Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a selvage forming device, and more particularly to an improvement in a device for forming a woven fabric selvage using a selvage structure.

The knitted texture is formed by the kneaded warp, the ground warp, and the weft, but in this inward folded weave, the kneaded warp is always above the weft.

The present invention is directed to a technique for forming an ear rim using the strained tissue in the strained tissue. When forming the raking tissue, it is necessary to change the position of the raking threads on the left and right sides of the ground warp every appropriate number of picks so that the threads are entwined with the ground warping.

Various types of equipment have been used for this task, but all of them suffer from at least one of the following drawbacks:
However, the current situation is that it cannot be said to be sufficient from the standpoint of action and effect. (a) In order to form a sufficiently strong ear rim, it was unavoidable that the structure would become larger and more complicated.

(b) Since it is complicated and has many movable parts during movement, it is prone to failure and lacks durability as a device. (c) Since the contact points between the yarn and the yarn guide member are limited, the yarn path tends to get stuck, and it is necessary to frequently replace parts to avoid yarn fluffing and yarn breakage.

(d) Since the motion of related members is complicated, it is difficult to follow the high-speed operation of the loom, and it is also difficult to increase the number of strokes.

(e) Due to its complex structure, there are many parts that cannot be checked from the outside, which not only delays the discovery of failures but also makes maintenance work difficult.

(f) When moving the thread for kneading, the thread is subjected to excessive bending, which tends to damage the warp thread.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and its features are, first of all, the so-called MA
The second point is that the opening movement of the heald is used to cause the related members to perform only a simple up-and-down movement and a simple rocking movement, and the third point is that the above-mentioned members are The point is that the contact area between the thread and the member is made variable by distributing the thread alternately to the left and right sides of the earth's warp plane by the oscillating motion. The point is that the distribution to the left and right as described above can be performed simply by bending.

The ear rim forming device of the present invention will be explained in more detail below with reference to the accompanying drawings.

In the following explanation, for ease of understanding,
The device will be described as being installed on a loom, and from this perspective, expressions such as 1, top, bottom, front, back, left, right, etc. will be used, but it is of course not limited to these expressions due to its structure.

still,. The front and back are looms. When attached to the machine, the cloth side is in the front and the transverse beam side is in the back.
Furthermore, 1 left and right refers to the positional relationship between the left and right as seen from the front of the loom. Illustrated in FIGS. 1-3 are embodiments of the apparatus of the present invention.

The left rod 2 and the right rod 4, which are spaced apart from each other in the right and left directions and extend parallel to the vertical direction, have upper pieces 2a, 4a and lower pieces 2b, 4b, each having a larger cross-sectional area, at their upper and lower ends. Both rods 2 are integrally connected through these pieces.
, 4 are connected to respective plain weave healds (not shown) so as to move up and down together. As is clear from FIG. 1B, a guide needle holder 6a (hereinafter abbreviated as 1 upper holder) is located below the upper pieces 2a and 4a and is loosely fitted to both rods 2 and 4. A distribution guide holder 6b (hereinafter abbreviated as 1-lower holder) is positioned above the pieces 2b and 4b and is loosely fitted to both rods 2 and 4.

Both ends of a spring 8 disposed at the rear are properly connected to these 6a and 6b, and the elastic force of this spring causes the upper holder 6a to connect to the upper pieces 2a and 4a, and also to the lower holder 6.
b is in a state of being elastically pressed by the lower pieces 2b and 4b, respectively. A bifurcated guide needle 10 extending downward is fixed at the upper end of the upper holder 6a at approximately the center of its front surface.

This guide needle 10 consists of a pair of upper and lower thread guiding holes 10a, 1.
There are two sets of 0b distributed to the left and right. A stopper 9 is integrally fixed approximately at the center of the left rod 2.

