Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for forming piles of different lengths at arbitrary locations on a fabric.

[Conventional technology and issues]

Conventionally, there are three methods for creating piles: the reed beating method in which the reed is moved back and forth, the sword beating method in which the entire botton is moved back and forth, and the method in which the weave is moved back and forth, which is often used on high-speed looms.
There is a way.

Since the conventional method for removing piles is usually the beating method, the method and apparatus thereof will be explained below.

FIG. 4 is an explanatory diagram of the main parts of the device.

Reference numeral 1 denotes a reed, and as the modified triangular cam 2 rotates, its motion is sequentially transmitted to a cam roller 3, a cam lever 4, a vertical rod joint 5, a vertical rod 6, and a stop rod arm 7, and is moved forward and backward by the stop rod arm 7.

In the most commonly adopted 3-bit method, as shown in the explanatory drawing for pile removal in FIG. 5, one weft yarn is inserted in one rotation of the loom, and three weft yarns (■, ■, ■) are input in three rotations of the loom. ■, ■, ■ of the cloth in the drawing are those with the reed 1 open, and ■■■■■■ on the left is the part where the pile P is formed by being pushed by the reed 1. Two lower warp threads that become the core of the fabric x
, of y, X passes from above the weft ■■, under ■, and emerges on top of ■■. The other lower warp y comes out above the lower shell ■ of the weft ■■ and passes under ■■ again. Top pile yarn a among pile yarns
passes under the upper shell ■ of the weft ■, passes over ■ and the next ■, and passes under the next ■. The back pile yarn passes under the weft ■, comes out on top of ■, passes under ■■, and comes out again on the next ■.

Since the reed 1 is opened from the front X-line and located at the Y-line, the front pile yarn a and the back pile yarn A extend horizontally between the weft yarns ■ and ■.

The modified triangular cam 2 of the above device rotates, and while the two protrusions distant from the shaft 2a, that is, the long diameter parts △1 and △2, are in contact with the cam roller 3, the cam lever 4 and the vertical rod joint 5 are in contact with the cam roller 3. is engaged,
The reed 1 remains open by the length of the pile, and when the cam roller 3 comes to the protrusion near the shaft 2a of the deformed triangular cam 2, that is, the short diameter part △3, the cam lever 4, vertical carro, 7 joint joint 5 The engagement with the reed 1 is released, the vertical joint 5 is pulled by the spring and moves, and the movement
The reed 1 is washed up to the front of the fabric, and a pile P is formed by the front and back pile yarns a and b between the weft yarns -. - The length of the pile is determined by adjusting the opening amount of the reed 1 using an adjustment screw (not shown) of the vertical lot joint 5.

Since tension is applied to the lower warp threads x and y, they do not form a pile even when the reed 1 is closed.

The relationship between the above prefectures is shown in Figure 6 in an organizational chart. The symbol ■■■ on the right side of the figure indicates a weft, the O mark and the cross indicate that the weft passes over the weft, and the blank mark indicates that the weft passes under the weft.

As shown in FIGS. 8(A) and 8(B), in the conventional sword driving method, the hair pulling lever 21 and the hair pulling claw 22 are attached to the same hair pulling rod 23, and the sword 24 is attached to the same hair pulling rod 23.
is rotatably attached to the bottom shaft 25 at its lower end, and a reed 26 is provided at the upper end on the opposite side,
A hair removal sword 28 is attached to the upper end of the hair removal sword pin 27.
A connecting slot 30 is rotatably connected to a crank 31 by a connecting pin 29 in the middle of the hair removal sword 28 .

32 is a cam having a long diameter part and a short diameter part, and as shown in FIG. When pressed, the tip of the hair removal claw 22 attached to the same hair removal port/gutter 23 is also lifted, and the tip supports the lower end of the hair removal sorter 28, and the connecting port/gutter 30 is moved forward by the crank 31. As it extends to the left (in the figure) and pushes the hair removal sword 28 with the connecting pin 29,
The hair removal sword 28 is connected to the sword 24 with the hair removal sword pin 27.
Press the top edge of the. At this time, since the lower end of the hair removal sword 28 is supported by the hair removal claw 22, the upper end of the sword 24 is strongly pushed, and the reed 26 provided at the upper end of the sword 24 makes a large reed beating movement to reach the weaving area. do.

