Abstract

PURPOSE:To prevent such danger as the hand of a purchaser who takes out a commodity after sales is splashed with hot water, etc., for washing by delaying an output of an actuating signal of a washing time timer by a prescribed time, when a sales signal outputted from a sales control circuit is detected. CONSTITUTION:When a sales signal is detected in the course of counting of an elapsed time timer 1, the timer 1 is cleared, and after sales are finished, counting of an elapsed time is restarted. When the timer 1 becomes count time-up, in accordance with setting of a washing time timer 2, a washing operation is executed by opening and closing a valve 6, and when washing is finished, the machine becomes a regular sales state. In such a way, when a washing start time comes in the course of sales and immediately after sales, washing is not started for a prescribed period, and such danger as a hand of a purchaser who tries to take out a commodity is splashed with hot water, etc., is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic cleaning control device for a beverage vending machine that dispenses beverages into cup containers for sale.

Prior Art In recent years, various automatic cleaning control devices for beverage vending machines have been invented in order to prevent clogging of the beverage dispensing system of expanded vending machines and to keep the beverage dispensing system sanitary. (For example, Japanese Patent Laid-Open No. 51-204799).

This type of automatic cleaning control device for a beverage vending machine includes a door opening/closing detection means for detecting all open/closed states of the door of the vending machine, a cleaning means for cleaning equipment to be cleaned such as passages for products and their raw materials, and a cleaning means for cleaning equipment to be cleaned such as passages for products and their raw materials. cleaning time timer means for outputting a cleaning start signal at time intervals determined by the conditions; and cleaning operation for a predetermined time to the cleaning means based on the cleaning start signal. When the door of the vending machine is open, a detection signal is output from the door opening/closing detection means. Even if a cleaning start signal is output from the timer means to the control means, the automatic cleaning by the cleaning means is suspended, and if the door does not close even after a certain period of time has elapsed, the automatic cleaning is stopped. In addition, when the door opening/closing detection means detects that the door has been opened during the automatic cleaning operation by the cleaning means, the control means can detect that the door has been opened. The automatic cleaning operation can be immediately stopped, making the operator's work easier.

Problems to be Solved by the Invention However, in the above conventional configuration, when the automatic cleaning start time set in the cleaning timer means comes during the sales operation, a cleaning start signal is output from the cleaning timer means to the control means. Since automatic cleaning by the cleaning means starts immediately after the sales operation ends, there is a risk that the hot water etc. discharged from the cleaning means at this time may get on the hands of buyers who try to take out the products after sale. I was aware of my shortcomings.

Means for Solving the Problems In order to solve all of the above problems, the automatic cleaning system of the present invention -) Misakiso@ is equipped with several 3-strong tanks that can hold all the beverages, and is installed in each tank to collect the beverage raw materials and cleaning from the tanks. a beverage supply line through which hot water or water flows; a solenoid valve installed in each beverage supply line to control the pouring of liquid from the beverage supply line;
a first timer for determining the washing time with hot or cold water for each beverage supply line; a second timer for outputting an activation signal for activating the first timer; prohibition means for detecting a sales signal output from a sales control circuit connected between the timers and for controlling beverage sales, and delaying the output of the start signal of the second timer for a certain period of time when the sales signal is detected; and has.

Operation This defense is based on the above structure, which allows the timer to be switched from the second timer to the first timer.
When starting the second timer and outputting the start signal to start the cleaning operation, if the sales signal is being output sideways from the sales control circuit, the output of the start signal of the second timer is delayed for a certain period of time. , Is there a danger in starting the cleaning operation immediately after the sales operation ends? Can be removed.

EXAMPLE Hereinafter, the present invention will be explained in detail using FIGS. 1 and 2.

FIG. 1 is a block diagram showing the main circuit configuration of an embodiment of the present invention, and FIG. 2 is a flowchart explaining the operation of FIG. 1.

In FIG. 1, 1 is an elapsed time timer (cleaning start inhibiting means) that detects the sales signal sent at the start of sales and counts the elapsed time from the end of sales, and 2 is a washing start timer for each beverage supply line. (first timer),
3 is a cleaning start timer (second timer), and 4 is an arithmetic control unit that controls vending and cleaning of the vending machine.

In addition, the cleaning time timer 2 and cleaning start timer 3 are
It can be set in advance using the setting device 5. 6 is a pulp that opens and closes a solenoid valve for hot water or water. From this pulp, hot water for cleaning is supplied to the equipment to be cleaned (from each beverage tank to each beverage supply line) installed in the vending machine body (not shown). Or supply water for cleaning. For cleaning operation, the current time is cleaning start timer 3.
When the time set in is reached, it is determined whether or not the washing start prohibition condition of the elapsed time timer 1 has been cleared, and the pulp 6 is opened and closed according to the washing time timer to perform washing.

The above cleaning operation will be explained with reference to FIG.

First, the cleaning time timer 2 and cleaning start timer 3 are set using the setting device 6 shown in FIG. 1 (step $1).

At this time, the elapsed time timer 1 is set to time up (step S2 people).

After setting timers 2 and 3 above, if the selling operation is not performed until the current time reaches the cleaning start time,
This is because the cleaning starts at the same time as the cleaning start time arrives.

Cleaning time timer 2. After setting the cleaning start timer 3, when a sales operation is performed, the sales start signal is detected (step S3), the elapsed timer 1 is cleared, and after the sales end, counting of elapsed time is started. (Step S4). After that, the counting operation of the elapsed timer 1 is repeated until the current time reaches the cleaning start time (steps S5 and S6). When the current time reaches the start time set in the cleaning start timer 3, (Step Ss), it is determined whether or not the elapsed timer 1 has timed up (step S7), and if the elapsed timer 1 has not timed up, the counting of the elapsed timer 1 is continued until the timed out. However, if there is a sales signal during counting (step Ss), the elapsed time timer 1 is cleared again, and after the sale ends, the elapsed time counting is restarted (step S9). If the count has increased, follow the setting of washing time timer 2 and turn on pulp 6.
Open and close to perform cleaning operations. (Step 51o).

The cleaning operation is continued until the cleaning time timer times up (step 511), and when the cleaning is completed, the routine returns to the regular sales state.

As mentioned above, is the activation of the cleaning operation a sales signal? It is possible to prevent activation of the elapsed time timer 1 for a certain period of time from the end of the final sales operation until the timer reaches the time limit. There is no danger of splashing hot water, etc., and safe sales are possible.

Effects of the Invention As described above, the automatic cleaning control device of the present invention includes several types of tanks for storing beverages, a beverage supply line installed for each tank and through which beverage raw materials and hot or water for washing flow from the tanks, and a beverage A solenoid valve installed in each supply line to control the entire liquid discharge from the beverage supply line, a first timer for determining the intestinal or water irrigation time for each beverage supply line, and a first timer for starting the first timer. a second timer for outputting a start signal; and a sales signal output from a sales control circuit connected between the first timer and the second timer for controlling beverage sales; is detected, the output of the start signal of the second timer is delayed for a certain period of time (kW), and the second timer is switched from the first timer to the first one.
When outputting the start signal to start the timer and start the cleaning operation, if all sales signals output from the k anti-sell control port are detected, the output of the start signal of the second timer is delayed for a certain period of time. By doing this, cleaning will not start for a certain period of time even during the sale or immediately after the sale when the cleaning start time is reached, so there is no risk that the hands of the purchaser who tries to take out the product after the sale will get splashed with cleaning hot water, etc. We can offer you all safe and secure sales.
