Definitions

  • the invention relates to a thread transmitter for an embroidery machine with at least one pivotably mounted thread guide lever, which is guided by a transmission arm, the movement of which is controlled by a cam disk rotating with a drivable main shaft, the transmission arm being decoupled from the cam disk.
  • It can be a thread feeder for an embroidery machine with one or more embroidery heads.
  • Each embroidery head can have one or more thread guide levers.
  • the thread guide lever is coupled to the transmission arm via a toothing.
  • the transmission arm has a projection at its free end, which is guided in a form-fitting manner in a backdrop, the inner part of which is formed by a cam disk.
  • the transmission arm can be displaced in the axial direction of the main shaft with the aid of a solenoid and can thus be decoupled from the main shaft, wherein at the same time another projection of the transmission arm engages in a fixed recess and thereby blocks the transmission arm and the thread guide lever.
  • the object of the invention is to improve a thread transmitter of the type described above so that the thread guide lever can be pivoted into any position independently of the main shaft.
  • the object is achieved in that the transmission arm is held non-positively on the cam.
  • the force can be with a spring, e.g. B. a mechanical or a gas pressure spring can be applied, but you can also use a lifting cylinder, z. B. apply a pneumatic or hydraulic lifting cylinder.
  • a spring e.g. B. a mechanical or a gas pressure spring can be applied, but you can also use a lifting cylinder, z. B. apply a pneumatic or hydraulic lifting cylinder.
  • the other position can be a predetermined position, in particular one that is suitable for thread trimming.
  • the thread guide lever can be firmly connected to the transmission arm. Furthermore, the transmission arm can have a roller for abutment against the cam disc at its free end.
  • the thread feeder shown in the drawing is intended for an embroidery machine that is not shown in detail.
  • the thread feeder includes at least one thread guide lever 1 which is pivotably mounted on an axis 2.
  • the thread guide lever 1 is arranged in the usual way in the area of an associated needle bar, not shown.
  • a transmission arm 3 is fixedly connected, which carries a roller 4 at its lower free end, which abuts a cam disc 5.
  • the cam 5 sits on a main shaft, not shown, the axis 6 is indicated.
  • the main shaft is driven in rotation. When the main shaft rotates and the transmission arm bears against the cam plate 5, the pivoting movement of the thread guide lever 1 is controlled in accordance with the curve of the cam plate 5.
  • the transmission arm 3 is held non-positively on the cam plate 5.
  • a spring 7 is provided, one end of which engages the transmission arm 3 and the other end of which is supported at 8 in a stationary manner.
  • a lifting cylinder 9 is provided, the piston rod 10 articulated on the transmission arm 3 and the other end is articulated on the abutment 8.
  • the lifting cylinder 9 has connections 11 for the pressure medium.
  • the pressure medium can be liquid or gaseous.
  • the counterforce can be adjustable or not adjustable. It can be applied mechanically with a device (not shown) for pivoting the thread guide lever and independently of the state of movement of the main shaft.
  • the roller (4) is held on the cam disc (5) by the spring via the thread guide lever (1) and the transfer arm (3).
