PROBLEM TO BE SOLVED: To provide a tire production management system for collecting and managing data about tire molding by controlling each molding facility in each tire molding step, and provide a method thereof.SOLUTION: A tire production management system 10 in the invention comprises: a PLC 20 that issues a member ID to each member in a step for preparing members for tires and collects measurement data of each member corresponding to the member ID when the member is set in a molding drum; and a tire molding management unit 40 that, with respect to each of the tires, acquires the measurement data of each member corresponding to the member ID, which is collected by the PLC 20, issues a tire unique ID to each of the tires, and manages the measurement data of each member used to mold the tire upon associating the measurement data with the tire unique ID.

Description

  The present invention relates to a tire production management system and a method for associating a barcode that is accurately assigned to each tire and measurement data for each member even when a plurality of members are prepared at different timings.

  In the conventional tire molding system, mainly the work by the worker is the center, so that it has been possible to obtain a certain quality as to what state the members used for molding the tire are in the molding process. For example, when a member such as an inner liner, a carcass, a bead core, a side rubber, a belt, or a tread rubber, which is cut to a length substantially equal to the pasting circumference on the molding drum, is attached, It is possible to judge whether or not the measurement data such as the dimensions is good.

  Here, in order to cope with a large number of tire sizes, it is necessary to prepare the pasting member cut on the basis of a molding drum corresponding to the large number before the molding process for each tire size. Since a dimensional difference may occur for each cutting, it is common to collect measurement data of members in the tire forming process.

  On the other hand, in recent years, automation has progressed in the tire molding process (see, for example, Patent Document 1). For example, by assigning a barcode specifying the production date and time for each tire, the information on the production date and time can be used for each tire. Data management of these members is also possible.

  For example, FIG. 9 shows a system configuration example in a conventional tire production management system. The conventional tire production management system integrates a PLC (Programmable Logic Controller) 300 that controls the molding equipment in each molding process to collect data related to tire molding, and the data in each molding process. For example, a tire molding management device 400 including a personal computer (PC) that communicates with the PLC 300 via a network such as a LAN is provided.

  As shown in FIG. 9, in the conventional tire production management system, the tire molding management device 400 includes, from the PLC 300, “tire result data” consisting of barcode information for specifying the production date and time in each molding process, and the molding process. "Measuring data" consisting of measurement data and measurement date and time information of the parts used in, create a "tire result table" and a "measurement data table" that are listed in the order of production date and measurement date, respectively. Are registered in the database 410. Thus, for example, when the tire molding management device 400 is operated to refer to the measurement data of the member, the production date and time is specified based on the barcode information in the “tire result table”, and The corresponding measurement date and time in the “measurement data table” can be searched from the information, and the measurement data can be acquired.

JP 2004-174769 A

  However, in the conventional tire production management system shown in FIG. 9, even if the same type of member is used, measurement data is not given to each member that may cause a dimensional difference for each cutting, and the same type of member has different measurement data. When a plurality of members are prepared and used at different timings, the corresponding measurement date and time is retrieved from the production date and time information. For example, as shown in FIG. 9, for example, when the measurement date / time is searched in relation to the production date / time of the barcode “BC3”, the measurement data of the used member is “DATA3” or “DATA4”. I can't judge.

  Thus, in the conventional tire production management system shown in FIG. 9, the function of acquiring, recording and notifying measurement data for each member, and the correspondence between the measurement data for each member and the data in the tire performance table are 1 Since it cannot be managed on a one-to-one basis, a one-to-one association search cannot be performed as a relationship between measurement data for each member and one tire.

  For this reason, in the conventional tire production management system, since the relationship between the measurement data for each member and each tire is not completely 1: 1, there is a problem that the reliability between the data is lacking.

  In addition, in the conventional tire production management system, since the time data of the production date and time given to the final barcode in a series of flow work are tracked and referenced, Work data cannot be obtained at once.

  In addition, since the conventional tire production management system can only estimate the preparation / assembly time of a member used for one tire from the measurement date / time of the member, the measurement date / time of the member and the preparation / assembly time of the member As a result, the reliability of the parts actually used based on the production date and time may be lacking, and in order to cope with a large number of tire sizes, a molding drum corresponding to the large number is used. It is not applicable to a tire molding machine of a type in which a large number of members prepared as a reference are prepared for each tire size before the molding process.

  Therefore, an object of the present invention is to provide a tire production management system and a method thereof for associating a barcode attached to each tire accurately with measurement data for each member even when a plurality of members are prepared at different timings. Is to provide.

