Definitions

  • the present invention relates to a drive device for traversing machines of textile machines, in particular of spinning machines, which is equipped with at least one driven by a drive drive means for providing the drive energy required for the operation of the traversing devices.
  • the present invention relates to a method for driving traversing machines for textile machines, in particular for spinning machines, by means of which a yarn to be wound is changed, and in which the drive energy required for this purpose is provided by a driven drive means.
  • Image disturbances arise, for example, when the oscillating motion and the rotational speed of the coil to be built up in such a ratio are that form interference. This can then lead to a thread being wound on a subsequent traverse stroke, exactly above the thread position of the previously performed traverse stroke. In this case, unwanted thick spots are formed at certain points of the coil and destroy the desired uniform coil structure.
  • the edge structure of a coil depends essentially on the quality of the traversing movement transmitted by the traversing device to the yarn. If, for example, the traverse inversion occurs too fast in the edge region, too little yarn is wound up at this point and falling edges occur. If, in the opposite direction, the yarn to be wound does not stay too long in this area due to a too slow reversing movement, the edge structure is excessively strong.
  • the object of the invention is therefore to provide a traversing device and a method by means of which comparable traversing results can be achieved and which is simpler and less expensive.
  • a drive device for traversing devices of the type mentioned which is characterized in that the at least one drive means is connected via a motion converter with the traversing device, which converts an undirectional movement of the drive means in an at least bidirectional movement and this on the traversing device transmits, wherein at least two traversing devices are connected to a drive means.
  • the power transmission takes place by means of friction or shape flow.
  • numerous well-proven methods and designs are known in the art. From these, depending on the existing circumstances and requirements, the most favorable can be selected. moreover The known methods and constructions offer a high degree of reliability.
  • the drive means is a drive belt.
  • a drive means may be formed for example as a flat belt or as a toothed belt.
  • Belt drives are technically very manageable and available with high reliability.
  • it is also possible with modern belt drives easily to transfer the drive energy over very long distances, as they are to be bridged, for example, in open-end spinning machines with several hundred jobs. In such machines, for example, from a central drive, the drive power can be transmitted via one or more drive belts to the distributed over the entire machine length jobs.
  • the drive means is a drive shaft.
  • the drive energy to be provided is transmitted via a rotating longitudinal shaft. Also in this embodiment, it is possible to transmit the drive energy over very long distances.
  • the drive energy transmitted by the drive shaft to each workstation is then preferably to be removed from the drive shaft in the vicinity of the respective workstation.
  • a transmission such as a friction or bevel gear is provided, which decreases the driving force from the drive shaft and introduces into a drive axle of the traversing device.
  • the bevel gear allows the drive energy slip-free from the drive shaft to remove.
  • the drive power is removed by means of drive belt from the drive shaft.
  • friction gear available, which can also be used and are cheaper to manufacture.
  • the drive axle is frictionally or positively engaged with a drive belt embodied as an endless belt and thus transmits the drive force.
  • a drive belt embodied as an endless belt and thus transmits the drive force.
  • the drive axle to be driven can be particularly simple by frictional or positive locking of this in the continuous movement, the driving force and thus reduce the drive energy.
  • the motion converter consists of a second drive means, which is preferably designed as an endless belt and is clamped between at least two deflection axes substantially parallel to the traversing direction to be driven, wherein at least one of the deflection axes is a drive axle and the endless belt a driver is attached, which carries out the movement of the endless belt, but it passes only the lying substantially in traversing motion components to the traversing device.
  • a motion transducer at each individual work site allows the drives and drive means, as well as the means used for power transmission, to operate in an undirectional direction of motion.
  • a particularly fast switching movement can be realized, which was technically very complicated to implement with conventional means, led to increased wear and due to the inertia of the device was only relatively slow to perform.
  • each machine side may have its own drive means. But it is also possible to divide one side of an open-end spinning machine in two, three or more groups, each consisting of a plurality of jobs. As a result, it is possible, among other things, only to shut down certain sections of the machine during batch changes, while in the remaining machine areas the production can be continued unchanged.
