Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a loom capable of disposing warp threads that move in the weaving width direction in addition to warp threads that extend linearly in the weaving direction. The present invention relates to a loom having a structure. That is, one heald bar having a large number of healds and guiding one warp thread group, at least one warp guide bar having a large number of guide needles with holes and guiding one warp thread group, and means for inserting weft threads. , and a reed, the heald bar and the warp guide bar perform a relative reciprocating motion so that the heddle passes across the group of warp threads guided by the warp guide bar, thereby being guided by the heald bar. In this loom, a closed gap and an open gap are formed between a warp group and a warp group guided by a warp guide bar, and wefts are inserted into these gaps.

[Prior Art] The above-mentioned loom is manufactured by, for example,
It is known from No. 0. If this known loom is used, it is possible to insert warp threads different from the ground warp threads in a meandering manner to form varied patterns such as tapestry fabrics and leno fabrics. For this purpose, this loom uses a needle (held) having a hole at its tip for guiding the threads, instead of using a normal heddle as a means for shedding the warp threads. The needle bar (warp guide bar) that guides the tapered warp or the entangled warp moves in the weaving direction above the adjacent ground warp, enters between the adjacent ground warps, descends, and moves between the ground warp and the entangled warp. and open it.

[Problems to be solved by the invention] In the above-mentioned loom, when the ground warp yarns are arranged in parallel in a high density, the tension of the yarns is weak, the yarns vibrate due to the vibration of the machine, and the yarns are Due to entanglement of fluff, the distance between adjacent warp yarns may become narrower than a predetermined distance, or in some cases, these warp yarns may become entangled with each other. It is very difficult to insert the heald correctly between such warp threads. That is,
Frequently, it is possible to mistakenly insert a particular heald into a space adjacent to this space instead of in the space between two proper warp threads adjacent to each other, which leads to weaving errors. Therefore, in order to prevent such errors, the density of the warp threads must be made considerably coarser.
It is not possible to obtain dense woven fabrics for clothing.

An object of the present invention is to provide a loom capable of weaving a fabric having a variable pattern and high density by arranging warp yarns that extend in a straight line in the weaving direction and warp yarns that move in the direction of width reduction. .

[Means and effects for solving the problem] The above-mentioned problem is solved by adopting the following configuration in the loom described in the "Industrial Field of Application" section.

That is, the heald bar is immovable in the weaving width direction and guides the warp group extending linearly in the weaving direction, and there are a plurality of warp guide bars to form a warp guide bar group, and these groups are Among them, at least one warp guide bar is movable back and forth in the weaving width direction, and guides the warp group that moves continuously or partially in the weaving width direction over the entire length in the weaving direction,
During the relative reciprocating movement of the heald bar and the warp guide bar, the heald bar is configured such that each of its healds enters between the guide needles of the warp guide bar.

Since the warp guide bars can guide as many warp groups as the number of traps, when combined with the warp groups guided by the heald bars, at least three warp groups are arranged on the fabric, forming a high-density fabric. becomes possible. Moreover, in that case, the heald of the heald bar passes between the guide needles of the warp guide bar, and the heald is not directly inserted between the warp threads between the tip of the warp guide needle and the weaving area. Therefore, even if the warp groups are guided with high density by each warp guide bar, the spacing between adjacent warp threads that make up each warp group may become narrow or they may become entangled in the heald insertion path. Therefore, the heald can be inserted accurately and errors in weaving can be prevented.

In one embodiment of the present invention, at least two of the warp guide bars constituting the warp guide bar group
One is movable back and forth in the weaving width direction, and guides the warp groups that move continuously or partially in the weaving width direction over the entire length in the weaving direction. With such a structure, it is possible to manufacture a fabric in which at least two groups of warp threads are shifted in the weaving width direction.

In another embodiment, the heddle bar guides the first warp group extending linearly in the weaving direction, and at least one of the warp guide bars constituting the warp guide bar group extends in the weaving width direction. The second warp group is immovable and extends linearly in the weaving direction, and at least one of the other warps is movable back and forth in the weaving width direction, continuously or partially over the entire length in the weaving direction. Alternatively, the warp groups moving in the weaving width direction may be guided respectively. In this case, it is possible to produce a fabric in which at least two warp groups extend linearly in the weaving direction and at least one warp group moves in the weaving width direction.

