Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a yarn processing device whose interior is filled with a processing medium, and more specifically, the present invention relates to a yarn processing device whose interior is filled with a processing medium. The present invention relates to a yarn processing device.

[Prior Art] Conventionally, for example, it has been possible to obtain yarn with further improved quality by passing the yarn through a container filled with a processing medium such as pressurized air, heated air, or heated liquid. Many inventions related to yarn processing devices (hereinafter referred to as yarn processing devices) have been made.

In such a yarn processing device, in order to minimize the amount of processing medium leaking from the yarn processing device to the outside, the following points are considered: (1) whether to seal the yarn entrance/exit; The big problem was whether the threading work could be done easily.

For example, as a solution to the above problem (■),
A yarn processing device disclosed in Japanese Patent No. 8-24759 is known. This yarn processing device has a slit formed on the side of the device body over the entire length in the yarn running direction, and this slit is connected to the yarn entrance and exit via both ends of the yarn processing device. Although the yarn hook has the advantage of being easy to remove, the slits at both ends do not have any closing members, so even if it is not used for high-pressure, high-temperature processing media, there is a large amount of media leakage. A problem remained.

On the other hand, in order to solve both the above-mentioned problems (1) and (2), yarn processing devices such as those disclosed in Utility Model Publication No. 45-31.786, Japanese Patent Publication No. 60-1425, and even Japanese Patent Publication No. 60-500138 have been developed. The main body of the device is divided into a plane that includes the thread passage, so that it can be opened and closed freely, and the planar precision of this divided face is finished with high precision to prevent the processing medium from leaking from inside, or a seal member surrounding the thread passage is used. A yarn processing device that attaches and seals the thread has been proposed.

However, in devices with a split surface that opens and closes, the pressure-receiving area of the lid is large, so even a small amount of internal pressure causes an extremely large force to act on the lid, so large-scale tightening to resist this force is difficult for the mechanism. There are issues that require it.

On the other hand, Japanese Unexamined Patent Publication No. 59-144672 proposes a processing device in which a thread passage and a thread threading passage are formed by rubbing surfaces of two members having recesses on their surfaces.

1. In this device as well, the force acting on the dividing surface can be relatively reduced, but it is difficult to manufacture the rubbing surface with high accuracy over the entire length of the yarn processing device, especially when the entire length of the yarn processing device is This problem becomes more pronounced as the length increases.

Therefore, it is difficult to say that any of the above-mentioned conventional devices is a yarn processing device that solves both the sealing performance and threading workability.

[Problems to be Solved by the Invention] The present invention solves the problems of the prior art described above, and improves both the sealing performance of the processing medium filled inside the thread processing device and the workability of threading the thread into the thread processing device. It is an object of the present invention to provide a yarn processing device with improved performance.

[Means for Solving the Problems] The structure of the present invention for solving the above problems is as follows. That is, a yarn processing container is provided with a processing chamber in which openings and exits for the yarn are formed at both ends, and a processing chamber filled with a medium at a pressure higher than atmospheric pressure for processing the yarn. A side surface and both ends of the processing container are opened from the processing chamber to the outside,
and a processing container in which a continuous slit is formed that is also connected to the inlet/outlet of the yarn, and of the continuous slit,
A yarn processing device comprising: a closing member that closes a slit formed on a side surface;
The yarn processing apparatus is characterized in that the slits at both ends of the processing container are closed with detachable closing members.

Here, the processing container of the present invention includes a processing chamber filled with a yarn processing medium such as pressurized steam, heated pressurized air, heated water, and a heating medium, and has both ends thereof. This is a yarn processing container in which a yarn inlet/outlet is formed, and the yarn is run through the inlet into the container, exposed to a processing medium, and then taken out from the outlet to produce yarn with further improved yarn quality. It is a container for obtaining.

The external shape of this processing chamber is not particularly limited, and may be cylindrical or rectangular.

In order to facilitate the threading operation into the container, the processing container is provided with a continuous slit that extends from the side surface of the container through both ends to the entrance and exit port for the yarn, and is closed with a closing member. .

The opening width of this continuous slit is preferably narrow to seal the processing medium in the processing chamber, if sealing with a closing member is prioritized, but if it is too narrow, it will not only be difficult to thread the thread, but also cause slit processing. In addition, if the opening width is too wide, the force acting on the closing member against the internal pressure will increase, making it impossible to obtain a tight closing state, so the practical opening width is 0.
It is preferably 1 to 3°0 mm, more preferably 0
It is preferable to set it as 5-1.5 mm.

