Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a needle selection device for a stockinette knitting machine.

[Conventional technology]

Conventionally, a needle selection device for, for example, a horizontal stockinette knitting machine that knits various patterns is equipped with a pair of needle beds 31 facing each other in an inverted V shape, as shown in FIG. A jack 33 is bendably connected to the rear end of a certain knitting needle 32, and a jack lever 35 comes into contact with the needle selection drum 34, which has an uneven surface, and swings around the support shaft 36 at the lower end, thereby keeping the butt 37 of the jack 33 inoperative. In order to be pulled into the position, the knitted fabric A is pushed up to the operating position, and the knitted fabric A comes to descend from the center.

[Problem that the invention attempts to solve]

However, in the needle selection device of this horizontal stockinette knitting machine, when the jack 33 is pushed up to take the operating position (see Fig. 2), the knitting needle cam engages, and the butt, on which a large external force is applied, is engaged. 37
There is a void in the needle groove 38 below the knitting needle 38, which makes the knitting needle 32 unstable, causing unnecessary deflection of the knitting needle 32 to which the jack 33 is connected, resulting in uneven knitting. In addition, as the pattern becomes more complex, the unevenness increases and the needle selection drum 34 becomes larger, and the space between the facing needle selection drums becomes narrower, which hinders the descent of the knitted fabric A, resulting in a complicated and luxurious design. There was a problem that it was difficult to knit a pattern.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention connects the lower end of a swinging member to the jack lever so that it can be bent via a connecting part provided at the upper end, and this swinging member connects to the support shaft at the upper end. It swings up and down using the fulcrum as a fulcrum, and has needle abutment protrusions on the upper edge and needle insertion holes at key points.

[Effect]

According to this invention, a swinging member is further connected to the upper end of the jack lever in contact with the needle selection drum, and this swinging member swings vertically via the jack lever to pull the needle to the inoperative position. In addition to pushing the needle up into the operating position, the needle is always supported from below by the needle abutment protrusion when pushed up, so the needle does not swing during the knitting movement, and it also prevents the needle from moving between the facing needle selection drums. The interval between increases.

〔Example〕

FIG. 1 is a longitudinal sectional view showing an embodiment of this invention. The needle selection device of the stockinette knitting machine of this invention is equipped with a pair of needle beds 1 facing each other in an inverted V shape, a needle selection drum 2 with unevenness corresponding to the pattern to be made on the surface, and a needle bed. This needle selection drum 2 is located below 1.
a jack lever 4 that contacts the uneven surface of the jack lever 4 and swings about a support shaft 3 at its lower end; a swinging member 6 whose lower end is bendably joined via a connecting portion 5 provided at the upper end of the jack lever 4; The swinging member 6 swings in the vertical direction about a support shaft 7 at the upper end, and has a rectangular needle abutting protrusion 8 connected to it approximately at the center of its upper edge, and a needle insertion opening at the upright tail at its lower end. 9 is provided. This needle selection device is compatible with knitting needles 10 that are longer than conventional ones without a jack, and has a jack lever 4.
The swing member 6 swings through the swing of the knitting needle 10.
When the needle is pulled up to the non-operating position or pushed up to the operating position, the needle touches the protrusion 8.
It is supported and stable.

The needle bed 1 is provided with an inclined needle groove 11 on the upper surface that becomes deeper as it goes downward, and the long knitting needles 10
is inserted so as to be vertically movable and swingable about the pillow part 23 above the groove as a fulcrum.

In the jack lever 4, a coil spring 12 is attached to the lower end of the support shaft 3, and a cam 13 located approximately at the center of the lower edge is in constant pressure contact with the needle selection drum 2. Further, the connecting portion 5 includes a round protrusion 1 at the tip of the jack lever 4.
4 is slidably inserted into a deep recess 15 at the lower end of the swinging member 6, and even when the butt 16 of the knitting needle 10 sinks into the needle groove 11, that is, when it is pulled into the inoperative position. The protruding piece 14 is prevented from coming out of the recess 15.

The swinging member 6 has a needle abutting protrusion 8 that is connected to the knitting needle 10.
The upper edge of the butt 16 is located below the needle lever 4 and is formed so that the lower surface of the needle insertion hole 9 is aligned with the lower surface of the needle insertion hole 9.
When the cam 13 of is placed on the convex surface of the needle selection drum 2,
Accompanying this, the knitting needles 10 are swung upwards, and the butts 16 of the knitting needles 10 reach the operating position in which they protrude from the needle grooves 11 to the uppermost position. The knitting needle 10 is located at the pillow part 2 of the needle groove 11.
3.

In addition, 17 is a cam for knitting needles, 18 is a sinker that swings about the support shaft 19, 20 is a cam for pushing down the sinker, 21 is a cam for pushing up the sinker, 22
is a hook plate that fixes the support shaft 19 to the needle bed 1.

When the needle selection device of the stockinette knitting machine is used, a needle selection drum 2 having unevenness corresponding to the pattern is used, and when the knitting machine starts operating, the needle selection device comes into contact with the uneven surface of the needle selection drum 2. The swinging member 6 swings through the jack lever 4, which swings, and the knitting needles 10 are pushed upward to the operating position or retracted to the lower non-working position. Since the needle abutting protrusion 8 is located below the butt 16 of the knitting needle 10, the cam 17 is attached to the butt 16.
Even if a large external force is applied here, the knitting needle 10
A beautiful stitch can be obtained without any wobbling.

Note that this needle selection device for stockinette knitting machines can also be applied to circular knitting machines.

〔effect〕

As described above, the needle selection device for a stockinette knitting machine according to this invention is provided with a swinging member that is arranged substantially parallel to the knitting needles and swings in the same direction as the up and down movement of the knitting needles. is always supported by the needle abutting protrusion of the swinging member, so it does not swing during knitting operation unlike the conventional example, and since the protrusion is in contact with the butt where the cam acts, it is even more stable. In addition, since a single long knitting needle is used and a swinging member is involved, the needle selection drum can be lowered, so even if the pattern becomes complex and the needle selection drum becomes larger, it can be easily Since there is a sufficient space between the two drums, there is no problem in lowering the knitted fabric A, and there are effects such as the ability to easily create gorgeous and complex patterns.
