The finger 20 has an upper protrusion 21 protruded upward at one end thereof and a lower protrusion 22 protruding downwardly at the other end thereof. The other end of the finger 20 has two branched portions 24 And 25 are formed on the upper surface of the base 25. The branch portions 24 and 25 are guided in the forward and backward movement by the guide pin 42 disposed therebetween, And acts as a rotary shaft when rotating.

Holes are formed in the free ends of the branching portions 24 and 25 so that the chromaticity is penetrated and the chromaticity is supplied by the forward and backward movement of the finger 20. An intermediate protrusion 27 is formed on the lower side of the intermediate portion of the finger 20 to be in contact with the horizontally bent free end of the spring member 60, The free end also resiliently supports the middle portion of the finger and provides an elastic force so that it can be retracted relative to the downwardly pivoted finger.

The protruding protrusion 26 protrudes upward from the upper surface adjacent to the branching point of the branching portion 24 so that the finger push lever 30 is pressed against the pushing projection 18 of the pivoting lever 16 The protruding protrusion 26 of the finger comes into contact with the bottom surface of the finger push lever 30 so that the finger 20 moves downward about the guide pin 42 in the clockwise direction In the direction of rotation. At this time, the upper protrusion 21 formed at one end of the finger 20 is lowered and the lower protrusion 22 protruded.

The cutting blade 50 is rotatably mounted clockwise on the spring fixing pin 44. The cutting blade 50 is formed with a downwardly curved arc-shaped slot 46, A guide pin 51 provided between the side covers 2 passes through the slot 46 so as to penetrate the side cover 2. The cutting blade 50 is supported by the slit 46 in which the guide pin 51 is inserted as the finger 20 is pushed by the intermediate protrusion 27 formed to protrude in the middle lower side of the finger when the finger 20 moves to the right in the drawing, So that the cutting blade rotates in the clockwise direction in accordance with the shape bent downward.

The operation of the stripper for a circular knitting machine of the present invention will be described with reference to FIGS.

The pushing pins 12-1, 12-2, 12-3, and 12-4 are pressed by the actuators not shown in the drawing according to the program previously programmed to push the pivoting lever as shown in Fig. 2, The right side of the rotation shaft of the rotation lever 16 is pushed in the clockwise direction when the rotation lever is rotated in the clockwise direction and the release pins 13-1, 13-2, 13 3, and 13-4 protrude upward, and when the release pins are depressed, the push pins rise as opposed to the above.

In this state, the cam member 70 is pushed to the right in the figure in contact with the lower protrusion 22 so that the finger 20 advances to the right as shown in FIG. 5, When you retreat, you are pulled to supply the color. The movement of the finger 20 is stopped by the contact of the upper protrusion 21 of the one end of the finger with the stopper pin 41. The movement of the finger of the finger is transmitted to the branching portions 24 and 25 formed on the other side of the finger, And guided linearly by the guide pin 42 provided between them to move smoothly without noise,

As the finger 20 moves to the position of FIG. 5 to the position of FIG. 5, the intermediate protrusion 27 formed at the lower side of the finger pushes the cutting edge 50 as shown in FIG. 5, The cutting blade rotates clockwise along the downwardly curved slot 46.

Then, when the release pins 13-1, 13-2, 13-3, and 13-4 protruded by the actuator are pressed, the pushing projections 18 of the pivoting lever 16 move from the position of FIG. The push pins 12-1, 12-2, 12-3, and 12-4 are moved to a position where they are in contact with the upper surface of the finger push lever 30 of the finger push lever 30, The upper protrusion 21 at one end of the upper plate 20 is raised at the position of Fig. At this time, the upper protrusion 21 of the finger 20 raised by the cam member 80 is moved to the initial position to the position of FIG. At this time, the cutting blade 50 is rotated in the counterclockwise direction at the position shown in FIG. 5, and cuts off the color patches supplied by the branching section 25 and is supplied to the knitting needle not shown in the figure.

As described above, the stripper for a circular knitting machine according to the present invention is formed such that the other end of the finger 20 is separated from the two branch portions 24 and 25, and a guide pin 42 is provided therebetween, So that the cutting operation of the cutting blade 50 is smoothly performed. Thus, it is suitable for a high-speed circular knitting machine, the feeding of coloring of the finger can be performed smoothly and quickly, and the productivity of knitting is improved. There is no place where the guide pin 42 is hooked, so that the noise is greatly reduced, and the structure is simplified, so that the manufacturing cost is reduced and the operation reliability is improved.
