Description

[Detailed explanation of the invention] The present invention relates to a top and bottom split type hand loom. This relates to a split type handloom loom.

A handloom has a distaff at one end and a cloth winding bar at the other end, and the warp threads are stretched between them, and the warp threads are guided through the threads in the middle, and every other or every other warp thread is alternately threaded by the threads. The weft is guided through a shuttle between the two, and the warp is raised and lowered alternately to weave it into a cloth.

Conventionally, such handlooms have used a single-plate sill with alternating slits and small holes for passing a large number of threads through.

Therefore, when attaching yarn etc.
This method has the drawback that each yarn must be passed through the slit and the small hole, making the process extremely troublesome.

The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and its purpose is to provide a top-and-bottom split type handloom loom that is structured so that yarn, etc., can be attached extremely easily. There is.

In order to achieve the above-mentioned purpose, the present invention uses a split type that is divided into upper and lower halves, so that a large number of threads can be attached extremely easily without passing the threads through small holes or slits. A new structure was adopted.

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

The handloom designated by reference numeral 1 in the figure has a base 2. A thread winding rod 4 which can be rotated by a dial 3 is horizontally suspended at one end of the base 2, and a cloth winding rod 5 is rotatably mounted at the other end. It is freely suspended horizontally.

This cloth-wrapped rod 5 is rotated by a dial 6.

The base 2 has a pair of left and right support frames 7, 7, and a bracket 8, which also serves as a reel, is attached to the support frames 7, 7 at a position closer to the spool pin 4 so as to be movable up and down and back and forth.

As shown in FIGS. 2A and 2B, the cover 8 has a vertically divided structure, and consists of a lower half 9 and an upper half 10.

The lower half 9 has a substantially U-shape with an upper opening, and has left and right arms 9a and 9b.

One end of the upper half 10 is rotatably supported on the upper end of one arm 9a via a shaft 11.

A long hole 10a is formed in the free end side of the upper half 10, and the long hole 10a bends in an L-shape toward the side, and at a position opposite thereto, near the upper end of the other arm 9b, the other arm 9b moves in the horizontal direction. A stop 12 that can be used is attached.

Further, the upper ends of the left and right arms 9a, 9b are divided into two parts in the front-rear direction, forming a gap 9g, and the left and right ends of the upper half part 10 are structured to fit freely into this part. ing.

Therefore, if the upper half 10 is rotated and fitted to the upper end of the arm 9b, and the stopper 12 is moved from the vertical part of the L-shaped lR10a toward the horizontal part, the lower half 9 and the upper half The part 10 can be easily combined and integrated.

Near the upper ends of the left and right arms 9a, 9b, substantially triangular protrusions 9c are formed symmetrically with the lower sides horizontal, and the lower sides of these protrusions 9c are recesses 9d. Approximately 1/2 of the projection 9c is located below the recess 9d.
A rectangular protrusion 9e is formed with a protrusion amount of approximately
, 7 is approximately the same width.

Further, projections 9f are formed on the lower side of the projection 9e and at the lower end of the lower half portion 9, respectively.

By the way, comb-tooth-shaped parts 13 and 14 are integrally formed in the lower half part 9 and the upper half part 10, respectively, so as to face each other.

These comb-teeth-like portions 13 and 14 are composed of elongated protrusions 13a and 14a that are formed to face each other one-to-one, and each protrusion 13a, 14a alternately complements the opposing one. It is configured to be matched against each other.

The center of the upper end of the protruding portion 13a of one of the comb-like portions 13 is located at the third
As shown in the enlarged view in FIG. A, each is divided into two parts, and a U-shaped groove 13b is formed.

The depths of these grooves 13b are exactly the same, but the two protrusions 13c, 13c formed across the groove 13b have stepped portions 13d alternately formed on opposite sides of the adjacent protrusions 13c. .

That is, as is clear from the figure, the protruding pieces 13c*13c
The thickness of each protrusion 13a is 172t''
are cut out alternately on opposite sides of the front and back.

A slit portion 13e for threading is formed between each of the protruding portions 13a, 13a.

On the other hand, the protruding parts 14a of the upper half part 10 do not have a U-shaped groove formed at their tips, but every other protruding part 14b has stepped parts 14b with the front and back reversed, as shown in an enlarged view in FIG. 3B. It is formed.

These steps 14b! Every other protruding portion 13a of the lower half portion 9 is in a complementary relationship with the stepped portions 13d formed in the front and back, and is arranged so that the stepped portions do not butt against each other.

A slit portion 14C is provided between each protruding portion 14a, 14a.
It has become.

