Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an automatic aze removing device for warp warping.

[0002]

2. Description of the Related Art Warp warping is different from general sheet warping for loom, and involves winding a yarn into a bundle as a pre-process for dyeing the yarn. In that case, in order to easily separate the fibers after dyeing, one warp yarn is alternately sewn at predetermined intervals in the middle of the warp warp and a string (string) is passed in the lateral direction. This string is called Aze thread (ridge thread). In the present invention, the string is used as a synonym for aze yarn.

[0003] Conventionally, such an operation is called "aze removal", and all operations are performed manually. Therefore, each operation for removal has a time of 2 to 3 minutes and a set warp of about 5500 m takes 20 to 30 minutes. During that time, the machine had to be stopped, which required manpower and was inefficient in production.

The present inventor has
A study was conducted for the purpose of developing a device that can be continuously and automatically carried out without relying on human labor. First, Japanese Patent Laid-Open Nos. 3-832 and 4-202826
I am proposing in the issue.

In the former structure, without a special warp tension adjusting device, one side of the comb-shaped screen, which moves up and down as a whole, is arranged on both sides of the rear warp surface of the comb-shaped screen. In this case, a dividing rod and two string-placing rods that come in and out, and two string feeders and a string-connecting device are provided for the moving ends of the string-placing rods, respectively.

The latter structure is a further simplification of the former device, in which one pair of separating rods, string passing rods, string feeders and string connecting devices, which have been paired up to two, is addressed to one. The structure has been modified. That is, the length of the slit is repeated, and the comb-shaped screen that moves up and down as a whole and the traveling frame that is placed beside the warp surface behind the comb-shaped screen move from one side attached to the moving frame to the warp surface. On the other hand, one dividing rod that goes in and out, and one string passing rod that goes in and out of the warp surface further behind
One string feeding device provided at the moving end of the string threading rod, one string connecting device provided at the base end of the string passing rod, and a string equalizing the string passed through the warp yarn surface to the yarn surface width. A device is provided. The string leveling device used in this device consists of upper and lower parts that are placed on top of the string that passes through the warp surface and that penetrate the warp surface and feed it sideways and a plurality of leveling plates that swing. It was

[0007]

The automation of the aze removing device was almost achieved by the above-mentioned two proposed mechanisms and continued to operate. However, during each operation, the warp feed is stopped to perform the operation. In addition, there is a drawback that the yarn feeding speed does not increase and the time required for each operation increases considerably, and further shortening of the time remains as a problem to be solved.

[0008]

The present invention has been made to solve the above problems, and the gist of the present invention is to supply a predetermined number of yarns from a large number of raw yarn cheeses and to form a comb-shaped screen. In the warp warping, in which every other thread warped by the yarn is alternately drawn and aligned in a bundle and wound up, an aze removing bar and a tension bar are provided between the diameter adjusting roll and the comb-shaped screen. The split bar is two parallel rods rotatable in the plane perpendicular to the axis, and a string leveling device is provided below the warp surface and is provided in a direction substantially perpendicular to the moving direction of the warp thread to make a plurality of rotations. Another object of the present invention is to provide an automatic aze removing device for warp warping, which is characterized in that a plurality of dividing plates are arranged so as to rotate sequentially on a shaft.

[0009]

[Function] The squeeze bar and the tension bar are for equalizing the tension of the sizing surface from the sizing roll, and are an alternative to the conventional threading bar. This is to separate the fibers so that the separating rod can be easily inserted before performing the operation, but this device, which increases the tension of the warp, makes this unnecessary, and the next aze removal operation can be performed continuously. As a result, the time required for thread tension was reduced to about 1/3.

The dividing rod is to secure an opening portion of the diameter adjusting thread surface necessary for inserting the stringing rod. However, this device is thinner than the conventional one dividing rod, and therefore the opening is made. It is easy to put in the part, and after inserting it, rotate 90 ° to widen the gap between the upper and lower diameter adjusting thread faces to facilitate the insertion operation of the string threading rod, thereby reducing the opening movement and the moving distance of the dividing rod. Shorten the required time to enable operation during continuous movement.

In the string leveling device, a plurality of separating plates are rotated from below the warp in an oblique direction to enter the warp surface so as to enter the warp surface. Roll it in and level the entire warp.

Embodiments of the present invention will now be described in detail with reference to the drawings. 1 is an overall side view of the automatic aze removing device, FIG. 2 is a plan view of the same, and FIG. 3 is an enlarged view of a portion P in FIG. The warp warping is performed by a raw yarn supplying device (not shown), an automatic aze removing device of the present invention shown in FIGS. 1 and 2, and a warp winding device (not shown). The raw yarn supplying device is a conventional device including a cradle for a large number of raw yarn cheeses and a yarn breakage sensor for each of the supplied yarns. Further, the warp winding device after warping is also a conventional device having a structure of a traverser and a winding roll for thickening and winding on two parallel drive rolls.

