DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for conveying and polishing pachinko balls.

[0002]

2. Description of the Related Art A so-called lift-type polishing apparatus is conventionally known as this type of pachinko ball transfer polishing apparatus. This lift type vertical polishing apparatus is disclosed in
As shown in Japanese Patent No. 25365 and Japanese Utility Model Application Laid-Open No. 2-25288, the guide member has a gutter groove through which a pachinko ball passes, and a transport belt that transports the pachinko ball while pressing the pachinko ball on the gutter groove side. is there.

[0003] That is, pachinko balls are in accordance with the rotation of the endless belt, in the process of being conveyed in trough grooves from the lower inlet side to the upper outlet side, is cleaned by adhering the dirt on the endless belt, The pumped pachinko balls are supplied to each pachinko machine. In this case, the endless belt is washed at an appropriate time, usually every day.

[0004] On the other hand, a large number of small cylindrical polishing beads are put into the gutter groove, and the pachinko balls are polished by the contact with the polishing beads, and finally discharged from the outlet as polished pachinko balls. On the other hand, it is also known that the abrasive beads, after being separated from the pachinko balls, are introduced into the gutters for reuse and are configured to circulate for a period of time until the dirt reaches a limit.

[0005]

However, in this conventional polishing apparatus, it is fundamental to transfer dust, dirt, oil and the like adhering to pachinko balls to an endless lifting belt or polishing beads. When the belt or the polishing beads become heavily soiled after a long operation, the belts or the polishing beads have to be washed and reused or replaced with new ones. Also, in the case of using abrasive beads, it is necessary to transfer the dirt to a cloth transport (transport) belt, remove the transport belt from the polishing apparatus, and wash frequently. For this,
For pachinko parlors, it was necessary to perform cleaning after business hours, which was a heavy burden.

Accordingly, it is a main object of the present invention to provide a pachinko ball having an excellent polishing effect, and to eliminate or reduce the frequency of cleaning of the conveyor belt, thereby enabling a substantially continuous operation.

[0007]

Means for Solving the Problems The present inventor obtained the following knowledge in the course of studying a drastic solution in order to solve the above-mentioned problems of the conventional polishing apparatus.

That is, in the conventional polishing apparatus, since both sides of the pachinko ball path are continuous over the entire feeding distance, dirt and dust do not escape and adhere to at least one of the guide path and the transport belt. things der
You. Therefore, if a path is formed in the guideway that constitutes the wall to allow dust and moisture to escape to the opposite side of the pachinko ball path,
We noticed that the dust of the pachinko balls that were sequentially introduced was not accumulated.

For this purpose, if a suitable hole is formed in the guide path, for example, dust and moisture escape from the hole. However, in addition to dust that easily falls off the pachinko balls, moisture that retains them, tobacco tar, sweat, and fat on the skin of the hands are firmly attached to the pachinko balls, making it extremely difficult to remove them. It is. Regarding moisture, it has been empirically found that, particularly during the rainy season, poor transport of pachinko balls occurs.

[0010] Therefore, not only to remove dust and moisture, without using an abrasive medium such as polishing beads, scrape forcing the dirt guideway itself scheme suitable der
I arrived at the idea. For this purpose, in the present invention, an interval for polishing is formed, and a square edge is formed in the interval.

That is, according to the present invention, a plurality of conveying guide members are provided in the moving direction of the pachinko balls, and a guide path is formed by providing a dirt discharging interval at least in the pachinko ball moving portion between the guide members. Opposite this guideway
And put the conveyor belt at intervals to interpose pachinko balls.
The pachinko ball is conveyed while rolling the pachinko ball by the movement of the transport belt while resiliently pinching the pachinko ball between the guide path and the transport belt, and rolling the pachinko ball of the guide member. The gist of the present invention is a pachinko ball conveying and polishing apparatus characterized in that the edge in the moving direction of the surface is square.

Here, it is desirable that the downstream edge in the moving direction of the rolling surface of the pachinko balls is formed at an acute angle, and the interval for discharging dirt is preferably 0.5 mm to 7 mm.

[0013] It is desirable that the dirt discharging interval portion communicates with the back side of the guide member. Further, the pachinko ball moving portion can be formed by a gutter along the moving direction.

[0014]

In the present invention, the guide path is formed with a dirt discharging interval at least in the pachinko ball moving portion between the guide members. Therefore, at least a part of the dust falls into the dirt discharging interval. In this case, under the preferred embodiment, the dirt discharging interval portion communicates with the back side of the guide member. As a result, the dust that has fallen within the dirt discharge interval escapes to the rear side of the guideway. Moisture escapes as well.

