  The remote controller 7 is the same as that of the first embodiment, but has an image displayed on the touch panel display 12 with functions of a start button 71a, a feed button 71b, a return button 71c, an end button 71d, and a numeric keypad 72. It may be allowed. Thereby, the start button 71a, the feed button 71b, the return button 71c, the end button 71d, and the numeric keypad 72 can be omitted, and the remote controller 7 can be downsized.

  FIG. 9 is a block diagram illustrating an example of a control system of the management apparatus 6 according to the second embodiment. The management device 6 includes a control unit 60, a storage unit 61, an input unit 62, a display unit 63, and a communication unit 64, as in the first embodiment. The touch panel display 12 is connected to the communication unit 64.

  The storage unit 61 includes a ROM, a RAM, a hard disk, and the like, and stores image data 611a, management data 612, and the like that are configured in the same manner as the CPU program 610 and the projection image data 611.

  The CPU of the control unit 60 operates as an editing unit by operating according to the program 610. The editing means edits the image data stored in the storage unit 61 based on the editing information input to the Dutch panel display 12.

(Operation and effect of the second embodiment)
According to the second embodiment, similar to the first embodiment, the operations and effects (a) to (d) described above can be achieved, and the image data can be edited. In addition, the display unit can be made smaller than in the first embodiment.

  Note that provisional drawing data corresponding to the assembly process may be used instead of the image data corresponding to the assembly process of the second embodiment. When an operator inputs editing information of a temporary drawing using a touch pen, an electronic pen or the like while keeping the wire harness along the image displayed on the touch panel display 12, the editing unit of the management device 6 inputs the editing information. Based on the information, the temporary drawing data stored in the storage unit is edited. Here, “temporary drawing data” refers to data including drawing information indicating the wiring position of the wire harness and character information instructing the harness assembling work.

[Third Embodiment]
FIG. 10: is sectional drawing which shows the example of a schematic structure of the wire harness manufacturing apparatus which concerns on the 3rd Embodiment of this invention. In the second embodiment, one touch panel display 12 and the remote controller 7 are connected to one management apparatus 6. However, in the present embodiment, a plurality of touch panel displays 12 and a remote controller are connected to one management apparatus 6. 7 are connected directly or via a network such as the Internet.

According to the present embodiment, the following operations and effects are achieved.
(A) The same wire harness assembly or different wire harness assemblies can be simultaneously prepared for a plurality of workers.
(B) Since the management device 6 knows the start time and end time of each process for each worker, it can grasp which worker is delayed, and the number of workers at the delayed worker can be determined. You can support them by increasing them.

  A plurality of touch panel displays 12 may be arranged side by side, and an image for one wire harness assembly may be divided and displayed on the plurality of touch panel displays 12. In this case, it is preferable that there is no gap between the touch panel displays 12.

[Other variations]
The embodiments of the present invention are not limited to the above-described embodiments, and various embodiments are possible without departing from the scope of the present invention. In each said embodiment, although the wiring process of the harness 1, the wiring process of the harness 2, and the wiring process of the harness 3 each switched the image, all the harnesses were displayed by reducing brightness, the said Highlighting such as highlighting may be performed so that only the portion related to the harness is displayed brightly, such as the portion related to the harness is conspicuous.

  Moreover, you may omit a part of component of embodiment of this invention in the range which does not deviate from the summary of this invention. For example, images may be switched from the management device 6 without using the remote controller 7. In the first embodiment, the projected image may be directly projected on the screen without using a mirror.

  In addition, within the scope of the present invention, it is possible to add, delete, change, and replace processes in the assembly process according to the above embodiment.

Industrial application fields

  The present invention is applicable to railway vehicle harnesses, automobile harnesses, medical harnesses, in-device harnesses, and the like.
