Industrial & Manufacturing

A gripper end-effector adapted to KUKA robotic manipulators for removing pressed product from a semi-dry pressing machine and arranging it in stacking patterns per a preset program. Handles 1 to 9 products per cycle at 15 kg total load capacity.

  • Engaged — multi-product cycle on KUKA manipulator.
  • Mid-cycle — KUKA tool flange interface, 15 kg total load.

The Challenge

KUKA manipulators are widely used in industrial automation — but a manipulator without the right end-effector is a robot waiting for a job. For cladding-product lines, the end-effector has to handle 1 to 9 products per cycle (the press's output count varies by product geometry), survive cement-binder dust, and integrate cleanly with the KUKA's tool flange without forcing custom robot-side modifications.

What "adapted to KUKA" actually means

  • *Mounting interface.* The gripper mounts on the KUKA tool flange — no robot-side modification needed.
  • *Communications profile.* End-effector control follows KUKA's expected interface so the cell controller doesn't need bespoke wiring.
  • *Payload within rated envelope.* 15 kg total — sized to the robots typically deployed on this kind of cell.

Why product count per cycle varies

The press output count depends on geometry and tooling. A standard brick press might output 5 per cycle; a smaller-product press might output 9. The end-effector has to handle the full range from 1 product to 9 products per cycle without geometry-specific re-tooling between runs.

Our Approach

We designed the end-effector against the KUKA mounting and communication profile, with a gripping geometry that accommodates 1 to 9 products per cycle at a constant total load capacity of 15 kg.

Engineering inputs

  • *KUKA tool flange interface.* Standard mounting — no robot-side custom work.
  • *Gripper geometry.* Accommodates the press's output count range (1 to 9 products) without re-tooling for product changes.
  • *Cycle behavior.* Pick-place-release cycle matched to the KUKA's typical motion envelope.
  • *Stacking-program follower.* Stacking patterns set by preset program at the cell controller — the gripper executes; the controller decides.

Why standardize the mount

A captive end-effector locks the cell into a specific gripper. A KUKA-standard mount means the same robot can be re-tooled to other end-effectors when needed (maintenance, product change, repurposing) without engineering work on the robot itself.

Results

The end-effector is in service on KUKA manipulators handling cladding output at the press exit. 1 to 9 products per cycle, 15 kg total load, mounted on the KUKA tool flange without robot-side modification.

Operational behavior

  • *Variable cycle output.* Same end-effector handles single-product and multi-product output without re-tooling.
  • *Stacking-program flexibility.* Pattern is set by the cell controller; the end-effector follows.
  • *KUKA-portable.* The same gripper design can move between KUKA robots in a multi-cell facility.

Why the variable product count matters

Most grippers handle a fixed product count per cycle. That's fine when the press's output is fixed. The moment the line introduces a product variant with a different press-output count, a fixed-count gripper has to be re-engineered or replaced.

Designing for the 1-to-9 range up front means the line can introduce new product geometries — within that count range — without going back to the gripper designer. That's the difference between a gripper tied to one product and a gripper tied to the customer's *line*.
