Definitions
- the invention relates to a method and a winding machine for winding a continuously tapered thread on a sleeve to form a coil, having the features specified in the preambles of the independent claims.
- it is important to wind the thread on each sleeve to form a fixing winding, if necessary.
- a reserve winding, and ultimately the coil as gently as possible.
- a fixing winding is understood to mean a bead-like winding of the thread on the sleeve, in which the thread layers overlap one another in a narrow axial region of the sleeve, either at a distance from the coil, ie outside the laying width, or in the region of the coil or laying width be wound to fix the beginning of the thread on the sleeve.
- a reserve winding is understood to be a winding of the thread on the sleeve, which bridges the distance between a fixing winding arranged outside the coil width and the coil and in which the thread is wound in a thread-like manner onto the sleeve. When the fixing winding is positioned within the coil width, there is no reserve winding.
- the device is a continuous winder with at least two each driven winding spindles on the sleeves of the thread is wound alternately.
- the thread is severed so that the end of the preceding thread thus formed is still wound on the circumference of the full bobbin, while the thus formed new beginning of the thread is detected by a capture area of the empty shell and anchored there, and then the winding takes place on this new sleeve.
- the severing of the thread can be done in any manner, for example by tearing due to increased thread tension or with a cutting device.
- the invention is also independent of the manner of forming the capture area. Of the Capture area can be realized on the respective sleeve, z. B. within the coil width, but often outside the coil width.
- the catching area can be made, for example, as one or more incisions arranged distributed over the circumference of the sleeve, or else by arranging a hooked strip strip or the like.
- the catching area can also be realized on a catching device, which is part of the winding spindle and thus independent of the sleeve.
- a method and a winding machine of the type described is known from DE 197 43 278 C2.
- the continuously tapered thread is wound on a sleeve into a coil by the sleeve is fixed on a driven winding spindle and the thread via a stationary head thread guide, a traversing device with a particular reciprocally driven traversing yarn guide and a contact roller on the sleeve and the spool is laid to form a fixing winding, a reserve winding and the coil.
- Sleeves are used, which are equipped with a catch area.
- two more yarn guide are provided which are mounted on a pivot arm which is mounted in the gap between the coil and an empty sleeve swivel.
- the first thread guide is movable in the winding spindle direction and serves to position the thread relative to the catching area of the empty tube.
- the second yarn guide directs the end of the yarn running onto the full bobbin.
- the traversing device, the contact roller, the winding spindle and the two yarn guides are provided on one side of the thread in such mutual relative position that the thread is guided by the swiveling arm carrying the yarn guide into the gap both from the surface of the empty sleeve as well as released from the traversing device, while the thread is applied during the return pivoting of the pivot arm using the head thread guide and the first thread guide to the capture area of the empty shell enlarging the wrap angle.
- the two yarn guides and the associated drives a considerable machine effort is required.
- a movably controlled thread holder is used to secure the thread in the charging yarn guide and only specifically let emerge from this.
- the yarn is deflected twice in approximately right angles, which can lead to damage to the thread, especially if it is sensitive Spulgut.
- the position and the wound thread length of the fixing winding and the reserve winding are fixed and are therefore not variable. They depend on the geometry of the sleeves used, in particular on the arrangement of the catching area on the sleeve.
- a device for winding a thread on a sleeve to a bobbin in which the thread during the winding cycle with a traversing yarn guide over the length of the traverse stroke is led back and forth.
- This device also has, in addition to the traversing yarn guide a traversable in traversing yarn guide, which allows the acquisition of the yarn in a certain range of the traverse stroke to form a winding outside of the traversing stroke.
- the winding can be formed at the beginning or at the end of the winding cycle.
- winders that work with even three yarn guides, which basically increases the cost of training and the drive of these three yarn guides.
- Such a winder is known for example from DE 29 07 848 C2.
- the first thread guide is also provided here in the region of the traversing device and serves to lift the thread out of the traversing device and to position it relative to the trapping region of the empty tube.
- the second and the third yarn guide are even provided in duplicate and mounted on a turntable, respectively in the sectors between the two winding spindles.
- the second thread guide also serves here to apply the end of the running thread on the full bobbin, while the third thread guide cooperates with the first thread guide, in such a way that the thread between these two thread guides perpendicular to the winding spindle direction and thus relative to the capture area of empty sleeve is positioned.
- the catching area is formed by an incision provided perpendicular to the winding spindle direction on the circumference of the empty shell. The formation of the catch area in another way is not possible. The disadvantages described above occur here increasingly.
- the US 4,298,171 shows a winder with a turntable and two winding spindles arranged thereon.
