Description

[Detailed explanation of the idea] The present invention relates to a hanging device for threading jacquard.

Weaving factories that produce textiles using tapets or dobies generally have low ceiling heights, and even though they tried to shift to jacquard looms that can weave complex patterns in response to trends in the textile market, the ceilings were low. Installation may not be possible. That is, as shown in FIG. 8, in a jacquard loom, when the jacquard 1 is installed in the forward and backward direction and the jacquard 1 is installed in the forward and forward direction, the bending angle θ1 of the thread Y at the batten 2 portion is too large. When the size becomes smaller, due to frictional contact between the thread thread and the holes in the batten,
In general, the angle θ1 is
The temperature is set at 140℃~150℃. Therefore, the distance or height H1 from the batten 2 to the harness guide 3 at the bottom of the jacquard is 1.5 to 2.5 m, and when adding the loom height S or the jacquard height, etc., the distance from the floor to the ceiling is 4.5 to 2.5 m. It can reach up to 5.5m.

In order to install a jacquard loom, which requires such a ceiling height, into a factory that already has tappet and dobby machines, the building must be renovated.

The purpose of the present invention is to solve the above-mentioned problems, and in particular, to provide a hanging device that can reduce the height between the harness guide 3 and the batten 2, which occupies most of the height of the jacquard loom, as much as possible. It is.

That is, the present invention provides one or more stages of auxiliary harness guides between the harness guide and the battens, and guides the thread hanging down from the jacquard by bending it to the guide portion of the auxiliary harness guide.
In addition, an auxiliary harness guide is provided in which the bending angle of the thread is approximately the same as the bending angle θ1 in the conventional suspended state at each bending portion.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, a hanging device 6 according to the present invention is installed between a jacquard 1 installed on a ceiling frame 4 and a loom 5.

That is, the brackets 7, 7 are suspended and fixed at the center of the weave width W of the frame 4, and the auxiliary harness guide mounting shafts 10, 11 are fixed at appropriate positions of the brackets 7, 7 between the harness guide 8 and the batten 9. , the axis 1
Depending on the weaving width, one or more guides 0 and 11 are attached, and in the case of multiple guides, they are attached at appropriate intervals in the vertical direction, and the auxiliary harness guides 12a, 12b and 13
One ends of a and 13b are supported by shafts 10 and 11. That is, one set of auxiliary harness guides 12a and 12b,
13a and 13b become one set, and in the case of this embodiment,
Auxiliary harness guides are provided on the upper and lower levels.

In addition, the auxiliary harness guides 12a, 12b,
Support rods 14a, 1 are provided at the other ends of 13a, 13b.
The lower ends of the rods 4b, 15a, and 15b are connected, and the upper end of each rod is attached to the frame 4 so that its attachment position can be adjusted. That is, for example, each rod 14a, 14
Holes 16a, 16b, 16c, 16d for bolts are drilled at multiple positions on the upper end of the frame 4 side, and the rods 14a, 14b are connected by bolts 17a, 17b, etc. installed at fixed positions on the frame 4 side. ，
15a and 15b are screwed together while adjusting the height. That is, by changing the attachment position of the rods 14a, 14b, 15a, 15b to the frame 4, the angle of inclination of the auxiliary harness guides 12a, 12b, 13a, 13b is changed, and the angle of inclination of the auxiliary harness guides 12a, 12b, 13a, 13b is changed. This adjusts the bending angle of the thread.

Examples of the auxiliary harness guides 12b and 13b are shown in FIGS. 3 to 6. That is, the auxiliary harness guide 12b shown in the third and fourth figures shows the upper guide 12b in FIG. 1, and the same ones are used on the left and right sides. In FIGS. 3 and 4, a wire rod 20,
21 are fixed in a grid pattern, and a large number of guide sections 22 through which the thread passes are formed in an orderly manner, and each section 22
One or more threads are passed through the thread. In place of the above-mentioned auxiliary harness guide 12b, a section 2 is provided in a plate-like body.
2 or a thin rod with the same number of holes as 2
Of course, it is also possible to form the parts 0 and 21 of a wear-resistant material such as ceramic.

