Description

  The present invention relates to a chemical solution container containing a chemical solution such as a coloring material for coloring an article and a chemical solution discharge device including the chemical solution container.

  Various electronic devices are mounted on automobiles or the like as moving bodies. For this reason, the automobile or the like is wired with a wire harness in order to transmit electric power from a power source or the like or a control signal from a computer or the like to the electronic device. The wire harness includes a plurality of electric wires as articles and connectors attached to ends of the electric wires.

  The electric wire includes a conductive core wire and a covering portion made of an insulating synthetic resin that covers the core wire. The electric wire is a so-called covered electric wire. The connector includes a terminal fitting and a connector housing that accommodates the terminal fitting. The terminal fitting is made of conductive sheet metal or the like and is attached to the end of the electric wire to be electrically connected to the core wire of the electric wire. The connector housing is made of an insulating synthetic resin and is formed in a box shape. In the wire harness, the connector housing is coupled to the above-described electronic device or the like, so that each electric wire is electrically connected to the above-described electronic device via the terminal fitting, and transmits desired power and signals to the above-described electronic device. .

  When assembling the wire harness, the electric wire is first cut to a predetermined length, and then the covering portion such as the end of the electric wire is removed (peeled), and the terminal fitting is attached. Connect wires as needed. Thereafter, the terminal fitting is inserted into the connector housing. Thus, the wire harness described above is assembled.

  The wires of the wire harness described above need to identify the size of the core wire, the material of the covering portion (change of the material depending on the presence or absence of heat resistance, etc.), the purpose of use, and the like. The purpose of use is, for example, an automobile system (system) in which electric signals such as airbags, ABS (Antilock Brake System) and vehicle speed information, and power transmission systems are used.

  Therefore, when an electric wire used in a wire harness is extruded and coated around the core wire with the synthetic resin constituting the covering portion described above, a colorant of a desired color is mixed into the synthetic resin constituting the covering portion, The covering portion has been colored in a desired color (for example, see Patent Documents 1 to 3). In this case, when changing the color of the outer surface of an electric wire, it is necessary to stop the extrusion coating apparatus which performs the above-mentioned extrusion coating. In this case, it is necessary to stop the extrusion coating device every time the color of the electric wire is changed, and the time and labor required for the production of the electric wire increase, and the production efficiency of the electric wire tends to decrease.

  Alternatively, the color of the colorant mixed in the synthetic resin has been changed while the extrusion coating apparatus performs extrusion coating. In this case, immediately after changing the color of the colorant, the color of the synthetic resin constituting the covering portion is a color in which the color of the colorant before the change of the covering portion and the color of the colorant after the change are mixed. . For this reason, it was in the tendency for the material yield of an electric wire to fall.

  In order to prevent the reduction in the productivity of the electric wires and the reduction in the material yield of the electric wires, the applicant of the present invention manufactured, for example, a monochromatic electric wire, and if necessary, the outer surface of the electric wire as an article It is proposed that the wire harness is assembled by coloring the desired color (see Patent Document 4). In addition, the applicant of the present invention, when coloring a monochromatic electric wire after manufacture, sprays a liquid coloring material by a certain amount toward the outer surface of the electric wire as an article, and drops the coloring material. Has proposed an electric wire coloring device for coloring an electric wire to a desired color by adhering to the outer surface of the electric wire (see Patent Document 5).

It is attached to the coloring device 1 as a wire processing device). The coloring apparatus 1 is an apparatus that cuts the electric wire 3 as an article into a predetermined length and forms a mark 6 on a part of the outer surface 3a of the electric wire 3 as the article. That is, the coloring device 1 colors the outer surface 3a of the electric wire 3 as an article, that is, marks.

  The electric wire 3 as an article constitutes a wire harness routed in an automobile as a moving body. As illustrated in FIG. 7A, the electric wire 3 includes a conductive core wire 4 and an insulating covering portion 5. The core wire 4 is formed by twisting a plurality of strands. The strand which comprises the core wire 4 is comprised with the electroconductive metal. Moreover, the core wire 4 may be comprised from one strand. The covering portion 5 is made of, for example, a synthetic resin such as polyvinyl chloride (PVC) or polyolefin (PE, PP, etc.). The covering portion 5 covers the core wire 4.

In addition, a desired colorant may be mixed into the synthetic resin constituting the covering portion 5 so that the outer surface 3a of the electric wire 3 may be a single color P, without mixing the colorant into the synthetic resin constituting the covering portion 5. The single color P may be the color of the synthetic resin itself. When the single color P is the color of the synthetic resin itself without mixing the colorant into the synthetic resin constituting the covering portion 5, the covering portion 5, that is, the outer surface 3a of the electric wire 3 is said to be uncolored. As described above, the term “non-colored” means that the outer surface 3a of the electric wire 3 is the color of the synthetic resin itself without mixing the colorant into the synthetic resin constituting the covering portion 5. The outer surface 3a of the electric wire 3 may be uncolored as described above, or may be a single color such as white.

