[0039] (Structure of Winding Device 100)

[0040] Figure 1 and Figure 2 It is a perspective view of the external appearance of a winding device 100 according to one embodiment. Figure 3 It is a side view of the winding device 100 according to one embodiment. Figure 4This is a side view of the winding device 100 according to one embodiment (a state in which the thread-like adhesive body 30 is threaded).

[0041] Figure 1 to Figure 4 The winding device 100 shown is a winding device 100 for winding the thread-like adhesive body 30 onto the outer peripheral surface 10A of the linear workpiece 10 .

[0042] Here, the linear workpiece 10 refers to all parts that can wind the filamentary adhesive body 30 on the outer peripheral surface 10A. The linear workpiece 10, for example, includes electric wires such as electric wires, cables, wire harnesses, handles of motorcycles, bicycles, etc., handles of golf clubs, fishing rods, tennis rackets, etc., cylinders, cylinders and parts with similar shapes. The linear workpiece 10 can be formed using hard materials to prevent elastic deformation, and can also be formed using materials with rubber elasticity in order to be able to deform elastically, and further, can also be formed using soft materials that can be plastically deformed. In addition, as long as the filamentary adhesive body 30 can be wound on the outer peripheral surface 10A, the linear workpiece 10 can have any shape and structure, and it can also be described as "winding object", "wound body", etc.

[0043] In addition, the filamentous adhesive body 30 is constituted to have a linear (linear) core material and an adhesive layer covering the surface of the core material. As the core material, for example, resin, rubber, foam, inorganic fiber and a composite of these can be used. The adhesive layer is formed using an adhesive. As the adhesive, for example, acrylic adhesives, rubber adhesives, vinyl alkyl ether adhesives, silicone adhesives, polyester adhesives, polyamide adhesives, urethane adhesives, fluorine adhesives, epoxy adhesives, etc. can be cited.

[0044] like Figure 1 to Figure 4 As shown, the winding device 100 includes a bobbin stand 110 , a first guide roller 120 - 1 , a second guide roller 120 - 2 , and a cover 140 .

[0045] The bobbin 20 on which the filamentary adhesive 30 is wound can be rotatably held by the bobbin 110. The bobbin 110 has a rod-shaped shaft portion 111 with the left-right direction (Y-axis direction) as the axial direction. On the other hand, the bobbin 20 is a cylindrical member on which the filamentary adhesive 30 is wound on the outer peripheral surface 20A. The bobbin 20 can be rotatably held around the axis of the shaft portion 111 by inserting the shaft portion 111 into the cylinder of the bobbin 20.

[0046] The first guide roller 120-1 and the second guide roller 120-2 are arranged in series on the path of the filamentary adhesive body 30 between the linear workpiece 10 and the spool frame 110. The first guide roller 120-1 is arranged at the front side (X-axis positive side) and the lower side (Y-axis negative side) of the spool frame 110. The second guide roller 120-2 is arranged between the spool frame 110 and the linear workpiece 10. That is, the second guide roller 120-2 is arranged at the rear side (X-axis negative side) and the lower side (Y-axis negative side) of the first guide roller 120-1 and at the front side (X-axis positive side) of the linear workpiece 10.

[0047] The first guide roller 120-1 and the second guide roller 120-2 are wheel-shaped and have a shaft 121 in the center. The first guide roller 120-1 and the second guide roller 120-2 are arranged to be rotatable around the axis of the shaft 121. The first guide roller 120-1 and the second guide roller 120-2 are arranged so that the axial direction of the shaft 121 becomes the left-right direction (Y-axis direction). The first guide roller 120-1 and the second guide roller 120-2 have a groove 122 on the outer peripheral surface. The first guide roller 120-1 and the second guide roller 120-2 guide the filamentary adhesive 30 drawn out from the bobbin 110 by hanging the wire in the groove 122.

[0048] The first guide roller 120-1 applies tension to the filamentary adhesive 30 by hanging the filamentary adhesive 30 in the groove 122 on the outside (positive side of the X axis), and guides the extension direction of the filamentary adhesive 30 to the direction where the second guide roller 120-2 is located. The second guide roller 120-2 applies tension to the filamentary adhesive 30 by hanging the filamentary adhesive 30 in the groove 122 on the outside (negative side of the Z axis), and guides the extension direction of the filamentary adhesive 30 to the direction where the cover 140 is located. In addition, the first guide roller 120-1 and the second guide roller 120-2 are configured so that the middle position of the first guide roller 120-1 and the second guide roller 120-2 coincides with the middle position of the bobbin frame 110 in the left-right direction (Y axis direction).

[0049] In addition, the winding device 100 of one embodiment is provided with two guide rollers 120 - 1 and 120 - 2 on the path of the thread-like adhesive 30 , but the present invention is not limited thereto, and one or three or more guide rollers may be provided.

