Description

  The present invention relates to a roll product protector for transporting and storing a roll product obtained by winding a belt-shaped product around a core material. More specifically, the present invention relates to a roll product protector that has a simple structure and is light in weight, and is bulky when not in use. It is related with the protector for roll products which can be piled up compactly without.

Conventionally, when transporting and storing strip products such as plastic films, plastic sheets, paper, etc., as shown in FIG. 14, these strip products R1 are wound around a core material R2 to form a roll product R, In order to prevent the periphery of the roll product R from becoming dirty or damaged during transportation and storage, the roll product R is assembled with a roll product protector (hereinafter sometimes referred to simply as a protector) P, and is transported and stored. It was.
This conventional protector P is formed by inserting a hat-shaped support shaft P2 made of synthetic resin into a shaft hole provided in the vicinity of the center of a rectangular plywood side plate P1, and both ends of the roll product R are connected to a pair of side plates P1. And supporting the roll product R by inserting the headed support shaft P2 into the hollow hole of the core material R2, and if necessary, wrapping the packing band B outside the side plates P1 in a cross shape. Tightened.

  However, according to the above-mentioned conventional protector P, the work of assembling the protector P to the roll product R is complicated, and the plywood of the side plate P1 is poor in durability, so that the side plate P1 is easily damaged. This protector touches or collides with the peripheral surface of the adjacent roll product R when the stacking position is shifted during transportation and storage. In some cases, the peripheral surface of the strip-shaped product R1 is contaminated or damaged, and the value of the product is significantly reduced.

  In order to solve such a problem, a protector that protects the peripheral surface of a roll product by using a protector having legs and supporting the protector with the legs even if the stacking position is slightly shifted has been proposed. Yes. As such a protector for roll products, for example, a rectangular substrate portion that presses an end surface of the roll product on the inner surface, and a central projection on the inner surface of the substrate portion that can be inserted into a hollow hole of the hollow core portion of the roll product. A rolled product supporting cylindrical portion, a stacking leg projecting from the inner square of the substrate portion, and a stacking recess provided in the surface square of the substrate portion so that the tip of the leg portion can be inserted. It is a hard synthetic resin molded body comprising: each side length of the substrate portion is longer than the outer diameter of the roll product, and the leg length of the leg portion is longer than the total length of the cylindrical portion. There is a protector for roll products that is characterized (see Patent Document 1).

Utility Model Registration No. 2604907 (FIGS. 3, 4, and 5)

However, in the conventional roll product protector provided with the leg, the stacking leg is composed of a protruding stacking leg and a stacking recess into which the tip of the leg can be inserted, Since these leg lengths are configured to be longer than the entire length of the roll product supporting cylindrical portion, not only the structure is complicated and the weight is increased, but also, for example, as shown in FIG. When this protector is stacked and stored during use, this leg becomes an obstacle, and even if stacked, it does not become compact below the leg length of the leg. In addition, there is a disadvantage that a vast space is required for storage.
In view of such circumstances, the present invention is an improvement of the conventional protector, which is simple in structure and light in weight, and can be stacked compactly without being bulky even when stacked when not in use. The purpose is to provide a protector for roll products that does not require a vast space for storage and has improved transport efficiency and storage efficiency.

The invention according to claim 1 of the present invention for achieving the above object is a protector for transporting and storing a roll product obtained by winding a belt-like product around a core material, covering an end face of the roll product. A substrate part having a substantially circular or substantially regular polygonal shape in plan view to be protected, and a support formed by inserting a core material of the roll product or a support member for supporting the core material in the vicinity of the center of the substrate part. It consists of a hole and a leg protruding from the inner surface which becomes the roll product when the roll product is mounted on the periphery of the substrate, and the leg is inclined in the outer diameter direction of the substrate When a plurality of roll product protectors are stacked, one side of the leg slope plate in one roll product protector is the other side of the leg slope plate in the other roll product protector. Configured to overlap the surface The contents of the roll product for protector, characterized in that there.

  The invention according to claim 2 of the present invention is such that the shape of the substrate portion is substantially square in plan view, and is approximately 5 to 8 octagons in length, and the leg portion protrudes from the corner portion of the substrate portion, The side edge of a leg part and the edge of a board | substrate part are formed on the same plane, It can stand by the side edge of the said leg part, and the edge of a board | substrate part, It is characterized by the above-mentioned. Includes a roll product protector.

