The invention relates to an automatic wire arranging device with feedforward measurement. The automatic wire arranging device comprises a gantry bracket and further comprises tension wheels, a wiringarranging device, an I-shaped wheel and the like which are arranged on the gantry bracket. The wiring arranging device is arranged between bracket bodies on the two sides of the gantry bracket throughan electric sliding table, and two photoelectric switches for measurement are arranged at the bottom of the electric sliding table, the photoelectric switches are utilized to conduct positioning in advance through a certain measurement method, and accordingly, the wiring arranging device makes a reverse action in time. The automatic wire arranging device is accurate in positioning, reversing is conducted in time, manual intervention is not needed in the whole process, the problems of manual wire arranging in the actual production process and the problems that during automatic wire arranging,measuring points are inaccurate and the wire arranging device is not reversed in time, and consequently, the same layer of cables are loose and are stacked are solved effectively, and the production efficiency is improved.
