Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application This invention relates to a vending machine that uses a bend motor to control the release of articles over a relatively long period of time.

Conventionally, in this type of vending machine, for example, when a predetermined amount of coins is inserted into a coin mechanism, a sales signal is output from the coin mechanism, and when a selection switch is operated in this state, a bend relay is activated. There is a known device in which the bend motor is activated and a signal is input to the coin mechanism to prohibit the acceptance of coins, and the bend motor is self-held by a cam switch interlocked with the bend motor.

However, conventional vending machines use only the bend relay to input a signal to the coin mechanism that prohibits coin acceptance. There was a problem in that the power consumption in the bend relay increased due to energization across the bend, and the life of the bend relay was shortened.

In addition, in order to avoid the bend relay being energized for a long time, it has been proposed to provide many relays in addition to this bend relay and use these to de-energize the bend relay (in practice). 1973-
134998). That is, in response to the input of a predetermined amount of money into the coin mechanism, the bend relay operates first, and when the selection switch is operated in this state, the selection relay is energized, and then the delivery relay is activated by the operation of the selection relay. is energized,
And the bend relay is deenergized. When the bend relay is deenergized after a predetermined delay time has elapsed, the bend mechanism is activated to sell the article.

However, there is a problem in that the use of such a large number of relays complicates the circuit, and there is still room for improvement.

Problems to be Solved by the Invention As described above, in conventional vending machines, a large burden is placed on the bend relay, resulting in problems such as increased power consumption and shortened lifespan.

This invention was made to solve this problem, and it is possible to reduce the operating time of the bend relay in a device that uses a bend motor to control the release of an article over a relatively long period of time. The purpose of the present invention is to provide a vending machine that does not require a complicated circuit for relay deenergization control.

[Configuration of the invention] Means for solving the problem The vending machine of the invention includes a coin mechanism that outputs a sales signal in response to the insertion of a predetermined amount of coins;
A bend motor that is energized and controls the release of goods to a sales outlet, and a bend relay that responds to the sales signal output from the coin mechanism to start energizing the bend motor and supplies an acceptance prohibition signal that prohibits the coin mechanism from accepting coins. and an acceptance prohibition signal that is linked to the rotation of the bend motor, keeps the bend motor energized for a certain period of time, de-energizes the bend relay, and prohibits the coin mechanism from accepting coins in place of the bend relay for the certain period of time. The system is equipped with a cam switch that supplies

Function In a vending machine configured as described above, when a predetermined amount of money is inserted into the coin mechanism, a sales signal is output from the coin mechanism, and the bend relay responds to this sales signal, causing the bend relay to operate. As a result of the operation, energization of the bend motor that controls the release of the article to the sales outlet is started, and an acceptance prohibition signal is sent to the coin mechanism to prohibit the acceptance of coins. On the other hand, when the bend motor starts rotating, a cam switch is activated to keep the bend motor energized for a certain period of time. At the same time, the bend relay is deenergized by the operation of this cam switch, and an acceptance prohibition signal is sent to the coin mechanism in place of this bend relay. Therefore, the acceptance prohibition signal is continuously input to the coin mechanism. Also,
The bend relay is deenergized when the bend motor starts rotating.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

FIG. 1 is a circuit diagram showing a vending machine according to an embodiment. That is, I ₁ and I ₂ are input terminals connected to a commercial AC power supply, 1 is a coin mechanism, 2a, 2b, 2c,
2d is a selection switch, 3a, 3b, 3
c, 3d are selection relays, 4a, 4b, 4
d, 4e are bend motors, 5a, 5b, 5c, 5
d is a sold-out switch; 6a, 6b, 6c, and 6d are sales lamps; 7a, 7b, 7c, and 7d are sold-out lamps; 8a, 8b, 8d, and 8e are cam switches;
9 is a bend relay. In this device, the article storage section is divided into four rooms, and each room is provided with a selection switch, a selection relay, a bend motor, a sold-out switch, a sales lamp, a sold-out lamp, and a cam switch.

The coin mechanism 1 has 10 pins, and the pins are connected to the input terminal I ₁ and the input terminal I ₂
When a predetermined amount of coins are inserted, a sales signal is output to the pin, and when a signal, that is, an acceptance prohibition signal, is input to the pin, the signals from each of the pins ~, are output. The output of the sales signal is stopped and the acceptance of coins is prohibited. Reference numerals 10a and 10b are price setters that set the selling price to two prices, and 11 is a price setter that sets the price of each room. The price number setter 10a has a ~ terminal and is connected to the output pins of the coin mechanism 1 in a relationship of ~, -, -, -, -, and the price number setter 10b has a ~ terminal. and is connected only in a negative relationship to the ~ terminal of the price setting device 11. The two price number setters 10a and 10b are configured such that their respective terminals are connected to each other. Further, a pin of the coin mechanism 1 is directly connected to a terminal of the price setting device 11. The price setting device 11 is also provided with terminals - corresponding to each room, and connected to each terminal in a -, - relationship as shown by dotted lines in the figure. That is, the coin mechanism 1, price setting devices 10a, 10b, price setting device 11
Therefore, two of the four rooms are priced at the same price.

