Description

The present invention, production control system, production process management apparatus, and a production control method.

Conventionally, various techniques for managing information on the production of a production target in each process have been proposed for a production target produced in a production factory through a plurality of processes. As an example, there is a technique related to traceability that records information such as parts and raw materials used in each process and makes it possible to trace the production history.

For example, Patent Document 1 below discloses a technique that enables traceability by managing component information of each component using an IC card when each component is transported between processes. In this technique, each process is provided with a terminal device that reads the component information stored in the IC card and writes the component information to the IC card. The terminal device reads the parts information related to the previous process from the IC card when the parts are carried from the previous process to the own process. Further, the terminal device writes the component information related to the own process on the IC card when the component is carried out from the own process to the subsequent process. The component information read from the IC card and the component information written to the IC card in each process are managed by the trace terminal device.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
The present invention relates to a production process management system that manages each process of a production line to be produced by using information read from a recording medium.

The recording medium is, for example, an RFID (Radio Frequency Identifier) tag, a two-dimensional code, a one-dimensional code, or the like. The two-dimensional code is, for example, a two-dimensional bar code. The one-dimensional code is, for example, a one-dimensional bar code. In the following, an example in which an RFID tag is used will be described as an example.

The recording medium is provided on various media. The recording medium is printed on a medium such as paper, plastic, or a thin iron plate. The shape of the medium is, for example, a card shape. The type and shape of the medium on which the recording medium is printed are not particularly limited as long as the recording medium can be printed. In the following, as an example, an example in which a recording medium (hereinafter, also referred to as “RFID card”) in which an RFID tag is printed on card-shaped paper is used will be described.

The present invention can be applied to the production lines of various production plants. The field of the production factory is not particularly limited. The fields of factories include, for example, the fields of automobiles, printing, papermaking, chemistry, machinery, steel, construction, food, pharmaceuticals, home appliances and the like. Production line processes include, for example, the arrival process in which parts and raw materials are delivered, the processing process in which parts and raw materials are processed, the assembly process in which processed parts are assembled, the inspection process in which assembled products are inspected, and the products after inspection. There is a shipping process for shipping. Each process can be divided into more detailed processes according to the production target.

In the production line of a production factory, for example, production control is performed by a Kanban method. Kanban is a production instruction sheet. In the Kanban, for example, work instructions such as a part name, a quantity, and a delivery time of a part are described. Generally, a thin iron plate, plastic, paper or the like is used for Kanban. In addition, there are two types of Kanban, a "pick-up Kanban" for delivery management and a "device Kanban" for production control. The Kanban can be replaced by the RFID card used in the present invention. Therefore, the present invention can be applied to a production factory in which production control is performed by the Kanban method. The present invention can also be applied to a production factory in which production control is performed without using the Kanban method.

In the following, management of the cutting process in an automobile production factory will be described as an example. The production target of the entire production plant is automobiles. The production target in the cutting process is automobile seat parts. Here, the seat is a seat on which a passenger of an automobile can be seated. Further, the seat part is, for example, a part used on the surface of the seat, and the raw material is leather. The raw material is not limited to leather, and may be cloth, synthetic leather, fabric, or the like.

In the cutting process of the present embodiment, for example, a part of the seat parts of an automobile is cut from the raw material of the raw material. Here, the original fabric is a state in which a sheet-like object having a wide surface is wound. A part of the original fabric is pulled out and cut, and the remaining rolled material is also the original fabric. Specifically, first, a part of the leather drawn from the original fabric is cut. A part of the leather cut from the raw fabric is also referred to as a "seat member" below. Next, the sheet component is cut from the sheet member according to the shape.

<1. Production process management system configuration>
First, the configuration of the production process management system according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing an example of the configuration of the production process management system according to the present embodiment. As shown in FIG. 1, the production process management system 1 includes an RFID card issuing PC (Personal Computer) 10, an RFID card issuing printer 20, a stand-type RFID reader 30-1 to 30-n, a production process management server 40, and a display. The device 50 and the sensor device 60 are included. Each device included in the production process management system 1 is communicably connected to each other via a network 70.

The RFID card issuing PC 10 is a terminal operated by an operator to issue an RFID card. The RFID card issuing printer 20 is a printer that prints RFID cards. The RFID card issuing PC 10 causes the RFID card issuing printer 20 to print the RFID card based on the information input by the operator. The RFID card is given a card ID, which is identification information unique to each RFID card.

The card ID of this embodiment is used as identification information (first identification information) of a processing target, which is an object to be processed in each process. Therefore, the processing target is associated with the card ID. The processing target includes a raw material and a processed product obtained by processing the raw material. The raw material to be processed is, for example, leather. In the present embodiment, leather, which is a raw material, is rolled into a raw fabric, and the raw fabric is cut (processed). Therefore, in the cutting process, the raw material to be processed includes the raw material. The work piece to be processed is, for example, a sheet part. The sheet parts are sewn (processed) on the surface of the sheet, for example, in a process after the cutting process.

