Definitions

  • This invention relates to an apparatus for drying textile articles of manufacture, in particular textile yarn skeins.
  • textile yarn skeins are usually dyed in special chamber into which the skeins are introduced from transport carriages.
  • the task of the present invention is to provide a novel apparatus which can obviate the drawbacks of conventional apparatus,particularly by facilitating the loading steps and making the drying step faster and more effective, without inducing, however, matting or otherwise damaging the yarns.
  • an apparatus for drying textile articles of manufacture in particular textile yarn skeins, characterised in that it comprises a chamber defined by a vertical cylindrical coil-shaped housing having a top drying air inlet port and a tangential drying air outlet port, at least one port for introducing and withdrawing into/from said chamber carriages carrying articles of manufacture to be dried, a reel carried rotatably within said chamber and having a plurality of angularly distributed seats for accommodating respective carriages, and means of orienting the carriages in said seats such that the articles of manufacture are caused to take, as the reel is being rotated, a perpendicular orientation to the rotation axis.
  • this apparatus comprises an outer framework, generally indicated at 1 and-including a series of eight uprights 2-9 arranged essentially at the vertices of a octagon and being interconnected by three polygonal pattern rings, 10,11 and 12.
  • a paneling 13 which extends along a complementary contour to said rings and delimits a peripheral chamber 14.
  • the uprights 2-9 are located, with respect to the centre of the framework 1, at increasingly longer radial distances so that the paneling takes the form of a cylindrical surface coil.
  • the bottom ends of the uprights 2,3,4,5 are respectively connected to those of the uprights 7,6,9,8 by longitudinal stringers 15,16,17,18 laid parallel in pairs.
  • the longitudinal stringers 15,16 moreover, are perpendicular to the longitudinal stringers 17,18, so as to form a double cross pattern.
  • tops of the uprights 2,3 are respectively connected to the tops of the uprights 7,6 by a pair of mutually parallel beams 19,20 in the pattern of a flattened trapezium, as is more clearly shown in Figures 1 and 4.
  • the beams 19,20 are joined to the uprights 8,9 and 4,5 by connective elements 21, 22,23,24 whichtfrom the tops of said uprights,extend obliquely to the corner points defined by the slanting portions of the beams 19,20 with the horizontal portions 19a, 20a of the same.
  • the uprights, longitudinal stringers, beams, coupling elements, as cited hereinabove, and the ring 29 are constructed from tubular members of rectangular cross-section.
  • the chamber 14 is closed at the top by a deck or cover 30, which delimits centrally a port 31, and peripherally is connected to the top edge of the paneling 13.
  • the paneling 13 and cover 30 form the apparatus housing.
  • the port 31 communicates upwardly to a conduit 32 defined by a hood member generally indicated at 33.
  • the hood comprises two horizontal panels 34,35, which close the areas defined between the portion 19a of the beam 19 and the arms 25,26, and between the portion 20a of the beam 20 and the arms 27,28, as well as two vertical panels 36,37 which close the areas between the portions 19a and 20a and the cover 30, and lastly a slanting panel 38 which extends laterally between the slanting edges of the vertical panels 36,37 and is rigid at the bottom with the ring 29 and cover 30, respectively.
  • the panels 36,37 and an additional panel 39 which extends between the arms 25,28, define a port 40, which through said conduit 32 communicates to the access port 31 of the chamber 14.
  • the framework described hereinabove bears onto a bed 41, to which it is secured by means of anchor bolts 42.
  • the bed 41 acts as the bottom for the housing formed by the paneling 13 and cover 30, and has a channel 43 for collecting the liquid issueing from the articles of manufacture, as will be explained more clearly hereinafter.
  • supports 45 and 46 for the shaft 47 of a reel or carousel wheel generally indicated at 48 and set for rotation about a vertical axis.
  • the reel comprises two crosses 49,50, each of which is composed of four arms 49a,50a, arranged mutually perpendicular and to extend radially from the shaft 47. with which they are made to rotate integrally.
  • the frame 52 includes four longitudinal stringers 53-56 which, similarly to what has been specified above for the longitudinal stringers 15-18, are arranged parallel in pairs, the longitudinal stringers 53,54 being also perpendicular to the longitudinal stringers 55,56.
  • the longitudinal stringers 53,54 being also perpendicular to the longitudinal stringers 55,56.
