Description

A double-head knitting process for a glove machine Technical Field

[0001] The present invention relates to the field of glove knitting machines, and in particular to a double-head knitting process for a glove knitting machine. Background Art

[0002] The basic structure of the computer glove machine is: between the left and right bases, there are front and rear needle beds, the needle beds are equipped with liftable knitting needles, the front and rear heads are both equipped with cam bases, various cams are arranged on the cam bases, and the needle selection roller cooperates with the cam bases to select and cast on the knitting needles to complete various knitting functions.

[0003] Taking the applicant's prior patent "CN208167242U" as an example, existing computerized glove knitting machines generally connect the front and rear heads through a head connection device, which is driven by a drive device to achieve synchronous movement of the front and rear heads (in the prior patent, the front head is driven by the rear head).

[0004] However, when this type of glove knitting machine is in operation, its front and rear heads are in an "idle" state for half of each back-and-forth process and do not knit gloves. Therefore, in March 2022, the applicant Shi Xiaochuan published patent "CN114182422A" (reference document 1), which proposed a solution, namely, eliminating the head connection device and controlling the front and rear heads separately through a servo motor, so that the glove knitting machine can knit during the back-and-forth operation of the front and rear heads. The core functional technology claimed in the patent is as follows: [paragraph 0045 of the specification]

[0005] "First, the front and rear needle guide heads are independently driven by two servo motors (other common glove machines use a single motor to drive the front and rear needle guide heads). Of course, it is also possible to have one motor drive and a mechanical structure to switch between offset and parallel motion of the front and rear needle guide heads.

[0006] Second, each yarn feeder is also independently driven by an independent stepper motor or servo motor;

[0007] 3. The needle raising triangles of the front and rear needle guide heads can push the needles on the needle bed when moving in both directions, and adjust the range of the needle descent.

[0008] However, after research, the applicant believes that using the front servo motor and the rear servo motor to achieve differential operation and realize differential operation or synchronous reciprocating motion of the front guide needle head and the rear guide needle head requires high control accuracy of the two servo motors (switching between differential and synchronous is required), is difficult to debug, and is inconvenient to maintain.

[0009] Therefore, on August 24, 2023, an earlier patent for "A glove knitting process, application number 2023109982669" was applied for. Through the cooperation of multiple systems on two machine heads, double-sided knitting can be achieved under the synchronous operation of the machine heads.

[0010] After a period of production trials, the applicant further improved the triangle layout and structure in each system based on the knitting process, and developed a double-head knitting process for a glove machine, which has higher knitting efficiency.

[0011] Summary of the Invention

[0012] In order to achieve the above purpose, the technical solution of the present invention is as follows

[0013] A double-head knitting process for a glove machine is based on a first head and a second head that maintain synchronous operation, wherein the first head is provided with a first cam base plate, and the second head is provided with a second cam base plate; when knitting the current row, the last several needles on the first cam base plate have not yet completed knitting, while the needles on the second cam base plate have already started to cast on; or the last several needles on the second cam base plate have not yet completed knitting, while the needles on the first cam base plate have already started to cast on.

[0014] The glove knitting machine does not use a needle selector but a needle selection roller. Therefore, the cam plate here refers to the cam plate in the knitting area rather than the needle selection area. The "current row" means that the glove has a cylindrical structure, and one loop on the glove is a knitting row. The needle bed is provided with a row of knitting needles. Knitting is completed only when all the knitting needles involved are lifted and lowered. In the previous double-sided knitting, the needles of one cam plate must completely complete knitting before the needles of the other cam plate can start knitting. For details, please refer to the embodiment and the attached explanation.

[0015] Furthermore, the first triangular base plate on the first head includes a first system and a second system, and the second triangular base plate on the second head includes a third system and a fourth system. The first system and the third system are arranged front to back relative to each other, and the second system and the fourth system are arranged front to back relative to each other.

[0016] When knitting both sides of gloves at the same time, according to the different movement directions of the machine head:

[0017] Or the second system and the third system participate in weaving,

[0018] Or the first system and the fourth system participate in weaving.

[0019] This knitting method is consistent with the knitting method of the prior application, and improvements have been made in the needle starting timing of the front and rear heads.

