Definitions

  • the present invention relates to a creel for twisting non-twist yarn and supplying the same to a predetermined machine such as a loom or a warper.
  • a twist yarn as a warp such as a safety belt or a sling
  • a beam is prepared by winding thereon a predetermined number of twist yarns before a weaving operation
  • a bobbin is formed by winding thereon a preliminarily prepared twist yarn and a plurality of the bobbins are arranged on a creel to be supplied to a loom as warps.
  • twist yarn is used for a weaving operation as a warp yarn. That is, it is necessary to vary a twist number in accordance with the use of a woven cloth and/or specific properties of the yarn so that the required feeling to the touch is obtained in the resultant cloth. Since a yarn twisting is not usually carried out by a weaver but is done by an outside twister, it is almost impossible to change a twist number after the yarn twisting has been completed, even if it has been found that the twist number is unsuitable for the desired cloth. Also, since it is not certain that the same length of twist yarn is wound on the respective bobbin, a waste of the twist yarn may be generated due to this difference of the yarn length between the bobbins.
  • a length of the twist yarn wound on a bobbin is at most one half, usually less than one third of that of a large packaged material yarn bobbin, a troublesome bobbin exchanging and yarn tying operation is necessary midway in the weaving process, and, in some uses, the resultant product may be inferior in the tied portion and cannot be used.
  • a cloth is woven while a twist yarn is used as a warp yarn, there are more inconveniences compared with a case when non-twist yarns are directly supplied to a loom from a creel.
  • the present inventors proposed in Japanese Patent Application No. 57-029084 a creel in which a plurality of bobbins are arranged, each carrying a non-twist yarn thereon and provided with a twisting device similar to a flyer mechanism, and the non-twist yarn is delivered from the bobbin and simultaneously twisted thereby.
  • this creel the non-twist yarn in a large packaged bobbin can be supplied to a loom while being twisted but there is a serious problem in that the installation cost is expensive.
  • a spindle driving means constituting a main part of the twisting mechanism is described as a combination of shaft and bevel gears, which is so complicated in structure that a reduction in the installation cost is prevented.
  • JP-A-53 069 555 shows a technical conception in that yarns snarled or yarn entangled can be prevented but does not show or suggest to use a yarn storage portion and a yarn adjusting ring so that the non-twisted yarn is effectively twisted.
  • the present invention is, therefore, not anticipated by D2.
  • JP-A-30 002 833 shows a technical conception in that yarn entanglement can be prevented when the yarn is withdrawn from a yarn bobbin by utilizing a resilient ring mounted on a tip and portion of a yarn bobbin and the yarn withdrawn from the bobbin passes through between the ring and a surface of the tip and portion of a yarn bobbin.
  • the yarn bobbin is stationary provided inside a shuttle and never be rotated so as to positively twist the yarn withdrawing from the yarn bobbin.
  • JP-A-30 002 833 fails to show or suggest the yarn twisting method as defined by the present invention in which the yarn storage portion and the yarn adjusting ring are provided on a tip end portion of the yarn bobbin.
  • twist yarns are supplied to a loom for weaving a cloth of a simple design, the abovesaid prior art can be satisfactorily applied.
  • a bobbin carrying a non-twist yarn and fixedly supported by a spindle rotates so that the yarn is unwound, in which a size of ballooning varies in accordance with a position at which the non-twist yarn is released from the bobbin.
  • a yarn length withdrawn from the bobbin also varies as the ballooning size changes.
  • a length of the wrapping yarn varies in accordance with the variation of the ballooning so that yarn withdrawal is controlled.
  • the yarn adjustment ring has functions for imparting substantially a constant tension to the withdrawn yarn as well as maintaining a constant twist number in the yarn, because the twist is imparted to the yarn after the yarn has passed the exit.
  • the spindle is a single spindle having at least two bearings at middle portion thereof as seen from the front side of a creel body and extending right/leftward to form holders for fixedly supporting the bobbins.
  • the non-twist yarn is twisted to be on S-twist by the spindle rotation if the bobbin is positioned so that the yarn unwinding direction is clockwise, while on the left side in Fig. 2, the non-twist yarn is twisted to be a Z-twist by the spindle rotation if the bobbin is positioned so that the yarn unwinding direction is counter clockwise.
