The power consumption collection device 10 can comprise a processing unit 32, a storage unit 34, an operating unit 36, a display unit 38, and a communication unit 40. The power consumption collection device 10 can also include other components in addition to these, the description of which is omitted here. A program that causes a computer to execute the power consumption monitoring procedure according to the present embodiment can be pre-installed in the storage unit 34. Specifically, application software for power consumption monitoring can be pre-installed in the power consumption monitoring device 10. The application software for power consumption monitoring can, for example, be downloaded to the power consumption monitoring device 10 via a website, but this is not the only option. The computing unit 32 is configured by a processor, such as a CPU or a GPU. That is, the computing unit 32 is configured by a processing circuit. The computing unit 32 comprises an information acquisition unit 42, a receiving unit 44, a receiving unit 46 for order type information, a destination unit 48, a power consumption collection unit 50, and a display control unit 52. The information acquisition unit 42, the receiving unit 44, the receiving unit 46 for order type information, the destination unit 48, the power consumption collection unit 50, and the display control unit 52 can be implemented by the computing unit 32 executing a program stored in the memory unit 34.At least part of the information acquisition unit 42, the receiving unit 44, the receiving unit 46 for order type information, the destination unit 48, the power consumption collection unit 50, and the display control unit 52 can be implemented by an integrated circuit, such as an ASIC or an FPGA.

At least one portion of the memory unit 34 may, as described above, be encompassed by the processor, the integrated circuit, or the like. The information acquisition unit 42 obtains information indicating the power consumption of the injection molding cell 12. The information acquisition unit 42 obtains measurement data from the injection molding cell 12. The receiving unit 44 receives information indicating the machine status of the injection molding cell 12. The receiving unit 46 for job type information receives information indicating a job type specified by the user. The determination unit 48 determines whether the molded part produced in the injection molding cell 12 is acceptable or not. The power consumption collection unit 50 collects the power consumption according to a collection rule. The display control unit 52 causes at least one of the display units 26 and 38 to display information indicating the collection result of the power consumption collection unit 50. Fig. 3 shows a flowchart describing an example of a power consumption collection method according to the embodiment. In step S1, the user selects one of the first to eighth collective rules. Specifically, the user selects a collective rule, for example, by actuating the control unit 36 ​​of the power consumption collective device 10. The user can select the collective rule by actuating the control unit 24 of a single injection molding cell 12 among a multitude of injection molding cells 12. In this case, information specifying the selected collective rule is transmitted from the injection molding cell 12 to the power consumption collective device 10 via the network 14. The number of collective rules that the user can select can be one or more (different from eight). (First collection rule) As shown in Fig. 4A, according to the first collection rule, the power consumption is collected for each of a plurality of machine states encompassed in each of the injection molding cells 12. The plurality of machine states is determined in advance and stored in the storage unit 34. The plurality of machine states includes, for example, an injection molding state, an emergency stop state, an anomalous stop state, and a manual state. The injection molding state refers to a state in which the injection molding machine 16 is injection molding a part. The emergency stop state refers to a state in which the injection molding machine 16 is stopped by pressing an emergency stop switch (emergency stop button) (not shown). The anomalous stop state refers to a state in which the injection molding cell 12 is stopped due to an anomaly. In other words, the anomalous stop state refers to a state in which the injection molding machine 16 is stopped, for example, due to an alarm triggered by the injection molding cell 12. The anomalous stop state excludes a stop state caused by pressing the emergency stop switch. The manual state refers to a state in which the injection molding machine 16 is stopped that is neither the emergency stop state nor the anomalous stop state. In the manual state, the injection molding machine 16 can be operated manually.The machine states stored in memory unit 34 can be adjusted accordingly. If the user selects the first collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the first collection rule. In this case, the process proceeds to step S2a in Fig. 4B. In step S2a, the receiving unit 44 receives information indicating one or more of the machine states to be used for the power consumption monitoring of each injection molding cell 12. Specifically, the receiving unit 44 receives this information, for