Description

[Detailed description of the invention] (Industrial application field) This invention uses pressurized liquid to suction and capture yarn, and the suction gun drains the yarn to thread the yarn at a desired location. The present invention relates to a waste yarn processing device that processes waste yarn and waste yarn.

(Prior art and its problems) In order to thread the running thread onto a desired location, such as a godet roller, winder bobbin, thread guide, etc., the running thread is suctioned and captured by a pressurized liquid. A movable suction gun is used. When using such a suction gun, a waste thread processing device is provided to separate waste thread from waste liquid from the suction gun.

Among such waste thread processing apparatuses, an apparatus using pressurized water as the pressurized liquid is disclosed in Japanese Utility Model Application No. 195865/1983, and its outline is shown in FIG. In the figure, this waste yarn processing device 1 includes a dehydration tank 2
and a drainage tank 3 provided coaxially so as to surround the dehydration tank 2. Among these, a large number of small holes 2a are provided on the wall surface of the dehydration tank 2.

In this waste thread processing device 1, waste water and waste thread S from a suction gun (not shown) are discharged to a dewatering tank 2 through a recovery hose 5. Then, this dehydration tank 2 is rotated by the drive motor 4 in the α direction in the figure, and only the waste water flows out into the drainage tank 3. In this way, the waste thread S separated from the waste water is transferred to the dewatering tank 2.
The wastewater accumulated inside the wastewater treatment apparatus 1 and flowing out into the wastewater tank 3 is discharged to the outside of the waste thread processing apparatus 1 through a drainage hose 6.

However, in such a waste thread processing apparatus 1, most of the waste threads S separated from the waste water are concentrated near the inner wall surface of the dehydration tank 2 due to the rotation of the dehydration tank 2. Therefore, the space in which the waste threads S are accumulated in the dehydration tank 2 is only a limited space near the inner wall surface thereof, and it is not possible to accumulate a large amount of waste threads S in the dehydration tank 2. For this reason, it is necessary to carry out the waste thread transport work frequently to dispose of the waste thread S in the dewatering tank 2 to the waste thread accumulation area, which poses a problem in that the work efficiency of the thread threading work as a whole is reduced.
Moreover, most of the dewatered waste threads S accumulated in the dehydration tank 2 absorb water newly discharged into the dehydration tank 2. Therefore, not only the dewatering efficiency decreases, but also the load on the drive motor 4 increases as the amount of waste thread S accumulated in the dewatering tank 2 increases.
This requires a relatively high-output drive motor 4, which is economically disadvantageous.

(Purpose of the invention) This invention is intended to overcome the above-mentioned problems in the conventional technology, and is an economically advantageous waste thread processing device that is capable of accumulating a large amount of waste thread to improve work efficiency. The purpose is to provide

(Means for Achieving the Object) In order to achieve the above-mentioned object, in the waste thread processing apparatus of this invention, there is provided a draining tank having a large number of small holes, and a thread at a predetermined angle with respect to the bottom surface of the draining tank. An inclined plate-like body is provided, and the liquid and waste threads are discharged from above the plate-like body toward the surface thereof.

In addition, in this invention, the large number of small holes includes meshes and the like.

(Example) Fig. 1 and Fig. 2 respectively show a thread hanging device 1 incorporating a waste thread processing device which is an embodiment of this invention.
00 is a front internal layout view and a left side view. However, in FIG. 2, the suction gun 105 is not shown. Moreover, FIG. 3 is an enlarged sectional view of a dehydration tank provided in the waste thread processing apparatus and its upper part.
Note that in this embodiment, pressurized water is used as the pressurized liquid. The configuration of the threading device 100 will be described below with reference to these figures.

Note that this threading device 100 has a threading device main body 10.
6 and a suction gun 105. Of these, the threading device main body 106 has the outer shape of a wagon, and is placed on a trolley 102 to which wheels 101 are attached, making it movable.

