  • Patent number: 9670006
    Abstract: An apparatus for singulating products supplied in bulk, such as, for instance, fruits, potatoes, or eggs, more particularly for unround products, for instance pears or sweet peppers, comprising: an endless conveyor which extends in a transport direction (T), wherein the conveyor is provided with at least one row, extending in the transport direction, of carriers (1a; 101a) configured such that between each two successive carriers in the row a transport position for a product is formed, wherein each carrier comprises at least one roller (4; 104), arranged on a respective axis of rotation (5a, 5b; 105); wherein at least one of said rollers (4; 104) includes at least a first roller-section (21; 121) and an adjacent second roller-section (22; 122) having mutually different product engagement properties, wherein at least two successive carriers in a said row of carriers include respective rollers that each include at least a first (21; 121) and a second roller section (22; 122), wherein the second roller section

  • Patent number: 6712220
    Abstract: The invention relates to a method and apparatus for packaging products, such as vegetables and fruits, utilizing a sorting machine which method includes the steps of determining per product the characteristics of the respective products, such as, for instance, determining their weight and/or their shape; comparing the characteristics with predetermined packaging requirements; on the basis of this comparison, selecting products that do not need to be packaged; supplying the other, non-selected products to a packaging unit, which packaging unit is energized only when there is a substantially uninterrupted in-feed of the products into the packaging unit.

  • Patent number: 6674037
    Abstract: A method and apparatus for transporting and sorting flowers or other stem-shaped or elongate products with a conveyor provided with arm-fork units which are moved along a transport path in a substantially horizontal plane. In one form, the method includes taking over a substantially vertically hanging flower from a take-over position with a fork at the end of the arm-fork unit remote from the conveyor. The flowers are transported along the transport path, with the arm-fork unit in a transport position, to an apparatus for bunching the transported flowers with generally several bunching stations. The transporting takes place in the plane along at least one detector for detecting at least one respective flower characteristic, whereby detection signals are obtained. The detection signals are processed in a processing unit into corresponding selection signals.
