Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a polishing device for bullets for game machines, such as pachinko balls or throttle machine metals.

(Prior art) In this type of polishing machine, the abrasive material is made of small particles such as nylon resin, and therefore the abrasive material must be replaced frequently.
At this time, the abrasive is generally supplied into a mixing casing formed in the abrasive cylinder using a bucket or the like.

(Problems to be Solved by the Invention) Therefore, there have been disadvantages in that it takes time and effort to supply the abrasive and it is troublesome to replace the abrasive. The present invention aims to improve such disadvantages.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained using FIGS. 1 and 2 corresponding to the embodiments.
In the present invention, a cassette box 8 is formed with an abrasive inside and a discharge port 9 that can be opened and closed on the bottom plate. Supply port 5 opened in the upper wall of
It is characterized by being removably attached to match the .

(Function) According to the present invention, the abrasive is placed inside the abrasive by the above-mentioned means, or the set box 8 is set on the mixing case 3, and when exchanging the abrasive, for example, the abrasive is removed from the abrasive outlet provided in the abrasive case 1. After taking out the abrasive material, the outlet 9 on the bottom plate of the cassette box is opened to supply new abrasive material from the box 8 into the mixing case 3. After the supply is finished, the box 8 is removed from the mixing case 3. The box 8 is then removed and a new box 8 is installed.

(Example) An example of the present invention will be described below with reference to the drawings.
Reference numeral 1 denotes a polishing tube, and 2 denotes an abrasive circulation pipe. A mixing case 3 is provided in communication with the lower ends of the polishing tube 1 and the circulation pipe 2, and a cassette box, which will be described later, is installed on the upper wall of the mixing case 3. An abrasive supply port 5 is opened in the mixing casing 3 so as to open on the box engaging part 4, and a supply port 5 for the abrasive is opened on one side wall of the mixing casing 3. A bullet guide path 6 and an input port 7 connected to the guide path 6 are provided.

Reference numeral 8 designates a cassette box for abrasive material, and the box 8 has a lid 8a that can be opened and closed on its top plate, and has a discharge port 9 opened in its bottom plate, and the discharge port 9 slides on the opening surface. The box 8 is provided to be openable and closable by a sliding plate 10, and the box 8 is connected to the box engaging portion 4 so that the discharge port 9 coincides with the supply port 5.
It is detachably attached to the

In the figure, reference numeral 11 indicates a rotating coil spring for feeding provided in the mixing housing 3, 12 a motor thereof, 13 a rotating coil spring for lifting provided in the polishing cylinder 1, and 14 an abrasive material outlet.

(Effect of the invention) As described above, according to the present invention, a cassette box 8 containing an abrasive material and having a discharge port 9 which can be opened and closed on the bottom plate is formed, and the box 8 is placed on the mixing case 3 formed in the abrasive cylinder 1. , the discharge port 9 is connected to the mixing cabinet 3.
Since it is removably attached to match the supply port 5 opened in the upper wall, the supply of abrasive material into the mixing case 3 is performed by opening the discharge port 9 of the cassette box 8, thereby making the supply smooth. At the same time, the cassette box 8 can be easily handled and the abrasive can be easily replaced.
