摘要:
A jog-feed operation is set to enable rotation and movement of a coordinate system. During the jog-feed of the coordinate system, a robot is moved equivalently to the jog-feed steps. A tool distal end point of the robot is initially moved to the origin of a user coordinate system serving as a moving target. A jog-feed mode is set to a coordinate system jog-feed mode in conformity to the coordinate system itself. A translating jog-feed operation is carried out until the tool distal end point of the robot reaches a vertex of a workpiece. The tool distal end point of the robot is subsequently moved to a point on an axis of the coordinate system. A rotational jog-feed operation is carried out until the tool distal end point of the robot reaches an edge line of the workpiece. According to the above jog-feed operation, a robot control device calculates an amount of movement of the coordinate system.

An engine comprises a timer (20), which is provided with a temperature-sensing operation mechanism (7). During a cold-starting term, a downstream interlocking portion (2) advances by an advancing operation of the timer (20) based on an operation that the temperature-sensing operation mechanism (7) makes upon sensing the temperature. While the engine is warm, the downstream interlocking portion (2) cancels an advancement by an advancement-cancellation operation of the timer (20) based on another operation that the temperature-sensing operation mechanism (7) makes upon sensing the temperature. The engine oil (56) within the engine is supplied from the oil-supply port (58) to the timer (20), thereby enabling the engine oil (56) in liquid state to contact the temperature-sensing operation mechanism (7).

An operation data display device for a robot allowing an operator to recognize operation data on a plurality of operations performed by the robot at a time. When an arc start command is read out from a taught operation program by the robot controller, a welding start command is issued to an arc welding power supply. The arc welding power supply starts supply of a welding current to a welding torch mounted on a robot. Values of the welding current in a welding operation is outputted to a robot controller and sampled at every predetermined period and recorded. When an arc end command is read out from the operation program, the arc welding power supply terminates the welding operation and output of the values of the welding current. The robot controller transfers a file containing the data of the actual welding current to a personal computer. The personal computer displays representations of the received operation data in the form of line graphs of reduced size for the plurality of welding operations: in one frame on a display screen.

A program control system in a multitask environment to execute a plurality of programs in parallel. The system includes a program execution control device for controlling an execution of a plurality of programs, a first program and a second program which are mutually related, a subtask execution recognition device for recognizing a subtask execution command in the first program, and a resumption control device for resuming the first program in response to both a wait command in the first program and an end command in the second program of the task associated with the task of the first program. When the subtask execution command is recognized by the subtask execution recognition device while the first program is being executed, the second program is also executed. When the end command in the second program is detected while the first program is in a wait state under the wait command, the resumption control means allows the program execution control means to resume the first program.

A robot off-line simulation apparatus that allows a person to know an optimum placement for a robot, an operation margin index, etc. before going to an actual working site. Provisional robot placing positions are selected using data about a given sequence of task points (operation path), etc. The conditions for selection are (i) that solution to the inverse kinematics should be found regarding the entire sequence of task points, (ii) that the robot should not interfere with a peripheral device, and (iii) that regarding all the axes of the robot, the operation margin index should satisfy a criterion value. Simulation is performed according to operation programs under the condition that the robot is placed at each of the provisional placing positions, where data about cycle time, duty, energy value, change in acceleration/speed, etc. is collected. Using the collected data, evaluation of operation is performed regarding each of the provisional placing positions, and those provisional placing positions which allow good operation are identified as placing positions ensuring the robot operation. Further, using an evaluation function in which each aspect is given a weighting, the placing positions ensuring the robot operation are reduced to optimum placing positions ensuring the robot operation.

The present invention provides a multi-cylinder engine capable of inhibiting an EGR cooler from being damaged and at the same time making the EGR cooler compact. On the assumption that a direction where a crank shaft spans is taken as a front and rear direction and a widthwise direction of a cylinder head perpendicular to this front and rear direction is deemed as a lateral direction, an intake-air distributing passage wall is attached to one lateral side surface of the cylinder head and an exhaust-gas converging passage wall ached to the other lateral side of the cylinder head, the exhaust-gas converging passage wall having an interior area communicated with an interior area of the intake-air distributing passage wall through the EGR cooler. In this multi-cylinder engine, an intake-air inlet pipe is made to stand up at an upper portion of the intake air distributing passage wall and the EGR cooler is above the intake-air distributing passage wall. Further, the intake-air inlet pipe is arranged side by side with the EGR cooler.

A controller of an injection molding machine and a controller of a molded-product removing robot are connected to each other via communication means. When a molding condition save command is entered from the controller of the injection molding machine, a folder with a management number is created on a memory card, and molding conditions stored in the controller of the injection molding machine are saved in the folder. A teaching program and/or setting data stored in the robot controller is read via the communication means and saved in the same folder. When a molding condition read command is entered, data is read from a specified folder, molding conditions are set in the controller of the injection molding machine, and a teaching program etc. are set in the robot controller via the communication means.

An image of a reference object is captured using a camera and displayed. A measurement starting point is pointed by an image position pointing device. A corresponding view line is obtained using a position on the image and a position and a direction of the camera, a robot approaches to the reference object such that it does not deviate from a projecting direction to move to a position suitable for measurement. A light is projected on the reference object and measurement of an inclination of a face of the object in the vicinity of a measuring point is started. An image including a bright line image on the reference object is photographed and 3-dimensional positions of points sequentially measured along a working line. A movement path of a robot is created using these positions as teaching points for a working robot.
