    Abstract: A belt conveyor for a road-finishing machine or a charger. The belt conveyor includes a conveyor belt in which a displaceably mounted support element abuts the conveyor belt, and a first and a second piston cylinder unit operate to displace the support element. The first and the second hydraulic piston cylinder units can be pressurised independently of each other in order to move the support element into a desired inclined position. If the conveyor belt of the belt conveyor runs laterally away from the support element, the out-of-true running of the conveyor belt can be counteracted by an inclined position of the support element which moves the conveyor belt back into its original position.

    Abstract: A conveyor system which has a continuous path conveyor is to be used for transporting and accumulating excessive loads. The conveyor may be formed of a continuous loop of chain elements. The conveyor path consists of two or more product carrying sections and corresponding offset return path sections. A product carrying section of the conveyor wraps around power driven sprockets where it is fed into and becomes a return path section. From there the path is guided over and aligned with free turning tail sprockets, where it is returned as a product carrying section. This section is then fed onto second drive sprockets, powered by another power means, where it again becomes a return path section, guided over tail sprockets and returned as a product carrying section. In this manner, the load of the conveyor chain is relieved at each drive sprocket assembly, thereby increasing the available working distance of the system.

  • Patent number: 6145653
    Abstract: A conveyor system comprises a pair of side-by-side conveyors adapted to move articles such as baggage or cargo in opposite directions simultaneously, preferably at the same elevation, and linked together by an endless belt. The endless belt is directed from the exit of one conveyor to the entrance of the other conveyor and from the exit of the other conveyor to the entrance of the one conveyor via a pair of conveyor twist assemblies which maintain the baggage carrying surface in an upward orientation on both conveyors. The twist assemblies can employ vertical or horizontal rolls to attain the direction change of the endless belt. Staggered idler rolls can be arranged beneath the two conveyors for belt support and reduction of vibration caused by belt travel. The side-by-side conveyor system is particularly useful in multiple stacked arrangements in tunnels for airports.

  • Patent number: 6021889
    Abstract: A conveyor for an endless, closed-loop conveyor belt (1), which is flexible transverse to its extension, has a guide (11) keeping conveyor belt on a substantially rectilinear main path (3) and on a generally perpendicular branch. A branch device (9) is movable along the main path. There the belt takes two branch paths (19, 20), both parallel with a branch line (26) which is generally transverse to the main path. The branch device (9) comprises two first deflection rollers (14, 23), which are offset in opposite directions laterally from the main path (3). The axes of the two deflection rollers are each perpendicular to a respective deflection plane. Each deflection plance passes through the center of the respective deflection rollers and intersects the main path and the respective branch paths (19, 20) at respective distances from the deflection rollers.

  • Patent number: 5743379
    Abstract: A feed/discharge insert for transporting goods at an acute angle with respect to a main conveyor belt. The insert includes an endless loop conveyor belt having an upper segment and a lower segment. Two rigid deflection bars are positioned one above the other parallel to the main conveyor belt. The two bare are solid with a polygonal, or preferably hexagonal, cross-sections. The upper and lower segments are guided and deflected about the two rigid bars. The endless loop conveyor belt is looped around a cylindrical drive drum of a belt drive. The endless loop conveyor belt contacts the drive drum about at least 180.degree. of its circumference. An adjustable deflection roller is used to vary the degree of contact between the endless loop conveyor belt and the drive drum. The invention also comprises a central station for limiting the lateral run-off of the conveyor belt.

  • Patent number: 5520824
    Abstract: The solid content and liquid content in a solid-liquid substance can be separated continuously at a high solid-liquid separation ratio by: causing a looped filter cloth member to travel, the filter cloth member being wound at least once around a wringing roller, and having a twisted portion at which the filter cloth member is twisted at least once and wound around the wringing roller; inducing a primary rotary motion of the wringing roller in a direction in which the filter cloth member travels; inducing secondary rotary motion of the wringing roller in a direction in which the filter cloth member is twisted upstream with respect to the wringing roller; and supplying a solid-liquid substance to an upstream portion of the filter cloth member with respect to the wringing roller.

  • Patent number: 5431289
    Abstract: A conveyor system for transporting and aligning articles to be sorted in an automated bulk processing system is disclosed. The conveyor comprises one or more product-carrying lanes, each lane comprising two side belts separated by a central product-carrying belt. Each of the side belts is raised with respect to the product-carrying belt, thereby guiding articles on to the product-carrying belt. In a preferred embodiment, the product-carrying belt has two product-carrying surfaces and is provided with a 180.degree. lengthwise twist whereby the product-carrying surfaces are alternately presented on the upper surface of the conveyor system for each complete belt travel cycle. The 180.degree. lengthwise twist is maintained in position by a belt guide or comb located on the underside of the conveyor system.

  • Patent number: 5421449
    Abstract: In an angle station for lateral angular displacement of an endless conveyor belt in a conveyor system, the angle station comprises a belt guide in the form of a plurality of large diameter guide rollers mounted in support brackets on a support structure with the rollers substantially clear of the support structure. The guide rollers are generally elongate and arranged substantially normal to a substantially helical pathway for the belt around the belt guide. The guide rollers are disposed in axially and laterally, closely spaced relation, so as to define a generally continuous support for a conveyor belt in use of the angle station, which support is substantially non-angular in cross-section along the helical pathway. A roller support bracket is provided for use in the angle station as well as a guide roller unit including a guide roller mounted in such bracket.
