The new material sheet delivered from the new reel is initiated in the winding device.

Description

The invention relates to a method for changing Tambouren in a reel winder, in which at the end of a winding sequence a web of material dispensing and driven drum is delayed to a stop, then the resting web is severed in the reel winder and then a new, from a new drum discharged material web is introduced into the roll winding device, wherein a beginning of the new material web by means of an auxiliary device in a predetermined width, in particular in full width, is subtracted from the new spool.

Furthermore, the invention relates to a reel winding device for winding a running from a spool material web, which is driven by a prime mover, the reel winding means at least one separating device for severing the resting after the winding sequence material web and an auxiliary device for subsequent insertion of a new, from a new spool having discharged material web in the roll winding device, wherein a beginning of the new material web by means of the auxiliary device in a predetermined width, in particular in full width, is removable from the new spool.

Such a method for changing Tambouren in a reel winding device is for example from the European Patent EP 0 820 946 B1 known.

It is now common practice that the material web donating tambour is slowed down towards the end of the winding sequence in its single unwinding to standstill. Thereafter, the connection between now resting drum and drive is separated and the drum is removed from its unwinding position and thus also from the reel winder. Subsequently, a new, a new web dispensing tambour of the unwinding position is supplied and connected to the drive. Now, the new web must be introduced into the reel winder before it can be started with the winding of the new material web.

This method just described and commonly practiced adheres to the great disadvantage that for changing the reels relatively much time is needed. Also, the individual process steps can be carried out only in succession, which in turn makes negative in the time required for the implementation of the method.

The invention is therefore based on the object, a method and a reel winding device of the types mentioned in such a way that the time required to change the reels noticeably reduced and thus a significant increase in capacity of the reel winder is achieved.

• gegen Ende der Wickelsequenz wird ein Sekundärantrieb in den von einem Primärantrieb angetriebenen Tambour angekuppelt,
• der Primärantrieb wird aus dem Tambour abgekuppelt und vorzugsweise bis zum Stillstand abgebremst,
• zeitgleich, zumindest zeitlich überlappend oder danach wird der von dem Sekundärantrieb angetriebene Tambour von einer Hauptabwickelposition in eine Endabwickelposition gebracht,
• anschließend wird der neue, die neue Materialbahn tragende Tambour in die Hauptabwickelposition gebracht und der Primärantrieb angekuppelt,
• hernach zieht die Hilfseinrichtung den Anfang der neuen Materialbahn in einer vorbestimmten Breite, insbesondere in voller Breite, von dem neuen Tambour ab und verfährt in eine Warteposition für den anstehenden Bahneinzug,
• zeitgleich, zumindest zeitlich überlappend oder danach wird der laufende Tambour mit Hilfe des Sekundärantriebs bis zum Stillstand verzögert,
• danach wird die ruhende Materialbahn in der Rollenwickeleinrichtung durchtrennt,
• anschließend wird eine neue, von einem neuen Tambour abgegebene Materialbahn mittels der Hilfseinrichtung in die Rollenwickeleinrichtung eingeführt und
• nunmehr wird mit dem Wickeln der neuen, von dem neuen Tambour abgegebenen Materialbahn in der Rollenwickeleinrichtung begonnen.

This object according to the invention is achieved in the method mentioned in the introduction by the following method steps:

• Towards the end of the winding sequence, a secondary drive is coupled into the drum driven by a prime mover,
• the prime mover is uncoupled from the drum and preferably decelerated to a standstill,
• at the same time, at least overlapping in time or thereafter, the spool driven by the secondary drive is brought from a main unwinding position to a final unwrapping position,
• then the new, carrying the new material web spool is brought into the main unwinding position and coupled to the prime mover,
• Thereafter, the auxiliary device pulls the beginning of the new material web in a predetermined width, in particular in full width, from the new spool and moves into a waiting position for the upcoming web feed,
• at the same time, at least overlapping in time, or after that, the running drum is delayed to a standstill with the aid of the secondary drive,
• then the resting material web is severed in the roll winding device,
• Subsequently, a new, delivered by a new spool material web is introduced by means of the auxiliary device in the reel winder and
• now is begun with the winding of the new, issued by the new spool material web in the reel winder.

The object of the invention is completely solved in this way.

For the first time, this method according to the invention makes it possible to operate a reel winding device as a result of the method steps and step sequences with noticeably reduced downtimes for changing the reels. Overall, the standstill times of the reel-winding device are therefore reduced, which in turn leads to a significant increase in capacity of the same.

