Description

  The present invention relates to a film packaging body in which a film winding body in which a film is wound in a roll shape is packaged, and a film packaging method.

  Conventionally, as shown in FIG. 10, when a film winding body 50 in which a film is wound around a core 51 is transported, for example, in order to prevent the film from being loosened or unwound by vibration or impact during transportation, for example, A packaging form was adopted in which a winding core fixing jig 53 was fixed from the outside of the winding core 51 and the film winding body 50 via a cushion material 52 and stored in the outer box 54 in this state.

  If the film is unwound, the film may not be set on the transport machine when used, or the film may meander. For this reason, a material such as a thick and strong plywood, plastic plate, metal plate or the like is used as the core fixing jig 53, or the outer box 54 is formed using these materials.

JP 2003-192081 A

  Here, the outer box 54 has a slightly larger storage space size than the stored item for convenience of packing and unpacking. Therefore, the film winding body 50 clamped by the winding core fixing jig 53 may move in the outer box during conveyance, and the film may be loosened or unwound.

  In particular, when a film in which a resin layer is laminated on a support such as an adhesive film has a high tension at the time of winding on a reel, the stress related to the film winding body 50 increases cumulatively in the vicinity of the core, Since there is a possibility that the resin layer protrudes, it is wound with a lower tension than usual. For this reason, resistance to impacts and vibrations is low, and there is a tendency that winding looseness and winding slip easily occur.

  For the same reason, the film winding body 50 sandwiched by the core fixing jig 53 cannot be further tightened with a PP band or the like so as to prevent the film from being pressed against the core fixing jig 53 as a countermeasure against winding deviation. .

  Accordingly, the present invention provides a film packaging body and a film packaging method for preventing the occurrence of winding slippage or loosening during transportation even in the film winding body 50 in which the film is wound around the core 51 with the tension lowered. The purpose is to provide.

To solve the problems described above, the film packaging body according to the present invention, at least one support plate or the outer box is a film packaging body is a plastic cardboard, wound into a roll film to the winding core A pair of film winding bodies, a pair of support plates for sandwiching the film winding body, and a pair of base plates that are fitted to the cores from the outside of the pair of support plates, and fix the support plates to the cores. An outer box that is formed of a material that exhibits elastic deformation with respect to bending stress and is curved outwardly in which a storage body comprising the film winding body provided with the fixing cap and the support plate is stored. The outer box has a flap at the top of the outer box and an open end that can open the flap, and a width between the pair of fixed caps is in contact with the cap of the outer box. larger than the width between the inner surfaces of The pair of support plates has a projecting piece provided by further extending the central portion of the upper side of the support plate upward, and the projecting piece is stored in the outer box. When bent by the flap provided on the open end side of the outer box, it is bent more inward than between the support plates .

The film packaging method according to the present invention includes a film winding body in which a film is wound in a roll shape around a core, a pair of support plates that sandwich the film winding body, and the outside of the pair of support plates. A pair of fixing caps that are fitted to the winding core and fix the support plate to the winding core, and a material that exhibits elastic deformation against bending stress, and the fixing cap and the support plate are provided. An outer box that is curved outward to store a storage body composed of the film winding body, and the outer box has a flap at an upper portion of the outer box and an open end that can open the flap. The width between the pair of fixed caps is larger than the width between the pair of inner surfaces in contact with the cap of the outer box, and the flexural modulus of the support plate is equal to or greater than the flexural modulus of the outer box, Storing the storage body while elastically deforming the box

  According to the present invention, the storage space of the outer box has a width equal to or smaller than the width between the fixed caps of the storage body before the storage body is stored. Since the outer box is formed of a material that exhibits elastic deformation while causing bending stress to exist with respect to an external load, the outer box is curved outward when the storage body is stored.

  As a result, the film packing body presses the storage body with the stress in the width direction of the storage body generated in the outer box, thereby preventing the film winding body from swinging inside the outer box during conveyance. Unwinding and loosening can be prevented.

