Conveyor for bottle-filling machine

摘要

A conveyor chain has lower pins and is displaced in steps through a station. Respective pairs of plates have holes fitted to the pins and confronting cutouts together forming seats shaped to fit complementarily around necks of bottles. Horizontally displaceable supports in the station above the chain carry downwardly projecting upper pins. An actuator raises the plates in the station and thereby slides the holes of the plates in the station from the lower pins onto the upper pins. The arms and upper pins are moved apart when the plates are on the upper pins to open up the seat so that a bottle can be fitted to or taken out of the seat. The arms and upper pins are moved together when the plates are on the upper pins to close the cutouts around a bottle positioned between them, and then lowered back down onto the lower pins.