Place the upper left extension on this stopper 9,
A sorting guide drive arm holder 12 (hereinafter abbreviated as holder in 1) is provided with its upper left extension portion loosely fitted to the left rod 2 and its lower right extension portion loosely fitted to the right rod. In the center of the front surface near the lower end of the middle holder 12, distribution guide driving arms 14a and 14b extending left and right are coaxially and loosely fitted with a shaft support P at their inner ends, respectively. At the center of the front surface of the lower holder 6b, the lower ends of left and right distribution guides 16 and 17 extending upward are loosely fitted and supported R, and the upper ends of these distribution guides 16 and 17 are attached to the lower end of the guide needle 10. located in close proximity. When the shed shown in FIG. 1A is closed, that is, when the left and right rods 2 and 4 are in their neutral positions, the upper surface of the right rod loosely fitting portion of the lower holder 6b and the lower surface of the right rod loosely fitting portion of the middle holder 12. A predetermined gap D is left between them. Further, as shown in FIG. 2, a tension spring 18 is interposed between the middle holder 12 and the back surface of the lower holder 6b. The spring force of this tension spring 18 is made smaller than the spring force of the spring 8 described above. FIG. 3 shows in more detail the structure of each yarn guide member (guide needle 10, distribution guides 16, 17) and the positional relationship in the state in which the shed is closed.

The order of the three components is the guide needle 10, the distribution guide 17, and the distribution guide 16 when viewed from the front.

However, the relationship between the front and back of these thread guiding members does not have any particular significance in this invention, and in practical use, the effects of this invention will not be diminished even if they are designed appropriately as necessary. In this state, the left and right sorting guide drive arms 14a, 14b assume an outward downward oblique posture, and the left and right sorting guides 16, 17 at their outer ends, respectively.
It is pin-coupled Q to the body near the lower end. As described above, the guide needle 10 has a pair of left and right thread guide holes 10b at its lower end.

As will be described later, since the guide needle 10 is for guiding the ground meridian GY, a vertical plane that includes the center of the yarn guiding hole 10b and runs back and forth will be hereinafter referred to as a ground meridian plane GYP. A pair of left and right yarn guide holes 16a and 16b are formed through the left distribution guide 16, and when viewed from the front of the device, the left yarn guide hole 16a appears to be on the inside of the left ground plane GYP. The right yarn guide hole 16b is formed to be located outside the right earth plane GYP.

The right distribution guide 17 also has a pair of left and right yarn guide holes 17a, 17.
When viewed from the front of the device, the left thread guide hole 17a is formed to be outside the left ground plane GYP, and the right thread guide hole 17b is formed to be located outside the right ground plane GYP. It is formed so that it comes inside.

The operation of each part explained above will be explained next with reference to FIGS. 4A to 4F.

The thread threading method is as follows: The ground warp GY is the upper thread guide hole 1 of the guide needle 10.
0a to the lower thread guiding hole 10b, and runs forward from the thread guiding hole 16a of the left distribution guide 16 to the thread guiding hole 16a of the left distribution guide 16. The threads TY2 run forward through the thread guiding holes 17a of the right sorting kite 17, respectively. In addition, since the cylinder is omitted in the figure, the parts around the distribution guides 16 and 17 are omitted, and the pivot point P1 of the distribution guide drive arms 14a and 14b is the distribution guide and the guide 16.
, 17 are replaced with the pivot point R.

Since both rods 2 and 4 are connected to the plain weave heald via the upper and lower pieces 2a, 2b, 4a, 4b, the left rod 2
When the right rod 4 rises, the right rod 4 descends by the amount of the rise, and when the left rod 2 descends, the right rod 4 rises by the amount of the fall.

Now, when the right rod 4 starts to rise from the neutral position shown in FIG. 4A, the left rod 2 descends accordingly.

As a result, the stopper 9 fixed to the left rod 4 also falls, so that the stopper 9 is loosely fitted to both rods 2 and 4 and the tension spring 1
The middle holder 12, which is being pulled downward by the rod 8, also descends together with the left rod 2.On the other hand, the right rod rises, so the lower holder 6b is pushed up by the lower piece 4b and rises. That is, the pivot point P on the middle holder 12 moves down, and the pivot point R on the bottom holder 6b moves up.As will be described later, in this invention, this relative motion is It is used to allocate left and right of TYl and TY2 with respect to the geological longitude GY.For convenience of explanation below, this is referred to as the 1st relative movement.The middle and lower holders in the neutral state shown in Figure 4A Since the gap between 12 and 6b is D, the above first relative movement causes the middle holder 12 (i.e., the pivot point P) to descend by Dl2, and the lower holder 6b (i.e., the pivot point R) to rise by Dl2, Both are in contact and the gap is O
It continues until .

