A tube guide portion that guides the electric wire guided through the electric wire guide portion while being spread out, and is provided on the upstream side in the drawing direction of the electric wire with respect to the tape winding device. An outer jig, and the drawing mechanism sets an electric wire in the electric wire guide part, sets a tubular outer member in the tube guide part, and connects one end of the tubular outer member to the electric wire. The tube-shaped outer member and the electric wire are drawn out from the tube outer jig in a state where the outer portion is extended from the electric wire guide portion, and the tube outer jig is pulled out by the pull-out mechanism. Around said tubular outer member drawn from the jig, by rotating the tape wound body, wrapping the adhesive tape to said tubular outer member around.

  A tube-shaped exterior member mounting device according to a fourteenth aspect is a tube-shaped exterior member mounting device according to a thirteenth aspect, wherein the tubular exterior member is a corrugated structure in which thick annular portions and narrow annular portions are alternately arranged. It is a tube.

  According to the first to fourteenth aspects, a first state in which a portion extending from the tape winding body to the linear body in the adhesive tape is provided in the rotating body and has a predetermined length dimension, and the extending portion is predetermined. It is possible to change the state between the second state in which the extra length is added to the length dimension of the second dimension and when the adhesive tape is wound around the linear body by rotating the rotating body, In order to provide a path changing portion that can change the state to 1, the extra length portion is used instead of pulling out from the tape wound body when the pressure of the adhesive tape is likely to increase when winding the adhesive tape. It can suppress that the winding pressure of an adhesive tape becomes strong too.

  In particular, according to the second aspect, the path changing unit can change the state between the first state and the second state while the portion of the extending portion close to the linear body remains in a straight line state. Since the linear guide provided in is included, the adhesive tape can be wound around the linear body from a desired direction.

  In particular, according to the third aspect, it is possible to suppress an increase in the force required to pull out the tape from the tape winding body supported by the winding body support portion.

  In particular, according to the fourth aspect, the tape winding body takes a parallel posture when, for example, the adhesive tape is partially wrapped around the linear body, and has an inclined posture when it is desired to spirally wind the adhesive tape around the linear body. By taking, the adhesive tape can be wound around the linear body from a desired angle. Thereby, a wrinkle becomes difficult to produce in the adhesive tape wound around the linear body.

  In particular, according to the fifth aspect, the path changing unit includes a guide unit that guides the spanned portion so as to detour the spanned portion, and therefore, when the spanned portion is lengthened, it is possible to suppress an increase in the turning radius. Therefore, the enlargement of the apparatus can be suppressed.

  In particular, according to the sixth aspect, the guide portion includes a roller that is rotatably supported and guides the span portion while being driven and rotated as the adhesive tape is pulled out from the wound body. The force at the time of pulling out an adhesive tape from a tape winding body in the middle of being wound around a linear body can be kept small.

  In particular, according to the seventh aspect, the roller has 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. For example, when the adhesive tape is partially wrapped around the linear body, a parallel posture is taken, and when it is desired to spirally wind the adhesive tape around the linear body, an inclined posture is taken. The adhesive tape can be wound around the linear body from a desired angle. Thereby, a wrinkle becomes difficult to produce in the adhesive tape wound around the linear body.

  In particular, according to the eighth aspect, the path changing unit includes an elastic part that generates an urging force in the direction of increasing the extra length. Therefore, when the tension of the span portion increases as the rotating body rotates, the path changing unit Changes the state from the second state to the first state against the biasing force of the elastic portion. More specifically, the rotation of the rotator causes tension to pull the portion across the tip of the span portion toward the tip side. The tension acts as two forces, a force for pulling out the adhesive tape from the tape winding body and a force for elastically deforming the elastic portion. Then, when the force related to the elastic deformation of the elastic portion is smaller than the force required to pull out the adhesive tape, the path changing portion changes state from the second state to the first state, and the extra length portion of the span portion is a line. Wound around the body. On the other hand, when the force related to the elastic deformation of the elastic portion is larger than the force applied to pull out the adhesive tape, the adhesive tape is drawn from the tape winding body and wound around the linear body. Thereby, the route changing unit can change the state between the first state and the second state without requiring complicated control. Further, when the adhesive tape is wound around the tube-shaped exterior member having the slit by the tape winding device, it is possible to suppress the winding pressure at the beginning of the winding, in which the tube-shaped exterior member is easily deformed, from becoming too strong. .

  In particular, according to the ninth aspect, the adhesive tape further includes a rotating body moving mechanism that moves the rotating body in a direction approaching and separating from the linear body along a direction intersecting the extending direction of the linear body. In the state that is supported at a fixed position on the distal end side of the span portion, the adhesive tape can be pulled out from the tape winding body by moving the rotating body away from the linear body by the rotating body moving mechanism. The state can be reliably changed from the first state to the second state.

  In particular, according to the tenth aspect, since the extra length can be generated in the span portion by stopping the rotation of the rotating body while the adhesive tape is wound around the linear body, the movable range of the apparatus is expanded. While suppressing this, extra length can be generated even during winding. After that, when the rotation of the rotating body is resumed, the winding pressure of the pressure-sensitive adhesive tape is increased by winding the extra length generated when the pressure pressure of the pressure-sensitive adhesive tape is likely to increase. It can be suppressed that it becomes too much.

