JP-A-9-106876 (FIG. 1) Japanese Patent Laid-Open No. 9-223421 (FIGS. 2 to 3) JP 2004-119444 A (FIG. 1) JP 2012-205484 A (FIGS. 1-2) JP-A-7-57566 (FIGS. 1 to 2)

  However, in each of the conventional configurations described above, a sub-wire harness having components such as connectors on the terminal side of each electric wire portion (main line portion or branch line portion) is automatically and efficiently provided on the wiring board. I was unable to route it.

  In view of the above points, the present invention automatically and efficiently routes a sub-wire harness having a component such as a connector on the terminal side of each electric wire portion (main line portion or branch line portion) on a wiring board. An object of the present invention is to provide a harness routing device and a harness routing method.

In order to achieve the above object, a harness routing device according to claim 1 of the present invention is an array in which a plurality of components provided on each terminal side of a sub-wire harness or a plurality of component receivers receiving the components are arranged in parallel. A base, a gripping arm that grips the component or the component receiver, and the gripping arm can be moved in the vertical, horizontal, and height directions on the wiring board, and the electric wires that follow the component of the sub-wire harness are Moving means for moving the gripping arm to the component support part or the component support part of the wiring board in the direction of wiring along the wiring board, and the arrangement table above the wiring board. A second moving means for moving in the direction from one end side to the other end side of the wiring board along the wiring board and in a direction opposite to the direction , one end of which is fixed to the arrangement table, The other end of the wiring board is arranged so that the end side can be inserted and removed freely at one end side of the wiring board. Drawn by該配column table moving toward it and further comprising a sheet member covering the該配search plate.

  With the above configuration, the parts or parts holders on each terminal side of the sub-wire harness are gripped by the gripping arm, detached from the arrangement table by the moving means, and the wires following the parts of the sub-wire harness (in many cases, a plurality of wires) In the state of being led out from the gripping arm, the gripping arm is moved in the two-dimensional or three-dimensional direction by the moving means along the wiring board. It is routed at the same time. The component or component receiver on the terminal side of the electric wire is supported (held) by the component support portion or receiver support portion of the wiring board. In this way, the plurality of electric wires following the terminal-side component of the sub-wire harness are routed on the routing plate simultaneously by the movement of the gripping arm, so that the wires are efficiently routed in a short time. From the standpoint of positioning, it is preferable that the terminal-side component of the sub-wire harness held by the holding arm is a rigid connector.

  Moreover, in the wiring process of the said electric wire, an arrangement | sequence stand is moved along a wiring board according to the wiring position of the electric wire on a wiring board. For example, after arranging the arrangement table on the front end (one end) side of the wiring board and wiring the electric wire in the first half of the wiring board, move the arrangement table to the middle part in the front-rear direction of the wiring board, In a state where the distance to the rear end (other end) of the wiring board is shortened, the parts on the terminal side of the sub-wire harness or the component holders are held by the holding arm from the arrangement table, and the holding arm is moved by the moving means. Move the wires to the second half of the wiring board. Thereby, the movement time of the holding arm (component on the terminal side of the sub-wire harness or the component holder) from the arrangement table to the required arrangement position of the arrangement board is shortened, and the arrangement efficiency of the electric wire is increased. The arrangement table does not need to move to the rear end (the other end) of the routing board. When the wiring position of the wires changes from the second half to the first half of the wiring board, the arrangement base is moved to the front end side of the wiring board, and the electric wires are routed to the first half side of the wiring board.

Further, as the arrangement table moves from one end side to the other end side of the wiring board, the sheet member is pulled out to cover the wiring board between the arrangement table and one end side of the wiring board. The electric wires led out from the parts set on the arrangement stand are placed along the surface of the sheet member, and are separated from the already arranged electric wires on the arrangement board by the sheet member. Thereby, the entanglement etc. of electric wires are prevented.

Harness device according to claim 2 is the harness system according to claim 1 Symbol mounting, wire scraper member is disposed in said sequence table, the electric wire scraper device is in the gripping arm or other gripping arm The electric wire gripped and moved by the moving means is moved toward a target routing route.

