{Embodiment}
Hereinafter, the tape winding apparatus according to the embodiment will be described. The tape winding device is a device for winding an adhesive tape around an electric wire whose end is connected to a connector.

<About manufacturing target>
For convenience of explanation, an electric wire module 10 with a tubular exterior member manufactured by a tape winding apparatus will be described with reference to FIG.

  The wire module 10 with a tube-shaped exterior member has a configuration in which a corrugated tube 16 is attached to a wire 12 as a tube-shaped exterior member, and an adhesive tape 18 is wound around the outer periphery.

  Here, the electric wire module 10 with a tube-shaped exterior member includes an electric wire module 10B including a plurality of electric wires with terminals 11 and connectors 14A and 14B, a corrugated tube 16, and an adhesive tape 18.

  The terminal-attached electric wire 11 is configured such that the terminal 13 is connected to the end of the electric wire 12.

  The connectors 14A and 14B are members formed of resin or the like, and a cavity into which the terminal 13 can be inserted and connected is formed inside. The connectors 14A and 14B have different mating connectors as connection destinations, and the outer shape of the connector 14A is different from the outer shape of the connector 14B. That is, the connectors 14A and 14B are manufactured as different types of connectors. Here, the length dimension of the connector 14B is larger than the length dimension of the connector 14A. As the cases where the types of the plurality of connectors are different, there may be cases where the length dimension is different, the width dimension is different, and the protruding shape of the lock shape for maintaining the connection with the mating connector is different.

  Some terminals 13 of the plurality of terminal-attached electric wires 11 are inserted and connected to the connector 14A, and other parts of the terminals 13 are connected to the connector 14B. Thus, the terminal 13 of the some electric wire 11 with a terminal is inserted and connected to connector 14A, 14B, and the one wiring material is comprised. In addition, the other terminal 13 of the some electric wire 11 with a terminal may be in the state which is not connected to connector 14A, 14B.

  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 tube-shaped exterior member-equipped electric wire module 10 is completed by being combined with the other temporary connection so that the terminal 13 that is not connected to the connectors 14A and 14B is inserted and connected to another temporary connector. A form of wire harness is produced.

  In addition, it is not essential that the electric wire module with a tubular exterior member is a temporary structure that constitutes 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 plurality of electric wires 12 extending from the connector 14A are bundled as one electric wire bundle portion 11A. Moreover, the some electric wire 12 extended from the connector 14B is bundled as one electric wire bundle part 11B.

  A corrugated tube 16 as a tube-shaped exterior member is sheathed on each of the wire bundle portion 11A and the wire bundle portion 11B.

  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 portions 11A and 11B while keeping the wire bundle portions 11A and 11B to be protected easily bent. A slit 17 is formed in the corrugated tube 16 along the extending direction (see FIG. 14). The corrugated tube 16 can be attached to the wire bundle portions 11A and 11B by opening the corrugated tube 16 with the slit 17 and inserting the wire bundle portions 11A and 11B inside.

  The pressure-sensitive adhesive tape 18 is formed by forming a pressure-sensitive adhesive layer on one main surface of the belt-shaped resin base material, and is wound around the outer periphery of the corrugated tube 16 with the pressure-sensitive adhesive layer inside. Thereby, the opening of the corrugated tube 16 is suppressed.

  Here, the adhesive tape 18 is wound around both ends of the corrugated tube 16 and the wire bundle portions 11A and 11B extending from the ends. Thereby, the corrugated tube 16 is positioned at a fixed position with respect to the wire bundle portions 11A and 11B. It is not essential that the adhesive tape 18 is wound around the wire bundle portions 11A and 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 tape winding apparatus 20 described later, the adhesive tape 18 is wound around at least the 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 a tube in which the same diameter portion continues along the extending direction.

  In addition, although demonstrated here in the example which attaches the corrugated tube 16 to the wire bundle part 11A, 11B in which the several electric wire 11 with a terminal was bundled, and winds the adhesive tape 18, a corrugated tube is attached with respect to a single electric wire. The same can be applied to the case of attaching and winding an adhesive tape. Further, the present invention can also be implemented when the tubular exterior member is omitted and the adhesive tape is directly wound around the outer periphery of a single or a plurality of electric wires. That is, the mode in which the adhesive tape is wound around the electric wire includes the mode in which the adhesive tape is directly wound around the electric wire, and the mode in which the adhesive tape is wound around the electric wire through a tubular outer member or the like. It is.

