Benefits of technology

[0004]In view of the conventional drawbacks as described above, it is an object of the present invention to provide a projector and a shot blast machine which do not cause any damage to and can increase the durability of the impeller and the projectile.
[0005]It is another object of the present invention to provide a projector and a shot blast machine which can use the projectile with high grindability or of small particle size or low specific gravity.

Problems solved by technology

This brings a drawback that the projectile damages itself when it strikes the impeller.
Another drawback is that projectile with high grindability cannot be used, since it damages the impeller.
A still further drawback is that the impeller being used is made of metal material and heavy, requiring a large motor to drive it, high cost and the impeller being hard to rotate at high speed.

first embodiment

[0051]FIGS. 1 to 7 illustrate the present invention wherein reference numeral 1 is a shot blast machine which deburrs molded goods, treats the surface of molded goods and removes crud attached to the surface of the workpieces. The shot blast machine 1 is comprised of a housing 2; a table 4 in the form of a perforated plate or a mesh, as a support for a workpiece 3, installed into an upper portion of the housing 2; an openable door 5 attached to the housing 2 enabling placing the workpiece 3 onto and removing the workpiece 3 from the table 4; a separator 7 with a vibrating screen below the table 4 in the housing 2 and communicating with the table 4 through the hopper 6; a liquid tank 8 provided with liquid such as water, cleaning liquid or the like separated out by the separator 7 therein, a projectile tank 9 provided the projectile therein, a small particle tank 10 having small particles therein, and a large particle tank 11 provided large particles therein; a mixing tank 13 having ...

second embodiment

[0060]the present invention is shown in FIGS. 8 and 9 and is distinguished from the first embodiment by the fact that a high abrasion-resistant rubber sheet 39 is fixed to an inner wall surface of the wheel cover 23 by adhering, coating and the like in order to blast the projectile-mixed liquid to the workpiece 3 on the table from the side and upper portion of the housing 2; and the projector 15 is replaced from two projectors 15A, 15A which adhered or coated a high abrasion-resistant rubber 41 on a surface of an impeller body 40 made of metal.

[0061]A shot blast machine 1A in this way according to the third embodiment has similar advantages to that according to the first embodiment.

[0062]A third embodiment of the present invention is shown in FIGS. 10 to 12 and is distinguished from the first embodiment by the fact that a belt conveyor 31 as a supporting device is used, forming in the shape of a L-letter, capable of holding the workpiece 3 and agitating it. A shot blast machine 1B w...

fifth embodiment

[0067]A shot blast machine 1D in this way may be composed.

Abstract

Disclosed are a projector comprising an impeller rotated at high speed by a high-speed rotation driving device and a cover for covering the outer peripheral part of the impeller and having a projection material suction port and a projection material discharge port; and a blasting machine. In the projector, the entire of the impeller or the portion of the impeller with which the projection material is collided is formed of a high wear resistant rubber. It is possible to prevent the impeller and the projection material from damage, and to improve the durability of the projector. Furthermore, projection materials having high grinding property or those having fine particles and low specific gravity may also be used for the projector. Since the weight of the projector is light, it can be rotated directly by a motor at high speed and can be used under such conditions as ultra low temperature, ordinary temperature, high moisture, etc.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a projector to be used for a shot blast machine, and a shot blast machine which deburrs and treats surface of molded goods and removes crud attached to surface of workpieces.[0002]The conventional shot blast machine uses the projector with the impeller which is made of metal material. This brings a drawback that the projectile damages itself when it strikes the impeller. Another drawback is that projectile with high grindability cannot be used, since it damages the impeller. A still further drawback is that the impeller being used is made of metal material and heavy, requiring a large motor to drive it, high cost and the impeller being hard to rotate at high speed.[0003]Patent Document 1: Japanese published unexamined application H3-234470SUMMARY OF THE INVENTION[0004]In view of the conventional drawbacks as described above, it is an object of the present invention to provide a projector and a shot blast machine which...