  In particular, according to the eleventh aspect, since the linear body inserted through the concave portion of the rotating body is further provided with a drawing mechanism that pulls out the linear body along the extending direction of the linear body, it is continuous along the extending direction of the linear body. When the adhesive tape is wound around, or when the adhesive tape is wound around a plurality of positions at intervals along the extending direction of the linear body, the operation related to drawing out the linear body is easily performed. Can do.

  In particular, according to the twelfth aspect, the drawing mechanism allows the tubular exterior member portion to be inserted into the concave portion of the rotating body in the linear body including the tubular exterior member formed with the electrical wire and the slit and sheathed on the electrical wire. In this state, when the adhesive tape is wound around the tubular exterior member, it is possible to suppress overlapping of both end portions sandwiching the slit in the tubular exterior member. it can.

  In particular, according to the thirteenth aspect, the wire guide portion for guiding the wire and the tubular exterior member formed with the slit are spread with the slit, and the wire guided through the wire guide portion is guided so as to be sheathed. A tube outer jig is provided on the upstream side of the wire winding direction with respect to the tape winding device. It can be carried out.

{Embodiment}
Hereinafter, the tape winding apparatus and the tubular exterior member mounting apparatus according to the embodiment will be described. A tape winding apparatus winds an adhesive tape around a linear body by rotating a tape winding body around which the adhesive tape is wound around the linear body. Here, a description will be given assuming that the tape winding device is incorporated in the tubular exterior member mounting device. The tube-shaped exterior member mounting device is a device for mounting a tube-shaped exterior member in which a slit is provided in an electric wire or the like. A tape winding apparatus plays the role which winds an adhesive tape around an electric wire and a tube-shaped exterior member in a tube-shaped exterior member attachment apparatus. That is, here, an electric wire and a tubular exterior member are assumed as the linear body.

<About manufacturing target>
For convenience of explanation, an electric wire module 10 with a tubular outer member manufactured by the tubular outer member mounting device will be described with reference to FIG.

  The wire module 10 with a tube-shaped exterior member is configured such that a corrugated tube 16 is attached to the wire 12 as a tube-shaped exterior member.

  Here, the wire module 10 with a tubular exterior member includes a wire module 10 </ b> B including a plurality of wires 11 with terminals 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. 7). 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. 13). 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 electric wire bundle part 11B where 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. The same can be done when an adhesive tape is wound.

  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 in a spiral shape 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 may be called half-wrap winding). The adhesive tape 18 may be spirally wound with a gap so as not to overlap with 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 attachment device 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.

The horizontal movement mechanism 102 supports the up-and-down movement mechanism 104 and the tape winding unit 30 so as to be movable along the direction connecting the two attachment units 50.

  The elevating / lowering mechanism 104 is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and supports the tape winding unit 30 so as to be movable up and down. Then, the vertical movement mechanism 104 raises the tape winding unit 30 in a state where the vertical movement mechanism 104 is moved below each mounting unit 50 by driving of the horizontal movement mechanism 102, so that the tape winding unit 30 is Ascending and moving upward of the attachment unit 50, the winding operation of the adhesive tape 18 can be performed in each attachment unit 50. Further, the lifting and lowering moving mechanism 104 lowers the tape winding unit 30, so that the tape winding unit 30 is lowered to a position where interference with the mounting unit 50 can be avoided below each mounting unit 50. As a result, the horizontal movement mechanism 102 can horizontally move the lifting / lowering movement mechanism 104 and the tape winding unit 30 below the attachment unit 50.

  The operation control of each part of the tubular exterior member mounting device 20 is performed by the control unit 110. Control unit 110 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.

  The tube exterior jig 60 is preferably detachable from the base plate 51. Thereby, the corrugated tube 16 and the wire bundle portion 11B can be easily set to the tube exterior jig 60.

  The tube-shaped exterior member attachment device 20 includes a tube moving mechanism 70. Here, the tube moving mechanism 70 is provided so as to be movable together with the tape winding unit 30 by the tape winding unit moving mechanism 100. However, the tube moving mechanism 70 may be fixed to the base plate 51.

  The tube moving mechanism 70 is configured to be movable in a direction in which the corrugated tube 16 is pulled out from the tube exterior jig 60 after the tip end portion of the adhesive tape 18 is wound around the wire bundle portion 11 </ b> B drawn out from the tube exterior jig 60. ing. The tube moving mechanism 70 is a mechanism for disposing the adhesive tape 18 at the end of the slit 17.

  That is, the tube moving mechanism 70 includes a tube gripping mechanism 72 and a horizontal moving mechanism 74 that moves the tube gripping mechanism 72 to the side to be pulled out from the tube exterior jig 60.

  The tube gripping mechanism 72 is configured by an electromagnetic chuck using a solenoid or a chuck using an air cylinder, and includes a pair of gripping portions 72a that can be opened and closed. Then, by closing the pair of gripping portions 72a on the distal end side of the tube exterior jig 60, the ends of the corrugated tube 16 drawn out from the tube exterior jig 60 are gripped, and the pair of gripping portions 72a are opened. Thus, the gripping of the corrugated tube 16 can be released.

  The horizontal movement mechanism 74 is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and is provided along the drawing direction of the wire bundle portion 11B. By this horizontal movement mechanism 74, the tube gripping mechanism 72 is supported through the support portion 74B so as to be movable along the drawing direction of the wire bundle portion 11B.

