Definitions

  • the invention relates to a device and a method for balloon limitation on a creel according to the preamble of patent claims 1 and 15.
  • DE-A1-28 41 210 shows a balloon limiter with a resiliently deflectable limiter rod.
  • a device for breaking thread balloons is known, in which rods are provided with balloon interference elements.
  • a helical balloon limiting element is provided in the area between the end face of the bobbin and the thread brake.
  • closed balloon limiters in which the thread is surrounded, for example, by a spiral guide element, are relatively expensive to operate and produce.
  • magazine gates in which a passive or reserve coil is provided for each active coil, the beginning of which is linked to the end of the active coil in order to ensure continuous operation, such closed balloon limiters cannot be used.
  • the object of the invention is to provide a device and a method for balloon limitation, which avoid the disadvantages of the known and can be produced in a simple and reliable manner and can be adapted to a wide variety of forms of balloon formation.
  • the invention achieves a balloon limitation for a large number of coils in an optimally simple manner with two horizontally arranged separators.
  • the separators form guide planes for the thread or the balloon formed by the thread, by means of which a two-sided delimitation of the draw-off space in front of the bobbins is formed.
  • the draw-off space in front of the bobbins, in which balloon formation occurs, tapers from the front side of the bobbins in the thread running direction.
  • the guide plane of the separators on its thread inlet side facing the bobbin face has a distance from the fictitious extension of the bobbin axis that is greater than the maximum radius of the bobbin face. This reliably prevents the thread from rolling over in front of the separator and a balloon forming outside the separator.
  • the invention can be further optimized if the guide planes of the separators on their side facing away from the end face of the coil are at a distance from one another which is equal to or less than half the maximum diameter of the coil.
  • the thread friction in particular can be minimized if the guide plane is inclined at an angle of 40 ° to 50 °, preferably of approximately 45 °, to the longitudinal axis of the bobbin.
  • the management level is particularly easy to use thanks to a flat guide element, e.g. form a U-shaped flanged sheet metal element, the element being arranged at an angle to the coil axis.
  • Each management level can also be formed by two or more individual elements. In this way, e.g. arrange individual elements that can be moved into each other so that the width of the guide level can be adjusted and adapted to a specific thread.
  • the adaptability can be further improved if the inclination of the guide plane to the longitudinal axis of the coil is adjustable.
  • a particularly reliable guiding property of the guiding element results if the width of the guiding plane in the thread running direction is at least 48 mm. In practical use, there are particularly advantageous values with a width of at least 80 mm and at most 140 mm, preferably of about 100 mm. It can be advantageous here if the width of the guide plane can be adjusted in the direction of the end face of the coil and / or the side facing away from the end face of the coil.
  • a magazine gate 1 shown schematically in plan view, has a coil board 2.
  • the coil board 2 consists of an arrangement of coils 3, which are placed next to each other and one above the other in horizontal and vertical rows.
  • Active bobbins 3a, 3b, 3c and 3d are shown, from which the threads 4 are drawn off and guided in the associated thread tensioners 5a, 5b, 5c and 5d, deflected and fed to the winding machine (not shown).
  • a winding machine e.g. a warping machine or a warping machine etc. can be provided, to which the threads are fed as a thread assembly.
  • each of the active coils 3a, 3b, 3c and 3d is assigned a reserve coil 7a, 7b.
  • the end of the respectively active coil is linked by a connection 8a, 8b to the start of the assigned reserve coil 7a or 7b.
  • the thread 4 is automatically drawn off the reserve bobbin, so that the empty bobbin (represented by bobbin tube 9) can be replaced by a full bobbin, which then serves as a reserve bobbin.
  • the rotating arms 11 can be pivoted so that the empty bobbin tube 9 is removed and a new coil 3 can be plugged on.
  • the rotating arms 11 are mounted on vertical supports 12. They are blocked by means not shown in their operating position and in the plug-on position. They can be swiveled easily by the operating personnel without any effort.
  • an active spool 3a, 3b and the associated passive spool or reserve spool 7a, 7b are each aligned with their spool axis on a common thread tensioner 5a or 5b.
  • the thread 4 therefore runs alternately from one of the two bobbins through the common thread tensioner 5a or 5b.
  • a thread balloon which is indicated at 13, develops between the thread tensioner 5a, 5b, 5c, 5d and the associated bobbins 3.
  • the spacing of the bobbins 3 from one another in the horizontal direction is so great that the threads 4 or the balloons 13 in front of the individual thread tensioners 5 can neither touch one another nor get tangled with the respectively adjacent bobbin.
