Abstract: A working line having a plurality of work stations arranged in series and a free-flow transport conveyor for transporting workpieces to the work stations. An outer frame supporting the conveyor extends over the work stations. A jig base is provided in each of the work stations and is inserted into a framed space of the outer frame. A jig is provided on each of the jig base supporting and positioning each of the workpieces on the transport conveyor at the respective work station. The transport conveyor includes a main transport conveyor on the outer frame, a plurality of pallets riding on the main transport conveyor, and a return conveyor supported on the outer frame under the transport conveyor for returning empty pallets to a starting end of the line. The transport conveyor and return conveyor comprise, respectively, a pair of right and left conveying members provided in parallel to each other on both lateral sides thereof.

Abstract: An apparatus having a robot on an frame having in front thereof a jig base for positioning thereon workpieces to which parts are to be assembled. The robot supports an assembling head equipped with a parts-holding member movable in a longitudinal and a vertical direction towards and away from the jig base so that the parts can be picked up out of a parts-containing pallet supplied at a predetermined pickup position on the frame and assembled to the workpiece positioned on the jig base. A pair of front and rear pallet chambers are formed in a space under the frame such that parts-containing pallets can be brought in and taken out in a stacked condition, one of the chambers being used as a feeding pallet chamber and the other as a discharging pallet chamber.

Abstract: The fly wheel and the ignition coil are set on the set jig with a comparatively large space left therebetween so that the two do not adhere to each other during the placement thereof. After the fly wheel and the ignition coil are placed on the set jig and are delivered to the two holding means of the assembling jig, a large space is maintained between the fly wheel and the ignition coil so that when the fly wheel is turned to be aligned, there is no magnetic force acting between the fly wheel and the ignition coil. Thus, the fly wheel can be easily assembled to the crankshaft. Thereafter, the ignition coil is brought to approach the fly wheel and is assembled to the engine main body where it is located at its normal facing position in relation to the fly wheel.

Abstract: An automatic assembling apparatus is provided for assembling in sequence at least a first component and a second component to an article at an assembling station. The assembling apparatus comprises a first assembling jig for the first assembling component and a second assembling jig for the second component. An annular rail has the first and second assembling jigs mounted thereon such that they are circumferentially movable on the annular rail. The annular rail has a movable rail portion positioned opposite the assembling station which is movable to advance toward and retract from the assembling station. At least one supplying station is positioned with respect to the circumference of the annular rail for supplying components to the assembling jigs at the supplying station.

Abstract: The present invention is directed to an apparatus for assembling a uniform-speed joint having an inner rotary body and an outer rotary body which transmits a rotational force from one to the other through a plurality of small spheres disposed in receiving holes in the outer peripheral surface of the inner rotary body. The apparatus comprises a carrying member for carrying the outer rotary bodies such that the inner surface of the rotary body is oriented upward and guide members, including a first guide wall, a second guide wall and a pusher for pushing an inner rotary body along the first guide wall until it contacts the second guide wall.

Abstract: Therein is disclosed a method for assembling a uniform-speed joint having an inner rotary body and an outer rotary body which transmits a rotational force from one to the other through a plurality of small spheres in receiving holes on the disposed outer peripheral surface of said inner rotary body and including a pair of small spheres diametrically facing each other where the intersecting angle between the rotation axes of said inner rotary body and said outer rotary body is variable and the rotational speed is not changed.

Abstract: Water contaminated with oil is separated within a closed container into an oil layer and a water layer containing a residue of oil, because of the difference in the specific gravities of water and oil. A suction pump sucks the separated oil from the container to reduce the pressure of the liquid in the container, thereby lowering the concentration of oil residue in the separated water.
