Definitions

• the invention relates to a twisting machine according to claim 1.
• Such twisting machines are usually referred to as wing twisting machines.
• a wing twister is e.g. described in "Melliand Textilberichte" 1975, Issue 6, p. 431, in connection with Fig. 3, Fig. 2.
• Wing twisting machines are used to twist a thread or to simultaneously fold and twist several threads. At the same time, the thread or threads are wound on a spool.
• the well-known wing twisting machines produce bobbins that are further processed by machine.
• the invention solves this problem in that a wing-twisting machine is designed in such a way that it is suitable for the production of balls and therefore combines the previously multistage process of shedding, twisting, winding and winding into a ball to one step.
• the invention combines the principle of the wing twister with a coil winding, in that the coil axis is arranged obliquely to the wing axis.
• the center of gravity of the resulting ball should preferably be in the wing axis, so that no unbalances occur during the winding process.
• the ball holder can be rotated in relation to the thread wing, but is braked.
• This brake is preferably designed to be adjustable, e.g. in that a friction wheel is provided at the end of the axis of the ball holder, on which a stationary brake vane with adjustable spring force rests. Furthermore, a laying drive is provided which e.g. can be designed as a reciprocating thread guide that receives its drive from the wing whorl.
• the laying can be done mainly by rotating the ball relatively slowly about its ball axis. As a result, thread essentially lies next to thread. It applies to all relocations that the laying drive is removed from the wing whorl, thereby. that the wing whorl has a sun gear with which a drive wheel of the laying gear meshes.
• the laying gear is rotatably mounted on the ball holder.
• friction wheels, gearwheels, worm gears and worms as well as belt drives are suitable as sun gear and wheels of the laying gear.
• the wing whorl and the ball holder are mounted on the side of the ball facing away from the thread feed. This results in the easy accessibility of the ball, a feature that is particularly important for private use and for small amounts of thread. It is also of particular advantage if the thread conveyor, in particular a conveyor roller, is also rotatably mounted concentrically to the wing whorl and preferably on and relative to it.
• this invention provides a solution for twisting a thread in a twisting machine with a freely rotatable winding spindle, such as a freely rotatable ball holder, with a certain predetermined twisting (twists per meter of thread length).
• a freely rotatable winding spindle such as a freely rotatable ball holder
• a certain predetermined twisting tilts per meter of thread length.
• the thread running onto the flyer is guided over a conveyor that rotates at a predetermined speed.
• the speed is in a predetermined ratio to the speed of the flyer drive.
• the conveyor roller can have its own drive.
• the conveyor roller can be driven synchronously to the wing whorl; this creates threads with a constant twist ratio.
• the conveyor roller can be driven synchronously to the wing whorl; this creates threads with a constant twist ratio.
• the conveyor roller has its own drive which can be set independently of the drive of the wing host.
• the conveyor roller is freely rotatable on the conveyor whorl and can be braked with an adjustable braking force.
• a constant twist can also be set here by the fact that the speed difference
• the invention provides a 15th special feature of the thread guide, which also provides very good accessibility for the ball holder. Namely, the yarn - coming from an input thread guide on the wing axis - is first passed over the twisted wing and on this past the ball. After, for example, half a loop of the conveyor roller, the yarn is back again
• the twisted wing can be designed as a pot in particular to reduce the air resistance and air noise.
• the thread initially receives more twists per unit length when it overflows over the twisted wing than on the ball.
• the thread is overturned before it runs onto the ball and it is largely free of twist on the ball, so that it no longer shows a tendency to curl even during processing. Exemplary embodiments of the invention are described below with reference to the drawing.
• FIGS. 1 to 4 and 4A show exemplary embodiments which differ in certain structural details which are still to be discussed.
• a motor 2 is mounted in the chassis 1, which drives the conveyor roller 4 and the wing whorl 5 via the drive belts 3.
• the wing whorl 5 is rotatably mounted in the bearing 22 of the chassis 1 in the wing axis 15.
• the conveyor roller 4 is rotatably mounted on the wing whorl 5.
• the twisted wing 19 sits on the wing whorl 5 and, when the wing whorl 5 rotates, bypasses the ball holder 8.
• the twisted wing is shown as an arm which extends essentially parallel to the wing axis 15 and circumscribes a cylinder jacket during its rotation. In the drawing, this representation allows a view of the ball spindle and the spindle drive. However, it should be pointed out that other designs for the twisted wing are also possible. Particularly suitable is e.g. a pot-shaped wing, which is attached with its bottom to the wing whorl 5 and allows free access to the ball and the ball holder 8 from above.
• the ball holder 8 is fastened on a ball holder axis 7.
• the ball holder axis 7 penetrates the wing whorl 5 concentrically, but is independent of the rotational movement of the wing whorl 5.
• the ball holder axis 7 is also rotatably mounted in the chassis 1 in bearing 23. At its end there is a friction wheel 24, which can be adjusted by pressing a resilient brake vane 25 Brake adjustment 26 (adjusting screw) can be braked to a greater or lesser extent.
• the shaft 12 for receiving the winding core 9 is rotatably mounted about the axis 12 'on the ball holder 8.
