Abstract

The invention relates to a self-adjusting processing system for sheet material. A self-adjusting processing system for sheet material comprises a guiding device for sheet material having a main transport and a redirecting device for sheet material having a branch transport in association with the main transport to redirect the sheet material. The redirecting device further has fixed rollers adopted to interact with the branch transport and floating members, the fixed rollers and the floating members are positioned at opposite sides of the branch transport and each floating member is adopted to be aligned with appropriate fixed roller. The redirecting device further comprises fixing means for fixing the floating members'"'"' position relative to the fixed rollers, releasing means for releasing the floating members'"'"' position relative to the fixed rollers, and a first actuating means for moving the floating members towards the fixed rollers till the floating members engage the fixed rollers and backwards from the fixed rollers. Also provided is a method of processing of a piece of sheet material with the self-adjusting processing device of the present invention. The processing system and the method can be used with any sheet materials, advantageously with banknotes.

Claims

1. A self-adjusting processing system for sheet material, the system comprising a guiding device for sheet material having a main transport and a redirecting device for sheet material having a branch transport in association with the main transport to redirect the sheet material, the redirecting device further having fixed rollers adopted to interact with the branch transport and floating members, wherein the fixed rollers and the floating members are positioned at opposite sides of the branch transport and each floating member is adopted to be aligned with appropriate fixed roller,

characterizing in that the redirecting device further comprises fixing means for fixing the floating members'"'"' position relative to the fixed rollers, releasing means for releasing the floating members'"'"' position relative to the fixed rollers, and a first actuating means for moving the floating members towards the fixed rollers till the floating members engage the fixed rollers and backwards from the fixed rollers.

2. The processing system of claim 1, wherein the fixing means comprises a friction brake adopted to interact with a spring, the releasing means comprises a striker and a pusher and the first actuating means comprises a first actuator.

3. The processing system of claim 1, wherein the fixing means comprises a friction brake adopted to interact with a spring, the first actuating means comprises a first actuator and the releasing means comprises a second actuator.

4. The processing system of claim 1, wherein the fixing means and the releasing means comprise an electromagnetic friction brake.

5. The processing system of claim 1, wherein the floating members comprise floating rollers.

6. The processing system of claim 1, wherein the floating members comprise floating pads.

7. The processing system of claim 1, wherein the guiding device further comprises at least two guiding rollers connected to the first actuating means, the first actuating means being adopted to move the guiding rollers towards the main transport till the engagement with the main transport and backwards from the main transport, stabilization means configured to stabilize the relative positions of the guiding rollers when they are being moved away from the main transport, and at least two support rollers, wherein the guiding rollers and the support rollers are positioned at opposite sides of the main transport.

8. The processing device of claim 7, wherein the stabilization means comprises first suspensions each connecting two adjacent guiding rollers and at least one second suspension connected to the first suspensions substantially directly or at the proximity of common mass centers of every first suspension and their corresponding guiding rollers, the first suspensions and the second suspension having rotational joints substantially at their mass centers, wherein the first actuating means are connected to the guiding rollers directly or at the proximity of a common mass center of the second suspension and the first suspensions with their corresponding guiding rollers.

9. A method of processing of a piece of sheet material with the self-adjusting processing device of claim 7, the method comprising:

locating a piece of sheet material on the moving main transport of the guiding device to transport the sheet material to the branch transport of the redirecting device;

clamping the piece of sheet material between the guiding rollers and support roller;

moving the guiding rollers away from the piece of sheet material using the first actuating means and stabilization means and clamping the piece of sheet material between the floating members and the fixed rollers using the first actuating means to transport the piece of sheet material to the branch transport of the redirecting device;

releasing the floating members'"'"' position using the releasing means;

fixing the floating members'"'"' position using the fixing means after the floating members are realigned fully or at least partially in an accumulative way with the fixed rollers;

moving the floating members away from the fixed rollers using the first actuating means; and

engaging the guiding rollers with the main transport to align the guiding rollers with the support rollers.

10. The method of processing of a piece of sheet material according to claim 9, wherein before locating a piece of sheet material on the moving main transport of the guiding device to transport the sheet material to the branch transport of the redirecting device the method further comprises engaging the floating members with the fixed rollers, releasing the floating members'"'"' position to fully align the floating members with the fixed rollers and fixing the floating members'"'"' position using the fixing means;

said releasing and fixing actions not performed when processing the piece of sheet material.
