End Of Travel Arrangement

摘要

An end of travel arrangement for shutting down an assembly line conveyor when an ergo assist arm at a conveyor station moves beyond an end of travel limit point, the end of travel arrangement including a trolley rail mounted alongside one of a pair of runway rails for supporting an ergo assist arm carriage with the trolley movable along the trolley rail. One or more proximity switches are mounted aligned with a home position on the trolley and detect when the trolley is displaced from the home position by contact of a feature on the carriage with the trolley and generate signals immediately initiating shutting down of the assembly line conveyor.

主权项

1. An end of travel arrangement associated with an assembly line conveyor and a station thereof including a carriage supporting an ergo assist arm used to perform an operation on a bolt advanced by said assembly line conveyor, said carriage movable along a pair of runway rails extending parallel to and alongside said assembly line conveyor, said end of travel arrangement including a trolley rail mounted alongside one of said runway rails with one end thereof located relative to said runway rail at an end of travel point beyond which said carriage is not designed to reach during normal operations;
an end of travel trolley mounted on said trolley rail to be able to be moved along said trolley rail and normally held located at a home position on said trolley rail; interengagable respective features on said carriage and said trolley coming into engagement by travel of said carriage past said end of travel point and displacing said trolley from said home position; one or more proximity switches mounted to a housing located at said end of travel point to detect the continued presence of said end of travel trolley at said home position, and when said trolley is displaced away from said home position, said one or more proximity switches generating corresponding electronic signals, said signals transmitted to an assembly line conveyor control causing shut down of said assembly line conveyor after said trolley is displaced from said home position.
