The end face protecting plate 2 is formed of a flat plate portion 3, a bearing portion 4 raised from the flat plate portion 3 toward the interior, and a fitting portion 5 into which the peripheral surface protecting cylinder 7 is fitted.

Description

  The present invention relates to a roll product protector for transporting and storing a roll product formed by winding a long article such as a film around a core, and more specifically, protecting not only the end face of the roll product but also the peripheral surface. The present invention relates to a protector for roll products, which can protect various types of roll products having different lengths with a small number of members, and thus has a low cost.

Conventionally, when transporting and storing long objects such as plastic films, plastic sheets, paper, etc., these long objects are wound around a core body to form a roll product, and the end surface and peripheral surface of the long object In order to prevent soiling and damage of the roll product, bearing members and the like are mounted on both sides of the end face of the roll product, and then transported and stored in a case (see Patent Document 1).
However, since roll products have various lengths, it is necessary to prepare various types of cases in order to handle various types of roll products, and the cost for that case increases, which increases the cost. There is.

In order to solve this problem, it is composed of two holder pieces in which a wall portion is erected on the periphery of the plate-like part, and the other holder piece is inserted into one of the holder pieces in a nested manner. A configured roll-shaped object holder has been proposed (see Patent Document 2).
This roll-shaped material holder can be used for a plurality of roll-shaped materials having different lengths by adjusting the overlapping width of the wall portions to be fitted, so that the cost for molds and inventory management can be greatly reduced. It is excellent. However, since it has a structure that adjusts the overlapping width of the wall portions that are inserted and fitted in a nested manner, the length of the longest roll-like material and the shortest roll-like material that can be accommodated in one holder is 2 times the width of the wall portion. Since it is necessary to manufacture a holding tool having a large wall width in order to accommodate a roll-like object having a length of only twice or more, the cost reduction is limited.

FIG. 6 is a back view of the end face protection plate showing still another example of the fitting portion. FIG. 7 is a plan view of the protector for roll products of the present invention. FIG. 8 is an explanatory view showing an engaged state of ribs when the protectors for roll products of the present invention are stacked.

  The roll product protector of the present invention is for storing and protecting a roll product made of a long product wound around a core, and as shown in FIG. 1 to FIG. The end surface protection plate 2 includes a flat surface portion 3, a bearing portion 4 erected on the inner surface side from the flat plate portion 3, and a fitting portion 5 for fitting the peripheral surface protection tube 7. It is characterized by comprising.

As shown in FIGS. 2 to 4, the end face protection plate 2 in the present invention is fitted to hold a bearing portion 4 for holding the core body 8 of the roll product R and a peripheral face protection cylinder 7 described later. A plate-like member having a part 5. The end face protection plate 2 has its flat plate portion 3 pressed against the end face of the roll product R, so that the long object wound around the core body 8 slides out and the shape of the roll product R is deformed into a bamboo child shape. As well as preventing the end surface from being damaged by contact of foreign matter.
The shape of the flat plate portion 3 is not particularly limited, but if the shape has at least one straight side, the protector for roll products does not roll carelessly by placing the straight side down and handling it. It is preferable because it is easy to store and manage. Examples of the shape having at least one straight side include a regular polygon shape and a rectangular shape (in the example shown in FIGS. 1 to 4, a square shape). Moreover, a curve may be sufficient about the part except a linear side like a half-moon shape.

From the flat plate portion 3 of the end surface protection plate 2, a bearing portion 4 is erected toward the inner surface side of the end surface protection plate 2 (the direction of the surface that becomes the inner side of the protector for roll products). Although the position of the bearing part 4 will not be specifically limited if it is a position which can be fitted to the core of the roll product R, Usually, it is provided in the inner surface side center part of the end surface protection plate 2. The shape of the bearing part is not particularly limited as long as it is a shape that can be fitted to the core of the roll product, but usually, a cylindrical short protrusion having an outer diameter that is substantially the same as or slightly larger than the inner diameter of the core. Is done.
A rib for reinforcing the bearing portion 4 may be provided inside or outside the bearing portion 4, or the tip side may be formed in a round shape or a taper shape so as to be easily inserted into the core body. Also good. In addition, when a rib is provided in the outer side of the bearing part 4, the said rib has a function which prevents that the mounted end surface protection board 2 rotates around a core body as well as reinforcement.

