Abstract: A camera based vision system that recognizes and maximizes belt area utilization. A plurality of cameras are positioned at flow entry points of feed conveyors and at the singulator. The control algorithm recognizes individual items area, the rate at which individual objects are passing, and the area utilization of the collector belt. The video camera and computer based conveyor package management system monitor and control the number and size of the packages present on the infeed conveyors, collector conveyor, singulator conveyor and sorting conveyor in a package handling system wherein the camera data is used to measure the available area or space on the conveyors to maintain a desired density of packages on selected conveyor(s). The conveyor speed is controlled as a function of occupancy on a collector or just prior to a singulator or receiver.

Abstract: A typing tunnel off-loading and sorting system includes an off-loading conveyor, cameras and photoelectric eye. The overhead cameras detect the item size and whether it is cubic in nature and type and size of its footprint. An in-line slide sorter having alternating conveyor rollers and pop-up belts pass through to, or divert articles from, a downstream conveyor. The vision based system may also be used to detect space between articles and insert articles in the unoccupied space.

Abstract: Conveyor glide plates inserted between conveyor rollers provide support between the rollers. The glide plate main body includes forward and rear flexible flaps forming a leading edge and a trailing edge extending from the main body which includes an attachment member for cooperatively engaging a conveyor roller support member such as a clip or bracket used to affix the rollers to the conveyor. The front portion of the forward distal end of the glide plate includes a concave curve extending from the leading edge downward forming a turned-up lip extending from the main body of the glide plate following the adjacent roller. A rear flap having a distal end angled downward slightly at the trailing edge extends toward a following roller or following glide plate. The width of the glide plate is selected based on the width of the conveyor or length of the roller.

Abstract: This invention relates generally to a conveyor assembly for separating and aligning parcels, packages, bags and other articles prior to processing with a singulator. The stepped wall assembly includes a low friction conveying surface having both forward and lateral conveying forces for moving articles toward a lateral sidewall and a downstream conveyor. A series of offsets disposed between straight and diverging sidewalls force parcels toward the center of the conveyor against the lateral forces of the low friction conveying surface gradually separating and converging the parcels toward a selected sidewall of the conveyor and in line with a singulator apparatus.

Abstract: A conveyor assembly insertable within a conveying system including a low friction conveying surface having both forward and lateral conveying forces for moving articles toward a parallel lateral sidewall and a downstream conveyor. A first diverging sidewall gradually converges parcels toward the center of the conveyor. An inwardly directed offset extends from a first diverging sidewall to a second lateral sidewall for shifting parcels inwardly toward a second lateral sidewall. A raised high friction conveying surface or rail belt extends along an outer edge of the low friction conveyor. At least a portion of the high friction belt is raised above the surface of the adjacent conveying surface in flow communication with the low friction conveying surface. Parcels contacting the high friction belt are prevented from shifting over toward the sidewall and parcels having a center of gravity outside the tipover point fall over the belt onto a recirculation conveyor.

Abstract: This invention relates generally to a conveyor system including a speed control slide sorter system disposed perpendicular to a pass through conveyor wherein the speed control improves efficiency in loading and utilizing available area on the belt and selects the conveyor speed to induce a diverter action according to sensors which detect portions of the irregular shaped packages, parcels, and bags which can be engaged by the pop-up belt at a selected time to slow the conveyor and engage the pop-up transfer conveyor without stopping the conveyor.

Abstract: A singulator conveyor system having conveyors arranged in adjacent parallel configuration for separating and orienting side-by-side packages having unequal loading, different sized packages (e.g., boxes, flats and softpacks), partially filled bags, long and slender articles, and packages having an offset center of gravity. Two of more small items abreast of one another are separated while permitting large items to pass thorough the singulator even when the item is a large bag of small items. A first conveyor lane includes a high friction surface for conveying articles forward along a vertical side wall. A second conveyor adjacent thereto has a low friction surface including both forward and lateral conveying forces urging parcels forward and away from the first conveyor and side wall toward a third conveyor having a high friction conveying surface wherein the longitudinal edge of the second conveyor is below the first conveyor and above the third conveyor.

Abstract: A sorter conveyor system includes a conveyor forming an upwardly facing support surface for conveying objects. The support surface includes slots oriented transversely to the conveying direction and a plurality of shoe assemblies mounted for sliding movement along respective slots for transversely discharging objects from the conveying surface. Each shoe assembly includes a carrier disposed below the conveying surface, and a shoe disposed above the support surface. The shoe and the carrier together form a releasable connection therebetween. The releasable connection is configured to enable the shoe, in response to an undesirable force applied thereto, to detach completely from the carrier without breakage or failure of any part of the shoe assembly, and to be manually reattached without the use of tools or special skills. Various related methods are additionally disclosed.

Abstract: A conveyor system can includes a feed conveyor, a declined conveyor, and an inclined conveyor. A declined stationary surface is suspended above the declined conveyor and positioned to exert a counter-moment on the articles related to the weight of the stationary support surface and the coefficient of sliding friction of the stationary support surface that is sufficient to resist forward rotation of the articles down the declined conveyor. An inclined stationary support surface is suspended above the inclined conveyor and positioned to exert a forward-moment on the articles related to the weight of the stationary support surface and the coefficient of sliding friction of the stationary support surface that is sufficient to resist counter-rotation of the articles that results in movement of the articles down the inclined conveyor. The vertical height of the stationary surfaces can be adjusted. A related method is also described.
