  • the invention relates to a method for threading a material web into a rewinder, in which the start of the material web is drawn off a supply roll at full width by means of an auxiliary device. Furthermore, the invention relates to a rewinder having an unwind station which has at least one position for a supply roll, a winding station having at least one winding position and an auxiliary device which grips a material web from the supply roll at full width in the region of the unwind station.
  • a method and a rewinder of this type are disclosed by EP 0 820 946 B1.
  • the material web after it has been drawn off the supply roll, is led over a cutting device which cuts a point from the material web.
  • the rewinder has at least one knife which, as the material web is drawn through, can be displaced laterally transversely with respect to the direction of movement of the material web. In this way, by using the knife, it is possible to produce a cut which runs at an angle to the direction of movement of the material web.
  • the point has the advantage that the material web can be handled more easily.
  • it has a number of disadvantages. Firstly, a certain proportion of material web is lost.
  • the present invention improves automation possibilities.
  • the instant invention provides a material web fed to a winding position at full width and an auxiliary device being released from the material web in the region of the winding position.
  • the auxiliary device can be controlled automatically. Since the material web is always present at its full width, sensors which determine whether the width has been reached can be dispensed with. In addition, monitoring by an operator can be ensured substantially more easily.
  • the material web is preferably led through a slitter, the slitter being opened before the passage of the auxiliary device.
  • the material web is often cut at the same time into the width subsequently required by the user.
  • the slitter is necessary for this purpose. A large number of wound rolls are therefore obtained from a parent reel.
  • the slitter in many cases comprises two rows of knives, which bear on the material web from mutually opposite sides. In order to permit the material web to pass through under the control of the auxiliary device, these two rows of knives now have to be moved apart sufficiently for the auxiliary device to pass through. However, this is generally possible without difficulty.
  • the slitter is preferably closed after the passage of the auxiliary device and produces at least one longitudinal cut in the material web before the auxiliary device reaches the winding position. This is another measure for saving time and material. As a rule, it is wished to start winding the part webs, that is to say the winding of the material web subdivided by slitting, onto a plurality of wound rolls when the part webs are present separately from one another at the winding position. If the slitting of the material web is now begun as soon as the auxiliary device has passed through, it is possible to keep the “uncut” region very short.
  • the auxiliary device preferably draws the material web further after reaching the winding position until the longitudinal cut reaches the winding position. As a result, the individual wound rolls no longer stick together.
  • the material web it is preferred for the material web to be wound onto the auxiliary device in the region of the winding position until the longitudinal cut reaches the winding position. It is therefore no longer necessary to displace the auxiliary device further after reaching the winding position in order to convey the longitudinal cut(s) as far as the winding position. It is simply possible to rotate the auxiliary device or a part thereof in order to wind up the material web.
  • the material web is held firmly in the region 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 severed 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 to pick up the next material web start.
  • the auxiliary device is moved in a circuit from a pick-up position to the winding position and back.
  • the present invention includes an auxiliary device that can be moved from the unwind station as far as the winding station, into the region of the winding position.
  • a slitter having a cutting state, in which it produces at least one longitudinal cut in the material web passing through, and a passage state, in which the auxiliary device can be moved through the slitter.
  • the slitter has two rows of knives arranged on both sides of the material web in order to subdivide the material web into a plurality of part webs, two knives always interacting in order to produce a longitudinal cut. Therefore, in the cutting state, the knives have virtually no spacing or even overlap slightly. Then, if the auxiliary device is led through the slitter, the auxiliary device needs some space. For this purpose, the knives are moved apart accordingly. This is then the passage state. As a result of changing between the two states, it is possible to lead the material web through the entire rewinder at its full width, specifically through the slitter as well.
  • the slitter it is preferable for the slitter to have two crossmembers, of which at least one can be displaced relative to the other.
  • the displacement of at least one crossmember is generally simpler to implement than a correspondingly large displacement of the knives on this crossmember.
  • the auxiliary device is preferably guided on two movement paths which are arranged transversely with respect to the direction of movement of the material web and at a predetermined distance from each other.
  • the movement paths can be formed by rails or guides.
  • the fact that the auxiliary device is supported on two sides means that it is guided very stably.
  • the movement paths are arranged laterally outside the material web. These movement paths then do not disrupt the remaining constituent parts of the rewinder during operation. In particular, it is not necessary to take any measures in the region of the slitter in order to be able to close the slitter in spite of the presence of the movement paths.
  • the movement paths are located laterally outside the slitter.
