Definitions
- the invention relates to a folding plate plant and a method for folding flat goods.
- Flap tappets are known, for example, from DE 198 24 298 A1, from DE 202 00 716 U1 and from DE 20 2008 003 683 U1. However, these are not suitable for mechanical operations, especially when printed matter to be folded with cards.
- FR 2 739 593 A1 DE 20 2007 004 207 U 1, DE 10 2005 009 328 B4 and FR 2 795 058 A1 also disclose folding machines and corresponding folding methods in which the flat material is first of all First, a folding guide
- Flappfalzwerke fundamentally differ from Schwertfalzwerken in that in the latter first the fold break occurs and then the folding takes place, while folding folding works first a folding is made in order then to perform the fold break.
- the independent movement of the folding mechanism and the folding ram enables the flat material to be folded to be folded into a fold before the fold is broken. This allows with a suitable design of the folding plant especially a very fast process management.
- a folding plate for folding flat material by at least one folding die and at least one further folding tool and by at least one punch drive for performing a folding acting counter punch movement of the folding die and / or the further folding tool with a component perpendicular to the folding axis distinguished.
- the folding axis runs along the seam break through the folded flat material.
- the respective folding axis is not known before folding or a fold for the respective slab.
- the assemblies of each flaps are tuned to each other such that within the process accuracy the folding axis is approximately at the same location after each folding - in the area in the hemming and other folding tool on each other - so that the corresponding folding axis taking into account the location of the folding tools is known.
- More complex is the definition of the folding axis, which corresponds to folded flat material of the folding axis.
- the folding axis is referred to as the line which runs through the flat material and is furthest away from the opening of the respective fold. It should be emphasized that a folding axis can be defined accordingly even in the case of an only arched fold in which no kink is yet to be recognized.
- the folding punch and / or the further folding tool have a flat active surface.
- any inaccuracies in the fold provided by the folding mechanism and thus caused variations in the folding axis can be compensated easily when the folding punch and the other folding tool act on the flat material in the folding axis and bring about the fold breakage in this way.
- the folding punch and / or the further folding unit can have a yielding active surface.
- the resilient active surface can enclose the flat material at the fold and penetrate as far as the opposite active surface, so that the fold fracture can be made relatively intensive.
- a resilient active surface can be provided for example by an elastic material, such as plastic.
- the folding plate plant comprises a punch guide which predetermines the punch movement and which is arranged rigidly on a housing of the folding plate plant.
- the punch guide in which the punch guide is moved with the folding mechanism, the punch movement can be easily and reliably repeated by a rigidly provided in a housing punch guide. This then also allows a high speed of the folding plant.
- a folding hammer can be used in particular as a folding punch.
- the further folding tool can also be a folding hammer, so that two counter-rotating movements are provided. It is the same conceivable that the further folding tool is a folding anvil, on which the folding hammer acts to break the fold.
- the folding mechanism preferably places the fold of the respective flat product laid to form a fold in the fold-breaking effective region of the folding punch and / or of the further folding tool.
- the folding mechanism can have a folding flap pivoting about the folding-breaking effective region of the folding punch and / or of the further folding tool. Both alternatives thus require a fixed Falz mecanicden effective range, in which the folding mechanism or the jaw folds the folds, so that the folding tools can selectively perform the fold break without the falz mecanicde effective range must be relocated. This requires a relatively reliable procedure.
- the pivot axis of the pivoting folding flap is preferably parallel to the longitudinal direction of the effective range and / or parallel to the folding or folding axis. This requires a particularly reliable process management.
- the folding mechanism can have a pivot axis which intersects or touches the surroundings of the folding-breaking effective region. In this way, a folding axis can be reliably brought into the falz mecanicden effective range.
- the "environment of the falz mecanicden effective range” defined by a cylindrical space whose center axis in the middle of the colliding active surfaces of the two folding tools, parallel to the folding axis and its radius of the sum of the two longitudinal extents of these active surfaces perpendicular to the central axis equivalent.
- a folding guide can be introduced into and removed from the environment of the falz mecanicden effective range, preferably in the falz mecanicden effective area itself.
- the folding guide is used here to ensure a targeted fold before breaking the fold.
- the folding guide is deducted from the folding axis immediately before the fold break when the fold was placed correctly so that it is a little removed from the fold and the fold break is not hindered.
- the folding guide is part of an assembly which is surrounded by the fold formed by the folding mechanism and the folding axis is closest. For example, this may be the leading edge of a folding blade or folding knife or the leading edge of a leaflet.
- a folding plate plant for folding flat material with at least one folding guide can be distinguished by the fact that the folding guide is movable at least in a movement region parallel to the folding opening direction and / or parallel to the folding axis of a fold or a fold of the flat product.
- a folding plate plant for folding flat material with at least one folding guide can be characterized in that the folding guide is rigidly guided at least in a movement region perpendicular to the folding opening direction and perpendicular to the folding axis of a fold or a fold of the flat product.
- a method for folding flat material in which first the flat material is prefolded by means of a Falzkjappe to a folding guide to a fold and then the folding break is executed, characterized in that the folding guide before, during or after performing the fold break is completely removed from the fold.
