More specifically, power tallying application software may be pre-installed in the power tallying device 10. The power tallying application software may be downloaded to the power tallying device 10 via, for example, a website or the like, but is not limited to this.

[0024] The calculation unit 32 is configured by a processor such as a CPU or GPU. That is, the calculation unit 32 is configured by a processing circuit. The calculation unit 32 has an information acquisition unit 42, a reception unit 44, a job type information reception unit 46, a determination unit 48, a power tallying unit 50, and a display control unit 52.

The display control unit 52 displays information indicating the tallying results of the power tally unit 50 on at least one of the display unit 26 and the display unit 38.

[0027] FIG. 3 is a flowchart showing an example of a power calculation method according to this embodiment.

[0028] In step S1, the user selects one of the first to eighth tallying rules. Specifically, the user selects the tallying rule by, for example, operating the operation unit 36 ​​of the power tallying device 10. The user can select the tallying rule by operating the operation unit 24 of one of the multiple molding cells 12. In this case, information indicating the selected tallying rule is transmitted from the molding cell 12 to the power tallying device 10 via the network 14. The user can select one or more tallying rules (other than eight).

[0029] 4A, the first counting rule counts the power consumption for each of a plurality of machine states of each molding cell 12. The plurality of machine states are determined in advance and stored in the storage unit 34. The plurality of machine states include, for example, a molding state, an emergency stop state, an abnormal stop state, and a manual state.

[0030] The molding state refers to a state in which the injection molding machine 16 is molding a molded product. The emergency stop state refers to a state in which the injection molding machine 16 is stopped due to the operation of an emergency stop switch (emergency stop button) not shown. The abnormal stop state refers to a state in which the molding cell 12 is stopped due to an abnormality. In other words, the abnormal stop state refers to a state in which the injection molding machine 16 is stopped, for example, because the molding cell 12 has issued an alarm. Note that the abnormal stop state does not include a stop due to the operation of an emergency stop switch. The manual state refers to a state in which the injection molding machine 16 is stopped, neither due to an emergency stop state nor an abnormal stop state. In the manual state, the injection molding machine 16 can be operated manually. The machine states stored in the memory unit 34 can be set as appropriate.

[0031] If the user selects the first counting rule in step S1, the power consumption of the multiple molding cells 12 is counted according to the first counting rule. In this case, the process proceeds to step S2a in FIG. 4B.

[0032] In step S2a, the receiving unit 44 receives information indicating the machine status of each molding cell 12 for which the power consumption of that molding cell 12 is to be totaled. Specifically, for example, the user operates the operation unit 36 ​​of the power totalization device 10 or the operation unit 24 of any one of the molding cells 12 to specify the machine status, and the receiving unit 44 receives the information. Then, the process proceeds to step S2b. In step S2b, the information acquiring unit 42 acquires information indicating the power consumption of each molding cell 12. Specifically, in each 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 the power sensor 30 and the power sensor 31 is transmitted from each molding cell 12 to the power totalization device 10 via the network 14. This allows the information acquiring unit 42 to acquire information indicating the power consumption of each molding cell 12. The information indicating the power consumption acquired by the information acquiring unit 42 in step S2b is associated with the information indicating the machine status received in step S2a. Therefore, it is possible to obtain the power consumption for each of a plurality of machine states from the information acquired by the information acquisition unit 42. After that, the process proceeds to step S3.

[0033] In step S3, the determination unit 48 determines whether or not the conditions for power tallying are met. The conditions for power tallying are determined in advance, such as tallying at regular time intervals or at a specified time. The conditions for power tallying can be set as appropriate. If the determination unit 48 determines that the conditions for power tallying are not met (NO in step S3), the process proceeds to step S2a. If the determination unit 48 determines that the conditions for power tallying are met (YES in step S3), the process proceeds to step S4.

