Description

  The present invention relates to a production history management system, and more particularly to a production history management system for a production system that manufactures a product by sequentially processing articles in a plurality of production facilities.

Conventionally, a production system that manufactures products by sequentially processing articles in multiple production facilities has been used in the field of food and beverages. In this production system, the occurrence of defective products or abnormalities in production facilities should be specified. Therefore, a production history management system for managing production history for each production facility is provided.
As such a production history management system, a trace information collecting means for creating a database in which the number of articles processed by each production facility for each predetermined time is recorded for each production facility, and the database according to a specified search condition A production history management system including a lot trace processing means for performing a search is known (Patent Document 1).
In Patent Document 1, when an abnormality occurs in a predetermined production facility, the production facility where the abnormality occurred and the time range where the abnormality occurred are specified as search conditions in the lot trace processing means of the production history management system. Thus, a search was performed from the database, and it was detected in which time range the articles processed in the period in which the abnormality occurred were processed in other production facilities.
Specifically, the lot trace processing means detects the number of processed articles processed at the production facility where the abnormality occurred in the time range where the abnormality occurred as the actual number, and further adds the safety factor to the detected actual number. The count value was calculated.
Based on the calculated count value, the lot trace processing means detects in which time range the article processed in the production facility where the abnormality occurred is processed in the production facility located downstream thereof. .
JP 2003-337610 A (particularly columns 0052 to 0055)

However, in the case of Patent Document 1, the count value is calculated based on a safety factor determined for each production facility regardless of whether or not an abnormality has occurred. Therefore, if no abnormality has occurred in the production facility, There will be a difference between the number of processed articles actually processed and the count value.
In other words, the time range detected by the lot trace processing means may include articles that have nothing to do with the abnormality. It will end up collecting many items that are not available.
In view of such a problem, when a defective product occurs, the present invention shows in which time range an article that may have the same problem as the defective product was processed in another production facility. A production history management system capable of detecting with high accuracy is provided.

That is, the production history management system according to claim 1 is a production history management system of a production system that manufactures a product by sequentially processing articles in a plurality of production facilities,
The production history management system specifies a data acquisition unit that acquires, for each production facility, the cumulative number of articles processed by each production facility every predetermined time, and a data file created by the data acquisition unit. Search means for performing a search according to the specified search conditions,
The search means, when a production facility to be searched and a time range serving as a reference for the search are designated, an article processed within the designated time range in the designated production facility is processed in another production facility. In the production history management system that searches the time range,
The data acquisition means creates a data file that records, for each production facility, the cumulative number of non-defective items processed by each production facility and the cumulative number of rejected items rejected as defective by each production facility. And
The above search means determines that the total number of processed products, which is the sum of the number of non-defective products and the number of discharged products in the production facility located downstream, is the production facility adjacent to the designated production facility. It is characterized by searching a time range that includes the cumulative number of non-defective products.

According to the first aspect of the present invention, since the data acquisition means records the cumulative number of non-defective products and the cumulative number of discharges for each production facility, the production means to be searched for in the search means and the time range serving as a reference for the search , An article other than an article rejected as a defective product is not counted as a defective product.
Also, search for the time range in the adjacent production facility so that the cumulative number of non-defective products of the production equipment located downstream and the cumulative number of emissions includes the cumulative number of non-defective products of the production equipment located upstream. Since this is done, it is possible to accurately grasp the time range in which the article processed at the designated production facility is processed at the adjacent production facility.

The illustrated embodiment will be described below. FIG. 1 shows a bottling line 1 serving as a production system for producing a beverage product and a production history of the bottling line 1 by filling a container as an article from beverage filling to boxing. The production history management system 2 is shown.
The bottling line 1 includes a plurality of production facilities 3 such as an answerer 3A and a filler 3D described later, and each production facility 3 includes a control terminal 4 such as a programmable controller (PLC). The control terminal 4 controls each production facility 3.
The production history management system 2 is communicably connected to each control terminal 4 via a communication line 5 such as a LAN, and the number and occurrence of containers processed from the control terminal 4 every predetermined time or every occurrence of an event. A data acquisition unit 6 that collects various data such as abnormalities and creates a data file for each type of data, and a search unit 7 that searches a data file or data in a data file according to a specified search condition And an operation terminal 8 for displaying instructions to the search means 7 and search results.
According to this production history management system 2, a desired search is performed by the search means 7 from the data collected by the data acquisition means 6, so that the semi-finished products in the production system are processed in which time range in each production facility 3. Can be identified.