As shown in FIG. 3, the automatic aze removing device has a guide roll 2 and a warp roll 3 for aligning a large number of warp yarns 1 from the raw yarn supplying device in a plane, and subsequently,
Aze removal bar 4 and fixed bar 5, which is a tension bar 5.
There are 1,53, a vertically movable bar 52 and its cylinder 54, and a thread pressing bar 6 and a comb-shaped screen 7 are behind it. Below the aze removing bar 4, a float suction port 8 is arranged in the vicinity of the warp surface in order to remove the float attached to the warp by suction.

In the aze removing bar 4, a cauldron-shaped bar 41 whose front portion in the warp traveling direction is inclined downward can be moved up and down by an upper cylinder 42. The tension bar 5 is a rod-shaped bar
A cylinder 54, which is provided upward from below, can move up and down. The aze removing bar 4, the tension bar 5, and the thread pressing bar 6 further make the warp surface tension from the warp roll uniform and improve the open state. Table 1 shows these movements.

[0015]

[Table 1]

The reed consisting of the comb-shaped screen 7 has long and short slits 71, 72 for passing a single thread, and is supported by guide grooves on both sides so that the whole moves up and down, and a cylinder 73 provided on both left and right sides. Driven by. These eliminate the need for conventional threading bars and allow continuous operation without stopping the equipment.

Next, the dividing rod 9 will be described. The dividing rod 9 is a cylinder 91 and a base 9 as shown in FIGS.
2 is movable in the front-back direction of the warp progression, and
As is clear from 4 and 5, two parallel rods 93, 93 are fixed to a rotating shaft 95 by a cylinder 94 standing upright from a dividing rod base 92 so as to rotate in a plane perpendicular to the shaft. As shown in FIG. 2 (b), this dividing rod 9 is for securing the opening portion of the warp surface necessary for inserting the string passing rod 11, but it is thinner than the conventional one dividing rod. It is easy to put it in the opening with, and after inserting it, by rotating it by 90 °, the opening interval of the upper and lower warp surfaces is greatly expanded, and the string threading rod 11 explained next.
By facilitating the insertion operation of the slot, the opening movement can be made small, the moving distance of the separating rod 9 can be shortened, and the required time can be shortened. The movement of the dividing rod 9 is such that when the two rods 93, 93 are in the horizontal state, the dividing rod 92 enters the warp surface by the operation of the reciprocating cylinder provided in the slide base 96, and is rotated vertically by the cylinder 94. The cylinder 91 is moved toward the comb-shaped lead 19 to facilitate insertion of the string passing rod 11.

The stringing rod 11 is shown in FIGS. 2, 6 and 7, and has a rotary solenoid 12 at its base, a long operating rod 13 is provided from its rotary shaft, and two holding pieces at its tip end have a base. A clipper 15 having a structure in which the operating rod 13 is connected to a link 14 that is axially supported and is provided in a scissor shape and connects the both.
There is. When the spacing between the upper and lower warp surfaces is widened by the dividing rod 9, this string passing rod 11 enters into it, and the aze string 17 supplied from the aze string feeder 16 provided at the front in the traveling direction is clipped by the clipper 15 It is possible to pass the aze string alternately between the warp yarns which are raised and lowered by gripping with, and by retracting the string passing rod 11. The stringing rod 11 moves back and forth because the stringing rod base 111 moves back and forth by the operation of the reciprocating cylinder in the slide base 112. The cylinder 18 can also move back and forth in the traveling direction of the warp. The aze string feeder 16 is configured to supply a predetermined number of warp yarns from a plurality of yarn supplying cones in a string form. Threaded aze strings are connected by a string connecting device 24.

In front of the stringing rod 11 is a lead 19 seen in FIGS. This is provided in the shape of a vertical comb blade in order to guide the aze string passed through the bundle of warps onto a plurality of equalizing plates 22 described later. A base 192 of the lead 19 is provided with a lead front-rear cylinder 191 so as to be movable back and forth, and is moved on rails 193, 193 provided in parallel with the apparatus main body. This lead 19 is shown in FIG.
(b) As shown by the middle two-dot chain line, the string leveling device 20 is advanced to move forward.
Send it up.

The string leveling device 20 catches on the roller when the aze string comes out from the end of the warp bundle at the time of dyeing. Therefore, in order to prevent this, the string leveling device 20 is provided to arrange the aze string evenly. As shown in FIGS. 8 and 9, the structure is such that a leveling plate 22 is rotatably provided on a base 21 by a cylinder 23 vertically provided downward. The plurality of leveling plates 22 rise in order from one end to the other end, rise in order, rotate from below the warp in an oblique direction, and enter into the warp surface to enter the warp surface. Roll the aze cords at both ends into the warp plane and level the entire warp. When the last leveling plate is up, it will return downward.

As a result, one warp thread can be alternately sewn at predetermined intervals during the warp warp and the aze cord can be passed in the lateral direction. Then, it is fed to a warp winding device (not shown) via a dancer roller, a guide roller and the like.

The operation of the automatic aze removing device having the above structure is
