In addition, a large amount of cost was required for the introduction. Furthermore, it is suitable for manufacturing a large lot / constant process flow, but it is difficult to operate in a factory where process changes frequently occur in a small lot.

  Further, the second physical distribution method has a problem that it depends on the input of arrival completion information by a factory worker, and an input work burden and an input error occur. In addition, the completion information for the production management / process management system is input about the start / completion of the work in the process, and the information system system must grasp the actual position and flow of the object. There was a problem that I could not.

  In the third distribution method, due to the busy situation of the workers, the distribution work is delayed, the necessary parts are not properly flowed to the next process, or the parts are temporarily stored in the storage area, or the parts themselves are lost in the factory. There was a problem. In addition, all the responses such as sudden interruptions and process changes due to the load status of some equipment are left to human judgment, and there is a problem that the information system cannot be grasped.

  Furthermore, even if unprocessed parts and work-in-process parts remain in the process, the procedure is left to human judgment, causing a delay in delivery.

  In the fourth physical distribution system, a conventional transport device with an information terminal is designed to sequentially transport a predetermined process to one work order, and responds to transport requests that occur asynchronously in each process. I never did.

  As described above, in the related art, unless a manufacturing based on a complete manufacturing schedule and an automatic transfer system linked to the schedule are introduced, parts are not transferred to the next process after the process operation is completed and stay in the process. It is not transported to the next process and stays in the work in process storage area. In the next process, there is a problem that the part to be worked does not reach and work waiting occurs.

  That is, in a factory where a strict manufacturing schedule cannot be set, there is a problem that it is difficult to manage the location of parts and prevent the retention of parts, waiting for parts, and loss in the work in process storage area. Furthermore, it is difficult for the information system system to grasp the flow of things in the factory and to change schedules and processes as needed.

This is a logistics support system.

  The invention according to claim 2 is the physical distribution support system according to claim 1, wherein the component is identified by an ID medium.

  The invention according to claim 3 is the physical distribution support system according to claim 1 or 2, further comprising a work-in-place storage for temporarily storing the parts based on the judgment of the physical distribution management server unit.

  In the invention according to claim 4, the logistics management server unit searches for a part whose carry-in time for the next process is equal to or less than a predetermined value, and instructs the transport terminal to carry out the work-in-process storage area. A logistics support system according to claim 3.

  According to a fifth aspect of the present invention, in the physical distribution support method for supporting transportation between parts manufactured by a plurality of processes, a process terminal is disposed at each predetermined location corresponding to the plurality of processes, and the transport terminal is provided. Receiving the loading / unloading information of the parts acquired by the above, and performing logistics management processing for grasping in real time the location of the parts and the manufacturing process progress status of the parts, and the transfer terminal requests the process terminal processing or logistics management processing It is a physical distribution support method for moving between the processes freely according to the situation and instructing loading / unloading of parts.

  As described above, according to the present invention, for a factory where it is difficult to install an automatic transfer system in terms of installation and operation, the transfer device upon completion of the process and the request for transfer to the next process are notified to the transfer device in real time. Necessary when necessary items are managed by controlling the location of the parts by transporting, preventing stagnation of parts in the process and work-in-process storage, and preventing waiting for parts to arrive in the next process. There is an effect that it is arranged to a different place.

  In addition, the system can constantly monitor the distribution of the factory where schedule delays and stagnation have occurred and the information on the parts group being conveyed and notify the human system to improve production. effective.

  In addition, an instruction for conveyance can be issued simultaneously with completion of the process operation, and there is an effect that it is possible to prevent stagnation of parts already worked in the process.

  On the other hand, by designating the next process and the like, there is an effect that it is possible to prevent the loaded parts from being left in the work-in-process storage area or staying. In addition, since the parts are carried in at the designated time, it is possible to prevent waiting for the arrival of the parts.

  In addition, the system can constantly monitor the physical distribution status at the site, and it is possible to easily prevent stagnation and delay delivery due to process changes and schedule changes in human systems, production management, and process management systems. There is.

  Please refer to FIG. An example is shown in which parts are loaded on the transfer terminal 3A in response to a call from the process terminal (or also called a stop) 2A and transferred to the next process according to the process order.

  In step S401, a call is made from the process terminal (or process terminal unit 2) 2A to the transfer terminal (or transfer terminal unit 3) 3A. In step S402, the process moves to the calling process terminal 2A.

