Salzgitter has been granted a patent for a filling machine that includes a rotor with multiple container-filling positions, an inflow star, and a linear conveyor. The machine has an interface with a curved portion that receives the container after it has been filled but before it is closed, and conveys it towards the linear conveyor. The interface has three transition curve portions, with the second one having a curvature opposite to the first and third portions.

The patent is granted for a filling machine with a curved interface
A recently granted patent (Publication Number: US11760618B2) describes an apparatus for filling containers with liquid content. The apparatus includes a filling machine with a rotor that has multiple container-filling positions. The containers are transferred to the rotor from an inflow star at an inflow point and are received by a linear conveyor at an outflow point after being filled but before being closed. The processing region between the inflow and outflow points is defined by a circular arc.
The apparatus also features an interface with a curved portion that receives the containers at the outflow point and conveys them towards the linear conveyor. The curved portion of the interface consists of first, second, and third transition curve portions, with the second transition curve portion having a curvature that is opposite in sign from the first and third transition curve portions. The interface may also include a straight portion that follows the curved portion.
The curved portion of the interface can be adjusted to define a customizable curve path using multiple transition-curve portions. Guide rails are provided along the interface to guide the containers, and first and second guide rails are flush with each other along the linear conveyor. The curved portion of the interface can be formed by various curves, such as a clothoid, Bloss curve, polynomial, or one or more trigonometric functions.
In addition, the patent describes the positioning of the linear conveyor along a line that is tangent to a circle defined by the rotor at a tangent point. The circle is formed by radial lines extending between the circle's center and the inflow point, tangent point, and outflow point. The angles defined by these radial lines determine the positioning of the linear conveyor.
Overall, this patented apparatus provides an efficient and customizable solution for filling containers with liquid content. The curved interface and adjustable curve path allow for smooth transfer of containers from the rotor to the linear conveyor, enhancing the efficiency of the filling process.
