Definitions

  • the invention relates to a roll winding device, especially for a slitter winder, with a Roller carrying device and with a pneumatic Pressure relief device.
  • Such a roll winding device is for example known from DE 195 24 905 A1.
  • the invention is intended to be exemplified below with reference to Paper rolls are described. But it is not open limited this application.
  • paper webs usually cut to the correct width and then wound up in rolls before packed and shipped.
  • the winding cores on in contrast which the paper rolls are wound up to those used during paper production Drums only a relatively low stiffness and Load capacity. They are often designed as cardboard tubes. This causes the paper rolls to curl 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 backup roller roller with additional holding means attack the roll core, there is a support on a roller. When the paper rolls are bigger and heavier the support line forces of the paper roll on the roller or rollers relatively large, which is the disadvantage has that the winding hardness is increased. This can cause the roll to burst later. To relieve the rollers and reduce the line force can a pneumatic pressure below the Role are generated so that the role is at least partially resting on an air cushion.
  • the invention has for its object the air consumption to lower.
  • This task is done with a roll winding device of the type mentioned in that the Pressure relief device several blow boxes with outlet nozzles has on its top, the Blow boxes hinged in pairs on a swing arm on which they are parallel to the roller axis extending tilt axis are tiltable.
  • the outlet nozzles are preferably symmetrical to one Plane arranged perpendicular to the surface stands and runs through the tilt axis. This will ensured that the gap on both edges of the Blow boxes, based on the circumferential direction of the roll, largely remains the same. Should the gap on one Enlarging the edge, more air escapes here, so that the Pressure here decreases and becomes less than the pressure the other edge. The box will then be about Swing the tilting axis back again until it does equilibrium is reached on both edges. Because of the symmetrical design of the boxes is then reached a state of equilibrium when both edges are equally far from the circumference of the roll.
  • the blowing nozzles are advantageously at least two parallel rows arranged parallel to Tilt axis run. This configuration has manufacturing technology Benefits. Leave the parallel rows generate easily and check for symmetry. With a "chaotic" hole pattern, this would be with more effort.
  • the focus of the blow boxes is preferably in Direction of gravity below the tilt axis. If the Roll is lifted, they automatically swivel in a position in which the top is vertical lies horizontally above. When a new role is launched the tilt angle is at the latest at the Pressurization automatically.
  • blow boxes of a rocker are preferably symmetrical to a penetrating the second tilt axis Level arranged.
  • the reason here is the same as specified above for a swing arm with a pair of blow axes. This results in a balance of forces on the swing arm carrier, when the swing arm carrier with its hinged wings and hinged on them Blow boxes is in the desired position. If there are deviations, this will result Force imbalance automatically becomes one Return the system to a stable state.
  • blow boxes advantageously have a variable working width on. This takes into account the fact that changing especially in a slitter winder Roll widths must be processed. If you can change the working width, then you can Restrict airflow to the areas where a Role rests.
  • blow boxes closure means have for the outlet nozzles. These closures are not just limited to the working width change. One can with such closures also areas in the middle of the axial extension of the Shut down the blow boxes. This is especially true of Advantage if you wind several rolls at the same time, which are spaced from each other. Such Constellation arises, for example, in slitter reels.
  • the locking means self-regulating depending on a cover of the top formed by a roller are.
  • the outlet nozzles are only then released when there is a roll over it, and otherwise kept closed.
  • this can be done, for example, with check valves reach in the outlet nozzles where a Control pin suitable for opening the valves from the Surface protrudes.
  • a roll is wound the control pins are pushed in below the roller and open the valves. Valves off the roll remain closed.
  • there are other sensors conceivable, for example light barriers, pressure sensors or similar Common to all is that the closure means can only be controlled automatically where there is a role is to be supported.
  • closure means are formed by plates that are on the inside of the rest against the top wall. This gives one self-acting seal. The pressure inside the blow boxes presses the plates against the Wall and closes the outlet nozzles even more securely.
  • Fig. 1 shows a blow box 1, which, as later related 3 and 4 will be explained, is used in a roll winding device.
  • the Blow box 1 has a housing 2 with an upper side 3 and end faces 4.
  • the pivot pin 9 and thus the tilt axis 8 are arranged above the center of gravity of the blow box 1.
  • an air supply connection 11 provided by the air with a predetermined Pressure in the interior 12 of the blow box 1 can flow in.
  • the air can escape from the interior 12 escape through the outlet nozzles 6.
  • FIG. 3 and 4 now show the use of such Blow box 1 in a winding device 13, in a paper roll 14 is formed by a Paper web 15 is wound up.
  • the paper roll 14 lies on two support rollers 16, 17, of which at least one is driven.
  • a pneumatic is between the two support rollers 16, 17 Pressure relief device 18 arranged, the In the present exemplary embodiment, four blow boxes 1 having.
  • the blow boxes 1 are in pairs a swing arm 19 hung and articulated with the help the pivot pin 9.
  • the tilt axis 8 aligned parallel to the axis of the paper roll 14.
  • the Swing 19 are in turn articulated on a swing arm support 20 hung. This results in one second tilt axis 21, 22.
  • the second tilt axis 21, 22 runs parallel to the axis of the paper roll.
  • each rocker 19 is symmetrical to the second tilt axis 21, 22, i.e. the two blow boxes 1 of each rocker 19 are equally far from the second tilt axis 21 removed.
  • the Air supply connection 11 promoted air into the blow boxes 1. This air then passes through the outlet nozzles 6 out. Since both the blow boxes 1 articulated on their Swing arm 19 and the swing arm 19 are articulated on Swingarm carrier 20 are suspended and the swingarm carrier 20 symmetrically between the two support rollers 16 and 17 is arranged, then automatically results Setting in which the surfaces 3 of the blow boxes 1 an equal distance from the circumference of the paper roll 14, regardless of which one Diameter the paper roll 14 has. The distance can change overall with increasing roll diameter change. But it is 1 for everyone in all blow boxes Moment of wrapping approximately the same.
  • FIG. 2 From Fig. 2 it can be seen that for the two rows 6 plate-like flaps 23, 24 are provided by outlet nozzles are the ones with the solid lines shown position in which they the outlet nozzles 6th release into a position shown in dashed lines can be pivoted in the outlet nozzles 6 cover. You can now 6 for each outlet nozzle provide such a plate 23, 24. It is natural also possible, the plates 23, 24 each for groups provided by outlet nozzles 6. With this configuration it is possible for the air outlet from the outlet nozzles 6 on certain axial areas of the blow box 1 limit. You can then blow box 1 on the one hand, adapt to different roll widths. Man can also use the blow box when in the winding device 13 several axially next to each other, but at the same time spaced roles be wrapped. Out of a roll no air can be lost in the covered areas. This enables very energy-saving work. The air that has been pressurized becomes used almost exclusively for rolls of paper 14 supported on an air cushion.
