Concerning indirect measurement methods.

方法を要約すると次のとおりである。[Prior art] In recent years, a transfer roll coater has been placed in the middle of the dryer group of a paper machine, and this is where surface size liquid and paint are applied. There is a need for more sophisticated measurement technology. A method for online measurement of coating amount using a transfer roll coater having a metering roll such as a gate roll coater is summarized as follows.

乱になる欠陥がある。 Measured from the amount of paint consumed over a certain period of time. This method allows measurements to be made at certain intervals in a relatively short period of time, such as 5 or 10 minutes, but the accuracy is extremely low, and the coating amount on each side and the coating amount profile in the width direction is completely unknown. It is possible to increase the accuracy of the paint consumption rate by installing a measuring tank and measuring the actual weight with a load cell, etc., but in order to know the amount of paint applied on each side, it is necessary to check the supply and return system. must be installed completely separately. Also, during this measurement time, the paint supply and return systems are closed, so if you try to increase the accuracy by lengthening the measurement time, the physical properties of the paint will change, causing a defect that may cause operational disturbances.

出来ない。 Measured from the difference between the base paper weight and the coated paper weight.
In this method, changes in the basis weight (absolute dry weight) of the web before and after coating are measured using, for example, a basis weight meter. The amount of coating on the front and back sides of the web is unknown.
Furthermore, in the case of clear coat, it is not possible to measure the amount applied.

および品質面で大きな問題となる。[Problems to be solved by the invention] In order to measure the amount of paint applied on each side based on the amount of paint consumed, it is necessary to separate the supply systems for the paint on the front and back sides and measure the consumption of each. Although it is not impossible, it would be complicated in terms of equipment, and it would be extremely expensive compared to a single system. Moreover, it is impossible to detect the profile of the coating amount in the width direction using the method based on the amount of paint consumed, and if the coating amount is uneven in the width direction, it will pose a big problem in terms of operation and quality.

塗布量を測定できても、表、裏それぞれの塗布量
を測定することは出来ない。 Transfer roll coaters often coat the front and back of the sheet at the same time. Although the method described above can measure the total coating amount, it is not possible to measure the coating amount on each of the front and back sides.

行なうことを目的としている。 Therefore, the present invention does not measure the coating amount by detecting the change in the basis weight of the web before and after coating, as is the case with grammeters, but instead uses a non-contact method to measure the moisture content in the paint layer formed on the applicator roll. The purpose of this detection is to accurately measure the coating amount on each side of the web online.

量を測定できる。 Two concentrations of paint, 50% and 55%, were prepared, and Maya bars (numbers used: #0, #4, #5, #) were placed on a rubber plate of the same quality as the applicator roll.
8. Apply each paint using #10, #14, #16), measure the readings before and after application with a detector (infrared moisture meter), and at the same time measure the amount of wet paint applied at that time and measure it with an infrared moisture meter. When we determined the correlation between the absorption rate and the actual water content, we confirmed that there was a linear relationship as shown in Figure 2. Also, the concentration is 50%
When the relationship between the coating amount (absolute dry coating amount) and the absorption rate of an infrared moisture meter was determined for each of 55% and 55% coating, the results shown in FIGS. 3 and 4 were obtained. As can be seen from Figure 2, there is a very high correlation between the amount of moisture converted per m 2 and the fluctuation of the infrared moisture meter. The correlation coefficient is 0.99, and the correlation with the coating amount calculated from this is also the same, so it can be fully used for measuring the coating amount. Furthermore, as is clear from FIGS. 3 and 4, even if the paint concentration changes, the relationship between the amount of moisture per m 2 and the value indicated by the infrared moisture meter remains constant. Therefore, by obtaining a calibration curve between the moisture meter reading and the moisture content per m 2 , the coating amount can be measured from the paint concentration at that time.