  In the invention according to claim 3 of the present invention, a bulged portion having a truncated cone shape or a truncated pyramid shape is provided in the vicinity of the center on the inner surface side of the substrate portion, and the bulged portion is formed on the outer surface side of the substrate portion. The roll product protector according to claim 1, further comprising a receiving portion for receiving the roll.

  The invention according to claim 4 of the present invention includes the protector for roll products according to any one of claims 1 to 3, wherein the leg portions are provided to protrude at substantially equal intervals.

  The invention according to claim 5 of the present invention includes the protector for roll products according to any one of claims 1 to 4, wherein the belt-like product is a battery separate film.

The protector for roll products of the present invention employs a flat support hole portion instead of a three-dimensional roll product support cylindrical portion, and adopts an inclined slope plate instead of an insertable cylindrical leg portion. As a result, the structure is simple and lightweight, and the leg portion is composed of an inclined plate inclined in the outer diameter direction of the base plate portion. Since one side of the slope plate overlaps with the other side of the slope plate of the legs in other protectors, the legs can be stacked compactly without obstructing, thus handling is good Therefore, a small space is also required for transportation and storage, improving transportation efficiency and storage efficiency.

  Also, if the side edge of the leg part and the edge of the board part are formed on the same plane so that they can stand on their own, this protector can be easily attached to a roll product, and this protector is attached. Roll products are difficult to roll, workability is good, and transportation and storage are easy.

In addition, when a substantially truncated cone-shaped or polygonal frustum-shaped bulged portion is provided on the inner surface side of the substrate portion, a portion in which the strip-shaped product is wound by bringing the end of the core material into contact with this portion A space corresponding to the thickness of the bulge is formed between the inner surface of the protector and the inner surface of the protector. As a result, the belt-shaped product does not come into contact with the inner surface of the protector. There is no.
In addition, if a receiving portion for receiving the bulging portion is provided on the outer surface side of the substrate portion, when the protector is stacked when not in use, the bulging portion fits into the receiving portion, so that it does not get in the way. Therefore, it can be stacked compactly without being bulky.

  Further, since the leg portions project at substantially equal intervals, the shrink film can be easily encapsulated and banded.

  The protector for roll products of the present invention is configured as described above, so that the surface of the belt-shaped product is protected from being blown or rubbed, so that the belt-shaped product that is highly required to be protected from damage such as blow or rubbed, for example, It is particularly suitable for a battery separate film or the like.

(A) is a bottom view of a protector provided with a reinforcing rib, and (b) is a DD cross-sectional view. It is the schematic which shows the roll product equipped with the conventional protector.

The roll product protector according to the present invention is a protector 1 for transporting and storing a roll product R obtained by winding a strip product R1 around a core material R2, as shown in FIGS. A substantially circular or substantially regular polygon (substantially regular octagonal in FIG. 1) substrate portion 2 that covers and protects the end face of R, and the core material R2 of the roll product R can be inserted near the center of the substrate portion 2. The support part 3 is formed with a hole 4 and a leg part 4 projecting from the inner periphery of the peripheral part of the substrate part 2, and the leg part 4 is made of an inclined plate inclined in the outer diameter direction of the substrate part 2. When a plurality of roll product protectors are stacked, one surface of the leg slope plate of one roll product protector overlaps the other surface of the leg slope plate of the other roll product protector. It is comprised by these.

  In the present invention, a support hole portion 3 is formed near the center of the substrate portion 2. The core material R2 of the roll product R or a support member to be described later is inserted into the support hole portion. As a result, for example, as shown in FIG. 2, the roll product R has the core material R2 protruding from both ends thereof as the support hole. Since the peripheral surface of the roll product R is in contact with or rubbed against the desk or the floor surface or the like is prevented by the portion 3 and suspended, the end surface of the roll product R is covered with the substrate portion 2. Scratches on the end face are also prevented.

