<About tape winding jig>
First, the tape winding jig will be described. 1 is a perspective view showing the tape winding jig 20, FIG. 2 is a side view showing the internal structure of the jig main body 30 of the tape winding jig 20, and FIGS. It is explanatory drawing which shows the operation | movement which sets to the electric wire bundle.

  The tape winding jig 20 is for winding the tape 18 around a long member. Here, an electric wire bundle 10 in which electric wires are bundled is assumed as the long member. The electric wire bundle 10 is usually a part of a wire harness in which a plurality of electric wires are bundled while being appropriately branched. That is, as a wiring member in a vehicle or the like, a wire harness in which a plurality of electric wires are bundled while being branched according to a wiring route in the vehicle is used. The wire bundle 10 which is a part of the wire harness is bundled by winding the tape 18 in order to maintain a branching form corresponding to the wiring path. This tape winding jig 20 is used for winding the tape 18 around the electric wire bundle 10. The tape winding jig 20 is used not only for winding the tape 18 around the electric wire bundle 10 but also when winding the tape around a tube such as a corrugated tube sheathed on the electric wire, or when winding the tape around a bundle such as a tube. be able to.

  The tape winding jig 20 includes a jig main body 30 and a lid 50.

  The jig main body 30 is a member formed of resin, metal, or the like, and a setting recess 32 is formed on the outer periphery. The setting recess 32 extends in the thickness direction of the jig main body 30 (the thickness direction coincides with the axial direction of the tape winding body 16 supported by the tape winding body support portion 44). It is formed in a concave groove shape that is recessed in a U-shape. The setting recess 32 is set to a size that allows the electric wire bundle 10 to be wound around the tape 18 to be disposed. That is, the width dimension and depth dimension of the setting recess 32 are set to be equal to or larger than the outer diameter dimension of the wire bundle 10. Further, the setting recesses 32 are open on both sides of the jig body 30 in the thickness direction. For this reason, when the extending direction intermediate portion of the wire bundle 10 is disposed in the setting recess 32 in a posture in which the extending direction of the wire bundle 10 is aligned with the extending direction of the setting recess 32, the setting recess The both ends of the wire bundle 10 extend outward from the openings on both sides of 32.

  The lid portion 50 is a member formed of resin, metal, or the like. The lid portion 50 opens the jig body 30 to open the outer peripheral side opening of the setting concave portion 32 and closes the outer peripheral side opening of the setting concave portion 32. It is supported by posture change between postures. Here, the outer shape of the lid 50 is formed in a cylindrical shape. A lid-side recess 52 is formed on the outer periphery of the lid 50. The lid-side recess 52 is formed in a groove shape that is recessed in a C-shape or U-shape extending along the thickness direction of the lid 50. The lid side recess 52 is set to a size that allows the wire bundle 10 to be wound around the tape 18 to be disposed. That is, the width dimension and depth dimension of the lid-side recess 52 are set to be equal to or larger than the outer diameter dimension of the wire bundle 10. Here, the lid-side recess 52 is formed in the same size and shape as the setting recess 32. The lid-side recess 52 is set to a depth that does not reach the center of the lid 50.

  The lid portion 50 is rotatably supported on one side portion of the jig main body portion 30 on the outer peripheral side opening of the setting concave portion 32 via the shaft portion 34. When the jig main body 30 is viewed along the thickness direction, the lid 50 is rotated so that the setting concave portion 32 and the lid-side concave portion 52 coincide with each other. One side part of the outer peripheral side opening of the recessed part 52 will be in the state which closes the outer side opening of the recessed part 32 for a setting (refer FIG.1 and FIG.4). The said attitude | position of the cover part 50 is a closed attitude | position. Further, from this closed position, the lid 50 is rotated so that the outer peripheral side opening of the lid side concave portion 52 is positioned on the outer peripheral side of the jig main body 30 with respect to the outer opening of the setting concave portion 32. Then, when the jig main body 30 is viewed along the thickness direction, the outer opening of the setting recess 32 communicates with the outside through the lid recess 52 and the outer peripheral opening (see FIG. 4). ). For this reason, the wire bundle 10 is relatively pushed into the setting recess 32 through the outer peripheral side opening of the lid side recess 52, the internal space of the lid side recess 52, and the outer opening of the setting recess 32. Will be able to.

