Description

Technical Field

[0001] The present invention relates to the field of glove knitting machines, and in particular to a glove knitting process. 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, and the front and rear machine heads, needle selection rollers and front and rear needle beds work together 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] Similarly, in "CN115961419A" (Comparative Document 2) disclosed in April 2023 by Zhejiang Baixiang Technology Co., Ltd., technology almost identical to that in Comparative Document 1 was also adopted, and its purpose was also to improve the production efficiency of the glove machine.

[0009] 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.

[0010] Therefore, the inventor conducted further research and developed a glove knitting process, which resulted in the present invention. Summary of the Invention

[0011] The object of the present invention is to provide a glove knitting process, which improves the knitting efficiency by setting the cam system itself.

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

[0013] A glove knitting process, comprising

[0014] A first handpiece and a second handpiece that maintain synchronous operation, wherein the first handpiece includes a first system and a second system, and the second handpiece 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;

[0015] When knitting both sides of gloves at the same time, according to the different movement directions of the machine head:

[0016] Or the second system and the third system participate in weaving,

[0017] Or the first system and the fourth system participate in weaving.

[0018] The directions facing the needle bed of the glove machine when the user stands in front of the machine are generally referred to as the front and rear heads. The directions of right and left heads are also based on the front of the machine. The system mentioned in this technical solution refers to a number of cams (such as the cast-on cam, upper middle-mounted cam, lower middle-mounted cam, density cam, etc.) that can perform the most basic knitting functions when knitting gloves. That is, in both the prior art and Reference 1, one cam system corresponds to one head. In previous computerized glove machines, when two heads were in operation, the cam system on one head was always not in the knitting state, which is equivalent to "single-system knitting". It can be understood that the cylindrical portion of the glove is formed by looping. However, in Reference 1, when knitting the cylindrical portion of the glove, the front and rear heads are differentially driven, so that the "front and back" sides of the glove can be knitted simultaneously, and the yarn feeder is used to interweave the "front and back" sides. It can be understood that the front and back sides of the cylindrical portion of the glove are knitted simultaneously, thereby achieving the purpose of improving production efficiency.

[0019] In this process, two cam systems are respectively provided on the front and rear heads. Therefore, it is not necessary to use front and rear servo motors for differential control as in Comparative Document 1, and it is often necessary to switch back and forth between "differential" and "synchronous" operation. The present invention controls the action of the cams on each cam system (which can be simply understood as whether a cam system participates in knitting) through the synchronous movement of the two heads, thereby achieving the technical effects in Comparative Document 1 and avoiding the technical problems existing in Comparative Document 1. Among them, the functions and operation modes of each cam are consistent with the existing technology. The system participates in knitting or work, such as: the needle-casting cam moves back and forth relative to the base plate for needle-casting; the density cam moves up and down relative to the base plate for controlling the size of the gloves; the upper and lower Zhongshan cams are fixed to limit the needle trajectory, etc.

[0020] Furthermore, a plurality of yarn feeders are provided above the first head and the second head, and the yarns between the first head, the second head and the yarn feeders can be in an interwoven state during double-sided knitting of the double system.

[0021] The yarn feeder is arranged on the guide rail above the machine head and can slide left and right to supply thread to the knitting needles driven by the machine head and involved in knitting; when describing the yarn feeder, the comparative document 1 did not limit the position of the yarn feeder, but only mentioned that the front machine head cooperates with the yarn feeder No. 1 and the rear machine head cooperates with the yarn feeder No. 2, and when changing direction, the yarns are exchanged with each other [Comparative Document 1 Instructions 0037, 0038], but Comparative Document 1 did not disclose that when the yarn feeder cooperates with the machine head, the front machine head needs to cooperate with the yarn feeder relatively at the rear, and the rear machine head needs to cooperate with the yarn feeder relatively at the front, and the yarns of the two machine heads need to be "interwoven", otherwise two independent "fabrics" will be woven, and the number of yarn feeders arranged above the machine head is not fixed, as long as the number is greater than or equal to two.

[0022] Furthermore, when the second loom is knitting tucks, the loom moves right and the fourth system participates in knitting; when the loom moves left, all systems do not participate in knitting;

[0023] When the first loom is knitting, the loom moves right and all systems do not participate in knitting; when the loom moves left, the second system participates in knitting.

[0024] Tuck knitting is a technical term commonly used in this field, which means that the knitting needle runs along the middle height without passing between the upper and lower Zhongshan triangles (this is the trajectory of normal full-mesh knitting).

