본 고안은 물탱크나 정화조 등 대형 합성수지제 통체의 하단부에 별도로 성형된 밑판을 접합하는 합성수지 탱크의 밑판 부착장치에 관한 것이다.The present invention relates to a bottom plate attaching device of a synthetic resin tank for bonding the bottom plate formed separately to the lower end of a large synthetic resin cylinder such as a water tank or a septic tank.

종래 용량이 적은 용기 등은 밑판이 형성된 단일의 통체로 사출하거나 압형하여 성형할 수 있으나 용량이 큰 물탱크나 정화조와 같은 대형의 합성수지 통체의 경우에는 현재의 국내 사출기 등으로는 사출 용량의 미달로 인하여 밑판과 통체의 단일체로 성형하지 못하고 대부분 통체와 개체별로 구분 성형한 다음 통체에 밑판을 접합하고 있는 실정이다.Conventionally, a container with a small capacity can be injected or pressed into a single cylinder having a bottom plate, but in the case of a large synthetic resin cylinder such as a large water tank or a septic tank, the current domestic injection machine or the like may not meet the injection capacity. Due to this, it is impossible to form a single body of the base plate and the cylinder, and most of them are molded by the body and the individual, and then the base plate is joined to the cylinder.

이때 통체에 밑판을 접합하는데 특별히 구성된 부착장치가 없이 접합할 통체를 세워 접합할 밑판을 통체의 상단부에 맞추어 올린 다음 여러개의 클램프를 접합 플랜지 끼리 미리 협지시킨 다음 용접기로 접합하였으나 속이 빈 통체가 원통형을 유지할 수 있게 통체 내부에 속심을 끼워 두어야 하고 여러개의 클램프를 일일히 집합 플랜지에 협지해야 하기 때문에 작업이 번거럽고 불편하여 능률적으로 통체에 밑판을 접합 생산하기 어렵고 용접부의 접합 강도가 균일하지 못하여 누수의 우려가 있는 등 고품질을 기대하기 어려운 문제점이 있었다.At this time, the base plate to be joined is raised without the specially designed attachment device for joining the bottom plate to the cylinder, and the bottom plate to be joined is raised to the upper end of the cylinder, and then several clamps are sandwiched in advance with the joining flanges, and then welded with a welder. Since it is necessary to insert a core inside the cylinder to be maintained and clamp several clamps to the assembly flange, the work is cumbersome and inconvenient, and it is difficult to efficiently produce the base plate to the cylinder, and the joint strength of the weld is not uniform. There is a problem that it is difficult to expect high quality, such as there is a concern.

또한 종래 통채가 아닌 관이 접합기(일본 공개 실용신안공보 공고번호 제53-64166호)가 알려져 있으나 이는 대판상에 여러개의 관체결구가 방사상으로 배치 형성된 환상의 고정 클램프와 가동 클램프를 설치하여 접합할 관체를 체결구에 의하여 협지한 다음 가열기에 의하여 관단부를 가열하면서 관체를 측방으로 가압하여 열 접합하게 된 것으로 관체결구를 조작하여 관체의 굵기에 따라 임의로 조절할 수 있게 되어 있을 뿐 원통형의 대형통체와 납작한 밑판 등을 협지하는 데는 적당하지 못하여 통체와 밑판의 접합에는 사용할 수 없는 것이어서 지금까지 여전하게 수공으로 통체에 밑판을 접합하고 있다.In addition, a conventional non-tubular pipe jointer (Japanese Laid-Open Utility Model Publication No. 53-64166) is known, but it is joined by installing an annular fixed clamp and a movable clamp formed by radially arranging several pipe fasteners on a large plate. The pipe is clamped by the fastener, and then the tube is heated by pressing the pipe to the side while the heater is heated. The pipe fastener can be manipulated arbitrarily according to the thickness of the pipe. It is not suitable for sandwiching the cylinder and the flat bottom plate, so it cannot be used for joining the cylinder and the bottom plate. Thus, the bottom plate is still joined to the cylinder by hand.

