Definitions

  • the invention relates to a device for drying a running sheet of thread wetted with size or dye, in which the optionally divided thread sheet is wetted and squeezed, then fed to a pre-dryer consisting of heating cylinders arranged in pairs and finally optionally dried after reunification.
  • a pre-dryer consisting of heating cylinders arranged in pairs and finally optionally dried after reunification.
  • wetting with sizing or dye means any type of application, e.g. Soaking or spraying, the liquid substance to be dried then understood.
  • a dryer in which the thread sheet is impregnated after a two-fold division and after the impregnation following a squeezing unit is divided again twice, i.e. a dryer with a four-fold division and two wetting points, in particular with two the size or the trough containing the dye with a subsequent squeezing mechanism has been introduced in practice.
  • a corresponding arrangement is described in DE-A 32 02 923.
  • two pairs of heating cylinders lie vertically one above the other in two approximately horizontal planes.
  • the thread sections are fed to the cylinders along a plane lying between the two pairs of heating cylinders. This results in an approx. 2 m long path between the crushing unit and the first contact with a heating cylinder.
  • the conventional dryers of the relevant type ultimately work with a four-fold division in the pre-dryer area, but the thread sheet must be divided a first time before wetting or soaking, so that two wetting points with squeezing mechanism are required.
  • a fourfold division between the squeezing mechanism and predrying would only increase the aforementioned space and bleaching problems in the prior art devices.
  • the invention has for its object to provide a dryer for four-fold division in the pre-dryer area so that with a substantially symmetrical guidance of the thread sections between the exit of the squeeze mechanism and the first emergence on a pre-dryer in a compact and low design with a minimal short distance in the directly after the squeeze unit is possible.
  • the arrangement should allow an extension of the final dryer or the interposition of additional drying cylinders.
  • the solution according to the invention for the device mentioned at the outset is that the heating cylinder pairs are in the same horizontal or vertical plane and the individual heating cylinders are located horizontally next to one another above the squeezing mechanism and vertically one above the other at the outlet of the squeezing mechanism, symmetrically with respect to a diagonal of the above-mentioned horizontals and Vertical are stored and that the outlet of the squeezing mechanism lies in the gusset spanned by the horizontal and vertical between the pairs of heating cylinders on the diagonal.
  • the thread coulter is divided after wetting following a squeeze mechanism, each partial thread coulter thus formed is fed to a separate pre-dryer containing two heating cylinders, and the pre-dried partial thread coulters are reunited for the final drying.
  • the invention first enables largely symmetrical guidance of the thread sections with a minimally short distance in the wet field, because the heating cylinder pairs quasi around the squeeze mechanism on the Outlet side can be arranged.
  • the resulting compact and low design allows the thread sheet to be divided four times between the wetting after predrying, and also to assign two horizontal heating cylinder pairs one above the other and two vertical heating cylinder pairs next to each other to the diagonal or the deflection rollers arranged there. In this way, a four-fold pre-drying is possible after a single wetting point. If the wetting is then preceded by a division and two wetting points were used accordingly, an eight-fold division would result in the area of the predrying.
  • a division of the thread sheet before wetting and a second division after the squeezing which may be due to the wetting, and accordingly a first pair of heating cylinders in a horizontal plane above each crushing unit and a second pair of heating cylinders in a vertical plane at the outlet of each To store crushing mechanism.
  • the thread groups run in the diagonals mentioned, along which the threads of the heating cylinder arrangement are fed essentially rectified in parallel.
  • the diagonals are at an angle to one another, so that the coulters of thread run towards one another in a correspondingly directed manner.
  • the two alternatives can also be defined by the orientation of the gussets spanned by the heating cylinder pairs: in the first case the gussets open in the same spatial direction, in the other case the gussets are spatially directed away from each other.
  • a group of threads coming from not shown slip trees or the like is divided into two partial thread groups 1 and 2, each with a wetting agent, e.g. Sizing or dye containing trough 3 and 4 lead and to pass on to the trough via a squeezer 5 and 6.
  • a wetting agent e.g. Sizing or dye containing trough 3 and 4 lead and to pass on to the trough via a squeezer 5 and 6.
  • the two sets of threads 1 and 2 are divided again with the help of wet part rods 7 and 8, so that part thread sets 9 and 10 or 11 and 12 are formed.
  • These thread sections 9 to 12 each run approximately along a diagonal 13 and 14 on a pair of heating cylinders 15 and 16 or 17 and 18.
  • the thread groups run towards one another from two sides, so that there are two spatially opposite sequences of immersion trough, squeeze rollers and heating cylinder pairs and that the two diagonals mentioned are not parallel to one another, but rather obliquely, like the legs of an isosceles triangle, are directed towards one another or are opposed to one another.
  • the thread sections 9 to 12 run from the heating cylinder pairs 15 to 18 each via a union roller 19 and 20 to a final dryer, designated overall by 21, which in the exemplary embodiment consists of four heating cylinders 22 to 25.
  • the reunited threads in the final dryer 21 run over a deflecting roller 26 as a completely dried thread sheet 27, e.g. to an undrawn warp beam, further.
