摘要： PURPOSE:To obtain effective ejection of fluffy dust generated in a winder by connecting a suction pipe to a portion of a cover enclosing the portion where fluffy dust is apt to be generated so as to confine the fluffy dust in the cover and eject the same by suction. CONSTITUTION:A first cover 19 for enclosing a feeding bobbin 4 is composed of a cylindrical cover 21, a tapered cover 22 and a balloon breaker 6. A second cover for enclosing a tenser portion has four side faces and upper face closed and an opening 24 at the lower face, with an opening of a suction pipe 28 communicated at an upper portion of the back face 27. When suction through the suction pipe 28 reduces the pressure in the interior of the second cover 20, an air flow is generated in the first cover 19 by release and ballooning of the yarn. The air flow goes along the suction flow generated in the second cover 20 to be led into the second cover 20 from which the air along with fluffy dust is sucked into and ejected through the suction pipe 28. Thus, fluffy dust can be ejected, being remarkably prevented from scattering.

摘要： PURPOSE:To prevent the winding of the thread of a cut thread onto a drum by detecting the traverse cycle from the variation or the tension of a taken-up thread and suspending the feed of the thread when the number of revolution of the drum exceeds a prescribed quantity because of the abnormal traveling of the thread. CONSTITUTION:A traverse sensor 5 for detecting the tension of a thread A is installed in the vicinity of a drum 2, and a sensor 6 for applying a proper tension onto the thread A and stopping the feed of the thread A in the abnormal traveling is installed in the vicinity of a bobbin B, and further a drum sensor 8 for detecting the revolution of the drum 2 is installed in the vicinity of a driving power transmitting means 7. By such constitution, if a taking-up unit starts taking-up and the thread A executes the prescribed traverse along the guide groove 1 on the traversing drum 2, a traverse signal (a) due to the sensor 5 is supplied into a controller 10. When the thread A performs the abnormal traveling, the traverse signal (a) is not inputted, and a frictional plate is operated by the solenoid of the sensor 6, and the feed of the thread A is suspended.

摘要： PURPOSE:To prevent a yarn to be cut by tension when winding is completed, by providing a tension sensor for each winding unit to sense tension of a traveling yarn and also providing control means for controlling a winding speed of the yarn based on a signal from the sensing means. CONSTITUTION:A tension sensor 21 senses an increase in a releasing tension at the winding end of a spinning bobbin. When the tension exceeds a prescribed level, a control unit 16 applies a speed reduction command 17 to an inverter 15 to cause a rotational speed of a drum motor 12 to be reduced. More specifically, a speed of a yarn Y normally traveling at a prescribed speed is gradually reduced from the time when the tension sensor 21 produces an abnormal signal so that the yarn Y has a constant tension. With the arrangement, a yarn is prevented from being cut by an abrupt increase in tension.

摘要： PURPOSE:To make winding pressure for yarn in each layer sufficient and constant on a package as well as to prevent any winding looseness from occurring, by adding a state of tension to the yarn layer at the initial stage of yarn winding by a tenser in order to make up for a shortage of tension in the yarn at the time of rotation starting in the package. CONSTITUTION:At the time of starting the winding of yarn 3 on a package, a solenoid 26 of a tenser 20 is excited, attracting an arm 25, and a friction plate 22 is pressed to the friction plate 21 supported in a state of being clamped by a block 23, whereby sufficient tension is given to the yarn 3 lying between both these friction plates 21 and 22, and tension shortage at the initial stage is sufficiently compensated. And, when the package is reached to the specified speed, pressure force to the yarn 3 by these friction plates 21 and 22 is reduced, and tension of the yarn 3 is kept constant. Thus, on the package, winding pressure to the yarn at each layer becomes sufficient and constant so that winding looseness in the yarn is surely prevented from occurring.

