Abstract

A tension roller is eatablished, and contacts the warp. The warp is let out from the warp beam. A variation of the warp tension is transmitted to the speed-changer by the displacement of the tension roller. The velocity of the warp is controlled. When the loom is stopped, the transmission system of the tension-variation is stopped. Therefore, the loom is reversed, and a textile is returned to the designated position. When the transmission system of tension-variation is released, the warp beam is reversed, and the warp is wound to the indicated position of the speed-change ratio.

The present invention provides an inclined delivery device for controlling the inclined delivery speed of the inclined beam by transmitting a swing amount of the tension roller which contacts the inclined beam transmitted from the inclined beam and gives tension to the inclined beam to the transmission installed in the drive system of the inclined beam. It relates to a method of adjusting the inclination tension in frequent looms.

If a flaw occurs during weaving due to a misalignment in the prior art, the flaw generation part of the woven fabric is corrected without reversing the loom and weaved again from this part. Prior to this, only the inclined beam is inverted to rewind the relaxed slope to make the tension of the slope the same as when weaving.

However, in the past, this work was commissioned to the worker's sense or skill, and it was difficult to obtain a lot of trouble and time, as well as to obtain the same stiffness as when the loom was stopped.

For this reason, if the weaving resumes at a different state than when the light-tension is stopped, the output of the transmission is different from before the loom stops, and the delivery speed of the inclination is changed, so-called cutting and rear ends having different thicknesses of the woven fabric. There was a problem that occurred.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide an inclination tension adjustment method capable of accurately adjusting the inclination tension without requesting a feeling or skill of the operator.

Hereinafter, a first embodiment in which the present invention is embodied will be described with reference to FIGS.

) 1에는 경사비임축 2가 회동 가능하게 지지되고 이 경사비임축 2에는 경사비임 3이 착탈자재하게 착설되도록 되어 있다.First, the configuration of the inclined delivery device will be described.

1), the inclined beam shaft 2 is rotatably supported, and the inclined beam shaft 2 is installed with the inclined beam 3 detachably.

A transmission 4 is arranged on one side of the frame 1, and the input shaft 4a is provided with power from a drive shaft (not shown) via a timing belt 5 and on the rotational side of the transmission shaft 4b having the shift lever 6. Therefore, the rotational speed of the electric power is shifted and output to the output shaft 4c and transmitted to the inclined beam shaft 2 which is transmitted via the spur gear 7,8 bevel gear 9,10 10 11 and the upper wheel 12.

An electric or mechanical clutch (not shown) is provided between the warp beam shaft 2 and the output shaft 4c of the transmission 4 to disengage the clutch and to rotate the warp beam shaft 2 independently. Not shown) is installed.

In the rear upper position of the inclined beam 8, a frame roller 13 is rotatably installed in the frame 1 to guide the inclined Y which is sent out from the inclined beam 3.

The tension lever 14 is pivotally supported by the shaft 15 in the upper position of the inclined beam 3, and the tension roller 16 is pivotally installed at the end thereof, and the inclined beam is discharged upward from the inclined beam 3 via the rear roller 13. In addition to feeding Y to the heald frame (not shown) via 16, the tension lever 14 is oscillated about the side 15 in accordance with the tension variation of the inclination Y.

In the lower position of the tension lever 14 described above, the swing lever 17 is pivotably supported by the side 18 at one end thereof, and a connecting rod 19 is installed between the proximal end of the tension lever 14 and the distal end of the tension lever 14. At the same time, a spring 20 is provided between the connecting rod 19 and the tension lever 14 to absorb the momentary large tension or impact applied to the inclined Y during the beating or the maximum opening.

Between the proximal end of the swing lever 17 and the shift lever 6, the operating rod 22 is connected and the swing of the swing lever 17 is transmitted to the shift shaft 4b according to the tension change of the inclination Y. According to this, the rotational shaft 4b is rotated, and accordingly, the rotational speed of the inclined beam 3, which is changed by changing the transmission ratio of the transmission 4, is adapted to the tension variation of the inclined Y so that the optimum tension can be always given to the inclined Y. have. At the tip of the swing lever 17, an ordinary electromagnet 23 having a coil therein is fixed, and a suction plate made of magnetic material such as iron is arranged on the frame 1 so as to correspond to the moving area of the electromagnet 23 which is accompanied by the swing of the swing lever 17. 24 is fixed by bolt 25. In addition, the electromagnet 23 is in contact with the suction plate 24, which is normally electric, while the former magnet 23 is instantaneously given a great tension and impact on the inclined Y, such as during a beating light, or in relation to the stopping operation of the loom. The switch 29 shown in FIG. 3 is automatically closed, is connected to the power source E, is excited, and is made to adsorb | suck the adsorption tube 24. FIG.

