First, numeral 2 is a V-shaped knitting cam, and an age cam 3 is pivotally attached to its rear end.

The tip of the age cam 3 is normally in elastic contact with the lower rest passage partition plate 4, and the age cam 3 guides the knitting cam 2 toward the knitting cam 2 and advances the knitting needle N that enters from the outside, but the knitting cam 3 guides the knitting needle N that advances from the inside. It will be passed through as is.

Reference numeral 5 denotes an upper rest passage partition, the front part of which constitutes an upper rest passage.

Reference numeral 6 denotes a sub-knitting passage partition which defines a part of the sub-knitting passage between it and the upper pausing passage partition 5.

On the inner side of the partition 6 is a triangular sag cam portion 7, and a swing cam 8 is rotatably provided approximately at the center thereof.

Reference numeral 9 denotes a central sage cam on which a swing cam 10 is rotatably provided.

Reference numeral 11 indicates a sliding arm that moves back the knitting needles that have entered between the partitions 5 and 6 and guides them to the sage cam portion T.

A retraction cam 12 is located below the sag cam portion 7, and a thrust cam 13 is provided at the center thereof.

A tank cam 14 is pivotally attached to the outer lower end of the projecting cam 13, and the tank cam 14 is normally in a non-operating position as shown in FIG.

Pulling cams 16 that are rotatable by a shaft 15 are provided on the outer sides of both ends of the upper pause passage partition 5, and Amicomi cams 18 that are rotatable on the shaft 17 are provided on the outer sides of both ends of the sub-knitting passage partition 6. 1, and the Amicomicam 18 can be moved from the position shown by the solid line in FIG. 1 to the position shown by the two-dot chain line.

A partition plate 19 is provided outside the Amicomi cam 18 and the lifting cam 16, and is composed of an upper rest passage partition part 20, an intermediate cam part 21, and a forward movement prevention part 22.

A forwarding cam 23 is pivotally attached to the outside of the age cam 3, which advances the knitting needles N which have been knitted by the knitting cam 2 again until the loop L of the knitting needles is just before the position where the knitting needle collar NL comes out. The tip of the forward cam 23 is covered within the outer cam 4a of the lower rest passage partition plate 4.
Receiving an elastic force in the direction a, the advancing cam 23 advances knitting needles that enter from inside the carriage that has completed knitting as described above, but passes through the knitting needles that enter from outside the carriage as they are. It looks like this.

24 is a pivot of the forward cam 23, and 25 is a support.

Reference numeral 26 designates a selection plate, which is a retraction partition for slightly retracting the knitting needles once advanced by the forward cam 23, relieving the tension state in which the loop L of the knitting needles is about to slip out, and facilitating the subsequent back-and-forth movement of the knitting needles. 27, a parallel partition wall 28 having a constant height that guides the knitting needles, and a rear guide partition wall 29 that continuously guides the knitting needles rearward.

Reference numeral 30 denotes a descending member, which is located behind the parallel partition wall 28 and has an inclined surface 31 that comes into contact with the knitting needle butt, and a thousand-sided surface 32 that follows this.
A leaf spring 33 is provided on the top surface of the carriage base plate 1.
The knitting needle butt is fixed to the inclined surface 31 and the flat surface 3.
2, the elastic force of the leaf spring 33 applies a downward action to the knitting needle N, causing the knitting needle N to move in the downward position direction.

The height of the thousand planes 32 of the descending member 30 is equal to the height of the parallel partition wall 28.
It is almost the same height.

An elastic member 35 having an inclined surface 34 is pivotally mounted below the lowering member 30 on the same axis 24 as the forward cam 23 .

This elastic member 35 has a spring hanging part 35a projected above the base plate 1, and a coil panel 36 is hung between this and the base plate 1, so that the tip of the inclined surface 34 is imparted with elasticity toward the parallel partition wall 28 side. There is.

37 is a rear rail fixed to the carriage base plate 1, and 3B is a front rail.

