ASSEMBLY DEVICE FOR STACKED RING

摘要

An assembly device for stacked ring, wherein stacking combination data formed by combining the ring parts for each layer with each other is prepared by a computer (13) when the ring parts (4) for each layer for assembling a stacked ring (3) is output from a part storage house (10), the target frequency distribution of the peripheral length values of the ring parts (4) for each layer is set, the stacking combination data including the ring parts grouped in the class having the large error of an actual stock frequency against a target frequency is selected in a layer having the maximum error of the actual stock frequency distribution against the target frequency distribution, and the ring parts (4) for all layers corresponding to the selected stack combination data are output from the part storage house (10), whereby the state of distribution of the size data of the ring parts (4) for each layer in the part storage house (10) can be maintained continuously in the state capable of assembling more stacked rings (3) and, thus, the stable productivity of the stacked ring (3) can be assured continuously.