With regard to the achievement of the shortest possible changeover times, it is also advantageous if the secondary drive is coupled in the driven by the primary drive drum towards the end of the winding sequence at full or almost full machine speed. This ensures a consistently high machine speed of the reel winder, wherein the acceleration of the secondary drive can be done separately and in advance.

Thus, the subsequent unwinding of the new web can be done immediately from the Hauptabwickelposition out, driven by the secondary drive spool is preferably brought at full or almost full machine speed of the Hauptabwickelposition in the Endabwickelposition. In this case, the final unwinding position may be situated above, in particular vertically above or in front of, in particular, horizontally in front of the main unwinding position.

For the purpose of reliable replacement of the reels, the web of material resting in the reel winder is preferably severed and subsequently removed. The transection of the stationary material web can be done, for example, by means of a cross-cutting device known to those skilled in the art, which is arranged at a suitable location within the reel winding device. Thus, the severed web is quickly and safely removed from the reel winding device, it is preferably wound by reversing the previous direction of the reel on the spool.

In a further embodiment, the roll winding device can also be designed as a roll cutting device. When producing winding rolls of a so-called mother or jumbo roll, the web is often cut in the same width later desired by the user. For this purpose, a longitudinal cutting device is required so that you get a variety of bobbins from a parent or jumbo roll. The slitting device consists in many cases of two rows of knives, which lie opposite sides of the web. In this case, the material web to be wound is preferably guided by a longitudinal cutting device, wherein the longitudinal cutting device is opened in a suitable manner prior to the passage of the auxiliary device. Likewise, after the passage of the auxiliary device, the longitudinal cutting device is in turn preferably closed and at least one longitudinal cut generated in the new material web before the auxiliary device reaches the winding position. However, this is usually possible without problems.

With regard to the achievement of good winding parameters, it is advantageous if, with the winding of the new material web delivered by the new spool, the primary drive takes over the web tension control. It is self-evident for the expert that the secondary drive is equipped with a web tension control.

So that a simple disposal of the residual material web and thus a simplified empty drum handling is made possible, the drum drive driven by the secondary drive is brought into a descaling position, preferably in the region of the final unwinding position. In this Abschwartposition the remaining, wound on the drum material web is preferably fed to a machine-wide shredder with preferential suction.

Furthermore, the secondary drive having a web tension control is preferably uncoupled from the reel spool after the remaining web of material has traveled, and preferably brought into a waiting position. Among other things, this provides the advantage that the secondary drive is already prepared again for the next change of the tambourines.

In a roller winding device of the type mentioned, the object of the invention is achieved in that a secondary drive for Coupling and for driving the driven by the prime mover drum toward the end of the winding sequence is provided that a first movement means for Bring the driven by the secondary drive spool from a Hauptabwickelposition is provided in a Endabwickelposition, and that a second movement means for Bring the new, the new Material web carrying spool is provided in the main unwinding position.

The object of the invention is completely solved in this way and it results in the aforementioned advantages of the invention.

The Endabwickelposition for the web dispensing tambour is in a preferred embodiment above, in particular vertically above or before, in particular horizontally arranged in front of the main unwinding position. Both position options provide, among other things, the advantages of short movement paths.

Furthermore, the secondary drive for the drum preferably also has a direction of rotation in the unwinding opposite direction of rotation. As a result, a fast and clean removal of the severed material web is made possible by winding on the spool.

With regard to the achievement of good winding parameters, it is advantageous if the primary drive is designed for taking over the web tension control during the main unwinding phase.

Moreover, a scarfing device can be provided in an advantageous manner, which can be fed in a Abschwartposition the remaining, wound on the spool material web. In this case, the Abschwarteinrichtung be a machine-wide shredder with preferential suction. All in all This design option allows easy disposal of the residual material web and thus a simplified empty drum handling.

So that the secondary drive for the next change of drums is quickly prepared again, it can be decoupled from the spool after the remaining material web and preferably in a waiting position can be brought.

The auxiliary device preferably has suction openings and / or clamping means, since both versions best hold the beginning of the material web. In addition, both auxiliary devices are remotely controllable, which means you can operate them from the outside.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings.

