Abstract

An electric wire slack-absorbing apparatus and method are provided, by which an electric wire slack can be securely absorbed. The electric wire slack-absorbing apparatus includes a delivery roll, encoder, pressing part, and control device having a control circuit. The delivery roll transfers the electric wire along a longitudinal direction thereof. The encoder detects a transfer length of the electric wire. The pressing part presses the electric wire along a direction crossing a transferring direction of the electric wire. The control circuit makes the delivery roll intermittently transfer the electric wire according to a predetermined pattern. According to the transfer length of the electric wire detected by the encoder, the control circuit makes the pressing part press the electric wire from a time point just before the control circuit makes the delivery roll stop the electric wire to a time point when a predetermined time passes thereafter.

Description

APPARATUS ABSORBING ELECTRIC WIRE HANDLE AND METHOD TO ABSORB ELECTRIC WIRE CLEARANCE TECHNICAL FIELD The present invention relates to an apparatus that absorbs the play of an electric wire and method that absorbs the play of an electric wire to absorb a play of an electric wire which is intermittently transferred along a direction. Several electronic instruments are mounted on a motor vehicle as a mobile unit. Therefore, a motor vehicle is provided with a wiring harness to transmit electrical energy from a power source and control signals from a computer to electronic instruments. The wiring harness includes a plurality of electrical wires and connectors attached to ends of the electrical wires. The electric wire includes an electrically conductive central wire and a coating made of electrically insulating synthetic resin, which covers the central wire. The electrical wire is the so-called coated electrical wire. A connector includes a terminal fitting and a connector housing that receives the terminal fitting there. The terminal fitting, consisting of electrically conductive metal sheet or the like, is connected or attached to one end of the electric wire and electrically connected to the central wire of the electric wire. The connector housing is made of electrically insulating synthetic resin and is formed into a box. When the connector housing is connected to the electronic instruments, each electric wire is electrically connected to a corresponding electronic instrument through a terminal accessory, whereby the wiring harness transmits the electrical energy and desired signals to the electronic instruments. The electrical wire of the wiring harness must be distinguished in terms of a size of the core wire, coating material (in relation to the alteration in the materials depending on a property of heat resistance), and a purpose of use. The purpose of use means, for example, a purpose of use for a control signal for an airbag or an anti-lock braking system (ABS) and a purpose of use for a system of a motor vehicle, in which they are used electrical wires, as a power transmission system. Therefore, the outer surfaces of the electrical wires used in the wiring harness are colored with desirable colors to distinguish the purpose of use as described above.

When the wiring harness is mounted, first, an outer surface of a long electrical wire wound around a roll is colored with a desirable color and the electrical wire is cut to a predetermined length and then, a terminal fitting is placed at one end of the electric wire after removing the coating near the end. An electrical wire is connected to another electrical wire according to a need. Subsequently, the terminal accessory is inserted into the connector housing. In this way, the wiring harness is assembled. When the outer surface of the long electrical wire is colored and cut to a predetermined length, an electric wire cutting device is used (for example, see Patent Publication 1). The electric wire cutting device includes at least one frame as a device body (i.e. device body frame), a guide roller, a distribution roller, and a cutting mechanism. A coloring device is connected to the electric wire cutting device. The guide roller is rotatably supported on an end portion of the frame of the body of the device and winds a long electrical wire before being cut out around. The pair of distribution rollers is supported rotationally in a opposite extreme part of the frame of the body of the device. The pair of distribution rollers places the electric wire between them and pulls and transfers the electric wire along a longitudinal direction of the electric wire. The cutting mechanism is arranged on a downstream side of the distribution roller in a direction of transfer of the electric wire. The coloring device is arranged between the guide roller and the distribution roller. When the pair of distribution rollers rotates intermittently, the electric wire cutting device intermittently transfers an electric wire at a predetermined length. The external surface of the electric wire is colored by the coloring device while the electric wire is transferred. When the electric wire is stopped, the electric wire is cut by a cutting mechanism. In this way, if the electric wire is intermittently transferred, when the electric wire is stopped or when the stopped electric wire is transferred again, an electric wire clearance takes place due to the inertia of the electric wire. To absorb this slack of the electric wire, an apparatus that absorbs the slack of the electric wire is connected to the electric wire cutting device. The apparatus that absorbs the slack of the electric wire is arranged between the guide roller and the coloring device. The apparatus that absorbs the slack of the electric wire includes a pair of frames that support the guide rollers, a pair of guide rollers, and a frame that supports the transfer roller, a transfer roller, and an air cylinder. The pair of frames supporting the guide rollers is fixed to the frame of the body of the device and supports the respective guide rollers in a rotatable manner. The pair of guide rollers is arranged under the electric wire. The frame supporting the transfer roller is fixed to the frame of the device body and supports the transfer roller in a rotatable manner. The transfer roller is arranged on top of the electric wire and arranged between the pair of guide rollers along the direction of transfer of the electric wire. The air cylinder includes an air cylinder body and an expansion rod expandable from the body of the air cylinder. The body of an air cylinder is fixed to the support frame of the transfer roller and arranged on top of the electric wire. The expansion rod expands and contracts downwards (ie in a direction in which the expansion rod approaches the electric wire) of the air cylinder body. The transfer roller is connected to the expansion rod. When the pair of distribution rollers is stopped, in particular, a clearance of the electric wire that exists between the pair of guide rollers takes place due to the inertia of the electric wire. Then, the apparatus that absorbs the slack of the electric wire causes the expanding rod of the air cylinder to expand and contract to move the transfer roller downward, so that the apparatus that absorbs the slack of the electric wire pushes the electric wire along a direction crossing at right angles the direction of transfer of an electric wire to absorb the slack of the electric wire. Patent Publication 1: Japanese Patent Application Open to the Public No. 2004-134371 DESCRIPTION OF THE INVENTION PROBLEMS THAT THE INVENTION WILL RESOLVE However, in the apparatus that absorbs the slack of the electric wire described above, since the expansion rod of the air cylinder expands and contracts after the distribution rollers are stopped , so that the transfer roller is displaced downwards, therefore a gap of electric wire takes place, so that the electric wire behaves uncontrollably. When the outer surface of that electrical wire that has a play and behaves uncontrolled is colored, a resulting coloring pattern becomes disordered, ie, the resulting pattern of coloration is different from a predetermined pattern, causing a problem of that the discrimination of electrical wires becomes difficult. Therefore, an object of the present invention is to solve the above problems and provide an apparatus that absorbs the slack of an electric wire and a method that absorbs the slack of an electric wire, by which a clearance of an electric wire can be absorbed in a safe way.

