Definitions

  • the invention relates to a winding device for winding up partial webs of a web-shaped material according to the preamble of patent claim 1 and a method for winding up partial webs of a web-shaped material according to the preamble of patent claim 14.
  • foils are produced as continuous material and wound up in winding devices on winding tubes (cardboard tubes, plastic tubes, metal tubes, ).
  • winding tubes cardboard tubes, plastic tubes, metal tubes, .
  • a winding defect is e.g. B. the edge structure.
  • the outer edges of the roll fold over during the winding, as a result of which a clear increase in the diameter of the film roll at the edges of the roll can be seen.
  • the bad cut creates a thick spot on the edge of the film.
  • the continuous stacking of this film edge creates a significant increase in diameter in the edge areas of the film roll, that is, an edge build-up.
  • an edge build-up means that the finished film roll can no longer be unwound. It tears constantly during the unwinding process, which is the case, for example, with automatic packaging of goods makes these film rolls impossible. The reason for this is that the edge areas of the film are stressed much more, so tearing is very likely.
  • WO2014 / 076089 A1 discloses a winding device according to the preamble of claim 1 and a method according to the preamble of claim 14.
  • JP 2009 107792 A and JP H05 51154 A show devices for winding film rolls, wherein two rolls are provided, which act on the edges of the film roll. Also the EP 0 421 232 A1 discloses such a device.
  • the object of the present invention is therefore to propose a winding device and a method in which or in which partial webs of a web-like material are wound, with which such an edge structure can be reduced or even avoided entirely.
  • At least one roller is provided, the surface of which is on the edges of the partial webs of the web-shaped part located on two adjacent windings (103) Material can be adjusted with a positioning force.
  • edge means that the roll does not extend over the entire width of the roll, but at most up to a distance of 5 cm from the respective end face of the roll. However, it is not necessary that the entire surface of the roll be against the reel. Rather, part of the surface of the roll cannot be in contact with the roll.
  • edges of the web-like material which have already been placed on the winding by means of the contact roller, to be pressed on.
  • the following effect now avoids the build-up of edges.
  • a certain amount of air is usually wrapped between the layers of the web-like material.
  • the amount of air also has an influence on the diameter of the entire roll, not just the thickness of the sheet material.
  • the roll at the edges of the reel now displaces the air, which is now either released to the outside or pressed towards the center of the reel. Due to the now reduced amount of air in the edge area, the winding defects described above can be compensated for, so that the edge build-up is reduced.
  • a film wound according to the invention tends, for example no longer to tear, so that further processing can take place more reliably.
  • the at least one roller can be displaced parallel to the contact roller.
  • the position of the roll can thus be adapted to the width of the roll, so that the invention can also be used for rolls of different widths. It can further be provided that a variable number of roles can be used. It is thus possible to use the invention even if a web-shaped material is divided into several sub-webs by longitudinal cutting before being wound up, these sub-webs then being able to be wound up on separate tubes to form independent coils. However, these sleeves are often on the same winding shaft. In this case, it is even possible for a roll to rest against the edges of two adjacent coils.
  • this enables the amount of rolls required to be reduced and, on the other hand, the distance between the windings can be kept small without having to take into account the minimum distance between two rolls.
  • a single wrap is referred to as a "benefit".
  • the at least one roller is rotatably mounted in a bearing device which can be positioned at different points on a crossmember, the crossmember in particular extending parallel to the contact roller.
  • the bearing device can thus be arranged and also fastened at different locations on the crossmember in order to allow the above-mentioned adaptation to different widths of the roll or also to the number of uses.
  • the bearing device can be placed on the crossbar and screwed to it or clamped to it.
  • the traverse is designed as a rail on which the bearing device is slidably mounted, which simplifies handling. It is advantageous if the bearing device is designed as a slide. A shift is preferably done manually, but a motorized adjustment is also conceivable.
  • the roller is designed as an elongate roller which comprises at least one circumferential elevation, the surface of which can be adjusted at the edges of the partial webs of the web-shaped material located on adjacent windings.
  • a roller is thus provided here.
  • This roller carries an increase.
  • at least one ring is arranged on the roller, which acts on an edge of the roll.
  • the roller itself preferably does not come into contact with the sheet material. The use of a roller can bring a higher bending stiffness in comparison to the provision of a traverse, so that the contact force is constant over the width of the roller, in particular with a large number of uses.
  • the rollers or the elevations have a different diameter, which, for example, the larger the closer they are positioned relative to the center of the contact roller, since the greatest deflection increases there is expected.
  • these elevations can be displaced along the roller, so that adaptation to the blank or winding width is possible in a simple manner.
  • the at least one roller can be driven by a drive. It is therefore not necessary for the roll to be set in rotation by the winding. The latter in particular can damage the same, particularly in the case of sensitive materials.
