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.

C. Prior Art Conventionally, pachinko game halls have adopted an automatic pachinko ball circulation system that automatically transports a large number of pachinko balls using a power source to form a supply route for pachinko balls, thereby saving labor at the game hall. We are trying to make this happen.

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 conveyed 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 conveyor shown 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.

In other words, the above-mentioned device that uses a contact plate to remove dirt adhering to the belt is effective against dirt adhering to the surface of the belt in a convex manner, but it is effective against dirt adhering flatly to the surface of the belt. However, there is a limit to its ability to remove dust, and since a frictional force is applied between the belt and the contact plate, there is a possibility that the belt may be damaged.

The present invention was developed after intensive study by the inventor in view of the above-mentioned problems, and is capable of completely removing dust, etc., from any form of dust attached to the belt. The purpose is to provide an excellent belt dust remover for a pachinko ball transfer machine that does not impose any burden.

[Means for Solving the Problems 1] In order to solve the above-mentioned problems, the means constituted by 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 of a pachinko ball transporter that transports the pachinko balls, an air flow is forcibly created in a released part of the belt where the belt and the pachinko balls are released from contact by rotation of the belt. The gist of this invention is a belt dust remover for a pachinko ball transport machine, which is characterized by being equipped with an air flow generator.

[Function] The pachinko ball 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 move the pachinko balls to a high place. It has a transport function. Therefore, even if one side for holding pachinko balls is a rotating endless belt and the other side is a fixed plate, the partner that holds the pachinko balls is a rotating endless belt and their rotational speeds are different. It can be any of the following.

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 such transportation and dust removal, there is always a part that moves downward to grip the pachinko balls again, that is, a release part.

The airflow generating section is a device that forcibly creates an airflow in the released portion of the belt. The method for creating the airflow may be either by intermittently blowing compressed air or by rotating a fan to continuously create the airflow.

In addition, the air flow removes dirt adhering to the release part of the belt, so the relationship between the air flow and the release part of the belt is that the surface of the belt that was in contact with the pachinko balls (the surface ), or one that uses airflow from the back side of the belt to the front side to peel off the dirt from the belt, which can be selected as appropriate depending on the type of dirt that adheres to the belt. It will be adopted as follows.

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 rotationally driven 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 moved by the conveyance belt 6 rotated by the pulley 3 and the outer frame 7 of the pachinko ball transfer machine. It is held and then conveyed to the upper driven boob 98 by the rotational movement of the belt 6, where it is cleaned by the frictional force with the belt. As a result, the pachinko balls used in the pachinko machine P are cleaned and returned to the supply box at the top of the pachinko machine P. Creates a blowing or suction air stream to the falling area.

This cleans the dust that has not yet been removed by the pachinko tamash conveyor, thereby supplementing the cleaning effect.

Reference numeral 10 designates the dust remover of this embodiment, which includes a filter 12 for filtering the air taken in from the suction port 11 facing the surface of the belt 6, a fan 13 for creating such an air flow, and the suction port 11. The dust collecting section 14 collects dust and the like sucked into the dust remover 10.

Although the configuration is simple as described above, according to the dust remover of this embodiment, the air flow in the direction of the arrow in the figure generated by the fan 13 has a large flow velocity near the suction port 11 where the flow diameter is narrow. . Therefore, near the release part 6' of the belt 6, a strong wind blows from the back side of the belt toward the surface that was in contact with the pachinko balls, and all the dirt and other impurities attached to the belt are removed by the dust remover. Inhaled within 10 minutes.

Among the dust sucked in in this way, those with a large weight fall directly into the dust collection section 14, and those with light weight fall into the dust collection section 14 after being filtered by the -H filter 12. Dust removal from the belt 6 can be easily completed by periodically removing the dust accumulated in the dust collecting section 14.

Further, there is no need to provide a separate power source for the fan 13, and if the rotational power is obtained from an electric motor that rotates the pulley 1, which is the drive source for the pachinko ball transport machine, the pachinko ball transport machine will operate. Since the dust remover 10 operates only when the belt 6 rotates, the operating rate can be increased.

Furthermore, according to the dust remover 10 of this embodiment, dust removal can be performed without contacting the belt 10;
If the belt 10 is made of a strong material that will not be damaged by contact, and if the dust etc. adhering to the belt 10 is strongly adhesive, the belt 6 in the figure may be replaced as necessary.
A brush or the like that comes into contact with the surface of the belt is placed near ′.
It may also be configured such that the dust is mechanically removed from the belt to make it easy to inhale and then sucked in by the dust remover 1o.

In this way, the dust remover 10 of this embodiment can easily remove dust without placing any burden on the belt.

FIGS. 2 and 3 show the relationship between a dust remover and a belt for removing dust in another embodiment.

First, the dust remover 20 in FIG. 2 is configured to use a compressor 21 to suck in air on the right side of the figure as shown in the figure while filtering it through a filter 22 and compress it. Air is intermittently blown from the air outlet 23 located in the air. Therefore, the compressor 21 is disposed on the back side of the belt 24, and on the front side thereof, a dust collecting section 25 that collects dust etc. separated by the intermittent air flow is opened opposite to the air outlet 23. Ori,
All dust and the like are removed by this dust collecting section 25. Note that 26 is a filter that filters the airflow so that dust and the like attached to the belt 24 are not scattered outside.

According to this embodiment, since dust and the like can be removed by the air flow from the back side, the breathable belt 2
It is most effective for removing dust in step 4.

Furthermore, since the compressor 21 compresses air to create an air flow, and the outlet 23 is narrowed, a large flow rate can be easily created, further increasing the dust removal effect.

FIG. 3 shows a dust remover 30 that similarly uses compressed air to remove dust from a non-permeable belt. In the figure, 31 is a compressor, which compresses air filtered through a filter 32 and discharges it from an outlet 33. The air outlet 33 is formed at an acute angle with respect to the surface of the belt 34, and the air hitting the surface of the belt 34 and the dust separated by the air enter the dust collecting section 35.

Of these, only the air is filtered through the filter 36 and exits from the dust remover 30 to the outside. This embodiment is particularly effective for removing dust from belts that do not have air permeability.

In addition, the compressor 2 of the embodiment shown in FIGS. 2 and 3
1.31 may be used as a normal fan to generate a continuous air flow, and the air flow generator may operate only when the belt 24.34 rotates as described in the previous embodiment. Belt for good 24.
It is preferable to share an electric motor or the like which is the drive source for the 34 units.

Further, in order to improve the dust removal effect, if the surface portion of the belt where the air flow is generated is mechanically removed with a brush or the like, the dust removal effect will be further improved.

As explained above, according to the dust remover of this embodiment, dust removal can be completed without contacting the belt at all, and the life of the belt is extended because no load is placed on the belt. The pachinko ball polishing effect of the belt can always be maintained in its best condition.

[Effects of the Invention J] As described above in detail with reference to the embodiments, the belt dust remover for the pachinko ball transporter of the present invention removes dust by applying a frictional force between the pachinko balls and the endless belt while removing the dust. In a belt dust remover of a pachinko ball transfer machine that rotates a belt to transport the pachinko balls, an air flow is introduced into a released portion of the belt where the contact between the belt and the pachinko balls is released by the rotation of the belt. This device is characterized by having an airflow generating section that is forcibly created.

Therefore, dust removal from the belt can be completed without any contact with the pachinko tamama conveyor, so there is no load on the pachinko tamama conveyor, and the life of the belt can be extended and the belt can always be removed. The pachinko taming effect of the pachinko taming conveyor can be maintained in the best condition.
