DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing apparatus for polishing pachinko balls using an abrasive (hereinafter simply referred to as "polishing apparatus").
It is about.

[0002]

2. Description of the Related Art Abrasive materials used in a polishing apparatus are poly,
Also called pellets, abrasive grains, etc., for example, a synthetic resin called “nylon 6” according to JIS (Japanese Industrial Standards) is
It is generally formed in a cylindrical shape having an outer dimension of about 1 to 2 mm, a length of about 2 to 3 mm, and a weight of 0.5 g or less. The pachinko ball is polished by mixing and agitating such a synthetic resin abrasive in a metal pachinko ball. The dust that has adhered to the pachinko balls adheres to the abrasive by this polishing (in this specification, the abrasive to which dust adheres is referred to as “abrasive with dust”). The abrasive with dust is separated from the polished pachinko balls, and the dust is further separated into a separated abrasive (in this specification, the abrasive from which dust is separated is referred to as a "separated abrasive"). The sorted abrasive is re-input to the polishing means forming a part of the pachinko ball polishing apparatus via the abrasive path (for example, see Japanese Patent Application Laid-Open No. 11-207006).

[0003]

There are various types of the above-mentioned abrasive material paths depending on the structure of the pachinko ball polishing apparatus in which the abrasive material paths are used, and some of them are necessary or inevitable. Some have a structure in which a certain amount of abrasive is deposited (stored). An abrasive window having such a structure is often provided with a viewing window that can be visually recognized by a viewer to monitor the state of deposition. On the other hand, the pachinko ball polishing device is generally installed in an area called an island in which a plurality of pachinko machines are assembled, but since this island is surrounded by the pachinko machines, light of external illumination is not provided. It is hard to reach inside. For this reason, in order to visually recognize the abrasive in the abrasive material path while having the above-mentioned visible window, it was necessary to illuminate the inside of the circulating furnace through the visible window with a flashlight or the like. Of course, the island has only a small and limited space, so visual work while holding a flashlight etc.
In fact, it is extremely inefficient and places an excessive burden on viewers and the like. The present invention has been made to improve the above-described situation, and has an object to reduce a burden on a viewer or the like who wants to visually recognize an abrasive in an abrasive passage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention (hereinafter, referred to as "the present embodiment") will be described with reference to the drawings. FIG. 1 is a schematic front view of the polishing apparatus according to the present embodiment, and FIG. 2 is a left side view of the polishing apparatus shown in FIG. 3 is a partially enlarged view of FIG. 2, and FIG. 4 is a partially enlarged view of FIG.

(Overall Structure of Polishing Apparatus) Based on FIG.
The overall structure of the polishing apparatus 1 will be described. Symbol 10 is
Reference numeral 20 denotes a vertically extending lifting pipe, and reference numeral 20 denotes a transfer pipe for transferring an abrasive to the pachinko balls collected from a pachinko gaming machine group (not shown) while mixing the abrasive. . Since the transfer pipe 20 and the discharge pipe 10 in the present embodiment are relatively inexpensive and easy to process, both are made of vinyl chloride. The lower end of the lifting pipe 10 is connected to one end of the transfer pipe 20, whereby both are formed in an L-shape. The transfer pipe 20 and the lifting pipe 10 constitute the polishing means of the present embodiment. are doing.
A horizontal spiral body (not shown) having a transfer motor 22 connected to one end thereof in the transfer pipe 20, and a lifting spiral body (not shown) having a lifting motor 12 connected to the upper end thereof is provided in the lifting pipe 10. , Are provided so as to be freely rotatable.

The polished pachinko balls discharged from the upper end of the lifting pipe 10 and the abrasive with dust are separated by a separating means 30. The polished pachinko balls separated in this way are again transferred to a pachinko machine, a ball rental machine, or the like, and the abrasive with dust is separated therefrom. The separated abrasive that has been separated from the dust and can be reused is re-introduced into a transfer pipe 20 that constitutes a part of the polishing means via an abrasive path described below.

(Structure of Abrasive Material Path) In other words, the abrasive material path in the present embodiment is all of the paths until the separated abrasive material separated by the separating means 30 is re-input to the polishing means (the transfer pipe 20). Specifically, as shown in FIG. 2, a return pipe 32 hanging down from the separation means 30, a bypass pipe 42 branched laterally from the return pipe 32, and a bypass pipe 42
A removable plastic tank 52 configured to receive an abrasive from the AA corresponds to this abrasive path. Hereinafter, the configuration of each member will be described in detail.

(Structure of the return pipe) As shown in FIGS. 2 and 3, the return pipe 32 has an inclined plate 33 (see FIG. 2) therein. It has a function of distributing the material K to the return pipe 32 and the bypass pipe 42. Return pipe 32
Is designed to feed the sorted abrasive K into the transfer pipe 20 through an opening 34 opened at the lower end thereof. K is deposited as shown in FIG. The reason for depositing the sorted abrasive K in this manner is to prevent a shortage of the charged abrasive K by giving a margin to the amount of the sorted abrasive K to be charged into the transfer pipe 20. If the deposited amount of the sorted abrasive K is too small, a sufficient amount cannot be put into the pachinko balls to be polished, and the polishing efficiency may be reduced.
The first viewing window 35 for monitoring this is the return pipe 32
It is provided below. The first viewing window 35 is provided with a transparent acrylic plate, and is configured so that a viewer or the like can visually recognize the accumulation state of the sorted abrasive K in the return pipe 32 from the outside as understood from FIGS. I have. That is, the first viewing window 35 is provided at a position corresponding to an appropriate deposition amount of the sorted abrasive K. If the abrasive is visible from there, the deposition is properly performed. Is provided at a position where it can be confirmed that the amount is too small.

