Definitions

  • the invention relates to a bobbin for dyeing and bleaching machines according to the preamble of claim 1.
  • Such a coil carrier is known from FR-A-794064, in which coil carrier the carriers for the individual coils are arranged on the outside of the cylindrical wall.
  • Such an arrangement of the supports for the bobbins leads to poor utilization of the space available within the boiler of the dyeing or bleaching machine and the formation of a considerable dead space, as a result of which the liquor ratio becomes large and the known disadvantageous consequences of dyeing technology, more energy and economic in nature.
  • such a coil carrier with coils arranged on its outside is poorly suited for use in drying processes following the dyeing process by spinning, since the holding means of the coils on the carriers are fully exposed to the centrifugal force and would therefore have to be oversized in order to loosen and spin off the coils to prevent from their carriers.
  • Coil carriers of the type known from FR-A-794064 could not prevail in practice for the above reasons, so that other solutions were sought.
  • DE-A-2555974 shows a type of coil former that is still used almost universally today.
  • These are material carriers, consisting of a base plate, an upper plate and a number of coil columns each surrounded by a tubular cylinder. The coil columns are arranged perpendicular to circles concentric to a central tube between the horizontal base plate and the upper plate parallel to this.
  • the bobbins are usually placed one after the other on bobbin spindles, a separating plate being arranged between every two bobbins, and the row of bobbins being fixed on each bobbin spindle with the aid of a spring plug.
  • the loading and unloading of the bobbins therefore requires a considerable amount of time.
  • the object of the invention is to provide a bobbin for dyeing and bleaching machines which allows the best possible use of the interior of the boiler of the machine while keeping the liquor ratio low, is quick and easy to load and unload with bobbins, have large cross-sectional areas of the fleet and can be easily spun is.
  • the bobbin generally designated 10 can be seen inserted into a dyeing machine, which essentially consists of a cylindrical vertical kettle 11 with a tightly closing lid 12, on the bottom of which a pressure and a return line 13 or 14 of a circulation pump 15 are connected, which is mutually operable.
  • the lines 13, 14 open via concentric pipe connections 16, 17 into the boiler 11, the first of which ends at a central ring support 18, while the second is connected to the bottom of the boiler, where a heating coil 19 is arranged for heating the liquor.
  • a vertical column 20 extends from the center of the ring support 18 and serves to fix the coil support 10 inside the boiler 11.
  • the coil carrier consists of three superposed units 10A, 10B, 10C, which are identical to one another, so that only one of them needs to be described.
  • the unit is formed by a cylindrical impermeable ring wall 21, which ends at the bottom with a profiled ring 22 and at the top with an annular support guide 23.
  • one unit can be arranged above another, the ring 22 of the upper unit engaging in the annular support guide 23 of the unit underneath, thereby representing a good liquid seal.
  • means (not shown) for mutual coupling of units placed one above the other, for example in the form of a bayonet lock, can also be provided.
  • the cylindrical impermeable ring wall 21 of each unit is provided on its inside with a plurality of supports 24 for one coil each, which are described in more detail below with reference to FIGS. 4-7.
  • These carriers 24 project radially inward from the cylindrical ring wall 21 and are arranged at appropriate mutual distances on circles in superimposed levels (three levels per unit in the illustrated case).
  • each carrier 24 is intended to receive a single coil 25 and its shape is adapted to that of the coil (in the case shown it is conical coils, but it could also be cylindrical coils).
  • the carrier consists of a central part 26 with four radial ribs 27, the outer wall of which lies on a conical surface with an axis which coincides with that of the central part 26.
  • the ribs 27 connect the central part 26 to a tubular body 28, which is provided with a disk-shaped plate 29, in which through holes 30 are provided.
  • This plate 29 can be corrugated in the circumferential direction.
  • the tubular body 28 has an annular groove 31, into which the bottom of the sleeve 32 of the coil 25 can be inserted. The sleeve is perforated over the entire length on which the yarn 33 is wound on it.
