The present invention relates to a sinker cover for knitting an out-file pattern of a sock knitting machine, and more particularly, to an improved invention of the applicant Patent No. 573873 (Registration Date: 2006.4.19).

In contrast to the monotonous socks that protect the feet and keep warm, consumers nowadays prefer socks that are versatile and have a good appearance. In response to this trend, the function of socks is gradually diversified, so that the socks are knitted with a pile stitch on the entire inner surface of the socks or on the soles or heels of the socks to protect the feet more perfectly and increase the warming effect. To improve the quality of.

Up to now, the sinker cover as shown in FIGS. 1 and 2 is mainly used to organize the pile structure on the inner surface of the sock using a general sock knitting machine. In the conventionally known sinker cover 1 shown in Figs. 1 and 2, the central cam 2 and the loop are piled up so that they do not come off from the noses 3a and 3b of the respective sinkers 3 and 3 '. The sinker cams 4a, 4b and 5, which contribute to the formation of the recesses, are spaced apart from the central cam 2 around the base 1a of the sinker cover 1 so as to provide a sinker path between these cams. 6) is formed, and the sinker 3 and 3 'of long and different lengths of the sinker end 3c are provided to move along the sinker passage 6. Moreover, even if the height is corresponding to the sinker end 3c of these sinkers 3 and 3 ', the sinker actuating cam 7 with the same two structure is attached to the base 1a of the sinker cover 1. The sinker 3 and 3 'are operated while moving back and forth as shown by the arrow 1. By the operation of the sinker actuating cam (7), two sinker actuating cams (7) actuating corresponding to each sinker (3) (3 ') when the sinker (3) (3') moves along the sinker passage (6). The sinker end 3c of the sinker 3 or 3 'is pushed radially further toward the center of the sinker cover 1 than the general flat tissue is knitted by the action of any one of The two sinker actuating cams 7 prevent shaking during the operation of the sinkers 3 and 3 'when forming piles, so that pile structures can be uniformly formed.

In this way, the sinker cover 1 of the conventional sock knitting machine usually forms piles on the heel portion and other necessary portions inside the socks.

However, the pile structure formed by the conventional sinker cover (1) can be formed only in the form of a rectangular shape, such as a straight or rectangular or square with the inner surface of the sock is limited in the pattern and position that can be expressed and the curved shape such as circles, ellipses It was impossible to form pile tissues, and there was a problem in that it could not be applied to computerized automatic sock knitting machines using multi-sink sinkers with 6 or more sinker ends.

In order to solve the conventional problems as described above, the applicant uses a sinker having a sinker stage of six or more stages so as to form a file pattern of all shapes such as curves and straight lines on the inner or outer surface of the sock. In the sinker cover for knitting an out pile pattern of a hosiery knitting machine configured to be operated in cooperation with an actuator around the inner circumference of the base, the base of the sinker cover has a c-shaped cutout at one side. The cam is provided with expansion and contraction portions having different widths from the center to both sides, and the surface is partially cut so that two sinker cams are inserted between the base and the base of the sinker cover, respectively. Forming grooves and protrusions provided; Protruding jaw is formed on the base front surface of the sinker cover, to control the operation of the sinker to accurately control the operation, and the operating rod is moved back and forth in accordance with the movement of the operation unit provided at the other end from the fixed end, The protruding jaw is moved back and forth to move forward or backward in the groove according to the movement of the operating rod in the state inserted adjacent to the sinker cam is fixed to the groove for knitting out pile pattern of the sock knitting machine The sinker cover was filed and registered under patent application No. 2006-4866 (filed date: January 1, 2006).

The applicant's pre-registration can be applied to a computerized so-called automatic sock knitting machine using a multi-stage sinker to produce high quality socks by expressing all the desired patterns on the inside and outside of the socks without being concerned with the shape of the pattern. In addition, by reducing the number of sinker cams provided in the sinker cover and inserting the inside of the sinker cam and moving the protruding jaw of the actuating rod radially toward the center of the sinker cover, the structure is simple and easy to manufacture. Accurately guide and control the stroke to increase the operating accuracy of the sinker. Even though the speed (rpm) of the sock knitting machine is increased, the sinker operation can be accurately performed because the error range is reduced in the sinking distance according to the forming angle of the central cam. Can form a certain shape of the file as a whole socks, plus circles or songs Got such without regard to the form of the inner surface of a uniform pattern files of various shapes sock can be expressed in the exterior as well as the effect that design can produce high socks.

However, in the applicant's pre-registration, since the half of the pile and half of the plain weave were selected and knitted using the actuator when the instep and the bottom of the general socks were knitted, structurally the pile and the plain weave It was difficult to organize them at high speed, resulting in poor production and long knitting time.

