  • Patent number: 12679659
    Abstract: A modular belt constructed of belt-edge modules that include slide bodies that slide along recesses in base module bodies. Slide cam surfaces on the slide bodies' hinge elements interact with base cam surfaces on the base module bodies' hinge elements of adjacent belt rows to move the slide bodies laterally as the belt articulates and de-articulates at its hinge joints. Optional clamp jaws on the base module bodies and the slide bodies are opened and closed by the sliding action. A belt with clamp jaws can be used as a cover belt for a conveyor belt with sideguards.

  • Patent number: 12673827
    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.

  • Patent number: 12623853
    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.

  • Patent number: 12612258
    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.
