Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knitting cam for advancing / retreating a compound needle having one needle advancing / retreating butt, and in particular, a knit in a flat knitting machine that also performs transfer,
Concerning transfer and cam.

[0002]

2. Description of the Related Art Conventionally, a knit / transfer cam for a flat knitting machine is known in which a needle is moved up and down to a knit position, a tuck position, and a welt position for knitting a fabric, and the needle is operated for transferring. (JP-A-4-2847).

In a lock having such a cam, a transfer raising cam for further raising the needle on the transfer side of the transfer is provided above the needle raising cam for raising the knitting needle. While raising the needle on the transfer side, the needle on the receiving side of the transfer is engaged with the step portion provided on the shank of the needle on the stitch transfer side, which has been raised to the highest position in accordance with the timing of the maximum rise of the needle on the transfer side. A stitch receiving side cam that raises the stitch receiving side needle at a timing such that the stitch receiving side needle is inserted into the stopped knitted fabric loop is provided in the central recess of the needle raising cam.

Then, the normal knitting or transfer is carried out by appropriately switching the bat running locus along the cams. The switching of the traveling locus is performed by appropriately protruding and retracting the cam at a predetermined position. However, a plurality of movable cams for switching the above-mentioned normal formation or transfer are required, and the arrangement makes the lock complicated.

[0005]

SUMMARY OF THE INVENTION In view of the above points, the present invention uses only one movable cam for transfer selection in a knitting lock capable of transfer of a type having one needle advancing / retreating butt. By
An object of the present invention is to obtain a knitting cam that can endure long-term use by eliminating troubles such as defective switching during cam control due to the use of a plurality of movable cams.

[0006]

[Means for Solving the Problems] In the upper part of a needle raising cam having a stitch receiving needle raising cam inside,
A stitch passing needle lasing cam having a rising cam surface continuous with the rising cam surface of the needle raising cam is provided so as to be retractable, and the lower edge of the stitch passing needle lasing cam is
A cam surface for lowering the stitch receiving needle having a locus for lowering the stitch receiving needle butt continuous with a needle butt raising locus of the stitch for receiving needle raising cam was formed. Further, the stitch receiving needle raising cam provided in the recess inside the needle raising cam is composed of a fixed cam and a swing cam. Then, at the lower edge of the needle lasing cam top facing the recess provided in the center of the needle lasing cam, an inclined surface following the recess is provided, the needle lasing cam top has a half height, and the stitch passing lasing cam has a full height. The stitch receiving needle along the cam for raising the stitch receiving needle The stitch receiving needle butt that has risen in the ascending path crosses the top of the needle raising cam and contacts the stitch receiving needle descending cam surface at the lower edge of the stitch raising needle I was able to enter the bat descending trajectory.

[0007]

When a normal knit knitting is carried out by the knitting cam mechanism of the present invention, the stitch passing needle lasing cam is sunk, and the needle lasing cam top is made a cam capable of raising the needle to the maximum, and the needle for knitting the stitch is a needle. After being raised by the raising cam and the top of the same cam, it is pulled down by the knitting cam, during which the hook receives the yarn, and the fed yarn passes through the old loop to form a new loop.

In the tuck knitting, when the butt reaches the top of the needle lasing cam before the bat rises to the top of the needle lasing cam, the bat is sunk by the presser so that the butt does not contact the top of the needle lasing cam. Crosses the top of the and is pulled down by a knitting cam. Therefore, the amount of rise of the needle is small by that amount, and the yarn feeding of the previous course which is locked to the hook is not knocked over. Since the yarn for forming a new loop is further provided on the hook, a plurality of yarns are locked in the hook by repeating this. Then, when the needle butt goes up to the top of the needle-raising top cam and is pulled down by the knitting cam, as in the case of knit knitting, the new loop will loop all the yarns that had been locked in the hook until then. It will pass through and you can make tack eyes. To knit a tight-fitting tuck with a loop length shorter than the tuck stitch, do the following. When forming the above tack, the presser works when the bat that crosses the top of the needle raising cam reaches the knitting cam, and the bat is pushed into the needle groove by the presser, and the butt descends the cam surface of the knitting cam. The butt is brought into contact with the descending cam surface of the fixed cam inside the knitting cam, and is lowered by the descending cam surface of the fixed cam.
Since the lowest position is higher than the lowest position by the knitting cam, the new loop created is smaller than the loop by the knitting cam and becomes a tight loop.

