Definitions

  • the invention relates to a device for winding webs on winding sleeves provided with an adhesive application, which are supported on driven shafts or mandrels of at least two winding stations rotatably mounted about a central axis and provided with a rotary drive, with guide rollers leading the winding to be wound, with one Web cutting separating knife and with a device for pressing the new web start formed by the separating cut on the reel to be rewound.
  • a separating knife attached to a pivotable lever is provided, which cuts the web between the two winding stations by swiveling in accordingly, whereby on the pivoting lever carrying the separating knife a pressure roller is mounted which, during the pivoting-in of the cutting knife to make the cutting cut, presses the beginning of the path formed by it against the new winding sleeve provided with a glue application.
  • protruding flag which lies in an uncontrollable manner between the initial turns of the web to be wound onto the new winding tube and possibly forms bulges or folds in the turns due to overturning and creasing, which not only can lead to imbalance, but also bulges and unevenness in of the web to be wound up, which prevent smooth winding and can cause permanent deformations in the wound web, which can be disruptive in later processing.
  • a turret winder which enables the winding of a web start formed by a separating cut on a winding tube without glue application and without a protruding flag in that by a winding tube driving and partially looping tape and by additional guide devices, from which is formed by the separating knife itself, the beginning of the web is introduced into the gap formed between the run-up web and the web pressed against the winding tube by a pressure roller and the winding tube is clamped and carried in such a way that the beginning of the web wraps around the winding tube in a force-locking manner.
  • This known device is not only structurally very complex because of the necessary pressing and guiding devices, but it also fails when smooth webs are to be wound up, which do not enter into sufficient frictional engagement with the winding tube. Malfunctions can also occur in this known device if the loop formed at the start of the winding by the beginning of the web is not already pulled out during the first rotation, so that the beginning of the web engages the winding tube in a frictional manner.
  • the object of the invention is to provide a device of the type mentioned, the one on the glue point protruding flag formed by the beginning of the web is avoided and a smooth, warp and wrinkle-free winding of the beginning of the web onto the winding sleeve provided with an adhesive is guaranteed.
  • this object is achieved in a device of the generic type in that the separating knife can be moved on fixed guides between a retracted and an extended position and on its way to the extended position, in which it is close to the web running to the almost finished wound roll penetrates and cuts through the new winding tube to be wound, approximately tangentially touches or almost touches the winding tube rotating in the feed direction of the cutting knife, thereby taking along the beginning of the path formed by the separating cut and pressing it onto the winding tube.
  • the cutting knife thus also forms a device that smoothly brushes the beginning of the web formed by the separating cut onto the winding tube, which presses the beginning of the web against the winding tube without a protruding flag, thereby ensuring a smooth and wrinkle-free winding.
  • the cutting knife is expediently guided in straight-line guides.
  • the cutting knife or the like behind its cutting edge on its side facing the winding tube with bristles. is busy. These press the coated beginning of the web elastically against the circumference of the winding tube, distance tolerances being compensated for.
  • the feed speed of the cutting knife is preferably greater than the peripheral speed of the winding tube.
  • a counter-knife which can be swiveled in or retracted which, in the swiveled-in or retracted state, forms a gap with the winding tube to be rewound, which the separating knife can be retracted with a scissor-like cutting of the web.
  • the separating knife is expediently moved by a pneumatic piston-cylinder unit that extends and retracts it.
  • a device blocking the cutting knife in its retracted position is provided, which only releases it by a control device when the piston-cylinder unit or units with which the pneumatic knife moves the cutting knife into the extended position Pressure is applied so that the cutting knife moves out suddenly after the blocking has been released. Because of this abrupt extension, the severed web start is carried along due to the acceleration exerted on it by the cutting knife and spread onto the winding tube.
  • the blocking device can consist of one or more pressure medium-piston-cylinder units, the piston rods of which engage in corresponding recesses in guide rods or the like of the separating knife.
