Definitions

  • the invention relates to a false twist unit according to the preamble of claim 1.
  • Such a false twist unit is known.
  • DE 41 10 464 A1 describes a friction false twist unit which is operated by an externally attached motor via a toothed belt.
  • the actual false twist unit is arranged on a support or a pivotable base plate which can be moved by an adjusting lever in the direction of the motor rigidly attached to a spindle bench, so that the actual friction false twist unit is movable relative to the drive motor by providing an additional mechanism.
  • This additional mechanism enables the toothed belt to be released, which makes it possible to lift the friction false twist unit out of the machine.
  • a friction false twister in which the friction unit is arranged on a support plate.
  • the friction unit can be plugged onto the support plate.
  • the drive of the friction unit which has shafts provided with friction disks, takes place here by means of a centrally arranged belt drive, into which the unit can optionally be pivoted.
  • the false twist unit of which likewise consists of friction disks rotating in the same direction, the axes of which are arranged parallel to one another around the thread path.
  • the friction disks of the false twist unit are each designed as part of the rotor of an electric motor, so that the drive belt present in the listed prior art friction twist units for driving all three shafts equipped with the friction disks by an electric motor is omitted, but a separate one for each individual shaft Electric motor is required.
  • the main disadvantage of such an arrangement is that the arrangement of a separate electric motor for a shaft equipped with friction disks entails, among other things, higher demands on the control of all three electric motors. In order to be able to carry out certain repairs, the entire unit together with the respective drive must be removed from a housing containing the electric motors for the friction disc shafts in such a friction false twist unit.
  • the actual false twist assembly which essentially consists of friction disks arranged in the same direction rotating on shafts, and the drive motor are arranged in separate units on a base plate or on a base frame.
  • the axes of the friction disc shafts are arranged parallel to each other around the thread path.
  • a motor drive pulley is provided on the driven side of the drive motor, and at least one of the friction pulley shafts has a pulley. Motor drive pulley and pulley can be connected to each other via a drive belt.
  • the shafts on which the friction disks are arranged are mounted in a bearing block.
  • the bearing block is detachably attached to the base frame by means of a guide.
  • the guide is arranged axially parallel to the shafts and at a constant distance from the axis of the drive motor on the base frame.
  • the guide as such is formed by a pin fastened in the base frame and a bore made in the bearing block.
  • the pulley In order to make it easier to put on the actual false twist unit and thus to insert the pulley into the running plane of the drive belt, the pulley preferably has a cone at its free end, the diameter of which is different from that of the pulley rejuvenated. This cone causes the drive belt to slip over the cone in the direction of the belt pulley when the false twist unit is placed on it and automatically pulls onto the belt pulley when it starts up again.
  • the drive belt is arranged according to the invention in a drawer housing which can be moved in the running plane of the drive belt.
  • An advantage of such a drawer housing is that it is no longer necessary to swing the false twist unit out of its normal position after lifting with or over the base plate, but that after lifting the actual false twist unit, the drawer housing can only be moved in the direction of the running plane of the drive belt , and thereby the drive belt tension is reduced in such a way that removal or replacement of the drive belt is easily possible without great assembly effort.
  • the drawer housing has a bevel and a shoulder in a region of the motor drive disk.
  • the drive belt slides up the bevel and under the engine drive pulley into the shoulder. This prevents the drive belt from falling down again.
  • the housing drawer By subsequently moving the housing drawer in the opposite direction, i.e. in the direction of the false twist unit, the drive belt lying in or on the shoulder is moved towards the motor drive pulley.
  • the drawer housing has guides for the drive belt on its upper side and / or on its lower side to fix it on. After the drive belt has moved towards the motor drive pulley in the opposite direction of the housing drawer as a result of the movement described above, the side frets of the motor drive pulley lie essentially flush against the upper and lower limits of the shoulder. As a result, the drive belt is pulled onto the circumference of the motor drive pulley when it is tensioned, ie when the cone of the pulley is threaded on the side opposite the motor drive pulley.
  • the drive belt is preferably a toothed belt which engages in a correspondingly adapted toothing of the motor drive pulley and the belt pulley.
  • the toothing preferably extends to the cone.
  • the drawer housing can preferably be of modular design, so that corresponding drawer housing modules can be used for different sizes of such a false twist unit.
  • a spring is provided, which forms the drawer housing on the base plate or the base plate Housing frame supports.
  • the pulley is preferably seated on one of the three shafts provided with friction disks, the three shafts running in the same direction at the same speed being ensured by a further circulating belt which ensures a connection of the drive of the three shafts to one another.
  • a magnetic coupling between the pulley and the drive belt coupling, preferably a magnetic coupling, which has two magnetized bodies opposite one another on the end face with a gap, with alternating magnetic polarity in the circumferential direction.