The RFID card to which the work piece is associated is also referred to as a "device card" below. The gimmick card has the same role as the gimmick Kanban in the Kanban system. That is, the gimmick card is used for production control of the processed product. A different card ID is assigned to the device card for each work piece.

RFID cards associated with raw materials are also referred to below as "pick-up cards". The pick-up card has the same role as the pick-up Kanban in the Kanban system. That is, the pick-up card is used for managing the delivery of raw materials. A different card ID is assigned to the pick-up card for each raw material.

Hereinafter, an example in which two types of cards, a take-back card and a gimmick card, are used as RFID cards will be described. The type of RFID card is not limited to this example. Further, the type of RFID card used in the production process management system 1 is not limited to this example.

Here, the RFID card issued by the RFID card issuing printer 20 will be described with reference to FIG. FIG. 2 is a diagram showing an example of the RFID card 22 according to the present embodiment.

As shown in FIG. 2, the RFID card 22 has card information 24 and an RFID tag 26. The card information 24 and the RFID tag 26 are printed on card-shaped paper by the RFID card issuing printer 20. When the RFID card 22 is a device card, information about the work piece is printed as the card information 24. When the RFID card 22 is a pick-up card, information about raw materials is printed as card information 24.

The stand-type RFID reader 30-1 to 30-n (n is a natural number) is a reading device having a function of performing processing based on the information read from the RFID card 22. In the following description, when each of the stand type RFID readers 30-1 to 30-n is not distinguished, it is referred to as a stand type RFID reader 30. The stand-type RFID reader 30 is provided for each process of the production line to be produced. Further, a plurality of stand-type RFID readers 30 may be provided in each step. The natural number n is a value indicating the number of stand-type RFID readers 30 provided in each process. A terminal ID (second identification information), which is identification information unique to each stand-type RFID reader 30, is assigned to the stand-type RFID readers 30-1 to 30-n.

First, the hardware configuration of the stand-type RFID reader 30 will be described with reference to FIG. FIG. 3 is a diagram showing an example of the hardware configuration of the stand-type RFID reader 30 according to the present embodiment. As shown in FIG. 3, the stand-type RFID reader 30 includes a main body 31, a support 32, a display device 33, a connecting member 34, an RFID reader 35, a card slot 36, and a control device 37.

As shown in FIG. 3, the main body 31 and the display device 33 are connected to each other via a support column 32. Further, the support column 32 and the RFID reader 35 are connected via a connecting member 34. The card slot 36 is connected to the RFID reader 35. The control device 37 is provided inside the main body 31.

The main body 31 is a housing capable of storing the control device 37. The control device 37 is a PC having a size that can be stored in the main body 31. The PC is, for example, an edge PC.

The display device 33 is realized by, for example, a monitor. Further, the display device 33 may be realized by a display device having a touch panel. The touch panel allows the operator to perform an input operation on the display device 33. Further, the display device 33 may be a display device having a speaker and capable of outputting audio. As a result, the display device 33 can also output information by voice. The stand-type RFID reader 30 may be provided with an audio output device independent of the display device 33.

The RFID reader 35 reads the card ID from the RFID tag of the RFID card 22 that has been moved into a predetermined reading range. The RFID card 22 is moved (first operation) from outside the predetermined reading range to the inside by the operator. Further, the RFID card 22 can be moved (second operation) from within the predetermined reading range to the outside by the operator. The predetermined reading range in this embodiment is, for example, the inside of the card slot 36. Therefore, when the RFID reader 35 is made to read the card ID, the operator performs an operation of inserting the RFID card 22 into the card slot 36 (hereinafter, also referred to as “slide-in”) as the first operation. On the other hand, when the reading of the card ID by the RFID reader 35 is completed, the operator performs an operation of removing the RFID card 22 from the card slot 36 (hereinafter, also referred to as “slide-out”) as a second operation. In the following, operations including slide-in and slide-out to RFID card 22 are also referred to as “card operations”.

The card slot 36 has a structure that allows the stand-type RFID reader 30 to continue reading with respect to the RFID card 22 and maintains the posture of the RFID card 22. As shown in FIG. 3, in the card slot 36, for example, a box that is partially opened and can store the RFID card 22 is used. The shape, size, and other configurations of the card slot 36 are not particularly limited as long as the stand-type RFID reader 30 can read the card ID from at least one RFID card 22.