  • the bobbins of the non-twist yarn are, of course, positioned to match whereby Z-twist is imparted in the right side bobbin and S-twist is imparted in the left side bobbin.
  • the twisting directions are opposite to each other in the right side bobbin and the left side bobbin, while the rotational speeds, that is, twist numbers thereof are equal to each other.
  • the spindle drive means comprises a plurality of systems, each consisting of a motor and gearing means.
  • the respective system is adapted to drive a group of spindles belonging thereto so that the rotational direction and the rotational speed can be optionally changed.
  • the twist number and/or the twist direction can easily be varied when the quality or thickness of yarns in one spindle group is different from that in an other spindle group, if necessary.
  • Fig. 1 is a side elevational view showing an overall structure of one embodiment of a creel according to the present invention, in which a predetermined number of bobbins 3 (60 on one side and 60 on the other side, total 120 in Fig. 1) are arranged, on each of which a non-twist yarn 2 is wound.
  • the non-twist yarns 2 are unwound and withdrawn from the respective bobbins 3 and supplied in a parallel manner as a sheet of twist yarns 4 to a predetermined machine 13 (for example a loom in Fig. 1) via a group of warping rollers 12.
  • the predetermined machine 13 may be a warper.
  • Fig. 2 illustrates an embodiment of a twisting part, in which the creel 1 is provided with spindles 5 for fixedly holding bobbins 3 and is rotatable therewith, a motor 6 and a gearing device 6a for driving the spindles 5.
  • a bobbin attachment 7 is fitted, having a yarn storage 8 on which a yarn adjustment ring 9 is fitted.
  • a ballooning 10 is generated and a leading end 10a thereof enters the yarn storage 8 of the bobbin attachment 7.
  • the yarn 2 wraps around the periphery of the yarn storage to an extent within one round which varies in accordance with a size of ballooning and then passes by the inner side of the yarn adjustment ring.
  • bobbin 3 used in the creel 1 of the present invention is a cylindrical paper tube in Fig. 2
  • bobbin shapes, materials and structures may be optionally selectable in the present invention. That is, it may be a cylindrical bobbin, a tapered tube or a pirn, except for a double flanged bobbin.
  • a yarn wound on the bobbin may be a twistless yarn or a producer's low twist yarn (included in a "non-twist yarn" as defined in the present invention).
  • a bobbin is of a type from which a yarn can be withdrawn only in one direction, such as a tapered paper tube, the bobbin cannot be held in a reversed position.
  • two kinds of yarn bobbins may be specially prepared in which the yarn unwinding directions thereof are different from each other so that the yarn twisting operation as described above can be similarly applied thereto.
  • a thickness of the non-twist yarn is not limited but can be optionally selected in accordance with the use of the cloth in which the yarn is woven.
  • the yarns may be wound in a doubled state, whereby the same effect as a double-twist yarn can be obtained.
  • While six motors are provided on the rear portion of the creel for driving the spindles 5 in Fig. 1, either a single motor or a plurality of motors may be used. Also the motors may be installed either in the upper or lower portion of the creel.
  • Fig. 2 is a partial view of a twisting mechanism, in which a plurality of spindles 5, not shown, are rotatingly driven by a motor 6 and a gearing device.
  • the gearing device is not limited to a particular type but may be of a chain drive type, a timing belt type or the like, of which a chain drive type is most preferable because the installation cost is inexpensive.
  • a cylindrical paper tube is used as a bobbin and a single spindle 5 is provided while penetrating two central frames so that bobbins 3a, 3b are fixedly held on the right and left extending portions, respectively.
  • This driving system is very simple in structure and greatly contributes to the reduction of installation cost.
  • the bobbin Since the bobbin is fixedly positioned on the spindle so that an unwinding direction of a non-twist yarn coincides with that of the spindle rotation, usually it is necessary that the bobbins held on one side of the spindle are reversely inserted onto the spindle relative to the bobbins held on the other side of the spindle.
  • the bobbin on the right side of Fig. 2 is held so that the unwinding direction of the non-twist yarn is clockwise, the non-twist yarn is twisted by the spindle rotation to be a S twist.
  • the bobbin on the left side of Fig. 2 is held so that the unwinding direction of the non-twist yarn is counterclockwise, and the non-twist yarn is twisted by the spindle rotation to be a Z twist.
