Stripping device
View Patent ↗A stripping device for stripping sheet-shaped objects from a roller includes at least one stripper. The stripper is mounted rotatably about a bearing and includes stripping portion configured to be tapering to a point and a support portion which is different from the stripping portion. The stripping portion and the support portion are arranged relative to each other and the stripper is mounted such that, when the stripper is pressed against the roller with prestressing during operation, the stripper has two mutually spaced apart contact points with the roller, which contact points are defined by the stripping portion and the support portion of the stripper.
1. A stripping device for stripping sheet-shaped objects from a roller, including at least one stripper which includes a stripping portion configured to be tapering to a point and a support portion, wherein the stripping portion and the support portion of the stripper are arranged relative to each other and each are mounted rotatably about a bearing such that, when, during operation with a roller, the stripper is pressed against said roller with prestressing, the stripper has two contact points with the roller which are defined respectively by the stripping portion and the support portion of the stripper;
wherein an angle enclosed in the direction of the roller between a first line which connects the bearing to the one contact point and a second line which connects the bearing to the other contact point amounts to between 60° and 120°.
2. The stripping device according to claim 1 , wherein the stripper is adapted such that, during operation with the roller, the bearing is arranged, with reference to a rotational axis of the roller, radially spaced apart from the roller and between the two contact points.
3. The stripping device according to claim 2 , wherein an angle enclosed in the direction of the roller between a first line which connects the bearing to the one contact point and a second line which connects the bearing to the other contact point amounts to 90°.
4. The stripping device according to claim 1 , wherein the stripping device includes at least two strippers.
5. The stripping device according to claim 1 , wherein the at least one stripper is mounted axially to be rotatable about an axis which is arranged parallel to a rotational axis of the roller, when, during operation with the roller, the stripper is pressed against the roller with prestressing.
6. The stripping device according to claim 5 , wherein the stripping device includes a plurality of strippers which are each rotatably mounted separately.
7. The stripping device according to claim 5 , wherein the at least one stripper is mounted on gimbals.
8. The stripping device according to claim 7 , wherein the stripping device includes a plurality of strippers which are each rotatably mounted separately.
9. The stripping device according to claim 1 , wherein the stripping device includes a carriage on which the at least one stripper is arranged, wherein the carriage is adapted to be movably guided and, during operation with the roller, is adapted to be pressed in the direction of said roller with prestressing.
10. The stripping device according to claim 9 , wherein the stripping device includes a plurality of strippers which are respectively connected to the carriage separately via a spring element.
11. The stripping device according to claim 9 , wherein the at least one stripper is connected to the carriage via a spring element which, during operation with the roller, is adapted to be prestressed against said roller due to the prestressing of the carriage.
12. The stripping device according to claim 11 , wherein the stripping device includes a plurality of strippers which are respectively connected to the carriage separately via a spring element.
13. The stripping device according to claim 1 , wherein the support portion is configured to be rounded in the region in which, during operation with the roller, it is adapted to touch the roller.
14. The stripping device according to claim 1 , wherein the at least one stripper includes an angular portion, wherein the stripping portion is arranged at the end of a first angular arm and the support portion is arranged at the end of a second angular arm, and wherein the bearing of the at least one stripper is arranged in the region in which the two angular arms meet.
15. A system including the at least one roller for transporting sheet-shaped objects and a stripping device according to claim 1 for stripping the sheet-shaped objects from the roller.
16. The system according to claim 15 , wherein the system is a bank-note processing machine.
17. The system according to claim 15 , wherein the roller is a storage roller of a foil winding repository for intermediate storage of sheet-shaped objects.
18. The system according to claim 17 , wherein the system is a bank-note processing machine.
