TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ball polishing pump that removes pachinko balls that have been removed from gaming machines as conveyed balls and that have been conveyed to a collection position by a collection conveyance device, and polish the pachinko balls to an upper tank for recycle supply while polishing them with an endless belt and a polishing cloth. Equipment related.
[0002]
[Prior art]
FIG. 3 is a schematic longitudinal sectional view of a general ball polishing / lifting device, FIG. 4 is a cross sectional view of a portion of the conveyor belt 5 and the door 6 of the conventional ball polishing / lifting device, and FIG. It is BB sectional drawing.
As shown in FIG. 3, the ball polishing / lifting device stretches a transport belt 5 composed of an endless belt on the frame 1 by upper and lower pulleys 2, 3 and intermediate tension pulleys 4a, 4b, 4c in a tensioned state. At the same time, as shown in FIG. 4, an abrasive cloth 8 is supported via a rail body 7 on an inner surface of a door 6 which is attached to the frame 1 on a rising side of a conveyor belt 5 by a hinge and a lock (not shown) so as to be openable and closable. A plurality of ball guide grooves 10 are formed in the polishing pad 8 along the grooves 9 formed in the rail body 7, and when the door 6 is closed at a predetermined position and locked, the ball is collected to the collection position. The pachinko balls P pass through a chute 11 from a ball intake port provided near the lower end of the conveyor belt 5 to pass between the conveyor belt 5 rotated in a predetermined direction and the polishing pad 8 to each of the ball guide grooves 10. Rotated one row at a time While it is pumped, and is configured to be discharged to the upper tank outside the drawing from the upper end of the conveyor belt 5 via the duct 12. In FIG. 3, reference numeral 13 denotes a motor for rotating the driving pulley 3.
[0003]
As shown in FIGS. 4 and 5, the rail body 7 in the conventional apparatus is attached to the back surface of the front plate 6 a of the door 6 directly with an adhesive or by welding 14 on the surface opposite to the side supporting the polishing cloth 8. Had been.
[0004]
[Problems to be solved by the invention]
Since the conventional door has the above-described structure, for example, if the rail body 7 is partially damaged or worn due to a collision of a pachinko ball, only the rail body cannot be replaced. The entire door was replaced or discarded. Therefore, there was a problem in economy.
Further, since the rail 7 is simply fixed to the door 6 by bonding or the like, especially at the joint between the rails of the upper and lower doors, the ball guide groove of the rail of the lower door is moved from the ball guide groove of the upper door. The rail body 7 may be lifted from the door 6 due to the force that may be applied from the pachinko balls P to the rail body when moving to the ball guide groove, so that the pachinko balls are prevented from rising smoothly, There was a risk of jamming between the polishing cloths 8.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and a problem thereof is to provide a ball polishing / lifting device capable of easily performing maintenance at a low cost when a rail body is partially damaged or worn. Is to provide.
[0006]
[Means to solve the problem]
In order to solve the above-described problems, the present invention includes a frame that supports a transport belt that is rotated in a predetermined direction by a motor, and a door that is openably and closably attached to the frame, and the door is closed. In the state, while holding the polishing cloth to be polished while rotating the pachinko balls between the conveyance belt and the lifting surface of the conveyance belt, a plurality of grooves forming pachinko ball guide grooves are formed on the polishing cloth. In a ball polishing / lifting device having a rail body provided, the rail body is attached to a mounting plate, and the mounting plate is assembled to the door by separable fixing means.
When the rail body is damaged by the above configuration, remove the polishing cloth from the door, operate the fixing means for attaching the mounting plate to the door, remove the mounting plate from the door, and mount the mounting plate and the rail body. Only can be replaced.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, the form of the actual paper of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a portion of a conveyor belt and a door of a ball polishing and feeding apparatus according to the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG. The same reference numerals are used for the same members as those of the conventional apparatus shown in FIG.
Referring to FIG. 1, in the ball polishing / lifting device according to the present invention, the rail body 7 is attached to a thin flat mounting plate 15 by an adhesive or welding. The mounting plate 15 has a height equal to the height of the door 6, extends outward from both ends in the width direction of the rail body 7, and has a hole at an arbitrary vertical position in the extending portion. It is provided.
The front wall 6a of the door 6 is also provided with holes at positions matching the holes of the mounting plate. Then, by attaching the mounting plate 15 to the inner surface of the front wall 6a of the door 6 and screwing the screw 16 into the aligned hole, or by fixing it with separable fixing means such as a bolt and nut, the rail body 7 is moved. 6 fixed.
[0008]
In a preferred embodiment, as shown in FIG. 2, an L-shaped engaging groove 17 is formed at the lower end of the rail body, and an L-shaped locking metal 18 is fixed to the lower end of the mounting plate 15. When the pachinko ball P may apply a pressing force to the lower end of the rail body 7 by engaging the locking member 18 with the engaging groove 17 when the rail body 7 is fixed to the door 6, The lifting of the rail body 7 is thereby effectively prevented.
[0009]
With the above configuration, when the rail body 7 is damaged or worn by the force applied to the rail body 7 by the cooperative action of the transport belt 5 and the pachinko balls P, the fixing means (16) is operated. Thus, the rail body 7 can be easily separated from the door 6. Therefore, only the rail body 7 can be replaced, and the door can be used continuously.
[0010]
【The invention's effect】
As described above, according to the present invention, the rail body carrying the polishing cloth is attached to the mounting plate, and the mounting plate is attached to the door so as to be separable by the fixing means, so that only the rail body can be replaced. , The economy is improved.
