  However, when the width of the photosensitive material sheet (sheet material) is shorter than the length of the winding core, a gap is formed between the end face of the package and the protective member. For this reason, there exists a possibility that winding deviation may generate | occur | produce in a package (roll-shaped object) by the impact at the time of transportation.

  An object of the present invention is to provide a roll-shaped product packaging unit, a roll-shaped product package, and a roll-shaped product packaging method that can protect the roll-shaped product and prevent the roll-shaped product from being unwound.

  The roll-shaped product packaging unit of the present invention includes a packaging container in which a roll-shaped material having a long sheet material wound around a core is accommodated, and a winding core protruding from the end surface of the roll-shaped material. The part has a through-hole, and is arranged between the end face of the roll-like object and the end face of the core in a state of protruding in the radial direction of the end face of the roll-like object from the outer periphery of the end face of the roll-like object. And the support members disposed on both ends of the roll-shaped object are in contact with the inner wall surface of the packaging container, and the roll-shaped object accommodated in the packaging container is floated in the air. It is characterized by being supported in a state.

  According to the present invention, the support members are arranged on both ends of the roll-like material by inserting the through-holes of the support member into the overhang portions of the winding core that are projected from the respective end portions of the roll-like material. And the roll-shaped thing of the state by which the supporting member was distribute | arranged to the both ends is accommodated in the container box for packing. At this time, since the support member is in a state of projecting in the radial direction of the end face of the roll-like object from the outer periphery of the end face of the roll-like object, only the support member is in contact with the inner wall surface of the packaging container box, Rolls do not touch. Accordingly, since the roll-shaped object can be supported in the air in the packing container box, the roll-shaped object can be protected from quality deterioration due to contact with the packing container box.

  Moreover, since a support member is arrange | positioned at the both ends of a roll-shaped object by inserting a core in a through-hole, it can be brought close to the end surface of a roll-shaped object. For this reason, the roll-shaped object can be supported in a state in which there is almost no gap between the support member and the roll-shaped object. Accordingly, it is possible to prevent the roll-like material from being displaced due to an impact during transportation.

  Preferably, the cushioning member is provided in a gap between the inner side wall of the packaging storage box and the support member, and is longer than the interval between the inner side wall of the packaging storage box and the support member, and has a flexible cushion member. In this case, since the cushion member is arranged in a state of being contracted in the gap between the inner wall of the packing storage box and the support member, the support member is caused by the restoring force of the cushion member in the direction of pressing toward the roll-shaped object. Pressure is applied. Accordingly, the support member is sandwiched between the roll-shaped object and the cushion member, and is stably disposed on both ends of the roll-shaped object, so that it is possible to more reliably prevent the roll-shaped object from being unwound. . The cushion member having such flexibility is made of, for example, polyethylene.

  In this case, the length of the cushion member is preferably 0.1 mm to 30 mm longer than the distance between the inner wall of the packaging storage box and the support member. Thereby, the pressure which suppresses winding deviation of a roll-shaped thing can be applied to a support member, smoothing the attachment or removal of the cushion member to the space | interval of the inner wall of a packaging storage box, and a support member.

  Preferably, an end face protection member is provided between the end face of the roll-like object and the support member and attached to cover the end face of the roll-like object. Thereby, the damage by contact with a supporting member etc. can be prevented, and the end surface of a roll-shaped object can be protected.

  The roll-shaped product packaging body of the present invention is characterized in that a roll-shaped product having a long sheet material wound around a winding core is packed by the roll-shaped product packaging unit.

  According to such a roll-shaped product packaging body of the present invention, since the roll-shaped product is packed using the above-mentioned roll-shaped product packaging unit, the roll-shaped product is damaged or wound when it is stored or transported. Can be reduced.

  One suitable roll-like product for such a roll-like package is one in which a sheet material containing a photosensitive material is wound around a winding core and then light-shielded and packaged.

  Moreover, it is preferable that the roll-like object is further provided with a protective sheet that covers the end face of the roll-like object. Thereby, the end surface of a roll-shaped object can be protected.

  The core is preferably a hollow cylindrical body formed of polyethylene resin as a main component and having a thickness of 0.5 mm to 1.6 mm. Thereby, it can reduce in weight compared with a solid cylindrical body, and it can prevent that a wrinkle generate | occur | produces in a roll-like thing because a roll-like thing bends with dead weight.

