Description

[Detailed description of the invention] (Field of industrial application) This invention can be used to deal with foreign objects such as coins or cards that have accidentally gotten into the gutter that collects the pachinko balls ejected from the pachinko machine. This invention relates to a foreign matter removal device that can remove foreign matter.

(Prior art) In order to collect the pachinko balls discharged from the pachinko machines installed in parallel in the horizontal direction of each island toward the pachinko ball lifting device, a drainage gutter is installed below and behind the rows of pachinko machines. There is. Nails, screws, etc. used during construction work to open new pachinko parlors or replace new pachinko machines fall into this gutter, and the spread of inter-machine ball rental machines installed between pachinko machines. As a result, when the coins inserted into the inter-machine coin dispensing machine are rolled to the coin collecting device from the back of each inter-machine dispensing machine to be collected all at once, the coins may accidentally fall and fall into the gutter. These foreign objects may get mixed into the flowing pachinko balls and become obstacles, preventing the collection of pachinko balls, or may be sent along with the falling pachinko balls toward the high-speed rotating pachinko ball lifting device. This caused the failure of these devices. For this reason, foreign matter removal mechanisms in the downstream gutter have been devised for some time.
-10612 (hereinafter referred to as Reference 2) and Utility Model 59-64181
(hereinafter referred to as Reference 3).

The foreign object removal mechanism 40 described in Reference 1 will be explained based on FIG. 5. Pachinko balls ejected from each pachinko machine are removed by installing an upper drainboard gutter 42 and a lower drainboard gutter 45 in the middle of a game gutter 41. A large number of drop holes 44 slightly larger than the diameter of a pachinko ball are bored in the bottom plate 43 of the upper drainboard gutter 42. The lower drainboard gutter 45 has a structure in which a large number of square or rod-shaped drainboard materials are arranged in parallel in the longitudinal direction with a gap smaller than the diameter of the pachinko ball.

Next, the foreign matter removal mechanism 50 described in Reference 2 will be explained based on FIG. A ball passage 53 consisting of a wall surface and a bottom surface is formed, and each of these plurality of ball passages 53 is configured so that pachinko balls are aligned and roll in a line. The bottom surface of the ball passage 53 has a parallel groove 54 formed along the wall surface of the partition wall 52, and a central groove 55 provided at a center of the bottom surface different from the parallel groove 54, each having a groove width. The groove is formed to be wider than the thickness of the coin, and the length of the groove is at least longer than the diameter of the coin, and is formed to penetrate the bottom surface of the ball passage 53. In addition, the partition wall 5
2 is formed with an almost mountain-shaped slope toward the downstream side of the downflow gutter 51, and the central partition wall is set higher than the partition walls on both sides so that coins stuck between the tops of the adjacent partition walls will fall down. This is what I did.

Next, the foreign matter removal mechanism 60 described in Reference 3 will be explained based on FIG. 7. A plurality of rods 62 are arranged in parallel in the middle of a downflow gutter 61 with gaps that prevent pachinko balls from falling. Then, the blocking plate 63, which is sloped smoothly upward from the upper surface of the bar 62, is attached to the upstream side end of the downflow gutter 61, with a gap larger than the diameter of a pachinko ball and smaller than the diameter of a coin, to the bar 62.
These conventional techniques are designed to remove relatively small-diameter foreign objects such as nails, screws, or coins that are mixed into the pachinko balls flowing down in the downflow gutter 61. It was designed with the aim of

However, in recent years, a card-type ball lending machine system has appeared as a cashless system that rents out pachinko balls by inserting a card into the machine. Cards have come to be included as foreign substances in the storage.

(Problem that the invention aims to solve) Generally, only 100 yen coins could be used in inter-machine ball lending machines installed between pachinko machines in game parlors, but recently 500 yen coins have been accepted. Along with the issuance of coins, there are inter-machine coin lending machines that can be used with 100 yen and 500 yen coins, as well as inter-machine coin lending machines that can also be used with 1000 yen bills.