[0020] Furthermore, two first needle-raising triangles are arranged on the first triangle base plate, and the two first needle-raising triangles are arranged in a staggered manner, in an overlapping manner, or in a staggered and overlapping manner. The staggered and overlapping arrangement of the first needle-raising triangles makes the needle-raising more compact during double-sided knitting.

[0021] During normal knitting in the prior patent, the two casting triangles on the first triangle base plate are far apart, and two elastic triangles are arranged between them. When the knitting needles cast on the two opposite needle beds in turn, the knitting needles on one side will start to cast on after the knitting needles on the other side have completed knitting. The knitting needles need to be lifted by the casting triangle before they can participate in knitting, and they need to pass through the upper Zhongshan triangle and the lower Zhongshan triangle, and pass through the lower end of the density triangle (the lower the density triangle, the larger the loop knitted) to complete the knitting of one loop. Moreover, since the casting bevel angles of the upper and lower Zhongshan triangles cannot be too vertical, the widths of the two triangles cannot be changed at will.

[0022] Therefore, in the present invention, when the first needle casting triangle and the second needle casting triangle are arranged in an staggered and overlapping manner, the knitting needles on the needle bed on one side have not yet completed knitting (that is, have not reached the lower end of the density triangle), while the knitting needles on the needle bed on the other side have already started casting, thereby improving the knitting efficiency; that is, the knitting efficiency of the technical solution of the present invention is higher than the previous double-sided knitting efficiency and higher than the knitting efficiency of the existing glove machine.

[0023] Furthermore, a swing density cam is provided on the second cam bottom plate, and the swing density cam can swing left and right on the second cam bottom plate, and its swing amplitude corresponds to the two first needle raising cams on the first cam bottom plate.

[0024] The density triangle located in the middle on the previous second triangle base plate only has the function of sliding up and down to adjust the coil density, so that the density triangle on the second triangle base plate has a swing function. While ensuring the function of the density triangle, it matches the "more compact knitting needle casting" between the first needle casting triangle and the second needle casting triangle on the first triangle base plate.

[0025] Furthermore, an auxiliary density triangle is provided on each side of the swing density triangle, and the auxiliary density triangle rises and falls in conjunction with the swing density triangle.

[0026] Depending on the direction of the knitting needle, when the knitting needle moves downward along one side of the swinging density triangle, it pushes the swinging density triangle at the same time, and moves through the lower end of the swinging density triangle and the lower end of the auxiliary density triangle to achieve control of the knitting coil density; the auxiliary density triangle and the swinging density triangle are linked to reduce the number of control units.

[0027] Furthermore, a second left density triangle and a second right density triangle are provided on the second triangle bottom plate, and the second left density triangle and the second right density triangle are adjacent to each other.

[0028] The reason for setting up this technical solution is the same as that for the swinging density triangle. The previous density triangle has ample space for the knitting needle stroke. When it is set in the middle, it can adapt to the left or right row of knitting needles. After the modification, the lower end of the density triangle needs to act on the right side when the knitting needles move from left to right, and the lower end of the density triangle needs to act on the left side when the knitting needles move from right to left. Therefore, the original function of the density triangle is guaranteed by setting up a separate density triangle or swinging the density triangle.

[0029] Furthermore, a limiting triangle is set above the swinging density triangle or the second left density triangle and the second right density triangle, and the slopes on both sides of the limiting triangle are consistent with the slopes on both sides of the swinging density triangle or the slopes of the sides of the second left density triangle and the second right density triangle.

[0030] A complete combination knitting needle has multiple needle butts. The oblique side of the limiting triangle is used to limit one of the needle butts of the knitting needle, so that the needle butt relatively located below is not easy to "hook" when moving along the density triangle.

[0031] Furthermore, a first rubber triangle is provided on each side of the first triangular base plate, and a second rubber triangle is provided on each side of the second triangular base plate, and the setting directions of the needle raising of the first rubber triangle and the needle raising of the second rubber triangle are opposite; when the rubber is knitted, depending on the different running directions of the machine head, either the rubber triangles of the first system or the fourth system participate in the knitting, or the rubber triangles of the second system or the third system participate in the knitting.

