Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention organically combines two shot blasting machines with one product loading conveyor and one product unloading conveyor to increase productivity. This invention relates to a shot blasting device.

(Prior Art and Problems) In conventional shot blasting equipment, a single shot blasting machine is generally provided with a conveyor for carrying in the product and a conveyor for carrying out the product, respectively. Therefore, if the amount of product to be processed is large, the shot blasting machine will not only be large, but the conveyor for carrying in and taking out the product will also be large, which will require a large amount of installation space and equipment costs. There was a problem.

(Object of the Invention) The present invention has been made to solve the above problems.

(Configuration of the Invention) Hereinafter, the configuration of the present invention will be described in detail based on drawings of embodiments. Reference numeral 1 denotes a belt conveyor for conveying products to be shot blasted, and a hopper machine 2 is disposed below the discharge end of the belt conveyor 1. The hopper 2 has a hopper main body 3 with a bifurcated structure in which the lower part is divided into a left chamber 13a and a right ventricle 13b and has discharge ports formed on both left and right sides, and a hopper main body 3 with a bifurcated structure in the upper part of the hopper main body 3. A movably provided product distribution plate 4 and an opening/closing door 5 that is pivotally supported on the hopper body 3 and opens and closes the discharge port.
a, 5b, and cylinders 6a, 6b which are pivotally supported on the hopper body 3 and connected with pins to the opening/closing doors 5a, 5b.
It is made up of. 7a and 7b are shot blast machines placed on both the left and right sides of the hopper 2;
The shot blasting machines 7a, 7b have rotary drums 9a, 9b constituting a cleaning chamber connected to a cabinet 8.
It is rotatably arranged within a and 8b. The rotating drums 9a and 9b are configured to be able to tilt up and down and also to be able to rotate 90 degrees in the horizontal direction. Further, a belt conveyor 10 for conveying shot blasted products is installed between the shot blasting machines 7a and 7b at a lower position. Note that 11a and 11b are shot projection mechanisms attached to shot blasting machines 7a and 7b, and 12a and 12b are shot blasting mechanisms attached to shot blasting machines 7a and 7b.
This is a shot recovery circulation mechanism attached to a and 7b.

(Operation of the invention) Next, the operation of the device configured as described above will be explained. The belt conveyor 1 is continuously driven to continuously supply a certain amount of products to the hopper 2,
In addition, the product distribution plate 4 is rotated alternately left and right at predetermined intervals to distribute the left chamber 13a and right chamber 13b of the hopper main body 3.
A predetermined amount of product is alternately placed in and. Further, the belt conveyor 10 is continuously driven. Under this condition, first, the cylinder 6a is contracted to open the discharge port of the left chamber 13a, and the product in the left chamber 13a is transferred to the rotary drum 9 of the shot blasting machine 7a.
Then, the rotating drum 9a is turned 90 degrees toward the shot projection mechanism 11a. Next, the shot projection mechanism 11a and the shot circulation mechanism 1
2a is driven to circulate the shots and project the shots into the rotating drum 9 to shotblast the product. After the shot blasting of the product is completed, the shot projection mechanism 11a and the shot circulation mechanism 12
The drive of the rotating drum 9a is temporarily stopped, and then the rotating drum 9a is
is reversely rotated 90 degrees in the direction of the hopper 2, and then the rotary drum 9a is tilted downward to discharge the shot-blasted product onto the conveyor 10. After the product has been discharged, the rotating drum 9a is tilted upward,
The product is charged into it in the same manner as described above. The above operations are also performed in the other shot blasting machine 7b with a predetermined time shift from that of the shot blasting machine 7a.

Note that the product loading/unloading conveyor is not limited to the belt conveyors 1 and 10.

(Effects of the Invention) As is clear from the above description, the present invention provides a product dispensing device that is provided with two discharge ports below the discharge end of a conveyor for conveying processed products, and that rotates left and right at predetermined intervals. A bifurcated hopper main body 3 provided with a plate 4 is disposed, and a rotary drum 9a,
Shot blasting machines 7a and 7b, each of which has a vertically movable and swivelable shot blasting machine 9b, are arranged, and a conveyor for transporting shot blasted products is installed between the lower positions of the shot blasting machines 7a and 7b. Even if there is a large amount of processed products, they can be shot blasted separately between two shot blasting machines, so the conveyor for transporting the processed products and the conveyor for transporting the shot blasted products can be made smaller and cheaper. This has excellent effects such as the installation space of these devices can be small.