However, inter-machine coin lending machines that can accept both 100 yen, 500 yen coins, and 1000 yen banknotes are capable of collecting inserted coins, sorting different types of coins, collecting and transporting 1000 yen banknotes, and also dispensing change. , not only would complex mechanisms such as resupply be required on the island, but
Financial troubles such as discrepancies between the sales at the game parlor and the collected cash often occur, and it is often difficult to manage cash at the game parlor, so we have developed a card-operated ball lending machine system that does not handle cash and is a cashless system. has been developed and provided.
The card-type inter-machine ball lending machine of the card-type ball lending machine system lends out pachinko balls by inserting a card purchased from a card issuing machine into the card slot.

This card-type inter-machine ball rental machine is installed between pachinko machines, and there is a small gap between each machine, and because players insert their cards into the card slot while playing, it is easy to accidentally insert a card with a balance. In some cases, players intentionally insert used cards into the gaps. Cards inserted through the gaps may fall into the gutter, and the cards may interfere with the collection of pachinko balls that are flowing smoothly down the gutter, or they may be sent all at once into the pachinko ball lifting device. This has caused damage to the equipment.

In view of this situation, it is important not only to prevent foreign objects such as coins from accidentally getting mixed into pachinko balls flowing down the drain, but also to remove foreign objects such as coins that accidentally get mixed into the pachinko balls flowing down the drain, even if the drain is in the drain at a game parlor that has introduced a card-type ball lending machine system. It is necessary to quickly and accurately remove cards, etc. from outside the gutter.
When attempting to remove a card using the foreign object removing mechanism configurations of Reference 1, Reference 2, and Reference 3, the following problems arise, respectively.

In Reference 1, the card R mixed with the falling pachinko balls and flowing down the drain gutter 41 is sent into the upper drainboard gutter 42 and stays there, and the card R falls into the drop hole formed in the bottom plate 43 of the upper drainboard. 44, the flow of pachinko balls in the downflow gutter 41 becomes stagnant, making it difficult to smoothly collect the pachinko balls discharged from each pachinko machine thereafter.

In Reference 2, the ball passage 53 consisting of the partition wall 52 and the bottom installed diagonally in the middle of the downflow gutter 51 is configured so that the pachinko balls roll in a line, so it is extremely narrow and the ball passage 53 is extremely narrow. When the cards R and the coins Q, which have been mixed in and flowed down the gutter, stand up and are sent into the ball passage 53 at the same time, they tilt against the walls on both sides and close the ball passage 53, causing the pachinko balls to fall. flow becomes impossible. Further, when a card R mixed in a pachinko ball rides on the diagonally installed partition wall 51 and then falls into the ball path 53, the same problem occurs in that the ball path 53 is blocked.

In Reference 3, the card R mixed with pachinko balls and flowing down the gutter 61 is blocked by the upwardly inclined blocking plate 63, rides on the inclined part, and stays there, so that the lower end of the card R reaches the bar 62. The upper surface is blocked, preventing the pachinko balls from flowing down in the downflow gutter 61, making it difficult to smoothly collect the pachinko balls.

The present invention solves the above-mentioned problems and is capable of quickly and accurately removing foreign objects such as coins, etc. mixed into pachinko balls flowing in the downflow gutter, as well as cards. The purpose is to provide equipment.

(Means for Solving the Problems) The configuration of the present invention, which was created to solve the above problems, is to use a drainage gutter that collects pachinko balls discharged from a plurality of pachinko machines installed in parallel as a pachinko ball. It is sloped toward the lifting device, and a sorting gutter is installed at the lowest position downstream of the flow gutter, and the sorting gutter has a plurality of through holes in the bottom that are larger than the diameter of the pachinko balls. A perforated plate is provided, surrounded by side walls on both sides and a ball stopper plate, a dam plate is provided on one of the side walls and projects diagonally, and a lower end of the ball stopper plate is connected to the perforated plate. A gap is provided in between to allow foreign matter to pass through, and a shelf board for storing foreign matter that has passed through the gap is formed extending from the perforated plate, and a blocking plate is bent at the end, and the ball stopping plate is It is equipped with a notification sensor that detects blockage of the through holes in the perforated plate.

(Function) The foreign matter removal device in the pachinko ball flow down gutter of the present invention configured as described above allows a large amount of pachinko balls discharged from each pachinko machine to roll in the flow down gutter to the lowest position in the downstream part. Pachinko balls are sent into the sorting gutter installed at the site, but a phenomenon occurs in which the pachinko balls push against each other in the sorting gutter, supporting each other and forming a bridge-like stagnation. It does not accumulate in the through hole on the rear side of the dam plate. This is because a large number of pachinko balls sent in hit the side of the obliquely protruding dam plate and are pushed into the other side wall.

