Description

Gradient feeding control device of the loom

The present invention relates to an inclined delivery control device of a loom. The present invention relates to a warp feeding control device for a loom that can eliminate unevenness.

Conventional Korean Patent Publication No. 90-4389 discloses a method for controlling the inclination tension of a loom. The control method winds the inclination of the transmission beam on a displaceable tension roller, and at the position of the tension roller, In the dispensing apparatus of the loom which balances the force in the displacement direction of the tension roller and rotates the drawing beam in the dispensing direction corresponding to the displacement of the tension roller, the displacement of the tension roller is synchronized with the rotation of the main shaft of the loom. Force, and by subtracting the actual tension of the warp by this force, the tension of the warp is set to the target value in one revolution of the loom. Problems, for example, smoothing the rotation of gears that exist when machining spur gears that form a reduction gear. There was a limit to the actual control of the inclination tension because the gap between the interlocked teeth and the teeth, that is, the failure of the inclination tension caused by the backlash, was not solved.

In addition, Korean Patent Publication No. 91-20230 discloses a tilt tension control device, which is a long-term stop mode control unit that generates a relaxation tension control signal corresponding to a target relaxation tension when a loom stop signal is generated, and a long-term stoppage. It includes a reduction switch as described above because it consists of a changeover switch for selecting the output side check of the control part of the mode, and an inclination tension mitigating means for setting the inclination tension as the target relaxation tension by inputting a relaxation tension control signal. As it did not solve the fundamental problem of the power transmission device, there was a limit in controlling the inclination tension substantially.

The inventors of the present invention have examined the problems of the prior art as a result, and as a result, the tension rollers which give tension to the discharging slope are supported in a displaceable state, and the electro-mechanical converting means is synchronized with the rotation of the loom. Even if the inclination tension and the force in the balance direction are applied, the tension change due to the change of the supply amount of the inclination wound on the transmission beam cannot be detected accurately, and it does not solve the fundamental problem of the power transmission device including the reduction gear device. It was found that it is not possible to control the tension control of one slope accurately, and came to complete the present invention.

Therefore, the purpose of the present invention is to install a second tension roller that moves by the inclination tension from the center point of the tension roller that gives tension to the inclination released from the delivery beam and to send the change in the supply amount of the inclination of the momentum of the second tension roller It is transmitted to the controller to immediately compensate for the slight deviation of the inclination tension during weaving, and the gear reduction gear of the power transmission device is also separated from the simple horizontal arrangement of the spur gear, and the gear arrangement is arranged in multiple stages. By fundamentally preventing the decay of the gradient tension caused by the backlash of the gear, and transmitting the increased rotational torque through the deceleration to the gearbox of the transmission beam, the low accuracy of the gradient tension control due to the structural problem of the power transmission device is improved. To provide an inclined delivery control device for looms All.

In the present invention, as illustrated in FIGS. 1 to 3, the tension roller 2 which gives tension to the inclination Y released into the inclined delivery beam 1 is piled up with the tension coil spring 3 and the tension roller 2. Controller (7) for controlling the operation of power transmission device (6) comprising a reduction gear device (5) for rotating the rotary shaft (4) of the inclined delivery beam (1) by detecting the displacement of The second tension roller 9 is supported on the upper part of the frame 8 on which the tension roller 2 is supported, and the frame 8 is provided on one side of the frame 8 in controlling the inclined delivery while transmitting to the frame 8. Proximity sensor 10 and a sensing distance adjusting member 11 corresponding to the rear of the sensor is attached, the sensing distance adjusting member 11 is fitted with a bolt 12 is fastened to the frame (8) A side plate 14 having a long hole 13 and a long hole 17 corresponding to the proximity sensor 10 and the tension proximity sensor 10a are provided. It is composed of a curved wing 18, the proximity sensor 10 is mounted on the sensor holder 19 is possible to adjust the gap with the wing 18, the sensor holder 19 and the proximity sensor 10 and The tension sensor 10a is mounted by keeping a constant distance horizontally, and the gap with the blade 18 can also be adjusted. The proximity sensor 10, when the blade 18 is detected in response to the woven tension change, increases the rotational speed of the sub-motor 19 to increase the rotational speed of the reduction gear device 5, accordingly the delivery speed To maintain the proper feeding field required for weaving in association with the inclined tension, and the long range sensor 10a is bolted to the long hole formed by the curved surface of the wing 18 corresponding thereto When the sensing surface of the sensor is exaggerated or stored due to a change in tension generated during weaving, when it is detected by the tension sensor 10a, it is judged as an abnormal tension phenomenon beyond the limit of tension required for weaving and immediately By stopping it, the tilt of the machine can be prevented.

