Definitions

  • the invention relates to a winding device, in particular for a slitter winder, for winding up and unwinding a material web to or from a winding roll with a support device that can be placed on the circumference of the winding roll.
  • the paper web is wound up into winding rolls, possibly after passing through a slitter.
  • a winding core or a cardboard winding tube is often used as the starting point for the winding roll.
  • This winding tube has insufficient rigidity, especially in the case of wider winding rolls, so that the winding roll with increasing diameter and thus increasing weight in the middle begins to sag or sag if it is only held on the roll core, ie at the center of the winding roll, during winding.
  • one is therefore more or less forced to support the winding roll on the circumference in order to reduce or avoid bending, as was recognized in EP 0 289 776 B1.
  • the main focus is on unwinding. The problem of supporting the roll with great weight also arises there.
  • the weight of the winding roll increases with increasing diameter. Accordingly, with increasing diameter, the weight with which the winding roll rests on the support device increases, and thus the contact pressure.
  • this contact pressure is one of the factors that determine the hardness of the winding. The larger it is, the greater the winding hardness.
  • this phenomenon is undesirable. Rather, one would like to achieve the opposite winding hardness curve over the diameter of the roll, i.e. the roll should be wound harder in the area of the roll core than on the circumference.
  • DE 42 14 713 A1 shows the use of a belt which is guided over three support rollers which are arranged in a triangle, the base of which points upwards in the direction of gravity. Accordingly, between the two upper support rollers there is a free length of the belt on which the winding roller rests. If you influence the tension of the tape accordingly, then the tape lies in a partial area on the circumference of the winding roll. The weight distributed accordingly on a slightly larger area, so that the contact pressure is lower.
  • US 3 889 831 A shows a device for winding a winding roll, in which the winding roll rests on several support rolls.
  • the idlers are combined in pairs. Each pair is attached to a lever, which in turn is articulated to a bracket.
  • Each carrier has two pairs of rollers and is itself articulated on a machine frame. The machine frame has two such supports. The individual idlers can therefore lie on the circumference of the winding roll for any diameter of the winding roll.
  • US 2 134 656 A shows a further winding device in which a winding roll rests on two support rolls.
  • the idlers are mounted in a stand that consists of two parts that are hinged together.
  • the hinge point between the two parts is connected via a rigid coupling to the axis of the winding roller, so that the distance between the two carrier rollers increases with increasing diameter of the winding roller.
  • DE 44 27 877 C1 shows a winding device with a winding roll for web-shaped material, in which the winding roll rests on a compressed air cushion that is generated between a support device and the winding roll.
  • the invention has for its object to reduce the influence of weight on the quality of the winding roll.
  • the support device has a plurality of rotatable rolling elements arranged in the circumferential direction in the manner of a chain, the axes of rotation of which run essentially parallel to the winding axis and which are articulated to one another transversely to the axes of rotation.
  • a "roller carpet” is therefore used as the support device.
  • This roll carpet provides a variety of support points for the winding roll. Since the rolling elements are connected to one another in an articulated manner along the circumferential direction, it is possible to continuously adapt the support points to the diameter of the winding roll, which changes during winding. Accordingly, the weight of the winding roll is distributed over the many support points, i.e. on the many rolling elements, so that in each individual nip (between the winding roller and the rolling element) there is a correspondingly reduced surface pressure, which makes it possible to reduce the influence of the weight and to avoid uncontrolled changes in the winding hardness.
  • the fact that the individual rolling elements can be relatively closely adjacent in the circumferential direction results in only short free path lengths which do not further interfere. Rather, the support device can provide a clearly defined support force relatively well.
  • the support device preferably has at least one end in the circumferential direction of a tensioning device which acts essentially counter to the direction of gravity.
  • the tensioning device ensures that the support device is held with the necessary tension against the circumference of the winding roller in order to absorb the weight. With the tensioning device it is possible to effect that the desired part of the circumference of the winding roll is acted upon accordingly with the support device.
  • the tensioning device preferably has a lifting device which is articulated on a base.
