    Description: The invention relates to a method for operating an embroidery machine with fabric cutting device according to the preamble of claim 1 and a fabric cutting device for carrying out the method.
    An embroidery machine in the context of the invention is a large embroidery machine with linearly arranged in a row Na-deln, which are positioned opposite a needle plate, wherein the thread-transmitting Schiff-chen or coils are arranged at the back of the needle plate. It is therefore a shuttle or multi-head embroidery machine.
    Therefore, the following statements relate to a shuttle big embroidery machine.
    Such a large embroidery machine with fabric cutting device has become known, for example, with the subject of DE 20 2011 103 579 U1. Characteristic of such large embroidery machines with Schneidwerkzeu gene is that flat pieces of material are applied in the desired shape on a stick bottom. If necessary, the cutting tool is brought into the area of the application layer to make cutouts from the application layer. The disadvantage of the DE 20 2011 103 579 U1, however, is the relatively poor cutting performance of the cutting tool on the application layer, because a cutable fabric guide is not given.
    EP 1 985 736 A1 describes a large embroidery machine with a cutting tool that can be exchanged for a drill. Disadvantage of this arrangement is that the cut in the application layer can be performed only in the plane of the drill, because the fastening means are arranged for attachment of the cutting device to the drilling device. Thus, the freedom to attach cutting devices is severely limited. Other disadvantages are the poor cutting performance and the suboptimal cutting edges.
    With DE 4 426 817 A1 and US 5 915 316 A1 it is known to use a laser beam as a cutting tool. By contrast, EP 1 985 736 A1 shows a heat-generating cutting tip as a replacement for a drill. Thus, the spatial arrangement of the cutting tools on a small area, namely on the line in which the drills are arranged, is limited.
    However, attempts by the Applicant have shown that the cut edges in the application layer are not optimal, because the application layer to be cut lies flat on a stab plate side counter surface, which complicates the exact depth guidance of the cutting tool in the application layer and generates fraying cut edges.
    In addition, according to DE 20 2011 103 579 U always provided that the cutting tool is arranged in Gegenüberstel- ment to the throat plate, because according to the prior art, the throat plate forms the Gegenflche for the cutting tool. However, the cutting tools in their spatial arrangement are always dependent on the presence of the throat plate and can not be used anywhere else on the fabric. Thus, it is not possible to arrange cutting tools outside of the throat plate.
    The invention is therefore the object of developing an embroidery machine with fabric cutter of the type mentioned so that a precise cut with clean cut edges in the application layer is guaranteed.
    To solve the problem, the invention is characterized by the technical teaching of claim 1.
    Feature of the invention is that the at least two-ply fabric is deformed by a mechanical positioning from its own clamping plane out in the direction of the needle side and that in this deformation region, the cutting tool cuts the fabric.
    According to the invention, the fabric is lifted locally from its clamping plane and brought into a defined cutting plane in front of the throat plate or other Gegenflche, at the point where the cutting element cuts the fabric to penetrate there into the at least one application layer and this cut or engrave.
    According to the invention therefore a local, such as mushroom-shaped deformation in the fabric web is generated in the fabric, which lifts the fabric out of the clamping plane and the cutting tool comes to meet at this point. Accordingly, a flat cut on a flat counter surface is avoided because, according to the invention, the fabric is deformed out of the flat plane towards the front of the cutting tool, at least in the cutting region of the cutting tool.
    The term "counter surface" as used herein is to be understood in general, because according to the invention the arrangement of the cutting tool is not dependent on the comparison to a throat plate. Although it is preferred that the local, mushroom-shaped deformation of the fabric panel is made in the throat plate, the throat plate forms said counterface. However, the invention is not limited thereto. The counter area can therefore also be formed by other areas of the embroidery machine. As far as the simpler description because the needle plate is described as a counter area for a cutting tool, this is not to be understood as limiting.
    With the technical teaching of the invention, a completely novel cut is proposed, because until now it was only known to arrange the cutting elements perpendicular to the throat plate and the section in the multi-layer fabric, consisting of at least one application layer and at least one embroidery bottom, flat and parallel to the throat plate level.
    This is where the invention begins, which applies a deliberate local deformation to the fabric at the point where the cutting element is used, so as to achieve a three-dimensional material deformation into which the cutting element now penetrates.
    Thus, an advantage over known cutting tools is achieved, which cut a non-opposing and supported material in free space.
    In such free-run fabrics, which work without a counter surface, there is the disadvantage that the material dodges backwards from the cutting element and unintentionally ent-removed from the cutting element during the cutting process, resulting in irregular cutting contours and fraying cut edges.
