    专利说明:

    The invention relates to a shuttle embroidery machine with an embroidery gate according to the preamble of claim 1.
    Shuttle embroidery machines are characterized in that an embroidery gate in dimensions of z. B. is moved in a size of about 2 m × 30 m by associated actuators to generate the embroidery pattern. The weight of an embroidery frame of this size is around 1000 kg.
    In order to generate precise embroidery patterns, it is necessary to move the high weight of the stick frame of up to 1000 kg sufficiently dynamically in two spatial axes x / y with high acceleration in order to achieve precise guidance of the stick frame.
    Basically, in industrial shuttle embroidery machines, a carrier material must follow a desired embroidery pattern through constantly coordinated X / Y movements. For this purpose, the carrier material is taken up in an embroidery grid, which is also called a grid in technical usage and is clamped above and below as well as left and right.
    In order to be able to drive this X / Y movement with sufficient accuracy, the gate is defined in its position horizontally and vertically via linear guides and is moved along dynamically.
    According to the prior art, it is known to design the machine frame in two parts, namely in a larger, lower machine frame, on which a smaller, upper machine frame is placed.
    The lower machine frame is usually poured from concrete or another heavy material or made of a metal material for vibration reasons, while the upper, placed on the lower machine frame machine frame made of a lighter material, such as. B. consists of a frame structure made of metal profiles.
    So far it has been customary to guide the embroidery gate in the Y direction (that is the direction of the vertical) by linear rails arranged on the machine frame side.
    According to the prior art, it is known to arrange a number of mutually spaced, parallel linear rails on the upper machine frame and it is also known to attach an equal number of linear rails to a guide on the lower machine frame of the embroidery gate extending over both machine frames in the Y-direction.
    After the linear rails aligned in the Y direction take over a guide of the gate, a horizontal limitation of the gate takes place in its position.
    It was also known to arrange linear guides on the lower machine frame, each linear guide consisting of at least one guide carriage and also to arrange further linear rails aligned in the Y direction on the upper machine frame. Each linear rail was assigned at least one slide for longitudinal guidance in the Y direction.
    The disadvantage of the prior art is that a first type of linear rails was used for the linear guide of the gate in the Y direction on the lower machine frame and a second type for the linear rails arranged on the upper machine frame. It is known to use the linear rails on the Train the lower machine frame offset by an X offset to the linear rails on the upper machine frame. This had the advantage that short linear rails could be used that were easy to assemble. At the same time, there was the disadvantage that the Y-displacement path of the embroidery gate was limited to the short linear rail and therefore only a single guide carriage could be arranged per linear rail.
    Thus, the guiding properties of the stick gate in the Y direction were impaired and the arrangement of several guide carriages on the respective Y linear rail was not given.
    Another disadvantage of the prior art was that you had to align the linear rails on the upper machine frame in the same direction in alignment with the linear rails on the lower machine frame, which was associated with a high alignment effort.
    The invention is therefore based on the object of developing a shuttle embroidery machine with an embroidery gate in such a way that an improved linear guide of the embroidery gate is provided in relation to the machine frame.
    To solve the problem, the invention is characterized by the technical teaching of claim 1.
    In a first preferred embodiment, it is provided that the linear rails now extend over the entire height of the stick gate over both machine frames arranged vertically one above the other and are formed from a continuous, uniform metal material.
    In a second embodiment of the invention it can be provided that the respective linear rail z. B. is interrupted in the middle and coupling links are arranged there, which ensure that the two linear rail parts of the upper and lower machine frames are aligned and connected to one another, merging into one another.
    It is also possible to use multiple split linear rails instead of two split linear rails, but the focus of the invention is the knowledge that the linear rails preferably extend continuously and in alignment over the entire height of the stick, which is the case with the prior art was not the case.
    In conventional large embroidery machines, the length of such linear rails is in the range of 4 meters.
    In the prior art, an offset in the X direction and even an offset in the Z direction between the linear rails on the upper and lower machine frame was accepted, although this simplified the design effort and made assembly easier because more accessible but conditional on the other hand, that only a single gate connection per linear rail according to the prior art had to be arranged.
