socks knitting machine

The present invention is to provide a sock knitting apparatus that enables knitting in the form of knit, miss, and tuck in the forward and reverse directions by providing a single cam which enables all the functions of miss, knit, and tuck when three-dimensional pattern knitting is performed. Provided is a sock knitting apparatus comprising: needles and needle jacks inserted into a plurality of insertion slits formed on the outer circumferential surface of a cylinder coupled vertically to the upper part of a base plate and coupled to slide up and down; a plurality of main cams mounted on the base plate so as to be operated upward and downward while the lower ends of the needle jacks are supported; and auxiliary cams connected between the main cams, wherein the main cam includes: an arc-shaped base; and a cam plate formed upright on the upper surface of the base to have an arc-shaped curvature. The cam plate includes: a first curved portion protruding to be stepped with the base and formed in an arc shape; a first inclined surface connected to the first curved portion and formed to be inclined upward; a first concave portion connected to the upper part of the first inclined surface while being formed concave; a top portion connected to the first concave portion and formed to be upwardly convex; a second concave portion connected to the top portion and formed symmetrically with the first concave portion; a second inclined surface connected to the second concave portion, formed downwardly inclined, and formed symmetrically with the first inclined surface; and a second curved portion formed connected to the end of the second inclined surface. A guide cam groove with both side inclined portions and an upper horizontal portion functions as a step by being formed concave on the inner surface of the cam plate so as to match with the first inclined surface, the first concave portion, the top portion, the second concave portion, and the second inclined surface of the cam plate. 본 발명은 3D 입체 패턴 편직시 Miss, Knit, Tuck 기능이 모두 가능한 단일의 캠(CAM)을 제공함으로써 정방향, 역방향시 knit, miss, tuck 형태의 편직이 가능하도록 하는 양말 편직장치를 제공하기 위한 것으로서, 베이스플레이트의 상부에 수직방향으로 결합되는 실린더의 외주면에 형성된 다수의 삽입슬릿에 삽입되어 상하로 슬라이딩되도록 결합되는 바늘과 니들잭을 포함하고, 상기 니들잭의 하단이 지지되면서 승강작동되도록 베이스플레이트에 장착되는 복수개의 메인 캠과, 각 메인 캠들 사이에 연결되는 보조 캠들을 포함하고, 상기 메인 캠은 호형으로 된 기대와, 기대의 상면에 직립되게 형성되되 호형의 곡률을 갖도록 하는 캠판을 포함하는 양말 편직 장치에 있어서, 상기 캠판은 상기 기대와 단턱지게 돌출 형성되며 호형으로 된 제1만곡부와, 상기 제1만곡부에 이어져 상방 경사지게 형성되는 제1사면과, 상기 제1사면의 상부에 이어지되 오목하게 형성되는 제1요부와, 상기 제1요부
