Abstract
An installation for coating objects with a powder, in particular for powder painting, comprises a booth, in which powder can be applied to the objects, a recovery device for the excess powder, which does not adhere to the objects during coating, a storage container for fresh powder and a mixing container, which can be supplied with excess powder from the recovery device and fresh powder from the storage container. A screening machine is arranged in the immediate vicinity of the mixing container, preferably directly beneath the latter, and serves at the same time as an application container, in which mixed powder can be temporarily stored for removal by the application device. The screening machine is not subjected to any low-frequency vibrations, so that a weighing device, which continuously measures the weight of the screening machine, measures the instantaneous consumption of mixed powder in real time. From the stored data, an unambiguous correlation between the quantity of powder dispensed at a particular point in time and the object coated at the point in time in question is possible, so that in the event of faults in the coating operation any defective objects can be determine…
