Definitions

  • the invention relates to an arrangement for winding textile threads from bobbins of a creel on a warp beam of a warping or warping machine, with an adjustable thread braking device for each thread, which has two rolls lying against one another with pretension on the circumference, at least one of which has a covering made of elastic Has material and which are driven by the thread drawn between them, with a brake adjusting device acting on all thread braking devices to change the pretension.
  • the thread brake devices provided with rollers are also well suited for yarns or threads of different types and strengths. All known yarns from e.g. tex 2.8 Glass fiber up to tex 1 000 for staple fibers and synthetic continuous yarns.
  • a device of the type described in the opening paragraph is known from German published patent application DE-A1-2 534 364. In such a device, the pretensioning of two adjacent rolls determines their rotational resistance caused by the flexing of the elastic coating when the thread is pulled through, and thus the tension of the thread pulled through . This thread tension must not exceed a certain value, so that the thread does not break during winding. The pre-tension of the brakes is adjusted according to the maximum permissible thread tension value.
  • the pretension is adjustable, but the value of the pretension that was set once cannot be changed during winding operation.
  • a comparatively cumbersome determination of the highest thread running speed for the thread in question is required, in which winding can still be expected without breakage.
  • the user of the arrangement consisting of warping machine and creel proceeds in such a way that the thread running speed is increased or reduced while the system for adjusting the thread brakes is stopped until there is winding without breakage.
  • This arrangement is particularly disadvantageous if yarns of different types and sizes are to be warmed in a short succession, that is to say multiple attempts are necessary.
  • the invention has for its object to provide an arrangement of the type mentioned, which enables easy determination of the highest production during winding or the highest thread break speed or winding speed with minimal downtime of the arrangement.
  • winding speed is used instead of the expression thread running speed, since the latter is essentially determined by the winding speed of the warping or warping machine.
  • winding speed present on the thread braking devices is variable during the winding operation of the warping or warping machine after the start-up, independently of the thread order increasing during winding on the warp beam, and that the brake adjustment device can be controlled automatically with the aid of a thread tension measuring device.
  • the disadvantages described above are avoided, e.g. the balloon formation of the drawn thread between the bobbin of the discharge gate and the thread braking device or its inlet eye is a good criterion for whether the winding speed can still be increased.
  • Such slack thread tension measuring devices usually give electrical measurement signals, so that it is advantageous if the brake adjusting device has an electric adjusting motor which engages an adjusting linkage which adjusts the pretension of all thread braking devices, since a measurement value conversion can then be avoided.
  • the brake adjusting device has an electric adjusting motor which engages an adjusting linkage which adjusts the pretension of all thread braking devices, since a measurement value conversion can then be avoided.
  • there is a regulating device which is able to compare an electrical actual value transmitted by the thread tension measuring device with a preset electrical target value and to act on the electric adjusting motor in the presence of a target / actual difference in the sense of keeping the thread tension constant.
  • FIG. 3a, b of the Fig. Corresponding representation of a thread tension measuring and control device for a creel with two independent sides of the gate to be influenced.
  • the winding or warping machine 13 has a warp beam 13 'on which the threads 12 coming from the creel 18 are to be wound up in an orderly manner by being pulled off a creel 18 with the aid of a not shown drive of the warp beam.
  • the bobbin creel 18 has a large number of bobbins with bobbins 1.
  • Each thread 12 runs from a bobbin 1 through an inlet eyelet 17 to a thread braking device 2, through which it is deflected by 90 ° and from which it passes the warp beam via thread guide eyelets 19 (not shown) 13 'is supplied.
  • each thread brake device For orderly winding, the thread braking devices 2 generate in each thread 12 the required thread tension or the counterforce that must be applied by the warping machine by means of a corresponding tensile force.
  • Each thread brake device consists of a pendulum-like roller 2 'mounted on a holding rail, not shown, which is pressed or pulled against a fixed roller 2 ".
  • both rollers When the thread 12 is pulled through a thread brake device, both rollers are set in rotation. Since at least one of the both rolls has an elastic coating, this is tumbled, since it bears against the other roll under prestress, so that a corresponding rotational resistance arises, which must be overcome when the thread is pulled through the thread braking device, which creates the thread tension.
