TECHNICAL FIELD OF THE INVENTION
The present invention relates to a circular knitting machine for knitting a knitted fabric by moving a sinker in and out of a reciprocating knitting needle, a stitch knitting method using a sock circular knitting machine, and a sock knitted by the method.
[0002]
[Prior art]
Conventionally, in a circular knitting machine or a sock circular knitting machine, the size (degree) of a stitch is changed by moving a stitch cam up and down to change a drawing amount of a knitting yarn by a knitting needle. FIG. 1 shows a sinker 10 and a knitting needle 30 according to a conventional technique. In FIG. 1, when the knitting needle 30 pulls the knitting yarn 60, the knitting yarn 60 is on the sinker top 15, and the knitting needle 30 is lowered to the bottom 51 of the stitch cam by the stitch cam 50 acting on the needle bat 31. The frequency at this time is determined by the distance (stitch length) Y1 between the sinker top line L1 and the bottom line L0. Although only a pair of sinkers and knitting needles are shown in FIG. 1 for simplicity, actually three to five knitting needles are simultaneously acted on by the bottom 51 of the stitch cam 50. The stitch is changed by moving the stitch cam 50 up and down and changing the descending distance of the knitting needle 30. Since the up and down of the stitch cam 50 is performed in units of several rotations of the knitting machine, the times in the same course are the same.
[0003]
A conventional technique for changing the stitch on a stitch basis is disclosed in, for example, Patent Document 1.
[0004]
[Patent Document 1]
JP-A-63-159551 (page 1, page 3, FIG. 1)
[0005]
The method disclosed in Patent Literature 1 is disclosed in claims 1. As described in `` To form stitches with different sizes by changing the drawing length of knitting needles, and by selecting knitting needles according to arbitrary regulations, to form patterns by the size of stitches '' There are features. However, this method requires a knitting mechanism in which individual knitting needles move independently of each other, and has a disadvantage that the mechanism is complicated. Further, this document does not disclose an actual knitting mechanism and is not feasible.
[0006]
Patent Literature 2 discloses a knitted fabric having a handle composed of portions having different loop lengths.
[0007]
[Patent Document 2]
JP 2001-207355 A (page 2, FIG. 6)
[0008]
The knitting method for a patterned knitted fabric disclosed in Patent Document 2 discloses a method of “changing the yarn feeding tension during knitting by a tension varying device, as described in“ Claim 2 ”of the claims. And forming a pattern consisting of portions having different loop lengths on the knitted fabric. " This method has a drawback that the stitch does not clearly change in units of stitches.
[0009]
[Problems to be solved by the invention]
In a circular knitting machine and a sock circular knitting machine, stitch knitting is performed by reciprocating motion of a knitting needle and moving a sinker in and out between the knitting needles. The stitch size is changed by moving the stitch cam up and down. In the sock circular knitting machine, the degree of change can be made for each part of the rubber part, the leg, and the foot part of the sock, but the degree of change cannot be made within the same course. For this reason, it is not possible to make an arbitrary change in the degree of distribution between the forefoot part and the hindfoot part of the sock. Similarly, it is not possible to make an appropriate magnitude distribution according to the shape of the foot.
[0010]
Multi-colored sock circular knitting machines often use wooly nylon yarn for the pattern part and cotton-acrylic blended yarn for the ground part, but the pattern part and the ground part have the same degree. I have. However, since the type of the knitting yarn is different between the pattern portion and the ground portion, it is necessary to originally change the stitch length. In a patterning method called a cut boss pattern in a sock circular knitting machine of a multicolored pattern, a yarn is cut between patterns and between a pattern and a ground portion. Therefore, there is a disadvantage that the cut yarn end comes out of the stitch. To prevent this, the stitch at the border between the patterns may be smaller than the stitch at the ground portion, but this cannot be done with a conventional sock circular knitting machine.
[0011]
The method disclosed in Patent Literature 1 describes that a knitting type in which knitting needles move independently and independently is used, as shown in page 3, upper right column, lines 5 to 11.
The knitting needles of current circular knitting machines and sock circular knitting machines reciprocate collectively in units of tens by the action of a stitch cam. In order to adopt the method disclosed in Patent Document 1, it is necessary to fundamentally change the shape of the knitting needle and the mechanism of operation by the stitch cam, and design and manufacture a new machine. Is also difficult.
[0012]
The present invention has been made in view of the above-mentioned conventional problems, and a first object of the present invention is to improve the function of a sock without changing a reciprocating mechanism of a knitting needle by a stitch cam of a current sock circular knitting machine. The degree of necessity is large, the degree of tightening of the foot is small, and the knitting of socks that matches the shape of the foot is required.
