Abstract
A rotary volumetric piston dispenser is provided which receives material from a manifold assembly, portions that material while it traverses a path to a dispensing location, and dispenses the portioned material at the dispensing location. The rotary volumetric piston dispenser is suitable for timed communication with a movable belt or the like in order to deposit the portioned material according to a predetermined sequence. A camming assembly is also provided which is suitable for use within the rotary volumetric piston dispenser, the camming assembly including a cam track assembly having an adjustable camming pathway in order to vary the radial position of a radially movable element such as a piston while the element moves in a pattern that generally corresponds to the cam track assembly. The rotary volumetric piston dispenser is especially suitable for use in dispensing condiments, whether they be wet or dry, onto a moving surface, such as a plurality of proteinaceous patties spaced along a conveyor belt. One portion of the cam track assembly extends the radially moveable element outward beyond a cylinder of the dispenser to permit a cleaning fluid to be directed outwardly throug…
