Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves supplying ball polishing pellets made of synthetic resin or the like into a ball polishing cylinder together with pachinko balls, and rotating a spiral body inserted into the ball polishing cylinder. The pachinko balls are cleaned after being transported by the machine, and the pachinko balls and ball polishing pellets are separated by a sorting device, and the selected ball polishing pellets are returned to the ball polishing cylinder for circulation. It is related to the device.

[Prior art] Conventionally, this type of bead polishing device was developed, for example, in 1973-
It is known from Japanese Patent Publication No. 15704, Japanese Patent Publication No. 15151/1983, etc. By the way, in this conventional ball polishing device, the ball polishing pellets separated from the pachinko balls by the sorting device are simply returned to the ball polishing tube via the recovery path and circulated. However, there is a problem in that the dirt and dust removed from the surface of the pachinko balls gets mixed into the ball polishing pellets and is fed into the ball polishing tube again, significantly reducing the cleaning effect of the pachinko balls. Ta.

On the other hand, as a polishing device for game balls that solves these problems, an abrasive recycling device is installed on the transport path that returns the abrasive to the abrasive intake port, and the dust and dirt adhering to the surface layer of the abrasive are scraped off. At the same time, a device in which the shavings are collected in a collector has been proposed (see, for example, Japanese Patent Laid-Open No. 80276/1983).

[Problems to be Solved by the Invention] By the way, in the case of an abrasive recycling device as described above, the entire device is large-scale, and the surface layer of the abrasive is scraped off even if the abrasive is not contaminated. Because of this, the abrasive material is consumed rapidly and is extremely uneconomical.

In addition, in conventional ball polishing devices, the spiral body that lifts pachinko balls and ball polishing pellets while stirring and mixing them is simply formed by twisting a wire rod into a spiral shape, so the lifting force and stirring cleaning ability are limited. There was a problem that both of them were low.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a bead polishing device that has a simple structure, can completely separate and recover dirt, dust, etc. from bead polishing pellets, and can provide a high lifting and cleaning effect.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a pachinko ball and ball polishing pellets that are stirred and mixed and pumped by the rotation of a spiral body inserted therein; A ball polishing device comprising a sorting device that separates pachinko balls and ball polishing pellets sent out from the discharge port at the top of the ball polishing tube, and a recovery passageway that returns the separated ball polishing pellets to the ball polishing tube. In the device, the spiral body has an inner spring wrapped around the outer periphery of the shaft, and an outer spring having an inner diameter such that a gap larger than the diameter of a pachinko ball is formed between the inner spring and the inner spring. are arranged in concentric circles, and mesh plates are arranged opposite to each other in an alternating manner in an inclined manner inside the collection passage, and the dirt adhering to the ball polishing pellets falls downward from the mesh plates to form a dust collection device. It is designed to be collected by suction.

[Operation] The pachinko balls and ball polishing pellets fed into the ball polishing tube are stirred and mixed by the rotation of the spiral body and are pumped up and sent from the discharge port to the sorting device. When the pachinko balls and ball polishing pellets come into contact with the inner ring spring of the spiral body, they receive a strong lifting force, and when they come into contact with the outer ring spring, they also receive a strong stirring and cleaning force.

On the other hand, the pellets for polishing balls sent out from the outlet of the polishing tube are separated from the pachinko balls by a sorting device, and are returned to the polishing tube while falling onto the mesh plate of the recovery passage. Dirt, dust, etc. mixed in the polishing pellets fall through the mesh while moving on the mesh plate and are sucked and collected by the dust collector.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In the figure, 1 is a base, 2 is a cylindrical beading tube installed vertically on the base 1, and a spiral body 3 is inserted into the axial center of the beading tube 2.

Reference numeral 8 denotes a lifting motor installed on a support stand 9 at the top of the ball barrel 2, and the upper end of the shaft core rod 3a of the spiral body 3 is connected to the output shaft 10 of this motor via a chain coupling 11. has been done. Reference numeral 12 denotes an outlet formed on the peripheral wall near the upper end of the pachinko tube 2, and 13 denotes an intake port formed on the peripheral wall near the lower end of the pachinko tube 2. In order to separate the polishing pellets P from the polishing pellets P, a sorting device 14 having a screen at the bottom is provided. Further, below the sorting device 14, a hopper 15 is provided for collecting the ball pellets P separated from the pachinko balls B by the screen. Inside the hopper 15, collection passages 26 are defined in a staggered manner by mesh plates 16, such as wire mesh, arranged at an alternating angle. Dirt adhering to the Tamama pellets is allowed to fall downward from the mesh plates 16 and collected. It is adapted to be collected in a device 17. Incidentally, although not shown in the drawings, the dust collection device 17 is provided with a dust collection fan and a dust collection bag.

18 is the base 1 in communication with the intake port 13 of the Tamama tube 2.
