DETAILED DESCRIPTION

[0019] Referring now to FIGS. 1-2, an automatic de-wiring machine 50 is shown comprising a conveyor 60, a profiling arm 1, a cutter (shown in later figures) and a wire winding apparatus 30. A bale 4 enters the automatic de-wiring machine 50 and is moved to the profile arm 1 with conveyor 60. The profile arm 1 reads and records the topography, or contour, of the bale 4, such that the winding apparatus 30 can be positioned appropriately throughout the bale 4 without missing wires or jamming into the bale.

[0020] Referring now to FIGS. 3-10, the profile arm 1 has a frame 15, a positioning arm 5, a profiling wheel 2, a sensor arm 3, a proximity sensor 20, a linear transducer 8, a profile shaft 9, a track 19, a linear transducer mount 10, a linear transducer carriage 18, and a pivot shaft 6. The sensor arm 2 provides for an up/on and down/off position. When the sensor arm 2 is in the up/on the proximity sensor 20 registers the change and relays to the linear transducer 8 which begins recording the topography of the bale. When the sensor arm 2 is in the down/off the proximity sensor 20 registers the change and relays to the linear transducer 8 which stops recording the topography of the bale.

[0021] Profile wheel is moveably connected to position arm 5 and profile shaft 9. Position arm 5 is movably connected to frame 15 via shaft 6. Frame 15 also contains track 19 that allows linear transducer mount 10 to move along frame 15 as position arm 5 is raised and lowered. Also connected to linear transducer mount 10 is a holder for profile shaft 9 which moves in conjunction with linear transducer mount 10. Attached to linear transducer mount is linear transducer 8. A linear transducer carriage 8 is movably connected to linear transducer 8. The profile shaft 9 is in communication with linear transducer carriage 13. Such that as the profile wheel 2 moves up and down to follow the topography of a bale, so does profile shaft 9. Profile shaft 9 is in communication with the linear transducer carriage 13, which moves up and down linear transducer 8. The linear transducer 8 records said movement of the linear transducer carriage 13 and therefore the movement of the profile wheel 2. The sensor arm 3 is in communication with a proximity sensor 20, the proximity sensor monitors the position of the sensor arm 3 and then relays to the linear transducer 8 when to stop and start recoding movement. In FIG. 11 the proximity sensor 20 is located near the sensor arm 3, this is the preferred embodiment.

[0022] Position arm 5 is pulled down by gravity such that the profile wheel 2 is in constant contact with the bale 4. Gas shock 7 prevents position arm 5 from crashing down once a bale has left.

[0023] When bale 4 reaches profile arm 1, via conveyor 60, the profile arm engages the bale using the profile wheel 2 and sensor arm 3. Once engaged, sensor arm 3 is moved into the up position, the proximity sensor 20 detects the change in position of the sensor arm 3, and relays to begin recording. Profile wheel 2 follows the topography of bale 4 moving up and down as the topography or contour changes. The profile shaft 9 mimics the movement of the profile wheel which is relayed to the linear transducer 8 via the linear transducer carriage 13. The linear transducer 8 records the movements of the linear transducer carriage 13 until sensor arm 3 is disengaged.

[0024] The linear transducer 8 now has a profile of the contour of a bale and relays that to a PLC (not shown). The conveyor 60 is also in communication with the PLC. The PLC is programmed to calculate the distance of the bale based on data of the distance traveled by conveyor 60, along with the topography of the bale based on data from linear transducer 8. The PLC then relays this date to the de-wirer 30. The de-wirer has a blade 40 that cuts the wire from around the bale 4. A winding head 31 spins to collect the cut wire. The winding head 31 is moved up and down to follow the contour of the bale and remove the wire. The winding head 31 is disengaged when the PLC indicates that the end of the bale has been reached.
