Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a handloom used to manufacture textiles such as kasuri (kasuri), and particularly relates to a mechanism that can adjust the tension of warp threads to a constant level. It is something.

(Prior art) Kasuri and other textiles are manufactured by weaving four types of twisted yarns: warp threads, weft threads, ground warp threads, and ground weft threads that have been dyed in advance based on designs such as flowers and leaves. Therefore, in order to create an accurate pattern on the fabric, it is necessary to weave the four types of twisted yarns without any deviation.

Conventionally, as a hand loom used to manufacture this type of textile, one having a structure as shown in FIG. 3 is known. That is, a horizontal rod 30 is fixed to the rear part of the hand loom B, and the middle of the warp thread is fixed to the horizontal rod 30. A ground vertical receiver 31 is fixed in parallel to the horizontal bar 30 near the horizontal bar 30, and the ground vertical receiver 31
It is adapted to receive the ground warp threads led out from a drum 32 provided below and guide it forward. Here, the ground warp yarn is wound around the drum 32, and the ground warp yarn can be drawn out by rotating the drum 32 as necessary. Further, a thousand windings 33 are provided at the front of the handloom B, and a group of warp threads (warp threads, ground warp threads) guided horizontally from the horizontal rod 30 and the ground warp receiver 31.
The tip is fixed. In addition, approximately in the center of handloom B, there is a pair of healds 3.
4 are provided, and the warp threads and the ground warp threads are inserted through each heald 34, respectively. Each heald 34 can be moved up and down relative to each other by operating a treadle (not shown), thereby dividing the warp threads and the ground warp threads into two groups, upper and lower, and from between them, the weft threads are The weft threads are woven by flying a shuttle (not shown) with a thread. Further, a reed 35 is provided between the heald 34 and the 1000-maki 33, and the weft yarn woven as described above is pressed into the woven fabric by the reed 35. There is. Note that the 1000 rolls 33 can be rotated as necessary, and by this rotation operation, the finished weaving portion is rolled into the 1000 rolls 33.

(Problem to be solved by the invention) When manufacturing textiles such as Kasuri, it is necessary to set the warp threads and the ground warp threads to appropriate tensions, and if the tension settings are not appropriate, the finish will be poor. When the ivy fabric becomes wrinkled, problems arise. By the way, when using the conventional handloom constructed as described above, the worker manually holds down the warp threads and the ground warp threads stretched between the horizontal rod, the ground warp receiver, and the 1000 rolls. , it was determined whether the tension was appropriate based on its elasticity. However, relying on the individual worker's intuition to set the tension based on the feel of the hand, it takes a long time to master the skill, and no matter how much practice the worker practices, the quality of the product can vary considerably. There is a problem that variations occur. In addition, in conventional handlooms, the warp threads and the ground warp threads are fixedly stretched between the horizontal rod, the ground warp receiver, and the 1000 rolls, and the warp threads, the weft threads, the ground warp threads, and the ground warp threads are Since the four types of twisted threads of the ground weft are alternately crossed and woven, the finished part is wavy, and the intersecting part requires longer threads than the straight part, resulting in a non-woven pattern. The tension in the warp threads and the ground warp threads in the part gradually becomes stronger. As the tension of the warp threads and the ground warp threads gradually increases, it becomes difficult to neatly press the woven weft threads into the fabric front, and the dyed parts of the warp threads and the ground warp threads become difficult to press into. Since the positional relationship of the dyed parts applied to the weft weft yarn and the ground weft yarn becomes misaligned, there is a problem in that an accurate pattern cannot be produced on the fabric. Furthermore, twisted yarns such as warp yarns are easily affected by the surrounding humidity. For example, when the humidity is high, if the tension of the warp yarns and the ground warp yarns gradually increases as described above, the warp yarns and the ground warp yarns will The thread gradually stretches. In this case as well, the positional relationship of the dyed portions applied to the warp threads and the ground warp yarns to the dyed portions applied to the weft threads and the ground weft yarns will be misaligned, so it is difficult to create an accurate pattern on the fabric. I can't.

In view of the above-mentioned problems of the prior art, the present invention has been developed to provide a warp thread tension setting method for handlooms that can easily and accurately set the warp thread tension and keep the set tension constant. The purpose is to provide a tension adjustment mechanism.

(Means for Solving the Problem) Therefore, in the present invention, instead of the horizontal rod 30 and the vertical support 31 which were provided in a fixed state in the past, rotatably supported shafts are provided between a pair of left and right mounting frames. a horizontal rod, a vertical support provided parallel to the horizontal rod and rotatably supported between the mounting frames; A first lifting arm is rotatably connected to the end of the horizontal rod, and its base end is pivotally connected to the other mounting frame, and the first lifting arm is rotatably connected to the end of the vertical support via a connecting piece. A device is attached thereto, which includes a second lifting arm movably connected and a weight body that can be attached to any position on the first and second lifting arms.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is an exploded perspective view of a tension adjustment device according to the present invention, and FIG. 2 is an explanatory diagram of the operation of the tension adjustment device.