  • the lifting device initially has the advantage that it can act against the direction of gravity.
  • the winding roll is raised, so to speak.
  • the articulated support of the lifting device which can be designed, for example, as a hydraulic lifting cylinder, makes it possible for the supporting device to be able to adapt to the changing diameter of the winding roll.
  • the end at which the tensioning device is arranged can then be moved not only in the vertical direction but also in the horizontal direction.
  • Both ends are preferably provided with a tensioning device. This allows the tensioning device to be adapted even better to the circumference of the winding roll.
  • the necessary tension of the "roller carpet” can also be generated by a tensioning device that also acts in the horizontal direction.
  • the corresponding tension elements e.g. hydraulic cylinders, can be articulated here to avoid bending moments due to increasing roll diameter.
  • the center (and adjacent areas) of the roller carpet change their vertical position with the diameter of the roller more than the ends. With a larger diameter, the roll automatically dips deeper into the support device, so that the number of contact surfaces practically automatically adapts to the roll diameter of the winding roll. You can also combine horizontal and vertical clamping devices.
  • This tensioning device can either spread two stands on which the ends of the support device are attached, or it pulls the two ends of the support device apart.
  • the rolling bodies can be designed as continuous rollers. This is a Technically very easy to implement design in which the rollers extend practically over the entire axial length of the support device.
  • the rolling elements are preferably designed as wheels, with several wheels having a common axis of rotation and a distance between individual wheels remaining in the axial direction.
  • the continuous rollers are divided into several axial sections.
  • the axis of rotation can, but need not, be provided as a continuous structural part. It is sufficient if the centers of several wheels lie on an imaginary straight line around which the wheels rotate.
  • the term "wheels" is used here as a distinction to the continuous "roles”.
  • the wheels can also have a greater axial extent than the diameter. But you don't have to.
  • the wheels preferably have a diameter in the range from 100 to 300 mm and an axial extent in the range from 25 to 100 mm.
  • Training with the wheels has a special advantage. This is because a connection can be made between axes of rotation at least at a distance. This results in a higher rigidity of the support device in the axial direction. The risk that the support device will sag in the axial direction will then be reduced.
  • the wheels of adjacent axes of rotation are arranged offset to one another in the axial direction, the wheels of one axis of rotation projecting into the distances between the wheels of the adjacent axis of rotation.
  • the wheels are preferably fastened to carrier strips which are arranged one behind the other in an articulated manner in the circumferential direction.
  • the axes of rotation simultaneously form the articulated connections between the carrier strips.
  • the carrier strips lead to a relatively high degree of rigidity in the axial direction.
  • Each wheel is preferably supported on both axial sides. This increases the resilience.
  • the rolling bodies are preferably connected to one another in the circumferential direction of the winding roll by an elastic carrier. Then, if the ends of the support device do not follow the change in the diameter of the winding roll or do not follow them sufficiently, there is a greater tension with a larger roll diameter and thus a greater load capacity.
  • At least one rolling element advantageously has a fan arrangement.
  • the roller bodies rotate, the peripheral speed of the roller bodies being at least approximately equal to the peripheral speed of the winding roller. If you now provide the rolling element with a fan arrangement, for example with baffles that act in the manner of a fan, the resulting air flow can be used for cooling. With the flexing work unavoidable when changing This is because heat is generated which can be dissipated elegantly with little additional effort.
  • this drive can relieve the drive of the winding roll. For example, it is possible to introduce a drive power that is sufficient to rotate the rolling elements.
  • the corresponding roller body can also be driven at a different peripheral speed than the winding roller, so that one can influence the winding hardness in this way.
  • the support device preferably has an elastic surface.
  • the contact points between the winding roll and the rolling elements are thereby widened, which in turn leads to a lower surface pressure.
  • the surface of the winding roll is protected.
  • the rolling elements have an elastic surface.
  • the winding roll rests on many elastic support points, which increases the contact area.
  • an almost frictionless movement on the support device is still guaranteed.