<Overall configuration of tape winding device>
The tape winding device 20 is a device for winding the adhesive tape 18 around the corrugated tube 16 while covering the corrugated tube 16 around the wire bundle portions 11A and 11B.

  In particular, in order to wind the adhesive tape 18 around the wire bundle portion 11A, it is necessary to hold and pull the connector 14A, and in order to wind the adhesive tape 18 around the wire bundle portion 11B, the connector 14B is held. It is necessary to pull this. If these operations are performed by separate devices, the number of devices to be installed increases. The tape winding device 20 includes a device for enabling the adhesive tape 18 to be wound around the wire bundle portions 11A and 11B including the electric wires 12 extending from different types of connectors 14A and 14B.

It is a part of. Moreover, when pulling the wire bundle portions 11A and 11B, the adhesive tape 18 can be wound around the outer periphery of the wire bundle portions 11A and 11B or the corrugated tube 16.

  It is not essential that there are two attachment units 50, and only one attachment unit 50 or three or more attachment units 50 may be provided. If a plurality of attachment units 50 are provided, the adhesive tape 18 can be continuously wound around the electric wire set in each attachment unit 50.

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 tape winding 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. Note that some or all of the various processes executed by the control unit 110 may be realized by hardware. Here, the drive timing (conditions), operation details (movement position, movement direction, rotation amount), etc. of each of the above-mentioned drive units are described in the program, and each unit of this apparatus will be described later according to the description of the program.

  The pulling drive unit 84 is an electric wire that extends a tape winding mechanism 31 (to be described later) from the connectors 14A, 14B, etc. set in the connector setting units 86A, 86B, 86C, 86D disposed at the set position S. It is an example of the moving mechanism which carries out relative movement along the extension direction of bundle part 11A, 11B. The moving mechanism may be configured to move the tape winding mechanism 31 along the extending direction of the wire bundle portions 11A and 11B with respect to the wire bundle portions 11A and 11B supported at a fixed position.

  The tube exterior jig 60 includes an electric wire guide portion 63 and a tube guide portion 65.

  The tube exterior jig 60 is formed in, for example, a shape obtained by bending a plate-like member into a substantially U shape. Here, it is assumed that the tube exterior jig 60 is formed in a shape that is obtained by bending a substantially isosceles triangular plate-like member into a substantially U-shape along a vertical bisector of its base. explain.

  A bent portion of the plate-like member is formed in a semi-cylindrical wire guide portion 63 having a substantially U-shaped cross section. This electric wire guide part 63 is comprised so that the electric wire bundle part 11A, 11B inserted in the inside can be guided linearly.

  Moreover, the tube guide part 65 is provided in the outer peripheral part of the both-sides part which pinches | interposes the electric wire guide part 63 among the said plate-shaped members. The tube guide portion 65 is configured to be capable of being externally guided to the wire bundle portions 11A and 11B guided through the wire guide portion 63 while the corrugated tube 16 formed with the slit 17 is widened by the slit 17. ing. For example, both side portions of the plate member sandwiching the wire guide portion 63 are formed in a substantially plate shape having an outer side portion that is inclined with respect to the extending direction of the tube guide portion 65. The outer side portions of the both side piece portions are formed in the flange portion by bending so as to extend outward. The flange portion extends in a direction oblique to the extending direction of the wire guide portion 63, and is provided so as to gradually approach toward the downstream side in the pulling direction of the wire bundle portions 11A and 11B in the wire guide portion 63. It has been. A tube guide portion 65 is configured by the pair of flange portions.

  Then, by inserting the pair of flange portions into the corrugated tube 16 through the slit 17 with the slit 17 expanded, the corrugated tube 16 extends the wire guide portion 63 with the slit 17 expanded. Guided along a direction skewed in the direction.

