    专利说明:

    The invention relates to a former, softer essentially consists of a triangular sliding plate and attached to the funnel legs of the sliding plate guide elements. Furthermore, the invention relates to a longitudinal folding device, which essentially comprises, in addition to a former, a strip line for transporting the substrate to be folded, such as a material web or a sheet, and optionally an outlet-side conveyor device.
    Furthermore, the invention is directed to a method for longitudinal folding of a web or sheet-like substrate using the inventive Längsfalzvorrichtung.
    [0003] The prior art discloses longitudinal folding devices, i. Devices which fold a web or sheet from a foldable substrate in the direction of transport of the substrate, such as, for example, blade folders, plow folds or formers. Although Schwertfalzvorrichtungen are suitable for folding sheets or sheet stacks of a foldable substrate, but are complex and complex devices with a variety of moving components and are therefore relatively expensive. Folding funnels or plow folds, on the other hand, are static structures which only require comparatively few and less complex moving components in their periphery. However, it is not possible with the hitherto known from the prior art formers or Pflugfalzen under normal circumstances, to fold sheets or sheet pile.
    Although, for example, from DE 19 811 109 A1 a former with additional means of transport on the hopper plate known, yet it is not possible with all known from the prior art formers, reliable and especially at higher speeds by separating a web transverse to the transport direction arc formed in both dimensions perpendicular to the substrate thickness finite dimensions or even sheet stack of a plurality of superimposed sheets by means of a folder and thus reliably fold by means of a device of no or few moving parts.
    The invention is therefore an object of the invention to provide a solution with which either a single web or more superimposed sheets or a single folded or unfolded sheet or a plurality of superimposed sheets - regardless of whether they are already folded - by means a static Längsfalzvorrichtung reliably fold as well as at higher speeds in the transport direction of the web or sheet.
    In the inventive method, this object is achieved in that a triangular sliding plate and at least one ribbon cable, which tapers to the base edge of the sliding plate for transporting the at least one incoming sheet to be folded or the sheet to be folded, as well as from guide elements, which The two funnel legs are mounted at an angle to the sliding plate of about 100 ° to about 20 ° and wherein the edges between the vanes and the sliding plate preferably have a radiused or rounded transition, and wherein the guide elements at the opposite corner of the base edge of the sliding plate have an outlet opening to each other and wherein the incoming web or the incoming sheet on the side facing the guide elements of the sliding plate can be supplied, so that by running the outer edges of the sheet to be folded or the sheet to be folded on the guide elements, the web or the sheet Transportri is falzbar. The side facing the guide elements of the sliding plate is thus the web- or sheet-guiding side of the sliding plate in the novel folding former or in the inventive method.
    Such a longitudinal folding device has, on the one hand, the advantage that not only webs can be folded in the transport direction by means of a former, but also that sheets or stacks of superimposed sheets, so-called sheet stacks, which are guided by the inventive longitudinal folder, reliably be folded, which significantly increases the flexibility of corresponding production facilities.
    Furthermore, with the inventive Längsfalzvorrichtung a sheet or sheet pile - hereinafter these two terms are covered exclusively with the term bow - be folded with a device which has only a few moving parts and thus can be easily and inexpensively manufactured.
    Furthermore, in comparison to other known from the prior art Längsfalzvorrichtungen for folding sheets such as rotating folding drums with therein eccentrically mounted and also rotating folding blade and the associated folding rollers in the inventive Längsfalzvorrichtung the few moving parts still very simple and are performed little complex parts, which also reduces the production costs.
    In addition, it is also mentioned that such a simple mechanical construction of the inventive longitudinal folding device also requires only minimal control effort, which avoids high costs and is much easier to control on the other procedurally, since fewer control algorithms must be observed.
    Thus, a first embodiment of the invention consists of a triangular or substantially dreiecksförmigem sliding or sliding surface, wherein on the legs of the sliding plate in the same direction pointing guide elements are attached, which enclose an angle of preferably 90 ° to 30 ° with the sliding plate. The thus resulting edges between the sliding plate and the guide elements on the legs of the sliding plate have a rounded transition, which is designed for example as a radius. On the inlet side of the sliding plate, a first transport device is mounted, for example in the form of a ribbon cable, which conveys the substrate to be folded on the base edge of the sliding plate opposite the two legs. At the opposite corner of the base edge, the two guide elements do not collide, but end before, so that between these seen in the transport direction of the substrate to be folded outlet edges an exit opening for the substrate to be folded remains.
