1 pair of coloring apparatus carries out painted along the outer surface 5a of the electric wire 5 that arrow P moves.Such electric wire 5 has consisted of the wire harness that will be installed on the similar devices such as motor vehicle or mobile unit.
As shown in Figure 5, electric wire 5 comprises the heart yearn 51 of conduction and the coating layer 52 of electric insulation.Many filament element 51a bindings are to forming together heart yearn 51.Every filament element 51a of heart yearn 51 is made by conducting metal.Heart yearn 51 can be made of single filament element.Coating layer 52 is made by synthetic resin such as polyvinyl chloride.Coating layer 52 is coating heart yearn 51.Thereby the outer surface of coating layer 52 is exactly the outer surface 5a of electric wire 5.
Coating layer 52 has monochromatic color N (indicated such as Fig. 6).Required colouring agent can mix with the synthetic resin of coating layer 52, thus so that the outer surface 5a of electric wire 5 has single color of planting, perhaps as alternative, this monochrome color N can be set to the color of synthetic resin self, thereby need not to add colouring agent in the synthetic resin of coating layer 52.In the latter case, if should monochrome color N be the color of synthetic resin self, then the outer surface 5a of electric wire 5 is called as uncoloured.Thereby " not painted " just means that the outer surface 5a of electric wire 5 is colors of synthetic resin self, does not mix colouring agent in the synthetic resin of coating layer 52.
If it is painted that the outer surface 5a of 1 pair of electric wire 5 of coloring apparatus carries out, then at the outer surface 5a of electric wire 5 formation mark 6 as shown in Figure 6.The color of mark 6 is the first color A (shown in the parallel oblique lines among Fig. 6).The first color A is different from monochromatic color N.The flat shape of mark 6 is the square configuration of fillet substantially, and its vertical (moving direction P of electric wire 5) along electric wire 5 extends.The shape of mark 6 and layout (position on electric wire 5) are definite according to predetermined pattern.
After electric wire cutting machine 10 is cut into regular length with electric wire 5, many wire 5 harnesses are got up, and connect connector in their end, form thus wire harness.Then, the connector of the various electronic devices on this connector and vehicle or the similar device connects, and wire harness-be electric wire 5 sends various signals and powers to electronic device.
In addition, if the first color A of mark 6 is changed to shades of colour (in this embodiment, its be the second to the tenth second colors B in the L any one), just various electric wires 5 can be differentiated mutually.The first to the tenth second colors A is mutually different to L.The color of mark 6 is used as the identification measure of electric wire type in wire harness or the system.That is to say that the first of mark 6 to the tenth second colors A is used to identify the purposes of electric wire 5 in the wire harness on the electric wire 5 to L.
As shown in Figure 1, coloring apparatus 1 has formed mark 6 at the outer surface 5a of electric wire 5.Coloring apparatus 1 is disposed in lax conveying transfer roller 13 1 sides of receiving unit 20, and puts between quilt lax and receive between unit 20 and the conveying transfer roller 13.That is to say that on the moving direction P of electric wire 5, coloring apparatus 1 is disposed in the lax downstream position that receives unit 20, and is positioned at the upstream position of carrying transfer roller 13.
As shown in Figures 2 and 3, coloring apparatus 1 comprises that supporting frame 30, transfer roller member 31, the straight line guiding piece 32 as driver element, cylinder 33, the first to the 12 injection unit 40A are to 40L (partly illustrating), as encoder 34 (seeing Fig. 1) and the control unit 35 (seeing Fig. 1) of detecting unit in Fig. 3.Supporting frame 30 is fixed on the framework 11.Supporting frame 30 extends upward from framework 11.
Transfer roller member 31 is disposed in the top of electric wire 5, and is arranged to vertical vertical with electric wire 5.As shown in Figure 3, transfer roller member 31 comprises that central shaft 31b, transfer roller 31c and the first to the 12 36A are to 36L.Central shaft 31b is made by materials such as potteries, and is made into cylindrical.The end of central shaft 31b is mounted among the bearing 32c in the vertical, and bearing 32c is in the slide block 32b of the straight line guiding piece 32 that hereinafter will introduce, and the end of central shaft is being supported rotationally by slide block 32b.Thereby, transfer roller member 31 supported can rotate.