The transfer is performed as follows.
The transfer is performed with the stitch passing needle raising cam coming out. On the stitch passing side, raise the needle to the maximum,
After inserting the opening hook of the receiving side needle into the loop that is locked to the step portion provided with the blade of the needle,
By pulling down the stitch passing needle and then the receiving needle respectively, the passing needle is released from the loop and the loop is received by the hook of the receiving needle to complete the transfer.

That is, the needle butt on the stitch passing side rises to the highest position by the needle raising cam and the stitch passing needle raising cam, but the butt of the needle on the stitch receiving side jumps the needle raising cam to raise the stitch receiving needle in the same cam. By the fixed cam and the swing cam, it is lifted up to about the tack position. By this rise, the stitch receiving side needle inserts the hook into the blade of the stitch passing side needle to insert the hook into the loop that is locked to the step portion of the stitch passing side needle, and to the lower edge of the transfer raising cam. The needle butt that has been slightly lowered by the provided stitch receiving needle lowering cam surface and then pushed in by the operation of the presser jumps on the ascending cam surface of the needle raising cam and the descending cam surface of the knitting cam, and fixes inside the knitting cam. The cam comes into contact with the descending cam surface and is pulled down to the original height after the stitch passing side. During this time, the needle on the stitch passing side continues to descend, and the loop is passed to the hook of the needle on the stitch receiving side and goes down to the lowest position of the knitting cam.

When splitting is performed, when the butt of the stitch passing needle is lowered to the tuck position, the butt is pushed in by the presser and jumps on the descending cam surface of the knitting cam and enters the concave portion on the inner surface of the knitting cam. After moving, it is lowered to the height at the start at the descending cam surface of the fixed cam. During this time, the stitch receiving side is pulled down by the stitch receiving needle lowering cam surface at the lower edge of the stitch passing needle raising cam, and the presser is operated to raise the needle raising cam and lower the knitting cam, as in the case of the transfer. Jump the cam surface and horizontally move the recess on the inner surface of the knitting cam. During this time, the loops are locked on the hooks of the needles on both the stitch passing side and the stitch receiving side. Then, both needles are pulled down on the fixed cam surface to the same height position at the start.

The cam 34 has its top protruding in a triangular shape from the top of the stitch receiving side needle raising fixed cam 33 so that the top is located in the recess 28c of the needle raising cam top 28, and the cam 34 swings to the right in FIG. When moved, the ascending cam surface 34a is aligned with the ascending cam surface 33a of the needle raising cam 23, and when swung to the left, the ascending cam surface 34b becomes the ascending cam surface 2 of the needle raising cam 23.
It becomes a line with 3b. The top of the swing cam 34, like the needle raising cam 23, fully projects from the base plate 22.

A stitch passing needle raising cam 40 is provided above the needle raising cam top portion 28. The cam 40 has a chevron shape having left and right ascending cam surfaces 40a and 40b, and the lower edge thereof has a needle raising cam top 2
8 has a recess 40c for receiving the top of the
There are half thick portions 40f and 40g having descending cam surfaces 40d and 40e on the left and right of 0c. The stitch passing needle lasing cam 40 is supported by the base plate 22 so as to vertically project or sink to a full position by appropriate means. The width of the bottom of the cam 40 is slightly narrower than the width of the top of the needle raising cam 23, and the step 44 is formed.
Although forming a and 44b, the rising cam surface 23a of the needle raising cam 23 and the rising cam surface 40a of the stitch passing needle raising cam 40 continue in series. A guard cam 46 is provided via a butt passage 45 so as to surround the top of the cam 40.

The knitting cams 49, 50 having the descending cam surfaces 47, 48 facing the ascending cam surfaces 23a, 23b of the needle raising cam 23 are connected to the butt passages 51, 52.
It can be lifted up and down via the. Knitting cam 49,5
Since 0 has a symmetrical structure, only one knitting cam 50 will be described.

