Choosing the right rejection mechanism is important to ensure non-compliant products are accurately removed from the production line.
In addition to implementing advanced product inspection technology to identify any quality issues, manufacturers must also have automated systems in place to efficiently remove non-complaints products. However, there are various types of reject devices, and selecting the appropriate one for a specific application is crucial to ensure non-complaints products are eliminated.
To determine the most suitable option, manufacturers should consider several factors, such as:
It is also important to install a conveyor speed encoder to manage the timing of the rejecter and ensure the accurate removal of non-compliant products.
In certain situations, when a non-conforming product is rejected, it may be advisable to consider re-processing it (instead of disposing). In these instances, instead of using rejection systems, products redirection systems can be used to divert the rejected product for secondary inspection or additional processing.
