Definitions

  • This invention relates to equipment used in the textile field.
  • it relates to a machine which permits the exposure of runnin lengths of shaped articles such as yarn to fluid.
  • the fluid treating apparatus must have a means for disposing of exhaust fluid which is emitted from each end. This feature is important from the standpoint of quality of performance as well as safety. This is especially so if a toxic fluid or vapor Or one which need be recovered is used.
  • Another important feature the fluid treating apparatus must have is a means for avoiding or clearing plugged cells. Specifically, provision has to be made to remove any orifice for either cleaning or replacement while the adjacent positions are in operation.
  • an apparatus for fluid treatment of running lengths of yarn which comprises a vessel in which or through which a fluid may be passed preferably under elevated pressures and which contains a passageway which spans the vessel, directs the yarn through the vessel and exposes the yarn to the action of the fluid and, at any desired moment, protects the yarn from the fluid.
  • the passageway comprises an inlet mounted in one end of the vessel and extending into the vessel and into a cell passage called a cell tube, which is slidably mounted within the vessel.
  • the superimposed. relation between the extension and the cell tube permits control of the fluid along the edges of the tube extension into thecell tube.
  • the extension smooths out the flow of fluid and the cell tube may be moved forward to shut off the supply entirely.
  • an outlet Aligned with the cell tube and inlet tube is an outlet through which the yarn passes to a wind-up device. Since fluid is flowing through the vessel usually under pressure, there are means to keep the inlet and cell tubes stationed within the vessel and means to dispose of fluid coming out of the vessel through the inlet tube and the outlet.
  • the disposal means may be aspiration chambers and tubular inserts are provided to span these chambers.
  • the tubular insert at the outlet end cooperates with or is a suction device designed to draw the yarn through the passageway. Insertion of the suction device pushes the cell tube forward to closed position.
  • the apparatus comprises a pressure vessel fltted with inlet and outlet end plates, said inlet end plate containing a plurality of inlet tubes extending a short distance inside the pressure vessel, said outlet end plate containing a plurality of holes which hold, by sliding fit, outlet tubes which are Joined at one end of a plurality of cell tubes, said cell tubes and outlet tubes combined being capable of spanning the entire length of the vessel between the end plates and being capable of slight longitudinal movement whereby contact with the inlet tube is broken andfluid from the pressure vessel can enter the cell tubes and flow through these tubes. A portion will exit through the outlet tubes into an aspiration chamber at the outlet end and a portion will pass from the cell tube into the inlet tube and then to an aspiration chamber at the inlet end of the device.
  • Figure l is a perspective view partly in section of the inlet end of the device
  • Figure 2 is a perspective 'view partly in section of the outlet end of the device and Figure 3 is a sectional elevation showing the valving arrangement more clearly.
  • the pressure vessel called the cell body I is closed at each end by plates, the inlet end plate to the orifices.
  • the end plates are secured to the cell body I by means of the threaded bushings l.
  • the inlet end plate 2 is attached to an aspiration chamber 5 by means of bolts 6.
  • the outlet end plate 3 is attached to an outlet aspiration chamber I by bolts 6.
  • the inlet aspiration chamber 5 comprises plate 0 to which the inlet plate 2 is attached, the inlet guide block I and side plates Hi.
  • the outlet aspiration chamber I is composed of plate II to which outlet end plate I is attached, outlet guide block I! and side plates ll. Either the inlet or outlet guide blocks may be made in one piece or in section as shown in Figure 3.
  • Both aspiration chambers are equipped with flanges II which may be bolted at II to a frame (not shown) to secure the entire apparatus. Both aspiration chambers are open at one end and suction is applied at the other by any means, for example, a blower.
  • the inlet end and outlet end plates are carefully drilled on the same spacings and contain the inlet tubes II and outlet tubes l6, respectively.
  • the inlet tubes is are held in place by threading l1 in inlet plate 2 although other fastening means can be used.
  • the inlet tubes taper (7 included angle) down to a small tube II which extends into the interior of the cell body.