  • the motion converter is connected to a further drive means, which alternately moves this in different position states. For example, by rotating the motion converter about a rotation axis, the stroke amplitude can be changed.
  • a Hubver providedung so produced can be used specifically to build certain coil shapes, depending on how it requires the product to be produced.
  • thread guide means are advantageously arranged in front of and / or downstream of the take-off roller device, which can be deflected alternately parallel to the take-off roller surface via connected drive means.
  • the method further proposed by the invention is characterized in that the drive energy provided in the form of a unidirectional drive movement, then converted by means of a motion converter in an at least bidirectional movement direction and then transmitted to the traversing device, wherein the drive energy of a drive means to at least two Changier sexualen is divided.
  • FIG. 1 shows a traversing device 1 according to the invention, as used for example on open-end spinning machines.
  • the view is limited to the representation of the essential components of a winding unit.
  • a sleeve 2 on which a bobbin 3 is wound.
  • the sleeve 2 is to drive together with the winding body 3 by a drive roller 4, which acts on the outer circumference of the winding body 3.
  • Spool 3 and sleeve 2 together form a coil 5.
  • a traversing thread guide 6 arranged underneath takes on the task of subjecting a thread to be wound on the spool 5 to a traversing movement in the direction of the arrow 7. As a result, this leads to a hinted cross winding 8.
  • the drive according to the invention forms an electric motor, which provides the required drive energy for the operation of the traversing device 1.
  • a flat belt 9 which runs over rollers 10 in the direction of the arrow 11, is driven by the electric motor.
  • the drive belt 9 is an endless belt, the upper run 12 abuts the rollers 10 and moves to the left, while at the same time an associated Untertrum 13 moves in the opposite direction to the right.
  • the drive belt 9 shown here is designed as a flat belt. This means that the power transmission from the drive belt 9 takes place on the respective traversing device 1 by means of frictional engagement.
  • positive-locking means for power transmission can also be used here, such as toothed belts or chains.
  • the deflection axes are driven by an electric motor and adjustable in their longitudinal spacing, so that the drive belt 9 can be tensioned in this way.
  • positive drive belt 9 it is also possible in particular in positive drive belt 9 to arrange the introduction of force of the driving forces at any point of the drive belt 9. To ensure the permanent contact of the drive shaft 14 with the upper strand 12, such as at smaller angular deflections of the traversing device 1, this is pressed with the spring-loaded rollers 10.
  • the operation of the traversing device 1 provides a drive axle 14, which is cylindrical and is in contact with a portion with the surface of the drive belt 9. By a force exerted by the drive shaft 14 on the drive belt 9 compressive force, this, due to the present frictional engagement, driven.
  • the drive axle 14 is subdivided into three sections, which will be explained in greater detail below in FIG.
  • the drive shaft 14 drives a second drive means in the form of an endless belt 15 in the direction of the arrows 16.
  • a driver 17 is fixed, which rotates continuously with this.
  • the driver 17 is rotatably connected to a leg of an angled traverse arm 18.
  • the traversing arm 18 is substantially L-shaped and has a vertically arranged guide pin 19 approximately at the intersection of the two longitudinal arms.
  • the guide pin 19 in turn is guided in a substantially horizontally extending longitudinal groove 20 which extends within the traversing device 1.
  • the traversing arm 18 is thus mounted in two places. First, on the guide pin 19, which limits the possibility of movement to a purely horizontal movement. As a second bearing point of the driver 17, due to the deflection of the drive axle 14 and an associated abutment 21, next to the desired leads horizontal movement also makes a vertical move. As a result, the traversing arm 18 is simultaneously alternately reciprocated in a horizontal manner and rotated slightly to the left or right depending on the direction of movement about the guide pin 19.
  • the present traversing device is thus able to produce from a unidirectional movement of the drive belt 9, a bidirectional movement of the traversing arm 18 including the traversing yarn guide 6 attached thereto. Due to the very low mass also very fast traversing movements and direction changes can be performed. In particular, very rapid changes of motion in the edge region of the winding body 3 are possible with such a device.
  • FIG. 2 now shows a side view of the traversing device 1 according to the invention as shown in FIG. 1.
