Description

DETAILED DESCRIPTION OF THE INVENTION This invention guides the butts of knitting needles sorted in the front and back to guide passages spaced apart in the front and back, and crosses the front knitting needle over the adjacent rear knitting needle in front of the sinker needle, and A stitch transfer device that acts on each knitting needle by moving the rear knitting needle back and forth to transfer the bran thread loop held on the front knitting needle to the rear striped needle on the right or left side of the total needle, depending on the direction of movement. The carriage is characterized in that by continuously reciprocating the needle bed, the knitting needle butts on both sides of and behind a specific rear knitting needle are removed and guided from the rear guide path to the front guide path. shall be.

The carriage for transferring the stitches of the secondary kettle is Tokuseki Sho 48-53042.
As shown in the publication, the batts of striped needles that have been sorted forward and backward are initially guided to separate guide paths, during which so-called green eye transfer is performed, but after that, all knitting needle batts are the same. After passing through the guide passage and exiting the carriage and moving in one direction, all the knitting needles were aligned in a line. Therefore, as shown in Fig. 6d, a specific bran needle N
Conventionally, when knitting a so-called three-fold pattern in which the bran needle loops L, L3 held by the knitting needles N, N3 on both sides of the navel are knitted, the pattern described in Tokkokuki No. 51-7253, for example, has been used. The knitting carriage (main carriage) A equipped with a needle selection device that operates based on the needle selection signal recorded on the needle selection card as shown in FIG. After moving the striped needles N across the knitting section to the position indicated by the two-dot chain line in FIG. ) Set B to the solid line in Figure 8 and move it to the position indicated by the two-dot chain line in the figure, and as shown in Figure 6c, it is held by the front knitting needles N and N5 adjacent to the specific rear striped needles N2 and N6. Move the knitting yarn loops L and L5 that are currently in use, then remove the sub-carriage B (double-dashed line in Figure 8) from the needle bed C, and move the main carriage A from the position shown by the two-dot chain line in Figure 8 to the position shown by the solid line. Then, knitting needles N3 and N7 in Fig. 7 are placed in front of knitting needles N, , N2, N
After sorting again so that 4, N5, and N6 are located at the rear, it is necessary to set the previously removed subcarriage B again to the position indicated by the two-dot chain line in Fig. 8 and move it to the position indicated by the solid line in the same figure. In addition to operating the main carriage A, move the sub carriage B to the needle bed C.
The operations of removing the needle from the needle bed C and moving it by placing it on the needle bed C become complicated, making it difficult to improve work efficiency.Also, the needle selection card, which controls the operation of the needle selection device of the main carriage A, is a three-way stack. Two stages of needle selection signals are required for each stage of one piece of the pattern, and if the size of the mist needle card is constant, if there are many stages of knitting of the three-fold pattern, the number of needle selection signals for the main carriage A will be reduced. This had the disadvantage that the number of rows decreased, making it impossible to knit fine and complex patterns. An object of the present invention is to provide a knitting needle sorting device in the sub-carriage so that a three-fold pattern can be knitted only by continuous reciprocating operations of the sub-carriage, thereby solving the above-mentioned conventional drawbacks.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a bottom view of a stitch transfer carriage (subcarriage) B that is capable of reciprocating in the arrangement direction of knitting needles N on a known needle bed C in which a plurality of sinker needles S are arranged in a row at the front end. Needle N

Regarding the presser part B, one end of the substrate 1 whose free end extends from the back of the sinker S to the front beyond the upper end thereof is bent downward, and the knitted fabric presser 23 is horizontally supported at the lower end. do. At the bottom end of the board 1,
At both ends corresponding to the rear of the sinker needle S, lug raising plates 24a and 24b are fixedly arranged to engage and raise the lug of each of the front and rear knitting needles that have entered the paths la and oa from outside the sub-carriage B. , a latch raising plate 24 corresponding to right above the sinker needle S
Magnets 25a and 25b are fixedly arranged in front of magnets a and 24b. In addition, a back latch support plate 26 is fixedly arranged at the center of the base plate 1 corresponding to the front side of the sinker needle S to maintain the lug of the rear striped needle in an upright state on the front end surface, and the lug is raised on both sides of the front side. Hold the latch of the front knitting needle erected by the plates 24a and 24b until the hook of the rear knitting needle enters into the green yarn loop L of the bran needle at the rear in the direction of movement of the sub-carriage B and behind the direction of movement of the striped needle. The front blade support plates 27a and 27b are fixedly arranged to maintain the erect position against the tension of the rope loop L at intervals, and the front blade support plates 27a and 27b are further moved forward to the position where the blade is removed. Sub-joint pieces 28a and 28b are fixedly arranged to engage the hooks of the front knitting needles and bend the stems protruding from the needle beds of the bran needles against the elastic force of the stems. On the upper surface of the knitting presser body 23, there is a lifting mechanism that engages the hook and stem of the front knitting needle with the engaging pieces 28a, 28b and pushes them upwards above the sinker stitch S from immediately before they engage to immediately after the engagement is released. The cam 29 is fixedly arranged. This invention has the above configuration,
Next, this effect will be explained.

