Automatic billet tagging system
Introduction
AlpRobTAG-S is a patented system designed to fully automate the billet tagging process using a highly effective and efficient pin welding method. The system provides a reliable method of product identification and traceability using heat- and wear-resistant synthetic labels applied by means of pins specially designed to withstand the harsh conditions of the steel industry.
Key features
Fully automated system based on a six-axis anthropomorphic robot
Laser profile sensors for extremely precise tool guidance
Precise tag positioning and robust sealing using a special pin
Wear-resistant and permanently printed tags
Customized identification and improved product traceability
Full compliance with operational safety standards
Improved efficiency and increased productivity
Reduced maintenance and continuous after-sales support
System architecture
The AlpTAG-S system is contained in a special housing depending on the operating conditions of the plant and in accordance with safety regulations. The robotic cell consists of a 6-axis anthropomorphic robot equipped with a customized automatic welding gun guided by a laser vision system. The patented pneumatic pin feeder ensures continuous feeding of welding pins and can be reloaded without interrupting the tagging cycle. Tag printing is accomplished by thermal transfer or laser technology. The system is redundant due to the presence of two printers that ensure continuity of service in case of maintenance on one of the units. The specially customized HMI operator panel, designed and developed by Alping engineers, completes the standard configuration. If necessary, the system can be further integrated with an auxiliary machine vision apparatus that scans the tag in real time to determine whether it has been applied correctly and the information printed without error.
How it works
The system first verifies the exact position of the billet, including detecting any obstacles, using a built-in sensor. It then processes the acquired data to determine the coordinates of the optimal spot on which to place the billet. The anthropomorphic robot picks up the tag from one of the thermal transfer (or laser) printing units, ensuring a secure grip. At the same time, the pin feeder ensures that the welding gun is properly loaded and ready for use. The robot then positions itself according to the coordinates provided by the system and proceeds to weld the tag onto the billet using the appropriate pin.
