EP1291309B1 - Method and winding machine for winding a material web - Google Patents

Abstract

For the continuous winding of a paper/cardboard web (12) into a roll, the web is passed partially around a carrier drum (18) on a transport system, and the winding roll (16) is at a second transport system. A winding gap (24) between them is on a plane (E1) through the axes (20,22) of the drum and roll, with a controlled linear force in the winding gap. As the diameter of the wound roll increases, the vertical positions of the drum and roll are changed for a new reeling drum (14') to be prepared in a holder, with a new winding gap (24') between it and the carrier drum. The web is cut, and the new leading end laid on the new reeling drum, and the fully-wound paper roll is removed, for winding to continue.

Description

The invention relates to a method for the continuous winding of a material web, in particular paper or board web, on a spool to form a wound roll.
It further relates to a winding machine for continuously winding a material web, in particular paper or board web, on a spool to form a winding roll.

Such a method and such a winding machine are known for example from WO 98/52858 and EP 0 697 006 B1. They are used, for example, at the end of a production or finishing of a material web serving machine. For example, they can also be used to wrap an already finished wound reel. The machine in question may be, for example, a paper machine. Another method and a winding machine are disclosed in US 5,577,685, which represents the closest prior art.

In the known methods and winding machines of the type mentioned, the new, still empty reel is often kept in a primary storage, by means of which the new reel is moved after the web change along a curved, arc-like path to the support drum axis. However, such a movement brings with it the danger of an entanglement of drum to carry drum. Thus, during the Abschwenkvorgangs the géometric position of the spool relative to the suspension drum center changes.

The aim of the invention is to provide an improved method and an improved winding machine of the type mentioned, in which the aforementioned disadvantages are eliminated.

The method according to the invention proposed for achieving this object comprises the following steps:

• the material web is guided in part over a peripheral surface of a carrier drum which can be displaced by means of a first transport device and forms a winding nip with the first plane determined by the longitudinal axes of the carrier drum and the winding roller with the winding roll being in the winding nip via a corresponding first winding Displacement and contact pressure set, controlled or regulated by means of a carrier drum mounted in a pressure system in the first transport device ("main winding phase");
• upon reaching a predetermined roll diameter, the relative vertical position of the carrier drum and winding roll by a displacement, in particular a vertical or nearly vertical displacement, the first, the support drum supporting transport for preparing a Tambourwechsel changed so that a new through the longitudinal axes of the carrier drum and the Wickelrolle certain level is created, provided a new spool in a holding device and formed between the carrier drum and the new spool in a determined by the longitudinal axes of the carrier drum and the new spool second level, a new winding nip, wherein the formed with the winding roll old winding nip also during the overpass the carrier drum is maintained from the first to the second level;
• the material web is separated by means of at least one separating device and wound up with its new web start on the new spool ("Anwickelphase");
• the old winding roll is removed by removing the old winding nip by means of the second transport device from the carrier drum and removed from the second transport device; and
• after the winding of the new winding roll, the carrier drum and the new winding roll are preferably displaced vertically while maintaining the winding nip formed therebetween in the first plane and the new winding roll is introduced into the returned and provided second transport means, the line force in the formed winding nip during the transfer over a corresponding displacement and contact pressure is set, controlled or regulated by means of a carrier drum mounted in a pressing system in the first transporting device ("intermediate winding phase").

Due to this configuration, the advantage according to the invention arises that the use of the previously provided primary region or the previously provided primary storage for the new, still empty tambour can be completely dispensed with. The risk of entanglement of drum to the carrier drum during the displacement of the invention is thus no longer given and during the Abschwenkvorgangs invention (movement process) changes the geometric position of the spool relative to the Trägtrommelzentrum due to the slight increase in diameter of the new Winder roll only to a small extent. There are thus created the conditions for an optimal winding nip or Nippgeometrie.

In the realization of the feature that the old winding nip formed with the winding roll is maintained even during the transfer of the carrier drum from the first to the second level, entirely on a so-called and well-known Luftabquetschelement, for example in the form of a brush or a Ausbreitstange be dispensed with to avoid air pockets between the individual layers of the wound material web.

The reproduced in a purely schematic representation in Figure 1 winding machine 10 is used for continuously winding a web 12 on a spool 14 to form a winding roll 16. The web 12 may be, for example, a paper or board web.

In this case, in a step A, the material web 12 is guided over a displaceable carrying drum 18, which forms a winding gap 24 with the displaceable winding roller 16 in a first through the longitudinal axes 20, 22 of the carrier drum 18 and the winding roller 16 certain plane E1, wherein the line force in Winding nip (24) is set, controlled or regulated by means of a corresponding displacement and contact pressure of the carrier drum (18) mounted in the first transport device 26 in a pressure system 30 ("main winding phase"). The plane E1 can in particular run at least substantially horizontally.

The line force in the winding nip 24 is set, controlled or regulated via a corresponding, preferably horizontal displacement and contact pressure of the carrier drum 18. The diameter of the winding roll 16 can be compensated in particular via a corresponding, taking place in the first plane E1 horizontal displacement of the winding roll 16.

The winding roller 16 may therefore be correspondingly weg- and force-controlled, wherein the force control can be integrated into the path control. The diameter increase is compensated by the path control.

As indicated by the various dashed lines reproduced positions of the carrier drum 18, the line force direction can be varied within 180 ° so that it runs regardless of the respective position of the carrier drum 18 each along a line passing through the axes of the carrier drum and the winding roll 16.