  With the above configuration, for example, the gripper component or the component holder is gripped by one gripping arm, moved from the arrangement table by the moving means, the electric wire is routed on the routing board, and the other gripping arm similarly The electric wire scraping tool on the arrangement table is grasped and moved by moving means (which may be common or independent), and the electric wire on the wiring board is moved toward the target wiring path. As the wire scraper on the array base moves along the wiring board together with the array base, the movement of the wire scraper from the array base to the wiring board is the same as in the sub-wire harness component or the component holder. The distance and the travel time are shortened, and the wiring efficiency (the correction of the position of the electric wire is also a part of the wiring) is increased.

  Moreover, in the wiring process of the said electric wire, an arrangement | sequence stand is moved along a wiring board according to the wiring position of the electric wire on a wiring board. For example, after arranging the arrangement table on the front end (one end) side of the wiring board and wiring the electric wire in the first half of the wiring board, move the arrangement table to the middle part in the front-rear direction of the wiring board, In a state where the distance to the rear end (other end) of the wiring board is shortened, the parts on the terminal side of the sub-wire harness or the component holders are held by the holding arm from the arrangement table, and the holding arm is moved by the moving means. Move the wires to the second half of the wiring board. Thereby, the movement time of the holding arm (component on the terminal side of the sub-wire harness or the component holder) from the arrangement table to the required arrangement position of the arrangement board is shortened, and the arrangement efficiency of the electric wire is increased. The arrangement table does not need to move to the rear end (the other end) of the routing board. When the wiring position of the wires changes from the second half to the first half of the wiring board, the arrangement base is moved to the front end side of the wiring board, and the electric wires are routed to the first half side of the wiring board.

According to the invention of claim 1 Symbol placement, be automatically efficiently routed sub wire harnesses each having a component such as a connector or the like on the terminal side of the electric wire portion (trunk and branch line) on the wiring board it can.

Furthermore, to prevent interference between the arranging stand side of the wire and the wiring board side of the electric wires in sheet over preparative member, it is possible to perform the routing of the wire smoothly.

Moreover, according to the invention of Claim 2, the movement of the electric wire scraper from an arrangement | sequence stand to a wiring board can be efficiently performed in a short time.

A laterally long plate-like wiring receiver 14 inclined rearward is provided at the lower rear portion of the array table 4.

  The wiring receiver 14 is used when the electric wire 11 of the connector 10 is led backward from the connector holder 5 and hung downward in the gap between the rear end of the arrangement table 4 and the front end of the routing board 3. In this case, for example, the arrangement table 4 is sent to the harness routing device 1 by a guide rail (not shown) extending in the left-right direction after completing the terminal insertion in the previous process. In this example (FIG. 4), an example in which the electric wire 11 is led out from the connector 10 is described.

  As shown in FIGS. 1 to 3, on the upper part of the frame 2, there are a horizontal X-axis rail (moving means) 15 extending in the left-right (lateral) direction, and a slide engaging portion (moving portion) 19 of the X-axis rail 15.

The connector holder 5 is made of metal or synthetic resin and has a connector receiving portion 26 and an arm gripping portion 27 at the front and rear. The connector receiving portion 26 includes a connector housing space 26a having openings 26a 'on the front side and the upper side, and a lock means (not shown) that locks the connector 10 in the connector housing space 26a. The arm gripping portion 27 has a gripping wall 27a perpendicular to the rear side. The form of the connector holder 5 is not limited to this, and various forms can be set as appropriate.

  A pair of front and rear chucks 23a of the gripping arm 23 grips the arm gripping portion 27a in a state where the connector 10 is housed and locked in the connector receiving portion 5, and grips by the compression operation of the rod of the vertical air cylinder 18 (FIG. 1). The arm 23 lifts and removes the connector receiver 5 from the arrangement table 4 of FIGS.

  As another example of the connector receiver (5), the connector 10 shown in FIG. 5 is arranged on the connector receiver (5) in the reverse direction so that the electric wire 11 of the connector 10 is led out to the rear side, that is, the holding arm 23 side (arrangement). It is also possible to arrange the connector holder 5 on the table 4 in the reverse direction. In this case, immediately after the connector holder (5) is lifted from the arrangement table 4 (FIG. 2), it is inverted 180 ° in the front-rear direction by the rotation drive unit 22 (FIG. 1).

