  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each figure, about the component which has the substantially same function, the same code | symbol is attached | subjected and the duplicate description is abbreviate | omitted.

  FIG. 1 is a perspective view showing a schematic configuration example of a wire harness manufacturing apparatus according to an embodiment of the present invention.

(Overall configuration)
The wire harness manufacturing apparatus 1 includes a display unit 2, a support 3 that supports the display unit 2 from the floor so that the display surface 2a is substantially horizontal, a control device 4 that controls the display unit 2, and a display. A traveling device 5 that travels on the display surface 2 a of the unit 2, and an electric wire supply unit 6 that is disposed in the vicinity of the display unit 2 and supplies electric wires constituting a wire harness on the display surface 2 a of the display unit 2.

  Here, the “wire harness” refers to a bundle of a plurality of electric wires. In addition, you may include what has the connector or terminal for connecting to a printed circuit board or an apparatus in the both ends of each electric wire.

  As the display unit 2, for example, a flat panel display such as a liquid crystal display capable of color display, an organic EL display, or a plasma display can be used. The display unit 2 may use a touch panel display in which a touch panel and a display are combined.

  As shown in FIG. 1, the display unit 2 may be configured by one display, but a plurality of displays may be arranged along the longitudinal direction of the wire harness according to the total length of the wire harness. In the case of using a plurality of displays, the number of displays to be used may be determined according to the total length of the wire harness, and therefore various types of wire harnesses having different total lengths can be easily manufactured. For example, when the size of the display surface 2a is 68 cm in width and 15 m in length, 15 displays with a width of 68 cm and a length of 1 m are arranged in the longitudinal direction. Thus, when using a some display, the image displayed on the display part 2 is divided | segmented, and it displays on each display.

  It is preferable to use a support table 3 having a height that is easy for a person to work on the display surface 2 a of the display unit 2.

  The control device 4 switches the image including the travel guide route for the travel device 5 at a predetermined timing and displays the image on the display unit 2. In addition, the control apparatus 4 may switch the display of the display part 2 by a worker's remote operation.

  The traveling device 5 includes a grip 50 that grips the electric wire 7 and three wheels (one front wheel and two rear wheels) 51. When three wheels are used, the direction in which the traveling device 5 travels can be changed by giving a difference in rotation amount between the two rear wheels. Further, the traveling direction may be changed by changing the direction of the front wheels. Note that the number of wheels 51 is not particularly limited, and two front wheels and two rear wheels may be used as the wheels 51. In this case, the direction of traveling is changed by changing the direction of the front or rear wheels.

  The holding part 50 may hold the electric wire 7 by reducing the size of the hole, or may hold the electric wire 7 by sandwiching it with a clip or a clamp.

  The electric wire supply unit 6 is provided with a bottomed cylindrical accommodating unit 60 that accommodates the electric wire 7 in a state of being wound on the bottom surface, and the electric wire 7 accommodated in the accommodating unit 60. And a reel 61 to be supplied onto the display surface 2a of the display unit 2. When the traveling device 5 travels on the display surface 2a of the display unit 2 along the travel guide path in a state where the electrical wire 7 is gripped by the grip portion 50 of the traveling device 5, the reel 61 rotates and the electrical wire 7 is displayed. Supplied on the display surface 2 a of the unit 2. The reel 61 may include a motor that assists the driving force of the traveling device 5. As a result, the travel device 5 can be downsized.

  FIG. 2 is a block diagram showing a control system of the control device 4. The control device 4 includes an input unit 40 configured with a keyboard, a mouse, and the like, a display unit 41 configured with a liquid crystal display, a control unit 42, a storage unit 43, and the traveling device 5 wirelessly as necessary. And a wireless communication unit 44 for communication. The display unit 2 is connected to the control unit 42.

  The control part 42 is comprised by CPU (Central Processing Unit) etc., and controls the whole wire harness manufacturing apparatus 1 while controlling each part of the control apparatus 4. FIG.

  The storage unit 43 includes a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, and the like, and stores a program 430, image data 431, travel history data 432, and the like.

  The CPU of the control unit 42 operates according to the program 430 and controls each unit of the control device 4 and the entire wire harness manufacturing apparatus 1.

  The control unit 42 travels along the travel guide path with the gripping part 50 of the travel device 5 gripping the electric wire 7, and when it reaches the tip, the rear end of the travel guide path becomes a position where the electric wire 7 is cut. Thus, an image including the travel guide route is displayed on the display unit 2. In addition, when the travel guide path includes a bent portion, the control unit 42 displays a jig image indicating a position where the jig is to be placed inside the bent portion on the display unit 2.