Transfer roller 31c is made by materials such as potteries, and it is made into the drum of hollow.Transfer roller 31c is disposed in the outside of central shaft 31b.Thereby the periphery wall of transfer roller 31c is the periphery wall 31 of transfer roller member 31.Vertically stretch out from the distal process of transfer roller 31c along it the above-mentioned end of central shaft 31b.The other end of central shaft 31b is disposed in the inside of transfer roller 31c.
Be that the periphery wall of transfer roller member 31 is shaped with the first to the 12 groove 36A to 36L at the periphery wall 31a-of transfer roller 31c, the whole ring Zhou Fangxiang that these grooves are made as at transfer roller member 31 extends.Groove 36A is to arrange along the longitudinally of transfer roller member 31 to 36L, has the gap between these grooves.That is to say that groove 36A is to 36L along arranging abreast with electric wire 5 vertical perpendicular directions.The first to the 12 groove 36A to 36L respectively corresponding the first to the 12 injection unit 40A to 40L.The number of groove is identical with the number of injection unit (12).The arbitrary unit of injection unit 40A in the 40L is ejected into coloured material in the inside of groove 36A respective grooves in the 36L.In addition, each groove 36A can allow electric wire 5 to enter into wherein to the size of 36L, and electric wire 5 is received in the groove.
Transfer roller member 31 with said structure is supported for and can moves in vertical direction.As shown in Figure 4, when painted equipment 1 is worked for forming mark 6, transfer roller member 31 is mobile in vertical direction, so that descend to such an extent that be lower than outer surface 5a (shown in the chain-dotted line among Fig. 4) near the electric wire 5 of transfer roller member 31 near the rear portion diapire 36a (shown in the dotted line among Fig. 4) of the first groove 36A of electric wire 5.Thereby the electric wire 5 outer surface 5a that the rear portion diapire 36a that is positioned at the first groove 36A of electric wire 5 one sides will be positioned at transfer roller member 31 1 sides are downward pushing tow in vertical direction.Like this, the 5 outer surface 5a of the electric wire shown in the chain-dotted line are pushed downwards and push up the position shown in the double dot dash line among Fig. 4 among Fig. 4.
That is to say that the rear portion diapire 36a-of the first groove 36A is that the periphery wall 31a of transfer roller member 31 has realized contacting with the outer surface 5a in the vertical direction of electric wire 5.Like this, be positioned at locational transfer roller member 31 shown in Figure 4 and be supported for like this: along with the movement of electric wire 5 along the arrow P direction, it will rotate in arrow R direction around central shaft 31b.
In addition, transfer roller member 31 is supported as can to move in the horizontal direction.As shown in Figure 5, when painted equipment 1 carried out work with formation mark 6, transfer roller member 31 positioned in the horizontal direction like this: so that the first groove 36A is admitting electric wire 5.
As shown in Figure 3, straight line guiding piece 32 comprises guide rail 32a and slide block 32b.Guide rail 32a is made into rectilinear form.Guide rail 32a flatly arranged, and vertically perpendicular with electric wire 5.But guide rail 32a is supported in the vertical direction by supporting frame 30 and moves.Slide block 32b is being supported by guide rail 32a, and it is supported for and can moves along the longitudinally of guide rail 32a.Utilize the motor of not shown power source-for example to make vertically mobile at guide rail 32a of slide block 32.Transfer roller member 31 is coupled on the slide block 32b.
As slide block 32b during vertically the moving of guide rail 32a, the straight line guiding piece 32 with said structure just so that vertically mobile at guide rail 32a of transfer roller member 31 that is to say so that the transfer roller member is in that vertically vertical directions are mobile with electric wire 5.Like this, when transfer roller member 31 when vertically perpendicular directions move with electric wire 5, straight line guiding piece 32 just with each groove 36A to 36L shift near or away from the injection unit 40A of correspondence to 40L.
Cylinder 33 comprises cylinder main body 33a and the piston rod 33b that can stretch out or retract from cylinder main body 33a.Cylinder main body 33a is fixed on the framework 11, and is disposed in the below of electric wire 5.The movement of electric wire 5 on telescopic piston rod 33b bearing of trend will be away from cylinder main body 33a.The guide rail 32a of straight line guiding piece 32 is coupled on the telescopic piston rod 33b.
