This invention relates to a lifting and polishing device for pachinko balls, which lifts the balls while polishing them and purifies dirty synthetic resin pellets.

[Prior Art] A pachinko ball lifting and polishing device is known from JP-B-63-28630. The device comprises a lifting tube which has a spiral body inside and which agitates and mixes the pachinko balls and synthetic resin pellets by the rotation of the spiral body, thereby lifting the pachinko balls while polishing them, a sorting section which is provided at the upper opening of the lifting tube and which separates the polished pachinko balls from the synthetic resin pellets, and a regenerator which polishes the separated synthetic resin pellets.

[Problems to be solved by the invention] However, since this conventional recycling machine removes dirt by scraping off the surface layer of the synthetic resin pellets using a cutting machine, fine particles may be left on the surface of the synthetic resin pellets by cutting. There are problems in that scratches occur, and dirt gets into the scratches, making cleaning even more difficult, and the surface is scraped, resulting in heavy wear and tear, making it uneconomical. In addition, conventional regenerators have problems such as their complicated structure and the fact that they are inserted in the middle of the synthetic resin pellet circulation path, making the entire device large.

The present invention was devised in view of the problems of the conventional technology, and its purpose is to remove dirt adhering to the surface of synthetic resin pellets without cutting them. It is an object of the present invention to provide a novel pachinko ball lifting and polishing device that is more economical and can be downsized as a whole.

[Means for Solving the Problems] In order to achieve the above object, the pachinko ball lifting and polishing device of the present invention has a spiral body inside, and the rotation of the spiral body separates pachinko balls and synthetic resin pellets. A lifting cylinder that polishes and lifts pachinko balls by stirring and mixing the balls, has a separating section for separating pachinko balls and synthetic resin pellets at the upper end opening, and the separating section has a mesh member that receives the separated synthetic resin pellets. and a driving source for moving the mesh member.

The mesh member of the cleaning means is formed into a flat plate shape or a cylindrical conical shape with both sides open, and the flat plate type is given linear reciprocating motion or vibrational motion by a driving source, and the cylindrical conical type is Preferably, it is configured to provide rotational motion.

[Operation] The synthetic resin pellets sent to the sorting section from the upper end opening of the transport tube are separated from the pachinko balls and received in the mesh member. Then, as the mesh member is moved by the drive source, it is forcibly transferred while being rubbed against the mesh of the mesh member, and dirt adhering to the surface at that time is removed.

[Examples] Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the entire pachinko ball lifting and polishing device according to the present invention, and FIG. 2 is a longitudinal sectional view thereof. In the figure, 1 is a base, 2 is a lifting cylinder installed perpendicularly on the upper surface of the base 1, and 3 is a lateral feeding cylinder that communicates with the lower end of the lifting cylinder 2. A first helical body 5 connected to the rotating shaft of a motor 4 is inserted into the lifting cylinder 2, and a second helical body 7 connected to the rotating shaft of a motor 6 is inserted into the cross-feeding cylinder 3. has been done. 8 is a supply port for pachinko balls B provided in the horizontal feed tube 3; 9 is an inlet for synthetic resin pellets P serving as an abrasive; and 10 is an upper end opening 11 of the lift tube 2.
The sorting section 10 is installed in the box body 12 and has a screen 13 with a gap smaller than the diameter of the pachinko balls B in the upper part of the box body 12 in a slightly downwardly sloping shape. It is set up and configured.

14 is a cleaning means for removing dirt adhering to the surface of the separated synthetic resin pellets P, and as shown in FIG.
It consists of a mesh member 15 provided at the lower part of the mesh member 15, and a drive source 16 for moving the mesh member 15.
The mesh member 15 is formed into a flat plate by, for example, stretching a nylon mesh 15b having a mesh smaller than that of the synthetic resin pellets P on a rectangular frame 15a. It is movably supported and has one end protruding from the side of the box body 12 to the outside. The drive source 16 is, for example, a motor, and is installed on the outside of the box body 12 in correspondence with the lower part of the protruding end of the mesh member 15. A crank 19 is fixed to the output shaft 18 of the mesh member 15 in order to linearly reciprocate it, and the pin 20 of the crank 19 is configured to slide within a groove 31 formed in the frame 15a of the mesh member 15. be done.

Note that the mesh member 15 is made of synthetic resin pellets P.
Any material can be used as long as dirt can be removed by friction without damaging the surface of the material.For example, it may be a wire mesh or a punched metal plate with many small holes drilled in it and coated with a synthetic resin or the like. . In the figure, reference numeral 21 indicates an inclined guide plate for dropping the separated synthetic resin pellets P onto the end of the mesh member 15, and 22 indicates a mesh plate 23 attached to the bottom of the box body 12, and a lower part of the mesh plate 23. A dust collector 25 has a suction hose 24 facing the dust collector, and 25 represents a circulation cylinder whose upper end is connected to the bottom of the box 12 and whose lower end faces the inlet 9 for the synthetic resin pellets P.

The pachinko ball lifting and polishing device of the present invention having the above-mentioned configuration has a supply port 8 and an inlet port 9 connected to a horizontal feed tube 3.
The pachinko balls B and synthetic resin pellets P supplied inside are stirred and mixed by the first and second spiral bodies 5 and 7 rotated by the motors 4 and 6 while being directed toward the upper end opening 11 of the lifting cylinder 2. and transport it. When the pachinko ball B and the synthetic resin pellet P are stirred and mixed, the dirt on the pachinko ball B is attached to or removed from the surface of the synthetic resin pellet P due to mutual contact friction, and the pachinko ball B is polished. .

The pachinko balls B that have reached the upper end opening 11 of the lifting tube 2 are then transported to the sorting section 1 along with the synthetic resin pellets P.
The synthetic resin pellets P are sent out onto the screen 13 of No. 0 and supplied to each pachinko machine via the supply gutter 26, and are separated from the pachinko balls B and fall from the gap between the screen 13 onto the inclined guide plate 21, where they are further cleaned.
