Definitions

  • the invention relates to a method for winding up a continuously running thread according to the preamble of claim 1 and an apparatus for carrying out the method according to the preamble of claim 14.
  • the thread When winding a thread into a package, the thread is deposited on the surface of the package within the package width at a substantially constant circumferential speed of the package with an angle of intersection. For this purpose, the thread is guided back and forth within a traversing stroke by a traversing thread guide before it hits the bobbin surface.
  • the length of the traverse stroke determines the spool width.
  • a basic distinction is made between two known methods for forming a coil. In a first method, the maximum length of the traversing stroke is not changed during the winding travel. A cylindrical cross-wound bobbin with essentially rectangular end faces is thus wound.
  • the length of the traverse stroke set at the start of the winding travel is equal to the length of the traversing stroke at the end of the winding travel.
  • the traversing stroke is continuously shortened during the winding cycle.
  • a cylindrical cheese is wound with sloping faces.
  • These so-called biconical coils are therefore erased from a normal plane, the angle of repose being less than 90 °.
  • the traversing stroke set at the end of the winding travel has a length which is less than the length of the traversing stroke at the beginning of the winding travel.
  • the thread layers must be laid at the ends of the bobbin when reversing the thread so that no irregularities arise from, for example, emerging pieces of thread such as the so-called thread stopper or slipping thread layers.
  • EP 0 235 557 (Bag.
  • This object is achieved according to the invention by a method with the features according to claim 1 and by a device with the features according to claim 14.
  • the invention is characterized in that all the layers of threads of a package lying one above the other are included in the shaping of the end faces.
  • the invention breaks with the prejudice that during winding to produce a right-angled or inclined face of the spool, the traversing stroke is to be changed in proportion to the spool width during the spool travel. It was found that the design of the end face of the package is not determined solely by the lengths of the traverse stroke set during winding, but rather results from the interaction of all the layers of threads lying on top of one another after the bobbin is finished. Changes are found, particularly in the middle diameter range of the coil.
  • Such changes in shape are taken into account by the method according to the invention by changing the lengths of the traversing stroke during the winding travel according to a predetermined lifting function.
  • the stroke function specifies the relationship between the winding, which can be defined by the winding time or the spool diameter, and the lengths of the traversing stroke to be set in each case. In this case, a certain length is assigned to each traversing stroke in the course of the winding travel by means of the lifting function, the lengths of the traversing strokes being smaller than the respectively wound bobbin widths.
  • the lifting function can also be viewed as a measure which indicates the difference between the later spool width and the length of the traversing stroke.
  • a stroke function is particularly advantageous for the formation of rectilinear end faces, in which a steady shortening of the traversing stroke relative to the spool width is specified at the beginning of the spool travel and a steady extension of the traversing stroke relative to the spool width at the end of the spool travel.
  • the greatest deviations between the coil width and the length of the traversing stroke thus result in particular in the middle area.
  • the traverse stroke changes given by the lifting function over the winding travel are essentially dependent on the parameters such as thread tension, the crimping of the thread, the thread titer, the bobbin density and the thread placement, which is defined by the crossing angle and the thread reversal.
  • connection has been found, for example, that a textured thread with a relatively low crimp needs a lifting function which shows a greater deviation between the bobbin width and the length of the traversing stroke in the central region of the bobbin.
  • a lifting function which shows a greater deviation between the bobbin width and the length of the traversing stroke in the central region of the bobbin.
  • only a slight deviation between the coil width and the length of the traversing stroke is required.
  • a specific length of the traversing stroke is assigned to each wound bobbin diameter during the winding travel. This enables a very precise geometric shape of the cheese to be produced and reproduced.
  • the method variant according to claim 6 should preferably be used.
  • the shape of both end faces can be wound differently.
