DETAILED DESCRIPTION OF THE INVENTION
In the present invention, quality data of a web (also called a mill roll) manufactured by a paper machine is detected before being taken up by a BM meter (Basis Weight & Moisture Measurement System) installed in the paper machine, input to a computer, and stored. When manufacturing a small roll from the roll (mill roll) in the next winder process, the computer extracts quality data corresponding to the small roll and calculates the quality of the small roll. An automatic determination method and apparatus for outputting a determination result to a winder process, and the present invention will be described in detail below based on examples. However, the present invention is not limited to this example.
[0013]
【Example】
FIG. 1 shows a flow relating to an automatic determination system for a winder finished product of the present invention. In FIG. 1, a web 3 manufactured by a paper machine 1 is wound up as a roll (mill roll) 4 by a reel part 2 of the paper machine, but before being wound up, a BM meter detection unit 5 detects the basis weight of the paper, Quality data such as moisture content and paper thickness is detected.
[0014]
The BM meter (Basis Weight & Moisture Measurement System) includes a BM meter detection unit 5 that is a detection unit and a BM meter control unit 6 that controls the paper machine by taking in the detection value of the BM meter detection unit. These data, which are taken in from the BM meter detection unit 5, are further transmitted from the BM meter control unit 6 to a computer that controls the winder and inputted. In the present invention, the computer that controls the winder is provided with a function for setting a winder processing method corresponding to each winding paper (mill roll) 4 wound by the paper machine, and data corresponding to the manufactured small winding paper. Since a search function is provided, a system using this computer is called a shunt system 7.
[0015]
In this embodiment, the BM meter detection unit 5 scans the web on which the paper machine is running from one end to the other end, and the basis weight of the paper every scan (one way about 30 seconds). The data transmission from the BM meter control unit 6 to the shunting system 7 is performed with respect to the basis weight of the paper, the moisture content of the paper, and the thickness of the paper. Data of 60 divisions with a full width is continuously transmitted for each scanning of the meter, and the splitting system 7 stores the transmitted BM meter data for each web 4 (mill roll). Here, as the data to be transmitted from the BM meter control unit 6 to the winding system 7, the types of data may be reduced, and for example, only two types of paper basis weight and paper moisture content may be implemented. Not what you want. In addition, when changing the frame of the paper machine (changing the product type and changing the winding dimension), the BM meter control unit 6 transmits the brand code, the mill roll winding length, the division dimension data in the mill roll winder, and the like.
[0016]
The wound paper (mill roll) 4 wound up by the paper machine is primarily stored in the storage location of the wound paper 4 and then sent to the winder process. In the winder process, the operator uses the mill roll NO attached to the winding paper 4 to collect data (brand name, etc.) corresponding to the winding paper 4 set on the winding stand (unreel stand) 11 of the winder 17. Select and take out from the input / output unit 13 of the winding system 7. By this selection, the brand code corresponding to the web 4, the web winding length, the division dimension data in the winder of the web is displayed on the screen of the input / output unit, and the slitting position of each slitter blade ( A slitting width signal is sent to the winding control unit 9 as a winding length signal. Next, the slitter device is automatically positioned by the operator's push button operation, and further, the operation is started by setting the operation speed and the winding start operation, and the small winding paper 8 having the specified width and the specified winding length is wound up.
In addition, although the division | segmentation dimension in the winder of a winding paper may be set at the time of winding up a winding paper in a paper machine as mentioned above, it determines in a winder process and may input from the input / output part 13 of the winding system 7. I can do it.
[0017]
The rolled up small web 8 is kicked out by the kick-out device 15, and at this time, the automatic quality judgment of the small web is performed by the splitting system 7. In this embodiment, the quality ranks to be judged are three ranks of non-defective items, suspended items, and waste paper, but this rank division may be classified into any number of ranks as long as it is two ranks or more, and is particularly limited. is not.
[0018]
The result of automatic quality judgment is displayed on the screen of the input / output unit 13 of the shunting system 7. If it is judged that the product is reserved or damaged paper, the damaged paper is red and the reserved product is yellow. An alarm device 14 is installed, and at the same time, an alarm sound is generated to prevent misidentification of the operator. The alarm device 14 may include both a patrol light and a device that emits an alarm sound as described above, but may include either one alone.
