It is like that.

[Operation of tape winding device]
Hereinafter, the operation of the tape winding apparatus 1 will be described. The operation of the tape winding device 1 includes a first winding operation in which the tape T is wound spirally around the electric wire portion W1 of the wire harness W, and a second winding operation in which the tape T is wound spirally around the outside of the corrugated tube C. And an exterior member attaching operation for attaching the corrugated tube C to the outside of the electric wire portion W1, and each operation is sequentially or simultaneously executed by the tape winding device 1. In addition, in each operation | movement, unless it demonstrates in particular, each part of an apparatus shall be controlled by the apparatus control part 5, and shall be drive | operated automatically or semi-automatically.

  As an operation process common to the first winding operation and the second winding operation, a drawing step (drawing operation) for drawing out the feeding-side end portion T1 from the roll-shaped tape T supported by the tape support portion 50, and drawing out. A sticking step (sticking operation) for sticking the feeding-side end T1 of the tape T to the electric wire portion W1 or the corrugated tube C, and a winding step (tape winding) for winding the tape T around the electric wire portion W1 or the corrugated tube C. And a cutting step (cutting operation) for cutting the tape T wound around the electric wire portion W1 or the corrugated tube C.

  As shown in FIG. 10, in the drawing process, the turning means 40, the sticking means 60, and the cutting means 70 are in the retracted position, that is, the tape T of the tape support 50 is in the Y direction more than the electric wire portion W1 and the corrugated tube C. It is executed in a state located on the far side. First, as shown in FIG. 12, the sticking means 60 pushes the sticking support plate 62 toward the front side in the Y direction by the air cylinder 63 and moves the sticking head 66 to the sticking position above the tape T.

  Next, as shown in FIG. 13, the lifting plate 64D is pushed down by the air cylinder 64A, and the gripping head 66 is lowered to a gripping position in contact with or close to the tape chuck 54. Then, as shown in FIG. A pair of gripping members 66C are brought close to each other by an air cylinder in the main body 66A to grip the feeding-side end portion T1 of the tape T. Thereafter, while holding the feeding-side end portion T1 with the pair of gripping members 66C, the lifting plate 64D is pulled up by the air cylinder 64A and the gripping head 66 is raised to the drawing position as shown in FIG. Pull out the end T1.

  The sticking step is executed following the pulling step. From the state in which the gripping head 66 of the sticking means 60 pulls out the feeding side end T1 of the tape T, the air cylinder 24 of the base 20 is moved to the slide plate as shown in FIG. 23 is pushed toward the front side in the Y direction, so that the turning means 40 is moved to the winding position, the sticking means 60 and the cutting means 70 are also advanced, and the sticking head 66 is positioned above the electric wire portion W1 or the corrugated tube C. To move. By this movement, as shown in FIG. 17, the adhesive surface of the drawn tape T is pressed against the side surface of the electric wire portion W1 or the corrugated tube C, and a part of the tape T is affixed. Thereafter, the grip head main body 66A releases the grip of the tape T by separating the pair of grip members 66C.

  Next, as shown in FIGS. 18 and 19, the tape pressing unit 65 pushes the pressing head 65F by the air cylinder 65A and moves it to the pressing position. As the pressing head 65F moves, the roller 65G abuts on the tape T and rolls from the side surface of the electric wire portion W1 or the corrugated tube C to the upper surface. The roller 65G rolls the tape T to the electric wire portion W1 or corrugated. The tube C is pressed and the feeding side end T1 of the tape T is stuck. Thereafter, as shown in FIG. 20, the sticking means 60 pulls back the sticking support plate 62 toward the back in the Y direction by the air cylinder 63, and retracts the sticking means 60 and the cutting means 70 from the turning means 40.

  The winding step is executed following the sticking step, and the turning means 40 is driven to rotate as shown in FIG. 21 from the state where the feeding side end T1 of the tape T is stuck to the electric wire portion W1 or the corrugated tube C. The rotating motor 46 of the means 45 is driven to rotate the driven gear 49 and the rotating plate 44. By the rotation of the rotating plate 44, the tape T supported by the tape support portion 50 turns clockwise when the periphery of the electric wire portion W1 or the corrugated tube C is viewed from the upstream side.

