Definitions

  • the invention relates to a winding machine for winding a running paper web. Reference is made to the preamble of claim 1.
  • the winding hardness plays a role for the subsequent processing.
  • the winding hardness should drop from a certain initial value to an end value.
  • the waste should be as even as possible from the first to the last layer. It should have a certain gradient, i.e. not too strong and not too weak.
  • the course of the winding hardness should under no circumstances have jump points, e.g. a sudden drop.
  • Air volume or air pressure can be controlled according to the growing weight of the reel. It is also possible to extend the chamber along its length - i.e. across the web width - to be sectioned into individual chambers and each of these individual chambers to be provided with a pressure connection. In this way, the deflection of the winding can also be compensated for.
  • rider rolls are used, which are arranged parallel to the supporting rolls. With these rider rolls are exerted on the roll by a contact pressure. The contact pressure is controlled, whereby it becomes large at the beginning and decreases with increasing roll weight.
  • the rider roller thus allows the line pressure and thus also the winding hardness to be influenced and controlled in the desired sense.
  • the line pressure in the final phase of the winding is also very large.
  • the winding tension increases, so that the web can tear or crepe folds.
  • US-PS 2 461 387 describes a winding machine which has two driven carrier rollers of different diameters; the carrier roller with the smaller diameter is provided with a coating with a higher coefficient of friction and driven at a higher speed than the other carrier roller. As a result, tensile stress is exerted on the outer layer of the web.
  • DE-OS 27 57 247 relates to a winding machine with support rollers of the same diameter.
  • the winding hardness is controlled by changing the distance between the carrier rollers.
  • DE-PS 678 585 describes a winding machine with two support rollers, the first of which has a hard jacket and the second has a soft jacket.
  • the axes of the two rollers are in the same horizontal plane.
  • DE 38 39 244 describes a winding machine with three support rollers.
  • the first support roller is stationary, while the two subsequent support rollers are movable and are wrapped in a support belt.
  • the winding hardness should be controlled over the roll diameter by means of the support belt and by changing the positions of the second and third support rollers.
  • the support band should cause the largest possible support surface in order to lower the surface load.
  • This winding machine is extremely complex. It also has a particularly serious disadvantage: as soon as the paper roll has grown so that it is mainly carried by the support band, the support band can swing violently, so that the paper roll starts to "dance" and can be catapulted out of bed .
  • EP 0 157 062 B1 describes a winding machine with two support rollers and a rider roller.
  • the outer surfaces of all these rollers are made from a variety of formed individual fluid chambers, which are arranged axially next to one another, and which form the entire lateral surface of the roller in question with the formation of a joint with their individual lateral surfaces.
  • the support behavior of such a roller is naturally non-uniform due to the large number of impacts across the web width.
  • the invention is based on EP 91914763. This document therefore shows and describes a winding machine according to the preamble of claim 1. According to claim 1 of this document, the blow box can be removed from its working position by pivoting or moving. The separating device can be moved into its own working position after removing the blow box.
  • a disadvantage of this embodiment consists in the following:
  • the blow box has a very considerable construction volume and a correspondingly high weight.
  • the process or pivoting of the blow box takes up a very considerable amount of space, which is often not available.
  • the invention has for its object to provide a winding machine according to the preamble of claim 1, in which the blow box is stationary, so that no complex movement mechanism with associated drive is required, and also a smaller space is sufficient for the entire machine.
  • the inventor has thus proposed a simple solution.
  • the blow box is and remains stationary, at least after the first assembly of the machine. Only a comparatively small part of the blow box is made movable or movable, namely those wall parts which carry the sealing element in question against the supporting roller in question.
  • the separating device is designed and arranged in such a way that it can be retracted in its working position between the second support roller (which is not wrapped in the web of material) and the relevant pivoted or moved away wall part with the associated sealing element in order to separate the web, namely each time when a web roll is completely wound.
  • blow box 6 between the two support rollers. This is only indicated schematically here.
  • sealing elements 7, 8, which provide a seal between the walls in question Blow box 6 and the respective support roller 1 or 2.
  • FIG. 2 shows, in an enlarged representation, the crucial parts of the object of FIG. 1. From this one can again see the two rollers 1, 2, the paper roll 3 indicated by dash-dotted lines, the paper web 4 brought in from the left, and the blow box 6.
  • a separating device 9 can be seen as a further important element. This has a cutting edge 9.1 at its left end.
  • the separating device 9 can be pivoted about a pivot center, which in the present case can be pivoted about the axis 2.1 of the roller 2.
  • the pivot center could also be slightly offset from axis 2.1.
  • the separating device 9 has an essentially circular arc shape.
