A workpiece transfer system or method is provided for transferring workpieces one set of pallets to another set of pallets using a workpiece transfer device that is movably attached to a robot. The workpiece transfer device uses mechanical devices to align the workpiece relative to the robot so that different types of workpieces can be placed into a pallet without the need of troublesome, expensive and complex image processing in which the workpiece holding positions are processed as images by using an imaging device such as a visual sensor. Preferably, the workpiece transfer device cooperates with a positional adjustment part such that the workpiece that is held by the transfer device contacts the the positional adjustment part to position the workpiece in a depthwise direction of the workpiece, a widthwise direction of the workpiece and a longitudinal direction of the workpiece.

A preliminary assembly system for joining a body side panel and a floor panel of an automotive vehicle in a loose-fit hemming joint state by bending a claw piece extending from a main body of one of the panels to hold the other of the panels, prior to welding. The preliminary assembly system comprises a die to be in contact with a back-side surface of the main body of one of the panels in a region forming a loose-fit hemming joint section. Additionally, a main bending blade is provided to be movable to approach the die to bend the claw piece until the loose-fit hemming joint state is established. The main bending blade is moved to approach the die by a movement amount which is mechanically determined relative to a surface of the other of the panels during formation of the loose-fit hemming joint section.

Method and apparatus of assembling vehicular body

A vehicle body transfer machine transfers a vehicle body along a transfer path by using a transfer truck with which the vehicle body is supported, wherein the transfer truck is returned to an initial starting position of the transfer path for a repeated use when transfer of the vehicle body is terminated. The vehicle body transfer machine comprises a jig change-over stage located before the initial starting position of the transfer path, a plurality of locator jigs including an upwardly directed locating pin, a plurality of lock units, an unlock-operating unit, and a jig change-over unit including a socket portion engageable with the locating pin of the corresponding one of the plurality of locator jigs. The socket portion is moveable toward the locating pin to be brought into engagement therewith under a first unlock condition established when the unlock-operating unit unlock-operates the plurality of lock units, which is correlated with the horizontal two directions, of the corresponding one of the plurality of locator jigs to perform a relative positioning in the two horizontal directions between the jig change-over unit and the corresponding one of the plurality of locator jigs.

Vehicle body transfer machine and method thereof

An assembling apparatus assembling a body side of an automotive vehicle includes: a moving body provided in a transfer line; a clamp device mounted to the moving body fixing and positioning a body side outer in an upright position in which the body side outer is fixed in such a manner that a roof rail end of the body side outer is positioned substantially above the side sill end of the body side outer; and a welding robot disposed in a side of the transfer line. The welding robot assembles the body side by welding the body side outer positioned by the clamp device.
