The suction rod 371 is a hollow shaft having an inner diameter of 1 mm and an outer diameter of 2 mm.

Thus, the suction bar 371 is formed with a vacuum suction force provided from the vacuum providing unit 360.

The photo sensor 400 which measures the magnitude | size value of the processed thin sheet material 11 is installed in the movement path a to which the thin sheet material 10 moves.

Next, to explain the operation of the loading / unloading device for a sheet material of the present invention configured as described above.

As shown in FIG. 3, the first conveyer 110 and the second conveyer 120 are disposed to face each other, and form a movement path (a) through which the thin sheet material 10 is transferred to each other.

The thin plate material 10 is supplied from the first conveyer 110, and the thin plate material 10 is supplied along the movement path a.

Subsequently, the conveyed sheet material 10 is punched to a predetermined size by a processing apparatus 200 such as a press and processed.

The remaining thin plate material 10 ′ after the processing is transferred to the second conveyer 120 and discharged to the outside.

On the other hand, the processed sheet material 11 is continuously transported along the movement path (a), the loading / unloading device 300 of the present invention is a vacuum according to the size value of the processed sheet material 11 The processed thin plate material 11 can be moved to a predetermined position by the attraction force.

In detail, the photo sensor 400 positioned above the movement path a acquires an image of the processed thin sheet material 11 to obtain a size value of the processed thin sheet material 11. Then, the magnitude value is transmitted to the controller 380.

Here, the size value may be a width and length value of the processed thin sheet material 11, or may be an area value of the upper surface.

Subsequently, the controller 380 calculates a vacuum suction force corresponding to the received magnitude value and transmits an electrical signal to the vacuum providing unit 360.

Here, the control unit 380 is a vacuum suction force is set according to the size value of the thin plate material 11, the control unit 380 is a vacuum suction force corresponding to the size value of the thin plate material 11 is the predetermined vacuum suction force. You can choose from.

In addition, an adsorption end 373 in which a plurality of adsorption holes 373a are formed is detachably installed at the end of the adsorption rod 371.

Therefore, the suction end 373 may be artificially changed to correspond to the width of the thin plate material 11.

For example, as the number of adsorption holes 373a formed in the adsorption stage 373 increases, the width of the thin plate material 11 adsorbed on the adsorption stage 373 may increase.

Therefore, the adsorption end 373 may be selectively installed at one end of the adsorption rod 371 so as to correspond to the widths of the various thin plate materials 11.

The linear guide 374 is linearly moved to be positioned at the upper portion of the suction rod 371, and the suction end 373 is processed while the second body portion 320 is lowered by the lifting cylinder portion 340. It may be in close contact with the upper surface of the thin plate material (11).

Therefore, the processed thin sheet material 11 is adsorbed by the vacuum adsorption force formed in the adsorption holes 373a of the adsorption stage 373.

Subsequently, the loading / unloading unit 300 may be seated by moving the adsorbed processed sheet material 11 to a predetermined position.

In the above case, the loading / unloading device 300 of the present invention has been described to absorb and move one processed sheet material 11.

However, since the sheet material 10 continuously supplied along the movement path a is processed continuously by the processing apparatus 200, in this case, the loading / unloading apparatus 300 repeats the above process. It can be done with
