Description

[Detailed Description of the Invention] The present invention relates to an improvement of a compression device that moves a press die toward a compression seat and compresses a workpiece on the compression seat.

Conventionally, the material to be processed that has been compressed in the compression device is discharged outside the compression device, and then the worker manually puts it into a storage container or the like. If radioactive materials or dust that is harmful to the human body were attached to the equipment, there was a risk that workers would be exposed to radiation or suffer from respiratory diseases.

This proposal addresses the above-mentioned problem, and includes a compression device that moves a pusher die toward a compression seat to compress the workpiece on the compression seat. A movable support rod for the clamping arm penetrating in a direction perpendicular to the moving direction, a plurality of clamping arms for the workpiece fixed to the outer end of each support rod, and each clamping arm via each support rod. and a drive device for a clamping arm provided in the press die to move the compressed material to a clamping position, the purpose of which is to move the compressed workpiece to a storage container or the like. It can be automatically stored without scattering harmful substances such as dust. Another object of the present invention is to provide an improved compression device that can not only make the entire compression device more compact but also reduce equipment costs.

Next, the compression device of the present invention will be explained with reference to an embodiment shown in FIGS. 1, 2, and 3. In FIG.
is a drum (storage container), E is a workpiece, and a press die B is lowered by a cylinder A to compress the workpiece E on a compression seat C. Next, the press die B will be specifically explained with reference to FIGS. 2 and 3. 1 is the body of the press mold B, 2 is the lower surface compression part, 1a
are vertically elongated recesses provided at multiple locations on the outer peripheral surface of the body portion 1, 3 is a vertical rotating shaft provided on the lower surface compression portion 2, and 4 is the inner space of the press mold B;
A parent bevel gear 5 is provided at the parent bevel gear 5, and child bevel gears 6 of the same number as the number of clamping arms 9 are meshed with the parent bevel gear 5, and a spline shaft 7 passes through each child bevel gear 6. Further, the spline shaft 7 passing through each child bevel gear 6 passes through the press mold body 1 and has a support rod 8 at its outer end that is integrated with each clamping arm 9. The rod 8 moves forward and backward in the outward and outward directions, and the clamping arm 9 engages with a camshaft 11 that moves in and out of the recess 1a provided in the wall surface of the body of the press mold 1. 12a is also engaged. The rotating disk 12 is a piston rod 13 of a drive device (cylinder) 13.
By transmitting the movement of a through the crankshaft 14, the rotating disk 1 rotates around the rotating shaft 3.
The camshaft 11 engaged with the guide hole 12a provided in 2 is tilted, and the tilting of the camshaft 11 advances and retreats the support rod 8 in the inward and outward directions of the press mold B, so that the outer end of the support rod 8 The fixed clamping arm 9 is opened and closed. On the other hand, the rotating shaft 3 to which the parent bevel gear 5 mentioned above is fixed has a rotating shaft turning arm 15, with which a rotating shaft turning moving piece 16 is engaged. 18 is the body part 1 of the parent bevel gear drive device press mold B.
Parent bevel gear drive mounted on the inner wall, 19a,
19b is a pulley attached to both ends of the drive device 18; 17a and 17b are cables with one end attached to the movable piece 16;
The other ends of a and 17b are connected to the pulleys 19a and 19b.
The cable 1 is attached to the piston rod (not shown) of the drive device 18 through the cable 1 when the piston rod is moved in one direction or the other.
Either one of 7a and 17b is pulled, and the rotating shaft 3 and the main bevel gear 5 are rotated in one direction or the other direction via the arm 15 of the moving piece 16. The child bevel gear 6 meshed with the parent bevel gear 5 is rotated by the rotation of the parent bevel gear 5, rotates the spline shaft 7 passing through the child bevel gear 6, and is fixed to the outer end of the spline shaft 7 (support rod 8). The clamping arm 9 is then rotated clockwise and counterclockwise.

Next, the operation of the compression device will be explained. () After the object to be compressed E is compressed by the push die B, the push die B is raised by the lifting cylinder A of the push die B. () A drive device 13 moves a plurality of clamping arms 9 which are housed in the concave portion 1a of the outer wall surface of the body of the pusher die B and form a part of the outer wall surface of the body of the pusher die B.
By the operation of , it is made to protrude (open) from the body of the pusher die B. () Since the protruding clamping arm 9 has the clamping part 9a located above, the drive device 18 is operated to rotate the rotary shaft 3 and the main bevel gear 5 fixed thereto. The main bevel gear 5 and the child bevel gear 6 meshing with it are set at a gear ratio of 3:1, and when the main bevel gear 5 is rotated by 60 degrees, the child bevel gear 6 is rotated by 180 degrees. The interlocking clamping arm 9 is rotated by 180 degrees so that the clamping portion 9a is positioned downward. ()
With the clamping arm 9 protruding (opened) and the clamping part 9a facing downward, the presser die raising/lowering cylinder A is operated to lower the presser die B, and the workpiece is moved between the plurality of clamping arms. Make sure to surround it with 9. ()
Operating the drive device 13 in the opposite direction to the above (),
The clamping arms 9 are retracted (closed), and the workpiece immediately below the lower surface of the push die B is clamped by the plurality of clamping arms 9. () After the press die B holding the object to be processed is slightly raised, the compression seat C disposed at the top of the drum D is removed from above the drum, and the top of the drum D is opened. () The workpiece held by the holding arms 9 provided on the push die B is inserted into the drum D by lowering the push die lifting cylinder A and stopped at a predetermined position.
() The clamping arm 9 is protruded in the manner described in () above, and the workpiece E is thrown into the drum can D without any clamping force on the workpiece. ()
The press mold B that has been completely loaded is raised to a predetermined position, and then the clamping arm 9 is housed in the body recess 1a of the press mold B according to the steps () and () above.

The compression device of the present invention is constructed as described above, and when the compressed material is stored in a storage container such as a drum D, it can be automatically stored without scattering harmful substances such as dust. In addition, the internal space of the pressing die B used for compression is utilized,
A drive device for the clamping arms is provided, which has the effect of making the entire compression device more compact and reducing equipment costs compared to a case in which separate equipment is provided for storing the material in drums or the like.