The end surface protection plate 2 is provided with a fitting portion 5 for fitting the peripheral surface protection cylinder 7. The position of the fitting portion 5 is not particularly limited, but if the edge portion of the end surface protection plate 2 protrudes greatly from the outer edge of the peripheral surface protection tube 7, the end surface is caused by the impact of the edge portion of the protruded end surface protection plate 2 colliding with foreign matter. Since there is a possibility that the protection plate 2 may come off, it is preferable that the fitting portion 5 is provided in the vicinity of the edge portion of the end face protection plate 2 so that the edge portion does not protrude greatly.
The structure of the fitting part 5 is not particularly limited as long as the peripheral surface protection cylinder 7 can be fitted, but as shown in FIGS. 3 and 4, the peripheral wall part 5 a erected from the peripheral edge of the flat plate part 3, and the peripheral wall part It is preferable that the peripheral surface protection cylinder 7 is sandwiched between the peripheral wall portion 5a and the inner wall portion 5b. In this case, for example, as shown in FIG. 2, the gap between the peripheral wall portion 5a and the inner wall portion 5b is set to be substantially the same as or slightly smaller than the thickness of the peripheral surface protection cylinder 7, and the inner side of the inner wall portion 5b from the gap entrance If the peripheral surface protection cylinder 7 is press-fitted into the gap as a taper shape narrowing toward the end, it is preferable because the end surface protection plate 2 and the peripheral surface protection cylinder 7 are easily fitted and are not easily removed.
As another structure of the fitting portion 5, as shown in FIG. 5, a plurality (four in FIG. 5) of outer wall portions 5c are provided around the inner surface of the outer wall portion 5c. A structure to be fitted and a structure in which a plurality of (four in FIG. 6) inner wall portions 5b are provided as shown in FIG. 6 and the peripheral surface protection cylinder 7 is fitted outside the inner wall portion 5b can be exemplified. . Also in this case, the same effect as described above can be obtained if the entrance side is tapered. It is also possible to engage the projections and depressions so that the end surface protection plate 2 and the peripheral surface protection cylinder 7 are not inadvertently detached. In this case, the uneven engagement can be easily released by bending using the flexibility of the peripheral surface protection cylinder 7. Further, when the peripheral surface protection cylinder 7 is made of plastic corrugated cardboard, although not shown, comb-like projections that can be inserted into the air holes between adjacent ribs may be provided.

  The protector 1 of the present invention has a structure in which a peripheral surface protection cylinder 7 is provided between two end surface protection plates 2, and even if a force is applied from the outer surface side of the end surface protection plate 2, the force is applied to the peripheral surface. Since it is absorbed by the protective cylinder 7, the force is not transmitted to the inside roll product. Therefore, unlike the conventional protector, even if the protector 1 is placed vertically so that the end face protection plate 2 is up and down, and another protector is loaded on the protector 1, the roll product R accommodated in the upper protector 1 is placed. Is supported by the peripheral surface protection cylinder 7 of the lower protector 1, so that the protector 1 can be loaded without damaging the roll product R in the lower protector 1. Of course, if necessary, they can be stacked horizontally.

  The shape of the outer surface side of the end face protection plate 2 (the direction of the surface not in contact with the roll product) is not particularly limited, and the same shape and structure as those used in ordinary protectors are the end face protection plate 2 of the present invention. Can also be used. Specifically, ribs for reinforcing the flat plate portion are often provided on the outer surface side of this type of protector. However, as shown in FIG. it can.