[0034] In step S4, the power tallying unit 50 tally the power consumption (power consumption amount or calculated power consumption value) for each molding cell 12 for each of multiple machine states. The calculated power consumption value includes, for example, the maximum, minimum, average, and standard deviation of power consumption. In this embodiment, the power tallying unit 50 tally the power consumption of each molding cell 12 for each of the molding state, emergency stop state, abnormal stop state, and manual state. Specifically, the power tallying unit 50 tally, for example, the power consumption of each molding cell 12 for each of the molding state, the power consumption of each molding cell 12 for each of the emergency stop state, the power consumption of each molding cell 12 for each of the abnormal stop state, and the power consumption of each molding cell 12 for each of the manual state. The power tallying unit 50 may also tally the average power consumption of each molding cell 12 for each of the molding state, the average power consumption of each molding cell 12 for each of the emergency stop state, the average power consumption of each molding cell 12 for each of the abnormal stop state, and the average power consumption of each molding cell 12 for each of the manual state. This allows the power consumption of each molding cell 12 to be grasped for each of multiple machine states.

[0035] In step S4, the power tallying unit 50 may tally the total power consumption in the molding state, the total power consumption in the emergency stop state, the total power consumption in the abnormal stop state, and the total power consumption in the manual state.

[0036] The total power consumption in the molding state is obtained by adding up the power consumption of each molding cell 12 in the molding state. The total power consumption in the emergency stop state is obtained by adding up the power consumption of each molding cell 12 in the emergency stop state. The total power consumption in the abnormal stop state is obtained by adding up the power consumption of each molding cell 12 in the abnormal stop state. The total power consumption in the manual state is obtained by adding up the power consumption of each molding cell 12 in the manual state. The power tallying unit 50 may also calculate the calculated value of each total power consumption (including the average, maximum, minimum, standard deviation, etc.). After this, the process proceeds to step S31 in FIG. 3.

[0037] (Second Counting Rule) As shown in Fig. 5A, the second counting rule classifies the multiple machine states of each molding cell 12 into multiple counting groups, and calculates the power consumption for each of these counting groups. The multiple machine states of the molding cell 12 are pre-classified into multiple counting groups. One or more machine states belong to a first counting group among the multiple counting groups. A second counting group among the multiple counting groups includes multiple machine states different from the machine states that belong to the first counting group.

[0038] In this embodiment, the multiple counting groups include, for example, a first counting group and a second counting group. The multiple machine states include, for example, a molding state, an emergency stop state, an abnormal stop state, and a manual state. The molding state belongs to the first counting group. The emergency stop state, the abnormal stop state, and the manual state belong to the second counting group.

[0039] The machine conditions classified into the first and second counting groups can be set as appropriate. In the second counting rule, a plurality of machine conditions may be classified into three or more counting groups.

[0040] If the user selects the second counting rule in step S1, the power consumption of the multiple molding cells 12 is counted according to the second counting rule. In this case, the process proceeds to step S5a in FIG. 5B.

[0041] In step S5a, the receiving unit 44 receives information indicating the machine status of the target for which power consumption belonging to each of the multiple counting groups is to be counted. Specifically, the user operates the operation unit 36 ​​of the power counting device 10 or the operation unit 24 of any one of the molding cells 12 to specify the machine status belonging to each of the multiple counting groups, and the receiving unit 44 receives the information. Then, the process proceeds to step S5b. In step S5b, the information acquiring unit 42 acquires information indicating the power consumption of the counting group of each molding cell 12. The information indicating the power consumption acquired by the information acquiring unit 42 in step S5b is associated with the information indicating the machine status accepted in step S5a. Therefore, the power consumption for each of the multiple counting groups can be calculated from the information acquired by the information acquiring unit 42. Then, the process proceeds to step S6.

[0042] In step S6, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S6), the process proceeds to step S5a. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S6), the process proceeds to step S7.

[0043] In step S7, the power tallying unit 50 tallys up the power consumption (power consumption amount or calculated power consumption value) for each of the molding cells 12 for each of the multiple tallying groups. In this embodiment, the power tallying unit 50 tallys up the power consumption of each of the molding cells 12 by dividing it into a first tallying group and a second tallying group. Specifically, the power tallying unit 50 tallys up, for example, the power consumption of the first tallying group for each of the molding cells 12 and the power consumption of the second tallying group for each of the molding cells 12. The power tallying unit 50 may also tally up the average power consumption of the first tallying group for each of the molding cells 12 and the average power consumption of the second tallying group for each of the molding cells 12. This makes it possible to grasp the power consumption of each of the molding cells 12 by dividing it into multiple tallying groups.

[0044] In step S7, the power tallying unit 50 may tally the total power consumption by adding up the power consumption amounts of the first tallying groups of each molding cell 12, and the total power consumption by adding up the power consumption amounts of the second tallying groups of each molding cell 12. The power tallying unit 50 may also calculate the calculated values ​​of each total power consumption. After this, the process proceeds to step S31 in FIG. 3.

