Definitions

  • the invention relates to a texturing machine with a height adjustable Thread feeder according to the preamble of claim 1, s. the document US-A-3 981 128.
  • Texturing machines with height-adjustable thread feeders are further out following publications known. From DE-PS 23 48 322 a thread feeder is known, which a height-adjustable handrail with slide guide and a rope mechanism described with pulleys for bridging larger operating heights.
  • the mechanism is relatively complicated and requires long operating paths in manual operation of the handrail and also requires in addition to a high level of force, a high level of skill on the part of the operator.
  • DE-PS 1 817 084 is a manually lifting and lowering rod known as a gallows for a thread guide. Again, it is for them Operator required the rod manually with great force and a lot Raise or lower skill.
  • From DE-AS 21 55 514 is also a manually displaceable rod known with guides as thread feeders.
  • the texturing machine which has a height-adjustable Thread feeder for applying a thread in a heating device and / or Cooling device is provided and in which at each workstation Thread over a delivery plant, the heating device, the cooling device, one False twist and a take-off unit is wound up.
  • the threads in the heaters melt quickly can or even burn, it is desirable to remove all threads quickly to remove from the heaters.
  • the operator is as possible easy-to-use thread feeder required.
  • the thread feeder has a sliding element with at least one magnet, which is attached to the outer surface of a sleeve and slidable thereon is attached.
  • the polarity of the magnet is opposite to the polarity one guided inside the sleeve and displaceable pneumatically with compressed air rodless magnetic piston.
  • compressed air Magnetic pistons can use the sliding element with continuous supply of compressed air which the thread guide can be moved into a desired position or can also be held in this by a corresponding circuit.
  • control of the compressed air supply to the respective side of the in the sleeve guided magnetic piston takes place by means of a control valve, which is preferably is designed as a 4/3-way valve.
  • the magnetic piston can be controlled so that the thread feeder is in any desired position Position can be locked.
  • the 4/3-way valve can be manually switched between a first rest position for retracting or driving the Thread guide, a second locking position for holding the thread guide in a certain position and a third locking position for extending the Thread guide can be adjusted.
  • a first rest position for retracting or driving the Thread guide
  • a second locking position for holding the thread guide in a certain position
  • a third locking position for extending the Thread guide can be adjusted.
  • an additional 2/2-way valve is provided, which has a separate control device is controlled.
  • This 2/2-way valve is included an additional compressed air connection connected to the 4/3-way valve, so that in the event of a power failure via this additional compressed air connection, the 4/3-way valve is so controllable that the thread guide is retractable. That is so far important than in the event of a power failure due to their heat capacity, the heaters Maintain temperature for a relatively long time. The one that was no longer extracted Thread can thus come into contact with the heater surfaces and thereby melt or burn, which is why it is important to such a power failure the thread easily, relatively quickly and easily led out of the heater or also from the cooling device can be. This is done by retracting the thread guide.
  • the locking positions realized by means of a plunger.
  • this tappet the 4/3-way valve, d. h. his spool controlled, this spool as Double piston is formed and, depending on the locking position, the supply of compressed air controls to the bottom and / or top of the magnetic piston.
  • the different locking positions of the plunger are close enough and need only the distance between the individual pistons of the double piston correspond so that the corresponding leads to the Bottom or top of the magnetic piston can be covered or released are. This results in short distances that are easy for the operator and can be carried out with little effort.
  • these locking positions are provided in the plunger locking grooves, which engage in spring-loaded locking elements, so that by moving the Plunger engages in the desired locking groove.
  • the direction of operation is in accordance with the desired direction of movement of the Thread guide.
  • the direction of actuation is to be understood as the direction in which the plunger must be pressed or pulled.
  • the locking grooves can both between the plunger handle and the Double piston or between the individual pistons of the double piston be arranged.
  • the latter type represents a more compact type for the 4/3-way valve serving as a control valve.
  • Another embodiment shows an advantageous embodiment of the upper stop, in which a contact switch is integrated.
  • control pulses can be transmitted to a control device for opening and closing a heating flap of the heating device.
  • the operator can thus control both the thread feeder and the heating flap with a single actuation of a control valve. It is particularly advantageous here if the heating flap is adjusted with a control device that is pressurized with compressed air.
  • the thread feeder and the control device can be supplied with a pressure source.
  • Fig. 1 shows a pneumatic circuit diagram of a basic arrangement of a first embodiment of the invention.

This will make the magnet attached to the outer periphery of the sleeve or Gleitelememt 14 when pressure is applied to the magnetic piston inside the sleeve moves up and down.
  • a thread guide 6 is arranged by means of which the thread is inserted into the heating device 8 or cooling device 9 can be.
  • the 4/3-way valve 2 is controlled via a 2/2-way valve 3 which is in turn controlled by a control device 4.
  • the 2/2 way valve 3 serves that in the event of a power failure, the compressed air source 1 with the in the sleeve 26 of the thread feeder 5 formed above the magnetic piston 7 Room is connected, so that in this situation with compressed air supply this space the magnetic piston 7 is moved from top to bottom.
  • Fig. 2 shows the basic structure of a texturing machine, in which the thread 10 from the payout spool 34 at each corresponding work station via a delivery unit 11, which consists of corresponding conveyor rollers, one Heating device 8 supplied. At the end of the heater 8 is a deflection roller 36 over which the thread 10 runs and is deflected, so that he then enters a cooling device 9. From the cooling device the thread 10 becomes a false twister 31 and a take-off mechanism 12 fed from where it is fed to a winder 13. At a In another embodiment, the thread 10 is passed through in front of the delivery mechanism 12 led another heater 33. Between the heater 33 and the False twist 31, the delivery mechanism 32 is arranged.

  • the compressed air connection 21 is with the ventilation channel 30 of the double piston connected so that the top of the Magnetic piston 7 is relieved.
  • the magnetic piston 7 is moved up to the stop 43. Because of the different polarity of the ring magnets of the magnetic piston 7 inside the sleeve 26 and the ring magnet sliding on the outside thereof 28 thus the thread feeder 6 becomes synchronous with the movement of the magnetic piston 7 moves.
  • FIG. 5 shows the thread feeder according to FIG. 3, but in a third latching position of the plunger 16.
  • This third locking position in which the ball 18 with Spring 19 engages in the third locking groove, causes the compressed air connection 22 is connected to the ventilation duct 30, so that the underside of the Magnetic piston 57 is relieved.
