Description

  The present invention relates to a work content specifying apparatus, a work content specifying method, and a program for analyzing and specifying work content.

In the printing industry, when a job is received, a printed matter is delivered through the following work process.
(1) Creation of order slips (2) Creation of work instructions (3) Production planning and delivery planning (4) Production of printed materials (5) Delivery of printed materials

  Here, the operator who operates the printing machine often performs the work of the process (4) according to the work instruction document, and then writes the work time by handwriting in the daily work report. In the daily work report, in addition to the name of the worker, the start time and the end time of the work are described for each received work.

  However, since the worker does not enter the work start time and end time in the daily work report in real time, these times may be inaccurate.

  Next, in order to facilitate understanding, the operation of each component of the work analysis system will be described by taking as an example the case of a single printing machine 30.

(Power consumption memory processing)
In order for the work analysis apparatus 10 to specify the content of the work being performed in the printing machine 30 based on the power consumption of the printing machine 30, the power consumption of the printing machine 30 needs to be stored in the power consumption DB 143. There is. Therefore, a process in which the power meter 20 stores the power consumption of the printing press 30 in the power consumption DB 143 of the work analysis apparatus 10 will be described.

  After the installation, the control unit 250 of the power meter 20 starts the process shown in FIG. 7B, and first resets the time lapse (t) of the time measuring unit 290 to 0 and restarts the time measurement (step S1). ). The controller 250 determines whether or not the elapsed time (t) of the timer 290 is equal to or longer than a predetermined time (T1) (step S2). This time (T1) corresponds to a period in which the power measuring device 20 transmits the power consumption of the printing press 30 to the work analysis apparatus 10.

  When determining that the elapsed time (t) is less than the predetermined time (T1) (step S2; No), the control unit 250 repeats step S2. On the other hand, when it is determined that the elapsed time (t) is equal to or greater than the predetermined time (T1) (step S2; Yes), the control unit 250 reads the power consumption of the printing press 30 from the integration buffer unit 285 (step S2). S3). The control part 250 reads the identification information of the self-power measuring device 20 from the memory | storage part 250 (step S4). The control unit 250 transmits a data reception request to the work analysis apparatus 10 via the communication unit 210 (step S5). Here, the control unit 250 includes the power consumption read in step S3 and the identification information read in step S4 in association with the reception request argument.

  In response to the reception request from the power meter 20, the control unit 150 of the work analysis apparatus 10 starts the process illustrated in FIG. 7A, and first receives data (step S6). The control unit 150 acquires the current time (time stamp) from the timer 151 (step S7). For each piece of identification information included in the received data, the control unit 150 stores the power consumption included in the received data in association with the time acquired in step S6 in the power consumption DB 143 (step S8). The control unit 150 transmits a notification that the recording of power consumption is complete (recording completion notification) to the power meter 20 (step S9).

  The control unit 250 of the power meter 20 receives a recording completion notification from the work analysis apparatus 10 (step S10). Thereafter, the control returns to step S1, and the control unit 250 repeats the same processing. Thereby, the power consumption of the printing press 30 and the time when the power consumption is detected are stored in the power consumption DB 143 in association with each other.

(Power consumption display processing)
Next, a process in which the work analysis apparatus 10 displays data stored in the power consumption DB 143 will be described.

  The user operates the operation unit 120 of the work analysis apparatus 10 and gives an instruction to display data stored in the power consumption DB 143. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 extracts a record including the time included in the time range specified by the user from the power consumption DB 143. As shown in FIG. 8, the control unit 150 displays on the display unit 130 a graph (power consumption graph) in which a point indicating a set of the power consumption and time of the extracted record is plotted. In the present embodiment, the control unit 150 displays adjacent points connected by a straight line. Thereby, the change of the power consumption with time can be easily grasped at a glance.

