Abstract:
1. A servo transfer press system having a servo press that performs press working and a servo transfer device that transfers a workpiece, generating a press phase signal and a transfer phase signal that are synchronized with a master phase signal, causing the servo press to perform a press operation according to a reference press motion based on the press phase signal, and causing the servo transfer device to perform a transfer operation according to a reference transfer motion based on the transfer phase signal, the servo transfer press system comprising: a reference interference diagram generation section that generates a reference interference diagram that indicates presence or absence of interference between the servo press and the servo transfer device by using the reference press motion and the reference transfer motion; a reference interference diagram storage section that stores the reference interference diagram; an operation interference diagram generation section that generates an operation interference diagram that indicates the presence or absence of interference between the servo press and the servo transfer device by using an operation press motion and an operation transfer motion that have been input before operation; an interference presence/absence comparison-determination section that compares the operation interference diagram with the reference interference diagram stored in the reference interference diagram storage section, and determines whether or not interference will occur when using the operation interference diagram; and a phase signal relative relationship adjustment section that adjusts a relative relationship between the press phase signal and the transfer phase signal by changing one or both of the operation press motion and the operation transfer motion so that interference will not occur when it has been determined that interference will occur when using the operation interference diagram.
