Definitions

  • the invention relates to a method for regulating the thread bandwidth in warping machines with a rotatable warping drum and with a warping reel that is adjustable in width, and a device for carrying out the method.
  • An adjustable Schwarzeaut has become known from EP-A-174 631.
  • the reed is influenced depending on the thread tension, whereby a uniform diameter on the warp beam is aimed for.
  • the actual bandwidth after passing the Schwarzrriete is not taken into account.
  • the contactless bandwidth measurement with the aid of the optical means has the advantage that the thread tape for the width measurement is practically not exposed to any physical disturbances.
  • the width measurement can also be measured directly in front of or on the run-up point of the thread band on the warping drum, so that the regulation achieves an optimal effect.
  • width deviations on the thread band only extend over relatively short band lengths.
  • the width of the thread band can also be measured on a deflection roller arranged between warping reel and warping drum will.
  • the deflection roller can be made of a reflective material, for example, which can facilitate the measurement process.
  • the bandwidth is particularly advantageously measured using a line scan camera.
  • the line scan camera enables high image resolution and therefore precise measurement results.
  • the line scan camera can also be easily installed in various positions and connected to the control computer via fiber optic cable.
  • other optical measurement methods using incident light or transmitted light methods are also conceivable.
  • FIGS. 1 and 2 show a conventional warping system 1, consisting of warping machine 2 and warping gate 3.
  • a large number of bobbins 4 are attached to the warping gate 3, the threads 5 of which each pass through a thread tensioner 6 in order to generate a constant thread tension.
  • the threads 5 are monitored for existence at the thread monitor 7 and then arrive in the area of the warping machine 2 to the cross-hair reed 8, in which each individual thread 5 is brought into a specific sequence.
  • the threads are formed into a thread band in a specific thread density, which is fed in the desired bandwidth 11 via deflection rollers 12 to the warping drum 13.
  • the thread band 10 is wound on the warping drum 10 in a manner known per se in the form of individual bands 14a, 14b, 14c etc. along the cone 15 on the warping drum 13. It is important that the winding structure of the individual tapes 14 always remains the same, so that the lengths of the threads of all individual tapes match. Various means, not described in more detail here, are provided for a constant thread tension for all threads 5 and for keeping the thread tension constant.
  • the desired bandwidth 11 for a thread band 10 can be set on the warping reel 9 with the aid of a spindle 17.
  • This spindle moves the two halves of the Schwarzrriets in opposite directions in a manner known per se.
  • the spindle 17 is actuated via a handwheel 16, as can be seen from FIG. 3a. According to FIGS. 1, 2 and 4, however, the actuation takes place via a servomotor 35, as will be described below.
  • a line camera 25 is attached above the warping reed 9, the optical axis 40 of which is directed onto the thread band 10 immediately before the point of impact 18 on the warping drum 13.
  • Behind the thread band 10 is a reflective streak in the measuring plane fen 26 arranged, which can be illuminated from the camera side with a light source 41.
  • the bandwidth can thus be measured as a shadow cast on the reflective strip 26.
  • a line camera with approximately 4000 pixels is preferably used, so that a resolution of 0.1 mm can be achieved with a bandwidth of 400 mm.
  • the line camera 25 is mounted above the thread band in such a way that the optical axis 40 runs on a plane which is transverse to the thread band and divides the Schwarzrriet as an angle bisector into two halves. Under certain conditions, the line scan camera could of course also be mounted under the thread band. It would also be conceivable that the optical axis 40 is not directed in a straight line, but rather via a deflecting mirror onto the thread band.
  • the entire arrangement consisting of a warping device, line scan camera and deflecting rollers is arranged on a warping carriage 22 for the inclined guidance of the belts 14.
  • This warping carriage can be moved both axially parallel to the warping drum 13 and transversely to this axis by means not shown. The shift takes place automatically during winding.
  • the warping can be adjusted with the line camera for axially parallel displacement relative to the warping drum, but also with a handwheel 36, which is of particular importance for the start of the winding process. With the handwheel 36, a spindle is rotated, which moves the Schwarzrriet 9 via a linkage 37.