  And the one end part of the corrugated tube 16 guided by the tube guide part 65 is covered with the part guided through the electric wire guide part 63 among the electric wire bundle parts 11A and 11B and pulled out to the downstream in the pulling direction. In this state, by pulling out the wire bundle portions 11A and 11B and the corrugated tube 16 guided by the wire guide portion 63, the wire bundle portions 11A and 11B are continuously provided in the corrugated tube 16 through the slit 17 widened as described above. Will be inserted. In other words, the tube exterior jig 60 guides the corrugated tube 16 formed with the slit 17 to the wire bundle portions 11 </ b> A and 11 </ b> B guided through the wire guide portion 63 while being widened by the slit 17. .

  As described above, the tube exterior jig 60 supports the connector set portion switching support portion 85 so as to allow the wire bundle portions 11A and 11B to pass on the upstream side in the pulling direction.

  The tube exterior jig 60 is supported at a certain position on the line L and away from the pull driving unit 84 via a support bar 51p and the like.

  The tube moving mechanism 70 is movable in the 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 portions 11A and 11B drawn out from the tube exterior jig 60. It is configured. 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 pulling direction of the wire bundle portions 11A and 11B. By this horizontal movement mechanism 74, the tube gripping mechanism 72 is supported so as to be movable along the pulling direction of the wire bundle portions 11A and 11B via the support portion 74B.

  Then, in a state where the corrugated tube 16 is pulled out to the distal end side of the tube exterior jig 60 together with the wire bundle portions 11A and 11B, the pair of gripping portions 72a of the tube gripping mechanism 72 is closed, so that the end portions of the corrugated tube 16 are It can be gripped. In this state, by driving the horizontal movement mechanism 74, the tube gripping mechanism 72 is moved downstream in the pulling direction of the wire bundle portions 11A and 11B, so that the corrugated tube 16 is downstream in the pulling direction of the wire bundle portions 11A and 11B. It can be moved to. Thereby, as will be described later, the adhesive tape 18 can easily enter the slit 17 of the corrugated tube 16.

<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 in the pulling direction of the wire bundle portions 11 </ b> A and 11 </ b> B with respect to the tube exterior jig 60. When the corrugated tube 16 is pulled out from the tube exterior jig 60 by the pulling unit 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 tape winding mechanism 31 rotates the tape winding body 18 </ b> B around the wire bundle portions 11 </ b> A and 11 </ b> B on the downstream side in the pulling direction by the pull driving unit 84 with respect to the connector setting unit switching support unit 85. The adhesive tape 18 is wound around the wire bundle portions 11A and 11B.

  More specifically, the rotating body 32 is configured such that a U-shaped recess 32h is formed from a part around the outer periphery of the disk-shaped member toward the center. An arcuate guide 32a and a tape pressing portion 35 are provided on one surface side (downstream side in the pulling 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. The adhesive tape 18 is attached to the wire bundle portions 11A and 11B or the corrugated tube 16 by passing the tip side portion of the adhesive tape 18 extending from the tape winding body 18B between the pair of arcuate guides 32a. The tip of the tape 18 is held by the tape pressing portion 35 so as to be positioned at a position where it can be attached to the wire bundle portions 11A and 11B or the corrugated tube 16.

  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 is pressed by a pressing portion 47a of the tape applying portion 47 described later in a state where the tip of the adhesive tape 18 is located between the tape pressing portion 35 and the wire bundle portions 11A, 11B or the corrugated tube 16. The tip of the adhesive tape 18 is pressed toward the wire bundle portions 11A and 11B or the corrugated tube 16 (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 (the surface facing the wire bundle portion 11A, 11B or the corrugated tube 16 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 wire bundle portions 11A and 11B or the corrugated tube 16 side. Thereby, it can suppress that the to-be-pressed part 35a rotates toward the electric wire bundle part 11A, 11B or the corrugated tube 16 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 32h of the rotation body 32 and the position of the recess 34h of the rotation support portion 34 are made to coincide with each other. 11B can be arranged. Further, by rotating the rotating body 32 in this state, the tape winding body 18B can be rotated around the wire bundle portions 11A and 11B disposed in the center of the rotating body 32. It has become.

