Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to automatically removing dust from the belt of a pachinko ball conveyor that constitutes a pachinko ball automatic circulation system adopted in a pachinko game hall. This article relates to a belt dust remover for a pachinko ball transfer machine that can be used to transport pachinko balls.

[Conventional technology] Conventionally, pachinko game halls have adopted an automatic pachinko ball circulation system that uses a power source to automatically transport a large number of pachinko balls to form a supply route for pachinko balls, thereby saving labor in the game hall. We are trying to

The pachinko ball conveyor is a part of the pachinko ball automatic circulation system, and has the function of transporting pachinko balls located at a low place to a high place, and the function of polishing the pachinko balls and removing dirt attached to them. It is a device. The basic structure is that at least an endless belt is rotated, and the rotating endless belt is opposed to the surface of the belt at a distance slightly smaller than the diameter of a pachinko ball. The pachinko balls are held between the support plate and the belt, and the pachinko balls are transported to a high place by the rotational force of the belt. During the conveyance process, the frictional force between the belt and the pachinko balls is used to cause dirt on the pachinko balls to adhere to the belt, thereby completing the cleaning of the pachinko balls at the same time.

Therefore, dirt from pachinko balls continues to adhere to the endless belt, so removing dust from the belt is an essential task. Therefore, the present inventors have already proposed a belt dust remover for a pachinko ball transport machine, which is not disclosed in Japanese Utility Model Publication No. 56-45671.

That is, the dust attached to the belt is removed by the abutting plate that comes into contact with the belt.

[Problems to be Solved by the Invention] However, dust removal using the above-mentioned device also has the following problems, and is still not sufficient.

That is, since the abutment plate is integrally fixed to the dust remover, it is not possible to handle fine movements.

For this reason, the dust removing effect on fine dust adhering to the belt was low, and there was a limit to how clean the belt could be. Furthermore, even if the contact plate is strongly pressed against the belt in order to improve the dust removal effect, the possibility of damaging the pel 1 itself increases, and there is a limit to the dust removal effect due to its structure.

The present invention was developed after intensive study by the inventor in view of the above-mentioned problems, and it is possible to completely remove dust, etc., from any form of dust attached to the belt, and to prevent damage to the belt. The purpose is to provide a bell 1 dust remover for a pachinko ball transfer machine that is free from dust.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the means configured in the present invention includes rotating the belt while removing dust by applying a frictional force between the pachinko balls and the endless belt. In a belt dust remover for a pachinko ball transporting machine that transports the pachinko balls, the belt includes a cover portion that covers a released portion of the belt where contact between the belt and the pachinko balls is released by rotation of the belt; A pachinko machine comprising: a dust removal plate that is rotatably attached to an axis substantially parallel to the width direction of the belt inside the cover part and that comes into contact with a release part of the encasing belt with a predetermined pressing force. The gist of this is the belt dust remover from Tamama Conveyor.

1 Effect] The pachinko ball polishing conveyor in the present invention rotates at least one endless belt to apply a frictional force between the belt and the pachinko balls to remove dust and transport the pachinko balls to a high place. It has the function of Therefore,
Even if it is an endless belt that rotates on one side to hold the pachinko balls and the other side is a fixed plate,
Further, the partner that performs the clamping may be a rotating endless belt, and the clamping may be performed by two rotating endless belts.

As mentioned above, since this is a pachinko ball transporter that transports pachinko balls to a high place while removing dust, its endless belt has two parts: a part that comes into contact with the pachinko balls and transports and removes dust while moving upward; After transportation and dust removal, m
There is always a downwardly moving part, that is, a release part, for holding the pachinko balls.

The cover portion is placed over the released portion of the belt, and has an axis substantially parallel to the width direction of the belt inside the cover portion. A dust removal plate rotatably attached to this shaft is brought into contact with the release portion of the belt with a predetermined pressing force. In other words, only one plate, the dust removal plate, is rotatable and comes into contact with the release part of the belt, and its ability to follow various changes in the belt surface shape, such as undulations caused by belt shape and rotation, is limited. Becomes good. Also,
Since all of the dust scraped off by the dust removal plate is captured by the cover, accumulated dust can be easily cleaned.

EXAMPLES Hereinafter, in order to explain the present invention more specifically, the present invention will be described in detail by giving examples.

[Embodiment] FIG. 1 is a schematic structural diagram of a pachinko ball transporting machine equipped with a dust remover according to an embodiment of the present invention. In the figure, 1 is a pulley rotated by an electric motor (not shown).
A pulley 3 for driving a belt of a pachinko ball conveyor is rotated via a belt 2. An appropriate amount of pachinko balls are flowed by the stopper 4, and when they reach the entrance 5 of the pachinko ball transfer machine, they are held between the conveyance belt 6, which is rotated by the pulley 3, and the outer frame 7 of the pachinko ball transport machine. Thereafter, by the rotation of the belt 6, it is conveyed to the driven pulley 8 above, and cleaning is performed by the force applied to the belt. As a result, the pachinko balls used at the pachinko machine P are returned to the supply box at the top of the pachinko machine P while being cleaned.

