  FIG. 1 is a schematic diagram showing an entire modeling management system including a model order receiving management control device 14 according to the present embodiment.

  A model order receiving management control device 14 is connected to the communication line network 10 via a network I / F 12.

  The communication line network 10 is, for example, a LAN (Local Area Network) or an Internet line, and a plurality of LANs may be connected to each other by a WAN (Wide Area Network). Also, all communication line networks including the communication line network 10 do not have to be wired connections. That is, a part or all of the wireless communication network may transmit and receive information wirelessly.

  The molded article order management control device 14 has a main body 16 and a UI (user interface) 18. The UI 18 includes a monitor 20 as a display unit, and a keyboard 22 and a mouse 24 as input operation units.

  The main body 16 is connected to a media reader 26 that functions as an input source of ordering information necessary for ordering the modeling.

  The media reader 26 is provided with a slot portion into which a recording medium 30 such as an SD memory card can be inserted, for example, and the order information recorded on the inserted recording medium is read and sent to the main body 16.

  The ordering information may be received from the ordering PC 28 connected to the communication network 10 via the network I / F 12.

  As shown in FIG. 2, the main body 16 of the model order management control apparatus 14 includes a CPU 16A, a RAM 16B, a ROM 16C, an input / output unit 16D (I / O 16D), and a bus 16E such as a data bus or a control bus for connecting them. ing.

  As described above, the network I / F 12, the UI 18 (the monitor 20, the keyboard 22, and the mouse 24) and the media reader 26 are connected to the I / O 16D.

  Further, a hard disk 34 as a large-scale recording medium is connected to the I / O 16D. The hard disk 34 forms a plurality of three-dimensional modeling apparatuses 36 (1), 36 (2),... Based on information (in this embodiment, order management information) regarding received modeling orders and the order management information. -Information necessary for the allocation process for allocation to 36 (n) (information regarding a schedule to be described later) is temporarily stored. The three-dimensional modeling apparatuses 36 (1), 36 (2)... 36 (n) will be described later.

  A program for modeling order management control is recorded in the ROM 16C. When the model receiving order management control device 14 is activated, the program is read from the ROM 16C and executed by the CPU 16A. The modeling image management control program may be recorded on the hard disk 34 or another recording medium in addition to the ROM 16C.

  As shown in FIGS. 1 and 2, a plurality of three-dimensional modeling apparatuses 36 (1), 36 (2)... 36 (n) are connected to the communication network 10. Hereinafter, the three-dimensional modeling apparatuses 36 (1), 36 (2)... 36 (n) are collectively referred to as “three-dimensional modeling apparatus 36” or “3D printer 36”. The three-dimensional modeling apparatus 36 may be directly connected to the modeled object order management control apparatus 14 via a dedicated signal line.

  The three-dimensional modeling apparatus 36 may have the same modeling method of the modeled object, or may mix a plurality of different types of three-dimensional modeling apparatuses 36.

  Examples of the modeling method include a liquid layer photopolymerization method, a binder injection method, a material extrusion method, a material injection method, a sheet lamination method, a powder bed fusion method, and a directional energy deposition method.

  In FIG. 1, although an example of the external appearance of the three-dimensional modeling apparatus 36 is shown, the three-dimensional modeling apparatus 36 indicates the modeling method, the range of the size of a modeled object that can be modeled, and the type of material (filament) to be applied. Depending on the elements it contains, its appearance and size vary.

  1 and 2, three three-dimensional modeling apparatuses 36 are illustrated, but two or four or more types of three-dimensional modeling apparatuses 36 may be connected and selectable depending on an object to be modeled. Good.

  In the three-dimensional modeling apparatus 36, materials (materials) that can be adapted for modeling differ depending on the type of each modeling method.

Below, an example of the relationship between the kind of modeling method and the adaptive material of each modeling method is shown (modeling method ... applicable material).
(1) Liquid layer photopolymerization method ... UV curable resin (2) Binder injection method ... Gypsum, ceramics, sand, calcium, plastic (3) Material extrusion method ... ABS (acrylonitrile butadiene styrene Resin), PLA (polylactic acid), nylon 12, PC (polycarbonate), PPSF (polyphenylsulfone)
(4) Material injection method: UUV curable resin, fat, wax, solder (5) Sheet lamination method: Paper, resin sheet, aluminum sheet (6) Powder bed fusion bonding method: Engineering plastic, nylon, Metal (7) Directive energy deposition method: Metal Each specification of the three-dimensional modeling device 36 (including the modeling methods (1) to (7) and applicable materials) is a modeling device specification database 56 (described later). (See FIG. 3).

  By the way, in the modeled object order management control device 14, when an order is received for a three-dimensional modeled object, the time required for modeling differs depending on, for example, modeling information to be ordered (shape, size, material, additional function, etc.). In addition, there are cases where the operation status of the three-dimensional modeling apparatus 36 at the time of ordering is affected.