  Further, when the jig main body 30 is viewed in the thickness direction in the above open posture, the other side portion of the opening on the outer peripheral side of the lid-side recess 52 in the lid 50 is located in the setting recess 32. Yes. For this reason, when the electric wire bundle 10 is relatively pushed into the setting recess 32, the electric wire bundle 10 comes into contact with the other side portion of the outer peripheral side opening of the lid side recess 52 in the lid portion 50. From this state, when the electric wire bundle 10 is further pushed into the setting concave portion 32, the electric wire bundle 10 pushes the other side portion of the outer peripheral side opening of the lid side concave portion 52 of the lid portion 50, while setting the concave portion for setting. 32. Therefore, the position of the lid 50 can be changed from the open position to the closed position by the operation of relatively pushing the wire bundle 10 into the setting recess 32.

  When the lid 50 is in the closed position, the wire bundle 10 is surrounded by the setting recess 32 and the lid-side recess 52 when the jig main body 30 is viewed along its thickness direction. Can rotate relative to each other within the space surrounded by the set recess 32 and the lid-side recess 52. That is, the tape winding jig 20 including the jig main body 30 and the lid 50 rotates around the electric wire bundle 10 in a state where the electric wire bundle 10 is disposed in the setting concave portion 32 and the lid-side concave portion 52. Can do.

  In addition, when the wire bundle 10 is relatively moved toward the lid-side recess 52 in a state where the wire bundle 10 is disposed in the setting recess 32 and the lid-side recess 52, the wire bundle 10 is moved to the lid side. The concave portion 52 is pushed toward the outer peripheral side of the jig main body 30. Thereby, the attitude | position of the cover part 50 changes from a closed attitude | position to an open attitude | position, and the wire bundle 10 can be removed now from the recessed part 32 for a setting.

  That is, after forming a concave portion 52 including the same shape as the concave shape of the setting concave portion 32 in the lid portion 50, the lid portion 50 is closed with the concave portion 52 coinciding with the setting concave portion 32, and the concave portion 52 is It supports so that attitude | position change is possible between the open attitude | positions which moved to the outer peripheral side opening from the recessed part 32 for a setting. Further, in the open posture, the opening one side portion of the recess 52 in the lid portion 50 is positioned at the outer peripheral side opening of the setting recess 32. As a result, when the wire bundle 10 is pushed into the setting recess 32, the lid portion 50 can be changed from the open posture to the closed posture, and when the wire bundle 10 is removed from the setting recess 32, the lid portion 50 is removed. The posture can be changed from the closed posture to the open posture.

  In the present embodiment, the set recess 22 and the lid 50 formed in the jig body 30 constitute a set portion 22 that can be detachably and rotatably set at the intermediate portion in the extending direction of the wire bundle 10. ing.

  Here, a pair of lid portions 50 are provided on both sides in the thickness direction of the jig main body 30 so that the tape winding jig 20 can rotate around the wire bundle 10 in a posture that is not inclined as much as possible. . But the number of the cover parts 50 may be one.

  The jig body part 30 is provided with a tape winding body support part 44. Here, the tape 18 has a pressure-sensitive adhesive layer formed on one main surface of a belt-shaped substrate formed of resin or the like, and the tape wound body 16 wound around the single cylindrical core 17 a plurality of times. Provided in the form of The tape winding body support portion 44 is provided so as to be rotatable around the wire bundle 10 together with the set portion 22 around the set portion 22, and in a state in which the tape 18 can be drawn around the set portion 22. It is comprised so that it may support.