MEANS FOR RESOLVING THE PROBLEMS To achieve the above objective, the present invention provides an apparatus that absorbs the play of an electrical wire to absorb the play of an electrical wire that is being intermittently transferred along a direction, which includes: Transfer means for transferring the electric wire along a longitudinal direction of the electric wire; control means that cause the transfer means to intermittently transfer the electric wire according to a predetermined pattern; detection means detecting a transfer length of the electric wire; and pressure means pressing the electric wire along an direction crossing a direction of transfer of the electric wire, where according to the transfer length of the electric wire detected by the detection means, the control means make the pressure means press the electric wire from a point in time just before the control means causes the transfer means to stop the electric wire at a point in time when a predetermined time passes subsequently. To achieve the above objective, the present invention also provides an apparatus that absorbs the slack of an electrical wire to absorb the play of an electrical wire that is being intermittently transferred along a direction that includes: transfer means that transfer the wire electrical along a longitudinal direction of the electric wire; control means that cause the transfer means to intermittently transfer the electric wire according to a predetermined pattern; detection means detecting a transfer length of the electric wire; and pressure means pressing the electric wire along a direction crossing in the direction of transfer of the electric wire, where according to the transfer length of the electric wire detected by the detection means, the control means make the pressure means press the electric wire from a point in time just before the control means causes the transfer means to transfer an electrical wire again after the control means causes the transfer means to stop the electrical wire at a point in time when a predetermined time passes later. As for the apparatus that absorbs the play of an electric wire described above above, according to the transfer length of the electric wire detected by the detection means, the control means causes the pressure means to press the electric wire from a point in time just before the means of control make the means of Transferring again the electric wire after the control means causes the transfer means to stop the electric wire to a point in time when a predetermined time passes later. The pressure means include a rotating roller member, an outer peripheral surface of which comes into contact with an electrical wire and which presses the electric wire in accordance with an order of the control means. The apparatus that absorbs the slack of the electric wire further includes a braking part which stops the rotation of the roller member. The apparatus that absorbs the slack of the electric wire further includes biasing means whenever it deviates the roller member toward the electrical wire. The apparatus that absorbs the slack of the electric wire also includes coloring means that color an external surface of the electric wire. To achieve the above objective, the present invention also provides a method that absorbs the slack of an electrical wire to absorb the play of an electrical wire that is being intermittently transferred along a direction that includes the pitch according to a length of transfer of electrical wire, of pressing the electric wire along a direction crossing a direction of transfer of the electric wire from a point in time just before the electric wire is stopped in time when a predetermined time passes later. To achieve the above objective, the present invention also provides a method that absorbs the play of an electrical wire to absorb the play of an electrical wire that is being intermittently transferred along a direction that includes the pitch in accordance with a transfer length of the electric wire, of pressing the electric wire along a direction crossing a direction of transfer of the electric wire from a point in time just before the electric wire is transferred again after the electric wire is stopped to a point in time when the predetermined time passes later.

EFFECTS OF THE INVENTION According to the present invention, since the control means causes the pressure means to press the electric wire from a point in time just before the electric wire is stopped until a point in time when a predetermined time passes later, that is, after stopping the electric wire, the pressure means press the electric wire from a point in time before the start of a slack of the electric wire takes place. up to a point in time after the electric wire is stopped, therefore, the slack of the electric wire before and after stopping the electric wire can be safely avoided. In accordance with the present invention, since the control means causes the pressure means to press the electric wire from a point in time just before the electric wire is transferred again after the electric wire is stopped to a point in the time when a predetermined time passes later, that is to say, after the beginning of the transfer of the electric wire, the pressure means press the electric wire from a point in time before the beginning of a slackness of the electric wire takes place. up to a point in time after the electric wire is transferred, therefore the slack of the electric wire before and after the start of the transfer of the electric wire is safely prevented from occurring. According to the present invention, since the control means causes the pressure means to press the electric wire from a point in time just before the electric wire stops to a point in time when a predetermined time passes subsequently, and since the control means make that the pressure means press the electric wire from a point in time just before the electric wire is transferred again after the electric wire is stopped at a point in time when a predetermined time passes subsequently, therefore it can Safely prevent a slack in the electric wire from occurring after stopping the electric wire and initiating the transfer of the electric wire. According to the present invention, since the pressure means include a rotating roller member, an outer peripheral surface which comes into contact with the electric wire and presses the electric wire in accordance with an order of the control means, that is, that the roller member rotates when the roller member presses the electric wire, therefore a friction between the electric wire and the roller member relaxes and therefore, the ablation of a part in contact with the wire electric can be reduced.

According to the present invention, since the apparatus that absorbs the slack of the electric wire further includes a braking part which stops the rotation of the roller member, hence the rotation of the roller member due to its own member inertia Roller or inertia of the electric wire can be removed and the roller member under that high condition can press the electric wire after stopping, the electric wire after starting the transfer of the electric wire, so that the electric wire can be pressed in a safe way. According to the present invention, since the apparatus absorbs the slack of the electric wire further includes deflection means which always deflect the roller member towards the electric wire, therefore a certain tension can always be applied to the electric wire so that a clearance of the electric wire can also be safely avoided, and a slackening of the electric wire during the transfer of the electric wire can also be prevented. According to the present invention, since the apparatus that absorbs the slack of the electric wire also includes coloring means that color an external surface of the electric wire, therefore an external surface of the electric wire that does not have Slack can be colored, so that an electrical wire can be colored securely according to a predetermined pattern and discrimination of the electric wires can be carried out. According to the present invention, since according to a transfer length of the electric wire, the electric wire is pressed along a direction crossing a transfer direction of the electric wire from a point in time just before the electric wire is stopped at a point in time when a predetermined time passes later, therefore, it can be safely avoided that a slackening of the electric wire occurs after stopping the electric wire. According to the present invention, since according to a transfer length of the electric wire, the electric wire is pressed along a direction crossing a transfer direction of the electric wire from a point in time just before the electric wire is transferred again after the electric wire is stopped at a point in time when a predetermined time passes later, therefore, it can be safely avoided that a slackness of the electric wire occurs after the start of the transfer of the wire. electric wire.

