  • the lower rotating wing 7 of the yarn traverse unit U8 located furthest from the turret plate 22 is partly inserted between the upper rotating wing 1 and the lower rotating wing 7 of the adjacent yarn traverse unit U7.
  • the interval between the upper rotating wing 1 and the lower rotating wing 7 in one traverse unit is configured to be almost the same as the thickness of the upper rotating wing 1 or the lower rotating wing 7.
  • the yarn traverse units U1 to U8 are composed of a group of yarn traverse units U1, U3, U5 and U7 located closer to the touch roller T and a group of the yarn traverse units U2, U4, U6 and U8 located further from the touch roller T than the first group.
  • the yarn traverse unit U1 located closest to the turret pleate 22 is closer to the touch roller T, while the yarn traverse unit U8 located furthest from the turret plate 22 is further from the touch roller T than the yarn traverse unit U1.
  • the rotation planes of the upper rotating wing 1 and the lower rotating wing 7 of each of the yarn traverse units U1 to U8 are all arranged in parallel with the rotation axis t1 of the touch roller T. Between the adjacent yarn traverse units U, the rotation plane of the upper rotating wing 1 or the lower rotating wing 7 of one of the yarn traverse units U is located between the rotation planes of the upper rotating wing 1 and the lower rotating wing 7 of the other yarn traverse unit U.
  • the rotation planes of the upper rotating wing 1 and the lower rotating wing 7 of the yarn traverse units U1 to U8 are all arranged in the four planes.
  • the rotating shafts 15 of the group of yarn traverse units U1, U3, U5 and U7 located closer to the touch roller T all have the same length, and the rotating shafts 15 of the group of the yarn traverse units U2, U4, U6 and U8 located further from the touch roller T also have the same length.
  • each rotating shaft 15 of the yarn traverse units U1, U3, U5 and U7 of the first group is longer than that of the yarn traverse units U2, U4, U6 and U8 of the second group.
  • This difference in length is equal to the difference in height between the first and second groups (for example, there is also a difference in distance from the lower rotating wing 7 to the rotation axis t1 of the touch roller T between the group of yarn traverse units U1, U3, U5 and U7 located closer to the touch roller T and the group of the yarn traverse units U2, U4, U6 and U8 located further from the touch roller T).
  • the pulleys 17 mounted on the upper ends of the rotating shafts 15 of the yarn traverse units U1 to U8 are all located at the same height.
  • 26 is a motor disposed in the elevating frame F and having a pulley 27 mounted on its output shaft 26a.
  • 28 is an endless belt as a driving belt extending from the pulley 27 mounted on the output shaft 26a of the motor 26 to the pulleys 17 mounted at the upper end of the rotating shafts 15 of the yarn traverse units U1 to U8.
  • 29 is an idler disposed opposite to each of the pulleys 17 of the yarn traverse units U1 to U8 across the endless belt 28 so as to press the belt 28 against the pulley 17.
  • 30 is a guiding pulley disposed so as to convert the travelling direction of the endless belt 28.
  • the yarn traverse units U1 to U8 can be concurrently driven by simply extending the single belt 28 among them.
  • each of the yarn traverse units U1 to U8 has the single pulley 17 driven by the endless belt 28 to rotate the upper rotating wing 1 and the lower rotating wing 7 of the yarn traverse units U1 to U8, thereby simplifying the structure compared to a structure in which the upper rotating wing and the lower rotating wing are individually rotated by two pulleys rotationally driven by an endless belt, as disclosed in the Published Japanease Translation of PCT International Publication for patent application (Tokuhyohei) No. 9-507824 (PCT/EP95/02674).
  • the rotation speeds of the pulleys that respectively drive the upper rotating wing and the lower rotating wing may differ due to the occurrence of slip between the pulley and the driving belt that drives the pulley, thereby hindering the yarn y from being normally transferred between the upper rotating wing and the lower rotating wing.
  • the single pulley 17 is driven by the endless belt 28 to rotate the upper rotating wing 1 and the lower rotating wing 7, the present invention prevents errors in the yarn y transfer caused by a difference in rotation speed between the two pulleys rotating the upper rotating wing and the lower rotating wing, respectively.
