Since the carry-out part 27, the carry-in part 28, and the moving table 7 are symmetrical structures in the present invention, the base 3 is rotated by 180 ° when the large press material feeder 1 is installed. Even if it is installed and used so that the carry-out part 27 is located on the right side, there is no problem at all. That is, the position can be changed left and right.

In the present invention, the carry-out part 27 leads the material adsorption part 29 and the unloader 27a to linearly reciprocate in the direction of the arrow V1 and V2 as illustrated in FIG. 1, and the carry-in part 28. Is a linear reciprocating motion in the direction of the arrow (V3) (V4) to guide the material adsorption portion 30 and the loader (28a), the moving table (7) the arrow in the lower portion of the carrying out portion 27 and the loading portion (28) The material 6 received from the carry-out part 27 is transferred to the carry-in part 28 while linearly reciprocating in the directions V5 and V6, and the material adsorption parts 29 and 30 are unloader 27a. And by the loader 28a, the adsorption, loading and unloading of the raw material 6 is achieved while moving up and down H1, H2, H3 and H4.

In the present invention, when the material 6 is taken out, the material adsorption portion 29 is driven by the unloader 27a while the carrying-out portion 27 moves forward with the material adsorption portion 29 and the unloader 27a (V1 direction). ) Rises slightly higher than the height of the material on the punched mold (in the H1 direction) (rises to a preset height) and then enters the large press mold of the previous process (enter the set forward distance) to the unloader 27a. When the pressed press material is adsorbed while descending by the material, the material detecting sensor 8a detects this, and the controller 31 recognizes the material adsorption and operates the unloader 27a to set the material adsorption part 29 to a set height. When it rises, the carry-out part 27 is reversed by the set distance (V2 direction), and the adsorbed raw material 6 will be located on the upper plate 32 of the moving table 7 which is advanced toward the carry-out part 27 direction. .

In this state, the material adsorption portion 29 is lowered to the set distance by the lowering operation (H2 direction) of the unloader 27a to remove the material on the upper plate 32 of the moving table 7 and then unloader ( As a result of the rising operation (H1 direction) of 27a), the rising and returning moves immediately for the next detachment or waits for a while.

The moving table 7 receiving the detachable material is moved in the direction of the arrow (V6 direction) by the interaction of the pinion 124 and the rack 122 that is fixed by the servo motor 123 and the guide of the LM guide. It moves and stops at the lower part of the material adsorption part 30 of the loading part 28 which is advanced in the V3 direction.

Subsequently, the material adsorption part 30 descends by the controller 31 by the lowering operation (H4 direction) of the loader 28a of the loading part 28 to adsorb the transferred material. When the controller 31 detects this and inputs it to the controller 31, the controller 31 determines that the material is adsorbed and moves the loader 28a upward (H3 direction), thereby increasing the material adsorption part 30 and the material 6. At the same time, the moving table 7 returns to the carry-out part 27 direction V5 to wait for the next material transfer.

When the adsorbed material rises, the servo motor 26 of the carry-on part 28 operates to move to the mold of the large press in the post-process (V4 direction), and then the material is loaded (loaded) onto the mold and then returned. They will either wait for the next time to bring in the material or until the punch is complete.

When the carrying-in part 28 imports a raw material into the metal mold | die of a post process large press, a process progresses in the reverse order of the above-mentioned carrying out process.

For example, the carry-in part 28 guides the loader 28a and the workpiece | work material adsorption | suction part 30 to which the workpiece | work 6 was adsorbed, and moves to the loading direction (V4 direction) by the raising operation (H3 direction) of the loader 28a. When the material adsorption portion 30 and the material 6 rise slightly higher than the mold height (ascend to a predetermined height) and then enter the large press mold of the post-process (enter the set forward distance), the loader 28a The material 6 is removed from the mold 6 while being lowered (H4 direction) by the lower part, and the material is injected onto the mold, and the controller 31 moves the loader 28a up (in the H3 direction) to move the material adsorption part 30 to the set height. When it rises, the carry-in part 28 is returned to the set distance (V3 direction), and prepares to carry in next material or waits for a while.

The moving table 7 is a linear transfer using a linear moving table according to the working environment when transferring the received material to the carrying-in portion 28, or rotated by using a rotary moving table as shown in FIG. Or, reverse transfer is performed using an inverted moving table as shown in FIG. 24.

If the rotation of the material is required to replace the linear moving table with the rotary moving table, if the reversal is required to attach the reversal means 165 of the removable / attached structure on one side of the linear or rotary moving table.
