Description

  The present invention relates to an opening arm for opening a package, and an apparatus for discharging contents from the package including the opening arm, and in particular, chicken packaged in a vacuum state in which air is deaerated. The present invention relates to a product that can cleave other food packages and discharge the contents.

  Conventionally, when selling chicken and other foods at supermarkets and other stores, vacuum-packed chicken and other foods are opened from the package and refilled into individual trays. The work is mainly done manually, and a cutter is used as the means for opening the vacuum package, and the worker is careful to open and open only the package without damaging the contents. .

  On the other hand, as a device for opening a package containing powder that is not suitable for manual operations by workers, the package is supported using a bag opening robot arm, and the contents are discharged by cleaving with a cutter. Techniques are known (see, for example, Patent Documents 1 and 2). Since the robot arm for opening the bag discharges the contents such as powder, the package is supported by the cutter from the lower side and the package is pierced and fixed with a skewer or a needle. After cleaving, the contents are discharged by rotating the arm.