The central wire 51 is formed by twisting a plurality of elementary wires 51a together. Each elementary wire 51a is made of metal. The central wire 51 can be formed with a single elemental wire. The coating 52 is made of synthetic resin, for example, polyvinyl chloride. The coating 52 covers the central wire 51. That is, an outer surface of the coating 52 is an outer surface 5a of the electric wire 5. The coating 52 has a single color N (shown with white base color in Figure 7). A desired coloring agent can be mixed into the synthetic resin constituting the coating 52 so that the outer surface 5a of the electric wire 5 has a single color N or, alternatively, a color of the coating 52 itself can be a single color. N without mixing a coloring agent in the synthetic resin constituting the coating 52. In the latter case, the external surface 5a of the electric wire is called uncolored, that is, the coating 52 is called uncolored. In this way, "non-colored" means that a color of the external surface 5a of the electric wire 5 is a color of the synthetic resin itself constituting the coating 52 without mixing a coloring agent in the synthetic resin constituting the coating 52. When the outer surface 5a of the electric wire 5 is colored, for example, a marking 6 shown in the Figure 7 is formed on the entire outer surface 5a of the electric wire 5. A color of the mark 6 is the color A (indicated with diagonal and parallel lines in Figure 7). The color A is different from the individual color N. A shape of an array (ie a position on the electric wire 5) of the mark 6 are determined according to the predetermined pattern. The electric wire 5 is cut by a cutting mechanism 17 (explained below) in a predetermined length, then a plurality of electric wires 5 are grouped one conductor is attached to one end of each electric wire 5, so that a wiring harness is constructed. These connectors are coupled with coupling connectors of various electronic instruments and a motor vehicle, so that the wiring harness, ie the electrical wires 5 transmit various signals and electrical energy in the different electronic instruments. The electric wires 5 can be distinguished from each other by the change of color A of the mark 6 of several different colors. The color of the mark 6 becomes a sign to distinguish a type of wire or system. That is, a color of the mark 6 of the electric wire 5 is used for purposes of distinguishing use of the electrical wires 5 of the wiring harness. As illustrated in Figure 1, the gap absorbing apparatus 1 includes a frame 11, an apparatus body, a guide roller 12, a distribution roller 13 as the transfer means, a correction unit 14 as means for imparting tension , a slack absorbing unit 20, a coloring unit 30 as the coloring means, a duct 15, an encoder 16 as the detection means, a cutting mechanism 17 as the machining means, and a control device 40. The frame 11 is placed on the floor or similar of a plant. The frame 11 extends in a horizontal direction. The guide roller 12 is rotatably connected to an external part of the frame 11. The guide roller 12 winds the long electric wire 5 around it, on an external surface from which no mark is formed. The guide roller 12 provides the electric wire 5 to the correction unit 14, the gap-absorbing unit 20, the coloring unit 30, conduit 15, encoder 16 and the cutting mechanism 17 in turn. A pair of the distribution rollers 13 is provided on an opposite end portion of the frame 11. The pair of distribution rollers 13 is rotatably supported by the frame 11 and aligned along a vertical direction. The distribution rollers 13 rotate by means of a drive agent such as a motor (not shown in FIG. 1) in opposite directions to each other as the same number of revolutions. The distribution rollers 13 place the electric wire 5 between them and pull an electric wire 5 of the guide roller 12 along a longitudinal direction of the electric wire 5. The distribution rollers 13 transfer an electric wire 5 along a direction longitudinally of the electric wire 5 to transfer the electric wire 5 and a distribution unit (explained later) relatively to each other along the longitudinal direction of the electric wire 5. The distribution rollers 13 are linked to the control device 40 and repeat their rotation and stop according to an order of the control device 40, so that the distribution rollers 13 intermittently transfer the electric wire 5 along the longitudinal direction of the electric wire 5. The electric wire 5 is transferred from the guide roller 12 to the distribution rollers 13 along one direction indicated by an arrow P shown in Figure 1. The direction indicated by an arrow P is the transfer direction P of the electric wire 5. The correction unit 14 is provided in the distribution rollers 13 on one side of the guide roller 12, that is, provided between the guide roller 12 and the distribution roller 13. That is, the correction unit 14 is provided on a downstream side of the guide roller 12 in the transfer direction P of the electric wire 5. That is, that the correction unit 14 is provided on an upstream side of the distribution rollers 13 in the transfer direction P of the electric wire 5. The correction unit 14 includes a unitary body in the form of plate 14a, a plurality of first rollers 14b, and a plurality of second rows 14c. The unit body 14a is fixed to the frame 11. The first rollers 14b and the second rollers 14c are rotatably supported by a unitary body 14a. The plurality of first rollers 14b is aligned along the transfer direction P of the electric wire 5 and arranged on top of the electric wire 5. The plurality of second rollers 14c is aligned along the transfer direction P of the electric wire 5 and arranged under the wire . The first rollers 14b and the second rollers 14c are arranged in a zigzag pattern. The correction unit 14 places the electric wire 5 distributed from the guide roller 12 by the distribution rollers 13 between the first rollers 14b and the second rollers 14c. The correction unit 14 produces an electric wire 5 in straight form. The correction unit 14 imparts (ie gives) a frictional force to the electric wire 5 by placing the electric wire 5 between the first rollers 14b and the second rollers 14c. That is, the correction unit 14 imparts the frictional force of the first biasing force Q1 working in a direction reverse to the direction of traction (i.e. the direction of transfer of the electric wire 5) in which the rollers of distribution 13 pull the electric wire 5. The first biasing force Ql is weaker than the tensile force with which the distribution rollers 13 pull the electric wire 5. Therefore, the correction unit 14 imparts a function to along the longitudinal direction of the electric wire 5 to the electric wire 5 to stretch the electric wire 5. The slack-picking unit 20 absorbs a clearance of the electric wire 5 which is intermittently transferred along the P-direction.

