Definitions

  • the invention relates to a method for traversing thread-like or ribbon-shaped winding material on winding machines for producing coils in a cross winding with wild or precision winding, by laying the winding material with a slot drum having a guide groove and winding it up to form a coil. An apparatus for performing the method is also shown.
  • Spuck is understood to mean any thread-like or ribbon-like material which can be wound up in the cross-winding process, starting from flat ribbons with a greater or lesser width and wires to the finest mono- and multifilament yarns of the textile and related industries.
  • Chiange is understood a movement of the winding material back and forth transversely to the winding direction, so that the piece of winding material currently running onto the spool is at a predetermined distance from the previously wound up winding material in a direction parallel to the axis of the spool.
  • a “grooved drum” is a drum with reverse thread grooves of a defined depth, ie with a groove base.
  • a "slot drum” is a mostly hollow drum that is divided into two parts by the reverse thread groove. It has no groove base, such a slit drum can preferably consist of sheet metal or a thin-walled tube section.
  • Axle-free slot drums made of solid material, in which two parts are arranged opposite one another, are also known.
  • the term grooved drum or roller is often used in the literature for slotted drums, so that the important difference in definition is not recognizable from the term itself.
  • a “guide groove” is a groove on a groove drum or a slot drum, with the aid of which the material to be wound is changed.
  • a “contact roller” is a roller which is arranged between a grooved drum or a slotted drum and a coil winding device, via which the winding material is fed to the coil winding device.
  • a method and a device of the type described at the outset, which thus work using a slotted drum, are from the book "Preparation Machines for Weaving, A Manual for Spinners, Weavers and Knitters" by Dipl.-Ing. J. Schneider, Springer-Verlag, Berlin / Göttingen / Heidelberg, 1963, pages 20 to 27, in particular pages 20 to 24, are known.
  • the slit drum used in this case has two parts, which have arisen from an obliquely severed pipe section, the mutually facing side edges of the two parts having a closed loop-shaped guide groove for the Form rinse aid.
  • the guide groove extends in a helical manner, and the material to be wound does not rest on a groove base, but extends through the guide groove from the entry point into the slot drum to the exit point from the slot drum.
  • the guide groove is a self-contained path without a crossing point.
  • the ware is guided on relatively narrow edges of the two parts, depending on the laying direction.
  • the relative friction speed occurring at the edge of the guide groove depends on the difference in the peripheral speed of the slit drum and the thread speed. With a corresponding direction of rotation of the slit drum, the friction speed is always lower than the thread speed.
  • the winding or laying of the material to be wound takes place solely through the slot drum or the guide groove between the two parts of the slot drum.
  • the oscillating masses are advantageously very small. Only the section of the material to be wound oscillates between a fixed point via which the material to be wound is fed and the respective point of contact of the material to be wound on the spool. The safety of the guidance of the winding material or the winding material thread is ensured both during the linear laying and in the reversal points by the loop-shaped closed guide groove without an intersection point. Swinging of the ware transversely to the laying direction advantageously does not occur. The sharpness of the reversal of the material to be wound on the side edges of the bobbin can be chosen as desired by the shape of the guide groove on the slot drum.
  • the friction speed between the winding material and the edges of the slot drum is less than the speed of the winding material.
  • the size of the free thread drag length from the exit point of the slit roller to a downstream contact roller or bobbin of a bobbin winding device is very small.
  • wear only occurs on the thread-carrying edges.
  • the manufacturing effort for such Slotted drums are advantageously small, so that conventional machine tools can be used.
  • a complex gear is not required and the manufacturing costs of such slotted drums are low.
  • the main disadvantage of these slotted drums lies in their size with regard to the diameter of the slotted drum. A large installation width requires a relatively large diameter of the slot drum.
  • the slope of the guide groove can only be increased up to a certain limit. If the pitch is chosen too large, the guide groove conveys the winding material out of the guide groove when driving the slot drum, so that the winding material thread is, as it were, removed to the outside from the slot drum, the traversing effect of course being lost. A certain maximum steepness of the guide groove must therefore be maintained or undercut in order to be able to guarantee the desired traversing action depending on the application, laying width and type of the ware. This limit of the slope of the guide groove cannot be exceeded.