  And the end part of the corrugated tube 16 is hold | gripped by closing the pair of holding part 72a of the tube holding mechanism 72 in the state by which the corrugated tube 16 was pulled out to the front end side of the tube exterior jig | tool 60 with the wire bundle part 11B. be able to. In this state, by driving the horizontal movement mechanism 74, the tube gripping mechanism 72 is moved to the downstream side in the drawing direction of the wire bundle portion 11B, thereby moving the corrugated tube 16 to the downstream side in the drawing direction of the wire bundle portion 11B. Can be done. Thereby, as will be described later, the adhesive tape 18 can easily enter the slit 17 of the corrugated tube 16.

  The drawing mechanism 80 sets the wire bundle portion 11B to the wire guide portion 63, sets the corrugated tube 16 to the tube guide portion 65, and connects one end of the corrugated tube 16 from the wire bundle portion 11B of the wire bundle portion 11B. The corrugated tube 16 and the wire bundle portion 11 </ b> B are configured to be able to be pulled out from the tube exterior jig 60 in a state where the exterior portion is packaged.

  Here, the drawing mechanism 80 includes a wire drawing mechanism 82. The drawing mechanism 80 is provided on the opposite side of the wire holding member 22 with the tube exterior jig 60 interposed therebetween, and is configured to pull the corrugated tube 16 and the wire bundle portion 11B away from the wire holding member 22. Has been.

  The wire drawing mechanism 82 is configured to be able to pull the wire bundle portion 11B by pulling the connector 14 as an end portion attachment member attached to the end portion of the wire bundle portion 11B. 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 drawing mechanism 82 includes a drawing drive unit 84 and a connector set unit 86.

  The drawer drive unit 84 is configured by a linear actuator such as an air cylinder, a hydraulic cylinder, or a linear motor, and is supported on the base plate 51 at a position that is laterally separated from the wire bundle portion 11B. A movable portion 85 that is supported by the drawing drive portion 84 so as to be movable along the extending direction of the wire bundle portion 11B is supported so as to extend from the drawing drive portion 84 toward the wire bundle portion 11B. A 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 drawing mechanism may be configured to pull the electric wire bundle portion 11B while holding the electric wire bundle portion 11B.

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

  It is not essential that the drawing mechanism 80 includes the wire drawing mechanism 82. For example, the pulling mechanism may have a structure including a tube pulling mechanism for pulling out the corrugated tube 16. 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 drawing 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>
FIG. 4 is a schematic plan view showing the tape winding unit 30. FIG. 5 is a schematic front view showing the tape winding unit 30. As shown in FIGS. 3 and 4, the tape winding unit 30 is provided on the downstream side of the wire bundle portion 11 </ b> B in the drawing direction with respect to the tube exterior jig 60. When the corrugated tube 16 is pulled out from the tube exterior jig 60 by the drawing mechanism 80, the adhesive tape 18 can be wound around the corrugated tube 16.

  More specifically, the tape winding unit 30 includes a tape winding mechanism 31, a tape holding unit 41, a tape applying unit 47, and a tape cut unit 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 drawing 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. 9). 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, the tape winding unit 30 is rotated around the corrugated tube 16 by the tape winding unit 30 while the corrugated tube 16 is pulled out from the tube exterior jig 60 by the drawing mechanism 80, 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 end portion of the adhesive tape 18 is wound around the wire bundle portion 11B drawn from the tube exterior jig 60, the adhesive tape 18 The distal end 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 one end part of the wire bundle part 11B and the corrugated tube 16, and the one end part of the corrugated tube 16 and the 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 carried out from a long state to a short state, when rotating the rotary body 32 and winding the adhesive tape 18 around a linear body. That is, the extra length is generated by changing the state to the long state. And, when the winding pressure is likely to increase during winding, the extra pressure is increased by winding the extra portion around the linear body by changing the state from the long state to the short state. Suppress.

  Specifically, 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 value. 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, the adhesive tape 18 is wound around the corrugated tube 16 provided with the slits 17. At this time, since both ends sandwiching the slit 17 of the corrugated tube 16 are not fixed at the start of winding, when the winding pressure is increased, the both ends are easily deformed so as to overlap each other. In particular, here, in order to fix the corrugated tube 16 to the electric wire 12, after the tape is wound around the electric wire bundle portion 11B, the adhesive tape 18 extending from the electric wire bundle portion 11B is passed through the slit 17. The corrugated tube 16 is disposed around the portion of the wire bundle portion 11B around which the adhesive tape 18 is wound. Then, in a state where the adhesive tape 18 extending from the wire bundle portion 11B extends to the outside of the corrugated tube 16 through the slit 17, the adhesive tape 18 starts to be wound from one of both end portions 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.

  From the above viewpoint, it is also effective to wind at the beginning of the winding so that the winding pressure can be suppressed at least one turn slowly and then to increase the rotational speed when winding spirally. it is conceivable that. It is also considered effective that the deformation amount of the elastic portion 40 when shifting from the long state to the short state is set to be larger than at least the outer peripheral dimension of the corrugated tube 16, for example. As a result, at least one round of adhesive tape 18 can be wound around the corrugated tube 16 in a state where the winding pressure is suppressed, and the adhesive tape 18 can be reliably bridged between both ends sandwiching the slit 17. As a result, the corrugated tube 16 is not easily deformed even when the adhesive tape 18 is continuously wound after the transition from the long state to the short state.

