Description

  The present invention relates to a sheet metal processing system, a processing schedule management method, a component conveyance management method, a control method, a control device, and a program for nesting component information on a material sheet and processing with a blank processing machine (drilling / cutting).

  In a conventional sheet metal processing system, a material sheet for processing with a punching / cutting machine (punching, laser, or compound machine) based on a production plan of how many parts to manufacture by what time in advance. A sheet processing program in which component information (graphic data, CAM data, etc.) is nested and a processing schedule are created by a nesting system. And the sheet processing was performed by preparing the material sheet | seat required for execution of the sheet | seat processing program and a processing schedule, and the metal mold | die for a process in advance, and carrying out a schedule driving | operation of the drilling / cutting machine.

  Further, the material sheet after drilling / cutting was manually separated and sorted from the processed sheet material at an outside location other than the processing machine equipment. After that, it was manually transported to the next step bending equipment. In addition, based on the processing schedule of the parts that have been conveyed, the bending machine calls the corresponding processing program, registers the processing program in the processing machine, and performs bending after the mold is set up for bending.

  In addition, the punching / cutting machine has a mechanism for performing automatic accumulation and nesting image accumulation for each component by a component pickup device on an iron pallet (skid) in a shelf (see FIG. 37). FIG. 39 shows the flow of nesting image integration operation. Create a material sheet processing program for parts in the production plan. Thereafter, the sheet is processed with a punching / cutting machine, and the nesting image is integrated with a component pickup device. In this case, there are two integration methods.

  The first is an example in which each sheet (Sh1, Sh2, Sh3) is stacked and stacked on the same component stacking pallet. The second is an example in which each sheet is stacked on a different component stacking pallet, and FIGS. 40 and 41 show the flow of processing for stacking by component. In advance, the grouping of whether or not the relevant parts of the production plan can be accumulated and arranged on the component accumulation pallet (skid) and the accumulation arrangement processing on the component accumulation pallet are performed. After that, a material sheet processing program is created for each part group that can be collected and distributed on the part collection pallet. After that, the sheet is processed by a punching / cutting machine, and the parts are automatically collected on a parts collection pallet previously assigned by a parts pickup device. (See Patent Documents 1 and 2)

  As another method, for a corresponding part of the production plan, the production plan is grouped under grouping conditions such as material / drilling cutting machine / next process machine / delivery date, and then a material sheet machining program is created. Based on the result of the material sheet processing program, the stacking process on the component stacking pallet (skid) is automatically or manually performed. If the same part in the corresponding material sheet processing program cannot be accumulated and arranged on the same component accumulation pallet (skid), there is a method of performing accumulation and arrangement processing on another component accumulation pallet (skid).

The above-described component-by-part integration method slightly reduces the problem of Patent Document 1. Since strict component grouping processing has not been performed before the material sheet is created, the material yield can be improved and the number of material sheet replacements can be reduced.
Japanese Patent No. 3211789 US Pat. No. 5,844,806

The conventional technique has a certain effect when a medium lot having a certain number of production lots is processed or when the processing schedule order of the next process (welding, bending process, secondary process) is not considered. However, it is based on the processing schedule sequence of the next process (welding, bending, secondary process) in the case of realizing remarkable multi-product small lot production (including single-flow machining), frequent interruption production and ultra-short delivery time in recent years. When considering the processing schedule order of the drilling / cutting process, in the case of production form units, product family units, etc., conventional drilling / cutting equipment materials / part pallets (skids) In a system with a limited pallet quantity or limited pallet (skid) storage area (FIG. 37), a component integration method or nesting integration by creating a sheet processing program for component integration (see Patent Documents 1 and 2). There were the following problems in implementing the method.

(1) When a processing schedule and sheet processing program created in advance by nesting processing are to be executed later in actual processing, the original data cannot be used because there is no empty parts pallet. The sheet machining program needs to be changed and machining as planned cannot be performed.

(2) The material yield at the time of material sheet allocation is significantly reduced. In consideration of material costs, it will eventually be necessary to put together multiple production plans.

(3) The parts collected on the parts collection pallet are once manually sorted / reloaded. At that time, it takes time and effort to make a match between the actual part and the actual product form output in production management, and an allocation error may occur.

(4) The component accumulation efficiency on the component accumulation pallet decreases, the pallet replacement setup and the integration component take-out setup frequency greatly increase, and the operation rate significantly decreases.

When the number of processing lots is one or several, there is no effect of integration by part, and nesting image integration is unavoidable. Even in this case, considering the reduction in the number of parts pallet replacements, the mixed mounting is performed on the same parts pallet . In this case, in order to transport the assembled parts to the next process, manual sorting / reloading work is required once.

(5) After that, restrictions such as the need for many transport pallets and a large storage location for transporting the sorted parts occur.

(6) Since the transport timing of the sorted parts to the next process and the supply timing of the alternative empty pallet are not managed, each worker is restrained, increasing man-hours and waiting for work at each processing machine. It causes the rate to decrease.