Slackening absorber 20 is provided to the distribution rollers 13 on one side of the correction unit 1. The slack absorbing unit 20 is provided between the correction unit 14 and the distribution rollers 13. That is, the slack absorbing unit 20 is provided on the downstream side of the correction unit 14 in the transfer direction P of the electric wire 5. The slack absorbing unit 20 is provided on the upstream side of the distribution rollers 13 in the transfer direction P of the electric wire 5. As shown in Figure 2, the slack-picking unit 20 includes a pair of frames supporting the guide roller 21, a pair of guide rollers 22, a frame supporting the pressure part 23, and a pressure part 24 as the pressure means. The frames supporting the guide roller 21 are fixed to the frame 11. Each frame supporting the guide roller 21 is raised upwards from the frame 11. The pair of frames supporting the guide roller 21 are aligned along the direction of the guide. transfer P of the electric wire 5 having a distance between them. Each guide roller 22 is rotatably supported by the frame supporting the corresponding guide roller 21. The guide roller 22 is fixed under the electric wire 5 and an outer peripheral surface of each guide roller 22 comes into contact with the electric wire 5, so that the guide roller 22 guides an electric wire 5 preventing the electric wire 5 from leaving the transfer direction P of the electric wire 5. That is, the guide rollers 22 guide the transfer direction P of the electric wire 5. The frame supporting the pressure part 23 is fixed to the frame 11. The frame supporting the pressure part 23 rises upwards from the frame 11. The frame supporting the pressure part 23 is provided in the vicinity of the pair of frames supporting the guide roller 21. The pressure part 24 includes a linear guide 26, a drive part 29, a roller member 27, and a braking part (not shown in Figure 1). The linear guide 26 is attached to the frame supporting the pressure part 23. The linear guide 26 includes a rail 26a and a slide 26b. The rail 26a is fixed on the external surface of the frame supporting the pressure part 23. The rail 26a is formed in a straight form and is provided along the vertical direction. The slider 26b is movably supported by the rail 26a along a longitudinal direction of the rail 26a. Slider 26b is attached to an air cylinder 25 as diversion members. The air cylinder 25 includes a cylinder body 25a and an expansion rod 25b expandable from the cylinder body 25a. The cylinder body 25a is fixed to the slider 26b and arranged on top of the electric wire 5. The expansion rod 25b extends downwardly from the cylindrical body 25a along the vertical direction. That is, the expansion rod 25b extends from the cylinder body 25a in a direction in which the expansion roller 25b approaches the electric wire 5. A roller member 27 is attached to the cylinder expansion rod 25b of air 25. When pressurized gas is supplied to the cylinder body 25a, the air cylinder 25 deflects the expansion rod 25b, i.e., deviates the roller member 27 downwardly along a vertical direction with the second force of deviation Q2. In this way, the air cylinder 25 always deflects the roller member 27 towards the electric wire 5 with the second biasing force Q2. The second deflection force Q2 is weaker than the first deflection force Q1. The drive part 29 includes a motor 29a as a drive source, a screw body 29b, and a nut 29c. The motor 29a is fixed to the frame that it supports the pressure part 23. The body of the screw 29b is arranged along the vertical direction. The outer part of the screw body 29b is linked to an output shaft of the motor 29a, while the opposite end portion of the screw body 29b is supported by a support 29d fixed to the frame supporting the pressure part 23. In this way , the body of the screw 29b is supported by the frame supporting the pressure part 23 in a rotatable manner about an axis of the body. The nut 29c is screwed with the screw body 29b and fixed to the slider 26b. When a motor 29a of the driving part 29 acts, the output shaft of the motor 29a rotates to rotate the screw body 29b, the nut 29c moves along the vertical direction, and the slider 26b moves as far as possible. along a longitudinal direction of the rail 26a, that is, 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, so that the roller member 27 is connected to the expansion rod 25b of the air cylinder 25 moves along the vertical direction. In this way, the driving part 29 transfers the roller member 27 along the vertical direction.

The roller member 27 is rotatably supported by the expansion rod 25b of the air cylinder 25 and supported by the air cylinder 25 and the linear guide 26 movable along the vertical direction. The roller member 27 is arranged on top of the electric wire 5 and arranged in the center between the pair of guide rollers 22. The roller member 27 is supported movable along the vertical direction, so that the roller member 27 is supported mobile along the direction crossing at right angles (or crossed) the transfer direction P of the electric wire 5. When the driving part 29 transfers the slider 26b downwards along the vertical direction according to a In the order of the control circuit 43, the roller member 27 presses the electric wire 5, and an outer peripheral surface of the roller member 27 is provided rotatable by coming into contact with the outer surface 5a of the electric wire 5. The braking part stops the rotation of the roller member 27 and is, for example, a microgranule brake or known friction disk brake. The braking part acts in accordance with an order of the control circuit 43 after stopping or starting the transfer of the electric wire 5 to stop rotation of the roller member 27, causing the member of roller 27 securely presses the electric wire 5. A mechanism of the braking part can be mechanical or electromagnetic as long as the braking part stops the rotation of the roller member 27. When a pair of cutting blades 17a (explained later) the cutting mechanisms 17 approach each other and the electric wire 5 is once stopped to be cut, the electric wire 5 advances in the direction P due to its inertia and the electric wire 5 tends to have a clearance particularly between the pair of guide rollers 22. In the pressure part 24 of the slack-picking unit 20, the slider 26b moves downward, along the vertical direction from an initial position just below where the electric wire 5 it stops, so that the roller member 27 also moves down along the vertical direction (shown with alternating long dashed lines and two short lines in Figure 2), so that roller member 27 begins to press electrical wire 5 along the vertical direction. In addition, the roller member 27 presses the electric wire 5 along the vertical direction even after the electric wire 5 is stopped to absorb clearance from the electric wire 5. The vertical direction is a direction that intersects at right angles (which crosses) the address of transfer P of the electric wire 5. When the electric wire 5 is stopped, the expansion rod 25b of the air cylinder 25 extends to deflect the roller member 27 towards the electric wire 5 with the second biasing force Q2, imparting at both voltage specifies the electric wire 5. In this way, the slack absorbing unit 20 absorbs a clearance of the electric wire 5 and imparts the specific voltage to the electric wire 5 from a point in the fixed time before the electric wire 5 is stopped to a point in time after the electric wire 5 is stopped. The electric wire 5 tends to have a clearance due to its inertia even when the electric wire 5 once stopped is transferred again. The pressure part 24 of the slack absorbing unit 20 absorbs a clearance of the stopped electric wire 5 as described above and the air cylinder 25 imparts (ie, provides) the specific voltage to the electric wire 5. In the pressure part 24, the slider 26b begins to move upward along the vertical direction simultaneously when the electric wire 5 begins to be transferred and still at the moment when the roller member 27 is pressing the electric wire 5 along the vertical direction. In addition, the rod expansion 25b of the air cylinder 25 deflects the roller member 27 by the electric wire 5 with the second biasing force Q2 while the expansion rod 25b is contracting, to impart specific voltage to the electrical wire 5. When the electric wire 5 is transferred and a specific period of time passes, the slider 26b returns to an initial position thereof, so that the pressure to the electric wire 5 by the roller member 27 is released. The coloring unit 30 includes a unitary body 31 and a plurality of distribution units 32. The unitary body 31 is fixed to the frame 11 and supports the plurality of distribution units 32. As shown in Figure 1, the plurality of units distribution 32 is aligned along the transfer direction P of the electric wire 5. Twelve distribution units 32 are provided in the example shown in Figure 1. The distribution units 32 are provided on the distribution rollers 13 to a side of the slack absorbing unit 20. That is, the distribution units 32 are provided between the slack absorbing unit 20 and the distribution rollers 13. That is, the distribution units 32 are provided on the downstream side of the unit that absorbs