Further, the drawings are schematic, and the ratio of each dimension may be different from the actual one. Specific dimensions should be determined in consideration of the following description. Moreover, it is a matter of course that portions having different dimensional relationships and ratios are included between the drawings.

  As shown in FIG. 1, a film packaging body 1 to which the present invention is applied includes a film winding body 4 in which a film 2 is wound around a core 10 in a roll shape, and a pair of sandwiching the film winding body 4. Support plates 5, 5, a pair of fixing caps 6, 6 that fix the support plate 5 to the core 10, and an outer box 7 that houses the film winding body 4 provided with the fixing cap 6 and the support plate 5. Have.

[Film roll]
As shown in FIG. 2, the film winding body 4 is obtained by winding a long film 2 around a core 10 in a roll shape. The core 10 has a rotation shaft for rotating the film winding body 4 and a shaft hole 10a into which a fixing cap 6 described later is inserted. One end of the film 2 in the longitudinal direction is connected to the core 10, and the film 2 is wound around the core 10.

  The core 10 can be formed using, for example, various plastic materials. The core 10 may be subjected to electrostatic treatment on the surface in contact with the film 2. Examples of the method for applying the electrostatic treatment include a method of applying a compound such as polythiophene to the core 10.

  The film 2 wound around the core 10 and constituting the film winding body 4 includes an anisotropic conductive film (such as COG mounting for mounting electronic components on a circuit board or the like, FOG mounting for connecting substrates to each other) Examples thereof include ACF (Anisortropic Conductive Film) or a conductive adhesive film that connects a solar cell electrode and a tab wire.

  If an anisotropic conductive film is demonstrated to an example as the film 2, the film 2 is provided with the peeling film 14 and the binder resin layer 15 formed on the peeling film 14, as shown in FIG. The film is formed in a tape shape and is wound around the core 10 so that the release film 14 is on the outer peripheral side.

  As the release film 14, for example, a PET (Poly Ethylene Terephthalate) film is used, and a release agent such as silicone is applied to one side on which the binder resin layer 15 is laminated. In the binder resin layer 15, conductive particles 16 are dispersed in an adhesive composition containing a film-forming resin, a polymerizable resin, a polymerization initiator, and an additive such as a silane coupling agent or an inorganic filler. Yes.

  The film winding body 4 can be manufactured as follows. First, the film-forming resin, the polymerizable resin, the polymerization initiator, the conductive particles 16, and the silane coupling agent and the inorganic filler as the binder resin composition are dissolved in a solvent. As the solvent, toluene, ethyl acetate or the like, or a mixed solvent thereof can be used. The long film 2 is obtained by apply | coating the solution for resin production obtained by making it melt | dissolve to the peeling film 14, and volatilizing a solvent. Thereafter, the film 2 is wound around the reel 3, thereby obtaining the film winding body 4.

[Support plate]
The support plate 5 protects the film winding body 4 from impacts and vibrations by sandwiching the film winding body 4 from the outside of the core 10, while allowing bending stress to be inherent to an external load. It is formed using, for example, plastic cardboard or the like that exhibits elastic deformation. Further, in order to increase the strength, a structure in which one support plate 5 is bent as shown in FIG. 1 may be adopted.

  The support plate 5 is overlapped with a shaft hole 10 a formed in the core 10, and a fitting port 5 a into which a later-described fixing cap 6 is fitted together with the shaft hole 10 a is formed. The support plate 5 is fixed by the fixing cap 6. Then, the film winding body 4 is clamped without protruding.

  The support plate 5 is formed in a substantially rectangular shape according to the shape of the storage space 7a of the outer box 7 described later. Further, the corners of the support plate 5 are chamfered in an R shape.

[Fixed cap]
The fixing cap 6 that fixes the support plate 5 to the core 10 is formed using a material that is not easily deformed by stress, such as hard plastic or metal. As shown in FIG. 4, the fixed cap 6 is locked around the fitting port 5 a of the support plate 5 and the insertion hole 6 a that passes through the shaft hole 10 a formed in the core 10, and the periphery of the fitting port 5 a of the support plate 5. And a flange-like locking portion 6b. The film winding body 4 sandwiched between the fixed cap 6 and the support plate 5 constitutes a storage body 17 stored in the outer box 7. At this time, the fixing cap 6 is fitted from the outside of the pair of support plates 5, 5, so that the distance between the outer surfaces of the pair of locking portions 6 b is that of the storage body 17 stored in the outer box 7. Maximum width W1.

