  • Patent number: 8186278
    Abstract: A switch assembly for a conveyor is provided. The switch assembly includes a rail section forming a portion of the conveyor assembly. The switch assembly has a first gear assembly pivotable about a first pivot axis and carrying a first gate and a second gear assembly pivotable about a second pivot axis and carrying a second gate, the second pivot axis being positioned below a plane extending perpendicular to the rail section from the first pivot axis. A trolley stop assembly for a conveyor is also provided. The trolley stop includes a body having a first side portion and a second side portion arranged to be disposed on first and second sides of a rail section. A pivot member extends through the body and at least a portion of the rail section. A stop member is carried by an upper portion of the body and a weighted member is also carried by the body arranged to position the stop member for engagement with a trolley. A conveyor assembly including a switch assembly and trolley stop is also disclosed.

  • Patent number: 8020493
    Abstract: The present disclosure provides an apparatus for switching a vehicle from a first track to a second track. The track-switching device may be rotated by a motor, and may have a drive axle and a primary axle. The drive axle may have a barrel located at one end of the drive axle, the barrel having a plurality of switch tracks located thereon and a braking assembly connected to the drive axle and spaced from the barrel. The primary axle may have a flywheel and a clutch assembly. The drive axle may then be driven by the primary axle upon engagement of the clutch assembly via the motor and the energy stored in the flywheel. A method for switching a vehicle from a first track to a second track is also provided.

  • Patent number: 6539876
    Abstract: A guide rail switch for a robotic track system is provided, the robotic track system comprising at least one horizontal guide rail, at least one vertical guide rail, and at least one robot that can move along the guide rails. The switch comprises a frame coupled to the horizontal guide rail and the vertical guide rail, and a moving joint coupled to the frame, wherein the moving joint can move between a first and second position. A first rail section is coupled to the moving joint, wherein the first track section connects to the horizontal guide rail when the moving joint is in the first position. A second rail section coupled to the moving joint, wherein the second track section connects to the vertical guide rail when the moving joint is in the second position. This switch allows the robot to move between the vertical and horizontal rail depending on which position the switch is in.

  • Patent number: 5036773
    Abstract: The selective interconnection of tracks or slots coming together at a junction in a conveying system with push and pull operable conveying chains without return strands running in chain channels is accomplished by a switch constructed as a straight prism (21) mounted in a rotary manner. The prism has differently shaped chain channel portions (23', 23") on different ones of its sides. By rotating the prism (21) about its median longitudinal axis (22), that chain channel portion is positioned in the junction, which has the channel portions shaped to obtain the desired connection between the chain channel of selected entering and exiting tracks.