  FIG. 6 shows a state in which the grip arm 23 grips the electric wire scraper 28 instead of the connector receiver 5 (FIG. 5). For example, one or two electric wire scraping tools 28 are arranged on the arrangement table 4 (FIG. 1) along with the connector receiver 5. The electric wire scraping tool 28 is a state in which the upper vertical plate portion 28c is gripped by the pair of chucks 23a of the gripping arm 23 by the driving means of the rails 15 to 17 of each axis. While moving along the upper surface 3a, the electric wire 11 (FIG. 4) on the wiring board 3 is scraped toward the target wiring position.

  The tip (lower end) 28a 'of the electric wire scraping tool 28 comes into contact with the upper surface 3a of the wiring board 3 (FIG. 1) without any gap. For example, in a state where the lower half portion 28a of the electric wire scraping tool 28 slides downward with its own weight or the like with respect to the upper half portion 28b, the tip (lower end surface) 28a ′ of the lower half portion 28a is the routing board 3. It is made to contact (contact) the upper surface 3a.

  It is also possible to bring the lower half portion 28a of the electric wire scraping tool 28 into contact with the wiring board 3 in a state where it is biased downward by a spring member (not shown) in addition to its own weight with respect to the upper half portion 28b. It is preferable that a hole is provided in the lower end surface 28a 'of the lower half portion 28a of the electric wire scraping tool 28, and the hole is engaged with a pin projecting from the upper surface of the arrangement table 4 (FIG. 1) for positioning. The electric wire scraping tool 28 is disposed, for example, on the end side of the arrangement table 4.

  FIG. 7 shows a part of the routing board 3 (left half side). On the upper surface (front surface) 3a of the routing board 3, each connector holder 5 is arranged by being moved from the arrangement table 4 (FIG. 2) by the gripping arm 23 (FIG. 1). A bottom plate 29 (FIG. 1) is disposed on the lower side (back side) of the routing plate 3, and a plurality of horizontal air cylinders 30 are disposed at appropriate positions, and are perpendicular to the distal end side of the rod 30 a of each air cylinder 30. The wire scraping pins 31 are arranged upward, and the routing board 3 is provided with long holes 32 (FIG. 9) for protruding the wire scraping pins 31 upward. The longitudinal direction of the long hole 32 coincides with the advance / retreat direction of the electric wire scraping pin 31.

  In addition, the routing plate 3 is engaged with a pin 8 (FIG. 4) or a hole on the bottom surface of the connector receiving member 5 in order to transfer and hold the connector receiving members 5 with the gripping arms 23 (FIG. 1). A hole or pin (receiver support part) 33 is provided. It is preferable in terms of detents that two holes or pins serving as the support support portions 33 are arranged corresponding to the two cylindrical pins 8 (FIG. 4) or holes of the connector support 5. . The same applies to the arrangement table 4. The wiring board 3 can be replaced according to the part number of the sub-wire harness.

  For example, as shown in FIG. 8 (a), a vertical air cylinder 34 is fixed to the tip of a rod 30a of a horizontal air cylinder 30 via a connecting portion 30c, and the rod that can be advanced and retracted by the vertical air cylinder 34 attracts the electric wire. Also serves as pin 31. The cylindrical portion 30b of the horizontal air cylinder 30 is fixed to a bottom plate 29 located below the routing plate 3 with front and rear brackets 35.

  The wire scraping pin 31 protrudes upward through the long hole 32 of the wiring board 3, moves along the long hole 32 by the compression operation of the horizontal air cylinder 30, and is wired by the compression operation of the vertical cylinder 34. Retract below the upper surface 3 a of the plate 3. It is also possible to invert the horizontal air cylinder 30 by 180 ° in the longitudinal direction (to obtain the position of the electric wire scraping pin 31 in FIG. 8A by the compression operation).

  Alternatively, as shown in FIG. 8B, the wire scraping pin 31 is fixed upward to the tip of the rod 30a of the horizontal air cylinder 30 via the connecting portion 30c, and the cylindrical portion 30b of the air cylinder 30 is attached to the front and rear brackets 35. The substrate portion 36 is supported by a rod 37a of a vertical air cylinder 37 so as to be movable up and down, and the vertical air cylinder 37 is fixed to the bottom plate 29 by a lower bracket 38. The operation is the same as in FIG. The lifting structure shown in FIG. 8A is preferable in terms of simplification and compactness.

