Definitions

  • the invention relates to a method for winding thread coulters with a winding machine, in particular for warping and slip creels, in which the individual threads of a thread coulter are monitored for thread breakage by a thread monitor during their winding on a thread monitor, with a thread monitor in the event of a thread breakage Monitoring signal is generated and fed to a control device which stops the winding machine and in which a yarn localization is displayed in the event of a yarn break.
  • the invention is based on the object of improving a method with the features mentioned at the outset so that the control device also enables central localization of the individual thread monitor which gives the monitoring signal.
  • This object is achieved in that the thread monitors are repeatedly queried for the presence of a monitoring signal from the control device when winding up and, in the event of a thread break, a localizing display of the thread break position of the individual thread takes place.
  • the successive interrogation of thread monitors is also suitable for high winding speeds, at which the time for stopping the winding machine when determining the thread breakage may only be very short in order to bring the winding machine to a standstill in time, so that the thread end to be wound up cannot be found in the winding is wrapped up.
  • the method can be carried out in such a way that the display of the individual thread localizing the thread break on the thread monitor he follows.
  • the detection of the thread break is facilitated by the fact that the individual thread monitor is noticeable, for example by an optical and / or acoustic signal. Access to the thread break position of the single thread is very easy.
  • the indication of the individual thread in the case of warping and slip gates, which locates the thread break takes place at the gate output and / or at the control device of the winding machine, where the floor of the gate and a Indicator of the signaling thread monitor are displayed.
  • the indicator of the signaling thread monitor for example a number individualizing the thread monitor or a tag field / individual element identification, the rapid detection of the thread break can be accelerated even further.
  • the method can be significantly improved in that, before the start of winding, a sequential query of predetermined thread monitors or matrix points is carried out by the control device, and that winding is only permitted if the query does not determine a monitoring signal.
  • the predetermination of the thread monitor or matrix points takes place in such a way that the corresponding thread monitor should actually also monitor a thread. Thread monitors which are not predetermined are therefore not included in the monitoring task because this would be superfluous. In this way it can also be determined whether threads have actually been drawn into all predetermined thread monitors. This can be used, for example, to check the gate assembly carried out at a specific point in time.
  • There is a very fast electronic control which in practice means a significant increase in productivity by eliminating control and correction work. Only when this query of all predetermined thread monitors or matrix points, which was carried out before the start of the winding up, showed that there is no monitoring signal, is winding up permitted.
  • the query can also be carried out repeatedly.
  • the query can already be carried out during the assembly of the thread group, if the individual threads are e.g. from the attached coils to the winding tree.
  • Each thread that is pulled in causes the monitoring signal of the associated thread monitor to go out, so that the end of the setup process can be detected and reported. Accidental non-assembly is avoided.
  • the inadvertent winding in the event of incorrect loading by pulling in excess threads can be ruled out by proceeding in such a way that after the query of predetermined thread monitors or matrix points before the start of winding and before the start of winding up, a sequential query of all non-predetermined thread monitors or matrix points is carried out and winding is only carried out is permitted if all the interrogators each have a monitoring signal determined.
  • the method can be carried out in such a way that the query takes place in groups, with several groups being queried simultaneously.
  • a group can be formed, for example, by the winding stations of a gate field.
  • the number of threads forming the winding of the winding machine is also determined when a counter is used. This is decisive for determining the winding tensile force.
  • the method according to the invention can consequently be further developed in that the number of thread monitors or matrix points predetermined before the winding starts is used by the control device to automatically determine the winding tensile force and / or the contact pressure of a pressure roller, taking thread parameters into account before the winding begins.
  • a further automation of the method is achieved, by means of which operating errors are excluded. Incorrect settings of the winding tensile force or those relevant for a tape tension control device Thread tension is not possible. At the same time, the desired winding structure is guaranteed because it depends on the winding tension or the thread tension.
  • winding structure or the winding hardness of a slip tree can also be determined by pressure rollers. Their contact pressure must be varied according to the different thread counts in order to achieve the same winding hardness. This can be done automatically by using the automatically determined number of threads by the computer or by the control device to determine the contact pressure of the contact roller.
  • the method can be carried out in such a way that the localizing display of the thread break position of the single thread that occurs in the event of a thread break, or several such displays, are added up positionally in the course of a winding process or several winding processes and can be called up and retrieved. Therefore, in the course of a winding process or several winding processes, it can be assessed which bobbins have how many thread breaks. This is because the display that occurs in the event of a thread break not only locates the thread and the thread monitor associated with the thread, but of course also the winding point or bobbin assigned to it. If such a bobbin has too many thread breaks, it can be replaced.
  • the yarn quality can be claimed from the yarn supplier. Other causes in the area between the winding unit and the winding of the winding machine can also be detected, e.g. Soiling in the thread clamp area, if this soiling is the cause of thread breakage.
  • the invention also relates to a device for winding thread coulters, with a winding machine, in particular for warping and slip gates, with thread monitors, which each monitor a thread of the thread coulter for thread breakage and provide a monitoring signal in the event of a thread breakage, with a control device which the winding machine switches off when a monitoring signal is present, and with a display device that locates the yarn break.
