Description

[Detailed description of the device]

The present invention provides a hollow spindle, which rotates at high speed, on the yarn feeding side for constant-speed winding in all modes of a winder, and particularly in a pan winder, and feeds through the hollow spindle. The present invention relates to a control technique in which a yarn 1 and a bobbin or bun feed yarn 2 on a spindle are compound-twisted, the number of twists is kept constant, and the yarn is wound into a predetermined shape.

[0002]

[Prior art]

 Conventionally, when making composite twisted yarns, in a plying machine or a special dedicated machine for complex plying yarns, the compounding yarns are directly combined and twisted, and most of the winding is done in an aluminum cylinder. It was

[0003] Therefore, the winding speed of the yarn to be the composite twisted yarn is at most several meters to several tens of meters, and the yarn speed is very slow and inefficient. In addition, the installation of the sensor for detecting the thread breakage has a drawback in that it is also very difficult to install due to the small pitch between the weights and the structural problem of the machine itself.

[0004]

[Problems to be solved by the device]

 The efficiency of the above-mentioned composite twisting machine must be increased, and the detection speed at the time of yarn breakage must be increased so that the single yarn is not wound.

Therefore, an object of the present invention is to solve the above-mentioned problems and to use a highly reliable sensor which has high efficiency and completely eliminates winding of a single yarn. If a yarn breakage occurs in the yarn supply, the cutter will immediately cut the yarn.

In order to achieve the above object, in the winder of the present invention, in particular, for uniform speed winding of all modes of a pan winder, a hollow spindle rotating at a high speed is used on the yarn feeding side, A yarn 1 that is rotated a fixed amount and passes through the spindle from the bottom to the top, and a yarn 2 that is fed from a bobbin or pan that rotates at a high speed on the spindle are compound-twisted at a large circular guide and passed through a traverse guide. Then, it is wound into a predetermined shape on the winding pan. Tensors 1 and 2, a yarn traveling sensor, a balloon sensor and a cutter are provided on the way, and if a yarn break occurs in one of the yarn feeds, the cutter immediately cuts the yarn. Further, the number of rotations of the spindle is output by the spindle motor inverter at the frequency set by the spindle motor speed setting device, so that the number of twists of the composite twisted yarn can be freely selected.

[0007]

[Action]

 In a winder, especially in a pan winder, it is possible to realize a composite twisted yarn with any number of twists for uniform speed winding in all modes, so that it is highly efficient, or even if it has a predetermined shape with almost no single yarn winding. It is possible to wind up, and it is possible to make high value-added products in the twisting machine in the next process. In addition, the bobbin on the spindle can be made into a pan, and the winding side can be selected, so that it can be used for both a bobbin twisting machine and a parn twisting machine.

【Example】

 Although there are FIGS. 1 and 2, an embodiment of the school plan will be described mainly with reference to FIG. FIG. 1 shows the structure of a composite twisting machine in a winder of the present invention. In a winder, especially in a pan winder, a yarn speed detector 9 detects a winding speed from a signal from a roller 10 which is rotated by a rubbing force of the yarn, and the winding speed is fed back for warp winding and feeling. Even in winding and wandering winding, uniform yarn speed winding is realized. The feedback yarn has 14 FV signal exchangers and 8 take-up speed command controller. This command voltage P2 controls the take-up motor inverter 7 to enable the take-up motor 6 You are in variable speed operation.

On the other hand, 46 yarn feeds 1 from 1 yarn feed pan 1 are given appropriate tension by 20 tensers 1 and then pass through 21 yarn running sensors, whereby 1 yarn feed pan Detects thread breakage of 1. Then, passing through the roller guides 1 to 4 of 22 to 25, passing through the hollow part in the spindle of 39 which rotates at high speed from the bottom to the top, on the spindle, 41 of 41 from the yarn supplying bobbin rotating at high speed is passed. The yarn feeder 2 and the yarn feeder 2 are combined and twisted at 42 large circular guides.

