Description

[Detailed description of the invention] The present invention relates to a creel equipped with a loading mechanism.

Conventionally, in order to manufacture belt-shaped textiles such as various safety belts,
Weaving can be carried out by winding the required number of warp threads around a beam, or by winding pre-warped threads onto a bobbin, placing this bobbin on a creel and sending the warp threads from the creel to the loom, or by weaving unwelded threads (filament yarns). The bobbin was wound onto a bobbin, and the bobbin was placed on a creel, from which the unfinished yarn was sent directly to the loom as warp yarn.

However, when weaving the warp yarns using the warp yarns, there are the following problems. In other words, when yarn is added, it is normally not done within the fabric manufacturer's office but is outsourced to an outside adding company, but it may also be necessary to change the degree of twist depending on the texture required for each individual fabric. regardless of,
It was inconvenient that the twist could not be changed at all during the weaving process. In addition, the same length of yarn is not always wound around each bobbin, and the yarn is unevenly wound, resulting in waste of yarn. Furthermore, the length of the yarn wound around the bobbin is usually shorter than that of the raw yarn, so it is a hassle to connect the yarn together during weaving, and the knotted part becomes a defective product and has to be discarded. I didn't get it. Furthermore, a rewinding process after joining and a warping process were necessary when winding the warp yarns around the beam.

On the other hand, when weaving rice yarn directly from a creel as a warp yarn, the large and pancage yarns are used as they are, so there is almost no need to connect the yarns together during weaving, and there is no need to rewind the yarns. The production efficiency is much better than the former case because there is no need for any process or warping process, and there is no need to send the raw yarn to an outside warping company for warping. However, the texture of the product is limited, and there are some quality issues such as weak stiffness and resistance to abrasion.Furthermore, threads tend to break during weaving and become fluffy. There was the hassle of having to restore the system to a normal state.

The present invention has been made in view of the above circumstances, and its object is to include a twisting mechanism that can simultaneously add twist to the rice yarn while feeding the rice yarn to the loom. An embodiment of the present invention providing a creel will be described below with reference to the drawings.

FIG. 1 is an overall view showing an example of a creel according to the present invention, in which reference numeral 1 indicates a creel main body, 2 a bobbin wound with rice yarn, 3 a loom, and 4 a winding roller of the loom 3.

A plurality of horizontal frames 5b are arranged at equal intervals in the vertical direction between the vertical frames 5a of the creel body 1 (in the drawing, there are 5 horizontal frames 5b).
A plurality of bobbins 2 are arranged in parallel on each horizontal frame 5b, and rice yarn A (filament yarn) is supplied from each bobbin 2 to the loom 3 as warp yarn. . Note that 50 in the figure is an intermediate vertical frame.

A motor 6 is mounted on one side of the creel body 1 (left side in Figure 1).
and a transmission 7 are arranged. A belt 8 is provided between the motor 6 and the transmission 7, as shown in FIGS. 2 and 3, so that the rotation of the motor 6 is transmitted to the transmission 7. The output shaft 9 of the transmission 7 has a Boo IJIO
(See Fig. 2), and the rotation of this boot I710 is performed via belts 11, 12, 13 and intermediate pulleys 14, 15° 16 provided at approximately mid-height positions on one side of the creel body 1. The power is transmitted to a pulley 18 (see FIG. 3) fixed to a spindle drive shaft 17 provided along each horizontal frame 5b. This causes each spindle drive shaft 17 to rotate in the same direction (see FIG. 3).

The spindle drive shaft 17 is provided with a bevel gear 20 (see FIG. 2) corresponding to each bobbin 2. This bevel gear 20 is connected to the spindle 2 as shown in FIG.
1 (on the left side in FIG. 4). The spindle 21 is connected to the spindle drive shaft 17 by a bearing portion 23 fixed to the horizontal frame 5b.
It is supported almost horizontally so as to be orthogonal to the A support tube 24 is externally fixed to the other end of the spindle 21 (left side in FIG. 4), and the above-mentioned bobbin 2 is attached to this support tube 24.
is supported, and the bobbin 2 is rotated by the rotational driving force transmitted from the spindle drive shaft 17. The rotational direction of the bobbin 2 is set to the direction in which the rice yarn A is unraveled (the opposite direction to the winding direction of the rice yarn). Further, the rotational speed of the bobbin 2 is determined by the above-mentioned transmission 7.
The faster the speed, the more power can be added, and the slower the speed, the less power can be added.

