Definitions

  • the invention relates to a method and a device for pivoting a bidirectional pivoting frame of a paper changing device in accordance with the preamble of claim 1.
  • DE 22 59 734 C2 discloses a device for connecting a running paper web to the end of a supply roll.
  • the web is pressed against the supply roll by the outgoing roll by means of one of two pressure rolls, each of which is mounted near the ends of a bidirectional swivel frame.
  • the bidirectional swivel frame pivots about the axis of the first or the axis of the second pressure roller.
  • the bidirectional swivel frame is supported by means of pneumatically operable pin-shaped bolts arranged in the side frame, which engage in bores in the bidirectional swivel frame.
  • the invention has for its object to provide a two-directional swivel frame for a paper roll changer having two pressure rollers and two optionally releasable swivel axes and a corresponding method in which a safe either / or release of its swivel axes for pressing against a paper supply roll is possible in an optional swivel direction.
  • the invention for example: as a result of the method and an associated single-acting locking device for mechanically locking the two-way swivel frame carrying the two pressure rollers, it is always ensured during an operating state that the two-way swivel frame is mounted at one end in the side frame, so that machine damage is avoided and the Operational safety can be increased.
  • a bidirectional swivel frame 1 consists of two side parts 2 arranged opposite one another; 3. Two trusses 4; 6 connect both side parts 2; 3, in both ends 7; 8 pressure rollers 9; 11 are stored, as known from DE 42 18 825 A1.
  • the pressure rollers 9; 11 can be designed pivotable and with knife rollers 12; 13 may be combined (not shown in FIG. 3).
  • the bidirectional swing frame 1 is by means of two synchronously actuated working cylinders, for. B. pneumatic cylinder 14; 16 can be swiveled both clockwise and counterclockwise.
  • the pneumatic cylinder 14; 16 are each on a side frame 17; 18 of the machine is pivotally mounted and the piston rod ends of the pneumatic cylinders 14; 16 are each centered with the side parts 2; 3 connected. Furthermore, with each side part 2; 3 towards the side frame 17; 18 facing pivot pins 21; 22; 23; 24 connected.
  • the trusses 4; 6 can at their through the side parts 2; 3 protruding ends of such pivot pins 21 to 24.
  • the pivot pins 21 to 24 engage positively in the side frames 17; 18 guides available. These guides 26 to 29 are designed as extending in the vertical direction, downwards in the direction of paper supply rolls 31; 32 open and closed recesses are formed.
  • the guides 26 to 29 are pivot pin-wide and temporarily hold the pivot pins 21 to 24.
  • a locking device 33; 34 arranged on both side frames 17; 18. It consists of a frictionally mounted between the side frame fixed guide rollers 36; 37; 38; 39; 46; 47; 48; 49 in the horizontal direction on the guide rollers 36 to 39; 46 to 49 slide back and forth, against Pivoting secured locking brackets 41; 42.
  • the locking bracket 41; 42 are each by means of a on the side frame 17; 18 stored, horizontally arranged working cylinders, e.g. B. pneumatic cylinder 43; 44 horizontally displaceable.
  • the pivot pin 21; 22 or 23; 24 each lie in pairs on the locking supports 41; 42 and, as explained below, can each form an instantaneous pivot axis 56 or 57 in a working position. Both current pivot axes 56; 57 are also at a distance b.
  • the bidirectional swivel frame 1 is to be brought from its rest position (FIGS. 3 and 4) to the left, ie clockwise, into a working position (FIG. 1) in which a running paper web 58 runs from a right expired paper supply roll 32 with a left rotating paper web roll 31 the following work steps are carried out: retract the piston rod and thus shorten the stroke length of the pneumatic cylinder 43; 44 from its central position (FIGS. 3 and 4) into a left end position.
  • the bidirectional swivel frame 1 can be swiveled about its left swivel axis 56 by the pneumatic cylinders 14; 16 extend their piston rods (FIG. 1) and thus the second pressure roller 11 of the bidirectional swivel frame 1 connecting the paper webs of both paper rolls 31; 32 makes.
  • the locking bracket 42; 42 is pivotally arranged in such a way that the left pair of pivot pins 21; 23 or the right pair of pivot pins 22; 24 is completely released when the right pair of pivot pins 22; 24 or the left pair of pivot pins 21; 23 inevitably safe in his Leadership 27; 29 or 26; 28 on the locking bracket 41; 42 lies on.
  • the guides 26 to 29 may take the form of an inverted, i.e. H. Have U rotated by 180 °, both legs also being able to expand outwards.
  • the side frame 17; 18 can also consist of a scaffold which is arranged on indicated supports 61 (only shown in FIGS. 1, 2, 3).
  • the pneumatic cylinder 14; 16; 43; 44 can be designed as double-acting working cylinders, the connections and controls of which are not shown and whose actuation can take place from a machine control station, not shown.
  • each linear guides 68; 70 and 69; 71 attach, on or in which locking bolt 62; 64 or 63; 65 (shown in each case in FIGS. 1, 2 and 4 in section) by the force of springs 67 in each case then parallel to the longitudinal axes of the guides 26; 28 and 27; 29 are moved when the left pair of pivot pins 21; 23 or the right pair of pivot pins 22; 24, that is, the left pivot axis 56 or the right pivot axis 57, the guides 26; 28 and 27; 29 leaves.