[Outer case]
Similar to the support plate 5, the outer box 7 that stores the storage body 17 composed of the film winding body 4 sandwiched between the support plate 5 and the fixed cap 6 is elastically deformed while causing bending stress to exist with respect to an external load. For example, it is formed using a plastic cardboard or the like. The outer box 7 is provided with a storage space 7a for storing a storage body by being assembled into a box shape in the same manner as a corrugated cardboard for normal packaging. The outer box 7 is sealed by storing the storage body in the storage space 7a, and then closing the inner flap and the outer flap on the opening end side.

  In the present invention, the storage space 7 a of the outer box 7 has a width W <b> 2 that is less than or equal to the width W <b> 1 between the fixed caps 6, 6 of the storage body 17 before the storage body 17 is stored. Since the outer box 7 is formed of a material that exhibits elastic deformation while allowing bending stress to exist with respect to an external load, the outer box 7 curves outward when the storage body is stored (FIG. 1).

  Thereby, the film packaging body 1 presses the storage body 17 by the stress in the width W1 direction of the storage body generated in the outer box 7, and thereby the film winding body 4 swings inside the outer box 7 during conveyance. Is prevented, and the winding and loosening of the film 2 can be prevented. The difference between the width W1 between the fixed caps 6 and 6 of the storage body and the storage space 7a of the outer box 7 varies depending on the material, the elastic modulus, etc., but at least the outer box 7 stores the storage body. The yield point is not reached depending on the deformation due to, and the range shows elastic deformation.

The bending elastic modulus of the support plate 5 is preferably equal to or higher than the bending elastic modulus of the outer box 7. Thus, even when stress occurs outer box 7 is curved, because the support plate 5 flexural modulus is the elastic modulus of the outer box least equivalent, less deformation than the outer box 7. Therefore, the support plate 5 does not apply an excessive load to the film wound body 4 and can prevent deformation and collapse. The support plate 5 may have a higher flexural modulus by using a material different from that of the outer box 7, or may be made of the same material as the outer box 7 and thicker than the outer box 7 or a plurality of sheets may be used. The bending elastic modulus may be increased.

[Projection piece]
The support plate 5 may be provided with a protruding piece 20 that protrudes from the fixed cap 6 when the winding core 10 is sandwiched. The protruding piece 20 is provided by further extending the central portion of the upper side of the support plate 5 upward. When the protruding piece 20 is packed in the outer box 7, as shown in FIG. When the inner flap 21 and the outer flap 22 are closed, the flap is pressed and bent inward from the support plate 5.

  As a result, in the film package 1, stress accompanying the bending of the protruding piece 20 occurs on the support plate 5, and the storage body 17 can be fixed to the outer box 7 in the height H direction. Therefore, the film packaging body 1 holds the film winding body 4 in the height H direction of the storage body 17 in addition to the stress in the width W1 direction of the storage body 17 generated in the outer box 7, and thereby the film winding during transportation. The body 4 is further prevented from swinging inside the outer box 7, and the film 2 can be prevented from being unwound and loosened.

  As shown in FIG. 5, the support plate 5 may have the protruding piece 20 inserted between a pair of inner flaps 21 on the open end side of the outer box 7. Thereby, since the support plate 5 is provided with a pair of inner flaps 21 on both sides of the protruding piece 20, swinging in the rotational direction θ on the inner flap 21 side is restricted. Here, since the protruding piece 20 is formed in the most distant position from the center part in which the winding core 10 and the fixing cap 6 of the storage body 17 were formed, the support plate 5 is rotated by the inner flap 21 in the rotation direction of the protruding piece 20. The swinging of the storage body can be efficiently suppressed only by lightly pressing the swinging toward θ.

