KR790001942B1 - Warp tension control device on the circular loom - Google Patents

Abstract

The title device for manufg. a tubular fabric was described. The swing speed of a arm(10) and warp guide(11). was controlled by a pair of warp tension control devices(8) at the same speed of the running shuttle. The warp yarn of which tension was loosed by the swing arm was taken off from the bobbin and passed through the heald. The relaxation of warp tension was prevented by passing it through a warp supporting guide and a supporting plate on the heald.

)의 장력(張力)을 조절하는 장치에 관한 것이다.FIELD OF THE INVENTION The present invention relates to circular looms for weaving ordinary woven fabrics, and in particular for each warp yarn.

It relates to a device for adjusting the tension ().

)으로, 통상 직물을 제직하도록 된 원형직기가 일반적으로 사용되고 있다. 이 셔틀은 서로 간격을 두고 셔틀가이드에 우수개(偶數個)가 배치되고 종광은 셔틀가이드 외주(外周)를 따라 여러개 배열된다.As is well-known, a shuttle traveling along a circular shuttle guide and a heald which sequentially inclines the slope as the shuttle moves

In general, circular looms for weaving fabrics are commonly used. These shuttles are arranged in the shuttle guide at intervals from each other, and several healds are arranged along the outer circumference of the shuttle guide.

And the slope released from the multiple bobbins is led from the outside through the heald to the inside of the shuttle guide.

Each inclination always carries a resistance when it is released from each bobbin, and the magnitude of the resistance varies with the bobbin diameter or the wound state and always fluctuates. In the past, each inclination was led to a heald through an ordinary inclined guide, for example, a guide roller stiffened to rotate well, so that each inclination sent to the heald could be excessively taut due to the resistance when released.

In addition, the resistance when the bobbin is released is different and at that time, the tension of each inclination to the heald is also changed and changes from time to time. Because of this, we could not weave quality fabrics with this type of loom.

The present invention eliminates these conventional drawbacks, and it is possible to make the fabric of good quality by keeping the tension almost constant while alleviating over-tension of each inclination sent to the heald and preventing loosening.

According to this invention, an arm is arrange | positioned between a bobbin and a heald and it attaches so that it can oscillate. Then, the inclined guide is attached to the tip of the arm and the inclined guide is engaged between the bobbin and the heald. The arm swings actively by appropriate means.

Thus, each slope is actively released from each bobbin according to the arm swing.

As a result, the tension of each inclination sent to the heald is relaxed and the tensions are almost equal to each other.

Then, the inclined clamp guide is disposed between the inclined guide and the heald to release the inclined tip, and the clamping piece is brought into contact with the inclined clamp guide to sandwich each of the inclined clamps between the pinched clamp and the inclined clamp guide.

Therefore, each inclination is actively released from the bobbin. Even if the inclination between the bobbin and the inclined narrow guide is relaxed, the inclination sent to the heald is not relaxed, and the tension is almost always maintained.

An embodiment of the present invention will be described with reference to the drawings.

In the figure, (1) is a circular shuttle guide plate, (2) is a plurality of shuttle guide rods arranged in a circular shape, and (3) is a shuttle guide rail concentrically arranged inside the shuttle guide rod. (4) is an excellent shuttle and is supported by each shuttle guide, ie guide plate (1), guide rod (2), and guide rail (3) at regular intervals from each other. (5) shows healds arranged along the outer periphery of the shuttle guide.

(A) is the inclination of several strands, is unwound from each bobbin 6 arrange | positioned below, and is guided between the shuttle guide rails 3 through the heald 5 from the outside.

) 와 교직(交織)되어서 통상(筒狀) 직물(7)로 제직되어, 셔틀가이드레일(3) 사이로부터 윗쪽으로 보내진다.Although not shown, a mechanism for driving each shuttle 4 along each shuttle guide is provided, and a mechanism for vertically reciprocating the healds 5 alternately up and down is provided as the shuttle 4 travels. Therefore, the warp yarn A sent to each heald is sequentially opened on both sides of each shuttle 4 by the heald 5, and the weft yarn drawn out from the shuttle 4

) And weaving into a normal fabric (7), and is sent upward from between the shuttle guide rail (3).

(8) is the inclination tension adjusting mechanism of the present invention, the configuration thereof will be described with reference to Figure 2, (9) is a fixed shaft disposed between the bobbin (6) and heald (5), (10) is inclined It is an unwinding arm, and the upper end is rotatably attached to the fixed shaft 9.

11 is a guide roller for releasing the inclination, that is, the inclination guide, and rotates freely on the bottom of the arm (10).