Upon reaching a predetermined roll diameter, the relative vertical position of the carrier drum 18 and winding roll 16 by a displacement, in particular a vertical or nearly vertical displacement of the carrier drum 18 to prepare a Tambourwechsels changed so that a new through the longitudinal axes 20, 22 of the carrier drum 18th and the winding roll 16 certain level E1 'is formed. In this case, in the present exemplary embodiment, the carrier drum 18 is simultaneously displaced vertically out of the first plane E1 into a second plane E2 which is at least essentially parallel thereto, which in particular can again run horizontally (see step B).

In the present case, in this second level E2 a new drum 14 'in a holding device, not shown (see step C) and between the carrier drum 18 and the new spool 14' in one of the longitudinal axes 20, 22 of the carrier drum 18 and the new Tambours 14 'certain second level E2 a new winding nip 24' is formed (see step D).

The formed with the winding roll 16 old winding nip 24 is maintained even during the transfer of the carrier drum 18 from the first plane E1 in the second plane E2.

As can be seen from FIG. 1, the second horizontal plane E2 lies above the first horizontal plane E1.

In particular, an associated drive, the associated pressure system 30, a spreader roller, a web separation and transfer device and / or a receiving device for the new empty spool 14 'can be vertically displaced together with the carrier drum 18. In this case, the relevant components can be combined in particular to form a structural unit which can be moved vertically in a guide via at least one actuator. In particular, at least one mechanical or hydraulic actuator can be used.

During the transfer of the carrier drum 18 from the first plane E1 in the second plane E2 of the winding nip 24 can be maintained via a corresponding, preferably horizontal displacement of the winding roll 16. The line force in the winding nip 24 can be adjusted, controlled or regulated via a corresponding, preferably radial displacement and contact pressure of the carrier drum 18. The carrier drum 18 displaced into the second plane E2 is arranged obliquely above the old winding roller 16 remaining in the first plane E1.

In step B, the winding roll 16 is thus controlled away, while the carrier drum 18 is weg- and force controlled.

In step D, the new winding nip 24 'is produced between the carrier drum 18 displaced into the second plane E2 and the new drum 14' provided in this second plane E2 via a displacement of the carrier drum 16 taking place in the second plane E2. In this case, the old reel spool 16 in the first plane E1 is simultaneously displaced horizontally with the carrier drum 18 at the same time. In this case, the carrier drum 18 and the old winding roller 16 can be moved together as far until the new winding nip 24 'is closed.

During the common displacement of carrier drum 18 and old winding roll 16, the line force in the old winding nip 24 can be adjusted, controlled or regulated via a corresponding displacement and contact pressure of the old winding roll 16.

In steps C and D, the carrier drum 18 in the second plane E2 in one direction, here to the left, be displaced by a predetermined distance until the carrier drum 18 is pressed against the spool 14 ', so that in the new winding nip 24th 'sets a predeterminable line force.

In step C, the new empty spool 14 'can be removed from a spool magazine and inserted into a receiving device of the vertically displaceable unit.

In step D, as already mentioned, the carrier drum 18 and the old winding roll 16 jointly moved so far until the new winding nip 24 'between the carrier drum 18 and the new drum 14' is closed. As soon as this new winding gap 24 'is closed, the web change takes place ("winding phase").

In step D, therefore, the carrier drum 18 and the winding roller 16 are moved together, preferably horizontally, until the new winding gap 24 'is closed. In this case, a larger force must be applied by the carrier drum 18 than by the winding roller 16. In addition, the force that can be applied by the carrier drum is greater than or equal to the line force in the new winding gap 24 '.

The material web 12 can now be separated, for example, with the aforementioned web separation device and wound up with its new web beginning on the new spool 14 '("Anwickelphase"). Following that will be the old one Winder 16 removed by removing the old winding nip of the carrier drum 18 (see step E).

When winding the new winding roll 16 'in the second plane E2 (see step E), the line force in the new winding nip 24' can be adjusted, controlled or regulated via a corresponding displacement and contact pressure of the carrying drum 18. The diameter increase of the new winding roll 16 'which occurs in this winding of the new winding roll 16' in the second plane E2 can be compensated for via a corresponding displacement of the carrying drum 18 in the second plane E2.

In step E, the finished winding roll is thus moved away after a change of path in a removal position. The carrier drum 18 is force-controlled to produce the desired line force in the new winding nip 24 ', and the diameter increase of the new winding roll 16' is compensated horizontally via a corresponding horizontal displacement of the carrier drum 18.

After the new winding roll 16 'has been wound on, the carrier drum 18 and the new winding roll 16' are jointly displaced vertically into the first plane E1 while maintaining the new winding nip 24 'formed therebetween (see step F). The except the carrier drum 18 in particular also the associated Anpresssystem 30, a spreader roller, a web separation device and / or a receptacle for the empty beating comprehensive unit is thus lowered again.

Optionally, the carrier drum 18 and the new winding roll 16 'from the second plane E2 can be vertically displaced vertically into the first plane E1 as soon as the carrying drum 18 has returned to its starting position in the course of winding the new winding roll 16' in the second plane E2 she after the Transfer from the first level E1 initially occupies the second level E2.

FIG. 2 shows a schematic diagram, comparable to FIG. 1, of a modified embodiment in which other positions of the new spool 14 'result. The vertical movement or displacement of the new spool 14 'can take place, for example, at an angle to the horizontal of about 60 ° to about 120 ° and preferably from about 85 ° to about 95 °. In FIGS. 1 and 2, like reference numerals are assigned to corresponding parts.