  When the rotation of the rotator 32 is stopped, the tension related to winding (tension generated by the rotation of the rotator 32) in the pressure-sensitive adhesive tape 18 is lost, so the tension is reduced. Thereby, the elastic force that has resisted the tension related to winding until now becomes a force that acts in the direction in which the adhesive tape 18 is newly drawn from the tape winding body 18B. If the rotation of the rotating body 32 is stopped due to the fluctuation of these forces, the elastic portion 40 may change its state from the short state to the long state. More specifically, when the deformation force that deforms the elastic portion 40 in the reverse direction is larger than the pulling force, the elastic portion 40 is deformed in the reverse direction while the adhesive tape 18 is pulled out from the tape winding body 18B. . Along with this, the length dimension of the extending portion 18a increases. When the deformation force that deforms the elastic portion 40 in the opposite direction balances the pulling force, the deformation of the elastic portion 40 and the drawing of the adhesive tape 18 from the tape winding body 18B are stopped. Here, when the rotation of the rotating body 32 is stopped, the elastic coefficient of the elastic portion 40 is set so that the elastic portion 40 changes its state from the short state to the long state. In addition, since the front-end | tip of the adhesive tape 18 is affixed on the linear body, it is thought that a deformation | transformation force and a pulling force balance in the middle of shifting from a short state to a long state. Moreover, when the front end of the adhesive tape 18 becomes a free end due to cutting or the like, the elastic portion 40 returns to the initial state, that is, the long state without the adhesive tape 18 being pulled out from the tape winding body 18B.

  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 having the slits but also when winding it around the wire bundle. This is because if the winding force is too strong, the wire bundle may be greatly swung while the adhesive tape is being wound, and the adhesive tape cannot be wound neatly.

  Here, the tape winding mechanism 31 is movably provided 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 direction in which the linear body extends, that is, in the direction that intersects the direction in which the electric wire 12 is drawn (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 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, the tape is pulled out by separating the tape winding mechanism 31 from the linear body by driving the tape winding mechanism moving mechanism 46 in a state where the adhesive tape 18 is wound around the linear body. 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 drawing 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, with the adhesive tape 18 wound around the linear body, the cutting blade 49a is moved toward the span portion 18a by driving the cutting blade moving mechanism, so that the tape holder 41 holds the span portion 18a. The linear body side is cut from the portion to be formed.

  Here, the tubular exterior member mounting device 20 includes a linear body holding portion 90. The linear body holding unit 90 holds the linear body when the adhesive tape 18 is wound around the linear body and suppresses deformation such as twisting of the linear body due to winding pressure or the like. To do. Here, the linear body holding part 90 is demonstrated as what mainly hold | maintains the corrugated tube 16 and suppresses the deformation | transformation. But a holding | maintenance part may hold | maintain the wire bundle part 11B. The linear body holding part 90 is provided so as to be movable by the tape winding unit moving mechanism 100 together with the tape winding unit 30. Specifically, the linear body holding portion 90 includes an upstream side holding portion 91 and a downstream side holding portion 95.

  The upstream holding portion 91 is disposed upstream of the tape winding mechanism 31 and includes a pair of rollers 92 and an opening / closing drive mechanism 93 that drives the pair of rollers 92 to open and close.

  The roller 92 is formed in a cylindrical 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. .

  The opening / closing drive mechanism 93 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 driven to open and close. 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. At this time, 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.

  The downstream holding unit 95 is disposed on the downstream side of the tape winding unit 30 and includes a pair of rollers 96, an opening / closing drive mechanism 97 that opens and closes the pair of rollers 96, and an elevation moving mechanism. The downstream holding portion 95 is provided at a position overlapping the initial position of the connector set portion 86 in plan view and below the connector set portion 86.

  The roller 96 is formed in a cylindrical shape, and is attached to the support portion 96B so as to be rotatable around its central axis. For example, the roller 96 is formed so that the diameter gradually decreases toward the intermediate portion. Accordingly, when the linear body is sandwiched between the pair of rollers 96, the linear body can be positioned at a portion where the diameter is smaller than the pair of rollers 96, whereby the linear body can be positioned. .

  The opening / closing drive mechanism 97 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 97a that can be driven to open and close. A roller 96 is attached to each of the pair of opening / closing members 97a. Then, by closing the pair of opening and closing members 97a in a state where the corrugated tube 16 is positioned between the pair of rollers 96, a part of the corrugated tube 16 is sandwiched and held by the pair of rollers 96, and the pair of opening and closing members 97a. The corrugated tube 16 can be released from being opened. At this time, the support portion 96B that supports the pair of rollers 96 is attached to the opening / closing member 97a via the elastic portion 98. Thereby, it can suppress that the force in which a pair of roller 96 pinches a linear body becomes large too much.

  The up-and-down moving mechanism of the downstream holding unit 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 up-and-down moving mechanism 104. A pair of rollers 96 and an opening / closing drive mechanism 97 are supported by the elevating mechanism so as to be movable up and down along the moving direction of the elevating mechanism 104.

<Operation>
Operation | movement of this tube-shaped exterior member attachment apparatus 20 is demonstrated. FIG. 6 is a flowchart when the adhesive tape 18 is spirally wound using the tubular exterior member mounting device 20. 7-23 is explanatory drawing which shows operation | movement of the tubular exterior member attachment apparatus 20. FIG.