Therefore, when the lower half part 9 and the upper half part 10 are butted together and integrated, each of the opposing protrusions 13a and 14
a are butted against each other, the non-step portion of the upper protrusion 14a is butted against the step d of the lower protrusion 13a, and the U
A U-shaped small hole having a depth of approximately 1/2 is defined in the groove 13b, and a slit hole S is defined by the slit portion 13e and the slit portion 14c.

Yarn, etc. is guided through this part.

By the way, as is clear from FIG. 2A, the stepped portion 13b of the protruding portion 13a near the arm 9a side of the lower half portion 9 is in a state where it is all facing one side, and this of the upper half portion 10 is The part of the protruding part 14a facing the protruding part 13 also has a stepped part 14b.
It is formed only toward one side opposite to a.

This structure was adopted because the protrusions 13a and 14a come into contact first when the upper half 10 is rotated and integrated.
This is to enable smooth engagement between the two.

On the other hand, on the inside of the left and right support frames 7, 7 of the base 2, two vertical parallel guides 15, 15, as shown in an enlarged view in FIG. The spacing is approximately the same as the thickness of the wall.

A bottom plate 16 is provided protrudingly at the lower end between the guides 15, 15, and the guides 15, 1 are arranged so that the lower end of the protrusion 9e comes into contact with the bottom plate 16 when the yarn K is attached to the yarn K.
The protrusion 9e of the cover 8 is fitted between the gaps 5 and 5.

At this time, as shown in FIG. 4B, all the warp threads are at the same height.

Further, on the outside of one of the two guides 15, 15 provided on each of the left and right support frames 7, and near the upper end, a protrusion 17 extends horizontally over a predetermined length. It is formed.

Next, the operation and usage method of this embodiment configured as above will be explained.

First, a large number of yarns are wound around the thread winding pin 4 at predetermined intervals, and the protrusion 9e of the threader 8 is fitted between the guides 15, 15 of the support frames 7, 7.

In this state, the lower end of the protrusion 9e of the cover 8 is attached to the bottom plate 1.
It is in an upright state touching the top of 6.

In this state, the upper half 10 is opened around the shaft 11, leaving the U-shaped groove 13b of the protrusion 13a of the lower half 9 exposed.

In this state, the U of each protrusion 13a is applied to the yarn from the spool pin 4.
They are fixed to the cloth-wrapped rod 5 side by being fitted alternately into the letter-shaped grooves 13b and the slits 13e.

Next, the upper half 10 is rotated to form the protruding portion 14a and the protruding portion 13.
When the upper half 10 is fixed with the butt stopper 12, the yarn is guided into the U-shaped small hole 19 formed between the tips of the upper and lower protrusions 13a and 14a, as described above. At the same time, the blanket K can also move freely up and down in the vertically long slit holes S formed between the adjacent protrusions 13a and 14a, which are formed to face each other in a one-on-one manner. be guided as best you can.

After attaching the yarn K to the cloth 8 in this way, the cloth 8 is pulled out from between the guides 15 and 15, and the lower end of the protrusion 9e is placed on the horizontal guide 17 as shown in FIG. U-shaped R13b at the tip of the protrusion 13a of 9
, so the yarn in this part will rise, and the yarn in the slit hole S will remain in the same position as the beginning, so every other yarn will be placed in alternate positions vertically apart, and horizontally. When viewed from above, an elongated triangular space (shuttle) was formed.

A shuttle 20 is passed through this portion, and one weft thread is woven.

After passing one weft thread, if the lower end of the protrusion 9c of the weft 8 is placed directly on the support frame 7, then the groove 13
Since the yarn in b is lower than the yarn in long hole 19, the position of the yarn is reversed and a triangular space (shuttle) is formed between the upper and lower yarns when viewed from the side. .

If the shuttle 20 is inserted into this space from the opposite side, two weft threads will be woven.

Then, after passing the weft threads one by one, insert the weft thread 8 on the front side.
That is, it is pressed against the cloth winding rod 5 side, and the woven weft threads are brought together to close the weave.

Thereafter, the same operation is repeated to finish weaving the cloth, and when the length of the woven cloth becomes long, the cloth winding rod 5 is rotated via the dial 6 to wind up the cloth.

Since this embodiment is constructed as described above, the plaster which also serves as a reed is divided into two halves into upper and lower halves, and after passing the thread through the lower plaster, the upper plaster is fitted, and the upper and lower parts are separated. By simply integrating the thread, it is extremely easy to install the thread, and there is no need to pass the thread through slits or small holes formed in the conventional method. and the protruding part 14a of the upper half part 10 are joined in an intricate manner, so that the weft 8 is strong without being broken at the joining part even when the woven weft is gathered together.

