Abstract
Abstract An automatic baling machine for forming round bales and wrapping them with twine is provided with a microprocessor-controlled signal processing circuit for controlling movement of a bidirectional motor which drives a pair of twine tubes. Retract/extend switches are manually actuated by an operator to store in the signal processing circuit a sequence of control words which are subsequently executed to control movement of the twine tube drive motor. In addition to being connected to the input of the signal processing system, the retract/extend switch are connected in parallel with the signal processing circuit to actuate the twine tube motor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
193 words
In an automatic baling machine having a plurality of manual input switches, a twine dispensing means, a drive motor for driving said twine dispensing means, means connecting said input switches to inputs of said signal processing circuit, said signal processing circuit being responsive to said input switches for selectively producing output signals to energize said motor, the improvement comprising: a signal processing circuit including a programmable microprocessor means responsive to a first and a second of said input switches for generating and storing a sequence of wrap control words, and subsequently producing output signals to energize said motor in accordance with said stored sequence of wrap control words; and, means connecting said first and second switches to said drive motor, said drive motor being energized from said signal processing circuit when said signal processing circuit is functioning properly and energized by selectively operating said switches when said signal processing circuit is not functioning properly, said switches being utilized to wrap a bale even though said signal processing circuit is not functioning properly, and also being utilized to control said signal processor to store control words for automatically controlling the wrapping of a bale.
Claim 2
Dependent Claim
193 words
In an automatic baling machine having a plurality of manual input switches, a twine dispensing means, a drive motor for driving said twine dispensing means, means connecting said input switches to inputs of said signal processing circuit, said signal processing circuit being responsive to said input switches for selectively producing output signals to energize said motor, the improvement comprising: a signal processing circuit including a programmable microprocessor means responsive to a first and a second of said input switches for generating and storing a sequence of wrap control words, and subsequently producing output signals to energize said motor in accordance with said stored sequence of wrap control words; and, means connecting said first and second switches to said drive motor, said drive motor being energized from said signal processing circuit when said signal processing circuit is functioning properly and energized by selectively operating said switches when said signal processing circuit is not functioning properly, said switches being utilized to wrap a bale even though said signal processing circuit is not functioning properly, and also being utilized to control said signal processor to store control words for automatically controlling the wrapping of a bale.
Claim 3
Dependent Claim
35 words
The improvement as claimed in claim 1 wherein said motor is a bidirectional motor and said automatic baling machine comprises first and second control means for selectively driving said motor in first and second directions.
Claim 4
Dependent Claim
19 words
The improvement as claimed in claim 2 wherein said twine dispensing means comprises first and second twine dispensing tubes.
Claim 5
Dependent Claim
64 words
The improvement as claimed in claim 3 wherein said first input switch is connected to said first control means and said second input switch is connected to said second control means whereby actuation of said first input switch causes said motor to be driven in one direction and actuation of said second input switch causes said motor to be driven in a second direction.
Claim 6
Dependent Claim
27 words
The improvement as claimed in claim 4 wherein said first and said second input switches are mechanically interlocked so that both of them cannot be actuated simultaneously.
Claim 7
Dependent Claim
58 words
The improvement as claimed in claim 4 wherein said first and second input switches comprise first and second sets of contacts, respectively, and means manually positioned to a first, second or third position to close only said first set of contacts, only said second set of contacts, or neither said first or said second set of contacts, respectively.
Claim 8
Dependent Claim
40 words
The improvement as claimed in claim 2 wherein said microprocessor means includes an input bus, said first and second input switches being connected to said input bus to apply a signal thereto any time either of said switches is actuated.
Claim 9
Dependent Claim
63 words
The improvement as claimed in claim 7 wherein said first input switch is connected to said first control means and said second input switch is connected to said second control means, actuation of said first input switch causing said motor to be driven in one direction and actuation of said second input switch causing said motor to be driven in a second direction.
