Unloading unit

Unloading unit on CNC-machining centres are especially used in the Nesting processing.

Usually the unloading unit has two functions:

  • Cleaning the nested panels
  • Unloading the ready-nested workpieces onto a delivery belt.

Construction and function:

Mostly it's a small intake duct which is robustly constructed and can reach over the entire machine width. On the unloading side a changeable layer is put on in order to both save the panel as well as the duct. In the first cycle the suction duct goes barely over the nested panel and thus removes woodchips and dust.

In the second step the duct moves along the narrow side of the panel, lowers and moves the ready-nested workpieces onto a conveyor belt which moves them away completely from the machine table. Thus the table is free again to be occupied with a new panel. Many machines have coupled unloading units with feeding units. This draws automatically a new panel (e.g. from a feed roller conveyor or from a lifting table) onto the machinetable. With such combination the nesting process can take place automatically without the operator having to intervene when handling the panels.
