본 발명은 연속압출 성형과정의 이중벽 주름관체 절단시스템에 관한 것으로, 더욱 상세하게는 압출기에 의하여 연속 압출성형되는 이중벽 주름관체의 압출길이을 감지하고 일정 길이 이상 압출되었을 때 이를 삽지하여서 압출되는 이중벽 주름관체와 동일 속도로 이송하면서 신속하고 정밀하게 절단할 수 있도록 함을 목적으로 한 것이다.The present invention relates to a double wall corrugated pipe cutting system of a continuous extrusion molding process, and more particularly, a double wall corrugated pipe extruded by detecting an extrusion length of a double wall corrugated pipe continuously extruded by an extruder and inserting the same when extruded over a predetermined length. It aims to be able to cut quickly and precisely while feeding at the same speed as.
일반적으로, 주름이 비 나선형으로 형성된 이중벽 주름관체는 내관압출기와 외관압출기가 하나의 구조로 이루어지 압출기를 이용하여 내관 압출성형 후 그 외면에 연속하여 주름진 외관을 압출성형하는 것으로, 그 압출성형이 연속적으로 이루어지므로 압출성형된 관체를 운반 및 보관하기 위하여는 일정 길이로 절단하여야 한다.In general, the double-wall corrugated pipe formed in a non-helical form of the pleat is an extruder made of an inner tube extruder and an outer extruder having a single structure. Since it is continuous, the extruded tube should be cut to a certain length in order to transport and store it.
이에, 종래에는 연속하여 압출성형되는 이중벽 주름관체의 골 수를 통상의 리미트스위치로 카운트한 후 히팅선을 이용하여 절단하거나, 대형 톱날을 이용하여 절단하였다.Thus, in the related art, the bone marrow of the double-wall corrugated tube continuously extruded was counted using a conventional limit switch, and then cut using a heating line, or cut using a large saw blade.
그러나, 상기한 바와 같이 히팅선을 이용한 절단은 절단과정에 유독가스가 발생하여 작업환경을 저해하며, 대형 톱날의 경우에는 그 톱날의 크기가 관의 직경보다 두 배 이상 커야 하므로 많은 작업공간을 필요로 하며, 절단과정에 있어 톱날이 외부로 노출되게 되어 있어 작업상에도 용이하지 않은 문제점이 있었다.However, as described above, cutting using heating wires causes toxic gas to be generated during the cutting process, which hinders the working environment. In the cutting process, the saw blade is exposed to the outside, there was a problem not easy to work.
그 밖에도 다양한 절단 시스템이 제시되었으나 연속 압출성형되는 이중벽 주름관체의 절단에는 그 작업이 원활하지 못한 문제점이 있었다.In addition, various cutting systems have been proposed, but there is a problem in that the work is not smooth in the cutting of the double-wall corrugated tube continuously extruded.
이에, 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로, 연속 압출성형되는 이중벽 주름관체를 원활하고 용이하게 일정 길이로 자동 절단할 수 있도록 한 것으로, 이중벽 주름관체와 치합되는 감지기어에 의하여 압출성형되는 이중벽 주름관체의 압출길이를 감지하고, 압출성형되는 이중벽 주름관체를 집게형의 그리퍼로 삽지하며, 서로 대칭되게 구비되며 반원상의 궤적으로 회동되는 절단톱날에 의하여 이중벽 주름관체를 신속하고 정확하게 절단할 수 있도록 한 것이다.Accordingly, the present invention has been made to solve the above-mentioned problems, it is to enable the automatic cutting of the double wall corrugated pipe to be continuously extruded smoothly and easily to a predetermined length, the extrusion by the sensor gear meshed with the double wall corrugated pipe. Detects the extruded length of double wall corrugated pipe to be molded, inserts double wall corrugated pipe to be extruded with gripper of gripper type, and cuts double wall corrugated pipe quickly and accurately by cutting saw blades which are provided symmetrically with each other and rotated in a semicircular trajectory It is to be done.
