FIELD OF THE INVENTION

The invention relates to a method and an arrangement for adjusting the operation of a winding device. The invention also relates to a winding device.

Background of the Invention

Figure 1 illustrates a principle view of a winding device in which paper or other roll material 101 is wound around a winding axis 102. In the case of paper machines, said winding shaft is often referred to as a reel roll, and the assembly formed by the reel roll and the material around it 10 is called machine roll 104. The winder has The material to be rolled 101 passes through a nip between the winding cylinder 103 and the machine roll 104 15. The roller cylinder 103 is subjected to a torque M1 and the roller shaft 102 is subjected to a torque M2. A torque generating device M2 is often referred to as a hub drive. The winding cylinder 103 is pressed against the machine reel 104 to provide a radial component Fn (—Fn) of force acting between the winding cylinder and the machine reel, called nip force. Said nip force 20 is typically expressed as a force per machine roll width (kN / m). Other winding forces are the tangential circumferential force exerted on the surface of the machine roll 104 by the torque M2 and the tangential force exerted by the torque M1 applied by the winding cylinder to the material to be rolled 101. The roller constructed such that the transverse force profile of the force between the pressure roller and the machine roller can be adjusted. The printing roller may be subjected to a torque M3, whereby the printing roller will apply a tangential surface draw to the machine roll. The nip force between the roller cylinder and the machine roll, the circumferential force produced by the center drive of the machine roller, the web tension of the roll material 101, the tangential force exerted on the machine roller by the winding cylinder ! machine roll properties such as hardness. The aim is to make 5 of the rolls of material 101 [UL] which satisfies the conditions imposed by the process of rolling and further processing in terms of handling and roll design.

The values of said winding parameters serve as reference values for the force and torque adjustments of the winder drives. In one prior art solution, the winding machine operator staff determines suitable values for the winding parameters through experience and manual measurements. For example, the user of the reel may knock on the finished rolls to determine if the hardness of the finished rolls is appropriate and, if necessary, change the value of one or more winding parameters. However, such an adjustment method is slow and laborious.

SUMMARY OF THE INVENTION The present invention relates to a novel method of adjusting the operation of a reel device, comprising: during measurement of a reel, determining at least one quality indicator that reflects the properties of the reel being formed; and - controlling said winding device based on a setpoint of said at least one winding parameter.

Said measurement and determination methods include, for example, roll hardness measurement, which may be based on, for example, spring force collision measurement, air film thickness measurement, roll density determination, and Wound On Tension (WOT) on the machine roll surface layer. Based on the difference between the specified quality property (or -------- - 1.area 3 properties) and the desired quality property (or properties), one or more winding parameters are adjusted, such as nip force between the winding cylinder and machine roll, circumferential force the web tension of the material to be rolled, the tangential force exerted by the reeling cylinder on the machine roll, and / or the surface tension applied to the surface of the machine roll by the press roll and the shape of the force profile. The method of the invention can be used to adjust the quality characteristics of the forming machine reel by a closed control during the winding process, thus improving the quality of the reel and further reducing the workload of the reel operator compared to the 10 prior art solutions previously described herein.

The invention also relates to a novel arrangement for controlling the operation of the winding device. The arrangement according to the invention comprises measuring and data processing means for determining at least one quality indicator representing the properties of the machine reel formed during the winding process by means of measurement relating to said machine reel and an adjusting apparatus arranged to provide at least one control influence on said winding process. during said winding process, based on said at least one quality indicator, and - a second control circuit for controlling said winding device based on a set value of said at least one winding parameter during said winding process.

Brief description of the figures

Embodiments of the invention and their advantages will now be described in more detail with reference to the accompanying drawings, in which: Figure 1 is a side view of a prior art winding device, Figure 2 is a side view of a winding device having an arrangement for adjusting the operation of said winding device; and FIG. 4 is a flowchart illustrating a method of adjusting the operation of a winding device according to an embodiment of the invention.

Figure 1 is described previously in connection with the prior art description herein.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Figure 2 shows a side view of a winder device having an arrangement for adjusting the operation of said winder device according to an embodiment of the invention. The winder comprises a winding shaft 202 which is wrapped around paper or other roll material 201 to form a machine reel 204. The winder comprises a winding cylinder 203 which is pressed against the machine reel by a support apparatus 205 having power generating apparatuses such as hydraulic cylinders and -adjustable screw guides to provide clamping force. The roll material 201 5 passes through a nip between the winding cylinder 203 and the machine roll 204. The winding cylinder 203 is subjected to a torque M1 and the winding shaft 202 is subjected to a torque M2. The winding cylinder 203 is pressed against the machine reel 204 to provide a nip force Fn (-Fn) between the winding cylinder and the machine reel. The roller device may further include a press roll 206 pressed against the machine roll 204 by a support apparatus 107. The press roll may be constructed such that the transverse (co-ordinate 250 z) force profile of the force between the press roll and the machine roll can be measured and adjusted. The printing roller may be subjected to a torque M3, whereby the printing roller will apply a tangential surface draw to the machine roll. The nip force between the winding cylinder and the machine roll, the 15 circumferential force provided by the central drive of the machine roll, the web tension of the roll material 201, the tangential force applied to the machine roll of the winding cylinder hardness.

