  By the way, assembling work for connecting terminals and connectors to the end of the wire harness is generally performed by an operator. Further, tape winding around the wire harness may be performed by an operator, but may be automatically performed by a tape winding machine. Since there are many holders used for the assembly work on the work table where the assembly work is performed, when the tape winding machine is used to wind the tape on the work table, the tape winding machine is moved by the holder. Obstructed and difficult to tape. Therefore, when the assembly work is completed on the work table, the worker removes the wire harness from the work table and transfers it to a dedicated work table for winding the tape.

However, since the wire harness is long and many branch lines branch from the main line portion, it takes time and labor to replace the work table of one line with the work table of the next line. Efficiency is reduced.
This invention is made | formed in view of the situation mentioned above, The objective is to provide the manufacturing line of a wire harness which can perform the manufacturing operation of a wire harness efficiently.

In order to achieve the above-mentioned object, the wire harness production line according to the present invention is characterized by the following (1) to (3).
(1) a work table conveyed by a conveyor and having a wire harness held by a plurality of holders erected on the surface;
A tape winding table provided with a tape winding machine that is laid on the work table that has reached the first predetermined position and wound around the outer periphery of the wire harness while moving along the conveying direction of the conveyor;

According to the wire harness production line having the configuration (1), the holder support base including the additional holder is placed on the work bench at the second predetermined position when the wire harness is operated. Accordingly, it is possible to reduce the number of holders provided in the region where the holder support base on the work table is laterally placed. Therefore, at the first predetermined position, the tape winding machine is transported in a region where there are few holders of the work table when the tape winding machine is placed on the work table and the tape winding machine winds the tape around the wire harness. Tape winding can be performed while moving along the direction.
In this way, the number of holders to be provided on the workbench necessary for assembling the members to be assembled to the wire harness can be reduced, so that the holders are obstructive when winding the tape with a tape winding machine.

The wire harness W is composed of a wire bundle D obtained by bundling a plurality of electric wires and a component P such as a connector or a protector assembled to the wire bundle D. The wire harness W held by the harness holder 21 is arranged at a predetermined height with respect to the surface of the work table 11. In addition, the work table 11 is provided with provision for temporarily placing a member such as a connector to be assembled to the wire harness W or an adhesive tape to be wound around the wire bundle D on the side of the worker S who works in the assembly area A3. The holder 22 is provided.

  The production line 10 includes a tape winding base 30 in the tape winding area A2 and a holder support base 50 in the assembly area A3.

  2A and 2B are diagrams for explaining the tape winding table. FIG. 2A is a schematic plan view of the tape winding machine separated from the work table, and FIG. 2B is a diagram showing the tape winding machine close to the work table. It is a schematic plan view of the state made. FIG. 3 is a perspective view of the tape winding machine for explaining the tape winding machine.

  As shown in FIG. 2A, the tape winding base 30 is placed on the work table 11 that has stopped after reaching the tape winding area (first predetermined position) A2, and the wire harness W of the work table 11 is electrically connected. The tape T is wound around the outer periphery of the bundle D. The tape winding base 30 includes a base 31, a slide base 32 supported by the base 31, and a tape winding machine 33 supported by the slide base 32.

  The slide table 32 is slidable in a direction orthogonal to the transport direction A with respect to the base 31. Two tape winding machines 33 are provided on the slide base 32 and are movable along the transport direction A, respectively. The tape winding machine 33 has a main body portion 35 supported by the slide base 32 and a taping head 36 provided on the main body portion 35. The taping head 36 is advanced and retracted from the main body portion 35 toward the work table 11.

  As shown in FIG. 3, the taping head 36 includes two electric wire gripping portions 37 and a tape winding mechanism portion 38 provided between the electric wire gripping portions 37.

  The electric wire gripping portion 37 has a pair of upper and lower gripping portions 41, and these gripping portions 41 are supported so as to be movable toward and away from each other. These gripping portions 41 have semicircular concave portions 41a, and when the gripping portions 41 are brought close to each other, the wire bundle D of the wire harness W is inserted into the hole formed by the concave portions 41a. Is done. Thereby, the wire bundle D is held by the wire gripping portion 37.