[0025] Furthermore, when cross-weaving, the systems in the front and rear adjacent positions participate in the weaving.

[0026] The cross-knitting here refers to the cross-knitting when the glove machine is knitting the finger seams, or knitting the palm after knitting the fingers (separating the fingers). Since the first and second heads are running synchronously, the front and rear adjacent systems here refer to the first and third systems or the second and fourth systems.

[0027] Furthermore, one of the four systems can be selected for weaving, that is, only one system is weaving when the two heads are running.

[0028] The present invention can also choose to use a single system for knitting like the existing glove knitting machines, without other systems participating.

[0029] Furthermore, the first system, the second system, the third system, and the fourth system all include an upper Zhongshan triangle, a lower Zhongshan triangle, and a needle-raising triangle; wherein the upper Zhongshan triangle of the first system and the upper Zhongshan triangle of the second system are an integrated structure.

[0030] Furthermore, both the first head and the second head are provided with rubber triangles, and when the first head and the second head move synchronously, double-sided rubber rib weaving can be performed through the rubber triangles.

[0031] The wrist part of the glove is also called the cuff. This part is usually closed with elastic, which is generally called elastic braiding in this field. The triangle that controls the ribbing in this part is called the elastic triangle, and elastic rubber thread is also used in conjunction with it.

[0032] Furthermore, the two density triangles of the first head are arranged on both sides of the upper Zhongshan triangle, and the density triangle of the second head is arranged between the two upper Zhongshan triangles.

[0033] Furthermore, the first head and the second head also include a pressing cam. The pressing cam of the first head and one of the density cams are an integrated structure, and the pressing cam of the second head is an independent cam.

[0034] The needle pressing triangle is used to assist the needle pressing to prevent the fingers from weaving into one another during knitting.

[0035] Furthermore, the first head and the second head are synchronously driven by the same driving device or by respective driving devices.

[0036] The existing machine head connecting device can be used to realize the synchronous operation of the two machine heads, and the synchronous operation of the front and rear machine heads can also be realized by using two driving devices.

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

[0038] The present invention does not need to control the two motors to switch between "differential speed" and "synchronous speed" frequently, but can be achieved through the synchronous operation of the front and rear heads, so the weaving process is more stable and controllable.

[0051] A triangulated system structure that can implement the method of the present invention is given below in conjunction with the accompanying drawings and specific embodiments.

[0052] Take the position of the user facing the glove machine needle bed when he is at the front of the glove machine (there is a discharge port on the front), and then look down from the needle bed needle mouth from top to bottom, and then expand to get the following Figure 1 The angle shown is the front nose Figure 1 In fact, it is "upside down". If you look from the rear nose to the front nose, you can see Figure 2 structure.

[0053] by Figure 1The dotted line in the middle is the boundary. The front head includes a first system 1 and a second system 2 set on the left and right. The rear head includes a third system 3 and a fourth system 4 set on the left and right. Each system includes various triangles, such as the upper Zhongshan triangle (11, 21, 31, 41), the lower Zhongshan triangle (12, 22, 32, 42), the needle triangle (13, 23, 33, 43), the rubber triangle (14, 24, 34, 44), the density triangle (15, 25, 35), etc. Among them, the Zhongshan triangle is a fixed structure, the needle triangle and the rubber triangle stretch back and forth relative to the bottom plate, and the density triangle moves up and down relative to the bottom plate. Its specific settings are as follows:

[0054] like Figure 2 As shown, the upper Zhongshan triangles (11, 21) of the first system 1 and the second system 2 of the front machine head are connected into an integrated structure, and lower Zhongshan triangles (12, 22) are respectively provided on the left and right sides below the upper Zhongshan triangles (11, 21), and a needle raising triangle (13, 23) is provided on the side of the lower Zhongshan triangle. There are two rubber triangles (14, 24) between the needle raising triangles, and density triangles (15, 25) are provided on the left and right sides of the upper Zhongshan triangle (11, 21), among which the density triangle 25 on the left side is also an integrated structure with the needle pressing triangle 26.