  In step S403, the parts are loaded at the calling process terminal 2A. In step S404, the process moves to the instructed process. In step 405, the process moves to the instructed process terminal 2A and unloads the part.

  Please refer to FIG. Regarding transportation, refer to the production management schedule and adjust the delivery time. In the case where there is a time from unloading to unloading in the previous process, it is placed in a work-in-place storage area such as a parts storage area or a warehouse, and an example is shown in which the system gives an instruction to carry-in during the loading time.

  In step S501, there is a call from the process terminal 2A to the transfer terminal 3A. In step S502, the transfer terminal 3A moves to the calling process terminal 2A. In step S503, the parts are loaded at the calling process terminal 2A.

  In step S504, the parts are once carried into the work in process storage area. In step S505, the parts are loaded in the work-in-process storage area in accordance with the delivery time of the own process. In step S506, unloading is performed in a target process. Thereby, even when the time from carrying out a part to carrying in a part is large, the transport terminal 3A can be used efficiently without being occupied.

  The operation of the above-described physical distribution support system BSS will be described in more detail with reference to FIGS.

  Please refer to FIG. 6 and FIG. Issue work instructions for production instructions to the factory. The component IDNo is written to the IC tag at the same time, and indicates the operation of notifying the content management server 1A of the contents.

  That is, in step S601, a production order is selected. In step S602, the manufacturing order and process information are acquired from the production management database.

  In step S603, writing to the production order ID No table is performed. In step S604, writing to the order-specific process plan table is performed. In step S605, the component ID No is written to the ID medium (IC tag). As a result, information related to the manufacturing order is stored in the physical distribution management server unit 1.

  Here, as shown in FIG. 26A, the production order ID No table is a table that stores a part ID No 2601a, a production order No 2602a, a product No 2603a, a part No 2604a, and a production quantity 2605a in association with each other. In addition, the order-specific process plan table is a table for associating and storing component ID No 2601b, process (1) 2602b, process (2) 2603b, and the like, as shown in FIG. In addition, each said process contains the information of process IDNo, carrying-in time, and carrying-out time. Further, the number of processes of the component ID No is not limited to two processes, and all information on the required number of processes is continuously recorded in the order of processes.

  Please refer to FIG. 7, FIG. 8, FIG. 9, FIG. When the work of the own process is completed, the completed work instruction is read into the IC tag reader of the process terminal (all in a plurality of cases), the completion call button is pressed, and the transport terminal (in this example, the carriage is used as an example of the transport terminal). This shows the operation to notify (assumed). In addition, an operation in a case where it is notified that there has been a request for conveyance from a certain process is shown.

  That is, in step S701, a call screen is displayed by pressing the call button on the process terminal 2A (see FIG. 20). In step S702, the component ID No is read from the ID medium (multiple IDs are allowed). In step S703, the component ID No and the ID of the process terminal 2 are transmitted to the physical distribution management server unit 1.

  In step S704, the distribution management server unit 1 searches the production order ID No table by the component ID No, and acquires the production order No and the component No. In step S705, the transport cart table is searched.

  Here, as shown in FIG. 27B, the transport cart table is a table that stores a cart No. 2701b, a part ID No. 2702b, a production order No. 2703b, a part No. 2704b, a load quantity 2705b, a next process 2706b, and an arrival order 2707b in association with each other. .

  In step S706, it is determined whether the carriage is unused (no manufacturing order number?). When in use, the process returns to step S705. When it is not used, the process proceeds to step S710. If all are in use, the process proceeds to step S707. In step S707, a search is made for a cart that first arrives at the process terminal.

  Here, the “car that arrives first” is a car that is in the place closest to the place of its own process terminal. For example, if a plurality of trucks can arrive at the process terminal, the logistics management server unit 1 can identify the truck in the nearest place because it knows which process (or between the processes) the truck is in. . Further, the reason for limiting to the case where all the trolleys are in use is to preferentially use the trolley when there is an empty trolley. Thereby, efficient cart selection can be performed.

  In step S708, it is determined whether a carriage has been determined. When the carriage is determined, the process proceeds to step S710. When the cart is not yet determined, the process proceeds to step S709.

  In step S709, the first cart that arrives at the process closest to the process terminal is searched. In step S710, the order-specific process plan table is searched by the part ID No, the process ID No of the next process (n) of the process terminal ID of the own process is acquired, and the destination is determined. In step S711, the part number, the next process, and the carriage number are transmitted. In step S712, the process terminal 2A displays the part number, the next process, and the cart number.