The configuration of the stand-type RFID reader 30 is not limited to the example shown in FIG. However, it is desirable that the stand-type RFID reader 30 is provided at least without being fixed to the floor, wall, or the like. Thereby, for example, when the layout of the production line of the production factory is changed, the operator can easily move the stand type RFID reader 30.

Subsequently, the functional configuration of the stand-type RFID reader 30 will be described with reference to FIG. As shown in FIG. 1, the stand-type RFID reader 30 includes a reading unit 310, a control unit 320, a communication unit 330 (first communication unit), and an output unit 340.

The reading unit 310 has a function of reading information from the RFID card 22 stored in the card slot 36. This function is realized by, for example, an RFID reader 35. The reading unit 310 reads, for example, the card ID of the RFID card 22 slid into the card slot 36 by the operator at predetermined time intervals. The time set at a predetermined time interval is not particularly limited, and an arbitrary time may be set. After reading the card ID, the reading unit 310 outputs the read card ID to the control unit 320.

The control unit 320 has a function of controlling the overall operation of the stand-type RFID reader 30. The function is realized by, for example, the control device 37. The control unit 320 controls the transmission of information in the communication unit 330. For example, when a card ID is input from the reading unit 310, the control unit 320 causes the communication unit 330 to transmit the terminal ID of the stand-type RFID reader 30 and the input card ID. Note that the control unit 320 may cause the communication unit 330 to transmit information at predetermined time intervals regardless of whether or not the card ID is input from the reading unit 310. In this case, the control unit 320 causes the communication unit 330 to transmit at least the terminal ID at predetermined time intervals.

Further, the control unit 320 controls the output in the output unit 340. For example, the control unit 320 causes the output unit 340 to output the information received by the communication unit 330 from the production process management server 40.

The communication unit 330 has a function of transmitting information input from the control unit 320. For example, the communication unit 330 transmits the card ID and the terminal ID input from the control unit 320 to the production process management server 40. Specifically, when the card ID and the terminal ID are input from the control unit 320, the communication unit 330 transmits the input card ID and the terminal ID to the production process management server 40. When only the terminal ID is input from the control unit 320, the communication unit 330 may transmit only the terminal ID to the production process management server 40.

Further, the communication unit 330 has a function of receiving information transmitted from the production process management server 40. When the information is received from the production process management server 40, the communication unit 330 outputs the received information to the control unit 320.

The output unit 340 has a function of outputting information input from the control unit 320. The function is realized by, for example, the display device 33. In this case, the output unit 340 converts the information input from the control unit 320 into an image and displays it. When the stand-type RFID reader 30 has a configuration capable of outputting voice, the output unit 340 may convert the information input from the control unit 320 into voice and output it.

The production process management server 40 is a production process management device having a function of managing information related to the production process. In order to realize this function, the production process management server 40 includes a communication unit 410 (second communication unit), a control unit 420, and a storage unit 430, as shown in FIG.

The communication unit 410 has a function of transmitting and receiving various information. For example, the communication unit 410 receives the card ID and the terminal ID transmitted from the stand-type RFID reader 30. The communication unit 410 outputs the card ID and the terminal ID received from the stand-type RFID reader 30 to the control unit 420. When only the terminal ID is received from the stand-type RFID reader 30, the communication unit 410 may output only the terminal ID to the control unit 420.

The control unit 420 has a function of controlling the overall operation of the production process management server 40. This function is realized, for example, by causing a CPU (Central Processing Unit) provided as hardware in the production process management server 40 to execute a program. In order to realize this function, the control unit 420 includes a detection unit 422, a determination unit 424, a data processing unit 426, and an output processing unit 428, as shown in FIG.

The detection unit 422 has a function of detecting information regarding the card ID received by the communication unit 410. For example, the detection unit 422 detects whether or not the information received by the communication unit 410 includes the card ID. When the card ID is detected, the detection unit 422 outputs the detection result including the detected card ID and the terminal ID to the determination unit 424. On the other hand, when the card ID is not detected, the detection unit 422 outputs the detection result including only the terminal ID to the determination unit 424.

The determination unit 424 has a function of determining a card operation performed on the RFID card 22 by the operator based on the detection result by the detection unit 422. It is assumed that the detection result at the time of reception this time includes a card ID that has not been received at the time of the previous reception in the communication unit 410. This means that the RFID card 22 has been moved from outside the predetermined reading range to the inside, so that the card ID is newly acquired. Therefore, the determination unit 424 determines that the slide-in has been performed on the RFID card 22 corresponding to the card ID received at the time of reception this time.