A second object of the present invention is to provide a multicolored pattern knitting machine, in which the stitches are changed between a pattern portion and a ground portion so that the pattern portion is more clearly displayed. For example, the stitch of the pattern portion is made smaller and the stitch is made denser, so that the pattern becomes clearer, and the stitch of the ground portion is made larger to secure the elongation of the knitted fabric.
A third object of the present invention is to provide a cut boss pattern of a multicolored pattern with a smaller stitch around the pattern than other knitted fabric portions, so that the cut yarn ends do not easily fall out of the stitch.
A fourth object of the present invention is to provide a synergistic effect of the knitting structure effect and the stitch effect by combining the change in the knitting structure and the change in the stitch. For example, when a tuck knitting structure is put into a knitted fabric, the stitch knitting portion is made larger, and the stitch knitting portion is made smaller, so that the tuck knitting portion can be made larger.
[0013]
[Means for Solving the Problems]
In order to achieve the first object, according to the present invention, a circular knitting machine for knitting a knitted fabric by moving a sinker between reciprocating knitting needles is used as a stitch knitting method. 25 and a step change sinker 20 having a sinker ecbo 26 lower than the top is used. When the knitting of the knitting yarn 60 by lowering the knitting needle 30, the step change sinker 20 moves in the axial direction of the circular knitting machine. Accordingly, the knitting needle 30 draws the knitting yarn 60 with the knitting yarn 60 on the sinker top 25 and forms the normal stitch S1 with the normal stitch length Y1, while the knitting needle 30 with the knitting yarn 60 riding on the sinker exbo 26. Draws the knitting yarn 60 and forms a small stitch S2 with the small stitch length Y2.
When such a stitch knitting method is employed in forming a stitch with various sock circular knitting machines, the axial center direction of the circular knitting machine of the stitch changing sinker 20 can be used without changing the reciprocating mechanism of the knitting needle by the stitch cam. By simply switching between the forward and backward movements, it is very easy to knit a sock that conforms to the shape of the foot by increasing the degree required for the function of the sock and reducing the degree of tightening the foot.
[0014]
When the stitch change sinker 20 is advanced or retracted in the axial direction of the circular knitting machine, the forward action of the sinker select butts 21 to 24 protruding and formed outside the rear portion of the stitch change sinker 20 is performed by the sorting drive, and the rear end of the stitch change sinker 20 It is preferable that the sinker bat 27 protruding from the edge be subjected to the receding action. The number of steps of the sinker select bats 21 to 24 may be four or less or more. The number of steps of the sinker select bats 21 to 24 is selected according to the response speed of the actuator 40 (described later) to the rotational speed of the knitting machine.
[0015]
When the sinker select bats 21 to 24 are selectively driven, it is preferable to use an electronic signal using the actuator 40. The actuator 40 performs a sorting operation using a piezoelectric phenomenon of a piezo element, and its driving is controlled by ON / OFF of an electronic signal. Thus, the sinker select bats 21 to 24 can be selected and driven very easily.
[0016]
In knitting a sock, when using a sock circular knitting machine as a circular knitting machine, corresponding to each part of socks such as a forefoot part, a hindfoot part, using the stitch knitting method with the circular knitting machine, the same. The stitches may be knitted in the knitting structure of the course according to the size of the stitches such as the normal stitch S1 and the small stitch S2. Thus, it is possible to knit a stitch in accordance with the size of the stitch corresponding to each part of the sock very easily.
[0017]
In order to achieve the second object, in the present invention, a sock circular knitting machine of a multicolor pattern composed of a pattern portion and a ground portion is used as a circular knitting machine, and the pattern portion has a small stitch and the ground portion has a stitch. The method of knitting to a large stitch is adopted. By employing this method, the pattern portion can be clearly displayed.
[0018]
Further, in order to achieve the third object, in the present invention, when performing the design of the cut boss pattern using a sock circular knitting machine of a multicolor pattern composed of a pattern portion and a ground portion as a circular knitting machine, The boundary is made smaller than the stitch of the ground part and knitting is adopted. By employing this method, the cut ends of the knitting yarn and the pattern yarn can be made hard to come off from the stitch.
[0019]
Furthermore, in order to achieve the fourth object, according to the present invention, when performing patterning, only a specific portion of the knitting structure knitted by combining the change of the knitting structure and the change of the stitch is used as the normal stitch S1 or the small stitch S2. It adopts a method of displaying a handle. By employing this method, the display effect of the pattern can be increased.
[0020]
When a pile sinker is used as the sinker, a pile stitch changer 20b having a pile excavator 26b formed below a pile loop knitting pile claw 28b at the upper rear portion of the sinker top 25b is used, and the sinker 20b is in a retracted position without moving forward. At this time, the knitting yarn 60 and the pile yarn 62 together form the normal stitch length Y1 with the knitting yarn 60 and the pile yarn 62 riding on the sinker top 25b, while the knitting yarn 60 moves to the sinker exbo 26b by the advance of the sinker. It is effective that the pile yarn 62 forms a pile loop having a pile stitch length P and the knitting yarn 60 forms a small stitch having a small stitch length Y2 in a state where the pile yarn 62 rides on each of the pile claws 28b. In this, the knitting yarn and the pile yarn easily form a stitch having a normal stitch length, Only yarn pile yarn in the small stitch length it is possible to form the stitches to become a pile stitch length.