  Furthermore, depending on the density of orders, the modeling time is different between when modeling alone and when performing so-called ganging processing (processing of simultaneously modeling a plurality of modeling objects with a single three-dimensional modeling apparatus 36) (modeling form). Different.

  For reference, FIG. 4 is a characteristic diagram showing the relationship between the number (body) of modeling objects to be modeled simultaneously and modeling time. In FIG. 4, the shaped objects have the same shape.

  The characteristic diagram indicated by the dotted line A in FIG. 4 is the modeling time when the single modeling is performed, and is naturally a multiple of the modeling time of one modeled object.

  On the other hand, the characteristic diagram indicated by the solid line B in FIG. 4 is the modeling time when simultaneous modeling (ganging) is performed, and it can be seen that the modeling time is shortened in a quadratic curve as the number of simultaneous modeling increases.

  As described above, the modeling time varies depending on the modeling information, the operation status of the three-dimensional modeling apparatus 36, and the elements including the modeling form.

  Therefore, in the model order management control apparatus 14 of the present embodiment, when there are a plurality of orders (hereinafter sometimes referred to as jobs) in an environment where a plurality of three-dimensional modeling apparatuses 36 can be applied, It is determined in advance which 3D modeling apparatus 36 is assigned, and management control (schedule management control) for creating an optimal schedule (for example, a schedule in which the modeling end time of all jobs is the shortest) is constructed.

  FIG. 3 relates to the present embodiment, and is a schedule for assigning a plurality of received orders to a plurality of three-dimensional modeling apparatuses 36, which is executed by the main body 16 (see FIG. 2) of the model receiving order management control apparatus 14. It is a functional block diagram which shows the process for performing management control in detail. Note that FIG. 3 does not limit the hardware configuration of the molded article order management control device 14.

  The accepting unit 50 shown in FIG. 3 accepts modeling orders from various places including the media reader 26 and the ordering PC 28. The modeling order is an order when the reception unit 50 is the main component.

  The accepting unit 50 collectively accepts orders from each place and sends order information based on the orders from each place to the order management information creating unit 52. The order management information creation unit 52 sends the design information for modeling, among the information included in the order information, to the modeling time calculation unit 54.

  The modeling time calculation unit 54 acquires the specifications (specs) of the three-dimensional modeling apparatus 36 from the modeling apparatus specification database 56, and calculates the single modeling time a when modeling alone, based on the design information. The modeling apparatus specification database 56 is a specification updated to the latest information every time the apparatus is installed, discarded, upgraded, etc. by the modeling apparatus management unit 58 that collectively manages the modeling processing control of the three-dimensional modeling apparatus 36. Is memorized.

  The single modeling time a may be a guideline, and may be calculated from the design information and predicted from a predetermined volume-modeling time correlation diagram without obtaining from the modeling apparatus specification database 56, for example. .

  The single modeling time a calculated by the modeling time calculation unit 54 is sent to the order management information creation unit 52.

  The order management information creation unit 52 creates information for management as a job based on the order information and the single modeling time a. The order management information includes a job ID, submission time, design information, a single modeling time a, and a special note.

  The special remarks are a general term for individual requests and designations from the ordering side, such as information on delivery date (emergency request, modeling time designation), information on modeling method and material, and the like.

  The order management information creation unit 52 is connected to the temporary storage unit 60 and sends the created order management information to the temporary storage unit 60. The temporary storage unit 60 temporarily stores the received order management information.

  The temporary storage unit 60 is connected to the extraction time determination unit 62, and sends order reception status information to the extraction time determination unit 62 every time the order management information is acquired.

  The extraction time determination unit 62 acquires the operating status of the three-dimensional modeling apparatus 36 from the modeling apparatus management unit 58 and determines whether it is time to extract order management information for setting a modeling schedule.

  The extraction time determination unit 62 instructs the extraction unit 64 to extract order management information.

  The extraction unit 64 is connected to the temporary storage unit 60, and extracts order management information targeted for modeling schedule management from the temporary storage unit 60 based on an extraction instruction from the extraction time determination unit 62.

  A plurality of (job count J) order management information extracted by the extraction unit 64 is sent to the schedule creation unit 66 and the submission-shipment period calculation unit 68.

  In the submission-shipment period calculation unit 68, the submission waiting period stored in the submission waiting period information storage unit 70 and the shipment preparation period stored in the shipment preparation period information storage unit 72 are considered to be sent out. The period up to (the submission-shipment period b) is calculated and sent to the schedule creation unit 66.

  In addition, the schedule creation unit 66 acquires the number of applicable three-dimensional modeling apparatuses 36 (the number of apparatuses N) from the modeling apparatus management unit 58. As a result, in addition to the order management information, the number of jobs J, the number of devices N, and the submission-shipping period b are input to the schedule creation unit 66.

