Definitions
- the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 11.
- the respective amount of yarn is determined and centrally evaluated by measuring the yarn speeds by means of special sensors in the yarn path.
- the yarn quantities in the masterpiece are compared to the knitted goods in order to determine and display incorrect uses, incorrect yarn speeds and incorrect machine operation cycles.
- non-positive delivery devices of different types with different yarn conveying principles and possibly from different manufacturers are used for different yarn qualities same knitting machine used.
- the monitoring and determination of individual amounts of yarn has so far not been possible with reasonable control and equipment effort.
- continuous, sequential or final information about the amount of yarn on knitting machines equipped in this way would be important for the operator and the specialist staff in order to assess and optimize production efficiency, to recognize drifting of production parameters during production, for upgrading, retrofitting and Readjusting to save time and effort, and to achieve quality optimization and consistently high quality with low waste.
- EP 0 752 631 A EP 0 950 742 A, EP 0 600268 A, DE 82 24 194 U, EP 0 420 836 A, EP 0 385 988 A, EP 0 489 307 A.
- Upgrading a knitting machine before production or after a changeover is extremely time-consuming and requires special expertise, especially if the knitting machine is equipped with non-positive delivery devices, possibly from different manufacturers, which also differ from one another in terms of their yarn conveying principles, because each The delivery device with its peripheral accessories that influence the yarn must be assigned to the respective knitting system and adjusted to individual optimal operation.
- easily obtainable information about the individual thread quantities would be invaluable, because with these delivery device types a thread quantity deviating from a specification can not only indicate an error condition or a trend, but also enables a direct conclusion on the type of error, which is then quick and goal-oriented would have to be corrected.
- the invention has for its object to provide a method of the type mentioned and an apparatus for performing the method with which despite Non-positive yarn delivery of delivery devices of different types, which work according to different funding principles, a simple and convenient production monitoring / setting is possible.
- each individual yarn quantity is measured continuously on the basis of sampled actual rotation signals of the delivery device, the actual rotation signals, taking into account the length of the storage body, result in sufficiently precise information on the amount of yarn without the absolute necessity of having to use separate sensors for this.
- Actual rotary signals resulting from the operation of the delivery device are used anyway.
- non-positive delivery devices in use on the knitting machine, which deliver yarns of different qualities and / or elasticities according to at least two different yarn conveying principles, and possibly come from different manufacturers.
- the individual thread quantities are precisely determined, which provide information on the production monitoring / setting.
- One reason for different types of delivery devices is that different yarn tensions and / or yarn speeds have to be mastered, for which one type is more suitable than another type.
- the individual yarn quantities are not primarily measured in the course of the method in order to obtain the total amount of yarn, but rather to show certain error conditions on the basis of the yarn quantities in order to be able to easily monitor and optimize the production. As a by-product, the total amount of yarn is then determined with little additional effort.
- the method is useful for circular knitting machines; can also be used in flat knitting machines. The process is based on the fact that the amount of yarn actually delivered, particularly in the case of delivery devices that do not deliver positively, enables conclusions to be drawn about correct operation in the knitting system, on the delivery device and in the yarn path and on trends relating to an error condition and even certain error conditions.
- the operation for each delivery device and on the associated knitting system can be monitored precisely, critical production conditions and even their causes can be determined, and measures can be taken during production or afterwards to correct error conditions.
- the method can be expanded by automatically correcting an error condition determined on the basis of the yarn quantity comparison, which is usually to be assigned to a specific type of error, for example in a closed setting control loop which uses the comparison result as a control variable.
- Such settings can be made on the knitting systems or the delivery devices or their peripheral accessories, because they only have an influence on the amount of yarn shown as a selection of operating elements and an error condition that occurs with them can be ideally represented using an inadmissible yarn amount change compared to the masterpiece yarn amount. It is important to adjust the width of the tolerance range used for the comparison even to yarn quality and / or yarn path parameters.
- the user on the knitting machine (circular or flat knitting machines) is given a user-friendly tool with a view to efficient production and short set-up times, in order to conveniently set the assignment pattern of the delivery devices from the inventory right on the user interface.
- each delivery device is fictitiously removed from the inventory, as it were, with regard to the yarn quality / elasticity to be supplied by it and relative position to the knitting systems and operationally assigned to the knitting system processing this yarn. This significantly simplifies the upgrade or conversion of the knitting machine, saves time and reduces the amount of work.
- the circular knitting machine is equipped with a sufficiently large inventory of non-positive delivery delivery devices, among which there are at least two different yarn conveying principles, the device sets the link between the delivery devices and the circular knitting machine required for efficient production, which is tedious Adjustment work on the delivery devices and / or in the machine control system can be reduced to a minimum.
- knitwear-specific assignment patterns are stored and used again if necessary or an assignment pattern formed in the user interface for a knitted fabric can be transferred to any further knitting machine producing the same knitted fabric.
- a keyboard or the like and / or the display designed as a touchscreen can be used as the input / display section of the unit.
