Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A control device for controlling a plurality of machines including industrial robots, which are provided in a single production line comprising: means for producing a prior notice of actuation for each of said machines a predetermined period of time before the actuation of each of said machines; means for calculating a total amount of voltage drops caused by the actuations of said machines to which the prior notices of actuation have been issued; means for detecting whether the total amount of voltage drops is lower than a predetermined allowable value; means for determining drive order and drive timing of said machines according to priorities which have been given to said machines, respectively, when it is detected by said determining means that the total amount of voltage drops exceeds the predetermined allowable value; and means for driving said machines according to outputs of said determining means.
Claim 2
Dependent Claim
145 words