  In step S713, the logistics management server unit 1 transmits the ID No. of the part to be loaded on the cart of the decided cart No., the component No., and the called process terminal ID.

  In step S714, the transport terminal 3A displays a cart call screen as shown in FIG. 21, and displays the process terminal ID of the call destination. In step S715, the patrol light is turned on. In step S716, the confirmation button is pressed to turn off the patrol light.

  Please refer to FIG. 10, FIG. 11, and FIG. When the transport terminal 3A arrives at the called process, it loads the completed parts. Then, the work instruction sheet for the component to be loaded is read by the IC tag reader of the carriage. Each operation of loading the target parts on the cart is shown.

  In step S1001, the loading screen is displayed by pressing the loading button on the transfer terminal 3A (see FIG. 22). In step 1002, a list of component numbers transmitted from the logistics support server is displayed. In step S1003, the ID reading device reads the component ID No.

  In step S1004, a comparison is made with the IDs on the list. If not, the process returns to step S1003. If they match, the process proceeds to step S1005. In step S1005, the loaded quantity is input.

  In step S1006, it is determined whether all the parts on the list have been read. If not completed, the process returns to step S1003. When the reading is completed, the process proceeds to step S1007. In step S1007, a confirmation button is pressed to notify the distribution support server of completion of loading.

  In step S1008, the physical management server unit 1 writes the current time in the unloading time of the target process in the record of the target part ID No. in the process result table.

  In step S1009, the loading quantity is subtracted from the staying quantity of the record in which the target process ID No in the process-specific part table matches the target part No. Then, the current time is written in the carry-out time.

  Here, the process-specific parts table is a table that associates and stores process ID No. 2701a, part ID No. 2702a, part No. 2703a, staying quantity 2704a, carry-in time 2705a, and carry-out time 2706a, as shown in FIG.

  In step S1010, the production order table is referred to from the loaded part ID No in the record of the target carriage No. in the conveyance carriage table, and the part information is registered. This is a process of registering which parts are currently loaded on the cart.

  Then, from the part ID No., the order-specific process plan table is referred to and set in the next process of the transport carriage table. This is a process of specifying which process the part is to be transported next.

  When there is no record in the corresponding cart No., 1 is set in the order of arrival. When no parts are loaded on the cart, the arrival order is set to the first. Thereby, the carriage can be effectively used in real time.

  If there is a record, if there is the same next process ID No, the order of arrival is the same. When other parts are already loaded, if there is an identical process, the parts are conveyed at the same time. If there is no identical process, the parts are conveyed last.

  In step S1011, it is determined whether processing for the number of parts on the list has been completed. If not completed, the process returns to step S1008. When complete, the process ends.

  Please refer to FIG. 12 and FIG. The cart displays the next process to go to. And the operation | movement which displays an optimal process in consideration of a loading order, a process delivery date, and a path | route is shown.

  In step S1201, the next process button is pressed on the transfer terminal 3A to display the next process screen (see FIG. 23). In step S1202, the carriage No is transmitted to the logistics support server, and next process information is requested.

  In step S1203, the distribution management server 1 searches the transport cart table by the cart No., and searches for the record having the smallest arrival order value. In step S1204, the next process, component ID No, and component No of the retrieved record are transmitted.

  In step S1205, the received next process is displayed on the transfer terminal 3A (for example, a welding area, see FIG. 23). In step S1206, the received component ID No and component No are stored.

  This will be described in more detail with reference to FIGS. 13, 14, 15, 16, and 24. FIG. The operation when the location is changed to a work in process storage such as a warehouse is shown.

  Further, when the system automatically instructs the system to automatically carry out the part from the work-in-process storage area for a part whose carry-in time in the next process is equal to or less than a predetermined value (for example, basically, the work-in-process storage area for the transfer terminal 3A). Notification of a call from).

  Please refer to FIG. 13 and FIG. In step S1301, the next process button is pressed on the transfer terminal 3A to display the next process screen. In step S1302, a bogie No is transmitted to the physical distribution management server 1 to request next process information.

  In step S1303, the order-specific process plan table is referred to by the component ID No. loaded in the physical distribution management server unit 1. In step S1304, the conveyance time of the process ID next to the current process ID is referred to.

  In step S1305, it is determined whether or not the time obtained by subtracting the current time from the carry-in time is longer than a predetermined waiting time. When it is determined that the time is within the waiting time, the process proceeds to step S1310. When it is determined that the waiting time is exceeded, the process proceeds to step S1306.