This cart 102 is provided with a water storage device 110, a pressurizing device 120, a waste yarn processing device 150, and the like. Among these, the water storage device 110 is
2 is provided with a water storage tank 111 fixed to the lower part thereof. This water storage tank 111 is for storing the working water W to be supplied from the threading device main body 106 to the suction gun 105. This suction gun 105 has a configuration as disclosed in, for example, Japanese Utility Model Application No. 61-25360, and detailed explanation thereof will be omitted here.

Next, the pressurizing device 120 will be explained. This pressurizing device 120 includes a low pressure pump 121 and a high pressure pump 122 placed on the trolley 102. Among these, the low-pressure pump 121 communicates with the inside of the water tank 111 through a water supply hose 123, and pumps up and pressurizes the working water W stored in the water tank 111. Pressurized working water W
is sent to the radiator 124. A fan 126 rotated by a motor 125 is arranged at a position facing the radiator 124, and a fan 126 is disposed in a position facing the radiator 124.
air-cooled.

The working water W cooled by the radiator 124 is sent to the high pressure pump 1 via the water supply hose 127.
Sent to 22nd. This high pressure pump 122 includes
High pressure hose 129 that supplies pressurized working water W to the suction gun 105 via the pressure regulating valve 128
and a discharge hose 130 that returns excess water to the water storage tank 111. Further, the pressure regulating valve 128 adjusts the discharge pressure of the working water W from the high pressure hose 129 according to the operation amount of the pressure regulating valve 131, and when the discharge pressure of the high pressure pump 122 is excessive, a part of the pressurized water is diverted. The hose 132 has the function of circulating the water back to the water tank 111 .

Next, the waste yarn processing device 150 placed on the trolley 102 will be explained. This waste yarn processing device 150 includes a drainage tank 153 and a dehydration tank 152 disposed therein. This dehydration tank 15
A large number of small holes 155 are provided in the wall surface of 2, and the inner wall surface thereof is covered with a bag 156 made of cloth, such as taffeta or non-woven fabric.

Further, near one corner of the dehydration tank 152, a collision plate (plate-shaped body) 157 is provided which is inclined at a predetermined angle θ with respect to the bottom surface of the dehydration tank 152. This collision plate 157 is formed of, for example, a stainless steel plate. In addition, a hook 158 is integrally formed on the upper end of the dehydration tank 1.
It is attached to 52. Furthermore, this collision plate 1
57, a collection hose 154 is connected to the fixture 19.
It is fixed by 0. The waste water and waste thread S discharged from the suction gun 105 are discharged from above the collision plate 158 to the surface thereof through the recovery hose 154.
It is starting to collide with 8. In addition, drainage tank 1
53 communicates with the water tank 111 through an outflow hose 158. The working water W flowing into this water storage tank 111 is used for circulation.

Furthermore, a handling bar 1 is provided on the trolley 102.
81 is attached by a hinge 182.
Therefore, as shown by arrow A, the handling bar 181 is of a collapsible type so that its upper portion can protrude to the outside of the wagon body 180. Therefore, if the handling bar 181 is pulled down and then manually pulled to move the threading device 100, the wheels 101 of the cart 102 will not hit the operator's feet.

Next, the threading device 10 having the above configuration will be explained.
The processing of waste thread S when threading is performed using thread thread 0 will be explained.

First, the threading device 100 is placed at a point where threading is to be carried out, for example, near the bobbin of a winder.
After moving and placing, the suction gun 105 supplied with pressurized water from the pressurizing device 120
The yarn (not shown) is captured by suction and threaded onto the bobbin of a winder. Suction gun 1
The waste water and waste threads S from 05 collide with the surface of the collision plate 157 through a recovery hose 154 fixed above the collision plate 157, and then flow down into the dewatering tank 152 along this surface. Then, the waste water flowing out from the dehydration tank 152 to the drainage tank 153 is returned to the water storage tank 111, and S is accumulated in the dehydration tank 152.

When threading is carried out one after another by repeating the above procedure, the waste threads S will be stirred up by the force of the inflowing drainage water until there is not much waste thread S accumulated in the dewatering tank 152.

