Abstract

In the manufacture of small, e.g., .5 inch x .5 inch x .05 inch printed circuit ceramic modules, problems arise in transferring the modules from one conveyor system to another. Where a gate type mechanism is used to align the modules before they are transferred from the one conveyor belt to the other, the modules often are trapped underneath the gate. This causes a jamming of the mechanisms, jerking of the conveyor system, and misalignment of the ceramic modules on the entire conveyor belt.

Conveyor Unloader

In the manufacture of small, e.g., .5 inch x .5 inch x .05 inch printed circuit ceramic modules, problems arise in transferring the modules from one conveyor system to another. Where a gate type mechanism is used to align the modules before they are transferred from the one conveyor belt to the other, the modules often are trapped underneath the gate. This causes a jamming of the mechanisms, jerking of the conveyor system, and misalignment of the ceramic modules on the entire conveyor belt.

This unloader transfers ceramic modules from one conveyor belt to the other without necessitating an alignment gate. Modules are transferred from conveyor belt 1 to conveyor belt 3 by vacuum pickup 5. The vacuum is supplied through hose 7 to a plurality of small holes in the lower surface of pickup 5. The motion of the latter is controlled through reciprocating arm 9 and roller 11 riding against cam surface 13. So that there is no sudden change in the movement of pickup 5 so as to jolt any modules loose, cam surface 13 is curved between its vertical and horizontal portions. Modules traveling on the moving belt are sensed by photoelectric sensor 15. This contains two spaced photoelectric cells to insure that no errors occur due to lateral spacing between modules in a single row.

Normally, pickup 5 is located slightly above belt 1. When sensor 15 senses a row of modules, reciprocating arm 9 is moved slightly rightward and the vacuum supplied through hose 7 is a...