  • FIG. 2 shows schematically the operative connection of the line camera 25 and the servomotor 35 with an operating station 27.
  • This consists of an input station 28 and a processor 32, which acts as a comparison device for the Regulation serves.
  • the input station 28 is provided with input keys 29, with numeric pushbuttons 30 and with a display field 31. It also has a calibration station 39.
  • An input line 38 connects the line camera 25 to the operating station 27, and an output line 33 and 34 each connect the operating station 27 to the servomotor 35 or to the warping machine drive (not shown in more detail).
  • FIGS. 3a and 3b A winding process according to the prior art is shown in FIGS. 3a and 3b.
  • a first band 14a is started to be wound onto the warping drum.
  • the first thread 19 of the thread band 10 must lie exactly at the intersection 20 of the cylindrical part 13a with the cone 13b of the warping drum 13.
  • the winding of the first band 14a according to FIG. 3b can begin.
  • a prerequisite for a correct winding structure is that the thread band 10 lies exactly along the cone line 21.
  • the warping carriage 22 is displaced in the X and Y directions, so that a winding structure 24 parallel to the cone 13b is produced.
  • the warping 9 is manually adjusted using the handwheel 16.
  • the warping process with the device according to the invention proceeds as follows: First, according to FIG. 4a, the threads 5 of the thread band 10 are guided through the warping reed 9 and provided with a knot 42 which is suspended in the warping drum 13.
  • the line camera 25 is only indicated in FIG. 4a.
  • the warping data Before the winding process can begin, the warping data must be entered at the operating station 27.
  • the data entered can be read off directly in display field 31.
  • the processor determines the required from the warping data derliche Bandwidth 11, which is automatically set on the Schwarzrriet 9 via the output line 34 and the servomotor 35.
  • the processor 32 stores this bandwidth as a setpoint with which the measured actual values are later permanently compared.
  • the processor 32 also controls the warping machine via the output line 33, in particular the speed of the warping drum or its start and stop and thus at the same time the displacement of the warping carriage 22.
  • the warping arm is brought into the basic position for winding the first band with the handwheel 36 via the linkage 37.
  • the first thread 19 must again be brought exactly to the interface between the cylindrical part and the cone of the warping drum.
  • the warping process can begin.
  • the warping drum 13 rotates at the desired speed and the threads 5 are drawn off from the warping frame 3.
  • the line camera 25 continuously measures the bandwidth 11 of the thread band 10 and feeds the determined values to the processor 32 via the input line 38. There, the determined values are compared with the stored target value, with deviations forming an actuating signal which is fed to the actuating motor 35 via the output line 34.
  • the servomotor changes the width of the sharpening rod 9 in the direction of the setpoint until the measured actual value again corresponds to the setpoint.
  • the processor 32 can be programmed such that an alarm signal is triggered and / or the warping machine is stopped.
  • This control loop eliminates interference during winding, so that winding can be carried out continuously with a practically constant bandwidth.
  • the permanent bandwidth control also has the advantage that the corrections to be made to the Schwarzrriet are not falsified by the standstill of the system. In addition, the operator is relieved of the demanding measurement and adjustment processes, so that human error sources are largely eliminated.
  • the system can also be controlled so that initially during a certain measuring period, e.g. when winding a first tape 14a, all the measured values determined by the line camera 25 are stored. From this, an average value is calculated, which serves as the setpoint for the control process when winding the following tapes. It would also be conceivable to drive the system semi-automatically, the Schwarzrriet 9 not being automatically adjusted. If there are too large deviations from a calculated mean value or from a predetermined target value, instead of activating the servomotor 35, only an alarm signal is triggered or the machine is stopped.
  • optical measuring device instead of the line camera 25, another optical measuring device could also be used for the contactless measurement.
  • a light source that emits a light beam, e.g. throws a laser beam onto a position-sensitive photo receiver.
  • Devices for optical measurement value acquisition are already well known to the person skilled in the art and are therefore not described in more detail here.
