Description

[Detailed Description of the Invention] The present invention relates to an automatic pachinko ball lending machine in the form of a vending machine that automatically lends out pachinko balls, and in particular responds to inserted coins only by mechanical means without using any electrical means. This invention relates to an automatic ball rental machine for pachinko that can automatically dispense a predetermined amount of pachinko balls.

Recently, pachinko balls, which are lent out in predetermined quantities at pachinko parlors, are being lent out using pachinko ball rental machines in the form of vending machines, as pachinko parlors are saving labor.

With the trend toward central control of all supply and collection of balls, pachinko ball rental machines have also been incorporated into a series of pachinko ball supply systems, and are installed between pachinko machines when they are installed, saving space and making them easily accessible. Pachinko balls are available for loan at certain locations.

Even for this type of pachinko ball rental machine, the first condition is to accurately dispense the amount of balls according to the coins inserted, and at the same time, it is also required that it always operate accurately and without any failures. be done.

However, in the above-mentioned conventional pachinko ball rental machines, not only the command to dispense pachinko balls after the sorting of the inserted coins is completed, but also the operation of actually dispensing a predetermined number of pachinko balls are performed by electrical means such as electromagnets. As a result, electrical work had to be carried out prior to installing a pachinko ball rental machine.As a result, the manufacturing cost of the pachinko ball rental machine increased, and the installation work of the pachinko machine required the electrical wiring work to be completed. In view of this, the present invention has been developed to provide an automatic ball dispensing machine for pachinko. The ball discharging mechanism is constructed by pure mechanical means,
Automatic balls for pachinko that can start operating as soon as they are installed in a store, and can provide the ball rental machine itself at a low price, while at the same time simplifying the installation work in the store and drastically shortening the installation work. This was done for the purpose of providing rental machines.

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

The overall configuration of the automatic pachinko ball lending machine according to the present invention is as follows:
As partially shown in the figure, there are a pachinko ball passage 2 and a coin passage 3 in the upper part of the rectangular and thin box-shaped machine body 1, and a coin C inserted through the coin passage 3.
A coin sorting machine 4 that determines the suitability of coins and takes them in if they are proper coins and returns them if they are fraudulent; and a pachinko ball dispenser that dispenses a predetermined amount of pachinko balls using coin C when the coin C is proper. It consists of a device 5.

The ball passage 2 is converted from a vertical passage 2a located at the rear of the machine body 1 and communicating with the ball supply system to the front side via an oblique passage 2b, and is installed vertically along the front surface of the machine body 1. It communicates with the ball outlet 6 through a vertical passage 2c.

Inside the front side of the machine body 1, as shown in FIG. , the lower end extends from the cut hole 11 formed in the ball passage 2c to the passage 2c.
When the ball path 2c is filled with pachinko balls, the ball detection section 12 is pushed back by the pachinko balls, and in that case, the shielding section 10 moves out of the coin slot 9 to open it, and when there are no pachinko balls in the ball passage 2c, the ball detection unit 12 detects the passage 2c by weight balance or spring bias.
The shielding part 10 advances in front of the coin insertion slot 9, so that coins cannot be inserted.

In this case, a display 13 indicating "Rental" and "Cancelled" is provided near the shielding part 10, and when the ball passage 2c is full of pachinko balls, "Rental" is displayed, but when there are no pachinko balls. At that time, "Cancelled" is displayed through a window 14 opened near the coin slot 9 for the convenience of the user.

Incidentally, since the coin sorting machine 4 uses a known one, the explanation of its configuration will be omitted.

Next, the construction of the pachinko ball dispensing device 5 will be explained with reference to the enlarged view shown in FIG. A ball counter plate 16 in the form of a star foil, which partially projects into the ball passage 2c, is rotatably attached to the machine frame 15 by a shaft 17,
The pachinko ball is arranged so that it is fed one tooth at a time while passing one pachinko ball.

In the illustrated embodiment, the concave portion between each tooth of the ball counter plate 16 is formed in a curved concave shape corresponding to the radius of the pachinko ball.
The number of teeth is 10, and it is configured so that 10 pachinko balls pass through it to rotate once.

A gear 20 is attached to a shaft 19 provided parallel to the shaft 17 of the
Two cams 21A and 21B whose phases are shifted from each other and a ball counter stop plate 22 are attached so as to rotate together.

The gears 18 and 20 are interlocked by an intermediate gear 18a, and the gears 18 . The tooth ratio of 20 is set such that the number of teeth of the ball counter plate 16 is rotated by the number of pachinko balls corresponding to one predetermined coin C while the gear 20 rotates once.

The ball counter stop plate 22 has a stepped portion 23 formed on a part of its outer periphery, and a large diameter portion 24 extending over a required range from the stepped portion 23 toward the rear in the rotational direction. It has a habit of rotating clockwise in the figure within the allowable range of movement.

A stop pawl 28 of a stop release lever 27 is disposed on the stepped portion 23 so as to be freely engageable.