A flyer 26 is rotatably inserted between the bearing portion 23 of the spindle 21 and the support tube 24 . A loosening tension adjusting member 27 is provided between the flyer 26 and the bottom 24a of the support tube 24. This loosening tension adjustment member 27 has a knob at one end and is connected to the flyer 26.
A hollow threaded portion 2B is screwed into the threaded portion 2B, a brake shoe 29 is fitted into the threaded portion 28 so as to be movable in the axial direction and contacts the bottom portion 24a, and a brake shoe 29 provided within the threaded portion 28 is attached to the bottom portion. 24a side, and a spring 30 that biases the support tube 24a toward the bobbin 2 so that the flyer 26 rotates in the same direction with a predetermined spacing behind the bobbin 2.
Rotation is transmitted (wear transmission) from the flyer 26 to the flyer 26. This delay in the flyer 26 applies unraveling tension to the rice yarn A, preventing it from unraveling into pieces.

When the threaded part 28 is screwed in and the spring 30 is strongly compressed, the rice thread A is strongly pulled out (the unraveling tension becomes stronger).On the other hand, when the threaded part 28 is loosened and the spring 30 is weakly compressed, the rice thread A is pulled out (the unraveling tension becomes stronger). The yarn A is lightly pulled out (the unraveling tension becomes weaker).The degree of delay of the flyer 26 and the unraveling tension are determined by the rotational speed of the winding roller 40 of the loom 3 (winding speed), the rice yarn It can be varied depending on the thickness of thread A, the amount of winding, etc.

A support pipe 32 is provided at one end of the fryer 26 (upper side in FIG. 4) substantially parallel to the spindle 21. The support pipe 32 is provided with fixed Snell wires 3' 3 and 34 at one end position and approximately the middle position in the axial direction, and is movably equipped with a movable Snell wire 35 at the other end side in the axial direction. ing. This movable Snell wire 35 is adapted to adjust the dispersion of the loosening tension caused by the dispersion of the other end of the support pipe 32 (see Fig. 4) by means of a spring 36 provided within the support pipe 32. The yarn is pulled out from the bobbin 2, first passed through the fixed Snell wire 34 at the intermediate position, hooked onto the moving Snell wire 35, folded back by the moving Snell wire 35, passed through the fixed Snell wire 34 again, and hooked onto the fixed Snell wire 33 at one end position. As a result, the fixed Snell wire 33
From there, the yarn is guided to the machine 3 via a yarn guide on a creel and a yarn pulling alignment roller 40. Thereby, the yarn can be stably supplied to the loom 3. In addition, 41 in Figure 1
is a belt, and 42 is a lead.

Next, the operation of the above embodiment will be explained.

When the motor 6 is operated, its rotation is transmitted to the spindle 21 via the transmission 7, the intermediate boots IJ 14 , 15 , 16 and the spindle drive shaft 17, and the spindle 21 rotates the bobbin 2.

At this time, the flyer 26 is also rotated in the same direction as the bobbin 2 with a delay corresponding to the weaving speed (winding speed) through wear transmission between the brake shoe 29 and the bottom portion 24a. As a result, the rice yarn A is pulled out from each bobbin 2, and the flyer 26 applies a predetermined unraveling tension to the loom 3.
At this time, as the bobbin 2 rotates, the rice yarn A is twisted at the same time. Therefore, weaving is carried out by supplying the threads as warp threads to the loom 3, and the belt-like fabric after weaving is wound up by the winding roller 4.

In the above embodiment, a case is shown in which the loosening tension adjustment means 27 is provided to adjust the loosening tension using the repulsive force of the spring 300, but other means include a means using a magnet, a means using gravity, etc. Of course, it is also possible to set

As explained above, the creel of the present invention is equipped with a spindle that rotates the bobbin wound with rice yarn, so that the rice yarn is twisted at the same time as it is sent to the loom, and is therefore pre-processed. It eliminates the need to use twisted threads, eliminates the various inconveniences caused by using threaded threads, such as waste of thread and the trouble of connecting threads together during weaving, and eliminates the need for the rewinding process after threading. The warping process can be omitted and manufacturing efficiency can be improved. In addition, the spindle is equipped with a means (transmission) to adjust the rotational speed of the bobbin, making it easier to change the degree of twist during the weaving process, which was previously impossible, and improving the texture of the product. It is. Furthermore, the yarn can be stably fed to the loom using the flyer and the unwinding tension adjusting means (unwinding tension adjusting member).

In addition, since the yarn is fed to the loom after being twisted, it is possible to produce products with excellent texture, resistance to abrasion, and superior quality. Because it does not cause rough threads, it is possible to obtain products of higher quality.
