이하 본 발명의 작용에 대해 설명하면 다음과 같다.Hereinafter will be described the operation of the present invention.

시트(150) 이송전에는 대차(111)는 주행레일(110)을 따라 후진되고, 승강부재(113)는 하강된 상태이다.Before the seat 150 is transferred, the trolley 111 is retracted along the running rail 110, and the elevating member 113 is lowered.

이와같은 대기상태에서 시트(150)를 이송작업을 수행하게 되면, 스위치(20) 조작에 따라 대차(111) 상에 설치되어 있는 구동모터(115)가 작동되어 와이어로프(116)로 연결되어 있는 승강부재(113)를 위로 끌어올리게 된다.When the sheet 150 is transferred in such a standby state, the driving motor 115 installed on the trolley 111 is operated by the switch 20 to be connected to the wire rope 116. The elevating member 113 is pulled up.

그리고 대차(111) 구동용 모터(117)가 작동되어 주행레일(110)을 따라 대차(111)를 시트(150)쪽으로 이동시키게 된다.The trolley 111 driving motor 117 is operated to move the trolley 111 toward the seat 150 along the running rail 110.

대차(111)가 주행레일(110)을 따라 시트(150)쪽으로 이동함에 따라 대차(111)의 승강부재(113)에 설치되어 있는 포크부재(114)는 콘베이어 위에 놓여진 시트(150) 상부로 이동하게 되고 대차(111) 구동용 모터의 정지작동에 따라 포크부재(114)는 정확하게 시트(150) 위에 위치하게 된다.As the trolley 111 moves along the running rail 110 toward the seat 150, the fork member 114 installed on the elevating member 113 of the trolley 111 moves to the upper portion of the seat 150 placed on the conveyor. In accordance with the stop operation of the motor for driving the trolley 111, the fork member 114 is accurately positioned on the seat 150.

포크부재(114)가 완전히 시트(150) 상부로 진입하게 되면 대차(111) 측면의 감지편(118)이 주행레일(110)의 전방감지센서(119)에 감지되면서 대차(111)는 현 위치에서 정지하게 된다.When the fork member 114 completely enters the upper seat 150, the sensing piece 118 on the side of the trolley 111 is detected by the front detection sensor 119 of the running rail 110, and the trolley 111 is in the current position. Will stop at.

그리고 상기 전방감지센서(119)의 감지신호에 따라 대차(111) 위에 설치되어 있는 구동모터(115)가 작동되어 스프로켓휠과 체인으로 연결되어 있는 회전축을 회전시키게 되고 회전축이 회전됨에 따라 와이어드럼으로부터 와이어로프(116)가 풀리면서 와이어로프(116)에 연결되어 있는 승강부재(113)를 하강시키게 된다.In addition, the drive motor 115 installed on the trolley 111 is operated according to the detection signal of the front sensor 119 to rotate the rotating shaft connected by the sprocket wheel and the chain and from the wire drum as the rotating shaft is rotated. As the wire rope 116 is released, the lifting member 113 connected to the wire rope 116 is lowered.

따라서 승강부재(113)에 설치되어 있는 포크부재(114)는 시트(150)를 향해 하강하게 되고 포크부재(114)에 설치되어 있는 흡착빨판(10)과 무게추(23) 또한 시트(150) 윗면으로 내려오게 된다.Therefore, the fork member 114 installed on the elevating member 113 is lowered toward the seat 150 and the suction sucker 10 and the weight 23 and the seat 150 installed on the fork member 114. It comes down to the top.

포크부재(114)가 어느정도 하강하게 되면, 시트(150)의 표면 굴곡정도에 따라 일측에 위치한 무게추(23)가 시트(150) 표면에 닿게 되고, 무게추(23)가 시트(150)에 의해 하강되지 못함에 따라 와이어(22)에 걸리는 무게추(23)의 자중이 해제되고 이에 따라 와이어(22)에 연결된 작동레버(21)가 위로 들려올려지면서 리미트스위치(20)를 온시키게 된다.When the fork member 114 is lowered to some extent, according to the degree of surface bending of the sheet 150, the weight 23 located on one side is in contact with the surface of the sheet 150, the weight 23 is placed on the sheet 150 As it is not lowered by the weight of the weight 23 is caught on the wire 22 is released, thereby operating lever 21 connected to the wire 22 is lifted up to turn on the limit switch 20.

이와같은 작용과정으로 포크부재(114)나 연장부재(50)에 설치된 전체 리미트스위치(20)의 신호가 온 상태가 되면, 이 신호에 따라 구동모터는 정지되어 승강부재(113)의 하강을 멈추게 된다.When the signal of the entire limit switch 20 installed in the fork member 114 or the extension member 50 is turned on by such an operation process, the driving motor is stopped according to this signal to stop the lowering of the elevating member 113. do.

이와 동시에 흡입펌프가 작동되어 흡입빨판(10)을 통해 공기를 흡입하게 되고, 흡입빨판(10)의 흡입작용에 의해 시트(150)는 흡입빨판(10)에 달라붙게 되는 것이다.At the same time, the suction pump is operated to suck air through the suction sucker 10, and the seat 150 is attached to the suction sucker 10 by the suction action of the suction sucker 10.

한편, 상기 흡입빨판(10)은 무게추(23)와 마찬가지로 포크부재(114) 하강에 따라 시트(150)를 향해 하강하게 되는 데, 일측 흡입빨판(10)이 먼저 시트(150)표면에 닿았다 하더라도 전체 리미트스위치(20)가 온될때까지 승강부재(113)는 하강을 계속 하게 되므로 흡입빨판(10) 또한 외측파이프(30)내로 내측파이프(31)가 삽입되어 승강부재(113)의 하강을 방해하지 않게 된다.On the other hand, the suction sucker 10 is lowered toward the seat 150 in accordance with the fork member 114 descends like the weight 23, one side suction sucker 10 first touched the surface of the seat 150 Even if the lift member 113 continues to descend until the entire limit switch 20 is turned on, the suction sucker 10 is also inserted into the outer pipe 30 so that the inner pipe 31 is lowered. Will not interfere.

또한, 흡착빨판(10)은 내측파이프(31)에 대해 자유롭게 굽어질 수 있게 되어 시트(150) 표면의 굴곡에 따라 각도를 달리하여 시트(150) 표면에 완전히 밀착될 수 있게 된다.In addition, the suction sucker 10 can be bent freely with respect to the inner pipe 31 so that the angle can be changed in accordance with the bending of the surface of the sheet 150 can be completely in contact with the surface of the sheet 150.

이 상태에서 상기와 같이 공기가 흡입되면 전체 흡입빨판(10)은 시트(150)표면에 완전히 부착된 상태가 되는 것이다.In this state, when the air is sucked as described above, the entire suction sucker 10 is completely attached to the surface of the seat 150.