    Feature of the invention is therefore that in parallel and stretched in front of a needle plate or held before another suitable counter surface multilayer fabric only in the field of use of the cutting element before the stitch plate or the counter-surface forming fabric deformation is generated in the area of this local fabric deformation to use the cutting element.
    In a first embodiment of the invention, it is provided that the material deformation of the multilayer fabric takes place before the needle plate or other Gegenflaeche by a suitable positioning, which is preferably designed as a button-shaped or round or otherwise shaped mushroom-shaped Elément.
    It is sufficient with the positioning element according to the invention a distance in front of the throat plate or another counter surface of e.g. 1.5 mm, with a two-ply fabric having a total thickness of about 0.5 mm and each fabric layer (application layer + embroidery bottom) being about 0.25 mm.
    Accordingly, a relatively small stroke or deformation distance is sufficient to carry out the material deformation in front of the plane of the needle plate in order to bring the cutting element into use precisely in the region of this material deformation.
    Instead of using a mechanical, approximately mushroom-shaped positioning element, other solution proposals may be applied which are the subject of the subclaims.
    In a preferred embodiment, the positioning on a mushroom-shaped head on which a bolt is formed, with which it engages in an associated mounting hole in the throat plate or other counter area and anchored there.
    Instead of a simple bolt holder can be used for anchoring threaded holes with associated Ge-threaded bolt. The threaded bolt is then formed on the back of the mushroom-shaped head.
    Instead of a fixed arrangement with mounting or locking bolts and / or threaded bolt and simple adhesive or magnetic fasteners for the positioning can be provided on the needle plate or other suitable counter area. In this case, a permanent magnet is arranged in the head of the positioning, which holds itself due to magnetic holding force on the metallic throat plate or other counter area.
    It is also an advantage of the invention that the choice of the arrangement of the positioning on the needle plate or other Gegenflaeche is freely selectable within wide limits.
    In a first embodiment of the invention, it may be provided that such a positioning element is arranged approximately coaxially with the needle axis in the Unie of Nadellöcher in the throat plate.
    In a second embodiment, it may be provided that such a positioning element is arranged approximately coaxially with the drill in the line of Bohrlöcher, and in a third embodiment, it may be provided that the positioning element is attached to an arbitrary position on the throat plate ie next to, above or below the pin holes or holes.
    In a fourth embodiment, it may be provided that the positioning is independent of the An-bringung on the throat plate arranged so that it is associated with the cutting device, which is then effective outside of the throat plate.
    For the shaping of the positioning element there are various possibilities, which have in common that they produce a sufficient suppression of the multilayer material of the clamping plane at least in the field of application of the cutting tool.
    Therefore, the head of such a positioning in the plan view either round and rotationally symmetrical with rounded edges or rectangular or square, oval or rippenformig or kreisformig be formed.
    It is only important that a corresponding path position of the multilayer fabric from the clamping plane forward in the direction of the cutting tool and that the multilayer fabric otherwise rests taut on the positioning, which can be achieved in a preferred embodiment by a suitable presser ,
    A presser foot is merely an auxiliary element which can still provide an additional pressure force for the multilayered fabric on the positioning element in order to further improve the quality of the cut.
    In other embodiments, the application of the presser also completely omitted.
    Only in a preferred embodiment it is provided that the fabric presser is arranged with at least two cloth-pusher pushers in the surrounding area of the respective positioning element in order to achieve an additional taut pressing of the multilayered fabric on the positioning element.
    According to a further feature of the invention, it is provided that the positioning is far enough from the chip side, that there is a first cutting plane is formed, and the presser with his fabric pawls behind this cutting plane in the direction of the plane of the needle plate into it in order to ensure that the presser pulls the fabric tightly around the head of the positioning element so that it can not lift off the head of the positioning element.
    This ensures that the fabric always applies under bias to the positioning, because the fabric presser always ensures a tensioned state of the multilayer material. The presser is therefore a means to redirect the multilayer fabric under bias and keep curious on the head of the positioning.
    In a preferred embodiment of the invention, the positioning element is formed of a metal material, and has an approximately mushroom-shaped head which - can be provided either with a plug or clamping bolt, a locking bolt or a threaded bolt - according to the above description, to attach the positioning element to the needle plate or other machine-fixed counter surface.
    In another embodiment, it may be provided that the mushroom-shaped positioning element consists of a heat-resistant plastic material, when the cutting element is a heatable cutting tip.
    It is also possible that the cutting element operates in the manner of a punch, wherein the punch may also still be heated. The Gegenflâche formed by the positioning element is then adapted to the profile of the punch.
