20145197 prh 14-06-2018

Area

The invention relates to a corrugated board control and manufacturing apparatus and a control and manufacturing method.

Background

Corrugated board is widely used as packaging material, for example in transport packaging, consumer packaging and wrapping. The corrugated board has at least one fluting sheet and at least one straight liner (liner). Often one corrugated paper is glued between two liners. The corrugated board may have a plurality of corrugated layers to improve strength and durability. Usually starch glue is used as the adhesive, but wet conditions may also be used for wet conditions.

It is important for the quality of the corrugated board that the adhesives are solid and the surfaces of the boards are undistorted. There are deficiencies in the control of corrugated board production, which impairs the quality of corrugated board. Therefore, there is a need to improve the production of corrugated board.

Description of Embodiments

The following embodiments are exemplary. Although the description may refer to one, one or some embodiment or embodiments at different points, this does not necessarily mean that each such reference is to the same embodiment or embodiments, or that the feature applies to only one embodiment. The individual features of the various embodiments may also be combined to enable other embodiments.

20145197 prh 14-06-2018

Figure 1 shows an example of a corrugated cardboard manufacturing apparatus. At the start of the process, there is at least one splicer 10, in which the paper rolls 12 are unwound and fed forward towards the corrugator and gluing. The width of the paper is usually about 2.5 m. To make corrugated paper, the paper is corrugated with a corrugator 14 (singlelacer), in which the liner is also glued to the corrugated paper. This produces a single-sided corrugated board. In adhesive station 16B (glue machine), one liner of corrugated cardboard is glued to form a single or multiple waveguide and at least a two-liner corrugated board. The one or more subwoofers and at least two-liner aal10 top coffee are then heated with a grate 18 to dry the adhesive. Correspondingly, multilayer corrugated board can also be formed. When one paper roll 12 is empty, a new paper roll 12 can be used, whereby the end of the remaining paper can be glued to the end of the starting paper. Because the corrugated board machine produces different sized batches of corrugated board, the roll of paper may change e.g.

Every 15 minutes. For the production of single or multiple waves and at least two-ply corrugated paper, three rolls of paper are required, which further increases the paper roll rotation in the manufacture of corrugated board.

Several corrugated profiles can be made on corrugated corrugated paper. With G&N microwave paper, the corrugated cardboard has a thickness of about 0.8 mm and a wave number of about 550 waves per meter. For microwave F paper, the corrugated board has a thickness of about 1.0 mm and a wave number of about 440 waves per meter. For Miniature E-Paper, corrugated board has a thickness of about 1.5 mm and a wave number of about 300 waves per meter. For fine B paper, the corrugated board has a thickness of about 3 mm and a wave number of about 150 waves per meter. For coarse-wave C paper, the corrugated board has a thickness of about 4 mm and a wave number of about 130 waves per meter. On two-wave BC paper, the corrugated board has a thickness of about 7 mm.

Corrugating paper can be made from virgin fiber, for example in a semi-chemical process, and can have a basis weight of 80 g / m ² to 200 g / m ² . On the other hand, Recycled Fluting (RF) can also be made partially or wholly from recycled fibers. For example, corrugated board can use three types of liners: kraftliner, euroliner and test liner. Kraftliners are mainly made from virgin fiber and kraftliners are suitable for food packaging. The basis weight can

20145197 prh 14-06-2018 range from 60 g / m ² to 400 g / m ² or even above 400 g / m ² . Eurolayers are made of recycled paper. Testliners are mainly made from recycled fiber. When making corrugated board, instead of papers, one can also talk about paperboard, i.e.. corrugated board and surface board.

The quality and properties of the paper used will affect the quality of the end-made corrugated board. Often, paper rolls are stored in an outdoor storage room where the temperature and the one or more waves and at least two-liner are constantly changing. For this reason, the humidity and temperature of the paper in the rolls of paper vary with the weather and therefore differ from the paper machine's operation. In addition, the moisture and temperature of the paper also depends on whether the moisture and temperature of the paper is viewed from the outer periphery, inner periphery, edge or center of the roll. Particularly as the roll changes, the single or multiple wave and at least two wave lines can change a lot suddenly. Temperatures can also change drastically. Such moisture changes cause deformation (warb, curl) of the paper and the finished corrugated board, which adversely affects the production of the corrugated board and the folding and assembly of the corrugated board. Temperature can likewise influence the distortion of the corrugated board.

