Definitions
- the invention relates to a method for delivering threads to a textile machine and a thread delivery device.
- a number of textile machines require several thread delivery devices for the production of textile goods, for example textile fabrics using the weaving or knitting method, which deliver threads to different thread consumption points.
- the thread delivery device has the task of pulling the thread from a thread spool and making it available to the knitting machine. So-called positive four Known engineers who have a yarn delivery wheel wrapped in the yarn, the rotation of the yarn delivery wheel determining the yarn delivery to the subsequent machine.
- Such a yarn delivery device can be found in US-PS 3858416.
- the yarn delivery device has an electric motor with a yarn delivery wheel, which is wrapped in the yarn to be delivered.
- the thread running from the thread delivery wheel runs via a thread tension sensor to a knitting point of a circular knitting machine.
- a position or speed sensor is arranged on both the knitting machine and the electric motor of the thread delivery wheel.
- the control circuit that operates the motor can now be connected to the position sensors via a changeover switch or alternatively to the voltage sensor.
- the motor rotates at a speed proportional to the working speed of the knitting machine. Thread is delivered to the knitting machine with a fixed amount of thread per machine revolution. For a given working speed of the knitting machine, the delivery speed is constant.
- the thread tension sets itself freely within wide limits. This operation is called positive operation.
- the alternative operating mode which is achieved by switching the switch block, is called live operation.
- the drive motor of the thread delivery device is controlled so that the desired thread tension is set.
- the amount of thread delivered to the thread-consuming machine is freely adjustable within wide limits. With knitting machines or other textile machines, it is often important to deliver several threads in parallel in such a way that uniform stitch sizes are created.
- the stitch size of the stitches to be produced is determined in a more or less random manner. Proceeding from this, it is an object of the invention to provide a method for supplying threads to a textile machine and a corresponding thread delivery device for supplying a plurality of threads to thread consumption points, with which a knitted fabric with a uniform stitch size can be produced.
- thread delivery devices are operated in a tension-controlled manner in one or more test phases.
- the thread delivery devices try to deliver thread with a predetermined thread tension.
- individual thread delivery quantities or thread delivery speeds are created on the individual thread delivery devices.
- These thread delivery quantities or thread speeds are recorded and the determination of a setpoint, i.e. a speed specification or a thread quantity specification.
- the thread delivery devices receive a signal characterizing the speed specification or the thread quantity specification and then deliver the corresponding thread quantities. This forces the same stitch size at all knitting points connected to the thread delivery devices.
- the thread tensions are set differently on the individual thread delivery devices.
- the thread speed is constant at all knitting points in trial operation. This is the case when smooth goods are produced. However, if patterned goods are produced, the thread quantity fluctuates. The fluctuation can be correlated with the rotational position of the needle cylinder and / or with the data of a sample memory. In these cases, the central unit also receives signals that correspond to the rotational position of a circular knitting machine and / or default values from the sample memory. In trial operation, the central unit then determines the nominal thread speed for each working section of the knitting machine in which the thread take-off of the knitting points is constant, on the premise that knitting points are taken from the general averaging without thread taking. Rather, they are recognized as temporarily inactive knitting spots. Accordingly, the thread speed setpoints of the thread delivery devices assigned to them are set to a low setpoint or zero.
- thread quantity specifications leading the production phases can be calculated.
- This procedure can affect all yarn delivery devices of a knitting machine or another textile machine.
- the thread delivery devices are grouped together, the procedure mentioned being used individually for each group.
- the thread delivery devices combined into a group are preferably those which are to carry out a thread synchronous delivery. If patterns are to be generated which require that a group of yarn delivery devices temporarily suspend or deliver different yarn speeds than one yarn delivery device other group, this can be easily achieved by supplying the thread delivery devices with the corresponding speed setpoint signals.
- the individual thread delivery devices of each group can carry out a real positive operation and still implement intermittent thread deliveries. For this purpose, they can be supplied with a repeat signal and / or with a needle signal, for example, and thus synchronized with the knitting machine or other textile machine.
- Corresponding control signals can be generated by reading out and processing sample data from a sample memory.
- the thread delivery devices can transmit a thread quantity signal to the thread delivery devices which identifies the thread quantity per machine revolution.
- the thread delivery devices continuously receive signals from the central unit or another location which determine the machine speed. From this and the previously received thread quantity signal, the thread delivery devices then continuously determine the required thread speed and regulate it. The thread delivery devices then run synchronously phase-locked with the machine. If individual thread delivery devices are to stop or deliver other thread quantities, the central unit sends appropriate signals to the thread delivery devices.
- the matching target voltages preferably apply to a group of yarn delivery devices that are later to be operated synchronously.
- the thread quantities or thread speeds provided by the thread delivery devices in the test phase are preferably delivered to a central unit as a signal in the form of digital data. This forms an average value and outputs this again as the nominal speed to the thread delivery devices combined in the group. With this procedure, the data traffic on the communication lines between the thread delivery devices and the central unit is reduced to a minimum. Once the thread delivery devices have received their thread speed setpoint, they save it and deliver at the corresponding thread speed. Further data transmission is only necessary if the thread delivery quantity is to be changed. If you have received a thread quantity setpoint, you need a speed signal for the machine speed.