Numeral 39 is a needle bed in which a large number of knitting needles N are arranged in a row so that they can be moved back and forth and up and down.

40 is a rear support plate of the needle bed 39, and 41 is a comb tooth press plate 42 provided in front of the needle bed 1, which is fastened to the back surface of the front surface of the needle bed 1.

43 is a needle spring support plate fixed to the comb tooth presser plate 42, and a needle spring 44 is fixed to this, and each knitting needle N is normally attached to the needle spring 44.
However, when the knitting needle butt is pushed downward, it becomes the position shown by the two-dot chain line, and when the downward action is released, the needle spring 44 returns to its original upper position. Returns due to the action of

A plurality of needle selection plates G are provided in front of the rear support plate 40 of the needle bed 39.

The needle selection plate G is composed of a needle selection protrusion T and a needle selection recess S, and the interval between the protrusion T and recess S can be selected as appropriate.
When subjected to a downward action, the protrusion T hits the shank Nh of the knitting needle N and prevents the knitting needle from moving to a lower position.

Conversely, when the knitting needle shank Ns corresponds to the recess S, the knitting needle N
is allowed to move to the downward position.

45 is a pin that supports the needle selection plate G and is fixed to the rear support plate 40.

Reference numeral 46 denotes a long hole provided in the needle selection plate G, into which the pin 45 is fitted so that the needle selection plate protrusion T can move to a position corresponding to or not corresponding to the knitting needles N.

To explain the operation of the above configuration, in FIG. 1, the Amicomicam 18 is moved from the solid line position to the two-dot chain line position.

The cam arrangement of this carriage is two-color simultaneous knitting.

Here, when the carriage is slid on the needle bed 39 in the direction of the arrow in FIG. 1, the knitting standby position knitting needle NA (non-selected needle) butt passes through the path shown by the two-dot chain line.

That is, the forward cam 23 is raised and moved forward by the outer surfaces of the sagging cam 3 and the knitting cam 2, and the sagging cam portion 7, the swinging cam 8,
The center sag cam 9, the swing cam 10, the retracting cam 12, and the inner surface of the knitting cam 2 are used to retract the knitting cam 2, and the knitting cam 3 is lifted up to knit the stockinette fabric through the so-called main knitting path.

On the other hand, the selected needle NB butt passes through a path indicated by a broken line.

That is, the retreating bulkhead 27, the intermediate cam portion 21, and the Amicomi cam 18.
The slide arm 11, the sag cam part 7, the swing cam 8,
The knitting cam 2 is moved backward by the inner surface of the knitting cam 2, and the age cam 3 is lifted up to knit the stockinette fabric through a so-called sub-knitting passage.

By supplying knitting yarns of different colors to the knitting needles NA passing through the main knitting passage and the knitting needles NB passing through the sub-knitting passage, two-color yarns can be simultaneously knitted by one slide of the carriage. Can be knitted.

Knitting needle N that has completed knitting after passing through the main knitting path and sub-knitting path
The butts are positioned and aligned at the lowest end of the knitting cam 2, and the thread crosses between the knitting needle hook Nf and the comb teeth 41 to form a loop L.

When the carriage is further slid, the knitting needle butt moves forward with cam 2.
3, the loop L that was hanging on the knitting needle hook Nf is moved onto the collar NL.

Since the width and height of the collar NL are larger than the hook Nf, the loop L strongly presses the knitting needle, creating a tension state and increasing resistance to the forward movement of the knitting needle N, making it difficult to move.

For the forward cam 23, the loop L is pulled out from the bellows NL and stem N8
(the state shown by the solid line in FIG. 2) in which the knitting needle N is advanced until just before it transfers to the needle N.

When the carriage is further slid, the knitting needle butt moves back to the retreating bulkhead 27.
This time, he retreats slightly less than the width of his hat.