An arrangement for adjusting the operation of the reel device includes measuring and data processing means 208 for determining at least one quality indicator representing the properties of the machine reel 204 formed by the measurement on said reel during the reeling process. Said measurement is performed during said winding process. The arrangement further comprises an adjusting apparatus 212 configured to provide a first control circuit for controlling at least one winding parameter during said winding process based on said at least one quality indicator, and a second control circuit for controlling a winder during said winding process based on said at least one winding parameter. Preferably, said first control circuit and the second control circuit are cascaded relative to one another, said second control circuit being arranged to function as an inner control loop and said first control circuit being arranged to function as an outer control loop, the output of which is configured to act as a reference for said second control circuit. The adjusting apparatus 212 is arranged to control the operation of the motors 209, 210 and 211 producing torques M1, M2 and M3 and the operation of the supporting apparatuses 207 and 205. By controlling the operation of the motors 209, 210 and 211 and the support apparatuses 207 and 205, the ice apparatus is able to adjust the winding parameters.

In an arrangement according to an embodiment of the invention, the measuring and data processing means 208 are arranged to determine the density of the surface layers of the machine roll 204. In this case, the determined density represents a quality indicator determined from the machine reel, based on which the reference value of at least one winding parameter is adjusted.

Measuring and data processing means 208 may be arranged to determine said density, for example, machine roll circumference vk [m / s], machine roll rotation speed Ω [rev / s], web roll speed web speed vr [m / s], and said roll material weight mA [g / m2 ]. The circumferential speed of the machine roll and the web speed of the material to be rolled can be determined, for example, by touch-measuring instruments such as measuring wheels or non-contact measuring instruments such as surface speed lasers. The peripheral speed of the machine roll may not be the same as the web speed of the material to be rolled, since the material to be rolled may be stretched during the winding process. Based on the peripheral speed of the machine roll, the radius R [m] of the machine roll can be determined from the equation: 20 R = ν ^ 2πΩ (1). The increase AV [m3] of the machine roll volume over the time interval T1 ... T2 [s] is AV = uW [R (T2) 2 -R (T1) 2], (2) where W [m] is the web width or width of the web 201 in the 250 z direction of the coordinate system, R (Ti) is the radius of the machine reel at the start of said time slot T1f and R (T2) is the radius of the machine reel at the end of said time slot T2. The increase in machine roll mass Am [kg] over the said time interval is

Am = vr W mA (T2 - Ti). (3) 7

The density p [kg / m3] of the machine roll formed during said time interval is p = Am / AV. (4)

According to another example, the measuring and data processing means 208 may be arranged to determine said density based on the measured distance D between the rotation axis of the machine roll 204 and the rotation axis of the winding roller 203, the radius Rr of the winding cylinder and the web speed vr of said roll. From the distance D and the radius R of the machine roll can be determined from the equation: R = D - Rr (5) 10. The density of the part of the machine roll formed in the time interval T1 ... T2 can be calculated using equations (2) to (4).

In an arrangement according to an embodiment of the invention, the measuring and data processing means 208 are arranged to determine the tangential tension in the surface layer of the machine roll WOT On Width On the difference between based on the elastic properties of the material. The tangential tension WOT determined here represents a quality indicator determined from the machine roll, which is used to adjust the setpoint of at least one winding parameter. The circumferential velocity of the machine roll and the web speed of the material to be rolled 20 may be determined, for example, by means of contact measuring instruments such as measuring wheels or non-contact measuring instruments such as surface speed lasers. The relative elongation ε of the material to be rolled can be calculated from the equation: ε = vk / vr - 1. (6) 25 The tangential stress WOT on the surface of the machine roll can be calculated from: WOT = Tr + εΕ, (7) 8 where E is a a known quantity that can be read from a table, for example. The term describes εΕ the additional tension in the material to be rolled during the winding process.

In an arrangement according to an embodiment of the invention, the measuring and data processing means 208 are arranged to determine the surface hardness of said machine roll. In this case, the hardness determined represents a quality indicator, which is used to set a reference value for at least one winding parameter. The measurement of the surface hardness of the machine roll may be based, for example, on the movement of the collision caused by the spring force.

10 It should be noted that the above equations are merely illustrative examples of how one or more quality indicators can be determined by measurements on a machine reel. As will be apparent to one skilled in the art, other types of measurements and mathematical procedures may also determine the quality indicators.