By the way, in the above-mentioned embodiment, the operation of the cover 8 is in the position where it is fitted along the guides 15, 15, the position where it is placed on the protrusion 17, and the position where the protrusion 9c is placed directly on the support frame 7. Although this was done by changing the structure to , it is also possible to configure the structure so that the movement is performed only in the horizontal direction without performing such a movement, and an embodiment employing such a structure is shown in FIGS. 5 and 5. It is shown in FIG.

In this embodiment, a pair of left and right support frames 7, 7 of the base 2
A substantially disc-shaped bulge 21 is formed in a vertical plane opposite to a part of the bulge, and an arc-shaped guide groove 21a is formed in this part.

The circular arc-shaped guide groove 21a is formed in a dovetail shape, but the center portion thereof is formed in a circular arc shape in the linear guide groove 21b formed inside the support frames 7, 7. It is continuous through the inlet portions 21c, 21c.

Further, the guide groove 21b is sandwiched between two guide walls 21d that are vertically parallel to each other and protrude inwardly.

On the other hand, the cover 8 adopted in this embodiment is similarly divided into an upper half 10 and a lower half 9, as shown in FIG.
Both arms are rotatably connected at one end, which is exactly the same as in the first embodiment described above, but the left and right arms 9a, 9
The difference is that protrusions 22 are provided on both sides of the lower end of b.

Moreover, the size of these protrusions 22 and 22 is the same as that of the groove 21 described above.
a, 21b, and is large enough to be slidably fitted into
As is clear from FIG. A, protrusions 23 are formed on the side surfaces of the lower ends of the left and right arms 9a, 9b on the spool pin 4 side.

Near the lower end of the bulging portion 21 of the support frame 7, a pair of upper and lower protrusions 24 are provided at positions facing the lower end of the C-shaped groove 21a.
．． 24 is provided in a protruding manner, and a protrusion 23 is fitted between the two so that the brace 8 can be maintained in an upright state.

Further, in this embodiment, the protrusions 13a and 14a of the comb-teeth-shaped sections 13 and 14 formed in the upper and lower halves of the cover 8 are different from those in the previously described embodiments.

That is, the shell shown in FIG. 7 has one protrusion 13
An insertion projection 13g is formed at the tip of the insertion projection 13g, and a projection 14a formed complementary to the insertion projection 13g is formed at the tip of the insertion projection 13g.
A U-shaped insertion groove 14b into which d is inserted is formed.

In addition, the means for fixing one end of the upper half 10 is different, and the open end is rotatably supported by one arm 9a by an elastic support frame 25 having a U-shaped cross section. Upper half 1
0 is easy to attach and detach.

If such a structure is adopted, as shown in FIG. 5, when the protrusion 22 of the sheath 8 is located near the lower end of the C-shaped groove 21a, the entire sheath will be located at the lowest limit, and the yarn will be at the lowest position. It is lowered every other book and divided into upper and lower parts, and the shuttle 2
A space is created through which 0 can pass.

If the shuttle 20 is passed through this space, the weft is woven.

In this state, the protrusion 23 is fitted between the protrusions 24 and 24, and the vertical state can be maintained.

On the other hand, when the thread 8 is moved along the groove 21a to its upper end as shown in FIG.
is located at the highest limit, so every other shuttle is divided into upper and lower parts.
A space is created through which 0 can pass.

If the shuttle 20 is passed through this space, the weft is woven.

After weaving the weft threads, if the protrusion 22 of the weft 8 is pressed against the cloth winding rod along the guide groove 21b, it acts as a reed and the weave can be tightened.

At this time, since the protrusion 22 is guided by the upper and lower guide walls 21d, the cover 8 does not fall down.

Since the present embodiment is configured as described above, the position of the insert 8 can be displaced to the lowest limit, the highest limit, and the position where the weave is tightened only by the movement of the insert 8 back and forth.
The operation of the washing machine is extremely simplified, making hand-weaving easier.

As is clear from the above explanation, according to the present invention, since the plaster is divided into upper and lower parts, the work of attaching yarn, etc. to the plaster is extremely simplified, and the user can spend a lot of time on the hand-weaving work itself. The work efficiency is significantly improved, and the protrusion 13a of the lower half 9 of the cover 8
and the protruding part 14a of the upper half part 10 are joined in an intricate manner, so that the weft 8 does not break at the joined part and is strong even when the woven weft is pressed.
