Description

Description Motor-driven triaxial friction false twist device Technical field

The present invention relates to a triaxial multi-plate friction false twist device. More specifically, the present invention relates to a false twisting device used for a false twisting machine or a draw false twisting machine, etc., for twisting thermoplastic synthetic fibers such as polyester and polyamide. The present invention relates to a triaxial multi-plate friction false twist device of a type driven by a single motor provided in the device. Background art

A number of friction disks are attached to each spindle, and these spindles are arranged at the apexes of a triangle, and a triaxial multi-plate friction false twisting device is arranged so that the peripheral surface of the friction disk is spirally arranged. It is widely used as a twisting device for false twisting and drawing false twisting devices.

Conventionally, a tangential belt system has been known as such a triaxial multi-plate friction false twist device. That is, one belt is run along a machine of a fiber processing device such as a draw false twister or a false twister in which many such friction false twist devices are arranged, and a triaxial multi-plate friction temporary twist device is placed on the belt. The driving wheels of the twisting device are brought into pressure contact with each other, and drive is transmitted from the driving wheels to each spindle to rotate the three spindles in the same direction at the same rotational speed.

In the triaxial multi-plate friction false twist device, the spindle is fixed to the unit base as described above, and in this way, a large number of friction false twist devices are driven by one drive belt. In the tangential belt system, the belt is pressed against the drive wheels of the false twist device and the drive belt is run over a long distance, which is a source of noise. Also, in this tangential belt system, the friction false twist device is driven by frictional engagement between the belt and the drive wheel, so that the false twist devices are individually controlled so as to eliminate twist spots between many weights. It was very difficult. As a solution to such a problem, a single motor drive method, that is, a method in which one drive motor is installed in each false twisting device and the drive motor and the spindle are drive-coupled has been proposed. This connection method includes connecting the drive motor and the spindle by coupling, or attaching a timing pulley to each of the output shaft of the drive motor and one of the three spindles of the false twisting device, and setting the teeth between them. The connection is made via a belt attached. (See, for example, Japanese Patent Application Laid-Open No. Hei 4-209873).

In such a single-motor drive system, both pulleys are driven in order to reliably and without any maintenance between the drive-side timing pulley on the motor side and the driven-side timing pulley on the spindle side. It is necessary to keep the interval at a predetermined position and set the belt tension to a predetermined value.

In order to satisfy such demands, in a single motor drive type friction false twist device, the false twist device and each motor unit base can be removed from the spindle stand or frame of the textile processing machine during maintenance work or replacement of the friction disk. There is a need. However, such a detaching force has not always been easy in conventionally proposed devices.

On the other hand, Japanese Patent Publication No. 8-199585 discloses that a substrate of a false twisting device can be moved toward a drive motor fixedly mounted on a spindle holder of a textile machine, or can be swung. When the spindle is removed, the belt around the drive motor and the spindle is loosened by removing the spindle by moving the board of the false twisting device to the drive motor side. In this state, a device has been proposed in which a toothed belt stretched between a drive motor and a spindle is removed, and in this state, the false twisting device is taken out together with the substrate.

However, in such an apparatus, when removing the spindle, the belt wound between the drive motor and the spindle is loosened, so that the frictional force between the spindle and the drive belt every time the false twisting apparatus is mounted. The degree of adjustment must be adjusted on site, and adjusting the number of friction false twisting devices provided in the false twisting machine or the stretch false twisting machine is a very troublesome operation.

As a countermeasure, Patent No. 2 657 739 discloses a processing method including a friction disk assembly. It consists of a machine head and a motor block including a motor for driving the friction disc assembly. One shaft of the friction disc assembly is cantilevered on the machining machine head by bearings. The rotor of the electric motor is mounted on the shaft that protrudes from the head and protrudes from the processing machine head, and the rotor of the electric motor is driven by the electric motor to produce a calcined synthetic yarn that is fixed in the electric motor block. A false twist texturing apparatus has been proposed.

