Description

Textile machine, especially a weaving machine

The present invention relates to a textile machine, in particular a webbing textile machine, according to the general concept of the first aspect of the patent application.

Textile machines, especially webbing machines, are known in the prior art. In general, the number of yarns conveyed by the warp yarns and/or weft yarns of the textile machine is nothing more than negative control, ie tension control, or mechanical forward adjustment to the processing position. The disadvantage of negative yarn control is yarn loading, especially when using yarns of various qualities and characteristics. For rubber yarns or yarns of its kind, it must be adjusted individually for negative control, otherwise the yarn may be subjected to harmful tension. For the fixed-mechanical forward mechanical control, the disadvantage is that the yarn feeding device can only work with a constant tensile strength, which can only be adjusted to the weakest yarn, so the quality of the textile is affected.

A textile machine is disclosed in the European patent application EP 1 526 199 A, which has individually independent transmission yarn delivery devices which can be individually controlled in accordance with the pattern, wherein only the tension in the yarn is controlled, individually General adjustments are not considered.

A knitting machine as known in the prior art WO 2004/111322, which is provided with a mechanical device with an electronic control device for controlling the input of the weft, which adjusts the individual yarns for the knitwear in production according to the pattern program. Transmission device. The knitting machine also includes a correction device by which the components of the knitting machine that function according to the pattern can be modified with an adjustable correction parameter.

A method for controlling the warp tension of a textile machine by controlling the driving speed of the warp thread and/or the finished textile roll is known from the patent application WO-A-88/05089. However, adjusting the weft tension or the number of wefts is not mentioned, seen or added in this document. Another method for venting and adjusting the warp yarns in a similar manner and in accordance with the teachings of the art is known from the patent application WO-A-91/05895, which is known by means of a control device, for example, provided with a button. However, adjusting the weft tension or the number of wefts is not mentioned, seen or added in this document.

The task of the present invention is to further improve the previously mentioned textile machine.

This task will be achieved by the features described in item 1 of the scope of the patent application. Therefore, a textile machine, in particular a webbing textile machine, is provided with at least one set of electrically driven yarn transporting means for at least one weft thread, a set of finished product delivery means for delivering the textile, and a set of electronic control means for utilizing the pattern Programmatically controlling the textile machine to produce textiles. The control device is provided with a control mechanism that automatically adjusts the length of the yarn fed to the weft yarns of at least one set of yarn transport devices to ensure that each weft yarn is applied and that each pattern is readily available. The necessary yarn length for precision. In this way, the weft yarn can be dispensed with, for example, from a conical yarn roll using a weft input device. Therefore, the general characteristics of the textile can be improved, and the structure of the textile fancy can be greatly improved. In the textile process, disturbances such as yarn breakage and weaving defects are greatly reduced. The length of the yarn feed can be calculated not only by the pattern of the pattern and by the delivery device of the finished product, but also by the variation width of the textile to be produced in the textile process. The practice of the invention thus also allows for such changes to be incorporated in the weaving process.

It is particularly advantageous if the textile machine is provided with an electrically driven yarn delivery device that drives a plurality of warp yarns. The control device is also provided with a control mechanism that automatically adjusts the length of the yarn fed by the yarn transfer device according to the preset data in the pattern. The warp yarn feed length of the yarn transport device is also calculated using the pattern of the pattern and the textile finished product delivery device and the width of the textile to be produced (item 2 of the patent application).

It is particularly advantageous to further develop according to the scope of claim 3, since the yarn feeding data of the weft yarn can be further corrected according to the function data of the pattern using the correction parameter K _S , which can be further adapted to, for example, yarn quality and/or Or the floral characteristics of the textile to be produced. Preferably, calibration parameters K _K and K _{W are} also provided for controlling the yarn delivery data of the textile finished product delivery device and/or warp (application patent item 4).

A particularly advantageous calibration device is provided with a set of display screens according to item 5 of the scope of the patent application, preferably a touch screen and a different editing interface for the manually set display interface and control interface, especially for processing one A working interface for correcting parameters and/or multiple calibration parameters.

When the control mechanism of the yarn transfer device of the textile machine is integrated into the entire mechanical control system, the embodiment of the textile machine according to claim 6 of the patent application is advantageous.

