Can be done. As a result, an efficient molded product can be formed.

An information processing apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing the configuration of the information processing apparatus according to this embodiment. 1, the information processing apparatus 10 according to the present embodiment includes a required information storage unit 11, a tact time information storage unit 12, a required expansion unit 13, a priority order calculation unit 14, a required allocation unit 15, and an output. Part 16.

  The required information storage unit 11 stores a plurality of required information. Here, the required information is information that associates molded product identification information, which is information for identifying a molded product, with the required number of the molded products. The molded product is formed by an injection molding machine. The required number is the number of molded products molded by an injection molding machine. The process in which a plurality of required information is memorize | stored in the required information storage part 11 is not ask | required. For example, a plurality of required information may be stored in the required information storage unit 11 via a recording medium, and a plurality of required information transmitted via a communication line or the like is stored in the required information storage unit 11. Alternatively, a plurality of required information input via the input device may be stored in the required information storage unit 11. The required information storage unit 11 can be realized by a predetermined recording medium (for example, a semiconductor memory, a magnetic disk, an optical disk, etc.). The storage in the required information storage unit 11 may be temporary storage using a volatile memory or the like, or may not be so. In the former case, for example, it may be temporary storage of necessary information read out by accessing a predetermined server or the like.

  The tact time information storage unit 12 stores tact time information. Here, the tact time information is the tool identification information that is information for identifying the tool, the molded product identification information of the molded product that is molded using the tool, and the tool that is identified by the tool identification information. Tact that indicates the time for molding the molded product identified by the molded product identification information using the injection molding identification information, which is information for identifying the injection molding machine on which the tool can be mounted, and the tool identified by the jig tool identification information This is information that associates time. Jigs and tools are used in injection molding in injection molding machines. For example, dies, nesting of dates and serial numbers attached to molds, transfer of molded products after injection molding to the next process, etc. A machine (Transfer Machine) or the like. In this embodiment, a case where the tool is a mold will be described. Therefore, the tool identification information may be referred to as mold identification information. The process in which the tact time information is stored in the tact time information storage unit 12 does not matter. For example, tact time information may be stored in the tact time information storage unit 12 via a recording medium, and tact time information transmitted via a communication line or the like is stored in the tact time information storage unit 12. Alternatively, the tact time information input via the input device may be stored in the tact time information storage unit 12. The tact time information storage unit 12 can be realized by a predetermined recording medium (for example, a semiconductor memory, a magnetic disk, an optical disk, etc.). The storage in the tact time information storage unit 12 may be temporary storage by a volatile memory or the like, or may not be so. In the former case, for example, it may be temporary storage of tact time information read out by accessing a predetermined server or the like.

  The required information storage unit 11 and the tact time information storage unit 12 may be realized by the same recording medium. In that case, the area storing the required information becomes the required information storage unit 11, and the area storing the tact time information becomes the tact time information storage unit 12.

The required expansion | deployment part 13 allocates required information to the injection molding machine which can be allocated. Therefore, the required expansion | deployment part 13 does not allocate required information to the injection molding machine which cannot be allocated. For example, when the required product information includes the molded product identification information “N001” and it is necessary to use the mold A to mold the molded product identified by the molded product identification information “N001”. Therefore, the required information is not assigned to an injection molding machine that cannot mount the mold A. Moreover, assigning the required information to the injection molding machine means that it is sufficient that at least the injection molding machine can be associated with the required information. Therefore, assigning the required information to the assignable injection molding machine is, for example, creating a new required information record including the injection molding identification information of the injection molding machine for each assignable injection molding machine. Alternatively, it is possible to simply associate the injection molding identification information of the assignable injection molding machine with the required information. The allocation of the required information by the required expansion unit 13 is a temporary allocation that allocates the required information to the injection molding machine that can be allocated, unlike the final allocation by the required allocation unit 15 described later. In the information processing apparatus 10 according to the present embodiment, provisional assignment is performed by the required expansion unit 13, and priority information is calculated by a priority calculation unit 14 to be described later for the necessary information on which the provisional assignment has been performed. Based on the ranking, the final allocation is performed by the required allocation unit 15.