  The substrate portion 2 is a substantially circular or substantially regular polygonal plate-like body in plan view, and covers the end face of the cylindrical roll product R, and preferably has a substantially square shape or a regular regular 5-8 in plan view. It is a square. By setting it as such a shape, even if the roll product R with the protector 1 mounted thereon is placed horizontally on a desk or floor, it is difficult to roll and easy to handle. More preferably, it is a substantially square, a substantially regular hexagon, and a regular octagon. In this case, when the roll product R to which the protector is mounted is placed horizontally, the side on the upper side of the substrate part 2 is also horizontal. As shown in FIG. 3, it becomes easy to stack the roll products R in the vertical direction. Particularly preferably, it is a substantially square and a substantially regular octagon. In this case, since the sides on both sides become vertical when placed horizontally, they can be arranged in parallel without gaps as shown in FIG. For example, it can be efficiently stored in a cardboard box.

The substrate portion 2 has an inner surface side 2A that becomes the roll product side when mounted on the roll product R, and an outer surface side 2B opposite to the inner surface side 2A, and the peripheral portion of the substrate portion 2 is in the direction of the inner surface side 2A. The leg portion 4 is provided in a protruding manner. In the present invention, the leg portion 4 is composed of a sloped plate inclined in the outer diameter direction of the substrate portion 2. Thereby, even when the protector 1 is stacked when not in use, as shown in FIG. 5, one surface of the slope plate of the leg portion 4 of the protector 1 placed on the lower side (the inner surface side 4A in FIG. 5) is upward. Since it is constituted so that it may overlap with the other side (outer surface side 4B in Drawing 5) of the slope board of leg part 4 of protector 1 placed in leg 1, leg part 4 of protector 1 placed in the lower part is stacked up It is possible to stack completely under one leg 4 and stack it extremely compactly, reducing the space required for transportation and storage, and greatly improving transportation efficiency and storage efficiency.

In the present invention, the inclined plate is not particularly limited as long as it is a plate-like body extending obliquely in a stackable manner, for example, a curved plate bent in a flat plate shape, an arc shape, or a bent plate It may be a shape, or two or more slope plates may be combined to form one leg. From the viewpoint of strength, those having an arc shape, a curved plate shape, a bent plate shape and the like are preferable. As an example of the leg portion 4, the leg portion 4 (a bent plate-like slope plate is adopted) in the embodiment shown in FIG. 1 is shown in detail in FIGS. 6 is an enlarged view of the portion of the leg 4 in FIG. 1A and its AA cross-sectional view, and FIG. 7 is an enlarged side view of the portion of the leg 4 in FIG. 1B and its BB. It is sectional drawing.
When the roll products R to which the protectors 1 are attached are stacked, the leg portions 4 are arranged so that the peripheral portions of the protectors 1 are arranged around the other roll products R even if the placement positions of the other roll products R are slightly shifted. It also plays a role in preventing the belt-shaped product from being damaged by coming into contact with the surface.
The number and arrangement of the leg portions 4 are not particularly limited, but when the substrate portion 2 is polygonal, it is preferable to provide the leg portions 4 at each corner, and by arranging the leg portions 4 at equal intervals. It is preferable because encapsulation and banding with a shrink film are easy.

  In this invention, when the shape of the board | substrate part 2 is either a substantially square by the planar view, and substantially regular 5-8 octagon, while projecting the leg part 4 from the corner | angular part of the board | substrate part 2, and the side edge of a leg part If the 4a and the edge 2a of the substrate portion are formed on the same plane, as shown in FIG. 8, the side edge 4a of the leg portion and the edge 2a of the substrate portion are in the same plane. By being grounded across a predetermined angle, it becomes possible to stand on its own and workability can be greatly improved.

  In addition, in FIG. 1, 2c is a through-hole, and since the weight of the protector 1 can be reduced and the amount of resin can be reduced, the protector can be provided at low cost. The shape of the through hole is not particularly limited, and may be any of a circle, an ellipse, a polygon, and the like. Further, the number of through holes is not particularly limited, and may be appropriately determined so as to maintain a necessary strength in consideration of the weight of the roll product.

