- the winding head should be as compact as possible and for simple and rapid retrofitting of existing machines may be suitable.
- the object is achieved according to the invention in that the coil drive a distribution roller is formed, that the distribution roller and the thread laying each separate Have drive, both of which are connected to a common winding head control, and that the friction roller and the thread laying are structurally combined to form a winding head module and are mounted on a common support.
- the invention is therefore based on the new approach that only a noticeable cost reduction can be achieved if you use both thread laying and bobbin drives starts.
- the separate drives for thread laying and distribution roller enable maximum Flexibility of the winding head and the realization of the winding head as a module do not reduce only the costs, but also simplifies installation, operation and maintenance.
- the coil drive with the friction roller is compared to a direct drive of the spool especially at lower spool speeds cheaper.
- the inertia ratio of the friction roller from drive to coil significantly lower than with direct drive, so that drives are smaller Power can be used.
- DE-A-44 38 346 describes a textile machine for producing cross-wound bobbins, whose bobbin has a bobbin middle part and a bobbin upper part, wherein the upper part of the winder can be easily moved from an operating position to a waiting position is.
- the upper part of the winder is formed by a compact die-cast housing, in which all components necessary for the winding process are integrated. These components are in particular by a coil frame with a compensation device and formed by a thread guide drum.
- the thread guide drum also known as a grooved drum serves to drive the bobbin as well as thread laying.
- a first preferred embodiment of the winding head according to the invention is characterized in that that the winding head control is arranged on the common carrier.
- a second preferred embodiment of the winding head according to the invention is characterized in that that the distribution roller is attached directly to its drive.
- a third preferred embodiment is characterized in that the friction roller has a Has cavity in which the drive of the friction roller is arranged.
- a fourth preferred embodiment of the winding head according to the invention is characterized in that that the thread laying has a thread guide, which with a flexible, motor-driven traversing element is connected.
- the thread laying is preferably installed in a largely closed housing.
- the traversing element is guided over rollers and one of the rollers is a drive wheel for the drive of the traversing element.
- a fifth preferred embodiment is characterized in that the thread laying has an oscillatingly drivable thread laying lever mounted on an axis of rotation.
- the axis of rotation carrying the thread laying lever is dust-proof inside completed housing, which at least parts of the drive of the thread laying lever contains.
- the invention further relates to the use of said winding head and said Spooling head module on open-end spinning machines, such as rotor spinning machines.
- open-end spinning machines such as rotor spinning machines.
- the shown winding head modules differ essentially in the respective thread laying.
- 1 consists of an angled one Carrier 1, on which essentially a drive 2 for a friction roller 3, a drive 4 for a thread laying F with a thread laying lever 5 and a bobbin control 6 arranged are.
- the winding head controller 6 is connected to a power supply, not shown.
- the winding head module forms a compact structural unit that for example, a bobbin or an open-end spinning machine can be easily installed can.
- the carrier 1 can be designed such that in addition to its function as a carrier of the individual parts of the winding head module takes on additional functions, such as cooling.
- the friction roller 3 is provided for the non-positive drive of a coil 7, which to this Purpose rests on the jacket of the friction roller 3.
- the friction roller drive 2 is preferably so trained that his motor integrated into the hollow body of the distribution roller 3 and the distribution roller is fixed on the motor shaft, resulting in a very compact length of the friction roller drive system + Friction roller leads.
- the friction roller 3 because of its fixation on the motor shaft no own storage required, which leads to cost savings.
- the motor of the friction roller drive 2 is preferably a stepper motor.
- a motor-driven one can be used to drive the coil 7 instead of the friction roller 3 Spindle are used, on which the coil is attached.
- Such a direct drive is advantageous at high and very high winding speeds, whereas at lower ones Winding speeds, such as are the rule on rotor spinning machines, for example Advantages of the roller drive predominate.
- These advantages are mainly deeper Cost and in that the inertia ratio of the drive to the spool in the friction roller is significantly smaller than with direct drive, so that motors with lower power are used can be.
- Another advantage results from the use of a stepper motor for the friction roller drive because the stepper motor compared to a brushless asynchronous motor has a significantly higher torque at lower speeds.