  First, in an initial state, as shown in FIGS. 2 and 7, 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 FIG. 9, 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 around the wire bundle portion 11B by a predetermined amount, 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. 10, the rotation drive unit 36 rotates 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. 11, 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.

  Specifically, as shown in FIG. 12, by driving the horizontal movement mechanism 74, the corrugated tube 16 held by the tube holding mechanism 72 is moved from the tube exterior jig 60 to the downstream side in the drawing direction of the wire bundle portion 11B. Then, 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. 13, 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 (refer FIG. 11). 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. The state is changed so as to go to (see FIG. 13). 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 with the upstream holding portion 91 holding the corrugated tube 16.

  Specifically, as shown in FIG. 14, the gripping of the corrugated tube 16 by the tube gripping mechanism 72 of the tube moving mechanism 70 is released and the tube gripping mechanism 72 is returned to the initial position by the horizontal moving mechanism 74. Thereafter, the pair of rollers 92 are moved close to each other by the opening / closing drive mechanism 93 of the upstream holding unit 91, and the corrugated tube 16 is held by the pair of rollers 92. In the case where the state change of the route changing unit 37 toward the long state is not completed, it is conceivable that the state of the route changing unit 37 is changed so as to go to the long state during this time.

  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. As described above, the winding tape is wound around the wire bundle portion 11B and one end portion of the corrugated tube 16 so that the one end portion of the corrugated tube 16 is fixed to the wire bundle portion 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 shifting 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, the drawing is started.

  Specifically, the connector set portion 86 is moved downstream in the drawing direction by driving the drawing driving portion 84 of the wire drawing mechanism 82. As a result, when the connector 14 is pulled downstream in the drawing direction, the wire bundle portion 11B is also pulled downstream in the drawing direction. As described above, since the end 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 has the wire bundle portion 11B. Pulled with.

  The tape winding mechanism 31 rotates the tape winding body 18 </ b> B around the end portion of the corrugated tube 16 while the wire bundle portion 11 </ b> B and the corrugated tube 16 are pulled out by the drawing mechanism 80. Then, the adhesive tape 18 is sequentially wound around the corrugated tube 16 in a spiral manner (see FIG. 15). In addition, the adhesive tape 18 can be tightly wound around the corrugated tube 16 by adjusting the drawing 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 pull-out direction in a state where the adhesive tape 18 extending from the tape winding body 18 </ b> B is attached to the corrugated tube 16. For this reason, the front-end | tip of the span part 18a is pulled to the drawing direction downstream side. 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 perpendicular to the pulling 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 a predetermined amount of electric wire has been drawn. The predetermined amount of withdrawal determined here is a dimension that is approximately the same as the distance between the tape winding body 18B and the downstream holding portion 95 along the direction of withdrawal. 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 holding portion 95 along the drawing 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 holding unit 95 holds the corrugated tube 16.

  Specifically, the pair of rollers 96 and the opening / closing drive mechanism 97 are moved upward by driving the lifting / lowering mechanism of the downstream holding unit 95. In this state, as shown in FIG. 15, the pair of rollers 96 are moved close to each other by the drive of the opening / closing drive mechanism 97 of the downstream holding unit 95, and the corrugated tubes 16 are held by the pair of rollers 96.

  Each holding part 91 and 95 plays the role which suppresses the twist of the corrugated tube 16 by hold | maintaining the corrugated tube 16 with a pair of roller 92,96. That is, when the adhesive tape 18 is wound around the corrugated tube 16, a force that twists in the winding direction acts on the corrugated tube 16. Therefore, by holding the corrugated tube 16 by the pair of rollers 92 and 96 of the holding portions 91 and 95, the twist of the corrugated tube 16 can be suppressed, and the winding of the adhesive tape 18 is performed while the slit 17 extends linearly. Can be attached. At this time, by holding the corrugated tube 16 both upstream and downstream in the drawing direction with respect to the tape winding mechanism 31, twisting of the corrugated tube 16 can be more reliably suppressed. Furthermore, the twist of the corrugated tube 16 can be more reliably suppressed by disposing the holding portions 91 and 95 as close as possible to the tape winding mechanism 31.

  In the next step S8, it is determined whether or not a predetermined amount of electric wire has been drawn. The predetermined pull-out amount determined here is a length dimension along the pull-out direction of the object on which the tape is wound. That is, in the step S8, it is determined whether or not the adhesive tape 18 is 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. 17, the adhesive tape 18 is described as being wound around the other end of the corrugated tube 16 and the wire bundle portion 11B extending from the other end. That is not essential. The adhesive tape 18 may not be wound around the wire bundle portion 11 </ b> B extending from the other end of the corrugated tube 16. Under the present circumstances, the adhesive tape 18 may be wound to the other end part of the corrugated tube 16, and may be wound to the intermediate part of the corrugated tube 16.

  In the next step S9, the drawing of the electric wire is stopped and the winding of the tape is stopped.

  That is, the driving of the wire drawing mechanism 82 is stopped and the driving of the rotation driving unit 36 is stopped. FIG. 18 shows the state where the winding of the tape is stopped. As shown in FIG. 18, the posture of the rotating body 32 is adjusted so that the concave portion 32h and the concave portion 34h coincide with each other so that the linear body can be discharged from the concave portion 32h.

  In the next step S10, the tape is cut and the holding of the linear body holding part 90 is released.

