Definitions

  • the invention relates to a roll winding device two carrier rollers that hold a changing bed for one Form winding roll, and a compressed air support device, which a pressure chamber arrangement with end face sealing elements having.
  • the invention is intended to be exemplified in the following with the aid of Paper rolls are described. But it is not open limited this application.
  • paper webs In one of the last manufacturing steps, paper webs usually cut to the correct width and then rolled up in rolls before packed and shipped.
  • the winding cores on in contrast, which are wound up the paper rolls to those used during paper production Drums only a relatively low stiffness and Load capacity. They are often designed as cardboard tubes. This means that the paper rolls at Wikkein are usually supported by support rollers. This is particularly pronounced when the winding device is designed as a roller winder. Here the roll rests on carrier rollers without additional Attack holding forces on the core. But also with a back-up roller roller with additional holding means there can be an attack on the roll core on a roller.
  • the Carrier rollers used. Below is the support roller Sealing plate or a sealing box arranged.
  • the paper roll itself serves as a seal.
  • the seal On the face of the paper roll is the seal the current constructions (see e.g. DE-A-4110047) made in that a sealing plate with adapted to the contour of the changing bed Shape as close as possible to the front of the Paper roll is positioned.
  • the sealing plate would in such cases also wear out very quickly. For this reason, leave a distance of several millimeters between the face of the paper roll and the sealing plate. It is obvious that there is air through this gap escapes in considerable quantities.
  • the invention has for its object the air consumption small injury.
  • This task is done with a roll winding device of the type mentioned in that at least an end sealing element one with the circumference the sealing roller arrangement interacting with the winding roller having.
  • sealing Location namely the end face of the winding roll
  • relocated the location of the seal on the peripheral surface of the Winding roll This has several advantages.
  • the circumferential surface of the winding roll is generally significant smoother than her face. Accordingly, can one the sealing diaphragm arrangement with an essential Position a smaller distance from the circumferential surface of the winding roll. For example, you can set a minimum distance of only 0.5 mm. On the other hand you can the axial extent of the sealing diaphragm arrangement somewhat choose larger, so that this results in a greater flow resistance for the escaping air is formed.
  • sealing diaphragm arrangement is not intended to be plate-like Be limited. It basically includes everyone Body or parts that match the circumference of the winding roll interact and thereby escape the air prevent or at least make it difficult at the end faces.
  • the Winding roller acting seal With reasonable effort practically impossible to get a hermetic seal achieve. This is because, for example, that here made a seal against three moving parts must be, namely opposite the two support rollers and the winding roll.
  • the sealing diaphragm arrangement and are preferably at least a support roller height adjustable relative to each other. This takes into account the fact that the diameter of the winding roll changes during winding. There the support rollers a constant distance relative to each other the change in diameter leads to that the winding roll keeps getting out of the changing bed lifts out, i.e. less with a larger diameter plunged deep into the changing bed. If the seal assembly is adjustable in height, then you can despite this change in the sealing geometry always the desired maintain a small sealing gap. this applies even if the axes of the support rollers are not in the same level or the diameter of the Carrier rollers are uneven.
  • the sealing diaphragm arrangement has a sealing panel with a variable shape.
  • the Ratios of increasing diameter Take into account. If the diameter of the winding roll enlarged, then a larger one is created on the front "Window" through which air could escape. you can now change the shape of the sealing panel continuously or from time to time to adjust so that you can this window as possible covers well.
  • the width of the Sealing diaphragm is changeable. With increasing diameter of the winding roll move the support points of the winding roll on the idlers away from each other. If changed the width of the sealing panel, then you can Follow the contact points of the winding roll on the support rollers and thereby keep the opening through which the Air could escape.
  • the vertical distance from the ends to the center of the Sealing screens is changeable.
  • the Sealing diaphragm the cross section the shape of a flat V have, the opening angle with increasing Roll diameter increases.
  • the shape of the sealing diaphragm is preferably a function the height setting can be changed.
  • Carrier roller geometry results in the shape of the to be sealed Opening depending on the increasing winding roll diameter.
  • the growth of the winding roll diameter has two episodes, as I said. For one thing, it wanders lowest point of the winding roll circumference steadily upwards, So out of the changing bed. On the other hand they hike Support points of the winding roll on the support rollers Outside.
  • the sealing panel as close as possible to the circumference of the winding roll to hold, you can keep the information on the "Altitude", ie over the vertical position of the Sealing screen, use at the same time, also for specified a specific winding roll diameter Shape, for example a predetermined width.
  • the sealing panel from several, against each other movable parts is formed. If you look at the parts moved relative to each other, the shape of the Change the sealing panel in a simple way.
