    专利说明:

    The invention relates to a shuttle embroidery machine with central rear-wheel adjustment according to the preamble of claim 1.
    Problem definition (problem to be solved)
    In shuttle embroidery machines, the error rate of unread loops can be influenced by finely adjusting the position of the rear carriage. This has the consequence that the position of the loop is better matched to the shuttle tip. This procedure is known for embroidering cotton, in which the position of the rear carriage must be adjusted to a greater extent.
    Prior art (prior art)
    Current embroidery machines have the ability to move the shuttle trays and thus the entire rear carriage on which they are attached. The fine adjustment takes place by means of a manual adjustment of each connection of the rear carriage to the machine frame. Since the mass to be adjusted is usually not exactly known in advance, the process must be repeated several times in order to achieve the desired result. This iterative process is time consuming and error prone.
    From DE 23 157 A1 a shuttle embroidery machine of the type mentioned is known in which, however, the rear carriage is not adjustable.
    The invention is therefore the object of developing a shuttle embroidery machine so that a central adjustment of the rear carriage in the Z direction is possible.
    To solve the problem, the invention is characterized by the technical teaching of claim 1.
    The present invention causes the almost simultaneous fine adjustment of the car width on the entire machine length. The width of the carriage is the dimension between the fully extended needle carrier and the front plane of the throat plate in the area of the stitch hole. It is thus an indirect measure of the position of looping commonly used to control adjustment.
    The fast fine adjustment leads to minimal interruptions in operation. This setting can be made manually or by means of one or more actuators. It is thus possible to reset the setpoint, which has already been determined from experience.
    In the case of a powered solution, it is possible to store this setpoint in a controller to retrieve this later to set up the machine again.
    The preferred features of the invention are listed below point by point:<tb> 1. <SEP> Central actuator (manually or by means of one or more actuators), the fine adjustment in the needle direction (Z-axis) of all rear-wheel connections takes place almost simultaneously.<tb> 2. <SEP> An actuator generates a linear or rotary motion. This is directed by means of a linkage to the individual Hinterwagenanbindungen. There, this linear or rotary movement is converted into a linear movement in the needle direction (Z-axis).<tb> 3. <SEP> The individual rear-wheel connections are adjusted by an individual actuator almost simultaneously in the needle direction.<tb> 4. <SEP> An actuator generates a linear or rotary motion. This is routed pneumatically or hydraulically to the individual rear-wheel connections. There, this pneumatic or hydraulic movement is implemented in each case a linear movement in the needle direction (Z-axis).<tb> 5. <SEP> A linear or rotary motion is generated manually. This is directed by means of a linkage, pneumatically or hydraulically to the individual rear-wheel connections. There, each linear or rotary movement is converted into a linear movement in the needle direction (Z-axis).<tb> 6. <SEP> In a first embodiment, the linear or rotary movement is implemented via an inclined plane. This allows accurate positioning in the needle direction (Z-axis).<tb> 7. <SEP> The implementation of the linear or rotary movement is carried out in a second embodiment via a finely stepped staircase. This allows a sufficiently accurate positioning in the needle direction (Z-axis).
    The resulting advantages are:<tb> 1. <SEP> Simultaneity in the range of 0 to 5 seconds.<tb> 2. <SEP> Almost simultaneous setting on the entire machine length.
    Resulting advantages over the prior art
    Since the mechanism acts on all attachment points, a misalignment is thus excluded.
    The adjustment can be determined faster because the tedious adjustment reduces to a limited effort.
    Feature of the invention is the central adjustment of the rear carriage over the entire length of the shuttle embroidery machine in the Z direction, which was not yet known.
    So far, only one setting of the rear carriage on the connection to the machine frame was possible, distributed over the length of the shuttle embroidery machine a number of individually adjustable rear truck connections was arranged, such as 16 or more.
    With the present invention, therefore, a significant simplification in the adjustment of the rear end is achieved by all Hinterwagenanbindungen be adjusted together via an associated actuator in the needle direction (Z direction).
    In a particular embodiment of the invention, it is provided that the central adjustment of the rear carriage in the Z direction takes place at the respective rear end connections, which connect the rear carriage with the Schiffchenwange.