  • the outlet tubes 16 are mounted in holes in end plate 3 so that they may slide back and forth.
  • the tubes ii are secured to the individual cell tubes it.
  • tubes l6 and I! may be constructed in one piece. However, construction of the inward taper from both ends shown in tube It in Figure 3 is more conveniently done on a separate small tube.
  • Each cell tube II is externally tapered at the entrance end, the end fitting over extension is of the inlet tube II.
  • the cell tubes II are supported at the inlet end on guide plate 20 so that they are free to slide.
  • the cell tube support 20 is fastened to the inlet end plate 2 by means of bolts 2!.
  • the centering pins 22 and 23, shown in Figure 3, serve to position the end plates 2 and I with respect to the cell body I and to assure perfect alignment with one another.
  • the cell tubes II and the attached tubes it slide and are restrained from sliding out the outlet end by a shoulder formed by the smaller holes in the inner wall H of the outlet aspiration chamber 1. This shoulder may be seen at 35 in Figure 3.
  • the inlet tube I5 is so formed that it provides a seat 24 with the inlet end of cell tube I! shown in Figure 3.
  • contacts the inlet tube valve seat 24 and closes off the vapor passage into cell tube I l by forming joint 38.
  • the pressure holdoutlet Upon removal of the tubular insert or suction device, the cell tube falls by its own weight to open position.
  • the method of closing this vapor port and accomplishing string-up of the drawing apparatus is shown in Figure 3 in which the lower cell tube shown is in operating position and the upper is in shut-down or string-up position.
  • valve seat 38 When inlet tube I5 is removed, tube I3 moves up to and into plate 2 and a joint is formed between wall edges 32 of plate 2 and the tapered sides of IS, designated as valve seat 38.
  • This double valve arrangement is not essential; a single valve system may be used.
  • the wall edges 32 of inlet plate 2 may be recessed to receive the cell tube I9 and thereby form a seal in the presence or absence of inlet tube I5.
  • the double valve arrangement is preferred, since a worn valve seat on an inlet tube is easier to replace than a worn valve seat on the plate 2.
  • the string-up tool which may be used in stringing up the apparatus of this invention is equipped with a slender suction tube 25 which fits into the outlet aspiration chamber 1 and extends up against the outlet tube I6 as shown in Figure 3 at 31.
  • this suction device When this suction device is in place, the fluid port is closed and a strong suction is pro **d at the inlet tubes I5 and yarn may be drawn through the cell. Any string-up tool which will draw the yarn through the device may be used.
  • the bushings 28 are contained by inlet guide block 9 which also acts as the outer wall of the aspiration chamber 5.
  • the bushings 28 are held in place by any convenient means such as locking plate 29.
  • the locking plate 29 can be moved to disengage the bushings 28.
  • the tubular inserts 21 may be taken out and as described below inlet tubes I5 may be removed.
  • a tubular insert 21 is moved so as to enter an inlet tube I5
  • the yarn has a continuous path during string-up all the way through the entire cell and is subject to the drag of the air flowing through the cell into the suction device.
  • the tubular insert 21 is drawn out to its normal position set by the collar 3
  • a yarn end may be passed through the device without being exposed to the fluid. This is advantageous since for the most part, the fluids are hot and any softening of the yarn which would hamper string-up is avoided.
  • the extension of the inlet tubes into the cell tubes affords another advantage in that the flow of fluid to the yarn is smoothed out and turbulence is avoided.
  • an auxiliary seat is provided on the face of the inlet end plate 2 by the wall edges or unthreaded recess 32.
  • the inlet end of cell tube I9 is shaped at point 38 so as to form the mate to the auxiliary valve seat 32.
  • the double valve permits easy replacement of a plugged tube or a worn inlet tube valve seat. If it is necessary to remove a cell tube I8, outlet end plate and wall II may be removed and the tube may be withdrawn. In actual practice it is seldom necessary to remove a cell tube.