The connector is connected to a connector of various electronic devices such as an automobile, and the wire harness, that is, the electric wire 3 transmits various signals and electric power to each electronic device.

  Moreover, the electric wires 3 can be identified by changing the color B of each point 7 of the mark 6 described above into various colors. In the illustrated example, the color B of all the points 7 is made the same, but the color B may be changed for each point 7 to make the color B different between the points 7 as necessary. The color B of each point 7 of the mark 6 is used for identifying the line type and system (system) of the electric wire 3 of the wire harness.

The delivery roll 12 is rotated at the same rotational speed in opposite directions by a motor (not shown). The pair of delivery rolls 12 sandwich the electric wire 3 between each other and pull the guide roll 11 along the longitudinal direction of the electric wire 3.

  The delivery roll 12 forms a pulling means that pulls and moves the electric wire 3 along the longitudinal direction of the electric wire 3. Thus, the delivery roll 12 moves the electric wire 3 along the longitudinal direction of the electric wire 3, thereby causing the coloring nozzle 31 (described later) of the chemical solution discharge unit 15 and the electric wire 3 to move along the longitudinal direction of the electric wire 3. Move relative. For this reason, the electric wire 3 moves along the arrow K in FIG. 1 from the guide roll 11 toward the delivery roll 12.

The plurality of second rollers 22 are arranged along the horizontal direction (the moving direction K described above) and are arranged below the electric wires 3. As shown in FIG. 1, the first roller 21 and the second roller 22 are arranged in a staggered manner.

  The correction unit 13 sandwiches the electric wire 3 fed from the guide roll 11 by the feed roll 12 between the first roller 21 and the second roller 22. And the correction unit 13 makes the electric wire 3 linear. Further, the correction unit 13 applies a frictional force to the electric wire 3 by being sandwiched between the first roller 21 and the second roller 22.

  That is, the correction unit 13 applies a first biasing force H <b> 1 in the direction opposite to the direction in which the feed roll 12 pulls the electric wire 3 (the movement direction K described above) to the electric wire 3. The first urging force H1 is weaker than the force with which the feed roll 12 pulls the electric wire 3. For this reason, the correction unit 13 applies tension along the longitudinal direction to the electric wire 3.

  The slack absorbing unit 14 is provided on the delivery roll 12 side of the correction unit 13, and is provided between the correction unit 13 and the delivery roll 12. That is, the slack absorbing unit 14 is provided on the downstream side in the movement direction K of the electric wire 3 from the correction unit 13, and is provided on the upstream side in the movement direction K of the electric wire 3 from the delivery roll 12.

  The pair of guide rollers 24 are rotatably supported by the guide roller support frame 23. The guide roller 24 is arranged below the electric wire 3 and guides the electric wire 3 so that the electric wire 3 does not drop out from the moving direction K by contacting the electric wire 3 on the outer peripheral surface. For this reason, the guide roller 24 guides the moving direction K of the electric wire 3.

  The moving roller support frame 25 is fixed to the frame 10. The moving roller support frame 25 is erected upward from the frame 10. The moving roller support frame 25 is provided between the pair of guide roller support frames 23.

That is, the telescopic rod 29 extends from the cylinder body 28 in a direction approaching the electric wire 3.

  A movable roller 26 is attached to the telescopic rod 29. The air cylinder 27 is supplied with pressurized gas into the cylinder body 28, thereby causing the telescopic rod 29, that is, the moving roller 26 to intersect (cross) the moving direction K with a second urging force H 2 (shown in FIG. 1). ) Urge downward along the direction. For this reason, the air cylinder 27 urges the moving roller 26 in a direction approaching the electric wire 3 with the second urging force H2. The second urging force H2 is weaker than the first urging force H1.

  When a later-described pair of cutting blades 48 and 49 of the cutting mechanism 18 approach each other and the electric wire 3 stops once to cut the electric wire 3, the electric wire 3 advances along the arrow K due to inertia. Is loosened between the pair of guide rollers 24. At this time, in the slack absorbing unit 14 configured as described above, since the air cylinder 27 urges the moving roller 26 with the second urging force H2, the telescopic rod 29 of the air cylinder 27 expands, and the moving roller 26 Is displaced to a position indicated by a two-dot chain line in FIG. Then, the slack absorbing unit 14 urges the wire 3 slackened between the above-described guide rollers 24 along a direction orthogonal (crosses) to the moving direction K, absorbs the slack, and stretches the wire 3.

  The second nozzle member 50 is formed in a cylindrical shape. The second nozzle member 50 is made of polyetheretherketone (hereinafter referred to as PEEK). The outer diameter of the second nozzle member 50 is equal to the outer diameter of the first nozzle member 37. Thus, the nozzle 54 is formed in a cylindrical shape, and the coloring material flows inside and communicates with the insert member 35.

