Definitions

  • the invention relates to a method and a device for controlling the drive motor of a stack lifting device on a sheet-fed printing press.
  • a method and device is e.g. known from FR-A-1 317 119.
  • the drive device of a stack lifting device should basically accelerate and brake gently so that the individual sheets of paper in the stack do not slip. Nevertheless, the braking distances should be as short as possible. It is also necessary to move the stack quickly in order to achieve a high operating speed of the printing press.
  • the object of the present invention is to meet the above-mentioned requirements by designing the device for controlling the drive in a simple manner.
  • the method and the device according to the invention are characterized in that a motor is provided with a first operating mode with high nominal torque and low nominal speed and with a second operating mode with low nominal torque and high nominal speed, by means of an electronic circuit when the motor is switched on for lifting or Lowering the stack, the first operating mode is selected and, after a predetermined period of time after switching on, the system switches to the second operating mode if the rotational speed has exceeded a predetermined value when the stack has been lifted and has not exceeded a predetermined value when the stack has been lowered.
  • the invention takes advantage of the fact that with high stack heights, high torques for the drive are required, but only short distances have to be covered, whereas with a low stack height, less torque is required at higher speeds.
  • the method and the device according to the invention are characterized by little effort. For example, no force sensor is required. Both when lifting and when lowering the stack, an adaptation to the stack height is achieved.
  • a further development of the invention consists in switching back to the first operating mode after a further predetermined period of time if the rotational speed has not exceeded a further predetermined value. This further development ensures that when the stack height for which the second operating mode does not generate a sufficiently high torque is switched back to the first operating mode.
  • An advantageous embodiment of the device according to the invention is that a motor with a switchable winding is provided.
  • the stack lifting device 1 shown in Fig. 1 consists essentially of the stacking table 4 with the actual stack of sheets 5.
  • the stack is raised or lowered via a motor 15 provided with an electronic circuit 6, the drive shaft 19 of the motor 15 with the Wave 3 is connected.
  • the counterweights 2 are provided for tightening the loose chain ends.
  • the electronic circuit 6 connected to the motor 15 is shown in FIG. 2. It is composed of the actual control 7, the power section 8 and the relay 12.
  • the motor 15 has two windings with the inputs U1, V1, W1 and U2, V2, W2.
  • Hall sensors for example, are provided as rotor position sensors 11, the signals of which are routed via lines 18 into the speed detection 9 of the controller 7.
  • Other devices for speed detection are also conceivable, e.g. optical devices.
  • the two windings of the motor 15 are supplied with current via the controller 7, the power unit 8 and the relay 12 for switching the winding.
  • the outputs U, V, W of the power section 8 are connected to the inputs 16 of the relay 12. Furthermore, a line 10 is provided for switching the winding between the controller 7 and the relay 12.
  • FIG. 3 shows the course of the rotational speed n is within a few seconds after the motor 15 is switched on for lifting the stacks 4 and 5.
  • FIG. 3a shows the conditions when the stack height is large, that is to say when the stacks 4 and 5 are heavy , b) with a low stack height and c) with a medium stack height.
  • Operating mode A means high nominal torque and low nominal speed, operating mode B low nominal torque and high nominal speed.
  • the speed n is not reaching the threshold value n gr1 . 2 is therefore not switched over by the circuit.
  • the actual speed n ist exceeds the threshold value n gr1 , so that after 1s a switch is made to a winding for high speeds, whereupon the actual speed n is increased accordingly.
  • the weight of the stacks 4 and 5 is just large enough that in the first operating mode A the threshold value of n gr1 has just been exceeded.
  • the nominal torque of the motor 15 becomes so small that the speed n ist does not exceed the further threshold value n gr2 . In this case, the system switches back to the first operating mode A after a further second.
  • Fig. 4a shows the course of the speeds with a large stack height
  • Fig. 4b shows the situation with a small stack height. If the stack height is large, the speed n ist exceeds the predefined value n gr0 , whereupon the operating mode is not switched over. However, is so small, the weight of the stack is that the speed n n the predetermined value does not exceed gr0, then to the second mode B, namely switching to a winding for high speeds.
