From these things, an analysis device which simply verifies the consistency between the control program and its underlying operation plan has been desired.

  Further, in the prior art described in Patent Document 1, although the validity of the ladder program can be verified, the consistency between the program and the operation plan can not be confirmed. Also, in order to verify the validity of the ladder program, it is necessary to register simulation data in advance. Further, in the prior art described in Patent Document 1, although a timing chart is created, the driving time zone of each actuator is not reflected in the timing chart, and it is difficult to properly grasp the driving of each actuator. there were.

  Further, in the prior art described in Patent Document 2, the execution operation state diagram and the operation plan diagram can not be compared. Further, in the prior art described in Patent Document 2, although the driving time of each actuator can be grasped, a timing chart reflecting the driving time zone of each actuator is not created, and the driving of each actuator is grasped appropriately. It was difficult.

That is, the setting file indicating the operation plan of the manufacturing facility can be visualized in the form of a timing chart, and it can be easily verified whether the operation plan is appropriate. In addition, since the timing chart of the operation plan diagram can be compared with the timing chart of the execution operation state diagram created by executing the program based on the operation plan, the suitability of the operation plan and the appropriateness of the program configuration can be easily made. It is verifiable. In addition, since the measurement program is created, the address where the signal value of the actuator is stored can be read at high speed, and the timing chart of the execution operation state diagram can be created.

  The facility operation analysis apparatus 1 is for analyzing an operation plan for operating a manufacturing facility equipped with a machine tool driven by a plurality of actuators and an execution result of a ladder program 51 for operating the manufacturing facility. As shown in FIG. 1, the personal computer (PC) 10, a sequence unit 50, a CNC unit 60, and a robot control unit 70 are provided. The personal computer 10 also has an input unit 11, a measurement program creation unit 12, an operation plan diagram creation unit 13, and an execution operation state diagram creation unit 14, and a plurality of machine tools in a manufacturing facility. It is electrically connected to an actuator or the like.

  The input unit 11 can input various signal information. The input unit 11 inputs various signal information constituting an operation plan for operating an actuator in a manufacturing facility to a setting file 111 stored in advance in a storage medium (not shown) of the personal computer 10. The various signal information is stored, for example, in a data file stored in a storage medium (not shown) of the personal computer 10. Specifically, the operation state, operation time, operation command address (for each actuator) The command value address), the operation confirmation address (confirmation value address), the name, the operation end name, the operation confirmation timer, the pre-operation process (pre-operation), and the post-operation process (post-operation).

  Specifically, for example, as shown in FIG. 2, the setting file 111 is configured by a table having a format in which the drive timing and drive time of each actuator are input. For example, when focusing on "front door" as the name, SOL-11F2 as an actuator sets the front door in a "closed" state. In the table of the setting file 111, SOL-11F2 means that the front door is switched from the "open" state to the "closed" state in 1.8 seconds after 5 seconds from the start of operation in the manufacturing facility . Moreover, SOL-11F3 as an actuator is what makes a front door "open" state. In the table of the setting file 111, SOL-11F3 indicates that operation NO. From the point when the "close" operation of the M / C shutter by SOL-11F5 whose "NO. 4" is complete is completed, the front door is changed from the "close" state to the "open" state. I mean.

  The measurement program creation unit 12 is configured to automatically generate a measurement program based on the setting file 111 to which various signal information constituting the operation plan is input in the input unit 11. Here, based on the information of the setting file 111, the measurement program means a combination of an actuator to be monitored at the time of execution of the ladder program 51 and address information in which the signal value is stored in a program format. Using this measurement program, the execution operation state diagram creation unit 14 is configured to monitor each actuator and create an execution operation state diagram 141.

  The operation plan diagram creation unit 13 creates an operation plan diagram 131 based on various signal information that configures the operation plan for each actuator input in the input unit 11. Then, in the operation plan diagram 131, the operation plan diagram creation unit 13 indicates the drive time of the component part of the facility driven by the actuator and the drive amount of the component part of the facility corresponding to the drive time. Specifically, the operation plan drawing generation unit 13 reads the operation state and operation time of each actuator based on the setting file 111 in which various signal information constituting the operation plan is input in the input unit 11, and based on these. An operation plan diagram 131 reflecting each actuator driving time zone is created.

  More specifically, for example, as shown in FIG. 3, the operation plan diagram 131 is configured by a timing chart. For example, focusing on the "front door" as an item, the front door "closes" from the state of "open" from the state of "open" over a period of 1.8 seconds at a constant speed 5 seconds after the start of operation in the manufacturing facility. Indicates to be in the state. In addition, the front door indicates that the front door should be switched from the "closed" state to the "open" state at a constant speed for 1.8 seconds from the time when the "close" operation of the M / C shutter is completed. There is.

  That is, in the timing chart, the hatched portion indicates that the “front door” or “M / C shutter” described in the item is opened, closed, or lifted at a constant speed for a predetermined time. It indicates that they are going down, going forward, going backward, etc. In addition, in the timing chart, for example, a portion indicated by a rectangular waveform as in the item “1ST JIG high-speed rise” may be instantaneously switched from OFF to ON or momentarily switched from ON to OFF. It shows. Further, in the timing chart, the arrow extending upward or downward means that the operation start indicated by the tip of the arrow coincides with the end point of the operation indicated by the base of the arrow.

