Embodiment Construction

[0046] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0047] figure 1 It is a configuration example of a process management system as an embodiment of the present invention. The configuration of the process management system of this example will be described by taking the case of managing the production process of an automobile factory or the like as an example.

[0048] Figure 27 It is a schematic diagram of a production line in the automobile manufacturing process. First, refer to Figure 27 The outline of the production line in the automobile manufacturing process will be described. The automobile manufacturing process consists of a plurality of lines such as the main line 50 for manufacturing and assembling parts such as car bodies, and the sub-line 60 for manufacturing parts such as bumpers that are incorporated into the car body. The main line 50 is composed of a plurality of processes 51 to 53, and each proc...

Abstract

The invention provide a process control system that can issue a work instruction sheet in the initially planned sequence order in the sub-line production process, even if the sequence order of the product in the main production line is changed. The process control device includes a tracking controller (11) receiving event information indicating that a product pass a predetermined location is received, and controlling the current position and sequence status of the products; a conductor unit (12) for determining a corresponding process based on the event information; and a work instruction unit(14) for issuing a work instruction for the product in the production line in response to the request from the conductor unit. The device further includes a work instruction past record control unit(15) for controlling past record of the work instructions in response to an issue of the work instruction; a work instruction sequence order control unit (13) for controlling a sequence order of the work instructions; and a work instruction sequence order storage (18) for storing information of the sequence order of the work instructions. Thereby, the control to the information of the sequence order of the work instructions in addition to the current location information of the product is realized.

Description

technical field [0001] The present invention relates to a process management system for performing position management of produced products and sequence management required for work instructions on a production line composed of multiple production processes. Background technique [0002] For example, on a production line for manufacturing automobiles, there are multiple production processes consisting of an assembly line for main parts such as the body of the product, and a sub-line for manufacturing parts such as doors and bumpers that are incorporated into the body and supplying them to the main line Do your homework. In each process of these production lines, when the body to be worked is circulated in an orderly manner, a work instruction according to the product specification corresponding to the body is output, and the on-site operator or the robot for assembly work refers to the work instruction to carry out the work . [0003] However, in this kind of production li...
