Abstract

PURPOSE:To halve the trouble occurrence rate due to the switches and to omit the ten-key input and preset switching operations which are required for each supply of commodities by deciding the sold-out state from the total stock of the commodities. CONSTITUTION:A control means 5 obtains a signal from a commodity detection means 3 for each application of the switch 3 and carries out an arithmetic operation based on the data to output a carry-out command. At the same time, the means 5 decides a sold-out state from the total stock of the commodities and outputs a sold-out command and a carry-out stop command. A carry-out means 4 carries out the commodities based on the command of the means 5. Then the continuous applications or the single application of the switch 3 is decided. Then 1 is added to the total stock with the single application of the switch 3. Meanwhile the full-stock number state where the total stock is optionally set is preset with the continuous applications of the switch 3. Furthermore the presence or absence of the sale output of commodities is confirmed. Then 1 is subtracted from the total stock with presence of the sale output. Meanwhile a sold-out state is decided and a sold-out signal is outputted to a sold-out lamp 10 when the total stock is equal to the sold-out decision number. Thus it is possible to prevent such an inconvenient case where the matching of data is not secured due to the misoperations of the ten keys or a preset switch or much time/labor is required for these operations.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a vending machine that sells beverages in cans, and more particularly to a vending machine sell-out control device that controls sell-outs based on the number of products in stock.

[Prior art] Conventionally, the vending machine with this scale has a sold-out method for counting the number of items in stock. There is a method of counting up the numerical value counted by a product supply number reading device, or a method of adding up the number of stocks using a preset switch that presets when the product is full, and then subtracting this number of stocks for each bend.

Also, the determination of whether the product is sold out is made according to whether the input of a sold-out switch is turned ON or OFF. Therefore, the addition input from the power key, preset switch, replenishment switch, etc. is an operation only for controlling the stock quantity, and the addition input and the stock quantity themselves are not related to the determination of sold-out.

[Problems to be Solved by the Invention] However, in conventional devices, when controlling the inventory quantity by inputting from a replenishment switch, a sell-out switch is provided separately, so a total of two or more input reading devices are required. I will do it.

Furthermore, detecting the number of remaining coins using a coin mech also requires two or more reading devices, which increases costs.

In addition, the method of adding up the inventory quantity using a numeric keypad or preset switch has the problem that the numeric keypad or preset switch must be pressed, and if the operation is forgotten, the data will not match and the operation is time-consuming.

An object of the present invention is to eliminate the above-mentioned problems and provide a sell-out control device for a vending machine.

[Means for Solving the Problems] As shown in FIG. 1, the present invention provides a vending machine that accepts coins and sells products, and includes an inserted product detection means for detecting that a product has been inserted into a rack; A means for adding the number of supplies or making the stock count full by detecting the inserted product detection means, a means for subtracting the stock number by carrying out the product, a data storage means for storing the number of stored items in the JI7F, etc. Every time a product is sold out, it obtains a signal from the product detection means, calculates it based on the data, outputs a carry-out command, determines whether it is sold out based on the number of items in stock, and issues a sell-out command;
A control means for outputting a command to stop carrying out; and a carrying-out means for carrying out the product based on the command of the control means.

[Function] According to the present invention, the product detection switch that detects product insertion determines whether the product is continuously introduced or one product is introduced, and if not, in other words, if one product is introduced, 1 is added to the stock quantity; Preset the inventory quantity to an arbitrarily set full quantity.

Next, it is determined whether there is a sales output for the product, and if so, the number of stocks is subtracted by 1, and it is determined whether the number of Mr. When they are the same, it is determined that the items are sold out and a sold out signal is output.

[Embodiment] FIG. 2 is a block diagram showing an embodiment of the sold-out 1I11 control device of the present invention.

In the figure, 1 is a rack installed inside the vending machine, 2 is a new can product, 3 is a product detection switch that is pressed down once when one product is put in, and 4 is a delivery solenoid as a product delivery means. , 5 is a CPU that executes the processing procedure shown in FIG. 3, 6 is a ROM that stores programs corresponding to the processing procedure, and 7 is data from an input device (not shown), that is, the set price and the inventory of can products in the rack. 8 is a backup power source that stores the data stored in RAM 7, 9 is a digital display that displays the number of items in stock, and 10 is a sold-out lamp that displays sold-out items.

The operation of the apparatus shown in FIG. 2 will be explained below with reference to the flowchart shown in FIG.

In such a configuration, first, in step 1, it is determined whether or not the product detection switch 3 has been activated, and if it has been activated, in step 2, the product detection switch 3, which is pressed down once when one product 2 is inserted, is continuously pressed. It is determined whether it is ON or not, and if it is not, that is, if one piece is inserted, the RA is set in step 3.
Add 1 to the stock quantity stored in M7 and proceed to step 5. In the case of continuous input due to continuous input, the stock quantity is preset to an arbitrarily set full quantity in step 4.

Next, in step 5, it is checked whether there is a sales output for the product, and if so, in step 6, the stock quantity is subtracted by 1, and then in step 7, it is determined whether the stock quantity is greater than the sold-out judgment number to determine that it is sold out. do. If it is large in step 7, then in step 8 the output of the sell-out signal is stopped and the process returns to step 1.
If the stock quantity is the same as the sold-out determination number, a sold-out signal is output in step 9, and the process returns to step 1. Note that step 5
If there is no sale, proceed to step 7.

[Effects of the Invention] According to the present invention, by determining whether a product is sold out based on the number of products in stock, it is possible to control the number of products in stock and whether the product is sold out with only one switch for manual reading and one switch for product detection. Therefore, the product cost can be reduced, the failure rate caused by the switch can be halved, and the labor of manipulating the numeric keypad and preset switch operations each time a product is replenished can be omitted.
