Description

  The present invention relates to a stacking adapter for stacking roll products equipped with a roll product protector, and more specifically, a conventional roll product protector that is not provided with unevenness for stacking is mounted. Even if it is a case, it is related with the adapter for stacking which can stack a roll product efficiently.

Conventionally, when transporting and storing strip-shaped products such as plastic film and paper, as shown in FIG. 5, these strip-shaped products R1 are wound around a core material R2 to form a roll product R, which is then transported and stored. In order to prevent the surroundings of the roll product R from becoming dirty or damaged, a roll product protector (hereinafter sometimes simply referred to as a protector) P is assembled to the roll product R for transportation and storage.
This conventional protector P is formed by inserting a hat-shaped support shaft P2 made of synthetic resin into a shaft hole provided near the center of a side plate P1 made of square plywood or synthetic resin. Both end surfaces are sandwiched between a pair of side plates P1, and a hat-type support shaft P2 is inserted into a hollow hole of the core member R2 to support the roll product R. Further, when storing the roll product R with the protector P mounted thereon, as shown in FIG. 6, the roll product R is mounted on another roll product R at the upper edge of the protector P mounted on the roll product R. The protector P was placed and stacked.

  However, in the conventional protector P, since the edge of the side plate P1 is flat, if the protector P mounted on another roll product R is placed thereon, as shown in FIG. When an impact is applied to the roll product due to bounce, a deviation occurs between the upper and lower protectors P, and the upper protector P may slide off from the edge of the lower protector P. There are problems such as the peripheral surface being damaged and the product value being significantly reduced.

  In order to solve such a problem, for example, as shown in Patent Document 1, rolls stacked on the upper side by using the protectors provided with unevenness at the edge and engaging the unevenness of these protectors. It has been proposed to prevent the product from falling. However, a protector provided with such engagement irregularities cannot be used with a conventional protector without irregularities. Therefore, it is necessary to discard all the conventional protectors and replace them with bumpy protectors, but it is not only extremely uneconomical to dispose of the conventional protectors, but the conventional protectors are already used in large quantities. Therefore, a great deal of cost and labor are required for replacement.

The present invention is an adapter for stacking roll products equipped with a roll product protector, and as shown in FIG. 1, a substrate portion 2 having substantially the same shape as the end surface of the roll product protector P, and a substrate portion It has the upper fitting part 3 standingly arranged from the periphery of 2, and the lower fitting part 4 suspended from the periphery of the board | substrate part 2. It is characterized by the above-mentioned.
The stacking adapter 1 of the present invention is used as a pair, and is interposed between protectors P attached to the stacked roll products R as shown in FIG. That is, by inserting the end edges of the stacked protectors P into the upper fitting portion 3 and the lower fitting portion 4 of the adapter 1 and fitting the adapter 1 to the edge of the protector P, the protector P By connecting them together, the roll product R is prevented from collapsing.
In addition, the upper side and the lower side of the fitting portion in the present invention only indicate directions in the adapter 1, and for example, the adapter 1 can be used upside down to stack the roll products R. .

  The material of the stacking adapter 1 of the present invention is not particularly limited, and examples thereof include metal, wood, paper, and resin. Resin is preferable because it is easy to mold and is lightweight. For example, ABS resin ( Acrylonitrile-butadiene-styrene copolymer resin), AAS resin (acrylonitrile / acrylic rubber / styrene resin), AES resin (acrylonitrile / ethylene propylene rubber / styrene resin), AS resin (acrylonitrile / styrene resin), PS resin (polystyrene resin) , PMMA resin (polymethyl methacrylate resin), PVC resin (polyvinylidene chloride resin), MS resin (methyl methacrylate / styrene resin), PP resin (polypropylene resin), PE resin (polyethylene resin), PBT resin (polybutylene terephthalate resin) ) And PC Fat (polycarbonate resin) and the like. Biodegradable plastics such as polylactic acid, polybutylene succinate, polyamide 11, polyhydroxybutyric acid, and biomass plastics can also be used.