  Further, the inner diameter of the second nozzle member 50 is smaller than the inner diameter of the first nozzle member 37. The second nozzle member 50 is arranged coaxially with the first nozzle member 37 and is connected to the first nozzle member 37.

  The second nozzle member 50 is arranged closer to the electric wire 3 than the first nozzle member 37. Further, the space between the first nozzle member 37 and the second nozzle member 50 is watertight.

In the open position, the valve body 44 moves away from the base end portion 37 a and drops the coloring material toward the electric wire 3 through the first nozzle member 37 and the second nozzle member 50. In the closed position, the valve body 44 comes into contact with the base end portion 37 a and restricts the colorant from being sprayed toward the electric wire 3 through the first nozzle member 37 and the second nozzle member 50. The valve body 44 is brought into contact with and separated from the base end portion 37 a to spray the coloring material from the nozzle 54.

  The coil spring 42 urges the disc portion 46 in a direction in which the valve body 44 approaches the proximal end portion 37 a of the first nozzle member 37.

The coloring nozzle 31 sprays the coloring material along the axis. For this reason, the coloring nozzle 31 sprays the coloring material by a certain amount toward the uppermost part of the electric wire 3. The coloring nozzle 31 described above is a nozzle described in the claims.

  As shown in FIG. 2, the chemical solution container 32 is supported by a standing bar 55 provided on the frame 10 and positioned at a predetermined position. The standing bar 55 is, of course, arranged in a state where the longitudinal direction is along the vertical direction. The chemical solution container 32 is provided corresponding to each of the coloring nozzles 31. In the illustrated example, the chemical liquid container 32 and the coloring nozzle 31 correspond one-to-one.

  As illustrated in FIGS. 3 to 5, the chemical liquid container 32 includes an inner container 56, an outer container 57, a pressurized fluid supply pipe 58, and a chemical liquid discharge pipe 59.

The inner container 56 contains a coloring material as a chemical solution and is sealed. That is, the inner container 56 encloses a coloring material and regulates that the coloring material is in direct contact with the external atmosphere.

  As shown in FIG. 11, the inner container 56 is formed into a bag shape with only the upper end as one end opened by the film-like sheet described above, and then, as shown in FIG. Can be removed. Then, as shown in FIG. 13, the upper end of the inner container 56 is closed by thermal welding or the like, and encloses the aforementioned coloring material.

That is, the outer container 57 is made of a deformable material. In the present invention, the outer container 57 is made of a deformable material means that the outer container 57 is made of a material that can be freely deformed such as elastic deformation and plastic deformation. In short, in the present invention, the outer container 57 only needs to be made of a material that is deformed by being pressed.

  In the illustrated example, the outer container 57, like the inner container 56, is a film-like sheet in which an unstretched polyolefin film layer, a stretched nylon film layer, a barrier layer, and a stretched polyethylene terephthalate film layer are laminated in order. It is configured. The outer container 57 is formed such that its width H and height A are larger than the width h and height B of the inner container 56. That is, the outer container 57 is formed larger than the inner container 56.

  The outer container 57 accommodates the inner container 56 and is sealed. That is, the outer container 57 encloses the inner container 56 and restricts the inner container 56 from coming into direct contact with the external atmosphere. The outer container 57 has an inner container 56 positioned at the center thereof. Therefore, the outer container 57 is provided with a plurality of positioning portions 60 formed by welding the constituent film-like sheets. The positioning unit 60 is formed by welding film sheets facing each other, and positions the inner container 56 at the center of the outer container 57.

  As shown in FIG. 14, the outer container 57 is formed into a bag shape with only the upper end as one end opened by the film-like sheet as described above, and then, as shown in FIG. Be contained. The upper end of the outer container 57 is closed by thermal welding or the like, and a positioning portion 60 is formed by thermal welding or the like, and encloses the inner container 56 described above.

  A seal member 61 is attached (attached) to the bottom surface of the outer container 57. The seal member 61 is made of an elastic material such as rubber. The seal member 61 is affixed to a portion of the outer container 57 through which the chemical solution discharge pipe 59 passes.

  The pressurized fluid supply pipe 58 passes through the bottom surface of the outer container 57 and is attached to the outer container 57, that is, the chemical liquid container 32. The pressurized fluid supply pipe 58 communicates the space between the outer container 57 and the inner container 56 with the outer side of the outer container 57, that is, the chemical liquid container 32. A pressurized gas as a pressurized fluid is supplied to the pressurized fluid supply pipe 58 from the pressurized gas supply source 33. Further, a valve 62 is provided between the pressurized fluid supply pipe 58 and the pressurized gas supply source 33. When the valve 62 is opened, the pressurized gas is supplied to the space inside the outer container 57, that is, the space between the outer container 57 and the inner container 56. When the valve 62 is closed, the pressurized gas is supplied to the outer container 57, that is, the outer container 57. Supply to the space between the inner container 56 is stopped.

