Description

  The present invention relates to a roll product protector for transporting and storing a roll product in which a long object such as a film is wound around a core material. More specifically, the roll product protector is inserted into the core material of a roll product equipped with the protector. Only the roll product is lifted by the shaft and can be carried to a cutting machine, a printing machine, etc., and can be set on these parts, and insects, dust, etc. can enter from the shaft conduit provided in the protector to pass the shaft. It is related with the protector for roll products which can be prevented.

  Conventionally, when protecting, transporting, and storing long objects such as plastic films, plastic sheets, paper, etc., roll these long objects around a core material to form a roll product. In order to prevent the peripheral surface from being stained or damaged, a so-called protector is mounted on both sides of the end surface of the roll product, and then stored and transported and stored in a case.

  In the case of a large and heavy roll product, a lifting means such as a crane is used to store and remove the roll product from the storage case and to attach the roll product to a processing machine such as a cutting machine or a printing machine. .

For example, a roll product packaging method has been proposed in which a protrusion is provided on a support plate, a hanging tool is fixed to the protrusion, and the roll product is lifted and accommodated in an exterior material (see Patent Document 1).
Further, a container has been proposed in which a shaft core receiving portion having a guide groove supports and stores both ends of the shaft core protruding from the roll product (see Patent Document 2).

However, in the packaging method of Patent Document 1, since the roll product is lifted together with the support plate, that is, the protector, there is no problem as a packaging method. However, when the product is used, the protector is removed and only the roll product is cut or printed. It is unsuitable when set in a machine, and it is necessary to remove the protector separately. However, in the case of a large and heavy roll product, it is not easy to remove the protector.
Moreover, in the container of the said patent document 2, since the both ends of the shaft core which protruded from the roll product are supported and accommodated in a shaft core receiving part, the roll product which does not have the shaft core which protruded from the roll product (shaft core) It cannot be applied to a roll product in which the end portion and the end face of the roll product are flush with each other.
In view of such circumstances, the present invention eliminates the problems of the prior art described above, eliminates the need to remove the protector from the roll product in advance, and removes only the roll product with the protector attached to the roll product from the shaft guide provided in the protector. An object of the present invention is to provide a roll product protector that can be lifted and that can prevent dust, insects, and the like from entering from the shaft guide of the protector during transportation and storage of the roll product.

The present invention has been made to achieve the above object, and the feature of the present invention is a roll product protector mounted on the end surface to protect the end surface of the roll product. a core receiving the projecting is fitted into the core of the roll product from part has a shaft insertion recesses formed inside the core material receiving, for internal shaft insertion before SL core receiving A roll product protector having a shaft guide that is cut from the recess so as to expand in a tapered shape toward the edge of the substrate portion, and provided with a shutter that closes the shaft guide . Except that only a part of the shaft guide is closed) .

  Another feature of the present invention is the above-described protector for roll products, wherein the shutter is provided by sliding the inner surface of the shaft guide path.

  Still another feature of the present invention is the above-described protector for roll products, wherein the shutter is provided at the edge of the shaft guide via a hinge portion.

The protector for roll products of the present invention has a shaft path for lifting only the roll product through the shaft while the roll product is protected by the protector, and a shutter for closing the shaft path. It is easy to carry the roll product to a cutting machine, printing machine, etc., and set it on them. Also, during transport and storage of the roll product, insects and dust from the protector shaft guide It is possible to prevent the commercial value of the roll product from being reduced due to intrusion of the like.
As a structure of the shutter, a structure in which the inner surface of the shaft guide is slid or a structure in which the shutter is provided at the edge of the shaft guide via a hinge portion is preferable.

FIG. 8 is a schematic cross-sectional view showing a state in which a roll product is lifted via a shaft guide path.

  The protector for roll products of the present invention is attached to the end surface to protect the end surface of the roll product. As shown in FIGS. 1 to 4, the protector for the roll product protrudes from the substrate portion 2. The core material receiver 3 fitted into the core material C of the roll product P, and the shaft guide 4 cut into the core material receiver 3 from the edge of the substrate portion 2, and the shaft A shutter 5 for closing the guide path 4 is provided. 4 d is a shaft insertion recess formed in the lower part of the shaft guide path 4 and in the core material receiver 3.