  • the cutting knife with its guides and drive devices is mounted displaceably in and out of further guides of the frame the area of the winding roll that is formed can be extended to the winding tube after the beginning of the web has been glued on. Since the finished wound roll is usually lifted out by a crane and takes some time, the new winding roll has already assumed a considerable diameter before being rotated into this winding position after inserting or clamping a new winding sleeve into the winding station of the winding roll that has just been lifted out can be. For this reason, it is necessary to move the cutting knife and possibly also the counter knife out of their ready positions in order to enable an undisturbed initial winding of the winding roll as long as it is still in its position during the gluing of the beginning of the web.
  • the counter knife which can be swiveled in is expediently mounted on further swivel arms and can be swiveled out of the region of the winding roll which is being formed.
  • two synchronously drivable support disks are offset by 180 degrees and are provided with two winding stations and each carry axially parallel guide rollers between these winding stations, which are offset radially outward relative to the winding shafts or aligned winding mandrels.
  • These guide rollers allow the web to pass close to the new winding tube on its way to the almost completely wound winding tube, so that the premature cutting knife only has to take the beginning of the web formed by the cutting cut with it over a short distance in order to spread it onto the winding tube.
  • At least one guide roller for the web is expediently mounted on the pivot levers carrying the counter knife which can be pivoted in, so that the course between the two guide rollers, between which the separating cut is carried out, can be precisely determined.
  • Two side parts 1 of the machine frame are connected to one another by a cross member 2.
  • two brackets 3 are welded at a distance from each other. They take up a continuous shaft 4, on which two levers 5 and 6 are also placed at a distance from one another.
  • These two levers 5 and 6 carry two guide rollers 7 and 8 and an angle lever 9 each.
  • Both angle levers 9 are connected to one another via a shaft 10, a bracket 11 with curved legs being fastened on the shaft 10 and carrying a knife 12.
  • Each of the levers 5 and 6 carries a bearing block 13, 14, in each of which a piston-cylinder unit 15 or 16 is pivotally mounted. The piston rods of these piston-cylinder units engage on the angle levers 9, so that the bracket 11 and thus the knife 12 can be pivoted. In the position shown, the knife 12 is in the pivoted-in position, that is to say in the separation position.
  • This knife 12 which is fixed in the separation position, is assigned a further knife 17 which is fastened to two rods 18 and 19. These rods can be moved axially back and forth via ball bushings in two guide cylinders 20 and 21.
  • pneumatic piston-cylinder units 24 and 25 are connected to the guide cylinders 20 and 21 via two plates 22 and 23.
  • the piston rods of this pneumatic piston Cylinder units are also connected to the knife 17. The latter is also in the position immediately before the cut in the position shown. In this position, the rods 18 and 19 are locked.
  • plates 27 and 28, which carry small piston-cylinder units 29 and 30, are welded to the guide cylinders 20 and 21.
  • This ironing process can be supported if the knife 17 is provided with bristles 32 on its upper side, for example.
  • the bracket 11 and thus the knife 12 are pivoted back via the piston-cylinder units 15 and 16 and at the same time the levers 5 and 6 are pivoted back via the piston-cylinder units 33, 34.
  • These piston-cylinder units 33, 34 are connected to the side walls 1 via spacers 35 and 36, the piston rods of these units 33, 34 engaging the continuous shaft 4 via levers 37, 38.
  • the knife 17 is moved back into the position shown in FIG. 2 by actuating the piston-cylinder units 24, 25.
  • the guide cylinders 20 and 21 slidably mounted on guides 41 and 42 on guides 41 and 42.
  • the guides 41 and 42 are parts of supports 43 and 44 to which rodless cylinders 47 and 48 are fastened via holders 45 and 46.
  • the pistons of these cylinder units have, in a known manner, radially projecting donuts which engage in plates 49 and 50, which are firmly connected to the guide cylinders 20 and 21.
