  • Patent number: 8181770
    Abstract: A downloader conveyor is described and claimed. The downloader conveyor comprises an endless belt to which a plurality of cups is pivotally attached. The cups are adapted to receive apples or like relatively delicate objects. As the cups containing the apples descend into the bin, the cups rotate so as to permit the apples or other objects to roll out of or exit from the cups and to retard the cup acceleration. Each apple engages a skirt, which breaks the fall of the exiting apple. A distal end of the skirt can be arranged to scrape over the bin floor or scrape over the top of apples or other objects already placed in the bin, so as to again break the fall of the apple so that the apple is placed in the bin without substantial freefall.

  • Patent number: 5435430
    Abstract: There is utilized a particular bucket conveyor apparatus for the transport of fragile articles such as cookies and crackers from an input feed point to a multiple number of discharge areas. At the discharge areas the bucket conveyors are tilted rearwardly to spread the fragile crackers and cookies over a lower transverse belt or vibrating conveyor. In the operation of the apparatus each of the buckets is filled initially to less than about 50 percent of its volume. In this way if there is not an available discharge point, the bucket can once again go through the cycle before it would reach a point of overflowing. When the buckets are in a full condition, they will empty half or more of their contents onto a storage station conveyor prior to passing the input feed point. This bucket conveyor mechanism lends itself to a high degree of computerized control.

  • Patent number: 4607745
    Abstract: A bucket conveyor wherein the buckets are pivotable about transverse horizontal axes and have first cam faces which slope upwardly and rearwardly counter to the direction of movement of the buckets. The cam faces of successive buckets can be engaged by a roller which can be moved downwardly to tilt the buckets. The buckets have straight second cam faces which come into contact with the underside of a stationary rail in response to partial tilting of the buckets to maintain the buckets in tilted positions during travel along a selected portion of their path. The downstream end of the rail forms a ramp to effect a gradual pivoting of successive buckets back to untilted positions.

  • Patent number: 4266696
    Abstract: A guide cylinder with its axis directed in the upper and lower directions is provided on the bottom of a hopper. In the guide cylinder are allowed to pass a plurality of measuring containers supported by an endless conveyor which is moving upwardly from the bottom of the hopper, so that bulk foods in the hopper are scooped up into the measuring containers. While the measuring container is still over the hopper, excess bulk foods are caused to fall onto the hopper by way of a suitable shaking operation. Thereafter, the bulk foods are conveyed out of the hopper by the conveyor, and exhausted at an exhausting station by turning the measuring container upside down. The distance between the measuring containers provided on the endless conveyor is made smaller than the length of the guide cylinder so that at least one of the measuring containers is always present in said guide cylinder. This enables the measuring containers to further serve as a bottom covering of the hopper.
