    The invention relates to a shuttle embroidery machine with a laser cutting device according to the preamble of claim 1.
    A shuttle embroidery machine with laser cutting device mentioned at the outset is known, for example, with the subject matter of EP 1 958 728 B1. In this known arrangement, two embroidery machines opposite one another are arranged, in which the embroidery frames are arranged opposite one another at a mutual distance from one another and are connected to one another by a cross member. In the area of this crossbar there is arranged a laser generator which can be displaced on the crossbar and which can optionally be delivered to one embroidery frame or the other embroidery frame. The disadvantage of this arrangement is that only a single working position is provided for an embroidery frame.
    For cutting, the only laser generator must therefore be moved piece by piece along the embroidery plane, which is associated with a high level of work and long processing times. Due to the feed movements of the transport frame for the laser generator, the accuracy of the cutting process is insufficient.
    It has been found that a movable laser generator is unfavorable in terms of cutting accuracy. In addition, this document has the further disadvantage that a laser beam is generated via a rotating mirror, which is considered to be unfavorable with regard to accuracy.
    The moving rotating mirror changes the focal length and the beam length, which leads to different cutting results along the length of the fabric.
    Due to the fact that the laser optics are in connection with the rotating mirror at a short distance in front of the web of material, it is not possible in the cited publication to bring the laser beam very close to the needle puncture point. Rather, due to the design, a large distance between the focal beam and the needle entry point must be tolerated.
    [0007] DE 696 20 686 D2 (EP 0 753 372 B1) describes a laser processing device on an embroidery machine. A number of laser generators are fixedly arranged distributed over the longitudinal extent of the embroidery machine and each generate a focal beam on the fabric web at a mutual distance. The length of fabric in this arrangement is horizontal.
    The distance between the focal beams of the respective laser generators is undesirably large, and therefore it is only possible to cut relatively large-area patterns, which is felt to be disadvantageous. In addition, no precautions are taken to bring the focal beam as close as possible to the puncture point of the respective embroidery needle.
    The accepted by the prior art, undesirably large distance between the focal point on the web and the puncture point of the embroidery needle was due to the fact that the size of the needle holder and other structures in front of the embroidery needle a reduction in the distance between the focal point and needle puncture point prevented when a needle-parallel focal beam was fed.
    [0010] The invention is therefore based on the object of developing a shuttle embroidery machine with a laser cutting device in such a way that filigree cutting patterns can be formed as close as possible to the puncture point of the respective embroidery needle.
    To solve the problem, the invention is characterized by the technical teaching of claim 1.
    This makes it possible for the first time, instead of a needle-parallel focal beam, to generate a focal beam inclined at an angle to the longitudinal axis of the fabric web on the fabric, so that the parts arranged in front of the embroidery needle, such as e.g. the needle holder and other built-in parts that no longer prevent the reduction of the distance between the focal beam and the puncture site.
    With the given technical teaching there is the advantage that now a minimization of the distance between the entry point of the focal beam (focal point on the fabric web) and the needle puncture point of the respective embroidery needle is formed in that the laser beam is at an angle to the plane of the fabric web the fabric web is fed, specifically in the direction of the embroidery needle, in order to minimize the distance between the focal point of the laser beam on the fabric web side and the needle entry of the embroidery needle. Fittings on and holders for the embroidery needle no longer play a role.
    This has the advantage that very filigree patterns can be created because a distortion between the fabric and the needle puncture point is no longer significant, because by minimizing this distance, the delay is also minimized, and therefore creates distortion-free cutting patterns can be what was previously not the case with the prior art.
    In a further development of the invention it is provided that the laser generators are arranged away from the focal point on the fabric web side, and the laser beam is fed to the focal point on the fabric web at an acute angle via one or more deflecting mirrors.
    This has the advantage that the laser generators can be arranged at a relatively large distance from the throat plate and the fabric on the machine room, and in a preferred embodiment of the invention it is provided that several or each laser generator is assigned a pivot linkage, and the swivel linkage is driven by a common drive rod, so that all laser generators can be swiveled away from the fabric web in response to a specific machine command, and can also be advanced in the opposite direction towards the fabric web.
    Accordingly, it is provided in a preferred embodiment of the invention that all laser generators are driven pivotably in the direction perpendicular to the plane of the fabric by a common drive rod and a pivot linkage associated with the laser generator.