  • the movement paths of the auxiliary device are preferably led in a circuit. Therefore, the auxiliary device can be led from the unwind station to the winding station on a first section of the movement paths and led back from the winding station to the unwind station in a second section. Leading the auxiliary device back therefore does not disrupt the operation of the rewinder.
  • the movement paths can be designed for a bidirectional movement.
  • the auxiliary device if necessary, can be led back from the winding station to the unwind station on the same section of the movement paths on which it has taken the opposite route during threading.
  • this has the disadvantage that the slitter can start its work somewhat later, since it has to remain open until the auxiliary device has been moved back.
  • it is possible to accept this disadvantage when space is restricted.
  • a transport device is preferably guided along at least one movement path. It is therefore not necessary for the auxiliary device itself to have a drive which moves with the auxiliary device. Instead, a stationary drive can be provided which then acts on the transport device.
  • the transport device can be formed, for example, as a chain, belt or cable and draw the auxiliary device along the movement paths.
  • a crosscutter which acts on the material web between the auxiliary device and the winding position is arranged in the region of the winding position.
  • the material web can therefore be severed between the winding position and the auxiliary device. This simplifies the threading of the material web. It is not necessary to release the material web from the auxiliary device first. Accordingly, it is not absolutely necessary to take care that the start of the material web is not damaged when it is gripped by the auxiliary device. A small section of the material web can be accepted as a loss, as long as it is the section which is needed by the auxiliary device to hold the material web.
  • the unwind station has a preparation position, underneath which a pulper opening is arranged, it being possible for the auxiliary device to be moved through a region between the preparation position and the pulper opening.
  • the unwind station generally has an unwinding position in which the parent reel is located as it is unwound.
  • at least one further space, namely a preparation position is provided in the unwind station.
  • a new parent reel is prepared, that is to say outer layers, which may possibly be damaged, are unwound and the straightest possible leading edge of the material web is produced, which runs at an angle of about 90° with respect to the direction of movement of the material web. This operation is also designated “squaring”.
  • a crosscutter is preferably arranged in the region. This facilitates the production of a clean material web start.
  • the crosscutter comes into action and severs the material web underneath the auxiliary device. The severed part falls into the pulper. The auxiliary device then holds the start of the material web firmly.
  • the crosscutter preferably has a dividing region which can be displaced in the direction of movement of the material web.
  • the parent or jumbo reels do not always have the same diameter. If the parent reel is always stopped in the same preparation position, then the start of the material web also hangs downward at different positions in the direction of movement. This is generally no problem for the auxiliary device, since it can be displaced in the direction of movement in any case and can therefore accommodate the small positional differences. If the slitter can likewise be displaced, then it is likewise possible to cope with these positional differences.
  • the auxiliary device preferably has suction openings and/or clamping means. Those are used to hold the start of the material web firmly. Suction openings hold the material web firmly with vacuum. Of course, in this case, it is necessary to ensure that air can be extracted from the auxiliary device or in any case from the suction openings. In the case of clamping means, it is merely necessary to ensure that these clamping means can grip the start of the material web and hold it firmly. Both holding devices can be controlled remotely, i.e. they can be operated from outside.
  • an activation device acting on the auxiliary device is arranged in the region of the unwind station. It is then possible to activate the auxiliary device at the instant at which it is to grip the material web. If the auxiliary device holds the material web firmly with the aid of suction openings, for example, then a vacuum can be produced in the auxiliary device with the aid of the activation device. If the material web is held firmly with the aid of clamping means, then the activation device can actuate the clamping means. As a rule, it is sufficient here if the activation device acts on the auxiliary device only at the start of the firm holding action.
  • the activation device is preferably constructed as a rotational drive which can be brought into an operative connection with the auxiliary device.
  • the rotational drive therefore rotates the auxiliary device, so that the auxiliary device winds up the start of the material web.
  • the material web holds firmly on the auxiliary device, as long as there is a certain tension. It is then possible, for example, to switch off the vacuum on the suction openings or to reduce the force of the clamping means.
  • the operative connection between the rotational drive and the auxiliary device can be produced via a clutch that can be engaged, so that the rotational drive does not also have to participate in the entire movement of the auxiliary device.
  • a rotational drive that can be brought into an operative connection with the auxiliary device is preferably arranged in the region of the winding position.
  • This rotational drive can also be coupled to the auxiliary device, for example by means of a clutch, after the winding position has been reached.
