Description

[Detailed description of the invention] [Industrial application field Σ The present invention relates to a stitch widening method for increasing stitches during stitch knitting, and a knitting cam that can perform stitch widening. [Conventional technology]

Conventionally, when knitting a knitted fabric by hand, the widening stitches as shown in Figure 8 are used (the illustrated example is a left widening stitch, and similarly there is a right widening stitch),
The knitting stitch increase shown in FIG. 8 is known, and has been used, for example, to increase the knitting width in molded knitting, or to create an Aran pattern. However, no automatic knitting machine capable of performing these knitting operations has been known so far. I. Problems to be Solved by the Invention In view of the above-mentioned points, an object of the present invention is to obtain an automatic knitting machine capable of knitting widening stitches, which has not been conventionally performed by automatic knitting machines. 1. Means for Solving the Problems] In the method of the present invention, a compound needle is inserted into a needle groove, and a compound needle is inserted into a first compound needle whose tips are opposed to each other. The needles of the second needle bed that are locking the stitches of one of the needle beds are raised to the transfer position, and the needles of the opposing needle bed are raised into the stitches that are locked to the second needle bed. After insertion, the knitted fabric loop is locked to the hook of the opposing needle by lowering both needles, and when the needle that has been raised to the transfer position is lowered, it is locked to the lowering needle. By re-locking the stitch that has been removed in the hook of the descending needle, the stitch is changed to the first stitch. It was made to span the needle of the second needle bed. In the cam of the present invention, the lateral IrA has a knitting lock and a transfer lock for separately operating the needle body and slider of the compound needle.
In the machine needle steering cam, a slider descending surface is provided to lower the slider at an earlier timing than the descending surface of the needle body lowering cam of the stitch transfer side cam of the transfer lock.

[Embodiment 1] Next, an embodiment of the method of the present invention and a needle steering cam for a flat knitting machine that implements the method of the present invention will be described. FIG. 1 shows a cam lock 1 of the carriage viewed from below, and FIG. 2 shows a needle 2 placed at a position corresponding to the cam lock 1. Select jack 3, selector 4. The side view of the select jack brefsa 5 etc. is shown. The needle 2 used in the device of the present invention is a compound needle, and a slider 7 is slidably inserted into the upper part of the tip of the needle body 6, and by operating the ζ slider butt 8, the slider 7 moves the needle body 6. The hook 9 can be opened and closed. 10 is a needle butt provided on the needle body 6. Select Jack Butt 1
1 is provided with concave portions 12, 13, and 14 at its base, and is engaged with a wire 15 provided through a needle bed (not shown), thereby regulating the position of the select jack butt 11. When the wire 15 is engaged with the concave part 12, it is in the welt position, when it is engaged with the concave part 13, it is in the tuck position, and when it is engaged with the concave part 14, it is in the knit position. The select jack bulleter 5 is an elastic plate body with a U-shaped side surface, and its upper edge abuts against a strip plate 16 inserted through a needle bed (not shown), and presses the select jack 3 with its end. , biasing the select jack butt 11 in the upward direction. 17 is a selector bat of the selector 4. The lock 1 consists of a knitting lock 22 and a transfer lock 23 provided on a cam plate 21. The knitting lock 22 is a needle raising cam 2 having a trapezoidal shape and having slopes on both sides as ascending cam surfaces 24a and 24b.
4. A trapezoidal transfer guide cam 25 which is provided on the same center line as the needle raising cam 24 and has a chevron-shaped concave cam surface 25a, and can freely slide up and down in a V-shape on both sides of the transfer guide cam 25 and the needle raising cam 24. The left and right knitting cams 26A installed in
26B, consists of a lower slider guide cam 27, a middle slider guide cam 28, and an upper slider guide cam 29, which are provided in three stages above the transfer guide cam 25. An arcuate arcuate surface 27a having the same shape as the arcuate arcuate needle butt rising surface 24c provided in the
and a half-height slider butt passage 27 in contact with it.