    Also possible is the use of a laser cutting device, which is directed to the tensioned fabric on the mushroom-shaped positioning.
    Further, it may be provided that the positioning element, which protrudes in the application in the use of a cutting element on the level of the needle plate or the Gegenflche, is formed retractable in the throat plate or the counter area when needed and non-use.
    It can be provided that the entire positioning is displaceably driven in the direction of its Leach extension, so as to lift the head of the positioning in the case of use on the clamping plane or fhhrt in case of need in a retracted position, for example, behind the plane of the needle plate or the other opposite, so that the head remains approximately flush with this plane.
    The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.
    Aile in the documents, including the summary disclosed details and features, in particular the spatial education shown in the drawings, are claimed as essential to the invention, as far as they are single or in combination with respect to the prior art new.
    In the following, the invention will be explained in more detail by means of drawings which merely represent one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

    Fig. 5: a comparison with FIG 4 modified embodiment with a slidably driven in the direction of its longitudinal extension positioning.
    In the illustrated embodiment of FIG. 1, only a schematic section through a needle plate 1 is shown, which is arranged on a machine frame 14 which is supported against the ground.
    In the area in front of the throat plate 1, the positioning element 15 according to the invention is arranged in the throat plate, which consists in the embodiment shown of an approximately mushroom-shaped head 40, on the back of a fastening pin 17 is arranged, which by an associated bore 16 in the Engraving plate 1 engages and is anchored there.
    Instead of a simple fastening bolt 17 and a locking or clamping bolt or a threaded bolt for fixing the positioning element 15 can be used.
    In the embodiment shown, a multilayer fabric 4 is shown, which consists of a total of two layers, namely a front application layer 5, which is to be cut, and an underlying embroidery base 6, which should not be injured by the cutting element 7.
    In the illustrated embodiment is shown schematically that two Stoffdrückertatzen 2, 3 of a later still be presented Stoffdrückers 37 are arranged at a mutual distance in front of the needle plate, wherein the fabric pushers 2, 3 a relatively wide horizontal distance to the approximately occupy centrally disposed positioning element 15. This ensures that the fabric 4 is guided under bias over the positioning element 15 so as to be lifted out of the clamping plane, but at the same time does not lift off the head of the positioning element 15.
    Thus, the head 40 of the positioning member 15 forms a lifted off the clamping plane Abdrückflcheche for the fabric to accommodate the Einsatzweg the cutting element 7.
    The cutting element 7 is formed in the embodiment shown as a heat cutting element, which is arranged on a displaceably driven drive rod 8. Instead of using a heat-cutting element can - in the sense of the above general description - also laser cutting device or other Schneidvor-directions are used.
    The drive rod 8 is connected via a guide 9 with intermediate levers 10, 11 and is driven by an actuator 12 which drives the intermediate levers 10, 11 in the direction of arrows 20, so as to the cutting element 7 with its tip against the application layer 5 - or put away from it.
    Furthermore, it is also shown that the fabric pawls 2.3 are slidably driven against the fabric 4. For this purpose, a Gestânge is arranged on each of the presser footprints 2, 3, which is driven via a guide 9 by an actuator 18 in the direction of arrows 20, in the cutting case, when using the cutting element 7, a bias in the fabric 4 to the positioning element 15th to create around.
    It is only schematically shown that the entire displacement drive for the fabric pawls 2, 3 via a holder 19 which is supported relative to the machine frame 14.
    Important in the invention is therefore that the positioning element 15 with its front boundary of the head 40 forms a front cutting plane 21, which lies at a distance in front of the stitch plate plane 22 and that in the direction of the Stichplattenebene 22 still behind the fabric presser plane 24, so that the cutting plane 21 occupies a greater distance 23 to the throat plate plane 22 than the distance 25 between the fabric presser plane 24 and the throat plate plane 22 comparatively.
    Through these different distances 23 and 25, it is ensured that the substance 4 is pressed onto the positioning element 15 under prestress.
    It has already been pointed out in the general description that the presser pawls 2, 3 need not be present solution-necessary. They can also be completely eliminated if the residual stress of the substance 4 is sufficient to guide the substance 4 out of the plane of the throat plate 1 via the positioning element 15 so as to form in the substance an approximately circular or mushroom-shaped substance deformation 34, which makes it possible for the tip of the cutting element 7 can attach a particularly fringe-free and precise cutting guide on the application layer 5.
    This has not been known in the prior art.
