Definitions

  • the invention relates to a winding machine for winding a thread into a package according to the preamble of claim 1.
  • the winding machine is known from DE-OS 1 710 068.
  • a winding machine which also consists of two traversing devices.
  • motion laws for the first and second traversing device are specified, essentially with the content that the stroke lengths are essentially the same and that the first traversing device is operated with temporary acceleration before or after the stroke reversal with only a slight change in speed , while the groove profile of the grooved roller in the stroke reversal causes a sudden change in speed.
  • These laws of motion also apply to the traversing device according to the generic term. It has been found, however, that when a so-called wing traversing is used as the first traversing device, the motion law according to the invention can also be used and causes exact thread guidance.
  • the first traversing device - in the course of the thread - is developed in such a way that the guide ruler upstream or downstream of the driver arms and the driver arms are assigned to one another and shaped in such a way that the driver arms give the thread an overstroke.
  • the guide stroke of the first traversing device is greater than the traversing stroke of the subsequent second traversing device, which is designed as a grooved roller, and essentially corresponds to the coil length.
  • the guide and driver arms are designed in accordance with the invention in such a way that the thread receives a very high acceleration in the opposite direction at the end of the guide stroke, so that it suddenly reverses its direction of movement and is moved back towards the center of the traversing stroke with extremely high acceleration and speed until it reaches the entry point into the Groove with approximately the routing angle.
  • the thread is then guided in the central region of the guide stroke essentially at the traversing speed of the grooved roller.
  • the first traversing device at the stroke reversing points with a slight change in speed and before and / or after the stroke reversing points is sometimes guided at a greater speed than the speed maintained in the central region of the traversing stroke and the stroke length of the first traversing device is approximately equal to the stroke length between the thread guide grooves
  • the required law of motion of the first traversing device can be achieved by designing the guide ruler upstream or downstream of the driver arms and the driver arms at their thread-guiding ends (cf. e.g. DE-PS 1 560 469).
  • This shaping is preferably carried out in the stroke reversal areas in such a way that the thread is guided to the end of the guide stroke at the speed which is also maintained in the middle area of the traverse stroke and then reversed in its direction of movement with very great acceleration and is so far traced back to the law of motion observed in the middle traverse stroke area that it leads to the entry point of the groove with approximately the laying angle.
  • this return can take place in that driver arms and guide ruler are designed in such a way that the positive guidance of the thread is briefly released when the end of the guide stroke is reached, so that the thread snaps back under its own thread tension into that through the grooves of the grooving roller given motion law of the middle stroke range.
  • the thread does not fall out of the grooves of the grooved roller, but is guided through the first traversing device in such a way that this does not occur.
  • the large overstroke provided according to the invention is required in particular.
  • This overstroke (Ü) is essentially equal to the drag length (L) x tangent alpha, where alpha is the laying angle of the thread on the bobbin, i.e. is the angle between the tangent lying in the normal plane and the thread.
  • the shortest distance between the lines of thread engagement of the first and the second traversing device is called the drag length.
  • Ü L x tan alphan.
  • Fig. 1 shows the cross section
  • Fig. 2 shows the view of an embodiment of the winding machine according to the invention, partially schematically.
  • the thread 3 running continuously in the direction of 2 is first passed through the stationary thread guide 1 and then through the traverse 4.
  • the winding spindle 5 is freely rotatable.
  • An empty tube 10 is slipped onto the winding spindle 5.
  • the thread 3, which runs at a constant speed, for example freshly spun and / or drawn man-made fibers, is wound on the empty tube 10 to form a cheese 6.
  • the empty tube 10 and then the coil 6 that is formed are driven at their circumference by a drive roller 21 (not visible in FIG. 2) at a constant circumferential speed.
  • the thread 3 is moved back and forth along each cross-wound bobbin by the traversing 4, which is described below.
  • the traversing mechanism 4 and the drive roller 21 are mounted together on a carriage 22, which can be moved up and down on guide rods 24, so that the drive roller 21 can avoid the growing coil diameter of the coil 6.
  • the weight of the carriage 22 is partially due to the support device 23 - here a cylinder-piston unit compensated.
  • the carrying device can be controlled in such a way that the carriage with the drive roller 21 lifts off the coil circumference.
  • the traversing 4 consists, on the one hand, of a wing traversing and, on the other hand, of a grooved roller 11 arranged downstream of this in the thread path.
  • the traversing has its own drive, not shown.
  • Wing traversing and grooved roller are connected in a geared manner (not shown).
  • the particular advantage of the traversing shown is that the depositing angle of the thread on the spool can vary - within limits - from the angle of inclination of the slots, since the traversing speed can be set independently of the spooling speed.
  • the wing hinge has the rotor 12 and the rotor 13. Both rotors can be mounted concentrically or eccentrically to one another. Both rotors are driven in opposite directions by a drive and gear, not shown, in gear housing 20.
