Filling bottles or similar containers with liquid - involves measuring bottle shape or related dimension to eliminate shrinkage errors

摘要

A fill element (3) has a liquid valve and an actuator (12) which is activated at the end of a filling phase to terminate the delivery of filling material. The filling phase contains a correction filling step taking account of a correction parameter generated by an electronic controller (17). The shape of each container (5) and/or at least one typical dimension is detected by a test device (13,13') and the correction parameter is formed according to the output signal of the test device. ADVANTAGE - Highly accurate filling of bottles or similar containers with liquid without certain disadvantages of conventional techniques, e.g. errors caused by plastic bottle shrinkage.
