Function overview

1.1.
The tracking function has the following two functions: the high speed and accuracy tracking function, which
allows robots to follow workpieces on a conveyer with high speed and accuracy, and the circular arc tracking
function, which allows robots to follow workpieces on a turntable and a circular arc conveyer. These functions
enable the workpieces to be transported, lined up, and processed without having to stop the conveyer.

What is high Speed and Accuracy Tracking Function?

1.1.1.
High speed and accuracy tracking function allows a robot to follow workpieces moving on a conveyer with high
speed and accuracy. With this function, it becomes possible to transport, line up and process workpieces
without having to stop the conveyer. It also eliminates the need for mechanical fixtures and so forth required to
fix workpiece positions.
The features of this function are described below.
1) It is possible to follow lined-up workpieces moving on a conveyer while working on them (conveyer
tracking making use of photo electronic sensors).
2) It is possible to follow workpieces that are not in a line moving on a conveyer while working on them, even
in the case of different types of workpieces (vision tracking combined with vision sensors).
3) It is possible to follow changes of movement speed due to automatic calculation of conveyer movement
speed.
4) It increases in the conveyance ability about 15 % (The ratio of our company) compared with the
conventional tracking function.
5) The tracking function can be easily achieved by using Mitsubishi's robot command MELFA-BASIC V or
MELFA-BASIC VI.
6) System construction is made easy by use of sample programs.

What is the circular arc tracking function?

1.1.2.
The circular arc tracking function allows robots to follow workpiece on a turntable and a circular arc conveyer.
With this function, it becomes possible to transport line up and process workpieces without having to stop the
conveyer. It also eliminates the need for mechanical fixtures and so forth required to fix workpiece positions.
The features of this function are described below.
1) It is possible to follow lined-up workpieces moving on a turntable and a circular arc conveyer while
working on them(conveyer tracking making use of photoelectronic sensors)
2) It is possible to follow changes of movement speed due to automatic calculation of conveyer movement
speed.
3) The tracking function can be easily achieved by using Mitsubishi's robot command MELFA-BASIC V or
MELFA-BASIC VI.
4) System construction is made easy by use of sample programs.
