Abstract
A conveyor for separating and aligning glass sheets moving along a sheet movement path includes a plurality of cylindrical rolls skewed relative to the movement path to displace the advancing sheets toward a side of the conveyor. At the side of the conveyor the sheets are aligned by an endless belt rotating through a path parallel to the sheet movement path. Each successive roll in the direction of sheet advancement has increasing peripheral surface rotational speed to separate the advancing sheets.
Claims3
A conveying system for separating and aligning sheets as they move along a sheet movement path, comprising:
- a superstructure;
- a plurality of cylindrical conveying members having successive increasing diameter in the direction of sheet advance to insure increasing spaced distance between edges of adjacent sheets as the sheets advance along the sheet movement path;
- means for rotatably mounting said conveying members in spaced relation to one another on said superstructure with their axial centers parallel to one another and at an oblique angle to the sheet movement path, said rotatably mounting means including means for changing the oblique angle;
- means for rotating said plurality of conveying members at the same axial rotational speed;
- endless belt;
- means for mounting said endless belt adjacent a side of said superstructure with major surface of said belt normal and parallel to the sheet movement path;
- and
- means for rotating said endless belt.
