Description

[Detailed Description of the Invention] The present invention relates to a thin ball lending machine that is arranged between so-called island machines in which a large number of pachinko machines are arranged.

In general, pachinko ball lending machines include large ball lending machines that are installed in pachinko halls and use electrical means, and thin ball lending machines that are placed between machines and do not use electrical means.

Thin ball lending machines have the advantage of being low cost because they do not use electrical means, but the ball lending mechanism is activated by the weight of the coins, and two or more coins are inserted in succession. In this case, the coins must be divided into individual coins and supplied to the ball lending mechanism to ensure that pachinko balls equal to the number of coins inserted are lent out. Moreover, this must be done only by mechanical means, without using electrical means.

The purpose of this invention is to separate the coins one by one and supply them to the ball lending mechanism when two or more coins are inserted in succession to ensure that pachinko balls equal to the number of inserted coins are lent out. It is to make it.

In order to achieve this purpose, the coin cutting mechanism of the present invention has a stepped gear that rotates in conjunction with a star wheel that engages with and rotates pachinko balls flowing down a ball path, and a stepped gear that engages and disengages from the stepped portion of the stepped gear. In the ball lending machine, the ball lending machine has a locking pawl that inserts a coin into the coin passageway, and a ball lending mechanism that releases the engagement between the step part and the locking pawl when the coin is inserted into the coin passageway. It has a long arm that swings when a coin comes into contact with the hook, and a hook that enters the coin passage. A coin cutting arm is provided which is formed with a protrusion and is formed with a short arm that enters into the coin and locks the next coin, and the stepped gear is provided with a protrusion that rotates together with the stepped gear so that the protrusion and the coin are separated. Between the protrusions of the cutting arm, there is a stepped part that engages with the protrusion when the coin cutting arm swings, and a contact part that can come into contact with the protrusion of the stepped gear. a first lever that contacts and swings with the protrusion to release the engagement between the stepped portion and the protrusion of the coin cutter arm; a contact portion that can make contact with the protrusion of the stepped gear; and a protrusion of the coin cutter arm; It has a hook part that can be engaged and detached from the coin cutter arm, and when the contact part and the protrusion of the stepped gear come into contact, the engagement between the hook part and the protrusion of the coin cutter arm is released, and when the contact part does not make contact, the hook part is attached to the coin cutter arm. a second lever that engages with the protrusion of the coin cutter arm; The abutting portion of the second lever is placed in a position where it comes into contact with the protrusion of the stepped gear earlier than the abutting portion of the second lever.

Since the proposed coin cutting mechanism has the above configuration,
Coins that are continuously inserted into the coin passage can be cut one by one by regulating the swinging of the coin cutting arm that swings due to the coins using the first and second levers. 1. Since the first lever is actuated by the protrusion of the stepped gear, it has the advantage of not requiring any electrical means.

The illustrated embodiment will be described below.

FIG. 1 is a front view showing an embodiment of a ball lending machine equipped with the proposed coin cutting mechanism, where A shows the ball lending mechanism and B shows the coin cutting mechanism. In addition, 1 is the substrate,
2 is a ball passage, 3 is a coin passage, 4 is a coin sorter, 5 is a ball storage tank, and 6 is a ball takeout tube.
The ball passage 2 is designed to receive pachinko balls from a ball supply passage located on the upper part of the island (not shown), and the coin sorting machine 4 sorts coins inserted into the coin passage 3 from the coin slot 9. Appropriate coins are directly supplied to the coin passage 3', and invalid coins are fed through the discharge passage 7 to the ring-shaped coin receiver 8.
It is now being discharged.

First, the ball lending mechanism A will be explained.

As shown in FIGS. 2 and 3, the ball lending mechanism A includes a star wheel 10, a stepped gear 20, and a locking lever 3.
0, a coin receiving lever 40, and a connecting rod 90.

The star foil 10 is rotatably supported by the base plate 1, and rotates by engaging with pachinko balls (not shown) facing the ball path 2 and flowing down the ball path 2.

The stepped gear 20 includes a gear body 21 and a cam plate 23 having a notch step 25 integrally formed with the gear body 21 through a body 22, and the gear body 21 is a gear fixed coaxially with the star wheel 10. It rotates by meshing with 11.

