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.

Coexistent stacking system.

StackStar C.

The Stackstar C is our new coexistent and flexible robot for automatic stacking in print finishing. Designed for short and medium runs, Stackstar C reduces operator workload and ensures consistent performance. The robot integrates seamlessly with Stahlfolder folders and third-party systems for unmatched versatility.

Autonomous stacking of signature production.

StackStar P.

One operator moves up to seven tonnes of paper per shift. With the autonomous stacking system StackStar P, not only do you free your employees from labor-intensive tasks, you also achieve maximum productivity and cost-effectiveness because the physical workload is no longer a limiting factor.

Stahlfolder P-Stacker at a glance:

  • Robust, durable industrial robot
  • One gripper for all standard signature formats
  • Easy operation using graphical user interface and fully automatic setting of all makeready parameters
  • Automated insertion of intermediate layers by the robot
  • Turning of the signature packages by the robot (first page top to first page bottom)

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.
