Title: Improvements in wire winding machines
Inventor: COLQUHOUN JOHN
IPC: H01J19/00
Filed: 1960-05-28
Abstract: 903,732. Making thermionic valve grids; coiling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 7, 1961 [July 28, 1960], No. 26334/60. Class 83 (4). A wire winding machine for producing the thermionic valve grids by winding thin wire around thicker support material fed through a winding head in the axial direction of the winding operation comprises a reciprocatable carriage and jaws carried therein for repeatedly performing a cycle of operations consisting in causing said jaws to grip the support material, drawing the same through the winding head whilst the wire is being wound and cutting off the lengths of wound support material, each cutting operation at the end of a cycle being followed by the return of the jaws into position for gripping the support material at the start of a new cycle. Support wires 7, 8 unwound from spools 4, 5 on a yoke 3 rotated about the axis of a winding head 6, serving to wind grid wire on the support wires 7, 8 and rotating at the same speed as the yoke 3, are drawn through the head 6 by a pair of jaws 21 on arms 20 pivoted at 19 on a split tube 18 rotatable in a carriage 12 moved axially by a cam 13 and linkage 14. The tube 18 is keyed to an extension of a draw tube 15 rotated by a tube 11. In operation, the jaws 21 are first closed on to the support wires 7, 8, to grip them, by the engagement of the arms 20 with a cone 16. As the carriage 12 continues to move to the right the cone 16 is pushed back along the tube 15 against a spring 23. The cone 16 then strikes a stop 24 and its movement is temporarily halted so that the jaws 21 are moved inwards to sever the support wires 7, 8. An air blast from a tube 32 blows the finished grid down the tube 11 to fall into a tray 33. A cam then moves the stop 24 out of the path of the cone 16 which is then moved rapidly to the right by an arm 27 on the carriage 12 engaging a lever 26 in turn engaging the cone. The jaws 21 then open and the carriage 12 is returned to the left. The cone 16 is also returned to the left by the spring 23 to be stopped first by the stop 24 and then, as this stop is retracted, by the lever 26 moved by a cam 25. To prevent the wires 7, 8 running back through the head 6 when they are severed, they may be engaged by spring-loaded fingers in the head or, Fig. 7, by blocks 37, one or both spring-loaded. These blocks may also serve to straighten the wire.
