Abstract
A wire feeding apparatus is disclosed. The wire feeding apparatus includes a rotable drive shaft, a servo motor in driving relationship with the drive shaft and one or more feed modules. Each feed module is selectively engaged with the drive shaft through the use of a linear actuator. When the linear actuator is engaged, each feed module is driven by the drive shaft such that wire is either fed or retracted.
Claims22
An individually selectable feed module for a bulk material baler, said feed module comprising:
- a base plate;
- a first spindle mounted on said base plate;
- an eccentric attached to said first spindle;
- a first drive wheel, said first drive wheel having a first gear, said first drive wheel and said first gear being mounted in operative communication with said eccentric such that an axis of rotation of said first drive wheel is pivotally and arcuately movable between a removed position and an engaged position;
- a second spindle mounted on said base plate;
- a second drive wheel rotationally mounted on said second spindle, said second drive wheel also having a second gear, said second gear being adapted to receive a rotational drive;
- said engaged position disposing said first drive wheel and said second drive wheel in sufficient proximity to frictionally drive a wire therebetween;
- and
- an actuator, said actuator being operatively engaged with said eccentric such that activation of the actuator pivots the first drive wheel along an arcuate path between said engaged position and said removed position.
A wire feeding apparatus comprising:
- a rotatable drive shaft;
- a servo motor in a driving relationship with said rotatable drive shaft, said servo motor adapted to rotate said rotatable drive shaft in a first direction and in a second direction;
- a plurality of feed modules, each of said plurality of feed modules comprising:
- a. a fixed gear in a driven relationship with said drive shaft;
- b. a first feed wheel connected to said fixed gear;
- c. a pivotable gear mounted such that an axis of rotation of said pivoting gear is pivotally movable along an arcuate path toward and away from said fixed gear;
- d. a second feed wheel connected to said pivotable gear;
- e. a pivot arm operatively connected to said pivotable gear;
- and
- a plurality of linear actuators, each of said plurality of linear actuators connected to each of said pivot arms of said plurality of feed modules such that movement by one of said plurality of linear actuators pivots a corresponding pivot arm from a disengaged position to an engaged position such that a corresponding said first feed wheel and corresponding said second feed wheel are in sufficient proximity to drive a wire therebetween.
A method of controlling a wire feeding apparatus, the method comprising the steps of:
- a. providing a fixed gear connected to a first feed wheel and a pivotable gear connected to a second feed wheel, said pivotable gear mounted such that an axis of rotation of said pivotable gear is pivotally movable along an arcuate path toward and away from said fixed gear;
- b. providing a pivot arm connected to said pivotable gear and a linear actuator connected to said pivot arm;
- c. engaging said linear actuator;
- d. pivotally moving said pivotable gear along an arcuate path toward said fixed gear;
- e. frictionally engaging a wire with said first feed wheel and said second feed wheel;
- f. engaging a servo motor;
- and
- g. rotating a drive shaft connected to said fixed gear.
