[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn feeder for conveying a cone package wound with a spun yarn to an automatic winder for rewinding.

[0002]

2. Description of the Related Art Generally, a large package is used as a yarn feeder, such as rewinding after a dyeing process, rewinding from cheese doffed in an open-end spinning machine, an air spinning machine, etc., into a cone, and a winding machine for winding into an arbitrary shape.・ To-corn type winders are known.

[0003] In a cone-to-corn type winder, the yarn supply is extremely large as compared with a spun tube yarn.
Automation of yarn feeding has been difficult for many years due to the large yarn outside diameter and heavy weight. However, the present applicant has proposed various means for automation (Japanese Patent Application Laid-Open No. 3-115070). .

In such a yarn feeding and processing apparatus, a cone package is inserted into a peg of a tray, and is conveyed to a yarn end take-out device for smoothly passing the yarn end by an automatic winder. The yarn is sucked with a suction mouse, the end of the yarn is searched for, and the yarn is held at the tip of the peg.

[0005]

In order to carry out the above-mentioned pouring process, when the cone package is inserted into a tray and conveyed to a pouring device by a conveyor, the yarn at the yarn end portion wound around the outer periphery of the package is conveyed during the conveying process. Looseness may cause the yarn to fray around the package.

As described above, when the yarn end portion leaned on the outer periphery of the package is conveyed by a belt conveyor such as a flat belt, a twist belt, and a round belt, the yarn end is caught between the conveyor and the tray. There is a case where the yarn end being conveyed in the step is conveyed to the exit device in a state where the yarn end is stepped on. Even if such a package is conveyed to an ejection device and the periphery of the package is suctioned by a suction mouse, the suction force of the suction mouse cannot suck the yarn end between the conveyor and the tray because the package is large and heavy. And therefore could not be tapped.

Therefore, according to the present invention, even if the yarn end of the package is sandwiched between the tray for inserting and conveying the package and the conveyor, the feeding of the yarn end can be surely performed. An object of the present invention is to provide a yarn conveying device.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a tray rotating device for rotating a tray in a direction in which a yarn of a package is wound, and a yarn pick-up projecting laterally between a lower surface of the package and an upper surface of the tray. Guide and the package of
By providing a feeding path to a feeding device that performs a yarn end feeding process, a feeding device for yarn supply is configured.
Thus, even when the yarn end of the package is sandwiched between the tray for inserting and transporting the package and the conveyor, it is possible to reliably perform the thread end processing.

[0009]

According to the present invention, as described above, the package inserted into the tray and transported by the conveyor is:
A yarn pick-up guide projecting from the side enters the space between the lower surface of the package and the upper surface of the tray in front of the feeding path of the picking device for performing the picking process of the yarn end. If the yarn end of the package is caught between the tray and the conveyor, the yarn pick-up guide enters the yarn end portion from the center of the package and pulls it out.
At this time, since the tray is rotated in the direction of winding the yarn of the package, the yarn is wound in while the yarn end is regulated by the yarn pick-up guide, and the yarn end sandwiched between the tray and the conveyor is pulled out and lightly wrapped around the package. It is wound. In this manner, the package whose yarn end is lightly wound around the package is conveyed to a yarn end discharging device by a conveyor, and the discharging operation is performed.

[0010]

An embodiment of the present invention will be described with reference to the drawings. Figure
As shown in FIG. 1 , a plurality of winding units 2 and a yarn feeder 1
Are connected by an empty tray conveyor 3 and an actual tray conveyor 4. The yarn feeder 1 is provided with an annular conveyor 5, and the annular conveyor 5 is provided with an empty bobbin extracting device 6, a yarn feeder 7, and a tapping device 8. Further, the yarn supply device 7 can be divided into a yarn supply insertion device 9 and a yarn supply storage device 10.

The beg tray on which the empty bobbin discharged from the winding unit 2 is placed is conveyed on the empty tray conveyor 3 and the empty bobbin is removed at the point P on the annular conveyor 5, and the empty tray is moved to the point Q. The yarn is supplied and supplied by the yarn supply device 7, and at a point S, the yarn is fed by the reeling device 8 and then conveyed to the winding unit 2 by the actual tray conveyor 4.

