Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a thin automatic ball lending machine that lends out pachinko balls, and more specifically relates to a coin sorting mechanism provided inside the automatic ball lending machine.

(Prior art) In the recent pachinko industry, there is a tendency to centrally control the supply and collection of pachinko balls and coins.
Ball lending machines are also thinner machines that are installed between pachinko machines, and their main purpose is to save labor on the parlor side and provide customer service. Conventional ball lending machines only accepted 100 yen coins as coins, and there were no machines that accepted 500 yen coins. In other words, it was called a coin identification device, and had the function of allowing coins to be returned even if they were valid coins other than 100 yen.

(Problem to be solved by the invention) However, since 500 yen coins are in circulation, there has been a desire for an automatic ball lending machine that can also be used in game halls, but the coin identification device installed in the conventional automatic ball lending machine has only 100 yen coins. Coins other than yen could not be typed or identified.

In order to make it possible to use coins other than 100 yen, this invention is a new coin identification device that can identify whether a coin is appropriate or not, as well as the coin type (100 yen or 500 yen), in place of the conventional coin identification device. The system uses an identification device to convert the signal into an electrical signal, which is then processed by the CPU.It is an automatic coin lending system that is equipped with a coin sorting mechanism that separates coins into a path for valid coins and a path for invalid coins, which was not available in the past. The purpose is to provide an opportunity.

(Means for Solving the Problems) In order to achieve the above object, the coin sorting mechanism of the automatic coin lending machine of the present invention includes a coin identification device that identifies the type or authenticity of the inserted coin, and a coin identification device that identifies the type or authenticity of the inserted coin. comprising a ball rental counting mechanism that operates according to the device, and means for controlling the number of times the ball rental counting mechanism operates,
A coin passage is provided connected to the coin identification device, and the coin passage is formed by a coin return passage directly below the branch part and a coin delivery passage branched in the middle. It consists of a coin sorting plate that can be switched by selecting either the coin sorting plate that guides the coins to the coin return path by demagnetizing the coins, and a branching sensor that detects the coins on the coin sorting plate. If the coin sorting processing means recognizes a proper coin through the coin identification device, the branch solenoid is energized, the coin sorting plate protrudes, the coin is rolled into the coin sending passage, and the coin is moored. At the same time as the release, the payout counting mechanism operates a predetermined number of times depending on the type of coin, and if the above coin identification device identifies an incorrect coin, the branch solenoid is not energized and the coin is dropped from the coin return path to the coin return slot. It is structured as follows.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1A is a side view showing the general layout of the automatic ball lending machine according to the present invention, and FIG. 1B is a front view of FIG. 1A.

The automatic ball lending machine A of the present invention has pachinko balls arranged in a line in a ball passage 1 from a ball supply source (not shown).
The coins are guided, fall vertically in series, and are lent out via the lent ball counting mechanism 2 from the ball outlet 11 opened at the lower end according to the inserted coin (type).

Reference numeral 2 denotes a ball rental counting mechanism, which is provided above the ball passage 1, into which a part of the outer periphery of a sprocket wheel 21 inside the mechanism is inserted. The sprocket wheel 21 has a predetermined number (for example, 10) of concave teeth 21a corresponding to the radius of the pachinko ball P,
The falling pachinko balls P sequentially engage the concave teeth 21a starting from the tip and rotate by their own weight, and when the counting gear 22 that is linked to this rotates once, a predetermined number of pachinko balls P pass. It's becoming like that.

3 is a continuous coin insertion mechanism, in which the first coin S ₁ inserted from the coin insertion slot 30 opened on the front rolls in an inclined coin alignment passageway long enough to moor a plurality of coins, and then passes through a sequential feed lever 31.

The coin S ₁ ″, which is identified as an inappropriate coin by the coin identification device 4, is returned as it is to the coin return port 42 that opens in the front via the coin return passage 41, and at this time, the branch solenoid 51 of the coin sorting mechanism 5 is energized. Therefore, the ball rental counting mechanism 2 does not operate.

Next, when the coin identification device 4 identifies the coin as a proper coin, the branch solenoid 5 of the coin sorting mechanism 5
1 is excited and the coin sorting plate 52 is opened at the opening 5.
The coin S ₁ ' that protrudes from the slot 4 and falls to block the passage rolls along the inclined coin distribution plate 52 and is temporarily moored at the corner of the end.

An elongated hole-shaped opening 54 slightly inclined backward is bored in the wall surface of the branching part 55, and the branching solenoid 5
The tip of the coin sorting plate 52, which is attracted by the first excitation, protrudes and is closed.

53 is a branch sensor and coin distribution plate 52
The coin S ₁ ′, which is unmoored by the detection signal of the coin S 1 ′ moored at the coin S ₁ ′, is sent out falling to the coin sending passage 43 side and collected by a coin conveying device (not shown). The above is the explanation of the coin distribution processing means which is the gist of the present invention.

A governor 28 prevents the sprocket wheel 21 from rotating in reverse.

Next, the operation of the ball rental counting mechanism 2 will be explained.

When the ball-cutting solenoid 26 is energized, the plunger 26a rotates around the shaft 25c of the stop lever 25, and the stop pawl 25 engaged with the catch portion 23a is rotated.
a is tripped against the biasing force of the spring 25d, the restraint of the count gear 22 is released, and the pachinko ball P engaged with the gear 21a of the sprocket wheel 21 is released.
Counting gear 2 via transmission gear 21b with a weight of
2 starts rotating (see Figure 3A). The switch cam 24, which rotates at the same time, turns on at about 1/3 rotation to demagnetize the ball cutting solenoid 26, and the counting gear 22 engages the stop claw 25a with the latch part 23a in one rotation, completing one cycle of counting the paid balls. (See Figure 3B).

