[0018]
In the circular knitting machine described above, in the embodiment of the present invention, the perelin knitting needle 3 is constituted by the first perelin knitting needle 3A and the second perelin knitting needle 3B, and the first perelin knitting needle 3A and the second perelin knitting needle 3B As shown in FIGS. 3 to 8, the tip portions 32a and 32b protruding into the sinker loop of the knitted fabric, and the tip portions 32a and 32b are connected to each other in the thickness direction of the thin plate-like body. Bulges 34a, 34b having hooks 33a, 33b formed by cutouts for hooking sinker loops; and bulges 34a, 34b, leading ends 32a, 32b and bulges. The shaft portions 35a and 35b are wider than the projecting portions 34a and 34b. The shafts 35a and 35b are provided with protruding pads 31a and 31b that fit into the sliding grooves 61 of the cam 6.
[0019]
Then, the first Perelin knitting needle 3A and the second Perelin knitting needle 3B are provided with bulging portions 34a, 34b having hooking portions 33a, 33b so as not to interfere with each other when they are mounted in the adjacent knitting needle mounting grooves 12. It is formed at a different position that does not overlap with the advance / retreat direction of the vera knitting needle 4 attached to the dial 2.
[0020]
Specifically, as shown in FIG. 8, the tip portions 32a and 32b are overlapped at the same position, and the positions where the hook portions 33a and 33b are formed are at the same height in the length direction of the thin plate. The first perelin knitting needle 3A and the second perelin knitting needle 3B are formed such that the bulging portions 34a and 34b are shifted from the shaft portions 35a and 35b in the width direction so as not to overlap with each other.
[0021]
In the present embodiment, as shown in FIG. 3, the first perelin knitting needle 3A is formed such that the bulging portions 34a, 34a are bilaterally symmetric, and the bilaterally symmetric first perelin knitting needle 3A is formed into two bulging portions. The portions 34a, 34a are overlapped so as to form a hole 36a, and the overlapped portion is mounted in one knitting needle mounting groove 12. Also, in the second Perelin knitting needle 3B, the bulging portions 34b, 34b are formed so as to be left-right symmetric, and the left-right symmetric second Perelin knitting needle 3B is formed with the hole 36b by the two bulging portions 34b, 34b. The knitting needle mounting groove 12 is mounted on the knitting needle mounting groove 12. In addition, both the first perelin knitting needle 3A and the second perelin knitting needle 3B have their shaft portions 35a or 35b fixed to each other, and the tip portions 32a or 32b are overlapped so as to be separated from each other.
[0022]
Therefore, as shown in FIG. 3, the shapes of the holes 36 a and 36 b formed by the bulging portions 34 a or 34 b by laminating the thin plate-like members are as follows. When viewed from the front, the first Perelin knitting needle 3A and the second Perelin knitting needle 3B have the same shape, but as shown in FIG. 8, the first Perelin knitting needle 3A and the second Perelin knitting needle 3B are overlapped and viewed from the side. In some cases, the bulging portion 34a of the first Perelin knitting needle 3A is positioned so as to be displaced from the bulging portion 34b of the second Perelin knitting needle 3B on the side where the vera knitting needle 4 advances.
[0023]
Then, the first perelin knitting needles 3A and the second perelin knitting needles 3B having different positions of the bulging portions 34a and 34b are alternately mounted in the knitting needle mounting groove 12.
[0024]
The first Perelin knitting needle 3A and the second Perelin knitting needle 3B have the same overall length, and the positions of the pads 31a and 31b formed in the length direction thereof and the hook 33a. , 33b are also at the same height.
[0025]
In this way, when the two-layered first Perelin knitting needle 3A and the two-layered second Perelin knitting needle 3B are alternately mounted in the knitting needle mounting groove 12, as shown in FIG. The swelling portion 34a of the second perelin knitting needle 3B is arranged so that the swelling portion 34b partially overlaps when viewed from the front, and when viewed from the side, as shown in FIG. Since the protrusions 34a and 34b are shifted from each other in the direction in which the knitting needle 4 advances and retracts, the expansion of the swelling portions 34a and 34b is not interfered by the swelling portions of the adjacent Perelin knitting needles.
[0026]
Therefore, according to the present invention, it becomes possible to mount the Perelin knitting needles 3 in all the knitting needle mounting grooves 12.
[0027]
Then, the perelin knitting needle 3A or 3B causes the leading end 32a or 32b to dive into the sinker loop by the advance operation in the cylinder 1, and hooks the sinker loop to the hook 33a or 33b formed on the bulging portion 34a or 34b. While the loop was expanded, the two wrench knitting needles 4 were inserted into the holes 36a or 36b formed by the bulging portions 34a or 34b, so that the loops were locked by the hooks 33a or 33b. The sinker loop is dropped on the knitting needle 4.
[0028]
One watermark formed at this time has a width of two vera knitting needles 4.
[0029]
The advancing and retreating operation of the Perelin knitting needle 3 in the cylinder 1 is driven by an annular cam 6 disposed around the cylinder 1. The cam 6 has a sliding groove 61 for moving the Perelin knitting needle 3 on the surface facing the cylinder 1, and the pads 31 a and 31 b of the Perelin knitting needle 3 are fitted into the sliding groove 61. However, the sliding groove 61 is branched in the middle, and when the pad 31a or 31b is guided by the upper sliding groove 61a, the Perelin knitting needle 3 moves forward and backward, and the lower sliding groove 61a. When the bad 31a or 31b is guided to 61b, the Perelin knitting needle 3 does not perform the forward / backward movement.