    By the arrangement according to claim 1, the guiding properties of the embroidery gate in relation to the subdivided machine frame are significantly improved. The other guide arrangements can now be arranged in the middle areas between the upper and lower machine frames, which was not possible in the prior art because an interruption of the linear rails was consciously accepted in this area.
    Because of the continuous Y-rails of the stick gate, there is therefore the possibility of not only providing two slide guide systems arranged at a distance from one another, but also, for example, to attach additional slide guides in the middle area of the frame, which was previously the case with the prior art because of the in Purchase of the X and Z offset between the divided linear guides was not possible.
    In this way, even very high gate weights can be transferred to the machine frame in a vibration-free and precisely guided manner.
    The invention makes use of the knowledge that it is important for the arrangement of vertically continuous linear rails to bring the machine level lying next to the material level of the lower and the upper machine frame in the vertical direction lying one above the other in an aligned match, so that these are aligned one above the other and on this now vertically continuous plane the respective linear rail can be screwed on in its entire vertical extent or fastened in some other way.
    In the prior art, there was always an offset between the next machine level of the lower machine frame compared to the vertical plane on the upper machine frame, which prevented a continuous fastening of a linear rail.
    This is where the invention comes in, which now for the first time provides a continuous linear rail on the two vertically stacked machine frames and offers the advantage that not only an upper and lower slide guide is present, but that between the two known upper and lower ones Slide guides still further slide guides can be arranged, which is only possible with continuous linear rails.
    The invention is not limited to the number of linear rails used and arranged parallel to one another. With smaller shuttle embroidery machines it may be sufficient to use the gate for two linear rails at a mutual distance from the vertical guidance of the embroidery gate.
    In large stick gates that work with divided machine frames, the advantage of the present invention comes into play that instead of the offset linear rails on the upper and lower machine frame, continuous linear rails can now be used.
    With large gate lengths of z. B. 10 to 30 m, 6 to 17 linear rails arranged parallel to one another can be arranged, with each linear rail not only being assigned an upper and lower slide guide, but also one or more central slide guides can be arranged in the space between the upper and lower slide guides, which is only possible thanks to a continuous linear rail extending in the Y direction. The other slide guides bridge, so to speak, the horizontal dividing line between the upper and lower machine frame, which was previously not possible.
    If there are several attachment points for the respective linear rail, it is now possible for the first time to design the overall structure of the gate as a lightweight construction, because an improved guide is available and thus the gate can be designed with a total weight reduction.
    So it is possible within the scope of the present invention to reduce the conventional gate weight from 900 kg to 1000 kg to 600 kg with the same size.
    The undesired natural vibrations of a stick frame according to the invention are also significantly reduced by the arrangement of a large number of additional support points.
    Because the invention dispenses with an X offset and a Z offset, the space for the embroidery gate is reduced by the offset in the X direction required according to the prior art, so that a reduced overall height and a reduced one The overall width of the embroidery machine results.
    You also have fewer components, because because of the use of continuous linear rails, it is no longer important to manage linear rail pairs in the warehouse during assembly and the supply of spare parts.
    The use of a continuous linear rail also shortens the assembly effort when assembling an embroidery gate, since a parallel adjustment of several interdependent, mutually divided linear rails is not necessary.
    In the following, the invention is explained in more detail with the aid of a drawing that shows only one embodiment. Further features and advantages of the invention that are essential to the invention emerge from the drawing and its description.

    In Figures 1 and 2, a gate 1 is shown according to the prior art. The gate 1 consists of three mutually spaced frames, namely two outer frames 2, 3 and a middle frame 4. All frames 2-4 are rectangular frame constructions, the outer frames 2 each consisting of parallel vertical legs 5, 6, which are each connected to one another by horizontal legs 7, 8.
    The middle frame 4 consists of vertical legs 9, 10, which are connected to one another by associated horizontal legs 11, 12.
    The frames 2-4 are attached to a divided machine frame, the lower part of the machine frame 16 extending from an increased weight mounting part, which is to absorb the vibrations, while the upper part of the machine frame 15 is designed as a frame structure, with a number of towers are present, which are indicated in Figure 1 in dashed lines.