  In addition, the longer the distance from the center of the storage body 17 to the protruding piece 20 whose swing is restricted by the pair of inner flaps 21, the film package 1 can be efficiently controlled with a weak force. Therefore, the center of the side surface of the outer box 7 that comes into contact with the support plate 5 and the center of the storage body, that is, the position where the winding core 10 and the fixing cap 6 are provided do not necessarily have to coincide with each other.

[Grip part]
Further, as shown in FIG. 6, the support plate 5 may be provided with a gripping portion 23 that grips the pair of support plates 5 on the protruding piece 20. The grip part 23 can be formed, for example, by providing an opening 23 a in the protruding piece 20. By providing the grip portion 23, the film package 1 can easily take out the storage body from the outer box 7 by gripping the grip portion 23. That is, when the outer box is unpacked, the projecting piece 20 bent by the flap rises, so that the grip portion 23 can be easily gripped. Therefore, the film packaging body 1 can be formed in a short time even in a state where the width W2 of the storage space 7a of the outer box 7 is narrower than the width W1 of the storage body 17 and a stress in the W1 direction is applied to the storage body 17. 7 can be removed.

  In addition to providing the opening 23 a, the gripping part 23 may be formed by providing a concave or convex part on the protruding piece 20.

  Further, as shown in FIG. 7, the support plate 5 may be formed with protruding pieces 20 on both sides of the storage body 17 in the vertical direction. As a result, as shown in FIG. 8, in the film packaging body 1, the protruding piece 20 is pressed by the vertical flap of the outer box 7, and the swing in the height H direction can be further restricted.

  In addition to providing the protruding piece 20 only at the center of the upper side and / or the lower side, the support plate 5 is provided with notches 25 in the height direction on the upper side and / or the lower side, as shown in FIG. You may leave both sides.

  Next, examples of the present invention will be described. In the present embodiment, the size relationship between the maximum width W1 of the storage body composed of the film winding body sandwiched between the support plate and the fixed cap and the width W2 of the storage space of the outer box is changed, and the protrusion piece and the gripping portion Samples of the film package with different presence or absence were prepared, and the winding deviation after the drop test, the winding deviation after the vibration test, and the time for taking out the storage body from the outer box were measured and evaluated.

  In Example 1, a PET film having a thickness of 38 μm was used as a film wound around a film winding body. The winding length is 1000 m. In Example 1, the width (maximum width of the storage body) W1 between the locking portion outer surfaces of the fixed cap is 159 mm, and the width W2 of the storage space of the outer box is 152 mm.

  The elastic modulus of the outer box is 66 in the flow direction (MD: Machine Direction) and 8.6 in the vertical direction (TD: Transverse Direction). By using two pairs of support plates, the elastic modulus is 127 in the flow direction (MD) and 18.6 in the vertical direction (TD), respectively. That is, in Example 1, the support plate has a higher flexural modulus than the outer box. The elastic modulus was measured according to JIS K 7203.

  Further, the support plate according to the first embodiment is provided with a protruding piece on the upper side, and this protruding piece is provided between the inner flaps of the outer box, and swinging in the rotation direction θ is restricted. In addition, the holding part was formed in this protrusion piece by providing opening.

  Example 2 was made the same conditions as Example 1 except that a conductive adhesive film (SP104A1) manufactured by Dexerials Co., Ltd. was used as the film wound around the film winding body. Since the film winding body according to Example 2 wound the conductive adhesive film, the film winding body was wound at a lower tension than Example 1.

  In Example 3, a conductive adhesive film (SP104A1) manufactured by Dexerials Corporation was used as a film wound around the film winding body. Further, in Example 3, the width (maximum width of the storage body) W1 between the outer surfaces of the locking portion of the fixed cap is 147 mm, and the width W2 of the storage space of the outer box is 140 mm. The elastic modulus of the outer box is 66 in the flow direction (MD: Machine Direction) and 8.6 in the vertical direction (TD: Transverse Direction). The elastic modulus of the pair of support plates is 66 in the flow direction (MD) and 8.6 in the vertical direction (TD). That is, in Example 3, since the support plate is made of the same material as the outer box, it has the same bending elastic modulus. In addition, no protruding piece is provided on the support plate according to the third embodiment.

