Collaborative vs Industrial Palletizing Robots: How to Choose

1. Start with the product and end-of-arm tooling

Record the heaviest and largest product, the packaging surface, how it deforms and whether one or several items must be picked together. A carton that holds its shape presents a different gripping problem from a soft filled bag.

The CR catalog includes 30 kg and 50 kg collaborative workstations. Industrial alternatives include compact ECR models and SCH palletizing robots across a broader payload range. These are catalog starting points; tooling mass, load position and the actual movement still need review. A nominal payload by itself does not confirm application suitability.

2. Check the full pallet pattern and stack height

Draw the conveyor pickup point, robot base and every pallet position. Check the far corners, bottom layer and top layer with the real tool and product dimensions. Robot reach is not the same measurement as finished stack height.

All four CR30/CR50 workstation variants list 1,900 mm reach. The L variants add a lifting arrangement with a standard 500 mm stroke. A lift changes the available working positions; it does not change the catalog arm-reach figure. Confirm the whole envelope rather than assuming that a lift solves every clearance issue.

3. Compare complete line output

Use the required products per hour together with the arrival pattern: evenly spaced cartons, short bursts and upstream stoppages lead to different buffering needs. Include pallet exchange, slip sheets where required, recipe changes and recovery after an interruption.

A catalog motion or packing-rate figure should not be treated as guaranteed output for a different product and layout. Ask for a cycle review covering your pickup, placement and pallet pattern before fixing the line specification.

4. Plan operator access and cell integration

Map where operators replenish pallets, remove completed loads and access equipment. Review guarding, interlocks and the robot/tool/load combination as part of the integrated cell. The word collaborative alone does not establish that an application can operate without guarding.

Compare proposals on the same scope: robot and base, gripper, conveyors, pallet positions, controls and operator access. This makes the difference between a workstation proposal and a complete line-integration proposal easier to assess.