In the present invention, as shown in FIGS. 9 and 10, the bulging portion 5 can be provided on the inner surface side of the substrate portion 2. For example, as shown in FIG. 11, the support member 7 is inserted into the hollow portion of the core material R2 around which the strip-shaped product R1 is wound, and the end of the support member 7 is inserted into the support hole 3 of the protector 1, This protector 1 is suitable for collectively protecting a plurality of (three in the example shown in FIG. 11) roll products R. In addition, cushion material R3 is interposed between each roll product R, and damage to strip | belt-shaped product R1 by the collision of roll products R is prevented.
According to such a protector 1, the core material R <b> 2 is in contact with the bulging portion 5, and the thickness of the bulging portion 5 is between the portion around which the strip-shaped product R <b> 1 is wound and the inner surface of the substrate portion 2. As a result, the strip-shaped product R1 does not come into contact with the inner surface of the substrate portion 2. Therefore, even if the gap between the pair of protectors 1, 1 is fastened with a band (not shown) or the like, the roll product R Therefore, the edge of the belt-shaped product R1 can be prevented from being damaged or bent. Although the height of the bulging portion 5 cannot be generally defined by the size of the protector 1, the deflection of the material used, the size of the roll product, etc., about 5 to 20 mm is usually preferable.

  In order to protect the rolled product R around which the wide strip-shaped product R1 is wound, for example, as shown in FIG. 12, a hat-shaped support member 7 having a collar portion around the end of the cylindrical member is connected to the core from the support hole portion 3. It can also be used by fitting the roll product R into the hollow hole of the material R2.

The protector 1 provided with such a bulging portion 5 is equivalent to the thickness of the bulging portion 5 when the bulging portion 5 comes into contact with the outer surface side 2B of the substrate portion 2 when the protectors 1 are stacked when not in use. Since it becomes bulky, as shown in FIG. 10, it is preferable to provide a receiving portion 6 that can receive the bulging portion 5 on the outer surface side 2B of the substrate portion 2 in order to prevent this.

  When the shape of the bulging portion 5 is columnar, that is, when the shape and size of the lower surface and the upper surface are substantially equal, if the receiving portion 6 having substantially the same shape as the bulging portion 5 is provided, the rising portion of the bulging portion 5 Therefore, it is preferable that the shapes of the bulging portion 5 and the receiving portion 6 are substantially a truncated cone shape or a truncated pyramid shape, that is, the rising portion has a slope shape. .

  About the inner surface shape of the board | substrate part 2, in the case of the protector 1 used with respect to the roll product R which wound the strip | belt-shaped product R1 directly around the core material R2, as shown in FIG. Since the end face of the roll product R directly, that is, the edge of the belt-like product R1, comes into contact, it is preferable to have a smooth flat surface so as not to damage it, and it is also preferable to provide a cushioning sheet if necessary. On the other hand, in the case of the protector 1 used in a state where the roll product R wound with the strip-shaped product R1 is not in direct contact with the inner surface of the substrate portion 2 as shown in FIGS. 11 and 12, the shape of the inner surface of the substrate portion 2 Is not particularly limited, and for example, a reinforcing rib or the like can be provided.

  On the other hand, the shape of the outer surface of the substrate portion 2 is not particularly limited, but in order to reduce the weight of the protector 1 and ensure the strength, it is preferable to provide reinforcing ribs 2b as shown in FIG. The method of providing the reinforcing rib 2b is not particularly limited. FIG. 13 shows an example in which a rib is provided on the protector provided with the bulging portion 5 shown in FIG. 9, but it may be provided on a protector not provided with the bulging portion 5 as shown in FIG. Needless to say, it is good.

In the present invention, a band groove (not shown) can be provided on the outer surface of the peripheral edge of the substrate portion 2. When the band groove is provided, the protector 1 and the roll product are tied together through the band groove with the protector attached to the roll product, thereby preventing the protector 1 from being unintentionally detached from the roll product R. Troubles such as cargo collapse during transportation and storage can be prevented.
Further, instead of applying a band, the whole can be wrapped with a shrink film or the like (not shown), and both a band and a shrink film can be used in combination.

  Although it does not specifically limit as long as it has sufficient intensity | strength as hard rigid resin which comprises the protector 1 for roll products of this invention, ABS, AAS, AES, AS, PS, PMMA, PVC, PA, PP, PE, PBT, PET Etc. can be exemplified.

  The belt-like product to which the protector for roll products of the present invention is applied is not particularly limited, and examples thereof include plastic film, plastic sheet, paper, cloth, etc., but in particular, a battery that is highly required to be protected from being hit or rubbed. It is useful for a separate film.

  As described above, the protector for roll products of the present invention has a simple structure and is lightweight, and when not in use, it is not bulky even when stacked, and can be stacked in a compact manner. Since a vast space is not required for transportation and storage, transportation efficiency and storage efficiency can be greatly increased, and its usefulness is greatly increased.