    With regard to a machine length of 16 meters, for example, it is therefore provided that between 23 and 46 laser generators are arranged distributed over this length and are pivotably driven by a common drive rod. The figures given are for information only and are not intended to restrict the invention.
    With the common swivel drive, there is the advantage that all laser generators can be precisely moved away from the material web and the material web again, without the focal beam changing on the material web.
    In a preferred embodiment of the invention it is therefore provided according to claim 5 that several or all laser generators are each arranged on a four-bar pivot linkage and the respective four-bar pivot linkage are driven synchronously by one or more linear drives.
    According to the technical teaching of claim 1, it is possible for the first time to cut particularly filigree and distortion-free patterns.
    According to a first embodiment of the invention, it is provided that the laser beams are fed to the web to be cut through deflecting mirrors.
    In a further embodiment, it is provided that generally in a spatial plane (XYZ plane) an inclined delivery of the focal beam takes place as close as possible to the puncture point of the embroidery needle on the fabric web.
    In the last-mentioned embodiment, the supply of the focal beam therefore corresponds to a conical beam space, so that the invention generally claims that an inclined supply of the focal beam can take place in a conical beam space, the tip of which is in the fabric, and this tip as a focal point as close as possible should lie at the point where the embroidery needle penetrates.
    According to a further development of the invention it is provided that the laser generators according to claims 3 and 4 are movably arranged.
    In a second embodiment of the invention it is provided according to claim 6 that the laser generators are arranged in a stationary manner, but that movable collecting lenses are provided.
    In the following, the invention is explained in more detail with reference to drawings showing several possible embodiments. Further features and advantages of the invention that are essential to the invention emerge from the drawings and their description.

    In Figure 1, the schematic diagram of a laser cutting device on a shuttle embroidery machine is shown. Such a shuttle embroidery machine has become known in various embodiments by the same applicant. Reference is made to the relevant patent applications and patents of the same applicant. All information contained therein forms the background of the present invention. The following publications are only mentioned as examples and not exhaustively:<tb> <SEP> DE20201103579U1, DE102011122422A1, DE102010021336A1, DE102010019704B4, DE102008019467B4, DE102005050482B3, DE19860770C2, DE3720907C2.
    Basically, the shuttle embroidery machine according to the invention uses a vertical plane of fabric 1, which is arranged in front of a throat plate 2, with a plurality of embroidery needles 3 in the direction of arrow 4 to the fabric 1 and away from the fabric 1 perpendicular to the plane of the throat plate are trained. Each embroidery needle 3 thus produces a needle puncture 15.
    The focus of the invention is the fact that a focal beam 61, which is generated from a laser beam 8 via a collecting lens 10, should be as close as possible with its focal point 11 to the needle puncture 15 of the embroidery needle 3. According to the invention, the cutting distance 12 to the embroidery needle 3 should therefore be minimized.
    For this purpose, the invention provides that the laser beam 8 is fed at an angle of inclination 13 and at an angle to the (vertical) plane of the fabric web 1 of the fabric web.
    For this purpose, the invention provides that a stationary or also pivotably arranged laser generator 6 is provided which carries a first mirror 23 via which a laser beam 8 is generated which is deflected by a deflection mirror 7 by a deflection angle 9, and a laser beam 8 is generated therefrom, which is focused via a converging lens 10 and then generates a focal point 11 on the material web 1 as a focal beam 61. It is now important that an angle of inclination 13 to the horizontal axis 5 is provided in this exemplary embodiment, so that the cutting distance 12 to the needle entry point 15 can be minimized.
    If the laser beam 8 were projected onto the web of material in a precisely horizontal arrangement, the cutting distance 12 would be tripled or quadrupled. The invention avoids this in that the laser beam 8 is fed at an angle of inclination 13 to the horizontal axis 5 of the fabric web 1.
    Another essential advantage of the invention is that due to the oblique deflection of the laser beam 8 with the angle of inclination 13 to the horizontal axis 5, the focal point 11 is now in an area behind which the throat plate 2 is located. This has the advantage that when the material is cut, the laser beam can no longer exit on the opposite side, which could injure a person standing there. The throat plate 2 thus serves as a glare protection and as a protective wall for a laser beam passing through the fabric web 1.
    In the exemplary embodiment according to FIG. 1, it has already been stated that the entire laser cutting device, consisting of the laser generator 6 and the laser-optical devices 7 and 10, can be arranged in a stationary manner.
