The wire harness assembling auxiliary tool 30 includes an auxiliary tool base 32 and an assembling auxiliary part 36. The auxiliary tool base 32 is a substantially columnar member, and is configured to be able to stand on the assembly table 20. Here, the bolt 33 suspended from the lower end of the auxiliary tool base 32 is passed through the insertion hole 22h of the drawing plate 22, and a nut (not shown) is screwed and fastened to the bolt 33, whereby the auxiliary tool base 32 is moved. It is erected on the assembly table 20. However, the auxiliary tool base 32 may be erected and fixed to the assembly table 20 by various fitting structures or the like. A recess 34 that opens upward is formed at the upper end of the auxiliary tool base 32. The recess 34 is surrounded on three sides by a pair of wall portions 34a and a receiving wall portion 34b that closes one side opening between the pair of wall portions 34a. Further, a substantially U-shaped groove 34c is formed at a position facing the receiving wall 34b in the recess 34. And the said assembly assistance part 36 is supported by the said recessed part 34 so that an attitude | position change is possible (refer FIG. 2).

  The assembly assisting part 36 is a part for acting on the wire harness WH when the wire harness WH is assembled to assist the assembling work. The assembly assisting part 36 has an upright posture and a tilted posture with respect to the assisting tool base 32. It is supported so that the posture can be changed between. More specifically, the lower end portion of the assembly assisting portion 36 is disposed in the recess 34, and the pin-shaped shaft member 35 is inserted into the pair of wall portions 34 a and the lower end portions of the assembly assisting portion 36. Yes. Then, the assembly assisting portion 36 has an upright posture (see FIG. 2) with the side surface in contact with the receiving wall portion 34b, and an inclined posture (with the side surface disposed and in contact with the substantially U-shaped groove 34c). (See FIG. 3). In addition, a positioning protrusion by a ball blanker ball or the like is provided on the auxiliary tool base 32, and when the assembly assisting part 36 is changed to the upright posture, the positioning protrusion is fitted into a recess provided in the assembly assisting part 36. By doing so, it is preferable that the assembly assisting part 36 be held in an upright posture.

  At the tip of the assembly assisting portion 36 as described above, necessary members are attached for the convenience of work when assembling the wire harness WH, such as a terminal holder, a clamp holder, and a work position indicator. As a terminal holder, the structure which can hold | maintain the terminal part of the wire harness WH, for example, hold | maintains the electric wire part of the wire harness WH formed in the substantially U shape or the substantially fork blade shape, and arrange | positioned between each rod shape. What has a recessed part which can hold | maintain the connector attached to the terminal part of wire harness WH, or the like etc. is used.

And the posture is changed between the tilted posture (see FIG. 3).

  FIG. 4 is an explanatory diagram showing the overall configuration of the upright tilt switching device of the wire harness assembling auxiliary tool, and FIGS. 5 to 8 are explanatory diagrams showing the operation of the upright tilt switching device. In FIG. 4, the wire harness assembling auxiliary tool 30 is illustrated in a simplified manner, and in particular, the upper end portion thereof is omitted.

  The upright tilt switching device 40 of the wire harness assembling auxiliary tool 30 is configured to change the posture of the assembling auxiliary portion 36 of the wire harness assembling auxiliary tool 30, and the linear member 42A for upright and the posture changing drive for upright. 50 A of mechanism parts, the linear member 42B for tilting, and the attitude change drive mechanism part 50B for tilting are provided.

  The upright linear member 42A and the upright posture changing drive mechanism 50A are components for changing the posture of the assembly assisting portion 36 from the tilted posture to the upright posture.

  That is, the upright linear member 42A is constituted by a linear member that can be loosely deformed, such as a resin wire, a metal wire, or a string. One end portion of the upright linear member 42A is connected to one end portion of the posture change transmission member 38 (more specifically, the end portion opposite to the direction in which the assembly assisting portion 36 is tilted), thereby When the upright linear member 42A is pulled, the assembly assisting portion 36 changes the posture from the tilted posture to the upright posture.

