Description

[Detailed Description of the Invention] The present invention relates to an apparatus in which running yarn is treated with compressed fluid to give the yarn cohesiveness by interlacing single filaments.

False-twisting machines that use long heaters, such as high-speed false-twisting machines, or stretch false-twisting machines that have a directly connected stretching section, become textile machines that are significantly taller when the equipment units are arranged vertically in series. This will significantly impede workability such as threading.

Therefore, it is known to reduce the overall height and improve workability by separately arranging each unit of a textile machine in the front and back.

For example, the false twisting section is arranged as the front unit and the winding section is arranged as the rear unit, and after the false twisted yarn that has been false twisted in the front unit runs parallel to the floor surface, it is wound up in the rear unit. Wind it up into sections.

Therefore, workers must always be extremely careful not to get caught in the yarn running on the floor, and it is known to provide a platform above the yarn path to avoid this.

On the other hand, if multifilament yarns, including not only false-twisted yarns but also straight yarns, are used as they are on a knitting loom, they will become fluffed, resulting in a decrease in quality, or may even stop. The above disadvantages can be avoided in an economical manner by providing the above-mentioned information.

Incorporating such a fluid treatment device for single yarn entanglement into either the front unit or the rear unit increases the height of the device, impairs workability, and impedes the overall compactness of the device. becomes.

For this reason, this problem can be solved if the fluid treatment device can be installed at the bottom of the platform, which is essentially a dead space, but on the other hand, since it is located at the bottom of the platform, it becomes difficult to thread the fluid treatment device. will occur.

In other words, normally, when threading a thread between the front and rear units, the thread is first threaded onto the front unit, and then the running thread is transferred to the rear unit through a thread path parallel to the floor surface. You need to hang a thread on it.

Generally, when a running yarn is hung on a fluid treatment device, a fluid treatment device having a yarn hooking slit in which a part of the yarn guide portion of the fluid treatment device communicates with the outside is used, and in addition, the fluid treatment device is The thread is often threaded without stopping the fluid while it is being sprayed.

Therefore, it is much more difficult to thread a running thread onto a fluid treatment device that is spraying fluid than when threading a thread onto a normal hot plate, hollow heater, or the like.

In addition, the slit for threading normally needs to be as narrow as possible within the range that allows threading, taking into consideration the thickness of the thread to prevent the thread during fluid treatment from jumping out of the thread path. This is also one of the reasons why it is more difficult to thread a fluid processing device than to thread a normal hot plate, hollow heater, etc.

Furthermore, when threading a fluid processing device that does not have the above-mentioned thread threading slit, in principle it is sufficient to pass the thread from the thread entrance to the thread exit in the same way as threading a hollow heater. The thread path of the processing device is much smaller than that of a hollow heater, and the internal structure is often complicated, so thread threading workability is much more difficult than that of the thread threading slit mentioned above. That's funny.

The purpose of the present invention is to provide a fluid processing device for running yarn with good workability, which solves the above-mentioned problems of making textile machines more compact and thread threading workability to the fluid processing device. be.

In an apparatus in which units of a textile machine are arranged in front and behind each other, and the yarn supplied from the front unit is transferred to the rear unit parallel to the floor surface, the yarn path of the yarn running section parallel to the floor surface is A fluid processing device for running yarn is provided with a fluid processing device, a plat is provided to cover the upper part of the yarn path of a yarn running section parallel to the floor surface, and the platform is cut out at a portion corresponding to the fluid processing device. The device is characterized by:

The present invention will be explained in detail below using embodiments shown in the figures.

The figure shows an embodiment of the present invention for a draw-twisting machine.

In FIG. 1, 1 is an undrawn yarn package, 2 is a yarn feeding roll, and 3 is a stretching roll. Between the yarn feeding roll 2 and the stretching roll 3, a heater 4 for heat setting and a false twisting spindle 5 are installed. They are arranged in this order.

The undrawn yarn Y from the undrawn yarn package 1 is stretched between the yarn feed roll 2 and the stretching roll 3, and is subjected to false twisting by the false twist spindle 5.

Next, the yarn is subjected to heat treatment by a heater 7 in a relaxed state between the drawing roll 3 and the yarn feeding roll 6.

After processing, the false-twisted curled yarn runs parallel to the floor surface between the yarn rerolls 6 and 8, and then turns upward again from the yarn feed roll 8 and is wound up by a winder.

In this case, the yarn feed rolls 2 and 6, the drawing roll 3, the heaters 4 and 7, and the false twisting spindle 5 become the front unit, and the yarn feed roll 8 and the winder 10 become the rear unit.

A plat 11 is installed to cover the upper part of the portion where the false-twisted curled yarn runs parallel to the floor between the yarn feed roll 6 of the front unit and the yarn feed roll 8 of the rear unit.

Further, a fluid treatment device 9 is installed on the yarn path running under the bracket 11, and a single yarn entanglement process is performed by jetting compressed air.

However, as shown in FIG. 2, the platform 11 is cut away only at the portion corresponding to the fluid treatment device 9, so that the fluid treatment device 9 can be directly viewed from above the bracket.

As shown in FIG. 2, the bracket 11 is made up of a plurality of plates spread over each other, so that an operator can ride on this platform 11 and carry out operations such as threading.

Further, a notch 12 is provided in the plate constituting the bracket 11, and the plate can be opened and closed by touching this notch 12.

Therefore, if necessary, threading to the fluid treatment device 9 can be carried out by opening the plate of this platform 11.
This makes the work even easier.

The present invention is generally applied to false twisting machines and stretch false twisting machines, but the spinning machine units are arranged in front and behind each other, and the yarn is transferred between the front and rear units by running parallel to the floor surface. It can also be applied to spinning take-up machines, stretch take-up machines, etc. that have a similar structure.

As mentioned above, according to the present invention, by arranging the fluid treatment device in the substantially dead space portion at the bottom of the platform, it is possible to prevent the overall height of the device from increasing and make it more compact. By cutting out the portion corresponding to the processing device, threading workability can be facilitated, and problems specific to threading the fluid processing device can be avoided.

In addition, the fluid treatment equipment has nozzles and nozzles that become dirty during use.
This can cause problems such as the occurrence of abnormalities due to such factors, and problems such as the yarn jumping out of the fluid treatment device during processing if the device has a thread hanging slit, but with this invention, the operator can directly see the fluid treatment device. Therefore, abnormalities can be easily detected.
