Definitions

  • ABSTRACT A multispindle double twist twisting machine having twisting spindles arranged in rows on either side of an elongated, vertically positioned drive housing which substantially encloses the driven elements of the twisting spindles and contains drive means to rotate said spindles, preferably including a tensioned belt entrained over rollers on a common drive shaft, the spindles extending substantially horizontally outwardly from the housing and associated with a corresponding number of winding means arranged in similar rows above or below the spindles with a preliminary drawofi means including a common rotatable shaft which is preferably located at about the same level as the row of winding means furthest removed from the spindles.
  • the enclosed drive housing for the spindles is advantageously of soundproof construction with means for circulating cooling air therethrough, thereby providing a compact, efficient
  • 1,900,926 discloses one particular two-sided double twist twisting machine containing a large number of twisting spindles mounted along the entire length of a spindle rail or supporting means in the form of two rows in staggered relationship one over the other and having a corresponding number of winding units or takeup spools arranged above the double twist twisting spindles.
  • This arrangement provided a certain improvement over the more common double twist twisting machine having only a single row of twisting spindles on either side of the machine.
  • the axes of rotation of the spindles are arranged in a vertical position or a position slightly inclined to the vertical. A machine of this type still presents appreciable problems in its operation.
  • the arrangement of the twisting spindles in vertical or substantially vertical positions has the serious disadvantage that it requires a very tall supporting structure for the spindles and winding units, and this in turn requires the use of auxiliary devices in order to reach the upper parts or members of the machine.
  • Another serious drawback of this multispindle machine construction resides in the fact that the drive means for the spindles with a large number of deflection rollers is accompanied by an extraordinarily severe development of noise even when limited to a single continuous drive belt operating all of the spindles in a machine unit. This noise level is so high as to constitute a serious hazard to the health and safety of operating personnel, any commercial installation causing a noise level far above valves which should normally be observed in any human environment.
  • Still another object of the invention is to provide a common spindle drive shaft and/or other rotatable common shafts in conjunction with the drawoff means and winding means for individual threads so that a large number of individual twisting and winding units can be operated from a common drive means while still permitting individual groups of spindles to be easily removed from operation when interchanging feed spools and wound bobbins.
  • a multispindle double twist twisting machine which comprises an elongated, vertically positioned and substantially enclosed drive housing; a plurality of rotatable twisting spindles arranged in rows along the length of said housing on either side of a longitudinal vertical plane through the center of said housing, the driven elements of said twisting spindles being contained within said housing and said spindles extending substantially horizontally outwardly from said housing; drive means located within said housing for operable engagement with the driven elements of said spindles; winding means as sociated with each twisting spindle for taking up thread therefrom and mounted above or below each spindle in rows of substantially the same length as said spindle rows; and preliminary drawoff means including a common rotatable shaft on either side of said housing for transporting thread from each twisting spindle to its associated winding means.
  • the twisting spindles are preferably arranged in a number of rows on each side of the machine, it being most convenient to provide two superimposed rows of the spindles with the spindles of one row being staggered to occupy vertical planes separate from the spindles of the adjacent row on the same side of the machine. It is essential, however, for the axes of the rotatable twisting spindles to extend substantially horizontally through the drive housing to the machine so that the driven elements of the spindles including their bearings are contained within the enclosed drive housing.
  • each common drive box it has been found most convenient to rotatably mount about 16 to 48 and preferably 24 to 40 twisting spindles on both sides of the machine, and it is also preferable to provide an individual continuous drive belt for each group of four oppositely disposed twisting spindles, i.e., the adjacent upper and lower spindles of the two rows on each side of the machine.
  • This permits a single continuous belt to be entrained over the drive elements of each four individual spindles around one belt-engaging roller on the common drive shaft for said spindles and around one tensioning roller which is preferably mounted within the housing on a swingable axis of rotation with means to resiliently urge the tensioning roller into driven contact with the continuous belt.
