Definitions

  • the invention relates to a method for winding a thread spool according to the preamble of claim 1, a device for performing the method according to the preamble of claim 7 and a thread spool.
  • threads are wound into thread spools between the process steps for the purpose of storage.
  • the bobbins wound in a previous process are then presented to the subsequent process as supply bobbins.
  • thread spools of this type have good thread pull-off properties.
  • a method and a device for producing such thread spools is known for example from WO 00/68126.
  • the thread is laid before being deposited on a thread spool within a traversing stroke in such a way that end faces which are as straight as possible are formed at the ends of the spools, so that the thread is pulled off properly.
  • a continuous further processing process is guaranteed until a next thread end. Processing stages of the subsequent processes can thus often be determined by a thread end of a thread spool.
  • the invention has the particular advantage that the entire thread quantity of a thread spool can be divided into several subsets. Each subset can be defined by a thread end created on the thread spool after winding.
  • the thread bobbin is wound in such a way that the thread is guided at least once briefly outside the traversing stroke, by which the bobbin width is determined, before the final diameter of the thread bobbin is reached, so that an end-side thread loop forms on the thread bobbin.
  • the thread is advantageously guided by a controllable guiding means which at least once briefly guides the thread in the predetermined interval in such a way that a portion of the thread is deposited outside the bobbin width.
  • the thread spools according to the invention therefore have the particular advantage that, prior to the further processing process, a plurality of thread ends can be generated, each of which specifies a thread length defined for the subsequent process. For example, it is known that false twist textured and dyed threads are twisted in a film process. In the follow-up process, the twisted threads are wound into thread spools in predetermined thread lengths. In the case, that a "yarn package according to the invention is presented to the twisting process, the twisting process can be by the predetermined on the bobbin subset determined so that, for example, an automatic doffing process for changing the thread bobbins is possible.
  • the bobbin according to the invention are thus particularly suitable for subsequent processes, wherein in a Process step defined thread lengths are to be processed.
  • the thread loop is therefore formed by a piece of thread lying outside the winding assembly of the thread spool, which is preferably dimensioned in length such that a new thread end and a new thread start is formed after the thread loop has been severed.
  • the point in time for the formation of the thread loop can be determined by the winding parameters such that a fraction of the total thread quantity of the thread spool can be determined.
  • a winding time or a diameter of the thread spool or a wound thread length can be specified, which defines a first partial quantity on the thread spool from the beginning of the winding of the thread spool.
  • the specification of winding times is preferably used to determine the partial quantity.
  • the development of the method according to the invention is particularly advantageous, in which the thread is guided by a traversing thread guide to form the thread loop.
  • This variant of the method is preferably used in cases in which the thread is held within a traverse stroke by an oscillating traverse thread guide.
  • the formation of the thread loop can be preferred briefly lead through an additional loop guide, which catches the thread in the thread run between a traversing thread guide and the thread spool.
  • the development of the method according to the invention is particularly suitable, in which the thread loop is produced on the side of the thread spool on which a thread reserve winding associated with the thread spool is wound.
  • all thread ends can be produced on one end face of the thread spool on the thread spool.
  • the guide means is coupled to a control device.
  • the control device has a data input and a data memory for receiving target parameters of the thread spool and a comparator for comparing the target parameters with actual parameters of the thread spool.
  • the parameters of the thread bobbin are the winding time or the specified bobbin diameter or the specified thread length that is used to determine the partial quantity.
  • FIG. 1 shows schematically a first embodiment of the device according to the invention for performing the method according to the invention.
  • FIG. 3 schematically several views of a thread spool according to the invention.
  • Fig. 4 schematically shows another embodiment of the device according to the invention for performing the method according to the invention 1
  • Fig. 1 schematically shows a first exemplary embodiment of a device according to the invention for carrying out the method according to the invention. Only the components of the device that are relevant for carrying out the method according to the invention are shown here.
  • a bobbin tube 2 is held on a bobbin holder 3 and a bobbin 1 is wound around its circumference.
  • the coil holder 3 is shown as a driven spindle 4.
  • the spindle 4 has clamping devices (not shown here) on the circumference in order to fix the winding tube 2 fitted onto the spindle 4.
  • the drive of the spindle 4 is not shown here.
  • the spindle 4 is preceded by a rotatably mounted pressure roller 5 in the thread course.
  • the pressure roller 5 or the spindle 4 are held in a movable manner in order to allow the thread spool 1 to grow while a thread 18 is being wound up.
  • the pressure roller 5 lies against the circumference of the thread bobbin 1 during the winding process.
  • a traversing means 6 is arranged upstream of the pressure roller 5 in the thread path.
  • the traversing means 6 has at least one traversing thread guide 7, which is driven oscillatingly within a traversing stroke by means of a drive means 19.
  • a guide means 8 is arranged laterally next to the thread bobbin 1 in the space between the traversing means 6 and the bobbin holder 3.

  • an incoming thread 18 is continuously wound into a thread spool 1.
  • the thread 18 is through the Traversing thread guide 7 is guided back and forth within a traversing stroke, so that a thread spool 1 with a cross winding is created.
  • the thread spool 1 has a cylindrical shape with the straight end faces 14.1 and 14.2.
  • the filing of the thread 18 takes place via the pressure roller 5 lying on the circumference of the thread spool 1.
  • the spindle 4 is driven to wind up the thread 18 in such a way that the peripheral speed of the thread spool 1 remains constant during the winding process.
  • the speed of the spindle 4 is detected by the sensor 12 and given to the control device 1. Since the spindle speed changes as a function of the increase in the thread bobbin 1, the actual parameters of the thread bobbin, such as winding time, bobbin diameter or thread length, can be derived directly therefrom and further processed in the control device 11.
  • the control device 11 has a comparator 22 which is linked to a data memory 20.

  • the thread spool 1 now has a thread loop formed on the end face 14.1, which the end and the beginning of at least two subsets of the Define thread spool 1. This process can be repeated so that the entire amount of thread taken up by the thread spool can be divided into two, three or four subsets.

  • a thread loop 15 is formed on the end face 14.1.
  • the thread loop 15 consists of a piece of thread that protrudes from the bobbin.
  • the piece of thread extends over part of the circumference of the end face 1.
  • the length of the piece of thread is selected such that a thread end and a thread start can be formed after severing the thread loop 15.
  • the thread loop 15 defines two partial quantities of the thread wound on the thread spool 1, which can be drawn off from the thread spool 1 one after the other in a subsequent process.
  • Each of the partial quantities on the thread spool 1 preferably has the same thread lengths, so that the continuity of the subsequent process is limited by the respective thread ends, so that, for example, an automatic thread change or bobbin change can be carried
  • the thread spool 1 has on the side facing the end face 14.1 on the winding tube 2 a thread reserve winding 13, which marks the start of the winding process of the thread spool 1.
  • the thread reserve winding 13 contains the thread end of the second wound subset on the thread bobbin 1.
