When robots start to feel: HBK and Siléane bring tactile intelligence to high-speed cosmetics packaging

France-based robotics specialist Siléane has partnered with HBK on an automated gripping system for a global cosmetics manufacturer. The system targets fast, high-volume packaging operations where robots must handle lightweight, flexible parts with narrow tolerances, including deformable thermoformed trays. Conventional robotic systems provide speed, repeatability, and execution, but lack tactile feedback. As a result, poorly balanced grips can damage trays or cause product losses, while position tracking and binary detection provide limited evidence of the actual contact quality.

Siléane chose to put force sensing inside the end-of-arm tool rather than add external inspection stages. The gripper incorporates four factory-calibrated HBK PW22i smart load cells, with one installed at each contact point. Using IO-Link connectivity, the sensors collect force data during every gripping cycle, allowing the robot to assess grip quality at its source and react to physical deviations immediately. The configuration is intended to fit modern automation architectures while avoiding a more complicated inspection arrangement.

HBK developed the PW22i from its PW22 load cell, which had been used in high-speed dynamic weighing applications such as checkweighing and filling. The newer model adds IO-Link connectivity for integration needs.

According to the article, the installation gives the customer real-time validation across all grip contact points and aims for zero-defect grip validation. Reported benefits include reduced product scrap and tray deformation, less cabling through IO-Link, simpler system architecture, quicker commissioning, and more repeatable installations. These operational improvements are presented as supporting faster return on investment.