example, when the user operates the control unit 36 ​​of the power consumption monitoring device 10 or the control unit 24 of one of the injection molding cells 12 to indicate one or more of the machine states. The process then proceeds to step S2b. In step S2b, the information acquisition unit 42 obtains information indicating the power consumption of each injection molding cell 12. Specifically, in each injection molding cell 12, the power sensor 30 sequentially measures the power consumption of the injection molding machine 16, and the power sensor 31 sequentially measures the power consumption of the peripheral device 18.Information indicating the power consumption measured by power sensors 30 and 31 is transmitted from each injection molding cell 12 to the power consumption collection device 10 via network 14. Accordingly, the information acquisition unit 42 can obtain information indicating the power consumption of each injection molding cell 12. The power consumption information obtained by the information acquisition unit 42 in step S2b is combined with the information received in step S2a, which indicates one or more of the machine states. Therefore, the power consumption for each of the multiple machine states can be determined from the information obtained by the information acquisition unit 42. The process then proceeds to step S3. In step S3, the unit of determination 48 determines whether the condition for energy consumption collection is met or not. The condition for energy consumption collection is defined in advance and can, for example, include collection at fixed time intervals, collection at set times, or similar. The condition for energy consumption collection can be set accordingly. If the unit of determination 48 determines that the condition for energy consumption collection is not met (NO in step S3), the process proceeds to step S2a. If the unit of determination 48 determines that the condition for energy consumption collection is met (YES in step S3), the process proceeds to step S4. In step S4, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or a calculated value of the power consumption) for each of the plurality of machine states in each of the injection molding cells 12. The calculated value of the power consumption includes, for example, a maximum value, a minimum value, an average value, a standard deviation, and the like. In the present embodiment, the power consumption collection unit 50 collects the power consumption of each injection molding cell 12 separately for each of the injection molding states: the emergency stop state, the anomalous stop state, and the manual state.Specifically, the power consumption collection unit 50 performs the following tasks, for example: collecting the power consumption in the injection molding state for each injection molding cell 12, collecting the power consumption in the emergency stop state for each injection molding cell 12, collecting the power consumption in the anomalous stop state for each injection molding cell 12, and collecting the power consumption in the manual state for each injection molding cell 12. Furthermore, the power consumption collection unit 50 can also collect the average power consumption in the injection molding state for each injection molding cell 12, the average power consumption in the emergency stop state for each injection molding cell 12, the average power consumption in the anomalous stop state for each injection molding cell 12, and the average power consumption in the manual state for each injection molding cell 12.This makes it possible to record the power consumption of each injection molding cell 12 separately for each of the multitude of machine states. In step S4, the power consumption collection unit 50 can also separately collect the total power consumption in the injection molding state, the total power consumption in the emergency stop state, the total power consumption in the anomalous stop state and the total power consumption in the manual state. The total power consumption in the injection molding state is obtained by summing the power consumption of each injection molding cell 12 in the injection molding state. The total power consumption in the emergency stop state is obtained by summing the power consumption of each injection molding cell 12 in the emergency stop state. The total power consumption in the anomalous stop state is obtained by summing the power consumption of each injection molding cell 12 in the anomalous stop state. The total power consumption in the manual state is obtained by summing the power consumption of each injection molding cell 12 in the manual state. The power consumption collection unit 50 can calculate a value (which includes an average value, a maximum value, a minimum value, a standard deviation, and the like) for each of the total power consumptions described above. The process then proceeds to step S31 in Fig. 3. (Second collection rule) As shown in Fig. 5A, according to the second grouping rule, the multitude of machine states encompassed in each injection molding cell 12 are classified into a multitude of groups, and the power consumption is collected for each group. The multitude of machine states of the injection molding cell 12 is pre-classified into a multitude of groups. One or more machine states belong to a first group within the multitude of