When telescopic piston rod 33b stretched out or retracts, the cylinder 33 with said structure just made straight line guiding piece 32 shift near in vertical direction or away from electric wire 5.Because transfer roller member 31 is coupled on the slide block 32b of straight line guiding piece 32, when telescopic piston rod 33b stretched out or retracts, cylinder 33 just shifted near transfer roller member 31 or in vertical direction away from electric wire 5.
As shown in Figures 2 and 3, along the longitudinal arrangement of electric wire 5 the first to the 12 injection unit 40A to 40L, and these injection units are arranged into radially pattern along the ring Zhou Fangxiang of transfer roller member 31.Injection unit 40A is coupled on the injection unit retainer (not shown) that is fixed on the framework 11 to 40L.Injection unit 40A is disposed in lax conveying transfer roller 13 sides of receiving unit 20 to 40L, and receives between unit 20 and the conveying transfer roller 13 lax.That is to say that on the moving direction P of electric wire 5, injection unit 40A is positioned at lax downstream of receiving unit 20 to 40L, but is positioned at the upstream position of carrying transfer roller 13.
The first to the 12 injection unit 40A can be ejected into the first to the 12 coloured material on the periphery wall 31a of transfer roller member 31 respectively to 40L.The first to the 12 kind of coloured material has respectively the first to the 12 kind of color A to L.The first to the tenth second colors A is mutually different to L.Because the first to the 12 injection unit 40A is mutually identical to the structure of 40L basically, hereinafter will be introduced the first injection unit 40A, and extend to all injection units.
The first injection unit 40A comprises the first nozzle 41A and the first valve 42A.As shown in Figure 3, the first nozzle 41A is facing to the periphery wall 31a of transfer roller member 31.Has hole on the first nozzle 41A, this hole of flowing through of the coloured material with first color.This hole extends the periphery wall 31a to transfer roller member 31 as the crow flies.The opening surface of hole is facing to the periphery wall 31a of transfer roller member 31, and the first coloured material flow in the inside of this hole.The feed source 43A of the first coloured material supplies to give described hole with the first coloured material.
As shown in Figure 7, the first valve 42A and is connected with feed source 43A with the first nozzle between the first nozzle 41A and the first coloured material feed source 43A.In addition, the first coloured material feed source 43A also is connected with Compressed Gas source of supply 45.Compressed Gas source of supply 45 is to the delivered inside Compressed Gas of the first coloured material feed source 43A.Incidentally, this Compressed Gas source of supply 45 also is connected to 43L with the second to the 12 coloured material feed source 43B, and is supplied to the second to the 12 coloured material feed source 43B to 43L Compressed Gas.
When the first valve 42A opened, the Compressed Gas that transports from Compressed Gas source of supply 45 was ejected into the first coloured material the first nozzle 41A hole on the periphery wall 31a of transfer roller member 31 through described opening.When the first valve 42A is closed, stop the first coloured material among the first nozzle 41A is ejected.
If the first valve 42A opens in predetermined time according to the signal that comes from the valve-driving circuit 37 (hereinafter will be introduced) in the control unit, the first injection unit 40A that then has said structure will spray to the periphery wall 31a of transfer roller member 31 the first coloured material of ormal weight.Thereby the first injection unit 40A just ejects the first coloured material of ormal weight immediately.Incidentally, " injection " mean that the first liquid coloured material is sprayed outer surface 5a to electric wire 5 by the state with drop.
Similar with the first above-mentioned injection unit 40A, the second to the 12 injection unit 40B also can be ejected into the second to the 12 coloured material of ormal weight on the periphery wall 31a of transfer roller member 31 to 40L.The first to the 12 injection unit respectively with transfer roller member 31 on the first to the 12 groove 36A corresponding to 36L.When straight line guiding piece 32 moved transfer roller member 31 in the horizontal direction, injection unit 40A faced respectively corresponding groove 36A to 36L to the opening of 40L.Like this, injection unit 40A sprays the first to the 12 coloured material on the periphery wall 31a of transfer roller member 31, so that the first to the 12 coloured material is ejected into groove 36A in 36L to 40L.
