Description

【Technical Field】 【0001】 The present invention relates to a method for winding a carrier tape and a winding body. 【Background Art】 【0002】 Conventionally, a carrier tape having a storage recess capable of storing components is wound in multiple layers in a traverse winding (spiral winding) manner on a wide winding reel so as to be wound in a long length, and is stored, shipped, and transported in the state of a winding body (see Patent Document 1). 【0003】 As a winding method for winding such a carrier tape in a roll shape, an interlayer material such as a resin sheet or a paper sheet is arranged as a interleaving paper for photographic paper as if it overlaps the upper surface or the lower surface of the carrier tape, and is wound simultaneously (co-wound) (see Patent Document 2). In this winding method, by interposing an interlayer material between the storage recesses in the upper layer and the lower layer, the opening of the storage recess is closed or covered, and various problems such as the phenomenon of the upper layer falling into the gap between the lower layer rows, the phenomenon of the lower layer storage recess fitting into the upper layer storage recess due to the upper layer storage recess, and the winding step are prevented. 【0004】 However, since the interlayer material found in Patent Document 2 is sandwiched (held) between the carrier tapes only by the frictional force and the winding tension, the carrier tape winding body may move from the upper part of the opening of the storage recess to the side of the feed hole provided at the end due to vibrations and impacts during transportation, etc., and positional deviation may occur. 【0005】 Therefore, as disclosed in Patent Document 3, a structure in which a carrier tape and an interlayer material are bonded together by the adhesive force (tack) of a thermosensitive reaction type adhesive (adhesive) has also been proposed. Since the thermosensitive reaction type adhesive of this Patent Document 3 causes peeling at the interface when the interlayer material is peeled from the carrier tape, almost no adhesive (residue) remains on the carrier tape. 【Prior Art Documents】 【Patent Documents】 【0006】 [Patent Document 1] Japanese Patent Publication No. 2001-247158 [Patent Document 2] Japanese Patent Publication No. 2024-136381 [Patent Document 3] Japanese Patent Publication No. 2019-210019 [Overview of the Initiative] [Problems that the invention aims to solve] 【0007】 However, when bonding the carrier tape and interlayer material with a heat-sensitive adhesive, pressure and heating are applied, which can cause deformation or surface roughness in the carrier tape. As a result, when components are placed on such a carrier tape, the carrier tape may meander in the mounting machine, leading to component mounting defects. 【0008】 Therefore, the present invention has been made in view of the above problems, and aims to provide a method for winding a carrier tape and a winding body that can suppress misalignment of interlayer materials arranged between carrier tapes and suppress deformation of the carrier tape. [Means for solving the problem] 【0009】 (1) One aspect of the present invention is a method for winding a carrier tape having a storage recess, in which a carrier tape is wound into a roll shape with an interlayer material sandwiched between them, wherein the carrier tape and the interlayer material are bonded together with an adhesive layer and wound together, and the adhesive of the adhesive layer is an ultraviolet peelable type whose adhesive strength decreases when exposed to ultraviolet light. (2) In the embodiment of (1) above, the adhesive of the adhesive layer may have a peel strength of 12 mN / mm or more and 92 mN / mm or less before ultraviolet irradiation. (3) In the embodiment of (1) or (2) above, the adhesive of the adhesive layer may have a peel strength of 43 mN / mm or less after ultraviolet irradiation. (4) In any one embodiment of (1) to (3) above, the carrier tape may be wound spirally onto a take-up reel. (5) Another embodiment of the present invention is a winding of carrier tape having a storage recess, in which an interlayer material is sandwiched between a lower carrier tape and an upper carrier tape and wound into a roll, wherein the carrier tape and the interlayer material are bonded together by an adhesive layer, and the adhesive of the adhesive layer is an ultraviolet peelable type whose adhesive strength decreases when exposed to ultraviolet light. [Effects of the Invention] 【0010】 According to the present invention, it is possible to provide a method for winding a carrier tape and a winding body that can suppress misalignment of interlayer materials arranged between carrier tapes and suppress deformation of the carrier tape.