According to this proposed device, since the spindle is directly driven from the electric motor, the problem of adjusting the frictional engagement between the drive motor and the spindle is solved.

In the false twisting device disclosed in Japanese Patent No. 26595739, a tubular stator is mounted inside an electric motor block, and the tubular stator is Insert a columnar rotor into the hollow. However, accurate positioning of the rotor with respect to the stator is difficult because the stator is inside the motor block and cannot be seen from the outside.

Further, the false twist device disclosed in Japanese Patent No. 26575339 discloses a structure in which a rotor rotates inside a cylindrical stator, so that the diameter of the rotor is small and the rotor has a small diameter. Has a small moment of inertia. Due to the small moment of inertia, there is a problem in the stability of the rotation speed, and there is a risk of twisting.

Furthermore, the false twisting device disclosed in Japanese Patent No. 26575739 has a plurality of friction disks even if it is feasible to use only one spindle. This is not feasible for a three-axis friction false twist device with three spindles. The reason will be described below.

FIG. 1 and FIG. 2 of the above-mentioned Japanese Patent No. 26575339 disclose an embodiment of a triaxial multi-plate friction false twist apparatus. In the gazette, column 5, lines 4 to 8, `` 7 indicates a toothed belt wheel, and the shafts 8 and 9 are driven from there via a toothed belt meshing with the toothed belt wheel. The toothed belt is not shown in the force drawing that states: On the other hand, in the device shown in FIGS. 1 and 2, a projection is formed below the member supporting the three spindles 8 and 9, and this projection is formed on the block 6. The stator 4 and the rotor 3 of the electric motor are brought into a fixed position by engaging with the shoulders of the recesses formed. As is well known, in a triaxial multi-plate friction false twist device, three shafts are arranged at the apexes of a triangle at intervals larger than the friction disk attached to the spindle. When viewed in a plan view, the position where such shafts 8 and 9 are attached is located outside the peripheral portion of the concave portion formed in the motor block 6, and the shafts 8 and 9 in such a state are It is difficult to attach a toothed belt wheel to be engaged with the toothed belt at the end of the toothed belt even if one of ordinary skill in the art is used. It is difficult to drive with a toothed belt suitable for 7.

Incidentally, U.S. Pat.No. 4,895,533 corresponding to the above-mentioned Patent No. 2,657,539 includes, in FIG. 2, an arc-shaped projection projecting from the lower end of the motor guide 11. Member 20 is shown, and column 3, lines 45-50 of the description states: "A toothed wheel 7 is provided at the shaft position above the rotor, Endless belts 20 and 8 are driven by endless belts 20 which are wound around toothed wheels 7 and corresponding discs attached to shafts 8 and 9. Endless belts 20 It may be a toothed belt or a round or flat belt. "

As far as those skilled in the art are aware, there is no known endless belt as disclosed in FIG. 2 of U.S. Pat. No. 4,893,533, and such an endless belt is known. It is difficult to wrap between the buries and the toothed wheels 7 attached to the shafts 8 and 9 by belts.

Therefore, the device proposed in Japanese Patent No. 26595339 or U.S. Pat. No. 4,895,533 is still not suitable for a single-shaft type false twisting device. There is no feasibility in twisting devices.

The present invention can solve the problem that the three-axis friction false twist device associated with the three-axis friction false twist device disclosed in Japanese Patent Publication No. An object of the present invention is to provide an axis friction false twist device.

The present invention also provides a motor-driven triaxial shaft that facilitates positioning of a rotor and a stator of a false twisting device, and facilitates re-attachment after removal of the false twisting device for cleaning and maintenance or cleaning. The present invention provides a false twisting device.

