Definitions

  • the invention relates to a winding machine according to the preamble of claim 1.
  • This winding machine is known from EP-A-5664.
  • a folding device designed as sheet metal is provided, which is guided between the full and the empty winding spindle and which deflects the thread in such a way that the thread wraps strongly around the empty winding spindle.
  • the known winding machine is used for the lossless winding of a continuously occurring thread.
  • US-A-3,913,852 describes the so-called reverse thread catching in contrast to the previously described synchronous thread catching.
  • the thread running towards the full bobbin is also lifted out of the traversing device and pulled out into a loop by a folding device, the thread center, which runs towards the folding device, being guided in the catching plane of the catch slot of the empty tube and having a direction of movement there Touching the direction of movement of the empty tube is opposite, while the thread center running away from the folding device is guided onto the full spool and wound up into a bead.
  • the very strong deflection of the thread in the folding device there is a very strong drop in tension in the thread center running towards the folding device and the empty spindle.
  • the object of the invention is to design the winding machine according to the preamble of claim 1 in such a way that synchronized catching is made possible with a high level of catching safety, and without moving a winding spindle, in order to avoid thread tension changes, particular importance is attached to the fact that the changing process, i.e. folding the thread from the full spool to the empty tube by catching the thread on the empty tube and tearing or cutting off the thread from the full spool takes place in such a short time that the bead formation on the full spool is kept within narrow limits.
  • the invention thus combines the function of the thread guide and the function of the thread braking required for catching in a meaningful manner by making total wrap angles of almost 360 ° possible.
  • the design as a sheet metal prevents the thread or individual filaments of the thread from getting caught.
  • a particular advantage is that the sheet is already moved between the full bobbin and the empty tube at a time when the thread has not yet been torn off or cut off. If the thread is now torn off or severed, the sheet effectively protects the empty tube and the first thread layers formed on it against the thread end protruding from the rotating full spool.
  • the deflection edge is preferably also formed as a boundary edge of a slot arranged in a second sheet, this slot with its open mouth lying in the same normal plane as the holding slot, but obliquely to the traversing direction, so that it extends between the bead plane and the catch plane.
  • the deflection edge can either - as claimed by claim 2 - be immovably connected to the sheet, the deflection edge extending along the holding slot, but with an axial component.
  • the thread is automatically tensioned in the wrap sense and axially between the catching plane and the bead plane when the folding device is moved into the thread run.
  • the solution is provided according to claim 3.
  • the deflection processes take place in the circumferential direction on the one hand and in the axial direction on the other hand, not synchronously, but one after the other, in that the folding device is first moved into its engagement position and then the deflection edge is displaced axially parallel.
  • the folding device according to this invention is suitable not only for synchronous catching, but also for counter-rotating catching in the reverse direction of rotation of the coil turret if the path of the folding device is laid in the manner specified in claim 4. This is preferably done according to claim 5. Claim 6 ensures that the folding device can be adapted to the geometrical conditions of the thread running, which are different in the case of synchronous catching and counter-rotating catching.
  • the configuration according to claim 7 ensures that the folding device does not hinder the winding of very thick coils even under unfavorable geometric conditions.
  • the guide roller is movably mounted with a component that is radial to the operating position and lies movably on the bobbin that is being formed during winding.
  • the guide roller can be raised during the spool change, so that a gap is created between the full spool and the guide roller, which enables the movement of the full spool and the empty spindle.
  • FIG. 7 Another embodiment is shown in side view in FIG. 7.
  • Fig. 8 shows the necessary redesign of the winding machine for reverse rotation.
  • the thread 3 is supplied by the delivery mechanism 17 without interruption at a constant speed.
  • the thread is first passed through the head thread guide 1, which forms the tip of the traversing triangle.
  • the thread with direction of movement 2 then arrives at the traversing device 4, which will be described later.
  • Behind the traversing device the thread on the guide roller 11 is deflected by more than 90 ° and then wound on the bobbin 6.
  • the function of the guide roller is described for example in DE-A-35 13 796.
  • the drive motor required for this can be a synchronous motor which is driven in the phases of the coil change. This motor is not shown here in order to maintain the clarity of the drawing.
  • the guide roller also serves as a "print roll" for guiding the thread onto the bobbin.
  • the guide roller also serves to measure the peripheral speed of the surface of the spool and to control the speed of the drive motors for the spindles when the spindles are driven directly by coaxial motors. For this purpose, reference is made, for example, to DE-C-34 25 064.
