JP 2001-191174 A

  However, the quality data management system disclosed in Patent Document 1 is directly stamped on a product or printed on a product tag attached to the product in order to associate the quality of the product and data indicating various operation states of the equipment with the product. You need to enter or recognize the correct product number. For this reason, this quality data management system requires labor and cost for directly stamping a product number that is different for each product on a product or printing it on a product label or the like. Further, this quality data management system may take time to input or recognize the product number, or may erroneously input the product number.

  The present invention has been made in view of the above-described conventional situation, and an object to be solved is to provide a quality data management system capable of efficiently performing quality data management for each product.

  The quality data management system of the present invention includes a plurality of actual product forms, a plurality of reading devices, and a storage device. Each item slip is given a vote number. Each product slip moves through a plurality of processes together with the product, and then returns to the top process which is the top of those processes and circulates. Each reading device reads the vote number of the actual product slip in each process. The storage device stores the vote number associated with the first process and the individual identification information of the product. Further, the storage device stores the quality data in association with the individual identification information associated with the vote number read by the reading device in each step.

  In this quality data management system, individual identification information is associated with a vote number of an actual product slip that moves with a product through a plurality of processes. For this reason, in this quality data management system, the reading device reads the vote number in each step, so that the storage device can store the quality data in association with the individual identification information. In addition, since this quality data management system circulates and uses a plurality of product tags, it is possible to eliminate the trouble of printing individual identification information for each product on the product certificate, and to manage quality data relatively. This can be done at low cost. In addition, this quality data management system can shorten the reading time of the reading device and reduce erroneous recognition if the vote number is simplified.

  Therefore, the quality data management system of the present invention can efficiently perform quality data management for each product.

  In addition, this quality data management system stores quality data associated with individual identification information in the storage device even if the actual product slip is damaged or lost. If you create a new password and attach it to the product, you can continue to operate the system.

  In addition, since this quality data management system circulates multiple product slips, it collects the history of the pass of each product slip in each process, leads the turn rate of the product slip, and leads that the product slip moves through multiple processes. By analyzing time etc., it can be used for logistics improvement.

  In addition, this quality data management system can analyze the stock status from the number of actual product slips that are moving through each process. For this reason, this quality data management system can be utilized for inventory reduction and optimization of production instructions.

  In the quality data management system of the present invention, the product may be a core used for casting. The core is manufactured by being executed in the order of a firing process, a deburring correction process, an assembly process, a paste drying process, a coating process, a coating drying process, and an inspection process, and is stored in a mold. The actual product slip can be circulated by moving a plurality of steps after the firing step.

  Since the core is thin cylindrical sand and has a limited printing space, a high technique is required to attach the individual identification information directly to the core, which may increase the cost. In addition, when the paint is applied in the coating process, the individual identification information printed on the core may not be recognized. Further, since the core is dried at a high temperature in the paste drying process and the coating mold drying process, an IC tag having low heat resistance cannot be attached. For such a core, the quality data management system reads the identification number associated with the vote number by reading the vote number of the actual product slip without reading the identification information on the core. The quality data can be stored in association with. In addition, this quality data management system can collect each quality data without burdening the operator.

  In the quality data management system of the present invention, the individual identification information can be integrally attached to the product. In this case, even if the actual product slip is damaged or lost, the actual product slip of the same description newly created based on the individual identification information attached to the product can be attached to the product.

  Embodiments 1 and 2 embodying the quality data management system of the present invention will be described with reference to the drawings.

<Embodiment 1>
The quality data management system of Embodiment 1 is used for the core line 1 in a casting facility having a core line 1, a molding line, a melting line 5, a finishing inspection line 7, and a processing line 9, as shown in FIG. The As shown in FIGS. 2 and 3, the core line 1 includes a firing process, a deburring correction process, an assembly process, a paste drying process, a coating process, a coating drying process, and an inspection process. In the firing step, sand is poured into a mold and fired to produce a core body. The core body is a main member constituting the core. The core body is placed on a pallet having heat resistance one by one and moves through each process. The deburring correction process removes burrs from the core body. In the assembly process, the core is assembled by gluing small parts to the core body. That is, the core is composed of a core body and small parts. In the paste drying step, the assembled core is placed in a drying furnace to dry the paste at a high temperature. In the coating process, the core is immersed in a solution stretched in a tank and a paint for preventing seizure is applied to the surface. In the coating mold drying process, the core after applying the paint for preventing seizure is placed in a drying furnace and dried at a high temperature. In the inspection process, a final inspection of the core is performed, and pass / fail is determined. Since the core line 1 has different production capacities in each process, batch production is performed in each process.