[0030]
Further, the pads 31a and 31b of the Perelin knitting needle 3 are guided by the needle selecting mechanism 10 into the upper-layer sliding groove 61a or the lower-layer sliding groove 61b. It comprises a jack 5 disposed below the knitting needles 3A, 3B, an actuator 8 for pressing or separating the jack 5 toward the cylinder 1, and needle selecting cams 91, 92. The drive of the actuator 8 is controlled by a computer (not shown) incorporated in the circular knitting machine.
[0031]
When a predetermined jack 5 is pushed by the operation of the actuator 8, when the actuator 8 pushes a lower portion in the longitudinal direction of the jack 5, a pad 51 provided above the jack 5 in the longitudinal direction is moved to an upper needle selection. When the actuator 8 pushes the central portion of the jack 5 in the longitudinal direction, the pad 52 provided below the jack 5 in the longitudinal direction is fitted to the lower needle selecting cam 92. The upper needle selecting cam 91 is used for lowering the jack 5, and the lower needle selecting cam 92 is used for raising the jack 5.
[0032]
When the perelin knitting needle 3A or 3B is advanced, the pad 52 provided below the jack 5 in the longitudinal direction is fitted to the needle selecting cam 92, and the jack 5 starts the ascending operation and starts operating. The pererelin knitting needle 3A or 3B which comes into contact with the cam 6 is guided by the upper-layer sliding groove 61a of the cam 6, and the pererelin knitting needle 3A or 3B starts to move forward and backward, and the perforin knitting needle 3A or 3B forms a watermark. is there.
[0033]
In the present embodiment, as shown in FIG. 10, control is performed such that the first perelin knitting needle 3A and the second perelin knitting needle 3B advance alternately.
[0034]
When the first perelin knitting needles 3A and the second perelin knitting needles 3B are alternately advanced in this manner, a watermark as shown in FIG. 11 can be knitted. Can be knitted at a desired position with respect to the wale.
[0035]
In addition, as shown in FIG. 12, the control of the needle selection of the first Perelin knitting needle 3A and the second Perelin knitting needle 3B is such that some of the first Perelin knitting needle 3A and the second Perelin knitting needle 3B are advanced simultaneously. You can also. Also in this case, it is possible to knit a watermark over two wales at a desired position with respect to all wales.
[0036]
In the case where the first perelin knitting needle 3A and the second perelin knitting needle 3B are alternately mounted in the separate knitting needle mounting grooves 12 as in the above-described embodiment, the formation positions of the bulging portions 34a and 34b. Are displaced in the direction in which the vera knitting needle 4 advances and retreats, so that the engaging portions 33a and 33a of the first Perelin knitting needle 3A and the engaging portions 33b and 33b of the second Perelin knitting needle 3B deviate in the advance and retreat direction of the vera knitting needle 4. Will be located.
[0037]
For this reason, the magnitudes of the tensions of the sinker loops locked by the respective hooks 33a and 33b are different from each other, so that an even tension cannot be obtained and an excessive force may be generated in the yarn. In the second Perelin knitting needle 3B located on the retreating side of the vera knitting needle 4 having a weak force for pulling the sinker loop, the sinker loop may come off the hooks 33a and 33b and may not be transferred to the vera knitting needle 4.
[0038]
Therefore, as shown in FIG. 7, the hooks 33b, 33b of the second Perelin knitting needle 3B close to the sinker loop are formed with a notch at an acute angle to prevent the yarn from coming off.
[0039]
Further, in the above-described embodiment, two first perelin knitting needles 3A in which the bulging portions 34a and 34b are symmetrical are stacked and mounted in one knitting needle mounting groove 12, and the bulging portions 34a and 34b are Although two symmetrical second Perelin knitting needles 3B are superposed and mounted in one knitting needle mounting groove 12, the first Perelin knitting needle 3A and the second Perelin knitting needle are arranged as in the embodiment shown in FIG. 3B, the first pererin knitting needle 3A and the second pererin knitting needle 3B having different swelling positions and swelling directions of the bulging portions 34a and 34b are overlapped, and the first pererin knitting needle 3A and the second knitting needle 3A are overlapped. The two perelin knitting needles 3B may be mounted in one knitting needle mounting groove 12. At this time, the combination of the first perelin knitting needle 3A and the second perelin knitting needle 3B to be superimposed is one, and the same combination is mounted in the adjacent knitting needle mounting groove 12.
[0040]
In this way, the first perelin knitting needle 3A and the second perelin knitting needle 3B are configured such that the bulging portion 34a or 34b of one perelin knitting needle 3A or 3B is turned into the other perelin knitting needle 3B or 3A like a roof tile. Can be arranged so as to always overlap the bulging portion 34b or 34a in the same state, so that all the perelin knitting needles 3 can pull the sinker loop with a uniform force. As a result, the force applied to the yarn is equalized, and stable knitting can be performed.
[0041]
It is needless to say that the present invention can be applied not only to a circular knitting machine but also to a flat knitting machine as in the above-described embodiment.
[0042]
Further, the Perelin knitting needle may be mounted in all of the knitting needle mounting grooves of the cylinder, or the Perelin knitting needle and the spatula knitting needle may be knitted alternately with a desired knitted fabric pattern, for example, an open stitch pattern and a rubber knitted pattern. As in the case and the like, the Perelin knitting needle and the spatula knitting needle may be arranged in the cylinder.
[0043]
Further, in the knitting machine for weft knitting structure knitting of the present invention, it is possible to increase the density of the watermark on the knitted fabric. Can be knitted. Conventionally, knitting of a watermark can be performed even in a wale where a watermark could not be knitted. Since a watermark can be knitted on any wale, a watermark having a width of 2 wales can be formed. Knitting can be performed at a desired position for all wales, and diversification of patterns at the time of knitting becomes possible.
[0044]
Further, according to the present invention, since the density of the open stitches on the knitted fabric can be increased, knitting of a Russell-like mesh knitted fabric is also possible.
[0045]
