Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a sawko shedding device for a handloom, which opens the sawko by operating a threshing device.

(Conventional technology) To explain the structure and function of a conventional handloom, the fifth
The figure shows a plain weave structure woven with 14 warp threads and 8 weft threads.
This shows an example of weaving using a hand loom with two sokos. First, the warp threads are passed through the winding section _K1 at the rear of the handloom, over the support rod _S1 fixed to the main body, and threaded through the heddles L at the front of the handloom, one at a time, and then Two warp threads are simultaneously threaded through the reed feathers of the reed beating device b and stretched between them and the support rod _S2 .

In this state, when stepping on stepping stones T ₁ and T ₂ alternately, the socos connected to them move in the opposite direction up and down, and the warp threads threaded through the socos open up and down, opening the shed through which the shuttle a passes. make. At this time, the shuttle a is thrown from one side of the shed to the other to thread the weft threads and intertwine them with the warp threads. Next, the treadles T ₁ and T ₂ move up and down in the opposite direction from before, and when the two sets of open warp threads (upper and lower) are aligned into one piece when the shed is closed, the threshing device b is tilted forward and the weft threads are set appropriately. Press it to the right position to completely intertwine with the warp threads. As the treadle continues its movement and is in the exact opposite position from the beginning, the warp threads also change their upper and lower positions and open. At this time, the shuttle a is thrown back to the opposite side and the weft thread is passed through. In the same manner as described above, the beating device is tilted forward and the weft is pressed.

By repeating such movements, the warp and weft threads are appropriately intertwined and woven.

The woven cloth is wound up in the winding section _K2 , and warp yarns are sent out from the rear winding shaft _K1 in accordance with this winding.

(Problem to be solved by the invention) However, in the above-mentioned handlooms, the opening movement of the shed by the soko is performed by stepping on the stepping stones T ₁ and T ₂ , and for this reason, generally It is unsuitable for handicrafts, as it is often operated while sitting on a tatami mat.

In addition, there were drawbacks such as the necessity to continuously perform operations such as stepping on the stepping stones _T1 and _T2 , inserting the shuttle a into the shed, and inverting the threshing device b.

(Means for Solving the Problems) In order to solve the above problems, in this invention, two sawko suspensions are connected to each other, and both ends of the sawjers are rotatably pivoted to the loom frame of a handloom. In addition to being fixed to the receiving part, a swinging plate is provided on the saw socket, and below the swinging plate there is an operating rod with an operating piece of the swinging plate rotatably pivoted to the tip thereof, which can be raised and lowered. At the same time, an interlocking rod of a hand loom's threshing device is connected to the operating rod, and the operating lever is connected to one end of the lower surface of the rocking plate with the tip of the operating lever when the operating lever is raised. The present invention proposes a soko shedding device for a handloom, which is equipped with a guiding device that pushes up the other end of the lower surface of the rocking plate when the operating rod moves up the next time.

(Function) This invention is constructed as described above, and the interlocking rod raises the operating rod by operating the threshing device. When the operating rod is raised, the operating piece pivoted at the tip of the operating rod is swung forward or backward by the guidance device, and its tip pushes up one end of the lower surface of the rocking plate. The soko receiver rotates in one direction, opening a shed made up of two sawkos.

Next, when the interlocking lever lowers the operating lever by operating the threshing device, the tip of the operating piece leaves the lower surface of the swinging plate to return the swinging plate to its original position, thereby closing the shed.

Furthermore, when the operating rod is raised again by operating the thrashing device, the operating piece pivotally attached to the tip of the operating rod is caused to swing in the opposite direction to the previous raising by the guiding device, and the tip of the operating piece pivots in the opposite direction to the direction in which it was raised the previous time. The other end of the lower surface of the moving plate is pushed up, which causes the sawko receiving shaft to rotate in the opposite direction from the previous time, opening the shed made up of the two sawkos.

As described above, according to this invention, the opening movement of the saw can be performed by operating the threshing device.

(Example) This invention will be explained below based on the illustrated example.

On the other hand, a swing plate 11 is attached to one shaft part of the soko receiver 8a, and an operating rod 12 is vertically installed inside the central column 4 that supports the shaft part so as to be movable up and down. is provided with an operating piece 12a whose base end is rotatably pivoted to the operating rod 12, and when the operating rod 12 is raised, the tip of the operating piece 12a is formed on the lower surface of the swing plate 11 in the opposite direction. Either of the inclined surfaces 11a, 11b is pushed up to swing the soko receiver 8a in one direction or the opposite direction.

Further, an interlocking rod 13 of the shading device 7 is connected to the lower end of the operating rod 12.

In this embodiment, the interlocking rod 13 is an L-shaped rod 13a.
The L-shaped rod 13a is composed of a connecting rod 13c which is pivotally connected with a pin 13b, and the lower end of the operating rod 12 is placed on one end of the L-shaped rod 13a.
A long hole 13d is formed at one end of the connecting rod 13c, and a pin 14 provided at the lower end of the threshing device 7 is inserted into the long hole 13d.

Next, the beating device 7 is tilted backward to press the weft to an appropriate position to completely intertwine with the warp.

By tilting the threshing device 7 backward as described above, the connecting rod 13c is pulled by the pin 14 inserted into the elongated hole 13d, and accordingly, the L-shaped rod 13
a is operated to lower its end, and the operating rod 12 is lowered accordingly. When the operating rod 12 descends, the inductor 17 pivotally attached to the operating piece 12a also descends.
The inductor 17 tilts in the opposite direction, and the operating piece 12a rests against the guide member 19b and is in a lowered state (FIG. 3c).

When the threshing device 7 is raised forward again, the operating rod 12 rises as before, but this time the operating lever 12
a rises in accordance with the inclination of the guide member 19b, and its tip pushes up the inclined surface 11b formed on the lower surface of the rocking plate 11, causing the saw holder 8a to rotate in the opposite direction to the previous direction. This result Soko 9
a descends, and soco 9b rises to open the shed (Fig. 3 d).

When the shed opens, the shuttle is passed through the shed in the opposite direction from the previous time, intertwining the weft with the warp and weaving. The woven material is wound up in the winding section 5b.

(Effects of the invention) In summary, according to this invention, when the napping device is tilted forward to complete the interlaced state of the weft and warp threads, the shed formed by the saws 9a and 9b closes, and the napping device When standing up backwards, the shed can be opened, and therefore weaving can be carried out without the need for the conventional operation of opening the shed by stepping on a treadle.
In addition, the Soco 9
