Definitions

  • the present invention relates to a method for winding a thread on a bobbin, in which the thread reciprocates from a substantially parallel to the bobbin axis drivable thread guide and between the thread guide and the storage point a free piece of thread, the so-called drag length, is formed on the bobbin, and with which the length of the stroke of the thread guide and the thread deposit are variable.
  • the invention is intended to provide a method and a device by which compensates for the shortening of the stroke and compensates for it in a suitable manner or can be used deliberately in the production of coils.
  • the object is achieved according to the invention in that one or more the parameters winding speed, thread laying speed, thread guide acceleration, Thread guide deceleration and distance between thread guide and bobbin shorten the stroke calculated on the bobbin and for precise positioning of the thread on the bobbin is used.
  • the main advantage of the method according to the invention is that it is an exact position
  • the thread can be deposited on the sleeve without the drag length or the thread laying speed need to be reduced. This avoids the risk of Damage to the bobbin and / or the thread guide and receives a greater scope for the arrangement of the mechanical parts.
  • a backup roller which is known to be associated with a striking change in the tow length over the winding cycle is. This saving is possible because the method of the invention Calculation of the stroke shortening from the parameters mentioned, of course, fluctuations the drag length is taken into account and compensated.
  • the omission of the backup roller is particularly important in the manufacture of so-called kingspools are spools on cores with one-sided, strange flange, very advantageous, because then an essential Shorter thread guides can be used, which affects the life of the drive and has a positive effect on the laying speed.
  • the distance between Sleeve and laying unit are not adapted to the respective sleeve diameter become.
  • a first preferred embodiment of the method according to the invention is characterized in that that the winding speed and / or the thread laying speed can be regulated so that a predetermined value or predetermined Stroke reduction values result or will result.
  • a second preferred embodiment of the method according to the invention is characterized in that that the winding speed and / or the thread laying speed and / or the stroke of the thread guide are controlled so that any rotationally symmetrical coils can be built up.
  • a third preferred embodiment of the method according to the invention is characterized in that that cylindrical, biconical or conical coils without using a Back-up roller are manufactured.
  • Another preferred embodiment of the method according to the invention is characterized in that that kingspools or flange coils are manufactured without using a backup roller become.
  • the invention further relates to a device for winding a thread onto a bobbin a thread guide which can be driven back and forth essentially parallel to the bobbin axis and with an electronic control, in particular the length of the stroke of the thread guide and the thread tray are freely variable.
  • control unit Contains an algorithm with which one or more of the parameters winding speed, Thread laying speed, thread guide acceleration, thread guide deceleration and Distance between thread guide and bobbin the stroke shortening on the bobbin can be calculated and can be used for precise positioning of the thread on the bobbin.
  • any coils can be produced without backup rolls are, in addition to the already mentioned Kingspools, for example cylindrical, biconical and conical coils, rotationally symmetrical coils of any shape, on sleeves with one-sided cone or double-sided cones or with shoulders, and it can be used with step precision winding occurring stroke changes in the speed jumps are compensated.
  • the algorithm can also be used for other winding laws such as wild winding, precision winding and parallel windings become.
  • a first preferred embodiment is characterized in that from the parameters Thread guide speed, thread guide acceleration, thread guide deceleration and stroke length the path guide of the thread guide is calculated.
  • a second preferred embodiment of the device according to the invention is characterized in that by means of the path guide of the thread guide and the parameters starting position of the thread, distance between thread guide and bobbin, tube diameter and winding speed the depositing point of the thread on the bobbin is calculated.
  • the winding unit shown in FIGS. 1 and 2 consists essentially of one from a motor 1 drivable spindle 2 for receiving and holding a coil sleeve 3, on one Coil 4, for example a cheese, is wound up, and from a device 5 for laying a thread F, which is also not by a delivery unit, not shown shown spool withdrawn and the thread laying by an inlet thread guide 6 5 is supplied.
  • the coil 4 can along a surface line on a freely rotatable roller (not shown) rest, which is mounted on a suitable carrier part of the winding machine. If such a roller is used, it is by no means necessary for it to be like the back-up roll in known winding devices between the thread laying 5 and the bobbin 4 is arranged.
  • the thread laying 5, which is used to produce the desired winding contains the most important Element a driven by a motor 7 thread guide 8, which is essentially executes a reciprocating oscillating movement parallel to the axis of the coil 4.
  • winding units of this type are, for example, in EP-A-0 453 622, EP-A-0 829 444 and EP-A-0 829 444, to which reference is hereby expressly made.
  • the spindle motor 1 and the thread guide motor 7 are with a programmable controller 9 connected, softer, among other things, the speeds of the two motors 1 and 7 and signals a sensor for the position of the thread guide 8 are supplied.
  • the controller 9 also contains the basic programs for the usual winding laws (wild winding, precision winding, Step precision winding, conical windings with corresponding speed profiles) and certain parameters. In the controller 9, the paths, speeds and accelerations for the thread guide motor 7 and the speed for the bobbin motor 1 calculated on the basis of the applicable winding laws and the motors 1 and 7 are controlled accordingly.
  • the control also contains an algorithm with which one or more the parameters bobbin speed, thread laying speed, thread guide acceleration, Thread guide delay and distance between thread guide and bobbin relative to Stroke of the thread guide resulting shortening stroke calculated on the bobbin and for a precise position Storage of the thread F on the bobbin 4 is used.
  • the latter means that some of the parameters mentioned, for example the thread laying speed and / or the Spool speed can be varied so that the mentioned stroke shortening a certain reproducible value, which value should of course also be zero can.
  • the drag length algorithm first calculates from the parameters yarn feed speed, Thread guide acceleration, thread guide deceleration and from the stroke length, which in principle the length of the bobbin 4 should be the same, the path curve of the thread guide 8. From the acceleration and delay times are those of the thread guide during the acceleration, Deceleration and constant driving phase covered distances and from these the stroke time and the path curve are calculated.
  • the formula for calculating the drop point is a first order differential equation, which is preferably numerical, namely with the classical one Runga-Kutta procedure of the 4th order is solved.