slack 20 in the transfer direction P of the electric wire 5 and provided on the upstream side of the distribution rollers 13 in the transfer direction P of the electric wire 5. The plurality of distribution units 32 distributes respective coloring agents having different colors from each other towards the outer surface 5a of the electric wire 5. Therefore, electric wires 5 having various coloring patterns can be produced. However, the plurality of distribution units 32 may not distribute coloring agents having different colors from each other. Since the plurality of distribution units 32 have the same structure, in the following a distribution unit 32 (hereinafter, a first distribution unit 32A) will be explained as a representative unit. As shown in Figure 3, the first distribution unit 32A includes a first nozzle 33A, a first valve 34A, and a first colorant supply source 35A. The first nozzle 33A is oriented towards the outer surface 5a of the electric wire 5. The first nozzle 33A is provided with a hole to allow the coloring agent to pass therethrough. The orifice extends directly towards the external surface 5a of the electric wire 5. The agent dye is supplied to the orifice from the first coloring agent supply source 35A. The first coloring agent supply source 35A receives a coloring agent having a color A. An opening in the orifice faces the external surface 5a of the electric wire 5 and allows the coloring agent to pass inwardly. The first valve 34A is provided between the first nozzle 33A and the first colorant supply source 35A and connected to the first nozzle 33A and the first colorant supply source 35A. The first coloring agent supply source 35A is connected to a pressurized gas supply source 36. The pressurized gas supply source 36 supplies pressurized gas to the first coloring agent supply source 35A. The pressurized gas supply source 36 is also connected to the coloring agent supply source 35B-35L of other distribution units 32 (hereinafter, second to the twelfth distribution units 32B-32L) and supplies pressurized gas to the sources of coloring agent supply 35B-35L. When the first valve 34A is opened, the coloring agent existing within the orifice of the first nozzle 33A is distributed towards the surface 5a of the electric wire 5 passing through the opening of the orifice by the pressurized gas supplied from the pressurized gas supply source 36. When the first valve 34A is closed, the distribution of the coloring agent existing within the first nozzle 33A is stop The first valve 34A is opened for a predetermined period of time by a signal of a first valve actuation circuit 47A (explained below) of the control device 40, so that the first distribution unit 32A distributes a predetermined quantity of the coloring agent. towards the outer surface 5a of the electric wire 5. In this way, the first distribution unit 32A ejects a predetermined quantity of coloring agent each time towards the external surface 5a of the electric wire 5. Here, the "ejection" means that a coloring agent liquid in the form of a drop of liquid (or drops of liquid) is emitted vigorously from the first nozzle 33A to the outer surface 5a of the electric wire 5. In a manner similar to the first distribution unit 32A as described above, each of the second to the twelfth distribution units 32B - 32L distributes a predetermined amount of ag colorant to the external surface 5a of the wire by a signal from each of the second to the twelfth valve control circuits 47B-47L (explained later). In this way, each of the first to the twelfth distribution units 32A-32L distributes the coloring agent to the external surface 5a of the electric wire 5 to color the outer surface 5a of the electric wire 5. The coloring agent described above is a substance liquid, in which a coloring material (organic substance to be used in industry) is dissolved and dispersed in a solvent. The coloring material is a dye or a pigment (most of which are organic substances and synthetic substances). Sometimes, a dye is used as the pigment and the pigment is used as a dye. As an example, the coloring agent is a coloring liquid or coating material. The coloring liquid is a liquid, in which a dye in a solvent is dissolved or dispersed. The coating material is a material, in which a pigment is dispersed in the liquid dispersion. When the coloring liquid is added to the external surface 5a of the electric wire 5, the dye infiltrates the coating 52. When the coating material adheres to the external surface 5a of the electric wire 5, the pigment adheres to the outer surface 5a without infiltrating towards the coating 52. Preferably, the solvent and the liquid dispersion have an affinity for the synthetic resin constituting the coating 52 to safely infiltrate the dye into the coating 52 or to allow the pigment to adhere securely to the outer surface 5a of the electric wire 5. That is, the distribution unit 32 dyes a part of the outer surface 5a of the electric wire 5 with a dye or, alternatively, covers a part of the external surface 5a of the electric wire 5 with a pigment. In this specification, "coloring the outer surface 5a of the electric wire 3" means dyeing a portion of the outer surface 5a of the electric wire 5 with a dye or coating a portion of the outer surface 5a of the electric wire 5 with a pigment. As illustrated in Figure 1, the duct 15 is provided in the distribution roller 13 on one side of the distribution unit 32. That is, the duct 15 is provided between the distribution unit 32 and the distribution roller 13. That is, the conduit 15 is provided on a downstream side of the distribution unit 32 in the transfer direction P of electric wire 5 and on an upstream side of the distribution rollers 13 in the transfer direction P of the wire 5. The conduit 15 is formed in the form of a tube and allows the electric wire 5 to pass through it. The conduit 15 is connected to suction means (not shown in Figure 1) as a vacuum pump. The suction means sucks the existing gas in the conduit 15 to prevent the solvent and the liquid dispersion contained in the coloring agent from flowing outwards. The encoder 16 includes a pair of rotors 16a. The pair of rotors 16a is provided on the downstream side of the distribution rollers 13 in the transfer direction P of the electric wire 5. The rotor 16a rotates about its axis. An outer peripheral surface of the rotor 16a comes into contact with the external surface 5a of the electric wire 5 placed between the pair of distribution rollers 13. That is, the pair of rotors 16a places an electric wire 5 between them. When the electric wire 5 is transferred along the direction P, the rotors 16a rotate. The number of revolutions of the rotor 16 is proportional to the transfer length of the electric wire 5 along the P direction. As shown in Figure 4, the encoder 16 is connected in a pulse counter circuit 42 (explained below) of the control device 40. When the rotor 16a rotates at a predetermined angle each Once, the encoder 16 sends a pulse signal to the control device 40. That is, the encoder 16 detects a transfer length of the electric wire 5 along the P direction and sends data according to the transfer length detected to a pulse counter circuit 42. In the preferred embodiment, the electric wire 5 is cut to a predetermined length and the pulse signal, which is sent when the transfer length of the electric wire 5 reaches the predetermined length, is denoted by Bl here. Normally, the encoder sends a pulse signal according to a transfer length of the electric wire 5 by friction between the electric wire 5 and the encoder connecting roller (i.e. the rotor). However, in the case in which the transfer length of the electric wire 5 does not necessarily coincide with the number of pulses depending on a condition of the external surface 5a of the electric wire 5, the data of the transfer length of the electric wire 5 they can be obtained in a different place subject to feedback and computation data. As shown in Figure 1, the cutting mechanism 17 is provided to the downstream side of the pair of rotors 16a of the encoder 16 in the P direction. The cutting mechanism 17 includes a pair of cutting blades 17a. The pair of cutting blades 17a is aligned along the vertical direction. The cutting blades 17a approach and move away from each other along the vertical direction. When cutting blades 17a approach each other, the cutting blades 17a place an electric wire 5 provided by the distribution rollers 13 therebetween and cut the electric wire 5. When the cutting blades 17a move away from each other, the blades cut 17a leaves the electric wire 5. As shown in Figure 4, the control device 40 includes a body of the box-shaped device 41, the pulse counter circuit 42, the control circuit 43 as the control means, a driving circuit of the distribution rollers 44, a driving circuit of the guide lines 45, a valve selection circuit 46, and the first to the twelfth valve actuation circuits 47A -47L (only a part of which is shown). the same in Figure 4). The body of the device 41 contains a pulse counter circuit 42, the control circuit 43, the drive circuit of the distribution rollers 44, and the linear guide drive circuit 45, the valve selection circuit 46 and the first up the twelfth valve actuation circuit 47A - 47L in the.

