Description

Device and method for transferring a fibrous web

The invention relates to a device for transferring a paper, cardboard, tissue or other fibrous web into a target area in a machine for producing and/or refining the paper, cardboard, tissue or other fibrous web, having a separating device for separating the fibrous web into a transfer strip and a residual web at a first edge of the fibrous web, wherein the transfer strip and the residual web contact a rotating roller via their sides opposite the top side of the fibrous web and partially wrap the roller and are guided out of the machine downwards before the target area, and wherein a transfer device is provided for transferring the transfer strip to a subsequent machine element of the target area, and wherein the separating device is designed to be movable transversely to the web travel direction for widening the transfer strip.

The invention also relates to a method for transferring a paper, cardboard, tissue or other fibrous web in a machine for manufacturing and/or refining a paper, cardboard, tissue or other fibrous web.

For example, in papermaking, such devices are used to feed a new web head into a target roll, which is designed, for example, as a drying cylinder or as a web guide roll for deflecting the paper web or around which the paper web is to be wound, during the commissioning of the papermaking machine or after the paper web breaks. This transfer is performed section by section in the paper machine. Here, the cut narrow transfer strip is transferred into a subsequent paper machine section. The remaining web is led out of the machine down to the beater, dissolved and recycled. As the transfer strip advances wider due to the movement of the separating element transversely to the web travel direction, the remaining web narrows and becomes less stable in its travel. This can lead to a fluttering of the remaining web, which can enter the target region in an uncontrolled manner, as a result of which a break can occur. In addition, paper scraps may also be deposited in the machine.

Devices for solving this problem are known. Document EP 1903142B 1 describes a system for a widening run of a fibrous web. A stabilizing device for acting on the underside of a fibrous web is disclosed. The stabilizing device is, for example, loaded with or generates a negative pressure in order to stabilize the remaining web.

On the one hand, the known devices are complicated to install and to operate. Energy is required to generate a vacuum to stabilize the fibrous web. On the other hand, the negative pressure causes friction between the fibrous web and the stationary stabilizing device. This can lead to dust accumulation.

The object of the invention is therefore to simplify and improve the stabilization of the fibrous web during the transfer.

This object is achieved according to the invention by the features of claim 1. A device for transferring a paper, cardboard, tissue or other fibrous web into a target area in a machine for producing and/or refining the paper, cardboard, tissue or other fibrous web is proposed, which has a separating device for separating the fibrous web into a transfer strip and a residual web at a first edge of the fibrous web, wherein the transfer strip and the residual web contact a rotating roller via their side opposite the top side of the fibrous web in front of the target area and partially wrap the roller and are guided out of the machine downwards by the roller, and wherein a transfer device is provided for transferring the transfer strip to a subsequent machine element of the target area, and wherein the separating device is designed to be movable transversely to the web travel direction for widening the transfer strip.

According to the invention, it is proposed that a stabilizing element can be positioned between the rotating roller and the subsequent machine element, before or during the widening of the transfer strip, opposite the top side, in the region of the remaining web, for stabilizing the transfer strip, wherein the stabilizing element at least partially covers the remaining web and the remaining web is guided out between the rotating roller and the stabilizing element.

The rotating roller can preferably be designed as a drying cylinder.

By arranging the stabilizing element opposite the top side of the fibrous web, i.e. in the space between the fibrous web and the target area, the stabilizing element can be designed passive, i.e. without the use of a vacuum. Furthermore, the stabilizing element is designed such that it can be positioned in the paper machine. This offers the possibility of positioning it only for the transfer process in the paper machine and removing it again for the production run or of being brought into a parking position inside or outside the paper machine. In this case, no disturbing air flows, or no disturbing desired air flows, are generated by the stabilizing element. This applies in particular if the device is provided for a dryer section.

The fibrous web is separated into a transfer tape and a residual web by a separation element. At the beginning of the separation process, the transfer strip is narrower than the remaining web and is arranged at the first edge of the fibrous web. In an advantageous embodiment, the first edge of the fibrous web corresponds to the operator side of the device. After the transfer of the transfer strip into the target area by means of a transfer device known per se, such as a blow-scraper, the separating device is moved in the direction of the drive side of the device. The remaining web becomes narrower and narrower in this way and the web travel becomes less and less stable. The stabilizing element now prevents the remaining web from moving in the direction of the target area, for example in the direction of a subsequent roller or a subsequent clothing, in a simple manner, preferably in the region of the drive-side edge of the remaining web.

