Definitions

  • the invention relates to a method for winding a web on at least one sleeve lying in a winding bed formed from two support rollers, wherein the resulting winding is pressed at least in the initial phase of the winding process by a pressure roller in the winding bed and after reaching an end target diameter at least is ejected at reduced winding speed with separation of the material web from the winding bed, and the resulting by the separation new material web start is then wound on at least one new introduced into the winding bed sleeve, wherein in the limited by the two support rollers and the current winding space the at least a new sleeve, at the earliest, as soon as the geometric conditions of this space and that of the sleeve allow that.
  • the invention relates to a device for carrying out the method.
  • the invention will be described below with reference to a roll winding device, in particular a roll cutting device, for paper and board webs. However, it is similarly applicable to methods and apparatuses on which rolls are wound and / or cut with other webs of comparable properties.
  • customer roll set is often used for the simultaneously wound single rolls. It follows from the aforementioned ratio of master roll diameter to customer roll diameter that one and the same master roll is "good” for several finished roll sets.
  • the slitter-winder one distinguishes between two basic types, the double-take-up roll winder and the back-up roll winder. In the former, to which the invention alone refers, are on two axially parallel support rollers as much sleeves in the axial direction next to each other in the winding bed as part webs are cut. So that the individual tracks can be wound onto the respective sleeves, the single-track starts on the sleeves must be determined.
  • the sleeves are regularly provided with a double-sided adhesive tape or the like.
  • the finished rolls want to give a certain winding structure.
  • the rollers should be regularly wrapped harder inside than in their peripheral area. In other words, the winding hardness should decrease from the inside out. Such a winding hardness curve can not be realized without suitable measures.
  • the single roles are practically only from the winding tubes. They are then so light that the forces resulting from their weight in the two nips between the rollers and the support rollers to produce the desired winding hardness are not sufficient. It is therefore known to press the single roll set with additional force into the winding bed at the beginning of the winding process by means of a load roller placed on its crest line; With increasing diameter and thus increasing weight of the individual roles, this additional force is of course deliberately reduced.
  • the procedure is as follows: If the current finished roll set has almost reached its nominal diameter, the working speed is reduced to 0 m / min over a predetermined ramp. Shortly before reaching standstill - when the standstill occurs, the actual diameter of the finished rolls naturally corresponds to the nominal diameter - the individual webs are cut off, the ends of which are still fixed on the respective rollers in the caster. Then, when the system is stationary, the finished customer roll set is ejected from the winding bed and a new set of tubes is introduced into the released winding bed - cf. eg DE 43 34 029 C2 , Only when this is done, a new winding process can begin.
  • the invention has the object of developing a method and a device of the aforementioned types so that the "loss times" described above are largely reduced without major construction effort.
  • This object is achieved according to the invention in the method of the type mentioned above by supporting the sleeve by means of a device which is in through the invariable gap between the support rollers in said space or moved out of said space and at its upper edge carries a machine-wide element, which is transformed in said space to a sleeve groove.
  • the object is achieved in that the device carries at its upper edge a machine-wide element that can be deformed in the said space to a sleeve groove.
  • a new set of winding tubes is already introduced at a time in the winding bed in the course of the set change, in which the current set of finished rolls is in full winding.
  • Prerequisite for the introduction of the sleeves is of course that of the two support rollers and the current winding limited space has become so large that he is able to accommodate the new sleeves. This condition is not given at the beginning of each winding process, but inevitably occurs as soon as the diameter of the currently wound rolls has reached a certain diameter.
  • slitter (1) comprises a roll (2) in which a full so-called mother roll (3) is rotatably mounted, deducted from the possibly. Up to 11,000 mm wide web (4) and then in a longitudinal cutting device (5) in single tracks is split. These individual webs are then fed into a winding bed (8) consisting of two support rollers (6, 7), in which they are wound on reel sleeves (12) into finished rolls (9). According to the figure, the single webs run through the gap (10) between the two support rollers (6, 7) on the sleeves; this run is referred to as "feed from below".
  • the individual webs initially wrap around one of the two support rollers (6 or 7), in order then to enter "from above” in the nip between the sleeves and the respective support roller.
  • the sleeves / single rolls set of two, in the marginal sleeve or individual roles / winding engaging, not shown here guide heads held.
  • a pressure roller (11) is provided, which presses the single roller set at least at the beginning of the winding process in the winding bed (8).
  • the slitter-winder (1) is finally equipped with a device (14), which serves the sleeve handling and the Fig. 3 and Fig. 4 is shown in more detail.
  • Fig. 2 illustrated situation shows the conditions that must prevail so that the slitter can already be fed in the ongoing winding process with a set of new cores.
  • Basis are dimensions, as they are known in practice. Thereafter, the insertion of sleeves (12) with an outer diameter of 120 mm for support rollers (6, 7) with a diameter of 1,000 and a center distance of 1,020 mm only possible when the diameter of the rolling rolls located in rolling (9) has a diameter 950 mm - the final diameter is assumed to be 1.440 mm.
  • Fig. 3 the device according to the invention is shown in its initial position.
  • the device (14) which is to form a sleeve groove (18) later, is arranged in the lower gusset between the support rollers (6, 7). It consists of a machine-width in the X-direction and narrow in the Y-direction (dimension preferably less than 40 mm) part, at its upper edge (15) mounted an element (16) which is also machine width in the X direction and in Y Direction also extends at most up to, for example, 40 mm.
  • the device (14) in a manner not shown vertically movable so that the element (16) through the invariable gap (10) between the two support rollers (6, 7) are pushed through in the upper gusset to there to be "spread out".
  • Said element (14) consists of a hinge pair (17) hingedly connected to the device (14) on a common longitudinal axis. These strips are here vertically close together, are not shown separately means but also from its vertical position in a horizontal swivel.
  • Fig. 4 Finally, the device in its working position in the upper gusset between the two support rollers (6, 7).
  • the strips (17) that are in Fig. 3 appear in the folded state, by spreading "spread” so that it now forms a support surface (18) which is able to support the sleeves.
  • the bar pair solution is only one variant among many other equally effective solutions; next to it, for example, telescopically extend to the left and right spreading parts or a hose-like device, which is spreadable after passing through the gap by means of a fluid.
  • FIG. 6 This one cut out Fig. 4 reproduced enlarged representation also serves only a better illustration, so that can be dispensed with a separate explanation.
