FIG. 8 is a view showing how the worker arranges the protective tube T taken out of the guide main body 13 in the protective tube alignment portion 20. In FIG. 9, the rubber plug P is fixed to the rubber plug fitting portion 41b by the rubber plug automatic fixing portion 42, and the plurality of protection tubes T are fixed to the plurality of holding main portions 21a by the plurality of protection tube automatic fixing portions 30. FIG. FIG. 10 is a view showing a state in which the operator inserts the electric wire W into the plurality of protective tubes T fixed to the protective tube alignment portion 20. As shown in FIG. FIG. 11 is a view showing how the electric wire W is inserted into the rubber plug P by the rubber plug automatic insertion portion 40. As shown in FIG.

  First, a worker takes out from the guide main body 13 a plurality of protective tubes T automatically sent out from the protective tube cutting and supplying unit 11 to the protective tube supplying and arranging unit 12 (see FIG. 7).

Thereafter, the operator sets the rubber plug P in the rubber plug fitting portion 41b, and aligns and arranges the plurality of protective tubes T taken out from the guide main body portion 13 in the protective tube alignment portion 20 (see FIG. 8).
Here, since the plurality of protection tubes T are aligned in the insertion direction of the electric wire W in the guide main body portion 13 in the corresponding order, the worker can arrange the plurality of protection tubes T in the protection tube alignment portion 20 The wires W can be aligned in the insertion direction and in the corresponding order.
The rubber plug P may be set in the rubber plug fitting portion 41 b before the protective tube T is taken out of the guide main body 13.

After that, the operator automatically fixes the rubber plug P to the holding movable main body portion 41a by pressing the pressing switch as the operation unit 50, and the plurality of protective tubes T are automatically arranged in each of the protective tube aligning / arranging portions 20. It fixes to the holding | maintenance main-body part 21a (refer FIG. 9).
In addition, by the pressing operation of the pressing switch 50 by the operator at this time, the plurality of protective tubes T of the next wire harness WH are automatically supplied from the protective tube cutting and supplying unit 11 to the protective tube supplying and arranging unit 12.

  Thereafter, the worker inserts the electric wire W into the plurality of protective tubes T fixed to the protective tube alignment portion 20 (see FIG. 10). At this time, since each protective tube T is fixed to the protective tube alignment portion 20 in a state in which the wires W are inserted and aligned in a straight line, the operator can easily connect the wires to the plurality of protective tubes T W can be inserted. Further, at the time of the insertion work of the electric wire W into the plurality of protective tubes T, the electric wire automatic fixing portion 43 is not in the way because it is in a standby state at a position not interfering with the electric wire W.

  After that, the operator presses the pressing switch 50 to automatically insert the electric wire W into the rubber plug P by the rubber plug automatic insertion portion 40 (see FIG. 11). When the insertion of the electric wire W into the rubber plug P is completed by the rubber plug automatic insertion portion 40, the fixing of the plurality of protective tubes T and the electric wire W is automatically released. As a result, the operator can take out the wire harness WH from the wire harness manufacturing apparatus 1, and the series of operations is completed.

Next, the process of controlling the operations of the protective tube supply unit 10, the protective tube automatic fixing unit 30, the rubber plug automatic insertion unit 40, etc. of the wire harness manufacturing apparatus 1 performed by the control unit 60 using the flowchart of FIG. Do.

While setting the plurality of protective tubes T in the protective tube alignment portion 20 while completing the work.

First, the control unit 60 determines whether a signal related to an operation is output from the operation unit 50 (step S101). Here, when the control unit 60 determines that a signal related to the operation is output from the operation unit 50 (step S101: Yes), the control unit 60 automatically fixes the plurality of protective tubes T and automatically fixes the rubber plug P (step S102). ).
Specifically, when a signal indicating that the press switch 50 as the operation unit is pressed is output from the press switch 50, the control unit 60 controls the protective tube fixing main bodies of the four protective tube automatic fixing units 30. The driving unit 31 drives the drive unit so as to close the protective tube fitting opening 21c of each holding body unit 21a.
Further, the control unit 60 drives the drive unit so that the rubber plug fixed main body portion 42 a of the rubber plug automatic fixing portion 42 closes the rubber plug fitting opening 41 c of the holding movable main body portion 41 a.

  On the other hand, when the control unit 60 determines that the signal regarding the operation is not output from the operation unit 50 (step S101: No), the determination process of step S101 is repeated.

Thereafter, the control unit 60 determines whether a signal related to the operation is output from the operation unit 50 (step S103). When the control unit 60 determines that the signal related to the operation is output from the operation unit 50 (step S103: Yes), the rubber plug automatic insertion unit 40 automatically inserts the electric wire W into the rubber plug P (step S104). In step S105.
Here, the state in which the rubber plug P is fixed by the rubber plug automatic fixing part 42 while the rubber plug automatic inserting part 40 clamps the electric wire W by the electric wire automatic fixing part 43 moved to the position for clamping the electric wire W from the standby position. The movable movable main body portion 41a is moved so as to insert the electric wire W into the rubber plug P.

  On the other hand, when the control unit 60 determines that the signal regarding the operation is not output from the operation unit 50 (step S103: No), the determination process of step S103 is repeated.

  In step S105, the control unit 60 releases the fixation of the plurality of protective tubes T and the electric wires W, and returns the process to step S101 to repeat the above-described process.
