Definitions

  • the invention relates to a device for controlling a stack lift drive sheet-processing machine according to the preamble of claim 1.
  • the sheets to be printed are printed by the Taken from the top of a sheet stack, via a feed table to a feeder and fed from there to a first printing unit.
  • the printed sheets will be in the delivery on the top of a stack of sheets in the work cycle of the machine filed.
  • the stack support plates carrying the feeder or delivery stack are in the feeder or delivery arm by means of assigned stack lifting drives height-adjustable.
  • the stack support plate is moved in such a way that the top of the sheet stack remains in an intended height range. This is done analogously Lowering the stack support plate of the sheet stack in the delivery, also here corresponding to the signals of the stack height sensing, the motor of the stack lifting drive assigned control causes the lowering of the stack support plate.
  • the stack support plates in the feeder and delivery of sheetfed offset presses are not only with regard to the tracking movements to compensate for the sheet removal or the sheet tray, but especially for one automatic or a fully automatic batch change (non-stop operation) Can be moved over longer, especially programmed, distances. Furthermore, must when manually changing the stack in the feeder or delivery, the stack support plate to all the way down to the bottom of the pressroom to get a new one Retract sheet stack or the full stack in the delivery from the stack support plate refer to. These movements of the stack support plates are also executed after a command input by an operator.
  • the corresponding travel processes for the stack support plates are included on the one hand, to be carried out as quickly as possible (minimizing the time for a non-stop stack change), on the other hand, for reasons of personal protection or To avoid malfunctions in certain areas, a given maximum speed must not be exceeded. Also ensure that the stack support plate always move only in the physically possible area is to damage the linear actuator or the equipment in the Avoid feeders or cantilevers.
  • DE 4 207 305 A1 describes a device for controlling the stack carrier in Printing machines known in which the stack carrier with an electrical Position measuring device for constant detection of its position and for transmission of measurement data is connected to a programmable computer.
  • the displacement measuring device formed as a rotary potentiometer, which with the rotating element (Rotor) of the stack carrier suspension is connected.
  • Rotor rotating element
  • a connection be provided with the sprocket shaft of the stack lifting drive.
  • the coupling potentiometers take place with the interposition of a reduction gear.
  • DE-A 36 18 728 is a control device for the paper feed in one Copier known, in which the pulses of a coding device the height of movement of the stack support plate during each up and down movement is detectable.
  • the control device further comprises a counting device for counting the sheets that are subtracted one after the other.
  • From US-A-4,535,463 is a device for determining the on a stack support plate sheets of a stack known.
  • a control for a lifting system is known in which the lowest position of a stack support plate is detected by a reference sensor becomes. This reference position is in connection with the signals of an encoder evaluated.
  • GB-A-2 108 677 describes a device for position detection for the linear actuator a stack support device known.
  • the signals from an incremental encoder are used in conjunction with the analog signals of a corresponding Analog encoder evaluated.
  • the object of the present invention is therefore to provide a device according to the Develop the preamble of claim 1 in such a way that so while avoiding of the disadvantages mentioned above, the measurement device for the stacking stroke drive in a functional state for moving without time-consuming operating actions the stack support plate can be brought.
  • the signal of the position measuring device evaluating Control or an upstream evaluation unit in a present position the stack support plate with the drive motor switched off in the position of the stack support plate corresponding value can be entered, this reference value in connection with the current
  • the measured value for the further travel processes is saved and evaluated. So can in particular be provided as a reference value the distance of the upper edge of the stack support plate for example, the lower edge of a device of the boom or the boom housing to be recorded and via a switchable input device (laptop or Hand terminal) to the control / evaluation unit. It can be provided from this value, for example by means of a measuring stick or measuring tape, is still a predetermined value Deduct value.
  • This entered value is then used by the control / evaluation unit processed further in that this value in connection with the measured values acquired via the measured value device to form a reference point for the others Traversing operations is charged.
  • the advantage of the invention is in particular to be seen in the fact that, for example, after exchanging the chains or other interventions the stacking support plate cannot be brought into a predetermined position in the stacking hoist must, accordingly, the measuring system, which is designed in particular as an angle encoder to adjust and fix.
  • the measuring device as an angle encoder providing absolute angle values and this via a reduction gear with the shaft of the drive motor or the gear to connect the stack lifting drive corresponds to any position of the stack support plate exactly one digital angle value within the cantilever or the feeder.
  • This Angular value of the current position of the stack support plate then that of the hand terminal or measured value to be entered on the stack support plate, all are subsequent operations of the stack support plate can be carried out by the control, since a corresponding reference has been created.
  • the measured value there is provision for the measured value to create what has been explained above Cover for the operations of the stack support plate via a laptop to be connected or handheld terminal. Furthermore, provision can also be made for this measured value the control center of the printing press in a separate menu mode or via another Place existing input device in selectable units (e.g. mm or inch) along with the corresponding conversion.
  • the measurement specification for the measured value to be entered can be shown on a display.
  • Such a menu can also be used to set other parameters or settings for the Feeder or the boom as well as the corresponding operations of the stack support plate be enterable. This applies in particular to an extension of the travel options if Additional devices for in particular an automatic batch change (non-stop operation) can be installed later.
  • the chains 3 are in operative connection with a drivable Sprocket shaft 4, which is coupled to a motor 6 via a gear 5 is.
  • the motor 6 is also associated with an electrically triggerable brake, which in the figure is not shown, and in particular accomplished that when the Current or other emergency or danger situations, the stack support plate 1 in the respective position can be locked.

As already indicated above, these travel processes can be carried out manually Operating commands or programmed can be executed. Furthermore, the Control 7 not only perform position control for moving to predetermined positions, but also the speed that can be determined from a signal of the angle encoder 9 to control the travel process to maintain predetermined speed values.
