Abstract

This article describes a high density high volume, low cost, unit handling/test system. This system can be used for applications for computer CPUs, display terminals and similar types of equipment. Equipment currently available and in use for these applications typically utilizes either Automatic Storage/Retrieval Systems (AS/RS) totestackers or carousels. The throughput capacity of these systems is governed by the stacker unit or the carousel loader/unloader unit and by the unit storage capacity. It should be noted that when these units are down for service, the entire line is down. The system disclosed herein utilizes zero pressure, accumulating powered conveyors 1, as shown in the side view of Fig. 1, for the unit storage/test medium.

Programmable Unit Handling/Test Module

This article describes a high density high volume, low cost, unit handling/test system. This system can be used for applications for computer CPUs, display terminals and similar types of equipment. Equipment currently available and in use for these applications typically utilizes either Automatic Storage/Retrieval Systems (AS/RS) totestackers or carousels. The throughput capacity of these systems is governed by the stacker unit or the carousel loader/unloader unit and by the unit storage capacity. It should be noted that when these units are down for service, the entire line is down. The system disclosed herein utilizes zero pressure, accumulating powered conveyors 1, as shown in the side view of Fig. 1, for the unit storage/test medium. The horizontal sections of the conveyors 1 are constructed "X" level long, "Y" level high, and two rows wide, as shown in the end view (Fig. 2), with "X" and "Y" determined by the application throughput required. The two parallel rows of stacked conveyors 1 are loaded by a single vertical lift 2 at one end, as shown in Fig. 2, and unloaded by a single vertical lift 3, as shown in the top view of Fig. 3, at the opposite end forming the handling module 7. The vertical lifts are programmable such that either or both rows on a given level can be accessed or serviced by the lift. The system input is provided by powered roller conveyor 4. Output is provided by powered roller conveyor 5. Additional...
