Problems solved by technology

However, in the method of Japanese Patent Laid-Open No. 08-187648, although the basic elements of production are combined, the speed-up of each basic element itself, such as a robot, is not involved. Therefore, there is still a limit to the speed-up of the entire production line.

Embodiment Construction

[0019] figure 1 It is a functional block diagram showing a schematic configuration of a production system 12 according to one embodiment of the present invention. The production system 12 includes a unit controller 11 and a plurality of industrial machines managed by the unit controller 11 . The unit controller 11 has a system operating information analyzer 21 that receives time-series operating information ( action information) to analyze the part that adversely affects the tact time of the production system 12 as a whole; the state quantity analyzer 22 analyzes the behavior of each of the industrial machines 31 based on the state quantities including sensor data that detects the state of the industrial machines 31 margin; program improver 23, which automatically corrects (improves) the speed or acceleration of the operating program based on the margin output from state quantity analyzer 22; and simulator 24, which confirms the operation performed by program improver 23 The ...

Abstract

A cell controller capable of optimizing the operation of a production system having a plurality of industrial machines operated by an operation program. The cell controller includes: a system operational information analyzer configured to analyze time-series operational information received from the industrial machines via a network, so as to find a part in the system which generates an adverse effect on a cycle time of the entire production system; a state quantity analyzer configured to analyze a state quantity of the industrial machines so as to calculate a degree of margin of motion of each industrial machine; a program modifier configured to automatically modify a velocity or acceleration in the operation program based on the degree of margin; and a simulator configured to execute an operational simulation of the production system in order to confirm a modification result of the operation program.

Description

technical field [0001] The present invention relates to a unit controller which optimizes the operation of a production system including a plurality of industrial machines operating by programs. Background technique [0002] Currently, various technologies are being proposed to increase the speed of the entire system in a production system including a plurality of industrial robots and industrial machines such as CNC machine tools. For example, Japanese Patent No. 3946753 describes a robot program evaluation / correction method that calculates the load of a motor for driving the moving parts of the robot through computer simulation, and stores the command speed and command for the motor in a time series. Acceleration and motor load, evaluate whether the motor load exceeds the allowable value through the evaluation function. [0003] In addition, Japanese Patent Laying-Open No. 08-187648 discloses a production line management system, which includes a plurality of unit controll...