[0050] The cover 140 is disposed on the lower side (negative side of the Z axis) of the bobbin frame 110. The cover 140 is a plate-like component having a certain width in the left-right direction (Y axis direction). The cover 140 has a U-shape that is folded into an opening on the rear side (negative side of the X axis) when viewed from the side (Y axis direction). The cover 140 covers the outer side (upper side (positive side of the Z axis), lower side (negative side of the Z axis) and front side (positive side of the X axis)) of the outer peripheral surface 10A of the linear workpiece 10 by arranging the linear workpiece 10 in the space 140A surrounded by the cover 140. The cover 140 has a slit 141 that is cut into a straight line along the left-right direction (Y axis direction) at the front end (the end on the positive side of the X axis) and in the middle position in the up-down direction (Z axis direction). The cover 140 can introduce the filamentary adhesive 30 from the outside of the cover 140 to the inside of the cover 140 by passing the filamentary adhesive 30 through the slit 141, and can maintain the height position of the filamentary adhesive 30 introduced into the inside of the cover 140 at a certain height position.

[0051] (Steps of Winding Method Using Winding Device 100)

[0052] The winding device 100 having the structure described above, as Figure 4 As shown, the bobbin 20 with the filamentary adhesive 30 wound thereon is set on the bobbin frame 110 (bobbin setting process), and the filamentary adhesive 30 drawn out from the bobbin 20 to the front (positive direction of the X-axis) and the bottom (negative direction of the Z-axis) is hung in the groove 122 of the first guide roller 120-1 and the groove 122 of the second guide roller 120-2 (hanging process), and then the filamentary adhesive 30 is introduced into the space 140A surrounded by the cover 140 through the slit 141 of the cover 140 (introduction process), and the front end portion of the filamentary adhesive 30 is pasted on the outer peripheral surface 10A of the linear workpiece 10 (pasting process). Thus, the winding device 100 can implement the process of winding the filamentary adhesive 30 around the outer peripheral surface 10A of the linear workpiece 10 ( Figure 5 and Figure 6 The winding process shown).

[0053] (Operation of Winding Device 100)

[0054] Figure 5 Schematically shows the winding operation of the winding device 100 according to one embodiment. Figure 5 As shown, in a winding device 100 of one embodiment, by integrating a bobbin frame 110, a bobbin 20, a first guide roller 120-1 and a second guide roller 120-2 and rotating around the linear workpiece 10, the filamentary adhesive 30 can be wound on the outer peripheral surface 10A of the linear workpiece 10.

[0055] Here, in the winding device 100, each component (the bobbin frame 110, the first guide roller 120-1, the second guide roller 120-2, and the cover 140) is unitized to prevent the relative positional relationship of each component from changing. Therefore, the winding device 100 can rotate each component around the axis of the linear workpiece 10 by rotating the unit as a whole with the linear workpiece 10 as the center, and the filamentary adhesive 30 can be wound on the outer peripheral surface 10A of the linear workpiece 10 without changing the relative positional relationship of each component.

[0056] The winding device 100 includes a rotating mechanism (not shown) including a motor, gears, a drive belt, and the like, and the unit can be electrically rotated by the rotating mechanism.

[0057] For example, the operator can turn on the switch of the rotating mechanism to rotate the unit, thereby starting the process of winding the filamentary adhesive body 30 around the outer peripheral surface 10A of the linear workpiece 10. Also, the operator can turn off the switch of the rotating mechanism to stop the unit from rotating, thereby ending the process of winding the filamentary adhesive body 30 around the outer peripheral surface 10A of the linear workpiece 10.

[0058] Here, in the winding device 100, since the shaft 111 of the bobbin frame 110 can rotatably hold the bobbin 20, the filamentary adhesive 30 will be pulled by the linear workpiece 10 as the unit rotates, so that the filamentary adhesive 30 can be pulled out from the bobbin 20 while the bobbin 20 rotates around the shaft 111 of the bobbin frame 110.

[0059] Furthermore, the winding device 100 can guide the filamentary adhesive body 30 while applying appropriate tension to the filamentary adhesive body 30 by hanging the filamentary adhesive body 30 on the first guide roller 120 - 1 and the second guide roller 120 - 2 so as to reliably feed the filamentary adhesive body 30 to the linear workpiece 10 .

[0060] In particular, the winding device 100 can prevent the filamentary adhesive 30 from falling off the first guide roller 120-1 and the second guide roller 120-2 by hanging the filamentary adhesive 30 in the groove 122 of the first guide roller 120-1 and the groove 122 of the second guide roller 120-2, thereby guiding the filamentary adhesive 30 so that the filamentary adhesive 30 can be more reliably delivered to the linear workpiece 10.

[0061] Furthermore, in the winding device 100 , the first guide roller 120 - 1 and the second guide roller 120 - 2 are rotated about the shaft 121 as the filamentary adhesive 30 moves, so that the filamentary adhesive 30 can be smoothly fed to the linear workpiece 10 .

[0062] In addition, the winding device 100 may also include a delivery mechanism including a motor, a gear, a drive belt, etc., and the delivery mechanism may electrically deliver the linear workpiece 10 along the axial direction (Y-axis direction) of the linear workpiece 10. Alternatively, the linear workpiece 10 may be manually delivered along the axial direction (Y-axis direction) of the linear workpiece 10 by an operator.