  In the baking process, as shown in FIGS. 2 to 4, a computer 10 having a touch panel 10 </ b> A and a two-dimensional barcode reader 20 as a reading device are installed. In the firing process, each time the core body placed on the pallet is fired and generated, the operator operates the touch panel 10A and the core serial number (Z-15X301) which is individual identification information for each core body. -1-001) is generated by the computer 10. The core serial number includes consecutive serial numbers (-001, -002, ...). That is, a different core serial number is generated for each core body. The core body may not have a core serial number. However, as shown in FIG. 7, the core body is provided in the core body 2, and the core is formed in a cavity formed in a lower mold and an upper mold of the mold. The core serial number may be given to the baseboard 2A or the like, which is a portion where the core is supported when placed on the core.

  A predetermined number of the firing process actual product forms 30 which are actual product forms are prepared and provided in the actual product form post 31 installed in the firing process. As shown in FIG. 4, these firing process actual product forms 30 include a vote number (X00001), a matrix type two-dimensional code 30A, a product number (XX151-55X12-XHT), a shelf number (Y001), and a process (firing → collection). (→ Parts storage) is printed. The vote number specifies the firing process actual product form 30 itself, and includes consecutive serial numbers (00001,00002,...). That is, a different vote number is printed for each firing process actual product slip 30. The matrix type two-dimensional code 30 </ b> A encodes information such as a vote number printed on the firing process actual product form 30. The product number is the product number of the core body produced in the firing process. The shelf number indicates the shelf number on which the core body before firing was temporarily placed. The process indicates a process in which the firing process actual product form 30 moves together with the core body. In other words, this firing process actual product form 30 is taken out of the actual product post 31 after the core body is fired and generated, and placed on the upper surface of the pallet. Together with the core body, the firing process, the deburring correction process, and Move the parts store.

  In the firing process, the operator uses the two-dimensional barcode reader 20 after operating the touch panel 10A, that is, after a different core serial number (Z-15X301-1-001) is generated for each core body. Then, the matrix type two-dimensional code 30 </ b> A of the firing process actual product slip 30 placed on the pallet is read. Then, the computer 10 associates the vote number (X00001) of the firing process actual product form 30 printed on the firing process actual product form 30 with the core serial number (Z-15X301-1-001). Information associated with the vote number and the core serial number is stored in the database server 40 which is a storage device.

  In addition, in the firing process, for each core body produced, the core body quality data (for example, the material of the sand poured into the mold, the firing temperature, etc.) affecting the core quality is the core serial number (Z -15X301-1-001) and stored in the database server 40. These quality data are automatically input by a sensor, or are input by an operator operating the touch panel 10A, and are stored in the database server 40. This quality data can be used for defect tracking and defect analysis.

  Also in the deburring correction process, as shown in FIG. 2, a computer 10 having a touch panel 10A and a two-dimensional barcode reader 20 are installed. The core body is sent from the firing process to the deburring correction process while being placed on the pallet. Since the firing process actual product form 30 is placed on the upper surface of the pallet, it moves to the deburring correction process together with the core body.

  In the deburring correction process, the operator uses the two-dimensional bar code reader 20 to read the matrix type two-dimensional code 30 </ b> A of the firing process actual product slip 30 placed on the pallet. Then, the computer 10 obtains the vote number (X00001) of the firing process actual product form 30 and, based on this vote number, the core serial number (Z-15X301-1-) placed on the pallet. 001) from the database server 40. As a result, the core body from which the burrs have been removed in the deburring correction process can be associated with the core serial number.

  Then, in the deburring correction process, the core body quality data (for example, the presence or absence of a chip or a crack) that affects the core quality is stored in the database server 40 in association with the core serial number for each core body. Is done. These quality data are input by the operator operating the touch panel 10 </ b> A and stored in the database server 40. This quality data can also be used for defect tracking and defect analysis. The core body that has completed the deburring correction process is temporarily stored in the parts warehouse while being placed on the pallet.

  When the core body placed on the pallet from the parts store is moved to the assembly process, the firing process product form 30 is replaced with the assembly process product form 50 as shown in FIGS. 2, 3, and 6. . After being replaced with the assembly process actual product form 50, the firing process actual product form 30 is removed from the pallet and returned to the actual product form post 31 provided in the firing process. As described above, after the core body is baked and generated in the order returned to the actual product post 31, the actual product post 30 returned to the actual product post 31 provided in the firing process is returned to the actual product post 30. 31 and is placed on the upper surface of the pallet on which the core body is placed. In this way, the firing process actual product form 30 circulates through the firing process, the deburring correction process, and the parts warehouse. Here, the firing step corresponds to the leading step.

