Definitions

  • the invention relates to an embroidery machine, in particular a ship embroidery machine a variety of needles, a thread roller or one with thread roller rollers coupled thread roller shaft, the front thread from the thread spool over the thread roller or the thread roller roller runs to the needle, one Drive device which to the thread roller or the thread roller shaft Applies torque that the rotation of the thread roller or Thread roller rolls supported by thread tension, in order to avoid the resultant thread tension Limit tension in the front thread, or the thread roller or the Thread roll shaft, controlled by a control unit, drives the one for the stitch to deliver required front thread practically tension-free.
  • the drive device is advantageously below the needle carriage Machine frame arranged.
  • the drive device is there for service work easily accessible, which is not possible due to the limited space in the needle carriage would.
  • An advantageous embodiment provides that the drive train from the Drive device for thread roller or thread roller shaft a drive shaft and includes a transmission. This enables an advantageous, the tight Construction adapted to the space in the area of the thread spools.
  • the drive shaft expediently leads close to the front of the machine past the machine frame. This creates favorable space for the Thread spools created. But it would also be possible to use a drive shaft To drill a hole in the machine frame.
  • the gearbox can be used End of the drive shaft arranged bevel gear, which in a bevel gear engages which is arranged on the thread roller or the thread roller shaft. at the bevel gear arranged on the thread roller shaft can be the same Acting bevel gear, which also serves to drive a thread roller.
  • the transmission includes one at the end of the Drive shaft arranged gear that meshes with a gear on a Shaft sits, on which a bevel gear is arranged, which engages in a bevel gear, which is arranged on the thread roller or the thread roller shaft.
  • Shuttle embroidery machines have a variety of embroidery sites, each of which embroidering point of embroidery leads the front thread from the bobbin to the needle.
  • Fig. 1 only three of the many thread roller rollers 13 can be seen, over which the front thread to be led.
  • FIG. 3 shows how the front thread 11, also called needle thread, of the bobbin 12 over the thread roller 13 to the small thread conductor 14 and from there is guided over the large thread guide 15 to the needle 16.
  • the reference number 17 is the so-called needle carriage arranged on the machine frame 19 referred to, which contains these embroidery organs.
  • a ship embroidery machine has a large number of embroidery points. So there are also a large number of thread spools 12, thread roller rollers 13, needles 16, etc. available. When you turn on the embroidery point, the thread roller 13, too Called thread brake, via the bevel gears 40, 36 with the thread roller shaft 33 coupled, as described for example in EP 0 911 437.
  • the drive device 25 is preferably one which to the thread roller shaft 33 applies a torque which causes the rotation of the Thread roller rollers 13 supports when thread tension occurs on this. Since the Front threads 11 are wound around the thread roller rollers 13, these are at Occurrence of tension on the front threads turned, so that the thread roller shaft 33 is rotated. As Fig.1 shows, are at the ends of the Thread roller shaft 33, the thread roller brake 38 is arranged.
  • the shaft 33 will therefore often referred to as a brake shaft.
  • the drive device 25 has a motor 35 and a differential gear 27.
  • the shaft 29 can be driven by means of the differential gear 27.
  • the shaft 29 is the power transmission via a freewheel hub 28 to the gear 30. This engages in the gear 31, which sits on a shaft 32 on the other End of the bevel gear 34 is arranged.
  • the bevel gear 34 meshes with the bevel gear 36, that sits on the thread roller shaft 33. With this gearbox you can Drive device 25 a supporting torque to the thread roller shaft 33 create and so the emergence of an excessive tension in the needle threads 11 to avoid.
  • the design of the drive device 25 can in principle be as shown in FIG EP 0 795 638 is described, so that for more details on this Reference can be made.
  • Drive device 25 from the motor 35 and the differential gear 27.
  • Der Motor 35 drives a pulley 41 via a toothed belt (not shown), which is connected to the gear 45.
  • the gear 45 is the first Sun gear of the differential gear.
  • the planet gears 47 consist of two Gears 48,49, which are firmly connected.
  • the gear 48 is with the first sun gear 45 and gear 49 meshing with second sun gear 51, which is connected to the shaft 29.
  • the shaft 29 via the gears 30,31,34 and 36 supporting torque to the thread roller shaft 33.
  • This Transmission takes place approximately in the middle of the thread roller shaft 33.
  • the Drive device 25 generated torque assisted drive the Thread roller shaft 33 counter to the braking force of the thread brakes 38, which at the Ends of the thread roller shaft 33 are arranged. That on the thread roller shaft 33 Supporting torque exerted can be applied with the brake 53, of the type shown in FIG the brake shoes 52 can be seen more or less adjusted.
  • the Freewheel hub 28 also enables thread roller shaft 33 to move further or thread roller by thread pull alone if none of the drive device 25 supporting torque more on the thread roller shaft 33 or thread roller is transmitted.
  • the embroidery machine has a multiplicity of needles 16, to which the needle thread 11 from the thread spools 12 runs over the thread roller 13. If thread tension arises, so causes the tension arising in the threads 11 to rotate Thread roll rollers 13. These act on the bevel gears 40 Thread roller shaft 33 distributed bevel gears 36 and rotate them. This Rotational movement is supported by a torque of the drive device 25. This is expediently designed so that the delivered torque alone is not sufficient to rotate the thread roller shaft 33, so that only one rotation takes place when the thread is sufficiently strong.
  • the supportive Torque is applied approximately in the middle of the thread roller shaft 33.