  • the vertical distance between the different coil rows 3 is relatively short.
  • horizontal separators 17a, 17b are therefore provided, which are held in vertical slots 16 in corresponding slots 18.
  • the U-profiles 16 are fastened together with the spool panel 2 and the brake panel 14, which carries the thread tensioner 5, on a creel frame 15.
  • the separators 17a and 17b are designed as elongated sheet metal strips which have U-shaped rounded portions 19 on both sides. These roundings or bevels 19 stiffen the sheet metal strips on the one hand in such a way that they can be kept free between U-profiles 16 even over greater distances, for example two or three meters. On the other hand, the roundings have the effect that the threads 4 cannot get caught and are not chafed.
  • the separators 17a, 17b therefore delimit a draw-off space 20 in front of each bobbin, through which the thread 4 is drawn off from the associated bobbin 3.
  • the separators 17a, 17b are arranged obliquely to the bobbin axis 3x or the fictitious extension of the bobbin axis in such a way that the draw-off space 20 tapers towards the thread tensioners 5 in the thread running direction.
  • the balloon 13 is thereby limited in such a way that on the one hand it ensures reliable alignment with the thread tensioner 5 and on the other hand it prevents the balloons of the rows of coils lying one above the other from being touched and tangled.
  • the separators 17a, 17b can be divided into sectors depending on the gate length. It is expedient for there to be a separation per gate field (a gate field can correspond to the length of one to three meters, for example).
  • the separators can also be used for other types of gates with horizontal coil rows and of course also for carriage gates. They are particularly advantageous for use with horizontally swiveling coil holders and for gates with reserve attachments according to the exemplary embodiment, in which access to the coil is guaranteed from the rear.
  • the separators Due to the lateral mounting in the slots 18 of the U-profiles 16, the separators can be easily installed and removed. It is also e.g. possible to use different separators to e.g. to accommodate wider or narrower separators in adaptation to coils of different diameters. It is also conceivable to change the angular inclination of the separators to the coil axis 3x by exchanging the U-profiles or by using special separators.
  • Figure 3 shows an embodiment in which two schematically illustrated separators 17a, 17b at an angle ⁇ are inclined 3x to the coil axis 3x (in the exemplary embodiment according to FIGS. 1 and 2, the angle ⁇ is approximately 45 °).
  • the distance a between the separators 17a, 17b on their side facing away from the coil 3 is slightly smaller than half the maximum diameter d of the coil 3.
  • the distance b between the separators 17a, 17b in the region of the end face of the coil 3 is somewhat larger than that Maximum diameter d. This ensures that the balloon formation by the separators 17a, 17b is reliably controlled during the entire winding process from the largest to the smallest diameter d.
  • FIG. 4 shows schematically how both the inclination and the relative position of the separator 17a with respect to the end face of the coil 3 can be changed by means of a pivotable arrangement of a separator 17a in positions I, II and III (by holding means not shown).
  • the second separator 17b can either also be designed to be pivotable or be arranged in a fixed manner if, for example, the extraction space 20 should only be variable on one side (by separator 17a).
  • FIG. 5 shows an embodiment in which the separator 17a consists of two individual elements 21, 22.
  • the element 22 can be inserted into the element 21. If the width c of the separator 17a is now to be changed in order to adapt the separator to a specific thread, the element 22 can simply be pulled out of the element 21 and thus moved from position I to position II. This increases the width and the trigger space 20 is correspondingly more limited.
  • the angle ⁇ is approximately 60 °.
  • the width c of the separator 17a can be changed between 80 mm and 120 mm by pulling out.
  • the two elements 21, 22 can be fixed in their relative positions to one another by any clamping or holding devices, so that the set and desired width of the separator is reliably maintained.
  • a swiveling device can of course also be provided, so that the angle ⁇ can also be adjusted analogously to the embodiment according to FIG. 4.
  • Corresponding holding devices on the U-profiles 16 can easily be realized by skilled persons using manual means.
  • the second separator 17b is also not shown in the exemplary embodiment according to FIG. 5 for the sake of simplicity.
  • the separator 17a consisting of the two individual elements 21, 22 can also be produced from several individual elements.
  • the separator 17a consists of three individual elements 21, 22 and 23.
  • the elements 21 to 23 are hollow profiles which engage with one another with a tongue and groove connection in such a way that they form a guide plane for the thread 4 or the balloon 13 drawn off.
  • the width of this management level can be adapted to the requirements by adding or leaving out individual elements.
  • the guide plane can be designed to be curved by arranging the individual elements 21, 22, 23 in a correspondingly angled manner, as is indicated in FIG. 6.
