DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for purifying spheres, and more particularly, to an apparatus for polishing small balls such as pachinko balls.

[0002]

2. Description of the Related Art Pachinko balls have been conventionally polished during transportation. A typical device is a so-called lift-type belt polishing device. The lift-type belt polishing device stretches an endless, rectangular cross-section lifting belt between a driving roller disposed at the bottom of the device frame and a driven roller disposed at the top, and raises the lifting belt. On the side, a guide member having a plurality of semicircular spherical passages is provided to face each other, and a lifting belt is run by a motor to pinch and lift the pachinko ball between the lifting belt and the spherical passage of the guide member. A configuration for polishing while feeding is provided. Here, by providing the guide member with a ball passage into which the pachinko ball is fitted, the pachinko ball is reliably held and transported stably. If there is no ball passage into which the pachinko balls are fitted, when the pachinko balls are conveyed while being pressed and sandwiched between the lifting belt and the guide member, the pachinko balls are unevenly distributed and the conveyance may be delayed. In such a lift-type belt polishing device, the pachinko ball adheres dirt to the guide member side in the process of being lifted from the lower entrance side to the upper exit side in the guide member as the lifting belt travels. Transfer and clean. Therefore, between the guide member and the pachinko ball, a cloth or the like as a polishing member for attaching dirt is disposed along the ball passage of the guide member. This cloth or the like absorbs a lot of dirt such as dust, so that it is usually washed every day and used as needed.

[0003] In order to improve the polishing efficiency of pachinko balls, it is desired to increase the contact area between the pachinko balls and cloth as a polishing member. For this purpose, it is conceivable that the cross-sectional shape of the spherical passage is an arc having a large central angle (a deep semicircle). However, if the ball path is formed into a deep semicircle, it is difficult to always arrange the cloth along the plurality of ball paths, and there is a possibility that the conveyance of the pachinko ball may be delayed. As means for avoiding this, it is conceivable to use brushes for the polishing member. However, since it is difficult to form brushes into a semicircular cross section like cloth, it is not practical to arrange them along a plurality of spherical passages. Therefore, when brushes are used as the polishing member, a concave groove is provided on the bottom surface of the guide member, and the brushes protrude from the concave groove into the spherical passage. Such means,
For example, it is disclosed in JP-A-8-289967 "Guide rail member in pachinko ball polishing / lifting machine". According to this configuration, it is possible to polish the pachinko balls with the brushes, but there is a restriction on the length and the installation site of the brushes. For this reason, the flexibility of the brushes cannot be effectively used, and the contact area with the pachinko ball cannot be increased. In addition, since there are a plurality of structures, it is difficult to keep manufacturing costs low.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. Here, the object of polishing and transport is a pachinko ball used in a pachinko game facility, but the present invention can be applied to a general sphere in general. Further, the embodiment can be appropriately changed in design without departing from the gist of the present invention.

FIGS. 1 and 2 are a front view and a side view of a pachinko ball polishing and conveying apparatus according to the present invention. This device is disposed, for example, at the center of the pachinko island, receives discharge spheres (P) from each pachinko table at an inlet (14) at the lower part of the device,
It has a function of supplying again from the exit (15) at the top of the device to the prize ball storage tank of each pachinko machine. The pachinko balls (P) are polished by the cleaning means (C) in the process of being pumped from the inlet (14) to the outlet (15). In the figure, the pachinko ball (P) is shown to be vertically transported vertically, but it is not always necessary to perform the vertical vertical transport. For example,
Depending on the characteristics of the constituent members and the positional relationship with the surrounding devices, it may be more convenient to carry them in an inclined manner or in a curved manner.