groups. A multitude of machine states that differ from those belonging to the first group belong to a second group within the multitude of groups. In the present embodiment, the plurality of collection groups includes, for example, the first collection group and the second collection group. The plurality of machine states includes, for example, an injection molding state, an emergency stop state, an anomalous stop state, and a manual state. The injection molding state belongs to the first collection group. The emergency stop state, the anomalous stop state, and the manual state belong to the second collection group. The classification of machine states into the first and second collection groups can be set accordingly. In the second collection rule, a large number of machine states can be classified into three or more collection groups. If the user selects the second collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the second collection rule. In this case, the process proceeds to step S5a in Fig. 5B. In step S5a, the receiving unit 44 receives information indicating one or more of the machine states intended for power consumption collection, each machine state belonging to one of the plurality of collection groups. Specifically, the receiving unit 44 receives the information, for example, when the user operates the control unit 36 ​​of the power consumption collection device 10 or the control unit 24 of one of the injection molding cells 12 to indicate one or more of the machine states belonging to each of the plurality of collection groups. The process then proceeds to step S5b. In step S5b, the information acquisition unit 42 obtains information indicating the power consumption of the collection groups of each injection molding cell 12.The information obtained by the information acquisition unit 42 in step S5b, which specifies the power consumption, is associated with the information received in step S5a, which specifies one or more of the machine states. Accordingly, the power consumption of each of the multiple collection groups can be determined from the information obtained by the information acquisition unit 42. The process then proceeds to step S6. In step S6, the unit of determination 48 determines whether the condition for the power consumption collection is met or not. If the unit of determination 48 determines that the condition for the power consumption collection is not met (NO in step S6), the process proceeds to step S5a. If the unit of determination 48 determines that the condition for the power consumption collection is met (YES in step S6), the process proceeds to step S7. In step S7, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or the calculated value of the power consumption) for each of the plurality of collection groups in each of the injection molding cells 12. In the present embodiment, the power consumption collection unit 50 collects the power consumption of each injection molding cell 12 separately for the first collection group and the second collection group. Specifically, the power consumption collection unit 50 collects, for example, the amount of power consumption of the first collection group of each injection molding cell 12 and the amount of power consumption of the second collection group of each injection molding cell 12. The power consumption collection unit 50 can collect the average value of the power consumption of the first collection group of each injection molding cell 12 and the average value of the power consumption of the second collection group of each injection molding cell 12.Accordingly, the power consumption of each injection molding cell 12 can be recorded separately for each of the numerous collection groups. In step S7, the power consumption collection unit 50 can collect the total power consumption obtained by summing the power consumption of the first collection group of each injection molding cell 12, and likewise the total power consumption obtained by summing the power consumption of the second collection group of each injection molding cell 12. The power consumption collection unit 50 can calculate the value of each total power consumption. The process then proceeds to step S31 in Fig. 3. (Third collection rule) As shown in Fig. 6A, according to the third collection rule, the user designates one or more of the machine states belonging to a plurality of collection groups, and the power consumption is collected for each of the plurality of collection groups. In the present embodiment, the plurality of collection groups includes, for example, a first collection group and a second collection group. The number of collection groups can be three or more. If the user selects the third collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the third collection rule. In this case, the process proceeds to step S8 in Fig. 6B. In step S8, the receiving unit 44 receives information indicating one or more of the machine states that are intended for power consumption collection, each machine state belonging to one of the plurality of collection groups. Specifically, the receiving unit 44 receives the information, for example, when the user operates the control unit 36 ​​of the power consumption collection device 10 or the control unit 24 of one of the injection molding cells 12 to indicate one or more of the machine states belonging to each of the plurality