  Hereinafter, embodiments will be described with reference to the accompanying drawings. The following embodiment is an example embodying the present invention, and is not an example of limiting the technical scope of the present invention.

  In this embodiment, the tape winding device 290 and the tubular exterior member mounting device 20 will be described. The tape winding device 290 includes a tape winding unit 3X, a relative movement mechanism, and a clamping unit 90, as will be described later. The tape winding device 290 is incorporated in the tubular exterior member mounting device 20.

  First, an electric wire module 10 with a tubular outer member manufactured using the tubular outer member mounting device 20 will be described with reference to FIGS. FIG. 1 is a schematic view of an electric wire module 10 with a tubular outer member. 8 and 14 are explanatory views showing the operation of the tube-shaped exterior member mounting device 20, in which the corrugated tube 16 in the wire module 10 with the tube-shaped exterior member is depicted.

  As shown in FIG. 1, the electric wire module 10 with a tubular outer member has a configuration in which a corrugated tube 16 is attached to the electric wire 12 as a tubular outer member.

  Here, the tube-shaped exterior member-attached electric wire module 10 includes an electric wire module 10 </ b> B including a plurality of electric wires with terminals 11 and a connector 14, and a corrugated tube 16.

  Any one end portion of the plurality of terminal-attached electric wires 11 is inserted and connected to the connector 14 to constitute a single wiring member. The other end portions of the plurality of terminal-attached electric wires 11 may be connected to other connectors or may remain unconnected to other connectors.

  Here, it is assumed that the wire module 10 with the tubular exterior member is a temporary connection (also referred to as a sub-assembly) that constitutes a part of the wire harness for vehicle wiring. That is, when manufacturing a wire harness used as a wiring in a vehicle or the like, the wire harness is manufactured by dividing it into a temporary form that is smaller than the finished product form, and a plurality of the temporary forms are combined to form a finished form of the wire harness. Construction method may be adopted.

  The electric wire module 10 </ b> B before the corrugated tube 16 is attached includes one or a plurality of terminal-attached electric wires 11 and one or a plurality of connectors 14. One or a plurality of terminal-attached electric wires 11 and one or a plurality of connectors 14 are physically connected by inserting or connecting one end of the terminal-attached electric wires 11 to the connector 14. The terminal-attached electric wire 11 and one or a plurality of connectors 14 are handled as a single wiring material. A wire harness is manufactured by combining the electric wire module 10B with another temporary connection, electric wire, or the like.

  Here, the wire bundle portion 11 </ b> B is configured such that a plurality of terminal-attached wires 11 are inserted and connected to either or both of the two connectors 14. And the corrugated tube 16 is armored with respect to the two wire bundle portions 11B inserted and connected to the two connectors 14 of the terminal-attached electric wires 11, thereby constituting the electric wire module 10 with a tube-like outer member.

  The corrugated tube 16 is a cylindrical member made of resin in which thick annular portions 16a and narrow annular portions 16b are alternately connected (see FIG. 8). Such a corrugated tube 16 can be bent and deformed relatively easily. For this reason, the corrugated tube 16 is used as a member that protects the wire bundle portion 11B while keeping the wire bundle portion 11B to be protected easily bent. A slit 17 is formed in the corrugated tube 16 along the extending direction (see FIG. 14). The corrugated tube 16 is opened by the slit 17 and attached to the wire bundle portion 11B. In addition, although demonstrated here in the example which attaches the corrugated tube 16 to the wire bundle part 11B in which the several electric wire 11 with a terminal was bundled, and winds the adhesive tape 18, it attaches a corrugated tube with respect to a single electric wire, and adheres. The same applies to the case of winding a tape.

  As described above, the adhesive tape 18 is wound around the corrugated tube 16. Here, the adhesive tape 18 is wound around both ends of the corrugated tube 16 and the wire bundle portion 11B extending from the end. Thereby, the corrugated tube 16 is positioned at a fixed position with respect to the wire bundle portion 11B. It is not essential that the adhesive tape 18 is wound around the wire bundle portion 11B at both ends of the corrugated tube 16.

  The adhesive tape 18 is also wound around the intermediate part of the corrugated tube 16. Here, the adhesive tape 18 is wound spirally so as to overlap each other in the extending direction of the corrugated tube 16 in each winding turn (this winding method may be called close winding). For example, the pressure-sensitive adhesive tape 18 is wound so as to overlap about half in the width direction of the pressure-sensitive adhesive tape 18 (this winding method is sometimes called half-wrapping). The adhesive tape 18 may be spirally wound with a gap so as not to overlap each other in the extending direction of the corrugated tube 16 in each winding turn (this winding method may be called rough winding). Thus, by winding the adhesive tape 18, the opening of the slit 17 of the corrugated tube 16 is suppressed. In the tube-shaped exterior member mounting apparatus 20 described later, the adhesive tape 18 is wound around at least an intermediate portion of the corrugated tube 16.

  It is not essential that the tubular exterior member is the corrugated tube 16. The tube-shaped exterior member may be an easily bendable tubular member formed of resin or the like.

  Moreover, it is not essential that the tube-shaped exterior member-attached electric wire module is a temporary structure constituting a part of the wire harness. The wiring material which comprises the whole wire harness may be sufficient as a tube-shaped exterior member attachment electric wire module.

As the end attachment member attached to the end of the wire bundle portion 11B, there may be a case where the terminal is connected and attached to the exposed core portion of the end of the wire by crimping or welding in addition to the connector 14. In particular, when the terminal is a terminal (for example, a ground terminal) that is bolted to the other side, the terminal itself is relatively strong, and thus is suitable for pulling an electric wire.

  More specifically, the wire pulling mechanism 82 includes a pull driving unit 84 and a connector set unit 86. The tension drive part 84 is comprised by linear actuators, such as an air cylinder, a hydraulic cylinder, and a linear motor, and is supported on the base board 51 in the position away from the electric wire bundle part 11B to the side. And the movable part 85 supported so that it can move along the extension direction of the electric wire bundle part 11B by the tension drive part 84 is supported so that it may extend toward the electric wire bundle part 11B from the tension drive part 84. The connector set portion 86 is supported on the distal end portion of the movable portion 85.

  The connector set portion 86 is formed with a concave portion 86h into which the connector 14 can be fitted, and the connector 14 is supported in a fixed position with respect to the connector set portion 86 by fitting the connector 14 into the concave portion 86h. The connector set unit may be configured to sandwich and support the connector 14. Further, the electric wire pulling mechanism may be configured to pull the electric wire bundle portion 11B while holding the electric wire bundle portion 11B.

  And in the state where the connector 14 is set in the connector set part 86, the connector set part 86 is moved in the direction away from the tube exterior jig 60 along the extending direction of the wire bundle part 11B by the tension drive part 84, The connector 14 moves in the same direction, so that the wire bundle portion 11B is pulled away from the tube exterior jig 60 along the pulling direction of the wire bundle portion 11B.

  It is not essential that the pulling mechanism 80 includes the electric wire pulling mechanism 82. The structure provided with the tube pulling mechanism which pulls out the corrugated tube 16 may be sufficient as the pulling mechanism, for example. If one end of the corrugated tube 16 and the wire bundle portion 11B are fixed by the winding start portion of the adhesive tape 18, both of them are pulled by pulling one end of the corrugated tube 16 and the wire bundle portion 11B. It is because it can pull.

