[Industrial applications]

 The present invention relates to a kind of sinker for a circular knitting machine, and more particularly, to preventing pile destruction and deterioration of knitted fabric quality due to deposition of cotton waste on the sinker or in the needle groove when forming a knitted fabric.

[0002]

[Prior art]

 Generally, a method of forming a loop on a pile or brushed ground is to guide two threads, a loop thread and a bottom thread, to the upper and lower positions of the sinker during the needle weaving process, and to pull the two threads when the needle hooks the loop. The pile yarns above the sinker are piled so that they cannot be pulled to the same height, and of course any stitch type is formed with the sinker.

The structure of the sinker has already been improved according to the stitch type or the design, and the stitch structure is divided into thick and fine (pile texture dense and coarse), but in both cases, the sinker is used. It can be a high quality knitted fabric. Currently, the sinker structure is designed for fine stitches, but improvements can be extended to thicker fabrics. The two types of sinkers are listed below and their disadvantages are described.

One of them is as shown in FIG. 1, and the sinker A is for knitting a relatively sparse opile structure. The point of the design is placed in the nose A1 and the nasal cistern A2, and when the sinker A is in the process of advancing, the nose A1 simultaneously penetrates multiple formed piles and receives the force of the newly formed pile. And make the pile length the same as the formed pile. The disadvantage of this type of sinker is that when the sinker A moves forward or backward, when the latch needle B performs a weaving operation, and when the latch needle B moves up and down and simultaneously forms a pile, cotton waste is generated. This cotton shavings remains on the latch needle B or the nasal tank A 2 part of the sinker A, and the pile tissue is relatively sparse, so that the area of the cotton shavings is relatively large. Although wind is blown from the outside of sinker A and latch needle B under the high-speed crossing work of A, since the distance between sinker A and sinker A is relatively close, the pile structure is If it becomes irregular or wrinkles and breaks easily, and wash sinker A or latch needle B at regular intervals to remove the cotton debris adhering to the needle groove, and then proceed with the subsequent work. That's all there is to it.

Another type of sinker is as shown in FIG. 2, and the sinker C structure is designed for a relatively dense pile tissue. In terms of its shape, a vertical inner concave tank C1 is formed on both sides of the sinker C, and the inner concave tank C1 covers all of the nose portion C2 and the nose tank C3 from top to bottom. The thickness of C1 is smaller than the total thickness of the sinker C, so that the pile structure becomes relatively dense when crossing with the latch needle B during the forward or backward process of the sinker C. Since the inner concave tub C1 is relatively thin and the working space of the latch needle B is relatively large, the chances of cotton shavings depositing on the latch needle B are relatively small, and only in the nasal tub C3. Further, since the pile is hung on the nasal tub C3, the cotton shavings are sequentially drawn out from the nasal cistern C3, and the drawn cotton shavings are vertically accumulated downward along the inner concave tub C1. As shown in FIG. 3, when the sinker C exits the needle groove and further advances, the cotton waste in the inner concave tank C1 also enters the needle groove by the advance of the sinker C, which makes it easier to close the needle groove. The work of the sinker C is easily affected, and there is a drawback that the life of the sinker C is shortened after long-term use. In this way, the sinker C solves the problem that the sinker A could not solve, and although it is said to be advantageous for the work of the latch needle B by opening the inner recess tank C 1, conversely, cotton waste is put in the needle groove. enter in. That is, since the thickness between the inner concave tubs C1 is smaller than the total thickness of the sinker C, and the sinker C also works in the needle groove, the installation of the inner concave tub C1 makes it easier for cotton waste to enter the needle groove, This hinders the work of C and causes inconsistency in the speed of each sinker C, which easily causes the problem that the pile structure is broken or wrinkles, and it takes a considerable amount of time and effort to wash the cylinder. Due to such problems, improvements in the structure are still required.

Further, many of the present inventions are presently studied and improved in the situation where cotton waste is generated, but most of them are improvements to the cylinder structure, and the expected effect is obtained. However, it was limited to the cylinder part and did not effectively solve the problem of cotton waste for sinker pieces.

[0007]

[Problems to be solved by the device]

 According to the present invention, symmetrical L-shaped tanks are formed at both upper end portions of the sinker, and the L-shaped tanks are provided higher than the needle groove of the cylinder, so that a relatively dense pile structure can be formed. The L-shaped tanks on both sides in sequence, and after the work operation before and after, the cotton waste is completely discharged to the outside of the sinker, which prevents the pile structure from being destroyed and affecting the quality, and the expected effect is obtained. Achievement is the main task.

[0008]

[Means for Solving the Problems]

 The sinker of the circular knitting machine of the present invention has laterally symmetrical L-shaped tanks formed on both sides of the upper end portion, and the thickness between the L-shaped tanks is set to be thinner than the entire thickness of the sinker. During the post-working process, the cotton dust is dropped onto the L-shaped tank from between the nose and the nasal tank, and then the cotton waste is discharged from the front end or the rear end of the sinker under high speed operation of the sinker front and rear operations. The L-shaped tank is provided in a laterally inclined shape or in a laterally arcuate shape depending on the knitted fabric form.

