본 발명은 후판을 적치하는 장치에 관한것으로 보다 상세히는 후판공장의 로울러테이블위에 후판을 적치하여 이송작업이 보다 용이하도록된 후판자동적치장치에 관한것이다.The present invention relates to a device for stacking a thick plate, and more particularly, to a thick plate automatic stacking device that is easy to transport by stacking the thick plate on the roller table of the thick plate factory.

일반적으로 후판공장에서는 생산되는 강판의 두께가 두껍고 길이와 폭이큰 중량물이기때문에, 후판을 제품창고로 이송하기 위해서는 자석기중기(magnetic crane)를 이용하여 로울러테이블에서 후판을 1매씩 로울러테이블 측면의 빈공간에 쌓은후 천정크레인을 이용하여 제품창고로 운반하는 것이다.In general, in the thick plate factory, the steel plate produced is thick, long and wide, so that the heavy plate can be transported to the warehouse by using a magnetic crane. After stacking in space, it is transported to the product warehouse using ceiling crane.

그러나, 자석기중기로서 후판을 차례로 로울러테이블 측면에 적치하는 과정에서, 생산되는 후판의 수량이 많기때문에 장시간이 소요되며, 특히, 자석기중기의 과도한 사용으로인하여 후판생산 원가의 상승을 초래하고, 생산성이 저하되는 것이었다. 또한 후판이 중량물이기때문에 적치과정에서 작업자의 안전사고와 후판 낙하에따른 설비사고도 초래할 수 있는 문제점을 갖추고 있었다.However, in the process of placing the thick plates on the side of the roller table as a magnetic crane in turn, it takes a long time because the number of heavy plates produced is large, in particular, the heavy use of the magnetic crane causes an increase in the production cost of the heavy plates, It was to be degraded. In addition, since the heavy plate is a heavy product, there was a problem that can cause a safety accident of the worker and equipment accidents due to the fall of the heavy plate in the process of loading.

미설명부호(200)는 리미트스위치(LIMITSWITCH)(300)는 감속모터 작도용 전원스위치(A)는 후판이다.Reference numeral 200 is a limit switch (LIMITSWITCH) 300 is a power switch (A) for the reduction motor construction is a thick plate.

이하, 본 발명의 작용 및 효과에 대하여 설명한다.Hereinafter, the operation and effects of the present invention will be described.

먼저, 이송되는 후판(A)의 폭에 따라 감속모터(48)를 이용하여 이동적치대(46)를 적절하게 위치조정하고, 유압실린더(30)를 작동시켜 구동부(20)의 작동레버(22)를 피스톤로드(31)로서 밀어주게되면, 상기 작동레버(22)와 회전가능토록 결합된 연겨레버(16)가 축(10)(10')을 중심으로 반시계방향으로 50°정도 회전한다. 이때, 각각의 연결부재(16)는 축(10)(10')과 일체로 결합되어 있기때문에 상기 축(10)(10')을 반시계방향으로 50°회전시키고, 상기 축(10)(10')의 회전에 따라 작동부(40)를 연결하는 연결 프레임(18)도 반시계 방향으로 50°회전하게 되며, 상기 연결프레임(18)의 로울러(19)가 안내대(58)내에서 좌측으로 회전이동되면서 안내부재(42c)에 의하여 적치대(40a)가 상승한다.First, according to the width of the rear plate (A) to be transported by using the reduction motor 48 to properly position the moving platform 46, and operating the hydraulic cylinder 30 to operate the operating lever 22 of the drive unit 20 ) Is pushed as the piston rod 31, the connecting lever 16 rotatably coupled with the actuating lever 22 rotates about 50 ° counterclockwise about the shaft 10, 10 '. do. At this time, since each of the connecting members 16 are integrally coupled with the shafts 10 and 10 ', the shafts 10 and 10' are rotated by 50 ° counterclockwise, and the shaft 10 ( 10 '), the connecting frame 18 for connecting the operation unit 40 is also rotated by 50 ° counterclockwise, the roller 19 of the connecting frame 18 in the guide 58 The stockpile 40a is raised by the guide member 42c while moving to the left.

