Description

  The present invention relates to an apparatus for opening contents from a sealed bag. Various materials are filled and sealed in a bag-like material, and are further transported in a state of being accommodated in an outer container. For example, a tomato processing factory is loaded with about 200 kg of tomato paste filled and sealed in a polyethylene-aluminum composite flexible packaging bag and further contained in a drum can. In recent years, a tomato paste of 1 ton or more is filled and sealed in a similar composite soft packaging bag, and further stored in a wooden box. When using such tomato paste as a raw material to produce processed foods such as other processed tomato products, it is necessary to first open the tomato paste from the above-mentioned composite soft packaging bag filled and sealed. is there. The present invention relates to an apparatus for opening contents from a sealed bag represented by opening of tomato paste as described above.

Conventionally, as a device for unpacking the contents from the sealed bag, the sealed bag filled with the contents is transferred onto a receiving tray by a conveyor, the bottom surface of the sealed bag transferred onto the receiving tray is cut with a knife, and then continuously with a pressing head. There is known a technique in which the contents are opened by pressing, and an empty unsealed bag after the contents are opened is held and released by a pressing head by air suction (see, for example, Patent Document 1). ). However, such a conventional opening apparatus is effective when the contents are easily opened like plasma and the content is about several hundreds g to several kg at most. In the case where the contents are difficult to open like a tomato paste, and the content is more than several hundred kg to 1 t, it is extremely difficult due to the mechanism of the device, There is a problem that it cannot actually be applied.
