting mechanism for transmitting the document along an X direction and out from the feeding direction altering device; wherein the Y direction and the X direction are substantially perpendicular to each other.
Abstract:
An apparatus that can rotate a sheet 180null or invert the sheet, if required, includes a horizontal cylinder. The apparatus includes a horizontal cylinder. A front image output sheet wraps around the horizontal cylinder (turning counterclockwise), entering the cylinder from the bottom. The cylinder then rotates 180null with the wrapped sheet. Continued counter-clockwise rotation of the cylinder will now unwrap the sheet from the cylinder and drive it away from the cylinder. In order to accomplish inversion, a deflector is raised in front of the cylinder. A sheet is directed over the top of the cylinder by the deflector as the cylinder turns clockwise. The sheet wraps around the cylinder and thereafter, the cylinder is rotated counter-clockwise resulting in the sheet exiting the cylinder at the bottom after having been inverted.
Abstract:
In a sheet-processing apparatus, banknotes are separated by a separator (10) and fed to a depositing arrangement (18) via a sensor and transporting unit (8). Depositing takes place in different depositing compartments in accordance with depositing criteria which are determined by certain features of the banknotes (BN) being sensed. The individual depositing compartments (30, 32, 34) of the depositing arrangement (18) are assigned stacker wheels (20, 22, 24), which have stacker fingers which, in pairs, define a sheet compartment between them. The banknotes are introduced into the sheet compartments and are then deposited in the associated depositing compartment by the stacker fingers. In order to prevent fed banknotes from coming into contact with stacker-finger tips and then not being deposited correctly, the rotational speed (including phase) of the stacker wheels (20, 22, 24) is synchronized with the operating frequency of the separator (10) such that the individual banknotes enter centrally into the sheet compartments of the stacker wheels.
Abstract:
A device for reversing the direction of motion of a paper sheet has a passage for guiding the paper sheet inside and includes a plurality of rollers each having a specified function. A first roller serves as a driver roller, its rotation causing the paper sheet to be transported into and out of the passage. A second roller is for contacting and rotating with the first roller and thereby transporting the paper sheet in the first direction into the passage. A third roller is disposed on the opposite side of the first roller from the second roller and serves to transport the paper sheet in the second direction out of the passage by contacting and rotating with the first roller. A fourth roller is another driver roller and is disposed in the passage. It allows the front edge of the paper sheet to pass by when it is transported in the first direction by means of the first and second rollers. When the paper sheet has passed between the first and second rollers and its back edge has been disengaged from them, a guiding member pushes and guides the back edge of the paper sheet towards the third roller and the four roller rotates so as to transport the paper sheet in the second direction out of the device.
