The application described in this document is used for sticking labels on boxes.
The boxes are carried on a conveyor. A label is stuck onto the box when the latter passes by the two dedicated points.
A sensor placed below the conveyor detects any new incoming box. The boxes should arrive at constant intervals.
The conveyor motor is fitted with an encoder connected to a counting input module. Any process deflection is monitored and displayed.
The application's control resources are based on an operator screen displaying all box positions, the number of labeled boxes and the deflection monitoring.
This is the application’s final operator screen:
The operating mode is as follows:
-
A Start button is used to start the labelling process.
-
A Stop button interrupts the labelling process.
-
When the box arrives at the right time, the Box on time indicator lights on.
-
In case of process deflection, the box delay time is displayed. If this time has been too long, a Process deflection indicator lights on.
