  • Patent number: 4934510
    Abstract: A supply conveyor has a support surface for conveying glass bottles supported at their bottoms in upright condition and feed them sequentially to a gap between the supply conveyor and a delivery conveyor, also having a support surface for conveying the bottles supported at their bottoms in upright condition and feeding them away from the gap. An intermediate conveyor accelerates the bottles across the gap from the slower speed of the supply conveyor to the high speed of the delivery conveyor and deposits them on the delivery conveyor at the requisite high speed an in upright condition and, as well, cause the bottles to be deposited on the delivery conveyor in properly spaced relation to allow the requisite inspection of the bottles to be made.

  • Patent number: 4680463
    Abstract: The invention relates to an apparatus for checking containers, e.g. bottles or pots by means of a transport apparatus for transporting the containers along a predetermined path and a lighting apparatus positioned at a side of said path, e.g. at least one flash light means, and a sensing apparatus, e.g. at least one video camera positioned on a corresponding position, said transport apparatus being provided, in the area of said lighting apparatus and said sensing apparatus a part, in which the containers are hung by their collars. The invention proposes to adapt an apparatus of the type mentioned in the preamble in such a way that in said part of said transport apparatus the path is rectilinear, thus avoiding the need of using means to counteract the oblique position necessary in prior art apparatus, in which the path is curved, and avoiding mechanical load due to centrifugal forces.