이러한 상태에서 로울러테이블(100)의 이송로울러(120)를 회전시켜 후판(A)를 진입시키면 고정적치대(44)의 돌조(56)와 이동적치대(46)의 돌조(56') 사이에 후판(A)의 양측 모서리가 인접하도록 진입되고, 후판(A)이 로울러테이블(100)의 일측선단에 부착된 리미트스위치(200)와 접촉하면, 유압실린더(30)가 피스톤로드(31)를 후퇴시키고, 전전시키는 1싸이클(Cycle) 동작을 수행하게 된다. 피스톤로드(31)가 후퇴하게되면 작동레버(22)와 결합된 연결부재(16)가 축(10)(10')을 중심으로 시계방향으로 50°회전하게 되고, 상기 연결부재(16)와 일체로 결합된 축(10)(10') 및 연결프레임(18)도 시계방향으로 50°회전하며, 따라서, 적치대(40a)는 하향이동되어 원래의 위치로 복귀하게 된다. 이때, 이동적치대(46)의 돌조(56')와 고정적치대(44)의 돌조(56)에 형성된 경사면(56a)(56a')에 후판(A)의 양측모서리가 접촉하면서 적치대(40a)가 하향이동되고, 후판(A)의 모서리에 의하여 돌조(56)(56')가 이동적치대(46) 및 고정적치대(44) 내부로 삽입되며 상기 판스프링(52)(52')는 각각 수축하게된다. 다음, 상기 돌조(56)(56')가 후판(A)보다 하부로 내려가게 되면 판스프링(52)(52')의 탄력작용으로 돌조(56)(56')가 돌출하게 되고 돌조(56)(56')의 상부면이 후판(A)의 양측모서리 하부면과 접촉하게된다.In this state, when the feed roller 120 of the roller table 100 is rotated to enter the rear plate A, the thick plate is formed between the protrusion 56 of the fixed base 44 and the protrusion 56 'of the movable base 46. When both edges of (A) enter adjacent to each other and the rear plate (A) comes into contact with the limit switch 200 attached to one end of the roller table 100, the hydraulic cylinder 30 retracts the piston rod 31. One cycle (Cycle) operation is performed. When the piston rod 31 is retracted, the connecting member 16 coupled with the actuating lever 22 rotates 50 ° clockwise about the shafts 10 and 10 ', and the connecting member 16 The integrally coupled shafts 10, 10 'and the connecting frame 18 also rotate 50 [deg.] In the clockwise direction, so that the loading stand 40a is moved downward to return to its original position. At this time, both side edges of the rear plate A are in contact with the inclined surfaces 56a and 56a 'formed on the protrusion 56' of the movable holder 46 and the protrusion 56 of the fixed holder 44. ) Is moved downwards, and the protrusions 56 and 56 'are inserted into the moving base 46 and the fixed base 44 by the edges of the rear plate A, and the leaf springs 52 and 52' Each will contract. Next, when the protrusions 56 and 56 'are lowered below the rear plate A, the protrusions 56 and 56' protrude by the elastic action of the leaf springs 52 and 52 'and the protrusions 56 The upper surface of the 56) is in contact with the lower surface of both edges of the rear plate (A).

그리고, 피스톤 로드(31)가 전진하게됨에 따라 다시 작동레버(22)가 연결부재(16)를 50°반시계방향으로 회전시키고 적치대(40a)를 상승시키면, 후판(A)이 돌조(56)(56')의 상부에 위치되어 적치대(40a)와 함께 로울러테이블(100)로부터 상승되고, 상기돌조(56)(56') 사이로 다음 후판(B)이 진입하게된다. 새로진입한 후판(B)이 다시 로울러테이블(100)의 리미트스위치(200)를 접촉하게되면 적치대(40a)는 시계방향으로 하향되면서 돌조(56)(56')위의 후판을 새로 진입한 후판(B)위에 얹어놓고, 로울러테이블(100) 하부로 이동되며, 피스톤로드(31)의 전진에 따라 적치대(40a)가 상승되면 이중으로 포개진 후판(A) (B)은 돌조(56)(56')의 상부면(56b)(56b')에 의해 적치대(40a)와 함께 상승되어 로울러테이블(100)로부터 분리되게 된다. 상기와같은 작용을 반복하게 되면 적치대(40a)의 돌조(56)(56')위에 다수매의 후판이 쌓이게되고, 원하는 매수만큼 적치가 완료되면 천정크레인으로 걸고리와 체인을 이용하여 제품 창고로 이송하면된다.Then, as the piston rod 31 moves forward, when the operation lever 22 rotates the connecting member 16 in a 50 ° counterclockwise direction and raises the loading base 40a, the rear plate A is provided with a protrusion 56. Located at the top of the 56 ', it is raised from the roller table 100 together with the loading table 40a, and the next thick plate B enters between the protrusions 56 and 56'. When the newly entered rear plate B comes into contact with the limit switch 200 of the roller table 100 again, the stock holder 40a moves downward clockwise and newly enters the rear plate above the protruding portions 56 and 56 '. Placed on the rear plate (B), is moved to the lower roller table 100, the double plate (A) (B) is overlapped when the pile up (40a) is raised as the piston rod 31 is advanced. The upper surfaces 56b and 56b 'of the upper surface 56' are raised together with the loading base 40a to be separated from the roller table 100. When the above operation is repeated, a plurality of thick plates are stacked on the protrusions 56 and 56 'of the loading stand 40a, and when the stacking is completed as many as desired, the hooks and chains are used as hooks and chains to the product warehouse. Just transfer

상기와 같이 본 발명에 의하면 후판을 적치하기 위하여 자석기중기를 사용하지 않기때문에 원가절감의 효과가 얻어지고, 단시간내에 많은양의 후판을 적치할 수 있기때문에 후판의 적치시간 단축으로 인하여 생산성이 향상되는 효과를 얻게된다.As described above, according to the present invention, since the magnetic crane is not used to stack the thick plate, the cost reduction effect can be obtained, and a large amount of the thick plate can be stacked within a short time, thereby improving productivity by shortening the stacking time of the thick plate. You get the effect.