  As shown in FIG. 3, a predetermined number of assembling process actual product forms 50 are prepared and provided in the actual product form post 51 installed in the assembly process. As shown in FIG. 6, these assembly process actual product forms 50 have a form number (Y00001), a matrix type two-dimensional code 50A, an ASSY product number (XX151-55X12-XNK), a body product number (XX151-55X12-XHT), and a shelf number. A (X001), part number (XX151-41X12-XST), shelf number B (Y001), and process (assembly → glue drying → coating drying → inspection → completed place → molding) are printed. The vote number identifies the assembly process actual product slip 50 itself, and includes consecutive serial numbers (00001, 00002,...). That is, a different vote number is printed for each assembly process actual product slip 50. The matrix type two-dimensional code 50 </ b> A codes information such as a vote number printed on the assembly process actual product slip 50. The ASSY product number is the product number of the core that is assembled by gluing small parts to the core body in the assembly process. The body part number is the part number of the core body. The shelf number A is the shelf number on which the core body is temporarily placed. The part number is the number of the small part that is glued to the core body. The shelf number B is the shelf number where the small parts are temporarily placed. The process indicates a process in which the assembly process actual product slip 50 moves together with the core. That is, as shown in FIGS. 2 and 3, this assembly process actual product slip 50 is placed on the upper surface of the pallet on which the core assembled by gluing small parts to the core body in the assembly process is placed, The assembly process, paste drying process, coating mold process, coating mold drying process, inspection process, finished product storage area, and molding line core housing process are moved together with the core.

  As shown in FIG. 6, the replacement of the firing process actual item 30 and the assembly process actual item 50 is performed by using a handy terminal computer 60 capable of reading the matrix type two-dimensional codes 30A and 50A as described below. Is called.

  First, the operator uses the handy terminal computer 60 to read the matrix type two-dimensional code 30 </ b> A of the firing process actual product slip 30 placed on the pallet on which the core body is placed. Then, the handy terminal computer 60 obtains the vote number (X00001) of the in-process card 30 of the firing process, and obtains the core serial number (Z-15X301-1-001) from the database server 40 based on the obtained vote number. To do.

  Next, the operator uses the handy terminal computer 60 to read the matrix type two-dimensional code 50 </ b> A of the assembly process actual product slip 50. Then, the handy terminal computer 60 obtains the vote number (Y00001) of the assembly process actual product slip 50 and associates this vote number with the core serial number (Z-15X301-1-001). Information that associates the vote number with the core serial number is stored in the database server 40. In this way, the firing process actual product slip 30 and the assembly process actual product slip 50 are replaced. The replaced assembly process product form 50 is placed on the pallet on which the firing process product form 30 has been placed.

  In each of the assembly process, the paste drying process, the coating process, the coating drying process, and the inspection process, the computer 10 having the touch panel 10A and the two-dimensional barcode reader 20 are installed. The coating process and the coating drying process are provided with a common touch panel 10A, and are shared by these processes.

  In each of the assembly process, glue drying process, coating mold process, coating mold drying process, and inspection process, the operator is placed on the pallet using the two-dimensional barcode reader 20, as shown in FIG. The matrix type two-dimensional code 50A of the assembly process actual product form 50 is read. Then, the computer 10 obtains the vote number (Y00001) of the assembly process actual product slip 50, and based on this vote number, the computer 10 detects the core serial number (Z-15X301-1) placed on the pallet. -001) from the database server 40. As a result, the core body of each process can be associated with the core serial number.

  And in each process of the assembly process, paste drying process, coating mold process, coating mold drying process, and inspection process, quality data that affects the quality of the core (for example, the presence or absence of chips or cracks in each process, glue drying process The temperature of the drying furnace in the coating process, the composition of the solution in the coating process, the temperature of the drying furnace in the coating drying process, etc.) are associated with the core serial number (Z-15X301-1-001) for each core. Is remembered. These quality data are automatically input by a sensor, or are input by an operator operating the touch panel 10A, and are stored in the database server 40. These quality data can also be used for defect tracking and defect analysis.

