る。(Structure of the invention) Hereinafter, the structure of the invention will be described in detail based on drawings of embodiments. A cabinet 1 constitutes a cleaning room, and shot projectors 2 and 3 are disposed at the ceiling and bottom of the cabinet 1, respectively. Between the side walls of the middle stage of the cabinet 1, a large number of rollers 4, 4 are arranged in the left-right direction and are rotatably arranged.
are mounted on bearing units 6, 6 fixed to the outer surface of the cabinet 1 via brackets 5, 5. Further, the rollers 4, 4 are connected to a motor with a reduction gear (not shown) via appropriate transmission means. The rollers 4, 4 in that area are spaced apart from each other by a required distance so that the shot projected from the shot projector 3 provided at the bottom of the cabinet 1 does not hit directly (see FIG. 3). Also,
Of the rollers 4, 4 arranged in an open manner, a rotating shaft 7, which is parallel to and faces the roller 4, is located directly above the roller 4 on the product loading side, as shown in FIG. The rotating shaft 7 is connected to the roller 4 via gear pinions 9 and 10.
Further, a cylindrical presser roller 11 having an appropriate length and an inner diameter larger than the outer diameter of the rotating shaft 7 is mounted around the center of the rotating shaft 7, and the presser roller 11 is attached to a bracket. A stopper 13 fixed to the inner surface of the cabinet 1 via 12, 12,
13 for positioning. Note that 14 is a screw shaft of the screw conveyor.

シヨツトが順次衝突して表裏両面が研掃される。(Operation of the device) Next, the operation of the device configured as described above will be explained. The shot projectors 2 and 3 are driven to project the shot toward the rollers 4 and 4, and a motor with a speed reducer (not shown) is driven to rotate the rollers 4 and 4 counterclockwise. When the product to be polished is fed onto the rollers 4 and 4 under this condition, the product is transferred over the rollers 4 and 4 in the direction of the arrow, and eventually the tip of the product is between the presser roller 11 and the roller 4. reach. When the product reaches between the presser roller 11 and the roller 4, the inner surface of the presser roller 11 is in contact with the outer surface of the rotating shaft 7, and the rotating shaft 7 is transmitted with the rotation of the roller 4 via the pinion gears 9 and 10. Since the presser roller 11 is rotated clockwise by the presser roller 11, the product is placed on the product at the same time.
The product enters between rollers 1 and 4, and is then transported in the direction of the arrow. As a result, the product is transferred while being pressed downward by the presser roller 11, and the shots projected from the shot projectors 2 and 3 successively collide with each other to polish both the front and back surfaces.

的効果を奏する。(Effect of the invention) As is clear from the above explanation, the present invention has a cabinet 1 equipped with a shot projector 3 at the bottom.
A large number of rollers 4, 4 are arranged horizontally in a middle position, are supported on their axis, and are rotatable, and of the rollers 4, 4, the rollers 4, 4 near the shot projection area of the shot projection machine 3 are arranged on the product loading side. A rotary shaft 7 is rotatably supported directly above the roller 4 at an appropriate distance from the roller 4 and parallel to and facing the roller 4, and one end of the rotary shaft 7 is connected to the roller 4. and the rotating shaft 7 via a transmission means.
Since a cylindrical presser roller 11 is mounted on the holder, the product is pressed downward by the presser roller 11 when polishing is performed by projecting a shot from below while transferring the product via the rollers 4, 4. Therefore, unlike conventional devices of this type, the collision of the shot can cause the product to float up, resulting in uneven polishing, products to overlap each other, or products to warp in the direction of shot projection. It has excellent practical effects such as no oxidation.