The thickness of this slit, that is, the distance from the processing chamber to the opening at the tip of the slit, may be the same as the wall thickness of the processing container, but in this invention, water vapor at a temperature of about 110 to 140°C is usually used as the processing medium. (0.5 to 2 at saturation pressure
．． A high temperature fluid (approximately 5 kg/cnf) is often used, and the heat held by this processing medium is often transferred to the closing member through the slit portion and thermally deteriorating the closing member, so this should be prevented. Therefore, the dimensions are such that sufficient cooling is achieved during the heat transfer process from the processing chamber to the seal section.

This dimension is preferably 10 to 100 mm, more preferably 15 to 50 mm. To form a slit of this size, for example, (1) when manufacturing a processing container, the outer shape of the processing container is formed into a convex shape and a slit is provided in the convex portion, (2) after manufacturing a prismatic processing container, Welding the slit part of the convex part, or attaching two L-shaped members to the opening of a processing container with a concave cross-section so that they can be replaced with the blades on the outside. It's fine. The dimensions of the entrance and exit of the yarn may be the same as the opening width of the slit, but may be changed as appropriate in consideration of the yarn diameter and friction caused by vibrations during introduction and extraction of the yarn.

However, regarding the thickness of the slit, for example, by making the yarn entrance/exit a blocking part or by providing a labyrinth part, the leakage of the processing medium from the yarn entrance/exit can be sealed as much as possible to improve the sealing effect. In order to achieve this, the thickness may be made somewhat thicker than the thickness of the slit on the side surface.

In addition, the closing members provided in the slits on the sides and both ends of the processing container can effectively seal the processing medium, and in addition, the closure members are easy to attach and detach, so that the yarn can be easily hung and removed. desired.

In order to effectively seal the processing medium, among the slits, the distal end of the side slit should be in such a way that the distal end of the slit, that is, the contact portion with the closing member effectively contacts the closing member. For example, it is preferably formed into an edge shape formed at a constant acute angle, a convex shape, a concave shape, a flat shape, etc.

In addition, as for the material of the closing member, the processing medium may be pressurized steam,
Hardness 50-9 for pressurized heated air, heated liquid, heat medium, etc.
A rubber-like elastic body with a temperature of about 6 degrees is preferable, and other known rubber-like elastic bodies having heat resistance, water resistance, acid resistance, alkali resistance, oil resistance, fatigue resistance, etc. are used depending on the type of processing medium. be able to. In addition, for special applications, copper,
Aluminum, stainless steel, or an alloy thereof may also be used.

In addition, as a method for closing the slits on the side and both ends, the above-mentioned closing member is formed into a plate shape, an edge shape, a rod shape, a cylinder shape, etc. with a dimension slightly narrower than the opening width of the slit, and the closing member is placed inside the slit. Methods include inserting the slit, or molding the slit to a width sufficiently wider than the opening width of the slit, and closing the opening while pressing it.

When inserting a plate-shaped member into a slit, the fitting tolerance between the slit at both ends and the plate-shaped member is required so that the closing member can be easily inserted into the slit at both ends and the processing medium is tightly sealed. You should be careful. When both materials are metal-based, good results can be obtained by setting the gap between them to about 5 to 50 μm. In particular, regarding the structure of the closing member for the slits at both ends of the processing container, since there is an entrance/exit for the yarn in these parts, it is difficult to effectively seal the processing medium compared to the slits at the side parts. In addition to the method, by press-fitting a wedge-shaped plate member into a guide groove opposed to each other through a slit in a direction substantially perpendicular to the running direction of the yarn,
For example, the force of the wedge in the direction of the slit may be used to bring the wedge into close contact with the opening of the slit to close it.

The yarn processed by this yarn processing device includes, for example, thermoplastic fibers such as multifilament and monofilament, but by appropriately changing the shape of the inlet and outlet, it is possible to process sheet materials such as fabrics and films. It can also be applied to

The above-mentioned effects of this device can be achieved when the number of processing systems is multiple,
This is most obvious when the processing medium is a pressurized gas such as pressurized steam or a pressurized liquid, and the processing chamber is in a pressurized state and high sealing performance is required, but it is also possible to use oil, acids, alkalis, etc. The present invention can also be preferably applied to processing media that would cause problems if they leaked out, such as chemical liquids and heated liquids.