Therefore, the following pachinko balls collapse toward the through-hole side near the reinforcing plate due to the downward pressure, and the pachinko balls that were staying are dispersed and all the pachinko balls fall from the through-hole, and the pachinko ball lifting device Go inward.

In addition, foreign objects such as coins or cards mixed in with the pachinko balls are sent by the downward pressure of the pachinko balls, pass through the gap between the lower end of the ball stopper plate and the perforated plate, and are removed to the outside of the shelf gutter. Therefore, the through holes of the perforated plate are not blocked.

Furthermore, even if multiple cards are fed in and block the through-hole of the perforated plate, this can be detected by the notification sensor attached to the ball stopper, making it possible to detect the situation early and remove the cards. It's becoming possible.

(Example) An embodiment of the present invention will be explained with reference to the drawings.

FIG. 2 is an overall front view of the pachinko ball transport device, with a portion of the device vertically cut away. In the figure, on both sides of the central pachinko ball lifting device (hereinafter simply referred to as lifting device), pachinko balls (hereinafter simply referred to as ball P) discharged from each pachinko machine installed horizontally in parallel are allowed to flow down and are collected. A downflow gutter 1 is inclined toward the lifting device. A sorting gutter A, which is the foreign matter removing device 13 of the present invention, is installed at the lowest position downstream of the downstream gutter 1 on both sides toward the lifting device.

The foreign matter removing device 13 separates foreign matter and balls P,
The balls P fall from the through hole 4 and are collected in the collection ball drop gutter 15. The collected spheres P are sent into a horizontal transfer pipe while being mixed with abrasive grains.

A transfer spiral body 17 that is rotationally driven by a transfer motor 18 is inserted into the horizontal transfer pipe 16, and is agitated by the balls P and abrasive grains fed into the horizontal transfer pipe 16. It is lifted by a lifting spiral body 20 within a pipe 19.
Reference numeral 21 denotes a lifting motor that rotates the lifting spiral body 20.

In FIG. 1a, a perforated plate 2 with a plurality of through holes 4 slightly larger than the diameter of a pachinko ball formed at the downstream end of the downflow gutter 1, left and right side walls 3, 3a, and a ball stopper plate 5 are shown.
It is formed into a U-shape and is called a sorting gutter A.

Reference numeral 5 denotes a ball stopper plate of the sorting gutter A, and a gap 6 is provided between the lower end and the other hole plate 2 to allow foreign matter to pass through.The gap 6 is narrower than the diameter of the balls, but coins that have piled up can be removed. is formed so that it can pass through. Also,
Two notification sensors 1 are mounted on the ball stopper plate 5 at an interval.
1, 11a are attached. Note that the notification sensor will be explained later.

7 is a dam plate projecting diagonally from one of the side walls 3a, and 8 is a reinforcing plate to prevent the dam plate 7 from being distorted. This is to prevent distortion even if repeated.

Reference numeral 9 denotes a shelf board for storing foreign matter that has passed through the gap 6 outside the gutter, and the storage shelf B is formed by extending from the perforated plate 2, and a blocking plate 10 is bent at the end to prevent foreign matter from falling. It is prevented.

Reference numerals 11 and 11a indicate notification sensors, and in order to detect coins Q and cards R, for example, a light reflection type sensor is attached to the ball stopper plate 5.

Next, the effect will be explained.

A large amount of balls P ejected from each pachinko machine on the island gather together and flow through the downflow gutter 1 toward the downstream lifting device.
The comrades push each other in the U-shaped sorting trough A, supporting each other and forming a bridge shape, which is likely to stagnate. Does not stagnate. This is because, among the balls P sent in, the balls P on the side wall 3a impact along the side surface of the dam plate 7 that projects obliquely from the side wall 3a, and are pushed into the other side wall 3 side. As a result, the balls P pushed into the side wall 3 side collapse toward the through hole 4 side near the reinforcing plate 8 due to the downward pressure of the following balls P, and eventually the balls P are dispersed and push away from the through hole 4. All the balls P fall downward.

Further, the foreign matter that has mixed with the balls P is pushed by the downward pressure of the balls P that are coming together, gradually passes through the gap 6, and is stored on the shelf board 9.

