[Detailed Description of the Invention] The present invention relates to a twilling device, and its object is to provide a device with a simple structure that can heddle warp threads by simple manual operation.

The device of the present invention has first, second, and third rotary plates installed at both ends and an intermediate portion of a long machine frame so as to be rotatable concentrically, and the first rotary plate and the second rotary plate are A rotation guide frame is formed by interposing an interlocking mechanism and connecting a plurality of guide rods across the first rotary plate and the third rotary plate, and the operating ring and the operating hand are respectively slid on the guide rods of the guide frame. Two long finger levers are protruding from the operating ring and the operating hand at equal intervals on the circumference, and the operating ring and the operating hand each pass through the third rotating plate and engage and disengage from the second rotating plate. , is characterized in that a large number of heald plates each having a plurality of thread holes in the long finger levers are arranged in parallel in a skewered manner.

The first embodiment of the present invention will be described with reference to the drawings.
In the figures, A is a machine frame, 1 is a first rotating plate, 2 is a second rotating plate, 3 is a third rotating plate, 4 is an operating ring, 5 is an operating hand, and 6 is a heald plate.

The machine frame A is a horizontally elongated underframe, with a bearing 11 on its left end and a bearing 12 on its right end, with a first rotary plate 1 and a second rotary plate 2 attached to each bearing 11 and 12. Each is rotatably supported on a shaft and has a receiving ring 1 in the middle part.
2 is raised up, and the third rotary plate 3 is rotatably fitted and installed on the receiving ring 13.

In the machine frame A, the space between the rotary plates 1 and 3 on the left half serves as an operating section, and the space between the rotary plates 3 and 2 on the right half serves as a yarn running section for running the warp yarns B orthogonally.

The rotating plates 1 and 2 are interlocked with their rotating shafts 1' and 2' via chains 14 and 14' and an interlocking shaft 15,
The rotary plate 2 is made to rotate in the same direction as the rotation of the rotary plate 1.

A core shaft 16 is provided at the center between the rotating plates 1 and 3, and guide rods 17, 17', 18, 18' are provided in parallel on the outer periphery of the core shaft 16, respectively, and these members 1, 2, 16, 1
Rotating guide frame 10 by 7, 17', 18, 18'
Configure.

Through holes 20a, 20b, 20c, and 20d are opened in the third rotating plate 3 at equal intervals on the same circumference.

The rotation guide frame 10 has its guide rods 17, 17'.
The annular operation ring 4 penetrated by the guide rod 1
7, 17', and the operating hand 5, which is penetrated by the guide rods 18, 18' and the core shaft 16, is slidably attached along the guide rods 18, 18' and the core shaft 16.

The operating hand 5 has a substantially square outer shape, and the operating ring 4
A window hole 7 is formed inside so that the operating hand 5 can pass through.

The operation ring 4 has a long finger lever 8 on one side of the rotating plate 3.
a, 8b are protruded at symmetrical positions equidistant from the center and passed through the through holes 20a, 20b of the rotary plate 3, and the operating hand 5 is also provided with long finger levers 8c, 8d on one side of the same side, at equal distances from the center. They are provided protrudingly at symmetrical positions and penetrate through the through holes 20c and 20d of the rotary plate 3.

The long finger levers 8a, 8b, 8c, and 8d are arranged on the same circumference at 90 degree intervals.

The tips of the long finger levers 8a, 8b, 8c, and 8d are located near the rotary plate 3 when the operating ring 4 and the operating hand 5 are positioned at the left extreme, and when positioned at the right extreme, the tips of the long finger levers 8a, 8b, 8c, and 8d are located near the rotating plate 3. Insert and lock into the through hole.

A large number of heald plates 6, 6, . . . are freely inserted into and removed from the long finger rods 8a, 8b, 8c, 8d.

The heald plate 6 is a thin plastic plate in the shape of a regular quadrilateral, and the long finger rods 8a, 8b, 8 are attached to the four corners of the heald plate 6.
Insertion holes a, b, c, and d are opened to pass through holes c and 8d, and thread passing holes a', b', c', and d' are opened at positions equidistant from the holes toward the center.

The long finger rods 8a, 8b, 8c, 8d are the heald plates 6...
The heald plate 6 is inserted into each of the holes a, b, c, and d of...
are suspended in parallel, and when the operating ring 4 is moved to the left, the long finger levers 8a and 8b come out of the heald plate 6..., and when the operating hand 5 is moved to the left, the long finger levers 8c and 8d slip out from the heald plate 6...

During the weaving operation, one or all of the long finger levers 8a, 8b, 8c, and 8d are inserted into the heddle plate 6 for heald operation.

The four warp threads B are made into sets A, B, H, and D, and the threads A, B, H, and D of the set are passed through the thread holes A', B', H', and D' of the heddle plate 6. Insert the thread into the running state.

The above device performs a heddle operation in which the rotary operation frame 10 is rotated 8 frames in the same direction at 45 degrees as shown in FIGS. 6 to 13, and then rotated 8 frames in the opposite direction to the same direction. The weft is repeatedly run into the heddle space for each frame, and when the operation frame 10 is rotated, the long finger rod 8 intersects with the warp yarns A, B, C, and D.
a, 8b or 8c, 8d as operating ring 4 or operating hand 5
By moving the heald plates 6 to the left, the heald plates 6 are alternately inserted into and removed from the heald plates 6, so that frame-by-frame feeding of the heald plates 6 is not hindered.

Since the present invention is constructed as described above, heald work can be performed by frame-by-frame feeding operation of rotating the rotating operation frame to a predetermined angle while inserting and removing the operating ring or operating hand from the heald plate, and this operation can be performed manually. The present invention is extremely simple, and furthermore, it is possible to provide a device with a simple structure and low cost by simplifying the shape of the heald plate and reducing the weight.

Thus, the intended purpose can be achieved.