    It is important that the gate 1 is guided by a number of linear rails, the lower part of the gate 1 being guided in parallel in the Y-direction by linear rails 13 arranged on the lower machine frame 16, while the upper part of the gate 1 is guided on the upper machine frame 15 is guided displaceably in the Y direction by other linear rails 14 arranged there.
    The guidance within the linear rails 13, 14 takes place in each case by carriages 17, a single carriage 17 on the lower machine frame 16 being indicated in FIG. 1 for the sake of simplicity. The other parts shown in broken lines are also designed as slides 17.
    According to Figure 2, the upper machine frame 15 was offset by the Z offset 26 to the lower machine frame 16, which prevented that the linear rails 13, 14 were formed continuously. They were mounted offset from one another by the Z offset 26 on the respective levels of the machine frame 15, 16 and, according to FIG. 1, there was also an X offset 22, 23, 24.
    So they were aligned neither in the Z nor in the X direction.
    Because of the relatively short length of the respective linear rails 13, 14 given as a result, it was only possible to arrange only a single slide guide with a slide 17 on the machine frame. It was not possible to use several carriages in the area of these linear rails 13, 14 with divided machine frames.
    The linear guidance of the gate 1 took place in the arrow directions 18, and the upper fabric shaft 19 was attached to the upper part of the gate 1, the fabric shaft 19 having stub axles 20 which engage in assigned bearing points on the gate 1.
    The upper fabric shaft 19 is assigned the lower fabric shaft 21, which has the same bearing with stub shafts 20.
    Because of the offset 22-24 and 26 shown in Figures 1 and 2, it was not possible to make the linear rails 13, 14 continuous. This is where the invention comes in, which, according to FIGS. 3 to 5, now provides for the linear rails 13, 14, which were previously divided into two, to be designed continuously as a single linear rail 33.
    However, the term "single continuous" linear rail is only to be understood in such a way that the linear rail 33 is either continuously formed as a part or it is interrupted, for example, in the central area and has appropriate connecting or coupling means that ensure that the coupled parts of the linear rail 33 extend in an aligned vertical axis, so that further guide means (e.g. slide 17) for the sliding guidance of the gate guided on the linear rails 33 can also be arranged in the connecting area.
    Thus, the invention provides that the linear rails 33 extend approximately over the entire height of the gate 1 and form continuous gate guides, which now for the first time has the advantage that further carriages 37 also in the intermediate area between the upper and lower carriage 17 can be arranged.
    The carriages 37 are connected to the gate 1, and FIG. 5 shows only by way of example that in each case a further carriage 37 is arranged in the space between the conventional carriage 17.
    The invention is not restricted to this. Provision can also be made for more than one carriage 37 to be arranged at a mutual distance on the linear rails 33.
    The same reference numerals and explanations apply to the same parts in FIGS. 3 to 7 as were given in FIGS. 1 and 2 with regard to the prior art.
    FIG. 3 shows a first exemplary embodiment in which the assembled machine frame is formed from two machine frames 15, 16 arranged one above the other and separated from one another by a parting line 29. The lower machine frame 16 consists of a heavy cast material such as e.g. a concrete or a cast metal, while the upper machine frame 15 can be formed from a lighter material, in particular metal profiles. A number of towers 34 are provided distributed over the length of the embroidery machine, FIG. 3 merely showing the side view of a single tower 34.
    Some of the towers 34 shown have in their lower part a stand 36, with which the upper machine frame 15 is placed on the parting line 29 to the lower machine frame 16. The drive part 38 for the shuttle side is arranged above the stand 36. The first exemplary embodiment according to FIG. 3 shows that the linear guide 33 according to the invention is now screwed continuously to the upper and lower machine frames 15, 16 or is releasably fastened in some other way. The fastening points 41 are only shown schematically here.