- this procedure allows then to promote the slab in the direction of the fold guide on.
- the folding guide can be deducted at least a little from the folding axis before the fold break, as also briefly indicated above.
- the folding guide is removed from the fold at a speed which is greater than the speed with which the fold is moved with respect to the folding rupture-causing folding tools. This requires that any movement of the flat guts by the folding guide, which is removed from the fold, is not hindered.
- the latter is particularly advantageous if the folding guide is moved in the same direction with the folded or folded flat material, as can be understood immediately due to the sense of motion.
- a folding plate for folding flat material with at least one folding guide can be characterized in that the folding guide is formed in the longitudinal direction of the fold or parallel to the folding axis of the flat material shorter than folded or folded around the fold guide flat material. This means that less mass must be moved and shorter distances must be covered so that the folding guide can be moved very quickly.
- the folding guide can be designed to be divided in the longitudinal extension of the fold or parallel to the folding axis, which may also be advantageous for folding flat material with at least one fold guide independently of the other features of the present invention in a folding mill to ensure the folding guide.
- each part of the folding guide has its own pivot axis, whereby correspondingly high speeds can be ensured for the folding guide.
- the folding guide can be pivoted away from the fold, in particular in order to shift the folded flat material possibly also in the direction of the fold guide or to remove the fold guide a little from the folding axis before the fold break.
- the further folding tool which interact with the folding punch or the folding hammer, be arranged on a jaw of the folding plant. This is relatively space-saving, since for the further folding tool, in particular accordingly for the folding anvil, no separate assembly must be provided.
- the folding mechanism or the folding flap is in any case in contact with the folded flat material, so that a relatively accurate positioning of the flat product or the fold of the flat product with respect to the further folding tool can be ensured.
- the folding guide on a folding sheet which corresponds approximately in the prior art approximately the rear part of the folding blade - the process management in the present folding plant is completely different than in Schwertfalzwerken - arranged.
- a folding sheet provides a good investment for the to be folded or to be folded flat material, which is accordingly advantageous.
- the folding guide could for example be designed as a rod, rod or the like.
- Both the folding punch or the further folding tool, such as a folding anvil, and the folding mechanism can be arranged in a folding-gate module.
- a flap module facilitates Umrüst measureen. In particular, it is readily conceivable to use such a module rotated by 180 ° again to change in this way the folding direction.
- a folding plate plant for folding flat material is advantageous, which is characterized by at least one folding gate module, which can be converted by 180 ° about a direction of movement of the flat product through the folding gate module around.
- the Klappfalzmodul may have a flat gut entrance and a Flachgutausgang, of which at least one is arranged centrally with respect to the module holder of the Klappfalzmoduls.
- the flat goods input or the flat goods output which is arranged centrally with respect to the module holder, is accordingly positioned identically, so that further retooling is not necessary.
- the folding plant include at least two Klappfalzmodule that in succession, z. B. one for the front and one for the rear fold, are arranged and of which at least one can be implemented by 180 ° about a direction of movement of the slab through the respective Klappfalzmodul, so different types of folds, such as spiral fold or Z-fold can be easily realized by simple setup operations.
- the Klappfalzmodule depending on the specific design of the folding plant, so closely behind each other, that the slab must not be moved to perform the fold. The two folds are then preferably even executed almost simultaneously.
- the slab can also successively pass the two modules and be folded there in a separate step.
- both Klappfalzmodule can also be reversed sequentially. It is particularly advantageous if, in relation to the direction of movement, the flat goods input and the flat goods exit are respectively arranged centrally, so that both folding-gate modules can also be converted by 180 ° in each case.
- FIG. 1 shows a folding plant with two Klappfalzmodulen in a schematic horizontal and vertical section perpendicular to a direction of movement of the folding shutter passing through slab;
- Figure 2 shows the horizontal section of Figure 1 in an enlarged view
- Figure 3 shows the vertical section of Figure 1 in an enlarged view

- FIG. 12 converted folding-gate module
- FIG. 14 shows the arrangement according to FIG. 13 with the first one also converted by 180 °
- the folding-type folding plant 1 illustrated in FIGS. 1 to 14 comprises two folding-gate modules 5 which are sequentially traversed successively by a flat product 2 (see FIGS. 4 to 11).
- the directions of movement 3, with which the slab 2 passes through the flapper 1, is shown by way of example in Figure 1 by arrows.
- the guide of the slab 2 by the folding plant 1 comprises on the one hand in each Klappfalzmodul 5 drive rollers 8 (exemplified in the figure 3) and fixed housing guide plates 9 (also numbered in Figure 3 exemplary), which each ensure safe transport, and on the other hand, movable guides, such as folding guides 16, folding blades 18, guide flaps 19 and jaws 21st
- the guide rollers 8 are mounted on unspecified numbered drive axles. These are resiliently mounted or yielding, so that they do not cause damage even if they roll over any cards. In other embodiments, these guide rollers 8 can be axially displaced as needed, so that it is ensured that the guide rollers 8 do not roll over any cards, which could be arranged on the slab 2, and lead there to impairments.
