Definitions

  • the invention relates to a winding device according to the preamble of claim 1 and a method for winding a lap according to the preamble of claim 8.
  • a winding change is required to wind up a continuously fed web of material, in particular a plastic web.
  • a continuously fed web of material in particular a plastic web.
  • an empty winding tube is brought up to the web.
  • the material web is then cut and the newly created web beginning is brought into contact with the new winding core. Due to an adhesive or adhesive effect, which can be caused, for example, by an adhesive tape or by an electrostatic attraction, the beginning of the web adheres to the new winding core, so that a new winding is created.
  • Both the new winding tube and the finished winding are located on winding shafts.
  • these two winding shafts are arranged on a support element which can be moved relative to a machine frame.
  • a support element is designed as a turret unit, for example as a turntable or turnstile, and is rotatably mounted in the machine frame or a component thereof.
  • the support unit In the course of changing the roll, the support unit is moved so that the roll that is currently being wound is moved out of the winding position and the new winding tube takes its place. The lap change described above then takes place.
  • the material web is often cut lengthways into several partial webs, so that several rolls arranged next to one another in the axial direction of the winding shaft are produced.
  • a contact roller presses the material web onto the roll, so that as little or a defined amount of air as possible passes between the individual layers of the roll.
  • the contact roller is no longer in contact with the roll, so that an additional pressure roller takes over the task of the contact roller to avoid air entrapment.
  • the pressure roller is rotatably mounted in a bearing arm. This bearing arm is in turn carried by a support arm, at least part of the support arm being movable relative to the support arm. The support arm, in turn, is movably supported in the machine frame.
  • the object of the present invention is therefore to create a winding device with a plurality of winding shafts which overcomes the above-mentioned disadvantages.
  • At least one positive guide element is provided with which the movement of the bearing arm relative to the support arm can be controlled as a function of the position of the support arm relative to the machine frame.
  • the support arm can for example be linearly displaceable, for example along rails and / or along a rotatable spindle. In this case, the support arm assumes different, in this case lateral, positions during the movement.
  • the support arm can also be arranged on the machine frame so as to be rotatable or pivotable by means of rotary or pivot bearings, with different angular positions being able to be assumed.
  • a combination of a linear and a pivoting or rotating movement is also conceivable.
  • the positive guide element according to the invention now couples the movement of at least parts of the bearing arm to the movement of the support arm, with the pressure roller, which can have a rubberized outer surface, following a defined and fixed path.
  • the movements described in the context of the invention essentially take place in at least one plane which runs orthogonally to the winding or winding shaft. A possible movement parallel to the axis of rotation of the roll is not relevant here.
  • a drive is provided with which the support arm can be moved relative to the machine frame.
  • this is a piston-cylinder unit, for example a pneumatic cylinder, in particular a double-acting pneumatic cylinder.
  • a piston-cylinder unit has the advantage that it provides a force which can be used to press the pressure roller against the roll.
  • no drive is necessary, but only a force-providing means, such as a resilient element, which acts on the support arm in such a way that the bearing arm presses the pressure roller against the roll.
  • a piston-cylinder unit such as a pneumatic cylinder.
  • the actual movement of the In this case, the support arm can be caused by movement of the support element.
  • the power flow runs from the support element via the roll, the pressure roller and the load arm in the direction of the support arm. This configuration is mechanically very easy to plan and manufacture.
  • an electric motor can also be provided which, for example, acts on the support arm via a spindle-spindle nut combination.
  • a further force supply means can be available which presses at least parts of the bearing arm and thus the pressure roller against the roll.
  • An electric motor can also be a linear electric motor.
  • a piston-cylinder unit can be used to provide a pressure force with which the pressure roller can be pressed against the roll.
  • this pressing force for example as a function of the position of the support arm and / or the speed of movement of the support arm and / or the diameter of the roll. This makes it possible, for example, to keep the proportion of the pressing force acting perpendicularly on the roll constant, while the total pressing force varies. Even a possible influence of the weight on the pressure roller can be compensated in this way.
  • a control or regulation comprising a computing and control device can be provided which controls the movement drive as a function of calculated or measured parameters.
  • An additional force supply device can also be provided with which a pressure force for the pressure roller on the roll can be provided, which can be controlled by the computing and control device.
  • the positive guide element comprises a guide track with which the movement of the bearing arm can be controlled.
  • a guide track can be, for example, a groove or a rail. Even a track that can be scanned by sensors can be provided. A path that can be scanned magnetically, optically or electrically is ideal here.
  • a guideway can also be stored as a data record in an electronic control device. Based on the current position of the support arm, the control device can then determine the associated position of the support arm and correspondingly control a drive that moves the support arm relative to the support arm, so that a fixed movement of the support arm occurs due to the movement of the support arm.
  • the guide track is preferably connected to the machine frame in which the support element is also mounted. The provision of a guide track results in a very easily controllable setting of the bearing arm relative to the support arm.
  • the positive guide element comprises a guided element which can be moved along a guide track and to which the bearing arm is connected directly or indirectly.
  • a guideway can be designed as described in the preceding paragraph.
  • the guided element thus follows the specified guideway and transfers the movement to the bearing arm. This applies in particular to the case that the guide track and the guided element interact purely mechanically.
  • a further drive may be necessary in order to apply the force necessary for the movement of the bearing arm.
  • the guided element is in particular connected directly or indirectly to the bearing arm.
  • the guided element is attached directly to the bearing arm; in the second case, a further component can be provided, for example a lever, in order to transmit the actuating forces to the bearing arm.
  • the guided element can preferably be configured to match the guide track.
  • a sliding block or a roller which grips into the groove, can run within a guide track designed as a groove.
  • a slide can run on a guide track designed as a rail and can encompass the guide track in a U-shape.
  • at least two rollers can also be provided, which laterally engage the guideway.
  • the guided element and the support arm are coupled to one another.
  • the guided element can also be movable relative to the machine frame during the movement of the support arm.
  • the guided element can be fixedly or movably attached to the support arm.
  • parts of the guided element engage in a forced guidance of the support arm.
  • the support arm and the guided element are connected via a lever pivotably arranged on the support arm. Coupling can also take place electronically, in which case, for example, a rotary encoder can be provided on the support arm, the data of which is given to the control device already described.
  • the guided element is the component that transmits the travel to the bearing arm, for example the shaft of a position motor and / or a groove in which, for example, a threaded shaft of a position motor engages.