  • FIG. 1 is a partly schematic cross-sectional view taken transversely on a vertical plane through the elongated drive housing containing two rows of double twist twisting spindles on either side of the machine, the lower supporting structure or framework and certain other elements being omitted;
  • FIG. 2 is a partly schematic side elevational view of one unit of the elongated multispindle double twist twisting machine of FIG. 1, including a fragmentary portion of adjacent units which can be mounted end to end to form a large bank of twosided double twist twisting units;
  • FIG. 3 is a fragmentary view of the drive housing in cross section along a vertical plane passing through the common drive shaft for the rotatably mounted spindles on the side of the machine, particularly to illustrate a preferred embodiment of the drive means including a number of continuous belts associated with two spindles on each side of the machine;
  • FIG. 4 is a fragmentary view of a single continuous belt drive capable of being engaged or disengaged by a swingable or tiltable tensioning roller pivotally mounted between the two sides of the machine;
  • FIG. 5 is a fragmentary view of one upper corner of the drive housing of the machine to illustrate a sound-proof or sound-absorbing lining together with the position of one observation mirror;
  • FIG. 6 is a side elevational view of three interconnected or adjoining multispindle double twist twisting units with means for blowing cooling air through the spindle drive housings of all three units, the position of all individual twisting spindles and corresponding winding means being omitted but being essentially identical to FIGS. 1 and 2.
  • Each building-block or multispindle unit essentially includes a basesupported framework including an upper drive housing 1 provided with an upper cover or lid 2 which is adapted to be easily removed or pivotally hinged to open along the flanges 3 extending longitudinally near the upper end of the housing 1.
  • This provides ready access to the drive means contained within the housing, and if desired, each unit can have a plurality of adjoining lids or covers 2 to be separately opened above individually driven groups of spindles.
  • vertical partitions can be provided between individual positions of drive belts as a safety factor. Such individual variations have not been shown since they can be readily visualized in the existing structure.
  • each multispindle twisting unit also includes a lower framework 4 to receive the winding or takeup means for the twisted thread as well as associated guide rollers, transporting rollers and the like (see FIG. 2).
  • a small fragment of each adjoining multispindle double twist twisting unit is also shown in FIG. 2 with the corresponding drive housing la and lb as well as the lower supporting frames 4a and 4b. Three such units are more generally shown in a complete side elevational view in FIG. b.
  • the lower supporting framework 4 can also be partially enclosed by a housing but this is generally unnecessary since the winding means and the transporting or guiding rollers for the thread usually operate at a much lower noise level than do the twisting spindles.
  • Each drive housing 1 is a substantially rectangular boxlike structure enclosed on all sides including the cover 2.
  • An upper and lower row of double twist twisting spindles 5 and 6 are rotatably mounted in staggered positions along the length of the housing 1 on either side thereof so as to extend horizontally or substantially perpendicularly to a vertical plane extending longitudinally through the center of the housing.
  • the driven elements including the rotatable spindle shafts 7 and 8 as well as the bearing means 9 and 10 are contained completely within the housing 1 which is preferably of sound-proof or sound-absorbing construction.
  • Each spindle is adapted to receive a feed spool or bobbin package 11 and 12 in the conventional manner of double twist twisting spindles.
  • the staggered arrangement of the spindles 5 and 6 in two rows on each side of the machine permits the closest possible packing or distribution of the feed spools l1 and 12 and represents a substantial saving in space with reference to the total capacity of an individual multispindle unit.
  • the threads T being drawn from each feed spool 11 and 12 are drawn outwardly through the extended spindle guides 13 and 14 which are likewise supported horizontally along the spindles axis.
  • the threads are eventually taken up or wound on a plurality of windingor takeup spools 15 and 16, corresponding in number of the twisting spindles S and 6 and preferably arranged below or underneath these twisting spindles in a corresponding number of rows and in corresponding staggered positions.
  • These takeup spools can be rotatably mounted on a common shaft 15' and 16' in each row, this common shaft or separate individual shafts for each takeup spool being supported on the framework 4 in any conventional manner.
  • Each individual takeup spool 15 or 16 is preferably rotated by frictional engagement with a corresponding drive roller 17 and 18 which can be easily driven through a common drive shaft 17' and 18', respectively.