  The upright posture changing drive mechanism 50A changes the posture of the assembly assisting portion 36 from the tilted posture to the upright posture by pulling the upright linear member 42A, and after the posture of the assembly auxiliary portion 36 is changed, The member 42A is configured to be loosened.

  More specifically, the upright posture change drive mechanism unit 50A includes a pneumatic cylinder 52A as a fluid pressure cylinder and a working fluid switching supply unit 60A that supplies air as a working fluid to the pneumatic cylinder 52A. .

  The pneumatic cylinder 52A has a rod portion 54A that can be driven back and forth with respect to the main body portion 53A. Here, the rod portion 54A is constantly urged in the advancing direction by an urging member such as a coil spring built in the pneumatic cylinder 52A. The rod portion 54A is driven to retract by supplying air to the main body portion 53A, and the rod portion 54A is driven to advance by exhausting air in the main body portion 53A. The other end portion of the upright linear member 42A is connected to the distal end portion of the rod portion 54A via a linear member connecting member 56A. The length of the upright linear member 42A is such that the upright linear member 42A is pulled or slackened when the assembly assisting portion 36 is in a tilted posture and the rod portion 54A is in the advanced state. Thus, when the assembly assisting portion 36 is in the upright posture and the rod portion 54A is in the retracted state, the upright linear member 42A is set to a tensioned state. Then, when the assembly assisting portion 36 is in the tilted posture, the rod portion 54A is driven to retract and the upright linear member 42A is pulled to change the posture of the assembly assisting portion 36 to the upright posture. From this state, the rod portion 54A When the upright linear member 42A is slackened, the posture restrained state by the upright linear member 42A is released, and the assembly assisting portion 36 can be changed in posture from the upright posture to the tilted posture.

  The upright linear member 42A is guided to the linear member connecting member 56A provided at the tip of the pneumatic cylinder 52A through a hole formed in the graphic plate 22 and guided below the graphic plate 22. It is. Although FIG. 4 shows an example in which the pneumatic cylinder 52A is disposed directly below the wire harness assembling auxiliary tool 30, this is not always necessary. A linear member connecting member provided at the front end of a pneumatic cylinder 52A, which is guided while bending the linear member 42A for upright through a guide roller or the like as appropriate. You may make it connect with 56A.

  When the working fluid switching supply unit 60A receives the posture change instruction via the upright side start switch 62A that is an instruction receiving unit, the working fluid switching supply unit 60A drives the rod unit 54A to retract so that the linear member 42A for erecting is pulled, and also retracts the rod unit 54A. After driving, air is supplied to the pneumatic cylinder 52A so as to drive the rod portion 54A forward so as to loosen the linear member 42A for standing.

  More specifically, the working fluid switching supply unit 60A includes an upright side activation switch 62A, a timer built-in relay 63A, and an electromagnetic valve 64A.

  The upright side start switch 62A is configured by a push switch or the like, and is configured to be able to accept an upright posture change instruction from an operator. The upright posture change instruction received by the upright side start switch 62A is given to the timer built-in relay 63A.

  The timer built-in relay 63A is a relay with a built-in timer circuit, and is inserted in a switch on / off circuit between the power source 65 and the electromagnetic valve 64A. When an upright posture change instruction is input from the upright side start switch 62A, an on-voltage is applied to the electromagnetic valve 64A for a predetermined time set in advance. The predetermined time is set to be equal to or longer than the time required for the assembly assisting portion 36 to change the posture between the tilted posture and the upright posture by the retracting drive of the rod portion 54A.

  The solenoid valve 64A is inserted in an air line between the air supply source 66 and the pneumatic cylinder 52A. In a normal state, the solenoid valve 64A is shut off between the air supply source 66 and the pneumatic cylinder 52A. The operating air can be exhausted to the outside, and the air supply source 66 and the pneumatic cylinder 52A are opened during the period when the ON voltage is applied from the power source 65 via the timer built-in relay 63A. Thus, the air from the air supply source 66 is configured to be supplied to the pneumatic cylinder 52A.