In this embodiment, at least two warp guide bars are disposed which are movable back and forth in the weaving width direction and each guide a group of warp yarns that move continuously or partially in the weaving width direction over the entire length in the weaving direction. can do. If this loom is used, it is possible to weave an extremely dense fabric consisting of two groups of warp yarns extending linearly in the weaving width direction, a group of weft yarns extending linearly in the weaving width direction, and two groups of warp yarns moving in the weaving width direction. It is possible.

In each of the above embodiments, the at least two warp guide bars that guide the warp group moving in the weaving width direction are
In the weaving width direction, they can reciprocate in the same direction, in opposite directions, or independently of each other.

In each of the embodiments described above, it is also possible to configure the warp guide bar group that guides the warp groups moving in the weaving width direction to arrange these warp groups obliquely in a straight line.

A common method for inserting weft threads is to use a shirttle, but this method moves the shirttle over the entire width of the fabric from one end of the weaving width to the other.
It takes time to insert the weft threads, making it difficult to operate the loom at high speed. Methods for inserting weft yarns at high speed include the water jet method and the air jet method.
The types of threads that can be used as wefts are restricted. That is, thick yarns such as large count synthetic fiber yarns, wool yarns, ring yarns, slub yarns, etc. may come into contact with the warp yarns, and are also extremely difficult to use because of air resistance.

The rapier method has fewer restrictions on the types of yarn that can be used than the water jet and air jet methods, but since the weft is still moved at high speed, there are still some restrictions on the types of yarn that can be used.

Of course, it is an embodiment of the present invention to insert the weft yarn from one end of the weaving width to the other end by means such as the shirt tor in both the closed gap and the open gap. In view of the above disadvantages, in another preferred embodiment of the present invention, a different 2810 means is provided as the means for inserting the weft yarn. That is, the first means is means such as the above-mentioned shirttle, and inserts the weft yarn into the closed gap from one end to the other end in the weaving width direction.

On the other hand, in the second means, the weft threads extending over the entire width of the fabric are inserted into the open gap simultaneously across the entire width while being translated in the weaving direction.

As this second weft insertion means, for example, a device known as a magazine weft insertion device in the field of warp knitting can be used. Details of this magazine weft insertion device are disclosed in, for example, Japanese Patent Publications No. 45-16896 and Japanese Patent Publication No. 47-16868.

This second weft thread insertion means does not move the weft threads from one end of the fabric to the other end, but simultaneously inserts the weft threads across the entire width of the fabric, which has conventionally been impossible to insert as weft threads. It is possible to insert different kinds of yarns, and weft yarn insertion can be performed at high speed. That is, when the above-mentioned second weft insertion device is used in combination, the time required for inserting the weft into the open gap using this device is short, so the time required for inserting the weft into the closed gap using a shuttlecock or the like is reduced. Therefore, the total time required for weft insertion can be shortened, and the speed can be increased.

Since the weft threads are inserted alternately by the first means and the second means, even types of weft threads that could not be inserted as weft threads are inserted every other weft thread, that is, partially in the weaving direction.
can be arranged.

Moreover, according to this magazine weft insertion device, it is also possible to insert several different types of wefts adjacently. For example, if the type of weft yarn inserted by the first means is A, and two types of yarns B and C are inserted by the second means, in the fabric, the weft yarns are A, B, A, They will be repeatedly arranged in the order of C. In this way, in the embodiment described above, it is possible to rapidly produce a densely woven fabric with a greater variety of patterns.

It is more preferable that the reed is used for beating the reed, and that the weft guiding means such as a shuttlecock or rapier in the first weft insertion means is configured to run on the reed as a guide.

