Work head changer for rotary vessel processing system

摘要

A work head changer is disclosed which automatically changes a capping head used in a rotary multicapper or a filling nozzle in a rotary filler. A controller controls the rotation of a rotatable body of the rotary multicapper, for example, thus bringing the individual capping heads to a stop successively and intermittently at a predetermined work head replacement position. In case of the rotary multicapper, each capping head is detachably mounted on the rotatable body through a connection. A work head delivery mechanism removes a capping head which is brought to a stop at the work head replacement position from the connection, and attaches a capping head of another variety which has been stored in a stocker to the connection at an empty location from which the capping head has been removed.
