Definitions

  • the invention relates to a yarn tension sensor, in particular for supplying elastic threads to knitting machines, a yarn feeding device for knitting machines and a method for adjusting a yarn tension sensor.
  • a yarn feeding device for elastic yarns which is intended for use on flat knitting machines.
  • the yarn feeding device is used to supply Elastanfäden and has a driven by an electric motor Fadenunterrad.
  • the electric motor is controlled by a control loop, which detects the current thread tension with a thread tension sensor.
  • This has a transversely to the thread running direction deflectable pin over which the thread is guided at an obtuse angle. The deflection of the pin corresponds to the thread tension and is detected by a suitable displacement sensor.
  • a yarn feeding device for knitting machines which also has a yarn feed wheel, which is driven by a motor.
  • the motor is controlled by a control loop that detects the thread tension with a thread tension sensor. This has a deflectable pin over which the thread runs.
  • a yarn winding apparatus with a yarn tension sensor is known.
  • an actuator device which periodically deflects the yarn to engage it with a yarn feeler for detecting the yarn tension. This measure is used to generate alternating signals on the sensor and to check the back and traversing thread only at preselected times with regard to its thread tension.
  • Such a thread tension sensor is not suitable for continuous thread tension monitoring on a running thread.
  • EP-A-0 406 735 discloses yarn tension monitoring by means of a yarn tension sensor, wherein in case of business interruptions the zero point of the yarn tension sensor is checked. Business interruptions arise when using the yarn tension sensor in a false twist device whenever a yarn package is fully wound.
  • the constant voltage is especially when supplying elastic threads to produce elastic knitted fabrics of great importance. Even the slightest fluctuation and especially long-term changes are reflected in a changing or changing quality. It is therefore important to keep the thread tension stable over long periods of time, ie hours, days and months.
  • Knitting machines and yarn feeding devices are often used in factories where, not least due to the heat loss of the knitting machines, the temperature changes during the day and according to the running time of the machines. This also changes the temperature of the thread tension sensors, which, despite possibly existing temperature compensation, can influence their output signal. In addition, in the long term, debris can result in a change in the sensor output signal, for example, when deposits on a yarn tension sensing pin increase the overall weight of the pen and thus shift the zero point of the signal.
  • a yarn tension sensor which allows a long-term stable detection of the thread tension.
  • a yarn feeding device is to be created, which delivers the thread, for example, in a flat knitting machine with a constant yarn tension.
  • a method for operating a yarn tension sensor in the application of which the sensor emits a reliable long-term stable output signal.
  • the yarn tension sensor according to the invention has, in addition to its yarn feeler element, which is in contact with the yarn for measuring the yarn tension, a thread receiving means, which is movably mounted. It has at least two different positions, which differ in that the thread is separated from the thread feeler element in a calibration position and bears against the thread feeler element in the measurement position of the thread takeup means. It is thus possible by targeted adjustment of the thread receiving means and / or the thread tension sensor to arbitrarily lift the thread from the yarn feeler element, so that this passes into its rest position. This is characterized in that no force acts on the yarn feeler element. The measuring device detects this position or this state of the yarn feeler element.
  • a drift has occurred in the mechanical or electrical system of the yarn tension sensor, this can be detected and detected by the yarn feeler when the yarn is lifted off.
  • the lifting of the thread can be used by the yarn feeler for zeroing the yarn tension sensor.
  • long-term offsets can be avoided, which would otherwise superimpose the output signal of the yarn tension sensor.
  • a sensor output signal is generated in the long term, which reproduces the yarn tension free of zero errors. This allows the construction of a yarn feeding device with high long-term stability of the thread tension.
  • the yarn feeler element and thread receiving means are arranged on opposite sides of the yarn path.
  • the thread receiving means "presses" the thread to the yarn feeler element; for calving it lets the thread lift off the thread feeler.
  • the yarn feeler element and thread receiving means are arranged on a same side of the yarn path.
  • the suture receiving means "pushes" the suture away from the suture sensing element and, for measurement, causes the suture to abut the suture sensing element.
  • the senor can be moved in each case in a first design, while in a second design, the thread-receiving element is movably mounted.
