Definitions
- the invention relates to a device for the continuous winding of a fibrous web, in particular paper, for example tissue web, wherein the fibrous web via a support drum, which is mounted at one end on a vertical rocker arm out, and subsequently wound on a winding device and the force is measured between the rocker arm and a fixed counterpart via a force measuring device, wherein the rocker arm against the force measuring device via a clamping element can be tensioned.
- the contact pressure in the nip between the drum and the reel drum can be measured.
- Such a device is already in the AT 411 590 B (Andritz AG). Also here is in each case a force-measuring device for determining the contact pressure in the nip directly between the respective rocker arm and a fixed counterpart of Textilmaschinenstuhlung.
- Each force measuring device is preloaded against the respective rocker arm via clamping elements before operation. This bias is necessary because otherwise vibrations and vibrations of the carrier drum distort the measurement result.
- clamping elements press the rocker arm against the force measuring devices, thereby a permanent contact between the rocker arm and force measuring device can be ensured and it is supplied a continuous signal for a control.
- the clamping elements in the AT 411 590 B are either mechanically (eg via springs or spring assemblies) or hydraulically or pneumatically operated and tighten the rocker arm always with a constant force against the respective force measuring device.
- the force measuring devices After clamping the rocker arm against the force measuring devices, the force measuring devices are calibrated to nip force 0.
- a preselected nip force is then transmitted via the paper roll to the carrier drum via the hydraulic cylinders (or pneumatic cylinders) of the primary and secondary arms.
- These Force is then measured by the force measuring devices and the measurement result used to control the hydraulic cylinders of the primary and secondary arms.
- the bias of the force measuring device to a constant value before operation has the disadvantage that this bias decreases with time and due to vibrations.
- the aim of the invention is now to disclose a device which eliminates the disadvantages mentioned, thereby a good controllability is given during the winding process even at very low contact pressures.
- the invention is therefore characterized in that the clamping force for the voltage of the rocker arm against the force measuring device via the clamping element in the winding operation is adjustable.
- a bias of the force measuring device during assembly is no longer required.
- the installation of a force measuring device that requires no bias is much easier and faster.
- the clamping force of the rocker arm against the load cell can be adjusted or corrected at any time become.
- the optimum clamping force can be selected for a particular fiber type. For different fiber types, namely, a different nip force may be required and it makes sense if the clamping force is adjusted accordingly. Even operation without clamping force is conceivable. It is of course also conceivable that the clamping force is changed continuously during the winding process of a spool.
- the clamping element is an adjustable hydraulic cylinder.
- About the pressure in the hydraulic cylinder can then be adjusted during operation in a particularly simple manner, the clamping force.
- the hydraulic cylinder is for this purpose connected to a hydraulic line with a corresponding control device.
- the clamping element can be formed by an adjustable pneumatic cylinder.
- the force measuring device is mounted in a recess of the rocker arm and connected via a connecting element with the fixed counterpart. By placing the force measuring device in the rocker arm, this is protected from harmful environmental influences such as dust or sudden temperature fluctuations.
- the force measuring device can also be arranged between the rocker arm and the fixed counterpart.
- the rocker arm can thereby be made simpler and the assembly or the change of the force measuring device is simplified.
- the bearing of the carrier drum is arranged on the oscillating lever within a bearing for a primary arm and is decoupled from the primary arm bearing.
- the storage of the carrier drum and the storage of the primary arm are largely in an axis and in a plane, caused by the nip force forces can be better absorbed by the machine frame.
- Fig. 1 shows an inventive device for winding a fibrous web 1.
- the carrier drum 2 is mounted in each case at one end 3 on a respective vertical rocker arm 4 through the bearing 11.
- the rocker arm 4 has in the present example at its lower end on the sides of two recesses 19, whereby a weakening 17 of the rocker arm 4 is formed. This weakening 17 allows the oscillating movement of the oscillating lever 4.
- the oscillation direction of the oscillating lever 4 is indicated by the arrow 20.
- the fibrous web 1 is wound after the carrier drum 2 in a winding device 5 on a winding tube 15 to a paper coil 16.
- the winding tube 15 is inserted on a winding shaft 23, which is guided at both ends by secondary arms 26.
- a nip 24 is formed between the carrier drum 2 and the paper roll 16.