  Below, one Embodiment of the harness routing method using the effect | action of the said harness routing apparatus 1, ie, the harness routing apparatus 1, is described.

  As shown in FIG. 1, first, an operator or a terminal insertion device (not shown) in the previous process attaches connectors 10 (FIG. 5) with electric wires 11 to the respective connector holders 5 on the arrangement table 4, and arranges the arrangement table 4. An electric wire scraper 28 (FIG. 6) is disposed on the scraper support portion. The electric wire scraping tool 28 can also be disposed on the connector support supporting portion of the arrangement table 4. The arrangement order of each connector (the type is different for each connector) 10 (FIG. 5) to the array table 4 is random, but in which position of the array table 4 the connector 10 of which part number is arranged is set in advance. (Programmed) and recorded in a control device (not shown).

  The X-axis rail 15 (FIG. 1), for example, one Y-axis rail 16 (FIG. 2) and Y′-axis rail 17 (FIG. 3) are integrated with one vertical air cylinder 18 (FIG. 1) in the Z-axis direction. One gripping arm 23 moves above the array table 4, and the grip arm 23 descends by the extension operation of the air cylinder 18 to grip the first connector holder 5 on the array table 4. The connector holder 5 is detached from the array table 4 while being raised by the compression operation 18. “First” does not mean from the end of the arrangement table 4 but means the first selection order set in advance.

  Next, as shown in FIG. 9 as an example, the first connector holder 5 is integrated with the grip arm 23 from the state in which the electric wire 11 of the connector 10 in the first connector holder 5 is led forward. Along the upper surface 3a of the cord board 3 (with a gap between the upper surface 3a) and the rails 15 to 17 of each axis in the XY direction (two-dimensional direction), that is, rearward or left-right direction (after moving backward, forward You can also move to). At this time, the first connector receiver 5 is lowered so as to approach the upper surface 3 a of the wiring board 3 integrally with the gripping arm 23 by the extending operation of the air cylinder 18 (FIG. 1).

  By these operations, the electric wire 11 led out from the connector 10 in the first connector holder 5 (following the connector 10) is moved along the vicinity of the first target wiring path L (FIG. 9) of the wiring board 3. To route. At that time, the electric wire scraping pin 31 in the first target routing route L is moved upward in the state of protruding upward from the routing plate 3 in FIGS. 7 and 9 and moved away from the target routing route L. (A pair of opposing electric wire scraping pins 31 is left open). The electric wire 11 of the connector 10 is routed on the wiring board 3 through between the electric wire scraping pin 31 and the target routing route L.

For example 11 (derived wire from the connector 10) left of the connector 5 ₁ of the wire of Figure 7, but is laid out from the target routing path as indicated by a dotted line 11 _1, away than its laid position A wire scraping pin 31 ₁ indicated by a dotted line is arranged at a position, that is, a position where the rod 30a of the horizontal air cylinder 30 ₁ is extended, and passes through the inner side of the wire scraping pin 31 _{1 in} the restoring direction (wire scraping). The electric wire 11 ₁ is routed through the range of the advance / retreat stroke of the pin 31 ₁ . Wiring of the electric wire 11 ₁ is performed by moving by the gripping arm 23 (FIG. 9) only the connector receiving tool 5 ₁ together with the connector 10.

The wires 11 ₁ after wiring, by compressing the horizontal air cylinder 30 ₁ of the rod 30a, by moving the pin 31 ₁ raked wire rod 30a integral restoration direction, raked pin 31 ₁ wire 11 ₁ is moved to the target routing route (position indicated by reference numeral 11 in FIG. 7). Immediately after the wiring of the electric wire 11, the connector holder 5 is further lowered by the extending operation of the vertical air cylinder 18 (FIG. 1) together with the gripping arm 23 (FIG. 9), and is delivered to and held by the wiring board 3. That is, the pin 33 (FIG. 7) or the hole on the bottom surface of the connector receiver 5 is engaged with the hole or pin (receiver support portion) of the wiring board 3 to be positioned and supported.

