Abstract

PURPOSE:To obtain the subject apparatus, equipped with a wholly vertically movable comblike screen, having long and short slits and used for warping yarns, dividing rods rising and sinking in the warped yarns, treading rods, string feeders and string connectors, capable of automating rib stitching and improved in production efficiency. CONSTITUTION:A prescribed number of yarns are fed from a raw yarn feeder 1 composed of a frame 5 of many raw yarn reels 4 and a detecting sensor 6 for yarn breakage of respective fed yarns to an automatic rib stitching apparatus 2, paralleled in a plane with guide rolls 11 and 12 and then warped with a wholly vertically movable comblike screen 13 having repeated long and short slit lengths. Strings (rib stitch yarns) fed from string feeders (26a) and (26b) and string connectors (27a) and (27b) provided at the moving final end of string threading rods with dividing rods 24 and string threading rods (25a) and (25b) rising and sinking relatively to the warped yarn surface respectively from one side of running rails 22 and 23 arranged on both sides of the warped yarn surfaces at the back of the screen 13 are alternately threaded every other warped yarn and then paralleled in the form of a rope. The resultant rope is subsequently wound by a rope winder 3.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a new automatic grain removal device for a rope warper.

[Conventional technology and its issues]

Rope warping machines differ from general loom sheet warping machines,
As a pre-process for dyeing the thread, the thread is wound into a rope shape. In that case, in order to make it easier to separate the fibers after dyeing, strings are passed through the strings in the horizontal direction by sewing the aligned threads alternately at predetermined intervals during the warping of the rope. Thread). In the present invention, string is used synonymously with adze thread. Traditionally, this kind of operation was called ``removal of warping,'' and it was all done by hand, so it took 2 to 3 minutes for each removal operation, and it took 20 to 30 minutes for one set of warping, which averaged about 5,500 m. It required one person to stop the machine, and the production efficiency was poor.

[Means to solve the problem]

The present invention does not rely on manual labor in this adze removal work,
We are considering the development of koji making that can be carried out continuously and automatically.
It is completed. The key points of the solution are as follows: A predetermined number of yarns are supplied from a large number of raw yarn reels, and every other yarn warped with a comb-like screen is passed through the adze yarn alternately. In the rope warping machine, the slits are lengthened and shortened repeatedly, and the comb-shaped screen (13) moves up and down as a whole, and its moving warp is placed on both sides of the warp surface. Separating rods (
24) and string loop 4iIl (25a) (25b)
Then, the string connecting machine (2
6a) (213b) and string contact t! i machine (27a) (
27b). Here, for example, an air cylinder is used as the drive source for each member, and the start and end of the movement is detected by a limit switch.
A conventionally known drive control system using an electric automatic control circuit is used to open and close the air valve.

[Operation] The adze removal work using this device is carried out in the following order. First, the screen (13) is moved upward, and every other thread is divided into upper and lower surfaces depending on the length of the slits. Push out the dividing rod (24) with a cylinder, move it to the vicinity of the string passing rods (25a) (25b) on the running rail, and insert one string passing rod (2Sa) between the vertically divided series. Push it out with a cylinder, move it on a running rail to the position of the string tying machine (26b), and pass the string passed through the string passing hole (31a) through the series as the cylinder returns.Next, the comb-shaped screen ( 13) downward to open the series upside down, insert the dividing rod (24) again, move it to the mesh (15) position, and push out the string threading rod (25b) on the opposite side with the cylinder. Then, do the same operation as the previous string threading rod (25a), and when the two string threading rods (25a) and (25b) approach each other, insert the two strings passed between the lines that intersect each other, one above the other. The strings are cut at both ends using string tying machines (26a) (26b), and the strings are tied to each other using string connecting machines (27a) (27b) to form a ring shape, thereby forming a zebra thread and completing the zeze removal work. It is. (Example) Examples of the present invention will be explained in detail with reference to the drawings below. Fig. 1 is a plan view illustrating the operation of the automatic adze removing device of the present invention, and Fig. 2 is a rope warping machine equipped with the device. FIG. 3 is a side view of the same, and FIG. 4 is a view taken along arrow A-A in FIG. 3. As is clear from FIGS. 2 to 4, the rope warping machine It consists of three devices: a yarn supply device (1), an automatic adze removal device (2), and a rope winding device a (3). ) and yarn breakage detection sensors (6) for each supply system.The rope winding device a (3) after warping also has a traverser (7).
This is a conventional device configured with a take-up roll (10) that is thickened and wound on two parallel drive rolls (8) and (9). The feature of the present invention lies in the automation of removal of adhesion, and this automatic adhesion removal device M (2) first consists of guide rolls (u) (12 )
There is a comb-shaped screen (13).The comb-shaped screen (13) has long and short slits that pass through the threads.The comb-shaped screen (13) is supported by a guide groove on the south side so that it can move up and down, and an air cylinder (14 ) is provided with a vertical movement device. Next, there is a mesh (15) through which one thread is passed, and at horizontal movement intervals, tension rollers (16) (17)
(18), dancer roller (19), guide roller (
2o) are arranged in a substantially planar manner, and a grooved guide roller (21) is provided at the upper position in the reverse direction from here, and the planar series are assembled into a rope shape and sent to the rope winding device (3). It will be done. The process of removing the lint by passing the lint thread through the yarn at predetermined intervals is performed in this manner, and in the present invention, in order to automatically remove the lint, a device having the structure shown below is used. That is,
With respect to the comb-shaped screen (13) and the running rails (22) and (23) arranged on both sides of the warp surface behind it, there are rods (2

(26b) and string connectors (27a) (27b). There is a mesh (15) behind the comb-shaped screen (13), and the comb-shaped screen (13) and the mesh (15) align the series on one plane and advance. A dividing rod (24) between the comb-shaped screen (13) and the mesh (15) is arranged on the running rail (23) so as to move in and out of the yarn surface by a slide cylinder (29) and move back and forth. Also in front of Metush (15) is the running rail (2).
3) moves back and forth and slide cylinder (30a)
A string passing rod (25a) that goes in and out of the thread surface is arranged. A string threading rod (25b) is also supported by a slide cylinder (30b) at a position opposite to this string threading rod (25a) across the thread surface, and is arranged to move in the same way as the string threading rod (25a). It is. The operation of the automatic adhesion remover having the above structure will be explained with reference to FIG. 1. The operation order is shown below from 1 to 0, which are indicated by the same reference numerals in FIG. ■Activate the vertical moving device (14) of the comb-shaped screen (13) to separate the yarn into upper and lower parts.
