This disclosure describes a vacuum gripper array incorporating per-pad isolation to prevent system vacuum collapse when engaging loads with varying porosity or incomplete coverage. The arrangement utilizes individual check valves for each gripper pad, a vacuum reservoir, and a control unit. It details how the system acquires, holds, and releases loads, including mechanisms for detecting uncovered pads and a controlled release sequence to mitigate load displacement. This design addresses the challenge of reliably handling loads where one or more gripper pads might experience significant leakage, which typically compromises the entire vacuum system's integrity.

This disclosure describes a layer transfer head designed to handle full layers of unstable packages, such as cartons or bags. The head incorporates independently retractable side clamps with compliant clamp faces and a layer height sensing mechanism. This configuration prevents layer collapse during transfer and release by ensuring even pressure application and a controlled, sequenced release of the outermost packages. The system addresses the common problem of load instability when rigid or unevenly releasing clamp heads are used, particularly with non-uniform or stacked products.