As indicated at 11 ₂ in FIG. 7, the length of the flexible range of the horizontal air cylinder 30 ₁ of the rod 30a (elongated hole 32 ranging That wiring board 3 of the reciprocating stroke of the wire scraper pins 31 ₁ (FIG. 9) in a case where the range) than there wires 11 ₂ outwardly of possibly be routed (if it is known in advance), according to a preset program, the electric wire scraper pins 31 ₁ wiring in a state retracted to the lower side of the plate 3 (it may be previously retracted, may be retracted after the wire routing), to correct the position of the wire 11 ₂ using a wire scraper device 28 in FIG. 6. For example, the position of the wire 11 ₂ off is interior than the pin 31 scraped wires shown by the solid line in compressed side of the air cylinder 30 ₁ (front side in FIG. 7), the scraping wire of the extended side jogger without retracted pin 31 ₁ on the lower side of the Haisakuban 3, we are possible to modify the position of the wire 11 ₂ to the expansion and contraction range of the air cylinder 30 ₁ of the rod 30a in the wire scraper tool 28.

That is, the other gripping arm 23 of FIG. 1 picks up the wire scraper 28 of FIG. 6 from the array 4 (FIG. 1), and the wire scraper 28 (FIG. ) is, range of the air cylinder 30 ₁ of the wire 11 ₂ deviated outward along the upper surface 3a of Haisakudai 3 as indicated by an arrow P in FIG. 7 flexible range of the rod 30a (the forward and backward strokes of the wire scraper pins 31 Push it back in (range). Thereafter, wire scraper pins 31 ₁ protrudes over-installing plate 3 perpendicular operation of the air cylinder 34, 37 in FIG. 8, the pin 31 ₁ scraped wire in compression operation of the horizontal air cylinder 30 (FIG. 7 ) to the target routing path is moved by pushing the wire 11 _2.

The first and second air cylinders 30 ₁ and 30 ₂ from the left in the example of FIG. 7 correct (correct) the positions of the wires 11 ₁ to _{3 by} the compression operation of the rod 30a, but the other air cylinders 30 are rods The position of the electric wire 11 is corrected by the extending operation of 30a (the electric wire 11 is moved to the target routing route). Whether the position of the electric wire 11 is corrected by the compression operation of the rod 30a or the extension operation depends on the relationship of the air cylinder arrangement space on the back side of the wiring board 3 and the like.

Examples of the left end of the first connector receptacle 5 ₁ of the connector wires 11 ₁ of the installation which are derived from 10 of Figure 7, the rod 30a of the third air cylinder 30 ₃ from the left in FIG. 7, the rod 30a of compressing the rod 30a of the air cylinder 30 ₄ having a wire scraper pins 31 ₄ adjacent to the wire scraper pins _313, both wire scraper pin 31 _3, 31 both wires raking in a state _{of 4} to open This is done by inserting the wire 11 ₁ between the pins 31 ₃ and 31 ₄ .

In this case, installation path of the wire 11 ₁ both wire scraper pin 31 _3, 31 ₄ of the retractable may be within the range, if the outside than the range, the aforementioned wire scraper device 28 (FIG. 6 ) in both wire scraper pin 31 _3, 31 after moving the electric wire 11 ₁ in reciprocating range of _4, by moving the closing direction the pin 31 _3, 31 ₄ scraped both wires, the wires 11 ₁ target The position is corrected (corrected) along the route. The wire scraping tool 28 can also be gripped and moved by the same gripping arm 23 (the gripping arm dedicated for routing) as the wire 11 is routed. In this case, the total number of the grip arms 23 may be one. The total number of the gripping arms 23 can be three or more.

  Further, after the grip arm 23 (FIG. 1) lifts the connector holder 5 from the arrangement table 4, for example, according to the wiring direction of the electric wire 11 of the connector 10, the rotational drive unit 22 (FIG. 1) on the upper side of the grip arm 23. ) To rotate the gripping arm 23 at an appropriate angle in the horizontal direction, thereby bending the electric wire 11 of the connector 10 in a required direction above the wiring board 3, and extending the electric wire of the connector 10 along the target wiring path. It is also possible to correct the direction of 11. In this orientation, the connector receptacle 5 is transferred to the receptacle support portion 39 (FIG. 9) of the wiring board 3 (the pin 8 on the bottom surface of the connector receptacle is engaged with the hole (receiver support portion) 39 of the wiring board 3. Alternatively, the orientation of the connector receptacle 5 (orientation of the connector 10) can be changed by the rotation drive portion 22 (FIG. 1) above the receptacle support portion 39 of the wiring board 3.

