Abstract

PURPOSE:To prevent burning without enlarging the rating of a change paying device and without stopping it automatically by driving it so that a duty ratio may become smaller after paying actions more than a storable number. CONSTITUTION:The title controller is equipped with a driving control means 1 to drive a change paying device so that the duty ratio may become smaller after a count value reaches a prescribed value than before based on the comparison result of a comparing means to compare the count value of a counting means 11 with the prescribed value more than the coin storable number of the change paying device. Thus, until it reaches the prescribed value, it is driven at the duty ratio sufficient for paying change and after it reaches the prescribed value, it is driven at the sufficiently small duty ratio, thus, even when the rating of the change paying device is the one which can bear the paying actions of the storable number, the drive is not stopped and the burning can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a change collection control device for a vending machine, and particularly to a change dispensing device that protects a change dispensing device during change collection.

[Conventional technology]

As described in Japanese Utility Model Application Publication No. 55-86266, this type of change collection switch is an automatic return type (so-called push button type) that commands the collection of change, and a change collection switch based on the operation of the switch. A detection device is provided to detect coins dispensed by the driven change dispensing device, and the change dispensing device is driven when no detection output is generated from the detection device within a predetermined time (that is, when all coins have been dispensed). It is known what made it stop.

[Problem to be solved by the invention]

By using a push-button type switch as the change collection switch to automatically stop the change collection, the change dispenser will not be left running unnecessarily even if you forget to stop the collection. etc., and is very effective for protecting the change dispensing device.

However, when a push-button type switch is used as the change collection switch, the switch automatically returns to its original state after being operated, so it is not possible to visually confirm the operating state of the switch. For this reason, when collecting change by specifying one of multiple change cylinders, it is difficult to tell which change cylinder is currently being collected by looking at the change collection switch. There is an inconvenience.

In order to eliminate this inconvenience, a slide switch can be used as the change collection switch, but if the slide switch is used to perform the automatic stop as described above, the change collection switch remains operated. In this state, the change dispensing device is stopped, and the state commanded by the change collection switch and the state of the change dispensing device do not match, and there is a risk that it may be mistaken for a malfunction.

Of course, if you use a solenoid with a sufficiently high rating for the drive solenoid of the change dispenser (i.e., if you use a large external one with thick windings to reduce temperature rise), it will not stop automatically. There is no problem with this, but as long as you don't forget to turn off the change collection switch, you can just make it withstand the operation of dispensing all the stored coins, which unnecessarily increases the size and cost, making it uneconomical. There is the problem of becoming something.

In view of the above-mentioned points, an object of the present invention is to provide a change collection control device for a vending machine that can prevent burnout without increasing the rating of the change dispensing device and without automatically stopping the change dispensing device. shall be.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a counting means for counting the number of times a change dispensing device dispenses one coin while a change collection switch is operated, and a count value of the counting means and change. a comparison means for comparing a predetermined value greater than or equal to the number of coins that can be stored in the dispensing device, and based on the comparison result of the comparison means, the deity ratio is higher after the counted value reaches the predetermined value than before it reaches the predetermined value. The present invention is characterized by comprising a drive control means for driving the change dispensing device so that the change dispensing device is driven.

[Effect]

In the present invention, when the number of change dispensing operations of the change dispensing device reaches a predetermined value equal to or greater than the storable number of coins, the duty ratio is reduced. Therefore, until this predetermined value is reached, the change dispensing device is driven at a duty ratio sufficient for dispensing coins, and after reaching the predetermined value, the stored coins have been dispensed, so the change dispensing device can operate. By driving at a sufficiently small duty ratio within the range, even if the rating of the change dispensing device is such that it can withstand the operation of dispensing as many coins as it can store, burnout can be prevented without stopping the drive.

〔Example〕

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.
1 is a control device using a microcomputer, 2 is a change collection switch composed of a slide switch, and 3 is a change dispensing device. Here, the change dispensing device 3 is provided with four change cylinders (not shown), and if these change cylinders are designated as A, B, C, and D, then the coins in the change cylinder A are driven to be dispensed. It is the driving lenoid S, and the change cylinder B.
, C, and D is a drive motor M, and 31 is a carrier switch that is turned ON and OFF in synchronization with the operation of the drive motor M to dispense one coin.

