2, two circular needles N1 and N2 are arranged so as to intersect orthogonally with each other as shown in FIG. 2, and the circular knitting machine is referred to as a double circular knitting machine. When a needle N2 ) Is arranged so as to move up and down and is knitted, it is called a single circular knitting machine.

However, these single and double yarns are different from each other in knitting purpose, and the positions of the needles N1 and N2 are different from each other, so that they can not be singly used in a double state because they are caught by interference in a single operation.

As described above, since the double knitting machine and the single knitting machine can not be used in the circular knitting machine of the present structure, they are made of separate machines, which causes a disadvantage that the cost is increased and the installation space is excessively increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems in the prior art, and an object of the present invention is to provide a single circular knitting machine and a double circular knitting machine, each having a different structure according to the number of needles to be knitted, So that it can be used singly or doubly, thereby increasing the convenience of use and helping to reduce the cost of the double circular dual circular knitting machine.

The present invention provides, as means for achieving the above object, a circular table, a plurality of vertical needles provided along the radial direction of the inner diameter of the circular table, a dial installed inside the circular table, A bushing type connecting rod connecting the rotary motor to rotate the dial, a cylindrical fixing table for fixing the bushing type connecting rod, and a supporting table for fixing the cylindrical fixing table, the circular knitting machine comprising: A combination adjusting motor fixed on the cylindrical fixing table; A first gear fixed to a motor rotation shaft of the combination adjusting motor; A tooth surface formed on a part of a length of an outer peripheral surface of the bushing type connecting rod; And a second gear whose inner diameter is screwed to the tooth surface and whose outer diameter is coupled with the first gear in a tooth-like manner. By raising and lowering the bushing-type link in accordance with the rotating direction of the combined- And the upper and lower portions of the double-single-ended circular knitting machine can be vertically moved.

At this time, the outer diameter of the second gear coupled to the first gear is formed to have a flat gear engagement structure, and the first gear is also embedded in the upper surface of the cylindrical fixing table at a predetermined depth.

Also, the outer diameter of the second gear coupled to the first gear is formed by a bevel gear coupling structure, and the first gear is also embedded in an upper surface of the cylindrical fixing table at a predetermined depth.

In addition, the second gear is characterized in that the longitudinal section thereof is formed of a cylinder having a shape of 'ㅗ' and is fixed in such a manner as to be fitted to the bushing-like connection, thereby eliminating interference with peripheral components.

According to the present invention, it is possible to reduce the cost, improve the convenience, and effectively utilize the space occupied by the equipment by configuring the single circular knitting machine to be double and single.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

4 to 6, the double-single-seat circular knitting machine according to the present invention includes a circular table 100.

A vertical cam 110 is provided on an inner diameter side of the circular table 100 and a vertical needle 120 is connected to the vertical cam 110. The vertical needle 110 is moved in a vertical direction do.

A dial 200 is installed in the circular table 100.

The dial 200 is provided with a plurality of horizontal cams 210 at regular intervals along the radial direction and a horizontal needle 220 is connected to the horizontal cam 210, And is knitted while moving in the horizontal direction.

Therefore, in the case of the double circular knitting machine, the vertical needle 120 and the horizontal needle 220 are knitted while being perpendicular to each other.

At this time, the dial 200 is connected to the rotation axis R1 through a bushing connection 230 so that the dial 200 can be rotated by the rotation motor M1.

In the present invention, the dial 200 is lifted and lowered in the general structure of the double circular knitting machine, so that the dial 200 is lifted up to a certain height when used as a single circular knitting machine and returned to its original position when used as a double circular knitting machine. So that a single circular knitting machine can be used and double and single can be used as needed.

To this end, the present invention further includes a combination adjusting motor 250 on a cylindrical fixing table 240 that rotatably supports the dial 200 and fixes the dial 200 to the supporting table S.

The combination adjusting motor 250 is configured to transmit the rotational force to the first gear 260 fixed on the motor rotation axis R2. In particular, the cylindrical fixing rod 240 moves on the support S, It is fixed so that it remains firmly stable.

In addition, the first gear 260 is preferably a spur gear, and it is particularly preferable to minimize interference with adjacent components by fixing the first gear 260 in a state of being embedded at a certain depth in the upper surface of the cylindrical fixing table 240.

The first gear 260 is meshed with the second gear 270.

The second gear 270 is a two-side gear having teeth formed on both the outer and inner circumferential surfaces thereof. The gear teeth of the outer circumferential surface of the first gear 260 are meshingly engaged with each other. It is preferred to have a bondable tooth profile.

The teeth formed on the inner circumferential surface of the second gear 270 are coupled with the outer circumferential surface of the bushing-type connecting rod 230. To this end, a tooth surface 280 is formed at a position corresponding to the outer circumferential surface of the bushing- .

In this case, the tooth surface 280 is a screw type, and is a screw coupling type configured to be able to move by a predetermined pitch in accordance with the rotation of the second gear 270.

More preferably, the second gear 270 is fixed in such a manner that the second gear 270 is fitted to the bushing-type link 230 by constructing the second gear 270 in the shape of a cylinder having a generally vertical cross-section, minimizing interference.

In addition, the first gear 270 and the tooth 280 may be helically coupled to each other. In this case, the first gear 270 and the tooth 280 may be precisely positioned through precise power transmission.

In addition, the first gear 260 and the second gear 270 may have a bevel gear coupling structure to transmit a large force.

Accordingly, when the combined adjustment motor 250 rotates in a predetermined direction, the rotational force is transmitted to the motor rotation axis R2, the first gear 260, the second gear 270, and the bushing link 270, The bushing-type connecting rod 270, which receives the rotational force, moves upward by a predetermined pitch with respect to the cylindrical holding rod 240.

This operation eventually lifts the dial 200 to which the bushing type connection 230 is connected so that the horizontal needle 220 connected to the horizontal cam 210 of the dial 200 is rotated by the vertical needle 120).

Therefore, the vertical needle 120 can be used as a single circular knitting machine as shown in FIGS.

In this case, a sinker pin 140 is inserted to adjust the up and down movement of the vertical needle 120. The sinker pin 140 is connected to all the vertical needles 120 ).

The sinker pin 140 generally refers to a thin steel sheet placed between a knitting needle (single needle) and a knitting needle. The knitting needle is supported by a knitting needle in a forward and backward motion with respect to a knitting machine, It serves to catch the falling.

On the other hand, when the dial 200 is used as a double circular knitting machine, it can be easily implemented by returning the dial 200 to its original position.

In other words, the dial 200 can be lifted only when the dial 200 is in a down position, that is, when a single circular knitting machine is required when using the double circular knitting machine, and then inserted into the respective sinker pins 140 and used as a single circular knitting machine .

Of course, it is natural that all of the sinker pins 140 inserted for the single circular knitting machine should be removed when returning to the double circular knitting machine described above.

By doing so, it becomes possible to realize a dual-purpose circular knitting machine capable of using both a single and a double with a single circular knitting machine, thereby achieving an efficient installation space and a cost reduction effect.