As a result of this retreat, the loop L which was in a tense state is relaxed, the resistance to the back and forth movement of the knitting needle N is reduced, and the back and forth movement of the knitting needle N becomes easier (as shown by the broken line in FIG. 2).

Thereafter, the knitting needle butt moves along the parallel partition wall 28 and comes into contact with the lowering member 30, thereby starting the selection action of the knitting needle.

This selection effect will first be explained with reference to FIG.

As shown by the opening in FIG. 3, needle selection protrusions T of the needle selection plate G provided below the knitting needles N are arranged corresponding to every other knitting needle N.

Here, the knitting hook in which the knitting needle N corresponds to the protrusion T is designated as N1,
When the carriage is slid, the butt of the knitting needle N1 guided along the parallel bulkhead 28 first comes into contact with the inclined surface 31 of the descending member 30, and the elastic force of the plate panel 33 and the elastic force of the needle spring 44 are balanced. However, since the leaf spring 33 becomes stronger than the elastic force of the needle spring 44 with a slight deflection, the tilter 31 attempts to move the knitting needle butt downward, but the knitting needle shank N8 hits the protrusion T and the knitting needle butt moves downward. On the contrary, the leaf spring 33 curves upward, and the descending member 30 escapes upward, and the tip of the knitting needle hat only contacts the inclined surface 31 and the flat surface 32, and moves along the parallel partition wall 28 to the elastic member 35. slanted surface 34
The needle is pushed open as shown in FIG.

Next, the explanation will be given with reference to FIG.

In the case of Fig. 3, knitting needle N1 corresponds to protrusion T.
However, here, the knitting needle that does not correspond to the protrusion T but corresponds to the recess S is assumed to be N2.

When the carriage is then slid, the butt tip of the knitting needle N2 guided along the parallel partition wall 28 first comes into contact with the inclined surface 31 of the descending member 30, causing the leaf spring 33 to bend slightly, but the needle spring 44 Against this, the elastic force of the leaf spring 33 increases, and the inclined surface 31 moves the knitting needle N2 butt downward, and at the same time, the inclined surface 34 of the elastic member 35 moves the knitting needle N2 butt in the direction of the parallel partition wall 28 due to the action of the coil spring 36. Continues to provide elastic action.

When the upper surface of the butt of the knitting needle N2 reaches the surface 32 of the descending member 30, the knitting needle N2 has moved to the lowest position, and at this position, the elastic member 35 moves the knitting needle N2 in the direction of the parallel partition wall 28.
The elastic action of the butt cannot be supported by the parallel partition wall 28, and the knitting needle N2 breaks through the upper surface 28a of the parallel partition wall 28, and is selectively advanced to the position just before the collar comes off (the state shown in FIG. 4).
.

Since the knitting needle N2 is once advanced by the advance cam 23 to a position just before the flange is removed, a weak elastic force may be used to cut off the hat from the upper surface 28a of the parallel partition wall by the elastic member 35.

The knitting needle selected and advanced here becomes the selected needle NB.

Further, in order to prevent the knitting needle N2 bat from moving too far forward due to the elastic force of the elastic member 35, the forward movement preventing portion 22 is provided on the inclined surface 34 of the elastic member 35.

In this embodiment, since the knitting cam and the needle selection member of the carriage are provided symmetrically, the same effect can be obtained even if the knitting cam and the needle selection member of the carriage are slid on the needle bed 39 in the opposite direction.

As described in detail above, in the present invention, the butt of the knitting needle that has been knitted is advanced by the forward cam, and the loop hooked on the hook of the knitting needle is sent to the position just before the collar is removed, and then the knitting needle is retreated by the retreating bulkhead, and the loop is looped by the retreating bulkhead. The knitting needle is changed from a tensioned state to a relaxed state so that it is easy to move the knitting needle back and forth, and then the knitting needle is selected between two positions, front and back, using a parallel bulkhead, an elastic member, a lowering member, and a needle selection plate, making it extremely simple. This has the effect of ensuring reliable performance with a simple structure and operation.