    The sheet to be folded or the sheet to be folded with the first transport device, which, for example, as a ribbon consisting of upper and lower belt with at least one conveyor belt pairing over the defined by the length of the base edge width of the sliding plate or the inventive Längsfalzvorrichtung transported the base edge of the sliding plate. In contrast to the known from the prior art folding funnels according to the invention, the sheet to be folded or the sheet to be folded does not run on the side facing away from the guide elements of the sliding plate and wraps around this, but according to the invention to be folded substrate on the facing the guide elements Surface of the sliding plate or the sliding surface on this. Due to the longitudinal movement of the substrate, the lateral edges or corners run on the inside of the guide elements or on the rounded edges between the guide elements and the sliding plate, so that they are seen by the inclination of the guide elements to the sliding plate as well as by the transport direction of the substrate existing angle between the baffles are more and more turned over until it is completely taken and emerges as a folded product from the outlet-side outlet opening between the two guide elements.
    In an advantageous embodiment of the invention, the inventive designed as a former longitudinal folding means on the outlet side of the sliding plate and thus immediately at the outlet edge of the guide elements comprises an additional conveyor, which either as a pair of rollers or as a discontinued ribbon cable or as a combination of Zugwalzenpaares and a ribbon cable can be executed. This ensures that the already taken in and folded leading edge of the sheet to be folded is detected by the conveyor and thus controlled out of the longitudinal folding device is pulled. Advantageously, the Längsfalzeinrichtung is based on the length of the sheet to be folded dimensioned such that the sheet to be folded is already detected by the outlet side conveyor, as long as it is still guided and transported by the inlet side transport device. This outlet-side conveyor is arranged at least approximately at right angles to the inlet-side transport device.
    In a further particularly advantageous embodiment of the invention is in at least one section over the length of the base edge of the sliding plate and thus at least one section over the width of the sliding plate a transport device, in particular a ribbon cable, with which the sheet to be folded or to folding sheet is fed to the sliding plate, carried out such that the transport device projects in the transport direction on the side facing the guide elements of the sliding plate over the base edge and covers the sliding plate as far as possible.
    With such an embodiment of the invention, the substrate to be folded can be performed as long as possible, so that the area can be minimized without guidance by a transport device in the event of the presence of an outlet-side conveyor, which is the folding accuracy and the maximum possible transport speed good ,
    In a particularly advantageous embodiment of the invention, the inlet-side transport device is designed as a ribbon cable with transversely to the transport direction seen a plurality of juxtaposed ribbon cables, each consisting of an upper and a lower band. Thus, an upper belt on the guide elements facing away from the surface of the sliding plate or the sliding surface are guided over this, while the lower band of the strip line is guided over the side facing away from the guide elements. Thus, when seen at least in the transport direction of the substrate sections at the areas in extension perpendicular to the transport direction, where a top and bottom band is performed, recesses are mounted in the sliding plate, between the top and the associated sub-band at least one terminal point can be generated so that the sheet to be folded or the sheet to be folded, which is guided in each case over the guide elements facing surface, ie the web or the sheet-guiding surface of the sliding plate or the sliding surface, are guided between the upper and lower belt.
    In a further advantageous embodiment of the invention, the sliding plate with the two attached to the legs of the sliding guide elements in a plane which is perpendicular to the sliding plate and is also aligned perpendicular to the base edge, separated, so that the composite of sliding plate with the two there attached guide elements are designed as two shell-like structures which are arranged in an advantageous manner, but not mandatory, seen in the transport direction side by side, that seen between these two shell-like structures perpendicular to the transport direction, a distance is present in the at least one first transport device , Preferably a ribbon line consisting of upper and lower band, as far as possible to the outlet edge for optimal guidance of the substrate to be folded in the region of serving as a sliding plate part of the shell-like structure extends and the sheet to be folded or to no longer fold over the one guide elements facing the sliding plate, but over the guide elements facing the sliding surface, which is thus composed of at least two parts, is guided. The guide elements facing sliding surface is thus the web or sheet-guiding sliding surface.