It goes without saying that the present invention can also be preferably applied to cases where yarns are treated in a vacuum.

[Function] When threading, the yarn processing device of the present invention first removes the closing members that close the slits on the side and both ends of the processing container, and then threads the continuously running yarn. For example, the yarn is drawn out from the outlet while being sequentially introduced in the longitudinal direction of the processing chamber along the opening slit from the entrance of the yarn while being taken up by a suction means such as a suction gun.

At this time, the yarn is configured such that the slit extends from the side surface of the processing container, through both ends, and to the entrance/exit of the yarn, so that it can be easily threaded into the processing chamber without disassembling the processing container. Ru.

Next, after the slit on the side surface of the processing container is closed with a closing member, the processing container is filled with a processing medium, and the yarn is subjected to a predetermined yarn treatment. The closing member provided in the slit reliably seals the leakage of the processing medium through the slit against the internal pressure of the processing medium.

In order to remove the yarn from the processing container, the closing members provided on the side surface and both ends are removed, thereby removing the thread without disassembling the processing container.

[Example] Hereinafter, an example of the present invention will be specifically described based on the drawings.

FIG. 1 is a partially cutaway perspective view of a yarn processing device according to the present invention, in which a yarn Y is provided inside a processing chamber 2 of a processing container 1.
is introduced from the upper inlet 3, travels downward, and is led out from the outlet (not shown).

In the figure, the processing container 1 is a columnar container that is long in the running direction of the yarn Y, and its cross-sectional shape has a length of 1 from the processing container.
It is formed in a convex shape with one convex portion 4. and,
A processing chamber 2 with a rectangular cross section is provided inside and filled with a processing medium for improving the quality of the yarn, and the convex portion 4 includes:
A slit 5 opened to the outside from the processing chamber 2 is provided in the running direction of the yarn Y, and further reaches the entrance/exit of the yarn.

The slit 5 has an opening width δ of 0.5 mm.

The slit thickness A'l, that is, the length from the processing chamber 2 to the tip of the slit 5, is 38 mm, and the tip of the slit 5 is formed in a figure 7 shape with an angle of 90 degrees. Further, a heat insulating material 6 is wrapped around the outer periphery of the processing container 1, and an exterior plate 7 formed in a prismatic shape is further wound around the outer periphery.

In addition, end plates 10 are fixed to the processing container 1 with bolts (not shown) at both ends of the processing container 1 via rubber packings 9 in order to close the slits 8 (FIG. 2) at both ends of the processing container 1. . And this end plate 1
0 is also provided with a thread inlet/outlet 3 and slits 11 at both ends, which correspond to the thread inlet/outlet of the processing container 1 and the slits 8 at both ends. Reference numeral 12 denotes an L-shaped bracket erected from the processing container 1 with the end plate 10 in between, and although it is omitted in the figure, a seal plate 3 is placed between the bracket 12 and the end plate 1o.
5 (FIG. 13) is used to seal the slit 11 by detachably inserting it.

On the other hand, 13 is a plate-shaped lid, which is attached to a hinge 14 supported from the processing container 1 so as to be openable and closable. A rubber gasket 16 with a figure-7 cross section is attached to the cover 13 in a replaceable manner at a position where the slit 5 on the side surface and the figure-7 groove 15 on the end plate are in close contact with each other when the cover is closed. When the lid 13 is closed, it is brought into close contact with the slit 5.15 to form a seal. Although not particularly shown in the drawings, the lid 13 and the exterior plate 7 are fitted with a lock such as a known snap lock so that a tightening force is applied to the rubber gasket 16 in the closed state. There is. Note that 17 is a snail guide for stabilizing the thread path of the yarn Y at the entrance/exit portion of the processing device.

Next, FIGS. 2 to 6 are diagrams showing details of the inlet and outlet of the processing medium into the processing container 1. FIG. 2 is a longitudinal cross-sectional view of the main part of the yarn processing device shown in FIG. 1 as viewed from the direction of arrow X-X, and FIGS. FIG. 7 is an example diagram showing an inlet and an outlet in another embodiment, and is a longitudinal cross-sectional view, a rear view, and a rear view of the inlet, respectively.
FIG. 3 is a plan view and a longitudinal cross-sectional view of the outlet.

