A recently filed patent (Publication Number: US20230183051A1) describes a container-handling apparatus that is designed for use in a filling machine. The apparatus includes a first transporter that serves as a container infeed, a rotor positioned downstream of the first transporter, and a second transporter that functions as a container outfeed. The rotor has multiple handling positions for the containers, and the second transporter consists of a chain conveyor with guide fingers that move along a curved first transport path and a straight second transport path. The guide fingers are responsible for guiding the containers along the transport path, ensuring firm contact with a guide rail.

The container-handling apparatus is specifically configured for use in a filling machine for liquid products. It is designed to fill containers with a liquid filling product and transport them in a specific handling direction. The second transporter, which includes the chain conveyor and guide fingers, is responsible for guiding the containers along the transport path.

The second transporter, within the curved first transport path, consists of an upper guide rail and a lower side guide rail that determine the path of the containers. The guide fingers continuously guide the containers along the first transport path, maintaining firm contact with the upper guide rail throughout its entire length.

The first transport path portion includes multiple transition curve portions that have different curvature orientations in the handling direction. These transition curve portions allow for smooth and controlled movement of the containers along the transport path.

The container-handling apparatus also includes adjustable curve paths in the region of the transition curve portions. These curve paths can be adjusted using motor-controlled and/or closed-loop controlled adjustment devices.

The guide fingers are configured as a single piece and are hardened at least in the region of the contact surfaces. They have a triangular base surface and the contact surfaces are located on the leading side surface of the guide fingers.

The apparatus also features a concave transport pocket formed by the second guide portion of the guide fingers. This pocket engages around the outer circumference of the container, ensuring secure transportation.

Overall, this patent describes a container-handling apparatus that is specifically designed for use in a filling machine. It includes a rotor, a chain conveyor with guide fingers, and adjustable curve paths to ensure smooth and controlled movement of containers during the filling process.
