Apparatus for bobbin removal

Abstract

An apparatus for bobbin removal in a winding machine has a projectingly held winding spindle for winding at least one bobbin. The apparatus further has a plurality of pivoting arms which in each case have a free plug-on end and an opposite holding end. The holding ends of the pivoting arms are connected to a pivoting shaft. At least one of the pivoting arms is held, in a removal position, in alignment with the winding spindle of the winding machine for the removal of the bobbin. The pivoting shaft is oriented horizontally, and the pivoting arms are guidable in a vertically oriented guidance plane.

1 . An apparatus for bobbin removal in a winding machine, which has a projectingly held winding spindle for winding at least one bobbin, with a plurality of pivoting arms which in each case have a free plug-on end and an opposite holding end, the holding ends of the pivoting arms being connected to a pivoting shaft, at least one of the pivoting arms being held, in a removal position, in alignment with the winding spindle of the winding machine for the removal of the bobbin, the pivoting shaft being oriented horizontally, and the pivoting arms being guidable in a vertically oriented guidance plane. 
   
   
       2 . The apparatus as claimed in  claim 1 , wherein the pivoting arms are held, offset at an angle with respect to one another, on the pivoting shaft in the guidance plane, the pivoting arms being guidable alternately into the removal position. 
   
   
       3 . The apparatus as claimed in  claim 2 , wherein the angle has a size in the region of 90°. 
   
   
       4 . The apparatus as claimed in  claim 1 , wherein the pivoting arms on the pivoting shaft are designed to be pivotable clockwise and/or counterclockwise. 
   
   
       5 . The apparatus as claimed in  claim 4 , wherein the pivoting shaft is mounted rotatably on a stationary carrier and is coupled to a rotary drive, the holding ends of the pivoting arms being connected firmly to the pivoting shaft. 
   
   
       6 . The apparatus as claimed in  claim 1 , wherein a bobbin transport device is provided, which has at least one bobbin reception station, and in that at least one of the pivoting arms can be guided out of the removal position into a transfer position assigned to the bobbin reception station. 
   
   
       7 . The apparatus as claimed in  claim 6 , wherein the bobbin reception station is arranged opposite the winding machine, and wherein the pivoting arms can be pivoted through a pivot angle in the region of 180° between the removal position and the transfer position. 
   
   
       8 . The apparatus as claimed in  claim 6 , wherein the bobbin reception station is set up on the floor in front of the winding machine, and wherein the pivoting arm held pivotably between the removal position and the transfer position has a clamping mechanism for fixing the bobbin. 
   
   
       9 . The apparatus as claimed in  claim 6 , wherein the bobbin transport device has a plurality of bobbin reception stations per winding machine which form a plurality of transfer positions one behind the other within the pivoting range of the pivoting arm. 
   
   
       10 . The apparatus as claimed in  claim 6 , wherein the bobbin reception station has a movably guided bobbin mandrel which, in the transfer position, is held in alignment with the pivoting arm. 
   
   
       11 . The apparatus as claimed in  claim 6 , wherein the bobbin reception station has a bobbin chute or a running conveyor belt. 
   
   
       12 . The apparatus as claimed in  claim 1 , wherein a tube supply device is provided, which has a tube discharge station with a guide pipe, and wherein at least one of the pivoting arms can be guided into a filling position in alignment with the guide pipe. 
   
   
       13 . The apparatus as claimed in  claim 12 , wherein the tube discharge station is formed above the winding spindle in front of the winding machine, the pivoting arm being positionable below the guide pipe in the filling position. 
   
   
       14 . The apparatus as claimed in  claim 12 , wherein the tube discharge station is set up on the floor in front of the winding machine, and wherein the pivoting arm held pivotably between the filling position and the removal position has a clamping mechanism for fixing a tube. 
   
   
       15 . The apparatus as claimed in  claim 1 , wherein at least one of the pivoting arms has a push-off mechanism, by means of which at least one of the bobbin and the tube is held on the pivoting arm so as to be axially displaceable. 
   
   
       16 . The apparatus as claimed in  claim 15 , wherein the push-off mechanism has a push means and a linear drive, the push means being guided on the pivoting arm, and the linear drive being arranged in the axial prolongation of the pivoting arm.
