Abstract:
The invention provides a curved belt support apparatus (300) that prevents a curved belt (200) from moving inward by supporting a thick part (220) of the curved belt that thickens in both vertical directions at the outer edge of the belt. An upper roller (370) is brought in contact with the upper inside surface (221) of the thick part (220), a lower guide roller (380) is brought in contact with the lower guide roller (380) is brought in contact with the lower inside surface (222) of the thick part (200), and the upper and lower guide rollers are elastically supported such that they can move up and down. When operated, the upper guide roller (370) and the lower guide roller (380) are moved diagonally upward and downward, respectively, in the direction of the radial inner edge of the curved belt so that the thick part (220) of the belt is released from the upper and lower guide rollers.
Abstract:
An improved method of transporting materials or products for chilling or freezing comprising the use of a multi-tiered, spiral path conveyor belt capable of tight radial turning in a restricted area to immerse the materials or products into a tank containing a cooling fluid and circulating the cooling fluid past the material or product is presented. The materials or products may or may not undergo chemical preparation prior to immersion, depending on the type of materials or products to be chilled or frozen. The cooling fluid, which can be food-grade solute, is circulated past the material at a substantially constant predetermined velocity and temperature to freeze the material or product. The cooling fluid is preferably between -20 degrees centigrade and -30 degrees centigrade, and the velocity of the cooling fluid past the material is about 35 liters per minute per foot of cooling fluid through an area not greater than about 24 inches wide and 48 inches deep. Alternatively, the speed of the multi-tiered, spiral path conveyor belt can be adjusted to increase or decrease the rate of immersion of the materials or products into the cooling fluid. All components of the multi-tiered, spiral path conveyor belt can be constructed of food-grade plastics.
Abstract:
The chain comprises a plurality of interconnected link assemblies. Each link assembly has a pin (2) extending laterally of the chain and supports a rotary roller (3) outboard the link assembly. A bearing member (4) is formed on a link plate (1) of the chain or on a cage (16) that, in use, engages at least part of an outer circumference of the rotary roller to provide a bearing surface.
Abstract:
A seamless conveyor belt for a powered belt (10) turn formed on a cone-shaped mandrel (35). One such belt is made by positioning fabric on a cone shaped mandrel surface (36) to form a frusto-conical fabric core (38), winding a cord (60) on the outer surface (40) of the fabric core to form a plurality of cord windings (64), impregnating the cord windings and fabric core with a polymer resin, allowing the resin to cure to form a composite belt structure of the resin-impregnated cord windings and fabric core, and removing the belt from the mandrel. Optional battens or profiles reinforce the belt laterally. The cord windings or fabric core can be omitted.
Abstract:
A belt (10) for use in a conveyor system has ribs (12, 14, 23, 24, 26, 30) to aid in the training of the belt. The invention comprises a belt (10) with a body (18) having an inner surface (16), an outer surface, and a first set of longitudinal ribs (12, 14, 23) disposed on the inner surface (16) of the belt. The ribs function to lessen the surface area of the belt contacting a roller (32) of the system during the training period. Accordingly, the new belt adheres to the rollers of the conveyor system less aggressively, reducing lateral coplanar forces having the potential to damage the belt and/or the conveyor system. The height of the ribs with respect to the body diminishes over time due to normal frictional wear during the use of the belt in the conveyor system. In some embodiments, the belt includes a second set of ribs (24, 26, 30) disposed on the outer surface (28) of the belt. The height of the second set of ribs with respect to the body also diminishes over time due to normal frictional wear during the use of the belt in the conveyor system. The sets of ribs may comprise two ribs (12, 14, 24, 26) running along the edges (20, 22) of the belt. A wider belt may require additional ribs (23, 30) located between the two edge ribs. The belt may be used in a system of rollers (32) and training guides (34). The training guides (34) function to maintain the alignment of the belt with respect to the rollers.
Abstract:
Method for chain drive, whereby the chain, such as a transmission chain, conveyor chain and/or like, is formed of several shaped pieces (1), that are connected to each other one after another at jointing points (N) by means of joint pins, and that is being driven by means of a wheel arrangement, that includes at least one chain wheel (7), such as a drive wheel, a turning wheel or the like. Particularly wearing of the chain, that is due to bending of the chain essentially along the longitudinal direction (p) of the joint pins, is being minimized by taking advantage of joint pins (x), the cross section of which changes in the longitudinal direction (p). The invention also relates to chain functioning according to the method.
Abstract:
The invention relates to a belt guide for short belt conveyors (1) in which an endless belt is passed over rollers (3, 4) at the ends of the conveyor. A plurality of glide strips (10) which extend generally in the direction of belt movement (7) beneath the upper run of the belt and over a stationary plane or surface (12). They are pivotal along the plane (12) about a respective pivot (11) in the proximity of the conveyor input end (8) and mutually connected for common angular movement around the pivots (11). The upper surface of respective glide strips (10) is proud of the common tangential plane of the end-rollers (3, 4) so that there can be generated between the glide strips (10) and the conveyor belt a contact pressure which is sufficiently great for the frictional force that acts laterall between the strips and the belt to enable lateral displacement of the belt in response to an angular change in the position of the glide strips (10).
Abstract:
A steep or vertical conveyor for bulk materials (13) has a driven conveyor belt (1) pressed by a pressing device against a fixed, non-resilient wall (3). The material to be conveyed (13) is loaded on the conveyor between the conveyor belt (1) and the wall (3). The wall (3) is designed as a sliding wall and consists of a non-resilient sliding metal sheet (3). The height of the sliding metal sheet (3) may be adjusted over the whole length of the conveyor path, so that various loading heights and conveyor paths are obtained. A gap is always present between the conveyor belt (1) and the sliding metal sheet (3). The height of the sliding metal sheet (3) may be adjusted in that the metal sheet is a steel strip whose bottom end is wound around a drum (18).
Abstract:
A conveyor belt or belting comprises a solid woven carcass impregnated and coated with rubber. The warp yarns (12, 13) are comprised of polyester filamentary yarns doubled with texturised polyester yarns. Where the solid woven carcass is woven as a four ply or more construction the inner warp yarns (13) travel along a straighter path than the two outermost warp yarns (12) such that the outermost warp yarns (12) create "pockets" at the surface of the carcass.