  • a magnetic coupling i.e. a separation of the drive path between the drive motor output and driven friction disk shaft, a displacement of the drawer housing to loosen the drive belt and thus to the possibility of replacing it.
  • the complete false twist assembly shown in FIG. 1 has a drive motor 1 with connecting lines 19, next to which the actual false twist assembly is arranged on a base plate 14 designed as a frame structure.
  • This actual false twist unit has three shafts 2, which are arranged in the corner points of an equilateral triangle and are rotatably mounted in a shaft bearing block 15.
  • the waves 2 carry a plurality of friction disks 3 which overlap one another, with their axes being arranged parallel to one another around the thread path.
  • a motor drive pulley 4 is arranged on the output shaft of the drive motor 1.
  • One of the three shafts 2 of the actual friction swirl unit carries a pulley 5 in the same plane with the motor drive pulley on the end projecting into the base plate 14.
  • This pulley 5 is driven by a drive belt 6 by means of the motor drive pulley driven by the motor 1.
  • each of the shafts 2 has a pulley 16, all three pulleys 16 lying in the same plane and the shafts 2 and thus the friction disks 3 by a circulating belt 17 wrapping around the pulleys 16 in a triangle in the same direction and the same speed are offset.
  • two guide pins 18 are provided in the shaft bearing block 15 of the actual friction swirl assembly, in which a position of the actual friction swirl assembly with respect to the drive motor is guaranteed, which ensures optimum drive belt tension when the motor drive pulley 4 and the pulley 5 rotate.
  • the guide pins 18 also ensure that the actual false twist unit is not pivotable with respect to the base plate, but can only be removed from the base plate in the axial direction.
  • a drawer housing 7 is arranged, which is supported on the base plate 14 via a spring 13 such that the housing drawer 7 can be displaced in the direction of the running plane of the drive belt 6 against the action of the force exerted by the spring 13.
  • This housing drawer 7 is used to thread the pulley 5 of the actual false twist assembly into the drive belt 6, which is realized by axially threading the pulley 5.
  • the Pulley 5 is provided with the cone 8 at its free end.
  • the housing drawer 7 has guides 11 and 12 on its upper side and on its lower side. On the one hand, these guides 11, 12 serve to prevent the drive belt 6 from evading. On the other hand, the upper guide 11 serves to remove the drive belt 6 from the pulley 5 of the driven shaft 2 and thus to loosen it when removing the actual false twist unit, which is guided axially by the guide pins 18. After pulling out the actual false twist unit, the drive belt 6 remains essentially in its running plane, which is brought about by the guides 11, 12.
  • the housing drawer 7 After removing the actual false twist unit, the housing drawer 7 can be moved against the action of the force of the spring 13 in the direction of the drive belt running plane towards the drive motor 1, whereby the drive belt tension is loosened and the drive belt 6 detaches from the motor drive pulley 4 from its toothing.
  • the drive belt 6 can thus be easily removed from the housing drawer 7 and possibly replaced by a new one.
  • the drive belt 6 When the actual false twist unit is replaced, it is sufficient if the drive belt 6 contacts the cone 8. The drive belt 6 then runs automatically on the largest diameter, which is formed by the pulley 5. The toothing extends to the cone 8. Before the actual false twist unit is used, it is necessary to move the housing drawer 7 in the direction of the motor drive disc 4 against the action of the force of the spring 13. As a result, the drive belt 6 receives a radial gap between the housing drawer 7 and the motor drive pulley 4. To put it back on, the housing drawer 7 has a bevel 9 and a shoulder 10 in the area of the motor drive pulley 4. When the drive belt 6 is pushed into the housing drawer 7, the drive belt 6 slides or slides upwards on the bevel 9 and under the engine drive pulley 4 into the shoulder 10.
  • the drive belt 6 lying in the shoulder or held there is moved toward the motor drive pulley 4.
  • the side frets of the motor drive pulley 4 lie essentially flush against the upper and lower limits of the shoulder 10.
  • the drive belt 6 is under tension, i.e. when the pulley 5 provided with a cone 8 is threaded into the drive belt running plane on the side opposite the motor drive pulley 4, pulled onto the circumference of the motor drive pulley 4 and thus into the toothing.
  • a major advantage of a false twist unit provided with such a housing drawer 7 is that it is easier to replace the drive belt 6, which is often necessary in today's machines due to wear.
  • the guides 11, 12 ensure that the drive belt 6 cannot move substantially out of the running plane during operation and that it is thus ensured that it always runs on the motor drive pulley 4 and the pulley 5.
  • FIG. 2 shows a plan view in a sectional view of the plane AA according to FIG. 1.
