Abstract:
The crossover conveyor chain system includes a first conveyor chain (S1) and a second conveyor chain (S2) crossing the first conveyor chain (S1) to transfer the product from the first conveyor chain (S1) to the second conveyor chain (S2) while reorienting the product to a direction nearly perpendicular to that on the first conveyor chain (S1). The first conveyor chain (S1) is supported on an end bar (10) or a small-diameter sprocket, and the second conveyor chain (S2) is formed a plurality of chain unit pairs each including at least two types of chain units (A) different in length from each other and a coupling pin (B). Each of the chain units (A) has front convex portions (1) and front concave portions (3), disposed alternately at the front thereof, rear convex portions (2) and rear concave portions (4), disposed alternately at the back thereof, and a transfer overhanging portion (7) formed integrally at one lateral thereof. The transfer overhanging portion (7) has a beveled lower surface (8) formed on the lower side, at the free end, thereof and an inclined upper surface (9) formed on the upper side, at the free end, thereof. Because of this construction, the transfer overhanging portion (7) can be set short, and so it can be formed not easy to flex and break as well as to flex vertically, which assures to transfer the product stably and smoothly and prevent the load (weight) of the product from concentrating on a limited portion of the conveyor chain. Therefore, the crossover conveyor chain system is highly strong, rigid and durable, easy to be designed lightweight and compact, simple in construction, suitable for mass production, easy to assemble, easy to handle, and less expensive.
Abstract:
A durable reinforcing band for conveyer belts, wherein a reinforcing band (3) is formed by interweaving a number of hard cords (6) facing a direction orthogonal to the longitudinal direction and longitudinally spaced at predetermined intervals with a number of longitudinally directed warp yarns (7) in such a manner as to prevent longitudinal shift, the reinforcing band (3) being disposed on the upper or lower surface of a core (2) composed of canvas or the like and being then surrounded by rubber (5), thereby forming a belt (1), and wherein the transverse stiffness and shape retainability of the belt can be enhanced by arranging the hard cords in a direction orthogonal to the longitudinal direction of the belt, and moreover, the hard cords are prevented from shifting longitudinally of the belt; and a conveyer belt, particularly pipe conveyer belt, using the same.

A chain conveyor formed from a plurality of modules or links (1a, b, c) connected together by pins (2a, b) which are inserted through holes (4, 4A) present in said modules or links (1a, b, c) and are prevented from escaping by axially counteracting elements (5) mounted in seats (6) also present in said modules or links (1a, b, c), in which said axially counteracting elements (5) present a flexible tang (5c) which, when the axially counteracting element is mounted in the seat (6), intersects an end portion (4A) of the holes (4, 4A) through which the pin (2a, b, c) is inserted, to thus prevent said pin withdrawing from said holes (4, 4A), such withdrawal however being enabled by deflecting the flexible tang (5)
Abstract:
A belt assembly for a belt turn conveyor includes a belt with a plurality of longitudinal fibers generally aligned or oriented along the curved longitudinal axis of the belt. The belt may comprise a plurality of belt segments which are interconnected to form an endless belt, with each belt segment preferably including a plurality of longitudinal fibers aligned along the longitudinal axis of each respective belt segment. When interconnected, the longitudinal fibers of each belt segment generally align along the curved longitudinal axis of the belt. Alternately, the belt may be woven such that the longitudinal fibers are substantially aligned along the curved longitudinal axis of the curved belt. Thus, a belt assembly for a belt turn conveyor is provided that exhibits a more uniform stiffness along its length, which results in the belt assembly exhibiting reduced forces across its length thus increasing the belt's capacity and longevity.
