Patent number: 4691419Abstract: A turret is rotatably secured to a housing adapted to be secured to a robot wrist having a reference orientation and axis. The turret has a plurality of interchangeable lead processing devices which are selectively aligned to the reference orientation and axis. When so aligned a lead processing device is engaged with a selected component and operated to cut and bend the lead of that component. A second component's lead may be processed by the same or a different lead processing device secured to the turret. The latter device is aligned to the reference orientation and axis prior to processing the second component's lead. The robot is programmed to align the reference axis and the corresponding processing device to the selected component whose lead is to be processed.Type: GrantFiled: November 12, 1985Date of Patent: September 8, 1987Assignee: RCA CorporationInventors: Brian G.

Patent number: 4685067Abstract: An apparatus is provided for controlling the execution of functions associated with the automatic operation of a manipulator. While traditional function execution has been associated with arrival of a workpoint at or proximate to a predetermined point, the present invention provides for plural function execution between predetermined points. Two alternative embodiments are provided: a first embodiment controls a single output interface type and is unrelated to functions associated with predetermined points; a second embodiment provides multiple executions of any function normally associated with a predetermined point. Spacing between function executions associated with either embodiment is controlled as a function of distance specified by the operator. To produce a desired spacing, feedrate reduction is automatically effected in the event a programmed feedrate is incompatible with a specified function execution interval.Type: GrantFiled: February 20, 1986Date of Patent: August 4, 1987Assignee: Cincinnati Milacron Inc.Inventors: Daniel B. French, Richard E. Brookshire, Joseph W. Schnelle

Patent number: 4650388Abstract: A device for the disconnectable coupling of a support toggle joint of a gripper to the end of a slave arm of a remote manipulator. The arm and toggle joint each have a case in which are located means for transmitting movements to the gripper. The coupling device comprises at least two latches pivotably mounted on one of the cases and which are able to occupy a coupling position in which they bear against pins fixed to the other case. This couples the toggle joint to the end of the arm and the latches can also occupy a position in which they are disengaged from the pins in order to disconnect the toggle joint.

Patent number: 4605569Abstract: A method and apparatus for performing repetitive cycles of panel coating operations using a programmable manipulator including a manipulator arm movable along a plurality of axes. The apparatus comprises a hand unit carried on the manipulator arm. The hand unit is movable so as to bring the brush held by it into resilient contact with an area of the panel to be coated. A coating material is injected into the brush at a predetermined rate while the brush is held in resilient sliding contact with the panel and while the manipulator arm moves about the panel to coat a preselected area of the panel. After the preselected area of the panel has been coated, the manipulator arm is moved to move the brush out of contact with the panel. Between coating cycles, the manipulator arm moves the brush into a storage chamber where it is treated to prevent the coating material from caking on the coating brush.Type: GrantFiled: November 21, 1983Date of Patent: August 12, 1986Assignees: Nissan Motor Co., Ltd., Sunrise Meisei CorporationInventors: Yoshitaka Shimada, Kimihiro Kadowaki, Teruo Inouchi

Patent number: 4542794Abstract: The alignment of the drill stem and bit of a rock drill rig is corrected when the force of drilling and the feeding power on the drilling machine of the rig has resulted in a change in the direction of the drill stem because of deformation of the articulated and extensible drill boom of the rig and of its pivotally supported drill support on the drill boom. The drill rig is of the type that includes elements for measuring boom lengths and articulation angles, servos for controlling such lengths and angles and a control unit which is connected to the measuring elements and servos for adjusting the drill stem and bit. The various articulation angles which are required to compensate for deformations of the drill boom and drill support are determined as if the drill boom and support were in an unloaded condition, on the basis of measured values of the boom lengths and articulation angles which have been registered in the control unit in an unloaded condition.Type: GrantFiled: April 26, 1982Date of Patent: September 24, 1985Assignee: Ingenior Thor Furuholmen A/SInventor: Hakon E.
