Description

Press and braking device for press roller of warper machine

The present invention uses a press roller equipped with an air flex brake with excellent pressurization and an excellent rapid braking force. By uniformly achieving the tension and winding arrangement of the yarn (tilt) is to be able to produce a good quality textile products.

In general, the yarn wound by the beam or drum of a warp machine (or beamer) will change the diameter according to the winding degree, and the tension and winding arrangement of the yarn will also change according to the change of the diameter. Since it directly affects the quality, there is a need to press the yarn wound with a beam or drum with a press roller to maintain a uniform tension and a uniform winding arrangement of the yarn.

Particularly, in the case of a matchmaking machine, the quality of the fiber product may be determined by the tension of the press roller, and when the tension is uneven, it may cause a slanted line. In addition, there is a problem in that the deformation of one side occurs even when combined with the beaming because the quality of the fiber product is greatly reduced and the defective rate is increased.

In addition, when the beam or the drum is suddenly braked, the press rollers that are slid therein must also be braked simultaneously to prevent changes in the physical properties of the yarn.

That is, even if the beam is braked by rapid braking, the inertia force exists on the press roller. Therefore, the beam and the press roller should be braked at the same time.

On the other hand, Figure 1 shows a press device 4 of a press roller 2 used in conventional warp machines, a pair of arms (8) on both shafts of the press roller (2) in contact with the beam (6) Fixed to the upper end of the arm (8) with a long rod (10) connected to each other so that the arm (8) is interlocked, and fixed to the weight 12 of 100kg or more in the center of the upper surface of the shaft (10) The center of gravity of the weight 12 is located behind the vertical center line 14 of the shaft 10 (in the opposite direction of the beam), and the disc brake 16 is installed in the lower part of the arm 8, and the arm In the configuration in which the rod 20 end of the air cylinder 18 is fixed to the upper end of the shaft 8 with the shaft pin 22, the weight 12 and the air cylinder 18 are located at the center of the shaft 10 instead of at both sides. Pressurizes the press roller 2 so that pressing force applied to both sides of the press roller 2 is not uniform, causing distortion of the press roller 2. Since the switch is left and right balance of the roller 2 is displaced is reduced, the quality of the textile product is a problem in that the shortening of apparatus life.

In addition, as the diameter of the yarn wound by the beam 6 or the drum increases, the press roller 2 moves backward, and the upper portion of the arm 8 and the weight 12 move forward in the direction of the beam 6 or the drum. The pressing force of the roller 2 is gradually reduced.

Therefore, the upper end of the arm 8 is pulled up by using the air cylinder 18 to increase the pressing force. However, since the pressure change occurs at the pulling point, there is a problem that uniform tension cannot be achieved.

Further, in the braking device 24 of the conventional press roller 2 used in the warp machine, the air cylinder 28 connected to the pneumatic device is fixed to the bearing 26 of the press roller 2, and the brake lining One side of the shaft 30 is installed on the bearing 26, the other side of the brake lining 30 is connected to the rod 32 and the link 34 of the air cylinder 28, the brake lining 30 is pressed It is a structure provided in the inner peripheral surface of the roller 2.

Therefore, when the rod 32 of the air cylinder 28 protrudes due to the sudden braking signal, the brake lining 30 is in close contact with the drum 36 of the press roller 2 and the braking is performed. When the braking signal is released, the spring is released. The brake lining 30 is spaced apart from the drum 36 of the press roller 2 by the restoring force of 38 to release the braking force.

In this case, since the air cylinder 28 is installed inside the drum 36 and only one brake lining 30 is installed at the bottom, the structure is relatively simple, but 180 ° rather than the entire area of the drum 36 (360 °). Since the braking is performed only by the front and rear friction surfaces, the braking force is weak and the braking is not performed well. The faster the beam rotation speed, the more serious this phenomenon becomes.

In addition, since one side of the brake lining 30 is coupled to the bearing 26 which is the shaft center, only a part of the brake lining 30 is easily worn, resulting in a high failure rate and a relatively short lifespan.

Therefore, the present invention achieves a uniform tension and arrangement of the yarn wound by the beam or drum of a regular aircraft using a press roller equipped with a pressurizing device and an air flex brake of a precise configuration. It aims to be able to produce a good quality textile products.