The bottling line 1 includes, in order from the upstream production facility 3, an anchor 3A for taking out an empty container packed in a case supplied from a depalletizer, a bottle washer 3B for washing the container, and an empty bottle for detecting cracks and chips in the container.

And the beverage product produced by this bottling line 1 is shipped to the customer by the pallet unit.
A predetermined production facility 3 of the bottling line 1 is provided with a material supply means 11 for supplying materials such as empty containers, caps, and labels.
In this embodiment, as the material supply means 11, a depalletizer 11A for supplying an empty container accommodated in a case in the answerer 3A, a cap supply means 11E for supplying a cap to the capper 3E, and a roll label on the labeler 3F. A label supply means 11F for supplying and a box supply means 11H for supplying an empty box to the cartner 3H are provided.
Further, the filler 3D in the bottling line 1 is provided with a preparation means 12 as a beverage supply means for preparing raw materials and supplying beverages to the filler 3D.
The bottling line 1 is provided with a printing means 13 between the labeler 3F and the appearance inspection machine 3G, and according to the setting of the date and time when the printing means 13 passed through the printing means 13 and the production lot number. Is printed. The printing means 13 is provided immediately after the labeler 3F, and when the passage date and time of the container is printed on time, the printed date and time can be regarded as the processing time of the labeler 3F.

Next, the control terminal 4 collects the following production-related data together with the processed time range, or is input by an operator.
First, as the number of non-defective products and the number of discharged products, the control terminal 4 automatically counts the number of containers that each production facility 3 supplies to the downstream production facility 3 as non-defective products and the number of containers that are rejected as defective products. The
Further, for each container rejected by each production facility 3, the date and content of the rejection are automatically saved by the control terminal 4 as the waste data, and the production facility having a number of processing heads such as a filler 3D and a capper 3E, for example. In the case of 3, the data of the head number that has processed the rejected container is also stored.
Furthermore, when an abnormality such as a machine stoppage occurs in the production equipment 3 as alarm data, the date and time of occurrence and the content of the abnormality are automatically saved by the control terminal 4, and for example, in the filler 3D, there is a lack of beverage or an abnormal liquid temperature In addition, the cap 3E may be short of caps.
As the actual value trace data, the state of each production facility at each predetermined time has been stored. For example, the control terminal 4D of the filler 3D constantly monitors the liquid temperature of the beverage in the filler tank in the filler 3D. Is saved.

In addition to this, when various types of production-related data are input to the control terminal 4 by an operator and the data is changed, the control terminal 4 stores the change contents and the change date and time.
First, in the control terminal 4 of the production facility 3 to which each material supply means 11 is connected, as material data, the material lot number of the material supplied from the material supply means 11, the use start date and time, the use end date and time of the material, Material manufacturer name and delivery date and time are stored.
In addition, in the control terminal 4D of the filler 3D to which the preparation means 12 is connected, the preparation lot number of the beverage supplied from the preparation means 12, the raw material input amount, the supply start date and time, the supply end date and time, etc., as preparation data In addition, the raw material lot number of the raw material used as the raw material of the beverage, the supply start date / time of the raw material, the supply end date / time, the manufacturer name of the raw material, the delivery date / time, and the like are stored as the raw material data.
These material data, preparation data, and raw material data may be automatically collected via the material supply means 11 and the preparation means 12.
Further, various set values necessary for each production facility 3 are stored as facility set value data. For example, in the case of the filler 3D, the filling amount of the beverage for each container is stored. In the capper 3E, the capping torque to the cap is stored. Is saved.
And as inspection data, the inspection result which the worker performed about the product extracted from each production equipment 3 during operation of the bottling line 1 is stored. For example, in the filler 3D, the inspection result of the filling amount into the container is stored. In 3E, the capping torque is stored as an inspection result.
Further, as the exception processing data, data when a predetermined container is processed differently from other containers is stored. For example, the filling amount of the beverage is changed with the filler 3D, or the capping torque is changed with the capper 3E. Or data such as when each production facility 3 is manually operated is stored.
In addition to this, the name of the worker in charge of each production facility 3 as worker data, the contents of modification or remodeling applied to the production facility 3 as work data, the temperature in the factory and power outages as environmental data The presence / absence of each is stored.
Data that can be input by these workers may be directly input to the production history management system 2.
And the production lot number is defined in advance for the beverage product to be produced, and this production lot number is registered in each control terminal 4 via the production history management system 2, and when the type of product to be produced is changed, The production lot number is changed.