[Modes for carrying out the invention] 【0012】 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the embodiments of this specification, the same members are denoted by the same reference numerals throughout. 【0013】 FIG. 1A is a perspective view showing a carrier tape 10 and an interlayer material 20 according to an embodiment of the present invention, and is a cross-sectional view showing the interlayer material 20 according to an embodiment of the present invention. As shown in FIG. 1A, the carrier tape 10 has a plurality of feed holes 12 into which a sprocket (not shown) of a mounting device is inserted and storage recesses 13 capable of individually storing components such as electronic components, formed at predetermined intervals in the longitudinal direction. 【0014】 This carrier tape 10 is formed by processing a tape-shaped base material having a thickness of 0.2 mm to 0.6 mm. The tape-shaped base material is formed of, for example, synthetic resins such as polyvinyl chloride, polystyrene, amorphous polyethylene terephthalate, polycarbonate, polypropylene, those obtained by kneading carbon into these resins to impart conductivity, those having a conductive coating on the surface, and the like. The width of the carrier tape 10 is, for example, preferably about 8 mm to 56 mm. 【0015】 The feed holes 12 are circular in plan view, but the shape and interval of the feed holes 12 may be formed in accordance with a feed mechanism such as a sprocket. The diameter of the feed holes 12 is about 0.8 mm to 1.5 mm. Also, the feed holes 12 may be formed on both sides of the storage recess 13 along two sides in the longitudinal direction. 【0016】 On the other hand, the storage recess 13 is substantially rectangular, but is formed in accordance with the shape of the component to be stored, and a pedestal may be formed on the opening side of the bottom surface. The opening dimension of the storage recess 13 is, for example, preferably about 2 mm to 16 mm square, and the depth is preferably about 0.3 mm to 6 mm. 【0017】 Next, an outline of the winding method for the carrier tape 10 according to the embodiment of the present invention will be described. Figure 2 is a schematic diagram showing the state in which the carrier tape 10 is wound onto the winding reel 40 by the winding method for the carrier tape 10 according to the embodiment of the present invention. The winding method for the carrier tape 10 according to the embodiment of the present invention is the same as the conventional winding method for the carrier tape 10, except that the interlayer material 20, which will be described later, is adhered to the carrier tape 10 before winding. 【0018】 The winding method for the carrier tape 10 in the embodiment of the present invention involves traverse winding, in which the carrier tape 10 is wound spirally onto the winding reel 40. While the carrier tape 10 is wound onto the winding reel 40 in one rotation, the upstream wire entry guide roll (not shown) of the winding reel 40 is moved laterally at a predetermined lead pitch, from one side plate 41 of the winding reel 40 to the other side plate 41. 【0019】 In the standard winding configuration of traverse winding, the lead pitch of the wire entry guide roll, which traverses laterally, is set to repeat a state that is approximately equal to the width of the carrier tape 10. For example, if the total width of the carrier tape 10 is 8 mm and the width of the feed hole side flange is 3.1 mm, then in the first layer's rotation, the lead pitch of the wire entry guide roll is set to a range of 8.1 mm to 9.0 mm, and the tape is wound so that the flange on the opposite side of the feed hole 12 does not overlap with the feed hole side flange of the carrier tape 10 that has been wound up earlier. In this way, the carrier tape 10 is wound onto the core 42 of the winding reel 40 using the standard winding method for the first layer. 【0020】 Next, the traverse direction of the reel 40 is reversed near the left and right side plates 41 of the core 42. After the reversal, the lead pitch of the wire entry guide roll is set to a range of 8.1 mm to 9.0 mm, and the second layer is wound in such a way that the flange portion does not overlap with the feed hole side flange portion of the carrier tape 10 that was wound earlier. In this way, the second layer of the carrier tape 10 is also wound onto the reel 40 using the same winding method as the first layer. This process is then repeated for the required number of layers. 【0021】 The winding tension of the carrier tape 10 is managed by a tension controller (not shown), and the winding tension of the carrier tape 10 is adjusted by controlling the rotational speed of the winding reel 40 with the torque of a winding motor (not shown) controlled by a control unit (not shown). 【0022】 Furthermore, in the turn section near the side plate 41 of the winding reel 40, the relative traverse movement direction between the carrier tape 10 and the winding reel 40 is reversed, and the winding position of the lower carrier tape 10 is not stable. Therefore, when the carrier tape 10 is wound with high winding tension, the storage recess 13 of the upper carrier tape 10 deforms the flange portion on the feed hole side of the lower carrier tape 10, causing undulation and deformation of the carrier tape 10. 