  • the rotation plane of the driving belt is located high in the direction in which the rotating wings are tilted upward and the height of the driving box (the elevating frame) that houses the driving belt become large.
  • the length of the rotating shafts of the yarn traverse units' pulleys gradually increases in the direction in which the rotating wing is tilted upward, and the rotating shaft of the pulley of the yarn traverse unit at the terminal is too long, resulting in a large load on the bearing for the rotating shaft.
  • the present invention precludes the height of the driving box from being large, and prevents the rotating shaft 15 of the pulley 17 from being too long.
  • the yarn y engages the upper rotating wing 1 or the lower rotating wing 7 and is then traversed. Subsequently, the yarn y contacts approximately one-fourth of the touch roller T located below the upper rotating wing 1 and the lower rotating wing 7, and is then wound around the package P contacting the touch roller T.
  • the length of the yarn y from the point at which it engages the upper rotating wing 1 or the lower rotating wing 7 to a contact point Ta on the touch roller T is called the "free length" Lf.
  • the yarn y is being transferred leftward while engaging with the lower rotating wing 7 as shown by the solid line in Figure 5, is transferred leftward in such a way as to follow the movement of the lower rotating wing 7 in a delayed manner, the yarn y is inclined between the engaging point 7d on the lower rotating wing 7 and the contact point Ta on the touch roller T. Subsequently, the yarn y contacts the touch roller T perpendicularly to the rotation axis t1 of the touch roller T and is then wound onto the package P.
  • a transfer point 7e on the lower rotating wing 7 is located to the left of the left end p1 of the package P, where the lower rotating wing 7 transfers the yarn y to the upper rotating wing 1.
  • the winding diameter D of the package P formed by the traversing operation by the upper rotating wing 1 and the lower rotating wing 7 located at the position shown by the dashed line tends to be larger than that of the package P formed by the traversing operation by the upper rotating wing 1 and the lower rotating wing 7 located at the position shown by the continuous line.
  • the free length Lf of each of the yarn traverse units U2, U4, U6 and U8 in the group arranged further from the touch roller T is longer than the free length Lf of each of the yarn traverse units U1, U3, U5 and U7 in the group arranged closer to the touch roller T.
  • the winding width W of the package P formed by the group of yarn traverse units U2, U4, U6 and U8 arranged further from the touch roller T tends to be smaller than that of the package P formed by the group of yarn traverse units U1, U3, U5 and U7 arranged closer to the touch roller T
  • the winding diameter D of the package P formed by the group of yarn traverse units U2, U4, U6 and U8 arranged further from the touch roller T tends to be larger than that of the package P formed by the group of yarn traverse units U1, U3, U5 and U7 arranged close to the touch roller T.
  • the yarn traverse unit U8 located furthest from the turret plate 22, that is, the yarn traverse unit U8 located at the tip of the bobbin holder 23, belongs to the group located further from the touch roller T and having a larger free length Lf than the group located closer to the touch roller T, thereby increasing the winding diameter D of the package P formed by the yarn traverse unit U8. This configuration ensures that this package P formed by the yarn traverse unit U8 will contact the touch roller T.
  • the yarn traverse unit U1 located closest to the turret plate 22, that is, the yarn traverse unit U1 located at the root of the bobbin holder 23 belongs to the group located further from the touch roller T and having a longer free length Lf than the group located closer to the touch roller T, then the winding diameter D of the package P formed by the yarn traverse unit U1 increases. This arrangement causes a force to press down the root of the bobbin holder 23, thereby further separating the tip of the bobbin holder 23 from the touch roller T.
  • the yarn traverse unit U1 located closest to the turret plate 22, that is, arranged at the root of the bobbin holder 23, belongs to the group located closer to the touch roller T and having a smaller free length Lf. This arrangement reduces the winding diameter D of the package P formed by the yarn traverse unit U1 located closest to the turret plate 22 and thus restrains the generation of a force that would press the bobbin holder 23 downward.