On the other hand, it is assumed that the detection result at the time of receiving this time does not include the card ID received at the time of the previous reception in the communication unit 410. This means that the acquisition of the card ID has been completed because the RFID card 22 has been moved out of the predetermined reading range. Therefore, the determination unit 424 determines that the slide-out has been performed on the RFID card 22 corresponding to the card ID that has not been received at the time of reception this time. After the determination process, the determination unit 424 outputs the determination result to the data processing unit 426.

The data processing unit 426 executes processing according to the combination of the processing target associated with the card ID and the content of the production process in the process associated with the terminal ID. The data processing unit 426 identifies the combination and determines the process to be executed based on the card operation performed when the operator performs the card operation on the RFID card 22.

In the present embodiment, the information regarding the processing target is stored in the card information database of the storage unit 430 in association with the card ID. Therefore, the data processing unit 426 refers to the card information database using the card ID as a search key, and specifies the processing target.

Here, the card information will be described with reference to FIG. FIG. 4 is a diagram showing an example of the configuration of the card information table in the card information database according to the present embodiment. As shown in FIG. 4, the record in the card information table includes a card ID, a card type, and a processing target. The information included in the record of the card information table is not limited to this example.

The card ID indicates the identification information of the RFID card 22. The card type indicates the type of RFID card 22. The processing target indicates a processing target associated with the RFID card 22.

For example, in the first record where the card ID is "101", it is stored that the card type is "pick up" and the processing target is "raw fabric AAA". This indicates that the RFID card 22 having the card ID of 101 is a take-back card used for delivery management (including inventory management) of the original fabric AAA. Similarly, the RFID card 22 having the card ID of 102 in the second record indicates that it is a take-back card used for delivery management of the original fabric BBB. Further, the RFID card 22 having the card ID of 103 in the third record indicates that it is a take-back card used for delivery management of the original fabric CCC.

In the fourth record where the card ID is "104", it is stored that the card type is "device" and the processing target is "sheet part DDD". This indicates that the RFID card 22 having the card ID of 104 is a device card used for production management (including performance management) of the sheet component DDD. Similarly, the RFID card 22 having a card ID of 105 in the fifth record indicates that it is a device card used for production control of the sheet component EEE. Further, the RFID card 22 having the card ID of 106 in the sixth record indicates that it is a device card used for production control of the sheet component FFF.

When the processing target is a raw material and the terminal ID corresponds to a production process using the raw material stored as inventory, the data processing unit 426 executes processing related to inventory management of the raw material indicated by the card ID received together with the terminal ID. To do. For example, the data processing unit 426 executes an update process of inventory management information of raw materials corresponding to the RFID card 22 on which the card operation has been performed. The production process using the raw materials stored as inventory is, for example, a cutting process in which a part of the raw material is pulled out and cut. In the present embodiment, the inventory management information is stored in the inventory management information database of the storage unit 430.

Here, inventory management information will be described with reference to FIG. FIG. 5 is a diagram showing an example of the configuration of the inventory management information table in the inventory management information database according to the present embodiment. In the following, an example in which the raw material is leather and the inventory of the leather is managed in units of raw materials will be described. As shown in FIG. 5, the record of the inventory management information table includes the name of the original fabric, the location of the original fabric, the number of stocks, the length of the original fabric, and the inventory status. The information included in the record of the inventory management information table is not limited to such an example.

The original fabric name indicates the name of the original fabric in stock. The location of the original fabric indicates the storage place of the original fabric in stock. The number of stocks indicates the number of raw fabrics in stock. The length of the original fabric indicates the total length of each length of the original fabric 1 to the original fabric n and the length of each of the original fabric 1 to the original fabric n. N of the original fabric n is the number of stocks. The stock status indicates the stock status of the original fabric.

For example, in the first record where the name of the original fabric is "AAA", it is remembered that the location of the original fabric is "GGG". This indicates that "Original AAA" is placed in "Original yard GGG".

Further, in the first record, it is remembered that the number of "raw fabric AAA" in stock is "1", the length of the stock fabric 1 is "90 m", and the total length is "90 m". This is because the number of original fabrics AAA in stock at the original fabric AAA is one, the length of the original fabric 1 in the original fabric AAA is 90 m, and the stock of the original fabric AAA is 90 m. It shows that the total of all lengths is 90m.

Further, in the first record, it is stored that the inventory status is "waiting for arrival". This indicates that the original fabric AAA has been ordered and is waiting for its arrival.

It is remembered that the location of the original tan is "HHH" in the second record where the original tan name is "original tan BBB". This indicates that the "original tan BBB" is placed in the "original tanning ground HHH".

In the second record, the number of "raw fabric BBB" in stock is "2", the length of the stock fabric 1 is "100m", the length of the stock fabric 2 is "90m", and the total length is " It is remembered that it is "190m". This is because the number of raw fabrics BBB in stock at the original fabric HHH is two, the length of the original fabric 1 in the stock of the original fabric BBB is 100 m, and the length of the original fabric 2 is 90 m. It also shows that the total length of the stock of raw fabric BBB is 190 m.