  Specifically, as shown in FIGS. 19 and 20, 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. Newly drawn from the body 18B, the length dimension of the span portion 18a is increased. Further, as shown in FIGS. 19 and 20, the tape gripping mechanism 42 in which the pair of gripping claws 42a are opened by the drive of the first horizontal moving mechanism 44 and the second horizontal moving mechanism 45 of the tape gripping mechanism moving mechanism 43 is attached to the tape. Move towards. 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 FIG. 20). 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. 21 and 22, 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. 23, the guide portion 38 is moved by receiving the force that the elastic portion 40 is elastically restored. 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.

  After that, by releasing the holding of the holding portions 91 and 95 of the linear body holding portion 90, the tape winding unit 30 can move 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.

<Other operation examples>
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. An example of a flowchart relating to such a winding operation is shown in FIG. In this example of operation, the operation of the holding unit 90 will be omitted. However, the holding unit 90 can hold the corrugated tube 16 during tape winding in the same manner as when the adhesive tape 18 is wound spirally. It is.

  First, in the initial state as in the case of spiral winding, an operator sets the electric wire module 10B and the corrugated tube 16 in the tubular exterior member mounting device 20. In this state, a start command is issued to the tubular exterior member mounting apparatus 20.

  First, in step S <b> 11, the adhesive tape 18 is wound around one end side of the corrugated tube 16. Specifically, the same operations as in steps S1 to S4 are performed, and the adhesive tape 18 is wound around one end of the wire bundle portion 11B and the corrugated tube 16.

  In the next step S12, the tape winding mechanism 31 is moved and the tape is cut. The movement of the tape winding mechanism 31 is performed in the same manner as in step S9, and the tape cutting is performed in the same manner as in step S10. That is, in a state where the adhesive tape 18 extending from the tape winding body 18B is wound around the corrugated tube 16, the adhesive tape 18 is removed from the wire bundle portion 11B by separating the tape winding mechanism 31 from the wire bundle portion 11B. Newly drawn from 18B. By performing tape cutting in this state, it is possible to proceed to the next tape winding step with the extra length at the span portion 18a being maximum.

  In the next step S13, the wire bundle portion 11B and the corrugated tube 16 are pulled out by a predetermined amount. Here, the connector set portion 86 is moved downstream in the drawing direction by driving the drawing driving portion 84 so that the next tape winding position in the corrugated tube 16 is located at the position of the tape winding mechanism 31 along the drawing direction. Let

  In the next step S14, the intermediate portion is wound. Here, after the tape winding mechanism 31 is moved in the same manner as in step S <b> 1, the tip of the adhesive tape 18 is attached to the corrugated tube 16. Thereafter, the rotating body 32 is rotated and the adhesive tape 18 is wound by a predetermined amount.

  In the next step S15, tape cutting is performed. The tape cut is performed in the same manner as in step S10. That is, in a state where the adhesive tape 18 extending from the tape winding body 18B is wound around the corrugated tube 16, the adhesive tape 18 is removed from the wire bundle portion 11B by separating the tape winding mechanism 31 from the wire bundle portion 11B. Newly drawn from 18B. By performing tape cutting in this state, it is possible to proceed to the next tape winding step with the extra length at the span portion 18a being maximum.

  In the next step S16, it is determined whether or not winding of the intermediate portion has been completed. If YES is determined, the process proceeds to the next step S17, and if NO is determined, the process returns to step S13. For example, the adhesive tape may be wound only at one position in the intermediate portion, or the adhesive tape may be wound around a plurality of positions.

  In the next step S17, the wire bundle portion 11B and the corrugated tube 16 are pulled out by a predetermined amount. Here, the connector set portion 86 is moved downstream in the drawing direction by driving the drawing drive portion 84 so that the other end of the corrugated tube 16 is positioned at the position of the tape winding mechanism 31 along the drawing direction.

  In the next step S18, winding on the other end side is performed. Here, after the tape winding mechanism 31 is moved in the same manner as in step S <b> 1, the tip of the adhesive tape 18 is attached to the corrugated tube 16. Thereafter, the rotating body 32 is rotated and the adhesive tape 18 is wound by a predetermined amount. At this time, the connector set portion 86 may be moved to the downstream side in the drawing direction by driving the drawing drive portion 84 to be spirally wound up to the wire bundle portion 11B.

  In the next step S19, tape cutting is performed. The tape cut is performed in the same manner as in step S10. That is, with the adhesive tape 18 extending from the tape winding body 18B wound around the corrugated tube 16 or the electric wire bundle portion 11B, the adhesive tape 18 is separated from the electric wire bundle portion 11B by separating the tape winding mechanism 31. Is newly drawn from the tape wound body 18B. By performing tape cutting in this state, it is possible to proceed to the next tape winding step with the extra length at the span portion 18a being maximum.

  As described above, the electric wire module in which the adhesive tape 18 is partially wound in each of the one end portion, the intermediate portion, and the other end portion of the corrugated tube 16 is completed.

<Effects>
According to the tape winding unit 30 according to the embodiment and the tube-shaped exterior member mounting device 20 including the tape winding unit 30, the rotary body 32 is provided and extends from the tape winding body 18B of the adhesive tape 18 to the linear body. The state can be changed between a first state in which the span portion 18a has a predetermined length dimension and a second state in which the span portion 18a has an extra length added to the predetermined length dimension. When the adhesive tape 18 is wound around the linear body, since the path changing unit 37 that can change the state from the second state to the first state when the adhesive tape 18 is wound around the linear body is provided. When the winding pressure of the tape 18 is likely to become strong, it is possible to suppress the winding pressure of the adhesive tape 18 from becoming too strong by using the extra length portion instead of pulling out from the tape winding body 18B.

