Level up automation
Automated identification of mother reels with RFID pushes intralogistics in tissue industry to a new level.
"People-free intralogistics process requires a reliable and automated identification of the mother reels from any direction"
The Customer Challenge
On its site in Mainz WEPA decided to automate the intralogistics process of mother reels with automated guided vehicles (AGV) from Elettric80 Spa, which are managing a floor warehouse. Mother reels produced by the paper machine are transported and stored into the warehouse by AGV. The converting process where mother reels are processed into to end products is as well supplied with mother reels by AGVs. Since there are no persons involved in the intralogistics process the reliable and automated identification of the mother reels is crucial. Reels must be identifiable reliably from any direction by the AGV system and the converting machines for logistics automation and production traceability.
The Turck Vilant Systems Solution
The identification process is based on Vilant Systems RFID readers and software combined with Sonoco Alcore’s Intellicore UHF RFID equipped paper cores. When the paper is produced on the core, the reel identification number and parameters are programmed into the RFID transponder of the tissue reel core by the paper machine. The AGV process and conversion machines can then automatically identify the reel with RFID readers, which identify the reel ID though the paper in the process points.
In tissue manufacturing the cores are reused after the paper has been consumed by the converting machines. The RFID tag integrated into the core is a cost efficient identification solution since it can be reused as long as the core is functional for reuse.
The RFID readpoints are controlled with Vilant Engine software, and the entire process managed by Vilant Visibility Manager Server (VVM). VVM is also used for integration of RFID process information into back end systems like the AGV WMS and ERP.
- Reusable integrated Sonoco Alcore’s Intellicore RFID cores are a cost efficient means of reel identification
- Automated traceability enabled on the converting machines, which now can identify the reels automatically and connect reel numbers to production lots
- Vilant RFID middleware, which enables a real time process visibility and integration for all paper reel movements in the intralogistics process.
