Definitions

  • the present invention relates to a method according to the preamble of claim 1.
  • a method of this type is known from DE-A 2 018 769 and US-A 3 866 905. Thereafter, paper towels or the like, folded in succession with an edge, are placed on a first conveying path by a depositing drum, held resiliently at the lateral edges and pushed forward regularly from behind until a package of a certain size has formed. This is then pushed away by a driver or ejector behind which a new package is formed. With this procedure, paper sheets with cross folds, i.e. with three folds, cannot be processed because of their very different thicknesses. The paper sheets would have to be held firmly on the side so that the pressure generated from the back could press them evenly flat.
  • CH-A 630 041 shows a basically the same procedure. Support elements are provided to remedy the deficiencies mentioned, which enables the processing of printed sheets with a number of pages of approximately 64 pages. Today's newspaper presses are, however, able to output even higher page numbers.
  • the present invention has for its object to provide a method of the type mentioned, which allows products of any thickness to be processed and packets of any size to be ejected without causing damage to the products.
  • the delivery 1 of a folding machine places printed sheets 2 folded one after the other on a conveyor belt 3, which transports them to the inlet 4 of a device 5, where the continuous stream is converted into packs 6 of different sizes.
  • Parallel to the conveyor belt 3 is a turning element in the form of a by-pass, to which the printed sheets 2 can optionally be fed from the conveyor belt 3 by means of a switch 8 and at the end again placed on the conveyor belt 3.
  • the printing sheets 2 are turned in the turning element 7 about the axis of the incoming printing sheets parallel to the conveying direction.
  • a cover sheet feeder 9 for cover sheets labeled with the postal route is preferably arranged between the turning element 7 and the inlet 4.
  • the inlet 4 consists of a drum 10, which is wrapped by an endless conveyor belt 11 which interacts with a further endless holding belt 12, which acts vertically downwards against a conveying plane 13 and places the incoming printed sheets 2 with the preceding edge perpendicularly on the conveying plane 13 .
  • the conveyor level 13 is formed by a fixed slide rail 14. Along this slide rail 14 form two endless chain pairs 15 and 16 equipped with flexible edge holders, a conveyor section 17. The facing strands of the chain pairs 15 and 16 are directed in the same direction and driven at the same speed and follow lateral guide rails 18 for the printed sheets 2.
  • the flexible edge holders each consist of two flat plates Brushes 19, 20, of which the preceding one (19) projects essentially at right angles from the pair of chains 15 and 16 carrying them, whereas the trailing one (20) with its free bristle ends (in the area of the straight strands) against the bristle ends of the preceding (19) is inclined.
  • the brushes 19, 20 In the deflection area, that is to say in the area of the deflection sprockets, the brushes 19, 20 forming an edge holder spread out like a pair of pliers and close in a plier movement during the transition into the straight run.
  • the conveyor belt 11 ends at the end of the deflection area of the chain pairs 15, 16, where the brushes 19, 20 assigned to one another are just spread apart and places the incoming printed sheets between the brush pairs of the edge holders.
  • the two trailing brushes 20 push the incoming printing sheet 2 on the slide rail 14 in the direction of the arrow shown and pivot as soon as they reach the straight strand against the preceding brush 19 and hold the edge of the printing sheet 2 thus captured resiliently. Due to the regular arrangement of the brushes 19 and 20 on the chain pairs 15 and 16, the distance between the edge holders is constant, so that the printed sheets 2 placed on the conveying plane 13 have a regular mutual spacing along the slide rail 14.
  • the resilient edge holders each consist of two flat brushes 19, 20 with soft, resilient bristles, of which the preceding brush 19 protrudes essentially at right angles from the pair of chains 15 and 16 carrying it, whereas the trailing 20 with their free bristle ends (in the area of the straight one Trums) is inclined towards the bristle ends of the previous one.
  • the speeds of the delivery 1, the conveyor belt 3, the inlet 4 and the chain pairs 15, 16 are coordinated with one another in such a way that with each machine cycle a printing sheet is placed between the brushes 19, 20 of the edge holder pairs following the same cycle.
  • the conveying section 5 transports the printed sheets 2 upright, at right angles to the conveying direction and at a mutual distance from two parallel strapping bands 21 of a strapping device 22 - and against their resistance - on a subsequent conveying plane 23.
  • the strapping device is a commercially available product from ENDRA, 5340 AB OSS, Holland, so that their description can be dispensed with.
  • Parallel to the pairs of conveyor chains 15, 16 are two stationary guide rods 24 on which a carriage 25 connected to an endless chain 26 is mounted so as to be longitudinally displaceable.
  • the chain 26 can be driven forwards and backwards by a drive unit 27.
  • the slide carries a cylinder-piston unit 28, which a pair of ejectors 29 reaching past on both sides of the slide rail 14 (shown in the left end position in FIG. 1 and in the right end position in FIG. 2) reaches past.
  • the chain 26 can be driven at a much greater speed than the conveyor chain pairs 15, 16.
  • the ejector pair 29 can be moved upwards in any position along the conveyor path 5 between two printed sheets held by the edge holders. If, for example in FIG. 1, the first three printed sheets 2 are to be combined to form a package, the carriage 25 is moved so far forward that the pair of ejectors 29 come to lie between the third and fourth sheets.
  • the welding heads 31 are then moved toward one another and the package 6 strapped around the retaining plates 30, whereupon after the retaining plates 30 have been withdrawn, they can be pushed manually or mechanically onto a subsequent conveyor belt.
  • the strapping of the retaining plates 30 prevents the package 6 from being strapped too tightly and the associated deformation of the outer paper sheets.
  • the displacement paths of the endless chains 15, 16 and the ejector pair 29 are scanned by incremental displacement sensors and fed to a positioning control, not shown, which controls the movement of the drive unit 27.
