Definitions

  • the present invention relates to a sheet-fed printing machine with individually driven cylinders, wherein the individual drives used for improved collision avoidance between the individually driven cylinders have a galvanically separated double winding.
  • the invention is in the technical field of sheet-fed printing machines.
  • the classic drive type consists of a common engine that drives several cylinders, which are coupled together via a corresponding Zahnradzug to ensure uniform power transmission from the engine to the individual cylinders.
  • a high manufacturing cost is required to achieve a corresponding angular accuracy, which ensures that the individual cylinders are driven synchronously.
  • German patent DE 101 22 906 C1 therefore discloses a structure switching for speed control in case of failure.
  • this method it is provided to use the faulty drive as a guide value for shutting down the printing press.
  • the actual value of the faulty drive is thus used as a setpoint for shutting down the other individual drives.
  • the disadvantage here is that the faulty axis is switched off after error detection and a more accurate course of the spill is therefore not predictable.
  • a collision can also be caused by a jammed sheet.
  • torque-forming currents are possible in the case of short circuits in power electronics, which influence the motor in an uncontrolled manner. There is the danger that the intact drives can not follow the faulty drive, resulting in additional angular deviations and collision possibilities.
  • An inventive solution to this problem is a printing material processing machine with individually driven cylinders, wherein the electric motor of each individual drive consists of at least two subsystems and which is characterized in that the at least two subsystems consist of at least two galvanically separated, parallel double windings, at least one Current controller for both subsystems is present, both subsystems have their own control and weighted by a computer-aided monitoring and control logic are controlled.
  • the solution of the problem is thus achieved in that each individual drive for the corresponding cylinder consists of at least two subsystems.
  • the subsystems each have their own control and can thus be controlled separately from the computer-aided monitoring logic.
  • the weighting of the power distribution between the individual subsystems is carried out by the monitoring and control logic, wherein the at least one current regulator regulates the full power for all subsystems, the distribution or weighting but the monitoring and control logic takes over.
  • the at least one current regulator regulates the full power for all subsystems, the distribution or weighting but the monitoring and control logic takes over.
  • the individually driven cylinder is driven by at least two on the torque plane parallel and angle synchronous drives. If one drive or power electronics fails, the cylinder remains controllable. The monitoring of the drives takes place in each case on the torque level, so that an effect on the speed or the angular position of the cylinder is avoided.
  • a preferred development of the printing machine according to the invention is that it involves two subsystems that have a common current regulator or each have their own current regulator. It is preferred for the printing press according to the invention that two subsystems are used by means of two galvanically separated double windings. There is both the possibility that a common current controller corrects the two subsystems, as well as that each subsystem has its own, separate current regulator.
  • a further preferred development of the printing press according to the invention is that the two subsystems consist of two separate stator packs on one axis, while they have a common rotor.
  • An alternative embodiment of the single drive motor with two subsystems to the two galvanically isolated parallel double windings is the execution of the engine with two separate stator packs.
  • a further preferred development of the printing press according to the invention is that the two subsystems consist of two separate drives on one axis.
  • the advantage of using two separate and separate drives on one axis is that the two subsystems can operate almost completely independently of each other, as they have few common components. In this embodiment, therefore, the two subsystems have separate rotors.
  • a further preferred development of the printing press according to the invention is that a symmetrical distribution of the torque between the two subsystems is effected by the monitoring and control logic. By a symmetrical distribution of the torque between the two subsystems, a more accurate monitoring of the drive process can be realized.
  • a further preferred development of the printing press according to the invention is that the computer-aided monitoring and control logic ensures the current symmetry by comparing the current actual values.
  • the symmetrical distribution of the torque between the two subsystems is thereby ensured by the current controller converts a fixed to him fixed current setpoint to both subsystems.
  • the predetermined current setpoint may be e.g. be predetermined by the computer-aided monitoring logic.
  • the two current actual values which are present at both subsystems are compared in order to be able to intervene in the event of a fault, that is to say for deviating current actual values. This is done by an active device, e.g. from the computer-aided monitoring logic.
  • a further preferred development of the printing press according to the invention is that the computer-aided monitoring and control logic is set up in such a way that it additionally compares the current actual values with a reference value and switches off the subsystem which outputs a value deviating from the reference value.
  • the task of the computer-aided monitoring logic is not only to ensure the current balance, but also in case of failure, that is, if the two current actual values differ from each other or from a predetermined reference value, the defective subsystem, which provides a different current actual value accordingly off.
