Quick change for transfer starwheel

A machine arrangement, comprising:

• a vacuum transfer turret assembly adapted to releasably hold one or more containers and to rotate the one or more containers about a rotation axis of the vacuum transfer the turret assembly when the one or more containers are held by the vacuum transfer the turret assembly, wherein the vacuum transfer turret assembly includes:
• a shaft assembly;
• a starwheel assembly, wherein the starwheel assembly is releasably secured to the shaft assembly;
• a vacuum manifold;
• a vacuum assembly;
• and
• a spacer, the spacer positioned between a starwheel mounting hub and the starwheel assembly, the spacer being configured to adjust the position of the starwheel assembly along the shaft assembly so the starwheel assembly can accommodate containers of different lengths,
• wherein rotation of the shaft assembly is configured to rotate the starwheel assembly relative to the vacuum assembly when the starwheel assembly is secured to the shaft assembly,
• wherein the starwheel assembly and the vacuum manifold are configured to move along the shaft assembly in a direction of the rotation axis of the vacuum transfer turret assembly towards and away from the vacuum assembly when the starwheel assembly is released from the shaft assembly and while the starwheel assembly is captured between the vacuum assembly and an outboard end of the vacuum transfer turret assembly, and
• wherein the starwheel assembly is configured to move to accommodate containers of different lengths.
