Bale identification assembly for binding an identification tag to a bale of agricultural crop material
A bale identification assembly has a binding material with identification tags at spaced intervals is used by a knotter system to bind a formed bale. A read module with an antenna transmits interrogator signals and also receives authentication replies from identification tags. The bale identification assembly has a bale drop sensor with a paddle. As a completed bale passes through the discharge chute, the completed bale interacts with the paddle causing the bale drop sensor to activate. Activation of the bale drop sensor activates the antenna for a specified active cycle, and during its active cycle, the read module assigns any identification tag that is sensed to the completed bale that is leaving the discharge chute. A controller receives information from at least one crop sensor and/or bale sensor and associates the information about the completed bale with the identification tag on the completed bale.
1. A bale identification assembly for use with an agricultural baler used to take loose crop material from the ground into bales and compress a formed bale in a baling chamber with a reciprocating plunger, the baler having at least one crop sensor and/or bale sensor configured to sense a parameter of the crop material or formed bale, a knotter system that uses a binding material to bind the formed bale and tie a knot in the binding material, and a discharge chute at the rear end of the bale-forming chamber through which a completed bale is discharged, the bale identification assembly comprising:
a binding material used by the knotter system to bind the formed bale, the binding material comprising identification tags at spaced intervals along the binding material, wherein the knotter system comprises a first supply roll of binding material having identification tags and a second supply roll with binding material without identification tags, wherein the knotter system combines binding material from the first supply roll with binding material from the second supply roll to bind the formed bale;
a read module with an antenna configured to transmit interrogator signals and also receives authentication replies from identification tags;
a bale drop sensor comprising a bale activation device, wherein as a completed bale passes through the discharge chute, the completed bale interacts with the bale activation device causing the bale drop sensor to activate, wherein activation of the bale drop sensor activates the antenna for a specified active cycle, and wherein during its active cycle, the read module assigns any identification tag that is sensed to the completed bale that is leaving the discharge chute; and
a controller configured to receive information from the at least one crop sensor and/or bale sensor and associate the information about the completed bale with the identification tag on the completed bale that is leaving the discharge chute.
2. The bale identification assembly of claim 1 wherein the binding material having identification tags comprises at least one strand of a non-identifying filament and one strand of an identifying filament incorporating the identification tag, wherein the non-identifying filament and the identifying filament are wound together before the binding material is used to bind the bale of crop material.
3. The bale identification assembly of claim 2 wherein the identifying filament comprises an radio-frequency identification (RFID) inlay, wherein the RFID inlay comprises conducting wires of an antenna connected to an RFID chip, and the RFID inlay comprises a segment of the identifying filament with adjacent RFID inlays spaced along the identifying filament at a desired interval, and the identifying strand incorporating the RFID inlay is wound during a binding material production process with at least one non-identifying filament into a single twine strand.
4. The bale identification assembly of claim 1 wherein the bale activation device is a paddle.