【0023】 Figure 3 is a cross-sectional view showing a winding body 30 and a winding reel 40 in which the carrier tape 10 and interlayer material 20 have been wound using the carrier tape 10 winding method according to an embodiment of the present invention. In this way, the carrier tape 10 and the interlayer material 20 are wound onto the winding reel 40, so that the interlayer material 20 is sandwiched between the lower carrier tape 10 and the upper carrier tape 10, forming a rolled body 30. 【0024】 Incidentally, the interlayer material 20 is a sheet (tape) made of synthetic resin or paper, which serves as the base layer 21. When a synthetic resin sheet is used as the interlayer material 20, thermoplastic resins such as polyolefin (PO), polyvinyl alcohol (PVA), polyethylene terephthalate (PET), polyvinyl chloride (PCB), polystyrene (PS), polycarbonate (PC), and polypropylene (PP) are preferred. In addition, resins to which carbon has been kneaded to impart conductivity, resins to which a conductive coating has been applied to the surface, or resins to which electrostatic properties have been imparted may also be used. 【0025】 Furthermore, among these synthetic resin sheets, polyolefins and polyvinyl alcohols are particularly preferred because they do not contain benzene rings in their chemical structure, making them less likely to absorb ultraviolet light. Note that if the base layer 21 of the interlayer material 20 is made of a material containing a structure that absorbs ultraviolet light, the curing reaction of the adhesive due to ultraviolet irradiation will be inhibited. However, this can be addressed by reducing the operating speed of the mounting machine and increasing the amount of ultraviolet irradiation (cumulative radiation). 【0026】 On the other hand, if a paper sheet is used as the interlayer material 20, for example, a basis weight of 20 g / m² is used. 2 ~100g / m 2 It can be used with a wide variety of papers, including general kraft paper, neutral kraft paper, dust-free paper, industrial mixed paper, unbleached wrapping paper, newspaper rolls, and specialty papers. 【0027】 Such interlayer material 20 is preferably thinner and has higher rigidity (bending rigidity) than the carrier tape 10 or the resin sheet substrate forming the carrier tape 10. For example, it should be about 20 μm to 100 μm thick, and preferably have a thickness of 10% to 200% of the thickness of the carrier tape 10. If the thickness of the interlayer material 20 is too thin, the rigidity of the sheet cannot be exerted, and conversely, if it is too thick, the rigidity of the sheet becomes too high, making it difficult to wind onto the winding reel 40. Note that "sheet" is used as a term meaning a thin substrate. 【0028】 The width of the interlayer material 20 can be selected from the same width as the carrier tape 10 to a width that covers at least a portion of the feed hole 12 or storage recess 13, depending on its position relative to the carrier tape 10 that it is wound with. Alternatively, the width of the interlayer material 20 may be greater than the width of the carrier tape 10, as seen in Patent Document 2. The specific arrangement of the interlayer material 20 relative to the carrier tape 10 will be described later. 【0029】 Furthermore, the interlayer material 20 has an adhesive layer 22 formed by an adhesive (tack) on one or both sides of the base layer 21, in part or all of it. As shown in Figures 1A and 1B, the interlayer material 20 of this embodiment does not block the opening of the feed hole 12 of the carrier tape 10, but covers the opening of the storage recess 13, and has adhesive layers 22 formed at both ends along the longitudinal direction. 【0030】 The adhesive for this bonding layer 22 should preferably be an UV-releasable type (easily peelable type) that hardens upon irradiation with ultraviolet light and has reduced peel strength. Examples of UV-releasable adhesives include acrylic resin-based adhesives containing a curing agent and a photoinitiator. 【0031】 The adhesive of the adhesive layer 22 should preferably have a peel strength (adhesion) of 12 mN / mm (20 g / 16 mm width) or more and 92 mN / mm (150 g / 16 mm width) or less before UV irradiation (initial), and more preferably 18 mN / mm (30 g / 16 mm width) or more and 92 mN / mm (150 g / 16 mm width) or less. Furthermore, the adhesive of the adhesive layer 22 should preferably have a peel strength of 43 mN / mm (70 g / 16 mm width) or less after UV irradiation, and more preferably 25 mN / mm (40 g / 16 mm width) or less. 【0032】 Therefore, the adhesive of the adhesive layer 22 should preferably have a peel strength of 45% to 70% of its initial peel strength after UV irradiation, and more preferably 50% to 65%. The peel strength of the adhesive of the adhesive layer 22 can be set by adjusting the content of the adhesive and hardener. 【0033】 The peel strength (adhesion) of the interlayer material 20 should be measured according to the "Test method for peel strength of cover tape" specified in "JIS C 0806-3:2014 7 (h), (i)". For example, the angle between the peeling direction of the interlayer material 20 and the carrier tape 10 should be set to 180 degrees, and the peeling speed should be set to 300 mm / min. Alternatively, the "Measurement of peel adhesion" specified in "JIS Z 0237 10.4" may be used instead. 