Description

[Detailed description of the invention] [Field of industrial application] The present invention is aimed at improving the stacking position of cardboard cases when the cardboard cases containing film-wound products supported and fixed on reinforcing plates are stacked and transported. This invention relates to a stacked reinforcing plug that is used by being fitted into a reinforcing plate in order to prevent scratches caused by the reinforcing plate of a film-wound product due to misalignment.

[Prior art and its problems]

When transporting cardboard cases in which film-wound products are supported and fixed on reinforcing plates, they are stacked and transported.
There is a problem in that the reinforcing plate in the upper cardboard case buckles the lower cardboard case due to the shift in the stacking position of the cardboard cases, and comes into contact with the film product, causing scratches on the surface of the film product. As a measure to prevent the occurrence of scratches, attempts have been made to attach a contact plate to each corner of the reinforcing plate. However, when attaching the backing plate to each corner, manual processing such as nailing and attaching is required, which poses a problem of high cost.

[Purpose of this invention]

The purpose of this invention is to prevent the reinforcing plate of the upper cardboard case from shifting when the cardboard cases in which the film-wound product is supported and fixed on the reinforcing plate are stacked in multiple tiers and transported. To provide a reinforcing plug for stacking that is attached to a reinforcing plate in order to prevent a lower corrugated cardboard case from being crushed and to prevent scratches from occurring on a film product.

[Structure of the present invention]

The object of the present invention described above is to provide a load receiving part, an end wall part hanging from one end of the load receiving part, a middle wall part hanging from an arbitrary lower end of the load receiving part, and a connection between the load receiving part and the middle wall part. This can be achieved by a stacking reinforcing plug in which the reinforcing ribs are integrally molded, and the frame plate insertion part is formed by the end wall part and the middle wall part.

The reinforcing plug for stacking according to the present invention will be explained below with reference to the drawings. Figure 1 shows a front view of an example of the reinforcing plug for stacking according to the present invention, and Figure 2 shows a perspective view of Figure 1. In the figure, 1 is a load receiver, and 2 is a part hanging from one end of the load receiver. 3 is a middle wall part that hangs down from an arbitrary lower part of the load receiving part, 4 is a reinforcing rib that connects the load receiving part and the middle wall part, and 5 is a frame composed of the end wall part and the middle wall part. The plate (reinforcing plate) insertion portion 6 is a crimp convex portion. Materials constituting such reinforcing plugs for stacking include ABS resin, hard PVC resin, PP resin, etc., but are not particularly limited to these. In addition, each part of the reinforcing plug for stacking, that is, the area and thickness of the load receiving part, end wall part, middle wall part, reinforcing rib, width l of the frame plate insertion part, etc., is determined by the weight of the film wound product, the frame plate ( It can be determined as appropriate depending on the size, shape, etc. of the reinforcing plate. The reinforcing plug for stacking can be obtained by molding using an injection molding machine or an extrusion molding machine.

3A, B and 4 show examples of how the reinforcing plug for stacking according to the present invention is used. FIG. Fig. 3A shows a front view of the stacking reinforcing plug 11 according to the present invention, and Fig. 3B shows a state in which the reinforcing plug 11 for stacking according to the present invention is fitted through its frame plate (reinforcing plate) insertion part.
is its side view. Figure 4 shows the fixing holes 13 of the frame plates 12, 12 into which the reinforcing plugs 11 for stacking are fitted,
13 is a side cross-sectional view showing a state in which a film-wound product 15 is supported and fixed in a cardboard case 14 and the cardboard cases are stacked in two tiers, and the stacking positions are shifted. FIG. As another preferred embodiment of the reinforcing plug for stacking according to the present invention, as shown in the perspective view of FIG.
It is possible to install a stopper plate 7 inside to prevent the reinforcing plug from slipping inward, thereby improving the stability of the load receiving part 1. In addition, a nail hole 8 is provided narrowly in the load receiving part 1 to prevent the reinforcing plug from slipping inside. It is also possible to fix the reinforcing plug and reinforcing plate by hammering.

[Effect]

When transporting cardboard cases in a stacked state, even if the stacking position of the upper cardboard case shifts as shown in FIG. Since the receiving parts 1 support the reinforcing plate 12, the reinforcing plate 12 of the upper cardboard case does not crush the lower cardboard case, and the occurrence of scratches on the film product stored in the lower cardboard case can be prevented. .

〔effect〕

Since the reinforcing plug for stacking according to the present invention has the above-described configuration, it can exhibit the following effects.

(1) When transporting cardboard cases in which film-wound products are supported and fixed on reinforcing plates and stored in multiple tiers, the reinforcing plug for tiering according to the present invention can be inserted into the reinforcing plates. Even if a shift in the stacking position of the cardboard case occurs, it is possible to eliminate the occurrence of scratches on the film product inside the cardboard case due to the shift.

(2) The reinforcing plug for stacking according to the present invention has a reinforcing rib that supports the load receiver, and can exhibit its effect without any problem even if an excessive load is applied to the load receiver.

(3) The reinforcing plug for stacking according to the present invention can be provided with a crimping protrusion at the lower end of the end wall and the lower end of the middle wall, so that the reinforcing plug can be attached to the reinforcing plate when it is fitted into the reinforcing plate. can be easily supported.