Reference numeral 9 is a blower that blows air into the area where the pachinko balls that have been transported by the pachinko ball transporter will fall.
The ori creates a suction air flow that supplements the cleaning action by cleaning the dust that has not yet been removed by the Pachinko Tamama conveyor.

Reference numeral 10 designates the dust remover of this embodiment, which is a downwardly directed part of the belt 6 (hereinafter referred to as the release part) and is designed to cover the part that was holding the pachinko balls (hereinafter referred to as the gripping surface). It is located.

FIG. 2 is an explanatory diagram showing an enlarged and disassembled part of the pachinko ball transfer machine to which the dust remover 10 is attached.

As shown in the figure, the pachinko ball conveyor conveys the pachinko balls T upward by rotating the belt 6 in the direction of the arrow. Four pieces 6a are formed, and consideration is given to making the clamping with the outer frame 7 smoother. As described above, the dust remover 10 is disposed in a part of the released portion of the belt 6. As shown in the figure, the dust remover 10 is mainly composed of two members. The first is a locking member 12 attached to the pachinko ball conveyor, and the second is four single-shaped grooves 12a of the locking member 12 for enclosing the belt 6.
It is covered by a cover 16 that is locked to the cover 16.

To explain each of these members in detail, first, the locking member 12
is a rotatable guide roller 12c between two square columns 12b.
The two hooks are attached directly to the pachinko ball transport machine. The above-mentioned single-shaped grooves 12a are provided at symmetrical positions on each of the square columns 12b.

The two prisms 12b are attached so that their width is wider than the width of the belt 6, and are placed on the guide roller 12C so as to be slidable on the back side of the belt 6 clamping surface. The cover 16 is composed of an outer box 16b made of a highly rigid and transparent synthetic resin, such as polyvinyl chloride resin, which has four locking protrusions 16a for locking onto the locking member 12, and a dust removal plate 16C. has been done. FIG. 3 shows a perspective view of this cover 16 seen from the front, making clear the relationship between the outer box 16b and the dust removal plate 16G. As shown in the figure, the outer box '16b has a dust receptacle 1 below it.
6d, and a dust removal plate 16G is rotatably attached to a shaft 16e slightly above it. The dust removal plate 16C is
A torsion spring 16f and a torsion spring 16f are attached between the outer box 16b and the back surface of the outer box 16b. The front is equipped with a 16g stopper. As a result, the dust removal plate 16C can rotate around lN116e until it is stopped by the front stopper 16C so as to come into contact with the belt 6 with an appropriate pressing force.

The dust remover having the above configuration has the following functions and effects.

That is, although the belt 6 is covered with a dust remover, it rotates smoothly on the guide roller 12C, and accomplishes its purpose of conveying and cleaning the pachinko machine. While the pachinko ball conveying machine is operating as described above, the belt 6 is removed Iα by the dust remover. That is, the dust removal plate 16c, which has a shape at its tip that matches the gripping surface of the bell 1-6, always contacts the belt 6 with an appropriate pressing force due to the elastic force of the torsion spring 16f.

Therefore, all the dust attached to the belt 6 is removed from the dust removal plate 1.
The dust is scraped off by 6G and collected in the dust receiver 16d. Moreover, the dust removal plate 16G is brought into contact with the torsion spring 16f only when the dust removal plate 16G, which has only a small inertial force, is brought into contact with the dust removal plate 16G.
This is achieved by applying a moderate pressing force due to the elastic force of the Therefore, it has excellent ability to follow changes in the belt 6, large and small, such as undulations caused by rotation of the belt 6 or during photographing, and always maintains the specified pressing force without damaging the clamping part of the belt 6. Dust is removed using the .

In addition, as mentioned above, the only part that wears out in this dust remover is the dust removal plate 16G, and it has a simple structure, so
The old dust removal plate 16 whose dust removal effect has deteriorated can be easily replaced, and dust removal from the belt can always be performed well, resulting in excellent handling and economical efficiency.

Furthermore, since the entire dust remover is made of transparent resin, the wear condition of the dust remover plate 16c as described above can be easily seen, and the dust collected in the dust receiver 16d can also be easily confirmed. be.

[Effects of the Invention] As described above in detail with reference to the embodiments, the belt dust remover for the pachinko ball transporting machine of the present invention removes dust by applying a frictional force between the pachinko balls and the endless belt. In a belt dust remover of a pachinko ball transfer machine that rotates a belt to transport the pachinko balls, a cover covers a released portion of the belt where contact between the belt and the pachinko balls is released by rotation of the belt. and a dust removal plate that is rotatably attached to an axis substantially parallel to the width direction of the belt inside the cover part and that comes into contact with the release part of the encasing belt with a predetermined pressing force. That's what I mean.

Therefore, it is possible to always perform the specified dust removal ability without putting any burden on the belt of the pachinko tamama conveyor, which can extend the life of the belt, which is directly related to the service life of the pachinko tamama conveyor. At the same time, it is possible to always maintain the pachinko taming effect of the pachinko taming conveyor in the best condition.