  Example 4 has the same conditions as Example 2 except that no protruding piece is provided on the support plate.

  In Example 5, the width between the outer surfaces of the locking portion of the fixed cap (maximum width of the storage body) W1 and the width W2 of the storage space of the outer box were both set to 147 mm. The elastic modulus of the outer box and the elastic modulus of the pair of support plates are both 66 in the flow direction (MD) and 8.6 in the vertical direction (TD).

  Further, the support plate according to the fifth embodiment is provided with a protruding piece on the upper side, and this protruding piece is provided between the inner flaps of the outer box, and swinging in the rotation direction θ is restricted. In addition, the holding part was formed in this protrusion piece by providing opening.

  In Comparative Example 1, a film wound body was formed by winding a PET film having a thickness of 38 μm. The winding length is 1000 m. In Comparative Example 1, the support plate and the fixed cap were not used, and the reel flange was sandwiched by a pair of protectors via a cushion material, as in the conventional case. Furthermore, in Comparative Example 1, the size of the storage space of the outer box is slightly wider than the maximum width of the storage body, and a gap for inserting a finger when taking out the storage body from the outer box is secured (see FIG. 10).

  In the comparative example 2, it was set as the same conditions as the comparative example 1 except the point which used the conductive adhesive film (SP104A1) by Dexerials Corporation as a film wound by a film winding body. Since the film winding body according to Comparative Example 2 winds the conductive adhesive film, it was wound with a lower tension than Comparative Example 1.

  In Comparative Example 3, a conductive adhesive film (SP104A1) manufactured by Dexerials Co., Ltd. was used as the film wound around the film winding body, and the film winding body was used as the support plate and the same as in Examples 1-5. Clamped by a fixed cap. Further, in Comparative Example 3, the width (maximum width of the storage body) W1 between the locking portion outer surfaces of the fixed cap is 147 mm, and the width W2 of the storage space of the outer box is 152 mm. That is, in Comparative Example 3, the size of the storage space of the outer box is slightly wider than the maximum width of the film winding body that is a stored item.

  In Comparative Example 3, the outer box and the support plate are formed of the same material, and the elastic modulus of the outer box and the elastic modulus of the pair of support plates are both 66 in the flow direction (MD: Machine Direction) and the vertical direction ( TD: Transverse Direction) is 8.6. In Comparative Example 3, no protruding piece is formed on the support plate.

  The following drop test and vibration test were carried out on the samples of the film packages according to Examples 1 to 5 and Comparative Examples 1 to 3. The drop test complied with JIS Z0200 Package Cargo Evaluation Test General Rules. The condition is level II (because it is 10 kg or less, it drops from a height of 60 cm). In the vibration test, the acceleration power spectral density data of Annex a is recorded for 1 minute in accordance with JIS Z0232 (Packaging cargo vibration test method) test method 7.1.1 (random vibration test) on the pallet on which each sample is placed. The vibration reproduced in the random vibration waveform was carried out in the XYZ directions for 30 minutes each.

  The amount of winding deviation was measured after the drop test and after the vibration test. The amount of winding deviation was determined by measuring the length of the film wound around the core in the width direction of the film winding body with a SUS scale. As a result of measurement, when the amount of winding deviation is less than 2 mm, ◎ when 2 mm or more and less than 4 mm, △ when 4 mm or more and less than 8 mm, Δ when 8 mm or more and less than 12 mm, and × when 12 mm or more. did. Among these, a practical level is less than 12 mm (（to ΔΔ).

  Moreover, about the sample of each film package, the operation time which takes out a storage body from an outer box was measured. The results are shown in Table 1.

  As shown in Table 1, in Examples 1 to 5, the width W1 between the outer surfaces of the locking cap engaging portions is longer than the width W2 of the storage space of the outer box, so that the storage body is stored in the outer box. As a result, the storage body is pressed by the stress in the width W1 direction of the storage body generated in the outer box, thereby preventing the film winding body from swinging inside the outer box even after a drop test or a vibration test. The film winding deviation was less than 12 mm.