In addition, the former magnet 23 is demagnetized by opening the separately installed switch 30 when the aforementioned level 29 is closed and excited.

This switch 30 is normally closed.

Nearly in the middle of the swing lever 17, a scale indicator rod 27 is installed at the bottom thereof, and as shown in FIG. 17 rotational positions, that is, the transmission ratio of the transmission 4, are indicated.

Thus, when the weave is straight, the inclined beam 3 is rotated from the drive shaft via the gear mechanism such as the transmission 4 and the spur gear 7, 8 so that the inclined Y is pulled.

As the warp Y is sent out, the diameter of the warp beam 3 decreases, and the amount of feed per unit rotational speed decreases, so that the warp Y tension gradually increases.

For this reason, the tension lever 14 is oscillated by the tension increase, the oscillation lever 17 oscillates via the connecting rod 19, and the shift 5-axis 4b is rotated via the operating rod 22 and the shift lever 6.

Accordingly, the transmission ratio of the transmission 4 is changed, and the rotational speed of the gradient beam 3 is corrected, so that the inclination Y is always sent at the same speed, that is, unchanged tension, so as to achieve homogeneous straightness.

In addition, the electromagnet 23 is normally in an inoperative state, at least when the loom is stopped, the switch 29 enters in connection with the stop operation, and the suction plate 24 is adsorbed so that the swing lever 17 becomes inoperative and the inclination tension of the loom is changed. Also, this is not transmitted to the shift lever 6, and the transmission ratio of the transmission 4 can maintain the state when the loom is stopped.

In addition, the operation of the electromagnet 23 may set the biting time or the maximum opening time during the weaving, if necessary. If a flaw occurs in the woven fabric due to misalignment during the weaving, the expectation is stopped by the miss detection device, and the switch 29 is automatically erected in connection with the stopping operation, causing the electromagnet 23 to be excited and the swing lever 17 to be unable to swing. It is braked and the transmission 4 is fixed so that the shifting operation is not performed.

Next, the weft is pulled up to the position of the flap of the woven fabric while the base is rotated by reverse rotation.

In this case, if the clutch interposed between the transmission 4 and the inclined beam 3 is dissociated, the inclined beam 3 can not be reversed but the inclination of the inclined beam can be reduced even if the expectation is reversed. In this way, when the defect is corrected, read the scale 28a indicated by the indicator 27a of the scale indicator rod 27 and check the transmission ratio of the transmission 4 indicating the inclination tension state at the time of loom stop.

Next, the switch 30 is opened to demagnetize the electromagnet 23, and the locks on the swing lever 17 and the transmission 4 are released. In this way, since the tension Y of the warp Y is reduced by the aforementioned flaw correction operation, the tension lever 14 and the swing lever 17 are both displaced and the shift lever 6 is displaced to a position different from when the loom is stopped.

Here, the clutch is interposed between the transmission 4 and the tilting beam shaft 2, and the handle is operated to reverse the rotation of only the tilting beam 3 to wind the tilting Y to increase the tension of the tilting lever, and the tension lever 14 and the swing lever 17 upward. Return and adjust the indicator 27a on the scale indicator rod 27 to the scale 28a identified above.

Therefore, since the tension of the inclination Y and the transmission ratio of the transmission 4 are set to the same state as when the loom is stopped, in this state, the switch 30 is closed to apply braking and the electric clutch between the inclination beam shaft 2 and the transmission is If the weaving is resumed after the connection, the weaving of the previously woven fabric and the unchanged homogeneous weaving can continue.

In this manner, the tensioning of the inclination can be performed very easily and accurately without depending on the feeling or skill of the operator.

Next, a second embodiment of the present invention will be described with reference to FIG. A tension lever 33 having a tension roller 31 and a tension lever 33 biased in the tensioning direction by the spring 32 and a swing lever 35 is supported on the coaxial 34, and between these levers 33-35 for absorbing the impact of beating start. Spring 36 is installed.

In the vicinity of the swing lever 35, the brake lever 37 is rotatably supported by the shaft 65, and the brake shoes 39 formed on the brake lever 37 foldably correspond to the brake surface 38 formed by the swing lever 35. The brake lever 37 is rotated in the separation direction by a release cam 42 arranged in correspondence with the cam follower 41 installed on the lower side of the brake surface 38, which is biased by the spring 40 and the brake shoes 39 are provided. It is supposed to be. The braking lever 37 is rotated in the braking direction when a large tension or impact is applied to the inclination Y such as during a beating light and when an expected stop is made.

Transmission 43 is composed as follows.

An eccentric wheel 45 is fixed to the input side 44 connected to the drive shaft, and a swivel wheel 47 with an operating rod 46 is slidably attached to the circumference of the eccentric side 45.

