Definitions

  • the invention relates to a device for severing a web on a turret winder with a knife bar that can be advanced to the web and has a cutting knife and a pressure device that can be delivered to the empty winding tube
  • Turret winders generally have two winding tubes, one of which is arranged in a winding position. After the formation of a finished roll, the sleeve with the wound web is pivoted from its winding position into a removal position, while at the same time an empty sleeve is brought into the winding position. During the pivoting of the empty and the wound sleeve, the web remains connected to the wound sleeve. Only when the wound core in the removal position and the empty core are pivoted into the winding position, the web is cut with a cutting knife and the trailing web start is connected to the empty core, so that a new package can be wound on it.
  • a generic device is already known from US-A-2 942 796, in which the web is simultaneously cut with a knife and the leading end of the rewind the web is connected to the still empty sleeve brought into the winding position.
  • the empty sleeve is provided with an adhesive strip for connection to the leading end of the web.
  • the corresponding end of the web is pressed onto the winding tube by means of a plate arranged directly below the knife. This pressure plate is pivoted simultaneously with the cutting knife. The knife cuts through the web immediately next to the empty tube pivoted into the winding position.
  • Such a device works satisfactorily as long as sleeves with a uniform diameter are used. If, for example, sleeves with a larger diameter are used, the knives will hit the sleeve in their severing position. This known device is therefore not suitable for the use of sleeves with different diameters.
  • Both the cutter bar carrying the cutting knife and the pressure device are arranged in a frame which can be moved relative to the winding tube in such a way that their position with respect to the winding tubes can be adjusted at the same time by moving the frame.
  • the frame can simply consist of a crossbeam and side bearing plates.
  • the traverse can run over rollers in a guide rail fixed to the frame.
  • the frame can advantageously be moved over at least one piston-cylinder unit.
  • the cutter bar can be advanced via at least one piston-cylinder unit.
  • the part of the device relating to the cutter bar and the piston-cylinder unit or the guide parts of the cutter bar is rotatably mounted according to this embodiment by means of bolts in the bearing plates of the movable frame, levers being arranged in a rotationally fixed manner on the free end of the bolts, the free ends of which guide rollers wear.
  • these guide rollers are guided along inclined surfaces of guide parts fixed to the frame such that the cutter bar is pivoted about the bolt depending on the position of the movable frame.
  • links are rotatably connected to the bolts, on which tension springs act, which always press the guide rollers against the inclined surfaces.
  • the pressure device can advantageously consist of a roller guiding the web. In this case, this can be delivered via at least one piston-cylinder unit, the cylinder or cylinders being or are permanently mounted on the movable crossmember.
  • the pressure device can also be slidably mounted on rollers in the guide rail fixed to the frame.
  • the web does not lie against the still empty winding sleeve coated with adhesive while the finished wound winding tube and the still empty winding tube is pivoted, it can be guided over a deflection roller downstream of the roller serving as a pressing device
  • Guide rails 2 and 3 are attached to the inside of the two side frames 1 of a turret winder.
  • the right side of FIG. 1 shows the guide rail 2 closed, while the left side of FIG. 1 shows the guide rail in section.
  • Rollers 4 run in the guide rails and are connected to plates 6 via pins 5.
  • These plates 6 are welded on the end face to a crossmember 7, with 7 piston-cylinder units 8 acting on the crossmember, which in turn are firmly connected to the side walls 1 via windings 9.
  • the crossbeam 7 can be moved back and forth in the direction of arrow A via these piston-cylinder units 8.
  • bearing plates 10 are firmly welded to the cross member 7 and, as shown in FIG. 2, are fork-shaped in their front end.
  • bolts 11 are freely rotatably mounted, on the outwardly facing ends of which levers 12 are clamped.
  • the free ends of these levers each have a guide role 13, which run depending on the set cylinder stroke of the piston-cylinder units 8 more or less on the inclined surfaces 14 of guide parts 15.
  • the piston rods of the piston-cylinder units 8 are fully extended.
  • the guide rollers 13 have thus also reached the highest point of the inclined surfaces 14. This means that the bolts 11 have been pivoted clockwise with respect to FIG. 2.
  • Handlebars 16 are firmly connected to the bolts 11, on which tension springs 17 act, which always press the guide rollers 13 against the inclined surfaces 14.
  • the ends of the bolts 11 opposite the levers 12 are firmly connected via brackets 18 to ball bushings 19, the guided rods 20 of which carry the cutter bar 21 at one end.
  • piston-cylinder units 22 connected to the ball bushings 19, the cutter bar 21 and thus the cutter 23 can be moved from the position designated by B in FIG. 2 to the position designated by C in FIG. 2, whereby the web 24 then suddenly is severed.
  • the rollers 26 and 27 guiding the web 24 become so far towards the sleeve 25 at the same time as the knife 23 moves out of the position shown in FIG. 2 moves until the roller 27 presses the web 24 against the prepared sleeve 25.
  • the axes 28 and 29, on which the rollers 26 and 27 are freely rotatably mounted are non-rotatably fastened in holders 30.
  • Rollers 31, which run in the guide rails 2 are freely rotatably mounted on the free ends of the axes 28 and 29.
  • the holders 30 are connected to the crossbar 7 via piston-cylinder units 32, so that the holders 30 and accordingly also the rollers 26 and 27 can be adjusted relative to the crossbar 7 when the piston-cylinder units 32 are actuated.
  • the function of the exemplary embodiment described above is explained below.
  • the figures show the position of a winder in which a winder 33 has reached its desired diameter.
  • the turning disc 34 has been pivoted so far that the second winding point with the prepared sleeve 25 has been pivoted into the vicinity of the web 24, which is guided over a deflection roller 35 so that the web 24 does not yet touch the sleeve 25 prepared with glue strips.
  • the rollers 26 and 27 are in the position shown in the figures and the knife in its position B.
  • the piston-cylinder units 22 and 32 are actuated simultaneously, causing the knife to move from its position B to the position C shifts, cutting the web 24.
  • a winding tube of larger diameter namely the winding tube 25 '(shown with dash-dotted lines in Fig. 2) are used, are controlled by initiators, not shown, the piston-cylinder units 8 only extended so far that the Guide rollers 13 have just just run onto the guide surfaces 14.
  • This position of the guide rollers 13 is shown in FIG. 2 with dash-dotted lines and provided with the position number 36.
  • the bolts 11 are consequently the largest to be used Winding sleeve 25 'has no longer been rotated clockwise.
  • the position of the guide rollers 13, the position of which is designated by 36 includes the position of the knife holder 21 and the knife 23 connected to the position number 37.
  • the extended position of the knife bar 21 from the position shown by the position symbol 37 is indicated by Position symbol 38 denotes. From this it can be seen that the cut again takes place near the inserted sleeve 25 '.
  • the stroke of the piston-cylinder units 32 does not need to be adjusted because the piston-cylinder units are pneumatic piston-cylinder units, the piston rods of which extend until the roller 27 is against a winding tube it applies the winding tube 25 or the winding tube 25 '.
