Definitions

  • the invention relates to a precision bobbin with a wire, wire, ribbon or similar thread wound onto a bobbin in precision winding, as well as a method and a device for producing the bobbin.
  • the precision winding is distinguished from the wild winding by the fact that when the thread is wound up, the ratio of the number of turns of the bobbin and the traversing speed of the thread remains constant.
  • the number of double strokes of the thread guide per unit of time is usually used as a measure of the traversing speed of the thread.
  • a double stroke is a back and forth movement of the thread guide along the jacket of the bobbin tube.
  • the ratio of the bobbin speed to the number of double strokes per minute is referred to as the number of turns and represents the number of bobbin revolutions during a to-and-fro movement of the thread guide.
  • bobbin is understood to be a bobbin tube wound with thread.
  • An image winding is called the position of the thread here, in which the reversing loop on the end face of the bobbin lies at an angle above the reversing loop of one of the preceding thread layers.
  • the image winding is located above the immediately preceding thread layer, which leads to instabilities in the bobbin structure and loop formation when the bobbin is unwound.
  • rational decimal numbers are used as the number of turns, so that a large number of intermediate layers of the thread are present between the image winding length and the previous thread layer which coincides with it angularly.
  • the number of turns is therefore made up of an integer part and a decimal fraction, which is referred to as decimal number of turns.
  • the decimal angle determines the position and the distribution of the reverse loops of the thread layers on one end of the bobbin.
  • Precision winding bobbins are usually produced on winding machines in which the rotating bobbin tube and the thread guide are connected to one another by a mechanical gear.
  • the gear ratio of the gearbox can be varied in fine stages in order to be able to set the most favorable number of turns.
  • DE-AS 19 13 451 an electronic control circuit is described, which allows a control of the drive of a drive device for the thread guide in accordance with the rotation of the bobbin. This allows a large number of desired number of turns to be set, so that the number of turns can often be changed even during the coil travel. A change in. The number of turns during the bobbin travel can result from the fact that the winding speed of the thread on the bobbin should be kept as constant as possible. A method suitable for this purpose and the associated device have been described in European patent application with publication number 55 849.
  • the number of turns used in the build-up of the bobbin influences the distribution of the reverse loops of the individual thread layers on the circumference of the bobbin and thus the mass distribution of the thread. In this way, coils with an uneven structure are easily obtained, which is disadvantageous not only when winding up but also when unwinding.
  • the connection between the bobbin rotation and the traversing movement of the thread guide is established via an analog control circuit which permits a slight, albeit slight, deviation in the number of turns. In this way, compared to the wild winding, in which the number of turns changes continuously, a much better coil structure is achieved. However, a coil quality in precision winding with an optimal number of turns cannot be achieved in this way.
  • a good coil build requires, among other things. an even distribution of the thread mass in the bobbin. Otherwise, density differences occur which not only adversely affect the visual appearance of the finished wound bobbin, but also lead to difficulties during winding due to imbalance and out-of-round running of the bobbin tube and, particularly when driving the bobbin, interfere with its circumference due to friction.
  • the invention is therefore based on the object of providing a precision bobbin with optimum properties with regard to the bobbin structure, in particular the mass distribution of the thread on the bobbin, and with regard to the bobbin run; Furthermore, a method for winding the coil at a constant peripheral speed and a device for winding are to be specified.
  • the bobbin according to the invention is characterized in that the fluctuation in the density of the reversing loops of the thread along the circumference of the bobbin on an end face between two successive image windings is less than 8, preferably less than 4, the density being the number of reversing loops per one Section of the scope is.
  • the thread distribution during the build-up of the bobbin is evened out in such a way that even with stepped precision winding, regardless of the type of thread, error-free winding and even unwinding of the bobbin is guaranteed without thread breaks or loop formation.
  • the section is expediently the hundredth part of the coil circumference. If the section is the tenth part of the coil circumference, the variation remains less than 4, preferably less than 2, in a development of the invention.
  • a method for winding a thread or the like onto a bobbin tube which can be driven at a constant bobbin circumferential speed by means of a thread guide which can be moved along the jacket of the bobbin tube in precision winding provides according to the invention that the ratio of the speed of the bobbin tube to the number of double strokes of the thread guide (number of turns) is set in this way is that the variation in the density of the reversing loops " along the circumference of the coil on an end face between two successive image windings remains less than 8, preferably less than 4, the density being the number of reversing loops per section, suitably the hundredth part of the Scope is.
  • decimal ud determines the position of the respective reversing loop in parts of the coil circumference in relation to a coil with a constant radius.
  • the difference The number of decimals ud and therefore the number of reversing loops between the class with the highest number of decimals ud and the least number with decimals ud is termed the span S, which indicates the fluctuation in the occupancy density of the reversing loops of the thread along the circumference of the bobbin represents an end face after passing through the z traversing periods.
  • the span S represents a measure of the uniformity of the distribution of the z reverse loops on the k classes and thus also of the mass distribution of the thread in the bobbin. For the number z, it is advisable to choose a sufficiently large number of double strokes between two successive image windings.
  • the span S may at no time be more than 8, preferably more than 4, or if 10 of the same size are selected Classes, the span S must never be more than 4, preferably more than 2, in order to obtain the desired uniformity of the thread distribution in the bobbin.
  • limit values for the span S that are permissible for a good coil structure depends on the material to be wound, i.e. the properties of the thread. For normal material to be wound, compliance with the upper limit values specified above is sufficient; for sensitive material to be wound, it is recommended that the lower, the above Observe limit values for the span S.
  • the crossing angle of two layers of thread on top of the bobbin is determined and that the number of turns is set such that the crossing angle is kept between a predetermined minimum and a predetermined maximum crossing angle. It is advisable to choose the difference between minimum and maximum crossing angles to a maximum of 10%. Depending on the type of material to be wound, it may be advisable to choose a difference of no more than 5%.
  • the number of double strokes is changed in an angle-synchronous manner to the rotation of the bobbin tube, which can be achieved, for example, by angularly synchronous control of the transmission ratio of the bobbin rotation and the drive device of the thread guide.
  • the gear ratio or the number of turns should be kept very precisely in the mean. A deviation is only permissible in the fifth or better still in the sixth digit of the decimal.
  • the integration time for forming this mean is of minor importance. It can be several seconds if the deviations from the mean are statistically distributed.
  • the time required to change the number of double strokes depends on the size of this change, the mass that has to be accelerated and the available driving force. Adequate security against the direct superimposition of successive thread layers is achieved in a further development of the invention if the transition from a first number of turns to a second number of turns is carried out during less than ten double strokes of the thread guide.

  • the evaluation device can expediently contain a display device which displays the number of occupations of the individual memory areas.
  • a further comparison device for the evaluation device device belongs, which compares the difference in the number of occupancies of the memory areas with a predetermined further barrier signal and safeguards the decimals of the number of turns entered into the multiplier in the constant memory when the barrier corresponds to the further barrier signal.
  • the transmission ratio which represents the ratio of the speed of the shaft to the speed of the bobbin, differs from the reciprocal of the number of turns only by the factor which indicates how many double strokes (number of threads) the thread guide performs per one revolution of the shaft driving it.
  • the signal for the transition from one number of turns to the next can e.g. triggered by reaching a predetermined speed of the bobbin, or by reaching a predetermined minimum speed of the motor for the shaft of the thread guide, by reaching a predetermined diameter of the bobbin, or by reaching a minimum crossing angle.