In the vicinity of the swing wheel 47, the L-shaped actuating lever 48 is pivotally supported by the shaft 49, and the tip of the actuating rod 46, which is electrically inserted into the long hole 50, which is disposed on one arm 48a. This position is fixed to fit.

Therefore, the oscillating wheel 47 reciprocates by the eccentric rotation of the eccentric wheel 45 according to the rotation of the input shaft 44, and the operating lever 48 reciprocates about the axis 49 via the operating rod 46.

The long hole 51 installed on the other arm 48b of the actuating lever 48 is fitted so that the end of the actuating lever 52 can be adjusted in position so as to reciprocate by the oscillation of the actuating lever 48.

At the other end of the drive lever 52, a feed tank (not shown) is provided so that the drive lever 52 reciprocates so as to engage and rotate with the gasket wheel (not shown), thereby inclining the beam 53 It is made to rotate in the direction of sending out this inclination.

In addition, an electrical or mechanical clutch not shown is interposed between the ratchet wheel and the support shaft of the warp beam 53. The warp beam 53 can be manually rotated by removing the clutch.

Therefore, by changing the distance between the long hole installation portion of the drive lever 52 and the shaft 49 of the actuating lever 48, the amount of rotation of the inclined beam 53 per unit revolution of the input shaft 44 is adjusted by changing the reciprocating stroke of the drive lever 52. There is a number.

The connecting rod 54 is connected between the fixed shaft of the driving lever 52 and the tip of the connecting lever 66 fixed to the swinging lever 35, and the driving lever 52 It is thus moved and the distance is changed between the drive lever 52 and the axis 49 of the actuating lever 48.

The connecting rod 54 extends upward and faces the scale 56a of the scale plate 56 fixed to the frame with its tip being guide 55. Therefore, the speed ratio can be confirmed by this scale 56a according to the up and down positions of the drive lever 52.

Next, a mechanism for releasing the fixed state of the tension lever 33 of the braking lever 37 described above will be described. The control lever 57 is supported by the shaft 58 on a part of the frame, and the foot shroud 59 is installed at the lower end of the control lever 57. The foot lever 59 is rotated by the foot lever 59 in the direction of brake release according to the operation of the control lever 57. It is supposed to be possible.

The operating lever 57 is biased in the direction in which the foot shroud 59 falls from the brake lever 37 by the spring 60. The operating lever 57 engages the pin 61 provided on the upper part with the regulating recess 63 of the regulating lever 62 and burns it at two positions, i.e., the brake release position and the brake allowable position by the action of the regulating recess 63 and the spring 64. It is supposed to be sexually positioned.

Therefore, when the tension Y increases due to the change in the diameter of the inclined beam 53 during the straight weaving, the roller 31 axis of the tension lever 33 becomes durable, so that the driving lever 52 actuates the shaft 49 of the operating lever 48 via the connecting lever 66 and the connecting rod 54. The shift ratio is changed so that the amount of reciprocation of the drive lever 52 is increased and the wind speed of the tilt beam 53 is increased so that the tilt tension is adjusted.

The change of the speed ratio at this time can be confirmed by the scale 56a and the guideline 55 of the scale plate 56. In the case of a woven flaw in the woven fabric, if the stop is stopped, the cam 42 stops at the position of FIG. 4, and the brake lever 37 brakes the swing lever 35 by the force of the spring 40 to fix the transmission 43 in an inoperative operation.

Next, reverse the expectations, correct the texture, and check the scale 56a indicated by Directive 55. The operating lever 57 is then rotated in the direction of releasing the brake to release the lock to the swing lever 35 and to allow the shifting operation of the transmission 43.

In this way, since the inclination tension is reduced by the defect fixing, the driving lever 52 moves the through hole 51 downward.

Thus, the clutch interposed between the ratchet wheel and the inclined beam 53 is peeled off, and the inclined beam 53 is reversed by manual rotation to rotate the inclined winding direction and the tension Y in accordance with the confirmed scale 56a is adjusted. At the same time, the drive lever 52 is moved upward by the tension lever 33, the swing lever 35, the connecting lever 66, and the connecting rod 54, so that the change ratio is made equal to the stop yarn of the loom.

Thereafter, the operating lever 57 may be returned to its original position, the braking lever 37 may be braked by the braking lever 37, and the clutch may be connected to resume straight weaving. Therefore, the same woven fabric as in the first embodiment described above can be obtained.

As exemplified in the above embodiments, the present invention is extremely easy and accurate to adjust the inclination of the inclination accompanying the inclination of the weaving by adjusting the inclination tension in accordance with the indication of the display means before resuming the weaving without depending on the operator's sense or skill. The outstanding effect which can be performed can be exhibited.