That is, the first amount of relative movement is equal to D. FIG. 4B shows a state in which both holders 12 and 6b are in contact with each other. The first relative movement is completed when both holders 12 and 6b come into contact,
Thereafter, the middle holder 12 is pushed up by the lower holder 6b and both rise together, so that the pivot points P and R rise while maintaining the vertical positional relationship shown in FIG. 4B.

On the other hand, as the left rod 2 descends, the upper holder 6a is pushed down via the upper piece 2a, so the guide needle 10 integrated therewith also descends by the same distance. If the above-mentioned vertical movement continues further, the state shown in FIG. 4C will eventually be reached.

In this state, the ground warp GY guided by the guide needle 10 becomes the lower sheet of the shed, and the ground warp Hl, TY2 guided by the left and right sorting guides 16, 17 become the upper sheet, so weft insertion is possible. When this is done, the weft W goes up the ground warp QY and the weft warp TYl
, below TY2. The movements of each part described above are summarized in Table 1.

When the weft insertion is completed, in the next cycle, the right rod 4 starts to descend from the position shown in Fig. 4C, and the left rod 2
begins to rise.

Since the lower holder 6b is biased by the spring 8 as the right rod 4 descends, it descends following the lower piece 4b, and the pivot point R integrated therewith also descends. Since the middle holder 12 is pulled toward the lower holder 6b by the tension spring 18, the middle holder 12 also descends together with the lower holder 6b, and the pivot point P also descends. That is, at this timing, both shaft fulcrums P and R descend while maintaining the vertical positional relationship in FIG. 4C and, furthermore, in the vertical positional relationship in FIG. 4B. On the other hand, as the left rod 2 rises, the upper holder 6a is biased by the spring 8, so the upper piece 2a
The guide needle 10, which is integrated with this, also rises. Of course, as the left rod 2 rises, the stopper 9 also rises together. As the right hand 4 continues to descend and the left rod 2 continues to rise, the stopper 9 integrated with the left rod 2 eventually rises and comes into contact with the bottom of the middle holder 12 again. This state is shown in FIG. 4D. As this state progresses further, the lower holder 6b continues to descend, and the pivot point R integral with it also descends.

On the other hand, since the stopper 9 integrated with the left rod 2, which is continuing to rise, pushes up the middle holder 12, the pivot point P now starts to rise. In other words, relative motion occurs again between the pivot points P and R,
As a result, the left and right divisions of the ground meridians TYl and TY2 with respect to the ground meridian GY are performed. Hereinafter, this will be referred to as the first and second relative motion. With the second relative movement, the shaft support point P rises and the shaft support point R
Since the is lowered, the tension spring 18 interposed between the two is expanded. Of course, during this time the guide needle 10 continues to rise. In this case, as mentioned above, the amount of the first relative movement is D, and this completes the left-right distribution of the curvature meridians TYl and TY2 with respect to the earth meridian GY, so the second relative movement is It suffices if the amount of is also D.

That is, this second relative movement may be completed when the pivot point P rises by Dl2 and the pivot point R descends by Dl2 from the position shown in FIG. 4D. The state at the time when this second relative movement is completed is shown in FIG. 4E.

Since this state is exactly the same as the neutral state shown in FIG. 4A, the shed is in a closed state at this timing. Further, when the right rod 4 continues to descend and the left rod 2 continues to rise, the middle holder 12 is pushed up by the stopper 9, so the pivot point P goes up, and the lower holder 6b is pushed up by the lower piece 2b, so the pivot point P goes up. R also increases by the same distance.

That is, at this timing, the shaft fulcrums 4P and 4R are the fourth
While maintaining the vertical positional relationship shown in FIG. E, that is, the vertical positional relationship shown in FIG. 4A, they rise together. On the other hand, the guide needle 10 turns downward after the neutral state, and the upper piece 4a
continues to descend with the descent of If the above-mentioned vertical movement continues further, the state shown in FIG. 4F will be reached.

In this state, the ground warp GY guided by the guide needle 10 becomes the lower sheet of the shed, and the ground warp Hl, TY2 guided by the left and right sorting guides 16, 17 become the upper sheet, so weft insertion is possible. When it is done, the weft W is kneaded on the ground warp GY,
It will be below TY2. The movements of each part described above are summarized in Table 2.