The first to the 12 above-mentioned coloured material refers to liquid, and in these materials, colouring agent (being used in the organic substance in the industry) is dissolved and be distributed in the solvent.Colouring agent is dyestuff or pigment (their great majority are organic substance or synthetic).Sometimes, " dyestuff " is used as pigment, and " pigment " is used as dyestuff.As for solvent, exist the solvent of the solvent of quick-dry type-for example toluene, and slow curing type-for example aqueous solvent or spirit solvent.As the instantiation of the first to the 12 coloured material, coloured material can be pigmented fluids or coating material.
Pigmented fluids is a kind of like this liquid: therein, dissolved and be distributed in the solvent as the dyestuff of coloured material.Coating material is a kind of like this material: therein, be dispersed in the liquid dispersed agent as solvent as the pigment of coloured material.If undertaken paintedly on the outer surface 5a of electric wire 5 by pigmented fluids, then dyestuff will be penetrated in the coating layer 52 of electric wire 5.If it is painted that the outer surface 5a of electric wire 5 is undertaken by coating material, then pigment will adhere on the outer surface 5a, but can not be penetrated in the coating layer 52 of electric wire 5.Preferably, solvent and liquid dispersed agent have affinity to the synthetic resin that consists of coating layer 52, so that be penetrated into reliably dyestuff in the coating layer 52 or allow pigment to adhere to reliably among the outer surface 5a of electric wire 5.
That is to say that the first to the 12 injection unit 40A utilizes dyestuff that the part of electric wire 5 outer surface 5a is dyeed to 40L, perhaps utilize pigment that the part of electric wire 5 outer surface 5a is applied.Thereby what " for the outer surface 5a to electric wire 5 carries out painted " such statement was expressed is: utilize dyestuff that the part of electric wire 5 outer surface 5a is dyeed, perhaps utilize pigment that the part of electric wire 5 outer surface 5a is applied.
As shown in Figure 1, encoder 34 comprises a pair of rotor 34a.On the moving direction P of electric wire 5, rotor 34a is disposed in the downstream position of carrying transfer roller 13.Each rotor 34a is supported as can to rotate around himself axis.The periphery wall of rotor 34a contacts with the outer surface 5a that is clipped in the electric wire 5 between the two conveying transfer rollers 13.Two rotor 34a are clipped in electric wire 5 between them.When electric wire 5 moved along the arrow P direction, each rotor 34a rotated.The revolution of rotor 34a and electric wire 5 are proportional along the displacement of arrow P direction.
Encoder 34 is connected with the pulse-scaling circuit 35b of the control unit 35 that hereinafter will introduce.If rotor 34a turns over the angle of regulation, encoder 34 is just to control unit 35 output pulse signals.That is to say that the data correspondence that encoder 34 records electric wire 5 along the translational speed of arrow P, and to pulse-scaling circuit 35b output data.That is to say that encoder 34 is by means of electric wire 5 pulse signal corresponding with electric wire 5 displacements with the frictional force output between the rotor 34a.But, if owing to the displacement that makes electric wire 5 due to the situation of electric wire 5 outer surface 5a can't be corresponding the number of pulse, can obtain from another position another speed data of electric wire 5 to feed back, control unit 35 can compare these two data.
As shown in Figure 8, control unit 35 comprises the main body 35a, the pulse-scaling circuit 35b that are contained in the machine box, selects circuit 35c and the first to the 12 valve-driving circuit 37A to 37L as the valve of mnemon and controller.Unit main body 35a is admitting pulse-scaling circuit 35b, valve to select circuit 35c and the first to the 12 valve-driving circuit 37A to 37L.
Pulse-scaling circuit 35b is to counting from the pulse signal of encoder 34 inputs.Pulse-scaling circuit 35b selects circuit 35c to be connected with valve, and it selects the signal of circuit 35c output to represent from the number of the pulse signal of encoder input to valve.In order to increase the resolution of paired pulses, pulse-scaling circuit 35b can be to carrying out frequency division by the very high frequency of encoder 34 pulse signal that produces, and fractional frequency signal is input among the pulse-scaling circuit 35b.
