Abstract:
1. A leakage-detecting device for sealed packages comprising: a conveyor belt that continuously moves sealed packages that have been filled with detection gas for detecting leakage; a work-removal apparatus; and a leakage-detection unit that is located along the conveying route of the conveyor and that detects leakage from said sealed packages; and wherein said conveyor belt comprises an input conveyor and an output conveyor; said leakage-detection unit comprises: a vibration-application means that applies vibration to the detection gas inside said sealed packages and a gas-detection means that detects detection gas that leaks from said sealed packages; and wherein said vibration-application means is a striking apparatus that strikes the sealed packages on said conveyor belt; and said striking apparatus further comprises: a bracket that is installed above said conveyor belt; a pressure plate that is attached to said bracket by way of a link, and the pressure plate strikes said sealed package by up and down movement of the pressure plate; and said gas-detection means comprises: a box that forms a detection space around said vibration-application means and conveyed sealed packages; a probe that is located in this box and draws in gas from inside said detection space, and a gas detector that is connected to this probe; a blower which connected to said box, sucks in the gas from inside the box and discharges it to the outside.