  • Traversing devices of a different type namely in the form of grooved drums in the definition given at the beginning, are known for example from DE 42 37 840 A1 or also from DE 36 28 735 A1.
  • the ware is preferably guided on the groove base.
  • the rinsed material wraps around the groove base of the groove drum at a certain angle.
  • the guide groove of the grooved drum has one or more crossing points.
  • the jumping out or conveying out of the winding material from the guide groove and the associated change into the opposite section of the guide groove at the crossing points of the guide groove or also the conveying out of the winding material out of the guide groove of the groove drum is generally done by a complex design of the guide groove itself and in particular the intersection of the guide groove prevented by partially differing depths of the guide groove.
  • By wrapping the Items to be rinsed in the slot base of the slot drum have a certain amount of friction (rope friction) between the items to be rinsed and the slot base, the amount of which depends, among other things, on the difference between the (constant) speed of the items being rinsed and the (non-constant) peripheral speed of the slot base.
  • the outer circumferential surface of the slot drum is often used as a peripheral drive for the bobbin forming in the area of the bobbin winding device.
  • a contact roller is therefore unnecessary.
  • the winding ratio depends on the slot geometry and cannot be freely selected.
  • the friction (rope friction) described above also arises here, since here the peripheral speed on the outer diameter of the grooved drum is equal to the speed of the material to be wound and the peripheral speed in the groove base of the grooved drum is inevitably lower than the speed of the material to be wound.
  • the use of grooved drums has major disadvantages:
  • the partially differing groove depth of the guide groove causes the relevant section of the material to be swung transversely to the laying direction.
  • the size of the free tow length from the groove base to the contact roller or spool is relatively high.
  • the functional reliability of the grooved drum depends on the complex design of the shape of the guide groove, particularly at the crossing points. This high manufacturing effort can only be sensibly countered by using appropriate forms for the production of the grooved drums.
  • the manufacturing costs are dependent on the number of items, i.e. relatively high, especially for small numbers.
  • groove drums with an almost constant, relatively shallow groove depth are known, for example, from DE-OS 18 16 271, DE 39 01 278 A1 or DE 33 41 928 A1.
  • a traversing device is connected upstream of these grooved drums, this traversing device on the one hand providing the essential traversing function for the winding material and, on the other hand, also guiding the winding material over the crossing points of the guide groove of the grooved drum.
  • the advantage of the grooved drum is used to realize a sharp reversal in the area of the side edges of the coil, but the oscillating masses are disadvantageously increased by the corresponding mass fraction of the traversing device, which is disadvantageous in terms of wear and also in a limitation of those that can still be controlled Speed of the material to be washed.
  • traversing devices are known, the essential elements of which consist in a reversing thread roller and a thread guide.
  • the winding material is laid by the thread guide, who experiences its movement through the reversing thread roller, a shaft with an endless groove consisting of right and left-hand threads.
  • the movement of the thread guide in the two end positions is reversed through elbows connecting the threads.
  • the thread guide is braked in its end positions and accelerated again in the opposite direction.
  • the possible number of laying strokes per unit of time is limited by the mass of the thread guide and the size of the arch pieces.
  • the thread guide In order to achieve the greatest possible number of laying strokes per unit of time, the thread guide must have the lowest possible mass. Particularly at high traversing frequencies, there is high wear on the contact surface between the thread guide and the reversing thread roller for the thread guide.
  • the material to be wound is continuously guided on the thread guide with the aid of a slot or a similar shape, so that the relative speed of friction of the material to be wound at the edges of the slot corresponds to the speed of the material to be wound.
  • the main disadvantages of using a reversing thread roller and a thread guide lie in the increase in the oscillating masses and in the relatively high friction speed between the winding material and the thread guide.
  • the wear of the thread guide is relatively high and either only permits low speeds of the winding material or provides a short service life. Any sharpness of the path of the reversal in the area of the side edges of the coil is not possible.
