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.

Abstract: To simplify the operation of an input unit of a filling apparatus and achieve accurate filling of packaging containers with a liquid food. The filling apparatus includes a read-out unit which reads out packaging material information from a magnetic recording medium layer mounted on the packaging material, a sealing unit for sealing the packaging material, and a filling unit for charging the liquid food supplied thereto. Also included is a filling unit controller, which outputs control signals to the sealing unit and the filling unit in accordance with a predetermined program based on the packaging material information and liquid information sent from the read-out unit. The filling apparatus reads out necessary packaging material information from the magnetic recording medium layer at the time of filling, and charges the liquid food in accordance with the packaging material information and liquid information, and seals the packaging material.