  In this way, the second, third... Connector holder 5 is gripped by the gripping arm 23 and moved in the XY directions by the moving means 15 to 17, thereby arranging the wires 11 led out from the connectors 10. The search is done. As long as the number of wires 11 on the wiring board 3 is small, the gripping arm 23 allows the wire 11 of the connector 10 in the connector holder 5 to pass through the space above the pair of wire scraping pins 31, for example. However, as the number of wires 11 on the wiring board 3 increases, the particularly short wires 11 are higher than the wire scraping pins 31 and cannot be lifted by the gripping arm 23. Therefore, the gripping arm 23 is moved between the pair of electric wire scraping pins 31 as shown in FIG.

  As for the sub-wire harness arranged on the array base 4 in FIG. 1, there are few U-shaped ones having the connector 10 at one end and the other end of the electric wire 11, and as shown in FIG. For example, the connector 10 of one terminal 11a of the first branch line 11B is connected to each connector 10 of the other terminal 11a of the second and third branch lines 11B. There are many subwire harnesses 40 of such a form. For this reason, it is necessary to route the cable between the pair of electric wire scraping pins 31 (FIG. 9) as described above.

  Further, as shown in FIG. 7, for example, the fourth connector holder 5 is grasped as the wiring 11 is routed on the wiring board 3 or in the middle of the wiring 11 wiring on the wiring board 3. When the arm 23 is gripped and moved in the XY direction, the electric wire 11 led out from the connector 10 of the fourth connector receiver 5 is routed in, for example, any one of the first to third connectors or the fifth connector receiver 5. There is a concern that the wire 11 already laid on the plate 3 may get entangled, and the fourth connector holder 5 is held by the holding arm 23 according to a preset program, and the wire 11 may be entangled. The XYZ moving means 15 to 18 are used to move to the position of the array table 5 where there is no position.

  In this state, the fifth connector holder 5 is held by the holding arm 23, and the electric wire 11 of the connector 10 in the fifth connector holder 5 is arranged along the routing board 3 by the moving means 15 to 18. After that, the fourth connector holder 5 is again picked up (detached) from the arrangement table 4 by the gripping arm 23, and each of the moving means 15 to 18 moves the connector 10 in the fourth connector holder 5. The electric wire 11 is routed along the routing board 3.

  Each connector receptacle 5 is delivered and held on the routing plate 3 every time the electric wire 11 of the connector 10 in the connector receptacle 5 is routed by the grip arm 23 (the pin 8 or the hole on the bottom surface of the connector receptacle 5). Need to be engaged with the hole 39 or the pin of the routing board 3).

  Below, the movement of the arrangement | sequence table 4 in the front-back direction and the effect | action of the roll curtain 12 (FIG. 4) are demonstrated using FIGS. 1-10 and FIGS.

  1 to 4, the arrangement table 4 is a middle portion in the front-rear direction from the front end side to the rear end side of the routing plate 3 by driving means (screw shaft, nut portion, and motor) along a pair of left and right guide rails 6. It can move to (desired position).

  For example, when the connector holder 5 is moved from the arrangement base 4 to the rear half side of the arrangement board 3 by the gripping arm 23, the arrangement base 4 is moved to the front end side of the arrangement board 3 as shown in FIGS. 2 and 11 to 12. From the upper side of the wiring board 3 to the middle in the front-rear direction of the wiring board 3.

  As a result, the distance in the front-rear direction from the arrangement table 4 to the receiving support section (the hole 39 or the pin engaging the pin 33 or the hole of the connector receiving apparatus 5) on the rear half side of the wiring board 3 is shortened. The time for carrying the connector receiver 5 from the base 4 to the receiver support 39 on the rear half side by the grip arm 23 is shortened. Moreover, when the short electric wire 11 of the sub-wire harness 40 (FIG. 10) is routed to the second half side of the wiring board 3, the short electric wire 11 may not reach the second half side of the wiring board 3. Also in that case, after moving the arrangement | sequence stand 4 back, the short electric wire 11 is routed.