  • a traversing mechanism or other auxiliary elements may also be associated with each of the takeup spools 15, 16 and their as sociated drive rollers 17, 18 in order to distribute the thread back and forth around the circumference of the takeup spools as is quite conventional in this art.
  • Such traversing mechanisms or similar elements require relatively little space so that the individual winding means can be spaced quite closely together on axes of rotation which preferably extend parallel to the longitudinal vertical plane of the double twist twisting machine.
  • This arrangement also permits the winding means to be positioned either above or below the twisting spindles and completely within their outermost horizontal extension such that the maximum width of the machine is dependent solely upon the horizontal extension of the spindles.
  • the two rows of twisting spindles 5 and 6 are most advantageously located on the uppermost or top level of the double twist twisting machine so that the drive housing I is supported on top of the framework 4 and the winding means or takeup spools 15 and 16 being located underneath or directly below the spindles 5 and 6.
  • the drive housing 1 and its spindles 5 and 6 it is also feasible to mount the drive housing 1 and its spindles 5 and 6 on the lower level of the double twist twisting machine with the winding means including takeup spools 15 and 16 mounted directly above the housing 1 on the connected framework 4. This arrangement would substantially correspond to an inversion of FIGS. 1 and 2 although it would still be preferable to maintain the cover 2 on the top side of the drive housing I.
  • the individual groups or rows of winding means i.e., corresponding to takeup spools l5 and 16, must be spaced along the housing so that the length of the entire group of winding units corresponds to the length of the same number of twisting spindles so as to fall within the confines of the total length of an individual drive housing 1 and its associated framework 4. Otherwise, it would not be possible to interconnect a plurality of individual double twist twisting machine units in a compact end to end relationship as shown in FIG. 6.
  • each winding or takeup spool 15 or 16 as the primary winding means directly below its associated twisting spindle 5 or 6 such that the vertical plane through the axis of the twisting spindle extends transversely the axis of the winding means at about its midsection, This assures that there will be no interference with the threads T as they are wound with a traversing movements on the spools 15 or 16 with reference to the adjoining spindles and winding means.
  • the individual winding units or means can also be subdivided into smaller groups so as to be individually rotated by a smaller group of drive rollers 17 or 18, provided however that the total number of winding means should correspond to the number of twisting spindles and the composite length of the winding units should correspond approximately to the length of the drive housing 1 containing the complete group of spindles.
  • each side of thedouble twist twisting machine there is preferably arranged on each side of thedouble twist twisting machine only a single common rotatable shaft 19 or 20 in order to operate a preliminary drawoff means.
  • a common shaft is positioned in such a manner that the servicing or maintenance of the rows of winding means further removed from the drive housing I and spindles 5 and 6 is as convenient as possibfe.
  • this common drawoff shaft 19 or 20 is thus preferably located at about the level or somewhat below the lowest row of winding means or somewhat above the uppermost row of winding means, depending upon whether these winding means are arranged below or above the twisting spindles 5 and 6.
  • This preliminary drawoff means is also preferably located almost directly below or slightly inside of the spindle guides 13 and 14 so that the transported thread T is directed in a substantially vertical path between the spindles and the preliminary drawoff means.
  • FIG. of the drawings two different constructions of the preliminary drawoff means are illustrated on the opposite sides of the double twist twisting machine.
  • a conventional drawoff shaft 19 below the lower winding means 16, 18 wherein the individual delivery rollers or so-called lead rollers 21 are seated directly on the rotatable shaft 19.
  • Two deflection rollers 22 are required in this instance to provide a sufficiently large encircling angle of the thread around the roller 21, i.e., so that the thread is maintained sufficiently in driven contact with this roller to ensure a steady delivery to the winding means.
  • the construction of the delivery or lead roller permits a large encircling angle of the thread therearound without the use of deflection rollers.
  • the delivery roller 23 is seated directly above a continuous or common drive shaft which is equipped with frictionally engaged drive wheels 24 or similar drive gears, belts or the like.
  • These delivery rollers 23 can be individually secured to a short shaft 25 (as shown in FIG. 2) with the delivery roller 23 and a driven wheel or gear 26 at either end of the short shaft 25 so that each thread delivery roller 23 is operated by an individual driving wheel or gear 24.