As shown in FIG. 8(B), when the long diameter part of the cam 32 separates from the hair removal lever 21 and the short diameter part comes upward, the hair removal lever 21 is not pushed up by the cam 32, so the hair removal opening 7 23 is the axis, and the hair removal lot 23
Since the tip of the hair pulling claw 22 attached to the handle also lowers,
The lower end of the hair removal sword 28 is released from being supported by the tip of the hair removal claw 22, and even if the hair removal sword 28 is pushed by the connecting slot 30 due to the rotation of the crank 31, the upper end of the hair removal sword 28 is not supported by the tip of the hair removal claw 22. The push is the 8th
The reed 26 moves only slightly compared to the case in Figure (A), so the reed 26 does not move all the way to the fabric. The second stage of the bristle claws 22 is for ground weaving, so its explanation will be omitted.

In this device, the weft threads ■ and ■ push the hair pulling lever 21 with the short diameter part of the cam 32, and at that time, the lower end of the hair pulling sword 28 separates from the hair pulling claw 22 as described above. The tip part does not act on the hair removal sword 28, and the weft threads ■ and ■ are beaten with a gap from the fabric (loose pick), and the weft thread ■ is inserted and the long diameter part of the cam 32 pushes the hair removal lever 21. The lower end of the hair removal sword 28 is supported by the hair removal claw 22, and the upper end of the sword 24 is pushed greatly with the upper end of the hair removal sword 28 to push the reed 26 to the weaving area to form a pile.

All conventional methods for producing piles, including the conventional reed beating method and sword beating method described above, can only produce piles of the same length over the entire width of the fabric in one pile yarn. , it is not possible to produce piles with different lengths.

In order to force the length of the pile to change, it is possible to use a method in which a certain vertical width is made into a long pile, and then a certain vertical width is made into a short pile, but it is not possible to make piles of different lengths and short ones on the same horizontal line. Can not. In other words, it is possible to form a pattern with linear long and short piles across the width of the fabric, but since it is not possible to create long and short piles on lines of the same width, it is not possible to form dotted or curved patterns with long and short piles on the fabric.

The present invention provides a method and apparatus that enables the formation of long and short piles on the same pile yarn, which could not be done with conventional pile methods, and thus the formation of piles of different lengths at any location on a fabric. The purpose is to

[Means to solve the problem]

In the pile method using the reed beating method, the sword beating method, and the method of moving the fabric front and back, the three weft yarns, the first, second, and third, inserted into the pile yarn and the lower warp are sequentially separated from the fabric fabric into short piles. Then, the fourth and fifth wefts are beaten in a place separated by a long pile from the woven fabric, the sixth weft is passed through, and the first to sixth wefts are beaten to the woven fabric. , select and form either short pile 2 or long pile 1 with 6 picks on one pile yarn.

A pile pulling device using the reed beating method uses a triangular cam that is attached to a rotating shaft and has three long diameter portions that form the vertices of an equilateral triangle, and members that are linked in sequence to transmit the movement caused by the rotation of the triangular cam to the reed. and a means for disengaging the triangular cam and the member that transmits the motion of the triangular cam to the reed without relying on the triangular cam; and two long-diameter parts mounted coaxially with the rotating shaft. a deformed triangular cam having one short diameter portion and a member that sequentially cooperates in order to transmit the rotational movement of the deformed triangular cam to the reed;
A B mechanism including a means for disengaging the deformed triangular cam and the member that transmits its motion to the reed without using the deformed triangular cam, and disengaging the engagement of either the A mechanism or the B mechanism. a control means for issuing a command to select and operate the means, the triangular cam and the deformed triangular cam are mounted on the same shaft, and each of the linking members with the reed of the A mechanism and the B mechanism is provided. The strobront arms of the above are connected by the same shaft, and a common reed is attached to the shaft, and the triangular cams of the A mechanism are connected to the three long diameter parts, and the two long diameter parts of the B mechanism are connected to the cams of the respective linking members. While the reed is in contact with the roller, the reed remains open, and when the short diameter portion of the modified triangular cam of the B mechanism comes into contact with the cam roller, the reed can be pushed to the front.

The method for producing long and short piles using the above-mentioned reed beating device is to pass three weft threads through the pile threads and lower warp threads one after another, and in the meantime, the control means disengages the reed from the B mechanism, and from the shaft of the reed mechanism to the tip. The reed is opened by rotating a triangular cam with three protrusions of equal length and the spacing between the tips, and then the control means disengages the reed from the Ata structure, and the 4th, 5th, and 6th weights are sequentially opened. The three wefts are passed through, and between them, a modified triangular cam having two major diameter parts and one minor diameter part with equal lengths from the axis of the B mechanism to the tip is rotated to pass the fourth and fifth weft threads. In the case of , the reed is opened at the two long diameter parts, then the sixth weft is passed through, and the reed is moved to the weaving front using the short diameter part of the modified triangular cam, and the pile threads, lower warp and The six weft yarns are pushed in the weaving direction, and one long pile or two short piles are selectively formed with six bits per pile yarn.