On the other hand, the drainage water after colliding with the collision plate 157 is mixed with the collision plate 157 when flowing over the collision plate 157.
A fan-shaped water film is formed around the point of collision.
Then, the waste water that has formed a water film in this way flows down to the bottom of the dewatering tank 152. Then, due to this water film, the accumulated waste threads _S1 are pushed upward as shown by arrow B (Fig. 3).

Then, the waste yarn S ₁ accumulated in the dehydration tank 152
However, when it is pushed up by the water film created by the inflowing wastewater, the waste threads newly discharged with the wastewater S ₂
will crawl under the accumulated waste thread S ₁ . In this way, in the dehydration tank 152, the newly discharged waste threads _S2 are sequentially replaced with the accumulated waste threads.
It crawls under _S1 and accumulates.
Therefore, in the accumulated waste threads _S1 , natural dehydration (gravity dehydration) is started from the waste threads at the top. When discarding the waste threads S, it is sufficient to sequentially take out only the upper waste threads that have been sufficiently dehydrated from among the waste threads _S1 accumulated in the dewatering tank 152.

By the way, in order to push up the waste thread S ₁ by the water film in this way, a collision plate 157 is installed in the dehydration tank 152.
When installing the bottom of the dehydration tank 152 and the collision plate 1
It is desirable to select the angle θ formed by 57 as appropriately as possible. Although this varies depending on the scale of the dewatering tank 152 and the water pressure of the drainage water, normally it is sufficient to set the angle between about 30° and 60°, preferably about 45°.

By dewatering and accumulating the waste yarns S in the manner described above, a relatively large space within the dehydration tank 152 can be used for accumulating waste yarns. For this reason,
The burden of transporting the waste threads S in the dewatering tank 152 to the waste thread collection site and disposing of them is reduced. Moreover, since the waste thread S after dewatering is pushed upward, it does not absorb waste water again. Furthermore, since this dehydration tank 152 does not require a driving motor or the like, the structure is simple and economical.

Further, as described above, by lining the dehydration tank 152 with a cloth bag 156, this bag 15
6 plays the role of a filter. For this reason, small hole 1
Almost no waste threads S are mixed into the wastewater flowing out from the dehydration tank 152 through 55, and especially when the working water W is recycled as in this embodiment, the effect of preventing clogging of the circulation waterway by the waste threads S is effective. be. Furthermore, if the bag 156 is made disposable, the dehydration tank 1
The work of taking out the waste yarn S in the bag 52 is also very simple because it is only necessary to replace the bag 156 with a new one.

Here, the fixture 190 will be explained. FIGS. 4 and 5 show a fixture 190, respectively.
FIG. 2 is a partial plan view and a cutaway sectional view of FIG. Also, the 6th
FIG. A and FIG. 6B are both explanatory views when fixing the recovery hose 154 with the fixing device 190, with FIG. 6A showing before fixing and FIG. 6B showing after fixing.

In these figures, the fixture 190 has a hollow cylindrical shape and has a hole 190a in the axial direction. A fixture 190 is attached to the upper surface of the wagon body 180 with bolts 183 so that this hole 190a is coaxial with the hole 180a provided in the wagon body 180.

This fixture 190 has a flange pipe 192 and a hollow tightening nut 193 that are screwed together.
A hollow bush 191 made of an elastic material such as nylon is inserted inside near the threaded portion 198 with the bushing 93 . This bush 19 has a substantially trapezoidal cross-sectional shape in the axial direction, and a ring-shaped slit 194 is provided on the inner wall surface to facilitate deformation. In addition, flange pipe 1
The upper inner wall surface 195 of the bolt 92 and the lower inner wall surface 196 of the tightening nut 193 are both tapered to widen toward the opening.
5,196 sandwich the bush 191 in the vertical direction in FIG.