水分率よりウエブ塗布量を測定できる。 The paint supplied from the coating liquid feeders 5a and 5b is stored above the inner roll and outer roll that form the gate roll, and the amount of paint supplied is regulated by the clearance between both rolls, and the peripheral speed of the inner roll and applicator roll is controlled. The coating amount is thus determined. Part of the paint layer formed on the applicator rolls 2a, 2b is transferred to the web at the nip formed by the applicator rolls, and part of the paint layer is not transferred and contacts the respective inner rolls 3a, 3b again, forming a new paint layer. is formed on the applicator roll. Therefore, if the amount of water contained in the paint before and after the transfer of the paint layer on the applicator roll is measured by each detector 6, 7, 8, and 9, the amount of water applied to the web can be determined from the difference and the water content in the paint. Can be measured.

ものである。 The illustrated example uses a two-color infrared moisture meter as a detector for the top and bottom applicator rolls 2a and 2b.
A total of four units were installed, one each before and after application, to detect the moisture content of the paint layer on the front and back sides, and measure the amount of each web coated by determining the difference in moisture content before and after application. Post-transfer detection is not necessary if the rate of paint transfer from the roll to the web is constant. Furthermore, when it is acceptable to detect only one of the front and back sides of the web, the other detector can be omitted. In any of the above cases, the coating amount profile in the width direction can also be measured by scanning each detector in the width direction. Normally, the peripheral speed of the applicator roll is kept constant, and if the measurement result is less than a predetermined application amount, the peripheral speed of the inner rolls 3a and 3b is increased, and if the application amount is more than the set value, the inner roll It operates by reducing the circumferential speed and applying paint within a set range.

A back-up roll 10 is placed between the two. Further, a detector 6 is provided above the applicator roll 2 to measure the moisture content of the paint layer before application.

い。Kaolin (US clay) 100 parts Dispersant 0.2 parts NaOH 0.2 parts SBR latex 15 parts Oxidized starch 5 parts Paint concentration 55% Type B viscosity 1.300 cp The paint with the above composition was supplied onto the gate roll from the paint feeder 5, and the coating speed ( The coating was applied onto the base paper 1 at an applicator roll speed of 300 m/min (constant) and controlling the peripheral speed ratio of the inner roll to the applicator roll in the range of 30 to 95%. The moisture on the applicator roll was measured in infrared absorption rate (%) using an infrared moisture meter (detector), and at the same time it was applied to a web (55 g/m 2 medium base paper), and the amount of coating at that time was measured. I got the graph in figure.
As is clear from this, it was recognized that there was a high correlation between the reading of the infrared moisture meter installed on the actual applicator roll and the amount of coating applied to the base paper at that time. In this case, only the moisture content of the paint layer on the applicator roll before application is detected, so the amount of moisture on the applicator roll after the paint has been transferred to the paper is not measured, but other conditions such as the base paper are constant. If so, highly accurate test results can be obtained without using a method of detecting and subtracting the moisture content of the paint layer on the applicator roll after application. However, in the case of actual machine operation, there are more disturbances than in tests, so it is preferable to measure the coating amount from the moisture content before and after coating.

理することが出来る。(1) Provide a new method for measuring web coating amount.
The amount of coating transferred to the web is measured by measuring the amount of water per unit area of the paint layer on the applicator roll. The amount of paint applied and its distribution can be controlled regardless of the weight distribution of the web itself.

なかつた。(2) The effect of the present invention is remarkable when the paint is applied to the front and back sides of the web simultaneously or close to each other.
This is because it is possible to measure the coating amount and its distribution on each of the front and back surfaces. Conventional transfer roll coaters do not have such means for controlling the amount of coating separately for the front and back sides.

The amount of application can be measured. In the conventional method, since the absolute dry weight of the web after coating is measured, there is little change in weight before and after coating, making measurement difficult. In the present invention, since the water content of the paint layer on the applicator roll before application is targeted, it is also easy to manage the amount of clear coat applied.
