The drive unit 12 is connected to a rotating shaft of a drive device 12, which includes a motor or the like attached to the drive unit 12. The cabinet body 1 also has a position corresponding to the opening 11 when the tumbler 10 is rotated by the rotation shaft 2 to the inverted position shown in FIG. A window 13 for supplying and discharging products is formed at the position where the
3 is opened across the hard wall portion of the cabinet body 1 from the lower sloped surface of the side projecting portion 1a of the cabinet body 1. Reference numeral 14 denotes a door fixed to the rotating shaft 2 so that the window 13 is closed when the tumbler 10 is in the return position shown in FIG. 1, and opened when the tumbler 10 is in the reverse position shown in FIG. It has a bent shape along the portion 13, and its upper side has a shallow hopper shape. Further, a support frame 15 is provided on the door 14 so as to face toward the inside of the cabinet body 1, and a product supply chute 16 is provided on the upper side of the support frame 15, and a product discharge chute 17 is provided on the lower side of the support frame 15. Each is provided approximately in the axial direction of the tumbler 10, and both are provided in the direction of the axis of the tumbler 10.
The size is such that it can be stored inside. The supply chute 16 has its tip facing the opening 11 of the tumbler 10 and has a closed hopper shape on the other side, and the discharge chute 17 is made of a perforated member such as punching metal or wire mesh. is in contact with the outside of the opening 11, and 18
Reference numeral 1 denotes a nozzle for spraying a projectile material which is movable in the upper part of the cabinet body 1, 19 is an inspection window, and 20 is a hopper which is movably disposed outside the cabinet body 1.

With this structure, first, the piston rod 7 of the cylinder 6 is in the state shown in FIG.
With the tumbler 10 raised and the tumbler 10 in the inverted position, the product is introduced into the supply chute 16 from the movable hopper 20 holding a predetermined amount of product. Next, the cylinder 6 is actuated to lower the piston rod 7 by a predetermined amount, and the swinging arm 4 is swung clockwise to rotate its axis. Rotate by a predetermined amount. As a result, the door 14, the supply chute 16, and the discharge chute 17 also rotate in the same direction about the rotation axis 2, and the door 14 as shown in FIG.
is pressed against the window part 13 to seal the window part 13, and the supply chute 16 and the discharge chute 17 are held in a semi-inverted state with their tips facing diagonally downward within the sealed cabinet body 1. Ru. Further, at the same time as the rotation of the rotation shaft 2, the rotation frame 8
also rotates in the same direction, and the tumbler 10 held by it is stopped at the return position with its opening 11 diagonally upward. Then, while the supply chute 16 rotates and becomes semi-inverted, the supply chute 1
The product put into the opening 11 rotates in the same way.
flows diagonally upward into the tumbler 10.
Thereafter, the nozzle 18 is moved by a moving mechanism (not shown).
is made to face into the tumbler 10 from the opening 11,
The blasting material is projected toward the group of products rolling in the tumbler 10, which rotates by the operation of the drive device, thereby performing cleaning. When the cleaning is finished, the nozzle 18 is opened at the opening 1 by a timer or other means.
As the cylinder 6 moves back from the 1 side, the piston rod 7 rises again, rotating the swinging arm 4 until it reaches the position shown in Fig. 2, which causes the rotation shaft 2 to rotate counterclockwise. As a result, the tumbler 10 is rotated via the rotation frame 8 to an inverted position with the opening 11 diagonally downward as shown in FIG. As a result of this rotation, the supply chute 16 and the discharge chute 17 as well as their distal ends are positioned to the outside of the cabinet body 1. Due to the rotation, the processed product in the tumbler 10 falls from the opening 11 onto the discharge chute 17 due to its own weight, and is automatically discharged to a predetermined location, where it sticks to the product or falls as the product rolls and falls. The shot material is separated while falling on the discharge chute 17 and falls out through the hole or mesh portion, and is opened to the shallow hopper-shaped door 14.
It will be collected inside and will not be scattered outside. During this time, the next predetermined amount of product is dropped from the moving hopper 20 onto the supply chute 16, and the above operation is repeated.
Continuously automated operation. Note that the above-mentioned operation can of course be performed manually, and the rotation of the rotation shaft 2 can also be electrically operated by a motor or the like.
Further, the tumbler 10 may be rotated as necessary when discharging the product.

(Effect of the invention) As is clear from the above description, the present invention has a structure in which the product supply chute, discharge chute, and door rotate together with the tumbler. The window part of the tumbler is opened or sealed by the door, and at the same time, the product in the tumbler is discharged to the discharge chute or the product is charged from the supply chute, allowing automatic continuous operation, and each chute is integrated. This eliminates product scattering and residue during product supply and discharge, and there are fewer seals required, eliminating the need for projectile material to fly out. Moreover, the drive parts for the tumbler, door, supply chute, and discharge chute are all located in one place. It has a compact structure and can be manufactured at low cost.
