Abstract
A vacuum lifter for moving loads with adhesion surfaces comprises at least one suction head with several annular seals projecting from its suction side and forming vacuum spaces enclosed by said seals, said vacuum spaces communicating with a vacuum source , the vacuum source communicating through valve(s) with the outer vacuum space(s), said valve(s) being controlled each by sensors detecting the magnitude of the adhesion surface of the load.
In order to always prevent impulsive detachment and especially unwanted renewed lifting of the load after it was deposited, a compressed-air system 51, 52, 53 is associated to at least one of the vacuum spaces 13 and a control system is provided which turns ON
for a specified time the compressed-air system following detection of interruption of the connection to the vacuum source 16 and following venting of this vacuum space 13, a blocking valve 22 being provided to interrupt venting.
