  • a simple joint between the beam and the gripping device is used here.
  • a turning operation of the gripping device is performed so as to bring the coil gripper into the correct working position for removing the full bobbin.
  • the pivoting of the gripping device is carried out by beams in a sweeping movement of the gripping device directed obliquely upward from below.
  • the gripping device will perform a vertical offset to get into the working position for removing the full bobbin.
  • a retraction of the gripping device to the bar include, the gripping device is extended again after the turning operation on the spindle.
  • the rotation of the gripping device but also happen directly above the spindle, without the need for a retraction and extension of the Grewifvorraum.
  • the bobbin winder has a coil receptacle open at the bottom and the tube gripper has a downwardly open sleeve receptacle which can be slipped over the bobbin or the sleeve for gripping from above.
  • the tube gripper and the coil gripper can be cylindrical or conical.
  • the conical design has the advantage of a better hold of the sleeve and coil, especially when both are pneumatically operated, since the membrane adapts better to sleeve and coil.
  • each gripping unit has two indicators with which the position of the rotating device is visible through a base body. If a malfunction has occurred and the operator has to re-engage or set up a gripping unit, he can thus recognize the correct position from the outside.
  • the two indicators must be alternately set in adjacent gripping units, so that the gripping units can be positioned and the missing gripping unit can be used correctly.
  • the angle between the axis of rotation and the bobbin winder axis is equal to the angle between the axis of rotation and the sleeve gripper axis.
  • an axis of the bobbin winder and an axis of the tube gripper can be arranged at an angle to one another, which between 4 ° and 20 °, and more preferably 15 °.
