Definitions

  • the invention relates to a method for commissioning a warp knitting machine that has at least one bar having first needles facing a support second needles by a positioning drive in the offset direction is displaceable, the one rotation motor and a transmission device, wherein the one Barre moved to a first position in which the first needles in needle lanes between the second needles and stores this first position.
  • the invention is based on the object to simple Way conditions for trouble-free operation to be able to create.
  • This object is achieved in a method of the aforementioned Kind solved by using the barre with help of the positioning drive by a predetermined travel Relocated to a second position, checked if the first needles each in a predetermined area a needle lane between second needles, and, if not, with the help of Positioning drive performs a correction movement, until the first needles in the predetermined area are, from the correction movement, a correction quantity calculated and this correction size for future use stored by the positioning drive.
  • This procedure uses a start-up phase, at least one to the position drive To give parameters with which he corrects himself can.
  • the bar is first displaced by a predetermined amount Offset path to a second position.
  • This second position should theoretically be the first needles swing freely between the second needles can. This movement does not necessarily have to be exact Center between two second needles. on the other hand should be the approach of the first needles to the second needles also do not be too tight to make a collision reliable between first and second needles to be able to exclude. So you will allow a range for example, ⁇ 25% of the distance between two second needles around the middle between two second ones Needles is. If now the first needles outside this permissible range are then repositioned them.
  • This positioning can be the simplest Case under visual control, i.
  • the mechanic checks with his eye whether the first needles after the correction movement approximately in the middle between the second needles are standing. If this is the case, then is also an information available to how much the offset path is to be increased or decreased, so that the desired second position is achieved. In order to Do not do this check for all possible ones second position of the barre, you can now from the result of the correction movement, a correction quantity calculate. This correction size can then be used for others Offset movements are used accordingly.
  • the positioning drive in Drive "inching mode". Every time you type, so everyone Pressing a switch button, the positioning drive actuates and moves the barre by a predetermined small stretch increment in a predetermined Direction.
  • the resolution of the correction movement in small distance or distance increments has the advantage that you basically count only the number of increments must to the information about the correction movement to win.
  • the positioning drive used "knows" the positioning drive not only where the barre is opposite the carrier. He also knows what corrective action the barre has performed to the correct or corrected take second position. There are therefore no additional Transducers required in the Commissioning phase to provide the necessary information. Rather, you can anyway in the positioning drive existing information sources for the situation and / or use movement.
  • the individual steps have a size in the Range from 0.005 to 0.02 mm.
  • the individual steps So they have a size in the range of 1/100 mm. This is on the one hand a resolution that is fine enough to the first needles with sufficient accuracy approximately in the middle to position between the second needles.
  • the single steps are big enough to handle the Correction movement also with the necessary speed to carry out.
  • the barre at least once positioned at a second position, the one Distance from the first position, which is the maximum Offset path of the bar corresponds. If the error, the itself through the transmission between the engine and the Barre results, is linear, then one such Check out for all possible intermediate positions to form a corresponding correction variable.
  • the bar is between two End positions positioned at several intermediate positions and for each intermediate position, a correction quantity calculated. With this procedure one goes away from that the error in the transmission is not mandatory represents a linear size. If you have several intermediate positions forms the correction quantity, then can you divide the maximum offset path into several sections and correct each section separately.
  • the correction quantity is calculated during the Change from one correction mode to another Operating mode and saves it. This allows a particularly simple training of the operating program for the warp knitting machine. If you go to another mode changes, then the machine "knows" that the Previously used correction movement is sufficient to the first needles right opposite the second needles too position. The correction phase for the current one second position is completed. You need no additional controls to the education the correction size and the storage effect.
  • one defines a maximum size of the correction movement and generates an error signal when Correct the position of the barre in the second position this size is exceeded. You hold on to this Detach the fitter from doing so by making a wrong correction the positioning drive to an incorrect position convey.
  • Such a determination can for example, in an interpolation.
  • the saved Correction variables can be found, for example, in stored in a table.
  • the guide 6 extends in essentially over the working width of the warp knitting machine.
  • the bar 14 is driven by a positioning drive 7, having a rotary motor 8.
  • the rotary engine 8 is coupled to a transmission 9, the for example, a reduction ratio of 1:10 or 1:20.
  • a disc 10 is fixed, on the circumference 11th a tape 12 is wound with a maximum of one turn.
  • the band 12 is connected via a coupling 13 with the wire trained Barre 14, which in turn is in the Guide 6 is stored.
  • the Restoring device 15 has for this purpose a pneumatic Cylinder 16, in which a not shown Piston is arranged, with a constant Pressure is applied.
  • a Wire rope 17 attached, via a guide roller 18th guided and connected to the Barre 14. If the Force of the positioning drive 7 is less than the Force exerted by the cylinder 16 on the wire 17 is, then the Barre 14 in the offset direction moved to the right, based on the representation of Fig. 1.
  • the reduction ratio of the transmission 9 is known. Also known is the radius of the disc 10. Accordingly, every angle increment is the motor 8 covers, a certain distance assigned, which traverses the bar 14 in the offset direction 3. If So you know that you have the first needles 2, so the Barre 14 to an offset movement "X" (see Fig. 2) would like to shift, then the positioning drive 7 so be actuated that the disc 10 to one of the Offset motion X corresponding angular increment rotates.
  • the positioning drive 7 has for this purpose a controller 19 on, which not only drives the engine 8, but also an information about the angular position of the rotor of Motors 8 gets fed back.
  • a first needle 2 is in a first position To recognize P1.
  • P1 is the first needle 2 is capable of passing through a needle lane 20 to be moved between two second needles 4 is located.
  • Under “Nadelgasse” 20 should not only exactly the area between two second needles 4 be understood, but also an area before and behind the second needles 4.
  • the installer who carries out the commissioning positioned So the first needles 2, first of all, once in the middle between two second needles 4 in a needle lane 20.
  • the position P1 thus set becomes the first one Position in the controller 19 or a parent, main controller connected to the controller 19 (not shown in detail) stored.
  • the first needle 2 by a desired offset movement X offset in offset 3. She then stands in one second position P2.
  • She stands in one second position P2.
  • the first needle 2 in the position P2 is too close to a second needle 4. This could be in operation to collision between the first needles 2 and the second needles 4 lead.
  • the offset motion X may be in a normal mode of operation, for example, an operating mode "automatic” be carried out, so as the Barre 14 in the Operation is moved. This gives largely realistic Replicas of an operating situation.
  • the fitter determines that the position reached P2 is not acceptable, then he switches to one Correction mode.
  • the correction mode is the positioning drive 7 is operated in "inching mode". at every tap on a designated and not Actuator button shown in detail, the Barre 14th moved by a small path increment, for example 1/100 mm.
  • the fitter triggers by "tip movements” so so many offsets of Barre 14 by 1/100 mm out until the first needle 2 again in the middle in a Nadelgasse 20 between second needles 4 stands. It lays down the first needle 2, for example, a distance dX back, so that they are then in a corrected position P2 'is located.
  • the route X can have a length of 150 to 250 mm. Of course, such an offset does not always have to be exploited.
  • the maximum offset corresponds doing something less than the circumference of the disc 10th
  • the size dX must be the right one Signs have been previously determined, i. for investigation the corrected position Y 'becomes one on the Correction value based correction value depending on of the resulting error either added to it or deducted.