(Work analysis process)
Next, processing in which the work analysis apparatus 10 analyzes work performed on the printing press 30 will be described. The user operates the operation unit 120 of the work analysis apparatus 10 and gives an instruction to analyze the content of the work performed on the printing press 30 on the specified date. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 starts the processing shown in FIGS. 9 to 10 and displays the contents of the work performed on the printing press 30 from 0:00 to 24:00 on the day of the instruction. analyse. In this embodiment, the control unit 150 analyzes the work content in the time range from 0:00 to 24:00, but analyzes the work content in the time range instructed by the user. Also good.

  The control unit 150 of the work analysis apparatus 10 resets the values of the indexes k and i to 0 (step S11). The control unit 150 substitutes k * Δt (Δt: time increment in the power consumption DB 143 shown in FIG. 4) into the array T (k) (step S12). The power consumption associated with the time T (k) is read from the power consumption DB 143 (step S13). The control unit 150 substitutes the read power consumption into the array P (k) (step S14). The control unit 150 determines whether or not k ≠ 0 (step S15). When the control unit 150 determines that k ≠ 0 (step S15; Yes), whether P (k) and P (k−1) are both included in the same power consumption range of the work condition DB 142. In other words, it is determined whether or not a condition that P (k) and P (k−1) are regarded as identical is satisfied (step S16). On the other hand, when it is determined that k ≠ 0 is not satisfied (step S15; No), the control unit 150 jumps to step S24.

  When the control unit 150 determines that both P (k) and P (k−1) are included in the same power consumption range of the work condition DB 142 (step S16; Yes), the control unit 150 sets the array I (k). (I + 1) * Δt is substituted (step S17). The control unit 150 increments the value of the index i by +1 (step S18).

  On the other hand, if the control unit 150 determines that both P (k) and P (k−1) are not included in the same power consumption range of the work condition DB 142 (step S16; No), the power consumption P The work content associated with the set of (k-1) and duration I (k-1) is read from the work condition DB 142 (step S20). The control unit 150 substitutes T (k-1) -I (k-1) for the variable Ts indicating the work start time (step S21). The control unit 150 substitutes T (k−1) for the variable Te indicating the work end time (step S22). The work content read in step S20, the start time Ts, and the end time Te are associated with each other and stored in the daily report DB 144 (step S23). The control unit 150 resets the value of the array I (k) to 0 (step S24). The control unit 150 resets the value of the index i to 0 (step S25). Thereafter, control jumps to step S19.

  The control unit 150 increments the value of the index k by +1 (step S19). Thereafter, the control returns to step S12, and the control unit 150 repeats the same processing until k> 24 * 60 * 60 (seconds) / Δt (step S26).

  When it is determined that k> 24 * 60 * 60 (seconds) / Δt is satisfied (step S26; Yes), the control unit 150 ends the work analysis process. As a result, the daily work DB 144 stores the work contents performed by the printing press 30 and the start time and end time thereof.

(Power consumption display processing)
Next, a process in which the work analysis apparatus 10 displays data stored in the daily report DB 144 will be described.

  The user operates the operation unit 120 of the work analysis apparatus 10 and gives an instruction to display the data stored in the daily report DB 144. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 displays the work content, the start time, and the end time stored in the daily report DB 144 in association with each other on the display unit 130. Thereby, it is possible to easily grasp the start time and the end time for each work content at a glance.

  As described above, according to the present embodiment, the work content performed by the printing press 30 is specified according to the combination of the power consumption of the printing press 30 and the duration of the power consumption. For this reason, the work content can be specified without a report from the worker.

  Also, based on the change in power consumption of the printing press 30, the work start time and the work end time are specified. For this reason, the start time and end time of work can be recorded automatically and accurately.

(Embodiment 2)
In the first embodiment, the work content performed by the printing press 30 is specified according to the combination of the power consumption of the printing press 30 and the duration of the power consumption. In the second embodiment, a work analysis system capable of specifying which company the specified work content belongs to from which work has been received will be described.

