Definitions

  • the invention relates to a winding machine according to the preamble of claim 1 and a method for changing bobbins.
  • the winding machine in which the relative movement between the contact roller and the winding spindle is carried out in accordance with the growing bobbin diameter by rotating a pin, is e.g. known from DE-OS 32 07 375 (Bag. 1241).
  • the contact roller is fixed in the machine frame.
  • the winding spindle is mounted in a rocker which is pivotally mounted on the pin, so that the winding spindle can assume an outer and an inner radial position relative to the pin.
  • This version lacks stability for large bobbin weights and high thread speeds.
  • a winding machine is known in which a winding spindle is mounted in a movable carriage.
  • the contact roller is mounted in a likewise movable carrier.
  • the carriage of the winding spindle is held by pneumatic cylinders which are pressurized depending on the movement of the carrier of the contact roller. This compensates for the weight of the carriage with the winding spindle and bobbin. As the coil diameter increases, the pressure force exerted in the cylinders is reduced in such a way that the carriage sinks due to its own weight. Stick-slip effects are inevitable.
  • the object of the invention is to create a winding machine in which the spindle is supported in a stable and vibration-free manner and can be moved uniformly in a controlled manner, even with high winding weights and winding speeds.
  • the solution replaces the known pivot lever with a so-called extended pin, on which a single winding spindle is mounted eccentrically to the axis of rotation of the pin.
  • the winding spindle is rotatable and can be driven by a coaxial motor if necessary.
  • the motor is also attached to the pin on the rear of the pin.
  • the bearing diameter is increased so that it is larger than the length of the actual pivot lever, i.e. is greater than the distance between the swivel axis and the spindle axis.
  • This solution results in very stable, vibration-free, smooth-running and durable storage. So far, two spindles have already been installed on a turntable, which are alternately put into operation by turning the plate. However, the swivel lever principle or a straight-moving carriage was always used for only one winding spindle if the winding spindle was not arranged in a stationary manner.
  • pivot lever or pin is no longer pivoted by the bearing force on the spool as before, but is forcibly pivoted by a drive motor. Control devices for this result from the following claims.
  • the position of the contact roller remains essentially unchanged in the course of the winding cycle, even as the bobbin diameter increases.
  • the required relative movement, with which the distance between the axis of the contact roller and the axis of the winding spindle is adapted to the growing bobbin diameter, is carried out by rotating the pin during the winding travel.
  • the rotation is effected by a motor.
  • the motor is controlled by a sensor which detects the movement of the contact roller, i.e. especially the path that the carrier of the contact roller executes.
  • the motor of the pin is controlled so that the pin rotates so far, even with very small movements of the contact roller, that the winding spindle dodges with the increasing coil diameter of the contact roller, while the contact roller hardly leaves its starting position and immediately reaches it again.
  • the actuation of the motor assigned to the journal thus takes place as a function of the output signal of the sensor, which detects the deviation between the actual value and the target value of the position of the contact roller.
  • the rotary actuator can be operated step by step.
  • a certain maximum value of the deviation between the actual value and the target value of the position of the contact roller is predefined, for example programmed, to the rotary control device. As long as the deviation is smaller than this predetermined maximum value of the deviation, the rotary drive is braked so that the pin cannot change its rotational position.
  • the brake is released and the pin is rotated at a predetermined speed until the deviation between the target value and the actual value is again below the predetermined maximum value of the deviation.
  • the rotary drive is actuated by the rotary control device and the sensor so that the rotary drive is continuously in operation and the pin rotates continuously in such a way that the deviation between the desired value and the actual value of the position of the contact roller is corrected to a certain, low value becomes.
  • the contact roller and its carrier as well as the winding spindle and the pin with the rotary drive thus form, together with the rotary control device and the sensor, a control circuit by means of which the position of the contact roller is kept essentially unchanged.
  • the center distance between the contact roller and the winding spindle is not dependent on the contact force between the contact roller and the winding spindle, but is determined by a rotary drive which positively increases the pin in the sense of enlarging the Axis distance drives.
  • the winding machine according to this invention is preferably used for winding freshly spun man-made fibers in spinning plants.
  • the pin rotates in the same direction as the spindle.
  • the contact force initially increases. It is therefore wound with a low contact pressure at the start of the winding cycle, thereby avoiding damage to the first thread layers. Furthermore, the change the contact pressure can be kept low.
  • the guide of the contact roller and the pivot point of the pin and the turning circle on which the spindle axis lies (spindle turning circle), as well as the radius of the contact roller relative to each other are designed so that at the desired maximum diameter ratio the change in the contact force of the contact roller on the coil in The course of the winding travel remains within the desired limits.
  • the diameter ratio here means the quotient: diameter of the winding spindle at the start of the winding cycle (empty tube) / diameter of the winding spindle at the end of the winding cycle (full package). This operating diameter ratio is at least 1: 3 in modern winding machines.
  • the permitted change in the radial contact pressure is in any case less than 50%, the contact pressure assuming a lower value, which means that it may initially increase at most.
  • the radial force exerted by the contact roller on the bobbin will change by no more than 10% in the course of the winding cycle in the solution according to claim 4, preferably by no more than 5% after winding the first thread layers.
  • the winding machine according to this invention is operated so that the pin is rotated in the same direction of rotation as the winding spindle as the bobbin diameter increases.
  • the winding spindle is driven by axle drive motors.
  • the relief device can be, for example, a force transmitter for a constant force, for example a spring or a pneumatic or hydraulic cylinder-piston unit, which is acted upon with constant pressure.
  • a loading device e.g. a hydraulic or pneumatic cylinder-piston unit is provided, which acts on the carrier of the contact roller and generates the necessary contact pressure.
  • the loading device can be designed so that it generates a constant contact pressure. However, it is also possible to design the loading device in such a way that the contact pressure is controlled in the course of the winding travel according to a certain programmed course.
  • the carrier on which the contact roller is mounted is preferably a rocker arm which is pivotally mounted on one side in the machine frame and at the other free end of which the contact roller is seated (claim 7). If the contact roller is to rest on the spool with its own weight, the rocker is arranged horizontally or inclined. If the contact roller is to rest on the spool without the influence of its weight, the rocker must be arranged essentially vertically.
  • the suspension in a rubber block also has the advantage that the rubber block not only the pivoting movement within the scope of the slight measuring deflections of the contact roller, but also a movement perpendicular to it, i.e. on the connecting line between the pivot axis and the axis of the contact roller.
  • the contact roller can align not only in the swivel direction, but also perpendicular to it, parallel to the axis of the winding spindle. It is also particularly important that the rubber block dampens the movement of the contact roller.
  • the traversing according to this invention can be one of the traversing devices known from the prior art.
  • the traversing device can be fixed in place in the machine frame.
  • the thread that wraps around the contact roller is deposited on the contact roller with the traversing law of the traversing device, the reversal of stroke depending on the distance between the traversing device and the line of the thread on the contact roller. Any change to this distance is included in the filing law.
  • the embodiment according to claim 11 and 12 or 13 ensures that despite the slight movement of the contact roller the distance between the traversing device and the contact roller does not change in the course of the winding cycle.
  • the traversing device is preferably also mounted on a rocker arm, which is pivotably mounted either coaxially with the rocker arm of the contact roller or on the rocker arm of the contact roller. This makes it possible to lift the traversing device from the contact roller for maintenance, so that on the one hand the contact roller and on the other hand the traversing device is easily accessible.
  • the measure according to claims 9 to 13 prevents the traversing also executing a movement perpendicular to the thread path when it moves relative to the contact roller.
  • a drive device acts on the carrier of the traversing mechanism, by means of which the distance between the contact roller and the traversing mechanism can be changed in the course of the winding cycle.
  • the invention thus also offers the possibility of traveling with a variable traverse stroke during the winding travel.
  • the drive device is controlled according to a predetermined program.
  • Appropriate programming can shorten the stroke in the course of the winding travel, in particular at the beginning of the winding travel (claim 16).
  • the contact roller can perform a slight evasive movement so as not to hinder the empty tube moving into the operating position.
  • the mobility of the contact roller is used, which is used in the context of this invention to control or regulate the rotary drive of the pin in the course of the winding cycle as a function of the growing coil diameter. However, this function is overridden during the formation of the first thread layers on the empty tube.
  • the pin can also be turned further so that the bobbin is released from the contact roller. In order to move the winding spindle back to the starting position of the operating position after removing the full bobbin and placing the empty tube, the pin can be turned in the same direction or "backwards".
  • the measuring function of the contact roller by means of which the growing bobbin diameter is detected, can be started again after a certain programmed time has elapsed or after the full bobbins have been exchanged for empty tubes on the bobbin spindle, which is at rest, by lowering the contact roller and making contact is brought with the winding spindle.
  • a special control is unnecessary by the measure according to claim 21.
  • the restart of the measuring function of the contact roller takes place in that there is contact between the coil and the contact roller again with increasing coil diameter and thus a measurement deflection of the carrier of the contact roller.
  • the contact roller is driven during the non-contact time, preferably driven at a peripheral speed which essentially corresponds to the target peripheral speed of the coil.
  • a suitable drive for this can be seen from DE-A 38 34 032.
  • the winding machine shown is supplied with the thread 3 by the delivery unit 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 contact roller 11 is deflected at more than 90 ° and then wound on the spool 6.
  • the coil 6 is formed on the winding tube 10.
  • the winding tube 10 is clamped on the freely rotatable spindle 5.
  • the winding spindle 5 is with the clamped thereon Spool tube 10 and the spool to be formed thereon in the beginning of the operating position.
  • the winding spindle 5 is freely rotatably mounted in a rotatable pin 18.
  • the spindle 5 is driven by synchronous motor 29.
  • the synchronous motor 29 is fastened in alignment with the spindle on the pin 18.
  • the synchronous motor is supplied with three-phase current of controllable frequency by frequency generator 30.
  • the frequency transmitter 30 is controlled by a control unit 31, which is controlled by a speed sensor 53.
  • the speed sensor 53 senses the speed of the contact roller.
  • the control unit 31 controls the frequency transmitter 30 of the spindle 5 in such a way that the speed of the contact roller 11 and thus also the surface speed of the coil remains constant despite the increasing coil diameter.
  • the synchronous motor 29 can be replaced by an asynchronous motor.
  • a control signal is superimposed on the control frequencies F4 and F5, so that the setpoint value of the spindle speed, which is predetermined by the control unit 31, is exactly maintained.
  • a suitable controller results from DE-C 34 25 064 (IP-1348).
  • the pin 18 is rotatably mounted in the frame 17 of the winding machine and is pivoted by the drive motor (pin motor 33).
  • the storage occurs in that 8 suitable roller bearings, here ball bearings 20 as an example, are attached to the circumference 19 of the pin.
  • This type of storage ensures precise concentricity, smooth running and durability. It is therefore particularly ensured that the spindle axis is always parallel to the axis of the contact roller.
  • the journal motor 33 acts on the journal 18 via a central shaft 23.
  • the journal motor 33 serves to rotate the journal in the sense that the center distance between the contact roller 11 and the spindle 5 is increased as the coil diameter increases.
  • the journal motor 33 can be designed as a brake motor.
  • a brake motor has the property that its rotor is immovably locked, i.e. is no longer rotatable if the brake motor is not connected to a power source.
  • Such a journal motor 33 which is designed as a brake motor, is shown schematically in FIG. 10. 10 is a detailed drawing of FIGS. 1, 3, 4 and shows the rotary drive and the rotary control device for the pin 18.
  • the shaft 70 of the pin motor 33 and the pin 18 is acted upon by a brake 71.
  • the brake 71 is actuated by an electromagnet 72.
  • the electromagnet is connected to the rotation control device 54.
  • the rotation control device 54 alternately closes either the rotor circuit of the journal motor 33 or the circuit of the electromagnet 72 of the brake 71 in dependence on the output signal of the sensor 52, which senses the movement of the carrier 48 or 63 for the contact roller.
  • the pin motor 33 can also be a stepper motor which rotates continuously at a very slow speed and which is controlled by the rotary control device in dependence on the output signal of the sensor 52, which senses the movement of the carrier 48 or 63 for the contact roller, in such a way that the center distance between the contact roller 11 and the spindle 5 increases continuously with the increasing coil diameter.
  • the contact roller 11 is mounted on a carrier so that the contact roller can move with a radial component to the spindle.
  • the rocker 48 serves as a carrier for the Contact roller.
  • the rocker 48 is mounted in the machine frame so as to be pivotable about the pivot axis 50.
  • the pivot axis 50 is - as already said - so that the contact roller is movable with a radial component to the spindle 5.
  • the pivot axis 50 is formed by a rubber block. This rubber block is firmly clamped in the machine frame.
  • the rocker 48 is attached to the rubber block, so that the rocker 48 can be pivoted elastically. An embodiment of such a mounting of the rocker is shown in detail in FIG. 7.
  • the rubber block 47 is a cylindrical body which is introduced into the annular space between the pivot axis 50 and the bearing eye of the rocker 48.
  • the pivot axis 50 is rotatably mounted in the machine frame.
  • the inner circumference of the rubber block is rotatably connected to the pivot axis 50.
  • the outer jacket of the rubber block is rotatably connected to the inner jacket of the bushing of the rocker 48.
  • the contact roller can move a very small distance, e.g., in front of the growing coil diameter of the spindle in the operating position. Dodge 2 mm.
  • 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 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 along a guide ruler 9, one wing taking over the guidance in one direction and then dipping under the guide ruler, while the other wing takes over the guide in the other direction and then dives under the ruler.
  • the traversing motor 14 is driven at a constant speed, but can also be controllable depending on the signals from a programmer.
  • the housing of the traversing device can be fixed in place.
  • the distance between the contact roller 11 and the traversing thread guide changes, even if the measuring movements of the contact roller are very small and almost negligible.
  • the traversing device 4 is movably mounted in the machine frame of the winding machine.
  • a rocker 49 is used, at the free end of which the traversing device is fastened and which is pivotably mounted at the other end in such a way that the traversing device makes a movement perpendicular to itself and to the contact roller, i.e. can perform a parallel shift.
  • the rocker is freely pivoted in the machine frame.
  • the pivot axis is arranged essentially coaxially with the pivot axis 50 of the rocker 48.
  • the rocker 49 for the traversing device with support 51 lies on the rocker 48 for the contact roller 11.
  • the rocker 49 therefore follows the movements of the rocker 48.
  • it can be folded up independently, which is of great advantage for the maintenance of the contact roller and the traversing device.
  • a cylinder-piston unit 21 which is acted upon pneumatically and which acts on the rocker 48 or the carrier 63 from below, the weight on the contact roller can and thus as a contact pressure on the coil, fully or partially compensated. This is the weight of the traversing device and the contact roller (exemplary embodiments according to FIGS. 1 to 4, 7) or only the contact roller (exemplary embodiments according to FIGS. 5, 6).
  • a sensor 52 is arranged in a stationary manner in the machine frame. This sensor scans the movement of the rocker 48 or in FIG. 5 of the carrier 63, the sensor measuring the distance to the rocker 48 or to the carrier 63, that is to say the path of the rocker 48 or the carrier 63. Depending on the output signal, i.e. e.g. when a predetermined distance is exceeded, the sensor 52 outputs an output signal which is given to a control device 54 for the pin drive 33. The further function will be discussed later.
  • the mode of operation of the winding machine is the same for all exemplary embodiments.
  • the mode of operation is described below using the exemplary embodiment according to FIGS. 1, 2.
  • Fig. 1 the operation of the winding spindle 5 is shown. Only a few layers are wound on the empty tube 10 and the contact roller 11 is in circumferential contact with the coil to be formed. As the bobbin diameter increases, the contact roller makes a slight radial movement. The distance of this movement is detected by the distance sensor 52. Depending on the output signal of the distance sensor 52, the journal motor 33 is controlled via control device 54 in such a way that the journal rotates further by a small angle of rotation in the sense that the center distance between the contact roller and the spindle 5 is increased. The direction of rotation of the spindle is marked by arrow 55.
  • the invention provides two alternative methods for controlling the pintle motor: If the pin motor 33 - as shown in Fig. 7 - is designed as a brake motor, the shaft of the pin motor is initially determined by the brake, so that the pin can not turn when the coil diameter increases. As a result, the contact roller 11 is pressed out of its desired position into an actual position. A certain permissible maximum value for the deviation between the actual position and the desired position of the contact roller is specified in the control device 54. As soon as it is determined by the distance sensor 52 that the deviation between the desired position and the actual position exceeds the predetermined maximum value, the brake is released by means of the magnet and at the same time the rotor of the pintle motor 33 is connected to its current source.
  • journal motor 33 is rotated a little further at a slow but constant speed until it is determined by the sensor 52 that the contact roller 11 has essentially returned to its desired position.
  • the maximum permissible deviation between the target position and the actual position of the contact roller is very small and is, for example, 1 mm.
  • the journal motor 33 is switched off again and the brake is activated instead.
  • the shaft of the journal motor 33 and thus also the journal is again not rotatably secured.
  • the pintle motor 33 is constantly connected to a power source.
  • the very low speed of the journal motor 33 is controlled by means of the distance sensor 52 and the rotary control device 54 so that the contact roller does not leave its desired position or that the deviation between the actual position and the desired position remains constant and as small as possible.
  • This version is a Pin motor 33 required, the speed of rotation does not depend on the torque. Therefore, in this journal motor, the contact pressure between the contact roller 11 and the winding spindle 5 or the coil formed thereon - in the former method not to a rotation of the journal - in the latter method cannot lead to an increase in the rotational speed of the journal.
