Definitions

  • the invention relates to a method for adjusting a match tree and / or a warp guard device of a weaving machine, its match tree and / or Warp guard device on the machine frame adjustable and supported by assigned Actuating means with at least one actuating function from an actual position to a given one
  • the target position can be transferred and ascertained in this.
  • the warp threads of the warp must be for one Weft entry from the so-called binding point up to the reed in a top and a Subdivide. This happens with shafts in dobby machines and with Harness cords on jacquard machines.
  • the resulting angles between the warp threads delimiting the shed are directly dependent on the position of the match tree and the stroke of the stems (harnesses) dependent. These angles of the shed are important for weaving and different for different tissues. That usually means that with one Change of the fabric to be manufactured (change of article) the position of the match tree must be changed and readjusted. The same often applies to the so-called Warp guard device whose task is to move the warp to break the warp thread monitor and stop the weaving machine if a warp thread break occurs.
  • DE 195 98 121 C1 describes an uncontrolled tensioning unit for the warp known a weaving machine that basically shows how a coating roller (match tree) containing tensioning unit on the weaving machine frame in horizontal and is adjustable adjustable vertical direction.
  • the clamping unit is on two sides on two sled-like Components stored, which are guided in a longitudinally displaceable manner on two guide parts, which in turn can be pivoted about a common horizontal axis on the side cheeks of the weaving machine frame are stored. Interacting with corresponding elongated holes Clamping screws allow the clamping unit and thus the coating roller in the to position the ideal target position for the tissue to be produced.
  • the clamping unit is adjusted by hand.
  • the loom of the loom is rectangular on each side of the machine by means of two slide-like bearing parts which can be moved relative to one another are mounted on the machine frame, clamping screws reaching through elongated holes allow it in the horizontal and in the vertical direction adjustable match tree in its respective target position convict and determine in this.
  • the actuation of the clamping screws and the Adjustment of the match tree from the actual position to the target position is done by Hand.
  • the slide-like bearing parts are non-contact on each side of the machine, optical sensors assigned to the horizontal and vertical position of the match tree determine and deliver appropriate data to a control unit where this data is stored and displayed on a screen.
  • the operator can thus follow the setting process on the screen, reaching a specified target setting is indicated by light signals.
  • the setting of the two-matched tree still remains time-consuming because on Each machine side loosened a large number of clamping screws by hand and after also manual movement of the match tree into the respective target position by hand must be tightened again. The same applies, by the way, to the Warp guard device, if there is one.
  • the object of the invention is therefore to show a way that a fast and precise adjustment of the match tree and / or the warp guard device at one Weaving machine allowed.
  • the method according to the invention has the features of claims 1 and 13 while a to carry out this method certain device according to the invention is the subject of claim 14.
  • match tree is not limited to a single one Coater roller limited, but it also includes those embodiments in which the function of the match tree for tensioning and redirecting the warp to several Rolls is divided, which may be combined into a clamping unit, such as this is illustrated, for example, in the aforementioned DE 195 38 121 C1.
  • the adjusting means is at least one controllable, driven actuating device assigned, which allows the necessary To generate positioning movements, for example in the horizontal and / or vertical direction.
  • the respective actuating function of the actuating means i.e. whether they are used to generate adjustment movements in, for example, horizontal or vertical Serve direction, recognized.
  • the current position of the match tree and / or the warp guard device This actual position is automatically included a predetermined target position for the respective actuating function compared. For this Comparison becomes one for moving the match tree and / or the warp guard device generated in the desired position control signal that supplied to the actuator becomes.
  • the adjusting device then actuates the adjusting means for the adjustment required dimensions. In this way, the match tree and / or the warp guard device automatically positioned exactly in the respective target position.
  • the setting of the Matchsticks can be used together or separately from that of the warp guard device if there is one on the weaving machine.
  • a movable one is usually used to operate the individual control functions Actuating device used, which is detachably coupled with the individual adjusting means and after Completion of the setting process is uncoupled from the actuating means.
  • the arrangement can be such that the Actuating device is designed as a movable actuating unit containing the drive, which can be detachably coupled to the actuating means of the respective actuating function.
  • the Actuators can be assigned to the individual actuating functions, movably mounted Bearing parts, for example, have slides, each with a self-locking gear are adjustable and contain a threaded spindle as actuating means.
  • the drive unit connected to the weaving machine control is secured against rotation one after the other on the threaded spindles assigned to the individual actuating functions placed. It recognizes the location and the function of the Spindles.
  • a non-contact measuring system on the actuator such as an ultrasonic sensor or a laser measuring device, determines the existing distance setting of the assigned Bearing part or slide based on a fixed reflector or reflection plane and transmits the corresponding data to the weaving machine control. in the Comparison with those specified by the operator or via a data network transmitted setting values, the drive of the actuating device is automatically corresponding move until the specified setpoint is reached.
  • the vertical adjustment range for the match tree setting leaves alone an adjustment of approx. 200 mm. That is why the warp guard device is also necessary to be able to proceed accordingly.
  • the self-locking gears and their actuating means designed as threaded spindles This results in a total of four movably mounted machines Bearing parts (slide) with associated threaded spindles. Serve two threaded spindles for vertical and horizontal adjustment of the match tree; the remaining two Threaded spindles allow vertical and horizontal adjustment of the warp guard device.

You can also click on the way according to the invention, the settings of the match tree and / or the warp guard device during the weaving process, i.e. during production for optimization the setting can be easily changed.
  • Such a change in the setting of the match tree can also be used according to the invention to keep the geometry of the so-called rear pocket lying between the heald frames and the match tree constant, regardless of a changing winding diameter of the warp beam during weaving.
  • the position of the match tree changes with a decreasing warp beam winding diameter and thus the geometry of the rear compartment set to the relevant winding diameter.
  • an optimal match position achieved by means of the actuating units of the match tree is stored as a target value in the control unit, and a change in the position of the match tree based on the decreasing warp beam winding diameter is measured continuously as actual values by means known per se to detect, to supply these actual values to the control unit in a signal-transmitting manner and to maintain the desired setting of the match tree in the course of a continuous comparison of the desired and actual values by adjusting the position by running or at intervals in time.

In the event of warp thread breakage she turns off the loom. As the warp guard device 17 for its proper Function must be in a predetermined assignment to the warp threads, if the match tree 3 is adjusted, the warp guard device is generally also required 17 to adjust accordingly.