[0045] 6A , in the third counting rule, the user specifies machine states that belong to multiple counting groups, and power consumption is counted for each of the multiple counting groups. In this embodiment, the multiple counting groups include, for example, a first counting group and a second counting group. Note that the number of counting groups may be three or more.

[0046] If the user selects the third counting rule in step S1, the power consumption of the multiple molding cells 12 is counted according to the third counting rule. In this case, the process proceeds to step S8 in FIG. 6B.

[0047] In step S8, the receiving unit 44 receives information indicating the machine status for which power consumption belonging to each of the plurality of counting groups is to be counted. Specifically, the user operates the operation unit 36 ​​of the power counting device 10 or the operation unit 24 of any one of the molding cells 12 to specify the machine status belonging to each of the plurality of counting groups, and the receiving unit 44 receives the information.

[0048] In this embodiment, the molding state and the manual state are designated as the machine states belonging to the first tallying group, and the emergency stop state and the abnormal stop state are designated as the machine states belonging to the second tallying group. After this, the process proceeds to step S9.

[0049] In step S9, the information acquisition unit 42 acquires information indicating the power consumption of each molding cell 12. The information indicating the power consumption acquired by the information acquisition unit 42 in step S9 is associated with the information indicating the machine status received in step S8. Therefore, the power consumption for each of the multiple counting groups can be calculated from the information acquired by the information acquisition unit 42. Then, the process proceeds to step S10.

[0050] In step S10, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S10), the process proceeds to step S8. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S10), the process proceeds to step S11.

[0051] In step S11, the power tallying unit 50 tallys up the power consumption (power consumption amount or calculated power consumption value) for each of the molding cells 12 for each of the multiple tallying groups. In this embodiment, the power tallying unit 50 tallys up the power consumption of each of the molding cells 12 by dividing it into a first tallying group and a second tallying group. This makes it possible to grasp the power consumption of each of the molding cells 12 by dividing it into multiple tallying groups. Furthermore, because the user can specify the machine states that belong to the tallying group, it becomes easier to grasp the power consumption of the molding cells 12 by desired item.

[0052] In step S11, the power tallying unit 50 may tally the total power consumption obtained by summing up the power consumption of the first counting group of each molding cell 12 and the total power consumption obtained by summing up the power consumption of the second counting group of each molding cell 12. The power tallying unit 50 may also calculate the calculated value of each total power consumption. After this, the process proceeds to step S31 in FIG. 3.

[0053] (Fourth Counting Rule) As shown in FIG. 7A, the fourth counting rule counts the power consumption required to mold non-defective products and the power consumption required to mold defective products separately.

[0054] If the user selects the fourth calculation rule in step S1, the power consumption of the multiple molding cells 12 is calculated according to the fourth calculation rule. In this case, the process proceeds to step S12a in FIG. 7B.

[0055] In step S12a, the information acquisition unit 42 acquires measurement data for each molding cell 12. The measurement data is, for example, the molding time required to mold one molded product. Note that the measurement data is not limited to the molding time, but may also include the mold temperature, mold clamping force, etc. After molding of one molded product is completed, the process proceeds to step S12b. In step S12b, the judgment unit 48 judges the quality of the molded product. The judgment unit 48 judges the quality of the molded product each time a molded product is molded (each cycle). The judgment unit 48 judges the quality of the molded product based on the measurement data of the molding cell 12 when molding the molded product. If the measurement data is the molding time required to mold one molded product, the judgment unit 48 judges the molded product to be good if the molding time is within a predetermined allowable time range, and judges the molded product to be defective if the molding time is not within the allowable time range.

[0056] If the determining unit 48 determines that the molded product is a non-defective product, the process proceeds to step S13. If the determining unit 48 determines that the molded product is a defective product, the process proceeds to step S14.

[0057] In step S13, the information acquisition unit 42 acquires information indicating the power consumption (power consumption amount) required to mold the molded product determined to be a good product. Hereinafter, the power consumption required to mold the molded product determined to be a good product may be referred to as the "power consumption during molding of a good product." After this, the process proceeds to step S15.

