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.

[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 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 inventors of the present invention
We have already proposed a belt dust remover for a pachinko ball conveyor shown in Japanese Patent No. 45671.

That is, dust and the like adhering to the belt are removed by the abutting plate that comes into contact with the belt.

[Problems to be Solved by the Invention] However, the dust removal using the above-mentioned device also caused the following problems and was 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 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] As a means for achieving the above object, the belt dust remover for the pachinko ball conveyor of the present invention removes dust by applying frictional force between the pachinko balls and the dust removal surface of the endless belt. In a belt dust remover for a pachinko ball transporting machine that rotates the belt while conveying the pachinko balls, the belt is removed from contact with the pachinko balls by the rotation of the belt. an air flow path that forms an air flow through the dust removal surface of the belt at the release portion; an air flow generating means that is interposed in the air flow path and forcibly creates an air flow; and a filter disposed downstream of the dust removal surface of the belt to collect dust in the air flow, and the air flow path has a reduced diameter portion of the flow path near the dust removal surface of the belt. The gist is:

[Function] The pachinko ball conveyor in the present invention rotates at least one endless belt,
It has a function of conveying the pachinko balls to a high place while removing dust by applying a frictional force between the belt and the pachinko balls. 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 the rotation speeds are different. It can be any of the following.

As mentioned above, the pachinko ball removal machine has a structure that transports the pachinko balls to a high place while removing dust, so its endless belt has two parts: one part that contacts the pachinko balls and moves upwards to transport and remove dust. 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 belt dust remover for the pachinko ball conveying machine of the present invention forms an air flow through the dust removal surface of the belt that conveys pachinko balls by applying frictional force at the above-mentioned belt release portion. The air flow formed here is forcibly created by the air flow generation means, and the flow speed is increased at the reduced diameter portion of the flow path near the dust removal surface. The accelerated air flow is blown onto the dust removal surface in the vicinity of the reduced diameter portion, passes over the dust removal surface, or sucks air onto the dust removal surface. This removes the dirt adhering to the dust removal surface.
The peeled off dirt is swept downstream with the airflow and collected by a filter.

Therefore, dirt is peeled off from the dust removal surface without coming into contact with the belt, and is collected by the filter. Moreover, the dust separated from the dust removal surface is collected without covering the entire belt.

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, reference numeral 1 denotes a pulley rotatably driven by an electric motor (not shown), which rotates a belt-driving pulley 3 of a pachinko ball conveyor 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 transport machine, they are transferred to the transport belt 6 rotated by the pulley 3 and the outer frame 7 of the pachinko ball transport machine. Thereafter, it is held and then conveyed to the upper driven pulley 8 by the rotational movement of the belt 6, and is cleaned by the frictional force with 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 denotes a blower, which generates a blowing or suction air flow to the area where the pachinko balls transported by the pachinko ball transporter fall. In this way, the dust that has not yet been removed by the Pachinko Tamashi conveying machine is cleaned, and the cleaning effect is supplemented.

Reference numeral 10 designates the dust remover of this embodiment, which includes a filter 12 for filtering the air sucked in from the suction port 11 facing the dust removal surface on the surface of the belt 6, a fan 13 for creating such an air flow, and It is comprised of a dust collecting section 14 that collects dust and the like sucked into the dust remover 10 through the suction port 11. Inlet 11
is a reduced diameter portion of the air flow path formed by the dust remover 10. Filter 12 is located downstream of the dust removal surface.

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. becomes. Therefore, near the release part 6' of the belt 6, a strong wind blows from the back side of the belt toward the dust removal surface that was in contact with the pachinko balls, removing all the dirt and other dirt that had adhered to the belt. The dust is sucked into the dust remover 10. 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 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 force is obtained by an electric motor that rotates the pulley 1, which is the drive source of the pachinko ball transfer machine, the pachinko ball transfer machine can be operated. Since the dust remover 10 operates only when the belt 6 rotates, the operating rate can be increased.

Further, according to the dust remover 10 of this embodiment, dust removal can be performed without contacting the belt 6, but the belt 6 is made of a strong material that will not be damaged by contact. If the dust adhering to belt 6 is highly adhesive, etc., a brush or the like that comes into contact with the belt surface may be placed near belt 6' in the figure as necessary, and mechanically removed. It may also be configured such that the dust is removed from the belt and made into a state where it can be easily inhaled, and then sucked in by the dust remover 10.

In this way, the dust remover 10 of this embodiment can easily remove dust without placing any burden on the belt. Furthermore, the entire belt 6 can be removed and collected by simply attaching the dust remover 10 to a portion of the belt 6 without covering the entire circumferential range with a cover or the like, and the number of parts and size can be reduced.

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 shown in FIG.
1, after the air on the right side of the drawing is filtered by a filter 22, sucked in and compressed, air is intermittently blown from the air outlet 23 whose diameter is reduced in order to increase the flow velocity of the air flow as described above. It is something. Therefore, this compressor 21 is disposed on the back side of the belt 24, and on the dust removal surface on the front side, a dust collecting section 25 that collects dust etc. separated by intermittent air flow is opposed to the air outlet 23. The dust collection section 25 has an opening, and all dust and the like is removed by this dust collecting section 25. Note that 26 is a filter located downstream of the dust removal surface in the air flow path, and is used to filter the air flow so that dust and the like attached to the belt 24 are not scattered to the outside.

According to this embodiment, dust and the like can be removed by the air flow from the back surface, so that it is most effective for removing dust from the breathable belt 24.
Moreover, since the air is compressed by the compressor 21 to create an air flow, and the outlet 23 is narrowed, a large flow velocity 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, and a filter 32
Compress the filtered air through the air outlet 3
Discharge from 3. The air outlet 33 is formed at an acute angle with respect to the surface of the belt 34, and air hitting the surface of the belt 34 and dust separated by the air enter the dust collecting section 35.
Of these, only 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.

Furthermore, the compressors 21 and 31 of the embodiment shown in FIGS. 2 and 3 may be used as ordinary fans to generate a continuous air flow, and the operation of the compressors 21 and 31 of the embodiment shown in FIGS. Since it is necessary to perform this operation only when the belts 24 and 34 rotate, it is preferable to share the drive source of the belts 24 and 34, such as an electric motor.

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] As described above in detail with reference to the embodiments, the belt dust remover for the pachinko ball conveyor of the present invention removes dust on the dust removal surface using the air flow whose flow velocity is increased by the reduced diameter part. Remove and collect dust.

Therefore, dust removal from the belt can be completed without any contact with the pachinko tamashi conveyor, so there is no load on the pachinko tamashi conveyor, and the life of the belt can be extended. At the same time, the pachinko taming effect of the pachinko taming conveyor can always be maintained in the best condition. Moreover, it is possible to remove dust from the entire belt and collect the generated dust by disposing it in a part of the belt rotation range without covering the entire belt with a cover etc., which reduces the number of parts and makes it compact. can be achieved.
