Device for conveying viscous material

Abstract

The invention relates to an apparatus () for the conveying of viscous material from a drum-like container (), which has a container bottom () and a circumferential container wall () extending from the container bottom () to an upper rim () of the container, which is open at the upper rim () of the container, the apparatus having, for closing of the container (), a follower plate () having a material outlet () attached to a conveyor pump (), wherein the follower plate () can be moved up and down in the container () while being in sealing contact against an inside face of the container wall () turned toward it, and having a lifting device () for raising and lowering of the follower plate (), wherein the lifting device () has a drive unit. According to the invention, a protective device () having a protective member () is provided, which is disposed in such a way with respect to the follower plate () and the container () that, upon introduction of the follower plate () into the container (), it annularly surrounds on the one hand the follower plate () and on the other hand the container () in the region of the upper rim () of the container. The protective device () additionally has at least one switch () for switching-off of the drive unit upon an at least partial exposure of the upper rim () of the container by the protective member () during the introduction of the follower plate () into the container ().