In FIG. 2, reference numerals 18 and 19 are a processing medium supply pipe and a discharge pipe provided on the back side of the processing container 1 (on the opposite side to the position where the slit 8 is provided), and the valves 18 and 19 are not shown. The supply or discharge amount is adjusted by opening and closing operations. Reference numeral 20 denotes a collision plate provided so that when the processing medium is introduced into the processing container 1, the processing medium is diffused and rectified before being introduced.

The discharge pipe 19 is used to discharge drain, impurities, residual air, etc. immediately after the processing medium is supplied, to discharge surplus processing medium, and also to discharge the processing medium from the processing chamber 2 when the supply of the processing medium is stopped. This is a discharge pipe for smoothly discharging the processing medium remaining inside and returning it to the atmosphere.

In addition to the embodiment shown in FIG. 2, the inlet for the processing medium is provided in the processing container 1 and the end plate 1 as shown in FIGS. 3 and 4.
A rectifying plate 22 may be inserted between the rectifying plate 22 and the processing chamber 1 through rubber gaskets 9 and 21, and fixed to the processing container 1 with bolts (not shown), and the processing medium may be supplied from the rectifying plate 22. The illustrated rectifying plate 22 is provided with slits 23 and V-shaped grooves 24 at positions corresponding to the slits 8 (FIG. 2) at both ends of the processing container 1. In addition, there is a supply pipe 2 for the processing medium on the end face.
5 is connected to the slit 23, and a communication hole 26, which is a passage hole for the supplied processing medium, is provided inside the slit 23 so as to surround the slit 23, and furthermore, on the processing chamber side of the communication hole 26, there is a spout for the processing medium. A plurality of orifices 27 are drilled.

Furthermore, between the slit 23 and the communication hole 26, there is a fin 2.
8 is fixed to the rectifying plate 22 so as to surround the slit 23.

At the processing medium inlet of the embodiment shown in Fig. 2, the medium is supplied almost perpendicularly to the running direction of the yarn Y, which may cause lateral vibration of the yarn Y in some cases. However, if the processing medium is introduced in this manner, a flow can be created along the running direction of the yarn Y, so that no problem of lateral vibration of the yarn occurs. Further, the processing medium supplied from the supply pipe 25 is divided by a plurality of orifices 27 and ejected into the processing chamber, and the ejecting direction is further rectified by the fins 28 in the running direction of the yarn Y, so that it does not come into contact with the yarn Y. is further promoted,
The yarn processing effect is improved.

On the other hand, in addition to the embodiment shown in FIG. 2, the outlet for the processing medium may be
As shown in FIG. 5 and FIG.
It may also be fixed to the processing container 1 with bolts (not shown) after being inserted between the two. A discharge pipe 30 for the processing medium is provided on the end face of the exhaust plate 29, and the discharge pipe 30 and the processing chamber 2 are connected to each other through a small hole 3.
1 is connected. This exhaust plate 29 is also provided with a slit 23 like the rectifying plate 22, and fins 32 are provided so as to surround the slit 23.

In the discharge port of this embodiment, drain, impurities, etc. that have fallen down along the inner wall of the processing container 1 and the slit 5 are discharged from the exhaust pipe 30 through the small hole 31 together with the processing medium.

The discharge port shown in Figure 2 allows drain and impurities to reach the exit of yarn Y, and may touch the running yarn, impairing its quality uniformity, or disrupting its running, resulting in single yarn breakage or complete yarn breakage. This can cause yarn breakage, but if the processing medium is discharged in this manner, the outlet of the yarn Y can be separated from the discharge drain, impurity accumulation, etc., so that it can be produced uniformly without the above-mentioned problems. Quality yarn can be stably obtained.

Next, FIGS. 7 to 10 are sectional views showing various aspects of the closing member for closing the slit 5 in the side surface shown in FIG. 1.

