Definitions
- the invention relates to a method for winding a material web, in particular paper, cardboard or tissue web, on a spool, wherein the web fed to the spool via a carrier drum and between the carrier drum and the spool or the winding to be formed thereon a winding nip and in this a line force is generated.
- the invention relates to a suitable for carrying out this method winding device according to the preamble of claim 6 and a system for driving the spool in such a winding device.
- the transfer from a first center drive or primary center lift to a second center drive or secondary center drive can have a negative effect on the torque curve and thus on the winding structure.
- the line force generated in the winding nip is influenced by the drum weight, which leads to a displacement of the primary layers, a corresponding loss of volume and a correspondingly higher rejects.
- the Tambour bebiegung line force deviations in the transverse direction If the drum weight is compensated, for example, by a force attack on the edge in the primary winding, the tambour bend line results in a higher line force in the machine center.
- a reverse effect occurs.
- a line force peak occurs, through which the primary layers can be pushed, which in turn leads to a corresponding loss of volume and a higher rejection.
- a respective new or empty bambour can only be inserted if the full tambour already has a correspondingly large diameter.
- the wound drum must be guided away from the carrier drum, which means that a free winding is required or the web must be re-listed.
- the real reason for a center drive is to wind the web with as little line force as possible to maintain the volume. Due to the unfavorable effective direction of the line force, the advantage of the center drive is mostly nullified in the present case.

It is especially ensured that the position of the main cylinder, that is in particular the vertical position relative to the carrier drum, remains constant over the entire winding process and no reversal of the drum bending line occurs and self-weight effects are excluded on the line force. Correspondingly, the line force is kept constant across the machine (cross machine direction, CD) and over the winding diameter. Since the entire winding structure takes place with only one Anpresssystem, there is no power transfer. Since the entire winding structure is done with only one center drive system or center drive, also eliminates the usual torque transfer.

- the Anpressschlittensection 24, 24 'with lowered guide slide 42, 42' under the active drum through in the direction of the carrier drum in the Tamboureinlegeposition be moved.
- the guide carriages are lifted into the working position by means of the hydraulic cylinders or hydraulic cylinder / piston arrangements 50, 50 ', in which they are ready to receive the next drum.
- the winding 18 When the winding 18 has reached the desired diameter, it is moved away from the carrying drum by a predeterminable amount and continues to be wound there centered. During this time, a new spool, which is already in waiting position on the carrier drum in the Tambourlift, inserted into the waiting guide slide pair 42, 42 ', accelerated with the center drive 28 to machine speed and applied to the carrier drum, as already in connection with the previous drum was described. In this process, the web slides for a short time on the not yet rotating drum (bowing).
- the transfer of the material web to the new drum (turn-up) is carried out as described above.
- the finished winding is now braked by the center drive 26, lowered by lowering the guide carriage 40, 40 'on the rails 82 and released.
- the winding now runs on the Tambourlagern on the inclined rails 82 to the stopper 84th
- Tambourlift is equipped with a Tambourstarter to the tambour before insertion into the guide slide on machine speed - -
- alternative drives of the contact carriages can comprise, for example, toothed belts instead of drive chains, spindle drives with transverse shaft and / or a system with rack and single drive on each carriage (electronic synchronization).
- winding structure may also be advantageous to perform the winding structure not force-controlled, but path-controlled, for example, with a defined carriage path per number of winding or material web layers.
- the guide carriages can only serve to guide the drums, in which case they do not carry their weight.
- the tambourines are instead carried by rails, which then extend to the carrier drum. This brings with it the advantage of a largely symmetrical loading of the drum bearings.
- the sensitivity of the control can be influenced. In a path-controlled winding structure, this does not matter.
- the center drives can also be realized as conventional drives mounted independently of the drive carriages.
- a pressing element 90 in particular a pressure roller, is provided in the present embodiment, which is applied to the winding 18 - -
- Figure 4 shows a schematic partial representation of an exemplary embodiment of a system 86 for driving a drum 14 in a winding device, in which a material web, in particular paper, board or tissue web is wound on the spool 14, the web to the spool 14 via a carrier drum can be supplied and a winding nip is formed between the carrier drum and the spool 14 and the winding to be formed thereon.
- a material web in particular paper, board or tissue web
- the drive system 26 comprises at least one center drive 26; 28, which has a rotor provided with an electric motor, coaxial with the drum 14 in association with an axial end portion of the main cylinder 14 is positionable and by moving the center drive in the axial direction of the main cylinder 14 and / or by a relative movement between a rotary drive connection of the center drive 26; 28 and the rotor without gear directly to the spool 14 or a rotary drive connection 32 associated therewith can be coupled.
- a center drive 26; 28 which has a rotor provided with an electric motor, coaxial with the drum 14 in association with an axial end portion of the main cylinder 14 is positionable and by moving the center drive in the axial direction of the main cylinder 14 and / or by a relative movement between a rotary drive connection of the center drive 26; 28 and the rotor without gear directly to the spool 14 or a rotary drive connection 32 associated therewith can be coupled.
- the center drive 26; 28 can with a contact carriage 22, 22 '; 24, 24 'be combined, via which the spool 14 and the winding to be formed thereon can be pressed against the support roller.
- the center drive 26; 28 may be combined with a secondary carriage assigned to a secondary winding area or with a primary carriage assigned to a primary winding area.
- the rotary drive connection associated with the spool 14 may comprise a drive coupling or bell.
- the rotary drive connection 30 of the center drive 26; 28 may in particular comprise a drive train. - -
- the rotor of the center drive comprises, for example, a hollow motor shaft.
- the center drive 26 For example, be coupled by a relative movement between the drive train and the hollow shaft motor with the spool 14 and the associated rotary drive terminal 32.
- the two center drives arranged on different sides can have a different engine characteristic.
- one of the two center drives for example, a relatively smaller torque at relatively higher speeds for a predetermined lower winding diameter range and the other center drive generate a relatively larger torque at relatively lower speeds for a predetermined upper winding diameter range.
- At least one center drive 26 is preferred; 28 associated with a secondary winding area.
- at least one center drive may also be associated with a primary winding area. In this case, for example, such an embodiment is conceivable in which both a primary winding area and a secondary winding area are each assigned at least one center drive.
- the center drives 26; 28 can thus each be again provided in the manner of a "Voith Drive” center.
- FIG. 4 again shows a chair 38 and linear roller guides 72, via which a respective center drive 26; 28 is movable in the transverse direction to allow engagement or disengagement of, for example, a drive train comprehensive rotary drive connection.
- This can be assigned to the center drive rotary drive connection 30th - -
- the center drive 26; 28 may be arranged on a motor slide 88, which is correspondingly movable in the transverse direction via the slide or linear roller guide 72.
- the drive system 36 can be used with particular advantage, in particular also in the winding device 10 according to the invention.
- the center drives of the winding device according to the invention and of the drive system according to the invention are, as already stated, preferably designed as a "Voith Drive” center elevation.
