Definitions

  • the invention relates to a method and a device for the shingled feeding of sheet-shaped printing materials to a printing press with a conveyor table, preferably a suction belt table in a rotary printing press.
  • a sheet conveyor of this type is e.g. known from DE-PS 713 529 in which endless suction belts rotating in the direction of the sheet run are guided over fixed suction containers provided with suction slots.
  • a sheet conveying device with endless suction belts which are guided around the conveying table via narrow suction channels and feed the printed sheets to the printing press by means of negative pressure.
  • further blowing openings are provided in addition to the suction openings of the suction chambers in the table.
  • the blowing air is said to cause the individually sucked-in sheet to lift slightly and to float on an air cushion.
  • This solution tries to reduce the static friction between the sheet and the conveyor table. In the case of substrates that are transported under shingles, however, this leads to lifting off the conveyor belts, since here each sheet is only guided in the front area on the suction belts.
  • a conveyor table with perforated suction belts running around suction openings is known, which has openings parallel to the edges of each suction belt, which are connected to the environment separately from the suction space.
  • the object of the invention is to develop a solution which eliminates the disadvantages mentioned above.
  • compressed air is blown against the conveying direction at a defined angle onto the conveyor table or in the region of the alignment unit between the scale stream, preferably between the front, arcuate printing materials of the scale stream facing the printing unit.
  • This has the effect that the imbricated substrates are safely fed via the conveyor table to the printing unit and at the same time the adhesive forces in the stream of shingles are eliminated or noticeably reduced in a defined area.
  • the device according to the invention is arranged in the region of the alignment unit or in the region of the conveyor table facing the printing unit. This is because at the latest when the printing material is applied to the front / cover marks, the adhesive forces between the neighboring printing materials must have been eliminated.
  • the solution according to the invention achieves smooth sheet transport even at higher machine speeds. This eliminates the disadvantages, such as multiple sheets or missing sheets, waves or deformations on the substrate.
  • a conveyor table 1 in the form of a suction belt table is arranged between a printing unit 2 and a feeder 3. It has a suction chamber 5, on the underside of which an axial fan 6 is connected. Suction chamber 5 and axial fan 6 form a common storage space for building up the required negative pressure.
  • Perforated suction belts 7 are guided in a conveyor table surface 10. The suction belts 7 are guided on the underside of the conveyor table 1 via tensioning rollers 9 and on the end faces via driving or leading shafts 8.
  • the conveyor table 1 is continuously broken through in the area of the suction belts 7, so that a suction air flow is present over the entire length of the conveyor table.
  • An alignment unit 4 with front marks 11 is arranged between the conveyor table 1 and the printing unit 2.
  • the conveyor table 1 and the alignment unit 4 are shown from the top.
  • a contact plate 15 and several front marks 11 are shown as part of the alignment unit 4.
  • the suction belts 7 are embedded in guide grooves in the conveyor table surface 10 and have evenly distributed suction openings 14. Parallel to the edges of each suction belt 7, ventilation openings 23 are arranged on both sides in the conveyor table 1, which are connected to the environment separately from the suction chamber 5.
  • a plurality of blowing devices 13 are arranged in a row transversely to the conveying direction 12 of the scale flow.
  • the stream of shingles is represented here by the shingled arches 16 to 18.
  • Fig. 3 the stream of shingles, formed by the arches 16 to 18, on the conveyor table surface 10 or the alignment unit 4 is shown schematically.
  • the first sheet 16 lies against the front marks 11 and the rear end lies above the sheet front edge of the sheet 17 following in the conveying direction 12.
  • the rear end of the sheet 17 covers the sheet front edge of the subsequent sheet 18.
  • the blowing device 13 is integrated in the conveyor table surface 10 .
  • the blowing device 13 is shown.
  • the blowing device 13 is embedded in the conveyor table surface 10. It can also be sunk somewhat deeper, but must not protrude from the level of the conveyor table surface 10.
  • the blowing device 13 consists essentially of a base body 21 which is detachably connected to the conveyor table 1.
  • the base body 21 carries an air-permeable surface which is formed from a multiplicity of openings due to a microporous structure 20.
  • the microporous structure 20 is preferably made of a sintered metal.
  • an opening 19 which is inclined at an acute angle ⁇ to the conveying table surface 10 counter to the conveying direction 12.
  • the preferred angular range of the inclined opening 19 is between 20 ° and 40 °.
  • opening 19 is transverse to conveying direction 12 extending slot formed.
  • several slots or bores can be arranged next to one another in the structure 20 and can be inclined at an angle ⁇ .
  • the base body 21 is connected to a compressed air supply 22.
  • FIG. 5 is shown analogously to FIG. 2, but the blowing device 13 is arranged separately in the microporous structure 20 and in the opening 19, here as a slot. Structure 20 and associated opening 19 are inserted into the conveyor table surface 10 in multiple rows across the conveying direction 12 of the printing materials 16 to 18. All blowing devices 13 of this embodiment are coupled to a common compressed air supply 22 (for all structures 20 with associated openings 19).
  • the blowing devices 13 with the microporous structure 20 and openings 19 connected to the compressed air guide 22 can also be arranged in multiple rows transversely to the conveying direction 12 and can additionally be arranged displaceably in the conveying direction 12.
  • the blowing devices 13 running transversely to the conveying direction are preferably arranged in the region of the conveying table 1 facing the printing unit 2 or in the region of the aligning unit 4.
  • the mode of action is as follows:
  • the printing material to be processed is fed from the feeder 3 in shingled form as a shingled stream in the conveying direction 12 to the printing unit 2.
  • the lower, front part of the printing material is transported by the suction belts 7 in a manner known per se and transported over the conveyor table surface 10.
  • each printing material is aligned on its front and side edge after it has been released beforehand by the suction belts 7 and the conveyor table surface 10.
  • compressed air flows continuously from each blowing device 13 under the stream of flakes.
  • each sheet 16 to 18 is securely fixed on the suction belts 7, but at the same time between the conveying table surface 10 and the stream of shingles and in particular between the shingled sheets 16 to 18, the adhesive forces or static charges (in the case of film) by building up an air cushion be canceled or greatly reduced.
  • the static friction between shingled sheets 16 to 18 in the shingled stream or the movement friction when aligning each individual sheet 16 to 18 in the alignment unit 4 is reduced, so that the shingled sheets 16 to 18 are transported exactly and professionally into the printing unit 2.