  • a handle 35 is arranged on the head 34 to hold an attached coil 25. This is rotatable about a pin 36 which is attached to the head off-center to the axis of the handle and the head. This pin 36 penetrates into a recess in the handle 35, in which a spring 37 is arranged, which tries to hold the base surface of the handle against the head 34. In the base surface of the handle 35, a circular sector-shaped groove 38 is excluded, which in the rotated position of the handle 35 (see FIG. 6) engages with the free edge of the sleeve 32 of the coil 25 plugged onto the carrier 24 and thus holds the coil on the carrier . If, on the other hand, the handle 35 is in the same axis position as the head 34 (see FIG. 5), then it allows the coil 25 to be plugged in or removed.
  • the tubular body 28 has a support shoulder 39 and is inserted from the inside into a corresponding hole 40 in the cylindrical ring wall 21 in order to be fastened by means of a nut 41 and washer 42.
  • the carrier 24 arranged on the inside of the wall 21 is axially connected to the outside of the wall for the passage of the liquor in one direction or the other. If, for example, the liquor enters the carrier 24 through the tubular body 28, then, given the presence of the sealing head 34, it cannot continue to flow in the axial direction and must therefore flow through the sleeve 32 and the yarn 33 wound thereon in the radial direction.
  • the coil carrier 10 consisting of the three units 10A, 10B, and 10C stands on a base plate (see FIG. 1); in particular, the lowermost unit 10C engages with its profiled ring 22 in an annular support guide 51, with which the base plate is provided, and can also be anchored to this by suitable means.
  • the base plate 50 in turn lies in a liquid-tight manner on the central ring support 18, which has a central opening 52 through which the ring support 18 is connected to the connection 16 of the line 24.
  • a cylindrical displacement body 53 is fastened to the base plate 50 and has an axial opening in the middle, by means of which it is attached to the central column 20.
  • the displacement body 53 has the task of reducing the amount of liquor and it takes up practically the entire space within the carrier 24 for the coils.
  • a perforated cylindrical wall 54 is provided at the bottom of the displacement body 53, through which the space of the pressure vessel in which the coil carrier 10 is arranged communicates with the central opening 52 of the base plate 50.
  • a cover 55 which is clamped by means of a wing nut 56, is arranged above the bobbin 10 and seals against this by engagement of a profiled ring 57 attached to it in the annular support guide 23 of the uppermost unit 10A.
  • the circulation of the paint liquor takes place in a sense (arrow 60 in FIG. 1) from the line 13 and the connection 17 through the gap 58 between the wall 21 of the units 10A, 10B, 10C and that of the boiler 11, then through the carrier 24 Coils 25 with a uniform flow through them in the position plugged onto the carrier, then through the perforated wall 54 to the connection 16 and into the line 14.
  • the liquor flows in the opposite direction.
  • FIG. 8 An embodiment variant of the coil carrier is shown in FIG. 8, in which parts which correspond to those of the previously described embodiments are identified by the same reference numerals, but increased by 100.
  • the coil carrier 110 is double-walled instead of single-walled.
  • a second cylindrical impermeable ring wall 170 is arranged concentrically around the cylindrical impermeable ring wall 121 of each unit 110A, 110B and 110C, which supports the spools for the spools and which has a space 171 with the first and a space with the wall of the pressure vessel 111 158 forms.
  • the base plate 150 is hollow and its cavity 172 communicates with the intermediate space 171 and with the central opening 152 of the plate itself, which in turn is connected to the connection 116 of the line 114 through the support 118.
  • the cover 155 is closed only in the central region, and radial ribs 173 protrude from it in the manner of a radial ring, which at its ends carry the profiled ring 157, which engages sealingly between the upper ends of the two concentric walls 121 and 170 of the upper coil support unit 110A.
