  • the invention relates to an air control and / or air control device for air consumers on sheet-processing machines, in particular sheet feeders, with an air pressure source, from the one Overpressure exhibiting air flow generated and in time with the sheet processing Machine an inlet of small cross-section of an ejector can be supplied and through the ejector to an outlet of large cross-section of the ejector, wherein between the inlet and outlet of the ejector radial connection opens into the ejector and the radial connection of the Ejector is connected to the air consumer and wherein the radial Connecting the ejector leads to a vacuum consumer and the Outlet of the ejector leading to the atmosphere outlet of the air flow forms.
  • the radial port of the ejector As at the radial port the ejector when it flows through air with a negative pressure is generated, there is a negative pressure of the nipple.
  • EP 0 872 437 A is an air control and / or air control device known in the compressed air from a compressed air source via a Pressure regulator, an electronically cyclically controlled valve and a Pressure manifold fed to several Venturi intake pipes in suction heads becomes. From the outlet of the Venturi suction tube leads at an angle to extend this outlet a passage to a suction cup of a Sucker and another straight continuing passage to the outside air.
  • an air control device in which from an outlet of a blower and / or vacuum generator a line leads to several suction and / or compressed air consumers, in the one Control and regulating device via valves the setpoint pressure to the blower and / or Saugluftmontem regulates.
  • a device with a suction cup which is connected to a vacuum system, wherein a pressure sensor detects the vacuum pressure in the leading to the suction cup line and according to the suction cup supplied vacuum is regulated.
  • the object of the invention is therefore an air control and / or air control device to create the type mentioned, the simple is expanded and a fast, to the respective operating conditions adapted reaction of the air consumer allows.
  • This object is achieved in that the fact that several Ejectors with increasing flow cross-sections in the flow direction are arranged one behind the other, their individual radial connections merged into a common radial port are.
  • the object is achieved in that between the air pressure source and the ejector an adjustable throttle element is arranged; by that of the throttle element flowing through Volume flow is adjustable depending on production data and that several ejectors with increasing in the flow direction Passage cross sections are arranged one behind the other, the individual radial connections merged to form a common radial port are.

  • the production data can be the machine speed of sheet processing Machine and / or the type and quality of the and / or the format to be processed bow.
  • the sheets to be processed by relatively high weight or greater air permeability so is at a sucker as an air consumer requires a higher suction power, to capture the sheet to be detected also safe.
  • To the safe Capture at the right time and not late to occur can leave the switchable valve over a normal operation leading opened or reduced the flow resistance of the throttle element so that the required suction at the optimum time fully built up.
  • shut-off valve If the shut-off valve is activated during one turn the drive of the sheet processing machine defined working cycle at higher engine speed to an earlier angular position the drive than at lower engine speed, it is opposite a normal operation leading to an opening of the check valve, so that a larger angular range of the drive and thus a longer time to Is available, during which the suction pressure can be built up. Thus, the full suction power is available at the optimum time.
  • each ejector can be customized controlled and clocked and possibly the control and the clock individually to be changed.
  • Is the switchable check valve a 2/2-way valve, in one position the ejector with the air pressure source and in its other position the ejector is connected to the atmosphere, so takes place in the one position of the 2/2-way valve, a positive or negative pressure the air consumer and in the other position an admission the air consumer with atmospheric pressure, which at Unterbuchmontem means an immediate reduction of the vacuum.
  • the switchable check valve may be a solenoid valve.
  • the air pressure source can be a compressed air pump or a compressed air reservoir be.
  • the embodiments illustrated in the figures have a as Compressed air pump 1 trained air pressure source, from which a positive pressure air flow via a in Figures 1 - 3 designed as a solenoid valve 2/2-way valve 2 and in Figure 4 designed as a solenoid valve Switching valve 2 'can be fed to a plurality of ejectors 3, wherein only one ejector (3) is shown in each case. It will the compressed air flow supplied to the inlet 4 of the ejector 3.
  • the terminal 7 leads to one or more than known Hoover 8 trained vacuum consumers.
  • the outlet 5 of the ejector 3 leads via a silencer 10 The atmosphere.
  • each branch 13 leads to a 2/2-way valve 2, the together with an ejector 3 and a lifting sucker 8 each have a structural unit forms. This is each Hubsauger 8 individually controlled.
  • the basic structure of the embodiment 1, the ejector 3 is through a bypass line 22 bypassed, in which a controllable quick exhaust valve 23 is arranged. Should the raised by the Hubsaugem 8 bow be released again from the Hubsaugem 8, so the switching valve 2 'closed and the quick exhaust valve 23 is opened, so that the detected by the Hubsaugem 8 bow can be solved immediately.
  • the intensity of the Hubsaugem 8 on the Bypass line 22 supplied overpressure by one in the flow direction behind the quick exhaust valve 23 arranged adjustable Throttle 24 can be adjusted.
  • a Filter 25 is arranged in the conduit 9.
  • the time and duration of Actuation of the ejector or 3 with compressed air depending on Production data e.g. detected by sensors or manually in one Control unit to be entered, determined.
