Abstract

A segment removal assembly (46) includes a segment removal device which automatically grasps removable segments (48, 50) of shuttle and magazine rings (8, 10) of a winding machine (2), removes the segments to a displaced position leaving segment gaps (66) in the rings and, after the interior (146) of the rings are accessed by removing and inserting a portion of a transformer core (34) from and into the interior of the rings at a load/unload station (158), the segments are replaced back into the segment gaps and resecured to remainders (52, 54) of the rings. This is accomplished using pivotal arms (110, 112, 132, 134) which engage pins (80) carried by the ring segments. Grasping the pins unlatches the segments from the remainders of the rings thus permitting the segments to be removed from the remainders of the rings. Two or more cores can be mounted to a movable common support (160) to allow one core to be wound with wire while the other core is repositioned on the common support or another core is mounted to the common support.

Claims

1. In a coil winding machine of the type including a frame supporting independently driven shuttle and magazine rings, the improvement comprising:

the shuttle and magazine rings including shuttle and magazine ring segments removably mounted to remainders of the shuttle and magazine rings;

movable ring latching elements securing the segments to the remainders of the rings, the ring latching elements each being movable between a released position, at which the segments can be removed from the remainders of the rings, and a latched position, at which the segments are secured to the remainders of the rings;

ring segments removal means for;

grasping the ring segments when said segments are at shuttle and magazine ring removal positions;

moving the ring latching elements from the engaged position to the released position;

displacing the ring segments from the remainder of the rings thereby leaving segment gaps in the rings;

reinserting the ring segments into the segment gaps, thereby closing the segment gaps;

returning the ring latching elements from the released position to the engaged position;

releasing the ring segments; and

the ring latching elements including segment grasping elements configured for engagement by the removal means.

2. The improvement of claim 1 wherein the ring latching elements include spring biased latch pins.

3. The improvement of claim 1 wherein the ring latching elements are spring biased from the released positions toward the latched positions.

4. The improvement of claim 1 wherein the removal means includes:

a base;

movable arms movably mounted to the base and having portions configured to engage the segment grasping elements; and

arm driver means, coupled to the arms, for causing portions of the arms to engage the segment grasping elements and move the ring latching elements and the segment grasping elements therewith from the latched position to the released position.

5. The improvement of claim 4 wherein the arm driver means includes a piston and cylinder drive mounted to the base and coupled to the movable arms.

6. The improvement of claim 1 further comprising a ring separator positionable between the rings.

7. A method for providing access to the interior of shuttle and magazine rings of a coil winding machine, the rings each including removable shuttle and magazine ring segments and shuttle and magazine ring remainders, comprising the following steps:

positioning the rings at predetermined shuttle and magazine ring segment removal positions;

unlatching the ring segments from the ring remainders by engaging latching elements carried by the segments and moving the latching elements so to disengage the latching elements from the ring remainders;

displacing the ring segments to provide gaps in the rings;

rotating the ring remainders until the gaps are at predetermined access positions;

accessing the interior of the rings through the gaps;

returning the ring remainders to the removal position;

replacing the ring segments in said gaps; and

relatching the ring segments to the ring remainders.

8. The method of claim 7 wherein the unlatching, displacing, replacing and relatching steps are automatically carried out under control of a controller which controls the coil winding machine.

9. The method of claim 7 further comprising the step of returning the rings to predetermined home positions after the relatching step.

10. The method of claim 7 wherein the displacing step includes the step of supporting the segments through the latching elements.

11. The method of claim 7 wherein the accessing step includes the step of:

removing a first toroidal transformer core from the interior of the rings; and

positioning a portion of a second toroidal transformer core within the interior of the rings.

12. The method of claim 11 wherein the removing and positioning steps are carried out by moving a common support, to which the first and second toroidal transformer cores are mounted, between a first position and a second position.

13. The method of claim 12 wherein the common support moving step is carried out by rotating the common support.

14. A core support assembly for supporting two or more toroidal transformer cores during coil winding operations comprising:

a common support movable between first and second positions;

first and second rotary support elements each rotatably mounted to the common support and each including a center and a curved slot extending outwardly from the center;

a core support assembly mounted to each of said first and second rotary support elements, said core support assemblies each configured to removably mount a toroidal transformer core thereto for support during winding operations at a coil winding position;

the first and second rotary support elements being positioned at the coil winding position when the common support is at the first and second positions, respectively; and

a drive peg and a center shaft, positioned at the coil winding position, sized and positioned to pass into the curved slots of rotary support elements as said rotary support elements are alternately moved to the coil winding position with the center shaft located at the centers of the rotary support elements, the drive pegs being rotatable about an axis passing through the center shaft so move the rotary support element and the core support mounted thereto about the axis at the coil winding position during coil winding operations.

15. The core support assembly of claim 14 wherein the common support is rotatable between the first and second positions.

16. The core support assembly of claim 14 further comprising means for preventing the rotation of the first and second rotary support elements relative to the common support except when one of the first and second rotary support elements is at the coil winding position.

17. In a coil winding machine of the type including a frame supporting independently driven shuttle and magazine rings, the improvement comprising:

the shuttle and magazine rings including shuttle and magazine ring segments removably mounted to remainders of the shuttle and magazine rings;

removable ring latching elements securing the segments to the remainders of the rings, the ring latching elements each being movable between a released position, at which the segments can be removed from the remainders of the rings, and a latched position, at which the segments are secured to the remainders of the rings;

a ring separator; and

ring segments removal means for;

grasping the ring segments when said segments are at shuttle and magazine ring removal positions;

positioning the ring separator between the rings;

moving the ring latching elements from the engaged position to the released position;

displacing the ring segments from the remainder of the rings thereby leaving segment gaps in the rings;

reinserting the ring segments into the segment gaps, thereby closing the segment gaps;

returning the ring latching elements from the released position to the engaged position; and

releasing the ring segments.
