  • Patent number: 10029862
    Abstract: A conveying system includes a first belt conveyor; a second belt conveyor; a workpiece guide that includes guide paths that receive workpieces that have fallen from a downstream end portion of the first belt conveyor one by one and then guide the workpieces to an upstream end portion of the second belt conveyor; a rotary mechanism that displaces the downstream end portion along a substantially arc-shaped trajectory to distribute the workpieces that have fallen from the downstream end portion into the guide paths; a first sensor that detects first information that represents that one of the workpieces has fallen from the downstream end portion; and a controlling device that controls an operation of the rotary mechanism. The controlling device controls the rotary mechanism by transmitting an operation command to the displacement mechanism to intermittently displace the downstream end portion by a predetermined distance in response to first information.

  • Patent number: 8322379
    Abstract: A diverter valve for a material transportation system includes a front cover defining an inlet passage, a rear cover defining first and second outlet passages, a casing connected to the front and rear covers and an inner tube arranged in the casing. The inner tube rotates to selectively align an outlet thereof with the first or second outlet passage. An inlet of the inner tube aligns with the inlet passage and the first outlet passage to thereby provide a straight passage through the diverter valve which aligns with a straight passage through the transportation system. When the inlet of the inner tube aligns with the second outlet passage, it provides a straight, branched passage through the diverter valve to, e.g., a receiving container. The inner tube is rotated between its alignment with the first or second outlet passage by an actuator.

With the cessation of power to the drive system a pivotal arm swings into engagement with a radial stop on the rotatable plate to lock the rotatable plate from further forward rotation while the drive system which is powered through a gear reduction drive functions as brake to prevent back rotation of the rotatable plate once the power is shut off to the motor.

  • Patent number: 6030152
    Abstract: A pneumatic switch having a wiper seal to inhibit material from escaping from a pneumatic conveying line during a switching process and to maintain the pneumatic conveying line in a closed condition to prevent contamination of the contents of the pneumatic conveying line and an inflatable seal to seal around a pneumatic conveying line with the pneumatic switch including a movable housing that is moveable with respect to a second pneumatic conveying line. The movable housing bearing is carried by a movable plate that allows one to position or reposition the pneumatic conveying line with respect to another conveying line to thereby divert material from one conveying line to another conveying line while an inflatable seal allows one to seal and reseal around the pneumatic conveying line.

  • Patent number: 5931611
    Abstract: A ball cleaning system incorporates an object converger and diverter. The converger accepts objects from a plurality of inputs at a housing and uses a flexible tube to selectively connect each input to a single output. A motor, elongated member, and actuator move the flexible tube between inputs. The diverter includes a Y-shaped assembly, a solenoid, and a gate wherein the solenoid selectively moves the gate across the Y-shaped assembly so that objects passing through the Y-shaped assembly are directed down different branches of the Y. The actuator is a linear actuator.

  • Patent number: 5842818
    Abstract: A single-to-multiple line conveying system for conveying unstable articles, such as plastic bottles, having a neck ring. The unstable articles are neck ring supported and are conveyed in single file along a first path established by a first guide unit to second paths established by a plurality of second guide units through a third path established by a third guide unit having a displaceable section to align the third path with successive ones of the second paths by an electric motor actuated in response to an article counter. The unstable articles are air conveyed along the first and second paths with continuous movement of the unstable articles along the third path being effected by a continuously rotating star wheel that spaces the unstable articles and urges the unstable articles toward the displaceable section that includes a mechanical unit, having a continuously moving chain with article engaging finger units thereon, and an air unit for urging the unstable articles from the third path.

  • Patent number: 5810516
    Abstract: A conveyor system for conveying an article has an upper portion and a lower portion below the upper portion. The conveyor system comprises a guide mechanism configured for engaging the upper portion of the article in a manner so that the article is suspended from the guide mechanism. The guide mechanism is further configured for guiding the article in its suspended orientation along a conveyor pathway defined by the guide mechanism, the conveyor pathway having a lateral curve. The conveyor system further includes at least one air nozzle for connection to a source of pressurized air. The air nozzle is oriented for directing a stream of air in a direction generally adjacent the lateral curve and in a manner such that the stream of air blows against the lower portion of the article when the article is moving along the lateral curve of the conveyor pathway to counter inertial forces which tend to cause the article to deviate from the conveyor pathway.

  • Patent number: 5556236
    Abstract: A pneumatic filter transport system has a gate (18) in a section of conveying duct (2), which gate and is openable in response to signals indicating a filter rod jam in a receiver unit (15) connected to the duct. Once opened, the gate allows remaining filters in the duct to be directed to a dump (30): this reduces the risk of a receiver jam developing into a line jam (which is more difficult to clear). The gate may be provided in a curved section of duct just upstream of the receiver. The duct may incorporate a longitudinally-extending partition (60), which allows removal from the duct of loose material (e.g., carbon granules) which has become separated from the conveyed filters. The duct may have longitudinal slots (68) which allow conveying air to exhaust from the duct upstream of the receiver.
