Positive control of the orientation of shelves is provided by pairs of rollers attached to the shelves which straddle a guide bars during the return run and ride within guide channels during the working run. During the transition between return and working runs at the top and bottom, shelves are held tight against bosses adjacent the sprockets. Each successive cycle pivots the shelves 180 degrees, and the shelves are symmetrical about their pivot axis.

  • Patent number: 6450238
    Abstract: The system comprises at least one conveyor tract along which a line of containers is made to move forward by a pusher action applied at one end of the line. A plurality of transport elements can be aligned on the conveyor tract and are capable of receiving at least one respective container of the line, with the containers separated from each other. The transport elements are capable of cooperating with each other in thrust transmission, so that the pushing action applied to the transport elements produces the forward movement of the line of containers while the containers themselves are kept separate from each other.

  • Patent number: 6336549
    Abstract: A multi-level conveyer mainly includes a plurality of carrier units connected at front and rear ends to two parallelly extended chains, and chain wheels provided at predetermined positions for the chains to pass there and turn to form more than one level of horizontal conveyance path on the conveyer. The multi-level conveyer can be mounted in a room with limited area while providing sufficient conveyance length and time to meet requirements in most drying operations and largely reduce power consumption required in drying.

  • Patent number: 6321895
    Abstract: In one embodiment, a conveyor comprises identical carriages and apparatus for connecting the carriages end-to-end. The carriages each include first wheel pairs supported for a rotation about spaced apart parallel axes and a second wheel pair supported for rotation about a perpendicular axis. The first and second wheel pairs are rotatably supported by self-lubricated bearings. The connection apparatus may comprise either connection rods or a wire rope. In another embodiment, the conveyor comprises identical links each including first and second link portions. The link portions are pivotally interconnected by a first connecting pin which also supports a first pair of wheels. Adjacent links are interconnected by a second connecting pin which also supports a second wheel pair. The first and second wheel pairs are rotatably supported by self-lubricated bearings.

  • Patent number: 6318543
    Abstract: A product transport system which is located predominantly within a chamber 10 (for example, an industrial oven chamber) and which comprises a pair of parallel, spaced apart conveyor chains 19. The conveyor chains are arranged to convey a plurality of transversely extending product support trays 15 through the chamber 10. Pairs of transversely spaced carriers 31 are provided to carry respective ones of the trays 15. Chain sprockets 20 are located within the chamber in alignment with the respective conveyor chains and the sprockets 20 are arranged to direct the respective conveyor chains through changes in direction (including through forward-and-return horizontal passes) within the chamber 10. Rotatable guide members 28 in the form of toothed wheels are positioned laterally adjacent to but out of alignment with respective ones of the chain sprockets 20, and a subsidiary chain drive is provided for driving each guide member 28 in synchronism with an adjacent one of the chain sprockets 20.

  • Patent number: 6112885
    Abstract: The present invention is directed to a transport apparatus for thin, board-shaped substrates, for example printed circuit boards, which are conveyed through a coating installation and the like. In order to simplify manipulation during conveying, there is provided a frame (1) for holding a substrate (7), tensioning elements (4) being arranged spaced from one another on frame members (2), lying opposite one another, of the frame (1), which tensioning elements (4) engage the edge of the substrate and tension the substrate, the frame (1) being provided with a device (16) which serves to provide connection to a conveyor belt or the like. The tension springs (4) exert a tension away from the substrate (7) in the direction of the plane of the thin substrate to avoid sagging of the substrate. FIG. (1) illustrates the transport apparatus.

  • Patent number: 5695071
    Abstract: A system and a method for sorting are provided for distributing articles, such as mail pieces or other flats, to predetermined destinations. At the destination, the particular article is raked by a raking assembly from a carrier for placement into a container. The container, when full, is gravity fed onto a discharge conveyor and automatically replaced with a new empty container. The carrier operates on two levels for delivery of articles to containers on two levels while maintaining the carriers in a horizontal position throughout the sorting process. A sloped front end of the carrier allows the articles to be transported at a rapid speed and in a continuous fashion.