    In FIG. 1, however, it is also shown as a further exemplary embodiment that the entire laser cutting device can also be pivoted away from the fabric web 1 in the direction of arrow 14 and the fabric web 1 can be advanced.
    In FIG. 1A, an exemplary embodiment modified compared to FIG. 1 is shown, in which a stationary laser cutting device is assumed. Here the laser generator 6 is fixedly attached to the machine frame on a longitudinal rail 22, and the front converging lens 10 generating the focal beam 61 is designed to be movable in the arrow directions 65. It is accordingly a swivel linkage 67 which takes over the swivel drive of the converging lens 10.
    For this purpose, the lens holder 66 is provided with an upper pivot bearing 71 on which one end of a longitudinal lever 68 engages, the other end of which is mounted in a pivot bearing 70, which in turn is pivotable in the axis of a drive rod 44 via a lever 72 is stored. The drive rod 44 is rotatably mounted in a pivot bearing 51 in the area of a bearing block 50. The rotary thrust bearing 76 located in the holder 66 compensates for the length compensation when the device is lifted. The pivot bearing 77 located on the mirror housing compensates for the rotational movement when the device is lifted.
    An approximately horizontally extending transverse lever 69 also engages the pivot bearing 71, which is in turn received in a further pivot bearing 73 on the bearing block 50 so as to be pivotable.
    In this way, by pivoting the lens holder 66, the collecting lens 10 can be pivoted up in the direction of the arrow 65 and pivoted away from the web of material 1 and fed to the web of material.
    Figures 1B and 1C show the basic principle of the present invention, namely the oblique feeding of the focal beam 61 with respect to the plane of the fabric 1 and the needle plate 2 arranged parallel to it.
    Thus, FIG. 1B shows in general that the plane of the fabric web 1 and the throat plate 2 is described by a right-angled coordinate system X / Y, and these two coordinates define the focal point 11 of the laser cutting device at the intersection.
    The Z direction extends perpendicular to the X-Y direction, as shown in FIG. 1B.
    The invention shows that the laser beam can be fed obliquely onto the fabric web 1 in the Z direction at any angle (at an angle of inclination 13) in a horizontal plane according to FIG. 1B. The angles of inclination 13 indicate the entire preferred delivery area of the laser beam.
    As possible angles of inclination, angles in the range between 2 degrees and 20 degrees are preferred. The inclined feed in the horizontal plane - as shown in FIG. 1B - thus minimizes the distance 12 (cutting distance) from the needle puncture 15 of the embroidery needle.
    FIG. 1C shows the generalization of the principle according to FIG. 1B, where it can be seen that not only an inclined feed of the laser beam 8 in a horizontal plane perpendicular to the plane of the fabric web 1 is possible, but that any inclined feed in XYZ- Direction is possible. This is shown in FIG. 1C, where it can be seen that the laser beam 8 can be fed as a focal beam 61 in a three-dimensional conical area 17 of a cone tip, the cone tip coinciding with the focal point 11 on the web 1. The inner conical area 16 is not used.
    Any desired angular feed of the laser beam 8 and the focal beam 61 obtained therefrom onto the web of material 1 in a conical area 17 according to FIG. 1C is thus possible.
    The inner, conical area 16, which is shown in FIG. 1C, is not aimed for, because there is no noticeable change in the cutting distance 12 to the needle entry 15.
    Accordingly, angular feed areas of the focal beam 61 in the area between the conical area 17 and the conical area 16 and the beam space 18, 19 defined thereby are preferred.
    All shown exemplary embodiments according to FIGS. 1, 1A and 1B show that the focal point 11 of the laser cutting device lies vertically above the needle entry point 15 of the embroidery needle 3. The invention is not restricted to this. Lateral offsets can also be provided so that the focal point 11 of the laser cutting device could also be arranged on the fabric web 1 at an angle to the needle puncture 15 of the embroidery needle 3. This was explained with reference to FIGS. 1b and 1c.
    As a first embodiment, FIGS. 2 to 5 show a laser cutting device which is arranged in a fixed and non-changeable manner on the machine frame of the embroidery machine.
