Description

Knitting goods having hall formed by continuous process

The present invention relates to knitted fabrics such as stockings and socks, and specifically, to a knitted fabric in which holes and finishing structures are formed at desired positions during the knitting process.

In general, knitted fabrics are manufactured by connecting loops continuously through a reciprocating motion of a needle, and such knitted fabrics include stockings, socks, sweaters, vests, and shawls.

Knitting machines for manufacturing knitted fabrics can be largely divided into circular knitting machines and flat knitting machines, among which circular knitting machines are widely used in the manufacture of stockings, socks, and the like, and as shown in Fig. 1, a plurality of insertion grooves along the vertical direction ( 11) is formed in a cylindrical cylinder 10, a plurality of needles 30 inserted into the plurality of insertion grooves 11, respectively, and a jack inserted into the lower portion of the needle 30 in each insertion groove 11 ( 40).

Although not shown in the drawing, a feeder for supplying yarn to the needle 30 is installed on the upper portion of the cylinder 10, and in general, four feeders are arranged at intervals of about 90 degrees.

Each needle 30 includes a hook 32 formed on the upper end to hang the thread supplied from the feeder, a latch rotatably coupled to the lower portion of the hook 32 (33 in Fig. 2), and a cylinder 10 at the lower end. It includes a butt (34) protruding to the outside of the, in general, approximately 400 needles 30 are used in the circular knitting machine for stocking manufacturing.

A cam block (not shown in the drawing) is installed on the outside of the cylinder 10 so as to be able to move backwards and forwards, and this cam block is a needle cam that provides a path to rise while the butt 34 of the needle 30 comes into contact with it. It may include a stitch cam and the like to provide a path to descend and.

Therefore, when the cylinder 10 is rotated, the plurality of needles 30 mounted on the cylinder 10 move upward and downward along the needle cam and stitch cam of the cam block in the process of sequentially passing the lower part of each feeder, In this process, each needle 30 makes a new loop using the thread supplied from the feeder. For example, if there are 4 feeders, each needle 30 makes 4 new loops while the cylinder rotates once.

The jaw 40 is installed under the needle 30 to lift and lower the needle 30, and the cam butt 42, the control butt 44, and the butt 42 and 44 protrude outward respectively. It may include a spring 46 protruding to the opposite side.

The cam butt 42 is a part that moves along the ascending path or the descending path provided by the jack lifting cam (not shown in the drawing), and the control butt 44 is a matrix that controls the operation of the jack 40 (in the drawing It is the part where the control protrusion of (not shown) contacts. The matrix is installed so as to selectively press the control butt 44 of all the jacks 40.

The operation of the Jacques 40 can be individually controlled by a matrix, and therefore, the Jacques 40 is mainly used when a plurality of needles 30 are operated in a complex pattern to form a pattern or pattern on a knitted fabric.

In a general knitting section, it is common to raise and lower the needle 30 with only a cam block, but unlike this, the jac 42 is raised or lowered along the joc elevating cam without using a cam block or the jac 42 is elevated through matrix control. You can also proceed with knitting while ordering. In the case of forming a pattern, pattern, etc., in many cases, the upper needle 30 is lifted or lowered by individually controlling the jaws 42 of the corresponding section through matrix control.

Looking at a general knitting method, as shown in FIG. 2, when the needle 30 is raised while the old loop 62 is formed, the latch 33 is opened downward by the old loop 62. Subsequently, when the needle 30 is lowered, the thread 60 is caught on the hook 32, and if the needle 30 is continuously lowered, the old loop 62 pushes the latch 33 upwards and closes the needle 30 Upon exit, a new loop 64 is formed. The entire needle 30 repeats this process and the loops are continuously connected to perform knitting, and the knitted fabric descends downward through the inside of the cylinder 10 and is wound on a predetermined take-up roller.

However, since a number of loops are connected in a row in this way, the knitted fabric has a disadvantage that it is easily loosened when the loop is broken in the middle. In particular, tights that are knitted with very thin threads often exhibit this loosening phenomenon.

On the other hand, in recent years, in order to increase the convenience of stockings that are inconvenient to wear and take off, there are increasing cases of forming holes for various purposes in stockings. For example, as shown in Patent Document 1, there are cases where a hole for toilet or ventilation is formed in the panty part of the stockings, and a hole for ventilation is formed in the foot of the stockings or a hole through which the foot can be removed is also formed. have.

