Abstract: A reject bottle detection and ejection apparatus has a plurality of sensors positioned along the length of a belt conveyor that senses whether a bottle conveyed by the conveyor is positioned in an upright orientation, in an inverted orientation, in a sideways orientation, in a slanted orientation, or whether the bottle is damaged, and an air jet nozzle positioned downstream of the plurality of sensors that selectively emits a jet of air at a bottle conveyed past the air jet that has been sensed to be not in the upright orientation or to be damaged, thus removing the bottle from the conveyor.

Abstract: A pallet dispenser can receive a vertical stack of skewed or misaligned pallets in an interior of a frame of the pallet dispenser and align the pallets as they are sequentially dispensed from the pallet dispenser onto a conveyor below the pallet dispenser. The pallet dispenser that can be quickly manually changed over to accommodate pallets of different sizes and vertically dispense the pallets one by one onto a conveyor below the pallet dispenser. The pallet dispenser is provided-with a quick, manual change over that enables the pallet dispenser to be quickly adjusted to accommodate a vertical stack of large or small pallets to be reoriented and dispensed by the pallet dispenser onto a separate conveyor without appreciable downtime of the pallet dispenser or the conveyor with which it is used.

Abstract: A series of pneumatically controlled linear reciprocating actuators adjust the lateral spacing of a conveyor slot between opposed flanges of an air conveyor employed in conveying plastic bottles suspended by their neck rings in the conveyor slot to quickly change over the air conveyor for conveying plastic bottles of different neck and neck ring diameters.

Abstract: An infeed assembly for use with an air conveyor system. The infeed assembly has a guide mechanism configured for engaging an article, such as a lightweight plastic bottle, and guiding it as it is conveyed through the conveyor system, a plurality of air jet conveyor nozzles, a plenum in fluid communication with the conveyor nozzles for forcing pressurized air through the conveyor nozzles and adjacent the guide mechanism in a manner to push the article downstream along the guide mechanism from an inlet end of the guide mechanism to an outlet end of the guide mechanism. The infeed assembly comprises an article alignment mechanism, at least one air jet infeed nozzle adjacent the article alignment mechanism, and at least one conduit providing fluid communication between the plenum and the infeed nozzle. The article alignment mechanism is positionable adjacent the inlet end of the guide mechanism and is configured for directing the article into the inlet end of the guide mechanism.

Abstract: An air conveyor transitional section connects an upstream air conveyor section to a downstream air conveyor section that is not collinear with the upstream air conveyor section. The air conveyor transitional section includes a pair of elongated members having opposed inner edges and upper surfaces adjacent the inner edges. The inner edges of the elongated members are laterally spaced to define a slot that extends in a downstream direction of the air conveyor. The upstream air conveyor section, the transitional section, and the downstream air conveyor section are all configured for conveying containers in the downstream direction. Each container has a neck ring with an outer diameter dimension. The inner edges of the elongated members are laterally spaced by a distance smaller than the container neck ring outer diameter dimension so that the upper surfaces provide slidable support for the container neck rings.
