  • Patent number: 9027742
    Abstract: “CONVEYOR SYSTEM WITH DIFFERENT APPLICATIONS AND ISOLATION OF THE CONVEYED PRODUCT IN RELATION TO THE DRIVE SYSTEM”, is a conveyor for grains, seeds, fruit, granulated and ground products and similar products. The conveyor has different applications and isolates the product conveyed from the drive system. There are two or more tubes, and in each set of tubes there is a swivel with a drive system using roller chain, chain, cable, belt, et cetera. In this manner, the drive system is isolated from the product, avoiding mechanical damages, contamination, and also increasing the performance of the system.

  • Patent number: 8794429
    Abstract: A pan section for combined conveying and winning apparatuses having a bottom run and a top run for guiding driver elements of a conveyor chain, as well as a welded frame structure which has two side cheeks which consist of one-piece rolled profiles. The rolled profiles have a constant profile shape with a bottom leg and a top leg, which are angled outwards in the assembled state, and an intermediate leg being provided with an offset for supporting and welding at least one intermediate plate. The pan section further includes a substructure connected to the bottom leg of the rolled profiles to connect both bottom legs to one another at a distance from the intermediate bottom. The substructure also has mounting pieces positioned at the ends below the bottom legs for transverse-force transmission means.

  • Publication number: 20130207443
    Abstract: An armored face conveyor includes a plurality of line pans positioned adjacent to one another, a plurality of flight bars, and a connecting member. Each line pan includes a race having an outer race face and an inner race face. The plurality of flight bars extend laterally across the line pans and are received by the race. Each flight bar includes an end having an upper guide surface and a lower guide surface. The connecting member extends through the plurality of flight-bars and couples the flight-bars to one another. Lateral movement of any one of the flight-bars that causes the upper guide surface to contact the outer race face substantially simultaneously causes the lower guide surface to contact the inner race face.

  • Publication number: 20120080289
    Abstract: A trough pan with an upper strand trough and to an upper strand trough for a trough pan of a scraper chain conveyor, with two side profiles, and with a trough bottom. The trough bottom has two side edges and two end edges which have at least partially a wavy boundary line and which are provided at the transition of a top side into the end edge with a chamfer having a chamfer angle. In order to improve the upper strand troughs and the trough pans equipped with these in terms of the problem of the penetration of fine coal into the intermediate gap of the bearing region between the trough bottom and intermediate bottom, the end edges are provided with a bevel between the chamfer and an underside, the bevel sloping more steeply than the chamfer.

  • Patent number: 7975837
    Abstract: A conveyor (10) includes an elongate tray (12) for supporting goods thereon, and a powered drive (16) to move goods along the tray. In one embodiment, a gate (24) is supported on this tray for closing an opening in the tray or for opening to allow goods to drop through the tray opening. The gate has a first magnet (34) supported thereon. A gate drive (22) moves the gate between the open and closed positions, and has a second magnet (32) which cooperates with the first magnet such that the magnets separate if the gate encounters an obstruction when closing.

    Abstract: A skirt for a material transport system, eg conveyor belt (104), includes liner plates (111, 112) mounted on the conveyor side of body (200). Removal of certain plates (112) only requires access via the side of body (200) away from conveyor (104). To remove plate (112) requires removal of its support member (210) as well and so provides an aperture through which a workman can insert his hand to remove further plates (111, 112). Member (210) may be hel to body (200) using wedges inserted through eyes and this member (210) may be positioned with the aid of tabs and guides. Rubber dust seals are also provided which are clamped in place using plates and wedge arrangements. These seals must be removed prior to removal of liner plates (111, 112).

  • Patent number: 6591976
    Abstract: A novel and advantageous carrier mechanism, primarily useful for raising roofing shingle bundles, automatically by control by the user to lift and carry one or more of the shingle bundles or other items. A frame carries a plurality of co-operating features, including a driving mechanism, an electric motor, a pair of chains and their sprockets, and when one of the shelf brackets gets to a top dead center position, the object falls in an orderly fashion due to a baffle, with succeeding shelf brackets sequentially reaching the top dead center position. The mechanism s is provided to have a sort of “stop and go” operativity, providing a safety control. Safety is further provided by a cam mechanism which assures only an upward direction when carrying a bundle. Safety is further achieved by an angle bar gutter guard, preventing undue bending, leakage, or other damage to the gutter.

  • Patent number: 6533109
    Abstract: An elongated bridge-like member which normally assumes an operative position in which it prevents access to a track for the advancement of finished or partly finished cigarette packs between two successive stations in a packing machine is designed to have its length reduced prior to being movable—without colliding with parts at the stations—from the operative position to an inoperative position in which the track and the cigarette packs in the track are accessible. To this end, the bridge-like member has two carriages each of which includes one of the two end portions of the fully extended bridge-like member; each carriage is movable toward the end portion forming part of the other carriage. A locking device must be disengaged in order to permit movement of the bridge-like member from the operative to the inoperative postion.