However, in order to form such a hole in a knitted stocking, a separate sewing operation (e.g., overlock) must be additionally performed to prevent loosening after cutting the part, so productivity is lowered and product unit cost is inevitable. there is a problem. Since this problem may occur not only in stockings but also in other types of knitted fabrics, there is a need to prepare a plan for improvement.

Registered Utility Model Publication No. 20-0365098 (Announcement date: 2004.10.15)

The present invention is to solve this problem, and an object thereof is to provide a knitted fabric capable of easily forming a hole without a separate additional sewing operation.

In order to achieve the above object, an aspect of the present invention, the first finishing structure formed in connection with the general knitting area; A hole formed on the top of the first finished tissue; It is formed on the upper part of the hole and includes a second finishing structure connected to the general knitting area at an upper end, and the first finishing structure is folded down and joined to the lower end of the first finished tissue, and the second finishing structure is at the bottom It is folded up and coupled to an upper end of the second finishing structure, and the first finishing structure, the hole and the second finishing structure are formed in a continuous process on the same knitting machine.

The knitted fabric according to the present invention may include a third finishing structure formed on both sides of the hole in the same course as the entire course of the first finishing structure, the hole, and the second finishing structure.

According to the present invention, it is possible to easily form a hole of a desired size at a desired position while knitting a knitted fabric, and since there is no need to perform additional cutting and sewing operations after completing knitting as in the prior art, cost reduction and productivity improvement can be expected. I can. Furthermore, since it is possible to easily form a hole of a desired size at any position of the knitted fabric, various functions and convenience can be given to knitted fabrics such as stockings and socks, and through this, it is expected to improve customer satisfaction and increase demand.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

The present invention relates to a knitting method for forming a hole together with a finishing structure at a desired location during a knitting process. First, since the drawings attached to the present specification are simply illustrated for convenience of description and understanding, it should be noted in advance that the scope of the present invention is not limited thereto.

3 and 4 are photographs and conceptual diagrams showing holes 102 formed in knitted fabrics (eg, stockings) by a knitting method according to an embodiment of the present invention, respectively.

As shown in the drawing, according to an embodiment of the present invention, a hole forming region 100 is set in the middle of a general knitting region 200 in which knitting is performed in a general manner, and a hole 102 is formed in the hole forming region 100. And the finishing structure around the hole (110, 120, 130) are included. In addition, the knitting process of the general knitting area 200 and the knitting process of the hole forming area 100 are continuously performed without interruption.

Looking at the hole formation region 100 in more detail, the first and second finishing structures 110 and 120 respectively formed on the lower and upper portions of the hole 102 to prevent loosening, and the first and second 2 It is formed on both side ends of the finishing structures (110, 120) and includes a third finishing structure (130) to prevent all loosening at both side ends of the hole (102).

The location or use of the hole 102 is not particularly limited. For example, it may be formed to ventilate the soles of the feet such as stockings or to remove the feet, or may be formed in the panty of stockings for toilet use. In addition, it may be formed to fit the arm in a position adjacent to the band portion at the top of the full-body stocking, and may be formed for various purposes in various other positions.

As shown in the flow chart of FIG. 5, the hole forming method according to the embodiment of the present invention includes the step of performing a general knitting (ST11), and a first finishing structure 110 below the position where the hole 102 is to be formed. While forming, the step of forming the third finishing structure 130 on both sides of the first finishing structure 110 (ST12), forming the hole 102 at the set position (ST13), and the hole 102 While forming the second finishing structure 120 on the upper part of the), the third finishing structure 130 is continuously formed on both sides of the second finishing structure 120 to complete the step (ST14), and general knitting is performed again. And a step (ST15).

In addition, the knitting method according to the embodiment of the present invention includes a cylinder 10, a plurality of needles 30 and a jack 40 inserted into the outer surface of the cylinder 110, as described above, at the top of the cylinder 110. It can be made through a circular knitting machine including a plurality of feeders to feed the yarn. However, since the type of knitting machine is not necessarily limited to the circular knitting machine, it is also possible to implement the method according to the present invention using another type of knitting machine.

Hereinafter, a process of forming the hole 102 in a knitted fabric according to an embodiment of the present invention will be described in detail with reference to the flowchart and reference diagram of FIG. 5.

First, knitting for the general knitting area 200 is performed in a general manner. In this case, as the cylinder 10 rotates, as shown in the conceptual diagram of FIG. 6, all the needles 30 perform ascending movements and lifting movements in the lower portions of the first to fourth feeders 1F, 2F, 3F, 4F. As you repeat, you form a loop. At this time, the needle 30 is generally raised and lowered along the needle cam 70 and the stitch cam 80 constituting the cam block, but by raising and lowering the jak 40 in a state in which the cam block is retracted, the upper portion of the jac 40 The needle 30 may be raised or lowered.

