Description

[Detailed description of the invention] The present invention relates to a holding structure for attaching a pattern plate of a warp knitting machine. This is an improved pattern holding structure in which a U-shaped sliding member reciprocates in the direction of the knitting needle rows according to the grooves.

Conventionally, a warp knitting machine has a guide shaft formed by fixing a plurality of swinging members, and is equipped with a reed and a pattern plate that are provided on the swinging members through a holding member so as to be able to reciprocate in the direction of the knitting needle row. In,
Especially in multi-reed lace machines that have 40 or more pattern plates, the space occupied by the pattern plates gradually increases in proportion to the increase in the number of reeds, and along with this, the momentum of the fluid replacement group gradually increases. The resulting increase in inertial force has a large effect on the knitting rotation speed, and the slope of the reed at the end becomes nearly horizontal, which affects the relationship between the knitting needle and the knitting yarn threaded through the thread guide rod. There was a strong possibility that this would worsen the situation and cause problems in the organization.

Therefore, the present invention has been devised to solve the above-mentioned problems, and aims to provide a pattern holding structure for a warp knitting machine that can considerably reduce the space for laying the replacement fluid group compared to the conventional method.

Next, a description will be given based on illustrations.

FIG. 1 is a side view showing a reed arrangement in a conventional warp knitting machine, in which 1 is a swinging member, 2 and 3 are guide shafts, 4 is a knitting needle,
A plurality of swinging members 1 are arranged at appropriate intervals in the direction of the four rows of knitting needles, and support parts 5 protruding from the upper part,
6 is fixed to the guide shafts 2 and 3; 7 is a holding member; 8 is a holding member;
9 is a U-shaped sliding member, 9 is a pattern plate, 10 is a thread guiding rod having a thread passing hole at the tip, the thread guiding rod 10 is screwed to the pattern plate 9, and the pattern plate 9 is It is screwed and fixed to the same number of sliding members 8 as the holding members 7, 11.12 is a ground reed, 1
Reference numerals 3.14 and 3.14 are thread guide rods, which are screwed onto the ground reeds 11 and 12, respectively.

In the conventional pattern holding structure described above, two pattern plates 9 are provided in close contact with each other so as to be able to slide back and forth within the sliding groove, and these two pattern plates are attached to the holding member 7 as a set. , usually consists of four pattern plates as one unit, and are arranged consecutively and at regular intervals at the positions indicated by the dotted lines in the figure, forming a state of gathering of the tips of the thread guiding rods called nesting.

Here, the thread guiding rod 13 and the thread guiding rod 10, which are held and fixed to the ground reed 11 and the pattern plate 9 on both sides of the reed arrangement, are aligned with the horizontal line H.
The magnitude of the inclination angles α and β held against the threads is very important in knitting, and the relationship between the knitting needles 4 and the knitting yarn threaded through each thread guide rod, particularly regarding the thread guide rod 13, is important for forming loops. This means that the angle β becomes smaller.
Knitting is performed in a state where the thread guiding rod 11 is closer to the knitting needles 4 in the horizontal direction, and as the knitting speed is increased, this causes problems in knitting such as the generation of fuzz and skipped stitches. In this case, α= 5°, β=25°.

The conventional example shown in Fig. 1 is a multi-reed lace machine that has 2 ground reeds and 50 reeds, and the nesting of the replenisher is such that the first row is 2 sheets per unit, and the next 2nd row is nested. From the 133rd row, there are 12 rows of replacement fluid groups, each consisting of four sheets forming one unit, and including two rows of ground reeds, constitutes the entire reed arrangement.

2 and 3 show a pattern holding structure according to an embodiment of the present invention, 15 is a holding member, and two guide plates 16 and 17 form a set, which are spaced apart above and below the holding member 15. Sliding groove 20
, 21 are provided with sliding members 24, 25 so as to be slidable in close contact with each other, and adjacent sliding grooves 22, 23 are provided with sliding members 24, 25 so as to be slidable in close contact.
6.27 is also slidably provided, the guide plate 16 is provided on the sliding member 24, the guide plate 17 is provided on the sliding member 25, the guide plate 18 is provided on the sliding member 26, and the guide plate 18 is provided on the sliding member 26. Guide plates 19 are screwed to each guide plate 27, and each guide plate 16, 17,
The lengths 18 and 19 are alternately long and short, and the tips are bent in the same direction when the thread guide rod 28 is attached.

Therefore, it is possible to install the four rows of replacement fluid in the same holding member in a state where they are close to each other.

A thread guide rod 28 is attached to each guide plate according to the width of the handle.

1 by these four guide plates 16, 17, 18, 19.
A row of units is constructed.

Fig. 4 shows an example of a reed arrangement employing the pattern holding structure configured as described above. In this case, α'35°, β'=
It is possible to significantly improve the inclination angle to 35° compared to the conventional example.

Note that the first example uses a conventional pattern holding structure.

The present invention is constructed as described above, and two fluid replacement fluids are combined into one
A reed row is formed by attaching two sets of reed arrays to one holding member, and guide plates for attaching thread guiding rods are alternately long and short, and the directions in which the tips of the thread guiding rods coincide. Since the reed is bent, the space for arranging the reed for fluid replacement can be reduced.
As a result, the inclination angle of not only the end fluid replacement but also the ground reed can be made much higher than before, which improves the relationship with the knitting needles during knitting, and also integrates four pattern plates into one holding member. This contributes to the weight reduction of the knitting section, leading to stabilization of the knitting, and has high practical effects, and the structure is simple and easy to process.
