BACKGROUND OF THE INVENTION [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a knitting needle unit used in an upper weaving machine.

6 shows a conventional knitting needle unit, which includes a knitting needle body 72 having a hook 71 and a latch 71 for opening and closing the hook 70, a knitting needle 72 attached to the bottom of the knitting needle body 72, And a presser 74 provided with a butt 76 projecting in the same direction as the butt 75 against a side of the jack 73 and the jack 73 provided with the jack 75. This knitting needle unit is inserted into each of a plurality of parallel knitting needles D2 formed in the knitting needle bed B2.

The carriage C2 is provided to move along the monotonous bed B2 in the direction in which the single-sided D2 is arranged. Has a reference surface 81 with two types of cams 82 and 83 that are suitable for facing the needle bed B2 and engaging the butt 75. The cams 82 and 83 have different protrusion degrees and shapes of the guide surfaces. That is, the cam 83 protrudes more remarkably from the reference surface 81 than the cam 82. The carriage C2 is provided with a solenoid 84 suitable for pressing the butt 76.

As shown in FIG. 6, when the carriage C2 moves in the direction of the knitting needle bed D2 in which the butt 76 not pressed by the solenoid 84 is arranged, The butt 75 is guided by the cam 82 so that the knitted fabric main body 72 moves up and down together with the jack 73. [

7, when the carriage C2 is moved by the solenoid 84 toward the one-step pushed butt 76, the cam 83 guides the butt 75 and the needle 73, together with the jack 73, (72) up and down. Due to the different shapes of the cams 82 and 83, the knitting needle body 72 moves up and down to different degrees at different timings in the state shown in Fig. 7 than in the state shown in Fig.

The butt 75 does not engage with any of the cams 82 and 83 when the butt 76 is pushed further by the solenoid 84 until it completely retracts into the single entry groove D2, not moving.

As the degree of projection of the butt 76 in the single entry slot D2 varies with the solenoid 84, the movement of the needle unit can be controlled and thus any desired tissue pattern can be formed.

One problem with such a conventional knitting needle unit is that the knitting needle body 72 is moved up and down by the presser 74 pressing the jack 73 so that the frictional resistance between the presser 74 and the jack 73 And it takes a lot of energy to move the carriage C2.

It is an object of the present invention to provide a knitting needle unit with no friction loss when the movement is changeable and the knitting needle body moves up and down.

Other features and objects of the present invention will become apparent from the following description made with reference to the accompanying drawings.

[Detailed Description of Preferred Embodiments]

Embodiments of the present invention are described with reference to the accompanying drawings.

Referring to FIG. 1, a knitting unit according to the present invention includes a select jack 1 inserted into a plurality of parallel knitting needles D1 formed in a knitting needle bed B1 and arranged in order from bottom to top, (2) and a knitting needle body (3).

The select jack 1 has a lower, middle and upper butts 4, 5 and 6 on one side.

The butts 5 of the select jack 1 in the adjacent slit groove D1 are arranged in the longitudinal direction with respect to each other.

On one side of the push-up jack 2, a butt 7 and a protrusion 8 are provided near its bottom end and in the middle region thereof, respectively.

The knitting needle body 3 has a branched bottom area made up of the supporting piece 9 and the elastic piece 10. [

The push-up jack 2 has its top end slidably inserted between the support piece 9 and the resilient piece 10. The resilient piece 10 is tilted towards the push-up jack 2 and recesses 11 and 12 are formed on the inner surface near its bottom end. When the push-up jack 2 moves up and down, the protrusion 8 engages with the recesses 11 and 12.

The knitting needle body 3 has a butt 13 on the outer surface of the elastic piece 10 near the bottom end and a butt 14 provided on the base of the elastic piece 10 and projecting in the same direction as the butt 13 .

The recess 11 is deeper than the recess 12 so that when the protrusion 8 of the push-up jack 2 is received in the recess 11, the butt 13 protrudes one step from the single-entry slot D1 , So that when the projection 8 is in the recess 12, the butt 13 protrudes from the partial seating groove D2 in two steps. When the projection 8 is not received in any of the recesses 11 and 12, the butt 13 is fully retracted into the single-sided groove D1. The knitting needle body 3 has a latch 16 for opening and closing the hook 15 and the hook 15 at the top end thereof.

