  • 22. The Box Detection Logic

    Two sets of proximity switches will be used to detect boxes passing by the sizing station.

    Based on the size of the box that passes the station, the system will route the box to the corresponding palletizer.

    The two sets of detection sensors help prevent unnecessary downtime should a box become...

  • 23. Enhancing the Box Detection Logic

    - Using two sets of proximity sensors ensures that boxes are correctly sized and counted, even if a sensor is not functioning correctly. However, this redundancy requires extra programming to ensure a box is not inadvertently counted by both sets of sensors.
    - When a box passes into the sizing ar...

  • 24. Duplicating the Small Box Detecti...

    The logic for the detection of a large box should be very much the same as the logic for the detection of the small box. We assume this is the case, and we create a new rung and edit the new rung to reflect the addresses that are unique to the large box detection.

    When a large box passes through...
