Abstract

The invention proposes an insertion device for coins for transferring said coins to a coin tester or to a coin-operated machine, having an insertion slot and having a coin outlet, between which is arranged a rotatable drum having a receiving region for receiving a coin, wherein in a receiving position, the receiving region is accessible to a coin which can be inserted through the insertion slot, and the insertion slot can be closed off by means of rotation of the drum. The drum having the receiving region is covered by a flap which can be opened in a controlled fashion in an ejection position for ejecting foreign material.

Claims

1. An insertion device for coins for transferring into a coin tester or a coin-operated machine, the insertion device comprising:

an insertion slot;

a coin outlet; and

a rotatable drum which is disposed between the insertion slot and the coin outlet, the rotatable drum including a receiving region for receiving a coin, whereby the receiving region is operable to receive the coin introduced through the insertion slot in a receiving position, and wherein the insertion slot is closable by rotation of the rotatable drum,

wherein the rotatable drum with the receiving region is covered by a flap configured to be opened in a controlled manner for discharging a foreign material in an ejection position.

2. The insertion device according to claim 1 comprising a control unit, wherein the control unit is connected to a motor for actuation of the rotatable drum, the control unit operable to control of an insertion and transfer process of the coin.

3. The insertion device according to claim 1, wherein the flap is in operational connection with an opening mechanism for a forced control.

4. The insertion device according to claim 3, wherein the opening mechanism has at least one curved path provided on the rotatable drum and a lever arrangement cooperating with the flap.

5. The insertion device according to claim 2, wherein the control unit is operable to actuate the rotatable drum via the motor such that a multiple change in the direction of rotation takes place and the flap opens several times.

6. The insertion device according to claim 2, wherein the control unit is operable to control the motor and hence the rotatable drum for opening the flap as a function of the motor current and/or sensor signals which indicates locking of the rotatable drum and/or the presence of foreign objects.

7. The insertion device according to claim 1, wherein the ejection position is situated between the receiving position and a coin output position in which the coin is transferred via the coin outlet.

8. The insertion device according to claim 1, wherein the flap can be moved into a closed position by a return spring.

9. The insertion device according to claim 1, wherein a detection sensor for establishing the approach of the coin is disposed in the region of the insertion slot and in that the rotatable drum, as a function of the signal of the detection sensor, can be rotated from an inoperative position in which the insertion slot is closed into the receiving position.

10. The insertion device according to claim 1, wherein at least one sensor for detecting the position of the rotatable drum and/or for detecting coins or other objects is provided.

11. The insertion device according to claim 10, wherein the at least one sensor is configured as one of a light barrier and a Hall sensor arrangement.

12. The insertion device according to claim 11, wherein the light barrier is disposed in the region of the receiving position and the output position.

13. The insertion device according to claim 1, wherein a sensor for detecting a position of the flap is provided.
