Definitions

  • the invention relates to a device for melt spinning synthetic filaments according to the preamble of claim 1.
  • a generic device is from the WO 2005/123994 A1 known.
  • the known device consists of a spinning beam, which holds a plurality of spinneret packages in a row-like arrangement on its underside.
  • the spinneret forms a heating chamber which encloses the receptacles of the spinneret packs inside the spinneret.
  • a spinning pump is mounted, which is attached to a pump connection block at the top of the spinner.
  • the spinning pump is associated with a heating means which surrounds the spinning pump with a heating medium in the form of a heating jacket.
  • the spinning pump is in this case formed by a multiple pump and connected by a plurality of melt lines with the spinnerets.
  • the pump port blocks are preferably bolted to the spinner. Frequent heating up and heating down of the spinner bar places a heavy burden on such mechanical connections, so that a regular check as well as a tightening of the screws when using a screw is necessary in order to prevent possible leaks. For this complex disassembly work is required. Furthermore, in the production of synthetic yarns, it is common for a plurality of spinneret packages and spinning pumps to be held on a spinneret. In this case, it is disadvantageous that each of the spinning pumps attached to the spinning beam is assigned a separate heating means in order to obtain a temperature control of the melt-carrying parts. In this case, temperature differences can hardly be avoided. It is an object of the invention to provide a device for melt spinning synthetic filaments of the generic type, in which the spinning pump and the spinneret are held in a low-maintenance and easy to use arrangement.
  • Another object of the invention is to provide an apparatus for melt-spinning synthetic filaments of the generic type, with which a uniform and tailored to the function of the assemblies temperature control of the spinning nozzle packages and spinning pumps is possible.
  • the invention is based on the previous concept of retaining the melt and the components required for the extrusion of the melt on a common support.
  • the separation according to the invention between a spinning beam and a separate pump carrier has the particular advantage that a temperature control adapted to the function of the respective module can be carried out without mutual interference occurring.
  • Another advantage of the invention lies in particular in the flexible arrangement of the spinning pumps within the pump carrier, so that the drive vertically or horizontally aligned or if necessary in an inclined position executable.
  • the arrangement of the pump carrier next to the spinning beam is not limited to a specific position of the pump carrier relative to the spinning beam. Thus, the pump carrier could be arranged both horizontally and vertically next to the spinning beam.
  • the development of the invention is particularly advantageous in which the pump carrier is arranged parallel to a longitudinal side of the spinning beam such that the spinning pump and the spinneret held in a common spinning plane transverse to the spinning beam are.
  • the pump carrier can basically be arranged above or laterally next to the spinning beam.
  • heat transfer media are preferably used, which flow around in a heating chamber, each to be tempered melt-carrying components and assemblies. For this purpose, separate heating chambers are formed in the spinning beam and the pump carrier.
  • the heating of the melt line arranged between the spinning pump and the spinning nozzle package is preferably made possible by a pipe socket which is arranged between the heating chambers of the spinning beam and the pump carrier and which surrounds the melt line in the manner of a jacket at a distance.
  • the separation of the heating chamber can be realized preferably by a trained in the pipe socket blocking means which seals the annular space in the pipe socket concentrically to the melt line.
  • blocking means can be realized in the pipe socket integrated jacket seals or connectors.
  • a temperature-controlled heat transfer medium can be carried out by a common heat transfer medium or by a plurality of separate heat transfer sources, depending on the requirements of the desired temperature of the spinneret and the spin pump.
  • the heat carrier source is formed by an evaporator, which is connected by a steam connection and a condensate connection with at least one of the heating chambers.
  • the threads In the manufacture of synthetic threads, it is also common for the threads to be formed of multiple polymer components.
  • the polymer components are preferably combined within a spinneret stacked thereon to extrude the individual filament strands from a plurality of components.
  • two or more spinning pumps are assigned to the spinneret pack.
  • the spin bars are associated with a plurality of pump carrier, each holding one of several spinning pumps, the spinning pumps are connected by a plurality of melt lines to the spinneret.
  • the individual melt components can be tempered individually during the feed. Only shortly before the extrusion, the melt components in the spinning beam are heated together.
  • the plurality of spinneret packages are preferably held in a row-like arrangement in the spinning beam, wherein the spinneret packages associated spinning pumps are also arranged in a row-shaped arrangement in the pump carrier.
  • all spinning pumps can be jointly tempered by the fact that the pump support has a plurality of pump connection blocks for connecting the spinning pumps and the melt line within the heating chamber, each pump connection block a cylindrical plug-in housing is associated for receiving one of the spinning pumps.
  • the heating chamber is used to jointly temper a plurality of spinning pumps and the connections and melt lines.
  • the plug-in housing is preferably integrated on the pump carrier such that an open end of the plug-in housing protrudes from the heating chamber.
  • the pump carrier is particularly advantageous for the assembly and disassembly of the spinning pumps.
  • the spin pumps can be advantageously mounted from the outside to the pump carrier.
  • de pump carrier is formed by a tube to which the plug-in housing and a plurality of pipe sockets are attached.
  • the attachment can be realized by welded joints.
  • the advantageous development of the invention in which the spinning beam has a nozzle receiving opening at an upper side and a spinning opening at a lower side, in which the spinneret pack can be inserted, is particularly advantageous for mounting the spinneret pack from an upper side of the spinneret.
  • This allows the replacement of the spinneret packages run in a user-friendly manner.
  • An assembly and disassembly of the spinnerets packages takes place exclusively from the top of the spinneret, so that the usually arranged on the underside of the spinneret package cooling device for cooling the extruded filaments can connect in a compact design directly to the spinning beam.
