Definitions

  • the invention relates to a turret winding machine for winding up an essentially insulating web material with electrostatic fixing of the beginning of the web on a winding core.
  • Web materials are wound up into a roll, in particular directly after they have been produced, broken down into narrower webs, printed or further processed into bags, sacks or other packaging materials.
  • Spiral winding machines in particular are used for this. These have a rotatable winding core carrier on which several winding cores are rotatably mounted. By rotating the winding core carrier, the winding cores are shifted one after the other into a winding-on position for winding on a beginning of the web and into a winding-up position for further winding up of the web material.
  • the web material When the roll is fully wound in the winding position, the web material is severed by means of a cutting blade between the winding-on position and the winding-up position, and the following beginning of the web is wound onto the winding core in the winding-on position.
  • the fully wound roll is removed from the winding core support and replaced with an unwound winding core.
  • the winding core support is rotated until the winding core that has just been wound has reached the winding position and the still unwound winding core has reached the initial winding position, and the process begins again.
  • sleeves eg made of metal or cardboard
  • special adhesive tapes are used as winding cores, which fix the beginning of the web on the circumference of the sleeves. Gluing the beginning of the web limits the process speed, is expensive because of the adhesive tapes and is problematic for web materials for food.
  • adhesive-free initial winding refers to the fixing of the beginning of the web on a winding core during initial winding by means of electrostatic charging.
  • the web material When processing a web material that is essentially insulating, the web material can become highly electrostatically charged, in particular as a result of movement, deflection, friction, stretching and the use of electrostatic printing aids (ESA).
  • ESA electrostatic printing aids
  • the charges are stored in the material wound into a roll in a manner similar to that in a wound capacitor.
  • voltage flashovers can occur during further processing of the web material, which endangers workers. Therefore, devices for unloading the continuous web material are known.
  • the EP 3 222 421 A1 proposes a take-up device with a device for transferring electrical charges to the web material on the take-up roll and/or during deflection onto the take-up roll, which is connected to at least one electrical high-voltage source of positive or negative polarity, to compensate for unwanted charges. Also EP 0 183 135 A1 proposes a turret winder with a device for transferring electrical charges to fix the beginning of the web to the take-up roll.
  • the invention is based on the object of creating a turret winding machine for winding up an essentially insulating web material with electrostatic fixation of the beginning of the web with more favorable manufacturing and operating properties.
  • the turret winding machine with the same device for transferring electrical charges to the start of the web, charge is applied to fix it on the winding core in the initial winding position, and during further winding onto the same winding core, the charge required to compensate for charging during the production or processing of the web material is applied to the web material .
  • This is done by arranging the means of transmission electrical charges between the pressure roller, which can be displaced towards the winding core in the initial winding position, and the displacement path of the cutting blade when the web material is cut open.
  • both undesired charge of the web material before winding onto the winding core in the winding position can be compensated and after the web material has been severed, the following beginning of the web can be provided with a suitable charge for fixing on the winding core in the winding position.
  • the charging of the beginning of the web before fixing can be controlled in such a way that, despite the web material being charged during its production or further processing, adequate fixing on the winding core is achieved. Due to the fact that the device for transferring electrical charges takes over both the fixing of the beginning of the web and the compensation of electrical charges on the web material, components are saved and the space required is reduced. As a result, the outlay for production and operation can be reduced.
  • the high voltage electrical source supplies high electrical voltages of different polarity.
  • the electric control device controls which of the electric high voltages with different polarity are applied to the electric charge transfer device. If the device for transferring electrical charges is designed as a needle electrode, a high voltage of different polarity can be applied to different rows of needles or a high voltage of a specific polarity can be applied to one row of needles and ground can be applied to another row of needles. In the case of a needle electrode with only a single row of needles, a high voltage of a certain polarity can be applied to this row of needles and the housing to ground. For loading the beginning of the web for fixing to the winding core a high voltage of the same polarity can be applied to one or two rows of needles of a needle electrode.
  • the electrical high-voltage source supplies at least one adjustable high voltage to the device for transferring electrical charges onto the web material.
  • the high voltage By adjusting the high voltage, it is possible to optimize the charge supplied to the web material to compensate for charging of the web material. Furthermore, the charge supplied to the start of the web for fixing the web material to the winding core can be optimized.
  • the electrical control device is designed in such a way that it applies at least one electrical voltage to the device for transferring electrical charges with a level and/or polarity that causes the beginning of the web to be charged, which depends on the charging of the supplied web material.
  • the level and/or polarity of the charge for fixing the beginning of the web on the winding core can be set depending on the level and/or polarity of the charge to compensate for the charging of the web material, e.g. according to a table based on empirical values.