  In the tube-shaped exterior member mounting device 20, the guide groove portion 26 is provided on the tube exterior jig 60 on the side opposite to the pulling direction of the wire bundle portion 11 </ b> B, that is, on the wire holding member 22 side. The guide groove 26 is configured to be able to guide the wire bundle portion 11B. For example, the wire bundle portion 11B can be guided by passing the wire bundle portion 11B between a pair of guide surfaces 26a arranged to face each other with a gap therebetween. Thereby, the wire bundle part 11B can be kept linear, and the wire bundle part 11B can easily enter and pass through the exterior jig.

<About tape winding unit>
Next, the tape winding unit 30 will be described with reference to FIGS. The tape winding unit 30 includes a tape winding unit 3X and a clamping unit 90. FIG. 4 is a schematic plan view of the tape winding unit 30. FIG. 5 is a partial cross-sectional view of the clamping unit 90 in the tape winding unit 30. FIG. 6 is a front view of the tape winding portion 3X in the tape winding unit 30. FIG. 9 and 16 are explanatory views showing the operation of the tube-shaped exterior member mounting device 20. In FIG. 9, a tape pressing portion 35 in the tape winding unit 30 is depicted. In FIG. 16, the roller 38a in the tape winding unit 30 is depicted. First, the tape winding part 3X will be described.

  Here, as shown in FIG. 4, the tape winding portion 3 </ b> X is provided on the downstream side in the pulling direction of the wire bundle portion 11 </ b> B with respect to the tube exterior jig 60. When the corrugated tube 16 is pulled from the tube exterior jig 60 by the pulling mechanism 80, the adhesive tape 18 can be wound around the corrugated tube 16.

  More specifically, as shown in FIGS. 4 and 6, the tape winding part 3 </ b> X includes a tape winding mechanism 31, a tape holding part 41, a tape applying part 47, and a tape cutting part 49.

  The tape winding mechanism 31 includes a rotating body 32, a wound body support portion 33, a rotation support portion 34, a rotation driving portion 36, and a path changing portion 37. Further, here, the tape winding mechanism 31 includes a tape pressing portion 35.

  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 arc guide 32a and a tape pressing portion 35 are provided on one surface side (downstream side in the tension direction) of the rotating body 32.

  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 tape pressing. It is hold | maintained so that it may be located in the position which can be stuck to a linear body by the part 35.

  The tape pressing portion 35 is provided so as to be rotatable with respect to the arcuate guide 32 a and the rotating body 32. The tape pressing portion 35 rotates by being pressed by a pressing portion 47a of a tape applying portion 47 described later in a state where the tip of the adhesive tape 18 is positioned between the tape pressing portion 35 and the linear body. The tip of 18 is pressed toward the linear body (see FIG. 10). Specifically, the tape pressing part 35 includes a pressed part 35a and a pressing pad 35b.

  The pressed portion 35a is formed in a plate shape, and is attached so that one end side portion extends outward from the other end side of one arcuate guide 32a. The one end side portion is, for example, in a position that can be pressed by the pressing portion 47a of the tape applying portion 47 in a state where the position of the concave portion 32h of the rotating body 32 and the position of a concave portion 34h described later of the rotation support portion 34 coincide. The outer surface (surface facing away from the linear body side) is pressed by the pressing portion 47a. The other end side part of the pressed part 35a is connected between the rotary body 32 and the arcuate guide 32a via a hinge, for example. At this time, it is conceivable that the pressed portion 35a is biased to the side opposite to the linear body side. Thereby, it can suppress that the to-be-pressed part 35a rotates toward a linear body during rotation of the rotary body 32, and obstructs winding of the adhesive tape 18. FIG.

  The pressing pad 35b is formed of a member that is more flexible than the pressed portion 35a, and plays a role as a buffer member that softens the impact when pressing the tape. The pressing pad 35b is attached to the inner surface (the surface facing the linear body) of the one end side portion of the pressed portion 35a.

  The wound body support portion 33 is provided in a portion from the outer peripheral side on one surface side of the rotating body 32. 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 is configured such that a concave portion 34h is formed from one side portion thereof toward the center in the width direction. The recess 34h is provided with a bearing portion 34a that rotatably supports the recess 32h of the rotating body 32, and a rotation support disk 34c or the like is disposed at a position around the rotating body 32 so that the rotation support portion is provided. The rotating body 32 is rotatably supported by 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 arranged. Further, in this state, by rotating the rotating body 32, the tape winding body 18 </ b> B can be rotated around the wire bundle portion 11 </ b> B at the center of the rotating body 32. Yes.

  The rotation drive unit 36 is configured to be able to rotate the rotating body 32. Here, the 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. In addition, a drive gear 36a attached to the drive shaft of the rotation drive unit 36 meshes with the two rotation support disks 34c. The rotational driving force of the rotational 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.

  Then, while pulling the corrugated tube 16 from the tube exterior jig 60 by the pulling mechanism 80, the tape winding body 18 </ b> B is rotated around the corrugated tube 16 by the tape winding portion 3 </ b> X, whereby the adhesive tape 18 is attached to the corrugated tube 16. Can be wound in a spiral.

  Further, by rotating the tape winding body 18B around the wire bundle portion 11B so that the tip portion of the adhesive tape 18 is wound around the wire bundle portion 11B pulled from the tube exterior jig 60, the tip of the adhesive tape 18 is rotated. The portion can be wound around the wire bundle portion 11 </ b> B outside the one end portion of the corrugated tube 16. In this state, the corrugated tube 16 is moved with respect to the extending direction of the electric wire bundle portion 11B, and the adhesive tape 18 facing outward from the electric wire bundle portion 11B enters the slit 17 of the corrugated tube 16, When the tape winding body 18 </ b> B is rotated around one end portion of the corrugated tube 16 in the state, the adhesive tape 18 is also wound around the one end portion of the corrugated tube 16. Thereby, the adhesive tape 18 is wound around the electric wire bundle part 11B and the one end part of the corrugated tube 16, and the one end part of the corrugated tube 16 and the electric wire bundle part 11B can be fixed.

  The path changing unit 37 is provided on one surface side of the rotating body 32. The path changing unit 37 has a first state (hereinafter referred to as a short state) in which the span portion 18a has a predetermined length dimension, and a second state in which a surplus length is added to the span portion 18a to the predetermined length dimension. (Hereinafter, referred to as a long state) so that the state can be changed. And the path | route change part 37 is comprised so that a state change can be performed from a long state to a short state, when rotating the rotary body 32 and winding the adhesive tape 18 around a linear body.

  Here, the path changing unit 37 includes a linear guide 39, a guide unit 38, and an elastic unit 40.

  The linear guide 39 is in a short state along the extension of the straight line while the portion close to the linear body in the span portion 18a (here, the portion between the guide portion 38 and the arcuate guide 32a) is kept in a straight line state. It is provided so that a state change is possible between a long state and a long state. More specifically, the linear guide 39 includes a rail 39a and a slider 39b.

  The rail 39a is provided on the rotating body 32 and is laid in a straight line. Here, the rail 39a is provided so as to extend outward from the rotating body 32 from the opposite side to the wound body support portion 33 with the arcuate guide 32a interposed therebetween. The rail 39a may be laid such that the amount of bending of the extending portion 18a in contact with the arcuate guide 32a is as small as possible. For example, the rail 39a is laid so as to be substantially parallel to a portion extending from the linear body toward the gap portion between the pair of arcuate guides 32a in the extending portion 18a of the adhesive tape 18. It should be noted that slider stops may be provided at both ends of the rail 39a. Here, the rail 39a is provided such that the guide portion 38 bypasses the extending portion 18a in both the short state and the long state. However, the rail 39a may be provided so as not to bypass the span portion 18a in the short state.

