Automatic roll storage system with vertical robot

Automation, efficiency and control for your warehouse processes

In almost all converting processes, roll media must be stored and retrieved. This can mean thousands of rolls and hundreds of picks per day in a value chain.

The traditional storage of rolls and the way to the converting area (and back) cause significant costs and time losses. Despite high-speed sortation, inefficient pick-up and drop-off times persist, while shelving eats up valuable space and damages roll surfaces. Nepata has the solution: Innovative automatic storage systems for roll media that revolutionize the pick-up and delivery process and increase your efficiency.

Optimize the storage of your roll media with our innovative, customized storage systems

The Nepata Automated Roll Storage System (ARSS) is designed for small to medium roll storage with a total capacity of up to 3,000 rolls. In addition to the software-based optimization of processes, the system is characterized above all by the small footprint required for storing the rolls. In each case, the system is individually adapted to the customer’s requirements in terms of dimensions (footprint, height), total capacity and number of transfer stations.


The roller storage system with vertical robot is based on a steel rack structure with horizontal mandrels on which the rollers hang very compactly. An automatic, vertical 3-axis robot sequentially moves to the rolls required for each job. Its specially designed tray gripper lifts the roll slightly from below, then lifts it down from the mandrel. The gripper then places the roll in a free transfer station. As soon as a roll is ready, the machine operator can manually open the transfer station like a drawer and remove the roll. The machines are ideally placed directly next to the transfer stations at the back of the storage system for optimal workflow. The storage of used rolls is done accordingly. For safety reasons, the robot warehouse is completely fenced in.


The supplied software of the robotic storage system can be fully integrated into the well-known Nepata control software ConvertPlus. The provision of film rolls is triggered at an early stage via the production queues. The control software optimizes the storage locations of frequently used films in order to reduce travel distances. The automatic storage system also signals when a new roll of a material is needed. This can then also be set at a transfer station. On the software side, it is also controlled that those rolls are preferably used which are already older or optimal with regard to the remaining length, in order to avoid overaged rolls and too short remainders.

“Automation to counteract shortage of skilled workers and overwork!

Many companies in the industry face the difficulty of not finding suitable personnel for logistics tasks or using existing capacities in a more value-adding way. The sickness rate due to the physically demanding work and the fluctuation due to the high workload also pose major challenges for companies. With an ARSS, personnel capacities can be saved and burdensome work can be minimized. Invest spare capacity in new growth potential for your business!”
