A banknote handling apparatus 100 includes a bundling stacker 4 configured to pile and stack banknotes B. The bundling stacker 4 includes a positioning unit 47 configured to face a first edge b1, which is one of edges of the banknote B stacked, and place the first edge at a predetermined alignment position P; and a pushing unit 49 configured to push a third edge b3, which is another one of the edges of the banknotes B opposite to the first edge b1, to bring the first edge b1 into contact with the positioning unit 47. The positioning unit 47 is configured to be replaceable such that replacement of the positioning unit 47 changes the alignment position P.
摘要:
In a post-processing device (sheet discharge device) (60), a pile thickness calculating section (613) calculates, from a type and the number of paper sheets discharged through a sheet output port (606), a thickness of a pile, at its leading end, of sets (P1) of paper sheets on a sheet output tray (piling section) (623), calculates a thickness of the pile at its trailing end from an amount of movement of a lifting section (605), and calculates an angle of inclination of the uppermost paper sheet (P) in the pile from the thicknesses of the pile at its leading and trailing ends, a height of inclination of the sheet output tray (623), and a length of the paper sheets (P). A control section (10) controls a sheet discharge section (652, 607, 602, 620) to change a manner of discharging a subsequent paper sheet set (P1) according to the calculated angle of inclination.
摘要:
An image-forming apparatus has a limitation pad 31c and a retard roller 34, which separately feed recording paper P on an elevation tray 31 in an MPT cover 30 by bringing the recording paper P against an outer peripheral surface 33a of the feeding roller 33. In this image-forming apparatus (paper feeder), when the feeding roller is stopped by passing recording paper to be separately fed to a pair of relay transport rollers, the elevation tray is lowered before stoppage of the feeding roller, thereby separating an extremity of the recording paper from the outer peripheral surface of the feeding roller.

The present invention improves the quality of a package (7) by preventing wrinkles in a yarn winding device which forms the package (7) by winding a supplied yarn (4) around a winding tube (6) while applying a tension to the yarn (4) by a tensioning device (30) and traversing the yarn (4) by a traversing device (5). Particularly, in precision winding with a fixed number of winds, in synchronism with an increase in diameter of a yarn layer (7) and a change in a traverse angle (θ), the tension to be applied by the tensioning device (30) is changed. In detail, according to reduction in the traverse angle (θ) calculated by traverse angle calculating means (75), tensioning control means (77) controls to reduce the tension to be applied.

摘要:
Die Erfindung betrifft ein Verfahren zur Eichung oder Nacheichung eines Umrechnungsfaktors (Web-Encoder-Resolution), mit dem zur Bestimmung einer von einem Bedruckstoff in einer Druckmaschine, insbesondere einer elektrophotografisch arbeitende Druckmaschine, zurückgelegten Wegstrecke Takte eines Drehwinkelgebers (7) (Web-Encoder), welcher den Vortrieb des Transportbandes (2), vorzugsweise die Drehung eines rotierenden Antriebselementes (5) für das Transportband (2), signalisiert, in ein Längen maß umgerechnet werden. Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der genannten Gattung aufzuzeigen, das mit hinreichender Genauigkeit zeitökonomischer und vorzugsweise auch automatisiert durchführbar ist. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die bei der Bewegung über das Maß seiner Längserstreckurig eines in seiner Längserstreckung bekannten oder anderweitig gemessenen Abschnittes des Transportbandes (2) anfallende Anzahl Drehwinkelgebertakte ermittelt und zu der bekannten Längserstreckung ins Verhältnis gesetzt werden.
摘要:
Apparatus for reducing peak tensions and tearing in perforated sheet (40) being drawn along a flow path from a stack (S) into a finishing machine (F) is comprised of a drag unit (22), for retarding motion of the sheet; an assist unit (20) for urging the sheet along the flow path; and, a dancer unit (24) for changing the length of the flow path. The assist unit comprises a pair of constant speed rollers (42, 44) supported by mounting blocks (40). The orientation of the assist unit is changed by rotating the mounting blocks. The roller (30) of the dancer unit is spring biased against the sheet.
摘要:
The invention relates to devices for aligning sheets (1), which are overlapped with an offset and supplied to the device by a stream feeder and which can be transferred to a device (63) that is located downstream, after alignment of the front edge and one lateral edge of the sheets. At least part of a sheet can be brought to rest on the periphery of an alignment cylinder (62), which is used to align the front edge of the sheet by means of front lay marks located on the periphery of said cylinder. At least one recess is provided on the periphery of the alignment cylinder, which, by the application of a negative pressure to said recess allows at least part of the sheet to be fixed by friction on the periphery of the alignment cylinder, in such a way that in the contact zone, drive forces from said cylinder can be transferred by friction to the sheet. A measuring device (64) determines the offset of a lateral edge of the sheet in relation to a predetermined set alignment. A transversal displacement device is used to align a lateral edge of the sheet in accordance with the measurement result of the measuring device. The acceleration and/or speed and/or angle of rotation of the drive motor for driving the rotation of the alignment cylinder can be controlled or adjusted according to predetermined laws of motion, in particular in accordance with the angle of rotation of the alignment cylinder.
摘要:
An apparatus for unwinding a strip (2) from a coil (3) and feeding the strip (2) to an assembly (4) for processing the strip (2) has a rotatable table (10) for supporting the coil (3) and a drive unit (12, 13) for rotating the coil-supporting table (10). The drive unit (12, 13) has a driving gear (12) which meshes with a toothed periphery of a gear ring (11) mounted on the table (10) and which is driven by a motor (13). Further, the appparatus has a device (20, 21) for guiding and tensioning the strip (2) between the coil-supporting table (10) and the processing assembly (4). This device (20, 21) includes a pivotable arm (20) having a strip-guiding unit (21) which is movable towards and away from the coil-supporting table (10) by pivoting of the arm (20), and means (26) for controlling the movement of the arm (20) and thereby the movement of the strip-guiding unit (21) in accordance with the strip-feeding rate and the rotational speed of the coil-supporting table (10).