  The arrangement table 4 that has moved rearward is located above the connector receptacle 5 that is arranged on the wiring board 3. When moving the arrangement table 4 backward, the wire scraping pin 31 protruding above the wiring board 3 protrudes higher than the connector receptacle 5, so that the wire scraping pin 31 is vertical as necessary. The air cylinders 34 and 37 (FIG. 8) are compressed to retract to the lower side of the wiring board 3 or lower than the arrangement table 4 to prevent interference with the arrangement table 4. Alternatively, the electric wire scraping pins 31 shorter than the height of the lower end of the arrangement table 4 are used to pass the arrangement table 4 without retracting the electric wire scraping pins 31.

  When the moving position of the connector holder 5 is changed from the second half side to the first half side of the wiring board 3, the arrangement table 4 is appropriately advanced. As described above, the movement of the array table 4 in the front-rear direction is appropriately performed (one or more times) in the process of routing one sub-wire harness 40. The sub-wire harness 40 (FIG. 10) includes at least a plurality of electric wires 11 and connectors 10 provided at the terminals of the electric wire portions (electric wire groups) 11A and 11B. A plurality (at least two) of electric wires 11 are led out from the connector 10.

  Since the front end (rear end) of the sheet member (film part) 12a of the roll curtain 12 shown in FIGS. 4, 11, and 12 is fixed to the array table 4, the roll curtain 12 is cylindrical when the array table 4 is retracted. The arrangement board 4 is moved forward and backward together with the arrangement table 4 so that the arrangement table 4 is drawn by the spring force of a spring member (not shown) when the arrangement table 4 moves forward.

  As shown in FIGS. 11 and 12, when the arrangement table 4 is retracted, the sheet member 12 a that is pulled out rearward covers the wiring board 3, and has already been placed on the front half of the wiring board 3. The tool 5 and the already wired electric wire 11 are isolated and protected from the outside. In this state, when the gripping arm 23 picks up the next connector receiver 5 from the arrangement table 3 and moves it backward, the electric wire 11 led forward from the connector 10 of the connector receiver 5 extends along the upper surface of the sheet member 12a. Thus, the interference with the already arranged connector receptacle 5 and the already wired electric wire 11 is prevented. In the case where the electric wire 11 of the connector 10 is led out rearward from the connector holder 5 instead of forward, the electric wire 11 is U-turned forward near the rear side of the connector 10 and disposed on the sheet member 12a.

  The electric wire 11 of the connector 10 on the arrangement table 4 and the electric wire 11 on the wiring board 3 are separated by the sheet member 12a and prevented from being entangled, so that the smooth and reliable wiring of the electric wire 11 to the wiring board 3 is performed. Is possible. It goes without saying that the wires 11 are routed by moving the connector holder 5 with the gripping arm 23 and routing the wires 11 of the connector 10 in the connector holder 5 on the routing plate 3.

  In the embodiment of FIGS. 1 to 10, in the description of the operation of the two gripping arms 23 in FIGS. 1 to 3, the connector holder 5 is gripped by one gripping arm 23, and the other gripping arm 23 is gripped. Although the example which grasped the electric wire scraping tool 28 (FIG. 6) was demonstrated, each connector receptacle 5 is each hold | gripped with the two holding arms 23, and it moves on the wiring board 3 by each moving means 15-18. It is also possible to route the electric wire 11 of each connector 10 and carry it to each receiving tool support 39 (FIG. 9) on the wiring board 3.

  In the example of FIGS. 1 to 3, a pair of Y-axis rails 16 (FIG. 1) that support two gripping arms 23 are connected to the X-axis rail 15 by a single slide engagement portion 19. Since the shaft rail 16 can move independently in the Y (front / rear) direction together with each gripping arm 23 and moves integrally in the X (left / right) direction, the connector holder 5 is gripped by one gripping arm 23 and the other The electric wire scraping tool 28 is held by the holding arm 23.

  On the other hand, a pair of Y-axis rails 16 (FIG. 1) that support the two gripping arms 23 are connected to the X-axis rails 15 by independent slide engaging portions 19, respectively. The wiring 11 of the connector 10 on the left half side of the cable board 3 is routed by the left holding arm 23, and at the same time or separately, the cable 11 of the connector 10 on the right half side of the cable board 3 is wired. Can be performed by the right gripping arm 23.

