Definitions

  • the invention relates to a device for melt spinning synthetic high polymers according to the preamble of patent claim 1.
  • each spinning beam is equipped with a more or less large number of nozzle packages. Since the nozzle plates and the filters of the nozzle packages only have a runtime of a few days or a few weeks, changing the nozzle package is part of the daily routine. The spinning process should be disrupted as little as possible with the other nozzle packages by changing a nozzle package.
  • the nozzle package to be removed is at a temperature of approx. 250 ° C, and the new nozzle package to be used is preheated to operating temperature so that it is ready for use quickly and does not cause local cooling of the spinning beam.
  • the relatively large weight of the nozzle packs and the unfavorable spatial conditions also contribute to the fact that the nozzle pack change cannot be carried out easily and safely.
  • Various auxiliary devices have therefore already been used to make this process easier and safer.
  • the invention is based on the device described in DE-PS 2 611 940, in which a vertically movable, hydraulically operated pulling rod is arranged above each nozzle packet, the tie rods of which have hooks for hanging the nozzle packet.
  • the invention has for its object to provide a simple device of the type specified in the preamble of claim 1, with which the replacement of the nozzle packs is easier and safer.
  • auxiliary device only one auxiliary device is required for each spinning beam.
  • the end of the arm provided with the supporting element protrudes into the blow duct.
  • the rest of the auxiliary device is at a sufficient distance from the spinning beam, so that the work is not hindered.
  • the removed nozzle package is simultaneously lowered and moved out of the blow chute and held vertically in any position.
  • the feature of claim 4 enables precise positioning in a simple manner.
  • the support member is interchangeable, so that the appropriate support member can be used in different nozzle packages.
  • the nozzle package is secured on the support member against slipping sideways.
  • the feature of claim 8 secures the nozzle package against lifting and makes it possible to tear sticky nozzle packages when lowering the arm.
  • the feature of claim 10 also contributes to security, in that it only allows the fastening screws of the nozzle package to be loosened when the support member is properly locked to the nozzle package.
  • the lock between the support member and the nozzle assembly can be locked so that unintentional loosening is prevented.
  • claim 13 specifies an advantageous embodiment.
  • a spinning beam 3 surrounded by an insulation jacket 2 is suspended from a support structure 1.
  • the spinning beam 3 On its underside, the spinning beam 3 is equipped with a plurality of nozzle packs 4 arranged in a row, which are fastened with screws 5 screwed in from below into chambers 6 of the spinning beam 3 which are open at the bottom.
  • Spinning pumps 7 are arranged on one side of the spinning beam 3, and a melt feed line 8 is connected on the opposite side. Melt-carrying lines 9 can be seen in the interior of the spinning beam.
  • a blow shaft 10 is located under the spinning beam 3. The mouth of a suction channel 11 can be seen in FIG. 1 laterally below the nozzle package 4. Beside the spinning beams 3 hang on the support structure 1 drives 12 for the spinning pumps 7.
  • rails 13 are arranged approximately at the height of the nozzle packs, which are suspended by means of rods 14 on the support structure 1.
  • the rails 13 extend over the entire length of the spinning beam 3 and are expediently extended at least in one place beyond.
  • the rails are U-shaped in cross section, with the open sides facing each other.
  • a carriage 15 is movable, consisting of a chassis 16 with wheels 17 and a box 18 hanging down, to which an arm 19 is attached.
  • the arm 19 is designed as a joint parallelogram.
  • Two rockers 20, 21 are articulated on the box 18 in such a way that the hinge axes 22, 23 lie vertically one above the other.
  • the upper rocker 20 is extended beyond the axis 22.
  • the arm 19 can be pivoted between a horizontal position directed towards the spinning beam 3 and a position pointing downward at an acute angle.
  • the horizontal position - hereinafter referred to briefly as the "working position” - is shown in FIG. 2 with solid lines, the obliquely downward position - hereinafter briefly referred to as the "basic position" - by broken lines.
  • a lateral protective cover 26 is attached, which extends to the upper rocker 20 in the working position and even covers it in the basic position.
  • a coupling 27 which is relatively short in comparison to the rockers and corresponds to the distance between the articulated axes 22, 23 is articulated.
