Schmalz Compact Vacuum System: Flexible Palletization

Schmalz's Solution

In collaboration with Schmalz, the company designed a compact, collaborative robot with a vacuum palletizing gripping system to fit United Symbol's limited space. The system maximizes functionality in a minimal amount of space. It integrates Schmalz's vacuum automation technology into a collaborative robotic platform. It can handle multiple box formats and weights and supports both Euro pallets (800 × 1200 mm) and 1000 × 1200 mm pallets. It can also execute complex palletization patterns, including vertical positioning. Cardboard interlayers also integrate seamlessly into the workflow. Maintaining operator access between tightly-spaced production lines was critical to implementation. Schmalz engineered the system to require no modifications to existing infrastructure, eliminating costly retrofitting while delivering the full benefits of automation. Installation and commissioning were completed in one day, and full operator training was completed in an additional half day. This rapid deployment minimized production disruption. United Symbol's engineering team developed custom software in collaboration with Schmalz to maximize operator autonomy and reduce dependency on external resources for configuration and ongoing adjustments. The design prioritizes accessibility. Pneumatic components remain fully accessible for maintenance. Protective covers prevent controller contamination. The lightweight gripper with Compact Ejectors SCPLc and Bellows Suction Cups SPB1 maximizes load capacity efficiency. This solution delivers faster order processing, reduced cycle times, and increased productivity across 25 production lines. Positioning precision has significantly improved, reducing errors and material waste. Most importantly, operators now work in optimal ergonomic conditions, which directly addresses the core health objectives driving this automation investment.
