Patent ID: 8434405

Claim:
A method for setting an operation condition of a press line provided with a plurality of press machines that presses a work by raising and lowering an upper mold relative to a lower mold, a plurality of conveyance machines that conveys a work between the press machines along a predetermined conveyance route, and a control device that controls cyclic raise/lower movement of each of the press machines and cyclic conveyance movement of each of the conveyance machines along the conveyance route, the method comprising: a line speed setting step of setting a line speed indicating a work production capacity of the press line; a conveyance route setting step of setting a conveyance route of the conveyance machine so that a clearance between the conveyance machine or the work conveyed by the conveyance machine and the lower mold is a minimum; a machining speed setting step of setting a machining speed indicating a work machining capacity of the press machine; a conveyance machine phase difference setting step of setting a phase difference of conveyance movement between each of the conveyance machines so that a clearance between a work discharged from the press machine and a work delivered to the press machine is a minimum; and a press-conveyance phase difference setting step of setting a phase difference between raise/lower movement of each of the press machines and conveyance movement of each of the conveyance machines based on the conveyance route of each of the conveyance machines, the phase difference of conveyance movement between each of the conveyance machines, the line speed, and the machining speed thus set in the steps.