As shown in FIG. 1, a pair of left and right mounting frames 1a,
A horizontal rod 3 and a vertical support 4 are rotatably supported between 1b. Here, the horizontal rod 3 is provided with a plurality of protrusions 3a along its longitudinal direction,
A part of the vertical thread is wound around the protrusion 3a and fixed thereto. Both mounting frames 1a, 1
The proximal ends of the lifting arms 6 and 9 are pivotally attached to b, respectively. A projecting piece 3b is provided at one end of the horizontal rod 3 in a direction perpendicular to the longitudinal direction thereof, and the base end of the lifting arm 6 is rotatably attached to the projecting piece 3b via a connecting piece 5. freely connected. Thereby, the rotational movement of the horizontal rod 3 is transmitted to the elevating arm 6 via the connecting piece 5 as its elevating and lowering movement. Further, a protruding piece 4a is provided at one end of the ground vertical support 4 in a direction perpendicular to the longitudinal direction thereof, and the base end of the lifting arm 9 is connected to the protruding piece 4a via a connecting piece 8. Rotatably connected. As a result, the rotational movement of the vertical support 4 is transmitted to the lifting arm 9 via the connecting piece 8 as its lifting/lowering movement. In addition, the lifting arms 6 and 9 include
Rectangular weight bodies 11a and 11b are respectively attached to the tips thereof. The weight bodies 11a, 11
b is provided with an insertion ring 12 at its end and center, and the lifting arm 6,
9, the weight bodies 11a, 11b
can be slidably mounted on the lifting arms 6 and 9. In addition, the weight bodies 11a, 11b
A screw hole 13 is bored in the screw hole 13.
By screwing the bolt 14 through the weight body 11
a, 11b can be fixed at arbitrary positions on the lifting arms 6, 9.
Note that marks (not shown) are placed at multiple positions on the lifting arms 6 and 9, so that the weight bodies 11a and 11b can be fixed at appropriate positions depending on the type of fabric. .

The tension adjustment device A configured as described above is installed in the rear part of a handloom. That is, this tension stabilizing device A replaces the horizontal rod 30 and ground vertical support 31 that were fixedly provided at the rear of the conventional hand loom B, and the other structure is the same as that of the conventional hand loom B. (See Figure 3).

Next, the operation of this embodiment will be explained.

As shown in FIG. 2, first, the lifting arms 6, 9
The weight bodies 11a and 11b are respectively fixed at appropriate positions on the top. Next, the ground warp yarn 17 led out from the drum 32 is received by the ground warp receiver 4, and the tip of the ground warp yarn 17 and the tip of the warp thread 18 are fixed in a 1,000-roll 33. In this state, when the 1000 rolls 33 are rotated, the ground warp thread 17 is pulled forward and the ground warp receiver 4 is tilted forward (arrow A), as shown in FIG. 2a. This tilting motion of the vertical receiver 4 is transmitted as a rising motion to the lifting arm 9 via the connecting piece 8 (arrow B). As previously mentioned,
Since the weight body 11b is attached to the lifting arm 9, a downward force (arrow C) is acting on the lifting arm 9, and a force corresponding to the downward force acting on the lifting arm 9 is applied to the ground warp thread 17. Acts as tension. Next, the middle of the vertical thread 18 whose tip is fixed to the 1000-maki 33 is fixed to the protrusion 3a provided on the horizontal rod 3. In this state, when the 1000 rolls 33 are further rotated, the vertical threads 18 are pulled forward, causing the horizontal rods 3 to tilt forward (arrow D), as shown in FIG. 2b. This tilting motion of the horizontal rod 3 is transmitted as a rising motion to the lifting arm 6 via the connecting piece 5 (arrow H). As mentioned above, since the weight body 11a is attached to the lifting arm 6, a downward force (indicated by the arrow) acts on the lifting arm 6, and a force corresponding to the downward force acting on the lifting arm 9 is applied. It acts as tension for the warp threads 18. Vertical thread 1 as above
8 and the ground warp yarn 17 can be easily and accurately set.

After setting the tension of the warp threads 18 and the ground warp threads 17 as described above, the warp threads, the weft threads, the ground warp threads, and the ground weft threads are woven so that they intersect alternately. go. When the weft weft yarn and the ground weft yarn are woven, the finished weave requires longer yarns than the straight line at the undulating and intersecting portions, so the warp weft yarn 18 and the ground warp yarn 17 are pulled forward. However, by following this and tilting the horizontal rod 3 and the ground warp receiver 4 forward, the warp threads 18 and the ground warp threads 17 are sent forward, and
As the elevating arms 6 and 9 further rise, the warp threads 18 and the ground warp threads 17 rise due to the above-mentioned reason.
The tension is maintained at the initial setting value. Therefore, the woven weft thread and ground weft thread can be press-fitted into the fabric in the same manner.
The positional relationship between the dyed portions applied to the warp weft yarns 18 and the ground warp yarns 17 and the dyed portions applied to the weft weft yarns and the ground weft yarns does not shift. Note that when the ambient humidity is high, the vertical threads 18, etc. tend to stretch, so the tension applied to the vertical threads 18, etc. must be reduced. The positions of 11a and 11b may be adjusted and attached slightly closer to the proximal end.

(Effects of the invention) The present invention has the above configuration, so that
Since you can easily and accurately set the tension of warp threads, it does not take much time to learn how to do it, and
It has the excellent effect that there is no variation in the quality of the product no matter who weaves it. Furthermore, even if the warp threads are stretched as they are woven, the tension of the warp threads is automatically maintained at a constant value and does not change under any circumstances. As a result, the woven weft threads can be press-fitted into the fabric front in the same manner, and the positional relationship of the dyed parts applied to the weft threads to the dyed parts applied to the warp threads will not shift. It has the excellent effect of making it possible to easily create accurate designs on textiles.