  The present invention is a roll-like material packing method for packing a roll-like material having a long sheet material wound around a winding core in a packaging storage box, and projecting from the end surface of the roll-like material A step of preparing a support member that has a through-hole through which the projecting portion of the core is inserted and is arranged in a state of projecting in the radial direction of the end face of the roll-like object from the outer periphery of the end face of the roll-like object; A step in which a projecting portion of the core is inserted into the through-hole and a support member is disposed between the end surface of the roll-shaped material and the end surface of the core; And a step of accommodating the container in a packaging container.

  According to the present invention, the support member is in a state of projecting in the radial direction of the end face of the roll-like object from the outer periphery of the end face of the roll-like object. When an object is accommodated in the packaging container, only the support member contacts the inner wall surface of the packaging container, and the roll-shaped object does not contact. Therefore, since the roll-like object can be supported in the air in the packing container, the packed roll-like object can be protected. Moreover, since the support member is disposed on both ends of the roll-shaped object by inserting the core through the through hole, the support member can be brought into a state of being close to the end surface of the roll-shaped object. Therefore, since the roll-like object can be supported in a state where there is almost no gap between the support member and the roll-like object, the roll-like object can be prevented from being unwound due to an impact during transportation. .

  According to the present invention, it is possible to provide a roll-shaped product packaging unit, a roll-shaped product package, and a roll-shaped product packaging method capable of protecting a roll-shaped product and preventing roll-off of the roll-shaped product.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, the same code | symbol shall be used for the same element and the overlapping description is abbreviate | omitted.

  FIG. 1 is an exploded perspective view of a roll-shaped product package according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a roll-shaped product included in the roll-shaped product package shown in FIG. As shown in FIG. 1, the roll-shaped object packing body 1 includes a roll-shaped object 2 and a roll-shaped object packing unit 3.

  As shown in FIG. 2, the roll-shaped material 2 is a roll-shaped sheet material including a photosensitive sheet and a long sheet material 5 wound around a hollow cylindrical core 4 to form a roll shape. And a packaging material 6 for packaging 5.

  The sheet material 5 in this embodiment is a wide and long photosensitive material sheet. The wide and long photosensitive material sheet generally refers to a photosensitive material having a width of 400 mm to 2000 mm and a length of 100 m to 1000 m. However, of course, other widths and lengths may be used.

  Examples of such a sheet material 5 include, for example, a trade name “FOTEC” manufactured by Hitachi Chemical Co., Ltd., a trade name “Sanfort” manufactured by Asahi Chemical Industry Co., Ltd., and trade names “Alfo”, “Laminer”, “Dina” manufactured by Nichigo Morton Co., Ltd. Examples include masks, conform masks, and DuPont's brand name Liston.

  The packaging material 6 includes a light-proof and moisture-proof material, and is fixed with an adhesive tape 7 or the like in a state of covering the entire sheet material 5. At this time, the packaging material 6 is folded into the hollow portion of the core 4 at the openings 4 a and 4 b at both ends of the core 4, so that the entire sheet material 5 is prevented from entering light and moisture into the sheet material 5. Covering.

  The winding core 4 is a hollow cylindrical body composed mainly of polyethylene resin or FPC resin. The core for winding the sheet material 5 as a photosensitive material sheet is generally 0.4 mm thick. However, if the wall thickness is 0.4 mm or less, when the wide and long sheet material 5 is wound up and left for a long period of time, the core is deflected by its own weight, and the sheet material 5 is wrinkled. May occur. On the other hand, if the wall thickness is too thick, it is not preferable from the viewpoints of economy and workability. Therefore, the thickness of the core 4 is desirably 0.5 mm to 1.6 mm, and more desirably 0.8 mm.

  Further, the roll-like object 2 is provided with a protective sheet 8 that covers the end surface. The protective sheet 8 has, for example, a multilayer structure of two or more layers of an end face contact portion film and a desiccant layer, or a single layer structure composed of a low moisture permeable film and a desiccant layer. By providing such a protective sheet 8 on the end face of the roll-like object 2, the end face of the roll-like object 2 can be protected, and the removal of moisture from the sheet material 5 and the entry of moisture into the sheet material 5 can be performed. Can be prevented.

  For example, as shown in FIG. 2, the protective sheet 8 is fixed to the roll-shaped object 2 with an adhesive tape 9 or the like. Thereby, the winding slip at the time of transportation and handling can be prevented. Further, the adhesive part of the pressure-sensitive adhesive tape 9 is not desirable from the viewpoint of workability and economical efficiency at one end of the roll-like object 2 because the function of preventing winding deviation does not function sufficiently at one place. Therefore, the number is preferably 2 to 8 and more preferably 4 locations.

