Embodiment Construction

[0015] (1. Outline of Cyber-Physical Systems Production System)

[0016] Hereinafter, a Cyber ​​Physical Production System (Cyber ​​Physical Production System: hereinafter also simply referred to as "CPPS") will be described with reference to the drawings. Such as figure 1 As shown, CPPS (hereinafter, also simply referred to as "production system") includes a production line 10 arranged in the real world and a production line computer device 20 arranged in the virtual world.

[0017] (2. Structure of production line 10)

[0018] The production line 10 includes at least a grinder 11 as a machine tool, a heat treatment furnace 12 arranged upstream of the grinder 11 , and an inspection machine 13 arranged downstream of the grinder 11 as adjacent processing machines to produce workpieces W. In addition, the production line 10 includes a control device 14 that controls the grinder 11 , the heat treatment furnace 12 , and the inspection machine 13 based on the production command v...

Abstract

The invention provides a production system of a cyber-physical system type, comprising a production line and a line computer device that generates a virtual production state in a virtual world that corresponds to an actual production state in the production line. The production line includes a grinding machine, a heat treatment furnace, a testing device and a control device. The line computer acquires a set of production instruction values by being synchronized with the control device, and creates the virtual production state by creating a grinding process, a virtual heat treatment, and a virtual inspection process in the virtual world. The line computing device outputs a set of optimal production instruction values to the control device so that a production condition of the production line is satisfied.

Description

technical field [0001] The present invention relates to a cyber-physical system type production system. Background technique [0002] Generally, a production line that sequentially conveys and produces workpieces includes various machines, each of which performs processing based on production command values ​​set in advance according to production conditions. Various machines include machine tools. For example, a grinding simulation device disclosed in JP-A No. 2018-153907 can simulate machining processing of a machine tool. Preliminary simulation processing can set production command values ​​according to production conditions with high precision, and as a result, productivity of the production line can be improved. [0003] However, in the above-mentioned conventional production line in which various machines constituting the production line perform processing independently, the processing of the workpiece by the machine on the upstream side of the production line may aff...