of collection groups. In the present embodiment, the injection molding state and the manual state are identified as the machine states belonging to the first group. Furthermore, the emergency stop state and the abnormal stop state are identified as the machine states belonging to the second group. The process then proceeds to step S9. In step S9, the information acquisition unit 42 obtains information indicating the power consumption of each injection molding cell 12. The power consumption information obtained by the information acquisition unit 42 in step S9 is combined with the information received in step S8, which indicates one or more of the machine states. Accordingly, the power consumption of each of the multiple assembly groups can be determined from the information obtained by the information acquisition unit 42. The process then proceeds to step S10. In step S10, the unit of determination 48 determines whether the condition for the power consumption collection is met or not. If the unit of determination 48 determines that the condition for the power consumption collection is not met (NO in step S10), the process proceeds to step S8. If the unit of determination 48 determines that the condition for the power consumption collection is met (YES in step S10), the process proceeds to step S11. In step S11, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or the calculated value of the power consumption) for each of the plurality of collection groups in each of the injection molding cells 12. In the present embodiment, the power consumption collection unit 50 collects the power consumption of each injection molding cell 12 separately for the first collection group and the second collection group. Accordingly, the power consumption of each injection molding cell 12 can be recorded separately for each of the plurality of collection groups. Since the user can also indicate which machine state belongs to which collection group, the power consumption of each injection molding cell 12 can easily be recorded separately for any desired item. In step S11, the power consumption collection unit 50 can collect the total power consumption obtained by summing the power consumption of the first collection group of each injection molding cell 12, and likewise the total power consumption obtained by summing the power consumption of the second collection group of each injection molding cell 12. The power consumption collection unit 50 can calculate the value of each total power consumption. The process then proceeds to step S31 in Fig. 3. (Fourth collection rule) As shown in Fig. 7A, according to the fourth collection rule, the power input required for injection molding of defect-free products (acceptable products) and the power input required for injection molding of defective products (unacceptable products) are collected separately. If the user selects the fourth collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the fourth collection rule. In this case, the process proceeds to step S12a in Fig. 7B. In step S12a, the information acquisition unit 42 obtains measurement data from each of the injection molding cells 12. This measurement data includes, for example, the injection molding time required to mold a single part. The measurement data is not limited to injection molding time and can include mold temperature, mold clamping force, and the like. After the injection molding of a part is complete, the process proceeds to step S12b. In step S12b, the determination unit 48 determines whether the part is acceptable or not. Each time a part is injection molded (i.e., at each cycle), the determination unit 48 determines whether the part is acceptable or not. The determination unit 48 uses the measurement data from the injection molding cell 12 during the injection molding process to determine whether the part is acceptable or not.If the measurement data is the injection molding time required to mold a part, the unit of determination 48 determines, for example, that the part is acceptable if the injection molding time is within a predetermined permissible time range, and determines that the part is not acceptable if the injection molding time is outside the permissible time range. If unit of determination 48 determines that the molded part is acceptable, the process proceeds to step S13. If unit of determination 48 determines that the molded part is not acceptable, the process proceeds to step S14. In step S13, the information acquisition unit 42 obtains information indicating the power input (the amount of power consumed) required to injection mold the part deemed acceptable. The power input required to injection mold the acceptable part can subsequently be referred to as "power input during injection molding of the acceptable product." The process then proceeds to step S15. In step S14, the information acquisition unit 42 obtains information indicating the power input (the amount of power consumed) required to injection mold the part deemed unacceptable. This power input can subsequently be referred to as "power consumption during injection molding of the unacceptable product." The process then proceeds to step S15. In step S15, the unit of determination 48 determines whether the condition for the power consumption collection is met or not. If the unit of determination 48 determines that the condition for the power