b1 Slider butt passage 27b has slopes 27c1 and slider descending slopes 27d at both ends, the middle slider guide cam 28 is located above the lower slider guide cam 27, and the middle part has an eight-shaped ascending slope 28a and a half-height butt passage. 28b. Upper slider guide cam 2
Reference numeral 9 is located above the middle slider guide cam 28, and has a transfer guide surface 29a formed with a chevron-shaped recessed portion in the center, and both ends of the transfer guide surface 29a are located above the middle slider guide cam 28. It descends to surround both sides of the lower slider guide cam 27, forming a descending guide surface 29b. The descending guide surface 29b has a half-height, and is provided with a widening descending guide surface 29C parallel to the descending guide surface 29b. The increasing stitch descending guide surface 29C is at full height. The transfer lock 23 is located at the top of the trapezoid of the needle raising cam 24, and is connected to the needle raising cam 24 and the stitch raising cam 30, which has a trapezoidal shape and has a height sufficient to raise the needle 2 to the stitch transfer position. A half-height stitch receiver, which is provided with a chevron-shaped cam surface 31 formed in the center and is swingably provided in a recessed part 32 sunken below the surface of the cam plate 21, serves as a needle raising cam 33 and a transfer guide. It consists of a cam 25. 34 is a fixed guide cam. Below the raising cam 24, a pair of breathers 35A act on the select jack butt 11 in the knitting position to push down the butt 10 of the needle 2 to the half position 1;
35B, select jack butt 1 in tuck position
a pair of pressers 36A that act on and push down 1;
36B, a presser 37 located between them, and a presser 38 having a width larger than the width of the raising cam 24, which acts on the select jack butt 11 at the welt position. Next, the structure of the knitting cam 26 will be explained. The knitting cams 26A, 26B are symmetrically supported opposite the rising cam surfaces 24a, 24b of the raising cam 24 so that they can slide up and down relative to the cam plate 21. The knitting cam 26B will be explained below. The knitting cam 26B is the rising cam surface 24 of the raising cam 24.
The surface facing b is the loop-forming descending cam surface 26a, and the center portion is a recessed portion 41 having a half-height, and a portion located slightly inward from the loop-forming descending cam surface 26a is connected to the recessed portion 41. The opposite side forms a slope 42. Further, at the lower end following the descending cam surface 26a, a step 43 is formed with a height that allows the bat in the half position to pass through, and a needle with a butt in the half position height descends to this step, and the needle in the full position is lowered to this step. The needle, which has a butt height up to this point, is lowered to the lowest end 44, so that a knitted fabric with varying degrees of variation can be knitted. Further, the guide cam 34 is provided with an extension portion 45 extending into the recessed portion 41 of the knitting cam 26B. One side of the extension portion 45 is a descending cam surface 45a, and the cam surface 45a of the transfer 1-holder when the needle is lowered is parallel to the loop-forming descending cam surface 26a of the knitting cam 26B. 46 is a guide cam.
Since the thickening in the method of the present invention coincides with the transfer step 1, the transfer will be explained first. Fig. 3 shows the cam lock 1 that raises and lowers the needle on the side that passes the stitch, and Fig. 4 shows the cam lock 1 that lifts and lowers the needle on the side that receives the stitch. Knitting on needle 2 during transfer. Tuck and welt position selection means are performed by conventionally known means. First, the raising and lowering of the needle on the side where the stitches are passed will be explained with reference to FIG. The breathers 35A, 35B swing to the positions shown by solid lines and do not come into contact with the select jack butt 11, so that the needle butt 10 always maintains its full height. Then, the stitch passing raising cam 30 is made to protrude. When the carriage is moved in the direction of the arrow in FIG. 3, the needle bud 10 of the needle that is about to pass the stitch
moves as shown by the dashed-dotted line at the position ■', comes into contact with the rising cam surface 24a of the raising cam 24, and the cam surface 24
It starts to rise along a (Fig. 3 ■■). During this period, the slider butt 8 also moves as shown in the line I'' in FIG. The tip separates from the hook 9 and begins to open the hook 9, fully opening the hook at the position shown in FIG.
0 (Fig. 3) and rises along the guide surface 30a. During this time, as the needle body rises, the slider butt 8 also moves up the rising slope 2 of the lower slider guide cam 27.
7c (Fig. 3), 28a of the middle slider cam 28. 28b, it rises to the top and becomes a lateral transition. During this time, the stitch amount (described later) is such that the needle on the side rises to the highest point (Fig. 3 ■).
It is inserted into the stitch loop that is locked to the needle on the stitch transfer side. Next, the needle butt with lateral transition 11. The slider butts 8 are lowered by the downward guide surface 25a1 of the transfer guide cam 25 and the guide surface 29a of the upper slider guide cam 29, respectively. While descending the slider butt 8, the middle slider guide 28 and the upper slider guide cam 2! ), and during this period, the slider does not descend, and only the needle body descends, thereby closing the hook (Fig. 3 (■)). The closed hook then remains closed according to the movement of the needle body (Fig.
