- FIG. 4 is a side view of the main part in FIG. 2.
- An embodiment of the present invention will hereby be explained with reference to the drawings.
- As shown on FIG. 1, a wire replacer with
length examiner 20 has pulley supports 22 and 23 fixed to abody 21 at its top and bottom. Respective one of the pulley supports 22 and 23 rotatably supports respective pair ofpulleys 25 fixed to itsrespective axle 24. Arespective pulley 25 at the top has aservo motor 26 with an axle in connection withaxle 24 thereof, theservo motor 26 to be driven for therespective pulley 25 to be rotated. The respective pair ofpulleys 25 at the top and bottom has arespective timing belt 27 applied therebetween, the timing belt being fixed to anozzle base 28. - The
nozzle base 28 has upstreamwire guide nozzles 29, or first guide, arranged vertically in rows. A respectiveupstream nozzle 29 is to be stopped selectively at a determined position on a pass-line L1 by movement of therespective timing belt 27. Therespective nozzle 29 has arespective hole 29 b for guiding a wire W1 to its inner part of its longitudinal direction. Therespective nozzle 29 has arespective cut 29 a for a roll, in whichfeed rolls 32 as described later is to come. Therespective nozzle 29 has a position P1 at its end downstream in a wire feed direction, the position P1 being set not to interfere with arotation drive mechanism 42 for thefeed rolls 32. The reason that the end position P1 is freely set is to be described later. - The
body 21 has one downstreamwire guide nozzle 30, thenozzle 30 being arranged at a predetermined distance upstream of theupstream nozzle 29 at a position on a predetermined pass-line L1. Thedownstream nozzle 30 is made of a flexible material, with ahole 30 b for guide of the wire W1 to its inner part of its longitudinal direction. Thedownstream nozzle 30 has aswing arm 31 fixed with its downstream end, with theswing arm 31 being rotatably supported by thebody 21. A rotation of thearm 31 makes thedownstream nozzle 30 flexibly deformed, and the wire W1 to be inserted in thedownstream nozzle 30 is moved at its end selectively to a termination manufacturing means, or a wire stripping part and a terminal crimping part, at its distal end. - As illustrated on FIG. 2 and3, a pair of
feed rolls 32 are arranged at both sides relative to theupstream nozzle 29 on the pass-line L1. Arespective feed roll 32 has a respective support 33 a supporting its center axle for rotation, therespective support 33 being fixed to a respective distal end of a pair ofarms 34. Arespective arm 34 has arespective axle 35 fixed at its proximal end. Therespective axle 35 is fixed with a respective one ofgears gears axle 35 is connected to adrive rod 41 a for anelectromagnetic solenoid 41 through alink 40. - When the
solenoid 41 drives therod 41 a to be lengthened, thelink 40 rotates in the direction shown by arrow al on FIG. 3. The rotation causes the pair ofarms 34 to be rotated in the direction shown by arrow b1 on FIG. 3. When the pair ofrolls 32 are moved apart from each other and thesolenoid 41 is driven to shorten therod 41 a, thelink 40 rotates in the direction shown by arrow cl on FIG. 3. The rotation causes the pair ofarms 34 to be rotated in the direction shown by dl on FIG. 3, thus to move the pair ofrolls 32 to come close each other. The movement causes the pair ofrolls 32 to be moved between a press-contact position and a detached position, the press-contact position for theupstream nozzle 29 to come in thecut 29 for press-contact with the wire W1, the detached position for theupstream nozzle 29 to come out of thecut 29 a to be away from the wire W1. - The pair of
rolls 32 are rotated by arotation drive mechanism 42. Thedrive mechanism 42 includes adrive motor 43 with arotation axle 43 a; afirst spur gear 44 fixed to therotation axle 43 a; second and third spur gears 45 and 46 engaged with each other, thesecond gear 45 being engaged with thefirst spur gear 44; fourth andfifth gears respective arm 34 and respectively engaged with respective one of the second and third spur gears 45 and 46; and sixth andseventh gears respective roll 32 and engaged with respective one of the fourth and fifth spur gears 47 and 48. - When rotating the
drive motor 43 in the direction of the arrow e1, the rotation is transmitted to thefirst gear 44, thesecond gear 45, and thefourth gear 47 in order and to thefirst gear 44,second gear 45,third gear 46, thefifth gear 48, and theseventh gear 50 in order, thus to rotate the pair ofrolls 32 in a direction of feeding the wire W1. - An
intermediate nozzle 51 is interposed between the upstream anddownstream nozzles nozzle 51 includes a fixednozzle 51 a; and amovable nozzle 51 b to move in an axis direction, overlapping partially with the fixednozzle 51 a. The fixednozzle 51 a is fixed by anozzle fixing member 53 fixed through acylinder mechanism 52. Themovable nozzle 51 b is connected to adrive rod 52 a of thecylinder mechanism 52, and the drive of thecylinder mechanism 52 causes themovable nozzle 51 b to be moved in the axis direction, varying an overlap amount with the fixednozzle 51 b. By the movement of themovable nozzle 51 b, theintermediate nozzle 51 is displaced between a guide position (a solid lined position on FIG. 4) and a non-guide position (an imaginary lined position), the guide position where themovable nozzle 51 b is to be brought substantially in contact with theupstream nozzle 29 of a downstream end and theintermediate nozzle 51 is to guide the wire W1 to thedownstream nozzle 30, the wire W1 to be guided from theupstream nozzle 29, the non-guide position where themovable nozzle 51 b is to be apart from the downstream end of theupstream nozzle 29 for opening a coming-in space for alength measurement roll 55 between theintermediate nozzle 51 and theupstream nozzle 29. - The