    In a first preferred embodiment, it is provided that the adjusting gear for the central, common setting of the over the entire length of the embroidery machine extending rear carriage are arranged in the Schiffchenwange itself.
    In a second embodiment, which is also preferred, it is provided that the adjusting gear for the central adjustment of the over the entire length of the embroidery machine extending rear carriage are arranged in the rear-wheel connections, which are aligned with their longitudinal extent in the Z direction , and which provide a connection between the extending in the X direction Schiffchenwange and also extending in the X direction Hinterwagenanordnung.
    The Hinterwagenanbindungen are therefore aligned with their longitudinal extent in the Z direction and each have a common actuator, so it is possible with a single actuator to adjust all Hinterwagenanbindungen parallel to each other in the Z direction, so that with the Hinterwagenanbindungen at the free end Connected rear carriage in the Z direction is finely adjustable.
    On a machine length of for example 5 to 30 meters, the adjustment in the Z direction amounts to ± 5 mm.
    The Hinterwagenanbindungen are therefore adjustable in length. They can also be designed telescopic.
    Such, small adjustment can be achieved with a series of Einstellgetrieben, which is based on all the common idea to make a parallel adjustment of all Hinterwagenanbindungen in the Z direction so that the supported by the Hinterwagenanbindungen and aligned in the X direction rear in the Z direction, the desired adjustment path without jamming, runs parallel over its entire length.
    In the current state of the art, the adjustment of the rear carriage was carried out by separate independent adjusters, which were each arranged at each rear-wheel connection, which avoids the present invention.
    In a preferred embodiment of the centrally adjustable in the Z direction rear of a square steel profile on which the shuttle trays are attached. The metal profile should be particularly torsionally rigid and dimensionally stable.
    In a first embodiment of the invention, it is provided that a single actuator is arranged laterally on the embroidery machine, and actuated with a continuous shaft all setting gear on the mutually parallel and spaced Hinterwagenanbindungen.
    In a second embodiment it is provided that the actuator is centrally located centrally on the machine frame of the embroidery machine. Starting from this actuator, the adjusting shafts or drive rods extend to the left and to the right and thus actuate the adjusting gears arranged in each case in the rear link connections.
    In a third embodiment can be provided that two or more actuators are present, so that each setting gear is associated with an actuator.
    In principle, the central adjustment principle of the invention according to a first preferred embodiment is that a movement of a drive rod in the X direction is converted into an adjustment movement in the Z direction, which acts on the Hinterwagenanbindungen so as to the rear in the needle direction move.
    In a first embodiment of the invention it is provided to implement the transfer movement of a movement in the X direction in the Z direction, which is done via a wedge drive.
    When using such a wedge drive, it is preferred if superimposed wedge surfaces are present, so that with the actuator, the one wedge surface is moved, and the opposite wedge surface receives this sliding movement and passes in the needle direction on the rear wagon connections to the rear.
    It is preferred if the wedge surfaces are designed to be self-locking in order to avoid an unwanted displacement.
    Tapered wedge surfaces can be used instead of smooth wedge surfaces, which consequently allow a gradual adjustment in the Z direction, so as to achieve a fine pitch of the adjustment movement in the Z direction.
    In a third embodiment, it may be provided that the transfer movement from the X direction to the Z direction by other equivalent setting gear happens, such as by eccentric Abdrückvorrichtungen, by screw spindles or by pneumatic cylinders, which also acting in parallel Transfer movement from the X direction to the Z direction.
    In another embodiment of the invention, it may be provided that the setting gear are arranged directly in the rear of the vehicle, and work in the Z direction. This can be done, for example, with a screw, whose longitudinal extent is arranged parallel to the longitudinal extent of the Hinterwagenanbindungen, and which is supported in a fixedly arranged in the Hinterwagenanbindung nut, and in the rotation of the Hinterwagenanbindungen is centrally adjusted together with the attached rear.
    For the adjustment gear, there are several possibilities. The first possibility is that each screw is assigned its own actuator, and all actuators are synchronized with each other by a suitable control.
    The second possibility is instead of a controller to provide a control in which the position of the rear carriage is detected to the machine frame by a number of distance sensors and the actual signal of each distance sensor is compared with the desired signal of the distance and the difference between actual and setpoint for readjustment of each arranged at this point drive is used.
