Definitions

  • the invention relates to a method for operating a bell ringing machine with a reversible drive motor for a pendulum-driven bell and with a control device which switches the drive motor on and off over variable time or distance sections during one or both half-vibrations of the bell, after the ringing the steady state of the bell is maintained by reducing the electrical energy supplied to the drive motor by shortening the duty cycle or the switch-on distance per vibration.
  • This object is achieved in a method for operating a bell ringing machine of the generic type according to the invention in that a setpoint for the swing-out angle is specified for the steady-state condition, upon reaching which the vibration energy required to hold the swing-out angle setpoint is determined and then the the drive motor supplied reduced electrical energy is set and that the loss energy of the oscillation system per oscillation or half-oscillation is determined from the difference ⁇ 2 of the last swing angle ⁇ , which the bell reaches when the upturn phase ends, and the next, however, reduced swing angle ⁇ , which the Bell reached after undergoing a drive-free, half or full vibration before setting the stop state.
  • the particular advantage of the invention is that when the setpoint of the swing-out angle is reached, the engine is fed only that power loss that is required in the respective operating condition in order to maintain the predetermined swing-out angle. This is irrespective of the size of the excess energy that is supplied to the drive motor during the high-heat phase in order to quickly ring the bell to a predetermined swing-out angle.
  • the determination of the energy loss or the differential energy that must be withdrawn from the engine during the transition from the high-wave phase to the steady state can be determined indirectly via the respective swing-out angles, which result under the conditions below and which are stored, processed and stored in a conventional computer can be converted into control variables for the drive motor.
  • the angle actually reached and the swing-out angle reached in the previous half or full swing are determined and stored.
  • a difference quantity is then formed from these two angles, which is proportional to the energy difference which results from those energies which have been supplied to the oscillation system in the last period under consideration and the previous, penultimate period.
  • this energy difference is reflected in an increase in the potential energy through height gain, although part of the energy difference is consumed by the losses of the vibration system.
  • the difference between the maximum swing angle and that of the previous swing angle is proportional to the sum of the energy loss and the potential energy supplied to the vibration system during the last period and can be used accordingly as a control or manipulated variable.
  • This angle difference can be evaluated directly as an operation variable for the control of the drive motor; however, this quantity can also be related to the angular difference described above, in order to be able to eliminate the potential energy supplied to the system from the energy difference proportional thereto, in order to then reduce the electrical energy supplied to the drive motor in order to cover the losses let the steady system swing with the set point of the swing angle.
  • the on-time or the on-travel for the drive motor which is defined per period for the up-phase, can be reduced in relation to the swing-out angle difference, which results from the last period of the high-rise process, in relation to the swing-out angle difference when changing to the holding state , which is determined in the inserted idle phase.
  • this presupposes that the drive motor is operated with at least approximately constant power during the switch-on phases, which is the case with bell-ringing machines in which the bell is driven by an asynchronous motor which is coupled without slip usually is the case.
  • the electrical energy supplied to the system per half-oscillation or oscillation is reduced to the extent that potential energy for obtaining a higher swing-out angle is no longer supplied to the bell and the achieved swing-out angle is maintained while covering the losses.
  • the invention is further explained below with the aid of a calculation example.
  • the drawing shows schematically the pendulum system of a bell with the associated swing angles.
  • the drawing clarifies those swing-out angles that arise at one of the reversal points of the bell path when changing from the high-tide phase to the steady-state stop.
  • the bell should reach the setpoint ⁇ of the swing angle.
  • the bell In the last oscillation period before the target value ⁇ is reached, the bell only reaches the swing-out angle ⁇ 1. During the last oscillation period in the high-noise phase, so much energy is supplied to the oscillation system that the oscillation angle ⁇ 1 increases by the difference angle ⁇ 1.
  • the swing-out angle decreases from the value ⁇ to the value ⁇ 2 during the idle period.
  • the difference the swing-out angle during this period is ⁇ 2.