In addition, according to the present invention, there is no variation in rotation during high-speed rotation, and twisting is less likely to occur, Another object of the present invention is to provide a motor-driven triaxial false-twisting device capable of twisting a thick denier yarn having a sufficiently large driving torque. Disclosure of the invention

In the present invention, three spindles each having a plurality of friction disks are rotatably supported on a spindle mount, and the spindle mount is detachably attached to the bracket, and the three spindles are mounted on the bracket. In a motor-driven triaxial false twisting apparatus in which a rotor of a drive motor is attached to one of the above and a stator of the drive motor is attached to the bracket, the drive motor is a radial gear gap type outer rotor. The above object is achieved by a motor-driven triaxial friction false twist device characterized by being a type brushless motor.

In the three-axis multi-plate friction false twist device according to the present invention, since each false twist device is driven by a single motor and does not use a tangential belt, the generation of noise can be greatly reduced. By changing the operating conditions of the individual motor for each weight, it is also possible to easily adjust the false twisting conditions for each individual weight.

According to the apparatus of the present invention, a radial gap type brushless rotor motor is used as the drive motor. In a brushless motor, the rotor can be a permanent magnet, so that no winding or the like is required as an outer rotor, and the arrangement of the windings and the like can be all integrated on the stator side. Therefore, according to the present invention, it is extremely excellent as a device which makes the aperture opening and closing possible.

In addition, in the present invention, the rotor is positioned outside, has a large diameter, and the inertia moment of the rotor can be increased by using a radial gear gap type rotor rotor type brushless motor, which is extremely advantageous for constant speed operation. . In addition, since a magnet (permanent magnet) is attached to a large-diameter rotor, the magnet can be made relatively large. For this reason, high efficiency and high torque are easily achieved, and this is effective as a false twisting device for thick denier yarn. In addition, the stator is located on the inner side, the winding resistance is reduced, the copper loss of the drive motor is reduced, and the drive motor power, and therefore the false twisting device, is easily improved in efficiency.

A spindle is rotatably supported on a spindle mount, and the spindle mount is detachably attached to a bracket. A rotor of a drive motor is attached to one of the three spindles, and the bracket is attached to the bracket. In a motor-driven triaxial friction false twisting apparatus to which a stator of the drive motor is attached, the drive motor is a radial gap type brushless motor with an opener port, and the brushless motor has an outer rotor having a bell shape.

A motor-driven triaxial friction member, which is opened and covered, and magnetically coupled between a circumferential portion of the rotor and a circumferential portion of the stator. By tio down false twisting device, to achieve the above object.

The brushless motor used in the present invention is a radial-gap-type brushless brushless motor. The shaft does not exist inside the brushless rotor as conventionally known as a brushless motor. In other words, the brush rotor of the brushless motor according to the present invention has a so-called bell shape and has a completely hollow inside, and the hollow portion covers the stator with a small gap.

With such a configuration, the autter rotor of the present invention does not need a bearing between the stator and the stator. In addition to the above-described effects, there is an effect that the autter rotor can be easily fixed.

Further, in the present invention, three spindles each having a plurality of friction disks are rotatably supported on a spindle mount, and the spindle mount is detachably attached to a bracket, and the three spindles are mounted on the bracket. In a motor driven three-axis friction false twist device in which a rotor of a drive motor is attached to one and a stator of the drive motor is attached to the bracket, the spindle mount and the bracket are The drive motor is provided with engagement portions that can be positioned relative to each other at a location away from the installation location of the rotor and the stator, and the drive motor is an outer rotor type brushless motor of a radial gap type. The above object is achieved by using a motor-driven triaxial friction false twist device.

In the invention disclosed in the above-mentioned Patent Publication No. 2,657,539, The rotor guide member supporting the handle and the electric motor block are engaged by the concave and convex engaging portions around the stator and the rotor. For this reason, the driving force of the three-axis friction type cannot be obtained. On the other hand, in the present invention, in consideration of the problem of the invention disclosed in Japanese Patent Publication No. An engagement part for positioning the engagement of the motor is provided at a position separated from a place where the rotor and the stator of the motor are installed, in an independent state different from the rotor and the stator of the motor.

