Abstract
A conveying installation with a linear motor drive including a stator placed along a travel path and at least one conveyor unit guided along the stator in a constrained manner. The stator is divided into a plurality of stator portions. To each stator portion is assigned a braking device whose operation is dependent upon the current supply to a stator. The conveyor units are guided spaced apart by a predetermined distance. If the current supply fails, the braking devices are actuated and stop the movements of the conveyor units.
Claims10
A conveying installation with a linear motor drive, comprising a plurality of stator portions placed one behind the other along a travel path and at least one conveyor unit with at least one permanent magnet, the conveyor unit being guided along the stator portions in a constrained manner, each conveyor unit having braking surfaces, and each stator portion including at least one stationary braking device which is capable of interacting with the braking surfaces of the conveyor units.