When the recovery hose 154 is fixed using the fixing device 190 configured in this manner, the following effects occur. First, as shown in FIG. 6A, with the tightening nut 193 and the flange pipe 192 separated by a certain distance in the axial direction, the recovery hose 15 is
4 is inserted into the hole 190a. Thereafter, the tightening nut 193 is rotated to advance the screw engagement in the x direction in FIG.
Reduce the distance in the x direction between 5 and 5. Then, the bush 191 is compressed in the x direction by the squeezing force from the lower inner wall surface 196 and the upper inner wall surface 195, and is elastically deformed in the y direction (centripetal direction) (FIG. 6B). As a result, Bushu 191
The inner wall surface of the recovery hose 154 presses the outer wall surface of the recovery hose 154 in the centripetal direction, and the pressure force causes the recovery hose 15
4 is closely fixed to this fixture.

When the recovery hose 154 is fixed with the fixing device 190 as described above, there is no need for a joint, so there is an advantage that clogging due to waste threads S passing through the recovery hose 154 does not occur.

By the way, in the above embodiment, the waste yarn processing device 15
Although a single dehydration tank 152 was provided in the 0, by providing a plurality of dehydration tanks 152, waste water and waste threads S can be separated more effectively.
Therefore, in the case where two dehydration tanks 152 are provided, the differences from the above will be explained below.

FIG. 7 shows two dehydration tanks 152, 152a, 1
It is a top view when 52b is installed in succession. 8 and 9 are a sectional view and a sectional view, respectively, of FIG. 7. Note that in FIG. 7, illustration of the bag 156 is omitted.

In these figures, each dehydration tank 152a, 15
2b are arranged in a row with their respective longitudinal directions parallel to each other. Further, although not shown, a drainage tank is provided to surround these dehydration tanks 152. In each dehydration tank 152a, 152b,
A collision plate 157 is attached to each of them as in the previous embodiment.

Dehydration tanks 152a, 152 connected in this way
A discharge pipe 186 that can freely turn in the direction C in a horizontal plane is provided above the middle part of b, and the recovery hose 154 is connected to the discharge pipe 186 by a joint 185.
is connected to.

As mentioned above, two dehydration tanks 152, 152a,
When waste threads are accumulated in the waste thread processing device to which the waste thread processing device 152b is connected, first, the discharge pipe 186 is rotated to position its discharge port 186a above the collision plate 157 attached to the dehydration tank 152a. after that,
When threading is performed, waste threads are accumulated in the dewatering tank 152a, as described in the previous embodiment. When the dehydration tank 152a is filled with waste threads, the discharge pipe 186 is rotated and the dehydration tank 152a is filled with thread waste.
The discharge port 186a is positioned above the collision plate 157 attached to 2b (imaginary line L), and threading is continued. As a result, the dehydration tank 1 filled with waste yarn
Since no drainage water flows into the dehydration tank 152a, the waste yarn in the dehydration tank 152a is naturally dehydrated during the period when the dehydration tank 152b is used for threading. Then, the waste threads in the dehydration tank 152a are discarded, and when the dehydration tank 152b is filled with waste threads, the dehydration tank 152a is used again.

As described above, the two dehydration tanks 152 and 15
If 2a and 152b are used alternately, the dehydration tank 15
It becomes possible to sufficiently dehydrate all the waste threads in 2.

By the way, this invention is not limited to the above-mentioned embodiment, and the following modifications are also possible.

In the above embodiment, the dehydration tank 152 and the collision plate 15
7 is made separately, but they may be integrally molded.

When selecting and using multiple dehydration tanks,
The discharge pipe may be rotated as in the above embodiment, or a discharge pipe having a removable joint may be fixedly arranged in each dehydration tank, and the recovery hose may be connected to this joint. In this case, it is preferable to use a detachable joint (so-called one-touch coupler).

The waste yarn processing device according to this invention may be provided on a single truck together with the pressure device and the water storage device as in the above embodiment, or it may be provided only on a separate truck. Of course, a fixed arrangement is also possible.

It goes without saying that the waste yarn disposal device of this invention is also effective in a yarn hooking device that does not circulate the working fluid.

(Effects of the invention) As explained above, according to this invention, a large amount of waste threads can be accumulated in the dewatering tank by providing a plate-like body that causes the wastewater and waste threads to collide in the deliquid tank. As a result, it is possible to prevent a decrease in work efficiency, and also to obtain an economical thread waste disposal device with a simple configuration.