  • the parts are relative are displaceable or pivotable relative to one another. With the width can be shifted, for example change the sealing panel. The only requirement is that between parts of the sealing panel there is some overlap so that when moving no new openings are formed.
  • each part is opposite one Lifting device in a first guide and opposite a fixed bracket in a second guide is.
  • the first Leadership allows the movement relative to the lifting device to.
  • the second guide controls the sideways movement.
  • At least one of the two guides designed as a linear guide. Leave linear guides easy to manufacture. The danger that the part jammed or jammed, is relatively small.
  • two parts of the sealing panel designed as a pivot lever are. Even with such swivel levers it is possible the changing altitude of the lowest point of the To follow the circumference of the winding roll. Are swivel levers relatively easy to control.
  • each pivot lever extends approximately from one support roller to the other and has a stationary pivot axis at one end.
  • the two swivel levers together cover at least approximately the entire width of the changing bed. With width is the distance between the two support rollers meant. Cross over due to the arrangement of the swivel axes the two swivel levers when lifting, so that the formed by both swivel levers together, common lowest point the circumference of the winding roll can follow.
  • the sealing diaphragm arrangement is preferably on one End wall of the pressure chamber assembly attached.
  • This Front wall can already cover most of the cross section cover that freely between the idlers remains.
  • the front wall can therefore extend up to one position extend up to which the winding roll at her smallest diameter to be supported, as a rule about 800 mm.
  • the sealing diaphragm arrangement must then only the larger roll diameter cover the resulting cross section.
  • the front wall offers In addition, it is also an inexpensive fastening option.
  • the end wall is preferably parallel to the support rollers traversable.
  • the Front wall moved away from the winding roll. Only at; only when a larger diameter at which the lowest point the winding roll is lifted out of the changing bed far enough the front wall is provided. First to this At the same time, however, pressure is also applied and accordingly is only a seal at this time necessary.
  • the sealing diaphragm arrangement preferably has a Tracking device with a drive and a sensor for the position of the winding roll.
  • the drive serves to raise the seal assembly so that it the changing position of the winding roll circumference consequences. So that the sealing panel arrangement always
  • the winder roll sensor can stay as close as possible to the circumference intended. He reports back to the drive if the seal assembly is on one has approximated the predetermined value to the circumference. If this state is reached, then the drive interrupts the further lifting of the sealing panel arrangement.
  • the winding roll sensor can be used in several different ways Be trained types. You can use it, for example, without contact let work, e.g. pneumatic, capacitive, inductive, optical or with a laser scanner. In In this case, the Drive possible.
  • a roll winding device 1 of which only for the Explanation necessary section is shown has a first support roller 2 and a second support roller 3, which form a changing bed 4 between them.
  • a winding roll 5 In the winding bed is a winding roll 5.
  • This winding roll is shown with a circumferential line 6 for one smaller diameter and a second circumference 7, which results when the diameter of the winding roll has increased.
  • the second circumferential line 7 has less curvature.
  • the changing bed 4 is not shown in detail also sealed down.
  • an air supply port (not shown) provided, via which compressed air is fed into a room can be that of the support rollers 2, 3, the Winding roll 5 and the end walls 8 (on the opposite Side of the winding roll is also located such an end wall) is limited.
  • the end wall 8 ends at the top, i.e. on the of the winding roll 5 adjacent side, at a height up to which the Circumferential line 6 of the winding roll 5 is sufficient. This circumference arises when the winding roll 5 a Has reached diameter, from which a compressed air support necessary is. This diameter is in many cases in the order of about 800 mm.
  • winding roll 5 has a diameter that is represented by the circumferential line 6, then lies them at a first point 9, more precisely along a axially parallel line 9, on the support roller. If the diameter has increased so that the winding roll 5 has the circumferential line 7, then shifts the edition becomes a line 10. The same applies naturally also for the other carrier roller 3.
  • the end wall 8 covers, as stated, the largest part from the front of the clear space, which through the Carrier rollers 2, 3 and the winding roller 5 is formed. It there remains a small opening 11, but in practice is not critical. A hermetic seal of this In practice, space is anyway with reasonable effort not possible and as long as the leak in certain Limits remain, also not necessary. critical however, would be the enlargement of the opening itself when changing the circumference of the winding roll 5 results. This opening could then take on sizes through which a lot of air escapes.
  • the seal panel assembly has a carrier 13, which is by means of a lifting cylinder 14 can be raised from a dashed line position 15 shown in the with solid Line represented position.
  • a sealing diaphragm 16 is arranged on the carrier 13, which interacts with the circumference of the winding roll 5.
