TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cargo collapse prevention net used with a pallet for transporting cargo (hereinafter, referred to as a “pallet”).
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in order to prevent the collapse of a box-shaped luggage stacked on a trolley, a pallet, or the like, a method of winding and fixing a disposable plastic tape multiple times around the stacked luggage has been generally used.
[0003]
FIG. 3 is a diagram illustrating a state of use of a conventional example of a load collapse prevention device that is not disposable but is used repeatedly. In order to prevent the stacked cargo 200 from collapsing, a strip-shaped cargo collapse prevention device 100 is used. The load collapse prevention device 100 is wound around the stacked cargo 200 and fixed with a hook-and-loop fastener or the like provided on the locking portions 102 at both ends (see Patent Documents 1 to 4).
[0004]
Further, a load collapse prevention network as disclosed in Patent Document 5 has been proposed. The load collapse prevention net disclosed in Patent Document 5 includes a tubular net member having a cross-sectional area equal to or larger than the pallet bed area, a band member passing along the opening edge of the tube and the outer periphery of the tube, and And a plurality of hook portions provided at the lower end. The baggage is covered with the tubular net member, the band member is pulled to tighten the opening, and the hook portion is fixed by hooking on the pallet.

However, when a disposable plastic tape is used, a large amount of dust is generated, which is not preferable from the viewpoint of environment and resource saving. In addition, when the belt-shaped members described in Patent Literatures 1 to 4 are used, it is not easy to perform the operation of winding the belt-shaped members around the stacked cargo alone. Further, when a plurality of band-shaped members are required to cover the whole, the work load is further increased.
[0007]
The tubular net member described in Patent Document 5 has a size having a cross-sectional area equal to or larger than the pallet's bed area, and is adapted to the size of the pallet or the load by tightening the band member. Practically, the luggage is fixed only by the band member, and the net member itself is in a loose state. Therefore, the entire stacked cargo cannot be fixed with an equal holding force. Further, since the hook mounting position is fixed, the hook cannot be mounted if the hooking position on the pallet side does not match the hook mounting position. That is, it cannot be applied to pallets of various shapes.
[0008]
In view of the above situation, the present invention is a cargo collapse prevention net used with a pallet, which can stably fix the entire stacked cargo with an equal holding force, is easy to attach, and has a pallet and a cargo. It is an object of the present invention to provide a cargo collapse prevention net that can flexibly adapt to changes in the shape and size of the cargo.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, a load collapse prevention net according to the present invention has a tubular net portion formed of an elastic material, and an elastic net passed along each of an upper edge and a lower edge of the tubular net portion. And a wire rod.
Preferably, a pair of upper closures that can be connected to each other are provided at opposing positions on the upper edge of the tubular net portion.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a load collapse prevention net 10 according to the present invention. The load collapsing prevention net 10 has a tubular net portion 11 formed of an elastic material, and elastic wires 14 and 16 pass along the entire upper and lower edges of the tubular net portion 11 over the entire circumference. Have been. Naturally, the illustrated shape is not fixed, and the overall shape of the load collapse prevention net 10 is freely deformable (including elastic deformation). Therefore, it is possible to flexibly respond to a change in the size of the pallet or the load. The tubular net portion 11 is manufactured by, for example, winding a flat elastic net material into a tubular shape and fixing the elastic net material at the connecting portion 18. As the material of the tubular net portion 11 and the elastic wires 14 and 16, any elastic fiber having appropriate elasticity and durability can be used, and examples thereof include polyurethane and aromatic polyamide. As another example, rubber may be used.
[0011]
Preferably, a pair of upper closures 12a and 12b that can be connected to each other are provided at opposing positions of the upper edge of the tubular net portion 11 (positions that form about 180 degrees in the case of a circumference). The pair of upper closures 12a and 12b are, for example, easily detachable like a hook-and-loop fastener shown in the figure. Alternatively, hooks and buttons that engage with each other may be used.
[0012]
FIG. 2 is a use state diagram in which the load collapse prevention net 10 according to the present invention of FIG. With reference to FIG. 2, the process of attaching the load collapse prevention net 10 will be described. First, the cargo collapse prevention net 10 is put on the load 20 stacked on the pallet 30 to cover the load 20. Preferably, the size of the load collapse prevention net 10 is set so that the load collapse prevention net 10 covers the entire stacked cargo 20 in a state of being slightly elastically stretched. That is, it is sufficient to set the entire length around the cylinder of the load collapse prevention net 10 to be shorter than the entire length around the cross section of the pallet. With this setting, the elasticity of the load collapsing prevention net 10 is evenly applied to the entire stacked load, and the entire load can be stably held.
[0013]
After the entire luggage is covered by the load collapse prevention net 10, the four corners of the upper edge elastic wire 14 are hooked on the four pallet columns 34, respectively. Next, the lower edge elastic wire 16 is hooked on each of the four mounting brackets 36 provided so as to project downward from the four lower corners of the pallet base 32. Finally, the upper surface of the stacked cargo 20 is fixed by connecting the pair of upper closures 12a and 12b to each other.
[0014]
【The invention's effect】
The load collapse prevention net according to the present invention is configured to have a tubular net portion formed of an elastic material, and an elastic wire rod passed along each of an upper edge and a lower edge of the tubular net portion. Thereby, since it can be deformed including elastic deformation, it is possible to flexibly adapt to changes in the size of the pallet and the load, and the elasticity thereof can stably fix the entire stacked load with a uniform holding force. In addition, when the upper closure of the collapse prevention net is provided, the stacked cargo can be held more stably.
[0015]
In addition, the elastic wires at the upper edge and the lower edge are hooked on the pallet column and the under-hanger, so that the displacement and prevention of the collapse prevention net can be prevented. Furthermore, since the elastic wires at the upper edge and the lower edge are passed through the entire circumference, even when used for various pallets where the positions of the pallet pillars and the platform hanging tools are different, regardless of the hooking position, the elastic wires are used. Can be hooked.
[0016]
Furthermore, the work of putting the cargo collapse prevention net on the loads stacked on the pallet, hooking the elastic wire, and closing the upper closure can be performed very easily by one person.