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Various embodiments of the invention will be described, without being limited thereto, with reference to the drawings.

    1 shows a first embodiment of the inventive longitudinal folding device 1. This comprises a former 7 from a nearly triangular or triangular sliding plate 10, which has a base edge 11 on the inlet side 4, to which the two funnel legs 12 are adjacent. With regard to the triangular shape, it should be noted that the sliding plate 10 can not represent an exact triangle, since in various embodiments, the corner 11 opposite corner due to a shortening of the sliding plate 10 can be omitted, yet describes a triangle, the basic design of the sliding plate 10 most vividly.
    Preferably, the sliding plate 10 is designed as an isosceles triangle to ensure a symmetrical folding. However, the sliding plate can also be designed, for example, with rounded or curved funnel limbs 12 or even a rounded or, for example, rounded base edge 11, or the funnel limbs 12 can also be designed, for example, as angled lines. With such embodiments, in which in particular the funnel legs 12 are not designed as a straight edge, the folding and / or discontinuation behavior can be changed. Because of these possible, deviating from a classical triangle shapes of the sliding plate 10, these possible designs are covered by the concept of a triangular shape.
    If it is assumed that the longitudinally folded web 2 or the longitudinally folded sheet 2, the longitudinal folding device 1 according to the invention lying on a vertical plane should emerge from the longitudinal folding device 1, then the required angles result due to the funnel laws, it being noted hereby that these are all correlated to each other, so that usually has to change when changing an angle and another angle. The serving as the leading edge base edge 11 is usually on a horizontal plane, thus resulting in an angle β of the sliding plate 10, which is the angle between a vertical plane and the triangular surface of the sliding plate 10, from about 10 ° to about 40th °. For an embodiment in which the sliding plate 10 has the shape of an isosceles triangle, so this has a known from the field of the outer funnel funnel angle a, which is the base edge 11 opposite, from about 40 ° to about 90 °. The dimensions of the sliding plate 11, in particular the required effective width of the base edge 11, results from the size and, in particular, from the maximum width of the substrates to be folded, such as web 2 or sheet 2.
    With regard to the substrates to be folded is noted at this point that the inventive Längsfalzvorrichtung 1 and the inventive Forming hopper 7 can fold both in width but in the length actually endless webs 2, which is a single web 2 or a Can act a plurality of superimposed webs 2 of the same or different width. Also, with the inventive longitudinal folding device 1 or the inventive former 7 both in the width and in the length limited sheet 2 or more superimposed sheets 2, so-called sheet stack 2 are folded, regardless of whether this at least one web 2 or a single Sheet 2 or the sheet stack 2 is still unfolded or already has a fold in or transverse to the transport direction of the sheet 2 or sheet 2 to be folded. For this reason, the term of the substrate 2 or of the substrate 2 to be folded 2 is frequently used hereinafter as well. For sheet stacks 2, it is advantageous, but not a mandatory feature that the sheets 2 of the sheet stack 2 have a certain cohesion to each other, for example, by electrostatic blocking, a Hilfsverleimung or, for example, a linking.
    At each funnel leg 12 of the sliding plate 10 of the former 7 one or more juxtaposed guide elements 14 is mounted in each case. Each of the two guide elements 14 begin at the base edge 11, seen in the transport direction 3 in width perpendicular to the sliding plate 10 and form the outlet end, which is usually on a horizontal plane, assuming that the folded products 2 from to be outputted to the former 7 in a vertical plane.
    Between the sliding plate 10 and the two guide elements 14 there is a bending angle y, which is in a range of about 100 ° to 20 °, preferably in a range of 90 ° to 30 °. Usually, the bending angle over the entire length of the funnel legs 12 is constant, but it is also possible that the bending angle y changes over the length of the funnel legs 12.
    Depending on the geometry of the longitudinal folding device 1 and / or the substrate to be folded 2, it may be advantageous that the bending angle represents an obtuse angle, but usually the bending angle is either a right angle or an acute angle.