  • a device for winding thread coulters with a winding machine, in particular for warping and slip gates, with thread monitors, which each monitor a thread of the thread coulter for thread breakage and provide a monitoring signal in the event of a thread breakage, with a control device which the winding machine switches off when a monitoring signal is present, and with a display device that locates the yarn break.
  • the device is thus designed so that the control device can monitor all thread monitors that could be used in relation to the winding machine to monitor the threads of the thread family. Instead, the control device can also interact with a matrix with which the thread monitors are connected. This results in a reduction in the amount of circuitry, also in the control device.
  • the partial programming is carried out in such a way that those memory locations are programmed which are assigned to predetermined thread monitors or matrix points. If the calculator is the thread monitor or a thus intermeshing the matrix connected before winding up the thread sheet or during winding up by querying all thread monitors or matrix points one after the other, the query result can be related to the programmable memory by the comparison device and compared with its storage. If the comparison result matches, this means that all threads are present and monitored at the programmed points. If only a thread monitor or the matrix connected to it or its matrix point emits a monitoring signal, a blocking or switching-off command can be generated for the winding machine. The blocking signal is generated when the winding machine has not yet started up. The winding is then blocked.
  • a shutdown command is generated when the winding machine has started up and there is a need to shutdown due to thread breakage.
  • the device is able to generate a signal that identifies the thread monitor that generated the monitoring signal. As a result, it is possible to easily find the location of the thread break in the area of the device or the gate.
  • the device consists of a winding machine 13 known per se, for example a warping machine or a warping machine.
  • the winding machine 13 winds up a family of threads and thereby produces a winding, the hardness of which is determined by the winding tensile force or the thread tensile forces of the individual threads of the thread family.
  • the winding machine is controlled in a conventional manner in such a way that the threads can only be pulled with a set permissible thread tension.
  • a control device 10 is provided for this control of the winding machine 13.
  • the structure of this control device 10 is known with regard to the control of the winding structure.
  • the control device 10 influences, in a manner not shown, a drive motor of the winding machine and / or a device from which the threads are drawn, which form the thread sheet to be wound up.
  • a device is, for example, a warping or slip gate.
  • Such gates have one A large number of bobbins, which are arranged in rows and rows to hold bobbins, from each of which a thread is drawn. For this purpose, the thread must be guided from the winding point on the outside or inside of the gate to the winding machine. Appropriate deflection and guide elements are available.
  • Each thread is assigned a thread monitor, which can be arranged in a conventional manner, for example at the winding point or at the gate exit.
  • a thread monitor With a thread monitor, the proper guidance of a thread from the winding station to the winding machine can be monitored, because the thread monitor always emits a monitoring signal when the thread is not tensioned or broken. Such a monitoring signal can be used to switch off the winding machine and thus to prevent winding of the thread sheet.
  • an input device 17 which can act on the computer 15 of the control device 10.
  • the input device 17 has an input area 18 with which the memory locations of the memory of the computer 15 can be programmed.
  • the input device 17 has an input area 19 with which further thread-specific parameters can be entered, on the basis of which the computer 15 makes further calculations.
  • the computer 15 has a comparison device, not shown, which is able to check whether the matrix points 12 are occupied with monitoring signals from the associated thread monitors or not. In this case, however, only those matrix points 12 are taken into account by the comparison device for which the corresponding memory locations of the programmable memory were actually also programmed.
  • the comparison is carried out in detail in such a way that the comparison device determines whether a certain matrix point 12, e.g. the matrix point with the code number 1 has the same potential as the programmable memory location with the number 1. If this is the case, switch to the matrix point 12 with the code number 2 etc. until all matrix points 12 to which programmed memory locations correspond have been queried . After such a polling cycle, a further polling cycle can be carried out, or polling cycles are carried out continuously, which can be so shortly one after the other that a quasi-continuous monitoring takes place with respect to the comparatively slow winding of the thread group.
  • the control device 10 or its computer is able to act immediately on the winding machine 13, that is to say to switch it off when it winds up, or to block it before it is given a winding command.
  • the control device is able to act on a display device 14, with which, according to the result of the comparison device, a localized display of the thread break position of the individual thread takes place. So it becomes the number of the thread monitor or the like. displayed so that the operator is immediately able to carry out a targeted check, that is to say to check the thread monitor in question and to make a knot in the event of a thread break or to have it carried out.
  • control device 10 can be used to check the correct formation and arrangement of the thread sheet before the start of winding. Corresponds to the arrangement of the threads with respect If the thread monitor does not follow the pattern that is specified by the programmable memory, a single or repeated successive query of predetermined thread monitors takes place even before the start of winding, if necessary also only non-predetermined thread monitors, the result of which can be used to check the thread arrangement and / or to influence the start of the winding, namely in the sense that winding is blocked if the thread group is not designed as it should be.
  • the number s of programmed memory locations corresponds to the number of threads in the thread family. This number s can be used to let the computer 15 calculate the winding tensile force with which the winding machine 13 may at most pull the thread sheet in order to avoid thread damage. All that is required for this is that the necessary thread parameters, for example dtex number, have been entered using the input area 19 before the calculation is carried out.
  • the dtex number identifies the thread with regard to its resilience and therefore allows easy calculation of the permissible winding tension.
