Description

  The present invention relates to a wire slack absorbing device and a wire slack absorbing method that absorb slack of an electric wire that moves intermittently along one direction.

  Various electronic devices are mounted on automobiles or the like as moving bodies. For this reason, the automobile and the like route a wire harness in order to transmit electric power from a power source, a control signal from a computer, and the like to the electronic device. The wire harness includes a plurality of electric wires and a connector attached to an end portion 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 houses the terminal fitting. The terminal fitting is made of a 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 connected 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 necessary power and signals to the above-described electronic device. .

  In the wire harness described above, it is necessary to identify the size of the core wire, the material of the covering (such as the presence or absence of heat resistance), the purpose of use, and the like. The purpose of use is, for example, an automobile system (system) in which a control signal such as an air bag or ABS (Antilock Brake System) or an electric wire such as a power transmission system is used. Therefore, the outer surface of the electric wire used for the wire harness is colored in a desired color in order to identify the purpose of use (system) described above.

  When assembling the wire harness, first, the outer surface of the long electric wire wound around the roller is colored to a desired color and cut to a predetermined length, and then the end of the electric wire, etc. Remove the cover (peel) and attach the terminal fitting. Connect wires as needed. Thereafter, the terminal fitting is inserted into the connector housing. Thus, the wire harness described above is assembled.

  As described above, when the outer surface of a long electric wire is colored and the electric wire is cut into a predetermined length, a wire cutting device is used (see, for example, Patent Document 1). This electric wire cutting device includes at least a frame as a device main body, a guide roll, a delivery roll, and a cutting mechanism. A coloring device is attached to the wire cutting device.

  The guide roll is rotatably supported at one end of the frame, and winds a long electric wire before cutting. A pair of delivery rolls are rotatably supported at the other end of the frame. The pair of delivery rolls sandwiches the electric wire between them and pulls the electric wire along the longitudinal direction of the electric wire to move the electric wire. The cutting mechanism is arranged on the downstream side in the moving direction of the electric wire from the delivery roll. The coloring device is disposed between the guide roll and the delivery roll.

  The electric wire cutting device having the above-described configuration intermittently moves the electric wire by a predetermined length by intermittently rotating the pair of delivery rolls. While the electric wire is moving, the outer surface of the electric wire is colored by the coloring device. When the electric wire stops, the electric wire is cut by the cutting mechanism.

  When the electric wire moves intermittently in this way, the electric wire becomes slack due to the inertia of the electric wire when the electric wire stops and when the stopped electric wire moves again. In order to absorb such slack of the electric wire, the slack absorbing device is attached to the electric wire cutting device. The slack absorbing device is provided between the guide roll and the coloring device. The slack absorbing device includes a pair of guide roller support frames, a pair of guide rollers, a moving roller support frame, a moving roller, and an air cylinder.

  The pair of guide roller support frames are fixed to the frame and each support the guide rollers rotatably. The pair of guide rollers are disposed below the electric wires. The moving roller support frame is fixed to the frame and rotatably supports the moving roller. The moving roller is disposed above the electric wire, and is disposed between the pair of guide rollers along the moving direction of the electric wire. The air cylinder includes a cylinder body and a telescopic rod that can be stretched and contracted from the cylinder body. The cylinder body is fixed to the moving roller support frame and is arranged above the electric wire. The telescopic rod expands and contracts from the cylinder body downward (that is, in a direction approaching the electric wire). A movable roller is attached to the telescopic rod.

When the pair of delivery rolls are stopped, the slack in the electric wire between the pair of guide rollers occurs due to the inertia of the electric wire. Then, the slack absorbing device configured as described above absorbs slack by extending the telescopic rod of the air cylinder, displacing the moving roller downward, and urging the electric wire along the direction orthogonal to the moving direction of the electric wire. .
JP 2004-134371 A

  However, in the slack absorbing device having the above-described configuration, the telescopic rod of the air cylinder is extended after the delivery roll is stopped, and the moving roller is displaced downward, so that the wire is once slackened and the wire is loosened. If the outer surface of the loosened electric wire is colored in this way, the coloring pattern is disturbed, which makes it difficult to distinguish between the electric wires because it is different from the predetermined coloring pattern.

  A wire slack absorbing device (hereinafter simply referred to as a slack absorbing device) according to an embodiment of the present invention will be described below with reference to FIGS. In the slack absorbing device 1 according to the embodiment of the present invention, for example, when the outer surface 5a of a long electric wire 5 is colored and the electric wire 5 is cut into a predetermined length, the electric wire 5 is arranged along its longitudinal direction. This is a device that absorbs slackness of the electric wire 5 when it is moved intermittently.

  As illustrated in FIG. 7, the electric wire 5 includes a conductive core wire 51 and an insulating covering portion 52. The core wire 51 is formed by twisting a plurality of strands 51a. The strand 51a which comprises the core wire 51 consists of an electroconductive metal. Moreover, the core wire 51 may be comprised from one strand. The covering portion 52 is made of a synthetic resin such as polyvinyl chloride, for example. The covering portion 52 covers the core wire 51. For this reason, the outer surface of the covering portion 52 forms the outer surface 5 a of the electric wire 5.

