Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vending machine sales control system, and in particular, it is capable of arbitrarily setting and changing the selling price on the main body control circuit side of the vending machine, and is also comprehensively equipped with these functions. This invention provides an inexpensive sales control system in which the price setting section .beta. can be freely increased or decreased, and only one sales output determination section is required to determine whether or not a product can be sold at the time of sale.

Conventionally, in this type of sales control system, as shown in FIG. 1, when predetermined coins are put into the coin sorting device 1, a coin sorting device 1 is installed.

A denomination signal corresponding to the input amount is applied to the central processing control unit 2 (a device that performs addition/subtraction storage and arithmetic control of the inserted coins), and the central processing control unit 2 outputs COM DATA containing the coin coins for each product column. The judgment elements of the sales output judgment unit 3 disposed in (parts such as small rooms where products are stored in a predetermined state) were configured to output the respective judgment elements.

Therefore, in the sales output determination unit 3, there are a price setting switch 4 provided corresponding to each product column, and a set price serial conversion unit 5 that converts the setting signal output from the switch into a predetermined price signal. Price setting section 6 consisting of etc.
When the output signal unit 3 matches the price signal SP, that is, when “coin data≧SP”, the output element of the sales output determination unit 3 outputs the collected light output signal VND, which is controlled by the main body of the vending machine. Since it is possible to output the signal to one terminal A of the selection switch 7 corresponding to the sales output determination section 3 through the circuit, the selection signal generated by pressing the selection switch 7 is configured by a selection relay or the like. The selected price is outputted via the sales channel storage section 8 to the selection price control unit 10 (described later) corresponding to the above-mentioned push switch and the product delivery section 9 (the part that operates the drive motor to send out the desired product to the product output port). It looked like it was going to happen.

Therefore, the SP multiplication signal corresponding to each selection switch is applied to the selection price control section 10 provided on the coin sorting device 1 side from the price setting section 6 provided for each product column as described above. When the selection signal pressed by is applied via the sales channel storage section 8,
A logical product including SP is output from a predetermined AND circuit (not shown) provided in the control section 10.

In other words, since the set price SP corresponding to the pressed selection switch is output to the central processing control section 2 in the coin sorting device 1, in the central processing control section 2, the self Since it is possible to compare the sales start signal S outputted via the OR circuit 11 when the holding circuit is formed with the total input amount already stored at the time of input, the central processing control unit 2
The amount of the sent product is subtracted from the stored contents.

Also, if the vending machine is equipped with an amount display to display the amount inserted, it goes without saying that the display will automatically change from the amount displayed at the time of insertion to the remaining amount after subtraction, so this is omitted. do.

In other words, in the conventional sales control system, the price setting section etc. are located on the coin sorting device side, so it is difficult to control the sales system of vending machines (single-bend method). When changing from a serial buying system (i.e., to a multi-bend system, etc.), it was impossible to change the sales system unless the coin sorting device was replaced with a coin sorting device that matched the desired sales system.

In addition, when making changes, etc., there was a big drawback in terms of change costs and the like.

Furthermore, the vending machine itself is expensive in terms of manufacturing costs because the sales output determining section is provided in each product column.

The present invention provides a sales control system that solves these problems with ease and is inexpensive to manufacture.

One embodiment will be described below in detail based on FIGS. 2 and 3. First, in FIG. Judgment 'A'
'J=β (not shown), an addition/subtraction storage device (not shown) that stores information through operations such as addition and subtraction of coins after discrimination, and an arithmetic control unit that performs arithmetic control of these operations, as will be explained later. A transfer pulse generator TR, etc. consisting of a commonly known multi-by-break, which sends clock pulses to a sales output determination section (not shown) and a sales channel storage section 13 via a sales channel storage control section 14, is provided.

Note that the sales channel storage control unit 14 itself has an internal delay flip-flop knob DFF that outputs with a 1-bit delay.
(A) and (B), so when a clock pulse is sent from the above-mentioned pulse generator, it is also used as a write pulse for the DFF.