    The distance sensors can contactlessly or also touchingly detect the respective actual value of the position of the rear carriage at the respective measuring location.
    Another embodiment may provide that the screw spindles are driven by a common mechanical drive, which is derived from a central actuator.
    In this embodiment, it is important that the adjustment movement takes place directly in the Z direction, and that a conversion of an actuator in the X direction in the direction of the Z direction is not required. It is therefore a direct drive that works in the Z direction.
    When it comes to the mentioned direct drive, the common mechanical drive of the screw spindles can be done either by a common, all screw spindles bridging (driving) rack, a toothed belt or a similar equivalent drive means.
    Incidentally, the invention is not limited to allowing the actuator to act in the X direction, and implement this adjusting movement in the Z direction via a suitable adjusting mechanism.
    In an equivalent embodiment, it may also be provided to align the steep drive with its longitudinal extension in the Y direction, and to implement with a suitable transfer device, the positioning movement in the Y direction in a Z-direction acting on the rear linkage positioning movement.
    If in the present invention description of directions in the X, Y or Z direction is mentioned, this does not exclude that corresponding actuators also in the (inclined) angle to the specified X, Y and Z directions are effective, because it is important only to exert an adjusting movement in the Z direction on the rear-wheel connections, so as to adjust the attached to the rear end connections central rear in the Z direction.
    The actuators can therefore be arranged in any desired angular position to the specified coordinates X-Y-Z.
    The prerequisite is always that the adjustment direction (Z-direction) is always aligned in the needle longitudinal direction.
    However, if the needles are inclined and not aligned exactly in the Z direction, the rear carriage must also follow the longitudinal extent of the needles in its setting movement accordingly.
    The invention is not limited to the setting gear specified here. It can also be provided so-called coupling gear, which are arranged between the machine frame and the backing layers on the respective Hinterwagenanbindungen to allow a parallel adjustment of the rear carriage in the longitudinal direction to the needle extension.
    The mechanical transmission devices specified here are therefore not limited to the specified constructions, because more transmission joints can be provided to allow a parallel central adjustment of the rear carriage, starting from a central adjusting device.
    Such coupling gears are, for example, parallelogram linkage, scissor linkage or (Chebyshev or Chebyshev) Chebycheff linkage, which also solve this problem. All of these adjustment devices, which allow a parallel central adjustment of the rear carriage in the direction of the needle longitudinal axis, are included in the inventive concept.
    The object of the present invention results not only from the subject of the individual claims, but also from the combination of the individual claims with each other.
    All in the documents, including the summary, disclosed disclosures and features, in particular the illustrated in the drawings spatial formation are claimed as essential to the invention, insofar as they are new individually or in combination over the prior art.
    Insofar as individual objects are designated as "essential to the invention," "important" or "preferred," this does not mean that these objects necessarily have to form the subject of an independent claim. This is determined solely by the current version of the independent claim.
    In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

    In Fig. 1, 1a and Fig. 2, the principle of the embroidery machine 1 is shown, which consists essentially of a front cheek 2, on the front side of the needle side 3 is arranged in a conventional manner.
    Before the needle side, the web 4 passes, which can be wound on upper and lower pulp waves 5, 6. The fabric 4 associated hoop is not shown in detail and is located behind the fabric. 4
    On the opposite side, the needle side 3, a backing 7 is arranged, on which the shuttle guide 9 is arranged. This is firmly bolted to the rear 7 and together form a unit.
    In the shuttle guide 9, the shuttle sheets 10 are arranged, as will be explained with reference to the later Fig. 9 yet.
    It is now important that 17 parallel and spaced from each other Hinterwagenanbindungen 8 are arranged on a Schiffchenwange whose longitudinal extensions are aligned in the Z direction.
    It is not shown that the respective Hinterwagenanbindung 8 is formed in its longitudinal extent adjustable in the Z direction. It can also be changed by the arrangement of two telescoped and telescoped parts in its longitudinal extension.
