Abstract

The present invention automatically sets an optimum combination for efficiently picking up parts. A plurality of possible combinations of parts to be picked up when the parts are picked up by a plurality of heads, are input to a RAM 4 in the form of a table as quantity conditions and pick up conditions represented by identifiers and part symbols, and are sequentially provided to a CPU 1. The CPU 1 assigns the parts to be actually placed, which are included in the part table, to the part symbols; generates an evaluation table; registers an optimum combination whose evaluation is the highest to the RAM 4; removes that combination from the part table; reassigns the remaining parts in the part table after the removal operation to the part symbols of the search conditions; and repeats the generation of the evaluation table, registration of the optimum combination, and the removal of the combination from the part table. As a result, the CPU 1 sequentially extracts all of the parts included in the initial part table as the optimum combinations, and sequentially registers these combinations to the RAM 4. Consequently, data (parameters) of optimum combinations of parts to be picked up can be automatically obtained based on the part table. This data is used for a part mounting program instead of manually input combination data.
