Counting Jig for Packager

From ATWiki

Jump to: navigation, search



Some employees at a work activity center had the task of counting out exactly 49 nuts and placing them into a bag. The usual way to perform this task was to use a finger to slide each nut into a pile, one at a time. Some of the employees, particularly those with cognitive impairments, needed a structured way to count out the correct number of parts.

A device was created to help the workers complete the task without having to count pieces. This tray has exactly 49 machined recesses, which would trap one nut per recess.

A handful of nuts would be poured into the tray, the worker would then shake the tray until a nut was trapped in each hole. Once all of the indentations were full, the tray would be tilted slightly, and the excess nuts would fall out of a hole in the corner of the tray. What remains, are the exact number of components which can be immediately processed for packaging.