The pulse counter circuit 42 counts the number of pulse signals fed from the encoder 16. The pulse counter circuit 42 is connected to the control circuit 43 and sends data, which indicates that the number of the pulse signals is fed from the encoder 16, to a control circuit 43. In the pulse counter circuit 42, to improve the resolution of the pulse, the generated pulse signals are divided with high frequency encoder 16 and fed to the pulse counter circuit 42. The circuit of control 43 is connected to the drive circuit of the distribution rollers 44 and the drive circuit of the linear guides 45. The control device 40 controls the action of the distribution rollers 13. When a pulse signal is supplied from the encoder 16 (i.e., according to a transfer distance of the electric wire 5), the control circuit 43 judges whether or not the Control circuit 43 causes the drive circuit of the distribution rollers 44 to rotate the distribution rollers 13 to transfer an electrical wire 5, so that the control circuit 43 causes the distribution rollers 13 to intermittently transfer the electrical wire 5 according to a predetermined pattern. Then, as shown in Figure 5, the circuit of control 43 sends a distribution start signal A and a distribution interruption signal B to the drive circuit of the distribution rollers 44. The distribution start signal A causes the drive circuit of the distribution rollers 44 to rotate to the distribution roller 13 so as to transfer the electric wire 5. The distribution initiation signal A is sent or produced to a predetermined point (for example, a point in time when a predetermined time passes after it is sent or produced the distribution interruption signal B). The distribution interruption signal B causes the driving circuit of the distribution rollers 44 to interrupt the rotation of the distribution rollers 13 to stop the electric wire 5. The distribution interruption signal B is produced or sent when an electric wire 5 of a predetermined length is judged to be proportionate and the pulse signal Bl is fed from the encoder 16. The control circuit 43 also controls the action of the linear guide 26. When a pulse signal is supplied from the encoder 16 (according to FIG. with a transfer distance of the electric wire 5), the control circuit 43 judges whether or not the control circuit 43 causes the driving circuit of the linear guide 45 move the slider 26b, so as to cause the roller member 27 to press the electric wire 5. Then, as shown in Fig. 5, the control circuit 43 produces or sends an approach start signal C, a signal of approach interruption D, an output start signal E and an output interruption signal F to the drive circuit of the linear guide 45. The approach start signal C causes the drive circuit of the linear guide 45 to move the slider 26b downwards, along the vertical direction to cause the roller member 27 to press the electric wire 5. The approach start signal C occurs when a pulse signal Cl of a predetermined order is fed. The order of the pulse signal Cl is first that the pulse signal Bl between the pulse signals to be sent when the electric wire 5 is transferred over a predetermined length thereof. Therefore, the approach start signal C is produced or sent before the interruption or distribution signal B and produced or sent before a point at time t3 when the electric wire 5 begins to be stopped. The approach interruption signal D causes the driving circuit of the linear guide 45 stop slider 26b so that it moves downward along a vertical direction. The approach interruption signal D is sent or produced after a point in time t when judged by the encoder 16 of the electric wire 5 stopped and so on. That is to say, that the approach interruption signal D is produced or sent after the distribution interruption signal B and after the electric wire 5 stops. The output start signal E causes the drive circuit of the linear guide 45 to move the slider 26b of the linear guide 26 upwards, along the vertical direction, so that part of the roller member 27 moves away from the electric wire 5. The start signal of output E is produced or sent simultaneously with the start signal of distribution A. The start signal of output E can be produced or sent after the start signal of distribution A. The signal of output interruption F causes the linear guide drive circuit 45 to stop slider 26b and its upward movement along the vertical direction. The output interrupt signal F is produced or sent after a predetermined time has elapsed and after the output start signal E (or the distribution start signal A) is sent or produced, for example, by a chronometer. In the preferred embodiment, the predetermined time is before the point in time t2 when the electric wire 5 begins to be transferred at a specific speed. However, instead, the predetermined time may be after the point in time t2. Before and after a point in time when the electric wire 5 is stopped, the control circuit 45 produces the approach start signal C, the distribution interruption signal B and the approach stop signal D in that sequence. Then, the control circuit 43 causes the roller member 27 to press the electric wire 5 from a point in time before the point t3 when the electric wire 5 begins to be stopped to a point in time after the point in the time t4 when the electric wire 5 is stopped. In this way, by sending the distribution interruption signal B according to the transfer length of the electric wire 5 detected by the encoder 16, the control circuit 43 causes the roller member 27 to press an electric wire 5 from a point in the time just before the control circuit 43 causes the distribution rollers 13 to stop the electric wire 5 to a point in time when a predetermined time passes later. Here, "to a point in the time when a predetermined time elapses subsequently "means" to a point in time after a point in time t4 when the electric wire 5 is stopped. "Before and after a point in time when the electric wire 5 begins to be transferred, the control circuit 43 sends the start signal of distribution A, the start signal of output E and the output stop signal F in that sequence.The control circuit 43 causes the roller member 27 to press the wire electrical 5 at a point in time when the electric wire 5 is stopped.Then, the control circuit 43 causes the roller member 27 to press an electrical wire 5 from a point in time before the point in time ti when the The electric wire 5 begins to be transferred to a point in time after a point in time when the electric wire 5 begins to be transferred, thereby producing or sending the signal A distribution start according to the transfer length of the electric wire 5 detected by the encoder 16, the control circuit 43 causes the roller member 27 to press the electric wire 5 from a point in time just before the control circuit 43 have the distribution rollers 13 transfer the electric wire 5 to a point in time when a predetermined time passes later. Here, "to a point in time when a predetermined time passes subsequently" means "to a point in time after the point in time ti when the electric wire 5 begins to be transferred". As shown in Figure 4, the drive circuit of the