    Fig. 2 shows only the arrangement of a positioning element 15 on the needle plate 1, but also several positioning elements 15 and associated cutting elements 7 can be arranged. In the embodiment shown, the approximately mushroom-shaped positioning element 15 is mounted on the level of the throat plate 1 and projects beyond its plane in the direction of the needle side, in which case the attachment of the positioning element 15 follows in the region of the Na-dellinie 30, i. This is a connecting line through all needle holes, which are arranged on the needle plate 1.
    In another embodiment, not shown in the drawing, however, it may also be provided that one or more positioning elements 15 are provided in the region of the drill line 31 with the associated drill holes 28.
    In a third embodiment, it may be provided that the positioning element 15 lies somewhere on a displacement line 33 between said lines 30, 31, e.g. at the position 32. This means that the positioning element 15 can in principle be arranged at any point of the needle plate 1, so as to allow a controlled lift-off and a controlled material deformation 34 of the overlying material in the area of the opposing cutting element arranged there, when the cutting element is used.
    However, it has already been pointed out several times that the positioning element 15 does not have to be arranged on the needle plate 1 in order to solve the problem. As a counter surface for the cutting element can thus be used any, machine-fixed Gegenflächen that are occupied by one or more positioning elements 15 or form such.
    Accordingly, it follows from the illustration in FIG. 2 that it is not essential to solve the problem if one or more cutting elements 7 are arranged in juxtaposition to the throat plate 1. Instead of such a comparison in the area of the throat plate 1, other fastening elements can be used, if e.g. the cutting element 7 is arranged outside the needle plate 1 and there is to cut the passing material. In order to realize the concept of the invention, it is also necessary here for a deformation of the fabric 34 to take place by means of a positioning element 15 on a machine-fixed counter-surface in order to bring the substance from its usual tensioned plane into a preceding, approximately mushroom-shaped material deformation 34 and the cutting element in this Field to use.
    Incidentally, FIG. 2 also shows that in the middle region of the approximately mushroom-shaped positioning element 15 there is an exemption 26, which is e.g. is formed as a recessed blind hole to avoid that in case of failure, the tip of the cutting element engages in the positioning element 15 and thereby the cutting tip is destroyed.
    2a-2e show, respectively in plan view and in section schematized different shapes of the head 40 of the respective positioning element 15, wherein the Fig. 2a shows a rotationally symmetrical head 40 having lateral, falling edges, so a smooth interference-free Slide the fabric 4 over the head 40 to allow.
    For the purposes of this description, it is shown in FIG. 2b that the head 40a there is designed as a rectangular element with falling flanks or as a square element, and FIG. 2c shows that the head 40b can also be oval. In Fig. 2d it is shown that the head 40c can also consist of individual rib elements which also form tapered bevel edges in the profile to allow a smooth, trouble-free sliding of the fabric over the head 40c.
    Finally, FIG. 2e shows a circular ring arrangement with a central cut-out, in which case only the lateral flanks rounded off form the head 40d.
    Fig. 3 shows the top view of the application layer 5 when using the cutting element 7, where it can be seen that an approximately mushroom-shaped material deformation 34 forms due to the underlying head 40 of the positioning element 15 and thus the cutting element 7 particularly precise a cutout can make in the application layer 5.
    It is only schematically shown that a presser foot 37 is present, which has two presser pawls 2, 3 in the vicinity of the positioning element 15.
    In Fig. 2, moreover, behind the needle plate 1, the shuttle guide 27 is shown. This makes it clear that the positioning element 15 is arranged on the throat plate.
    The mushroom-shaped material deformation 34 consists essentially of two different connecting circular lines, namely an outer circular line 35 and an inner circular line 36, as is apparent in particular from FIG. 3.
    There, it can be seen that the mushroom-shaped head 40 now forms the substance deformation 34, as shown in FIG. 3, due to its rounded, rising border and the material 5 which presses thereon.
    Further, in Fig. 4 is still shown in section the exemption 26, as explained above.
    It can also be provided that the exemption 26 is filled with an elastomer to avoid damage of the cutting tip in case of trouble when penetrating the cutting tip of the cutting element 7 in the positioning element 15.
    Finally, FIG. 5 shows that the entire positioning element 15 can also be driven in a longitudinally displaceable manner, and in the illustration, the head 40 has retracted below the plane of the throat plate 1 and is therefore in the rest position for the cutting process.
    The fastening bolt 17, which is integrally connected to the head 40, is accommodated in a drive 41 which is able to displaceably drive the fastening bolt and thus also the entire positioning element 15 in the direction of the arrows 39.
    In the cutting position, the head 40 is thus moved out of the recess 38 in the needle plate 1 or another counter area and assumes a position, as shown for example in Figure 4, so as to the necessary before the stitch plate plane fabric deformation 34 for the To allow passing material.