  The slider 39b is slidably disposed along the rail 39a. Here, the guide part 38 is provided in the slider 39b.

  The guide portion 38 guides the span portion 18a so as to bypass the span portion 18a. Here, the state change between the first state and the second state is performed by changing the position of the guide portion 38 to change the detour amount of the span portion 18a. Specifically, the guide portion 38 includes a roller 38a that is rotatably supported and guides the span portion 18a while being driven to rotate as the adhesive tape 18 is drawn from the tape winding body 18B. But it is not essential that the guide part 38 contains the roller 38a, and the structure which guides the span part 18a by the member which does not rotate as the guide part 38 may be sufficient.

  The roller 38a is formed in a cylindrical shape, and the portion 18a abuts on the peripheral surface thereof. The roller 38a is rotatably provided on the slider 39b via the support portion 38b, and rotates and sends out when the extending portion 18a moves to the linear body side. This suppresses an increase in the force applied to pull out the adhesive tape 18.

  The roller 38a is provided so that its posture can be changed between a parallel posture in which the central axis direction is parallel to the extending direction of the linear body and an inclined posture in which the central axis direction intersects the extending direction of the linear body. (See FIG. 16). For example, a configuration in which the posture of the roller 38a can be changed by attaching the support portion 38b supporting the roller 38a to the slider 39b so as to be rotatable around an axis orthogonal to the extending direction of the rail 39a by a pin or the like. It is done. At this time, the support portion 38b has a state corresponding to the parallel posture and a state corresponding to the inclined posture with respect to the slider 39b so that the roller 38a can freely change the posture between the parallel posture and the inclined posture. It is conceivable that they are pivotably mounted between them. Note that the maximum value of the inclined posture is, for example, an angle at which the central axis direction of the roller 38a forms approximately 30 degrees with the direction orthogonal to the extending direction of the linear body. However, the roller 38a may be provided so as not to change the posture. In addition, even when the roller changes its posture, it is not essential that the posture can be freely changed between the parallel posture and the inclined posture, and the roller is directed to either the parallel posture or the inclined posture. It may be energized.

  Here, the adhesive tape 18 is disposed so that the adhesive surface faces the roller 38a side. For this reason, the roller 38a is preferably formed of a material to which the adhesive tape 18 is difficult to adhere, or coated on the outer peripheral surface with a material to which the adhesive tape 18 is difficult to adhere. But the adhesive tape 18 may be arrange | positioned so that the adhesive surface may face the opposite side to the roller 38a side.

  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 biases the roller 38a. More specifically, the elastic portion 40 is provided so as to connect one end of the rail 39a and the slider 39b. At this time, the elastic portion 40 is provided on the concave portion 32h side of the rotating body 32 with respect to the slider 39b, and the elastic portion 40 is provided in a slightly compressed state with the slider 39b positioned at the other end of the rail 39a. ing. As a result, the elastic portion 40 urges the slider 39b toward the other end of the rail 39a, and the roller 38a provided on the slider 39b is urged by the elastic portion 40 in the direction in which the extra length increases. . When the slider 39b moves toward one end side of the rail 39a, the elastic portion 40 is compressed more.

  Here, the relationship between the elastic deformation of the elastic portion 40 and the drawing of the adhesive tape 18 from the tape winding body 18B will be described in detail.

  When the rotating body 32 is rotated and the adhesive tape 18 is wound around the linear body, the span 18 a is pulled by the rotation of the rotating body 32. By this pulling, a tension is applied toward the distal end side of the extending portion 18a over the distal end of the extending portion 18a. The tension acts as a force for deforming the elastic portion 40 and a force for pulling out the adhesive tape 18 from the tape winding body 18B. Normally, the tension increases as the rotation of the rotating body 32 increases. Then, when the tension changes, the force with which the span portion 18a presses the elastic portion 40 via the roller 38a changes, whereby the elastic portion 40 is deformed, that is, between the short state and the long state in the path changing portion. A state change in between. Moreover, the said tension | tensile_strength becomes large, and the drawing-out of the adhesive tape 18 from the tape winding body 18B is performed. Moreover, when the said tension | tensile_strength becomes large, it is thought that the winding pressure at the time of winding the adhesive tape 18 around a linear body becomes strong.

  At this time, in order to pull out the adhesive tape 18 from the tape wound body 18B, it is considered that the tension needs to exceed a certain threshold. On the other hand, in the elastic deformation of the elastic part 40, it is considered that the elastic part 40 is successively elastically deformed in a state corresponding to the tension. Therefore, when the tension increases, until the threshold value is exceeded, the elastic portion 40 is mainly elastically deformed from the long state to the short state and the extra length portion of the span portion 18a (long state, short state and path) A portion corresponding to the difference) is wound around the linear body. That is, in this state, the length dimension of the extending portion 18a is gradually shortened.

  And if it continues winding as it is, the said tension will also become large because an elastic force will become large, the said tension will exceed a threshold value and the adhesive tape 18 will be removed from the tape winding body 18B, without deform | transforming the elastic part 40. Transition to the state of withdrawal. In this state, the adhesive tape 18 drawn out from the tape winding body 18B is sequentially wound around the linear body via the span portion 18a. That is, in this state, the length dimension of the extending portion 18a hardly changes.

  Here, as the force related to the deformation of the elastic portion 40, for example, the elastic force of the elastic portion 40, the centrifugal force due to the rotation of the rotating body 32, and the frictional force between the roller 38a and the adhesive tape 18 (roller 38a) The frictional force associated with the rotation of the roller 38a, the frictional force between the slider 39b and the rail 39a, and the like. In addition to the above tension, for example, the adhesive force of the adhesive tape 18 and the frictional force related to the rotation of the wound body support portion 33 can be considered as the force related to the drawing of the adhesive tape 18 from the tape wound body 18B.

  As described above, during the transition from the long state to the short state (transition to reduce the surplus length), the state is the short state after the deformation of the elastic portion 40 stops and rotates at the same speed as during the transition. Compared to the case, the tension is kept small. Thereby, it is considered that the winding pressure applied to the linear body during the transition from the long state to the short state is smaller than the winding pressure applied to the linear body in the short state. At this time, the initial state is set to the long state, and the winding state is shifted from the long state to the short state at the start of winding the adhesive tape 18 around the linear body. The pressure can be reduced. Thereby, the following merit can be obtained.

  That is, here, at the beginning of winding when the adhesive tape 18 is wound around the corrugated tube 16 provided with the slit 17, both ends sandwiching the slit 17 of the corrugated tube 16 are not fixed, so the winding pressure is strong. If it becomes, it will deform | transform so that the said both ends may overlap easily. In particular, here, in order to fix the corrugated tube 16 to the electric wire 12, the tape is wound around the electric wire bundle portion 11 </ b> B first, and then the adhesive tape 18 extending from the electric wire bundle portion 11 </ b> B is passed through the slit 17. The corrugated tube 16 is disposed around the portion of the bundle portion 11B around which the adhesive tape 18 is wound. Then, with the adhesive tape 18 extending from the wire bundle portion 11 </ b> B extending outward of the corrugated tube 16 through the slit 17, the adhesive tape 18 starts to be wound from one of both ends of the corrugated tube 16 sandwiching the slit 17. In such a winding method, if the winding pressure at the beginning of the winding is strong, the one side end that starts winding first will be crushed inward, and if the winding is continued as it is, the other side end will overlap the outside of the one side end. Deformation is likely to occur. On the other hand, even if the other side end portion enters the inside of the one side end portion, the adhesive tape 18 is stretched between the one side end portion and the electric wire 12, so the other side end portion is the one side end. It is thought that it is hard to penetrate inside the part. From the above, if the winding pressure is suppressed at the winding start portion, one end portion of the corrugated tube 16 is not easily crushed inward, so that it is considered easy to suppress the overlap between the one end portion and the other end portion. .