The outline of the configuration for transporting the pachinko balls (P) is as follows. In the housing (11), a conveyor belt (20) for conveying a pachinko ball (P) is provided at an entrance (1).
4) From the vicinity to the exit (15). The transport belt (20) is stretched around a driving roller (23) and a driven roller (24), and the driving roller (23) is
It is rotationally driven by a motor (21) via a drive belt (22). Therefore, the pachinko ball (P) that has flowed into the entrance (14) comes into contact with the conveyor belt (20) at the position on the outer peripheral surface of the drive roller (23), and rises as the conveyor belt (20) is driven. At the position on the outer peripheral surface of the driven roller (24), the driven roller (24) separates from the conveyor belt (20) and is discharged from the outlet (15). In addition, on the upstream side of the cleaning means (C), a pachinko ball (P) is provided inside the housing (11) at a position facing the conveyor belt (20).
A pressing member (not shown) may be appropriately provided to press the sheet into contact with the conveyor belt (20) to ensure the conveyance.

By the way, the transport belt (20) has a structure shown in FIG.
As shown in the plan cross-sectional view of FIG. 5, a plurality of gutter grooves (20a) having a linear shape along the belt conveyance direction (m) and having a cross-sectional shape into which a part of the pachinko ball (P) fits are provided. As for the number of gutters (20a), the greater the number, the better the transfer efficiency and the number of gutters in the figure is eight. Therefore, when the pachinko balls (P) are transported while being pressed and clamped between the transport belt (20) and the cleaning means (C), one pachinko ball (P) is placed in each gutter groove (20a). It is inserted. This prevents the pachinko balls (P) from being unevenly distributed in the belt width direction at the time of conveyance and delaying the conveyance, and the pachinko balls (P) are securely held and smoothly and stably conveyed. A feeding member (not shown) is provided between the inlet (14) and the driving roller (23) so that the pachinko balls (P) are supplied steadily one by one to each gutter groove (20a). Have been. The feeding member is provided with a pachinko ball introduction gutter in a shape of a pen, and the groove of the introduction gutter and the gutter groove (20a) of the conveyor belt (20) coincide with each other in the belt width direction. Gutter (20
It contributes to stable supply to a).

As described above, the pachinko balls (P) are transported while being fitted into the plurality of gutter grooves (20a) provided on the transport belt (20).
Polished by The structure of the cleaning means (C) is as follows. First, the cleaning means (C) is preferably installed inside the door (12) of the housing (11) as shown in FIG. The door (12) is installed to be openable and closable via a rotation support member such as a hinge (13) provided on a side portion thereof. This is to contribute to the convenience of cleaning or replacing the cleaning member (30) contaminated by polishing the pachinko ball (P) with a new one.

The pachinko balls (P) fitted into the gutter grooves (20a) of the conveyor belt (20) are transported by the cleaning member (3).
It is polished by contacting 0). As the material of the cleaning member (30), any material can be used as long as it has a function of polishing the pachinko balls (P), such as fibers and synthetic resins. As the shape of the cleaning member (30), a macroscopic flat plate can be suitably used. That is, it has a large area on the surface facing the conveyor belt (20), and has a predetermined length (thickness) toward the conveyor belt (20). Since the cleaning member (30) has a certain thickness, the pachinko ball (P) is buried in the cleaning member (30) as shown in FIG. 3, so that the contact area can be increased. In addition, since the whole is flat, there is an advantage that processing is easy.

Although the cleaning member (30) may be macroscopically flat, it is preferable that the tip portion, that is, the portion facing the pachinko ball (P) has an uneven shape. FIG.
FIG. 4 is a plan sectional view showing a state where the pachinko ball (P) is polished by the cleaning member (30). The tip of the cleaning member (30) in this figure has a conical projection (3).
0a) are provided in large numbers. Due to the presence of the projections (30a), irregularities are formed in a portion of the cleaning member (30) macroscopically flat which faces the pachinko ball (P). That is, the projection (30a) itself corresponds to the projection of the unevenness, and the gap (3) between the projection (30a) and the projection (30a).
0b) corresponds to the concave and convex concave portions. When such irregularities are provided, the projections such as the projections (30a) have a function of scratching and polishing the pachinko spheres (P), and the pachinko spheres (P) are immersed in the recesses which are the voids (30b) to make contact. This has the effect of increasing the area.

