Description

[Detailed description of the invention] (Field of industrial application) The present invention is a pachinko ball lifting device that lifts dirty pachinko balls while polishing them with abrasive grains such as synthetic resin, especially for pachinko machines. This invention relates to a ball flow rate adjustment mechanism for re-polishing and transporting pachinko balls that have been discharged from a machine.

(Prior art) Conventionally, a V-shaped ball guide was installed on a pachinko ball collection gutter (hereinafter sometimes abbreviated as collection gutter) connected to the front part of a ball inlet bored in a circulation pipe. The plates were fixed, and the pachinko balls rolling through the left and right collection channels were always guided to the ball inlet at approximately the same rate on the left and right sides, regardless of the amount of pachinko balls.

Alternatively, the ball guide plate was not provided, and the pachinko balls were allowed to roll and flowed into the ball inlet.

(Problem that the invention aims to solve) Therefore, if the amount of pachinko balls discharged from the pachinko machine is different on both sides of the pachinko ball lifting device located in the center of the island, a large number of balls will be processed (lifted through the ball inlet). Pachinko balls on the side that should be introduced into the feeding device (introduced into the feeding device) remain on the collection gutter, and on the side where it is better to handle less, the pachinko balls disappear from the collection gutter, and in the end, pachinko balls are distributed evenly on the left and right on the collection gutter. There is a problem in that the processing time is longer when the total amount of pachinko balls is the same than when the total amount of pachinko balls is the same. This becomes especially clear when the pachinko balls are loaded into the supply gutter for the next day after the store closes, and it takes a very long time when the number of pachinko balls on the left and right sides of the collection gutter is uneven.

The purpose of this invention is that even if there is a difference in the amount of pachinko balls on the collection gutter on both sides of the pachinko ball lifting device located at the center of the island, the processing time for introducing the pachinko balls into the lifting device is equal. To provide a ball flow rate adjustment mechanism that can adjust the amount of pachinko balls falling from a collection gutter to a ball inflow port so that the amount of balls falling from a collection gutter to a ball inflow port is different from that of the left and right sides.

(Means for Solving the Problem) In order to achieve the above object, the present invention provides a pachinko ball that polishes the pachinko balls discharged from a pachinko machine while stirring them with abrasive grains, and then transports the pachinko balls. The lifting device is a pachinko ball collecting gutter which is sloped so that the ball inflow port is at a low position with respect to both ends. A ball guiding plate 1a is disposed diagonally from the side plate of the collection gutter toward the ball inflow port so that the pachinko balls rolling on the other collection gutter are introduced into the ball inflow port in the same manner as described above. A guide plate 1b is provided, and the ball guide plate 1
a and 1b form a V-shape, and the tip of the V-shape is formed close to the ball inlet, and the ball guide plates 1a and 1b are formed into elongated adjustment holes drilled in the pachinko ball collection gutter. The ball guide plates 1a and 1b are formed so as to be slidable along the adjustment holes, and the ball guide plates 1a and 1b can be fixed at any position of the adjustment hole by a fixing member.

(Function) The pachinko ball lifting device according to the present invention is installed in the center of an island made up of pachinko machines, and the pachinko balls discharged from each pachinko machine are arranged at an angle at the bottom. The balls roll through the pachinko ball collection gutter and flow into the ball inlet provided in the side of the circulation pipe of the pachinko ball lifting device. At this time, if a ball guide plate is not installed on the pachinko ball collection gutter connected to the ball inlet to introduce the pachinko balls rolling from both left and right sides into the lifting device via the ball inlet, Pachinko balls collide from both sides in front of the ball inlet (exactly at the center and bottom of the ball collection gutter) and are pushed against each other, preventing them from flowing smoothly into the ball inlet. Ball guide plates 1a and 1b are provided toward the center, and 1a and 1b form a V-shape, with their tips close to the ball inlet, so that the balls can roll in the pachinko ball collection gutter from both the left and right sides. Incoming pachinko balls are smoothly guided to the ball inlet and flow into the ball inlet. In addition, the ball guide plate slides along the elongated adjustment hole drilled in the outer side plate of the collection gutter and can be fixed at any position, allowing pachinko players on the left and right of the ball inlet When the amount of pachinko balls on the ball collection gutter is different, the ball guide plate on the side with a larger amount of balls can be slid to the side with a smaller amount of balls, and the opening of the ball inflow port on that side can be made larger. Conversely, on the side with a smaller amount of balls, the opening of the ball inlet can be made smaller.

