Definitions

  • the invention relates to an installation for handling or folding a material web, for example a continuous web, in particular a corrugated cardboard web. Furthermore, the invention is directed to a method for handling or folding a material web, in particular a corrugated cardboard web.
  • an installation for handling a material web is to be provided which is capable of folding or winding up the material web extremely neatly and quickly.
  • the folded or wound-up material web is to be particularly easy to handle or transport.
  • a corresponding method is also to be provided.
  • the core of the invention lies in the winding arrangement, which is capable of winding up a material web while forming folds, rebates or creases, preferably continuously. Due to the winding up or respective turning over of the material web, the latter has, for example, coherent portions or regions which run obliquely or at an angle to one another and enclose, for example, an internal angle of between 45° and 120° and are preferably flat. Alternatively, the wound-up material web has, for example, curved portions or regions. The folds created in the material web preferably run parallel to one another. They form parallel folds.
  • the wound-up material web has a contour that in principle corresponds to the outer contour of the material web winding-up region.
  • the guide arrangement ensures in particular a safe and exact guidance of the material web, in particular to the winding arrangement, and preferably a functionally safe and exact winding up of the material web. It comprises, for example, a guide table arrangement with at least one sliding surface for the material web and/or at least one guide roll for guiding the material web.
  • the conveying speed detection device is preferably designed as an optical conveying speed detection device. It preferably operates without contact. It is useful if the conveying speed detection device operates with electromagnetic radiation, such as light or laser radiation. It advantageously measures the conveying speed of the material web.
  • the conveying speed detection device comprises at least one conveying speed detection sensor or camera.
  • the conveying speed detection device for example, uses corresponding known process parameters of the installation, so that an independent measurement is not required.
  • the actuating device is preferably electrical, preferably electronic. It is at least temporarily in wired or wireless signal communication with the conveyor speed detection device. Conveying speed signals from the conveying speed detection device, which characterize or relate to the current conveying speed of the material web, can thus be received by the actuating device.
  • the rotary drive and the actuating device are preferably in wired or wireless signal communication. The actuating device is thus able to send or transmit corresponding actuating signals to the rotary drive.
  • the actuating device is designed, for example, as a control and/or regulating device.
  • the material web is multilayered, for example.
  • the material web is designed as a corrugated cardboard web. It is useful if the corrugated cardboard web is laminated on one or both sides. It then comprises at least two layers or plies thinly bonded to one another and arranged one above the other, such as at least one corrugated web and cover web.
  • the winding device formed as a polygon in cross-section at least in the material web winding-up region and preferably having between three and eight, preferably between three and six, corners in cross-section, is preferably equilateral and equiangular. It is preferably a regular, in particular convex, or equilateral polygon.
  • the winding device is preferably designed, at least in the material web winding-up region, as an, in particular straight, prism which has a corresponding polygon as its base surface.
  • Such a winding device leads to a particularly neat folding, turning over or winding up of the material web and has, in particular, straight running buckling regions or fold regions, in particular edges.
  • the corners of the polygon are sharp-edged, for example. Sharp buckling edges or fold lines can thus be produced in the material web. Alternatively, these are rounded, for example.
  • the buckling edges or fold lines formed in the material web are then not particularly pronounced and are rather weak.
  • the actuating device actuates the rotary drive differently in dependence on an existing number of layers of the material web on the winding device. It is useful then if the actuating device knows the existing number of layers of the material web on the winding device or a total length of the wound-up material web.
  • the rotary drive can preferably be driven in rotation at different angular speeds. In this way, for example, an increase in the lengths of the layers of the material web on the winding device can be compensated for as the number of layers on the winding device increases. This increase is due to the growing thickness of the material web wound up onto the winding device.
  • the target bending line distance detection device between the winding arrangement and the material web weakening apparatus for detecting distances between successive target bending lines in the material web, wherein the actuating device is at least temporarily in signal communication with the target bending line distance detecting device for detecting a respective distance between successive target bending lines in the material web and actuates the material web weakening apparatus in dependence on an existing number of layers of the material web on the winding device, is preferably of an optical type. It preferably operates without contact, for example with electromagnetic radiation such as light or laser radiation.
  • the target bending line distance detection device is capable of detecting the tartlet bending lines in the material web.
  • the actuating device and/or and the target bending line distance detection device is/are capable of detecting or calculating the distance of successive target bending lines in the material web.
  • the conveying speed detection device and the actuating device are combined, for example, into one unit. Alternatively, they are preferably designed or arranged separately from one another.
  • winding device together with the wound-up material web is replaceable allows for a simple transport of the unit comprising the winding device and material web, for example to a customer or to a remote or downstream working or processing arrangement.
  • a transportable solution for the material web is thus created. Process times can thus be shortened compared to the prior art.
  • FIG. 1 shows a schematic view of an installation according to the invention
  • FIGS. 5 to 10 show side views or cross-sections of alternative winding devices in their material web winding-up region or of winding cores of the installation illustrated in FIG. 1 .
  • FIG. 1 for folding or winding up an, in particular continuous, multilayer corrugated cardboard web 1 comprises a corrugated cardboard arrangement 2 for producing the corrugated cardboard web 1 .
