点検が大変である。 By the way, in air filter disassembly equipment that filters air containing dust contaminated with radioactivity, a cylinder device is used as a drive source, and the disassembly and other processing members are operated by the expansion and contraction movement of the piston rod. There is a risk that contaminated dust adhering to the piston rod will mix with the working fluid of the cylinder device and come out of the processing chamber as the piston rod reciprocates. In order to prevent this, it is possible to cover the piston rod with a retractable bellows.
Since the bellows itself is not a so-called durable material but a consumable item, it cannot be said to be a fundamental solution, and maintenance and inspection are difficult.

Place it on 5,25. Further, the end surface of the wooden frame 2 of the air filter 1 is brought into contact with the receiving surface 20 of the receiving member 15. After the air filter 1 is supported in this way, the push-out member 11 is moved to the left in the figure by the operation of the hydraulic cylinder device 7. Then, the filter material 3 of the air filter 1 is released from the adhesive state with the wooden frame 2 by the extrusion force of the extrusion member 11, passes through the extrusion hole 16 of the receiving member 15, and is discharged from the discharge hole 36 formed on the upper surface of the base 4. It falls downward, passes through the discharge duct 37, and is stored in a storage section (not shown) provided outside the base 4.

ない。 Next, the second step will be explained based on FIGS. 8a, b, and c. The second step is a step of dividing the wooden frame 2 from which the filter material 3 was separated in the first step described above into four plate materials 2b. That is, the supporting members 21, 21
are moved inward until they hit the inner stoppers 28b, 28b to minimize the distance between them. Then, the wooden frame 2 is placed on these supporting members 21, 21 in a laid down state. Specifically, two opposing sides of the wooden frame 2 are inserted between the inner clamping piece 24b and the outer clamping piece 24a of each support member 21, and the lower end thereof is placed on the second mounting section 26. Further, one side of the wooden frame 2 is brought into contact with the receiving surface 20 of the receiving member 15. Then, the pressing member 11 is moved to the left by the operation of the hydraulic cylinder device 7, and the wooden frame 2 is strongly pressed. As a result, one side of the wooden frame 2 is cut using the cutters 12 provided on both sides of the pressing member 11.
At this time, the wooden frame 2 is placed at a high position because it is placed on the second mounting part 26, and the necessary cutting line of the wooden frame 2 is thereby placed within the range of the cutters 12, 12 on both sides of the extrusion member 11. be able to. Further, during this cutting, the wooden frame 2 may be bent due to the pressing force of the extrusion member 11, and buckling may occur particularly at both sides. However, the support members 21 are attached to both sides of the wooden frame 2.
Since the wooden frame 2 is held between the holding pieces 24a and 24b, problems such as bending and buckling of the wooden frame 2 do not occur.

That is, after the second step is completed, the wooden frame 2 is pulled out from the supporting members 21, 21, turned 180 degrees, and is again supported by the supporting members 21, 21 in the same manner as the second step. Then, the other sides of the wooden frame 2 are cut using the cutters 12, 12 on both sides of the extrusion member 11. In this way, the wooden frame 2 is divided into four plates 2b....

保守が容易となる。 As explained above, the processing apparatus of the present invention has a support member attached to the partition wall of the processing chamber which is equipped with a means for receiving radioactive contaminants inside and is isolated from the outside world.
A cylindrical body is supported by this support member so as to be movable in the axial direction, with one end placed in the processing chamber and the other end taken out of the processing chamber, and one end of the cylindrical body in the processing chamber are connected to each other, and a cylinder body is fixed within the cylindrical body, and the outer end of the piston rod of the cylinder body is connected to a support piece provided outside the processing chamber, so that the cylinder body is fixed to the piston rod outside the glove box. The structure is such that the robot moves and performs work inside the glove box, and after the contaminated dust generated inside the glove box is prevented from leaking outside between the support member and the cylinder, only a small amount of contaminated dust is removed. Since the piston rod reaches the piston rod and is further prevented from entering the working fluid of the cylinder device between the cylinder and the piston rod, the degree of contamination of the working fluid and related equipment such as the hydraulic unit is significantly reduced, which makes maintenance easier. becomes easier.