[0063] Thus, in the winding device 100, the filamentary adhesive 30 is wound on the outer peripheral surface 10A of the linear workpiece 10 while feeding the linear workpiece 10 at a certain speed along the axial direction of the linear workpiece 10, so that the filamentary adhesive 30 can be wound on the outer peripheral surface 10A of the linear workpiece 10 at a certain interval.

[0064] (Modification of the Operation of the Winding Device 100)

[0065] Figure 6 FIG. 1 is a diagram schematically showing a modified example of the winding operation of the winding device 100 according to one embodiment. Figure 6 As shown, a winding device 100 - 2 according to a modified example can wind the filamentary adhesive 30 onto the outer peripheral surface 10A of the linear workpiece 10 by rotating the linear workpiece 10 around the axis of the linear workpiece 10 .

[0066] In this case, the winding device 100 - 2 may include a rotating mechanism (not shown) including, for example, a motor, gears, a drive belt, etc., by which the linear workpiece 10 can be electrically rotated around the axis of the linear workpiece 10 .

[0067] For example, the operator can start the process of winding the filamentary adhesive 30 around the outer peripheral surface 10A of the linear workpiece 10 by turning on the switch of the rotating mechanism to rotate the linear workpiece 10. Furthermore, the operator can end the process of winding the filamentary adhesive 30 around the outer peripheral surface 10A of the linear workpiece 10 by turning off the switch of the rotating mechanism to stop the rotation of the linear workpiece 10.

[0068] Here, in the winding device 100-2, since the shaft 111 of the bobbin stand 110 can rotatably hold the bobbin 20, the filamentary adhesive 30 is pulled by the linear workpiece 10 as the linear workpiece 10 rotates, so that the filamentary adhesive 30 can be pulled out from the bobbin 20 while the bobbin 20 rotates around the shaft 111 of the bobbin stand 110 as the center.

[0069] Furthermore, the winding device 100 - 2 can guide the filamentary adhesive body 30 while applying appropriate tension to the filamentary adhesive body 30 by hanging the filamentary adhesive body 30 on the first guide roller 120 - 1 and the second guide roller 120 - 2 so as to reliably feed the filamentary adhesive body 30 to the linear workpiece 10 .

[0070] In particular, in the winding device 100-2, by hanging the filamentary adhesive 30 in the groove portion 122 of the first guide roller 120-1 and the groove portion 122 of the second guide roller 120-2, the filamentary adhesive 30 can be prevented from falling off the first guide roller 120-1 and the second guide roller 120-2, thereby guiding the filamentary adhesive 30 so that the filamentary adhesive 30 can be more reliably delivered to the linear workpiece 10.

[0071] In the winding device 100 - 2 , as the filamentary adhesive 30 moves, the first guide roller 120 - 1 and the second guide roller 120 - 2 rotate around the shaft 121 , thereby smoothly feeding the filamentary adhesive 30 to the linear workpiece 10 .

[0072] In addition, the winding device 100-2 may also include a delivery mechanism composed of a motor, a gear, a drive belt, etc., by which the linear workpiece 10 can be electrically delivered along the axial direction (Y-axis direction) of the linear workpiece 10. In addition, the linear workpiece 10 can also be manually delivered along the axial direction (Y-axis direction) of the linear workpiece 10 by an operator. Thus, the winding device 100-2 can wind the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10 at a certain interval while delivering the linear workpiece 10 along the axial direction of the linear workpiece 10 at a certain speed.

[0073] (An example of guide roller 120)

[0074] Figure 7 to Figure 10 1 is a diagram showing an example (first to fourth examples) of the guide rollers 120 provided in the winding device 100 according to one embodiment. For example, in the winding device 100 according to one embodiment, as the first guide roller 120-1 and the second guide roller 120-2, Figure 7 to Figure 10 Any of the guide rollers 120A to 120D shown.

[0075] Figure 7 to Figure 10 The guide rollers 120A to 120D shown are all wheel-shaped with a certain thickness and have a groove 122 on the outer peripheral surface. In addition, they have in common that the groove 122 has edges 123 with the largest diameter on both outer sides, but the shapes of the grooves 122 are different from each other.

[0076] For example, Figure 7 In the guide roller 120A shown, the cross-sectional shape of the groove portion 122 has a V-shape with an angle of 60°.

[0077] according to Figure 7As long as the angle of entry of the filamentary adhesive 30 relative to the groove 122 is within the range of 60°, the filamentary adhesive 30 will not be caught on the edge 123 even when the inclination angle of the guide roller 120A is fixed, and the filamentary adhesive 30 can be easily guided to the bottom of the valley of the groove 122 (i.e., the center position in the thickness direction). Figure 7 The guide roller 120A shown in FIG. 1 is provided with a winding width W1 (see FIG. 1 ) of the filamentary adhesive body 30 relative to the bobbin 20. Fig.11 and Figure 12) are smaller.

[0078] In addition, for example, Figure 8 In the guide roller 120B shown, the cross-sectional shape of the groove portion 122 has a V-shape with an angle of 90°.

