Definitions
- the present invention relates to a device for optimizing yarns and fabrics based on measured yarn data and the associated optimization process.
- CAD systems allow new tissues by changing a variety of developing parameters.
- Basis for the calculation in CAD systems are always "ideal" yarns, i.e. Yarns whose diameter, Fineness, tensile strength is constant over the entire yarn.
- a device according to the preamble of claim 1 is from EP-A-0 692 562 known.
- the object of the invention is to develop new tissue systems to improve and / or machine settings or processes in the Optimize yarn production.
- This object is achieved in that a device is provided which enables the real values of the respective yarn in the design of the fabric to take into account and at the same time an adjustment and / or change of the Binding or any intersection taking into account the optical Appearance of each yarn.
- the device according to the invention it is possible to change a to highlight any intersection of thin, thick or nits or optically to take a back seat.
- they are optical effects, which are achieved by irregular yarns, and the free definability of the binding enables the desired irregularities to emphasize this visually by the type of binding.
- the yarn diameter of the respective measure individual yarns optoelectronically. Due to the defined type of desired binding is taken into account taking into account the individual measurements
- a three-dimensional representation of the real fabric is calculated and visualized. Any crossing can - preferably via a schematic Representation of the fabric on a screen and input using the keyboard or a mouse - be changed.
- the real tissue can in turn be visualized and be changed until the desired design is obtained.
- the three-dimensional representation of the real tissue also becomes significant Amounts of yarn, machinery, electricity and labor saved as it no longer it is necessary to turn on the weaving machine to see how the real fabric looks like, to declare it as a committee if necessary.
- the combination of the binding input device also contributes to reducing the waste with the free choice of weaving density.
- the inventive Device also to measure and in the colors along a yarn to transmit the evaluation device so that in addition to the real yarn diameters the real colors are also taken into account when calculating the real fabric can be.
- the device 11 comprises a measuring device 12, which is used to measure the yarn diameter serves, a binding input device 13, in which the respective desired Binding freely defined and can also be changed, a control and evaluation device 14 and a display device 16, in particular a screen.
- the measurement of the yarn diameter in the measuring device 12 takes place in the measuring head, the works on the absolutely measuring optical principle.
- Advantage of absolute optoelectronic measurement is that the measurement is insensitive to Light source aging, extraneous light, pollution, temperature and humidity is and does not depend on the color, conductivity and gloss of the yarn to be measured. Also with such a measurement there is no constant new calibration and input of parameters required.
- measuring head In general, it is sufficient for the measurement of natural yarns to have a measuring head to be used, which measures with an accuracy of 0.1 mm. Depending on the type of measuring yarns, for example in synthetic yarns or in individual cases in natural fiber yarns, measuring heads with an accuracy of at least 0.01 mm.
- the measuring device 12 includes a yarn feed and electronics.
- Such measuring heads are known in the prior art and are used, for example distributed by BARCO / Belgium.
- the Accuracy of the yarn diameter measurement is at least 1/100 mm.
- the diameter of the yarn should be measured at least every 2 mm.
- the measured values determined in the measuring device 12 are now in the evaluation device 14 transmitted via a parallel interface 19.
- the evaluation device 14 controls the measuring device 12 at the same time via a serial interface 21.
- the device 13 is also free for input and change definable bonds.
- the binding input device 13 can any possible way of crossing the thread groups can be defined. Preferably these are flat weaves. By accessing already defined ones This device allows for an individual definition of bindings desired binding and a change to existing bindings any number of crossings. Entering and changing the respective binding The easiest way is via a PC by marking the respective one on a Crossing points displayed on the screen, for example with a mouse or over the keyboard.
- the binding input device 13 is together with the control and Evaluation device 14 integrated in a computer.
- the calculation takes place in the device 14 the three-dimensional representation of the real tissue due to the free defined binding and the measured yarn diameter.
- the representation takes place on a screen 16 connected to the evaluation device 14.
- An output device 17 can optionally be connected to the evaluation device 14 his.
- the measured data are visualized along room curves, with the brightness curve (Shadow effect) and color and a masking calculation the threads are carried out.
- the visualization light settings, Camera position and focal length can be changed.
- the display on the screen is preferably carried out by parallel projection of the Object using a 3D graphics library. However, there are other projections possible.
- the measured values can also be statistically evaluated.
- the statistical evaluation allows statements about the quality of the game.
- the statistical functions should include a statistical evaluation that is possible at any time of a single measured yarn also statistical evaluation over Totals of measurement series of individual yarns and / or freely definable and selectable Individual measurements of yarns include and mean values, standard deviations, Variances and other statistical evaluations of the measured Allow single yarns and / or groups of yarns. Also one is two and / or three-dimensional graphical representation of the respectively desired statistical functions intended.
- the calculation and / or visualization of the tissue partially and / or provided entirely with ideal yarns.
- the graphical representation of the three-dimensional real tissue can also be determined in certain selectable colors are made, with each yarn being assigned a color can be.
- the color selection is preferably carried out for any desired real and / or ideal Yarn by entering the desired red-green-blue values so that free definable and selectable colors are available.
- the device according to the invention also enables - for example for detection periodic errors, such as the moirée effect - the measured yarn in Form of a standard thread chart in the standardized dimensions on the screen to represent and also print out.
- the resolution of the screen 16 and / or the output device 17 should not be sufficient is a segmentation of the standard thread chart in For example, three segments are provided, which is also the case with hardware limited resolution allowed, the standard thread table in segments in the to represent the high resolution required to detect the periodic errors.
- the measured yarn data it is also possible to use the measured yarn data to have real knitted goods simulated, e.g. single jersey, right-right smooth, Right-right ribbed, interlock, piquet etc. or knitted.
- knitted fabrics and knitted fabrics can also be used in the binding input device Enter and change (13).