Guide cam 4 is pulled down to the lowest position (Fig. 3■)
6 (Fig. 3 ■). On the other hand, the stitch amount on the side is 35A. 35B and 37 are swung to the positions indicated by the solid lines in FIG. 4, so that they do not come into contact with the select jack butt 11 that has been selected in the position (3). The stitch amount is explained by moving the needle raising cam 33 in the direction opposite to the direction in which the carriage moves, that is, in FIG. 4, the carriage moves in the direction of the arrow, so it assumes a position swung clockwise. As the carriage moves in the direction of the arrow in FIG.
In contact with the prefixer 36A (Fig. 6 ■), the prefixer 36A
While in contact with (between ■ and ■ in Figure 4) the needle butt 10. Both slider butts 8 will be pushed to their full positions. The needle butt 10 that has shifted to the position ■' in FIG.
Just before it comes into contact with the prefixer 36A, the full position @
The needle raising cam 24 moves straight without contacting the cam surface 24a (Fig. 4 ■), and after the pressure by the preflexa 36A is released (Fig. 4 ■), the needle raising cam 24 enters the concave portion 32 from the descending slope 24 d. (Fig. 6 ■), the stitch amount is from the chevron-shaped cam surface 31 to the needle raising cam 33.
and assumes the highest position (Fig. 4 ■■■). During this period, the slider begins to open as the needle butt 10 starts to rise (Fig. 4 ■), and becomes fully open just before the needle butt 10 reaches its highest point, and the slider rises slightly together with the needle body (after Fig. 4 ■). , needle butt 10
is lowered by the inner cam surface 24e of the needle raising cam 24, and the slider butt is lowered by the O-azu slider guide cam 2fe. However, since the amount of descent of the needle butt 10 is greater than the amount of descent, the slider cannot descend completely with respect to the needle body, and the hook of the needle remains in the open state (FIG. 4, ■). Then, the needle butt 10 advances in a straight line, ascends the slope 24f from the concave portion 32, and leaves the needle raising cam 24, but is subjected to the action of the select jack butt 11 carburetor 36B (between takes the position pushed into the knitting cam 26B, jumps over the descending slope 26a of the knitting cam 26B without contacting it, protrudes again into the recessed part 41 of the knitting cam 26B,
The hook comes into contact with the extension portion 45 of the guide cam 34 and is pulled down by the guide surface 45a (FIG. 4 [phase]) (FIG. 4 [phase]), thereby closing the hook. After that, move to both the needle butt and slider butt with the hook closed. As mentioned above, the needle on the stitch transfer side and the stitch amount are controlled by the needle on the stitch transfer side and the needle on the side for controlling the stitch amount. Figure 5. To explain step by step, as shown in Fig. 5 (■), the needle 2F on the stitch transfer side rises to the highest level, and the stepped portion 2a provided on the shank
Lock loop L to be transferred. At this time, the spring blade 2b of the needle to be transferred is inside the loop L. The position of this needle 2F is the position shown in FIG. 3. Thereupon, the hook 2B is raised into the spring blade 2b, thereby inserting the hook into the loop L to be transferred. The position of this needle 2B is shown in FIG. 4. At this time, the hooks of both 21 bucks are open. Next, as shown in Fig. 5 (■), the needle 2F on the stitch transfer side descends, but the amount of descent of the slider is smaller than the amount of descent of the needle body, so the slider rises relative to the needle body and the hook closes. . The position of the needle 2F at this time is shown in FIG. 3. Then, the needle 2B on the side of the stitch receiver is also slightly lowered, and the loop L is locked to the open hook. The position of the needle 2B at this time is shown in FIG. 4. The stitch receiver, which continues for a while in the above position, moves out of the loop L as shown in FIG. This position is ``■'' shown in FIG. 3 and ``■'' shown in FIG. 4. Next, as shown in FIG. 5, the needle 2B on the side of the stitch receiver starts to descend. This position is indicated by ■ shown in FIG. The hook is closed at the [phase] position shown in FIG. 4, where this lowering ends. Then, as shown in FIG. 5, the needle 2F on the stitch transfer side moves up with the hook closed, preparing for the start of the next knitting. This position of the needle 2F is shown in FIG. 3. Next, the basic form of the widening stitches according to the widening stitch knitting method of the present invention will be explained. In the case of increasing stitches by the method of the present invention, a stitch as shown in FIG. 6 is made, and various variations are developed based on this stitch. That is, there are left stitches, right stitches, A-out stitches, and others, but now, one of the pair of opposing needle beds shown in FIG. 7, for example, the needle FA of the front side needle bed. . Loop fa, fb, fc, -- to FB, FC, ---