The knitting cam 50 has a loop forming descending cam surface 48 on the surface of the needle raising cam 23 with respect to the ascending cam surface 23b, but has an extremely thin recessed portion 53 at the center portion thereof, and is formed from the loop forming descending cam surface 48. A slope 54 is formed from the portion located slightly inward toward the recess 53.

Further, the concave portion 53 of the knitting cam 50
A guide cam 56 having an inwardly extending extension 55 is provided in a fixed position adjacent to the knitting cam 50. The knitting cam 50 is slidably supported on the base plate 22 in the direction of the loop forming descending cam surface 48 by a member (not shown). One side of the extension portion 55 is a descending cam surface 5 for packing tuck, stitch receiving needle, and split increasing.
7, the descending cam surface 57 is parallel to the loop forming descending cam surface 48 of the knitting cam 50.

Above the guard cam 46 in the center of the lock 21, a slider guide cam 58 that engages with the slider butt 8 for operating the slider 7 of the needle 2 is provided. In the slider guide cams shown in FIGS. 1 and 3, the cam indicated by H is a half height cam, and the cam indicated by F is a full height cam.

On the other hand, the butt 16 of the select jack 10 selected to the A position by the selector 11 is located on the locus along which the butt 16 moves, and below the needle raising cam 23, the A position pressers 60, 61.
Is located on the locus along which the bat 16, which is similarly selected to the H position by the selector 11, moves.
2, 63, and 64 are positioned on the locus along which the bat 16 similarly selected in the B position moves, and the presser 65 is placed.
Are provided respectively. When not operating, the pressers 60, 61, 63 swing upward in FIG. 1, the pressers 62, 64 swing downward, and the presser 65 is fixed. The pressers 60 to 64 may be settled instead of rocking.

The presser 63 determines the needle jack butt corresponding to the needle butt jumping on the needle raising cam top 28 as described above, but the jumping width is large as described above. The presser 63 also has a large length to cover the spread. Therefore, both ends of the presser 63 are located on both sides of the presser 63.
It is necessary to dispose the end portions of Nos. 2 and 64 so as to overlap each other, and they are arranged as in the embodiment.

Next, a knitting method will be described. The knitting, tucking, and miss forming method will be described with reference to FIG. 3. In the above knitting, the stitch transfer side transfer cam 40 is sunk and takes an inactive position.

The knit knitting operation will be described. It is assumed that the carriage has moved in the direction of the arrow in FIG. 3 when knitting the knitted fabric. The knitting, tucking, and welting positions of the needle 2 for knitting are selected by conventionally known means, and the select jack butt 16 corresponding to the needle to be raised to the knit position is positioned at the A position. At this time, the pressers 60 and 61 are in the non-acting position and do not act on the select jack bat 16. Therefore, the butt 5 of the needle comes into contact with the ascending cam surface 23a of the raising cam 23 as shown in the locus of FIG.
Rise along. At this time, since the stitch passing needle lasing cam 40 is retracted, the needle butt 5 that has risen on the ascending cam surface 23a moves horizontally at the position of the shoulder 44a of the needle lasing cam 23 and is maximally elevated by the needle lasing cam top portion 28. While the yarn is supplied from a yarn supplying member (not shown), the needle butt 5 comes into contact with the descending cam surface 46b of the guard cam 46 and is pulled down as the carriage advances. Subsequently, the needle butt 5 is pulled down to the lowermost end by the descending cam surface 48 of the knitting cam 50, while forming a new loop. The needle butt 5 pulled down to the lowermost end is raised to the original position by the guide cam 66.

While the needle 2 is moving up and down, the slider butt 8 draws a locus of A ″ and is lifted by the slider cam 58 after the needle body 3 is lifted up to open the hook 9 and is delayed from the needle body 3 down. And moves downward to close the hook 9. The loci of the needle butt 5 and the slider butt 8 are shown by a chain line.

The tuck knitting operation will be described. The needle for tuck knitting positions the select jack bat 16 at the H position by the operation of the selector 11. Then, the tack presser 63 at the H position is set to the operating position and the other H
The position pressers 62 and 64 are set to non-operating positions.