The operation of the bottling line 1 having such a configuration will be described below. The preparation means 12 prepares a beverage in advance and supplies it to the filler 3D according to the beverage product to be produced. Are supplied to each material supply means 11 and data such as a production lot number and a preparation lot number are input to the control terminal 4 of each production facility 3.
When the bottling line 1 is operated from this state, the depalletizer 11A takes out the case from the pallet and supplies it to the anchor 3A, and the anchor 3A takes out an empty container from this case and supplies it to the bottle washer 3B. .
Thereafter, the container cleaned by the bottle washing machine 3B is supplied to the empty bottle inspection machine 3C, where the container is inspected for scratches and cracks. When the empty bottle inspection machine 3C detects a crack or a flaw in the container, the container is rejected as a defective product, and the rejection data is stored in the control terminal 4C.

Next, the container supplied from the empty bottle inspector 3C to the filler 3D is filled with a beverage in the filler 3D. If, for example, a filling failure occurs in the filler 3D, the container is rejected as a defective product, and the detection result At the same time, the number of the filling nozzle in which the filling failure has occurred is stored in the control terminal 4D as exclusion data.
In the filler 3D, for example, when an abnormality occurs in the liquid temperature of the beverage, the content of the abnormality is stored in the control terminal 4D as alarm data.
In addition, the quality check result of the beverage prepared by the preparation means 12 is input to the control terminal 4 of the filler 3D by the operator as inspection data together with the time when the beverage used for the quality check is extracted.

The container filled with the beverage by the filler 3D is capped by the capper 3E, and when the winding failure or the like occurs in the capper 3E, the container is rejected as a defective product, and the number of the capping head in which the winding failure has occurred along with the detection result. Is stored in the control terminal 4 as exclusion data.
Next, the capped container is labeled by the labeler 3F. When a labeling failure or the like occurs in the labeler 3F, the container is rejected as a defective product, and the rejection data is stored in the control terminal 4.
The date and time when the container passes through the printing unit 13 and the production lot number are printed on the container supplied from the labeler 3F to the appearance inspection machine 3G by the printing unit 13 provided in the middle of the container.

Further, when the container is transported to the appearance inspection machine 3G, the appearance inspection machine 3G performs an inspection using an optical sensor or the like on the container. Is detected as a defective product, the rejection data is stored in the control terminal 4.
A plurality of containers supplied to the cartner 3H are stored together in a box, and if the box assembly failure or container storage abnormality occurs in the cartner 3H, the container is rejected as a defective product, and the waste data is transferred to the control terminal. 4 is stored.
When the boxes containing the containers are conveyed to the palletizer 3I, the palletizer 3I sequentially stacks the boxes in a predetermined pattern on the pallet, and when a predetermined number of boxes are placed on the pallet, the pallet is moved to a new pallet. It is supposed to be replaced.
In addition, the control terminal 4 of the palletizer 3I obtains the number of non-defective products by adding the number of boxes to the number of containers stored in the box, and the pallet of the pallet on which a predetermined number of boxes are placed and replaced. The quantity is counted, and the pallet number of the pallet is recorded as the shipping data as the final shipping unit number.
The control terminal 4 of each production facility 3 from the answerer 3A to the palletizer 3I counts the number of non-defective products and the number of discharges each time the production facility 3 processes the container, and stores the data.
For the terminal device 4 of the manufacturing facility 3 that does not discharge containers, such as the answerer 3A and the palletizer 3I, the number of discharges may be set to 0 in advance and the number of discharges may not be counted.

Next, the production history management system 2 will be described. The data acquisition means 6 collects various data such as the cumulative number of non-defective products and the cumulative number of discharges every predetermined time from the control terminal 4 of each production facility 3. Are recorded and saved in a data file in time series.
For example, the data acquisition unit 6 collects the cumulative number of non-defective products and the cumulative number of discharged containers processed by each production facility 3 for each predetermined time from the start of the work to the end of the work, and records and stores it in a data file.
In addition to the cumulative number of non-defective products and the cumulative number of emissions, the data acquisition means 6 includes waste data, alarm data, actual value trace data, material data, preparation data, raw material data, equipment set value data, inspection for each production facility 3 Collect various production-related data such as data and exception handling data, and organize and store them in each data file in time series.
Next, the search means 7 performs a search from the data file created by the data acquisition means 6 according to the search conditions input by the operator to the operation terminal 8.
The operation terminal 8 can be a conventionally known personal computer or the like, and includes a monitor for displaying a screen to be described later, a keyboard and a mouse for inputting search conditions and the like.