(7) At the same time, it is a major cause of the increase in setup work such as searching for parts in the next process such as a bending machine, parts arrangement before bending, and mold preparation and lowering the operating rate. Become a realistic situation.

(8) There is a problem in the integration of parts on the current iron pallet (skid) and the nesting image, and also in the case of the following parts. There are parts that should not be scratched (stainless steel, colored steel plates, items that directly use the surface), and there are molding parts that cannot be stacked. Therefore, only one nesting image is integrated. In such cases, parts pallets (skids) will be replaced frequently, and the more the material sheet processing program is being processed or the more frequent switching of different material sheet processing programs is, the more the processing rate of the processing machine will be Lowering and increasing replacement setup work result in lower productivity and higher costs.

[3] The overall system flow in the present invention will be described.

(1) About the overall system flow (see Figure 1):
The production management system 100 requests the process progress management apparatus 200 to make a production arrangement (manufacture how many parts by what time) for a processing machine in each bending process of the next process.

Based on the production request, the process progress management device 200 creates a process schedule in the process scheduler process for the processing machine of each bending process of the next process . In the processing scheduler process, a common mold layout and a processing schedule (work instruction) are created by a bending scheduler (multi-item batch mold setup function) so as to minimize the mold exchange setup in a plurality of production arrangements.

  Thereafter, a process leveling process is performed in the bending process.

  Based on the manufacturing arrangement for drilling in consideration of the processing schedule of the bending process, in the process scheduler process of each drilling / cutting process of the previous process of the process progress management apparatus 200, the plate layout arrangement process (nesting) of the automatic programming apparatus 300 is once performed. Create a material sheet processing program. At the same time, a processing schedule, sheet information, a component extraction instruction program, and a component accumulation instruction program (temporary data) are created. The processing schedule and sheet information are returned to the processing scheduler process. On the processing scheduler side, after the process leveling process of each processing cell, the processing schedule is finally determined. As a result, the confirmed machining schedule, machining program, sheet information, component take-out instruction program, and component accumulation instruction program are transferred to the punching / cutting cell overall management device 400.

  Further, when the target drilling / cutting process is limited to only one facility, or when the parts are previously used in the processing facility process, the drilling / cutting cell integrated management device directly from the automatic programming device 300. 400 may be passed.

  Then, the cell operation processing is executed by the schedule operation function on the drilling / cutting cell overall management device 400 side. When processing micro-jointless sheets, parts are picked up by the parts pick-up device 1250, and the optimum stacking arrangement on the parts stacking pallet (skid) and laying wagon / tray is automatically generated during the stacking process. Controls automatic allocation of pallets and serving wagons / tray. At that time, the current material / part inventory information is updated.

(2) Regarding major differences between conventional operation and operation of the present invention:
In the conventional operation, component sorting and accumulation data on each component accumulation pallet is created at the time of creating a sheet processing program by nesting processing of an automatic programming device. During the actual scheduled operation, the parts were manually reloaded, arranged, and transported in the order of the corresponding scheduled operation while the parts collection pallet was manually replaced .

  In the present invention, at the time of the schedule operation by the schedule operation means 410 of each cell overall management device 400, the distribution wagon / tray allocation corresponding to the corresponding sheet processing program and the creation of the component accumulation instruction program are made by the shelf / wagon / tray distribution schedule. The processing means 460 creates each time. At the same time, the distribution wagon schedule processing means of the wagon supervising management device 500 performs accurate location management of the distribution wagon / tray between each empty / actual wagon standby place and the processing machine of each processing process, and schedules in each processing process Synchronize with the operation, create an accurate distribution transport schedule of the corresponding wagon / tray at the required timing, and instruct the worker to replace the wagon / tray and transport setup.

[4] The implementation contents of each system will be described.

(1) About the automatic programming device 300 (planning arrangement processing: nesting):
In the automatic programming device 300, the parts instructed by the production plan information are taken out of the sheet, and based on the part take-out rules, the sheet take-out / part take-out means creates the sheet take-out of each part, the processing program creation, and the part removal instruction program. Based on the conditions for sorting and collecting area information and the conditions for sorting and collecting area information and the current material / parts inventory information and the rules for determining the collecting area, based on the created processing schedule, sheet processing program, and part take-out program. A component accumulation instruction program is created by the component accumulation position instruction process.

(2) About the drilling / cutting cell overall management device 400 (see FIG. 2) and the system flow (see FIGS. 9 to 17):
The punching / cutting cell overall management device 400 is configured by each unit shown in the system block diagram (see FIG. 2). The schedule operation means 410 is the core of the drilling / cutting cell overall management device 400, and is a shelf / die usage status collection process 411, a material / part shelf optimum management process 412, a pre-schedule determination process 413, and a setup navigation process 414. , Schedule operation processing 415, and control processing 416 between various control means.