In the pile pulling device of the sword driving method, the lower end of the sword with a reed on the top is rotatably attached to the botton shaft, and the upper end of the pile pulling sword is rotatably connected to the top with a connecting slot connected to the crank. In the fabric sword driving device rotatably fixed to the upper part of the sword, a bristle claw with one end rotatably attached to a bristle rod and a tip formed in three stages, and a lower surface of the bristle claw. A hair removal lever that is in contact with and rotatably attached to the same hair removal rod, a spring that biases the tip of the hair removal lever downward, and a cylinder provided below the tip #1 of the hair removal lever. and a control means that makes it possible to selectively support the lower end of the hair removal sword at each stage of the tip of the hair removal claw, or to release the support thereof, by expanding and contracting the shaft of the cylinder. While threading the first, second, and third weft threads, the shaft of the cylinder lifts the hair removal lever, and the hair removal claw is also lifted accordingly. Support the lower end of the sword and reed the short pile away from the fabric, then pass the fourth and fifth weft threads, while lowering the shaft of the cylinder to lower the hair removal lever and raise the hair removal claw. Make sure that it does not touch the bottom end of the bristle sword,
The long pile is separated from the fabric by reeding, and then the 6th weft is passed through, and the shaft of the cylinder is used to lift the bristle rod, and the first tier of the bristle claw is attached to the bristle sword. With the lower end supported, the first to sixth weft yarns are brought together by a reed to the front of the weave to form a short pile 2 and a long pile 1.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

First, a double 3-bit type (6-pick irregular terry motion type) device, which is an improved version of the conventional 3-pick type reed beating device, is shown in FIGS. 1(A) and 1(B).

In the A@ structure shown in FIG. 1(A), instead of the deformed triangular cam 2 in the conventional device, the distances of the tips of the three protrusions to the shaft 2a are equal, and the shape connecting the tips is an equilateral triangle. A triangular cam 9 is used. The three tips are indicated by symbols △1, 2, and 3 as shown in the drawings in correspondence with the weft thread numbers to be explained later. The structure of the member that transmits the motion of the triangular cam 9 to the reed 1 is the same as that of the conventional example, but in addition to this, there is also a control means (not shown) that pulls the Harch Carlo 7 joint joint 5 in the direction D according to a command from a dobby machine or a jacquard machine. (with only an arrow displayed).

Mechanism B shown in FIG. 1(B) has the same configuration as the conventional three-pick beating method device. The three tips are indicated by symbols △4, 5, and 6 in correspondence with the weft thread numbers which will be explained later. In the figure, Δ6 is the short diameter portion.

Similarly to the A mechanism, the B mechanism is also provided with a control means (not shown, only the arrow is shown) that pulls the vertical rod joint 5 in the D direction in response to a command from the Dobby machine or the Jacquard machine.

The triangular cam 9 of the mechanism and the modified triangular cam 2 of the Bt & mechanism are attached to the same shaft 2a. Further, in the A mechanism and the B mechanism, the respective stop rod arms 7 are connected by the shaft 11 of one reed 1.

A method for putting out piles using this device will be explained using the double 3-bit method (6-pick irregular terry motion method).

The double 3-bit method is a method in which three weft yarns are repeated twice in one set of 6 bits as one movement.

In Figure 2<A) and (B), those wefts are
Represented by ~■.

The lower warp X passes over the weft thread ■■■■■, passes under the ■, returns to the top of ■~■, and repeats. The lower warp y is ■■■■
It passes under ■, emerges above ■, and passes under ■～■ again.

As shown in Figure 2 (A), the front long pile yarn C is the weft
Pass over ■■, wrap under ■, exit above ■, and repeat the above process again.
Exit above, pass under ■ and ■, exit above ■, pass under ■, then go under ■ again, exit above ■, and repeat the above.

As shown in Figure 2 (B), the back long pile yarn e has a weft yarn ■
Pass under ■■■, exit above ■, pass under ■, and repeat the above.