  • a bobbin is of a type in which a yarn can be withdrawn from the bobbin only in one direction, it is impossible to reversely hold the bobbin, but in such the case, if two kinds of bobbins are specially prepared in which the yarn unwinding directions of the two kinds of bobbins are opposite to each other, the yarn twisting operation as described above can be similarly applied thereon.
  • spindles may be individually provided on either sides of the creel and driven to rotate in different directions between the right and left side spindles, so that the same directional twist can be imparted. Also in this structure, if the spindle is a hollow spindle so that a core element passes therethrough during the twisting operation, it is possible to use the creel according to the present invention as a covering yarn forming machine.
  • a non-twist yarn 2 is processed to be a twist yarn 4 by unwinding the non-twist yarn from a bobbin 3 while rotating the bobbin 3.
  • a twist number necessary for forming a twist yarn 4 is determined by the bobbin rotation and the withdrawal speed of the non-twist yarn from the bobbin.
  • the creel has a structure for rotating the bobbin 3 in a desired direction and a structure for driving the bobbin at a desired rotational speed.
  • all of twist yarns 4 withdrawn from the creel may have the same twist number and/or the same twisting direction.
  • a part of the twist yarns have a twist number and/or a twisting direction different from that of the other part of the twist yarns.
  • the bobbins 3 arranged on the creel 1 according to the present invention are preferably rotated as a group in a desired direction by the motor 6 or the gearing device 6a in the respective drive system.
  • the rotational speed of the respective drive system is freely adjustable so that a desired twist number can be obtained in the twist yarn.
  • motors 6-1 through 6-6 are positioned on the rear portion of a creel 1, each of which drives a group of spindles arranged on a horizontal plane through a drive means not shown.
  • the respective drive system is adapted so that a rotational direction and a rotational speed thereof can be defined independently from other systems.
  • a twist number corresponding to a thickness and/or the use of a warp yarn can be obtained by changing the rotational speed of the respective drive system.
  • non-twist yarns are supplied as they are while keeping spindles stationary.
  • the rotational direction can be easily changed by using any of known means for switching the rotational direction, or by varying a wrapping arrangement of a belt or chain.
  • a gear box is attached to the motor 6, for reducing the rotational speed of the motor 6 by one tenth.
  • the output rotational speed is 180 rpm.
  • the rotational speed of the motor is controlled by frequency modulation through an inverter under the supervision of a controller in this embodiment. The frequency varies from 0 Hertz to 120 Hertz, which theoretically corresponds to the output rotational speed of 0 rpm through 360 rpm.
  • While one group of spindles arranged in one horizontal plane are driven by the respective drive system including one motor in Fig. 1, it may be possible to drive a plurality of spindle groups by one motor by providing a plurality of gearing means.
  • a distance between the adjacent spindles is determined by taking a size of bobbin usually used and an amount of yarn wound thereon into account.
  • the present invention is not limited to this case but can be used for supplying yarns to a warper.
  • the creel is used for the warper, it is necessary that a motor and a gearing means are designed in a high speed manner, because the winding speed of the warper is far higher than that of the loom.
  • the twisting method according to the present invention is novel and very simple compared with any conventional twisting methods, whereby a twisting cost can be reduced.
  • a warp supply speed is about 1.5 m/min if a weft is picked at a rate of 33 pick/inch, and about 3.0 m/min if a weft is picked at rate of 16.5 pick/inch. Since the weaving speed is relatively low as described above, to obtain a twist yarn having a twist number of 100 t/m, it is sufficient to rotate the bobbin at 150 rpm if a warp is supplied at 1.5 m/min, and at 300 rpm if a warp is supplied at 3.0 m/min. At such a relatively low speed, there is no practical problem even if manufacturing accuracies of spindle, bobbin holding means and bobbin attachment are relatively low.
  • a yarn is twisted only when the yarn is withdrawn from a bobbin while the bobbin is rotated in the yarn unwinding direction.
  • a twist number becomes unstable because the respective position at which the yarn twisting is initiated varies due to the variation of ballooning size in accordance with the change of positions on the bobbin at which the yarn is released.
  • the yarn release itself becomes difficult because the released yarn is wrapped around the bobbin or entangled with the adjacent yarn, which causes a yarn breakage and results in the interruption of the weaving operation.