  In particular, in Example 1, since the PET film was wound with a high tension, the winding deviation after the drop test was less than 2 mm, and the winding deviation after the vibration test was as good as 2 mm or more and less than 4 mm. Moreover, in Example 1, since the protrusion piece was provided in the support plate and the holding part was provided in the protrusion piece, the work time which takes out a storage body from an outer box was as short as 2-3 seconds.

  Also in Example 2 in which the conductive adhesive film is wound, after the drop test and after the vibration test, the winding deviation is 2 mm or more and less than 4 mm, and the work time for taking out the storage body from the outer box is 2 to 2. It was as short as 3 seconds.

  In Example 3, since the elastic modulus of the support plate and the elastic modulus of the outer box were made the same, the function of suppressing vibration was slightly reduced, but the winding deviation after the drop test and after the vibration test was 4 mm or more and less than 8 mm. And it was good. In Example 3, since the protruding piece and the grip portion were not provided, the operation time for taking out the storage body from the outer box was as long as 7 to 10 seconds. This shows that it is more effective to make the elastic modulus of the support plate larger than the elastic modulus of the outer box.

  In Example 4, since the protruding piece and the grip portion were not provided, the work time for taking out the storage body from the outer box was increased to 7 to 10 seconds, but the winding deviation after the drop test was 4 mm or more and less than 8 mm, vibration test The subsequent winding deviation was as good as 2 mm or more and less than 4 mm.

  In Example 5, the width between the outer surfaces of the locking portion of the fixed cap (maximum width of the storage body) W1 and the width W2 of the storage space of the outer box are both the same (147 mm), and the elastic modulus of the outer box, The elastic modulus of the pair of support plates was 66 in the flow direction (MD: Machine Direction) and 8.6 in the vertical direction (TD: Transverse Direction). The winding deviation after the vibration test was as good as 4 mm or more and less than 8 mm. Moreover, in Example 5, since the protrusion piece was provided in the support plate and the holding part was provided in the protrusion piece, the work time which takes out a storage body from an outer box was as short as 2-3 seconds.

  On the other hand, in Comparative Example 1, since a PET film was wound, a relatively high tension could be applied, and the winding deviation after the drop test and after the vibration test was 4 mm or more and less than 8 mm. However, in Comparative Example 1, the time for taking out the storage body from the outer box was as long as 7 to 10 seconds. Comparing Comparative Example 1 and Example 1, when the storage body is stored in the outer box by setting the width W1 between the outer surfaces of the locking portion of the fixed cap to be longer than the width W2 of the storage space of the outer box. It can be seen that the film winding body can be pressed by the stress in the width W1 direction of the storage body generated in the outer box, and the winding deviation can be suppressed by dropping or vibration.

  In Comparative Example 2, since a conductive adhesive film was wound, high tension could not be applied, and winding deviation was 8 mm or more and 12 mm. Moreover, in the comparative example 2, the time which takes out a storage body from an outer box became long with 7 to 10 second. Comparing Comparative Example 2 with Example 3 and Example 5, even in the film winding body of the conductive adhesive film wound with a low tension, the width W1 between the outer surfaces of the locking portion of the fixed cap is By setting the length of the storage space to a width W2 or more, when the storage body is stored in the outer box, the film winding body is pressed by the stress in the width W1 direction of the storage body generated in the outer box, and it is wound by dropping or vibration. It can be seen that the deviation can be suppressed.

  Further, in Comparative Example 3, the size of the storage space of the outer box is slightly wider than the maximum width of the film wound body that is the stored item, so that there is a winding deviation of 12 mm or more after the drop test and after the vibration test. Occurred. Moreover, since the comparative example 3 did not form the protrusion piece and the holding part on the support plate, the time to take out the storage body from the outer box was as long as 7 to 10 seconds.

  In addition, from Examples 1, 2, and 5, it can be seen that by providing a protruding piece on the support plate and providing a gripping portion on the protruding piece, the operation time for taking out the storage body from the outer box can be greatly shortened.