[0019]
The operator classifies the small web 8 according to the automatic quality determination result and sends it to the next process. If necessary, the profile data for each scan (basis weight of paper, 1-scan average value trend (paper basis weight, paper moisture value, paper thickness value) 1-scan fluctuation range trend (paper basis weight, paper thickness value) It is also possible to confirm the data such as the moisture value of the paper and the thickness of the paper) on the screen of the input / output unit of the splitting system 7 and make a determination again. In addition, the operator can take a hard copy of the judgment screen, profile screen, and trend screen from the input / output unit 13 of the shunt system 7 as necessary, and thus, it is judged as a suspended product or a damaged paper product. It is also possible to conduct a detailed investigation in some cases.
[0020]
The data group transferred from the BM meter control unit 6 to the dividing system 7 is stored in the dividing system 7 or the host computer 12 connected thereto until the automatic quality determination is completed. The data group after the completion is stored in the server (not shown) by the communication system 16 from the shunt system 7 through the host computer 12, and is searched by the computer for quality judgment data (not shown) as necessary. I can do it.
[0021]
When the web is classified by the automatic quality judgment, the operator inputs the quality judgment result from the host computer 12 and sends the data to the imprinting machine (not shown) and the labeler (not shown). After the data is displayed on the small roll paper 8, it is sent to the next process.
[0022]
Next, a method for automatic quality determination will be described in detail.

The case where there exist two, the range of H, and the range of LL-HH is shown. Further, FIG. 4 shows that the range of the allowable quality value set in advance with respect to the fluctuation range R of the basis weight of the paper which is the scan calculation value is 2 in the range of 0 to H and 0 to HH. This shows the case where there is one. Incidentally, although H and HH are used as symbols for the range of the average value A and the fluctuation range R, it goes without saying that they represent different numerical values.
[0026]
(4) Next, regarding the basis weight of the paper, the number of each of the average value A and the fluctuation range R, which are the scan calculation values, deviates from the preset allowable quality range is counted. Alternatively, the ratio of the number to the total number of scans is calculated. In the case of FIG. 3, the number of scan operation values (average value A of paper basis weight) deviating from the range of L to H is one, and the ratio (denoted as BWAH) of the number is 1/21. Further, the number out of the range of LL to HH is 0, and the ratio (BWAHH) of the number is 0. In the case of FIG. 4, the number of scan calculation values (paper basis weight fluctuation range R) deviates from the range of 0 to H is 1, and the ratio (BWRH) of the number is 1/21. The number out of the range of 0 to HH is 0, and the ratio (BWRHH) of the number is 0. BW is used as a symbol representing basis weight.
[0027]
(5) Next, regarding the moisture content of the paper corresponding to the small roll paper to be determined, the following values are calculated by performing the same operations as in the above (2) to (4). The following MP is used as a symbol representing the moisture content.

・ The ratio of the number of scan calculation values (variation width R of the moisture content of the paper R) outside the range of 0 to HH (MPRHH)
[0028]
(6) Next, regarding the thickness of the paper corresponding to the small roll paper to be determined, the following values are calculated by performing the same operations as in the above (2) to (4). The following CP is used as a symbol representing thickness.
The ratio of the number of scan calculations (average paper thickness A) outside the range of L to H (CPAH) The range of scan calculations (average thickness A of paper A) is LL to HH The ratio of the number deviating from the range ( CPAHH ) / scan calculated value (paper thickness fluctuation range R) is the ratio of the number deviating from the range of 0 to H ( CPRH ) / scan calculation value (paper thickness fluctuation range R) ) Is a ratio of the number outside the range of 0 to HH (CPRHH) In (2) to (6) of this embodiment, an example is shown in which calculation is performed in the order of the basis weight, moisture content, and thickness of the paper. The operation order is not limited.
[0029]
(7) Next, the quality rank of the small roll paper to be determined is determined according to the following predetermined quality rank determination criteria.
<Quality Judgment Criteria> ・ Scrap Paper Judgment …… If at least one of the following judgment formulas is satisfied, it is considered as a waste paper.
< 1 > Basis weight BWAHH (ratio) ≥ Loss paper judgment standard value (ratio) set in advance for BWAHH < 2 > Basis weight BWRHH (ratio) ≥ Scrap paper judgment standard set in advance for BWRHH Value (ratio) < 3 > Moisture percentage MPAHH (ratio) ≧ MPAHH preset waste paper judgment reference value (ratio) < 4 > Moisture percentage MPRHH (ratio) ≧ MPRHH preset preset relates broke criterion value (percentage) <5> thickness for CPAHH (ratio) ≧ CPAHH broke criterion value set in advance relates (ratio) <6> the thickness CPRHH (ratio) ≧ CPRHH Waste paper judgment standard value (ratio)