A pattern chain or a pattern wheel commonly used in the field of warp knitting can be used as a means for driving the warp guide bar, which moves the warp yarn group in the weaving width direction, in its longitudinal direction, that is, in the weaving width direction. A pattern chain is made by connecting various chain links of different heights in an endless manner, and the raised and lowered surfaces of the series of chain links form a cam surface. This ceno is placed on one end of the warp guide bar in the longitudinal direction. The warp guide bar is biased by means such as a spring, so that the end of the warp guide bar is pressed against the cam surface either directly or via another member such as a rod. When the chino is rotated in this state, the warp guide bar is caused to reciprocate in the longitudinal direction by the high and low cam surfaces of the chino. In this case, the amount of displacement of the warp guide bar is determined by the height difference of the cam. A pattern wheel is a cam with diametrical irregularities on the periphery of a disc, and its function is the same as that of a pattern chain. Instead of such mechanical means such as a pattern chain or a pattern wheel, the movement of the warp guide bar can also be controlled by electromagnetic means.

[Example] In FIGS. 1 to 6, lO is a warp guide bar group, which is composed of three warp guide bars 12, 14, and 16. Each warp guide bar extends in the direction perpendicular to the plane of the paper, that is, in the weave width direction of the fabric A, and at its lower end, a large number of guide needles 20 each having a guide hole at the tip are inserted through a block 8. It is provided. Three warp groups a, b, and c sent out from a warp beam (not shown) are attached to these warp guide bars 12.14.
．． Guided by 18. That is, the warp group A passes through the guide needle 20 of the warp guide bar 12 on the left in the figure, the warp group C passes through the guide needle 20 of the center warp guide bar 14, and the warp group C passes through the guide needle 20 of the warp guide bar 16 on the right. and is guided to the weaving area 21 below. In this specification, the upper end of the finished part of the woven fabric, that is, the boundary between the woven fabric and the mere thread part, will be referred to as the woven region 21.

As will be explained in detail later with reference to FIGS. 9 and 10, the warp group a constitutes a second warp group arranged in the weaving direction of the finished fabric. Therefore, the warp guide bar 12 that guides the warp does not move in the weaving width direction of the fabric, that is, in the direction perpendicular to the paper (unlike this embodiment, the warp guide bar 12 moves in the weaving width direction). When guiding the thread, this guide bar 12 moves in a direction perpendicular to the paper surface)
. The warp groups are arranged in a diagonal direction in the fabric A, and the warp groups C are arranged in a diagonal direction as well, but in a different direction than the warp groups. Therefore, the warp guide bars 14 and 16 that guide these warp groups c reciprocate in opposite directions in the width direction of the fabric A.

That is, when the warp guide bar 14 is moving from the front side to the back side in the paper, the other bars 16 are moving from the back side to the front side in the paper.

The warp guide bar 12, 14, 16 is supported by a lever 26 via a hanger 22, a fixed shaft 24. The lever 26 is connected to the connecting rod 28
By interlocking with a cam means (not shown) through the
The guide bar 12.14.1G swings from side to side in the figure, centering on the shaft 24.

Accordingly, the lower end of the guide needle 20 makes a substantially horizontal linear reciprocating motion (more precisely, an arcuate motion with a large radius of curvature about the shaft 24).

As mentioned above, the warp guide bars (14, 16) that guide the warp groups (b, c) move in the weaving width direction, and the means for this movement is a pattern chain or a pattern wheel commonly used in the field of warp knitting. can be used.

The case of using a pattern chain is illustrated in FIG. The pattern chain links 90 are formed by endlessly connecting various chain links 92 having different heights, and the uneven surfaces of the series of pattern chain links form a cam surface 93. This chain link is arranged on the chain drum 91 at one end in the longitudinal direction of the warp guide bar. The warp guide bars 12, 14, 16 are connected to the lower body 8 under the upper body 8B.
8 is suspended, and an upper body 86 is slidably held by a hanger 22. Warp guide bar 12.14
, 113 is biased via means such as a spring 94, thereby causing the warp guide bars 12.14, 1
(The end of i is pressed against the cam surface 93 of the pattern chain 92 via the transmission member 96 and rod 98.