Next, an example in which the loop fb of the needle FB is increased to become fb and fbl when knitting is performed with the needle FB locked will be described below. In the increase of the present invention, as is clear from Fig. 6,
A part of the loop fb that is locked to the needle FB of one needle bed provided in the pair is passed to the needle BB of the opposing needle bed as a new loop fb1. In conventional transfer, when a loop is passed to needle BB, the loop is removed from the needle FB that was holding the loop, but in the method of the present invention, a part of the loop is removed from the needle FB without removing the loop. is passed to the opposing needle BB. The loop receiver and transfer will be explained based on the cam lock shown in FIG. This is an example in which the cam lock shown in the upper part of FIG. 8 is increased to the cam lock shown in the lower part. below,
In the above example, the side that separates the stitches is called the opening side, and the side that receives the stitches is called the receiving side. In FIG. 8, the cam lock shown at the top is the opening side, and the cam lock shown at the bottom is the receiving side. The receiving side is Bressa 36A. 36B, stitch passing raising cam 30, etc. take the same position as during transfer. On the open side, the trailing side brev stitch crossing 682 stitch crossing raising cams 30 are respectively located at the working position, and the leading side busessor 36b is set at the non-working position. The carriage moves in the direction of the arrow and selects jack butt 11. Needle butt 10. The slider butts 8 pass through the courses indicated by the dashed-dotted lines It and II'■'', respectively. First, the main body of the needle FB with the loop fb on the open side is
’ course. At this time, the rise of the slider butt 8 is smaller than the rise of the needle butt 10, so as the needle body rises, the slider lowers and the hook opens. Therefore, the loop f that was locked inside the hook
b slides inside the hook and locks the stepped portion 60 of the needle FB. At this time, needle B on the receiving side facing needle FB
Similar to when B is transferred, the stitch receiver is raised by the needle raising cam 33, and the hook 9 is moved to the second needle FB.
The hook 9 is inserted into the blade 61 of the loop f.
b (position ■ shown in Figure 8 and position 9)
Figure ■). Next, the needle FB on the open side is lowered to the transfer guide cam 25, but since the slider passes between the middle slider guide 28 and the upper slider guide 29, the amount of descent is small, and the slider 7 of the needle FB is lowered to the hook 9. The loop f
Hook 7 hooks 9 of needle 8B on the receiving side to part of b (
Position ■ shown in Figure 8, Figure N9 (■). As the carriage continues to move, the select jack butt 11 of the needle FB on the open side comes into contact with the breather 36A and is pushed in. Therefore, the needle butt 10 is pushed into the needle groove, jumps over the cam surface of the knitting cam 26A, enters the concave portion 41, and comes into contact with the descending cam surface 45a of the extension portion 45 of the guide cam 34. At this time, the slider butt 8 is also pushed in, so the upper slider guide cam 2
The select jack butt 11 breaks contact with the breather 36A, and the slider butt 8 that comes out of the needle groove contacts the descending cam surface 29c, so that the slider descends and the hook is released. Open, needle F
Lock the loop fb to the hook 9 of B in the position (■) shown in Fig. 8, (Fig. 9 (■)), and then move both needles FB. BB will be lowered. As a result, the loop fb, which would not be locked to the hook of the needle FB at this position in a normal transfer, remains locked (position ■ shown in FIG. 8, ■ in FIG. 9). And both needles FB, B
As B further descends, the loops fb connected to the respective hooks of both needles become loops fb and fb1 (position marked ■ in Figure M8, ■ in Figure 9). As a first application example of the above, the organization of the left-side enlarged stitches of the organization shown in FIG. 10 will be explained. Figure 11 shows the organization process. A pack bed having needles BA, BB, BC, etc. is provided for the front bed having needles FA, FB, FC, etc., and is latched to the needles FA, FB, etc. of the front bed. The left stitch is added to the previously knitted fabric. Loops fa, fb, . . . are locked to needles FA, FB, . . . on the front bed (Fig. 11, 1). Therefore, we are trying to add one new loop fa1 between loops fb and fc, so first fc and fd. ... is shifted one position to the right as shown in Fig. 11, 4. This means connects the loops fc, fd, ... of needles FC, FD, ... of the front bed to needle B of the pack bed.
C, BD, etc. (Fig. 11 2), then move the pack bed one pitch to the right (Fig. 11 3), and at that position, remove the loops fc and fd that are locked to the pack bed needles BC and BD. The front bed needle FD,
Just move it to FE. In this way, a needle FC having no loop between the front bed needles FB and FD is made (FIG. 11, 4). Next, the front bed needle F
Divide the loop fb that is attached to B into two, and loop fb
Loop fb is attached to the pack bed needle BA located opposite to the front bed needle FB that locks the front bed needle FB.