Figures 2 and 3 illustrate a corrugated board manufacturing apparatus for producing single or multiple waves and at least two-ply corrugated board. The apparatus of Figure 2 is associated with a sizing station 16B. The corrugated board production control apparatus comprises a sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G and a moisture-actuating actuator 104A, 104B, 104C, 106A, 106B. Further, in one embodiment, the corrugated board manufacturing apparatus may comprise a guide

130 and user interface 132. Controller 130 may comprise at least one processor and one or more memories having computer program code. By means of said at least one processor and said one or more memories, the computer program code may cause the corrugated board control and / or manufacturing equipment to function as desired.

The sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G measures the surface moisture from at least one liner 144, 148.

20145197 prh 14-06-2018

The humidity actuator 104A, 104B, 104C, 106A, 106B, 106C, 106D adjusts the surface humidity of at least one liner 144, 148 based on the measurement of the sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G.

Figure 3 illustrates an apparatus for producing single-sided corrugated board 5 for the manufacture of single or multiple waveguide and at least double-wavy corrugated board of Figure 2.

Shape distortion can be measured, for example, by an imaging device such as a camera and a laser. The laser can then form a corrugated liner 144,

1 48, 150 onto a known pattern. When the pattern is depicted by an imaging device, the pattern depicted can be compared with a known pattern and a distortion of the corrugated board can be determined based on the comparison.

20145197 prh 14-06-2018

In one embodiment, the damping actuator 104A, 104B, 104C, 106A, 106B, 106C, 106D, 204A, 204B, 206A, 206B may adjust the surface moisture based on at least one liner 144, 148, 150 of one or more waveguides and at least two-liner corrugated board. .

In one embodiment, the damping actuator 104A, 104B, 104C, 106A, 106B, 106C, 106D, 204A, 204B, 206A, 206B can adjust the surface humidity from at least one liner 144, 148, 150 in the machine direction in one or more waves and at least binary.

In one embodiment, the damping actuator 104A, 104B, 104C, 106A, 106B, 106C, 106D, 204A, 204B, 206A, 206B can receive orientation information from the paper machine that produced the liner 144, 18, 150.

In one embodiment, the adjusting apparatus comprises an apparatus for measuring the orientation profile of the liner 144, 148, 15 150, for example in conjunction with unwinding 10. However, the measuring apparatus may be located in the manufacturing apparatus somewhere between unwinding 10 and gluing station 16B. In this case, the damping actuator 104A, 104B, 104C, 106A, 106B, 106C, 106D, 204A, 204B, 206A, 206B can receive orientation information from the orientation profile measurement apparatus.

In one embodiment, the adjusting apparatus may adjust the liner 144,

148, 150 unfolding directions based on the orientation profile.

In one embodiment, the adjusting apparatus may select to provide at least two liners 144, 148, 150 with different orientation directions, based on the orientation profile.

The single or multiple waveguide and at least two-liner corrugated board manufacturing apparatus may glue a liner 148 onto which the actuator 104A, 104B, 104C, 106A, 106B, 106C, 106D, 204A, 204B, 206A, 206B are aligned, and a corrugating paper 140, which is part of a single-sided corrugated board.

In one embodiment, the sensor arrangement 102A, 102B, 102C, 102D,

102E, 102F, 102G, 202A, 202B, 202C, 202D perform the moisture measurement optically. In one embodiment, the sensor arrangement 102A, 102B, 102C, 102D,

20145197 prh 14-06-2018

102E, 102F, 102G, 202A, 202B, 202C, 202D measure the liner 144, 148, 150 at one or more wavelengths in which water has an absorption greater than ambient wavelengths. In one embodiment, the water absorption wavelength may be, for example, about 1.4 µm, 1.9 µm and / or 2.7 µm. In one embodiment, single or multiple wave and at least binary linear measurement is performed from the liner 144, 148, 150 as a reflection measurement. The depth of penetration of optical radiation by the optical radiation into the liner 144, 148, 150 may correspond to part of the liner thickness 144, 148, 150, whereby the optical humidity measurement of the liner 144, 148, 150 can be performed. The intensity and wavelength of the optical radiation can be adapted to the properties of the liner so that the surface moisture measurement is successful. Fitting can be based on theory, simulation or experiment.

In one embodiment, the humidity is measured as the relative humidity relative to the cellulose or the basis weight of the liner 144, 148, 150. In this way, one or more waves and at least two-wave data can be obtained, for example, as a percentage of one or more waves and at least two-waves. Additionally, the sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D can measure, for example, the amount of cellulose in liner 144, 148, 150.

In one embodiment, in addition to the surface humidity, the total moisture 144, 148, 150 of the cell can be measured. In one embodiment, the measurement is made from the liner 144, 148, 150 as a diameter.

