It has the function of applying tension to A.

Reference numeral 104 denotes width determining means, and a headless cylinder 158 is arranged on a base plate 156 on the width determining base 126. This rodless cylinder 1558 is composed of a guide rod 1660, a cylindrical moving member 162, and a force. The moving member 162 has a width determining member 1666 via a mounting plate 1664. take It is attached. A mounting member 168 is provided upright on the drum 1 12 side of the base plate 156, and an air cylinder 170 that faces downward is vertically provided above the mounting member 168. The transducer 1 is attached to the tip of the piston rod 1 72 of this air cylinder 170.

Although not shown, a release tape drive mechanism for feeding the release tape by a specified amount is provided, which enables various types of shedding at a predetermined shedding position.

According to this conventional partial warping machine, a warp group can be wound around a warping drum at a predetermined density and a required warping length, and various kinds of shedding can be performed at a predetermined shedding position. It has been very popular as a fully automatic partial warping machine (see International Publication No. WO 91 / 148,122).

By the way, in such a partial warping machine, in order to start winding the warp group of each section on the warping drum, the yarn starting end is held and fixed to the warping drum. Needs a yarn start end fixing device.

If the tension of the yarn is not maintained without holding and fixing the beginning of the yarn at the beginning of winding of each section, when the warp group is returned from the warping drum to the warp beam, the remaining 5- When rewinding the warp group for 6 turns, the tension of the yarn becomes insufficient and loosened, so that it is not possible to rewind the warp beam with even tension, and This makes it impossible to move the twill position, and in the case of strong twisted yarn, the winding itself is not possible. For example, the function as a partial warping machine is significantly impaired.

Therefore, for example, when winding of each section is started, the warping drum is automatically stopped at a predetermined position, and the steel tape for division is automatically sent out onto the warp group at the start of winding, and the warping is completed. Then, immediately before the winding operation to wind the yarn back from the warping drum to the warp beam, the warping drum is manually stopped at a predetermined position, the thin plate for press is attached to the steel tape for division, and the steel tape for division by the motor is used. By pulling back, the thin sheet for press is fixed to the warping drum with the yarn start end of each section sandwiched between the thin sheet for press and the warping drum, and the yarn start end of each section is fixed to the warping drum There is something to do.

However, in such a conventional yarn start end fixing device, it is extremely difficult to manually stop the warping drum at a predetermined position, and a thin sheet for pressing is formed on the yarn sheet at the beginning of winding of each section, and further on. In order to fully automate the partial warping machine, the winding operation to the warp beam becomes complicated, and the time required for the winding operation is greatly increased. It was a big restriction.

In addition, for example, there is a method and a device for fixing the starting end of the thread sheet using an adhesive tape (see Japanese Patent Application Laid-Open No. 2000-336644). Or the adhesive force of the adhesive tape is not sufficient. Les ,.

Therefore, the development of a yarn start end fixing device and a partial warping machine which has good operability and can be fully automated is expected.

With this configuration, as shown in FIG. 5, the angle adjusting plate 54 is set at a predetermined angle with respect to the base plate 53 (for example, the angle adjusting plate 54 substantially matches the inclination angle of the wavy projection 3 of the threading plate 2). (Fig. 5 (a)), and by extending the piston rod 63 of the air cylinder 62, the slide member 64 is extended horizontally (Fig. 5 (b)). The elevating plate 60 is lowered by extending the piston rod 57 of the air cylinder 56 (FIG. 5 (c)), and the elevating plate 6 is reduced by contracting the piston rod 57 of the air cylinder 56. raised to 0 [FIG 5 (d)], by Rukoto shrinks bis Tonroddo 6 3 of the air cylinder 6 2, it is possible to reverse the slide member 6 4 [Fig. 5 (e)] _c then The warp wound around the warping drum by the yarn start end fixing device having the above configuration. Operation for winding holding and fixing the thread starting end of the start will be described with reference to FIGS. 7 1 0.

FIG. 7 is an explanatory side view showing a state where the warp at the beginning of winding is wound on the warping drum. With the warp group A having been wound around the warping drum 12 wound, the rotation of the warping drum 12 is stopped at a predetermined position.

FIG. 8 is an explanatory side view showing a state where the thread pushing means is lowered and the warp is pushed into the thread hooking means. Lower the thread pushing means 20 and lower it until the thread pushing plates 24a and 24b come into contact with the rubber press plates 38a and 38c. The lowering of the thread pushing means 20 can be lowered vertically, but as described above, the descending angle of the thread pushing means 20 can be adjusted by the angle adjusting plate 54. For this reason, it is preferable to lower the thread hooking plates 2a and 2b at an angle along the inclination angle of the corrugated projections 3 of the thread hooking plates 2a and 2b. Due to the lowering of the thread pushing means 20, the warp group A at the beginning of winding comes into contact with the rubber holding plates 38a, 38c, and at the bottom of the thread introduction space 7 of the threading plates 2a, 2b. It is pushed down to.

