Definitions

  • This invention relates to a thread-storage, thread-advancing device. More particularly the invention relates to a reel or cage-like device for storing and advancing filamentary material lengthwise thereof in a plurality of substantially helical turns and in a manner compatible with such after-treatments as may be required in any particular process for the manufacture of filamentary material.
  • the present invention is applicable in the manufacture of filamentary material from various materials, such as viscose, cuprammonium, nitrocellulose, cellulose acetate, acrylonitrile polymers, nylon, polyesters, etc., for convenience of description the invention will be described as it is applicable to the manufacture of continuous filaments or threads from acrylonitrile polymers, it being understood, however, that this is merely intended in an illustrative sense and the invention is not to be limited thereby but only insofar as the same may be limited by the appended claims. In fact, as will be seen from the detailed description of the invention hereinafter, the present invention may readily be adapted to the treatment of natural fibers in the form of threads or yarns.
  • a general object of the present invention to provide a thread-storage and advancing device or reel which overcomes the above disadvantages and in which the thread or filament is conveyed, while being simultaneously treated, at high speeds.
  • Another object of the invention is to provide a thread-storage and advancing reel wherein the filament is relaxed while being conveyed and simultaneously treated.
  • It is a further object of the invention to provide a thread-storage and advancing reel which is easily threaded up.
  • a thread-storage and advancing reel wherein the filament is laid up internally thereof in a series of substantially helical turns and held in place by means of centrifugal force.
  • Another object of the invention is to provide a thread-storage and advancing reel wherein it is possible to treat the advancing filament with more than one liquid treating medium.
  • a thread-storage and threadadvancing reel mounted in vertical position comprising a cage formed by two reel members each provided with a number of circumferential bars which interdigitate to form a cylindrical filament-supporting surface within the cage, said reel having stationary means for laying the thread up on the inner surface of said bars, means for introducing liquid medium internally of said cage at various points therein with liquid removing means adjacent various areas of said cage and means for causing relative movement of said bars during rotation of the reel whereby the filament laid up internally thereof is advanced in a series of substantially helical turns.
  • the circumferential bars are so constructed that the internal diameter of the cage is less at the filament exit end than at the filament introduction end whereby the filaments are advanced through the reel or cage in relaxed condition.
  • Figure 1 is a sectional side elevation view of the pre ferred reel of the instant invention.
  • Figure 2 is a view taken along the line 2-2 of Figure 1.
  • a filament or yarn or thread 2 is fed by means of the feed roll 3 to the reel 4.
  • the filament .2 is removed from the reel by means of the drying rolls 5, Where, it will be noted, the filament makes several courses thereabout, depending upon the operating temperature of the drying rolls and the speed of the filament.
  • the drying rolls shown may be heated internally by means of steam or hot water, and the like. Any conventional drying means may be employed with the reel of the instant invention, such as a series of drying rolls arranged in two tiers where the filament makes one pass over each'roll, or the filament may be passed through a suitably heated drying chamber, etc.
  • the dried filament leaving the drying rolls is collected in the usual manner, such as directly on bobbins without twisting or with twisting, as on a cap spinning machine.
  • the reel 4 consists of a stationary housing ormember 6 rotatably mounted on which is the rotating housing or member 7.
  • the housing or-support 7 rotates about the stationary housing 6 on the bearings 8.
  • Integrally fastened to the rotatable housing 7 is a circular basket 9 having a series of bars 10 integrally fastened thereto and extending downward internally of the stationary housing 6.
  • a second set of bars 14 Positioned in between the bars 10 is a second set of bars 14 which are movable vertically and horizontally to and from the center of the cage formed by the bars 10 and 14.
  • the bars are spaced so as to allow free movement of the bars 14 but bars 10 and 14 together form a substantially continuous surface.
  • the vertical and horizontal movement of bars 14 is accomplished by means of cam action.
  • In the face of the inner wall of stationary housing 6 are two grooves or slots 15 and 16 extending around the inner circumference thereof and it will be noted that said slots are inclined with respect to the horizontal plane of the reel. This inclination of the slots causes the vertical movement of the bars 14 as explained in more detail hereinafter.
  • Each of the bars 14 has two cam followers 17 and 18 integrally attached thereto which ride in slots 15 and 16 respectively.
  • the c am followers are clearly shown in Figure 2.
  • the slots 15 and 16 in addition to being inclined with respect to the horizontal plane of the reel, are eccentric with the housing 6, that is, the axis of the slots are offset to the axis of the circular housing 6. While the inclination of the slots imparts vertical motion to the bars 14, by reason of the cam followers 17 and 18 riding in slots 15 and 16 as the housing 7 is rotated, horizontal movement toward and away from the center line of the reel is likewise imparted to bars 14 by reason of the slots being eccentric to the axis of housing 6. This horizontal movement of the bars 14 is clearly ascertainable by reference to Figure 2 of the drawing.
  • the bars 14 are supported in the cage by reason of the cam followers resting in the slots 15 and 16.
  • a ring 19 which is integrally fastened to the bottom edge of the bars It This ring acts as a support or retainer for the movable bars 14 and it is to be noted that all of the bars have a cut-out portion 20 at the bottoms thereof to accommodate the ring support 19.
  • Each of the bars 10 and 14 are tapered. That is, they are wider at the bottom end thereof than at the top. Thus, as the filament is passed through the reel it is relaxed, or is in a relaxed state due to the decreasing circumference of the inner surface of the reel formed by the bars from the entrance end to the exit end thereof. This relaxation of the filament is accomplished when the feed roll 3 and the drying rolls are driven at the same peripheral speed.