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

  Then, while pulling out the corrugated tube 16 from the tube exterior jig 60 by the pulling unit 80, the tape winding unit 30 is rotated around the corrugated tube 16 by the tape winding unit 30, 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 portions 11A and 11B so as to wind the tip portion of the adhesive tape 18 around the wire bundle portions 11A and 11B drawn from the tube exterior jig 60, The tip of the adhesive tape 18 can be wound around the wire bundle portions 11 </ b> A and 11 </ b> B outside the one end of the corrugated tube 16. In this state, the corrugated tube 16 is moved with respect to the extending direction of the wire bundle portions 11A and 11B, and the adhesive tape 18 facing outward from the wire bundle portions 11A and 11B is placed in the slit 17 of the corrugated tube 16. In this state, when the tape winding body 18B is rotated around one end portion of the corrugated tube 16, 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 wire bundle portions 11A and 11B and one end portions of the corrugated tube 16, and the one end portion of the corrugated tube 16 and the wire bundle portions 11A and 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. The path changing unit 37 is configured to change the state from the long state to the short state when the rotating body 32 is rotated and the adhesive tape 18 is wound around the wire bundle portions 11A and 11B or the corrugated tube 16. ing. That is, the extra length is generated by changing the state to the long state. When the winding pressure is likely to increase during winding, the extra length is wound around the wire bundle portions 11A and 11B or the corrugated tube 16 by changing the state from the long state to the short state. It suppresses that winding pressure becomes strong.

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

  The linear guide 39 has a portion of the span portion 18a close to the wire bundle portions 11A and 11B or the corrugated tube 16 (here, a portion between the guide portion 38 and the arcuate guide 32a) while maintaining a straight state. It is provided so that a state change is possible between a short state and a long state along an extension line. 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 wire bundle portion 11A, 11B or the corrugated tube 16 toward the gap portion between the pair of arcuate guides 32a in the extending portion 18a of the adhesive tape 18. The 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 span portion 18a moves to the wire bundle portion 11A, 11B or the corrugated tube 16 side. This suppresses an increase in the force applied to pull out the adhesive tape 18.

  The roller 38a has a parallel posture in which the central axis direction is parallel to the extending direction of the wire bundle portions 11A, 11B or the corrugated tube 16, and the central axis direction is the extending direction of the wire bundle portions 11A, 11B or the corrugated tube 16. It is provided so that the posture can be changed between the inclined posture intersecting with (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 may be, for example, an angle at which the central axis direction of the roller 38a forms approximately 30 degrees with the direction perpendicular to the extending direction of the wire bundle portions 11A and 11B or the corrugated tube 16. 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 wire bundle portions 11A and 11B or the corrugated tube 16, the span 18a 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 the wire bundle part 11A, 11B or the corrugated tube 16 becomes strong.

  At this time, in order to pull out the adhesive tape 18 from the tape wound body 18B, it is considered that the tension needs to exceed a certain threshold. On the other hand, in the elastic deformation of the elastic part 40, it is considered that the elastic part 40 is successively elastically deformed in a state corresponding to the tension. Therefore, when the tension increases, until the threshold value is exceeded, the elastic portion 40 is mainly elastically deformed from the long state to the short state and the extra length portion of the span portion 18a (long state, short state and path) The portion corresponding to the difference) is wound around the wire bundle portions 11A and 11B or the corrugated tube 16. 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 wire bundle portions 11A and 11B or the corrugated tube 16 through 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, when the winding pressure applied to the wire bundle portions 11A, 11B or the corrugated tube 16 during the transition from the long state to the short state is smaller than the winding pressure applied to the wire bundle portions 11A, 11B or the corrugated tube 16 in the short state. Conceivable. In this case, the initial state is set to the long state here, and the winding state is shifted from the long state to the short state at the beginning of winding the adhesive tape 18 around the wire bundle portions 11A and 11B or the corrugated tube 16, and therefore the winding is started. The winding pressure applied to the wire bundle portions 11A and 11B or the corrugated tube 16 can be suppressed. 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 portions 11A and 11B, the adhesive tape 18 extending from the electric wire bundle portions 11A and 11B is slit 17. The corrugated tube 16 is disposed around the portion of the wire bundle portions 11A and 11B around which the adhesive tape 18 is wound. Then, with the adhesive tape 18 extending from the wire bundle portions 11 </ b> A and 11 </ b> B extending outward of the corrugated tube 16 through the slit 17, the adhesive tape 18 is wound from one of both ends of the corrugated tube 16 sandwiching the slit 17. Start attaching. 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 electric wire bundle part 11A, 11B or the corrugated tube 16, it is thought that a deformation | transformation force and an attractive force balance in the middle of changing 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 the extending direction of the wire bundle portions 11A and 11B or the corrugated tube 16, that is, the pulling direction of the wire 12 They are arranged along the intersecting direction (here, the orthogonal direction). By this tape winding mechanism moving mechanism 46, the tape winding mechanism 31 including the rotating body 32 is along a direction (here, a direction orthogonal) intersecting the extending direction of the wire bundle portions 11A, 11B or the corrugated tube 16. The wire bundle portions 11 </ b> A and 11 </ b> B or the corrugated tube 16 are supported so as to be able to approach and move apart.