FIG. 3 is an organization chart of a pile removal method that combines the above-mentioned FIGS. 2(A) and (B). Figures 2 (A) and (B) above
), the weft is not beat with three picks of ■■■, and after three picks of ■■■ have passed, beating is carried out. Therefore, Orimae XiJ! Between the reed position WY line, the long and short pile yarn cdef is stretched horizontally, and when it is reeded,
The pile yarn is pushed to form a pile P as shown to the left of the front X-ray. As shown in FIG. 2C, it is also possible to combine the long pile yarn C of FIG. 2(A) with the short pile yarn f of FIG. 2(B).

To perform the above-mentioned pile removal, the triangular cam 9 of the A mechanism in FIG. , insert ■. Meanwhile, in the mechanism B, the vertical rotor joint 5 is pulled in the D direction by the command from the dobby machine or the jacquard machine to disengage the cam lever 4 and the vertical rotor joint 5, and the movement of the deformed triangular cam 2 is transmitted to the reed. Make sure not to. After inserting the weft ■, B11
Release the vertical lot joint 5 of mechanism 1 from pulling in direction D, and conversely pull the vertical lot joint 5 of mechanism A.
is pulled in the D direction to disengage the cam lever 4 and the vertical rod joint 5, the weft thread is inserted, and the deformed cam 2 of the B mechanism in Fig. 2 (B) rotates in response to the weft thread. 4.5 sequentially pushes the cam roller 3 toward the long diameter part, and the cam lever 4 stops the movement of the Hart Carlo and 7F joint 5,
Reed 1 remains open. Next, the weft ■ is inserted, and the short longitudinal part △6 of the deformed triangular cam 2 of the B mechanism comes into contact with the cam roller 3, so the cam roller 3 moves in the direction of the shaft 2a and connects with the tip of the cam lever 4 and the vertical rod joint. The vertical joint 5 is pulled by the spring 10 and moves, and the movement is transmitted to the reed 1, which moves from the Y line to the X line, and the pile yarn cdef between y and x The lower warps X and y and the wefts ■ to ■ are pressed and woven to form a pile P. Next, the vertical rod joint 5 of the heave mechanism is released from being pulled in the D direction, and on the contrary, the vertical rod joint 5 of the B mechanism is pulled in the D direction, and the weft threads 1 to 2 are sequentially inserted again, and the above movement is repeated.

In order to form long piles and short piles in one pile yarn, the controller (not shown) is operated alternately for each rotation of the triangular cam 9 of mechanism A and the modified triangular cam 2 of mechanism B. If the vertical lot joints 5 of the A mechanism and the B mechanism are pulled in the D direction according to the command, long piles will be formed continuously, and then in order to form short piles, the vertical lot joints 5 of the A mechanism and the B mechanism are pulled in the D direction. The modified triangular cam 2 of mechanism B may be continuously rotated while the vertical rod joint is pulled in the D direction.

The above method and device have been described in terms of a double 3-bit method based on a 3-bit method and its device, but a double 4-pick method can be implemented by using the triangular cam 9 and the modified triangular cam 2 as a square cam and a modified square cam. I can do it.

In addition, fabrics with only short piles by operating mechanism A, and fabrics with only short piles by operating mechanism A,
It is also possible to make a woven fabric with only long piles by operating only the mechanism. In addition, by adding another B mechanism to the A and B mechanisms and adjusting the engagement between the vertical rod joint 5 and the vertical rod 6 of the added B mechanism, the BI & mechanism and the additional B mechanism can be combined. It is also possible to perform conventional pile driving.

The sword driving device according to the present invention has three stages of hair removal claws compared to the conventional device shown in FIG. 8, and uses a cylinder shaft instead of the hair removal cam. FIG. 7 is an explanatory diagram of the main parts of the device.

The tip of the bristle claw 33 has a two-stage member 33a and a single-stage member 33b stacked on top of each other to form three stages.
In order to adjust the distance between the tip of the vertical wall 40 of the third stage and the vertical wall 39 of the second stage of the member 33a, use the screw 3.
4 allows the mounting position to be changed. However, member 3
3a and 33b may be integrally formed, and in this case, a plurality of protruding claws having different distances may be prepared and replaced. Three cylinders 35, 36, and 37 having the same shaft length are arranged in place of the cam with a step below the hair removal lever 21. When the shaft of the cylinder 35 installed at the highest position extends and lifts the hair removal lever 21, the tip of the hair removal sword 28 comes into contact with and is supported by the vertical wall 38 of the first stage of the hair removal claw 33. When the shaft of the cylinder 36 at the middle position is extended, the vertical wall 39 of the second stage of the hair removal claw 33 is extended, and when the shaft of the cylinder 37 at the lowest position is extended, the hair removal claw 3 is extended.
When the shafts of all the cylinders are retracted, the tip of the sword 28 comes off from the hair pulling claw 33.