Reference numeral 15 denotes a control hook on the main body side, and inside the box there is a price setting section 18, which consists of a price setting switch 16- and a set price serial conversion section 11 for converting the signal output from the switch into a predetermined price signal. A sales channel storage unit 13 for storing the desired selection switch 19 pressed by the product or customer, etc.Furthermore, the selection signals stored from the output elements Q1 to Q3 of the channel storage unit 13 are sent to a selection price control unit to be described later. When outputting to the sales channel storage unit 13, the clock pulses outputted from the transfer pulse generator TR, which is composed of the generally known multi-by-break described above, are synchronized in the sales channel storage unit 13. The selection signal is added to the clock pulse applied via the sales channel storage control section 14, which is provided to control the selection price control section 20.
It is configured so that it can be output to.

Furthermore, the sales channel storage control section 14 can also control a reset signal for resetting the contents stored in the sales channel storage section 13 (such as the selection switch that was pressed). It is composed.

In this way, the sales channel storage section 13 and the sales channel storage control section 14 constitute storage means, which stores and holds the selection signal for a predetermined period of time.

Reference numeral 20 denotes the aforementioned selection price control section, and the control section includes AND circuits A1 . A2 +A3 is provided, and the AND circuit A1. Each terminal of A2 and A3 receives a set price S from the price setting section 18.
P1 to SP3 are applied, and the selection signal output from each corresponding selection switch 19 is applied to the other terminal via the output elements Q1 to Q3 of the sales channel storage section 13. be.

Therefore, the selection signal generated when a customer or the like presses a desired selection switch is stored in the sales channel storage section 13, for example.
If it is output from QI to the above-mentioned AND circuit A1, then
Since it is possible to perform a logical product with SPl that has already been applied to the AND circuit A1, the AND circuit A1 performs a logical product with the price of the product column, that is, SP, to the OR circuit 2.
1 to a sales output determining section (not shown) in the coin sorting device 12.

Reference numeral 22 designates a product delivery drive unit which has seven drive motors installed at the bottom of each product column and discharges the products in each column to a predetermined product outlet.

The driving section 22 is configured such that an AND circuit 23 can perform an AND operation between the sales signal VND from the sales output determining section (not shown) and the selection switch (selection signal) pressed above. Driven when a self-holding circuit is formed.

Therefore, the drive section of the column sends the bend start signal vS to the OR circuit 24, assuming that it has started discharging the product desired by the customer.
The signal is configured to be outputted to the arithmetic control section in the coin sorting device 12 and the sales channel storage control sound β14, respectively, via the above-mentioned coin sorting device 12.

In such a configuration, the present invention will be explained in detail with reference to FIG. ) is stored in the addition/subtraction storage device.

It goes without saying that these stored contents are controlled by timing pulses that are sequentially and repeatedly generated by the transfer pulse generator TR consisting of the well-known multi-by-break mentioned above. It is also used for writing in the sales channel storage control section 14.

That is, the sales channel storage control unit 14 has a length that applies the pulse output from the aforementioned transfer pulse generator TR to one terminal of the AND circuit provided therein.
D circuit circuit - AND output is sent to the channel storage section 1.
It will be output to the CP section of No.3.

This is because the signals Q1 to Q3 are applied to one terminal of the AND circuit from the output elements of the sales channel storage section 13 via the OR circuit x and the inverter, respectively.

Therefore, as described above, by applying the pulse of the transfer pulse generator TR to one terminal of the AND circuit, output to the CP section of the channel register/unique section 13 becomes possible.

Furthermore, the pulses from the transfer pulse generator TR are simultaneously applied to other AND circuit ports, which will be described later.

When a customer or the like presses the selection button 19 of a desired product column in such a state, the selection signal generated by the press and the CP
Since it is possible to synchronize with the clock pulse marked 7JO in the sales channel storage section 13, if we assume that the output is Q1 from the output elements Q1 to Q3 of the sales channel storage section 13, then Ql.
A synchronization signal carrying a selection signal is sent to the AND circuit A1 of the selected price control section 20 corresponding to the above, and to the delay flip-flop DFF (A) of the sales channel storage control section 14 via the transmission line M, and further to the AND circuit 23, which will be described later. This will output the following.