In FIGS. 1 to 13, a roller winding device 1 for winding up a material web 2 (6) running away from a drum 3 (7) is shown, in each case in a schematic and partial side view. The material web 2 (6) donating tambour 3 (7) is of a primary drive 4 of known type and Driven operation and stored accordingly in a main position H. The prime mover 4 is designed in particular for taking over the web tension control during the main unwinding phase. Such a reel winding device 1 is for example from the German Offenlegungsschrift DE 37 23 600 A1 The disclosure of which is hereby incorporated by reference in terms of design and mode of operation.

The material web may in particular be a fibrous web, preferably a paper or board web.

From the already mentioned European Patent EP 0 820 946 B1 Furthermore, it is known that the reel winding device 1 at least one separating device, not shown in detail, for severing the material web 2 resting after the end of the winding sequence and an auxiliary device 5 (FIGS. 3 to 5, 10 to 12) for the subsequent insertion of a new one a new drum 7 discharged material web 6 in the roll winding device 1, wherein a beginning 8 of the new material web 6 by means of the auxiliary device 5 in a predetermined width, in particular in full width, from the new spool 7 is removable (Figure 5).

The roller winding device 1 now has a secondary drive 9, which in principle has the same design and operation as the primary drive 4. However, as a rule, the secondary drive 9 has a smaller power than the primary drive 4. In the embodiments shown in FIGS. 1 and 8, the respective primary drive 4 is arranged on the drive side and the respective secondary drive 9 on the non-drive side. The secondary drive 9 also has a train tension control known to the person skilled in the art.

In a first method step is now provided that towards the end of the winding sequence of the secondary drive 9 in the of a primary drive 4th driven drum 3 is coupled. This is indicated symbolically in the schematics which supplement FIGS. 1 and 8.

Subsequently, in the next method step, the primary drive 4 is then uncoupled from the drum 3 and preferably decelerated to a standstill.

In a further method step of the method according to the invention is at the same time, at least temporally overlapping or thereafter, as shown in Figure 2 by a movement arrow P1, driven by the secondary drive 9 Tambour 3 of a first, only schematically indicated moving means 10 at full or almost full machine speed from the main unwinding position H to a final unwinding position E. The Endabwickelposition E is located in the embodiment of Figure 2 above, in particular vertically above the Hauptabwickelposition H. The movement device 10 may be, for example, a lifting device which raises the spool 3 together with the secondary drive 9 on both sides.

In the following step, as shown in Figure 3 by a movement arrow P2, the new, the new material web 6 supporting drum 7 is brought from a second, only schematically indicated movement means 11 in the Hauptabwickelposition H and the prime mover 4 is coupled. The second movement device 11 may, for example, be a displacement device in the form of an actuatable lever pair which moves the tambour 7 together with the wound-up material web 6 evenly and on both sides.

If the second drum 7 has arrived in the main unwinding position H, then in a next method step as shown in FIG. 4 the auxiliary device 5 will pull off the beginning 8 of the new material web 6 in a predetermined width, in particular in full width, from the new drum 7 and in move a waiting position W1 shown in dashed lines for the upcoming web feed. The auxiliary device 5 may have a plurality of suction openings and / or clamping means for the purpose of holding the material web 2. Such an auxiliary device 5 is for example in the not previously published German patent application DE 10 2004 049 720.6 described, whose disclosure in terms of design and operation is hereby made the subject of the present description.

The moving drum 3 is delayed in a further process step at the same time, at least overlapping in time or thereafter with the help of the secondary drive 9 to standstill. Subsequently, the resting material web 2 is severed in the roll winding device 1, wherein the severing of the stationary material web 2 can be done for example by means of a cross-cutting device known in the art, which is arranged at a suitable location within the roll winding device 1. A suitable location can be, for example, immediately before the roll-up of the material web 2. The severed material web 2 is then wound by reversing the previous direction on the spool 3 and thus removed. The secondary drive 9 for the drum 3 thus also has a direction of rotation in the unwinding opposite direction of rotation.

In the next method step, the new material web 6 delivered by the new drum 7 is then introduced into the roll winding device 1 by means of the auxiliary drum 5. If the reel-winding device 1 is designed as a reel-cutting device known to a person skilled in the art, the material web 6 to be wound is guided through a longitudinal cutting device, wherein the longitudinal cutting device is opened prior to the passage of the auxiliary device 5. The longitudinal cutting device is closed again after the passage of the auxiliary device 5. In this case, at least one longitudinal section in the new material web 2 is preferably produced before the auxiliary device 5 reaches the winding position. Such executed as a roller cutter Roller winding device 1 is for example in the already mentioned, but not previously published German patent application DE 10 2004 049 720.6 described, the disclosure of which in terms of design and operation is hereby again made the subject of the present description.