  Based on the required information and the tact time information, the priority calculation unit 14 calculates the priority for each injection molding machine with respect to the required information assigned to the two or more injection molding machines by the required development unit 13. “Based on the required information and the tact time information” is based on, for example, the required information stored in the required information storage unit 11 and the tact time information stored in the tact time information storage unit 12. Alternatively, it may be based on information generated by the required developing unit 13 assigning the required information to the injection molding machine. In the present embodiment, the latter case will be described. Further, “calculating the priority for each injection molding machine with respect to the required information assigned to two or more injection molding machines by the required development unit 13” means, for example, that the required information provided by the required development unit 13 is the first injection. When assigned to the molding machine, the third injection molding machine, and the fourth injection molding machine, the priority order of the required information is set to be the highest priority order of the required information assigned to the third injection molding machine. Thus, the priority of the required information assigned to the fourth injection molding machine is the next highest, and the priority of the required information assigned to the first injection molding machine is the lowest. By calculating the priorities in this manner, the required allocation unit 15 can allocate the required information based on the priorities. How the priority calculation unit 14 calculates the priority will be described later.

  The required allocation unit 15 allocates the required information to any one of the injection molding machines based on the calculation result by the priority order calculation unit 14. Here, assigning the required information to the injection molding machine is associating the required information with the injection molding machine on a one-to-one basis, as described above. As a result of this assignment, it is determined with which injection molding machine the molded product indicated by the molded product identification information of the required information is molded.

  The output unit 16 outputs allocation information that is information indicating the result of allocation by the required allocation unit 15. The allocation information may be any information as long as it is information that allows the user to know which injection molding related to which required information is performed with which injection molding machine. For example, the information may be information that associates the required information with an injection molding machine that performs injection molding of the required information, or may be information in another format. Here, the output may be, for example, display on a display device (for example, a CRT or a liquid crystal display), transmission via a communication line to a predetermined device, printing by a printer, or audio output by a speaker. However, it may be stored in a recording medium. The output unit 16 may or may not include an output device (for example, a display device or a printer). The output unit 16 may be realized by hardware, or may be realized by software such as a driver that drives these devices.

Next, the operation of the information processing apparatus 10 according to the present embodiment will be described using the flowchart of FIG.
(Step S <b> 101) The required expansion unit 13 reads the required information from the required information storage unit 11.

(Step S <b> 102) The required development unit 13 reads the tact time information from the tact time information storage unit 12.
(Step S103) The required development unit 13 assigns the required information to the assignable injection molding machine based on the read required information and tact time information. In addition, at the time of assignment by the required developing unit 13, the priority order of the peers may be associated in advance with each piece of required information assigned to the assignable injection molding machine.

  (Step S104) The priority order calculation unit 14 calculates the priority order so that die switching is reduced and overall efficiency is improved. Details of this process will be described later.

  (Step S105) The priority order calculation unit 14 determines whether there is a peer in the priority order calculated in step S104. If there is a peer priority, the process proceeds to step S106, and if not, the process proceeds to step S107.

  (Step S106) The priority order calculation unit 14 calculates the priority order so that required information is assigned to an injection molding machine with a small load. Details of this process will be described later.

(Step S107) The required allocation unit 15 allocates the required information to the injection molding machine based on the priority calculation result by the priority calculation unit 14.
(Step S <b> 108) The output unit 16 outputs allocation information indicating the allocation result by the required allocation unit 15. Then, the process ends.

FIG. 3 is a flowchart for explaining in detail the processing in step S104 of the flowchart of FIG.
(Step S201) The priority calculation unit 14 sets the counter I to “1”.

  (Step S202) The priority order calculation unit 14 determines whether or not the I-th required information among the plurality of required information stored in the required information storage unit 11 is assigned to two or more injection molding machines by the required expansion unit 13. to decide. If it is assigned to two or more injection molding machines, the process proceeds to step S203, and if not, the process proceeds to step S206.