- the folding guides 16 and the folding blades 18 are each arranged on pivot axes 17, wherein the Falz arrangementen 16 of the first Klappfalzmoduls 5 in the direction of movement 3 and the Falz arrangementen 16 of the second Klappfalzmoduls 5 against the direction of movement 3 from the Flachgutkanal, which the slab 2 at his movement passes through the folding plate 1, are pivotable.
- the jaws 21 of the respective folding works 20 are pivotable about pivot axes 29, which are arranged horizontally and perpendicular to the direction of movement 3.
- the pivot axes 17 of the folding guide 16, however, are arranged vertically and perpendicular to the direction of movement 3.
- each Klappfalzmodul 5 folding tools 10 which are formed in the present embodiment by a folding ram 1 1 or folding hammer 12 and a folding anvil 13.
- folding anvil 13 As folding anvil 13 is used in this embodiment, a region of the jaw 21 on which the folding hammer 12 can open.
- the folding hammer 12 about a pivot axis 14, which is arranged parallel to the pivot axis 22 of the jaw 21, pivotally.
- the folding hammer 12 has an elastic active surface 15, which is formed by a corresponding plastic extension.
- the elastic active surface 15 of the folding hammer 12 is in each case flat and can thus interact with the complementary, planar active surface 15 of the folding anvil 13 or the folding flap 21. Without this being shown in the drawing, a center line of these two active surfaces 15 can accordingly be formed, which is aligned in the present embodiment of the folding tools 10 according to the shape of the Falzhammers 12 and its active surface 15 parallel to the pivot axes 14 and 22 respectively and in the middle of the effective region 42.
- the pivot axis 14 of the folding hammer 12 is in this case part of a punch guide 32, wherein the folding hammer 12 is driven via a punch drive 31 (shown only schematically) for performing a falz mecanicden blow.
- a flat material 2 to be folded is correctly positioned with respect to the folding hammer 12 and the folding flap 21, wherein the guide flap 19, which is also pivotable parallel to the pivot axes 14 and 22, is swung to not hinder movement of the jaw 21 of the folding mechanism 20.
- the folding flap 21 of the first module 5 is subsequently folded over (see FIG. 5), wherein the folding guide 16 or the edge of the flat sheet 18 pointing toward the folding axis 44 of the then folded flat product 2 is level the pivot axis 22 of the flap 21 is arranged. In this way it can be ensured that the folding axis 44 is correctly positioned with respect to the effective region 42 of the folding hammer 12 and the folding anvil 13.
- folding sheet 18 or the folding guide 16 is pulled off the flat material 2 in which the former is pivoted about the pivot axis 17 (see FIG. 6). Given the division of folding guide 16 and folding sheet 18, this movement can be extremely fast.
- the fold break takes place in that the folding hammer 12 of the folding-gate module 5 strikes the folding anvil 13 formed by the folding flap 21, as shown in FIG. With the coincidence, the effective region 42 of the two active surfaces 15 of the folding hammer 12 and the folding anvil 13 and the associated surroundings 43 are defined. During this, the folding sheet 18 or folding guide 16 are moved further out of the fold of the flat product 2. As can be seen immediately lie with the fold break folding axis 44 and folding axis 41 on top of each other.
- the flat product 2 can be conveyed to the second folding-gate module 5, as shown in FIG.
- the folding hammer 12 is then opened again after the falz mecanicden blow and the jaw 21 is folded back again.
- the guide flap 19 is lowered, so that the next slab 2 (not shown here) can be fed reliably to the first Klappfalzmodul 5.
- the folding guide 16 and the folding blade 18 are pivoted back again, so that a secure guidance of the next flat product 2 is ensured, which then also, although not explicitly shown in Figure 8, already introduced at this time.
- the slab 2 is then positioned correctly with respect to the folding tools 10 of the second Klappfalzmoduls, where there is the rest position of the jaw 21 such that the Rachgut is already deflected a little down, thereby directly by nature a folding axis 44th is conditional.
- the folding flap 21 of the second flap-fold module 5 folds over, as shown by way of example in FIG.
- a fold with a folding axis 44 is correspondingly defined again, wherein this by an associated folding guide 16th as well as folding sheets 18 is positioned accordingly, wherein the folding door 21 also provides the folding anvil 13 in the second Klappfalzmodul 5.
- the folding hammer 12 of the second flap folding module 5 strikes the associated folding anvil, which again defines an effective region 42 with a corresponding environment 43, whereby previously, as can be seen in FIG. 11, the folding guide also in the second folding tile module 5 16 or the folding sheet 18 is subtracted from the slab 2, so that the blow of the folding hammer 12 is not hindered. Thereafter, the slab 2 can be easily removed folded over a Flachgutausgang 7 of the second Klappfalzmoduls 5.
- the folding hammer 12 is above - and not as in the arrangement of Figures 1 to 12 below - and the rebating hammer 12 of the second Klappfalzmodul bottom - and not as in the arrangement of Figures 1 to 12 above - arranged
- the flat gutter input 6 of the first Klappfalzmoduls 5 and the Flachgutausgang 7 of the second Klappfalzmoduls 5 are each aligned centrally, so that a conversion of both Klappfalzmodule 5 can be done easily.
