Definitions

  • the invention relates to a device for air control of feeder blowing air and feeder suction air in sheet feeders of printing presses, each with a rotary valve consisting of a valve housing and valve body.
  • Known feeder air control devices (Japanese GBM-OS No. Sho 59-190732) are designed as sliders with a solenoid, in which the valve body can be moved. Corresponding air lines are connected to each other that feed the feeder blowing air.
  • This control device has no device for regulating residual air.
  • Another disadvantage is that the feeder suction air discharge line and the feeder blow air supply line cannot be operated separately from one another. When the printing machine is switched off and running down, incorrect air supply lines are caused, which result in an undefined, unwanted paper sheet feeding into the printing machine.
  • a feeder air control in which the suction and blown air supply line to the sheet feeder can be controlled simultaneously via a manually operated rotary valve. If the rotary valve is turned by means of an adjusting lever, blown air reaches the sheet feeder to pre-loosen the sheet stack. Suction air is discharged from the suction heads.
  • the blown air is discharged into the environment by turning the actuator, the vacuum pump is now connected to a suction roller on the suction side.
  • the disadvantage is that no separate feed blowing and feed air control can be carried out. Another disadvantage is that the known device does not allow remote control. Finally, the known device has no device for discharging feeder misfire air.
  • German utility model 84 37 975 shows a pneumatic sheet feeder control according to the preamble of claim 1, in which feeder blowing air and feeder suction air are remotely controlled via two separate rotary valves.
  • the rotary valves are controlled via an electronic pushbutton switch, which determines whether an arc is present or not.
  • Feeder blowing air and feeder suction air are connected to a blower housing and thus constitute a closed circuit.
  • a disadvantage of this embodiment is that the valves arranged in the closed circuit cannot be operated separately from one another.
  • the problem underlying the invention arises to provide improved operating options, to provide improved control of sheet feeding into the printing press and to prevent unwanted paper sheets from being drawn in.
  • the object is achieved in that from the operator console and the sheet delivery, the control device for feeder blowing air and the control device for feeder suction air can be actuated separately by means of actuating means, the control devices having adjustable valve bodies and valve housings with additional openings for residual air regulation.
  • remote control could be used to create a separate operating option for both feeder blowing and feeder suction air from the sheet delivery.
  • a further advantage of the invention is the residual air regulation. Additional openings in the valve bodies prevent new sheets from being drawn into the outgoing printing press after being switched off. Additional paper can be saved by reducing the amount of paper waste, since there is no undefined drawing of new sheets into the press.
  • Another advantage is that the residual air regulation when switching off the printing machine prevents the feeding of new sheets with certainty and therefore no visual control of the application is necessary. This enables machine operation from anywhere.
  • valve bodies are supported in roller bearings. This reduces the bearing friction and creates a smooth operation.
  • the high surface quality reduces the friction in the valve reached.
  • the small air gap between the adjustable parts makes it almost impossible for air to escape.
  • the high surface quality also largely eliminates the risk of corrosion due to condensation forming in the air lines.
  • electromagnets are used to control the valve body. These electromagnets are non-positively connected to the valve body to be actuated.
  • pneumatic cylinders are used to actuate the valve bodies in the valve housings.
  • a printing machine with sheet delivery 1 and sheet feeder 2 is shown.
  • machine operation is also possible via a control panel 4 on the sheet delivery 1.
  • valve body 7 is adjustably accommodated in the valve housing 8 and in the valve housing 9.
  • the main air opening 12 and the residual air opening 14, which is arranged at an angle to the main air opening 12, can be seen in the valve body 7.
  • An adjusting screw 10 serves to regulate the blown air for pre-loosening the sheets of the sheet stack 22 (FIG. 1).
  • the blown air supply line 11 is connected to the blown air line 13, while the suction air line 17 is connected to the transport or lifting suction devices.
  • the blown air supply line 11 is connected to the blown air discharge line 13 via the main air opening 12 on the blown air side.
  • the valve body 7 is rotated, so that blown air can continue to flow to the feeder via the residual air opening 14 and the bypass 15 located in the valve housing 9, which to loosen the Serves sheet stack.
  • the dosage of the loosening air for the sheet feeder 2 is adjustable via the adjusting screw 10.
  • a travel limiter 21 serves as a stop for a rotating cam 20 which is connected to the electromagnet 18.
  • suction air supply line 16 and suction air discharge line 17 are also connected to one another via the valve body 7. If the feeder suction air is switched off via the operator console 3 or the control panel 4 at the sheet delivery, the valve body 7 is adjusted via an electromagnet 18 so that the suction air discharge line 16, 17 is interrupted and a pressure equalization with the atmosphere via the openings 12, 14 and 19 can take place. The sheet that is picked up then falls off the transport or lifting suction devices.