Hereinafter, the production history search procedure by the production history management system 2 will be described with reference to actual examples.
Here, it is assumed that a defective product of a shipped beverage product is found and a production history is searched for the purpose of identifying the cause of the defect. It is assumed that a defective container is printed by the printing means 13 as the date of manufacture, for example, “March 27, 2003, 15:22”.
When the production history management system 2 is started from the above conditions, the “main menu” screen shown in FIG. 2 is first displayed on the operation terminal 8, and two types of search methods are roughly selected on the “main menu” screen. Can do.
“Select from process diagram” at the top of the “Main Menu” screen is used to search the production history from the manufacturing date and time printed on the beverage product, and “Tracking from each element” at the bottom is found to be abnormal Used when the production lot number of the beverage product or the material lot number supplied to the material supply means 11 is known.
In the case of the present embodiment, since the production lot number and the material lot number are unknown under the above conditions, the operator selects “March 27, 2003” from the calendar displayed in the “Select from process diagram” column. Then, the user designates the “to production result process chart” button 21 displayed below the calendar.

By instructing the “to production result process chart” button 21, the search means 7 searches the data file recorded by the data acquisition means 6 for necessary data for the work content of “March 27, 2003” The “production result process chart” of FIG. 3 is displayed on the operation terminal 8.
This “production performance schedule” includes the production lot number of the beverage product produced on the bottling line 1 on “March 27, 2003”, and the materials of the materials supplied to each production facility 3 from each material supply means 11. The lot number and the beverage lot number of the beverage supplied from the preparation means 12 to the filler 3D are displayed as a time-series table for each hour.
In the case of this example, since “March 27, 2003, 15:22” was printed on the container, it can be seen from this “production result process chart” that the manufacturing lot number of the container was “1000A1”. . (A in the figure)

When the part indicated by the production lot number “1000A1” is designated, the search means 7 searches the data file for the time range in the filler 3D where the beverage product with the production lot number “1000A1” was manufactured, and the time range. The production history of the entire bottling line 1 is retrieved and the “traceability” screen of FIG. 4 is displayed on the operation terminal 8.
That is, here, the search is performed under the condition of the time range in which the production facility to be searched is the filler 3D and the manufacturing lot number “1000A1” is processed in the filler 3D as the search reference time range.
In the upper part of the “traceability” screen, the lot start date and time when the process is started in the filler 3D for the production lot number “1000A1” and the lot end date and time when the process is completed are displayed.
In the lower part, the cumulative number of non-defective products and the cumulative number of discharged products in each production facility 3 constituting the bottling line 1 are displayed every time when the time displayed in the left column elapses. Beverage products related to the production lot number “1000A1” The columns of the number of non-defective products and the number of accumulated discharges corresponding to are all displayed in a discolored state.
Here, the search results are distinguished by discoloring the columns, but may be distinguished by other methods such as shading or bolding.
Depending on the monitor of the terminal device 8, since the time range “15:00” to “18:00” of the production lot number “1000A1” cannot be displayed at a time as shown in FIG. Although the discolored portion and the undiscolored portion are not displayed, by scrolling up and down the table and browsing the entire time range, it is possible to distinguish the portion not related to the production lot number “1000A1”. It is possible.
In addition, in the upper part of FIG. 4, a selection field 42 for changing the time interval displayed on the “traceability” screen is displayed, and an arbitrary interval such as 5 minutes, 10 minutes, 1 hour, etc. is designated. Thus, the search means 7 can display the cumulative number of non-defective products and the cumulative number of discharges for each interval.
In this embodiment, the processing time corresponding to the manufacturing lot number is set to be the same as the processing time in the filler 3D. Therefore, when the production lot number is specified and searched as described above, “Fila” is displayed in the “Trace Target Model” column in the “Traceability” screen of FIG. 4, and the time corresponding to the designated production lot number is displayed. As a range, a time range for the filler 3D is searched.

