JPS592075B2 - Vending machine with discount sales function - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vending machine with a discount function.

In particular, this applies to vending machines that can sell products in succession each time the customer operates the selection switch as long as the remaining amount is still greater than the product's set price even if the customer operates the selection switch after inserting money and sells the item. It is something.

That is, the purpose is to increase the usage rate of the vending machine by giving a discount by returning a percentage of the total price to the customer when several products are sent out in a continuous sale.

An embodiment will be described below in detail with reference to the drawings, but the explanation will be based on the case where a discount is given to the number of sold products.

The figure shows the circuit of the invention in block diagram form.

Reference numeral 7 denotes an amount introducing pulse generator which, when detecting the insertion of a coin, outputs a pulse number corresponding to the amount to the amount counting device 1, and the amount counting device 1, for example, adds and counts the inserted amount and subtracts the remaining amount after sending out the product. It is a reversible counter that counts.

Therefore, when a calculation pulse is introduced into the a terminal, an addition operation is performed, and when it is introduced into the b terminal, a subtraction operation is performed.

The amount counted by the amount counting device 1 is displayed on the display 2.

Also, when money is first inserted into the vending machine and the amount counting device 1 counts the calculation pulses introduced from the amount introduction pulse generator 7 via the OR gate 01, an output is generated at the OR gate 02. With this output, a memory device, such as a flip-flop circuit FF, which is set while the amount counting device 1 counts and stores a predetermined amount, is inverted.

Then, the counting state of the amount counting device 1 is compared with the set price of the product in the saleability determination circuit 3.

The set price of the product is set in advance by a manual switch or the like, and if the counted amount is greater than the set price of the product, a sellable output is output to the sales signal generation circuit 4, and the selection circuit 8 becomes operational.

When the selection switch is operated by the customer, the sales signal generating circuit 4 outputs a sales signal to the product sending section 9 and also outputs a calculation pulse corresponding to the amount of the product to the b terminal of the amount counting device 1.

When the product detection device 10 confirms that the product has been sent out from the product delivery section 9, it outputs an addition pulse to the counter 5 for counting the number of products via the AND game (AND).

The AND gate AN is opened by the Q output of the flip-flop circuit FF, and the product detection device 10 has a gate switch near the product sales outlet and is configured to generate a pulse when it detects passage of a delivered product.

The merchandise is sent out in this way, and the remaining amount is counted by the amount counting device 1. This remaining amount and the product setting price are again compared in the sellable determination circuit 3, and if the remaining amount is larger, the above-mentioned sellable output is generated.

If the customer has the intention of continuing sales, the above-mentioned operation is repeated by operating the selection switch.

If the configuration is such that a discount is given when five products are sent out in a continuous sale, a quintal count is used for the product number counter 5, and when five of the above-mentioned addition pulses are counted, it becomes a carry and is sent to the discount device 6. The discount finger 4>11 is output.

For example, if the product unit price is 100 yen and you want to give a 50 yen discount to the total price of 500 yen when 5 items are purchased in a continuous sale, the discount device 6 will add 50 yen when discount finger 4>11 arrives. OR the calculation pulses corresponding to the amount information
The amount is transferred to the amount counting device 1 through the gate 01, and 50 yen is added thereto.

Continuous sales in the present invention will be clearly stated.

That is, after the customer inserts some amount of money into the vending machine and the amount counting device 1 starts counting, if the customer sends out the product or change, the remaining amount is counted, and if additional money is inserted, automatic addition counting etc. A sales process is defined as the period until the counted amount becomes zero as a result of a given counting operation accompanying the operation of a vending machine, and continuous sales is defined as when multiple products are delivered during this -sales process. do.

Therefore, the period from when an output is generated at the OR gate 02 and the flip-flop circuit FF is set until the amount counting device 1 counts zero, the output from the OR gate 02 disappears, and is reset by the output generated from the inverter 12 is continuous sales. It can be said to be a period.

The products sent out during this continuous sales period are counted by a product number counter 5, and are discounted when a predetermined number of products are sent out.

Furthermore, when the output of the OR gate 02 disappears, the reset signal output from the inverter 12 and delayed by the delay circuit 13 is output to the flip-flop circuit FF and is also input to the product number counter 5 to return it to zero. do.

Further, since the discounted amount added to the amount counting device 1 is displayed on the display 2, the customer can confirm that the discount has been given.

Therefore, the amount counting device 1 stores the following value (total input amount - total outgoing product price 10% discount amount), and the customer inserts additional money and purchases the product again based on this remaining amount. Alternatively, it is also possible to return the money as change by operating a return switch (not shown).

However, in the case of repurchase, the product number counter 5 overflows due to the discount operation described above, and the discount will not be applied unless a predetermined number of products are purchased in continuous sales.

In this example, the discount is achieved by counting the number of products sold in a row, but the same effect can also be obtained by counting the number of times the sales signal is output by the sales signal generation circuit 4 instead of counting the number of products. .

In particular, it is impossible to count the number of products in a beverage vending machine, so it is effective to count the amount of products through continuous sales using the latter method.

The discounts detailed above are intended to be given to customers who purchase multiple items, but such discounts have no meaning unless they are given to the same person.

However, in the present invention, after the amount counting device starts the counting operation when money is inserted, the counted amount becomes zero as a result of the counting operation accompanying the operation of the vending machine such as sending out products, dispensing change, and adding additional money. Since the period up to this point is viewed as a sales operation to the same person, if a predetermined number of products are delivered during that period, a discount can be reliably given to that customer.

Moreover, since the discount amount is automatically added and displayed on the amount calculation device, it is easy to handle for both customers and the vending machine manager, and the operating rate can be greatly increased.