However, as described above, moisture, tobacco tar, sweat, fat on the skin of the hands, and dirt which are integrated with dust adhere to the pachinko balls firmly. Difficult to remove. Therefore, the edge in the moving direction of the rolling surface of the pachinko ball of the guide member that forms the polishing interval is formed in a square shape. As a result, as is clear from the description with reference to the drawings described later, in the rolling process of the pachinko ball, the dirt attached to the pachinko ball is relatively scraped off by the edge, and the dirt is removed. . The removed dirt gradually enters the dirt discharge interval, and accumulates there or escapes to the rear side. Therefore, in the moving portion (rolling portion) of the pachinko balls and the conveying belt portion, substantially no dirt remains, and polishing can be continuously performed without cleaning for a long period of time.

[0016]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 and FIG. 2 show the entirety of a lift-type polishing apparatus of the present invention provided at, for example, a center portion of an island of a pachinko machine, and a conveying guide member 2 provided on a vertical housing 1. An endless cloth-made transport belt 3 is disposed opposite to the guide path constituted by the groups. The transport belt 3 is wound around upper and lower drums 4 and 5, and the lower drum 5 rotates an output shaft of a drive motor 6 via a drive belt 7.

The dirt pachinko balls B0 are introduced into the entrance 8 and guided between the guide member 2 and the conveyor belt 3, and are pressed upward by the pressure of the pachinko balls by the relative resilient pressure and the conveying force of the conveyor belt. It is conveyed, and in this process, it is polished as described later, and is discharged from the outlet 9 as polished pachinko balls B1. Reference numeral 1A denotes a main body side plate as a structural material. The detachable metal fitting 1B is detached, the housing 1 is detached, and the inside of the housing 1 is disassembled or facilitated when necessary. Housing 1
Is removed, the conveyor belt 3 is exposed.

In the present invention, the guide member 2 is formed of a material exhibiting abrasiveness as the pachinko ball moves (slids or rolls). For example, a hard or soft plastic mixed with a pigment or abrasive powder, a roughened surface, or the same material as conventional abrasive beads can be used. Further, it may be made of ceramics or the like. As more specific examples of these materials, nylon 66 (trade name), polyacetal resin, high-density polyethylene, or 10 to 50%
And the like can be mentioned.

The guide member 2 may be formed by forming an appropriate number, for example, 5 or 10 gutter grooves 20 having a semicircular cross section in the width direction. The length of the guide member 2 in the moving direction of the pachinko balls is preferably about 7 to 300 mm, particularly about 10 to 50 mm, in order to enhance the polishing action per transfer.

Detailed examples of the guide member 2 are shown in FIGS. That is, in the embodiment, in the width direction of the guide member 2 (the direction orthogonal to the transport direction), the movement of the pachinko ball, which is a semicircle of, for example, 11.2 mm, which is slightly larger than the diameter of the pachinko ball (11 mm). A gutter groove 20 constituting a (rolling) portion is formed along the transport direction. As shown in FIG. 6, the vertical cross section of the guide member 2 in the transport direction is formed as a slope, for example, a parallelogram having a slope angle θ of 30 degrees.

In FIG. 6, the pachinko balls are conveyed while rolling in the direction of the arrow shown in the figure. The inclined surface 21 in the downstream direction in the conveying direction is a sharp surface that is not chamfered, whereas On the inclined surface 22, the entrance of the gutter groove 20 is chamfered 23, so that the pachinko balls are smoothly guided. Further, as clearly shown in FIG. 4, the inclined surfaces 22 are obliquely entered from the adjacent gutter grooves 20 and extend in the thickness direction (up and down direction in FIG. 4) in a gathered state. A Y-shaped discharge groove 24 is formed. Also, locking portions 25, 2 are provided at both ends in the width direction of the guide member.
5, and a downflow slit 26 is formed at a position corresponding to the discharge groove 24 on the back surface.

The guide members 2, 2,... Are, as shown in FIG.
It is held therein via a repulsion spring 27. One end of the repulsion spring 27 is connected to a cylindrical hole 28 on the back of the guide member 2.
And the other end is in contact with the bottom surface of the housing 1,
The guide member 2 is pressed against the conveyor belt 3. The locking portions 25, 25 of the guide member 2 are
A, 1A is abutted to prevent falling off.

