Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a yarn tension adjusting device in a warper for fibers.

[0002]

[Prior art]

 Generally, in the woven process, first, the warping operation is performed by winding a warp around a beam using a warping machine. For example, as shown in FIG. 5, the warp yarns 11 drawn out from a plurality of buns (rotating bodies around which the yarns 11 are wound) 9 mounted on a creel (not shown) that is a structural body are respectively After passing through various steps through a tension adjusting device 1 such as a compensator attached to a frame 10 near the pan 9, the beam (not shown) is taken up. Since the quality of the warp greatly affects the quality of the woven fabric, during the warping work, fluff, which causes weaving scratches, is removed, and partial loosening or tension of the yarn 11 is caused. The unwinding tension of the yarn 11 coming out of the pan 9 must be adjusted so as not to cause such problems. The adjustment of the unwinding tension of the yarn 11 is performed by the tension adjusting device 1 such as the compensator.

In the tension adjusting device 1, the tension is adjusted as follows. First, the thread 11 pulled out from the pan 9 passes through the insertion hole 3 of the disc 4, and the space between the upper dish body 7a and the lower dish body 7b of the first tensioner dish 7 is set between both dish bodies 7a. , 7b and passes. At this time, since the weight of the upper dish 7a is added to the thread, the thread passes while receiving the weight. This ensures that the thread is properly tensioned. When the yarn passes, the dish bodies 7a and 7b wrap around due to the passage friction of the yarn. The yarn that has passed between the dish bodies 7a and 7b also passes between the dish bodies 8a and 8b of the second tensor dish in the same manner, and tension is applied again. In this way, the yarn pulled out from the panel 9 is applied with proper tension by the first and second tensor dishes 7 and 8 to the beam without being loosened or excessively pulled. It is rolled up.

[0004]

[Problems to be solved by the device]

 However, in the tension adjustment by the tensor pans 7 and 8 as described above, if the warp speed is increased and the thread passing speed is increased, the panning speed of the dish 7a (8a) that moves around as the thread passes becomes faster, and gradually. There is a phenomenon in which the spinning speed becomes faster than the thread passing speed due to inertia. When such a phenomenon occurs, the yarn that comes out of the tensor dish 7, (8) sags. As a result, as shown in FIG. 6, the yarns 11 pulled out from the plurality of buns and arranged in parallel via the corresponding tensor dishes come into contact with each other, and fluffing and yarn breakage occur. Occurs. In particular, the thicker the yarn count, the greater the tendency, and there is a problem that warping cannot be performed at a warping speed of 100 m / min or more. In order to solve such a problem, it is necessary to increase the mutual distance between the yarns 11 arranged in parallel, but if this is done, a space is taken up and a wide space is required.

The present invention has been made in view of the above circumstances, and a tension that can wind a yarn drawn from a yarn source into a beam without requiring a large space and without causing yarn breakage. The purpose is to provide an adjusting device.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a tension adjusting device of the present invention is provided with a disk with a thread insertion hole which is arranged substantially at right angles to a thread path through which a thread drawn from a thread source passes, and a thread of the disk. A tensor dish is provided in which the thread inserted through the insertion hole is sandwiched between a pair of dish bodies. The tenser dish is provided in the middle of the thread path through which the thread that passes through the tenser dish passes, and the thread that passes through the thread path is rotated. A bobbin that is wound around the outer circumference of the tubular part and then travels to the yarn path on the downstream side, and a support that supports the bobbin with the axis of the rotating tubular part of the bobbin being at an acute angle to the yarn path are provided. Take the configuration.

[0007]

[Action]

 In the tension adjusting device of the present invention, a bobbin is arranged on the downstream side of the yarn path of the yarn passing through the tenser dish, and the axis of the rotating portion of the bobbin is set to an acute angle with respect to the yarn path by the support. There is. As a result, the thread that has passed through the tensor dish is not wound at a right angle on the axis of the rotating portion of the bobbin, but is obliquely wound around the rotating portion of the bobbin and then pulled out, as shown in FIG. Therefore, the force of the thread that rotates the bobbin is obliquely applied to the rotating part of the bobbin, which increases the frictional resistance between the rotating part of the bobbin and the shaft, which is the resistance of the rotating part of the bobbin. Becomes This prevents loosening of the yarns leaving the tensor dish, and prevents the yarns running in parallel from contacting each other. Further, by setting the axis of the rotating portion of the bobbin at an acute angle with respect to the yarn path, the locus of the yarn on the outer peripheral surface of the rotating cylindrical portion of the bobbin becomes spiral as shown in FIG. Since the winding end side is separated from the winding end side, the contact of the yarn on the outer periphery of the bobbin rotating portion is prevented, and the occurrence of yarn breakage or the like is prevented. By doing so, the yarn can be pulled out and properly wound around the beam without taking up a large space.

Next, this invention will be described in detail based on embodiments.

A pressing cylinder 14 is fitted on the vertical axis 5 (6), and its weight is applied to the upper plate 7a, (8a) of the plate. Reference numeral 15 is a retaining cylinder, which is fitted to the upper threaded portion of the vertical axis 5. Then, the pressing cylinders 14 having different weights are prepared, and by selectively using the pressing cylinders 14 according to the type of the thread 11, an appropriate tension is applied. The bobbin 21 is provided so as to form an acute angle (the angle formed by the bobbin and the bobbin 21 is acute) with respect to the yarn path of the yarn 11 that has passed through the tensor dishes 7, (8). In this case, the bobbin 21 and the yarn path of the yarn 11 that has passed through the tensor plates 7 and (8) are positioned on the same plane. The bobbin 21 will be described in more detail. As shown in FIG. 3, the bobbin 21 includes a rotary cylinder portion 22 and a shaft 23 thereof. Numerals 23a and 23b are stop rings for restricting the rotary cylinder portion 22 from moving in the axial direction. Reference numeral 11 is a thread, and point P is a turning point on the locus on the back side of the thread wound in a spiral shape. As shown in FIG. 1, one end of a shaft 23 of the pulley 22 is attached to a support body 24 made of a rod-shaped body, and a lower end portion of the support body 24 is rotatably supported by a receiver 25 in a circumferential direction. Has been received. More specifically, as shown in FIG. 4, engaging recesses 27 are formed at predetermined intervals on the outer periphery of the lower end of the support 24, and engaged protrusions 26 are formed on the receiving member 25 so as to project in the lateral direction. By engaging a predetermined engaging concave portion 27 of the engaging concave portion 27 with the engaged convex portion 26, the supporting body 24 is rotated by a predetermined angle with respect to the receiving member 25. It is designed to hold. As a result, the angle θ (see FIG. 3) formed by the yarn path and the axis of the bobbin 21 can be adjusted to a predetermined angle, and the tension of the yarn 11 can also be adjusted accordingly.

The angle θ of the bobbin 21 with respect to the yarn path of the pulley 22 is preferably 60 to 70 °, but is not limited to this. Further, the outer peripheral surface of the pulley 22 of the bobbin 21 is treated with hard chrome on the basis of titanium oxide or alumina so that the contact surface of the thread 11 has abrasion resistance, hardness, and slipperiness. It is suitable.
