TECHNICAL FIELD The present invention relates to a sock knitting machine, and more particularly, to a sock knitting machine having a sinker having a nonlinear step structure and an actuator thereof.

In general, a sock knitting machine mainly uses a sinker cover to knit pile stitches into a basic tissue.

As shown in Fig. 1, in the "sinker bed of the out-of-file pattern knitting sock knitting machine" disclosed in Registered Utility Model No. 0413445, the sinker 11 has a group of six or more sinkers having different sinker positions. It is mounted on the sinker bed (A ＇), and it moves back and forth according to the setting program to form a desired file pattern.

In the sinker bed A ′ of FIG. 1, a plurality of slots 13 are radially constant throughout their full width and thickness so that the sinker 11 can be advanced and retracted to operate with the needle (not shown). It is formed at intervals, the actuator (actuator) is operated in accordance with the set program to advance the corresponding operating lever (finger) to push the sinker end 12 of the corresponding sinker 11 radially to sink the sinker 11 By advancing through the slot 13 of the sinker bed A 'to the ring forming position, it works together with the knitting needle to form a loop to form a pile.

However, the conventional sinker bed A 'of this type is pushed forward to the pile knitting position by hitting the sinker end 12 of the sinker 11 by the normal control method according to the set program. The sinker 11 swings up and down by the striking force.

Particularly, when the sinker end 12 is at the top or bottom, the impact force of the actuator is limited to only a part of the sinker 11, so that the sinker is slightly shaken up and down by the moment. This becomes larger as the height of the sinker end 12 located at the top end away from the center of the sinker 11. For this reason, the shape of the knitted pile causes the sock knitting not to be the same as a whole but to be somewhat uneven, which causes the quality of the final product to deteriorate.

In addition, as shown in FIGS. 2 to 3, the sinker 7 disclosed in Patent No. 0573873, "Sinker cover for knitting out-file pattern of a loom knitting machine" has six sinker ends 7c linearly spaced at a predetermined interval. It is formed so that the pinker 8a of the actuator 8 escapes to the space between the sinker ends 7c.

Five escape spaces are required for the six sinker stages 7c for such an escape space. This increases the height of the rear end of the sinker, causing the fluctuation caused by the moment.

In order to reduce the behavior due to such a moment, the sinker end 7c should be formed at the position as close as possible to the center of the sinker 7.

Accordingly, the present invention was created to improve the problems of the conventional sock knitting machine as described above, by setting the operating direction of the actuator for operating the sinker in various ways so that the hopping space of the actuator can be easily secured The purpose is to provide.

In addition, by forming the RBI of the actuator adjacent to the center of the sinker, thereby reducing the moment acting on the sinker, the sinker can be slidably slid and provide a sock knitting machine that can lower the defective rate of the socks pile pattern. There is another object of the invention.

In order to achieve the object as described above, the sock knitting machine according to the present invention is provided with a plurality of sinker body portions at predetermined intervals on the sinker bed, and the operation portions which contact the sinker actuator at one end of each sinker body portion are different. Sinkers each formed in different positions so as not to overlap with the actuating portion of the sinker; A plurality of operating levers are provided to contact each of the operating portions of the plurality of sinkers, some of the plurality of operating levers are provided to behave in a different direction from the rest, and a plurality of driving means for operating the operating levers. One sinker actuator; characterized in that it comprises a.

Preferably, the sinker is provided with at least three or more at one sinker group with a predetermined distance from each other on the sinker bed,

Each of the sinker actuators constituting the one sinker group is formed at a position where the two sinkers 'operating portions are continuous and the openings are formed around the two sinkers' operating portions, with the sinker body parts coupled to the sinker bed. It is.

More preferably, the actuating lever of the actuator is adapted to behave in the opposite direction to another adjacent actuating lever.

Hereinafter, preferred embodiments of the sock knitting machine according to the present invention with reference to the accompanying drawings will be described in detail.

4 to 7, a sock knitting machine according to an embodiment of the present invention, a sinker provided in a plurality of groups on the sinker bed at a predetermined interval from each other, and a plurality of operating levers for operating the plurality of sinkers. It includes a sinker actuator 200 provided.

A plurality of sinkers are coupled to the cylinder upper sinker bed of the sock knitting machine along a circumferential direction with a predetermined distance from each other.

By the sinker actuator 200, a plurality of sinkers having different operating times form one sinker group, and sinker groups having the same configuration are continuously provided along the circumferential direction of the sinker bed.

Each of the sinkers includes a plurality of sinker body parts slidably provided along the radial direction of the sinker bed, and an actuating part contacting the sinker actuator 200 at one end of the sinker body part.

