Abstract
Apparatus for aligning large planar workpieces on a feed table wherein a plurality of pivoted arms are provided which are biased to a raised pivotal position to engage the edge of a workpiece, with the arms being urged to a lowered pivotal position by the weight of a workpiece resting thereon so that lateral movement of a plurality of the arms which may be arranged in rows will enable one of the arms of a row to engage the edge of a workpiece while in its raised pivotal position thereby to effect positioning or alignment of the workpiece.
Claims15
Apparatus for aligning planar workpieces on a feed table relative to a reference position comprising:
- means defining said reference position;
- base means;
- a plurality of arms each located a different distance from said reference position and each having a first and a second end;
- means pivotally mounting said first end of each of said arms to said base means;
- engagement means at said second end of each of said arms adapted to engage the edge of a workpiece to urge said workpiece against said means defining said reference position to effect a desired positioning thereof;
- biasing means applying a force urging said arms to a raised pivotal position at which said engagement means are located to engage an edge of said workpiece, said force of said biasing means being of a magnitude to enable each of said arms to be individually pivoted to a lowered pivotal position beneath a workpiece by the weight of at least one of said workpieces overlying said second end of said arm;
- and means for moving said arms laterally toward and away from said reference position to effect engagement of said engagement means against the edge of a workpiece depending upon the lateral dimension of said workpiece and upon the position of the arm upon which said engagement means is mounted relative to said reference position.
