  • the invention relates to a warping machine according to the Preamble of claim 1.
  • Such a warping machine is known from DE 91 10 393 U.
  • the Skiving carriage is parallel to the drum axis and across movable for this. Difficulties arise here on because thread feed and measurement are practically the same Place. So you need a deflection roller and has to accept limited space.
  • a method of warping threads on a warping drum a warping machine is from D2-OS 37 02 293 known. With this procedure, a warping becomes dependent of the increasing winding thickness relative to Warping drum moved by warping the first Belt with a specified skewer feed of the winding circumference by a feeler when the warping drum is at a standstill scanned and its adjustment path during a measuring winding phase depending on the number of Revolutions of the warping drum is measured. After that when warping the rest of the first warp and after copying the measuring roll when the subsequent belts are warmed the feed of the warping carriage during warping the rest of the following tapes according to the measured Adjustment path corrected.
  • the disadvantage of the known method is that a step wrap due to the three-part structure of the first warp belt is created.

  • the thread sheet can be deflected without by Schwarzrriet on the reel.
  • a start and a learning phase are planned.
  • the Start phase is initially an initial value for the feed rate depending on the warp parameters, e.g. the total number of threads of the warp width and the Yarn number determined.
  • This preliminary, theoretically determined Feed rate value is at least for the first rotation of the warping drum as a feed speed signal used.
  • the learning phase begins either with the start phase or after the start phase, being continuous in the learning phase the contact thickness of the warping belt is measured without contact is by a coating thickness measuring device at a predetermined, substantially constant distance from the surface of the just wound up Warp is held.
  • the essentially constant Distance from the surface of the thread sheet is required in order to measure the thickness of the coating their optimal measuring distance from the surface of the warp to keep as it is based on an extremely accurate distance measurement arrives. From the signals of the application thickness measuring device the application thickness can be determined and the feed rate depending on the thickness of the job at the earliest from the second turn of the Warping drum can be regulated.
  • the duration of the learning phase is from the stabilization of the feed rate signals specified by the control dependent. This stabilization occurs depending on Yarn quality after a different number of Revolutions, e.g. after about 30 turns. So if the regulation has stabilized to a certain extent, is a predetermined number of last received Feed speed signals used to a for the working phase of the warping process is constant Set feed rate signal. The whole The remaining warping process is carried out with this in the learning phase certain feed rate executed.
  • a laser light distance measuring device as a coating thickness measuring device is used.
  • the non-contact distance measurement with the laser enables a resolution of approx. 30 ⁇ m.
  • the constant Feed speed signal in the working phase the average of a predetermined number of Measuring cycles in the learning phase received feed rate signals is set if one also specified, maximum fluctuation range of the regulated Feed speed signals fallen below in the learning phase becomes.
  • the work phase occurs when the standard deviation, for example the last 10 or 20 feed speed signals, a predetermined maximum Falls below the limit.
  • the constant feed rate signal to the controller at the beginning of the work phase is reported back to the required number of turns to comply with the set on the warping machine Determine warp length and the engine control an exact count signal for the current warping process passed, the adherence to the exact warp length guaranteed. A preset number of turns can be used be corrected if necessary. At the same time, the Control if the capacity is exceeded a warning signal output. If the order amount can be exceeded an automatic shutdown of the warping machine is provided his.
  • the application thickness measuring device is preferred synchronized with the rotation of the warping drums and the Change in the position of the warp belt moves. Doing so the distance measurement preferably to the middle of the Warp.
  • the device according to the invention is characterized by this from that the application thickness measuring device both parallel to the warping drum axis as well as orthogonal to the warping drum axis synchronized with the warping drum rotation and the Change in position of the warping belt is movable, the Order thickness measuring device essentially one constant, predetermined distance from the surface of the warp comply.
  • the cone warping machine 1 has a warping drum 2 a cylindrical part 3 and a cone part 4.
  • the Warping drum 2 is supported in bearings 6 by a base frame 7 worn, the base frame 7 is designed as a carriage and can back and forth on rails 9 by means of the wheels 8 be brought here.
  • a motor 11 with an encoder drives by means of a transmission link 12 and one Pulley 13 on the shaft 5 and thus the warping drum 2, a brake 14 is provided for a brake disc 15 is. With 16 the traction motor is designated.
  • Another Motor 17 drives a threaded lead screw 18 from a support 20 along the warping drum 2 by means of a Spindle nut 19 can be pushed back and forth.
  • the support 20 has a warping slide 21 which Guides along the warping drum 2 by means of the spindle 18 can be pushed back and forth.
  • a further carriage 23 is attached on the warping carriage 21 a further carriage 23 in a height-adjustable manner.
  • the further carriage 23 carries the drive mechanism for the movement of a sliding rivet 25 across Warping drum 2 and for height adjustment further Slide 23 with the other parts attached to it, and an arm 48 which is a coating thickness measuring device 55 orthogonal to the warp axis of the warping drum 2 approximately in the middle of the one to be wound up Sash tape holds.
  • a motor 28 drives by means of the transmission members 29, 30 a shaft 31 from which several drives are derived are.
  • the sliding rivet 25 is located on a cross slide 32.
  • a transmission link leads from the shaft 31 33 to a worm gear 34, which has a threaded spindle 35 drives the carriage 32 in the transverse direction can move to the longitudinal axis of the drum 2.
  • the Sliding rivet 25 sits on a spindle 37 by a own motor 38 which is driven on the carriage 32 is attached. The shift of the reed 25 in The longitudinal direction of the drum 2 is therefore independent of the Displacement across the drum axis.
  • a gear 40 On the shaft 31 is a gear 40, which with another gear 41 meshes, the shaft 42 with a worm drive 43 which connects the spindle 44 drives.
  • the spindle nut 45 is on the support slide 21 attached so that when the spindle is actuated 44 the carriage 23 is moved in height.
  • Fig. 2 shows the winding construction of the first warp a cone part 4 with a cone angle ⁇ to the drum axis of 15 °.
  • the process for warping threads runs automatically than as from the beginning of the warping process without Interrupting the winding process the entire chain is wound up can be, the first coil of Right from the start with an optimal feed rate is wrapped.
