20130199403 | Friction Drive Conveyor Assembly - An overhead mounted friction drive conveyor assembly including a biasing section for biasing objects such as car doors. The conveyor assembly includes a conveying rail and a biasing rail extending in spaced and parallel relationship with the conveying rail. The conveyor assembly also includes at least three trolleys and at least two tow bars extending between and interconnecting the trolleys. A biasing mechanism allows at least two of the trolleys to remain on the conveying rail and guides at least one trolley onto the biasing rail so that one of the tow bars extends between the biasing rails. The object is disposed on the tow bar extending between the biasing rails. A plurality of friction drivers are disposed on the conveying rail for only driving the tow bar extending between the trolleys on the conveying rail. | 08-08-2013 |
20110060452 | Method And Apparatus For Radio-Controlled Friction Drive Conveyor System - A conveyor system having a conveyor path and friction drive spaced along the path to drive carriers along the path. Each friction drive is controlled by a drive controller, which communicates tracking, routing, and other information directly to other drive controllers within range via a wireless signal. The drive controllers may also directly communicate wirelessly with a central controller. If the central controller or a desired destination drive controller is out of range of a particular drive controller, that drive controller may communicate through other drive controllers until the desired destination drive controller is reached, or a drive controller that is within range of the central controller is reached. | 03-10-2011 |
20110056760 | Load Handling Bumper For Material Handling Device - A material handling device includes an automated guided vehicle configured for use with a carrier. Both the vehicle and the carrier include a bumper having a reflective target mounted thereon. The automated guided vehicle includes a sensor having a light source and a scanner for receiving a reflection from the light source. The light source directs a first light beam at the vehicle reflective target and a second light beam at the carrier reflective target. When the vehicle bumper is moved toward the sensor, the vehicle reflective target moves into a reflective position and when the carrier bumper is moved toward the sensor, the carrier reflective target moves into a reflective position. The movement of the either bumper into the reflective position generates a signal from the sensor to a controller to control the movement of the automated guided vehicle in response to movement of either bumper. | 03-10-2011 |
20110017572 | Stackable Carrier Assembly, System, And Method For Storing Carrier Assemblies - A stackable carrier assembly, carrier stacking system, and method of storing carrier assemblies is disclosed. The carrier assembly includes a base member presenting a load surface and opposite facing transfer surface. A plurality of carrier trolleys extend transversely from the load surface to engage conveyor tracks. A plurality of track sections are coupled to the load surface for receiving the carrier trolleys of another carrier assembly. The track sections are vertically aligned with the carrier trolleys. In a power and free or friction drive conveyor system, a lift device and telescoping arm can lift and stack the carrier assemblies so that track sections of one carrier assembly receive the carrier trolleys of another carrier assembly. In an overhead conveyor system, one carrier assembly can hang from the track sections of another carrier assembly. | 01-27-2011 |
20100296860 | Universal Framing Channel Mounting Bracket - An attachment system for securing conveyor components to a conveyor disposed between a pair of side guards. The side guards are U-shaped and have first and second side guard ends that extend perpendicularly from the opposite ends of a flat wall portion to a distal end. The first side guard end includes a first lip that defines a grooved portion. At least one framing channel extending between flat first and second channel ends is disposed between the first and second side guard ends. The first channel end includes a projection portion that extends from the first channel end to engage to the grooved portion to secure the first channel end adjacent the first side guard end. At least one tab extends outwardly from the second channel end to engage an end guard opening defined in the second side guard end to secure the framing channel to the side guard. | 11-25-2010 |
20100294906 | UNIVERSAL FRAMING CHANNEL MOUNTING BRACKET - An attachment system for securing conveyor components to a conveyor disposed between a pair of side guards. The side guards are U-shaped and have first and second side guard ends that extend perpendicularly from the opposite ends of a flat wall portion to a distal end. The first side guard end includes a first lip that defines a grooved portion. At least one framing channel extending between flat first and second channel ends is disposed between the first and second side guard ends. The first channel end includes a projection portion that extends from the first channel end to engage to the grooved portion of the side guard to secure the first channel end adjacent the first side guard end. | 11-25-2010 |
20100266381 | AUTOMATIC TRANSPORT LOADING SYSTEM AND METHOD - A method and system for automatically loading and unloading a transport is disclosed. A guidance system follows a travel path to a position near the transport and then a sensor profiles a transport so that a transport path is determined for an AGV to follow into the transport to place a load and for exiting the transport upon placement of the load. | 10-21-2010 |
20100213037 | Slider Bed Conveyor - The subject invention provides for a slider bed conveyor system that allows for lateral movement of a longitudinally moving conveyor of a fixed length. The system includes a first conveyor section having a first surface that extends between opposing first walls. A second conveyor section is operatively connected with the first conveyor section and includes a second surface that extends between opposing second walls. The first and second conveyor sections support the longitudinally moving conveyor and the second conveyor section is laterally moveable in relation to the first conveyor section. | 08-26-2010 |
20100104414 | Workpiece Transport Assembly And Method Of Using Same - A workpiece transport assembly includes an automatic guided vehicle having a guide wheel that drives the automatic guided vehicle along the production floor surface. A frame is releaseably attached to the automatic guided vehicle and defines a work area for assembling a workpiece. The automatic guided vehicle transports the frame to a reaction rail where the frame engages the reaction rail. A drive wheel assembly is mounted to the frame and includes a drive wheel that is movable between a drive wheel engaging position where the drive wheel engages the reaction rail to move the workpiece transport assembly along the reaction rail and a drive wheel disengaging position where the drive wheel disengages the reaction rail. The workpiece transport assembly is driven by at least one of the guide wheel and the drive wheel for movement through the assembly operation. | 04-29-2010 |
20100006393 | Diverter Assembly - A diverter assembly for conveyor systems that moves in a substantially linear direction in and out of the path of loads on the conveyor system. | 01-14-2010 |
20090271058 | Floating Forks For Lift Vehicles - A material handling vehicle, such as an AGV, for loading and unloading a transport and wherein the vehicle includes a pair of freely floating forks. The forks are freely moveable in the vertical direction as well as capable of pivoting or tilting about an axis relative to a fork carriage, however when a load is applied, the forks are locked are prevented from such free floating movement. | 10-29-2009 |
20080199298 | AUTOMATIC TRANSPORT LOADING SYSTEM AND METHOD - A method and system for automatically loading and unloading a transport is disclosed. A guidance system follows a travel path to a position near the transport and then a sensor profiles a transport so that a transport path is determined for an AGV to follow into the transport to place a load and for exiting the transport upon placement of the load. | 08-21-2008 |
