Definitions

  • the invention relates to a textile machine, in particular a ring spinning machine or flyer, with at least one drafting system having a plurality of drafting system strands for forming at least one draft zone lying between two respective drafting system strands, at least two drafting system strings being associated with separate, in particular speed-controlled drive motors which are mutually switchable by means of an electronic control friction clutches are connectable to the drive cylinders of the relevant drafting system trains, and at least one gear is arranged in the drive train between the respective drive motor and the assigned drive cylinder.
  • the essential working elements are the spindles, the drafting units and the ring carriers or ring banks.
  • the speeds of the individual cylinders of the drafting system must be in a defined relationship to one another.
  • the ratio of the spindle speed to the delivery speed is decisive for the twist and the strength of the yarn.
  • the speed of movement of the ring rail and the ratio of this speed to the conveying speed are important for the formation of twine on the tubes.
  • every start-up or sequence control is necessary, in the course of which the working elements are to be switched up from a speed or speed in the range of zero to a specifiable speed or down to a speed in the range of zero , not entirely uncritical, especially since individual working elements of ring spinning machines can be controlled as separately as possible in order to achieve greater variability, and consequently rigid transmission connections should be largely avoided. Since the generally used speed-controlled electric motors can hardly be controlled in the lower speed range close to zero, they can also be controlled These drives cannot easily achieve the requirements that must be met for a constant yarn quality.
  • the aim of the invention is to provide a textile machine of the type mentioned at the outset, with which, even in the critical lower speed range and here e.g. Even during the critical phase of coupling, the means required for a constant yarn quality, such as, in particular, defined speed or speed ratios can be easily met with simple means.
  • each clutch is arranged between two gearboxes and in that the gearboxes arranged between the clutches and the associated drive cylinders have such gear ratios that torques occur on the load side of the various clutches which occur during clutching with the drive motors running For example, cause the drive cylinders to run up at least at a substantially constant speed ratio in accordance with the target delay which can be set via the electronic control.
  • the drive motors are only switched on to the loads via the couplings when the motors are synchronized with their supply frequency.
  • the engine speed can be monitored, for example, in order to couple the drive motors to the loads when these motors have reached a minimum speed when starting up, or to decouple the loads from the drive motors if the drive motors run at a minimum speed when the system is switched off.
  • the engine speeds and the control of the clutches can be effected from a common electronic control.
  • such a torque transmission can be provided between the motor and the load that the moment of inertia imposed on the motor when the load is switched on is in no way sufficient to in turn put this motor into a state in which the desired synchronization with the supply frequency is no longer provided.
  • the drafting cylinders are set in rotation at the same time despite the different loads with the speeds corresponding to the set delay and that the setpoint distortion values are maintained even when clutch slip occurs.
  • the transmission ratios of the gears arranged between the clutches and the associated drive cylinders are preferably selected such that at the load-side outputs of the various clutches there are at least essentially the same torques, in particular reduced to the smallest possible value.
  • At least some of the loads can be decoupled from these drives after a decrease in the speed of the assigned drives up to a predeterminable minimum speed and that at least the load with the greatest effective persistence can be braked depending on the time at which the loads in question are uncoupled.
  • the basic idea of this embodiment variant according to the invention is therefore to control the individual drives down to a minimum speed at which they can still be easily controlled, at least to decouple the loads with low persistence, which come to a standstill relatively quickly, from the loads in question, and decelerate the loads with greater effective persistence to maintain the target speed or speed ratios until standstill.
  • the risk of thread breaks occurring when the machine is switched off is therefore reduced to a minimum.
  • the load with the greatest steadfastness can preferably be braked at least substantially at the time when the relevant other loads are uncoupled. In principle, however, it is also conceivable to brake this load, which has the greatest effective persistence, somewhat before or after this point in time. It is essential that the desired speed or speed ratios of the respective working elements are practically maintained until standstill or the time within which deviations of these ratios from the target value can be as short as possible.
  • the braked load with the greatest effective steadfastness can remain coupled to the assigned drive until it comes to a standstill. Electrodynamic braking of this load is thus also possible, in particular, in that the assigned motor works as a generator for braking.
  • a braking resistor can be provided, which can be activated for the respective braking process.
  • the desired thread tension is to be maintained or the doffing process is to be facilitated after the machine has come to a standstill, it is expedient to fix at least the load with the greatest effective persistence after braking in its end position. In certain cases it can be advantageous if the respective end position of the load that has the greatest effective persistence can be specified.