- the contact force of the paper roll 16 or the winding shaft 23 against the carrier drum 4 must be accurately measured or regulated in winding operation.
- the regulation of the contact force in the nip 24 and the position control of the secondary arms 26 via hydraulic cylinder 25.
- the measurement of the contact pressure in nip 24 via two force measuring devices 7, which are each arranged between the two rocker arms 4 and a fixed counterpart 6.
- the fixed counterpart 6 is part of the paper machine chair or it is firmly connected to the Textilmaschinenstuhlung.
- the detected measured value signals control the contact force of the two hydraulic cylinders 25, so that it is ensured that an absolute parallel operation of the secondary arms 26 on the driver side FS and drive side TS and a preselected Nipkraftverlauf (constant or variable) is secured throughout the winding process.
- each clamping elements 8 are provided according to the invention, the clamping force of these clamping elements 8 is adjustable.
- these can be adjustable hydraulic cylinders or adjustable pneumatic cylinders act.
- the chip elements 8 are connected via the line 18 to a corresponding control device (not shown).
- Fig. 1 the clamping elements 8 are arranged directly under the force measuring device 7, ie on the side of the carrier drum 2, where the fibrous web 1 runs onto the carrier drum 2.
- the clamping force is caused by a contraction of the clamping elements 8.
- the clamping elements 8 can also be arranged on the side of the carrier drum 2, at which the fibrous web 1 runs off from the carrier drum 2, ie on the nip side. This is in Fig. 2 shown. The clamping force is then generated by expanding the clamping elements 8.
- Fig. 3 shows a detailed view of the rocker arm 4 and illustrates a further embodiment of the invention.
- the force measuring devices 7 are each housed in a recess 9 of the rocker arm 4 and fixed to the rocker arm 4.
- the rocker arm 4 has a bore 21 through which a connecting element 10 can be guided from the outside into the recess 9.
- the connecting element 10 is connected at one end to the force measuring device 7 and at the other end to a fixed counterpart 6 of the paper machine chair.
- the diameter of the bore 21 should be so large that the connecting element 10 can be easily passed through without touching the rocker arm.
- a force between rocker arm 4 and fixed counterpart 6 or connecting element 10 can also be measured via the force measuring device 7.
- the bias of the force measuring device 7 is also set here via an adjustable clamping element 8.
- Fig. 4 shows a support drum bearing 11 inside a Primärarmlagerung 12, 13 in the machine direction.
- the winding shaft 23 with the attached winding tube 15 is here still in the primary arm 14 and not in the secondary arm 26, as shown in the Fig. 1 and 2 is shown.
- the ends 3 of the carrier drum 2 are each mounted on the rocker arm 4, this bearing 11 is disposed within a bearing 12, 13 for the primary arm 14 and decoupled from the Primärarmlagerung 12, 13.
- the bearing 11 of the carrier drum 2 and the bearing 12, 13 of the primary arm 14 are largely in an axis and in a plane, caused by the nip force forces can be better absorbed by the machine frame.
- the Primärarmlagerung 12 in this case has an opening 22 through which the end 3 of the carrier drum 2 and the carrier drum shaft is passed.
- the opening 22 must be so large that, despite the slight oscillating movement of the carrier drum 2, the carrier drum shaft can not touch the Primärarmlagerung 12.
- the rocker arm 4 is in this embodiment within the Primärarmstuhlung, as is the force measuring device 7 and the clamping element. 8
- Winding devices with primary and secondary arms are well known, as well as the running therein winding, so here only to the already mentioned AT 411590 is referenced.
Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum kontinuierlichen Aufwickeln einer Faserstoffbahn, insbesondere Papier-, beispielsweise Tissuebahn, wobei die Faserstoffbahn über eine Tragtrommel, die jeweils an einem Ende auf einem vertikalen Schwinghebel gelagert ist, geführt und in weiterer Folge auf einer Wickeleinrichtung aufgewickelt wird und die Kraft zwischen dem Schwinghebel und einem feststehenden Gegenstück über eine Kraftmesseinrichtung gemessen wird, wobei der Schwinghebel gegen die Kraftmesseinrichtung über ein Spannelement spannbar ist. Über diese Kraftmessung am Schwinghebel kann die Anpresskraft im Nip zwischen Tambour und Tragtrommel gemessen werden.The invention relates to a device for the continuous winding of a fibrous web, in particular paper, for example tissue web, wherein the fibrous web via a support drum, which is mounted at one end on a vertical rocker arm out, and subsequently wound on a winding device and the force is measured between the rocker arm and a fixed counterpart via a force measuring device, wherein the rocker arm against the force measuring device via a clamping element can be tensioned. About this force measurement on the rocker arm, the contact pressure in the nip between the drum and the reel drum can be measured.
