Abstract: A filling machine for containers simultaneously fills an array of containers, for examples immediately following depalletizing, and includes motor driven positioners for the nozzles to accommodate changes in the size of container being run. The containers are laterally abutted to occupy evenly spaced container positions, and the array can be compressed by a contoured push bar to force the entire array into registry. The nozzles are flexibly coupled to a source of material to be discharged into the containers, and are mechanically moved by actuators that displace at least a subset of the nozzles along the axes of the array. In this way the nozzles are moved into registry with the container array. The nozzles are also vertically movable relative to the containers, and each includes a valve opened by contact with a respective container, for discharging only into occupied container positions and not voids in the array.

Abstract: Open containers having uniform dimensions are handled in a group for loading of ballast and/or for filling with container contents prior to sealing. The containers are provided upright on a substantially unobstructed surface and are forced into a substantially contiguous array by inward pressure on the array in at least one direction perpendicular to the longitudinal axes of the containers. Compressing the array of containers in this manner moves the containers into immediately contiguous regular positions in a resulting container array, which is aligned in registry with dispensing orifices. One or more movable sweep arms which may cooperate with fixed walls laterally bounding the conveying surface are used to compress the array. The sweep arms and the fixed walls are scalloped to form receptacles defining a closest possible positioning of the peripheral containers, which during compression cause adjacent inward containers to become correctly positioned. Nozzles coupled to a material dispenser (e.g.

Abstract: Lightweight containers such as polyethylene terephthalate (PET) beverage bottles are rendered stable for conveyance on a horizontal conveyor by addition of water ballast. Ballast in the amount of about 3 to 10% of the bottle volume is sufficient to enable increased production line speed with fewer bottle jams due to the lightweight bottles falling over. The bottles are arranged upright, for example at the outlet of a depalletizer, and loaded with ballast from a reservoir or pressurized supply of water. Preferably, the bottles are loaded in a group and a plurality of valves having valve bodies on a movable common support open simultaneously. The ballast is removed at the bottle rinsing station, which inverts the bottles to drain the ballast as well as rinse water.
