[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shot blasting apparatus which throws a product into a blasting room constituted by an endless tumbling belt and projects a shot while rolling the product in the blasting room to perform blasting.

Conventionally, in this type of shot blasting apparatus, products are carried out by reversing an endless tumbling belt to scoop up the products from the cleaning chamber. However, when carrying out such a product, if the product is small and easily rolled, even if it is scooped up by the tumbling belt, it rolls on the way and returns to the bottom of the cleaning chamber to completely carry out the product. There was a problem that it was difficult for the worker to scrape out by hand at the final stage. The present invention has been made in view of the above-mentioned problem, and has as its object to provide a shot blasting apparatus capable of fully automatically carrying out a product after blast processing.

[0003]

In order to achieve the above object, a shot blasting device according to the present invention is provided with an endless tumbling belt, a product entrance and exit position in a cabinet, a depth position thereof, and a depth upper position. Disposed to move the tumbling belt forward and backward 3
A conveyor wheel, a blasting chamber formed by recessing the tumbling belt, and a shot projector for projecting a shot toward the blasting chamber; and a shot blasting apparatus comprising: The conveyor wheel provided is an electromagnet wheel.

[0004]

According to the present invention, the blasted product is picked up from the cleaning chamber by the reverse rotation of the tumbling belt and then magnetically attached to the electromagnet wheel and moved by adopting the above-mentioned solution. Since the product is carried out from the entrance, the product after the blast processing is carried out automatically and reliably.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, an elevator door 2 for opening and closing a product entrance is provided at an upper half position on the front surface of a cabinet 1,
The ceiling is provided with a shot projector 3 for projecting a shot toward a later-described polishing room 9 in the cabinet 1. Conveyor wheels 4, 5, and 6 are disposed in the cabinet 1 at a product entrance position, a depth position thereof, and an upper depth position thereof so as to be able to rotate forward and backward, and one of the conveyor wheels is provided. Are connected to a driving device (not shown) so that they can rotate forward and backward. Further, an endless tumbling belt 7 is wrapped around the conveyor wheels 4, 5, 6, and the tumbling belt 7 is formed with a hollow by a rotating side plate 8 to constitute a cleaning chamber 9. In the drawing, reference numeral 10 denotes a separation plate portion.

[0006] In the apparatus constructed as described above, a product is carried into the cleaning chamber 9 in the state shown in FIG. 1, the door 2 is closed, and a conveyor wheel (4, 4) connected to a driving device (not shown) is used.
Shots are projected from the shot projector 3 in a state in which the endless tumbling belt 7 is normally rotated to rotate the product W in the cleaning chamber 9. I have. This state is continued for a certain period of time and the product W
When the blasting process is completed, the driving of the shot projector 3 is stopped, the door 2 is opened, and the driving conveyor wheel (4, 4) is opened.
The tumbling belt 7 is rotated in the reverse direction by rotating the tumbling belt 7 in the reverse direction, and a current is supplied to the electromagnet wheel 4 so that a current is supplied to the electromagnet wheel 4 to make the electromagnet work.

As a result, the product W in the cleaning chamber 9 is scooped up by the tumbling belt 7 and moves to the product entrance / exit side, where it is prevented from rolling by the magnetic force of the electromagnet wheel 4, and the tumbling belt is kept as it is. 7 and the scraper-shaped separation plate 1 near the product entrance
Due to 0, the tumbling belt 7 is separated from the tumbling belt 7 and carried out. By carrying out such an unloading operation for a certain period of time, the blasted product W is scooped up from the cleaning chamber 9 by the tumbling belt 7, is securely magnetized, moves as it is, and is separated and transported at the product entrance.

[0008]

[Effects of the Invention] As is clear from the above description, the present invention uses an electromagnet wheel for the conveyor wheel arranged near the product entrance, so that the product is scooped up from the cleaning chamber and securely magnetized by the electromagnet. Because they are transported and unloaded, it is possible to fully automate the unloading of products,
The effect is significant.