  Thus, when the tape T is swung by the swiveling means 40, the main body drive unit 4 moves the base 10 of the head unit 3 to the X direction downstream side by a linear motor at the same time or after a predetermined time. By the movement of the head portion 3, the tape T is relatively moved toward the downstream side in the longitudinal direction of the electric wire portion W <b> 1 or the corrugated tube C while being turned by the turning means 40, and spirally formed on the electric wire portion W <b> 1 or the corrugated tube C. It will be wound. When the winding of the tape T by the predetermined length is completed, the main body drive unit 4 stops driving the linear motor to stop the movement of the head unit 3, and the turning means 40 stops driving the rotary motor 46 and rotates. The rotation of the plate 44 is stopped.

  The stop position of the rotary motor 46 is controlled by the sensor 57 shown in FIG. 8 detecting the detected portion 56, and the tape T is positioned below the electric wire portion W1 and the corrugated tube C as shown in FIGS. At the same time, the rotation motor 46 is stopped driving so that the notches 44A and 49A of the rotating plate 44 and the driven gear 49 are in the same direction as the notches 41A and 42A of the support plate 41 and the counter plate 42. Therefore, in the state where the rotation of the tape T is stopped, as shown in FIG. 23, the winding excess length portion T2 of the tape T from the electric wire portion W1 or the corrugated tube C toward the lower tape chuck 54 from the Y-direction back side surface is It will be in the extended state.

  The cutting step is executed following the stop of the rotation motor 46 in the winding step, and the cutting means 70 pushes the cutting head 72 by the air cylinder 71 and moves it to the cutting position as shown in FIG. By the movement of the cutting head 72, the regulating member 74 sinks below the electric wire portion W1 or the corrugated tube C, supports the electric wire portion W1 or the corrugated tube C from below, and the cutting blade 73 has an excess winding length of the tape T. Cut into the part T2 and cut. Further, the distal end portion of the cutting head 72 enters under the electric wire portion W1 or the corrugated tube C, and the winding excess length portion T2 of the cut tape T is pressed from the side surface of the electric wire portion W1 or the corrugated tube C to the lower surface side. Affix it.

  When the winding excess length portion T2 of the tape T is cut with the cutting blade 73 in this way, a feeding-side end portion T1 of the tape T is formed below the cut portion. The feeding side end T1 tends to be pulled back to the lower roll portion by the tension and gravity of the tape, but the second holding member 54C of the tape chuck 54 is rotated by this pulling back movement, and the first holding member 54A. The tape T is clamped by closing the gap between the first holding member 54C and the second holding member 54C. As a result, the feeding-side end T1 of the tape T is held in a state of protruding upward from the tape chuck 54 as shown in FIG. Thereafter, the cutting means 70 pulls the cutting head 72 back toward the back in the Y direction by the air cylinder 71 and moves it to the retracted position below the partition plate 75.

[First winding operation and exterior member mounting operation]
In the tape winding device 1 of the present embodiment, a first winding operation for spirally winding the tape T around the electric wire portion W1 of the wire harness W, an exterior member attaching operation for attaching the corrugated tube C to the outside of the electric wire portion W1, Are executed simultaneously.

  Prior to the first winding operation, a preparation process is executed. This preparation process is performed by the operator in a state in which each part of the tape winding apparatus 1 is returned to the initial position. As shown in FIGS. 1 and 2, the initial position of the head unit 3 is a position near the sub operation unit 5 </ b> C on the upstream side of the wiring board 10, and the case cover 32 of the case 30 is opened at the initial position of the head unit 3. Then, the turning means 40, the pasting means 60, the cutting means 70, and the supply means 80 are retracted to the retracted position. Further, in the wiring device 2, the plurality of wiring jigs 12 are in a state of protruding from the upper surface of the wiring board 10, and the holding unit 90 of the supply unit 80 is immersed downward from the upper surface of the wiring board 10. It is in a state.

