Abstract
A tie plate straightener includes a plurality of rollers having varying cross-section and differing elevations. The tie plate straightener includes directional wheels between the rollers and disposed in alignment with the lower elevations of the rollers. The straightener receives tie plates at an input and rotates the tie plates when the tie plate engages the directional wheels. The tie plate is thereby oriented and/or positioned so that the tie plate is supported above the directional wheels.
Claims19
A tie plate straightener, comprising:
- a roller conveyor having an input and an output and defining a longitudinal direction therebetween;
- a plurality of rollers at least some of which have a varying cross-section comprising ends having a larger diameter and a smaller diameter between said ends;
- at least one first directional wheel having an axis which is transverse to the plurality of rollers, said at least one first directional wheel disposed along the longitudinal direction between a first two of said plurality of rollers;
- at least one second directional wheel having an axis which is transverse to the plurality of rollers, said at least one second directional wheel disposed along the longitudinal direction between a second two of said plurality of rollers;
- said at least one first directional wheel turning in a first direction and said at least one second directional wheel turning in a second direction;
- wherein said first and second directional wheels are aligned in said longitudinal direction with a lower elevation of said varying cross-section of said plurality of rollers;
- wherein said first and second directional wheels have an upper elevation which is greater than a portion of said plurality of rollers.