[0009]

[Action]

 According to the present invention, symmetrical L-shaped tanks are formed at both upper end portions of the sinker, and the L-shaped tanks are provided higher than the needle groove of the cylinder, so that a relatively dense pile structure can be formed. To the L-shaped tanks on both sides in sequence, and before and after the work operation, the cotton waste is completely discharged to the outside of the sinker, thereby preventing the pile structure from being destroyed and affecting the quality.

【Example】

 FIG. 4 is a perspective view of the sinker 1 of the present invention. Among them, the nose portion 11 is located at the top end of the sinker 1, the nose portion 11 is inclined from the back portion and extends to the front end, and the lower end has an arc surface, and is extended rearward to guide the nose tank 12. To draw. The sinker 1 is supported in the needle groove 21 of the cylinder 2, and the respective sinkers 1 are arranged in parallel and operate synchronously in the needle groove 21. Further, the upper end portion of the sinker 1 (including the nose portion 11 and the needle groove 21) has laterally L-shaped tanks 13 on both side surfaces thereof, and the L-shaped tanks 13 on both sides are installed symmetrically to each other. The corner of the tank 13 is arcuate, the thickness between the two symmetrical L-shaped tanks is smaller than the thickness of the entire sinker 1, and the sinker 1 is placed in the needle groove 21 of the cylinder 2. The lateral position of the L-shaped tank 13 is provided higher than the upper edge of the needle groove 21 (see FIGS. 5 and 6).

As shown in the perspective view of FIG. 5 and the side view of FIG. 6, after the sinker 1 is placed in the needle groove 21 of the cylinder 2, the entire thickness of the sinker 1 and the lateral width of the needle groove 21 are the same. It is convenient for working the sinker 1, and the position of the L-shaped tank is provided higher than the depth of the needle groove 21, so that when the sinker 1 works in the needle groove 21, the L-shaped tank 13 is exposed to the outside. Exposed. The focus of the design of the present invention is on the L-shaped tank 13 part, and when the latch needle B forms the pile tissue, the working position for grasping the thread is within the position of the nose 11 and the nose tank 12 from the front end. As seen, the L-shaped tank 13 of the sinker 1 and the front edge portion of the upper surface of the needle groove 21 have a step shape, and a working distance is preliminarily reserved between the L-shaped tank 13 and the upper surface of the needle groove 21.

FIGS. 7 and 8 are cross-work operation display diagrams of the sinker 1 and the latch needle B. When the sinker 1 and the latch needle B advance the knitting work, the position of the L-shaped tank 13 of the sinker 1 is located at the upper end of the needle groove 21, and the thickness between the L-shaped tanks 13 on both sides is relatively thin, that is, the pile structure is It is relatively dense, and the knitted fabric forming range is in the range of the positions of the nose 11 and nasal tank 12, and when the sinker 1 moves forward to form a pile, or when the latch needle B processes to grasp the pile. The generated cotton dust 3 is somewhat accumulated around the nose 11 and the nasal tank 12. At this time, the sinker 1 and the latch needle B are restored to their original state, and when proceeding to the next operation, the sinker 1 first advances to form a pile, and the latch needle B pulls down the pile, and the nose 11 and 12 nasal tanks of cotton waste 3 are sequentially drawn out, and the drawn cotton waste 3 directly falls into the L-shaped tanks 13 on both sides in the lateral direction. At this time, the pile is continuously pulled down to the latch needle B to an appropriate position, and at the same time, the sinker 1 also advances to the foremost end, and is blown by the wind from the blower tube outside the needle groove 21, so that the cotton waste 3 is removed by the needle. The sinker 1 and the latch needle B are blown out of the groove 21 and the sinker 1, and the sinker 1 and the latch needle B perform the following crossing operations in duplicate, and the cotton dust 3 generated in the pile forming process is first placed on the nose 11 and the nose tub 12 positions. Under the work of adhering and crossing the sinker 1 and the latch needle B, the cotton waste 3 is sequentially pulled down to the L-shaped tank 13 and the L-shaped tank 13 is installed sideways, so that the action is blocked and the cotton Since the waste 3 does not continuously fall into the needle groove 21 and the blower pipe equipment is provided on the outer periphery of the needle groove 21, the sinker 1 does not generate a situation of adhesion under high-speed work, and the operation is stopped to stop the needle groove 21. No need to wash

The L-shaped tank 13 of the present invention is designed to form a relatively dense pile structure, and naturally, there remains a problem in forming a relatively sparse pile structure. However, the design of the present invention is such that the sinker 1 has laterally-shaped L-shaped tanks 13 on both sides of the upper end thereof, and also has a different sinker 1 configuration according to the difference in work, for example, as shown in FIG. The L-shaped tank may be installed diagonally from the side and inclined from the rear end of the sinker toward the front end, and the cotton waste may be gradually and smoothly slid on the inclination. Further, as another form of the sinker of the present invention, the L-shaped tank may be changed from the lateral direction to an arc shape, and the front and rear ends may be set as the lowest points to form one arc shape. Both of the above-mentioned two embodiments eliminate the deposition and adhesion of cotton waste on the sinker or in the needle groove, and prevent the deterioration of the quality of the knitted fabric due to the destruction of the pile structure during the operation.