  • the load with the greatest effective persistence is assigned a friction brake.
  • the drives of the respective drive system assigned to the loads are preferably each formed by a motor which is speed-controlled via a feed frequency.
  • a motor which is speed-controlled via a feed frequency.
  • synchronous motors, reluctance motors, speed-controlled or position-controlled synchronous motors as well as permanently excited motors can be used.
  • speed-controlled motors are particularly suitable for individual drives whose speed or speed relationships are to be strictly observed.
  • both switching on and switching off the loads should be done at low speed if possible.
  • the connection between the loads, in particular drive cylinders, and the associated drive motors can be established or interrupted at a predeterminable minimum speed of the drive motors, in which the synchronization of the drive motors which are speed-controlled via a supply frequency of frequency converters with this supply frequency is just ensured.
  • the brakable loads which have the greatest effective persistence are preferably spindles.
  • At least one load with a relatively low persistence in particular at least one drafting system strand of a drafting system, can expediently be decoupled from the assigned drive or connected to it. If several drafting system strands of a respective drafting system are driven, they can preferably be uncoupled simultaneously from the associated drives.
  • the effective steadfastness of the drafting cylinders is generally reduced to a minimum, in particular as a result of the gear ratio arranged between the relevant drive motor and the cylinder and the existing friction, so that the drafting system comes to a standstill practically immediately after uncoupling. Accordingly, the spindles must be braked accordingly quickly, so that the desired thread tension is maintained, but thread breaks are avoided.
  • the drive associated with the load with the greatest effective persistence comprises an electric motor operating as a generator in the event of a power failure for the emergency supply of at least one other drive.
  • the drives assigned to the other loads can be fed down to the minimum speed by the motor acting as a generator.
  • the respective drive systems preferably comprise separate drives for at least some of the loads
  • the drive systems are expediently assigned an electronic control system by means of which the speeds or speeds of the loads and / or the speed or speed relationships can be predetermined.
  • the electronic control preferably comprises a sequence control in order to control the drive motors, preferably in the event of a power failure, while maintaining predeterminable speed and / or speed conditions via frequency converters or the like, at least down to the lower speed range.
  • This sequence control in the event of a power failure expediently proceeds in the same way as the sequence of the textile machine during a normal shutdown.
  • Identical drafting systems and associated drives can be provided on the two machine sides.
  • the drives are expediently controlled down to a predeterminable minimum speed of the drafting cylinder or the drives.
  • the cylinders are then decoupled from the associated drive by means of the couplings.
  • the ring bench can preferably also be uncoupled from the associated drive.
  • the minimum speed selected here can be equal to the minimum speed at which the motors for starting up the drafting system are switched on to the drafting system cylinders.
  • a toothed belt and / or a gear transmission can be provided in the drive train between the load and the associated drive. Both a toothed belt transmission and a gear transmission are preferably provided, the toothed belt transmission being expediently arranged between the drive and the respective clutch and the gear transmission between the load, in particular a respective drafting cylinder, and the clutch.
  • the toothed belt transmission also serves as a damping device. This rules out that, for example, frequency-controlled three-phase motors emit torque pulses in certain operating states, particularly in the lower speed range, which can lead to damage in the drive train and, for example, a gearwheel transmission provided there.
  • the gear arranged in the drive train between the respective clutch and the assigned drive cylinder can be such a gear transmission. The desired alignment of the load moments of the various clutches is then effected via these gearwheels.
  • a brake is preferably arranged between the clutch and the cylinder-side transmission, by means of which for example, turning back the delivery cylinder after uncoupling can be avoided.
  • the drive cylinders can each extend over a multiplicity of spinning stations arranged on the relevant machine side, at least two drive cylinders being assigned two drive motors arranged at both ends thereof.
  • the drive trains of a respective drafting cylinder containing these drive motors are of identical design. If, for example, three drafting cylinders are provided, in particular the delivery cylinder and the feed cylinder can each be driven by a pair of drive motors, while the central cylinder is coupled to the feed cylinder via a change gear so that they run at a speed ratio predetermined by the change gear.
  • all drive cylinders can also be assigned in particular two drive motors arranged at their two ends.
  • the drafting system can comprise, for example, 3 or 4 drive cylinders.
  • a respective drafting train or drive cylinder is divided into at least two train parts arranged one behind the other in the longitudinal direction and the drive motors can be connected to a respective train part via a coupling.
  • the drive motors can be divided in the middle without the two cylinder sections, each driven by a motor, being coupled to one another.
