Definitions

  • the invention relates to a device for controlling two or more straight benders in the all-round winner of a bow processing company Printing press, each arc straight pusher has a separate pneumatic drive which for Generation of alignment movements of the straight bend in the The cycle of the sheet sequence can be pressurized periodically with compressed air is.
  • a rotary valve In a device known from DE 196 16 422 C1 of the specified type is used to control the compressed air supply a rotary valve is provided, the input side with a Compressor and on the output side with the pneumatic drives of the straight benders provided as side stops is connected and the pneumatic drives periodically supplied with compressed air.
  • the housing of the rotary valve is connected to an actuator and can with the help of Actuator in its angular position in relation to the rotary valve be adjusted. This makes it possible to Setting the time at which the side stops act to change the sheet to be placed on the stack and to adapt to sheet braking, format, gripper opening. Measures to synchronize the movement of the side stops are not specified here.
  • the invention has for its object a device to control two or more straight straight bumpers at the beginning to create the type mentioned, with the one exactly in the same direction synchronous movement of the straight bumpers, for example a synchronous approach to the sheet stack and distance can be reached from this. Furthermore, the synchronous movements of the straight bumpers in their temporal Sequence to different parameters, such as machine speed, Format, substrate, print subject adapted can be.
  • each pneumatic actuator has a control valve for control the compressed air supply and that means are provided are through which the control valves each at the same time are operable in the same direction.
  • control of the individual in the same direction pneumatic drives of the straight pushers becomes an exact Synchronization of the advancement of the straight bend on reached the paper stack and thus a good stack formation and damage to the sheets during storage and alignment avoided to the stack.
  • the time of actuation the control valves can according to the invention in relation to the Machine time (machine angle) can be set to one Adaptation of the movement of the straight bend to the placement behavior to be able to adjust the bow, as it of the Machine speed, format, substrate and is dependent on the print subject.
  • the control device according to the invention has the further advantage that it is very inexpensive can be realized and that it is mechanical Design of the printing press largely independent is. Also the subsequent installation in existing printing presses is possible without great expense.
  • the actuation of the control valves can be different Way, for example mechanically, pneumatically, electrically or electropneumatically.
  • Means for electrical or electropneumatic Actuation of the control valves because the control valves are then with little technical effort in the immediate vicinity of the pneumatic drives, which in turn desirable for an exact synchronization of the movements is.
  • This is one way to To design control valves as solenoid valves. Should one Actuation of the control valves with comparatively less electrical power should be possible, so it is recommended to use a pneumatically pilot operated control valve with electromagnetic Pilot valve to use.
  • the compressed air for the Pilot control can either be the compressed air supply for the pneumatic drives or a separate compressed air source be removed.
  • the respective control command from a real-time computer are calculated and output, the real-time computer fall back on characteristics stored in a memory can influence the filing behavior of the sheets Parameters included.
  • the real-time computer is preferably and the characteristic curve memory is integrated in the machine control center.
  • control valves in the work cycle of the printing press can consist in that with the help of a electrical rotary encoder, for example a cam on the single-turn shaft and a sensor that interrogates the cam, at a certain machine angle an electrical one Control pulse for actuating the control valves or the pilot valves is produced.
  • a electrical rotary encoder for example a cam on the single-turn shaft and a sensor that interrogates the cam, at a certain machine angle an electrical one Control pulse for actuating the control valves or the pilot valves is produced.
  • the straight arc pusher 1 shown in FIG. 1 is on the side edge a boom stack 2 arranged. It consists of one in a swivel 3 to one to the side edge of the Boom stack 2 parallel axis pivoted Stop plate 4, which is 5 can be periodically moved back and forth in the swivel angle S.
  • the pneumatic drive 5 via a line 6 to the output of a control valve 7 connected, the input via a line 8 to one Compressed air generator 9 is connected.
  • the control valve 7 is pneumatically operated with the help of an electromagnetically operated Pilot valve 10 in its two switching positions switched.
  • the control air required for this is supplied with a Branch line 11 taken from line 8.
  • the electromagnet of the pilot valve 10 is to a real-time computer 12 connected to a defined one in time with the arc Point in time or at several defined points in time the electromagnet of the pilot valve 10 per cycle energized briefly with a switching voltage, causing this the pilot valve 10 is actuated and thereby switching of the control valve 7 and loading the drive 5 with Compressed air causes.
  • the real-time computer 12 has one Characteristic curve memory 13 connected to the machine speed and others influencing the placement behavior of the sheets Contains characteristic curves taking into account which the one that applies to the real-time computer Calculation of the time to activate the pilot valve 10 is abandoned. For example, with a the appropriate point in time given the particular machine speed for pressurizing the drive 5 for the printing material Cardboard at 210 ° and thin paper for the substrate 270 ° of the machine angle. The duration of the measure Excitation of the electromagnet of the pilot valve 10 is so dimensioned so that the action of the Drive 5 with compressed air is sufficient to the straight bend from the end position parked by the boom stack the entire swivel angle S completely into the alignment position to move.
  • Figure 3 shows a modification of the control device according to Figure 2, which consists of the control air for actuation of the control valve 7 from a separate compressed air generator 14 supplied to the pilot valve 10 via a line 15 becomes.
  • control device also for controlling a pneumatically driven straight arch pusher on the front edge of a boom stack can be used.
  • This can it may be desirable for the sheet straight pusher to be at the leading edge of the stack not in sync, but time-shifted to curved straight pushers arranged on the stack side edges is moved. To achieve this, for example, with Using a delay element from the real-time computer emitted electrical control pulse for the pilot valve of the front straight arch pusher are delayed.
