Machine loading and unloading by industrial robots

In machine loading and unloading process, a robot will be used to move the work parts to or/and from the production machine. This application comes under the category of material handling operations.

The machine loading and unloading application includes the following three processes:

  • Machine loading
  • Machine unloading
  • Machine load and unload

Machine loading:

In this operation, the robot loads raw work parts in the machine, and some other systems are used to unload the finished work parts from the machine.

Example: In a press working process, a robot is used to load the sheet metal in the press, and the finished work parts are removed from the press with the help of gravity.

Machine unloading:

In machine unloading, the finished work parts are unloaded from the machine by a robot, while the loading of raw materials are done without any robot support.

Example: Plastic modeling and die casting.

Machine load and unload:

In this process, a robot performs both loading and unloading of work parts in and from the machine.

Example: Machining operation.

The machine loading and unloading process performed by industrial robots are very well characterized by the robot-centered workcell. This cell includes a robot, production machine, and other devices like part delivery system. It helps in increasing the usage of a robot by making it to service more than a production machine. As a result, the productivity in the cell is also increased to a larger extent. This robot cell can be preferred when a robot is in the idle state for a long time.

Moreover, the robots are largely used to carry out loading and unloading process in some production operations like forging, die casting, plastic modeling, stamping press, and machining operations.
