Abstract
A machine for the manufacture or treatment of a material web, in par-ocular of a paper or cardboard web, comprises a rope guide for the threading of a marginal web strip. The rope guide has two endless ropes which can be brought together to form a rope nip and whose run course can be correspondingly changed for the positioning of the rope nip in a threading position within a plane extending in the machine running di-rection and perpendicular to the material web.
Description
Voith Paper Patent GmbH V 2708 ~1 machine for the maaufactuse or treatmeat of a material web The invention relates to a machine for the manufacture or treatment of a material web, in particular of a paper or cardboard web, comprising a rope guide for the threading of a marginal web strip which includes two endless ropes which can be brought together to form a rope nip.
A paper making machine of this kind is described, for example, in DE-C-40 34 661.
The procedure is normally as follows, for example, for the threading of the web to be dried into the dryer section: The web formed and mechanically dewatered in the start part (sieve section and press section) of the paper making machine temporarily runs only up to the end of the press section during the start-up phase and from there into a pulper, with a narrow marginal strip being separated from the web and transferred into the dryer section. As soon as the tip of this marginal strip has reached the end of the dryer section, the marginal strip is gradually broadened until it has reached the full web width.
For the threading of the material web, for example, into the dryer section or also into any desired other section of the paper making machine, in particular a rope guide can now be used whose two ropes converge or run together to form a so-called rape nip such that the tip of the marginal strip can be gripped and transported on. A deflection device can be provided in front of the rope nip in the web running direction and the tip of the arriv-ing marginal strip is laterally deflected into the rope nip out of the region of the web width thereby.
The ropes of a respective rope guide are usually guided transversely to the machine running direction in order to prevent interference or a collision of these ropes with other moving parts, for example of a scanning device or the like. In this respect, however, a crossing over of the ropes now fre-quently occurs, which involves heavy wear of the ropes in view of the friction between the ropes and the additional deflection at right angles around rope pulleys.
It is the aim of the invention to provide an improved machine of the kind initially mentioned in which the above-mentioned disadvantages are eliminated.
This object is satisfied in accordance with the invention by a machine for the manufacture or treatment of a material web, in particular of a paper or cardboard web, comprising a rope guide for threading a marginal web strip, which includes two endless ropes which can be brought together to form a rope nip, and whose ntn course can be correspondingly changed for the positioning of the rope nip in a threading position within a plane extending in the machine running direction and perpendicular to the material web.
It is now possible on the basis of this design to transpose the ropes gener-ally in the machine running direction such that the rope nip is generated at an optimum position for the threading or is transposed into such an optimum threading position. The ropes are subsequently retracted again in order to allow trouble-free operation or trouble-free handling of a device provided in each case in the region of the threading point, for example a scanning device or the like. If, for example, a web scanning device is pro-vided in this region, in particular a full web scan is also again possible after a respective retraction of the ropes.
In an expedient practical embodiment of the machine of the invention, the position of the rope nip can be changed within the plane extending in the machine running direction and perpendicular to the material web.
The two ropes of the rope guide are preferably guided independently of the position of the rope nip, in each case exclusively in a plane extending in the machine running direction and perpendicular to the material web.
The position of the rope nip can advantageously generally be changed in the machine running direction.
In accordance with a preferred practical embodiment of the apparatus of the invention, the two ropes of the rope guide can be guided for the posi-tioning of the rope nip in a threading position into the region of a device, in particular of a web scanning device, and can be retracted to release the device.
In an expedient practical embodiment, the ~t~vo ropes of the rope guide can be guided for the positioning of the rope nip in a threading position through the frame of a web scanning device and can be retracted again for the release of the web scanning plane.
The rope nip is advantageously adjustable between a threading position in which the two ropes of the rope guide are guided through the frame of a web scanning device and a retracted position in which the web scanning device is released again.
A paper making machine of this kind is described, for example, in DE-C-40 34 661.
The procedure is normally as follows, for example, for the threading of the web to be dried into the dryer section: The web formed and mechanically dewatered in the start part (sieve section and press section) of the paper making machine temporarily runs only up to the end of the press section during the start-up phase and from there into a pulper, with a narrow marginal strip being separated from the web and transferred into the dryer section.