Valve selects circuit 35c to be connected to 37L with valve-driving circuit 37A.When having inputted the pulse signal of predetermined sequence, valve selects circuit 35c with regard to output signal, so that valve-driving circuit 37A opens the valve 42A of correspondence to 37L to 42L.According to the pattern of the mark on electric wire 5 outer surface 5a, valve is selected circuit 35c output signal, so that valve-driving circuit 37A opens valve 42A to 37L to 42L.
That is to say that valve selects circuit 35c to remember following condition: be directed to from each pulse signal of encoder 34 inputs, open one of them valve 42A to 42L, perhaps closeall valve.According to such memory pattern, valve selects circuit 35c that valve-driving circuit 37A is controlled to 37L.Incidentally, if pulse-scaling circuit 35b directly is connected to 37L with valve-driving circuit 37A, then can cancels valve and select circuit 35c.
Thereby valve is selected circuit 35c to remember in advance electric wire 5 outer surface 5a are carried out painted pattern.In addition, in response to the translational speed of the electric wire 5 of inputting from encoder 34, valve selects circuit 35c injection unit 40A to be ejected into the first to the 12 coloured material amount according to the rules on the outer surface 5a of electric wire 5 to 40L according to this memory pattern.Above-mentioned pulse-scaling circuit 35b and valve select circuit 35c to be made of known digital circuit.
Valve-driving circuit 37A is identical to the number of 40L with injection unit 40A to the number of 37L, and valve-driving circuit 37A to 37L respectively corresponding each injection unit 40A to 40L.Injection unit 40A is connected to 37L with corresponding valve-driving circuit 37A by not shown interface to the valve 42L of 40L to 42L.Select circuit 35c input signal with open valve 42A during to 42L when valve, valve-driving circuit 37A just exports start signal to valve 42A to 42L to 37L.When valve-driving circuit 37A to 37L to valve 42A to the 42L output signal when opening corresponding valve 42A to 42L, the valve 42A of correspondence is opened to 42L.Thereby when to valve 42A to the 42L output signal, valve-driving circuit 37A just controls to the opened/closed of 42L corresponding valve 42A to 37L.
When the coloring apparatus 1 with said structure when the outer surface 5a of electric wire 5 forms mark 6-that is to say that outer surface 5a to electric wire 5 carries out at first, will guiding transfer roller 12 to be connected on the framework 11 when painted.Make two cutting blade 15a mutually away from, be wound on the electric wire 5 of guiding on the transfer roller 12 successively through trimming unit 14, laxly receive unit 20 and coloring apparatus 1, and be sandwiched in two and carry between the transfer rollers 13.Then, couple together to 43L and coloring apparatus 1 to the corresponding coloured material feed source 43A of 40L with injection unit 40A.Then, Compressed Gas source of supply 45 couples together to 43L with coloured material feed source 43A.
Then, gas 33 telescopic piston rod 33b stretch out, and transfer roller member 31 is moved upwards up to the position that itself and electric wire 5 are left.Then, the slide block 32b of straight line guiding piece 32 moves, thus with transfer roller member 31 along with electric wire 5 vertically perpendicular directions move.Then, the opening surface of the first injection unit 40A the first nozzle 41A Hole is facing to corresponding groove 36A.Afterwards, the telescopic piston rod 25b of cylinder 25 retracts and transfer roller member 31 moved down makes electric wire 5 be arranged in groove 36A position and make transfer roller member 31 push the position of electric wire 5.Thereby the periphery wall 31a of transfer roller member 31 will push the outer surface 5a that (contact) electric wire 5.
Then, conveying transfer roller 13 rotates and electric wire 5 is vertically pulled out from guiding transfer roller 12 along it.In addition, trimming unit 14 applies the first motivator Q1 to electric wire 5, with electric wire 5 tensionings.Then, 25 pairs in gas drives transfer roller 24 and pushes up pressure, that is to say, applies the second motivator Q2 to electric wire 5.
Then, when the pulse signal of the input predetermined sequence from encoder 34 to pulse-scaling circuit, the first valve-driving circuit 37A that links to each other with the first valve 42A opens the first valve 42A once at official hour.Like this, as shown in Figure 5, the first injection unit 40A is ejected into the first coloured material the inside of respective grooves 36A.
