Definitions

  • the invention relates to a method for embroidery of tubular sewing material according to the preamble of Claim 1 and a device for embroidering tubular sewing material according to the preamble of Claim 3.
  • the sewing machine can also be used as an embroidery machine with a controlled embroidery frame.
  • the embroidery frame is mounted on the embroidery frame carrier of such an embroidery device so as to be displaceable in the X and Y directions.
  • the embroidery device is designed as a structural unit, has an essentially L-shaped outline and lies snugly against the free arm both on the back of the sewing machine and on the front side and is detachably connected to it.
  • the surface of the embroidery device and the surface of the free arm form a common, closed work surface.
  • the object of the present invention is therefore to create a method and a device with which both embroidery of flat as well as of tubular structures is possible.
  • the sewing machine 2 shown in FIG. 1 is not explained in detail, since its structure is well known from the prior art and is irrelevant to the subject matter of the invention. In addition, only the parts of the sewing machine 2 necessary for the explanation of the invention are designated and explained in more detail.
  • the reference numeral 1 denotes the sewing machine housing, which is placed on a base plate 5 and has an essentially L-shaped shape.
  • the free arm 3 is formed on the vertical leg 4 of the machine housing 1 at a distance from the base plate 5. In its free end, not visible, the gripper is drivably mounted below the tap hole 7.
  • a needle 11 is inserted above the tap hole 7 on the needle bar 9.
  • a screen 13 is shown schematically as a rectangle.
  • a differently designed display or control unit could also be provided.
  • a trackball 15 is also provided on the machine housing 1 on the same side.
  • the assigned actuation keys are designated 16.
  • Another row of keys 17 is used to select special functions. All the elements necessary for the thread guide and the thread are not designated or shown in detail because they are not necessary for the description of the invention and its understanding and their design has no influence on the invention.
  • An embroidery device 21 connects to the front end 19 of the free arm 3. The latter also lies flush against the rear side 23 of the free arm 3 and is mechanically connected to the machine 2 by means not shown.
  • An embroidery frame carrier 25 is mounted on the embroidery device 21 so as to be displaceable in the X direction.
  • An embroidery frame 27 is fastened to the embroidery frame carrier 25 so as to be movable in the Y direction.
  • a possible design of the drive elements for the embroidery frame 27 is described in German utility model 29614512 U1.
  • the drive means for the X / Y movements of an embroidery frame are well known from the prior art and therefore do not have to be explained in detail.
  • the embroidery frame 27 can be moved in a known manner on a programmable path by means of a correspondingly designed control, not described or shown in detail. Accordingly, freely programmable patterns can be produced with the sewing machine 2 on a textile structure which is clamped in the embroidery frame 27.
  • the mutual position between the embroidery device 21 and the free arm 3 of the sewing machine, as shown in Figures 1 and 2 corresponds to the prior art.
  • the embroidery device 21 in both X and Y direction to form a space in one Distance a and b to the end face 19 and rear 23 of the Free arm 3.
  • a spacer 29 inserted between the base plate 5 of the sewing machine 2 and the embroidery device 21. This is fixed to the base plate 5 of the Sewing machine 2 and a suitably designed base 31 the embroidery device 21 connected.
  • the height h of the Spacer 29 corresponds approximately to the height of the Base plate 5 so that free access to insert tubular sewing material over the free-flying end 19 of the Freiarms 3 is guaranteed.
  • the spacer 29 comprises mechanical holding and centering means which enable a positionally accurate connection of the embroidery device 21 to the base plate 5 or to the sewing machine 2.
  • a rib-like, horizontal cam 33 and a cylindrical cam 35 with a vertical axis, which are formed on the spacer 29, serve as fastening and centering means.
  • the two cams 33 and 35 engage in correspondingly designed recesses 37 and 39 on the base plate 5 (FIG. 5).
  • the connection between the embroidery device 21 and the spacer 29 is carried out analogously.
  • a direct connection between the embroidery device 21 and the sewing machine 2 can also be established with the same means if flat textiles are to be embroidered.
  • a cam 41 which projects vertically above the surface of the spacer 29 and engages into the housing of the embroidery device 21 from below through a recess 43, interacts with a feeler 45 in order to sense the presence of the spacer 29. If the embroidery device 21 is attached to the sewing machine 2 by means of a spacer 29, the feeler 45 triggers a signal to the control device so that it only releases embroidery pattern control data for a restricted embroidery area.
  • the sensing means 45 preferably consists of a light barrier which is actuated by the cam 41 acting as an aperture.
  • the electrical power and control connections between the embroidery device 21 and the sewing machine 2 can be established in a conventional manner via an externally routed cable (not shown) or through plug connections (also not shown). The plug connections can be designed such that they are connected to the base plate 5 of the sewing machine 2 and to the embroidery device 21 at the same time as the spacer 29 is plugged together.
  • the embroidery device 21 When the embroidery device 21 is connected to the sewing machine 2 with the aid of the spacer 29, the embroidery device 21 is no longer in contact with the free arm 3, but is shifted relative to it by the distances a or b (FIG. 4). This results in a limited use of the embroidery area compared to the use of the embroidery device 21 according to FIGS. 1 and 2. Accordingly, the use of a special embroidery frame 27a is necessary, which is equipped with means for bridging the space formed between the free arm 3 and the embroidery device 21. These means consist of a bridge part 30, which is preferably formed in one piece with the embroidery frame 27a.
  • the embroidery hoop 27a is connected to the embroidery hoop carrier 25 in a known manner, whereby means for identifying the embroidery hoop can be provided in accordance with German utility model DE 29612102 U1.
  • a signal is triggered, which has the effect that the X / Y control device for the embroidery frame 27a only permits movements in a restricted area which corresponds to the size relationships of the special embroidery frame 27a.
