NEPATA Automatic Roll Storage System

Automation, Efficiency, and Control for your warehouse operations

In almost all converting processes, roll media is stored and retrieved. This can mean thousands of rolls and hundreds of picks per day in a typical warehouse. The traditional storage of rolls and their journey to the converting area (and back) incur significant costs and loss of time, while shelving racks consume valuable space and damage the surfaces of the rolls. Nepata has the solution: automated storage systems for roll media that revolutionize the pick-up and delivery process of media from the racking area to the converting are with increased efficiency, accuracy of picked order and reduction in damaged media.

Optimize storage of roll media with our innovative, tailor-made storage systems

The Nepata Automated Roll Storage System (ARSS) is designed for small to medium-sized warehouses requiring storage of up to 3,000 rolls of media. ARSS optimizes the picking and return process of rolls and the system frees up warehouse space by decreasing the footprint required to store rolls of media, reducing overhead and freeing valuable warehouse space for other uses.Each ARSS system is individually engineered to the customer's requirements in terms of dimensions (floor space, height), total capacity and number of transfer stations.

How the ARSS system works

The ARSS systems with a vertical robot are based on steel rack construction with horizontal mandrels where rolls of material are stored compactly. An automatic, vertical 3-axis robot removes the rolls for a specific job and when the job is complete returns the remainder rolls to their location on the racking. A specially designed gripper tray lifts the roll slightly from below and then lifts it down from the storage 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. Ideally, the NEPATA converting machines are placed directly next to the transfer stations at the rear of the storage system for an optimal workflow. The storage of remainder rolls is carried out accordingly. For safety reasons, the robot warehouse is completely fenced.

Automation of film logistics

ARSS can be fully integrated into the Nepata ConvertPlus2 (CP2) converting softwere. The production queues in CP2 are used to initiate the provisioning of film rolls at an early stage. In doing so, the control software optimizes the storage locations of frequently used films to reduce travel distances for the robot. The automatic storage system also notifies you when a new roll of a material is required and will load and store the new roll of media in the storage system. The ARSS software also gives preference rolls that are older or optimal in terms of remainder length avoid expired rolls and remainder rolls that are too short.