(Example) Examples of the present invention will be described in detail below based on the drawings.

FIG. 1 is a perspective view of the present invention, with the ball guide plate 1 at the frontmost position. Further, FIG. 2 is a perspective view of the ball guide plate 1 when it is at the innermost position.

The ball guide plate 1 is located at the lowest point of the pachinko ball collection gutter 6 provided with an inclination, and is attached to fixing members 28a and 28b that fit into elongated adjustment holes 27a and 27b provided in the side plate 26. Side plate 26
is attached to. Also, the ball guide plate 1 is 1a
Screw 4a is formed in a V-shape by 1b and 1b, and transfers the pachinko balls rolling through the pachinko ball collection gutter 6 on both sides to the lifting pipe 3 together with the abrasive grains.
The ball is guided to a ball inlet 31 formed in the circulation pipe 4 through which it is directly refluxed. In the present invention, by forming the ball guide plate 1 in a V-shape, pachinko balls rolling from both sides are smoothly guided to the ball inlet 31. If this ball guide plate 1 were not present, the pachinko balls rolling from both sides would collide with each other near the ball inlet 31 and would not flow into the ball inlet 31 properly, and the ball guide plate would not be V-shaped. Similarly, when the pachinko balls are a flat plate provided at right angles to the side plate 26, the ball inlet 3
1 does not flow well.

The ball guide plate 1 includes fixing members 28a and 28b.
This allows the positions of the adjustment holes 27a, 27b to be changed in the longitudinal direction. As a result, collection gutter 6
When the flow rates of the balls on the left and right sides are different, the ball guide plate 1 is slid and attached to the side with a lower flow rate so that the side with a higher flow rate of the ball is wide open and the side with a lower flow rate is narrower. Pachinko balls flowing into the inlet 31 roll smoothly.

The pachinko ball collection gutter 6 is placed above the pachinko ball collection gutter 6 to prevent coins that have fallen from the coin conveyor belt, etc. that transports and collects coins inserted into inter-machine ball rental machines installed on the island to a predetermined location, from mixing with pachinko balls. Coin storage section 3
2 is formed, and the pachinko balls pass through the hole 33 and fall onto the collection gutter 6, but since the coins C are larger than the hole 33, they are stored in the coin storage section 32.

This prevents the pachinko balls and the screws 3b and 4a from being damaged if the coins C get mixed into the lifting device 2.

As shown in FIG. 3A, the pachinko ball lifting device 2 is installed in the center of an island made up of pachinko machines, and has a lifting pipe 3 in the center. A lifting screw 3b is installed inside the lifting pipe 3 and is rotated by a lifting motor 3a. Balls discharged from the pachinko machine are collected through the ball inlet 31 by rolling through the collection gutter 6. Pachinko balls are transferred by a transfer screw 4a installed inside the circulation pipe 4.
The abrasive particles are directly returned to the lower end of the lift pipe 3 together with the abrasive particles. The pachinko balls are stirred and mixed with abrasive grains by a lifting screw 3b in the lifting pipe 3, dirt is removed, and the balls are discharged to the sorting device 7 located at the top.

A lid 9 is attached to the top surface of the sorting device 7, which prevents dust from entering from the outside (particularly dust adhering to the lift motor 3a) and increases the ability of the dust collector 8 to collect abrasive dust by sealing the lid 9. There is.

Moreover, the inside of the sorting device 7 is divided into two parts as shown in FIG. 3B.
Separation gutter 1 A separation gutter 10 in the form of a cage formed in stages is connected to the discharge port 5 at the upper part of the lifting pipe 3, and separates the pachinko balls lifted while being polished and the abrasive grains.
A bucket 11 for collecting the abrasive particles that have passed through the separation gutter 10 and fallen is disposed at the bottom of the separation gutter 10.
An abrasive grain recovery hose 12 is connected to the bucket 11. Here, in the past, the abrasive grain recovery hose 12 protruded largely into the bucket 11, so the abrasive grains remained in the gap 13 (as shown by the dotted line in Figure 3B), and the space inside the bucket 11 became smaller due to the protrusion. Therefore, when the abrasive particle cleaning device 20 is operated, the abrasive particles in the bucket 11 are prevented from being at the same height as the separation gutter 10. However, in this embodiment, the bucket 11 is formed completely large inside the sorting device 7, and the abrasive grain collection hose 12 is also connected to the lowermost end of the bucket 11 and provided without protruding into the bucket 11. The shortcomings have been improved.

