Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production management apparatus that generates trace information in a process in which a plurality of devices perform a process.

[0002]

2. Description of the Related Art For example, in the manufacturing process of food, the final step is to manufacture the manufactured product into a container such as a can
There is a filling and packaging process of filling a bottle and packaging. In this filling and packaging step, first, a container for filling the product, for example, an empty can, is unloaded by a depalletizer and conveyed to a filler (filling machine) by an empty can conveyor. The transported cans are filled with products by a filler. The empty can filled with the product is transported to the capper (seamer) as an actual can. The cap of the real can transferred to the capper is tightened by the capper, and then transferred to the caser by the real can conveyor. During the transportation to the caser, the abnormal cans are discharged by various inspection machines. For example, the weight, level and internal pressure are checked. The cans in which no abnormality is found are packed in a box by a caser, transported to a palletizer by a case conveyor, numbered for each product pallet by the palletizer, and shipped.

In this filling and packaging process, the processing is carried out in each device at a speed of 500 lines / min to 2000 lines / min. Consumers in the food industry have a very strict eye, and since the filling and packaging process is the final process for the consumer, it is necessary to pay close attention to the detection of the abnormality.

When an abnormality is detected, the trace information is used to pursue the cause of the abnormality. This trace information is generated by a preset transit time for each device, and is composed of device information, time information, and lot number information for a single product or a lot. Specifically, the production management device reads information from the depalletizer, which is the first processing device in the filling and packaging process,
Generation of trace information is started. After that, the trace information is sequentially generated according to the preset elapsed time for each device and the theoretical elapsed time between the devices.

However, the trace information generated by the conventional method has the following problems. That is, the trace information including the device information, the time information, the lot number information, and the like is generated according to the scheduled transit time. So, for example,
When the device is stopped due to the generation of an alarm, the product stays, so that there is a difference from the preset transit time. As a result, there is a problem that the accuracy of the trace information decreases. Further, since the trace information is generated by the preset elapsed time for each device and the theoretical elapsed time between each device, the accuracy of the trace information itself is low,
In the unlikely event of a trouble, it was necessary to suspend a large amount of shipment for safety.

Therefore, the present invention has been made to solve such a problem, and its purpose is to generate highly accurate trace information and to search this trace information to obtain the time for each device. It is to provide a production control device that makes it easy to identify the cause of an anomaly and the anomalous product by specifying the lot number and the lot number.

Next, the processing procedure of the lot trace processing section 1-1 will be described with reference to FIGS. 9 to 15. The user inputs data by operating the operation unit 1-5 (S901). For example, in the display unit 1-4, FIG.
As shown in 0, GUI (Graphical User Interface)
The input screen by is displayed. The user can input data by operating the operation unit 1-5 while looking at this input screen. For example, on the search condition input / execution screen shown in FIG. 10, first, the device name is selected. For example, a list box in which each device used in the filling and packaging process is displayed may be used, and a device to be searched may be selected from the displayed devices. For example, in the filling and packaging process, a filler is selected when an abnormality is found in the product to be filled, and a palletizer or a caser is selected when an abnormality is found in the final product.

Next, the conditions are selected. For example, it is possible to search by lot number, actual number, and time. When searching by time, you can further specify the time and time range. For example, as shown in FIG. 11A, when “search by the number of achievements” is selected as a condition, an edit box for specifying the number of achievements is displayed. As shown in FIG. 11B, when “Search by lot number” is selected as the condition, an edit box for designating the lot number is displayed. As shown in FIG. 12A, when "Search by time (year / month / day hour: minute)" is selected as the condition, an edit box for designating the date and time is displayed.

As shown in FIG. 12B, when "Search by time (year / month / day hour: minute to hour: minute)" is selected as a condition, an edit for specifying the date and time range is performed. A box and a command button described as "alarm history" are displayed. Here, by selecting and clicking the command button described in “alarm history” with the mouse, for example, the command button shown in FIG.
An alarm history screen as shown in 4 is read from the alarm history database 1-8 and displayed.

The user selects the alarm that he wants to search. By doing so, the generation time and recovery time of the selected alarm are automatically entered in the edit box of the time range.

Alternatively, the time range may be input by the keyboard without selecting the "alarm history" command button. Note that each condition may be selected by providing a radio button in the vicinity of the area in which the options are displayed and clicking the radio button.

Next, a case of searching by the number of achievements will be described. "Filler" as the device and "Search by the actual number" as the condition
The case where is selected and "50000" is input as the number of achievements will be described (S901). In the search condition input / execution screen shown in FIG. 10, when the command button displayed as “execution” is selected and clicked, the lot trace processing unit 1-1 selects the file from the lot trace database 1-6. Read the number of achievements (S90
2). For example, in the lot trace database shown in FIGS. 7 and 8, the actual number of fillers is read. Next, if the safety factor is set for each device, the safety factor of the selected device is read from the safety factor master file 1-9 (S903).

