Abstract: A reject bottle detection and ejection apparatus comprises 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 row former of a conveying system is provided with a plurality of protrusions projecting from a side of a row forming arm that engage with portions of objects arranged in a row and pushed before the arm across a row forming table surface and prevent relative movement of the objects in the row.

Abstract: A conveyor system comprises a novel row former, a novel array rake and a novel sweep mechanism that are all designed to prevent relative movement between objects arranged in rows and then formed in two dimensional arrays of the objects as the objects are moved through the conveyor system, where the objects have triangular shaped cross sections.

Abstract: A conveyor system includes a diverter positioned between an upstream conveyor and several downstream conveyors and splits or switches a procession of objects conveyed by the upstream conveyor to one of the downstream conveyors where the downstream conveyors are provided with a plurality of sensors along their lengths that detect the presence or absence of objects on the downstream conveyors at different positions along their lengths and supply signals to the diverter to control the diverter to switch between the downstream conveyors to direct the objects conveyed by the upstream conveyor to the one of the downstream conveyors having fewer objects being conveyed by the conveyor and also controls the number of objects delivered by the diverter to the downstream conveyors.

Abstract: A transition between two sections of belt conveyors transfers a series of objects conveyed on the ending section of one conveyor through a pair of guide rails laterally over to a beginning section of the second conveyor. A source of vacuum is positioned between the ending section of the one conveyor and the beginning section of the second conveyor and holds the conveyed objects to the two conveyor surfaces as the objects are transferred between the two surfaces and thereby eliminates the problem of one or more conveyed objects falling over as they are transferred from the one conveyor surface to the second conveyor surface.

Abstract: A conveyor system includes a diverter positioned between an upstream conveyor and a pair of downstream conveyors and splits or switches a procession of objects conveyed by the upstream conveyor to one of the two downstream conveyors where both downstream conveyors are provided with a plurality of sensors along their lengths that detect the presence or absence of objects on the downstream conveyors at different positions along their lengths and supply signals to the diverter to control the diverter to switch between the two downstream conveyors to direct the objects conveyed by the upstream conveyor to the one of the two downstream conveyors having fewer objects being conveyed by the conveyor and also controls the speed of the upstream conveyor.

Abstract: A row former of a conveying system is provided with a plurality of protrusions projecting from a side of a row forming arm that engage with portions of objects arranged in a row and pushed before the arm across a row forming table surface and prevent relative movement of the objects in the row.

Abstract: A conveyor system comprises pairs of vertically spaced and horizontally oriented pulleys and belts that are positioned on opposite sides of a conveyor path. The belts wrap around the pulleys and engage with opposite sides of an object being conveyed by the conveyor, for example an empty plastic blow molded bottle, and convey the object along the conveyor path between the belts. A vertical adjustment mechanism quickly adjusts the vertical positioning of the pairs of pulleys and belts on each side of the conveyor path to quickly adapt the conveyor for conveying different sized objects.

Abstract: An air flow control mechanism for a multi-channel air conveyor enables the flow rate of air ejected from air outlet orifices of inner channels of the multi-channel air conveyor to be adjusted without changing the flow of air ejected from air outlet orifices of the outer pair of air conveyor channels of the multi-channel air conveyor.

Abstract: A spacing tool is adapted for use with a conveyor that conveys plastic bottle containers of the type having a neck ring, a neck below the neck ring, and a body below the neck. The conveyor has a pair of support flanges that are spaced laterally from one another by a distance smaller than an outer diameter dimension of each container neck ring, but larger than an outer diameter dimension of each container neck. Thus, each container can be supported between the flanges with its neck ring in engagement with upper surfaces of the flanges. The conveyor has a pair of container guide rails that are spaced from one another by a distance larger than an outer diameter dimension of each container body so that each container can move along the conveyor between the guide rails. The spacing tool comprises a spacing member having a head portion, a neck portion below the head portion, and a spacing block below the neck portion. The head portion has a first outer diameter dimension larger than the spacing between the flanges.

Abstract: An apparatus that is one part of a conveying system for transferring objects, such as bottles, where the apparatus arranges the objects in layers on a pallet is improved by the addition of sensors that provide early indications of movements of component parts of the apparatus to a control unit of the apparatus where the signals are used in a more time efficient operation of the apparatus.

Abstract: A two axis bottle guide rail change over apparatus for an air conveyor supports a pair of guide rails and is operable to simultaneously adjust a lateral spacing between the pair of guide rails and/or simultaneously adjust a vertical positioning of the pair of guide rails relative to the air conveyor.

Abstract: A braking system is provided along one of a pair of guide rails of an air conveyor that transports plastic bottles along a pathway between the pair of guide rails. The braking system is selectively actuated to move into the pathway defined by the guide rails decreasing its width and positioning a stop of the braking system in the pathway where it will engage with bottles conveyed by the air conveyor slowing and eventually stopping the bottles.

Abstract: An apparatus that is one part of a conveying system for transferring objects, such as bottles, removes layers of the objects from a pallet on which the layers have been stacked or, in reverse operation, arranges the objects in layers stacked on one another on a pallet. The apparatus may be employed to depalletize objects or to palletize objects, wherein in the depalletizing mode of operation the apparatus has a slipsheet retainer that holds a slipsheet below a layer of objects being depalletized from the stacked layers of objects on the pallet and prevents the slipsheet from moving with the layer of objects as the layer of objects is depalletized.

Abstract: A multichannel pivoting coupling between an upstream multichannel air conveyor and a downstream multichannel air conveyor includes a mechanism that can be selectively controlled to simultaneously adjust the lateral width dimensions of the slots between opposed flanges of the coupling to coincide with adjustments in the lateral width dimensions of the slots between the opposed flanges of the upstream and downstream multichannel air conveyors. The multichannel air conveyors of the type employed with the pivoting coupling apparatus convey streams of plastic bottles suspended by their neck rings in the slots and the lateral spacing between pairs of flanges that define the slots can be quickly changed over for conveying plastic bottles of different neck dimensions and different neck ring diameters.
