Definitions

  • the invention relates to a method for winding wound material supplied without interruption onto a plurality of winding cores, in particular on printing machines, with a double carrier roller having two support rollers, in the support of which the material to be wound is wound on a winding core into a roll and is thereby supported by a loading roller.
  • the invention also relates to a double carrier roller for winding wound material supplied without interruption on a plurality of winding cores, with two driven carrier rollers which form a support for each roll formed from the winding core and the material to be wound, and a load roller guided vertically above the support and with a feed device for the winding cores, a removal device for the rolls and a cutting device for cutting through the winding material.
  • the invention is used in particular at the end of printing presses which have to work in register and where it is still a matter of straight winding.
  • a method of the type mentioned at the beginning and a corresponding double carrier roller roller is known from US Pat. No. 2,989,262.
  • Two driven support rollers mounted adjacent to each other in the horizontal direction form a support for a winding core, which in turn is pressed in the vertical direction by a loading roller in the support.
  • the strip-like, continuously, ie without interruption, wound material is wound up one after the other onto winding cores, with the corresponding rolls ultimately being produced. It is a feed device for the winding cores on one side of the double carrier roller roller and on the other
  • a discharge device is provided for the finished rolls.
  • a knife-shaped cutting device is movably mounted in the gap between the two support rollers, with the aid of which the web of the winding material can be severed from bottom to top, in order in this way the end of the winding material on a roll and the beginning of the winding material on the next one Form winding core.
  • the arrangement of the cutting device in the gap between the two support rollers requires a certain amount of space, so that the support rollers themselves must be arranged with their axes further apart than would be necessary due to their diameter. This in turn means that the winding core must have a certain minimum size in its diameter, so that smaller winding cores cannot be used.
  • such a support roller roller provides good support for the roller on the support rollers.
  • the loading roller enables an almost constant web tension to be set even with small winding diameters, since the loading roller can be loaded and unloaded individually.
  • a support roller roller is also characterized in that the web of the winding material is wound up to the edges.
  • changing a completely wound roll and using a new winding core present certain difficulties.
  • such a double support roller roller can not only be used for simple tasks of sheet-like dyeing or coating of winding material, but also due to the very good web tension conditions also in printing machines.
  • EP-A-0 093 301 also shows a generic double support roller roller and a generic method in which the two support rollers are likewise arranged at a considerable distance from one another. This is necessary because the feed device for winding cores is passed upwards from below through the gap between the two support rollers in order to start the winding process on a new winding core. It is also possible to add a third support roller to the two support rollers to connect and allow the feed device for the winding cores to reach through the gap between the second and the third support roller. But here, too, there are limited geometric relationships, so that the winding cores must not be less than a minimum diameter. Likewise, the winding of the winding material at the beginning of the diameter of the roll that is being formed and the use of the loading roller present difficulties at this time.
  • a carrier roller with three carrier rollers is known. Two of the support rollers are pivotally mounted about a common axis. At the beginning of the winding on a winding core, this or the winding material wound up into the roll is supported on these first two support rollers. In order to ensure the support in the support formed by the first two support rollers, a loading device is provided. By pivoting the two first support rollers, a support is formed between the first and the third support roller for the roller, the diameter of which continuously increases, the second support roller being arranged below this support. During the pivoting movement of the first two support rollers about their common axis, the roller is picked up by a pivoting device.
  • the roller As soon as the roller has reached its final diameter, it is moved out of the carrier roller roller with the swivel device beyond the third roller. While the roll is only supported on the third support roller, the first two support rollers swivel back to their starting position and take up a new winding core in their support. At the same time, a cutting device which grips between the second and the third roll cuts the material to be wound, which is subsequently wound onto the new winding core. With this known roller roller constant web tension conditions can not be guaranteed. A loading device that presses the winding core or the roll into the support formed by the support rollers only comes when the first windings for use. In addition, it has a negative effect that the winding core is initially only guided through the support rollers and does not have its own bearing which prevents play in the winding direction.
  • Pope-Rollers which essentially consist of a stationary, driven support roller and a swivel device with receiving part for the bearings of the winding core.