Further, in the second record, it is stored that the inventory status is "outgoing". This indicates that the raw fabric BBB has been delivered and used for the production of the processed product.

It is remembered that the location of the original tan is "Original yard III" in the third record where the original tan name is "Original tan CCC". This indicates that the original fabric CCC is located at the original fabric storage site III.

In the third record, the number of "raw fabric CCC" in stock is "2", the length of the stock fabric 1 is "100m", the length of the stock fabric 2 is "100m", and the total length is " It is remembered that it is "200m". This is because the number of raw fabric CCCs in stock at the original fabric storage site III is two, the length of the original fabric 1 in the stock of the original fabric CCC is 100 m, and the length of the original fabric 2 is 100 m. It also shows that the total length of the stock of raw fabric CCC is 200m.

Further, in the third record, it is stored that the inventory status is "in storage". This is a state in which the raw fabric CCC has not been ordered and the raw fabric CCC is not used for the production of the processed product. That is, it shows that the original fabric CCC is stored in the original fabric storage site III.

In the inventory management information update process, for example, the inventory status update process is performed. In the inventory status update process, the inventory status of the original fabric corresponding to the card ID of the RFID card 22 on which the card operation was performed is updated. The inventory status is updated to one of the three statuses of "waiting for arrival", "delivering", and "storage" shown in FIG. 5 according to the card operation. The type of inventory status is not limited to this example.

Further, in the inventory management information update process, the inventory amount update process is also performed. The stock quantity is information indicating the stock quantity of raw materials, and includes the stock quantity and the length of the raw material. The data processing unit 426 calculates the amount of raw materials used, for example, based on information on the amount of raw materials used (hereinafter, also referred to as "usage information"). The data processing unit 426 updates the inventory amount based on the calculated usage amount.

The usage information is acquired by, for example, the sensor device 60. Specifically, the sensor device 60 acquires the number of times the cutting machine cuts the original fabric as usage information. The length of the original fabric to be cut at one time is set to, for example, a length corresponding to the sheet part which is a work piece. In this case, the data processing unit 426 calculates the amount of the original fabric used by multiplying the number of cuts measured by the sensor device 60 and the length of the original fabric cut by one cut. Then, the data processing unit 426 subtracts the calculated usage amount of the raw fabric from the length of the raw fabric of the inventory management information. At this time, the data processing unit 426 subtracts the calculated amount of the original fabric used from each of the length of the original fabric used and the total length of the original fabrics 1 to n. As a result of the subtraction, if there is an original fabric having a length of 0 m among the original fabrics 1 to n, the data processing unit 426 subtracts the number of original fabrics having become 0 m from the stock quantity. ..

The usage amount information is not limited to the number of times the cutting machine cuts the original fabric. The usage amount information may be, for example, an captured image acquired by the sensor device 60. The sensor device 60, for example, takes an image of a sheet member cut from the original fabric. The data processing unit 426 calculates the length of the cut sheet member based on the image recognition for the captured image. Then, the data processing unit 426 uses the calculated length of the sheet member as the amount of raw material used to calculate the amount of raw material in stock. Further, the usage amount information may be, for example, the weight before and after use of the original fabric measured by the weight sensor. The data processing unit 426 calculates the difference in weight before and after the use of the original fabric as the amount of the original fabric used.

The usage amount information is not limited to the information acquired by the sensor device 60. The usage amount information may be, for example, preset specification information of the workpiece. As an example, it is assumed that the specification information indicates that two sheet members 10 m from the original fabric AAA are cut. In this case, the data processing unit 426 calculates the usage amount to be 20 m by multiplying the length (10 m) of the sheet member to be cut and the number of sheets (2 sheets) using the specification information as the usage amount information.

In addition, in the inventory management information update process, the arrival length update process is also performed. The data processing unit 426 updates the inventory amount based on, for example, the arrival length input by the worker. Specifically, the data processing unit 426 causes the output unit 340 of the stand-type RFID reader 30 to display the arrival length update screen. Then, the data processing unit 426 adds the arrival length input by the worker on the arrival length update screen to the length and total length of the received original fabrics among the lengths of the original fabrics of the inventory management information. Further, the data processing unit 426 adds the number of received raw fabrics to the number of stocks.

The data processing unit 426 also generates production target information regarding raw materials used for producing the processed product. The production target information includes, for example, the name of the processed product, the name of the raw material, and the location of the raw material. As an example, it is assumed that the work piece is a sheet part DDD and the raw material is a raw material AAA. In this case, the production target information includes the sheet part DDD as the name of the processed product, the raw material AAA as the name of the raw material, and the raw material storage place GGG as the location of the raw material.

