Definitions

  • This invention relates to the handling of strandular materials and more particularly to a method and apparatus for processing freshly spun synthetic threads such as rayon, nylon, Vinyon, casein and the like.
  • the invention will be described in connection with the manufacture of viscose rayon as this type of process is more generally used than the other processes.
  • the thread-guiding surface was provided on a freely rotatable roller or a driven roller commonly called a godet.
  • godets have been, and are being, used commercially in the viscose plants producing rayon according to the discontinuous method wherein the acid thread is initially collected in a centrifugal bucket or on a bobbin prior to aftertreatment.
  • the invention further contemplates a process in which thread is advanced through a treating orvlstorage zone in the form of a multiplicity of helices which are guided laterally during their advancement.
  • Another object of this invention is the provision of a cage member which rotates a series of laterally spaced helices about a single axis and coacts with a complementary means at the periphery of the cage to physically guide the thread in the form of a multiplicity of helices laterally of the cage member.
  • the invention has, as an additional object, the provision of a continuous spinning system in which one or more thread-storage, thread-advancing devices are employed for processing freshly formed viscose rayon threads prior to their collection in the form of a package.
  • Figure 1 is a longitudinal sectional view through a reel constructed in accordance with this invention
  • Figure 2 is an elevational view of one of the spur gears illustrating the interrupted saw-r toothed thread formed on the crowns of the gear teeth;
  • Figure 3 is a transverse sectional view through the reel illustrated in Figure 1;
  • Figure 4 is a fragmentary elevational view of the outer end of the reel shown in Figure 1;
  • Figure 5 is a longitudinal sectional view of a modified form of reel constructed in accordance with this invention.
  • Figure 6 is an elevational view of one of the spur gears utilized in the modified construction illustrated in Figure 5 with the bore formed therein being shown in dotted lines;
  • Figure '7 is a further modified form of reel constructed in accordance with the present invention, the reel being provided with a lateral series of spur gears for permitting a plurality of zones of treatment of strandular material on one reel;
  • Figure 8 is a diagrammatic view common to each of the forms of reels referred to, illustrating the position of the strandular material as it is advanced longitudinally of a reel when the relative motion of the parts thereof is such as to maintain a spacing of the convolutions of strandular material the full distance between the threads of the gears;
  • Figure 9 is a diagrammatic view of a modified form of Figure 5, wherein the bars of the cage member converge and the spur gears are tapered so that the strandular material is permitted to contract thereon.
  • numeral Ill designates a driving shaft having keyed thereto, for rotation therewith, a circular front plate ll of an outer cage designated generally as l2.
  • Plate I I is provided with a. central opening l3 for receiving the reduced portion I4 of shaft l0.
  • Crown nut I5 is threaded upon portion l4 for retaining the outer cage in position.
  • a tubular shaft I6 is mounted upon shaft III for relative rotary motion with respect thereto.
  • Shaft I6 is formed with a flange H, which bears against hub l8 of the rear circular plate IQ of cage l2.
  • Circular plates II and H! are provided with openings 20 and 2
  • Each of the bars 22 have reduced threaded portions 25, extending through openings 2
  • the outer cage I2 is thus formed as a rigid construction, in which the plates thereof are securely held in spaced position by means of the bars 22, and the driving of shaft ID will cause the rotation of the cage and relative rotation of the cage with respect to tubular shaft 16 when shaft I6 is maintained stationary or is driven at a speed diiferent from or in a direction counter to shaft ID.
  • gears 36 when meshed with the bars will extend between the bars to such extent that the sawtoothed screw-thread sections 39 cut on the crowns of the teeth will project beyond the circumference of the cage as formed by the bars 22 with the bases of the threads just within the cage circumference.
  • Thread sections 39 are so out upon the crowns of the teeth 38 of each of the spur gears that they jointly present on each gear an interrupted screw-thread as illustrated in Figure 2. While other types of screw-threads may be utilized the saw-toothed thread has been found to give very satisfactory results, in that, substantially the en tire threaded surface of each gear is made up of faces sloping toward the delivery end of the reel.
  • the dimensions of the saw-toothed screw-thread may vary depending on the number and size of the spur gears, e. g., where four spur gears are employed, the saw-toothed screw-thread may vary from /:i2 to V in height and to V4" in width.
  • spur gears 36 may be employed in the nature of planets meshing with the cage I2 as a ring gear. While it has been found that the use of four spur gears is highly satisfactory, the number of spur gears may be varied so long as a sufficient number of spur gears are utilized to effect the desired advancement of the strandular material in helical form longitudinally of the reel.
  • continuous strandular material such as freshly spun rayon yarn passed from a coagulating bath
  • continuous strandular material is delivered to a position on the surface of the reel immediately adjacent the rearmost thread convolution as illustrated in Figure 8.
  • outer cage I2 is continued to be rotated and tubular shaft IS with plates 28 and 29 and axles 34 are either maintained stationary or rotated relative to cage l2
  • the tendency to wind the continuous thread upon itself on the bars 22- of the cage is prevented by the lateral guiding of the strandular material, i. e., longitudinally of the reel toward the end plate ii.
  • each tooth of a given spur gear meshing within the space between succeeding bars will present a section of saw-toothed thread sloping toward the front plate II and as each following thread section moves outwardly from between the bars the sloping surface of its teeth will engage the strandular material and gently move it toward th delivery end of the reel. Since the thread sections on the teeth of each spur gear 36 forms an interrupted screw-thread around the gear. each succeeding tooth of the gear will present a thread section slightly advanced beyond the section which effected the movement of the preceding portion of strandular material.
