Casting robot comprising a weighing cell

Abstract

A casting robot ( 1 ) which includes a pivoting device for a foundry ladle ( 3 ) that is suspended by the casting robot is provided. At least one weighing cell ( 23 ) is located in the area connecting the foundry ladle ( 3 ) to the casting robot ( 1 ). The cell is used to dynamically measure an instantaneous amount of molten material present in the foundry ladle ( 3 ) or the amount of molten material poured into a casting mold ( 7 ).

1 . A casting robot ( 1 ) comprising a foundry ladle ( 3 ) suspended on a pivoting device and having a weighing cell ( 23 ) between the pivoting device and the foundry ladle ( 3 ) for weighing a metal melt contained in the foundry ladle ( 3 ), at least one weighing cell ( 23 ) is arranged, between a receiving plate ( 19 ), from which the foundry ladle ( 3 ) is suspended, and a holding plate ( 21 ), mounted to the pivoting device.  
   
   
       2 . A casting robot according to  claim 1 , wherein a load axis (A) of the at least one weighing cell ( 23 ) in a normal position with the foundry ladle ( 3 ) is horizontal, and is positioned tilted by an initial angle (X°) in reference to a vertical (V), and at a maximum travel of the foundry ladle ( 3 ), the axis (A) is tilted to the other side by an angle (Y°) after having passed through the vertical (V).  
   
   
       3 . A casting robot according to  claim 2 , wherein the initial angle (X°) is smaller than the angle (Y°).  
   
   
       4 . A casting robot according to  claim 3 , wherein the initial angle (X°) is approximately 18° and the angle (Y°) prior to complete emptying is approximately 35°.  
   
   
       5 . A casting robot according to  claim 1 , wherein the at least one weighing cell comprises three weighing cells ( 23 ) are distributed around an actual or imaginary pivoting axis (B) and are arranged between the receiving plate ( 19 ) and the holding plate ( 21 ).  
   
   
       6 . A casting robot according to  claim 5 , wherein the axes (A) of all weighing cells ( 23 ) are positioned parallel to one another.  
   
   
       7 . A casting robot according to  claim 5 , wherein the axes (A) of the weighing cells ( 23 ) are positioned at an angle to one another in each pivotal position of the foundry ladle ( 3 ).  
   
   
       8 . A casting robot according to  claim 1 , wherein weighing sensors are arranged for detecting weight changes of the foundry ladle ( 3 ).