  • the distance between the outlet 28 of the squeeze unit 5 or 6 and the run-up point 29 on one of the pairs of heating cylinders 15 to 18 of the pre-dryer can be kept to a certain extent "around the squeezing unit 5, 6" due to the arrangement of the pairs of heating cylinders 15 to 18, but remains the area of the gusset on both sides of the diagonals 13 and 14 is easily accessible for interventions, for example for inserting and checking conventional measuring devices, wet-section bars or smoothing bars.
  • the space between the two pairs of heating cylinders 15 and 16 or 17 and 18 is so well closed that premature drying when the machine is at a standstill is normally not to be expected.
  • the length of the device according to the invention can be kept to a minimum. Furthermore, since only one level of drying cylinders is provided above each crushing unit, the height of the arrangement according to the invention also remains minimal. A major advantage of the invention is therefore that a minimally short wet field and a minimal length and height of the overall arrangement are possible at the same time will.
  • 15 to 18 intermediate dryer cylinder pairs 30 and 31 can be provided above the heating cylinder pairs arranged in the gusset.
  • the reunification of the thread coulters 1 and 2 subsequent to the intermediate dryer cylinders 30 and 31 can already take place on additional final dryer cylinders 32 which are connected upstream of the final dryer 21 in the direction 33 of the thread. In this way, a basic structure having twelve cylinders can be expanded to fourteen to twenty-four drying cylinders without exceeding the overall height and overall length occupied by known devices of this type.
  • the structure essential to the invention is achieved with a horizontal plane 38 and a vertical plane 39 or 40 for the two interacting pairs of heating cylinders 15/16 or 17/18 of the predrying device.
  • the horizontal plane 38 adjoins the vertical planes 39 and 40 in each case an approximately rectangular gusset 41 or 42, within which the respective wetting device with trough 3, 4 and squeezing mechanism 5, 6 is arranged.
  • the heating roller pairs 15 and 17 of the pre-dryer, designated 43 in the horizontal plane 38 on the horizontal cross member 37, are preferably in the described twelve-cylinder arrangement at the same height above the floor 44 as the upper rollers 22, 23 of the final dryer 21.
  • the installation spaces for the intermediate dryer 30 and 31 can be shortened, with a subsequent expansion of the predrying possibly having to be dispensed with.
  • the final dryer can then also be placed directly next to the predrying cylinders 18 and equipped with four or six cylinders. This gives you a compact 12- or 14-cylinder dryer with 4-way warp pitch.
  • Fig. 2 relates to the case of a four-fold division of the thread sheet in the area between the wetting point and the pre-dryer.
  • the final dryer can be designed similar to that in FIG. 1.
  • the groups 61 and 62 then run over the horizontal heating cylinder pairs 57 and 58, and the groups 63 and 64 over the vertical heating cylinder pairs 59 and 60. After predrying, they are on this looping path the thread sections 61 to 64, possibly with the interposition of deflection rollers 65, 66 as in FIG. 1, brought together again on a projecting roller 67 and, if necessary, passed to the final drying - as in FIG. 1.
  • the two diagonals 78, 79 in the gussets 80, 81 are roughly like the legs of an isosceles triangle or like the surfaces of a roof and meet on a line, approximately in the area of the union roller 84. While in the Series connection according to FIG. 1 of the trough 3, 4, the pair of squeeze rollers 5, 6 and the vertical plane 39, 40 in the given sequence in the same direction spatially follow one another in FIG. 3 (and FIG. 4) for the elements 4, 6 , 40 the spatially reverse order as provided for the elements 3, 5, 39. The two vertical planes 39 and 40 are therefore closer together than the crushing units 5 and 6, and especially the troughs 3 and 4.
  • FIG. 4 a similar structure to that in Fig. 3 is provided, however each of the thread sets 1, 2 following the squeezing mechanism 5, 6, in principle, just as in FIG. 1, divided into two thread sets 9, 10 or 11, 12, so that the thread set 9 via the heating cylinder pair 15, the thread set 10 over the heating cylinder pair 16, the partial thread family 11 over the heating cylinder pair 17 and the partial thread family 12 over the heating cylinder pair 18 as well as all partial thread groups following the heating cylinder pairs 15 to 18 to the one unifying roller 84 and from there to the final dryer 21.
  • An essential difference between FIGS. 3 and 4 is thus that each of the thread sections 1 and 2 divided again after the pinch mechanism 5, 6 and the lower thread sets run over a pair of heating cylinders to the unifying roller 84 and from there to the final dryer 21 .
  • the group of threads coming from the first pre-dryer 16, 15 follows the roller 84 (union roller) in the dashed arrow direction 85 onto the cylinder of the second pre-dryer 18, 17 which then rotates in the opposite direction of rotation.
  • the arrangement according to FIG. 3 also possible to work wet-on-wet, i.e. to wet, pre-dry, rewet and pre-dry again.
  • the undivided thread group coming from the first dryer runs through the roller 84 (merging roller) in the direction of arrow 86 under the second pre-dryer and via its trough 4 into the second pre-dryer.
