    Abstract: A modular conveyor belt (20) constructed of a series of rows (24, 25) of belt modules hingedly interlined by tapered oblong hinge pins (22) and suitable for following straight or curved conveyor paths. Aligned slots (30) formed in one set of hinge elements between successive rows are elongated in the direction of belt travel to allow the belt to fan out in turns. Fan-shaped apertures (38) formed in interleaved hinge elements of an adjacent row and aligned axially with the slots to admit a hinge pin (22) allow the belt to pivot at the hinge to articulate about a sprocket (181) or idler (186) or to enter and exit an incline. The oblong hinge pin has a first region at a first end (88) with a constant long axis to share the belt load among hinge elements encompassing the first region on straight runs. A second region of the hinge pin at an opposite second end (89) has a tapered oblong cross section, the long axis of which increases with distance from the second end to define a variable pitch and to spread the belt tension among the hinge elements at the outside of a turn encompassing the second region. Each belt row can be constructed of individual links stacked together on a support element (45) and retained by fasteners (52) or of integrally molded modules each comprising a transverse connecting member from which leading and trailing hinge elements extend. Accessory attachments, such as teeth (160) or sideguards (150), can be added to the belt. The belt can be driven by a cog, a roller chain, or other driving means driving lugs (172) extending from the bottom of the belt. The drive surfaces of the lugs can be obliquely arranged for better load sharing.

    Abstract: Un transportador en espiral que comprende una cinta transportadora y una torre de accionamiento que se extiende desde una parte inferior a una parte superior y que comprende una periferia exterior que rota alrededor de un eje vertical, y la torre de accionamiento comprende, además: una pluralidad de miembros de accionamiento paralelos (200) que se extienden en longitud desde la parte inferior hasta la parte superior de la torre de accionamiento en la periferia, estando configurados los citados miembros de accionamiento para aplicarse con dientes en el borde interior de la cinta transportadora; en el que cada uno de los miembros de accionamiento (200) incluye una cresta que se proyecta hacia fuera (202) que termina en un extremo de punta de entrada (208) en la parte inferior en una espiral ascendente y en la parte superior en una espiral descendente; y caracterizado en que cada uno de los miembros de accionamiento (200) incluye un miembro de alineación (212) dispuesto cerca del extremo de punta (208) para ayudar a alinear los dientes en el borde interior de la cinta transportadora con la cresta (202), en el que el miembro de alineación es un saliente ( 212) que se extiende radialmente hacia fuera desde el miembro de accionamiento (200) una distancia menor que la cresta (202).

    Abstract: The present invention relates generally to power-driven conveyors and more particularly to spiral conveyors in which a conveyor belt is positively driven in a helical path around a rotating drive tower. One aspect of the invention provides a spiral conveyor comprising: a drive tower extending from a bottom to a top and rotating about a vertical axis; a plurality of parallel drive members extending in length from the bottom to the top of the drive tower; wherein each of the drive members includes an outwardly projecting ridge whose distance from the vertical axis varies from the bottom to the top of the drive tower; wherein each drive member includes a lower segment at the bottom of the drive tower and wherein the ridge in the lower segment is tapered along a portion of its length. A further aspect of the invention provides a spiral conveyor comprising: a drive tower extending from a bottom to a top and rotating about a vertical axis; a plurality of parallel drive members extending in length from the bottom to the top of the drive tower; wherein each of the drive members includes an outwardly projecting ridge whose distance from the vertical axis varies from the bottom to the top of the drive tower; wherein the drive tower has an upper portion with a first diameter and a skirt portion tapered outwardly away from the vertical axis toward the bottom of the drive tower; and wherein the skirt portion includes a bottom portion with a second diameter greater than the first diameter and a tapered portion connecting the bottom portion to the upper portion.
