Control system for continuous vulcanization line for manufacturing sponge rubber product.

摘要

A control system for automatically controlling a continuous vulcanization line for manufacturing sponge rubber products, comprises sensor means for monitoring an outside dimension of a sponge rubber product produced by the continuous vulcanization line, a discriminating circuit for determining whether the monitored outside dimension is within a predetermined criterion defined by designated upper and lower limits of an acceptable rubber product, an arithmetic circuit for deriving an offset amount of the outside dimension, offsetting from the criterion, and a control circuit for controlling an output power of microwave generated by a microwave vulcanizer employed in a primary heating system for pre-foaming a sponge rubber material, depending on the offset amount of the outside dimension.