  The core that has completed the inspection process is temporarily stored in the finished product storage area while being placed on the pallet. Thereafter, the core is transported to the core housing step of the molding line while being placed on the pallet, and is placed in a cavity formed in the lower mold and the upper mold of the mold. At this time, the operator uses the two-dimensional barcode reader 20 to read the matrix type two-dimensional code 50 </ b> A of the assembly process actual product slip 50 placed on the pallet. As a result, information about which core is contained in the mold is collected and stored in the database 40. Also, the assembly process actual product form 50 placed on the pallet is removed from the pallet after the operator reads the matrix type two-dimensional code 50A using the two-dimensional barcode reader 20, and is provided for the assembly process. The actual item slip post 51 is returned to. The assembly process actual product slip 50 returned to the actual product slip post 51 provided in the assembly process is used to replace the firing process actual product slip 30 in the order returned to the actual product slip post, and the core is loaded. It is placed on the upper surface of the placed pallet. In this way, the assembly process actual product slip 50 circulates through the assembly process, the paste drying process, the coating process, the coating mold drying process, the inspection process, the finished product storage area, and the core forming process of the molding line. Here, the assembly process corresponds to the top process.

  As described above, the quality data management system according to the first embodiment includes a plurality of baking process actual product forms 30, a plurality of assembly process actual product forms 50, a plurality of two-dimensional barcode readers 20 provided in each process, and a database server 40. I have. Each firing process actual product slip 30 and each assembly process actual product slip 50 are given a vote number. Each of the firing process actual product forms 30 is returned to the firing process via the actual product form post 31 provided in the firing process after moving the firing process, the deburring correction process, and the parts warehouse together with the core body. In this manner, each firing process actual product form 30 circulates through the firing process, the deburring correction process, and the parts warehouse. In addition, each assembling process actual product slip 50 is moved to the assembly process after the assembly process, the paste drying process, the coating process, the coating drying process, the inspection process, the finished product storage area, and the molding process core housing process together with the core. The product is returned to the assembling process via a product tag post 51 provided in the process. In this way, the assembly process actual product slip 50 circulates through the assembly process, the paste drying process, the coating process, the coating mold drying process, the inspection process, the finished product storage area, and the core forming process of the molding line. Each two-dimensional bar code reader 20 reads the vote number of the firing process actual product form 30 or the assembly process actual product form 50 in each process. The database server 40 stores the vote number and the core serial number associated with the core body in the firing process or the assembly process as the first process. In addition, the database server 40 stores the quality data in association with the core serial number associated with the vote number read by the two-dimensional barcode reader 20 in each process.

  In this quality data management system, the core serial number is associated with the vote number of the firing process actual product slip 30 or the assembly process actual product slip 50 that moves a plurality of processes together with the core body or the core. Therefore, in this quality data management system, the database server 40 can store the quality data in association with the core serial number when the two-dimensional barcode reader 20 reads the vote number in each step. In addition, since this quality data management system circulates and uses a plurality of firing process product forms 30 or assembly process product forms 50, different core serial numbers for each core body or core are used in the firing process product form 30 or It is possible to eliminate the trouble of printing on the assembly process actual product form 50 and to manage quality data at a relatively low cost. Further, this quality data management system can shorten the reading time of the two-dimensional barcode reader 20 or reduce erroneous recognition by simplifying the vote number.

  Therefore, the quality data management system of Embodiment 1 can efficiently perform quality data management for each product.

  Further, this quality data management system stores the quality data associated with the core serial number in the database server 40 even if the firing process actual item 30 or the assembly process actual item 50 is damaged or lost. Therefore, if a new firing process product tag 30 or assembly process product certificate 50 printed with the same content is newly created and placed on the pallet on which the core body or core is placed, the system can be continued. It can be operated.

  In addition, since this quality data management system circulates a plurality of firing process actual product forms 30 or a plurality of assembly process actual product forms 50, the passing history of these actual product forms in each process is collected, and the rotation rate of the actual product forms is collected. It can also be used for logistics improvement by analyzing the lead time or the like when the actual product slip moves through a plurality of processes.

  In addition, this quality data management system can analyze the stock status from the transition of the firing process actual product slip 30 or the assembly process actual product slip 50 that is moving through each process. For this reason, this quality data management system can be utilized for inventory reduction and optimization of production instructions.

  This quality data management system is used to manufacture cores used for casting. The core is manufactured by being executed in the order of a firing process, a deburring correction process, an assembly process, a paste drying process, a coating process, a coating drying process, and an inspection process, and is stored in a mold. The firing process item tag 30 circulates through the firing process, the deburring correction process, and the parts warehouse. The assembly process actual product form 50 circulates through an assembly process, a paste drying process, a coating process, a coating drying process, an inspection process, a finished product storage area, and a core storage process of a molding line.