On the other hand, when knitting for the general knitting area 200 is performed, yarn is supplied from all of the first to fourth feeders 1F, 2F, 3F, 4F, and thus all needles 10 are supplied every time the cylinder 10 rotates. ) Forms 4 loops. (ST 11)

As described above, when a course corresponding to the hole forming region 100 is reached, knitting of the first finishing structure 110 is started and the third finishing structure ( 130) begin to knit.

In this case, it is preferable to raise and lower each needle 30 by the jaws 40 individually controlled by the matrix in a state in which the cam block is retracted. This is because the finishing structures 110, 120 and 130 require more complex needle control than general knitting.

9 and 10 are a conceptual diagram and a knitting state diagram showing a process in which knitting is performed by a knitting method according to an embodiment of the present invention, respectively. For reference, in FIG. 9, one loop formed during knitting is indicated by one circle, and thus, only one circle is displayed over several courses, meaning that the first course and the last course of the corresponding section are grouped into one loop.

According to the drawing, 54 needles 30 are used for knitting the hole forming region 100, of which 26 needles (15 to 40 needles indicated at the bottom of the drawing) are formed of the first and second finishing structures 110 and 120 Used in, each of the 14 needles (1 to 14 needles, 41 to 54 needles) on both sides is used to form the third finishing structure 130 on both sides of the first and second finishing structures (110.120).

That is, in the general knitting area 200, for example, knitting is performed in the usual manner by 400 needles 30, and when it reaches the course corresponding to the hole forming area 100, the finishing structure ( While 110, 120, 130 and holes 102 are formed, knitting is performed in a conventional manner by the remaining 346 needles outside of the hole forming region 100.

However, the number of needles 30 used for knitting the hole forming region 100 is not limited to that shown in the drawing, and may vary as much according to the width of the hole 102 or the finishing structures 110, 120, and 130.

On the other hand, in the embodiment of the present invention, when the hole forming region 100 reaches the course to be knitted, as shown in the conceptual diagram of FIG. 7, for example, the first feeder 1F is stopped supplying the yarn and the first feeder is In the lower part of (1F), the entire needle 30 is controlled so that it does not rise. Accordingly, the entire needle 30 passes through the lower portion of the first feeder 1F in a lowered state by hooking the thread supplied from the fourth feeder 4F to the hook.

Therefore, when knitting for the hole-forming region 100 starts, the first finishing structure 110 and the third on both sides by using the threads provided from the three feeders 2F, 3F, 4F excluding the first feeder 1F. Knitting of the finishing tissue 130 is made. Also, in the general knitting area 200 outside of the hole forming area 100, conventional knitting is performed using threads provided from the three feeders 2F, 3F, and 4F. (ST12)

In this way, when knitting for the hole forming region 100 is in progress and reaches the course corresponding to the hole 102 position, the first finishing structure 110 is completed, while 15 to 40 needles are threaded as shown in FIG. It is raised and lowered in the lower portion of the first feeder 1F that is not supplied.

As described above, when reaching the hole forming region 100, all the needles 30 are controlled so that they do not rise from the bottom of the first feeder 1F to which the thread is not supplied, and thus all the needles 30 The thread supplied in 4F) is hooked on the hook and passed through the lower part of the first feeder 1F in a lowered state.

Therefore, if the thread supplied from the fourth feeder 4F is hooked on the hook and the 15 to 40 needles in the lowered state are raised and lowered from the lower part of the first feeder 1F where the thread is not supplied, only the threads that were caught on these needles are After exiting, the 15 to 40 needles become empty without being supplied with thread. In this case, the 15 to 40 needles are completely separated from the loop of the first finishing structure 110, and thus, a hole 102 is formed on the top of the first finishing structure.

Meanwhile, while the hole 102 is formed in this manner, knitting for the third finishing structure 130 continues on both sides of the first finishing structure 110 and the hole 102. (ST 13)

After the hole 102 is formed in the manner described above, the second finishing structure 120 must be formed on the top of the hole 102. That is, the empty 15 to 40 needles are supplied with yarn from the second feeder 2F and begin to form a new loop for the second finishing structure 120. At the same time, on both sides of the second finishing organization 120, the knitting of the third finishing organization 120, which was previously in progress, continues. Even in this case, in the general knitting area 200 outside the hole forming area 100, conventional knitting continues using yarns provided from the three feeders 2F, 3F, and 4F. (ST14)

During the knitting of the second finishing tissue 120 and the third finishing tissue 130, when the hole forming region 100 reaches the end of the course, the second finishing tissue 120 and the third By completing the finishing structure 130, the process for the hole forming region 100 is completed. Then, as shown in Fig. 6, the yarn supply to the first feeder 1F is resumed and the needles are raised and lowered from the lower portions of all the feeders 1F, 2F, 3F, and 4F, thereby continuing normal knitting. (ST15)

Hereinafter, a specific method of forming the first to third finishing structures 110, 120, and 130 will be described.

