Not all products are fit to be sold. Products can be rejected by sight for reasons such as an irregularity or deformity, or they may fail a safety test such as metal detection.
It is then necessary to remove the products from the production line. There are a variety of ways to accomplish this including a retracting tail which allows the rejected product to drop onto another conveyor or into a bin to be taken away or diverters, pushers, or gates to manipulate the product route.
Sometimes, product needs to be placed onto another conveyor or a tray in precise rows or columns. A retract conveyor can be equipped with sensors to ensure the product is placed exactly where it needs to be on whether it’s in a box, or on another conveyor.