  The tape holding portion 41 is a portion that grips a part of the span portion 18 a in a state where the adhesive tape 18 is wound around the wire bundle portions 11 </ b> A and 11 </ b> B or the corrugated tube 16. 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 is a direction that intersects the movement direction of the first horizontal movement mechanism 44 (here, the wire bundle portions 11A, 11B, or It is provided along the extending direction of the corrugated tube 16. By this second horizontal movement mechanism 45, the tape gripping mechanism 42 is supported so as to be movable along the extending direction of the wire bundle portions 11A and 11B or the corrugated tube 16.

  Then, in a state where the adhesive tape 18 is wound around the wire bundle portions 11A, 11B or the corrugated tube 16, the tape winding mechanism 31 is driven by the tape winding mechanism moving mechanism 46 to turn the tape winding mechanism 31 into the wire bundle portions 11A, 11B or corrugated. The tape is pulled out by being separated from the tube 16. 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.

  When the adhesive tape 18 is wound around the wire bundle portions 11 </ b> A, 11 </ b> B or the corrugated tube 16, the tape applying portion 47 is a portion that first sticks the tip of the adhesive tape 18 to the wire bundle portions 11 </ b> A, 11 </ b> B or the corrugated tube 16. . The tape sticking portion 47 is disposed on the downstream side in the pulling 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 moving mechanism is driven in a state where the adhesive tape 18 is positioned outside the wire bundle portions 11A, 11B or the corrugated tube 16 with the adhesive surface facing the wire bundle portions 11A, 11B or the corrugated tube 16. By moving the pressing portion 47a toward the wire bundle portions 11A, 11B or the corrugated tube 16 by the above, the surface of the adhesive tape 18 opposite to the adhesive surface is pressed by the pressing portion 47a via the pressed portion 35a. The As a result, the adhesive surface is attached to the wire bundle portions 11A and 11B or the corrugated tube 16.

  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 wire bundle portions 11A and 11B or the corrugated tube 16. In more detail, the tape cut part 49 cuts the electric wire bundle part 11A, 11B or the corrugated tube 16 side rather than the part hold | maintained at the tape holding | maintenance part 41 among the span parts 18a. The tape cut portion 49 is disposed on the side of the tape applying portion 47. Specifically, the tape cut unit 49 includes a cutting blade 49a and a cutting blade moving mechanism.

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

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

  Then, in a state where the adhesive tape 18 is wound around the wire bundle portions 11A and 11B or the corrugated tube 16, the cutting blade 49a is moved toward the span portion 18a by driving the cutting blade moving mechanism, so that the span portion 18a Of these, the wire bundle portions 11 </ b> A and 11 </ b> B or the corrugated tube 16 side are cut from the portion held by the tape holding portion 41.

  Here, the tape winding device 20 includes a linear body holding unit 90. The linear body holding portion 90 holds the wire bundle portions 11A, 11B or the corrugated tube 16 when the adhesive tape 18 is wound around the wire bundle portions 11A, 11B or the corrugated tube 16, and the winding pressure or the like. This suppresses deformation such as twisting in the wire bundle portions 11A and 11B or the corrugated tube 16. 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 wire bundle part 11A, 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. As a result, when the wire bundle portions 11A, 11B or the corrugated tube 16 are sandwiched between the pair of rollers 92, the wire bundle portions 11A, 11B or the corrugated tube 16 are positioned at portions where the diameter is smaller than the pair of rollers 92. By becoming easy, the wire bundle portions 11A and 11B or the corrugated tube 16 can be positioned.