By fixing the spindle mount to the bracket by this engaging part, the motor provided on the spindle mount is fixed to the fixed position with respect to the motor stator provided on the bracket. It is very easy to determine the position of both. In this state, the gap between the rotor and the stator of the rotor of the brushless rotor motor is also at a predetermined fixed position, and a desired magnetic coupling is formed between the two to achieve extremely high efficiency as a motor. can do.

Further, in the present invention, pulleys are attached to the ends of the three spindles, and the three spindles can be rotated in the same direction at the same speed by the drive belt wound around the pulleys. In the present invention, since the above-described configuration is employed, even when the burries are attached to the three spindle ends as described above, the configuration can be performed without any problem. That is, since the lower portion of the spindle mount is not used as an engagement portion with the bracket, this portion is sufficiently open, and a driving burry can be provided in this portion.

Further, as shown in the embodiment of the present invention, the three spindles are supported by the top plate on the side opposite to the end of the above-mentioned pulley, and the three spindles are respectively supported by the top plate and the spindle mount. It is preferable to be held and supported. In this way, the spindle is supported at both ends, so that the speed can be further increased.

Further, in the present invention, for the above-mentioned object, three spindles each having a plurality of friction disks are rotatably supported by a spindle mount. In a motor-driven triaxial friction false twisting apparatus in which a spindle mount is detachably mounted on a bracket in a lateral direction, a radial gear gap type rotor rotor brushless motor stay is mounted on the spindle mount and a rotor is mounted. An evening is rotatably supported around the stay, and is operatively connected to the outer rotor and one of the three spindles.

In the present invention, three spindles provided with a plurality of friction disks are rotatably supported on a spindle mount, and the spindle mount is detachably attached to the bracket in the lateral direction. Therefore, during the removal, the false twisting machine can be performed extremely easily without hitting or damaging other components provided in the drawing false twisting machine, and the main part of the false twisting device is removed upward. No problem.

Further, in the present invention, a radial gap type brushless brushless motor with a mouth opening is employed as a single drive motor of the false twisting device. As a result, the drive motor has high reliability and the drive motor does not need to be maintained or repaired on a false twister equipped with a false twisting device or a stretch false twister. The frame can be configured to be detachable in the horizontal direction with respect to the bracket. If maintenance or adjustment of the drive motor is necessary, perform maintenance, adjustment or replacement with the false twisting device removed from the false twisting machine and the draw false twisting machine. Mount the gantry sideways to the bracket.

Further, in the present invention, the stay of the radial gap type brush rotor motor is mounted on a spindle mount, and the rotor is rotatably supported around the stay. One of the spindles is operatively connected, and pulleys are attached to the lower ends of the three spindles, respectively, and the pulleys are connected by a drive belt, making the configuration compact. The spindle mount can be attached to and detached from the bracket laterally while the drive module is mounted.

According to the present invention, a radial gear gap type outer rotor is used as a drive motor. A brushless motor is used. In a brushless motor, the rotor can be made of a permanent magnet, so that no winding is required as an outer rotor, and the arrangement of the windings and the like can be integrated on the stator side.

In addition, in the present invention, the rotor is located outside, has a large diameter, and the inertia moment of the rotor can be increased by using a radial gear gap type rotor rotor type brushless motor, which is extremely advantageous for constant speed operation. . In addition, since a magnet (permanent magnet) is attached to a large-diameter rotor, the magnet can be made relatively large. For this reason, high efficiency and high torque are easily achieved, and this is effective as a false twisting device for thick denier yarn. In addition, the average value of one coil of the stator winding is shortened, copper loss is reduced, and the drive motor and, consequently, the false twist device are easily improved in efficiency.

In a more specific embodiment of the present invention, a step of a radial gap type rotor rotor type brushless motor is attached to a lower surface of the spindle mount.
