Then, the barrel moving motor 7 that moves the tilted barrel structure 6 up and down in a swinging manner, and the abrasive material projection that projects the abrasive material disposed on the left and right sides of the barrel 2 with the barrel 2 positioned below. A machine 8 is provided. 9 is a screw conveyor that collects and transports the abrasive that has fallen below the barrel 2, and 10 receives the abrasive that is conveyed by the screw conveyor 9, and conveys it upward to be supplied to the abrasive projector 8 again. Thus, the elevator is stored in the polishing material tank 11 located above the barrel 2.

The barrel 2 has a shape close to a Soroban ball with a truncated cone-shaped bottom surface. As shown in FIG. 1, the barrel 2 projects a polishing material or puts in and out the object to be polished in the center of opposite side surfaces. For the purpose of cleaning, an opening 2a is provided, and the whole is formed of a porous material in order to screen out the polishing material projected into the barrel 2.
The barrel 2 is configured to be rotationally driven using an outer periphery that does not interfere with the operations so as to perform the operations of insertion, projection, and ejection from the central opening 2a on both side surfaces. That is, the barrel 2 is rotatable at the four corners of the support frame 3 so as to rotate at the time of projection and idling without positioning an actual rotation mechanism in the opening 2a while being centered on an axis passing through the opening 2a. Four rollers that are pivotally supported and rotationally driven in contact with the barrel 2 are arranged. A chain member is looped around the rollers, and a sprocket 12 for rotationally driving the chain member can be engaged and disengaged. The structure is provided in Further, the rotation driving means of the barrel is not limited to the driving means using the sprocket and the chain of the present embodiment, and other appropriate driving means such as a V belt, a pulley, and a gear may be used.

  In FIG. 1 and FIG. 2, an inclined barrel structure 6 including a barrel 2 (including the support frame 3) connected to the barrel support shaft 4 and a barrel inclination motor 5 is driven by a barrel moving motor 7. Thus, two vertical positions rotating in a swinging manner are shown, and in FIG. 1, the swinging angle is about 30 degrees. The barrel 2 is loaded with an object to be polished as shown by an arrow in FIG. 2 at an upper position away from the abrasive material projector 8, and is set at a projection position of the abrasive material projector 8 at a lower position. While being engaged with the sprocket 11 and rotating, the object to be polished is cleaned and idled. In the above-described embodiment, the insertion position of the barrel 2 has been described as a position rotated about 30 degrees above the projection position. However, the present invention is not limited to this, and the barrel 2 is positioned away from the projection position. As long as the object to be studied can be charged (including discharge), it may be at an appropriate angle of less than 30 degrees or 30 degrees or more, and may be at the lower side instead of the upper side.

Abrasive material is projected toward the object to be polished through 2a. Thus, the object to be polished in the barrel 2 is projected with the abrasive from both the left and right sides while rolling together with the barrel 2, so that the entire surface is efficiently and evenly cleaned in a short time.

  Next, when the scouring is completed, projection of the scouring material by the scouring material projector 8 is stopped, and the scouring material remaining inside the barrel 2 that continues to rotate is screened downward. Thereafter, the sprocket 12 is stopped and detached from the chain member around the barrel 2. Then, as shown in FIGS. 1 and 2, the barrel tilting motor 5 tilts the barrel 2 about 90 degrees about the axis, and either one of the opening portions 2a of the barrel 2 faces downward so that the inside of the barrel 2 extends from the opening portion 2a. A series of work is completed by discharging the object to be studied. Then, in order to process the next object to be studied, the barrel 2 is returned to the vertical position, lifted to the upper position, and the work cycle from the introduction of the object to be studied is started again.
