Due to 4, only the right stopper 55 is switched from the product receiving position to the product payout position, and the lowermost product G stored in the right product storage unit is paid out. When the commodity G corresponding to the commodity dispensing instruction is dispensed, the drive shaft 50 is driven to rotate leftward in the reverse direction by the motor, and the first switch 52 for detecting the dispensing standby state is turned by the first cam surface 51a at the time when the drive shaft 50 is rotated 90 °. When the first switch 52 is activated, the motor is stopped. In this state, the left and right stoppers 55 are both held at the original product receiving position by the rotating cam 54 that rotates integrally with the drive shaft 50. Further, when the commodity G is dispensed from the commodity storage unit located on the left side, the drive shaft 50 is driven to rotate leftward by the motor, and the second switch 53 for detecting the dispensed state is turned to the third switch when the drive shaft 50 rotates 90 °. The motor is driven by the cam surface 51c, and the motor is stopped by the detection operation of the second switch 53. In this state, only the stopper 55 on the left side is switched from the product receiving position to the product dispensing position by the rotating cam 54 that rotates integrally with the drive shaft 50, and the lowermost product G stored in the left product storage unit is removed. Will be paid out. When the product corresponding to the product delivery order is paid out,
The drive shaft 50 is reversely driven rightward by the motor,
At the time of rotation by 90 °, the first switch 52 for detecting the pay-out standby state is operated by the first cam surface 51a,
The driving of the motor is stopped by the detection operation of the switch 52. In this state, the left and right stoppers 55 are both held at the original product receiving position by the rotating cam 54 that rotates integrally with the drive shaft 50.

[0003]

In this kind of vending machine, the second switch 5 for detecting the state of payment is repeatedly used while repeating the above-described payment operation in accordance with the product supply command.
In this case, the second switch 53 is conventionally connected to the second cam surface 51 of the detecting operation cam.
24B or the third cam surface 51c, the motor cannot be turned ON, so that the motor continues to rotate as shown in FIGS. The first switch 52 is actuated by the first cam surface 51a, and the detection of the first switch 52 causes the motor to stop driving. As a result, while the motor rotates by 360 °, one of the stoppers 5 is rotated by the rotating cam 54 that rotates integrally with the drive shaft 50.
After the product 5 is switched from the product receiving position to the product payout position, the other stopper 55 is also switched from the product receiving position to the product payout position, so that the product G is paid out from both the left and right product storage units. there were. The present invention
In view of the above circumstances, the purpose is to stop driving the motor at the time of dispensing a predetermined product even if the second switch for detecting the dispensing state fails during the dispensing operation. The point is to make it possible.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, a vending machine product dispensing apparatus according to the present invention has the above-mentioned configuration. A fourth cam surface for operating the first switch is formed in a portion of the detection operation cam having a phase difference of 180 ° in a rotation direction with respect to the first cam surface. The function and effect of the above are as follows.

[0005]

When the second switch for detecting the dispensing state fails during the dispensing operation based on the commodity dispensing command and the motor is continuously driven even after the dispensing of the predetermined commodity, the detection operation cam remains at 180. At the time of the rotation, the first switch for payout standby state detection is actuated by the fourth cam surface, and the motor is stopped by the detection operation of the first switch.

[0006]

As a result, even if a failure occurs in the second switch for detecting the dispensing state, the motor can be stopped before the stopper not to be dispensed is switched to the dispensing position. It has become possible to reliably prevent the product from being paid out from both the product storage units.
