BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic switching winding device for winding intertwined yarn, in which a turret-type automatic switching winding device winds a twisted yarn that has been intertwined with gas.

0002

[Prior Art] In recent years, high-speed spinning methods such as high-speed spinning methods and direct spinning/drawing methods have been widely adopted in the production of synthetic fibers from the viewpoints of speeding up, automation, labor saving, etc. has come to be widely used not only for the weft of textiles but also for the warp of textiles and knitted fabrics.

[0003] In such a high-speed silk reeling method, usually,
A turret-type automatic switching winding device is used, and in order to improve the processability of the yarn, it is necessary to intertwine the yarn before winding. The number of entanglements imparted to the yarn needs to be changed depending on the use of the yarn.

[0004] In order to change the number of entanglements imparted to the yarn, a method generally employed is to change the pressure of gas supplied to the gas entanglement nozzle. In other words, the primary side (source pressure) and the secondary side (
A pressure reducing valve is installed between the nozzle (entangled nozzle) and the opening degree of the pressure reducing valve is adjusted.

[0005] In the turret type automatic switching winding device,
When trying to change the number of interlaces of yarn wound before and after the turret, for example, when changing from a yarn with a low number of interlaces to a yarn with a high number of interlaces, after winding the yarn with a low number of interlaces, It is necessary to perform automatic switching, adjust the opening degree of the pressure reducing valve to set a gas pressure corresponding to a high number of entanglements, perform automatic switching again, and wind up a yarn with a high number of entanglements.

[0006] In other words, a yarn in which a part with a high number of entanglements is continuous with a part with a low number of entanglements that occurs in the middle of switching from a yarn with a low number of entanglements to a yarn with a high number of entanglements cannot be made into a product.
It had to be disposed of as waste thread.

[0007]

[Problems to be Solved by the Invention] The present invention eliminates the generation of waste yarn due to the change in the number of interlaces when changing the number of interlaces of yarn to be wound before and after the turret in a turret type automatic switching winding device. An object of the present invention is to provide an automatic switching winding device for entangled yarn.

[0008]

[Means for Solving the Problems] The present invention solves the above-mentioned problems, and its gist is to automatically wind the interlaced yarn, which has been intertwined with gas, using a turret type automatic switching winding device. In the switching winding device, two gas supply lines are installed, one for high pressure and one for low pressure, each gas supply line is connected to the inlet side of a three-way switching solenoid valve, and the outlet side of the three-way switching solenoid valve is connected to a stop valve. An automatic switching winding device for entangled yarn, characterized in that the stop valve and the three-way switching solenoid valve are connected to the gas entangling nozzle through the winding machine, and are configured to operate from the turret start signal of the winding machine via a delay timer. It is in.

In the apparatus of the present invention, the gas supply line may be provided as separate lines for high pressure and low pressure, or may be provided by branching off from the high pressure line via a pressure reducing valve. Gas supply line for high pressure,
If low pressure lines are provided as independent lines, it is possible to supply a different gas to each line. For example, one line can be supplied with air, and the other line can be supplied with humidified air, which has a higher work load than air. and carbon dioxide gas.

[0010] The delay timer adjusts to the turret speed of the winding machine so that the yarn portion that passes through the interlacing nozzle when the gas pressure is changed starts winding from the surface-grained yarn of the full package and becomes the bunch winding portion of the package. Set to match the timing of yarn delivery.

FIG. 1 is an explanatory diagram showing the relationship between various parts of an example of the apparatus of the present invention. A gas supply line 3 equipped with a pressure reducing valve 1 and a gas supply line 4 equipped with a pressure reducing valve 2 are provided, and both gas supply lines are connected to the inlet side of a three-way switching solenoid valve 5. The outlet side of the three-way switching solenoid valve 5 is connected to a gas entangling nozzle 7 via a stop valve 6, and is provided with a pressure gauge 8. A turret start signal from the winder is sent to the three-way switching solenoid valve 5 and the stop valve 6 via a delay timer 9.

Next, the present invention will be explained based on a specific example. In a high-speed spinning system equipped with 18 four-cup turret-type automatic switching winding devices, gas supply lines that supply air whose pressure is regulated by pressure reducing valves are used for high pressure (for high number of entangled yarns) and low pressure (for yarns with a high number of entangled yarns). 2 lines (for low number of entangled yarns)
Air is supplied from both lines to 18 three-way solenoid valves that are activated via delay timers upon receiving the turret start signal from the 18 winders, and from the solenoid valves to one winder via a stop valve. It was configured to supply air to four corresponding interlacing nozzles.

In this high speed spinning series, 70d/24
When producing the nylon 6 yarn f, the number of entanglements was changed from 7 yarns/m to a yarn with 18 entanglements/m, and the yarn was wound. Automatic switching starts when the low entangled yarn of the first winding machine becomes full, and from the turret start signal through a delay timer, the change in the entangled number is determined from the surface of the fully wound package and the winding. Close the stop valve so that it is between the bunch winding part of the first package, operate the three-way switching solenoid valve,
The stop valve was opened and the air pressure was switched from the low pressure side to the high pressure side.

[0014] The package thus obtained had a normal number of entanglements in the used portions of both the low and high entanglement number yarns.

[0015]

[Effects of the Invention] According to the present invention, in a turret type automatic switching winding device, when changing the number of interlacing yarns to be wound before and after the turret, it is possible to eliminate the generation of waste yarn due to changing the number of interlacings. becomes possible.

Furthermore, since no waste yarn is generated, there is no need to wind the waste yarn onto a paper tube as in conventional devices, and the waste yarn from the paper tube into which the waste yarn has been wound can be disposed of, or the paper tube can be recycled. This makes it possible to eliminate the cost of