  The power source 65 and the air supply source 66 are normally used in common in both the working fluid switching supply units 60A and 60B.

  Then, when an operator or the like gives an instruction to change the posture via the upright side start switch 62A, air is supplied to the pneumatic cylinder 52A for a predetermined time set in advance, and the rod portion 54A is retracted to drive the upright linear member 42A. After a predetermined time has elapsed, air supply to the pneumatic cylinder 52A is shut off and the air inside is exhausted to the outside, and the rod portion 54A is driven forward to cause slack in the upright linear member 42A. It is configured. Thus, by controlling the air supplied to the pneumatic cylinder 52B, the upright linear member 42A can be pulled or slackened.

  The tilting linear member 42B and the tilting posture changing drive mechanism 50B are components for changing the posture of the assembly assisting unit 36 from the upright posture to the tilting posture, and are different due to different posture changing directions. Except for this, the upright linear member 42A and the upright attitude change drive mechanism 50A have the same configuration.

  That is, the tilting linear member 42B is formed of a linear member that can be loosely deformed, like the upright linear member 42A. One end portion of the tilting linear member 42B is connected to the other end portion of the posture change transmission member 38 (more specifically, the end portion on the side in which the assembly assisting portion 36 is tilted). By pulling the wire member 42 </ b> B, the assembly assisting part 36 changes the posture from the upright posture to the tilted posture.

  The tilting posture changing drive mechanism 50B changes the posture of the assembly assisting portion 36 from the upright posture to the tilting posture by pulling the tilting linear member 42B, and after the posture of the assembly assisting portion 36 is changed, the tilting linear shape is changed. The member 42B is configured to be loosened.

  More specifically, the tilting posture changing drive mechanism unit 50B includes a pneumatic cylinder 52B (corresponding to the pneumatic cylinder 52A) and a working fluid switching supply unit 60B (working fluid), like the upright posture changing drive mechanism unit 50A. Corresponding to the switching supply unit 60A).

  Similar to the pneumatic cylinder 52A, the pneumatic cylinder 52B has a rod portion 54B (corresponding to the rod portion 54A) that can be driven back and forth with respect to the main body portion 53B (corresponding to the main body portion 53A). The other end of the tilting linear member 42B is coupled to the tip of the rod portion 54B via a linear member coupling member 56B. The length of the tilting linear member 42B is such that the tilting linear member 42B is pulled or slackened when the assembly assisting portion 36 is in the upright posture and the rod portion 54B is in the advanced state. Thus, when the assembly assisting portion 36 is in the tilting posture and the rod portion 54B is in the retracted state, the tilting linear member 42B is set to be pulled. When the assembly auxiliary portion 36 is in the upright posture, the rod portion 54B is retracted and the linear member 42B for tilting is pulled, and the posture of the assembly auxiliary portion 36 is changed to the tilted posture. From this state, the rod portion 54B When the tilting linear member 42B is slackened by being driven forward, the posture restrained state by the tilting linear member 42B is released, and the assembly assisting portion 36 can be changed in posture from the tilted posture to the upright posture.

  The working fluid switching supply unit 60B includes a tilt side start switch 62B (corresponding to the upright start switch 62A), a timer built-in relay 63B (corresponding to the timer built-in relay 63A), and a solenoid valve 64B (corresponding to the solenoid valve 64A). And have.

  Then, when an operator or the like gives an instruction to change the posture via the tilt side activation switch 62B, air is supplied to the pneumatic cylinder 52B for a predetermined time set in advance, and the rod portion 54B is driven to retract to tilt the linear member 42B for tilting. After a predetermined time has elapsed, the air supply to the pneumatic cylinder 52B is shut off and the air inside the cylinder is exhausted to the outside, and the rod portion 54B is driven forward to cause slack in the tilting linear member 42B. It is configured.

  Operation | movement of the upright inclination switching apparatus 40 of this auxiliary tool 30 for wire harness assembly is demonstrated.