(Step S203) The priority order calculation unit 14 calculates the total number of injections for the I-th required information assigned to two or more injection molding machines. Here, calculation of the total number of injections will be described. The priority order calculation unit 14 first pays attention to the required information assigned to one injection molding machine by the required expansion unit 13 among the I-th required information. Next, the priority order calculation unit 14 is required information allocated to the same injection molding machine as the required information of interest among all the required information allocated to each injection molding machine by the required development unit 13. Then, the total number of injections of the required information using the same mold as the required required information is calculated. It is assumed that the total number of injections includes the number of injections of the target allocation. Here, in the present embodiment, it is assumed that the number of injections is the same as the required number. Therefore, the total number of injections is the total required number. Note that the number of injections may not be the same as the required number. For example, when two or more molded articles are formed by one injection, or when one or more molded articles are formed by two or more injections. In that case, the number of injections required to mold the required number of molded products is calculated. For example, when two molded products are molded by one injection, the number of injections is half of the required number. If the number of injections is not the same as the required number, for example, information indicating how many molded articles can be molded in one injection is associated with the mold identification information in the tact time information etc. It shall be retained. In addition, when molding one molded article by two injections, the operation of the two injections is regarded as one injection, and the total operation time of the two injections may be used as the tact time. . In that case, the number of injections and the required number are the same. The priority order calculation unit 14 similarly performs the process of calculating the total number of injections for the I-th required information assigned to other injection molding machines.

  (Step S204) The priority order calculation unit 14 determines whether there is the same number of injections regarding the allocation of the I-th required information calculated in Step S203. If there is an identical item, the process proceeds to step S205. If there is no identical item, the process proceeds to step S206.

  (Step S205) The priority order calculation unit 14 calculates an injection time for each allocation of the I-th required information. Here, the injection time is the product of the tact time and the required number. The calculation of the injection time may or may not be performed only for the assignment determined in step S204 that the total number of injections is the same.

  (Step S206) The priority order calculation unit 14 calculates the total number of injections calculated in step S203 and the step S205 if necessary for the I-th required information assigned to two or more injection molding machines. The priority order is calculated based on the injection time. Specifically, the priority order is calculated so that the required information having a larger total number of injections has a higher priority order. If the total number of injections is the same, the priority order is calculated so that the required information with a shorter injection time has a higher priority order. The calculation of the priority order based on the injection time includes changing the priority order calculated in advance. If the difference in injection time is within a predetermined threshold value, the priority order may not be calculated based on the injection time. In this embodiment, it is assumed that such a threshold is not set. Further, when the I-th required information is assigned to only one injection molding machine by the required developing unit 13 (that is, “No” in step S202), the priority order calculated in the other required information Among them, the same priority order as the highest priority order is calculated as the priority order of the required information assigned only to that one injection molding machine.

  Here, the principle of calculating the priority order will be briefly described. Of the required information assigned to two or more injection molding machines, by increasing the priority of the required information with the larger total number of injections, requirements for using the same mold for one injection molding machine are gathered. It can be easy. As a result, it is considered that the number of times of mold switching can be reduced and the molded product can be efficiently molded. In addition, by increasing the priority of the required information with the shorter injection time, the requirements can be easily gathered in an injection molding machine that can perform molding in a shorter time, that is, an injection molding machine with higher capacity. be able to. As a result, it is considered that the molded product can be efficiently molded as a whole.

(Step S207) The priority calculation unit 14 determines whether or not the I-th required information is the last required information. If it is the last required information, the process ends. If not, the process proceeds to step S208.
(Step S208) The priority calculation unit 14 increments the counter I by “1”. Then, the process returns to step S202.

FIG. 4 is a flowchart for explaining in detail the processing in step S106 of the flowchart of FIG.
(Step S301) The priority order calculation unit 14 sets the counter I to “1”.

  (Step S <b> 302) The priority order calculation unit 14 determines whether one or more priorities calculated for the I-th required information stored in the required information storage unit 11 are equivalent. If there is a peer priority, the process proceeds to step S303, and if not, the process proceeds to step S308.

  (Step S303) The priority calculation unit 14 calculates the total injection time for the I-th required information assigned to two or more injection molding machines. Here, calculation of the total injection time will be described. The priority order calculation unit 14 first pays attention to the required information assigned to one injection molding machine by the required expansion unit 13 among the I-th required information. Next, the priority order calculation unit 14 is required information allocated to the same injection molding machine as the required information of interest among all the required information allocated to each injection molding machine by the required development unit 13. Then, the total injection time of the required information using a mold different from the required required information is calculated. In addition, as the injection time of each required information, the time calculated in step S205 of the flowchart of FIG. 3 may be used. The calculation of the total injection time may or may not be performed only for the I-th required information assigned to two or more injection molding machines that have the same priority.

  (Step S304) The priority order calculating unit 14 calculates a priority order based on the total injection time calculated in step S303. Specifically, the priority is calculated so that the shorter the total injection time, the higher the priority. Here, the calculation of the priority order includes changing the priority order of the peers to that of the peers.

