    Description: The invention relates to a shuttle embroidery machine with a shuttle guide and an improved embroidery image according to the preamble of patent claim 1.
    In large embroidery machines, the shuttle guides are combined in a stick and each shuttle guide consists essentially of a guide body, which is usually made of plastic, on each of which a shuttle track is arranged, which usually consists of a metal material.
    The shuttle is driven on the shuttle track in the longitudinal direction and contains in a known manner a coreless bobbin with the shuttle thread (rear thread).
    It is known to interrupt the shuttle in the transverse direction by a needle channel which is open in the direction of the shuttle. The embroidery needle moves in and out of the needle channel in a direction perpendicular to the direction of movement of the shuttle.
    The embroidery needle transports the needle thread (front thread) into the needle channel in this process and forms a loop during the return stroke (moving out of the needle channel) through which the shuttle is passed so as to devour the shuttle thread with the needle thread.
    When driving through the shuttle through the loop formed from the needle thread, the shuttle travels in the longitudinal direction of the shuttle until the rear of the shuttle approximately coincides with the upper limit of the needle channel and thus releases the entire needle channel, from which the entanglement is then released Towards the fabric level.
    During the movement of the shuttle back before reaching the transverse needle channel, a loop forms on the shuttle back.
    Before the back of the shuttle has reached the right side of the needle channel, a loop of the needle thread forms on the back of the shuttle and the shuttle is driven further towards the needle channel. The loop formed with the needle thread on the back of the boat forms a residual loop.
    In the prior art, there was the disadvantage that it could not be ensured that the remaining loop resting on the back of the boat under the tension of the needle thread could be safely pulled under the boat in order to be drawn into the needle channel under the action of the needle thread tension.
    [0010] This problem is described in DE 331 546 B. However, the only aim is to ensure that the shuttle train runs as straight as possible. However, there is no mention of correcting the problem described below.
    In many cases it happens that the remaining loop gets stuck on the back of the boat and therefore there is an inadmissible increase in the thread tension of the needle thread, which is undesirable.
    Such thread tension peaks, which are caused by the needle thread getting caught on the back of the shuttle, impair the quality of the embroidery image. The thread tension adversely affects the last embroidery knot formed because it was formed under excessive thread tension, which affects the overall appearance of the embroidered fabric.
    Another disadvantage is that with a stuck thread there is a risk that the needle tip of the embroidery needle collides with the stuck thread in the needle channel, runs onto it, punctures it or even cuts it.
    As a result, there is a risk that the needle thread itself tears or gets under such high tension that the undesired condition adversely affects the embroidery image.
    The entanglement between the needle thread and the shuttle thread is uneven due to this disadvantageous appearance and leads to a restless and unclean embroidery pattern.
    The quality of the embroidery is measured by how the thread distribution is on the back and in such undesirable phenomena, the embroidery image on the back of the fabric is adversely affected.
    The invention is therefore based on the object of developing an embroidery machine with a shuttle guide of the type mentioned in such a way that an improved, high-quality embroidery image is produced.
    To achieve the object, the invention is characterized by the technical teaching of claim 1.
    It is a feature of the invention that the shuttle track has a lowered clearance in the inlet area in front of the needle channel, which extends below the level of the shuttle track and frees the shuttle track in this area.
    This exemption makes it possible for the first time to withdraw the needle thread without undesirable tensile stresses in the needle channel without the risk that the remaining loop of the needle thread gets stuck on the back of the boat and thereby an undesirable increase in thread tension during the state of pulling in the remaining loop in the needle channel arises.
    CH 711 458 B1 [0021] In a first embodiment of the invention, it is provided according to claim 2 that the exemption is designed as an inclined plane. This inclined plane extends below the plane of the shuttle train and opens into one side edge of the needle channel.
    By arranging such an inclined plane, the tread of the shuttle is interrupted and modified by the exemption just before the needle channel, which has the advantage that pulling the remaining loop into the needle channel is facilitated because the remaining loop no longer falls The back of the boat can get caught. The remaining loop slides undisturbed from the back of the shuttle into the release and is pulled into the needle channel without problems and without undesirable thread tension maxima because of the release according to the invention.
    Instead of the formation of an exemption as an inclined plane that extends below the level of the shuttle, there are alternative designs. Instead of designing the exemption as a slope, namely as a level descending towards the needle channel, it is also possible to provide a step level, i.e. an exemption, which forms a plane formed parallel to the shuttle, which is arranged below the shuttle. Claims 3 and 4 define embodiments with a step level.
    Claim 5 describes a further embodiment, where the exemption is designed as a lowered, spherical surface, i.e. it lowers both in the direction of the shuttle track and in the transverse direction.
    The invention is not limited to the arrangement of straight levels as exemptions. These levels can also be contoured, e.g. be convex or concave.