  Such a covering portion 52 has a single color N (shown in white in FIG. 7). The outer surface 5a of the electric wire 5 may be made a single color N by mixing a desired colorant into the synthetic resin constituting the covering portion 52, and the colorant is mixed into the synthetic resin constituting the covering portion 52. The single color N may be used as the color of the synthetic resin itself. When the single color N is the color of the synthetic resin itself as in the latter case, the covering portion 52, that is, the outer surface 5 a of the electric wire 5 is said to be uncolored. As described above, the term “non-colored” indicates that the outer surface 5a of the electric wire 5 is the color of the synthetic resin itself without mixing the colorant into the synthetic resin constituting the covering portion 52.

  When the outer surface 5a of the electric wire 5 is colored, a mark 6 as shown in FIG. 7 is formed on the outer surface 5a of the electric wire 5, for example. The color of the mark 6 is a color A (indicated by parallel oblique lines in FIG. 7). The color A is different from the single color N. The shape, arrangement (position on the electric wire 5), etc. of the mark 6 are determined according to a predetermined pattern.

  The electric wire 5 having the above-described configuration is cut at a predetermined length by a cutting mechanism 17 to be described later, and then bundled and a connector or the like is attached to an end or the like to constitute a wire harness. And a connector couple | bonds with a connector of various electronic devices, such as a motor vehicle, and the wire harness, ie, the electric wire 5, transmits various signals and electric power to each electronic device.

  The electric wires 5 can be distinguished from each other by changing the color A of the mark 6 described above to various colors. The color of the mark 6 is a mark for identifying the line type of the electric wire 5 of the wire harness, the system (system), and the like. That is, the color of the mark 6 of the electric wire 5 described above is used to identify the purpose of use of each electric wire 5 of the wire harness.

The guide roll 12 is wound with an electric wire 5 which is long and has no mark 6 formed thereon. The guide roll 12 sends the electric wire 5 in order to the correction unit 14, the slack absorbing unit 20, the coloring unit 30, the duct 15, the encoder 16, and the cutting mechanism 17.

  A pair of delivery rolls 13 is provided at the other end of the frame 11. The pair of delivery rolls 13 are rotatably supported by the frame 11 and are arranged along the vertical direction. The delivery roll 13 is rotated at the same rotational speed in opposite directions by a drive source such as a motor (not shown). The pair of delivery rolls 13 sandwich the electric wire 5 between them, and pull the electric wire 5 from the guide roll 12 along the longitudinal direction of the electric wire 5.

  The delivery roll 13 having the above-described configuration moves the electric wire 5 along the longitudinal direction of the electric wire 5, thereby relatively moving the electric wire 5 and a later-described ejection unit 32 along the longitudinal direction of the electric wire 5. Furthermore, the delivery roll 13 is connected to the control device 40 and repeats rotation and stop according to a command from the control device 40, thereby moving the electric wire 5 intermittently along the longitudinal direction of the electric wire 5. The electric wire 5 moves from the guide roll 12 toward the delivery roll 13 along the direction of arrow P in FIG. The arrow P forms the moving direction P of the electric wire 5.

  The correction unit 14 is provided on the delivery roll 13 side of the guide roll 12 and is provided between the guide roll 12 and the delivery roll 13. That is, the correction unit 14 is provided on the downstream side in the moving direction P of the electric wire 5 from the guide roll 12, and is provided on the upstream side in the moving direction P of the electric wire 5 from the sending roll 13. The correction unit 14 includes a plate-like unit main body 14a, a plurality of first rollers 14b, and a plurality of second rollers 14c. The unit main body 14a is fixed to the frame 11.

The plurality of first rollers 14 b are arranged along the moving direction P of the electric wire 5 and are arranged above the electric wire 5. The plurality of second rollers 14 c are arranged along the moving direction P of the electric wire 5 and are arranged below the electric wire 5. The first roller 14b and the second roller 14c are arranged in a staggered manner.

  The correction unit 14 configured as described above sandwiches the electric wire 5 fed from the guide roll 12 by the feed roll 13 between the first roller 14b and the second roller 14c. And the correction unit 14 makes the electric wire 5 linear. Further, the correction unit 14 applies a frictional force to the electric wire 5 by sandwiching the electric wire 5 between the first roller 14b and the second roller 14c. That is, the correction unit 14 applies a frictional force of the first urging force Q <b> 1 in the direction opposite to the direction in which the delivery roll 13 pulls the electric wire 5 (the moving direction P of the electric wire 5) to the electric wire 5. The first urging force Q1 is weaker than the force with which the delivery roll 13 pulls the electric wire 5. For this reason, the correction unit 14 applies tension along the longitudinal direction of the electric wire 5 to stretch the electric wire 5.

  The slack absorbing unit 20 absorbs slack of the electric wire 5 that moves intermittently along the arrow P. The slack absorbing unit 20 is provided on the delivery roll 13 side of the correction unit 14, and is provided between the correction unit 14 and the delivery roll 13.