[0079] according to Figure 8 As long as the angle of entry of the filamentary adhesive 30 relative to the groove 122 is within the range of 90°, the filamentary adhesive 30 will not be caught on the edge 123 even when the inclination angle of the guide roller 120B is fixed, and the filamentary adhesive 30 can be easily guided to the bottom of the valley of the groove 122 (i.e., the center position in the thickness direction). Figure 8 The guide roller 120B shown is effective when the winding width W1 of the filamentary adhesive 30 with respect to the bobbin 20 is large.

[0080] In addition, for example, Fig. 9 In the guide roller 120C shown, the cross-sectional shape of the groove portion 122 has a U-shape whose bottom portion is divided into a curved surface.

[0081] according to Fig. 9 As for the guide roller 120C shown, as long as the entry angle of the filamentary adhesive 30 relative to the groove portion 122 is within a relatively small angle range (i.e., the winding width W1 of the filamentary adhesive 30 is smaller than that of the bobbin 20), even when the inclination angle of the guide roller 120C is fixed, the filamentary adhesive 30 will not be caught on the edge portion 123, but can be guided to the curved bottom of the groove portion 122 (i.e., the center position in the thickness direction).

[0082] In addition, for example, Fig.10 In the guide roller 120D shown, the cross-sectional shape of the groove portion 122 has a concave shape in which the bottom portion is divided into a flat shape.

[0083] according to Fig.10The guide roller 120D shown, as long as the entry angle of the filamentary adhesive 30 relative to the groove portion 122 is within a relatively small angle range (that is, if the winding width W1 of the filamentary adhesive 30 relative to the bobbin 20 is relatively small), even when the inclination angle of the guide roller 120D is fixed, the filamentary adhesive 30 will not be caught on the edge portion 123, but can be guided to the planar bottom of the groove portion 122 (that is, the center position in the thickness direction).

[0084] but, Figures 7-10 The guide rollers 120A to 120D shown are as described later with reference to FIG. 12 . By setting the inclination angle of these guide rollers 120A to 120D to be variable, even when the entry angle of the filamentary adhesive 30 relative to the groove portion 122 is large (that is, when the winding width W1 of the filamentary adhesive 30 is large relative to the bobbin 20), the filamentary adhesive 30 will not be caught on the edge portion 123, and the filamentary adhesive 30 can be more reliably guided to the bottom of the groove portion 122.

[0085] in addition, Figures 7-10 The guide rollers 120A to 120D shown in the figure all have the groove portion 122 , and therefore the thread-like adhesive body 30 hung in the groove portion 122 is unlikely to fall out of the groove portion 122 .

[0086] in addition, Figures 7-10 The surfaces of the grooves 122 of the guide rollers 120A to 120D shown are all subjected to a non-adhesive treatment, and the filamentary adhesive 30 is difficult to adhere to the surface of the grooves 122. Therefore, the filamentary adhesive 30 hanging in the grooves 122 can be fed out with a low load.

[0087] The surface of the groove portion 122 is, for example, composed of at least one of fluororesin, silicone resin and polyolefin resin. Alternatively, the surface of the groove portion 122 is subjected to a non-adhesive treatment using, for example, at least one of a fluororesin coating, a silicone coating, a long-chain alkyl coating and a Tosical (registered trademark) coating. In addition, the treatment using the fluororesin coating includes the treatment using a fluororesin heat shrink tube or a fluororesin fabric sheet. Alternatively, the surface of the groove portion 122 may also be subjected to various non-adhesive treatments on the substrate. For example, concavities and convexities may be formed on the substrate by sandblasting, and a non-adhesive material may be coated on the concave portion, or the treatment may be performed by a PEEK (polyetheretherketone) coating, a fluorine-composite electroless nickel plating (eutectoid fluororesin particles are dispersed in the electroless nickel plating film), a dual ceramic (a fluororesin coating containing micronized ceramic particles), an FRP (Fiber Reinforced Plastics) lining, an ultra-high molecular PE (polyester) lining, etc.

[0088] also, Figures 7-10The guide rollers 120A to 120D shown may also have a "reflected portion" bent at a right angle or an acute angle inward (toward the groove 122) at the outer peripheral edge of the side 123. Figures 7-10 The guide rollers 120A to 120D shown can make it more difficult for the thread-like adhesive 30 to fall out of the groove portion 122 .

[0089] (Example of the feeding operation of the thread-like adhesive body 30 (first example))

[0090] Fig.11 This is a diagram showing an example (first example) of the feeding operation of the thread-like adhesive body 30 in the winding device 100 according to one embodiment. Fig.11 , an example of the feeding action of the filamentary adhesive body 30 is shown when the inclination angle of the first guide roller 120-1 is fixed. Fig.11 In the embodiment, as the first guide roller 120-1, use Figure 7 Guide roller 120A is shown.

[0091] like Fig.11 As shown, in one embodiment of the winding device 100, the first guide roller 120-1 and the bobbin 20 are configured so that the center position of the first guide roller 120-1 in the left-right direction (Y-axis direction) is consistent with the center position of the bobbin 20 in the left-right direction (Y-axis direction).