  • the present invention aims to solve such problems by absorbing the ballooning fluctuation so that a yarn is released in a stable state so as to fix a position at which a twisting is initiated and to maintain a yarn tension substantially at a predetermined level.
  • the twisting system according to the present invention is characterized by two elements; one is a bobbin attachment 7 consisting of a part by which it is fixed on the bobbin and a yarn storage 8 for temporarily storing a yarn length released from the bobbin which fluctuates due to the ballooning, so that the yarn releasing length is compensated, and the other is a yarn adjustment ring 9 mounted on the tip end of the yarn storage for restricting a non-twist yarn so as not to be freely released from the bobbin so that the excessive yarn length is wrapped around the yarn storage if necessary and a predetermined tension is imparted to the yarn.
  • the yarn twisting is initiated upon the yarn has passed the yarn adjustment ring.
  • the bobbin attachment 7, the yarn storage 8 and the yarn adjustment ring 9 will be described in more detail below.
  • Fig. 5(A) illustrates a side view of one embodiment of a bobbin attachment 7 according to the present invention, which is suitably used for an aluminum pirn shown in Fig. 3.
  • Fig. 5(B) illustrates one embodiment of a yarn adjustment ring 9 used while mounted on the bobbin attachment shown in Fig. 5(A), which is preferably an O-ring defined by JIS and made of a synthetic rubber.
  • the yarn adjustment ring 9 may be of any other type, provided it has a predetermined elasticity and friction so that a non-twist yarn 2 is braked thereby not to freely be released from the bobbin, whereby a predetermined tension is imparted to a twist yarn.
  • the yarn adjustment ring 9 is not limited to a mere ring but may be provided with a plurality of whisker-like projections 201 slanted in one direction on the innerside a ring body 200 made of a synthetic resin as shown in Fig. 5(C).
  • the yarn storage 8 is provided on the outer periphery of the bobbin attachment 7 as a groove having a proper width and depth.
  • the width and depth of the yarn storage 8 are preferably determined to be the optimum dimensions by mainly taking a ballooning shape varying in accordance with the kind of non-twist yarn wound on the bobbin 3, yarn thickness, number of filaments, twist number, yarn releasing speed and bobbin rotational speed into account as well as secondarily taking a material, elasticity and friction of the yarn adjustment ring into account.
  • the yarn storage is necessarily designed so that the leading end of the ballooning can enter in the yarn storage even though the non-twist yarn is withdrawn from the bobbin at any point thereof.
  • a hood 80 is preferably provided on the bobbin attachment 7 closer to yarn layers on the bobbin for covering the bobbin.
  • the ballooning While a size of the yarn ballooning varies in the creel according to the present invention upon the release of yarn from the bobbin in accordance with various factors, such as a yarn material, yarn thickness, package diameter, yarn releasing position or a bobbin rotational speed, the ballooning largely expands when the yarn is withdrawn from a forward region of the bobbin, and hardly expands when it is withdrawn from a rear region of the bobbin.
  • the present invention provides the yarn storage 8 on the bobbin attachment mounted at the bobbin end so that the yarn is wrapped around the yarn storage.
  • the yarn adjustment ring 9 is mounted at the end of the yarn storage 8, so that the yarn releasing and twisting can be more stably carried out. Since the withdrawn yarn is restricted by the yarn adjustment ring 9, it is released from the bobbin while being hardly wrapped around the yarn storage 8 when the ballooning size is small, and the yarn is released from the bobbin while wrapped around the yarn storage 8 so that the released length is adjusted when the ballooning size is larger. In this regard, a length of the wrapped yarn did not exceed one round of the periphery of the yarn storage 8.
  • the yarn storage surface is preferably as smooth as possible so as to minimize the tension fluctuation.
  • the same effect is obtained by providing a slight taper on the yarn storage 8 toward an exit; i.e., the yarn adjustment ring 9.
  • the bobbin attachment is manufactured by a molding of plastics, which is relatively inexpensive.

If an excessive tension is applied to yarns when they are twisted, which is not adequate for a yarn material or a yarn thickness, a sensor for detecting the weaving tension and positively delivering the yarns may be provided in the above group of rollers.
  • a single spindle 5 has at least two bearings in a central portion thereof as seen from the front side of the creel, and is adapted to fixedly hold bobbins on both sides of the group of bearings.