Then, when driving the drive motor M, the change tubes B and C

Positions A, B, and C corresponding to .

By sliding it to D, a change collection command for each change cylinder is given to the control device rItl.

Further, the control device 1 is provided with a counter (CT box) 11 and a timer 12. Although these may be provided individually, if a micro converter is used, R
It can be easily configured using AM, etc.

Next, FIG. 2 shows the operation of the apparatus having such a configuration.

This will be explained according to the flowchart of the operating program shown in FIG. 3 and the time chart shown in FIG. In this case, the description will be made assuming that the solenoid S for driving the change cylinder A is one that has a large temperature rise and needs to be protected.

First, the operating program shown in FIG. 2 is activated when the slide piece 21 of the change collection switch 2 is operated to a position other than OFF while the vending machine is in a sales standby state. At this time, the counter 11 is cleared, the timekeeping operation of the timer 12 is stopped, and the timekeeping contents of the timer 12 are cleared.

In step 201, it is determined in which position the slide piece 21 of the change collection switch (inventory switch) 2 is located (that is, which change cylinder among change cylinders A, B, C, and D is commanded to be collected). is determined, and if it is in the OFF position, the change collection operation is finished, the state returns to the sales standby state, and the switch is turned OFF.
If it is at a position other than FF, that position (that is, the change cylinder whose collection has been commanded) is memorized and the process proceeds to step 202. In step 202, the operation of dispensing one coin from the change tube stored in step 201 is performed, and the process proceeds to step 203.

In step 203, the driving solenoid S is driven depending on whether or not the dispensing in step 202 is by driving the driving solenoid S with a large temperature rise (this is determined based on the stored contents in step 201). (i.e., to the change tube), the process proceeds to step 204;
Otherwise, the process proceeds to step 205.

In step 204, the contents of the counter 11 are changed to a predetermined number of times N.
If it is the predetermined number N or more, the timer 12 starts counting, and in step 208, the timer 12 waits until the predetermined time Ams has been counted, and returns to step 201. If it is small, step 20
At step 7, the contents of the counter 11 are incremented by 1 and the process returns to step 201. Further, in step 205 (that is, in the case of dispensing money other than the change tube A), the contents of the counter 11 are cleared and the process returns to step 201.

After the timer 12 has counted the predetermined time Am s at step 208, the timer 12 stops counting and the timing contents are cleared (0) Next, FIG. 202 shows the details of step 202. First, in step 301, start timer 12 to measure time, wait until timer 12 measures Bmi for a predetermined time in step 301, and when it measures Bms, clear the timing contents ( The timing operation continues as is) and the process proceeds to step 302. In step 302, step 302 is performed.

Based on the stored contents in the change cylinder 201 (FIG. 2), it is determined whether a command has been given to dispense or collect the change from the change cylinder A, and whether the change cylinder is to be dispensed by driving the drive solenoid S or not. If it is not the change tube A, proceed to step 305. In step 303, it is determined whether the content of the counter 11 is equal to or greater than a predetermined number N. If the content is equal to or greater than the predetermined number N, the process proceeds to step 304, and if it is smaller than the predetermined number N, the process proceeds to step 305. move on. In step 304, it is determined whether or not the timer has clocked a predetermined time Cms. If the timer has clocked, the process proceeds to step 306; if not, the process proceeds to step 307. In step 305, it is determined whether or not the timer has counted a predetermined time Dms. If the time has been counted, the process proceeds to step 306; if not, the process proceeds to step 307. In Step 307, a load is driven according to the contents stored in Step 201 (Figure 22) (that is, if change is to be dispensed from the change tube A, the drive solenoid S is driven, and the change is dispensed from the change tube B. If so, drive motor M and switching solenoid C81, and if change is to be dispensed from cylinder C, drive motor M and switching solenoid C81.
Step 3
Return to 02. Further, in step 306, the timer 12 stops the time measurement operation, clears the time measurement contents, and
At step 307, the drive of the load subjected to JIA operation is stopped (if this load is the drive motor M, the operation is confirmed by the signal from the carrier switch 31), and the process ends.

