{Embodiment}
Hereinafter, a tape winding apparatus according to an embodiment and a wire harness manufacturing apparatus including the same will be described. FIG. 1 is a schematic perspective view showing a wire harness manufacturing apparatus 20 according to the embodiment. FIG. 2 is a schematic front view showing the tape winding device 30 according to the embodiment. FIG. 3 is a schematic front view showing the tape winding device 30 that is winding the adhesive tape 18. In FIG. 1, a tape winding mechanism 31 to be described later is partially omitted.

  The wire harness manufacturing apparatus 20 includes a tape winding apparatus 30 and a drawing board 50. The wire harness manufacturing apparatus 20 applies the adhesive tape 18 to the portion (hereinafter referred to as the branching portion 13) that intersects each other of the electric wires 12 arranged on the drawing board 50 by the tape winding device 30. It is provided so that it can be wound.

  The tape winding device 30 includes a tape winding mechanism 31, a tape winding mechanism rotation mechanism 42, and a tape winding mechanism moving mechanism 46. The tape winding device 30 winds the adhesive tape 18 around the linear body by rotating the tape winding body 18B around which the adhesive tape 18 is wound around the linear body. Below, the electric wire 12 is assumed as a linear body.

  The tape winding mechanism 31 includes a rotator 32, a wound body support portion 33, a rotation support portion 34, and a rotator rotation drive portion 36.

  The rotating body 32 is configured such that a U-shaped recess 32h is formed from a part around the outer periphery of the disk-shaped member toward the center. An arcuate guide 32a is provided on one side of the rotating body 32 (downstream in the pull-out direction).

  A pair of arcuate guides 32a are provided, and each plate-like member is formed in a shape that is bent into a substantially quarter arcuate shape. The pair of arcuate guides 32a is attached to the rotating body 32 at the periphery of the bottom of the recessed portion 32h of the rotating body 32 with the concave surface facing the recessed portion 32h. At this time, the one end of one arcuate guide 32a and the one end of the other arcuate guide 32a are arranged to face each other with a gap therebetween. And the front-end | tip side part of the adhesive tape 18 extended from the tape winding body 18B is passed between a pair of arcuate guides 32a, and the front-end | tip of the adhesive tape 18 before affixing on a linear body is the electric wire 12. It is hold | maintained so that it may be located in the position which can be stuck to.

  The wound body support portion 33 is provided on the one surface side of the rotating body 32 at a portion on the outer peripheral side with respect to the rotation center of the rotating body 32. Here, the wound body support portion 33 is provided on the rotating body 32 via a path changing portion 37 described later. But the wound body support part 33 may be provided in the rotary body 32 directly. The wound body support portion 33 rotatably supports the tape wound body 18B in which the adhesive tape 18 is wound and accommodated.

  The rotation support portion 34 is formed in a flat plate shape and has a configuration in which a recess 34 h is formed from one outer edge portion toward the center. A bearing portion 34a that rotatably supports the rotating body 32 in a state where the bottom portion of the recess 32h and the bottom portion of the recess 34h communicate with each other is provided, and a rotation support disk 34c and the like are provided at positions around the rotating body 32. Is disposed, the rotating body 32 is rotatably supported by the rotation support portion 34. The rotating body 32 is rotated with respect to the rotation support portion 34, and the position of the recess 32 h of the rotation body 32 is matched with the position of the recess 34 h of the rotation support portion 34, so It can be done. Further, by rotating the rotating body 32 in this state, the tape winding body 18 </ b> B can be rotated around the electric wire 12 disposed in the center of the rotating body 32. The recess 34h is preferably formed along the moving direction of the tape winding mechanism 31 by the tape winding mechanism moving mechanism 46.

  The rotating body rotation driving unit 36 is configured to be able to rotate the rotating body 32. Here, the rotating body rotation drive unit 36 is configured by a motor or the like. Here, the two rotation support disks 34 c provided around the rotating body 32 are constituted by gears, and the gears mesh with the gears formed around the rotating body 32. A drive gear 36a attached to the drive shaft of the rotating body rotation drive unit 36 is engaged with the two rotation support disks 34c. Then, the rotational drive force of the rotary body rotation drive unit 36 is transmitted from the drive gear 36a to the rotary body 32 via the two rotary support disks 34c, whereby the rotary body 32 is rotationally driven. At this time, regardless of the position of the recess 32 h of the rotating body 32, at least one of the two rotating support disks 34 c meshes with a gear formed around the rotating body 32. For this reason, the rotating body 32 can be continuously rotated by 360 degrees or more. The rotator rotation drive unit 36 is an example of a first rotator rotation drive unit.