  Here, the principle of calculating the priority order will be briefly described. In the calculation of the priority order in step S206 in the flowchart of FIG. 3, a lot of necessary information for using the same mold is gathered in an efficient injection molding machine, that is, an injection molding machine capable of molding many molded products in a short time. The priority order is calculated. Therefore, some injection molding machines do not collect much necessary information. By calculating the priority order in step S304, the priority order can be calculated so that the required information is collected in an injection molding machine that does not collect such a large amount of required information. You can avoid concentrating on the machine.

  (Step S305) The priority order calculation unit 14 determines whether there is a peer for one or more priorities calculated for the I-th required information. If there is a peer priority, the process proceeds to step S306, and if not, the process proceeds to step S308.

  (Step S306) The priority calculation unit 14 calculates the total number of injections of required information using other molds for the I-th required information allocated to two or more injection molding machines. Here, the calculation will be described. The priority order calculation unit 14 first pays attention to the required information assigned to one injection molding machine by the required expansion unit 13 among the I-th required information. Next, the priority order calculation unit 14 is required information allocated to the same injection molding machine as the required information of interest among all the required information allocated to each injection molding machine by the required expansion unit 13. The total number of injections of the required information using a mold different from the required required information is calculated. It is assumed that the number of injections is the same as the required number as in the above description. The calculation of the total number of injections may or may not be performed only for the same priority among the I-th required information assigned to two or more injection molding machines.

  (Step S307) The priority order calculation unit 14 calculates a priority order based on the total number of injections calculated in step S306. Specifically, the priority order is calculated so that the smaller the total number of injections of required information using other molds, the higher the priority order. Here, the calculation of the priority order includes changing the priority order of the peers to that of the peers. The principle of calculating the priority order in step S307 is the same as that in step S304.

(Step S308) The priority calculation unit 14 determines whether or not the I-th required information is the last required information. If it is the last required information, the process ends. If not, the process proceeds to step S309.
(Step S309) The priority calculation unit 14 increments the counter I by “1”. Then, the process returns to step S302.

  Next, the operation of the information processing apparatus according to this embodiment will be described using a specific example. In this specific example, the information processing apparatus 10 is assumed to be a PC (Personal Computer) shown in FIG. First, it is assumed that the user operates the information processing apparatus 10 and inputs required information and tact time information to the required information storage unit 11 and the tact time information storage unit 12 of the information processing apparatus 10. Here, the required information stored in the required information storage unit 11 is assumed to be as shown in FIG. In the required information shown in FIG. 6, the required number, the molded product identification information, and the required number are associated with each other. The required number is information set for convenience in order to identify required information. In FIG. 6, each record is one piece of required information. The tact time information stored in the tact time information storage unit 12 is assumed to be as shown in FIG. In the tact time information shown in FIG. 7, mold identification information, molded product identification information, injection molding identification information, and tact time are associated with each other.

  Next, it is assumed that the user activates software for assigning required information, and the display shown in FIG. 5 is made on the display. In the display, when the user operates the mouse and clicks the “OK” button, a process of assigning required information is started.

  First, the required expansion unit 13 reads the required information from the required information storage unit 11 and reads the tact time information from the tact time information storage unit 12 (steps S101 and S102). Based on the required information and the tact time information, the required information is assigned to the assignable injection molding machine (step S103). Specifically, since the molded product identification information of the required information of the required number “001” is “N001”, it can be assigned to the sixth and seventh records of the tact time information shown in FIG. That is, the required information of the required number “001” is an injection molding machine identified by the injection molding identification information “equipment A” (hereinafter, this injection molding machine is referred to as an “injection molding machine“ equipment A ”, or simply“ equipment A ”). The same applies to other injection molding machines.) And the injection molding machine “equipment B”.

  FIG. 8 is a diagram showing a result of assigning necessary information in this way. The information shown in FIG. 8 will be called development information. In the development information, the priority “1” is associated with each record in advance. Here, it is assumed that a lower priority value has a higher priority. Further, in the development information, the ID is set for convenience in order to identify the record of the development information. Each record of the development information shown in FIG. 8 is the required information assigned to the injection molding machine that can be assigned by the required development unit 13. The required expansion unit 13 passes the expansion information to the priority order calculation unit 14. The priority order calculation unit 14 accumulates the development information in a recording medium (not shown).