[0092] In addition, if Fig.11 As shown, in the winding device 100 according to one embodiment, the first guide roller 120 - 1 has the groove 122 , so the filamentary adhesive 30 hung in the groove 122 of the first guide roller 120 - 1 is unlikely to fall out of the groove 122 of the first guide roller 120 - 1 .

[0093] In addition, in one embodiment of the winding device 100, the surface of the groove portion 122 of the first guide roller 120-1 is non-adhesive, and the filamentary adhesive 30 is difficult to adhere to the surface of the groove portion 122 of the first guide roller 120-1, so the first guide roller 120-1 can deliver the filamentary adhesive 30 with a low load.

[0094] Here, Fig.11 In the illustrated example, the inclination angle of the first guide roller 120 - 1 is fixed to 0° (ie, an angle perpendicular to the outer peripheral surface 20A of the bobbin 20 ).

[0095] And, if Fig.11 As shown, the thread-like adhesive body 30 is wound on the outer peripheral surface 20A of the bobbin 20 with a winding width W1 in the left-right direction (Y-axis direction). Fig.11 As shown, the angle at which the filamentary adhesive 30 enters the groove 122 of the first guide roller 120 - 1 varies within an angle range determined according to the winding width W1 .

[0096] However, in Fig.11 In the example shown, the cross-sectional shape of the groove portion 122 of the first guide roller 120-1 has a V-shape with an angle of 60°. Fig.11 In the example shown, the angle at which the filamentous adhesive 30 enters the groove 122 falls within the range of 60° formed by the groove 122 .

[0097] Therefore, in Fig.11 In the example shown, even if the entry angle of the filamentary adhesive 30 relative to the groove 122 of the first guide roller 120-1 changes, the filamentary adhesive 30 will not be caught on the edge 123 of the first guide roller 120-1, and the filamentary adhesive 30 can be more reliably guided to the bottom of the groove 122.

[0098] (An example of the feeding operation of the thread-like adhesive body 30 (the second example))

[0099] Fig. 12A and Fig. 12B This is a diagram showing an example (second example) of the feeding operation of the thread-like adhesive body 30 in the winding device 100 according to one embodiment. Fig. 12A and Fig. 12B , an example of the feeding action of the filamentary adhesive body 30 is shown when the inclination angle of the first guide roller 120-1 is variable. Fig. 12A and Fig. 12B In the embodiment, as the first guide roller 120-1, a Figure 7 Guide roller 120A is shown.

[0100] like Fig. 12A and Fig. 12B As shown, in one embodiment of the winding device 100, the first guide roller 120-1 and the bobbin 20 are configured so that the center position of the first guide roller 120-1 in the left-right direction (Y-axis direction) is consistent with the center position of the bobbin 20 in the left-right direction (Y-axis direction).

[0101] 12 , in the winding device 100 according to the embodiment, the first guide roller 120 - 1 has a groove 122 , so that the filamentary adhesive 30 hung in the groove 122 of the first guide roller 120 - 1 is unlikely to fall off from the groove 122 of the first guide roller 120 - 1 .

[0102] In addition, in one embodiment of the winding device 100, the surface of the groove portion 122 of the first guide roller 120-1 is subjected to non-adhesive treatment, and the filamentary adhesive 30 is difficult to adhere to the surface of the groove portion 122 of the first guide roller 120-1, so the first guide roller 120-1 can deliver the filamentary adhesive 30 with a low load.

[0103] Here, in Fig. 12A and Fig. 12B In the example shown, the first guide roller 120-1 is configured so that the inclination angle of the first guide roller 120-1 relative to the outer peripheral surface 20A of the bobbin 20 can be changed according to the entry angle of the thread-like adhesive 30 into the groove portion 122 of the first guide roller 120-1.

[0104] And, if Fig. 12A and Fig. 12B As shown, the thread-like adhesive body 30 is wound on the outer peripheral surface 20A of the bobbin 20 with a winding width W1 in the left-right direction (Y-axis direction). Fig. 12A and Fig. 12B As shown, the angle at which the filamentary adhesive 30 enters the groove 122 of the first guide roller 120-1 varies within an angle range determined by the winding width W1. Fig. 12A : represents the angle of entry of the filamentary adhesive 30 with respect to the groove 122 when the filamentary adhesive 30 is fed out from the right end (the end on the positive side of the Y axis) of the winding width W1. Fig. 12B 1 shows the angle at which the filament-like adhesive body 30 enters the groove portion 122 when the filament-like adhesive body 30 is fed out from the left end portion (the end portion on the negative side of the Y axis) of the winding width W1.

[0105] However, in Fig. 12A and Fig. 12B In the example shown, the inclination angle of the first guide roller 120-1 relative to the outer peripheral surface 20A of the bobbin 20 is changed to be approximately equal to the entry angle of the filamentary adhesive 30 relative to the groove portion 122 of the first guide roller 120-1 due to the force caused by the filamentary adhesive 30 entering the first guide roller 120-1 (i.e., generated by the entry angle of the filamentary adhesive 30).

[0106] Therefore, in Fig. 12A and Fig. 12B In the example shown, even if the entry angle of the filamentary adhesive 30 relative to the groove 122 of the first guide roller 120-1 changes, the filamentary adhesive 30 will not be caught on the edge 123 of the first guide roller 120-1, and the filamentary adhesive 30 can be more reliably guided to the bottom of the groove 122.