  The chemical solution discharge pipe 59 is attached to the chemical solution container 32 through the seal member 61, the bottom surface of the outer container 57, and the bottom surface of the inner container 56. The chemical liquid discharge pipe 59 communicates the inside of the inner container 56 with the outer side of the outer container 57, that is, the chemical liquid container 32. The chemical liquid discharge pipe 59 is connected to the inflow pipe 36 of the coloring nozzle 31. When a pressurized gas as a pressurized fluid is supplied into the outer container 57, the chemical liquid discharge pipe 59 discharges the coloring material in the inner container 56 toward the inflow pipe 36, that is, the coloring nozzle 31. That is, the chemical solution discharge pipe 59 is for discharging the coloring material in the inner container 56.

  The pressurized gas supply source 33 is connected to a pressurized fluid supply pipe 58 of the chemical liquid container 32 via a valve 62. The pressurized gas supply source 33 is pressurized as a fluid pressurized into the space between the outer container 57 and the inner container 56 of the chemical liquid container 32 via the valve 62 and the pressurized fluid supply pipe 58. Supply gas. The pressurized gas supply source 33 may be provided corresponding to the plurality of chemical liquid containers 32, and supply pressurized gas to the corresponding chemical liquid containers 32.

  In the chemical solution discharge unit 15 having the above-described configuration, the valve 62 is opened based on a command from the control device 19, and the pressurized gas from the pressurized gas supply source 33 is supplied to the outer container 57 of each chemical solution container 32. Supplied in. Then, in the chemical liquid discharge unit 15, the inside of the outer container 57 is maintained at a predetermined pressure by a command from the control device 19. Then, the coloring material in each chemical solution container 32 is supplied to the coloring nozzle 31.

  And the chemical | medical solution discharge unit 15 of the structure mentioned above is applied to the coil 40 of arbitrary coloring nozzles 31 based on the command from the control apparatus 19, and the valve body 44 mentioned later is the base end part of the 1st nozzle member 37. Leave 37a. And the chemical | medical solution discharge unit 15 sprays the coloring material in the flow path 39 of arbitrary coloring nozzles 31 toward the electric wire 3 by fixed amount.

  In the present specification, a coloring material having a viscosity of 10 mPa · s (millipascal second) or less is used. The colorant mentioned above is a liquid substance in which a colorant (industrial organic substance) is dissolved and dispersed in water or other solvent. Examples of organic substances include dyes and pigments (mostly organic substances and synthetic products). Sometimes dyes are used as pigments and pigments are used as dyes. As a more specific example, the colorant is a coloring liquid or a paint.

  The coloring liquid indicates that the dye is dissolved or dispersed in the solvent, and the paint indicates that the pigment is dispersed in the dispersion. For this reason, when the coloring liquid adheres to the outer surface 3 a of the electric wire 3, the dye penetrates into the covering portion 5, and when the paint adheres to the outer surface 3 a of the electric wire 3, the pigment does not penetrate into the outer covering portion 5. Adhere to 3a.

  That is, the chemical discharge unit 15 dyes a part of the outer surface 3 a of the electric wire 3 with a dye or applies a pigment to the outer surface 3 a of the electric wire 3. For this reason, coloring the outer surface 3a of the electric wire 3 means dyeing (dying) a part of the outer surface 3a of the electric wire 3 and applying a pigment to a part of the outer surface 3a of the electric wire 3. Show.

  Further, the solvent and the dispersion are preferably those having an affinity for the synthetic resin constituting the covering portion 5. In this case, the dye is surely soaked into the covering portion 5, and the pigment is securely adhered to the outer surface 3a.

  Further, the above-described droplet spraying indicates that the liquid colorant is urged and ejected from the coloring nozzle 31 toward the outer surface 3a of the electric wire 3 in a droplet state, that is, a droplet state.

  The duct 16 is provided on the delivery roll 12 side of the chemical solution discharge unit 15, and is provided between the chemical solution discharge unit 15 and the delivery roll 12. That is, the duct 16 is provided on the downstream side in the movement direction K of the electric wire 3 from the chemical solution discharge unit 15, and is provided on the upstream side in the movement direction K of the electric wire 3 from the delivery roll 12. The duct 16 is formed in a cylindrical shape and allows the electric wire 3 to pass inside. A suction means (not shown) such as a vacuum pump is connected to the duct 16. The suction means sucks the gas in the duct 16 and prevents the solvent, the dispersion liquid, and the like in the coloring material from being filled outside the coloring device 1.

