Description

Circular knitting machine structure

The present invention relates to a circular knitting machine structure, in particular to a circular knitting machine structure that knits a yarn-changing plated loop by changing the position of the veil.

US11,136,698 discloses a knitting structure of a weft knitting machine that can change the yarn position. The knitting structure of the weft knitting machine enables each of the knitting needles to be controlled to perform a first narrowing trajectory and a second narrowing trajectory. , each time the knitting needles move along the first narrowing trajectory, each of the knitting needles knits a normal plating circle (Standard Plating) at a position within a needle hook without changing a veil and a base yarn. Each time the knitting needles move along the second narrowing trajectory, each of the knitting needles uses a needle latch to move the bottom yarn when an adjacent Schenck piece does not define the position of the veil and the bottom yarn. yarn, so that the base yarn is pushed by the nose of the Schenck piece, and the positions of the veil and the base yarn in the hook are changed, and an Interchanged Plating is knitted.

On the other hand, US9,834,871 discloses a method for a flat knitting machine to knit a yarn-changing plated loop on one side of the technical front. This method allows the Schenck sheet to be inserted while the knitting needle is in a second narrowing section. The front edge of the convex portion pushes the base yarn (i.e., the first color yarn described in the case) and the veil (i.e., the second color yarn described in the case) down at the same time for weaving, thereby forming the normal plating circle ( That is, the standard plating ring described in this case). When the machine head makes the knitting needle move in a yarn-changing and narrowing stroke, the Schenck piece can reach the intersection of the rear edge of the nose convex portion and the groove while the knitting needle is in the yarn-changing and narrowing stroke. The base yarn is lifted above the veil and then released for weaving to form the yarn replacement plated loop.

Although the aforementioned US11,136,698 and US9,834,871 can achieve the purpose of yarn replacement, both cases are achieved by changing the position of the base yarn. However, based on the current implementation of circular knitting machines, It is said that the space inside the needle hook of each knitting needle is limited. When the base yarn and the veil are fed into the needle hook, the base yarn will be closer to the position of the needle tongue, and the aforementioned position is the space inside the needle hook. The relatively narrow part makes the base yarn prone to problems with improper transposition. Furthermore, the Schenck piece disclosed in US9,834,871 uses two-dimensional motion to move the base yarn. For the Schenck piece of the circular knitting machine, it is unable to move in two dimensions.

The main purpose of the present invention is to solve the problem of unsmooth yarn changing resulting from existing implementations that mainly focus on changing the base yarn.

In order to achieve the above object, the present invention provides a circular knitting machine structure, including a plurality of knitting needles and a plurality of Schenck sheets. Each of the knitting needles has a needle hook. Each of the knitting needles is controlled to move in one of a first half-needle trajectory and a second half-needle trajectory. The first half-needle trajectory closes at a later time. At the second half-needle trajectory closing time point. The Schenck pieces correspond to each setting of the knitting needles. The Schenck pieces are uniform in shape. Each of the Schenck pieces has an abdomen, a nose connected to the abdomen and a nose between the abdomen and the The throat between the noses has an inclined surface and a plane connected to the inclined surface formed on the side of the nose away from the abdomen. Wherein, the knitting needles are fed with a veil and a base yarn each time they knit, and the veil is positioned higher than the base yarn in the needle hook. When one of the knitting needles moves along the first half-needle trajectory, During the looping process of one of the knitting needles, the veil does not support the inclined surface of one of the Schenck pieces located at the nose, and does not change the relationship between the base yarn and the base yarn in the needle hook. The relative position is to knit a normal plated circle. When one of the knitting needles moves along the second half-needle trajectory, and during the looping process of one of the knitting needles, the base yarn is in the Schenck pieces. In one of the throats, the veil briefly leans on the inclined surface of one of the Schenck pieces to change the relative position of the base yarn in the needle hook, forming a yarn-changing plating circle.

In one embodiment, each of the Schenck pieces includes a Schenck piece track, and the Schenck piece track includes a push-out section performed when each of the knitting needles is narrowed and a push-out section continued after the push-out section. recovery section.

In one embodiment, the circular knitting machine structure includes at least one knitting needle horn that provides multiple movement paths for the knitting needles, and at least one knitting needle that is controlled to drive each of the knitting needles in the first half needle trajectory and the second half needle path. A needle selector that moves one of the needle tracks.

