DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial application] Removes dirt attached to objects.
In particular, the present invention relates to a coin polishing machine with a counter that adds a polishing device to a counter used in a pachinko hall to polish, clean, and remove dust attached to coins, medals, and the like.

[0002]

2. Description of the Related Art The dirt attached to a conventional object is removed.
For example, as a method of polishing and removing dust adhering to coins, medals, pachinko balls and the like used in a pachinko hall, there are a resin pellet particle bath type, a hot water washing type, a pile cloth tape type, and the like. The resin pellet grain bath method is to stir in a resin pellet bath to adhere and transfer dirt on the surface of the coin to the resin pellet. In the hot water washing type, washing is performed directly with hot water using a brush and the like. The pile type tape is disclosed in JP-A-7-625 and JP-A-7-602.
No. 00, a polishing belt urged against the surface of a coin is pressed against the surface of the coin, and the surface of the coin is polished to remove dirt, grease, dust, etc. on the surface of the coin by wiping the belt surface. It is.

[0003]

The above-mentioned resin pellet particle bath method has the following disadvantages. (1) Since the pellets need to be separated and cannot be completely separated, they are clogged with a hopper of a game machine or a medal lending machine. (2) Pellet exchange, washing and drying operations are required. (3) Since the powder of the pellets is transferred to the player in a state where the powder adheres to the material to be polished, the hands of the player become dirty. (4) The device for mixing the material to be polished and the pellets is large and heavy, and is not suitable for installation in a hall.
The hot water washing method has the following disadvantages. (1) The medal changes color. (2) Since hot water is used, installation in the hall is not appropriate. A separate washing area is required. (3) Since dirt accumulates in the hot water, the hot water needs to be replaced frequently. Furthermore, the pile type tape type has the following disadvantages. (1) The contact section between the coin and the tape is short for wiping, and it is difficult to remove dirt when the processing speed is increased. Decreasing the processing speed reduces the number of wipes. (2) The number of parts of the wiping mechanism is large and the apparatus becomes complicated. (3) The pile fabric is a consumable and needs to be replaced when the stain removal performance is reduced. From the above, in order to obtain a device that performs the collection, polishing cleaning, and replenishment of the polished material in each island of the pachinko hall in a fully automatic manner,
Regarding the polishing and cleaning, the conventional techniques as described above cannot cope with the completeness of the removal of dirt, the large amount of work, and the large cost. Therefore, the present invention enables the polishing and cleaning to be completely performed without using abrasives such as pellets, hot water, and detergents, and a cleaning agent, and furthermore, by attaching it to a counter, the number of cleaned polished materials can be counted. It is an object of the present invention to obtain a coin polishing device with a counting machine.

(19) Released above. The dust that has reached the chute (19) having a porous or mesh shape falls downward. The dust is reliably removed by providing a dust collector (21) that sucks through the filter (20) below the chute (19). The quantity of the material to be polished from which the dirt has been removed at the dust collecting portion is further counted by a counter (23) provided at the tip thereof.

[0009] In the above, the dust collector (2
If the filter (20) of 1) is of a detachable pack type, the dirt on the material to be polished can be easily treated by replacing the filter like a home vacuum cleaner. Further, if the fastening screw (15) is removed and the top plate (7) is removed, the rotating brush (10) and the fixed brush (13) can be easily removed. At this time, dirt can also be removed by cleaning the rotating brush (10) and the fixed brush (13) with another brush or the like. The fastening screw (15) may be hinged on one side and fastened on the other side with a lid for quick and easy operation. In order to fix the fixed brush (13) to the upper plate (7) and the rotating brush (10) to the rotating plate (1), if it is not enough to just fit them, screws or the like are used. In any case, it is better to be easy to attach and detach. The rotating plate (1) is supported by a support plate (5) via ball bearings (6) arranged along the circumference, and the ball bearing is a thrust bearing, a needle roller bearing, or a support as shown. The grooves may be provided in the plate (5) and the rotating plate (1) to arrange the balls. The rotating plate (1) is driven by a driving device (motor) (3) to a speed reducer (4).

Further, the central portion may be provided with a projection to prevent bridging at the time of pouring the material to be polished and to promote quick scattering to the outer peripheral portion. Further, the shape of the introduction portion (11) of the top plate (7) is provided with a taper having a high inner circumference and a low outer circumference as shown in FIG. The effect of wiping the material to be polished can also be obtained by replacing the brushes (10) and (13) in the cleaning and polishing portion of the rotating plate (1) and the upper surface plate (7) with buffs and cloth. Further, the clean polishing section can be divided into a brush and a buff on the upper and lower sides on the inner side and a buff on the upper and lower sides on the outside, and these have a replaceable structure. In addition, the example in which the upper plate on which the brush is mounted is fixed has been described, but this may be rotated. In this case, the rotation of the upper and lower brushes is changed. In any case, the material to be polished is moved in the outer peripheral direction by the centrifugal force of the rotating plate,

According to the present invention, since pellets, hot water, detergent and the like are not used, operations such as replacement of pellets, washing and drying, replacement of hot water, and consumables are not required. Further, since pellets are not used, troubles caused by mixing of pellets are prevented. Furthermore, since the supporting plate is supported by the rotating plate via ball bearings arranged along the circumference, and the upper surface plate is fixed to the supporting plate via the coil spring, the gap between the cleaning and polishing members is movable. This makes it possible to adjust the contact pressure to a constant value, so that the gap between the fixed plate and the rotating plate can be kept uniform. Further, since a dust collector for sucking air through a filter is provided below the chute, dirt can be surely removed. In any case, it is possible to obtain a coin polishing machine with a counter in which polishing and cleaning are completely performed only by replacing the filter and cleaning or replacing the cleaning polishing unit.