【0034】 On the other hand, the ultraviolet irradiation source should emit light in the wavelength range of 315 nm to 400 nm. Suitable ultraviolet irradiation sources for this purpose include, for example, high-pressure mercury lamps, black lights, metal hide lamps, and UV-LEDs. Of these, black lights have low illumination and may require a long curing time, and metal hide lamps have high illumination and may cause thermal effects on the carrier tape 10 and interlayer material 20, so high-pressure mercury lamps are particularly preferred. The amount of ultraviolet irradiation should be set according to the adhesive of the adhesive layer 22. 【0035】 Next, different arrangement configurations of the interlayer material 20 relative to the carrier tape 10 will be explained based on modified configurations 1 and 2. Figure 4A is a perspective view showing the carrier tape 10 and interlayer material 20 of modified form 1 according to the present invention, and Figure 4B is a cross-sectional view of the interlayer material 20 of modified form 1 according to the present invention. Figure 5A is a perspective view showing the carrier tape 10 and interlayer material 20 of modified form 2 according to the present invention, and Figure 5B is a cross-sectional view of the interlayer material 20 of modified form 2 according to the present invention. 【0036】 The interlayer material 20 in modified form 1 does not block the opening of the feed hole 12 of the carrier tape 10, but covers the opening of the storage recess 13, and adhesive layers 22 are formed at both ends along the longitudinal direction. 【0037】 In modified form 2, the interlayer material 20 covers almost the entire surface of the carrier tape 10 so as to close the openings of the feed holes 12 and the storage recesses 13 of the carrier tape 10. In this case, the adhesive layer 22 is formed on almost the entire surface of the interlayer material 20, but as in the embodiment, the adhesive layer 22 may also be formed on both ends along the longitudinal direction of the interlayer material 20. 【0038】 However, the arrangement of the interlayer material 20 with respect to the carrier tape 10 is not limited to the configuration described above. It may also be used to cover the opening of the feed hole 12 of the carrier tape 10 from the front or back surface, or it may be bonded to the bottom surfaces of adjacent storage recesses 13. Furthermore, the adhesive layer 22 of the interlayer material 20 may be formed as a solid layer covering the entire surface of the interlayer material 20, or it may be formed in a dot pattern. Alternatively, the adhesive layer 22 may be formed continuously or intermittently along a portion of the longitudinal direction. 【0039】 Even with this arrangement of adhesive layers 22, just before the upper carrier tape 10 is wound onto the lower carrier tape 10 of the winding reel 40, the adhesive layer 22 of the interlayer material 20 is attached to the upper, lower, or both upper and lower carrier tapes 10, pressurized as necessary, and wound onto the winding reel 40 together with the carrier tape 10. 【0040】 Then, when inserting the component into the storage recess 13 of the carrier tape 10, the carrier tape 10 is unwound from the winding reel 40, and at the same time or afterward, ultraviolet light is irradiated onto the adhesive layer 22, and the carrier tape 10 is peeled away from the interlayer material 20 along with the hardened adhesive. After that, the component is inserted into the storage recess 13 of the carrier tape 10, the opening of the storage recess 13 is sealed with cover tape (not shown), and the tape is wound onto another small winding reel, completing the insertion of the component into the carrier tape 10. 【0041】 (Example of experiment) Finally, using interlayer material 20 to which adhesives having various properties were applied to the adhesive layer 22, in each experimental example, the interlayer material 20 was bonded so as to cover the storage recess 13 of the carrier tape 10 with a sheet width of 44 mm, and the winding state on the winding reel 40 was checked before and after transport. In addition, ultraviolet light was irradiated onto the carrier tape 10 and interlayer material 20 while they were wound on the winding reel 40, and then they were unwound to check the peelability of the interlayer material 20 from the carrier tape 10. 【0042】 The carrier tape 10 is made of polystyrene, with a sheet width of 44 mm and a thickness of 0.5 mm, and the storage recess 13 is 22 mm square and 22.1 mm deep. The base layer 21 of the interlayer material 20 is made of polyolefin and is 16 mm wide and 0.5 mm thick. The adhesive of the adhesive layer 22 has an initial peel strength of 147 mN to 1960 mN (15 g-weight to 200 g-weight) (per 16 mm width), as shown in Examples 1 to 3 and Comparative Examples 1 to 3. 【0043】 The results of each experiment are shown in Table 1 below. 【0044】 [Table 1] 【0045】 However, the defective (*1) could not be rewound from the take-up reel 40. The defective (*2) could not be easily peeled off the interlayer material 20 from the carrier tape 10. 