An air pipe (291) communicates with the lower side of the housing (260). Preferably, an intermediate wall 265 having a pinhole 266 formed therein is formed at a lower portion inside the housing 260. The air pipe 291 is formed in the space 294 between the intermediate wall 265 and the lower end of the housing 260.

[ So as to prevent the air flow to the air pipe 291 from being disturbed by the spring 279.

The perforation pin 270 includes a body 271 movably installed inside the housing 260. A ring groove is formed on the outer circumferential surface of the body 271, and an annular ring 273 for forming an airtight seal with the inner surface of the housing is provided in the ring groove. A groove-shaped actuator connection portion 274 is formed on the upper end of the body 271 of the perforation pin 270. A pin 278 is provided at the lower end of the body 271 of the perforated pin 270.

The perforated actuator extends through the upper hole 261 of the housing 260 and is engaged with the actuator connection portion 274 at the upper end of the body 271 of the perforated pin 270. In the illustrated embodiment, the perforated actuator 280 is illustrated as a hydraulic cylinder, but not limited thereto, various actuators may be used. The perforated actuator 280 is located inside the cylindrical case 283 and is supported by the cylindrical case 283.

The discriminating apparatus 200 further includes an infrared sensor 202 to sense the size and the size of the refrigerator by detecting the width and length of the refrigerator moving into the discriminating apparatus 200. However, according to the production status of the major producers of refrigerators, vacuum insulation is used only in a large-sized refrigerator of a certain size or more. Therefore, the size of the refrigerator is determined by the size of the infrared sensor, It is possible to distinguish refrigerators adopting non-vacuum insulation.

The judgment step S20 of discriminating between the refrigerator adopting the vacuum insulation material and the refrigerator adopting the non-vacuum insulation material made in the discrimination device 200 will be described as a whole.

When the refrigerator 10 is conveyed along the first conveyor 100 and is conveyed to the discriminating apparatus 200, the infrared sensor 202 senses this and the stopper 201 operates to stop the refrigerator 10 at the determined discrimination position .

Thereafter, the mobile frame 200 is operated to move the negative pressure detector 250 toward the wall of the refrigerator 10 so that the adsorption pad 285 of the negative pressure detector 250 moves to the refrigerator 10, So as to be brought into close contact with the wall.

At this time, the vacuum ejector 295 operates to suck air in the adsorption pad 285 to form a constant negative pressure, so that the adsorption pad 285 can be firmly adsorbed on the wall of the refrigerator 10.

Thereafter, the perforated actuator 280 is operated to advance the perforated pin 270 to puncture the wall of the refrigerator 10 to form a perforated hole, and then to be inserted at a predetermined depth and then retracted.

At this time, if the vacuum insulation material is present in the wall of the refrigerator 10, a hole is formed in the sheath material of the vacuum insulation material by the fin portion 278 of the perforation pin 270. Accordingly, the air in the closed space formed by the adsorption pad or the like is sucked into the vacuum insulating material through the perforation hole through the hole, so that the pressure sensor 290 senses the pressure reduction. That is, the pressure sensor 290 detects the negative pressure generated after the puncture, so that it is possible to determine whether or not the vacuum insulator exists in the wall of the refrigerator 10.

When the refrigerator 10 is discriminated as the vacuum insulator non-adopting refrigerator 10b in the discriminating step S20, the stopper 201 descends and the vacuum insulator non-adopted refrigerator 10b is conveyed along the first conveyor 100 as it is do.

If the refrigerator is judged to be the vacuum insulated material refrigerator 10a, the conveying step S30 is performed to transfer the vacuum insulated material refrigerator 10a to the second conveyor 150. [ That is, the refrigerator 10 transferred along the first conveying conveyor 100 is separated into the vacuum insulator-applied refrigerator 10a and the vacuum insulator non-inserting refrigerator 10b in the discriminating apparatus 200, and the transfer is separated.

The second conveyor 150 is formed to extend along the first conveyor 100 on the first conveyor 100. The second conveyor 150 may be installed on the side of the first conveyor 100, but may be formed on the first conveyor 100 in terms of minimizing installation space.

Then, the vacuum adsorber 340 The refrigerator 10a is placed on the second conveyor 150. [ Thereafter, the transfer unit 300 returns to the home position.

In the embodiment shown in the drawing, the conveying unit 300 is shown as a type in which the refrigerator 10a is clamped and transported by a vacuum suction method.

The air injector 410 is formed similarly to the negative pressure sensor 250 shown in FIGS. The air injector 410 having the same configuration as that of the pressure sensing unit 290 may be used. Air is injected into the perforation hole h punctured by the perforation pin 270 by supplying air through the air pipe 291.

When the vacuum insulator is provided in the wall of the refrigerator, the vacuum insulator is fixed to one side of the inner wall of the wall, and the space between the inner wall and the vacuum insulator is filled with urethane. When the air is injected, the urethane is separated from the inner wall and the vacuum insulating material can be easily removed.

As a subsequent step, an outer plate material cutting and separating step (S50) is performed in which the outer plate material of the wall in which the vacuum insulation material is accommodated is cut out and the outer plate material is separated from the outer plate plate material cutting and separating part 500.