  • the ends of each arm pair are interconnected by a rod 57, whilst the ends of the arms in adjacent pairs . are interconnected by rods 58.
  • guides 59 Secured on the arms 53a-56b are guides 59, each comprising an upwardly open channel sectional member.
  • the guides 59 of each arm pair are parallel to each other and aligned on shanks 60 protruding radially out of the arm ends.
  • the upper frame 51 of the reel has an entirely similar construction to the lower frame 52, excepting for the guides 59 and shanks 60.
  • the upper frame is exactly superimposed on the lower frame, to which it is connected by axial uprights 61 which interconnect the intersection points of the longitudinal stringers 53,54 with the longitudinal stringers 55,56, and by axial outer uprights 62 which interconnect the ends of the longitudinal stringers together.
  • the reel 48 configures the rotor of a centrifugal fan, in which air is admitted axially through the port 31 in the cover 30.
  • the outlet of said fan indicated at 63, is located tangentially to the paneling 13 where the latter, owing to its coil pattern, is at a greater distance from the reeel periphery.
  • the pairs of parallel arms of the lower frame 52 identify, with a pair of parallel arms in the upper frame,; seats wherein carriages loaded with skeins to be dried are inserted.
  • the carriages are introdiced into such seats through a door in the paneling which comprises a pair of wings 64, which can be opened outwardly and are hinged to the uprights 2 and 3.
  • the carriages move out of the chamber 14 through an additional door in the paneling, offset by 90 0 with respect to the former and being also composed of a pair of wings 65 which can be opened outwardly and are hinged to the uprights 4,5.
  • the opening of the wings 64,65 can be automated in accordance with the drying cycle program.
  • Each carriage (see Figure 6, where it is indicated at 66) has a parallelepipedal shape with two longitudinal walls 67,68 connected on one side to a cross wall 69, such as to take a U-like shape, that is one open at the top and bottom and on the opposed side to the wall 69.
  • the top and bottom edges of the walls 67-69 are fastened to stiffening frames 70,71 of rectangular perimeter.
  • Each carriage 66 has pairs of running wheels 78,79 by means whereof it can be transferred from the dyeing chambers to a transport carriage and hence to a tippler.
  • the carriage for introduction into the apparatus, is previously tilted through 90°, so that it bears onto the wheel pair 78 and an additional wheel pair 80 supported close to the carriage top edge. of the carriage..
  • a tippler is provided, generally indicated at 81, which is arranged in front of the door 64.
  • Said tippler comprises a support 82 composed of a pair of brackets 82a made rigid, to form a right angle, with an additional pair. of brackets 82b.
  • the brackets 82a lay on the same plane as the brackets 82b and are at a mutual distance apart which is equal to that of the pairs of arms 53a-56b.
  • guides 83,84 comprising channel members similar to the previously cited sectional members 59 and adapted to receive wheels 78,79 and 80.
  • the support 82 is hinged to a pin 85 of a molding 86 secured to the base 41 in front of the door 64 and has a flange 87 to which is particularly connected the rod of a fluid-dynamic jack 88 the cylinder whereof is articulated to the molding 86.
  • the support 82 is enabled to perform a 90 0 oscillation to move from a position where the brackets 82a are horizontal to receive a carriage into another position where the carriage weight is transferred onto the brackets 82b. During this oscillation the ends of the brackets 82b enter the chamber 14 through the open door 64 and bear against the shanks 60.
  • the ends of the arms 82b are of a yoke-like configuration, such as to hook onto the shanks 60 to ensure alignment of the guides 84 with the guides 59 of the arms 53a-56b and allow transfer of the carriage from the support 82 into the reel 48.
  • the transfer is effected by thrust even though it is possible to provide automatic actuating means.
  • the holding members prevent the same from being thrown outwards by centrifugal force during the rotation of the reel 48.
  • Such members comprise, for each seat, two bars 89,90 which are vertical (see Figures 6 and 7) and rotatable in supports 91 of the frames 51,52.
  • Rotatively rigid with the bars 89,90 are respective hook pairs 92,93 and two-armed levers 94,95. With one arm of the levers 94,95 there engage respective sliders 96,97 which are guided slidably in sleeves 98,99 rigid with the arms 53a-56b.