As shown in FIG . 2 , a tray 14 for inserting and supporting a peg 13 into a center hole of a hollow bobbin 12 of a large-diameter cone package 11 is conveyed to a winding unit 2 by a belt conveyor 5. A conveyance path for conveying the cone package 11 to the winding unit 2 by the belt conveyor 5 includes:
The apparatus includes a tapping device 8 for tapping a yarn end of a package. A tray stopper 18 protruding from a side of the belt conveyor 5 by a cylinder 17 is provided on a transport path leading to the outlet device 8. The tray stopper 18 has an arm 21 supported by a pin 19 at the tip of a rod 20 that can be protruded by the cylinder 17, and guide rollers 22 provided at both ends of the arm 21 move the tray 14 transported by the belt conveyor 5. When it is conveyed to the position of the tray stopper 18, it is projected by the operation of the cylinder 17, and the guide roller 22 is brought into contact with the side of the tray 14 and pressed.

On the side of the belt conveyor 5 opposite to the tray stopper 18, a tray rotating roller 23 is provided. When the tray stopper 18 pushes the tray 14, the opposite side of the tray 14 contacts the tray rotating roller 23. Pressed. The tray rotation roller 23 is driven by a motor 24, and as described above, the tray 14
When the motor 24 is driven while being pressed against the tray rotation roller 23 by the guide roller 22, the tray rotation roller 23 moves the tray 1 in the winding direction of the yarn of the package 11.
4 is rotated counterclockwise in FIG.

The substrate 25 supporting the motor 24 includes:
The base of a thread pick-up guide 26 having a fan-shaped tip is fixed, and a thread pick-up portion 27 at the tip of the thread pick-up guide 26 extends between the lower end surface 28 of the package 11 and the upper surface 29 of the tray 14. A yarn guide portion 32 is formed from the distal end to the base portion 31, and the yarn pickup portion 27 is formed in a fan shape by the yarn guide portions 32 on both sides of the yarn pickup portion 27.

In the above-mentioned apparatus, when the tray 14 on which the package 11 is inserted is placed on the belt conveyor 5 and the package is conveyed, the package is transferred to a tapping station provided with a tapping device 8 for tapping a yarn end. After being transported and reaching the tray stopper 18, the cylinder 1
7 operates to push out the tray stopper 18 and press the guide roller 22 provided at the tip of the arm 21 against the side surface of the tray 14. At this time, if there is a contact error between the two guide rollers 22 and the side surface of the tray 14, it swings around the arm 21 and the pin 19, absorbs this error, and the two guide rollers 22 are evenly placed on the side surface of the tray 14. Press.

When the tray 14 is pressed by the tray stopper 18, the other side of the tray 14 comes into contact with the tray rotating roller 23, and the motor 24 is driven in this state. Thereby, the tray rotation roller 23 rotates counterclockwise in FIG. 1, and rotates the package 11 in the winding direction of the yarn.

At this time, the yarn end 30 of the package 11 conveyed by the tray 14 hangs down, is sandwiched between the lower surface of the tray 14 and the upper surface of the belt conveyor 5, and the yarn end is trampled by the tray 14. When the package 11 is being conveyed by the belt conveyor 5, the package 11 rotates in the direction in which the yarn is wound, so that the hanging and slack yarn end is wound around the package. At this time, the yarn end 30 is hooked on the yarn guide portion 32 formed on the side edge of the fan-shaped yarn pickup guide 27, and the rotational movement of the yarn end is regulated at this position, and the yarn traversed on the tray 14. The end is wound around the outer periphery of the package, and finally, the yarn end is lightly wound around the outer periphery of the package.

As described above, in the package in which the yarn end is lightly wound around the outer periphery of the package, when the suction mouth sucks close to the outer peripheral surface of the package for the opening process of the yarn end, the yarn end is surely sucked. It is sucked by the mouse, and thereafter performs a predetermined tapping process. When the yarn end is sucked by the suction mouth, the package is rotated in the direction opposite to the winding direction of the yarn, and the yarn end is extended.

At the position where the yarn end is picked up by the yarn pick-up guide 27 as described above and the yarn end is wound around the outer periphery of the package, the motor 24 is used to move the suction mouth close to the outer periphery of the package.
Is rotated in the opposite direction to rotate the package in the direction opposite to the direction in which the yarn is wound.

In the above-described embodiment, such a yarn feeding device may be provided at any position between the yarn feeding station Q and the outlet station S. Also,
Although the belt conveyor 5 uses a flat belt, the same operation as described above is performed when the yarn supply is conveyed by a belt conveyor using a twist belt or a round belt.
