Definitions

  • the present invention relates to yarn processing machines, such as air jet texturing machines and draw-texturing machines.
  • a conventional yarn processing machine 30 winding a plurality of yarns together into a single texturing yarn (in the illustrated example, the yarn processing machine winds two yarns into a doubled yarn.) or processing a doubled yarn is comprised of a plurality of yarn processing units arranged in rows, each unit including feed rollers 31, 34 (yarn feeding devices) that feed the yarn 4 forward, and a yarn texturing means 32, such as an air jet, a false twisting unit, etc.
  • the feed rollers 31, 34 are provided with line shafts 33a, 33b that are shared by all the units of the machine.
  • the line shafts 33a, 33b are each rotationally driven by a driving motor as a driving means (not shown in the drawing).
  • the feed rollers 31, 34 which rotate at different speeds, must be provided with separate line shafts 33a, 33b, respectively. Further, each of the plurality of line shafts must be arranged on a different axis, and staggered relative to the yarn feeding direction.
  • a further problem with the conventional yarn processing machine is that the yarn threading operation that must be performed prior to operation of the machine is difficult and time-consuming.
  • the feed rollers 31, 34, along with the rest of the machine parts, are spread out over a wide area, increasing the work-load of the operator, and further complicating the yarn threading operation.
  • the present invention is a yarn processing machine provided with multiple yarn paths along which yarns are processed, and provided with a plurality of yarn feeding devices along said yarn paths, wherein a separate yarn feeding device is provided for each yarn path, and wherein each of said yarn feeding devices is driven independently.
  • a separate yarn feeding device provided for each of the plurality of yarns provides independent driving for each individual yarn processing unit.
  • the plurality of yarn feeding devices provides for the plurality of yarns may be arranged in rows along the same axis.
  • the yarn feeding devices prefferably include driving rollers with driving motors, wherein the motor is arranged inside the roller, in order to make the device more compact.
  • Figure 1 is a planar view of a preferred embodiment of the yarn processing device of the present invention.
  • Figure 2 is a an enlarged cross-sectional view of the main parts of the yarn processing device of the present invention.
  • Figure 3 is a an enlarged view of the main parts of the machine of Figure 2.
  • Figure 4 is a cross-sectional view of the driving roller of Figure 3.
  • Figure 5 is an outline drawing of the yarn processing machine of the present invention.
  • Figure 6 is an outline drawing of a conventional yarn processing machine.
  • an air jet texturing machine 1 comprises a plurality of spindles (yarn processing units) 28 for simultaneously forming a yarn from a plurality of individual yarns.
  • a spindle 28 is a yarn processing unit that forms the yarn 29 to be processed by the yarn processing unit.
  • each spindle 28 draws a core yarn 4a and a effect yarn 4b from two yarn supply packages 2a, 2b stored in a creel stand 3, processes the yarns into a single texturing yarn, and then winds the yarn into a package, bobbin, or the like.
  • the spindle 28 is comprised of yarn feed rollers 8a, 9a for drawing the core yarn 4a from a supply package 2a, yarn feed rollers 8b, 9b for drawing the effect yarn 4b from a supply package 2b, yarn processing means 25 which textures the yarn using air, water, or the like, and winding means 26 which winds the processed yarn 29.
  • the yarn feed rollers 8a, 9a and 8b, 9b, 10 are sometimes referred to as "yarn delivering devices".
  • the air jet texturing machine 1 is comprised of a creel stand 3 that stores all of the supply packages 2a, 2b of the spindles 28, a winding stand 5 which draws unprocessed yarn 4 (the core yarn 4a and the effect yarn 4b) from the supply packages 2a, 2b, and textures and assembles them through air-jet processing into a single texturing yarn before winding them into packages, and an operator path 6 arranged between the creel stand 3 and the winding stand 5.
  • a ceiling frame 11 arranged above the operator path 6 serves as a bridge for the yarn between the creel stand 3 and the winding stand 5, and three spaced apart holding beams 12, 13, 14 are arranged in the ceiling frame 11, running in the direction of the operator path 6.
  • the first feed roller 8 is arranged independently in each yarn path 7 in the first holding beam 12 closest to the creel stand 3.
  • the second feed roller 9 is separately arranged in each yarn path 7 in the second holding beam 13, which is arranged on the winding stand 5 side, next to first holding beam 12.
  • Third feed roller 10 is similarly arranged separately in each yarn path 7 in the third holding beam 14, which is arranged adjacent to the winding stand 5.
  • a pin heater 15 that heats the unprocessed yarn 4 being delivered is arranged between the first feed roller 8 and the second feed roller 9.
  • the core yarn 4a and the effect yarn 4b drawn from the creel stand 3 is passed through the first feed roller 8 and the second feed roller 9 in each yarn path 7, and delivered to the yarn processing means 25.
  • Each feed roller 8, 9, 19 is arranged independently, and is independently driven.