    In Fig. 1 is shown only schematically that the X-direction corresponds to the longitudinal extent of the Schiffchenwange 17, the Y-direction extends perpendicular to the longitudinal extension of the Hinterwagenanbindungen 8, and the adjustment movement of the Hinterwagenanbindungen 8 in the Z direction in the adjustment directions 12 and 13 takes place. The Z-axis is designated by the reference numeral 11.
    In a preferred embodiment, it is provided that the right side of the respective Hinterwagenanbindung 8 is formed adjustable in its connection to the rear carriage 7 in the Z direction.
    In another embodiment of the invention, however, it may also be provided that the left connection of the rear-wheel connection 8 is formed on the Schiffchenwange 17 adjustable.
    In order to simplify the description later, it is envisaged that the right-hand connection of the rear-wheel connection 8 to the rear rail 7 extending over the entire length is adjustable in the Z-direction, specifically in the adjustment directions 12, 13.
    Fig. 1a shows the opposite perspective view of the arrangement in comparison to Figs. 1 and 2, from which further details can be removed. Here too, it can be seen that the left connection of the rear-wheel connection 8 to the rear vehicle 7 extending over the entire length of the embroidery machine is designed to be adjustable in the Z-direction at the individual rear-wheel connections.
    In the following description, when speaking of the left and right sides of the rear-end connection 8, these terms can equivalently also be used so that the left side of the rear-end connection 8 in FIG. 1 a is referred to as a fabric-facing side and the right-hand side the rear-wheel connection is referred to as the material side facing away.
    Thus, if the terms "left" and "right" are used, this means in the meaning of the drawing in Fig. 1 and Fig. 1a, the fabric facing and fabric facing away from the rear of the car 8.
    From Fig. 2, details of the central rear-wheel adjustment can be seen, from which it can be seen that in the space between the Schiffchenwange 17 and the parallel and at a mutual distance perpendicular from the Schiffchenwange extending Hinterwagenanbindungen the adjustment is arranged in the embodiment shown an actuator 15 which adjusts the setting gear 16 in the rear link 8 on the fabric facing side via a drive shaft 14 driven in common.
    3 to 5 show a first embodiment of a setting gear, wherein derived from the actuator 15 in the X direction (arrow 33) displaceable drive rod 14 is driven, which is connected via associated connections 21, 22 with a wedge carriage 19.
    The wedge carriage 19 is supported by rollers 20 on the associated Schiffchenwange 17.
    The drawing according to FIGS. 3 to 5 also shows that a plurality of such wedge carriage 19 are connected in parallel to one another via the associated drive rods 14 and the connections 21, 22 connected therebetween, and by the common actuator 15 via the drive rod 14 the arrow directions 33 are acted upon.
    In each wedge carriage 19, a central recess 23 is arranged through which engages the free end of a shaft 24, said shaft - in the exploded view of FIG. 3 - is connected to a wedge element 25.
    The lower surface of the wedge element 25 has a first wedge surface 30, which is associated with an equally inclined wedge surface 31 on the upper side of the wedge carriage 19.
    Furthermore, it can be seen from Fig. 3 that the respective wedge angle 32 is selected so that it comes to a self-locking between the two superimposed wedge elements 19, 25 in the juxtaposition of the wedge surfaces 30, 31.
    The shaft 24 is associated with a force element 28, which may be formed in a variety of configurations. In the embodiment shown, this force element 28 is designed as a cylinder 27, in the interior of which a piston 34 is displaceably driven, under the action of compressed air or hydraulic fluid.
    The piston 34 is connected to a piston rod 26, which in turn is connected to the wedge element 25, the shaft 24 and ultimately to the rear carriage 7.
    In the contracted position of FIG. 4 thus sets the piston rod 26 positively and positively on the wedge member 25, which is thus pressed with its wedge surface 30 on the opposite wedge surface 31 in the sense of self-locking, so that the two wedge elements a high give resilient connection.
    In this contracted position, the piston 34 has an adjustment distance 35 which changes in transition to the other adjustment distance 35 of FIG. 5 corresponding to the piston displacement.
    It is also added that the respective wedge carriage 19 on a tread 18 which is connected to the Schiffchenwange 17, unrolls, and is supported by means of rollers 20. However, this is only to be understood schematically. It can also be a plain bearing. Instead of the drawn rollers and balls or other rolling elements can be used.