[0021]
Also, the sock knitted by the stitch knitting method of the circular knitting machine of the present invention allows the stitcher 20 having the sinker top 25 and the sinker exbo 26 lower than the top to enter and exit between the reciprocating knitting needles. While the knitting yarn 60 is on the sinker top 25, the knitting needle 30 pulls the knitting yarn 60 to form a normal stitch while the knitting needle 30 draws the knitting yarn 60 with the knitting yarn 60 on the sinker exbo 26. As a sock knitted so as to form a small stitch, a normal stitch S1, a small stitch S2, etc., in a knitting structure of the same course, corresponding to each part of a sock such as a forefoot and a hindfoot. A sock in which stitches are knitted by size, and a sock with a multi-colored pattern consisting of a pattern part and a ground part. The socks where the land part is knitted to the large stitch and the pattern part is clear, and the sock of the multicolor pattern, and when the cut boss pattern is displayed, the boundary between the pattern and the pattern is the ground part Socks that are smaller than the stitch and make it difficult for the cut ends of the knitting yarn and pattern yarn to come off from the stitch are included.

【The invention's effect】
According to the conventional circular knitting machine and sock circular knitting machine, the stitch size is changed by moving the stitch cam up and down, so that the stitch cannot be changed randomly in the forefoot and the hindfoot of the sock. However, according to the stitch knitting method of the circular knitting machine according to the first aspect, the sinker top is lower than the sinker top on the upper surface of the sinker holding the knitting yarn without changing the reciprocating mechanism of the knitting needle by the stitch cam. Using a stitch change sinker formed with a sinker exbo, by simply switching the movement of the stitch change sinker in the axial direction of the circular knitting machine, extremely easily, the stitch required for the function of the sock is large, and the foot is tightened. It is possible to change the stitch length by selecting the knitting yarn holding part of the stitcher, such as knitting socks that match the shape of the foot by reducing the stitch length. Because without yarn pull-in amount of control by the knitting needles, with can change the time, needle selection mechanism of a conventional needle can be knitting structure knitted by a knitting needle for better it is.
[0037]
According to the second aspect of the present invention, it is possible to easily move the stitch change sinker in the axial direction of the circular knitting machine by using the sinker select bat and the sinker bat formed on the stitch change sinker.
[0038]
According to the third aspect of the present invention, since each of the sinker select bats of the plurality of stitch change sinkers is selected and driven by an electronic signal using an actuator, only an arbitrary stitch of the knitted fabric can be easily formed in a normal stitch or small stitch. It can be formed in a stitch.
[0039]
According to the invention described in claim 4, in knitting the sock, the frequency of the forefoot portion and the hindfoot portion of the sock, which has been impossible in the past, can be changed to an arbitrary distribution.
[0040]
According to the fifth aspect of the present invention, when a sock with a multicolor pattern composed of a pattern portion and a ground portion is knitted by a sock circular knitting machine, the pattern portion can be clearly displayed.
[0041]
According to the sixth aspect of the present invention, in the case of performing the design of the cut boss pattern with a multicolored sock circular knitting machine, it is possible to make it difficult for the knitting yarn and the cut end of the pattern yarn to come off from the stitch.
[0042]
According to the seventh aspect of the invention, it is possible to enhance the display effect of the pattern of the knitted fabric that is easily knitted by combining the change in the knitting structure and the change in the stitch. For example, by forming the portion of the tack knitting structure into a normal stitch and the portion of the plain structure into a small stitch, there is an effect that the portion of the tack knitting structure largely emerges.
[0043]
According to the invention as set forth in claim 8, the stitch having the normal stitch length is formed for both the knitting yarn and the pile yarn by using the pile stitch change sinker having the pile exbo formed as the pile sinker, while the knitting yarn is a small stitch length. Thus, the pile yarn can easily form a stitch having a pile stitch length.
[0044]
According to the ninth aspect of the present invention, socks and knitted stitches of normal stitches and small stitches of equal stitch size corresponding to individual portions of the sock, a stitch portion with a stitch portion with a small stitch, and a ground portion with a stitch portion with a stitch. Knitting yarns and patterns by knitting multi-colored socks with a clear pattern part by knitting the large stitch, and making the border between the patterns smaller than the stitch of the ground part when patterning the cut boss pattern It is possible to easily provide a sock knitted by a stitch knitting method using a circular knitting machine according to the present invention, such as a sock in which a thread cut end is hardly removed from a stitch.