The data processing unit 426 may include information for designating raw materials used for production of the processed product in the production target information based on the inventory management information. For example, it is assumed that the stock of the raw fabric AAA includes an unused raw fabric AAA and a raw fabric AAA that is in use and has a length of 10 m. When the length of the sheet member required for cutting the sheet part DDD is 15 m, for example, the remaining 10 m sheet member of the used raw material AAA and the 5 m sheet member cut from the unused raw material AAA. A total of 15 m of seat members is used.

However, for example, when there are a plurality of sheet parts DDD, by dividing the original fabric AAA to be used into two sheet members of 10 m and 5 m, a work loss for exchanging the sheet members occurs.

Therefore, when the number of stocks is a plurality, the data processing unit 426 specifies the raw fabric to be used for the production of the processed product based on the length of each of the plurality of raw fabrics. For example, suppose that there are two stocks of raw fabric AAA. On the other hand, the original fabric AAA is unused and has a length of 100 m. The other raw fabric AAA is in use and has a raw fabric length of 10 m. When the length of the sheet member required for cutting the sheet component DDD is 15 m, the data processing unit 426 determines that the original fabric AAA in use is insufficient in length. Then, the data processing unit 426 specifies that the unused original fabric AAA is used first. As a result, the operating time can be improved in the production of the processed product. In addition, since the worker only needs to carry the unused raw materials among the used and unused raw materials, the work efficiency can be improved.

Further, the data processing unit 426 may determine the layout of the parts in the raw fabric, which indicates the position where the parts to be produced are cut from the raw fabric. For example, the data processing unit 426 may determine the layout (arrangement position and orientation) of each sheet component on the surface of the member sheet, which indicates the position where a plurality of sheet components are cut out from one sheet member.

Specifically, when a plurality of sheet parts are cut from a sheet member cut from the original fabric, the data processing unit 426 determines the layout of the plurality of sheet parts based on the inventory amount. As an example, it is assumed that the length of the sheet member required for cutting a plurality of sheet parts DDD is 15 m, but the stock amount of the original fabric AAA is 14 m. In this case, the data processing unit 426 determines the layout of each sheet component DDD so that all the sheet component DDDs are contained in the 14 m sheet member. As a result, the raw materials can be effectively used in the production of the production target.

When the processing target is a processed product and the terminal ID corresponds to the production process related to the production plan of the processed product, the data processing unit 426 executes the process related to the production plan of the processed product indicated by the card ID received together with the terminal ID. .. For example, the data processing unit 426 executes a production plan generation process that generates production plan information indicating a production plan of the work piece corresponding to the RFID card 22 to which the slide-in has been performed. In the present embodiment, the production plan information is stored in the production plan information database of the storage unit 430.

Here, the production planning information will be described with reference to FIG. FIG. 6 is a diagram showing an example of the configuration of the production plan information table in the production plan information database according to the present embodiment. In the following, an example in which the processed product is an automobile seat part will be described. As shown in FIG. 6, the records in the production plan information table include production order, production target (processed product), raw material, scheduled production date, scheduled production start time, scheduled production end time, actual production date, and actual production start time. , Production end time, and production status are included. The information included in the record of the production planning information table is not limited to this example.

The production order indicates the order in which the production target is produced. The production target (processed product) indicates the name of the production target. The raw material indicates the name of the raw material. The planned production date indicates the planned production date of the production target. The scheduled production start time indicates the scheduled start time of the production target on the scheduled production date. The scheduled end time of production indicates the scheduled end time of production of the production target on the scheduled production date. Indicates the actual production date and the date when the production of the production target is completed. The actual production start time indicates the time when the production of the production target is started on the actual production date. The actual production end time indicates the time when the production of the production target ends on the actual production date. The production status indicates the production status of the production target.

For example, in the first record in which the production order is "001", it is stored that the production target is "sheet part DDD" and the raw material is "raw material AAA". This indicates that the sheet component DDD is first produced using the raw fabric AAA.

Further, in the first record, it is stored that the scheduled production date is "October 5", the scheduled production start time is "10:10", and the scheduled production end time is "10:20". .. This indicates that production of the sheet component DDD will start at 10:10 on October 5th and will end at 10:20.

Further, in the first record, it is stored that the actual production date is "October 5", the actual production start time is "10:10", and the actual production end time is "10:19". .. This shows the record that the production of the sheet part DDD started at 10:10 on October 5th and ended at 10:19.

Further, in the first record, it is stored that the production state is "production completed". This indicates that the production of the "seat component DDD" has been completed.