  The encoder 17 is provided downstream of the feed roll 12 in the movement direction K of the electric wire 3. As shown in FIG. 1, the encoder 17 includes a pair of rotors 47. The rotor 47 is supported so as to be rotatable around the axis. The outer peripheral surface of the rotor 47 is in contact with the outer surface 3 a of the electric wire 3 sandwiched between the pair of delivery rolls 12. The rotor 47 rotates as the core wire 4, that is, the electric wire 3 travels (moves) along the arrow K. That is, the rotor 47 rotates around the axial core as the core wire 4, that is, the electric wire 3 travels (moves) along the arrow K. Of course, the travel (movement) amount of the core wire 4, that is, the electric wire 3 along the arrow K is proportional to the rotational speed of the rotor 47.

  The encoder 17 is connected to the control device 19. The encoder 17 outputs a pulse signal to the control device 19 when the rotor 47 rotates by a predetermined angle. That is, the encoder 17 outputs information corresponding to the amount of movement of the electric wire 3 along the arrow K toward the control device 19.

  Thus, the encoder 17 measures information according to the amount of movement of the electric wire 3 and outputs information according to the amount of movement of the electric wire 3 toward the control device 19. The normal encoder 17 outputs a pulse signal corresponding to the amount of movement of the electric wire 3 due to the friction between the electric wire 3 and the rotor 47. However, when the amount of movement and the number of pulses do not necessarily match depending on the state of the outer surface 3a of the electric wire 3, speed information may be obtained at another location, the information may be fed back, and a comparison operation may be performed.

  The cutting mechanism 18 is disposed downstream of the pair of rotors 47 of the encoder 17 in the movement direction K of the electric wire 3. The cutting mechanism 18 includes a pair of cutting blades 48 and 49. The pair of cutting blades 48 and 49 are arranged along the vertical direction. The pair of cutting blades 48 and 49 approach or separate from each other along the vertical direction. When the pair of cutting blades 48 and 49 come close to each other, the electric wire 3 fed by the pair of feeding rolls 12 is sandwiched between each other and cut. When the pair of cutting blades 48 and 49 are separated from each other, of course, they are separated from the electric wire 3.

  The control device 19 is a computer including a known RAM, ROM, CPU, and the like. The control device 19 is connected to the feed roll 12, the encoder 17, the cutting mechanism 18, the coloring nozzle 31, that is, the chemical solution discharge unit 15, and the like. By controlling these operations, the entire coloring device 1 is controlled. I control.

  The control device 19 stores a pattern of the mark 6 in advance. The control device 19 opens and closes (controls) the valve 62 to keep the pressure in the outer container 57 at a predetermined pressure that can press the inner container 56 without damaging the outer container 57. When a predetermined pulse signal, that is, information corresponding to the amount of movement of the electric wire 3 is input from the encoder 17, the control device 19 applies a predetermined time to the coil 40 of the coloring nozzle 31 for a predetermined time. The coloring material is sprayed by a certain amount toward the electric wire 3. The control device 19 shortens the time interval for spraying the coloring material from the coloring nozzle 31 when the moving speed of the electric wire 3 increases according to the pattern of the mark 6 stored in advance, and the coloring nozzle 31 when the moving speed of the electric wire 3 decreases. Increase the time interval for spraying the colorant. Thus, the control device 19 colors the electric wire 3 according to a previously stored pattern. Based on the amount of movement of the electric wire 3 measured by the encoder 17, the control device 19 causes the coloring nozzle 31 to spray the coloring material by a certain amount.

  Moreover, if the control apparatus 19 determines with the information from the encoder 17 that the electric wire 3 moved a predetermined amount, after stopping the sending roll 12, the pair of cutting blades 48 and 49 are brought close to each other to cut the electric wire 3.

  When forming the mark 6 on the outer surface 3a of the electric wire 3 with the coloring apparatus 1 having the above-described configuration, that is, when coloring the outer surface 3a of the electric wire 3, the guide roll 11 is first attached to the frame 10. The pair of cutting blades 48 and 49 are separated from each other, and the electric wire 3 wound around the guide roll 11 is passed through the correction unit 13, the slack absorbing unit 14, the chemical solution discharge unit 15, and the duct 16 in order, and the pair of delivery rolls 12. Put in between.

  Further, a pressurized fluid supply pipe 58 and a chemical liquid discharge pipe 59 are pierced (penetrated) into the bottom surface of the outer container 57 containing the inner container 56 filled with a coloring material of a predetermined color, and these are supplied with pressurized gas. The source 33 and the coloring nozzle 31 are connected. And the coloring nozzle 31 is attached to the predetermined location of the unit main body 30 of the chemical solution discharge unit 15. Thereafter, the valve 62 is opened to supply the pressurized gas from the pressurized gas supply source 33 into the outer container 57 of each chemical liquid container 32. Then, as shown in FIGS. 8 and 9, the outer container 57 expands and the outer surface of the inner container 56 is pressed by the pressurized gas. Then, the coloring material in the inner container 56 is supplied to the coloring nozzle 31.