Since the center of the large-sized circular guide 42 is slightly displaced from the optical axis of the balloon sensor 43, the yarn breakage of the composite twisted yarn completion yarn 47 is not detected, and the yarn supply 2 41 When the balloon is detected, it outputs the thread breakage force when the balloon is stopped, turning off the operation relay in the spindle motor operation-stop box of 36, and at the same time turning on the relay for dynamic braking, The spindle motor is braked and stopped quickly to prevent the thread from breaking. The dynamic brake is released by the timer after a suitable amount of time and the spindle motor is freed. At the same time, the cutter of 45 cuts the single yarn and holds the yarn end by the stopper. When the yarn traveling sensor 21 detects the yarn breakage of the yarn feeder 1 46, it also moves in the same manner to stop the spindle motor. The spindle rotates via 27 spindle drive belts.

Although not shown in the figure, since the run-stop box is used for the winding motor 6 as well, the output of the yarn traveling sensor 21 and the balloon sensor 43 43 is also used for driving the winding motor. When the relay is turned off, the free run stops and the thread is less damaged. If the run-stop box and the spindle motor run-stop box of 36 can be bidirectionally controlled, the spindle motor can automatically operate in conjunction with each other when the winding motor is operated.

Since the winding motor 6 can wind at a constant yarn speed in any mode, if the spindle motor speed setter 34 sets an appropriate speed, the 32 spindle motor inverters can respond to it. By outputting the frequency, the spindle motor of 30 is rotated at a constant speed of an appropriate value, and the spindle of 39 is also rotated at a constant rate. Therefore, the composite twisted yarn of 47 is wound into a predetermined shape with a constant number of twists. To be This twist number can be freely determined by the rotation speed of the take-up motor of 6 and the rotation number of the spindle of 39, and can be varied from a soft twist to a medium twist.

In order to make a reciprocating constant velocity linear motion of the traverse bar 5 by using the AC servo motor, the output P2 of the winding speed command controller 8 is used for the speed command of the AC servo amplifier. Since it is possible to realize a compound twisting machine with a constant yarn speed and a constant yarn pitch, it is possible to produce yarn with a very high added value.

[0014]

[Effect of device]

 As described above, according to the present invention, not only the efficiency can be improved as compared with the conventional ply-twisting machine or the special twisting machine for composite yarns, but also 40 yarn-feed bobbins or pans can be installed on 39 spindles. Since it is good, the winding side can also be selected, so it is a major feature that it can be used for a twisting machine for bobbins and also for a double twister using a pan. Further, by using highly reliable ones as the yarn traveling sensor 21 and the balloon sensor 43, it is possible to almost completely prevent the single yarn winding. It is also an advantage that the number of twists of the 47 composite twisted yarns and the winding speed thereof can be freely selected in a considerably wide range.

Claims (1)

[Scope of utility model registration request] 1. A winder, in particular, a pan winder, regardless of warp winding, feeling winding, or wandering winding, detects a winding speed of a yarn by a signal from a roller which is rotated by a frictional force of the yarn. With a pan winder that winds the yarn at a constant speed according to the signal, the yarn fed by the pan is passed through the tensor and the yarn traveling sensor and then passed through the hollow spindle that rotates at high speed from bottom to top. , The yarn from the high-speed rotating yarn feeding bobbin or yarn feeding pan, that is, the yarn feeding 2, is entangled, passes through the large circular guide, and then enters the tenser 2 and passes through the cutter, The composite twisted yarn is wound into a predetermined shape on the winding pan through the traverse guide that passes through the detector and traverses to the left and right. Therefore, if the number of rotations of the spindle is made constant, the number of twists of the yarn becomes constant, and in order to detect the yarn breakage, a yarn traveling sensor is attached to the yarn supply 1,
At the large circular guide, use a balloon sensor and slightly shift the optical axis from the center of the large circular guide.