[0032] In the prior application, the two rubber triangles of the first triangular base plate (the rubber triangle is not a necessary technical feature for glove knitting, it is only used for the rubber knitting function) are set between the two cast-on triangles, and the two rubber triangles of the second triangular base plate are set on both sides; because in this case, the two cast-on triangles on the first triangular base plate are staggered, the rubber triangles are also set on both sides, and by setting their directions to be different from the direction of the rubber triangles on the second triangular base plate, the staggered work is achieved by the different left and right movement directions of the machine head, so that the rubber triangles on the two base plates do not conflict.

[0033] Furthermore, a first pressing cam is provided on the left side of the first triangular bottom plate, a first left density cam is provided on the right side of the first pressing cam, and a needle passage is left between the first elastic cam on the left side of the first triangular bottom plate and the first pressing cam and the first left density cam.

[0034] The needle channel is used for crocheting the elastic thread when the needle is knitting elastic.

[0035] Furthermore, a switching cam is provided above the two first casting cams. When seam knitting is performed, the switching cam extends from the first cam bottom plate.

[0036] The switching cam can move forward and backward relative to the cam base plate, and the switching cam is extended only when the seam is knitted.

[0037] After adopting the above scheme, the present invention has the following advantages compared with the prior art:

[0038] By redesigning the main functional cam in the double-sided knitting system, the needles on the front and rear needle beds are more compact during knitting, which directly improves knitting efficiency. At the same time, the size of the cam base is reduced, so that the size of the entire glove machine can also be reduced accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0060] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0061] In this invention, the knitting principle of the cams on the head cam base plate is the same as that of conventional single-jersey glove knitting machines or prior applications. The cast-on cam and elastic cam can move back and forth relative to the cam base plate; the density cam moves up and down relative to the cam base plate to adjust the stitch size; and the upper and lower mid-mount cams are fixed. The needle rows are mounted on fixed front and rear needle beds, and the knitting needles are lifted and engaged in knitting by moving the head left and right.

[0062] In the prior application "2023109982669", as shown in Figures 1 and 2, the front and rear triangular bottom plates of the front and rear heads are divided into four weaving systems: the first, second, third, and fourth systems, with the middle dotted line as the boundary. Among them, due to the top view of the unfolding angle, the front head is actually "upside down" in Figure 1. See Figure 2 when looking at the front head from the rear head:

[0063] When performing double-sided normal (complete) knitting, depending on the different movement directions of the machine heads: either the second system and the third system participate in the knitting, or the first system and the fourth system participate in the knitting, the butts of the knitting needles move along the needle casting triangles involved in the work, through their respective upper Zhongshan triangles 005 and lower Zhongshan triangles 006; from the perspective of the side of the needle bed, that is, when the system on the machine head on one side is completely knitted, the system on the machine head on the other side starts to knit, as shown in Figure 3.

[0064] At the same time, in the prior application, a first elastic triangle 003 and a second elastic triangle 004 are provided between the first casting triangle 001 and the second casting triangle 002, and the elastic triangles are extended to participate in the work only when elastic knitting is required.

[0065] After adopting the design concept of the present invention, the system on the head on one side can start knitting while the system on the head on the other side has not yet completed knitting, as shown in FIG4 .

[0066] As shown in Figures 15 and 16, the ellipse in the figure indicates the "current row" of the glove to be knitted (which can be understood as a circle along the palm, etc.), and the upper and lower boxes are the four knitting systems on the two triangular base plates. In the prior application, as shown in Figure 15, the head of the machine runs from left to right. The first and fourth systems need to completely leave the knitting area of ​​the "current row" before the third and second systems start to cast on, and the head of the machine turns to prepare for running from right to left. However, as shown in Figure 16, the present invention can be carried out without the first and fourth systems completely leaving the knitting area of ​​the "current row", and the third and second systems can cast on.

[0067] The following is explained in detail with specific examples:

[0068] A double-head knitting process for a glove machine comprises a first cam base plate 1 and a second cam base plate 2. Both cam base plates can be used for a front needle bed or a rear needle bed.

