AI Technical Summary

Technical Problem

In the prior art, damage or improper installation of the partition components of the filling valve or sealing device can prevent the sterile area from maintaining a sterile state. Moreover, the inspection process requires disassembling the equipment one by one, which is time-consuming and makes it difficult to detect poor sealing.

Method used

The partition anomaly detection system is adopted, which supplies detection medium to the functional units through the medium supply unit. It detects partition anomalies by utilizing the medium leakage in the enclosed space. The system includes functional units such as filling valves, sealing devices, and capping machines, enabling the detection of partition anomalies without disassembling the equipment.

Benefits of technology

It improves the productivity of the aseptic filling system, reduces maintenance costs and human error, ensures the sterility of the aseptic area, and improves the product qualification rate.

Abstract

By providing a system and method capable of easily grasping an abnormality that can occur in a partition wall for aseptic filling, maintenance costs of an aseptic filling device are suppressed, and productivity is helped to be improved. The partition wall abnormality detection system is provided with: an aseptic area in which discharge portions of respective filling valves are located; a non-aseptic area; a functional unit selected from at least one of a plurality of closure devices, a plurality of filling valves, and a plurality of head caps; and a medium supply portion configured to supply a detection medium for detecting a related abnormality of a partition wall included in the functional unit to the plurality of functional units. A closed space constituted by the partition wall retains the detection medium supplied by the medium supply portion in the absence of an abnormality and causes the detection medium to leak in the presence of an abnormality.
