Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin processing device for a vending machine, and more particularly to a coin processing device for determining the start point of energization of a gate control solenoid of a coin passage in a coin sorting device.

[0002]

2. Description of the Related Art A coin processing device of this type is shown in FIG.
The configuration is as shown in (a) and (b). That is, the coin X inserted from the coin insertion opening falls on the first rail 2 provided obliquely. And this first rail 2
It rolls over and passes through the coin testing section 3.

The coin test section 3 applies an electromagnetic field to a coin to inspect the material and dimensions, and outputs the inspection result to a determination device (not shown). The determination device determines the authenticity and type of coins according to the inspection result signal from the coin test unit 3,
Form signals for coin handling and merchandise sales.

The contents of the processing of coins are false coins, or even if they are genuine coins, they can be returned when a prohibition signal for coins is issued, such as when the change cannot be covered by the main body control unit at that time. Yes, the first solenoid 5 is deenergized, and the first gate 4 is moved to the position shown in the drawing to guide the inserted coin X into the return passage. In another coin processing, the operation control of the second solenoid 8 is performed by determining whether the input coin X is guided to the change tube passage 14 or the cash box passage 9 according to the change accumulation state in the change tube 11. Is to do
The determination device urges and deactivates the second solenoid 8 according to the inspection result of the coin test unit 3, and determines the passage through which the inserted coin X should pass.

For product sales, the determination unit calculates the amount of money by the coin type as the inspection result of the coin test unit 3 and the number of coins by the pass sensor 6, subtracts the product price to obtain change, and sells the product and sends the change. Form and send out a signal for.

Thus, the coin processing in the coin processing device is performed.

As the above-mentioned conventional technique, US Pat.
No. 06,610 and Japanese Patent Publication No. 59-43798.

As shown in FIG. 4, the coin passage is constructed by combining two oblique passages so as to face opposite to each other. Then, the coins passing through the first gate 4 and then out of the pass sensor 6 toward the change tube passage 14 are redirected by the second gate 7 to be guided to the second rail 10 and stored in each change tube. Has become.
The second gate 7 is opened and closed by turning on and off the second solenoid 8.

[0009]

FIG. 5 is a timing chart of signals at various parts of the circuit including the second solenoid signal, which are generated in the circuit for operating the device of FIG. 4, and the delay occurs after the coin X passes through the pass sensor 6. It indicates that the timer is deenergized after a predetermined time set in advance has elapsed.

Here, the second solenoid signal rises in accordance with the rise of the true coin signal, and falls after a predetermined time has passed after passing the pass sensor 6, but the time until it falls is the behavior in the middle of the coin X. Fluctuates under the influence of and is indefinite.

For this reason, the second solenoid 8 sometimes becomes overheated due to a long energization time.

The present invention has been made in consideration of the above points, and the energization time of the second solenoid provided in the second gate for sending out coins determined to be genuine coins to the passage for the cash box or the change tube becomes longer. It is an object of the present invention to provide a coin processing device that determines the start time of energization so as not to pass.

[0013]

In order to achieve this object, in the present invention, an electromagnetic test is performed on the material and size by a coin test section while allowing a coin inserted from a coin slot to pass through a predetermined passage. And a first solenoid that operates the first passage switching mechanism according to the result of the acceptance determination to send the inserted coin to the passages for the true coin and the false coin, and for the true coin, a path sensor provided in the passage. To detect the passage of coins, and then activate the second solenoid that activates the second passage switching mechanism according to the type of coins obtained as a result of the above test, thereby activating either the passage to the cash box or the passage for the change tube. In the coin processing device, which sends the true coins to the change tube and separates and distributes the coins into the different tube paths for each type of coin in the change tube path, There is provided a coin processing device, comprising a solenoid energizing circuit for starting energization of the second solenoid upon rising of a signal and ending energization after a lapse of a predetermined time from the fall of the detection signal of the pass sensor. It is a thing.

[0014]

The path sensor is provided between the first passage switching mechanism and the second passage switching mechanism, and outputs a signal when the passage of the true coin is detected. In response to this output, the solenoid energizing circuit energizes the second solenoid to actuate the second passage switching mechanism to send the true coin into the change tube passage.

Then, when sufficient time has passed for the true coin to be guided to the change tube, the solenoid energizing circuit
The urging of the second solenoid is terminated and the second passage switching mechanism is returned to the original state.

