Definitions
- the invention relates to a winding device for winding a web-shaped material according to the preamble of claim 1.
- Web-shaped material for example plastic film
- a web production device for example in an extrusion device
- finishing machines include printing machines, tube making machines, and many other machines
- Other materials, such as paper, are also wound in a winder and fed in the form of coils to a further processing machine.
- these windings are formed by winding the web-like material onto a winding core. Before the web-shaped material reaches this winding core or the winding on which already web-shaped material is wound, it is guided over a web guide roll.
- This web guide roller can be arranged at a small distance from the winding core or to the winding (so-called “gap winder") or press the web-shaped material directly to the winding core or the winding
- said web guide roll is typically the last roll over which the sheet material is passed before it reaches or while it reaches the winding core or package.
- the winding is often associated with a pressing element which can be adjusted to the winding.
- This pressure element is usually designed as a pressure roller.
- the mechanism which is used to adjust the pressing elements to the winding comprises slides in which the pressure roller or the pressure element is mounted at both ends, the slides being displaceably arranged on mutually parallel rails. These rails are attached to walls, which also carry the hubs.
- the carriages supporting the pressure rollers are moved or removed by means of suitable adjusting means, such as a piston-cylinder unit, in the direction of the winding core.
- the object of the present invention is to propose a winding device in which the mechanism, which serves to adjust the pressure element to the winding, requires less space.
- the pressure element is mounted at both ends in a Hebelarmcru forming lever arms.
- This pressure element may be a pressure roller, which is rotatably mounted in this Hebelarmcru.
- the lever arms are rotatably mounted in the walls in which the winding core is mounted. Since the bearing points of the pressure element in the lever arms and the bearing points of the lever arms in the walls do not coincide, the pressure element is ultimately pivotable about the bearing points of the lever arms. In this way, no rails are needed for the movement of the pressing element, but only lever arms which are rotatably mounted in one point. For this reason, the winding device according to the invention can be constructed much more compact than a winding device according to the known prior art.
- turret winder Of crucial importance is the question of space requirements in so-called turret winder.
- the winding core and the mechanism for adjusting the pressing element are attached to disks or plates which are rotatably mounted in the machine frame.
- At least one second winding core and at least one further mechanism for adjusting pressure elements are respectively mounted or fastened to these disks or plates.
- a turret winder after a wound has been wound up, serves the rapid winding of the new web start formed by a cut on the second winding core.
- a particularly advantageous embodiment of a winding device according to the invention therefore comprises the mentioned features of a turret winder.
- the space requirement of the mechanism for adjusting the pressing element directly affects the size of the discs or the plates and also the drive power that is necessary for their rotation in the machine frame.
- the pivoting range of the lever arms is dimensioned so that a pressure roller can alternatively come into contact with two winding cores.
- the pressure roller which does not have its own rotary drive, can be set in rotation by a rotating winding core.
- the pressure roller can be accelerated before it touches the winding.
- An acceleration of the pressure roller through the winding, on which already web-shaped material has been wound up, can lead to damage to the web-like material.
- the winding cores are assigned drive means, which act on these with a torque.
- Each winding core can be assigned its own drive.
- two or more Winding cores are driven by a drive, wherein a releasable coupling between the drive train and the winding core is provided in order to be able to stop the winding for the purpose of Abtransports while another winding core is further wound.
- the invention also relates to a method for continuously winding a web-shaped material to wind according to claim 9. Further method steps, which belong to the method according to the invention, are described below in the context of the present description.

- FIG. 1 shows a winding device according to the prior art.
- the web-shaped material 2 which is supplied in the direction A of the winding device, guided over the contact roller 3.
- the contact roller 3 is attached to the winding 4, which is wound on a winding core 5, employed, so that the run of the contact roller 3 web-like material is placed on the winding.
- a pressure roller is employed on the winding 4, which presses the uppermost layer of the sheet-like material 2 with pressure to the winding 4 to prevent air pockets. Due to the strength of the pressure, the so-called winding hardness can be determined.
