Definitions

  • the invention relates to a method for avoiding Tissue marks in a weaving machine with a Reeds that are set to a target stroke distance is.
  • EP-A-350 446 describes a method for operating a Terrycloth loom known, in which the sley is driven by the main drive of the weaving machine and is operated by a separate drive that through a sequence of freely programmable pulses is controlled individually. That’s why well-known terry rhythms with different pile heights executable.
  • the invention has for its object a method to avoid tempering spots in the tissue in such To create loom.
  • the procedure in question is used here to avoid weaving errors, taking the course of the procedure depends on whether a weft fault, e.g. a Weft break, partial weft, etc. or another Stop event, e.g. a warp thread break, a shutdown the weaving machine, etc.
  • a weft fault e.g. a Weft break, partial weft, etc.
  • Stop event e.g. a warp thread break, a shutdown the weaving machine, etc.
  • Fig. 1 shows a terry loom.
  • the basic chain 7 runs over a Spanning tree 4 to the shed 9.
  • the fabric 10 is over a Breast boom 6 and a take-off roller on a goods boom 3 deducted.
  • the pile chain 8 is pulled over by the pile warp beam 2 a pendulum roller 5 passed to the shed 9.
  • a reed 12 the sley 11 is from a Loom main drive shaft 13 via a Shutter control device 14 driven.
  • a Servo motor 15 provided with the The shop control device is drive-connected to the Set stop distances.
  • the servo motor 15 is included a control device 16 electrically connected to the Servo motor 15 in accordance with a control program head for.
  • the corresponding monitoring devices apply an error signal to the control device 16 which, in a control step by the servo motor 15, sets the shutter control device 14 to a suggested distance VD max , VD max compared to VD target or AD target at least by it is so much greater that the reed and any existing partial weft no longer changes the position of the previously correctly inserted weft, ie there is a minimal distance to the previously correctly inserted weft.
  • the main shaft of the weaving machine rotates until a stop position is reached, in which a control step "stop initiation" takes place.
  • the main shaft is rotated in the running direction in order to achieve a predetermined position, for example the end of the trade.
  • a control step "shot search" is initiated which, depending on the specialist position, consists of two independent search processes. After the corresponding search process has been completed, the weaving machine is stopped (FIG. 2).
  • the servo motor allows the shutter control device to reach the suggested distance VD max either directly after the stop event or before the reed makes the full stop again - Position reached, adjusted.
  • the characteristic values are: Target proposal distance, target full stop distance, Shot density, number of proposal shots by Full stop and fabric type saved. Furthermore, in Depending on these parameters, a correction process which of the correction steps are saved specifies. It is noted that further Characteristic values can be taken into account.
  • This correction is done step by step manually adjustable correction steps, which each Assigned stop, and repeated until the target stroke distance for the proposal shot and the Full stop shot is reached.
  • the correction can within one or more shot groups.
  • the machine is usually restarted with a manually triggered start command.
  • a Control step is the weaving machine in a start position brought. This process is independent of whether Terry or smooth fabric is made.
  • the shed control device When the machine is restarted, the shed control device is drive-connected to the main shaft of the machine. In order to put the weaving machine from standstill into the operating state, one or more empty shots can be carried out when the weaving machine starts up, VD max being set while the weaving machine starts up and the number of empty shots being freely selectable.
  • the proposal distance VD 1 is set, which is the sum of the target proposal distance VD target plus / minus a correction value Vk 1 .
  • the first suggestion shot for example in the case of a thin spot in the fabric, is shifted beyond the target suggestion distance, or in the case of a thick spot in the fabric over a distance which is shorter than the target suggestion distance, in the warp direction.
  • the second proposal shot is entered and the proposal distance VD 2 is set, which is the sum of the target stop distance VD target plus / minus a correction value Vk 2 .
  • the second proposal shot is thus also shifted in the warp direction with respect to the target proposal distance VD target .
  • the stroke distance AD 1 is set, which is the sum of the desired full stroke distance AD desired plus / minus a correction value Ak 1 .
  • the further weaving process either takes place without further corrections of the values VD and AD, that is to say the fabric produced subsequently has a weft density and loop height with the specified values, or with further corrections for at least one additional shot group with changed values for VD and AD compared to the previously fired shot group.
  • the correction values can have the same or different values (FIG. 4).
  • the values VD 1 , VD 2 and AD 1 are changed for the next same error event. If a thin or thick spot in the tissue is found, the full stroke distance AD is changed, and in the case of a thin spot the value of AD is increased and in the case of a thick spot the value of AD is decreased. If a discrepancy in the loop height is found, the values VD 1 and VD 2 are changed; if the loop is too high, the values of VD 1 and VD 2 are reduced, and if the loop is too low, the values of VD 1 and VD 2 enlarged.
  • a stop distance AD 1 is set, which is the sum of the desired full stop distance AD target plus / minus a correction value Ak 1 .
  • the weft group is thus shifted accordingly in the warp direction with respect to the target full stop distance AD target . If the correct position of the weft group with respect to the fabric edge is achieved by this correction process, the further weaving process either takes place without further corrections of the values VD and AD, that is to say the fabric produced subsequently has a weft density and loop height with the specified values, or with further corrections for at least one additional shot group with changed values for VD and AD compared to the previously fired shot group.
  • the correction values can have the same or different values (FIG. 4).
  • the target stop distance in Meaning of an extension or shortening to Events, e.g. Thick and / or thin places, too avoid so that tissue, e.g. Terrycloth or Smooth weave, produced with a weft density according to the program becomes.
