Definitions

  • the invention is directed to a device for winding up and changing laps of web-shaped material according to the preamble of claim 1 and a method for this according to the preamble of claim 8.
  • Winders are used to wind up web-shaped materials, such as plastic films, paper webs, metal foils or textiles.
  • the material webs to be wound come directly from the manufacturing process and are put into rolls, so-called laps, for further processing.
  • Winders are also used for films, for example from blown film lines.
  • Tubular films are formed in these systems at high speeds and, after being laid flat, must be continuously wound onto reels without reducing the production speed in the system. Once the roll has reached a predefined size, it has to be changed; this also happens without stopping the production of the endless material web or changing the production speed.
  • the known winding devices include turret winders, contact winders and center winders.
  • one or two opposite turntables are rotatably mounted in a machine frame and accommodate at least two rotatably mounted winding points.
  • a first winding point is in the winding position and a second winding point is in a loading or unloading position in order to receive a new winding shaft or to deliver a finished winding. If the lap has reached its target size in the winding position, the first and the second winding point change their position by turning the turntable and the next lap can be wound up.
  • the disadvantage here is that a large amount of space is required for large winding diameters.
  • winders with a linear movement of the winding positions including contact and center winders
  • the roll to be wound is pressed against a driven contact roller, the roll is not driven separately.
  • a so-called pre-winding point is necessary for these winders.
  • the lap In the case of the central winder, the lap is driven centrally in the winding point. At the same time, it can be pressed against the contact roller or operated with a gap to the contact roller.
  • the disadvantage of the two last-mentioned winders is that when a roll is changed, the winding must be transferred from the pre-winding point to the winding point.
  • the pressure of the roll against the contact roller is not defined, so that different winding conditions arise.
  • Winders are designed for left-hand winding, right-hand winding or both types.
  • the winding direction of the web-shaped material depends on the subsequent process steps and on which side of the film must be on top for this process step.
  • the left or right winding allows the pretreated side (corona), which is printed in a subsequent process step, to be wound inside or outside.
  • the arrangement of the sealing layer in the coextrusion composite during extrusion is independent of a required internal or external arrangement during winding.
  • the winding shaft then has the corresponding direction of rotation.
  • the winding device has two winding points which are arranged in a winding frame and which work in conjunction with a contact roller.
  • the winding shafts of the two winding stations are each driven independently by motors.
  • the winding points can be moved on horizontal guide rails between the winding point and the delivery point for the finished lap.
  • the contact roller is motor-driven and can be lowered. When changing the winding position it is vertically down between the winding position and move to a parking position.
  • the new winding shaft is inserted in the idle state, while the second winding shaft is in the operating state.
  • the EP 2 261 152 A1 discloses a winder having a front winding base frame and a rear winding base frame each provided with winding arms that hold winding shafts to be able to vertically rise and descend, the winding arms being attached to the front winding base frame and the rear winding base frame, to be exchanged between the front winding base frame and the rear winding base frame.
  • a front contact roller frame and a rear contact roller frame are each provided with contact rollers to vertically ascend and descend, and the contact rollers are attached to the front contact roller frame and the rear contact roller frame to be interchangeable between the front contact roller frame and the rear.
  • the EP 1 947 043 A1 discloses a winding device for winding a continuously tapering material web onto successively provided winding shafts with the formation of coils of the material web on the winding shafts, comprising a contact roller rotatably mounted in the winding device, via which the material web to be wound can be felt and transferred to the winding shaft or the coil forming thereon is, a winding station with a winding shaft receiving device for receiving and rotatable mounting of a winding shaft, the winding shaft receiving device being displaceable relative to the contact roller from a winding position to a removal position according to the diameter of the coil forming on the winding shaft and a rotary drive for the recorded winding shaft, a winding shaft feed for feeding a new winding shaft to be exchanged for the winding shaft wound with the material web into the winding shaft receiving device, a transverse cutting device for transversely cutting the material web in the course of a winding shaft change, the winding shaft receiving device each comprising two winding shaft receiving stations Have
  • Films are structured differently in terms of their number of layers and the types of material used in the layers. They do not have to be symmetrical in their layer structure. Each blown film has a tube inside and a tube outside. When winding, it is desirable that, depending on the type of film layers and the type of further processing of the film, a special side is on the outside or inside. To make this possible, it is important that winders are designed to be both right and left winding.
  • the invention is therefore based on the object of creating a solution which makes it possible to provide a winder which enables left-hand winding as well as right-hand winding and wherein the winder is designed without a pre-winding point.
  • the winder according to the invention has a winding point arranged in a machine housing.
  • This winding station has two central drives that alternate come into use.
  • the central drives are arranged one on each side of the machine housing. These work together with a driven winding shaft guide.
