[0009] [First embodiment] 1 is a schematic diagram showing an example of the schematic configuration of a wire harness manufacturing apparatus 1 according to a first embodiment of the present invention. In this embodiment, a case will be described in which the wire harness manufacturing apparatus 1 is used to manufacture a wire harness for a multi-joint robot whose arms are operated by a plurality of servo motors, but it is also possible to use the wire harness manufacturing apparatus 1 to manufacture wire harnesses used in, for example, automobiles or railway vehicles. Hereinafter, the wire harness manufacturing apparatus 1 will be simply referred to as the manufacturing apparatus 1.

[0010] The manufacturing apparatus 1 includes a horizontally long display unit 2 that displays a wiring diagram (wiring image) showing the configuration of the wire harness to be manufactured in actual size, a fixing jig 3 for fixing some members of the wire harness in the middle of manufacturing, a control device 4 connected to the display unit 2, and an input device 5 connected to the control device 4. The display unit 2 is configured by arranging a plurality of displays 20 in the horizontal direction. In this embodiment, the display unit 2 is configured by arranging two displays 20 in the horizontal direction. The number of displays 20 constituting the display unit 2 may be one or three or more. In FIG. 1, the left-right direction of the drawing corresponds to the horizontal direction of the display unit 2, and the up-down direction of the drawing corresponds to the vertical direction of the display unit 2. Each display 20 is horizontally arranged so that its display surface 20a faces vertically upward. A general-purpose display connected to a personal computer can be used as the display 20, but it is desirable to use a large display, for example, a display exceeding 65 inches, in order to secure a working space.

[0011] The fixing jig 3 has a pair of rails 31, 32 arranged to sandwich the display unit 2 in the vertical direction, a rod-shaped first slider 33 bridging between the pair of rails 31, 32, a plurality of second sliders 34 movable in the vertical direction of the display unit 2 relative to the first slider 33, and a fixing device 35 provided on the second slider 34. The first slider 33 is arranged above the display unit 2 in the vertical direction and is movable in the horizontal direction of the display unit 2 while being guided by the pair of rails 31, 32. The fixing device 35 can hold a connector provided at the end of a cable constituting a wire harness, for example, to fix the position of the display unit 2.

[0012] The first slider 33 has fixing members 331, 332 for fixing its position relative to the pair of rails 31, 32. The second slider 34 has a fixing member 341 for fixing its position relative to the first slider 33. The rails 31, 32 and the first slider 33 are each provided with a scale along its longitudinal direction, and the position of the first slider 33 relative to the rails 31, 32 and the position of the second slider 34 relative to the first slider 33 can be confirmed by using this scale.

[0013] The control device 4 is a computer (personal computer) having an electronic circuit consisting of a microprocessor and its peripheral circuits, and a storage unit 40 such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) for storing electronic information. The storage unit 40 stores a program 400 to be executed by the microprocessor. The microprocessor executes the program 400 to function as a display control unit 41 that controls the display contents of the display unit 2. The display control unit 41 sends, for example, wiring arrangement image data representing a wiring arrangement image to be displayed on the display unit 2 and finished product image data representing a finished product image to the display 20. The display 20 displays the wiring arrangement image and the like according to the wiring arrangement image data.

[0014] The storage unit 40 stores wiring arrangement image data 401 for the display control unit 41 to display the wiring arrangement image on the display 20, finished product image data 402 obtained by photographing the wire harness as a finished product, work procedure information 403, and work progress information 404 indicating the progress of the manufacturing work of the wire harness. The wiring arrangement image data 401 stores information on a wiring arrangement diagram showing the configuration of the wire harness in actual size in each of a plurality of manufacturing processes for each model of the wire harness manufactured using the manufacturing device 1. The finished product image data 402 stores a photographed image of the completed state for each model of the wire harness manufactured using the manufacturing device 1. The work procedure information 403 stores information on the procedure of the work for manufacturing the wire harness in each of a plurality of manufacturing processes for each model of the wire harness manufactured using the manufacturing device 1. The work progress information 404 stores information on the progress of the manufacturing work of the wire harness in each of a plurality of manufacturing processes for each model of the wire harness manufactured using the manufacturing device 1.

[0015] The input device 5 is, for example, a pointing device such as a mouse or a keyboard, and is operated by, for example, a worker who assembles the wire harness to be manufactured. The control device 4 can acquire the contents input or selected by the input device 5. Note that, if the display constituting the display unit 2 is a touch panel display equipped with a touch panel, the touch panel may be used as the input device.