Then, along with the movement of electric wire 5, transfer roller member 31 rotates along arrow R, and the first coloured material among the groove 36A is shifted near electric wire 5.Like this, the first coloured material is rubbed on the outer surface 5a that clips electric wire 5.Thereby, by the first coloured material is rubbed on the outer surface 5a that clips electric wire 5, so that the first coloured material curtain coating becomes very thin homogeneous film shape.
Then, solvent or liquid dispersed agent are evaporated away from the first coloured material; Thus so that electric wire 5 outer surface 5a apply by dyeing or by pigment.Because the first coloured material curtain coating becomes very thin shape, so even solvent or liquid dispersed agent are the slow curing types such as aqueous solvent or spirit solvent, solvent or liquid dispersed agent also can rapid evaporation, fast mummification of coloured material.Thereby as shown in Figure 6, mark on electric wire 5 outer surface 5a 6 moves along arrow P, has carried out painted to the outer surface 5a of electric wire 5.
If control unit 35 is judged the distance that electric wire 5 has moved regulation based on the data that obtain from encoder 34, control unit 35 just stops to carry transfer roller 13.Like this, electric wire 5 just become lax-especially receive between two guide reels 22 of unit 20 lax.Then, the lax telescopic piston rod 25b of the cylinder 25 of unit 20 that receives stretches out, and driven roller 24 is subjected to the effect of the second motivator Q2 and shifts to position shown in dotted lines in Figure 1.Then, the lax of electric wire 5 eliminated in the lax unit 20 that receives.Afterwards, two cutting blade 15a are mutually close, electric wire 5 is clipped in therebetween, and electric wire 5 is cut.Like this, just made the electric wire 5 of the upper mark 6 with the first color A of its outer surface 5a.
If the color of mark 6 is other color (for example the second color B) from the first color change, then when carrying transfer roller 13 to stop, cylinder 33 telescopic piston rod 33b stretch out and transfer roller member 31 are moved up, and that is to say, the transfer roller member is moved on the position of leaving electric wire 5.Then, the slide block 32b of straight line guiding piece 3 moves so that transfer roller member 31 along with electric wire 5 vertically vertical directions move, thereby so that the opening surface of the second injection unit 40B second nozzle 41B Hole facing to the second corresponding groove 36B.Then, cylinder 33 telescopic piston rod 33b retract, so that transfer roller member 31 in the vertical directions move down, thereby electric wire 5 are placed the second groove 36B, so that transfer roller member 31 tops press (contact) electric wire 5.Then, as indicated above, carry transfer roller 13 to rotate.
According to this execution mode, coloring apparatus 1 comprises: its periphery wall 31a and the contacted transfer roller member 31 of electric wire 5 outer surface 5a, and this transfer roller member rotates along with the movement of electric wire 5; The first to the 12 injection unit, they are used for the first to the 12 coloured material is ejected into the periphery wall 31a of transfer roller member 31, and thus, when transfer roller member 31 rotated, coloured material was just rubbed on the outer surface 5a that clips electric wire 5.Thereby the coloured material curtain coating on the electric wire 5 outer surface 5a becomes very thin homogeneous film shape, and the outer surface 5a of electric wire 5 has been carried out painted processing.Thereby, can shorten significantly the drying time of coloured material, can use aqueous solvent or spirit solvent to replace such as quick-dry type solvents such as toluene.Can make environmentally friendly electric wire thus.
In addition, generally, when use contains the coloured material of aqueous solvent or spirit solvent, for this coloured material of mummification rapidly, be provided with a plurality of injection units, these injection units spray the colorant of same color A at the same time, and reduce from the size of the drop of injection unit ejection.But, according to the present invention, utilize the first injection unit 40A and transfer roller member 31 significantly to shorten drying time.Thereby, can reduce the number of injection unit, and reduce cost.In addition, needn't be provided for coloured material is carried out the drying device of mummification, thereby can be used in electric wire 5 be carried out painted equipment realization miniaturization.
Be provided with the first to the 12 injection unit 40A to 40L so that can will have the first to the 12 different colours A be ejected on the periphery wall 31a of transfer roller member 31 to the first to the 12 coloured material of L.Thereby, only by select from injection unit 40A to 40L its spraying pigmented material have the injection unit of required color, and drive, just can change the color of colored pattern.Thereby, can significantly reduce the manual operation that changes color, and greatly shorten the time of color change operation.Thereby, carry out serially electric wire 5 is carried out painted operation.
