Hanedashi is called a device or means for automatized unload of a work item from one process or operation, providing the correct state for the next item to be loaded. The Hanedashi principle of automatized unloading and orientation for the next process is often used in automated production systems that operate according to the Chaku-Chaku principle.

When designing a machine according to the Hanedashi Principle, the only manual operation is to insert the workpiece. The processing and afterwards the ejection is fully automated, the workpiece than can be transported to the next machine or handed over to the next operator. Meanwhile, the machine automatically returns to the initial position where it can be reloaded.

The conclusion of the Hanedashi Principle: Humans are better for loading and machines are better for unloading. It is that simple to knock it down.