  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 | interposes wire bundle part 11A, 11B or the corrugated tube 16 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. As a result, when the wire bundle portions 11A, 11B or the corrugated tube 16 are sandwiched between the pair of rollers 96, the wire bundle portions 11A, 11B or the corrugated tube 16 are positioned at portions where the diameter is smaller than the pair of rollers 96. By becoming easy, the wire bundle portions 11A and 11B or the corrugated tube 16 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 the wire bundle part 11A, 11B or the corrugated tube 16 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>
The operation of the tape winding apparatus 20 will be described. FIG. 6 is a flowchart when the adhesive tape 18 is spirally wound using the tape winding device 20. 7-23 is explanatory drawing which shows operation | movement of the tape winding apparatus 20. FIG.

  First, in the 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 tape winding device 20. Here, it is necessary to wind the adhesive tape 18 around the wire bundle portion 11A and the wire bundle portion 11B of the wire module 10B. First, the adhesive tape 18 is wound around the wire bundle portion 11A. For this reason, the rotary table 85T is appropriately rotated so that the connector set portion 86A is disposed at the set position S corresponding to the line L.

  More specifically, an intermediate portion of the wire bundle portion 11A of the wire module 10B is passed through the wire guide portion 63 of the tube exterior jig 60 of one attachment unit 50, and the corrugated tube 16 is attached to the tube exterior jig of the attachment unit 50. 60 tube guides 65 are set. At this time, one end portion of the corrugated tube 16 is pulled out from the tube guide portion 65 and is covered with a portion drawn out from the wire guide portion 63 in the wire bundle portion 11A. In this state, the wire bundle portion 11 </ b> A 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 11A are guided along the tube exterior jig 60.

  Then, the connector 14A at the end of the wire bundle portion 11A is set in the connector set portion 86A. As a result, the wire bundle portion 11A is set along the line L. The connector 14 </ b> A may be set before or after the wire bundle portion 11 </ b> A is set to the tube exterior jig 60.

  Note that, in the initial state, the tape winding unit 30 is in a side position on the downstream side in the pulling direction of the wire bundle portion 11 </ b> A with respect to the tube exterior jig 60 in one attachment unit 50. Further, the concave portion 32h of the rotating body 32 opens at a position facing the wire bundle portion 11A.

  When the setting of each member is completed, the operator gives a start command to the tape winding 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 downstream of the tube exterior jig 60 in the pulling direction of the wire bundle portion 11A. Move toward part 11A. As a result, the portion of the wire bundle portion 11 </ b> A 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 of the tube outer jig 60 and pasted from the corrugated tube 16 in the wire bundle portion 11A. Specifically, as shown in FIG. 9, the tip end portion of the adhesive tape 18 is pasted to the wire bundle portion 11 </ b> A 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 11A, and the tip of the adhesive tape 18 is the electric wire. Affixed to the bundle portion 11A.

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

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

  Specifically, the tape winding mechanism 31 rotates the tape winding body 18B by a predetermined amount around the wire bundle portion 11A, whereby the adhesive tape 18 is wound around the wire bundle portion 11A. For example, the adhesive tape 18 is wound around the wire bundle portion 11A 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 11A is positioned so as to extend downward with respect to the wire bundle portion 11A. 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 11A 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 gripped by the tube gripping mechanism 72 is moved from the tube exterior jig 60 to the downstream side in the pulling direction of the wire bundle portion 11A. 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> A that faces outward from the wire bundle portion 11 </ b> A 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 wire bundle part 11A 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. In this way, the winding start portion of the adhesive tape 18 is wound around the wire bundle portion 11A and one end portion of the corrugated tube 16, so that one end portion of the corrugated tube 16 is fixed to the wire bundle portion 11A. .