Next, a count value is calculated from the safety factor read from the safety factor master file 1-9 and the actual number read from the lot trace database 1-6 in S902 (S904). In the safety factor master file 1-9, as shown in FIG. 13, the safety factor and its unit are stored for each device, and the count value is calculated by the product of this safety factor and the actual number. Next, the lot trace database 1-6 is accessed, and the lot number and time having the actual number close to the calculated count value are read out for each device (S905).

Next, the lot number and time are specified for the lot having the actual number closest to the count value. (S906). Next, together with the lot number and time read in S905, the lot number and time for each specified device are displayed on the display unit 1-4 (S907).
In this case, when they are arranged in time series in ascending order of time, the lots having the actual value close to the specified count number are displayed at the center. By doing so, the lot number and time of each specified device can be easily seen. Further, for example, the lot number and the time of each specified device may be displayed by shading.

Next, the case of searching by lot number will be described. A case will be described in which "depalletizer" is selected as the apparatus, "search by lot number" is selected as the condition, and "xx021" is input as the lot number.
Similar to the case of searching by the number of records, on the search condition input / execution screen shown in FIG. 10, when the command button displayed as “execution” is selected and clicked, the lot trace processing unit 1-1 displays Lot trace database 1-
The lot number in the depalletizer is read from 6, and the time, the lot number, and the actual number corresponding to the inputted lot number “xx021” are specified.

For example, in the lot trace database shown in FIG. 7, the lot number "xx021" in the depalletizer is "9:40" at the time, and the lot number "2".
It can be seen that the number is “1” and the actual number is “63000”. Next, the time, the lot number, the lot number, and the actual number are specified for each device, for example, the filler based on the actual number “63000”. The lot trace processing unit 1-1 refers to the lot trace database 1-6, and the actual number is 630.
The time, the number of lots, and the lot number of a lot near 00 are searched. As a result, in the lot trace database shown in FIG. 7, it can be seen that the lot corresponding to the lot number “A004” at the time “10:45” with the actual number “61907”.

As for the capper, caser, and palletizer, the time, the lot number, the number of lots, and the number of records are specified as in the filler. As a result, in the lot trace database shown in FIG. 7, the capper is identified as the lot with the lot number “B031” at the time “10:45” when the actual number is “61902”. Further, in the lot trace database shown in FIG. 8, the time “1” when the actual number of labelers is “60577”.
For the lot and caser with the lot number “C033” of 1:10 ”, the time“ 1 ”when the actual number is“ 61728 ”
2:20 ", lot number" B19999061745 lot ", palletizer at time" 13:10 "when the actual number is 61920," lot number C19990 "
61816 "lot.

The time specified for each device, the lot number, and the actual number are displayed as a quality control screen as shown in FIG. 15, for example. The quality control screen is composed of a search condition display area and an area for displaying trace information in each device. The process and the search condition are displayed in the area for displaying the search condition. As the search condition, when the lot number is searched, the lot number is displayed, and when the actual number is searched, the actual number is displayed. In the area for displaying the trace information in each device, the time, the lot number, the number of lots, and the number of records are displayed for each device, for example, in the order of earlier time.

Further, the lots having the lot number corresponding to the search condition are displayed in the center. By doing so, it can be made easier to see. Further, the lot number and the time of each specified device may be displayed by shading. By doing so,
The lot number and time of each specified device can be easily seen.

Next, a case of searching by time will be described. A case will be described in which "depalletizer" is selected as the device, "search by time (year / month / day hour: minute)" is selected as the condition, and "9:35" is input as the time. Similar to the case of searching by the lot number and the actual number, the command button displayed as "execute" is selected and clicked on the search condition input / execution screen shown in FIG. -1 reads the time in the depalletizer from the lot trace database 1-6, and specifies the lot number, the lot number, and the actual number corresponding to the input time "9:35". For example,
In the lot trace database 1-6 shown in FIG. 7, the time “9:35” in the depalletizer is the lot number “xx020”, the lot number “20”, and the actual number “60”.
It turns out that it is a lot of "000".

Next, based on the actual number "60000",
For each device, for example, a filler, a lot number, a lot number, and an actual number are specified. Lot trace processing section 1-1
Refers to the lot trace database 1-6, and retrieves the time when the lot having the actual number of about 60000 was processed, the number of lots, and the lot number. As a result, it can be seen that the lot corresponding to the lot number “A003” at the time “10:40” at which the number of achievements is “59910” corresponds.