[0107] In addition, the first guide roller 120 - 1 may be configured to be switchable between a state in which the inclination angle is fixed and a state in which the inclination angle is variable.

[0108] (Example of Winding Operation of Thread-Form Adhesive Body 30 (First Example))

[0109] Fig.13 This is a diagram showing an example (first example) of the winding operation of the thread-like adhesive body 30 in the winding device 100 according to one embodiment. Fig.13 FIG. 2 shows an example of the winding operation of the filamentary adhesive body 30 when the inclination angle of the second guide roller 120-2 is fixed. Fig.13 In the process, it is used as the second guide roller 120-2 Figure 7 Guide roller 120A is shown.

[0110] like Fig.13 As shown, in one embodiment of the winding device 100, the second guide roller 120-2 and the linear workpiece 10 are configured so that the center position of the second guide roller 120-2 in the left-right direction (Y-axis direction) is consistent with the center position of the linear workpiece 10 in the left-right direction (Y-axis direction).

[0111] Thus, the winding device 100 according to one embodiment can reliably guide the filamentous adhesive 30 to the center position in the left-right direction (Y-axis direction) of the linear workpiece 10 by the second guide roller 120 - 2 .

[0112] In addition, if Fig.13 As shown, in the winding device 100 according to one embodiment, the second guide roller 120 - 2 has the groove 122 , so the filamentary adhesive 30 hung in the groove 122 of the second guide roller 120 - 2 is unlikely to fall out of the groove 122 of the second guide roller 120 - 2 .

[0113] In addition, in one embodiment of the winding device 100, the surface of the groove portion 122 of the second guide roller 120-2 is treated to be non-adhesive, and the filamentary adhesive 30 is difficult to adhere to the surface of the groove portion 122 of the second guide roller 120-2, so the second guide roller 120-2 can deliver the filamentary adhesive 30 with a low load.

[0114] like Fig.13 As shown, a winding device 100 according to one embodiment feeds the linear workpiece 10 in the right direction (positive direction of the Y axis) while winding the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10, thereby being able to wind the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10 at a certain interval.

[0115] Here, in Fig.13 In the illustrated example, the inclination angle of the second guide roller 120 - 2 is fixed to 0° (ie, an angle perpendicular to the outer peripheral surface 10A of the linear workpiece 10 ).

[0116] And, if Fig.13 As shown, the winding position of the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10 may be changed from the center position of the linear workpiece 10 in the left-right direction (Y-axis direction).

[0117] However, in Fig.13In the example shown, the cross-sectional shape of the groove portion 122 of the second guide roller 120-2 has a V-shape with an angle of 60°. Fig.13 In the example shown, the feeding angle of the filamentous adhesive 30 from the groove portion 122 falls within the range of 60° formed by the groove portion 122 .

[0118] Therefore, in Fig.13 In the example shown, even if the delivery angle of the filamentary adhesive 30 from the groove 122 of the second guide roller 120-2 changes, the filamentary adhesive 30 will not be caught on the edge 123 of the second guide roller 120-2, and the filamentary adhesive 30 can be more reliably guided to the outer peripheral surface 10A of the linear workpiece 10.

[0119] (An example of winding operation of the thread-like adhesive body 30 (second example))

[0120] Fig.14 This is a diagram showing an example (second example) of the winding operation of the thread-like adhesive body 30 in the winding device 100 according to one embodiment. Fig.14 FIG. 2 shows an example of the winding operation of the filamentary adhesive body 30 when the inclination angle of the second guide roller 120-2 is variable. Fig.14 In the process, it is used as the second guide roller 120-2 Figure 7 Guide roller 120A is shown.

[0121] like Fig.14 As shown, in one embodiment of the winding device 100, the second guide roller 120-2 and the linear workpiece 10 are configured so that the center position of the second guide roller 120-2 in the left-right direction (Y-axis direction) is consistent with the center position of the linear workpiece 10 in the left-right direction (Y-axis direction).

[0122] Thus, the winding device 100 according to one embodiment can reliably guide the filamentary adhesive 30 to the center position of the linear workpiece 10 in the left-right direction (Y-axis direction) by the second guide roller 120 - 2 .

[0123] In addition, if Fig.14 As shown, in the winding device 100 according to one embodiment, the second guide roller 120 - 2 has the groove 122 , so the filamentary adhesive 30 hung in the groove 122 of the second guide roller 120 - 2 is unlikely to fall out of the groove 122 of the second guide roller 120 - 2 .

[0124] In addition, in one embodiment of the winding device 100, the surface of the groove portion 122 of the second guide roller 120-2 is subjected to non-adhesive treatment, and the filamentous adhesive 30 is difficult to adhere to the surface of the groove portion 122 of the second guide roller 120-2, so the second guide roller 120-2 can deliver the filamentous adhesive 30 with a low load.

[0125] like Fig.14 As shown, a winding device 100 according to one embodiment feeds the linear workpiece 10 in the right direction (positive direction of the Y axis) while winding the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10, thereby being able to wind the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10 at a certain interval.

