Abstract

PURPOSE:To permit the uniform polishing for the whole surface of a decorative article whose finishing state is attached with importance, by rolling a polished piece supporting lever installed in the vicinity of the top point inside a barrel having a polygonal section, in proportion to the revolution of the barrel. CONSTITUTION:When a barrel polishing apparatus is operated, a power switch is turned ON, and after a polished article is fed into a barrel 10, a polished piece is set onto a supporting lever and installed onto the installation apparatuses at eight positions in the barrel 10. Then the cover of the barrel is closed, and an emergency stop lamp in OFF state is confirmed, and polishing work is started by pushing a barrel polishing apparatus starting button, and the polishing time is set onto a normal/reverse timer. When the polished piece is taken- out after the completion of polishing, the manual adjustment to set the mark on a sprocket to a prescribed position is performed, and the cover of the barrel 10 is demounted, and the polished piece is taken-out, and thus one cycle is completed. Since the supporting lever is installed in the vicinity of the top point of a barrel polygon, the polished article can be polished uniformly at the reflux point where the polished article is dropped and lifted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a barrel polishing device, and more particularly to a barrel polishing device applied to an article whose entire surface should be uniformly polished, such as an eyeglass frame or a watch frame.

Hitherto, several types of barrel polishing loads of this type are known. Patent No. 181479 (Showa 1
(August 4, 2013), ``Inside a rotary cylinder that rotates in a certain direction, a frame for holding an object to be polished, which rotates in the same direction as the cylinder, is placed in close proximity to the cylinder wall in the axial direction of the cylinder. A "rotary sander which is pivotally supported on the body wall" is described. Also, Jikoko Sho 51-414
Publication No. 03 describes "a polishing/cleaning device in which a wire mesh drum and a vane plate are rotated inside a rotating drum".

However, with these polishing devices, the K applied to decorative articles such as eyeglass frames or watch rims where a 9 finish is important is not necessarily sufficient.

The present invention is constructed from the above points of view, and is a further improvement of Utility Application No. Sho SS-5S9ST and Japanese Patent Application No. Sho 55-44986, which were previously filed by the present applicant.

In view of the above, the present invention provides a barrel polishing device in which a support base for a part to be polished is mounted inside a barrel and is configured to roll in proportion to the rotation of the barrel, the barrel having a polygonal cross-section,
The part-to-be-polished support needle is arranged near the apex of the polygon of the barrel.

Furthermore, the plurality of supports are alternately electrically connected;
It is configured to cause an emergency stop when an electrical short circuit is formed between alternate support rods, such as when a piece to be polished falls off from the support punch.

Further, the part-to-be-polished support needle and the barrel are connected by a power transmission means, and a specific driving sprocket among the plurality of part-to-be-polished support needles is marked with a fixed position stop mark.

When the barrel polishing device of the present invention is rotated in the direction R shown in FIG. 6, the polishing medium 15 within the barrel 10 circulates within the barrel 1o as shown by arrow FK. The polishing medium 15 inside the barrel 10 is lifted in the rotation direction R by the rotation of the barrel 1o, slides down due to gravity near the central axis, and reaches the lowest vertex of the polygon of the barrel 1° (in FIG. 6). 16), and the side of the barrel 10 (1 in Fig. 6)
7) K collides and is further lifted by the rotation of the barrel 10 and circulated. In this, the part to be polished supporting punch 11
Since the point 0 is provided near the vertex of the barrel polygon, the part to be polished is uniformly polished at the reflux point where the polishing medium 15 falls, is reversed and lifted.

This is part 6-a, 6. This will be explained while comparing with the conventional example in Fig.-b. FIG. 6-a is a diagram schematically illustrating the present invention, and shows that the part-to-be-polished support needle 110 is well polished at the recirculation point of the reversal of the drop of the polishing medium 15.

Fig. 6-b shows a case in which one support lever 110 is attached near the center of the polygonal side of the barrel lO as in the conventional case. After the polishing medium 15 collides with the side 17 beyond the vertex 16 of the polygon and consumes energy, it reaches the polished part support #llo.

Since the present invention is configured as described above, the part to be polished can be polished satisfactorily and uniformly.

Furthermore, since the present invention has a safety device, even if the polished part should fall off, it can be detected and an emergency stop can be performed.

Furthermore, the present invention allows the drive sprocket of the support punch to always be stopped at a fixed position by a fixed position stop mark.