FIG. 7 is a sectional view of the main part of the closing member in the case of this embodiment device, in which the tip angle θ1 of the V-shaped groove 15 of the slit 5 is formed at 90 degrees, and it is fitted into the groove 33 of the lid 13. The rubber gasket 16 is formed with a tip angle θ2 of 80 degrees, so that the two come into close contact when the lid 13 is closed. The tip angle θ1 is not limited to the processing medium, but is usually 40 to 1.
It is preferable that the tip angle θ2 is 50 degrees and the tip angle θ2 is 30 to 120 degrees. In this way, when the relationship between the two is set to θ1≧02, good sealing performance can be obtained. In addition, as another method of closing the slit 5, as shown in FIGS.
As shown in Figure 0, the shape of the abutting surface between the tip of the slit 5 and the rubber seal is flat, arcuate, and inverted V.
character shape (tip angle of slit 5 03 degrees, rubber gasket 34
The tip angle may be 04 degrees) or the like. In the embodiment shown in FIG. 10, the angles θ3 and θ4 of both ends are set as
4, the opening surface of the slit 5 can be closed using the wedge force acting on the slit 5 of the rubber packing 34.

Next, FIGS. 11 to 14 are detailed views of the seal plate 35, which is a member for closing the slits 11 at both ends of the processing container 1 shown in FIG. A perspective view and a vertical cross-sectional view of the seal plate 35, respectively.
13 and 14 are a perspective view and a plan view of the seal plate 35. FIG.

In these figures, 10 is an end plate fixed to the upper surface of the processing container 1 with a bolt (not shown) via a rubber gasket 9, and has a slit 1 connected to the inlet 3 of the yarn Y.
1 is provided, and a V-shaped groove 15 is formed at the tip thereof, similar to the shape of the slit 5 on the side surface. 12 is a bracket with an L-shaped cross section that stands upright from the processing container 1 with the end plate 10 in between, and the lower surface side of the tip part is θ
It is shaped like a wedge with an angle of 5. Reference numeral 35 designates a seal plate for closing the slit 11 on the side surface, and its outer shape has a 7-shaped groove corresponding to the slit 5 on the side surface and a corner 36, and one surface is formed with the bracket 12. Similarly, it is formed into a wedge shape with an angle of θ5, and a rubber gasket 37 is attached to the other surface.

With such a configuration, the yarn Y is arranged in the slit 1.
1, then attach the seal plate 35 to bracket 1.
If the bracket 12 is inserted between the seal plate 2 and the end plate 10 with the inside of the bracket 12 as a sliding surface, a component of the pushing force of the seal plate 35 will be applied to the end plate 1 due to the wedge action.
Since pressing toward 0 acts as a force, the seal plate 3
5 is securely brought into close contact with the slit 11. Also,
Since the seal plate 35 is detachable, the closing operation is very easy. Here, the corner portion 36 of the seal plate 35 serves to position the yarn Y, and by appropriately setting the angle θ5 with the corner portion 36, the opening of the entrance 3 of the yarn Y can be adjusted. Since the area can be adjusted, a narrowed passage for the filament after occlusion can be easily formed.

In the embodiment described above, only one yarn Y is processed, but the present invention can be easily applied to a plurality of yarns.

That is, FIG. 14 shows the case where the number of threads in the processing system is one, whereas FIG. 15 shows the configuration of the seal plate 35 and the end plate 10 when two threads Y are processed at the same time. The inlet 3.3' corresponds to the yarn Y, Y'.
A slit 38 communicating with this inlet is provided in the end plate 1o, and the position of the corner 36 of the seal plate 35 is determined so that only the inlet 3.3' is exposed when the seal plate 35 is inserted and closed. Good. A case where the number of yarns is three or more can be handled in the same way. In the embodiment shown in FIGS. 11 to 15, the slit 11
The narrower the opening width, the better in terms of sealing performance, but if it is too narrow, threading becomes difficult and slit processing becomes difficult, so the practical opening width should be 0.1 to 3 mm. is preferable, and more preferably 0.5 to 1.5 mm.

Next, FIGS. 16 and 17 show the slit 11 in the side surface when the processing medium is relatively high-pressure water vapor.
FIG. 4 is an embodiment diagram in which a plate-shaped member is used as the closing member, and is a perspective view and a plan view, respectively.

In FIG. 16, reference numeral 39 denotes an end plate that is removably bolted (not shown) to the upper surface of the processing container 1 via a rubber gasket 40, and has slits 11 corresponding to the slits 8 at both ends of the processing container. and a V-shaped groove 15 are formed.

In addition, the inner surface of the slit 11 has a thread Y connected to the slit.
An entrance 3 is provided, which is a closed passage. This population 3 communicates with the slit 11, so the thread Y
41 is a plate-shaped seal plate that closes the slit 11, and the bearing 4 protruding from the end plate 39
It is rotatable around the second pin 43. With this configuration, the seal plate 41 can be easily closed by inserting it into the slit 11 while rotating it in the direction of the arrow.

