Abstract

This article describes a multi-position "Z" stop which satisfies the need for adjustable incremental control of a manufacturing system "Z" axis arm. The multi-position "Z" stop concept disclosed herein is illustrated in Fig. 1 in assembly form. Fig. 2 is a schematic wiring diagram showing the operation of the manufacturing system. Referring to Fig. 1, the stops 1 are solid-state optical switches which operate by sensing a stop flag 2 mounted to shaft 3 of air cylinder 4 which powers the "Z" arm of the manufacturing system. Only three variable stops are shown. However, more stops can easily be added, as needed. Each stop is mounted on a support bracket 5 which is fixed to casting 6. The stops 1 are adjustable to any position on the bracket 5.

Multi-Position "Z" Stop

This article describes a multi-position "Z" stop which satisfies the need for adjustable incremental control of a manufacturing system "Z" axis arm. The multi- position "Z" stop concept disclosed herein is illustrated in Fig. 1 in assembly form. Fig. 2 is a schematic wiring diagram showing the operation of the manufacturing system. Referring to Fig. 1, the stops 1 are solid-state optical switches which operate by sensing a stop flag 2 mounted to shaft 3 of air cylinder 4 which powers the "Z" arm of the manufacturing system. Only three variable stops are shown. However, more stops can easily be added, as needed. Each stop is mounted on a support bracket 5 which is fixed to casting 6. The stops 1 are adjustable to any position on the bracket 5. This adjustment is accomplished by loosening a clamp screw of the stop to be moved, sliding the stop up or down along the bracket to the desired location, and then retightening the clamp screw. The stops 1 provide the necessary sensing for positional control of the "Z" arm 7 which is connected to shaft 3 by support arm 8. Each of these stops 1 is assigned to one of sixteen available digital inputs which are standard to the manufacturing system controller. Once each of the stops 1 is tied into the digital input of the controller, then each time one of the stop switches is tripped, the controller knows where the "Z" arm is located. Using standard software, this information is used to activate one of six...
