Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • the present invention has for its object to provide a device with which the separation of the paper web, largely independent of the paper quality, is trouble-free.
  • a first conveyor section 2 ends in a machine stand 1, with which a zigzag-folded paper web 3 (FIG. 3) is fed in a scale formation.
  • the paper web 3 runs over a deflection roller 4, where it is deflected and drops into a vertical stacking shaft 5 and is stacked therein to form a stack 6 (FIG. 3).
  • the deflection roller 4 is formed by a plurality of circular disks arranged side by side on a shaft 4 ', around which endless belts 2' forming the conveying path are guided.
  • the shaft 4 ' is driven by a motor M.
  • the stacking shaft 5 has guides 7, 7 'on opposite sides, which form vertical guide planes 8 and 9 in a side view according to FIG. 1.
  • the stack 6 forming in the stacking shaft 5 lies with its sides formed by the folds of the paper web against the guide planes 8, 9.
  • the distance between the guides 7, 7 ' is set according to the format to be processed. The same applies with respect to any side guides that form 2 vertical guide planes parallel to the conveying direction of the conveying path.
  • the stacking shaft 5 is delimited at the bottom by a vertically displaceable stacking table 10.
  • the stacking table 10 has a crossbar 12, the ends of which are fastened to threaded sleeves 13.
  • the threaded sleeves are screwed onto spindles 14 which can be driven by a motor M2.
  • the stacking table 10 can be displaced between an upper and a lower end position, as is indicated in FIG. 1 by dash-dotted lines. In the upper end position, however, the stacking table 10 is below the displacement path of a separating knife 15, whereas in the lower end position it is at the level of a removal path 16.
  • a center plate 24 is arranged on the arms 23 connected to the crosspiece 12, on which two side plates 25 are pivotably articulated (in the direction of the arrows shown).
  • the side plate 25 is pivoted by linear motors 26. In the upper end position of the side plates 25, together with the middle plate 24, they form a flat support surface 11 for the stack of forms 6 formed in the stacking shaft 5. If the side plates 25 are pivoted downwards, the stacking table 10 is formed a cambered support surface 11, the apex formed by the central plate 24 is oriented transversely to the conveyor path 2.
  • the linear motors 26 can be operated while the device is running and the top position can thus be leveled at any time.
  • the stacking table 10 is first brought up to below the path of movement of the cutting knife 15. In this position, the side plates 25 are pivoted upward and form a flat support surface 11. The stacking table 10 is moved downwards in accordance with the supply of the form sheets or the growth of the stack 6. At the same time, the side plates 25 are gradually pivoted downwards in order to compensate for the height difference which arises between the fold sides of the stack 6 and the center of the stack. The side plates 25 are pivoted downwards in such a way that the form sheets located at the height of the separating knife are always aligned horizontally.
  • the side plates 25 are folded up again for the transfer of the stack 6 to the removal path 16, as a result of which the support surface 11 is aligned coplanar with the latter.
  • the transfer takes place by means of an ejector 22 which can be moved across the stacking table 10 and back in the direction of the double arrow shown in FIG. 1.
  • a carriage 27 is mounted in the machine stand 1 by means of a linear motor (not shown), which can be moved back and forth parallel to the cutting knife 15.
  • This carriage 27 is provided with a vertical guide rod 28, at the foot end of which a piercing wedge 29 is fastened.
  • a second, shorter plunge wedge 30 (in the direction of the double arrow shown) can be moved up and down by means of a drive, not shown.
  • a motor-operated swivel shaft 31 is also mounted on the carriage 27, to which a spreading tongue 32 is fastened. This is in its rest position (indicated by dash-dotted lines in FIG. 4) in a recess on the underside of the piercing wedge 29.
  • the height of the expanding wedge 29 is selected with reference to the separating knife 15 such that it moves directly under the expanding wedge 29 during forward and return. As a result, the separating knife 15 moves between the expanding wedge 29 and the expanding tongue 32 when the latter is pivoted downward in the working position shown in FIG. 4 (with solid lines).
  • FIG. 5 shows the lower right edge of the stack 6, the side plate 25 being pivoted horizontally and the support surface 11 of the table 10 being aligned coplanar with the removal path 16.
  • the cutting knife 15 has a cutting edge 18 which is inclined to the guide planes 8, 9. At least on its upper side, the separating knife 15 is preferably provided with air outlet nozzles 17 which are connected via air channels to a blown air source, not shown.
  • a pneumatic cylinder-piston unit 19 moves the separating knife 15 from its rest position shown in solid lines to an end position shown in dash-dotted lines, in which the cutting edge 18 lies beyond the stacking shaft 5.
  • the cutting knife 15 moves through slot-shaped openings 20 and 21 in the guide levels 8 and 9, respectively.
  • the described device works as follows. At the start of the stack formation, the stacking table 10 is in the upper end position, the separating knife 15 being withdrawn into the rest position. The paper web 3 transported in scale formation falls over the deflecting roller 4 onto the stacking table 10 (the side plates 25 of which are swung up into the horizontal) and stacks between the guide levels 8 and 9. The stacking table 10 is now moved continuously downwards by rotating the spindles 14 , so that a stack 6 of the desired height is formed on the plates 10 between the guides 7 and 7 '. During the downward movement of the stacking table 10, its side plates 25 are also gradually pivoted downward, as a result of which the underside of the stack bulges concavely. The side plates 25 are pivoted down only to such an extent that the form sheets located at the top of the stack lie horizontally, that is to say parallel to the separating knife 15.
  • the carriage 27 is moved from the rest position into the working position and the insertion wedges 29, 30 are pushed between the form sheets at a distance from one another.
  • the upper piercing wedge 30 is moved against the lower (29) and the form sheets lying in between are clamped.
  • the spreading tongue 32 is pivoted downward and the form sheet below it is clamped against the stack 6.
  • the side plates 25 are preferably pivoted horizontally and thus against the tongue 32 (FIG. 5). Then the separating knife 15 is actuated, which pushes into the gap 33 formed in this way and cuts the fold between the adjacent form sheets on the opposite side of the stacking shaft 5.
  • the stacking table 10 is lowered to the coplanar alignment with the transport path 16 and the stack 6 formed is pushed onto it and transported away with the ejector 22.
  • the stacking table 10 is again up against the cutting knife 15 moves on which in the meantime the beginning of the next stack 6 was formed.
  • the separating knife 15 is moved back and the new stack started thereon is placed on the stacking table 10.
  • the air passing through the air outlet nozzles 17 forms an air cushion under the newly forming stack, so that the bottom sheet of the new stack does not shift during the return stroke of the separating knife 15.
  • the stacking table 10 is now continuously lowered again until the new stack has been completely formed, whereupon the separating knife 15 is actuated again and the described process is repeated.
  • the cutting knife 15 for reducing friction can have other means, such as surface finish or balls or rollers, on its upper side instead of the means for forming an air cushion.