  • the rolling elements have chambers filled with air or foam under their surface. This is particularly advantageous if wheels are used as rolling elements. Conventional rubber tires can then be used as wheels, which are inflated. These are then elastic enough to allow the winding roll to be applied gently, which results in the desired low surface pressure Has. In some cases it will also be sufficient if the load-bearing capacity is achieved solely through the rigidity of rubber wheels.
  • the support device advantageously engages the winding roll symmetrically. This leads to a well controllable force distribution. Particularly when the roll diameter increases, no measures have to be taken to compensate for the forces exerted by the support device, which do not only act in the direction of gravity.
  • the invention also relates to a winding method for winding or unwinding a material web to or from a winding roll, in which the winding roll is rotated with a stationary axis and is supported on the circumference from below at least above a predetermined roll diameter.
  • a band-like or chain-like support device is stretched horizontally for support, the ends of the support device being moved vertically at a speed which is less than the change in diameter of the winding roll.
  • the winding roll has a weight that requires support. From this point in time at the latest, it is necessary for the support device to support the circumference of the winding roll.
  • the support device is tensioned for support. As the diameter of the winding roll increases, the winding roll sinks deeper and deeper into the support device. This is caused by the ends of the support device be lowered more slowly as the winding roll grows. This has two effects: Firstly, the vertical support force is increased because the horizontal tension increases due to the vertical pressing of the winding roller. On the other hand, the curvature of the support device automatically approaches the radius of the winding roll. There is an automatic adjustment of the support surface of the support device to the peripheral surface of the winding roll.
  • the support of the winding roll thus grows dynamically, so to speak (or decreases dynamically when the winding roll is unwound). It is achieved in this way that the contact pressure exerted by the support device on the winding roller always remains to an acceptable level despite the stationary mounting of the axis of the winding roller.
  • the lowering of the ends takes place more slowly than the increase in the diameter of the winding roll, the desired tension is maintained and even increases.
  • the ends of the support device are held in a vertical position below the predetermined diameter of the winding roll. As long as the diameter of the winding roll has not yet been reached, the support device does not have to take action. As soon as this diameter is reached, the support device can be brought into contact with the winding roll.
  • the predetermined diameter of the winding roll depends largely on its width, but is generally 800 mm or less. Experience has shown that with a radius of 400 mm the roll weight is so high that support is necessary.
  • the ends of the support device are preferably held stationary at a height which is 45% of the predetermined diameter away from the height at which the axis of the winding roll lies. This takes into account the fact that the support device sags somewhat, even if it is stretched horizontally. For this reason, the ends of the support device (“ends" always mean those lying in the circumferential direction of the winding roll) are arranged somewhat higher, so that the winding roll practically automatically meets the support device when the predetermined diameter is reached.
  • the support device is designed as a "roller carpet", which has been described above.
  • partial webs 5', 5 "of a material web 5 are wound into partial web rolls 6.
  • the partial web roll 6 is in one in the left winding station 1 shown relatively late stage of the winding process, ie it has almost reached its final diameter.
  • the right winding station 1 ' shows the start of a winding process Length of the winding roll 6) leads to the risk of sagging of the winding roll 6 in the axial center, which in turn leads to uneven and thus undesirable winding results.
  • the partial webs 5 ', 5 are guided through a nip 8 between a pressure roller 9 and the winding roller 6.
  • the pressure roller 9 can be moved by means of a slide on a base 7, for example a machine frame Known measures are achieved that the pressure roller 9 exerts a certain contact pressure on the winding roller 6 or the winding tube 4 at the beginning of the winding process in order to adjust the winding hardness.
  • a support device 11 is provided, which in FIG Side view and is shown in more detail in FIG. 3 in plan view, FIG. 3 only showing half of the support device.
  • two plungers 15 are provided, which are connected to one another by a carrier 22.
  • Several wheels 23 are provided as support elements.
  • the wheels 23 are arranged on axes of rotation 24, 25 with an axial spacing from one another, each forming a gap 26.
