Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to an improvement of a warp thread discharging device in a warping machine, and more specifically, to an improvement of a warp thread discharging device in a warping machine. This invention relates to a tension-balanced warp unwinding device that eliminates the warp loosening phenomenon that conventionally occurs unavoidably by skillfully balancing the tensions of the new and old warp rows, which change according to the movement of the twill. This is a truly useful device for succession work.

[Prior art and problems to be solved]

A new warp row A and an old warp row B aligned and suspended by slide clips 1 and 1' are transferred to a pair of upper and lower new warp twill dividers 3 and 3' and an old warp twill divider which are attached to the warping machine main body 2. 4,4
The new and old warp threads located at the edges of the new and old warp rows A and B are divided into new and old warp threads by reciprocating the new and old warp threads by the drive of the warping machine main body 2. A Ryukyu machine that separates and steers each rod one by one is conventionally well known.

However, in this case, as is clear from the illustrations in Figure 1 A to I, the twill branches 3, 3', 4, and 4' are rotated and the twilled warp threads are alternately bent there.・Since the straight stretching operation is performed, the warp threads on the straight stretched side tend to become slack, and it is difficult to accurately steer the warp threads at high speed, especially when processing threads with poor elasticity such as polyester threads. It wasn't the most difficult thing to do.

In particular, recently, the present applicant has proposed a ``device for dispensing threads in a joining machine'' (Tokukan Sho 57-51 I No. 9) and a ``device for selectively moving separated sewing threads in a joining machine'' (Sho 57-51). 5785), a crank-shaped twisted twill birch is used, and in order to bend and straighten the new and old warp yarns at the convex and concave portions of the crank-shaped twill birch, these The range of change in tension that occurs in the warp threads is large, and the slack in the warp threads must also increase accordingly.

Moreover, in the latter "...separation warp selection movement device", the new and old warp threads pulled out by Ayabu Azusa must be inherited by a thread carrying needle with a hook, so the above-mentioned warp threads must be transferred. Slackness is a major cause of hindering the efficiency of succession work. The present invention has been made in order to solve the above-mentioned drawbacks that have been pointed out regarding the warp thread discharging device of a warping machine. The present invention aims to provide an innovative warp thread stripping device that can draw out warp threads and accurately deliver them to a knotter section.

[Technical means adopted to solve the problem]

To illustrate and explain the technical means adopted by the present inventor in order to overcome the above-mentioned technical problem, the warping machine is equipped with a ``tension-balanced warp line drawing device'' consisting of the following mechanism. be.

That is, in the present invention, a new warp row A and an old warp row B aligned and suspended by slide clips 1 and 1' are transferred to a pair of upper and lower new warp twill branches 3 and 3' installed in the warping machine main body 2. and old thread twill branches 4 and 4', respectively, and these new
By reciprocating the old yarn luster separation birch by the drive of the warping machine main body 2, the new and old warp yarns located at the edges of the new and old warp rows A and B are separated one by one and harvested. In the warp general machine to be taken out; the warp rows A and B are inserted between the slide clips 1 and 1' and the new and old yarn twill branches 3 and 4 that are repositioned upward.
Bare guides 8 and 9 are provided protruding from the main body 2 of the passing machine, and each of the guides 8 and 9 has a narrow width at the tip and is inserted into the main body 2 of the passing machine. The tension adjusters 5, 6 are formed into a tapered shape whose width gradually increases toward the direction of the tension adjuster 5, 6, and are oriented in a substantially horizontal state.
The narrow part of the tip of 6 is pivoted to the corresponding guide rods 8 and 9, respectively, and below the adjusters 5 and 6, the warp thread rows A and B can be introduced in an aligned state, respectively. By interposing the warp holder 7 having yarn guiding slits 71 and 72, the warp yarn rows A and B can be moved in accordance with tension changes in the warp yarn rows A and B caused by the operation of the d twill branches 3, 3', 4, and 4'. The wide rear portions 51, 61 of the adjusters 5, 6 swing in a substantially horizontal direction around the pivots P, P, so that the tensions of the warp yarn rows A, B, which are divided into twills, are balanced. The present invention relates to a tension-balanced warp feeding device characterized by the following features.