  At this time, the portion of the corrugated tube 16 that has not been wound, that is, the portion where the adhesive tape 18 has already been wound around the corrugated tube 16, is maintained to some extent by the already wound adhesive tape 18. For this reason, even if the winding pressure becomes somewhat strong, it is considered that deformation that causes the end portions to overlap with each other hardly occurs. In particular, when the adhesive tape 18 is wound around both ends sandwiching the slit 17, the shape of the corrugated tube 16 is more reliably maintained by the adhesive tape 18.

  Note that reducing the winding force of the adhesive tape 18 is effective not only when the adhesive tape 18 is wound around the tube-shaped exterior member in which the slit is formed, but also when winding the wire around a wire bundle. This is because if the winding force is too strong, the wire bundle may be greatly swung around the adhesive tape, and the adhesive tape cannot be wound neatly.

  Here, the tape winding mechanism 31 is provided so as to be movable by a tape winding mechanism moving mechanism 46.

  The tape winding mechanism moving mechanism 46 is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and extends in the extending direction of the linear body, that is, in the direction intersecting with the pulling direction of the electric wire 12 (here, (Direction orthogonal). By this tape winding mechanism moving mechanism 46, the tape winding mechanism 31 including the rotating body 32 approaches the linear body along a direction intersecting the extending direction of the linear body (here, a direction orthogonal). It is supported so that it can move or move away. The tape winding mechanism moving mechanism 46 is an example of a rotating body moving mechanism.

  The tape holding portion 41 is a portion that grips a part of the span portion 18a in a state where the adhesive tape 18 is wound around the linear body. In more detail, the tape holding | maintenance part 41 hold | grips the part between the part cut by the tape cut part 49 and the tape winding body 18B among the span parts 18a. Thereby, it is suppressed that the edge part connected to the tape winding body 18B among the both ends of the adhesive tape 18 separated by cutting moves to an undesired direction by the impact of the cut.

  Specifically, the tape holding unit 41 includes a tape gripping mechanism 42 and a tape gripping mechanism moving mechanism 43 that moves the tape gripping mechanism 42 toward the tape. Here, the tape holding unit 41 is provided so as to be movable together with the tape winding mechanism 31 by a tape winding mechanism moving mechanism 46.

  The tape holding portion 41 is a portion that grips a part of the span portion 18a in a state where the adhesive tape 18 is wound around the linear body. In more detail, the tape holding | maintenance part 41 hold | grips the part between the part cut by the tape cut part 49 and the tape winding body 18B among the span parts 18a. Thereby, it is suppressed that the edge part connected to the tape winding body 18B among the both ends of the adhesive tape 18 separated by cutting moves to an undesired direction by the impact of the cut.

  Specifically, the tape holding unit 41 includes a tape gripping mechanism 42 and a tape gripping mechanism moving mechanism 43 that moves the tape gripping mechanism 42 toward the tape. Here, the tape holding unit 41 is provided so as to be movable together with the tape winding mechanism 31 by a tape winding mechanism moving mechanism 46.

  The tape gripping mechanism 42 includes an electromagnetic chuck using a solenoid or a chuck using an air cylinder, and includes a pair of gripping claws 42a that can be opened and closed. Then, by closing the pair of gripping claws 42a closer to the tape winding body 18B than the tape cut portion 49 along the extending direction of the spanning portion 18a, a part of the spanning portion 18a is gripped, and the pair of grips By opening the claw 42a, the grip of the span portion 18a can be released.

  The tape gripping mechanism moving mechanism 43 includes a first horizontal moving mechanism 44 and a second horizontal moving mechanism 45.

  The first horizontal movement mechanism 44 is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and is provided along the moving direction of the tape winding mechanism moving mechanism 46. The first horizontal movement mechanism 44 supports the tape gripping mechanism 42 and the second horizontal movement mechanism 45 so as to be movable along the moving direction of the tape winding mechanism moving mechanism 46.

  The second horizontal movement mechanism 45 is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor. The second horizontal movement mechanism 45 intersects with the movement direction of the first horizontal movement mechanism 44 (here, the extending direction of the linear body). ). The tape holding mechanism 42 is supported by the second horizontal movement mechanism 45 so as to be movable along the extending direction of the linear body.

  Then, in a state where the adhesive tape 18 is wound around the linear body, the tape winding mechanism 31 is separated from the linear body by driving the tape winding mechanism moving mechanism 46, whereby the tape is pulled. At this time, the tape holding part 41 also moves together. Then, by driving the tape gripping mechanism moving mechanism 43, the tape gripping mechanism 42 moves between the portion cut by the tape cut portion 49 in the span portion 18a and the tape winding body 18B. In this state, by closing the pair of gripping claws 42a, it is possible to grip a part of the span portion 18a. Thereby, even if the adhesive tape 18 is cut, the end part connected to the tape winding body 18B can be held. As a result, as will be described later, the extra length of the extending portion 18a can be increased toward the next mounting operation.

  The tape applying portion 47 is a portion that first attaches the tip of the adhesive tape 18 to the linear body when the adhesive tape 18 is wound around the linear body. The tape sticking portion 47 is disposed on the downstream side in the tensile direction with respect to the concave portion 32h of the rotating body 32 set at the winding position. Specifically, the tape applying part 47 includes a pressing part 47a and a pressing part moving mechanism.

  The pressing part 47a includes a pressing surface that presses the adhesive tape 18 directly or indirectly. Here, the pressing portion 47 a presses the adhesive tape 18 via the pressed portion 35 a provided on the rotating body 32.

  The pressing portion moving mechanism is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and is provided along the moving direction of the lifting / lowering moving mechanism 104. By this pressing portion moving mechanism, the pressing portion 47 a is supported so as to be movable along the moving direction of the lifting / lowering moving mechanism 104.

  Then, the pressing portion 47a is moved toward the linear body by driving the pressing portion moving mechanism in a state where the adhesive tape 18 is positioned on the outside of the linear body with the adhesive surface facing the linear body. Thus, the surface of the adhesive tape 18 opposite to the adhesive surface is pressed by the pressing portion 47a via the pressed portion 35a. Thereby, an adhesive surface is affixed on a linear body.

  The tape cut portion 49 is a portion that cuts a part of the span portion 18a in a state where the adhesive tape 18 is wound around the linear body. In more detail, the tape cut part 49 cuts a linear body side rather than the part hold | maintained at the tape holding | maintenance part 41 among the extended parts 18a. The tape cut portion 49 is disposed on the side of the tape applying portion 47. Specifically, the tape cut unit 49 includes a cutting blade 49a and a cutting blade moving mechanism.

  The cutting blade 49a is disposed with the cutting edge facing upward. The cutting blade 49a is formed in a width dimension larger than the width dimension of the adhesive tape 18, for example.

  The cutting blade moving mechanism is constituted by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and is provided along the moving direction of the lifting / lowering moving mechanism 104. By this cutting blade moving mechanism, the cutting blade 49a is supported so as to be movable along the moving direction of the lifting / lowering moving mechanism 104.