FIG. 9 is an explanatory side view showing a state where the warp is hooked on the thread hooking means. When the thread pushing means 20 is raised, the warp group A released from the pushing force of the thread pushing plates 24a and 24b rises by the tension, and the thread catching portions 5 of the thread catching plates 2a and 2b 5 Multiplied by

By automatically performing the operation described in FIGS. 7 to 9 at the beginning of winding of each section, the warp at the beginning of winding of each section is entirely transferred to the threading portion 5 of the threading plates 2a and 2b. Will be hung. That is, the necessary warping length can be wound around the warping drum in a state where the warp at the beginning of winding of each section is all wound around the warping drum.

FIG. 10 is an explanatory side view showing a state where the warp is pressed and fixed by the yarn pressing and fixing means. When the warp is wound back onto the warp beam from the warping drum, the air cylinder 48 is operated several turns before the end of winding, for example, 5 to 6 turns before the remaining warping drum. When the middle plate 34 is raised, the warp group A at the beginning of winding wound on the threading portion 5 of the threading plates 2a and 2b is formed on both sides of the threading plates 2a and 2b. Are sandwiched between the flat rubbers 36a, 36b, 36c and pressed and fixed. As a result, the warp group A at the beginning of winding is held and fixed to the warping drum with a sufficient holding force with respect to the winding tension at the time of winding back onto the warp beam.

Next, the thread hooking plates of the thread hooking means are arranged in two rows in the longitudinal direction of the warping drum, and the thread hooking portion of one thread hooking plate and the thread hooking portion of the other thread hooking plate are staggered or zigzag. The operation and effect of arranging them in parallel with each other will be described. 3 Fig. 11 is a conceptual illustration of the effect of arranging two rows of threading plates, wherein (a) is before pushing in the warp and (b) is after pushing in the warp. When the warp in the range of the symbol P in FIG. 11 (a) is pushed down below the threading plates 2a and 2b by the thread pushing means, the warp protrusions 3a and 3b in the range of the symbol P Sliding down the yarn guides 4a, 4b, the yarn introduction path 6a,

After passing through 6b, it reaches the yarn introduction spaces 7a and 7b. Similarly, the warp yarns in the range of the symbol Q slide down the yarn guides 4c, 4b in the wavy projections 3c, 3b in the range of the symbol Q, and the yarn introduction paths 6c, 6b Pass through the yarn introduction space

7a, 7b.

Therefore, as shown in FIG. 11 (b), the warp in the range of the symbol P is pushed into the thread introduction space 7a in the threading plate 2a and the thread introduction space 7b in the threading plate 2b. Also, the warp in the range of the symbol Q is pushed into the yarn introduction space 7c of the threading plate 2a and the yarn introduction space 7b of the threading plate 2b.

Then, when the pressing force of the thread pushing means is released and the warp rises, the warp in the range of the symbol P is pushed rightward with respect to the warp in the thread introduction space 7a of the threading plate 2a. As a result, the warp in the thread introduction space 7b of the threading plate 2b can be classified into a thread that is hooked on the threading section 5a and a thread that comes off while the thread is threaded on the threading portion 5a. It is. Similarly, for the warp yarns in the range of the code Q, the warp yarns in the yarn introduction space 7 b in the yarn hooking plate 2 are pushed to the right side, so that the warp yarns 5 b On the other hand, the warp in the yarn introduction space 7c of the yarn hooking plate 2a is divided into a yarn hooked on the yarn hooking portion 5c and a yarn pulled out.

In this manner, the threading plates are arranged in two rows, and the threading portion of one threading plate and the threading portion of the other threading plate are arranged in a staggered or zigzag manner. By arranging the warps, the warp is hooked on at least one of the two hooking plates. Therefore, there is no possibility that a warp which is pulled out from any of the yarn hooking portions and is not hooked anywhere will occur.

The base plate 106 has a lower bearing 107 attached to the lower surface thereof, and is movable along a rail 108 laid over the entire length of the warping drum in the axial direction. Then, the screw shaft 1332 is rotated by the motor 128, whereby the base plate 106 moves itself in the longitudinal direction of the warping drum.

As described above, the cylinders 56, 62, the thread pushing plates 24a, 24b, and the like are attached to the moving column 50, and constitute the thread pushing means 20 (see FIG. 5).