  • This winding device comprises as a supporting part a machine frame, of which a supporting frame 102 is visible, which for the sake of simplicity is shown as a rectangular plate, but in practice can assume any function-oriented design .

  • this rotation element 104 a plurality of winding shafts are arranged via rotary bearings, which are not shown in more detail. In the present example there are three winding shafts 105, 106 and 107.
  • the axes of rotation of the winding shafts are designated 108, 109 and 110.
  • the individual winding shafts are shown in different operating states.
  • the winding shaft 107 is in an unloading position, with finished laps being drawn off the winding shaft 107.
  • the winding shaft 105 is in a standby position in which it is equipped with one or more winding tubes 111.
  • the winding shaft 106 is in a winding position, the winding shaft being equipped with one or more winding tubes 112 and the winding tube or tubes each being or has been wound with a web 113 and forming or forming one or more windings 114.
  • the winding can also be wound without a winding tube.
  • the web 113 is preferably a plastic film web, in particular a stretch film. However, it can also be a paper web or a metal foil web (e.g. aluminum foil). At least one longitudinal cutting element can be provided in order to produce several parallel running webs, so that several rolls located on the same winding tube can be wound.
  • the web 113 is preferably fed to the winding device 101 via various guide rollers, which are not shown, and is pressed against the respective winding 114 during the winding by one or more contact rollers 115, whereby the amount of air between the individual Layers is wrapped, can be controlled.
  • the contact roller 115 is no longer in touching contact with the lap 114. It has been removed from the lap or laps in preparation for a so-called lap change.
  • the contact roller is movably mounted on the machine frame, so that it can be moved relative to the machine frame and / or thus also relative to the winding shaft 106.
  • the contact roller can be arranged in a pendulum arm which can be pivotably mounted in the support frame 102. However, it can also be stored in carriages which can be moved along rails. In any case, a drive is required for the movement of the contact roller relative to the winding shaft.
  • the function of the contact roller 115 is performed during the lap change by the pressure roller 120, which is thus referred to as the auxiliary contact roller could be.
  • the pressure roller 120 is therefore preferably placed against the roll before the contact roller 115 is moved away from the roll 114. This can take place, for example, in an intermediate position in which the rotation element 104 stops briefly between the winding position and the unloading position, so that the pressure roller 120 can be applied and the contact roller 115 can be removed.
  • the pressure roller 120 can be moved over a wide adjustment range relative to the support frame 102, so that it can remain in contact with the roll 114 as long as the roll is in the unloading position, which is in the Figure 1 is occupied by the winding shaft 107, is moved.
  • the pressure roller 120 is rotatably mounted on a lever 121, which is controlled with respect to its position relative to the machine frame via a positive guide, which is designed as a cam track 122 in the present drawing.

  • the lever 121 can be moved linearly in the direction of the double arrow S relative to the component 124.
  • the component can, for example, be a tubular component or comprise another linear guide.
  • a drive is provided which, for example - as shown - is designed as a piston-cylinder unit 125, the cylinder being attached to the machine frame and the piston, which is slidably mounted in the cylinder, being attached to the component 124.

  • a slide 126 which can be mounted displaceably along a rail 127.
  • the cylinder of the piston-cylinder unit 125 is now subjected to a force which acts in the direction of the roll 114. Due to the preferred application of compressed air, the piston-cylinder unit acts like a resilient element. As a result, the pressure roller 120 is now also pressed against the roll 114. By selecting the air pressure in the piston-cylinder unit, the force with which the pressure roller presses on the roll 114 is set. The air pressure can additionally be varied as a function of various parameters, such as the current rotational position of the rotary element 104.
  • the Figure 3 now shows the situation in which lap 114 has reached the unloading position and the new lap 111 has reached the winding position. It is also shown that the contact roller was brought into contact with the new roll 111 and then the web 113 with a not shown Separating device was transversely separated so that the new beginning of the web was set on the new lap. The trailing end of the old web section is still wound onto the reel 114, the pressure roller 120 still being positioned on the reel 114.
  • the curved path 122 can be shaped at the lower end in such a way that a further movement of the lever 121 also removes the roll from the roll in the horizontal direction. In this way, a removal device 130 can now move unhindered from below to the lap 114 in order to be able to remove the lap. This situation is in the Figure 4 shown. After the roll 114 has been removed, the pressure roller 120 can be moved back to a standby position so that the described process for changing the roll can be repeated.
