Workstation description
The workstation represents a fragment of an automated production line, the main task of which is to separate damaged elements (detection of a damaged element is simulated with an appropriate button in the 'panel' area of Simultus).
Description of the project operation (attached control program)
The exemplary program’s task is to move elements from a container one by one to where they will be pick-up by the manipulator. After an element is detected by a sensor, it is moved by the manipulator to the front of a ramp. The object is then pushed onto the ramp, within which the following is performed:
- detection of damaged elements
- rejection of damaged elements
- counting elements
Detection of a defective element is simulated with the 'DAMAGED ELEMENT' button. After detecting two defective elements in a row, the line is stopped (operation is resumed by pressing the 'START' button). After the passage of four correct elements, the basket is transported by a roller conveyor to the warehouse. Pressing on the EMERGENCY STOP button causes the line to stop in an emergency (the line resumes its operation after the EMERGENCY STOP button is turned off).
Control
 |
'START' button initiates execution of the control program. 'DAMAGED ELEMENT' button simulates the detection of a damaged element on the production line. 'HOME' button causes the homing of actuators and the manipulator. 'EMERGENCY STOP’ initiates the emergency stop routine |