  • a lifting function assumes a maximum length of the traversing stroke set at the start of the winding travel and an end length of the traversing stroke set at the end of the winding travel, the lifting function is specified for a final diameter or a slope angle.
  • each winding end diameter of a package is assigned a lifting function, which results in a certain angle of repose on at least one end face of the package.
  • each slope angle of the cheese is assigned a lifting function.
  • Each of the lifting functions is set to a specific end diameter of the package.
  • the maximum length of the traversing stroke at the start of the winding cycle and the end length of the traversing stroke at the end of the winding cycle are each given the same size.
  • any desired angle of repose can be set on the end face of the coil by shortening the end length of the traversing stroke.
  • the lifting function is stored and stored in a control device.
  • the control device is connected to the drive of the traversing thread guide, the drive influencing the traversing movement and the traversing stroke of the traversing thread guide.
  • the stroke function could lead, for example, to a constant or inconsistent change in the traversing stroke by means of a time program in the control device.
  • the method variant according to claim 11 is particularly advantageous.
  • the actual diameter of the coil is continuously determined, so that the drive is controlled by the control device with the length of the traversing stroke given the current coil diameter.
  • the method according to the invention is independent of the type of winding. Wild winding, precision winding or step precision winding are considered as winding types.
  • the mean value of the traversing speed remains essentially constant during the winding travel.
  • the winding ratio (spindle speed / traversing speed) changes constantly during the winding cycle. With a precision winding, the winding ratio is kept constant. With a step precision winding, on the other hand, the winding ratio is changed in steps according to a predetermined program.
  • the device according to the invention for carrying out the method is distinguished by a high degree of flexibility in the manufacture of the coils. Both the slope angle for biconical coils and the final diameter of the coils can be varied slightly.
  • the control device assumes an instantaneous actual diameter of the coil.
  • the control device is connected to a sensor that detects the speed of the sleeve.
  • One or more lifting functions are stored in a data memory.
  • the winding speed is also stored as a known variable in the control device.
  • the instantaneous bobbin diameter can thus be calculated directly from the speed of the tube and the winding speed.
  • the stroke length which uses a table of values to assign each coil diameter a certain length of the traverse stroke, which is optimized for the process, determines the length of the traverse stroke.
  • the control of the traversing thread driver's drive is controlled with an optimal traversing stroke at all times of the winding travel.
  • the flexibility of the device is further increased by the particularly advantageous development of the invention.
  • the traversing thread guide is driven by means of a motor, in particular a stepping motor. This makes it possible to couple the traversing speed with the respective change in length of the traversing stroke.
  • the traversing stroke can thus be shortened at a constant traversing speed or with a constant amount of thread deposited per time.
  • the coupling between the traversing thread guide and the motor is advantageously designed as a belt drive.
  • the motor has a drive pulley which drives a belt which is guided over at least one pulley.
  • the traversing thread guide is attached to the belt and is moved back and forth within the bobbin width.
  • the sleeve or the spool is advantageously driven by a drive roller resting on the circumference of the sleeve or the spool.
  • the sleeve is clamped on a spool holder between two centering plates, the sensor for sensing the speed of the sleeve being arranged on the spool holder.

Abstract

L'invention concerne un procédé permettant d'enrouler un fil continu, ainsi qu'un dispositif permettant de mettre ledit procédé en oeuvre. A cet effet, le fil est enroulé sur un mandrin entraîné, de manière à former une bobine croisée, le fil étant acheminé en va-et-vient à l'aide d'un guide-fil va-et-vient en un mouvement de translation. Ce mouvement de translation du guide-fil va-et-vient peut être modulé en longueur dans la largeur de la bobine croisée. Pendant l'enroulement (trajet bobine), le mouvement de translation entre une longueur maximale au début du trajet de la bobine et une longueur finale à la fin du trajet de la bobine est modifié selon une fonction de mouvement prédéterminée, de manière à associer une longueur déterminée à chaque mouvement de translation pendant le trajet de la bobine, les longueurs des mouvements de translation étant inférieures aux largeurs des bobines enroulées.