    There are several laser generators 6, 6a arranged at a mutual distance on a longitudinal rail 22, and each laser generator 6 has a separate cutting point, so that it is sufficient to describe the composition of a single laser generator and its attachment to the machine frame, because the other laser generator 6a is constructed and fastened in exactly the same way.It should be noted that the laser generators 6, which are arranged parallel to one another and which are arranged on the longitudinal rail 22, are calibrated in terms of their power so that the same cutting power is achieved by each laser generator 6, 6a. Furthermore, it is specified in a preferred embodiment that the laser generators are water-cooled.
    Starting from the laser generator 6 and its attachment to the longitudinal rail 22, the mirror 23 is arranged at the exit area of the laser generator 6, which deflects it into an adjoining protective tube 24 in which the laser beam 8 is guided. So that it is guided covered.
    In the deflection area of the protective tube 24, in the transition to the protective tube 25, the deflection mirror 7 is arranged. FIG. 3 shows the further protective tube 25 which feeds the laser beam to a converging lens 10 which is arranged directly at the front end of the protective tube. Beyond the converging lens 10, the focal beam which acts directly on the fabric web 1 is generated. It is also shown in FIG. 3 that the distance 12 between the focal point 11 and the embroidery needle 3 with the needle puncture 15 located below is minimized according to the invention.
    It is also shown that there is a needle drive 26 in which the embroidery needles 3 are mounted in a displaceably driven manner.
    It can also be seen from FIG. 3 that an embroidery frame cheek 20 also belongs to the machine frame. The holder 21 is connected to the longitudinal rail 22.
    FIG. 3 shows further details of the attachment of the rigid laser cutting device according to FIG. 2. There it can be seen that the laser generator 2 is arranged on the longitudinal rail 22 and the laser beam is fed to the deflecting mirror 7 above via a first vertical protective tube 24. There the beam is deflected and fed through the protective tube 25 to the front converging lens 10, which generates the focal beam therefrom, which creates a focal point 11 on the web of material.
    It is also important here that the focal point 11 lies in the area of the throat plate 2 and is covered by the throat plate on the other side of the throat plate so that the focal beam cannot radiate past the throat plate. The throat plate 2 is thus also a protective wall against injury to a person standing on the other side of the throat plate 2, and it can therefore not be hit by the laser beam.
    Here, too, it is shown schematically that the embroidery needle 3 with its needle penetration 15 has a very small distance (cutting distance 12) from the focal point 11 of the laser cutting device.
    The protective tube 25 is firmly connected to a holding rod 26 via a holding arm 29.
    As further details, FIGS. 2 and 3 show that the thread bobbins are mounted on bobbin holders 28 and thread supplies 27 are arranged above.
    The first mirror 23 arranged next to the laser generator 6 causes a deflection by 90 degrees, while the further deflection mirror 7 arranged in the transition area between the lower protective tube 24 and the inclined protective tube 25 preferably only manages a deflection by, for example, 78 degrees so to generate the inclined focal beam aimed at according to the invention in the direction of the fabric web 1.
    The entire arrangement is otherwise fixedly attached to a machine part 30.
    The protective tube 24 is received in a clamping device on the machine part 30.
    FIG. 4 shows that suitable suction hoods 35, which are only shown schematically, are arranged at the focal points 11, that is to say at the active points of the laser cutting device. Such suction hoods can thus also be attached to the protective tube 25. For the sake of completeness, a few other machine parts are shown, such as a longitudinal beam 43 and a drive rod 44, which are arranged on the holding rod 31.
    It is shown that, starting from a central suction 32, a central line 33 is provided, into which branch lines 34 open. The vapors and gases generated at the cutting point are thus sucked off in the direction of arrow 36 and fed to the central suction 32. There they are rendered harmless by suitable filters. The feed to suction 32 takes place in the direction of arrow 45.
    FIG. 5 shows, as a further exemplary embodiment, which can be combined with the suction system according to FIG. 4 or else works on its own, that the specified laser generators are water-cooled. For this purpose there is a cooling unit 38 in which a cooling line 39 on the inlet side opens into associated branch lines 41, via which a liquid cooling medium is fed into the laser generators 6, 6a.
    The return flow takes place via the branch lines 42 and the cooling line 40 back into the cooling unit 38.
    It is added to FIG. 4 that an air flow can also be generated in the area of the protective tubes 24, 25, which air flow is designed as scavenging air. For this purpose, a purge air connection 37 is provided at the lower end of each protective tube 24.
    As a further embodiment of the invention, FIGS. 6 to 9 show that the laser cutting device can also be arranged on a pivot rod 74. The advantage of arranging such a swivel linkage is the possibility of moving the entire laser cutting device in and out away from the fabric web 1 and towards the fabric web 1.