  In this case, for example, if any one of the holding arms 23 delivers the connector holder 5 onto the wiring board 3 as necessary, the electric wire scraping tool 28 is taken up from the arrangement table 4 and the wiring board 3 is placed on the wiring board 3. The already-wired electric wire 11 is moved so as to approach the target wiring route. Thereafter, the electric wire scraping pin 31 of the wiring board 3 moves the electric wire 11 along the target wiring path. The used wire scraping tool 28 is returned from the grip arm 23 to a predetermined position on the arrangement table 4.

  The wiring of all the wires 11 of the connectors 10 is completed on the wiring board 3, and the sub-wire harness 40 is developed on the wiring board 3 in a predetermined shape (for example, an assembly shape to the vehicle). There are cases where plural types (for example, two types) of sub-wire harnesses 40 are combined on the wiring board 3 (both sub-wire harnesses are terminal-connected). Then, for example, on the wiring board or in a later process, an exterior component (harness component) such as a corrugated tube, a locking clip, a protector, a waterproof grommet, or the like is attached to the sub-wire harness 40, and the wire harness (assembled wire) is predetermined. Complete with specifications.

  In the above embodiment, the connector receiver 5 is gripped by the grip arm 23. For example, instead of the connector receiver 5, the connector itself (connector housing) 10 is directly gripped by the grip arm 23, and the wiring board 3 It is also possible to route the electric wire 11 of the connector 10 on the wiring board 3 while carrying it. In this case, the grip arm 23 may have a flexible member such as rubber on the grip surface so that the connector housing is not damaged.

  Each connector holder (with the shape obtained by removing the gripping portion 27 from the connector receiver 5) is arranged on the array base 4, and the connector 10 with the electric wire 11 in each connector holder is gripped by the grip arm 23. Remove from the connector holder. A connector support portion (support member) (not shown) in a form corresponding to each connector 10 is set in advance on the wiring board 3.

  Further, instead of gripping the connector 10 with the grip arm 23, an exterior component such as a corrugated tube or the like (preferably a hard one) mounted on the terminal side of the plurality of wires of the sub-wire harness is placed on the arrangement table 4. It is also possible to route the lead-out wire 11 from the exterior component onto the wiring board 3 while being gripped by the gripping arm 23 from the component receiver (not shown) and being carried on the wiring board 3. In this case, the wiring board 3 is previously provided with a component support portion (support member) that supports the exterior component. The exterior component is provided adjacent to the connector 10 of the sub-wire harness 40.

  Further, instead of directly gripping the exterior parts with the gripping arm 23, the parts receiver with the exterior parts set is gripped and picked up by the gripping arm 23 from the arrangement table 4 and carried on the wiring board 3 while receiving the parts. It is also possible to route the lead-out wire 11 from the exterior component inside the tool on the routing board 3. In this case, similarly to the connector receiver 5, the routing board 3 is provided with a receiver support portion such as a hole 39 or a pin that supports a pin or a hole at the bottom of the component receiver.

  Moreover, in the said embodiment, the position of the electric wire 11 on the routing board 3 was corrected using the electric wire scraping pin 31 and the electric wire scraping tool 28 (the electric wire 11 is moved toward the target routing route L). However, without using the wire scraping pin 31, the wire scraping tool 28 is gripped by any one of the pair of gripping arms 23 and is already routed on the wiring board 3. It is also possible to correct the position by moving the completed electric wire 11 toward the wiring target path L on the wiring board 3 with the electric wire scraping tool 28.

  In addition, in the state where the wire positioning pin (not shown) that can be moved (lifted / moved only in the vertical direction) is protruded on the wiring board 3 instead of the wire scraping pin 31 that can move in the horizontal direction. It is also possible to move the electric wire 11 on the wiring board 3 toward the direction of the electric wire positioning pin, that is, toward the target routing route L by the electric wire scraping tool 28 held by the arm 23.

  The harness routing device and the harness routing method of the present invention automatically and efficiently route a sub-wire harness having a harness component such as a connector on the terminal side of each electric wire (trunk line or branch line) on the routing board. Can be used to