    Accordingly, it can also be any free-form surfaces that can be described in such a way that an exemption is arranged starting from a transverse edge that lies at a certain longitudinal distance in front of the right-hand boundary of the needle channel.
    This exemption should therefore lead into the needle channel without the risk that - as in the prior art - the remaining loop either gets stuck on the back of the boat or in the intermediate area between the underside of the shell of the boat and the surface of the boat track. The shuttle train is therefore exempted in this area according to the invention.
    The length of the exemption in the direction of the longitudinal axis of the shuttle, starting from the entry into the needle channel, should be chosen so that it corresponds to the distance of the boat tail from the lower channel edge at the time the loop falls from the back of the boat.
    This makes it much easier to pull the remaining loop into the needle channel because there is no longer any fear of the remaining loop getting stuck on the rear of the shuttle.
    The time depends on the relative interaction of the shuttle speed on the shuttle and the thread guide. The thread guide pulls the needle thread back onto the front of the fabric, and the time at which the thread guide does this determines the time when the remaining loop falls off the rear of the shuttle.
    This typically takes place when the back of the shuttle is about 5 to 6 mm in front of the right border of the needle channel.
    In a further development of the present invention, it can also be provided that the shuttle track runs straight into the needle channel, i.e. the exemptions according to the invention on the side of the shuttle can be omitted, but the exemptions according to the invention mentioned in relation to the shuttle are now arranged on the rear and underside of the shuttle.
    Here, too, separate protection is required for the formation of the rear shell of the boat on the bottom side, because the arrangement of one or more exemptions in this area also facilitates the retraction of the remaining loop.
    The invention is therefore not limited to the arrangement of an inclined plane on the back of the boat (bottom side).
    Instead of an inclined plane, all the above-mentioned exemptions, which were described on the shuttle side according to the invention, can also be arranged on the bottom side of the shell of the shuttle. The invention also relates to a combination of both versions.
    In addition to the described exemptions on the track and boat, it is useful to provide the back of the boat with a sliding edge that facilitates the immersion of the fallen loop in the needle channel on the back of the boat.
    Of course, all of the above-mentioned exemplary embodiments, whether exemptions on the shuttle side and / or exemptions on the bottom side of the shuttle shell and / or also sliding radii on the rear of the shuttle, can be combined with one another in any manner.
    CH 711 458 B1 [0038] Insofar as individual items are described as “essential to the invention” or “important”, this does not mean that these items must necessarily form the subject of an independent claim. This is determined solely by the current version of the independent claim.
    In the following, the invention is explained in more detail with the aid of drawings showing only one embodiment. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.
    [0040] It shows:

    In Fig. 1, a guide body 1 is generally shown, which preferably consists of a plastic material on which a shuttle track 2 is arranged, which preferably consists of a metal material. The shuttle track 2 serves as a running surface for a shuttle 10 which is displaceably driven on the shuttle track 2 and which is driven in the arrow direction 8 and in the opposite direction.
    The guide body 1 preferably consists of a plastic material and has a fastening foot 3 on the back. The guide body 1 is also referred to as a “finger”, and four guide bodies 1 are each arranged in a block and form a stick.
    In the drawing of Fig. 1, a needle thread 6 is formed by immersing the embroidery needle 5 in the needle channel 4 in that a loop 7 is formed when the embroidery needle 5 is withdrawn in the direction of the arrow 13.
    1, the shuttle 10 is driven in the direction of the arrow 8 and passes through the loop 7 thus formed, which slides over the top surface of the shell 11 of the shuttle 10 and in the direction of arrow 42 to the rear and over the rear of the shuttle 14 onto the shuttle track 2 falls.
    2, the fabric level 45 is indicated, which coincides approximately with the paper level according to FIG. 2.
    The back of the fabric is therefore the drawing side of the paper plane in Fig. 2. The paper plane of Fig. 2 forms the back of the fabric plane 45, and on the back of the drawing plane of Fig. 2, the embroidery pattern would be visible.
    CH 711 458 B1 During the transition from the sequence of movements in FIG. 2 to FIG. 3 it can be seen that the loop 7 should fall down over the rear side 14 of the boat as tension-free as possible.
    After the loop size 7 in Fig. 2 is larger than the remaining loop 7 ', which results in Fig. 3 because of the pulling of the needle thread, it is tension-free and the remaining loop 7' is now to be drawn into the needle channel 4.
    4 shows such an operation in an enlarged view according to the prior art. It can be seen that the remaining loop 7 'could get caught on the rear of the boat 14 because the wrap 23 formed there on the rear of the boat 14 finds frictional resistance or inhibition or the rear of the boat is straight or not designed as a sliding radius, so that there is a risk that a Retraction of the remaining loop 7 'in the direction of the needle channel 4 is hindered.