  • the roll forming is not guided on two support rollers as in a double support roller, but based on the support roller during the winding process, with only a part of the weight of the roller generally being supported on the support roller.
  • the swivel device can be swiveled about a swivel axis mounted next to the axis of the support roller and serves to lift and remove a finished roll.
  • Such Pope-Roller are mainly used in the paper industry, specifically in the manufacture of paper and its further processing, e.g. B.
  • the invention is based on the object, starting from a double carrier roller of the type mentioned with carrier rollers arranged close to one another, to show a method and a double carrier roller with which it is possible to achieve largely constant web tension conditions, automatically, i. H. to work without interruption of the supplied winding material, to enable a problem-free change and to wind up with exact edges.
  • this is achieved in the method of the type described in the introduction in that the material to be wound is first wound onto a winding core resting on the two support rollers of the double support roller roller until the roller has sufficient weight for the pressure on a support roller which the stationary mounted, driven Is part of a rolling station with a swivel device for the winding core, that the role with the swivel device is taken over by the support of the double carrier roller and with the release of both carrier rollers via the second carrier roller onto the support roller of Rollstation relocated and there is finished winding until the intended final diameter of the roll.
  • the winding process begins on the support rollers of the double support roller roller and using the loading roller, so that from the beginning it is possible to wind a hard core, provided that no telescoping occurs during further winding.
  • constant web tension conditions should be created from the start.
  • the load roller also offers the option of individually adjusting the pressure on one or both sides - depending on the requirements. The surface pressure results from the two contact areas on both carrier rollers. Only when the roll has a corresponding weight is the pressure released via the loading roller and the roll is then transferred to the Pope-Roller or into the roll station and finished there up to the intended final diameter.
  • the weight of the roll is already so great that the support force on the support roller of the roll station is sufficient to be able to work with constant web tension conditions and a hard core in register and without register errors.
  • the special advantage is achieved that the double carrier roller in the side part of the winding process is free again, for a longer period of time, so that it is easily possible to prepare a new winding core, position it and then ready to wrap it during the flying reel change To have available.
  • the finished wound roll can be removed at the same time, then a winding core can be picked up and placed in an intermediate station on the double support roller reel and the roll wound on the support rollers can then be taken over and pivoted onto the support roller of the roll station.
  • the swiveling process of the swiveling device of the rolling station is therefore used in every movement phase and used for the various functions specified. A separate transport device and its control is therefore unnecessary.
  • the path of the winding material can be cut in the movement from top to bottom, so that the directions of movement of the lowering of a new winding core into the support on the two support rollers and the direction of movement of the knife-like cutting device match.
  • a very precise timing between the two movements is easily possible and there is the advantage that the support rollers of the double support roller roller can be arranged relatively close together, which in turn results in the advantage that winding cores with a relatively small diameter can be used, and even with large working widths.
  • the support roller of the roller station can also be moved very close to the second support roller of the double support roller roller, which gives the entire device a short construction and also the takeover process of the roller between the double carrier roller roller and the roller station only takes a short time and only small paths need to be bridged.
  • the double idler roller of the type described above is characterized according to the invention in that behind the two idler rollers a roll station with its own stationary and driven support roller and an associated swiveling device is provided, that the idler roller has a larger diameter than the idler rollers, and that the swivel device around the axis of the support roller is pivotally arranged.
  • the support rollers of the double support roller roller can advantageously have a comparatively small diameter, while on the other hand, regardless of this, the diameter of the support roller can advantageously be chosen to be large, in any case larger than the diameter of the support rollers. Nevertheless, the support rollers and the support rollers can be arranged directly adjacent to one another. This design also ensures that the size of the contact areas and the surface pressure in the contact areas are largely inexpensive, so that web tension surges do not occur. The device is therefore particularly suitable for use in printing presses which have to work in register.
  • the swivel device can have two swivel arms, on which receiving parts for the winding core are arranged displaceably; the swivel arms with the receiving parts can be swiveled on the one hand into the area above the support rollers and on the other hand beyond the winding position of the rolling station up to a depositing station for the fully wound rolls, so that the swiveling device can perform a variety of functions which previously required separate device parts for their realization.
