This invention relates to an automatic ejection type ultrasonic cleaning machine for pachinko balls that is automatically ejected after cleaning.

<Prior Art> In conventional pachinko parlors, only the balls are polished without using a washing machine. As is well known, conventional methods for polishing beads include a belt or drum rotation method using an abrasive cloth, leather, etc., a drum method using an abrasive material, etc., and a method using a screw.

<Problems to be solved by the invention> In the conventional polishing method as described above, the brushes, cloths, sponges, etc. often get dirty, so these must be constantly cleaned or replaced, and maintenance and inspection must be performed constantly. Not,
It requires a lot of manpower to operate, and there are many problems with the equipment. Also, since the balls were not cleaned with a polishing cloth, there was a hygiene problem.

<Means for Solving the Problems> This invention has been made to solve the above problems, and includes an inlet on one end of the main body, an ejection port on the other end,
The input port side of the main body is used as a cleaning tank, the discharge section side is used as a drying section, and in the middle part of the cleaning layer, a screen consisting of a large number of longitudinal bars arranged in parallel at predetermined intervals is installed from the input port side. It is installed so that it slopes downward toward the drying section, so that pachinko balls thrown into the screen from the inlet will roll toward the drying section due to the downward slope of the screen. A drum that rotates around a horizontal axis is arranged, and the screen is curved in an arc from the bottom of the drum toward the discharge port, and the screen is formed by a large number of horizontal protrusions stretched at appropriate intervals on the outside of the drum. In addition to scooping up the upper pachinko balls and dropping them onto the next drying section, the screen and drum in the next drying section have the same structure as the screen and drum in the cleaning tank, and drying air is installed above the drying section. A blowing nozzle is provided to dry the pachinko balls on the screen, and a drum is used to scrape out the pachinko balls after drying to a discharge section, and an ultrasonic vibrator and a bubble generator are installed in the cleaning tank. It is something that

<Function> This invention has the above structure, and when a large number of pachinko balls are thrown into the inlet on one end of the cleaning tank, the pachinko balls are
It rolls along the downward slope of the screen. This screen is made up of a large number of bars arranged in parallel at predetermined intervals in the longitudinal direction, and in the cleaning liquid in the cleaning tank, countless air bubbles are generated in the cleaning liquid by a bubble generator. At the same time, since ultrasonic vibrations are applied by an ultrasonic vibrator, the ultrasonic vibrations are evenly distributed throughout the cleaning tank, effectively removing dirt on pachinko balls, oil valves, iron chains, etc. It can be removed quickly, and at the same time, it is polished by the contact and friction between the pachinko balls.

Also, when it rolls on the screen in the cleaning tank and reaches the drum, it is scraped up by a number of horizontal protrusions placed at appropriate intervals on the outside of the rotating drum and sent onto the screen in the next drying section. . In this drying section, the pachinko balls rolling on the screen are dried by dry air blown out from the nozzle and are discharged from the discharge section.

<Example> Figures 1 and 2 show an example of the present invention, where A is a box-shaped washing machine body, 2 is an input port, 3 is a discharge section, and 1 is the side of the input port 2 inside. 4 is a drying section. Reference numeral 5 denotes a screen provided in the cleaning tank 1, which slopes downward toward the drying section 4.

This screen 5 is made up of a large number of longitudinal bars 6 arranged in parallel at predetermined intervals, and the intervals between the bars 6 are set to a size that prevents pachinko balls from falling.

Reference numeral 7 denotes horizontal shafts supported by bearings provided on both sides of the upper part of the cleaning tank 1 near the drying part 4 and the upper part of the drying part 4 near the discharge part 2, and a drum 8 is fixed to each of these horizontal shafts 7. I'm doing it.

A large number of horizontal protrusions 9 are fixed at regular intervals on the outer periphery of the drum 8. The screen 5 is connected to the cleaning tank 1.
It curves in an arc shape along the drum 8 on the drying section 4 side from the lower part of the upper drum 8 and continues to the protruding section 10 . A next screen 5' is provided in the drying section 4 following this protrusion 10, and this screen 5' has exactly the same shape as the screen 5 in the cleaning tank 1 described above. This screen 5'
The upper part of the protruding part 10' slopes downward and continues to the discharge part 3.

12 in FIG. 2 is a bubble generator installed at the bottom of the cleaning tank 1;
14 is an ultrasonic transducer immersed in the cleaning liquid in the cleaning tank 1, and 15 is an ultrasonic generator for driving the ultrasonic transducer 12. Further, an air nozzle 16 for blowing out dry air is provided on the drying section 4, and a geared motor 17 is fixed to the main body 1, and the shaft of this motor 17 and the shaft of each drum 8 are connected to a changer. Transmission mechanism using a belt 18.
By interlocking each other at 19, each drum 8 is driven in the direction of the arrow in FIG.

Although not shown in the drawings, a liquid circulation filter in which silver activated carbon is packaged is connected to the cleaning tank 1, so that the cleaning liquid in the cleaning tank 1 is circulated through the liquid circulation filter.

In the above embodiment, when the out balls and safe balls discharged from the respective pachinko machines installed in parallel on the pachinko island stand are thrown into the screen 5 in the cleaning tank 1 from the inlet 2, the pachinko balls are It is immersed in the cleaning solution and moved. During this time, the pachinko balls are cleaned by ultrasonic vibrations emitted from the ultrasonic vibrator 14 and diffusely reflected by the bubbles, and polished while rolling on the screen 5.

Then, it is lifted up by the horizontal ridges 9 of the drum 8, climbs over the protrusion 10, and falls into the next drying section 4. The pachinko balls that have fallen into the drying section 4 roll on the screen 5' of the drying section 4, are dried by the dry air blown out from the nozzle 16, are swept up by the horizontal protrusions 9 of the drum 8, and are rolled over the protrusion 10'. It is discharged from the discharge section 3.

Furthermore, if the cleaning liquid is passed through a liquid circulation filter and treated with silver activated carbon, pachinko balls can be sterilized, sterilized, or otherwise disinfected.

<Effects> By continuously supplying pachinko balls to the input port as described above, the pachinko balls that have fallen onto the screen are washed in the cleaning liquid while rolling and moving on the downwardly sloped screen. At the same time, the pachinko balls are polished by contact and friction between them.

During the above-mentioned cleaning, a bubble generator generates countless bubbles that are mixed into the liquid, and each bubble is exposed to ultrasonic waves generated by an ultrasonic vibrator. It is possible to prevent a decrease in cleaning ability due to a decrease in the amount of dissolved air.

In addition, the air bubbles mixed in the cleaning liquid promote the diffused reflection effect of the ultrasonic waves, so the ultrasonic waves are evenly distributed throughout the entire cleaning tank, so the ultrasonic effect is spread over the entire surface of each pachinko ball, and the pachinko ball is Dirt from oil valves, iron chains, etc. adhering to the ball can be removed very effectively.

Moreover, in this invention, there is a drying section next to the cleaning tank, and the drying air is blown from the air nozzle on the screen of this drying section, and the pachinko balls are quickly dried and discharged from the outlet, thereby cleaning the pachinko balls. Both polishing and polishing can be done extremely efficiently. Furthermore, the cleaning liquid can be passed through a liquid circulation filter and treated with silver activated carbon, making it possible to sterilize and sterilize pachinko balls, making this an excellent invention with unprecedented effects from a health and hygiene perspective. I'll go.
