It must also be ensured that the stack support plate is always only physically possible area is moved to damage the linear actuator or the Avoid facilities in the feeder or delivery.
- DE 3 631 456 C3 describes a device for controlling a stack lifting device is known in which the control device influencing the motor of the lifting device with a pulse generator connected to the motor and a the work cycle of the Printing machine detecting clock is in operative connection.
- the controller also detects still the signal of a so-called stack height scan.
- This well-known facility works together with a double sheet control and serves in particular the purpose of Tracking movement of the stack support plate in the feeder depending on the substrate thickness (Thickness of the sheets) between a continuous and a discontinuous operation switchable design. Since here a pulse generator trained as an incremental encoder Motor of the lifting device is provided coupled to the so-called detection Absolute position of the stack support plate requires additional measures by which A position determination can be determined in particular each time the machine is switched on.
- 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 displacement measuring device for constant recording of its vertical position via analog measurement data and evaluation this measurement data is connected in a programmable computer.
- a path measuring device which along with the path of the stack support plate arranged measuring strips cooperates.
- the object of the present invention is therefore a stack lifting drive according to the preamble of claim 1 to develop such, so that avoiding the previously enumerated Disadvantages of the prior art are the control options for the stack lifting drive can be expanded and in particular personal protection and functional safety serving measure can be carried out with the highest accuracy.
- the drive motor of the stack support plate via a Reduction gear is assigned an angle encoder delivering absolute angle values, such that the reduction gear the entire travel of the stack support plate within of the feeder or the boom on an area ⁇ 360 ° of the angle encoder.
- this means that the reduction of the reduction gear for Coupling of the angle encoder to the drive motor is selected such that the rotor of the angle encoder with a travel of the stack support plate between the bottom of the The feeder or the boom and the maximum achievable height is not a full turn executes, i.e. clearly assigned a digital angle value to each stack support plate position is.
- the reduction gear to connect the angle encoder to the stacking stroke drive directly on the shaft of the Drive motor is attached. It can also be provided that the reduction gear with appropriate selection of the reduction on the chain wheel shaft of the stacking stroke drive, through which the stack support plate is moved is coupled.
- the absolute angle values can be removed in digital form in connection with the reduction gear for coupling to the stacking stroke drive ensures that each time the machine is switched on already a digital angle value that corresponds to the position of the stacking support plate in the feeder or Boom corresponds, is present.
- the stack support plate is moved according to predetermined, especially programmed values.
- the stacking support plate can then be entered a manual control command, for example to lower it all the way to the floor are brought down, here via the control of the drive motor assigned digital value of the angle encoder in connection with a specified target value compared and the corresponding movement command for the stack support plate according to this target / actual value comparison is performed.
- a manual control command for example to lower it all the way to the floor are brought down, here via the control of the drive motor assigned digital value of the angle encoder in connection with a specified target value compared and the corresponding movement command for the stack support plate according to this target / actual value comparison is performed.
- target values can also be used to approach the stack support plate.
- an angle encoder supplying absolute angle values in connection with the upstream reduction gear for coupling the Angle encoder to the stacking stroke drive
- at least one track in particular the least significant bit
- the drive motor to move the stack support plate within the intended travel path between the floor and, for example provide different speed values for the upper edge of the feeder. That's the way it is possible, e.g. to lower the stack support plate from a given position first to specify a high lowering speed and after reaching a predetermined distance the target position to be approached to reduce this speed.
- the invention makes it possible to design a particularly cost-effective one Provide drive motor in the stack lifting device because of the achievable resolution an angle encoder in conjunction with the intended reduction gear both Travel position and the travel speed can be determined with high accuracy and corresponding control signals can be generated. Furthermore, the invention avoids one the disadvantage associated with the prior art in connection with the rotary potentiometer, after which when changing the reduction gear, the signal generator, the chains of the Stack lift drive or other gear elements of the signal transmitter again exactly on one predetermined position is to be adjusted. According to a development of the invention provided that after installing the encoder in any orientation with respect the reduction gear or frame can remain and through an input process of a dimension corresponding to the current position of the stack support plate is created for the control to move to all positions.
- the chains 3 are in operative connection with a drivable Sprocket shaft 4, this via a gear 5 with a drive motor 6 is coupled.
- An electrically releasable brake is also assigned to the drive motor 6, which is not shown in the figure, and in particular manages that at Switch off the power or other emergency or dangerous situations the stack support plate 1 can be locked in the respective position.
- the drive motor 6, in particular as a brushless DC motor with a corresponding electronic commutation is, for example, directly over the shaft and a reduction gear 8 with an absolute encoder 9 via an Number of lines connected in the manner of a parallel bus.
- the reduction of the reduction gear 8 for coupling the angle encoder 9 is such that the entire Travel of the stack support plate 1 in particular between the floor and a maximum reachable upper position within an investor or jib is not quite one Rotation of the rotor of the angle encoder 9 causes.
- a method of the stack support plate 1 between the floor indicated in the figure and a maximum attainable top Position means that the digital values of the angle encoder are always different and the position of the stack support plate 1 assume values that clearly represent.
- the embodiment is the angle encoder 9 directly via the reduction gear connected to the shaft of the drive motor 6.
- the reduction gear 8 also with the gear 5 of the sprocket shaft 4 or the sprocket shaft 4 may be attached. It is crucial according to the invention that the total travel of the stack support plate 1 less than one revolution of the angle encoder 9 causes or that the entire travel of the stack support plate 1 to an area ⁇ 360 ° of the rotor of the angle encoder 9.
- the angle encoder 9 is designed as an absolute angle encoder, i.e. this are on a number of lines providing binary signals or in the form of a serial Data flow immediately after switching on the devices its rotor position (encoder disc) corresponding digital signals can be removed.