A part of the loop is locked to form a loop fb1 (Fig. 11, 5). This means is the same as the means explained above with reference to FIG. 9, and the shapes of the loops that engage the needle FB of the front bed and the needle BA of the pack bed are the same as those shown in FIG. It has a basic shape. In this state, if you move the pack bed one pitch to the right, Figure 11 6
The state shown in is reached. And Pacbed Needle B
Transfer the loop fbl hanging from A to the needle FC on the front bed, which does not have a loop, as shown in FIG. 11, 7. Next, needle FA, FC, FD. When a one-coach formation is performed using FE, the result is as shown in FIG. 11. After that, knitting is performed using all the needles of FA, FB, FC, . . . . In the example shown in FIG. 12, which is a modification of the first application example, by reversing the racking direction from the first application example, it is possible to immediately knit all 1-rules after increasing the number of stitches. There is. The knitting process is explained in order in FIG. In this example, the frame passes the loop between the needle FB on the left side of the needle FC which does not have a loop as shown in FIG. 11, and the opposing needle BA, as shown in FIG. 13. Needle FC, needle FD on the right side of BB, which does not have a loop, has a loop at BC. And Figure 13 6
．． As shown in 7, by moving the pack bed one pitch to the left and moving the loop of needle BG to needle FC, the loops that are locked to needles FC and FD are as follows.
In the above example, the loops that are attached to the needles FB and FC shown in FIG. 11 and FC are ovens, but in this example, they are crossed. Therefore, when knitting the next course from the state shown in FIG. 7, all the needles can be used immediately. As a second application example, an example in which the method is used to increase the number of stitches shown in FIG. 14 will be shown below. FIG. 15 shows the organization process, and the process up to FIG. 15 is the same as the first application example shown in FIG. 11. In Fig. 15 6, rank the back bet one pitch to the right, and change the needle BA to the needle F.
Face C. And the loop fbl of needle BA
is transferred to the needle FC (Fig. 14, 7). Next, rack the back bet half a pitch to the left and change the needle BA to the needle FB. Facing the FC and positioning it between them. and needle B
A and all needles on the front bed side FA, FB,...
When the yarn is fed and the needle is pulled down, the state shown in FIG. 15 is reached. Therefore, from this state, rack the front bed half a pitch to the left, and set the needle FA of the front bed,
After transferring the FB loop to the back bet needle BY, BZ, move the back bet one pitch to the left, and move the back bet needle BY, 82. Transfer the BA loop to the front bed needles FZ, FA, and FB (Fig. 15, 9). The example shown in FIG. 16 is also knitted in the order shown in FIG. 17 with an increased knitting ratio of 3 stitches. This creates a third knitting stitch, and by using this stitch to increase the knitting width for forming knitting, etc., it becomes easier to perform forming knitting with an automatic knitting machine, and it also improves the pattern. As an example of this, a pattern using widened stitches, such as an Aran pattern, can be knitted by an automatic machine. Effects of the Invention As detailed above, in the method of the present invention, a compound needle is inserted into the needle groove, and the first
．． The needles of the second needle bed that are locking the stitches of one of the needle beds are raised to the transfer position, and the needles of the opposing needle bed are raised into the stitches that are locked to the second needle bed. A needle that locks the knitted fabric loop to the hook of the opposing needle by lowering it after insertion, and when lowering the needle that has risen to the transfer position, lowers the stitches that are locked to the lowering needle again. By locking the stitch in the hook of the first stitch. By passing it over the needles of the second needle bed, it is now possible to increase the number of stitches, which was possible with hand knitting but not possible with automatic flat knitting machines. Eyes, right enlarged eyes 9
It can be used to increase the knitting width in molded knitting, etc. by increasing the knitting stitches, etc., making it easier to knit with automatic knitting machines, and also for pattern expression, for example, by increasing the knitting width such as in Aran patterns. It became possible to knit the used patterns using an automatic machine. In addition, in a needle operating cam for a flat knitting machine having a stitch knitting cam and a stitch transfer cam that separately operate the needle body and slider of the compound needle, the needle body of the stitch transfer side cam of the stitch transfer cam By providing a slider descending surface that lowers the slider at an earlier timing than the descending surface of the descending cam, it is possible to perform transfer 1- and increase stitches at the same time with the same lock.
Operations that were conventionally performed in two steps can now be completed in one operation, improving organization efficiency.