Next, referring to FIG. 5A and FIG. 6A, a description will be given of the operation of forming the ear edge of the retracted tissue using the apparatus having the structure and operation as described above.

In addition, in the figure, for convenience of display, the ground longitudinal plane GYP is substituted for the ground longitudinal plane GY, and the thread guide holes 16a and 17a for the left and right distribution guides 16 and 17 are substituted for this. Further, in this example, two rows of left and right squirming structures are formed at the same time, but for convenience of explanation, only the left row in the figure will be described.
As mentioned above, the distribution of the draw warp TYl (thread guide hole 16a) and draw warp warp TY2 (thread guide hole 17a) to the left and right with respect to the ground warp GY is performed at the first and second points of the shaft fulcrums P and R. This is done using relative motion.

The contents of these relative movements are shown in Table 3. 1st
The relative movement of starts from the states shown in FIGS. 4A, 5A1, and 6A, and is completed in the states shown in FIGS. 4B, 5C, and 6C.

In the states of Figures 5A and 6A, the first sutra TYl
is guided by the thread guide hole 16a to the right side of the ground warp plane GYP, and the other thread warp TY2 is guided to the thread guide hole 17a to the left side of the ground warp plane GYP, and from above the ground warp GY, Scripture TYl, T
They are located in the order of Y2.

When the first relative movement begins, the middle holder 12 and the lower holder 6b approach each other, and the pivot points P and R also approach accordingly.

As a result, the left and right drive arms 14a, 14 shown in FIG.
b swings upward about the pivot point P, and the pin connection point Q moves upward and outward, and along with this, the left and right distribution guides 16
, 17 swing outward about the pivot point R, respectively.
That is, the thread guide hole 16a moves to the left, and the thread guide hole 17a moves to the right. Therefore, as shown in Figure 5B, the sutra TYl
is pushed by the right edge of the thread guide hole 16a and connects to the ground plane GYP from the inside.
The winding warp TY2 is pushed by the left edge of the thread guiding hole 17a and approaches the ground warping plane GYP from the outside. This state is shown in FIG. 6B. As the relative motion further progresses, the curvature meridian TY1 rises up the earth meridian plane GYP and moves outward, and the gyri meridian TY2 moves inward beyond the earth meridian plane GYP.

At this timing, since the vertical relationship of each warp remains unchanged, the crossing of the thread warps TYl and TY2 due to the above movement is performed with the ground warp GY on the lower side and the thread warp TYl on the upper side. Figure 5C
, the first relative movement ends in the state shown in FIG. 6C, and the first twisting motion is completed. From now on, until the shedding is complete, the vertical relationship of each warp is from the top to the warp warp TYl, TY.
2. The order of the geological longitude is ``GY'', and weft insertion is performed, so the 6th
As shown in Figure D, the weft W is above the ground warp GY, and the weft warp TYl is above the ground warp GY.
It is inserted through below TY2. The second relative motion is the fourth
The process starts from the states shown in FIG. D, FIG. 5C, and FIG. 6D, and ends in the states shown in FIGS. Figure 5C
, in the state shown in FIG. 6D, one thread warp TYl is guided to the thread guiding hole 16a to the left of the ground warp plane GYP, and the other thread warp TY2 is guided to the thread guiding hole 17a to the ground warp plane GYP. To the right of the plane GYP, and from above, the earth meridian ρY1, the earth meridian TYl, TY.
They are located in the order of 2.

When the second relative movement begins, the middle holder 12 and the lower holder 6b are separated, and the pivot points P and R are also separated accordingly.

As a result, the left and right drive arms 14A, 14b swing downward about the pivot point P, the pin connection point Q moves downward and inward, and accordingly, the left and right distribution guides 16, 17 are moved to the pivot point R.
3, and attempts to oscillate inward to the state shown in FIG. 3. That is, the thread guide hole 16a is connected to the thread guide hole 17 on the right side.
a moves toward the left. Therefore, as shown in FIG.
Pushed by the right edge of a, it approaches the geolongitudinal plane GYP from the inside.
This state is shown in FIG. 6E. As the relative motion further progresses, the curvature meridian TY1 moves inward beyond the earth meridian plane GYP, and the curvature meridian TY2 moves outward beyond the earth meridian plane GYP.