In one embodiment, single or multiple wave and at least binary linear measurement can be used to determine the linear and multiple wave and at least binary linear distribution and / or gradient of the liner 144,148, 150. The determination of the single or multiple wave and at least binary linear distribution and / or gradient can be done by measuring the surface moisture on both sides of the liner 144, 148, 150. The moisture distribution and / or gradient can be determined by measuring the surface humidity on at least one side of the liner 144, 148, 150 and liner 144 , 148, 150 total humidity.

In one embodiment, the heating apparatus is an actuator

104A, 104B may adjust the heat of the liner 150 based on a measurement of the sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D.

20145197 prh 14-06-2018

The heating apparatus 104A, 104B may heat the liner 150 from at least one face 152, 154 to equalize moisture in the machine direction of the liner 150. If the humidity is high, the heating apparatus 104A, 104B can reduce the humidity.

Further, in one embodiment, the actuator humidifier assembly 106A, 106B may adjust the humidity of the liner 150 based on a measurement of the sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D. the humidifier assembly 106A, 106B may humidify the liner 150 from at least one face 152, 154 to equalize moisture in the machine direction of the liner 150. If the humidity is low, the heating apparatus 104A, 104B can increase the humidity.

Similarly, for example, a steam box or other humidifier may be used as actuator 112A for humidity control of corrugated paper 120. The temperature control, in turn, can be used as actuator 112B, for example with a steam cylinder with a variable contact angle or other heater device.

In one embodiment, liner 148, 150 may be moistened with moisture contained in excess 224. In this case, the sizing unit 16A and the sizing station 16B may also act as actuators acting on the moisture of the liner 148, 150. Adhesive unit 16B comprises dispensing rollers 220, 222 which transfer adhesive 224 to the ridges of corrugating paper 120. When the gluing unit 16A glues the corrugated paper 120 to the liner 150, the glue 224 engages the liner 150 and dampens it in its contact area.

Similarly, the gluing station 16B, where at least one-wave and single-liner corrugated board is glued to the corrugating paper 148, will then adhere to the liner 148 and wipe it with the contact area. The moisture, dry matter content and / or amount of the adhesive affects the moisture of the liner 148, 150 and thus the corrugation of the corrugated board.

In one embodiment, the heater apparatus 104A, 104B, 204A,

204B comprises at least one drying cylinder as shown by the heating apparatuses of Figures 2 and 3. The temperature adjustment of the liner 144, 148, 150 is then made by changing the contact angle of the drying cylinder based on the measurement of the sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D. The change of contact angle can be effected by moving the roller 200, whereby the area of the liner 144, 148, 150 against the drying cylinder increases or increases

20145197 prh 14-06-2018 (curved arrow next to the heater). The longer the contact angle, the more the dryer cylinder heats the liner 144, 148, 150. The heat of the dryer cylinder may come from the hot steam contained within the dryer cylinder.

In one embodiment, the heater apparatus 104A, 104B, 204A,

204B comprises an infrared heater (not shown) that adjusts its heating power based on a measurement of a sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D.

In one embodiment, the heater apparatus 104A, 104B, 204A, 204B comprises an induction heater (not shown) that controls the heater 10 based on a measurement of a sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D.

In one embodiment, said humidifier apparatus 106A, 106B, 106C, 206A, 206B comprises a steam box (not shown in the figures) that adjusts the amount of steam applied to the liner 144, 148, 150. In one embodiment, the steam box adjusts the temperature of the steam applied to the liner 144, 148, 150. Using the steam box, it is possible to achieve energy optimization.

In one embodiment, the humidifier apparatus 106A, 106B, 106C, 206A, 206B comprises a water nozzle assembly (not shown) that adjusts the amount of water jet applied to the liner 144, 148, 150. In one embodiment, the water nozzle assembly comprises a water temperature control member (not shown in the figures) that controls the temperature of the water jet directed to the liner 144, 148, 150.

In one embodiment, the sensor arrangement 102A, 102B, 102C, 102D, 102E, 102F, 102G, 202A, 202B, 202C, 202D may also measure the temperature of the liner 144, 148, 150. The heater apparatus 104A, 104B, 204A, 204B can then adjust the temperature of the liner 144, 148, 150 based on the surface moisture measurement and temperature. Similarly, the humidifier apparatus 106A, 106B, 106C, 206A, 206B may adjust the humidity of the liner 144, 148, 150 based on the surface moisture measurement and temperature.

