Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a device for applying an oil agent to a melt-spun yarn of synthetic fiber.
More specifically, the present invention relates to an elevation metering oil supply and discharge nozzle device capable of changing the oil supply height position at which an oil agent is applied.

[0002]

2. Description of the Related Art In recent years, high-speed spinning has become widespread, and melt-spun yarns are, as shown in FIG. 6, located 1.8 m from a spinneret 39 at a position of a metering discharge oil supply nozzle 1 for applying an oil agent, for the purpose of eliminating yarn unevenness. It has been placed in the vicinity. However, now that the variety of products has been diversified, the conventional single yarn thickness deviates from 3 to 4 decitex, and 1 decitex with a small single yarn thickness to 5 decitex or more with a large thickness has come to be produced.

[0003] Usually, for the purpose of eliminating yarn unevenness, an oil agent is quickly applied after cooling, converged and guided to a take-up portion. For this oiling agent application position, it is inevitable to change the range of the single yarn thin type close to the base by about 1 m, and the thick type 2.5 m away from the base.

For this reason, conventionally, as shown in FIG. 6, the metering / discharging and refueling nozzles are arranged at an upper position 43 and a lower position 44.
Equipment was prepared so that the equipment could be installed at various locations, and the equipment was installed either above or below, depending on the product type.

Usually, the number of spindles is large in the yarn making equipment, and the work for removing the device is a long work, so that the oil supply pump is stopped and the hoses individually connected to the metering discharge oil supply guides are removed, and then the device is removed. Remove and relocate. In addition, the hose connected to the metering / discharging and refueling nozzle is replaced with a hose of a length that is at a height at which the route of the hose must be secured with an ascending slope so that air can be vented. For example, when the connecting hose when the device is arranged above as shown in FIG. 7 is attached to the device moved to the lower part as it is, the hose route 45 meanders greatly and the climbing slope cannot be taken, and the fuel pump is operated. However, even if it passes through the metering oil discharge nozzle, the air does not escape completely, the oil supply cannot be metered and discharged, the prescribed oil agent does not adhere to the yarn, causing thread breakage, yarn unevenness, and decrease in elongation. It becomes a product defect.