  • the calibration or zeroing operation is preferably performed when the yarn feeding device does not supply a yarn. In this period caused by the zero point adjustment or allowable thread tension fluctuations can not lead to an impairment of the knitwear produced here.
  • the drive signal of the motor is monitored. If an L-0 edge, i. a clear transition of the drive signal from a non-zero value to the value zero, it is assumed that the engine has been deliberately stopped.
  • L-0 edge i. a clear transition of the drive signal from a non-zero value to the value zero
  • a restart of the motor can be expected. The same applies to thread changes in stocking or sock machines.
  • a waiting time of, for example, 20 ms is now waited for and, if the drive signal is still zero after the expiry of this waiting time, the calibration process is allowed to take a few 10 ms.
  • the calibration process is then carried out when it is allowed (released) and (as a second criterion) when requested. This is usually the case at regular intervals.
  • the time intervals can be shorter after switching on the machine (2 min.) And longer after the running in (30 min.).
  • the yarn tension sensor preferably has a thread receiving means associated drive device, such as a pull magnet or other drive (electric or pneumatic rotary, swing or linear drive), which is activated by a calibration and drives the thread receiving means such that this in his first the Thread of that Thread feeler lifting position is transferred. Now the zero point adjustment can be carried out.
  • the drive device is deactivated, the thread receiving means arrives in its second position, in which the thread bears against the yarn feeler element.
  • the thread receiving means is in this position separated from the thread, that does not touch this.
  • measurement errors due to friction of the thread on the thread receiving means are eliminated.
  • it is also possible to consciously use the thread receiving means for thread guidance In the former version, the thread is engaged either with the thread take-up means or with the thread feeler element. In the second variant of the thread is always in contact with the thread receiving means, regardless of whether he is lifted from the yarn feeler element or not.
  • the thread receiving means is formed by a, preferably two adjacent to the yarn feeler Fadenholz commentary. These are in the simplest case pins that extend parallel to the preferably also pin-shaped thread feeler. It can also be used eyelets. Both the pin of the thread-sensing element and the pins of the thread-receiving means extend transversely to the thread running direction, preferably at right angles thereto. This ensures that even with relatively wide pins all thread positions on the pin are equal, so that the thread does not saw in a preferred location.
  • the yarn feeler element of the yarn tension sensor is preferably mounted on a spring parallelogram.
  • the preferably pin-shaped yarn feeler element is then arranged at right angles to the bending springs.
  • the measuring device preferably has two displacement transducers whose output signals preferably change in opposite directions upon deflection of the yarn feeler element. This enables an offset suppression in the evaluation circuit.
  • This is preferably a difference generator circuit, which may be formed by a bridge circuit or an operational amplifier or other appropriate means.
  • the yarn tension sensor according to the invention and the yarn feeding device according to the invention are to be used, for example, on a flat knitting machine, wherein said calibration or zero point adjustment process can be carried out, for example, when the yarn guide or yarn change direction is reversed. If, for example, the thread guide moves away from the yarn feeding device and stops at the end of its movement stroke, the required yarn delivery quantity, irrespective of the respective knitting pattern, is momentarily zero.
  • a separate calibration circuit can detect this and briefly activate the drive device, so that the thread is lifted off the thread feeler element and the resulting measured value can be detected as a zero point. Once this has taken place, the calibration circuit deactivates the drive device, so that the thread is placed on the thread feeler again. The entire process can be completed in a few ms to some 10 ms with appropriate design of the yarn tension sensor and the drive means for the thread receiving means. The existing during the reversal of direction of the thread guide downtime is thus sufficient to carry out the calibration.
  • the yarn feeding device can be operated at standstill of the knitting machine in a standby or standstill mode. If the yarn feeding device is led out of this state (switched on), the short-term calibration process can be carried out.
  • a yarn feeding device 1 is illustrated, the housing 2 has a substantially flat front side 3. At this a yarn feed wheel 4 and a yarn tension sensor 5 are arranged.
  • the housing 2 of the yarn feeding device which is provided with means not shown for attachment to a knitting machine, in particular a flat knitting machine, has, in addition to the yarn feed wheel 4, an eyelet 6 for guiding a merely illustrated by a section 7 thread.