[0055] Correspondingly, Figure 1 It can be seen that the upper and lower Zhongshan triangles (11, 12, 21, 22) of the front machine head correspond to the upper Zhongshan triangle and lower Zhongshan triangle (31, 32, 41, 42) of the rear machine head. The difference is that the needle raising triangles (33, 43) of the rear machine head are relatively located on the outer side of the lower Zhongshan triangle (32, 42), opposite to the front machine head. This is determined by the direction of the machine head operation. For the same reason, the density triangle 35 of the rear machine head is set between the upper Zhongshan triangle (31, 41), and the elastic triangle (34, 44) is set on the relative outer side of the needle raising triangle (33, 43); at the same time, the needle pressing triangle 46 of the rear machine head is set independently, but its function is the same as the needle pressing triangle 26 of the front machine head. The difference is that the rear machine head is also provided with a seam triangle 37, which is used for seam knitting of the glove fingers. The seam is also mentioned in the comparative document 1 and will not be described in detail here.

[0056] A glove knitting process based on the front and rear heads is used for double-system double-sided knitting. Figure 3 、 4 For example, the angle:

[0057] like Figure 3As shown, the front and rear heads move to the right, the knitting needles "enter" from the right side (the needle bed is essentially stationary), the needle-casting triangle 43 of the fourth system 4 works, and the needle-casting triangle 13 of the first system 1 works: that is, the needle butts of the knitting needles of the rear head enter between the upper and lower Zhongshan triangles (41, 42) of the fourth system 4 through the needle-casting triangle on the right, and then descend along the density triangle 35, passing through the third system 3 without interacting with it; the knitting needles of the front head enter between the upper and lower Zhongshan triangles (11, 12) of the first system 1 through the needle-casting triangle 13 of the first system 1, and descend through the density triangle 15, that is, the front and rear heads simultaneously perform normal full-mesh knitting.

[0058] like Figure 4 As shown, the front and rear heads move to the left, the knitting needles "enter" from the left, the needle-casting triangle 33 of the third system 3 of the rear head works, and the needle-casting triangle 23 of the second system 2 of the front head works: that is, the needle butts of the knitting needles of the rear head enter between the upper and lower Zhongshan triangles (31, 32) of the third system 3 through the needle-casting triangle 33 on the left, and then descend along the density triangle 35, passing through the fourth system 4 without interacting with it; the knitting needles of the front head pass through the first system 1 without interacting with it, enter between the upper and lower Zhongshan triangles (21, 22) of the second system through the needle-casting triangle 23 of the second system 2, and descend through the density triangle 25, that is, the front and rear heads simultaneously perform normal full-mesh knitting.

[0059] Figure 3 、 Figure 4 The dotted line in the figure is a schematic diagram of the needle trajectory of the middle needle butt in the triangle system.

[0060] When performing the above-mentioned dual-system, double-sided knitting, the yarn feeders connected to the needles on each loom (i.e., the yarn required for knitting is provided by the yarn feeders) need only to ensure that the yarn feeder connected to the rear loom is relatively forward and the yarn feeder connected to the front loom is relatively backward, so that the yarns between the front and rear yarn feeders can be interwoven during knitting. (See also the description of yarn feeder supply in the comparative documents.)

[0061] Based on this process, a single-system conventional weaving (i.e., the existing weaving method) can also be used, that is, it is only necessary to start a single system for circulation when the machine head is running, which will not be described in detail here.

[0062] When the front and rear heads are knitting double-system double-sided rubber ribs, rubber triangles (24, 44) are added on the basis of the normal double-sided knitting of the double systems. That is, when the front and rear heads are moving right, the rubber triangles of the fourth system 4 are added to the work; when the front and rear heads are moving left, the rubber triangles of the front head are added to the work. For specific trajectory, refer to Figure 5 、 6 .

[0063] When the front and rear heads are knitting the seam, the front and rear heads move right, the first system 1 and the third system 3 participate in knitting, and the seam triangle 37 on the rear head participates in knitting; the front and rear heads move left, and the second system 2 participates in knitting; for specific trajectory reference Figure 7 、 8 .

[0064] When the rear head is knitting tuck, the head moves to the right, the fourth system 4 participates in knitting, and the needle butt passes through the needle-raising triangle 43 and does not pass between the upper and lower Zhongshan triangles (41, 42) (that is, the needle is also called the middle needle); the head moves to the left, and all systems do not participate; Figure 9 、 10 .

[0065] When the front head is performing tuck knitting, the head moves right and all systems do not participate in knitting; when the head moves left, the second system 2 participates in tuck knitting, and the butt of the knitting needle passes through the needle-raising triangle 23 and does not pass between the upper and lower Zhongshan triangles (21, 22) (that is, the knitting needle is also called the middle needle); Figure 11 、 12 .

[0066] The above are only specific embodiments described according to the process ideas 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 on the claims. Any non-substantial changes made using the present invention shall be deemed to infringe the scope of protection of the present invention.