  The adhesive tape 18 can be wound around the electric wire 12 by rotating the tape winding body 18 </ b> B around the electric wire 12 by the tape winding mechanism 31.

  The tape winding mechanism rotating mechanism 42 rotates the tape winding mechanism 31. The tape winding mechanism rotation mechanism 42 includes a base 43 and a base rotation drive unit.

  The base 43 is formed in a flat plate shape (here, a disc shape). A rotation support portion 34 is provided on one main surface of the base 43. A tape winding mechanism moving mechanism 46 is provided on the other main surface of the base 43. The base 43 is provided so as to be rotatable around an axis that intersects (in this case, is orthogonal) with the main surface.

  The base rotation drive unit rotates the rotation body 32 around a rotation axis that intersects the central axis of the rotation body 32 when the rotation body 32 is rotated by the rotation body rotation drive unit 36. The base rotation driving unit is an example of a second rotating body rotation driving unit. Here, the base rotation driving unit is configured by a motor or the like. The base rotation drive unit is provided so as to be able to be driven to rotate around an axis that intersects (in this case, orthogonally) the base 43 with the base surface. When the base rotation drive unit rotates the base 43, the rotation support unit 34 provided on the base 43 rotates around an axis orthogonal to the main surface of the base 43. Thereby, the rotating body 32 supported by the rotation support portion 34 rotates around an axis orthogonal to the main surface of the base 43, and the direction related to the winding direction of the tape can be changed.

  The tape winding mechanism moving mechanism 46 is provided so that the tape winding mechanism 31 can reciprocate. The tape winding mechanism moving mechanism 46 reciprocates the tape winding mechanism 31 and the tape winding mechanism rotating mechanism 42 along a direction parallel to the rotation axis of the base rotation driving unit. The tape winding mechanism moving mechanism 46 is constituted by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor. The linear actuator is disposed along a direction parallel to the rotation axis of the base rotation drive unit, that is, a direction orthogonal to the main surface of the base 43. Then, by connecting one end of the linear actuator to the base 43, the base 43 reciprocates along the direction orthogonal to the main surface of the base 43 by the linear actuator. As a result, the tape winding mechanism 31 provided on the base 43 is supported so as to be movable toward or away from the electric wire 12 along a direction parallel to the rotation axis of the base rotation drive unit. The tape winding mechanism moving mechanism 46 is an example of a reciprocating mechanism.

  The drawing board 50 is formed in a flat plate shape and includes a drawing board main body 52 in which a plurality of electric wires 12 are disposed. The plurality of electric wires 12 are arranged on one main surface of the board main body 52 according to the arrangement form in the vehicle. Here, as shown in FIG. 1, the plurality of electric wires 12 are arranged such that portions (branching portions 13) intersecting each other are generated. An insertion hole 53 is formed in the figure main body 52 at a position corresponding to the branch portion 13.

  The insertion hole 53 is formed in a shape capable of inserting the rotating body 32 of the tape winding device 30. Then, the rotating body 32 is inserted into the insertion hole 53 and the adhesive tape 18 is wound around the branching portion 13 by rotating the rotating body 32 in a state where the branching portion 13 is housed in the recess 32h. Therefore, the insertion hole 53 is preferably formed to be larger than the rotation radius of the rotating body 32 related to the tape winding and the tape winding body 18B rotating together with the rotating body 32. In the example shown in FIG. 1, the rotating body 32 is inserted into the insertion hole 53 from the other main surface side of the drawing board main body 52, but this is not essential. The rotating body 32 may be inserted into the insertion hole 53 from the one main surface side of the figure board main body 52.

  The figure body 52 is provided with a connector holding jig 54 for holding the connector 14 provided at the end of the electric wire 12. The connector holding jig 54 is provided at a position corresponding to the wiring form of the vehicle. In FIG. 1, one electric wire 12 is drawn to extend from the connector 14, but actually, there may be a plurality of electric wires 12.

  Further, an electric wire holding jig 55 for holding the electric wires 12 is erected on the drawing board main body 52. The electric wire holding jig 55 is erected on the edge of the insertion hole 53. The electric wire holding jig 55 includes, for example, an electric wire 12 holding portion formed in a U shape. The arrangement state of the electric wires 12 is maintained by passing the electric wires 12 arranged according to the wiring form of the vehicle through the electric wire 12 holding portion.

