Abstract: A split sprocket for conveyor belts or chains comprises a first section and a second section that mates with the first section to form a sprocket with drive teeth distributed about the periphery and a central hub for retaining a shaft. The second section is inserted into a space in the first section and rotated into an engaged position to form a complete sprocket.

Abstract: A method for closing modular belts and a belt closer having two clamps for clamping to a side edge of a modular flat-top conveyor belt. A ratchet strap or other pulling tool is connected between the two clamps of the belt closer. Once the clamps are clamped to unconnected end sections of a belt, the ratchet strap is used to pull the two sections together so that they can be joined by a hinge rod to form an endless belt.

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: Metal-link conveyor belt modules and belts made of such modules. The belt modules have a crossbar. Links extend from opposite sides of the crossbar and terminate in loops. The links have regions of different widths tailored to various operational requirements.

Abstract: Apparatus and method for activating conveyor belt roller assemblies by lowering and extending wearstrips to selectively lower the conveyor belt to place the conveyor belt roller assemblies into contact with actuating rollers. A wearstrip module housing the wearstrips includes an upper support upon which the wearstrips are mounted that is longitudinally and vertically movable relative to a lower support fixed relative to the actuating rollers. Mounting brackets rotatably mount the lower support and actuating rollers in a fixed position and orientation.

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: Conveyor belt modules and a modular conveyor belt constructed of those modules. The belt modules comprise a plurality of thin metal links attached to a crossbar at spaced locations. The metal links extend along lines oblique to the length of the crossbar from a first loop to a second loop. Belt rows include one or more of the belt modules sandwiched between tension links. Hinge rods connect adjacent belt rows together through aligned first and second loops and first and second rod holes in the tension links of adjacent belt rows to form the conveyor belt. The links can be formed of bent wire or stamped and bent sheet metal. Intermediate portions of the links can be planar or curved.

Abstract: A conveyor component for use in a conveyor includes a flexible hub for mounting a shaft and a continuous rim connected to the flexible hub for contacting a conveyor belt. The flexible hub includes a peripheral gap that can be widened using an expansion tool to enlarge a shaft-receiving opening formed by the flexible hub. Positioning tabs on a radially inner surface of the flexible hub move into engagement with a groove on the shaft when the conveyor component is in a relaxed state and the peripheral gap is contracted and out of engagement with the groove when the peripheral gap is expanded, and the flexible hub is flexed.

Abstract: A stacked-package detection system for a matrix sorter detects stacked packages by comparing weight or dimension measurements on primary sorters from those measurements on secondary sorters. Weight or dimension increases for a package on a secondary sorter indicate a stack of packages. A recirculation system diverts packages identified on the secondary sorters as stacked packages back into bulk flow to be reprocessed by the primary or secondary sorters.

Abstract: A method for pulling a modular conveyor belt and a belt puller for performing the method. The belt puller has eyelets on one end that interleave with hinge elements on an end of a modular conveyor belt. A rod through the eyelets and the hinge elements connects the belt to the puller, which can then be used to pull the belt. Two ends of an unconnected belt can be pulled together by connecting a belt puller to each end, joining the belt pullers with a ratchet strap or other pulling tool, and tightening the strap to pull the ends together.

Abstract: A magnetic conveyor (30) comprising article-supporting movers (80) propelled by an array of stator elements (72) arranged in rows and columns. The movers include permanent magnets (82) whose magnetic fields interact with electromagnetic waves produced by the stator elements. Some of the stator elements produce electromagnetic waves that travel parallel to a conveying direction and others produce electromagnetic waves that can be controlled to travel in any direction. Movers are arranged in a formation of rows and columns in a staging area. An article (34) is transferred onto a group of movers in forward rows of the formation in the staging area. The group separates from the staging area as it conveys the article in the conveying direction. Stator elements are energized to replenish the staging area with movers to fill the gaps left by the article-conveying group of movers.

Abstract: A conveyor system includes a conveyor belt having a plurality of article-diverting conveyor belt rollers. An underlying drive roller assembly includes a plurality of pivotable rollers carriers, each having a freely rotatable drive roller that contacts the conveyor belt rollers from below. An actuator moves a movable orientation plate along an arc-shaped path to pivot the carriers and change the orientation of the drive rollers. The drive rollers may also move into and out of engagement with the conveyor belt rollers as their orientation changes. The movable orientation plate is sandwiched between upper and lower support plates to adjust the orientation of the drive rollers relative to the belt rollers.

Abstract: A sorting conveyor system sorting parcels into volume-adjustable containers with movable floors and an associated method for adjusting the depth of the container's interior volume. The containers are mounted on carts and have movable floors that are raised and lowered to decrease and increase the depth of the container's interior volume below an upper rim as a function of the load of parcels in the container.

Abstract: A conveyor belt module includes a laterally-extending protrusion to prevent misorientation of the module during assembly. In a proper orientation, the laterally-extending protrusion extends into a recess of an adjacent conveyor belt module, with clearance between the protrusion and the nadir of the recess. Reversal of the conveyor belt module prevents the conveyor belt module from fitting into a row of modules.

Abstract: A transfer system comprising a carrier attached by fastening structure to a linear-motor shuttle driven by a linear-motor stator along a track. Tray packs or other conveyed objects are transferred between the carriers and infeed and outfeed conveyors by the carriers at transfer segments as the carriers advance along the track.

Abstract: An edge module for a modular conveyor belt. The edge module includes a rod-retention plug that is pivotably mounted in a socket that opens onto the module's bottom. The plug has a bore that receives an axle in the socket on which the plug can be rotated. An arm attached to a main body of the plug by a living hinge allows the arm to flex from a relaxed state occluding a hinge-rod passageway at the belt's hinge joints to a flexed state allowing a hinge rod to be inserted into or removed from the passageway. Locking structure on the plug and in the socket engage to lock the plug in place. A sideguard mounted in the edge module is locked in place by locking structure in the edge module. Locking structure on both the sideguard and the plug engage to lock the sideguard and the plug in place.

Abstract: A dedicated access assembly for a conveyor belt forms a dedicated opening and closing point for the conveyor belt. The dedicated access assembly includes a female portion having one or more open hooks and a male portion including a hinge rod extending between linking elements. The open hook disengages from and engages the hinge rod to selectively open and close the conveyor belt. A latching mechanism can selectively lock the dedicated access assembly.

Abstract: A modular plastic conveyor belt constructed of injection-molded belt modules having narrowed portions either above or below rod holes in hinge elements. The narrowed portions are formed by a restricted-flow region in an injection-mold cavity that ensures that weld lines in the hinge elements are angled off the pull line of the conveyor belt.

Abstract: A hinged magnetic mover for conveying product comprises a plurality of hingedly connected modules including magnets. The magnets form an array of X magnets alternating with Y magnets. A carryway for the hinged magnetic mover forms a stator comprising XY coils with Hall sensors for interacting with the magnets to induce a motive force on the mover.

Abstract: A conveyor belt module (20) includes a movable hinge rod retainer (220) that can be opened and closed without tools. The movable hinge rod retainer facilitates opening and rejoining of the conveyor belt (100) at one or more dedicated locations. In a first position, the hinge rod retainer locks a hinge rod (130) withing a hinge rod passageway. A user can easily move the hinge rod retainer to a second position in which the hinge rod passageway is open to allow removal of the hinge rod.