  • the bias with which both rollers 2 ', 2 "lie against each other is determined by a spring 20, which engages on the one hand on the pendulum-like roller 2' and on the other hand on an adjusting ring 21, so that the spring force and thus the bias with which the the two rollers lie against each other, can be adjusted by moving the steep ring 21 on an adjusting rod 22.
  • the adjusting rod 22 also guides the spring 20.
  • Each coil level, for example 24, of the coil gate 18 is assigned an adjusting rod 22, which has all the adjusting rings 2 and springs 20 of this coil level. All adjusting rods 22 are ari-steered on the thread run-off side of the creel shown to a brake adjusting device 25 attached there, with which they can be moved horizontally together by an electric adjusting motor 7 in the sense of changing the pretension of the thread braking devices.
  • the brake adjusting device 25 or its adjusting motor 7 has an adjusting nut 5 seated on an adjusting spindle 8, which can be adjusted in the directions of the double arrow, since it cannot be rotated on the frame frame 23 in a manner not shown hold is.
  • the main adjustment 6 is rotated about a pivot axis 6 ', so that it lifts a connecting bracket 9 with a short angle arm, not shown.
  • the connecting tab 9 is in turn articulated to Winkelhebei 10, which establish the operative connection to the actuating rods 22.
  • Each angle lift 110 is articulated at an apex pivot point 10 ′ and connected to the adjusting rod 22 via an elongated hole 10 ′′.
  • piston rod 4 'of a piston-cylinder drive 4 is articulated at the upper end of the main adjusting lever 6, which in turn is articulated to the frame 23 of the creel 18.
  • This piston-cylinder drive 4 is used for rapid braking of the thread braking devices, so that their rollers 2 ', 2 "do not continue to run when the warp beam 13 is suddenly braked and the threads 12 are pulled off.
  • the thread 12 'of the bobbin 1' is used to measure the thread tension by means of the thread tension measuring device 11.
  • This has a tensile force measuring head in which the thread 12 'wraps around the thread guide 11' and the pressure transmitter 11 "in the sense shown.
  • the tensile force measuring head can advantageously be provided with a strain gauge so that measurements can be carried out practically without a path.
  • a thread slack causes e.g. by a measuring wheel or by a support arm sliding on the thread does not occur.
  • the measurement signal emitted by the thread tension measuring device 11 is fed to a regulating device 15.
  • the control device 15 contains e.g. a PIV three-point controller, which compares the measurement signal supplied to it with a target value, which is set by a potentiometer 18 on the warping machine. If there is a target / actual difference, the electric adjustment motor 14 is acted upon accordingly and adjusts all the thread brake devices 2 with the aid of the centrally acting brake adjustment device 25.
  • the arrangement for winding textile threads 12 can be operated in such a way that the speed of rotation of the warp beam 13 'or the winding speed of the warping or warping machine is increased continuously or step-wise independently of the thread application onto the warp beam which is washed during winding until the maximum possible thread pulling speed is present on the braking devices 2.
  • This is e.g. determined by the thread balloons 1 "of the threads 12 or 12 ', since with a further increase in the winding speed, the thread balloons 1" would become so large radially that neighboring thread balloons would collapse and thread breakage would occur.
  • the thread tension or the tensile force of the threads 12, 12 'on the thread 12' is measured during the seamless or gradual start-up. If the measured value of the thread tension exceeds the thread tension value specified by the potentiometer 16, the above-described regulation takes place with the aid of the control device 15 and the electric adjustment motor 7, which adjusts all the thread brakes 2 with the brake adjustment device 25 so that the preselected thread tension value is reached again.
  • the thread tension measuring device basically makes do with the measurement on a thread 12 ', since a thread monitoring device is regularly present on the gate, which monitors each individual thread and stops the warping machine in the event of a thread break. For safety reasons, however, several thread measuring devices can also be used. This is recommended e.g. then when yarns of different types and sizes are to be wound onto the same warp beam from a creel. Then it is e.g. advantageous to use a creel with two sides of the gate, each having a separate thread tension measuring, control and brake adjustment device. 3a, b then show the arrangement and effect of the thread tension measuring and control devices for the left and right side of the gate, which e.g. have different threads 12 ', 12 "according to type and strength.
