Device and method for separating value documents, in particular banknotes, and value document processing system

A device for separating value documents, comprising:

• a receiving device which is designed to receive a stack of value documents,
• a rotatable separating element which is designed to act temporarily on a value document of the stack each time and to withdraw the value document from the stack, and
• a drive device which is designed to rotate the separating element,
• wherein a control device which is designed to control the drive device such that a rotational speed of rotational movement the separating element is made to perform by the drive device is changed temporarily, during one revolution of the separating element,
• wherein the control device is designed to control the drive device such that the separating element
• rotates at a first rotational speed while the separating element is acting on the value document of the stack and withdrawing the value document from the stack, and,
• during one revolution in each case, temporarily rotates at a second rotational speed, which is faster or slower than the first rotational speed,
• wherein the separating element is designed to feed the value documents withdrawn from the stack each time to a transport device arranged downstream of the separating device and configured to transport the value documents at a transport speed, and
• wherein the first rotational speed is selected such that a track speed of the separating element, while the separating element is acting on the value document of the stack and withdrawing the value document from the stack, corresponds to the transport speed.
