Abstract

Disclosed is a coin handling apparatus 1 including: a transport unit 8 including a transport disk which moves a coin along a coin track; sorting units each of which sorts the coin when the coin falls into any of openings; a fall detector which detects the opening into which the coin has fallen; a motor which allows the transport disk to rotate; and a controller (controller) which stops the motor upon determining an occurrence of a transport error in the coin track, and identifies the opening into which the coin has fallen after the stop of the motor and during recovery from the transport error based on a detection result of the fall detector.

Claims

1. A coin handling apparatus, comprising:

an arcuate coin track configured to move a coin;

a transport unit comprising a transport disk that rotates about a shaft, the transport disk rotating with pressing an upper surface of the coin by a lower surface of the transport disk so as to move the coin in a single layer and a single file along the coin track;

a sorting unit comprising a plurality of openings provided in the coin track, and configured to sort the coin by making the coin moving along the coin track fall into any of the openings;

a fall detector configured to detect the opening into which the coin has fallen;

a motor configured to allow the transport disk to rotate; and

a controller configured to stop the motor upon determining an occurrence of a transport error of the coin in the coin track, and identify the opening into which the coin has fallen in a period from the stop of the motor to the end of recovery from the transport error based on a detection result of the fall detector.

2. The coin handling apparatus of claim 1, wherein the transport disk is arranged to face the coin track so as to sandwich the coin between the lower surface of the transport disk and the coin track when the transport disk moves the coin, and the lower surface of the transport disk during the recovery from the transport error is at a position further away from the coin track than a position at which the transport disk moves the coin.

3. The coin handling apparatus of claim 1, further comprising:

a display configured to display the opening into which the coin has fallen in the period from the stop of the motor to the end of the recovery from the transport error.

4. The coin handling apparatus of claim 1, further comprising:

a rotational angle detector configured to detect an angle of rotation of the transport disk.

5. The coin handling apparatus of claim 1, further comprising:

a recognition unit configured to recognize the coin; and

a rotational angle detector configured to detect an angle of rotation of the transport disk, wherein the sorting unit comprises a driving sorting unit which is arranged downstream of the recognition unit in a direction of movement of the coin, and is configured to selectively drop the coin into an associated one of the openings based on a recognition result and the angle of rotation of the transport disk, and

the controller identifies, based on a detection result of the fall detector and a detection result of the rotational angle detector, a position of the coin in the period from the stop of the motor to the end of the recovery from the transport error, the coin having already passed through the recognition unit when the transport error occurred.

6. The coin handling apparatus of claim 5, further comprising:

a display configured to display an identification result of the controller,

wherein the display displays the opening into which the coin has fallen in the period from the stop of the motor to the end of the recovery from the transport error.

7. The coin handling apparatus of claim 6, wherein

the display displays a position of the coin remaining on the coin track.

8. The coin handling apparatus of claim 6, wherein

the display displays the opening into which the coin has fallen, and information based on the recognition result for identifying the coin that has fallen into the opening.

9. The coin handling apparatus of claim 8, wherein,

the controller determines, based on the recognition result, that the coin has fallen into an inappropriate one of the openings in a period from the stop of the motor to the end of the recovery from the transport error, and

the display displays that the coin has fallen into the inappropriate one of the openings.

10. The coin handling apparatus of claim 4, further comprising:

a feeding unit comprising a rotating plate that rotates about a shaft, and configured to separately feed the coins on the rotating plate to the coin track by rotation of the rotating plate;

a belt wound around a first pulley that is allowed to rotate by the motor and the shaft of the transport disk, and configured to transfer a rotary force of the motor to the transport disk; and

a second pulley attached to the rotating plate, and arranged to be in contact with a back surface of the belt between the first pulley and the shaft of the transport disk, so that the rotating plate rotates in a direction opposite to a direction of rotation of the transport disk while the belt is running.

11. The coin handling apparatus of claim 10, further comprising:

a rotational speed detector configured to detect a rotational speed of the rotating plate,

wherein the controller compares a detection result of the rotational angle detector and a detection result of the rotational speed detector to determine whether a feeding error has occurred in the feeding unit.

12. The coin handling apparatus of claim 11, wherein

the controller stops the motor and reverses the direction of rotation of the motor to allow the rotating plate to rotate in a direction opposite to a feeding direction of the coin upon determining that the feeding error has occurred, and then resumes driving the motor to allow the rotating plate to rotate in the feeding direction of the coin.

13. The coin handling apparatus of claim 12, wherein, the controller reverses the direction of rotation of the motor so that the transport disk rotates in the opposite direction at an angle of rotation of 10 degrees or less, when the controller rotates the rotating plate in the opposite direction.

14. The coin handling apparatus of claim 11, wherein the rotational angle detector is an encoder provided for the shaft of the transport disk and configured to output a signal to the controller in accordance with the rotation of the transport disk.

15. The coin handling apparatus of claim 11, wherein the rotational speed detector detects that a projection provided for the rotating plate revolves in accordance with the rotation of the rotating plate.
