Definitions

  • suction lifters themselves are designed as jumping vacuums. All suction nozzles are set in such a way that they are at a short distance above the sheet stack. When working correctly, the top sheet is lifted from the stack due to the suction of the suction nozzles and pressed against the suction nozzles.
  • a vacuum is formed in the suction cups and in the entire suction pipe, which causes the detected sheet to lift off against the spring after exact sealing of all four suction cups, so that air can be blown under the raised sheet immediately thereafter.
  • the suction nozzles support the picking up of the top sheet of the stack by loosening blowers. After this When the top sheet is lifted, the suction cups transfer it to the suction cups, which convey the sheet in the direction of the first printing unit. With the correct setting, the four suction cups of the suction head are usually able to stopperlessly separate the top sheet from the stack in the speed range specified above. If one of the four suction cups is set inaccurately, stoppers can still occur because the vacuum in the suction pipe cannot develop.
  • the entire space to be acted upon with vacuum consisting of a suction pipe and four lifting suction devices, is so large that, especially when processing sheets that are sucking through, a sufficient negative pressure is built up, which then triggers the lifting suction device to jump up.
  • This time delay and the need to adjust and adjust all four suction cups exactly in relation to the uneven surface of the stack takes time and sometimes leads to pressure interruptions.
  • suction heads Another problem with the known suction heads is that the two internal suction nozzles are arranged relatively far apart. The suction of the air blown under the raised sheet therefore causes the trailing edge of the sheet to sag in this area, so that the sheet may not be passed flat to the suction device, which can cause the sheet to be deformed when the sheet is transported further by conveying means.
  • the object of the invention is to provide a suction head which processes and feeds all types of paper and cardboard trouble-free at high conveying speeds.
  • the suction nozzles of the suction lifters can be fitted so that they can be replaced so that the suction head can be quickly adapted to the respective optimal requirements. For example, easily separable papers can only be processed with two suction nozzles because the separation process is not difficult.
  • a continuous suction bar can also be provided on the double suction device of a lifting suction device.
  • Incorrect suction is particularly effectively avoided if suction nozzles and the suction bar are provided with wart suction cups, which in particular increase the suction safety of the two suction nozzles or the suction bar when paper is being sucked through.
  • the small, cup-shaped wart suction cups cause the vacuum chamber to be closed more quickly with less air.
  • the lifting suction device 1 shown in FIG. 1 has a cylindrical guide part 2 which is connected via a holder 3 to adjustable and adjustable parts of a suction head, not shown. Above the holder 3 there is a hose connection 4 for a hose, which leads to the vacuum generator. On the cylindrical surface of the guide part 2, the guide cylinder 5 slides the suction chamber 6.
  • the suction chamber 6 consists of the mentioned guide cylinder 5, the cross tube 7 and the two suction nozzles 8 and 9 attached to it. Suction nozzles 8 and 9 are covered with rubber rings 10 which are provided with wart suction devices 11. Suction chamber 6 and suction nozzles 8 and 9 together form the vertically movable double suction device 12.
  • a bore 13 is provided centrally as an air channel within the guide part 2, in which a shoulder 14 is incorporated, on which a spring 15 is supported, which rests with its lower end on the cross tube 7 and thus constantly presses the double suction device 12 into the lower working position .
  • the stroke length limits a resilient limit holder 16, which is inserted into an annular groove in the guide part 2. By pulling out this limit holder 16, the double suction device 12 can be removed from the guide part 2 of the lifting suction device 1 and can be exchanged for another normal suction nozzle part.
  • a shoulder 17 limits the stroke distance of the double suction device 12.
  • the double suction device 12 of the lifting suction device 1 is in its lower working position, the wart suction devices 4 of the suction nozzles 8 and 9 being just firmly closed by a suctioned-up bend 18.
  • a vacuum is now rapidly formed in the suction chamber 6, so that the double suction device 12 is sucked vertically upwards until the annular end face 19 of the guide cylinder 5 abuts the shoulder 17.
  • the sheet 18 has reached its upper position, in which it is different from those not shown Feeders can be taken over.
  • the vacuum chamber of the suction chamber 6 is ventilated, so that the vacuum breaks down and the sheet 18 is released by the wart suction devices 11.
  • the spring 15 then presses the double suction cup 12 back into the position shown in FIG. 1.
  • Figure 2 shows a lifting suction device 20 according to the invention, which differs from that in Figure 1 only in that the axis of symmetry 21 of the guide member 2 extends at a small acute angle to the vertical 22.
  • This outward inclined arrangement of the guide part 2 causes a slight movement from the suction head to the outside during the upward movement of the double suction device 12, so that when the sheet is lifted the middle part of the suction sheet 18 particularly exposed to the suction of the air is additionally tensioned.
  • this measure is not necessary because the closely spaced suction nozzles 8 and 9 of a double suction device 12 itself have a stabilizing effect on the sheet, and moreover the suction nozzle 9 is closer to the middle of the sheet than if the suction device 1 or 20 were only would be equipped with a normal suction nozzle.
  • the cross tube 7 of the suction chamber 6 can be designed on its underside such that it has a receptacle 23 for a rubber suction strip 24.
  • This suction bar 24 is also provided with wart suction cups 11.
  • the design of the suction chamber 6 is basically no different than in the case of two suction nozzles 8 and 9.
  • the advantage of the suction strip 24 is only that it can be applied somewhat more quickly than two rubber caps 10 of the suction nozzles 8 and 9.
  • several suction nipples suck in simultaneously (e.g. 10).
  • a suction head 25 is shown in dash-dotted lines, the control and drive means of which actuate the two suction cups 1 in accordance with the task.
  • the double suction cups 12 of the suction cups 1 are in their lowest position.
  • loose air is blown out of the nozzles 26 by two box loosening blowers 27 at the level of each suction nozzle 8 or 9, and as a result can be seen in FIG. 5 that the uppermost sheets 28 of the stack 29 are loosened.
  • the suction cups 1 and 2 are acted upon by suction air, the uppermost sheet 18 is sucked in by the suction nozzles 8 and 9 of the double suction cups 12. This position is shown in FIG.
  • the double suction devices 12 can be exchanged very quickly for single suction devices 33.
  • the box loosening blowers 27 are to be replaced by the tubular loosening blowers 34.
  • the vertically movable part of the suction cups 1 can also be designed as a triple suction cup, that is to say provided with three suction nozzles.
  • the suction cups can also be designed as drop suction cups, the double suction cups being brought down to the surface of the stack by negative pressure. It is particularly advantageous if the moving parts are made of plastic or light metal, because it is then possible to manufacture light and cheap double-stroke vacuums that react or start very quickly. Otherwise, all the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