The first to the 12 injection unit 40A is disposed on the ring Zhou Fangxiang of transfer roller member 31 to 40L.Thereby these injection units 40A can be shifted near transfer roller member 31 equably to 40L.Thereby injection unit 40A can be ejected into coloured material on the outer surface 31a of transfer roller member 31 reliably to 40L.
Periphery wall at transfer roller member 31 is shaped with the first to the 12 groove 36A to 36L, and these grooves are disposed on the ring Zhou Fangxiang of transfer roller member 31.Thereby coloured material is injected into the first to the 12 groove 36A in 36L, and electric wire 5 is disposed in the first to the 12 groove 36A in 36L.Thus, so that coloured material contacts reliably with electric wire 5, thereby can carry out painted to electric wire 5 reliably.In addition, by coloured material being ejected in the groove 36, on the part that coloured material will can not be injected on the transfer roller member 31 not with electric wire 5 contacts.Thereby can reduce coloured material without consumption.
The first to the 12 groove 36A is disposed in electric wire 5 vertically on the perpendicular directions to 36L, and the transfer roller member is along moving with the perpendicular direction of electric wire 5 longitudinal directions, thus can utilize straight line guiding piece 32 make each groove 36A to 36L can both shift near or away from the injection unit 40A of correspondence to 40L.Thereby, can easily make each groove 36A to 36L shift near and away from the injection unit 40A of correspondence to 40L, each injection unit 40A can be ejected into coloured material corresponding groove 36A in 36L reliably to 40L.
Coloring apparatus 1 comprises: for detection of the encoder 34 of electric wire 5 translational speeds; The valve that is used for storage electric wire 5 colored patterns is selected circuit 35c, and this circuit is used for making the first to the 12 injection unit 40A in response to electric wire 5 translational speeds that detected by encoder 34, according to predetermined pattern coloured material to be ejected into the periphery wall 31a of transfer roller member 31 to 40L.Thereby, only by injection unit 40A is controlled to 40L, just can easily change pattern and the layout of colored pattern, and need not to change transfer roller member 31.Thereby, can easily make the electric wire 5 with different colored patterns.
Owing to be provided with the first to the 12 groove 36A to 36L corresponding to the first to the 12 injection unit 40A to 40L, so coloured material just is injected into the groove 36A corresponding with injection unit in 36L.Thereby the coloured material of different colours can not mix, and electric wire 5 can be colored as required color reliably.

In this embodiment, only be shaped with a mark 6, it is substantially the square configuration of fillet.But according to the present invention, mark 6 is not limited to such shape, and mark 6 can be various shapes.For example, the first nozzle 41A can open three times at official hour, thereby three times are ejected into groove 36 inside with the first coloured material, and coloured material is rubbed clip on the electric wire 5.Thus, as shown in Figure 9, formed the shape mark 6 of long straight line, this shape forms by three marks are coupled together.
In addition, in this embodiment, the number of the first to the 12 injection unit 40A to the number of 40L and the first to the 12 groove 36A to 36L all is 12.But according to the present invention, the number of injection unit 40 and groove 36 is not restricted.
In addition, in this embodiment, control unit 35 mainly is made of digital circuit.But according to the present invention, control circuit 35 also can be made of computer, and computer has the EEPROM of known RAM, ROM, CPU and known non-volatile type memorizer-for example.In the case, non-volatile type memorizer-for example EEPROM is as storage element, and CPU is as controller.
In addition, in this embodiment, electric wire 5 is used for forming the wire harness that arranges on the vehicle.But according to the present invention, electric wire 5 can be used on the various electronic devices-computer for example, or be used for various electricapparatus.
In the present invention, for pigmented fluids or coating material, can use various materials-for example acrylic acid coating material, ink (dyestuff or pigment) and UV-ink.
Although above with reference to accompanying drawing the present invention has been done complete illustrating, be understood that to those skilled in the art, can carry out various changes and modification obviously.Thereby, unless these change and modification departing from by the scope of the invention that hereinafter limits, they should be considered to comprise within the scope of the present invention.