  Here, the configuration of the work analysis system according to the second embodiment is the same as that of the work analysis system according to the first embodiment. However, the storage unit 140 of the work analysis apparatus 10 includes an order receiving DB 145 that stores information on received work, a standard power consumption DB 146 by specification that stores power consumption of the printing machine 30 per printed matter, and a predetermined method. And an order-by-order daily report DB 147 in which the order DB 145 and the daily report DB 144 are combined. Specifically, as shown in FIG. 11, the order DB 145 stores an order number, a customer name, the number of copies, a product name, and a printing specification in association with each other. “Printing specifications” include, for example, paper quality, paper size, type of color used, number of pages per copy, and the like.

  Specifically, the standard power consumption DB 146 by specification, as shown in FIG. 12, the printing specifications, the power consumption (standard power consumption) of the printing press 30 per sheet when printing according to this specification, and this The time per sheet (standard time) required when printing with power consumption is associated and stored. Further, the daily report by order DB 147 is specifically derived from the order number, customer name, number of copies, product name, printing specifications, and daily report DB 144 derived from the order DB 145, as shown in FIG. The work start time and work end time are stored in association with each other.

(Order information registration process)
When a user receives an order for a job from a customer, it is necessary to register the order information (order number, customer name, number of copies, product name, printing specifications, etc.) in the order DB 145. The user operates the operation unit 120 to give an instruction to register order information. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 stores the order number, the customer name, the number of copies, the product name, and the printing specification input from the operation unit 120 in association with each other in the order receiving DB 145. As a result, the order information is registered in the order DB 145 as shown in FIG.

(Work analysis process)
Next, the user operates the operation unit 120 of the work analysis apparatus 10 and gives an instruction to analyze the content of the work performed on the printing press 30 on the specified date. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 starts the processing shown in FIGS. 9 to 10 and displays the contents of the work performed on the printing press 30 from 0:00 to 24:00 on the day of the instruction. Analyze and update the daily report DB 144 in the same manner as in the first embodiment.

(DB join processing)
Subsequently, the user operates the operation unit 120 of the work analysis apparatus 10 to instruct to create the daily report DB 147 by order by combining the order DB 145 and the daily report DB 144. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 starts the processing shown in FIGS. 14 to 15 and first extracts a record whose work content is “print” from the daily report DB 144 (step S31).

  The control unit 150 resets the value of the index k to 0 (step S32). The control unit 150 reads the kth record among the records extracted in step S31 (step S33). The control unit 150 integrates the power consumption of the power consumption DB 143 in the range from the start time to the end time of this record (step S34). The control unit 150 substitutes a value (that is, work (Joule)) obtained by the integration into the array W (k) (step S35).

  The control unit 150 resets the value of the index i to 0 (step S36). The control unit 150 reads the i-th record in the order entry DB 145 (step S37). The control unit 150 reads “standard power consumption” and “standard time” associated with “specification” of this record from the standard power consumption DB 146 by specification (step S38). The control unit 150 includes the number of pages per copy included in the “specification” of the record read in step S38, the “number of copies”, the “standard power consumption” read in step S39, and the “standard time”. The product (that is, the work amount (Joule) necessary for creating the printed matter related to the order) is substituted into the array WS (k) (step S39). The control unit 150 determines whether or not W (k) ≠ WS (i) is satisfied (step S40). Here, when WS (i) −ε <W (k) <WS (i) + δ (ε, δ: positive threshold value), the control unit 150 satisfies W (k) = WS (i). Determine.

  When determining that W (k) ≠ WS (i) is satisfied (step S41; Yes), the controller 150 increments the value of the index i by +1 (step S41). The control unit 150 determines whether or not the i-th record in the order entry DB 145 is the last record (step S42).

  On the other hand, when it is determined that W (k) ≠ WS (i) is not satisfied (that is, W (k) = WS (i)) (step S41; No), the control unit 150 is the i-th item in the order DB 145. The order number, the customer name, the number of copies, the product name, the specification, and the start time and the end time of the kth record among the records extracted in step S31 are associated with each other by order. Store in the daily report DB 147 (step S43). Thereafter, control jumps to step S45.

  The control unit 150 increments the value of the index k by +1 (step S44). Thereafter, the control returns to step S34, and the control unit 150 repeats the same processing until the record extracted in step S31 becomes the last record (step S45). On the other hand, when determining that the record is the last record (step S46; Yes), the control unit 150 ends the process. As a result, the order DB 145 and the daily report DB are combined to create a daily report DB 147 by order.

