Description

[Detailed description of the invention] <Industrial application field> The present invention is based on the abrasive grain tray of a sorting device installed at the top of a lifting pipe that polishes and transports pachinko balls and abrasive grains while stirring and mixing them. Inside, dust such as abrasive powder and other dust mixed with abrasive grains is forcibly removed by suction using a dust collector, and the forcibly suctioned and removed dust is stored in a dust storage chamber. The present invention relates to a pachinko ball lifting device characterized by the following features.

<Prior art> A sorting device for separating pachinko balls and abrasive grains is installed at the top of a lifting pipe that has a spiral body inside and agitates and mixes pachinko balls and abrasive grains and transports the pachinko balls while polishing them. A pachinko ball lifting device in which a tray for separating abrasive grains and dust is provided in the sorting device is described in, for example, Japanese Patent Application Laid-open No. 70968/1983.

The pachinko ball lifting device described in the above-mentioned publication has a spiral body inside a cylinder whose lower part is arc-shaped, and the pachinko balls are stirred and mixed with abrasive grains and pachinko balls inside the cylinder. Pachinko balls and abrasive particles are separated from each other by a sorting device having a sieve, and the abrasive particles and dust are separated by their own weight inside a hopper of the sorting device. It is.

<Problems to be solved by the invention> However, with the conventional pachinko ball lifting device described above, although it may be possible to remove dust that is a certain size and weight from the abrasive grains inside the sorting device, it is possible to remove dust that is small and light. Dust (dust, fine particles of abrasive grains, etc.) flies up inside the sorting device and cannot be separated and removed sufficiently.

Therefore, these small dust particles re-adhere to the surface of the abrasive grains and pachinko balls in the sorting equipment, and not only do they stain the various gutters and the surface of the pachinko machine playing area, but also the abrasive grains with the small dust re-adhered to them. In this case, no polishing effect can be expected on the pachinko balls during the lifting process inside the cylinder.

Furthermore, in the sorting device in the conventional pachinko ball transport device described above, the dust falls through the mesh sieve and collects in the tray, and is disposed of at an appropriate time. However, if you forget or dispose of it at the wrong time, dust will overflow from the tray and flow into the abrasive particle collection pipe. Since the abrasive particles flow down into the hopper together with the abrasive particles, the abrasive particles become contaminated at an early stage. Further, although a dust receiving tray is provided inside the hopper of the abrasive grains, the dust cannot be removed reliably and sufficiently.

This invention forcibly removes not only the relatively large dust present inside the abrasive grain tray but also particularly fine dust (dust, etc.) that flies up in the air inside the sorting device that separates pachinko balls and abrasive grains. To prevent pachinko balls and abrasive grains from being contaminated by fine dust, or from causing fine dust to fly inside a pachinko parlor and deteriorating the atmosphere in the pachinko parlor.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention provides a lifting pipe which has a spiral body inside, stirs and mixes pachinko balls and abrasive grains, and lifts the pachinko balls while polishing them. A sorting device is provided on the top of the abrasive grain tray with a screen-like gutter that allows abrasive grains to pass through but does not allow pachinko balls to pass through the open upper surface of the abrasive grain receiver, and inside the abrasive grain receiver of the sorter, a A dust suction section is provided with a mesh plate that allows dust to pass through but does not allow abrasive particles to pass through, and one end of the dust suction gutter is connected to a suction hole provided at a low position of the dust suction section. The other end of the gutter is connected to a dust collector that forcibly sucks the dust inside the abrasive grain tray and the dust suction section, and a dust storage chamber is installed adjacent to the dust collector, and a dust collector is connected to the top of the lifting pipe. The pachinko balls to be discharged and the abrasive grains are separated by a screen-shaped gutter of the sorting device, and the abrasive grains and dust fall into the inside of the abrasive grain receiver.
During the falling process of abrasive grains and dust, only the dust is forcibly sucked into the dust suction part by the suction action of the dust collector.
The present invention is characterized in that the dust is guided to a dust collector through a suction gutter, and is stored in a dust storage chamber from the dust collector.

The above-described dust collector 14 forcibly sucks the inside of the dust suction section 11 and the inside of the dust suction section 11 through the dust suction gutter 13, and collects the dust c existing inside the dust suction section 11 and the dust suction gutter 13. is removed by suction through the dust suction gutter 13. Further, the dust storage chamber 15 stores therein the dust c sucked by the dust collector 14.

The lower part of the abrasive grain tray 10 described above has an abrasive grain outlet 10', and a first abrasive grain flow down trough 12 and a second abrasive grain flow down gutter 12 are connected to this outlet 10' via a switching valve device 21.

The dust collector is characterized in that the dust is guided to a dust collector through a suction gutter, and is stored in a dust storage chamber from the dust collector.

Therefore, with the present invention, any fine dust can be reliably removed by suction, whereas in the past, relatively fine and light dust would fly up in the sorting device and re-adhere to pachinko balls or abrasive grains. , it is possible to reliably eliminate the drawbacks of replenishing pachinko balls with dust attached to them, which stains the surface of the game board, and balls clogging in various gutters.
Furthermore, it is possible to reliably eliminate the significant deterioration in the polishing effect within the lift pipe due to fine dust adhering to the circulating polishing particles.

In addition, even if fine and light dust is stirred up inside the sorting device, the dust will not leak outside through the gaps in the sorting device, so it will not worsen the atmosphere (air conditioning) inside the pachinko parlor, and the accumulated dust will not leak out from the gaps in the sorting device. When collecting the dust, it can be easily taken out because the dust storage chamber is provided in the lower part of the interior of the row of pachinko machines, making it extremely simple and of high practical value.