  The execution operation state diagram creation unit 14 generates an execution operation state diagram 141 based on the operation state of the actuator when the ladder program 51 created based on the various signal information constituting the operation plan input in the input unit 11 is executed. create. Then, in the execution operation state diagram 141, the execution operation state diagram creation unit 14 indicates the drive time of the component part of the equipment driven by the actuator and the drive amount of the component part of the equipment corresponding to the drive time.

  Specifically, based on the setting file 111 to which various signal information constituting the operation plan for each actuator is input in the input unit 11, the execution operation state diagram creating unit 14 connects the sequence device to be measured with the communication cable and Communication is performed, and among various signal information inputted in the input unit 11, an operation command address in which an operation command is stored and an operation check address in which the current operation state is stored are referred to. Based on this, the execution operation state diagram creation unit 14 creates the execution operation state diagram 141 (measurement result) reflecting the respective actuator driving time zones according to the operation time in a state of being superimposed on the operation plan diagram 131 and illustrated. Do. Then, the execution operation state diagram creation unit 14 outputs and displays the execution operation state diagram 141 on a monitor as a display unit of the personal computer 10.

  More specifically, for example, as shown in FIG. 4, a timing chart as an operation plan diagram 131 described by a solid line and a timing chart as an execution operation state diagram 141 described by a broken line are illustrated in an overlapping manner. (Comparison output). For example, focusing on “front door” as an item, the front door completes the “close” operation in a shorter time than the timing chart as the operation plan diagram 131 in the timing chart as the execution operation state diagram 141 It is shown. Similarly, in the front door, in the timing chart as the execution operation state diagram 141, the "open" operation starts earlier than the timing chart as the operation plan diagram 131, and the "open" operation is completed in a short time. Is shown.

  The sequence unit 50 has a ladder program 51 for operating an actuator or the like of the machine tool, and executes the ladder program 51 according to a predetermined operation from the personal computer 10 or a command signal from the CNC unit 60.

  The CNC unit 60 has a CNC system program that reads an NC program and numerically controls the movable parts of the machine tool, etc., and executes the CNC system program by a predetermined operation from the personal computer 10.

  The robot control unit 70 controls the robot so as to change the posture of the robot (not shown), the arm of the robot, and the like. Here, the robot (not shown) is an industrial robot having an articulated arm, and a base connected to the proximal end side of the arm is installed on a floor surface of a factory or the like. The robot (not shown) is configured to be able to switch to an arbitrary posture and change the arm to an arbitrary state under program control.

  Verification of the consistency between the ladder program 51 created based on the operation plan and the operation plan that is the basis of the operation plan using the equipment operation analysis apparatus 1 will be described with reference to the flowchart in FIG. FIG. 5 is a flow chart showing the operation of the equipment operation analysis apparatus 1 according to an embodiment of the present invention.

  First, in step S1, the input unit 11 inputs various signal information constituting an operation plan for operating an actuator in a manufacturing facility to the setting file 111. Specifically, the various signal information includes a name, an operation end name, an address (operation instruction address, operation confirmation address), an operation time, an operation confirmation timer, a pre-operation step (pre-operation), and an operation post step (back) Operation is included. Thereby, the setting file 111 into which various signal information as shown in FIG. 3 is input is created. Then, the processing in the facility operation analysis device 1 proceeds to step S2.

  In step S2, the measurement program creation unit 12 automatically generates and outputs a measurement program based on the setting file 111 to which various signal information constituting the operation plan is input in the input unit 11, and stores the measurement program in the storage medium of the personal computer 10. . And the process in the installation operation | movement analyzer 1 progresses to step S3.

  In step S3, the operation plan diagram creation unit 13 reads the operation state of each actuator based on the setting file 111 input in step S1, and creates the operation plan diagram 131. Then, the operation plan diagram creation unit 13 outputs the created operation plan diagram 131 to the execution operation state diagram creation unit 14 and stores it in the storage medium of the personal computer 10. Then, the processing in the facility operation analysis device 1 proceeds to step S4.

  In step S4, the execution operation state diagram creation unit 14 adds the measurement program created by the measurement program creation unit 12 in step S2 to the sequence unit 50 that is the measurement target. Then, the processing in the facility operation analysis device 1 proceeds to step S5.

  In step S5, the execution operation state diagram creation unit 14 reads the setting file 111 input in step S1, and performs connection and communication with the sequence unit 50 that is the measurement target via the communication cable. As a result, the execution operation state diagram drawing unit 14 acquires various signal information indicating the state of the signal input to the setting file 111 in step S1 by executing the measurement program in the sequence unit 50. And the process in the installation operation | movement analyzer 1 progresses to step S6.

  In step S6, the execution operation state diagram creation unit 14 creates the execution operation state diagram 141, and the execution operation state diagram 141 and the operation plan diagram 131 can be easily compared with the execution operation state diagram 141 and the operation plan diagram 131.