In the state indicated by the solid line in FIG. 5, the blocking portion of the sorting body 16 is
The bat n3, which is located outside (downward) of the rotation path of 1 and moves to the right in FIG. l
This is a state adapted to knitting a three-fold pattern that joins a. When the knob 19 is pulled upward from this state, the ball 18 disengages from the groove 14a of the shaft 15 against the leaf spring 17 and engages with the groove 14b, and the sorting body 16 is held at the position indicated by the two-dot chain line in FIG. Ru. As a result, the cam portion 16a of the sorting body 16,
16b retreats upward from the movement path of the bat in paths lc and roc, and the blocking portion 16c is located within the rotation path of the locking body 21, so the swing cam 11b rotates to the position shown by the solid line in FIG. 3. Then, the locking body 21 is blocked by the blocking part 16c of the sorting body 16, and all the bats passing through the paths lc and oc join the path oa, which is a state adapted to normal stitching. Next, with the knob 19 selected in the upper position, it is assumed that the knitting needles N are selected in the manner shown in FIG. From this state, when the sub-carriage B is first moved in the direction of the arrow x in Fig. 1 (to the right in Fig. 7), the butts of the knitting needles N, N5, which were sorted forward, enter the path la, and are sorted backward. green needles N2, N3, N4, N6,
Each bat of N7 enters the path na.

Below, we will mainly explain the adjacent front and rear striped needles N, N2.
The front knitting needles N and the back knitting needles N2 each move the latch raising plate 24a and the magnet 2 until they reach the point X, 1× in Figure 1.
5a, and the latch of the striped needle N is controlled by the front latch support plate 27a, and the latch of the knitting needle N2 is controlled by the rear latch support plate 26 to maintain the tension of the rope loops L, , L in the hook. maintained in an upright position against When the front knitting needle N, reaches the point X,1×, both sides of the hook hit the right side of the engaging piece 28a in FIG. The portion protruding from the front end of the floor C is bent in the direction of the subsequent striped needle N2 against the elastic force. At this time, the stems of the front knitting needles N, are pushed up above the sinker needles S by the lifting cam 29a, so the front knitting needles N, 'mai sinker needles S, as shown in FIG.
2, moves over the stem of the rear knitting needle N2 and intersects it, and at the point X2-
If it comes off from a, the sinker will move one stitch S,, S2 due to its own elasticity.
Return in between. On the other hand, the rear knitting needle N2 moves forward along the front surface of the rear cam body 4a, and its hook enters the knitting yarn loop L shown in FIG.
At the X2-X2 point, the front knitting needles N and sinker needles S2 and S
When the knitting needle returns from between 3 and 3 to between S and S2, the knitting yarn loop L of the front knitting needle N is captured by the hook of the rear knitting needle N2, as shown in FIG. 6b. In addition, in X2-x2, the latch of the rear knitting needle N2 continues to be maintained in an upright state at the front end of the rear knitting needle support plate 26, but the latch of the front knitting needle N and the latch come off the front knitting needle support plate 27a and are free. Therefore, the side thread loop L, by its own tension, knocks the latch backward and climbs on top of it. Therefore, by further moving the sub-carriage B and moving the rear line needle N2 backwards along the rear surface of the rear cam body 4b in advance of the front knitting needle N, the knitting yarn loop L can move the front full needle N and the latch. Go to the back and climb on top of that stem, and then the front knitting needle N is delayed.
, retreats along the middle cam body 3b and its hook moves to the rear of the sinker needle S, so that the knitting yarn loop L is removed from the front knitting needle N, past the hook, and the front striped needle N, is transferred to the rear knitting needle N2. The knitting yarn loop L of is transferred. That is, as the carriage moves, the cotton yarn loop of the front needle is transferred to the rear knitting needle adjacent to the front needle in the direction of movement of the carriage, and finally all the bats swing the cam 11b from the two-dot chain line to the solid line in FIG. Since the batts are removed from the carriage through the path oa and lined up in a line at the position of the rear knitting needles, even if sub-carriage B is moved in the opposite direction after stitch transfer, all batts will not be attached to the rear knitting needles. The stripes do not change just by passing through the route. Further, when the knob 19 is selected to the lower position, the cam portions 16a and 16b of the sorting body 16 enter the corresponding paths lc and Dc of the bat, and the blocking portion 16c moves into the rotation path of the engaging body 21. Therefore, if the sub carriage B is further moved after the knitting yarn loop has been transferred as shown in Fig. 6c by the same action as described above, the rear side where the paper yarn loop L has been transferred as shown in Fig. 2 is The butt crest of the knitting needle N2 engages with the slope of the cam portion 16b of the sorting body 16, pushes it out of the path c against the elastic force, and moves straight, and the butt ridge of the subsequent rear knitting needle N3 engages with the slope of the cam portion 16b of the sorting body 16, and moves straight. When reaching the position corresponding to the flat part of the part 16b, the butt n of the previous knitting needle N, touches the cam part 1 as shown in FIG.
As the bat n3 moves clockwise around the shaft 15, the bat n3 is pushed forward by the flat part of the cam part 16b and moves from the path c to the path c. Move to od.

