Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for compressing bulky objects to reduce their volume.

Generally, when inserting a large item into a small space (space), methods such as disassembling it to fit the dimensions of the small space or molding it using a compression device are taken, but the disassembly work for this purpose is This requires a large amount of manpower or special equipment, which wastes time, money, and installation space.

For example, when compressing and reducing the volume of frame filters used in nuclear power plants, etc., a mold as shown in Figure 1 is used to shape the large frame filter 03 into a shape that can be stored in a drum can or the like with a smaller diameter than the filter. Shape. In this case as well, the preforming molds 02a and 02b are used to form the frame filter 03 so as to fit inside the molds 01a and 01b for molding it into a circular shape.
A method is adopted to narrow the width of the area. (Otherwise, the dimensions of the molds 01a, 01b would become considerably large, and special molds would be required for each large and small filter 03.)However, the preforming molds 02a, 02b and their driving devices require space; This compressor requires a large installation space. Further, if the preforming mold 02a or 02b is not used, a part of the frame of the framework filter 03 gets caught in the meeting portion of the molds 01a and 01b, making it impossible to obtain a satisfactory compressed shape.

The present invention was made in view of the above-mentioned circumstances, and provides a frame filter consisting of a frame assembled into a substantially rectangular shape and a transparent member stretched in the frame.
It is an object of the present invention to provide a compact compression volume reduction device capable of compressing while preventing the framework from being jammed.

Hereinafter, the present invention will be explained based on illustrated embodiments. Fig. 2 is a perspective view showing the entire embodiment of the present invention, and Fig. 4 is a plan view showing the main parts of the embodiment. , a main body 4 in which a substantially semicircular bayous portion 3 is formed, and guide portions 5 that protrude substantially in parallel from the protruding ends at both ends of the bayous portion 3. The guide section 5 is
It has a substantially plate-like shape, and a sliding guide groove, which will be described later, is cut inside the plate.

A mold 11 is fitted inside the tip of the guide portion 5 of the mold 1. The mold 11 has a main body 8 in which a curved portion 7 having a similar shape opposite to the curved portion 3 is formed. A reciprocating drive device, that is, a hydraulic cylinder 13 is connected to.

The hydraulic pump, control valve, tank, hydraulic piping, etc. connected to the hydraulic cylinder 13 are not shown because they are well known to those skilled in the art.

FIG. 3 is an enlarged perspective view showing details of the guide section 5. FIG. In FIG. 3, a guide groove 15 cut parallel to the inner surface of the guide portion 5 is aligned and connected to a guide hole 16 provided through the main body 4. As shown in FIG. As shown in FIG. 2, the guide portions of the mold 11, that is, the guide rods 18, are slidably fitted into the guide grooves 15 that have been cut in five grooves, and the tips thereof are connected to the guide holes 16. They protrude from the outer end of the mold 1 through them, and are further connected to each other by beams 19.

Furthermore, in the mold 1, the bay part 3 and the guide part 5
A fork portion 21 that is inclined in a horizontal plane is formed between them, and a similar fork portion 23 is also formed in the mold 11 between the bay-shaped portion 7 and the guide rod 18.

In this embodiment having the above-described configuration, the process of compressing the frame filter 100 having the substantially square frame 101 will be explained with reference to FIGS. 5A to 5D.

(a) Open the molding molds 1 and 11 to the left and right, and insert the frame filter 100 into the space for receiving the compressed object between them.

(b) Hydraulic cylinder 13 connected to molding die 11
Push the molding die 11 in the direction of the arrow. As a result, the slopes of the fork portions 21 and 23 push the frame filter 100 into the molding molds 1 and 11.

(c) When the molding die 11 is further pushed in, the fork part 2
1 and 23 and the curved parts 3 and 7 of the molding dies 1 and 11, the frame filter 100 is deformed and approaches the desired shape. At this time, since the framework 101 of the framework filter 100 is pushed in by the fork parts 21 and 23, it is not sandwiched between the left and right molds 1 and 11.

(d) Push the molding die 11 further and fork part 2
1 and 23 are fitted into each other, the molds 1 and 11 completely form the desired shape, and the large frame filter 100 is compression molded into a small capacity.

As mentioned above, the molds 1 and 11 facing each other
The fork part 2 located outside the bay parts 3 and 7 of
1 and 23 push the framework 101 of the framework filter 100 inward, so that the framework filter 100 can be compressed to a small size without being caught between the molds 1 and 11.

In the above embodiment, an example was explained in which the substantially square frame filter 100 was compressed, but it is possible to compress and reduce the volume of objects of other shapes by adjusting the horizontal inclination angles of the fork parts 21 and 23. Of course.
