摘要： A pneumatic accumulation conveyor has an anti-singulation control capable of deactivating the drive of a zone if the product sensor for that zone and substantially all of the product sensors downstream of that zone sense the presence of product in order to produce an accumulation portion with no zones actuated and is capable of activating the drive of a zone if any of the drives downstream of the associated zone are actuated in order to produce a transport portion in which all zones upstream of any actuated drive are actuated to transport product without singulation of any upstream grouped product. The accumulation conveyor is controlled by retractable product sensors positioned at particular locations along the product conveyor in order to sense the presence of product at the particular locations. Each of the product sensors includes an arm that is selectively positioned in the path of the product being conveyed by the product conveyor, a switch having an actuation member juxtaposed with the arm and a force-producing connection from a drive actuator of a downstream zone in order to move the arm from a position in the path of the product being conveyed to a retracted position. A mode control is provided for selecting one of first, second and third modes. In a first mode, the control actuates a discharge conveyor section and causes all sensors to be retracted from their sensing position to provide a slug discharge mode in order to clear out accumulated product without singulation. In a second mode, the control actuates the discharge conveyor but extends one group of sensors to a sensing position. This provides singulation between packages at the location of the sensor rollers to provide a singulation discharge mode in which gaps are drawn between packages. In a third mode, the discharge conveyor is deactuated and all sensors are allowed to be in their extended position in order to accumulate product.

摘要： A conveyor system includes an accumulation conveyor that is particularly useful in a location outbound of a sortation spur in combination with a receiving conveyor which receives products from the accumulation conveyor at a generally constant rate. The accumulation conveyor includes a plurality of powered rollers that are selectively actuatable in groups of tandemly arranged zones in order to convey product to the receiving conveyor. A product sensor associated with each zone senses the presence of product in that zone, and a control that is responsive to the product sensor actuates all of the rollers associated with zones upstream of any sensor that is not sensing product in order to transport product to the receiving conveyor without singulation, yet provide an accumulation capability. The control is pneumatic and uses pilot-actuated valves configured in a manner that connects the associated roller drive actuator directly with a source of pneumatic fluid in order to provide an exceptionally responsive control.

摘要： An article unscrambler and aligner is disclosed which receives articles of different sizes in random order and position, and using plural side-by-side lanes each of which lanes has driven article transport rollers at different speeds, which speeds are uniform for the length of the lane, but are progressively higher in each lane toward one side of the unscrambler in order to provide a lateral linear speed increase. This speed increase causes separation and rotation of the articles and also causes them to arrange in single file along one side of the unscrambler's surface and so discharge them onto a conveyor at the end of the unscrambler remote from that at which the articles were received. One or more lanes are composed of rollers of tapered diameter in order to make the lateral speed increase more uniform.

摘要： An accumulation conveyor includes a product sensor that is positioned along the conveyor at a particular zone for sensing the presence of product at that zone and for causing actuation of the zone upstream of that product sensor with respect to product movement along the accumulation conveyor. The product sensor includes an arm that is selectively positioned in the path of product being conveyed, a switch having an actuation member juxtaposed with the arm, and a force-producing member responsive to actuation of the downstream zone actuator in order to apply a force to the switch and, in turn, retract the sensor. This may be accomplished by physically locating the product sensor within the downstream zone and providing an actuator for that downstream zone that is mechanically coupled to the product sensor physically located within that zone. When the actuator is actuated, it retracts the product sensor from the path of movement of product along the accumulation conveyor concurrently with actuation of the downstream zone. The switch may be selectively mounted either to a stationary member or to the downstream actuator. If the switch is mounted to the stationary member, the associated sensing member is not responsive to actuation of the downstream actuator and a non-retractable sensor function is achieved. If the switch is mounted to the actuator, actuation thereof will retract the sensing member from the path of movement of the product along the accumulation conveyor. Thus, each product sensor may be made into either a retractable sensor or a non-retractable sensor. Each actuator includes a moveable member that reciprocates with respect to a stationary support member to which is mounted a signal manifold that interconnects with signal manifolds of adjacent control devices and with a force-producing device for reciprocating the moveable member of that actuator. The accumulation conveyor further includes a drive assembly that is entirely supported by the side rails of the accumulation conveyor in order to thereby be positionable at substantially any longitudinal location along the product conveying surface.

摘要： An active high volume storage carousel provides an improved drive system. The carousel includes a driven conveyor, which defines a continuous path and includes at least one container handling location along the continuous path. A track rail extends around the continuous path and provides vertical support for a plurality of storage columns, which are drivingly coupled to the conveyor by couplers. When the storage columns are moved through the container handling location, at least one of the storage columns is drivingly decoupled from the driven conveyor so that the decoupled storage column can be easily loaded with or unloaded of containers.
