Definitions

  • the invention relates to a warp knitting machine with a knitting area in which the warp knitting machine produces a knitted fabric during a knitting process, with a thread feed area in which warp threads run during operation of the warp knitting machine before they are subjected to the knitting process in the knitting area, and with a system for monitoring a Goods quality of the knitted goods produced, the system for monitoring the quality of the knitted goods produced having an optical scanning device and a data processing unit, and the data processing unit being set up to generate an evaluation signal relating to the quality of the knitted goods.
  • Warp knitting machines have knitting tools that process the warp threads in a knitting process into a textile material, a so-called knitted fabric. This takes place in a knitting area of the warp knitting machine.
  • the warp threads pass through a thread feed area beforehand.
  • the knitted fabric is produced by a loop-forming process.
  • Warp knitting machines have several bars, a plurality of knitting tools being arranged on each bar. Since a large number of knitting tools can be moved simultaneously by means of a bar, a large number of loops are formed at the same time during the knitting process. Herein lies is the reason for the particularly high production output of warp knitting machines.
  • drop stirrups are occasionally used in warp knitting machines. During operation, each drop bracket rests against a single thread in the thread feed area. If the thread breaks, the drop stirrup assigned to it can lower, which triggers an error signal. Since each warp thread is assigned its own drop bracket, this approach is structurally very complex.
  • a system with a light barrier is out of the DE 34 01 582 A1 known.
  • a The warp thread breaks, then it is usually thrown out of the effective area and passes a monitoring area of the light barrier.
  • not all thread breakage errors can be detected by means of the light barrier, since not every broken warp thread necessarily passes through the monitoring area of the light barrier.
  • a fan should be provided during operation of the light barrier in order to blow the warp threads out of the thread feed area in the direction of the light barrier.
  • the invention is therefore based on the object of providing a warp knitting machine that reliably detects knitting errors such as thread breaks and interlacing errors, but also other quality deficits in the knitted fabric produced.
  • the object is achieved by providing a warp knitting machine of the type described at the outset, in which the optical scanning device is arranged so that it can capture a moving image of at least one warp thread in the thread feed area, the data processing unit being set up to determine a thread running speed from the moving image to determine at least one warp thread, the thread running speed in one Evaluate evaluation step and generate the evaluation signal as a function of an evaluation result of the evaluation step.
  • the thread running speed is evaluated.
  • the thread running speed is sometimes also referred to as the thread delivery speed. It describes the speed at which the warp thread is moved in the direction of the knitting area.
  • the thread running speed can also be negative for a short time in special cases.
  • the thread running speed of the warp thread permanently deviates from an expected thread running speed.
  • the data processing unit it is possible for the data processing unit to classify the quality of the knitted fabric as defective if the thread running speed of a warp thread deviates from a previously measured average thread running speed of the warp thread.
  • the optical scanning device preferably detects the warp threads in an area of the warp knitting machine which is arranged directly in front of the knitting area.
  • the optical scanning device is preferably a camera or a moving image camera.
  • the camera can be a line camera.
  • a laser scanning system can be provided for optical scanning of the warp yarn.
  • the data processing unit is responsible for assessing the quality of the knitted fabric.
  • the assessment can be carried out in different ways depending on the embodiment of the invention. It is thus possible according to the invention for a quality measure to be output with the evaluation signal. On the basis of the quality index, an operator can decide whether it is necessary to stop the warp knitting machine in order to make corrections.
  • the quality measure can be output at regular intervals. Alternatively, it can be provided that the Evaluation signal is only output if the quality falls below a predefined quality threshold. According to the invention, it is also possible for the warp knitting machine to be set up in such a way that it stops the knitting process when the quality falls below a predefined quality threshold.
  • the data processing unit is preferably set up to compare a time profile of the thread running speed of the at least one warp thread in the thread feed area with a movement profile stored in the data processing unit.
  • the course of the thread running speed over time reflects the measured thread running speed of the warp thread during operation at different points in time.
  • the movement profile reflects a desired course of the thread running speed of the warp thread over time.
  • the desired course of the thread running speed over time can have been determined by a measurement or else have been calculated. Too great a deviation of the course of the thread running speed over time from the movement profile indicates poor quality of the knitted fabric or a fabric defect.
  • the data processing unit can be designed in such a way that it generates an evaluation result that indicates a reduced quality of the knitted fabric or a defect in the fabric if a difference between the temporal course of the thread running speed and the stored movement profile exceeds a predefined limit value at one or more times .
  • a separate movement profile can be stored for different warp threads.
  • the data processing unit uses a synchronization signal from the warp knitting machine in order to compare the movement profile with the actually measured temporal course of the movement speed of the warp thread.
  • the knitting process is a cyclical process.
  • the synchronization signal can always be generated when this process starts again.
