Moving Items To Sorting Means In Spaced Relation Lengthwise Of Feed Path Patents (Class 209/934)
  • Publication number: 20040016684
    Abstract: The present invention reveals a sorting system for use in manual sorting, which presents a detached ephemeral display moving in a manner corresponding to the movement of the article, by which an article to be sorted can be quickly and easily identified. To accomplish its purpose, the device comprises: feed conveyors; a switching unit; optical readers positioned to capture destination indicia affixed to each article; a detached moving display which remains close to the article to be sorted and presents information representative of the article's destination location; a destination location which signals when a related article is approaching; and a controller capable of assigning destination locations and controlling display devices.

  • Patent number: 6179129
    Abstract: An article transporting, and preferably also color and/or weight sorting, assembly and method, support the articles (.g. apples or like pieces of fruit), and effect precise rotation (e.g. within about 5°) of all apples transported thereby. This allows accurate determination of the apple's color by color sensing equipment (e.g. a color camera). The assembly comprises a support element, and two sets of cones mounted to the support by rotatable shafts, each set comprising first and second cones having a tapered exterior surface, the cones on each shaft facing each other and tapering to an imaginary substantially common midpoint. The cones support an apple essentially without the apple engaging the shaft. The cones may be of soft yieldable plastic or rubber with a first taper of about 25-35° (e.g. about 28°), and optionally one or more steps of different taper.

  • Patent number: 5669511
    Abstract: A grain sorting apparatus includes a conveyor belt mechanism for conveying grains, fed by a feed mechanism onto a conveying surface separately from each other at an upstream region with respect to a conveying direction, to a downstream end so that the grains are discriminated and sorted by a discriminating mechanism and a sorting mechanism when dropping from the downstream end along a predetermined path, the belt mechanism being disposed so that the conveying surface thereof declines as going downstream with respect to the conveying direction to prevent the grains being carried by the belt mechanism from rolling toward the upstream direction on the conveying surface of the belt mechanism. It is therefore possible to prevent the grains from rolling on the conveying surface of the conveyor belt mechanism toward the upstream direction relative to the conveying surface of the conveyor belt even when a conveying velocity of the conveyor belt mechanism is high.

  • Patent number: 5641072
    Abstract: The present invention provides a method for sorting post-consumed bottles exactly and efficiently and an apparatus for carrying out the method. The sorting apparatus comprises a supply section, a separating section, a detecting section comprising a first image pickup camera for detecting the size and contour of each post-consumed bottle and a second image pickup camera for high speed detection of color by a defined image pickup utilizing data from the first image pickup camera, a sorting section for sorting and discharging only post-consumed bottles already classified to sorting containers preliminarily placed in accordance with data received from the detecting section, and a control section for controlling a series of operations timely. Since the scope of the image pickup for detecting color of the post-consumed bottles is defined in accordance with the data from the detecting section, picture processing at a high speed is achieved resulting in remarkable sorting performance.

  • Patent number: 5482166
    Abstract: A sorting system is disclosed for reclaiming lean meat from highfat meat trimmings. The sorting system includes a meat dicing machine which receives laterally extending whole meat trimmings and which dices such meat trimmings without grinding or extruding, and without disturbing the lateral distribution of the meat. This results in a lateral distribution of meat trimmings, without requiring vibratory distribution which is disfavored in meat processing plants. A wide-belt inspection conveyor is positioned at the downstream end of the meat dicing machine to receive the laterally distributed meat dices. The wide-belt inspection conveyor operates at a greater linear speed than does the meat dicing machine to longitudinally space the meat dices from each other. An optical inspection and sorting station is positioned at the downstream end of the wide-belt inspection conveyor to differentiate relatively lean meat dices from relatively fatty meat dices and to separate such meat dices from each other.

    Abstract: Apparatus and method are provided for inspecting finish dimensions of and detecting finish defects on containers moving sequentially in a predetermined path. More than one container can be inspected simultaneously. The apparatus includes one or more inspection gauges suspended above the container path. A transport system is provided for aiding in moving containers through the gauges and simultaneously axially rotating the containers about a vertical axis. Rotation of the containers allows the inspection gauges to inspect the entire circumference of the containers at one or more levels on the container simultaneously. Defective containers are detected when the relative separation distance between the gauge plates of the inspection gauge falls outside predetermined limits. If a defective container is detected, a rejection assembly may be activated to physically remove the defective container from the container path.

    Abstract: A can sorting apparatus is described for processing over 600 filled metal cans per minute. An infeed conveyor moves alongside a main conveyor in which the main conveyor is moving at a speed greater than the infeed conveyor. A transverse diverter directs the moving cans from the infeed conveyor to the main conveyor causing the cans to be automatically spaced as they move from the infeed conveyor to the main conveyor. The cans move past a sensing station to individually identify the cans and determine which cans are to be separated from the others. An overhead separating conveyor extends across the main conveyor at a separating station. An overhead electromagnet is positioned at the separating station to selectively lift a can from the main conveyor and bias the can upward against the lower flight of the overhead conveyor. The overhead conveyor then directs the lifted can transversely from the single line of filled cans to perform the separation of the cans.
