Description

The present invention relates to a work support system that supports work performed by a worker on a production line.

Generally, a factory production line is configured to include a work support system that supports the work performed by a worker. There are various types of work support systems. For example, a work support system that supports the work of assembling a product tells a worker which tool among multiple tools is used to perform the work, informs the work procedure, and the work is performed correctly. Support actions such as giving a warning when there is no such operation are performed according to the progress of the work. When constructing a production line, such a work support system is created according to the configuration of the production line, for example, the arrangement of various devices used in the production line.

The production line of the factory is a combination of industrial equipment including a control device called PLC (Programmable Logic Controller), so that PLC controls other industrial equipment to perform a series of operations to manufacture products. Is built on. The PLC decodes a control program individually prepared for each production line, and controls the industrial equipment to be controlled according to the instructions described in the control program. Conventionally, the control program has been constructed by scratch, that is, from the beginning, according to the configuration of the production line. Similarly, for the work support system introduced in the production line, it was necessary to construct a control program for operating the control device that controls the entire work support system according to the configuration of the production line.

However, constructing the entire control program by scratch is inefficient because it takes time to start up the production line. Therefore, for example, the PLC manufacturer provides a sample program that can be used in the production line construction work, or provides an application package equipped with the functions required for the production line construction work, thereby providing the production line construction work. It was possible to realize the simplification of. For example, the program creation support system described in Patent Document 1 stores a function block used for creating a PLC program, a screen component used for creating a program of a programmable display, and cooperation information for associating the function block with the screen component. The library is provided, and the cooperation information is used to realize the cooperation between the work of creating the PLC program and the work of creating the program of the programmable display. As a result, the workload of the user is reduced.

The second program unit 112 is configured so that the program can be changed from the outside, such as the addition of a new functional block 112B and the addition of a new ladder program 112C. Since the function block 112B and the ladder program 112C can be changed from the outside, the user can change the function block 112B and the ladder program 112C by adding at least one of the function block 112B and the ladder program 112C. It is possible to realize the required functions individually and specifically.

That is, the application program 110 that realizes the work support system 1 according to the present embodiment includes the first program unit 111 for the purpose of cooperation with other work support systems 1n. Further, in the application program 110, only by setting the value of the parameter for cooperation of the first program unit 111, the plurality of functional blocks 111B included in the first program unit 111 can be used as an application program of another work support system 1n. It is designed to be able to cooperate with 110n. Therefore, it becomes easy to create a program for a part related to cooperation with another work support system 1n, and the workload of program creation can be reduced. As a result, the construction work of the work support system 1 becomes easy, and by extension, the construction work of the production line of the factory can be facilitated.