Figure 4A shows the change in humidity and temperature as a function of time as the three different rolls of paper 12 change in the manufacture of corrugated board. Humidity is expressed as a percentage and time is expressed in hours and minutes. The temperature is shown in Celcius11

20145197 prh 14-06-2018, and the time is expressed in hours and minutes on the same scale as the humidity, since temperature and humidity are measured simultaneously. Curve 300 represents the moisture of the unrolled roll of paper. Curve 302 shows surface moisture of liner 150 on first surface 152 which is glued to corrugated paper

120 closed. Curve 304 shows the surface moisture of liner 150 on another surface 154, which may be a non-adhesive outer surface of corrugated board.

Curve 306 shows the temperature of the unrolled paper roll. Curve 308 shows the surface temperature of liner 150 on first surface 152 which is glued to corrugated paper 120. Curve 310 shows the surface moisture of liner 150 on another surface 154, which may be a non-adhesive outer surface of corrugated board. From the curves, it is noted that as the paper roll changes from roll 1 to roll 2, the temperature momentarily rises slightly, while when moving from roll 2 to roll 3, the temperature drops slightly. If the humidity of liner 150 were to be controlled by temperature alone, heating of liner 150 would be reduced due to temperature rise. This adjustment, however, would go in the wrong direction, since moisture measurement indicates that liner 150 from reel 2 is much wetter than liner 150 from reel 1. Thus, even though liner 150 rises when changing reel, liner 150 must actually be heated further to correct surface moisture and / or total humidity. Similarly, when moving from roller 2 to roller 3 based on temperature, heating would be increased, although according to surface moisture measurement, heating should be reduced. Figure 4A also shows that moisture measurements on different surfaces 152, 154 of liner 150 can reveal the difference in moisture between the surfaces, which indicates the moisture distribution in the liner thickness direction. The moisture distribution and / or humidity gradient can be used to adjust the humidity and / or the total moisture content of 150 different surfaces of the liner for better gluing.

Temperature and surface humidity changes also occur within a single roll of paper. Also in such a situation, the surface moisture measurement can change the surface moisture of the liner 150. This also applies to the liner 144 on the surface of the single-sided corrugated board.

20145197 prh 14-06-2018

From Fig. 4A, it can be concluded that the temperature conditioning of the liner is not essential for surface moisture control, but that the temperature may be allowed to vary. In this case, the total moisture and / or surface humidity of the liner 150 can be adjusted more effectively.

Figure 4B shows the measured humidity M of liner 150 as a function of time T on freely selected scales and actuator power P as a function of time T on freely selected scale. Moisture M may refer to surface moisture on the first surface 152 of liner 150 which is glued to corrugated paper 120. The measurement may have been made by some sensor arrangement 102A, 102B, 102C, 102D. In this case, it is conceivable that the measurement is made by a sensor arrangement 102B or 102C. In the case of curve 300, liner 150 is not moistened or heated. In the case of curve 302, the liner is moistened and heated. The moisture content of the liner 150 is initially fairly uniform. At time TO the liner roll replacements, the humidity of the second roll liner, especially at the outset, is significantly higher than that of the previous roll liner. After a while, the moisture in the second liner will even out, but in this example it will be slightly different than the moisture in the first roll. At T1, a new liner change occurs. In this case, the humidity of the third liner is clearly lower than the other liner at the beginning. Again, the humidity will level off after a while.

Curve 302 shows a corresponding humidity measurement, but then the heater is switched on 104A, 104B, or its power is increased at time TO according to curve 304. The heating intensity may also be increased shortly before TO, when the moisture change is about to arrive at the gluing unit 100, or shortly after TO, when the other moisture content is still high and affects the production of corrugated board. The heating intensity can be increased and decreased during the heating intensity change. From curve 302, it can be seen that although the change in humidity in the case of curve 302 is not quite as great as in the case of curve 300, the duration of the change in humidity can be shortened by heating. Similarly, if the measurement of warmth is started before the humidity change, moisture may also be present

20145197 prh 14-06-2018 Reduces the size of the change. On the other hand, it is also possible to increase the humidity rise and / or to extend the duration of the humidity change by reducing heating.

In the case of curve 302, at the time T1, the humidification of the transducer can be increased according to curve 306, whereby the change in humidity of the third liner is shorter in time than in the non-humidified case of curve 300. Humidification can be increased and decreased in stages in the same way as heating. The wetting may be added shortly before T1, when the moisture change is about to arrive at the gluing unit 100, or after T1, when the change in humidity of the liner is still large and affects the production of corrugated board. Humidity and temperature fluctuations and prior art control problems also apply to the single-sided corrugated liner 144.