  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 86A is moved to the downstream side in the pulling direction by driving the pull driving portion 84 of the pulling unit 80. As a result, when the connector 14A is pulled downstream in the pulling direction, the wire bundle portion 11A is also pulled downstream in the pulling direction. As described above, since the end portion of the corrugated tube 16 is fixed to the wire bundle portion 11A by the wound adhesive tape 18, when the wire bundle portion 11A is pulled, the corrugated tube 16 also has the wire bundle portion 11A. 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 pulling out the wire bundle portion 11 </ b> A and the corrugated tube 16 by the pulling unit 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 11A 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 pulling direction with the adhesive tape 18 extending from the tape winding body 18 </ b> B being attached to the corrugated tube 16. For this reason, the tip of the span portion 18a is pulled downstream in the pulling direction. 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 formed between the extending direction of the extending portion 18a 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 the electric wire has been pulled by a predetermined amount. The predetermined pulling amount 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 pulling direction. That is, in step S6, it is determined whether or not the downstream end portion of the corrugated tube 16 has been pulled in such an amount that it can pass through the downstream holding portion 95 along the pulling direction. If YES is determined, the process proceeds to the next step S7. If NO is determined, the determination is repeatedly made until YES is determined.

  In the next step S <b> 7, the downstream 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, the twist of the corrugated tube 16 can be more reliably suppressed by holding the corrugated tube 16 both on the upstream side and the downstream side in the pulling direction with respect to the tape winding mechanism 31. 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 pulling 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 portion of the corrugated tube 16 and the wire bundle portion 11A extending from the other end portion. That is not essential. The adhesive tape 18 may not be wound around the wire bundle portion 11 </ b> A 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 tension driving unit 84 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 recesses 32h and the recesses 34h coincide with each other so that the wire bundle portion 11A or the corrugated tube 16 can be discharged from the recesses 32h.

  In the next step S10, the tape is cut and the holding of the linear body holding unit 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> A 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 11A in a state where the adhesive tape 18 extending from the tape winding body 18B is attached to the wire bundle portion 11A. Newly drawn from the body 18B, the length dimension of the span portion 18a is increased. Further, as shown in FIG. 19, by driving the first horizontal movement mechanism 44 and the second horizontal movement mechanism 45 of the tape gripping mechanism moving mechanism 43, the tape gripping mechanism 42 in which the pair of gripping claws 42a are in the open state is used as a 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. When the tape winding body 18B is separated from the wire bundle portion 11A with the adhesive tape 18 extending from the tape winding body 18B being attached to the wire bundle portion 11A, the wire bundle portion 11A or the corrugated tube 16 is removed. Is likely to be attracted to the tape winding mechanism 31, the second portion 48b suppresses the movement of the wire bundle portion 11A or the corrugated tube 16.

  The tape winding mechanism 31 may be moved away from the wire bundle portion 11A or the corrugated tube 16 after the tape gripping mechanism 42 grips the span 18a. That is, the tape winding mechanism 31 may be moved away from the wire bundle portion 11A or the corrugated tube 16 in a state where the distal end side is supported at a fixed position with respect to the portion to be cut in the extending 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 11A in the span portion 18a is cut. .

  Thereafter, when the gripping of the tape gripping mechanism 42 is released, as shown in FIG. 34, 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.

  Thereafter, the holding of the holding portions 91 and 95 of the linear body holding portion 90 is released, so that the corrugated tube 16 is sheathed around the one wire bundle portion 11A of the electric wire module 10B and the adhesive tape 18 is wound thereon. Can be removed from the tape winding device 20. It is preferable to lower the tape winding unit 30 and the like so as not to obstruct the removal work at this time. Further, after the removal work is completed, the connector setting portion 86 and the like are returned to their original positions, and the tape winding device 20 is returned to the initial state.

  By repeating this, the exterior of the corrugated tube 16 and the winding of the adhesive tape 18 can be continuously performed on one wire bundle portion 11A of the plurality of wire modules 10B.

  When the corrugated tube 16 and the adhesive tape 18 are wound around the other wire bundle portion 11B of the wire module 10B, the rotary table 85T is appropriately rotated as shown in FIG. It is assumed that the set portion 86B is disposed at the set position S corresponding to the line L.

  In the same manner as described above, the middle portion of the wire bundle portion 11B of the wire module 10B is passed through the wire guide portion 63 of the tube sheathing jig 60 of one attachment unit 50, and the corrugated tube 16 is attached to the tube sheathing treatment of the attachment unit 50. Set in the tube guide 65 of the tool 60. Further, the connector 14B at the end of the wire bundle portion 11B is set in the connector set portion 86B. As a result, the wire bundle portion 11B is set along the line L.