  The tape winding mechanism 38 includes a guide plate 46 having a U-shaped guide recess 45 and a rotating plate 48 having a U-shaped holding recess 47. The wire bundle D gripped by the wire gripping portion 37 is inserted into the guide recess 45 of the guide plate 46 and the holding recess 47 of the rotating plate 48. The rotating plate 48 is rotatably supported with respect to the guide plate 46, and is rotated by a drive motor (not shown). When the rotating plate 48 is rotated, the tape T is drawn out from the annular tape (not shown) set in the tape winding mechanism 38 by the rotating plate 48 and circulates around the wire bundle D.

  When the work table 11 reaches the tape winding area A2 and stops, the tape winding table 30 slides the slide table 32 toward the work table 11 as shown in FIG. The taping head 36 protrudes toward the wire harness W, and the wire bundle D is inserted into the guide recess 45 of the guide plate 46 of the tape winding mechanism 38 and the holding recess 47 of the rotating plate 48.

  In this state, the wire gripping portion 37 of the taping head 36 grips the wire bundle D of the wire harness W, and then the rotating plate 48 of the tape winding mechanism portion 38 rotates while the taping head 36 moves along the transport direction A. Then, the tape T is wound around the wire bundle D. Thereby, the tape T is wound around the wire bundle D in a spiral shape along the longitudinal direction thereof.

  When the tape T is wound around the outer periphery of the electric wire bundle D over a predetermined range, the tape winding base 30 ends the tape winding by the tape winding mechanism unit 38 and releases the holding of the electric wire bundle D by the electric wire holding unit 37. Thereafter, the taping head 36 is pulled toward the main body 35 and the slide base 32 is slid in a direction away from the work table 11.

  Thereafter, the work table 11 holding the wire harness W taped around the wire bundle D by the tape winding table 30 is sent out to the assembly area A3 of the next process by the transport conveyor 13.

  4A and 4B are diagrams for explaining the holding tool support table. FIG. 4A is a schematic plan view showing a state where the slide arm is separated from the work table, and FIG. It is a schematic plan view of a state. FIG. 5 is a side view seen from the downstream side in the transport direction of the work table in a state in which the holder support base is close.

  As shown in FIG. 4A, the holder support base 50 is placed on the work table 11 that has stopped after reaching the assembly area (second predetermined position) A3 on the downstream side of the tape winding area A2. The holder support base 50 has a plurality of additional holders 51. The additional holder 51 holds the wire harness W, a member assembled to the wire harness W, or a member to be assembled to the wire harness W.

When the additional holder 51 holds the wire harness W, the upper part of the additional holder 51 is formed in a U-shape so that the wire harness W can be placed, for example, similarly to the upper part of the harness holder 21. The Therefore, the additional holder 51 functions as a harness holder.
As a case where the additional holder 51 holds a member assembled to the wire harness W, for example, a component P such as a connector already assembled to the wire harness W can be accommodated. Moreover, you may comprise the additional holder 51 so that the clamp of the electric wire which comprises the wire harness W may be hold | maintained. Therefore, the additional holder 51 functions as a receiving jig such as a connector receiving jig or a clamp receiving jig.
Further, as an example of holding a member to be assembled to the wire harness W, the additional holder 51 is wound around a terminal or a connector connected to the electric wire of the electric wire bundle D, or a portion other than the portion wound with the tape winding base 30 It is configured to hold an adhesive tape or the like. The additional holder 51 holds these members for temporary placement when, for example, an operator performs assembly work on the wire harness W.

  The holder support base 50 includes a base 52 and a slide arm 53 supported by the base 52. The slide arm 53 is slidable in the direction of the work table 11 orthogonal to the transport direction A with respect to the base 52. The slide arm 53 includes a support bracket 55 along the transport direction A, and a plurality of arm portions 56 that are fixed to the support bracket 55 and extend to the work table 11 side.

