  • Patent number: 9115802
    Abstract: A drive sprocket for driving a modular belt having a plurality of belt modules with intercalated link ends connected by transverse pivot members to form hinges. The belt modules may have transverse ribs. The drive sprocket is driven by a shaft. The drive sprocket has a central opening for receiving the shaft. The body has a plurality of teeth disposed in pairs along a periphery of the body. The body has a first opening formed between adjacent pairs of teeth and extending toward the center of the sprocket to provide access to the hinge area, when the belt engages with the sprocket, for application of cleaning fluid.

  • Patent number: 8544637
    Abstract: A continuous conveyor belt (1) has a transporting side and a driving side (31). Arranged on the driving side (31) are driving ribs (2), spaced evenly apart in the running direction (9) of the conveyor belt and running transversely to the running direction (9) of the conveyor belt. The driving ribs (2) have lateral guiding elements (21) for longitudinally guiding the conveyor belt (1) on teeth of a driving element. These lateral guiding elements (21) are formed in the manner of crests of a wave. This ensures good cleanability.

  • Patent number: 8276747
    Abstract: A modular conveying system with sprockets engaging the modules such that they do not cover any link gaps but are positioned between the link gaps. The module is characterized by link structures having link pairs that are spaced apart sufficiently at a distance to allow the sprockets to be located between the link pairs. Positioning the sprockets between the link pairs leaves the hinge gaps uncovered and thus allows free access to the hinge gap for cleaning.

  • Patent number: 7997404
    Abstract: A series of rows of belt modules wherein a first one of the rows may have a plurality of hinge elements along an end of the first row. A second one of the rows may have a plurality of hinge elements along an end of the second row. The plurality of hinge elements of the first row may be interleaved with the plurality of hinge elements of the second row. A pivot rod may extend through the plurality of hinge elements of both the first row and the second row so as to pivotally join the first row to the second row. A sphere may be supported from a first module of the first row and supported from a second module of the first row, so that the sphere resides between the first module and the second module and so that the sphere extends above the modules in order to allow an object, which is to be conveyed by the conveyor belt, to be supported on the sphere. The modules may be moved in a belt travel direction in order to convey the object from a first location to a second location.

  • Publication number: 20060237290
    Abstract: A belt module (10), modular belt assembly and method of configuring a modular belt to provide an edge portion for retaining a headed pivot rod (103). The edge portion has a blocking member (70) disposed in a slot (73) and movable between a first open position and a second closed position. In, the closed position, the blocking member extends into an edge portion pivot rod opening (51) to prevent the headed pivot rod from exiting the edge portion pivot rod opening. The edge portion pivot rod opening is larger than the first and second pivot rod openings in the first and second link ends of the belt module such that the pivot rod can only be removed in one direction.