  The guide roller support frame 21 is fixed to the frame 11. The guide roller support frame 21 is erected upward from the frame 11. The pair of guide roller support frames 21 are arranged along the moving direction P of the electric wire 5 with a space therebetween.

  Each of the pair of guide rollers 22 is rotatably supported by the guide roller support frame 21. The guide roller 22 is arranged below the electric wire 5 and guides the electric wire 5 so that the outer peripheral surface of the guide roller 22 is in contact with the electric wire 5 so that the electric wire 5 is not dropped from the moving direction P of the electric wire 5. For this reason, the guide roller 22 guides the moving direction P of the electric wire 5.

  The pressing portion support frame 23 is fixed to the frame 11. The pressing portion support frame 23 is erected upward from the frame 11. The pressing portion support frame 23 is provided in the vicinity of the pair of guide roller support frames 21.

  The pressing unit 24 includes a linear guide 26, a driving unit 29, a roller member 27, and a brake unit (not shown). The linear guide 26 is attached to the pressing portion support frame 23. The linear guide 26 includes a rail 26a and a slider 26b. The rail 26 a is fixed to the outer surface of the pressing portion support frame 23. The rail 26a is formed in a straight line and is provided along the vertical direction. The slider 26b is supported by the rail 26a so as to be movable along the longitudinal direction of the rail 26a. An air cylinder 25 as urging means is attached to the slider 26b.

  The air cylinder 25 includes a cylinder main body 25a and an expansion / contraction rod 25b that can be expanded and contracted from the cylinder main body 25a. The cylinder body 25 a is fixed to the slider 26 b and is disposed above the electric wire 5. The telescopic rod 25b extends downward from the cylinder body 25a along the vertical direction. That is, the telescopic rod 25b extends from the cylinder body 25a in a direction approaching the electric wire 5.

  A roller member 27 is attached to the telescopic rod 25b of the air cylinder 25 configured as described above. The air cylinder 25 always urges the telescopic rod 25b, that is, the roller member 27 downward along the vertical direction with the second urging force Q2 when the pressurized gas is supplied into the cylinder body 25a. Thus, the air cylinder 25 always urges the roller member 27 toward the electric wire 5 with the second urging force Q2. The second urging force Q2 is weaker than the first urging force Q1.

  The drive unit 29 includes a motor 29a as a drive source, a screw shaft 29b, and a nut 29c. The motor 29 a is fixed to the pressing portion support frame 23. The screw shaft 29b is arranged along the vertical direction. One end of the screw shaft 29b is connected to the output shaft of the motor 29a, and the other end of the screw shaft 29b is supported by a bearing 29d fixed to the pressing portion support frame 23. As described above, the screw shaft 29b is supported by the pressing portion support frame 23 so as to be rotatable about the axis. The nut 29c is screwed to the screw shaft 29b and is fixed to the slider 26b.

  When the motor 29a of the drive unit 29 having the above-described configuration is operated, the output shaft of the motor 29a rotates, the screw shaft 29b rotates, the nut 29c moves along the vertical direction, and the slider 26b moves in the longitudinal direction of the rail 26a. That is, it moves along the vertical direction. When the slider 26b moves along the vertical direction, the air cylinder 25 fixed to the slider 26b moves along the vertical direction, and the roller member 27 attached to the telescopic rod 25b of the air cylinder 25 moves along the vertical direction. To do. Thus, the drive unit 29 moves the roller member 27 along the vertical direction.

  The roller member 27 is rotatably supported by the telescopic rod 25b of the air cylinder 25 and is supported by the air cylinder 25 and the linear guide 26 so as to be movable along the vertical direction. The roller member 27 is disposed above the electric wire 5 and is disposed in the center between the pair of guide rollers 22. The roller member 27 is supported so as to be movable along a direction orthogonal (crossing) to the moving direction P of the electric wire 5 by being supported so as to be movable along the vertical direction. The roller member 27 presses the electric wire 5 when the drive unit 29 moves the slider 26b downward along the vertical direction according to a command from the control circuit 43, and the outer peripheral surface of the roller member 27 contacts with the outer surface 5a of the electric wire 5 and rotates. It is provided freely.

  The brake unit stops the rotation of the roller member 27 described above, and is, for example, a known powder brake or friction plate brake. The brake unit is operated by a command from the control circuit 43 when the electric wire 5 is stopped or started to move, for example, to stop the rotation of the roller member 27 and cause the roller member 27 to press the electric wire 5 more reliably. As long as the brake part stops the rotation of the roller member 27, the mechanism may be mechanical or electromagnetic.

  When a pair of cutting blades 17a described later of the cutting mechanism 17 approach each other and the electric wire 5 stops once to cut the electric wire 5, the electric wire 5 advances along the arrow P due to inertia. Between the guide rollers 22. The pressing portion 24 of the slack absorbing unit 20 having the configuration described above moves the roller member 27 downward along the vertical direction as the slider 26b moves downward along the vertical direction from the initial position immediately before the electric wire 5 stops. However, the roller member 27 starts to press the electric wire 5 along the vertical direction (indicated by a two-dot chain line in FIG. 2). Further, the roller member 27 presses the electric wire 5 along the vertical direction even after the electric wire 5 stops, and absorbs the slackness of the electric wire 5. The vertical direction corresponds to a direction orthogonal (crossing) to the moving direction P of the electric wire 5.

