Definitions

  • the present invention relates to a device and a method for winding a thread onto a bobbin tube to form a bobbin, with a machine frame and with a controller, with a support roller rotatably mounted in the machine frame for supporting the bobbin tube and with a winding mandrel for holding the bobbin tube, wherein the winding mandrel is held on a swivel lever which is rotatably mounted on a rotary axis in the machine frame.
  • Such winding devices are used in textile machines of various designs, for example end spinning machines, rewinding machines or winding machines.
  • the bobbin or bobbin sleeve is rotatably mounted between two holding arms or on a winding mandrel.
  • the two holding arms or the winding mandrel are in turn held in a common swivel arm with a swivel axis.
  • the bobbin tube lies on a support roller and is set in rotation by a drive, whereby a thread or yarn fed between the support roller and the bobbin tube is wound onto the bobbin tube and a bobbin is formed.
  • bobbin tubes in cylindrical or conical shape made of different materials, such as plastic or paper, are used.
  • the bobbin tubes can be designed with or without side flanges.
  • the bobbin tube is driven directly via a motor which rotates at least one of the tube receptacles or the bobbin mandrel, or indirectly via a friction roller arranged parallel to the bobbin tube.
  • the friction roller also serves as a support roller.
  • the friction roller can be designed as a so-called grooved drum.
  • the grooved drum is provided with a yarn guide which is guided in slots by the rotation of the grooved drum such that the thread is moved back and forth.
  • the traversing of the thread is to be provided by a separate laying unit and the bobbin tube is supported by a separate support roller. The thread is thereby between the support roller and the bobbin tube respectively clamped to the thread already on the bobbin tube and thereby deposited on the bobbin tube.
  • Winding devices are known from the prior art which are equipped with a swivel drive for this movement. It is also known that swivel drives can be equipped with an angle measurement, which means that a corresponding control always knows in which position the swivel drive is located.
  • a disadvantage of the known designs of the winding devices is that a complex construction and drive technology must be used to move the coil to maintain the contact forces.
  • a winding device for winding a thread onto a bobbin sleeve to form a bobbin comprises a machine frame and a controller, a support roller rotatably mounted in the machine frame for supporting the bobbin tube and a winding mandrel for holding the bobbin tube, the winding mandrel being held on a pivoted lever which is rotatably mounted on a rotary axis in the machine frame.
  • the pivoting lever is designed with two lever arms, with the winding mandrel for the bobbin tube being provided on a first lever arm and a linear drive for moving the pivoting lever about the axis of rotation being provided on a second lever arm.
  • the linear drive is connected to the second lever arm with a connecting rod via an axle bolt and is pivotably held in the machine frame.
  • a force measurement is arranged between the axle bolt and the bracket of the linear drive in the machine frame.
  • the use of a winding mandrel instead of a previously customary creel considerably simplifies the construction of the winding device.
  • a single swivel lever fastened on one side to the winding mandrel is sufficient for storing the winding mandrel.
  • the pivoting lever comprises two lever arms, with an axis of rotation being provided at the point of intersection of the two lever arms, which forms a fixed point and is connected to the machine frame in a stationary manner.
  • the linear drive attached to the second lever arm is rotatably fastened via the connecting rod with an axle bolt. At the end of the linear drive opposite the axle bolt there is another rotatable attachment to the machine frame.
  • the linear drive moves the coil mandrel towards or away from the support roller with a translation corresponding to the two lever arms
  • the force measurement can be arranged on both sides of the linear drive.
  • the linear drive When the linear drive is actuated, the bobbin tube is pressed onto the support roller via the swivel lever.
  • the resulting contact force can be increased or decreased by a corresponding movement of the linear drive.
  • the force measurement can be designed as a hydraulic or mechanical force measurement.
  • the force measurement is advantageously implemented as a load cell arranged between the axle bolt and the holder of the linear drive. This enables a simple and compact design, and a load cell can also be coupled directly to a controller in a simple manner.
  • force transducers can be used in load cells.
  • the use of force transducers is known, in which the force acts on an elastic spring body and deforms it.
  • the deformation of the spring body is converted into a change in electrical voltage via strain gauges whose electrical resistance changes with the strain.
  • the electrical voltage and thus the change in strain are registered via a measuring amplifier. Due to the elastic properties of the spring body, this can be converted into a measured force value.
  • Bending beams, ring torsion springs or other designs are used as spring bodies.
  • Piezoceramic elements are used in another type of load cell. The directional deformation of a piezoelectric material creates microscopic dipoles within the unit cells of the piezoelectric crystal.