[0016] In this embodiment, in order to effectively utilize the display space of the display unit 2 and efficiently manufacture wire harnesses, the manufacturing apparatus 1 is configured so that a plurality of workers can independently perform the assembly work of the wire harness from both vertical sides of the display unit 2. Specifically, the display control unit 41 can display a plurality of wiring diagrams arranged vertically on the display unit 2, and a worker A arranged on one vertical side and a worker B arranged on the other vertical side can independently perform the assembly work of the wire harness. Note that the workers A and B are not limited to humans, and may be collaborative robots, which are humanoid industrial robots.

[0017] Furthermore, the display control unit 41 can display wiring diagrams of different processes of the same model of wire harness side by side on one vertical side and the other vertical side of the display unit 2 according to the progress of the work of the workers A and B. Next, specific examples of wire harnesses manufactured using the manufacturing apparatus 1 and specific examples of wiring diagrams displayed on the display unit 2 will be described with reference to Figs.

[0018] 2(a) is an external view showing a configuration example of a wire harness 6 manufactured by using the manufacturing apparatus 1. This wire harness 6 is configured by bundling a plurality of cables at a plurality of locations, the cables connecting a plurality of servo motors of an articulated robot and a servo amplifier that supplies drive current to the servo motors. Specifically, the wire harness 6 includes first to fifth power lines 611-615, which are cables for supplying drive current to the servo motors, first to fifth signal lines 621-625, which are cables for transmitting detection signals of resolvers that detect the rotational position of the servo motors, and first to third protective tubes 631-633 that protect parts of these cables in the longitudinal direction, a plurality of bundling members 641-647 that bundle the plurality of cables, and power lines attached to one end of the first to fifth power lines 611-615 on the servo motor side. The wire harness 6 is constituted by the connectors 651-655, the signal line connectors 661-665 attached to one end of the first to fifth signal lines 621-625 on the servo motor side, the servo amplifier side connectors 671-675 attached to the other end of the first to fifth power lines 611-615 and the first to fifth signal lines 621-625, and the mounting bracket 68 bound together with the first and second power lines 611, 612 and the first and second signal lines 621, 622 by a binding member 641. The first to fifth power lines 611-615 and the first to fifth signal lines 621-625 are, for example, a core assembly in which a plurality of insulated electric wires, each having a conductor covered with an insulator, are bundled together and covered with a sheath. In addition, the wire harness 6 may include a resin tube having a circular cross section and an outer diameter equivalent to that of the plurality of cables, which is bundled together with the plurality of cables.

[0019] FIG. 2(b) is an external view showing the wire harness 6 in the process of being assembled, showing the first to third power lines 611-613 to which power line connectors 651-653 are attached, the first to third signal lines 621-623 to which signal line connectors 661-663 are attached, the first protective tube 631, and the mounting bracket 68 in their assembled state.

[0020] Fig. 3 is a schematic diagram showing an example of a display state of the display unit 2. In the example shown in Fig. 3, a wiring diagram 21 showing the configuration of the final process in the assembly of the wire harness 6 is displayed on one vertical side of the display unit 2, and a wiring diagram 22 showing the configuration of the wire harness 6 in the process leading to the state shown in Fig. 2(b) is displayed on the other vertical side.

[0021] The wiring diagram 21 on one side of the vertical direction is displayed so that the state seen by the worker A shown in FIG. 1 is the forward direction, and the wiring diagram 22 on the other side of the vertical direction is displayed so that the state seen by the worker B shown in FIG. 1 is the forward direction. That is, the wiring diagram 22 is displayed in a state inverted with respect to the wiring diagram 21. When the assembly work of the wire harness 6 progresses to the state shown in FIG. 2(b), the worker B inputs to the control device 4 by operating the input device 5 that the work of the process of the wiring diagram 22 displayed on the other side of the vertical direction has been completed. The information on the completion of the work inputted to the control device 4 is stored in the storage unit 40 as work progress information 404. The work progress information 404 is, for example, the name of the worker, the process performed, the date and time when the work was started, the date and time when the work was completed, etc. The display control unit 41 displays the wiring diagram of the next process on the other side of the vertical direction of the display unit 2 in response to the input operation of the worker B.

