DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing apparatus in a pachinko ball conveying process.

[0002]

2. Description of the Related Art Conventionally, pachinko balls are polished during transportation, and a so-called lift-type belt polisher is known as a pachinko ball polisher for performing such polishing. This lift type belt polishing apparatus is disclosed in
As disclosed in JP-A-125365 and JP-A-2-25288, a guide member having a gutter groove through which a pachinko ball passes, and a transport belt for transporting the pachinko ball while pressing the pachinko ball against the gutter groove side are provided. Things.

[0003] In this lift type belt polishing apparatus, the pachinko balls adhere to the endless belt in the course of being lifted from the lower entrance side to the upper exit side in the gutter groove as the endless belt rotates. Is cleaned. The pachinko balls thus discharged are supplied to each pachinko machine. Since a lot of dust and the like adhere to the lifting endless belt used in this lift type belt polishing device,
It is washed at an appropriate time, usually every day.

[0004] On the other hand, in a process in which a screw conveyor is provided in a lifting cylinder and pachinko balls are lifted together with abrasive grains (abrasive beads), dirt attached to the pachinko balls is polished and removed by the abrasive grains. Many proposals have been made, such as 2-34931.

However, in this conventional polishing apparatus,
Dust, hand marks, oil, etc. attached to the pachinko balls,
Basically, transfer to endless belts or abrasive beads.If the belt or abrasive beads become dirty after a long operation, clean the belt or abrasive beads and reuse them or replace them with new ones. Have to be replaced.

Further, in the lifting method using an endless belt, the dirt is transferred to a lifting belt made of cloth, and it is necessary to remove the lifting belt from the polishing apparatus and wash it frequently. For this reason, in pachinko parlors, it is necessary to wash the lifting belt almost every day after the business hours, which is a heavy burden.

In order to solve this problem, the present applicant has filed Japanese Patent Application No. Hei 6-100231 or Japanese Patent Application No. Hei 6-10556.
No. 0 discloses a polishing and conveying apparatus which is excellent in the effect of polishing a pachinko ball, and which eliminates or significantly reduces the frequency of cleaning of a conveying belt and which can be operated substantially continuously.

[0008]

According to the polishing and conveying apparatus proposed by the present applicant, when polishing the pachinko balls in the course of conveying the pachinko balls, dusts and the like of the pachinko balls are removed from between the polishing members. Since it is made to escape to the back side, dirt does not adhere to the transport belt. In addition, since the polishing beads are not used, there is no danger that polishing beads may be mixed into the pachinko machine through the pachinko ball supply system by mistake, and there is an advantage that troubles can be prevented.

[0009] However, in course of a long time driving, if the transport of the pachinko ball is no longer smooth by external force unexpectedly abrasive member in the Haujin grayed, polishing member groups is biased to the downstream side or upstream side integrated The phenomenon of doing it was seen.

[0010] This cause could not be elucidated at first, but as shown in FIG. 16, which is in contrast to FIG. 12, which will be described later, the polishing members 2A, 2B. As shown in the figure, it is found that the polishing members 2A, 2B,... Are aligned in an inclined state by connecting the shortest portions of the polishing members in the conveying direction by not being perpendicular to the conveying direction.

Therefore, an object of the present invention is to align polishing members in a regular state and to provide a polishing function that is stable for a long period of time.

[0012]

[0020]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. FIGS. 1 and 2 show an overall view of a lift-type polishing apparatus according to the present invention, which is provided, for example, at the center of an island of a pachinko machine. An endless cloth-made transport belt 4 is disposed opposite to the guide path constituted by the polishing members 2, 2,.... Downstream of the guide polishing members 2, 2,... In the housing 1, a pachinko ball cleaning means 3, which is not described in detail, is provided. The transport belt 4 is wound around upper and lower drums 5 and 6, and an output shaft of a drive motor 7 is driven by a lower drum 6 rotated via a drive belt 8.

The dirty pachinko ball B0 is introduced into the alignment inlet 9, and is guided between the guide polishing member 2 and the transport belt 4 whose structure will be described later, and the crimping of the pachinko ball by the relative resilient pressure. In the process, the dirt is mainly scraped off and polished at the downstream edge of the guide polishing member 2, and is also lifted upward by the conveying force of the conveying belt 4. Thereafter, the conveyed material that has been conveyed between the cleaning means 3 and the conveyor belt 4 disposed on the downstream side and has not been completely removed at the time of polishing and has adhered to the pachinko balls B1 is pressed against the cleaning means 3 of the conveyor belt 4. It is wiped off by contact with the cleaning means by pressure.

The polishing ball B2 thus polished and from which the deposits have been removed is discharged from the outlet 10. Reference numeral 1A denotes a main structural member. The detachable metal fitting 1B is detached, the housing 1 is detached, and the inside of the housing 1 is disassembled or easily cleaned when necessary.
When the housing 1 is removed, the conveyor belt 4 is exposed.

The guide polishing member 2 and its holding structure will be described with reference to FIGS.

That is, as shown in FIG. 3, the substantially U-shaped structural main material 1A and the substantially U-shaped housing 1 are arranged to face each other, and a gap is provided in the height direction within the structural main material 1A. Are arranged, and the conveyor belt 4 wound between the upper and lower drums 5, 6 is guided along the way by a group of guide rollers 11, 11,.

As can be seen from FIG. 3, one side of the conveyor belt 4 passes inside the main structural member 1A, while the other side passes outside the main structural member 1A. The guide roller 11 is provided between both side plates of the main structural member 1A via bearings 12 at both ends thereof,
It is designed to rotate freely.