    In order to ensure a good transition, in particular the edges of the substrate to be folded, the edge between a guide element 14 and the sliding plate 10 is rounded, such as by a radius or a radius-like transition executed. The radius r is advantageously in a range between about 20 to 80 mm. Also, this radius r can be made constant or variable over the length of the funnel leg 12. In the case of a variable radius over the length of the funnel leg 12, it is usually larger in the area of the base edge 11 than on the outlet side of the longitudinal folding device according to the invention.
    As materials for the sliding plate 10 and the guide elements 14 can be used in addition to metallic materials such as preferably steel non-metallic materials such as ceramics, plastics or fiber composites to minimize possible wear, these components can in particular on to be folded with the Substrate in contact surfaces with low-wear materials such as ceramic coatings, hard chrome, etc. are coated. However, it is also possible to apply the surfaces coming into contact with the substrate 2 to be folded, if appropriate, in addition to a wear-inhibiting coating with an air cushion in order to minimize possible wear by the air cushion.
    At the outlet end of the sliding plate 10, the ends of the guide elements 14 do not meet together, but form an outlet opening 15 through which the folded substrate 2 can escape from the inventive longitudinal folding device 1. This outlet opening 15 usually has a width of about 20 mm to 100 mm, which depends on the one hand on the geometry of the longitudinal folding device 1 as well as on the substrate to be folded.
    On the inlet side 4, the inventive Längsfalzeinrichtung 1 has a designed as a ribbon 20 on the inlet side transport device for the substrate to be folded. In principle, this inlet-side transport device can also consist of one or more draw rollers or transport rollers. However, the use of a ribbon cable 20 offers the advantages that it can be conveyed very easily and accurately even to be folded sheet 2 or sheet stack 2. This inlet-side ribbon 20 may be performed in the simplest case as only one band, which is in contact with only one side of the incoming substrate 2, if necessary, can set on the opposite side of the tape a tension roller.
    Preferably, the inlet-side ribbon cable consists of an upper belt 20-1 and a lower belt 20-2, between which clamped to be folded substrate 2 and is transported to or in the Längsfalzeinrichtung 1. Usually, but not exclusively, come across the width of the incoming substrate 2 and thus over the width of the base edge 11 of the sliding plate 10 a plurality of adjacent top bands 20-1 and sub-bands 20-2 are used. But it is also possible that the ribbon 20 only consists of a band across the width of the base edge 11.
    On the outlet side 5 of the longitudinal folding device 1 is usually also a conveyor 25 is mounted. However, this can also be omitted if, for example, an endless web 2 is folded, which is conveyed by one of the Längsfalzeinrichtung 1 downstream component again, so that builds up a corresponding web tension between the outlet side 5 and the inlet side 4 of the longitudinal folding device 1.
    Preferably, this outlet-side conveyor device 25 is constructed as a spout strip line 27, which again clamps the longitudinally folded substrate 2 between an upper belt 27-1 and a lower belt 27-2, so that a corresponding train is constructed. Such an embodiment is shown in Fig. 1. Usually located over the width of the folded substrate 2 a plurality of adjacent bands; but there is also a possibility that over the width of the folded substrate 2 only a possibly wider band is arranged.
    Another advantageous embodiment of the invention is a conveying device which is formed from at least one pair of rollers 26 are employed in the two rollers to each other and at least one roller is driven, so that by adjusting the two rollers to each other a web tension can be established ,
    In a particularly advantageous embodiment of the invention, the conveyor 25 consists of a combination of a pair of rollers 26, which acts as Zugwalzenpaar, and a run-out stripline 27 running on it, so that the folded substrate 2 of the pair of rollers 26 optimally pulled and from the outlet stripline 27, which preferably consists of a top band 27-1 and a bottom band 27-2, stably guided and further transported.
    Advantageously, but not necessarily, the inventive Längsfalzeinrichtung 1 is sized and designed so that the length of the sliding plate 10 seen in the transport direction 3 is shorter than the length of the sheet to be folded 2. However, for example, in format variable printing, cutting or folding systems, the length of the sheets to be folded 2 is highly variable, even very short sheets 2 must be able to be performed optimally.