distribution rollers 44 is connected to the distribution rollers 13 through an interface (not shown in Figure 4). When the distribution start signal A or the distribution interruption signal B is supplied from the control circuit 43, the drive circuit of the distribution rollers 44 sends or produces the distribution start signal A or the interruption signal of distribution B towards the distribution rollers 13 for signaling or stopping the distribution rollers 13. The drive circuit of the linear guide 45 is connected to the drive part 29 through the interface (not shown in figure 4) . When the approach start signal C or the approach stop signal D is supplied from the control circuit 43, the drive circuit of the linear guide 45 sends the start signal approach C or the approach stop signal D towards the part of drive 29 to cause the slider 26b to move to approach the electric wire 5 or to cause the slider 26b to stop. When the output start signal E or the output interruption signal F is supplied from the control circuit 43, the drive circuit of the linear guide 45 sends the output start signal E or the output stop signal F towards the drive part 29 to cause the slider 26b to move out of the electric wire 5 or to cause the slider 26b to stop. The valve selection circuit 46 and a first up to the twelfth valve actuation circuit 47A-47L controls the distribution units 32A-32L. The valve selection circuit 46 is connected to the pulse counter circuit 42 and to the valve drive circuits 47A-47L. The valve selection circuit 46 sends signals to open the valves 34A-34L to the valve drive circuits 47A-47L when a pulse signal of a predetermined order is powered. That is, the valve selection circuit 46 sends signals to open the valves 34A-34L to the valve actuation circuits 47A-47L in accordance with a marking pattern 6 to be formed on the external surface 5a of the electric wire 5.

That is, which valve selection circuit 46 memorizes which valve valves 34A-34L should be opened and which valve valves 34A-34L should remain closed for each pulse signal fed from encoder 16 and controls the drive circuits Valve 47A - 47L according to a pattern so memorized. However, in the case where the pulse counter circuit 42 and the valve drive circuits 47A-47L are directly linked together, valve selection circuit 46 may be omitted. In this way, the valve selection circuit 46 memorizes in advance a coloring pattern of the outer surface 5a of the electric wire 5. The valve selection circuit 46 can cause the distribution units 32A-32L to distribute the coloring agent in a predetermined amount each time (i.e. by distribution) towards the outer surface 5a of the electric wire 5 according to the memorized pattern according to a transfer length of the electric wire 5 fed from the encoder 16. The first to the twelfth circuits valve actuation 47A - 47L correspond to the respective distribution units 32A - 32L. The first to the twelfth drive circuits of Valve 47A-47L are connected to the respective valves 34A-34L of the respective distribution units 32A-32L through interfaces (not shown in Figure 4). When the signals to open the respective valves 34A-34L are supplied from the valve selection circuit 46, the valve actuation circuits 47A-47L send the signal from each respective valve 34A-34L. When the valve actuation circuits 47A-47L send the signal of each respective valve 34A-34L to the valves 34A-34L, the valves 34A-34L are opened. In this way, the valve actuation circuits 47A-47L send the signal to the respective valves 34A-34L so that the valve actuation circuits 47A-47L control the opening and closing of the respective valves 34A-34L. When the outer surface 5a of the long electric wire 5 is colored and the electric wire 5 is cut to a predetermined length and a clearance of the electric wire 5 being intermittently transferred in the longitudinal direction thereof is first absorbed by the guide roller 12 is attached to the frame 12. The pair of cutting blades 17a are kept away from each other and the electric wire 5 entangled around the guide roller 12 is allowed to pass through the correction unit 14, the unit that absorbs the play , the coloring unit 30 and the duct 15 in turn is placed between the pair of distribution rollers 13. Then, the nozzles 33A-33L of the respective distribution units 32A-32L are placed in respective predetermined positions and the sources of coloring agent supply 35A-35L are connected to the respective nozzles 33A-33L. In addition, the pressurized gas supply source 36 is connected to coloring agent supply sources 35A-35L and the gas in the conduit 15 is sucked by the suction means. Then, the pair of drive rollers 13 is driven to rotate so as to pull the electrical wire 5 of the guide roller 12 and transfer the electric wire 5 along the longitudinal direction thereof, and the first biasing force Ql is imparted. to the electric wire 5 by the correction unit 14 to stretch the electric wire 5. Then, the roller member 27 is biased towards the electric wire 5 with the second biasing force Q2 by the air cylinder 25. Then, when a signal of pulse of a predetermined order is fed from the encoder 16 to the pulse counter circuit 42, according to a predetermined pattern, some of the valve drive circuits 47A-47L open the corresponding valves 34A-34L for a predetermined period of time a number predetermined times. Then, some of the distribution units 32A-32L distribute (eg, eject) a predetermined amount of coloring agent each time towards the outer surface 5a of the electric wire 5 being transferred. For example, when the valve actuation circuit 47A opens the valve 34A once for a predetermined period of time, a mark 6 shown in Figure 7 is formed on the external surface 5a of the electric wire 5. Then, the solvent dispersion or liquid is evaporated from the coloring agent adhered on the outer surface 5a and the electric wire 5, so that the outer surface 5a of the electric wire 5 is dyed with a dye and coated with a pigment. The solvent or evaporated liquid dispersion of the coloring agent adhered only to the external surface 5a of the electric wire 5 sucked by the suction means from inside the conduit 15. In this way, the external surface 5a of the electric wire 5 is colored. In a preferred embodiment described above, the external surface 5a of the electric wire 5 being transferred is colored. However, instead, the outer surface 5a of the electric wire 5 being stopped can be colored. As shown in Figure 6, when the signal Impulse Cl is sent from the encoder 16 just before a transfer length of the electric wire 5 reaches a predetermined length, the control circuit 43 of the control device 40 sends an approach start signal C to transfer the slide 26b to down along the vertical direction, that is, to transfer the roller member 27 downwards along the vertical direction to press the electric wire 5, then it sends a distribution interruption signal B to stop the distribution rollers 13, that is, to stop an electrical wire 5 and finally send an approach stop signal D to stop the downward movement of the slide 26b, that is, the downward movement of the roller member 27. The roller member 27 presses an electric