Guide polishing member 2 in housing 1
Are provided, for example, in units of 10 with respect to the movement restricting bodies 13 provided in a large number in the height direction. Polishing member 2
Has a rather complex shape. That is,
Have a foot portion 21 on both sides and the center of the main body, and gutter grooves 22, 22,... Along a semi-cylindrical conveyance direction (height direction) are spaced from each other in a direction (width direction) orthogonal to the conveyance direction. For example, eight are formed.

Further, the upper portion of the polishing member 2 is inclined as a whole downstream (in the height direction) in the transport direction, and the inclination angle of the upstream inclined surface 23 is slightly larger than the inclination angle of the downstream inclined surface 24. large. Further, the gutter grooves 2 except for the gutter grooves 22 at both ends are provided on the upstream-side standing surface 25 at intervals in the width direction.
The slits 26 for passage corresponding to the center positions of 2, 22,.
26 are formed. The downstream standing surface 27 is a flat surface. An elastic spring 28 is interposed in the concave hole 21A opened below the feet 21, 21, 21 and is arranged with the movement restricting body 13 as a seat.

As shown in FIG. 4, the movement restricting body 13 has a structure in which guide walls 13B are erected along both sides of the main body plate 13A in the transport direction. Guide wall 13B, 1
The spacing between the guide walls 13B, 13B is set between 3B so that both ends of the polishing member 2 are fitted so as to have some play. Further, small recesses 13C, 13C,... For preventing displacement of the resilient spring 28 are formed at positions corresponding to the recesses 21A.

Thus, one set of the movement restricting body 13 and the ten polishing members 2, 2... Provided on the movement restricting body 13 via the spring 28 (hereinafter, also referred to as a unit polishing block set) is shown in FIG. As shown in FIG. For example, a set of unit polishing blocks having a length of 15 cm is disposed in the housing 1 so as to be adjacent to the set in the transport direction by about 10 to 18 sets.

On the other hand, as shown in FIG. 2, the dirty pachinko balls B0 are thrown in through the alignment inlet 9, and while being aligned here, as shown in FIG. It enters the gutter groove 22 of the polishing member 2 and is pushed upward while being pressed against the conveyor belt 4. in this case,
The polishing member 2 is resiliently pressed toward the transport belt 4 from behind by a resilient spring 28.
6 and the guide rollers 11, 11,..., The pachinko balls B0 are pressed by the conveyor belt 4 toward the gutter grooves 22 of the polishing member 2. At this time, due to the movement of the conveyor belt 4, each pachinko ball B0 is conveyed while rolling.

The principle of polishing in the rolling and conveying process of the pachinko ball B0 will be described in more detail. That is, as shown in FIG. 14, when the pachinko ball B0 is in the first polishing member 2A, the tension of the transport belt 4 is large and a substantially flat surface is maintained. First
The polishing member 2A is pressed down (moved down in the drawing) toward the movement restricting body 13 and the housing 1 against the urging force of the spring 28, and the pachinko ball B is pressed down.
Roll 0.

As shown in FIG. 15, the pachinko balls B0 are rolled and conveyed by the pachinko balls B0 to the first polishing member 2A.
In the process of moving from the first polishing member 2B to the next polishing member 2B, the surface of the pachinko ball B0 comes into contact with the terminal edge of the gutter groove 22 of the first polishing member 2A, that is, the intersection edge between the downstream inclined surface 24 and the gutter groove 22. . Further, as the rolling of the pachinko balls B0 progresses, the pressing force of the first polishing member 2A by the conveyor belt 4 is released, and the first polishing member 2A is restored to the position on the conveyor belt 4 side.
Instead, the second polishing member 2B is pushed down. As a result, while the step between the initial part of the end edge of Toimizo 22 of the first polishing member 2A and the second polishing member 2B gradually increases (the process of the state of FIG. 15 from the state of FIG. 14), the The transfer to the second polishing member 2B is performed. During this transfer process, the contact of the terminal edge with the pachinko ball B0 surface is maintained, and the pachinko ball B0 is scraped off by the terminal edge because the pachinko ball B0 rolls. As a result, pachinko balls B0
Dirt adhering to the surface is scraped off by the terminal edge.

The scraped-off dirt mainly falls along the downstream inclined surface 24 to the movement regulating body 13 side or is pushed out sequentially. At this time, the downstream inclined surface 24
Although the downstream-side standing surface 27 and the upstream-side standing surface 25 that are continuous with each other are in close contact with each other, since the passage slits 26 are formed corresponding to the center positions of the gutter grooves 22, 22,. Can flow out to the back side of the polishing member 2 without being deposited on the contact surface.

Here, as shown in FIG. 3, the ascending limit of each of the polishing members 2 is defined by both shoulders and corresponding housings.
And the lip portion 1a of the grayed 1 is defined by abutment. Thus, the polishing of each pachinko ball B0 is continuously performed.

The polished pachinko balls B1 are transported by the conveyor belt 4 to the position of the cleaning means 3 described above.

As the conveyor belt 4, the gutter grooves 22, 22
.., Instead of a common transport belt, a transport belt corresponding to each gutter groove 22, 22,. Further, the shape of the gutter groove 22 can be a shape other than an arc as long as the pachinko balls roll smoothly.

In the above example, a group of guide walls 13 B is formed on the movement restricting body 13. The reason why the movement restricting body 13 is interposed in the housing 1 is to simplify the manufacturing and maintenance by assembling the polishing members 2, 2... In units of the movement restricting body 13. Alternatively, a guide wall may be formed directly on the housing 1. In this case, the resilient spring 28 is directly provided with the housing 1 as a seat. Note that even when the movement restricting body 13 is provided, when a through hole is formed instead of the concave hole 13C,
The resilient spring 28 directly seats the housing 1.

The guide wall 13B can be formed at an appropriate location in addition to the both ends in the transport direction as shown in the illustrated example. Also, the shape is not limited as long as the positions of the polishing members 2, 2,...
