  • Patent number: 4747193
    Abstract: An apparatus for supplying a pallet to a machine tool has two rows of pallet supports and a pallet carrier between the two rows. The two rows of pallet supports consist of one or more modules so that a change of the number of pallet supports can be easily achieved. The pallet carrier moves along and at a right angle to the two rows, and can be positioned under a desired pallet. The pallet carrier lifts the desired pallet and transfers it to the machine tool by only linear movement.

    Abstract: A welding robot is provided with a first joint member in addition to a welding gun. A work holder provided with a second joint member adapted to be connected with the first joint member and a clamp mechanism for gripping a workpiece is positioned in a predetermined waiting position. The welding robot accomplishes welding on a workpiece transferred to a first station and when the welding is completed, the welding robot approaches the work holder in the waiting position to connect the first and second joint members with each other. Then the robot returns to the first station carrying the work holder and permits the clamp mechanism of the work holder to grip the workpiece at the first station. Thereafter, the robot moves to a second station to transfer the workpiece from the first station to the second station. Then, the clamp mechanism releases the workpiece and the robot moves away from the second station to the waiting position with the workpiece left at the second station.

  • Patent number: 4738387
    Abstract: The invention is concerned with the design of processing stations for the processing, by welding technology, of semi-finished vehicle body subassemblies (5) within the framework of a flexible manufacturing system. Thereby, frame-like work piece carriers (1) with support members (4) are used for loose positioning of components of the subassemblies (5), where the work piece carriers (1) are also capable of accepting differently configured subassemblies. The transfer line (9) is not planned as a single line, but includes only the input station (10), the work position (6) and the output station (11). Next to these stations (10, 11), storage stations (14) are arrayed, which are connected with one another by a transport system (20) which crosses the transfer line (9). In this manner it is made possible to store the work piece carriers (1) with the processed subassemblies (5) or to bypass the next work station if it is not capable of receiving (a work piece carrier), or is out of order.

  • Patent number: 4664575
    Abstract: Workpieces to be machined are stacked on all but one of a series of uniformly spaced vertical guide bars on a turntable movable along a transfer path. An elevator mechanism moves into engagement with the turntable and lifts a carrier with a stack of workpieces to be machined on one of the guide bars so that the uppermost workpiece is in a position to be grasped and transferred to a machine tool by a robot arm. The elevator also positions a workpiece carrier on an adjacent guide bar so that the carrier is positioned for the stacking of machined workpieces thereon by the robot arm. The workpiece carriers are positioned by the elevators in response to signals from photoelectric detectors. When all of the workpieces on one carrier are machined and stacked on an adjacent carrier and said one carrier is unloaded, the elevator mechanism is temporarily separated from the turntable and the turntable is rotated by the distance of twice the spacing between adjacent guide bars.

  • Patent number: 4527326
    Abstract: A part feeding and assembling system comprises a bowl feeder composed of storage container for storing parts to be assembled and a transporting track for transporting the parts in a row, the transporting path having an end opened in the interior of the container, a visual recognition apparatus for imaging the parts being transported, determining whether the part as imaged is proper for assembling currently carried out, and recognizing position and direction of the proper part, and a robot for picking up the proper part by generating pick-up position data of the robot on the basis of the data representative of the position and direction of the proper part and assembling it to a part to be assembled at other station. The robot picks up only the proper part from those being transported. The bowl feeder introduces the improper parts to the container through the opening so that they are again placed on the transporting path for being recirculated.

  • Patent number: 4520966
    Abstract: A wire canister capable of being used by robots during the assembly of a wire harness. The wire canister is capable of accepting, storing and dispensing random lengths of wire, i.e., a wire segment. The leading and trailing ends of the wire segment are constrained in such a way that the ends of the wire segment may be readily acquired by the manipulator of a robot and presented to other supporting equipment for purposes of performing operations on the ends of the wire segment.

  • Patent number: 4486843
    Abstract: A controller for a manipulator or robot having a plurality of power-driven, signal-controlled links interconnected to permit relative motion therebetween to define plural degrees of freedom. The links of the manipulator are controlled to perform movements corresponding to stored sequences of command positions. The controller stores, for each link, a sequence of command positions and is operable to add a further command position or a further sequence of command positions to the original sequence of command positions. In a non-synchronous mode of operation (where the movements of the robot are not sychronized with movement of the workpiece) or in a synchronous mode, a further command position is added to the end of the original sequence by producing a number of additional command positions and storing the additional command positions after the original sequence. The last of the additional command positions is substantially equal to the further command position.

  • Patent number: 4484294
    Abstract: A method and apparatus for real time editing, or modifying, of a program of prerecorded robot motions stored in a robot controlled memory while it is being processed by the controller for subsequent storage of the program, as edited, in memory and output to the robot for execution.