In an expedient practical embodiment of the machine of the invention, the position of the rope nip can be changed within the plane extending in the machine running direction and perpendicular to the material web.
The two ropes of the rope guide are preferably guided independently of the position of the rope nip, in each case exclusively in a plane extending in the machine running direction and perpendicular to the material web.
The position of the rope nip can advantageously generally be changed in the machine running direction.
In accordance with a preferred practical embodiment of the apparatus of the invention, the two ropes of the rope guide can be guided for the posi-tioning of the rope nip in a threading position into the region of a device, in particular of a web scanning device, and can be retracted to release the device.
In an expedient practical embodiment, the ~t~vo ropes of the rope guide can be guided for the positioning of the rope nip in a threading position through the frame of a web scanning device and can be retracted again for the release of the web scanning plane.
The rope nip is advantageously adjustable between a threading position in which the two ropes of the rope guide are guided through the frame of a web scanning device and a retracted position in which the web scanning device is released again.
The rope nip grasping the tip of the marginal web strip can therefore be moved into a threading position, for example through the frame of a scan-ning device, said threading position being suitable to receive the tip of the marginal strip coming from a preceding machine element such as a press roll or a dryer cylinder. In this respect, the marginal strip can be trans-ported to the relevant transfer point by, for example, an air tray or a con-veyor belt.
A further advantageous embodiment of the embodiment of the invention is characterized in that the rope guide includes a guide section disposed in front of a web scanning device in the machine running direction and a guide section disposed after the web scanning device in the web running direction; in that the two ropes of the rope guide are guided mutually separated between these two guide sections on mutually opposite sides of the web scanning device; and in that a rope nip is formed at the start of the rear guide section and can be adjusted into a take-over position to take over the material web tip from the front guide section through the frame of the web scanning device and back into a retracted position dis-posed behind the web scanning device to transfer the material web into the rear guide section.
The two ropes can be guided over two sheaves, which can be correspond-ingly positioned via an adjustment device, to form the rope nip.
The rope guide can be provided, for example, for the threading of a mar-ginal web strip into the dryer section. Generally, however, the rope guide can also be provided for the threading of a marginal web strip into a dif ferent machine element.
The invention is described in the following by way of embodiment exam-Ales with reference to the drawing; there are shown in this:
Fig. 1 a schematic part illustration of a paper making machine comprising a rope guide for threading a marginal web strip into the dryer section;
Fig. 2 a simplified schematic illustration of the rope guide of Figure 1;
Fig. 3 a simplified schematic illustration of a further embodiment of the rope guide;
Fig. 4 a schematic plan view of an adjustment device; and Fig. 5 a schematic side view of the adjustment device of Figure 4.
Figure 1 shows a machine 10, in a schematic part illustration, for the manufacture or treatment of a material web, which can be in particular a paper web or a cardboard web.
The last press 12 of the press section and the first two dryer cylinders 14 of the dryer section of a paper making machine can be seen in Figure 1.
A rope guide 16 is provided which in the present case serves, for example, for the threading of a marginal web strip into the dryer section.
This rope guide 16 is also shown again in Figure 2 in a simplified sche-matic illustration.
As can be seen from Figures 1 and 2, the rope guide 16 includes two endless ropes 18, 20 which are brought together in the region of two sheaves 22, 24 to form a rope nip 26. In this respect, the run course of these two endless ropes 18, 20 can be correspondingly changed by means of an adjustment device 28 for the positioning of the rope nip 26 in a threading position E within a plane extending in the machine running direction L and perpendicular to the material web.
In the present case, the sheave assembly 22, 24 is correspondingly trans-posed by the adjustment device 28 with the spacing between the sheaves 22, 24 remaining the same. The rope nip 26 is therefore maintained dur-ing a respective transposition of the sheave assembly 22, 24. The position of the rope nip 26 can thus be changed within the plane extending in the machine running direction L and perpendicular to the material web can thus be changed. In this respect, the two ropes 18, 20 of the rope guide 16 are each guided independently of the respective position of the rope nip 26 only in a plane extending in the machine running direction L and perpen-dicular to the material web. The position of the rope nip 26 can generally be changed in the machine running direction L.