The cleaning member (30) may be a flat plate having a large number of cut lines instead of having such irregularities. That is, the tip of the cleaning member (30) does not have a concave portion corresponding to the gap (30b).
It is composed only of a convex portion corresponding to the projection (30a). According to this, the pachinko ball (P) breaks into a cut line that can be a concave portion between the convex portions, thereby expanding the cut line and forming a void as a concave portion. The protrusions (30)
Scratched and polished as in a).

As described above, the cleaning member (30) is a flat plate having a predetermined thickness macroscopically. If the tip has a large number of irregularities or cuts, the pachinko ball (P) may be used. It can be polished effectively. Therefore, it is a collection of many linear bodies densely planted with their longitudinal directions aligned in parallel,
It is also possible to configure a cleaning member (30). In particular, a linear assembly such as a brush having a predetermined length and rigidity can be simply and suitably used. If the linear body has a certain degree of rigidity, it has a high function of scratching and removing dust adhering to the printed portion on the surface of the pachinko sphere (P) and can be effectively polished. In addition, if the bristle feet are long, there is an advantage that the ability to be strongly scratched is enhanced by bending due to rigidity, and that the contact is made over a large area of the pachinko ball (P) surface, so that the polishing can be more effectively performed.

The cleaning member (30) in this embodiment is provided with the following pressing means for pressing the cleaning member (30) in the direction of the gutter groove (20a). The cleaning member (30) is attached to the thin plate-shaped member (31). On the door (12) side of the plate-like member (31), a plurality of small projection-shaped regulating columns (32) are protruded, and an elastic body (33) such as a spring is provided. Due to the restoring force of the elastic body (33), the cleaning member (30) is made to approach in the direction of the gutter groove (20a), but a stopper (3) protruding in a flange shape inside the door (12).
The limit of approach distance is defined by contacting 4). Conversely, when the cleaning member (30) is pressed by a pachinko ball (P) or the like, the cleaning member (30) is
In the direction away from a), the resilient body (33) is used to repel the obstacle flexibly, but the tip of the regulating column (32) is closed by the door (1).
2) The limit of the avoidance distance is defined by contacting the inner surface. As described above, the cleaning member (30) is provided with the gutter (20).
The range (r) to be moved in the direction a) is the stopper (34).
And the length of the regulating column (32).

Here, the cleaning member (30) is provided with a gutter (2).
The position closest to 0a) is set to a position where the tip of the cleaning member (30) reaches the approximate center of the pachinko ball (P) fitted into the gutter groove (20a). Then, while the pachinko ball (P) can be sufficiently held by the gutter groove (20a), approximately half of the surface of the pachinko ball (P) comes into contact with the cleaning member (30), and a certain polishing efficiency can be obtained. . Furthermore, the difference in the coefficient of friction between the cleaning member (30) and the gutter (20a),
Since the pachinko balls (P) often rotate during the transportation due to the discontinuous shape of the cleaning member (30), etc.,
The entire surface of the pachinko ball (P) is efficiently polished.

In order to make the pachinko ball (P) easily rotate, as shown in FIG. 4, the radius of curvature (20r) of the cross section of the gutter groove (20a) is slightly larger than the radius (Pr) of the pachinko ball. It is preferable to make it larger. Then, a gap (20b) is generated between the pachinko ball (P) and the gutter groove (20a), so that the pachinko ball (P) easily rolls and rotates in the gutter groove (20a).

On the other hand, the cleaning member (30) is provided with a gutter (20).
The position farthest from a) is set at a position where the tip of the cleaning member (30) comes into contact with the end face of the pachinko ball (P) fitted into the gutter groove (20a). Then, the pachinko ball (P) is prevented from falling off from the gutter groove (20a), and
Even when the pachinko balls (P) are conveyed overlapping and reach the cleaning means (C), the conveying path is expanded by the cleaning member (30) moving away from the gutter groove (20a), and the pachinko balls (P) are expanded. Is transported stably without stagnation or uneven distribution.