  When the electric wire 5 stops, the telescopic rod 25b of the air cylinder 25 extends to urge the roller member 27 toward the electric wire 5 with the second urging force Q2, thereby applying a certain tension to the electric wire 5. In this way, the slack absorbing unit 20 absorbs slack of the electric wire 5 and gives a constant tension to the electric wire 5 from just before the electric wire 5 stops to after it stops.

  Further, when the stopped electric wire 5 moves again, the electric wire 5 tries to loosen due to inertia. The pressing portion 24 of the slack absorbing unit 20 having the above-described configuration absorbs the slack of the electric wire 5 stopped as described above, and the air cylinder 25 applies a certain tension to the electric wire 5. The pressing portion 24 starts to move the electric wire 5 and the slider 26b starts to move upward along the vertical direction. At this time, the roller member 27 presses the electric wire 5 along the vertical direction. Further, while the telescopic rod 25b of the air cylinder 25 is contracted, the roller member 27 is urged toward the electric wire 5 by the second urging force Q2, and a certain tension is applied to the electric wire 5. And when the electric wire 5 moves and predetermined time passes, the slider 26b will return to an initial position, and the press of the electric wire 5 by the roller member 27 will be cancelled | released.

  The coloring unit 30 includes a unit main body 31 and a plurality of ejection units 32. The unit main body 31 is fixed to the frame 11. The unit main body 31 supports a plurality of ejection units 32.

  As shown in FIG. 1, the plurality of ejection units 32 are provided side by side along the movement direction P of the electric wire 5, and 12 are provided in the illustrated example. The ejection unit 32 is provided on the side of the slack absorption unit 20 on the delivery roll 13 side, and is provided between the slack absorption unit 20 and the delivery roll 13. That is, the ejection unit 32 is provided downstream of the slack absorbing unit 20 in the movement direction P of the electric wire 5 and is provided upstream of the movement direction P of the electric wire 5 from the delivery roll 13.

  The plurality of ejection units 32 eject colorants of different colors toward the outer surface 5 a of the electric wire 5. Thereby, the electric wire 5 having more colored patterns can be manufactured. However, these ejection units 32 do not necessarily have to eject different colorants. Since the plurality of ejection units 32 have substantially the same structure, a single ejection unit 32 (hereinafter referred to as a first ejection unit 32A) will be described below as a representative.

  As shown in FIG. 3, the first ejection unit 32A includes a first nozzle 33A, a first valve 34A, and a first coloring material supply source 35A. The first nozzle 33 </ b> A is opposed to the outer surface 5 a of the electric wire 5. The first nozzle 33A has a hole through which a coloring material can pass. The hole extends linearly toward the outer surface 5 a of the electric wire 5. A colorant is supplied into the hole from the first colorant supply source 35A. The first colorant supply source 35A accommodates the color A colorant. The opening of the hole is opposed to the outer surface 5a of the electric wire 5, and allows the coloring material to pass through the inside.

  The first valve 34A is provided between the first nozzle 33A and the first coloring material supply source 35A, and is connected to these. Further, a pressurized gas supply source 36 is further connected to the first colorant supply source 35A. The pressurized gas supply source 36 supplies the pressurized gas into the first colorant supply source 35A. The pressurized gas supply source 36 is also connected to the colorant supply sources 35B to 35L of other ejection units 32 (hereinafter referred to as second to twelfth ejection units 32B to 32L), and is pressurized. The supplied gas is supplied into the coloring material supply sources 35B to 35L.

  When the first valve 34A is opened, the colorant in the hole of the first nozzle 33A passes through the opening described above by the pressurized gas supplied from the pressurized gas supply source 36, and the outer surface of the electric wire 5 It spouts toward 5a. Further, when the first valve 34A is closed, the ejection of the coloring material in the first nozzle 33A stops.

  In the first ejection unit 32A having the above-described configuration, the first valve 34A is opened for a predetermined time by a signal from a first valve drive circuit 47A, which will be described later, of the control device 40, and a certain amount of coloring material is supplied. It ejects toward the outer surface 5a of the electric wire 5. Thus, the first ejection unit 32A sprays the coloring material by a certain amount. Note that the droplet ejection indicates that the liquid coloring material is urged and ejected from the first nozzle 33A toward the outer surface 5a of the electric wire 5 in a droplet state, that is, in a droplet state.

  Similar to the first ejection unit 32A described above, the second to twelfth ejection units 32B to 32L also have a certain amount according to signals from corresponding second to twelfth valve drive circuits 47B to 47L, which will be described later. The coloring material can be ejected toward the outer surface 5 a of the electric wire 5. In this way, the first to twelfth ejection units 32 </ b> A to 32 </ b> L eject the coloring material toward the outer surface 5 a of the electric wire 5 to color the outer surface 5 a of the electric wire 5.