  Then, in a state where the adhesive tape 18 is wound around the linear body, the cutting blade 49a is moved toward the span portion 18a by driving the cutting blade moving mechanism, whereby the tape holding portion 41 of the span portion 18a is held. The linear body side is cut from the portion to be cut.

  Next, the clamping unit 90 included in the tape winding unit 30 will be described. Here, the clamping unit 90 supports the linear body with a pair of elastic members 92X that can be deformed into a shape along at least a part of the outer peripheral surface of the linear body (the wire bundle portion 11B and the corrugated tube 16). In this embodiment, when the adhesive tape 18 is wound around the linear body by the sandwiching portion 90, the linear body is held, and the linear body is deformed by twisting or the like due to winding pressure or the like. And the rotation of the linear body or the linear body moving unintentionally are suppressed. The elastic member 92X is a flexible member.

  In the present embodiment, the clamping unit 90 is provided so as to be movable by the tape winding unit moving mechanism 100 together with the tape winding unit 3X. That is, the clamping part 90 is provided so as to be movable with respect to the linear body.

  Moreover, in this embodiment, a pair of elastic member in the clamping part 90 is comprised respectively rotatably, pinching a linear body. Here, as shown in FIG. 5, the clamping unit 90 includes a pair of rollers 92 configured to be rotatable, and an elastic member 92 </ b> X provided on the outer peripheral surface of the pair of rollers 92. Here, the elastic member 92 </ b> X formed in a sheet shape is attached so as to cover the entire outer peripheral surface of the roller 92. For this reason, when the pair of rollers 92 rotates, the elastic member 92X provided on the rollers 92 also rotates.

  In the present embodiment, the clamping unit 90 further includes a support unit 93 that supports the pair of rollers 92 and the elastic member 92X while energizing the pair of rollers 92 and the elastic member 92X in the direction of sandwiching the linear body. Details of each component will be described below.

  In the present embodiment, the roller 92 is formed in a columnar shape, and is attached to the support portion 92B so as to be rotatable around its central axis. For example, the roller 92 is formed so that the diameter gradually decreases toward the intermediate portion. Accordingly, when the linear body is sandwiched between the pair of rollers 92, the linear body can be positioned by being easily positioned at a portion where the diameter is smaller than the pair of rollers 92. . Hereinafter, the portion of the roller 92 formed so that the diameter gradually decreases is referred to as a first portion 921, and the portion of the roller 92 having a constant diameter, that is, the end portion of the roller 92 is referred to as the second portion 922. Called.

  As shown in FIG. 5, the elastic member 92 </ b> X is provided over the entire circumference in the circumferential direction of the outer peripheral surface of the roller 92. Here, the elastic member 92X is fixed to the second portion 922 of the roller 92. Further, the elastic member 92X is provided with a space from the first portion 921 of the roller 92. That is, the elastic member 92X is fixed in the natural state by the second portion 922 of the roller 92, and is provided so that the first portion 921 is spaced from the outer peripheral surface of the roller 92. On the other hand, as described later, when the linear body is sandwiched between the pair of rollers 92 and the elastic member 92X, the elastic member 92X is pressed against the roller 92 side. As a result, the portion of the elastic member 92X that is provided in a natural state and spaced from the first portion 921 of the roller 92 comes into contact with the outer peripheral surface of the first portion 921 of the inner roller 92.

  Here, the elastic member 92X is configured by a member that prevents the linear body from slipping on the contact surface of the elastic member 92X with the linear body in a state where the linear body pulled by the tension mechanism 80 is sandwiched. Has been. For example, if silicon rubber is employed as the elastic member 92X, the linear body is more difficult to slip with respect to the elastic member 92X. Note that the elastic member 92X may be a rubber other than the above.

  Next, the support part 93 will be described. In the present embodiment, the support portion 93 includes an opening / closing drive mechanism 931 and an elastic portion 94. Here, the opening / closing drive mechanism 931 is configured by an electromagnetic chuck using a solenoid, a chuck using an air cylinder, or the like, and includes a pair of opening / closing members 93a that can be opened and closed. A roller 92 is attached to each of the pair of opening / closing members 93a. Then, by closing the pair of opening / closing members 93a in a state where the corrugated tube 16 is positioned between the pair of rollers 92, a part of the corrugated tube 16 is sandwiched and held by the pair of rollers 92, and the pair of opening / closing members 93a. The corrugated tube 16 can be released from being opened. Here, the support portion 92 </ b> B that supports the pair of rollers 92 is attached to the opening / closing member 93 a via the elastic portion 94. Thereby, it can suppress that the force in which a pair of roller 92 pinches a linear body becomes large too much. For example, a coil spring or an air spring may be employed as the elastic portion 94. The elastic portion 94 is biased in the direction in which the pair of rollers 92 approaches.

  Here, as shown in FIG. 5, the support portion 92 </ b> B includes an extending portion 921 </ b> B that extends from the portion on the opening / closing member 93 a side to the opening / closing member 93 a. Further, an insertion hole 939 into which the extending portion 921B can be inserted is formed on the surface of the opening / closing member 93a on the roller 92 side. In the present embodiment, the support portion 92B is attached to the opening / closing member 93a via the elastic portion 94 in a state where the extension portion 921B is inserted into the insertion hole 939. Thereby, it can suppress that the support part 92B shifts in the direction orthogonal to the opposing direction of a pair of roller 92. FIG. As a result, when the linear body is sandwiched between the pair of rollers 92, a state in which the linear body is positioned at the first portion 921 of the pair of rollers 92 can be made stably.

  Moreover, in this embodiment, the clamping part 90 is each provided in the upstream and downstream of the tape winding part 3X in the extension direction of a linear body. Here, a case is shown in which one clamping portion 90 is provided on each of the upstream side and the downstream side of the tape winding portion 3X in the extending direction of the linear body. Hereinafter, the upstream clamping unit 90 is referred to as an upstream clamping unit 901 and the downstream clamping unit 90 is referred to as a downstream clamping unit 902 as necessary.

  In the present embodiment, the downstream clamping unit 902 is provided at a position overlapping the initial position of the connector set unit 86 in plan view and below the connector set unit 86.

  Further, in the present embodiment, the tape winding unit 30 is supported by the tape winding unit moving mechanism 100 so as to be movable between the two attachment units 50, and is a linear body (here, the wire bundle portion 11B). Is supported so as to be able to approach and retract. Thereby, the clamping part 90 and the tape winding part 3X can be moved close to and retracted from the linear body.

<Operation>
Operation | movement of this tube-shaped exterior member attachment apparatus 20 is demonstrated. FIG. 7 is a flowchart when the adhesive tape 18 is spirally wound using the tubular exterior member mounting device 20. 8 to 27 are explanatory views showing the operation of the tubular exterior member mounting device 20. 16, 17, and 21 are explanatory views in which the clamping unit 90 in the tape winding unit 30 is enlarged.

  First, in an initial state, as shown in FIGS. 2 and 8, the operator sets the electric wire module 10 </ b> B and the corrugated tube 16 in the tubular exterior member mounting device 20. More specifically, the middle portion of the two wire bundle portions 11B of the wire module 10B is passed through the wire guide portions 63 of the tube exterior jigs 60 of the two mounting units 50, and the two corrugated tubes 16 are passed through two pieces. It is set in the tube guide part 65 of each tube exterior jig 60 of the attachment unit 50. At this time, one end portion of the corrugated tube 16 is pulled out from the tube guide portion 65, and is mounted on a portion of the wire bundle portion 11B that is pulled out from the wire guide portion 63. In this state, the wire bundle portion 11 </ b> B drawn from the wire guide portion 63 is led into the corrugated tube 16 through the slit 17 at one end side portion of the tube guide portion 65. In this state, the corrugated tube 16 and the wire bundle portion 11B are guided along the tube exterior jig 60.

