Definitions

  • the invention relates to a method for introducing a material web into a roll winding device, in which the beginning of the material web is withdrawn by means of an auxiliary device in full width from a supply roll. Furthermore, the invention relates to a reel winding device with an unwinding station, which has at least one position for a supply roll, a take-up station with at least one winding position and an auxiliary device which detects a web of material from the supply roll in the region of the unwinding in full width.
  • a method and a roll winding device of this type are known from EP 0 820 946 B1.
  • the material web after it has been deducted from the supply roll, passed over a cutting device which cuts a tip of the material web.
  • the roll winding device has at least one knife, which is laterally displaceable when pulling the material web transversely to the direction of movement of the material web. In this way it is possible to produce a cut with the knife, which runs at an angle to the direction of movement of the material web.
  • the summit has the advantage that the material web can be handled more easily. But it has several disadvantages. On the one hand, a certain proportion of the material web is lost.
  • the invention has for its object to improve the automation possibilities.
  • This object is achieved in a method of the type mentioned above in that the web is fed in full width of a winding position and the auxiliary device is released in the winding position of the web.
  • the material web is guided by a longitudinal cutting device, wherein the longitudinal cutting device is opened before the passage of the auxiliary device.
  • the longitudinal cutting device When producing bobbins from a mother or jumbo roll, the web is often cut in the same width later desired by the user. For this purpose, the slitter is required. So you get from a parent role a variety of bobbins.
  • the longitudinal cutting device consists in many cases of two rows of knives, which abut from opposite sides of the material web. To allow the passage of the material web under the control of the auxiliary device, now these two rows of blades must be moved far enough apart, and indeed so far that the Auxiliary device fits through. However, this is usually possible without problems.
  • the longitudinal cutting device is closed after the passage of the auxiliary device and generates at least one longitudinal section in the material web before the auxiliary device reaches the winding position.
  • This is another measure to save time and material.
  • one would like to work with the winding of the partial webs i. the winding of the subdivided by longitudinal cutting material web on a plurality of winding rollers, then start when the partial webs are separated from each other at the winding position.
  • the auxiliary device has passed through, then one can keep the "uncut" area very short. For example, if one closes the slitter immediately after passing through the auxiliary, an uncut area of the order of 50 cm to 1 m remains. Only this area must then be conveyed beyond the winding position to start the actual winding process.
  • the auxiliary device After reaching the winding position, the auxiliary device preferably continues to pull the material web until the longitudinal cut reaches the winding position. This achieves that the individual winding rolls are no longer connected.
  • the material web is wound onto the auxiliary device in the region of the winding position until the longitudinal cut reaches the winding position.
  • the material web is held in the area of the winding position, the material web is severed between the winding position and the auxiliary device and the auxiliary device is moved to a disposal position.
  • the disposal position the separated part of the material web, in particular the uncut part, is removed from the auxiliary device, for example unwound, and fed to a pulper.
  • the auxiliary device is then available again for receiving the next material web start.
  • the auxiliary device is moved in one revolution from a receiving position to the winding position and back.
  • the object is achieved in a roll winding device of the type mentioned above in that the auxiliary device from the unwinding station to the winding station in the region of the winding position is movable.
  • a longitudinal cutting device is arranged between the unwinding station and the winding station, wherein the longitudinal cutting device has a cutting state in which it produces at least one longitudinal cut in the continuous material web, and a pass state in which the auxiliary device is movable through the longitudinal cutting device.
  • the longitudinal cutting device has for dividing the material web into a plurality of partial webs, as a rule, two rows of knives arranged on both sides of the material web, two knives always cooperating to produce a longitudinal cut.
  • the knives have practically no clearance in the cutting state or even overlap slightly.
  • the auxiliary device is passed through the longitudinal cutting device, then the auxiliary device needs some space. For this purpose, the knives are moved apart accordingly. This is then the pass state.
  • the longitudinal cutting device comprises two trusses, of which at least one is displaceable relative to the other.
  • the displacement of the trusses it is easily possible to provide the space required, which is necessary to pass the auxiliary device with the attached web through the slitter.
  • the displacement of at least one traverse is usually easier to implement, as a correspondingly large displacement of the knife on this Traverse.
  • the auxiliary device is guided on two transverse to the direction of movement of the web with a predetermined distance from one another arranged trajectories.
  • the trajectories may be formed for example by rails or guides.
  • the movement paths are arranged laterally outside the material web. These trajectories then interfere with the other components of the reel winder not in operation. In particular, one must in the longitudinal cutter take no action to close the slitter despite the presence of the trajectories.
  • the trajectories are located laterally outside the slitter.
  • the trajectories of the auxiliary device are guided in one circulation. Accordingly, the auxiliary device can be returned from the unwinding station to the rewinding station on a first section of the movement paths and from the rewinding station to the unwinding station in a second section. The return of the auxiliary device does not disturb the operation of the reel winder.
  • the movement paths are designed for a two-directional movement.
  • the auxiliary means can be returned to the same section of trajectories from the rewinding station to the unwinding station where it has taken the reverse route of insertion.