Eine derartige Vorrichtung ist bereits in der
Die Vorspannung der Kraftmesseinrichtung auf einen konstanten Wert vor dem Betrieb hat den Nachteil, dass diese Vorspannung mit der Zeit und aufgrund von Vibrationen nachlässt. Dadurch ist keine genaue Nipkraftmessung mehr möglich. Die Vorspannung der Kraftmesseinrichtung muss daher von Zeit zu Zeit überprüft und nachgestellt werden, dies ist jedoch nur bei einem Stillstand der Anlage möglich. Die Spannelemente sind außerdem schwer erreichbar, wodurch eine Nachstellung der Vorspannung sehr umständlich ist. Darüber hinaus können mechanische Spannelemente nur relativ ungenau vorgespannt werden.
Ein weiteres Problem sind die während des Betriebes durch Wärme verursachten Längenänderungen der Befestigungselemente für die Kraftmesseinrichtung und die Spannelemente. Auch dadurch ändert sich die Vorspannung im Betrieb und es kommt zu Schwankungen der Messwerte.Such a device is already in the
The bias of the force measuring device to a constant value before operation has the disadvantage that this bias decreases with time and due to vibrations. As a result, accurate nip force measurement is no longer possible. The bias of the force measuring device must therefore be checked from time to time and readjusted, but this is possible only when the system is at a standstill. The clamping elements are also difficult to reach, making an adjustment of the bias is very cumbersome. In addition, mechanical clamping elements can only be biased relatively inaccurate.
Another problem is caused by heat during operation length changes of the fasteners for the force measuring device and the clamping elements. This also changes the bias voltage during operation and results in fluctuations in the measured values.
Ziel der Erfindung ist es nun, eine Vorrichtung zu offenbaren, die die angeführten Nachteile ausräumt, dadurch ist auch bei sehr kleinen Anpressdrücken eine gute Regelbarkeit während des Aufwickelvorgangs gegeben.The aim of the invention is now to disclose a device which eliminates the disadvantages mentioned, thereby a good controllability is given during the winding process even at very low contact pressures.
Die Erfindung ist daher dadurch gekennzeichnet, dass die Spannkraft zur Spannung des Schwinghebels gegen die Kraftmesseinrichtung über das Spannelement im Wickelbetrieb einstellbar ist. Somit ist eine Vorspannung der Kraftmesseinrichtung bei der Montage nicht mehr erforderlich. Die Installation einer Kraftmesseinrichtung, die keine Vorspannung benötigt ist erheblich einfacher und schneller. Die Spannkraft des Schwinghebels gegen die Kraftmessdose kann jederzeit angepasst bzw. korrigiert werden. Außerdem kann für einen jeweiligen Faserstofftyp die optimale Spannkraft gewählt werden. Für unterschiedliche Faserstofftypen kann nämlich eine unterschiedliche Nipkraft erforderlich sein und es ist sinnvoll, wenn die Spannkraft entsprechend angepasst wird. Auch ein Betrieb ohne Spannkraft ist denkbar.
Es ist natürlich auch denkbar, dass die Spannkraft während des Aufwickelvorganges eines Tambours kontinuierlich geändert wird.The invention is therefore characterized in that the clamping force for the voltage of the rocker arm against the force measuring device via the clamping element in the winding operation is adjustable. Thus, a bias of the force measuring device during assembly is no longer required. The installation of a force measuring device that requires no bias is much easier and faster. The clamping force of the rocker arm against the load cell can be adjusted or corrected at any time become. In addition, the optimum clamping force can be selected for a particular fiber type. For different fiber types, namely, a different nip force may be required and it makes sense if the clamping force is adjusted accordingly. Even operation without clamping force is conceivable.
It is of course also conceivable that the clamping force is changed continuously during the winding process of a spool.