At this timing, since the vertical relationship of each warp remains unchanged, the crossing of the drawn warps TYl and TY2 due to the above movement is performed below the ground warp GY and with the drawn warp TYl above. Figure 5 E1
The second relative movement ends in the state shown in FIG. 6F, and the second twisting operation is completed.

After this, until the shedding is complete, the vertical relationship of each warp is from the top to the ground warp TYl, TY2, ground warp GY, and since weft insertion is performed, the weft W is ground warp GY as shown in Figure 6C. upon,
It is inserted through the lower part of the sutras TYl and TY2. By repeating the above steps, the Earth Kei TYl and TY2 can be
It moves alternately to the left and right of Y, and weft insertion is performed each time.
An ear rim of twisted tissue as shown in FIG. 7 is formed.

In this twisting structure, the twisting meridians TYl and TY2 always intersect below the ground meridian GY, with the twisting meridian TYl on top, and the twisting meridian TY. l, TY2 are always above the weft w, and the ground warp GY is always below the weft W. Now, in the first embodiment described above, a pair of left and right rods 2,
4, and by interlocking them with the plain weave heald and raising and lowering them alternately on the left and right, the middle holder 12
The structure is such that a relative movement is made between the lower holder 6b and the left and right distribution guides 16 and 17, thereby causing the left and right sorting guides 16 and 17 to swing.

However, with such a configuration, when one rod (for example, 4-piece hand 4) moves up and down, the other rod (for example, rod 2)
) In order to avoid collision with the heald on the side, each holder 6a, 6b, 12, etc. is given a complicated shape and both rods 2,
It was necessary to shift the position of 4 back and forth.

Furthermore, since the two rods 2 and 4 passing through a certain holder move in opposite directions, the holder may become distorted when the speed is increased. FIGS. 8A and 8B show another embodiment of this invention that takes this point into account, and is constructed so that the movement of the rod passing through the holder does not cause twisting.

Since most of the configurations are common to the first embodiment, common parts will only be given common references and symbols and their explanation will be omitted, and parts that differ in structure and operation will be explained with new reference symbols. do. Further, the area around the distribution guide is omitted in the figure, and the pivot points P and R are used instead. The upper and lower rear pieces 22a and 22b are fixed to both ends of a pair of left and right rods 22, and are connected to one of the plain weave healds so as to be interlocked.

The upper and lower front pieces 24a, 24b are operatively connected to the other plain weave heald, but these pieces do not involve rods. That is, the upper and lower holders 6a, 6b are urged into pressure contact with each other by the elastic force of the spring 8. However, for the purpose of suppressing the movement of the upper and lower front pieces 24a and 24b, pins may be protruded from these and loosely fitted into holes drilled in the pressure contact surfaces of the corresponding holders 6a and 6b, respectively. Next, the operation of each part will be explained with reference to FIGS. 9A to 9D. The yarn guiding method and the like are completely the same as in the first embodiment. Since the front and rear pieces 24a, 24b, 22a, and 22b are connected to the plain weave heald, when one rises, the other falls by the same amount.

For the sake of brevity, only the upper pieces 24a and 22a will be mainly mentioned below, but the corresponding lower pieces 24b and 22a will be described below.
Of course, b also moves in the same way. Immae Peace 24
When a starts to rise from the neutral position shown in FIG. 9A, the rear piece 22a descends accordingly. As a result, the stopper 9 fixed to the rod 22 also falls, so that the pivot point P on the middle holder 12, which is loosely fitted to the rod 22 and is pulled downward by the tension spring 18, also falls. On the other hand, as the lower front piece 24b rises, the lower holder 6b is pushed up,
The pivot point R above it rises. That is, the pivot points P and R perform a first relative movement in which they approach each other. Middle holder 12 is D
When the lower holder 6b descends by I2 and rises by Dl2, the two come into contact and become in the state shown in FIG. 9B, completing the first relative movement. When the front piece 24a further rises, the middle holder 12 is pushed up by the lower holder 6b which is in contact with it, and both rise together, so that the pivot points P and R are as shown in FIG. 9B.
Continue to rise while maintaining the vertical positional relationship shown in (). Also, the stopper 9 that descends together with the rod 22 is attached to the middle holder 1.
moving away from 2. On the other hand, since the upper holder 6a is pushed down as the rear piece 22a descends, the guide needle 10 integrated therewith also descends by the same distance. If the above-mentioned vertical movement continues further, the state shown in FIG. 9C will be reached.