  • this has the disadvantage that the slitter can start a little later with their work, because they must remain open until the auxiliary device has been moved back. With limited space you can take this disadvantage but in purchasing.
  • a transport device is guided along at least one movement path. It is therefore not necessary that the auxiliary device itself has a drive which moves with the auxiliary device. Rather, you can provide a stationary drive, which then acts on the transport device.
  • the transport device may be formed, for example, as a chain, belt or rope and pull the auxiliary device along the trajectories.
  • a transverse cutting device which acts on the material web between the auxiliary device and the winding position.
  • the material web can thus be severed between the winding position and the auxiliary device. This simplifies the listing of the material web. It is not necessary to clear the web of material from the auxiliary device first. Accordingly, one need not necessarily make sure that the beginning of the material web is not damaged when being detected by the auxiliary device. A small portion of the web can be tolerated as a loss as long as it is the portion required by the auxiliary web support.
  • the unwinding station has a preparation position, below which a pulper opening is arranged, wherein the auxiliary device is movable through a region between the preparation position and the pulper opening.
  • the unwinding station usually has an unwinding position in which the parent roll is when it is unwound.
  • a preparation position In order to allow the smoothest possible change between two parent rolls, one sees in the unwinding at least one other place, namely a preparation position.
  • this preparatory position will be a new mother role prepared, ie outer layers, which may be damaged, are unwound and it is produced as straight as possible leading edge of the web, which extends at an angle of approximately 90 ° to the direction of movement of the web. This process is also referred to as "stalling".
  • a cross cutter is arranged in the area. This facilitates the production of a clean material web start. If the auxiliary device has detected the material web, then the cross cutter comes into action and separates the material web below the auxiliary device. The separated part falls into the pulper. The auxiliary device then holds the beginning of the material web.
  • the cross cutter preferably has a separating region which can be displaced in the direction of movement of the material web.
  • the mother or jumbo rolls have in some Cases are not always the same diameter. If the mother roll is always locked in the same preparation position, then the beginning of the web also depends on different positions in the direction of movement down. This is usually no problem for the auxiliary device because it can be displaced in the direction of movement anyway and therefore can absorb the small positional differences. If the slitter is also displaceable, then it can handle these positional differences as well.
  • the auxiliary device preferably has suction openings and / or clamping means. Both serve to hold the beginning of the web. Suction openings hold the material web with negative pressure. It is of course necessary in this case to ensure that air can be sucked out of the auxiliary device or at least out of the suction openings.
  • clamping means you only need to ensure that these clamping means can detect the beginning of the web and hold. Both retainers are remotely controllable, i. you can serve them from the outside.
  • an activation device acting on the auxiliary device is arranged in the region of the unwinding station. You can then activate the auxiliary device at the moment where they should take the web. If the auxiliary device holds the material web, for example by means of suction openings, then one can generate a negative pressure in the auxiliary device with the aid of the activation device. If the material web is held by means of clamping means, then the activation means press the clamping means. As a rule, it is sufficient if the activation device acts on the auxiliary device only at the beginning of the holding. So you can leave the activation device so stationary, under certain circumstances, small movement possibilities are provided to take into account the different diameters of the parent roles. However, it is not necessary that the activation device is moved from the unwinding station to the rewinding station and back. This facilitates the leadership.
  • the activation device is designed as a rotary drive, which can be brought into operative connection with the auxiliary device.
  • the rotary drive thus rotates the auxiliary device, so that the auxiliary device winds up the beginning of the material web.
  • the material web to the auxiliary device holds, as long as a certain voltage is present. It is then possible, for example, to switch off the negative pressure at the suction openings or reduce the force of the clamping means.
  • the operative connection between the rotary drive and the auxiliary device can be generated via an engageable coupling, so that the rotary drive does not have to join the entire movement of the auxiliary device.
  • a rotary drive which can be brought into operative connection with the auxiliary device is arranged in the region of the winding position.
  • this rotary drive can be coupled after reaching the winding position with the auxiliary device, for example by a coupling.
  • the rotary drive allows the auxiliary device to be turned further and to wind up a region of the material web which is not cut by the longitudinal cutting device. This makes it possible to pull the material web without further displacement of the auxiliary device so far into the winding position that only already cut partial webs are present at the winding position and they can be wound up into separate winding rolls.
  • a splicing station is arranged between the unwinding station and the longitudinal cutting device.
  • a splicing station can for example produce a so-called “buttsplice", as described in DE 199 23 097 A1.
  • the splice station makes it possible to dispense with the re-insertion or threading of the web into the reel winder when changing from parent rolls. It simply connects the beginning of a new mother role with the end of a near-completion mother role.
  • the auxiliary device is movable in a space below a floor level, on which the unwinding station and the winding station are arranged.
  • the movement of the auxiliary device takes place in the "basement”, while the unwinding station and the winding station are arranged in the "ground floor”.
  • Such an arrangement increases safety. The risk that operators who are in the area of the unwinding station and the winding station, come into contact with the auxiliary device and injure himself, is relatively low.
  • Fig. 1 shows a schematic representation of a roll winding device 1 with an unwinding station 2 and a winding station 3. Between the unwinding station 2 and the winding station 3, a longitudinal cutting device 4 is arranged.