  First, in the initial state, it is assumed that the rod portions 54A and 54B are in the advanced state and the assembly assisting portion 36 is in the upright posture (see FIG. 4). In this state, at least the upright linear member 42A is in a slack state.

  In this state, when a tilt posture start command is input through the tilt side start switch 62B by an operator or the like, air is supplied to the pneumatic cylinder 52B for a predetermined time, and the rod portion 54B is driven to retract (see FIG. 5). . As a result, the tilting linear member 42B is pulled, and the assembly assisting portion 36 changes its posture from the upright posture to the tilted posture. At this time, the upright linear member 42A is only in a state of being pulled by the slack, and therefore, the assembly assisting portion 36 can be changed to a tilted posture regardless of the upright linear member 42A. . Then, after a predetermined time has elapsed, the air in the pneumatic cylinder 52B is exhausted, the rod portion 54B is driven forward, and the tilting linear member 42B is in a slack state (see FIG. 6).

  In this state, when an operator or the like inputs an upright posture change command through the upright side start switch 62A, air is supplied to the pneumatic cylinder 52A for a predetermined time, and the rod portion 54A is driven to retract (see FIG. 7). . As a result, the upright linear member 42A is pulled, and the assembly assisting portion 36 changes its posture from the tilted posture to the upright posture. At this time, the tilting linear member 42B is only in a state of being pulled by the slack, and therefore, the assembly assisting portion 36 can be changed to an upright posture regardless of the tilting linear member 42B. . Then, after the predetermined time has elapsed, the air in the pneumatic cylinder 52A is exhausted, the rod portion 54A is driven to advance, and the upright linear member 42A is slackened (see FIG. 8).

  According to the upright tilt switching device 40 of the wire harness assembling auxiliary tool configured as described above, the upright linear member 42A, by driving the upright posture changing drive mechanism 50A and the tilting posture changing drive mechanism 50B, When the tilting linear member 42B is pulled, the assembly assisting portion 36 can be changed from the tilted posture to the upright posture or from the upright posture to the tilted posture, and the assembly assisting portion 36 can be easily changed in posture.

  Further, after the posture change, the upright linear member 42A and the tilting linear member 42B are in a slack state, and thus are not affected by the upright linear member 42A, the tilting linear member 42B, or the like. In addition, the posture of the assembly assisting portion 36 can be flexibly changed. That is, it is possible to flexibly change the posture of the assembly assisting portion 36 in that the posture changing operation can be performed manually regardless of the presence of the upright posture changing drive mechanism unit 50A and the tilting posture changing drive mechanism unit 50B. Further, even when the upright posture changing drive mechanism unit 50A and the tilting posture changing drive mechanism unit 50B are separately incorporated, if the operation timing does not overlap, the driving operation is not affected. It is also flexible in that it can be made.

  Further, the upright linear member 42A and the upright posture changing drive mechanism unit 50A, and the tilting linear member 42B and the tilting posture change driving mechanism unit 50B bring the assembly auxiliary unit 36 from the upright posture to the inclined posture, and In addition, the posture can be changed in both directions from a tilted posture to an upright posture.

  However, it is not essential to provide both the upright linear member 42A and the upright attitude changing drive mechanism 50A, and the tilting linear member 42B and the upright attitude changing drive mechanism 50B, and one of them is omitted. However, it is possible to adopt a configuration in which the posture is changed and driven only in one direction.

  For example, in the upright tilt switching device 140 of the wire harness assembling auxiliary tool 30 shown in FIGS. 9 to 13, in the example shown in FIGS. 4 to 8, the upright linear member 42 </ b> A and the upright posture changing drive mechanism unit 50 </ b> A are used. An example is illustrated in which the assembly assisting unit 36 is driven to change the posture from the upright posture to the tilted posture by using the tilting linear member 42B and the tilting posture changing drive mechanism 50B.

  Even in this case, as shown in FIGS. 9 to 12, the assembly assisting portion 36 can be driven to change its posture from the upright posture to the tilted posture in the same manner as described above. Further, in the state where the assembly assisting portion 36 is changed to the tilted posture, as described above, the tilting linear member 42B is in a slack state (see FIG. 13). For this reason, the posture change restrained state of the assembly assisting portion 36 by the tilting linear member 42B is released, and an operator or the like can manually raise the assembly assisting portion 36 to change the posture to the upright state. it can.