When the chino 90 is rotated in this state, the warp guide bar 14. l[i is caused to reciprocate in the longitudinal direction by the cam surface 93 of the chino 90, which has a height and a height. In this case, the amount of displacement of the warp guide bar is determined by the height difference of the cam.

Although not shown in the drawings, the pattern wheel is a cam with diametrical irregularities provided on the periphery of a disc, and its function is the same as that of a pattern chain. Further, instead of mechanical means such as a pattern chain or a pattern wheel, the movement of the warp guide bar can be controlled by electromagnetic means.

30 is a heald bar, and guide bar 12.14,1
13, it extends in the weaving width direction of the fabric, and a large number of needle-shaped healds 34 each having a guide hole at the tip are provided in a substantially horizontal direction through a block 32 at its tip. . Similarly, one warp group d sent out from a warp beam (not shown) passes through a hole in the heald 34 and is guided to the weaving area td21. The warp group d guided by this heald bar 30 constitutes a second warp group arranged in the weaving direction of the fabric A.

The heald bar 30 is supported by a C-shaped lever 38, which is rotatably supported by a shaft 40 whose position is fixed. The center of the curved portion of the lever 38 is connected to a cam lever 44 via a connecting rod 42, and is interlocked with a cam 46 that rotates around a shaft 45. A pair of cam rollers 47 move in contact with the inner and outer peripheral surfaces of the cam 46 and function as cam followers. Rotation of the cam 46 causes the rod 42 to move up and down via the cam roller 47, which causes the lever 38 to move up and down.
performs a rocking motion about the shaft 40.

At this time, as shown in FIGS. 4 to 6, which will be described later, the heald 34 passes between the guide needles 20 of the warp guide bar group 10 and horizontally forms a nearly straight line (more precisely, ,
(A circular arc with a large radius of curvature centered on the shaft 40)
Make a reciprocating movement.

48 is a reed, and is made up of a block 50 and a reed feather 52 attached thereto. The reed 48 is supported by a crank lever 54 via a reed beating bar 53. crank lever 54
The base end of the crank lever 54 is connected to a cam lever 58 via a connecting rod 56, and the middle portion of the crank lever 54 is connected to the same cam lever 58 via a ■-shaped arm 60 and a connecting rod 62 (see above). In the tδ construction, all connection points of each member are rotatable). The cam lever 58 is interlocked with a cam 66 that rotates around a shaft 64. 67 is the cam roller 4
This is a cam roller similar to No.7. Due to the rotation of the cam 66,
On the one hand, the vertical movement of the rod 56 causes the crank lever 54 to swing around the fulcrum pin 68, and on the other hand, the vertical movement of the rod 62 causes the ■-shaped arm 60 to swing around the fixed shaft 70. However, this rocking motion is transmitted to the crank lever 54 via the fulcrum pin 68. As a result, the reed 48 disposed at the tip of the crank lever 54 performs an arcuate reciprocating motion between the upper left and lower right of the figure as a combination of these two types of rocking motion, and such reciprocating motion As a result, the reed 48 enters and retreats into the weaving area 21.

Reference numeral 72 indicates a weft insertion device such as a shuttlecock or rapier for inserting a weft into the fabric from one end of the width to the other end. e is the weft thread inserted by such a device.

74 is a magazine weft insertion device. For simplicity,
This device is shown only in FIGS. 1 and 2. This device 74 operates in a plane parallel to the paper surface on both sides of the fabric A in the weaving width direction, that is, on the front side and the back side of the paper surface.
Each runs an endless Cheno 76, and this Cheno 7
6 is provided with locking parts (not shown) for the weft f at predetermined intervals, and both chains 7
8. Fabric A is placed between each pair of opposing locking portions of 78.
The weft f, which is approximately the same length as the width of the fabric A, is wrapped around the weft f, and the weft f held in the weave width direction of the fabric A in this way is translated in the direction of the weaving area 21 as the chano 78 moves in the direction of the arrow. It is something that makes you

78 is a sprocket that guides the chino 76.

More specifically, this device 74 is
It can be carried out according to No. 96 or Japanese Patent Publication No. 47-18868.

