Definitions

  • the invention relates to a roll cutting device for a material web with a cutting station for Cutting the material web into partial webs and a winding station for winding the partial webs into partial web rolls, one winding unit for each partial web roll is provided and at least two winding units in arranged a common winding position group are.
  • the invention has for its object the structure of several partial web rolls with the least possible effort to control.
  • the positioning drive has a sensor that the diameter of the Partial web roll determined and the partial web roll dependent positioned so that the circumference of all partial web rolls in the contact zone with the pressure roller lies on a straight line.
  • the positioning drive therefore no longer positions the partial web roll in Dependent on pressure, but only dependent on the geometry of the partial web roll, i.e. dependent on on the diameter of the partial web roll.
  • Man can position the partial web rolls so that their circumference in the area where they are in contact with the pressure roller, always lies on a straight line. So that's it geometric arrangement set.
  • the pressure roller can then with the desired pressure on the partial web rolls are held so that the winding hardness and Winding tension can be kept at the desired values. This decouples the positioning of the Partial web rolls from printing.
  • the pressure roller is preferably in a carriage arranged perpendicular to the axis of the partial web rolls is movable. With increasing diameter of the partial web rolls the carriage can then be moved away so that the function of the pressure roller over the entire winding process can be preserved. Inside the sled the pressure roller can still be moved using a pressure control that sets the contact pressure.
  • the carriage is linear is movable in the radial direction of the partial web rolls. This changes with increasing diameter of the partial web rolls the contact geometry of the pressure roller to the Partial web rolls do not, which further simplifies control.
  • the slide advantageously has a drive which controlled depending on the diameter of the partial web rolls is. So the sled gets more and more Always move the diameter of the partial web rolls so that the pressure rollers the diameter increase can follow.
  • the control of the force respectively the pressure with which the pressure roller on the partial web rolls is from the linear movement of the Sled decoupled.
  • Each winding unit advantageously remains with the Winding essentially stationary. This will make the Movement control simplified.
  • the positioning drive only has to ensure that all partial web roles with their scope in the area where they are on the pinch roller lie on a straight line. Layered Movements such as those caused by an increase in diameter of the partial web rolls would be required, the positioning drive disregard.
  • Each winding unit preferably has a pair of Swivel arms with bearing mandrels for roll cores, the swivel arms from a winding position are pivotable into a storage position. You use the swivel arms are then used for two tasks. For wrapping the swivel arms are brought into their winding position. The positioning drive can be active there be set if necessary. The swivel arms but are also used at the same time, the to move finished partial web rolls out of the winding position and put it in a storage position where it from the roll cutter, more precisely, from the winding station, can be removed.
  • the swivel arms are preferably in the winding position essentially vertical. In the winding position the weight of the partial web rolls increases with increasing Diameter too. If the swivel arms are vertical, they can take up the weight without holding elements must also burden.
  • the swivel arms individually parallel to the axial direction of the partial web rolls are movable. This can be done by a simple Change the position of the swivel arms different Set the widths of the partial web rolls.
  • At least one bearing pin of each pair is advantageous formed and driven by swivel arms as a mandrel.
  • the partial web rolls are then driven by a center drive driven.
  • at least one of the bearing arbors has a drive power can be transferred to the roll core. This happens expediently by training as a mandrel.
  • the material web is advantageously fed into the winding position group from above. This makes feeding easier.
  • the partial web rolls can then be held or Swivel arms can be added in the direction of gravity are supported at the bottom.
  • the pressure roller can also in their sled on a foundation or machine frame be supported without her Movement in conflict with the material web being fed device.
  • a roll cutting device 1 has a web feed section 2 for a material web 3, which with the help a slitter 4 cut into several partial webs shall be.
  • the partial webs then become partial web rolls 5, 6 wound up in two winding position groups 7, 8 are arranged so that the partial web rolls 5, 6 of adjacent partial webs to each other are arranged.
  • the partial tracks are in a switch arrangement 9 alternately transported to the left and to the right (based on the representation in Fig. 1), for example with the help of blowpipes 10, 11, the individually controllable Have nozzles.