When the “traceability” screen of FIG. 4 is displayed and the user wishes to further narrow down the time range by performing a search, the operator instructs the “search” button 41 at the top of the table, and the operation terminal accordingly. 8 displays the “search condition instruction screen” of FIG.
In this search condition instruction screen, the production equipment 3 to be searched and the time range as a reference for the search are specified. Here, the designated production is specified in the “Trace Target” column 51 of the “Search Condition Instruction Screen”. “Labera” is selected as the equipment, and “search date and time” field 52 is entered with “specified date range” as “March 27, 2003 15:20” and “2003 March 27, 15:25”.
Here, the reason why the labeler is selected as the designated production facility is that the time printed on the container by the printing means 13 substantially coincides with the time processed by the labeler 3F. Is changed, the production facility 3 adjacent to the printing means 13 may be designated as the designated production facility.
Moreover, although the interval of 5 minutes is taken centering on "15:22" printed on the container as the said designated time range, this interval can be set long or short.
If the control unit 4 is connected to the printing unit 13 and the quantity of containers printed is recorded in the data file by the data acquisition unit 6, the time when printing by the printing unit 13 is displayed on the "traceability" screen of FIG. The printing means 13 can be specified in the “Trace Target” column 51.

When the designated production facility and the designated time range are entered in the “Trace Target” field 51 and the “Search Date / Time” field 52 respectively in the “Search Condition Instruction Screen” of FIG. 5 and the “Search” button 53 is designated, the search means 7 The “traceability” screen shown in FIG. 6 is displayed again according to the procedure described below.
In FIG. 6, the color is displayed in a discolored manner narrowed down by the search condition input in the “search condition instruction screen”. It should be noted that, including this figure, the columns that are displayed in the following color are displayed by hatching the outer columns instead of displaying the corresponding column in a discolored state.
The discoloration display portion will be described. First, the search means 7 displays a column for the number of accumulated non-defective products and the number of accumulated emissions corresponding to the designated time range “15:20” to “15:25” for the designated production facility “Labera”. Search and change these columns. (B in the figure)
Next, the search means 7 adds the cumulative number of non-defective products (640) and the cumulative discharge number (30) at “15:20” in the labeler 3F to obtain the cumulative processing number (670), which is accumulated in the capper 3E. Compare with the number of good products.
As a result, when it is recognized that the cumulative processing number (670) in the labeler 3F is between the cumulative number of non-defective items (652) and the cumulative number of non-defective items (705) in the capper 3E, the search means 7 accumulates in the labeler 3F. It is determined that the processing number (670) is included in the cumulative number of non-defective products (652) in the capper 3E.

In the same manner, the search means 7 adds the cumulative discharge number (35) to the cumulative number of non-defective products (895) at “15:25” in the labeler 3F to obtain the cumulative processing number (930), which is obtained by the capper 3E. Compared with the cumulative number of non-defective products, it is determined that it is included in the cumulative number of non-defective products (970) in the capper 3E.
In the capper 3E, the search means 7 calculates the cumulative number of non-defective products and the cumulative number of discharged products from “15:19” where the cumulative number of non-defective products is (652) to “15:25” where the cumulative number of non-defective products is (970). Change the color of the column.
Further, the search means 7 performs the above processing also between the capper 3E and the filler 3D corresponding to the upstream production facility, and performs this in the columns of the number of non-defective products and the number of accumulated discharges of the anchor 3A located on the most upstream side. Repeat until the color changes.
As a result, the container processed from “15:20” to “15:25” by the labeler 3F is processed from “15:19” to “15:25” by the capper 3E, and “15:11” by the answerer 3A. It can be understood that it was processed at “15:23”.

In parallel with this, the search means 7 also performs a search between the labeler 3F and the appearance inspection machine 3G corresponding to the downstream production facility, and in this case as well, the cumulative processing number of the downstream production facility is the upstream side. A search is performed under conditions that are included in the cumulative number of non-defective products in the production facility.
Specifically, the search means 7 uses the number of accumulated processing in the appearance inspection machine 3G as included in the number of accumulated non-defective products (640) to (895) from “15:20” to “15:25” in the labeler 3F. Search for.
That is, the search means 7 indicates that the cumulative processing number (632 + 8 = 640) to (892 + 8 = 900) in the appearance inspection machine 3G includes the cumulative number of good products (640) to (895) of the labeler 3F. Detected, the columns of “15:21” to “15:26” for the number of non-defective products and the number of accumulated discharges so that the number of non-defective products of the appearance inspection machine 3G is (632) to (892) are discolored.
The search means 7 repeats this process until the column of the palletizer 3I located on the most downstream side is changed in color. In the present embodiment, the accumulated discharge number data in the palletizer 3I is always set to “0”.
At this time, the column for the palletizer 3I has “number”, “C / S”, and “P / L”. “What is the number” indicates the number of boxes transported from the cartner 3H and the beverage product in the box. “C / S” is the number of boxes processed by the palletizer 3I, and “P / L” indicates the number of pallets processed by the palletizer 3I.
As a result, the container processed from “15:20” to “15:25” by the labeler 3F is processed from “15:21” to “15:26” by the visual inspection machine 3G, and “15: 22 ”to“ 15:32 ”, and it can be understood that the pallet number 3I is placed on the pallets with the pallet numbers“ 1 ”to“ 3 ”.

