The shot blasting device 63 configured as described above opens the opening 5 by opening the opening/closing R6 of the upper processing chamber 3 of the case body 1.

After that, the rotation device 8 is activated.

That is, the induction motor 19 is driven and the rotation shaft 15 is rotated via the spiral gear 17.16.

Since the casing 20 similarly rotates due to the rotation of the rotation shaft 15, the basket attachment rotatably attached to the casing 20 causes the basket 7 attached to the plate 32 to also rotate, and the opening 5 opens the case from the opening 5. It rotates so as to protrude to an outside position of the body 1.

When storing the deburred molded product 10 in the basket 7, the rotation device 8 is stopped at a position where the opening of the basket 7 has an inclination angle of approximately 45°, and the deburred molded product 10 is stored in the basket 7. Store it.

After that, the rotating device 9, the high pressure blower 57, and the sorting device 3
6. While operating the projection material supply device 50, the upper processing chamber 3 is filled with inert gas using the inert gas supply device W60.

By filling the upper processing chamber 3 with inert gas, the inert gas is transferred to the upper processing chamber 3, the lower processing chamber 4, and the sorting device 3.
6, the blasting material supply device 50, and the blast pipe 54, all of which are filled with an inert gas atmosphere.

In addition, the motor 2 with a brake is rotated by the operation of the rotating device 9.
The driving force of 6 is transmitted to the rotating shaft 22 via the bevel gears 24 and 23, and to the shaft 31 to which the basket mounting plate 32 is fixed via the bevel gears 28 and 33, and the basket 7 rotates. The molded product stored in the stirring blade 13.13.
13. Stir with 13 etc.

Furthermore, by the operation of the high-pressure blower 57, air is blown at high pressure from the nozzle 56 toward the molded product 10 in the basket 7. At this time, the high-pressure air passing through the nozzle 56 causes the shot material 38 in the shot material storage tank 49 to is suctioned through the blasting material supply pipe 58, and is injected with the high-pressure air included therein.

Therefore, the shot material 38 sprayed from the nozzle 56 collides with the burrs of the molded product 10 and removes the burrs.

When the burrs are removed from the molded product 10 after operating for a predetermined period of time, the rotating device 9 and the high-pressure blower 57 are stopped, the opening/closing door 6 is opened, and the rotating device 18 is operated to completely close the opening of the basket 7. By rotating downward from the horizontal state, the molded product 10 from which burrs have been removed in the basket 7 is chipped or automatically dropped to the outside where it can be received by a tray or the like.

[Different Embodiments of the Present Invention] Next, different embodiments of the present invention shown in FIGS. 9 and 10 will be described. In explaining this embodiment, the same components as those in the embodiment of the present invention are given the same reference numerals and redundant explanation will be omitted.

The embodiment shown in FIGS. 9 and 10 is mainly different from the embodiment of the present invention described above in that an impeller type projecting material projection device 53A is installed in the upper processing chamber 3. Similar effects can be obtained with the shot blasting device 63A.