Assuming that the carriage moves in the direction of the arrow in FIG. 3, the select jack butt 16 and the needle butt 5 move from H to H by moving the positions of the two-dot chain line from left to right.
Move along the two-dot chain line of H '. At this time, since the pressers 62 and 64 are in the inoperative position and the presser 63 is in the inoperative position, the needle butt 5 ascends the ascending cam surface 23a of the needle raising cam 23 and the shoulder portion 44.
Move horizontally from a. Select Jack Butt 1
Since 6 is pushed by the presser 63, the needle butt 5 of the needle 2 corresponding to the select jack 10 is pushed into the needle groove and does not come into contact with the needle raising cam top portion 28, and thus the ascending cam of the cam top portion 28. Without moving up the surface 28a, the shoulder 44a is continuously moved horizontally, and during this time, the new loop is again fed to the hook while the front loop is held by the hook 9, and then the knitting cam 50 is moved.
It comes into contact with the descending cam surface 48 and is descended, and the locus H ′ of the chain double-dashed line is moved as in the case of knitting. During this time, slider 7
Also, the hook 9 of the needle 2 is opened and closed by moving the slider butt 8 up and down by the slider guide cam 58 through the locus of the two-dot chain line of H ″.

A so-called tight-fitting tuck in which the size of the knitted loop is small is knitted as follows. When the needle butt 5 that has been submerged by the presser 63 and passed through the needle raising cam top portion 28 comes into contact with the descending cam surface 48 of the knitting cam 50 in the above-described tack-tack configuration, the presser 64 is placed in the operating position to select. When the jack butt 16 is pushed into the groove by the presser 64, the needle butt 5 jumps on the descending cam surface 48 of the knitting cam 50 along the locus drawn by the dotted line, descends the slope 54 and enters the concave portion 53 of the knitting cam 50, and then guides. The descending cam surface 5 formed on the extended portion 55 of the cam 56
It comes into contact with 7. The descending cam surface 57 pulls the needle butt 5 down to the lowest position.

This lowest position is the knitting cam 50.
Since it is higher than the position where it is pulled down by the descending cam surface 48, the size of the loop knitted is smaller than that when it is knitted by the knitting cam 50, and it is a so-called tight tack.
Such stitches are used, for example, for knitting an intarsia boundary joint. The needle butt pulled down to the lowermost position by the guide cam 56 becomes 2 as the carriage advances.
It coincides with the normal tack locus shown by the dashed line.

When adopting a welt position in which the needle 2 is not raised at all, the selector jack butt 16 is selected by the selector 11 to the B position. Since the presser 65 is fixed and is always in the operating position, when the carriage is moved, the select jack butt 16 is pushed by the presser 65, and therefore the needle butt 5 is also retracted into the needle groove, so that the cam lock 21 is inserted into one of the cams. Needle butt 5 and slider butt 8 do not contact each other,
The needles 2 do not act at all, passing through the positions B'and B ", respectively.

Next, the transfer will be described. When transferring, as shown in FIG. 1, at least in the needle bed on the stitch passing side, the stitch passing needle raising cam 40 is fully projected to the operating position. Then, the stitches are transferred from the needle raised by the stitch passing needle raising cam 40 of the carriage of one bed to the needle raised by the stitch receiving needle raising cam 32 of the carriage of the other side bed.

The transfer for transferring the stitches from the needles of the needle bed of the rear carriage B to the needles of the needle bed of the front carriage F, which are drawn below, will be described with reference to FIG. It is assumed that the front and rear carriages F and B move from right to left in the arrow direction in FIG. 4, and the stitch passing select jack bat selects the A position and the stitch receiving select jack bat selects the H position.

When the select jack butt 16 of the needle 2 on the stitch passing side is selected to the A position and the pressers 60, 61 at the A position are set in the inoperative position and the carriage is moved in the arrow direction, the needle butt 5 causes the pressers 60, 61 to move. 4, the rising cam surface 23b of the needle raising cam 23 and the stitch passing needle raising cam cam 40 as shown by the alternate long and short dash line in FIG.
Of the guard cam 46 and the descent cam surface 46a of the knitting cam 49.

Will guide you to the original height. The locus is shown in Figure 4.
Are indicated by A '.