  • the rotor 12 carries two or three or four driver arms 8 which rotate in the plane of rotation 1 (arrow 18).
  • the rotor 13 carries the same number of driver arms 7 which rotate in the closely adjacent plane of rotation 11 (arrow 17).
  • the driver arms guide the thread along the guide ruler 9. Each driver arm 8 transports the thread - in FIG. 2 - to the right and transfers it there at the guide end to a driver arm 7, which transports the thread in the opposite direction to the other guide end, where in turn one of the driver arms 8 takes over the return.
  • the grooved roller 11 has a grooved train. It should be noted that the groove depth changes in the course of the grooves.
  • the grooves preferably form an uninterrupted groove train. However, it can also be provided that the grooves run out on the surface in the central region of the groove roller.
  • the grooved roller is driven synchronously with the wing traversing in the illustrated case with a transmission ratio 1:20.
  • the law of motion with which the thread 3 is deposited on the bobbin 6 is essentially predetermined by the course of the groove train.
  • the law of motion with which the thread is guided back and forth through the driver arms 7, 8 is - as stated - predetermined by the geometry of the ends of the driver arms and the guide rule 9.
  • the law of motion is determined on the one hand by the constant peripheral speed of the driver arms.
  • the thread also executes radial movements with respect to the driver arms, which are predetermined by the shape of the guide ruler.
  • the curves 25 to 33 are path-time diagrams of the thread movement, the common abscissa being the traversing stroke H of the grooved roller or the guiding stroke F of the first traversing device, and each of the two curves being a separate time Has ordinates which are shifted relative to one another in such a way that a stroke difference of approximately the amount U results between two thread points in the first and second traversing device considered at the same time.
  • Fig. 3 the curve 25 (groove course) shows the geometry of a thread guide groove of the grooved roller at the right stroke end of the traversing stroke H.
  • the theoretical stroke end lies at point 26, which essentially also denotes the bobbin length.
  • the groove is led slightly beyond this theoretical stroke in the branch 27 in order to take into account the fact that the thread deposited on the bobbin tends to slide inwards.
  • Curve 30 shows a part of the law of movement of the back and forth, which is given to the thread by the driver arms 7, 8. It can be seen from this that the guide stroke F of the first traversing device is greater than the traversing stroke H. This difference is also called the carryover of the thread; it is labeled U. The difference is proportional, on the one hand, to the distance L, which exists between the guide ruler 9 or the planes of rotation I, 11 of the wings and the surface line of the grooved roller 11, in which the thread runs onto the grooved roller, and, on the other hand, to the depositing angle alpha. The distance L, also referred to as the drag length, is practically measured from the center plane between the rotation planes 1 and II.
  • the angle alpha between the groove between the groove of the grooved roller and the tangent to the grooved roller is referred to here.
  • the thread is first guided at a speed (branch 31) to the end of the guide stroke F, which essentially corresponds to the traversing speed of the thread deposit according to branch 28 of the curve 25 of the grooved roller, but with a forward run substantially corresponding to the distance U.
  • the thread is braked with an extremely high change in speed and reversed in its direction of movement, so that it moves back at an excessive speed in the curved branch 32 into an area 33 which essentially, i.e., with the curved branch 29 of the grooved roller. aligns with the possibility of a small angle of deviation.
  • the path of the stroke 33 of the first traversing device in the middle stroke range corresponds to the thread deposit 29 after the reversal of the stroke with a phase-shift in phase, so that at the same time the first traversing device is essentially ahead of the distance U of the second traversing device.
  • the strong delay and acceleration of the thread at the end of the guide stroke is achieved either by positive guidance or by releasing the thread. Suitable measures are shown in FIGS. 4 and 5.
  • the thread is deflected at the ends of the guide stroke F between the guide ruler 9.1 and the curved guide ruler 9.2, which, as shown in FIG. 4, are arranged one above the other in the thread run.
  • the guiding lines overlap. This overlap ends in an end region E.
  • FIG 5 shows a top view of the end pieces of the driver arms 7 and 8 and the guide rulers 9.1 and 9.2 in the end region of the guide stroke F of the first traversing device.
  • the thread can therefore perform an unhindered or only slightly hindered return in the region E from the end of the guide stroke in the direction of the center of the stroke.
  • the intensity of the free return depends on the thread tension.
  • the free mobility of the thread allows very high decelerations and accelerations to be exerted on the thread, so that in the area of the free return a movement law approximately corresponding to the curve branch 32 according to movement law 30 in FIG. 3 is achieved.
  • the return movement is braked, so that the pushing edge 34 of the driving arm 8 entering the guide stroke can catch up with the thread and take over and guide with a guide length which is sufficiently superior to the guide ruler 9.1.
  • the thread is then forcibly guided again by the pushing edge 34 of the driving arm 7 according to a predetermined law of motion in accordance with the curve branch 33 of the law of motion 30 according to FIG. 3.