  • the partial webs 18, 19 are then over deflection rollers 12, 13, guide rollers 14, 15 and guide rollers 16, 17 to the Partial web rollers 5, 6 out.
  • a pressure roller 20, 21 is provided, which forms a nip with the partial web rolls 5, 6, into which the partial webs 18, 19 are introduced.
  • the partial web rolls 5, 6 are on swivel arms 22, 23 stored.
  • the swivel arms are schematic using a shown drive 24, for example as Piston-cylinder unit can be formed from one essentially vertical position, as in Fig. 1 is shown, pivotable about 90 °, so that a fully wound partial web roll 5, 6 on the Floor 25 can be stored.
  • the partial web roll 5, 6 then travels a path as shown by the dashed line shown double arrow 26 is indicated.
  • Each partial web roll has a winding tube 27, in which engages a mandrel 28, 29 on each holding arm 22, 23.
  • the mandrels 28, 29 can for example be pneumatically operated. They are through schematically shown drives 30, 31 driven so that the Partial web rolls 5, 6 over their winding tube 27, that is over the roller core. It's about in other words, a center drive.
  • Fig. 2 With solid lines indicate the position of the partial web rolls 5 shown in which it is placed on the floor 25 are. With dashed lines is the winding position the partial web rolls 5 shown.
  • the pressure rollers 20, 21 are each on slides 32, 33 arranged in the direction of the double arrows 34, 35 are radially displaceable to the partial web rolls 5, 6. For this purpose, they can be moved on a machine frame 36 supported. On the sled 32, 33 are also still the guide rollers 14, 15 and the deflection rollers 16, 17th arranged. The pressure rollers 20, 21 are therefore at Wind the partial web rolls 5, 6 from the dashed shown position in which they are practically at the Wrap sleeve 27 abut in the solid lines Move position shown. Here they will under the action of a positioning drive, not shown, which is arranged on the slide 32, 33 with a certain pressure on the circumference of the partial web rolls 5, 6 held.
  • the movement of the slides 32, 33 is controlled with the help of diameter sensors 37, 38, which are continuous determine the diameter of the partial web rolls.
  • diameter sensors 37, 38 are continuous determine the diameter of the partial web rolls.
  • the diameter sensors can be used, for example, as a rangefinder be trained the distance from their position determine the extent of the partial web rolls 5, 6.
  • the diameter sensors 37, 38 provide information for two tasks. Firstly, the control of the movement the carriage 32, 33 and thus also the movement 20, 21 made with the aid of the diameter information. The more the diameter increases, the further the carriage 32, 33 must be moved. For that be the diameter values of all partial web rolls 5, 5 ', 5' ' for example averaged. But it is also possible that Diameter of the largest or the smallest or also to use one of the middle web rolls.
  • each individual web roll 5, 5 ', 5'' (Fig. 2) is also required for another task.
  • Each winding unit 39, 39 ', 39'' is namely provided with a positioning drive which holds the circumference of the corresponding partial web roll 5, 5', 5 '' on the pressure roller 20. More precisely, each partial web roll 5, 5 ', 5''is positioned so that all partial web rolls lie on a straight line in the region of contact of the partial web rolls with the pressure roller 20. If the pressure roller 20 is now subjected to the corresponding pressure force, then it is in contact with all partial web rollers 5, 5 ' , 5''with the same force, since all partial web rollers have assumed the same position here.
  • the positioning drive can, for example, by the Drive 24 may be formed when the diameter the partial web roll 5, 5 ', 5' 'is larger or smaller than that of another part web roll 5, 5 ', 5' ' Swivel arm 22 closer to or closer to the pressure roller 20 swings away.
  • Different diameters of the partial web rolls 5, 5 ', 5 '' can result, for example, if the paper web does not have a constant thickness over its width and therefore partial webs with different thickness result, the partial web rolls with different Generate diameters.
  • the individual swivel arms in the direction of the double arrows 40 can be moved individually. This allows different Partial web widths and different Set distances so that different cutting patterns can be driven.
