The present invention relates to a knitting needle needle needle device of the knitting machine in more detail based on a predetermined knitting plan input to the controller of the main body of the knitting machine, a lift for converting a plurality of knitting needles arranged on the needle of the knitting machine into a sliding motion A knitting needle pin needle device of a knitting machine capable of knitting a predetermined pattern by engaging or releasing between a cam and a rising cam butt of a knitting needle or a butt of a rising cam in contact with the lower tip of the knitting needle.

In jacquard knitting machines such as jacquard knitting machines, jacquard flat knitting machines, etc., the pattern procedure memory such as pin drums, tapes, floppy discs, etc. is used for the upper or lower movement of the knitting needles. Knitting needle drives have been used for transmitting stored patterning pross.

A jacquard circular knitting machine is usually composed of a knitting cylinder having a plurality of flat needles and a feeding device, and a flat needle drive device for transmitting a patterning procedure stored in a patterning procedure memory for vertical movement of the knitting needle. The knitting cylinder is rotated through the transmission mechanism by the motor. The rotation of the knitting cylinder, more precisely the rotation angle of the knitting cylinder, is detected by a decoder and transmitted to the panning procedure memory. The knitting procedure corresponding to the rotation angle of the knitting cylinder is passed from the patterning procedure memory to the knitting needle drive.

Many yarns are fed to knitting needles via a thread feeder. BACKGROUND OF THE INVENTION As a knitting needle driving device currently being widely used, there is a known pin needle driving device including a plurality of plates in which main portions are arranged so as to slide along each other.

The sliding motion of the plates in this device is based on signals emitted from pins on the pin drum or computer memory. When the plate moves toward the center of the knitting cylinder, it moves to the center of the knitting cylinder of the jack, which is in contact with the lower end of the knitting needle, so that the cambert installed in the lower part of the jack is released (removed) from the lifting cam.

Thus, by controlling the sliding motion of the plate by the signal emitted from the pin or the memory, the vertical motion of the corresponding knitting needle can be controlled and the fabric forming the predetermined pattern can be knitted.

At present high speed driving jacquard knitting is required, and in order to achieve such a high speed driving knitting, it is necessary to accelerate the reaction of the knitting needle driving apparatus.

However, there is a limit to the increase that can occur at the reaction speed or the sliding speed of the plate in the knitting needle drive device having a configuration in which a plate slides, such as a known knitting needle drive device.

It is usually possible to obtain high speed knitting machines by increasing the number of plates slid at the slide speed, but the knitting needle drive is too large due to the increased number of plates, making it difficult to install the knitting needle drive in a narrow space outside the knitting machine. do.

Therefore, a knitting needle driving apparatus having a plurality of fingers having a tip capable of rotating in Japanese Laid-Open Patent Publication No. 60-224845 has been proposed. This knitting needle driving device is useful because it has a fast reaction speed, and is compact and can reduce power consumption compared with the known knitting needle driving devices which are widely used at present.

However, in the knitting needle drive having the slide type finger and swing type finger as described above, the movement of the finger is negative when the pole of the electromagnet is positive (+). Or by applying a current to the pole of the electromagnet in such a way that it is reversed.

Therefore, the reaction speed of the knitting needle driven device operated by the electromagnet has the limit caused by the action of the electromagnet itself, and the optimum high speed of the electromagnet is about 80 cycles per second.

In addition, since the power consumption efficiency of the electromagnet is about 1% and the remaining current is consumed by heat, there is a problem in that the total consumption rate of the electric power is very high when the knitting needle drive device having the electromagnet is used.

As a result, although a needle needle drive with an electromagnet can be used for a sock knitting circle knitting machine having 240 needles and a rotation speed of 220 rpm, a pan-hose having 400 needles and a rotation speed of 400 to 1000 rpm can be used. It is impossible to provide this knitting needle driving apparatus in a circular knitting machine.

Therefore, in this situation, a conventional knitting needle driving apparatus has been used for panty-hose knitting by reducing the rotation speed of the circular knitting machine at a speed corresponding to the normal reaction speed of the conventional knitting needle driving apparatus.

Therefore, a knitting needle driving apparatus having a high speed response speed, small size, and low power consumption has been strongly demanded to enable the mounting of a high speed jacquard knitting machine.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a knitting needle tip device which adapts a needle tip to a needle tip to a high-speed reaction speed, and is small in size and precisely, and has a low power consumption rate. The purpose.

The above object is to project the outside of the stopper through a left and right stopper having an zigzag opening and an opening formed at the stopper with one end thereof supported by the housing. It is achieved by being composed of a plurality of fingers (assembly) alternately arranged in a zigzag at regular intervals along the sliding direction of the knitting needle.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 2 is a needle tip device of the present invention, and FIG. 3 is an exploded perspective view of the present invention, and a knitting needle needle needle device of a knitting machine comprising a stopper having an opening formed in a zigzag and a plurality of fingers alternately arranged with a predetermined gap in the opening. to be.