摘要： PURPOSE:To make it possible to automatically introduce articles onto a path which requires the introduction of the articles, by integrally incorporating an article introducing member which is retractably projects onto an article conveying path, with a detecting member. CONSTITUTION:There is provided an introducing device 29 composed of a an article introducing member 29a which retractably projects onto an article conveying path 2 and integrally incorporated with a detecting member 29b for separatably touching the articles on an introducing conveyor path 4 to detect the presence of the article thereon, so that the introducing member 29a is shifted onto the conveying path 2 when the detecting member 29b is released from the article on the introducing path 4, thereby the article is introduced from the conveying path 2 onto the introducing path 4. With this very simple arrangement, articles on the conveyor path may be introduced in. Accordingly, in such a system that several introducing passages are branched off from a conveying path, desired articles may be automatically introduced onto a path which requires the introduction of articles, only by passing the articles on the conveying path.

摘要： PURPOSE:To attach wax uniformly to a yarn by providing solid wax of a tubular body in a yarn passage such that the yarn rewound to a package passel through the hollow portion of said sold wax in contact with the solid wax. CONSTITUTION:Wax 2 is supported by a support 1 so that a drawn-out yarn 3 is directed through the hollow portion of wax 2 to a take-up section. When the wax 2 is provided on a position were balloning is constitued by the centrifugal force action produced by drawing upward the yarn from a pirn yarn 8 with high speed, the ballooning is restricted by the inner peripheral surface of wax 2 so that the wax is attached to the peripheral surface of yarn by a frictional force at that time. Also, in a position where the ballooning is not produced, the wax 2 is rotsted about the axis. Thus, uniform wax can be applied around the yarn immediately after drawn out of the pirn yarn.

摘要： PURPOSE:To make an amount of cut yarn to be wound around a drum as smaller as possible, by dispoing a tension sensor in a yarn traveling passage between a bobbin on the yarn feed side and a package on the yarn winding side. CONSTITUTION:When traveling yarn is cut by high tension, high tension outside of a permissible range is applied to the yarn and a low tension outside of a permissible range is applied just after it has been cut. Therefore, when a tension sensor 7 senses the high tension, the low tension or both the high and low tension, a cutter 16 disposed in a yarn passage is actuated to cut the yarn. With the arrangement, when the yarn is cut at d drum, only a yarn of a length corresponding to a length between the cutter 16 and the drum 8 is wound around the drum 8 and no yarn is further taken out from a bobbin 2 even if the yarn would be wound around the drum. This is because that the yarn is forcibly cut at an intermediate position between the bobbin 2 and the extreme end of the yarn on a bobbin side.

摘要： PURPOSE:To prevent the cut of yarn and slaffing by installing a tension sensor for detecting the tension of a traveling system onto a winding unit and controlling the tension of the yarn on the basis of the variation signal of the tension of the yarn. CONSTITUTION:A yarn Y pulled out from a bobbin 1 is taken up onto a package 7 on a traverse drum 6 through a ballon breaker 2, tension device 3, yarn defect detecting head 4, and a tension sensor 5. The pressure due to the tension of the yarn is converted to a voltage in the tension sensor 5, and the increase and decrease of the tension is detected. The variation signal in increase and decrease is sent into a controller 9, and the tension of the yarn is varied by the control of the tension device 3. Therefore, the tension in the taking-up of the yarn onto the package 7 is kept constant, and cut of yarn and sluffing can be prevented.

摘要： PURPOSE:To restrain the occurrence of fluff in a high speed winder, by setting up a spiral guide member along a yarn running passage, and making the yarn run along the inside, in case of an automatic winder. CONSTITUTION:Yarn Y out of a spinning bobbin 1 is wound up on a package 6 to be rotated by a traverse drum 5 by way of a ballon breaker 2, a fluff restraint 3 and a slub catcher 4. This fluff restraint 3 is constituted of a spiral guide member 7, and its winding direction is releated to a twisting direction inherent in after-treated yarn, for example, it is an S twisted spiral for the sake of appearance to a Z weaving yarn XZ, while a yarn passing clearance 8 is almost circular in form at a plan view and its diameter (d) is a yarn diameter or so, and the yarn runs while contacting an inner wall as being bent. Therefore, fluff K1 is pressed toward an arrow 9 and thereby comes to be wound around an outer circumference of the yarn YZ in its inherent twisting direction. Thus, the fluff is restrainable.
