Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a change auxiliary device such as a vending machine for dispensing necessary change when selling products in a vending machine instead of a vending machine.

There are two types of change auxiliary devices: a type that replenishes the rectangular number of coins into the coin tube when there is insufficient change in the coin tube of the coin mechanism, and a type that directly dispenses coins as change. , related to the type that directly pays out money.

Conventionally, in the method of directly dispensing change, the coins in the three tubes (generally there are three tubes) in the change auxiliary device are accurately and reliably removed one by one according to the dispensing request signal from the coin mechanism. A mechanism for dispensing coins is required, and for this reason, conventional systems are generally more complex in mechanical structure than those that simply replenish a fixed number of coins into a tube of a coin mechanism, and are therefore expensive. There is.

゛The present invention has a simple mechanical structure equivalent to a type of change auxiliary device that replenishes a fixed number of coins into the tube of the coin mechanism every time a change iron shortage signal is given, and a type that directly dispenses change to the customer in the required number of coins ( The purpose is to provide a change auxiliary device (hereinafter referred to as a direct dispensing type). The present invention will be explained below with reference to the embodiments shown in the drawings.

As shown in FIG. 1, the motor a rotates in response to a payout signal from the coin mechanism, and the rotation is transmitted to the drive discs S, B, through reduction gears.

Drive disk b1 eb20 rotation slides drive plate C in the direction of arrow
m and d3 are engaged with coin dispensing slide plates el+e21e3 built into each of the three tubes.

Therefore, the driving disk b! , b2 rotate once each, the drive plate C reciprocates once, so the slide plate @ or e3
also makes one round trip, and during that time, one from each of the three tubes.
Drop a total of 3 coins into the aisle. At this time, a gear system is provided so that the cam of the microswitch part also rotates once when each of the drive discs b1 and eb2 rotates once, and the motor power is switched to the microswitch every time the drive discs b1 and eb2 rotate once. Make sure to turn it off.

The following explanation will be given in Fig. 2. Of the three coins dropped into this passage p, the coin A closest to the exit is ejected from the exit as change, and the remaining two coins B and C are St, par f, g connected to a solenoid installed in the passage
is held in When the coin A dispensed here as change passes through the exit, the sensor h provided at the exit detects the discharge and sends a signal to the coin mechanism.

Furthermore, when change is requested from the coin mechanism, the stopper solenoid blocking the coins in the passage is turned on, the stopper f is retracted, the passage opens, and the coin B is dispensed as change. At this time, the sensor h at the exit detects the payout and sends a signal to the coin mechanism.If the next change is required, the stoppers f and g connected to the solenoid are simultaneously turned ON by the signal from the coin mechanism. The passage opens and coin C
is paid out.

At this time, similarly to the above, a signal is sent from the exit sensor h to the coin mechanism, and signal communication continues until the required number of change is reached.

If you need change for the fourth coin or later, just like the first time, drive disks bl+b2 rotate once due to the rotation of motor a, drop three coins from the tube into the passage, and repeat the process of paying out only one of them. The action is performed.

As described above, according to the present invention, the following excellent effects can be obtained.

(1) A direct payout type change auxiliary device can be provided with a simple structure similar to a change auxiliary device that replenishes to a coin tube.

(2) Since the component parts of the direct payout type and the coin tube replenishment type can be widely used in common, manufacturing is extremely convenient and production costs can be reduced.

Claims (2)

[Claims] (1) When coins in a coin mechanism equipped with an out-of-change detection sensor in a vending machine become insufficient, change necessary for selling the product stored in the vending machine is provided by a signal from the coin mechanism. A change auxiliary device for an automatic vending machine, etc., which dispenses change in place of the coin mechanism. (2) When a change payout signal is received from the coin mechanism, a means is driven by a motor to push out one coin from each of the three change tubes into the passageway, and a means for pushing out one coin from each of the three change tubes into the passageway, and a coin closest to the exit out of the three pushed out coins. means for ejecting the coins directly to the outside of the exit; means for detecting the ejection and sending a detection signal to the coin mechanism; and a stopper for holding the coins in the passage within the passage. After the coin closest to the exit is ejected, one solenoid operates to eject one coin on the path in response to the next coin dispensing signal, ejects one coin, and then dispenses change. When it is necessary to pay out change, two solenoids operate to eject the last coin on the path, and when it is necessary to pay out change, the motor rotates to eject the last three coins from the path as before. Push it out and use the change auxiliary device for the other person.