    This process is shown in Fig. 5, wherein in Fig. 5 the thread tension over time according to the invention and according to the prior art is shown.
    A first curve maximum 15 of the thread tension results when the thread begins to fall down from the back of the boat, as shown in FIG. 2.
    At position 16, the thread has only a low thread tension because it comes into the position shown in FIG. 3.
    The prior art now shows that when the remaining loop 7 'gets caught on the rear of the boat 14, an undesirable second curve maximum 18 occurs, which is to be prevented in any case and from which the arrangements according to the prior art suffer.
    The second curve maximum 18 arises only when the remaining loop 7 'sticks to the back of the boat 14, and there is also the risk that with this undesirable tension curve according to FIG. 6, the thread length 28 protruding into the needle channel 4, caused by the Needle eye 25 passes through, is damaged by the needle tip 9.
    [0055] Therefore, the needle thread is impaled or even completely severed.
    6 shows, moreover, that the wrap 23 should now fall completely from the rear of the boat in the position shown, but this does not happen.
    The bottom edge 22 of the shell 11 of the shuttle 10 has no distance from the plane of the shuttle track 2, and the loop 23 is only detached at the entry point 24 into the right boundary 47 of the needle channel 4, as a result of which only a short distance 48 is overcome.
    Characteristic of the prior art is accordingly that a relatively large thread length 27 must be accepted as a detachment of the wrap 23 from the back of the shuttle 14, because only a complete retraction of this detached thread length 27 in the entry point 24 shortly before the right limit 47 happens in the needle channel 4.
    According to the invention, this long thread length 27, which hinders the detachment process of the remaining loop 7 ', is to be decisively shortened.
    If the remaining loop 7 'is prevented from getting stuck according to the prior art (FIG. 6), then the second curve maximum 18 is also avoided, and instead the first curve maximum 15 overflows into a straight line, specifically from position 16 via position 17 directly to position 19, where after position 19 the third curve maximum 20 connects.
    The third curve maximum 20 according to the prior art and the invention is achieved when the thread has been completely pulled to the front and is stretched again.
    5 shows the advantage of the invention, where it can be seen that the second curve maximum 18, which is caused by an unwanted snagging of the wrap 23 on the rear of the boat 14, is now avoided according to the invention.
    The needle thread 6 is pulled out according to FIG. 3 in the direction of the arrow 12, at the same time as the retraction movement in the direction of the arrow 13 of the embroidery needle 5. This is shown in FIG. 3.
    Another cycle then follows in the diagram according to FIG. 5, which follows at position 21. A complete cycle takes about 100 milliseconds, while the diagram shows only the first 50 milliseconds of such a cycle.
    6 also shows that after the thread length 28 has passed through the needle eye 25 there is another thread piece 26 which disappears in the needle channel, and the circle with a cross shown in FIG. 6 shows that it is is an arrow direction perpendicular to the plane of the drawing.
    7 to 9 now show a first preferred embodiment of the invention, where it can be seen that an exemption 30 is arranged in the inlet area 46 of the shuttle track 2 in the direction of the right boundary 47 of the needle channel 4, which in the exemplary embodiment shown is designed as an inclined surface with a linear lowering in the direction of the right boundary of the needle channel 4.
    CH 711 458 B1 This inclined surface accordingly has a straight incline 36 in the direction of the right-hand boundary 47 of the needle channel 4.
    A run-in area 46, which opens obliquely into the needle channel, is thus defined, which considerably facilitates pulling the remaining loop 7 'into the needle channel 4. The right boundary of the exemption 30 in the transverse direction to the shuttle track is indicated by the transverse edge 38.
    However, the invention is not limited to a linearly sloping inlet area 46 in the direction of a boundary 47 of the needle channel 4. Instead of a linearly sloping inlet area, the inlet area can also be curved or not linearly sloping. It is therefore only important that, starting from the transverse edge 38, there is a linear or non-linear lowering in the form of an inlet area 46 falling in the direction of the needle channel.
    8 and 9 further details can be found. In Fig. 8, the shuttle train 2 'belonging to the prior art is shown in broken lines.
    It can be seen that pulling the remaining loop 7 'into the needle channel is now made considerably easier because the needle thread can slide freely under the bottom side of the shell 11 of the boat 10 due to the exemption 30 according to the invention, without the surface of the boat track stands in the way or obstacles in the area of the underside of the boat play a role. The very small exemption 30 'belonging to the prior art between the upper side of the shuttle track 2' and the underside of the shuttle 10 is now decisively increased according to the invention, as is evident from the larger exemption 30.
    The entry point 24, which according to the prior art was arranged next to the right boundary 47 on the needle channel 4, now moves to the right and forms the entry point 24 'according to the invention. This clarifies that when the thread 6 is pulled in the direction of the arrow 12, the entry point 24 'moves to the right in the direction of the arrow 50, i.e. more and more thread comes under the boat without fear of getting caught on the back of the boat 14. The thread is, so to speak, peeled off from the back of the boat, due to the exemption 30 according to the invention.