  The cell control unit 420 performs control processing with various control units based on the schedule operation command and the machining program transfer command from the schedule operation unit 410.

  The shelf management & control unit 430 processes inventory management and conveyance control of the material / part storage shelf device 1200 by the shelf control program command from the schedule operation unit 410 or the shelf control program command of the shelf management & control unit 430 itself.

  The shelf / wagon / tray distribution scheduling processing means 460 schedules part allocation pallets and part distribution (accumulation position) allocation on the distribution wagon / tray for each processing schedule unit from the schedule operation means 410, and performs wagon / tray management. & Control unit 450 and component pickup instruction program (command) to component pickup control unit 440 are generated. The component accumulation program command is sent to the wagon / tray management & control means 450 and the component pickup control means 440.

  When processing each sheet processing program from the schedule operation unit 410, the component pickup control unit 440 performs control processing of the component pickup device 1250 based on the component extraction instruction program (command) and the component accumulation instruction program (command) of each component. . A specific control operation of the control process is to pick up the corresponding part from the sheet material being processed by the processing machine 1100, move it on the corresponding small parts collection station or the parts collection pallet, and accumulate it at the corresponding collection position.

  The wagon / tray management & control means 450 performs location management of the wagon / tray control device and control processing based on the wagon / tray component accumulation instruction program (command). A specific control operation of the control process is to move the tray between the layout wagon 1400 and the component stacking station 1310 by the tray changer unit 1320.

  The flow of various processes of the schedule operation unit 410 is as follows (see FIGS. 9 to 17).

  The schedule driving means 410 is composed of the following processing functions (see FIG. 2).

  The shelf / mold usage status collection process 411 is used for the status of material collection pallet / wagon usage and drilling for the material usage status and processed parts accumulation in the shelf used in the scheduled operation of the drilling / cutting cell. Collect the history of mold status.

  The details of the material / part shelf optimum management process will be described with reference to FIG. The material / part shelf optimum management process 412 is based on the material use history information collected in the shelf / mold use state collection process 411, and the average use interval, the number of use frequencies, and the average of each material for a certain period (eg, one week). The usage amount and the total usage amount are calculated (step S41201).

  The safety stock number is updated from the usage frequency number and the average usage amount of each material (step S41202).

  Based on the frequency of use and the average usage amount of the material, a determination process (step S41203) is performed to determine whether the material pallet is a single picking target material pallet or a material picking material pallet for single picking ST. That is, the high use frequency and the high use frequency are set as the single picking ST target material pallet, and the high use frequency and the low use rate are set as the single picking target material pallet.

  The rearrangement process of the storage address in the shelf is executed based on the frequency of use of the material pallet, and the material pallet having the high use frequency is redistributed to the shelf storage address close to the line loading position 1265 for the target material pallet after the preprocessing ( Step S41204).

  FIG. 10 shows a relationship between two schedule groups, that is, a processing schedule being executed and an added processing schedule. The current execution schedule is registered for the corresponding processing machine and represents the schedule that is being executed. The actual processing order is ascending order of No. The status of processing results indicates that processing has been completed, exactly being processed, or not yet started (not processed). In this example, No. 50 represents the latest machining schedule. The next machining schedule represents a schedule created by the automatic programming device 300 separately from the current execution schedule that is currently being machined.

  Details of the advance schedule determination processing 413 will be described with reference to FIGS. The pre-schedule determination processing 413 includes a target processing machine of a processing schedule (see FIG. 10) including the next processing schedule and the subsequent processing schedule (see FIG. 10) after the next processing schedule reading processing (step S41301) and the next processing schedule. The determination process of the arrangement and the arrangement in the shelf is performed (step S41302).

  Thereafter, in the material / part shelf allocation simulation check process (step S41303), the current execution schedule, the next processing schedule, the current material / part inventory information, and the sorting area information are referred to, and the material / part shelf allocation simulation is performed. I do.

  When the number of material safety stocks is insufficient or material replacement occurs, a necessary material pallet and unused material pallet replacement setup instruction or a necessary number of in-shelf arrangement (see FIG. 19) processing instruction (step S41304) is performed.

  In addition, in the shelf arrangement processing instruction (step S41304), the difference between the number of materials required for the processing schedule to be executed and the number of stocks in the shelf, and the safety stock number of the corresponding material for the material A that has become insufficient in safety stock. The in-shelf arrangement instruction is sent from the material packing to the material pallet (skid) A in the shelf.

  In addition, during the post-processing schedule operation process and the setup navigation process, according to the processing schedule order, the corresponding material sheets from the direct shelf (material A, material B) or the single material picking station 1285 (material C) are picked up one by one. Then, a processing / laying process (FIG. 18) is performed in which the material sheet is conveyed onto the shuttle table 1260 and the material pickup device 1250 supplies the material sheet to the processing machine 1100.