  • the gap 158 is below the boiler floor in which the heating coil 119 is arranged, with the connection 117 and above the openings between the ribs 173 with the space between the displacer 153 and the wall 121, in which the carrier 124 for the Coils are connected.
  • connection between the different stacked units of the bobbin 110 is made in this embodiment by simply engaging the upper and lower ends of the ring walls 121 and 170 of the units.
  • FIG. 9-11 Another embodiment of the bobbin is shown in Figures 9-11.
  • FIG. 9-11 the parts which correspond to those of the embodiment according to FIG. 8 are identified by the same reference numerals, but increased by 100 more. Furthermore, the parts relating to the outer coil carrier are identified by the index “I” and the parts relating to the inner coil carrier are identified by the index “II”.
  • a double coil carrier 210 I and 210 II is introduced into the pressure vessel 211, which consists of two concentric groups of identical coil carrier units 210A I, 210B and 210C I or 210A II, 210B II and 210C II placed one above the other.
  • Each unit has a double impermeable wall 221 and 270 or 221 11 and 270 II with a corresponding space 271 I or 271 II, the radial supports 224 I and 224 II being attached to the coils on the inner wall.
  • the coil carrier could also be formed from more than two concentric groups of stacked carrier units.
  • the loading and unloading of the ring-shaped carrier units can be carried out very simply and quickly, since it is only a matter of attaching or removing a single spool of thread per carrier without the need for separating plates or the like, the spool on the carrier in question is held with the help of a quick release fastener, which, however, does not necessarily have to have the structure described.
  • a significant economic-organizational advantage is that the bobbin can be disassembled quickly by removing the identical carrier units from the base plate and there is the possibility of reusing the latter immediately for a new dyeing process, provided, of course, that a certain number of Carrier units as equipment that can be used independently in other work phases, such as loading with the material to be colored, spinning and drying the colored material.
  • the passage cross-section available per kg for dye liquor is at least ten times larger than that of known coil carriers, since each coil is acted upon directly and independently of the others with liquor.
  • the dye liquor passes through the yarn at a slower speed so that it is treated more gently.
  • a very significant advantage is that the ring-shaped carrier units are excellent to spin, since the yarn spools are all arranged on the same diameter.
  • the carrier units can thus be loaded together with the dyed yarn packages from the dyeing machine and used directly in spinning devices without any intermediate handling.
  • the horizontal arrangement of the treated coils means that they do not suffer any harmful deformations in the subsequent processing.
  • the bobbin After spinning, the bobbin can be transferred to the drying device on suitable trolleys.
  • the use of the bobbin in high-speed dryers also has the advantage of absolute uniformity of drying after all yarn bobbins are in the same working conditions.
  • the construction of the coil carrier is extremely simple, without the need for separating plates, plugs and the like.
  • the carriers for the individual coils which can advantageously be made of plastic, are easily interchangeable in some cases.
  • the coil carriers according to the invention in machines up to a certain diameter, also achieve a reduction in the liquor ratio in the order of 20-30%, which is due to the reduction in energy, water, steam, Additive consumption, as well as the environmentally harmful outflows and working hours corresponds to a reduction in costs and increased colorability thanks to the increase in color cycles.
  • the bobbin carrier according to the invention in particular in the case of dyeing machines with a small diameter, allows the liquor ratio to be maintained virtually unchanged even in the case of the use of large diameter bobbins.
  • cylindrical ring wall used in the description and in the claims should not be interpreted as being limited to a circular cylindrical wall, that is to say a wall with a circular cross-section, but that this expression is to be applied in general :
  • the cross section of the wall could therefore also be polygonal or wavy, for example.
  • the coil carrier with a double cylindrical ring wall and associated annular space
  • the single or double ring wall of the bobbin carries the carriers for the bobbins on the inside in a radial arrangement, with a single bobbin on each of the radial carriers and with the bobbins in a center-symmetrical arrangement in each Cross-sectional plane of the wall to allow skidding in a fully balanced condition.