  • the drive roller 4 on which the spool 5 with the sleeve 2 and the yarn body 3 is located can be seen at the bottom.
  • the traversing yarn guide 6 guides a yarn 22 in the direction of the rotating spool 5.
  • the traversing device 1 is shown in a partially sectioned illustration.
  • the drive axle 14 is vertical.
  • the drive axle 14 itself is divided into three sections.
  • the first section is a drive section 23 and receives the drive forces or the drive energy from the drive belt 9.
  • the driving strand of the belt 9 is shown directly adjacent to the drive axle.
  • a bearing section 24 adjoins the drive section 23, followed by a driven section 25.
  • the bearing portion 24 is formed as a shoulder on the drive axle 14, which sits within a bearing 26.
  • the bearing 26 may be formed, for example, as a ball or roller bearings.
  • the overlying output section 25 is formed as a sprocket and is connected to the endless belt 15, which is designed as a toothed belt complementary shaped toothed belt in engagement.
  • the endless belt 15 of the driver 17 is attached, which engages in the traversing arm 18.
  • the guide groove 20 is shown in this view, within which the guide pin 19 acts as part of the bearings of the traversing arm 18.
  • FIG. 3 shows another embodiment of a traversing device 1 according to the invention, in which the provision or transmission of the drive forces or drive energies for the drive axle 14 is achieved in an alternative manner.
  • a drive shaft 27 which extends over the entire length of the textile machine, serves to transport the required drive energy to the individual traversing devices 1.
  • the drive shaft 27 rotates in the direction of arrow 28.
  • On the drive shaft 27 sits in the region of the drive shaft 14, a bevel gear 29.
  • the bevel gear 29 is provided with a helical toothing, which is complementary to a helical gear formed on the drive shaft 14 in engagement. About this helical toothing, the drive shaft 14 is driven.
  • the drive shaft 27 is now shown in a side view. Good visibility is also the bevel gear 29 with the illustrated teeth on the outer circumference.
  • the drive axle 14 has a drive section 23, which is designed as a bevel gear with a toothing formed complementary to the toothing of the bevel gear 29. In this way, the rotational movement of the drive shaft 27 is positively transmitted to the drive axle 14.
  • FIG. 5 shows two adjacent workstations of a spinning machine.
  • the coils 5 rest on drive rollers 4 and pick up the produced yarn 30 or the thread 22 according to the previous figures.
  • the traversing device 1 is rotatably mounted about a pivot point 31.
  • the drive of the rotary movement about the pivot point 31 via a push rod 32 which moves alternately and detects the traversing device 1 via a driver 33.
  • the push rod 32 has a thread guide means 34a, which deflects the yarn 30 immediately after a take-off roll 35, according to the movement of the push rod 32, laterally.
  • a further thread guide means 34b is arranged, which also deflects the yarn 30 laterally.
  • Both thread guide means are attached to push rods 32 which are connected via gear 36 with a motor 37.
  • By the lateral deflection of the yarn 30 in the area immediately before or behind the take-off roll 35 ensures that this alternately sweeps over the entire surface of the take-off roll 35 and thus a punctual wear is avoided.
  • a significant extension of the life compared to conventional take-off rollers 35 can be achieved.
  • the thread guiding means 34a or 34b is at the same time designed as a test device, such as a thread cleaner.

  • necessary or desired gear ratios between the speed of the drive belt 9 and the endless belt 15 can be adjusted if necessary.
  • This embodiment is particularly favorable when a stroke change is desired in addition to the traversing function.
  • Such Hubver can be particularly easily achieved by rotating the traversing device 1 about the pivot point 31, as has already been described above. Due to the coaxial arrangement of the drive shaft 14 and pivot point 31, a secure contact of the drive section with the drive belt is ensured in each deflected state of the traversing device 1.
  • the push rod 32 can be alternately moved back and forth along a linear trajectory, whereby the driver 33 is moved in a link 39 up and down. In this way, the drive of the rotational movement about the pivot point 31 occurs.
  • these embodiments can be removed or installed even when the drive belt 9 is running, so that the entire machine need not be shut down for repair work.