The arm 10 is connected to the eccentric ring 19 via the link 20 as shown in FIG. 1, FIG. The eccentric wheel 19 is driven by a separate drive source at a speed proportional to the rotational speed of the mechanism for driving the shuttle. Thus, the arm 10 and the guide roller 11 move together with the eccentric wheel 19 and the link 20 to oscillate at a speed corresponding to the traveling speed of the shuttle. In addition, the eccentric wheel 19 may be connected to a mechanism for driving the shuttle, for example, via a gear or the like, and may be driven by moving in accordance with the movement of the main shaft 21.

The amplitude of the guide roller 11, that is, the angle at which the arm 10 swings, can be arbitrarily adjusted by changing the attachment position of the eccentric wheel 19 and the link 20 to the arm 10.

α represents the angle at which the arm 10 swings.

Reference numeral 12 denotes a guide roller for inclined pinching, that is, a pinching guide, and freely rests on the fixed shaft 10.

(13) is a clamping piece pressed against the outer circumferential surface of the clamping guide roller from above, and is fixed to the end of the arm 15 attached to the fixed shaft 14 freely.

Numeral 16 is an arm biasing spring and is connected to arm 15 via a link 17. Therefore, the arm 15 is urged clockwise around the fixed shaft 14 by the spring 16, and the clamping piece 13 is press-contacted to the outer peripheral surface of the guide roller 12 for inclined clamping by this biasing force. And (18) is a conventional guide roller disposed between the pinching guide roller and the heald.

Two sets of tension adjusting devices 8, which must be symmetrical to each other in one circular loom, may be provided at symmetrical positions with respect to the center line of the circular loom, and the number may be increased by a multiple of two sets as desired. .

線)으로 표시한 바와 같이 아암(15)을 스프링(16)의 부세력에 대항해서 들어올려서 용이하게 끼울 수가 있다.In the circular loom constructed as described above, the inclination A released from each bobbin 6 is engaged to the outer circumferential surface of each guide roller 11 and is sandwiched between the pinching guide roller 12 and the pinching piece 13. The sandwiching guide roller 12 and the sandwiching piece 13 are sandwiched by the dashed line in FIG.

As indicated by the line, the arm 15 can be easily fitted by lifting the arm 15 against the biasing force of the spring 16.

In this way, each inclination A sandwiched between the roller 12 and the pincer piece 13 is guided between the shuttle guide rails 3 through the heald and sent upward.

While the shuttle 4 is traveling and the heald 5 is actuated and the fabric 7 is being woven, the arm 10 oscillates actively and continuously with an amplitude of an angle α about the fixed axis 9. .

Therefore, each inclination engaged with the guide roller 11 is released from each bobbin 6 at the same time whenever the arm 10 swings.

The resistance when each inclination A is released from the bobbin depends on the diameter of each bobbin 6, the magnitude of the wound amount, and the wound state, but the difference in tension between each bobbin 6 and the guide roller 18 Previously, a U-shaped pin tensor was calibrated, and although not shown in the present embodiment, a single or plural U-shaped pin tensor for each inclination A between each bobbin 6 and the guide roller 11. Put it up. These pin tensors can compensate for large tension differences but cannot hope to compensate for tension differences in a range suitable for weaving.

The tension adjusting device 8 of the present invention swings the guide roller 11 according to the running speed of the shuttle, and selects the inclination A, which is approximately tension-adjusted with a pintensor, according to the weaving speed.

Therefore, the inclination between the guide roller 11 and the heald 5 is relaxed and the tension is almost equal to each other.

Then, when the arm 10 swings clockwise in FIG. 2 and each of the inclinations A is actively released, then when the arm 10 returns counterclockwise, each of the inclinations A is in the respective bobbin 6. There is a risk of loosening between the and guide roller 12.

However, since each inclination A is sandwiched between the pinching guide roller 12 and the pinching piece 13, even if it is loosened between the guide roller 12 and the bobbin 6, between the guide roller 12 and the heald 5 Does not loosen Therefore, the tension of each inclination A sent to the heald 5 is always kept substantially constant.

Therefore, high-quality fibers are woven into the weft yarns of each warp yarn A and each shuttle 4.

As evident in the above embodiment, the present invention is a guide attached to the end of the swinging arm, and actively inclines the inclination from each bobbin, so that the inclination of each incline to the heald can be alleviated excessively and each tension is almost equal to each other. I can keep it.

And since the inclination is sandwiched between the pinching guide and the pinching piece, each inclination sent to a heald can be prevented from loosening, and the tension can always be kept substantially constant.

Therefore, high quality fabrics can be made and the desired purpose can be achieved.