  Then, the feed roll 12 is driven to rotate, the electric wire 3 is pulled from the guide roll 11 and moved along the longitudinal direction of the electric wire 3, and the frictional force of the first urging force H1 is applied to the electric wire 3 by the correction unit 13. And the electric wire 3 is stretched. The moving roller 26, that is, the electric wire 3 is urged by the air cylinder 27 with the second urging force H2.

  When a pulse signal in a predetermined order is input from the encoder 17 to the control device 19, the control device 19 applies a predetermined time to the coil 40 of the coloring nozzle 31 at predetermined intervals. Then, the coloring nozzle 31 sprays the coloring material toward the outer surface 3a of the electric wire 3 by a certain amount.

  And the solvent or dispersion liquid mentioned above evaporates from the coloring material adhering to the outer surface 3a of the electric wire 3, and the outer surface 3a of the electric wire 3 is dyed with a dye, or a pigment is applied to the outer surface 3a. The solvent or dispersion evaporated from the coloring material attached to the outer surface 3 a of the electric wire 3 is sucked into the suction means from the duct 16. Thus, the outer surface 3a of the electric wire 3 is colored.

  When the control device 19 determines that the electric wire 3 having a predetermined length has been sent out based on information from the encoder 17 or the like, the control device 19 stops the sending roll 12. Then, in particular, the electric wire 3 is loosened between the pair of guide rollers 24 of the slack absorbing unit 14, and the moving roller 26 urged by the second urging force H2 is displaced to a position indicated by a two-dot chain line in FIG. . Then, the telescopic rod 29 of the air cylinder 27 of the slack absorbing unit 14 extends. The slack absorbing unit 14 absorbs slack in the electric wire 3.

  Then, the pair of cutting blades 48 and 49 approach each other, and the electric wire 3 is sandwiched between the cutting blades 48 and 49 and cut. In this way, the electric wire 3 in which the mark 6 is formed on the outer surface 3a shown in FIG.

  Further, when the liquid coloring material is sprayed from the coloring nozzle 31 to the outer surface 3a of the electric wire 3 by a predetermined amount, the liquid coloring material flows through the first nozzle member 37 and the second nozzle member 50 along the axis. A part of the coloring material collides with the end surface 50 a of the second nozzle member 50. Then, a part of the coloring material colliding with the end face 50a generates a vortex and stirs the coloring material. And the density | concentration of the coloring material in the 2nd nozzle member 50 is kept uniform.

  Further, when the liquid coloring material is sprayed from the coloring nozzle 31 to the outer surface 3a of the electric wire 3 by a certain amount, when the coloring material enters the first nozzle member 37 from the flow path 39, The pressure of the colorant increases. The pressure of the coloring material is substantially constant in the first nozzle member 37. When a part of the coloring material collides with the end face 50a, the pressure of the coloring material increases rapidly. And if it sprays toward the outer surface 3a etc. of the electric wire 3 from the 2nd nozzle member 50, the pressure of a coloring material will fall rapidly.

  Further, when the liquid colorant is sprayed from the color nozzle 31 to the outer surface 3a of the electric wire 3 by a certain amount, when the colorant enters from the flow path 39 into the first nozzle member 37, The flow rate (speed) of the coloring material is lowered. The flow rate (speed) of the coloring material is substantially constant in the first nozzle member 37, and the flow rate becomes slower and constant toward the second nozzle member 50.

  When a part of the coloring material collides with the end face 50a, the flow rate (speed) of the coloring material increases rapidly. When the droplets are sprayed from the second nozzle member 50 toward the outer surface 3a of the electric wire 3, the speed of the coloring material is kept high. As described above, when the coloring material enters the second nozzle member 50, the pressure and flow velocity (speed) of the coloring material are rapidly increased or increased. Then, the liquid coloring material having a high pressure and a high flow velocity is sprayed toward the outer surface 3 a of the electric wire 3.

  Further, when the coloring material in the inner container 56 decreases, the control device 19 controls the valve 62 to keep the pressure in the outer container 57 at the above-described predetermined pressure. Therefore, as shown in FIG. The container 56 is gradually deflated. For this reason, the coloring material in the inner container 56 can always be pressurized with a constant pressure, and the coloring material can be supplied to the coloring nozzle 31.

  According to this embodiment, since the inner container 56 is sealed, it is possible to prevent the external atmosphere from coming into direct contact with the coloring material as the chemical solution in the inner container 56. Therefore, the colorant can be prevented from being altered.

  Further, since the inner container 56 is made of a deformable material and pressurized gas is supplied into the outer container 57, even if the inner container 56 is sealed, the chemical solution in the inner container 56 is discharged. Can be discharged to the outside.

  Furthermore, since the inner container 56 is made of a deformable material, the inner container 56 can be formed into a bag shape with a synthetic resin or the like. For this reason, the inner container 56 can be made into a simple structure, and the inner container 56 can be disposable. Therefore, it is not necessary to clean and reuse the chemical solution container 32 when replacing and replenishing the chemical solution.