[0022] FIG. 4 shows the wiring diagram 23 displayed on the other side in the vertical direction when the worker B performs this input operation. In this wiring diagram 23, in addition to the components shown in FIG. 2(b), a fourth power line 614 to which a power line connector 654 is attached, a fourth signal line 624 to which a signal line connector 664 is attached, and a second protective tube 632 are assembled are shown. When the worker B completes the work of this process, the worker B inputs to the control device 4 that the work of the process of the wiring diagram 23 has been completed by operating the input device 5. The information on the completion of the work input to the control device 4 is stored in the storage unit 40 as the work progress information 404. In response to the input operation of the worker B, the display control unit 41 causes the wiring diagram of the next process to be displayed on the other side in the vertical direction on the display unit 2. In this way, the display unit 2 sequentially displays wiring diagrams showing each process in the manufacture of the wire harness 6 according to the progress of the process of the wire harness 6. Similarly, for the wire harness 6 that the worker A is assembling, wiring diagrams showing each process are displayed in sequence according to the progress of the process.

[0023] When information on the completion of one process is stored in the storage unit 40 as the work progress information 404, the display control unit 41 automatically displays the wiring diagram of the next process on the display 20. Furthermore, when information on the completion of one process is stored in the storage unit 40 as the work progress information 404, the display control unit 41 may confirm with the worker whether to display the wiring diagram of the next process on the display 20. In this case, for example, a dialog box is displayed on a display connected to the control device 4, and the worker operates the input device 5 to select either a "Yes" (display) or "No" (do not display) button displayed in the dialog box. When the "Yes" button is selected, the display control unit 41 displays the wiring diagram of the next process on the display 20.

[0024] When the work of the final process is completed and the wire harness 6 is completed, the display control unit 41 displays, in actual size, on the display unit 2, the photographed image of the completed wire harness 6, which has been photographed in advance and stored in the storage unit 40 as finished product image data 402, instead of the wiring diagram 21 showing the configuration of the final process. FIG. 4 shows a state in which the photographed image 24 of the wire harness 6 is displayed on one vertical side of the display unit 2. The worker A compares the wire harness 6 that he assembled with the photographed image 24 displayed on the display unit 2, checks for errors in the type or mounting position of parts such as connectors, missing parts, and errors in the length of each cable, and makes corrections as necessary. Then, when the work of this process is completed, the worker A inputs the presence or absence of errors in the confirmation work to the control device 4 by operating the input device 5. The information input to the control device 4 is stored in the storage unit 40 as work progress information 404.

[0025] As shown in Fig. 3, the wiring diagram 22 includes a gauge diagram 221 that indicates a reference position and tolerance range in the longitudinal direction of the mounting bracket 68 relative to the first power line 611. Fig. 5 is an enlarged view showing this gauge diagram 221 and its surroundings. The gauge diagram 221 is displayed on the display unit 2 together with a symbol 220 that represents the mounting bracket 68 in the wiring diagram 22. The example shown in Fig. 5 illustrates a case in which the gauge diagram 221 is displayed superimposed on the symbol 220.

[0026] The gauge diagram 221 has a reference line 221a indicating the reference position of the mounting bracket 68 when the power line connector 651 attached to the end of the first power line 611 is fixed in a predetermined position by the fixing jig 3 and the first power line 611 is arranged in a straight line along the lateral direction of the display unit 2, and a positive side tolerance line 221b and a negative side tolerance line 221c indicating the maximum allowable positions of the positive and negative side positions.

[0027] Worker B assembles mounting bracket 68 so that the center position of mounting bracket 68 is between plus side tolerance line 221b and minus side tolerance line 221c. The distance between reference line 221a and plus side tolerance line 221b in the horizontal direction of display unit 2 is a dimension corresponding to the plus side tolerance of the assembly position of mounting bracket 68 relative to first power line 611. The distance between reference line 221a and minus side tolerance line 221c in the horizontal direction of display unit 2 is a dimension corresponding to the minus side tolerance of the assembly position of mounting bracket 68 relative to first power line 611.

[0028] As shown in FIG. 3, the wiring diagram 22 includes an enlarged view 222 and a plurality of photographic images 223 and 224 showing details of the bundling portion 60, which is a bundling portion between the first and second power lines 611 and 612 and the first and second signal lines 621 and 622 and the mounting bracket 68 by the bundling member 641. FIG. 6 is an explanatory view showing the enlarged view 222, and FIGS. 7(a) and 7(b) are explanatory views showing the photographic images 223 and 224. The enlarged view 222 and the photographic images 223 and 224 show the configuration of the completed bundling portion 60 in detail so that operational mistakes (for example, mistakes in the type of parts such as connectors or the mounting positions) do not occur when assembling the bundling portion 60. The photographic images 223 and 224 are images of the completed bundling portion 60 taken from different angles. It should be noted that, instead of the photographic images 223 and 224, a perspective view (isometric view) showing the three-dimensional structure of the binding portion 60 by a line diagram or the like may be used.