  In addition, the path changing unit 37 is a linear unit provided so that the state of the crossing portion 18a that is close to the linear body can be changed between the first state and the second state while maintaining a linear state. Since the guide 39 is included, the adhesive tape 18 can be wound around the linear body from a desired direction.

  Further, since the path changing unit 37 includes the guide unit 38 that guides the span portion 18a so as to bypass the span portion 18a, it is possible to prevent the turning radius from increasing when the length dimension of the span portion 18a is increased. Therefore, the enlargement of the apparatus can be suppressed.

  In addition, the guide portion 38 includes a roller 38a that is rotatably supported and guides the span portion 18a while being driven and rotated as the adhesive tape 18 is pulled out from the tape winding body 18B. The force at the time of pulling out the adhesive tape 18 from the tape winding body 18B while being wound around the body can be kept small.

  Further, the roller 38a can be changed in posture 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. Therefore, for example, when the adhesive tape 18 is partially wound around the linear body, a parallel posture is taken, and when the adhesive tape 18 is spirally wound around the linear body, an inclined posture is taken. Can be wound around the linear body from a desired angle. Thereby, a wrinkle becomes difficult to produce in the adhesive tape 18 wound around the linear body.

  Further, since the path changing unit 37 includes the elastic part 40 that generates a biasing force in the direction of increasing the extra length, when the tension of the span portion 18a is increased by the rotation of the rotating body 32, the path changing unit 37 is elastic. The state is changed from the second state to the first state against the urging force of the unit 40. More specifically, when the rotating body 32 rotates, a tension is generated that pulls the portion 18a toward the distal end side over the distal end of the extending portion 18a. The tension acts as two forces, a force that pulls out the adhesive tape 18 from the tape winding body 18B and a force that elastically deforms the elastic portion 40. When the force related to the elastic deformation of the elastic portion 40 is smaller than the force required to pull out the adhesive tape, the path changing portion 37 changes the state from the second state to the first state, and the extra length of the span portion 18a. The part is wound around the linear body. On the other hand, when the force related to the elastic deformation of the elastic portion 40 is larger than the force applied to pull out the adhesive tape 18 from the tape winding body 18B, the adhesive tape 18 is pulled out from the tape winding body 18B to form a linear body. Wound up. Thereby, the path changing unit 37 can change the state between the first state and the second state without requiring complicated control. In addition, when the adhesive tape 18 is wound around the tube-shaped exterior member having the slit 17 by the tape winding device, it is possible to suppress the winding pressure at the beginning of the winding, in which the tube-shaped exterior member is easily deformed, from becoming too strong. Can do.

  Also, a rotating body moving mechanism (here, a tape winding mechanism moving mechanism 46) that moves the rotating body 32 in a direction approaching and separating from the linear body along a direction intersecting the extending direction of the linear body. In the state where the adhesive tape 18 is supported at a fixed position on the distal end side of the span portion 18a, the rotating body 32 is moved away from the linear body by the rotating body moving mechanism to remove the tape winding body 18B. Since the adhesive tape 18 can be pulled out, the state can be changed more reliably from the first state to the second state.

  Further, when the adhesive tape 18 is wound around the linear body, the extra length of the span portion 18a can be increased by stopping the rotation of the rotating body 32, so that the movable range of the apparatus is prevented from being expanded. However, the surplus length of the span portion 18a can be easily increased. In particular, after winding the adhesive tape 18 around the electric wire 12 first, the extra length of the span 18a can be increased while the rotation of the rotating body 32 is stopped and the corrugated tube 16 is moved to the mounting position. Thereby, after moving the corrugated tube 16 to an attachment position, it can move to a winding operation | work rapidly.

{Modifications}
In the embodiment, the tape winding device is described as being incorporated in the tubular exterior member mounting device 20, but this is not essential. The tape winding apparatus may be operated alone. At this time, the tape winding device may include a drawing mechanism such as the drawing mechanism 80 that draws 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 the span part 18a is pasted on the linear body in the state detoured by the guide part 38, this is not essential. You may affix on the linear body, keeping the whole extending part 18a linear. For example, as shown in FIG. 25, the configuration as described above can be realized by disposing the wound body support portion at the position of the guide portion 38 instead of the guide portion 38. Hereinafter, such a tape winding mechanism 131 will be described in detail with reference to FIGS. 25 to 27. FIG. 25 is a schematic front view showing a tape winding mechanism 131 according to a modification. FIG. 26 is an explanatory diagram showing a state at the time of tape winding in the tape winding mechanism 131 according to the modification. FIG. 27 is an explanatory view showing a state in which the wound body support part 133 changes its posture in the tape winding mechanism 131 according to the modification.

  The tape winding mechanism 131 according to the modification is employed in place of the tape winding mechanism 31 in the tape winding unit 30 according to the embodiment. In the tape winding mechanism 131, the wound body support part 133 is provided on the rotating body 32 via the path changing part 137. Here, the path changing unit 137 is attached to the rotating body 32 via a path changing unit support member 137a. A wound body support part 133 is attached to the path changing part 137.

