Device for holding bobbin tube during waste removal includes spring-loaded spigot with ratchet that adjusts itself to appropriate tube length

摘要

A bobbin tube (3) is transported on a caddy (2) to a cleaning position where yarn residues (4) are removed as waste. The tube is held and centralized by a spring-loaded spigot (12) that is moved downward by an actuating cylinder (17) under the control of a sensor (31). The spigot is retained in its position by a ratchet arrangement (18). The spigot mounting includes a hollow tube fitted with a magnet that interacts with a Hall sensor (31) to control the actuator (17) movement.
