Abstract

PURPOSE:To form a conveyer into small size and to narrow its setting area, by providing two discharge ports in a fork structural hopper main unit and shot blast machines respectively in the bottom of the two discharge ports and setting up this conveyer, which is for conveying a process-finished product, between bottom positions of these shot blast machines. CONSTITUTION:A product to be processed is continuously supplied coming from a belt conveyer 1, and a product distributing plate 4 of a hopper 2 sorts the product alternately into a left chamber 13a and a right chamber 13b of a hopper main unit 3 charging these chambers with the product. Next contracting a cylinder 6a to open a discharge port of the left chamber 13a, the product charged into the chamber 13a, is contained in the rotating drum 9a of the corresponding shot blast machine 7a and on performing shot blasting is discharged onto a conveyer 10. Similarly the right chamber 13b is charged with the product, and a shot blast machine 7b mounted is also changed with the product is a rotary drum 9b staggering the time, thus performing shot blasting and discharging the process-finished product onto the common conveyer 10.

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. Related to shot blasting equipment.

(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, when the amount of product to be processed is large, the shot blasting machine becomes large, and the conveyor for carrying the product in and the conveyor for carrying it out become large, resulting in problems such as the installation space and equipment cost becoming extremely high. was there.

(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. (1) is 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 bifurcated hopper body (3) whose lower part is divided into a left chamber (13a) and a right chamber (13b) and has discharge ports formed on both left and right sides, and a hopper body (3). 3) a product distribution plate (4) provided on the upper part of the bifurcated structure so as to be rotatable left and right, and opening/closing doors (5a) (5b) that are pivotally supported on the hopper body (3) to open and close the discharge port;
Pivotally supported on the hopper body (3) and opening/closing door (5a) (5
b) and cylinders (6a) and (6b) connected by pins. (7a) (7b) are shot blasting machines placed on both the left and right sides of the hopper (2), and these shot blasting machines (7a) (7b) are equipped with rotating drums (9a) (9b) that constitute the cleaning chamber. is the cabinet (8
a) Rotatably disposed within (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 machine (7a) and the shot blasting machine (7b) at a lower position. Note that (lla) and (llb) are the shot projection mechanisms (12a and 12b) attached to the shot blasting machine (7a) and (7b), respectively.
(7b) is a shot recovery circulation mechanism attached to the shot recovery circulation mechanism.

(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), and the product distribution plate (4) is alternately rotated left and right at predetermined intervals to supply the hopper body. (3) A predetermined amount of product is alternately introduced into the left ventricle (13a) and the right ventricle (13b). Further, the belt conveyor (10) is continuously driven. Under this condition, first, the cylinder (6a) is contracted and the left ventricle (13a) is activated.
) and charge the product in the left chamber (13a) into the rotating drum (9a) of the shot blasting machine (7a).
Subsequently, the rotating drum (9a) is attached to the shot projection mechanism (ll
Turn it 90 degrees to the a) side. Next, the shot projection mechanism (lla) and the shot circulation mechanism (12a) are driven to circulate the shot and project the shot into the rotating drum (9a) to shot blast the product. After completing the shot blasting of the product, the shot projection mechanism (lla)
Then, the drive of the shot circulation mechanism (12a) is temporarily stopped, and then the rotating drum (9a) is moved 9 towards the hopper (2).
Rotate 0 degrees in the opposite direction.

Thereafter, the rotating drum (9a) is tilted downward to discharge the shot blasted products onto the conveyor (10). After the product has been discharged, the rotating drum (9a) is tilted upward and 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).

The conveyor for loading and unloading products is a belt conveyor (1).
It is not limited to (10).

(Effect of the invention) As is clear from the above explanation, the present invention
A rotary drum (9a) is arranged below the discharge port.
Shot blasting machines (7a) and (7b), each of which has a vertically movable and rotatable 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). Because of the installation, even if there is a large amount of products to be processed, they can be divided into two shot blasting machines and shore blasted. This has excellent effects, such as being able to reduce the space required for installation, as well as reducing the space required for installation.