  • the winding core can be guided in axially secured bearings in the area above the support rollers and / or in the area of the rolling station. This also contributes to a precise winding.
  • the swiveling device of the rolling station can also be designed as a feed device for the winding cores and as a removal device for the rolls. It goes without saying that the swivel device must therefore sweep over additional swivel angles and a corresponding device is required to control this movement. However, since the receiving parts on the swivel arms must be operable in the radial direction anyway, the additional effort is low.
  • An intermediate station for depositing winding cores ready for winding can be provided by the swiveling device, from which the winding cores get into the support formed by the two support rollers.
  • the swiveling device from which the winding cores get into the support formed by the two support rollers.
  • the proposed embodiment enables the roll change to be fully automated.
  • the double carrier roller roller has a conventional machine frame 1 with two column-like walls 2 on the right and left, which are connected to one another in a bridge-like manner or are supported on one another. For the sake of clarity, only one wall 2 is shown. Between the two walls 2, two support rollers 3 and 4 are mounted in a fixed position, which are driven in the direction of the arrows shown.

  • the winding core 7 has a winding rod 9 and a sleeve 10 in detail. The sleeve is in the usual way on the winding rod 9 releasably attached.
  • the loading roller 8 which can be moved vertically in the guide elements 5 according to arrow 15, rests on the top of the roller 13 from the start; For reasons of clarity, the loading roller 8 is shown here in its upper end position, that is to say raised from the circumference of the roller 13.
  • Booms 16 are connected to the bearing of the loading roller 8 and carry a knife-like cutting device 17 which extends across the width of the web of the winding material 11.
  • the machine frame 1 also carries an intermediate station 18 and a slideway 19.

  • the slideway 19 ends relative to the receiving claws 6 on the guide elements 5.
  • displaceable locking bolts 33 are provided, which serve to receive or release the unit comprising the winding core 7 and the loading roller 8 and are driven by hydraulic cylinders 34.
  • a double carrier roller roller with its essential elements is thus provided.
  • the double carrier roller roller is followed by a roller station 20 corresponding to a known Pope roller, which has a support roller 21 which, like the carrier rollers 3 and 4, is mounted on the machine frame 1 in a stationary but driven manner.
  • the support roller 21 has a much larger diameter than the support rollers 3 and 4.
  • the rollers 3, 4, 21 are arranged so that they are tangent to a common horizontal plane from below.
  • the bearings of these three rollers are so close together that only the gaps required for the rotary movement of the rollers are formed between the rollers. This makes it possible to use comparatively small sleeve diameters.
  • the support roller 21 is driven according to arrow 22.
  • the rolling station 20 also has, as an essential element, a pivoting device 23 which can be pivoted about an axis 24, which at the same time forms the axis of rotation of the support roller 21.

  • FIGS. 2 to 7 are highly schematic, so that the essential steps can be better recognized.
  • the web-like winding material 11 is fed continuously according to FIG. 2 and reaches the support rollers 3 and 4 via deflection rollers (not specified in more detail) and is wound here on the sleeve 10 of the winding core 7 to form the roll 13.
  • the diameter of the roller 13 may have increased, for example, up to half the final diameter.
  • the loading roller 8 presses the roller 13 against the two support rollers 3 and 4, which is particularly necessary at the start of the winding.
  • the swivel device 23 of the rolling station 20 functions here as a transport device for the winding core 7.
  • the swiveling device 23 was swiveled clockwise and the receiving parts 26 extended so that the new winding core 7 is deposited in the intermediate station 18.
  • the receiving parts 26 are then moved in radially on the swivel arms 25 and brought under the winding rod 9 of the roller 13 (FIG. 4), taking over the winding rod 9 or the roller 13 and conveying them over the carrying roller 4 while continuing the winding operation until the roller 13 is placed on the support roller 21.
  • the load roller 8 has been raised before taking over the roller 13. This can, for example, in its upper end position this is shown in FIG. 1.
  • the unit formed from the winding core 7 and the loading roller 8 is then placed on the locking bolt 33 which can be retracted by the hydraulic cylinder 34 without first having contact with the winding material 11 (FIG. 5).