support plate 36 has anozzle holding member 54 with aguide hole 54 a fixed thereon, theguide hole 54 a for inserting themovable nozzle 51 b at its end to be moved. Themovable nozzle 51 b is guided at its end by the holdingmember 54 for movement. - A pair of length measurement roll (length examination roll)55 are arranged at both sides relative to the
intermediate nozzle 51 at a predetermined position on the pass-line L1. Arespective roll 55 is rotatably supported at its center axle by respective one of a pair ofmovement support members 56. Arespective support member 56 is supported by a respective drive rod (not shown on FIGS. ) of a pair ofsolenoid mechanisms 57. The pair ofsolenoid mechanisms 57 is fixed on thesupport plate 36. By a drive of the pair of thesolenoid mechanisms 57, the pair of measurement rolls 55 is displaced between a position for contact with the wire W1 in the open space and a position away from the wire W1. One of the measurement rolls 55 has anencoder 58 provided thereto to detect rotation of the one of the measurement rolls 55. Detection output of theencoder 58 causes a feed amount of the wire W1 to be measured. - Next, the
replacer 20 of operation is explained. At wire length examination, theintermediate nozzle 51 is placed at the non-guide position (the imaginary lined position on FIG. 4). Making use of the opening space defined by theintermediate nozzle 51, the pair of measurement rolls 32 are brought in contact with the wire W1 under pressure. In thecut 29 a of theupstream nozzle 29, the pair of feed rolls 32 is brought in contact with the wire W1 under pressure. When the wire W1 is fed, the pair of feed rolls 32 follows the wire to be rotated. With a detection output of theencoder 58 by the rotation, a feed amount of the wire W1 is measured. When the feed amount achieves at a desired value, the pair of feed rolls 32 is stopped in its rotation. At this point, at downstream of the wire W1 fed by the pair of feed rolls 32, the measurement rolls 55 rotate to measure feed amount, and the wire W1 is to be precisely measured. - On the other hand, with the
intermediate nozzle 51 established at a predetermined guide length, theupstream nozzles 29 are to be established at their downstream end positions P1 not to interfere with therotation drive mechanism 42 of the feed rolls 32, and theupstream nozzles 29 are to be moved. According to the above-mentioned, ensuring theupstream nozzles 29 in movement, the wire W1 is to be precisely measured. - When replacing by a wire with different color, diameter, or quality, the wire W1, being used at present, is pulled back at a predetermined position. The pair of feed rolls 32 and measurement rolls 55 are moves to the detached position, and the
upstream nozzle 29, corresponding to a wire W1 to be replaced, is moved at a position on the pass-line L1. Thereafter, theintermediate nozzle 51 is moved from the non-guide position to the guide position (the solid lined position on FIG. 4), and the pair of feed rolls 32 is moved at the press-contact position. Rotating the pair of the feed rolls 32, the wire W1 in theupstream nozzle 29 is fed. The fed wire W1 is guided in order by theupstream nozzle 29, theintermediate nozzle 51, and thedownstream nozzle 30 to be securely supplied to a nozzle end, and wire feed is as possible in automation as a conventional art, ensuring wire cut length in accuracy. - The
intermediate nozzle 51 includes the fixednozzle 51 a, and themovable nozzle 51 b to be moved in an axle direction, overlapping partially with the fixednozzle 51 a. Themovable nozzle 51 b varies an overlap amount with the fixednozzle 51 a to be moved between the guide position and the non-guide position. The fixednozzle 51 a guides themovable nozzle 51 b to be moved, and themovable nozzle 51 is to be stabilized in movement. - In addition, movement of the
movable nozzle 51 b is in a straight line, and is possible to be connected directly to thecylinder mechanism 52, so that the constitution to be extremely simplified. Themovable nozzle 51 b is guided by thenozzle holding member 54 between the guide position and the non-guide position for movement, and themovable nozzle 51 b is moved, being guided by thenozzle holding member 54, so that themovable nozzle 51 b is further stabilized in movement. - In the above-described embodiment, though the
movable nozzle 51 b is constituted integrally to move in a straight line, themovable nozzle 51 b may be constituted by two separated upper and lower members, which are to be moved together in the detached or contact direction by a parallel or rotation movement to be displaced between the guide and non-guide positions. The embodiment makes themovable nozzle 51 b further secure and stable in movement and a drive system further simpler. In addition, though the embodiment is constituted by the feed rolls 32 and the measurement rolls 55 as a pair, the other may be constituted as merely a fixed press receiving member. The constitutions of the feed rolls 32 and the measurement rolls 55 as a pair make wire feeding motion and length examination motion smooth and secure. - The entire contents of Japanese Patent Applications P2000-089617 (filed on Mar. 28, 2000) is incorporated herein by reference.