  More specifically, the jig main body 30 is configured by a combination of a main body side accommodating portion 40 and a main body side lid portion 48.

  The outer shape of the entire jig body 30 will be described. The jig body 30 is formed in a short elliptical columnar outer shape. That is, the jig body 30 is formed in a shape surrounded by a curved surface that draws an ellipse. The setting recess 32 is formed on one side of the outer periphery of the jig main body 30 in the minor axis X direction of the elliptical shape.

  Further, a recess 36 is formed in a portion other than the portion where the setting recess 32 is formed on the outer periphery of the jig body 30. Here, the recesses 36 are formed at two locations on the outer periphery of the jig body 30 that are approximately the same distance away from the setting recess 32. The recess 36 is formed in a triangular groove shape extending along the thickness direction of the jig body 30. The recess 36 can be used as a clue when the jig body 30 is gripped by a human finger or a robot hand, and can be handled so as not to slide as much as possible.

  Each structure of the main body side accommodating part 40 and the main body side cover part 48 is demonstrated.

  The main body side accommodating portion 40 has a configuration in which a surrounding wall portion 42 is formed around one main surface of an elliptical plate portion 41 (see FIG. 2). The surrounding wall portion 42 is formed not only in the edge portion forming the outer periphery of the ellipse in the plate portion 41 but also in the edge portion where the setting recess 32 is formed and the edge portion where the recess 36 is formed. However, a tape drawing opening 42h communicating with the inside and outside of the surrounding wall portion 42 is formed in a portion adjacent to the outer peripheral side opening of the setting recess 32 in the edge portion where the setting recess 32 is formed. Therefore, the surrounding wall portion 42 is formed on the entire peripheral edge portion of the plate portion 41 except for the tape drawing opening 42h formed at a part of the edge portion where the setting concave portion 32 is formed.

  A tape wound body support portion 44 is provided in the main body side accommodating portion 40. Here, a tape wound body support portion 44 is provided on the inner surface of the plate portion 41 and on the opposite side of the setting recess 32 across the center of the plate portion 41, that is, the other side portion in the minor axis X direction. ing. The tape winding body support portion 44 is formed in a round bar shape or a cylindrical shape that can be inserted into the winding core 17, and protrudes from the inner surface of the plate portion 41. By inserting the tape winding body support portion 44 into the core 17 of the tape winding body 16, the tape winding body 16 is supported by the tape winding body support portion 44 in a state where the tape 18 can be pulled out. The The tape wound body support portion 44 itself may be configured to be rotatably supported with respect to the main body side housing portion 40 by a bearing structure or the like, or the tape wound body support portion 44 itself may not be rotatable. The structure which protrudes in the side accommodating part 40 and the winding core 17 rotates with respect to the tape winding body 16 may be sufficient.

  Further, a guide roller 45 is provided at a position shifted from between the tape wound body support 44 and the set recess 32 in the main body side housing 40. The guide roller 45 is formed in a short columnar shape, and is supported so as to be rotatable with respect to the main body side accommodating portion 40 via a shaft portion 45a.

  The tape winding body 16 is rotatably supported by the tape winding body support portion 44, and the tape 18 drawn from the tape winding body 16 is directed to the tape drawing opening 42h via the guide roller 45. Furthermore, it passes through the set recess 32 and is disposed toward one outer side portion of the outer peripheral side opening of the set recess 32. At this time, the adhesive layer of the tape 18 is disposed in the setting recess 32 so as to face the outer peripheral side opening of the setting recess 32. For this reason, when the wire bundle 10 is pushed into the setting recess 32, the adhesive layer of the tape 18 is attached to the outer periphery of the wire bundle 10. In the above state, the surface of the tape 18 opposite to the adhesive layer is guided by the guide roller 45 while being in contact with the guide roller 45.

  The main body side lid portion 48 is formed in the same elliptical plate shape as the plate portion 41 and is attached to the main body side accommodation portion 40 so as to close the opening of the main body side accommodation portion 40 opposite to the plate portion 41. . The attachment state of both is maintained by a detachable structure such as a screwing or locking structure.