In one embodiment, the circular knitting machine structure includes at least one Schenck blade angle that guides the movement of the Schenck blades.

In one embodiment, each of the knitting needles is controlled to move along the first half-needle trajectory, the second half-needle trajectory, and a plain stitch trajectory. Further, the circular knitting machine structure has at least one knitting needle angle that provides multiple movement paths for the knitting needles, and at least one controlled drive of each of the knitting needles to follow the first half-needle trajectory and the second half-needle trajectory. and a needle selector that moves one of the flat needle tracks.

According to the foregoing summary of the invention, compared with the conventional technology, the present invention has the following characteristics: in addition to allowing each of the knitting needles to move in one of the first half-needle trajectory and the second half-needle trajectory, the present invention , and by changing the position of the veil relative to the base yarn to avoid yarn jamming or uneven yarn changing during the yarn changing process.

The detailed description and technical content of the present invention are as follows with reference to the drawings: Please refer to Figures 1 to 5. The present invention provides a circular knitting machine structure 10. The circular knitting machine structure 10 includes a plurality of knitting needles 11 and a plurality of Schenck sheets 12. (Sinker). Each of the knitting needles 11 has a needle hook 111 and a needle tongue 112 that can perform a switching action relative to the needle hook 111. Each time the knitting needles 11 come out to hook yarn, the needle latch 112 is opened relative to the needle hook 111 so that the yarn can be fed into the needle hook 111 . Each time the knitting needles 11 are narrowed, the needle latch 112 will be affected by the previous plated loop that has been knitted and perform the closing action relative to the needle hook 111 . In the present invention, each of the knitting needles 11 is controlled to move in one of a first half-needle trajectory 20 and a second half-needle trajectory 21. The closing time point of the first half-needle trajectory 20 is later than that of the second half-needle trajectory. Half-needle trajectory 21 needle closing time point. To further explain, the circular knitting machine structure 10 includes at least one knitting needle horn 13 that defines each movable path of the knitting needles 11, and a needle selector 14 that determines the moving trajectories of the knitting needles 11. The knitting needle horn 13 may be composed of a plurality of horn blocks 131, and the shapes of the horn blocks 131 are not limited to being fixed. It can be designed according to path requirements. In addition, the needle selector 14 is connected to a controller (not shown in the figure) provided in the circular knitting machine, and the needle selector 14 selects the activities of the knitting needles 11 based on the signal sent by the controller according to the knitting process. The trajectory, that is, whether the knitting needles 11 move along the first half-needle trajectory 20 or the second half-needle trajectory 21, is determined by the needle selector 14 according to the signal sent by the controller.

On the other hand, please refer to Figures 4 to 7, the Schenck pieces 12 are respectively arranged corresponding to the knitting needles 11, the Schenck pieces 12 are uniform in shape, and each of the Schenck pieces 12 faces each other. An inclined surface 121 is formed on one side of each of the knitting needles 11 . Furthermore, the circular knitting machine structure 10 includes at least one Schenck piece angle 15 that guides the movement of the Schenck pieces 12. The Schenck pieces 12 are guided by the Schenck piece angle 15 and each has a Schenck piece track 22, The Schenck piece track 22 includes a push-out section 221 performed when the knitting needles 11 are each narrowed and a retraction section 222 following the push-out section 221. It should be understood that the push-out time point and the recovery time point of each of the Schenck pieces 12 of the present invention will not change due to the activities of the knitting needles 11, that is to say, no matter one of the knitting needles 11 is The movement of the first half needle track 20 or the second half needle track 21 does not change the movement of one of the Schenck pieces 12 that cooperates with one of the knitting needles 11 . Furthermore, each of the Schenck pieces 12 only performs one-dimensional movement, that is, each of the Schenck pieces 12 is only pushed out or retracted relative to one of the knitting needles 11 . The push-out action described in the present invention refers to the displacement of each of the Schenck sheets 12 toward the feeding point of the veil 30 and the base yarn 31. Similarly, the retracting action described in the present invention refers to the displacement of each of the Schenck sheets 12. Once the yarn is displaced away from the feeding point of the veil 30 and the base yarn 31 . Furthermore, the positions of the Schenck plates 12 in each section of the Schenck plate track 22 change continuously and are not fixed at a single position.

