Description

Socks knitting machine [0002]

The present invention relates to a sock knitting machine in which a needle jack mounted on a cylinder is lifted to knit socks.

In general, socks are western socks worn on the feet for warmth or courtesy. Socks are divided into short socks (socks / sox) reaching to the knees and stockings that come up to the thighs. These socks are divided into circular such as a knitting machine.

The sock knitting machine is a machine in which needles are arranged in a circular shape to rotate and knit, so that a tubular knitted fabric can be produced by forming a knitting loop by a knitting needle. A cylindrical needle cylinder is installed outside a cylinder shaft which is normally rotated by a motor, and a plurality of slots are arranged at predetermined intervals along the inner edge of the needle cylinder, and the needle is inserted and removed upwardly and downwardly for each slot, And a sinker for lowering the thread to form a loop is disposed at a right angle to the needle so as to be able to move forward and backward. As the needle cylinder rotates by the cylinder shaft, the needles move up and down, and at the same time, the sinker catches the yarn and knits. As the sinker moves back and forth, the loop is continuously made and the cylindrical knitted fabric such as socks, mufflers, paddles, toys, etc. is knitted while the yarn is inserted into the plurality of needles.

Hereinafter, a conventional sock knitting machine will be described in detail with reference to the accompanying drawings.

Fig. 1 is an exploded perspective view showing the construction of a conventional sock knitting machine, and Fig. 2 is a perspective view showing an operational shape of a conventional sock knitting machine.

As shown in FIG. 1, a conventional sock knitting machine includes a cylindrical cylinder 10 in which tens of insertion slits 12 are formed in a vertical direction on an outer circumferential surface thereof, an outer sinker ring (not shown) A needle 40 and a needle jack 42 which are inserted into the insertion slit 12 of the cylinder 10 so as to be capable of sliding motion and a needle jack 42 which is inserted into the insertion slit 12 of the cylinder 10, A base plate 60 coupled to the lower end of the shaft 80 and coupled to the base plate 60 so as to be in contact with a lower end of the needle jack 42. [ And a plurality of cam assemblies 72, 74, and 76, respectively.

The needles 40 and the needle jacks 42 are provided on the outer surface of the cylinder 10 so that the needle 40 and the needle jack 42 are not separated from the cylinder 10 and can slide along the insertion slit 12. [ A spring 14 for bringing the cylinder 42 into close contact with the cylinder 10 is further coupled.

When the cylinder 10 is rotated counterclockwise after the assembly of the sock knitting machine is completed as shown in Fig. 2, the needle jack 42, which is engaged with the outer surface of the cylinder 10, The needle 40 is reciprocated in the vertical direction, and the needle 40 is reciprocated in the vertical direction. In addition, the needle 40 is reciprocated in the vertical direction, The socks are knitted by the vertical reciprocating motion of the sock 40.

On the other hand, the number and position of the cam assemblies 72, 74, and 76 may be variously changed depending on the type of the sock to be knitted. Even if the number and the arrangement pattern are the same, The mounting position may need to be finely adjusted accordingly. However, in the conventional sock knitting machine constructed as described above, since the cam assemblies 72, 74 and 76 are fixedly coupled to the base plate 60, it is necessary to replace the base plate 60 when the kind of the yarn is changed .

In order to solve the above problem, a technique for adjusting the position of the cam assembly has been proposed. However, this has the problem that only the fine position of the cam assembly can be adjusted, and the number and location of the actuator are still limited.

In the following detailed description of the operation principle of the preferred embodiment of the present invention, if it is determined that a detailed description of known functions or configurations related to the related art may unnecessarily obscure the gist of the present invention, do.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals refer to like elements throughout. In the drawings, the same reference numerals are assigned to the same constituent elements as those of the conventional art, and the technical features and understanding of the present invention are provided by giving new reference numerals to constituent elements different from those of the conventional art.

The sock knitting machine generally elevates the needle jack 41 mounted on the outer circumferential surface slot 12 of the cylinder 10 so that the needle 40 connected to the needle jack 41 is also raised and lowered, It means a device for knitting socks with stitched yarn. In general, the needle jack 41 is structured such that a butt 42 protruded on one side is moved up and down by moving on the upper surface of the cam. The cam assembly included in the conventional sock knitting machine can be coupled to only one point of the base plate There is a problem that the base plate needs to be replaced when the position of the cam assembly is required according to the size and material of the yarn such as the bar and the thread thickness (e.g., rubber yarn).