  As described above, the protector 1 of the present invention can be stacked with the end face protection plate 2 placed vertically so that the end face protection plate 2 is vertically positioned. Therefore, when such stacking is planned, the end face protection of the stacked upper and lower protectors is performed. The rib 6 on the outer surface of the plate 2 can be engaged to function as a slip stopper. For example, in the example shown in FIG. 7, the rib 6 has a substantially square shape and is composed of four types, a slightly larger one and a smaller one, and a slanted one-line and two-line one. As shown in FIG. 8, as shown in FIG. 8, a small substantially square rib 6 is inserted into a large approximately square rib 6, and a single line diagonal rib is included in the double line diagonal rib 6. 6 is inserted and engaged, and functions as a slip stopper.

The material of the end face protection plate 2 is not particularly limited, but a resin is preferable because it is lightweight and easy to mold. 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 resin (polycarbonate resin) can be used. Furthermore, biodegradable plastics such as polylactic acid resin, polybutylene succinate, polyamide 11, polyhydroxybutyric acid, biomass plastics, and the like can also be used. When biodegradable plastics are used, the use of fossil resources is reduced. In particular, biomass plastics are made of plant-derived materials, so only CO ₂ fixed by plants is emitted even after incineration. Carbon neutral with no increase in CO ₂ emissions is achieved, and it has the advantage of contributing to the prevention of global warming in an environmentally friendly manner.

In this invention, it is comprised so that the surrounding surface of the accommodated roll product may be covered with the surrounding surface protection cylinder 7 by attaching the surrounding surface protection cylinder 7 to said fitting part 5. FIG. Although the shape and structure of the peripheral surface protection cylinder 7 are not particularly limited as long as the peripheral surface of the roll product to be accommodated can be protected, a cross-sectional shape may be a polygonal cylinder such as a circle or a regular square.
The relationship with the planar shape of the end surface protection plate 2 is not particularly limited, and the planar shape of the end surface protection plate 2 and the cross-sectional shape of the peripheral surface protection cylinder 7 may be different (shown in FIGS. 5 and 6). In this example, the planar shape of the end surface protection plate 2 is a square, whereas the cross-sectional shape of the peripheral surface protection tube 7 is an octagon), and if different, the edge of the end surface protection plate 2 is the outer edge of the peripheral surface protection tube 7. Since the end face protection plate 2 may come off due to the impact of the edge of the protruded end face protection plate 2 colliding with a foreign object, the peripheral surface should not be protruded greatly. The cross-sectional shape of the protective cylinder 7 is preferably substantially the same as the planar shape of the end face protective plate 2.

  Since the shape of the peripheral surface protection cylinder 7 of the present invention can be a simple cylinder, it can be manufactured very easily and inexpensively. Moreover, since the peripheral surface protection cylinder 7 for protecting a roll product with a short length can be easily obtained by cutting the long peripheral surface protection cylinder 7 according to the length of the roll product, it is short separately. It is not necessary to prepare the peripheral surface protection cylinder 7 in advance. Accordingly, roll products having different lengths can be stored and protected by one type of peripheral surface protection cylinder 7, so that the manufacturing cost is greatly reduced and inventory management is easy.

The material of the peripheral surface protection cylinder 7 is not particularly limited, and any resin that can be used for the end surface protection plate 2 can be suitably used. Further, when not used, it is preferable to make the peripheral surface protection cylinder 7 foldable because transportation and storage are facilitated. For example, a commercially available plastic corrugated cardboard can be rolled into a cylindrical shape and used as the peripheral surface protection cylinder 7. When the plastic cardboard is rolled up to form the peripheral surface protection cylinder 7, it can be made into a sheet shape that is the original shape when not in use, so there is little space for storage, and since it is flexible, it can be folded. Can be stored.
Moreover, if the surrounding surface protection cylinder 7 is made transparent or semi-transparent, the presence / absence, contents, state, etc. of the roll product can be confirmed from the outside of the protector 1, so that the handleability is improved.

  As described above, the roll product protector according to the present invention includes an end face protection plate and a peripheral surface protection cylinder. Therefore, not only the end face of the roll product but also the peripheral surface can be protected. Further, by cutting the peripheral surface protection cylinder in accordance with the length of the roll product, it is possible to house and protect various types of roll products having different lengths, and therefore, a significant cost reduction is possible.