  • the sliders are parallel to the arms 53a-56b, and their opposed ends to those of engagement with the levers 94,95 protrude outwards with respect to the rods 57 and are arranged on the sides of the shanks 60. Such ends are also provided with idle rollers 100,101.
  • the other arms of the levers 94,95 penetrate the cavities of the arms 53a-56b and have springs 102 (in Figure 7 the one relating to the arm 54a is shown) hooked thereto which extend inside the cited arms to be anchored to a small bridge member 103.
  • the bars 89,90 are rotated such that the hooks 92,93 are caused to project toward the inside of the carriage housing seats to hook onto the lower edges of the walls 67,68 after their upsetting.
  • the sliders 96,97 are acted upon to force the hooks open against the bias of the springs 102.
  • cams 104 which are mounted on the ends of the brackets 82b of the toppler 81 and adapted to act on the sliders upon the brackets 82b being tilted into the position shown in Figure 6.
  • the carriages are loaded onto the reel 48.
  • the support 82 will occupy the position shown in dash-and-dot lines in Figure 6, with the bracket pair 82a laying horizontal to receive a carriage from the dyeing stations.
  • the carriage runs with the wheels 78,79 along the guides 83 and its orientation on the support 82 is selected such that the cross wall 69 is adjacent the brackets 82b.
  • the wheels 78,80 engage with the guides 84. Up to this time, the skeins are held hanging loose from the rods 76.
  • the jack 88 is actuated which produces a 90° rotation of the support 82.
  • the skeins M will pile up one upon another against the wall 69 which has taken a horizontal la y .
  • the brackets 82b are moved with their free ends into the chamber 14, where they will hook themselves onto the shanks 60 to ensure alignment of the guides 84 with the guides 59 of the frame 52.
  • the hooks 92,93 are opened, so that the carriage, by rolling on the wheels 78,80 along the guides 74,59, can be pushed into its respective seat on the reel 48.
  • the toppler 81 Upon reaching said seat, the toppler 81 is moved back into its starting position to receive a fresh carriage. However, the lifting of the brackets 82b causes the cams 104 to disengage from the rollers 100,101 of the sliders 96,97, so that the latter are made free to slide outwards and allow the hooks 92,93, under the action of the springs 102, to pivot and hook onto the walls 67,68, which will be engaged at their bottom edges, which edges, upon toppling over, have taken a vertical attitude.
  • the drying step proper is initiated by rotating the reel through a drive motor installed on the apparatus and not shown in the drawings. Owing to the rotational movement, the carriage walls 67,68 will behave as the blades of an impeller which draws in air axially from the outside through the port 40, conduit 32 and port 31, and discharges it tangentially through the port 63.
  • the intake air is conveyed between the walls 67, 68 of the various carriages and flows through the gaps delimited by the overlapping layers of skeins, which owing to the centrifugal force effect, are thrown outwards and take accordingly a practically horizontal attitude.
  • the skeins will be dried both by virtue of the cited centrifugal action and of the evaporation effect as enhanced by the air sweeping the skeins themselves.
  • the liquid removed by evaporation is conveyed through the port 63, whereas that ejected by centrifugation, after flowing down the inside surface of the paneling 13, is collected into the channel 43 in the bed and removed.
  • the treated carriages Upon completion of the drying operation, and after stopping the reel, the treated carriages are replaced with others filled with fresh skeins to be dried. Expediently, the treated carriages are removed through the door 65, with which there is associated, as specified above, a toppler quite similar to the one indicated at 81. This expedient permits, for each carriage removed, the introduction of another into the apparatus.
  • the apparatus fully achieves the invention objects.
  • the centrifugal fan design of the apparatus enables full exploitation of the combined effects of centrifugal force and ventilation, thereby reducing the drying times to a considerable extent.
  • the particular construction of the carriages requires no removal of the skein supporting rods, as is instead required with conventional apparatus, with the result that the overall processing time can be greatly shortened.
  • the operators are no longer exposed to contact with the chemicals to which the skeins are subjected in the course of the dyeing process.
  • the invention is susceptible to many modifications and variations without departing from its protective scope.
  • One of these may be the provision of a heating battery located before the inlet 40, through which the ventilation air can be heated prior to its admission into the chamber 14.
  • the apparatus shape and dimensions may be varied to meet individual requirements.