  In the example shown in FIG. 2, the tape winding mechanism 31 includes a path changing unit 37. However, the tape winding mechanism may not include the path changing unit 37.

  The path changing unit 37 is provided on one surface side of the rotating body 32. By providing the path changing unit 37, the length dimension of the portion 18a between the tape winding body 18B and the linear body in the adhesive tape 18 can be changed.

  Specifically, the path changing unit 37 includes a linear guide 39 and an elastic unit 40.

  The linear guide 39 includes a rail 39a and a slider 39b. Here, the path changing portion support member 41 is attached to the rotating body 32. One end of the rail 39 a of the linear guide 39 is attached to the path changing portion support member 41. The other end of the rail 39 a extends in a direction away from the central axis of the rotating body 32. A slider 39b is slidably provided along the rail 39a. A winding body support portion 33 is provided on the slider 39b. It should be noted that slider stops may be provided at both ends of the rail 39a.

  The elastic portion 40 is a portion that is formed of, for example, a tension coil spring or an air spring, and generates a biasing force in the direction of increasing the extra length of the span portion 18a. Here, the elastic portion 40 is provided so as to connect one end of the rail 39a and the slider 39b. The elastic portion 40 biases the slider 39b toward the other end side of the rail 39a.

  The wound body support portion 33 is attached to the slider 39b. The adhesive tape 18 extends straight from the tape wound body 18 </ b> B supported by the wound body support portion 33 toward the electric wire 12. Therefore, the tape winding body 18B is located outside the central axis of the rotating body 32 and is supported so as to be able to approach and separate from the central axis. Thereby, in the tape winding mechanism 31, as shown in FIG. 3, the length of the span part 18a is changed because the elastic part 40 is elastically deformed.

  The path changing unit 37 is configured to change the state of the extending portion 18a from the long state to the short state when the rotating body 32 is rotated and the adhesive tape 18 is wound around the electric wire 12. In the state where the span portion 18a is long, the extra length is larger than that in the short state. And when the tape winding pressure is likely to increase during the tape winding, the extra length portion is wound around the linear body by changing the state of the portion 18a from the long state to the short state. Thus, the winding pressure is suppressed from increasing. Thereby, in winding the adhesive tape 18 so as to cross the branch portion 13 of the electric wire 12, it is possible to suppress the electric wire 12 from being pulled strongly by the adhesive tape 18. As a result, the situation where the end of the electric wire 12 comes off from the connector 14 is suppressed.

  In the tape winding device 30, the operation of first sticking the tip of the adhesive tape 18 that extends from the tape winding body 18 </ b> B to the electric wire 12, and the adhesive tape 18 after the end of the tape winding. The operation | movement etc. which cut | disconnect may be automated. The former operation is automated, for example, by providing a tape application portion in which the tip of the adhesive tape 18 that is a free end is arranged so as to be movable toward the electric wire 12. The latter operation is automated by, for example, providing a tape cut portion configured such that a blade capable of cutting the adhesive tape 18 after the end of winding of the tape is movable toward the span portion 18a.

  The operation control of each part of the tape winding device 30 is performed by the control unit 80. The control unit 80 includes a microprocessor, a main storage unit coupled to the microprocessor, and an auxiliary storage unit. The main storage unit is configured by a RAM (Random Access Memory) or the like, and the auxiliary storage unit is configured by a non-temporary storage device such as a flash memory, an EPROM (Erasable Programmable ROM), or a hard disk device. The auxiliary storage unit stores a program describing instructions for the microprocessor. The microprocessor reads the program and executes each processing step described later. Note that some or all of the various processes executed by the control unit 80 may be realized by hardware. Here, the drive timing (conditions), operation details (movement position, movement direction, rotation amount), etc. of each of the above-mentioned drive units are described in the program. Perform the operations described.

<Manufacturing method>
Next, the operation | movement which winds the adhesive tape 18 to the electric wire 12 using the tape winding apparatus 30 is demonstrated with the manufacturing method of the wire harness 10 by the wire harness manufacturing apparatus 20. FIG. Moreover, the operation | movement which winds the adhesive tape 18 around the electric wire 12 using the tape winding apparatus 30 is demonstrated, referring FIG. 4 thru | or FIG. 6 in addition to FIG. 1 thru | or FIG. 4 to 6 are explanatory views showing a state where the adhesive tape 18 is wound using the tape winding device 30. FIG. 4 to 6, the tape winding mechanism 31 other than the rotating body 32 is omitted.