The locking lever 30 is approximately L-shaped, and has a shaft 31.
is swingably supported on the substrate 1 by. A pawl 32 is formed at one end of the locking lever 30, and when this pawl 32 engages with a step 24 protruding from the body 22 of the stepped gear 20, the rotation of the stepped gear 20 is normally prevented. is regulated, and therefore the rotation of the star wheel 10 is also regulated, so the ball passage 2
The pachinko balls inside will not flow down. Further, a protrusion 33 is formed at the other end of the locking lever 30, and its tip 33a comes into contact with the peripheral edge of the cam plate 23 of the stepped gear 20 when the locking lever 30 swings. (See Figure 4). This protrusion 33 is
It also serves as a weight and constantly biases the lever 30 counterclockwise.

The coin receiving lever 40 is swingably supported by a shaft 41 protruding from the surface of the coin passage 3', and the right side of this shaft 41 is made thin in order to reduce its weight as much as possible. The other side is made wider so that it is heavier. Therefore, the coin receiving lever 40 is always biased counterclockwise. A coin receiving part 42 is provided at the tip of the coin receiving lever 40.
As shown in Figure b, this coin receiving portion 42 is provided to protrude into the coin passage 3'. Corresponding to the coin receiving portion 42 entering the coin passage 3', a long hole 3b' is formed in the wall plate 3a' forming the coin passage 3', and the coin receiving lever 40 is inserted in this range. can oscillate. However, the pin 43 protruding from the left side of the shaft 41 and the pin 34 protruding from the locking lever 30 are connected to the connecting rod 9.
0, the coin receiving lever 40 and the locking lever 30 are interlocked, and the swinging range of the locking lever 30 is restricted by the contact of the protrusion 33 with the cam plate 23. Therefore, the coin receiving lever 40 Also, the movement of the ground is being regulated.

In the coin lending mechanism A as described above, a proper coin is inserted into the coin passage 3, passes through the coin sorter 4, falls down the coin passage 3', and when the coin receiving part 42 of the coin receiving lever is pushed down, the coin receiving lever 40 The locking lever 30 is rotated in the clockwise direction.
also swings clockwise, the engagement between the stepped portion 24 of the stepped gear 20 and the pawl 32 is released, the star wheel 10 rotates under the weight of the pachinko balls, and the pachinko balls flow down the ball path 2 and are rented out. It's starting to become easier.

The proposed coin cutting mechanism separates the coins that are continuously inserted into the ball lending mechanism as described above and supplies them to the ball lending mechanism one by one, thereby ensuring that pachinko balls equal to the number of coins that have been inserted are lent out. The coin cutting arm 50 provided in the coin passageway engages and disengages the pin 26 protruding from the stepped gear 20, and furthermore, the pin 51 protruding from the coin cutting arm 50.
a first member that engages and disengages from the coin cutting arm 50 to regulate the coin cutting arm 50;
It consists of second levers 60 and 70.

The coin cutting arm 50 is connected to the wall plate 3 of the coin passage.
It is swingably supported by a shaft 52 protruding from the surface of a', and has two long and short arms 53 and 54. The lower ends of each arm 53, 54 are formed with hook portions 55, 56 that can penetrate into the coin passage, and the short arm 5
4 has the pin 51 protruding from it. The coin cutting arm 50 is biased by its own weight in the direction in which the hook 55 of the long arm enters the passage, but the inserted coin comes into contact with the hook 55 of the long arm 53 and is pushed out of the passage. When the long arm 53 swings by pushing it away, the short arm 54 swings accordingly, and its hook 5
6 enters the passage and locks the next coin (see Figure 4). In this case as well, the coin cutting arm 50 is biased clockwise in the figure and tries to return to its original position, but as will be described later, the pin 51 engages with the second step portion 53 of the first lever. Return to the original position is regulated.

The first and second levers 60 and 70 have a common shaft 80
It is supported in a swingable manner.

The upper part of the first lever 60 is a contact part that can come into contact with the pin 26 of the stepped gear, and the upper edge 61, which is bent and extended to the left in the figure, is as described below.
It is adapted to come into contact with the protrusion 26. At the bottom of the first lever, there are a first step 62 and a second step 63.
is formed so that when the coin cutting arm 50 swings, its pin 51 and second step portion 63 engage with each other. That is, the first lever 60
is energized in the downward direction by its own weight,
Before coin insertion, one edge 64 of the first step 62
Although the rotation in the clockwise direction is restricted by contacting the pin 51 of the coin cutting arm 50, this contact is released by the rotation of the coin cutting arm 50, and the first lever rotates. This allows the second step portion 63 to engage with the pin 51.