This stop release lever 27 is rotatably supported on the machine frame 15 by a shaft 27a, and has a coin abutting portion 29 at one end thereof.
is provided protrudingly movable up and down in the coin passage 30, so that the coin C falling inside the passage 30 is struck by the upper surface thereof.

Also, a weight 31 is provided on the other end side of the stop release lever 27.
is provided so that when the coin C collides with the coin abutting portion 29, the stop claw 28 is easily removed from the stepped portion 23.

The stop release lever 27 needs to be made of a lightweight material such as plastic or light metal so that it can react more sensitively to a collision when the coin C falls due to its own weight.

The coin stopper 32 is pivotally supported by a shaft 33 on the machine frame 15 at a position spaced apart above the coin abutting portion 29 of the stocker release lever 27, and the coin passage 30 side surface of the upper end portion thereof is pivoted. It is formed into an arc-shaped coin fitting part 34 that can be engaged with a part of C, and the lower part is formed in the coin passage 3.
When hanging down, the upper end 34a of the coin fitting part 34 is placed in the same plane as the inner wall surface 30a of the coin passage 30, and the lower end 34b is necessarily placed in the same plane as the inner wall surface 30a of the coin passage 30. 30 to prevent the coin C from falling.

In the part of the coin stopper 32 facing the coin passage 30 side, there is formed a recess 35 in the shape of a U-shape. A pin 37 is fitted therein, and the pin 37 is disposed so as to come out of the recess 35 when the coin stopper 32 moves counterclockwise to allow the coin C to pass.

The coin stop lever lock lever 38 is attached to the shaft 39 on the machine frame 15.
The lock portion 40 is disposed so as to be engageable with the stepped portion 41 of the coin stopper 32 by the bias of a spring 42.

The return lever 43, which ensures the return of the stop release lever 27, is pivotally supported on the machine frame 15 by a shaft 44, and one end of which is supported by a spring 45 so that the protrusion is slightly in front of the cam 21A.
An arm 4 is pressed against the cam surface of the arm 4 and extends to the other end of the arm 4.
6 is disposed such that it can be freely engaged with an arm 47 extending above the stop release lever 27, and the return lever 43 is connected to the cam 2.
1A, the arm 46 comes into contact with the arm 47 of the stop release lever 27, and this release lever 2
7 does not return at a predetermined timing due to clogging with garbage or other reasons, it is forcibly returned.

Further, the opposite end portion 48 can freely come into contact with the back surface of the coin stopper 32, and when pushed up by the cam 21A as described above, the coin stopper 32 is moved to the coin stop position (fourth coin stop position).
The state shown in Figure B) is suppressed.

An auxiliary lever 49 is pivotally supported on the same axis as the return lever 43. One end of this auxiliary lever 49 is pressed against the rearwardly displaced cam 21B under the force of a spring 50, and the other end 51 is It can freely come into contact with the back surface of the lock lever 38,
When pushed up by the cam 21B, the lock lever 38 is removed from the stepped portion 41 of the coin stopper 32.

In FIGS. 1 and 3, 52 is a cabana for reliably feeding the ball counter plate 16 one tooth at a time, and 53 is an outlet for discharging fraudulent coins.

Next, the operation of the above embodiment will be explained.

When pachinko balls are being supplied to the automatic pachinko ball lending machine, the pachinko balls fill the ball passages 2a, 2b and 2c, and reach the ball counter plate 16.

At this time, in the ball dispensing device 5, the stop claw 28 of the stop release lever 27 is engaged with the stepped portion 23 of the ball counter stop plate 22, as shown in the third diagram, so that the gear 20 integral therewith is stopped. , therefore the intermediate gear 18a
Since the gear 18 that meshes with the gear 18 is also stopped, even if the load of the pachinko balls is applied to the teeth of the ball counter plate 16, which is integrated with the gear 18, it does not rotate and remains stationary.

At the same time, the ball detecting part 12 of the swinging rod 7 is pushed by the pachinko balls in the ball passage 2c and is pushed out of the passage 2c, so the shielding part 10 at the opposite end moves out of the coin slot 9 and at the same time A display 13 indicating "Rental" appears in the window hole 14, indicating that it is available for use.

In this situation, when a coin C is inserted into the coin slot 9, it passes through the coin passage 3 and enters the coin sorting machine 4.
Here, it is determined whether the coin is a proper coin or not.

When the coin C is proper, it is fed into the coin passage 30, and when it is an unauthorized coin, it is returned from the outlet 53.

The coin C1 fed into the coin passage 30 is shown in FIG. 4A.
, once it enters the coin fitting part 34 of the coin stopper 32 as shown in FIG. 5A.

Then, due to the weight of the coin C, the lower end 3 of the fitting part 34
4b, the coin stopper 32 rotates counterclockwise around the shaft 33 as shown in FIG. 5B, allowing the coin C1 to pass.

