Definitions

  • the invention is based on an air texturing machine for processing several monofilaments, with an air texturing unit and a worktop on which elements such as delivery mechanisms, heating pins and the like are arranged.
  • Air texturing machines are used to consistently crimp smooth, structureless synthetic filament yarns using their thermoplasticity.
  • Several original yarns can be processed into a textured yarn with fancy yarns of different lore.
  • the yarns are fed to an air texturing nozzle via delivery units.
  • the delivery plants are usually operated at different speeds, which can be selected due to different, interchangeable toothed belt wheels.
  • heating pins are also sometimes provided, so that the yarns are next to one Cold stretching can also be hot stretched as required before the actual texturing.
  • the yarn can be stretched, fixed, shrunk and finished before it is wound up.
  • the process steps mentioned are carried out by machines which are known to have a plurality of housings for the supplying plants or by so-called "plate machines" in which the supplying works, heating pins and the like are attached to a front plate.
  • the known air texturing machine is a so-called "plate machine", in which the working level for the operating personnel is a front surface from which the delivery mechanisms, heating pins and the like protrude and point to the operating personnel with their end faces.
  • the supply units required, like the heating pins, are arranged individually on the plate. This has the disadvantage that if several yarns are to be textured into one yarn, the structural units become large. This makes it difficult to operate such an air texturing machine.
  • the invention is therefore based on the object of developing an air texturing machine of the type mentioned in such a way that it is easier to handle and operate with a clear structure.
  • the air texturing machine according to the invention thus has the significant advantage that, due to its structure, the delivery mechanisms and the heating pins and the other elements on the worktop are not only clearly visible to the operating personnel at all times, but the arrangement of the worktop described also allows air texturing machines with their rear walls to adjoin one another can be set up. A space-saving, element-like construction of several air texturing machines according to the invention is possible, and important units can be shared by the respective air texturing machines as required. If the air-texturing machines according to the invention are set up with their rear walls in relation to one another and further ones are placed directly adjacent to one another, clear operation, maintenance and monitoring of the individual air-texturing machines is still possible.
  • the elements on the worktop remain easily accessible and the toothed belt and toothed belt wheels can also be replaced from the operating side of the machine. If one of the air texturing machines according to the invention is to be converted, serviced or switched off to change the bobbin, then it can the immediately adjacent air texturing machines will continue to be operated. In the production of a wide variety of textured yarns, this allows a high degree of flexibility in the operation of the object according to the invention and ensures good machine utilization.
  • At least two air texturing machines according to the invention are set up, not only is it possible to line up the machines directly, but the machines can also be arranged in such a way that a front and rear processing position is created without disadvantage.
  • the delivery mechanisms have at least two rollers which can be operated at different speeds and which are arranged coaxially.
  • the clarity of the thread run is improved and individual positions can be more easily surveyed.
  • the worktop can basically be designed more clearly and depending on the application and application, the worktop can easily accommodate additional elements such as further supplying units, heating pins and brackets without adjacent elements would be impaired in their function and it would disturb the clear arrangement of the elements on the worktop.
  • a traversing device means for winding the textured yarn and a drive are preferably provided on the worktop.
  • the traversing device with the overflow rollers and with the running laying rollers can also be operated with one drive for several air texturing machines.
  • the air texturing machine according to the invention preferably borders with the outside of the rear wall of a machine frame to the outside of the rear wall of a second machine frame.
  • toothed belt wheels are arranged on the back of the worktop, which interact with the elements via axes and preferably with one another via toothed belts, the transmission ratio of the individual delivery mechanisms to one another can be checked by the operating personnel in a simple manner.
  • both the arrangement of the toothed belt wheels and the arrangement of the delivery plants can be viewed.
  • the machine frame has two vertically extending side supports open to the front.
  • the machine frame is not only stable and torsionally rigid due to the side supports, but the side supports can also be used as a yarn channel.
  • the yarns coming overhead from a creel are protected and always visible to the individual supply plants in a clear manner in the yarn channel.
  • three delivery mechanisms each with two rollers and a traversing device and one heating pin each, are arranged below an air texturing nozzle and at least one additional delivery mechanism is provided above the air texture nozzle, which supplies the textured yarn to a convection heater and / or the means for winding.
  • the arrangement has the advantage that the air texturing machine according to the invention can also be made compact in height.
  • the yarns from the creel to the air texturing machine can always be guided at a height that allows the yarns to be threaded in by hand and without climbing aid. This is also possible if a large number of delivery plants are necessary for processing the yarns, since a delivery plant according to the invention can replace two delivery plants known from the prior art.
  • the delivery mechanism has three separately operable, coaxially arranged rollers.
  • the delivery unit is arranged at a distance from a heating element.
  • an air texturing unit and an operating, switching and monitoring panel are installed between the side supports.
  • the individual yarns are processed and guided underneath the air texturing unit and the operating, switching and monitoring panel and the textured yarn runs above the air texturing unit and the operating, switching and monitoring panel. This measure contributes to an overall clearer machine structure.
  • the machine frame has a working channel in which a water pipe, an air pipe, a suction pipe and a finishing supply are preferably guided.
  • the air texturing nozzle is displaceably arranged in a housing.
  • the air texturing machine according to the invention thus meets all the extended requirements that are placed on a machine in the processing of yarns into an air textured or air-entangled yarn.
  • the air texturing machine according to the invention several can be lined up laterally Build up working levels and working levels diametrically.