  • a further preferred development of the printing press according to the invention is that a phase correction is performed on the second subsystem by means of an offset for the position angle of the motor determined by a rotation angle actual value measuring device. Since the two subsystems are realized by means of different double windings, which can not be aligned absolutely exactly to each other, it is necessary the resulting deviations of the phase angle of the motor by an offset compensate. This offset is added digitally to the value of the measured value determined by the angle of rotation actual value measuring device.
  • a further solution according to the invention of the object is disclosed by a method for collision avoidance in a printing material processing machine according to one of claims 1 to 8, which is characterized in that the computer-aided monitoring logic monitors the two subsystems of the single drive and in case of failure of a partial drive the single drive over the own control with common current regulator of the still working partial drive switches off in an orderly manner.
  • the computer-aided monitoring logic monitors the two subsystems of the single drive and in case of failure of a partial drive the single drive over the own control with common current regulator of the still working partial drive switches off in an orderly manner.
  • the computer-aided monitoring logic shuts down the entire individual drive in an orderly manner by means of the separate control of the still functioning, at least one other partial drive.
  • the controls of the still functioning, at least one sub-drive and the faulty sub-drive must be coordinated with each other so that there is a collision-free shutdown of the individual drive of the corresponding cylinder.
  • Another solution to the problem posed is a method for collision avoidance in a printing material processing machine according to one of claims 1 to 9, which is characterized in that computer-aided monitoring and control logic monitors the subsystems of the individual drive and in the event of a fault partial drive the computer-aided monitoring - And control logic by means of the information about the disturbed part of drive performs a recalculation of the power distribution and thus over the other, still functioning at least one partial drive compensates for the error of the disturbed part drive.
  • the monitoring logic recalculates the current distribution and thus the distribution of torque between the subsystems, which then no longer with one symmetrical distribution of torque between the sub-drives of the still functioning, at least one partial drive compensates for the fault of the faulty partial drive and as a result the single drive can continue to be operated.
  • FIG. 1 the anti-collision system of the printing press according to the invention is described in its structural design.
  • an engine 12 of the individual drive drives the correspondingly assigned cylinder 13, wherein the angular position of the cylinder 13 is fed back to the system via a rotation-angle actual-value measuring device.
  • the electric motor 12 consists of a design with galvanically separated parallel double windings 9, 10. These are controlled separately by two separate inverters 7, 8 separated from each other.
  • the drive control is shown schematically.
  • the symmetrical distribution of the torque on the two subsystems 6, 19 of the individual drive is implemented by a common current regulator 2, which controls both the torque-forming portion of the current Iq, and the magnetizing current component Id.
  • a speed sensor 1 is a target speed value for the electric motor 12 of the cylinder to be driven 13 before.
  • the dependent current setpoint for both subsystems then becomes from a common current controller 2 symmetrically distributed to the two subsystems of the individual drive 6, 19.
  • Two ammeters 4, 5 measure the applied actual current values and report them back to the common current controller 2.
  • phase correction is present, which can act on one of the two subsystems 6, 19 in order to additionally effect a correction of the angular position of the cylinder 13 determined by the rotational angle actual value measuring device.
  • a computer-based monitoring logic 3 checks via the two two ammeters 4, 5 whether the current actual values of the two subsystems 6, 19 are distributed approximately equally in each case according to the symmetrical distribution to 50% each. If these deviate from the desired uniform distribution, or deviate from a respectively preset reference value, the monitoring logic 3 initiates an orderly shutdown of the subsystem of the individual drive, which generates the deviating value. If the faulty subsystem has been switched off, the entire drive system of all relevant individual drives of the printing press is slowly shut down without collision. In this case, the defective sub-drive is locked accordingly and the intact sub-drive is continued to operate adjusted to shutdown of the overall system.
  • the other intact subsystem is controlled by the monitoring logic 3 in such a way that the fault of the disturbed subsystem can be compensated thereby.
  • the monitoring logic 3 it is necessary that both information about the current distribution of the intact subsystem, as well as the faulty subsystem are queried and this information in the recalculation of the power distribution, which is necessary for compensation, are included. This is implemented by recalculating the current phasors, which are identical in both systems in the undisturbed system. In this operating mode, the entire system of all individual drives then continues to operate and the press is not shut down.
  • FIG. 2b an alternative embodiment of the separate drive when using two separate stator packs 16, 17 shown on an axis.
  • w1 and w2 which correspond to the stator packs but have a common axis and a common rotor 15.
  • FIG. 2 c shows a further alternative embodiment of the individual drive consisting of two subsystems 6, 19.
  • the stator is divided into two halves, but also the rotor 15.
  • This embodiment thus corresponds to the use of two separate drives on one axis. It has the advantage that standard components can be used.