- a speed sensor 8 or 9 is assigned to the friction roller drive 2 and the coil 7. Both speed sensors 8 and 9 are connected to the winding head control 6 and deliver the current speed data, from which, among other things, the thread length and the Coil diameter can be calculated. The latter is especially for the realization of from Coil laws depending on the coil diameter (wild winding, precision winding, step precision winding) required.
- the thread laying lever 5 sits on an axis of rotation 10 and points at it from the axis of rotation 10 distal end of a thread guide slot 11.
- the thread to be wound (not shown) runs from a supply spool or from a manufacturing or machining process via an arc plate 12 forming a control curve, which is indicated in the drawing by its contour is through the thread guide slot 11 to the bobbin 7.
- the mutual position of the thread laying lever 5 and arch plate 12 and the length of the thread guide slot are chosen so that the thread during the movement of the thread laying lever 5 the bottom of the thread guide slot 11 not touched. This ensures that the thread path from the arch plate 12 up to the coil 7 always the same, regardless of the diameter of the coil, Has geometry. Instead of the curved plate 12, a straight guide rail can also be used become.
- the thread laying lever 5 performs an oscillating, back and forth movement during operation and moves according to the laws of thread winding within a swivel angle of about 30 ° to 60 °.
- the axis of rotation carrying the thread laying lever 5 10 is in the interior of a dust-tight sealed housing (not shown, see here EP-A-1 044 917), in which a toothed angle segment 13 on the axis of rotation sits, which is driven via a toothed sweater 14 of the laying drive 4.
- the motor of the laying drive 4 is preferably formed by a stepper motor.
- the moments of inertia which are largely caused by the thread laying lever 5
- an inexpensive drive motor with relatively low power can be used.
- the incremental movement of the thread laying lever 5 improves by the reduction factor i.
- Reference number 15 denotes a mechanical stop for the thread laying lever 5, which serves as a reference point for the position of the thread laying lever 5. This reference point defines the starting position of the thread laying lever 5, relative to that for the Steps of the stepping motor of the laying drive 4 required for each stroke can be defined. Referencing must be carried out each time the winding head module is started up again , also whenever the thread laying F was without current or the stepper motor has lost its position.
- the winding head module can pass through the thread laying lever 5 the stroke-detecting sensor are supplemented (see EP-A-0 453 622) by the length of the Monitor hubs from the center of the stroke to the reversal points and correct any errors To allow errors in the lifting movement.
- This sensor can, for example, by a arranged on the angular segment 13 and a magnetic transducer assigned to it stationary scanner be formed.
- a stepper motor it is one Monitoring not required, because at most steps can be lost, the programmed one Hub would not be fully reached. If such errors are not corrected the system can be operated in open loop mode.
- the angle segment 13 can be designed as a gear segment and with the tooth puller 14 in direct intervention. For reasons of wear and damping, however, it is advantageous that Angle segment 13 not to interlock, but to equip with a toothed belt that with the tooth sweater 14 is engaged.
- the toothed belt is preferably not endless but as Belt piece formed, the ends of which are attached to the angle segment 13. With very few Double strokes of the thread laying lever 5 per minute, which is the case with parallel winders, for example if this is the case, a directly toothed angle segment 13 can also be used.
- the speed of the stepping motor of the laying drive 4 is determined by the winding head controller 6 changed over the stroke in such a way that a constant thread speed parallel to the axis the bobbin 7 also results when the thread laying lever 5 with its with the thread guide slot 11 provided end describes a circular path.
- the geometry of the arch plate 12 can be chosen so that at a constant speed of the thread laying drive 4 a constant Speed of the thread parallel to the bobbin axis results.
- the laying drive 4 can also be arranged outside the dustproof housing.
- the shaft of the toothpull 14 would pierce a housing wall, the Passage opening would be sealed with an O-ring.
- the arrangement of the laying drive 4 outside the housing has the advantage that the engine heat is better dissipated can.
- the control electronics can also be arranged outside the housing, the Sensor for the passage of the thread laying lever 5 through the center of the stroke through the housing wall works, which when selecting a suitable sensor, for example a Hall effect sensor, and a plastic case is not a problem.
- winding head modules in large numbers are used on the same machine, for example an open-end spinning machine, they are connected via a bus 16 to a bus controller 17, which is the interface forms between the winding head controls 6 and a host computer.
- the bus controller 17 has a terminal 18 for input and output of data.