  The colorant mentioned above is a liquid substance in which a colorant (industrial organic substance) is dissolved and dispersed in a solvent. Examples of the color material 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 5a of the electric wire 5, the dye soaks into the covering portion 52, and when the paint adheres to the outer surface 5a of the electric wire 5, the pigment adheres to the outer surface 5a without penetrating into the covering portion 52. To do. Further, it is desirable that the solvent and the dispersion liquid have an affinity for the synthetic resin constituting the covering portion 52. In this case, the dye surely soaks into the covering portion 52, or the pigment adheres securely to the outer surface 5a of the electric wire 5.

  That is, the ejection unit 32 dyes a part of the outer surface 5 a of the electric wire 5 with a dye, or applies a pigment to the outer surface 5 a of the electric wire 5. For this reason, coloring the outer surface 5a of the electric wire 5 means dyeing (dying) a part of the outer surface 5a of the electric wire 5 and applying a pigment to a part of the outer surface 5a of the electric wire 5. Show.

  As shown in FIG. 1, the duct 15 is provided on the delivery roll 13 side of the ejection unit 32, and is provided between the ejection unit 32 and the delivery roll 13. That is, the duct 15 is provided downstream of the ejection unit 32 in the moving direction P of the electric wire 5, and is provided upstream of the sending roll 13 in the moving direction P of the electric wire 5. The duct 15 is formed in a cylindrical shape and allows the electric wire 5 to pass inside. A suction means (not shown) such as a vacuum pump is connected to the duct 15. The suction means sucks the gas in the duct 15 and prevents the solvent, the dispersion liquid, and the like in the coloring material from flowing out to the outside.

  The encoder 16 includes a pair of rotors 16a. The rotor 16 a is provided on the downstream side in the moving direction P of the electric wire 5 from the delivery roll 13. The rotor 16a is rotatable around the axis. The outer peripheral surface of the rotor 16 a is in contact with the outer surface 5 a of the electric wire 5 sandwiched between the pair of delivery rolls 13. The pair of rotors 16a sandwich the electric wire 5 between them. The rotor 16a rotates when the electric wire 5 moves along the arrow P. The rotational speed of the rotor 16a is proportional to the moving distance of the electric wire 5 along the arrow P.

  As shown in FIG. 4, the encoder 16 is connected to a pulse counting circuit 42 described later of the control device 40. The encoder 16 outputs a pulse signal toward the control device 40 when the rotor 16a rotates by a predetermined angle. That is, the encoder 16 detects the moving distance of the electric wire 5 along the arrow P and outputs information corresponding to the moving distance to the pulse counting circuit 42. In this embodiment, although the electric wire 5 is cut | disconnected by predetermined length, let the pulse signal output when the moving distance of the electric wire 5 reaches this predetermined length be B1. Normally, the encoder outputs a pulse signal corresponding to the amount of movement of the electric wire 5 due to friction between the electric wire 5 and the encoder mounting roll (rotor). However, if the amount of movement of the electric wire 5 and the number of pulses do not necessarily match depending on the state of the outer surface 5a of the electric wire 5, the movement distance information may be obtained at another location, the information may be fed back, and a comparison operation may be performed.

  As shown in FIG. 1, the cutting mechanism 17 is disposed downstream of the pair of rotors 16 a of the encoder 16 in the moving direction P of the electric wire 5. The cutting mechanism 17 includes a pair of cutting blades 17a. The pair of cutting blades 17a are arranged along the vertical direction. The pair of cutting blades 17a approach or separate from each other along the vertical direction. When the pair of cutting blades 17a come close to each other, the pair of cutting blades 17a cuts the electric wires 5 sent out by the pair of sending rolls 13 between each other. When the pair of cutting blades 17a are separated from each other, of course, they are separated from the electric wire 5.

  As shown in FIG. 4, the control device 40 includes a box-shaped device main body 41, a pulse counting circuit 42, a control circuit 43 as a control means, a delivery roll drive circuit 44, a linear guide drive circuit 45, a valve A selection circuit 46 and first to twelfth valve drive circuits 47A to 47L (only part of which are shown in FIG. 4) are provided. The apparatus main body 41 accommodates therein a pulse counting circuit 42, a control circuit 43, a delivery roll drive circuit 44, a linear guide drive circuit 45, a valve selection circuit 46, valve drive circuits 47A to 47L, and the like.

  The pulse counting circuit 42 counts the pulse signal input from the encoder 16 described above. The pulse counting circuit 42 is connected to the control circuit 43, and outputs information indicating what number pulse signal is currently input from the encoder 16 toward the control circuit 43. In the pulse counting circuit 42, the pulse signal generated by the very high frequency encoder 16 may be divided and put into the pulse counting circuit 42 in order to increase the pulse resolution.