    Thus, the thread length 28 'drawn into the needle channel 4 is also significantly increased, as can be seen from the comparison of FIG. 6 to FIG. 9.
    At position 37, the position of the last link is also given, which is only shown symbolically. At this point, the undesirable changes in the embroidery pattern arise, which are caused by the second curve maximum 18 according to the prior art, because the needle thread is held at this point and an inadmissible tension on the needle thread 6 at point 37 according to the prior art of the second curve maximum 18. This is now avoided according to the invention.
    In Fig. 8, the prior art is still entered by way of example, with the reference numeral 2 ', where it can be seen that the prior art differs from the first embodiment of the invention with respect to the exemption 30 by an inclined plane . In the prior art, this inclined plane was not present and there was only a narrow passage gap on the bottom side of the boat shell.
    10 shows in perspective the exemption 30 according to the invention as an inclined plane in the first embodiment.
    Fig. 11 shows a second embodiment, which is characterized in that an exemption 31 is provided as a parallel plane to the level of the shuttle 2, but this parallel plane is separated by a transverse edge 38 from the shuttle 2 and placed lower .
    12 shows, as a third exemplary embodiment, that it is not necessary for the solution to form the inclined plane or the exemption 30, 31 over the entire transverse extent of the shuttle track 2. In some other cases, it is sufficient to arrange a partial exemption 32 as a recessed plane below the shuttle track 2, the partial exemption being formed by a longitudinal edge 39 and the transverse edge 38. The longitudinal edge 39 divides the width of the shuttle train approximately in the range from 1: 1 to 1/4: 3/4.
    Of course, the transitions at the edges 38, 39 are fluid into the exemption 31, 32 below, so that suitable curve radii are present there.
    A third embodiment according to FIG. 13 provides an entangled exemption 33, which consists in that the longitudinal edge 39 is parallel to the plane of the shuttle track 2 and also forms a straight line with the shuttle track, but starting from this longitudinal edge 39 level with the shuttle track there is a further transverse edge 38 which is also in the plane of the shuttle train.
    On the opposite side there is an inclined edge 40 which forms the boundary of the needle channel 4 and which also runs in opposite to the longitudinal edge 39 on the plane of the shuttle track, also inclined with an inclined edge 41 in the direction of the needle channel 4.
    Instead of such an interlocking exemption 33, all other exemptions can be used, as mentioned in the general introduction to the description.
    CH 711 458 B1 It is also possible to combine all different embodiments according to FIGS. 10 to 13 in any way.
    14 shows the equivalent exemplary embodiment in comparison to FIGS. 10 to 13, where it can be seen that the inclined exemption 30 to 33 can also be arranged on the underside of the boat 10.
    The bottom edge 22 of the boat is thus provided in the area of the rear of the boat 14 with the exemptions 30 to 33 according to the invention, as was only explained in the exemplary embodiment according to FIG. 14 with reference to FIG. 10.
    Here, too, the example is characterized in that even in the state in which the shuttle 10 according to FIG. 14 is before the needle channel 4 is crossed, the residual loop 7 'can be pulled into the needle channel without tension, because Any inhibition on the back of the boat 14 due to the special shape of the bottom of the boat is avoided.
    15 shows, as a further exemplary embodiment, which can be combined in any way with the exemplary embodiments according to FIGS. 10 to 14, that in isolation or in any combination with the exemplary embodiments according to FIGS. 10 to 14, additionally - or in isolation - a rounded sliding edge 44 can be arranged on the rear bottom edge 22 on the back of the boat 14. Here, too, the tension-free pulling in of the remaining loop 7 'under the boat in the direction of arrow 42 is promoted without the risk that it will get caught on the back of the boat or on its sole.
    The direction of arrow 43 only shows a section through the thread, which is already drawn in under the bottom edge 22 of the boat in the direction of the needle channel 4.
    Fig. 16 shows schematically the falling of the remaining loop in the direction of arrow 42 down, and exactly at this stage, which is shown in Fig. 16, the transverse edge 38 for the formation of the exemption 30 to 34 should be arranged, from which the exemptions should begin on the running surface of the shuttle and / or on the bottom surface of the shuttle.
    This clarifies how the length 49 of the exemption in the direction of the shuttle 2 should be chosen. It corresponds to the distance between the rear of the shuttle 14 and the right boundary 47 of the needle channel 4 at the time according to FIG. 16, where the remaining loop 7 'falls from the shuttle shell 11 onto the shuttle track 2.
    This measure (length of the exemption 49) should therefore represent the preferred measure of the exemption 30 to 34 according to the invention in the longitudinal direction of the shuttle.
