Title:
包装体の製造装置及び包装体の製造方法
Document Type and Number:
Japanese Patent JP6679686
Kind Code:
B2
Abstract:
There is provided a manufacturing device of a package or the like configured to perform an inspection for the good/ poor quality of sealing with higher accuracy. In the state that a predetermined work is packed with a sheet 3 made of a resin, overlapping parts of the sheet 3 are thermally welded to form a sealed portion 6. This thermal welding is performed such as to make the thickness of the sealed portion 6 smaller than the total thickness of the overlapping parts of the sheet 3 as an object to be thermally welded prior to thermal welding. An inspection of the sealed portion 6 obtains thickness information corresponding to the thickness of the sealed portion 6 and determines the good/ poor quality of sealing with regard to the sealed portion 6, based on the obtained thickness information. The thermal welding is performed such as to correlate the good/ poor quality of sealing to the thickness of the sealed portion 6. The configuration of performing the good/ poor quality judgment based on the thickness information enables the good/ poor quality of sealing to be determined with the higher accuracy.
