Definitions

  • the invention relates to a device for winding a material web, in particular a paper or cardboard web.
  • the starting point of the invention is the patent publication JP 4-153153A.
  • This document discloses a device for winding a material web with the features that are specified in the preamble of claim 1.
  • Air squeezing element is provided a roller 101 which is rotatably mounted in pivot levers is. Pressure cylinders engage on the swivel levers, so that the roller 101 with the Winding roll can be brought into contact.
  • the winding core of the winding roll is in contact with a secondary transport device 31, 12 on which the (the air squeezing element 101 bearing) pivot lever are stored.
  • the during the winding process with the Carrier drum 64 in contact with the winding roll 1 (FIG. 7A) together with the Air squeeze element 101 away from the carrier drum into a reel change position ( Figure 7B) proceed.
  • a similar winding device, the air squeezing element preferably as a brush is known from EP 0714373.
  • the air squeeze element also serves the purpose of ensuring proper winding is possible if (to prepare a reel change) the winding roll on one Distance from the carrier drum. This will cause an undesirable drawing in of Prevents air between the layers of paper.
  • the air squeeze element also keeps up the drum change, the severed end of the web on the winding roll while this is still rotated and braked.
  • the pressure device belonging to the air squeezing element is controllable in such a way that the air squeezing element with a defined contact pressure is in contact with the winding roll, even if - as long as the winding process has not yet been completed is - the diameter of the winding roll is still increasing.
  • winding devices An additional requirement on the winding devices is that it is possible must be, in exceptional cases, to remove a winding roll prematurely from the machine. in In such a case, relatively little paper may have been wound up by this point has been so that the winding roll diameter (or the layer thickness) only one Fraction of the usually achievable value. In this case, the air squeezing element the known winding devices because of the relatively small stroke of the Pressing device, not to be brought into contact with the winding roll.
  • the invention is therefore based on the object, the device described above to further develop a material web so that the air squeeze element can be brought into contact with the winding roll even if a Reel change done in a relatively short time after the start of the winding process should be, i.e. even if the winding roll to be removed is exceptional has a relatively small diameter.
  • the invention is preferably applicable to the known winding machine according to Patent application WO 98/52858. After that it is a Winding machine, the carrier drum of which can preferably be displaced in the horizontal direction, in order to be able to adjust the level of the line force in the winding gap sensitively.
  • FIG. 1 An exemplary embodiment of the invention is described below with reference to the drawing.
  • FIG. 1 shows a winding machine in a schematic side view, respectively in different operating states.
  • a paper web 9 to be wound runs from below onto a carrying drum 10, which also "Press drum” is called.
  • the paper web wraps around the upper area of the carrier drum and finally runs through a winding nip, which the support drum 10 with a Winding roll 11 forms.
  • the winding roll 11 is created during a winding process on a Winding core, preferably a drum-shaped drum 12.
  • the drum 12 is on its both ends supported on a rail 13, which is part of a machine frame 14 is.
  • each of the machine frames 14 can be moved along a horizontal guideway 16, for example with the aid of a Threaded spindle 17 or a similar drive.
  • the carrying drum 10 rests rotatably in bearings 19, which are only symbolically represented as a point and which are displaceable along a preferably horizontal guide 18.
  • This is a hydraulic displacement device, not shown, is provided, which the carrier drum with a desired adjustable line force to the winding roll 11 presses.
  • the guide can be so long that the above Moving the winding roll 11 on the rails 13 during the normal winding process is not required. In both cases, however, the following applies:
  • This primary transport device 23 essentially comprises two pivot levers, each of which is pivotally mounted in a fixed bearing 24 is.
  • An important feature of the winding machine according to the invention is an air squeeze element 25, carried by the secondary transport device 15.
  • the air squeeze element 1 is some time before the end of a winding process, ie shortly before Start of a reel change process, for example from below onto the winding roll 11 pressed.
  • the new drum 22 moved down by means of the primary transport device 23, preferably 3 in a position in which there is still a certain distance between the new drum 22 and the guide rails 13. This is the so-called winding start position.
  • the paper web 9 still runs to the winding roll 11, whereby the new one Slightly wraps around the drum 22 and the new drum 22 carries the drum 10 again pushed away from the stop 21. This can in the new winding gap (between the carrying drum 10 and the new drum 22) the line force acting there already be set precisely before the start of the new winding process.
  • the new winding process is triggered in a known manner in that a separating element (symbolically represented by an arrow 30) the running paper web 9 is cut transversely. This creates a new beginning of the web, which is placed on the new drum 22, so that a new winding role 11 a arises; see Fig. 4. Now the full winding roll 11 is braked, the Air squeeze element remains in contact with the winding roll 11 so that the end of the paper web is held on the winding roll.
  • a separating element symbolically represented by an arrow 30
  • the finished winding roll 11 is at the end of the reel change process in an end position even further away from the carrying drum. If the Winding roller 11 is braked to a standstill, the air squeeze element 25 is from the Winding roll removed as shown in Fig. 4; the winding roll can now (for example with With the help of a crane).
  • an air squeezing element 25 Shown as an air squeezing element 25 is a brush that extends transversely extends over the entire paper web 9.
  • a pneumatic hose 26 is provided, which also extends across the winding machine extends and carries the air squeeze element 25. If the pneumatic hose 26 is pressurized with compressed air, he presses the air squeezing element 25 against the Winding roll 11 (Fig. 1-3). When the pressure is released, the air squeezing element 25 is removed from the winding roll 11 (Fig. 4).
  • the air squeezing element rests on a cross member which is attached at both ends to a pivot lever, so that the air squeezing element (as in the prior art) is pivotable up and down.
  • the air squeeze element 25 can be designed differently; instead of a brush is the use a single or multi-part roller possible; different designs are also in accordance Patent application 19908496 applicable.
  • a lifting device (designated in the drawing as a whole with 27) is provided which the air squeeze element 25 and its pressing device 26 carries.
  • a cross member 28 which extends across the winding machine extends from one to the other secondary transport carriage 15.
  • Each secondary transport carriage 15 has a preferably vertical guide 29 along which the cross member 28 is movable together with the air squeeze element 25. To move the cross member 28 along the guide track 29 is only a symbol Drive 31 shown.
  • the lifting device 27 serves the purpose of the air squeezing element 25 and its pressing device 26 in one corresponding to the current layer thickness of the winding roll Distance from the winding roller axis of rotation; see for example Figures 5 and 6.
  • a reel change is prepared, although the winding roll 11b is one (compared to Figure 1) has a small layer thickness S1.
  • 5 is the pneumatic hose 26 still depressurized and the cross member 28 is still in a lower one Position.
  • the cross member 28 with the air squeezing element 25 ramped up according to the existing layer thickness S1; after that it will Air squeeze element 25 by applying pressure in the pneumatic hose 26 to the Winding roll 11b created.
  • the secondary transport device 15 can the winding roll 11b together with the applied air squeezing element 25 into the reel change position transport; see Figure 6.