Under such a configuration, as described below, the pachinko balls are conveyed and polished. That is, the pachinko ball B0
The pachinko ball B0 and the conveyor belt 3 are pressed against each other in order to surely lift up. In this embodiment, the guide member 2 is pressed against the conveyor belt 3 by a repulsion spring 27 provided between the guide member 2 and the housing 1. so,
Since the gutter groove 20 is stretched through the pachinko balls B0 with a short interval therebetween, a strong pressing force acts on the pachinko balls B0.

In the present invention, in the process of rolling and transporting the pachinko balls B0 by the transport belt 3, the dirt D is polished or removed at the edge 21A of the inclined surface 21 in the gutter groove 20 portion.

This process will be described with reference to FIGS.

That is, the pachinko ball B0 rolls and moves from the left side in FIG. With this movement, for example, FIG.
As described above, when the pachinko ball B0 reaches the second guide member 2, the pachinko ball B0 is pressed by the housing 1 toward the housing 1 and moves to the rear side. Further, as shown by the imaginary line in FIG.
In the process of shifting from the second guide member 2 to the third guide member 2, the third guide member 2 is sequentially pushed down.
As the rolling conveyance of the pachinko balls progresses, there is a stage where the bottom level of the gutter groove 20 coincides in the middle of the transition, and as the rolling progresses further, as shown in FIG. Restoration to the conveyor belt 3 side gradually progresses.
Therefore, a step is formed between the second guide member 2 and the third guide member 2. Since the pachinko ball B0 rolls in the process of the occurrence of this step, the inclined surface 2 of the second guide member 2
The edge 21A of one has an effect of relatively shaving the surface of the pachinko ball B0, and as a result, the dirt D is removed by the edge 21A. Such an operation of removing dirt is performed each time the member passes through each of the guide members 2, 2,.... As a result, the abrasive ball B1 is discharged from the outlet 9.

The interval L for discharging the dirt D in the present invention is:
This is for allowing the dirt D to flow out of the gutter 20 to the back side. Therefore, in the above embodiment, the discharge groove 2
Reference numeral 4 denotes an interval L for discharging the dirt D. However, for example, as shown in FIG. 10, the guide member 2 of the slide strip 29, 29 formed at both end portions of the inclined surface 22 on the upstream side, between the slide strip dirt protruding thickness of the 29 and 29 min D for discharge
And interval L, without inducing stains fraction D from Kakutoimizo 20, 20, directly within that interval, can flow out to the rear side. In any case, between the dirt discharge D
The distance L is preferably 0.5 to 7 mm. If the length is short, the effect of discharging the dirt D is small and clogging occurs. Conversely, if the length is large, it is difficult to form a step in the state shown in FIG. This is because the effect is reduced.

Further, the removed dirt D is discharged to the dirt D.
In addition to the use interval L , for example, as shown in FIG. 11, a discharge hole 30 communicating with the back surface may be formed in the middle of the guide member 2 so as to discharge from the discharge hole 30.

The interval L for discharging the dirt D does not necessarily have to communicate with the back side, and may be closed halfway. In this case, the dirt D is sequentially discharged for dirt D.
Since it accumulates within the interval L , it can be decomposed and the accumulated dirt D can be removed, for example, at the stage when about one month has passed.

In the above embodiment, the pachinko balls are conveyed through the gutter grooves 20, but even if the rolling surface of the pachinko balls is a mere flat surface having no gutter grooves, the effect of scraping off the dirt D is similarly exerted. The angle θ of the inclined surface 21 is preferably 10 to 45 degrees. However, it has been confirmed by an experiment that there is an effect of scraping the dirt D up to minus 30 degrees. When the angle θ is small or in the minus direction, the scraping effect is not sufficient, and when it is more than 45 degrees, there is a problem in terms of edge durability. The edge of the inclined surface 21 is desirably as sharp as possible from the point of the shaving effect, but in some cases, chamfering in a range of about 1 mmR can be performed.

In the present invention, conventional polishing beads are not basically used, but they can be used if necessary. On the other hand, the polishing apparatus of the present invention can be applied not only to the lift type, but also to a mode in which polishing is performed when a slightly inclined pachinko ball is transported as a supply gutter. In addition, the polishing apparatus of the present invention can be installed in an appropriate position at an appropriate position in a pachinko parlor.

[0032]

As described above, according to the present invention, the polishing effect of the pachinko balls is remarkably excellent, and further, the cleaning of the conveyor belt is eliminated or the frequency of the cleaning is significantly reduced, thereby enabling a substantially continuous operation. it can.