[0069] The first triangular base plate 1 takes the angle of Figure 5 as an example:

[0070] The first triangle base plate 1 includes a first upper Zhongshan triangle 101, a first lower Zhongshan triangle (111, 112), a first needle raising triangle (121, 122), a first density triangle (131, 132), a first elastic triangle (141, 142), and a first pressing triangle 15, wherein the first upper Zhongshan triangle 101 is located at the upper middle part of the first triangle base plate 1, and a first lower Zhongshan triangle (111, 112) is provided on the left and right sides below the first upper Zhongshan triangle 101. The gap between the first upper Zhongshan triangle 101 and the first lower Zhongshan triangle (111, 112) is the needle trajectory of the knitting needle during normal knitting. Between the bottoms of the two first lower Zhongshan triangles (111, 112) are two partially staggered first needle raising triangles (121, 122). In Figure 5, one end of the needle raising bevel of the first needle raising triangle 122 on the left side extends into the needle raising bevel of the first needle raising triangle 121 on the right side to form an interlaced pattern, and also form a partial overlap in space (refer to Figure 2 for the two complete needle raising triangles in the prior patent). A first density triangle (131, 132) is provided on each side of the first upper Zhongshan triangle 101, and a first elastic triangle (141, 142) is provided on each side of the first triangle base 1. The difference is that the first needle pressing triangle 15 is located above the first elastic triangle 142 on the left side, and the needle guard triangle 16 is located above the first elastic triangle 141 on the right side.

[0071] A switching cam 17 is further provided above the two first needle raising cams, and the switching cam 17 can move forward and backward relative to the first cam bottom plate 1.

[0072] The second triangular base plate 2 takes the angle of Figure 6 as an example:

[0073] The second triangular base plate 2 includes a second upper Zhongshan triangle (201, 202), a second lower Zhongshan triangle (211, 212), a second needle raising triangle (221, 222), a second density triangle, a second rubber triangle (241, 242), and a second pressing triangle 25. In this embodiment, the second density triangle is a swinging density triangle 23, which is located in the middle of the second triangular base plate 2. An auxiliary density triangle (231, 232) is provided on each side of the swinging density triangle 23. The auxiliary density triangle is linked to the swinging density triangle 23 through the connecting seat at the rear of the second triangular base plate 2, so that the auxiliary density triangle and the swinging density triangle 23 are synchronously lifted and lowered, and the lower end of the swinging density triangle 23 moves back and forth close to the auxiliary density triangles (231, 232) on the left and right sides when swinging.

[0074] On both sides of the pivot point of the swing density triangle 23 are the second upper Zhongshan triangles (201, 202), and below each second upper Zhongshan triangle is a corresponding second lower Zhongshan triangle (211, 212), and next to the side of the second lower Zhongshan triangle is the second needle raising triangle (221, 222), and relatively outside the second needle raising triangle is the second rubber triangle (241, 242), which is different from the rubber triangle in the prior application in Figure 1. The needle raising direction of the second rubber triangle here is opposite to the needle raising direction of the first rubber triangle in Figure 5, that is, in order to speed up the needle raising, the two first needle raising triangles are staggered, so that the rubber triangle of the first triangle base plate 1 can only be set to the left and right sides. Therefore, in order to achieve normal operation of rubber knitting, the above settings are made, and the specific needle trajectory of rubber knitting is described below.

[0075] As shown in Figure 7, the density triangle on the second triangular base plate 2 can also replace the swing density triangle 23 with the second left density triangle 233 and the second right density triangle 234. The second left density triangle 233 and the second right density triangle 234 are arranged adjacent to each other. The knitting needles shown in the figure move from right to left (that is, the triangular base plate moves from left to right).

[0076] The previous density triangle has ample space for the knitting needle stroke. When it is set in the middle, it can adapt to both the left and right rows of knitting needles. After the modification, the setting method of the density triangle in Figures 6 and 7 is to correspond to the compact setting of the needle-starting triangle on the first triangle base plate 1. When the knitting needle moves from left to right, the lower end of the density triangle needs to act on the right side, and when the knitting needle moves from right to left, the lower end of the density triangle needs to act on the left side. Therefore, the original function is guaranteed by setting up a separate density triangle or swinging the density triangle.