In the final method step, as shown in FIG. 5, the winding of the new material web 6 delivered by the new drum 7 in the roll winding device 1 is now started. In this case, the primary drive 4 preferably takes over the web tension control with immediate effect.

The driven by the secondary drive 9 Tambour 3 is then brought into a preferably located in the range of Endabwickelposition E Abschwartposition A. There, the remaining, wound on the spool 3 material web 2 a scarfing device 12 is supplied. The scarfing device 12 can be, for example, a machine-wide shredder known to the person skilled in the art with preferably suction.

FIGS. 6 and 7 show by way of example two options according to the invention for a deswarming position A together with a scarfing device 12 located in the region of the final unwinding position E.

The Abschwartposition A may be located above the unwinding, for which purpose the spool 3 is moved according to the movement arrow P3 in the Abschwartposition A. The Abschwartposition A can also be equal to the Endabwickelposition E, in which case the Abschwarteinrichtung 12 is moved according to the movement arrow P4 in the Abschwartposition A.

The secondary drive 9 is uncoupled from the spool 3 after the remaining web of material 2 and preferably brought into a waiting position W2. The waiting position W2 of the secondary drive 9 is, for example non-drive side and in alignment of the drive axle of the prime mover 4 (Figure 1).

FIGS. 8 to 13 show a schematic flow diagram of an alternative embodiment of the method according to the invention for changing reels 3, 7 in a reel winding device 1.

In contrast to the method illustrated in FIGS. 1 to 5, in an alternative method step the drum 3 driven by the secondary drive 9 is at full or approximately full machine speed from the main unwinding position H _old (FIG. 8) into the front, in particular horizontally, in front of the main unwinding position H _old Endabwickelposition E _old (Figure 9) brought. The movement of the spool 3 takes place according to the movement arrow P5.

In a further alternative method step, the new, the new material web 6 supporting drum 7 is then brought into the Hauptabwickelposition H _old and the prime mover 4 is coupled in a known manner (Figure 10). The movement of the new spool 7 takes place according to the movement arrow P6. In addition, in a further alternative method step, the auxiliary device 5 is applied to the reel-winding device 1 for the subsequent introduction of the new web 6 delivered by the new spool 7.

The material web 2 is further unwound from the drum 3 and fed to the roll winding device 1 (Figure 11).

In further alternative method steps, the moving drum 3 is then decelerated to standstill with the aid of the secondary drive 9. Alternatively, the moving drum 3 can be brought into a preferably in the range of the final unwinding position E _old Abschwartposition A _old and then delayed by means of the secondary drive 9 to a standstill. Subsequently, the resting web of material 2 in the reel winding device 1, wherein the severing of the stationary material web 2 can be done for example by means of a cross-cutting device known in the art, which is arranged at a suitable location within the reel winding device 1. A suitable location can be, for example, immediately before the roll-up of the material web 2. The severed material web 2 is then wound by reversing the previous direction on the spool 3 and thus removed. The secondary drive 9 for the drum 3 thus also has a direction of rotation in the unwinding opposite direction of rotation. Thereafter, the spool 3 is brought into a preferably in the range of the final unwinding position E _old Abschwartposition A _old . The movement of the spool 3 takes place according to the movement arrow P6. Then the new discharged from the new drum 7 material web 6 is introduced by means of the auxiliary device 5 in the reel winding device 1. Now, the winding of the new, issued by the new spool 7 material web 6 is started in the reel winding device 1. In this case, the primary drive 4 preferably takes over the web tension control with immediate effect (FIG. 12).

In a final process step, the remaining material web 2 wound up on the spool 3 is fed to a scarfing device 12. The scarfing device 12 can be, for example, a machine-wide shredder known to the person skilled in the art with preferably suction. The Abschwartposition A _old can be located above the Endabwickelposition E _old , in which case the Abschwarteinrichtung 12 is moved according to the movement arrow P7 in the Abschwartposition A _old .

The alternative embodiment illustrated in FIGS. 8 to 13 is thus based essentially on the embodiment of the method according to the invention for changing tambours 3, 7 in a roll winding device 1 shown in FIGS. 1 to 5. Obviously just a few distinctive nuances between both embodiments.

In summary, it should be noted that a method and a reel winding device of the aforementioned types are developed such that the time required to change the reels noticeably reduced and thus a significant increase in capacity of the reel winder can be achieved by the invention.
