63271号）。<Prior Art> In the conventional warp thread shedding device in a circular loom, one end of a swing lever for operating a heald heald is directly engaged with a cylindrical cam provided on a main shaft, and the swing lever is pivotally supported at an intermediate fulcrum. The main structure is such that the other end is connected to the heald heddle (3) (Japanese Patent Publication No. 40-3319, Japanese Patent Laid-Open No. 50-39).
63271).
〈考案が解決しようとする問題点〉 このような円筒カムと揺動レバーを直接係合させた構造
であると、揺動レバーの中心には直角方向の荷重が加わ

However, the service life of the bearing is shortened, and the engaging contact surface between the cam and the rocking lever is worn. This has been a problem to be solved especially when weaving a large-sized tubular fabric.

したのである。<Means for Solving Problems> Therefore, in the present invention, the operation of the heald heddle (3) is operated by the cylindrical cam (2) provided on the loom main shaft (1) through the rocking lever (4). In a circular loom that opens vertical warp yarns, a slide shaft (5) is provided parallel to the main shaft (1), and a slider block (6) is loosely inserted therein, and one of the slider blocks (6) is inserted into the cylinder. The above-mentioned difficulty is solved by adopting a structure in which one end of the swing lever (4) is locked to the slider block (6) while being engaged with the cam (2).

The rotation of the slider block causes the slider block (6) to move up and down, whereby the swing lever (4) swings to open the heald heddle (3).
At this time, the slide shaft (5) absorbs the force in the direction perpendicular to the axis, that is, the rotational direction of the cylindrical cam (2), and the swing lever (4) simply swings the slider block (6) vertically. Only the power of will be added.

(3b)に設けたピン(12)を挿通した構造である。In such a circular loom, in the present invention, the main shaft (1) has two
The cylindrical blocks (2a) and (2b) are provided, and the slide shaft (5) is provided in parallel with the main shaft (1). The slider blocks (6a) and (6b) are vertically inserted into the slide shaft (5), and the slider block is inserted.
The cam rollers (13a) and (13b) of (6a) and (6b) are connected to the cylindrical cam (2a) (2
The rail of b) is sandwiched from above and below, and a guide groove (14) of a pin (15) is provided on the opposite side of the slider blocks (6a) and (6b). Guide groove (14) of slider block (6a) (6b)
One end of the swing levers (4a) and (4b) is locked to each of the above. With this locking structure, a pin (15) is projected on both sides of the ends of the rocking levers (4a), (4b), and this pin (15) is inserted into a guide groove (14) and locked. In the case of such a locking structure, when the rocking levers (4a) and (4b) are in the horizontal direction, the pin (15) is at the deepest side of the guide groove (14) and the rocking levers (4a) and (4b) When is inclined, it moves so that it is near the exit of the guide groove. The swing levers (4a), (4b) are provided with a spindle bearing (10) at an intermediate fulcrum. Swing lever (4a) (4b) and heald heddle (3a) (3
b) is connected to the guide plate (11) at the end of the swing levers (4a) (4b).
Wear the heald heddle (3a) in the slot provided in it.
This is a structure in which the pin (12) provided in (3b) is inserted.

全体的に軽量かつ低コスト化を達成できた。As described above, the slide shaft (5) is provided, and the structure in which the cylindrical cam (2) and the swing lever (4) are linked via the slider block (6) loosely inserted in the slide shaft (5) Because the force in the direction perpendicular to the axis, that is, the direction of rotation of the cylindrical cam (2) is absorbed by 5), the spindle bearing (10) may be smaller and lighter than the conventional one, and the swing lever
The strength of (4) is not required to be as high as the conventional one,
We were able to achieve overall lightweight and low cost.