  Therefore, the chemical solution container 32 can have a simple structure, can prevent the color material from being changed as a chemical solution, and can prevent an increase in labor for replacement and replenishment of the color material.

  Since the inner container 56 is formed in a bag shape by a film-like sheet, the cost of the inner container 56 can be reduced. Therefore, the cost of the chemical solution container 32, that is, the chemical solution discharge unit 15 as a whole can be reduced.

  Since the outer container 57 is made of a deformable material, the outer container 57 can be formed into a bag shape with a synthetic resin or the like. For this reason, the outer container 57 can have a simple structure, and in addition to the inner container 56, the outer container 57 can be disposable. Accordingly, it is not necessary to clean and reuse the chemical solution container 32 when replacing and replenishing the chemical solution, and therefore, it is possible to prevent an increase in labor for the replacement and replenishment of the chemical solution.

  Since the outer container 57 is formed in a bag shape by a film-like sheet, the cost of the outer container 57 can be reduced. Therefore, cost reduction of the whole chemical | medical solution container 32 can be achieved.

  Since the sealing member 61 made of an elastic material is attached to a location where the chemical liquid discharge pipe 59 of the outer container 57 penetrates, the elastic restoring force of the seal member 61 causes the outer container 57 and the chemical liquid discharge pipe 59 to be connected. The gap between them is filled. The coloring material in the chemical liquid container 32 can be prevented from leaking from the gap between the chemical liquid discharge pipe 59 and the outer container 57.

  Since the chemical solution discharge unit 15 includes the chemical solution container 32 described above, the chemical solution container 32 can have a simple structure, can be prevented from being deteriorated, and can be replaced and replenished. It is possible to prevent an increase in labor.

  In the above-described embodiment, the inner container 56 is positioned at the center of the outer container 57. However, in the present invention, as shown in FIGS. 16 and 17, the outer container 57 may be provided with a partitioning portion 63 to partition the outer container 57 into two spaces. 16 and 17, the same parts as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The partition part 63 is formed by welding film-like sheets of the outer container 57 facing each other. In the illustrated example, the partition 63 is provided at the center in the width direction of the outer container 57 and extends linearly along the vertical direction, and one partition is provided in the illustrated example. The outer container 57 accommodates the inner container 56 in one space. The tip of the pressurized fluid supply pipe 58 that penetrates the bottom surface of the outer container 57 is positioned in the other space of the outer container 57. The tip of the chemical solution discharge pipe 59 that penetrates the bottom surface of the outer container 57 and the bottom surface of the inner container 56 is positioned in the inner container 56.

  In the case shown in FIG. 16 and FIG. 17, the space in the outer container 57 is partitioned into one space for accommodating the inner container 56 and the other space for nothing, so that the pressurized fluid It is possible to prevent the supply pipe 58 from passing through the bottom surface of the inner container 56 by mistake. Therefore, the inner container 56 can be reliably pressed by the pressurized gas as the pressurized fluid, and the coloring material can be reliably supplied to the coloring nozzle 31. In the case shown in FIGS. 16 and 17, the space inside the outer container 57 is partitioned into one space that houses the inner container 56 and the other space that does not house anything, so the outer container 57. The bottom surface of the inner container 56 and the bottom surface of the inner container 56 may be overlapped. In this case, since the length for inserting the chemical liquid discharge pipe 59 may be short, the chemical liquid container 32 can be easily attached.

  In the above-described embodiment, the inner container 56 is positioned at the center of the outer container 57. However, in the present invention, as shown in FIGS. 18 and 19, the upper end of the outer container 57 and the upper end of the inner container 56 may be overlapped (aligned). In the case shown in FIGS. 18 and 19, the same parts as those of the above-described embodiment are denoted by the same reference numerals and the description thereof is omitted.

  In this case, since the height A of the outer container 57 and the height B of the inner container 56 are determined in advance, the pressurized fluid supply pipe 58 is made shorter than the difference A−B between these heights A and B. What is necessary is just to insert the chemical | medical solution discharge pipe 59 longer than the difference A-B of these height A and B. For this reason, in the case shown in FIG. 18 and FIG. 19, the tip of the pressurized fluid supply pipe 58 can be positioned between the outer container 57 and the inner container 56 reliably and easily, and the chemical solution can be discharged reliably and easily. The tip of the tube 59 can be positioned in the inner container 56. 18 and 19, the upper end of the inner container 56 and the upper end of the outer container 57 may be welded simultaneously, or may be welded individually.

  The coloring material collides with the end face 50a of the second nozzle member 50 and is agitated. Further, since the first nozzle member 37 and the second nozzle member 50 are arranged coaxially and the end face 50a is orthogonal (crossed) to the axis, the colorant is more reliably agitated. For this reason, the density | concentration of the dye or pigment in a coloring material is kept uniform. For this reason, it is possible to prevent the coloring material having an extremely high concentration from adhering to the nozzle 54 of the coloring nozzle 31.

