Abstract:
A support structure for the return section of at least one conveyor, comprising including serpentine slat elements, support members for supporting said serpentine elements, and transverse members to which the support members are coupled, each slat element (1) being supported independently of the others by its own independent support members (2, 3); the support members (2, 3) comprise, on their lower edge, means (5, 5A) for their snap-coupling to the transverse members (6); the snap-coupling means being formed in such a manner as to enable the support members to be coupled by pressing them onto the transverse members downwards from above.
Abstract:
A flight module for use in a modular conveying belt for holding material on a moving belt. The module includes an intermediate portion having an upstanding wall that extends therefrom. The upstanding wall is corrugated in a direction transverse to the direction of belt travel. A first plurality of link ends extend outwardly from the intermediate portion and have openings defined therein that are transverse to the direction of belt travel. A second plurality of link ends extend outwardly from the intermediate portion in a direction opposite to the first plurality of link ends. The second plurality of link ends also have openings defined therein that are transverse to the direction of belt travel. The link ends are arranged such that the openings in respective link ends are capable of aligning when a pair of adjacent belt modules are juxtaposed. A pivot rod journaled in the aligned apertures of the side-by-side and end-to-end connected modules forms a hinge between adjacent rows. Rows of belt modules are connected together to form an endless conveyor belt capable of articulating about a drive sprocket.
Abstract:
A belt conveyor comprises a frame wherein at least two support rolls for supporting a laterally curved endless conveyor belt are disposed. The laterally curved endless conveyor belt carries on at least one of its surfaces a guiding bead disposed at or adjacent the outer peripheral edge thereof. Furthermore the belt conveyor comprises one or more bearing rolls for bearing the guiding bead. The guiding bead is a coextruded layered bead comprising a base layer of a base layer material which is fastened to the conveyor belt and a top layer of a top layer material which is flexible and wear resistant. Preferably the base layer is thermoplastically bonded to a top cover of the conveyor belt. If necessary the base layer is melted into a supporting bottom fabric of the conveyor belt. The top layer material comprises preferably a thermoplastic rubber or copolymer.
Abstract:
Endless belts having driving surfaces comprising a high temperature flexible thermoplastic composite. More particularly, an endless toothed belt having a high temperature-, abrasion- and noise resistant cover element, and which comprises from about 60 percent to about 100 percent by weight of the composite of a high temperature flexible thermoplastic material and from about 0 percent to about 40 percent by weight of the composite of a frictional modifier system, and methods for constructing such belts. Such belts include elastomeric body portions which may preferably be formed from suitable polyurethane materials.
Abstract:
An improved conveyor belt is provided including an overlay element with a variable loop count over at least a portion of a transverse width of the belt, and preferably with a variable loop count from one side edge of the conveyor belt to the other side of the conveyor belt, thereby minimizing the frictional contact between the overlay elements and minimizing the excess loop density on the side of the belt defining the inner radius of the turn. The conveyor belt includes a plurality of overlay elements, each of the overlay elements including a plurality of linking bends, and a plurality of transverse rods extending laterally across the conveyor belt. Each of the overlay elements are positioned relative to one another such that their linking bends are intermeshed with linking bends of immediately adjacent overlay elements and the intermeshed linking bends receive one of the transverse rods thereby operatively connecting the adjacent overlay elements. The plurality of linking bends on each of the overlay elements are positioned in a successive manner, extending from the inside edge to the opposite side of the conveyor, so that the distance between successive linking bends is greater than the distance between prior successive linking bends. This design increases the durability of the conveyor belt and the reliability of the conveyor system and improves the performance of processing systems while reducing the cost of the belt.
Abstract:
Drive and related travel tension is decreased at selected locations in special purpose travel paths for woven-wire conveyor belts enabling decrease in tensile strength requirements of metal wire components as assembled into a woven-wire belt. Connector rod configurations with varying depth seats, at selected locations for individual helically-wound loops of interacting spiral wires, provide for expansion of belt length at selected locations where needed to decrease or eliminate metal wire component strain. In unitary vertically-oriented lateral edge portions of an assembled belt during endless-belt travel about cylindrical configuration support rolls, travel tension is decreased by providing for added belt length of such unitary vertically-oriented lateral edge means as used for confining articles being conveyed; and, to provide more efficient and effective application of dynamic frictional drive forces along the length direction of travel of an elongated assembled belt in a travel path which is laterally-curved in relation to such length direction while maintaining a substantially-horizontal conveyance surface.
Abstract:
A conventional chain capable of reserving lubricating oil is complex in shape and expensive since each chain plate is formed with countersunk recesses and through-openings. Since the recesses are formed in an overlap region, the chain tends to rattle, producing noise. In the present invention according to which lubricating oil is fed toward a connecting pin, the lubricating oil is transferred to the connecting pin to effect intended lubrication. Part of the lubricating oil thus fed adheres to the recessed surfaces of the recesses and is prevented from immediately flowing down by viscous friction resistance and surface tension in the recessed surfaces. Thus, the oil is held in its adhering state. The lubricating oil gradually flows down to be used for lubrication as the chain moves. Thereby, after the chain has passed by an oil feeder, the connecting pin of the chain stays in such a state that oil is fed continuously for a long time.
Abstract:
An improved bucket conveyor chain that uses a series of plate type lines 3 connected together at adjacent ends by a bars 5 and 9. Ropes 11 are connected to the bars 5 and 9 to protect the chain from breaking in half in case of damage. The bars 5 and 9 are sectionalized and overlapped thereby providing easier maintenance.
Abstract:
A conveyor belt is described having a woven fabric backing which includes staple fiber yarn and includes a twill weave with an inclination angle of 10.degree. to 70.degree. relative to the moving direction of the conveyor belt, and in which adjacent yarns have the same direction of lay. In the woven fabric backing the staple fiber yarn is provided as warp yarn, each of which has the same direction of lay in its longitudinal direction, and adjacent yarns of which are alternately S and Z twisted. Additionally, elements which support the tensile forces are arranged in the conveyor belt, the elements being arranged in a woven fabric or being sheathed as threads by staple fibers. Since the staple fiber yarn of the warp of the woven fabric backing extends diagonally over the entire width of the conveyor belt, an endless support results even when the belt runs over an edge, and an absolutely uniform vibration-free conveyor belt movement having a low noise level is achieved even when the belt passes over an edge.