  In addition, when there is a shortage of component stacking pallets in the shelf, an instruction for securing an empty pallet is performed by taking out components from the processed component pallet. Alternatively, an instruction to temporarily remove an unused material pallet from the shelf and convert it to a parts pallet is issued (step S41305).

  Thereafter, a provisional allocation process request (step S41306) according to the purpose of use of the shelves (pallets) / wagons / trays for collecting the parts for all the sheet processing based on all schedules is sent to the shelves / wagons / tray distribution scheduling processing means 460.

  In response to this, the shelf / wagon / tray layout scheduling processing means 460 reads the corresponding sheet processing program and all parts data of the entire processing schedule (step S461). After that, a shelf / wagon / tray layout scheduling process for component accumulation is performed with the corresponding sheet processing program of the entire processing schedule (see FIG. 27).

  As a final process, the pre-schedule determination process 413 performs a process of adding the next machining schedule to the current execution schedule (step S41308).

  Details of the setup navigation processing 414 will be described with reference to FIG. The setup navigation process 414 (material / parts, distribution wagon entry / exit instruction) is based on the above-described pre-schedule determination process 413, various pallet exchange instructions in the schedule operation process, and distribution wagon exchange instruction. (Step S4401) is performed. In addition, a delivery wagon entry / exit instruction (step S41403) is performed. At that time, as the setup navigation processing 414, the screen of FIG. 20 is displayed (steps S41402 and S41404). On that screen, a parts delivery schedule list, a parts distribution wagon delivery schedule list, a stock chart on the parts collection pallet corresponding to the parts delivery schedule, and a parts information list on the parts collection pallet are displayed. The parts and distribution wagons that have been dispatched and replaced are displayed as navigation.

  The worker performs a delivery operation according to the navigation. At that time, the arrangement wagon entrance / exit 1330 (station) has a three-color indicator lamp 1340 (red blue yellow), and the state of the arrangement wagon 1400 is displayed (see FIG. 7). Depending on the situation (blue and yellow flashing simultaneously: wagon replacement instruction), the wagon is replaced and transported to the next process. When the item tag with ID tag on the screen is selected simultaneously with the delivery of the component from the component pallet, the item tag with ID tag is output. A product slip is attached to the delivered parts and transported to the next process. Further, a mold replacement setup instruction (step S41405) is performed based on the used mold replacement instruction in the advance schedule determination process 413.

  Details of the schedule operation processing 415 will be described with reference to FIGS. 15, 16, and 17. The schedule operation process 415 executes the following process. The schedule operation starting process (step S41501), the current execution schedule reading process (step S41502), the current execution schedule are prefetched, and the material / part shelf allocation simulation and the mold / laser head replacement simulation check process (step S41503) are performed. Do.

  Based on the result of the simulation check process (step S41503), an instruction for processing and arrangement in the shelf in the setup navigation process (step S41504) is performed.

  Based on the instruction and processing schedule, material / part pallet loading / unloading is executed. At the same time, the processing arrangement and the in-shelf arrangement process (step S41505) are performed.

  Further, as a corresponding cell control process (step S41506), processing by the sheet processing program is performed.

  If there is a mold / laser head replacement setup during the setup navigation process (step S41507), a setup instruction is issued. From A1 in FIG. 16, a shelf / wagon / tray serving scheduling processing request (step S41508) for component stacking in the corresponding sheet processing is sent to the shelf / wagon / tray serving scheduling processing means 460 to determine component wagon serving schedule information (step S41508). (See FIG. 27).

  From the determined parts wagon arrangement schedule information, a wagon / tray replacement instruction (step S41509) is output to the shelf / wagon / tray management & control means 450, and the wagon / tray replacement is executed (see FIG. 23).

  The details of the wagon / tray replacement process will be described with reference to FIG. Based on the layout schedule, the corresponding tray is searched (step S45001). Thereafter, the corresponding tray is reserved (step S45002) (tray reservation ON of wagon information). The corresponding tray is automatically moved to the accessory parts collection station (step S45003) (change of location information). It is confirmed whether or not the corresponding part can be stacked on the tray (step S45004) (one stacking considering quality, stacking of the same parts, weight limit, size limit).

  If stacking is possible (YES in step S45005), the components are stacked on the tray and inventory update (step S45006) is performed. A full stack check on the tray is performed (step S45007).

  When full (YES in step S45007), the full tray is returned to the wagon 1400 (step S45008) (change of location information). The next tray is searched (step S45009).

  If there is a next tray (YES in step S45010), the process proceeds to the corresponding tray reservation process (step S45002).

  If there is no next tray (NO in step S45010), it is checked whether all trays are full (step S45011).

  If it is full (YES in step S45011), an allocation process for the next empty wagon and an exchange instruction (step S45012) are performed from the empty wagon standby place. The full wagon state is set as full load display (step S45013), and a movement instruction to the standby place before bending (LED lighting) (step S45014) and actual movement work (step S45015) are performed (location change, LED off, usage status: not yet).