In order to achieve the above object, the support members are fixed to both sides of the fixed economy, and the L.M guides are installed parallel to the support members, and the L.M blocks are installed to slide on the upper surface of the L.M guides. The air cylinders are fixed to inner walls of both sides of the base, the L blocks are respectively fixed to the rod ends of the air cylinders, and the trays are fixed to the inner surfaces of the L blocks. Fix the bearing and install an air flex brake that can be braked at 360 ° on one or both sides of the press roller.

The air flex brake includes a cylindrical drum fixed to the shaft of the press roller, a cylindrical housing fixed to the bearing of the press roller by a shaft bearing, an expansion tube firmly fixed to the inner circumferential surface (inner wall) of the housing, and expansion during rapid braking. It consists of a solenoid valve and a pneumatic source that instantaneously blows compressed air into the tube and expands it, and a plurality of brake linings fixed to the inner circumferential surface of the expansion tube at regular intervals to face the drum.

In addition, the speed control valve is connected to the inlet / exhaust port of the air cylinder, and the precision regulator for regulating the discharge air pressure to the positive pressure is connected to the one speed control valve, the solenoid valve having a silencer, and the air pressure source are connected in sequence. Although it may vary depending on the type, etc., if the static regulator is applied before and after 1㎏ / ㎠ with the precision regulator, even if the winding diameter of the beam increases, the press roller moves backward to the set constant pressure of 1㎏ / ㎠, so that the constant tension and Make sure that the arrangement of the wound yarn is even.

3 is a planar configuration of the pressurizing device and the braking device of the press roller 40 of the present invention, wherein a pair of supporting members 46 are provided on both inner walls of the base 44 on which the beam (or drum) 42 is axially mounted. 48) (50) (52) are fixed, and the LM guides (54) (56) are fixed to the support members (46) (48) (50) (52) and installed in parallel with each other. By installing L. M blocks (LM blocks) 58 and 60 on the upper surfaces of the L. M guides 54 and 56, the L. M guides 54 and 56 may slide in the longitudinal direction of the L. M guides 54 and 56. Make sure

The rectangular tray 62 is fixed to the inner surfaces of the L.M blocks 58 and 60, and the air cylinders 64 and 66 are fixed to both inner walls of the base 44, and the air cylinder 64 ( The ends of the rods 68 and 70 of the 66 are fixed to one side of the L.M. blocks 58 and 60 by connecting members 71 and 73 so that both sides of the tray 62 can move forward or backward at the same time. do.

The support members 68 and 70 are fixed to both sides of the tray 62, and the bearings 72 and 74 of the press roller 40 are fixed to the support members 68 and 70 to provide air cylinders 64. The press roller 40 can move forward or backward in accordance with the operation state of 66 and the diameter of the thread.

Fig. 6 is a pneumatic circuit diagram of the pressurization device of the present invention, in which the speed control valves 76 and 78 are connected to the intake and exhaust ports of the air cylinders 64 and 66, respectively, and the discharge air pressure is supplied to one speed control valve 78. The precision regulator 80 regulates the positive pressure, the solenoid valve 84 having the silencer 82, and the air pressure source 86 are connected in turn, and the other speed control valve 76 is connected to the solenoid valve 84. As the diameter of the yarn wound by the beam 42 or the drum increases, the press roller 40 and the tray 62 which are retracted are subjected to the positive pressure discharge action of the air cylinders 64, 66 and the precision regulator 80. As a result, the tension and the arrangement of the yarns wound by the beam 42 or the drum are uniformly achieved, thereby making it possible to produce an excellent quality fiber product.

In addition, since the tray 62 supporting the press roller 40 is moved forward or backward at both sides by the L-M guides 54 and 56, the left and right balance of the press roller 40 is maintained. Therefore, the tension of the yarn to be wound becomes uniform.

In the present invention, the air flex brake 88 which is responsible for sudden braking of the press roller 40 is a braking device having excellent braking since it is braking at 360 ° as a kind of air brake.

