It is forced. In order to automate these operations, there is a problem that the equipment becomes complicated and expensive because it handles many types of luggage having different shapes, weights, physical properties, etc. Even if technically possible, it is economical. It is often difficult to realize.
Therefore, at present, these operations are entrusted manually. For this reason, there is a risk of falling luggage, and there is a problem of causing tendonitis, low back pain, chronic fatigue and the like of workers.

An apparatus for setting a heavy object on a machine and inverting it instead of a human hand is disclosed in Patent Document 1.
Patent Document 2 discloses a device that raises and reverses a heavy cylindrical container such as a drum can.
