The automatic press material conveying system 1 of the present invention is provided with a plurality of presses 6, 7, 8, 9, and a press machine 6, 7 (installed at a predetermined distance and provided with a press die M. Press controllers 6a, 7a, 8a, 9a for controlling the 9 and 9, a material loading apparatus 11 installed at the front end of the press 6 and loaded with a plurality of materials 10, The material supply device 12 for supplying the material 10 of the material loading device 11 to the material transfer device 13 positioned at the front end, and to the presses 6, 7, 8, 9, respectively. A material transfer device (13) (14) (15) (16) installed and carried in and out of the material (10) to the mold (M), and between the material transfer devices (13) (14) (15) and (16). Auxiliary transfer device (17) (18) and (19) for delivering the material 10 so that the material installed and carried out to be carried into the material transfer device of the post-process (following process), and the material transfer device installed at the rear end ( Material discharging device 20 and the controller for discharging the material (10) to be carried out from 16) 5) is composed largely. The material supply device 12 and / or material discharge device 20 may be omitted.

3 is a process in which the present invention material transfer device 13, 14, 15, 16 loads and unloads the material 10 into the mold M of the presses 6, 7, 8, and 9. (1 cycle) is shown, the loading unit 123 is located on the left side and the carrying out unit 124 is located on the right side, and they are moved back and forth to the mold (M) located in the center under the control of the controller (5). Import and export of (10).

That is, while the press work is being progressed by the press machines 6, 7, 8 and 9 (while the material pre-loaded into the mold by the loading unit is being punched out), the loading unit 123 is a material supply device ( 12) Alternatively, the material (10) transferred from the material transfer device of the previous process is absorbed by the electromagnet at the material loading position (Sa) and then moved (L1) to the loading standby position (Sb) closest to the mold (M). At the same time, the carrying out unit 124 of the material discharging position Se moves to the discharging waiting position Sd closest to the mold M (L4) to prepare for discharging.

When one press work (mould work) is completed, the upper mold of the press machines 6, 7, 8, and 9 rises, and the ejection unit 124 waiting at the ejection standby position Sd is transferred to the mold (M). ) Up / down position (Sc) above and down (D3) to move the material (10) on the press (M) pressed by the electromagnet, the take-out unit adsorbed the material (10) 124 is moved up and down (D4) to move to the transport standby position (Sd) (L3) and move to the material transport position (Se) (L4) to transfer to the auxiliary transport device and then to the transport standby position (Sd) It moves (L4) and waits for the next release of the material.