  • the linear drive is connected to the mount via the load cell.
  • the load cell is designed in such a way that it can be used as part of a holder.
  • the load cell can also be attached to the machine frame so that it can rotate.
  • the linear drive can be provided as a pneumatic or electric drive. However, it is advantageous if the linear drive is an electric stepping motor with a resolution of less than 0.06 mm per step.
  • Linear drives are known in a variety of designs. However, in order to enable the contact force of the bobbin on the support roller to be regulated as precisely as possible, a linear drive with the smallest possible increment is advantageous. It has been found that with today's arrangements of the winding devices, a pitch of less than 0.06 mm is preferable.
  • the design of the linear drive should also be selected in such a way that manual movement of the swivel lever against the de-energized linear drive is possible. In the event of a fault, it may be necessary to manually lift the bobbin off the support roller and this should be possible without mechanically decoupling the linear drive.
  • a drive for the winding mandrel is arranged on the first lever arm.
  • the additional weight of this drive which also influences the contact force of the bobbin tube on the support roller, can be absorbed by the corresponding movement of the linear drive.
  • This direct drive of the winding mandrel instead of an indirect drive of the bobbin with the aid of the support roller allows the winding speed to be regulated without slip. There are also fewer losses in the form of friction and mechanical transmission, which leads to lower energy consumption for the coil drive.
  • a handle with a release button for manual slackening of the winding mandrel is provided on the second lever arm.
  • the bobbin tube is held on the winding mandrel by spreading the winding mandrel. A diameter of the winding mandrel is increased by spring force and the bobbin tube is thus clamped.
  • the handle also serves to move the bobbin or the bobbin mandrel away from the support roller or towards the support roller manually without the aid of the linear drive. A moment of resistance of the linear drive can be overcome by a slight manual force on the swivel arm or the handle and the bobbin or winding mandrel can also be brought into the desired position manually.
  • a stop is preferably provided on the pivoting lever, which prevents the winding mandrel from resting on the support roller if there is no bobbin tube.
  • an advantageously adjustable stop is provided on the first or on the second lever arm of the pivoting lever. This prevents the winding mandrel from pivoting against the support roll until it touches it. Since the thread to be wound up runs over the support roller in a winding process, ie is guided by a surface of the support roller, it is important that the surface of the support roller is not damaged.
  • the winding device has a machine frame and a controller and a support roller rotatably mounted in the machine frame and a winding mandrel.
  • the bobbin rests on the support roller and the winding mandrel is held on a swiveling lever that is rotatably mounted in the machine frame.
  • the pivoting lever has a first holding arm with the winding mandrel and a second lever arm with a linear drive, the linear drive being connected with a connecting rod to the second lever arm via an axle bolt and pivotably held in the machine frame.
  • a force measurement is arranged between the axle bolt and the bracket of the linear drive in the machine frame. Before the winding process, an empty bobbin tube is pushed onto the winding mandrel. The winding mandrel is then pivoted by the linear drive via the pivoted lever until the bobbin tube rests on the support roller: The force measurement measures a contact force between the support roller and the bobbin tube and the controller uses the linear drive to move the pivoted lever until a specified contact force is reached will.
  • the contact force is regulated in a predetermined range during a winding cycle by controlling the linear drive.
  • a variable is determined which, taking into account the machine-technical conditions, is directly proportional to the contact force.
  • the contact force between the bobbin or bobbin sleeve and the support roller is not measured directly, but the force with which the linear drive is supported against the machine frame.
  • the weight of the pivoting lever together with any existing drive of the winding mandrel and the winding mandrel itself must be taken into account in their influence on the force measurement.
  • the forces acting on the force measurement as a result change as the diameter of the spool increases due to the pivoting movement of the pivoting lever and an associated change in a horizontal distance between the winding mandrel and its stationary axis of rotation.
  • the winding mandrel with an empty bobbin tube is pivoted once for calibration.
  • Such a calibration by pivoting the winding mandrel up once with an empty bobbin tube must be repeated each time a different bobbin tube is used.
  • the pivoting movement enables the controller to recognize the forces and then take them into account.
  • the force measured during the winding process is proportional to the contact force due to the leverage effect and taking into account the corresponding corrections due to the machine-technical conditions.
  • the force measured in this way is determined by the weight of the bobbin and the pressing force of the bobbin on the support roller, which is exerted by the pivoting lever or the linear drive assigned to it.
  • the lever arm of the pivoting lever on the spool side is pushed away from the support roller and at the same time held in position by the linear drive by the opposite lever arm of the pivoting lever or at least its movement is impeded.