  Then, the connectors 14 at the ends of the two wire bundle portions 11 </ b> B are set in the connector set portion 86. Further, the middle portion of the portion of the wire bundle portion 11 </ b> B opposite to the connector 14 is passed through the guide groove portion 26. Moreover, the other part of the electric wire 11 with a terminal of the electric wire module 10B is held by the electric wire holding member 22 in a state where the intermediate portion of the electric wire bundle portion 11B is loosened between the guide groove portion 26 and the electric wire holding member 22 (FIG. 2).

  In the initial state, the tape winding unit 30 is in a side position downstream of the wire bundle portion 11 </ b> B in the drawing direction with respect to the tube exterior jig 60 in one attachment unit 50. Moreover, the recessed part 32h of the rotary body 32 is opened in the position toward the electric wire bundle part 11B.

  When the setting of each member is completed, the operator gives a start command to the tubular exterior member mounting device 20 through a start switch or the like.

  Then, in step S1, the tape winding mechanism 31 is moved, the tip of the adhesive tape 18 is attached, and winding of the adhesive tape 18 is started.

  Specifically, as shown in FIG. 8, by driving the tape winding mechanism moving mechanism 46, the tape winding mechanism 31 is on the downstream side in the drawing direction of the wire bundle portion 11 </ b> B with respect to the tube exterior jig 60. Move towards part 11B. As a result, a portion of the wire bundle portion 11 </ b> B that is drawn from the tube exterior jig 60 and that extends from the corrugated tube 16 is disposed at the center of the rotating body 32 of the tape winding mechanism 31.

  When the movement of the tape winding mechanism 31 is completed, the tip of the adhesive tape 18 is pulled out from the tube outer jig 60 and pasted from the corrugated tube 16 in the wire bundle portion 11B. Specifically, as shown in FIGS. 9 and 10, the tip end portion of the adhesive tape 18 is pasted to the wire bundle portion 11 </ b> B by the tape pasting portion 47. More specifically, the pressing portion 47a is moved up by the pressing portion moving mechanism to press the pressed portion 35a. As a result, the pressed portion 35a rotates, the pressing pad 35b attached to the pressed portion 35a presses the adhesive tape 18 positioned above the pressing pad 35b against the wire bundle portion 11B, and the tip of the adhesive tape 18 is the electric wire. Affixed to the bundle portion 11B.

  And the rotation drive part 36 is driven and winding of the adhesive tape 18 around the electric wire bundle part 11B is started.

  In the next step S2, after winding the adhesive tape 18 by a predetermined amount, the winding of the tape is stopped and the corrugated tube 16 is gripped.

  Specifically, the tape winding mechanism 31 rotates the tape winding body 18B by a predetermined amount around the wire bundle portion 11B, whereby the adhesive tape 18 is wound around the wire bundle portion 11B. For example, the adhesive tape 18 is wound around the wire bundle portion 11B about 5 to 6 times. At this time, as shown in FIG. 11, the rotation of the rotation driving unit 36 is performed in a state where the adhesive tape 18 extending from the wire bundle portion 11B is positioned so as to extend downward with respect to the wire bundle portion 11B. Is stopped, and winding of the adhesive tape 18 is interrupted.

  Thereafter, as shown in FIG. 12, the tube gripping mechanism 72 of the tube moving mechanism 70 moves the pair of gripping portions 72 a close to each other to grip the end portion of the corrugated tube 16 that extends from the tube exterior jig 60. . The tube gripping mechanism 72 may grip the corrugated tube while the tape is wound around the wire bundle portion 11B or before the adhesive tape 18 is wound around the wire bundle portion.

  In the next step S3, the corrugated tube 16 is moved. More specifically, as shown in FIG. 13, by driving the horizontal movement mechanism 74, the corrugated tube 16 gripped by the tube gripping mechanism 72 is moved from the tube exterior jig 60 to the downstream side in the drawing direction of the wire bundle portion 11B. The end of the corrugated tube 16 is moved to the position of the tape winding mechanism 31.

  At this time, as shown in FIG. 14, the portion of the adhesive tape 18 wound around the wire bundle portion 11 </ b> B that faces outward from the wire bundle portion 11 </ b> B enters the slit 17 of the corrugated tube 16.

  Here, the path change part 37 changes a state from a long state to a short state in the state which winding to the electric wire bundle part 11B was completed. However, while the rotating body 32 is stopped due to the movement of the corrugated tube 16, the path changing unit 37 draws the adhesive tape 18 from the tape wound body 18 </ b> B by the urging force of the elastic part 40 and is in a long state. Change state to head toward. Thereby, it can move to winding around the corrugated tube 16 in the state which enlarged the extra length of the span part 18a.

  In the next step S4, the holding of the corrugated tube 16 is released, and the winding of the tape is resumed while the corrugated tube 16 is held by the upstream clamping unit 901.

  Specifically, as shown in FIG. 15, the gripping of the corrugated tube 16 by the tube gripping mechanism 72 of the tube moving mechanism 70 is released. Then, the tube gripping mechanism 72 is returned to the initial position by the horizontal movement mechanism 74. Thereafter, as shown in FIG. 16, the pair of rollers 92 are moved close to each other by the opening / closing drive mechanism 931 of the upstream-side clamping unit 901, and the corrugated tubes 16 are held by the pair of rollers 92. In addition, when the state change which the route change part 37 goes to a elongate state is not completed, it is possible that the route change part 37 is changing the state so that it may go to a elongate state also in the meantime.

  The tape winding mechanism 31 rotates the tape winding body 18 </ b> B around the end portion of the corrugated tube 16, so that the adhesive tape 18 is wound around the end portion of the corrugated tube 16. Thus, the winding start part of the adhesive tape 18 is wound around the electric wire bundle part 11B and the one end part of the corrugated tube 16, whereby the one end part of the corrugated tube 16 is fixed to the electric wire bundle part 11B.

  When the adhesive tape 18 starts to be wound around the corrugated tube 16, as described above, the path changing unit 37 changes the state from the state close to the long state to the short state. Thereby, it can suppress that winding pressure becomes too strong in the winding start of the corrugated tube 16. FIG. In addition, after transfering to a short length state, the adhesive tape 18 is pulled out from the tape winding body 18B, and the adhesive tape 18 pulled out from the tape winding body 18B is sequentially wound around the corrugated tube 16 through the span portion 18a. However, the adhesive tape 18 may be pulled out from the tape winding body 18B during the transition from the long state to the short state.

  In the next step S5, pulling of the electric wire 12 and the corrugated tube 16 is started. Specifically, the connector set portion 86 is moved downstream in the pulling direction by driving the pulling drive portion 84 of the wire pulling mechanism 82. As a result, when the connector 14 is pulled downstream in the pulling direction, the wire bundle portion 11B is also pulled downstream in the pulling direction. As described above, since the end portion of the corrugated tube 16 is fixed to the wire bundle portion 11B by the wound adhesive tape 18, when the wire bundle portion 11B is pulled, the corrugated tube 16 also moves together with the wire bundle portion 11B. Be pulled.