- the thread speed to be determined during the trial phase is determined only on a few thread delivery devices of a group of thread delivery devices. This applies in particular to relatively large groups and in cases in which there are only slight deviations in the delivery speed within a group of yarn delivery devices.
- the evaluation can take place in the form of averaging, the mean value being both an arithmetic mean value and a geometric mean value as well as an average value formed according to other regulations. For example, thread speeds of individual devices can also exceed or be underweighted if they deviate too much from the other group average.
- a first test run can take place after the thread speed specification has been formed as the geometric mean of the individual thread speeds. If, in a subsequent thread speed-controlled test operation, the thread tensions that result are unsatisfactory, ie are too far apart, the thread speed specifications can be recalculated again in a second process, for example by trying an arithmetic mean and then testing in a new test operation to determine whether thread tensions are now closer together. If this is not the case, another mean value, for example, can be formed, for example as a quadratic mean value for the thread speed, with which a new trial operation is then carried out.
- the delivery speeds of the thread delivery devices which show particularly high thread delivery speeds, can be overweighted. If, in trial operation, a given thread quantity or thread speed at individual knitting points shows a thread tension that is too high or too low, the weighting factors of the thread speeds can be adjusted when averaging. For example, high thread speeds can be underweighted if thread tension that is too low has occurred in speed-controlled operation. Conversely, they can Weighting factors of particularly high delivery speeds determined in voltage-controlled operation can be increased if excessive voltage peaks have occurred in the subsequent speed-controlled test operation.
- the trial phase runs in two stages.
- the thread delivery devices are operated under voltage control and the thread speeds are registered.
- a test operation with thread speed specification is carried out in a second stage to check the thread tensions that arise.
- Individual thread delivery devices that do not have a thread tension sensor can also be used. As slave devices, these yarn delivery devices take over the yarn delivery wheel speed of one or more master yarn delivery devices. This applies to both voltage-controlled and speed-controlled operation.
- FIG. 1 shows a textile machine with centrally controlled thread delivery devices in a schematic representation
- FIG. 2 shows a thread delivery device of the system according to FIG. 1 as a schematic block diagram
- FIG. 3 shows a modified embodiment of a thread delivery device as a block diagram
- Figure 4 shows the central unit of the system of Figure 1 as a block diagram
- Figure 5 is a flow chart to explain the function of the yarn delivery device according to the invention.
- FIG. 1 illustrates a thread delivery device 1 for supplying a plurality of threads 2 to a knitting machine 3 or another thread-consuming machine.
- the threads 2 are delivered in groups, in that four individual threads 4, 5, 6, 7 are delivered to the knitting machine 3 by a first group 8 of thread delivery devices 11, 12, 13, 14. Further threads 15, 15a, 15b are supplied to the knitting machine 3 by a second group 16 of thread delivery devices 17, 18, 19. Any thread delivery device
- the thread delivery devices 11, 12, 13, 14, 17, 18, 19 can receive commands at least in groups via the data bus 32 and individually send data to the central unit 31.
- FIG. 2 schematically illustrates the structure of the thread delivery device 11 as an example for all other thread delivery devices 12, 13, 14, 17, 18, 19. The following description therefore applies accordingly to all thread delivery devices:
- the thread delivery device 11 has a thread delivery wheel 33 which is wound in several turns by the thread 4 to be delivered to the knitting machine 3.
- the thread delivery device is connected to the drive shaft of a motor 34 which can be operated at different speeds.
- a motor 34 which can be operated at different speeds.
- the motor 34 is a permanently excited DC motor.
- the thread 4 runs over a movable element 35, for example a feeler pin of a thread tension sensor 36, which delivers a thread tension signal at its output 37.
- the thread tension sensor 36 is part of a thread tension regulator 38.
- the thread delivery devices 11, 12, 13, 14, 17, 18, 19 are positive thread delivery devices. This means that the thread delivery wheel is wrapped in several thread turns, preferably more than four thread turns, whereby the thread is conveyed without slippage. However, in some applications it is considered to be quite advantageous to allow a certain slip between the thread delivery wheel and the thread. This can be done by wrapping only a few turns, for example only two or three thread turns, around the thread delivery wheel.
- one or more fixed or movably mounted thread lifting elements can be arranged in the vicinity of the thread delivery wheel, over which one or more thread windings run.
- the thread lifting elements can, for example, be pins aligned essentially parallel to the axis of rotation of the thread delivery wheel.
- the thread delivery wheel under the thread can rotate faster, with the of the thread compared to the thread delivery wheel can occur or occurs both in the trial phase and in the production phase.
- the thread delivery wheel can turn 10% faster than the thread is delivered. If the thread lifting elements are fixed, ie cannot be adjusted by the thread tension, a predictable and reproducible slip generally occurs.