When the inserted coin does not pass the pass sensor even though it passes through the first passage switching mechanism, the second solenoid is not energized, and the second solenoid is not energized for a long time.

[0017]

As described above, according to the present invention, since the second solenoid is activated only after the inserted coin determined to be a true coin reaches the pass sensor, the inserted coin as generated by the conventional device does not easily become the pass sensor. If the second solenoid is not reached, the second solenoid is not energized for a very long time, and overheating and burning of the second solenoid can be prevented.

[0018]

1 (a) and 1 (b) show the construction of a front view of a coin processing apparatus and a conceptual view of a coin passage showing an embodiment of the present invention. The target mechanism of this embodiment is similar to that shown in FIG. In this embodiment, the target coins are US coins of $ 1,25 ¢, 10.
The case of ¢ 5 ¢ is shown. Therefore, three change tubes 11 for 25, 10, and 5 are provided, while the $ 1 coin is directly accommodated in the cash box. FIG. 2 is a block diagram showing the circuit configuration of FIG.

The circuit shown in FIG. 2 includes a signal from the coin test section 3 constituted by the selection coil 3A and the discrimination circuit 3B, a coin detection signal from the pass sensor 6, and an excess or deficiency of change from the overflow sensor 12 and the empty sensor 13. Signals are given to the CPU 15, and the CPU 15 performs an operation based on these signals to perform an operation for processing coins and selling goods.

Although not shown in FIG. 1, the empty sensor 13 is provided below the change tube 11. Here, only the signal paths for operating the first solenoid 5 and the second solenoid 8 are shown, and the signal paths for selling products are not shown.

Although not shown in the figure, an inventory switch for paying out the change is connected to the CPU 15, and coins of a desired type are paid out from the change tube in accordance with the operation of the inventory switch.

FIG. 3 is a timing chart showing signals of various parts of the circuit shown in FIG. What should be particularly noted in FIG. 3 is that the second solenoid signal rises along with the rise of the pass sensor signal. That is,
Only when the pass sensor 6 (FIG. 1) detects the passage of the coin determined to be a true coin, the second solenoid is energized and sent to the change tube passage.

Next, the operation after the coins X have been inserted through the insertion slot 1 will be sequentially described with reference to the timing chart of FIG. Here, it is assumed that no coin acceptance prohibition signal is output from the vending machine body, and neither overflow sensor of the change tube detects the fullness of coins.

First, when the inserted coin X is tested by the coin testing unit 3 and is determined to be a true coin, the coin testing unit 3
A genuine coin signal is given from the CPU 15 to the CPU 15. CPU
In the drive circuit 15, the drive circuit 16 forms a first solenoid signal based on the true coin signal to operate the first solenoid 5. As a result, the first solenoid 5 is biased for a short time, and the first gate 4 is connected to the true coin passage. The operation for determining the type of the true coin here is 25, 10 and 5 coins excluding the $ 1 coin directly stored in the cash box. For a $ 1 coin, the first solenoid 5
Only operated and stored directly in the cash box.

Next, when the inserted coin X approaches the position of the pass sensor 6, the pass sensor 6 forms a pass sensor signal. The CPU 15 obtains this pass sensor signal and knows that one coin has passed. The signal about the type of coin is
Since it has already been given from the coin testing unit 3, the CPU 1
5 can know the amount of money at this point.

On the other hand, in response to the pass sensor signal, the CPU 15 operates the drive circuit 17 to form the second solenoid signal, and starts energizing the second solenoid 8. Next, the pass sensor 6 causes the pass sensor signal to disappear by the passage of the coin.
At this time, the CPU 15 is caused by the fall of the pass sensor signal.
The delay timer incorporated in the drive circuit is activated to give the drive circuit 17 a signal that lasts for a predetermined time. Therefore, the drive circuit 17 continues to energize the solenoid 8. And
After the elapse of a predetermined time, the second solenoid signal from the drive circuit 17 is caused to fall.

As a result, the duration of the second solenoid signal becomes a signal that lasts for the duration of the path sensor signal plus the predetermined time set in the delay timer.
Therefore, the second solenoid 8 is not energized indiscriminately for a long time, and overheating and burning due to long-time energization are not caused.