  First, as shown in FIG. 1, the electric wires 12 are arranged on the drawing board main body 52. Here, the positions of the connector holding jig 54 and the electric wire holding jig 55 are determined so that the branch portion 13 is positioned at the portion where the insertion hole 53 is formed, and the electric wire is held while the connector holding jig 54 holds the connector 14. The electric wire 12 is held by the holding jig. At this time, the rotating body 32 is located at a position away from the position corresponding to the branch portion 13 in the insertion hole 53 in the direction orthogonal to the main surface of the drawing board main body 52.

  Next, the rotating body 32 is inserted through the insertion hole 53. As shown in FIG. 4, the rotating body 32 extends obliquely with respect to the electric wires 12 crossing the cross, that is, the direction in which the main surface of the rotating body 32 extends from the branch portion 13 when viewed from the insertion direction. The rotating body 32 is inserted through the insertion hole 53 while intersecting the extending direction of the electric wire 12. Here, the tape winding mechanism moving mechanism 46 is driven to bring the tape winding mechanism 31 closer to the drawing board main body 52 from the outside of the other main surface of the drawing board main body 52, and the rotating body 32 is inserted into the insertion hole. 53 is inserted.

  Even after the rotator 32 is inserted into the insertion hole 53, if the rotator 32 is moved as it is by the tape winding mechanism moving mechanism 46, the branch portion 13 will eventually fit in the recess 32h. In this state, the rotating body 32 is moved until the branch portion 13 is positioned at the center of the rotating body 32. At this time, the rotating body 32 and the branch portion 13 are preferably in a positional relationship such that the adhesive tape 18 can be attached to the center of the branch portion 13. For example, it is conceivable that the position of the branch portion 13 slightly shifted from the center to the side is accommodated in the rotating body 32.

  When the branch portion 13 is positioned at the center of the rotating body 32, the drive of the tape winding mechanism moving mechanism 46 is stopped. Thereafter, the tip of the adhesive tape 18 extending from the tape winding body 18 </ b> B is attached to the branch portion 13. Then, the rotating body rotation drive unit 36 is driven to rotate the rotating body 32 around the central axis of the rotating body 32. Thereby, the rotary body 32 rotates around the branch portion 13, the adhesive tape 18 is wound around the first portion around the branch portion 13, and the first winding portion 19 a is formed. When the first winding portion 19a is formed, the rotating body rotation driving unit 36 stops.

  Next, the rotating body 32 is separated from the branch portion 13. Here, the tape winding mechanism moving mechanism 46 is driven, the tape winding mechanism 31 is separated from the drawing board main body 52, and the rotating body 32 is removed from the insertion hole 53.

  When the rotator 32 is separated from the branch portion 13, next, the rotator 32 is rotated around the rotation axis intersecting the center axis to change the direction of the center axis of the rotator 32. Here, the base rotation driving unit is driven to rotate the base 43 by 90 degrees around an axis orthogonal to the main surface of the base 43. As a result, the tape winding mechanism 31 provided on the base 43 also rotates 90 degrees around an axis orthogonal to the main surface of the base 43, and the direction of the central axis of the rotating body 32 rotates 90 degrees as shown in FIG. .

  When the direction of the central axis of the rotating body 32 changes, the rotating body 32 is moved closer to the branch portion 13. Here, in the same manner as when the adhesive tape 18 is first wound around the branch portion 13, the tape winding mechanism moving mechanism 46 is driven to move the tape winding mechanism 31 from the outside of the other main surface of the figure main body 52. The rotating body 32 is inserted into the insertion hole 53 by approaching the figure main body 52.

  When the branch portion 13 is positioned at the center of the rotating body 32, the drive of the tape winding mechanism moving mechanism 46 is stopped. Then, the rotating body rotation drive unit 36 is driven to rotate the rotating body 32 around the central axis of the rotating body 32. As a result, the rotating body 32 rotates around the branch portion 13, and the adhesive tape 18 is wound around the second axis that intersects (is orthogonal to) the first axis with respect to the branch portion 13. A winding part 19b is formed. If the 2nd winding part 19b is formed, the rotary body rotation drive part 36 will stop.