  • a corrugated cardboard arrangement 2 is known, for example, from DE 103 12 600 A1, to which reference is hereby made.
  • the corrugated cardboard web 1 is conveyed or produced in a conveying direction 3 at a consistent or constant conveying speed v.
  • the embossing rollers 5 can be driven in rotation by means of an embossing roller drive device 8 , which is in driving connection with the embossing rollers 5 , for example via a coupling or a gearbox.
  • the folds have a distance d from one another in the conveying direction 3 or longitudinal direction of the corrugated cardboard web 1 and form target bending lines in the corrugated cardboard web 1 , along which the latter can be folded or creased in a particularly simple and controlled manner.
  • the corrugated cardboard web 1 is weakened at the folds or target bending lines and has a comparatively low bending strength there.
  • only exactly one embossing roller 5 has at least one embossing element 7 .
  • the other roller then forms a counter roller.
  • an optical detection device 10 Downstream from the crimping apparatus 4 in the conveying direction 3 is an optical detection device 10 , which is assigned to the corrugated cardboard web 1 .
  • the detection device 10 is capable of detecting the actual conveying speed v of the corrugated cardboard web 1 in the conveying direction 3 .
  • the detection device 10 is capable of detecting the actual respective distance d of the folds or target bending lines in the corrugated cardboard web 1 in the conveying direction 3 or the longitudinal extension of the corrugated cardboard web 1 .
  • the detection device 10 for example, has a conveying speed detection sensor and a fold or target bending line detection sensor.
  • the winding arrangement 11 comprises a support frame 12 which is supported relative to a floor.
  • the support frame 12 carries a receiving device which has at least one first support or bearing means.
  • the winding core 14 also has two opposing end faces 19 which centrally support the at least one second support means.
  • the winding arrangement 11 further comprises a rotary drive 25 , which is in driving connection with the winding device 13 and is capable of driving the latter in rotation in a direction of rotation 20 or its circumferential direction about its central horizontally extending central longitudinal axis 21 .
  • the actuating device 22 also has a receiving unit 26 which is at least temporarily in signal communication with the detection device 10 and is capable of receiving signals relating to the current actually prevailing conveying speed v of the corrugated cardboard web 1 and the distances d between successive folds.
  • This signal communication can be wireless or wired.
  • the conveying direction 3 of the corrugated cardboard web 1 and the direction of rotation 20 of the winding device 13 are substantially identical. It is convenient if the corrugated cardboard web 1 is under tension or strain during winding up.
  • the length of the respective layer of corrugated cardboard web 1 newly wound up onto the winding core 14 increases.
  • the straight regions of the corrugated cardboard web 1 extending adjacent to each side surface 16 of the winding core 14 correspondingly become longer per layer.
  • the length of the layers of the wound-up corrugated cardboard web 1 also depends on the thickness of the corrugated cardboard web 1 .
  • the crimping apparatus actuating unit 23 actuates the embossing elements 7 in such a way that the folds or target bending lines always come to lie adjacent to the edges 17 or corners 18 of the winding core 14 or to folds of the corrugated cardboard web 1 lying below them.
  • the folds in each layer lie above the folds of the layer arranged below. With each layer of corrugated cardboard web 1 wound up onto the winding core 14 , the distance d between successive folds is thus increased. In doing so, the distance d depends on the number of layers and the corrugated cardboard web 1 wound up with them, and increases.
  • the detection device 10 thereby detects the current distance d of successive folds and the current conveying speed v of the corrugated cardboard web 1 in the conveying direction 3 .
  • an information unit 27 is firmly connected to the winding core 14 . It is arranged at a support or bearing means of the winding device 13 and is designed as an RFID tag.
  • the installation can be operated without the crimping apparatus 4 .
  • the edges or corners of the winding core are then designed in such a way that they themselves form target bending lines in the corrugated cardboard web. They are sharp-edged.
  • FIG. 5 shows a winding core 14 which has the cross-section of an equilateral triangle or has the outer contour of an equilateral triangle in cross-section.
  • the winding-up region 15 is formed by flat surfaces 16 which are inclined to one another, are arranged consecutively in the circumferential direction and are separated from one another by three edges 17 which are running parallel to one another.
  • the edges 17 extend perpendicularly to the conveying direction 3 of the corrugated cardboard web 1 .
  • the winding core 14 has three corners 18 which are ends of the edges 17 and have an angle of 60° in each case.
  • the winding core 14 is supported as to be driven in rotation at its center of gravity or center. Otherwise, reference is made to the previous explanations with respect to the design of the angle arrangement 11 or with respect to the function of the installation.
  • FIGS. 6 to 9 show further winding cores 14 which can be used alternatively and which are designed in cross-section as an equilateral or regular pentagon ( FIG. 6 ), hexagon ( FIG. 7 ), heptagon ( FIG. 8 ) or octagon ( FIG. 9 ).
  • FIG. 6 shows further winding cores 14 which can be used alternatively and which are designed in cross-section as an equilateral or regular pentagon ( FIG. 6 ), hexagon ( FIG. 7 ), heptagon ( FIG. 8 ) or octagon ( FIG. 9 ).