  • All yarn traverse units U are configured in the same structure, and in the yarn traverse units U2, U4, U6 and U8 in the group located further from the touch roller T, spacers S for height adjustments are inserted between a frame f1 of the elevating frame F and a driving box u1 in which transmission mechanisms such as the spur gears 12, 16, 18 and 20 of the yarn traverse unit U are accommodated.
  • these yarn traverse units U2, U4, U6 and U8 are located further from the touch roller T than the group of yarn traverse units U1, U3, U5 and U7 located closer to it.
  • the pulleys 17 of the adjacent yarn traverse units U are located at different heights. If the pulleys 17 are located at different heights, the driving belt (endless belt) 28 cannot be passed across all pulleys 17 when part of the width 17a of the pulley 17 that is contacted by the driving belt 28 is almost the same as the width 28a of the driving belt 28.
  • the width 17a of the pulley 17 is larger than the width 28a of the driving belt 28 by a value larger than or equal to the difference in height between the rotation planes of the upper rotating wing 1 of the adjacent yarn traverse units U, thereby allowing the driving belt 28 to be passed across both yarn traverse units U with the spacers S inserted therein and those without spacers S.
  • the endless belt 28 as a driving belt comprises a timing belt with teeth formed thereon and the pulley 17 mounted at the upper end of the rotating shaft 15 and rotationally driven by the belt also has teeth, slip can be prevented from occurring between the endless belt 28 and the toothed pulley 17, thereby ensuring the transfer of the yarn y to provide a yarn traverse device capable of stable traversing.
  • the endless belt 28 comprises a timing belt with teeth formed on both sides and because not only the pulley 17 mounted at the upper end of the shaft 15 but also the other pulleys 27, 29 and 30 have teeth, the transfer of the yarn y is further ensured, thereby ensuring that the yarn traverse device is capable of stable traversing.
  • the present invention has the following effects.
  • each yarn traverse unit can be independently operated without consideration for the driving timings of adjacent yarn traverse units.
  • the yarn traverse units are arranged horizontally and are not inclined, thereby eliminating the need to increase the height of the driving boxes for the yarn traverse units and the length of the rotating shafts with the pulleys mounted thereon. This configuration reduces the load on the shaft bearings and thus increases the lifetime expectancy of the bearings.
  • the yarn traverse device can be made more compact.
  • the rotation plane of the upper rotating wing or the lower rotating wing of one of the yarn traverse units is located between the rotation planes of the upper rotating wing and the lower rotating wing of the other yarn traverse unit, thereby helping to make the yarn traverse device even more compact.
  • the pulley in each yarn traverse unit is wider than the driving belt (endless belt) by a value larger than or equal to the difference in height between the rotation planes of the upper rotating wing of the adjacent yarn traverse units.
  • the yarn traverse units constituting the yarn traverse device have the same configuration, thus reducing the cost of the yarn traverse units U and thus the yarn traverse device.
  • the single driving belt drives all yarn traverse units, thereby ensuring the transfer of the yarn and providing a compact yarn traverse device having a simplified driving mechanism.
  • a cut in the belt can be easily detected by simply detecting the torque (load) on the motor driving the driving belt.
  • the yarn traverse device is adapted so that the rotation planes of the upper rotating wing and the lower rotating wing of each yarn traverse unit are all arranged in parallel with the rotation axis of the touch roller, and so that the rotation planes of the upper rotating wing and the lower rotating wing of adjacent yarn traverse units are arranged in four planes.
  • each yarn traverse unit can be independently operated without consideration for the driving timings of the adjacent yarn traverse units.
  • the yarn traverse unit located at the tip of the bobbin holder is placed further from the touch roller than the yarn traverse unit located at the root of the bobbin holder, thereby preventing the package formed by the yarn traverse unit located at the tip of the bobbin holder from leaving the touch roller.
  • the rotation plane of the upper rotating wing or the lower rotating wing of one of the yarn traverse units is located between the rotation planes of the upper rotating wing and the lower rotating wing of the other yarn traverse unit, thereby reducing the difference in the free length between the adjacent yarn traverse units.
  • the interval between the upper rotating wing and the lower rotating wing is approximately equal to the thickness of the rotating wing, thereby reducing the difference in the free length between the adjacent yarn traverse units to the degree that substantially no problem occurs.
