Abstract: An automated modular quality control center assembly for tubulars having an automated inlet module, an automated transfer module, and an automated parameter defined segregation module. The automated inlet module has a pipe conveyor, which receives the tubulars from an initial pipe rack. The tubulars are rolled off the automated inlet module pipe conveyor to an automated transfer module pipe conveyor. The tubulars on the automated transfer module pipe conveyor pass in close proximity to and are scanned by the survey instrument detector. An automated pass fail pipe conveyor receives the tubulars from automated transfer module pipe conveyor. A pass test exit pipe rack or a fail test exit pipe rack receives the tubulars from the automated pass fail pipe conveyor that pass or fail a preset survey instrument limit of the survey instrument detector.

Abstract: An automated vehicle system for laying pipe includes a vehicle (e.g., a stringing trailer) with a bed for storing a plurality of pipes. Tilted gravity members extend across the bed of the vehicle to feed the pipes toward a chute with conveyor running toward the rear of the vehicle. A gate arm and rocker arm mechanism ensure that pipes are fed one at a time onto the conveyor to lay a series of pipes on the ground. Optionally, a joining trailer can be connected behind the vehicle for joining the pipes together before the pipe is placed on the ground.

Abstract: For use in loading heavy sticks of plastic pipe into a pipe fusion machine, a pipe storage rack with hydraulically powered pipe stick dispensers and stands allows sticks of pipe stored on the rack to roll gravitationally onto a rocking V-shaped dispenser cam disposed between the rack and the fusion machine loading path for one-stick-at-a-time loading onto powered track and roller stands which enable Cartesian manipulation of the stick into the fusion machine. The cam is adjustable to suit pipe stick diameters ranging from 20? to 48?. Many sticks can be stored at one time, releasing heavy lifting equipment and operators to work elsewhere. The process requires only one operator using a pendant controller and the pipe sticks are handled by heavy equipment only when being loaded onto the racks.

Abstract: Disclosed is a bar feeder, which is capable of reliably loading a bar onto a guide rail with a simplified structure. The bar feeder 1 comprises a stock rack 8, a guide rail 4 for guiding a bar to a bar machining apparatus, and a bar supply mechanism 32 for taking bars W one by one out of the stock rack 8 and supplying the taken-out bar W onto the guide rail 4. The bar supply mechanism 32 includes a lifting member 40 adapted to lift a downstreammost one of the bar W on the stack rack 8, a bar receiving member 42 adapted to receive thereon the lifted bar W and supply the bar W onto the guide rail 4, and a stopper member 36 adapted to holds a second-downstreammost one of the bar W to be subsequently supplied. The lifting member 40 and the bar receiving member 42 are adapted to be driven by a common moving device 44, in such a manner that the lifting member 40 is linearly moved in an upward-downward direction in conjunction with a swing movement of the bar receiving member 42.

Abstract: A teeter beam assembly is provided for attachment to a pipe launcher that can be tilted towards or away from the pipe launcher to move joints of drilling pipe on to or off of the pipe launcher by rolling pipes with the assistance of gravity. The teeter beams assembly can consist of a frame, a pair of vertical guide assemblies on each of the outer and inner ends of the frame, a longitudinal beam glidably coupled to the guide assemblies and a pair of rams coupling the beam to the frame for raising and lowering either end of the beam with respect to the frame.

Abstract: This invention provides log singulators which allow for the vertical singulation of piles of logs fed from typical in-feed log decks, so that these logs may be fed individually to typical out-feed conveyors. Devices provided by this invention may be high-speed singulators occupying minimal floor space area. Singulators provided by this invention comprise arcuately oscillating lifting devices (“primary lifting devices”), preferably rotating synchronously in opposite directions. Preferably, these singulators elevate logs against vertically successive barriers. These barriers are shaped so that only one of either a largest log or a smallest log, which it is expected that the singulator should handle, can rest on the primary lifting devices and be carried upward at a time.

Abstract: A device for transferring bars from a magazine into the guiding channel of a feeder for feeding a machine tool, the magazine comprising an inclined surface for supporting the bars having a side for unloading bars into the channel, adjusters for adjusting inclination of the supporting surface, elements for retaining bars on the surface, and bar pickers which are actuated to disengage the lowermost bar from the retention elements and move it to a level for falling into the channel, and actuators for simultaneously actuating the adjusters and the retention elements for inclination and position adjustments suitable to accommodate variations in the diameter of the bars to be transferred.