By executing the operation program as described above, the administrator of the vending machine can press the slide piece 2 of the change collection switch 2.
1 to the person in the position to command the payout of coins for change collection, until the number of continuous operations for dispensing one coin reaches a predetermined number of times N-1, step 201→ in FIG.
A loop of 202 → 203 → 204 → 207 → 201 is executed and the number of operations is counted.
The loop is executed and a pause time of a predetermined time Ams is provided. Also, if you slide the slide piece 21 by ζ other than 1zA to command the payout of coins other than the change tube A,
A loop of steps 201→202→203→205→201 is executed and the number of operations (counter 11) is cleared. Same, Ste.

The memory in step 201 (memory of the change cylinder that was commanded to be collected) is as follows.
This is updated every time this step 201 is executed.

In addition, in FIG. 3 (that is, for each dispensing operation of one coin), after a pause of a predetermined time Bms (step 301), in the case of dispensing from the change tube A, the number of operations is the predetermined number N-1.
Until then, the drive solenoid S is driven open for a predetermined time Dms (a loop of steps 302→303→305→307→302), and after the predetermined number of times N, the drive solenoid S is driven open for a predetermined time Cms (step 302). →303→304
→ 307 → 302 loop).

That is, when the command to collect the change cylinder A continues to be issued by operating the change collection switch 2, the drive solenoid S is turned off until the number of continuous operations reaches a predetermined number N-1, as shown in the time chart of FIG. The drive (energization) time is Dms, the g moving body positive time is Bms, and after the predetermined number N, the drive time is Cms and the drive body stop time is A + Bms.

Here, the predetermined number of times N-1 is the coin that can be stored in the change tube (i.e., change tube A) that is dispensed by driving the load that needs to be protected (i.e., the driving coin S) due to the large temperature rise. The predetermined times Dms and Bms are determined so that one coin can be reliably dispensed, and the predetermined time Cms is determined to be as short as possible within the range of understanding the operation of the load. Ams&! for a specified period of time.
, the load (driving solenoid S) is determined so that it can withstand the temperature rise when continuously operated with driving Cms+rest A+Bms. However, 1 hour A-)-B 10 is within a few seconds, and even if the number of operations reaches the predetermined number N, the slide piece 21 of the change collection switch 2 may be in a position other than OFF due to the operating sound of the load drive. It is best to keep this in mind. In addition, the load (drive solenoid S)
Needless to say, a device that can withstand the temperature rise during continuous operation up to a predetermined number of times N-1 is used for the driving time Dms and resting time Bms.

Then, the power consumption of the load (drive solenoid S) is Po
Then, the average power consumption until the number of operations reaches a predetermined number N-1 is PoD7 (1) 10B), but after the predetermined number N, it is reduced to POC/(A+B+C). After the predetermined number of times N, all the stored coins have been dispensed, so it may be a problem to shorten the drive time or lengthen the pause time (even if you do so, it will be difficult to dispense the coins 4 times). There isn't.

In the above-mentioned embodiment, the driving time is shortened and the pause time is lengthened after the number of operations reaches a predetermined number, but only one of them may be performed. In short, the driving duty ratio should be made small after a predetermined number of times.

Furthermore, if the load is a motor, it is not possible to shorten the drive time, so the problem can be dealt with by lengthening the rest time.

〔Effect of the invention〕

According to the present invention as described above, the drive is performed so that the duty ratio becomes small after the operation of dispensing more than the storable number of coins,
Since we have made it possible to prevent burnout without stopping the drive, we use a slide switch as the change collection switch, and even if you forget to stop the collection once, the command state of the switch and the state of the change dispensing device will not match. There is no such inconvenience.

The change dispensing device can be suitably protected.
