Particularly, the present invention relates to a cooling device capable of controlling a surging phenomenon (a phenomenon in which an extreme change in tension occurs in a twisting zone traveling yarn) due to an oil agent attached to the surface of a cooling plate during high-speed false twisting.

発生するようになるため、８００ｍ／分以上の速度で生
産運転することは実質的に困難であった。2. Description of the Related Art In recent years, the processing speed has been increased in order to improve the productivity of false twisting. As the processing speed is increased, the running yarns may have a so-called saging phenomenon. Since a phenomenon occurs and fluff, yarn breakage, twist unevenness, etc. occur, it has been practically difficult to carry out the production operation at a speed of 800 m / min or more.
【０００３】特に加工速度を高速にした場合、熱セット

全体を汚したり、本来の冷却作用も十分発揮できない欠
点がある。Further, when the processing speed becomes as high as 1000 m / min, the liquid (oil agent) applied to the yarn is shaken off and scatters due to the centrifugal force generated by the high speed rotation. There are drawbacks that the oil droplets adhere to surrounding devices and stain the entire machine, or the original cooling action cannot be sufficiently exerted.

くなる。In addition, the running resistance when the yarn passes through the oil droplets and the puddle increases, and the twist twisted at the false twist portion does not reach the upstream side, that is, the heater. However, this makes it impossible to obtain sufficient bulkiness (crimping) performance.

It is an object of the present invention to provide a cooling device for a false twisting machine, which enables effective twisting at high speed by retroactive twisting, suppression of surging phenomenon, and the like.

In a false twisting device in which a heating device, a cooling device, and a twisting device are arranged in this order between the feed roller and the second feed roller, the cooling device is divided into two in the yarn advancing direction, and the upstream side The front cooling device of No. 1 is composed of a contact cooling plate, its length is 0.1 to 0.5 m, and it is forced on the yarn running surface of the cooling plate by passing from the running surface to the back surface. The cooling device for a high-speed false twisting machine is characterized in that a plurality of suction holes communicating with the suction means are provided along the yarn traveling direction.

をへたのち系外に除去される。The yarn heated by the heating device enters the front cooling plate of the cooling device together with the accompanying flow, but the accompanying flow contains water and oil (oil agent), and this is the plate. When it is cooled by the wall surface of the passage, it liquefies rapidly and becomes oil droplets. In addition, the oil that adheres to the yarn is generated by centrifugal force due to high-speed rotation twisting or is squeezed to form oil droplets.The oil droplets generated by such high-speed traveling yarns are the surrounding air and the accompanying flow. At the same time, it is sucked into a hollow portion inside the cooling plate by a suction hole formed in the yarn passage, and is removed to the outside of the system after passing through a separation device through a suction nozzle.

1 and 2 (b) are a longitudinal sectional view and a lateral sectional view of the front cooling device of FIG. 1, respectively. An apparatus for false twisting polyester fibers made of polyethylene terephthalate will be described as an example, but the present invention is not limited to this. It goes without saying that it is applied to other synthetic fiber yarns, etc.

置５が設けられている。In the figure, 1 is a first feed roller and 2 is a second feed roller. A first heating device (first heater) is provided between these first and second rollers. 3 and a twisting device 4 are provided, and a cooling device 5 is provided between the first heater 3 and the twisting device 4.

部６ｂに通ずる吸引孔６ｄが複数個設けられている。The cooling device 5 is configured to include a longitudinal contact type cooling plate having a yarn running path in which a curved concave portion is formed, and is divided into two parts in the yarn advancing direction. The front cooling device 6 on the upstream side of the cooling plate 6 is composed of a cooling plate 6a having a hollow portion 6b therein, and is hollow at appropriate intervals in the longitudinal direction along the central portion of the yarn running path 6c formed in a concave shape. A plurality of suction holes 6d communicating with 6b are provided.

発生する如くされている。At one end of the cooling plate 6a is provided a suction nozzle 6e which communicates with an exhaust device such as a vacuum device or a blower which is a suction source, and through the suction nozzle 6e, from the suction hole 6d to the yarn running path 6c. It is designed to generate a suction flow in or near the area.

のものにするのが好ましい。The rear cooling device 7 on the downstream side is of the same type as the above-mentioned front cooling device 6 having suction holes,
Alternatively, it may be of a different type, but a contact type is preferable.

It is necessary to make it 0.5m.

ましくない。If the length is less than 0.1 m, the suction effect (forced suction of oil droplets) is small, and if it exceeds 0.5 m, the suction capacity and the number of holes increase, but the effect does not change. This is not preferable because it tends to cause deterioration of yarn quality such as generation of fluff.

の長さより大きくしてもよい。The rear cooling plate 7a is mainly for further cooling and stabilizing the yarn after sucking and removing oil droplets generated from the yarn or the accompanying flow in the front cooling plate 6a. The length is made larger than the length of the front cooling plate 6a, but the length is preferably 0.7 to 1.3 m. If it is less than this, the necessary cooling may not be performed, and even if it exceeds 1.3 m, the effect does not change so much, but problems such as enlargement of the device and deterioration of quality may occur. If the processing speed is further increased, it may be longer than this length.

ある。８は供給糸パッケ−ジ、９は巻取装置である。This is because the temperature of the air surrounding the yarn, that is, the temperature of the associated flow increases as the processing speed increases, so it is important how to suck the associated flow and reduce the oil droplets generated, and to cool the front part. This is because it is effective to remove the generation of oil droplets or remove oil droplets by performing suction action with the plate 6a. Reference numeral 8 is a supply yarn package, and 9 is a winding device.

It may be appropriately determined depending on the usage conditions such as landscape orientation and location. Further, the yarn running path is preferably grooved, but it may be flat. In such an apparatus, the yarn y unwound from the supplied yarn package 8 is taken up by the first feed roller 1 and false twisted by the heating device 3 and the twisting device 4. The yarn y that has exited the heating device 3 enters the cooling device 5, where oil droplets and associated flows generated in the front cooling plate 6a are sucked and further cooled and stabilized by the rear cooling plate 7a. After that, the false twisting process is performed by the twisting device 4, and the false feed is performed by the second feed roller 2. Then, it is wound by the winding device 9.

When it is cooled by the wall surface of the passage, it liquefies rapidly and becomes oil droplets. In addition, the oil that adheres to the yarn is generated by centrifugal force due to high-speed rotation twisting or is squeezed to form oil droplets.The oil droplets generated by such high-speed traveling yarns are the surrounding air and the accompanying flow. With the suction hole 6d, the hollow portion 6 inside the cooling plate is also provided.
It is sucked into b and removed outside the system through the suction nozzle 6e. In this case, the oil may be separated or collected.

That is, in a normal contact type heater, the oil smoke generated by contact and resistance on the heater is exhausted, and the desorbed substance of the thread oil agent remains as a heater, but this is a few days. A heater cleaning process will be provided later. On the other hand, in the case of a high temperature non-contact type heater, there is no contact resistance in the heater portion, and of course the heater
There is no le. However, the cooling device under the heater is a contact type
In the case of the plate, the oil agent or its desorbed substance adheres to the plate, causing the above-mentioned various troubles.