【0046】 In Comparative Example 1, no winding collapse occurred before the transport of the winding reel 40, indicating that the adhesive strength between the carrier tape 10 and the interlayer material 20 was sufficient. However, due to vibrations and shocks during transport, winding collapse occurred after transport, indicating that the adhesive strength between the carrier tape 10 and the interlayer material 20 was not sufficient to withstand the vibrations and shocks during transport. In Comparative Examples 2 and 3, the adhesive strength between the carrier tape 10 and the interlayer material 20 was sufficient, and no winding collapse occurred before or after the transport of the winding reel 40. However, after UV irradiation, the peel strength of the adhesive layer 22 did not decrease sufficiently, resulting in poor peelability of the interlayer material 20. 【0047】 On the other hand, in Examples 1 to 3, the adhesive strength between the carrier tape 10 and the interlayer material 20 was sufficiently strong, so no winding collapse occurred on the winding reel 40 before and after transport. Furthermore, after UV irradiation, the peel strength of the adhesive layer 22 decreased sufficiently, resulting in good peelability of the interlayer material 20. Thus, in Examples 1 to 3, it was confirmed that the adhesive strength between the carrier tape 10 and the interlayer material 20 before UV irradiation and the peelability between the carrier tape 10 and the interlayer material 20 after UV irradiation were good. 【0048】 As described above, the winding method for the carrier tape 10 according to the embodiment of the present invention is a method for winding the carrier tape 10 having a storage recess 13 into a roll shape with an interlayer material 20 sandwiched in between, wherein the carrier tape 10 and the interlayer material 20 are bonded together with an adhesive layer 22 and wound up, and the adhesive of the adhesive layer 22 is an ultraviolet peelable type whose adhesive strength decreases when exposed to ultraviolet light. 【0049】 Furthermore, the carrier tape winding body 30 of the embodiment according to the present invention is a carrier tape winding body 30 having a storage recess 13, in which an interlayer material 20 is sandwiched between a lower carrier tape 10 and an upper carrier tape 10 and wound into a roll shape, wherein the carrier tape 10 and the interlayer material 20 are bonded together by an adhesive layer 22, and the adhesive of the adhesive layer 22 is an ultraviolet peelable type whose adhesive strength decreases when exposed to ultraviolet light. 【0050】 As a result, when the carrier tape 10 and interlayer material 20 are unwound from the winding reel 40, the adhesive layer 22 is irradiated with ultraviolet light, causing the adhesive in the adhesive layer 22 to harden, reducing the adhesive strength or peel strength, and making it easy to peel (separate) the interlayer material 20 from the carrier tape 10. In addition, when peeling the interlayer material 20 from the carrier tape 10, less adhesive residue is left on the carrier tape 10 side. 【0051】 Furthermore, it becomes less likely that the upper carrier tape 10 (especially the storage recess 13) will fall between the lower carrier tapes 10. Alternatively, by covering the opening of the storage recess 13 of the carrier tape 10 with the interlayer material 20, the storage recess 13 of the upper carrier tape 10 will not get stuck in the storage recess 13 of the lower carrier tape 10. In addition, the rigidity of the carrier tape 10 is increased by the rigidity of the interlayer material 20, which suppresses the occurrence of deformation or waviness near the turn of the carrier tape 10 wound on the winding reel 40. 【0052】 The adhesive of the adhesive layer 22 in this embodiment has a peel strength of 12 mN / mm or more and 92 mN / mm or less before UV irradiation. This stabilizes the adhesion between the upper or lower carrier tape 10 and the interlayer material 20, and prevents the relative positional relationship between the carrier tape 10 and the interlayer material 20 from shifting even after the carrier tape 10 is wound onto the winding reel 40. 【0053】 The adhesive in the adhesive layer 22 of this embodiment has a peel strength of 43 mN / mm or less after UV irradiation. As a result, when the carrier tape 10 and interlayer material 20 are unwound from the winding reel 40, UV irradiation of the adhesive layer 22 causes the adhesive in the adhesive layer 22 to harden, sufficiently reducing the adhesive strength or peel strength, and allowing the interlayer material 20 to be easily peeled (separated) from the carrier tape 10. 【0054】 In this embodiment, the carrier tape 10 is wound spirally onto the winding reel 40. This allows the carrier tape 10 to be wound onto the winding reel 40 in long lengths, such as 100m. 【0055】 Although preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the embodiments described above, and various modifications and changes are possible within the scope of the gist of the present invention as described in the claims. 【0056】 (modified version) In the above embodiment, the interlayer material 20 was attached to the carrier tape 10 by the adhesive layer 22 formed on the base layer 21 when it was wound onto the winding reel 40. However, the carrier tape 10 and the interlayer material 20 may be bonded together by directly supplying adhesive from a coating nozzle or the like just before the carrier tape 10 is wound onto the lower layer of the winding reel 40, without using the adhesive layer 22, that is, without forming the adhesive layer 22 on the base layer 21 in advance.