The pachinko balls separated by the separation gutter 10 fall onto the supply gutter 14, and are supplied to the pachinko machines on the left and right at the same rate.

Further, the polishing dust that has fallen into the bucket 11 is sucked by a dust collection hose 15 connected to the dust collector 8 and stored in a dust collection tank 16.

The abrasive grains that have fallen into the bucket 11 fall through the abrasive grain collection hose 12 and are normally passed through the circulation hose 17.
The pachinko balls are then supplied again to the lower part of the lifting pipe 3, mixed with the recovered pachinko balls, and sent into the lifting pipe 3.

When the abrasive grains become dirty due to repeated use, the abrasive grains are sent into the abrasive grain cleaning circulation hose 19 by the switching lever at the branch point 18, the abrasive grains are cleaned by the abrasive grain cleaning device 20, and then pumped out again. It is returned to the bottom of pipe 3. In addition, the abrasive grain cleaning device 20
As a result, the dirt from the removed abrasive grains is stored in the abrasive grain dust storage box 21 and disposed of outside as appropriate.

Reference numeral 22 denotes an abrasive grain input section, and when the abrasive grains are introduced, the amount of abrasive grains is confirmed through circular confirmation windows 23a and 23b.

Conventionally, a single confirmation window contained a score line, and it was difficult to confirm the amount of abrasive grains using the score line.Furthermore, if the confirmation window became dirty with dirty abrasive grains, etc., the score lines became increasingly visible. This made it even more difficult to confirm the abrasive grains, and the above-mentioned inconvenience was resolved with the implementation of the present invention.

Further, in this embodiment, abrasive grain collection ports were provided at two locations, and the collection port 24a was formed on the side surface of the lifting pipe 3. This is because conventionally, the lifting pipe 3 is located in the center of the island, so the stud 25 and the lifting pipe 3 exactly overlap, and if the abrasive grain collection port is provided in the front of the lifting pipe 3, the work of collecting the abrasive grains is facilitated. This is an improvement on the points that were difficult to implement.

Further, another collection port 24b is formed at the lower part of the lift pipe 3, and is used to collect abrasive grains located at the corner of the lift pipe 3 and the circulation pipe.

In addition, FIGS. 4 and 5 show the lift screw 3b fixed to the output shaft of the lift motor 3a when it is forced to be replaced due to a foreign object, load, etc. 3b is removed or installed. Conventionally, the 5th
As shown in the figure, the lifting screw 3 is
In halls where the length from the board 40 to the ceiling is short (low), the replacement is very laborious, and the length usually requires 400 mm.

In this embodiment, as shown in FIG. 4, the side surface is opened so that the lifting screw 3b can be removed from the side.
The length from zero to the ceiling required 400mm, but the length can be shortened by about 100mm.
Therefore, the pachinko ball lifting device of the present invention can be placed even in halls with low ceiling heights.

Further, 41 is a scattering prevention plate that prevents pachinko balls and abrasive grains discharged from the discharge port 5 from scattering inside the sorting device 7.

(Effect of the invention) As is clear from the above explanation, according to the present invention, a ball guide plate is provided on the pachinko ball collection gutter connected to the ball inflow port, so that the pachinko ball collection gutter can be accessed from both the left and right sides. The pachinko balls rolling inside do not collide and repel each other in the center, but instead roll along the ball guide plate and smoothly flow into the ball inlet.

In addition, the ball guide plate can be fixed at any position by sliding along the elongated adjustment hole drilled in the outer side plate of the pachinko ball collection gutter, so the ball guide plate can be fixed at any position. Its position can be adjusted depending on the amount. In other words, on the side with a large amount of balls, slide the ball guide plate to the side with a small amount of balls to enlarge the opening of the ball inlet on that side, and on the side with a small amount of balls, slide the ball guide plate to the side with a small amount of balls. Since the opening of the ball inflow port on that side can be reduced by moving the ball, there is no longer a situation where there are no pachinko balls on one side of the pachinko ball collection gutter and there are only pachinko balls on the other side. This has the effect of shortening the processing time for transporting and transporting pachinko balls.

This is especially effective after the pachinko parlor closes, when all the pachinko balls are raised to the top and refilled to the pachinko machine for the next day. By adjusting the guide plate, all pachinko balls can be transported in the same amount of time as when the amount of pachinko balls is equal.
