Substrate Size Sorter

This apparatus automatically separates oversize substrates from substrates which are of the proper size and undersized.

Apparatus 10 has a downwardly inclined slide 12 for supporting substrates 14 to be sorted. In A, substrates 14 are sliding down slide 12 beneath sizing rollers 16 and 18. The relationship of slide 12, substrate 14 and roller 16 is shown in B. Roller 16, rotating in the direction of arrow 17 about an axis that is angled relative to the longitudinal axis of slide 12, is located to frictionally engage and flip oversize substrates off slide 12.

However, substrates, which are of the desired width and undersized, pass beneath roller 16 and proceed down slide 12. Roller 16, preferably of rubber or other suitable semiresilient material, is mounted on bracket 20 which is slidably mounted on slide 21. The position of bracket 20 can be adjusted with screw mechanism 22. Rollers 16 and 18 are driven by motor 24. Roller 18 is mounted on an assembly similar to the mounting assembly of roller 16.

In operation, substrates 14 are moved down slide 12 beneath roller 16. Here they are either ejected from the slide or allowed to proceed if below the size tolerance. Peg 26 imports a quarter turn to the substrates that have passed beneath roller 16. The substrates are then checked for tolerance in the traverse dimension by roller 18.

The slide 12 can be extended, either above or below rollers 16 and 18, and roller 30, as shown in C, can be used to...