  The tape winding mechanism 31 rotates the tape winding body 18 </ b> B around the end of the corrugated tube 16 while pulling the wire bundle portion 11 </ b> B and the corrugated tube 16 by the pulling mechanism 80. Then, the adhesive tape 18 is sequentially wound around the corrugated tube 16 in a spiral manner (see FIG. 18). In addition, the adhesive tape 18 can be tightly wound around the corrugated tube 16 by adjusting the tensile speed of the wire bundle portion 11B and the corrugated tube 16 and the rotational speed of the tape winding body 18B as appropriate. It can also be wound.

  Here, as the adhesive tape 18 is spirally wound around the corrugated tube 16, the roller 38a takes an inclined posture as shown in FIG. Specifically, the corrugated tube 16 is pulled downstream in the tensile direction with the adhesive tape 18 extending from the tape winding body 18 </ b> B being attached to the corrugated tube 16. For this reason, the front-end | tip of the span part 18a is pulled by the pulling direction downstream. In response to this tensile force, the support portion 38b rotates and the roller 38a swings so as to take an inclined posture. At this time, as described above, the roller 38a is provided so as to freely swing within a predetermined range (here, not less than 0 degrees and not more than 30 degrees), so that the roller 38a receives a tensile force and follows the spiral winding. So as to swing. More specifically, for example, when the winding angle is 30 degrees or less, the angle between the extending direction of the portion 18a extending from the tip of the roller 38a and the direction orthogonal to the tension direction is the winding angle. When the wrapping angle is larger than 30 degrees, the roller 38a swings 30 degrees.

  In the next step S6, it is determined whether or not the electric wire has been pulled by a predetermined amount. The predetermined amount of tension to be determined here is the same size as the distance between the tape winding body 18B and the downstream clamping unit 902 along the tension direction. That is, in step S6, it is determined whether or not the downstream end portion of the corrugated tube 16 has been pulled to the extent that it passes through the downstream clamping portion 902 along the pulling direction. If YES is determined, the process proceeds to the next step S7. If NO is determined, the determination is repeatedly made until YES is determined.

  In the next step S <b> 7, the downstream clamping unit 902 holds the corrugated tube 16. Specifically, the pair of rollers 92, the elastic member 92 </ b> X, and the support portion 93 are moved upward by driving the lifting / lowering movement mechanism of the downstream clamping unit 902. Then, in this state, as shown in FIG. 20, the pair of rollers 92 are moved close to each other by the driving of the opening / closing drive mechanism 931 of the downstream clamping unit 902, and the corrugated tube 16 is moved by the pair of rollers 92 and the elastic member 92X. Hold it.

  The upstream clamping unit 901 and the downstream clamping unit 902 hold the corrugated tube 16 between the pair of rollers 92 and the elastic member 92X, thereby preventing the corrugated tube 16 from rotating and the corrugated tube 16 from moving randomly. Play a role. Here, by holding the corrugated tube 16 by the pair of rollers 92 and the elastic member 92X of the upstream clamping unit 901 and the downstream clamping unit 902, it is possible to prevent the corrugated tube 16 from rotating and randomly moving, and the slit The adhesive tape 18 can be wound while 17 is linearly extended. At this time, by holding the corrugated tube 16 on both the upstream side and the downstream side in the tensile direction with respect to the tape winding mechanism 31, it is possible to more effectively suppress the corrugated tube 16 from rotating and being moved in a random manner. . Further, for example, the distance between the upstream clamping unit 901 and the downstream clamping unit 902 and the tape winding unit 3X may be 30 mm to 70 mm. In addition, by arrange | positioning the upstream clamping part 901 and the downstream clamping part 902 in the position as close as possible with respect to the tape winding part 3X, it can suppress more reliably that the corrugated tube 16 rotates and it moves without randomness. . Further, the upstream clamping unit 901 and the downstream clamping unit 902 can also suppress the twist of the corrugated tube 16. Further, the distance between the upstream clamping unit 901 and the tape winding unit 3X and the distance between the downstream clamping unit 902 and the tape winding unit 3X may be the same or different. For example, a case where the distance between the upstream clamping unit 901 and the tape winding unit 3X is smaller than the distance between the downstream clamping unit 902 and the tape winding unit 3X can be considered.

  Further, in this embodiment, as shown in FIGS. 15 to 17, the corrugated tube 16 is a pair of elastic members 92 </ b> X provided on the pair of rollers 92 in a state of being deformed along the outer peripheral surface of the corrugated tube 16. The roller 92 and the elastic member 92X. Since the pair of elastic members 92X that sandwich the corrugated tube 16 tries to return to the original shape (a state spaced from the first portion 921 of the roller 92), the corrugated tube 16 is more stably sandwiched.

  In the present embodiment, the elastic member 92X is deformed into a shape along the outer peripheral surface of the corrugated tube 16, so that the contact area between the outer peripheral surface of the elastic member 92X and the outer peripheral surface of the corrugated tube 16 is increased. Here, as shown in FIG. 17, the elastic member 92X is further deformed along the uneven shape in the extending direction caused by the thick annular portion 16a and the narrow annular portion 16b of the corrugated tube 16. For this reason, the contact area of the corrugated tube 16 and the elastic member 92X can be made larger. As a result, the corrugated tube 16 is more stably clamped by the pair of rollers 92 and the elastic member 92X, so that when the tape winding body 18B is rotated around the end portion of the corrugated tube 16, the corrugated tube 16 is It is possible to effectively suppress rotation and random movement.

  Here, the elastic member 92X is a flexible rubber member. In this case, the corrugated tube 16 can be prevented from sliding on the peripheral surfaces of the pair of elastic members 92X.

  In the next step S8, it is determined whether or not the electric wire has been pulled by a predetermined amount. The predetermined tensile amount to be determined here is a length dimension along the tensile direction of the object on which the tape is wound. That is, in step S8, it is determined whether or not the adhesive tape 18 has been wound by a desired dimension. If YES is determined, the process proceeds to the next step S9. If NO is determined, the determination is repeatedly made until YES is determined.

  Here, as shown in FIG. 20, the adhesive tape 18 will be described as being wound around the other end of the corrugated tube 16 and the wire bundle portion 11B extending from the other end. Is not required. The adhesive tape 18 may not be wound around the wire bundle portion 11B extending from the other end of the corrugated tube 16. At this time, the adhesive tape 18 may be wound up to the other end of the corrugated tube 16 or may be wound up to an intermediate portion of the corrugated tube 16.

  In this embodiment, as shown in FIGS. 20 and 21, when the upstream-side clamping unit 901 clamps the portion of the electric wire 12 (the electric wire bundle portion 11 </ b> B from which the electric wire 12 is exposed), the pair of rollers 92 are provided. The formed elastic member 92X is deformed into a shape along the outer peripheral surface of the wire bundle portion 11B. For this reason, in this embodiment, a contact area with the outer peripheral surface of the wire bundle portion 11B can also be increased, and thereby, the portion of the wire bundle portion 11B where the wire 12 is exposed is stable in the upstream clamping portion 901. And can be pinched. As a result, it can suppress more effectively that a linear body (corrugated tube 16 and the electric wire 12) rotates and moves in a random manner.

  In addition, as shown in FIG. 20, when the downstream clamping unit 902 clamps the corrugated tube 16 around which the adhesive tape 18 is wound, the elastic member 92 </ b> X provided on the pair of rollers 92 is wound with the adhesive tape 18. The corrugated tube 16 is deformed into a shape along the outer peripheral surface. For this reason, the part around which the adhesive tape 18 is wound is also stably held.

  In the next step S9, the pulling of the electric wire is stopped and the winding of the tape is stopped. That is, the driving of the wire pulling mechanism 82 is stopped and the driving of the rotation driving unit 36 is stopped. FIG. 22 shows a state in which the winding of the tape is stopped. As shown in FIG. 22, the posture of the rotating body 32 is adjusted so that the recess 32h and the recess 34h coincide with each other so that the linear body can be discharged from the recess 32h.

