Description

[Detailed description of the invention] This invention is equipped with a humidifier that supplies solvents such as water and detergent from an external solvent tank to the polishing body inside the rotating drum, and a blower for drying the polished pachinko balls. This invention relates to a rotating drum type pachinko ball polishing device.

Generally speaking, pachinko balls are polished using a rotating drum-type pachinko ball polishing device that involves a polishing body placed inside the drum and pachinko balls moving inside the drum.In order to efficiently remove the oil on the surface of the balls, The ball is divided into multiple polishing chambers arranged in the axial direction using partition plates equipped with a feeding mechanism, and the wet polishing body placed in the first stage polishing chamber moderately wets the sphere and lifts out the oil on the surface. After that, the balls are wiped and polished with a dry polishing body in the next polishing chamber.

Therefore, it is necessary to keep the polishing body in the first stage polishing chamber appropriately moist.

However, these wet abrasive bodies dry in about a day, so traditionally, employees had to replace the dry abrasive bodies with new wet abrasive bodies before starting work each day, which became an extremely tedious task. .

In addition, the duct of the blower used to dry the polished balls was placed opposite the gutter outside the ball polishing equipment, which caused the air to be scattered around, making it impossible to dry the balls efficiently.

The present invention was devised to solve the above problems, and its purpose is to automatically apply appropriate moisture to the polishing body of the rotating drum and to effectively dry the balls after polishing.

Hereinafter, an example of the present invention will be described based on the drawings.

Reference numeral 1 denotes a rotating drum-type pachinko ball polishing device disposed below an island stand on which a group of pachinko machines are connected. are divided into a plurality of polishing chambers 5a, 5b... each polishing chamber 5a, 5.
A polishing body 6 for polishing balls is placed in b.

The rotating drum 2 is rotatably installed with a front support shaft 7a and a rear support shaft 7b, which are projected outwardly from a front plate 10a and a rear plate 10b, supported by a front support plate 8a and a rear support plate 8b. .

Short cylindrical bodies 9a and 9b with open ends are integrally fixed to the front and rear of the drum 2, and the ends of each are attached to opposing support plates 8a and 8b to the extent that they allow the balls to roll. A ball lead-out chamber 11 is formed in front of the rotating drum 2 with a slight gap therebetween and surrounded by the front support plate 8a, the front short cylinder 9a, and the drum front plate 10a.
A ball lead-out chamber 12 is formed behind the drum and is surrounded by a rear support plate 8b, a rear short cylinder 9a, and a drum rear plate 10b.

Gear 1 fixed to rear support shaft 7b of rotating drum 2
3 is connected to the motor 1 via the belt 14 and reducer 15'.
5.

In this way, the balls 17 introduced into the drum 2 from the collection gutter 16 by the rotation of the drum enter the polishing chambers 5a, 5b.
After being intertwined with the polishing body 6 and polished, it is discharged from the outlet 8b' of the rear support plate 8b, and the lift 18
It will be transported by

In this kind of rotating drum type pachinko ball polishing device, the present invention is such that the front rotation support shaft 7a of the drum 2, which is supported by the front support plate 8a, is formed into a hollow body that communicates with the polishing chamber 5a and the outside. A humidifying device 19 equipped with a solvent tank 19a is installed outside the device 1, and a solenoid valve 19c is provided in a solvent discharge pipe 19b of this humidifying device 19.
9d is passed through the hollow interior of the rotating support shaft 7a, and the tip of the nozzle 19d is inserted into the polishing chamber 5a of the rotating drum 2.
I have made it to you.

In the illustrated embodiment, a solvent tank 19a, a discharge pipe 19
b, a humidifying device 19 consisting of a solenoid valve 19c and a nozzle 19d is attached to a bracket 20 integrally fixed to the outside of the front support plate 8a of the rotary drum 2.

The solenoid valve 19c of the humidifier 19 is electrically connected to the control device 21, and the control device 21 opens the solenoid valve 19c at a desired time and for a desired time to supply the solvent to the first stage polishing chamber 5a. The polishing body 6 in the polishing chamber is appropriately moistened.

This control device 21 may be installed on the base 22 of the polishing apparatus 1 as shown in the figure, or it may be installed in a central control room (not shown) of the hall so that it can be remotely controlled.

Further, an opening 23 is formed in the rear support plate 8b that supports the rear rotation shaft 7b of the rotating drum 2 and constitutes the outer plate of the ball lead-out chamber 12 of the drum 2. The duct 25 of the blower 24 installed outside is shown.

As described above, the present invention can automatically moisten the polishing body in the first stage polishing chamber while the rotating drum is operating, so there is no need to manually replace the dry polishing body as in the past, and the work is significantly simplified. Reduced.

In particular, by adjusting the humidification point and time by operating a solenoid valve, an appropriate amount of moisture can be automatically applied to the polishing body, which has the effect of improving not only work efficiency but also polishing efficiency.

Furthermore, the polished pachinko balls are sent to the ball discharge chamber behind the drum, where they are exposed to the air from the blower, so that the air comes into contact with the balls without waste in the chamber, ensuring efficient drying.