  The control circuit 43 is connected to the feed roll drive circuit 44 and the linear guide drive circuit 45. The control device 40 controls the operation of the delivery roll 13. When the pulse signal is input from the encoder 16 (that is, according to the moving distance of the electric wire 5), the control circuit 43 determines whether or not to move the electric wire 5 by rotating the output roll 13 to the output roll driving circuit 44. And the electric wire 5 is intermittently moved to the delivery roll 13 according to a predetermined pattern. Then, as shown in FIG. 5, the control circuit 43 outputs a transmission start signal A and a transmission stop signal B to the transmission roll drive circuit 44.

  The delivery start signal A causes the delivery roll drive circuit 44 to rotate the delivery roll 13 and move the electric wire 5. The transmission start signal A is output at a predetermined timing (for example, a predetermined time after the transmission stop signal B is output). The sending stop signal B causes the sending roll drive circuit 44 to stop the rotation of the sending roll 13 and stop the electric wire 5. The transmission stop signal B is output when it is determined that the electric wire 5 having a predetermined length has been transmitted and the pulse signal B1 described above is input from the encoder 16.

  Further, the control circuit 43 controls the operation of the linear guide 26. When the pulse signal is input from the encoder 16 (that is, according to the moving distance of the electric wire 5), the control circuit 43 moves the slider 26b to the linear guide driving circuit 45 and presses the electric wire 5 against the roller member 27. Judgment is made. Then, the control circuit 43 outputs an approach start signal C, an approach stop signal D, a separation start signal E, and a separation stop signal F to the linear guide drive circuit 45 as shown in FIG.

  The approach start signal C causes the linear guide driving circuit 45 to move the slider 26b downward along the vertical direction and cause the roller member 27 to press the electric wire 5. The approach start signal C is output when a pulse signal C1 having a predetermined order is input. This pulse signal C1 is of the order ahead of the above-described pulse signal B1 among the pulse signals output when the electric wire 5 moves the predetermined length. Accordingly, the approach start signal C is output before the transmission stop signal B, and is output before the time t3 when the electric wire 5 starts to stop.

  The approach stop signal D causes the linear guide drive circuit 45 to stop the slider 26b from moving downward along the vertical direction. The approach stop signal D is output after time t4 when the electric wire 5 is stopped, which is determined by the encoder 16 or the like. That is, the approach stop signal D is output after the transmission stop signal B and is output after the electric wire 5 is stopped.

  The separation start signal E causes the linear guide drive circuit 45 to move the slider 26 b of the linear guide 26 upward along the vertical direction, thereby moving the roller member 27 away from the electric wire 5. The separation start signal E is output simultaneously with the transmission start signal A. The separation start signal E may be output after the transmission start signal A.

  The separation stop signal F causes the linear guide drive circuit 45 to stop the slider 26b from moving upward along the vertical direction. The separation stop signal F is output after a predetermined time from the output of the separation start signal E (transmission start signal A). For example, the separation stop signal F is output after the predetermined time described above by a timer. In the present embodiment, the predetermined time is before the time t2 when the electric wire 5 starts moving at a constant speed, but it may be after the time t2.

  The control circuit 43 configured as described above outputs these signals C, B, and D in the order of the approach start signal C, the transmission stop signal B, and the approach stop signal D before and after the electric wire 5 is stopped. Then, the control circuit 43 causes the roller member 27 to press the electric wire 5 from before the time t3 when the electric wire 5 starts to stop until after the time t4 when the electric wire 5 stops. In this way, the control circuit 43 outputs the transmission stop signal B according to the movement distance of the electric wire 5 detected by the encoder 16 and stops the electric wire 5 on the output roll 13 until a predetermined time until the electric wire 5 is supplied to the roller member 27. Press. “After a certain time” described in claims 1 and 8 of the claims means after the time t4 when the electric wire 5 stops.

  Further, the control circuit 43 having the above-described configuration outputs these signals A, E, and F in the order of the transmission start signal A, the separation start signal E, and the separation stop signal F before and after the movement start of the electric wire 5. The control circuit 43 causes the roller member 27 to press the electric wire 5 when the electric wire 5 is stopped. Then, the control circuit 43 causes the roller member 27 to press the electric wire 5 from before the time t1 when the electric wire 5 starts to move until after the electric wire 5 starts moving. In this way, the control circuit 43 outputs the sending start signal A according to the moving distance of the electric wire 5 detected by the encoder 16 and moves the electric wire 5 to the roller member 27 from just before moving the electric wire 5 to the sending roll 13 until a certain time later. Press. “After a certain time” described in claims 2 and 9 of the claims means after the time t1 when the electric wire 5 starts to move.

  As shown in FIG. 4, the delivery roll drive circuit 44 is connected to the delivery roll 13 via an interface (not shown). When the sending start signal A and the sending stop signal B are input from the control circuit 43, the sending roll drive circuit 44 outputs these signals A and B to the sending roll 13 to rotate or stop the sending roll 13. I will let you.

  The linear guide drive circuit 45 is connected to the drive unit 29 via an interface (not shown). When the approach start signal C or the approach stop signal D is input from the control circuit 43, the linear guide drive circuit 45 outputs these signals C and D toward the drive unit 29 so that the slider 26b approaches the electric wire 5. Or move this to stop. Further, when the separation start signal E or the separation stop signal F is input from the control circuit 43, the linear guide drive circuit 45 outputs these signals E and F toward the drive unit 29, and the slider 26 b is connected from the electric wire 5. Move away or stop this movement.