- the winding core 5 is rotatably mounted at both ends in disks, of which only the rear disk 7 is shown.
- the discs are in turn rotatably mounted in the machine position not shown.
- the contact roller 3 is also mounted on the machine frame via elements that allow movement of the contact roller 3 relative to the winding core 5.
- the pressure roller 6 is mounted on slides not shown in guides 8, wherein the guides are attached to the discs. With the help of piston-cylinder units or other suitable drives the pressure roller 6 can be moved relative to the guides and thus relative to the winding core 5.
- a second winding core 9 and further guides 10 are mounted or fastened in the disks mentioned.
- the guides 10 also carry in this slidable carriage, a second pressure roller 1 1, which is associated with the winding core 9.
- the winding core 9 By rotating the disks 7, the winding core 9 can be pivoted in the direction of the contact roller, so that this winding core 9 comes into contact with the web-shaped material.
- the winding 4 By the rotation of the discs, the winding 4 is pivoted away from the contact roller 3.
- the sheet-like material can be cut by a cutting device, not shown, so that a new web beginning arises, which can be determined by suitable means on the winding core 9.
- the old winding 4 can now be removed from the winding device and replaced by an empty winding core. In this way, without the winding device would have to be stopped in order to change the winding core, a new winding.
- FIG. 2 shows a winding device 1 according to the invention during the winding operation.
- the pressure roller 6 is mounted in a pair of lever arm, of which only the rear lever arm 12 is shown in the apparatus according to the invention.
- Both lever arms of the Hebelarmcrues are connected to each other via suitable coupling elements, such as connecting rods, so that the axis of rotation of the pressure roller is always parallel to the axis of rotation of the winding core.
- a sprocket or sprocket segment are attached to each disc 7, on which roll off gears mounted on a coupling shaft. Between sprocket or - segment and gears of the coupling shaft further gears can be provided.
- the coupling shaft can be guided through an axial bore of the pressure roller 6, 1 1. If now one of the two lever arms is acted upon by a torque, the coupling shaft rotates, and transmits a torque to the respective other lever arm, wherein the end of the coupling shaft, which is rotatably mounted in the other lever arm, also on a ring gear or segment rolls. In this way, an exact same angular position of the lever arms is guaranteed. This situation will be explained below with reference to FIG. 9.
- the lever arm 12 is mounted on a bearing 13 in the disc 7.
- the axis of rotation of the pressure roller 6 is parallel to the axis of rotation of the bearing 13. Both axes are not aligned. The same applies to everyone else Lever arms, which are shown in this and the following figures, but also for the lever arms, which are not shown.
- lever arms for example, by a drive motor, on the rotor axis, a pinion is attached and attached.
- This pinion meshes with a gear or a gear segment, which is fixed to a lever arm of the Hebelarmcrues and whose axis of rotation is aligned with the axis of rotation of the bearing 13.
- an air motor is preferred, which is very compact and lightweight. This will be discussed further below in the description of FIG.
- the pressure roller 1 which is mounted and driven analogously to the mounted in the lever arm 12 pressure roller 6 in the lever arm 14, is shown in the operating situation shown in Fig. 2 in a pivoted-off from the winding core 9 position.
- FIG. 3 shows the winding device 1 according to the invention already shown in FIG. 2 after the disks have been rotated so far that the winding core 9 assumes the original position of the winding core 5.
- the web-shaped material 2 is wound in the situation shown initially further on the winding, wherein the web-shaped material 2 also passes over the pressure roller 1 1.
- a severing of the web-shaped material is carried out by a separating device, not shown.
- the resulting tail is further wound on the winding 4.
- the web beginning caused by the separation of the sheet-like material is fixed to the winding core 9 by a suitable measure, such as fixing by means of an adhesive.
- the web-shaped material 2 is now wound on the winding core 9.
