Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pachinko ball lifting and polishing device that transports dirty pachinko balls while polishing them with granular abrasive grains such as synthetic resin, and in particular, the present invention relates to a pachinko ball lifting and polishing device that transports dirty pachinko balls while polishing them with granular abrasive grains such as synthetic resin. The present invention relates to an abrasive grain cleaning device for cleaning.

An example of an apparatus for transporting pachinko balls while polishing them with abrasive particles is described in Japanese Patent Publication No. 4546/1983.

The above-mentioned conventional lifting polishing device has the advantage that the upright lifting cylinder can be installed freely in a narrow pachinko island without taking up much space.
The problem was that the pachinko ball and abrasive grains at the bottom were difficult to introduce, but by bending the bottom in an arc shape, we made it easier to introduce and exhibited stable performance. However, in recent years, with the spread of pachinko machines equipped with large-sized games, the flow of pachinko balls at game parlors has increased dramatically, and it is now necessary to handle a much larger number of balls than before. However, it had a structural weakness that made it difficult to improve its capabilities beyond that of the past. In addition, since it absorbs dirt from pachinko balls and circulates the dirty abrasive particles as is, it also has the disadvantage that its cleaning ability decreases significantly over time.
After a pachinko parlor closes, the dirty abrasive grains must be taken out and washed regularly in a washing machine, which places a heavy burden on the pachinko parlor.

The present invention has solved the above-mentioned conventional drawbacks, and its purpose is to handle the flow rate of pachinko balls, which has increased dramatically due to the spread of large-scale games in recent years. By arranging the cylinders in an L-shape and driving and rotating the spiral bodies inserted separately in each cylinder, it is possible to stably increase the processing capacity, and also to prevent the abrasive particles from becoming contaminated. The abrasive grain cleaning device installed in the lifting polishing device converts the flow of abrasive grains and allows them to be easily cleaned and returned to each pachinko island without the need for manpower when necessary. I made it possible.

A cleaning circulation pipe 17 is provided to communicate with the abrasive grain cleaning device 16, and a delivery gutter 19 of the abrasive grain cleaning device 16 is connected to the abrasive grain storage tank 8.

Further, a current changing mechanism 18 is provided to change the flow direction of the abrasive grains b to the circulation pipe 15 and the clean circulation pipe 17, and the current changing mechanism 18 circulates the abrasive grains b flowing down from the abrasive grain tray 12 as necessary. The pipe 15 is converted into a cleaning circulation pipe 17 and introduced into the abrasive grain cleaning device 16.

Further, a dust absorption box 21 having a mesh plate 20 stretched on the surface is provided in the sorting device 10, and the dust absorption box 2

The lifting polishing device with an abrasive grain cleaning device according to the present embodiment has the above-described configuration. It flows from the gutter 7 and from the abrasive grain storage tank 8, and is forced into the lower part of the transport cylinder 1 while being mixed and stirred by the rotation of the spiral body 6,
A mixture of pachinko balls a and abrasive grains b, which are successively pushed, is lifted and polished by a lifting cylinder 1. Therefore, the pachinko balls a and the abrasive grains b can easily flow into the cross-feeding tube 2, and the mixture is forced into the lower part of the lifting tube 1 by the cross-feeding tube 2 and Since it is introduced into

When the upper discharge port 9 is lifted, the upper discharge port 9
Pachinko balls a flow into the sorting device 10 temporarily installed in
The pachinko balls a are separated into the abrasive grains b and the abrasive particles b, and flow down into the supply gutter 14, where they are used as supply balls for the pachinko machine. On the other hand, the abrasive grains b are collected in the abrasive grain receiver 12 of the sorting device 10, and are returned to the cross-feeding cylinder 2 through the circulation pipe 15 connected to the abrasive grain receiver 12, where they are mixed with the pachinko balls a again, and are stirred and pumped. Since it is used for polishing, the surface of the abrasive particles b gradually becomes dirty over time due to repeated use, and the cleaning ability decreases.

Therefore, the flow direction of the abrasive particles b which are being returned to the dirty abrasive particles b through the circulation pipe 15 is changed to the clean circulation pipe 17 by the current changing mechanism 18. It was designed so that it could be introduced into 16 areas for cleaning.

The abrasive grain cleaning device 16 includes a cleaning outer shell 27 installed horizontally, a screw section 25 and an agitating section 26 installed in the cleaning outer shell 27, and a cleaning rotor that is rotated horizontally by a drive motor 24.