  The valve selection circuit 46 and the first to twelfth valve drive circuits 47A to 47L control the ejection units 32A to 32L described above. The valve selection circuit 46 is connected to the pulse counting circuit 42 and is connected to each of the valve drive circuits 47A to 47L. The valve selection circuit 46 outputs a signal that causes the valve drive circuits 47A to 47L to open the valves 34A to 34L when pulse signals in a predetermined order are input. The valve selection circuit 46 outputs signals that cause the valve drive circuits 47A to 47L to open the valves 34A to 34L according to the pattern of the mark 6 formed on the outer surface 5a of the electric wire 5.

  That is, the valve selection circuit 46 stores whether each of the valves 34A to 34L is opened or kept closed for each pulse signal input from the encoder 16, and the stored pattern The valve drive circuits 47A to 47L are controlled according to the above. However, when the pulse counting circuit 42 and the valve drive circuits 47A to 47L are directly connected, the valve selection circuit 46 can be omitted.

  Thus, the valve selection circuit 46 stores in advance a pattern for coloring the outer surface 5 a of the electric wire 5. Further, the valve selection circuit 46 directs the coloring material toward the outer surface 5a of the electric wire 5 by a predetermined amount in each of the ejection units 32A to 32L according to the stored pattern according to the moving distance of the electric wire 5 input from the encoder 16. Can be ejected.

  The first to twelfth valve drive circuits 47A to 47L are provided in the same number as the first to twelfth ejection units 32A to 32L, and correspond to the ejection units 32A to 32L, respectively. The valve drive circuits 47A to 47L are connected to the valves 34A to 34L of the corresponding ejection units 32A to 32L via an interface (not shown). When a signal for opening the corresponding valves 34A to 34L is input from the valve selection circuit 46, the valve drive circuits 47A to 47L output the signals toward the valves 34A to 34L. When the valve drive circuits 47A to 47L output signals for opening the corresponding valves 34A to 34L toward the valves 34A to 34L, the corresponding valves 34A to 34L are opened. Thus, the valve drive circuits 47A to 47L control the opening and closing of the corresponding valves 34A to 34L by outputting the aforementioned signals toward the corresponding valves 34A to 34L.

  In the slack absorbing device 1 having the above-described configuration, the outer surface 5a of the long electric wire 5 is colored, the electric wire 5 is cut into a predetermined length, and the electric wire 5 is moved intermittently along the longitudinal direction. In order to absorb the slack of the electric wire 5 at the time, first, the guide roll 12 is attached to the frame 11. The pair of cutting blades 17 a are separated from each other, and the electric wire 5 wound around the guide roll 12 is passed through the correction unit 14, the slack absorbing unit 20, the coloring unit 30, and the duct 15 in this order and sandwiched between the pair of delivery rolls 13. . And nozzle 33A-33L of ejection unit 32A-32L is attached to a predetermined location, and coloring material supply source 35A-35L corresponding to each nozzle 33A-33L is connected. Further, the pressurized gas supply source 36 is connected to the colorant supply sources 35A to 35L, and the gas in the duct 15 is sucked by the suction means.

  Then, the delivery roll 13 is driven to rotate, the electric wire 5 is pulled from the guide roll 12 and moved along the longitudinal direction of the electric wire 5, and the friction force of the first urging force Q <b> 1 is applied to the electric wire 5 by the correction unit 14. The electric wire 5 is stretched. Then, the roller member 27 is urged toward the electric wire 5 by the air cylinder 25 with the second urging force Q2.

  Then, when pulse signals in a predetermined order are input from the encoder 16 to the pulse counting circuit 42, the valves 34A to 34L corresponding to any of the valve drive circuits 47A to 47L are set for a predetermined time according to a predetermined pattern. Open a predetermined number of times. Then, any of the ejection units 32 </ b> A to 32 </ b> L ejects (drops) the coloring material toward the outer surface 5 a of the moving electric wire 5 by a certain amount. For example, when the valve drive circuit 47A opens the valve 34A once for a predetermined time, a mark 6 shown in FIG. 7 is formed on the outer surface 5a of the electric wire 5.

  And the solvent or dispersion liquid mentioned above evaporates from the coloring material adhering to the outer surface 5a of the electric wire 5, and dyes the outer surface 5a of the electric wire 5 with a dye, or applies a pigment to the outer surface 5a. The solvent or dispersion evaporated from the coloring material adhering to the outer surface 5 a of the electric wire 5 is sucked into the suction means from the duct 15. Thus, the outer surface 5a of the electric wire 5 is colored. In this embodiment, the outer surface 5a of the moving electric wire 5 is colored, but the outer surface 5a of the electric wire 5 in a stopped state may be colored.