In the present invention, the board portion 2 is a plate-like member whose outer shape is substantially the same shape as the end face of the protector P, and partitions the interior of the adapter 1 of the present invention with one fitting portion (for example, the upper fitting portion 3) and the other. The fitting part (for example, the lower fitting part 4) is partitioned.
The substrate part 2 is not limited as long as the outer shape is substantially the same shape as the end face of the protector P, and may have a shape without holes as in the first embodiment shown in FIG. 1, or the second embodiment shown in FIG. The through-hole 5 having a size that prevents the protector P from passing therethrough may be provided. By providing such a through hole 5, material saving and weight reduction of the adapter 1 can be achieved.
Since the end face of the protector P is often a long rectangle having an aspect ratio of 1:10 or more, the shape of the substrate portion 2 is often a long rectangle according to this. What is necessary is just to determine suitably a specific magnitude | size according to the magnitude | size of the protector P to be used.

In the present invention, the upper fitting portion 3 is made of a wall-like member standing from the periphery of the substrate portion 2, and the lower fitting portion 4 is made of a wall-like member hanging from the periphery of the substrate portion 2. At the time of use of the present invention, the end portion of the protector P is inserted and fitted into a portion surrounded by the wall-like member in the upper fitting portion 3 and the lower fitting portion 4, and thereby the protector P stacked vertically. Are connected to prevent the collapse of the stacked roll products R.
The upper fitting portion 3 and the lower fitting portion 4 are not limited as long as the shape surrounds the end of the protector P, and a wall-like member having no hole as in the first embodiment shown in FIG. The wall may be formed with a through hole 5 that does not cause the adapter to become excessively weak as in the second embodiment shown in FIG. 3 to save material and reduce the weight. it can.

The size of the upper fitting portion 3 and the lower fitting portion 4 is appropriately determined according to the size of the edge of the protector P. The degree of adhesion when the edge of the protector P is inserted is not particularly limited, and both the upper fitting part 3 and the lower fitting part 4 may be loosely fitted together, or both may be tightly fitted, The other may be tightly fitted. When one is loosely fitted and the other is tightly fitted, the upper fitting portion 3 is tightly fitted to the edge of the protector P, and the lower fitting portion 4 is loosely fitted to the edge of the protector P. It is preferable to design. In this way, the protector P connected by the adapter 1 of the present invention can be separated with almost no resistance, so that it is very easy to separate and lift the stacked roll products. Furthermore, since the adapter 1 remains fitted to the protector P inserted into the upper fitting portion 3 even after being separated, there is no risk of losing it.
In addition, as a method of close fitting, the dimension of an upper side and a lower side fitting part shall be a dimension which can be tightly fitted, and a protrusion etc. are provided inside an upper side and a lower side fitting part.

When the upper fitting part 3 is dimensioned to be tightly fitted to the edge of the protector P, as shown in Example 3 of FIG. 4, it is preferable to expand the upper end part inside of the upper fitting part 3 in a tapered shape. preferable. If it does in this way, since the edge of protector P can be inserted along the taper-shaped expansion part 6, it will become easy to insert in the upper fitting part 3, and workability | operativity which fits the adapter 1 to the protector P becomes easy. Enhanced. Of course, if necessary, the lower fitting portion 4 can also have a tapered widened portion on the inner side of the upper end portion.
Moreover, in order to increase the frictional force between the upper fitting portion 3 and the protector P so that the adapter 1 is not easily detached from the protector P, the upper fitting portion 3 is larger than the lower fitting portion 4. preferable. In that case, the upper fitting part 3 may come into contact with the roll product R and damage the strip-like product R1, so that the upper part of the upper fitting part 3 is centered around the through hole of the protector P as shown in FIG. It is preferable to prevent the roll product R and the upper fitting portion 3 from coming into contact with each other. Of course, if necessary, the lower fitting portion 4 can be similarly cut out in an arc shape.

In the above, the stacking adapter of the present invention has been described as a single unit, but if necessary, a plurality of roll products with protectors can be stacked at the same time by connecting a plurality of them in the horizontal direction. is there.
Further, the protector P is not limited to the illustrated one. For example, a protector having a shape in which the side plate P1 and the hat-type support shaft P2 are integrated may be used.

  As described above, the stacking adapter of the present invention can prevent collapse of the load even when an impact is applied to the stacked roll products, and can be used with a conventional protector. It can greatly enhance the safety and efficiency of storage and transportation, and is extremely useful.