  • the yarn then runs into the suction device and the tubular insert 21 is drawn out to its normal position and the yarn is carried while traveling into the suction device over the output metering rolls and eventually to a suitable take-up device (not shown).
  • a suitable take-up device not shown.
  • the string-up of the device and changing of tubes can be performed by an operator with ease and safety.
  • An important element of safety is provided by the inlet and outlet aspiration cham bers 5 and 1.
  • Sufilcient suction is maintained in these aspiration chambers by means of blowers that substantially all of the fluid from the pressure vessel is carried away without issuing into the room or surrounding area. This is highly advantageous particularly if the treating material is toxic. The possibility of an operator receiving burns from the hot materials becomes very remote. In addition, the treating fluids may be recovered if desired.
  • the apparatus is not limited in use to any particular fluid. While steam is probably most commonly employed in commercial yarn processing, the treatment of yarns with more expensive-materlals is carried out advantageously in the apparatus of this invention. In addition to steam or water there may be mentioned air and other gases, formaldehyde vapor, bleaching solu tions, dyeing solutions, finishing solutions and such substances as alcohols, ketones, etc. in liquid or vapor form. In addition to the safety of operation, the treating fluid can be recovered without substantial loss. Further, the design is such that in the treatment of synthetic yarn at relatively high temperatures, if air has some degrading influence on the yarn at those high temperatures, it may be easily excluded.
  • the apparatus may also be used for the treatment of running lengths of yarn with liquids, particularly hot liquids.
  • the valvlng arrangement will operate equally well and the string-up can be accomplished in similar fashion to that described above.
  • the suction string-up device After the small amount of liquid in the cell tube is removed, the suction string-up device produces a flow of air through the cell tube which will carry the length of yarn through the tube.
  • the aspiration chambers at each end of the pressure chamber are used to carry away the treating liquid for purification and recycling.
  • the apparatus of this invention it is customary to use an individual cell tube for each running length of yarn to be treated, although this is no. necessary. While the pressure chamber may contain only one cell tube, it is generally advantageous to treat a pluralit of running lengths of yarn, in warp form or otherwise, simultaneously. In this way uniformity and economy are effected.
  • This apparatus is particularly adapted tothe handling of a plurality of running lengths of yarn on close centers. An arrangement comprising two parallel rows of cell tubes, those of one row being staggered with respect to those of the other has been found most eillcient for the handling of a pluraliy of running lengths of yarn.
  • the length of the cell .ubes and the corresponding size of the pressure chamber is not restricted in any manner.
  • the size is determined merely by the desired yarn treatment conditions. From the standpoint of economy and space conservation, the size of the apparatus will, or" course, be kep, to the minimum required by t .e processing conditions.
  • each running length of yarn receives individual treatment in its cell tube, the treatment of adjacent ends is uniform. This is made possible in the apparatus of this invention by the valving design.
  • Each valve is equidistant from the fluid source and variable pressures in adjacent cell tubes cannot exist.
  • the valve design is such that fluid turbulence in the cell tube is minimized. The fluid is admlt.ed to the cell tube through one end so that the flow is parallel to the wall of the tube and the tendency to spiral through the tube is eliminated.
  • the possibiliy for the formation and admittance of condensate in the individual cell tube is substantially eliminated by the design of the yarn treating apparatus of this invention.
  • the separation of condensate from vapor is made in the large volume part of the sys.em, namely, the pressure chamber, by means of outlet 33. Practically all of the condensate formed by steam or vapor entering inlet 34 is removed at 33.
  • the valves of the individual cell tubes are located such that condensate cannot be discharged in.o the tubes in slugs or large amounts.
  • the cell tubes are surrounded and heated by the hot treating vapor, This minimizes the tendency for formation of condensate inside the cell tubes.
  • the apparatus of this invention overcomes the objections inherent in. devices described in the prior art for fluid treatment of running lengths of yarn.
  • An apparatus has been provided which alaows uniform treatment of a multiple number of running yam ends on an individual basis so that string-up of one position while adjacent ends are running is devoid of danger and difiiculty.