The two sides of the paper machine are commonly referred to as the operator side and the drive side. The operator side is here the operating side for the paper machine operator. Transfer strips are formed at the edge of the operator side of the fibrous web in order to be able to control and influence the transfer process. The drive and the auxiliary units of the paper machine are arranged on the drive side and are therefore only accessible to the operator to a limited extent.

In an advantageous embodiment, the distance between the stabilizing element and the rotating roller and/or the top side of the running residual web during the stabilization of the transfer strip is less than 150 mm. This contributes to the stabilizing effect of the particularly narrow residual web and avoids breakage.

In a practical embodiment, the stabilizing element is designed to be rotatable parallel to the axis of the rotating roller. This assists in guiding the remaining web down from the paper machine into the beater.

In a practical case, the direction of rotation of the stabilizing element is opposite to the direction of rotation of the rotating roller.

Preferably, the stabilizing element has a rotary drive. Preferably, the rotational speed is adjustable. This also assists in guiding the remaining web from the paper machine down into the pulper.

Furthermore, the stabilizing element can be arranged at an edge of the fibrous web opposite the first edge and is preferably dimensioned such that the maximum coverage of the remaining web transverse to the web travel direction is 20mm to 800mm, in particular 20mm to 500mm, preferably 150mm to 250 mm. Preferably, the first edge corresponds to an operator-side edge of the fibrous web, so that the edge opposite the first edge corresponds to a drive-side edge of the fibrous web in this case. In the edge region on the drive side, the initially wide remaining web is only partially covered by the stabilizing element, which on the one hand reduces the structural complexity and on the other hand makes the handling of the stabilizing element easier. The remaining web is completely covered only when its width reaches the width of the stabilizing element during the widening travel of the transfer strip.

Depending on the parameters of the remaining web, it may be sufficient for the stabilizing element to cover the remaining web only partially during the stabilization of the transfer strip before the transfer strip is widened.

However, if the stabilizing element completely covers the remaining web during the stabilization of the transfer strip before the transfer strip is widened, a complete forced guidance of the remaining web occurs.

An advantageous development provides that the stabilizing element presses the remaining web against the rotating roller with an adjustable force during the stabilization of the transfer strip. This is advantageous for the stabilization effect, especially when the remaining web is narrow, and avoids breakage.

In a possible embodiment, the stabilizing element is mounted on the holder in such a way that its position can be changed transversely and/or in the web travel direction, preferably vertically. This is advantageous for covering as full a web width, a web position and a cutting position as possible of the remaining web.

The positioning of the stabilization element can be effected manually or automatically for this purpose.

In a practical case, the fibrous web is guided partially around a rotating roller, wherein the fibrous web is arranged between the drying wire and the rotating roller. The drying wire presses the fibrous web against the surface of the rotating roll. The drying wire is then guided away from the rotating roll, thereby forming a take-off line. In the production run, the fibrous web continues to travel together with the drying wire. During the transfer of the fibrous web, the fibrous web and the drying wire are separated. The fibrous web continues on the rotating roller until it reaches the doctor blade, which breaks the fibrous web off so that it can pass down into the beater. The process of transferring the fibrous web into the target area then begins.

Advantageously, the stabilizing element is positioned directly before the subsequent doctor blade in the direction of rotation of the rotating roll and preferably after moving away from the wire.

A stabilizing zone is formed between the removal line and the stabilizing element, in which zone the travel of the remaining web is stabilized.

The position of the stabilizing element may be indicated by the vertical distance from an imaginary horizontal plane extending through the center of the rotating roller. The stabilizing element is arranged below the horizontal plane. This applies to the stabilizing element contacting the remaining web and also to the stabilizing element arranged at a distance from the remaining web. The distance from the horizontal plane to the upper edge of the stabilizing element is preferably measured.

The rotating roller has a roller radius. The vertical distance may be in the range of less than or equal to 0.9 times the roller radius, preferably in the range of less than or equal to 0.83 times the roller radius, in particular in the range of less than or equal to 0.6 times the roller radius. Whereby the size of the stabilization zone can be optimized.

Advantageously, the vertical distance may be in the range of greater than or equal to 0.4 times the roller radius, preferably in the range of greater than or equal to 0.45 times the roller radius, in particular in the range of greater than or equal to 0.5 times the roller radius. The size of the stabilization zone can also be optimized in this way.

The stabilizing elements can be designed as rollers, guide rollers. This enables a very simple and low cost solution.

In order to protect the remaining web, the guide roller as a stabilizing element can have an elastic roller sleeve.

The guide rollers used as stabilizing elements may have a diameter of between 30mm and 500mm, preferably between 30mm and 300mm, in particular between 30mm and 200 mm.