[0029] 6 and 7(a) and (b), the enlarged view 222 and the photographic images 223 and 224 visually show a configuration of a mounting bracket 68 in which a mounting hole 680 for mounting to a mounting target such as a robot arm and a pair of insertion holes 681 and 682 for inserting a binding member 641 are formed, and a configuration of a binding part 60 in which the first and second power lines 611 and 612 and the first and second signal lines 621 and 622 are bound by the binding member 641 inserted into the insertion holes 681 and 682 of the mounting bracket 68. The binding member 641 is, for example, called a tie wrap or an Insulock (registered trademark), and has a belt-shaped part 641a formed in a belt shape and a locking part 641b through which the belt-shaped part 641a is inserted and which locks the belt-shaped part 641a. Worker B performs the assembly work of the binding portion 60 while referring to the enlarged view 222 and the photographic images 223 and 224.

[0030] In this way, the display control unit 41 can display on the display unit 2 the enlarged view 222 and the photographic images 223 and 224 which enlarge and display the binding portion 60 in the wiring diagram 22. Note that only one of the enlarged view 222 and the photographic images 223 and 224 may be displayed on the display unit 2 as a part of the wiring diagram 22. Also, enlarged views and photographic images may be displayed on the wiring diagram 22 for the binding portions formed by the other binding members 642 to 647.

[0031] As shown in FIG. 3, the display unit 2 displays information on the work procedure, which indicates the procedure of the assembly work of the wire harness 6 in the process corresponding to the wiring diagram 22, as the work procedure manual 225. FIG. 8 is an explanatory diagram showing an example of the work procedure manual 225. In the example shown in FIG. 8, the work procedure of the assembly work includes a step 1 of the bundling work of the bundling part 60, a step 2 of inserting the first and second power lines 611, 612 and the first and second signal lines 621, 622 into the first protective tube 631, and a step 3 of fastening both ends of the first protective tube 631 with bundling members 642, 643 and bundling the first and second power lines 611, 612 and the first and second signal lines 621, 622 together with the first protective tube 631. The work procedure manual 225 is not limited to a still image, and may be a video. This video dynamically shows a sample work procedure using recorded images or animations of a worker actually performing the work.

[0032] When a setting signal for displaying the work procedure manual 225 is input from the worker B, the display control unit 41 displays the work procedure manual 225 on the display unit 2 based on the work procedure information 403 stored in the storage unit 40. Although not shown, for the wiring diagrams 21 and 23, information on the work procedure indicating the procedure of the assembly work in the process corresponding to the wiring diagrams 21 and 23 is displayed as the work procedure manual. The work procedure manual 225 may be included in the wiring diagram 22 in advance. The position where the work procedure manual 225 is displayed can be freely set or changed on the display unit 2. For example, as shown in FIG. 3, the work procedure manual 225 is preferably displayed in a blank portion of the wiring diagram 22 where the assembly work is performed. This allows the worker B to efficiently perform the assembly work while checking the work procedure manual 225.

[0033] The completed wire harness 6 is transferred to an inspection space where an inspection device is located in order to perform an inspection in the inspection process. In the inspection process, the inspection device is used to check the continuity of each cable. When transferring to the inspection space, only the wire harness 6 may be carried, but the wire harness 6 may be moved together with the display unit 2, and various inspections may be performed with the wire harness 6 placed on the display unit 2. In this case, in order to make it easier to move the display unit 2, it is preferable to attach a moving auxiliary member such as a caster with wheels to the support base that supports the display 20 to facilitate movement. In addition, the display unit 2 may display a work procedure manual showing the order in which each connector connected to the terminal of each cable is connected to each connector on the inspection device side, and a connection diagram showing the state of connection with each connector on the inspection device side, in order to perform a continuity check of each cable. This prevents mistakes in the connection method and inspection method in the inspection process of the wire harness 6, which is a combination of many cables, and allows the worker to perform a safer inspection. In addition, the time required for inspection can be shortened.

[0034] According to the first embodiment described above, the display control unit 41 can display a plurality of wiring diagrams arranged in the vertical direction (width direction) of the display unit 2, so that a plurality of workers A and B can independently assemble the wire harness 6 from both sides of the vertical direction of the display unit 2, and the display space of the display unit 2 can be effectively used to efficiently manufacture the wire harness 6. In addition, the wiring diagrams and work procedure manuals displayed on the display unit 2 are switched according to the work progress of the workers A and B, and the wire harness 6 can be assembled, so that it is possible to reduce manpower and labor, or to shorten the time required for the assembly work of the wire harness 6. In addition, the enlarged view 222 and the photographic images 223 and 224 showing the details of the configuration of the bundling part 60 are displayed on the display unit 2, so that it is possible to prevent work mistakes and perform the work smoothly. In addition, information on the work procedure of the process corresponding to the wiring diagram is displayed on the display unit 2, so that it is possible to suppress the occurrence of redoing the work due to a mistake in the work procedure, improve the work efficiency, and improve the quality of the finished product.