When a predetermined amount of coins is inserted into the coin mechanism 1, a sales signal is output from each terminal ~ of the price setting device 11, and in this state, the input terminal I ₂ → the normally closed contact of the bend relay 9 → the sold-out switch 5a ~
5d → sales lamps 6a to 6d → diode 12a
~12d→Selection relay 3a~3d→~
Sales lamps 6a to 6d are connected by loops of each terminal of
is starting to light up. In this state, when one of the selection switches 2a-2d is operated, the corresponding selection relay and bend relay 9 are energized and the sales lamps 6a-6d are turned off. Further, when one of the selection relays 3a to 3d is energized and the bend relay 9 is energized, one of the bend motors 4a to 4d corresponding to the energized selection relay is energized, and the diode circuit is activated. 13, an acceptance prohibition signal is inputted to the pin of the coin mechanism 1 to stop the output of the sales signal and to prohibit the acceptance of coins. When the bend motors 4a to 4d are energized, they start discharging the article and the corresponding cam switch 8a is activated.
8d to open the normally closed side and close the normally open side. Then, by switching the cam switches 8a to 8d, the corresponding bend motors 4a to 4d are self-held, and the bend relays 9 and the corresponding selection relays 3a to 3 are
d is released from self-holding, and an acceptance prohibition signal is supplied to the pin of the coin mechanism 1 via the diode circuit 13 instead of the bend relay 9.
Note that a delay circuit 14 is connected in parallel to the bend relay 9 so that the self-holding state is released with a slight delay. After a certain period of time, the cam switch returns to its original state and the corresponding bend motor stops.

The diode circuit 13 includes, for example, a coupler 13a connected to the coin mechanism 1 and a coupler 13b connected to the vending machine main body as shown in FIG. 2, and four diodes are connected between the couplers 13a and 13b.
It is designed to insert D ₁ to D ₄ .

For example, if a predetermined amount of coins is inserted into the coin mechanism 1 and the selection switch 2a is operated while the sales lamps 6a to 6d are lit, the selection relay 3a is energized and the normally closed side of its switching contact is closed. Other selection relays 3b to 3d
The bend relay 9 is energized through the normally closed side of the switching contact in series. In addition, by closing the normally closed side of the other switching contact of the selection relay 3a, the normally closed side of the other switching contacts of the other selection relays 3b to 3d are connected in series, and further the normally open switching contact of the bend relay 9 is closed. The bend motor 4a is energized through the side and starts rotating. When the bend relay 9 is energized, the selection relay 3a switches its switching contact to the normally open side, the switching contacts of the other selection relays 3b to 3d to the normally closed side, the bend relay 9's switching contact to the normally closed side, and the cam switch. Since the selection switch 2a is self-maintained via the normally closed series circuit of 8a to 8d, there is no problem even if the selection switch 2a returns in a short time. When the bend motor 4a rotates, the cam switch 8a operates, opening its normally closed side and closing its normally open side. As a result, the bend motor 4a is self-supported via the normally open side of the cam switch 8a. Further, by opening the normally closed side of the cam switch 8a, the self-holding of the selection relay 3a is released. As a result, the self-holding of the bend relay 9 is released with a slight delay by the delay circuit 14. When the normally open side of the cam switch 8a is closed, this cam switch 8a
and the coin mechanism 1 via the diode circuit 13.
An acceptance prohibition signal is input to the pin of , and the acceptance prohibition signal is input instead of the bend relay 9. Then, after a certain period of time has elapsed and the bend motor 4a rotates, for example, once, the cam switch 8a returns to its original state, the power to the bend motor 4a is cut off, and one cycle of the sales operation is completed. Note that when the items in the room are sold out, the sold-out switch 5a is switched and the sold-out lamp 7a is turned on.

In this way, the bend relay 9 can be operated in a short time from when the selection relay starts operating by operating the selection switch until the cam switch is switched and operated by the bend motor, so power consumption in the bend relay can be kept low. At the same time, it is possible to prevent the life of the relay from decreasing. Since a cam switch that self-holds the bend motor is used to control the de-energization of the bend relay 9, there is no need to use a separate relay or the like for de-energizing the bend relay, and the circuit configuration is simple. Furthermore, even if the bend relay is deenergized, the input of the acceptance prohibition signal for prohibiting coin acceptance is maintained in the coin mechanism 1 via the cam switch, so there is no risk of malfunction.

In the above embodiment, four types of articles can be selectively sold, but the present invention is not limited to this, and any number of types can be sold.
However, in the case of one type, the selection switch and selection relay can be omitted.

Furthermore, in the above embodiment, the coin mechanism was set and used for two-price sales, but it can also be set for three or more prices. For example, when the coin mechanism is used for three-price sales, the diode circuit 13 is All you have to do is reverse the direction _of the diodes _D1 to _{D4 .}
This can be done easily since it is inserted between a and 13b.

[Effect of idea]

As detailed above, according to this invention, the bend relay is energized by the sales signal generated in response to the insertion of a coin into the coin mechanism, and then deenergized by the operation of the cam switch by the bend motor, and the bend relay is activated. Since the cam switch is made to do this, the operating time of the bend relay can be shortened. Therefore, the power consumption in the bend relay can be reduced, the life of the bend relay can be prevented from being shortened, and the circuit configuration is simple and practicality can be improved.