  As shown in FIG. 5, the additional holder 51 is supported by the arm portion 56 of the slide arm 53. The additional holder 51 has a stay 57, and an end portion of the stay 57 is rotatably connected to an end portion of the arm portion 56. Then, the additional holder 51 is movable between an inclined position inclined obliquely and an upright position rising along the vertical direction with respect to the arm portion 56 of the slide arm 53.

  When the work table 11 reaches the assembly area A3 and stops, the holding arm support table 50 slides the slide arm 53 toward the work table 11 as shown in FIG. Then, the additional holder 51 supported by the arm portion 56 of the slide arm 53 is arranged on the work table 11.

  In this state, the worker S performs an assembly operation such as a connection operation of a terminal or a connector to the wire harness W or a winding operation of the tape T. At this time, the operator S uses the provided holding tool 22 provided on the work table 11 and the additional holding tool 51 of the holding tool support base 50, for example, a connector or a tape on the holding tool 22 and the additional holding tool 51. Assembling work to the wire harness W is performed while temporarily placing the member B such as.

  Thereafter, the holder support base 50 slides in a direction in which the slide arm 53 is separated from the work table 11. Then, the work table 11 holding the wire harness W on which the work of assembling the member B is performed by the worker S is transported in the transport direction A by the transport conveyor 13 and sent to the next process.

  As described above, according to the production line 10 according to the present embodiment, when the member B is assembled to the wire harness W, the additional holder 51 is mounted in the assembly area A3 that is the second predetermined position. The provided holder support base 50 is placed on the work table 11. Thereby, the holder 22 provided in the area | region where the holder support base 50 in the work stand 11 is laterally placed can be decreased. Therefore, in the tape winding area A2 which is the first predetermined position, the work table 11 is held when the tape winding table 30 is placed on the work table 11 and the tape winding machine 33 performs tape winding on the wire harness W. Tape winding can be performed while moving the tape winding machine 33 along the conveyance direction A in an area where the tool 22 is small.

  As described above, since the holders 22 to be provided on the work table 11 required when assembling the member B to be assembled to the wire harness W can be reduced, when tape is wound by the tape winding machine 33, The holder 22 does not get in the way, so that the tape winding by the tape winding machine 33 can be performed in-line in the production line 10, and the production work of the wire harness W can be performed efficiently. Therefore, the productivity of the wire harness W can be improved.

  The holder support base 50 includes a slide arm 53 that can slide toward the work table 11 with respect to the base 52. Therefore, the additional holder 51 is brought closer to the work table 11 as necessary by sliding the slide arm 53 with respect to the work table 11 which has reached the assembly area A3 which is the second predetermined position and stopped. Can be easily used.

  In addition, the additional holder 51 is movable between the tilted position and the standing position with respect to the slide arm 53. Therefore, by moving the additional holder 51 between the tilt position and the standing position, the additional holder 51 can be arranged at a position where it can be easily used. Thereby, workability | operativity can be improved further by making the additional holding tool 51 which is not used into a tilting position, for example.

  In the above embodiment, the structure in which the additional holder 51 is brought close to the work table 11 by sliding the slide arm 53 with respect to the base 52 is illustrated. However, the additional holder 51 is provided on the work table 11. It may be possible to attach and detach to the region where the holding tool 22 is small, and in the assembling area A3, the additional holding tool 51 necessary for assembling the member B may be assembled to the work table 11 to perform the assembling work. .

  In the above embodiment, the assembly area A3 is disposed on the downstream side of the tape winding area A2. However, the assembly area A3 is disposed on the upstream side of the tape winding area A2, and the worker operates in the assembly area A3. After performing the assembly work, automatic tape winding by the tape winding machine 33 may be performed in the tape winding area A2.

  Further, the slide arm 53 of the holder support base 50 may be automatically slid or may be manually slid. As a method of sliding automatically, for example, the production line 10 is provided with a position sensor that detects the arrival of the work table 11 to the assembly area A3, and is held when this position sensor detects the work table 11. The slide arm is slid by the drive mechanism provided in the tool support base 50. Further, a work end button to be pressed by the worker S is installed, and when the worker presses the work end button, the drive mechanism of the holder support base 50 separates the slide arm 53 from the work base 11. Try to slide in the direction.