  In the preparation step, first, the tape T is set on the tape support portion 50 of the head portion 3, and the feeding side end portion T1 is held by the tape chuck 54 and protrudes upward. Further, the wire harness W is placed on the wiring board 10, the connector W <b> 2 is fitted to the connector holding portion 11, and the electric wire portion W <b> 1 is locked to the locking claws 13 of the plurality of wiring jigs 12. Further, the electric wire portion W <b> 1 is inserted through the notch of the insertion member 35 </ b> A of the case body 31 in the electric wire insertion portion 35 of the case 30. A corrugated tube C is prepared on the front side of the wiring board 10.

  When the above preparation process is completed, the operator operates the switch of the control operation unit 5B to start the first winding operation. The control unit main body 5A that has received the signal from the switch closes the case lid 32 by the air cylinder 33 of the case 30, and then, with respect to the wire portion W1 in the vicinity of the connector W2 on one end side (upstream side) of the wire harness W, After performing the drawing process and the pasting process, the winding process is performed toward the downstream side of the electric wire portion W1. In this winding step, the moving speed of the head part 3 by the linear motor of the main body driving part 4 is set to be relatively high compared to the turning speed of the tape T by the turning means 40, and thereby the electric wire part W <b> 1. As shown in FIG. 26, the tape T is wound in a rough spiral shape that does not overlap each other.

  When the control unit main body 5A winds the tape T around the electric wire portion W1 by a predetermined length, the control unit main body 5A simultaneously stops the linear motor of the main body drive unit 4 and the rotation motor 46 of the turning means 40, and interrupts the winding process. In this interrupted state, as shown in FIG. 27, the control unit body 5A advances the slide member 84, the clamp member 87, and the insert 88 by the air cylinder 85 of the supply means 80, and the rotating roller 86 is moved to the electric wire portion W1. While moving to the abutting position and causing the holding portion 90 of the supply means 80 to protrude from the upper surface of the wiring board 10, each portion is stopped to enter a standby state (waiting for an input signal).

  In the standby state, the operator performs an exterior member setting process for setting the corrugated tube C to the supply means 80. First, as shown in FIG. 28, the clamp member 87 is rotated, and the insert 88 is positioned along the electric wire portion W1 to be in the guide state, and the concave portion 885, the second member 88C, and the third member of the first member 88B. The electric wire portion W1 is inserted into the recess of 88D. Next, as shown in FIG. 29, the prepared corrugated tube C is inserted into the guide portion 89, and the protrusion 881 of the inserter 88 is inserted at the tip thereof, as shown in FIGS. The corrugated tube C is put on the insert 88 while opening the slit C1. Further, the corrugated tube C is pushed upstream, the electric wire portion W1 is inserted into the corrugated tube C through the slit C1, and the corrugated tube C is attached to the outside of the electric wire portion W1 at an upstream portion from the inserter 88, The end portion is placed on the chuck portion 92 of the holding portion 90.

  When the setting of the corrugated tube C is completed in this manner, the operator operates the switch of the sub operation unit 5C to transmit an exterior member setting process completion signal to the control unit main body 5A. As shown in FIG. 34, the control unit main body 5A that has received the exterior member setting process completion signal causes the chuck part 92 of the holding part 90 to grip the corrugated tube C, and then restarts the winding process, so that the electric wire portion W1 While winding the tape T in a spiral shape, the corrugated tube C is attached to the electric wire portion W1. That is, the winding process and the exterior member attaching process are executed simultaneously.

  Specifically, while turning the tape T around the electric wire portion W1 by the turning means 40, the electric wire portion W1 is moved relative to the downstream side of the electric wire portion W1 by the linear motor of the main body drive unit 4. While the tape T is wound in a spiral shape, the corrugated tube C is guided by relatively moving the insert 88 and the guide portion 89 of the supply means 80 to the downstream side of the electric wire portion W1 as the head portion 3 moves. The electric wire portion W1 is supplied toward the electric wire portion W1, inserted into the corrugated tube C through the slit C1 opened by the inserter 88, and the corrugated tube C is sequentially attached toward the downstream side of the electric wire portion W1.

