Abstract
A sealing condition monitoring apparatus detects in a real-time manner a defect in of sealing due to entry of foreign matter or due to a defect or malfunction of components of a sealing apparatus. There are provided a counter bar disposed at the forward end of a counter jaw for sealing a packaging container into which a liquid food is charged, and a sealing bar disposed at the forward end of a heat sealing jaw to face the counter bar. A packaging material is held between the sealing bar and the counter bar, and a pressing force is applied thereto for sealing. A sheet-shaped pressure sensor is provided on the surface of the counter bar for detecting the pressing force applied to the packaging material at each detection point. Also, there is provided a controller which compares data of the pressing force detected by the sheet-shaped pressure sensor and master data which are previously set to correspond to a pressing force for obtaining proper sealing conditions. The controller detects a defect in sealing by comparing the data for detected pressing force with the master data.
