Description

Loading and unloading apparatus of plate for NCT}

The present invention relates to a device for loading and unloading the material of NCT (Numerical Control Turret punch press). In particular, by configuring loading and unloading to occur simultaneously within one device, work efficiency and space utilization are improved. It is structured to increase.

NCT (Numerical Control Turret Punch Press), which uses a wheel-type mold, is a processing machine that pressurizes and punches the plate by rotating the turret according to the order entered in the NCT when the plate as the raw material is loaded on the NCT surface.

To produce a product by punching with NCT, first load the plate into the NCT, and then unload and remove the plate after the punching work has been completed.

As the performance of NCT improves, the process of loading/unloading plates progresses very quickly. However, in the past, manually loading/unloading plates has the disadvantage of causing safety accidents.

In order to solve this problem, Republic of Korea Patent Publication No. 10-1631886 configures the adsorber to move back and forth between the point where the plate is loaded and the laser processing machine in order to position the loading/unloading of the plate. That is, the loading operation is carried out in the following order: the sheet on the top surface of the sheet loaded with the adsorber is adsorbed and fixed, the adsorber moves to the laser processor by the operation of the motor, and then the sheet adsorbed and fixed on the adsorber is placed on the conveyor of the laser processor.

Residues and manufactured products remaining after processing in the laser processing machine are discharged to the outside of the laser processing machine through a conveyor.

The conventional loading/unloading device configured in this way has the disadvantage of poor space utilization in the workplace because the loading and unloading operations are performed in separate locations.

In addition, if the laser processing machine is equipped with a conveyor, unloading is possible through the conveyor, but in the case of a processing machine without a conveyor, the remaining materials and manufactured products must be unloaded through a loading device.

As such, conventionally, loading and unloading are performed separately with one device, which has the disadvantage of poor workability.
