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.

Abstract
Description
- This invention relates to an apparatus for drying textile articles of manufacture, in particular textile yarn skeins.
- As is known in the textile industry, textile yarn skeins are usually dyed in special chamber into which the skeins are introduced from transport carriages.
- To support the skeins on the carriages, mutually adjoining rods are provided from which the skeins are suspended, and which bear with their opposed ends on guides provided on two opposite walls of a carriage. Upon completion of the dyeing operations, the carriages are withdrawn from the chambers and the skeins subjected to drying processes. For the drying step, an apparatus has been proposed which comprises essentially a reel or oearousel wheel set for rotation about a horizontal axis inside a housing. The rods are hooked to the reel periphery such as to lay parallel to the rotation axis thereof. The reel rotation creates a centrifugal force which forces the liquid out of the fibres. The centrifugal action is aided by the blowing of air into the housing.
- This prior apparatus has considerable drawbacks: first of all, transferring the skeins from a carriage to the reel and their removal have shown to be laborious and time-consuming operations. Furthermore, centrifugation creates overhelming problems of stability owing to the loaded skeins being somewhat unbalanced as the reel is started. Finally, air blowing has shown to be ineffective because the airflow, owing to the reel rotation, can only sweep the sideways outermost portions of the skeins.
- Thus 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.
- Within this task it is an object of the invention to provide such an apparatus which is simple and economical construction-wise and highly reliable in operation.
- The above task and objects are achieved by 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.
- Further features and advantages of this invention will be apparent from the following description of a preferred embodiment thereof, illustrated by way of example and not of limitation in the accompanying drawings, where:
- Figure 1 is a side elevation view of this apparatus;
- Figure 2 is a plan view of the apparatus of Figure 1;
- Figure 3 shows a view in elevation and in section along the line III-III of Figure 2;
- Figure 4 is a sectional view of the apparatus upper portion, taken in the plane of line IV-IV of Figure 2;
- Figure 5 is a plan view taken along the section line V-V of Figure 1;
- Figure 6 shows a view, in elevation and in section along the line VI-VI of Figure 5, also illustrating means effective to orient and load onto the apparatus a carriage loaded with yarn skeins; and
- Figure 7 is a detail plan view of the means for holding the carriages on the reel, taken along the line VII-VII of Figure 6.
- Making reference to the cited drawing figures, 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.
- Associated internally with the rings 10-12 is a
paneling 13, which extends along a complementary contour to said rings and delimits aperipheral chamber 14. The uprights 2-9 are located, with respect to the centre of theframework 1, at increasingly longer radial distances so that the paneling takes the form of a cylindrical surface coil. - The bottom ends of the
uprights uprights longitudinal stringers longitudinal stringers longitudinal stringers - In a similar manner, the tops of the
uprights uprights parallel beams beams uprights connective elements beams horizontal portions 19a, 20a of the same. - From the meeting points between the
beams arms central ring 29 of square shape. Expediently, the uprights, longitudinal stringers, beams, coupling elements, as cited hereinabove, and thering 29 are constructed from tubular members of rectangular cross-section. - The
chamber 14 is closed at the top by a deck orcover 30, which delimits centrally aport 31, and peripherally is connected to the top edge of thepaneling 13. Thepaneling 13 and cover 30 form the apparatus housing. Theport 31 communicates upwardly to aconduit 32 defined by a hood member generally indicated at 33. The hood comprises twohorizontal panels portion 19a of thebeam 19 and thearms beam 20 and thearms vertical panels portions 19a and 20a and thecover 30, and lastly aslanting panel 38 which extends laterally between the slanting edges of thevertical panels ring 29 andcover 30, respectively. At an opposite location to thepanel 38, thepanels additional panel 39, which extends between thearms port 40, which through saidconduit 32 communicates to theaccess port 31 of thechamber 14. - The framework described hereinabove bears onto a
bed 41, to which it is secured by means ofanchor bolts 42. It should be noted that thebed 41 acts as the bottom for the housing formed by thepaneling 13 andcover 30, and has achannel 43 for collecting the liquid issueing from the articles of manufacture, as will be explained more clearly hereinafter. - On the
upper ring 29 and at the point of intersection of a cross located in the central square formed by the longitudinal stringers 15-18, there are arrangedsupports 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 arms 49a,50a, arranged mutually perpendicular and to extend radially from theshaft 47. with which they are made to rotate integrally. - To the ends of the
arms 49a, 50a, there are attached two respectivesuperimposed frames - More specifically, 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, thelongitudinal stringers longitudinal stringers parallel arms 53a,54a; 53b,54b; 55a,56a; and 55b,56b. The ends of each arm pair are interconnected by arod 57, whilst the ends of the arms in adjacent pairs . are interconnected byrods 58. - Secured on the
arms 53a-56b areguides 59, each comprising an upwardly open channel sectional member. Theguides 59 of each arm pair are parallel to each other and aligned onshanks 60 protruding radially out of the arm ends. Theupper frame 51 of the reel has an entirely similar construction to thelower frame 52, excepting for theguides 59 andshanks 60. Moreover, the upper frame is exactly superimposed on the lower frame, to which it is connected byaxial uprights 61 which interconnect the intersection points of thelongitudinal stringers longitudinal stringers outer uprights 62 which interconnect the ends of the longitudinal stringers together. - As may be gathered from Figure 5, the
