A planing device and a method for activating a planing device, with a mining planer reversibly moveable by means of a planer chain, with at least two chain drives having variable-speed drive motors, with a planer travel measurement system and with a motor control device which, for example by position control, delivers activation parameters for a change in rotational speed of the drive motors for changing the planing speed and which is assigned a control modulewith automatic load compensation regulation between the drive motors. A monitoring module is provided, which, for example by position control, switches off the control module for load compensation regulation or modifies its operating mode and delivers different activation parameters to the drive motors.

Planing device and method for activating a planning device

The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. The invention proposes to filter out a detection signal (S ), representative of the currently arising vibrations of the chain ( ), from the operating data of the main and auxiliary drives (I, II) by means of a detection device ( ), and to take this to an active suppressor ( ), which generates a time-variable control signal (S ) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g. (S ) for the closing pressure adjustment of a multiple disc clutch ( ) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain ( ).