In the diagram shown in Figure 1b, multiple coins Q are placed in the gap 6.
This figure shows the state when the liquid passes through and is stored on the shelf board 9.

The diagram shown in FIG. 1c shows a state in which a plurality of cards R have passed through the gap 6 and are stored on the shelf board 9.

In addition, in the above, foreign objects (coin Q, card R)
If a situation occurs in which foreign matter accumulates on the shelf board 9 and cannot fit on the shelf board 9, and foreign matter accumulates near the gap 6 of the ball stopper plate 5 and blocks the through hole 4, the notification sensor 1
1, 11a immediately detects the foreign matter and sends a sensor output to the outside to notify the store staff, allowing early countermeasures (removal of foreign matter).

Next, FIG. 3 a, b and FIG. 4 a, b will be explained.

A large amount of balls P discharged from each pachinko machine flow down in a mass and are sent into the sorting gutter A, where they stay together in the sorting gutter A, and the individual balls P push against each other and support each other, forming a bridge shape. As a measure to prevent the ball P from falling smoothly through the through hole 4, the dam plate 7 is protruded diagonally toward the side wall 3a in the sorting gutter A, thereby preventing the ball P from falling smoothly through the through hole 1.
It plays the role of reducing the momentum of the ball P flowing down. That is, the balls P flowing down in a straight line in the downflow gutter 1 are struck along the side of the dam plate 7 and are once guided to the other side wall 3 side, so that the reinforcing plate 8
Since it does not stay in the nearby through hole 4, it does not form a bridge shape.

In other words, among the foreign objects such as coins Q and cards R mixed in with the balls P flowing through the downflow gutter 1 at the game parlor, the balls P fall through the through holes 4 of the perforated plate 2 of the sorting gutter A, and the foreign objects Since the balls P pass through the gap 6 and are removed out of the gutter of the shelf board 9 by the downward pressure, the balls P can be recovered without the through holes 4 being blocked by foreign objects. Further, since foreign objects can be reliably captured, the equipment of the lifting device will not be damaged.

(Effect of the invention) As is clear from the above explanation, the foreign matter removal mechanism in the pachinko ball flow gutter of the present invention is a flow down gutter that collects pachinko balls ejected from multiple pachinko machines installed in parallel. The gutter is sloped toward the pachinko ball lifting device, and a sorting gutter is installed at the lowest position downstream of the gutter, and the sorting gutter has a through hole in the bottom that is larger than the diameter of the pachinko balls. A perforated plate having a plurality of perforations is provided, and is formed so as to be surrounded by side walls and a ball stopper plate on both sides, and a dam plate that protrudes diagonally from one of the side walls is provided, and further,
A gap is provided between the lower end of the ball stopper plate and the perforated plate to allow foreign matter to pass through, a shelf board is formed extending from the perforated plate to store the foreign matter that has passed through the gap, and a stopper plate is folded at the end. By attaching a notification sensor to the ball stopping plate to detect the blockage of the through hole of the perforated plate, the following effects are produced.

Foreign objects can be removed from drains at both game parlors that have inter-table ball lending machines that rent out balls with coins, and those that have inter-machine ball lending machines that rent out balls with cards. With this system, foreign objects such as coins or cards that accidentally get mixed into the pachinko balls flowing through the downflow gutter can be separated into pachinko balls and foreign objects through the perforated plate of the sorting gutter. Therefore, the pachinko balls can be collected smoothly without any accumulation, and damage to the pachinko ball transport device and the like can also be prevented.

In addition, since the foreign matter mixed with the pachinko balls is pushed out of the gutter of the shelf board by the downward pressure, no foreign matter remains in the sorting gutter, and the through holes of the perforated plate are not blocked by foreign matter.

In addition, foreign matter is pushed out onto the shelf board through the gap at the bottom of the ball stopper, but even if too much accumulates on the shelf board and stagnates in the gap, the notification sensor will immediately detect this situation and notify the store staff. It can be dealt with at an early stage.

In addition, since a diagonally protruding dam plate is provided on the side wall of the sorting gutter, even if pachinko balls flow down in bunches, the pachinko balls will not remain in the form of a bridge in the sorting gutter and will be sorted and dropped. It has the effect that it can be processed accurately.
