Sawmill code marking and reading system RFID

RFID technology was used in the Indisputable Key for individual identification of logs in the forest and in the saw mill. A novel pulping compatible passive UHF RFID transponder was developed for marking logs automatically by the harvester or using a manual tool. The transponder is EPC Class 1 Generation 2 compatible so it can be read with all compatible readers.

The reading of the transponders inside wood is demonstrated together with association of data with the ID, i.e. the log.

Log code marking and reading

A log code printer has been designed and developed in the Indisputable Key project to enable printed code marks on log end surfaces by a harvester machine. The applicator has a modular designed and is mounted on the harvester aggregate. A 2 dimensional code is applied during the cutting procedure with ink as the marking substance.

The applicator facilitates code types such as data matrix code with up to 1 million identities. Custom made barcodes is also possible to apply. The marking concept major advantages are the low marking cost(below €0,002) and the fact that there is no production time loss. Concurrent with the development of the marking device a detection equipment was developed. The detection is based on vision technology i.e. software processed digital images. The equipment is designed for installation at a sawmill.

Proof of concept was performed by field tests of the marking and reading equipment.

Sawmill code marking and reading system

Tallinn University of Technology is responsible for coordinating Indisputable Key project workpackage 5 – alternative code marking and reading of logs boards and packages.
Our main tasks are developing sawmill code marking and reading system, handheld marking device and log code reading system in SK Rolpin, France.
During the final seminar we will demonstrate:
•Board marking with datamatrix code
•Fluorescent light excited and normal visual code marking-reading
•Local Swedish Wood Supply Chain synchronization adapter for Serta Mala sawmill
•Setra Mala code reading system monitoring interface
•SK Rolpin log code reading software

Traceability Services and ICT solutions

ICT solutions used for data collection in Indisputable Key and Traceability Services by Tieto will be demonstrated. Traceability Services offers a unique combination of sustainability and supply chain performance management based on globally agreed standards. The environmental reporting follows the guidelines of LCA methodology. In addition LCA reporting, Custom reports can be easily created based on environmental and traceability data The solution is offered as Software as a Service, offering low start-up costs, secure handling of data, short deployment time, global availability via internet.
We will show how data was collected from the supply chain and how KPIs are visualized for industrial users. We will also show how ICT could help you manage supply chain in a more effective way.

Wood Supply Chain Simulation Model

IVL Swedish Environmental Research Institute will demonstrate the Wood Supply Chain simulation model that was developed in Indisputable Key. The model is accessible on the web and calculates Key Performance Indicators (KPI) for environmental impact, costs and quality aspects for the wood supply chain, from harvesting in the forest to pieces of wood components at the secondary manufacturer.
We will show how a user can select its own model settings on tree properties, transportation, sorting procedures, prices and time. It will also be shown how to study the subsequent effect of those settings on the KPIs of the resulting product, the different steps in production and the whole wood supply chain
