Strongpoint Automation has introduced the Strongpoint End of Arm Tool (EOAT), an automated high-capacity palletiser for RSC cases.

The system incorporates a multiple-product infeed configuration to stage and position incoming products for palletising.

At the heart of the system is a Fanuc M410iB – 160 robot, optimally positioned to place two products on two pallet-locations, in addition to handling multiple pallet styles.

The EOAT helps prevent dropped or misplaced RSC cases in robotic systems.

It is made from extruded components and custom-designed aluminium weldments to reduce and optimise tooling weight.

The EOAT is controlled by a single Devicenet node that manages all pneumatic and I/O requirements.

An optional diagnostic tool can monitor and test all functions of the EOAT node.

The EOAT can handle a range of product weights and sizes without tooling adjustments or changeovers.

The EOAT can handle multiple cases, each exceeding 50lb for a total pick-weight of more than 200lb (90.72kg).

A high-capacity vacuum-pump provides vacuum flows at the cup face not traditionally achievable with venture-style generators.

Because of the 50lb weight and height of the RSC cases, traditional vacuum-based tools were unable to process the case placements at high speed because of the magnitude of the shear loads at the cup face.

Without the use of clamp stabilisation, the loss of cup contact under high accelerations and case drops was inevitable.

To combat these high shear-loads, the EOAT uses pneumatically actuated side clamps operating on the principle of a four-bar linkage.

The actuating geometry of the side-clamp assemblies allows them to automatically adjust for an infinite number of case widths while maintaining the primary clamping-surface perpendicular to the case face at all times.

Customised robotic motions negate large product-moments generated in traditional palletising motions.

The porous nature of the recycled RSC material and high case-weight mandated the need for a high-capacity rotary-lobe vacuum pump capable of drawing 117ft3/min at -28.4in of Hg.

The use of traditional venturi-style generators represented an enormous draw on plant-process air and cost the facility money.

The high vacuum-flow is delivered to the EOAT manifold by a large-diameter flexible hose, the cup groups of which are activated by pilot air actuated high-capacity vacuum valves.

The EOAT can also retrieve pallets from multiple static pallet magazines and places them prior to palletising.

Optional tier and slip-sheet handling is also available.