  • the control provided compares the measured force with a target value and corrects the position of the swivel lever by means of a linear movement of the connecting rod so that the measured actual value of the force corresponds to a specified value corresponds to the target size.
  • the thread is always placed on the bobbin under the same contact pressure or a contact pressure adapted to the winding cycle over an entire winding cycle. Without such a regulation, more and more compacted thread layers would result on the bobbin over the winding cycle, which would have a negative effect on a later powdering hold in the subsequent processes of thread processing. Furthermore, the contact pressure can be reduced with increasing spool size, which has the advantage that the spool core is not pressed together by the outer layers. A high quality and uniformity of the coils produced can thus be achieved.
  • the diameter of the bobbin increases continuously as a result of the thread running onto the bobbin, which leads to a rotary movement of the pivoting lever and thus also to a change in the load on the force measurement.
  • the controller detects this change by measuring the force and can restore the previous balance of forces by moving the linear drive accordingly.
  • the spool is switched off.
  • the current diameter of the bobbin in the event of a disruption in the bobbin operation is known at all times by counting the steps of the linear drive, so that before resuming operation it can be decided on the basis of the diameter whether the bobbin should be continued with the bobbin that has already been started or whether the bobbin should be changed by an empty bobbin tube is advantageous.
  • the winding is preferably stopped and the bobbin is lifted off the support roller by the linear drive.
  • the specified coil diameter can be determined in various ways.
  • the length of the wound thread can be determined or calculated via the winding speed and the current coil diameter can thus be inferred.
  • sensors it is also possible to use sensors to detect the deflection of the pivoted lever or the movement of the linear drive and to deduce the bobbin diameter from this.
  • the concept of reaching a predetermined spool diameter can also include the specification of a certain thread length, duration of a spool or movement of the linear drive or degree of pivoting of the pivoting lever be understood.
  • the bobbin If the bobbin is lifted, it can be removed from the bobbin mandrel manually or with the help of an automatic removal device after or while the clamping device of the bobbin mandrel has been released manually or automatically. In the raised state, a final weight of the finished coil can be determined by measuring the force. After pushing an empty bobbin tube onto the winding mandrel and tensioning it, the pivoting lever is moved by the linear drive until the bobbin tube rests on the support roller and a predetermined contact force is reached.
  • a winding machine or a rewinding machine is preferably equipped with a device as described above, which makes the machine itself easy to operate and inexpensive to manufacture.
  • figure 1 shows a schematic plan view and figure 2 a schematic side view in direction X of figure 1 an embodiment of a winding device 1.
  • the winding device 1 comprises a winding mandrel 7 which is rotatably mounted on a pivoting lever 8.
  • the winding mandrel 7 is set in rotation by a drive 17 also held on the pivoting lever 8 .
  • An alternative to this form of drive would be an indirect drive of the winding mandrel 7 via a support roller 3.
  • a bobbin tube 5 is held non-rotatably on the winding mandrel 7 with the aid of a clamping device (not shown).
  • the clamping device of the winding mandrel 7 can be released via a release button 19 which is attached to a handle 18 on the pivoting lever 8 when a full bobbin 2 or the bobbin tube 5 has to be changed.
  • the pivoting lever 8 is held stationary on a rotary axis 9 on the machine frame 6 .
  • the pivoting lever 8 consists of a first lever arm 10 and a second Lever arm 11.
  • the winding mandrel 7 with its drive 17 is fastened to the first lever arm 10 .
  • a linear drive 12 is attached to the second lever arm 11 via an axle bolt 13 .
  • the pivoted lever 8 By connecting the linear drive 12 to the pivoted lever 8 via the axle bolt 13 at an outer end of the second lever arm 11, the pivoted lever 8 is rotated about the axis of rotation 9 when the linear drive 12 moves, with the result that the winding mandrel 7 moves at its distance is changed to the backup roller 3.
  • the linear drive 12 is connected to the axle bolt 13 via a connecting rod 16 and is rotatably fastened to the machine frame 6 with a bracket 14 on the side opposite the axle bolt 13 .
  • a force measurement 15 is inserted between the holder 14 and the linear drive 12 .
  • the support roller 3 Arranged parallel to the bobbin axis of the winding mandrel 7 is the support roller 3 on which the bobbin tube 5 comes to rest due to the pivoting movement 25 of the pivoting lever 8 about the axis of rotation 9 .
  • the support roller 3 is rotatably fastened in the machine frame 6 by means of appropriate supports 27 .