Reference numeral 80 denotes an immovable guide bar for the fabric A, which is composed of a pair of elongated members facing each other with a gap that allows the fabric A to pass through. It extends over the entire width in the direction. 82 is a support for the fabric A guide bar 80. 84 is a guide roll that guides the woven fabric A.

Next, the operating process of the above device will be explained using FIGS. 2 to 6. In addition, in each figure, the warp guide bar group l
Arrows placed near O, the heald bar 30, and the reed 48 indicate the directions in which these members move between the illustrated step and the next step.

In FIG. 2, the warp guide bar group IO is connected to the shaft 2
4, and the guide needle 20 disposed at its tip is at its leftmost position, that is, at its most retreated position from the weaving area 21. Similarly, the heald bar 30 is located at the rightmost position, that is, at the most retreated position from the weaving area 21. In this way, the warp guide bar group lO guides the 3
The warp groups a, b, and c and the warp group d guided by the heald bar 30 are open and form an open gap y. More specifically, the warp group a is located between the guide needle 20 and the weaving region 21.

The inverted triangular gap y formed by portions b and c and the portion of warp group d located between the heald 34 and the weaving area 21 has no warp group located at the base of its upper end. is open because it does not exist. In the illustrated state, the magazine weft insertion device 74 passes through this upper opening and brings the weft r'' into the open gap y.

In FIG. 3, the warp guide bar group IO has moved slightly to the right, and the heald bar 30 has moved slightly to the left, approaching the position directly above the weaving area 21, so that the warp threads guided by both The gap y formed by the groups is narrowed. At this time, the weft r° located in the gap y is pinched by both warp groups, and is also held by the reed 48 which has moved downward to the right from the state shown in FIG. It is being held down and moving downward.

In FIG. 4, the warp guide bar group 10 continues to move to the right, and conversely, the heald bar 30 continues to move to the left, so that it is directly above the weaving area 21. In this position, the heald 34 passes between the guide needles 20 (see FIG. 7), and the tip of the heald 34 projects to the left of the rightmost warp guide bar 12. As a result, the gap y formed by the warp groups that existed in FIGS. 2 and 3 is closed, and the weft f° is completely captured by the warp groups. Then, the reed 48 descends to just above the weaving area 21 and moves the weft 1° into the weaving area 21.
is being pushed into.

In FIG. 5, the warp guide bar group 10 has moved to its rightmost position, and the heald bar 30 has moved to its leftmost position. As a result, the tip of the heald 34 protrudes longest outward to the left of the warp guide group 10, thereby causing the three warp groups a and b to be guided by the warp guide bar group IO.

A closed gap X is formed between C and the warp group d guided by the heald bar 30. In other words, the gap X of this inverted triangle is located at the location where the base of the upper end is located.
The portion of the warp group d before passing through the heald 34 is located and closes this gap. The figure shows a state in which the weft e is inserted into the closed gap X from one end to the other end in the weaving width direction of the fabric by a weft inserting device 72 such as a shuttlecock or rapier. When the device 72 inserts the weft yarn, a shuttlecock, a rapier, etc. pass over the reed 48 using the reed as a guide. Thereafter, the reed 48 moves backward to the upper left while avoiding the weft e.

In FIG. 6, the warp guide bar group lO has started to move back to the left, and the heald bar 30 has started to move back to the right, the gap a, b, c and d, and is located directly above the woven area 21.

While each process shown in FIGS. 2 to 6 is being carried out, the warp guide bars 14 and 18 that guide the diagonal warp groups c that intersect with each other are moved in the weaving width direction of the fabric, that is, in the plane of the paper. It continues to reciprocate in the vertical direction. In this embodiment, both guide bars 14,18 carry out movements in opposite directions. The movement is performed via a pattern chain or the like, as described above. In that case, the timing of the longitudinal movement of both guide bars 14.18 (main,
In order to allow the heald 34 to enter the guide bars 12, 14, 16, the gaps formed by the two adjacent guide needles of these warp guide bars coincide with each other. It has to be something.