  In the winding process and the exterior member mounting process in the first winding operation and the exterior member mounting operation, the control unit main body 5A does not disturb the movement of the head unit 3 and the jig driving unit of the wiring apparatus 2 14, the wiring jig 12 is sunk downward from the upper surface of the wiring board 10, and after passing through the head portion 3, the wiring jig 12 is protruded from the upper surface of the wiring board 10, and again the electric wire portion W <b> 1 and the corrugation Tube C is supported. Thus, when the head portion 3 passes, the support of the electric wire portion W1 by the wiring jig 12 is temporarily released, but the electric wire portion W1 and the corrugated tube C are placed in the electric wire insertion portion 35 of the case 30. Since it is inserted and supported, the sagging is prevented and a sticking process, a winding process, and a cutting process are appropriately performed.

  As described above, when the winding of the tape T around the electric wire portion W1 is completed over a predetermined length, the control unit main body 5A stops the linear motor of the main body drive unit 4 and the rotation motor 46 of the turning means 40. Then, the winding process and the exterior member attaching process are completed. Next, the control unit main body 5 </ b> A performs a cutting process in which the tape T is cut by the cutting means 70, and then opens the case cover 32 by the air cylinder 33 of the case 30 and slides by the air cylinder 24 of the base 20. After turning the turning means 40, the attaching means 60, and the cutting means 70 together with the plate 23 to the retracted position, the respective parts are stopped to enter a standby state.

  In the standby state, the operator removes the insert 88 of the supply means 80 from the electric wire portion W1 and the corrugated tube C, and performs an exterior member finishing process for manually attaching the other end of the corrugated tube C to the electric wire portion W1. . First, the corrugated tube C is removed from the insert 88, and the clamp member 87 is rotated to separate the insert 88 from the electric wire portion W1 to release the guide state. Further, the other end side is covered with the electric wire portion W1 through the slit C1 of the corrugated tube C, and the corrugated tube C is attached to the electric wire portion W1 over the entire length thereof.

  When the attachment of the corrugated tube C is completed in this manner, the operator operates the switch of the sub operation unit 5C to transmit an exterior member finishing process completion signal to the control unit main body 5A. The control unit main body 5A that has received the exterior member finishing process completion signal causes the air cylinder 85 of the supply means 80 to retract the slide member 84, the clamp member 87, and the inserter 88 to the retracted position, and also by the chuck unit 92 of the holding unit 90. The holding | maintenance of the corrugated tube C is cancelled | released, and the holding | maintenance part 90 is immersed below from the upper surface of the wiring board 10. FIG. Further, the control section main body 5A returns the head section 3 to the initial position by the linear motor of the main body drive section 4, and then stops each section and enters a standby state.

  Thus, the first winding operation and the exterior member attaching operation by the tape winding device 1 are completed. Subsequently, the second winding operation is performed.

[Operation with volume 2]
The second winding operation by the tape winding device 1 of the present embodiment is an operation of winding the tape T around the corrugated tube C so as to overlap each other by about a half width, thereby closing and protecting the slit C1 of the corrugated tube C. The performance is ensured and the wire harness W with the corrugated tube C is completed. Here, a clamp for fixing the vehicle is attached to the corrugated tube C at a plurality of positions at an appropriate interval in a subsequent process, and the tape T is set so as not to be wound around the clamp attaching position. That is, in the second winding operation, a winding operation (winding step) in which the tape T is wound around a predetermined range along the longitudinal direction of the corrugated tube C to form a tape winding portion, and an adjacent tape winding portion. The non-winding operation for forming the non-winding portion around which the tape T is not wound is alternately executed.