A spring 41 is attached to the hair removal lever 21, and urges the hair removal lever 21 downward.

By using cylinders 35, 36, and 37 with shafts of different lengths, it is not necessary to provide each cylinder at a stepped position.

Further, if a cylinder such as a hydraulic cylinder that can adjust the degree of expansion and contraction of the shaft is used, three cylinders are not required, and only one cylinder is sufficient.

The method of operation of this device will be described below with respect to pile removal shown in FIGS. 2 and 3.

Weft ■, ■, ■ by dobby or jacquard signal
, extend the shaft of the lowest cylinder 37 among the three cylinders, lift the hair removal lever 21 a little, and insert the lower end of the hair removal sword 28 into the vertical position of the third stage of the hair removal claw 33. It is supported by being brought into contact with the wall 40. At this time, even if the rotational movement of the crank 31 is transmitted to the sword 24, the distance between the lower end of the hair removal sword 28 by the hair removal claw 33 and the sword 24 opens only a little, so that the reed 26
makes a small movement and hits a short pile away from Orimae.

When the wefts ■ and ■ are inserted, all cylinders receive a signal and the shafts are housed, and the hair removal leno\-21 is connected to spring 4.
1 and lowers, and at the same time the hair pulling claw 33 also lowers,
The lower end of the hair removal sword 28 is separated from the hair removal claw 33 and the reed 2
6 is a long pile away from Orimae.

When the weft ■ is inserted, the shaft of the cylinder 35 provided at the highest position is extended and the hair removal lever 21
is lifted and the lower end of the hair removal sword 28 is supported by the first stage vertical wall 38 of the hair removal claw 33. At this time, crank 31
Due to the rotation of the blade, the distance between the lower end of the hair removal sword 28 and the sword 24 becomes wider, so the upper end of the hair removal sword 28 is strongly pressed by the rotation of the crank 310, and the reed 2 is rotated.
6, the weft yarns ■ to ■ are brought up to the weaving front, and one pile yarn is formed by selecting either short pile 2 or long pile 1 with 6 picks.

By adjusting the expansion and contraction of the cylinder shaft by the control means,
It is also possible to form only long piles or only short piles in one pile yarn.

[Effect]

For the reed, up to three weft yarns ■, ■, and ■ are reeded at a place where the end pile is separated from the woven fabric, and the weft yarns ■ and ■ are reeded at a place where the long pile is separated from the woven fabric, and the weft yarn ■ is reeded. ■～■
The weft yarns are brought together to the fabric front, and either short pile 2 or long pile I is selected and formed with 6 picks on one pile yarn.

In the reed beating device, the control means that pulls in the D direction in response to a command from the dobby machine or the jacquard machine makes it possible to select and transmit the motion of the triangular cam of the heave mechanism or the modified triangular cam of the Bfi mechanism to the reed.

The tips of the three protrusions of the triangular cam of the A mechanism maintain the engagement between the cam lever and the vertical rod joint to open the reed from the front.

The two long diameter parts of the modified triangular cam of mechanism B maintain the engagement between the cam lever and the vertical rod joint to open the reed from the front, and the one short diameter part maintains the engagement between the cam lever and the vertical rod joint. By disengaging the reed and moving the reed to the fabric, the six weft yarns are brought up to the fabric front, and one pile yarn can be formed by selecting either short pile 2 or long pile 1 with 6 picks. do.

In a sword striking device, the cylinder adjusts the degree of extension of its shaft to select the degree of elevation of the hair removal lever.

The tip of the three-stage hair removal claw is raised and lowered by raising and lowering the hair removal lever, the lower end of the hair removal sword is supported by the third step, and the tip of the hair removal claw is reeded at a point a short pile away from the fabric. Do not support the lower end of the barbage sword and beat the reed to a long pile away from the weaving area, and use the first stage of the barbage sword to support the bottom end of the barbage sword and beat the reed to the weaving area. , select and form either short pile 2 or long pile 1 with 6 bisok on one pile yarn.

(Effects) According to the pile producing method according to the present invention, it is possible to form either long or short piles at any location on a single pile yarn, and therefore, it is possible to form piles of different lengths at any location on the fabric. According to the apparatus of the present invention, the above-mentioned pile removal method is possible, the structure is simple and the apparatus does not require much cost, and Conventional equipment can be easily modified at low cost.