In the present embodiment, the two ropes 18, 20 of the rope guide 16 are guided through the frame 30 of a web scanning device 32 for the posi-tioning of the rope nip 26 in the threading position E and subsequently retracted for the release of the web scanning device 32.
The rope nip 26 can thus be adjusted by means of the adjustment device 28 between the threading position E in which the two ropes 18, 20 of the rope guide 16 are guided through the frame 30 of the web scanning device 32 and a retracted position Z in which the web scanning device 32 is again released. The sheaves adopting their retracted position Z are desig-nated with 22' and 24' respectively in Figures 1 and 2.
As can be seen by way of Figures 1 and 2, the grasped marginal web strip is guided by means of the rope guide 16 including the two ropes 18, 20 aver a deflection roll 34 into the dryer section whose first two dryer cylin-ders 14 can be seen in Fig. 1.
Figure 3 shows a further embodiment of the rope guide 16 in a simplified schematic illustration.
In this case, the rope guide 16 includes a guide section 36 disposed in front of a web scanning device 30 in the machine running direction L and a guide section 38 disposed after the web scanning device 30 in the ma-chine running direction L. The two ropes 18, 20 of the rope guide 16 are guided mutually separated between these two guide sections 36, 38 on mutually opposite sides of the web scanning device 32.
A rope nip 26 is formed at the start of the rear guide section 38. This rope nip 26 is in the present case adjustable into a takeover position E for the takeover of the material web tip from the front guide section 36 through the frame 30 of the web scanning device 32 and back into a retracted position Z disposed after the web scanning device 32 for the transfer of the material web into the rear guide section 38.
1:n this respect, the two ropes 18, 20 can be again guided over two sheaves 22, 24, which can be correspondingly positioned via an adjustment device 28 (cf. in particular also Figs. 1, 4 and S) to form the rope nip 26.
An exemplary embodiment of the adjustment device 28 is shown in Fig-ures 4 and 5.
As can be seen from these two Figures, the adjustment device 28 com-prises a sheave assembly 40, including the two sheaves 22, 24, which can be moved along a guide rail 44 by means of a piston-in-cylinder unit 42.
For this purpose, a runner 46 guided at the rail 44 is associated with the sheave unit 40. As can be seen in particular with reference to Fig. 4, a T-arm arrangement 48 is provided in the region of the sheave assembly 40.
The piston-in-cylinder unit 42 engages at a lug 50 connected to the sheave assembly 40. The resulting stroke for the sheave assembly 40 is given with h in Figure 5. In this Figure 5, a nip guard 52 provided in the region of the sheave assembly 40 can moreover be seen. At least one proximity switch 54 or the like can, for example, be provided to limit the stroke movement of the sheave assembly 40.

A further advantageous embodiment of the embodiment of the invention is characterized in that the rope guide includes a guide section disposed in front of a web scanning device in the machine running direction and a guide section disposed after the web scanning device in the web running direction; in that the two ropes of the rope guide are guided mutually separated between these two guide sections on mutually opposite sides of the web scanning device; and in that a rope nip is formed at the start of the rear guide section and can be adjusted into a take-over position to take over the material web tip from the front guide section through the frame of the web scanning device and back into a retracted position dis-posed behind the web scanning device to transfer the material web into the rear guide section.
The two ropes can be guided over two sheaves, which can be correspond-ingly positioned via an adjustment device, to form the rope nip.
The rope guide can be provided, for example, for the threading of a mar-ginal web strip into the dryer section. Generally, however, the rope guide can also be provided for the threading of a marginal web strip into a dif ferent machine element.
The invention is described in the following by way of embodiment exam-Ales with reference to the drawing; there are shown in this:
Fig. 1 a schematic part illustration of a paper making machine comprising a rope guide for threading a marginal web strip into the dryer section;
Fig. 2 a simplified schematic illustration of the rope guide of Figure 1;
Fig. 3 a simplified schematic illustration of a further embodiment of the rope guide;
Fig. 4 a schematic plan view of an adjustment device; and Fig. 5 a schematic side view of the adjustment device of Figure 4.