  Of course, contrary to the case shown in FIGS. 9 to 13, in the example shown in FIGS. 4 to 8, the tilting linear member 42 </ b> B and the tilting posture changing drive mechanism unit 50 </ b> B are omitted, and the linear member 42 </ b> A for standing. Further, the assembly assisting unit 36 may be driven to change its posture from the tilted posture to the upright posture by the upright posture changing drive mechanism 50A. In this case, an operator or the like may manually change the posture to the tilted posture by tilting the assembly assisting portion 36.

  Based on the above, various modifications based on a more specific application example of the upright tilt switching device for the wire harness assembling aid will be described.

  FIG. 14 is a diagram showing the relationship between the assembly work process of the wire harness WH and the upright tilted state of the wire harness assembly auxiliary tool. Here, as the wire harness assembly auxiliary tool 30 whose posture is changed during the assembly work of the wire harness WH, the terminal holding tool, the work position indicating tool, and the clamp holding tool will be described.

  First, the assembly work of the wire harness WH includes a wiring operation, a bundling operation, a clamp attachment operation, and a wire harness removal operation. By repeating these operations, a plurality of wire harnesses WH are continuously formed. Assembled. The wire wiring work is a work of wiring the electric wires along a predetermined wiring route on the drawing board 22 of the wire harness assembly table 20, and the bundling work is a process of tape-laying a plurality of electric wires. The clamp attaching operation is an operation of attaching and fixing the clamp member to the bundled electric wires. The wire harness removing operation is an operation of removing the wire harness WH accommodated by the assembly from the drawing board 22 of the wire harness assembly table 20.

  During the assembly work of the wire harness WH, the terminal holder is changed to the upright state according to the product number (type) of the wire harness WH before performing the wiring operation, and after the wire harness removal is completed, The posture is changed to the tilted state.

  The reason why the terminal holder is changed to the upright state for each product number will be described more specifically. FIG. 15 is a diagram showing an example of wiring of the wire harness WH, and FIG. 16 is a diagram showing an example of terminal use according to product number.

  As shown in FIG. 15, the basic wiring form of the wire harness WH includes terminals T1, T2, T3, T4, and T5, and terminal holders are disposed at these locations. However, the wire harness WH is not always wired in the same form, and is appropriately wired depending on the grade of the vehicle or the presence or absence of options. For this reason, the wire harness WH of each product number is not necessarily arranged so as to include all the terminals T1, T2, T3, T4, and T5, and may be arranged so as to include a part thereof. For example, in the example shown in FIG. 16, the wire harnesses WH of the product numbers 01 to 04 include terminals T1, T2, T4, and T5, the wire harnesses WH of the product numbers 05 to 08 include terminals T1, T2, and T4, and the product numbers 09 to Twelve wire harnesses WH include terminals T1, T3, and T4.

  For this reason, after assembling each wire harness WH, the terminal holders corresponding to the terminals T1, T2, T3, T4, and T5 that may be changed are tilted, and the assembly object is set before each wire harness WH is assembled. What is necessary is just to make the terminal holder corresponding to terminal T1, T2, T3, T4, T5 according to the product number of the wire harness WH to be in an upright state. That is, the usage pattern of the terminal holder corresponding to the terminals T1, T2, T3, T4, and T5 is three patterns, and according to each pattern, the wire harness WH is in a state in which the necessary terminal holder is upright. If assembly work can be performed, erroneous assembly of the wire harness WH can be suppressed.

  FIG. 17 is an explanatory view showing an upright tilt switching device 240 for realizing the above. Here, the terminal holders which are a kind of the assembly auxiliary tool 30 are terminal holders 230 (T1), 230 (T2) and 230 (T3) corresponding to the terminals T1, T2, T3, T4 and T5. , 230 (T4), 230 (T5).