In an arrangement according to an embodiment of the invention, the adjusting apparatus 212 15 is arranged to adjust the set values of a plurality of roll parameters in a predetermined order of priority based on at least one quality indicator. In said order of priority, the lower winding parameter setpoint is arranged to be adjustable in response to a situation where adjusting the higher ordering winding parameter setpoint in said order of priority has not resulted in 20 sufficient changes in said at least one quality indicator. For example, suppose the adjustable winding parameters are: ri = nip force [kN / m] between the winding cylinder and the machine roll, r2 = circumferential force generated by the center drive of the machine roll [N], r3 web tension [N], r4 = force exerted by the winding cylinder on the machine roll and rs = surface tension on the pin-25 of the printing roller machine roll. It is further assumed that ranges are defined for said winding parameters, i.e., for each winding parameter, a minimum allowable value is specified, a maximum allowable value. The priority order of said winding parameters may be, for example, r2, n, r4, r5 and r3. In this case, the track tension is adjusted r3 only when the adjustments of the other winding parameters r2, rh r4 and r5 have not yet achieved the desired result, i.e., when the quality indicator deviates from its target value and the adjustment function has set each of the other winding parameters to the minimum or maximum . Said preference stiffness may also be asymmetric such that the position of each winding parameter in said order of priority depends on the direction of change of that winding parameter. For example, track tension may be the last in the said priority sequence if the track tension should be increased, but first if the track tension should be decreased.

In an arrangement according to an embodiment of the invention, the adjusting apparatus 212 is arranged to adjust the set values of a plurality of roll parameters based on at least one quality indicator. Said winding parameters are accompanied by preset weighting factors arranged to indicate the relationship between the change in the reference value of each winding parameter and the change in said at least one quality indicator. For example, suppose the adjustable winding parameters are one or more of the following: n = nip force between the winding cylinder and the machine roll [kN / m], Γ2 = circumferential force generated by the center drive of the machine roll [N], Γ3 = roll tension [N], r4 = the tangential force exerted by the tangential direction [N] and rs = the surface pull exerted by the printing roll on the surface of the machine roll. It is further assumed that the quality indicators to be determined are one or more of the following: density p, hardness h, and tangential stress WOT on the surface layer. It is further assumed that the setpoint for each winding parameter is assigned a nominal value of 20, n.refo (i = 1, 2, .... 5), which corresponds to a predetermined preferred operating point. The setpoint n> ref of the winding parameter n (i = 1.2, ..., 5) can be adjusted, for example, by the equation: H.ref "H.refO + Wj.p (p - Pref) + Wj ^ h (h - href) + Wi wOT (WOT - WOTref), (8)

Where pref, href and WOTref are the target values of the specified quality indicators and 25 Wj, p, Wj, h and Wj wot are preset weighting factors arranged to indicate the ratio of the change in the setpoint of the winding parameter to the corresponding change in the quality indicator, for example W, iP = Δη . Equation (8) corresponds to an example in which the setpoint of the winding parameter is adjusted based on three defined quality indicators (p, h, WOT). It should be noted that the number of quality indicators 30 used may also be other than three and / or the quality indicator (s) 10 may be some other quantity (s) describing the characteristics of the machine reel.

In an arrangement according to an embodiment of the invention, the adjusting apparatus 212 is arranged to adjust the setpoint ai-5 of said at least one winding parameter on the basis of at least one control indicator provided by the user. The control variable provided by the user may be, for example, the nominal value n, refo of the winding parameter reference value in equation (8).

In an arrangement according to an embodiment of the invention, the adjusting apparatus 212 is arranged to adjust the shape profile of the reel press roll 206 on at least one of the following: time variation of the shape profile of machine roll 204 and air volume measured from the machine roll. The shape of the machine roll means the radius of the machine roll as a function of the axial direction.

Fig. 3 is a control diagram illustrating the adjustment of a roller device implemented by an arrangement according to an embodiment of the invention. The control diagram includes a first control circuit 301 and a second control circuit 302. The control circuit 301 forms an outer closed control loop and the control circuit 302 forms an inner closed control loop which is part of said outer closed control loop. The target values 303 of the machine roll quality indicators are compared with the quality indicators 311 determined from the machine roll by measurements (block 309). For example, it is possible to measure the diameter / hardness profile of 20 machine rolls e.g. The measuring roll, in which the measurement is based on a pressure-sensitive membrane, may be, for example, a measuring roll known under the applicant's trade name "iRoll". The difference quantity 314, which represents the quality deviation, controls (block 304) the set values of the winding parameters. In addition, the set values of the winding parameters can also be adjusted (set) based on the control variables provided by the user (block 305). For example, the dispersion of the machine roll diameter / hardness profile can either increase or decrease the desired roll density and / or the tangential stress WOT on the machine roll surface and / or change the relationship between the various winding parameters. For example, in a situation where the diameter / hardness profile of the machine roll 30 is large, i.e. the machine roll is curled and air is trapped within the machine roll, it is preferable to increase the circumferential power instead of increasing the nip force since increasing the nip power would unwanted effect. Based on the output information of block 304, and possibly also block 305, setpoint winding parameters 313 are formed (block 306) with reference to the current winding parameters 312. Friction, mass disorders, and other possible mechanical factors (block 308), according to known physics laws, influence the forces and torques on the prevailing winding parameters. The control diagram may further include a separate control circuit for controlling (block 310) the shape of the roll of the printing roll on the basis of one or more quality indicators 311 determined from the machine roll.
