Monitoring In-Line Accumulation on a Single Filer
Monitoring clear bottles as they are removed from a depalletizer and progress through a single filer can be challenging. The transparency of the targets and the unstable signal from the movement of the bottles can be difficult for many sensors to detect reliably. Learn how the Q5X laser distance sensor solves this application.
When bottles are removed from a depalletizer the bottles are swept off of the pallet by a sweeper arm, layer by layer. The bottles eventually start to move into a single file and continue downstream. It is important to monitor the bottles in the staging area to make sure that they have moved on before another layer is swept onto the conveyor. However, the unstable signal from the moving bottles and low contrast objects, can be challenging for sensors to detect reliably.
The Q5X background suppression sensor detects when the staging area is clear of bottles, and the system is ready for the next layer of containers. The integral timing delay on the Q5X filters out any small gaps between objects as they move in a cluster.
The background suppression function of the Q5X is also important in this type of environment because the sensor can be set to only detect objects within a defined sensing field and ignore anything that is located beyond the sensing field cutoff point.
Also, in dual teach mode—which measures both distance and light intensity—the Q5X can reliably detect the presence of clear bottles without the risk of double counting. Learn more about Banner's solutions for clear object detection.
