Definitions

  • the invention relates to a texturing machine with a height-adjustable thread feeder according to the preamble of claim 1.
  • Such texturing machines with height-adjustable thread feeders are known.
  • a thread feeder is known, which describes a height-adjustable handrail with sliding guide and a rope mechanism with deflection rollers for bridging larger operating heights.
  • the mechanism is relatively complicated, requires long operating paths in the manual operation of the hand bar and, in addition to requiring a high level of force, requires a high level of skill on the part of the operator.
  • a thread feed rod with straight guides is also known, which can be operated manually and has swivel arms for receiving thread guides.
  • This manually operated thread feed rod also requires a high level of force and skill, especially when the machine is at great heights.
  • the thread feeder has a sliding element with at least one magnet, which is attached to the outer surface of a sleeve and is slidably attached thereto.
  • the polarity of the magnet is opposite to the polarity of a rodless magnetic piston guided inside the sleeve and displaceable pneumatically with compressed air. Due to the compressed air-guided magnetic piston, the sliding element with which the thread guide can be moved into a respective desired position or can also be held in this position by means of a corresponding circuit when the compressed air supply is continued.
  • the compressed air supply to the respective side of the magnetic piston guided in the sleeve is controlled by means of a control valve, which is preferably designed as a 4/3-way valve.
  • the magnetic piston can be controlled so that the thread feeder can be locked in any desired position.
  • the 4/3-way valve can be manually adjusted between a first locking position for retracting or moving the thread guide down, a second locking position for holding the thread guide in a specific position and a third locking position for extending the thread guide. Due to the different locking positions, the supply of compressed air from a compressed air source to the top or bottom or to the top and bottom of the magnetic piston is realized.
  • the magnetic piston in the sleeve is shifted from top to bottom, i.e. the sliding element or the thread guide is retracted.
  • a 2/2-way valve is additionally provided for controlling the 4/3-way valve and is controlled via a separate control device.
  • This 2/2-way valve is connected to an additional compressed air connection on the 4/3-way valve, so that in the event of a power failure the 4/3-way valve can be controlled via this additional compressed air connection so that the thread guide can be retracted.
  • This is important because in the event of a power failure, the heaters maintain their temperature for a relatively long time due to their heat capacity. The thread that is no longer conveyed can thus come into contact with the heater surfaces and thereby melt or burn, which is why it is important that the thread can be removed easily, relatively quickly and easily from the heater or from the cooling device in the event of such a power failure can. This is done by retracting the thread guide.
  • the detent positions are realized by means of a plunger.
  • This tappet controls the 4/3-way valve, ie its control piston, this control piston being designed as a double piston and controlling the supply of compressed air to the underside and / or to the top of the magnetic piston depending on the detent position.
  • the various locking positions of the plunger are close enough to one another and only have to correspond to the distance between the individual pistons of the double piston, so that the corresponding feed lines or leads to Bottom or top of the magnetic piston can be covered or released. This results in short distances that can be carried out easily and with little effort by the operator.
  • locking grooves are provided in the plunger, which engage in spring-loaded locking elements, so that by sliding the plunger, they snap into the desired locking groove.
  • the direction of actuation 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 be arranged both between the tappet handle and the double piston or between the individual pistons of the double piston.
  • the latter design represents a more compact design 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.
  • a compressed air source 1 is connected to the thread feeder 5 via a 4/3-way valve 2.
  • the thread feeder 5 has a sleeve in which a magnetic piston can be moved up and down by means of pressurization without a piston rod.
  • a sliding element 14 is slidably attached as a magnet, which has a polarity which is different from that of the magnetic piston in the interior of the sleeve.
  • the magnet or slide element 14 fastened to the outer circumference of the sleeve is moved up and down when the magnetic piston is pressurized inside the sleeve.
  • a thread guide 6 is arranged, by means of which the thread can be inserted into the heating device 8 or cooling device 9.
  • the 4/3-way valve 2 is controlled via a 2/2-way valve 3, which in turn is controlled by a control device 4.
  • the 2/2-way valve 3 is used so that in the event of a power failure, the compressed air source 1 is connected to the space formed in the sleeve 26 of the thread feeder 5 above the magnetic piston 7, so that in this situation the compressed air source 7 of the magnetic piston 7 from this space is moved up and down.
  • Fig. 2 shows the basic structure of a texturing machine, in which the thread 10 is fed from a supply unit 11, which consists of appropriate conveyor rollers, to a heating device 8 at each corresponding work station of the thread 10. At the end of the heating device 8 there is a deflection roller 36, over which the thread 10 runs and is deflected, so that it then enters a cooling device 9.
  • the thread 10 is fed from the cooling device to a false twister 31 and a take-off unit 12, from where it is fed to a take-up 13.
  • the thread 10 is passed through a further heater 33 in front of the feed mechanism 12.
  • the delivery mechanism 32 is arranged between the heater 33 and the false twister 31.
  • the thread feeder 5 is shown in the upper part of the texturing machine between the heater 8 and the cooling device 9 above the operating aisle 35.
  • the elongated rod is designed as a sleeve 26 which has a connecting plug for compressed air on one side and which on its other side, ie the lower side in FIG. 2, the actual 4/3-way valve which can be actuated by a tappet 16 2 has.