For textile machines using a plurality of different types of weft yarns, in particular textile machines using different color weft yarns, it is advantageous to provide at least two sets of electrically driven yarns for conveying weft yarns, as described in claim 7 of the scope of the patent application. The line conveyor, and the weft and weft yarns use appropriately designed control devices. In this case, in particular for textile machines using a plurality of different types of weft yarns, it is advantageous, as described in claim 8 of the patent application, that the yarn delivery device for the weft yarns is provided with different correction parameters.

Figure 1 is a side view of a textile machine, in particular a webbing weaving machine, in which the warp yarns 2 are opened by a set of opening means 6 in the weaving area 2 to form a shed 8. The weft yarn 10 is threaded into the opening in each shed 8 by means of a weft insertion device, not further described, and pushed against the edge 12 of the textile by means of a steel sill not further described. The woven textile 14 is pulled out using a set of finished product dispensing devices 16 and rolled into a finished textile roll 18.

The warp yarns are led to the weaving region 2 by one or more warp rolls 20, 20a, 20b, 20c. At least a plurality of warp rolls are each coupled to a separately controllable yarn delivery device 22a, 22b, 22c. The weaving region 2 may also have other one or more weft yarns 10 introduced in sequence, each of which is individually controllably pulled from the yarn rolls 24a, 24b through controllable yarn transport means 26a, 26b.

Figure 2 is a schematic illustration of an example of the above yarn delivery device, which is provided with a motor 28, such as a stepper motor, which drives at least one of the two rollers 32, 34 via a gearbox 30. The rollers, which are about to bypass the yarns 4, 10 to be conveyed.

The textile machine is provided with a control device 36 which operates the components of the textile machine in accordance with the patterning program. The pattern can be produced either in the textile machine itself or can be produced by another separate patterning device 38 and then passed through a disk in the disk reader 42 such as a wire or through a control device 36. Sheet 40. The control unit 36 is provided with a control mechanism such that the input length of the set input warp yarn 4 and/or the weft yarn 10 can conform to the textile finished pattern designed according to the pattern. In addition, the control device 36 is provided with a manually adjustable calibration device for correcting at least one weft yarn 10 and at least one warp yarn at least once when the weft yarn is fed at a time according to the set calibration parameters K _S and/or K _{K .} 4 yarn delivery value. The calibration device will be further described in accordance with FIG.

The calibration mechanism is provided with a set of display screens 44 preferably formed by a set of touch screens, and the display is provided with a row of display and switch assemblies for manual display and operation interfaces. In the first control zone 46, any one of the yarn transporting devices 22a, 22b, 22c, 26a, 26b can be selected by the selection keys 48a, 48b and then displayed in the display area 50. In the second control area 52, the correction parameters K _S and/or K _K can be arbitrarily set to a desired value by the selection keys 54a, 54b, which are displayed in the display area 55. In the third control zone 56, it can be finally reset, and the previously set correction parameters K _S and/or K _{K are} applied to the one latitude or the latitude. The number of the wefts X ₁ to X _n can be adjusted by the selection keys 58a, 58b, and the selected values are displayed on the display areas 60a, 60b. The adjustment button X is used to change the display area and is used to cancel the adjustment in general, and the control device operates the assembly completely in accordance with the pattern. In the example shown, the yarn delivery device 26a is adjusted to have a correction parameter of K _S = 102%, which means that the control mechanism is increased by two percentage points from the original 100% according to the respective general yarn feed length given in the pattern. This value applies to the weft between X ₁ and X ₂ or X ₁ to X ₂ .

With this type of correction device, not only the number of yarns of the general weft yarn can be corrected, but also the number of yarns fed by one or more warp yarns and/or the speed of the finished product feeding device can be corrected with the correction parameter K _W . The correction parameters K _S , K _W , K _K can be set to be the same on different components, but it is most advantageous to set them as different systems. In particular, the present embodiment illustrated, the weft thread transport device for the yarn 26a, 26b, when the conveying different kind of weft yarn through the weft transmission means 26a and 26b, may be provided different correction parameters K _S. Basically, a similar situation exists for the correction parameter K _K on the yarn transporting means 22a, 22b, 22c for transporting the warp yarns.
