Mention “manufacturing automation” and most people picture an assembly line or a manufacturing cell, the places where parts are joined and products take shape. But automation doesn’t end there. End-of-line automation represents the critical phase of production that occurs after a product has been fabricated or assembled.
As a primary segment of industrial automation, end-of-line solutions are increasingly becoming the first place where companies look to automate. Why? Because the tasks are often repetitive, physically demanding, and—most importantly—low risk with high demand. By transitioning from manual, mindless work to a streamlined, automated finish, manufacturers can ensure higher quality while reallocating human labor to tasks that require more nuance and skill.
End-of-line automation is far more than just putting items in a box. It is a modular sequence of events that can be implemented as a full turnkey system or in smaller subsets depending on a facility’s needs. Here are six ways to automate tasks at the end of your production line.
One of the first steps in this sequence is direct part marking and labeling. This involves identifying products with barcodes or 2D data matrices for complete manufacturing traceability. Marking methods typically include:
Another end-of-line production step that’s ideal for automating is inserting hardware and instructions with 100% accuracy. Production workers easily miss a sheet or include the wrong hardware packet, but automation ensures these items are included every time. In some cases, integrators use ionizers to create static, “sticking” the instruction sheet to the product right before it enters the shrink wrap.
Following identification, the process moves to case erecting, filling, and sealing. Automation and robotics are used here to form boxes from flat stacks, insert products with precision, and seal them for transport. For specialized applications, companies may utilize advanced options like wrap-around case formers or bag-in-box systems, where a bag is filled, sealed, and then placed inside a protective outer box.
Depending on the product, standard boxing might not be enough. End-of-line automation often includes specialized plastic wrapping techniques:
Palletizing is often considered the most commoditized and straightforward entry point for companies new to automation. Because the technology is mature, it is a relatively low-risk undertaking that offers immediate benefits in speed and safety. High-speed palletizers can even pick up entire rows of product at once, far outperforming the pace of manual labor.
To ensure these pallets reach their destination safely, load stabilization is vital:
Automation brings a level of precision to quality control that manual processes cannot match. Precision counting is essential in industries like medical and dental manufacturing, where an exact number of parts (often hundreds) must be verified before a container is shipped out.
Smart sorting is another high-value application. In plants running multiple SKUs simultaneously, automation can identify different products and sort them onto dedicated areas prior to palletizing. This can be a massive space-saver because, rather than having multiple active pallets being loaded simultaneously, the system can sort and collect items until a pallet’s worth is ready to be loaded, then palletize. Throughout this entire process, data integrity can be maintained by carrying lot codes and manufacturing dates through RFID or barcode scans.
The shift toward EOL automation is driven by three primary factors:
When considering an end-of-line project, start small. You do not need to automate your entire line at once. Begin with a subset, like palletizing, and expand in phases. Just make sure you know your end goal before starting so that the equipment fits within your facility’s footprint and integrates seamlessly with upstream data.
One common misconception you must avoid is the idea of “lights out” automation. Even the most advanced automated lines typically require a machine operator to be in the area to help the system recover when minor problems occur.
The success of an end-of-line system often comes down to the experience of the integrator. Veteran integrators bring years of experience and lessons learned from past failures, which allow them to make better engineering decisions. Working with a dedicated partner ensures you benefit from specific expertise in custom solutions.
Are you ready to optimize your production? Now is the time to audit your current manual end-of-line processes and identify the areas where automation provides the highest return on investment. Whether it’s a single palletizing cell or a comprehensive end-of-line system, the path to a more efficient, safer, and more profitable floor starts at the end of the line.
If you need an integrator to help you manage the implementation, let’s talk.
In contemporary manufacturing, the push to automate processes is often driven by a need to increase precision, speed, and reliability. The processes don’t have to be particularly complex to make automation a challenge. Consider screw driving, for example.
In the world of industrial automation, manufacturers often seek ways to increase throughput and reduce labor costs. But jumping into automation without a clear roadmap can lead to significant hurdles.
