In addition, the present invention is characterized in that feeders (13, 14) for precisely feeding and feeding the material punched at the rear of the press with a cutter are provided, and a pair of flat belt main shaft (12) And a belt (15).

A pair of the flat belt main shaft 12 and the auxiliary shaft 09 are horizontally installed so as to be rotatable at intervals below the feeders 13 and 14. [

The flat belt 15 is wound to form a multi-row closed loop at intervals so as to connect the pair of flat belt main shaft 12 and the auxiliary shaft 09 to each other and is conveyed from the feeders 13, And then moves back along the material.

Therefore, it is preferable that the flat belts (15) of a plurality of rows are made of a material having a surface that is not too smooth and has a certain degree of frictional force so as to move along the material.

At this time, it is preferable that a plurality of engagement grooves are formed at intervals on the outer circumferential surfaces of the pair of flat belt main shaft 12 and the auxiliary shaft 09 in order to prevent the flat belt 15 from being separated.

Here, the lower power transmission guide roll 01 and the upper auxiliary transmission guide roll 01, which rotate in opposite directions with the power transmission belts 07 in multiple rows interposed therebetween to move the power transmission belt 07 backward, (02).

The auxiliary shafts 09 are installed in pairs so as to be rotatable at intervals and wound to be closed by a moving belt 08 so as to be connected to each other. And the power is transmitted.

It is preferable that a plurality of timing pulleys 03 on which the moving belt 08 is wound are installed at intervals on the pair of auxiliary shafts 09.

Further, it is preferable that an auxiliary transmission guide roll cylinder 05 for moving the auxiliary transmission guide roll 02 downward to approach the power transmission guide roll 01 when the power transmission belt 07 is moved .

In the meantime, the present invention can include a belt stretching means for stretching and contracting the distance between the auxiliary shafts 09 (i.e., the distance between the feeder and the cutter). The belt stretching means includes a guide roll moving plate, a guide roll moving plate LM guide 10 And a plurality of pairs of guide bearings 04 and an auxiliary guide roll 06.

The guide roll moving plate is a plate that is moved by the guide roll moving plate LM guide 10 and is provided with the power transmission guide roll 01, the auxiliary transmission guide roll 02 and the auxiliary shaft 09 on the rear side.

The guide roll moving plate LM guide 10 guides the back and forth movement of the guide roll moving plate by manual operation by an operator.

It goes without saying that the flat belt main shaft 12 and the auxiliary shaft 09 may be configured to rotate along the material in a non-powered state in order to reduce power consumption and prevent malfunction.

The punching apparatus having the above-configured stretchable multi-layer belt conveying apparatus of the present invention operates as follows.

In order to solve the problem that when the material is fed or sagged, the metal mold is not accurately and accurately sized during the metal stamping process and the material is not cut smoothly and neatly during the material cutting process after the transfer, The auxiliary transfer guide roll cylinder 05 is operated to transfer the material.

When the auxiliary transfer guide roll cylinder 05 is moved downward by the air, the auxiliary transfer guide roll 02 is also moved downward. When the auxiliary transfer guide roll cylinder 02 is brought into contact with the power transmission guide roll 01, Is rotated by the motor and rotated in a direction different from that of the auxiliary transfer guide roll 02 which is engaged.

Therefore, the material is interposed between the power transmission guide roll 01 and the auxiliary transmission guide roll 02 and continues to move in the red arrow direction in the drawing.

Next, the power transmission belt 07 interposed between the power transmission guide roll 01 and the auxiliary transmission guide roll 02 is also engaged and moved. When the power transmission belt 07 is moved, the timing pulley 03) and the shaft in the same direction.