Referring to Figures 5 to 9, the knitting needles 11 are fed with a veil 30 and a base yarn 31 during each knitting operation. The veil 30 is positioned higher than the base yarn 31 in the needle hook 111. One of the knitting needles 11 is controlled by the needle selector 14 to move along the first half-needle trajectory 20. When moving, one of the knitting needles 11 is in the process of narrowing the needle to form a loop, and the veil 30 does not change the relative position of the base yarn 31 in the needle hook 111, as shown in Figures 6 and 7, and is knitted. A normal plating circle (Standard Plating) refers to a plating circle in which the veil 30 is located above the base yarn 31 when viewed from a technical front of a fabric. In addition, when one of the knitting needles 11 is controlled by the needle selector 14 and moves along the second half-needle trajectory 21, one of the knitting needles 11 is pulling the veil 30, and the veil 30 temporarily sustains the movement. The inclined surface 121 leaning against one of the Schenck sheets 12 causes the veil 30 to slip, and the veil 30 changes its relative position to the base yarn 31 in the needle hook 111. As shown in Figures 8 and 9, an Interchanged Plating is knitted. The Interchanged Plating refers to the plating where the veil 30 is located below the base yarn 31 when viewed from the front of the fabric. Moreover, the fabric woven by the present invention is as shown in Figure 10. Furthermore, the present invention changes the position of the veil 30 relative to the base yarn 31, because when the veil 30 is fed into the needle hook 111, its position is significantly higher than the base yarn 31 and is further away from the needle latch 112 and the needle hook 111. The connecting point of the needle hook 111 is far away and is located in a wider part of the needle hook 111, so that the yarn 30 will not get stuck or have problems with yarn changing during the position changing process.

Please refer to Figures 4 and 5 again. In one embodiment, each of the Schenck pieces 12 has an abdomen 122, a nose 123 connected to the abdomen 122, and a nose 123 between the abdomen 122 and the nose 123. The throat 124 is formed with the inclined surface 121 and a flat surface 125 connected to the inclined surface 121 on the side of the nose 123 away from the abdomen 122 . More specifically, when one of the knitting needles 11 moves along the second half-needle trajectory 21, one of the Schenck pieces 12 of the present invention will switch to the push-out section 221 in the Schenck piece trajectory 22. At the time of retracting the section 222, the inclined surface 121 of the nose 123 intervenes in the movement of the veil 30, causing the veil 30 to change its position.

Please refer to Figure 2, because the corner blocks 131 included in the knitting needle horn 13 of the present invention are different from the conventional ones, and each have a space 132 that allows multiple paths to be generated. The corner blocks 131 respectively have a plurality of the Space 132 forms are not limited to being identical.

Referring to FIG. 11 , in one embodiment, each of the knitting needles 11 can be controlled to move along the first half-needle trajectory 20 , the second half-needle trajectory 21 and a plain stitch trajectory 23 . Among them, the first half-needle trajectory 20 and the second half-needle trajectory 21 respectively cause the knitting needles 11 to seduce the veil 30 and the base yarn 31 to produce a plated loop, and the plain needle trajectory 23 causes the knitting needles 11 to seduce the veil 30 and the base yarn 31 to produce plated circles. The needles 11 each only attract the base yarn 31 to produce a plated loop. Based on this, when each of the knitting needles 11 is implemented with the flat needle track 23, a mesh (MESH) will be generated on the fabric, causing the fabric to appear in a pattern other than discoloration. The shape of the fabric is as shown in Figure 12 As shown, the areas 40 and 41 in Figure 12 are respectively the parts formed by the normal plating circle or the yarn-changing plating circle, and the part indicated by the reference numeral 42 is the mesh referred to in the present invention. In this way, the present invention can generate mesh at predetermined knitting points during the process of color-changing knitting, thereby adding changes to the fabric.

Furthermore, although the knitting needles 11 in this embodiment increase the movable part of the flat needle track 23, the knitting needle horns 13 used to guide the knitting needles 11 do not need to be replaced due to the design of the space 132 mentioned above. The knitting needles 11 can each move in one of the first half-needle trajectory 20 , the second half-needle trajectory 21 and the plain needle trajectory 23 only through the control of the needle selector 14 .

To sum up, the above is only a preferred embodiment of the present invention. It should not be used to limit the scope of the present invention. That is, all equivalent changes and modifications made according to the patent scope of the present invention should still belong to the present invention. patent coverage.