As described above, the needle butt 5 on the delivery side, which has advanced along the dashed-dotted line of A ', comes into contact with the ascending cam surface 23b of the needle raising cam 23 after passing through the position A in FIG. The slider butt 8 goes straight even after passing through the position A as indicated by A ″. Therefore, the needle body 3
On the other hand, since the position of the slider 7 is low, the hook 9 is in an open state. While maintaining this state, the needle butt 5 on the stitch passing side rises on the ascending cam surface 23b of the needle raising cam 23. The loop that was inside the hook goes out of the hook as it rises, and is locked in the step portion 18 near the blade 17 while surrounding the spring 17, and the needle 2 continues to move the stitch passing needle lasing cam 40 to the highest position. (FIG. 4B position).

On the other hand, in the needle 2 on the receiving side, the pressers 62 and 64 are located in the operating position and the presser 63 is located in the inactive position on the carriage F side. Immediately before contacting the ascending cam surface 23a of the raising cam 23, the select butt 16 of the needle 2 is pushed by the presser 62 in the operating position, so that the needle butt 5 is also pushed into the needle groove. Jump the needle raising cam 23 without engaging the rising cam surface 23a of the needle raising cam 23,
0a, the concave portion 3 in the needle raising cam 23
1 enters into contact with the ascending cam surface 33a of the fixed cam 33 for raising the stitch receiving needle (position in FIG. 4C), ascends the same cam surface 33a, and further touches the ascending cam surface 34a of the swing cam 34 for raising the stitch receiving needle. It touches and is raised (FIG. 4D position). By this rise, the receiving side needle inserts the hook 9 into the blade 17 (shown in FIG. 2) provided on the side surface of the delivery side needle, and inserts the hook 9 into the receiving loop that is locked to the step portion 18. It will be. After passing the point D, the stitch receiving side needle butt climbs over the slope 28d of the half-height needle raising cam top portion 28, climbs over the ascending cam top portion 28, and the descending cam surface 40e at the lower edge of the stitch passing needle raising cam 40.
To the inclined surface 26b (position F in FIG. 4).

The stitch receiving side needle butt 5 which has entered the inclined surface 26b moves up the inclined surface 26b as the carriage advances,
It comes off from the needle raising cam 23. At this time, when the select jack butt 16 is pushed again by the presser 64, the needle butt 5 jumps on the ascending cam surface 23b of the needle raising cam 23 and the descending slope 48 of the knitting cam 50, and enters the concave portion 53 to enter the guide cam 56. It moves horizontally until it comes into contact with the descending slope of the extended portion 55 (position in FIG. 4G) and maintains the height. On the other hand, the needle on the stitch passing side is the descending cam surface 4 of the guard cam 46.
The hook is closed while being lowered before the receiving needle by 6a, and the escape is started from the transfer loop.
Then, the needle passing butt 5 on the stitch passing side, which has descended along the descending cam surface 46a of the guard cam 46, is further pulled down by the descending cam surface 47 of the knitting cam 49, and disengages from the stitch that has been locked as it is, and the stitch is on the receiving side. It remains on the hook of the needle (position in FIG. 4G), and the stitch receiving needle is also pulled down by the descending cam surface 57 of the fixed cam 55.
The slider butt of the needle on the stitch receiving side is slightly lowered by the slider guide cam 58, whereas the hook is returned to the original closed height in the closed state by receiving the stitch because the needle butt causes the needle to descend more. become.

When splitting is performed, the running locus of the needle on the stitch receiving side does not change from that during transfer.
The running trajectories of the needle butt and the slider bat on the stitch passing side are indicated by H ′ and H ″. The stitch passing needle passes through the top of the stitch passing needle raising cam 40 and is pulled down by the descending cam surface 46 a of the guard cam 46. When the needle butt 5 is positioned at the lowest position of the cam surface 46a (position in FIG. 4F), the presser 62 is actuated to push the butt and move it horizontally, so that the hook of the stitch passing needle is locked until then. The hook of the stitch passing needle cannot be removed from the existing stitch, and the hook of the receiving needle is still stitched, and the knitting cam 49 is lowered. The cam surface 47 is jumped, guided to the concave portion in the same cam 49, and pulled down by the descending cam surface 68a of the fixed cam 68. Loop will be locked to both the hook and pass side and the receiving side in the subsequent trajectory.