  • a somewhat longer shaft 25' can carry on each end a preliminary drawoff or delivery roller 23 while carrying the driven wheel or gear 26 therebetween for operable engagement with a single drive wheel or gear 24 on the common drive shaft 20.
  • Suitable bearing means can be provided to support all of the driving or driven shafts in a conventional manner on the supporting framework 4.
  • conventional motors or the like are employed for driving individual shafts throughout the construction ofthe multispindle double twist twisting machine of the invention. Such motors have not been illustrated since they are employed in a generally known manner and can be in the form of conventional variable speed motors in order to properly adjust the twisting and winding rate of the individual threads.
  • the preliminary drawoff means shown the right side of FIG. 1 has certain advantages in terms of its low cost of construction and the ease by which threads can be engaged on the delivery or lead rollers 23.
  • the provision of two delivery rollers 23 on one shaft 25' as shown on the right-hand side of FIG, 2 has the advantage of low cost.
  • the first-described arrangement in which each delivery roller 23 is individually secured and driven on a short shaft 25 as shown on the left-hand side of FIG. 2 has the advantage ofa so-called "unidirectional thread application process. This means that when reloading the machine, which as experience has shown must be carried out very rapidly, it is not necessary to grip around or embrace the delivery rollers 23 when laying the individual threads T onto these rollers.
  • the individual threads T travel in a path between the preliminary drawoff means as represented by shafts 19 or 20, they can be directed individually into each winding unit by suitable deflection or guide rollers 27 and 28 (as shown in FIG. 1).
  • a single set of rotatable preparation rollers 29 can be arranged on each side of the machine for tangential contact with the path of the threads as they are conducted from the preliminary drawoff means to the deflection or guide rollers 27, 28, these preparation rollers 29 being of conventional construction and adapted to rotate in a tray or container 30 of a liquid preparation or finishing agent such as lubricants or the like.
  • deflection or guide rollers 27,28 as well as preparation rollers 29 are possible within the scope of the invention, but it is again desirable for the axes of rotation of such rollers to be arranged substantially parallel to the vertical plane passing longitudinally through the center of the drive housing 1.
  • Such an arrangement permits the collective path of all of the threads to be contained substantially within a common plane or planes so as to achieve a very uniform and symmetrical arrangement of all of the individual moving parts.
  • the individual twisting spindles 5, 6 are driven by means of a continuous or common drive shaft 31 as illustrated in FIGS. 1, 3 and 4.
  • the drive means for the spindles preferably includes a number of individual continuous drive belts 32 which are entrained over and set in motion by a corresponding number of belt-engaging rollers or pulleys 33 secured at intervals along the continuous shaft 31.
  • the drive means also includes the spindle shaft or whorls 7 and 8 with the continuous drive belt 32 entrained over a number of these driven elements of the spindles, preferably so as to drive two spindles on each side of the machine, e.g., one oppositely disposed pair of spindles in the upper rows and one oppositely disposed pair of spindles obliquely adjacent thereto in the next adjacent row.
  • the continuous belt drive is preferably entrained over a tensioning roller or pulley 34 located above the common drive shaft 31. This tensioning roller 34 is preferably seated on a swinging or pivoted bridge member 35 which can be resiliently urged into position so as to increase the belt tension. As shown in FIGS.
  • this bridge 35 can be spring-loaded by means of the springs 36 with screw means 37 for adjusting the tension exerted on the bridge. While such spring-loading is preferred, it is also feasible to load the bridge 35 with a weight or any other conventional means to swing the tensioning roller 34 into positive engagement under a predetermined tension with the belt drive 32.

It will also be noted that only four spindles are placed out of operation during the disengagement of the tensioning roller 34, so that all of the remaining spindles in each machine unit or adjoining machine units can continue to operate while exchanging an individual drive belt or during a temporary shutdown of one small group of spindles and associated winding means. It is not necessary to disassemble individual shafts or to remove any of the individual parts of the machine when exchanging drive belts.
