Device and method for conveying viscous material

A method for 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 a container upper side, which is open at the container upper side, the method comprising:

• providing an apparatus comprising a follower plate having a material outlet attached to a conveyor pump, wherein the follower plate is provided with an annularly circumferential wiper ring, wherein the wiper ring has a radially outwardly extending contacting part for contact against an inside face, turned toward the follower plate, of the circumferential container wall, and wherein the contacting part can be pressurized with a variable pressing force for pressing against the inside face of the circumferential container wall, wherein the follower plate is mounted by at least one vertically extending retaining rod on a horizontally extending crosspiece, which is mounted on or close to a first end on a lifting device for raising and lowering of the crosspiece, while a second end of the crosspiece is free;
• moving the follower plate in the direction of the container bottom by following a descending material level in a manner resting on a surface of the material and, after emptying of the container, is moved moving the follower plate away from the container bottom;
• pressing the wiper ring, during the movement of the follower plate to the container bottom, sealingly with the contacting part of the wiper ring against the inside face of the circumferential container wall and, during the movement of the follower plate away from the container bottom, a sealing effect between the wiper ring and the circumferential container wall is nullified by reduction of the pressing force;
• wherein, using a control device, the emptied container is automatically transported away after removal of the follower plate;
• and
• wherein, using the control device, a container filled with the viscous material is positioned underneath the follower plate.

An apparatus for conveying viscous material from a drum-like container, which has a container bottom and a circumferential container wall extending from the container bottom to a container upper side and is open at the container upper side, with, for closing of the container, a follower plate having a material outlet attached to a conveyor pump,

• wherein the follower plate is provided with an annularly circumferential wiper ring,
• wherein the wiper ring has a radially outwardly extending contacting part for contact against an inside face, turned toward the follower plate, of the circumferential container wall,
• wherein the contacting part can be pressurized with a variable pressing force for pressing against the inside face of the circumferential container wall,
• wherein the follower plate is mounted by at least one vertically extending retaining rod on a horizontally extending crosspiece, which is mounted on or close to a first end on a lifting device for raising and lowering of the crosspiece, while a second end of the crosspiece is free, and
• wherein the apparatus comprises a transport device for transporting of the container in a direction perpendicular to a longitudinal extent of the crosspiece.