    For this purpose, an advantageous embodiment of the invention is shown in Fig. 2, at softer at least one inlet-side ribbon 20 on the guide elements 14 facing side of the sliding plate 10 and thus on the web or sheet-guiding side of the sliding plate 10 in the transport direction 3 seen above serving as the leading edge base edge 11 addition, so that the substrate to be folded 2 at least in a section over the width of the sliding plate 10 and thus at least a partial section over the width of the substrate to be folded 2 much longer between the guide elements 14 facing band of the ribbon line 20 is performed. Thus, also sheets 2 can be folded, which seen in the transport direction 3 have a smaller length than the length of the sliding plate 10.
    In this case, the substrate 2 is either, as shown in Fig. 2, between the sliding plate 10 and a band, which is then usually referred to as the upper band 20-1, is guided, wherein in such a configuration over the base edge 11 of Sliding plate 10 beyond band line 20 is designed as a sliding over the sliding plate 10 upper belt 20-1.
    In a particularly advantageous embodiment of the invention, as shown in Fig. 3, the entire inlet-side ribbon cable 20 protrudes from at least one top band 20-1 and at least one sub-band 20-2 consisting, in at least one section over the width of the sliding plate 10, seen in the transport direction 3 over the base edge 11 of the sliding plate 10 addition. In order to be able to guide the substrate 2 to be folded between the upper belt 20-1 and the lower belt 20-2 in such a configuration of the ribbon cable 20, the sliding plate 10 has to be at the partial sections at which over the width of the base edge 11 strip lines 20 consisting of upper belt 20-1 and lower band 20-2 are mounted, seen in the transport direction 3 at least partially cutouts 13 have. At these recesses 13 are mounted either for the upper belt 20-1 and / or for the lower belt 20-2 tape rolls to ensure at these points a clamping point between the upper belt 20-1 and lower belt 20-2, clamped by which the substrate 2 to be folded and thus guided or transported.
    However, it is also possible in the embodiment shown in Fig. 3, in the at least one region, on which an over the base edge 11 beyond band-line 20 is mounted, the sliding plate 10 over the length of the ribbon 20 completely auszusparen, so that in this at least one section, the substrate 2 to be folded can be guided over the entire length of the ribbon cable 20. Here, over the width of the sliding plate 10 arranged strip lines 20 may extend beyond the width of the base edge to different degrees to avoid a collision of the strip lines 20 with the guide elements 14.
    As seen in the transport direction 3 far beyond the base edge 11 extending tape line 20 thus very far with at least one slot or step-like recess 13, the sliding plate 10 must be recessed, consisting of the sliding plate 10 and the two guide elements 14 static Area of the longitudinal folding device 1 as two symmetrical to a median plane 6 executed angular shells 16 which are arranged at a corresponding distance, which is perpendicular to the transport direction 3, to each other. The guide elements facing surface of the sliding plate 10 is thus the web or sheet-guiding surface of the sliding plate 10th
    Such a particularly advantageous embodiment of the invention is shown in Fig. 4. In this variant, the former 7 is designed to be split, the sliding surface 17 resulting from several parts, together with the guide element 14 formed thereon, forms an angular or cup-shaped element, which is referred to below as a shell 16. Also in this embodiment, the guide elements 14 facing side of the sliding surface 17 thus the web or. arc-guiding side of the sliding surface 17th
    Two symmetrically spaced shells 16 replace the resulting from a sliding plate 10 and two guide elements 14 former 7 This illustrated in Fig. 4 invention has the advantage that, for example, the width of the outlet opening 15 can be made variable , so that these and thus the geometry of the purely static part of the Längsfalzeinrichtung 1 can be made variable or adjustable. Furthermore, such a configuration has the further advantage that the inlet-side ribbon cable 20 can be carried out for a very long distance to the outlet opening 15 and that when designing the ribbon cable 20 from upper band 20-1 and lower band 20-2 the substrate 2 to be folded very far into the sliding surface 17 and thus already clamped even when initiating the folding process by the ribbon cable and thus guided and controlled promoted.