  In addition, a full tray check is performed, and if it is not full (NO in step S45007), the process proceeds to the end process of the corresponding schedule. When the schedule ends (YES in step S45016), as an end operation, an instruction to move the wagon to the waiting place before bending (step S45014) and a moving operation (step S45015) are performed.

  If the schedule does not end, continue processing.

The important thing here is that as long as there is an alternative empty wagon at the drilling / cutting empty wagon stand-by location, the wagon replacement can be continued without stopping the sorting and accumulating work during the scheduled operation of the drilling / cutting cell device. You can continue.

  In addition, each of the above-mentioned arrangement instructions gives a navigation instruction as an arrangement / conveyance setup on the display on the various control devices.

  In parallel with the wagon / tray replacement operation, based on the processing schedule from A2 in FIG. 17, the component pick-up control (step S41510) and the component accumulation instruction (step S41511) in the corresponding sheet processing are performed. Specifically, each component pickup information and component accumulation instruction information in the corresponding sheet processing is instructed to the component pickup control means 440 and the wagon / tray management & control means 450, the parts are picked up from the corresponding sheet, and the corresponding tray To collect.

  Each control means control processing 416 includes schedule operation means 410, shelf management & control means 430, component pickup control means 440, cell control means 420, wagon / tray management control means 450, shelf / wagon / tray serving scheduling processing means. Information control is performed between 460 and other general management devices.

  Note that the processes from the schedule reading process of A3 in FIG. 15 are repeatedly performed until all schedules are completed.

(3) Regarding the wagon management system processing with ID tag by the wagon integrated management device 500 (see FIG. 3) and the drilling / cutting cell integrated management device 400:
In the case of stacking by parts on a conventional parts stacking pallet (skid), there is a certain nesting unit group (sheet group) due to restrictions on the physical pallet stacking area and the number of pallets (3000 × 1500 mm × 3 pallets = 13.5 m 2). It was difficult to accumulate while continuously operating. Cannot be allocated due to frequent exchanges and a limited number of stacked pallets. In the case of small lots, nesting integration is performed even if integration is performed by parts. In particular, product family accumulation is not possible. For this reason, a plurality of nesting unit groups must be collected in advance to perform nesting integration operation.

After selecting and grouping the parts that can be stacked on the distribution wagon / tray by using the ID tag distribution wagon 1400, if the size of the component to be integrated is 600 × 600 mm or less, it is 600 × 600 mm. X38 trays x 3 wagons = 41 m ² can be secured, and if it is 600 x 600 mm or more or is not subject to various conditions for accumulation, sheet nesting that can be accumulated on that area can be performed on the component accumulation pallet (skid) side. . By extending the number of serving wagons 1400 with ID tags to a maximum of eight (the serving wagon entrance / exit 1330: 8 locations), an accumulation of about 110 m ² becomes possible. If necessary, replacement with an alternative empty wagon makes continuous processing longer.

  In addition, for parts with molding, parts without scratches, etc., the properties of the parts, the next process and the product unit are not grouped before nesting, and the shelf / wagon / tray distribution scheduling processing means 460 at the time of sheet processing is performed. On the wagon / tray management & control means 450 side, sorting and distribution can be performed while determining the accumulation conditions.

  In this component pickup device 1250 and the ID tag-attached distribution wagon / tray integrated distribution device 1300, if there are no restrictions such as scratches on the same component, the integration efficiency can be improved by integrating the same component in the same place. . At the same time, by delivering the component stacking trays to the four component stacking stations 1310, the processing stop time of the processing machine 1100 in the component pick-up & stacking process can be reduced as much as possible. This distribution wagon 1400 is transported to the next process, and direct automatic loading can be performed in the required processing order (product family configuration and multi-item batch mold setup order) in the processing machine of the next process (complete external setup) ).

(4) About the wagon management device 500:
The wagon integrated management device 500 is configured by each unit shown in a system block diagram (see FIG. 3). The wagon supervising management means 510 is the core of the wagon supervising management apparatus 500, and includes a wagon location information collection process 511, a wagon location information display process 512, a condition setting process 513 for each purpose of wagon use, a setup navigation process 514, and various controls / managements. It is comprised by the control process 515 between means. The wagon location information collection processing 511 collects location value information from each wagon / tray device by the wireless ID tag control means 520 via the wireless ID tag controller.

  Each control device control means 530 is configured to update the current material / parts inventory information and update each wagon / tray in synchronization with the operation of each control device after each wagon / tray device is loaded into and unloaded from each control device station. The notification process of the operating state of the device is executed.

  Each general management device control means 540 performs information exchange processing between the wagon general management device 500, the punching / cutting cell general management device 400, and the bending cell general management device 600.

  The wagon location information collection processing 511 collects location information, device status, and current material / part inventory information as wagon information of each wagon / tray device in real time.

  The wagon location information display processing 512 monitors and displays each piece of information (location, product inventory, device status) collected in the wagon location information collection processing 511.