reel 48 configures the rotor of a centrifugal fan, in which air is admitted axially through theport 31 in thecover 30. The outlet of said fan, indicated at 63, is located tangentially to thepaneling 13 where the latter, owing to its coil pattern, is at a greater distance from the reeel periphery. The pairs of parallel arms of thelower 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 ofwings 64, which can be opened outwardly and are hinged to theuprights chamber 14 through an additional door in the paneling, offset by 900 with respect to the former and being also composed of a pair ofwings 65 which can be opened outwardly and are hinged to theuprights 4,5. The opening of thewings longitudinal walls 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 thewall 69. The top and bottom edges of the walls 67-69 are fastened tostiffening frames 70,71 of rectangular perimeter. Along the upper portions of thewalls sectional members channels 74 in whichquadrangular blocks 75 can slide. With theblocks 75, there are associated the opposed ends ofrods 76, from which skeins M to be dried are suspended. Therods 76 with the skeins are introduced into thechannels 74 from the carriage side opposite to thewall 69, such that the blocks are close behind one another. Therods 76 are locked by means ofpins 77 being inserted into holes in the sectional members 72-73, which intercept the sliding movement of the blocks along theguides 74.. - Each
carriage 66 has pairs ofrunning wheels 78,79 by means whereof it can be transferred from the dyeing chambers to a transport carriage and hence to a tippler. In fact, the carriage, for introduction into the apparatus, is previously tilted through 90°, so that it bears onto thewheel pair 78 and anadditional wheel pair 80 supported close to the carriage top edge. of the carriage.. - To tip the carriage over, a tippler is provided, generally indicated at 81, which is arranged in front of the
door 64. Said tippler comprises asupport 82 composed of a pair ofbrackets 82a made rigid, to form a right angle, with an additional pair. ofbrackets 82b. Thebrackets 82a lay on the same plane as thebrackets 82b and are at a mutual distance apart which is equal to that of the pairs ofarms 53a-56b. To the inner faces of thebrackets guides sectional members 59 and adapted to receivewheels - The
support 82 is hinged to apin 85 of amolding 86 secured to the base 41 in front of thedoor 64 and has aflange 87 to which is particularly connected the rod of a fluid-dynamic jack 88 the cylinder whereof is articulated to themolding 86. By means of thejack 88,thesupport 82 is enabled to perform a 900 oscillation to move from a position where thebrackets 82a are horizontal to receive a carriage into another position where the carriage weight is transferred onto thebrackets 82b. During this oscillation the ends of thebrackets 82b enter thechamber 14 through theopen door 64 and bear against theshanks 60. Expediently, the ends of thearms 82b are of a yoke-like configuration, such as to hook onto theshanks 60 to ensure alignment of theguides 84 with theguides 59 of thearms 53a-56b and allow transfer of the carriage from thesupport 82 into thereel 48. The transfer is effected by thrust even though it is possible to provide automatic actuating means. - As the
carriage 66 is inserted into the respective seat on thereel 48, the holding members prevent the same from being thrown outwards by centrifugal force during the rotation of thereel 48. Such members comprise, for each seat, twobars supports 91 of theframes - Rotatively rigid with the
bars armed levers levers respective sliders sleeves arms 53a-56b. The sliders are parallel to thearms 53a-56b, and their opposed ends to those of engagement with thelevers rods 57 and are arranged on the sides of theshanks 60. Such ends are also provided with idle rollers 100,101. The other arms of thelevers 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 asmall bridge member 103. Owing to the effect of thesprings 102, thebars hooks walls sliders springs 102. The displacement of the sliders is accomplished by means of specially providedcams 104 which are mounted on the ends of thebrackets 82b of thetoppler 81 and adapted to act on the sliders upon thebrackets 82b being tilted into the position shown in Figure 6. - Expediently, at the
door 65, there is provided a similar toppler which, during the apparatus loading and unloading steps, for each carriage being introduced into thechamber 14 through thedoor 64, allows one carriage to be withdrawn from that same chamber. - The apparatus described hereinabove operates as follows.
- .First, the carriages are loaded onto the
reel 48. For this purpose, thesupport 82 will occupy the position shown in dash-and-dot lines in Figure 6, with thebracket pair 82a laying horizontal to receive a carriage from the dyeing stations. The carriage, during the transfer operation, runs with thewheels 78,79 along theguides 83 and its orientation on thesupport 82 is selected such that thecross wall 69 is adjacent thebrackets 82b. With the carriage positioned on thesupport 82, thewheels guides 84. Up to this time, the skeins are held hanging loose from therods 76. - After opening the
door 64, thejack 88 is actuated which produces a 90° rotation of thesupport 82. During this rotation, the skeins M will pile up one upon another against thewall 69 which has taken a horizontal lay. Thebrackets 82b are moved with their free ends into thechamber 14, where they will hook themselves onto theshanks 60 to ensure alignment of theguides 84 with theguides 59 of theframe 52. At the same time, under the effect of the citedcams 104, thehooks wheels guides reel 48. Upon reaching said seat, thetoppler 81 is moved back into its starting position to receive a fresh carriage. However, the lifting of thebrackets 82b causes thecams 104 to disengage from the rollers 100,101 of thesliders hooks springs 102, to pivot and hook onto thewalls - Now the
reel 48 is rotated through 900 to bring a fresh seat opposite thedoor 64 and effect the loading of a fresh carriage. The above-described operations are repeated until all the reel seats are occupied. - At this time, after closing the
door 64, 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, thecarriage walls port 40,conduit 32 andport 31, and discharges it tangentially through theport 63. - The intake air is conveyed between the
walls - The liquid removed by evaporation is conveyed through the
port 63, whereas that ejected by centrifugation, after flowing down the inside surface of thepaneling 13, is collected into thechannel 43 in the bed and removed. - 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. - It will be recognized that the apparatus fully achieves the invention objects. In particular, 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. Furthermore, 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. In addition thereto, 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 thechamber 14. - In practicing the invention, the apparatus shape and dimensions may be varied to meet individual requirements.
- Moreover, the technical details may be replaced with other equivalent ones.