[0058] In step S14, the information acquisition unit 42 acquires information indicating the power consumption (power consumption amount) required to mold the molded product determined to be defective. Hereinafter, the power consumption required to mold the molded product determined to be defective may be referred to as the "power consumption during molding of the defective product." After this, the process proceeds to step S15.

[0059] In step S15, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S15), the process proceeds to step S12a. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S15), the process proceeds to step S16.

[0060] In step S16, the power tallying unit 50 tallys up the power consumption when a good product is molded and the power consumption when a defective product is molded in each molding cell 12. This makes it possible to grasp the power consumption of each molding cell 12 separately for cases where the molded product is a good product and cases where the molded product is a defective product.

[0061] In step S16, the power tallying unit 50 may tally the total power consumption obtained by summing up the power consumption of each molding cell 12 when molding a non-defective product, and the total power consumption obtained by summing up the power consumption of each molding cell 12 when molding a defective product. The power tallying unit 50 may also calculate the value of each total power consumption. After this, the process proceeds to step S31 in FIG. 3.

[0062] 8A , the fifth calculation rule calculates power consumption for each of a plurality of time periods. In this embodiment, the plurality of time periods includes a first time period (8:00 to 10:00), a second time period (10:00 to 13:00), a third time period (13:00 to 15:00), and a fourth time period (15:00 to 17:00). The plurality of time periods can be set as appropriate.

[0063] If the user selects the fifth counting rule in step S1, the power consumption of the multiple molding cells 12 is counted according to the fifth counting rule. In this case, the process proceeds to step S17a in FIG. 8B.

[0064] In step S17a, the reception unit 44 receives information indicating multiple time periods (e.g., first to fourth time periods) for which power consumption is to be totaled. Specifically, the user operates the operation unit 36 ​​of the power totalization device 10 or the operation unit 24 of any one of the molding cells 12 to specify multiple time periods, and the reception unit 44 receives the information. Then, the process proceeds to step S17b. In step S17b, the information acquisition unit 42 acquires information indicating the power consumption of each molding cell 12. The information indicating the power consumption acquired by the information acquisition unit 42 in step S17b is associated with the information indicating the multiple time periods received in step S17a. Therefore, the power consumption for each of the multiple time periods can be calculated from the information acquired by the information acquisition unit 42. Then, the process proceeds to step S18.

[0065] In step S18, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S18), the process proceeds to step S17a. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S18), the process proceeds to step S19.

[0066] In step S19, the power tallying unit 50 tallys the power consumption (power consumption amount or calculated value) of each molding cell 12 for each of a plurality of time periods. In this embodiment, the power tallying unit 50 tallys the power consumption of each molding cell 12 by dividing it into a first time period, a second time period, a third time period, and a fourth time period. Specifically, the power tallying unit 50 tallys, for example, the power consumption of each molding cell 12 for the first time period, the power consumption of each molding cell 12 for the second time period, the power consumption of each molding cell 12 for the third time period, and the power consumption of each molding cell 12 for the fourth time period. Note that the power tallying unit 50 may also tally the calculated value of the power consumption of each molding cell 12 for the first time period, the calculated value of the power consumption of each molding cell 12 for the second time period, the calculated value of the power consumption of each molding cell 12 for the third time period, and the calculated value of the power consumption of each molding cell 12 for the fourth time period. This makes it possible to grasp the power consumption of each molding cell 12 divided into a plurality of time periods.

[0067] In step S19, the power tallying device 10 may tally the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 in the first time slot, the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 in the second time slot, the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 in the third time slot, and the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 in the fourth time slot. Note that the power tallying unit 50 may calculate the calculated values ​​of each total power consumption. After this, the process proceeds to step S31 in FIG. 3.

[0068] 9A , the sixth calculation rule calculates the power consumption for each of a plurality of work time periods of operators who operate a plurality of molding cells 12. In this embodiment, the plurality of work time periods includes a first work time period (8:00 AM to 4:00 PM), a second work time period (4:00 PM to midnight), and a third work time period (12:00 AM to 8:00 AM). The plurality of work time periods can be set as appropriate.

[0069] If the user selects the sixth calculation rule in step S1, the power consumption of the multiple molding cells 12 is calculated according to the sixth calculation rule. In this case, the process proceeds to step S20a in FIG. 9B.