In this case, the thickness of the seal plate 41 is set to 25 μm so that the gap between the seal plate 41 and the slit 11 can be easily inserted and tightly sealed against the slit 11. Further, the screw 44 is for preventing the seal plate 41 from being pulled out by screwing into a female screw 45 provided on the end plate 39 when the pressure of the processing medium is high.

This seal plate 41 is not an open/close type as shown in the figure, but is inserted in the direction of an arrow 47 after the thread Y is inserted into the entrance 3 as shown in FIG. , a sliding type that closes the slit 11 may be used. In this case, in order to obtain a tighter closed state, the seal plate 46 may be tightened from both sides by applying an external force to the tip of the end plate 39 in the direction shown by the arrow 48. Further, in order to prevent the seal plate 46 from being removed from the slit 11, the seal plate 46 may be pushed toward the processing chamber side.

In FIGS. 16 and 17, the case where one yarn Y is processed is shown, but as shown in FIG. Y-
By providing an inlet 3.3' for the slit 11 or providing an inlet 3.3- for the yarn YSY- on both sides of the slit 11, it is possible to easily handle the case where a plurality of yarns are processed.

As described above, according to the apparatus of the present invention, the type of yarn to be processed,
Even if the number of threads changes, as long as you have a simple replacement part to close off unnecessary inlets, you can easily handle changes in the number of threads in the processing system with the same thread processing equipment, and the equipment can be improved. This has the advantage of dramatically increasing the degree of freedom. In these FIGS. 16 to 19, the yarn entrance/exit formed after inserting the seal plate 41.46 is the entrance 3.3'
The processing medium inside the processing container will leak out from this opening. However, the end plate 39.4
By setting the thickness 12 of 6 to an appropriate dimension, the pressure will be reduced due to the wall resistance before the processing medium leaks to the outside, so it will be effective even against relatively high processing media such as the high-pressure water vapor mentioned above. Can be sealed. The preferred 12 dimensions vary depending on the pressure of the processing medium, the thickness of the thread, etc., but are preferably 10 to 100 mm, more preferably 15 to 50 mm. In addition, the shape of the entrance 3.3' when viewed from the direction in which the yarn Y travels is as follows:
The shape should be as close as possible to the cross-sectional shape of the yarn Y, such as an arc, a U-shape, a rectangle, a triangle, an inverted triangle, or a composite shape of these, to prevent unnecessary leakage from inside the processing container. good.

For this reason, for example, if the cross-sectional shape of the inlet 3 is a rectangle as shown in FIG. 16, then the length in the direction along the slit 11 is a, and the length in the direction perpendicular to this is b, then 0 It is preferable to select dimensions a and b so as to satisfy the following relationship: .5≦b/a≦20.

Next, FIGS. 20 and 21 are diagrams showing still another embodiment of closing the entrance and exit of the yarn Y, and are a plan view and a longitudinal cross-sectional view, respectively.

In the closing member of this embodiment, the end plate is divided into two parts, a fixed end plate 51 and a movable end plate 52, and the fixed end plate 51 is fixed to the processing container 1 via a packing 50 with a bolt (not shown). ,on the other hand,
A movable end plate 52 is engaged with a reciprocating actuator 54 supported from the processing container 1 by a bracket (not shown). And this movable end plate 52
By moving the movable end plate 52 forward and backward using the two rod pins 53 provided on the fixed end plate 51 as a guide, the movable end plate 52 can easily slide to the position indicated by the two-dot chain line in the figure using the packing 50 as a sliding surface. .

With this configuration, the fixed side end plate 51 and the movable side end plate 52 can be brought into close contact with each other with a certain pressing force, so that the slit 11 can be easily closed and the entrance and exit port for the yarn Y can be closed. is formed as an obstruction.

Furthermore, in this embodiment and those shown in FIGS. 17 to 19, unlike the one shown in FIG. The length of the closing member including the actuator 54 in the longitudinal direction of the processing container is shortened, making the entire apparatus compact, and rotating rollers (not shown) are usually provided at both ends of the processing container 1. However, there is an excellent effect in that there is no risk of contact with these rollers.

Next, FIG. 22 is a perspective view showing an embodiment in which ease of maintenance of the slits at both ends is further taken into consideration.