    This leads to a considerable simplification of the operation of the shuttle embroidery machine according to the invention, because the threading of the fabric web on the embroidery frame and the threading of the embroidery threads on the embroidery needle are simplified.
    By arranging a swivel linkage 74, a swivel linkage 74 being assigned to each laser generator, there is the further advantage that when the swivel linkage 74 is swiveled away from the fabric, the work area is completely exposed and easily accessible, and the stick height is thus optimal can be used.
    FIG. 6 shows as an example that a cooling unit 38 is also provided in such an embodiment, which functions in the same way as was shown with reference to FIG.
    Here, too, the cooling medium is fed to the respective laser generator 6, but via flexible branch lines 41, 42, which can now be pivoted away from the fabric web 1 in the direction of the arrow 14. For reasons of simplicity, the length of material is not shown in FIG.
    FIG. 7 shows the same swivel linkage 74, a suction device 32 also being assigned to this arrangement, which, however, in this case has flexible branch lines 34 because the laser generator 6 is pivotably arranged on the swivel linkage 74.
    The pivoting also takes place around a central drive rod 44, which serves as a pivot bearing for the entire pivoting device.
    Further details of the pivoting mechanism emerge from FIGS. 8 and 9.
    Each laser generator 6 is accommodated between two stationary bearing blocks 50, each bearing block having a pivot bearing 51 at its upper end for the central drive rod 44 to pass through.
    In the lower region of the bearing block 50, a first bearing 52 is arranged, on which the rear end of a linear drive 49 is pivotably received. In the linear drive 49, a drive rod 48 is mounted in a displaceably driven manner.
    The free end of each drive rod 48 engages a transverse shaft 47 which is received between two bearing blocks, which in turn are mounted on the free pivotable end of an articulated lever 46.
    A further pivot bearing 54, which will be explained later with reference to FIG. 9, is arranged at the rear area.
    Starting from the pivot bearing 54, a pull lever 53 is arranged which, according to FIG. 9, is provided with further articulation devices, as shown with reference to FIG.
    In the embodiment according to FIG. 8 and FIG. 9, it is therefore important that the entire laser unit with the laser generator 6 and the protective tubes 24, 25 attached to it can be pivoted away from the web of material 1 and delivered.
    In comparison with FIG. 8, FIG. 9 shows further details.
    It can be seen from FIG. 9 that the bearing block 50 forms the upper pivot bearing 51 for the pivot bearing of the drive rod 44. Starting from the bearing block 50, a pull lever 75 is firmly connected to this, which forms a pivot bearing 54 at its outer end.
    The pull lever 53 is pivotably received in the pivot bearing 54 and is connected at its lower end to a protective hood 59 which serves as access protection so as not to get into the pivoting range of the pivot rod when the pivot rod is actuated.
    The oblique feeding of the focal beam 61 onto the throat plate and the fabric web 1 can be seen from FIG.
    In the area of a pivot bearing 58, which is arranged in the area of the protective hood 59, a further horizontal lever 56 is provided, the other end of which is received in the pivot bearing 57, which is arranged in the bearing block 50.
    It is therefore a four-bar arrangement, consisting of the following four levers, namely a hinge lever 75, the pull lever 53 and the horizontal lever 56 and the four hinge points 51, 54, 58 and 57.
    FIG. 9 also shows that a cutting knife 60 for cutting the embroidery thread is provided in front of the needle plate 2, the embroidery needle 3 being held in a needle drive 26 known per se.
    Accordingly, when the drive rod 48 is retracted in the direction of arrow 62 into the linear drive 49, the articulated lever 46 pivots about the pivot bearing 51. Thus, the articulated lever 75 lifts up, takes the pivot bearing 54 together with the pull rod 53 and lifts over the pivot bearing 58 also the horizontal lever 56, so that the entire laser cutting device with the protective tubes 24, 25 and the laser generator 6 is pivoted in the direction of arrow 14 from the fabric web.
    A pivot angle in the range of 60 degrees or more is preferred.
    There is a support 64 which fixes the entire swivel drive on the machine.
    The advantage of the invention is therefore a new type of laser cutting device with which it is possible for the first time to produce particularly filigree cutting patterns next to the respective puncture point of the embroidery needle, which was previously not possible.
