Abstract:
A traveling route structure of a conveying traveling body has a traveling route with an area intersecting a crossing aisle, and has a movable rail horizontally openable and closable between a connection working position that connects guide rails in front and rear of the crossing aisle and a retracting position lateral to the crossing aisle. The movable rail has front and a rear movable rails arranged in a line when the movable rails are in the connection working position. Each of the movable rails is pivotally supported so as to be horizontally rotatable about a vertical spindle at each outer end portion positioned outside of the crossing aisle. A locking means couples inner end portions of both movable rails together, with the inner end portions being adjacent to each other when the movable rails are in the connection working position.
Abstract:
A slip tube system is configured to transport a load along a conveying path of an overhead conveyor system. A stationary frame has at least one rotating shaft with a shaft axis extending along the conveying path of the stationary frame, and a movable carriage configured to transport a load along the conveying path. A slip tube is placed on at least one of the least one rotating drive shafts and each slip tube has an inner diameter larger than the outer diameter of a respective drive shaft, and is in rotational sliding engagement therewith. At least one driven wheel is attached to the carriage to engage with an exterior of the slip tube surrounding the at least one rotating drive shaft to push the slip tube into driving engagement with the rotating shaft, and to rotate the slip tube therewith. The driven wheels are canted with respect to a shaft axis of the drive shaft and slip tube, and the canted contact produces a helical loci of engagement between the exterior of the slip tube and each of the driven wheels. As the drive shaft rotates, traction is developed between the rotating shaft and an inner surface of the slip tube, and between an outer surface of the rotating slip tube and the driven wheels to provide sufficient drive force to propel the carriage and the load along the conveying path.
Abstract:
A column guided and supported self-propelled vehicle which is rigid in its pitch and roll axes but flexible in its yaw axis. The vehicle thus forms a beam between a series of columns which support and guide the vehicle. The vehicle is propelled by a flexible rotating screw which rotates against lugs which are mounted on each column. The vehicle is supported in the pitch axis and constrained in the roll axis by rollers, which are mounted on each column. A retainer on each column prevents the vehicle from leaving the column. The length of the vehicle determines the spacing of the columns. The vehicle is flexible in the yaw axis so that it can negotiate a curved path of columns. The vehicle car body/structure is modular and contains a series of vertical hinges or flexures which are located between each module to allow the vehicle freedom only in the yaw axis. Fixed to each module of the car body/structure are linear displacement components which determine the relative position of each module in order to align the vehicle when it is entering or leaving a curved path of columns. The linear displacement components receive positional information from the guidance and support columns.
Abstract:
An accumulation system for driverless vehicles of the type which are propelled along a track by contact between the drive wheel and a rotating drive shaft. Accumulation being caused by contact between a swing arm extended from the front end of a driverless vehicle. The swing arm pivots towards the front end of the driverless vehicle causing a corresponding rotation of the drive wheel with respect to the rotating drive shaft. The change in position of the drive wheels with respect to the axis of the drive shaft causes a deceleration of the driverless vehicle and/or accumulation of the vehicle with respect to the adjacent driverless vehicle on the track.
Abstract:
The speed of a driverless vehicle is controlled along the length of the module from an incoming high speed to an outgoing low speed or vice versa. The module includes first, second and third aligned drive tubes between tracks adapted to support a vehicle. A first motor is coupled to the first drive tube for driving the same at a first high speed. A second drive motor is coupled to the third drive tube for driving the same at a second low speed. Clutch means are provided for enabling only the first motor to drive said first and second tubes and then enable only the second motor to drive the second and third tubes.
Abstract:
The drive shaft assembly comprises first and second telescoping shafts supported above ground level. A motor is coupled to the first shaft for extending it in an axial direction. Another motor is connected to the second shaft for rotating the second shaft about its longitudinal axis. These shafts are connected by a coupling so that the second shaft rotates the first shaft in all positions of the first shaft. The first shaft terminates at a free end in a frictional engageable end portion.
Abstract:
A driverless vehicle for riding on a track has a drive wheel driven by a drive tube. The drive wheel is coupled to a substrate which in turn is coupled to the deck so that a portion of the load is transmitted to the drive wheel and the remainder of the load is transmitted through a separate substrate to the support wheels.
Abstract:
A driverless vehicle has at least one drive wheel mounted on a base and oscillatable about the axis of its support between a drive position and an accumulation position. A cam is supported on the base by a horizontal parallelogram linkage with one leg of the linkage connected to the drive wheel support for moving the drive wheel support between said positions. A ground supported cam follower is provided for actuating the cam.
Abstract:
A shuttle vehicle reciprocates between sets of tracks for driverless vehicles. The linear movement of the shuttle vehicle causes a turntable on the shuttle vehicle to rotate. The turntable is adapted to support a driverless vehicle to be transported from one set of tracks to another.
Abstract:
The article delivery device of the present invention is in the form of a conveyor system having a main branch with one or more auxiliary branches coupled thereto for use in connection with vehicles which are driven by frictional contact between a rotating drive shaft and a drive wheel coupled to the vehicle.
