  Conventionally, as a method of producing pneumatic tires (hereinafter referred to as tire production method), intermediate products such as inner liner, carcass, bead part (bead core and bead filler), sidewall, tread and belt are separately manufactured and vulcanized. A method of assembling each intermediate in an assembly process including a process is generally widely known.

  In addition, when a pneumatic tire is defective in an inspection process or a market, a method in which an operator compares the process chart to find out the cause of the defect is generally widely known.

  Specifically, the worker specifies the manufacturing process of each intermediate constituting the pneumatic tire in which a defect has occurred and the assembling process of the pneumatic tire by comparing the process charts. Further, the operator checks the cause of the defect by checking whether an abnormality has occurred in the specified manufacturing process or assembly process (Lot trace).

  On the other hand, in quality control of a finished product such as a passenger car, a management device that manages the manufacturing process of each intermediate product constituting the finished product and the defect content of the finished product in association with each other has been proposed. The management device identifies a manufacturing process of intermediates associated with the defect content of the finished product when a defect of the finished product occurs in an inspection process or a market, and outputs a list including the specified manufacturing process ( For example, Patent Document 1).

  The worker confirms whether an abnormality has occurred in the manufacturing process included in the list by referring to the list output from the management apparatus.

Further, the manufacturing history information generation unit 160 generates manufacturing history information (downstream process → upstream process, see FIG. 7), which is a list of each searched information, so that the worker refers to the manufacturing history information. Thus, it is possible to easily find out which material causes the defective pneumatic tire.

  In addition, the manufacturing history information generation unit 160 has the material Lot No. of the material that caused the failure of the pneumatic tire. (Faulty Material Lot No.) is used as a search key to refer to the intermediate DB 140, and the bad material Lot No. The intermediate name associated with the intermediate Lot No. Search for the intermediate manufacturing date and manufacturing device name. In addition, the manufacturing history information generation unit 160 generates manufacturing history information (upstream process → downstream process, see FIG. 8) that is a list of each searched information, so that the worker refers to the manufacturing history information. Thus, it is possible to easily identify an intermediate that may cause a defect.

  Furthermore, the manufacturing history information generation unit 160 displays the defective material Lot No. The intermediate Lot No. The tire DB 150 is referred to as a search key, the tire name associated with the search key (intermediate Lot No.), the tire Lot No. Search for tire manufacturing date and assembly device name. In addition, the manufacturing history information generation unit 160 generates manufacturing history information (upstream process → downstream process, see FIG. 8) that is a list of each searched information, so that the worker refers to the manufacturing history information. Thus, it is possible to easily identify a pneumatic tire in which a failure may occur.

  That is, the manufacturing history information generation unit 160 refers to the intermediate DB 140 and the tire DB 150 to generate manufacturing history information (upstream process → downstream process, see FIG. 8), thereby causing the cause of a defective pneumatic tire. Even in the case where the intermediates and materials that have been used are commonly used for a plurality of pneumatic tires, it is possible to easily identify a pneumatic tire in which a defect may occur.

(Example of change)
In the embodiment described above, the manufacturing history management system 1 is a system for managing the manufacturing history of each device for manufacturing a pneumatic tire, but is not limited to this, and is common to a plurality of manufacturing devices. The system which manages the manufacture log | history of the manufacturing apparatus which manufactures a product using the common member used by using may be sufficient.

  In addition, a member is the concept containing the intermediate used when manufacturing the material used when manufacturing an intermediate, and a finished product. The finished product is a product manufactured using members (materials and intermediates). Furthermore, an intermediate is a product manufactured in the process of manufacturing a finished product, and is a product manufactured using a material in relation to a material. It is a member used when manufacturing.

  Further, in the above-described embodiment, the description has been made assuming that there is one type of synthetic rubber in order to simplify the description. However, the present invention is not limited to this, and the synthetic rubber may include a plurality of types of rubber (styrene butadiene). Rubber, polybutadiene rubber, polyisoprene rubber, butyl rubber, etc.).

  Furthermore, in the embodiment described above, the pneumatic tire has been described as having one type for the sake of simplicity, but the present invention is not limited to this, and the pneumatic tire has various specifications (size and size). A plurality of types of pneumatic tires having performance) may be used.

It is a figure showing manufacturing history management system 1 concerning one embodiment of the present invention. 1 is a block diagram showing a configuration of an IL manufacturing apparatus 10 according to an embodiment of the present invention. It is a block diagram which shows the structure of the manufacture log | history management apparatus 100 which concerns on one Embodiment of this invention. It is a figure which shows the information memorize | stored in material DB130 which concerns on one Embodiment of this invention. It is a figure which shows the information memorize | stored in intermediate DB140 which concerns on one Embodiment of this invention. It is a figure showing information memorized by tire DB150 concerning one embodiment of the present invention. It is a figure which shows an example of the manufacture log | history information which concerns on one Embodiment of this invention (the 1). It is a figure which shows an example of the manufacture log | history information which concerns on one Embodiment of this invention (the 2). It is a flowchart which shows operation | movement of the manufacture log | history management apparatus 100 which concerns on one Embodiment of this invention (the 1). It is a flowchart which shows operation | movement of the manufacture log | history management apparatus 100 which concerns on one Embodiment of this invention (the 2).