[0077] At the same time, a limiting triangle 26 is provided above the density triangle in the technical solutions of Figures 6 and 7. The slopes on both sides of the limiting triangle 26 are consistent with the slopes of the bevel of the needle starter of the density triangle below. The limiting triangle 26 is used to assist the knitting needle in moving the needle when the density triangle is in motion, especially when the density triangle is a swinging density triangle 23, the needle butt above the knitting needle moves along the limiting triangle 26 to reduce the burden on the needle butt below the knitting needle when pushing the density triangle to swing.

[0078] When double-sided normal weaving:

[0079] As shown in Figures 8 and 9, in order to show the relative position relationship between the first triangular base plate 1 and the second triangular base plate 2 during weaving, the angle of the first triangular base plate 1 is opposite to that of Figure 5. What is shown here is the angle from the back to the front of the first triangular base plate 1. With reference to Figure 1, the left and right sides of the first triangular base plate 1 are divided into the first system and the second system, and the left and right sides of the second triangular base plate 2 are divided into the third system and the fourth system.

[0080] Taking the angle of Figure 8 as an example, the machine head moves to the left and the knitting needles move to the right. The second needle-casting triangle 221 on the left side of the second triangle base plate 2 participates in weaving, and passes between the second upper Zhongshan triangle 201 and the second lower Zhongshan triangle 211, pushing the swing density triangle 23 to swing right, and the knitting needles are about to complete the coil weaving. At this time, the knitting needles of the first triangle base plate 1 have been cast on and participated in weaving under the action of the first needle-casting triangle 122 of the second system (corresponding to Figure 4), and then pass between the first upper Zhongshan triangle 101 and the first lower Zhongshan triangle 112 on the right, and complete the coil weaving through the lower end of the first density triangle 132 on the right.

[0081] Taking the angle of Figure 9 as an example, the machine head moves to the right and the knitting needles move to the left. The second casting triangle 222 on the right side of the second triangle base plate 2 participates in weaving, and passes between the second upper Zhongshan triangle 202 and the second lower Zhongshan triangle 212, pushing the swing density triangle 23 to swing left (at this time, the dotted line corresponding to the bottom of the swing density triangle in Figure 9 is already at the cast-on bevel of the first cast-on triangle 121, which is consistent with Figure 8); Correspondingly, the knitting needles of the first triangle base plate 1 participate in weaving under the action of the first cast-on triangle 121 of the first system, and then pass between the first upper Zhongshan triangle 101 and the first lower Zhongshan triangle 111 on the left, and complete the coil weaving through the lower end of the first density triangle 131 on the left.

[0082] That is, in the case of double-sided knitting, through the cooperation of the cam bottom plates on the front and rear machine heads, the knitting needles on the other side have started knitting before the knitting needles are completely knitted. That is, when the third system is knitting, the knitting needles are not at the lowest point of the swing density triangle 23, but the knitting needles of the second system are already casting; or when the fourth system is knitting, the knitting needles are not at the lowest point of the swing density triangle 23, but the knitting needles of the first system are already casting.

[0083] When single-sided (i.e. single system) knitting:

[0084] The present invention can also be used for single-sided knitting, as shown in Figures 10 and 11, that is, when the machine head moves to the left or right, only one system is working.

[0085] When seam knitting:

[0086] Taking the angle of FIG. 12 as an example, the seam cam 18 and the switching cam 17 extend together from the first cam base plate 1 , and the second system and the fourth system work simultaneously.

[0087] When braiding elastic bands:

[0088] 13 as an example, the machine head moves left, the needles move right, the second cam base plate 2 is knitted in the third system, and the elastic cam 242 of the fourth system is extended; the first cam base plate 1 is knitted in the first system, and the elastic cam 141 is extended and knitted in the second system.

[0089] 14 as an example, the machine head moves right, the needles move left, the second cam base plate 2 is knitted in the fourth system, and the elastic cam of the third system extends; the first cam base plate 1 and the elastic cam of the second system extend 142 and are knitted in the first system.

[0090] The above are only specific embodiments of the present invention. At the same time, all words such as "upper, lower, left, right, middle" involved in the present invention are for reference only and are not absolute limitations. Any non-substantial changes made using the present invention shall be deemed as an infringement of the protection scope of the present invention.