  • the wheels 23 of adjacent axes of rotation 24, 25 are offset from one another in the axial direction, so that the wheels of an axis of rotation 25 into the gap 26 between the wheels 23 of the other axis of rotation 24 can protrude.
  • the support device 11 ' is shown in solid lines for a smaller diameter of the winding roller 6 and with dashed lines for a larger diameter of the winding roller 6.
  • the axes of rotation 24, 25 form articulation points for the connection of strips 20 which are connected to one another in the manner of a chain running in the circumferential direction. These strips 20 are not only provided in the region of the axial ends of the support device 11, but on both axial sides of each wheel 23, so that on the one hand each wheel 23 is well supported and on the other hand there is a relatively high degree of rigidity in the axial direction.
  • the axes of rotation 24, 25 can practically not sag because they are supported in their axial center.
  • the axes of rotation are preferably held non-rotatably, while the wheels 23 are rotatably supported on the axis of rotation by means of bearings 27.
  • the wheels 23 can now have different designs.
  • Fig. 3 three forms are shown as an example.
  • the wheel 23A has air chambers 28, so it can be inflated and thus pressurized so that it shows an elastic behavior that approximates that of a car tire.
  • the wheel 23B is made entirely of plastic, which has a certain elasticity, so that the circumference of the wheel 23B can be slightly depressed by the winding roller 6 in order to widen the bearing surface.
  • the wheel 23C has chambers filled with a plastic 29, so that it also has a predeterminable stiffness.
  • the wheels 23 are compressible, even if only to a small extent, then a certain amount of heat is generated by the continuous flexing work.
  • at least some wheels can be provided with ventilation devices 30, for example a guide plate arrangement on their hub 31, which acts in the manner of a radial fan. Since the wheels turn anyway during operation, this rotary movement can be used to generate a cooling air flow that dissipates the heat.
  • all wheels can also be equipped with such ventilation devices 30.
  • the ventilation devices 30 can also be arranged on both axial ends of the wheels 23. It can be seen relatively well that an air flow generated in this way is blown directly onto the peripheral surface of the adjacent wheel of another axis of rotation.
  • the support device 11 in FIG. 4 represents an alternative to the embodiment according to FIG. 3. It has a series of rolling bodies which are designed as rollers 13 which run continuously over the axial length of the support device. A roller 13 'is driven here. All roles have a surface that has a certain compressibility (not shown). It thus forms an elastic surface of the support device 11.
  • the individual rollers 13 are connected to one another by strips 20 made of a strip steel or a thick sheet metal, the axes of rotation 21 of the rollers 13 simultaneously forming hinge points for the strips 20.
  • the strips 20 are thus articulated to one another in the circumferential direction.
  • the support device 11 can therefore wrap around a part of the circumference of the winding roll 6, as is shown in FIG. 1 for the winding station 1.
  • the strips can also be formed from a stable, elastic material.
  • Both ends 14 (in the circumferential direction) of the support device 11 are each connected to a plunger 15 of a lifting cylinder 16.
  • the lifting cylinders 16 are supported via articulation points 17 on a base 18, for example the floor. You can therefore incline, as a comparison of the winding stations 1 and 1 'shows.
  • the two ends 14 of the support device 11 are raised, so that the support device practically hugs the circumference of the winding roller 6 like a band.
  • the area against which the support device 11 rests moves downward in the direction of gravity. Accordingly, the plunger 15 of the lifting cylinder 16 retract.

As the diameter increases (shown in dashed lines), the winding roll is increasingly immersed in the support device 11 '. The contact area also increases automatically. If the length of the support device 11 'in the horizontal direction is kept the same, then the tension and thus also the vertically acting restoring force increases, so that the winding roller 6' is supported even better.
  • the roller 6 ' is shown with a solid line when it has reached a diameter from which support by the support device 11' is necessary. It is exaggerated for clarification that the support device (with the solid line) has a horizontal course. In reality, however, it will sag somewhat due to its own weight. Accordingly, you arrange the ends, So the inner hinge points of the cylinders 16 ', so that they are about 10% higher (based on the radius of the winding roller 6') than shown.