  • the eyelet 6 is provided with an insert 8 made of ceramic and arranged with respect to the illustrated by an arrow 9 thread running direction in front of the yarn feed wheel 4.
  • a further eyelet 12 is arranged with a ceramic insert 13 following a signal lamp 11.
  • the yarn feed wheel 4 serves the demand-oriented conveying and delivery of yarn 7 and the yarn tension sensor 5 monitors the yarn tension. Accordingly, a control device arranged in the housing 4 controls, based on a signal supplied by the thread tension sensor, a motor for driving the yarn feed wheel 4.
  • the yarn feed wheel 4 is preferably formed six or Moflüglig and has a plurality of radially extending away from a hub 14 spokes 15, 16, which are each connected at the ends by a web 17 with each other. In each case a pair of spokes and a web 17 define a wing 18. The wings 18 are arranged at equal angular intervals.
  • the yarn feed wheel 4 therefore defines a polygonal outer circumference on which the yarn 7 rests as a regular hexagon.
  • the yarn feeding wheel 4 is followed by the yarn tension sensor 5, which has a pin 21 serving as a yarn feeler element. This extends transversely to the thread 7, which runs at an obtuse angle over the outer peripheral surface of the cylindrical pin 21.
  • the yarn feed wheel 4 is rotatable about an axis of rotation 22 which is not arranged parallel to a longitudinal axis 23 defined by the pin 21. Due to the inclination of the yarn feed wheel 4 with respect to the pin 21 and thus the yarn 7 4 advantageous conditions are achieved for the yarn when leaving the yarn feed wheel.
  • the thread is pulled off at a larger angle. This causes an exact detachment of the thread from the yarn feed wheel or other recorded from the yarn feed yarn turns.
  • the thread 7 runs at an acute angle to an imaginary plane 24 from (Fig.2), for which the axis of rotation 22 defines the normal direction. This is achieved by appropriate positioning of the eyelet 12.
  • the yarn tension sensor 5 is to be understood in particular with reference to FIGS. 3 to 5.
  • the pin 21 is mounted on the end of a low-mass carrier 27, which is held by two arranged in the manner of a spring parallelogram leaf springs 28, 29 movable substantially in the longitudinal direction.
  • the support 27 projects with cylindrical sections into damper pots or tubes 31, 32, which contain a more or less viscous liquid. This suppression is achieved in particular high-frequency signal components, which may occur, for example, due to the polygonal contour of the yarn feed wheel 4.
  • the torsion springs 28, 29 are at the end of corresponding receptacles 33, 34 taken, which are attached to a base 35. This is, as is apparent from Fig. 7, stored with a total of four preferably made of rubber damper elements 36 stationary.
  • the base 35 is, as shown in FIG. 4, for example, formed by a U-shaped yoke 35 a.
  • a permanent magnet 37 On the carrier 27, a permanent magnet 37 is arranged, whose magnetic field reaches and influences two Hall sensors 38, 39 arranged in the immediate vicinity. Even a small displacement of the carrier 27 with respect to the base 35 is detected by the Hall sensors 38, 39.
  • To the yarn tension sensor 5 includes a calibration device 40 having two thread receiving means 41 serving as pins 42, 43, which are arranged substantially parallel to the pin 21.
  • the pins 42, 43 are held on a support frame 44, which is movable with the pins 42, 43 transversely to the pin 21 in the direction of the arrow 45 ( Figures 3, 4 and 5).
  • the thread receiving means 41 is thereby convertible into at least two different positions. In a first position, which is shown in dashed lines in Figure 5, the pins 42, 43 are in a position in which they lift the thread 7 from the pin 21. In this position, no forces exerted by the thread 7 act on the pin 21.
  • the thread receiving means 41 is connected to a drive device 46.
  • the pins 42, 43 are held by a frame 47 which surrounds a solenoid coil 48.
  • Its magnetic coil 49 has a tie rod 51 connected to the frame 47.
  • the frame 47 is by appropriate guide means 52, for example.
  • In one Base plate 53 provided slots 54 or the tie rod 51 slidably mounted in the adjustment (arrow 45).
  • the frame is connected to the base plate 53 via a spring means 56.