  A tire production management system according to the present invention is a tire production management system that collects and manages data related to tire molding by controlling molding equipment in each molding process of a tire, and includes a member for each member in a tire member preparation process. ID is issued and when each member is assembled to the molding drum, the PLC collects the measurement data of the member for each member ID, and the measurement data of the member for each member ID collected by the PLC is the tire. A tire forming management apparatus that issues a tire unique ID for each tire and manages measurement data of each member used for forming the tire in association with the tire unique ID. Features. Thereby, since member ID is provided to the member assembled correctly, the reliability of data comes to improve.

  In the tire production management system according to the present invention, for each tire, the PLC generates tire performance data in which tire bar code information specifying a production date and time is associated with measurement data of each member, and the tire molding management device. The tire molding management device associates the measurement data of each member used for molding the tire with the tire unique ID and registers it in a database as a member ID-specific measurement data table; And a means for associating the tire unique ID with a tire barcode specifying the production date and time and registering it in the database as a tire performance table. Thereby, since the measurement data of the member to be managed can be reliably associated with the barcode given on the molding side, the traceability of the member can be improved.

  An operation method of a tire production management system according to the present invention is an operation method of a tire production management system in which a tire forming management device controls a molding facility in each tire forming process from a PLC to collect and manage data related to tire forming. The member ID is issued for each member in the tire member preparation step by the PLC, and when each member is assembled to the molding drum, the measurement data of the member for each member ID is collected; The tire molding management device acquires the measurement data of the member for each member ID collected by the PLC for each tire, issues a tire unique ID for each tire, and is used for molding the tire. And managing the measurement data of the member in association with the tire unique ID.

This makes it possible to check the finished condition of the tire and manage lot traces in the tire molding process. Using a portable terminal or a host system terminal as a browsing function will help field workers and contribute to productivity. Become.

  Furthermore, according to the present invention, it is possible to retrieve measurement data of a single member by storing measurement data for each member. Thus, by taking a measurement history for each member, it becomes possible to provide a data base for managing the sign of the member, which contributes to a quality management system.

  Next, with reference to FIGS. 2-8, operation | movement of the tire production management system of one Embodiment by this invention is demonstrated.

[System operation]
FIG. 2 is an operation flowchart of the tire production management system according to the embodiment of the present invention. First, when a member i (i = 1, 2,...) Is prepared and put into a tire molding device 20 configured as a tire molding machine, the PLC 30 controls the tire molding unit 201 in the tire molding device 20. Then, the member ID issuing unit 2011 issues a member ID (serial number of the member i) for each of the prepared members, and the member measuring unit 2012 gives a member ID (for example, a dimension). (Measurement) is executed, information on measurement date and time and measurement data for each member ID (for example, serial number of member i shown in FIG. 3) is acquired (S1), and the same is collected when handling a plurality of member IDs. Then, the measurement data for each member ID (see, for example, “member i measurement data” shown in FIG. 4) is held in a predetermined area of the PLC database 31 (S2).

  Subsequently, the PLC 30 extracts the measurement data for each member ID (see, for example, “member i measurement data” shown in FIG. 4) from the PLC database 31 and transmits it to the tire molding management device 40 (S3). The PLC 30 may be configured to transmit the measurement data for each member ID (see, for example, “member i measurement data” shown in FIG. 4) to the tire molding management device 40 every time it is acquired from the tire molding device 20. .

  As shown in FIG. 4, the tire molding management device 40 creates the “measurement data table for each member ID” 41 a for each member by using the measurement data for each member ID acquired from the PLC 30 by the measurement data registration unit for each member ID 4021. And stored in the database 41 (S4).

  On the other hand, when the measurement of the member i is successfully completed, the PLC 30 controls the tire generation unit 202 in the tire molding apparatus 20 and the member ID use registration unit 2011 sequentially uses the member i according to the tire generation process. Each time, the member ID (serial number of member i) for each member is registered and held in the PLC database 31 as the “tracking table by member ID” 31a (S5).

  Subsequently, the PLC 30 is a list in which the member IDs (serial numbers of the members i) registered each time the member i is used sequentially in accordance with the tire generation process (see FIG. 5), and the PLC database 31. Is registered and held in the “tire result data management table” 31b (S6).

  When the generation of the tire is completed, the PLC 30 controls the tire barcode applying unit 203 in the tire molding device 20 to issue and assign a tire barcode specifying the production date and time for each tire by the tire barcode issuing unit 2031. At the same time, it is registered and held in the “tire result data management table” 31b in the PLC database 31 (S7).