The second lever 70 has a horizontal portion 7 extending to the left in the figure.
1 is biased counterclockwise by the action of a weight 72 provided at the tip of the head 73 which is bent upward.
is the contact part, and this is the pin 2 of the stepped gear.
6, its rotation is restricted. Further, a hook portion 74 is formed at the lower part of the second lever to engage with and disengage from the pin 51 of the coin cutting arm.
4 and the pin 51 of the coin cutting arm are engaged, and the engagement between the hook portion 74 and the pin 51 is released when they come into contact.

And each contact part 61, 73 of the first and second levers
After the hook portion 74 of the second lever and the protrusion 51 of the coin cutter arm are engaged, the abutting portion 61 of the first lever engages the protrusion 26 of the stepped gear earlier than the abutting portion 73 of the second lever. It is placed in a position where it comes into contact with the

Therefore, the pin 51 of the coin cutting arm and the first
The engagement with the second step portion 63 of the lever and the engagement between the pin 51 and the hook portion 74 of the second lever are as follows: First, the engagement with the second step portion 63 of the first lever is released, and then the second step portion 63 of the first lever is disengaged. The lever is disengaged from the hook portion 74.

Hereinafter, the operation of the coin cutting mechanism B will be explained step by step in relation to the coin lending mechanism A.

(i) Before a coin is inserted, the stepped portion 24 of the stepped gear 20 and the pawl 32 of the locking lever 30 are engaged, as shown in FIG.

The coin cutting mechanism B has its coin cutting arm 50.
is in a hanging state, so the hook part 55 of the long arm
The hook portion 56 of the short arm, which is intruding into the passage, is outside the passage. Further, the rotation of the first lever 60 is restricted by the contact of one edge 64 of the first step with the pin 51 of the coin cutting arm, and the second lever 70 is
Rotation is restricted by the head 73 coming into contact with the pin 26 of the stepped gear. Therefore, the pin 51 of the coin cutting arm does not engage with either the second step 63 of the first lever or the hook 74 of the second lever. First of all, the head 73 of the second lever
It is not necessary for the pin 26 to come into contact with the pin 51. For example, as shown in the figure, the hook corner of the second lever is brought into contact with the pin 51.
It may be brought into contact with.

(ii) When a coin is inserted, the coin falls from the coin passage 3 through the coin sorter 4 through the coin passage 3', and then passes through the long arm 5 of the coin cutting arm 50.
The coin collides with the hook of No. 3 and is pushed out of the passage and falls further, pushing down the coin receiving portion 42 of the coin receiving lever 40 (FIG. 4). As a result, the coin receiving lever 40 swings clockwise, the locking lever 30 also swings accordingly, and the engagement between the step part 24 of the stepped gear 20 and the claw 32 is released, and the stepped gear 20 and the pawl 32 are disengaged from each other. Star foil 10 starts rotating. At this time, the protrusion 33 of the locking lever 30
By contacting the peripheral edge of the cam plate 23, the swinging of the coin receiving lever 40 is restricted and stops midway, so that the inserted coin _C1 contacts the lower end 3d of one side wall of the coin passage 3' and the coin C1. It will be moored at the receiving part 42. Also, coin
The coin cutting arm 50, which is swung by C ₁ pushing away the hook portion 55, pushes the pin 5 due to the swiveling.
1 comes off from the first step portion 62 of the first lever 60,
In response to this, the first lever 60 rotates clockwise by the step difference between the first step 62 and the second step 63, and the lever 51 engages with the second step 63, so that it returns to its original position. Returns will be regulated.
In this state, the tip of the hook portion 56 of the short arm 54 protrudes into the coin passage and locks the next successively inserted coin _C2 .

Note that since one edge 64 forming the first step portion 62 of the first lever has an arc shape centered on the shaft 52 of the coin cutter arm, the pin 51 cannot fall into the second step portion 63. It's done smoothly.

(iii) As the stepped gear 20 rotates, the pin 26 of the stepped gear temporarily pushes the head 73 of the second lever 70 to the right in the figure, so that the second lever 70 temporarily However, as shown in FIG. 5, when the pin 26 comes out of contact with the head 73, the second lever 70 swings counterclockwise due to the action of the weight 72. This causes the hook portion 74 of the second lever 70 to
contacts the pin 51 of the coin cutting arm.