The carriage C1 is provided to move along the monotonous bed B1 in the direction in which the single-feeding slot D1 is arranged. And has a reference surface 21 with cams 22-38 as shown in FIG. 2, facing the mononergic bed B1. The cams 24, 28, 35 and 38 are protrudable from the reference surface 21. The degree of protrusion of the cams 31 and 32 at the reference surface 21 is changeable.

The cam 34 is movable along the guide groove 39 formed on the reference surface 21. A solenoid 40 is provided in the area between the cams 22 and 25 to press each butt 5.

In the second figure, the solid line, the dashed line and the dashed line indicate that the carriage C1 protrudes to the lower surface of the left cam 24, the right cam 28 and the cam 38, which are completely retracted to the reference surface 21, 6, 7, 13, and 14 when the knitting units perform knitting (circular formation), tucking, and circular irregularity with the cams 31 and 32 moving to the right, .

3, the right cam 23 guides the butt 4 and pushes the select jack 1 and thus the push-up (not shown) until the protrusion 8 engages with the recess 11. In this case, Thereby raising the jack 2.

Therefore, the butt 13 protrudes one step from the single-sided groove D1. When the carriage C1 is further moved to the right, the butt 4 is guided by the right cam 24 (FIG. 4) to further raise the select jack 1 so that the protruding portion 8 is in contact with the recess 12 Push up the push-up jack (2) until it engages.

Therefore, the butt 13 protrudes two steps from the single-sided groove D1.

As the carriage C1 moves further to the right, the knitting needle body 3 rises with its pushing-up jack 2 to its butt 13, which is guided by the cams 31 and 32. Thus, the formed ring moves downward through the latch 16 and the yarn is supplied to the hook 15.

Then the butt 13 is guided by the cams 34 and 35 so that the protruding portion 8 is released from the recesses 11 and 12 so that the knitting needle body 3 and the push-up jack 2 are lowered.

When the carriage C1 is tucked, the carriage C1 is moved to the state shown in Fig. 3, and the butts 13 are guided by the cam 30, so that the knitting needle body 3 rises together with the push-up jack 2. [ The knitted fabric body 3 is not raised very high with respect to the knitting needle bed B1 as in the knitting, so that the formed knitted fabric does not come off the latch 16.

5, the butt 5 is pushed by the solenoid 40 so that the butt 4 is completely retracted into the single-purpose slot D1 and the push-up jack 1 2) does not rise. The projection 8 does not engage any recesses 11 and 12.

Therefore, the carriage C1 moves toward the butt 13 retreated from the single-feeding slot D1, so that the knitting needle body 3 does not rise from the needle bed B1 and no yarn is supplied to the hook 15. [ Therefore, no polarization is formed.

The left cam 24 and the right cam 28 are protruded from the reference surface 21 and the right cam 24 and the left cam 24 are protruded from the reference surface 21 in order to move the carriage C1 to the left, The cam 28 retracts to the reference surface 21.

The cams 35 and 38 selectively protrude or retract and the degree of protrusion of the cams 31 and 32 at the reference surface 21 changes and the position of the cam 34 changes and the operation timing of the solenoid 40 As the pattern is changed, it is possible to change the movement of the knitting unit and to form different tissue patterns.

9, the knitting needle body 3 includes a knitting member 50 having a hook 15 and a latch 16, and a supporting member 51 having a supporting piece 9 and a resilient piece 10 It may be divided. In this arrangement, if the resilient piece 10 is broken, only the supporting member 51 needs to be replaced.

Therefore, the maintenance cost can be reduced.

As shown in Fig. 10, the supporting piece 9 and the elastic piece 10 may be separate members so that only the elastic piece 10 can be replaced. 11, the resilient piece 10 is coupled to the support piece 9 via the movable joint 52 and is tilted by the spring rod 53 toward the push-up jack 2. [ If the spring rod 53 is broken, it is necessary to replace the spring rod 53 only.

According to the present invention, the amount of protrusion of each butt in the single-entry groove is adjusted by adjusting the distance at which the select jack is raised, so that the cam is changed to engage with the butt, and thus the movement of the needle unit is also changed.

The knitting needle body is lifted with the push-up jack by engaging the projection in one recess.

Since there is no frictional resistance, no greater force is required to raise the knob body.

No additional mechanisms need to be provided in the carriage, such as a cam to guide the push-up jack, making the knitting machine less costly.

In the arrangement in which the knitting needle body is divided into the knitting needle member, the supporting piece, and the supporting member provided with the elastic piece, if the elastic piece is broken, only the supporting piece needs to be replaced. Therefore, repair costs are low.