  • the guide roller can also be constantly driven and serve as a drive roller 11 for driving the coil 6, as described below.
  • the coil 6 is formed on the winding tube 10.1.
  • the winding tube 10.1 is clamped on the rotatable spindle 5.1 (operating spindle).
  • the coil 6 is driven on its circumference by the drive roller 11.
  • the drive roller 11 is in turn driven by the coil drive motor 20.
  • the winding spindle 5.1 is in the operating position with the winding tube 10.1 spanned thereon and the full spool 6 formed thereon.
  • a second winding spindle 5.2 with a winding tube (empty tube) 10.2 stretched thereon is in the waiting position.
  • Both winding spindles 5.1 and 5.2 are freely rotatably mounted in a rotatable turret 18.
  • the bobbin turret 18 is rotatably mounted in the frame of the winding machine and is pivoted by the drive motor (turret motor 33), so that the spindles 5.1 and 5.2 can be moved alternately into the operating position or waiting position when the bobbin 6 is fully wound on one of the spindles .
  • the traversing device 4 and the drive roller 11 are mounted on a carriage 54, which is only indicated in the drawing.
  • the carriage 54 can be moved in the vertical direction, so that the traversing device and the drive roller can avoid the growing spool diameter of the operating spindle in the operating position.
  • the device for moving the traversing device and contact roller is indicated in the drawing by a cylinder-piston unit 21.
  • the cylinder-piston unit can be acted upon pneumatically. As a result, the weight of the carriage 54 can be fully or partially compensated with the traversing device 4 and the contact roller 11.
  • the cylinder-piston unit 21 can be acted upon pneumatically in such a way that the carriage moves up and there is no gap between the drive roller 11 and the full reel 6. This prevents the movement of the full spool 6 and the empty spindle 5.2 during the spool change and the rotation of the spool turret 18 from being impeded.
  • the carriage is lowered again until the guide roller 11 rests on the empty spindle or the bobbin formed on it.
  • the traversing device is a so-called wing traversing. It has two rotors 12 and 13 which are connected to one another by a gear 22 and are driven by the motor 14. Wings 7 and 8 are fastened to the rotors 12 and 13, as can be seen in particular from FIGS. 2 and 3.
  • the rotors rotate in different directions of rotation 27, 28 and in doing so guide the thread 3 along a guide ruler 9, one wing taking over the guidance in one direction and then immersing under the guide ruler 9, while the other wing guiding in the other Direction takes over and then dips under the guideline 9.
  • the coils are driven by the guide roller 11 at a constant peripheral speed.
  • the guide roller 11 is connected to the coil drive motor 20.
  • the coil drive motor 20 is driven by frequency generator 16 at a constant speed.
  • the traversing motor 14 is driven by frequency generator 15 at a constant speed.
  • the frequency generator 15 can be controlled by the control device 23 as a function of the signals from a program generator 19.
  • the spindles 5.1 and 5.2 can be driven by starter motors 29.1 and 29.2.
  • the starter motors 29.1 and 29.2 are fastened to the turret 18 in alignment with the spindles 5.1 and 5.2.
  • the starter motors are supplied with three-phase current of controllable frequency by the frequency transmitters 30.1 and 30.2.
  • the frequency transmitters 30.1 and 30.2 are controlled by a reversing device 31 which, after a bobbin changing program, sends the command signals to the respective devices of the winding machine, in particular also to the pressure transducer for actuating the cylinder-piston unit 21 (FIGS. 1A and 1B ).
  • the operating state of the winding spindle 5.1 is shown.
  • the coil 6 is almost full.
  • the lifting device 25 and the thread folding device 26 are still in their rest position (FIG. 3A).
  • the bobbin change follows.
  • the following description of the bobbin change also applies to all of the exemplary embodiments.
  • the control unit 31 controls the frequency transmitter 30.2, which supplies the starter motor 29.2 with three-phase current, in such a way that the empty sleeve 10.2 clamped on the spindle 5.2 is driven at the same peripheral speed which also has the contact roller 11.
  • the starter motor 29.1 of the operating spindle 5.1 is put into operation by controlling the frequency transmitter 30.1 at a speed which corresponds to the current speed of the operating spindle 5.1 given the coil diameter of the coil 6 which has meanwhile grown.
  • the turret 18 is rotated in the arrow direction 32 shown in each case by actuating the turret motor 33.
  • the cylinder-piston unit 21 is acted upon with such high pressure that the slide 54 travels upwards with the traversing device 4 and the contact roller 11 and the peripheral contact between the full coil 6 and the contact roller 11 is released.
  • the coil turret 18 is now pivoted so far that the empty spindle 5.2 comes into its operating position and the operating spindle 5.1 into the waiting position, as shown in FIGS. 1B, 4, 7, 8. It should be noted that there is still no contact with the drive roller 11. When moving into its operating position, the empty spindle 5.2 with the winding tube 10.2 clamped thereon is moved into the thread path stretched between the contact roller 11 and the full bobbin 6. It should be noted that the thread 3 is still guided back and forth by the traversing device 4 and is therefore laid on the full spool 6 over at least approximately the entire traversing stroke H.

