DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus suitable for continuously polishing a large number of small and medium-sized products.

[0002]

2. Description of the Related Art Conventionally, as this type of shot blasting apparatus, a product is supplied from an opening at one end and discharged from an opening at the other end to a rotatable horizontal rotating drum. In general, the product is agitated by the drum, and the blast material is projected toward the product in the rotating drum from the other end opening side.

[0003]

However, in such a conventional shot blasting apparatus, it is very difficult to uniformly clean the entire surface of a large number of products. If the gate section is integrated and the shape is complicated, there is a problem that a plurality of castings are entangled and joined together during stirring, and as a result, uneven polishing is more and more generated. The present invention has been made to solve the above problems.

[0004]

In order to achieve the above object, a continuous shot blasting apparatus according to the present invention comprises:
Inside the cabinet, there is space for one product
That a number of a row side by side cylindrical rotating body formed on the body portion to the recess, rotatably in a vertical plane, in the vicinity of the recess ascending side side interruption of the cabinet, against the one of the recess A supply port for supplying one of the products of the final cleaning is formed, and a projection material projection mechanism is installed on the ceiling of the cabinet. An outlet for discharging products is formed.

[0005]

In the apparatus constructed as described above, after rotating the rotating body and driving the blasting material projecting mechanism, one product is supplied from the supply port to the recess of the rotating body. When the product is continuously supplied in such a manner that the product is supplied, the product in each recess receives the blast material while being tilted by the recess, is cleaned and then discharged from the discharge port.

[0006]

An embodiment will be described with reference to the drawings. As shown in FIG. 1 which is a longitudinal sectional view, a cylindrical rotating body 2 is supported by a rotating shaft 3 at a central portion inside a cabinet 1 constituting a cleaning chamber, and is rotated counterclockwise in a vertical plane. It is arranged so as to be rotatable in the direction, and as shown in FIG.
A deceleration unit that penetrates the cabinet 1 from side to side and is fitted on both sides to bearing units 6 and 7 mounted on the outer surface of the cabinet 1 via brackets 4 and 5, and the right end is disposed on the bracket 5. The output shaft of the motor 8 is connected to the output shaft via a shaft joint 9. As shown in FIG. 1, a plurality of recesses 10, 10 having a space for accommodating one product are formed in a row on the body of the rotating body 2, and each recess 10 has a bottom surface. Has a rectangular shape and is concentric with the rotating body 2, and the front surface 10 a side and the rear surface 10 b are respectively inclined toward the front side or the rear side when viewed from the turning direction of the recess 10 to form an inverted octagon as a whole, In addition, the front surface 10a is elongated so that the product can be easily discharged from a discharge port 11 described later.
As seen from the turning direction of the dent 10, the left and right side surfaces 10c, 10c are also inclined upwardly at an angle of about 15 degrees so as to form an inverted octagon as a whole. After rebounding 10c, 10c, the product is properly hit.

As shown in FIG. 1, a supply port 11 for supplying unpolished products to the recess 10 is provided near the middle of the cabinet 1 on the right side (the rising side of the recess 10). The mouth 11 can supply one product to one recess 10. As shown in FIG. 1, the ceiling of the cabinet 1 is elevated so that the projection material projecting mechanisms 12, 12 can be installed facing the recesses 10, 10 that have been swiveled to the upper position in the rotating body 2. The ceiling portion has three pairs of projection material projecting mechanisms 12, 1
2 are installed respectively. In addition, the blast material projection mechanism 1
2 is a centrifugal projection type, and as shown in FIG. 2, the projected projection material is directed so as to be diffused in the left and right direction as viewed from the turning direction of the recess 10. Two units are provided.

As shown in FIG. 1, a discharge port 13 for discharging the polished product from the recess 10 is provided near the middle stage on the left side of the cabinet 1 (downward side of the recess 10).
Are formed, and the outlet 13 corresponds to one recess 10. A perforated steel plate 14 is stretched horizontally at the outlet 13. Further, a belt conveyor 1 for collecting the projected blast material is provided below the cabinet 1.
5 are installed. 16 is a rubber goodwill seal, 17 is a product carrying conveyor, and 18 is a product carrying conveyor.

Next, the operation of the thus configured device will be described. By driving the motor 8, the rotating body 2 is rotated in the counterclockwise direction in FIG. 1 to rotate the recesses 2, 2 in the counterclockwise direction.
Is driven to project the blasting material toward the depressions 10, and the belt conveyor 15 is driven. Under this condition, when uncleaned products are supplied into the recesses through the supply port 11 via the product carrying conveyor 17, the products are supplied one by one to one recess 10, With the turning of the dent 10, the projections are sequentially moved to the position immediately below the projecting material projecting mechanisms 12 and 12, and the turning of the dent 10 causes the front surface 10a and the rear surface 10b to be tilted and fall down. 12, 12 or from left and right side 10
Receiving the blast material that bounces c and 10c, the whole is polished almost uniformly, and then discharged from the discharge port 13. Thus, a large number of products are continuously cleaned.

[0010]

As is apparent from the above description, according to the present invention, a plurality of recesses having a space for accommodating one product and having an inverted octagonal wall surface are formed in a row to form a body portion. A cylindrical rotating body is installed inside the cabinet so as to be rotatable in a vertical plane. Further, product supply and discharge ports are formed on the sides of the cabinet, and projectile material is projected on the ceiling of the cabinet. Since the mechanism is installed, a large number of products can be polished while falling down one by one in the dent. This has the effect of uniformly cleaning the entire surface of the product.