  • This embodiment is advantageous in combination with an already described roller provided with elevations, since only a single drive is necessary here. In the case of separate rollers, several drives and / or gearbox connections are required in order to be able to apply a force for rotating the rollers.
  • the at least one roller can be driven in advance or in lag with a drive. That means, that the peripheral speed is greater or smaller than the peripheral speed of the winding. This can improve air displacement for certain materials.
  • roller or the crossbeam is arranged on two swivel arms which can be swiveled about a swivel axis running parallel to the contact roller.
  • An arrangement on swivel arms enables the roll to be simply positioned on a reel with a swivel bearing, which can be arranged somewhat away from the actual winding point. As a rule, the space is more favorable here.
  • the axis of rotation of the contact roller and the pivot axis run coaxially. This ensures that the roll can always come into contact with the roll, regardless of the diameter of the roll, and that the design effort is low.
  • a force supply device is provided with which the positioning force can be provided and which is supported in particular on a machine frame.
  • the power supply device can be supported on the machine elements which also carry the contact roller. This is particularly advantageous if the contact roller can be moved relative to the machine frame via the machine elements mentioned.
  • An adjusting force control can also be provided in a winding device according to the invention.
  • a positioning force measuring device is provided with which the actual positioning force can be measured.
  • this measured value provided by the contact force measuring device can then be compared with a target value.
  • the computing and control device emits control signals to the power supply device, on the basis of which the setting force can be changed.
  • the setpoint for the contact force can be changed depending on the material and / or the winding diameter.
  • the setting force can be increased or decreased as the winding diameter increases, preferably in a steady manner. The changes can be made linearly over the winding diameter.
  • a non-linear dependency is also conceivable.
  • the Figure 1 shows a winding device 100 according to the invention as it is preferably combined with a blown film line or a flat film line for the production of plastic film.
  • the web-shaped material 101 that is to say preferably a plastic web
  • the web-shaped material 101 is guided along a transport direction T onto a contact roller 102 which rotates in the direction R 1 .
  • the contact roller is placed against a roll 103 (or the roll 103 is placed against contact roll 102).
  • the web-shaped material 101 is guided by the contact roller 102 onto the winding 103 and pressed there.
  • the winding 103 is held firmly on the winding shaft 104, the winding shaft 104 rotating in the direction R 2 .
  • a roller 120 is rotatably mounted, the roller carrying elevations 121, which are preferably annular.
  • the roller 120 can be rotatably mounted on an axis, but is preferably arranged fixed on a shaft 122 which is rotatably mounted in the swivel arm 123.
  • the swivel arm 123 is in turn pivotally mounted coaxially to the axis of rotation of the contact roller.
  • the pivot bearing 124 of the pivot arm 123 can, however, be provided independently of the rotary bearing of the contact roller 102.
  • the contact roller can be rotated or rotated relative to the machine frame, not shown.
  • a force supply device K is provided, for example with a Pivot bearing on the machine frame and with a further pivot bearing on the swivel arm 123.
  • the power supply device can be realized by a piston cylinder unit operated by compressed air.
  • a hydraulic cylinder is also conceivable.
  • a power supply device operated by an electric motor is also fundamentally conceivable.
  • the Figure 2 now shows the view II - II from the Figure 1 , the same components being provided with the same reference numerals.
  • the web-shaped material consists of three individual webs 101, 101 'and 101 "and is therefore wound up on separate reels 103, 105 and 106. Nevertheless, these individual webs are fed in via the single contact roller 102.
  • the roller 120 carries a total of four bumps 121, 131, 141 and 151, the outer bumps 121 and 151 being positioned at one edge of the roll 103 and 106.
  • the central bumps 131 and 141 are, however, on the edges of each two coils are set in.
  • the elevation 131 is thus placed on the edges of the coils 103 and 105, whereas the elevation 141 is set on the edges of the coils 105 and 106.
  • a traverse 301 is provided, which is designed, for example, as a double-T beam in order to ensure the greatest possible rigidity.
  • the cross member 301 carries a rail 302 on which slides 303 are slidably mounted. This displaceability is indicated by the double arrows 304.
  • Support supports 305 are built onto each slide, in which a roller 306 is rotatably mounted.
  • the structure according to the Figures 3 and 4 replace the roller 120 with the elevations 121, 131, 141 and 151 and the shaft.
  • the cross member 301 can thus be attached directly to the swivel arms 123.
  • the rollers 306 then take over the function of the elevations 121, 131, 141 and 151, ie these rollers 306 can be adjusted against the edges of the windings 103, 105 and 106 in order to avoid the edge build-up.
  • the elevations 121, 131, 141 and 151 and the rollers 306 have a narrow width compared to their diameter.
  • the ratio of diameter to width can thus be at least 2: 1, but preferably 3: 1.
  • the transition from the peripheral surface to the end faces of the elevations or rollers can be rounded off in order to avoid markings on the web-like material which can arise in the case of an angular configuration. Such markings represent damage, at least in the case of plastic films.