  In the next step S10, tape cutting is performed. Further, the clamping state of the clamping unit 90 is also released. Specifically, as shown in FIGS. 23 and 24, the tape winding mechanism 31 is moved away from the wire bundle portion 11 </ b> B by driving the tape winding mechanism moving mechanism 46. Thereby, the adhesive tape 18 is tape-wrapped by separating the tape winding body 18B from the wire bundle portion 11B in a state where the adhesive tape 18 extending from the tape winding body 18B is attached to the wire bundle portion 11B. It is newly pulled out from the body 18B, and the length dimension of the span portion 18a is increased. Furthermore, as shown in FIG. 24, the tape gripping mechanism 42 in which the pair of gripping claws 42 a are open is directed toward the tape by driving the first horizontal moving mechanism 44 and the second horizontal moving mechanism 45 of the tape gripping mechanism moving mechanism 43. Move. At this time, the pair of gripping claws 42 a are moved so as to be positioned in a portion between the tape cut portion 49 and the guide portion 38. Then, in a state where the span 18a is located between the pair of grip claws 42a, the tape grip mechanism 42 closes the pair of grip claws 42a so that the span 18a is gripped.

  Here, it is conceivable that the tape winding unit 30 further includes a linear body movement suppressing unit 48 (see FIGS. 23 and 24). The linear body movement suppressing unit 48 is provided, for example, so as to protrude from the side of the pressing unit 47a of the tape applying unit 47, and is provided so as to be movable integrally with the pressing unit 47a by driving of the pressing unit moving mechanism. More specifically, the linear body movement suppressing portion 48 is provided so as not to interfere with the extending portion 18a of the adhesive tape 18, and the first portion 48a and the first portion 48a projecting laterally from the downstream side of the pressing portion 47a. And a second portion 48b projecting upward from the tip of the first portion. And when the tape winding body 18B leaves | separates from the electric wire bundle part 11B in the state in which the adhesive tape 18 extended from the tape winding body 18B was affixed on the electric wire bundle part 11B, a linear body is a tape winding mechanism. When it is likely to be attracted to 31, the second portion 48b suppresses the movement of the linear body.

  The tape winding mechanism 31 may be moved away from the linear body after the tape gripping mechanism 42 grips the span portion 18a. That is, the tape winding mechanism 31 may be moved away from the linear body in a state where the tip side is supported at a fixed position with respect to the portion to be cut in the span portion 18a.

  Thereafter, as shown in FIGS. 25 and 26, the cutting blade 49a is moved upward by driving the cutting blade moving mechanism, and the portion between the tape holding portion 41 and the wire bundle portion 11B in the span portion 18a is cut.

  Thereafter, when the gripping of the tape gripping mechanism 42 is released, as shown in FIG. 27, the guide portion 38 receives a force that causes the elastic portion 40 to elastically return and moves. Thereby, the length dimension of the adhesive tape 18 from the tape winding body 18B to the part located above the to-be-pressed part 35a becomes large. That is, when the adhesive tape 18 is continuously wound, the extra length can be started in the maximum state. Further, when the elastic portion 40 is elastically restored, the tip end portion of the adhesive tape 18 extending from the tape winding body 18B is positioned above the pressed portion 35a, and the tape can be subsequently applied.

  Then, by releasing the clamping of the upstream clamping unit 901 and the downstream clamping unit 902, the tape winding unit 30 can be moved to the other mounting unit 50 side.

  Then, by driving the tape winding unit moving mechanism 100, the tape winding unit 30 moves to the other attachment unit 50 side, and the adhesive tape 18 is wound around the other corrugated tube 16 in the same manner as described above. Do.

  Finally, each grip and the like on the wire module 10 with the tubular exterior member is released. At this time, it is preferable to lower the tape winding unit 30 and the like so as not to obstruct the removal work of the wire module 10 with the tube-shaped exterior member. And if an operator removes the electric wire module 10 with a tube-shaped exterior member from each attachment unit 50, the electric wire module 10 with a tube-shaped exterior member will be completed. And the connector set part 86 etc. are returned to the original position, and the tubular exterior member attachment apparatus 20 is returned to an initial state.

<Modification>
It is not essential that the adhesive tape 18 is continuously spirally wound from one end to the other end of the corrugated tube 16. For example, the adhesive tape 18 may be partially wound so as to be cut each time it is wound in the respective regions of the one end portion, the intermediate portion, and the other end portion of the corrugated tube 16. In this case, when tape winding is performed on one end portion and the other end portion of the corrugated tube 16, one of the upstream-side sandwiching portion 901 and the downstream-side sandwiching portion 902 sandwiches the electric wire 12, and the other It is conceivable that the corrugated tube 16 is sandwiched. On the other hand, when tape winding is performed on the intermediate portion of the corrugated tube 16, it is conceivable that the upstream-side sandwiching portion 901 and the downstream-side sandwiching portion 902 both sandwich the corrugated tube 16.

  Moreover, although the tape winding apparatus was demonstrated as what was integrated in the tubular exterior member attachment apparatus 20 in embodiment, this is not essential. The tape winding apparatus may be operated alone. At this time, the tape winding device may be provided with a pulling mechanism such as the pulling mechanism 80 that pulls the linear body inserted through the concave portion of the rotating body along the extending direction of the linear body. . For example, a configuration in which a portion obtained by removing the tube exterior jig 60 from the tube-shaped exterior member mounting device 20 is regarded as a tape winding device can be regarded as such a configuration. In this case, the adhesive tape 18 may be wound around the corrugated tube 16 through which the wire bundle portion 11B is inserted in advance using a tape winding device.

  Moreover, in embodiment, although demonstrated in the example which attaches the corrugated tube 16 to the part (1st branch) nearest to one end part with respect to the electric wire bundle part 11B, this is not essential. The corrugated tube 16 may be attached to the other end (second branch) across the branch with respect to the one end of the wire bundle portion 11B.

  Moreover, in embodiment, although demonstrated as what manufactures the electric wire module 10 with a tube-shaped exterior member using the two attachment units 50, this is not essential. For example, you may manufacture another electric wire module with a tubular exterior member using the two attachment units 50, respectively.

  Moreover, although the case where the clamping part 90 was comprised rotatably was demonstrated in embodiment, this is not essential. For example, it may be considered that the linear body is pulled by the pulling mechanism 80 so as to slide between the pinching portions 90 fixed so as not to rotate. Moreover, the case where the linear body is being fixed by the clamping part 90 fixed so that rotation was impossible is also considered. In this case, it is conceivable that tape winding is performed by moving the tape winding part 3X along the extending direction of the linear body with respect to the linear body fixed by the sandwiching unit 90.

  In the embodiment, the sandwiching portion 90 has the configuration in which the elastic member 92X is provided on the outer peripheral surface of the pair of rollers 92, but another mode is also conceivable. For example, the sandwiching unit 90 may include a pair of elastic members formed in a roller shape, that is, a configuration including a pair of rollers formed of an elastic member.

  Further, the relative movement mechanism may be a movement mechanism that moves the tape winding portion 3X along the wire direction of the linear body with respect to the fixed linear body.

  The tape winding device and the tube-shaped exterior member mounting device according to the present invention can be freely combined or implemented within the scope of the invention described in each claim. It is also possible to configure by modifying the form and modification as appropriate or omitting a part thereof.