  By the way, as the roll-like material is closer to the core, the pressure applied from the outer peripheral side of the roll-like material is larger. In a roll-like material in which a sheet material having a resin layer such as a photosensitive material sheet is wound, The phenomenon that the composition protrudes, that is, the edge fusion phenomenon (fusing phenomenon of the side surface portion of the photosensitive element roll) is likely to occur. This phenomenon is facilitated by the influence of humidity. Therefore, by providing the protective sheet 8 provided with the desiccant layer as described above on the end face of the roll-like object 2, it is possible to make the edge fusion phenomenon difficult to occur.

  FIG. 3 is a diagram showing a state in which the roll-like object 2 is packed by the roll-like object packing unit 3 shown in FIG. FIG. 3 shows the inside of a packaging storage box 10 (described later) in which the roll-shaped object 2 is stored. Below, with reference to FIG. 1 and FIG. 3, the roll-shaped article packing unit 3 is demonstrated.

  The roll-shaped article packing unit 3 includes a packaging storage box 10 in which the roll-shaped article 2 is accommodated, and a support member 11, a cushion member 12, and an end surface protection member 13 disposed on both ends of the roll-like object 2. Is done. And the roll-shaped article packaging body 1 comprises the roll-shaped article 2 by which the supporting member 11, the cushion member 12, and the end surface protection member 13 were distribute | arranged to the both ends are accommodated in the packaging storage box 10, and is packed. Is done.

  The packaging storage box 10 includes a main body portion 14 in which a roll-like object 2 in which a support member 11, a cushion member 12, and an end surface protection member 13 are arranged on both ends is accommodated, and a main body portion 14 in which the roll-like object 2 is accommodated. And a lid portion 15 that covers the lid. Such a packaging container 10 is preferably formed of a light-shielding material when the sheet material 5 is not provided with the packaging material 6 containing the light-shielding material.

  The support member 11 has a plate-like shape, and has a through-hole 21 through which the projecting portion 20 of the core 4 projecting from the end surface of the roll-like object 2 is inserted at the approximate center thereof. The diameter of the through hole 21 is large enough to be loosely fitted to the overhanging portion 20. Such a support member 11 has a size that fits in the width direction in the main body portion 14 of the packaging container 10 from the viewpoint of stability during packing and prevention of winding deviation, and has a thickness of 0.5 mm or more. It is preferable to do this.

  Further, the support member 11 according to the present embodiment has an area larger than the area of the end face of the roll-like object 2. Therefore, when the projecting portion 20 is inserted into the through hole 21 and disposed between the end face of the roll-like object 2 and the end face of the core 4, the end face of the roll-like object 2 is more than the outer periphery of the end face of the roll-like object 2. It will be in the state of projecting in the radial direction.

  The materials used for the support member 11 and the packaging container 10 described above are a mixture of thermoplastic resin, pulp and resin, taking into consideration, for example, recyclability after use, ease of manufacture, handleability, environmental load and strength. And the like. The thermoplastic resin is not particularly limited as long as it can be injection-molded or blow-molded. For example, general resins such as polyethylene, polystyrene, polyamide, polyacetal, polycarbonate, and polypropylene can be used, and a block copolymer of polyethylene and polypropylene can be used. Coalescence may be used. In addition, as a material in which pulp is mixed with a thermoplastic resin, for example, rosin, a similar substance derived from rosin, a kind of petroleum resin, or a mixture thereof is selected as a plasticizer by 15 to 60%. A thermoplastic composition containing 50% by mass of a thermoplastic resin containing 20 to 60% by mass of plant fibers and 50% by mass of non-wood fibers by increasing the fluidity of the resin and making the melting flow rate (MFR) 20-100. % Or more of the thermoplastic composition, plant fibers and non-chlorine thermoplastic resins. As a manufacturing method, for example, it is manufactured using an injection molding and flow molding method as described in a practical plastic molding processing manual (edited by the All Japan Plastics Molding Industry Association).

  The cushion member 12 is a flexible hollow cylindrical body made of polyethylene, and a through hole 22 through which the projecting portion 20 of the core 4 is inserted is formed along the axial direction. The cushion member 12 is disposed on the opposite side of the roll-shaped object 2 with respect to the support member 11 by inserting the protruding portion 20 through the through hole 22. The length of the cushion member 12 in the axial direction is longer than the distance between the inner wall of the packaging container 10 and the support member 11. Therefore, as shown in FIG. 3, the cushion member 12 is arranged so as to fill a gap between the inner wall of the packaging storage box 10 and the support member 11. Examples of other materials for the cushion member 12 include polypropylene.