  • each individual roller 8, 9, 19 is driven by a control device not shown in the drawings, and can be stopped, or have its speed controlled independently. Thus, if there is a yarn breakage or other problem, only the spindle 28 in which the problem occurred need be stopped or adjusted.
  • each of the feed rollers 8, 9, 10 shares basically the same structure.
  • the first feed roller 8 is principally comprised of a driving roller 16 provided with an internal driving motor (not shown in the drawing), and attached to the holding beam 12, and a drive receiving roller 18 coupled to the first holding beam 12 via a lever 17, and rotated in contact with the driving roller 16.
  • a driving motor 20 of driving roller 16 is attached to the first holding beam 12 via a holding member 19, and the drive shaft 21 of the driving motor 20 is attached to the first roller member 22.
  • the first feed roller member 22 is a concave bracket-shaped member, and arranged so as to substantially cover the periphery of the driving motor 20. This arrangement of the driving motor 20 inside the driving roller 16 makes the driving roller 16 more compact.
  • the lever 17 is roughly V shaped.
  • One end of the lever 17 is connected to the lever holding member 23 such that the lever 17 is freely rotatable.
  • the lever holding member 23 is fixedly attached to the first holding beam 12.
  • a second roller member 18a which serves as the drive receiving roller 18 is arranged in roughly the middle of the lever 17, and freely rotates around a horizontal axis.
  • the second roller member 18a is arranged at the bottom of driving roller 16, in contact therewith.
  • a spring coil 24 is connected between the lever 17 and the lever holding member 23, applying elastic force, and pushing the drive receiving roller 18 against the driving roller 17 when the two are in contact.
  • elastic force operates to pull the drive receiving roller 18 away from the driving roller 16.
  • the processing means 25 and the winding means 26 are arranged in the winding stand 5.
  • the yarn 29 processed by the processing means 25 winds through the third feed roller 10 arranged above the processing means 25 before being fed to the winding means 26.
  • an operator 27 passes the yarn along each yarn path 7.
  • the unprocessed yarn 4 is threaded between the driving and drive-receiving rollers 16, 18 of the first feed roller 8 and the second feed roller 9, and then passed in order through the yarn processing means 25, the third feed roller 10, and led to the winding means 26.
  • first and second feed rollers 8, 9 are arranged along the same neighboring beams (first beam 12 and second beam 13) on all the yarn paths 7, the operator 27 can thread the unprocessed yarns 4 in the yarn feeding direction without hardly having to move. This enables all the yarns to be quickly and easily threaded in preparation for processing. Particularly since the feed rollers 8, 9, 10 are all within roughly the same arm's reach of the operator 27, threading the yarns through these rollers is very easy.
  • each of the feed rollers 8, 9, 10 rotate independently, feeding the unprocessed yarn 4 along the yarn paths 7.
  • the feed rollers 8b and 9b which feed along the effect yarn 4b to be assembled the core yarn 4a, rotate more quickly than the feed rollers 8a, 9a for the core yarn 4a, thereby passing the effect yarn 4b more quickly than the core yarn 4a.
  • the core yarn 4a and the effect yarn 4b are integrated at the processing means 25, textured, passed through the third feed roller 10, and then send to the winding means 26 where the integrated texturing yarn is wound.
  • each of the feed rollers 8, 9, 10 is driven independently, the feed rollers 8, 9, 10 can be freely arranged within the machine, the feed roller pairs 8a, 8b and 9a, 9b, operating at different speeds, can be arranged in the same line (along the same axis), and the rotary drive feeding the yarns of individual yarn paths 7 can be stopped. Further, the draw rate of the unprocessed yarns 4 of the individual yarn paths 7 can also be freely and independently changed.
  • the feed rollers 8, 9, 10 are each driven separately and independently, the feed rollers 8, 9, 10 can be independently driven for each individual spindle 28, allowing each spindle to be run independently of the others, a particularly useful feature in a yarn processing machine 1 where many spindles 28 are arranged side-by-side.
  • feed rollers 8, 9, 10 of different feed speeds for each yarn path 7 can be arranged in the same row, the entire yarn processing machine 1 can be made more compact, and yarn threading can be made significantly easier. Further, the yarn paths become easier to distinguish.
  • the feed rollers 8, 9, 10 are comprised of the driving roller 16 having an internal driving motor 20 attached to a respective holding beam 12, 13, 14, and a drive receiving roller 18 that is held in pressured contact with the driving roller 16 via lever 17 which is attached to a respective holding beam 12, 13, 14, the feed rollers 8, 9, 10 are more compact, and the yarn threading operation is easier to perform.
  • the driving motors of the feed rollers 8, 9, 10 may be controlled such that their speeds are adjusted independently of each other via a control device not shown in the drawings.
  • embodiments of the present invention need not be restricted to air-jet texturing machines, but may also include false-twisting machines, and false-twisting draw texturing machines, as well.
  • the present invention accomplishes the following:
