Definitions

  • the invention relates to a device for regulating the contact pressure in a bobbin winder between a bobbin to be wound onto a yarn carrier and a roller according to the preamble of claim 1.
  • a bobbin winder in which a thread is wound onto a thread carrier, it is known to drive the bobbin with the aid of a drive cylinder or a grooved drum acting on the outer circumference of the bobbin.
  • the thread carrier of the bobbin is usually rotatably mounted in a pivotable or displaceable bobbin frame. During the winding, the bobbin lies against the driven roller and is set in rotation by this in the frictional connection. Since the winding of the thread to the bobbin should enable good unwinding, it is desirable that the bobbin be carried along without slippage. For this reason, it is known to press the coil against the contact roller with a specific contact pressure.
  • the bobbin is arranged above a roller and with its yarn carrier in a pivotable Coil frame held.
  • the winding frame is designed so that its center of gravity is at a distance from the pivot axis of the winding bracket, so that the weight of the winding bracket presses on the contact roller.
  • the bobbin hinge swivels into a position in which the distance from the center of gravity to the axis of rotation of the bobbin winder becomes smaller and smaller.
  • the force of the weight of the bobbin bar which is thereby becoming ever smaller and pushing on the contact roller, is replaced by the weight of the bobbin.
  • the center of gravity of the bobbin moves from the distance zero to the axis of rotation of the bobbin on the opposite side, so that as the bobbin diameter increases, a counterforce arises in the sense of relieving the contact roller of the bobbin weight.
  • the contact pressure of the coil on the contact roller can be controlled.
  • the desired contact pressure can only be achieved approximately, since this is dependent on the geometry of the coil frame and the coil stroke (coil shape), but also on the coil density.
  • the coil is arranged laterally to a roller and pressed against the roller by springs.
  • two sets of springs working against each other are usually used, with which the desired contact pressure is to be maintained. But even with this embodiment, the desired contact pressure can only be approximately maintained.
  • the winding frame is not pivotally mounted about an axis of rotation, but as Linear guide trained. If the spool is arranged laterally to the roller, a constant contact pressure of the spool against the roller can be achieved with the aid of a weight guided over a roller. With this embodiment, the desired contact pressure can be maintained very precisely, but the linear guide is a relatively complex solution, which makes it difficult to replace the coil. In particular, an arrangement of the coil in any position relative to the contact roller is not possible.
  • WO-A-8 301 610 a generic device for regulating the contact pressure in a winding machine between a bobbin to be wound on a yarn carrier and a roller is known, in which the bobbin is mounted on a pivotable arm and presses against a machine-mounted roller .
  • the arm is connected to a piston, which is guided in a pressure cylinder, which in turn is controlled by a control device based on the pressure or torque exerted by the coil on the roller in such a way that the contact pressure maintains a setpoint.
  • Such a device allows precise control of the contact pressure, however, only with a high level of constructional and control-related effort.
  • the invention is therefore based on the object of specifying a generic device which is structurally simple and robust.
  • the contact pressure is controlled by a device that works on the principle of the scale, the control device being exempt from direct control of the contact pressure and only having to ensure that the scale-like device that regulates the contact pressure is not significantly disturbed is, in particular the balance beam is essentially held in a target position with increasing coil diameter. Since even a relatively large deviation of the position of the balance beam from the nominal position only causes a slight change in the contact pressure, the technical control conditions are considerably more favorable than in known devices, so that high accuracy is achieved can be achieved with little technical effort. This effect can be enhanced by a suitable choice of the lengths of the two arms of the balance beam.
  • the device shown in Fig. 1 has a roller 1, which is designed as a contact roller, drive roller or grooved drum. Above the roller 1, a bobbin 2 is arranged, which is formed by winding a thread (not shown) on a thread carrier (not shown).
  • the yarn carrier is mounted in a winding frame which is pivotally mounted about an axis of rotation 3 and of which an arm 4 is shown in FIG. 1. It is also possible to design the winding frame as a linear guide, which is displaceably guided on a column 22, see FIG. 2.
  • the roller 1 and the winding frame are parts of a winding machine, as are used in various known designs for winding bobbins in the spurs and in the spinning mill.
  • the roller 1 is rotatably mounted on a balance beam 6, which is pivotable about a swivel joint 7 and has two arms 8, 9, of which one arm 8 is arranged on one side of the swivel joint 7 and carries the roller 1 during which the opposite side of the hinge 7 lying other arm 9 carries a displaceable weight 10.
  • the other arm 9 has a substantially greater length than the one arm 8 on which the roller 1 is mounted.
  • a damping device 12 is coupled to the balance beam 6, the function of which is to dampen vibrations on the balance beam 6.
  • the damping device 12 can be a mechanical, hydraulic or pneumatic throttle element, by means of which rapid movements of the balance beam 12 are braked and which is known in various designs.
  • Fig. 1 only one hinge 7 is visible on one side of the roller 1.
  • the roller 1 can also be mounted on its two sides in rotary joints 7.
  • the embodiment in which the roller 1 is supported on one side in a machine-fixed bearing and is supported only on the other side in the one arm 8 of the balance beam 6 is particularly simple.
  • a sensor 13 is arranged, which detects deviations of the balance beam 6 from its desired position and generates a corresponding signal which is fed via a line 15 to a controller 14, in which a signal of an actuating device is fed via a line 16 17 is supplied.
  • the adjusting device 17 engages on the arm 4 of the winding frame and adjusts the winding frame in such a way that the balance beam 6 moves against its desired position.
  • the adjusting device 17 is designed in FIG. 1 as a spindle drive, in which a spindle nut 18 is connected to the arm 4, a spindle 20 cooperating with the spindle nut 18, which spindle 20 being driven by a motor 21.
  • the motor 21 is controlled by the controller 14 via the line 16, as a result of which the adjusting device 17 either loads or relieves the coil 2 in the sense of correcting the position of the balance beam 6 against its desired position.
  • the sensor 13, the controller 14 and the adjusting device 17 form a control circuit with which the contact pressure of the coil 2 on the roller 1 can be maintained very precisely. This is favored by a particularly large length of the other arm 9 of the balance beam 6 compared to the one arm 8.
  • the device shown in FIG. 2 is somewhat similar to that of FIG. 1.
  • the contact pressure is regulated by a control circuit, which is composed of the balance beam 6 with the displaceable weight 10, the sensor 13 and the adjusting device 17 with the spindle nut 18.
  • the spindle 20 and the spindle motor 21 is composed.
  • FIG. 3 shows a further device for regulating the contact pressure of a coil 2 on a roller 1.
  • the roller 1 is mounted on the balance beam 6, which is supported on the swivel joint 7, as in the device according to FIG. 1.
  • the spool 2 is mounted in the pivotable spool frame with the arm 4.
  • the coil frame is also biased by a spring 23 in such a way that it acts to reduce the contact pressure of the coil 2.
  • the balance beam 6 is mechanically coupled to the adjusting device 17, which is designed as a step mechanism.
  • the adjusting device 17 essentially consists of a clamping device 24 and a connecting strap 27, which is coupled to the end of the longer arm 9 of the balance beam 6.
  • the actuating rod 30 is articulated on the arm 4 of the spool frame by means of a swivel joint 31.
  • FIG. 4 shows that the clamping device 25 is a hydraulic system 32 that is actuated by the balance beam 6.
  • a piston 33 is articulated, which cooperates with a cylinder 34.
  • a pressure line 35 leads from the cylinder 34 to a cylinder 36 in which a clamping piston 37 is guided.
  • the clamping piston 37 presses on the adjusting rod 30 and forms the clamping device 24 with the clamping roller 28.
  • the devices described are characterized in that the contact pressure can be maintained regardless of the specific weight of the coil, the coil shape (coil stroke and biconus) and the geometry of the coil frame.
  • the contact pressure is precisely adjustable, and the setting of the contact pressure can be carried out easily and simply. No previous calibration is necessary either, since the contact pressure can be adjusted by moving a relatively small weight 10.
  • a change in the contact pressure during winding is desired, this can be done with a simple addition.
  • the weight 10 is attached to a sliding sleeve 41, while on the top of the sliding sleeve 41 a button 42 is attached with a feeler roller.
  • a link 44 is arranged on the arm 4, along which the feeler roller 43 moves during winding and thereby moves the weight 10 on the balance beam 6.
  • Such devices for changing the contact pressure can of course also be arranged on the embodiments according to FIGS. 2-4.
  • the devices described can also be retrofitted to existing winding machines, since no specific arrangement of the roller 1 and the spool 2 is required.