[0035] [Second embodiment] Next, a second embodiment of the present invention will be described with reference to Fig. 9 and Fig. 10. In the first embodiment, wiring diagrams of different processes of the same model of wire harness are displayed side by side on one vertical side and the other vertical side of the display unit 2. In the second embodiment, the display control unit 41 displays wiring diagrams of different models of wire harnesses side by side on one vertical side and the other vertical side of the display unit 2.

[0036] 9 is an external view showing a configuration example of the wire harness 7 manufactured on the other vertical side of the display unit 2 in the second embodiment. The wire harness 7 has first to third power lines 711-713, first to third signal lines 721-723, a protective tube 731, a corrugated tube 732, binding members 741-746, first and second power lines 751, 752 that supply power to auxiliary devices of the robot, power line connectors 761-763, signal line connectors 771-773, servo amplifier side connectors 781-783, terminals 791, 792 attached to one ends of the first and second power lines 751, 752, respectively, and a power connector 793 attached to the other ends of the first and second power lines 751, 752.

[0037] Fig. 10 is an explanatory diagram showing a state in which the wiring diagram 21 of the final process of the wire harness 6 described in the first embodiment is displayed on one vertical side of the display unit 2, and the wiring diagram 25 of the final process of the wire harness 7 is displayed on the other vertical side. The wiring diagram 25 on the other vertical side is wider in the vertical direction than the wiring diagram 21 on the one vertical side, and a part of it is displayed on one vertical side of the vertical center line C of the display unit 2 indicated by the dashed line in Fig. 10. The wiring diagram 25 is narrower in the horizontal direction than the wiring diagram 21, and first to fourth thumbnail images 251 to 254, which are reduced images of wiring diagrams corresponding to the respective processes of the wire harness 7 reduced from their actual size, are displayed in the horizontal space of the wiring diagram 25.

[0038] The first thumbnail image 251 is a reduced image of the wiring diagram corresponding to the first manufacturing process of the wire harness 7, and the second thumbnail image 252 is a reduced image of the wiring diagram corresponding to the second manufacturing process of the wire harness 7. The third thumbnail image 253 is a reduced image of the wiring diagram corresponding to the third manufacturing process of the wire harness 7, and the fourth thumbnail image 254 is a reduced image of the wiring diagram corresponding to the final process of the wire harness 7. The actual size wiring diagrams corresponding to the first to third manufacturing processes and the final process are displayed on the display unit 2 in sequence according to the progress of the work of the worker who manufactures the wire harness 7. Each of the first to fourth thumbnail images 251 to 254 may be configured to be enlarged and displayed on the display unit 2 according to the status of the assembly work. In this case, when at least one of the first to fourth thumbnail images 251 to 254 is enlarged and displayed, the image to be enlarged and displayed is enlarged and displayed so as to overlap with each of the other images that are not enlarged and the wiring diagram 25. The wiring diagram 25 may be configured to be displayed in a reduced size. In this case, at least one of the first to fourth thumbnail images 251 to 254 can be enlarged and displayed in the area where the wiring diagram 25 was displayed before being reduced.

[0039] In this way, the display control unit 41 can display wiring diagrams of different models of wire harnesses side by side on one vertical side and the other vertical side of the display unit 2, and can display a plurality of wiring diagrams with different vertical widths side by side in the vertical direction of the display unit 2. The display control unit 41 can also display, on the display unit 2, reduced images of wiring diagrams that are reduced in size compared to the actual size of the wire harness to be manufactured. The display control unit 41 may generate reduced images based on the wiring image data 401 stored in the storage unit 40, or may store reduced images generated in advance in the storage unit 40.

[0040] According to the second embodiment, two different types of wire harnesses can be manufactured in parallel by a plurality of workers. Even if the vertical width of a wiring diagram showing the configuration of one of the two wire harnesses is wider than half the vertical width of the display unit 2, the wiring diagram can be displayed on the display unit 2. Furthermore, since a reduced image of the wiring diagram corresponding to each process, which is reduced from the actual size, is displayed on the display unit 2, for example, a worker can check the work performed in the previous process while working on the display unit 2 and can know in advance the work to be performed in the next process, which contributes to improving the efficiency of work and the quality of the finished product.

[0041] In the example shown in FIG. 10, the first to fourth thumbnail images 251 to 254 are all displayed on the display unit 2.