Figure 1 shows a machine 10, in a schematic part illustration, for the manufacture or treatment of a material web, which can be in particular a paper web or a cardboard web.
The last press 12 of the press section and the first two dryer cylinders 14 of the dryer section of a paper making machine can be seen in Figure 1.
A rope guide 16 is provided which in the present case serves, for example, for the threading of a marginal web strip into the dryer section.
This rope guide 16 is also shown again in Figure 2 in a simplified sche-matic illustration.
As can be seen from Figures 1 and 2, the rope guide 16 includes two endless ropes 18, 20 which are brought together in the region of two sheaves 22, 24 to form a rope nip 26. In this respect, the run course of these two endless ropes 18, 20 can be correspondingly changed by means of an adjustment device 28 for the positioning of the rope nip 26 in a threading position E within a plane extending in the machine running direction L and perpendicular to the material web.
In the present case, the sheave assembly 22, 24 is correspondingly trans-posed by the adjustment device 28 with the spacing between the sheaves 22, 24 remaining the same. The rope nip 26 is therefore maintained dur-ing a respective transposition of the sheave assembly 22, 24. The position of the rope nip 26 can thus be changed within the plane extending in the machine running direction L and perpendicular to the material web can thus be changed. In this respect, the two ropes 18, 20 of the rope guide 16 are each guided independently of the respective position of the rope nip 26 only in a plane extending in the machine running direction L and perpen-dicular to the material web. The position of the rope nip 26 can generally be changed in the machine running direction L.
In the present embodiment, the two ropes 18, 20 of the rope guide 16 are guided through the frame 30 of a web scanning device 32 for the posi-tioning of the rope nip 26 in the threading position E and subsequently retracted for the release of the web scanning device 32.
The rope nip 26 can thus be adjusted by means of the adjustment device 28 between the threading position E in which the two ropes 18, 20 of the rope guide 16 are guided through the frame 30 of the web scanning device 32 and a retracted position Z in which the web scanning device 32 is again released. The sheaves adopting their retracted position Z are desig-nated with 22' and 24' respectively in Figures 1 and 2.
As can be seen by way of Figures 1 and 2, the grasped marginal web strip is guided by means of the rope guide 16 including the two ropes 18, 20 aver a deflection roll 34 into the dryer section whose first two dryer cylin-ders 14 can be seen in Fig. 1.
Figure 3 shows a further embodiment of the rope guide 16 in a simplified schematic illustration.
In this case, the rope guide 16 includes a guide section 36 disposed in front of a web scanning device 30 in the machine running direction L and a guide section 38 disposed after the web scanning device 30 in the ma-chine running direction L. The two ropes 18, 20 of the rope guide 16 are guided mutually separated between these two guide sections 36, 38 on mutually opposite sides of the web scanning device 32.
A rope nip 26 is formed at the start of the rear guide section 38. This rope nip 26 is in the present case adjustable into a takeover position E for the takeover of the material web tip from the front guide section 36 through the frame 30 of the web scanning device 32 and back into a retracted position Z disposed after the web scanning device 32 for the transfer of the material web into the rear guide section 38.
1:n this respect, the two ropes 18, 20 can be again guided over two sheaves 22, 24, which can be correspondingly positioned via an adjustment device 28 (cf. in particular also Figs. 1, 4 and S) to form the rope nip 26.
An exemplary embodiment of the adjustment device 28 is shown in Fig-ures 4 and 5.
As can be seen from these two Figures, the adjustment device 28 com-prises a sheave assembly 40, including the two sheaves 22, 24, which can be moved along a guide rail 44 by means of a piston-in-cylinder unit 42.
For this purpose, a runner 46 guided at the rail 44 is associated with the sheave unit 40. As can be seen in particular with reference to Fig. 4, a T-arm arrangement 48 is provided in the region of the sheave assembly 40.
The piston-in-cylinder unit 42 engages at a lug 50 connected to the sheave assembly 40. The resulting stroke for the sheave assembly 40 is given with h in Figure 5. In this Figure 5, a nip guard 52 provided in the region of the sheave assembly 40 can moreover be seen. At least one proximity switch 54 or the like can, for example, be provided to limit the stroke movement of the sheave assembly 40.