  As shown in FIG. 6, when the pulse signal C1 is output from the encoder 16 immediately before the moving distance of the electric wire 5 reaches a predetermined length, the control circuit 43 of the control device 40 outputs an approach start signal C. The slider 26b, that is, the roller member 27 is moved downward along the vertical direction to press the electric wire 5, and then the output stop signal B is output to stop the output roll 13, that is, the electric wire 5, and finally the approach stop signal D is output. Then, the downward movement of the slider 26b, that is, the roller member 27 is stopped. The roller member 27 presses the electric wire 5 from just before the electric wire 5 stops until it stops, and absorbs the slack of the electric wire 5.

  Further, when the electric wire 5 is stopped, the telescopic rod 25b of the air cylinder 25 is extended, and the roller member 27 is always urged toward the electric wire 5 by the second urging force Q2, and a constant tension is applied to the electric wire 5. Thus, the slack of the electric wire 5 before and after the electric wire 5 is stopped is absorbed. Thereafter, the pair of cutting blades 17a approach each other, and the electric wire 5 is sandwiched between the cutting blades 17a and cut.

  When the electric wire 5 is stopped, the slider 26b is positioned downward and the telescopic rod 25b is extended so that the roller member 27 absorbs the slack of the electric wire 5 and applies a certain tension to the electric wire 5. When the stopped electric wire 5 is moved again, the control circuit 43 first outputs the delivery start signal A to start rotating the delivery roll 13 and outputs the separation start signal E to output the slider 26b, that is, the roller member. 27 is moved upward along the vertical direction to move away from the electric wire 5 (the roller member 27 also presses the electric wire 5 at this time). In this way, the slack of the electric wire 5 immediately after the movement starts immediately before the electric wire 5 moves is absorbed. Thereafter, the control circuit 43 outputs a separation stop signal F to stop the upward movement of the slider 26b, that is, the roller member 27, returns the slider 26b to the initial position, and releases the pressing of the electric wire 5 of the roller member 27. .

  According to this embodiment, the feeding roll 13 that moves the electric wire 5 along the longitudinal direction of the electric wire 5, the control circuit 43 that moves the electric wire 5 intermittently to the sending roll 13 according to a predetermined pattern, and the electric wire 5 Encoder 16 for detecting the moving distance of the electric wire 5 and a pressing portion 24 for pressing the electric wire 5 along the direction intersecting the moving direction P of the electric wire 5, and the control circuit 43 moves the electric wire 5 detected by the encoder 16. Depending on the distance, the wire 5 is pressed by the pressing portion 24 from just before the feeding roll 13 stops the wire 5 until a certain time later, so the wire 5 stops before the pressing portion 24 starts to loosen when the wire 5 stops. By pressing the electric wire 5 until after it is done, loosening of the electric wire 5 before and after the electric wire 5 is stopped can be reliably prevented.

  The control circuit 43 causes the pressing unit 24 to press the electric wire 5 from immediately before the electric wire 5 is moved again after the electric wire 5 is stopped by the sending roll 13 according to the moving distance of the electric wire 5 detected by the encoder 16 until a certain time later. Therefore, before the movement of the electric wire 5 starts, the pressing portion 24 presses the electric wire 5 from before the electric wire 5 starts to loosen until after the electric wire 5 moves, thereby reliably preventing the electric wire 5 from loosening before and after the electric wire 5 starts moving. be able to.

  The pressing portion 24 is provided rotatably with its outer peripheral surface in contact with the electric wire 5 and includes a roller member 27 that presses the electric wire 5 according to a command from the control circuit 43. By rotating the member 27, the frictional force between the electric wire 5 and the roller member 27 is alleviated, and the wear of parts at the contact portion with the electric wire 5 can be reduced.

  Since the brake unit for stopping the rotation of the roller member 27 is provided, the rotation of the roller member 27 due to its own inertia or the inertia of the electric wire 5 is stopped, and when the electric wire 5 is stopped by the roller member 27 in the stopped state, The electric wire 5 can be reliably pressed by pressing the electric wire 5 at the start of movement.

  Since the air cylinder 25 that constantly urges the roller member 27 toward the electric wire 5 is provided, a constant tension is always applied to the electric wire 5, and loosening of the electric wire 5 can be further reliably prevented. It is possible to prevent loosening of the moving electric wire 5.

  Since the coloring unit 30 for coloring the outer surface 5a of the electric wire 5 is provided, the outer surface 5a of the electric wire 5 can be colored without slack, and the electric wire 5 can be reliably colored in a predetermined pattern. The electric wires 5 can be reliably identified with each other.

  Since the cutting mechanism 17 that cuts (processes) the electric wire 5 is provided, the electric wire 5 is not loosened when the electric wire 5 is cut (processed), and the electric wire 5 can be reliably cut.

  In the present embodiment, the air cylinder 25 that always urges the roller member 27 toward the electric wire 5 is provided. However, the slackness of the electric wire 5 can be prevented without the air cylinder 25. Moreover, in this embodiment, although the brake part which stops rotation of the roller member 27 was provided, even if there is no brake part, the slack of the electric wire 5 can be prevented. However, in order to prevent loosening of the electric wire 5 more reliably, it is preferable that there is an air cylinder 25 or a brake part.

  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.
