In the product dispensing device of the vending machine of this type, the second switch 5 for detecting the dispensing state while the above-described dispensing operation is repeated based on the product dispensing command.
3 may break down, but in this case, in the conventional case, the second switch 53 is used to detect the second cam surface 51 of the detection operation cam.
Since it cannot be turned on by b or the third cam surface 51c, the motor continues to rotate as shown in (c) and (d) of FIG. The first switch 52 is operated by the first cam surface 51a, and the detection operation of the first switch 52 stops the driving of the motor. As a result, while the motor rotates 360 °, the rotation cam 54 that rotates integrally with the drive shaft 50 causes the one stopper 5 to rotate.
After 5 is switched from the product receiving position to the product delivering position, the other stopper 55 is also similarly switched from the product receiving position to the product delivering position, so that the product G is delivered from both the left and right product storage units. there were. The present invention is
The present invention has been made in view of the above circumstances, and its purpose is to stop driving a 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 be able to do it.

[0004]

In order to achieve the above-mentioned object, in the product dispensing device for a vending machine according to the present invention, which has the above-mentioned configuration, A. A fourth cam surface for actuating the first switch is formed in a portion of the detection operation cam having a phase difference of 180 ° in the rotational direction with respect to the first cam surface. Is provided, and the action and effect thereof are as follows.

[0005]

Even if the second switch for detecting the payout state fails during the payout operation based on the product payout command and the motor is continuously driven even after the predetermined product is paid out, the detection operation cam is 180 At the time of rotation, the first switch for detecting the payout standby state is operated by the fourth cam surface, and the motor is stopped by the detection operation of the first switch.

[0006]

Therefore, even if the second switch for detecting the payout state fails, the motor can be stopped before the stoppers other than the payout target are switched to the payout position. It has become possible to reliably prevent products from being dispensed from both product storage units.
