Abstract

An automatic dispenser for balancing weights including a transport section and a cutting section. The transport section contains a transport roller with a plurality of teeth at its circumferential outer surface generating friction to a belt of balancing weights to transport this belt to the cutting section. Such belt contains a plurality of individual balancing weight segments. The cutting section has an arc shaped belt guide for forming the belt of balancing weights to a curve thus opening at least one gap between neighboring balancing weight segments. The cutting section has a knife movable from a first side of the belt of balancing weights to its second side, to separate the belt of balancing weights at a gap between two individual balancing weight segments.

Claims

1. An automatic dispenser configured to separate balancing weight segments contained in a belt of balancing weights, the dispenser comprising:

a transport section and a cutting section, wherein

the transport section is configured to transport the belt of balancing weights towards the cutting section and includes a transport roller with a circumferential outer surface, wherein the circumferential outer surface has a plurality of teeth dimensioned to generate friction with the belt of balancing weights;

the cutting section has an arc shaped belt guide configured to conform the belt of balancing weights to a curve to open at least one gap between neighboring balancing weight segments,

the cutting section further having a knife configured to move along a cutting path from a first side of the belt of balancing weights to a second side of said belt to cut the belt of balancing weights between two individual balancing weight segments at the at least one gap.

2. The automatic dispenser according to claim 1, further comprising at least one of a counter roller and a counter belt to press the belt of balancing weights against the transport roller to increase said friction.

3. The automatic dispenser according to claim 2, comprising a sensor configured to detect gaps between individual balancing weights of the belt of balancing weights and produce an output signal representing said gaps.

4. The automatic dispenser according to claim 3, wherein the sensor is mounted at a location near the cutting path, and further configured to count a number of balancing weights based on the output signal from the sensor.

5. The automatic dispenser according to claim 1, comprising a sensor configured to detect gaps between individual balancing weights of the belt of balancing weights and produce an output signal representing said gaps.

6. The automatic dispenser according to claim 5, wherein the sensor is mounted at a location near the cutting path.

7. The automatic dispenser according to claim 5, configured to count a number of balancing weights based on the output signal from the sensor.

8. The automatic dispenser according to claim 1, wherein chosen individual balancing weight segments comprise a metal.

9. The automatic dispenser according to claim 8, wherein the metal includes zinc or steel.