  • two horizontal bushings 28 are attached below, of which only the front one can be seen in the drawing.
  • Rods 29 are slidably guided in the bushes 28 so that they can be moved back and forth in the horizontal direction.
  • a handle 30 and a holding plate 31 are connected to the rods 29.
  • the angled end of a rod 32 is attached to the holding plate 31.
  • a support member 33 for the nozzle packs 4 sits on the other leg of the rod 32, which is directed vertically upward.
  • An essentially square, horizontal table 34 belongs to the support member 33. This is screwed on its underside to a substantially smaller rectangular plate 35. which is flange-welded to the end of a pipe section 36. This is on the rod 32 and is locked on it with a catch 37, which engages in an undetectable recess in the rod 32.
  • Screws 38 are screwed in near two diagonally opposite corners of the table 34, the heads of which form elevations 39 on the upper side of the table.
  • the arrangement of the screws 38 and the dimensions of the screw heads correspond to recesses 40 on the underside of the nozzle package 4.
  • the recesses 40 are created in that the screws 41, with which the nozzle package 4 is screwed together, do not completely fill the associated threaded holes down to the bottom.
  • a plate 42 is fastened under the table 34 with spacing screws 43 which are inserted through elongated holes 44 in the plate 42.
  • the plate 42 has a rectangular recess 45 approximately in the middle, the length of which is somewhat greater than the length of the rectangular plate 35 and the long sides of which slide against the long sides of the rectangular plate 35.
  • the rectangular plate 35 therefore serves as a guide for the plate 42 which can be moved back and forth in the direction of the elongated holes 44.
  • the position of the plate 42 illustrated in FIGS. 3-6 is referred to below as the “ready position”; the other position, not shown in the drawing, in which the plate 42 is shifted to the right, is referred to as the “locking position”.
  • the plate 42 With a catch 46, which is fastened to the underside of the plate 42 and optionally engages through an opening of the plate 42 into a bore 47 or into a bore 48 of the table 34, the plate 42 is in both the ready position and in the locking position lockable.
  • the nozzle pack 4 has recesses 51 on the underside at the corresponding points, which are undercut behind a projection 52.
  • Both the table 34 and the plate 42 are provided with four holes 53 and 54 near the corners.
  • the bores 53 of the table 34 correspond to the bores 55 in which the screws 5 sit, with which the nozzle packet 4 is fastened to the spinning beam 3.
  • the bores 53 of the table 34 and the bores 54 of the plate 42 are offset from one another in the ready position, as can be seen in FIGS. 3 and 5. However, they are in the locked position.
  • the carriage 15 is expediently located on that part of the rails 13 which extends beyond the end of the spinning beam 3, so that it does not interfere with the operation of the blowing shafts. If a nozzle package 4 has to be replaced, it is first moved on the rails 13 to the point where it faces this nozzle package. Then the arm 19 is pivoted from the basic position into the working position. The free end of the arm 19 now protrudes into the blow shaft 10, and the table 34 is located under the nozzle package 4.
  • the handle 30 is used for precise positioning, so that the elevations 39 formed by screw heads snap into the recesses 40.
  • the hook bolts 49 are also inserted into the recesses 51 at the same time. Then, after releasing the catch 46, the plate 42 is brought into the locking position.
  • the hook bolts 49 engage behind the projections 52, and at the same time the holes gene 54 brought to coincide with the holes 53.
  • the catch 42 snaps into the bore 48.
  • the screws 5 can now be loosened with the aid of a socket wrench inserted through the bores 53, 54. Subsequently, the arm 19 with the removed nozzle packet 4 is pivoted back into the basic position.
  • the blow duct 10 When the nozzle pack 4 is removed, the blow duct 10 remains freely accessible under the support member 33.
  • the devices described in connection with FIGS. 3 to 6 ensure that the nozzle package 4 can only be released when it lies properly on the table 34 and is secured against lateral slipping and intentional lifting.
  • the hook bolts 49 make it possible, after loosening the screws 5, to tear off a possibly still stuck nozzle pack.
  • the U-shaped cross section of the rails 13 prevents the carriage 15 from tipping over.