- the winding spindles are used to hold the sleeves and are in Spulspindelutter, ie in the direction of the axes of the winding spindles, movable to temporarily couple the respective winding spindle with the sleeve sitting thereon with a drive which accelerates the winding spindle to the speed of the contact roller, which then takes over the further drive of the winding spindle on the winding cycle.
- DE 26 43 421 shows a method and a device for winding a continuously tapered thread on a sleeve to form a coil. It is used within the traversing a Kehrgewindewelle whose spatial position is axially changed by means of a cylinder by a fixed stroke in Spulspindelraum.
- the Kehrgewindewelle is with a in its speed controllable and reversible motor driven in its direction of rotation.
- the Kehrgewindewelle has in addition to the normal laying a stepless groove portion into which the traversing thread guide enters by reversing the direction of rotation of the Kehrgewindewelle.
- a switch in the pitchless groove portion allows the traversing yarn guide in conjunction with a new direction of rotation reversal to reach the laying groove for the purpose of building the coil on the sleeve. It sleeves are used, which have a catching area.
- the speed of the Kehrgewindewelle is initially reduced to one for the formation of a fixing winding - there called thread reserve - favorable value and the thread at this reduced speed on the full bobbin further wound.
- thread reserve - favorable value the thread at this reduced speed on the full bobbin further wound.
- a start-of-take detector is actuated in order to bring the reverse-thread shaft into its starting position.
- a timer for switching a control device to a forward rotation state is turned on.
- the disadvantage here is that the method of the traversing thread guide in the stepless groove section a reversal of direction must be done. The drive of the Kehrgewindewelle must therefore be a reversible motor.
- Another disadvantage is that only sleeves can be used with catching range and with fixed geometric dimensions. A flexible adaptation to sleeves with different dimensions is not possible.
- the formation of the layers of the fixing winding and the reserve winding are constant. The formation of the thread lengths of the fixing winding and the reserve winding are randomly dependent on the time at which the traversing yarn guide leaves the pitchless groove portion.
- the pitchless groove portion of this winder can be arranged only outside the laying width of the endless Kehrgewindenut. This means that the fixing winding of the thread can only be arranged at one end region of the sleeve outside the laying width or very large axial displacement paths are required for the traversing device, if the fixing winding, e.g. should be arranged in the middle of the laying width.
- the invention has for its object to provide a method and a winder and the type described in which position and thread length of the fixing winding or a fixing winding with subsequent reserve winding are variably preselected, namely when using sleeves with and without catching range.
- the method of the type described above is characterized according to the invention in that the once detected spatial position of the driven traversing yarn guide of the traversing device is stored and used as a reference position in the formation of the fixing winding and the spool, and that spatial positions at which the traversing yarn guide of the traversing over the winding cycle is just found and tuned to the winding speed.
- the traversing device is traversed in the winding spindle direction with the traversing yarn guide, thereby controlling the axial movement of the traversing device in relation to the spatial positions of the traversing yarn guide of the traversing device over the winding cycle such that on the sleeve successively the fixing winding, the reserve winding and the coil are determined and formed according to position and thread length.
- the method requires first of all to know at an arbitrary point in time where the traversing yarn guide of the traversing device is located. This arbitrary time can be selected anew for each winding cycle. But it is also possible to select the arbitrary time after switching on the main switch of the winder under application of the control voltage once and assign a sequence of Spulticianen or Spulreisen. At this arbitrary time, the spatial position of the driven traversing thread guide of the traversing device is detected once. This signal is determined by location and time, is stored and used as a reference position in the formation of the fixing winding, if necessary. Also the reserve winding, and the coil, so over the entire winding cycle.
- the spatial positions of the traversing yarn guide are determined in their time course over the winding cycle, so that it is known at any time, where is currently the traversing yarn guide. From the knowledge of these spatial positions out, it is then possible, especially at reduced speed of the Kehrgewindewelle targeted to approach individual selected positions in order to take in relation to the drive of the winding spindle or the peripheral speed of the straight wound thread on the sleeve, the various measures , For example, a fixing winding, if necessary. A subsequent reserve winding, and to form a coil, in which each of the local position and the thread length are set repeatable.
- the new method has a number of advantages.
- the fixing winding, if necessary with subsequent reserve winding, and the bobbin can be reproduced reproducibly according to layers and thread lengths according to the wishes of the user precisely defined and adhered to. It may be important to hold by the bobbin exchange impaired Spulgut with certainty in the fixing winding to form the reserve winding z: B. from unchanged Spulgut, as well as the coil.
- the arrangement and the corresponding mechanical effort for the drive of a second and third yarn guide from the prior art, which come into contact with the yarn during the bobbin change, is superfluous. Due to the extent reduced number of parts for the thread transfer also results in fewer points of friction for the Spulgut. The Spulgut is deflected gentler.
- the speed of the Kehrgewindewelle can be regulated or braked to at least approximately zero, that the traversing yarn assumes the selected relative position to the laying width of the winding spindle.