• the twisted thread 11 is clamped in the groove 10 on the winding core 9 and wound into a ball 17.
• the shaft 12 and the winding core 9 are set in a slow rotation by the sun gear 6, which is a component of the Flugelwirbel 5, the intermediate gear 21 and the drive gear 20 with a strong reduction ratio.
• the exemplary embodiment according to FIG. 2 differs from that according to FIG. 1 in that a worm drive 21, 27 is provided in the gear train between the sun wheel 6 and the drive wheel 20 to achieve the necessary reduction. 3, the sun gear 6 is designed as a worm thread. The rotation is transmitted by a further worm 27 to the correspondingly designed drive wheel 20 of the winding core 9.
• FIG. 3 differs from the embodiments of Figures 1 and 2 also in that the drives 2.1, 2.2 for the
• Wing whorls 5 and the conveyor roller 4 are independent of one another, namely the wing vortex 5 is driven by the motor 2.1 and the conveyor roller 4 by the motor 2.2. Both motors can be driven at a constant, coordinated speed, i.e. 'synchronously with each other. Thanks to the variable speed ratio of the motors, yarns with different twist ratios (turns per meter) can be produced. However, it is also possible to change the speed ratio of these motors periodically or non-periodically during the manufacture of a ball, in order to thereby produce fancy threads which have different threads over their thread length. The speed ratio can also be changed by using only one .Motor 2 with variable speed gear.
• the conveyor whorl 5 is driven by motor 2.
• Motor and conveyor whorl are mounted in chassis 1.
• the whorl 5 is penetrated concentrically by the ball holder axis 7.
• the ball holder 8 is seated on the ball holder axis 7.
• the ball axis 12 is rotatably mounted thereon.
• the ball axis 12 is driven by the drive wheel 20. This drive is based on the sun gear 6, which is part of the Flugel whorl 5. This will be discussed later.
• the conveyor roller 4 is freely rotatably mounted on the wing whorl 5.
• the conveyor roller 4 can be braked.
• a brake band 32 is used for this purpose, which is firmly clamped on one side 33 and attracted by a magnet on the other side.
• the magnet 35 receives its current from a controller 36.
• This controller has a setpoint input 37 by means of which the twisting (rotations per meter of thread length) can be set.
• This setpoint is related in the controller to the current difference between the speeds of the conveyor roller 4 on the one hand and the Flugelwirbel 5 on the other hand. This difference represents the actual value of the twist.
• rev counter 38 are provided for the conveyor roller 4 and rev counter 39 for the wing whorl 5. Its output signal is given to the controller, which also takes over the formation of the difference value and the adjustment of the brake, so that the setpoint entered corresponds to the actual value of the twisting.
• Embodiment 4 is also characterized by the drive transmission transmission from the sun gear 6 to the drive wheel 20.
• the sun gear 6 is provided with a cam 28 or an eccentric.
• the movement of this cam 28 during one rotation of the Flugelwirbel 5 is transmitted to the filling lever 40 of a ratchet 29.
• the ratchet 29 is pivotally mounted on the ball holder 8 in the pivot axis 31.
• the front of the ratchet 29 is a leaf spring 30 which engages in the toothing of the drive wheel 20.
• a pawl is designated. This pawl serves the purpose of preventing the drive wheel 20 from turning back when the ratchet 29 executes its return movement under the force of an abutment spring (not shown) which lies in the pivot axis 31.
• a yarn 16 is produced from three threads that run towards the input thread guide 13 with the direction of travel 14. Hierzj ⁇ the yarn 16 is first fed into the thread guide 18 on the twine wing 19. From there, the yarn 16 runs onto the feed roller 4, loops around it and runs back onto the twisting wing 19, which has one or more thread guides 18 for this purpose. The yarn 16 then runs from the twisted wing 19 to the ball 17.
• the ball 17 is set on its ball holder 8 - as already described - in slow rotation. Characterized in that the ball axis 12 is inclined to the axis of rotation 15 of the twine wing 19, this slow rotation of the ball 17 causes the point of contact of the yarn 16 on the ball 17 to change constantly. This will place one layer of thread next to the other.
• the yarn 16 is thus laid in a manner similar to the traversing that is otherwise customary when winding.
• a special feature of the invention is therefore that the yarn 16 does not run directly from the twine wing 19 from the tangle 17. Rather, the yarn 16 is guided as follows: First onto the twisting wing 19, from there via a conveyor roller 4 arranged concentrically to the twisting axis 15 and driven at a controlled speed, and then back again over the twisting wing 19 and from there to the tangle 17.
• the thread runs which run towards the feed roller 4 and which run from the feed roller 4 are guided parallel, close to one another on the twisting wing 19. This is not necessary for the function. It is also possible, and in order to avoid unbalance, even to provide two opposing twine wings, the yarn then running on one twine wing to the conveyor roller and running on the other again from the conveyor roller and being fed to the ball.
• the thread can also loop around the conveyor roller several times.
• the twisted wing can be pot-shaped, the feed of the yarn to the feed roller running on the same or a different surface line of the pot as the return from the feed roller.