consumption collection is not met (NO in step S15), the process proceeds to step S12a. If the unit of determination 48 determines that the condition for the power consumption collection is met (YES in step S15), the process proceeds to step S16. In step S16, the power consumption collection unit 50 collects the power consumption during the injection molding of the acceptable part as well as the power consumption during the injection molding of the non-acceptable part in each injection molding cell 12. Accordingly, the power consumption of each injection molding cell 12 can be recorded separately for the case in which the part is determined to be acceptable and for the case in which the part is determined to be non-acceptable. In step S16, the power consumption collection unit 50 can collect the total power consumption obtained by summing the power consumption during injection molding of the acceptable part in each of the injection molding cells 12, and separately collect the total power consumption obtained by summing the power consumption during injection molding of the unacceptable part in each of the injection molding cells 12. The power consumption collection unit 50 can calculate the value of each total power consumption. The process then proceeds to step S31 in Fig. 3. (Fifth rule of collecting) As shown in Fig. 8A, the power consumption for each of a plurality of time slots is collected according to the fifth collection rule. In the present embodiment, the plurality of time slots comprises a first time slot (from 8:00 to 10:00), a second time slot (from 10:00 to 13:00), a third time slot (from 13:00 to 15:00), and a fourth time slot (from 15:00 to 17:00). The plurality of time slots can be set accordingly. If the user selects the fifth collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the fifth collection rule. In this case, the process proceeds to step S17a in Fig. 8B. In step S17a, the receiving unit 44 receives information specifying a plurality of time slots (for example, the first to fourth time slots) designated for power consumption collection. Specifically, the user operates the control unit 36 ​​of the power consumption collection device 10 or the control unit 24 of one of the injection molding cells 12 to designate a plurality of time slots, and the receiving unit 44 receives this information. The process then proceeds to step S17b. In step S17b, the information acquisition unit 42 obtains information specifying the power consumption of each injection molding cell 12. The power consumption information obtained by the information acquisition unit 42 in step S17b is combined with the information received in step S17a specifying the plurality of time slots.Therefore, the power consumption for each of the multiple time slots can be determined from the information obtained by the information acquisition unit 42. The process then proceeds to step S18. In step S18, the unit of determination 48 determines whether the condition for the power consumption collection is met or not. If the unit of determination 48 determines that the condition for the power consumption collection is not met (NO in step S18), the process proceeds to step S17a. If the unit of determination 48 determines that the condition for the power consumption collection is met (YES in step S18), the process proceeds to step S19. In step S19, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or the calculated value) for each of the plurality of time slots in each of the injection molding cells 12. In the present embodiment, the power consumption collection unit 50 collects the power consumption for each injection molding cell 12 separately for each of the first, second, third, and fourth time slots. Specifically, the power consumption collection unit 50 collects, for example, the amount of power consumption in the first time slot for each injection molding cell 12, the amount of power consumption in the second time slot for each injection molding cell 12, the amount of power consumption in the third time slot for each injection molding cell 12, and the amount of power consumption in the fourth time slot for each injection molding cell 12.The power consumption collection unit 50 can collect the calculated power consumption value in the first time slot for each injection molding cell 12, the calculated power consumption value in the second time slot for each injection molding cell 12, the calculated power consumption value in the third time slot for each injection molding cell 12, and the calculated power consumption value in the fourth time slot for each injection molding cell 12. Accordingly, the power consumption for each injection molding cell 12 can be recorded separately for each of the multiple time slots. In step S19, the power consumption collection device 10 can separately collect the total power consumption obtained by summing the power consumption in the first time slot of each of the injection molding cells 12, the total power consumption obtained by summing the power consumption in the second time slot of each of the injection molding cells 12, the total power consumption obtained by summing the power consumption in the third time slot of each of the injection molding cells 12, and the total power consumption obtained by summing the power consumption in the fourth time slot of each of the injection molding cells 12.

