At least first and second adjacent parts supply tables of a parts supply apparatus are controlled so as to avoid unnecessary movement of a one of the parts supply tables not being used in successive parts supply operations, while at the same time, ensuring that the parts supply tables are sufficiently close to one another at the time of switching over between the parts supply tables to thereby reduce the duration of the switching operation. Alternately, the two parts supply tables are moved together from one position to another to maintain an interval therebetween which allows for a rapid switch-over between the parts supply tables when necessary. However, the rate at which the parts supply table in use is moved is greater than the rate at which the parts supply table not in use is moved, whereby the two parts supply tables come to a rest at different times to thereby reduce impact vibrations. |