In this way, as a result of the search by the search means 7, it is determined in which time range the containers processed from “15:20” to “15:25” by the labeler 3F were processed in the other production facilities 3. Know exactly.
That is, in the present embodiment, the data acquisition means 6 records the cumulative number of non-defective products and the cumulative number of discharges every predetermined time, and calculates the cumulative processing number by adding the cumulative number of non-defective products and the cumulative number of discharges. It is possible to accurately know in which time range the articles processed in the specified time range in the specified production facility are processed in the other production facilities 3.
On the other hand, in the conventional patent document 1, since the safety factor was set for each production facility and the safety factor was integrated into the number of processes, the number of emissions increased uniformly even if the defective product was not actually rejected. We could not say that we were searching for the exact number of processes.

Furthermore, for example, if there is a liquid leak from the container and the cap as a defective product, if the cause of the liquid leakage is considered to be a cap molding failure or poor accuracy, the information on the cap as a material product is used. Try to narrow the range.
In the state where the “traceability” screen of FIG. 6 is displayed, when the operator designates the “trace information” button 61 at the top of the table, the “selection screen” of FIG. The “information” button 71 is selected.
Then, the search means 7 has already searched in which time range the containers processed from “15:20” to “15:25” in the labeler 3F were processed in the other production facilities 3, and By detecting the lot number of various materials supplied to the material supply means 11 in the time range, the “material lot information screen” of FIG. 8 is displayed.
Specifically, the retrieval means 7 is that the container processed from “15:20” to “15:25” in the labeler 3F is processed from “15:19” to “15:25” in the capper 3E. And the material lot number of the cap supplied from the cap supply means 11E to the capper 3E within this time range is detected.
As a result, it was found that the container with the material lot number “AAAA2” was used in the container processed from “15:20” to “15:25” with the labeler 3F (C in the figure). It is also possible to know the time range from the start of supply of the cap from the cap supply means 11E to the end of supply, and the manufacturer code indicating the manufacturer of the material.

In addition, when it can be determined in advance that there is a problem with the cap, which is a material product, as a defective product, it is possible to pursue from the information on the cap. In that case, the operator displays the main menu of FIG. 2 and designates the “material lot” button 23 of “tracking from each element”, whereby the search means 7 displays the “material lot selection screen” of FIG. To do.
Below this “material lot selection screen”, a list of materials supplied to the bottling line 1 on “March 27, 2003” is displayed, together with the supply start date and time, supply end date and time, manufacturer code, etc. Data is displayed.
Then, when the worker designates the material lot number “AAAAA2” of the cap from this table, information on the material lot number is displayed in the “selected lot” column 91 at the top of the screen, and then the “Lot selection decision” button is further displayed. 92 is indicated.

Then, the search means 7 displays the “traceability” screen shown in FIG. This “traceability” screen has the same contents as those shown in FIGS. 4 and 6, but the range displayed by the search means 7 is different.
Specifically, since the target material is a cap, the capper 3E is designated as the designated production facility, and the cap of the material lot number “AAAAA2” is supplied to the capper 3E “15: By setting the designated time range from “15” to “15:30”, the search means 7 changes the color of the number of accumulated non-defective products and accumulated number of discharges corresponding to the designated time range. (D in the figure)
That is, here, the search is performed under the condition of the capper 3E as the production facility to be searched and the time range of the search reference from “15:15 on March 27, 2003” to “15:30 on March 27, 2003”. ing.
Then, as described in the “traceability” screen of FIG. 6, the search means 7 changes the color of the cumulative number of non-defective products and the cumulative number of discharges for each of the upstream production facility and the downstream production facility of the capper 3E.
For example, in the case of the filler 3D that is the upstream production facility of the capper 3E, the cumulative number of processes in the capper 3E from “15:15” to “15:30” is (440 + 12 = 452) to (1235 + 21 = 1256), Since the number of accumulated non-defective products of the filler 3D including this accumulated processing number is (425) to (1307), the containers with the cap of the material lot number “AAAAA2” are “15:14” to “15:32”. During this time, it was found that the film was processed by the filler 3D.

