US 6,207,337 B1 · Immersion coating system

Abstract

A material handling system for dip coating at least a first drum having a first predetermined length in a first coating cycle and a second drum of a second different predetermined length in a different coating cycle including a carrier device for carrying at least one drum, a coating bath container for depositing a layer of coating material onto at least one drum, a mechanism for raising and lowering the coating bath container between at least a first position and a second position higher than the first position, and a transport device for vertically transporting the carrier device a first predetermined distance from a home position for the first drum and a second predetermined different distance from the home position for the second drum, the first predetermined distance from a home position for the first drum and the second predetermined different distance from the home position for the second drum being sufficient to at least partially insert the first drum and second drum, respectively, into the coating bath container while the coating bath container is stationary. A process for coating the drums is also disclosed.

A process for dip coating at least a first drum having a first predetermined length in a first coating cycle and a second drum of a second different predetermined length in a different coating cycle comprising:

in the first coating cycle
positioning at a first location a coating bath for depositing a layer of coating material onto at least one drum,
vertically transporting at least one first drum having a first predetermined length a predetermined first distance from a home position to bring the first drum into contact with the coating bath,
vertically transporting the first drum back to the home position;
and then in the different coating cycle
positioning at a second location the coating bath for depositing a layer of coating material onto at least one drum,
vertically transporting at least one second drum having a second different predetermined length a predetermined second different distance from the home position to bring the second drum into contact with the coating bath, and
vertically transporting the second drum back to the home position, the first predetermined distance from the home position for the first drum and the second predetermined different distance from the home position for the second drum being sufficient to bring the first drum and second drum, respectively, into contact with the coating bath while the coating bath container is substantially stationary.
