Abstract:
An intermediate drive for a conveyor system is disclosed. The drive includes at least one, and preferably a plurality of spaced parallel drive sprockets gang mounted on a common drive shaft. In the preferred embodiment, each sprocket engages a separate conveyor belt to drive it in the same direction in an endless path along a conveyor guide rail. Each guide rail includes a recessed portion that preferably matches the contour of the corresponding sprocket. By juxtaposing each sprocket in the recessed portion, engagement between each drive sprocket and the corresponding modular link belt is made. The drive may also be used along a curved section of the conveyor system, in which case the drive sprockets have different diameters for driving the belts at different speeds, and the contour of the recessed portions correspond to the adjacent drive sprocket.
Abstract:
A conveyor for possible use in transferring articles between two adjacent conveyors is disclosed. In one embodiment, the conveyor includes a pair of idler structures and a drive structure for collectively guiding and moving a conveyor belt or chain relative to a bed. At least one of the drive structure or idler structures is mounted or positioned so at to be capable of moving relative to the belt or chain to provide tensioning therefor. In another embodiment, a bed assembly including the chain or belt, the drive structure, and the idler structure is also substantially fully releasable from a corresponding base for servicing or clearing a jam. In either case, the conveyor may be driven using a slave drive associated with an adjacent conveyor.
Abstract:
A split housing for a sprocket in a conveyor system is disclosed. The sprocket includes a first, preferably upper portion that mates with a second, preferably lower portion to define a curved guide track for guiding a conveyor belt from a forward to a return run, or vice versa. The split nature of the housing allows for the removal of one portion, such as the upper portion, in a vertical direction without the need for moving the adjacent sprocket or guide rail. Hence, the other portion may remain attached to a stable structure used to support the conveyor system.

Abstract:
A split sprocket assembly, related apparatus, and a method of mounting a sprocket to a rotatable structure, such as a drive or idler drum, are disclosed. In one embodiment, the sprocket assembly is comprised of at least three sections or segments, each of which is secured to the adjacent section or segment by a fastener, such as a tangentially-extending bolt and nut combination. The sprocket assembly includes a plurality of receivers, each for receiving a key that corresponds to a keyway formed in the rotatable structure. In one embodiment, at least one of the keyways is truncated and, thus, extends only partially across the rotatable structure in the axial direction. A key substantially identical to the truncated keyway in length and width is placed therein, such that the sprocket is prevented from traveling or “walking” along the rotatable structure.
Abstract:
An apparatus for conveying one or more objects along a conveying path in a conveying direction includes an endless conveyor chain formed of modular links arranged in rows in a direction transverse to the conveying direction. The links include spaced outer side links forming a part of a conveying surface for the objects to be conveyed and intermediate links interconnected with side links by connector rods, the chain having at least a forward run for conveying one or more objects in the conveying direction. A driver is provided for driving the conveyor chain, and includes a first sprocket adapted for engaging at least one side link along at least one side of the chain, the first sprocket mounted for rotation about an axis generally orthogonal to the conveying direction and the transverse direction. The sprocket may comprise a split sprocket, and may be adapted for pivoting movement.
Abstract:
An improved conveyor chain formed from a plurality of modular links arranged in rows and each associated with at least two elongated transverse connectors is disclosed. In one embodiment, the connectors together create a substantially open, planar support surface intermediate of the links in each row. Each link in a first row includes apertures for receiving a first of the connectors extending through a slot in the links of an adjacent row, as well as a receiver having a closed end and an open end for receiving one end of a second one of the connectors. The chain with the connectors associated with each row is thus capable of side-flexing to negotiate curves or bends, as well as longitudinal compression/expansion, while at all times providing full and even article support.
Abstract:
A unitary modular link or link section for use in forming a rodless conveyor belt or a section thereof is provided. The link section includes a plurality of laterally-repeating link-shaped portions, each including an apex portion and a pair of leg portions. Each apex portion includes a receiver for receiving an integral first connector extending between the leg portions of a next-adjacent link or link section, preferably in snap-fit engagement, such that relative pivoting movement is established. A second integral connector maybe provided between the leg portion of each adjacent apex portion to create an engagement surface for a tooth of a drive or idler sprocket. The underside surface of each link section may also be specially contoured or curved to facilitate smooth passage over a guide structure.