  • the rotational drive permits the auxiliary device to be rotated further and to wind up a region of the material web which has not been cut by the slitter. This makes it possible to draw the material web into the winding position, without further displacement of the auxiliary device, to such an extent that only already cut part webs are present at the winding position and these can be wound up to form separate wound rolls.
  • a splice station is preferably arranged between the unwind station and the slitter.
  • a splice station of this type can, for example, produce what is known as a “butt splice”, as described in DE 199 23 097 A1.
  • the splice station makes it possible to dispense with renewed insertion or threading of the material web into the rewinder when parent reels are changed. The start of a new parent reel is simply joined to the end of a virtually unwound parent reel.
  • the auxiliary device can preferably be moved in a space below a floor level on which the unwind station and the winding station are arranged.
  • the movement of the auxiliary device takes place in the “basement”, while the unwind station and the winding station are arranged on the “ground floor”. This arrangement increases safety. The risk that operators who remain in the region of the unwind station and the winding station will come into contact with the auxiliary device and be injured in the process is comparatively low.

This material web 9 is cut into a plurality of part webs in the slitter 4 and wound up in the winding station 3 to form a plurality of wound rolls 10 , of which only one can be seen in FIG. 1 , since these wound rolls 10 are located one behind another in a direction at right angles to the plane of the drawing.

  • For the purpose of preparation as a rule some layers of the material web are unwound and disposed of. This procedure is also designated “squaring”.
  • a pulper opening 19 is provided, which is arranged underneath the preparation position 14 , specifically in such a way that the material web 9 hanging downward under the action of the force of gravity encounters the pulper opening 19 . Since the parent reel 16 does not always have the same radius, the position of the material web 9 hanging down is displaced slightly. However, the pulper opening 19 is so large that it can intercept the material web falling down. If appropriate, a hopper 20 can also additionally be provided.
  • the rewinder 1 has an auxiliary device 21 , which is illustrated in different positions in FIG. 1 .
  • the auxiliary device 21 is provided with small letters (a, b, c) in different positions.
  • the auxiliary device 21 is led along a movement path 22 which is illustrated as a dash-dotted line.

  • a chain, a belt or a cable can also be led along the movement path 22 , these devices being driven by a common drive in a manner not specifically illustrated, so that the auxiliary device 21 can be led from the unwind station 2 to the winding station 3 in an orientation at right angles to the direction of movement of the material web 9 .
  • the auxiliary device 21 is now moved up from the left (based on the illustration of FIG. 1 ) to the material web 9 hanging vertically downward under the action of the force of gravity and is fixed to the material web.
  • the auxiliary device 21 can have suction openings in a manner not specifically illustrated. If a vacuum is produced at the suction openings, the auxiliary device 21 then holds the material web 9 firmly. Instead of the suction openings, clamping means which hold the material web 9 firmly can also be provided.
  • the auxiliary device 21 it is also possible for the auxiliary device 21 to be rotated about an axis (at right angles to the plane of the drawing), so that it winds up the material web 9 hanging down with a few revolutions. As long as sufficient tension is maintained in the material web 9 , the material web 9 holds firmly on the auxiliary device 21 .
  • the auxiliary device 21 can be connected to a stationary rotational drive, not specifically illustrated.
  • a crosscutter 23 can be actuated, which severs a superfluous section 24 of the material web 9 . This section 24 then likewise falls into the pulper opening 19 .
  • the crosscutter 23 can be displaced in the direction of a double arrow 25 in order to accommodate differences in the radius of the parent reel 16 which are reflected in different positions of the material web 9 hanging down. A change of this type in the position of the material web 9 is not critical for the auxiliary device 21 , since it can be moved along the movement path 22 in any case.
  • the auxiliary device 21 is then displaced along the movement path 22 to the winding station 3 and in the process leads the material web 9 around a plurality of deflection rollers 26 as far as the winding station 3 .
  • the movement path 22 maintains a sufficient distance from the deflection rollers 26 - 29 so that the material web 9 which is drawn behind the auxiliary device 21 wraps around the defection rollers 26 in such a way as is subsequently necessary during operation.

  • the slitter 4 therefore has a cutting state, in which the material web 9 can be cut into a plurality of part webs, and a passage state, in which upper knife 31 and lower knife 33 are at a distance from each other which is so large that the auxiliary device 21 can be moved through between the upper knife 31 and the lower knife 33 without difficulty.
  • the slitter 4 is closed again, so that the longitudinal cuts begin at a relatively short distance from the auxiliary device 21 .
