Description

  • The invention relates to a multiple winding reversing machine with a winding star and a pressure roller, which is arranged on a pivotable frame which can be pivoted by means of a servomotor about an axis parallel to the axis of the pressure roller, the pressure roller being adjustable relative to the pivot axis by means of another servomotor.
  • In a known device of this type (DE-GM 7728223) the pressure roller is mounted on a pair of toggle levers and connected to the drive of the winding star via a coupling. When the full reel is swiveled into its take-off position, the winder drive takes the swivel shaft that is then coupled. After reaching the end position of the swiveled full reel, the clutch is disconnected and then the pair of toggle levers is swiveled back into the pressing position for the new empty reel by means of a pneumatic actuating cylinder.
  • In another known device of the type mentioned at the beginning (DE-GM 81 24903), drivers are arranged on the winding star, which are designed to rest on driver areas of the toggle lever pair and carry the pressure roller system on the winding roller during the turning process.
  • Both known devices have the disadvantage that the wrap angle of the material web on the pressure roller changes constantly during the turning process. In both cases, this is a consequence of the forcible coupling between the movement of the winding star and the movement of the pressure roller. The constant change in the wrap angle of the web on the pressure roller is the cause of air inclusions between the layers of the winding roll and for disturbances in the web feed due to wrinkling and web run.
  • On the basis of this prior art, the object of the invention is to design a multiple winding reversing machine of the known type in such a way that a uniform web feed and perfect winding is ensured even during the turning process.
  • This object is achieved according to the invention in that the adjustment of the servomotors during the swiveling process of the winding star as a function of both the diameter of the winding and the swiveling position of the winding star can be regulated in such a way that the wrap angle of the material web on the pressure roller at least in the essential always remains the same.
  • In a practical embodiment, the relative position of the pressure roller to the roll is determined by means of a scanning device for the winding diameter and a scanning device for its swivel position, and the determined values are fed via a corresponding signal transmitter to a function transmitter or computer, the output information of which, together with or from a position detector of the pressure roller, or one of them Actual value information originating from the connected element is fed to a position controller for generating an actuating signal for at least one servomotor.
  • It has proven to be expedient that an actuator for changing the position of the pressure roller is pivotally mounted about an axis parallel to the winding axis.
  • In a preferred embodiment, the first servomotor or the associated first actuating device can be pivoted by means of a second servomotor.
  • It has proven particularly expedient for the first servomotor to consist of an electric motor with a spindle and a spindle nut, and for the spindle nut to be connected to the bearing for the pressure roller.
  • The second servomotor is expediently a pneumatic piston-cylinder unit.
  • Furthermore, according to a further feature of the invention, at least the second servomotor can be a hydraulic piston-cylinder unit.
  • Finally, it has proven to be expedient for the electric servomotor to be a DC motor.
  • Instead of an analog control, a digital control using microprocessors can also be used.
  • A preferred exemplary embodiment of the invention is described in detail below with reference to the drawing. Show it
    • 1 shows a schematic side view of the winding machine with the pressure roller system in the winding position,
    • 2 the winding machine with the pressure roller system in different positions,
    • 3 is a front view of the winding machine with a pressure roller system,
    • Fig. 4 shows the block diagram of a system for the proposed control.
  • A winding star designated 4 in total is provided with three winding positions 1, 2 and 3 and is driven by a turning motor (not shown) when the reel is changed. A swivel frame 5 is provided under the winding star 4, on which laterally parallel spindles 6 and 7 are rotatably mounted. The spindle 6 is rotated by an electric motor 13, which drives the spindle 7 at the same speed via a drive element, for example a drive chain 14.
  • The spindles 6 and 7 work together with spindle nuts 6a and 7a, which are provided at one end of a frame 8. The frame 8 carries a freely rotatable pressure roller 9 at the end opposite the spindle nuts 6a and 7a.
  • The pivot frame 5 is pivotally mounted about the longitudinal axis of the shaft 12 arranged in a stationary manner. Accordingly, the frame 8 with the pressure roller can also be pivoted about the same longitudinal axis. A pneumatic cylinder 10 or 11 is attached to the swivel frame 5 on both sides. The two pneumatic cylinders are used to generate the contact pressure of the pressure roller 9 on the roll.
  • The web of material 16 is fed to the winding 17 in the winding position via a horizontal, movable contact roller 18 which escapes as the winding increases. The contact roller 18 lies directly on the run-up point of the web 16 on the winding 17 and prevents the wrapping of air. The pressure roller 9 which bears against the winding 17 in the vicinity of the contact roller 18 is pressed onto the winding 17 by means of the pneumatic cylinders 10 and 11 with a constant or programmable contact pressure.
  • Shortly before the winding 17 has reached its final diameter, the winding process of the winding star 4 is initiated. The winding star 4 rotates counterclockwise into the removal position, which is shown continuously drawn in FIG. During this process, the pressure roller 9 slides between the contact roller 18 and the winding 17 in a preprogrammed sequence and always remains in contact with the winding 17. The pressure roller 9 is pushed into a position which is most favorable for guiding the material web during the turning process, in which it assumes a wrap angle a determined as favorable. During the turning process, the wrap angle a originally assumed is always kept unchanged, namely with constant contact of the pressure roller 9 on the winding 17. The constant wrap angle a and the constant contact of the pressure roller 9 during the pivoting movement of the winding star ensure that neither air pockets in this phase wrinkling or shifting of the web 16 can still occur.
  • The constant wrap angle of the web 16 on the pressure roller 9 is achieved by the electronically controlled adjustment of the electric motor 13. The diameter of the winding 17 is determined by means of a scanning device 19, namely by measuring a characteristic distance between the winding 17 and the contact roller 18 . Furthermore, the swivel position of the winding star is determined by a corresponding scanning device, namely a reversing potentiometer 20. Both the measured value for the winding diameter and the measured value for the swivel position of the winding star are fed to a function transmitter or computer 21 via corresponding signal transmitters. The computer 21 determines the correct target position of the pressure roller 9 and feeds a signal to the position controller 22. The position controller 22 also receives actual value information about the position of the pressure roller from a position detector 15 and the position controller 22 can control the electric motor 13 after comparing the information fed into it so that the pressure roller 9 always assumes the correct position and that Wrap angle a is always kept the same.
  • As soon as the winding 17 has reached the removal position, the winding star 4 is stopped. The web 16 is separated from the full roll 17 by means of an automatic changing system (not shown) and is placed on the empty winding point 3 and wound further.
  • The actuating cylinders 10 and 11 pivot the swivel frame 5 back into the starting position according to FIG. 1, while the electric motor 13 also adjusts the pressure roller 9 back into the starting position according to FIG. 1. In this starting position, the pressure roller 9 comes into contact with the new winding in the winding position.