  For the tape winding device 1 that has returned to the initial position and is in a standby state, the operator operates the switch of the control operation unit 5B to start the second winding operation. The control unit body 5A that has received a signal from the switch closes the case cover 32 by the air cylinder 33 of the case 30 and then performs a drawing process and a pasting process on the upstream end of the corrugated tube C. The winding step is performed toward the downstream side. In this winding process, the moving speed of the head portion 3 with respect to the turning speed of the tape T is set to be relatively low compared to the winding process of the first winding operation. T is wound in a spiral shape that overlaps each other by about a half width.

  When the control unit main body 5A winds the tape T around the electric wire portion W1 by a predetermined length to form the tape winding portion, the control unit main body 5A simultaneously stops the linear motor of the main body driving unit 4 and the rotation motor 46 of the turning means 40, thereby winding operation. The (winding step) is terminated.

  Following the winding operation, the control unit main body 5A executes a non-winding operation. This unwinding operation is performed in the order of a cutting process, a moving process, a drawing process, and a pasting process. Specifically, after the cutting step of cutting the tape T by the cutting means 70 is executed, a moving step of moving the tape T downstream by a distance corresponding to the length of the non-winding portion is executed. In this moving process, the turning means 40, the pasting means 60, and the cutting means 70 are retracted to the retracted position by the air cylinder 24 of the base 20, and the head part 3 is moved downstream in the X direction by the linear motor of the main body driving part 4. . After moving the tape T to the downstream side by a distance corresponding to the length of the non-winding part by such a moving process, the control unit main body 5A executes the drawing process and the pasting process to move the non-winding part. Once formed, the non-winding operation is terminated.

  Thereafter, the control unit main body 5A alternately performs the winding operation (winding step) and the non-winding operation so that the tape winding portion and the non-winding portion are alternately arranged along the longitudinal direction of the corrugated tube C. To form. When the tape winding portion is formed by the winding operation to the downstream end portion of the corrugated tube C, the control unit main body 5A stops the linear motor of the main body driving unit 4 and the rotation motor 46 of the turning means 40, and the cutting means 70 A cutting process for cutting the tape T is executed. Further, the case lid 32 is opened by the air cylinder 33 of the case 30, and the turning means 40, the pasting means 60 and the cutting means 70 are moved back to the retracted position by the air cylinder 24 of the base 20, and then each part is stopped. It will be in a standby state.

  In the standby state, the operator removes the electric wire portion W1 and the corrugated tube C from the head portion 3 and removes the connector W2 from the connector holding portion 11 and takes out the wire harness W. Thereafter, the operator operates the switch of the sub operation unit 5C to transmit the second winding operation completion signal to the control unit main body 5A, and the control unit main body 5A that has received this signal receives the linear signal of the main body drive unit 4 After the head unit 3 is returned to the initial position by the motor, each unit is stopped, the process is terminated, and the standby state is set. Thus, the second winding operation by the tape winding apparatus 1 is completed.

  According to the tape winding apparatus 1 described above, the tape T is wound around the electric wire portion W1 of the wire harness W by the first winding operation and the exterior member attaching operation, and the corrugated tube C is attached to the outside of the electric wire portion W1. By winding the tape T around the outer side of the corrugated tube C by the double winding operation, the winding of the tape T and the attachment of the corrugated tube C can be executed semi-automatically. Thus, by mechanizing the work conventionally performed manually by the operator, the winding work of the tape T and the attaching work of the corrugated tube C can be made efficient, and the productivity at the wire harness manufacturing site can be improved. Can be improved.

  Moreover, compared with the case where the corrugated tube C is attached to the outer side of the electric wire part W1, after winding the tape T around the electric wire part W1 by performing simultaneously the 1st winding operation | movement and the exterior member attachment operation | movement. The working time required can be greatly shortened, and the working efficiency can be dramatically improved.

  Further, in the second winding operation, a winding operation for winding the tape T around the outside of the corrugated tube C and an unwinding operation for forming a non-winding portion having a predetermined length without winding the tape T are alternately performed.