Advantageously, the guide rollers used as stabilizing elements comprise a material selected from the group consisting of aluminium, V2A steel, V4A steel, cast iron, plastic, titanium, brass, bronze.

In a possible development, the guide rollers used as stabilizing elements comprise a coating or a roller sleeve consisting of the following material group: rubber, polyurethane, teflon and carbon fiber reinforced plastics.

The roller shell can also be designed as a single-wire fabric.

The guide rollers serving as stabilizing elements can be multiply supported.

The stabilizing element can alternatively also be designed as a blowing device. Whereby fluid is blown onto the remaining web in the covered area for stabilization.

In special cases, a simple design of the stabilizing element may also be sufficient in terms of the properties of the remaining web. Thus, the use of a foil, brush, paddle, air cushion may be sufficient.

It is also possible to use blow pipes arranged transversely to the direction of travel of the remaining web, which blow at least one fluid, for example air, beam onto the remaining web and thereby stabilize the travel of the remaining web.

In a possible further development, blow pipes are used which are arranged transversely to the direction of travel of the residual web and blow at least one fluid, for example air, jet onto the residual web and cooperate with guide surfaces which extend in the direction of travel of the residual web in order to stabilize the travel of the residual web.

It is also possible for the stabilizing element to be designed as a belt guided around two or three or more rollers.

The technical problem is also solved by a method according to claim 12. A method of transferring a paper, cardboard, tissue or other fibrous web into a target area in a machine for manufacturing and/or refining the paper, cardboard, tissue or other fibrous web (9). A separating device is provided for separating the fibrous web into a transfer strip and a residual web at a first edge of the fibrous web, wherein the transfer strip and the residual web contact a rotating roller via their side opposite the top side of the fibrous web in front of the target area and partially wrap the roller and are guided out of the machine downwards by the roller, and wherein the transfer strip is transferred by the transferring device to a subsequent machine element of the target area, and wherein the separating device is designed to be movable transversely to the web travel direction for widening the transfer strip. According to the invention, it is proposed that a stabilizing element be positioned opposite the top side in the region of the remaining web between the rotating roller and the subsequent machine element for stabilizing the transfer strip before or during the widening of the transfer strip, wherein the stabilizing element at least partially covers the remaining web and the remaining web is guided out downwards between the rotating roller and the stabilizing element.

The stabilizing element is preferably designed as a roller and is arranged at the edge of the fibrous web opposite the first edge.

The stabilizing element is preferably dimensioned such that the amount of coverage of the remaining web transversely to the web travel direction amounts to 20mm to 800mm, in particular 20mm to 500mm, preferably 150mm to 250 mm.

The invention also relates to the use of a device according to claims 1 to 11 for transferring a fibrous web into a target area in a machine for producing and/or refining a fibrous web. According to the invention, the target area is the first or second drying drum of the first dryer group of the drying section or the pre-drying section or the post-drying section.

The invention also relates to the use of a device according to claims 1 to 11 for transferring a fibrous web into a target area in a machine for producing and/or refining a fibrous web. According to the invention, the target area is a size press (leimpress).

Further features and advantages of the invention will emerge from the following description of a preferred embodiment with reference to the accompanying drawings.

In the attached drawings

Figure 1 shows a schematic side view of the transition between the press section and the dryer section together with an arrangement according to the invention;

fig. 2 shows a simplified view of the rotating roll (4) looking into the direction of production;

figure 3a shows a part of figure 1 together with an alternative stabilising element,

fig. 3b shows a detail of fig. 1 together with a further alternative stabilization element.

According to fig. 1, the fibrous web 9 is transferred during normal operation from the forming wire 10 of the former for forming the sheet material to a water-absorbing dewatering belt 11 running continuously around above the fibrous web 9 for dewatering the fibrous web 9 in a subsequent press section. The press section as shown here comprises one or usually more press gaps through which the fibrous web 9 is guided together with at least one dewatering belt 11, 12, respectively.

In fig. 1, the fibrous web 9 travels together with the upper and lower dewatering belts 11, 12 through the only press nip formed by the two press rolls 13, 14. After the press nip, the upper dewatering belt 11 is guided away from the fibrous web 9 and the fibrous web 9 is transferred from the lower dewatering belt 12 to an air-permeable, continuously circulating drying wire 15 of a subsequent drying aggregate for drying the fibrous web 9. The transfer of the fibrous web 9 is supported by a guide roller 20, the guide roller 20 being covered by the drying wire 15 and being sucked during the transfer.