  The shelf / wagon usage purpose condition setting processing 513 sets shelf / wagon usage purpose condition information (FIG. 26) for determining the usage purpose of the component stacking shelf / wagon / tray for all parts when the machining schedule is executed. To do. The shelf / wagon use purpose condition information includes all the shelves / wagon numbers, grouping conditions for shelves / wagons: by next process (processing machine), by production order (manufacturing number), by product, and by product family. Separate (optionally specified unit configuration), by delivery date, by nesting unit (one planned unit), by quality (quality level required for parts), tray number (for shelves, pallet or skid number, for wagons) , Tray number), tray grouping conditions: items similar to those for shelves / wagons, and these can be preferentially combined with a plurality of usage-specific conditions.

  The setup navigation processing 514 is the difference between the part process progress information, the current material / part inventory information, and the wagon location information (wagon collection / convey request from each cell / wagon management device, delay in process delivery, insufficient number of processing completions, (Synchronization delay of assembly parts in welding assembly) to perform scheduling processing for serving instructions for the corresponding wagon / tray device by each optimum layout transport schedule processing.

  The process progress information (see FIG. 21) includes basic data such as an order number, a product number, a product name, a part number, a part name, and the number of processed pieces for each manufacturing number, and each process (CAD / CAM, The scheduled process delivery date (date and time), performance information, etc. of drilling / cutting, secondary, etc. are managed. Current material / parts inventory information manages the location information (XY position) of each material / part stored on each pallet / wagon pallet / tray, loading status, manufacturing number, part number, inventory quantity, warehousing date, etc. To do.

  Also, the location information of the wagon includes the empty wagon waiting place (station) for drilling / cutting, the distribution wagon entry / exit 1/2/3 for the drilling / cutting process, the actual wagon waiting place before the bending process, and the bending process parts. There are a loading place, an empty wagon standby place after bending, a parts accumulation place in the bending process, an actual wagon waiting place before the welding process, a welding process parts loading place, and the like. The location information is managed by the reservation status of each wagon / tray in the wagon information, location information, the immediately preceding collection source, transport destination, scheduled transport time, and transport next process information.

  Details of the setup navigation processing 514 will be described with reference to FIG.

  First, it is determined whether there is a request for wagon collection / conveyance from each cell / wagon management device (step S 5401). If there is a wagon request (YES in step S 5402), a wagon reservation (step S 51403) and a wagon movement instruction (step S 51404) are performed.

  After that, as a setup navigation function, a conveyance delay check to the next process (steps S51405, S51406, S51407), a shortage check of parts inventory to be processed in the process schedule in the next process (steps S51408, S51409, S51410), welding / Synchronization delay check processing (steps S51411, S51412, S51413) of the assembly parts in the assembly process is performed.

[5] The ID tag-attached wagon management system process performed by the drilling / cutting cell overall management device 400 will be described.

  The component-by-component integration system in the perforating / cutting cell is composed of a component pickup device 1250, a distribution wagon / tray integrated distribution facility 1300 with an ID tag, and a distribution wagon 1400 with an ID tag (see FIGS. 4 and 6). ). In the case of schedule operation of the corresponding parts, there are three kinds of parts stacking / laying methods on each tray in accordance with the loading mode of each part: one-stage stacking / tray, multiple loading / tray of the same part, multiple loading / tray of the same part in FIG. There is a way.

  Further, when loading the corresponding parts on each tray 1350 in the wagon 1400, there is a load limitation as described in FIG. 8 depending on the shape (XY size and plate thickness, height after molding) of the corresponding parts and the number of stacked sheets. is there. There are tray size (600 × 600 mm), tray height (10 mm), and tray pitch interval (20 mm). When loading the relevant parts on the tray, it is necessary to perform an integrated arrangement considering the pitch limit between trays (20 mm) and the stack height limit (10 mm).

  In the pre-scheduling process 413 of the drilling / cutting cell overall management device 400, a provisional allocation scheduling request according to the purpose of use of the shelves / wagons / tray for collecting all parts of all sheets based on all schedules is sent to the shelves / wagon / It is sent to the tray distribution scheduling processing means 460 (see FIG. 13), and for the corresponding sheet processing and all part data of the entire processing schedule, the classification conditions (by next process (next processing machine), by product, by order, by quality, by nesting unit) All parts grouping (scheduling) information (see FIG. 25) is created based on the other.

  The all parts grouping information includes the shelf / wagon number, tray number (pallet or skid number in case of a shelf), stacking position of the corresponding part (manufacturing number, part number, product number, order number, next process: processing machine). (XY position and stacking order at the time of stacking), managing the number of stacks.

  In addition, at the time of processing the corresponding sheet of all parts grouping information and each processing schedule, shelves / wagon use purpose allocation condition information for determining the use purpose of parts collection shelves / wagons / tray of all products (see FIG. 26) Is created in advance in the shelf / wagon usage purpose condition information setting process 513.