  Next, the priority order calculation unit 14 calculates the priority order so that die switching is reduced and the overall efficiency is improved (step S104). Specifically, in the development information of FIG. 8, the first required information (required information whose required number is “001”) is assigned to two injection molding machines “equipment A” and “equipment B”. (Steps S201 and S202), the total number of injections is calculated for the two records whose development information IDs are “1” and “2” (step S203).

First, the priority order calculation unit 14 calculates the total number of injections for the record with ID “1”. In the record of ID “1”, the injection molding identification information is “facility A”, and the mold identification information is “mold C”. In the development information, records having the same injection molding identification information and mold identification information are records having IDs “1” and “19”. The priority calculation unit 14 calculates the number of injections of the records whose priority is not lower than the priority of the record with the ID “1” (that is, the peer record or the higher priority record). To calculate the total number of injections. In this case, since all the priorities are “1” and there is no record having a lower priority than the record with ID “1”, the priority calculation unit 14 records the records with ID “1” and “19”. A value “190” obtained by adding the required numbers of the two is calculated as the total number of injections of the record with ID “1”. Similarly, the priority order calculating unit 14 calculates the total number of injections “190” of the record with ID “2”.

  Since the total number of injections “190” of the record of ID “1” is the same as the total number of injections “190” of the record of ID “2” (step S204), each record of the required number “001” is recorded. The injection time is calculated (step S205). Specifically, the injection time of the record with ID “1” is “200 (seconds)” of the product of the required number “100” and the tact time “2”, and the injection time of the record with ID “2” is The product of the required number “100” and the tact time “3” is “300 (seconds)”.

  Next, the priority order calculation unit 14 calculates a priority order for the first income information (step S206). Specifically, since there is no difference in the total number of injections of the records with IDs “1” and “2”, the priority order of the longer injection time is changed from “1” to “2”. FIG. 9 shows development information indicating the priority order calculated in this way. In the development information of FIG. 9, the calculated total number of injections (total injection time) and the injection time are added as new fields. Further, the priority of the required number “001” is updated.

  Since the 1st required information is not the last required information (step S207), the priority calculation part 14 calculates a priority similarly about 2nd required information (step S208, S202-S206). FIG. 10 is a diagram showing the development information in which the priorities for all necessary information are calculated in this way.

  As shown in FIG. 11, the records surrounded by a thick frame, that is, the required information of the required numbers “003”, “004”, “006”, and “007” have the same priority (step S105). ). Therefore, the priority order calculation unit 14 calculates the priority order so that the required information is assigned to the injection molding machine with a small load (step S106).

  Specifically, the priority calculation unit 14 has third-order required information (required information whose required number is “003”) in the development information shown in FIG. is there. Therefore, no processing is performed on the first and second required information (steps S301, S302, S308, and S309). The priority calculation unit 14 calculates the total injection time for each record of the third required information (steps S302 and S303).

  First, the priority order calculation unit 14 calculates the total injection time for the record with ID “6”. In the record of ID “6”, the injection molding identification information is “facility A”, and the mold identification information is “mold B”. In the development information, records having the same injection molding identification information as the record of ID “6” and different mold identification information are ID “1”, “3”, “8”, “11”, “16”, “19”. The priority calculation unit 14 calculates the total injection time using the injection time of the records whose priority is not lower than the priority “1” of the record with ID “6” among these records. In this case, the priorities of the records with IDs “1”, “3”, “8”, “11”, “16”, “19” are all “1”, and the priority of the record with ID “6” Since there is no record lower than the ranking “1”, the priority ranking calculation unit 14 adds the injection times of the records with IDs “1”, “3”, “8”, “11”, “16”, “19”. The calculated value “2580” is calculated as the total injection time of the record with ID “6”. Since the injection time is not calculated for ID “19”, the priority calculation unit 14 calculates the total injection time after calculating the injection time.

  Next, the priority order calculation unit 14 calculates the total injection time for the record with ID “7”. In the record of ID “7”, the injection molding identification information is “equipment C”, and the mold identification information is “mold B”. In the development information, records having the same injection molding identification information as the record of ID “7” and different mold identification information are IDs “5”, “10”, “13”, and “18”. The priority calculation unit 14 calculates the total injection time using the injection times of the records whose priority is not lower than the priority “1” of the record with ID “7” among these records. In this case, among the records with IDs “5”, “10”, “13”, and “18”, the records with IDs “5” and “13” have a lower priority than the priority “1”. The total of the injection times of the record “7” is “400” obtained by adding the injection times of the records of ID “10” and “18”.