  The end surface protection member 13 is a ring-shaped member having a through hole 23 through which the projecting portion 20 of the core 4 is inserted. The through hole 23 has a diameter that is, for example, 0.1 mm to 20 mm larger than the diameter of the core, and is loosely fitted to the overhanging portion 20. The end face protection member 13 is disposed between the support member 11 and the roll-like object 2 so as to cover the end face of the roll-like object 2 by inserting the projecting portion 20 through the through hole 23. It is desirable that the thickness of the end surface protection member 13 is, for example, 0.3 mm or more, and the surface facing the end surface of the roll-shaped object 2 has a size that can completely cover the end surface of the roll-shaped object 2. Moreover, as a material of the end surface protection member 13, a polyethylene terephthalate, a calcium chloride type inorganic compound composite body, etc. are mentioned. Such an end face protection member 13 has a function of protecting the end face of the roll-like object 2 and preventing, for example, damage to the end face of the roll-like object 2 due to contact with the support member 11.

  When packing the roll-like object 2 by the roll-like article packing unit 3 as described above, first, the protruding part 20 of the core 4 is inserted into the through hole 23 of the end face protection member 13, thereby End face protection members 13 are attached to both ends. Next, the projecting portion 20 is inserted into the through hole 21 of the support member 11, and the end surface protection member 13 is supported by the roll-shaped material 2 between the end surface of the roll-shaped material 2 and the end surface of the core 4. The member 11 is attached. Next, the cushion member 12 is attached to the opposite side of the roll-like object 2 with respect to the support member 11 by inserting the protruding portion 20 of the core 4 into the through hole 22 of the cushion member 12. In this state, the roll-shaped object 2 is accommodated in the main body 14 of the packaging container 10 and the lid 15 is closed. When the roll-shaped object 2 is accommodated in the main body 14, the roll-shaped object 2 is accommodated in the main body 14 while the cushion member 12 is contracted in the axial direction. Thereby, the roll-shaped object 2 is packed and the roll-shaped object package 1 can be obtained.

  The roll-shaped product packaging body 1 as described above is in a state in which the roll-shaped product 2 is sandwiched between the support members 11 that protrude in the radial direction of the end surface of the roll-shaped product 2 from the outer periphery of the end surface of the roll-shaped product 2. It has become. Accordingly, only the support member 11 is in contact with the inner wall surface of the packaging storage box 10, and the roll-like object 2 is supported in a floating state. Thereby, the quality degradation of the roll-shaped object 2 by the contact with the container 10 for packing, etc. can be prevented. Further, since the support member 11 according to the present embodiment has a size that fits in the width direction in the main body portion 14 of the packaging container 10, the amount of movement in the packaging container 10 during transportation or the like. Is reduced and can be stably packed.

  In addition, since the support member 11 is disposed on both ends of the roll-shaped object 2 by inserting the core 4 through the through hole 21, a gap is created between the roll-shaped object 2 and the end surface of the core 4. The roll-shaped object 2 can be pinched | interposed through the end surface protection member 13 without. Thereby, the roll shift | offset | difference of the roll-shaped thing 2 which arises by the impact at the time of conveyance etc. can be prevented.

  Further, a cushion member 12 made of polyethylene and having flexibility is disposed in a state of being contracted in a gap between the inner wall of the main body portion 14 of the packaging container 10 and the support member 11. For this reason, the pressure by the restoring force of the cushion member 12 is applied to the support member 11 in the direction in which the support member 11 is pushed toward the roll-like object 2 side. Accordingly, since the roll-like object 2 is pressed from both ends by the two support members 11, the roll-like object 2 is more reliably prevented from being unwound.

  In this case, the length of the cushion member 12 is preferably 0.1 mm to 30 mm longer than the distance between the inner wall of the main body 14 of the packaging container 10 and the support member 11. Thereby, the pressure which suppresses winding deviation of the roll-shaped object 2 is applied to the support member 11 while smoothly attaching and removing the cushion member 12 to and from the interval between the inner wall of the packaging container 10 and the support member 11. Can do. Further, the end surface of the cushion member 12 is in contact with 50% or more of the area of the surface of the support member 11 facing the roll-like object 2 in order to transmit a sufficient force for preventing the winding deviation to the support member 11. It is desirable to have an area.

  Moreover, the roll-shaped object packing unit 3 according to the present embodiment can be used repeatedly after the roll-shaped object 2 is taken out. For this reason, the amount of waste generated is reduced, and the influence on the environment can be reduced.

  Moreover, you may arrange | position the cushion member which has a softness | flexibility also in the area | region located between the two support members 11 and enclosed by the inner wall of the packaging storage box 10, and the roll-shaped object 2. FIG.