Therefore, in the AND circuit AI, since SPl has already been applied from the price setting section 18, AN with SPl is applied.
When the D output is outputted to the sales output determination section mentioned above through the OR circuit 21, the determination section starts comparing this SP with the memory, that is, the total input amount, which has already been applied from the addition/subtraction storage device. If the determination unit determines that the coin can be sold through the determination operation, the coin sorting device sends the sales signal VND to the product column corresponding to the selected suppression switch via the transmission line N. The AND circuit 23 and the sales channel storage control unit 14 are applied.

Therefore, in the A and N D circuits 23, when the selection switch is pressed, the Q1 output is already applied from the sales channel storage section 13 via the transmission line M, so the product delivery 1 drive mode of the product delivery 1 drive section 22 is activated. starts discharging the products based on the output of the AND circuit 23 mentioned above.

Therefore, this drive morph outputs the bend start signal S to the appropriate device section in the coin sorting device 12 via the OR circuit 24, so that the bend start signal S is output from the original memory content stored in the addition/subtraction storage device, that is, the content stored when the coin was inserted. The length of the product discharged to the product outlet will be subtracted.

If the vending machine is equipped with an amount display or the like, it goes without saying that the arithmetic and control unit will output a reduction command to display the remaining amount after the reduction.

Furthermore, the flip-flop FF (C) in the sales channel storage control unit 14 is initially set to
Since the state reset by the S signal is maintained, the corresponding F
F(C) continues to output the output C to the other terminal of the AND circuit in the sales channel storage control section 14.

Therefore, since the AND circuit port is capable of AND outputting the aforementioned TR signal, it continues to output the AND output to the CP portions of the delay flip-flops DFF(A) and (B).

At this time, DFF prisoner and (B) are sales channel storage unit 1.
Since, for example, Ql, etc. are not applied from the output element No. 3, the outputs Qa and Qb of DFFs (A) and (B), respectively.
is in the state of 0''.

However, when the above-mentioned Q1 signal is applied from the output element of the sales channel storage section 13 to the Da of the DFF (A) via the transmission line M, the clock pulse that has been applied to the CP section from before causes the DFF (5) to The output immediately becomes Qa=1.

However, since the outputs of these DFFs (A) and (B) are each delayed by 1 bit, the output of DFF (B) remains in the state of Qb=O.

In this state, when the VND signal is applied to the set terminal S of the FF (C) through the transmission line N, the FF (C) is applied to the set terminal S of the FF (C).
The output terminal of C) is 6, so the output of FF (C) is Q=
becomes 0.

Therefore, since DFF(A) and (B) cannot be ANDed with TR at the AND circuit port mentioned above, each DFF(A)
.

The output of (B) maintains the state of Qa=1 and Qb=0.

This means that the memory in the sales channel memory unit 13 (the memory of the pressed selection switch) remains latched without being reset.

However, since the drive mode 7 of the product delivery 1 drive unit 22 stops outputting the vS signal outputted when forming the self-holding circuit when the self-holding ends, the FF(C) is activated when the signal falls.
Since output head -1 can be output to the AND circuit port, the above-mentioned DFFs (A) and (B) output Qa=0 and Qb, respectively.
-1, and the memory Q1 of the sales channel memory unit 13, which was latched as described above, is reset.

Therefore, the vending machine is in a standby state for the next product sale.

As described in detail above, according to the present invention, it is possible to provide the same judgment results as conventional coin sorting devices without having to provide a plurality of sales output judgment sections in the coin sorting device as in the past. You can get it.

Furthermore, since the selection price control section and the price setting section are not provided on the coin sorting device side, but are placed in the control box on the main body side, etc., when increasing the number of prices, etc., it is necessary to sort coins as before. It is possible to increase the number of price tags by doing work inside the control box without changing the entire device, so the manufacturing cost is low, and the construction cost when changing the number of price tags is low, so it is automatic. It is possible to provide a very cheap vending control system for vending machines.