Further, the base plate on which the cam assembly is installed is provided with an actuator having a plurality of blades for selectively lifting and lowering the needle jack 41 between the cam assemblies or around the cam assemblies, but a plurality of cam assemblies And the lifting body for lowering the needle, the number and the installation position thereof are limited, and the design of the sock and the knitting structure of the sock are also limited.

That is, conventionally, the sock knitting machine is structured such that the cam assembly mounted on the base plate is fixed at a position where it is impossible to adjust the position, and in the case of the cam assembly, the cam assembly itself is fixedly coupled to the base frame, A cam plate that is seated on the upper surface of the fixed block, and an engaging plate that covers the upper surface of the cam plate to fix the cam plate to the fixed block and occupies a certain volume, The number of installation and the installation position were limited.

Accordingly, the sock knitting machine 1000 according to the present invention completely replaces the function (function) of the conventional cam assembly and optimizes its structure to minimize the volume (volume) installed on the base plate, There is a primary purpose to increase the degree of freedom of the installation number and the installation position, and the configuration serving as a conventional cam assembly can be freely moved (adjusted) on the base plate, so that the base plate is not replaced, The secondary purpose is to make it possible to knit.

4 is an exploded perspective view showing a configuration of a sock knitting apparatus according to the present invention. 5 is an explanatory view showing a corresponding forming structure of a descending part according to a forming structure of a rising part according to the present invention. FIG. 6 is an enlarged view showing a state in which an actuator is installed on a base plate according to the present invention. FIG.

1 to 3, a sock knitting machine 1000 according to the present invention for achieving the above object is characterized in that a rising part 100 and a falling part 200 are formed instead of a conventional cam assembly, The structure of the base plate 300 on which the unit 100 and the actuator 80 are installed is characterized in that the base plate 300 has the structure shown in Fig.

Specifically, the lifting unit 100 is installed on the base plate 300 to raise the needle jack 41 in the same manner as the conventional cam assembly. The base plate 300 has a plurality of . At this time, the plurality of rising portions 100 formed on the base plate 300 may have different shapes, but all have the same configuration and structure.

The lifting unit 100 may include a fixed block 110, a lifting panel 120, and a first coupling plate 130.

The fixed block 110 is an arc-shaped block whose center point is located on the axis of rotation of the cylinder 10 and whose inner radius side curvature is the same as the curvature of the inner radius side edge C1 of the base plate 300. [ At this time, when the fixing block 110 is installed on the base plate 300, the inner surface of the fixing block 100 and the inner surface of the base plate 300 are arranged in a line. The width of the fixing block 110 in the same direction as the radial direction of the base plate 300 and the length of the base plate 300 in the circumferential direction can be freely formed, A width between the front end side of the actuator 80 provided on the base plate 300 and the base plate inner diameter side edge C1. That is, it may be preferable that the fixing block 110 is formed in a width such that the fixing block 110 can be positioned between the front end side of the actuator 80 and the inner plate side edge C1 of the base plate. In order to facilitate the movement of the actuator 80 on the base plate 300 without removing the fixing block 110 on the base plate 300. The related matters will be understood from the following description .

A plurality of position fixing holes 111 are formed in the fixing block 110 in a downward direction and are spaced apart from each other at a predetermined interval. To be fixed to the plate (300).

The lifting panel 120 is configured to contact the butt 42 located at the lower end side of the butt 42 formed in the needle jack 41 to raise the needle jack 41. In view of its role, There is a similar but structurally significant difference. Specifically, the lifting panel 420 is formed to have the same curvature as the inner diameter side edge C1 (= curvature of the fixed block inner diameter side) of the base plate, and both sides are formed in an arc shape having a downward- 121 are formed.

And is formed integrally with the fixing block 110 so as to be offset with respect to the inner diameter side edge of the fixing block 110 so that the bottom surface of the butt passes over the upper surface of the rising panel 120. [ At this time, the protruding portion 121 ensures reliable upward movement of the butt 42 over the lifting panel 120, thereby assuring the engagement of the needle 40 and the yarn lifted by the needle jack 41. That is, when the lifting panel 120 is formed simply and gently, the lifting of the needle 40 also gently rises to correspond to the lifting panel 120. At this time, the needle (the needle positioned at the apex of the rising panel), which has to be coupled with the yarn because the height difference between the adjacent needles 40 is not so large in the course of the gentle rising of the needle 40, The needle at the position prior to reaching the apex of the yarn is coupled with the yarn and comes to the vertex to cause a problem of coupling (double bonding) with the yarn. This makes it possible to achieve a significant rise of the needle 40 at the apex of the lifting panel 120 through the protrusion 121 of the lifting panel 120, So that it can be stabilized.

