Stacked core assembly method and its apparatus

A stacked core assembly apparatus, which comprises a press machine, a feeder for feeding a thin-strip material into the press machine, and an indexing apparatus outputting an intermittent rotation when driven from the press machine is transmitted thereto, and a stacking member or stacked core is formed in an intermittent rotational stacking cavity device, whereas driven by the angle indexing apparatus intermittently and the angle indexing device is driven by a constant rotational speed of a driving unit of the press machine, characterized in that,

• the angle indexing apparatus is connected to the driving unit of the press machine via a non-synchronous transmitting mechanism, and an output shaft of the non-synchronous transmitting mechanism has a variable rotating speed period of time with respect to an input shaft of the non-synchronous transmitting mechanism, and thereby, a non-rotating state period of time is provided after a rotating state period of time completion and before a Feeding-Phase period of time completion, within the predetermined Feeding-Phase period of time range.