[0126] Here, in Fig.14 In the example shown, the second guide roller 120 - 2 is arranged so that the inclination angle of the second guide roller 120 - 2 relative to the outer peripheral surface 10A of the linear workpiece 10 can be changed according to the angle at which the filamentary adhesive 30 is fed out of the groove 122 of the second guide roller 120 - 2 .

[0127] And, if Fig.14 As shown, the winding position of the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10 may be changed from the center position of the linear workpiece 10 in the left-right direction (Y-axis direction).

[0128] However, in Fig.14 In the example shown, the inclination angle of the second guide roller 120-2 relative to the outer peripheral surface 10A of the linear workpiece 10 is affected by the force of the filamentary adhesive 30 sent out from the second guide roller 120-2 (i.e., the force generated by the sending angle of the filamentary adhesive 30), and changes to be approximately equal to the sending angle of the filamentary adhesive 30 relative to the groove portion 122 of the second guide roller 120-2.

[0129] Therefore, in Fig.14 In the example shown, even if the delivery angle of the filamentary adhesive 30 from the groove portion 122 of the second guide roller 120-2 changes, the filamentary adhesive 30 will not be caught on the edge portion 123 of the second guide roller 120-2, and the filamentary adhesive 30 can be more reliably guided to the outer peripheral surface 10A of the linear workpiece 10.

[0130] In addition, the second guide roller 120 - 2 may be configured to be switchable between a state in which the inclination angle is fixed and a state in which the inclination angle is variable.

[0131] (Braking mechanism 150)

[0132] Fig.15A and Fig. 15B FIG. 1 is a diagram showing an example of a brake mechanism 150 provided in a winding device 100 according to an embodiment. Fig.15A and Fig. 15B As shown, the winding device 100 according to one embodiment may include a brake mechanism 150 for braking the rotation of the spool 20 .

[0133] exist Fig.15A and Fig. 15BIn the example shown, the brake mechanism 150 is provided at the right end portion (the positive end on the Y axis) of the bobbin 20 .

[0134] For example, the brake mechanism 150 may be a mechanical brake (eg, a slip & clutch brake, etc.) that brakes the rotation of the spool 20 by applying a friction force to the spool 20 or the spool stand 110 .

[0135] Furthermore, for example, the brake mechanism 150 may be an electromagnetic brake (eg, a powder brake) that brakes the rotation of the spool 20 by applying an electromagnetic force to the spool 20 or the creel stand 110 .

[0136] The winding device 100 according to one embodiment includes the brake mechanism 150 and controls the braking force applied by the brake mechanism 150 to the rotation of the bobbin 20 (ie, controls the rotation load of the bobbin 20 ), thereby being able to control the tension of the filamentary adhesive 30 fed from the bobbin 20 to a constant tension.

[0137] In particular, in the winding device 100 of one embodiment, since the tension of the filamentary adhesive 30 fed from the bobbin 20 is difficult to be constant due to the bonding effect between the filamentary adhesive 30 wound on the bobbin 20, it is effective to provide a brake mechanism 150 to control the tension of the filamentary adhesive 30 fed from the bobbin 20 to be constant. Thus, the winding device 100 of one embodiment can wind the filamentary adhesive 30 on the outer peripheral surface 10A of the linear workpiece 10 at an arbitrary pressure.

[0138] (Effect)

[0139] As described above, a winding device 100 according to one embodiment is a winding device 100 for winding a filamentary adhesive 30 onto the outer peripheral surface 10A of a linear workpiece 10, and includes: a bobbin frame 110 for rotatably holding a bobbin 20 on which the filamentary adhesive 30 is wound; a guide roller 120, which is arranged on the path of the filamentary adhesive 30 between the linear workpiece 10 and the bobbin frame 110, and has a groove 122 on the outer peripheral surface, and the filamentary adhesive 30 drawn out from the bobbin 20 is hung in the groove 122, and the bobbin frame 110 and the guide roller 120 are integrally formed and rotated around the linear workpiece 10, thereby winding the filamentary adhesive 30 onto the outer peripheral surface 10A of the linear workpiece 10.

[0140] Thus, the winding device 100 according to one embodiment can easily and reliably wind the thread-like adhesive 30 onto the outer peripheral surface 10A of the linear workpiece 10 simply by rotating around the linear workpiece 10 .

[0141] In addition, the winding device 100 according to one embodiment can more reliably guide the thread-like adhesive body 30 drawn out from the bobbin 20 to the outer peripheral surface 10A of the linear workpiece 10 by the guide roller 120 .

[0142] Furthermore, the winding device 100 according to one embodiment has the groove 122 in the guide roller 120 , and can more reliably guide the filamentary adhesive 30 drawn out from the bobbin 20 to the outer peripheral surface 10A of the linear workpiece 10 without the guide roller 120 falling off the groove 122 .