In the second record in which the production order is "002", it is stored that the production target is "sheet parts EEE" and the raw material is "raw material BBB". This indicates that the sheet part EEE is produced second using the raw fabric BBB.

In the second record, it is remembered that the scheduled production date is "October 5", the scheduled production start time is "10:20", and the scheduled production end time is "10:30". .. This indicates that production of the seat component EEE will start at 10:20 on October 5th and will end at 10:30.

In the second record, it is memorized that the actual production date is "October 5", the actual production start time is "10:20", and the production status is "in production", and the actual production end time is set. It is blank. This indicates that the production of the sheet part EEE started at 10:20 on October 5, and is still in production.

In the third record in which the production order is "003", it is stored that the production target is "sheet part FFF" and the raw material is "raw material CCC". This indicates that the sheet component FFF is produced third using the raw fabric CCC.

In addition, the third record stores that the scheduled production date is "October 5", the scheduled production start time is "10:30", and the scheduled production end time is "10:40". .. This indicates that production of the sheet component FFF will start at 10:30 on October 5th and will end at 10:40.

Further, the actual production date, the actual production start time, the actual production end time, and the production status of the third record are blank. This indicates that the production of the sheet component FFF has not yet started and is in an unproduced state.

The data processing unit 426 generates each record of the production plan information table shown in FIG. 6 as production plan information in the production plan generation process.

The data processing unit 426 may further generate production schedule list information, which is information included in the production schedule list, based on the generated production plan information in the production plan generation process. For example, the data processing unit 426 generates information including the production order, the production target (processed product), the raw material, the scheduled production date, the scheduled production start time, and the scheduled production end time as the production schedule list information in the production plan information. To do. The information included in the production schedule list information is not limited to this example.

The data processing unit 426 may display the production plan information generated in the production plan generation process on the display device 50.

When generating the production plan information, the data processing unit 426 may determine the production order of the plurality of processed products so as to satisfy a predetermined condition based on the raw materials used for the production of each of the plurality of processed products. The predetermined condition is, for example, "to make the production order of the processed products produced using the same raw material continuous". The predetermined conditions are not limited to such an example. Further, a plurality of conditions may be set as predetermined conditions. Further, the data processing unit 426 may change the determined production order to the production order specified by the worker. As a result, the worker can produce the workpieces in an irregular order.

Further, when the processing target is a processed product and the terminal ID corresponds to the production process related to the production of the processed product, the data processing unit 426 determines the production record of the processed product corresponding to the RFID card 22 on which the card operation has been performed. Execute the production record update process to be updated. For example, the data processing unit 426 updates the production actual date, the production start actual time, the production end actual time, and the production state of the information included in the production plan information. The production state is updated to one of the two states of "production completed" and "in production" shown in FIG. 6 according to the card operation. The type of production state is not limited to such an example. After updating the production record, the data processing unit 426 updates the display of the production record of the production plan information displayed on the display device 50.

The data processing unit 426 executes processing on the RFID card 22 based on whether or not the card operation has been performed by the operator. For example, it is assumed that the determination result by the determination unit 424 indicates that the card operation has been performed on the RFID card 22. In this case, the data processing unit 426 executes the process. On the other hand, it is assumed that the determination result by the determination unit 424 indicates that the card operation has not been performed on the RFID card 22. In this case, the data processing unit 426 does not execute the processing.

When executing the process, the data processing unit 426 determines the process to be executed based on the card ID of the RFID card 22 on which the card operation was performed and the terminal ID of the stand-type RFID reader 30 on which the card operation was performed. In the present embodiment, the information indicating the processing executed by the data processing unit 426 is stored in the reading device information database of the storage unit 430 in association with the terminal ID, the card ID, and the card operation. Therefore, the data processing unit 426 refers to the reader information database using the terminal ID, the card ID, and the card operation as search keys, and determines the processing to be executed.

The output processing unit 428 performs processing related to the output of various information. For example, the output processing unit 428 causes the display device 50 to display information on the work piece corresponding to the RFID card 22 on which the card operation has been performed.

For example, the output processing unit 428 performs the production plan display processing. The production plan display process is a process of displaying the production schedule list on the display device 33 and displaying the production plan information on the display device 50. As an example, it is assumed that the processed RFID card 22 is slid into the card slot of the stand-type RFID reader 30 provided in the device card storage area.

As an example, it is assumed that the processed RFID card 22 is slid into the card slot of the stand-type RFID reader 30 provided in the device card storage area. At this time, the output processing unit 428 causes the display device 33 of the stand-type RFID reader 30 into which the RFID card 22 is slid in to display the production target information. As a result, the location of the raw material included in the production target information is displayed on the display device 33, and the labor of the operator searching for the raw material is saved. Therefore, the work efficiency of the worker is improved.