In the drying assembly, the fibrous web 9 is alternately guided by the drying wire 15 onto the heated drying cylinder 16 and the suction guide roller 17, wherein the drying wire 15 presses the fibrous web 9 against the hot outer circumferential surface of the drying cylinder 16. The drying cylinders 16 are all arranged below the fibrous web 9, while the guide rollers 17 are located above the fibrous web 9. The fibrous web 9 can thus be easily guided to the machine stack at a break or during transfer and collected there in the beater 18. For this purpose, the first drying cylinder 16 is assigned a doctor blade 8, which doctor blade 8 removes the fibrous web 9, its residues or other impurities from the outer circumferential surface. Here, the row of drying cylinders 16 is located above the row of guide rollers 17. In order to ensure that the fibrous web 9 is guided over the drying wire 15 between the drying cylinders 16, suction boxes 19 are respectively provided in the drying wire loop between two adjacent drying cylinders 16. In normal operation, the underpressure of the suction box 19 sucks the fibrous web 9 onto the drying wire 15. The

suction guide rollers

17, 20 have perforated roller jackets, the inner space of which is connected to a source of underpressure.

During the start-up of the machine or upon a break, the transfer tape 3 is separated from the fibrous web 9 by the separating device 2, the transfer tape 3 then having to be transferred into the target area 1 downstream of the machine. For example, the separating device 2 is arranged in the former, wherein the transfer strip 3 is separated at the edge of the fibrous web 9 on the operator side 22 of the machine. The remaining web 20 of fibrous web 9 is guided from the forming wire 10 into the mechanical stack. The separating device 9 is formed here by one or two water jet nozzles which direct their water jets at the fibrous web 9 supported on the forming wire 10 and separate the discharge web tip from the fibrous web 9. Basically, the separating device 2 can also be arranged at other locations in the paper machine, wherein the fibrous web 9 can also be cut in the areas supported by the wire or in the areas free of support, for example in free draw. Instead of a nozzle for the discharge of the liquid, a laser or mechanical separating device, such as a rotating, preferably toothed circular knife, a stationary knife or a needle, can also be provided. However, mechanical separating means are usually used only when the fibrous web 9 is running unsupported.

The transfer strip 3 is guided by dewatering belts 11, 12 through the press section and transferred onto the drying wire 15 of the subsequent dryer group. Starting from the drying wire 15, the transfer strip 3 is brought into contact with a rotating roller 4 in the form of a first drying cylinder 16 of the dryer group. After partial coating of the first dryer cylinder 16, the transfer strip 3 is guided down into the machine stack, in particular into a beater 18 arranged there. The transfer strip 3 then widens gradually until the entire width of the fibrous web 9 reaches the rotating roller 41 and is also guided out to the beater 18. The underside of the fibrous web 9 opposite the top side 9.1 is in direct contact with an internally heated rotating roller 4, which is designed as a drying cylinder. The drying wire 15 is pressed against the top side 9.1 of the fibrous web 9. During the downward entry of the fibrous web 9 into the beater 18, the drying wire 15 is guided away from the surface 9.1 at the removal line 15.1 and to the next guide roll 17. The separating device is then moved back into its starting position. This first transfer step can also be achieved by transferring the fibrous web 9 with the full width without cutting the transfer strips, when the wet end design of the paper machine is suitable.