[0070] In step S20a, the reception unit 44 receives information indicating multiple work time periods (e.g., first to third work time periods) for which power consumption is to be totaled. Specifically, the user operates the operation unit 36 ​​of the power totalization device 10 or the operation unit 24 of any one of the molding cells 12 to specify multiple work time periods, and the reception unit 44 receives the information. Then, the process proceeds to step S20b. In step S20b, the information acquisition unit 42 acquires information indicating the power consumption of each molding cell 12. The information indicating the power consumption acquired by the information acquisition unit 42 in step S20b is associated with the information indicating the multiple work time periods received in step S20a. Therefore, the power consumption for each of the multiple work time periods can be calculated from the information acquired by the information acquisition unit 42. Then, the process proceeds to step S21.

[0071] In step S21, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S21), the process proceeds to step S20a. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S21), the process proceeds to step S22.

[0072] In step S22, the power tallying unit 50 tally the power consumption (power consumption amount or calculated value) of each molding cell 12 for each of the operator's multiple shift time slots. In this embodiment, the power tallying unit 50 tally the power consumption of each molding cell 12 for a first shift time slot, a second shift time slot, and a third shift time slot. Specifically, the power tallying unit 50 tally, for example, the power consumption of each molding cell 12 for the first shift time slot, the power consumption of each molding cell 12 for the second shift time slot, and the power consumption of each molding cell 12 for the third shift time slot. The power tallying unit 50 may also tally the calculated power consumption of each molding cell 12 for the first shift time slot, the calculated power consumption of each molding cell 12 for the second shift time slot, and the calculated power consumption of each molding cell 12 for the third shift time slot. This makes it possible to grasp the power consumption of each molding cell 12 for each of the multiple shift time slots.

[0073] In step S22, the power tallying device 10 may tally the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 during the first shift time slot, the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 during the second shift time slot, and the total power consumption obtained by summing up the power consumption amounts of each molding cell 12 during the third shift time slot. Note that the power tallying unit 50 may calculate the calculated values ​​of each total power consumption. After this, the process proceeds to step S31 in FIG. 3 .

[0074] (Seventh Counting Rule) As shown in FIG. 10A, the seventh counting rule counts power consumption for each of a plurality of job types designated by the user.

[0075] If the user selects the seventh calculation rule in step S1, the power consumption of the multiple molding cells 12 is calculated according to the seventh calculation rule. In this case, the process proceeds to step S23 in FIG. 10B.

[0076] In step S23, the job type information receiving unit 46 receives information indicating multiple job types for which power consumption is to be totaled. Specifically, the user operates the operation unit 36 ​​of the power totalization device 10 or the operation unit 24 of any one of the molding cells 12 to specify multiple job types, and the job type information receiving unit 46 receives the information. In this embodiment, mass production work, prototype work, setup work, and machine adjustment work are specified as the multiple job types.

[0077] The job type information receiving unit 46 may receive multiple job types by having the user input a job type code by operating the operation unit 36 ​​of the power tallying device 10. The job type code is a type code for identifying the content of the job type. The job type code is determined in advance and stored in the storage unit 34. The job type code can be set appropriately by the user. In this way, by using the job type code, frequently used job types can be easily input. After this, the process proceeds to step S24.

[0078] In step S24, the information acquisition unit 42 acquires information indicating the power consumption of each molding cell 12. The information indicating the power consumption acquired by the information acquisition unit 42 in step S24 is associated with the information indicating the multiple job types accepted in step S23. Therefore, the power consumption for each of the multiple job types can be calculated from the information acquired by the information acquisition unit 42. Then, the process proceeds to step S25.

[0079] In step S25, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S25), the process proceeds to step S23. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S25), the process proceeds to step S26.

[0080] In step S26, the power tallying unit 50 tallys the power consumption (power consumption amount or calculated value) for each of the multiple job types in each molding cell 12. In this embodiment, the power tallying unit 50 tallys the power consumption of each molding cell 12 by dividing it into mass production work, prototype work, setup work, and machine adjustment work. Specifically, the power tallying unit 50 tallys, for example, the power consumption of each molding cell 12 for mass production work, the power consumption of each molding cell 12 for prototype work, the power consumption of each molding cell 12 for setup work, and the power consumption of each molding cell 12 for machine adjustment work. Note that the power tallying unit 50 may also tally the calculated power consumption of each molding cell 12 for mass production work, the calculated power consumption of each molding cell 12 for prototype work, the calculated power consumption of each molding cell 12 for setup work, and the calculated power consumption of each molding cell 12 for machine adjustment work. This allows the power consumption of each molding cell 12 to be determined by multiple job types.

