A coil winding system is disclosed in which wire directing shrouds are installed in a stator where the winding is performed to direct the wire of the coils into the proper position within the stator. An automated system provides a loading gripper head for picking up an unwound stator at a pick-up position on a supply conveyor and for transferring such unwound stator to a loading-unloading position on an indexing table. A shroud gripper subsequently installs the shrouds in the stator at the loading-unloading position and the stator and shrouds are locked with respect to the table. The indexing table then transports the unwound stator to a winding position and simultaneously moves a wound stator to the loading unloading position. The shroud gripper then removes the shrouds and an unloading gripper transports the wound stator to a discharge conveyor. The loading of an unwound stator, the installation of the shrouds, the removal of the shrouds from a wound stator, and the removal of the wound stator occur while the winding is taking place so that high outputs are achievable.
A coil winding system comprising a conveyor means operating to deliver unwound dynamoelectric components on which coils are to be wound to a pick-up position and removing wound components from a discharge position, said conveyor means including positioning means operating to accurately position said unwound components at said pick-up position, indexing means providing at least two nests sequentially moving between a loading-unloading position and a winding position, separate loading and unloading gripper heads, said loading head operating through a cycle to grip an unwound component at said pick-up position and transferring said unwound component to said nest at said loading-unloading position, said unloading head operating through a cycle to grip a wound component at said loading-unloading position and transfer said wound component to said discharge position, a shroud gripper head operating through a cycle to position a shroud in an unwound component in said loading-unloading position and subsequently remove said shroud from a wound component at said loading-unloading position, and a coil winder operating through a cycle to wind a coil or coils on said component while said gripper heads operate to remove a wound component from said loading-unloading position and load an unwound component therein.
A coil winding system comprising conveyor means delivering unwound dynamoelectric components to a pick-up position and removing wound dynamoelectric components from a discharge position, a coil winder, indexing means for moving components from a loading-unloading position to said coil winder for winding coils thereon and for subsequently returning said components to said loading-unloading position, and transfer means operating through repeated cycles of sequential steps of:
A coil winding system comprising a supply conveyor operating to supply unwound dynamoelectric components to a pick-up position, a discharge conveyor operating to receive wound components at a discharge position substantially adjacent said pick-up position, said system providing a loading-unloading position in which unwound components are deposited for subsequent winding and from which wound components are removed, said loading-unloading positions being spaced from said pick-up position and said discharge position, a transfer carriage moving from a first position adjacent to said pick-up and discharge positions to a location adjacent to said loading-unloading position, a loading gripper on said carriage operating to grip and transport unwound components from said pick-up position to said loading-unloading position, and an unloading gripper operating to transport wound components from said loading-unloading position to said discharge position, said loading and unloading grippers being spaced from each other by a distance equal to the spacing between said pick-up and discharge positions, said loading gripper operating to pick up an unwound component at said pick-up position and said unloading gripper operating to deposit a wound component at said discharge position when said carriage is in said first position.
