    Abstract: A belt conveyor plant for conveying bulk material outdoors and in particular on hilly terrain comprises supporting and locating systems 15,16 for the load section 5 and the return section 6 of its conveyor belt 4, which under omission of a supporting frame extending uninterruptedly between the two terminal stations 2, 3 of the belt conveyor plant are in each case carried by a bearer 14 anchored separately in the soil 7. The conveyor belt 4 sags freely between the bearers 14 arranged with greater mutual spacing of at least 5 meters as in the case of a cableway. Since it is impossible in such case to guide the conveyor belt 4 formed into trough shape, use is made of a so-called corrugated edge belt, i.e. a conveyor belt 4 having a transversely stable belt element 20, whereof the carrying side has installed on it two longitudinally continuous undulant edge strips 21 (FIG. 2).

  • Patent number: 4674627
    Abstract: An easily-cleaned, rubberized conveyor assembly especially adapted for conveying granular or semi-fluid material. The present invention is particularly concerned with conveying food materials where cleaning and sanitary conditions are important. The invention is also particularly described with regard to a conveyor for the bottom of a holding or surge bin, but has other applications. In the invention, upright side guards along opposite sides of a continuous rubberized belt separate the belt into a central load-carrying portion and outer edge aligned portions. Connections connect the edge aligned portions to supporting girts beneath the belt, the girts in turn being attached to endless conveyor chains on opposite sides of the belt. Preferably, the side guards are rubberized elements vulcanized to the belt surface, thereby providing an assembly having a load-carrying area free of cracks or crevices.

  • Patent number: 4667812
    Abstract: Apparatus and a method of protecting the lateral edges of a conveyor belt. A resilient tubular member having a longitudinal slit therein is in resiliently maintained contact with the belt adjacent lateral edges. The resilient member may have portions of its inner surface spaced from the belt edge portions so as to define a number of cushioning air spaces therebetween. The resilient members are preferably of generally circular cross sectional configuration in unexpanded condition and are generally coextensive with the belt. The belt may have recesses for receipt of the slit ends of the tubular resilient member. The method may involve providing an elongated tubular resilient member which is slit longitudinally and circumferentially expanded so as to permit it to receive a lateral edge of the belt. The interengagement may be maintained through resiliently maintained contact alone or by additional means for securing such contact.

  • Patent number: 4515265
    Abstract: A belt conveyer and a conveying system using a belt conveyer. The system is designed to convey articles around curves and between vertically and horizontally spaced locations. The belt used in the system has a central substantially inextensible flexible spine and an upper load carrying portion supported by the spine. The load carrying portion has a plurality of ribs and a plurality of pleats interposed between the ribs. The ribs provide rigidity for the belt and limit movement of articles with respect to the belt, while the pleats provide longitudinal extension and contraction of side edges when the belt is following a curved path. The distance between top edges of the pleats and top edges of the ribs increases from outer edges of the belt towards the center so that top edges of the pleats are generally V shaped and conveyed articles and juices and liquids exuded from the conveyed articles tend to be conveyed in a central region of the belt.

  • Patent number: 4489825
    Abstract: A fluid levitated generally convex support member particularly useful in supporting a pallet, plate or belt such that the pallet, plate or belt load may be moved in an air powered track system, the system including at least one concave track with means for supporting and guiding the convex member and the pallet, plate or belt thereabove on a thin film of pressurized air jetting from nozzles in the track. The support member includes a generally tubular, flexible and partly deformable outer member and means for internally stressing the outer member so that under load there will be controlled deformation thereof. The deformed member will be closely complementary to the track surface to maximize load carrying capacity while minimizing fluid support power requirements and the detrimental effect of track deformities.

  • Patent number: 4410082
    Abstract: A conveyor belt of stretchable elastomeric material reinforced by layers of cords which permit an initial stretching of the belt at installation of at least 3 percent. Reinforcing cords are positioned in the belt elastomeric material to generate transverse forces during stretching of the belt which results in the interaction of the material of the belt with the cords. This interaction causes the edge portions of the belt to curl upwardly and form load-retaining walls at the edges. The belt may have a bottom stretchable portion which is reinforced to resist outside transverse forces resulting from the passage of the belt around a curve. A top stretchable portion of the belt has edge portions which bend upwardly to form the load-retaining walls. The edge portions of the belt may curl sufficiently to bring the edges together and they may be connected for enclosing the load on the belt surface.

  • Patent number: 4387801
    Abstract: An improved endless flexible conveying element is set forth. The flexible conveying element is of the type adapted to be mounted on a carrier and to conform with a generally curvilinear endless path for orbital traverse of such endless path. The conveying element has an elongated resiliently deformable portion which includes a longitudinally extending portion located laterally intermediate the longitudinal extending side portions thereof. The resiliently deformable portion of said conveying element laterally flexes to permit the belt to follow laterally curvilinear portions of the endless path in an upright position. The resiliently deformable portion has a tendency to spontaneously assume a natural form thereof, which is configured such that the resiliently deformable portion, when mounted on the carrier, is deformed from its natural form in a manner to provide in the side portions a condition of relative longitudinal tension with respect to the central portion.

  • Patent number: 4321996
    Abstract: The cleated belt forage conveyor of the invention is directed to a forage belt conveyor in which the belt in service is protected against side discharge of conveyed forage by upstanding and intermittent central cleats and outwardly spaced side cleats. Sealing strips extend above the belt in the spaces between the respective central and side cleats to limit outward movement of the bulk of the forage and an edging extends on each side of the belt to prevent spillover. In the event of some side discharge from the belt to the inside of the lower reach of the belt, a plow overlying the inside of the lower reach of the belt directs the forage for discharge to vibrating deflector plates which deflect the forage to the bottom of the housing of the conveyor to be carried by the cleats to the input side of the conveyor and around the idler pulley for reconveyance.

  • Patent number: 4205745
    Abstract: A flexible belt trough type conveyor is directed over a hump having an upwardly angling inclined side defined by belt supporting rails, then over a sprocket or similar rolling support device, and down the declined side of the hump on further rails. At the apex of the hump the belt is tensioned sufficiently to stretch the trough structures and partially or entirely flatten them, creating a loading station for granular materials such as explosives. When the belt has traveled over the apex, the tension decreases and the trough structure returns and automatically separates the granular material into discrete load units separated by the raised edges of the troughs.

  • Patent number: 4061223
    Abstract: A stretchable U-shaped conveyor belt with reinforcing members extending transversely of the belt and spaced apart longitudinally of the belt. Elastic stretchable material between the reinforcing members permits prestretching the belt so that the edges remain in tension when the belt passes around curves and thereby maintains the molded shape of the belt in horizontal and vertical curves. The conveyor belt is driven by a power belt and guided by guide rollers. The power belt and conveyor belt are carried by support rollers mounted on frames at spaced-apart positions along the belt path. The frames are fastened to a resilient, flexible spine member which provides for positioning of the frames around vertical and horizontal curves. The U-shaped cross section of the belt is also maintained by U-shaped reinforcing members of high modulus material which are positioned in two spaced layers within the molded body of the belt.