  • traversing devices which work using thread guides which are driven by two oppositely driven chains or toothed belts. At least two thread guides are required, the winding material being guided by the thread guide currently active. An additional baffle is often required. The thread transfer from one thread guide to the other thread guide moving in the opposite direction is not exactly possible and is therefore prone to errors. The safety of the thread guide is neither guaranteed during linear laying nor at the reversal points. The oscillating masses are quite high. The speed of friction between the winding material and the thread guides corresponds to the speed of the winding material. A gearbox is absolutely necessary to implement the counter-rotation of the drive means.
  • winding machines with wing traversing are also known, for example from DE-OS 43 17 089 or DE-OS 37 03 731.
  • At least one pair of oppositely driven wings with a wing rotation axis perpendicular to the axis of the spool is used.
  • the wings guide the ware according to the direction of rotation along the bobbin width.
  • the material to be wound is guided by means of an arcuate guide.
  • the edges of the wings have a special shape. A mutual eccentric mounting of the axes of rotation of the wings ensures that the material to be wound is released at the transfer points from the previously thread-guiding wing to the opposite wing in order to be taken over by the latter.
  • a reversing gearbox is required to achieve the opposite direction of the wings.
  • the thread-guiding edge of the respective wing pushes the winding material in front of it.
  • the winding material is therefore not precisely guided and can run ahead of the wing edge.
  • the winding material is released from the thread-carrying wing before it is caught by the opposite wing.
  • the ware is not guided.
  • the curved guideline forces the material to be oscillated at right angles to the laying stroke, which can lead to uncontrollable vibrations of the material to be wound, particularly at higher laying speeds.
  • the oscillating masses are advantageously small, the safety of guiding the items to be wound is not guaranteed both during the linear laying and in the reversal points.
  • the speed of friction between the material to be wound and the edge of the wing corresponds to the speed of the material to be wound.
  • the wings must have a relatively large overall length.
  • a reverse gear for the opposite direction increases the effort.
  • the invention has for its object to provide a method and an apparatus of the type described above, with which the laying of a ware can be achieved using a slot drum, in which - apart from the ware - as far as possible no back and forth parts are used, so that the oscillating masses are as small as possible. Even with large installation widths, the cross-section of the installation device should not necessarily be enlarged.
  • this is achieved in the method of the type described in the introduction in that the material to be rinsed is laid with a slit drum consisting of at least three parts forming the guide groove and at least one crossing point, and in that the rinsing material entering the slit drum is conveyed through each crossing point of the guide groove an auxiliary device that forces an additional movement component in the direction of installation is guided on the material to be wound.
  • the invention is based on the idea of dividing the slit drum, which until now has only been in two parts, into at least three parts, so that the guide groove is formed by these three or more parts.
  • the guide groove In the case of a three-part slotted drum, the guide groove has an intersection point. In the case of a four-part slotted drum, the guide groove has two crossing points, etc. This gives the possibility of making the guide groove as wide as desired, without having to choose too large a slope for the guide groove. In other words, small diameters of the slotted drum can be realized even with a large installation width.
  • the winding material is laid exclusively by the slotted drum, which in turn has only rotatingly driven parts, ie does not increase the oscillating mass of the winding material.
  • the slot drum Since the slot drum has no groove base and the wall thickness of the slot drum is generally also relatively small, difficulties arise in the transfer of the material to be wound over everyone Crossing point of the guide groove.
  • the items to be wound are guided - only in the area of the transition over each crossing point - with an auxiliary device, which forces the items to be wound on an additional movement component in the respective laying direction. This has nothing to do with the traversing process.
  • the traversing function is still performed solely by the slot drum.
  • the auxiliary device is only effective at all in one or more relatively small route areas over the installation width. It is therefore also fundamentally possible or tolerable to use an auxiliary device which in turn has an oscillating mass. The stroke of this mass is only a small fraction of the laying stroke, and there is anyway the possibility of making the drive of the auxiliary device comparatively slower than the drive of the slot drum by the number of laying elements which the auxiliary device has.
  • the auxiliary device can be driven as a function of the slot drum, specifically in an integral, even part of the speed of the slot drum.
  • the speed of the auxiliary device is thus 1 ⁇ 2, 1 ⁇ 4, 1/6, 1/8, etc. the speed of the slot drum. From this, too, it can be seen that high working speeds can be achieved with the new method, so that even high speeds of the incoming winding material can be controlled.
