Abstract:
Disclosed is a novel transfer conveyor for transporting material from a feed point to an input section of a main conveyor. The transfer conveyor comprises a feed end, a discharge end, and a means for conveying material from the feed end to the discharge end. A connector is provided for detachably and rotatably connecting the transfer conveyor to the main conveyor such that the feed end of the transfer conveyor may be moved about the input section of the main conveyor while maintaining the flow of material from the discharge end of the transfer conveyor into an input section of the main conveyor. The transfer conveyor may be provided with a nozzle portion on the discharge end thereof to which the connector is attached. The transfer conveyor may also be provided with an undercarriage that is moveable between a compact storage position and a support position wherein the discharge end of the transfer conveyor is positioned at an elevated position relative to the feed end such that the transfer conveyor is operable as a stand alone conveyor. In addition, transfer conveyor may also include means for mounting the transfer conveyor on the main conveyor in a transport position wherein the transfer conveyor is suspended under the main conveyor.
Abstract:
A conveyor belt is mountable to a supporting frame. The belt is actuable in a first longitudinal direction for endless rotation of the belt relative to the frame. The belt includes a resilient endless core, and, mounted on the core, a contiguous endless outer surface and an opposite contiguous endless inner surface, where the outer and inner surfaces are disposed oppositely on the core. Generally laterally extending grooves are formed in the outer surface in a longitudinally spaced array along the belt.
Abstract:
A modular roller conveyor system in combination with a conveyor belt and load impact zone for loading material on the conveyor belt. The modular roller conveyor system includes an elongated support member extending transversely of a direction of conveyance for the conveyor belt, and a plurality of modular roller units located in end-to-end abutting engagement with each other on the support member. Each modular roller unit includes a roller support frame having an elongated base portion and upwardly extending end plates at opposing ends of the base portion supporting a shaft and a rotatable shell in supporting engagement with an underside of the conveyor belt. The base portion includes slots extending in the direction of elongation of the base portion, and the support member includes upwardly extending cooperating structures engaging within the slots whereby each modular roller unit is supported for sliding movement in a direction transverse to the direction of conveyance of the conveyor belt to provide a reduction of forces exerted on each modular roller unit through movement of the roller units in response to material impact loads on the conveyor belt.
Abstract:
A conveyor belt alignment device comprises an idler roller mounted relative to a conveyor belt, the idler roller having a first cylindrical portion extending over the conveyor belt proximate an edge thereof, and a second cylindrical portion abutting against an edge of the conveyor belt for preventing lateral movement of the conveyor belt relative thereto. The idler roller is biased toward the conveyor belt in a direction substantially perpendicular to a plane defined by an upper surface of the conveyor belt to allow debris to pass between the idler roller and the conveyor belt and thus reduce damage to the conveyor belt.
Abstract:
The present invention is directed towards a belt having a load-carrying surface located between transverse edges of the belt. The load-carrying surface is comprised of a plurality of ribs arranged in a plurality of overlapping columns extending along the length of the belt. Each rib has a leading edge and a trailing edge extending across the transverse width of the belt, and each rib is defined by a centerline located midway between the leading and trailing edge of the rib. The rib centerline has a non-linear configuration over a majority of the belt's useful lifetime.
Abstract:
A first modular unit (1) for the fabrication of conveyors (2), said first modular unit (1) comprising an upper surface (3) and a lower surface (4) and means (5) along at least one, preferably two long sides (13) lying diametrically opposite each other, for pivotal hinging of the first modular unit (1) to a second modular unit (6), and where extending from the upper surface (3) said first modular unit (1) comprises a flat carrier (7) with a front surface (8) and a rear surface (9), an upper concluding end (10) and two side edges (11) lying opposite each other, the middle/center plane (12) of said carrier (7) standing substantially at right angles to the upper surface (3) and extending parallel with the long sides (13). The front surface (8) and the rear surface (9) of the carrier each comprise at least one pin (14) extending from the side edges, a first surface (15) of said pins (14) facing towards the surface from which they extend and being flat parallel with this surface, and where the distance of the first surface (15) of the pins (14) to the middle/center plane (12) of the carrier (7) is at a maximum twice the distance between the middle/center plane of the carrier and the surface from which the pin (14) extends. The carriers lock tightly against each other, so that these withstand even great and uneven loads in such a manner that in certain areas greater weight and lesser weight can be applied to the carriers without this causing the carriers to separate from each other, and thus give rise to the possibility for the material which is to be conveyed to escape between possible cracks.
Abstract:
A tube conveyor, in particular a tube conveyor in which an endlessly revolving conveying belt is guided at least partly in the interior of carrier rolls (5) which are attached in a ring-shaped manner and whose axes extend substantially transversally to the direction of conveyance, and is substantially shaped into a tube, with the return of the conveying belt (3) being performed outside of the loaded strand shaped into a tube. In order to provide a tube conveyor which does not require any additional external supporting rolls for the return of the unloaded strand and thus both simplifies the installation of such a tube conveyor and reduces its noise production during operation, the return of the unloaded strand (9) of the conveying belt (3) is performed while resting on the upper carrier rolls (5) which are arranged in a ring-shaped manner.
Abstract:
The invention concerns a conveyor belt (1) operating as a deep semicircular trough provided with a covering belt (2), characterised in that the covering belt (2) is planar in inoperative state, except for its continuous sealing loops (8) and has a width (a) linked to the length (L) of the trough-shaped conveyor belt (1), at the angle (5) formed by the flexible covering belt (2), relative to the horizontal and to the length (b) of the continuous scaling loop (8), by the relationship anullL.cosnullnull2b, and a sealing device (5) is formed by said longitudinal loop (8), being urged to enclose, by automatic engagement, each of the longitudinal ends (6) of said conveyor belt (1), and the disengagement, in the proximity of the unloading zone (Zd) is obtained by simple release, under the effect of the opening of the trough angle (null) and the separation force between said belts (1, 2) without the intervention of any mechanical means.
Abstract:
An elongatable conveyor belt capable of traversing horizontal curves during its conveying run while still allowing for retention of the material to be conveyed thereon, the conveying belt being made of a stretchable or elongatable elastomeric material and including an upper layer of transverse reinforcing cords and a substantially heavier lower layer of transverse reinforcing cords disposed at opposing angles relative to the transverse axis of the conveyor belt. The belt also includes an internal stretch limiter such as an angularly woven fabric in the central region of the belt.
Abstract:
A conveyor belt that uses cleats to more effectively transfer materials through a curvilinear structure into a deposit receptacle. The cleats are either in the form of a notched cleat or slit cleat. In both forms, the cleat is adaptable to conforming from a flat conveyor belt to a curved conveyor belt within the curvilinear structure. The resulting cleat on the conveyor belt provides increased support for the prevention of backflow of materials during transportation of the materials through the curvilinear structure.