As shown in FIG. 5, the upward panel 120 may be divided into vertical panels 120a to 120c. The vertical panels 120a, 120b, 1 coupling grooves 122 may be formed.

At this time, generally, a plurality of cam assemblies of the sock knitting machine such as the prior art are formed, and the height and the structure of the cam surfaces of the plurality of cam assemblies are variously formed according to the design of the sock, the structure of the knitting structure, and the type of yarn. Conventionally, a cam assembly having a type of yarn corresponding to a sock design or knitting structure and a cam surface suitable for each role has been selected and fixed on a base plate.

For example, a rubber yarn for imparting elasticity to a normal yarn and an ankle or an ankle is applied to the sock. At this time, on the base plate, there are provided a plain yarn needle elevating cam assembly having a cam surface different in height and structure, Up cam assembly is constructed. In addition, depending on the design of the sock, the common yarn needle lift cam assembly and the rubber needle lift cam assembly can be configured in various numbers and combinations. That is, when the cam assemblies according to various yarns are combined and applied, there is an inconvenience that the cam assemblies are disassembled and assembled one by one.

However, since the rising panel 120 according to the present invention is divided into a plurality of pieces, the kind of the applied yarn and the separation of the divided rising panel 120 causes a change in the rising height of the corresponding needle jack 40 Thus, there is no need to install and release the entire structure for raising the needle jack 40 on the base plate as in the conventional art. In addition, since the plurality of rising portions 100 installed on the base plate 300 are all the same structure, the rising portion 100 can be easily manufactured, managed, and repaired.

The first coupling plate 130 fixes the divided ascending panels 120a to 120c from the outside and is formed to have a length not exceeding the height of the finally coupled lifting panel 120, The coupling holes 131 may be formed at positions corresponding to the positions of the first coupling grooves 122 formed in the first through fourth coupling holes 120a through 120c. The first coupling plate 130 may fix the rising panels 120a to 120c divided by a separate fixing member 132 such as a bolt to one panel, The interference with the butt 42 does not occur even when the lift panel 120 is coupled to the lift panel 120 as it is formed on the outer side of the actuator 120 and the actuator 80 does not interfere with movement of the actuator 80. [

The descending part 200 is formed at a lower point of the outer sinker ring 20 of the cylinder 10 in a rim structure for lowering the needle jack 41 raised by the ascending part 100. The lower part 200 is formed by a descending part 210 having a circular rim shape whose lower end has a curvature corresponding to the curvature of the rising panel 120 and a lower part formed by the extended rim 220 and the second engaging plate 230 do.

The lowering groove 210 is formed in a generally cylindrical shape and a lowering groove 211 having a shape corresponding to the rising panel 120 of the rising portion 100 is formed at a position corresponding to the rising portion 100 The lower end butt 40 rises while riding over the upturn panel 120. When the lower end butt 40 rises over the upturn panel 120, The upper butt 40 of the needle jack 41 is naturally moved along the lower groove 211 and can be stably lowered again. And the upper butt 40 of the lowered needle jack 41 moves along the lower surface of the downward groove 211. A second coupling groove 212 for coupling the second coupling plate to the extended rim is formed in the lower groove forming portion of the lowering groove.

The extended rim 220 is mounted to the lowering groove 121 and has a structure similar to that of the rising panels 120a to 120c divided according to the shape of the rising panel 120 and the shape of the lowering groove 211, Shape. However, the divided extended rims 220a to 220b are mirror-symmetrically installed with the divided rising panels 120a to 120c.

For example, assuming that the upward panel 120 and the downward groove 211 are divided into three (lower end upper end) divided structures, the upward panel (lower end) 120a fixed to the fixed block 110 and the Two split ramp panels 120b and 120c are additionally configured and two further rims 220a and 220b are included, including the lower ramp 211 of the ramp 210.