  As a result, the priority calculation unit 14 calculates “1” as the priority of the record with the short ID “7” of the total injection time, and sets “1” as the priority of the record with the long ID “6” of the total injection time. 2 "is calculated (step S304). FIG. 12 is a diagram illustrating the development information after the priority order is calculated for the third required information.

  Since the priority information for the third required information is not the same (step S305), the priority calculating unit 14 next calculates the total injection time for the fourth required information, and gives priority. The ranking is calculated in the same manner (steps S302 to S305). FIG. 13 is a diagram showing the development information including the priority order calculated as described above.

  The priority order calculation unit 14 reads the development information stored in a recording medium (not shown) and passes it to the required allocation unit 15. The required allocation unit 15 allocates required information by selecting a record having a priority “1” in the received development information. Specifically, in the development information shown in FIG. 13, for the required information with the required number “001”, the record with ID “1” having the priority “1” is selected. That is, the required information of the required number “001” is assigned to the injection molding machine “equipment A”. Similarly, the required information of the required number “002” is assigned to the injection molding machine “equipment A”. Thus, the required allocation part 15 allocates required information to any injection molding machine (step S107). Then, the required allocation unit 15 displays the allocation information shown in FIG. 14 on the display. As a result, the user who operates the information processing apparatus 10 can know what kind of assignment is performed.

  Here, what kind of required allocation is performed by the information processing apparatus 10 will be described. In the allocation information of FIG. 14, when the correspondence between each required number and the mold is clearly shown, it is as shown in FIG. In FIG. 15, in the facility A, molding by the mold A and molding by the mold C are performed. Further, in the facility B, molding by the mold D is performed. Further, in the facility C, molding by the mold B is performed. In this way, molding with the same mold is not performed across two or more injection molding machines, and efficient required allocation is performed. Further, with reference to the tact time information shown in FIG. 7, it is considered that the facility A can perform the molding most efficiently. It is thought that good molding can be performed.

In the above specific example, the processes in steps S306 and S307 in the flowchart of FIG. 4 were not performed. A specific example of the processes in steps S306 and S307 will be briefly described. Suppose that in the third required information, the priority of the record with ID “6” and the record with ID “7” is the same even if the total injection time is used. Then, as in the above description, the priority order calculation unit 14 is a record assigned to the same injection molding machine as the record with ID “6” for the record with ID “6”, and uses a different mold. The total “410” of the number of injections (required number) of the records with IDs “1”, “3”, “8”, “11”, “16”, and “19” is calculated. Even in this case, the addition is performed only for the record whose priority is lower than the priority “1” of the record with ID “6”. On the other hand, the record with ID “7” is the record assigned to the same injection molding machine as the record with ID “7”, and the record using ID “5” is the same as described above. , “10”, “13”, “18” records having a priority order lower than the priority order “1” of the record with ID “7”, that is, records with ID “10”, “18” The total number of injections (required number) of “40” is calculated. Therefore, the priority calculation unit 14 calculates a higher priority for the record with ID “7” than the record with ID “6”.

  In the specific example, when calculating the total injection time (step S303) or calculating the total number of injections (step S203 or step S306), the priority order is higher than the required information of interest. Although the case where the injection time of the required information that is not low is used for the calculation has been described, this is an example, and may not be.

  In the above specific example, even when the processing of step S307 is completed, the required information assigned to the plurality of injection molding machines has the same priority and uniquely identifies the highest priority. If it is not possible, the required allocation unit 15 may determine which method of allocation of the required information to which injection molding machine. For example, the required allocation unit 15 randomly selects one of the required information allocated to a plurality of injection molding machines from the highest priority, and determines the allocation so that the selected allocation is performed. Alternatively, one having the highest priority may be selected according to a predetermined rule. The predetermined rule is, for example, “select in order of equipment A, equipment B, equipment C”, and the like.

  Further, in the above specific example, the priority “1” is associated with all the required information at the time of assignment by the required expansion unit 13, but this need not be the case. For example, at the time of allocation by the required expansion unit 13, the lowest priority ("3" in the above specific example) is associated with all the required information, and the priority calculation unit 14 calculates the priority to make it higher. The priority order may be updated to be the priority order.

