Assembly device for stacked ring

An apparatus for assembling a laminated ring, comprising:

• a component storage facility for storing a plurality of endless ring components of each of layers which are to be laminated into a laminated ring;
• component data managing means for storing component data including size data representative of at least respective circumferential length values of the ring components stored in said component storage facility;
• combinatorial trial calculation means for performing combinatorial trial calculations to combine the component data of the layers, one by one for all the layers, in said component storage facility under a predetermined combinatorial condition based on the component data of the ring components stored by said component data managing means, to generate a plurality of lamination combinatorial data representing combinations of the ring components of the respectively layers which can be assembled into said laminated ring;
• and
• unloaded product selecting means for selecting lamination combinatorial data corresponding to a laminated ring to be actually assembled from the lamination combinatorial data generated by said combinatorial trial calculation means;

• said unloaded product selecting means comprising:
• means for performing, for a plurality of times, a process of selecting a predetermined number of lamination combinatorial data as hypothetical unloading combinatorial data from the lamination combinatorial data generated by said combinatorial trial calculation means;
• and
• means for, each time said predetermined number of hypothetical unloading combinatorial data are selected, determining the degree of agreement between a frequency distribution of the size data in each layer of remaining component data which are obtained by removing the component data of each layer included in the selected hypothetical unloading combinatorial data from the component data held by said component data managing means and a predetermined target frequency distribution for each layer;
• wherein said predetermined number of hypothetical unloading combinatorial data where said degree of agreement is higher are preferentially selected as lamination combinatorial data corresponding to a laminated ring to be actually assembled.