The sinkers of the sinker group are formed at different positions so that the horizontal position does not overlap with the operation portions of the other sinkers while the sinker body is seated on the sinker bed. That is, the sinkers of the single sinker group form a nonlinear step structure as a whole.

3 to 4, in this embodiment, one sinker group 100 is composed of four sinkers. The first sinker 110, the second sinker 120, the third sinker 130 and the fourth sinker 140 forming one sinker group 100 are sequentially provided in the circumferential direction of the sinker bed. And are provided at the same height as each other.

The first sinker 110 has a first operating portion 112 is formed at the top of the first sinker body portion 111, the second sinker 120 is the first sinker at the tip of the second sinker body portion 121 The second operating part 122 is formed below the first operating part 112, and the third sinker 130 is disposed below the second operating part 122 at the distal end of the third sinker body 131. The operation unit 132 is formed, and the fourth sinker 140 has a fourth operation unit 142 formed below the third operation unit 132 at the tip of the fourth sinker body 141.

As shown in FIG. 5, in the horizontal state in which the sinker group 100 is seated on the sinker bed, the second operation part 122 is positioned directly below the first operation part 112, and the second operation is performed. An opening is formed below the eastern part 122 and above the third operation part 132.

In addition, a fourth operating part 142 is positioned directly below the third operating part 132, and an opening is formed under the fourth operating part 142.

Here, the positions of the sinker beds of the first sinker 110 and the second sinker 120, the third sinker 130, and the fourth sinker 140 may be interchanged with each other. For example, unlike FIG. 3, the first sinker 110 and the fourth sinker 140 are positioned in the center, and the third sinker 130 is moved to the position of the fourth sinker 140 of FIG. ) May move to the position of the first sinker 110. Even in this case, as shown in FIG. 5, the sinkers provide the same side surface in the horizontal state seated on the sinker bed. This makes it possible to form various pile patterns.

As shown in FIG. 6, the opening part serves as a escape recess which the operating lever of the sinker actuator 200 escapes.

The sinker actuator 200 includes a plurality of operating levers that respectively contact the operating portions of the plurality of sinkers, and a plurality of driving means 260 for operating the operating levers.

The plurality of operation levers are provided at predetermined heights at different heights. The first operation lever 210 is positioned at the same height as the first operation unit 112 of the first sinker 110, and the second operation is performed at the same height as the second operation unit 122 of the second sinker 120. The lever 220 is positioned, the third actuating lever 230 is positioned at the same height as the third actuating part 132 of the third sinker 130, and the fourth actuating part 142 of the fourth sinker 140. The fourth operating lever 240 is located at the same height as. This is based on the height in the non-operational state where the actuating levers are not deformed.

Therefore, the first actuating lever 210 is driven in contact with the first actuating part 112 of the first sinker 110, and the second actuating lever 220 is the second actuating part of the second sinker 120. The third operation lever 230 drives the third operation unit 132 of the third sinker 130, and the fourth operation lever 240 drives the fourth operation of the fourth sinker 140. The operation unit 142 is driven.

The actuating levers are formed in a rod shape, and when electricity is applied, the actuating levers bend to one side about the turning point 250 and deform to operate the sinking actuating parts.

The plurality of operation levers operate independently through their respective driving means.

Among the plurality of operating levers, the first operating lever 210 and the second operating lever 220 are deformed in opposite directions, and the third operating lever 230 and the fourth operating lever 240 are opposite to each other. In the direction.

That is, as shown in FIG. 6, the first actuating lever 210 is positioned at the same height as the first actuating part 112, and is deformed upward of the first actuating part 112, and the second actuating lever. The 220 is positioned at the same height as the second operation part 122 and is deformed toward the lower opening of the second operation part 122.

Therefore, the first operating lever 210 and the second operating lever 220 can be avoided so as not to interfere with each other and to contact the operating portion of the sinker.

In addition, the third actuating lever 230 is positioned at the same height as the third actuating part 132 and is deformed toward the upper opening of the third actuating part 132, and the fourth actuating lever 240 is a fourth actuating part. Located at the same height as the operating unit 142 is deformed below the fourth operating unit (142).

Therefore, the third operating lever 230 and the fourth operating lever 240 can be avoided so as not to interfere with each other and to contact the operating portion of the sinker.

On the other hand, the second operating lever 220 and the third operating lever 230 is deformed to the same opening portion, but the space of the opening is secured large enough so that the two operating lever does not cause interference. That is, the opening portion forms a space at a height corresponding to twice the height of the operating portion.

Here, the height occupied by the four operating parts and the opening part is equal to the height occupied by the six operating parts.

As such, by setting the deformation directions of the four operating levers alternately, the four operating units can be operated in a space occupied by the six operating units. Therefore, it is possible to minimize the height of the tip of the sinker body portion due to the actuating portion of the sinker.