- This can be used with laying groove trained in the usual way Kehrgewindewellen.
- the additional arrangement of an unpolluted groove portion and a switch is basically unnecessary.
- the traversing yarn guide is exactly at the selected location within the laying width, and it is only dependent on the time, with which thread length the fixing winding is applied location accurate.
- the laying channel in the counter-rotating shaft has deflections which have a comparatively small pitch, these areas can also be used without accurate attainment of the rotational speed 0, at least for fixing windings of short thread length. If the fixing winding is not to be mounted within the laying width or in one of the two end regions of the bobbin, but outside the laying width or the bobbin width, which is predominantly the case, the axial displacement of the traversing device in the winding spindle direction is required. This shift is made variably adjustable or controllable, so that the exact position of the fixing winding relative to the coil can be selected on the sleeve and thus different for winding different coils can be specified. It also eliminates the need to use a reversible motor for driving the Kehrgewindewelle.
- Any spatial position of the driven traversing yarn guide of the traversing device can be detected with a first sensor, stored and used as a reference position in the formation of the fixing winding, if necessary.
- the reserve winding, and the coil This determines the beginning of a control process and thus the winding travel.
- a first sensor can be activated at any time. The sensor monitors and detects the path of the driven traversing yarn guide. He sets simultaneously with the determination of a spatial position of the traversing yarn guide the beginning of a time and thus forms a reference position in order to relate to it during the winding cycle again and again to make a statement where the traversing yarn guide is currently located during the winding cycle.
- the rotational speed of the counter-twisting shaft can advantageously be detected continuously in time with a second sensor.
- precision winding it is known to change the winding ratio over the winding cycle and thus the speed of the counter-twisting shaft.
- By detecting the change in the counterbore shaft can be accurately determined, in relation to the reference position, at which point at which time the traversing thread guide is relative to the winding spindle. You can also do without the second sensor. It is then possible to repeatedly use the first sensor and to close its signals with known geometry of the laying channel on the spatial position of the traversing yarn guide over a double stroke. This becomes particularly simple if the speed of the counter-clockwise shaft between two signals is kept constant.
- subsequent reserve winding, and the coil in particular according to the method of claim 1 or 2, is initially customary per se. It is characterized according to the invention in that the signal of the first sensor or a corresponding element of the once detected spatial position of the driven Traversing yarn guide the traversing device of the control device fed there stored in time allocation and as a reference position in the formation of the fixing winding, if necessary.
- a controllable drive is provided for the temporally regulated method of the traversing device with the traversing thread guide in the winding spindle direction.
- the control device is designed so that the axial movement of the traversing device is controlled in relation to the spatial positions of the traversing thread guide of the traversing over the winding cycle so that on the sleeve successively the fixing winding, the reserve winding and the coil are determined and formed according to location and thread length ,
- a first sensor or a corresponding element which is usually arranged in or on the housing of the traversing device, so as to monitor the stroke of the traversing yarn guide and determine at which time the traversing yarn guide passes through a spatial position.
- a signal is formed.
- the time is recorded and the signal is sent to a control device.
- a reference position is set, which is used in the formation of the fixing winding, possibly the reserve winding, and the coil.
- the control device is now designed so that it is able to make a statement about the respective spatial position of the traversing yarn guide relative to the winding spindle in response to this fixed reference position at any time. It is thus not only possible to make a statement as to where the traversing yarn guide is at a particular point in time, but even to predict where the traversing yarn guide will be at a time in the future, albeit adapted to the speed of the counter-shaft.
- the fixing winding may be provided at one end or the other at a distance from the coil to be placed. Often this distance is also desired depending on the application and the type of sleeves used.
- the reserve winding which, although usually fills the distance between the fixing winding and the coil, but in individual cases can be formed separately and in particular with different thread length.
- the traversing yarn guide can be designed for single-thread or multi-thread work. It is important for a reserve winding an additional drive for an axial displacement of the traversing thread guide in Spulspindelraum and its control via a control device that knows or regulates the spatial assignment of the positions of the traversing yarn guide to the sleeve on the winding spindle.
- a second sensor is provided for the continuous detection of the speed of the Kehrgewindewelle over time. Also, this signal of the second sensor is fed to the control device, so that is known in conjunction with the reference position at any time, where the traversing yarn guide is relative to the winding spindle.
- the traversing yarn guide in the direction of the winding spindle must be movable so that the thread between the head thread guide and the catching area of the sleeve is stretched in as straight as possible with little kinked line so that the automatic bobbin change the thread in the capture area of the Empty tube caught. Once this snagging has been detected, the position can be approached in which the fixing winding is to be formed. The fixing winding can also be placed so that the catching area is wrapped.