  • the spring means 56 is preferably a leaf spring 57, which is held at one end to the base plate 53 and connected at its opposite end to the frame 47.
  • the Hall sensors 38, 39 which are only indicated schematically in FIG. 5, are, as illustrated in FIG. 9, connected to a measuring circuit 61, which processes output signals pending at outputs 62, 63 of the Hall sensors 38, 39.
  • the Hall sensors 38, 39 are arranged to emit opposing signals. If the carrier 27 is deflected in one direction, for example, the signal of the Hall sensor 38 increases, while that of the Hall sensor 39 decreases.
  • the measuring circuit 61 is designed as a subtractor circuit and includes an operational amplifier 65. This operates as a differential amplifier. The voltage gains at the non-inverting and inverting inputs are equal in magnitude but different in sign. This is ensured by a corresponding wiring.
  • TP1 and TP2 are connected upstream in the low-pass filter in order to suppress higher frequency components of the sensor signals.
  • a time averaged and amplified value of the difference of the output signals of the Hall sensors 38, 39 is present at the output.
  • the thread 7 changes periodically its angle to the pin 21. This caused fluctuations of the sensor signal are filtered out by the low-pass characteristic of the measuring circuit 61.
  • the yarn feeder 1 is provided with an automatic calibration or zeroing circuit. This is connected to the solenoid 49.
  • the yarn feeding device 1 performs its adjustment as follows:
  • a knitting machine not shown, which is provided with the yarn feeding device 1, does not work.
  • the yarn feeder 1 is turned off, but its electronic circuit is active. It is in a waiting mode.
  • the calibration circuit briefly activates the magnetic coil 41, which attracts the armature 51.
  • the frame 47 is advanced so far in the direction of the pin 21 that the pins 42, 43 pass the pin 21 and lift the thread 7 from the pin 21.
  • the pin 21 is now free of thread forces, and the signal output by the measuring circuit 61 in this state marks the zero point, i. the thread tension is zero.
  • control loop controls the motor in each case in such a way that the yarn feed wheel 4 delivers the amount of thread required for keeping the thread tension constant.
  • the avoidance of errors as a result of zero drift occurring after the commissioning of the yarn feeder 1 can be effected by the calibration process described is frequently made recurring. This is possible in particular in time windows in which, during the operation of the yarn feeding device 1, the yarn feeding wheel 4 and thus the yarn 7 come to a standstill. This state is characterized, for example, by a corresponding controller output signal (motor drive voltage equal to zero). To detect such time windows, the calibration circuit monitors the controller output signal. If such a time window is present, the only a few or a few tens of milliseconds calibration process is triggered, i. the solenoid 49 is briefly energized and the zeroing of the measuring circuit 61 is performed by the self-adjusting output is taken as zero value.
  • the flow chart 10 is according to Fig. Initially waiting for the interval time t a presettable COMP. elapses.
  • the time t abgl . is the time interval in which a zero balance is to be made. It lies between a few minutes and one Hour.
  • the controller output signal is first examined to see if it goes to zero. Thereafter, it is checked whether it remains at zero for a given time, for example 20 ms. If so, there is a time window and it is expected that the motor of the feeder has been deliberately stopped and stopped for a long time (500 ms). During such a time window, the adjustment can be performed.
  • the detection of the time window is preferably carried out edge-triggered.
  • an automatic adjustment in the carriage or thread guide reversal can take place, which is associated with standstill of the motor of the yarn feed wheel 4. If such a motor stop is detected, an automatic adjustment can be performed after a predetermined variable time. In this way it is possible to detect even short-term and relatively fast drifts within the overall system and render harmless.
  • a yarn feeding device 1 provided in particular for machines with intermittent yarn consumption and elastic yarns has a yarn tension sensor 5 which is provided with a calibrating device 40. This lifts the thread 7 at times from a belonging to the yarn tension sensor 5 pin 21, where this is possible without affecting the operation of the yarn feeding device 1. These are preferably time windows in which no thread delivery is required. If the thread 7 is lifted from the pin 21, a zero point adjustment is performed, whereby zero drift of the entire sensor system including its measuring circuit 61 can be detected and compensated.