  More specifically, the path changing unit 137 includes a linear guide 39 and an elastic part 40 in the same manner as the path changing unit 37 of the tape winding unit 30 according to the embodiment. Here, the path changing portion support member 137 a is attached to the rotating body 32. One end of the rail 39a of the linear guide 39 is attached to the path changing portion support member 137a. The other end of the rail 39 a extends in a direction away from the central axis of the rotating body 32. A wound body support portion 133 is attached to a slider 39b that slides along the rail 39a. Then, the adhesive tape 18 extends straight from the tape winding body 18B supported by the winding body support portion 133 toward the wire bundle portion 11B. Accordingly, the path changing unit support member 137 a, the path changing unit 137, and the wound body support unit 133 rotate around the central axis of the rotating body 32 together with the rotating body 32. At this time, the tape winding body 18 </ b> B is located outside the central axis of the rotating body 32 and is supported so as to be able to approach and separate toward the central axis of the rotating body 32. Thereby, also in such a tape winding mechanism 131, as shown in FIG. 26, the elastic part 40 is elastically deformed, whereby the length of the span portion 118a is changed.

  Moreover, in the tape winding mechanism 131, as shown in FIG. 27, the wound body support part 133 is configured so that the tape wound body 18B has a central axis direction of the tape wound body 18B and the extending direction of the wire bundle portion 11B. It supports so that attitude | position change is possible between the parallel attitude | position which becomes parallel, and the inclination attitude | position which a central-axis direction cross | intersects the extension direction of the electric wire bundle part 11B. In FIG. 27, the tape winding body 18 in an inclined posture is indicated by a solid line, and the tape winding body 18B in a parallel posture is indicated by a virtual line (two-dot chain line).

  More specifically, here, the wound body support part 133 includes a first support part 133a and a second support part 133b. The first support portion 133a supports the tape winding body 18B so as to be rotatable at least in the tape feeding direction. The second support portion 133b supports the first support portion 133a. Then, the second support portion 133b is attached to the slider 39b so as to be rotatable around an axis perpendicular to the extending direction of the rail 39a by a pin or the like, so that the first support portion 133a can be rotated around the pin. The Thereby, the attitude | position change of the tape winding body 18B supported by the 1st support part 133a becomes possible between a parallel attitude | position and an inclination attitude | position. At this time, the second support portion 133b is parallel to the slider 39b so that the tape winding body 18B supported by the first support portion 133a can freely change its posture between the parallel posture and the inclined posture. It is conceivable that it is rotatably attached between a state corresponding to the posture and a state corresponding to the inclined posture.

  The tape wound body 18B supported by the wound body support part 133 has two inclined postures, that is, a first inclined posture that is inclined to one side with respect to the parallel posture as in the inclined posture shown in FIG. It is conceivable to adopt a second inclined posture inclined to the opposite side of the inclined posture shown in FIG. 27 with respect to the parallel posture. It is conceivable that the maximum value of the first inclined posture is, for example, a posture inclined 45 degrees from the parallel posture. In addition, the maximum value of the second inclined posture is, for example, a posture inclined by 15 degrees from the parallel posture. In order to regulate the inclination posture in this way, for example, a regulation unit that regulates the rotation of the first support part and the second support part by contacting the first support part or the second support part is provided. It is also possible.

  But the tape winding body 18B supported by the 1st support part 133a may be provided so that a posture change may not be carried out. Further, even when the tape winding body 18B supported by the first support portion is changed in posture, it is not essential that the posture can be freely changed between the parallel posture and the inclined posture, and is supported by the first support portion. The tape winding body 18B may be biased toward either one of the parallel posture and the inclined posture.

  It is preferable that the path changing portion 137 and the wound body support portion 133 are provided so that the extending direction of the rail 39a of the linear guide 39 is parallel to the extending direction of the extending portion 118a. Thereby, the force required to pull out the adhesive tape 18 from the tape wound body 18B supported by the wound body support part 133 can be kept small.

  According to such a tape winding mechanism 131, since the span portion 118a is straight, the force required to pull out the adhesive tape 18 from the tape winding body 18B supported by the winding body support portion 133 is kept small. Can do.

  Further, the tape winding body 18B takes a parallel posture when, for example, the adhesive tape 18 is partially wound around the wire bundle portion 11B, and takes an inclined posture when it is desired to spirally wind the adhesive tape 18 around the wire bundle portion 11B. Thus, in each winding mode, the adhesive tape 18 can be wound around the wire bundle portion 11B from a desired angle. Thereby, wrinkles are less likely to occur in the adhesive tape 18 wound around the wire bundle portion 11B.

  In the embodiment, the path changing unit 37 has been described as being changeable between the first state and the second state by the elastic unit 40, but this is not essential. For example, the state may be changed between a first state and a second state by an actuator such as an air cylinder. In this case, the state can be changed at a desired time by controlling the actuator. For example, the state can be changed from the first state to the second state even while the rotating body 32 is rotating. In this case, similarly to the above, the extra length can be fed to reduce the winding force.

  Further, in the embodiment, the path changing unit 37 includes the first state and the first state along the extension of the straight line while the portion between the guide part 38 and the linear body in the extended portion 18a is kept in a straight state. Although the linear guide 39 provided so that a state change is possible between 2 states is included, this is not essential. For example, a guide that allows the state of the guide portion 38 to be changed between a first state and a second state along a curved line may be included.

  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.

  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.