An object of the present invention was improved to improve the shortcomings of the applicant's patent No. 573873, and when the instep and the bottom of the general socks are selected by half half pile and half plain weave, pile pile and The present invention provides a sinker cover for out-file pattern knitting of a sock knitting machine, which enables to knit plain weaves at a higher speed, and also greatly increases the production of general socks and at the same time significantly shortens the knitting time.

In order to achieve the above object, the present invention assembles the slider so as to move forward and backward on the bottom of the sinker cover, and fixes the actuating cam for forming the anti-pile in the front lower part of the slider, and moves the actuating cam to the rear of the slide. An air cylinder to connect the tensioning spring to advance the actuating cam on both sides of the sinker cover and the slider, and the anti-pile forming protrusion which is operated in cooperation with the actuating cam on top of the sinkers corresponding to half of the sinkers. It is formed.

Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.

As shown in FIGS. 3 to 10B, an inner or outer surface of a sock knitting machine using a sinker 10 having six or more sinker ends 11, as shown in FIGS. 3 to 10B. Socks knitting machine configured to be operated in cooperation with the actuator 40 and the central cam 30 is mounted around the inner circumference of the base 21 of the sinker cover 20 so that the file pattern of all shapes such as curve, straight line, etc. In the out-file pattern knitting sinker cover 20, the base portion 21 of the sinker cover 20 is provided with a c-shaped incision 22 on one side, the center cam 30 has a surface Two sinkers cams 50 and 51 are partially inserted and partially inserted between the bases 21 of the sinker cover 20 and the grooves 31 and the protrusions 32 provided on the left and right sides of the central cam 30. ); On the front surface of the base 21 of the sinker cover 20, a projection jaw 61 for precisely controlling the operation by adjusting the stroke of the sinker 10 is formed, and the operation part provided at the other end from the fixed end ( 62 is provided with an actuating rod 60 which is moved back and forth according to the movement of the 62, wherein the protruding jaw 61 is inserted adjacent to the sinker cam 50 inserted into and fixed to the groove 31. As the rod 60 moves forward and backward to move forward or backward in the groove 31, it is the same as the applicant's prior registration.

However, in the present invention, as shown in Figs. 3 to 10b, a slider groove 23 formed at the bottom of the sinker cover 20 and having a long hole 23a; A slider (70) having a guide pin (71) fitted to the slider hole (23a) to be movable back and forth in the slider groove (23); Semi-pile forming actuating cam 80 is fixed to the front lower portion of the slider 70; A pedestal (90) attached to the bottom of the sinker cover (20) to support the slide (70); An air cylinder 100 fixed to the rear of the slider 70 and having a piston 110 in contact with the pedestal 90; A tension spring (200) connected to both sides of the sinker cover (20) and the slider (70); The anti-pile forming protrusions 12 which protrude to the upper portion of the sinkers 10 corresponding to half of the sinkers 10 and operate in cooperation with the operation cam 80 are characterized in that the technical configuration. do.

Here, the slider groove 23 is formed at the bottom of one side of the sinker cover 20 as shown in FIG. 5, and the slider groove 23 guides the forward and backward movement of the slider 70. At this time, a long hole (23a) is formed in the slider 23.

The slider 70 is inserted into the slider groove 23 of the sinker cover 20 so as to be movable back and forth. The slider 70 supports the actuating cam 80 while moving the actuating cam 80 back and forth. . In this case, a guide pin 71 is inserted into the long hole 23a of the slide groove 23 at the upper portion of the slider 70. Therefore, the long hole 23a guides the forward and backward movement of the guide pin 71 and limits the forward and backward movement distance of the guide pin 71.

The actuating cam 80 is integrally and firmly fixed to the front lower part of the slider 70 by screwing, and the actuating cam 80 has an upper portion of the sinkers 10 corresponding to half of the sinkers 10. Protruding projection 12 is caught. At this time, the actuating cam 80 moves only the sinkers 10 in which the protrusions 12 are formed so that the pile is formed only at one part of the instep or the bottom when the general socks are knitted, and the actuating cam 80 is For the instep and bottom of ordinary socks, half is used as a pile pile and half is a plain weave.

The pedestal 90 is firmly attached to the bottom of the sinker cover 20 by screwing, and the pedestal 90 supports the slide 70. In this case, the piston 110 of the air cylinder 100 is in contact with the pedestal 90.

The air cylinder 100 is integrally and firmly fixed to the rear of the slider 70 to move the operation cam 80 to the rear in normal (when not forming a semi-pile), such that of the air cylinder 100 The piston 110 is in contact with the pedestal 90. At this time, the air cylinder 100 is automatically controlled by a computer program of the sock knitting machine. Therefore, normally, since the air cylinder 100 is 'on' and air is supplied to the piston 110, as shown in FIGS. 7A and 9A and 9B, the operation cam 80 is maintained in a rearwardly moved state. On the other hand, when the half-pile of the general socks, the air cylinder 100 is 'off', so the air is not supplied to the piston 110, the actuating cam 80 by the restoring force of both tension springs 200 is shown in FIG. As shown in FIG. 10A, only the sinkers 10 in which the protrusions 12 are formed while moving forward are moved forward to form a half pile.