The plurality of bolts 15 checked on the curved surface of the blade 18 is capable of appropriately varying the limit value setting of the tension because the mutual distance can be adjusted along the long hole. The blade 18 has a curved surface, and in order to adjust the distance d facing the fixed proximity sensor 10, the fastening positions of the bolts 12, 15 and the nuts 16 are varied. As achieved.

In the present invention, the gearbox gear 5 of the power transmission device 6 is largely divided into a spur gear reduction portion a and a majestic gear reduction portion b as well represented in FIGS. 2 and 3. The drive gear 21 fixed to the rotation shaft 20 of the servomotor 19 is engaged with the large gear 23 of the first intermediate gear 24 having the small gear 22 and the large gear 23. The small gear 22 of the first intermediate gear 24 is engaged with the second intermediate gear 25, and the dignity 27 on the rotation axis 26 of the second intermediate gear 25 is a dignity wheel. (28) is engaged, the rotary shaft (4) connected to the inclined delivery beam (1) is fixed to the key in the central inner cavity of the dignity wheel (28).

The present invention configured as described above has a controller (7) that senses this when the tension roller (2), which imparts tension to the inclination (Y) released from the inclined delivery beam (1), is displaced by tissue change during weaving. In addition to controlling the operating state of the power transmission device 6 through), as shown in the dashed-dotted line in FIG. 1, the amount of inclination (Y) wound on the inclined delivery beam (1) is changed. When a change such as relaxation is applied to the second tension roller 9 swinging around the tension roller 2 as a center point, the sensing distance supported by the frame 8 on which the second tension roller 9 is supported. Since the adjusting member 11 swings, the distance d set between the bolt 15 and the proximity sensor 10 of the sensing distance adjusting member 11 changes. At this time, when the proximity sensor 10 that detects the change in the interval d transmits the change to the controller 7, the controller 7 controls the rotation speed of the servo motor 19 of the power transmission device 6 so that the gradient tension is reduced. Will compensate for the deviation.

At this time, the rotational force of the servo motor 19 is transferred from the drive gear 21 fixed to the rotation shaft 20 to the second intermediate gear 25 through the large gear 23 and the small gear 22 of the first intermediate gear 24. And the dignity 27 on the same rotary shaft 26 as the second intermediate gear 25 rotates to rotate the dignified wheel 28 fixed to the rotary shaft 4 of the inclined delivery beam 1. Since it solves all the problems in power transmission for the backlash, which is present during the gear processing, the inclined transmission beam 1 can be precisely decelerated and rotated with an enhanced rotational torque.

Therefore, the present invention can satisfy the state of the power transmission condition known to be ideal for operating the loom ideally, that is, the inclined delivery beam 1 rotates 1 rotation when the rotation speed of the servo motor 19 is 6606. When the number of revolutions of 9) is 991, it is possible to satisfy all of the deceleration operation modes in which the rotation shaft 4 of the reduction gear device 5 rotates once. Such a reduction ratio may be varied in the design of the gear.

In addition, since the tension roller (2) is supported by the tension coil spring (3) and the shock absorber (3 '), the loom is placed in a stationary state for a long time, and is operated in a structure that greatly varies the tensile strength of the inclined slope. It is advantageous when weaving.

The present invention can compensate for the change in tension caused by the change in the tension of the warp and the amount of winding of the warp released from the discharge beam during normal weaving, and especially the mechanical on the power train. Since it solves the problem of power transfer due to backlash, which is a fundamental problem in gear machining, it has the advantage of being able to precisely adjust the inclination tension with high precision while responding to all the inclination tension changes occurring during weaving.