The outer covering part 30 is formed from a through hole that is finer than the abrasive grains b provided on the stirring part 26 side.
The dust c that falls on the outer cover part 30 and is collected by the suction hose 31 connected to the dust collector 22 is collected by suction.

Although the present invention has been described above based on the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed. can. For example, although the clean circulation pipe 17 is branched from the circulation pipe 15 from the outlet of the sorting device 10, it may be branched from the middle of the circulation pipe 15, and the current transformation mechanism 18 is also limited to the embodiment shown in the drawings. Any mechanism that can convert the abrasive grains b flowing down into the circulation pipe 15 into the clean circulation pipe 17 as necessary and convert them into the circulation pipe 15 when cleaning is not required is sufficient. be.

In summary, the present invention provides a pumping and polishing device that mixes pachinko balls with abrasive grains and agitates and polishes them while transporting the balls, which is equipped with an abrasive grain cleaning device for cleaning dirty abrasive grains separately and connected to a circulation pipe. A cleaning circulation pipe was also installed, and the flow direction of both circulation pipes could be changed as necessary so that the abrasive particles could be introduced into the abrasive particle cleaning device for cleaning.
Even after the pachinko parlor is closed or even during business hours, each lifting device can be cleaned to remove dirt from abrasive particles when necessary.
In addition, the flow direction of the two adjacent circulation pipes can be easily changed using a current changing mechanism, so if the abrasive grains are not contaminated, they can be directly refluxed through the circulation pipe, and even if they are contaminated to some extent. In the current state, it is converted to the cleaning circulation pipe side and introduced into the abrasive grain cleaning device for cleaning, so there is no need to periodically take out the abrasive grains and wash them or replace them, as with conventional pumping polishing equipment. Moreover, since the abrasive grains are cleaned only when necessary, the abrasive grains are not wasted by unnecessary cleaning.

In addition, the abrasive grain cleaning device cleans the abrasive grains by pushing the abrasive grains flowing in from the supply port of the cleaning outer shell one after another to the stirring part side by the screw part rotating inside the cleaning outer shell, and The abrasive grains are stirred and cleaned by stirring and rubbing against each other, so, for example, in a rice polishing machine, brown rice is stirred and polished without damaging the rice grains due to the friction between the brown rice. Rather than cutting or polishing by bringing the polishing machine into direct contact with the abrasive grains, dirt adhering to the surface is rubbed off and cleaned by mutual friction, so there is no chance of damaging or breaking the abrasive grains. without compromising durability.

In addition, the abrasive grain cleaning device of the present invention has a simple structure in which the main components are a cleaning outer shell disposed horizontally and a cleaning rotation mechanism that rotates inside the cleaning outer shell, making it robust and compact. Even if it is installed together with a lifting polisher on a narrow pachinko island with little dimensional space, it does not require special space and can be easily installed within the range that a conventional lifting polisher can be installed. It is.

In addition, since the abrasive grain supply port is provided in the clean outer shell installed horizontally, there is no need for a special additional mechanism for inflowing the abrasive grains flowing back from the clean circulation pipe. The abrasive grains do not flow in without limit, but are restricted by the screw part of the cleaning rotation mechanism that rotates within the cleaning outer shell, and are taken in according to their conveyance capacity and sequentially pushed toward the stirring part. An appropriate amount of abrasive grains are constantly introduced into the cleaning outer shell, and uniform cleaning is performed in accordance with the cleaning capacity.

As mentioned above, in the present invention, as pachinko machines equipped with large-scale games have appeared and become widely popular, the flow of pachinko balls in game parlors has increased dramatically, and a large amount has also been distributed on each pachinko island. However, by arranging the cross-feeding tube in an L-shape below the lifting tube, the biggest weakness of the upright-shaped lifting tube was eliminated. The difficulty of introducing pachinko balls and abrasive grains in the hot lower part has been stably and greatly improved, and the ball processing capacity has been increased while taking advantage of the advantages of the upright transport tube. As a result, the abrasive grains that are used in circulation and must be polished and cleaned in large quantities become more heavily contaminated in response to the increased processing volume, reducing the polishing and cleaning power. By installing an easy-to-install abrasive grain cleaning device on the machine, each pachinko island can be easily cleaned and refluxed when necessary depending on the dirtiness of the abrasive grains, without the need for manpower. We have achieved a lift polishing device that has both processing and polishing capabilities that can handle the flow of pachinko balls that has been increasing in recent years.