  • Each of the spur gears as shown are formed with twelve teeth and therefore when the relative positions of advancement between the portions of the strandular material first engaged by the gear and the portions engaged by the twelfth tooth will be one screw-thread apart.
  • the movement of each portion of the strandular material by the screwthread section is from the position where it is engaged by the sloping thread surface to a position immediately overlying the base of the thread.
  • the particular spur gear 36 underlying the point of feed of the thread to the reel will depend upon whether the tubular shaft I6 is being held stationary, rotated at a different speedbut in the same direction of the cage, or whether it is being rotated in a counter direction.
  • the strandular material delivered from the reel may be directed to a point of collection or it may be subjected to treatment upon a similar reel or reels, or upon any one of the well known treating devices. This is particularly important when the reels are being utilized in the production of viscose rayon.
  • FIGS and 6 illustrate a reel which operates on the same principle as the reel shown in Figures 1-4, inclusive.
  • the drive shaft 40 of this modified form is reduced at 4] and receives a hub 42 of a single disc 43 to which a series of spur gears 44 are attached by a stub axle 45 the end of which is screwed into disc 43 as indicated at 46.
  • Disc 43 is keyed to the shaft and secured into position by a crown nut 41.
  • a sleeve 48 is mounted on each axle for properly spacing the end thereof to accommodate the respective spur gears 44 and spacers 49 are employed to properly align the spur gears on the stub axles.
  • a tubular shaft 50 is mounted for rotation upon shaft 40.
  • adapted for connection to a source of power (not shown) is keyed with key 52 to shaft 50 and abuts against the hub of a circular disc 53 provided with a series of openings 54 adjacent the periphery thereof.
  • a series of spaced bars 55 are anchored within the openings 54 and are secured therein by nuts 56.
  • bars 55 may be extended and bent toward the center of the reel to act as guards.
  • a circular disc-like shield may be fastened at its periphery to the outer ends of bars 55.
  • Each of the spur gears 44 is identical in formation with the spur gears 36 described in connection with Figures 1-4, inclusive, except for the counterbore 51 at the outer end of the center bore thereof which enlargement is adapted to receive the head 58 of the stub axle 45. 4
  • the modified form of reel illustrated in Figure 5 operates in the same manner as the reel illustrated in Figures 1-4, inclusive, with the exception that the outer member carrying the bars 55 is driven by the tubular shaft while the inner member carrying the spur gears 44 is driven by the circular shaft. It is clear, therefore, that in order for the reels of the two forms to operate identically the shafts 40 and 50 of the form shown in Figure 5 are driven in a direction opposite to the corresponding shafts of the form shown in Figures 1-4, inclusive.
  • FIG. 7 The modification shown in Figure 7 is: similar to the form of reel illustrated in Figures 14, inclusive, in that the outer cage is driven by shaft 59 and the inner member is driven by tubular shaft 80.
  • strandular material may be formed into three separate helices longitudinally along the cage (it so that various treatments of the strandular material may be effected on the same reel.
  • front and rear discs 62 and B3 are mounted in spaced relation upon tubular shaft and they have secured therein axles 64 upon which are mounted for free rotation spur gears 65.
  • the spur gears are maintained in proper alignment by means of spacers 66.
  • Spur gears 65 are identical in construction with spur gears 36 in the form illustrated in Figures 1-4, inclusive.
  • the bars of the outer cage members define a cylinder and the spur gears are also of a cylindrical configuration.
  • Such constructions effect no stretching or let-oil on the reels per se. although any desirable stretching or contraction may be accomplished between the reels by driving the reels at different peripheral speeds or by introducing godets therebetween.
  • the invention further comprehends modifying the reels by mounting the bars of the cage members so that they converge and if the degree oi convergence makes it necessary, then the spur gears can be tapered to a corresponding extent.
  • the yarn will be stretched or permitted to'contract.
  • a reel of the type shown in Figure 9 has particuiar utility in the drying of rayon and ofiers advantages over prior drying reels which have never been entirely satisfactory because when utilizing the angle-axis principle on conical reels, the yarn as it dried had a tendency to ride back on. itself instead of advancing laterally of the reel.
  • the yarn at is physically guided laterally by the sawtooth screw thread sections 66, and accordingly, wiil be ad vanced thereon toward the smaller end to effect any desired amount of contraction during dry ing.
  • the driving shaft 69 drives the outer cage 10, and tubular shaft ii is mounted on shaft 655 for relative rotation therewith.
  • a gear ?2 is keyed to tubular shaft ii tor effecting rotation thereof, which in turn drives spur gears i3.
  • the present invention has par ticular utility in. the treatment or synthetic yarns, such as viscose in the wet state, although the' principle here involved may be adapted to the processing of dry yarns. It is to be understood that various modifications may be made without departing from the spirit of the invention, as the scope thereof is to be limited only to the extent of the appended claim.
  • An apparatus for efiecting a plurality of sequential treatments on rayon thread which comprises an elongated reel having annularly arranged spaced bars with reduced outer surfaces forming longitudinal ridges and thereby a series 01 annularly spaced points of support for the thread, means for rotatably supporting the reel, a plurality of means for progressively presenting surfaces intermediate each of the thread supporting points, each of last said means being separated axially but in axial alignment for moving the thread transversely of the reel in separated series of closely spaced convolutions and godets between each series of convolutions to convey the thread therebetween.