<About the manufacturing method of a tape winding elongate member>
The manufacturing method of the tape winding elongate member using the said tape winding jig | tool 20 is demonstrated. Here, an example in which the tape-wrapped long member is the wire bundle 10 around which the tape 18 is wound, that is, the tape-wrapped wire bundle 110A will be described.

  First, as shown in FIG. 5, the electric wire bundle 10 in which a plurality of electric wires 10a are bundled is supported (step (a)). At this time, two distant portions of the wire bundle 10 are supported by the two wire bundle support members 115 so that the intermediate portion in the extending direction of the wire bundle 10 is supported away from the surroundings. The supporting portion of the wire bundle 10 may be an intermediate portion in the extending direction of the wire bundle 10, or an end connector or the like. Further, the wire bundle 10 may be in a direction (including the horizontal direction) intersecting the vertical direction that is the direction of gravity, or may be in the vertical direction.

  And the set part 22 is set in the extending direction intermediate part of the electric wire bundle 10 (refer process (b), FIG.3 and FIG.4). Specifically, with the lid 50 in the open position and the tape 18 being pulled out from the tape drawing opening 42h and disposed in the setting recess 32, the intermediate portion in the extending direction of the wire bundle 10 is used for setting. The tape winding jig 20 is pressed against the intermediate portion in the extending direction of the wire bundle 10 so as to be pushed into the recess 32. Then, the lid 50 is pushed by the wire bundle 10 to change the posture of the lid 50 to the closed posture, and the intermediate portion in the extending direction of the wire bundle 10 is accommodated between the setting recess 32 and the lid-side recess 52. . At the same time, the end portion of the tape 18 drawn from the tape winding body 16 supported by the tape winding body support portion 44 is attached to the wire bundle 10 (step (c)). Here, step (b) and step (c) are performed at the same time, but it is not always necessary. For example, the end portion of the tape 18 may be attached to the intermediate portion in the extending direction of the electric wire bundle 10 before or after the setting portion 22 is set in the intermediate portion in the extending direction of the electric wire bundle 10.

  Then, as shown in FIGS. 6 to 8, the tape winding jig 20 is rotated around the wire bundle 10 in a state where the set portion 22 is set in the intermediate portion in the extending direction of the wire bundle 10 (step (d )). Then, the tape winding jig 20 rotates together with the tape winding body 16 and the tape 18 drawn from the tape winding body 16 with the end portion of the tape 18 being attached to the outer periphery of the wire bundle 10. 18 is sequentially wound around the outer circumference of the wire bundle 10 while being drawn out from the tape winding body 16. It should be noted that a tension according to the force required to pull out the tape 18 from the tape winding 16 acts on the tape 18 drawn out from the tape winding 16 against the adhesive force of the tape 18. For this reason, the tape 18 is wound so as to be in close contact with the wire bundle 10 in a state where a certain amount of tension is applied. When the tape winding jig 20 is rotated around the wire bundle 10 a desired number of times (one or more times), the tape 18 is wound around the wire bundle 10 a desired number of times.

  Thereafter, when the tape winding jig 20 is moved away from the wire bundle 10 so that the intermediate portion in the extending direction of the wire bundle 10 moves toward the opening on the outer peripheral side of the setting recess 32, the lid portion 50 is in the open posture. Then, the tape winding jig 20 is removed from the wire bundle 10. Then, when the portion of the tape 18 wound around the wire bundle 10 and the portion remaining on the tape winding jig 20 side is cut with a finger, a cutter or the like, as shown in FIG. 9, the tape-wrapped wire bundle 110A is manufactured.