As shown in Figs. 9 and 10, the first finishing structure 110 is knitted by, for example, 26 needles (15 to 40 needles), in which the entire course is divided into several sections and knitted in different ways. It is desirable.

In the embodiment of the present invention, the entire course is divided into three sections. For example, the first to third courses of the hole forming area 100 are set as the first section, the fourth course is the second section, Courses 5 to 14 were set as the third section.

However, since this is only an example, the number of courses may vary depending on the size of the finishing organization 110, and the number of sections belonging to this may vary.

Referring to the drawings, in the first section (courses 1 to 3), each needle 30 may alternately form three loops and one loop. That is, the 15 needles corresponding to the first needle of the first finishing structure 110 form three loops, the 16 needles form one loop by tying the first to third courses together, and the 17 needles form three loops. And 18 needles can knit the first section in an order of forming one loop by tying the first to third courses into one.

The first section is a section adjacent to the general knitting area 200 at the bottom of the first finished tissue 110, and when knitting in this manner, the structure becomes dense, so that it is not easily loosened, while the general knitting area 200 at the bottom Strengthens the bond with the family. In addition, it may be more firmly bound to the upper end of the first finishing tissue 110 that is folded downward afterwards.

The second section (4 course) is a part connecting the first section and the third section, and the drawings show that all of the needles (15 to 40 needles) form only one course, but the second section is not limited thereto. The number of courses constituting the section may be two or more.

The third section (courses 5 to 14) is a section in which the upper end of the first finishing tissue 100 is knitted so that it can be folded downward, and therefore, must have a sufficient length to be folded. For example, it is desirable to knit more courses than the first section.

In an embodiment of the present invention, in the third section (course 5 to 14) of the first finishing structure 110, two adjacent needles form a pair and operate in the same manner. For example, 15 needles and 16 needles corresponding to the first and second needles each tie the 5th to 14th courses together to form one loop, and the 17 needles and 18 needles each form 10 loops according to the number of courses. And, the 19 needles and 20 needles each tie the 5th to 14th courses together to form one loop, and the 21 needles and 22 needles each form 10 loops according to the number of courses. To 14 courses).

When knitting in this way, a number of courses are tied into one loop by approximately half of the needles used to form the first finishing structure 110, and thus the upper end of the first finishing structure 110 is pulled downward and folded. It is bound to the organization of the second section (4 courses) and the first section (1 to 3 courses) below.

As shown in Figs. 9 and 10, the second finishing structure 120 is knitted in a symmetrical manner with the first finishing structure 110 at the top of the hole 102.

Therefore, even in the case of the second finishing organization 120, it is preferable to divide the entire course into three sections and knit each section in a different way. However, in the case of knitting the second finishing tissue 120 symmetrically with the first finishing tissue 110, the first course to the 10th course from the hole 102 are set as the first section, and the 11th course is the second section. And the 12th to 14th courses can be set as the third section.

The number of courses and sections is not particularly limited in the second finishing organization 120 as in the first finishing organization 110.

Referring to the drawings, knitting of the second finishing structure 120 is started by 26 needles (15 to 40 needles) that have descended to an empty state in the process of forming the hole 102.

The first section (courses 1 to 10) of the second finishing structure 120 is a section that is knitted so that the lower end can be folded upward, and therefore, must have a sufficient length to be folded.

According to an embodiment of the present invention, in the first section (courses 1 to 10) of the second finishing structure 120, two adjacent needles form a pair and operate in the same manner. For example, 15 needles and 16 needles corresponding to the first and second needles in the first section (1 to 10 courses) of the second finishing structure 120 bind the first to the tenth courses into one to form one loop , 17 needles and 18 needles each form 10 loops according to the number of courses, 19 needles and 20 needles each tie the first to tenth courses into one to form one loop, and the 21 needles and 22 needles each form a course sink The knitting of the first section (1 to 10 courses) is carried out in the order of forming 10 loops and so on.