  • the new method has the further advantage that it works safely and without problems. Vibrations across the direction of installation do not take place. The safety of the guidance of the winding material is both during the linear laying and in the reversal points guaranteed by the closed guide groove. Since the guide groove in the area of the reversal points on the coil side edges can be chosen as desired, sharp reversal points can also be reached, which promote proper coil build-up. The speed of friction between the material to be wound and the guide groove of the slot drum is less than the speed of the material to be wound. The size of the free tow length from the guide groove to the contact roller or to the spool is very small. Wear occurs in the area of the guide groove only on the thread-guiding edges.
  • the parts of the slot drum are relatively easy to manufacture on conventional machine tools.
  • the two end pieces of the slot drum can be of identical or largely identical design.
  • the center pieces of the slotted drum located between the end pieces can also be identical or largely identical to one another.
  • the diameter of the slot drum is (relatively) independent of the laying width. Even with small diameters, the guide groove can have a relatively large pitch and thus a laying width.
  • the device of the type described at the outset is characterized in accordance with the invention in that the slot drum has at least three parts forming the guide groove with at least one crossing point, that an auxiliary device is provided for forcing an additional movement component onto the winding material in the laying direction during the transition over each crossing point, that the Auxiliary device has at least two laying elements per crossing point, and that a drive is provided for the auxiliary device, which drives the auxiliary device with a speed corresponding to the speed of the slot drum, divided by the total number of laying elements per crossing point.
  • the new slot drum is extended or continued in the laying direction, as it were, compared to the previously known slot drums from two parts, so that the dependence between Installation width and diameter of the slot drum is no longer given.
  • the guide groove formed in this way extends in at least two circumferences around the casing of the slit drum, a crossing point being formed.
  • a slit drum consisting of five parts has three crossing points.
  • the auxiliary facility operates at the crossing over each crossing point.
  • the auxiliary device can be designed so that a separate auxiliary device is provided for each crossing point. However, it is also possible and of course sensible to provide a common auxiliary device for all crossing points in the case of several crossing points.
  • each crossing point has to be passed through alternately in one and the other laying direction, it makes sense to arrange at least one laying element on the auxiliary device for each laying direction.
  • the auxiliary device receives a speed that corresponds to half the speed of the slot drum. If four laying elements are assigned to a crossing point, the auxiliary device is driven at a quarter of the speed of the slot drum.
  • the auxiliary device can be designed so that it only has rotatingly driven parts. Due to the comparatively low speed, the speeds can be controlled at any time. There are no significant wear problems.
  • the auxiliary device can be provided outside the slot drum, it being connected upstream of the slot drum in the running direction of the winding material, that is to say influencing the winding material in the region of the entry point, but only for bridging the respective crossing point.
  • this auxiliary device essentially has a shaft on which two laying elements in the form of arms, brackets or the like are arranged. One laying element is assigned to one laying direction and the other laying element to the other laying direction.
  • auxiliary device is provided within the slot drum. This not only results in a protected design for the auxiliary device, but the entire device is relatively small.
  • the laying elements take effect inside the slit drum and influence the incoming part of the material to be wound.
  • the slot drum can have a continuous shaft via which the parts of the slot drum are connected to one another in a rotationally fixed manner.
  • the shaft offers an easy way to store the three parts of the slot drum and to hold them in their relative position to form the guide groove and the crossing point.
  • the shaft has no function with respect to the material to be wound, i. H. the thread usually does not come into contact with the shaft.
  • a type of modular system is also possible in this embodiment.
  • the parts of the slotted drum can be pushed onto a continuous shaft of a corresponding length and can be mounted in a rotationally fixed manner, a different number of middle pieces being able to be used in addition to the two end pieces of the slotted drum.
  • a reduction gear is provided between the slot drum and the auxiliary device, which is designed depending on the number of laying elements.
  • This reduction gear can also be accommodated either outside the slot drum or inside the slot drum.
  • the auxiliary device can have two shafts driven in opposite directions, which are provided with laying elements. It is understood that the one wave with the associated laying element or elements of one laying direction and the other shaft of the other laying direction.