  • the reel 4 is laced up by means of the funnel-shaped jet 21 which is stationarily mounted so as to extend downwardly internally of the reel in such position that the filament passing therethrough will be laid-up against the surface formed by the bars and 14 at the upper portion thereof.
  • the jet 21 may be mounted in any desirable manner but preferably, is not attached to any portion of the reel 4.
  • Extending outwardly from the upper portion of jet 21 is a pipe 22 which conveys air, water, or other gas or liquid to the jet 21 to assist in passing the filament therethrough.
  • the liquid treating tubes 23 and 24 Positioned adjacent the reel 4 and extending downwardly internally thereof are the liquid treating tubes or conduits 23 and 24.
  • the liquid treating tubes are positioned close to the inner wall or surface formed by the bars of the reel and are perforated at the lower'ends thereof in order that the treating liquid or wash Water may be sprayed on the filament passing through the reel.
  • the tubes 23 and 24 are sealed off at their lower ends.
  • the tube 23 extends downwardly almost to the circular channel or groove 26 on the inner wall of the stationary housing 6.
  • a series of openings or channels 27 extending through the housing 6 connect the channel 26 with the circular trough 28 extending around the outer wall of the housing 6 and fastened thereto.
  • a liquid removing pipe or conduit 29 is fastened to the trough 28.
  • the tube 24 extends down to the tapered portion 6a of the wall of housing 6.
  • the tapered portion 6a of the inner housing wall forms an opening communicating with the circular trough 30 fastened to the lower end of housing 6.
  • a liquid runoff pipe or conduit 31 is fastened to the trough 30.
  • the reel pictured in the drawing operates essentially as follows: the filament formed from an acrylonitrile polymer, preferably containing at least percent by weight of acrylonitrile in polymerized form, is fed by the feed roll 3 to the funnel-shaped jet 21 where the water or air, entering through the pipe or conduit 22, assists the passage of the filament therethrough and directs the same against the surface of the bars 10 and 14, which are rotating at high speeds.
  • the filament is held in place on the bars by means of centrifugal force. With the present apparatus filament speeds up to 2000 feet per minute are possible without damaging the filament and still allowing sufiieient time for relaxation of the filament and liquid treatment thereof.
  • the filament is in a relaxed state due to the taper of the bars 10 and 14.
  • the taper of the bars determines the percent or degree of relaxation of the filament.
  • the relaxation of the filament can be increased or decreased by varying the degree of taper in the bars 10 and 14.
  • the filament is then removed from the reel by the drying rolls 5 which pull or peel off the filament from the inner reel surface continuously at the point Y.
  • the treating liquid entering by means of conduit 23 is sprayed on the filament while in the upper portion of the reel. Due to a slight space between each pair of bars 10 and 14, the liquid passes therebetween by centrifugal force and is thrown against the inner wall of the housing 6. The liquid runs down the wall into the channel 26 out through the conduits or openings 27 into the trough 28 from which it is removed by the conduit 29.
  • the second treating liquid or wash water enters through the conduit 24 and is sprayed on the filament in the lower portion of the reel. By the same action as above, the treating liquid or wash water runs down the inner wall of housing 6 into trough 30 and is removed therefrom by means of the conduit 31.
  • the reel shown in the drawing is particularly adapted to the treating of filaments formed from acrylonitrile polymers.
  • the filament is first washed with water, using conduit 23, and then the finish is applied by means of conduit 24. Thereafter the filament is dried and wound on bobbins.
  • conduits for conveying treating liquid internally of the reel While in the embodiment of the invention shown in the drawing there are two conduits for conveying treating liquid internally of the reel, only one or more than two such conduits may be employed. In such cases, the necessary adjustments in the size of the reel would have to be made. For example, the reel would have to be of greater length when employing more than two treating liquid conduits, depending of course upon the time of treatment with each liquid.
  • Additional liquid removal troughs such as 28, would likewise be employed with each additional treating liquid conduit.
  • additional treating liquid conduits is particularly desirable when making a viscose rayon filament where the same is treated with a desulfurizing composition, washed, treated with a bleaching agent and washed again.
  • the taper of the bars wil cause the filament thereon to relax as it passes through the reel.
  • the treating fluids and/or washing liquids employed be at elevated temperatures.
  • a temperature of 210 F. has been found to be satisfactory. The temperature employed will depend upon the nature of the particular filament being treated.
  • the present thread-storage and thread-advancing reel is particularly advantageous in that it is capable of eflicient operation at high speeds thus affording increased production.
  • a multiple of washing and treating agents may be employed on one reel, the process is simplified and there is a decrease in cost of equipment.
  • the present reel is easily threaded up which has been a particularly troublesome problem with many prior art reels.
  • treatment with a liquid has posed a problem, and particularly at high speeds. If the liquid is sprayed on the filament on a device of that kind, considerable spray is encountered due to centrifugal force with the natural attendant difliculties.
  • a high speed thread-advancing and thread-storage reel comprising a cylindrical cage formed by-two sets of circumferential inter-digitating bars, the first set of said bars being stationarily mounted with respect to the second set of bars, said second set of bars being movably mounted vertically and horizontally toward and away from the center line of said cage, means for rotating said cage, means adjacent the entrance end of said cage for laying a filament up on the surface of said bars internally of the cage, means for introducing a liquid internally of said cage in contact with the filament, liquid removing means adjacent the cage, and means for moving the second set of bars vertically and horizontally as the cage is rotated whereby the filament is advanced through the cage in a series of substantially helical turns, said cage having a diameter at the exit end thereof smaller than at the entrance end whereby the filament advancing therethrough is treated in a relaxed condition.