  In step S1306, the ID of “temporary work-in-place storage” is inserted between the current process and the next process in the process result table. In step S1307, the next process ID is transmitted as “temporary work-in-place storage”. In step S1308, the received next process ID is displayed on the transfer terminal 3A. In step S1309, the received component ID No and component No are stored. Then, the process ends.

  On the other hand, in step S1310, the distribution management server unit 1 performs normal transport destination designation processing (S1203, S1204).

  With reference to FIG. 14, FIG. 15 and FIG. 16, the process of transporting the parts transported to the “temporary work place storage” to the original process will be described. This process is executed continuously at predetermined intervals in the physical distribution management server unit 1.

  In step S1401, the physical distribution management server 1 refers to the process performance table and searches for a record whose process ID is “temporary work-in-place storage”. In step S1402, the order-specific process plan table is referred to by the part ID No of the retrieved record.

  As shown in FIG. 26C, the process result table is a table that stores the component ID No 2601c, the process (1) 2602c, and the process (2) 2603c in association with each other. Further, the number of part ID No. processes is not limited to two processes, and all information on the number of required processes is continuously recorded in the order of processes. Each process includes information of process ID No, carry-in time, and carry-out time.

  In step S1403, it is determined whether the time obtained by subtracting the current time from the carry-in time of the same process ID as the next process ID is shorter than the specified time. If it is longer than the specified time, the process proceeds to step S1405. When it is less than the specified time, the process proceeds to step S1404. In step S1404, the conveyance part ID No is extracted.

  In step S1405, it is determined whether or not the record extraction process of “temporary work-in-place storage” in the process performance table has been completed. If not completed, the process returns to step S1401. If completed, the process proceeds to step S1406. In step S1406, the production order ID table is searched by the component ID No, and the order No and the component No are acquired. In step S1407, the transport cart table is searched.

  In step S1408, it is determined whether the carriage is unused (no manufacturing order number?). When it is not used, the process proceeds to step S1412. When in use, the process returns to step S1407. Then, when all are in use, the process proceeds to step S1410.

  In step S1409, the first cart that arrives at the temporary work-in-process storage is selected. In step S1410, it is determined whether a carriage has been determined. When the carriage is determined, the process proceeds to step S1412. When the cart is not yet determined, the process proceeds to step S1411.

  In step S1411, a search is made for a cart that arrives first in the process closest to the temporary work-in-place storage. In step S1412, the order-specific process plan table is searched with the part ID No, the process next to the process terminal ID is acquired, and the destination is determined.

  In step S1413, the component ID No, the component No, and the calling process ID of the component to be loaded on the cart of the determined cart No are transmitted.

  In step S1414, the carriage terminal 3A displays a cart call screen and displays the process name of the call destination. In step S1415, the patrol light is turned on. In step S1416, when the confirmation button is pressed, the patrol light is turned off and the process ends (see FIG. 24).

  Please refer to FIG. 17, FIG. 18 and FIG. The operation of moving the truck to the target process and unloading parts is shown.

  In step S1701, the unloading button is pressed on the transfer terminal 3A to display the next process screen (see FIG. 25). In step S1702, a list of stored part numbers is displayed (for example, A001-1234, A002-1150, A003-5800). In step S1703, the component ID No is read by the ID reading device.

  In step S1704, a comparison is made with the IDs on the list. If not, the process returns to step S1703. If they match, the process proceeds to step S1705. In step S1705, the unloaded quantity is input.

  In step S1706, it is determined whether the number of parts on the list has been read. If the reading has not been completed, the process returns to step S1703. When the reading is completed, the process proceeds to step S1707. In step S1707, a confirmation button is pressed to notify the distribution management server 1A of completion of unloading.

  In step S1708, the distribution management server unit 1 writes the current time in the import time of the target process of the record of the target part ID No. in the process result table. In step S1709, the unloading quantity is added to the staying quantity of the target part ID No. record of the target process ID No. record of the target part ID table, and the current time is written in the carry-in time. In step S1710, the part ID No. record unloaded in the target carriage No. record in the transport carriage table is deleted.

  In step S1711, it is determined whether or not processing for the number of parts on the list has been performed. If not completed, the process returns to step S1708. When it is completed, the process proceeds to step S1712. In step S1712, 1 is subtracted from the arrival order of all the records of the corresponding carriage No in the transport carriage table, and the process is terminated.
