Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a latch guard, and particularly to a latch guard for a sock knitting machine.

[Conventional technology]

Generally, when knitting socks on a sock knitting machine, plating is performed for the purpose of knitting different yarns on the front and back of the socks to increase the added value of the socks. That is, a non-stretchable thread is used as the front thread, and a stretchable thread is used as the back thread.

When knitting the heel, toe, etc., generally the long butt needle on the half circumference of the cylinder (on the opposite side of the cylinder keyway) is moved to the non-knitting level (top of the center cam) with a "raise switch cam". ”
The needle is raised by the needle, and the remaining short needle needle is used to rotate the cylinder in forward and reverse directions to reduce or increase the number of stitches by raising the needle and lowering the needle. Further, in this case, the front yarn and the back yarn are supplied from the yarn path to the yarn supply receiving portion of the latch guard.

[Problem to be solved by the invention] Conventionally, as mentioned above, since the cylinder rotates forward and backward, when the front thread and back thread are fed to the thread supply receiving part of the latch guard, the front thread and back thread are There is a risk that the threads may become entangled, and if they become entangled, plating defects may occur, resulting in defects such as "tagging" in the heel area, etc.

Therefore, in the present invention, when knitting the heel etc., the front thread and the back thread do not get entangled,
To provide a latch guard that does not produce defective knitted socks.

[Means to solve the problem]

In order to achieve the above object, the latch guard of the present invention has a latch guard in which the front yarn and the back yarn from the yarn path slide into contact with the outer surface of the yarn supply receiving section, and the front yarn and the back yarn are brought into close contact with the outer surface of the yarn supply receiving section. A pair of left and right thread separation protrusions are provided to separate the threads at the same time.

[Effect]

At the yarn separation protrusion, the front and back yarns from the yarn path are separated near the yarn supply and receiving section, so when knitting the heel part, the cylinder rotates forward and backward. Even if the front thread and the back thread are not intertwined with each other.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a latch guard 1 according to the present invention, and this latch guard 1 is provided with a thread separation protrusion 4 on the outer surface 3 side of a thread supply/reception part 2. Further, the thread separating protrusions 4 are provided in pairs on the left and right sides as shown in FIG.

As shown in FIG. 2, the latch guard 1 consists of a ring body, and near the thread supply/reception part 2, there are
A thread path 5 is provided, and a front thread 6 and a back thread 7 are delivered from the thread path 5.
is supplied to the yarn supply receiving section 2, and each front yarn 6 and back yarn 7
enters latch guard 1. Then, the front thread 6 and the back thread 7 are knitted by needles (not shown) in the latch guard 1.

Here, the front thread 6 is composed of a thread that does not have elasticity, and the back thread 7 is, for example, a core thread made of polyurethane or the like, and a thread-like body of nylon or the like wound around the core thread. , and has elasticity.

As shown in FIGS. 3 and 4, the yarn path 5 has a circular front yarn supply section 9 and an arcuate back yarn supply section 10 opened at the distal end surface 8, and the yarn As shown in FIG. 2, the front yarn 6 on the front side of the path 5 comes out of the front yarn supply section 9 through the front yarn guide port 11 opened at the upper surface of the tip and is supplied to the yarn supply receiving section 2. Further, the back thread 7 guided to the back thread guide section 12 of the thread path 5 comes out from the back thread supply port 10 and is supplied to the thread supply receiving section 2.

Further, as shown in FIGS. 3 and 4, the yarn separating protrusions 4 are arranged at predetermined pitches, so that the surface yarn 6 from the yarn path 5 slides into contact with the lower end while being locked in the yarn path. The back thread 7 from 5 is locked and slid into contact with the upper end. Therefore, the front yarn 6 and the back yarn 7 are in a separated state in the vicinity of the yarn supply/reception section 2. In other words, even when the front thread 6 and the back thread 7 are tensioned to the right as shown in Figure 3, the front thread 6 and the back thread 7 are applied to the left as shown in Figure 4. Even when tension is applied, the front thread 6 and the back thread 7 are kept separate.

That is, the front yarn 6 and the back yarn 7 do not become entangled in the vicinity of the yarn supply/reception section 2, and defects such as "tagging" do not occur.

Next, FIG. 5 shows a modification of the thread separation protrusion 4,
In this case, a groove 13 whose lower end is open downward is formed, and the surface yarn 6 slides into the groove 13 while being locked therein.

Note that the present invention is not limited to the illustrated embodiment, and the design may be changed without departing from the gist of the present invention. For example, the thread path 5 may be an existing one, and there is no need to use a special one. There are many different types that can be used. Further, the thread separating protrusion 4 may have any shape other than those shown in FIGS. 1 and 5 as long as it holds the front thread 6 and the back thread 7 in a separated state. Furthermore, the thread separation protrusion 4
may be formed by fixing a separate member to the thread supply section 2 by welding or the like, or may be formed integrally.

[Effect of idea]

Since the present invention is configured as described above,
This produces the following effects.

In the vicinity of the yarn supply and receiving section 2, the front yarn 6 and the back yarn 7 from the yarn path 5 do not become entangled during knitting of the heel of the sock, thereby preventing plating defects and creating a so-called "" Does not cause defects such as sagging.

In addition, a pair of yarn separation protrusions 4, 4 are provided on the yarn supply receiving portion 2.
Since it is only necessary to provide a , the manufacturing thereof is simple and has the advantage of not increasing costs.

Claims (1)

[Scope of utility model registration request] A pair of left and right threads are formed on the outer surface 3 side of the yarn supply receiving section 2 so that the front thread 6 and the back thread 7 from the thread path 5 come into sliding contact and separate the front thread 6 and the back thread 7 in the vicinity of the yarn supply receiving section 2. A latch guard characterized in that thread separation protrusions 4, 4 are provided.