  As shown in FIG. 10, when the step (d) is performed, the tape winding jig 20 is moved along the extending direction of the electric wire bundle 10 while the tape winding jig 20 is moved to the electric wire bundle 10. When rotated around, a tape-wrapped electric wire bundle 110 </ b> B in which the tape 18 is spirally wound around the electric wire bundle 10 as shown in FIG. 11 can be manufactured. By relatively adjusting the speed at which the tape winding jig 20 moves along the extending direction of the electric wire bundle 10 and the speed at which the tape winding jig 20 rotates around the electric wire bundle 10, the tape 18 is connected to the electric wire. The bundle 10 can be wound roughly (in a mode in which the tape 18 is wound with a gap between the spirals) or densely wound (in a mode in which the tape 18 is partially overlapped between the spirals). You can also

  According to the method of manufacturing the tape winding jig 20 and the tape winding electric wire bundle 110A configured as described above, the set portion 22 is rotatably set at the intermediate portion in the extending direction of the electric wire bundle 10 to support the tape winding body. When the end of the tape 18 drawn from the tape winding body 16 supported by the portion 44 is attached to the electric wire bundle 10 and the tape winding jig 20 is rotated around the electric wire bundle 10 in this state, the tape winding body The tape 18 drawn out from 16 is wound around the wire bundle 10. At this time, since the tape winding jig 20 is rotatably supported with respect to the electric wire bundle 10 by its own set portion 22, the tape winding jig 20 is separately rotatably supported around the tape winding jig 20. There is no need to provide a roller or the like. For this reason, the space which can rotate the tape winding jig | tool 20 should just exist around the electric wire bundle 10. FIG. Therefore, even when it is difficult to secure a wide working space around the wire bundle 10, the tape 18 can be easily wound around the wire bundle 10.

  In particular, when a wire harness in which a plurality of electric wires are branched and bundled as a long member is assumed, the wire harness has a trunk portion and a plurality of branch portions. When the tape 18 is wound around the portion, another portion of the electric wire bundle 10 is present nearby (see the two-dot chain line in FIG. 6). Thus, even when another wire bundle 10 portion is close to the wire bundle 10 portion to be wound with the tape 18, a space saving that allows the tape winding jig 20 to rotate is saved. If it can be secured, the tape 18 can be wound. Therefore, the winding operation of the tape 18 can be easily performed at a place where a plurality of branch line portions are densely arranged in the wire harness. Moreover, since the tape winding jig 20 is light and compact, it can be easily moved to perform tape winding operations in a wider variety of places.

  Further, since the tape winding jig 20 is rotatably supported by the self set portion 22 with respect to the electric wire bundle 10, the winding operation of the tape 18 rotates the tape winding jig 20 around the electric wire bundle 10. This can be done by applying a force in the direction to be applied. For this reason, as shown in FIG. 12, the winding operation of the tape 18 can be easily performed by, for example, the robot 120 (here, the fingers of a humanoid robot) which is inferior in dexterity compared to the manual operation. This contributes to the automation of wire harness manufacturing work.

  Further, the tape winding jig 20 includes a jig main body 30 having a setting concave portion 32 formed on the outer periphery, an opening posture in which the jig main body 30 opens the outer peripheral side opening of the setting concave portion 32, and a setting concave portion. A lid 50 supported so as to be capable of changing its posture between a closed posture for closing the outer peripheral side opening of the 32, the set portion 22 includes the setting recess 32 and the lid portion 50, and the tape wound body support portion 44. Is provided in the jig main body 30, and the intermediate portion in the extending direction of the wire bundle 10 is disposed in the setting recess 32 in a state where the lid portion 50 is in the open posture. If the posture is changed to the closed posture, the intermediate portion in the extending direction of the wire bundle 10 can be easily and reliably set on the set portion 22. After that, if the lid portion 50 is changed to the open posture, the set portion 22 can be easily removed from the intermediate portion in the extending direction of the wire bundle 10.

  The jig main body 30 is formed in a short elliptical columnar outer shape, and is surrounded by a curved surface that protrudes outward. For this reason, when rotating the tape winding jig 20 around the electric wire bundle 10, the jig main body 30 is not easily caught by surrounding members (for example, other electric wires).