  When the setting of each member is completed, the operator gives a start command to the tape winding device 20 through a start switch or the like. Thereby, the tape winding mechanism 31 is moved to the position where the wire bundle portion 11B located in the line L is wound by the drive of the tape winding unit moving mechanism 100, and the adhesive tape is similar to the above. 18 winding work is performed. In the same manner as described above, the corrugated tube 16 is sheathed with respect to the wire bundle portion 11B, and the adhesive tape 18 is also wound around the wire bundle portion 11B and the corrugated tube 16.

  By repeating this, the exterior of the corrugated tube 16 and the winding of the adhesive tape 18 can be continuously performed on one wire bundle portion 11B of the plurality of wire modules 10B.

  In addition, after the winding work of the exterior of the corrugated tube 16 and the adhesive tape 18 in one mounting unit 50 and the other mounting unit 50 is set with a wire bundle portion or the like of another wire module, the tape winding is performed. By driving the attached unit moving mechanism 100, the tape winding unit 30 is moved to the other mounting unit 50 side, and in the same manner as described above, the corrugated tube is wrapped around the wire bundle portion and the adhesive tape is wound. May be.

<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, the operator sets the electric wire module 10B and the corrugated tube 16 in the tape winding device 20. In this state, a start command is issued to the tape winding device 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 11A 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, with the adhesive tape 18 extending from the tape winding body 18 </ b> B wound around the corrugated tube 16, the tape winding mechanism 31 is separated from the wire bundle portion 11 </ b> A, so that the adhesive tape 18 becomes the tape winding body. 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 next step S13, the wire bundle portion 11A and the corrugated tube 16 are pulled out by a predetermined amount. Here, the connector set portion 86A is moved downstream in the pulling direction by driving the pulling drive portion 84 so that the next tape winding position in the corrugated tube 16 is positioned at the position of the tape winding mechanism 31 along the pulling 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, with the adhesive tape 18 extending from the tape winding body 18 </ b> B wound around the corrugated tube 16, the tape winding mechanism 31 is separated from the wire bundle portion 11 </ b> A, so that the adhesive tape 18 becomes the tape winding body. 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 11A and the corrugated tube 16 are pulled out by a predetermined amount. Here, the connector set portion 86A is moved downstream in the pulling direction by driving the pulling 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 pulling 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 86A is moved to the downstream side in the pulling direction by driving the pulling drive portion 84, so that the wire bundle portion 11A may be spirally wound.

  In the next step S19, tape cutting is performed. The tape cut is performed in the same manner as in step S10. That is, the adhesive is obtained by separating the tape winding mechanism 31 from the wire bundle portion 11A while the adhesive tape 18 extending from the tape winding body 18B is wound around the corrugated tube 16 or the wire bundle portions 11A and 11B. The tape 18 is newly pulled out from the tape winding 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>

  Further, the moving mechanism moves the connector set portion switching support portion 85 along a predetermined moving direction, so that the connectors set at the connector set portions 86A, 86B, 86C, 86D disposed at the set position S are provided. The tape winding mechanism 31 is positioned at a certain position in the extending direction of the wire bundle portions 11A and 11B because the wire drive includes the pulling drive unit 84 that pulls the wire bundle portions 11A and 11B extending from 14A and 14B along a predetermined movement direction. The tape winding operation can be performed continuously or intermittently on the wire bundle portions 11A and 11B.

  Moreover, since the wire bundle portions 11A and 11B can be pulled while supporting the wire bundle portions 11A and 11B so as to pass through the tube exterior jig 60, when the tape winding is performed, the wire bundle portions 11A and 11B The state is stable and the adhesive tape 18 can be wound as cleanly as possible.

  In addition, since the plurality of connector set portions 86A, 86B, 86C, 86D are moved, one of them is selectively disposed at the set position S, so that the tube exterior jig is moved or provided in plural. The need can be eliminated.

  Moreover, the adhesive tape 18 can be wound around the tube-shaped exterior member while the tube-shaped exterior member is sheathed on the wire bundle portions 11A and 11B by the tube exterior jig 60.