  As described above, according to the information processing apparatus 10 according to the present embodiment, when allocating required information to any of a plurality of injection molding machines, it is possible to execute allocation so that molding can be performed more efficiently. Appropriate molding can be performed.

  In the present embodiment, the processing in step S307 in FIG. 4, that is, one required information assigned to two or more injection molding machines by the required developing unit 13 is one in the priority order. The required information assigned to the same injection molding machine as the required information assigned to the injection molding machine, and the required information using the mold different from the required information assigned to the one injection molding machine The total is calculated for each required information having the same priority assigned to two or more injection molding machines by the required developing unit 13, and the priority is set so that the smaller the total number of injections, the higher the priority. Although the case where the calculation process is executed has been described, this process is not an essential process and may not be executed.

Further, in the present embodiment, the processing in step S303 in FIG. 4, that is, when one required information assigned to two or more injection molding machines by the required developing unit 13 is the same in priority order, The required information assigned to the same injection molding machine as the required information assigned to the injection molding machine, and the injection time of the required information using a mold different from the required information assigned to the one injection molding machine. The total is calculated for each piece of required information having the same priority assigned to two or more injection molding machines by the required developing unit 13, and the priority is set so that the shorter the total injection time, the higher the priority. Although the case where the calculation process is executed has been described, this process is not an essential process and may not be executed.

  In the present embodiment, the process of step S203 in FIG. 3, that is, the required information assigned to the same injection molding machine as the required information assigned to one injection molding machine, The required number of injections of the required information using the same mold as the required information assigned to the machine is calculated for the required information assigned to two or more injection molding machines by the required development unit 13, and the total number of injections is calculated. Although the case where the process of calculating the priority order is executed so that the higher the priority order is has been described, this process is not an essential process and may not be executed.

  In the present embodiment, the case where the jig is a mold has been described. However, as described above, the jig may not be a mold, and even in this case, the same as in the present embodiment. The effect of can be produced.

  In the present embodiment, the case where the required allocation unit 15 allocates the required information and outputs the result based on the priority calculated by the priority calculation unit 14 has been described. However, the priority calculation unit 14 Information indicating the result of the priority order calculated by may be output. For example, as in the information processing apparatus 20 shown in FIG. 16, the required information storage unit 11, the tact time information storage unit 12, the required expansion unit 13, the priority calculation unit 14, and the output unit 21 are provided. It may be. Here, the configuration and operation other than the output unit 21 are the same as described above. The output unit 21 is the same as the output unit 16 except that priority order information is output instead of the allocation information. The priority order information is information indicating the result calculated by the priority order calculation unit 14. For example, as shown in FIG. 17, the priority order information is information that associates a required number, injection molding identification information, and priority order.

  Moreover, although the case where the information processing apparatus 10 is a stand-alone was demonstrated in the said specific example, the information processing apparatuses 10 and 20 may be a stand-alone and may be a server of a server client system. For example, as illustrated in FIG. 18, the information processing apparatus 10 and a plurality of client terminals are connected to the communication line 100, and the information processing apparatus 10 calculates priority in response to a request from the client terminal. The required information may be assigned and the result may be transmitted to the client terminal. In this case, the output units 16 and 21 transmit allocation information and priority order information to the client terminal. The communication line 100 is, for example, the Internet, an intranet, a public telephone line network, or the like.

  Further, in the present embodiment, the priority order may be calculated in consideration of the date. For example, if the required information shown in FIG. 6 is for performing injection molding on June 10, 2005, the allocation of the required information on June 9, 2005 is fixed as shown in FIG. Suppose. In that case, taking into account the allocation of the required information shown in FIG. 19, the calculation of the priority for the required information shown in FIG. 6 and the final allocation of the required information based on the priority are performed. Also good. For example, in the calculation of the total number of injections in step S203, the calculation may be performed in consideration of the number of injections of information shown in FIG. The same applies to the calculations in steps S303 and S306.

In the above embodiment, each component may be configured by dedicated hardware, or a component that can be realized by software may be configured by software under program control. When configured by software, for example, each component can be realized by a program execution unit such as a CPU reading and executing a software program recorded on a recording medium such as a hard disk or a semiconductor memory.