As shown in FIGS. 1 and 2, the roll product protector 1 of the present invention includes a substrate portion 2 and a core material receiver 3, and a shaft guide path 4 is cut.
The substrate portion 2 and the core material receiver 3 according to the present invention protect the roll product of the type in which the end portion of the core material does not protrude from the end surface except that a part thereof is notched by the shaft guide path 4. It is the same as the general protector used to do. Explaining a typical example in the present invention, the substrate portion 2 is a plate-like body having a substantially polygonal shape (in the illustrated example, a quadrangular shape) except for a notch of the shaft guide path 4 to be described later. By pressing the flat surface against the end face of the roll product, the long object wound around the core material is prevented from being deformed into a bamboo shoot shape, and the end face is prevented from being damaged by contact with foreign objects. .

The core material receiver 3 in the present invention is a portion that protrudes from the substrate portion 2 and is fitted to the core material C of the roll product R as shown in FIG. The position of the core material receiver 3 is not particularly limited as long as it can be fitted to the core material C of the roll product R, but is usually provided at the center on the inner surface side of the substrate portion 2. The shape of the core material receiver 3 is not particularly limited as long as the shape can be fitted to the core material C of the roll product R. Usually, the outer diameter is substantially the same as or slightly larger than the inner diameter of the core material C, which will be described later. Except for the shaft insertion recess 4d formed in the lower portion of the shaft guide path 4, the projection is a substantially cylindrical short protrusion.
As shown in the figure, a rib for reinforcing the core material receiver 3 may be provided on the inner side or the outer side of the core material receiver 3 (inner side in FIG. 3), or it can be easily inserted into the core material. Thus, the tip end side may be formed in a rounded shape or a tapered shape.

The shaft guide 4 in the present invention is for lifting the roll product on the shaft S in a state where the protector 1 is mounted on the roll product without removing the protector 1 from the roll product in advance. More specifically, as shown in the use state of FIG. 3, the shaft guide path 4 is cut into the core material receiver 3, and the lower shaft insertion recess 4 d enters the core material receiver 3. . Therefore, the roll product R is inserted into the shaft insertion recess 4 d below the shaft guide path 4 with the protector 1 being mounted. Further, since the shaft guide path 4 is cut from the edge of the substrate portion 2 to the inside of the core material receiver 3, and a lower shaft insertion recess 4d is formed, the roll product R is inserted into the shaft insertion recess 4d. In a state where S is inserted, it is lifted by a crane or the like (not shown) via the shaft guide path 4, and is carried and set by a cutting machine or a printing machine.
The shape of the shaft guide path 4 is not particularly limited as long as the shaft S can be guided upward from the edge of the substrate portion 2 to the inside of the core material receiver 3, but a shape cut into a U shape is preferable. Also, as in the example shown in FIGS. 1 to 4, it is preferable to make the entrance S side U-shaped with a tapered shape because the roll product R can be easily lifted via the shaft guide path 4.

The roll product protector 1 of the present invention is provided with a shutter 5 for closing the shaft guide 4 when the roll product is transported or stored with the protector attached.
The structure of the shutter 5 is not particularly limited, and any structure can be adopted as long as the shaft guide 4 can be closed. However, in the example shown in FIGS. 1 to 4, the shutter 5 is more than the shaft guide 4. It has a slightly larger shape and is about one third of the thickness of the substrate portion 2, and a groove 4 a is provided on the inner surface of the shaft guide path 4 so that the shutter 5 can slide. The shaft guide path 4 is closed by inserting the shutter 5 from the end edge toward the core material receiver 3 side. It is also possible to provide a groove on the side surface of the shutter 5 and provide a line-like projection that fits in the groove on the inner side surface of the shaft guide path 4.
Further, as shown in FIG. 5, a convex portion 4b is provided on the inner surface of the shaft guide path 4, the shutter 5 is pushed into this portion, the shutter is elastically deformed to get over the convex portion 4b, and fitted. You can also.
Furthermore, as shown in FIG. 6, the board | substrate part 2 and the shutter 5 can be connected via the hinge part 4c, and it can also be set as the structure which can be opened and closed by a hinged door shape. If necessary, the shutter 5 may be opened and closed in a double-speech manner that opens on both sides.

The material for the protector for roll products of the present invention is not particularly limited, but a resin is preferable in that it is easy to process 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 (polychlorinated) Used are vinylidene 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). Possible it is. 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.
