Abstract

PURPOSE:To reduce the rotation power of a rotary drum and to prevent the occurrence of a trouble during output of a product, by a method wherein a shot projection device is mounted in a position obliquely upwardly of a cabinet, and the rotary drum is disposed in a cabinet in a manner that it is vertically rotatable and horizontally rotatable in a 90 deg. arc. CONSTITUTION:After an on-off door 17 is opened, a driven device is driven to revolve a rotary drum 9 in 90 deg. arc to a position situated facing a door 17. The rotary drum 9s is brought into an up state, and a part of the tip thereof is protruded in a cabinet 1. Products to be ground are charged in the drum 9. The drum 9 is reversed, and is moved to a position situated facing a shot projection device 3 in an up inclined state to close the door 17. With a motor 10 with a reduction gear driven, the drum 9 is rotated, and through drive of a shot circulation device and a shot projection device 3, the products are ground. After grinding, the door 17 is opened, the drum 9 is revolved in a 90 deg. arc and returned to a position situated facing the door 17, and the drum 9 is inclined downward through a rotation frame 6 to discharge the products.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rotary drum type shotplast apparatus whose cleaning chamber is constituted by a tiltable rotary drum.

(Prior Art and Problems) Conventionally, there is a rotating drum type shot blasting device as disclosed in Japanese Patent Publication No. 58-50829, but in this shot blasting device, the rotating drum is mounted on two vertical surfaces. It was constructed to tilt in one dimension, and a large amount of power was required to rotate the rotating drum. Furthermore, since the rotating drum rotates within the cabinet, there is a problem in that the products hit the cabinet when being carried out, causing various troubles.

(Purpose of the invention) The present invention has been made in view of the above circumstances.

(Configuration of the Invention) Hereinafter, the configuration of the present invention will be described in detail based on drawings of embodiments. (1) is a cabinet, and a shot projecting device (3) equipped with an impeller (2) is mounted on the diagonally upper right side of the cabinet (1). An opening (17a) with an opening/closing door (17) is formed in the front of the cabinet (1), and products are supplied and discharged from the opening. Also, the cabinet (
A vertical rotating shaft (4) is rotatably mounted on the ceiling of the vertical rotating shaft (4), and a gate-shaped frame (5) is fixed near the center to the lower end of the vertical rotating shaft (4). ) between the lower ends of the rotary frame (6) is the support shaft (15) (16)
At one end of the support shaft (15) is a piston rod of an electric cylinder (not shown) pivoted on the side of the portal frame (5). The tip of the rotary frame (6) is connected to a bottle via an arm (not shown), and the rotary frame (6) can be rotated up and down by the expansion and contraction operation of an electric cylinder. Further, a rotating shaft (8) is rotatably mounted in the center of the rotating frame (6) via a bearing unit (7), and a cleaning chamber is configured at one end of the rotating shaft (8). Rotating drum (9)
A large number of small holes (not shown) are bored in the body of the rotating drum (9).

In addition, the other end of the rotating shaft (8) is connected to the output shaft of the rotating frame (6) (a motor with a reducer (10) installed therein).
1) (12) and a roller chain (13), and the rotating drum (9) is connected to a motor (12) with a reduction gear.
0) rotates at a low speed.

(14) is a screw conveyor. In addition, the opening (
17a), the rotating drum (19) has an opening (17a).
The rotary drum (19) is provided in such a position that the tip of the rotary drum (19) protrudes from the opening (17a) when the rotary drum (19) is rotated in the direction shown in FIG.

(Action of invention) Next, the operation of the device configured as described above will be explained.

First, after opening the opening/closing door (17), a drive device (not shown) is driven to turn the gate frame (5), rotating drum (9), etc. 90 degrees to a position facing the opening/closing door (17), and then In Figure 3, the rotating drum (9
) in a diagonally upward position toward a conveyor (not shown) for carrying in the product to be polished, a part of the tip of the rotating drum (9) protrudes from the cabinet (1), and then the rotating drum (9) is loaded with the product to be polished. Charge the specified amount of cleaning products. Next, the drive device (not shown) is reversely driven to reversely rotate the rotating drum (9) by 90 degrees, and the rotating drum (9) is moved to a position facing the shot projection device (3) while tilted upward. and close the opening/closing door (17). Next, the motor (10) with a speed reducer is driven to rotate the rotary drum (9) to agitate the product therein, and the shot circulation device and shot projection device (3) (not shown) are driven to circulate the shots. The product is blasted into the rotating drum (9) while the product is being polished. After polishing the product, the drive of the shot projection device (3) and the motor with reducer (10) is temporarily stopped, and then, after opening the opening/closing door (17), the drive device (not shown) is driven to rotate. Rotate the drum (9) 90 degrees and open/close the door (17)
Return to the position facing the

Next, the motor with a speed reducer (10) is driven, and an electric cylinder (not shown) is extended to rotate the rotating drum (10).
9) is tilted downward via the rotating frame (6),
The polished product in the rotating drum (9) is discharged onto a conveyor (not shown). After the product is discharged, the motor with reducer (
10) is stopped, and an electric cylinder (not shown) is contracted to tilt the rotating drum (9) upward again, completing the -cycle.

(Effects of the Invention) As is clear from the above description, the present invention includes a shot projection device (3) mounted diagonally above the cabinet (1), and a rotary drum (3) mounted inside the cabinet (1).
9) is arranged so that it can move up and down and rotate horizontally by 90 degrees, so the range of rotation of the rotating drum (9) is narrowed, the power required for this can be greatly reduced, and the product can be easily moved when transporting the product. There will be no troubles with the cabinet, etc.
It has various effects.