wire 5 from a point in time just before the electric wire 5 is stopped at a point in the tie mpo after the electric wire 5 is stopped, thereby absorbing a clearance of the electric wire 5. Further, when the electric wire 5 is stopped, the expansion rod 25b of the air cylinder 25 extends to always bypass the limb member. roller 27 with the second biasing force Q2 towards the electric wire 5, thus imparting a tension predetermined to the electric wire 5. In this way, a clearance of the electric wire 5 before and after a point at the time of the arrest of the electric wire 5 is absorbed. Subsequently, the pair of cutting blades 17a approach each other and place the electric wire 5 between them and then cut the electric wire 5. When the electric wire 5 is stopped, the slide 26b is placed downwards and the wire Expansion 25b extends, so that the roller member 27 absorbs a clearance of the electric wire 5 and imparts a predetermined tension to the electric wire 5. When the electric wire 5 once stopped is transferred again, first, the control circuit 43 sends a distribution start signal A for starting the rotation of the distribution rollers 13 and sending an output start signal E to move the slide 26b, that is, to move the roller member 27 upwards along the direction vertical, thus departing from the slide 26b, i.e., the roller member 27 departing away from the electric wire 5 (still at this time, the roller member 27 press the electric wire 5). In this way, a clearance of the electric wire 5 from a point in time just before the electric wire 5 is transferred to a point in the fixed time after the electric wire 5 begins to be transferred is absorbed. Subsequently, the control circuit 43 sends an output interrupting signal F to stop the upward movement of the slide 26b, that is, to stop the upward movement of the roller member 27 to return the slide 26b to an initial position of the same, thereby releasing the pressure of the roller member 27 to the electric wire 5. In accordance with the preferred embodiment described above, an apparatus that absorbs the clearance of an electric wire 1 includes: the pair of distribution rollers 13 that transfer the electric wire 5 along the longitudinal direction of the electric wire 5; the control circuit 43 which causes the distribution roller pair 13 to intermittently transfer the electric wire 5 according to a predetermined pattern; the encoder 16 which detects a transfer length of the electric wire 5; and the pressure part 24 which presses the electric wire 5 along an direction crossing the transfer direction P of the electric wire 5, where according to the transfer length of the electric wire 5 detected by the encoder 16, the circuit control 43 causes the pressure part 24 to press the electric wire 5 from a point in time just before the control circuit 43 causes the distribution roller pair 13 stop the electric wire 5 to a point in time when a predetermined time passes later. Accordingly, the pressure part 24 presses the electric wire 5 from a point in time before a clearance of the electric wire 5 begins to take place until a point in time after the wire 5 is stopped, therefore the clearance of the electric wire 5 before and after a point at the time of the interruption of the electric wire 5 is safely prevented. Since according to a transfer length of the electric wire 5 detected by an encoder 16, the control circuit 43 causes the pressure part 24 to press the electric wire 5 from a point in time just before the control circuit 43 causes the distribution rollers 13 to transfer the electric wire 5 again after the electric circuit control 43 cause the distribution rollers 13 to stop the electric wire 5 to a point in time when a predetermined time elapses subsequently, i.e. s the start of the transfer of the electric wire 5, the pressure parts 24 press the electric wire 5 from a point in time before the slack of the electric wire 5 begins to take place until a point in time after that the electric wire 5 is transferred, and therefore a clearance of the electric wire 5 before and after a point at the time of the start of the transfer of the electric wire 5 is safely prevented. pressure 24 includes the rotating roller member 27, an outer peripheral surface that comes into contact with the electric wire 5 which presses the electric wire 5 in accordance with a control circuit order 43, that is, the roller member 27 rotates with the roller member 27 presses an electric wire 5, whereby a friction between the electric wire 5 and the roller member 27 relaxes and therefore, the ablation in the part in contact with the electric wire 5 can be reduced. that the apparatus that absorbs the slack of the electric wire 1 further includes the braking part which stops the rotation of the roller member 27, hence the rotation of the roller member 27 due to its own inertia of the roller member 27 or the inertia of the electric wire 5 can be removed and the roller member 27 under that interrupting condition can press the electric wire 5 after stopping the electric wire 5 and after starting the transfer of the electric wire 5, so that the electric wire 5 can be pressed from safe way. Since the apparatus that absorbs the slack of the electric wire 1 further includes an air cylinder 25 always deviates the roller member 27 towards the electric wire 5, therefore a certain voltage can always be applied to the electric wire 5 so that the Slack of the electric wire 5 can safely prevent a slackening of the electric wire 5 from occurring and a slackening of the electric wire 5 during the transfer of the electric wire 5 can be prevented since the apparatus that absorbs the slack of the electric wire 1 includes in addition the coloring means 30 that color an outer surface 5a of the electric wire 5, therefore an external surface 5a of the electric wire 5 also has clearance can be colored, so that the electric wire 5 can be colored in a safe way according to with a predetermined pattern and the discrimination of the electric wire 5 can be carried out safely. Since the apparatus that absorbs the slack of the electric wire 1 further includes the cutting mechanism 17 that cuts (ie machine) the electric wire 5, whereby no slackness of the electric wire 5 takes place when the electric wire 5 is cut off (ie machined) so that the cutting of the electric wire 5 can be carried out safely. In the preferred embodiment described above, an air cylinder 25 is provided to always bypass the roller member 27 toward the electric wire 5. Slack of the electric wire 5 without that air cylinder 25 can be prevented from occurring in the preferred embodiment described above. , a braking portion is provided to stop the rotation of the roller member 27. Slack of the electric wire 5 without that braking part can be prevented from occurring. However, in order to safely prevent a slackening of the electric wire 5 from occurring, the air cylinder 25 or the braking portion is preferably provided. The preferred embodiments mentioned above are described to aid in understanding the present invention and may be varied by one skilled in the art without departing from the spirit and scope of the present invention.