  Thereafter, the adhesive tape 18 is cut and the tape winding mechanism 31 is separated from the branch portion 13 to complete the tape winding operation on the branch portion 13, and as shown in FIG. A wire harness 10 in which 18 is wound in a cross is manufactured. Note that winding around the cross here means that the adhesive tape 18 is wound in two directions intersecting each other, and the two directions do not need to be orthogonal.

  After the first tape winding operation for winding the adhesive tape 18 around the first axis around the branch portion 13, the second tape around which the adhesive tape 18 is wound around the second axis around the branch portion 13. When moving to the winding operation, the adhesive tape 18 may be cut or may not be cut. When the adhesive tape 18 is cut when moving from the first tape winding operation to the second tape winding operation, the adhesive tape 18 is twisted when the direction of the central axis of the rotating body 32 is changed. It is suppressed that 18 adhesion surfaces adhere. When the adhesive tape 18 is not cut when moving from the first tape winding operation to the second tape winding operation, the tape cutting operation and the tape applying operation can be omitted once.

  According to the tape winding device 30 and the wire harness manufacturing apparatus 20 including the tape winding device 30, the rotating body 32 is rotated by rotating the rotating body 32 around the rotation axis intersecting the central axis of the rotating body 32 by the base rotation driving unit. Can change the central axis of the rotating body 32 when rotating around the electric wire 12. Thus, after the adhesive tape 18 is once wound around the branch portion 13, the direction of the rotating body 32 is changed, and the adhesive tape 18 is wound around the branch portion 13 again, thereby using the tape winding device 30 to branch the branch portion 13. The adhesive tape 18 can be wound around the cross.

  Further, since the tape winding mechanism moving mechanism 46 for reciprocating the rotating body 32 along the direction parallel to the rotation axis of the base rotation driving unit is further provided, the moving toward and away from the electric wire 12 is facilitated. Can be done.

  Further, the tape can be easily wound around the branch portion 13 of the electric wire 12 disposed in the figure main body 52 by the rotating body 32 of the tape winding device 30 inserted through the insertion hole 53 of the figure board 50. Become.

  Further, by rotating the rotating body 32 around the rotation axis intersecting the central axis and changing the direction of the central axis of the rotating body 32, the tape is wound around the first axis and the second axis around the branch portion 13. wear. As a result, the tape can be wound around the branch portion 13 in a cross shape.

{Modifications}
In the embodiment, it has been described that the insertion hole 53 is formed in the drawing board 50, but this is not essential. When the insertion hole 53 is not formed in the drawing board 50, it is conceivable that the tape winding device 30 is moved closer to and away from one main surface side of the drawing board 50.

  In the embodiment, the electric wire holding jig 55 is described as being provided at the edge of the insertion hole 53, but this is not essential. The electric wire holding jig 55 may be provided at a position closer to the branch portion 13. In this case, it is conceivable that the electric wire holding jig 55 is provided so as to be movable or changeable in posture so as not to interfere with the tape winding operation. The moving direction may be a direction intersecting the main surface of the drawing board 50 or a direction parallel to the direction in which the main surface of the drawing board 50 spreads. Further, as the posture change, for example, it is conceivable that the posture can be changed between a posture in which the jig is erected with respect to the drawing board 50 and a posture in which the jig is tilted with respect to the drawing board 50. Further, when the electric wire holding jig 55 is provided at a position closer to the branch portion 13, as shown in FIG. 7, the adhesive tape 18 is provided on the opposite side of the branch portion 13 with respect to the electric wire holding jig 55. It is also possible to wrap around. Thereby, even if the electric wire holding jig 55 is moved away from the branch portion 13 before the adhesive tape 18 is wound around the branch portion 13 in a cross shape, the branch shape of the branch portion 13 is maintained to some extent. As a result, it becomes easy to wind the adhesive tape 18 around the branch portion 13 in a cross using the tape winding device 30.

  Moreover, in embodiment, although demonstrated as what winds the adhesive tape 18 to what is called four branches where four branch lines extend from one branch point, this is not essential. The adhesive tape 18 may be wound around the branch portion 13 having three branches or five or more branches. When the adhesive tape 18 is wound around the branch portion 13 having five or more branches, the adhesive tape 18 may be further wound around an axis that intersects the first axis and the second axis, respectively.

  In the embodiment, the linear actuator is used as the tape winding mechanism moving mechanism 46. However, this is not essential. For example, an articulated robot arm may be used as the tape winding mechanism moving mechanism.

  In addition, each structure demonstrated by 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.
