Definitions

  • This invention relates to an apparatus for drying thread or the like and, more particularly to an apparatus having a generally circular heated periphery over which the thread or the like is adapted to pass.
  • 'Zhread-dryihg reels are usually heated by fluids such as steam or hot water, hot oil or hot gases.
  • heating fluids are used in either open or clcmed type thread-drying devices.
  • the closed type of thread-drying device is preferable inasmuch as it is more economical, efilcient and safer to use.
  • drying devices are advantageous, they are not as efficient as they could bebecause the distances from their interior wherein the heating fluid circulates to the thread on the surface of the device are greater than desired, the distances causing certain heat losses. It is obvious, of course, that the longer the distance through which heat is transmitted the greater is the heat loss. If a predetermined temperature is to be maintained on the surface of the reel or of the drying device, then any heat lost because of distance through which the heat is transmitted must be compensated for by an increase in the temperature of the heating fluid or an increase in its circulation. Then, if the heat transfer distance of the reel is reduced to a practical minimum, the heat loss is materially reduced and the efiiciency of an internally heated reel is advantageously improved.
  • a thread -drying device such as a cantilever-type thread-storing, thread-advancing reel wherein the heating fluid circulates internally of the reel that there occurs a minimum loss of heat in its periphery in close proximity to the thread.
  • the drying reel is comprised of two sets of longitudinal tubular thread-bearing members positioned in an interdigitating relation through which the heating medium is continuously circulated.
  • Such a construction advantageously provides for a rapid transfer of heat, and a minimum loss of heat.
  • Figure 1 represents, in elevation, a cantilever type thread-storing, thread-advancing, drying reel
  • Figure 2 represents a cross section in elevation of the drying reel of Figure 1 as taken on line 2-42 of Figure 4.
  • Figure 3 isa section of Figure 1 taken along line 3-3;
  • Figure e is a section of Figure 1 taken along line i- 3.
  • the reel is formed of two generally cylindrical reel members i0 and i i.
  • Reel member it is mounted concentrically on shaft 62 to rotate therewith.
  • the reel member is formed of a plurality of longitudinal tubular thread-bearing members ll circular or of some other shape which are supported in end supports it and iii. The end supports it and is are, in turn, positioned on the shaft it, being frlctionally bound thereto through double seals Ell, M as will be hereinafter described, thus affixing the reel member id to the shaft 52.
  • the supporting member 69 is fitted to the shaft it upon which it is mounted and to which it is affixed by the binding seals 2%.
  • the front supporting member i8 is fitted to the shaft and irictionally bound thereto by the seals it.
  • a cap 23 is drawn against the front supporting member it by means of a threaded bolt 24 in the end of the shaft l2 forcing both of the seals 20 and 28, into the supporting members. Since the supporting members is and iii are concentric to r the shaft it, they support the thread-bearing members i? of the reel member it in a concentric manner about shaft H2.
  • the reel member I I periphery is also formed of a plurality of longitudinal tubular thread-bearing members 28 which are positioned in an interdigitating relation with the tubular thread-bear-' ing members I! of the reel member l0.
  • a pair of tubular bar members 28 advantagcousy comprise but one tubular member having a 180 bend at the unsupported end of the reel.
  • the members 28 are supported at one'end in the sealing rings 21, 28 of a flange 3
  • the ring provides the necessary rigidity required to that end of the reel member ii to offset the tension produced in the drying yarn or thread.
  • the sealing rings 21. 28 are attached to the flange 3
  • is adapted to rotate on a pair of antifriction roller bearings 33, 34 which are mounted on a generally circular eccentrically positioned member 35.
  • the eccentric member 36 positions the reel member I I in an askew and offset relation to the concentric reel member ID which relationship causes the two reel members when rotated to advance threads over their combined peripheries in a number of generally helical turns.
  • the eccentric reel member II is mounted on the eccentric to rotate thereon.
  • the concentric reel member by being fixed to the shaft [2 is therefore adapted to retate reel member I either through frictional bar contact or through a gear 38 fixed to the eccentric reel member flange 29 whose teeth bear against the radial sections forming the end supporting member IS.
  • the concentric reel member ill is adapted to be heated by circulating a heating fluid through the longitudinal tubular thread-bearing member IT.
  • the heating fluid is furnished to the members I through a shaft conduit 88, and shaft openings 38 which communicate with the radial passages of the rear supporting member l3.
  • the heating fluid is exhausted through passages 42 in the front supporting member
  • the thickness of the tubular members I! carrying the thread is the distance through which the heat from the circulating fluid is transmitted.
  • Reel member I is also composed of tubular thread-bearing members 28. These thread-bearing members terminate in and are supported in an annular ring 29 which is annularly indented and which with flange 3
  • the heating fluid then enters into one thread-bearing member 28 and returns through another such member into another annular chamber 41 formed by the complementary the radial conduits 5'! 5
  • the thread-bearing surface of the tubular. members l1 and 28 may be enlarged, if desired, by either flattening the tubular sections or cutting off some of the surface.
  • the shape of the bar members can be rectangular or of some other design providing, however, that the heating fluid passages are of sufficient size to providefor an adequate flow of a heating fluid.
  • the supporting ring 30 of reel member may. if desired, be hollow and the bar member 28 adapted to terminate therein.
  • connection rings 21, 29 The tubular members 28 are suitably sealed in the ring members 21, 29 and flange 3 IA as well as the adjacent annular manifolds or chambers 45 and 41 from themselves.
  • the annular manifold 45 is adapted to serve as a heating fluid supply source for passages 46 of the thread-bearing members 28 while manifold 51 is adapted to serve as an exhaust manifold.
  • the manifold 45 is supplied with heating fluid through radial conduits which communicate with an annular chamber 5
  • in turn communicates through passages 52 with a second interiorily formed chamber 54 formed by and between the eccentric member 35 and the shaft l2, and which chamber encompasses the heating fluid inlets 55 in the supply shaft l2.
  • the exhaust manifold 41 is emptied through with a cantilever type drying apparatus. It is not, however, to be considered as being limited thereto.
  • the invention can readily be embodied in .drying apparatuses that are supported from both ends.
  • the thread drying apparatus may be of the canted double roller type or the single roller type with assisting guides for effecting an advancement of thread.
  • heating fluids can be caused to circulate immediately adjacent their peripheries as, for instance, through an annular space made by concentric cylinders.
  • An apparatus for drying thread or the like comprising a reel embodying two intcrdigitatlng sets of hollow heating medium conducting thread-bearing members, said thread-bearing members serving as conduits for a heating medium adapted to flow therethrough, and a heating medium supplying and exhausting means for said hollow heating medium conducting thread bearing members.
