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.
Claims8
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.