The present invention can be advantageously used for the following transfer step. In order to transfer the fibrous web 9 into the target area 1, a new transfer strip 3 and a residual web 20 are formed from the fibrous web 9 covering the rotating roller by the separating device 2. As is known, the transfer strip 3 is transferred from the coated roll 4 to the subsequent machine element 5 by means of a not shown blowing device, in the form of a drying wire 15 of the first dryer group, which wire is guided out of the roll 4. The subsequent machine element 5 can alternatively also be formed by a rotating roller. The widening travel is also effected after this new transfer stripe 3 has been completely transferred into the new target region 1. It is important here, however, that the remaining web 20 passes reliably from the rotating roller 4 down into the mechanical stack, in particular into the beater 18. In particular, in the case of the danger of a widening travel of the transfer strip 3, the remaining web 20 travels uncontrolled together with the following machine element 5, thus leading to edge defects or breaks. In order to stabilize the travel of the remaining web 20, a stabilizing element 6 facing the top side 9.1 of the fibrous material 9 is therefore positioned on the drive side 21 in the space between the rotating roller 4 and the subsequent machine element 5 before or during the widening travel of the transfer strip 3. The stabilizing element 6 is arranged in the vertical direction between the removal line 15.1 of the drying wire 15 and the doctor blade 8. The vertical distance 24 of the stabilizing element 6 from the horizontal plane 23 is in this case in the range of less than or equal to 0.9 times the roller radius Rw below the horizontal plane 23. The vertical distance 24 may also be in the range of less than or equal to 0.83 roll radii or in the range of less than or equal to 0.6 roll radii. Whereby the size of the stabilization zone can be optimized. For certain applications, it is expedient for the vertical distance 24 to be in the range of greater than or equal to 0.4 times the roller radius, preferably in the range of greater than or equal to 0.45 times the roller radius, in particular in the range of greater than or equal to 0.5 times the roller radius. In the example shown in fig. 1 and 2, the stabilizing element 6 is formed by a guide roller 6 parallel to the axis of the rotating roller 4. In this case, according to fig. 2, the guide rollers 6 are positioned in such a way that: which, before the widening travel, only partially covers the remaining web 20 and the drive-side edge of the remaining web 20 is reliably guided out between the rotating roller 4 and the guide roller 6 down into the beater 18. The positioning of the guide rollers 6 can be done by pivoting or also by translation parallel to the roller axis or perpendicular to the roller axis. In this way the fibrous web 9 is guided through the machine in stages. The transfer device according to the invention can therefore also be implemented at different locations of the machine. In the design shown in fig. 1, the guide roller 6 is arranged directly in front of the doctor blade 8 of the rotating roller 4 following in the direction of rotation. Thereby ensuring that the remaining web 20 enters the beater 18 between the guide roll 6 and the doctor blade 8. Furthermore, the guide roller 6 presses the remaining web 20 slightly against the rotating roller 4, i.e. the drying cylinder 16. In machines operating at high speeds, the guide roller 6 can therefore have its own rotary drive. The position of the guide roller 6 can advantageously be varied transversely to the web travel direction 7, in order to control all web widths, coverage and cutting positions of the separating device 2. The guide rollers 6 have a diameter of between 30 and 300mm and a width of between 20 and 500 mm. Further, the guide roller 6 has an elastic cover made of rubber, PU, fabric or the like to protect the outer circumferential surface of the rotating roller 4.

Fig. 2 shows a simplified device view of the rotating roller 4, viewed in the direction of production, during the widening travel of the transfer strip 3. For the sake of clarity, the drying wire 15 is not shown. The transfer ribbon 3 has been transferred to the subsequent machine element 5. The transfer strip 3 and the remaining web 20 are separated by a cutting line 2.1, which is produced by the separating device 2. The transferred transfer strip 3 leaves the surface of the drying cylinder 16 at the removal line 15.1 together with the drying wire 15. A stabilizing element 6 designed as a guide roller is arranged in the drive-side region of the remaining web 20.

Fig. 3a shows a detail of fig. 1 together with an alternative stabilization element 6. The difference from fig. 1 and 2 is that instead of a guide roller as a stabilizing element 6, a blow pipe arranged transversely to the web travel direction of the remaining web is used, which blows at least one fluid, for example air, beam onto the remaining web 20 and thereby stabilizes the travel of the remaining web 20. The vertical distance 24 of the stabilizing element 6 from the horizontal plane 23 lies in this case in the range of less than or equal to 0.9 times the roller radius Rw. The vertical distance 24 may also be in the range of less than or equal to 0.83 roll radii or in the range of less than or equal to 0.6 roll radii. Whereby the size of the stabilization zone can be optimized. For certain applications, it is expedient for the vertical distance 24 to be in the range of greater than or equal to 0.4 times the roller radius, preferably in the range of greater than or equal to 0.45 times the roller radius, in particular in the range of greater than or equal to 0.5 times the roller radius.

Fig. 3b shows that in a possible further development, a blow pipe arranged transversely to the web travel direction 7 of the remaining web 20 is used, which blows at least one fluid stream, for example an air stream, onto the remaining web and interacts with a guide surface, for example a guide plate, extending in the web travel direction 7 of the remaining web 20 in order to stabilize the travel of the remaining web 20. The stabilizing element 6 thus comprises a blow tube with a guide surface. The fluid beam may also be directed along a guide plate, whereby the remaining web 20 is sucked by the fluid beam and stabilized along the guide plate. The vertical distance 24 of the stabilizing element 6 from the horizontal plane 23 is in this case in the range of less than or equal to 0.9 times the roller radius Rw. The vertical distance 24 may also be in the range of less than or equal to 0.83 roll radii or in the range of less than or equal to 0.6 roll radii. Whereby the size of the stabilization zone can be optimized. For certain applications, it is expedient for the vertical distance 24 to be in the range of greater than or equal to 0.4 times the roller radius, preferably in the range of greater than or equal to 0.45 times the roller radius, in particular in the range of greater than or equal to 0.5 times the roller radius.