  • At least one field strength measuring device is arranged in such a way that it detects the web material fed to the turret winding machine, preferably when it is deflected onto the winding core or onto the winding core, with the field strength measuring device determining the charge that the web material has and being connected to the electrical control device , which is designed to apply a high voltage with a level and/or polarity to the device for transferring electrical charges that is determined by the charge of the web material measured by the field strength measuring device depends.
  • the electrical control device can determine the high voltage required to compensate for the charging and/or the high voltage required to charge the beginning of the web for fixing it on the winding core, taking into account the measured charging.
  • the electrical control device is designed in such a way that when the web material is being wound onto the winding core, it applies a high voltage to the device for transferring electrical charges with a level and/or polarity which causes minimal charging of the web material wound onto the winding core. This minimizes the risk of voltage flashovers.
  • the means for imparting electrical charges to the sheet material is a charging electrode arranged so that the sheet material passes through the effective range of the charging electrode. Since the charging electrode can act on the web material from a distance, it is possible to position and/or relocate the charging electrode so that it does not collide with moving parts. In addition, by arranging the charging electrode at a distance from the web material, changes in the course of the web material can be bridged to a limited extent, for example due to the increase in the roll diameter when the web material is wound onto the winding core.
  • the effective area of the charging electrode is defined as the area in which the field strength of the electric field generated by the charging electrode is at least 1% of the maximum field strength of this field, preferably at least 5%, preferably at least 10%, more preferably at least 20%. , preferably at least 50%.
  • the charging electrode when the beginning of the web is fixed on the winding core, the charging electrode is arranged in such a way that its effective area covers the outer circumference of the winding core arranged in the winding station. This is particularly advantageous for fixing the beginning of the web on the winding core.
  • the charging electrode is arranged on the same side of the web material as this pressure roller, next to the pressure roller that can be moved onto the winding core in the winding station.
  • the charging electrode is directed with its effective area through the web material onto the outer circumference of the winding core in the winding station.
  • the charging electrode is aligned with its effective area tangentially to the pressure roller that can be displaced on the winding core in the winding station. According to a further embodiment, the charging electrode is aligned radially to the winding core in the winding station when the web material is cut through.
  • the charging electrode is a bar-shaped charging electrode.
  • the charging electrode is a needle electrode.
  • the charging electrode is preferably designed like a charging electrode that is used for the " top-loading " of impression rollers in electrostatic printing aids (ESA).
  • ESA electrostatic printing aids
  • the charging electrode is a bar-shaped needle electrode designed as shown in FIG EP 1 640 160 B1 described, in particular as the needle electrode according to 1 to 10 or 11 to 14 of this specification.
  • the needle electrode has two parallel rows of needles.
  • the same voltage can be applied to both rows of needles to charge the beginning of the web.
  • the effective area is aligned axially in the direction of the needles.
  • the effective area can be characterized by the course of the field lines. These are lines of constant field strength.
  • the course of the field lines is elliptical, with the main axes of the ellipses being aligned in the direction of the needles and the secondary axes being perpendicular thereto.
  • the cutting device is designed in such a way that the displacement path of the cutting knife when cutting the web material runs between the winding core in the initial winding position and the axis of rotation of the winding core support.
  • the displacement path of the cutting blade preferably runs at a distance from the winding core in the winding-on position which is less than half the distance of this winding core from the axis of rotation of the winding core carrier.
  • the web material is separated at a short distance from the winding core in the winding-on position, so that the beginning of the following web wraps around the winding core in the winding-on position.
  • the wrapping and fixing is achieved by the electrical charging of the beginning of the web and, if necessary, the winding core.
  • the device for transferring electrical charges and the pressure roller arranged next to the winding position are fixed to the same supporting structure.

  • the support structure can be moved into and out of the area between the side parts by means of an infeed device. By shifting the support structure out of the area between the two side parts, it is possible to rotate the winding core carrier without colliding with the support structure and the components attached to it.
  • the electrical control device is connected to the infeed device and is designed in such a way that the support structure with the pressure roller mounted on it is moved out of the area between the two side parts after the beginning of the web has been wound and after the winding core on which the web material is wound has been rotated is shifted from the winding-up position to the winding-up position in the position adjacent to the unwound winding core rotated into the winding-up position.
  • the web material When the support structure is shifted out of the area between the two side parts, the web material continues to run over the pressure roller mounted thereon onto the winding core in the initial winding position. Here, the web material continues to be guided past the device for transferring electrical charges, which is attached to the support structure. This also compensates for charging of the web material when the supporting structure is shifted out of the area between the side parts. Even when the winding core carrier rotates the winding core from the initial winding position to the winding position, the web material is guided past the device for transferring electrical charges, so that the compensation of charges can be continued.
  • the supporting structure with the pressure roller is shifted between the side parts next to the still unwound winding core in the winding-on position.