  • the sliding element 14 guided on the outside of the sleeve 26, to which the thread guide 6 is fastened, is shown in the uppermost position in FIG. 2.
  • the top position corresponds to the Position in which the control valve has supplied compressed air from the compressed air source 1 to the underside of the magnetic piston 7 until it is in the sleeve in its uppermost position in contact with the inlet plug or in an external stop.
  • FIG. 3 shows the thread feeder in a first exemplary embodiment of the 4/3-way valve 2.
  • a compressed air source 1 is provided on the control valve, via which compressed air is supplied to the control valve.
  • a feed line is led from this control valve to the underside of a rodless magnetic piston 7 or to the top of this magnetic piston 7, which is guided in a cylindrical sleeve 26.
  • a sliding element 14 with magnets is slidably on the outer circumference of the sleeve 26, to which the actual thread guide 6 with a deflection roller 36 is attached.
  • the magnetic piston 7 has a plurality of ring magnets 29 arranged parallel to one another.
  • the ring magnets 28 are arranged in the sliding element 14 on the outer jacket.
  • a compressed air connection 20 for the connection of the compressed air source 1 to the control valve
  • a compressed air connection 21 for the connection of the control valve 2 to the top of the magnetic piston 7 via a compressed air connection piece 24 on the top of the sleeve 26 for the application the top of the magnetic piston
  • a compressed air connection 22 for acting on the magnetic piston 7 from the bottom
  • a compressed air connection 23 for automatically retracting the thread guide, ie for removing the thread from the heating device 8 or the cooling device 9.
  • the double piston 15 of the control valve 2 also has a tappet 16 with a tappet handle.
  • the first locking position shown in Fig. 3 corresponds to the position in which the compressed air from the compressed air source 1 via the compressed air connection 20 and the compressed air connection 22 acts on the underside of the magnetic piston 7, whereby this is extended, ie is moved from bottom to top.
  • the compressed air connection 21 is connected to the ventilation channel 30 of the double piston, 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 28 sliding on the outside thereof, the thread feeder 6 is thus moved synchronously with the movement of the magnetic piston 7.
  • Fig. 4 corresponds to the basic arrangement according to the invention according to Fig. 3, but in which the plunger 16 is in the second latching position, which corresponds to the holding of the position of the thread guide 6.
  • the pressure connections 20 for the supply of compressed air from the compressed air source 1 the compressed air connection 21 for the application of the top of the magnetic piston 7 and the compressed air connection 22 for the application of the underside of the Magnetic piston 7 arranged between the individual pistons 15 of the double piston.
  • compressed air is guided from the compressed air source both to the upper side of the magnetic piston 7 and to the lower side thereof.
  • the same pressure prevails both on the top and on the bottom of the magnetic piston 7, as a result of which the magnetic piston and thus the thread guide 6 are maintained in the respective position.
  • FIG. 5 shows the thread feeder according to FIG. 3, but in a third latching position of the ram 16.
  • This third latching position in which the ball 18 engages with the spring 19 in the third latching groove, causes the compressed air connection 22 to be connected to the ventilation channel 30 , so that the underside of the magnetic piston 57 is relieved.
  • the two other compressed air connections 20, 21 are thus connected to one another via the space located between the individual pistons 15 of the double piston, so that compressed air from the compressed air source 1 reaches the top of the magnetic piston 7 directly via the connecting piece 24, whereby this together with the thread guide 6 is moved from top to bottom.
  • control valve 2 is connected to a further compressed air connection 23, which ends in a chamber on the end face of the double piston. If this compressed air connection 23 is pressurized with compressed air, preferably from the compressed air source 1, the double piston is shifted into the third latching position shown in FIG. a switch position for retracting the thread layer.
  • a simple laser system with a sensor can be used to check whether all thread feeders are in the respective operating position.
  • a laser is arranged transversely to the thread feeder 5, so that the laser beam can detect the position of the respective thread feeder 5. This can be done on the one hand by monitoring the actual position of the thread guides 6, but this can also be achieved by detecting the position of the ram 16.
  • FIG. 6 shows a further exemplary embodiment, which corresponds in principle to that according to FIG. 3.
  • the control valve 2 has the locking grooves for fixing the corresponding locking positions in the area between the two pistons 15 of the double piston.
  • a locking pin 26, which engages in the corresponding locking groove 17 depending on the locking position, serves as locking elements.
  • the sleeve 26 of the thread feeder 5 is preferably made of metal; in a still preferred embodiment, the sleeve 26 consists of a stainless steel tube. However, it is also possible to form the sleeve 26 from a plastic tube. In any case, the tube is inserted in an aluminum profile.
  • the compressed air lines are preferably cast into the profile itself. At one end, the control valve with the plunger 16 or the shift rod is arranged. At the opposite end is the compressed air nozzle 24, via which a pressure connection to the pressure source 1 is realized.
  • the aluminum profile is preferably designed as an extruded profile.
  • Fig. 7 shows a further embodiment in which the thread feeder rests with its sliding elements 14 on an upper stop.
  • the stop is formed by a contact switch 38.
  • the contact switch 38 is connected to a control device 37.
  • the control device 37 consists of a control valve 39 and a lock cylinder 40.
  • the control valve 39 is moved into its left switching position by means of the contact switch 38.