- the thread delivery device 11 contains a delivery quantity regulator, which is referred to here as the thread speed regulator 44.
- the actual thread speed signal can be tapped as a voltage signal at the output of the control amplifier 42 if the operating voltage of the motor 34 corresponds to its speed with sufficient accuracy.
- the idle speed controller 44 receives its nominal thread speed signal from the control unit 43. This is also supplied with a signal via a line branch 46 which corresponds to the thread speed. ,
- the control unit 43 has an input 47 which is connected to the data bus 32.
- the central unit 31 is illustrated in a simplified manner in FIG.
- the central unit 31 has a communication block 48 which both address individual thread delivery devices 11, 12, 13, 14, 17, 18, 19 and also send data to them Data can be received from these.
- the communication block 48 is connected to an averager 49, which is set up to average the numerical values provided by the communication block 48 and which the yarn delivery speeds of the individual yarn delivery devices 11, 12, 13, 14 and 17, 18, 19 of a group Mark 8 or 16.
- the communication block 48 can send signals to the individual thread delivery devices 11, 12, 13, 14 or 17, 18, 19, which in turn cause their control unit 43 to switch the respective switch blocks 41 in such a way that either the thread tension regulator 38 or the thread speed regulator 44 is active.
- the signal supplied by the averager 49 is fed to a multiplication block 51, which multiplies the signal formed by the averager 49 by a normalized engine speed signal. This is obtained via a corresponding reception block 52 which is connected to a speed sensor of the knitting machine 3.
- the multiplication block 51 supplies a signal to the communication block 48, which supplies the signal determined in this way as a thread speed setpoint signal to the thread delivery devices.
- An input device 53 is connected to the communication block 48, which serves to switch the thread delivery device 1 from trial operation to regular operation and to make other inputs. Further details can be found in the following functional description:
- the thread delivery device 1 is a positive delivery device, which also has a trial mode.
- the input direction actuated accordingly, so that the central unit 31 sends a test mode signal to the thread delivery devices 11, 12, 13, 14 of group 8 and / or to the thread delivery devices 17, 18, 19 of group 16.
- the switch blocks 41 of the respective thread delivery devices belonging to the group 8 or 16 referred to thus switch to the lower position illustrated in FIG. 2, in which the thread tension regulators 38 are activated.
- the central unit 31 now sends a thread tension setpoint signal which is given by the respective control unit 43 to the thread tension regulator 38.
- the thread tension regulator adjusts the desired thread tension on each thread delivery device.
- the averaged thread speed (thread delivery quantity per machine revolution) is used as the setpoint for the closed thread delivery devices 11, 12, 13, 14, 17, 18, 19 are used as a basis.
- the communication block 48 first sends a switching signal to the switch blocks 41 of the individual thread delivery devices 11, 12, 13, 14, 17, 18, 19. These thus switch on the thread speed controller 44. From now on, when the machine speed changes, the central unit 31 sends the thread speed signal generated in the multiplication block 51 to the connected thread delivery devices, so that they deliver thread quantities or thread speeds that match in groups.
- the thread tensions of the threads 4, 5, 6, 7 of group 8 can thus differ considerably from one another, but due to the positive delivery, i.e. the delivery of fixed thread quantities per unit of time reaches a uniform stitch size. The same applies to the threads 15, 15a, 15b of group 16.
- the receiving block 52 in FIG. 4 has an alternative task: it does not constantly calculate thread speed default values again on the basis of the machine speed, but does this only once at the end of the trial operation. This speed is then sent as a coefficient to the thread delivery devices 11, 12, 13, 14, 17, 18, 19 and stored there. The thread delivery devices then receive signals that identify the current machine speed. The conversion of the thread delivery speed of the trial operation to the current machine speed is then carried out in the control units 43.
- the thread delivery device 11 according to FIG. 2 can also contain a testing device 55 which detects the Tension sensor 36 detected thread tension continuously or as required checked. The entrance to the testing facility
- Figure 3 illustrates a further modified embodiment of the thread delivery device 11.
- the deviation consists in the detection of the speed of the motor 34 or the angular position of its thread delivery wheel 33.
- a thread delivery device 1 contains a plurality of thread delivery devices 11, 12, 13, 14 which are combined to form a group 8.
- the thread delivery devices 11, 12, 13, 14 work individually tension-controlled based on a predetermined thread tension value.
- the yarn delivery quantities or yarn speeds resulting on the individual yarn delivery devices 11, 12, 13, 14 are reported to a central unit. This calculates a group average from the reported thread speeds and sends this as a default value for the subsequent operation to the thread delivery devices 11, 12, 13, 14.
- the individual thread delivery devices 11, 12, 13, 14 can subsequently work in pure positive operation.
- the central unit 31 can use an input 57 both to identify the machine speed (speed) and to receive pattern signals by means of which the thread delivery devices of the respective groups 8 and 16 to be addressed are switched on and off or accelerated or slowed down.