  • the thread 3 - as shown in FIG. 1B - is brought so far out of the engagement area of the wings 7, 8 of the traversing device 4 that the contact is completely lost. Therefore, the thread slides on one of the inclined sliding edges 35 and reaches the guide notch 36.
  • the guide notch 36 initially lies in a normal plane of the winding spindle, which lies within the traverse stroke 4.
  • the lifting device can be moved on its pivot axis 34 in the direction of arrow 45 (FIGS. 2, 3A) until the guide notch 36 lies in a normal plane in which each coil sleeve 10.1 or 10.2 has a catch slot 37.1 or 37.2. This normal level is referred to as the capture level in this application.
  • the catch slot is a narrow notch made in the surface of the coil sleeve, which extends in a normal plane over part or all of the circumference and which can have a special design, which will be dealt with later. It should be mentioned that the catch slot 37 lies outside the traversing stroke H, in which the winding tube is normally wound.

  • the mouth of the incision 44 on the front of the sheet 40 lies in the same normal plane as the mouth of the holding slot 43. However, the end of the incision 44 lies in the normal plane, in which there is the catch slot 37.2 of the empty sleeve 10.2. This level is referred to as the catch level in this application.
  • the lifting device 25 is now displaced in the direction of the end of the winding tube on which the catch slot 37 is located, ie in the direction of the arrow 45, until the guide notch 36 lies in the normal plane in which the catch slot 37 is also located on the empty tube 10.2 (catch level). .

Therefore, the thread running in the catch slot 37 of the empty spindle 5.2 is now caught by the catch slot. If the thread is of low titre, the thread breaks. Otherwise, a thread cutter consisting of the anvil 46 and the knife 47 can also be actuated at this moment.

       lors du déplacement du bord de glissement (42) vers la position active, le fil (3) tombe dans la fente de retenue (43) et est retenu dans le plan du bourrelet par sa partie arrivant à la bobine pleine (6),
       caractérisé par un bord de déviation (44, 49) qui est disposé sur le trajet du fil, à faible distance de la fente de retenue (43), est solidaire de la tôle (39) et tend le fil (3) parallèlement à l'axe entre le noyau vide (10.2) et la fente de retenue (43) jusque dans le plan de cueillage.
  2. Bobineuse selon la revendication 1, caractérisée par le fait que le bord de déviation (44, 49) est fixe par rapport à la tôle (39) et que le bord de déviation (44, 49) est sensiblement parallèle au plan de la tôle (39) et s'étend le long de la fente de retenue (43) de manière telle que le bord de déviation (44, 49) et la fente de retenue (43) soient situés dans le même plan normal dans la région de l'entrée du bord de glissement (42), c'est-à-dire dans le plan du bourrelet, et que le bord de déviation (44, 49) s'étende de là jusque dans le plan de cueillage.
  3. Bobineuse selon la revendication 1, caractérisée par le fait que le bord de déviation (49) peut être déplacé sur la tôle (39) sensiblement parallèlement à la course de va-et-vient (H) entre le plan du bourrelet et le plan de cueillage.
  4. Bobineuse selon l'une des revendications précédentes, caractérisée par le fait que, indépendamment de la rotation du mécanisme revolver (18) et par rapport au plan axial commun à l'axe du cylindre et à l'axe du revolver, la trajectoire du dispositif de renversement (26) est située du côté où est dirigé le fil (3) venant du cylindre de guidage (11).
  5. Bobineuse selon l'une des revendications précédentes, caractérisée par le fait que la tôle (39) est fixée à l'extrémité libre d'un levier pivotant (41), perpendiculairement à et en porte-à-faux par rapport à celui-ci, que le levier pivotant (41) pivote autour d'un axe (38) parallèle au dispositif de va-et-vient, que l'axe de pivotement (38) est situé du côté du cylindre de guidage (11) vers lequel le fil (3) venant du cylindre de guidage (11) est dirigé, que la tôle (39) et son bord de glissement (42) peut être amenée sur la trajectoire du fil entre l'axe vide (5.2) amené en position de fonctionnement et l'axe en service (5.1) amené en position d'attente.
  6. Bobineuse selon la revendication 5, caractérisé par le fait que la tôle (39) est fixée de manière interchangeable sur le levier pivotant (41).
  7. Bobineuse selon l'une des revendications 5 à 6, caractérisée par le fait que la tôle (39) est montée pivotante sur le levier pivotant (41) et est commandée en synchronisme avec le déplacement du levier pivotant (41) de manière telle que celle-ci forme un angle inférieur à 45° avec la direction du levier pivotant (41) lorsque celui-ci est en position de repos (figure 7).
  8. Bobineuse selon l'une des revendications précédentes, caractérisée par le fait que le cylindre de guidage (11) peut se déplacer par rapport au mécanisme revolver (18) avec une composante radiale par rapport à la bobine (6) et que, pour le changement de bobine, on déplace le cylindre de guidage (11) de manière à obtenir une fente supplémentaire entre le cylindre de guidage (11) et la bobine (6) en position de fonctionnement ou le noyau vide (10.1).
