A robot is only as capable as its end-of-arm tool. The EOAT — the gripper, the vacuum tool, the mechanism that actually contacts the product — is what determines whether the system picks reliably, places accurately, and runs without dropping product or damaging packages.
In food packaging, this is where one-size-fits-all breaks down completely.
Industrial automation catalogs are full of universal grippers — adjustable vacuum cups, adaptable mechanical fingers, multi-purpose tooling designed to handle a range of product geometries. In warehouse and logistics applications, where products come in standardized boxes and packages, these tools work well enough.
Food is different. A 1-lb sausage chub has a different surface texture, weight, flexibility, and shape than a bacon draft. A blueberry clamshell handles nothing like a block of cheddar cheese. A stand-up pouch of shredded chicken requires fundamentally different vacuum characteristics than a thermoformed MAP tray of sliced turkey.
The surface of the product, its weight distribution, its rigidity (or lack thereof), its temperature, its packaging material, whether it's slippery with moisture or sticky with fat — all of these determine what the EOAT needs to do. A universal suction cup set to a standard vacuum pressure will either grip too hard (deforming the product or damaging the package) or too loosely (dropping the product mid-cycle).
Neither outcome is acceptable at production speed.
Every JLS packaging system ships with end-of-arm tooling designed for the customer's products. Here's how that process works.
The process starts with real product. JLS application engineers request representative samples of the products and formats the system will handle. Weight variations, packaging materials, seasonal differences, and any known product variability are documented.
This isn't optional. You can't design a gripper from a spec sheet. The EOAT design needs to account for how the product actually behaves — how it deforms under vacuum, how its surface responds to different cup materials, how its weight shifts when lifted at speed.
JLS application engineers design the EOAT based on the product samples. This includes:
The EOAT design is validated on actual product before the system ships. During factory acceptance testing at JLS's facility in York, Pennsylvania, the tooling runs against real product at production speed. Pick success rate, placement accuracy, and product condition are measured and verified.
If the tooling doesn't perform to specification on real product, it gets redesigned and retested — before the system leaves York.
For operations running multiple SKUs, the EOAT swap is designed for tool-less changeover. The operator unclips the current tool and clips on the tool for the next product family — no wrenches, no bolts, no vacuum line reconnections. Combined with HMI recipe selection, changeover is designed to be fast and repeatable; actual requirements depend on the formats and tooling involved.
Tooling is designed around a family of products — a single EOAT is often configured to handle a range of related formats, and additional tools cover formats with different handling requirements. The changeover is fast because the tools are designed for quick-change from the start — not because the tooling is a compromise that tries to handle everything with one configuration.
JLS designs custom EOAT for applications across the TALON® primary handling platform and the OSPREY® case packing family:
Every product is different. Every EOAT is designed for the products it handles. That's the point.