  • the synchronization signal can be determined by means of a measurement at different points on the warp knitting machine, but a measurement is preferably carried out on the main shaft.
  • the main shaft is a drive shaft arranged in a machine bed of the warp knitting machine, which drives the bars of the warp knitting machine.
  • the data processing unit is set up to receive patterning information via a data interface or an input means of the warp knitting machine, to calculate the movement profile from the patterning information and to store the movement profile in the data processing unit.
  • a desired pattern can be entered via an input means such as a keyboard or a touchscreen.
  • the patterning information can also be transmitted to the data processing unit via a data interface, for example a network interface or a reader for a data carrier.
  • the patterning information defines how guide bars of the warp knitting machine should move during operation.
  • the movement of the guide bars determines the pattern created in the knitted fabric during the knitting process.
  • the data processing unit calculates a time-dependent warp thread consumption and thus also a time-dependent thread running speed of the warp threads. This results in an ideal movement profile that is stored in the data processing unit.
  • the data processing unit is preferably set up to learn the movement profile of the at least one warp thread by analyzing the moving image of the at least one warp thread and to store the movement profile in the data processing unit. This is preferably done in such a way that the thread running speed of the at least one warp thread is determined during a complete pattern laying cycle. This results in the movement profile. According to the invention, measurements can be made and averaged over several pattern laying cycles in order to obtain the movement profile.
  • the data processing unit is set up to evaluate a speed difference between two warp threads in the evaluation step. For this purpose, a speed of a first warp thread and a speed of a second warp thread are measured in the thread feed area. The speed difference is calculated from this.
  • the procedure can be as follows: If the speed difference exceeds a predefined limit value, then this indicates a reduction in quality or a defect in the goods, and a An evaluation result is generated that indicates a reduced quality of the knitted fabric or a fabric defect.
  • speed differences of several pairs of warp threads are determined by the data processing unit.
  • the resulting speed differences can be averaged or added.
  • the data processing unit determines according to the invention whether the result of the averaging or the addition exceeds a predefined limit value.
  • the data processing unit is preferably set up to filter out an interference spectrum from a time profile of the thread running speed of the at least one warp thread, to isolate at least one frequency peak from the interference spectrum and to compare a frequency and / or an amplitude of the at least one frequency peak with reference data.
  • Measurements have shown that the course of the thread running speed of the warp thread over time is not exclusively dependent on the pattern of the knitted fabric. Vibrations in components of the warp knitting machine can have a strong influence on the thread running speed of the warp threads. The action of the knitting tools - which are themselves subject to vibrations - on the warp threads influences the course of the thread running speed over time.
  • the quality of the knitted fabric can be determined by analyzing the frequencies that occur.
  • an interference spectrum is filtered out from the course of the thread running speed over time. This can be done, for example, by means of a Fourier analysis or in another suitable manner respectively.
  • the interference spectrum includes frequencies that typically lead to product defects.
  • the interference spectrum differs from machine to machine and can be determined by measurements. Individual frequency peaks are isolated from the interference spectrum and then compared with reference data.
  • the reference data describe properties of at least one frequency peak that is typical for the occurrence of a specific product defect. If there is sufficient correspondence between the reference data and an isolated frequency peak, then the data processing unit generates an evaluation signal which indicates a defect in the knitted fabric or a reduced quality of the knitted fabric.
  • the invention also relates to a method for checking the quality of a knitted fabric in a warp knitting machine.
  • the method has the following steps: acquisition of a moving image of at least one warp thread in a thread feed area of the warp knitting machine, determination of a thread running speed of at least one warp thread in the thread feed area, evaluation of the thread running speed in an evaluation step and generation of an evaluation signal relating to the quality of the knitted fabric as a function of one Evaluation result of the evaluation step.
  • This method can be applied to the warp knitting machine described above.
  • a time profile of the thread running speed of the at least one warp thread in the thread feed area is preferably compared with a movement profile. It is advantageous if the movement profile is calculated from pattern design information before the evaluation step. Alternatively, it can However, before the evaluation step, the movement profile can also be learned by analyzing the moving image of the at least one warp thread.
  • a speed difference between two warp threads can be evaluated in the evaluation step.
  • an interference spectrum is filtered out from the temporal course of the movement speed of the at least one warp thread, at least one frequency peak is isolated from the interference spectrum and a frequency and / or an amplitude of the at least one frequency peak is compared with reference data.

  • This system can be used in the warp knitting machine according to the invention.
  • the optical scanning device is provided in this system to capture a moving image of at least one warp thread in a thread feed area of the warp knitting machine and the data processing unit is set up to determine a thread running speed of the at least one warp thread from the moving image, to evaluate the thread running speed in an evaluation step and to generate the evaluation signal as a function of an evaluation result of the evaluation step.