    Fig. 5 shows the Einstellmass, from which it can be seen that the wedge carriage 19 has been moved to the left in the direction of arrow 33, whereby the recess 23 moves accordingly to the right side.
    The rear carriage 7, which is shown only schematically, has therefore been sensitively adjusted by the adjustment amount, namely the difference between 35 and 35 in the Z direction.
    The use of wedge-adjusting elements has the advantage that a particularly sensitive adjustment in the Z-direction, as in the direction of arrow 33 over a relatively large adjustment a very small adjustment movement in the Z direction by the distance 35-35 can be done.
    In contrast to the embodiment according to FIGS. 3 to 5, FIG. 6 shows that, instead of the smooth wedge surfaces 30, 31, stepped wedge surfaces 30a, 31a can also be provided, whereby an adjustment in the Z direction in the grid dimension of the stepped wedge surfaces 30a, 31a can take place.
    Fig. 7 shows a further embodiment that also a sensitive adjustment in the Z direction by adjusting the shaft 24 can be effected in that via a rotary drive movement of the actuator 15 in the direction of arrow 40, the drive rod 14 is now rotatably driven, and via associated links 21, 22 and associated pivot bearing is now rotatably connected to two mutually parallel adjustment eccentric 36 is connected, the outer circumference 38 is supported on the underside of the now formed as a stop element 25a element.
    In this way, a rotational movement of the actuator 15 is also accomplished in a sensitive adjustment movement in the Z direction on the rolling of the adjustment cam 36 on the stop element 25a.
    Fig. 8 shows a comparison with FIG. 7 modified embodiment, in which it can be seen that via a rotatably driven actuator 15, a drive rod 14 in the direction of arrow 40 and in the opposite direction, and the drive rod 14 rotatably connected to a screw 41 is, which is supported on a non-illustrated nut thread in the interior of the wedge carriage 19. In this way, the wedge carriage 19 can also be moved freely in the X direction upon rotation of the screw 41. If now the two wedge elements 25 and 19 lie on each other, there is a sensitive adjustment of the shaft 24 with the attached rear section 7 in the Z direction.
    9 to 12 show a first preferred structural embodiment of the adjustment principle according to FIG. 2.
    In a perspective view, a rear carriage 7 is shown on the needle side facing away, which is connected to the shuttle guide 9.
    With the rear carriage 7, a rear connection 8 is connected, which is formed in the embodiment shown as a transverse flange 42 which is profiled approximately U-shaped.
    The base leg of this U-profile forms in the direction of an opposite housing 44 of the adjusting device a setting gap, over which the adjustment distance 35, 35 is adjustable.
    At a distance from the base leg of the transverse flange 42, the housing 44 is arranged opposite, in which a force element 28 is arranged in the form of an actuating cylinder, the piston rod 26 is supported on the front (upper) wedge element 25.
    The wedge element 25 rests, as shown in FIG. 4, with its wedge surface on the opposite wedge surface of the oppositely disposed wedge carriage 19, wherein the mutual displacement of these two wedge surfaces is made visually recognizable by a scale.
    Further, it is shown that the wedge member 25 has a longitudinal guide by an anti-rotation 45 is disposed laterally on the wedge member 25 which engages through a longitudinal slot 47, so that the wedge member 25 is guided in this longitudinal slot 47 with its anti-rotation 45 parallel.
    It is also stated that the transverse flange 42 rests on a linear slide 43, which in turn is slidably mounted on a machine-fixed slide carrier 51.
    In the embodiments according to FIGS. 9 and 10, the drive rod 14 is fixedly connected to the connecting flange 48, which in turn is fixedly connected to the wedge carriage 19. The connection between the wedge carriage 19 and the connecting flange 48 is shown with the screw 49 in Fig. 11.
    It is further shown that on the Schiffchenwange 17 in each case at a mutual distance connecting plates 50 are attached, which are connected to the slide carrier 51.
    Thus, it can be seen from Fig. 10 and 11, that the front free end of the shaft 24 performs an adjustment movement 52 in the Z direction, and the shaft directly - not graphically shown - is connected to the rear carriage 7.
