Definitions

  • the present invention relates to an operating method for a weaving machine, iterating a weft through one open compartment formed by warp threads is guided, the Weft thread attached to the edge of the goods by means of a reed the compartment is closed and opened again, so that the warp threads reach around the weft thread and the reed is moved away from the edge of the goods.
  • the object of the present invention is a Generic operating method to create the Avoid weaving errors (weft streaking) of the prior art become.
  • the weft is independent chipped correctly from the position of the goods edge.
  • the weft thread can be knocked against the edge of the goods in a controlled manner become. However, it is preferably torque or force controlled posted on the edge of the goods.
  • the target torque or the target force is time-dependent, in particular a control for the reed from the outside the process is particularly flexible.
  • the target torque can - depending on Accuracy requirements - independent of swivel angle or be swivel angle corrected.
  • the compartment can be removed after the reed has moved away from the edge of the goods or together with the removal of the reed from the edge of the goods closed or opened again.
  • warp threads 1 - in their entirety also called a chain - from a warp beam 2 to led a match tree 3. From there they are guided by thread guides 4, 5 further to a goods take-off roller 6 and one List of goods 7 led.
  • the warp threads 1 are alternating assigned to the thread guide 4 and the thread guide 5. Between the thread guides 4, 5 and the take-off roller 6 is located there is an edge of goods 8, i.e. the border between already woven material (fabric) and the still non-woven warp threads 1.
  • the weaving machine is controlled by control device 9.
  • the 1 is designed as a microprocessor 9.
  • the control device 9 is therefore programmable. Their function is determined by a computer program 10 with which the control device 9 is programmed. Corresponding the computer program 10 operates the loom, controlled by the control device 9, iteratively following, in Connection with FIG 3 process described in more detail.
  • an upper compartment 11 and a Sub-compartment 12 opened.
  • the thread guide 4 upwards, the thread guide 5 deflected downwards.
  • the warp threads 1 guided by the thread guide 4 then form the so-called upper compartment 11, which are guided by the thread guide 5 Warp threads 1 the so-called lower compartment 12.
  • the upper compartment 11 and the sub-compartment 12 together form the so-called compartment.
  • a weft thread 13 is then passed through the step 22 Compartment guided and in a step 23 by means of a reed 14 struck on the goods edge 8.
  • the striking takes place with a target torque M * that the control device 9 from the outside is specified.
  • the target torque M * can in particular as indicated by the addition "t", be time-dependent. In extreme cases, one can even have 13 for each weft thread own target torque M * can be specified.
  • the control device 9 outputs the target torque M * supplied to it proportionately to two controllers 15, 15 '.
  • the reed drives 16, 16 ' By means of the reed drives 16, 16 ' so the reed 14 moves in a torque-controlled manner so that it Weft thread 13 with the nominal torque M * strikes the fabric edge 8.
  • the reed 14 can also be by means of a single reed drive can be moved.
  • the error message F can alternatively be visual perceptible, an acoustically perceptible or a data technology Error message. The process of recognizing a Thread break will be described later in connection with FIG 4 become.
  • Step 27 determines a correction value k for a material deduction.
  • the correction value k is based on a target position P * for the reed 14 and the actual positions saved in step 24 P, P 'determined.
  • the target position P * is constant, as can be seen from the lack of any addition.
  • the target position P * is indicated by dashed lines in FIG.
  • Based the correction value k becomes a speed in a step 28 v determined for a material deduction. by virtue of des - of course within a tolerance range - variable goods edge 8 are the actual positions P, P 'as Correction factor can be used to regulate the deduction of goods.
  • the determined speed v is fed to a controller 18, then a material take-off element 7, here the goods tree 7, correspondingly by means of an associated trigger drive 19 controls.
  • the merchandise tree 7 could also another material take-off element 6, e.g. the take-off roller 6, can be controlled.
  • steps 29 and 30 the reed 14 is removed from the edge of the goods 8 moved away and the compartment closed.
  • step 21 The system then jumps to step 21 again.
  • the iteration also runs through the subject again open, but thread guides 4, 5 swap - at least partially - their positions. Wrap around the warp threads 1 therefore - at least in part - the weft thread 13.
  • the compartment is closed after the reed 14 has moved away from the goods edge 8 and opened again. But it is also possible that Closing the compartment before moving the reed 14 away from the goods edge 8 to execute. It is even possible to close the compartment and to open it again, that is, to reach around the weft thread 13 through the warp threads 1 before the reed 14 from Edge of goods 8 is moved away.
  • a deviation ⁇ is determined.
  • the index n in step 31 (and also in step 33) refers to the current iteration, the index n-1 on the previous iteration.
  • the deviation ⁇ is a measure of how much the sum of the actual positions, d. H. P (n) + P '(n), from an expected actual position, d. H. P (n-1) + P '(n-1) + 2k (n-1), deviates.
  • Then in one Step 32 checks whether the amount of the deviation ⁇ is one Threshold value exceeds max1. If this is the case, be on Thread break detected and continued with step 26. It takes place on the basis of successive actual positions P, P 'a breakage detection for the weft thread 13.
  • step 33 determines another way.
  • the deviation ⁇ gives the displacement between the reed drives 16, 16 'again.
  • the amount of this Deviation ⁇ exceeds a further threshold value max2. If this is the case, it is recognized again for weft breakage and proceed to step 26. Also based on the Actual positions P, P 'of the reed drives 16, 16' as such can thus a breakage detection for the weft thread 13 is carried out become.
  • FIG. 5 shows a variant of FIG. 2.
  • the reed 14 is namely about an axis 20 pivoted.
  • the embodiment according to FIG the reed 14 moves linearly.
  • the embodiments correspond according to FIG 2 and 5 with each other.
  • the operating method according to the invention is in particular when starting the loom from standstill - regardless of whether starting after a weft break or after a normal standstill - immediately a good one Web result achievable without weft streaking.
  • the quality the web result is essentially independent the production speed and the actual positions P, P '. Therefore, especially after a thread break, there is no weft search more needed.
  • the productivity of the weaving machine can be increased.