In this embodiment, a fixed side end plate 55 having a yarn inlet 3 formed on the side surface A is fixed to both end surfaces of the processing container 1 with bolts 56, and the end plate 55 is fixed to the end plate 55 with bolts 56. The movable end plate 58 connected by the bearing plate 57 is rotatable in the direction of the arrow in the figure about the pin 59 so that the side surface A of the fixed end plate and the side surface B of the movable end plate are in contact with each other. Supported. In addition, the movable end plate 5
A handle 60 is provided on the other end side of 8, and by screwing a male screw 62 formed on the nozzle 60 into a female screw 61 provided on the side part A, both end plates 55
．． 58 can be firmly abutted against each other. A notch 63 and a pawl 64 are provided on the side surfaces A and B of both end plates, respectively, and by engaging the pawl with the notch, the movable end plate 58 is protected from the end surface of the processing vessel due to the internal pressure of the process vessel. This prevents the movement of

Further, seal packings 65 are provided on the contact surfaces between the end plates 55 and 58 and the end surfaces of the processing container so as to cover the slit 5 and the processing chamber 2.

This seal packing 65 is preferably made of a rubber-like elastic body,
In order not to hinder the rotational sliding movement of the movable end plate 58, it is preferable to form it into a lip shape. Further, although the seal packing 65 is provided on the processing container 1 side in FIG. 22, it may be provided on the fixed side end plate 55 and the movable side end plate 58 side.

With this configuration, the rotating direction of the movable end plate 58 is also perpendicular to the traveling direction of the yarn Y, so that the entire entrance 3 can be rotated by the movable end plate without touching the rollers mentioned above. Since the opening can be exposed by rotating the opening, oligomers and the like that have reattached to the entrance 3 can be easily cleaned, and maintenance is very easy. Furthermore, in this embodiment, even if the inside of the processing container is under high pressure, the movable end plate 58 is firmly engaged with the notch 63 of the fixed end plate 55, and is then firmly fixed by the handle 60. Therefore, it has the excellent effect of preventing its movement and also preventing leakage of the processing medium from both end plates and the end face of the processing container.

In addition, in FIGS. 1 to 22 explained above,
At the entrance 3 of the yarn Y, a large amount of oligomers, fuzz, broken yarn, etc. attached to the yarn may be re-attached and deposited, making it impossible to use the processing apparatus itself. In order to eliminate such inconveniences, it is preferable to clean the inside of the inlet 3 using a brush-like cleaning tool or to remove it by spraying a gas or liquid such as air or water.

Further, although the closing members at both ends of the processing container 1 have mainly been described as those provided at the upper part of the processing container, it goes without saying that the closing members provided at the lower part have the same structure as the upper part. Nor.

In the apparatus of this embodiment shown in FIGS. 1, 2, 7, and 11 to 14, the length of the processing container 1 is 500 mm.
mm, the opening width δ of the slit 5 on the side surface is 0.5 mm, and the thickness l! 38mm, end plate thickness 12 20m
The device of this embodiment was constructed by forming the angle θ5 of the seal plate 35 into a wedge shape of 2 degrees.

The pressure inside the processing chamber 2 of this device is 0.5 as the processing medium.
When water vapor of kg/mm2 was supplied and yarn Y with a total fineness of 1000 denier was supplied at a yarn speed of 600 m/min, no steam leaked from the slits 11 at both ends as well as from the slits 5 on the sides. There were hardly any. Furthermore, the amount of leakage from the yarn inlet/outlet 3 was minimal, and no lateral vibration of the yarn due to the supply of the processing medium was observed, which did not pose any hindrance to the continuous treatment of the yarn.

[Effects of the Invention] According to the present invention, the thread entrance and exit ports at both ends of the processing container are narrowed passages, and closing members are provided not only at the side surfaces but also at both ends of the slit provided in the processing container. Therefore, high sealing performance against the medium inside the processing container can be obtained, and energy costs can be reduced.

In addition, the slit is shaped as a continuous slit that connects from the side of the processing container through both ends to the yarn entrance and exit, and the closing members for the slits at both ends are detachable.
In addition to dramatically improving sealing performance against processing media,
Threading work can be carried out continuously without the need to cut one end of the thread or dismantle the processing container when threading the thread into the processing container, as in the past, and the workability and productivity of thread processing are significantly improved. It has excellent effects such as improved performance.