When knitting in this way, a number of courses are tied into one loop by approximately half of the needles used to form the second finishing structure 120, and as a result, the lower end of the second finishing structure 120 is pulled upward and folded. It is bound to the organization of the second section (11 courses) and the third section (12 to 14 courses) above.

The second section (11 courses) of the second finishing structure 120 is a part that connects the first section (1 to 10 courses) and the third section (12 to 14 courses), and in the drawing, each needle (15 to 40 needles) All of these are shown to form only one course, but the number of courses constituting the second section may be two or more, since it is not limited thereto.

The third section (12 to 14 courses) of the second finishing structure 120 is a section adjacent to the upper general knitting area 200, and each needle 30 is formed by alternating 3 loops and 1 loop. I can. That is, 15 needles form 3 loops, 16 needles combine the 12th to 14th courses into one to form one loop, 17 needles form 3 loops, and 18 needles form 12th to 14th courses. The third section (12 to 14 courses) can be knitted in an order such as forming one loop by tying them together.

If the third section (12 to 14 courses) is knitted in this manner, the structure becomes dense and the yarn is not easily loosened, while the bonding strength with the upper general knitting area 200 is increased. In addition, the lower end of the second finishing tissue 110, which is later folded upward, serves to be firmly bound to the upper general knitting area 200.

Meanwhile, the third finishing tissue 130 located on both sides of the hole 102 starts knitting together with the first finishing tissue 110 on both sides of the first finishing tissue 110, and the first finishing tissue 110 After completion, the knitting is continued even when the hole 102 is formed, the knitting is continued while the second finishing structure 120 is in progress, and it is completed together when the knitting of the second finishing structure 120 is completed.

Looking specifically with reference to FIGS. 9 and 10, in an embodiment of the present invention, among the 54 needles 30 used for knitting the hole forming region 100 for the third finishing structure 130, the needle for hole formation ( 15 to 40 needles) each of 14 needles (1 to 14 needles, 41 to 54 needles) located on both sides of the needle.

Looking at the operation of the 1 to 14 needles, when knitting of the hole forming region 100 starts, the 1 needle, 5 needles and 9 needles form a loop every 29 courses, and 2 to 4 needles, 6 to 8 needles, 10 to 12 needles each tie the entire 1 to 29 courses together to form one loop, and the 13 needles and 14 needles form a loop for each course.

In addition, looking at the operation of the 41 to 54 needles, the 41 and 42 needles form a loop for each course, and the 43 to 45 needles, 47 to 49 needles, and 51 to 53 needles each tie 1 to 29 courses into one loop. And 46 needles, 50 needles and 54 needles form a loop every course.

In this way, the third finishing structure 130 has a plurality of sections that combine the first course and the last course of the hole forming region 100 with one loop, through which both sides of the first and second finishing structures 110 and 120 3 Since it is strongly tightened by the finishing structure 130, loosening around the hole 102 can be prevented.

In the above, preferred embodiments of the present invention have been described, but the present invention is not limited to the above-described embodiments and may be modified or modified in various forms.

As an example, in the embodiment of the present invention, a finishing structure (110, 120, 130) is formed around the hole 102, but the finishing structure (110, 120, 130) is to prevent loosening around the hole 102, thus achieving this purpose. It is possible to organize the finishing organization (110, 120, 130) in various ways within the range that can be. Therefore, the number of needles, knitting patterns, etc. for forming the finishing structures 110, 120, 130 are not limited to the above-described embodiments and may be modified in various ways in specific applications.

As another example, the knitting method according to the present invention is proposed to form holes and finishing structures in stockings, socks, etc. in a continuous process, but in other types of knitted fabrics such as sweaters, vests, shawls, tops, hats, underwear, etc. Naturally, it can also be applied to the case of forming the finishing structure at the same time.

As another example, in the above-described embodiment, a third finishing structure 130 for tightening the side ends of the first and second finishing structures 110 and 120 on both sides of the hole 102 is formed, but is relatively thick. When there is little risk of disconnection due to knitting with thread or by knitting with strong thread, the third finishing structure 130 may be omitted.

As another example, as described above, since the type of knitting machine for forming holes during knitting according to the method of the present invention is not limited, while manufacturing a knitted fabric using various knitting machines such as circular knitting machine and flat knitting machine, according to the present invention Through the method, the hole and the finished structure can be formed in a continuous process.

As described above, the present invention may be modified or modified in various forms, and it is natural that the modified or modified embodiments belong to the scope of the present invention if the technical idea of the present invention disclosed in the claims to be described later is included.