The vertical positional relationship of each thread at this time is the same as that shown in FIG. 5C. The movements of the above parts are summarized in Table 4.

When the weft insertion is completed, in the next cycle, the front piece 24a descends from the position shown in FIG.
2a begins to rise.

Accordingly, since the lower holder 6b is biased by the spring 8, it descends following the lower front piece 24b, and the pivot point R above it also descends. Since the middle holder 12 is drawn toward the lower holder 6b by the tension spring 18, it descends together with the lower holder 6b, and the pivot point P above it also descends. That is, the shaft supports P and R descend while maintaining the vertical positional relationship shown in FIG. 9B. On the other hand, as the rear piece 22a rises, it is urged upward by the spring 8. Since the upper holder 6a also rises following this, the guide needle 10 integrated therewith also rises. In addition, along with this
2 and stopper 9 also rise. If this vertical movement continues further, the rising stopper 9 will eventually hit the bottom surface of the holder 12 as it descends. This state is the same as that shown in FIG. 9B. When the vertical movement continues, the lower holder 6b
is still descending, so the pivot point R above it is also descending. On the other hand, since the middle holder 12 is pushed up by the stopper 9 on the rod that is rising together with the rear piece 22a, the pivot point P thereon now begins to rise. That is, the pivot point P,
R performs a second relative movement. Of course, the guide needle 10 continues to rise during this time. When the middle holder 12 further rises and the lower holder 6b descends, the gap between them becomes D, returning to the state shown in FIG. 9A, returning to the neutral state shown in FIG. 9A, and the shed is completely closed.

Further, as the front piece 24a continues to fall and the rear piece 22a continues to rise, the middle holder 12 is pushed up by the stopper 9, so the pivot point P rises, and the lower holder 6b is pushed up by the rear piece 22b. The pivot point R also rises by the same distance.

That is, the shaft supports P and R rise while maintaining the vertical positional relationship shown in FIG. 9A. On the other hand, the guide needle 10 is attached to the upper holder 6.
a is pushed down by the descending front piece 24a, so it descends. If the above-mentioned vertical movement continues further, the state shown in FIG. 9D will eventually be reached.

The vertical positional relationship of each thread at this time is the same as that shown in FIG. 5F. The movements of the above parts are summarized in Table 5.

The contents of the first and second relative motions described above are summarized in the sixth section.
Shown in the table.

The contents shown in Table 6 are exactly the same as those shown in Table 3.

Therefore, the left and right sorting guides 16 and 17 swing at each timing in exactly the same way as in the first embodiment, that is, as shown in FIG. By guiding as shown in Figure 7, the edge of the twisted tissue as shown in Figure 7 is obtained. As is clear from the above explanation, the following effects can be obtained according to the present invention.

(a) Because the so-called kite method was used, in which the udon sutra is reapplied to the earth sutra every time, the rim of the ear is extremely strong.
The overall structure is small and simple.

(b) Other than the swinging of the distribution guide, the only movement of each member is vertical movement using the opening movement, so there are fewer movable members and the device is highly durable.

(c) Since the distribution guide swings, each yarn guiding hole moves along a circular orbit.

Therefore, the portion of the thread guide hole that comes into contact with the thread changes, making it difficult to guide the thread. Therefore, not only the life of the parts is extended, but also thread fuzz and thread breakage are significantly reduced. (d) In order to drive the distribution guide, the movement of the related members is simple and not unreasonable because the movement is performed only by reciprocating up and down.

Therefore, the device operation can sufficiently follow the high-speed operation of the loom, and the number of strokes can be increased relatively easily. (e) Since each part of the device can be seen and touched from the outside, it is not only easy to discover failures, but also easy to maintain.

(f) When sorting the threads for kneading, the threads are not subjected to excessive bending, so the threads are not damaged.

(g) Create two distances between the pivot points PR using the equivalent momentum D, and use this to create a very small number of parts 2, 1.
4a, 14b, 16, and 17 are used to allocate the sutras, so the structure is very simple.