Of course, the warp guide bar 12, the heald bar 30, and the reed 48 are immovable in the weaving width direction of the fabric.

One cycle of the weaving operation is completed through the steps shown in Figures 2 to 6 above, and by repeating this cycle, the fabric A
is continuously formed, and this fabric A is wound up on a winding roll (not shown) via a guide roll 84.

In this embodiment, the warp guide bar group and the heald reciprocate in opposite directions so that they approach and separate from each other, but instead of this, one may be fixed and only the other reciprocated. Accordingly, the heald may be moved in and out relative to the warp guide bar. In any case, it is essential to the invention that the heald passes through the guide needle.

In addition, in this embodiment, the reed 48 beats the weft f only once during one cycle of operation, but the reed 48 beats the weft once each for the two wefts e and f. It's okay.

FIG. 9 and FIG. 10 show an example of a fabric A manufactured by the loom of the present invention. The warp in the weaving direction is the first warp a
and the second warp d are arranged alternately, and the weft is a shuttle,
Weft yarns e inserted by means such as a rapier and weft yarns f inserted by a magazine insertion device are alternately arranged. The diagonal thread consists of a thread C on the upper left side and a thread C on the upper right side that intersects this thread. For example, if 28 warps are inserted between the guide needles 20 of the warp guide bar 12 and the heald 34 per inch, the number of warp threads in the weaving direction of fabric A is 56 per inch. If there are 28 threads in both diagonal directions, and 28 threads are arranged in 1-inch intervals, the fabric will appear to have a density of 112 threads, which is four times as many as 28 threads in 1-inch. A will be obtained.

The vertical relationship of the doubling yarns in fabric A is as follows. Fabric A in FIG. 10 shows the state seen in the direction of the arrow in FIG. 1, so the warp threads a and b.

Regarding C, a warp thread a guided by the guide bar 14 on the right side is arranged above the warp thread a guided by the warp thread guide bar 12 on the left side of FIG. Warp yarns C guided by bars 16 are arranged. The second warp thread d is guided by the heald 34, and the second warp thread a is guided by the heald 34.
, b, and c, it meanderes alternately above the warp threads a, b, and c and the weft thread f, and below the weft thread e.

The weft e is above the warp d but below all other threads. Also, the weft thread f is below the warp thread d, but above all other threads.

Regarding the yarns a, b, and c, if the horizontal order of the guide bars 12, 14, and 18 that guide these yarns is changed, the vertical relationship in the fabric A is also changed.

Note that FIG. 9 is an enlarged view of a minute portion of the fabric knitted by the above method. Therefore, although the diagonal warp threads s and c extend in the same direction, in reality, they are arranged in a zigzag shape, bending from side to side with a width of about 1 cm, for example (see Fig. 11 (1)). .

In this way, the diagonal straight threads are bent evenly from side to side and continuously reciprocated over the entire length in the weaving direction, but instead of this, for example, (2) to ( 5
), any regular or irregular arrangement is possible. As shown in this figure, the warp threads moving in the weaving width direction may continuously move in the weaving width direction over the entire length in the weaving direction ((+) (2)
), or it may shift in the weave width direction in a part of the weave direction, and extend linearly in the weave direction in the remaining part (
(See (3) to (5) in the same figure).

Further, the reciprocating movement in the weaving width direction does not have to be uniform from side to side (see (4) in the same figure), or may be completely random (see (5) in the same figure). Furthermore, when there are multiple warp threads that move in the weaving width direction, they may move in opposite directions as in the above example, or may move in the same direction, or they may not move in any regular manner with each other. You can migrate regardless.

In addition, in the claims section, reference numbers attached to each member in the examples are cited, but this is merely an example, and the structure of the claims is different from that in the examples. It is not limited to the specific structure and shape of each member or the structural relationship between each member.

[Effects] According to the loom of the present invention, it is possible to arrange warp threads in the diagonal direction of the fabric in addition to the warp threads extending in the weaving direction of the fabric to form various patterns, and moreover, it is possible to construct a variety of patterns. Can weave cloth.