(Sixth Collection Rule) As shown in Fig. 9A, according to the sixth collection rule, the power consumption for each of a plurality of work shifts (work time slots) of an operator who operates the plurality of injection molding cells 12 is collected. In the present embodiment, the plurality of work shifts comprises a first work shift (from 8:00 to 16:00), a second work shift (from 16:00 to 24:00), and a third work shift (from 0:00 to 8:00). The plurality of work shifts (work time slots) can be set accordingly. If the user selects the sixth collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the sixth collection rule. In this case, the process proceeds to step S20a in Fig. 9B. In step S20a, the receiving unit 44 receives information specifying a number of work shifts (for example, the first to third work shifts) intended for power consumption collection. Specifically, the user operates the control unit 36 ​​of the power consumption collection device 10 or the control unit 24 of one of the injection molding cells 12 to indicate a number of work shifts, and the receiving unit 44 receives this information. The process then proceeds to step S20b. In step S20b, the information acquisition unit 42 obtains information specifying the power consumption of each injection molding cell 12. The power consumption information obtained by the information acquisition unit 42 in step S20b is combined with the information received in step S20a specifying the number of work shifts.Therefore, the power consumption for each of the numerous work shifts can be determined from the information obtained by information acquisition unit 42. The process then proceeds to step S21. In step S21, the unit of determination 48 determines whether the condition for the power consumption collection is met or not. If the unit of determination 48 determines that the condition for the power consumption collection is not met (NO in step S21), the process proceeds to step S20a. If the unit of determination 48 determines that the condition for the power consumption collection is met (YES in step S21), the process proceeds to step S22. In step S22, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or the calculated value) for each of the operator's multiple work shifts in each of the injection molding cells 12. In the present embodiment, the power consumption collection unit 50 collects the power consumption for each injection molding cell 12 separately for the first work shift, the second work shift, and the third work shift. Specifically, the power consumption collection unit 50 collects, for example, the amount of power consumption in the first work shift for each injection molding cell 12, the amount of power consumption in the second work shift for each injection molding cell 12, and the power consumption in the third work shift for each injection molding cell 12.The power consumption collection unit 50 can collect the calculated power consumption value for the first work shift for each injection molding cell 12, the calculated power consumption value for the second work shift for each injection molding cell 12, and the calculated power consumption value for the third work shift for each injection molding cell 12.

(Seventh collection rule) As shown in Fig. 10A, in the seventh collection rule the power consumption is collected for each of a large number of job types specified by the user. If the user selects the seventh collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the seventh collection rule. In this case, the process proceeds to step S23 in Fig. 10B. In step S23, a receiving unit 46 for job type information receives information specifying a variety of job types intended for power consumption collection. Specifically, the user operates the control unit 36 ​​of the power consumption collection device 10 or the control unit 24 of one of the injection molding cells 12 to designate a variety of job types, and the receiving unit 46 for job type information receives the corresponding information. In this embodiment, a variety of job types are designated as mass production operation, trial production operation, setup operation, and machine setup operation. The receiving unit 46 for order type information can receive a variety of order types by having the user operate the control unit 36 ​​of the power consumption collection device 10 to enter an order type code. The order type code is a type code used to identify the content of the order type. The order type codes are predetermined and stored in the memory unit 34. The order type codes can be set by the user as needed. In this way, it is possible to easily enter a frequently used order type by using the order type codes. The process then proceeds to step S24. In step S24, the information acquisition unit 42 obtains information specifying the power consumption of each injection molding cell 12. The power consumption information obtained by the information acquisition unit 42 in step S24 is then combined with the information received in step S23, which specifies the variety of order types. Therefore, the power consumption for each of the variety of order types can be determined from the information obtained by the information acquisition unit 42. The process then proceeds to step S25. In step S25, the unit of determination 48 determines whether the condition for power consumption collection is met or not. If the unit of determination 48 determines that the condition for power consumption collection is not met (NO in step S25), the process proceeds to step S23. If the unit of determination 48 determines that the condition for power consumption collection is met (YES in step S25), the process proceeds to step S26. In step S26, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or the calculated value) for each of the plurality of order types in each of the injection molding cells 12. In the present embodiment, the power consumption collection unit 50 collects the power consumption for each injection molding cell 12 separately for the mass production operation, the trial production operation, the setup operation, and the machine setting operation. Specifically, the power consumption collection unit 50 collects, for example, the amount of power consumption for the mass production operation for each injection molding cell 12, the amount of power consumption for the trial production operation for each injection molding cell 12, the amount of power consumption for the setup operation for each injection molding cell 12, and the amount of power consumption