  • the housing drawer 7 is shown, which receives the drive belt 6 with the corresponding guides. It is further shown that the housing drawer 7 is arranged in the base plate 14 against the action of the force of the spring 13 in the running plane of the drive belt 6 to be longitudinally displaceable. The chamfer 9 and the paragraph 10 are also visible.
  • the upper guide 11 of the housing drawer 7 is cut away, whereas it can be seen that an opening is provided on the side of the housing drawer 7 opposite the motor drive disk 4, through which opening the can be threaded with a cone 8 pulley 5.
  • the actual false twist unit When threading, the actual false twist unit is guided on a straight guide in the axial direction, ie in the threading direction.
  • this lateral opening in the housing drawer 7 can also be omitted.
  • Sufficient space in the axial direction of the cone 8 on the pulley 5 is sufficient; an opening in the housing drawer 7 is advantageous only for reasons of space.
  • FIG. 3 shows a plan view of the complete false twist unit.
  • the drive motor 1 is flanged with an attachment flange 20 on one side of the base plate 14.
  • the actual false twist unit is secured in the axial direction by the two guide pins 18 and can be guided out of the base plate 14 in the direction of the guide pins 18 when components need to be repaired, assembled or replaced.
  • Corresponding friction disks 3 are shown on the shafts 2, which overlap one another. For the sake of simplicity, the invisible edges of the friction disks 3 resulting from the overlap are not shown in dashed lines.
  • the shafts 2 arranged parallel to each other are arranged in an equilateral triangle around the thread. In Fig. 3, the outlines of the upper outer contour of the housing drawer 7 and the lower guide 12 are also shown in dashed lines.
  • the complete false twist assembly shown in FIG. 4 has a drive motor 1 with connecting lines 19, next to which the actual false twist assembly is arranged on a base frame 14.
  • This actual false twist unit has three shafts 2, which are arranged in the corner points of an equilateral triangle and are rotatably mounted in a shaft bearing block 15.
  • Each shaft 2 carries a plurality of friction disks 3 which overlap one another, their axes parallel to one another the thread are arranged around.
  • a motor drive pulley 4 is arranged on the output shaft of the drive motor 1.
  • One of the shafts 2 of the actual friction swirl unit carries a belt pulley 5 in the same plane as the motor drive pulley 4 on the end 25 protruding into the base plate 27.
  • the belt pulley 5 is driven by a drive belt 6 by means of the motor drive pulley 4 driven by the motor 1.
  • the end 25 of the shaft 2 protruding into the base plate 27 is supported by means of a bearing 26.
  • each of the shafts 2 has a pulley 16.
  • the belt wheels 16 lie in the same plane.
  • the shafts 2 are rotated in the same direction and at the same speed by means of a circulating belt 17 which drives the belt wheels 16.
  • a guide 18 is provided which comprises a pin 18 fastened in the base frame 14 and a bore made in the bearing block 15.
  • the shaft 2 is divided between the pulley 5 of the driven shaft 2 and the pulley 16 and a clutch 24 is arranged at this point.
  • FIG. 5 shows a further preferred exemplary embodiment, in which a magnetic coupling is arranged between the pulley 5 of the driven of the three shafts 2 and the circulating belts rotating in a triangular shape for driving the shafts 2 of the friction disks 3 in the same direction.
  • the driven shaft of the actual friction swirl unit is divided, the two coupling magnetized disks 21, 22, which form the magnetic coupling and are axially opposite at the end with a gap, with the magnetic polarity changing in the circumferential direction, represent the actual coupling.
  • the distance between the two magnetized disks is preferably 1 to 3 mm.
  • This separation has the advantage that a replacement of the drive belt 6 is also possible without pulling out the actual false twist unit from the base plate 14, in which the housing drawer can be moved at any time against the action of the force of the spring 13, so that the tension of the drive belt 6 can be reduced to such an extent that loosening from the motor drive pulley 4 and the pulley 5 is possible.
  • the cone 8 on the pulley 5 is not absolutely necessary.
  • the magnitude of the torque which can be transmitted through the two magnetized disks 21, 22 which are axially opposite one another in the gap 23 depends on the number of magnets arranged in the circumferential direction with alternating magnetic polarity.
  • the magnetic coupling it is also possible for the magnetic coupling to have two disks lying in the same plane with a gap with magnetic polarity changing in the circumferential direction.
  • the thus radially opposing disks of the magnetic clutch are limited to low transmitted torques. Its gap is preferably 1-2 mm.
  • FIG. 6 shows a further exemplary embodiment of a magnetic coupling 24.
  • the magnetic coupling 24 has a first essentially tubular body 22, into which a cylindrical body 21 projects.