  • the respective central drive is coupled to the driven winding shaft guide and moved on guides between a parking position and a winding position.
  • the central drives are used alternately.
  • the central drive in use is coupled with the winding shaft guide, the second central drive is permanently coupled in its waiting position.
  • the central drives are arranged on the outside of the machine frame and interact with the winding shaft guide arranged inside, which moves on essentially horizontal guides, ideally on horizontal guides.
  • the winding shaft also lies on a support which is arranged parallel to and above the winding shaft guide.
  • the central drive is preferably coupled in the waiting position on the machine housing or a separate frame.
  • a contact roller unit In the winding position, a contact roller unit interacts with the winding shaft or the winding.
  • the contact roller unit is designed to be movable, e.g. pneumatically or electrically. It can be moved essentially horizontally between the winding position and a contact roller parking position.
  • the contact roller unit comprises the contact roller, a guide and the pressure. Alternatively, the roll can also be wound with a gap, then the contact roller does not press against the roll, the film runs over the contact roller.
  • Separating devices are arranged above and below the contact roller unit. They have two functions. On the one hand, they raise or lower the film web during the winding change in order to bring the new winding shaft into the winding start position; on the other hand, they separate the film web during the winding shaft change process.
  • the separation and lifting can also be carried out in separate devices, so that above and below the Contact roller unit each have a lifting or lowering unit and a separate separating device are arranged.
  • the device also has a winding shaft transport unit for the newly inserted winding shafts. It is designed essentially vertically and arranged in the area between the winding shaft guide and the contact roller unit. Depending on the winding direction, the new winding shaft is transported from above or below via the winding shaft transport unit to the winding level above or below the film web.
  • the new winding shaft is moved from below with the aid of the winding shaft transport unit onto the winding level.
  • the winding shaft is inserted into the winding shaft transport unit from above and driven down with it onto the winding plane.
  • the new winding shafts can be transported to the first-mentioned winding shaft transport unit via further winding shaft transport units and can be transferred to the latter so that they can be transported in the direction of the winding plane.
  • the winding shafts are fed into the machine from the side and placed in the winding shaft transport unit.
  • a winding shaft is picked up by a first central drive and the shaft winding guide in the winding operation.
  • the central drive drives the winding shaft and the film web, which is guided to the winding shaft via a contact roller, is wound onto the winding shaft.
  • the contact roller is pressed against the roll.
  • the contact roller is designed to be movable for this purpose.
  • the winding moves, while its diameter increases, with the Central drive and the winding shaft guide in the direction of the roll dispenser, away from the contact roller.
  • the contact roller presses permanently against the roll so that no air is wrapped in, the film does not run and thus can guarantee a uniform roll quality with a defined contact force.
  • the roll is wound up until the target diameter is reached.
  • the lap change is prepared. First, the winding shaft feed and the winding shaft change for the case of right-hand winding are described. A new winding shaft is inserted into the winding shaft transport device and guided upwards into a first parking position in front of the winding plane.
  • the finished roll with the first central drive and the winding shaft guide is moved in the direction of the deposit arms of the roll dispenser.
  • This movement is achieved by drives on the winding shaft guide.
  • the central drive decouples from the winding shaft guide and is permanently coupled to its end position, for example to the machine housing wall.
  • the central drive continues to drive the lap.
  • the contact roller unit moves back a little, away from the winding position.
  • the second central drive on the opposite side of the first central drive, decouples from its parking position and couples with the winding shaft guide.
  • the winding shaft guide and the second central drive coupled to it move in the direction of the contact roller unit to the winding position.
  • the winding position does not represent a fixed location, but is the position in which the central drive, in cooperation with the contact roller, winds the web-shaped material onto the roll. As the roll diameter increases, the position moves further and further on the guides in the direction of the roll dispenser.
  • the new winding shaft is now moved with the winding shaft transport unit from the first parking position further upwards in the direction of the winding plane into a second parking position.
  • the lower separating device is swiveled into the course of the film as a lifting device and the film web is lifted to make space for the new winding shaft.

Depending on how they are carried out, these steps run very quickly or at the same time.
  • the film is now wound onto the new winding shaft by the second central drive.
  • the remaining web of material is wound onto the finished roll by the first central drive.
  • the first central drive is decoupled from the finished lap and the finished lap is released from the winder via the roll dispenser.
  • the roll dispenser can be hydraulic.

  • the winder can also be designed for winding with a gap, in which case the contact roller does not have to be pressed against the winding.
  • Such a winder enables permanent winding without the winding conditions changing due to undesired external disturbances.
  • the material web is wound from the start under defined conditions such as web tension and contact pressure and does not experience any interference from external influences, as they otherwise occur at pre-winding points, due to the transfer of the lap from the pre-winding point to the winding point.
