Definitions

  • the invention relates to a feeder for sheets in a sheet-processing machine, in particular a sheet-fed rotary printing press, which has the generic features according to the preamble of claim 1.
  • blowing nozzles for pre-loosening are arranged next to one another in an adjustable manner and are directed at the top sheet in the sheet stack at the rear edge of the sheet and are constantly supplied with blowing air from a central blowing air source.
  • the supply to other blowing nozzles, which are different in design from the former, can be regulated in the feeder working cycle in order to form a kind of air cushion made of carrier air for the upper sheet, which is lifted off by suction cups.
  • the adaptation to different sheet material, in particular to different paper qualities takes place by adjusting the height and the direction of action of the nozzles, the air flow and by appropriate selection of the nozzle shapes.
  • the object of the invention is to increase the operational reliability of the feeder regardless of the quality of the sheet material to be processed and to increase the printing speed with inexpensive means and less energy consumption.
  • the invention solves this problem by training features according to the characterizing part of patent claim 1.
  • air is expelled from the separate blast air source advantageously via the nozzles in this foot and others , adjacent air-jet nozzles, which can be directed obliquely to the side from the center of the bow in a known manner, or possibly only via one of these two blowing nozzles.
  • the supply of the air nozzles (in the foot and in air blowers) and loosening blowers with separate blowing air is advantageously carried out by a relatively small compressor via a control valve, which is designed as a rotary valve and is coupled to the drive of the suction head, in particular drive members of the foot.
  • a control valve which is designed as a rotary valve and is coupled to the drive of the suction head, in particular drive members of the foot.
  • This feature has a particular advantage because it makes synchronous operation of the rotary valve with the drive elements of the suction head, in particular the feeler foot, easier and the blowing times for the separate blowing air can be determined more precisely and possibly also be extremely short.
  • the separate supply of the blowing nozzles for the air and for the separation air can be controlled more individually, since this blowing air is independent of the conditions of the general blowing air supply.
  • this separate blown air supply for separating and blowing under the lifted sheet enables higher pressures, with possibly reduced blowing times.
  • the general blowing air generation
  • some of the trailing edge blowers provided on the trailing edge in the region of the upper sheets of the sheet stack are Can also be connected to the separate blown air supply, which increases the flexibility to adapt to special operating conditions due to the higher pressure available.
  • Figures 1 and 2 show a plan view of the uppermost sheet 1 in the sheet stack and on the suction head 2 shown as a block diagram.
  • the feeler foot 3 driven in the work cycle of the feeder.
  • the separating device for example consisting of one or more suction cups, for lifting the top sheet from the sheet stack is not shown in the drawing for the sake of a better overview. This separation device can be designed in a conventional manner.
  • loosening blowers 4 In the area of the trailing edge of the upper sheet 1 in the sheet stack, loosening blowers 4 (FIGS. 3 and 5) directed to the trailing edge of the sheet are arranged in a row next to one another on a transverse tube 5. On the tube 5, rear edge blowers 10 offset from the center are arranged so as to be height-adjustable as a loosening blower for separating the uppermost sheet.
  • further diagonal blowers 6 are provided in the area of the upper sheet.
  • the trailing edge blower 10 and the diagonal blower 6 are permanently supplied with blown air from a central air supply 8 or another blown air source in the circuit diagram according to FIG. 1 via feed lines 7.
  • For the blowing nozzles 9 in the feeler foot 3 For the blowing nozzles 9 in the feeler foot 3 (FIGS.
  • a separate blower air supply is provided by means of a compressor 12 which is considerably less powerful than the central unit provided that is effective and controllable independently of the central air supply 8 with an increased pressure. If necessary, however, the rear edge blower 10 can also be supplied with separate blowing air.
  • the blown air from the separate compressor 12 is fed and controlled through line 13 via a rotary valve 14, the rotary valve 14 being coupled to drive elements of the suction head, preferably to drive elements of the sensing foot 3, so that the rotary valve 14 is synchronized with the Feet movement around runs and enables precise control of the separate blowing air in the nozzles 9 and blowers 11.
  • nozzles in the trailing edge blowers 10 can be supplied with the separate blowing air from the compressor 12 or another source of separate blowing air, if this increases the operational reliability when separating and in particular when lifting the top sheet from Sheet stack is achievable.
