Abstract

A modular metal-wire conveyor belt constructed of belt rows having an interior article-supporting wire-mesh section flanked by tension links at opposite side edges. Hinge rods through the article-supporting sections and the tension links in adjacent belt rows join adjacent modules at hinge joints into an endless belt loop. Some of the hinge rods have blocking structure at the inner sides of the tension links to maintain the belt's width constant. Other hinge rods are devoid of blocking structure and have rod caps on one end that can be removed to allow the rod to be pulled out of the hinge joint to open the belt for servicing. The article-supporting wire-mesh section can define a flat or a curved top.

Abstract

A system and method for detecting disengagement of a modular articulating conveyor belt from a toothed pulley with a laser beam. A laser transmitter and a laser detector are positioned at opposite sides of the modular conveyor belt wrapped around a toothed pulley. The laser beam is directed from the laser transmitter to the laser detector along a line that is intermittently intersected by radially outer structure on the belt as it advances fully engaged with the pulley. When the belt stretches with wear or when debris is trapped between the belt and the pulley, the belt starts to ride higher on the pulley in position to block the laser beam for longer time periods indicating disengagement of the belt from the pulley.

Abstract

Exemplary embodiments provide a sorting system using the principles of linear motors to move a magnetized mat in multiple directions. The sorting system uses a series of stator coils in particular patterns to direct the magnetized mat along predefined looping pathways such that the magnetized mat can move articles in a desired direction. Embodiments include the use of multiple magnetized mats to improve package sorting rates. The magnetized mat is comprised of a plurality of magnetized and non-magnetized tiles which are connected using flexible tabs that form a living hinge. The living hinge flexes and allows the mat to travel along the predefined looping pathways. The sorting system may be used as a node in a larger grid sorting system and may be connected to conveyors, chutes, or other means for moving articles.

Abstract

A closed-loop vacuum conveyor controlling the pressure in a plenum. Pressure sensors in the plenum send pressure signals to a processor that controls the speed of a blower motor sucking air from the plenum and through openings in a foraminous conveyor belt against which conveyed aluminum cans are held by air pressure. The processor controls the blower speed with a variable-frequency drive to adjust the pressure in the plenum to accommodate a varying product density or the shape, size, or weight of conveyed products on the outer surface of the conveyor belt. The plenum may be divided into separate chambers by partitions or adjustable dampers. The pressure in the chambers can be controlled by adjusting each chamber's blower speed or the opening of its dampers.

Abstract

A conveying system (100) employs independently controlled flights (160). The flights are controlled separately from a conveying surface using a linear transport system. The linear transport system allow the position of the flights to be controlled based on a parameter, such as the length of a conveyed object. The flights are pivotally mounted to a mover of the linear transport system and can pivot relative to the conveying surface to allow the flights to fit in a space between an end of carryway and a receptacle.

Abstract

A shrimp processing system conveys raw peeled shrimps to an imaging chamber in which shrimp bits and shrimps with residual shell are detected and diverted from the stream of acceptable shrimps allowed to pass on to downstream processing. An ultraviolet (UV) light source in the imaging chamber is constantly on. A visual inspection system takes images of the passing stream of shrimp when a white-light source is turned on to illuminate an exposure region to detect bits, clumps of shrimps, and acceptable individual shrimps. The visual inspection system takes images of the passing stream when the white-light source is turned off and the exposure region is subjected only to ultraviolet radiation. The visual inspection system detects shrimps with residual shell in the UV images. Shrimp bits and shrimps with residual shell are diverted from the stream of shrimps by air-jet nozzles to corresponding reject destinations.

Abstract

Retainer rings for locking in an N-sided shaft to restrict axial movement of components sandwiched between them. The retainer rings have inner edges bounding a central bore. The inner edges are defined by a series of N arcs whose distance from the bore's center decreases gradually along the inner edge from a first end to a second end of each arc. The rings are slid on to the shaft with the corners of the shaft aligned with the first ends of the arcs. Then the rings are rotated on the shafts toward the second ends of the arcs until the corners of the shafts jam against the inner edges. A special spanner wrench can be used to tighten and loosen the rings on the shaft.

Abstract

A continuous product-processing apparatus having a conveyor capable of repositioning product and cleaning itself of debris and a method for its operation. The apparatus includes a conveyor that transports products atop a conveyor belt along a carryway to a processing chamber. Upper and lower diverting rollers guide the belt along an S-shaped product-repositioning path segment of the carryway. The diverting rollers are rotated at a speed normally greater than the speed of the conveyor belt to cause the belt to slip on the roller's periphery, which effects a scraping action against the conveying side of the belt to dislodge debris from the belt and the rollers. One-way ratcheting drives or belt restricters positioned on the product-positioning path segment to limit belt excursion are used to prevent the belt from building up along the carryway and tightening in the lower return.

Abstract

An integral weighing and sorting system that weighs articles on a roller belt and selectively actuates or deactuates belt rollers to divert selected articles. After an article is weighed on the roller belt, its weight is compared to a predetermined weight range. Out-of-range articles are directed to exit the belt via a different route from that of in-range articles by actuating the rollers to rotate in a direction transverse to the travel direction in a roller-actuation zone.