(iv) As shown in FIG.
1 and pushes it down, the first lever 60 swings counterclockwise, thereby causing the second lever 60 to swing counterclockwise.
Since the engagement of the coin cutting arm with the pin 51 by the stepped portion 63 is released, the coin cutting arm 50 swings clockwise and attempts to return to its original position, but this time the pin 51 is moved from the second lever 70. Since it engages with the hook portion 74, return to the original position is still restricted. Therefore, the hook portion 56 of the short arm is also in a state of protruding into the coin passage, and the coin _C2 also remains locked.

In this way, the pin 51 by the first lever 60
The reason why the pin 51 is still restricted by the second lever 70 even after the restriction is lifted will be described later.

(v) The stepped gear 20 further rotates, and as shown in FIG.
When the coin falls into the notch step 25, the coin receiving lever 40 also rotates by that amount, thereby disengaging the lower end 3d of one side wall of the coin passage from the coin _C1 , which had been moored until then. At this point, the coin _C1 becomes free and is ejected out of the machine via the ramp 3C.

Since the coin C ₁ is no longer pushed down against the coin receiving part 42, the coin receiving lever 4
0 and the locking lever 30 will return to their original positions (Fig. 8), but at this time, the cam plate 27 acts to push down the projection 33 of the locking lever, so that the return operation can be made more reliably. Ru.

(vi) The stepped gear 20 further rotates, and the pin 26 again touches the head 73 of the second lever 70, as shown in FIG.
By making contact with the second lever 70 and swinging the second lever 70 clockwise, the engagement of the hook portion 74 with the pin 51 of the coin cutting arm 50 is released. At this stage, restrictions on the coin cutting arm 50 are lifted,
Therefore, since the coin cutting arm 50 returns to its original position, the hook portion 56 of the short arm 54 also retreats from the coin passage, and the coin that was previously locked is removed.
C ₂ becomes free and falls, and the same action is repeated.

In the action (iv) explained earlier, the first lever 60
Even after the restrictions on pin 51 were lifted, the second
The reason why the pin 51 is defined by the lever 70 is as follows.

That is, when the first lever 60 is released from the pin 51, the coin cutting arm 50 rotates to return to its original position, and the hook portion 56 of the short arm rotates.
Since the coin C ₂ also retreats from the passage, the lock on the coin C 2 is released and the coin C ₂ falls. At this time coin
Similar to the previously explained coin C ₁ , C ₂ pushes the hook portion 55 of the long arm of the coin cutting arm out of the passage, and as a result, the hook portion 56 of the short arm enters the passage again, and the coin C ₂ is removed. It comes into contact with the next coin C ₃ (not shown). Therefore, at this time, if the contact portion 61 of the first lever 60 and the pin 26 of the stepped gear have already come out of contact and the first lever 60 is in a state where it can be rotated clockwise, the above-mentioned effect is achieved. As explained in (ii), the pin 51 of the coin cutting arm is connected to the first lever 60.
By engaging with the second step portion 63 of the coin cutting arm 50, the return to its original position is restricted, and the hook portion 56 of the short arm is prevented from returning to its original position.
The second lever 70 is not necessary at all since the coin C ₃ can be locked by .

However, in reality, the pin 26 of the stepped gear is in the first position.
Coins C 2 and C ₃ immediately fall when they come into contact with the abutment portion 61 of the lever and the first lever swings to disengage the second step portion ₆₃ from the pin 51.
Since a certain period of time passes before the pin 26 of the stepped gear and the contact part 61 of the first lever are released from contact, the second step part 63 of the first lever is in contact with the pin 51 of the coin cutting arm during that time. Therefore, not only the coin C ₂ but also the next coin C ₃ are released before the pin 26 of the stepped gear and the contact portion 61 are released from the contact state. This does not fulfill the role of a coin cutting mechanism.

Therefore, a second lever 70 is provided, and even after the engagement between the stepped portion 63 of the first lever and the pin 51 is released, the first
The contact part 61 of the lever and the pin 26 of the stepped gear are released from contact, and the step part 63 of the first lever is brought into contact with the pin 51 again.
The hook part 74 of the second lever restricts the pin 51 until the coin can be engaged with the coin.
I decided to release them one by one.
