Definitions

• the invention relates to a method for separating loose batt material, in particular bank notes, in which the sheet material is provided in an input compartment in the form of a stack in a defined position for vertical tracking of the sheet material to a separator. The sheet material is moved vertically from the tracking position into a sealing position and separated within the input compartment.

• a method or a device of the above. Art is known for example from EP 0 135 395 B1.
• a stack of sheet goods is transported to the separating device by a stack transport system when the last sheet of the previous stack is separated. As soon as the last sheet of a stack has been separated, that becomes
• Transport system activated to feed another stack. As soon as the stack of sheet material lies with its front edge in a defined position for vertical tracking of the sheet material on a stacking table, the sealing process is started.
• the known method has the disadvantage that the provision of the next stack of sheets to be separated can only be started on the stacking table when the last sheet of the previous stack has left the separating device. As a result, the separation must be interrupted in order to prepare a new stack, which is particularly disadvantageous when separating large quantities.
• this solution is not satisfactory, however, because it is caused by the rapid transport of the stack of sheets can shift individual sheets, which can lead to problems with the positioning and thus with the separation of the stack of sheets.
• the invention has for its object to propose a method for separating loose sheet material, which enables a higher throughput with a trouble-free process in a separating device.
• the basic idea of the invention is that the next batch to be separated is provided in the input compartment of the separator in a defined position, while the previous stack is still being separated in the separator. This will make the
• the stack of sheet material already being processed in the separator can be combined with the next stack to be separated in the separating device, as a result of which a continuous flow of the sheet material is obtained within the input compartment of the separator.
• This has the particular advantage that the separation process can be carried out without interruption due to the continuous tracking of the sheet material within the separator.
• the throughput rate can be further improved, which makes the invention particularly suitable for high-speed sorting machines in which the sheet material is fed in loosely.
• the invention can be used to check freshly printed banknotes or also to check the condition of used banknotes, which are loosely provided in the input compartments of the separator.
• Several stacks of freshly printed or used banknotes can thus be combined to form a billing unit, which are then distributed over several input compartments.
• the last sheet of the accounting unit can, for example, be automatically recognized by a reflex light barrier of the separator.
• the input compartments are designed to be transportable and can be filled with sheet material at a loading position and transported to one or more separators.
• a corresponding transport system is provided for transporting the input compartments, which can include one or more transport routes which can be connected to one another.
• Several input compartments can be arranged one behind the other in the transport route, with the transport route having a storage function.