  The shelf / wagon use purpose condition information includes all target shelves / wagon numbers, grouping conditions for shelves / wagons: by next process (processing machine), by manufacturing order (manufacturing number), by product, by product family ( Unit configuration specified arbitrarily), by delivery date, by nesting unit (one planned unit), by quality (quality level required for parts), tray number (pallet or skid number for shelves, tray for wagons) Number), grouping conditions for trays: items similar to those for shelves / wagons, and they can be preferentially combined with conditions for multiple purposes.

  In the schedule operation processing 415 (see FIG. 16) of the punching / cutting cell overall management device 400 (see FIG. 16), the component stacking shelf / wagon / tray serving scheduling processing request for the corresponding product of the corresponding sheet processing based on the reserved processing schedule (step) S41508) is sent to the shelf / wagon / tray serving scheduling processing means 460.

  As shown in FIG. 27, the shelf / wagon / tray arrangement processing means 460 reads the corresponding sheet processing program and all component data (step S461), and allocates the shelf / wagon / tray use purpose allocation scheduling process (step S462) (FIG. 28), allocation scheduling of the corresponding shelf / wagon / tray is performed (step S46202).

  Thereafter, in the corresponding shelf-pallet / wagon-tray selection stack position determination process (step S463) (see FIGS. 29 and 30), the following process is executed. Judgment of the loading mode of the corresponding part (single-sheet stacking mode: no high-quality scratches and when stacking cannot be performed with molded materials, multiple-sheet stacking mode: stacking high-efficiency operation without limiting stacking of one sheet) (step S46301, S4632) is performed.

  In the case of the multi-sheet stacking mode, the A1 process of FIG. 30 is performed.

  In the case of the single sheet stacking mode, the following processing is performed. The stacking position of the empty stacking area on the same shelf pallet and tray selected immediately before is selected. The placement process of the corresponding part (XY dimension) on the tray in the empty area is performed to secure the stacking position (step S46310). The placement process uses material sheet material placement logic in an automatic programming device. The presence / absence determination of the accumulation area is performed (step S46311).

  If there is an accumulation area (YES in step S46311), a limit stacking height check on the corresponding pallet and tray is performed (step S46316).

  If there is no stacking area (NO in step S46311), the stacking position of an empty stacking area of another shelf / tray in which the component stacking height (tray pitch) is secured is selected (step S46312). Thereafter, the presence / absence determination of the accumulation area is performed (step S46313).

  If there is an accumulation area (YES in step S46313), a limit stacking height check on the corresponding pallet and tray is performed (step S46316).

  If there is no stacking area (NO in step S46313), the stacking position of an empty stacking area of another shelf / tray where the component stacking height (tray pitch) is not secured is selected (step S46314). Thereafter, the presence / absence determination of the accumulation region is performed (step S46315).

  If there is an accumulation area (YES in step S46315), a limit stacking height check on the corresponding pallet and tray is performed (step S46316).

  If there is not (NO in step S46315), the process from A3 in FIG. 30 is performed to select the forced mixed loading process (step S46320) as the accumulation error process.

  If there is an accumulation area in the determination of the presence / absence of each accumulation area (YES in steps S46311, S46313, and S46315), a limit stacking height check on the corresponding pallet and tray is performed (step S46316).

  If the tray pitch is over (YES in step S46317), a space securing process (tray redistribution command) (step S46318) is performed on the upper tray of the corresponding tray of the corresponding wagon.

  If there is no tray pitch over (NO in step S46317), the process ends.

  In the multiple-sheet stacking mode process A1 in FIG. 30, a determination process (step S46330) for determining whether the stacking is performed by component or by stacking.

  In the case of stacking by part (YES in step S46330), the same stacking position as the pallet and tray on which the same part (manufacturing number, part number) is loaded is selected (step S46331).

  In the case of mixed stacking (NO in step S46330), a pallet and a tray on which different parts (manufacturing number and part number) permitted to be stacked and stacked are selected (step S46332). Thereafter, the presence / absence determination of the accumulation area is performed (step S46333).

  If there is an accumulation area (YES in step S46333), a limit stacking height check on the corresponding pallet and tray is performed (step S46340).

  If there is no stacking area (NO in step S46333), the stacking position of the empty stacking area of the same shelf / tray in which the component stacking height (tray pitch) is secured, and then the empty stacking area of another shelf / tray are displayed. One of the loading positions is selected (step S46334). Thereafter, the presence / absence determination of the accumulation region is performed (step S46335).

  If there is an accumulation area (YES in step S46335), a limit stacking height check on the corresponding pallet and tray is performed (step S46336).

  If not exceeded (NO in step S46337), the process ends.

  In the case of exceeding (YES in step S46337), the stacking position of the empty stacking area of the same shelf / tray in which the component stacking height (tray pitch) is secured, and the empty stacking area of another shelf / tray next to it are again displayed. A loading position is selected (step S46334). Repeat the same process.