  Similarly, the lid part 50 is also formed in a short elliptical columnar outer shape and is surrounded by a curved surface that protrudes outward. For this reason, when the tape winding jig 20 is rotated around the wire bundle 10, the lid 50 is not easily caught by surrounding members (for example, other electric wires).

  In addition, even if the jig main body part or the lid part is not formed in a short elliptical columnar outer shape and is formed in a short cylindrical outer shape, it is difficult to be caught by surrounding members. That is, when the jig main body part or the lid part is formed in a shape surrounded by a curved surface that protrudes outward, it is difficult to catch them on the surrounding members.

  Moreover, the jig body 30 is formed into a short elliptical columnar outer shape, that is, a shape surrounded by a curved surface that draws an ellipse, and a setting recess 32 is formed on one side of the short axis X direction, Since the tape winding body support portion 44 is provided on the other side of the short axis X direction, the space required for rotating the tape winding jig 20 around the wire bundle 10 can be further reduced. Since the jig body 30 rotates around the wire bundle 10 disposed in the set recess 32, the size of the set recess 32 and the portion opposite to the set recess 32 can be reduced. This is because the locus when the jig main body 30 rotates around the wire bundle 10 becomes small.

  Moreover, since the recessed part 36 is formed in the outer periphery of the jig | tool main body part 30, the said jig | tool main body part 30 can be hold | maintained firmly, suppressing a slip etc. more reliably by using the said recessed part 36 as a clue. In addition, the jig body 30 is less likely to be caught by surrounding members when the tape winding jig 20 is rotated around the wire bundle 10 as compared with the case where a convex portion is formed on the outer periphery of the jig body.

<Modification>
The configuration of the lid portion 50 that allows the opening of the setting recess 32 to be opened and closed is not limited to the above example. For example, a lid that can be opened and closed by sliding may be provided with respect to the opening of the set recess. Further, a lid that can be elastically deformed and opened / closed may be provided with respect to the opening of the set recess.

  It is not essential that the lid is provided. Further, it is not essential that the jig main body has the shape described in the above embodiment.

  For example, in the tape winding jig 220 according to the modification shown in FIG. 13, the set part 222 is formed at one end of the long jig main body 240, and the tape winding body support 244 is provided at the other end. It has been.

  The jig body 240 is formed in an elongated plate shape.

  The set part 222 is formed in a C shape. One end of the set portion 222 is connected to one end of the jig main body 240 in a posture in which the opening of the set portion 222 faces the jig main body 240. A space that can accommodate the wire bundle 10 is formed in the set portion 222. The set part 222 is formed to be elastically deformable, and the opening width of the set part 222 is set larger than the outer diameter dimension of the wire bundle 10. Then, the wire bundle 10 can be set in the set portion 222 by elastically expanding the opening of the set portion 222. Thereby, the set part 222 can be set to be attachable and detachable and rotatable at an intermediate part in the extending direction of the wire bundle 10.

  In addition, the tape winding body support portion 244 is formed in a round bar shape or a cylindrical shape, like the tape winding body support portion 44. One end of the tape winding body support 244 is placed on the other side of the jig main body 240 in a posture in which the axial direction of the tape winding body support 244 coincides with the extending direction of the wire bundle 10 set on the set unit 222. It is supported at the end. In addition, it is preferable that the tape winding body support part 244 is formed with a retaining protrusion for preventing the winding core 17 from coming off.

  And in the state which set part 222 was set in the extension direction middle part of electric wire bundle 10, tape 18 was pulled out from tape winding body 16 supported by tape winding body support part 244, and the end of the tape 18 was moved. It is attached to the outer periphery of the wire bundle 10. Thereafter, if the tape winding jig 220 is rotated around the electric wire bundle 10, the tape 18 can be wound around the electric wire bundle 10 as in the above embodiment.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