  Since the core is thin cylindrical sand and has a limited printing space, a high technique is required to attach the core serial number directly to the core, which may increase the cost. In addition, if a paint is applied in the coating process, the core serial number printed directly on the core may not be recognized. Further, since the core is dried at a high temperature in the paste drying process and the coating mold drying process, an IC tag having low heat resistance cannot be attached. For such a core, this quality data management system reads the vote number of the firing process actual product slip 30 or the assembly process actual product slip 50 with a reader without printing the core serial number on the core. The quality data can be stored in association with the core serial number associated with these vote numbers. In addition, this quality data management system can collect each quality data without burdening the operator.

  Further, in this quality data management system, if the core serial number is integrally attached to the core body, even if the firing process actual product slip 30 or the assembly process actual product slip 50 is damaged or lost, the core Correctly place the firing process actual item sheet 30 or assembly process actual item sheet 50 newly created by relying on the core serial number attached to the main body on the pallet on which the core main body or core is mounted. You can fix it.

<Embodiment 2>
The quality data management system according to the second embodiment combines a plurality of semi-finished cores (the assembly process and the paste drying process are performed so that the core body and the small parts are integrated) into a mold. The point which forms the core arrange | positioned in the cavity formed in the lower mold | type and upper mold | type is different from Embodiment 1. FIG. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  In this quality data management system, when the cores are formed by combining the cores of two semi-finished products, as shown in FIG. To be created.

  First, the operator uses the two-dimensional bar code reader 20 provided for the assembly process to form a matrix type of assembly process actual product forms 53 and 55 placed on the pallet on which the core of the semi-finished product is placed. The two-dimensional codes 53A and 55A are read. Then, the computer 10 acquires the respective vote numbers (Y00001, Y00002), and the core serial numbers (Z-15X301-1-001, Z-15X301-1-002) associated with these vote numbers are stored in the database server 40. Get from. The same items as the assembly process actual product form 50 described above are printed in the assembly process actual product forms 53 and 55 of the core of the semi-finished product, but “assembly → glue drying → assembly” is printed in the process column. . In other words, it is shown that the assembly process actual product forms 53 and 55 move to the assembly process in order to unite after moving the assembly process and the paste drying process together with the core of the semi-finished product.

  Next, the operator uses the two-dimensional barcode reader 20 to read the matrix type two-dimensional code 57 </ b> A of the assembly process actual product form 57 after the combination. Then, the computer 10 obtains the vote number (Y00010) of the assembly process actual product form 57 after the merge, and newly generates the core serial number (Z-15X301-1-001-U). Thereafter, information in which the acquired vote number (Y00010) is associated with the new core serial number (Z-15X301-1-001-U) is stored in the database server 40. The core serial number (Z-15X301-1-001, Z-15X301-1-002) of each core of the semi-finished product and the new core serial number (Z-15X301-1-001- U) and stored in the database server 40. The assembly process actual product form 57 of the core after the combination is printed with the form number, matrix type two-dimensional code 57A, ASSY product number, and process.

  A predetermined number of assembling process actual product forms 57 after the combination are prepared and provided in an actual product post 51 installed in the assembly process. As described above, the assembly process actual product form 57 is placed on the upper surface of the pallet on which the combined core is placed, and together with the core, the assembly process, the glue drying process, the coating process, the coating mold drying process, and the inspection process. Move the core storage process of the finished product storage and molding line. The assembly process actual product form 57 is removed from the pallet when the combined core is placed in the cavity formed in the lower mold and upper mold of the mold, and the actual product post 51 provided in the assembly process. Returned to The assembly process actual product form 57 returned to the actual product form post 51 provided in the assembly process forms the core by combining the cores of the semi-finished products in the order returned to the actual product form post 51 as described above. Used when In this way, the assembly process actual product form 57 also circulates through the assembly process, the paste drying process, the coating process, the coating drying process, the inspection process, the finished product storage area, and the molding line core housing process. Here, the assembly process corresponds to the top process.

  As described above, in the quality data management system according to the second embodiment, a new core serial number is associated with the vote number of the assembly process actual product slip 57 in which a plurality of processes are moved together with the core after being combined. Therefore, in this quality data management system, the database server 40 can store the quality data in association with the core serial number when the two-dimensional barcode reader 20 reads the vote number in each step. In addition, since this quality data management system circulates and uses a plurality of post-combination assembly process actual product forms 57, there is a trouble of printing a different core serial number on the assembly process actual product form 57 for each core after integration. The quality data can be managed at a relatively low cost. Further, this quality data management system can shorten the reading time of the two-dimensional barcode reader 20 or reduce erroneous recognition by simplifying the vote number.
