Definitions

  • This invention relates to an apparatus and a method for coloring an outer surface of an electric wire moving in one direction.
  • the motor vehicle is provided with a wiring harness for transmitting power from a power source and control signals from a computer to the electronic devices.
  • the wiring harness includes a plurality of electric wires and connectors attached to an end of the wires.
  • the wire includes an electrically conductive core wire and a coating made of insulating synthetic resin, which coats the core wire.
  • the wire is a so-called coated wire.
  • a connector includes a terminal fitting and a connector housing that receives the terminal fitting therein.
  • the terminal fitting consisting of electrically conductive sheet metal or the like, is attached to an end of the wire and electrically connected to the core wire of the wire.
  • the connector housing made of electrically insulating synthetic resin is formed in a box-shape.
  • the wiring harness When the wiring harness is assembled, first the wire is cut into a specific length and then the terminal fitting is attached to an end of the wire after removing the coating near the end. A wire is connected to another wire according to the need. Afterward, the terminal fitting is inserted into the connector housing, thereby assembling the wiring harness.
  • the wire of the wiring harness must be distinguished in terms of the size of the core wire, the material of the coating (concerning with alteration in the materials depending upon heat-resisting property), and a purpose of use.
  • the purpose of use means, for example, an air bag, antilock brake system (ABS), control signal, and system in a motor vehicle in which the wire is used, such as a power transmission system. Therefore, an outer surface of the electric wire used for the wiring harness is colored by a coloring apparatus for identifying the purpose of the use (for example, see Patent Documents 1 and 2).
  • a coloring apparatus for an electric wire disclosed in Patent Document 1 is installed on an electric wire cutting machine.
  • the electric wire cutting machine cuts the electric wire in a specific length after moving the electric wire in a longitudinal direction.
  • the coloring apparatus for an electric wire includes a plurality of spouting units and a duct having a suction unit.
  • the spouting units spout coloring material having different colors according to a predetermined coloring pattern.
  • the duct is disposed downstream of the coloring apparatus in a moving direction of the electric wire.
  • the coloring apparatus for an electric wire having above described structure deposits the coloring material onto an outer surface of the electric wire according to the coloring pattern with the spouting units while the electric wire cutting machine moves the electric wire in the longitudinal direction, and then, dries the coloring material sufficiently in the duct.
  • a coloring apparatus for an electric wire as disclosed in Patent Document 2 includes a moving unit for moving an electric wire in a longitudinal direction thereof, a tank receiving coloring liquid, a delivery roller, a coloring roller, and a squeegee.
  • the delivery roller is supported rotatably, and a part of the delivery roller is immersed in the coloring liquid received in the tank.
  • the coloring roller is supported rotatably, and disposed at an upper side of the delivery roller and at a lower side of the electric wire to contact both the delivery roller and the electric wire.
  • a plurality of dimples is formed on an outer peripheral wall of the coloring roller.
  • the squeegee is disposed downstream of the coloring roller in the moving direction of the electric wire.
  • the squeegee includes a hole for passing the electric wire, and eliminates the extra coloring liquid deposited on the outer surface of the electric wire.
  • the delivery roller rotates while depositing the coloring liquid on the outer peripheral wall thereof to lead the coloring liquid into insides of the dimples of the coloring roller. Then, the coloring roller deposits the coloring liquid in the dimples onto the outer surface of the electric wire while the moving unit moves the electric wire in the longitudinal direction.
  • Japanese Patent Application 08-184901 is disclosed a marking method of an electric wire for carrying out marking to a wire surface along with the longitudinal direction.
  • An extruding machine for extruding a wire insulating body to the surface of a wire conductor is provided, and while an ink supplying unit for marking the surface of the insulating body is provided in the downstream of the extruding machine.
  • a wire formed with the insulating body is carried in the longitudinal direction by the extruding machine, and while a motor is continuously operated so as to always discharge the ink from a nozzle, and a continuous straight mark can be thereby given to the surface of the insulating body.
  • the ink can be intermittently discharged by turning on and off the motor so as to give a dot mark, and while length and pitch of the mark can be freely adjusted by the operation of motor.
  • Japanese Patent Application 08-184901 discloses a marking device wherein a roll is installed to make following rotation with the feed of an electric wire arranged on a wire feeding line, and under the roll an ink supplying means is installed to supply ink to a circumferential groove provided at the peripheral surface of the roll, and beside it a doctor knife device is furnished to remove the surplus ink supplied to the circumferential groove in the roll.
  • the doctor knife device has an arm to hold a doctor knife as capable of being put in pressure contact with and separated from the circumferential groove, and on the way of this arm a leaf spring is installed which can swing the doctor knife oscillatively in the direction across the width of the roll 22a.
  • Patent Application WO 2007/060832 A1 discloses an electric wire coloring device, by which a mark can be precisely formed at a designated position of an electric wire by restricting a slack of the electric wire.
  • a coloring nozzle spouts a coloring agent toward an outer surface of an electric wire being forwarded along a longitudinal direction of the electric wire.
  • An electric wire suction unit which is for sucking the electric wire so as to prevent the electric wire from slackening, is provided between a guide roll situated nearest to the coloring nozzle among rolls arranged on the upstream side of the coloring nozzle in a forwarding direction K of the electric wire and a delivery roll situated nearest to the coloring nozzle rolls arranged on the downstream side of the coloring nozzle in the forwarding direction K.
