Definitions

  • the present invention relates to an avoidance method weaving defects in the weaving of a weaving machine according to the preamble of claim 1, and a weaving machine to carry out this method according to the preamble of claim 4.
  • DE-C2-41 37 681 describes a method for prevention a weft in a weaving machine in which the Woven goods and thus the goods edge at a standstill or crawl or positioning of the loom is shifted to then avoid weft strips when restarting the weaving machine.
  • the present invention is therefore based on the object the method described at the beginning and the weaving machine to improve this method so that they safely avoid the disadvantages described and with easier and safer handling any web errors in the Tissue formation can be excluded.
  • Another object of the invention is to operate the Make the loom as quickly as possible, so that on the positioning the goods edge at a restart or the like can be dispensed with.
  • Control device takes place, this procedure is required also with speed variations within the weaving process, e.g. due to different weft yarns (e.g. yarn fine and material) no manual corrections or Re-adjustment of the goods edge.
  • the fabric edge control continuously adapts the fabric edge to the current weaving speed. Even if, for example, after the start of the weaving machine, the first weft takes place at approx. 250 min -1 , the second then at 470 min -1 and the final speed of 500 min -1 is reached only after the third weft take, there are no starting points (open Put).
  • All auxiliary drives work on the principle of the "electric wave", i.e. the absolute synchronicity of all auxiliary drives
  • the main shaft of the weaving machine is done by electronic Control.
  • the motors of the turn the Warp beams only with the gear factor calculated last Main shaft encoder. After the settling time of the dancer systems of the warp beams, becomes the position controller of the dancer systems switched on. If the position controller detects an increasing or decreasing Thread tension, so the corresponding warp beam accelerated positively or negatively via the control system, continues the gear factor becomes proportional at the same time re-adjusted to the warp beam diameter.
  • This new procedure for drive and Control can be used especially in weaving machines for flat fabrics, Weaving machines based on the push-nub-pile principle work (e.g. for terry fabrics) and with double pile weaving machines (e.g. for velvet and plush fabrics) become.
  • Fig. 1 shows a flat weaving machine 20 with a main motor 1, an adjustable auxiliary drive 2 for the goods tree, an adjustable auxiliary drive 3 for the warp beam and one Position controller 4 for determining the warp thread tension.
  • the auxiliary drives 2 and 3 work on the principle of electric shaft, driven by the main motor 1 Main shaft of the weaving machine 20, these auxiliary drives 2 and 3 continuously by the computer (not shown) in the weaving machine control are influenced or regulated.
  • FIG. 2 shows a weaving machine 30 which works according to the push-nub-pile principle works (e.g. a terry loom).
  • a weaving machine 30 which works according to the push-nub-pile principle works (e.g. a terry loom).
  • the drives described in the flat weaving machine 20 1, 2 and 3 and position controller 4 for the basic chain come with these types of weaving machines 30 the auxiliary drive 5 of the warp beam for the pile chain 5 and the associated one Position controller 6 added.
  • This auxiliary drive 5 is like the other auxiliary drives 2 and 3 constantly by the Computer in the weaving machine control influenced or regulated.
  • the drawing Fig. 3 shows a double pile loom 40 with Dobby and a main motor 1, an auxiliary drive 2 for the goods tree, one or more auxiliary drives for one or more pole pulling booms 7, 8 and 9, each pole pulling boom controlled by its own adjustable auxiliary drive becomes.
  • a clutch it is also common to have several pole trees switched on and off by a clutch, with two auxiliary drives for the basic warp beam regulators 10 and 11 and the associated position controllers 12 and 13 and one or several auxiliary drives for the pile chains, for example 14, 15 and 16 with the associated position controllers 17, 18 and 19th
  • the auxiliary drives for the Position controller and the pole warp beams, with the corresponding Position controllers one or more may come for this Auxiliary drives for mirror chains with the corresponding position controllers added.
  • All of these auxiliary drives are in constant use according to this invention influenced by the computer in the weaving machine control or regulated.
  • the factors k for weaving machines according to the invention were determined by experiments. For a wide variety of weaving machine types a series of tests is required, through which an error rate of approx. ⁇ 10 ° at a certain speed the value k is determined and recorded in tabular form becomes. The error rate can be customized through manual Intervention in the weaving machine control balanced become.
  • the weaving machine is now operated at a different speed, for example at 20 min -1 (creeper speed)
  • the motors of the auxiliary drives therefore only need to be adjusted by 3,200 angular increments.