    By the parallel drive of all adjusting gears, as shown in FIGS. 9 to 11, thus all single-part gear can be adjusted together, and thus there is a common synchronous adjustment of all arranged in the respective adjusting gears shafts 24, all a common, perform precisely calibrated adjustment movement 52 directed in the Z direction.
    This is completely new and was not yet known in the prior art.
    12 shows an example of an actuator 15 for the displacement of the drive rod 14. In the illustrated embodiment, a housing 53 is fixedly secured to the Schiffchenwange 17 and has a rear fixed bearing 56 which is aligned in the Y direction.
    The protruding from the actuator housing 53 drive shaft is connected via a further pivot bearing 55, which is also aligned in the Y direction, on the drive shaft 54 which is adjustably connected by means of a clamping connector 57 with the drive rod 14 in the X direction.
    The fixed bearing 56 is connected to the holding plate 58 and disposed thereon, and the holding plate 58 is mounted on the Schiffchenwange 17.
    Fig. 13 shows the direct drive of the Hinterwagenanbindungen 8 by means of screw spindles. In this case, the actuator 15 is rotatably and fixedly connected to a pinion 61, which engages with a drive wheel 60 and this rotatably drives. The drive wheel 60 is rotatably connected to a screw 41, which is received with its external thread in the internal thread of a threaded nut 62 and can rotate freely about the shaft 24.
    The threaded nut 62 is secured against rotation, but designed to be displaceable in the axial direction. This is done for example by a longitudinal guide 64 on the machine housing 17 so that the threaded nut 62 is axially displaceable.
    Fig. 14 shows the same view as Fig. 13, with the difference that all screw spindles are interconnected by a respective rack which may be driven by an actuator according to FIG.
    Fig. 15 shows a common drive of the screw spindles or the spindle nuts via a circulating drive belt 59, wherein - as in Fig. 13 - the screw 41 is rotatably connected to the drive wheel 60. The longitudinal guide 64 is also present in this representation.
    Fig. 16 shows a so-called Kipphebelantrieb, with which it is also possible to adjust the rear carriage via a central actuator over its entire length parallel in the Z direction. The same names apply to the same parts.
    It will now be given information on the function of the rear-wheel adjustment, which apply to all rear-wheel adjustments.
    In the normal state (working state of the embroidery machine), the force element 28 is closed and the associated cylinder extended and pressurized, so that a solid, heavy-duty connection between the rear carriage 7 and the machine frame 17 is given via the inventive Einstellgetrieben.
    To adjust the rear carriage, the force element is switched powerless in a first embodiment, so that the piston used therewith or another adjusting element can be moved without substantial counterforce. The fine adjustment is fine adjusted according to the desired or metrologically determined adjustment to adjust the rear carriage to the desired setting. Thereafter, the power drive is turned on and then sets the rear carriage to the new position with respect to the machine frame.
    In a second embodiment, it is provided that the force element is completely released and moved back so that the upper wedge element or the stop element 25a lifted from the setting device (see the free gap 65 in Fig. 13) and then the actuator is actuated until the free gap 65 has reached the new setting. Thereafter, the force element is again driven against the stop so as to set the rear end heavy duty and operate with the new Einstellmass. The free gap 65 is accordingly present only when the actuator is actuated.
    A third possibility is to leave the setting gear closed under full or weakened force of the force element 28, wherein the free gap 65 remains closed. The required and desired settings on the adjusting device are then carried out with the free gap 65 closed.
    Incidentally, it is also added that the force element 28 may be formed in any desired manner; it may be a hydraulic cylinder, a pneumatic cylinder, a servomotor, a linear drive, a screw drive or the like. It is only important that a relatively large pressure keeps the connection between the machine frame and the rear end closed by counteracting the process forces sufficiently. For this purpose, the wedge elements 25 (see FIGS. 3-6, 8) or the stop elements 25a (see FIGS. 7, 13-16) are provided for applying the forces from the rear carriage 7 to the machine housing 17 to the machine housing 17 transfer.
    For the embodiments according to FIGS. 13 to 16, the kinematic reversal also applies. Instead of a rotationally driven screw 41, a rotationally driven threaded nut 62 may be present. In this case, the free gap 65 is adjusted between the screw spindle and the support surface 39.
