Definitions

  • the invention relates to an arrangement and a method for optimizing a weaving process. More particular, the invention relates to an arrangement and a method for avoiding weaving errors due to an incorrect threading of a weft thread preparation device of a weaving machine.
  • a fabric consists of warp threads and weft threads.
  • the weft threads are inserted in between warp threads during an insertion cycle of the weaving process.
  • Weft threads are fed to the weaving machine and are wound on bobbins, which are typically placed on bobbin racks or bobbin creels arranged on one side of the weaving machine, generally on the left side.
  • a weaving machine Before starting to weave a new fabric style, a weaving machine has to be equipped with raw materials. Starting from the rack, the weft thread of each bobbin is manually threaded to a prewinder that prepares the weft thread for the weft insertion.
  • a weaving machine can have one prewinder or up to twelve prewinders.
  • one prewinder contains weft thread coming from one bobbin.
  • two or more weft threads coming from an associated bobbin can be wound simultaneously to a common prewinder.
  • two or more weft threads coming from an associated prewinder can be inserted simultaneously in a weaving shed, for example by means of a gripper or a main nozzle.
  • a leading end of a second bobbin is tied to the trailing end of a first bobbin, to enable longer machine running cycles without interventions to supply new bobbins.
  • a weaving machine is equipped with twelve prewinders and with one or more racks that form together twelve platforms for bobbins, wherein each platform comprises one or two pins, on which a bobbin is placed.
  • weft insertion channels are used to determine the sequence by which the different weft threads are inserted. This sequence is often referred to as a "color pattern".
  • One or more element(s) is/are assigned to each virtual channel, which is/are driven by the control device to withdraw a weft thread from a bobbin and/or to insert a weft thread threaded or otherwise coupled to said element.
  • said elements assigned to virtual channels are referred to as weft insertion channel elements.
  • weft threads are manually threaded to prewinders of a weft thread preparation device and are threaded from the prewinders through weft thread brakes to one weft thread presenter.
  • the weft thread presenters and the prewinders are driven by the control device in order to wind the weft thread to the prewinder and thereby to draw off weft thread from the bobbin, and/or to present a particular weft thread to a bringer gripper for an insertion of said weft thread.
  • the weft insertion channel elements comprise the prewinders and the weft thread presenters.
  • weft threads from prewinders are fed to one or a set of main nozzles, wherein the main nozzles are driven by the control device in order to select the weft thread to be inserted during a weaving machine cycle.
  • the weft insertion channel elements comprise the prewinders and the main nozzles.
  • weft thread threaded to the weft insertion channel element(s) and, thus, added to a weft insertion channel is known.
  • threaded to a weft insertion channel element means that weft thread is coupled along its movement path in a certain way to the weft insertion channel element.
  • the weaving machine can determine, for each kind of weft thread, the weft insertion channel corresponding to that kind of weft thread, and can convert the entered weft insertion pattern as a function of the kind of the weft thread to a weft insertion pattern as a function of the weft insertion channels.
  • the object of the present invention to provide an arrangement and a method for avoiding weaving errors due to an incorrect threading of a weft thread preparation device of a weaving machine.
  • an arrangement for optimizing a weaving process comprising a control device, a number of weft insertion channel elements, each weft insertion channel element being allocated in the control device to one weft insertion channel, and a bobbin rack with a number of platforms each having a weft thread property identifying sensor, wherein weft threads of bobbins placed on at least some of the platforms are fed to at least some of the weft insertion channel elements, wherein at least at some of the platforms, and preferably on all platforms, a weft thread movement detector arranged for detecting a weft thread movement is provided, and wherein the control device is arranged
  • Platforms may be provided with one pin or more than one pin, in particular two pins.
  • a weft thread from a bobbin placed on any pin of any platform could be manually threaded or otherwise coupled to any of a number of prewinders and from the prewinder to any of the number of further weft insertion channel elements, for example to a weft thread presenter or a main nozzle.
  • weft threads fed from at least some of the bobbins placed on the platform can be manually threaded or otherwise coupled to at least two different prewinders without difficulty. This may result in weaving errors.
  • the control device assumes that a first weft thread of a first type has been threaded to a first prewinder and a second weft thread of a second type has been threaded to a second prewinder, however, when setting up the weaving machine the first weft thread of a first type is threaded to the second prewinder and a second weft thread of a second type is threaded to the first prewinder, this will result in a weaving error, which cannot be detected with prior art control devices.
  • the platforms of the bobbins from which weft threads are drawn off are determined by means of the control device and properties of the weft thread arranged on the determined platform are identified.
  • Suitable weft thread movement detectors may be chosen by the person skilled in the art.

  • control device is arranged for adjusting an allocation of weft insertion channel elements to a weft insertion channel based on an identified threading of a weft thread. For example, if a first prewinder has been assumed to insert a weft thread coming from a first platform, however, the weft thread has been threaded to a second prewinder, the second prewinder will be allocated to the weft insertion channel instead of the first prewinder.
  • the control device is arranged for adjusting a weaving sequence of weft thread of a weft insertion channel for weaving a particular weaving pattern based on identified weft thread properties.
  • the control device has identified that a red weft thread is threaded to the weft insertion channel element allocated to a first weft insertion channel, however for weaving a particular weaving pattern a green weft thread is required, and a green weft thread is threaded to the weft insertion channel element allocated to a second weft insertion channel, however for weaving a particular weaving pattern a red weft thread is required, in the weaving sequence the first weft insertion channel and the second weft insertion channel are exchanged.

  • the reader element in one embodiment is an optical reader element, for example a barcode reader element or a QR code reader element.
  • radio frequency technology is applied, and in particular an RFID reader element is provided.
  • sensors detecting the color, the hairiness or other weft thread properties may be provided. It is well known to provide more than one bobbin on a common platform, wherein a trailing end of a first bobbin is attached to the leading end of a second bobbin.

  • a weft thread coming from a prewinder may be threaded to different weft presenters without difficulty.
  • it is determined to which prewinder as well as to which weft presenter a particular weft thread is threaded. Hence, weaving errors can be avoided.
  • a method for optimizing a weaving process in a weaving machine comprising a control device, a number of weft insertion channel elements, each weft insertion channel element being allocated in the control device to one weft insertion channel, and a bobbin rack with a number of platforms each having a weft thread property identifying sensor, wherein a bobbin is placed on any one of the pins of any one of the platforms of the bobbin rack and the weft thread of said bobbin is fed to one of the number of weft insertion channel elements.
