Definitions

  • the invention relates to a vibrating device with a vibrating table, with unbalanced shafts arranged in the vibrating table, driven and each provided with an unbalance body, which are assigned to one another in pairs, and with an adjusting device by means of which the vibrating frequency and the angular position of the unbalanced bodies can be changed relative to one another.
  • An adjustable and controllable vibrating device of the type mentioned serves the purpose of optimally compacting concrete elements during their production. This is achieved by program-controlled adaptation of the operating parameters of the vibrating device to the product-specific requirements during the production process.
  • the invention is based on the object of carrying out the adjustment of the operating parameters required to produce the optimum vibrating effect in accordance with a new principle in a vibrating device of the type mentioned at the outset.
  • this object is achieved in that each unbalanced shaft is driven individually by a motor which rotates at a predetermined speed in synchronism with the other motors, and an electronic controller is provided as an actuating device, by means of which each motor can be controlled in an angle-synchronized manner so that to change the vibrating frequency, the rotational speed of the unbalanced shafts and to change the angular position of the unbalanced bodies relative to one another, the rotational speed of at least one of the two mutually associated unbalanced shafts can be changed briefly.
  • the synchronization of the individual unbalance shafts is achieved by electronic, angularly synchronous control of the unbalance drives.
  • the intensity of the vibrating effect is controlled by an electronic change in the rotor position angle of the individual unbalance drives.
  • Each unbalanced shaft W1 to W4 is individually driven by one of the motors M1 to M4.
  • the motor M1 to M4 runs at the specified speed in synchronism with the other motors.
  • An electronic controller is provided as an adjusting device, by means of which the vibrating frequency and the angular position of the unbalance bodies U1 to U4 can be changed. Via the electronic controller, each motor M1 to M4 can be controlled in an angle-synchronized manner so that the Vibration frequency, the rotational speed of the unbalanced shafts W1 to W4 and to change the angular position of the unbalanced bodies U1 to U4 relative to one another, the rotational speed of at least one of the two mutually associated unbalanced shafts W1 to W4 can be changed briefly.
  • the unbalance bodies U1 to U4 of unbalanced shafts W1 to W4 assigned to one another have an angular position of 180 ° to one another.
  • motors M1 to M4 Via one of the two mutually assigned unbalanced shafts W1 to W4, motors M1 to M4, the one unbalanced shaft is briefly driven at a reduced speed, after reaching the desired new angular position which deviates from 180 °, again at the same speed as the motor driving the assigned unbalanced shaft.
  • the motors M1 to M4 are controlled via the motor control circuits K1 to K4 and the rotor position controller 2.
  • the rotor position control is superior to the motor control circuits K1 to K4.
  • Each motor M1 to M4 is assigned one of the mechanically coupled resolvers R1 to R4 and, as part of one of the motor control circuits K1 to K4, one of the drive inverters A1 to A4.
  • the drive converter A1 to A4 changes the speed of the motor M1 to M4 depending on the output signals sin ⁇ t and cos ⁇ t from the resolver R1 to R4 and setpoint signals from the rotor position controller 2 via the operating frequency f.
  • Actual values of the rotor positions of the motors M1 to M4 and operating parameters are fed to the rotor position controller 2 from the motor control circuits K1 to K4.
  • the operating parameters include, for example, the desired angle, vibrating time and actuating time.
  • the invention can be used commercially in the production of concrete elements that are compacted.