The auxiliary harness guide 13b shown in FIGS. 5 and 6 is an example of the lower guide 13b in FIG. shaft 25,
25, and similar to the above, a large number of sections 28 for threading guides are formed using thin rods 26 and 27, and the width t between the guide frames 23 and 23 is equal to the width between the frames 18 and 19 of the upper guide. It is smaller than T.

Therefore, when the auxiliary harness guides 12 and 13 are provided in two stages, upper and lower, and the thread is suspended in a sequential manner, the refraction angles β1, β2, . . . α2 as shown in FIG. Each thread is suspended so as to reach a fixed position on the lowermost batten 9.

The above refraction angle will be explained with reference to FIG.
Note that the auxiliary harness guides 12a and 12b are denoted by 12, and the auxiliary harness guides 13a and 13b are denoted by 13. When the harness guide 3 is provided at the conventional height H and no auxiliary harness guide is provided, the thread Y1 hanging down from the jacquard is first bent at an angle α1 at the harness guide 3, and then bent at an angle α2 at the batten 9 position. and is connected to the lower heald. Generally, the angles α1 and α2 are set to values within the range of 140°C to 150°C. When the harness guide 3 is simply lowered to the solid line position 8, the angle α1',
Both α2' are smaller than angles α1 and α2,
The angle becomes steep, frictional resistance increases, and threading is damaged.

On the other hand, as in the present application, the auxiliary harness guide 12,
13, the refraction angle β at the harness guide 8
1. The refraction angle α2 at the eye plate 9 is α1′,
In particular, in the case of FIG. 7, the thread is threaded directly below the harness guide 8 on a line L1 parallel to the thread Y1, that is, threaded between the harness guide 8 and the upper auxiliary harness guide 12. Y2 is located, and threading Y3 between the lower guide 13 and the batten 9 is
If it is located on line Y1, α1=β
1, α2=α2, which is the same as the conventional hanging angle state. Furthermore, auxiliary harness guide 1
Regarding the refraction angles β2 and β3 occurring at points 2 and 13, the refraction portions 12c,
13c, or the auxiliary harness guide 1 can be formed such that the refraction angle at any refraction part is approximately equal to the maximum refraction angle in the conventional standard suspended state, and the auxiliary harness guide 1 widens as it goes downward from the jacquard.
2, 13 can be installed.

In a jacquard loom having the above-described hanging device, when a weaving operation is performed with the hanging device in the state shown in FIG. When the harness guide 8 and auxiliary harness guide 1 are pulled up,
2, 13 and the thread passing through the perforated plate 9, the heald 29 is pulled up against the spring arrow 31 whose one end is fixed to the machine base 30, and the warp thread threaded through the heald 29 is pulled up and the upper side Form an opening.
The pulled thread is lowered by the spring 31, and the warp thread is opened.

In this case, the threads Y2 to Yn are bent and pulled up and lowered by the auxiliary harness guides 12 and 13, but the bending angle (Fig. 7, β1, β2, β
3. Since both angles α2) are set to the conventional standard hanging angles (140°C to 150°C), there is little resistance due to refraction and smooth movement is possible. In addition, the outermost thread Y2 in FIG.
The refraction angle at the bending part of Yn is the smallest, and the further inside the thread Yr is threaded, the larger the refraction angle becomes, and the resistance due to refraction becomes smaller.

As described above, according to the present invention, an auxiliary harness guide for guiding threading is provided between the harness guide at the bottom of the jacquard, which guides the threading that moves up and down by the jacquard, and the batten at the top of the loom, so that the mounting position of the jacquard is In other words, the distance between the harness guide and the batten can be shortened, and the jacquard can be installed at a low position while maintaining the refraction angle of the hanging thread at the conventional standard angle, making it possible to reduce the distance between the harness guide and the batten. Jacquard looms can be installed in textile factories with low ceilings without modifying the building. For example, the distance h in Figure 1 varies depending on the cloth, but the conventional height (H in Figure 8) is 1.5 to 2.5 m, and the height to the ceiling is 4.5 to 2.5 m.
In the case of 5.5m, in this invention, even if the weave width is the same,
If the height h is H/2, then h = 0.75 to 1.25 m, and the height to the ceiling is also 3.75 to 4.25 m, and in some cases, 3.5 m.
m or less. In addition, by reducing the height between the harness guide and the batten, the length of the thread can be shortened, reducing the overall amount of thread used (over 1,000 threads) and saving thread. can.