  As described above, according to the present embodiment, based on the work (Joule) performed by the printing press 30, the work content performed by the printing press 30 and the order information are combined. For this reason, it is possible to accurately specify the start time and the end time of the work for each received work.

  In the present embodiment, the start time and end time of the work content “print” are set as the start time and end time of the work of the received work, but “print” and “preparation” just before the work content “print” The start time and the end time may be specified including any work content such as “”.

(Embodiment 3)
In the first embodiment, the work content performed by the printing press 30 is specified according to the combination of the power consumption of the printing press 30 and the duration of the power consumption. In the third embodiment, a work analysis system capable of giving a warning when work efficiency is poor will be described.

  Here, the configuration of the work analysis system according to the third embodiment is the same as that of the work analysis system according to the first embodiment. However, the storage unit 140 of the work analysis apparatus 10 further includes an order receiving DB 145 of the second embodiment and a standard time DB 148 by specification that stores time (standard time) required for each printed matter in each work content. Yes. Specifically, the specification-specific standard time DB 148 stores a set of print specifications and work contents and a standard time in association with each other, as shown in FIG. Further, as shown in FIG. 17, the daily report DB 144 further stores an “order number” common to the order DB 145 and an “excess time” indicating a difference between the work time and the standard value in association with each other.

(Work analysis process)
The user operates the operation unit 120 of the work analysis apparatus 10 and gives an instruction to analyze the content of the work performed on the printing press 30 on the specified date. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 starts the processing shown in FIGS. 9 to 10 and displays the contents of the work performed on the printing press 30 from 0:00 to 24:00 on the day of the instruction. Analyze and update the daily report DB 144 in the same manner as in the first embodiment. However, at this time, no value is entered in the order number and overtime fields of the daily report DB 144.

(Order number input process)
Next, the user operates the operation unit 120 of the work analysis apparatus 10 to instruct the daily report DB 144 to input an order number. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 stores the order number for each work content input from the operation unit 120 in the daily report DB 144.

(Working time analysis process)
Subsequently, the user operates the operation unit 120 of the work analysis apparatus 10 and gives an instruction to analyze the work time. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 starts the processes shown in FIGS. 18 to 19 and first resets the value of the index k to 0 (step S51). The control unit 150 reads the kth record from the daily report DB 144 (step S52). The control unit 150 determines whether or not the “work content” of this record is other than “stop” (step S53).

  When the “work content” is other than “stop” (step S53; Yes), the control unit 150 reads from the order reception DB 145 a record including the “order number” that is the same as the “order number” of the record read in S52. (Step S54). On the other hand, when the “work content” is “stop” (step S53; No), the control unit 150 jumps to step S60. The control unit 150 reads “standard time” associated with the set of “specification” of the record read in S54 and “work content” of the record read in S52 from the standard time DB 148 by specification (step S55).

  The control unit 150 adds, to the variable ST indicating the standard value of the working time, the number of pages per copy included in the “specification” of the record read in S54, the “number of copies”, and the “standard time” read in S55. Is substituted (step S56). The control unit 150 assigns the difference between the “end time” and “start time” of the record read in S52 to the variable RT indicating the actual work time (step S57). The control unit 150 substitutes (RT-ST) for the variable ET indicating the excess time (step S58). The control unit 150 updates the daily report DB 144 with a record in which the value of the variable ET is set in the “excess time” of the record read in S52 (step S59). The control unit 150 increments the value of the index k by +1 (step S60). Then, the control returns to step S52, and the control unit 150 repeats the same processing until the daily report DB record becomes the last record. (Step S61). On the other hand, when determining that the record is the last record (step S61; Yes), the control unit 150 ends the process. Thereby, as shown in FIG. 17, the excess time for each work content is stored in the daily report DB 144.