In order to further seek the cause of the liquid leakage, if the discolored column of the number of accumulated good products or the number of accumulated discharges of the capper 3E is designated, the retrieval means 7 displays the “related information” screen of FIG.
In the “related information” screen, various information collected for the capper 3E in the time range in which the cap of the material lot number “AAAA2” is processed is shown.
Specifically, production-related data such as the production lot number of the beverage product in the designated time range, the preparation lot number of the beverage filled at that time, and the material lot number of the cap supplied to the cap supply means 11E are stored. Is displayed.
Further, on the right side of this screen, buttons of “inspection data”, “exclusion data”, and “alarm data” are displayed. For example, when the operator designates the “exclusion data” button 111, the search means 7 displays FIG. 12 “capper evacuation data” screen is displayed.

This “capper evacuation data” screen displays a list of containers rejected by the capper 3E between “15:15” and “15:30” when the cap of the material lot number “AAAA2” is supplied. It is supposed to be.
Further, on this “capper evacuation data” screen, the evacuation data recorded in the data file of the data acquisition means 6 is displayed, the cumulative number of processes in the capper 3E at the time of rejection, and the capping that capped the container The head number is displayed.
As shown in this table, if it is clear that the rejected container has been processed by the capping head number 5, the cap is not abnormal, and there is a cause of liquid leakage in the capping head 5. It can also be judged that.
In addition, if the “inspection data” button 112 is pointed out among the buttons of the “related information” screen in FIG. 11 described above, the search means 7 is performed between “15:15” and “15:30” with the capper 3E. When the inspection results are displayed in time series and the “alarm data” button 113 is pressed, the retrieval means 7 displays the contents of the alarm generated between “15:15” and “15:30” by the capper 3E in time series. Is displayed.
In addition, when the discolored column of the other production equipment 3 is designated on the “traceability” screen of FIG. 10, the “related information” screen in the designated time range in the production facility 3 is displayed in the same manner as the column of the capper 3E. Furthermore, when each button of inspection data, exclusion data, and alarm data is instructed, various production-related data in the designated time range in the production facility 3 are displayed in time series.
In the “related information” screen of FIG. 11, only the buttons for inspection data, exclusion data, and alarm data are displayed, but other productions such as actual value trace data, facility setting value data, exception processing data, and work data are displayed. You may make it search by providing the button of related data.

On the other hand, if it is found that there is a cause for the defect in the cap of the material lot number “AAAAA2” and it is determined that the beverage product is to be collected, on which pallet the beverage product in which the cap is used is loaded. It is necessary to specify whether it was attached and distributed to the market.
In this case, in the state where the “traceability” screen shown in FIG. 10 showing the search result related to the cap of the material lot number “AAAA2” is displayed, the “trace information” button 101 at the upper part of this figure is instructed. 7 “selection screen” is displayed.
Here, when the operator selects the “shipment information” button 72, the search means 7 searches the pallet on which the beverage product with the cap of the material lot number “AAAAA2” is loaded. Display the "shipping information" screen.
Here, if the beverage product with the cap of the material lot number “AAAA2” is stored in one box among the boxes stacked on the pallet by the palletizer 3I, the search means 7 detects the pallet. It is supposed to be displayed as.
As a result, it was found that the beverage product with the cap of the material lot number “AAAA2” was loaded on the pallets with the pallet numbers “1” to “3”. And “end date and time of loading” are also found.
Then, if an arbitrary pallet number displayed here is designated, the search means 7 detects shipping data such as the date and time when the pallet was shipped and the supplier name of the shipping destination, and displays this on the operation terminal 8. The worker can contact a business partner or the like from the display result.

In the above-described embodiment, the production history of the bottling line 1 is searched. However, a production system including a plurality of other production facilities 3 may be used, and the contents and search of the table displayed on the operation terminal 8 may be used. The order in which they are performed is not limited to this.
Further, the position at which the printing unit 13 is installed is not particularly limited, and if the printing unit 13 prints the production lot number in addition to the production date and time, the production lot number can be quickly obtained. It is possible to search for defects and the like.