  Subsequently, as shown in FIG. 5, the PLC 30 converts the tire actual data including the member ID (serial number of the member i), the tire generation date and time, and the tire barcode on the “tire actual data management table” 31 b into the tire molding. It transmits to the management apparatus 40 (S8).

  The tire molding management device 40 issues a tire unique ID by the tire unique ID issuing unit 4022 due to the reception of the tire result data, and associates the tire unique ID and the tie barcode by the tire unique ID tire result data registration unit 4023. The tire 41 is registered in the “tire result table” 41b prepared in advance in the database 41, and the tire unique ID is assigned to a predetermined field of the measurement data table for each member ID using the member ID as a key due to the issuance of the tire unique ID. The ID is recorded (S9).

  For example, when receiving a search request for a specific member from the communication terminal 50 (S10), the tire molding management device 40 searches the tire performance table 41b from the tire bar code information regarding the search member, and extracts the tire unique ID, Using the tire unique ID as a key, the member ID-specific measurement data table 41a itself is searched, and information on the member ID-specific measurement data table 41a in a form associated with the tire barcode is transmitted to the requesting communication terminal 50 ( S11). In addition, as an aspect of the search request regarding a specific member, for example, as shown in FIG. 7, a tire barcode and a name of a target member (for example, a member related to a bead core) are designated, or shown in FIG. In this way, it is conceivable to specify information on the measurement date and time and the name of the target member.

  As described above, according to the tire production management system 10 of one embodiment of the present invention, the measurement result data for each member of the tire molding device 20 can be reliably linked for each tire, and the measurement data for each member is measured. By storing, it is possible to search measurement data of a single member.

  The member ID is given when the tire constituent member is prepared in the tire molding apparatus 20, and is maintained as it is when the member is assembled. However, in the case of poor assembly, the member ID is used. Not to be. In addition, the measurement data can be data obtained by collecting the molding (winding) result for each member as data or by evaluating the state of the member.

  Moreover, PLC30 can be comprised as a controller which monitors each member, and you may comprise so that separate PLC may be provided for every shaping | molding process. As described above, various data of the members accumulated by the PLC 30 can be managed as tire data associated with the tire barcode by the tire molding management device 40.

  In addition, when issuing a member ID or issuing a tire barcode, a “member i serial number issuing table” or a “tire barcode issuing table” for assigning a serial number to each member i is prepared in advance. Also good.

  For example, various tables and data can be defined as follows.

・ Part 1 Serial No. Issuing table:
The serial number of member 1 A table for issuing (member 1 unique ID).
・ Part 2 Serial No. Issuing table:
The serial number of member 2 A table for issuing (member 1 unique ID).
・ Tire barcode issuing table:
A table for issuing tire bar codes.
-Member 1 tracking management table:
A table for managing tracking of the member 1.
-Member 2 tracking management table:
A table for managing tracking of the member 2.
・ Tire performance data management table:
The serial number of the member And table for managing tire barcodes.
Member 1 measurement data table:
A table (large capacity) for storing measurement data of member 1 and tire unique ID.
Member 2 measurement data table:
A table (large capacity) for storing measurement data of member 2 and tire unique ID.
・ Tire achievement table:
A table (large capacity) for storing tire generation date / time, tire barcode, and tire unique ID.
-Member 1 measurement data:
The measurement date of member 1 and the serial number of member 1 And data including measurement data of member 1.
・ Member 2 measurement data:
The measurement date of member 2 and the serial number of member 2 And data including measurement data of member 2.
・ Tire performance data:
Tire generation date and time, tire barcode, serial number for each member Data that contains

  When trouble occurs in member i, a new member is prepared and a new serial number is set. By issuing this, it is possible to ensure consistency with the tire barcode.

  Member i has all serial numbers. Since the measurement result for is stored, any search request for the member can be handled.

  Any unique tire ID can be applied as long as uniqueness is ensured.

  If some trouble occurs in the system and the tire performance data is stored before the measurement data for each member, the logic is built so that the tire unique ID is stored together when the measurement data for each member is stored later. It is preferable to do this. For example, tire unique ID, member serial number. Is used to manage stored data when data is written. The storage data management function performed at the time of writing in the tire molding management device 40 is also effective at the time of normal writing, that is, when storing the tire performance data after the measurement data for each member, and the reliability of the tire production management system. Will improve.

  As mentioned above, although this invention was demonstrated about one Embodiment, this invention is not limited to said embodiment, Various forms are included.

  According to the present invention, even when a plurality of members are prepared at different timings, the barcode attached to each tire can be accurately associated with the measurement data for each member. This is useful for applications using a machine, particularly for fully automatic tire molding machines.