[0081] In step S26, the power tallying unit 50 may tally the total power consumption obtained by adding up the power consumption of the mass production work of each molding cell 12, the total power consumption obtained by adding up the power consumption of the prototype work of each molding cell 12, the total power consumption obtained by adding up the power consumption of the setup work of each molding cell 12, and the total power consumption obtained by adding up the power consumption of the machine adjustment work of each molding cell 12. The power tallying unit 50 may also calculate the value of each total power consumption. After this, the process proceeds to step S31 in FIG. 3.

[0082] 11A , in the eighth calculation rule, the user specifies a job type that belongs to multiple job type calculation groups, and power consumption is calculated for each of the multiple job type calculation groups. The multiple job type calculation groups include, for example, a first job type calculation group, a second job type calculation group, and a third job type calculation group. The number of job type calculation groups may be two or four or more.

[0083] If the user selects the eighth calculation rule in step S1, the power consumption of the multiple molding cells 12 is calculated according to the eighth calculation rule. In this case, the process proceeds to step S27 in FIG. 11B.

[0084] In step S27, the job type information receiving unit 46 receives information indicating the job types belonging to each of the multiple job type counting groups for which power consumption is to be calculated. Specifically, the user operates the operation unit 36 ​​of the power calculation device 10 or the operation unit 24 of any one of the molding cells 12 to specify the job types belonging to each of the multiple job type counting groups, and the job type information receiving unit 46 receives the information. In this embodiment, mass production work is specified as the job type belonging to the first job type counting group. Furthermore, prototype work is specified as the job type belonging to the second job type counting group. Furthermore, setup work and machine adjustment work are specified as job types belonging to the third job type counting group. After this, the process proceeds to step S28.

[0085] In step S28, the information acquisition unit 42 acquires information indicating the power consumption of each molding cell 12. The information indicating the power consumption acquired by the information acquisition unit 42 in step S28 is associated with the information indicating the job type accepted in step S27. Therefore, the power consumption for each of a plurality of job type counting groups can be calculated from the information acquired by the information acquisition unit 42. Then, the process proceeds to step S29.

[0086] In step S29, the determination unit 48 determines whether the conditions for power tallying are satisfied. If the determination unit 48 determines that the conditions for power tallying are not satisfied (NO in step S29), the process proceeds to step S27. If the determination unit 48 determines that the conditions for power tallying are satisfied (YES in step S29), the process proceeds to step S30.

[0087] In step S30, the power tallying unit 50 tallys the power consumption (power consumption amount or calculated value) for each of the molding cells 12 for each of the multiple job type tally groups. In this embodiment, the power tallying unit 50 tallys the power consumption of each of the molding cells 12 by dividing it into a first job type tally group, a second job type tally group, and a third job type tally group. Specifically, the power tallying unit 50 tallys, for example, the power consumption of each of the molding cells 12 for the first job type tally group, the power consumption of each of the molding cells 12 for the second job type tally group, and the power consumption of each of the molding cells 12 for the third job type tally group. The power tallying unit 50 may also tally the calculated power consumption of each of the molding cells 12 for the first job type tally group, the calculated power consumption of each of the molding cells 12 for the second job type tally group, and the calculated power consumption of each of the molding cells 12 for the third job type tally group. This allows the power consumption of each of the molding cells 12 to be grasped by dividing it into multiple job type tally groups.

[0088] In step S30, the power tallying unit 50 may tally the total power consumption obtained by summing up the power consumption amounts of the first job type tallying groups of each molding cell 12, the total power consumption obtained by summing up the power consumption amounts of the second job type tallying groups of each molding cell 12, and the total power consumption obtained by summing up the power consumption amounts of the third job type tallying groups of each molding cell 12. The power tallying unit 50 may also calculate the calculated value of each total power consumption. After this, the process proceeds to step S31 in FIG. 3.

[0089] In step S31, the display control unit 52 displays the tally results on at least one of the display units 26 and 38. This allows the user to easily understand the tally results. The display control unit 52 may display the display results as a table or graph on either the display unit 26 or 38. After this, the processing shown in FIG. 3 is completed.
