  • the invention has for its object to provide a method of the type mentioned above and an apparatus for performing the method, which despite non-positive yarn delivery of delivery devices of different types, which operate according to different delivery principles, a simple and comfortable production monitoring / adjustment is possible.
  • each individual yarn quantity is continuously measured on the basis of sampled actual rotational signals of the delivery device, resulting from the actual rotational signals taking into account the storage body circumferential length sufficiently accurate yarn quantity information without the absolute need to use separate sensors for this purpose. It will be used anyway from the operation of the delivery device resulting actual rotation signals.
  • non-positive delivery devices are used on the knitting machine, which supply yarns of different qualities and / or elasticities according to at least two different yarn conveying principles, and possibly originate from different manufacturers.
  • the individual yarn quantities are precisely determined, which provide information for production monitoring / adjustment.
  • One reason for different types of delivery equipment is that different yarn tensions and / or yarn speeds must be mastered, for which one type is better suited than another type.
  • the process does not primarily measure the individual amounts of yarn in order to obtain the total amount of yarn, but to show certain error conditions based on the quantities of yarn in order to easily monitor and optimize the production. As a by-product is then determined with little additional effort and the total amount of yarn.
  • the method is useful for circular knitting machines; but can also be used in flat knitting machines.
  • the process is designed to ensure that the actual amount of yarn delivered, in particular for non-positive delivery equipment, allows for proper operation in the knitting system, on the delivery device and in the yarn path and on trends to fault condition and even to certain fault conditions.
  • the operation for each delivery device and the associated knitting system can be closely monitored, critical production conditions and even their causes can be determined, and measures can be taken during production or thereafter to correct error conditions.
  • the method can be extended by automatically correcting an error condition determined on the basis of the yarn quantity comparison, which is usually attributable to a specific type of error, for example in a closed setting control loop which uses the comparison result as the control variable.
  • Such adjustments can be made to the knitting systems or the delivery devices or their peripheral accessories, because they only influence the amount of yarn represented as a selection and an error condition resulting from them can be ideally represented by an impermissible amount of yarn change with respect to the amount of masterpiece yarn. It is important to even match the tolerance range used for the comparison in its width to yarn quality and / or yarn path parameters.
  • each delivery device is, as it were, fictitiously removed from inventory with regard to the yarn quality elasticity and relative position with respect to the knitting systems to be supplied by it and assigned to the knitting system processing this yarn.
  • the upgrade or conversion of the knitting machine is greatly simplified, time is saved and reduces the workload.
  • the apparatus sets the necessary link between the delivery equipment and the circular knitting machine for efficient production. whereby tedious adjustment work on the delivery devices and / or in the machine control can be reduced to a minimum. It is obvious that knitwear-specific allocation patterns are stored and used again when needed or a mapping pattern formed in the user interface for a knitted fabric can be transferred to any further knitting machine producing the same knitwear.
  • input / display section of the unit for example, a keyboard or the like. And / or designed as a touchscreen display can be used.
  • the yarn amounts are measured with sampled actual rotation signals, e.g. calculated and compared with corresponding Sollgarnmengen. Since each comparison is made only for yarn quantities of a delivery device type among various types of delivery devices, the yarn quantities of various delivery device types can be measured quite differently so that a yarn quantity measurement of one delivery device type initially does not correspond to the same yarn quantity measurement of another type. Only when the total amount of yarn or a knitting yarn quantity is to be determined, will be a conversion or conversion to the same length or weight units. Thus, according to the method, to determine an individual error condition or trend, any comparison with the masterpiece could be based on the sampled actual rotational signals, e.g. be carried out on the basis of the signal type and / or number of signals and / or signal frequency, before real yarn quantities or yarn weights are determined.
  • the process is primarily geared towards knitwear production in circular knitting machines, in which different types of delivery devices work simultaneously or sequentially, with one non-positive delivery of yarn and at least two different yarn delivery principles. For example, less elastic yarn is supplied by a delivery device having a storage body driven for rotation, while more elastic yarn is supplied by a stationary storage body delivery device and a rotation driven winding member. These different types are also selectively used depending on the yarn tension and / or yarn speed.
  • Such a circular knitting machine assembly is advantageous, for example, for so-called Bodystockings or jacquard knitwear, but may also be useful for other high-quality knitwear, in which different yarn qualities and / or different elastic yarns are processed. This could also be done on flat knitting machines.
  • an actual rotation signal is scanned in a delivery device with a rotation-driven storage body per revolution of the storage body, this represents a quantity of yarn corresponding to the circumferential length of the storage body.
  • this is also possible to sample a predetermined number of actual rotation signals per revolution of the storage body, each of which represents the same circumferential partial length of the storage body. In terms of control technology, this is simple, e.g. performed by sensing the rotation of the drive motor.
  • the width of the tolerance range used for the individual comparison is favorable, for example, to set the width of the tolerance range used for the individual comparison to be greater with a more elastic yarn than with a less elastic yarn, since yarn path parameters have a greater influence on a more elastic yarn.
  • an individual yarn quantity comparison can be carried out not only within a tolerance range, but successively or in parallel in several tolerance ranges of increasing width.
  • a narrow tolerance range from the comparison with the Masterpiece Garnmengenverlauf initially a trend can be mapped to derive an alarm signal when needed, which causes the specialized staff to monitor the yarn path, the delivery device or the knitting system.
  • the next wider tolerance range can be used to derive an adjustment measure when exceeded.
  • the qualified personnel then make manual adjustments in the yarn path, on the delivery device or on the knitting system, or such adjustments are even initiated automatically.
  • the largest tolerance range is used, for example, to switch off the knitting machine, because this indicates an immediately unrecoverable error condition.
  • yarn path conditions e.g. based on the yarn tension, continuously monitored and used for example to adjust the width for the comparison tolerance range used and / or for editing the sampled actual rotation signals.
  • the yarn tension which is also important for the control of the drive motor, could be measured at the take-off side, and e.g. be used to adjust the actual rotation signals in view of very precise yarn quantity measurements.
  • the operations of the knitting systems associated with the knitting systems in the production of a knitted fabric can be represented on the basis of their individual yarn quantities in comparison with masterpiece yarn quantities, preferably within e.g. of the yarn quality and / or the respective Garn personallyzel dependent tolerance ranges. This can be conveniently realized with the image amount representing the yarn amount.

  • Non-positive yarn delivery means that there is no fixed correlation between the operating speed of the cylinder and the speed with which the respective delivery device delivers the yarn, but the respective yarn tension is kept substantially constant, but the individual yarn quantity varies compared to positive delivery, where the yarn tension varies, but the delivered quantity remains constant.