(Warning list display processing)
Next, the user operates the operation unit 120 of the work analysis apparatus 10 to give an instruction to list items whose excess time for each work content exceeds a predetermined threshold. In response to this instruction, the operation unit 120 transmits a signal indicating the instruction to the control unit 150. In response to the signal, the control unit 150 extracts a record in which the “excess time” exceeds a predetermined threshold from the daily report DB 144. Based on the “order number” common to the daily report DB 144 and the order DB 145, the control unit 150 combines the extracted record set and the order DB 145. As shown in FIG. 20, the control unit 150 displays a warning list including the combined table on the display unit 130. According to this, for example, when the work content is “preparation” and the time is exceeded, it is possible to estimate the possibility that a human problem such as a worker's neglect has occurred. In addition, when time is exceeded in the process of “printing out” the work content, the possibility that a technical trouble has occurred can be estimated. Further, when the work content is overrun in the process of “main printing”, due to inadequate maintenance of the printing press 30, the power consumption of the printing press 30 is reduced to other physical work such as friction (Joule ) Can be estimated. For this reason, the problem of each work content can be grasped quickly.

  As described above, according to the present embodiment, the warning list is displayed for each work content based on the excess time from the standard value of the work time. For this reason, it is possible to quickly grasp the process in which waste occurs.

  In the present embodiment, the warning list is displayed based on the excess time from the standard value of the work time. However, the warning list may be displayed based on the power consumption and work amount of the printing press 30. .

  In the present embodiment, when the power consumption for a predetermined period (one day) is stored in the power consumption DB 143, work analysis processing, work time analysis processing, and the like are performed. When the power consumption of 30 is received, work analysis processing and work time analysis processing may be performed at any time, and a warning may be issued immediately when the work time exceeds the standard value. According to this, a warning can be given to an operator quickly.

  The present invention is not limited to the above embodiment, and various modifications and applications are possible. For example, you may make it memorize | store the generation amount of the carbon dioxide for every work content further in the daily report DB144. In this case, for each record in the daily report DB 144, the control unit 150 reads the power consumption associated with the work content from the work condition DB 142, and obtains this power consumption from the difference between the end time and the start time of this record. The amount of carbon dioxide generated is obtained by multiplying the working time by the amount of dioxide generated per unit work stored in advance in the storage unit 140. According to this, it is possible to easily grasp the amount of generated dioxide for each work content.

  Similarly, the generated amount of carbon dioxide corresponding to the excess time for each work content may be displayed in the work warning list. In this case, the control unit 150 reads the power consumption associated with the work content of the warning list from the work condition DB 142, and the power consumption is calculated based on the difference between the end time and the start time of the warning list. The amount of carbon dioxide generated is obtained by multiplying the amount of generated dioxide per unit work stored in advance in the storage unit 140. According to this, the amount of carbon dioxide generated by useless work can be easily recognized. For this reason, an incentive to reduce the generation of carbon dioxide acts on the user, and unnecessary work is reduced.

  Further, in the present embodiment, the work content performed by the printing press 30 is specified based on the power consumption of the printing press 30 and the duration of the power consumption. However, the printing press 30 instead of the power consumption. The work content may be specified based on the magnitude of the generated operation sound and its duration. According to this, it is possible to specify work contents with a single volume measuring device for a plurality of printing machines 30.

  Moreover, in this embodiment, whenever the power measuring device 20 measures power consumption, the measured power consumption is transmitted to the work analysis apparatus 10, but CSV (Comma Separated Values) storing power consumption for one day is stored. ) A file such as a file may be transmitted once a day at a predetermined time. In this case, the power measuring device 20 stores the measured power consumption and the time when the power consumption is measured in association with each other in this file.

  In the present embodiment, the printing machine 30 has been described as an example for specifying the work content, but other devices other than the printing machine 30 may be used.

  In the present embodiment, the work analysis device 10 and the power measuring device 20 are configured as separate devices, but they can be replaced by a single device.

  Furthermore, although the program executed by the control unit 150 has been described as being stored in the program storage unit 141, the program may be obtained from an external storage medium or transmitted via a network. It may be stored.

  The present invention can be used for devices whose power consumption changes according to work.