When the coin stopper 32 rotates enough to allow the coin C to pass as described above, the stepped portion 41 locks onto the lock lever 38.
The coins are engaged with the lock portion 4o as shown in FIGS. 4B and 5C, and cannot be returned, thereby preventing two or more coins from passing through at the same time even if a plurality of coins are inserted at the same time.

Therefore, even if several coins C2, C3 are inserted at the same time, the second and subsequent coins C2, C3... It is fastened against the upper end 34a of the.

Further, due to the rotation of the coin stopper 32, its recess 35 is disengaged from the pin 37 at the tip of the arm 36 of the stop release lever 27, and the release lever 27 becomes ready to rotate.

As described above, the coin fitting portion 3 of the coin stopper 32 is
4, the coin C, which has passed through the coin fitting part 34, accelerates and collides with the coin abutting part 29 of the stop release lever 27, which is positioned with a required height from the coin fitting part 34, and collides with the stop release lever 27 due to the impact. The shaft 27a
Rotate counterclockwise around the center (Fig. 4B).

The rotation of the stop lever 27 at this time acts on the weight 31, and due to the inertia of its initial movement, the stop release lever 2
7 will be rotated slowly and greatly.

The coin C, which has been rotated by the stop release lever 27 as described above, falls onto the back side of the machine body 1 and is collected by a conveyor or the like (not shown).

When the stop release lever 27 is rotated counterclockwise, the stop claw 28 touches the ball counter stop plate 2.
It comes off from the stepped portion 23 of No. 2.

Then, the ball counter stop plate 22 momentarily rotates clockwise by the action of the spring 25 to the extent that it contacts the stopper 26, and as shown in FIG. Even if the stop release lever 27 is rotated to its original position by the action of the weight 31, the stop pawl 28 does not engage with the stepped portion 23.

Therefore, the gear 20 including the ball counter stop plate 22 and the cams 21A, 21B, which have been restrained by the stop pawl 28, are now able to rotate.

As the gear 20 is released, the ball counter plate 16 begins to rotate due to the weight of the pachinko balls, and the stepped portion 23 of the ball counter stop plate 22 hits the stop claw 28 again as shown in FIG. 6A. Rotate until.

When the ball counter stop plate 22 rotates once and the step 23 hits the stop claw 28 of the stop release lever 27 and stops, the gear 20.18 also stops, and the ball counter plate 16 also stops, stopping the pachinko ball from being thrown. It stops coming out.

Until this stop, a number of pachinko balls corresponding to the captured coins C1 are ejected from the ejection port 6 into an external saucer or the like.

On the other hand, when the stop release lever 27 is rotated by the collision of the coin C, its arm 47 is located behind the arm 46 of the return lever 43 as shown in FIGS. 4B and 5B.

When the stop release lever 27 rotates clockwise due to the weight of the weight 31 and returns to its original position (the state shown in FIG. 4C), its arm 47 separates from the arm 46 and comes into contact with the cam of the return lever 43. The side of the auxiliary lever 49 is pushed up by the cam 21A as shown in FIG.
Pushed up by B, the tip 4 of the return lever 43
8 is located behind the coin stopper 32, and at the same time, the auxiliary lever 49 pushes the lock lever 38 and locks the lock part 4.
0 from the stepped portion 41 of the coin stopper 32.

As a result, the coin stopper 32 is rotated clockwise due to its own weight as shown in FIG. On the other hand, since the upper end 34a of the coin fitting part 34 of the coin stopper 32 retreats, the next coin C2 falls to fit into the coin fitting part 34, and the coin stopper 32 is rotated (FIG. 5F). state), the coin C2 is brought into contact with the tip end 48 of the return lever 43, and the coin C2 is temporarily held in the coin fitting part 34.

The cam contact part of the return lever 43 is connected to the cam 2 as shown in Fig. 5H.
When the coin falls onto the stepped portion 1a, the tip 48 moves diagonally upward and to the right in the figure, allowing the coin stopper 32 to rotate, resulting in the same effect as in the case of the first coin C described above.

As is clear from the above explanation, the automatic pachinko ball dispensing machine according to the present invention performs the operation of dispensing a fixed amount of pachinko balls based on the insertion of a coin by purely mechanical means without using any electrical means. As a result, the ball rental machine can be installed at the same time as the pachinko machine without any electrical work being done, which significantly shortens the installation period and eliminates the need for electrical parts such as solenoids and magnets. Since it is not used, it can be manufactured at a very low cost, and since there are no electrical failures, it is easy to maintain, which is an excellent effect that cannot be obtained with conventional products.

In addition, the energy for the pachinko ball throwing operation is made by effectively utilizing the impact force caused by the falling acceleration of the coins being thrown in, and by using the weight of the pachinko balls themselves to force the counting and throwing. This is not necessary at all, and in particular, the falling force of the coin is used as the force to release the stop of the counting mechanism, so even a small coin can be operated reliably. Each member can be obtained by molding synthetic resin, etc.
It can be provided at an extremely low cost.
