Cylindrical shaft (9, A pressurizing device (17) connected to the other cylindrical shaft (10) and capable of applying pressure to prevent dust from entering the gearbox (11), and a lower position of the bucket (7). From a projection material including a hopper 18 formed on the blast processing case 4 of the present invention and dust such as burrs falling from the hopper 18, a burr larger than the projection material, and a projection material smaller than the projection material Vibrating body 23 for sorting projection material having a large burr sorting vibrating body 20 having a large burr storing tank 19, a projection material storage tank 21, and a small burr storing tank 22, sorted by burrs. And a projection material 25 in the projection material storage tank 21 of the screening device 24 with a suction hose 26 to suck the projection material 25 into the bucket 7. The projection of the blasted case body 4 by the rotation of the impeller 27 A coolant supply device 30 which supplies a coolant to the projection machine 28 and the blast processing case body 4 provided in the unit, and is attached to the upper portion of the blast processing case body with an opening / closing valve 29 interposed therebetween. It consists of).

The said bucket drive device 13 is connected to the bucket drive motor 31 provided in the said drive apparatus storage case body 12, and the drive shaft 32 of this bucket drive motor 31, The said drive shaft 32 Is composed of an output shaft 33 which is output in a direction perpendicular to the axial direction of and connected to the power transmission shaft 14.

The power transmission mechanism 15 is located in the gear box 11 and the bevel gear 34 is attached to the power transmission shaft 14, and the gear box 11 to be engaged with the sovevel gear 34. It consists of a large bevel gear 35 rotatably attached to the inside, and a barrel shaft 36 having one end fixed to the large bevel gear 35 and the other end attached to the bottom surface of the bucket 7.

The bucket rotating device 16 is connected to a bucket rotating forward and reverse motor 37 provided in the drive unit housing case 12, and a drive shaft 38 of the bucket rotating forward and reverse motor 37, and An output shaft 39 output in a direction perpendicular to the axial direction of the drive shaft 38, a drive pulley 40 attached to the output shaft 39, and the one cylinder at a position corresponding to the drive pulley 40. The pulley 41 attached to the shaft 9 of the shape, the belt 42 spanning the pulley 41 and the driving pulley 40, and the position of the bucket 7 are located at the position where the projection material is projected ( A), a sensor using the pulley 41 to stop the bucket rotating forward and backward motor 37 by detecting the injection position B of the molded article to remove the burr and the discharge position C of the molded article from which the bur is removed. It consists of (43, 44, 45).

The pressurizing device 17 includes a supply hose 47 fitted with an on-off valve 46 connected to the shaft 10 in the other cylindrical shape, and nitrogen, carbon dioxide, helium and argon connected to the supply hose 47. And an inert gas cylinder 48 filled with an inert gas such as a shielding gas for welding and a cover gas for flame retardant.

The shot blasting apparatus 1 of the said structure opens the opening-closing door 3, opens the opening part 5, drives the rotating device 16 of a bucket, and rotates the bucket 7 to the position shown in FIG. In this state, the molded article 6 to remove the burr is put into the bucket 7.

Next, the bucket rotating device 16 is driven to position the bucket 7 in the blast processing case body 4, and the opening portion 5 is closed by the opening / closing door 3.

Thereafter, the coolant is supplied to the blast processing case 4 by the coolant supply device 30, and the bucket drive device 13, the projector 28, and the sorting device 24 are operated in an interlocked state, thereby providing a projector ( The projection material 25 of the projection material storage tank 21 is sucked by the suction hose 26 by the rotation of the impeller 27 of 28, and the burr in the bucket 7 is projected on the molded article 6 to be removed. . The burr removed from the projection material 25 and the molded article projected by the projector 28 falls from the hopper 18 to the sorting device 24, and the large burr sorting vibrating body 20 of the sorting device 24 is dropped. The large burr is recovered by the large burr storage tank 22, and the projection material and the small burr that have passed through the large burr vibrating body 20 are smaller than the projection material 25 by the projection material sorting vibrating body 23. Selected by the burr, the projection material 25 is accommodated in the projection material storage tank 21, the small burr in the small burr storage tank 22.

For this reason, the projection material 25 is circulated and used by the projection material storage tank 21, the suction hose 26, the projection machine 28, the blast processing case 4, the hopper 18, and the sorting apparatus 24, and a projection machine (28) Since the sorting device 24 operates in an interlocked state, the projection material 25 is not piled up on a portion, so that the blockage of the projection material 25 can be effectively prevented.

In addition, when the projector 28 is driven, the opening / closing valve 26 of the pressurizing device 17 is opened, the inert gas is filled in the gearbox 11, and used in a predetermined pressurized state.

Therefore, even when the projection material 25 is projected into the bucket 7, dust is generated, it is possible to effectively prevent dust from being inserted into the gear box 11.

In addition, when the burr is removed from the molded article in the bucket 7 by the projection of the projection material 25, the projector 28, the sorting device 24, the bucket drive device 13 is stopped and the opening / closing door 3 is opened. The rotating device 16 of the bucket is rotated as shown in FIG. 4 to discharge the molded product in the bucket 7 out of the bucket 7.

When the molded article 6 from which the burr has been removed from the bucket 7 is discharged, the rotating device 16 of the bucket is driven to rotate the molded article to remove the burr shown in FIG. As a result, the burr can be removed from the molded article with the burr.