Also, since the blocking part 16c of the sorting body 16 is removed from the path of the locking body 21 and the swinging cam 11b can freely rotate against the elastic acting force, the butt n and the mountain are moved along the path l from the state shown in FIG.
After passing through the swing cam 11b and rod d, the swinging cam 11b and the bypass cam 13 are removed forward and the bat exits from the path la, and the bat continues along the path rod c, eliminating the swinging cam 11b and exiting from the path Da. The shape of the needle is as shown in FIGS. 7a to 7b. Therefore, when the sub-carriage B is moved backwards to the right in FIG. The next knitting needle N in the moving direction of the sub-carriage B is
The bran thread loops LA, L5 of knitting needles N, N5 are crossed over the stems of needles 2, N4, and N6, and the same action as above is repeated.
has already been transferred to knitting needles N2 and N6, so the knitting yarn loops of knitting needles N3 and N7, which have newly become front knitting needles, are captured and transferred to rear knitting needles N2 and N6 as shown in Fig. 6d. On the hooks of knitting needles N2 and N6, their own knitting yarn loops overlap with the two loops of the striped yarn loops of the rope needles on both sides, so that a so-called three-fold pattern is knitted. As described above, the present invention is capable of reciprocating so that the cotton yarn loops of the knitting needles on both sides of the knitting needle are transferred to a specific backward knitting needle that receives the cotton yarn loops of the adjacent front striped needles during the forward movement. When one end of the knitting needles passes through the guide passage, it engages with the butt of each knitting needle, and when one end retreats out of one guide passage, the other end enters into the other guide passage, and the needle thread loop of the leading knitting needle moves to one side. After moving to a specific knitting needle adjacent to the other needle, a sorting body is arranged in relation to both guide passages so that the butt of the rear knitting needle adjacent to the other needle is removed from the rear guiding passage, and the sorting body is used to remove the butt of the rear knitting needle from the rear guiding passage. The structure includes a guide path that guides the knitting needle butt that has been knitted to the front guide path, so that the forward movement of the carriage causes the striped yarn loop of the adjacent striped needle to be transferred to a specific rear knitting needle, and the subsequent carriage Because the knitting yarn loop of the bran needle adjacent to the other knitting needle is transferred to a particular back-loop knitting needle by the return movement of It allows for pattern formation and has excellent operability.

In addition, when the sub-carriage moves forward, the needle selection mode for the next stitch remains, so the mist needle card of the main carriage contains three needle selection signal sequences that create the needle mode for the forward movement of the sub-carriage. Since only one row is required for each self-stacking knitting stage, compared to the conventional system which requires two rows of needle selection signals for each three-self piling knitting stage, it is possible to make the main carriage's needle selection signal rows of the same length. It has the effect of being able to record a large amount on a signal card and making it possible to knit a thin and complex pattern.

In the above-mentioned embodiments of the present invention, the sorting body is installed only on one side of the sub-carriage, and the sub-carriage is always moved back and forth in the direction indicated by the arrow in FIG. However, the same effect can be obtained by installing the sorting bodies on both sides so that knitting can be performed no matter which direction the sub-carriage moves first.

Further, in the above embodiment of the present invention, the stem of the front knitting needle is crossed over the stem of the adjacent back knitting needle by crossing the sinker needle. A similar effect can also be obtained by having the stem of the needle cross over the stem of the adjacent rear knitting needle.

Furthermore, in the above-described embodiment of the present invention, the rear knitting needles that undergo stitch transfer enter the rope yarn loops of the front knitting needles, but when the rear knitting needles move forward, they pass directly outside the cotton yarn loops of the front knitting needles. A similar effect can be obtained by configuring the knitting yarn loop to be captured and transferred by the hook when the knitting yarn loop is moved backward.