[0143] In addition, a winding device 100-2 according to one embodiment is a winding device 100-2 for winding a filamentary adhesive 30 onto an outer peripheral surface 10A of a linear workpiece 10, and includes: a bobbin frame 110 for rotatably holding a bobbin 20 on which the filamentary adhesive 30 is wound; a guide roller 120, which is arranged on a path of the filamentary adhesive 30 between the linear workpiece 10 and the bobbin frame 110, and has a groove 122 on its outer peripheral surface, and the filamentary adhesive 30 drawn out from the bobbin 20 is hung in the groove 122, and the linear workpiece 10 rotates around the axis of the linear workpiece 10, so that the filamentary adhesive 30 is wound onto the outer peripheral surface 10A of the linear workpiece 10.

[0144] Thus, the winding device 100 - 2 according to one embodiment can easily and reliably wind the filamentary adhesive 30 around the outer peripheral surface 10A of the linear workpiece 10 simply by rotating the linear workpiece 10 around the axis of the linear workpiece 10 .

[0145] In addition, the winding device 100 - 2 according to one embodiment can more reliably guide the thread-like adhesive body 30 drawn out from the bobbin 20 to the outer peripheral surface 10A of the linear workpiece 10 by the guide roller 120 .

[0146] In addition, the winding device 100 - 2 of one embodiment has the groove 122 in the guide roller 120 , and can more reliably guide the filamentary adhesive 30 drawn out from the bobbin 20 to the outer peripheral surface 10A of the linear workpiece 10 without causing the guide roller 120 to fall off from the groove 122 .

[0147] In the winding device 100 or 100 - 2 of one embodiment, the inclination of the guide roller 120 relative to the bobbin 20 may be changed according to the angle at which the thread-like adhesive 30 drawn out from the bobbin 20 enters the groove 122 .

[0148] Therefore, the winding device 100 or 100 - 2 according to the embodiment can more reliably hang the filamentary adhesive 30 drawn out from the bobbin 20 in the groove 122 of the guide roller 120 , and can prevent the filamentary adhesive 30 from falling out of the groove 122 .

[0149] In the winding device 100 or 100 - 2 according to one embodiment, the guide roller 120 may have a structure in which the surface of the groove portion 122 is subjected to a non-adhesive treatment.

[0150] Thus, the winding device 100, 100-2 of one embodiment can guide the filamentary adhesive 30 drawn out from the bobbin 20 by the guide roller 120 without adhering the filamentary adhesive 30 to the surface of the groove 122 of the guide roller 120 (that is, without applying a load to the feeding of the filamentary adhesive 30).

[0151] Furthermore, the winding device 100 or 100 - 2 according to one embodiment may include a brake mechanism 150 for braking the rotation of the spool 20 .

[0152] Therefore, the winding device 100, 100-2 of one embodiment can control the tension of the filamentary adhesive body 30 sent from the bobbin 20 by the brake mechanism 150 to a constant tension. Therefore, the winding device 100, 100-2 of one embodiment can easily and reliably wind the filamentary adhesive body 30 on the outer peripheral surface 10A of the linear workpiece 10 at an arbitrary pressure.

[0153] In the winding device 100 or 100 - 2 according to one embodiment, the bobbin holder 110 may rotatably hold the bobbin 20 on which the filamentary adhesive body 30 is not wound with a release sheet.

[0154] Thus, the winding device 100 or 100 - 2 according to one embodiment can easily and reliably wind the filamentary adhesive 30 onto the outer peripheral surface 10A of the linear workpiece 10 by simply pulling out the filamentary adhesive 30 from the bobbin 20 without performing a step of peeling off a release sheet from the filamentary adhesive 30 .

[0155] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to these embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims.

[0156] (Modification of the threading method of the filamentous adhesive body 30)

[0157] Fig.16 and Fig.17 It is a diagram showing a modification of the threading method of the filamentous adhesive body 30 in the winding device 100 according to one embodiment.

[0158] In the winding device 100, 100-2 of one embodiment, Figures 4 to 6 In the example shown, the thread-like adhesive body 30 is pulled out from the upper side (Z-axis positive side) of the spool 20, and the spool 20 is rotated in the clockwise direction when viewed from the right (Y-axis positive direction), but as another example, it is also possible to Fig.16As shown, the filamentary adhesive 30 is pulled out from the lower side (negative side of the Z axis) of the bobbin 20, so that the bobbin 20 rotates counterclockwise when viewed from the right (positive direction of the Y axis). Therefore, since the angle at which the filamentary adhesive 30 is held by the first guide roller 120-1 becomes larger, it is more difficult to make the filamentary adhesive 30 fall off from the first guide roller 120-1.

[0159] In addition, in the winding device 100, 100-2 of one embodiment, Figures 4 to 6 In the example shown, the spool 20 side is taken as the inner side, and the filamentous adhesive 30 is hung on the outer side of the first guide roller 120-1 and the outer side of the second guide roller 120-2. Fig.17 As shown, the filamentary adhesive 30 may also be hung on the outside of the first guide roller 120-1 and the inside of the second guide roller 120-2. That is, the filamentary adhesive 30 may also be hung on the first guide roller 120-1 and the second guide roller 120-2 in an S-shape. Thus, the filamentary adhesive 30 is less likely to fall off from the first guide roller 120-1 and the second guide roller 120-2.
