Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a vending machine that tallies sales using an electromagnetic counter.

(b) Conventional technology Vending machines whose sales are tallied using an electromagnetic counter are
It is well known, for example, as disclosed in Japanese Patent Publication No. 57-3119. However, in conventional vending machines, the control unit and the electromagnetic counter are connected one-to-one, so a system in which multiple electromagnetic counters are installed depending on the tabulation items requires a large number of input/output terminals for the control unit, which creates a large burden. I was getting used to it.

(c) Problems to be solved by the invention As described above, conventional vending machines required signal lines between them and the control unit depending on the number of electromagnetic counters.

Therefore, the present invention provides a vending machine in which the output line between the control section and the electromagnetic counter is effectively connected.

(d) Means for solving the problem The present invention has a plurality of bus lines corresponding to a plurality of product columns, and each of the bus lines has a product drive device and a switch device for the corresponding product column. In a vending machine in which a control unit is connected to one end of the bus line and is equipped with a bus set device for driving the bus line, the vending machine is connected to A plurality of electromagnetic counters are provided and each connected to a predetermined bus line, and the order of the selected product sales price during the product sales operation is determined based on the magnitude, and the predetermined bus line is driven according to the determined order. This configuration includes a price ranking determination device that controls the bus set device.

(E) Effect When the vending machine starts selling a product, the price ranking determination device determines the ranking based on the size of the selected product sales price among the product sales prices set for the vending machine, A bus set device is controlled to drive a predetermined bus line according to the determination order. As a result, an electromagnetic counter connected to the driven bus line operates to count the sales of the sales operation.

(F) Embodiment FIG. 1 shows a wiring diagram of a vending machine according to the present invention, and the vending machine of this example has four product columns. Therefore, in this example, there are four bus lines BUS1 to BUS corresponding to each product column.
4, and the control section 3 has a common output terminal.
Motors M1 to M4, which are product drive devices for corresponding product columns, are connected between Com1 and bus lines BUS1 to BUS4, respectively. And common output terminal Com3 and each bus line BUS1~BUS
4 are connected with electromagnetic counters C1 to C4 for counting the number of products sold according to the order of the product sales price. Furthermore, each motor M is connected between the common input terminal Com2 and each bus line BUS1 to BUS4.
Cam switches CS1 to CS4 corresponding to 1 to M4 are connected. The cam switches CS1 to CS4 detect one rotation of a cam that rotates in conjunction with the drive of the motors M1 to M4, respectively, and the product is delivered by one rotation of this cam.

FIG. 2 shows the specific configuration of the control unit 3, where 5 is an amount calculation device that calculates the input amount based on the input money signal CN, and 4 is the sales price where the sales prices of four types of products are respectively set. A setting device 6 is a vending judgment device S that compares the input amount with the selling price of the product and determines the products that can be sold according to the presence or absence of change stored in the vending machine and the presence or absence of the product.
1 to S4 are product selection switches corresponding to the product columns, respectively. Reference numeral 7 denotes a sales control device, which outputs product information _D1 indicating the type of product when a product determined to be sellable by the sellability determining device 6 is selected by the selection switches S1 to S4. Reference numeral 1 denotes a price ranking determining device, which compares the selling prices set in the selling price setting device 4 through the operation of selection switches S1 to S4, and determines the ranking based on the size of the selling price of the selected product. 2 is a bus set device which selects a specific bus line based on product information D ₁ or price ranking information D ₂ generated in the price ranking determining device 1.
Drives BUS1 to BUS4. Specifically, when the product information _D1 is input and the product is dispensed, the bus set device 4 outputs "H" to the common output terminal Com1, and also outputs "H" to the common output terminal Com1, and also outputs "H" to the bus line BUS1 corresponding to the product column in which this product is sold. “L”
By doing so, the bus line is driven for sales operation. As a result, the motor corresponding to the driven bus line operates, but the bus set device 4
can detect the operation of the cam switch corresponding to the driven motor by detecting the input state to the common input terminal Com2. In addition, when price ranking information is input by _D2 and the electromagnetic counter is operated, "H" is output to the common output terminal Com3, and the bus line corresponding to the price ranking is output.
By setting BUS1 to "L", the bus line is driven for sales aggregation.

The operation according to the above configuration will be explained with reference to the timing chart in FIG. By inserting money into the vending machine, the amount calculating device 5 calculates the amount of money inserted, and the saleability determining device 6 determines the products that can be sold with this amount of money inserted. When a product that can be sold is selected, for example, by operating the selection switch S1, the sales control device 7 outputs product information _D1 , and the bus set device 2 outputs "H" to the common output terminal Com1. Bus lines that correspond to this product type
Set BUS1 to “L”. Therefore, motor M1
This will drive the sales operation of this product. Motor M
When the cam starts rotating in conjunction with 1, cam switch CS1 changes from ON to OFF, but at the end of one rotation of the cam, cam switch CS1 changes from OFF again.
When the bus set device 2 detects that it is turned on by the input signal to the common input terminal Com2, it stops the output of the common output terminal Com1 and sets the bus line BUS1 to "H" like the other lines, so that the motor M1 is turned on. Stop driving. Next, the bus set device 2 outputs "H" to the common output terminal Com3,
Based on the price ranking information _D2 , any of the bus lines BUS1 to BUS4 is driven again. For example, if the product corresponding to the selection switch S1 is ranked fourth in selling price, the bus line S4 is set to "L". As a result, the electromagnetic counter C4 is energized and counts up. At this time, the bus set device 2 outputs "H" to the common output terminal Com3 for 100 ms required to drive the electromagnetic counter C4.

(g) Effects of the invention According to the invention, since the electromagnetic counters are connected to the bus line in a matrix, there is no need for an output line exclusively for the electromagnetic counters. Therefore, the number of input/output terminals of the control section can be reduced, and wiring can be reduced. Moreover, it is not necessary to provide an electromagnetic counter for each product column in order to sequentially calculate the number of sold items depending on the size of the selling price, and a plurality of electromagnetic counters can be effectively driven.