7 and 8 are cross-sectional configuration diagrams of the air flex brake 88, a cylindrical drum 92 fitted and fixed to the shaft rod 90 of the press roller 40, and a bearing 72 of the press roller 40. As shown in FIG. The cylindrical housing 96 fixed to the shaft bearing 94 on the 74, the donut shaped expansion tube 98 fixed to the inner circumferential surface (inner wall) of the housing, and the compressed air by the expansion tube 98. A plurality of brake linings (102) installed so as to face the drum (92) fixedly fixed at regular intervals on the inner circumferential surface of the expansion tube (98) and the solenoid valve (100) and the air pressure source (86) which are blown and expanded in an instant. In general, since the expansion tube 98 maintains the contracted state, the brake lining 102 and the drum 92 are separated from each other, so that braking is released as shown in FIG. 7, but the solenoid valve 100 is opened by the rapid braking signal. Compressed air from the pneumatic source 86 When the expansion tube 98 is expanded and the brake lining 102 and the drum 92, which are separated from each other by the expansion pressure of the expansion tube 98, are subjected to strong braking as shown in FIG. .

Reference numeral 104 is a support disc, 106 is a pipe pipe, 108 is a thread, 110 is a bolt, 112 is a frame, 114 is a flange of a beam, 116 is a beam axis, (118) The thread guide roller, (120) is a diameter, (122) fixed piece.

In the present invention, it may vary depending on the denier or yarn type of the yarn 118, but applying a constant pressure of 1 kg / cm 2 before and after with a precision regulator, even if the winding diameter of the beam 42 increases, 1 kg of the press roller 40 is set. Since it reverses by the constant pressure of / cm <2>, even if a winding diameter becomes large, a constant tension is maintained and the arrangement | sequence of the yarn to be wound becomes uniform.

In addition, when the beam 42 is suddenly braked, the press roller 40 which is pressed against the beam 42 is also braked at the same time, thereby preventing a change in physical properties of the seal 118.

In addition, the press roller 40 is a high-speed forward at a high pressure at the time of the initial forward, it is preferable to advance at a low speed by the low pressure action of the precision regulator 80 when advanced about 2/3.

In operation according to the present invention, the press roller 40 is retracted by the action of the air cylinders 68 and 70 and then rotates forward by contact with the surface of the winding beam by advancing forward at the same time as the beam is mounted. The tension can be arbitrarily adjusted by the press action of the press roller 40, and the press roller 40 moves backward at a constant pressure in accordance with the size of the winding diameter.

In addition, since the braking speed can be increased by the air flex brake 88 mounted inside the press roller 40 when the machine is stopped, the beam 42 and the press roller 40 can be braked simultaneously. No friction occurs on the surface of 118), so that high quality textile products can be produced.

In addition, when the yarn is wound by the slide action of the L. M guide 54 and 56 and the L. M block 58 and 60, both sides of the press roller 40 are reversed at a uniform speed. Even if the size is different, the slide movement is smooth, and since there is no left and right deviation of the press roller 40, tension unbalance does not occur on the side of the beam and constant winding tension can be maintained.

In addition, the quality of the fiber product can be determined by the tension of the press roller 40, and if the tension is uneven, it may be a cause of slanted lines. Although there is a problem in that the quality of the product is deteriorated, in the present invention, a precision pressurizing device composed of L-M guide and L-M block and a press roller equipped with an air flex brake having excellent rapid braking force are provided. Since the tension and winding arrangement of the yarn wound with the drum or drum are uniformly achieved, these problems can be eliminated and a good quality textile product can be produced.

As described above, the present invention is wound by a beam or drum of a war racer using a press roller equipped with an air flex brake excellent in braking force and a precise pressurization device composed of an L-M guide and an L-M block. By uniformly achieving the tension and winding arrangement of the yarn, there is an effect of producing a good quality textile products.

In addition, although it may vary depending on the denier or yarn type of the yarn, if the static pressure is set before and after 1㎏ / ㎠ with the precision regulator, even if the winding diameter of the beam increases, the press roller is retracted to the constant pressure of 1㎏ / ㎠ which is set. Even if the winding diameter is large, a constant tension is maintained and the arrangement of the wound yarn is uniform.
