Description

[Detailed description of the invention] This invention provides a product stocker in the main body that has a product takeout port on the front, and allows independent stock sections to correspond to the product takeout port based on the appropriate drive operation of the drive source, and allows the product to be purchased. At the same time, the stock part stocked with the desired product is made to correspond to the product takeout port, and the takeout door provided at the product takeout port can be opened in conjunction with the insertion of coins, etc. (or the insertion of a product purchase card, etc.). The present invention relates to a vending machine having a structure in which only desired products can be purchased, and particularly relates to a sales signal output device in this vending machine.

In such a vending machine, each stock part is provided with a price display board and a switch activation protrusion (the mounting position on the back of the display board differs depending on the price of the price display board), and the other side of the main body is is provided with a plurality of price switches that can be selectively turned ON and OFF by the switch actuating protrusion, and the price switch corresponding to the product in the stock section corresponding to the product outlet is turned ON by the switch actuating protrusion. ,
Moreover, the structure is such that the product takeout door can be opened when the coins of that price section are inserted, but as the coin counting circuit is replaced by a combination of a relay circuit and the coin count increases, as the number of coins counted increases. The number of relays increases considerably, which inevitably leads to high costs.

The present invention was devised based on the shortcomings of the conventional devices, and uses a semiconductor circuit to construct a circuit that outputs a sales signal based on the price signal from the price switch and the input coin signal. The aim is to provide vending machines at low cost.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are a perspective view and a schematic side sectional view of a vending machine equipped with a vending signal output device according to the present invention. The main body for opening and closing includes a product takeout port 3, a selection button 4, a coin slot 5, a refund operating lever 6, a refund port 1, and a takeout door made of a transparent plate for opening and closing the product takeout port 3. 8 and a locking device 9 which controls the locking and releases the lock when a coin equivalent to the price written on the price display board described later is inserted into the coin slot 5.

The device main body 1, which is closed by such a main body field 2, is partitioned by a heat insulating partition material 10 into a product storage room 11 and a machine room 12, which serve as a refrigerating room. 11 includes an evaporator 15 that constitutes a cooling cycle together with a compressor 13 installed in the latter equipment room 12 and a condenser 14 located outside the main body, a rotating shaft 1γ, and a plurality of stocks formed radially around this shaft. a drive device 19 that includes a drive motor 20 and a reduction gear group 21 that rotates the product stocker 16 through its rotation shaft 1T;
are provided for each.

22 is the bottom of the product stocker 16 and each stock part 1
A mounting plate 23 is provided for each stock part 18 as a price display board corresponding to the number 8, and is fixed to the bottom surface of the stocker 16 as is clear from the enlarged view of the main part in FIG.
The product outlet (takeout door 8) is installed on the front of the product.
Price characters visible from the outside through 3 are marked in accordance with the price of the product stored in the corresponding stock section.

Further, three mounting members 24 are attached to the back surface of the price display plate 22 in a vertical manner, and the tips of the mounting members 24 are thinned to form a mounting portion 24'.

At the mounting portion 24' of these mounting members 24, a switch actuator 25 made of a hollow body with one side open as shown in FIGS. This ensures a tight fit as shown in Figure 5.

Note that this switch actuator can be attached to and detached from the mounting portion.

On the other hand, a board 26 (on which the rotating shaft 17, drive motor 20, etc. are supported) provided in the device main body 1 corresponding to the mounting member 24 has three price switches SW1 to SW1. SW3 are stacked vertically, and these contacts S1 to S3 come into contact with the switch actuator 25 as shown in FIG. 6 when the switch actuator 25 is fitted to the mounting member 24 as described above. Then, the price switch itself is turned on.

Now, to briefly explain the relationship between the mounting member 24 (switch actuator 25) and each price switch SW1 to SW3, as described above, the contacts S1 to S3 of each price switch SW1 to SW3 are opposed to each other. Coming price display board 22
Of the mounting members 24, the switch actuator 25 contacts only those that are fitted, and when it comes into contact, turns on the switch, but the state of whether the switch actuator 25 is fitted is 1. The prices are marked on the front of each price display board 22 and vary depending on the price, and are set in binary as shown in FIG.

In the example, there are three price switches, so for example, 100
All stages can be set from yen to 700 yen.

Now, the vending machine involved in the present invention has the above-mentioned structure, and when the selection button 4 is pressed, the driving force 20 is driven based on this, and in conjunction with this, the product stocker 1 is activated.
6 rotates.

Each stock section 18 of the rotating product stocker 16 faces the product take-out port 3 in turn, and when the stock section 18 containing the product desired by the purchaser comes to face the product take-out port 3, the above selection is made. By releasing the button 4, the drive motor 20 and the product stocker 16 immediately stop rotating.

Thereafter, when the purchaser inserts coins equivalent to the price shown on the price display board 22 of the stock section 18 facing the product outlet 3 through the coin slot 5, a control circuit to be described later is activated. It is configured to check whether the amount of coins collected coincides with the price value on the price display board 22, and when the coincidence is confirmed, send a ship sale signal to the lock device 9 to release the lock and enable the removal door 8 to be opened. has been done.

