Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention introduces pachinko balls and Tamama pellets into a lifting cylinder, and rotates a spiral coil inserted into the lifting cylinder to transport pachinko balls. The present invention relates to a pachinko ball lifting device which purifies the ball pellets while lifting them, and when the ball pellets become dirty, they are guided to a cleaning part to remove the dirt and are again supplied to the lifting tube for circulation.

[Prior Art] Conventionally, as described in Japanese Patent Laid-Open No. 59-80276, this type of pachinko ball lifting device has been used to lift pachinko balls while polishing them with an abrasive material, and also remove dirty abrasive materials. It is known that the abrasive is purified by an abrasive recycling machine and recycled for use.

[Problems to be Solved by the Invention] In the conventional pachinko ball lifting device, even if the abrasive material is not contaminated, the surface layer is scraped off by the abrasive material regenerator and the abrasive material is purified. There was a problem in that the abrasive material was severely worn out and had to be replaced in a short period of time, making it extremely uneconomical. In addition, since the abrasive shavings are simply sucked and collected by the air flow, relatively large shavings are not sucked and collected and are mixed into the pachinko ball again with the abrasive. There was a problem in that the cleaning effect of the pachinko balls was lowered due to storage. According to the present invention, the Tamama pellets separated from the pachinko balls can be recycled as they are, or sent to a cleaning section and circulated while being purified, so that the Tamama pellets can be recirculated and used efficiently depending on the dirtiness of the Tamama pellets. To provide a pachinko ball lifting device which can effectively collect shavings of tamama pellets and significantly improve the cleaning effect of pachinko balls.

[Means for Solving the Problems] In order to achieve the above object, the pachinko ball lifting device of the present invention has a spiral coil inserted therein, and the rotation of the spiral coil stirs the tamama pellets and the pachinko balls. A separation section for pachinko balls and tamago pellets is installed at the top opening of the lifting tube that lifts the pellets while mixing, and a horizontal feeding tube is connected to the lower end with an inlet for pachinko balls and a supply port for tamama pellets. The cross-feeding tube includes a cylindrical body having a plurality of cutting grooves formed on its outer peripheral surface and communicating with the cross-feeding tube;
A box having a closed structure that houses the cylindrical body therein and is defined by the cylindrical body into an upper cavity and a lower cavity, a rotating member inserted into the cylindrical body, and a rotating member that includes the rotating member. A cleaning part consisting of a rotating motor is provided, and a box-shaped drawer is arranged in the lower empty space of the box body so that it can be taken out and put in freely. A dust collection port communicating with the intake port and the upper cavity is provided, and the dust collection port and the dust collector are connected via a suction pipe, and the sorting section and the supply port of the horizontal feeding cylinder are connected by a Tamama pellet circulation pipe.

[Operation] Pachinko balls and Tamama pellets are fed into the lifting cylinder from the supply port of the horizontal feeding cylinder, and are pumped upward while being stirred and mixed by the rotation of the spiral coil. Tamama pellets are separated. When the Tamama pellets are less contaminated, the opening/closing shutter of the Tamama pellet circulation pipe is opened to circulate the Tamama pellets directly to the supply port.
When the Tamama pellets become dirty, the opening/closing shutter of the branch pipe is opened to guide the Tamama pellets to the clean section.

The dirty ball pellets led to the cleaning section are moved while coming into contact with the blade grooves of the cylindrical body due to the rotation of the rotating member, and the dirt on the surface of the pellets is scraped off and purified. Relatively large shavings fall from the blade groove of the cylindrical body into the box-shaped drawer below, and fine shavings are collected by the suction action of the dust collection port from the upper cavity of the box body through the suction pipe and into the dust collector. It will be done. Thereby, the shavings can be completely separated and removed from the ball pellets, and the cleaning effect of the pachinko balls can be further improved.
