    Abstract: A product stabilizing conveyor system for a continuous, segmented lane curvilinear conveyor having linear and curvilinear sections. The conveyor is configured to transport small products, e.g. 0.46 diameter glass vials, in circular fashion. Wedged-shaped diverter elements are positioned at the juncture between a linear section and curvilinear section of the conveyor, after the registry and outfeed area. The diverter elements serve to direct the minute vials away from the larger interstices which form on the outbound paths of travel of the curvilinear section and towards the smaller sized interstices on the inboard paths of travel. Diverting the vials in this manner ensures they do not cross over the edges of the larger sized interstices and fall over onto the conveyor surface. Instead they remain upright as they travel around the curvilinear section and hence around the entire conveyor.

    Abstract: Holes are removed from nested product patterns by conveying products on a conveyance mechanism (12) through an infeed section (14) in nested pattern streams (a1, a2, b1, b2), into a narrowing section (24) of a width less than one and one half the product diameter. After the narrowing section (24), the product streams (a11, a21, b11, b21) enter into an expansion section (44) where products move into a side-by-side product stream (a12, a22, b12, b22). Thereafter, nested product streams (a13, a23, b13, b23) are formed, which can be combined to form nested product streams (A, B) which can be further processed as desired.

  • Patent number: 6896474
    Abstract: Associated to the first product of each group or slug of products being formed is a first engagement element which follows the movement of advance of said first product, preventing it from falling forwards in the direction of advance. In such conditions, the products are made to advance according to a stacking path that is substantially horizontal, setting them up against the first product, and thus determining the formation of groups or slugs of products and counting the number of products stacked. When the number of products stacked reaches the desired value, the last product in the group is engaged by a second engagement element which exerts an action of thrust in a forward direction on the slug of products thus formed, so causing separation thereof from the first product of a new slug being formed in the stacking structure. The stacking operation is performed on the products, which are set on edge after being tipped starting from a previous substantially horizontal position of advance.

  • Patent number: 6575287
    Abstract: A product conveying and accumulation system is provided for use with products of various sizes, shapes, and stability characteristics. The system comprises multiple moving conveyors, including a first conveyor which transports product from an upstream location. This same conveyor or another conveyor delivers product to a downstream location. An accumulator conveyor, traveling at a substantially similar speed or a designated variable speed as the first conveyor or conveyors, is aligned in the same plane as, is adjacent to, and may mate with the first conveyor at a predetermined location for contiguous movement in the same direction as the first conveyor at this predetermined location. A product guide is provided which allows for the movement of product from the upstream to downstream locations during normal operation and directs product to the accumulator section of the second conveyor when there is a disruption or malfunction downstream.

  • Patent number: 6523674
    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.

  • Patent number: 6328151
    Abstract: The invention is directed to a method and apparatus for combining randomly oriented containers on a conveyor into single file. The apparatus includes a pressureless combining conveyor having at least two or more conveyor sections adjacent to one another, and angled about the axis of a guide rail. The substantially linear guide rail extends at an angle across the combining conveyor. The guide rail is constructed such that the lower part of a container which starts to fall toward the guide rail contacts the guide rail first, then tilts toward the guide rail, touching the guide rail at a height of the container near the center of gravity of the container, and then returning to its stable position. The container's center of gravity always remains within its stability region. The apparatus includes an input conveyor to supply a plurality of containers having no specific orientation, and an input guide rail section to guide moving containers to one side of the input conveyor.
