Over the last 4 years, Heidelberg has perfected autonomous print production through its Push to Stop technology on Speedmaster presses. Greater efficiency in print production, however, can also result in some hiccups downstream in finishing. At the delivery of a high-performance folder, the operator stacks around seven tons of paper on the pallet each shift. Each pile weighs almost eighteen pounds and arrives at a rate of up to five per minute. The stress on the operator usually means the folder must be slowed down, interrupted, or even stopped, so the operator can take a break. This often means that even if you have a high-performance folder, you aren’t maximizing its full potential. With pallets of paper lining up for finishing, Heidelberg has been working to bring an autonomous approach to folding.

Enter – the Stahlfolder P-Stacker, a robust, six-axis industrial robot that gently and securely grips and autonomously places each signature pile onto a pallet using sophisticated gripper technology. The P-Stacker has been optimized to ensure zero marking as the signature piles are gripped and transferred to the pallet at a speed of up to 300 stacks per hour (stacks can range from 5.70” x 5.70” to 13” x 13”). Additionally, it can be programmed with a variety of pallet set down configurations, and every stack is jogged prior to palletization.

With a simple, intuitive interface, the Stahlfolder P-Stacker ensures high productivity and efficiency in the folding process, reduces the operator’s workload, and allows the operator to focus on other tasks like quality control. The future is here for autonomous folding production.
