Description

[Detailed description of the invention] [Industrial application field] The invention connects a large number of product storage containers to a conveyor suspended in a vertical loop, and stores products in each of these product storage containers. This invention relates to a vending machine that automatically dispenses products by driving a conveyor according to a customer's request, and particularly relates to a conveyor drive device for driving the conveyor when filling products into a product storage container. .

[Conventional technology]

As shown in FIG. 1, this type of vending machine has a large number of product storage containers 2 connected and fixed to a conveyor 1 that extends in a vertical loop, and the conveyor 1 is operated by a conveyor motor, which will be described later. Each time a product is sold, one product storage container 2 is driven in the direction of arrow a. At this time, the product delivery lever 3 is rotated in the direction of arrow b, and the product 4 in the product storage container 2 is rotated.
is dropped onto the product delivery port 5 side, and at the same time, the delivery door 6 provided on the exit side of the product delivery port 5 is automatically opened in the direction of arrow c by a delivery door motor described later, and the product 4 is dropped into the direction of arrow c. It is designed to be dropped in the direction up to the outlet 7.

Here, when all the products 4 have been paid out, a message indicating that the products are sold out is displayed, and the product seller needs to confirm this display and fill the product storage container 2 with the products 4.

A conventional product filling device is shown in FIG. 2 (for example, Japanese Utility Model Application No. 52-54692).

Referring also to FIG. 2, when filling the product 4 into the product storage container 2 conveyed by the conveyor 1 through the product outlet 5, first, the sales/filling changeover switch 1 is turned on.
Switch 1 to the white circle contact (filling) side. This disconnects the sales circuit 12 from the power supply 13. next,
Close the carry-out door motor switch 14. At the same time, a switch 14a interlocked with the carry-out door motor switch 14 is opened. This causes the discharge door motor 15 to move and the discharge door 6 to open. This unloading door 6
When the switch 14 for the carry-out door motor is opened,
is opened (switch 14a is closed). Next, by closing the conveyor motor switch 16 (opening the switch 16a linked thereto), the conveyor motor 17 is moved and the conveyor 1 is driven. At this time, the conveyor 1 is reliably moved to a predetermined conveyor pitch by the conveyor motor 17 (this corresponds to the number of product storage containers 2 in the vertical direction facing the product exit 5, and in this embodiment, 4 conveyor pitches are set). ) The conveyor motor switch 16 must be opened (the switch 16a must be closed) so that the conveyor motor stops when it moves. After the conveyor 1 is stopped, the product 4 is stored in the product storage container 2 from the product carry-out port 5. When the storage is completed, the conveyor motor switch 16 is closed again and the same operation is repeated, so that all the products 4 are stored in the product storage container 2, and the unloading door 6 is closed, completing the filling of the products 4. do.

[Problem that the invention attempts to solve]

However, if the conveyor motor switch 16 is opened too early and the conveyor 1 stops before it moves four conveyor pitches, the number of products 4 that can be stored in the product storage container 2 at one time will decrease. The time required to fill the product 4 becomes longer. On the other hand, if the conveyor motor switch 16 is opened too late and the conveyor 1 moves more than 4 conveyor pitches and then stops, a product storage container 2 is created that cannot store the product 4. In order to store the products 4 in the product storage container 2, the conveyor 1 must be rotated one more time, and in this case as well, the time required to fill the products 4 increases. For this reason, for example, when the product is ice cream or the like, the product may be adversely affected.

Therefore, the product seller must ensure that conveyor 1 is
In order to operate the conveyor motor switch 16 so that the conveyor motor switch 16 can be stopped when the conveyor pitch has moved, it is necessary to learn the relative movement of the conveyor motor switch 16 and the product storage container 2 that moves in conjunction with this switch. However, there is a drawback that it takes time to learn the appropriate opening timing of the conveyor motor switch 16.

The purpose of the present invention is to provide a conveyor drive device for a vending machine that can reliably fill products in a short period of time.

Another object of the present invention is to provide a conveyor drive device for a vending machine that is easy to operate during filling and does not require skill to operate.

[Means for solving problems]

According to the present invention, a plurality of product storage containers 2 are connected to a conveyor 1 that is hung in a vertical loop, and when selling products, the products 4 stored in the product storage containers are
In a vending machine in which the conveyor 1 is driven by a conveyor motor 17 so as to dispense a predetermined number of products through an outlet 5, the conveyor motor 1
Product 4 is added to the conveyor drive circuit for driving Product 7.

a changeover switch 18 for operating the conveyor motor 17 when the conveyor motor 17 is filled; an automatic reset push switch 21 connected to the changeover switch 18 and generating a trigger for starting the conveyor motor 17; There is obtained a conveyor drive device for a vending machine characterized in that a control circuit 19 having a timer circuit for operating the conveyor motor 17 for a predetermined period of time is provided.

[Effect]

The product 4 is transferred to the product storage container 2 through the product delivery port 5.
When filling, the changeover switch 18 is switched to operate the conveyor motor 17. In this state, by pressing down the automatic return type push switch 21, a trigger for starting the conveyor motor 17 is generated. The timer circuit responds to this trigger for a predetermined time (predetermined conveyor pitch).
The conveyor motor 17 is operated so that the conveyor 1 moves by In this way, simply by pressing the automatic return type push switch 21, the conveyor 1 can be reliably moved by a predetermined conveyor pitch, so that even beginners can easily move the products 4 through the product exit 5 in a short time. The product storage container 2 can be filled.

〔Example〕

An embodiment of the present invention will now be described with reference to the drawings.

Referring to FIG. 3, a conveyor drive device according to an embodiment of the present invention includes a changeover switch 18 and a control circuit 19 instead of the conveyor motor switch 16 of FIG. A variable resistor 20 and an automatic reset push switch 21 are externally attached to the control circuit 19. The changeover switch 18 is
It will be turned over to the B side when filling the product. The control circuit 19 is
One anode is connected to the power supply 13 via the switch 11.
It contains a triax 19a whose other anode is connected to the B side of the changeover switch 18, and a monostable multivibrator (not shown) whose output is connected to the gate of the triax 19a.
The variable resistor 20 varies the time width of the square wave output from the monostable multivibrator of the control circuit 19. The self-resetting push switch 21 applies a trigger to the input of the monostable multivibrator of the control circuit 19.

Next, referring to FIGS. 1 and 3, the operation of filling products according to the present invention will be described. First, as in the past, the product seller operates the sales/filling switch 11.
After switching to the filling side, the carry-out door motor switch 14 is closed for a predetermined period of time, and the carry-out door 6 is opened. next,
Turn the changeover switch 18 to the B side. At this time, the switch 16a is opened in conjunction with the changeover switch 18. In this state, the self-resetting push switch 21
When is pressed, a trigger is input into the control circuit 19, and the monostable multivibrator generates a square wave for a certain period of time determined by the resistance value of the variable resistor 20 and the capacitance value of the monostable multivibrator capacitor. This square wave is input to the gate of the triax 19a, the triax 19a is turned on, and the conveyor motor 17 operates for the predetermined period of time and then stops.

Therefore, by providing scales 1, 2, 3, 4, . . . on the variable resistor 20 corresponding to the operating pitches of the conveyor 1, the conveyor 1 can be reliably moved by an arbitrary conveyor pitch. Furthermore, in order to start the conveyor motor 17, it is only necessary to lightly press the automatic reset type push switch 21, and after pressing the automatic reset type push switch 21, the conveyor 1 will automatically switch to the conveyor set by the variable resistor 20. Move just one pitch and then stop.
