Definitions
- the invention relates to a device for laying a thread for winding a bobbin according to the preamble of claim 1.
- a device of the generic type for laying a thread is known, for example, from DE 102015 013 380 A1.
- the threads When manufacturing synthetic threads in a melt spinning process or when treating threads in a texturing process, it is common for the threads to be wound into a spool for storage at the end of the process.
- the thread is guided back and forth within a bobbin width, so that a cross winding results to form the bobbin.
- the thread is laid for this purpose in an oscillating manner within the bobbin width, so that cylindrical or biconical cross bobbins are created.
- devices are preferably used in which a thread guide is guided to and fro in an oscillating manner within a laying stroke. It is necessary that at each stroke end of the laying stroke the thread guide has to be braked from a laying speed in order to reverse the direction of movement.
- the thread guide is accelerated to the desired laying speed after braking.
- the thread guide must be braked and accelerated in the reversing areas as quickly as possible in a short time. The shorter the turnaround time, the smaller is a deposited thread mass at the bobbin ends.
- DE 10 2015 013 380 A1 discloses a device in which the thread guide is held on a guide means which is driven in an oscillating manner by a main drive within a laying stroke.
- an auxiliary drive is activated, which is integrated on the guide means and acts on the thread guide.
- an opposite acceleration is generated on the thread guide, so that a quick reversal of the thread guide is possible.
- the control of the auxiliary drive and the control of the main drive are precisely matched to optimize the Umledgebe rich of the thread guide at high laying speeds.
- the guide means has very high inertia forces, which also require a high energy requirement in order to be braked and accelerated.
- auxiliary devices are integrated in the reversal areas, which absorb the kinetic energy at the reversal points and return it to the center L guide for the reversal of movement.
- a device for laying a thread is known for example from DE 3907 125 A1.
- additional auxiliary devices must be integrated at the ends of the laying stroke, which is hardly possible in particular with multi-digit winding systems.
- the object of the invention is to provide a device for laying a thread of the generic type, in which the thread is guided quickly and safely in the reversal areas of the laying stroke at relatively high laying speeds.
- Another object of the invention is to provide a device for laying a thread of the generic type without auxiliary drives or auxiliary devices, which is suitable for relatively high laying speeds.
- the guide means is formed by a belt, that the holder is firmly connected to the belt and that the thread guide is movably connected to the holder in such a way that in a reversal area of the laying stroke between the thread guide and the holder tion a translational relative movement occurs.
- the invention is characterized in that the thread guide in the Ummondbe range is decelerated and accelerated independently of the guide means. In this way, very short reversal times of the yarn guide can be achieved. Due to the mobility of the thread guide on the holder, kinetic energy of the thread guide can be used in the reverse phase in order to implement a short deceleration phase and acceleration phase on the thread guide. While the guide means with the holder is already braked in the reversal area, no braking forces act on the thread guide, so that the thread guide moves relative to the holder and is briefly continued unhindered at the laying speed.
- the development of the invention is seen in which the thread guide and / or the holder are assigned several stops, through which the relative movement between the thread guide and the holder is limited.
- the duration of the mobility of the thread guide relative to the holder is preferably dimensioned in such a way that braking and renewed acceleration of the holder can be achieved by the guide means during the relative movement of the thread guide.
- the development of the invention is preferably carried out in which the thread guide and the holder are connected to one another by a slide guide through which the thread guide can be slid relative to the holder.
- the thread guide can thus be guided in the same direction during the relative movement. The laying of the thread on the circumference of the bobbin remains unaffected.
- the thread guide In order to limit the relative movement of the slide guide, provision is also made for the thread guide to be arranged on the holder by a carrier plate which has an elongated sliding opening to form the stops, the stops of the sliding opening with a pin of the holder Working together.
- the development of the invention has proven itself, in which the thread guide is arranged at a free end of a rocker arm, wherein the opposite end of the rocker arm is held by the pivot bearing on the bracket.
- the rocker arm makes it possible to achieve a sufficient mass that initiates the relative movement when the guide means is braked.
- the rocker arm is pivotable in the direction of movement of the guide means and acts when braking the bracket a continuation of the laying movement for Ver lay the thread.
- the mobility of the rocker arm is limited by the development of the invention be, in which the rocker arm at each end of the laying stroke is assigned to one of the hits, the stops are formed on the bracket.
- the thread guide can be safely guided in the linear areas for laying the thread through the guide means.
- FIG. 1 schematically shows a top view of the first embodiment of the device according to the invention for laying a thread.
- FIG. 2 shows schematically a side view of the embodiment from FIG. 1, 3.1 and
- FIGS. 1 and 2 show different operating situations of the thread guide of the exemplary embodiment from FIGS. 1 and 2
- a first embodiment of the device according to the invention for laying a thread for winding a bobbin is shown schematically in several views.
- Fig. 1 the embodiment is shown in a plan view and in Fig. 2 in a side view.
- Fig. 1 the embodiment is shown in a plan view and in Fig. 2 in a side view.
- the exemplary embodiment has a guide means 1 for laying a thread.
- the guide means 1 is designed as an endless belt 2.
- the endless belt is guided through opposite pulleys 3.1 and 3.2 and a drive wheel 4.
- the drive wheel 4 is connected to a drive motor 5.
- a Fa den vinegar 7 and a bracket 6 is arranged in the portion of the belt 2 between the pulleys 3.1 and 3.2 .
- the holder 6 is firmly connected to the belt 2.
- the thread guide 7 is movably arranged on the holder 7 in such a way that a relative movement between the thread guides 7 and the holder 6 guided by the belt 2 is possible within a laying stroke at the stroke ends.
- the holder 6 has a protruding pin 11 on which the thread guide 7 is guided by a slide guide 8.
- the thread guide 7 is connected to a carrier plate 9 which has a sliding opening 12 oriented in the direction of the belt 2.
- the sliding opening 12 is limited by opposing stops 10.1 and 10.2.
- the carrier plate 9 on the holder 6 can be guided back and forth between the stops 10.1 and 10.2 of the slide guide 12 through the slide guide 8 on the pin 11.
- FIGS. 4.1 and 4.2 Another possible embodiment is shown schematically in FIGS. 4.1 and 4.2.
- the exemplary embodiment according to FIGS. 4.1 and 4.2 is identical to the aforementioned exemplary embodiment with regard to the guide means 1 and only differs in the structural design of the holder 6 and the thread guide 7.
- the holder 7 has a pivot position 13, the pivot axis of which is orthogonal to the belt plane.
- a rocker arm 14 is held on the holder 6 by the pivot bearing 13.
- one end of the rocker arm 14 is held in the pivot bearing 13.
- the rocker arm 14 can be pivoted in the direction of movement of the guide means or the belt 2.
- the relative movement to the holder 6, which is carried out in a translatory manner, is stopped by a stop 10.1 and 10.2 assigned to the reversing areas.
- the stops 10.1 and 10.2 are arranged on the holder 6.
- Fig. 4.1 the situation is shown how the Hal sion 6 with the thread guide 7 are guided together in one direction of movement. In this situation, the rocker arm 14 is in contact with the stop 10.2.
- FIGS. 1 and 2 The embodiment shown in FIGS. 1 and 2 is exemplary in its structure. In principle, it is customary to guide the thread guide or the holder through guide rails within the laying stroke. In addition, it is also possible to change the length of the laying stroke while a coil is being wound. Likewise, several holders and thread guides can also be arranged on a belt in order, for example, to guide the threads of two adjacent winding stations.
