Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a device for restoring a drive motor in the event of a breakdown in a vending machine, in which drive motors provided for each type of product are controlled by a single switch.

(B) Prior art In general, in the case of cigarette vending machines that sell products by motor drive, a plurality of product storage tubes are arranged side by side in which products are piled up, and the bottom of each product storage tube is equipped with a device for dispensing products. A mechanism is provided, and the operation of the product selection switch drives the corresponding sales drive motor to send out the lowest product in the product storage cylinder (Utility Model Application No. 112781/1981).

Additionally, this type of vending machine is known to be configured to stop selling a product if it is not finished within a predetermined time.
For example, it is shown in Utility Model Application No. 56-53265.

(c) Problems to be solved by the invention In such conventional vending machines, if the reset switch, which is activated by the dispensed product, is not activated within a predetermined time period that is longer than the preset vending operation time, Regardless of the condition, all products will be discontinued due to the drive motor being interrupted due to product jamming, etc., so there is a problem that even products in product storage tubes that have not had any problems will be discontinued from sale. .

In addition, if the product delivery mechanism stops mid-operation due to a product jam, etc., and the drive of the vending drive motor is interrupted, the administrator will remove the product jam, etc., and then manually restart the product delivery mechanism that is in the middle of operation. It was necessary to perform a pressing operation or the like to return it to the standby position, which was time-consuming.

Based on the above points, the present invention is designed to discontinue sales of only the corresponding product storage tube or all sales depending on the state of drive interruption when the drive motor is interrupted. It is an object of the present invention to provide a device that can reduce the amount of power required and drive the interrupted drive motor again to return it to a standby state after removing the cause of the interruption of the drive motor.

(d) Means for solving the problem The device of the present invention outputs a selection signal when a selection operation is performed when a sellable signal is generated by inserting a predetermined currency, and responds by inputting a stop signal and a selection signal. a selection circuit unit that disables selection of the selection series;
When the selection signal is input while the control switch is in the standby state, the drive motor is driven to operate the product delivery mechanism, and the control switch, which has been switched to the operating state by the operation of the product delivery mechanism, returns to the standby state. a motor control section that stops the drive motor when the drive motor returns to normal or when a stop signal is input; and a timer that operates based on the generation of the selection signal. a series stop circuit section that sometimes outputs a stop signal; and a series stop circuit section that outputs a stop signal when the control switch does not return from an operating state to a standby state within a predetermined time of a timer that operates based on the generation of the selection signal. an all-column stop circuit section; a storage section that stores the selection signal upon input of a stop signal from the all-column stop circuit section or the series stop circuit section; and an input selection signal from the storage section upon input of a return signal. a set section that operates the drive motor until the control switch returns to the standby state, and outputs a reset signal to the storage section, the series stop circuit section, and the all column stop circuit section after the drive motor is stopped; Become.

(E) Effect If the product delivery mechanism stops for some reason with the control switch in the closed state of the standby state during the product delivery sales operation, only the corresponding product delivery mechanism will be discontinued and the control switch will be placed on standby. If the product stops when the state changes from the open state to the closed operating state, sales of all product delivery mechanisms will be discontinued.

In any of the above cases, when the return switch is manually operated after removing the cause of the stoppage and a return signal is input to the set section, the set section will respond to the input of the selection signal stored in the memory section and reset the series stop circuit section or the entire system. The vending drive motor whose drive was interrupted is operated again in response to information from the column stop circuit section. When information is being input from the series stop circuit section, the control switch changes from the operating state of the closed state to the standby state of the open state, and when information is being input from the all-column stop circuit section, the control switch changes from the operating state of the closed state to the standby state of the open state. When it returns to the open state, which is the standby state, the setting section stops the vending drive motor that is currently being driven, and
A reset signal is output to the storage section, the series stop circuit section, and the all-column stop circuit section to return to the sales standby state.