As for the capper, caser, and palletizer, the time, the lot number, the number of lots, and the number of records are specified as in the filler. As a result, the number of achievements for the capper is “59905”, the time is “10:40”, the lot number is “B030”, and the number of achievements is “5” for the labeler.
7574 ”at the time“ 11:05 ”, the lot number“ C032 ”, and the caser have a track record of“ 5 ”.
9376 "at the time" 12:15 ", lot number" B19999061744 "at the lot and palletizer at the actual number" 60000 "at the time" 13: 0 "
5 "and lot number" C19990661815 ". The time specified for each device, the lot number, and the actual number are displayed as a quality control screen as shown in FIG. 15, as in the case of searching by the lot number.

According to the production management apparatus of the embodiment, the accuracy of the trace information can be improved by storing the trace information together with the time information when the actual trace information is read from the controller. Further, the user can recognize the trace information of each device corresponding to the trace information of the designated device.

In other words, the time and lot in each device can be specified from highly accurate trace information. Therefore, for example, when a problem occurs in a product in the downstream device, it is possible to specify the time when the product is processed in the upstream device and lot information. Easy to pursue. On the contrary, if a trouble occurs in the raw material in the upstream device, the time and lot when the device in the downstream device is processed can be specified, so the product related to the trouble is pursued. Can be done easily.

Next, the case of searching within the time range will be described. "Search by time (year / month / day hour: minute to hour: minute)
The case where is selected will be described with reference to FIG. Here, “Filler” is selected as the device, “Search by time (year / month / day hour: minute to hour: minute) is selected as the condition (S1601), and the alarm history is selected (S1602).
An alarm has been designated (S1603). Similar to the case of searching by the number of records, in the search condition input / execution screen shown in FIG. 10, when the command button displayed as “execute” is selected and clicked, the lot trace processing unit 1
-1 reads the number of achievements from the alarm generation time to the recovery time in the device in which the alarm is generated from the lot trace database 1-6 (S1604).

Next, the lot trace database 1-6
From, the actual number in the filler is read (S160
5). Next, the safety factor is read from the safety factor master file 1-9 (S1606), and from the actual number of times from the alarm occurrence time to the recovery time in the device in which the alarm has occurred and the actual number in the filler and the read safety factor. Each count value is calculated (S1607). For example,
As described in the case of searching by the actual number, the count value from the alarm occurrence time to the recovery time is the product of the actual number from the alarm occurrence time to the recovery time and the safety factor, and the count value in the filler is the actual number. Calculated by the product of the safety factor.

Next, the lot number and time are read out for each device based on the count value calculated from the actual number from the alarm generation time to the recovery time in the device in which the alarm was issued (S1608). Next, the lot number and time corresponding to the count value from the alarm generation time to the recovery time in the device in which the alarm is generated are specified. In this case, the specified lot is not limited to one, for example, when the time from the alarm generation time to the recovery time is long,
To be many.

Next, as in the case of searching by lot number, the lot number and time for each specified apparatus are S160.
It is displayed on the display unit 1-4 together with the lot number and time read out in step 8 (S1510). In this case, when they are arranged in chronological order from the earliest time, the lots corresponding to the count value from the alarm generation time to the recovery time are displayed at the center. By doing so,
You can make it easier to see.

According to the production management apparatus of the present embodiment, the time and lot in each device corresponding to the alarm that has occurred can be specified from highly accurate trace information. When an alarm is issued in (1), the product corresponding to the alarm can be pursued by specifying the time and lot in the downstream device corresponding to the product processed during the alarm. In addition, by using the actual value of the minimum packing style, the lots processed by each device used in the filling and packaging process can be searched with the same conversion value, making it easy to identify the time and lot number for each device. You can

Although the invention made by the present inventor has been described in detail based on the embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say. For example, in the present embodiment, a case has been described in which the actual number of the minimum packing styles is obtained from the number of processed lots, but in each device, if the unit is the same, the number of processed lots may be searched. good.

EFFECT OF THE INVENTION In addition to the time information when the actual trace information is read out from the controller, the trace information such as the device name, the lot identification name, and the actual number of the smallest packaging in which the number of processed lots is converted into the minimum unit is stored. By doing so, the accuracy of the trace information can be improved. Further, the user can recognize the trace information of each device corresponding to the trace information of the designated device.

Since the time and lot in each device can be specified from the highly accurate trace information, for example, when a trouble occurs in the product in the downstream device, the product in the upstream device is processed. Since it is possible to specify the time and lot information, it becomes easy to pursue the raw material that caused the trouble. On the contrary, if a trouble occurs in the raw material in the upstream device, the time and lot processed by the device in the downstream device can be specified, so the product related to the trouble is pursued. Can be done easily.

Further, since the time and lot in each device corresponding to the alarm that has occurred can be specified from the highly accurate trace information, for example, when an alarm is generated in the upstream device, the alarm is being generated. By specifying the time and the lot in the downstream device corresponding to the processed product, the product corresponding to the alarm can be pursued.