Through holes 37, 37, 37 are formed through the side wall of the return pipe 32 facing the first viewing window 35, and are fixed to the electric board 36 so as to reach from the through holes 37, 37, 37. LED (Light Emitting Diode) 38
a, 38b, 38c. These LEDs 3
8a, 38b and 38c are for irradiating light into the return pipe 32, which is the abrasive material path, to assist the visual recognition of the deposited amount of the sorted abrasive material K. LEDs 38a, 38b,
38c is supplied with current from the power supply unit 39 via the electric board 36. In the present embodiment, there are three, but at least one, and four or more. The power supply unit 39 may be used as a dedicated power supply for lighting the LEDs 38a, 38b, and 38c, but may use a power supply for supplying a current to a pachinko machine or the like. If another power source is used, the LED cannot be turned on when the power source is off, but this is not the case with a dedicated power source. As the dedicated power source, for example, a battery can be used. Note that the LED is suitable in that it can be driven by a battery and consumes a small amount of heat because it consumes very little current, but it assists visual recognition of the sorted abrasive K by irradiating light in the abrasive passage. It goes without saying that a light-emitting body other than the LED can be used as long as it can be used.

As described in the section of the prior art, the separated abrasive K is generally made of a synthetic resin, and is often colored, for example, white, red, blue or the like. . When an LED is used, a color that matches the color of such an abrasive, for example, if the abrasive is red, the emission color is L
When the ED is used, the color interference between the two is small, so that the efficiency of the visual assistance can be further improved. In addition, for example, all of the LEDs 38a, 38b, and 38c shown in FIG. 3 can have the same emission color. However, the LEDs 38a, 38b, and 38c are different from each other, such as colorless, red, and blue, so that the visible light is emitted from any LED. You may comprise so that a viewer can distinguish easily what is an object. With such a configuration, for example, when the colorless one of the visible light is the strongest (when only the colorless light is visible), the LEDs 38b and 38c are blocked by the sorted abrasive K, and only the LED 38a is blocked. If not, the viewer can easily visually recognize that the uppermost portion of the deposited sorted abrasive K is between the LED 38a and the LED 38b.

(Configuration of Bypass Pipe) Referring to FIG. 2, the configuration of the bypass pipe 42 constituting a part of the abrasive material path in the present embodiment will be described. The bypass pipe 42 is a pipe for branching from the return pipe 32 and supplying the sorted abrasive K to the poly tank 52 described later, as described above. When the poly tank 52 is full, the separated abrasive K is deposited and the upper end thereof rises, so that a second viewing window 45 for visually checking the deposited amount is provided in the middle of the bypass pipe 42. The bypass pipe 42 has LEDs 47a and 47 for assisting the work when a viewer or the like visually recognizes it through the second viewing window 45.
b, 47c are provided. These LEDs 47a,
The reason why the power supply units 47b and 47c are provided and the configuration of a power supply unit (not shown) for lighting them are described in the aforementioned L.
Since the reasons and the configuration of the EDs 38a, 38b, 38c are the same, the description thereof is omitted to avoid duplication.

(Structure of Poly Tank) The structure of the poly tank 52 constituting a part of the abrasive material path in the present embodiment will be described with reference to FIGS. The plastic tank 52 is mainly used when exchanging a used abrasive with a new abrasive, and is used after the used abrasive is removed from the abrasive path in a state of containing the used abrasive. Is replaced with a new abrasive, and then is attached to the abrasive path again. The detailed configuration of the plastic tank 52 is disclosed, for example, in Japanese Patent Application Laid-Open No. H11-28288. On the front side wall 52f of the plastic tank 52, there is provided a third viewing window 55 for viewing the stored sorted abrasive K, and LEDs 58a, 58b, 58 for assisting the viewing.
c is provided on the rear side wall 52b (see FIG. 2) facing the front side wall 52f. These LEDs 58a, 5
8b and 58c are provided because the LED 38 described above is used.
For the same reason that a, 38b, and 38c are provided, description thereof will be omitted to avoid duplication. Since the poly tank 52 is configured to be detachable with respect to the abrasive material path, an LED 58 is provided so that the attachment and detachment can be performed smoothly.
The power supply for turning on a, 58b and 58c is constituted by a battery B attached to the poly tank 52.

In the present embodiment, there are three locations: a first viewing window 35 provided in the return pipe 32, a second viewing window 45 provided in the bypass pipe 42, and a third viewing window provided in the poly tank 52. Are provided with a group of LEDs for visual assistance, respectively, a visual window and an LED may be provided in the middle of the abrasive material path other than these, or a portion provided with the visual window visually recognizes the abrasive. If it is not necessary to provide an LED for the reason that sufficient brightness can be obtained from another light source, the LED at that location may be omitted.

(Effects of the present embodiment) According to the present embodiment, when viewing the sorted abrasive K from the first viewing window 35 provided in the return pipe 32, the LEDs 38a, 38
Since b and 38c irradiate light to assist the work, it is possible to easily confirm whether or not the sorted abrasive K put into the transfer pipe 20 is sufficiently deposited in the return pipe 32. Further, when viewing through the second viewing window 45 provided in the bypass pipe 42, the LED 47 is used.
a, 47b and 47c assist the visual recognition work,
When a person is killed via the third viewing window 55 provided in the LED 2, the LEDs 58a, 58b, 58c also assist the viewing operation. Therefore, a viewer or the like does not need to use a flashlight or the like when performing these viewing operations, and thus the labor is reduced.

[0020]

By using the polishing means according to each of the claims, the labor of a viewer or the like is reduced when the abrasive in the abrasive passage is visually recognized.