  If there is no accumulation area in the determination of the presence or absence of the accumulation area (NO in step S46335), the stacking position of the empty accumulation area of the same shelf / tray where the component stacking height (tray pitch) is not secured, and the next One of the stacking positions of the empty stacking areas of the different shelves / trays is selected (step S46338). Thereafter, the presence / absence determination of the accumulation area is performed (step S46339).

  If there is an accumulation area (YES in step S46339), the limit stack height check on the corresponding pallet and tray is performed (step S46340).

  If there is no accumulation area (NO in step S46339), the process of A3 is performed.

  If the tray pitch is over (YES in step S46341), a space securing process (tray redistribution command) (step S46342) is performed on the upper tray of the corresponding tray of the wagon.

  If the tray pitch is not over (NO in step S46341), the process ends. As a result, the corresponding shelf-pallet and wagon-tray are selected and the loading position is determined, and wagon parts arrangement schedule information (see FIG. 31) is created.

  The wagon parts arrangement schedule information is the schedule information (sheet name, picking order, serial number, where the parts of each sheet processing program are arranged on which shelf / wagon pallet (skid) / tray at the time of sheet processing. (Part number, product number, order number, next process, shelf / wagon number, skid / tray number, stacking position, etc.) are managed. In addition, a tray redistribution instruction is given in the case of a part with molding (see FIG. 8). The process is performed for all parts of the corresponding sheet processing.

  The wagon part arrangement schedule information and the tray rearrangement instruction created by the shelf / wagon / tray arrangement processing means process are returned to the schedule operation process. On the schedule operation processing side (see FIG. 16), a wagon / tray replacement instruction is executed to the component stacking shelf / wagon / tray management & control means in the corresponding sheet processing based on the processing schedule, and the remaining processing is executed.

  The purpose of use (layout type) of each wagon / tray is determined in advance as the allocation condition information by shelf / wagon use purpose (see FIG. 26), and the purpose of use of each wagon / tray is determined based on the predefined contents. . The grouping conditions for these purposes include the following process (processing machine), production order, product, product family unit, delivery date, nesting unit & quality (1 product pickup order), etc. These conditions can be assigned to wagons / trays.

However, when the purpose of use of each wagon / tray is determined based on the shelf / wagon use purpose allocation condition information, the grouping conditions may not be met and each wagon / tray may not be allocated. As an example, each wagon is operated according to the next process, but there are 3 wagon entry / exit entrances: 3 wagons, but there are more than 4 types of next process, the current 3 parts for the 4th process part Unable to reserve wagons that are currently being shipped. Therefore, as an exception process, forced allocation is performed on the component stacking pallet 1275 (see FIG. 4) .

  Next, a typical arrangement schedule operation example of the component accumulation arrangement on the tray in the wagon between the drilling / cutting cell process and the bending process will be described with reference to FIG.

  As for the allotment type, each wagon is assigned to the next process machine (2 locations at the entrance and exit of the distribution wagon: for A-bending automatic cell ASTRO, 1 location: for bending general-purpose machine HDS), so that it can be assembled in the order of production order A plurality of parts are arranged (a plurality of parts are loaded) (see FIG. 32).

  In this case, the arrangement efficiency on the tray is increased.

  As a specific operation, the production plan includes three types of products S1 × 1 (component P1-P8), S2 × 1 (component P11-P17), and S3 × 1 (component P31-34). In the case of instructing processing of one family, if a material sheet processing program is created using the material sheet nesting system, these are three types of material sheet processing programs Sh1, Sh2, and Sh3.

  When this is processed by a punch laser complex machine and a catering process is performed, it is as shown in FIG. This distribution wagon is transported to the bending automation cell and bending general-purpose machine in the next process. After that, the bending automation cell side considers the processing order of production of one product family, and also considers the schedule order (tray TR-1-1-1 to TR-1-6 of wagon # 1) in consideration of the mold exchange setup time and the like. P8, P16, and P34, which are accumulated in the trays TR-3-1 to TR-3-3 of the wagon # 3 and exceed the tray loading size, are accumulated on the component accumulation pallet (skid). Automatic parts supply from the catering wagon / tray device can be realized without manual setup for preparation.

  As another arrangement type, in the case of arrangement in consideration of the quality of parts, each wagon is assigned to each next process machine, and one part is arranged in one tray in the order of picking up one part by the parts pick-up device (no multiple loading). There is also a method.

  Other examples of serving scheduling processing include the following cases.

  Production plans include products A, B, C, and D (see FIG. 21).

  Product A is composed of three types of parts A1, A2, A3, material name SPC1.0, and process information for each. The product B includes two types of parts B1 and B2, material names SPC2.0 and SPC1.0, and process information of each. Product C is composed of one type of component C1, material name AL1.2, and process information for each. The product D is composed of four types of parts D1, D2, D3, D4, material names AL1.2, SPC2.0, and respective process information.