Here, the combination of executing the modeling of a plurality of jobs (number of jobs J) by the plurality of 3D modeling apparatuses 36 (number of apparatuses N) is N to the power of J (= N ^J ) (see Table 1). . In the combinations shown in Table 1, all jobs can be modeled by all three-dimensional apparatuses 36, and as an extreme example, all jobs can be modeled (ganged) simultaneously by a single three-dimensional modeling apparatus 36. Is a combination including As shown in the thick frame in Table 1, in the example of two devices (device number N = 2) and three jobs (job number J = 3), there are eight schedules (N ^J = 2 ³ ). It becomes a combination.

  Further, the number of combinations is not limited to the range shown in Table 1, but may be eight or more three-dimensional modeling apparatuses 36, or may be ten or more jobs.

As shown in FIG. 5, the schedule creation unit 66 sets schedule tables 74 (1) to (n) for all combinations. In the schedule table 74, the job name is set as the item 74A, the single modeling time a as the item 74B, the device (name) as the item 74C, and the submission-shipping period b as the item 74D.

  Further, in each schedule table 74, as an item 74E, the ratio (b / a) between the single modeling time a and the submission-shipping period b in each job is calculated and written.

  All the ratios b / a in each calculated schedule are summed, and the total ratio b / a (Σ {b / a}) is calculated for each schedule (see item 74).

  As shown in FIG. 3, the schedule creation unit 66 is connected to the selection unit 76. In the selection unit 76, the schedule table 74 (x) that is the minimum value among the items 74F (Σ {b / a}) of all the schedule tables 74 (1) to (n) created by the schedule creation unit 66 is selected. select. Note that x represents one of 1 to n in parentheses for identifying the schedule table 74.

  The schedule in which Σ {b / a} is the minimum value indicates that the finish time of the modeling process for all jobs is the shortest time.

  The selection unit 76 is connected to the job allocation unit 78. The job allocation unit 78 instructs the modeling apparatus management unit 58 to allocate each job to the three-dimensional modeling apparatus 36 based on the selected schedule table 74 (x).

  In the modeling apparatus management part 58, the 3D modeling apparatus 36 is controlled and a modeling process is performed according to the schedule table 74 (x).

  The operation of the present embodiment will be described below with reference to the flowcharts of FIGS.

  FIG. 6 is a flowchart showing the flow of job assignment control executed by the model order management control device 14.

  In step 100, it is determined whether or not an order (job) for a model has been received from the network I / F 12, the media reader 26, or the ordering PC 28. If an affirmative determination is made, the process proceeds to step 102 to receive order management information. And move to step 104. The order management information includes a job name (ID), submission time, design information, single modeling time a, and special notes.

  In step 104, the order management information created in step 102 is temporarily stored, and the process proceeds to step 106. On the other hand, if a negative determination is made in step 100, the process proceeds to step 106.

  In step 106, the reception information is confirmed, and the process proceeds to step 108 to determine whether it is a schedule creation time. If a negative determination is made in this step 108, it is determined that it is not the schedule creation time, this routine ends, and the next job is awaited.

  If an affirmative determination is made in step 108, it is determined that it is the schedule creation time, and the routine proceeds to step 110.

  In step 110, order management information of a job (target job) to be scheduled for execution is extracted from the temporary storage unit 60 (see FIG. 3), and then the process proceeds to step 112 to acquire necessary information. The process proceeds to step 114. The necessary information in step 112 is submission time information, submission waiting period, and shipping preparation period.

  In step 114, based on the order management information and necessary information, a period from submission to dispatch of each job (submission-shipment period b) is calculated, and the process proceeds to step 116.

  In step 116, necessary information is acquired, and the process proceeds to step 118. The necessary information in step 116 is the number of devices N, the number of jobs J, the single modeling time a, and the submission-shipping period b.

In step 118, schedule tables 74 (1) to 74 (n) (see FIG. 5) are created. The number of schedule tables 74 (1) to 74 (n) is determined by the number of devices N and the number of jobs J, and schedule tables of N to the power of J (= N ^J ) are created. Each schedule table 74 includes a job name as item 74A, a single modeling time a as item 74B, a device (name) as item 74C, and a submission-shipping period b as item 74D, and an item 74E as each job. The result of calculating the ratio (b / a) between the single modeling time a and the submission-shipping period b is written.

  Further, each schedule table 74 (1) to 74 (n) is set with an item 74F, and all the ratios b / a in each calculated schedule are totaled, and the total ratio b / a is calculated for each schedule. The result of calculating a (Σ {b / a}) is written.

As shown in FIG. 6, in the next step 120, from the schedule table 74 of N ^J Street created, to select an optimal schedule.