  • the end pieces 2 are of identical design.
  • the end pieces 2 and the middle piece 3 are rotatably mounted on a common continuous shaft 4 and held in the relative position shown to each other.

  • the guide groove 5 is open in the radial direction, i. H.
  • the guide groove 5 has a crossing point 6 and two reversal points 7.
  • the course of the guide groove 5 intersects at the crossing point 6.
  • the laying direction 8 changes, which is indicated by a double arrow parallel to the axis of the shaft 4.
  • the laying width 9 is determined by the distance of the two reversal points 7 from one another.
  • FIG. 1 shows the combination of two end pieces 2 with a middle piece 3, with a crossing point 6 being created. It is easy to imagine that two end pieces 2 can be combined with two middle pieces 3 in order to increase the laying width 9.
  • the center pieces 3 are then again identical, at least in the course of their edges forming the guide groove 5, and arranged on the shaft 4 rotated by 180 °.
  • This system can be expanded.
  • the number of crossing points 6 coincides with the number of middle pieces 3 used. In other words, a three-part slotted drum has one crossing point, a four-part slotted drum 1 has two crossing points 6, etc.
  • FIG. 2 shows the slotted drum 1 according to FIG. 1 again in a schematic plan view, but rotated through 90 °, so that the crossing point 6 of the guideway 5 is visible in a full central plan view.
  • the slit drum 1 is associated with an auxiliary device 10, which does not have any laying function for the definitive laying of the items to be wound on the bobbin, but merely has the task of ensuring that the crossing point 6 is exceeded while maintaining the laying direction 8.

  • a reduction gear 39 is provided between shaft 4 and base body 20, the essential components of which are formed by a sun gear 40, two planet gears 41 and 42, an output gear 43 and a weight body 44.
  • the sun gear 40 is arranged in a rotationally fixed manner on the shaft 4 of the slot drum 1 and thus rotates according to the speed of the shaft 4.
  • the weight body 44 is rotatably suspended on the shaft 4 with the aid of a ball bearing 45.
  • the weight body 44 does not rotate. It hangs on the rotating shaft 4 and forms the bearing for the axes of the two planet gears 41 and 42.
  • the planet gear 41 is in engagement with the sun gear 40, while on the other hand the planet gear 42 meshes with the planet gear 41 to reverse the direction of rotation.
  • the planet gear 42 finally engages in the driven gear 43, which in turn is non-rotatably connected to the base body 20 of the auxiliary device. With appropriate geometric design, the reduction to half the speed is also brought about here.
  • the base body 20 with the two laying elements 21 and 22 rotates at half the speed in relation to the speed of the shaft 4.
  • the direction of rotation of the shaft 4 and thus of the casing of the slot drum 1 coincides with the direction of rotation of the base body 20 of the auxiliary device 10, namely in the direction which is also determined by the arrow 12 of the incoming material 11.
  • FIG. 8 Another embodiment of the device is shown in FIG. 8.
  • Essential parts of the auxiliary device 10 are also accommodated here within the slot drum 1, such as the base body 20, which carries the two laying elements 21 and 22.
  • the base body 20 is also freely rotatable on the shaft 4 of the slot drum 1 by means of the two ball bearings 37 and 38.
  • the shaft 4 is driven by a motor 46, the axis of which is provided in alignment with the axis of the shaft 4.
  • Only the drive for the auxiliary device 10 and the elements required for it are arranged outside the slot drum 1. So is a drive wheel 47, for. B. in the form of a gear or a pulley rotatably placed on the shaft 4 and connected to it.
  • the drive takes place on an output gear 48, which is arranged on an intermediate shaft 49.
  • a drive wheel 50 which cooperates with an output wheel 51 which is arranged on the shaft 4 in a freely rotatable manner by means of a ball bearing 52.
  • the dimensioning of the drive wheels 47 to 51 is selected so that the corresponding reduction for the speed of the auxiliary device 10 takes place as a function of the speed of the slot drum 1.
  • two laying elements 21 and 22 are again provided for the crossing point 6, so that the base body 20 of the auxiliary device is to be driven at half the speed of the shaft 4 or the slot drum 1.