Further, the output processing unit 428 performs the specification display processing. The specification display process is a process of displaying the specifications of the work piece on the display device 33. As an example, it is assumed that the RFID card 22 of the processed product is slid into the card slot of the stand-type RFID reader 30 provided near the cutting machine. At this time, the output processing unit 428 causes the display device 33 of the stand-type RFID reader 30 into which the RFID card 22 is slid in to display the specifications of the work piece. This saves the worker the trouble of searching for the specifications to be produced. Therefore, the work efficiency of the worker is improved.

Further, the output processing unit 428 may output a warning. For example, the output processing unit 428 outputs a warning when the operator performs an erroneous operation on the RFID card 22. The warning may be output as an image to the display device 33, or may be output as a voice by the voice output device.

In addition, the determination unit 424 performs a picking check when the RFID card 22 corresponding to the raw material set in the production apparatus for producing the processed product such as the rolling table and the cutting machine is slid in. May be good. The picking check is to check whether the raw materials set in the production equipment by the operator are correct. The determination unit 424 determines, for example, whether or not the raw material set in the production apparatus is correct based on the production planning information.

Specifically, the determination unit 424 collates the work piece corresponding to the card ID of the slide-in RFID card 22 with the work piece to be produced next, which is indicated by the production planning information. As a result of the collation, when it is determined that an erroneous operation has been performed on the RFID card 22, the determination unit 424 causes the output unit 340 of the stand-type RFID reader 30 to output a warning via the output processing unit 428. This reduces mistakes by workers in setting raw materials in production equipment. Therefore, production loss due to incorrect setting of raw materials can be reduced.

The determination unit 424 may determine whether or not the operation performed on the RFID card 22 is correct based on the production planning information. For example, suppose that an operator performs a card operation on an RFID card 22 of a processed product in order to start production of the processed product. At this time, the determination unit 424 collates the work piece corresponding to the RFID card 22 with the work piece to be produced next, which is indicated by the production planning information. As a result of the collation, when it is determined that an erroneous operation has been performed on the RFID card 22, the determination unit 424 causes the output unit 340 of the stand-type RFID reader 30 to output a warning via the output processing unit 428.

The storage unit 430 has a function of storing various types of information. For example, the storage unit 430 stores various databases. Specifically, the storage unit 430 stores a card information database, an inventory management information database, a production plan information database, and a reader information database. The database stored by the storage unit 430 is not limited to this example.

The storage unit 430 is a storage medium such as an HDD (Hard Disk Drive), a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), a RAM (Random Access read / write Memory), a ROM (Read Only Memory), or a storage medium thereof. It is composed of any combination of storage media. For the storage unit 430, for example, a non-volatile memory can be used.

The display device 50 is realized by, for example, a monitor. The display device 50 is provided in each process. The display device 50 displays, for example, the production plan information input from the production process management server 40. As a result, the worker can visually recognize the production planning information.

The sensor device 60 is a device that acquires usage information. The sensor device 60 transmits the acquired usage information to the production process management server 40. The sensor device 60 can be realized by various devices.

For example, the sensor device 60 is realized by a photoelectric sensor. The photoelectric sensor measures the number of times the original fabric is cut by the cutting machine as usage information. The photoelectric sensor is composed of, for example, a floodlight that outputs light and a receiver that receives the light output by the floodlight. When the light output from the floodlight is blocked by an object or the like and the light receiver cannot detect the light, the photoelectric sensor detects that the object has passed between the floodlight and the light receiver. The photoelectric sensor is provided, for example, so that the blade of the cutting machine passes between the floodlight and the light receiving device when the cutting machine cuts the original fabric. As a result, the photoelectric sensor can count the number of times the blade of the cutting machine has passed between the floodlight and the light receiver, and can count the number of times the cutting machine has cut the original fabric.

Further, the sensor device 60 may be realized by an image pickup device. The image pickup apparatus, for example, takes an image of a sheet member cut from the original fabric by a cutting machine and acquires an captured image. The image pickup device is provided, for example, at a position where the entire cut sheet member can be imaged. Further, the sensor device 60 may be realized by a weight sensor. The weight sensor measures, for example, the weight of the original fabric before and after cutting.

When the raw material is a liquid, the image pickup apparatus may image the position of the liquid surface of the liquid. The data processing unit 426 may calculate the amount of the raw material used based on the image recognition of the captured image before and after the use of the raw material.

Further, the object wound as the original fabric is not limited to the sheet-shaped object as long as it is a long-shaped object. For example, it may be a thread-like or string-like object. In addition, inventory management of raw fabrics wound with thread-like or string-like objects is performed based on changes in length and weight before and after use, similar to inventory management of raw fabrics wound with sheet-like objects. ..