The tension spring 200 moves the operation cam 80 forward when the air cylinder 100 is in an 'off' state, and the tension spring 200 is connected to both the sinker cover 20 and the slider 70 at both ends thereof. Are each connected. At this time, the tension spring 200 is installed on both sides of the slider 70, respectively. Therefore, normally, when the air cylinder 100 is 'on' and air is supplied to the piston 110, as shown in FIGS. 7A and 9A and 9B, the piston 110 protrudes, and as a result, the tension spring 200 is pulled. While the air cylinder 100, the slider 70, the operation cam 80, the sinker 10 is maintained in the rear moved state, while the air cylinder 100 is 'off' when forming a half pile of the general socks When the air is not supplied to the piston 110, the sinker 10 in which the air cylinder 100, the slider 70, the operation cam 80, and the protrusion 12 are formed by the restoring force of the tension spring 200 is illustrated in FIG. 10A. As shown in the figure, the state of moving forward is maintained.

The protrusion 12 protrudes to the upper portion of the sinkers 10 corresponding to half of the sinkers 10, that is, in the case of all 200 sinkers 10 installed in the hosiery knitting machine, for example, 100 according to the present invention. The anti-pile forming protrusions 12 are formed only on the two sinkers 10 as shown in FIG. 8A, and the protrusions 12 are not formed on the remaining 100 sinkers 10 as shown in FIG. 8B. Therefore, when the actuating cam 80 moves forward when forming the semipile according to the present invention, only the sinker 10 in which the protrusion 12 is formed moves forward as shown in FIG. 10A, and the protrusion 12 as shown in FIG. 10B. Since the sinker 10 that is not formed is not moved forward, half of the insole and the bottom of the general socks are knitted in a pile and half are knitted in a plain weave.

On the other hand, according to an embodiment of the present invention, the central cam 30 is characterized in that the preliminary protrusion 33 formed in the inclined surface so as to pre-slide the sinker 10 in advance. According to this embodiment of the present invention, since the preliminary protrusion 33 is formed as an inclined surface to advance the sinker 10 in advance, the finger size and weight of the actuator 40 can be reduced.

When described in detail according to the accompanying drawings the overall operating relationship of the present invention configured as follows.

First, the air cylinder 100 is 'on' by automatic control of the sock knitting machine computer program in the case of not forming the semi-pile, and the air is supplied to the piston 110. As a result, in FIGS. 7A and 9A and 9B, As the piston 110 protrudes as shown in the drawing, as a result, in this state, the air cylinder 100, the slider 70, the operating cam 80, and the sinker 10 move backward while pulling the tension springs 200 on both sides. Will remain intact. Therefore, in this state it is possible to organize a variety of file patterns while controlling the sock knitting machine in the same action as the applicant's pre-registration.

Next, when the semi-pile of the general socks is formed, the air cylinder 100 is 'off' by automatic control of the sock knitting machine computer program, and thus the air is not supplied to the piston 110, and thus in this state, FIGS. 7B and FIG. As in 10a and 10b, the air cylinder 100, the slider 70, and the operation cam 80 are simultaneously moved forward by the restoring force of both tension springs 200, and at the same time, the protrusions are made by the operation cam 80. Only half of the sinker 10 in which the 12 is formed is moved forward to form a pile as in FIG. 10A, and the sinker 10 in which the remaining protrusions 12 are not formed is not moved forward as in FIG. 10B. As a result, when the instep and the bottom of the general socks are knitted, half is piled and half is laid.

On the other hand, as the applicant advances the protruding jaw 61 of the operating rod 60 as in the prior registration of the sinker 10 because all move forward, both the instep and the bottom of the socks are knitted in the pile.

Accordingly, according to the present invention, when the instep and the bottom of the general socks are selected by knitting half and half plain weave, and half half plain weave, mechanical half-pile formation without using the electronic actuator 40, such as pre-registration Forming the pile weave and plain weave using the operation cam 80 has the advantage that can be knitted more high-speed than the general semi-pile socks compared to the electronic.

In addition, according to the present invention, since the pile weave and plain weave can be knitted at a high speed by using the anti-pile forming operation cam 80 as described above, as a result, it is possible to greatly increase the production of general socks through the knitting at the same time. There is an advantage that can greatly reduce the time.

As described above, the sinker cover for knitting an out-pile pattern of the sock knitting machine according to the present invention uses an actuating cam when selecting the half of the pile and the half of the plain weave when knitting the instep and the bottom of the general sock. Thus, the pile weave and plain weave can be knitted at a higher speed, and through this, it is a very useful invention that can greatly increase the production amount of general socks and at the same time greatly reduce the knitting time.