5A, when the lifting panel 120 is in a state in which both the lower end and the upper end of the lifting panel 120 are engaged with each other, the lifting recess 211 is removed in the recess 220a and the upper extension rim 220b, Only the lower end 120a of the lifting panel 120 exists as shown in FIG. 5 (c) The upper end rims 220a and 220b are further engaged so that the distance between the rising panel 120 and the lowering groove 211 can be kept constant. In the extended rims 220a and 220b, the second coupling grooves 212 may be formed in the same line as the second coupling grooves formed in the descending grooves, like the divided ascending panels 120a to 120c.

The second coupling plate 230 has the same purpose and structure as the first coupling plate 130 formed on the lifting panel 120 by fixing the extended rim 220 coupled to the lifting frame 210.

The auxiliary lifting groove 213 for lowering the needle jack 40 lifted by the actuator 80 may be additionally formed around the lifting groove 211. [ At this time, a separate extended rim 220 is not coupled to the auxiliary descending groove 213, and may be formed in a smaller size than the descending groove 211.

The lifting portion 100 and the lowering portion 200 as described above assure that reliable and stable upward and downward movement of the needle jack 41 can be achieved and at the same time that the needle jack 41 Stable rising and falling can be achieved. The lifting portion 100 occupies a very small footprint on the base plate 300 and is not installed on the base plate 300 in the case of the lifting portion 200. As a result, It is possible to secure a large installation area (an empty area in which other structures can be installed) of the actuator 80, thereby greatly improving the degree of freedom of installation of the actuator 80. [

The base plate 300 according to the present invention has a generally corresponding structure to that of the conventional art. However, the base plate 300 according to the present invention has the raised portion mounting hole 310 and the actuator mounting groove 320 There is a difference.

Specifically, the elevating portion mounting groove 310 is provided for setting the mounting positions of the elevating portion 100 and the actuator 80 variously. The elevating portion mounting groove 310 is formed at equal intervals along the inner circumferential edge C1 of the base plate 300 And a plurality of these are continuously formed. Therefore, when one rising part 100 is installed in a state where the plurality of rising parts 100 are installed at a distance from each other, the rising part 100 can be installed by counting the rising part mounting holes 310 have. In other words, conventionally, since the installation grooves for installing the respective cam assemblies have been determined, they have to be always installed in the same place. However, the base plate 300 according to the present invention can be provided with the rising portions 100 at various positions, There is an advantage that other elevating portions 100 can be easily installed without additional measurement when the elevating portion 100 is installed.

The actuator mounting groove 320 is divided into an actuator moving groove 321 and an actuator fixing hole 322 by grooves for mounting and fixing the actuator 80.

The actuator moving groove 321 has a length corresponding to the length of the actuator 80 (the length in the radial direction of the base plate) and has a predetermined depth from the upper surface of the base plate 300, As shown in FIG. The lower end of the actuator 80 is partially inserted and the actuator 80 can move along the actuator moving groove 321 about the cylinder 10. At this time, the actuator 80 that moves along the actuator moving groove 321 has a structure corresponding to the structure of the actuator moving groove (the curved shape is the same as that of the actuator moving groove on the front and rear end sides and can be inserted and moved in the moving groove of the actuator) (Not shown) and movable along the actuator moving groove 321. The actuator moving block 321 may be fixed to the actuator fixing block (not shown)

The actuator fixing hole 322 is for fixing the actuator 80 moved along the actuator moving groove 321. The actuator fixing hole 322 is formed continuously along the actuator moving groove 321 at a mutually set interval on the bottom surface, Are fixed to each other through bolts or the like.

In this case, in order to fix the actuator 80, separate fixing holes may be continuously formed and integrated into one slot structure. However, if the fixing holes are formed in a slot shape, It may be desirable to form a plurality of independent actuator fixing holes 322 at predetermined intervals as described herein.

As the actuator mounting groove 320 moves along the actuator moving groove 321 when the actuator 80 is installed, it is easy to adjust the position of the actuator 80 and the position of the additional actuator 80, It is not necessary to separately adjust the gap between the actuator 10 and the cylinder 10 in positional adjustment. Since the actuator fixing holes 322 are formed at the predetermined positions at the predetermined positions during the installation of the plurality of actuators 80, the spacing between the actuators 80 at the time of installing the adjacent actuators 80 is automatically The installation and fixing can be performed in a short time.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings, and all or some of the embodiments may be selectively combined so that various modifications may be made.