  • the details of the blow box can be seen more precisely from FIG. 3.
  • the blow box 6 and the two seals 7, 8 can be seen there.
  • the seal 7 is carried by a component 6.1 and the seal 8 by a component 6.2.
  • the two components 6.1 and 6.2 are parts of the support box 6. They are both essentially U-shaped in this side view in order to increase the rigidity. However, this is not absolutely necessary.
  • the two components 6.1 and 6.2 are components of the blow box 6. They will be referred to below as "supporting parts".
  • Support part 6.1 is displaceable, namely against the support roller 2. Note the position of the support part 6.1 shown in dashed lines. Support part 6.2, however, is pivotally mounted on the main part of the support box 6 - see pivot axis 6.3. Support part 6.2 can be shown in dash-dotted lines Position swiveled and is thus inside the main part of the blow box 6th
  • a guide device 10 is provided for moving the support part 6.1.
  • This comprises a guide pin which is hairpin-shaped in cross section. This extends over the entire width of the two support rollers 1, 2. It also includes guide rollers which can run in the guide bush 10.1 and which engage the support part 6.1 via connecting levers (not shown here).
  • the lower leg of the guide bush 10.1 has a bent end 10.2. This serves to raise the support part 6.1 slightly in the end region of its stroke.
  • the support part 6.1 consists exclusively of the U-shaped structure.
  • the wall 6.4 located under this support part 6.1 is permanently stationary.
  • a seal 6.5 is provided between the U-shaped support part 6.1 and the wall 6.4 below.
  • the support member 6 includes not only the U-shaped structure, but also a console 6.6.
  • the console 6.6 is articulated via the pivot axis 6.3 to an underlying, fixed wall 6.7 of the supporting box 6.
  • Support part 6.2 is pivoted into its position shown in broken lines.
  • the separating device 9 is pivoted in the direction of the winding bed until it assumes the position shown in broken lines, in which it cuts the paper web.
  • the paper roll is rolled (simultaneously or subsequently) over the support roller 2 in the direction to the right and thus ejected from the winding bed.
  • the device has another, very advantageous device.
  • a wall 11 can be seen in FIG. 3. This connects the fixed wall 6.4 to the fixed wall 6.7 of the blow box. It also extends over the entire length of the blow box. In the present case, it is perforated through a large number of holes. In this case, the bores are distributed absolutely uniformly over the surface of the connecting wall 11.
  • the connecting wall 11 has to perform the following functions in the present case:
  • a third, very important function is as follows: In the case of carrier roll winding machines, the paper web is torn off from time to time. In this case, the paper web falls into the blow box; this waste paper must be removed as soon as possible.
  • the connecting wall 11 serves in this case collecting such paper waste. If the paper waste lies on the connecting wall 11, it can be removed much more easily through one of the two end faces of the blow box 6 than if it were lying on the bottom of the blow box 6. The removal of the paper waste could also be automated, for example by means of a scratch or a rotating conveyor belt.
  • said perforation of the connecting wall could be distributed according to a certain pattern. It would be conceivable that the size or the number of bores in the connecting wall decrease towards the end regions. This could be useful because the paper roll bends particularly strongly in the middle area.
  • a blind could also be assigned to the connecting wall 11, with which it is possible to arbitrarily change the throughput of the individual compressed air flows which pass through the bores of the connecting wall 11.
  • FIG. Another embodiment of the invention is shown in FIG.
  • the blow box 6 and the two seals 7, 8 can be seen.
  • the supporting part 6.1 can now be pivoted - see pivot axis 6.3.
  • Supporting part 6.2 is slidably attached to the support box, specifically in the vertical direction.
  • Support part 6.2 can be moved along the arrow. This has the advantage that when the carrier drum 2 reaches the dot-dash position - for example, it has to be pivoted away because the paper web breaks and the carrier drum is packed - the sealing element 8 is automatically moved downward with the carrier drum 2.
  • the blow box 6 according to FIG. 4 has stiffening ribs 14 which connect the fixed wall 6.4 to the fixed wall 6.7 of the blow box.
  • stiffening ribs 14 which connect the fixed wall 6.4 to the fixed wall 6.7 of the blow box.
  • sheets 15 are attached, with which the air supply line is fastened in the blow box.
  • a connecting wall 11 is also provided in the embodiment shown, which is perforated and serves to catch the paper residues when the paper web is torn off.
  • the connecting wall 11 is arranged inclined between the fixed walls 6.4 and 6.7 in such a way that the paper residues slide downwards in the blow box and collect in front of the opening 16 embedded in the fixed wall 6.4. The paper residues can then be easily removed after opening the flap 17 arranged in front of the opening 16.