- the resulting tail has reached the old winding 4, so that the pressure roller 1 1 is no longer in contact with the web-shaped material 2.
- the lever arm 14 is pivoted in the direction of this winding core and thus the pressure roller 1 1 to the Employed hub.
- the winding device illustrated in FIGS. 2 and 3 is used in particular in the case of slow-running sheet-like material.
- the reason for this is to be found in that the pressure roller 1 1, which is in its position shown in FIG. 2 at rest or even rotated from the previous winding on the winding core 9 against the web running direction of the web-like material in rotation or must be placed in opposite rotation as soon as it touches this.
- a high transport speed of the material 2 would make a high acceleration of the pressure roller necessary and thus require a large force.
- the forces acting thereby could lead to damage of the web-like material.
- the limit at which the described device can still be used without damaging the web-like material lies at a transport speed of 150-200 meters per minute, although this limit may also depend on the material properties.
- a winding device which is also suitable for winding fast running material is shown in Figures 4 to 8.
- FIG. 4 schematically shows a further embodiment of the winding device 1 according to the invention.
- This winding device substantially coincides with the winding device shown in FIG. 2, but the device shown in FIG. 4 comprises additional deflection rollers 15 and 16.
- These deflection rollers 15 and 16 are rotatably mounted in holders which are attached to the discs.
- the number of pulleys is not limited to two, it may be provided a plurality of pulleys. In FIG. 4, only the holders 17 fastened to the rear disk are shown.
- the function of the deflection rollers 15, 16 will become apparent from the following description of Figures 5 to 8, in which the winding core changing operation is illustrated.
- FIG. 5 shows the winding device 1, in which now the lever arm 14 has been pivoted in the direction of the winding core 9, so that the pressure roller 1 1 is in frictional contact with the winding core 9.
- the winding core 9 is now rotated by a drive in rotation, whereby the pressure roller 1 1 is set in rotation.
- the rotational speed is chosen so that the peripheral speed of the pressure roller 1 1 substantially corresponds to the transport speed of the web-shaped material.
- FIG. 6 in comparison to FIG. 5, first the contact roller 3 is displaced relative to the disk 7, so that it is no longer in contact with the winding 4. Subsequently, the discs were rotated through an angle of approximately 90 °. After this rotation angle, the guide roller 15 almost comes into contact with the web-shaped material 2.
- the guide roller 15 may, depending on the material, have an external Vorbevanter. But it can also be rotated by the web-shaped material in rotation.
- the pulley has a small diameter and is made of a lightweight material, so that its acceleration only one compared to the acceleration of a pressure roller low torque must be applied. The guide rollers can therefore be used at high transport speeds of the web material.
- FIG. 8 shows the operating situation, according to which the web-shaped material 2 has been severed by means of a separating device.
- the resulting tail was wound on the winding 4.
- the newly created web start was again set on the new hub 9, so that At this point a new winding is created.
- the lever arm 14 was pivoted in the direction of the winding core 9 and brought in this way the pressure roller to the winding core 9 and to the new roll in abutment.
- FIG. 9 shows the section IX - IX drawn in FIG. 3.
- both discs 7 can be seen, in which both lever arms 14 are rotatable about the symbolized as a dotted line axis of rotation 20.
- a sprocket or a sprocket segment 21 is attached in each case. With each of these sprockets or sprocket segments 21 meshes each have a gear 22, both gears are rotatably connected to a coupling shaft 23.
- the coupling shaft 23 is rotatably mounted in the lever arms 14 via suitable bearings 24, such as ball bearings.
- the pressure roller 1 1 itself is rotatably mounted on the coupling shaft 23 by means of rotary bearings 25. As already described, the pressure roller is not driven. So it is freely rotatably mounted.
- gears or gear segments 26 are attached to the lever arms. With these gears or gear segments 26 mesh pinion 27 which are rotatably mounted on the drive shafts 29 of drive motors 28.
- drive motors which are advantageously designed as air motors are attached to the discs 7.
