A driving apparatus includes an endless belt, a belt roller which engages the endless belt, a steering member and an adjustment member. The belt roller has a rotation shaft. The steering member contacts the endless belt at the inner side of the endless belt. The adjustment member is supported rotatably. The adjustment member receives a force in response to the endless belt moving in a longitudinal direction of the rotation shaft of the belt roller, and generates a pressing force that tilts the steering member via a rotational movement of the adjustment member.

An apparatus and a corresponding method for singling value documents, in particular banknotes, includes a support means and a conveyor belt for picking a single value document from a stack of value documents lying on the support means. The singling device has a positioning device by which at least a portion of the conveyor belt can be moved back and forth relative to the support means between a first position and a second position. In the first position the conveyor belt cannot touch the stack lying on the support means. In the second position the conveyor belt can touch the lowermost value document of a stack lying on the support means and pick the former from the stack at least partially.

A method and apparatus are disclosed for transporting at least one item of media. The apparatus includes at least one guide member providing a first guide surface that guides at least one item of media as the item is transported, at least one elongate slit in the guide surface and at least one belt member each extending along a respective slit and comprising a first belt portion that extends outwardly from the slit beyond the guide surface and a further belt portion that undercuts a region of the guide surface.

An apparatus for conveying sheets through a printing machine allows driving a sheet transport belt obliquely with respect to the conveying direction with a simple configuration. At least one deflection roller has a conical running surface (with or without a crowned face). At least one belt travels over deflection rollers, including the at least one deflection roller, and the belt running direction is oblique with respect to the sheet transport direction.

A positioning assembly is provided with an endless loop conveyor belt for transporting an object and a first and second roller (12) arranged inside the endless loop. A first mounting part connected to a first end of the first roller (12) and a second mounting part connected to a second end of the first roller (12) are independently movable in a length direction of the conveyor with respect to the frame (15). An actuator system is provided which includes a first lateral actuator (61) arranged to move at least a part of the first roller (12) in a direction parallel to the rotational axes (106) of the first roller (12). The first roller (12) is longitudinally divided into at least two longitudinal segments. The first lateral actuator (61) moves at least one of the longitudinal segments parallel to the rotational axis (106) of the first roller (12).

A protrusion (13a) and a protrusion (13b) are formed a predetermined distance apart in the direction of a shaft in the outer circumferential surface of the roller main body (11). The cross sections of the protrusion (13a) and the protrusion (13b) are shaped such that a center portion of the roller main body (11) in the direction of the shaft is a boundary (14), and that on the left side of the boundary (14), a vertex (131a) is displaced to the left side from the perpendicular bisector (133a) of an opposite side (132a) whereas on the right side of the boundary (14), a vertex (131b) is displaced to the right side from the perpendicular bisector (133b) of an opposite side (132b). In this way, in a metallic movement roller that moves a strung endless belt, the winding movement and the like of the belt can be prevented, and the belt can be intentionally moved in a specific direction.

A belt drive device includes a plurality of rollers and an endless belt stretched around the rollers, and configured to drive the endless belt by rotating the rollers. The belt drive device further includes a roller-shaft shifting member that shifts at least one end of a shaft of at least one roller of the above described rollers in accordance with the movement of the endless belt in the axial direction of the roller.

A conveying belt mechanism for an automatic document feeder, for conveying a document placed on a document bearing plate to a document exposure position on a transparent platen. The conveying belt mechanism includes a driving roller and a driven roller disposed above the transparent platen, with a predetermined spacing provided between the two rollers in a document feeding direction, an endless conveying belt looped over the driving roller and the driven roller, pressing rollers disposed between the driving roller and the driven roller for pressing the endless conveying belt against the transparent platen, and belt guides mounted at both ends of the driven roller. Each belt guide includes a boss portion mounted on a rotating shaft of the driven roller so as to be capable of relative rotation, a detachment-preventing portion which protrudes from the boss portion diametrically beyond an outer peripheral surface of the driven roller and which has a front end bent inwardly, and a rotation stopping portion provided in the boss portion, the rotation stopping portion being engaged with a rotation restraining member.
摘要:
In some examples, a sheet-processing machine includes a transport unit for transporting sheets. The transport unit includes a feed roller configured as an infeed roller and a feed roller configured as a diverting roller, which define a transport plane of sheets. At least two further feed rollers of the transport unit are arranged outside the transport plane. At least one feed roller of the at least two further feed rollers is configured as a pivoting roller that pivots and/or that can be pivoted about a pivot axis. The pivot axis of the pivoting roller is an axis that is normal of an axis of rotation of the pivoting roller, and the pivoting roller is configured to automatically pivot about the pivot axis.
