Definitions

  • the invention relates to a textile machine with a drafting system.
  • Such machines are used to lengthen strand-like fiber material and thus make it finer.
  • spinning preparation machines such as draw frames, band winders and combers
  • slivers are laid side by side and stretched, so that a single sliver with predetermined properties is created that is usually deposited in a can.
  • a flyer stretched and, if necessary, combed sliver is spun onto a roving.
  • drafting systems that lengthen the incoming fiber material.
  • Spinning machines also have drafting systems to lengthen roving, which is ultimately spun into the yarn.
  • the above-mentioned spinning preparation machines operate essentially independently within the production chain mentioned.
  • the sliver to be manufactured they can be tuned to downstream textile machines such as belt winders, combers, flyers and spinning machines, but they are coordinated with the spinning preparation machines themselves.
  • these machines are related to the production chain from the fiber bale to the Sliver that is spun is set up separately from each other. Apart from that, sliver breakage very often occurs. Although this is automatically eliminated, in particular in spinning machines, the frequency of such breaks may be interesting in order to be able to draw conclusions about the quality of the fiber material to be drawn, the drafting device settings and the like.
  • a textile machine with a drafting system has an operating section.
  • the operating section is designed to stretch fiber material, for example in the form of fiber tapes, and to output it to a subsequent processing section like a can tray.
  • the textile machine has a display section.
  • the display section has a plurality of lighting elements.
  • the textile machine comprises or is coupled to a control.
  • the controller is set up to control the operating section according to predetermined operating parameters specified for the operation of the textile machine and to control the lighting elements according to a predetermined lighting scenario.
  • the lighting elements are controlled in such a way that the lighting elements display:
  • a position of a detected fiber material break a frequency of detected fiber material breaks on the creel, in the fiber material store or at another location, based on a reference size and / or
  • Luminous elements are not, for example, lighting units on a screen, such as LCD cells with background lighting, which together form an image. Rather, the arrangement of lighting elements may have a certain geometric or figurative shape (like that of an arrow), but without a certain meaning (such as for a letter, for example).
  • the lighting elements represent the information in a certain way coded. In the case of the frequency of fiber material breaks, for example, a more lightly controlled lighting element can signal a greater frequency.
  • the controller can also be set up to image the filling status of a can placed on a filling location of the can depositing device.
  • the aforementioned lighting elements are preferably arranged in a row. This is a particularly simple form that can be implemented particularly inexpensively.
  • the lighting elements are preferably divided into adjoining display areas. This means that each display area relates to a different section of the textile machine and / or to another information that is displayed. This enables several pieces of information to be displayed at the same time.
  • two immediately adjacent display areas are optically spaced from one another.
  • This enables the display areas to be recorded optically distinguishable from one another.
  • the spacing can be realized by in each case at least one lighting element between the two display areas
  • the controller is set up to operate the at least one lighting element in accordance with a predetermined lighting scenario that optically separates the delimitation of two immediately adjacent display areas.
  • Each display area is preferably assigned to a respective one of the fiber material stores in the case of the filling states being mapped. So that can can be recognized in relation to which can position on the creel the corresponding can is filled and how far to enable a person to consider a possible can change.
  • each display area can be assigned to a respective section of the textile machine in the event of contamination being displayed on or in the textile machine or in the drafting system. In the case of a stretch, the sections can be the lead-in area, the measuring area, the drafting system and the can depositing device. If deviations are displayed in the fiber material, each display area can be assigned to a respective deviation. This can be, for example, the thickness of the fiber material and its color deviations.
  • each display area can be assigned to different deviation directions. If the operating state of the sensor system of the textile machine is displayed, each display area can be assigned to a respective section of the sensor system, for example the fiber sliver inlets on a creel. If the number of cans located in a can depositing device downstream of the drafting device is displayed, each display area can be assigned to a respective can parking space. In the case of displaying the position of a break of the fiber ribbon as a special form of a fiber material, each display area can be assigned to a respective fiber ribbon in relation to an associated can parking space on a gate upstream of the textile machine, so that it is clearly recognizable in relation to which can the Sliver breakage has occurred.
  • the display areas can be assigned to a respective area between drafting system and fiber material store or in the textile machine, so that also troubleshooting is enormously simplified here.
  • the controller is preferably set up to control the lighting elements when changing the cans so that the respective can optically “moves” from one display area to the next. The can movements are thus simulated in a visually simulated manner.