If the stop lever 25 is activated for some reason (including unauthorized means from outside), the stop lever 25 is activated by the stop lever 25 due to the cut-off solenoid 26, cut-off switch 27, or other mechanical parts located on the trajectory of the locking part 23a. A blocking claw 25b for preventing over-rotation engages with the hook 23a to prevent abnormal discharge of pachinko balls (see Fig. 3C).

The tip of the progressive lever 31 is pushed up using the top 71a as a fulcrum to anchor the coin _S1 to the first protrusion 31a, and is biased by a spring 72 in a direction in which it pops out to the front of the coin return button 7.

Next, the operation of the coin continuous insertion mechanism 3 will be explained.

The first inserted coin S ₁ rolls in the coin alignment path and is temporarily moored by the first protrusion 31 a at the tip of the progressive feed lever 31 , and is moved to the progressive feed sensor 33 .
When the progressive solenoid 32 is energized by the detection signal of coin S ₁ , the plunger 3 of the progressive solenoid 32
2a is a coin S ₁ that rotates around the support shaft 31d of the forward feed lever 31 and is moored by the first protrusion 31a.
The mooring is released and it falls. Next coin S ₂
is prevented from falling continuously while remaining moored by the second protrusion 31b. This state is coin S ₁
It is maintained until the operation is completed (see Fig. 5).

That is, when the coin S ₁ receives a detection signal from the branch sensor 53 and the forward feed solenoid 32 is demagnetized, the next coin S ₂ moves from the second protrusion 31b to the first protrusion 31.
It is moored to a and starts intermittently from the next operation of the continuous coin insertion mechanism 3.

When the coin return button 7 is pressed, the coin return lever 71 rotates around its top 71a, lowers the tip of the progressive lever 31, releases the coin from the first protrusion 31a, and returns the coin to the coin return slot 42. (See Figure 6).

It is also equipped with a clock as a control timing signal and a timing clock such as a dynamic display to ensure reliable digital operation.

FIG. 9 and FIGS. 10A to 10C are a flowchart and a timing chart showing the operation and functions of the entire apparatus, and the following description will be made based on the flowchart with reference to the timing chart.

If a trouble message such as "stop use" is displayed on the front display section 8, coin insertion is not possible (steps n101 to n103). In step n104, while the forward feed sensor 33 is on, if the inserted coin _S1 is on the first protrusion 31a and no other switch (for example, the ball rental is out of supply) is on, the CPU 61 determines that it is on. The forward feed solenoid 32 is turned on after 0.5 seconds (steps n105 and n106). If the coin _S1 inserted here is a fake coin, the forward feed solenoid 32
It turns on and after 2 seconds it turns off and returns and a trouble message is displayed. In step n107, the coin identification device 4 identifies the appropriate/inappropriate coin and its type (in this example, a 100 yen or 500 yen coin), and determines an inappropriate coin S ₁ ″ (a coin other than 100 yen or 500 yen coin). If so, proceed to step n108, the coin will be returned, and the coin will become a valid coin.
_S1 ' turns on the branch solenoid 51, closes the coin passage 40 with the coin sorting plate 52, and is detected by the branch sensor 53 (steps n109 to n110).
If no detection signal is output after 3 seconds in step n110, a trouble message will be displayed (step n111).
~n112). In step n113, the type of coin is displayed as a code, and the process moves to step n114, in which the coins are counted.
Here, the branch sensor 53 is turned on, and the mooring of the coin S ₁ ' is released, and the ball cutter solenoid 26 is turned on with the off signal, and the counting of paid balls of 100 yen/time is started (step n115). Moving to step n116, when the ball cutting switch 27 is turned on, the ball cutting solenoid 26 is turned off.
After completing the counting of 100 balls per cycle (step n119), the display shows the number with 1 subtracted (step n121). You are asked to finish at step n122, but if the remaining display is other than 0, then step
Branching to step n115, the ball rental count is repeated, and when the remaining display becomes 0, the process returns to the starting position and waits (step n101). Steps n117 and n120 flash and display a trouble code when the balls are out of stock.

Immediately after the sequential feed sensor 33 detects coin S ₁ and the sequential feed solenoid 32 is turned on, the sequential feed sensor 3
3 is turned off, but the forward feed solenoid 32 is turned off by the off signal of the cutter switch 27. In other words, the signal identified as 500 yen by the coin identification device 4 is sent to the CPU 6.
The sequential feed solenoid 32 remains on until the fifth turn-off signal of the cut-off switch 27 after the calculation is performed in step 1.

After the branch sensor 53 is turned off, the amount displayed is ``5'' or ``1'' according to the input amount, and after the cutoff switch 27 is turned off, it is subtracted (-1).

If an abnormality occurs in the operating sequence, all functions will stop.

(Effect of the invention) This invention can be applied to coins other than 100 yen (in this example,
Equipped with a coin identification device that identifies or types coins (2 types (100 yen and 500 yen)) and whether the coins are appropriate or inappropriate, coins other than 100 yen can only be used with this function, and incorrect coins cannot be used. If the correct coin is ejected, the payout counting mechanism is activated by the detection signal of the branch sensor, and the payout counting mechanism is accurately counted according to the type of coin, completely preventing fraudulent means from outside, and furthermore, turning off the branch sensor. The signal is sent to the CPU to turn off the sequential feed solenoid, move the next coin to the first protrusion, and standby for the next operation.
The effect of the coin sorting mechanism of the automatic ball lending machine, which is configured to perform arithmetic processing, is enormous.