- the yarn quantities are expediently measured using sensed actual rotation signals, e.g. calculated, and compared with corresponding target yarn quantities. Since under each delivery device type each comparison is only carried out for yarn quantities of one delivery device type, the yarn quantities of different delivery device types can be measured differently, so that a yarn quantity measurement value of one delivery device type does not initially correspond to the same yarn quantity measurement value of another type. Only when the total amount of yarn or a knitwear-specific amount of yarn is to be determined will a conversion or conversion to the same length or weight units be carried out. According to the method, each comparison with the masterpiece on the basis of the sampled actual rotary signals could, for example, to determine an individual error condition or trend, e.g. based on the type of signal 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 on which different types of delivery devices work simultaneously or in succession, with non-positive yarn delivery and at least two different yarn conveying principles. For example, less elastic yarn is supplied by a delivery device with a storage body driven to rotate, while more elastic yarn is supplied by a delivery device with a stationary storage body and winding device driven to rotate. These different types are also used selectively depending on the thread tension and / or thread speed.
- a circular knitting machine of this type is advantageous, for example, for so-called bodystockings or jacquard knitwear, but can also be useful for other high-quality knitwear in which different yarn qualities and / or differently elastic game are processed. This could also be done on flat knitting machines.
- an actual rotation signal is sampled per revolution of the storage body in a delivery device with a rotationally driven storage body, then 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 rotary signals per revolution of the storage body, each of which represents the same partial circumferential length of the storage body. In terms of control technology, this is carried out, for example, by scanning the rotation of the drive motor.
- a multiplicity of actual rotary signals representing the mutually identical lengths of the turns is expediently sampled. Since, in the case of a very elastic yarn, the turns on the stationary storage body can be stretched, the measurement is more accurate when the drawn-off yarn generates the actual rotation signals.
- the method it is favorable to set the width of the tolerance range used for the individual comparison larger, for example, with a more elastic yarn than with a less elastic yarn, since yarn path parameters have a greater influence with 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 a plurality of tolerance ranges of increasing width.
- a narrow tolerance range a trend can first be mapped from the comparison with the Masterpiece thread quantity curve, in order to derive an alarm signal if necessary, which causes the specialist staff to particularly monitor the thread path, the delivery device or the knitting system.
- the next wider tolerance range can be used to derive a setting measure when exceeded.
- the specialists then make manual settings 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 error condition that cannot be rectified immediately.
- yarn path conditions for example based on the yarn tension
- the yarn tension which is also important for the control of the drive motor, could be measured on the take-off side and used, for example, to adapt the actual rotation signals with regard to very precise yarn quantity measurements.
- the operations of the delivery devices assigned to the knitting systems during the production of a knitted fabric can be continuously shown on the basis of their individual thread quantities in comparison with masterpiece thread quantities, preferably within e.g. tolerance ranges dependent on the yarn quality and / or the respective yarn conveying principle. This can expediently be achieved with image bars representing the amounts of yarn. The bars are assigned to the addressed or identified delivery devices and their knitting systems. A condition running out of the tolerance range can be highlighted and e.g. be made clear with a flashing signal or even acoustically.
- Knitting machines of this type that have already been in operation can easily be retrofitted with the production monitoring / setting device.
- the device is then expediently positioned in a housing next to the knitting machine or in a section of the knitting machine foot.
- the production monitoring / setting device with its display and the input / display section can be integrated in the knitting machine control. This is useful to be able to use the same controls and the display of the controller.
- delivery devices with a rotationally drivable storage body are used for less elastic yarns and delivery devices with a stationary storage body, rotatable winding element and take-up side thread counting sensor device for more elastic yarns.
- Different knitwear To be able to produce it is advisable to provide an inventory of delivery devices on the knitting machine that is larger than the number of delivery devices that work in production.
- the device expediently also allows a user interface to be configured in which the total yarn quantity / individual yarn quantities or weights for one or more knitted goods produced can be represented in lengths and / or weight units.
- the delivery devices can be permanently connected via an interface adapter or optionally connected to the bus.
- the adapters at least for some of the delivery devices used, are designed in such a way that they derive the required actual rotary signals for the yarn quantity measurement directly on the delivery device or from pulses that are already available due to the operation.

- Non-positive yarn delivery means that there is no fixed correlation between the working speed of the cylinder and the speed at which the respective delivery device delivers the yarn, but that the respective yarn tension is kept essentially constant, but the individual amount of yarn varies compared to positive delivery, in which the thread tension varies, but the quantity delivered remains constant.
- the at least two different yarn conveying principles that are used for the intended delivery devices e.g. means that there are different braking and deflection conditions in the yarn paths, and with one yarn conveying principle yarn turns are temporarily stored on a storage body driven for rotation, while with the other yarn conveying principle they are temporarily stored in turns on a stationary storage body and the yarn is unwound depending on consumption. This will be explained with reference to FIG. 2.