In einer vorteilhaften Ausführungsform der Erfindung ist das Spannelement ein einstellbarer Hydraulikzylinder. Über den Druck im Hydraulikzylinder kann dann auf besonders einfache Weise die Spannkraft auch während des Betriebes eingestellt werden. Der Hydraulikzylinder ist dafür mit einer Hydraulikleitung mit einer entsprechenden Steuereinrichtung verbunden.In an advantageous embodiment of the invention, the clamping element is an adjustable hydraulic cylinder. About the pressure in the hydraulic cylinder can then be adjusted during operation in a particularly simple manner, the clamping force. The hydraulic cylinder is for this purpose connected to a hydraulic line with a corresponding control device.
Ebenso kann das Spannelement durch einen einstellbaren Pneumatikzylinder gebildet werden.Likewise, the clamping element can be formed by an adjustable pneumatic cylinder.
In einer weiteren Ausführungsform ist die Kraftmesseseinrichtung in einer Ausnehmung des Schwinghebels befestigt und über ein Verbindungselement mit dem feststehenden Gegenstück verbunden. Durch die Unterbringung der Kraftmesseinrichtung im Schwinghebel ist diese vor schädlichen Umgebungseinflüssen wie beispielsweise Staub oder plötzliche Temperaturschwankungen geschützt.In another embodiment, the force measuring device is mounted in a recess of the rocker arm and connected via a connecting element with the fixed counterpart. By placing the force measuring device in the rocker arm, this is protected from harmful environmental influences such as dust or sudden temperature fluctuations.
Die Kraftmesseinrichtung kann aber auch zwischen dem Schwinghebel und dem feststehenden Gegenstück angeordnet sein. Der Schwinghebel kann dadurch einfacher ausgeführt sein und die Montage bzw. der Wechsel der Kraftmesseinrichtung wird vereinfacht.However, the force measuring device can also be arranged between the rocker arm and the fixed counterpart. The rocker arm can thereby be made simpler and the assembly or the change of the force measuring device is simplified.
Es ist günstig, wenn die Lagerung der Tragtrommel auf dem Schwinghebel innerhalb einer Lagerung für einen Primärarm angeordnet und von der Primärarmlagerung entkoppelt ist. Dadurch liegen die Lagerung der Tragtrommel und die Lagerung des Primärarms weitestgehend in einer Achse und in einer Ebene, durch die Nipkraft hervorgerufen Kräfte können so besser von dem Maschinenrahmen aufgenommen werden.It is favorable if the bearing of the carrier drum is arranged on the oscillating lever within a bearing for a primary arm and is decoupled from the primary arm bearing. As a result, the storage of the carrier drum and the storage of the primary arm are largely in an axis and in a plane, caused by the nip force forces can be better absorbed by the machine frame.

Die Faserstoffbahn 1 wird nach der Tragtrommel 2 in einer Wickeleinrichtung 5 auf einer Wickelhülse 15 zu einem Papierwickel 16 aufgewickelt. Die Wickelhülse 15 steckt auf einer Wickelwelle 23, die an beiden Enden durch Sekundärarme 26 geführt wird.
Zwischen der Tragtrommel 2 und dem Papierwickel 16 wird ein Nip 24 gebildet. Die Anpresskraft des Papierwickels 16 bzw. der Wickelwelle 23 gegen die Tragtrommel 4 muss im Wickelbetrieb genau gemessen bzw. geregelt werden. Die Regelung der Anpresskraft im Nip 24 und die Positionssteuerung der Sekundärarme 26 erfolgt über Hydraulikzylinder 25. Die Messung der Anpresskraft im Nip 24 erfolgt über zwei Kraftmesseinrichtungen 7, die jeweils zwischen den beiden Schwingehebeln 4 und einem feststehende Gegenstück 6 angeordnet sind. Das feststehende Gegenstück 6 ist ein Teil der Papiermaschinenstuhlung bzw. ist es fest mit der Papiermaschinenstuhlung verbunden.
Die erfassten Messwertsignale steuern die Anpresskraft der beiden Hydraulikzylinder 25, sodass dafür gesorgt ist, dass ein absoluter Parallellauf der Sekundärarme 26 auf Führerseite FS und Triebseite TS sowie ein vorgewählter Nipkraftverlauf (konstant oder veränderlich) über den gesamten Wickelvorgang gesichert ist.The fibrous web 1 is wound after the