  • an unwinding position 5 is provided.
  • a master roll 8 is wound, of which a remainder is still visible in Fig. 1.
  • a web 9 is withdrawn.
  • This material web 9 is cut in the longitudinal cutting device 4 into a plurality of sub-webs and wound in the winding station 3 to a plurality of winding rollers 10, of which in Fig. 1, only one is recognizable, because these reels 10 are in a direction perpendicular to the plane behind the other.
  • the unwinding 6 is suitable for higher speeds.
  • the material web 9 can be removed at a speed of 2000 to 3000 m / min.
  • the winding rollers 10 rest on two support rollers 11, 12, of which at least one is driven.
  • a loading roller 13 may be provided to control the winding process.
  • a back-up roll winder in which the winding rollers 10 are held centrally and bear against a support or contact roller.
  • the unwinding station 2 also has a preparation position 14, in which a further reel 15 with a new master reel 16 is kept ready.
  • the preparation position has a preparation bearing 17, which also allows a rotation of the main cylinder 15, but is less expensive, because the necessary rotation speeds are much lower.
  • the preparation bearing 17 and the unwinding bearing 6 are interconnected by a track 18 on which the spool 15 in the preparation position 14 to the unwinding position 5 can roll when a reel change is required.
  • the mother roll 16 is prepared. As a rule, some layers of the material web are unwound and disposed of in preparation.
  • a pulper opening 19 is provided which is arranged below the preparation position 14 in such a way that the material web 9 hanging down under the effect of gravity impinges on the pulper opening 19. Since the parent roll 16 does not always have the same radius, the position of the drooping web 9 will move slightly. However, the pulper opening 19 is so large that it can catch the falling web of material.
  • a hopper 20 may be additionally provided.
  • the roll winding device 1 For insertion, the roll winding device 1 an auxiliary device 21, which is shown in Fig. 1 at different positions. In different positions, the auxiliary device 21 is provided with small letters (a, b, c) for distinction.

  • the trajectory is realized by rails or guides, which are arranged on both sides of the web 9 outside its width.
  • a chain, a belt or a rope can be performed, these facilities in not shown in more detail by a common drive, so that the auxiliary device 21 can be performed in an orientation perpendicular to the direction of movement of the web 9 from the unwinding station 2 to the winding station 3.
  • the auxiliary device 21 is now moved from the left (relative to the illustration of FIG. 1) to the under the action of gravity vertically down hanging web 9 and attached to the web.
  • the auxiliary device 21 may have suction openings in a manner not shown. If a vacuum is generated at the suction openings, then the auxiliary device 21 holds the material web 9 firmly. Instead of the suction openings and clamping means may be provided which hold the web 9.
  • the auxiliary device 21 it is also possible that one turns the auxiliary device 21 about an axis (perpendicular to the plane) so that it winds the hanging material web 9 with a few turns. As long as a sufficient tension in the material web 9 is maintained, the material web 9 holds firmly on the auxiliary device 21.
  • the auxiliary device 21 can be connected to a stationary and not shown rotary drive.
  • a transverse cutting device 23 can be actuated, which separates a superfluous portion 24 of the material web 9. This section 24 then also falls into the pulper opening 19.
  • the transverse cutting device 23 is displaceable in the direction of a double arrow 25 to differences in the radius of the parent roll 16th catch, which are reflected in different positions of the drooping web 9.
  • a change in the position of the material web 9 is not critical, because it can be moved along the path of movement 22 anyway.
  • the auxiliary device 21 is then displaced along the movement path 22 to the winding station 3, thereby leading the material web 9 by a plurality of deflection rollers 26 to the winding station 3.
  • the movement path 22 keeps sufficient distance to the deflection rollers 26-29, so that the material web 9, the rear the auxiliary device 21 is pulled, the deflection rollers 26 so wraps around, as is required later in the operation.
  • the auxiliary device 21 does not come into collision with the deflection rollers 26-29. Simultaneously with the guiding of the beginning of the material web, the new master roll 16 can be displaced into the unwinding position 5.
  • the cutting device has an upper cross member 30 with upper blades 31 and an lower cross member 32 with lower blades 33.
  • the lower crosshead 32 is displaced in the direction of a double arrow 34, so that the lower blade 33 can be displaced on the cutting position shown in phantom in a continuous position shown by solid lines.
  • the longitudinal cutting device 4 thus has a cutting state in which the material web 9 can be cut into a plurality of partial webs, and a continuous state in which the upper blade 31 and lower blade 33 have a distance from each other which is so great that the auxiliary device 21 between the outer blade easily 31 and the lower blade 33 can be driven through.
  • the longitudinal cutting device 4 is closed again, so that the longitudinal sections begin at a relatively short distance from the auxiliary device 21. This distance can be 0.5 to 1 m.

  • the auxiliary device 21c is then further rotated until the longitudinal cuts generated by the longitudinal cutting device 4 arrive at the support roller 12. Thereafter, a cross cutter 35 comes into action, which cuts through the material web 9 between the auxiliary device 21 c and the support roller 12. Once the web 9 has arrived at the support roller 12, it is in a so-called "winding position".
