DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding and packing method for transporting a long tube.

[0002]

2. Description of the Related Art For example, a flexible long tube continuously formed by extrusion or the like, such as a sheath for optical cables, is wound spirally a predetermined number of times. Generally, they are loaded on a transport vehicle such as a truck and transported from a factory to a construction site or the like.

[0003] When the long tube is transported, the long tube is bound and packed before being transported, and the long tube bundled and packed by a crane or the like is suspended and moved as described below. Loaded on trucks and other transport vehicles. In a conventional binding package, first, as shown in FIG. 8A, a long tube P is spirally wound by a known winding device or the like a predetermined number of times, and then, as shown in FIG.
As shown in (1), the wound long tube P is bound by a binding member 60 made of a string or the like at a predetermined position (in the illustrated example, six places having substantially equal intervals). After that, as shown in FIG.
Packing by wrapping (film wrapping)
Subsequently, as shown in (D) of the figure, hanging jigs 70 are attached to predetermined positions of the long tube P (three positions having substantially equal intervals in the illustrated example).

The hanging jig 70 will be described in detail. The jig 70 comprises a belt member having insertion holes 71 and 72 at both ends. And, this hanging jig 70
Is attached to the wound long tube P by suspending the hanging jig 70 around the center side inner surface, lower surface, outer surface, and upper surface of the long tube P wound and bundled. This is achieved by inserting one end of the base 70 into the insertion hole 71 on the other end.

The long tube P packed and packed as described above is
A hook portion such as a crane is hooked into the insertion hole 72 on the free end side of the hanging jig 70 and is suspended and moved, thereby being loaded on a transport vehicle such as a truck. When the transport vehicle arrives at the construction site, the long pipe P on the vehicle is attached to the hanging jig 7 as in the case of loading.
A hook portion such as a crane is hooked on the insertion hole 72 on the free end side of No. 0 and is unloaded from the transport vehicle.

However, the conventional hanging jig 7
In the case where the long pipe P is hung and movably bundled using 0, the work of attaching and detaching the hanging jig 70 to and from the long pipe takes time, resulting in poor workability. . In addition, since the hanging jig 70 is made of a somewhat hard material and has a certain thickness, the hanging jig 70 is used to transport the long tube P packed and packed by a transport vehicle. When the long tube (rolled material) P is left standing in the attached state, particularly when a plurality of the long tubes P are left standing, the length of the long tube P is reduced due to its own weight or the like. There is a possibility that deformation such as a dent may occur at the portion where the hanging jig 70 of the long tube P is attached. Therefore, the hanging jig 70 must be removed from the long pipe P when transporting by the transport vehicle, that is, the mounting of the hanging jig 70 at the time of loading and unloading the long pipe P on the transport vehicle.・
Removal work was required for each, which was extremely complicated. Further, when the hanging jig 70 is used, the binding member 60 and the hanging jig 70 need to be separately prepared, which is not advantageous in terms of cost.