  • the end position of the coil is marked with (6) and the end position of the spindle with (5). It follows from this that the center of the winding spindle has traveled over a part, the so-called operating area, of the spindle turning circle during the winding travel with the rotation of the pin. This operating range is marked with the reference symbol 57 in FIG. 1.
  • the greatest change in the radial contact pressure now occurs between the initial position in which the spindle 5 is brought into contact with the contact roller 11 for the first time and the position in which the spindle axis of the spindle 5 lies on the tangent 58, which is from the center of the contact roller 11 pulls to the operating range of the spindle turning circle.
  • the angle alpha which the center of the winding spindle 5 has traveled around relative to the center of the contact roller 11, should now be as small as possible.
  • this angle has been shown quite large in order to gain better clarity in the drawing. In reality, this angle is much smaller, and preferably less than 15 °.
  • the particular advantage of the invention is that even with a small diameter ratio (diameter of the empty tube to diameter of the full spool) of less than 1: 3 and also if the wrap angle of the thread on the contact roller 11 is greater than 90 °, the change in contact pressure can be kept low.
  • a further advantage can be seen in the fact that - as can also be seen in FIG. 1 - the coil diameter increases and does not decrease the wrap angle on the contact roller as the coil diameter increases. A reduction in the wrap angle would result in increased slippage of the thread on the contact roller.
  • Another advantage is that the contact pressure assumes a relatively low value during the winding cycle and in particular at the beginning of the winding cycle and increases. This takes into account the fact that the contact pressure when winding the first layers should be relatively low and increase later.
  • FIGS. 5 and 6 illustrate once again what is particularly important according to this invention in the design of the winding machine in order to minimize the fluctuation in the contact pressure between the contact roller and the bobbin.
  • FIGS. 5 and 6 show the geometry of the cross section of the winding machine with the contact roller 11, the winding spindle 5 at the beginning of the winding cycle, the full bobbin 6 at the end of the winding cycle and the operating range B of the spindle turning circle which the pin describes with the axis of the winding spindle.
  • the axis of the winding spindle moves between points A1 and A2 on the spindle turning circle S.
  • the section between points A1 and A2 is referred to here as operating area B, in FIG. 1 with 57.
  • the rocker 48 on which the contact roller 11 is rotatably mounted, and the pivot axis 50 about which the rocker is pivotable.
  • the contact pressure with which the contact roller 11 rests on the bobbin has the direction of the connecting line between the center K of the contact roller and the axis A of the bobbin spindle.
  • One extreme direction goes through points K and A1, i.e. the position of the axis of the winding spindle at the start of the winding cycle.
  • the other extreme direction is the tangent from the axis K to the operating area B of the spindle turning circle S. It can be seen from both FIG. 5 and FIG. 6 that the line of action of the force G exerted by the contact roller is the guide direction of the contact roller, that is, the perpendicular G to the rocker 48 at point K.
  • this force G breaks down into the initial contact force P1, which passes through the initial position A1 of the spindle axis, and a force parallel to the rocker 48. In extreme cases, the force G in turn breaks down into the parallel force of the rocker 48 and that in the tangent T extreme contact pressure PE.
  • the traversing 4 is movably mounted on a rocker 49 such that the distance between the traversing device and the contact roller 11 can be changed.
  • the smallest distance between the traversing device and the contact roller 11, which is maintained during the winding operation, is predetermined by the stop 51. This means that the distance is not changed during the winding cycle. The distance can be increased if the winding machine is to be serviced.
  • the time which is necessary for the bobbin changing process is programmed into a timer and specified by this timer. However, this time is not only specified according to the requirement of the bobbin changing process, but also according to winding-up aspects. This will be discussed later.
  • the timer restarts the rotary drive of the journal by reducing the pressure in the relief device 21 to the level desired for normal operation. This lowers the contact roller again until it lies on the spool.
  • the sensor 52 is now in operation again and controls the rotary drive of the pin 18 as a function of the measuring movements of the contact roller.
  • the invention also offers the possibility of specifying the force with which the contact roller rests on the bobbin and to program it during the bobbin travel in such a way as is desirable or necessary in terms of winding technology. If a constant contact force is desired, the pressure-relieving device is subjected to a slight pressure during the winding-up process after the contact between the contact roller and the forming coil has been established, but this remains constant and serves to part of the total weight of the rocker 48 and the contact roller and traversing device to compensate in order to adjust the contact pressure exerted on the spool by the contact roller to the correct level. However, as already mentioned, it is also possible to control the pressure in such a way that a predetermined course of the contact pressure is achieved via the winding travel.