〔Example〕

The present invention will be explained in more detail with reference to the illustrated embodiments.
Specific examples of the tension adjusters 5, 6 and the warp holder 7, which constitute the main parts of the present invention, are shown in FIGS. 3 to 6.

In the illustrated example, the tension adjusters 5 and 6 are made of tapered plates having a substantially isosceles triangular overall shape, and the tension adjusters 5 and 6 are made of tapered plates whose overall shape is approximately an isosceles triangle. The narrow portions at the tips are pivoted P, P, so that the rear portions 51, 61 swing to the left and right in response to fluctuations in the tension differential pressure between the new and old warp threads.

Guides 8 and 9 are new to tension adjusters 5 and 6.
It is provided so that the old warp rows A and B are guided smoothly in a state where they are divided into twills, and the lower ends of the guides 8 and 9 shown in FIGS. 2 and 3 are connected to the upper twill. It is connected to the tip portions of birches 3 and 4 so as to be slidable in the axial direction. In the figure, reference numerals 52 and 62 are stoppers that restrict excessive rotation of the adjusters 5 and 6, and are useful when transporting the aircraft. The warp holder 7 is located below the tension adjusters 5 and 6 and is fixed to the frame of the stitching machine main body 2.

In the illustrated example, the warp holder 7 is a square-shaped metal plate with two thread guiding slits 71 and 72 formed therein. The thread guide slits 71 and 72 of the warp thread holder 7 are configured to have slightly wider entrance portions so that the warp threads can enter smoothly, and are smoothed so that the threads can easily slide. Although the apparatus of the present invention is generally constructed as described above, the present invention is by no means limited to the illustrated embodiments, and various modifications can be made within the scope of the claims. The tension adjuster may have any shape as long as it can enter into the divided warp rows and spread them smoothly laterally.
Furthermore, the present invention is applicable not only to the segmental type warp splicing machine as shown in FIG. Needless to say, it can also be applied to machines. [Operations and Effects of the Present Invention] As explained above, in the present invention, the new and old warp rows A divided into twills are placed between the slide clips 1, 1' and the twill portions 3, 4 which are displaced upwardly. Tension adjusters 5 and 6 are provided which swing in response to changes in the tension pressures of warps A and B, respectively, and new and old warp rows A and B are introduced and held in an aligned state below these tension adjusters 5 and 6. We are currently exploring a configuration in which a warp holder 7 is provided to accommodate the warp threads.

Therefore, in the relay machine to which the present invention is applied, the reciprocating rotation of the new and old thread twill branches 3, 3' and 4, 4', as illustrated in Figs. Even if the new and old warp rows A and B are bent and straightened, and the tension of the ridges a and b on the straightened side is reduced, the new and old warp rows are kept aligned and held by the warp holder 7. Tension adjuster 5
, 6 immediately pivot toward the warp yarns a and b, where the tension pressure has decreased, and balance the tensions of the old and new warp yarn rows A and B that are in contact with both sides of the adjusters 5 and 6, so that the warp yarns This ensures that there is no slack in the thread during unwinding. As described above, according to the present invention, it is possible to completely eliminate the problem of thread loosening during warp thread discharging, which was thought to be unavoidable in this type of warping machine, and also to solve the problem. It uses a driven tension adjuster that skillfully utilizes changes in the tension pressure of the warp thread body to balance the tension dynamically without using a passive forcing mechanism, so there is no force on the warp threads. It is possible to process in ideal conditions without applying stress, and from a mechanical perspective, it can be realized with an extremely simple structure, making it inconvenient to make simple adjustments and almost never causing failure. The following advantages can be obtained.
