Definitions

  • the subject of the present invention is an embroidery machine with a horizontal arrangement of a large number of individual embroidery points according to the preamble of claim 1.
  • a main motor with a main drive shaft is arranged laterally and across the embroidery machine.
  • Cam disks for the various embroidery tool drives are attached to this main drive shaft.
  • the movement is transmitted via roller levers and other transmission means to several oscillating shafts extending along the entire machine, which in turn drive the corresponding embroidery tools in their linear movement at the many embroidery points.
  • a similar arrangement is shown and described schematically in DE 35 02 894 Figure 1.
  • the main drive shaft is arranged along the machine.
  • the corresponding cams are attached to the front and rear of this rotating main drive shaft. From these, the movements are in turn transmitted to various oscillating shafts extending along the embroidery machine, which in turn drive the corresponding embroidery tools at the many embroidery sites.
  • Such an arrangement is shown in EP 0 193 625 in FIG. 1.
  • the aim of the invention is now to push this technical speed limitation upwards and at the same time to strive for a more cost-effective solution.
  • this is achieved with an embroidery machine in that the drives of the needles and the other embroidery tools are provided approximately half the length of the embroidery machine.
  • the oscillating length of these drive shafts is generally halved, so that the limit values of the tolerable dynamic deviations only occur at higher speeds.
  • the main drive shaft which is arranged lengthways or transversely to the machine, is eliminated.
  • This concentrated center arrangement enables all of these drives to be combined in a compact drive group.
  • All embroidery tools must be precisely synchronized in their movement sequence. If the main drive assembly is arranged in the middle of the machine, there is the problem of connecting / synchronizing the embroidery tools on the front and the back of the fabric to be embroidered. In the conventional construction of the large embroidery machines with the central trench for the stenter, a mechanical connection is complex and difficult.
  • One drive motor each on the drive group for the embroidery tools in front of the stenter and a second drive motor on the drive assembly behind the stenter are precisely synchronized electrically, with the possibility of precisely definable, small temporal shifts between the movements of the embroidery tools in front of and behind the stenter in the control becomes.
  • Another new construction makes it possible to omit the central trench for the stenter.
  • This construction enables a direct mechanical connection between the drive assemblies in front of and behind the embroidery frame.
  • This construction enables a direct mechanical connection between the drive assemblies in front of and behind the embroidery frame.
  • a direct mechanical connection via corresponding drive shafts and the like namely a direct mechanical connection via corresponding drive shafts and the like, and as a further embodiment an electronic coupling can also be provided.
  • the frame of the embroidery machine is U-shaped and consists of lower, transverse supports 27, between which projecting side stands 26 are accommodated, which define a channel 28 that is open at the end.
  • Additional longitudinal beams 30 are arranged below the cheeks 29.
  • the embroidery tools are arranged on the cheeks 29.
  • a main motor 1 is arranged on the front of the frame, which also drives a drive group 2 on the front.
  • a further drive group 4, which is driven by the main motor 3, is provided on the rear.
  • the two drive groups 2, 4 act on associated longitudinal shafts 5, 6, 7, the corresponding embroidery tools being driven via the connecting rods 10, 11, 12.
  • the connecting rod 10 drives the longitudinal shaft 5 for driving the embroidery needle, while the connecting rod 11 drives the longitudinal shaft 7 for driving the thread guide.
  • the drive group 4 at the rear drives the oscillating longitudinal rod 9 for the shuttle drive via the connecting rod 12.
  • the longitudinal shaft 6 is connected to the drill 20 via a further lever, while the longitudinal shaft 5 is coupled to the needles 19.
  • the two tools work in conjunction with an opposite shuttle 21.
  • the shuttle is driven via the connecting rod 12, which acts on the oscillating longitudinal rod 9, which in turn assigns an oscillating vertical movement to the shuttle 21.
  • the transmission output shaft 31 is rotatably connected to a cam plate 22 on which an associated roller lever is supported, a double roller lever 23 being provided for the thread guide drive.
  • the drive group 4 on the rear side has a similar transmission output shaft 32, which is non-rotatably coupled to an associated cam plate 24 for the shuttle drive. It is in turn a double roller lever 25 which is coupled to the connecting rod 12.
  • the material waves 39 are now arranged vertically one above the other, the material waves 39 moving both vertically and horizontally.
  • the drive for the drill 20 is flanged onto the motor 15.
  • the elongated motor shaft 17 of the motor 15 is transmitted via a lever mechanism 18 which is coupled to a connecting rod 16 which engages a lever 33 which rotatably connects to the oscillating longitudinal shaft 6 connected is.
  • Non-rotatably connected to the longitudinal shaft 6 are further levers which drive a longitudinal tube 34 oscillating around the axis of rotation of the longitudinal shaft 6; a pawl 35 engages in the longitudinal tube 34, and depending on the position of the pawl, the drill 20 is advanced in the direction of the embroidery base 40 and penetrates it or is withdrawn.
  • the needles 19, to which a separate drive is assigned, are arranged above the drill 20, a pawl 37 likewise being connected to a similar longitudinal tube 38.
  • FIG. 4 shows an alternative to the previously described electronic coupling between motors 1 and 3, a mechanical coupling via a mechanical connecting shaft 41, only the main motor 1, for example, being present on the front side, which via a corresponding, not shown, drive shaft Drive group 2 drives on the front, and via an output shaft 42 and a spur gear, the mechanical connecting shaft 41 is driven, which in turn via a additional spur gear and an assigned output shaft drives the drive group 4 on the back.
  • individual and / or several embroidery tool drives combined into a group can be coupled to the electric motor drive by switchable couplings in such a way that the embroidery tool drives can optionally be switched on or off as desired.
  • vertical supports 43 which are also referred to as gate towers, on which the stenter with the fabric shafts is arranged and guided in a longitudinally displaceable manner.
  • the drive is also quieter and low-vibration.
  • the drive unit can be designed to be easily exchangeable, and thus embroidery machines of different outputs can be easily assembled in a modular manner.
