A first identification tag 130 may be coupled to the outer circumference 105 of the round module 100. A second identification tag 135 may be coupled to the second end 115 of the round module 100. A third identification tag 140 may be coupled to the first end 110 of the round module 100. The first, second, and third identification tags 130, 135, 140 may be a first, a second, and a third electronic tags 145, 150, 155, respectively. Exemplarily, the electronic tags 145, 150, 155 may be a first, a second, and a third radio frequency identification “RFID” tags 160, 165, 170, respectively. The first, second, and third RFID tags 160, 165, 170 may be active tags that include an internal power source or passive tags that are energized by a field created by an RFID reader.
With reference to
The module-forming chamber 185 is similar to the module-forming chamber disclosed in commonly assigned U.S. Pat. No. 8,087,216, which is hereby incorporated by reference. A plurality of endless belts 190 define the circumference of the module-forming chamber 185. The plurality of endless belts 190 are supported in a side-by-side relationship across a support roll arrangement comprising a plurality of fixed rolls and a plurality of movable rolls. Specifically, proceeding clockwise from a chamber inlet 195 where crop enters the module-forming chamber 185, the fixed rolls include a lower drive roll 200, a first separation roll 205, a second separation roll 210, an upper drive roll 215, an upper front frame roll 220, an upper rear frame roll 225, an upper front gate roll 230, an upper rear gate roll 235, a lower rear gate roll 240, and a lower front gate roll 245 all coupled for rotation within the round module builder 80.
Referring to
The wrapping device 175 comprises a plurality of rubber wrap rolls 280 that guide the wrap 180. A belt 285 is positioned over a pulley 290 and driven by a rear power shaft 295. When driven, the belt 285 leads the wrap 180 along a wrap guide structure 300 and into the module-forming chamber 185, by way of the inlet 195, where the wrap 180 is positioned onto the round module 100 in the direction of the arrow 305.

In operation, the harvester 10 is driven through the field 35 to harvest cotton or other crop. The illustrated harvesting structure 55 doffs cotton from cotton plants in the field 35. Alternatively the harvesting structure 55 may strip the cotton from the cotton plants. Cotton is transferred to the accumulator 65 via the air duct system 60. The accumulator 65 holds the cotton until a predetermined cotton level is reached and then transfers the cotton to the feeder 70. In an exemplary embodiment, the accumulator 65 transfers cotton to the feeder 70 four times for each round module 100 produced. When the feeder 70 receives cotton, the plurality of rollers 75 are activated to compress the cotton. The compressed cotton is transferred to the round module builder 80.
After the round module builder 80 receives compressed cotton, the plurality of endless belts 190 rotate the cotton into the round module 100. After the round module builder 80 receives sufficient cotton from the feeder 70, the wrapping device 175 is initiated. The wrapping device 175 positions the wrap 180 onto the outer circumference 105, the first edge 120, and the second edge 125 of the round module 100. The wrap indication device 310 then measures an indication of the wrap 180 on at least one of the first edge 120 and the second edge 125 of the round module 100. Once the wrap indication device 310 has verified that the wrap 180 is on the round module 100, the second module-forming portion 90 is pivoted relative to the first module-forming portion 85, and the round module 100 can be ejected onto the module handling system 330. The module handling system 330 supports the round module 100 and then discharges it from the harvester 10.
A wrap indication device 710 comprises logic circuitry 735 configured to compare a first pressure reading 740 to a second pressure reading 745. Exemplarily, the first pressure reading 740 is of a pressure required to rotate a round module 500 using a lower drive roll 600 and an upper drive roll 615 taken before a wrap 580 is positioned. Exemplarily, the second pressure reading 745 is of a pressure required to rotate the round module 500 using the lower drive roll 600 and the upper drive roll 615 taken after a wrapping device 575 is initiated. The logic circuitry 735 compares the first and second pressure readings 740, 745 to determine if there has been a change in pressure, which indicates the wrap 580 has been positioned onto the round module 500.
The first and second pressure readings 740, 745 may be stored in memory 750. The first and second pressure readings 740, 745 may be transmitted to a display unit 755. If a wrap 580 is not positioned on the round module 500, a wrap alarm 760 may be initiated. The wrap alarm 760 may be audio, visual, or other types.
Various features are set forth in the following claims.