Next, a control circuit for confirming the match between the inserted coin and the product price and outputting a sales signal as described above will be explained with reference to FIG.

In the figure, C0-8W is a coin detection switch provided inside the coin insertion slot 5, which is turned on every time a coin is inserted and outputs a coin signal P1.

Reference numeral 27 designates a counter circuit unit for counting the number of coin signals P1 outputted from the coin detection switch co-sw, to which the coin signal P1 is inputted via the chattering prevention circuit unit 28. It is designed to receive a reset signal r and be reset when it is opened, when the refund switch is turned on, when the power supply circuit is turned on, etc.

A decode driver 29 receives a count signal P3 indicating a binary logical value outputted from the counter circuit section 27, decodes it, converts it into a 7-bit display signal P4, and operates the display device 30 at the next stage. This is the circuit section.

31 is a comparator that compares the count signal P3 output from the counter circuit section 27 and the product price signal P2 sent from the price switches SW1 to SW3, and when the information of both signals matches, it outputs a match signal P5. This is what is output.

Reference numeral 32 denotes an input terminal for inputting this coincidence signal P5, an input terminal for inputting the count signal P3 outputted from the counter circuit section 27 via the OR gate 33, and an input terminal for inputting the count signal P3 output from the counter circuit section 27, which is sent based on the movement of the drive motor 20. A Nantes gate is configured to have three input terminals, including an input terminal for inputting the signal (level only when the drive motor 20 is stopped) P6, and the output signal is input to one input terminal of the Nantes gate 34 at the next stage. ing.

The other input terminal of the Nantes gate 34 is configured to receive a signal P7 of 1 level when the take-out door 8 is closed.

Then, when the output of the Nantes gate 34 is at level 1, that is, when the sales signal P8 is output from the Nantes gate 34, the switch circuit section 35 consisting of a transistor is turned on.
L: The solenoid 9 of the locking device 9 is energized to unlock the extraction door 8.

Since the control circuit is configured in this manner, when the stock section 18 containing the desired product faces the product takeout port 3 in accordance with the pressing operation of the selection button 4 as described above, the respective price switches SW1 to SW1 are activated. SW3 is the mounting member 24 of the price display plate 22 of the selected stock section 18. Switch actuator in 25. . . . are turned on and off depending on the installation status of each.

Here, if the price of the desired product is, for example, 300 yen, as is clear from FIG. 7, the switch actuators 25 are fitted to the lower two mounting members 24, respectively, and therefore, the price switch SW1. SW2 is turned ON by the switch operator 25, and the price switch SW3 remains OFF. As a result, the product price signal P2 output from these price switches has the logical values of "1", 91", XXO". is input to the comparator 31.

On the other hand, in the coin detection switch co-sw, when the purchaser inserts coins corresponding to the price shown on the price display board 22 into the coin slot 5, ONL coins are generated each time a coin is inserted. Chattering prevention circuit part 2 made by Coin Signal 1
8 to the counter circuit section 2γ.

The counter circuit section 2γ counts the coin signal P1 and sends the result as a count signal P3 to the decode driver circuit section 29 and the comparator 31.

In the decode driver circuit section 29, such count signal P
Every time there is an input of 3, it is decoded and displayed as a display signal P4.
Then, the display device 30 is activated.

On the other hand, the comparator 31 compares the product price signal P2 and the coin count signal P3, and outputs a match signal P5 when the count signal P3 matches the product price signal P2.

When the coincidence signal P5 is output, the other input terminal of the Nantes gate 32 receives 1 through the OR gate 33.
When the signal P6 is input to another input terminal at this timing, the Nandt gate 32 outputs the signal P6.

Since this O level signal is input to the Nantes gate 34 together with the signal P7 (level 1) sent when the extraction door 8 is not opened, the sales signal P8 is output from the Nantes gate 34 and the switch circuit Turn on part 35
Then, the solenoid 9' of the locking device 9 is energized to unlock the extraction door 8.

Therefore, when the lock is released in this way, the purchaser can open the take-out door 8 and take out the product from the stock section 18.

In this way, when the take-out door 8 is opened, the reset signal r is input to the counter circuit section 2γ, so that the circuit section 2
7 returns to 0, and therefore, based on this, Nantes Gate 3
The output signal of 2 becomes l leher and the next Nantes gate 3
4 is input.

However, since the O-level signal P7 is inputted to the other input terminal of the Nantes gate 34 based on the opening of the extraction door 8, the extraction door 8 is input from the Nantes gate 34 again.
The sales signal P8 is successively outputted to keep the solenoid 9' energized until the solenoid 9' is closed.

After that, when the purchaser takes out the product and closes the takeout door 8, a signal P7 is input to one of the Nantes gates 340.
is at the 11" level, the sales signal P8 output from the Nantes gate 34 is deenergized, and the solenoid 9'
The energization is cut off again, and the take-out door 8 is locked again.

Since the present invention is constructed as described above, it is possible to construct a counting circuit and output a sales signal when a predetermined coin is inserted, without using a relay or the like as in conventional products. This will be advantageous in terms of cost.

In addition, by changing the switch operation means provided in each stock section of the product stocker, it is possible to set prices for various products, so it is possible to increase the variety of products for sale.