  Moreover, when it penetrates into the 2nd nozzle member 50 from the inside of the 1st nozzle member 37, a coloring material will be pressurized rapidly. For this reason, the coloring material sprayed from the second nozzle member 50 toward the outer surface 3 a of the electric wire 3 is vigorously driven toward the outer surface 3 a of the electric wire 3. For this reason, it is possible to prevent the coloring material from adhering to the second nozzle member 50.

  In this way, since the coloring material can be prevented from adhering to the second nozzle member 50, the coloring material can be reliably sprayed from the second nozzle member 50 toward the outer surface 3a of the electric wire 3 by a certain amount. Further, since it is possible to prevent the coloring material from adhering to the second nozzle member 50, of course, the coloring material adhering to the second nozzle member 50 or the like has an influence on the direction in which the dropped coloring material is sprayed. Can be prevented. Accordingly, the coloring material can be reliably sprayed in a certain amount toward the desired position of the outer surface 3a of the electric wire 3, the desired position of the outer surface 3a of the electric wire 3 can be colored in a desired color, and coloring The location (the point 7 described above) can be maintained in a desired area (size).

  While the electric wire 3 and the coloring nozzle 31 are relatively moved along the longitudinal direction of the electric wire 3, the coloring nozzle 31 sprays the coloring material toward the electric wire 3 by a certain amount. Thus, the electric wire 3 is colored during the relative movement of the electric wire 3 and the coloring nozzle 31. For this reason, since it is not necessary to stop the electric wire 3 in order to color the electric wire 3, work efficiency is not reduced. Further, since the coloring material is sprayed by a certain amount toward the electric wire 3 during the relative movement between the electric wire 3 and the coloring nozzle 31, any position of the electric wire 3 can be colored, and of course, the electric wire 3 is colored continuously. it can.

  The encoder 17 measures the movement amount of the electric wire 3, and the control device 19 controls the coloring nozzle 31 according to the movement amount of the electric wire 3. For this reason, when the moving speed of the electric wire 3 is increased, the interval at which the coloring material is sprayed can be shortened, and when the moving speed of the electric wire 3 is decreased, the interval at which the coloring material is sprayed can be increased. Thus, even if the moving speed of the electric wire 3 changes, the space | interval of the coloring material adhering to the outer surface 3a of the electric wire 3 can be kept constant.

  Therefore, even if the moving speed of the electric wire 3 changes, the coloring material can be attached to the outer surface 3a of the electric wire 3 according to a predetermined pattern. That is, even if the moving speed of the electric wire 3 changes, the electric wire 3 can be colored according to a predetermined pattern.

  In the embodiment described above, the first nozzle member 37 and the second nozzle member 50 are separated from each other. However, in the present invention, the first nozzle member 37 and the second nozzle member 50 may be integrated.

  Furthermore, in this invention, you may use various things, such as an acrylic type coating material, ink (dye type | system | group, pigment type), and UV ink, as a coloring liquid and a coating material.

  Furthermore, in embodiment mentioned above, it has described regarding the electric wire 3 which comprises the wire harness routed to a motor vehicle. However, in the present invention, it is needless to say that the electric wire 3 may be used not only for automobiles but also for various electronic devices such as portable computers and various electric machines.

  In the above-described embodiment, the coloring nozzle 31 that colors the outer surface 3a of the electric wire 3 is shown. However, the coloring nozzle 31 of the present invention may color various things in addition to the electric wire 3.

  Furthermore, in embodiment mentioned above, the chemical | medical solution container 32 which accommodated the coloring material for coloring the outer surface of the electric wire 3 as an article | item is shown. However, in the present invention, various chemical solutions may be accommodated in the chemical solution container 32. In the above-described embodiment, the chemical liquid discharge unit 15 is illustrated as a chemical liquid discharge device that discharges the coloring material. However, in the present invention, various chemical solutions may be discharged.

  Further, in the embodiment described above, pressurized gas as a pressurized fluid is supplied into the outer container 57. However, in the present invention, it is needless to say that various fluids such as liquids as well as gases may be pressurized and supplied into the outer container 57.

  Furthermore, in the above-described embodiment, the outer container 57 is made of a deformable material. However, the outer container 57 may be made of a material that does not deform (not easily deformed, hardly deforms). In short, in the present invention, as long as the inner container 56 can be pressurized from the outside, the outer container 57 to which the pressurized fluid is supplied may be made of any material.

  In the embodiment described above, the coloring nozzle 31 including the valve mechanism 38 is shown as the nozzle. However, the nozzle described in the claims of the present invention may be formed in a simple cylinder or orifice shape that does not include the valve mechanism 38.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
