Description

  The present invention relates to a packing body for a hose, particularly a simple packing body for an industrial hose having a diameter of 19 mm or more, a packing method, and a packing jig.

  Traditionally, industrial hose packaging has a hose end fixed to a rotary disk, and the spine is wound in multiple stages while turning the disk to form a donut-shaped hose roll, with a rope from the center to the outermost part at 3 to 8 locations. In general, as a main package for preventing contamination during transportation and storage after tying and fixing, the belt-shaped wrapping paper is gait-wrapped from the center to the outermost part. However, the above-mentioned prior art is a double effort that overlaps completely in terms of the function of fixing the shape such as temporary fixing and main packing at the hose production site, and unwinding at the hose usage site. It takes time to unpack, and it is difficult to reuse the packing material after use.

  The present invention eliminates the drawbacks of the prior art described above, and can reduce the packing effort at the hose production site, the unpacking effort at the hose usage site, and the reuse of the packaging material after use. It is an object to provide a packing body, a packing method, and a packing jig.

The above object is achieved by closely attaching a hose winding body having rebound resilience to the inside of the packing cylindrical sheet, and by drawing the strings provided on the circumferences of the upper and lower ends of the cylindrical sheet. This is achieved by providing a hose package that is packed in the cylindrical sheet.
Further, the above object has a guide in the circumferential direction on the rotating disk, deploys a cylindrical sheet for packing in the guide, and winds a hose having rebound resilience by rotating the disk into the cylindrical sheet, This is achieved by providing a method for packing a hose roll, in which the hose roll is brought into close contact with the inside of the cylindrical sheet, and the strings provided on the circumferences of the upper and lower ends of the cylindrical sheet are drawn.
In addition, the object is to have a guide for developing a cylindrical sheet for packing in a circumferential direction on the rotating disk, to wind a hose having rebound resilience by rotating the disk into the cylindrical sheet, This is achieved by providing a packing jig for tightly attaching to the inside of the sheet.

  INDUSTRIAL APPLICABILITY The present invention is useful for reducing the packaging effort at the hose production site, the unpacking effort at the hose usage site, and reusing the packaging material after use.

Next, the present invention will be described with reference to the drawings.

FIG. 2 is a perspective view showing the hose winding body 3 in which the hose 2 is wound in a donut shape.
FIG. 3 is a perspective conceptual view of a packing body in which the hose roll 3 is brought into close contact with the inside of the packing cylindrical sheet 4.
FIG. 4 is a perspective view including a partial cross section showing a use state of the packing jig 9 having the rotating disk 10 and the guide 11 provided on the circumference of the rotating disk 10 and the cylindrical sheet 4 developed on the guide 11 when the hose is caught. FIG.

The present invention will be described with reference to FIGS.
The hose package 1 shown in FIG. 1 has a high resilience and a large hose outer diameter in the state where the hose 2 shown in FIG. Although it is suitable for packaging, it is particularly suitable for packaging of industrial hose rolls having functionality such as a hose containing reinforcing fibers having an inner diameter of 19 mm or more and a hose containing a hard spiral core having an inner diameter of 19 mm or more.

  The material of the cylindrical sheet 4 in FIG. 3 is not particularly limited, and may be any flexible resin sheet, laminate sheet, or inflation resin film, but a polypropylene cross sheet is optimal from the viewpoint of hose protection strength. is there. Further, as a cylindrical processing method of the cylindrical sheet 4, two long sides of the rectangular sheet are folded back and stitched or welded to provide stitched portions 5, 5 ′ (the passages of the upper and lower drawstrings 7, 7). A method is preferable in which two short sides of the sheet are overlapped, and the overlapped portion is stitched or welded except for the stitched portions 5 and 5 ′ to form the stitched portion 6 to form a cylindrical body. When using various resin-made inflation films as the material of the cylindrical sheet 4, there is a slight problem in terms of protection strength because no fiber material is used, but it does not require a cylindrical stitching cost. May be preferred. In this case, a polypropylene blown film having a thickness of 50 to 500 microns is preferable.

  The cylindrical sheet 4 has a structure in which the drawn cords 7 and 7 ′ are passed through the upper and lower cord openings 8 and 8 ′, and the drawn cords 7 and 7 ′ are partially or entirely built. Here, as a part of the squeezed cords 7 and 7 ′, straps or eyelets are provided at intervals of 5 to 50 cm in the upper and lower circumferential directions of the cylindrical sheet, and squeezed cords are provided there. It is done.

Next, a more detailed hose winding method of the present invention and a packing jig used therein will be described with reference to FIG.
FIG. 4 shows a packing jig 9 having a guide 11 on the circumference of the rotating disk 10, and the cylindrical sheet lower end 12 is narrowed down in advance and arranged at the center of the rotating disk, and the cylindrical sheet upper end 13 is placed outside the guide. Indicates the folded state. By rotating the rotating disk on the support column 14, the hose 2 can be wound into the cylindrical sheet 4, and the hose roll 3 can be packed by drawing the strings 7 and 7 '.

  The guide 11 on the rotating disk 10 is provided on the entire circumference or at several places on the circumference, and examples of the shape thereof include a plate shape, a rod shape, and a pipe. In particular, a plate-shaped guide having a width corresponding to 5 to 60 degrees and a height equal to or higher than the hose winding height, which is bent according to a desired outer diameter curvature, is preferable. It is preferable that more than one location is provided because it is easy to take out the cylindrical sheet after packing.

  The hose 2 is rolled into the cylindrical sheet 4 for packing arranged in advance on the rotating disk 10, and is wound into a donut-shaped hose winding body closely attached to the inside of the cylindrical sheet 4. By returning the upper end 13 of the cylindrical sheet 13 and drawing the drawn cords 7 and 7 ', a hose package is obtained.
