Patent ID: 7896315

Claim:
A control and regulation arrangement for assuring the overload safety of a conveyor apparatus ( 1 ), which comprises: a brake system ( 11 , 11 ′, 18 , 18 ′) which acts upon the conveyor apparatus ( 1 ), a control ( 30 ) for the said brake system ( 11 , 11 ′, 18 , 18 ′), an overload sensor ( 29 ), which detects overload conditions and issues an overload signal, and a speed sensor ( 31 ; 24 , 24 ′) which detects the speed of an object ( 16 ) in transport and issues a signal of the same, whereby the control ( 30 ) reacts upon the brake system ( 11 , 11 ′, 18 , 18 ′) in response to the overload signal in such a manner, that the brake system stops the conveyor apparatus ( 1 ) and thus protects the object in transport ( 16 ), and whereby the control ( 30 ), following a subsequent unloading signal, releases the said stoppage of the conveyor apparatus ( 1 ) to such an extent, that the conveyor apparatus ( 1 ), responding to the weight of the object in transport ( 16 ), enters into an unloading state, and the action of the brake system ( 11 , 11 ′, 18 , 18 ′) restricting the conveyor apparatus ( 1 ) becomes so regulated in keeping with the signal from the speed sensor ( 31 ; 24 , 24 ′) that the object in transport ( 16 ) is caused to move at an approximately constant speed within the said unloading state.