  • the spouting unit spouts to deposit the coloring material onto the outer surface of the electric wire. Therefore, if the solvent of the coloring material is the water-type or alcohols solvent, before the coloring material is fully dried, the electric wire contacts peripheral members, and the not-dried coloring material may adhere on such as a roller for moving the electric wire and may be removed from the electric wire. Resultingly, the coloring material deposited on the electric wire may be uneven, or partially removed, and the coloring material adhering on the roller may be deposited again on the outer surface of the electric wire. Accordingly, there is a problem that because the coloring pattern of the electric wire is different from the predetermined pattern, identifying the electric wire becomes difficult.
  • an object of the present invention is to solve these problems. Namely, an object of the present invention is to provide an apparatus and a method for coloring an electric wire whereby the coloring material is quickly dried and is prevented from dropping out from the outer surface of the electric wire to surely identify the electric wires, and the coloring pattern is easily changed.
  • an apparatus for coloring an outer surface of an electric wire moving in one direction including:
  • the apparatus for coloring the electric wire as claimed in claim 1 wherein a plurality of spouting units are provided for spouting coloring material of which colors are different from each other onto the outer peripheral wall of the roller member.
  • the apparatus for coloring the electric wire as claimed in claim 2 wherein the spouting units are arranged in a circumferential direction of the roller member.
  • the apparatus for coloring the electric wire as claimed in claim 4 wherein a plurality of the grooves are arranged perpendicular to a longitudinal direction of the electric wire, and wherein a moving unit is provided for moving the roller member perpendicular to the longitudinal direction so that respective grooves are moved close to and moved away from the corresponding spouting units.
  • a method for coloring an outer surface of an electric wire moving in one direction including the steps of spouting coloring material onto an outer peripheral wall of a roller member; rotating the roller member while the outer peripheral wall of the roller member contacts the outer surface of the electric wire as the electric wire is moved; and rubbing the coloring material onto the outer surface of the electric wire to color the electric wire.
  • the apparatus includes: the roller member of which outer peripheral wall contacts the outer surface of the electric wire, and disposed rotatably as the electric wire moves; and the spouting unit for spouting coloring material onto the outer peripheral wall of the roller member. Therefore, when the roller member is rotated, the coloring material is rubbed onto the outer surface of the electric wire, and the coloring material disposed on the outer surface of the electric wire is extended in a very thin uniform film shape, thereby the outer surface of the electric wire is colored. Therefore, the drying time of the coloring unit is drastically reduced, and the coloring agent having the water-type or alcohols solvent can be used instead of the quick-dry solvent such as toluene. Thus, an environmentally friendly electric wire can be produced.
  • the drying time is drastically reduced with one spouting unit and the roller member. Therefore, the number of the spouting units can be reduced and the cost can be reduced. Further, it is unnecessary to provide a drying device for drying the coloring material, and the apparatus for coloring an electric wire can be downsized.
  • a plurality of spouting units are provided for spouting coloring material of which colors are different from each other onto the outer peripheral wall of the roller member. Therefore, the color of the coloring pattern can be changed only by selecting and driving the spouting unit spouting the coloring material having a desired color among the spouting units. Therefore, manpower for an operation of changing the color is drastically reduced, and the time for the operation of changing the color is drastically reduced. Thus, the coloring of the electric wire can be performed continuously.
  • the spouting units are arranged in a circumferential direction of the roller member. Therefore, every spouting unit can be equally moved near the roller member. Therefore, every spouting unit can surely spout the coloring material onto the outer surface of the roller member..
  • a groove arranged in the circumferential direction is formed on the outer peripheral wall of the roller member. Therefore, the spouting unit spouts the coloring material into the groove, and the electric wire is arranged in the groove. Thereby, the coloring material surely contacts the electric wire to surely color the electric wire. Further, by spouting the coloring material into the groove, the coloring material is not spouted onto a part of the roller member where the electric wire does not contact. Therefore, an amount of useless coloring material is reduced.
  • a plurality of the grooves are arranged perpendicular to a longitudinal direction of the electric wire, and the moving unit is provided for moving the roller member perpendicular to the longitudinal direction so as to respective grooves are moved close to and moved away from the corresponding spouting units. Therefore, each groove is easily moved close to and away from the corresponding spouting unit, and each spouting unit surely spouts the coloring material into the corresponding groove.
  • the method includes the steps of spouting coloring material onto an outer peripheral wall of a roller member; rotating the roller member while the outer peripheral wall of the roller member contacts the outer surface of the electric wire as the electric wire is moved; and rubbing the coloring material onto the outer surface of the electric wire to color the electric wire. Therefore, the coloring material on the outer surface of the electric wire is extended in a very thin uniform film shape to color the electric wire. Therefore, the drying time of the coloring unit is drastically reduced, and the coloring agent having the water-type or alcohols solvent can be used instead of the quick-dry solvent such as toluene. Thus, an environmentally friendly electric wire can be produced.
  • the drying time is drastically reduced with one spouting unit. Therefore, the number of the spouting units can be reduced and the cost can be reduced. Further, it is unnecessary to provide a drying device for drying the coloring material, and the apparatus for coloring an electric wire can be downsized.
