Image forming apparatus with differential sheet conveying force of discharging rooler pair

An image forming apparatus has an image forming unit that forms an image on a sheet; a discharging roller pair that discharges the sheet, on which the image is formed, onto a stacking portion with a rotation in a first direction, and conveys the sheet to a re-conveying path for conveying the sheet to the image forming unit again with a rotation in a second direction opposite to the first direction; and a skew feed correction member that is provided in the re-conveying path, and contacts against a leading edge of the sheet conveyed by the rotation in the second direction to correct skew feed of the sheet. The sheet conveying force when contacting the leading edge of the sheet against the skew feed correction member is smaller than sheet conveying force of the discharging roller pair when discharging the sheet onto the stacking portion.

DEVICE FOR ORIENTING SECURITY PAPERS

Verfahren und Vorrichtung zum Bearbeiten von Blattgut

In einer Blattgutbearbeitungsvorrichtung, insbesondere Vorrichtung zum Stapeln von Blattgut, wie beispielsweise Banknoten, wird transportiertes Blattgut abgebremst, indem zu einem Zeitpunkt, an dem das Blattgut noch nicht vollständig abgebremst ist, nur auf einen in Transportrichtung rückwärtigen Teil des Blattguts bremsend eingewirkt wird. Aufgrund der beim Bremsvorgang im Blattgut wirkenden Trägheitskräfte führt dies zu einem selbständigen Strecken des Blattguts, wodurch ein Falten und Knittern des Blattguts beim Abbremsen ausgeglichen oder vollständig vermieden wird. In a sheet material processing device, in particular a device for stacking sheet material, such as banknotes, transported sheet material is decelerated by braking at a time when the sheet material is not completely decelerated, only on a rearward in the transport direction of the sheet material. Due to the inertial forces acting in the sheet material during the braking process, this leads to an autonomous stretching of the sheet material, whereby a folding and wrinkling of the sheet material during braking is compensated for or completely avoided.

Nip mechanism and method of operation thereof

A nip mechanism for a substrate transfer system allows the nip mechanism to be actuated such as opened and/or closed by the drive motor for the nip mechanism. As a result, the need to operate the nip mechanism pneumatically, for example, can be avoided. Essentially, the drive motor now performs a dual role, i.e., both driving the nip rollers and also opening and closing the nip mechanism. The nip mechanism comprises a roller separation mechanism and a one-way clutch for engaging the roller separation mechanism when the drive motor is driven in the second direction. In the present implementation, this roller separation mechanism comprises a cam that pushes the first nip roller and the second nip roller away from each other. A cam limiter can be used to prevent over-rotation of this cam.

Drive roll / idler roll nip release mechanism

A drive roll/idler roll nip release mechanism utilizes the motor used for the drive nip, coupled with one-way clutches, to power the nip release as a sheet is handed off to a downstream nip. A drive shaft is coupled to a first one-way clutch in one direction and an idler cam shaft is coupled to a second one-way clutch in the opposite direction. This allows the idler cam shaft to be driven only when the motor is reversed, and the drive shaft to be driven only when the motor is moving forward. The one-way clutch on the drive shaft allows the drive wheels to freewheel when the motor is reversed in order to engage the nip release. Thus, the nip release is activated while the drive nip continues to rotate in the direction of sheet motion.
