Automated RFID Tagging for Round Bales
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for tagging round bales of organic material are inefficient and prone to human error, particularly when conducted outdoors in adverse conditions, and require specialized equipment for RFID reading, which is not always readily available.
Innovation Solution
A fully automated device that positions RFID tags at the center of round bales during wrapping, using NFC technology for easy reading with smartphones and protecting tags with multiple layers of plastic, allowing for efficient and error-free tagging without integrating with the wrapper, making it suitable for existing machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tagging is performed outdoors in adverse conditions, then tagging can be done at the site of packing, but efficiency is reduced and human error increases
Solution Approach 1:
The system uses NFC technology where smartphones automatically read RFID tags when brought near the bale, eliminating the need for specialized reading equipment and manual data entry. The tagging device feeds tags automatically to the applicator, reducing manual intervention and errors in adverse outdoor conditions.
Solution Approach 2:
The patent replaces manual mechanical tagging operations with an automated device that positions and applies RFID tags. The system substitutes human labor with mechanical automation for tag feeding, positioning, and application, significantly improving efficiency while maintaining outdoor operational capability.
2Ease of manufacture
If RFID tags are applied without protection, then tagging is simpler, but tags are vulnerable to environmental factors
Solution Approach 1:
The patent wraps the applied RFID tag with plastic wrapping film as part of the bale wrapping process. This flexible film protection shields the tag from environmental factors such as moisture, UV radiation, and physical damage, ensuring tag durability and reliable reading throughout the bale's storage and transport lifecycle.
3Measurement precision
If specialized RFID reading equipment is required, then reading accuracy is maintained, but equipment availability is reduced
Solution Approach 1:
The patent implements NFC compatibility that allows standard smartphones to read RFID tags without requiring specialized equipment. The system maintains reading accuracy by using standardized NFC protocols while achieving universal accessibility through devices everyone already carries, eliminating the need for dedicated RFID readers.
4Extent of automation
If tagging is integrated with the wrapper, then automation is improved, but device complexity increases
Solution Approach 1:
The patent designs the tagging device as a separate, independent unit that operates parallel to the wrapper rather than integrating it into the wrapper system. The tagging device includes its own tag magazine, applicator mechanism, and control system, allowing automated tagging without increasing wrapper complexity. Both systems operate independently but coordinate through timing signals.

AI summary
Method and device for tagging round bales (61) during wrapping in plastic foil, using a stationary or mobile baler-wrapper. Each round bale is oriented with the circular end surfaces mainly vertically and layers of plastic foil is wrapped around the round bale by foil wrapping arms (63). At a point in time where at least one layer of plastic film remains to be wrapped, each round bale is tagged with an ID tag (25) having an adhesive back-side surface, using a time controlled, pivotal tagging arm (22) provided with a tag transferring member (23). The movement of said tagging arm (22) is controlled by a computer, which synchronizes the movement of the tagging arm with the movement of the foil supplying arms. After tagging, at least one additional layer of plastic is wrapped around each round bale to protect the ID tag (25).
