Autonomous stacking
of signature packages.

Stahlfolder P-Stacker.

Did you know that the operator of a folding machine in the industrial sector moves a weight of 7 tons every shift, which is about the equivalent to a large, fully grown elephant ? Reduce your operator’s workload now, and in doing so exploit the full potential of your highly productive folding machine.

With the brand-new Stahlfolder P-Stacker, you can now avail of
state-of-the-art robot technology in your postpress.

This, combined with the innovative gripper technology and the sophisticated feed line, results in a harmonious overall solution for taking signature packages from the delivery and stacking them on the pallet fully autonomously. This is a very easy way of further increasing the folding machine’s utilization, while at the same time reducing the operator’s workload. You won’t need to worry about the quality of the piles on the pallet anymore, either.

The Stahlfolder P-Stacker stacks up to 300 packages per hour – fast enough to keep up with even the most productive folding machine. It can produce a pile height measuring up to 1.06 m on EPAL 1 Euro pallets.

Key features

Feed table
The feed table separates the packages during production in two-up mode and acts as a buffer section during the pallet change

Aligning and jogging station
The aligning and jogging station serves as the transfer point for the signature packages to the robot. Two vibrating plates attached to the side ensure flush piles before transfer.

Touchscreen control
The Stahlfolder P-Stacker is controlled via an intuitive graphical user interface. Most common formats and stacking layouts can be set fully automatically and in next to no time by entering a few parameters. We can program special stacking layouts for you on request.

Industrial robot
The robot from Fanuc integrates seamlessly into the overall system and boasts impressive robustness and durability. Its performance is also perfectly matched to our requirements for such a system.

Gripper
The gripper of our Stahlfolder P-Stacker grips formats between A5 and A4. The formats can be set flexibly and automatically. It grips extremely reliably, yet gently enough so as not to damage any sheets. It places the packages close together in rows on the pallet.
Its features include two suction heads for automatically inserting intermediate layers.

Safety concept
In the long run, only a robust industrial robot can deliver real performance paired with maximum technical availability. But a robot like this needs a safety fence. That is why we deliberately chose this robot with a compact lattice fence. This enables you and your operator to work safely and as intended on the Stahlfolder P-Stacker, which has been tested by an external, neutral test center and certified with the GS mark.