본 고안은 이러한 종래의 문제점을 시정하기 위하여 밑판을 접합할 대형의 합성수지제 통체의 원주면을 협지하기에 적당한 크기의 반호상으로 만곡된 수개의 상하 협지편을 나란히 형성한 상부 협지틀과 하부 협지틀을 구성하여 기판의 일측 바닥에 하부 협지틀이 고정되게 설치하고 상부 협지틀의 상부에 공지한 유압실린더 기구를 설치하여 유압에 의하여 상부 협지틀을 개폐하여 통체를 협지할 수 있게 하며 기판 타측에는 환상의 밑판 협지틀이 형성된 이동대를 유압실린더 기구와 함께 설치한 구성으로 하여 통체의 협지틀과 밑판의 협지틀에 각각 접합할 합성수지제 통체와 밑판을 각각 협지시킨 다음 전기 히터에 의하여 플랜지의 접합면을 가열 용해시킨 즉시 이동대에 의하여 밑판을 통체의 단부에 가압 밀착시키어 접합 플랜지끼리 견고하게 접합되게 함으로서 종래 수공으로 통체에 밑판을 접합할 때의 통체내부에 속심을 끼워 넣어야 하는 폐단과 접합 플랜지에 여러개의 클램프를 협지해야 하는 번거럽고 불편한 문제점을 시정하고 일정한 고품질로 통체에 밑판을 보다 능률적으로 접합 생산할 수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.In order to correct this problem, the present invention has an upper and lower pincers formed side by side with a plurality of upper and lower pincers, which are curved side by side in an arc shape suitable for clamping the circumferential surface of a large plastic barrel to which the base plate is to be joined. The frame is formed so that the lower clamping frame is fixed to the bottom of one side of the board, and a well-known hydraulic cylinder mechanism is installed on the upper clamping frame to open and close the upper clamping frame by hydraulic pressure so as to clamp the cylinder. The movable base on which the annular bottom plate clamping frame is formed is installed together with the hydraulic cylinder mechanism. The cylindrical body and the bottom plate to be joined to the clamping frame and the clamping frame of the bottom plate are sandwiched, respectively, and then the flanges are joined by an electric heater. Immediately after dissolving the surface by heating, the base plate is pressed against the end of the cylinder by a moving table, Fixing the troublesome and inconvenient problem of clamping several clamps on the closed end and the joining flange when the bottom plate is to be inserted into the cylinder by hand by correcting the conventional method and fixing the bottom plate on the cylinder with consistent high quality As described in detail by drawing to be able to produce a joint as follows.

A cylinder D is inserted into the lower clamping frame 2 so as to be in close contact with the upper and lower clamping pieces 2a and 2b, and the upper clamping frame 2 'is combined with the lower clamping frame 2 to fasten the fastening screw 4 to the fastening plate. The flange (F ') of the base plate (B) to be joined is clamped to the clamping frame (6) formed on the movable table (7') so as to face the flange (F) of the cylinder, and then the hydraulic cylinder (9). By simultaneously inserting the electric heater 11 which moves the movable base 7 by the operation of between the joining flanges F and F ', as shown in FIG. 4 and FIG. 5 (a), the flange F (F ') contacts and heats the electric heater 11, and when the joint surface of the flange melts, the moving base 7 is slightly retracted, and the electric heater 11 is temporarily moved upward, and then the fifth ( b) immediately as indicated in the diagram The movable base 7 is moved to the cylindrical body, and the joined surfaces of the flange F of the cylinder D and the flange F 'of the base plate B are pressed and bonded to each other, and after the cooling time has elapsed, the movable table 7 The upper clamping frame 2 'by the operation of the hydraulic cylinder 5, and remove the cylinder to which the bottom plate is joined, and then work it again in the same manner as the first time. An upper plate frame and a lower plate frame formed side by side in an annular manner are installed on one side of the substrate, and the base plate is formed on one side of the substrate together with a known hydraulic cylinder mechanism. Since the cylindrical body and the bottom plate can be easily clamped to the pincer frame, the cylindrical frame is maintained by the pinch frame without inserting the inner core for the cylindrical body. It can be securely clamped, and the joint flanges of the cylinder and the bottom plate can be heated and dissolved at the same time by an electric heater, so that the bottom plate can be firmly joined by pressing the bottom plate to the cylinder at once, and when the bottom plate is pressed to the cylinder, the flange of the cylinder clamps the clamping frame. It can increase the joint strength of the base plate and the cylinder without being pushed from side to side, or flowed to the side. This solves the problems of conventional manual work, and can produce the base plate more efficiently with large quality plastic cylinders. It works.