  The image data 431 corresponds to a wire harness ID (identification information) for identifying a wire harness, and includes a plurality of pages corresponding to a wire harness manufacturing process (including a cutting process and an assembly process). The image data 431 includes travel guide paths 23a to 23c (see FIG. 5A and the like) and travel guide paths 24 (see FIG. 7A and the like) for the travel device 5, and a standby mark 21 (see FIG. 4A and the like) indicating a standby position. include. The speed at which the travel device 5 travels is controlled by changing the colors of the travel guide paths 23a to 23c and 24. Further, the opening / closing of the grip portion 50 of the traveling device 5 is controlled by changing the color of the standby mark 21. The colors of the travel guide paths 23 a to 23 c and 24 are an example of information indicating the speed at which the travel device 5 travels. The color of the standby mark 21 is an example of information for instructing opening / closing of the grip portion 50.

  The travel guide path has a certain width (for example, 5 mm), and represents an operation command for the travel device 5 in color, for example, red represents high speed, green represents medium speed, and blue represents low speed. The travel device 5 travels at a high speed (for example, 70 m / min) in a section where the color of the travel guide road is red, travels at a medium speed (for example, 45 m / min) in a green section, and travels at a low speed in a blue section. Travel at (for example, 20 m / min). The traveling device 5 stops traveling at the tip of the traveling guide path, that is, the ground color (for example, white) of the display surface 2a. In the travel guide path, “open”, “close”, and “standby position” as operation commands for the grip portion 50 may be expressed in colors. For example, “open” and “standby position” may be expressed in orange, and “close” and “standby position” may be expressed in brown. Also, when using multiple displays side by side, an image cannot be displayed on the frame of the display, so an operation command that arranges color combinations and ignores color detection and continues the previous operation Can also be done. Thereby, even if there is a display frame, the moving device 5 can be moved to the next display beyond the frame.

  The travel history data 432 is data transmitted from the travel device 5 and is stored in the storage unit 43 as history information in association with the wire harness ID.

  FIG. 3 is a block diagram illustrating an example of a control system of the traveling device 5. The traveling device 5 includes a control unit 52 that controls the entire traveling device 5, a storage unit 53 that includes a ROM, a RAM, and the like, a left wheel motor 54 </ b> A that drives the left wheel 51, and a right wheel 51. The right wheel motor 54B, the gripping motor 55 that drives the gripping unit 50, and the left and right line sensors 56A and 56B that detect the travel guideways as lines displayed on the display unit 2 Is also referred to as a “line sensor 56”), an LED lamp 57 that displays the state of the traveling device 5, and a wireless communication unit 58 that communicates with the control device 4 wirelessly as necessary. The line sensors 56A and 56B are an example of a detection unit that detects color information.

  The storage unit 53 includes a ROM, a RAM, and the like, and stores a program 530, travel history data 531, and the like.

  The CPU of the control unit 52 operates according to the program 530 and controls each unit of the traveling device 5.

  The line sensor 56 uses an LED light source that emits white light using a light emitting diode (hereinafter referred to as “LED”), and light reflected by the display surface 2 a of the display unit 2 from the white light emitted from the LED light source. Three photodiodes for R, G, and B to be detected are configured as a set. The left line sensor 56A is provided on the left side of the front wheel and detects the left edge of the travel guide path. The right line sensor 56B is provided on the right side of the front wheel and detects the right edge of the travel guide path.

  The LED lamp 57 is composed of LEDs that emit RGB colors. The control unit 52 controls the LED lamp 57 to light (continuously or blink) the color corresponding to the color detected by the line sensors 56A and 56B. Thereby, the operator can recognize which state the traveling device 5 is in by looking at the color of the LED lamp 57 lit. For example, the LED lamp 57 lights green and blue at medium speed and low speed, respectively, and turns white and brown according to the opening and closing of the grip portion 50. The LED lamp 57 does not need to be lit because it does not operate on the electric wire while traveling on the return path at high speed.

  For example, the wireless communication unit 58 can use wireless communication such as Wi-Fi (Wireless Fidelity) and Bluetooth (registered trademark).

  For example, when one of the left and right line sensors 56A and 56B detects a color preset as a travel guide path, the control unit 52 detects the color of the left wheel motor 54A and the right wheel so that the other also detects the color. The motor 54B is controlled. As a result, when the left wheel motor 54A and the right wheel motor 54B are controlled so that both the left and right line sensors 56A and 56B detect the same color of the travel guide path, the travel device 5 travels along the travel guide path. Will do. In addition, the control unit 52 stores the color detected by the line sensors 56A and 56B and the time when the color is detected as travel history data 531 in the storage unit 5, and travels at a predetermined timing (for example, a preset time). The history data 531 is transmitted to the control device 4 by the wireless communication unit 58. In addition, the control unit 52 preferably has a calibration function in order to complement the detection by the line sensors 56A and 56B.