for the machine setting operation for each injection molding cell 12.The power consumption collection unit 50 can collect the calculated power consumption of each injection molding cell 12 during mass production operation, the calculated power consumption of each injection molding cell 12 during trial production operation, the calculated power consumption of each injection molding cell 12 during setup operation, and the calculated power consumption of each injection molding cell 12 during machine adjustment operation. Accordingly, the power consumption of each injection molding cell 12 can be recorded separately for each of a variety of order types. In step S26, the power consumption collection unit 50 can separately collect the total power consumption obtained by summing the power consumption of each of the injection molding cells 12 during mass production operation, the total power consumption obtained by summing the power consumption of each of the injection molding cells 12 during trial production operation, the total power consumption obtained by summing the power consumption of each of the injection molding cells 12 during setup operation, and the total power consumption obtained by summing the power consumption of each of the injection molding cells 12 during machine setup operation. The power consumption collection unit 50 can calculate the value of each total power consumption. The process then proceeds to step S31 in Fig. 3. (Eighth rule of collecting) As shown in Fig. 11A, according to the eighth collection rule, the user designates one or more job types, each belonging to a plurality of job type collection groups, and the power consumption is collected for each of the plurality of job type collection groups. The plurality of job type collection groups includes, for example, a first job type collection group, a second job type collection group, and a third job type collection group. The number of job type collection groups can be two, four, or more. If the user selects the eighth collection rule in step S1, the power consumption of the multiple injection molding cells 12 is collected according to the eighth collection rule. In this case, the process proceeds to step S27 in Fig. 11B. In step S27, the order type information receiving unit 46 receives information specifying one or more of the order types belonging to each of the plurality of order type collection groups provided for power consumption collection. Specifically, the user operates the control unit 36 ​​of the power consumption collection device 10 or the control unit 24 of one of the injection molding cells 12 to designate one or more of the order types belonging to each of the plurality of order type collection groups, and the order type information receiving unit 46 receives the corresponding information. In the present embodiment, the mass production operation is designated as the order type belonging to the first order type collection group. Furthermore, the trial production operation is designated as the order type belonging to the second order type collection group.Furthermore, the setup operation and the machine adjustment operation are identified as the order types belonging to the third order type group. The process then proceeds to step S28. In step S28, the information acquisition unit 42 obtains information specifying the power consumption of each injection molding cell 12. The power consumption information obtained by the information acquisition unit 42 in step S28 is associated with the information specifying one or more of the order types received in step S27. Therefore, the power consumption for each of the multiple order type collection groups can be determined from the information obtained by the information acquisition unit 42. The process then proceeds to step S29. In step S29, the unit of determination 48 determines whether the condition for power consumption collection is met or not. If the unit of determination 48 determines that the condition for power consumption collection is not met (NO in step S29), the process proceeds to step S27. If the unit of determination 48 determines that the condition for power consumption collection is met (YES in step S29), the process proceeds to step S30. In step S30, the power consumption collection unit 50 collects the power consumption (the amount of power consumption or the calculated value) for each of the plurality of job type collection groups in each of the injection molding cells 12. In the present embodiment, the power consumption collection unit 50 collects the power consumption for each injection molding cell 12 separately for each of the first job type collection group, the second job type collection group, and the third job type collection group. Specifically, the power consumption collection unit 50 collects, for example, the amount of power consumption of the first job type collection group for each injection molding cell 12, the amount of power consumption of the second job type collection group for each injection molding cell 12, and the amount of power consumption of the third job type collection group for each injection molding cell 12.The power consumption collection unit 50 can collect the calculated power consumption value of the first job type collection group for each injection molding cell 12, the calculated power consumption value of the second job type collection group for each injection molding cell 12, and the calculated power consumption value of the third job type collection group for each injection molding cell 12. Accordingly, the power consumption of each injection molding cell 12 can be recorded separately for each of the multiple job type collection groups. In step S30, the power consumption collection unit 50 can separately collect the total power consumption obtained by summing the power consumption of the first job type collection group of each injection molding cell 12, the total power consumption obtained by summing the power consumption of the second job type collection group of each injection molding cell 12, and the total power consumption obtained by summing the power consumption of the third job type collection group of each injection molding cell 12.

In step S31, the display control unit 52 shows the total result on at least one of the display units 26 and 38. This allows the user to easily grasp the total result. The display control unit 52 can display the result on either the display unit 26 or the display unit 38 in the form of a table or a chart. The process shown in Fig. 3 is then complete.