    To compensate for a possibly uneven fastening surface in the region of the lower machine frame 16, support rails 39 are fastened, which are fastened on the one hand to both the upper machine frame 15 and the lower machine frame 16. To facilitate assembly, the support rail 39 has a lower, angled leg 40 on which the linear guide 33 rests. The linear rails 33 are connected to the support rail 39 at least in the area of the lower machine frame 16.
    Because of the better dimensional accuracy of the upper machine frame 15, the linear rails can be fastened there directly via the fastening points 41.
    Thus, the respective linear rail 33 extends essentially over the entire height of the machine frame 15, 16 and also bridges the parting line 29 between the upper and lower machine frame 15, 16. This makes it possible for the first time to arrange additional slides 37 for the sliding guidance of the gate 1, not shown, on the linear rail 33 in the area of the parting line 29.
    As a further exemplary embodiment, FIG. 4 shows a lower machine frame 16, which consists for example of metal profiles. This is a machine frame 16 that is lighter than that in FIG. 3 and is connected via a horizontal separating line 29 to an upper machine frame 15 which has a number of towers 34. A linear rail 33 with fastenings 41 is attached to each individual tower 34 or to every second or third tower 34. It is not shown that guide carriages or the like are arranged on the respective linear rail 33. Each guide carriage has rollers, which roll in the associated profile of the linear rail 33 so as to be longitudinally displaceable. Instead of a guide with rollers, other longitudinal guides can also be used, in particular sliding guides or ball guides.
    Each guide carriage is connected to the gate 1. Thus, the gate 1 is guided vertically displaceably on a plurality of vertically displaceable guide carriages 17, 37 on the linear rails 33.
    Because of the better dimensional accuracy of the lower machine frame 16, the fastening of the linear rail to a support rail 39 can be dispensed with in this embodiment. The linear rails are connected there directly to the lower machine frame 16 via the fastening points 41.
    In FIG. 4, the drive part 35 for the needle side is also shown on the right-hand side.
    FIG. 6 shows the advantage of the invention, where it can be seen that the two machine frames 15, 16 are arranged one above the other in such a way that they result in a mounting plane aligned parallel to the material plane 25, so that it is possible for the first time to use a linear rail 33 to be fixed in alignment over both machine frames 15, 16.
    This results in the further advantage that further carriages 37 can now be used in the space between the upper and lower carriage 17 for linear guidance of the gate in the Y direction.
    The gate 1 can thus be built more easily because it is guided precisely, and the vibration properties are improved because, because of the arrangement of further carriages 37, there is now better and lower-vibration guidance.
    It is assumed here that the two machine frames 15, 16 have a parting line 29 so that they are placed on top of one another in the area of this parting line.
    In addition to the aforementioned X offset 22-24, the invention also reduces the offset 27 shown in FIG. 1 in the Y direction, which is also called the Y offset for short.
    While the prior art according to FIG. 2 provides machine levels 30, 31 offset from one another, the invention now uses a continuous vertical mounting level 32 which extends over the two machine frames 15, 16 in order to provide a continuous mounting level for the linear rails 33 enable.
    FIG. 7 shows the top view of the gate 1 according to the invention, where it can be seen that the linear rails 33 are now vertically continuous and extend approximately over the entire height of the embroidery gate. There is no longer any mutual offset between the linear rails 13, 14 of the upper and lower machine frames 15, 16.
    If an exemplary embodiment with separately profiled gate frames 2, 3, and 4 was described in the preceding description of the figures, the invention is not limited thereto. In another embodiment, the gate construction can be made from large-area bent sheet-metal parts. The frame-shaped gate mentioned in the preamble of the patent claim is then not composed of profile rails, but rather forms a continuous and / or divided sheet metal part.
    A bent sheet metal part is a closed sheet metal sheet which, if necessary, is made rigid by means of rolled-in beads or flanges.Such closed frame parts, designed as closed sheet metal parts, are preferably used for the two outer frames 2, 3 in the exemplary embodiment according to FIG. The reason for this is that, for reasons of accident protection, it is intended to prevent an operator from reaching through the frames 2, 3 arranged at the edges and injuring himself while the machine is running. The middle frame 4 is usually designed as an open frame part in order to enable the operator to set up the machine.