  That is, in step 120, the schedule table 74 (x) that is the minimum value among the items 74F (Σ {b / a}) of all the schedule tables 74 (1) to (n) created by the schedule creation unit 66. Select. x indicates any one of 1 to n in parentheses for identifying the schedule table 74.

  The schedule table 74 (x) in which Σ {b / a} is the minimum value indicates that the end time of the modeling process for all jobs is the shortest time.

  In the next step 122, a job is assigned to the 3D modeling apparatus 36 based on the selected schedule table 74 (x), and then the process goes to step 124 to assign a job to each 3D modeling apparatus 36. This routine is finished.

  FIG. 7 shows a control routine for execution of modeling in the three-dimensional modeling apparatus 36.

  In step 150, it is determined whether or not a modeling instruction has been given. If a negative determination is made, this routine ends. If an affirmative determination is made in step 150, the process proceeds to step 152, the allocation information executed in step 122 in FIG. 6 is acquired, and the process proceeds to step 154.

  In step 154, a job is assigned to each 3D modeling apparatus 36, and then the process proceeds to step 156 to instruct the start of modeling by each 3D modeling apparatus 36, and the process proceeds to step 158. Each three-dimensional device 36 executes a modeling process of a modeled object based on an independent drive control system.

  In step 158, it is determined whether or not the modeling process has been completed in all the three-dimensional modeling apparatuses 36. If an affirmative determination is made, the process proceeds to step 160, and the modeling apparatus management unit 58 performs the process for each three-dimensional modeling apparatus 36. The modeling history is stored in step 162, and the process proceeds to step 162.

  In step 162, dispatch of the modeled object whose modeling has been completed is arranged, and this routine ends.

  In the present embodiment, the selection unit 76 (see FIG. 3) selects the schedule with the shortest modeling time from all the combinations (schedules), but the modeling history is taken into account. Then, the schedule may be selected.

  That is, as shown in FIG. 3, a modeling history storage unit 80 (illustrated by a dotted frame in FIG. 3) that extracts and stores a modeling history from the modeling apparatus management unit 58 is provided.

  The modeling history storage unit 80 is connected to the selection unit 76, and when the selection unit 76 selects a schedule, if there is an identical or similar combination (schedule) in the history, the selection is preferentially selected. To do. In this case, the selection processing time in the selection unit 76 is shortened, and since the schedule has a history, it is possible to increase the reliability compared to selecting a schedule without a history.

  Further, in the present embodiment, the schedule with the shortest modeling period is selected, but the selection target is given with priority given to the combination planning in which the height difference of the completed model is within a predetermined range. It is good. This is because the smaller the difference in height of the shaped object, the more advantageous for ganging.

  Furthermore, in the present embodiment, the schedule with the shortest modeling period is selected. However, when the delivery date is specified as a special note, the job within the range in which the difference in the specified delivery date is determined in advance. The combined schedule may be preferentially selected.

  FIG. 8 shows an example of job assignment control (scheduling) executed under a specific number of devices N and a specific number of jobs J in the model object order management control device 14 of the present embodiment.

The present embodiment is a combination of two devices (the number of devices N = 2) and three (the number of jobs J = 3), and as shown in Table 1, there are eight schedules (= 2 ³ ). FIG. 8 shows the schedule tables 74 (1) to 74 (8).

  FIG. 8 shows a modeling timing chart corresponding to the right side of the schedule tables 74 (1) to (8).

  The period of the hatched rectangular frame shown in FIG. 8 is a period during which the 3D modeling apparatus 36 is processing the previous job and cannot be processed immediately even if there is a submission (black dot).

  The period of the white rectangular frame shown in FIG. 8 is a modeling period including ganging.

  As an example, in the schedule table (2), two jobs are ganged by the apparatus A, and one job is single-modeled by the apparatus B. For this reason, in apparatus A, it is processed in 0.9 times of time rather than performing single modeling (see FIG. 4), and in apparatus B, it is processed in single modeling time a.

  Considering the submission waiting period indicated by the dotted right triangle and the preparation period for sending indicated by the dotted left triangle according to the timing chart in FIG. 8, the period from submission (black circle point) to shipment (white circle point) (submission-shipment period) b) is obtained.

  In each of the schedule tables 74 (1) to 74 (8), the total b = a (= Σ {b / a}) of each job is calculated, and the minimum value is selected. That is, in FIG. 8, in the schedule table 74 (4), the sum of b / a becomes the minimum value (Σ {b / a} = 8.1), and the schedule table 74 (4) is selected. That is, in this embodiment, the schedule table 74 (4) becomes the schedule table (x).

  Comparing the timing charts of the schedule tables 74 (1) to 74 (8), it can be seen that the schedule table 74 (4) is processed in the shortest time.
