Description

[Detailed description of the invention] (Industrial application field) The present invention is applicable to the following:
The present invention relates to a running yarn suction collection device that allows threading work and waste yarn storage to be easily performed.

(Prior art) In order to thread the traveling yarn onto a desired location, such as a godet roller, a bobbin of a winder, a yarn guide, etc., a movable threading suction device that captures and suctions the traveling yarn is used. Generally, pressurized air or pressurized water is used as the working fluid for the thread hooking suction device. Among them, when pressurized water is used,
A waste thread disposal device is provided at the end of the discharge hose of the thread hooking suction device for storing and disposing waste threads and waste water so as not to leak them to the outside.

As a running yarn suction collection device equipped with such a waste yarn processing device, for example,
The method disclosed in Japanese Utility Model Application Publication No. 119545/1983 is known.

Of these, the former device has an auxiliary thread threading suction device concentrically provided on the top of the thread threading suction device body, so that the running yarn is removed from the thread threading suction device body at the initial stage of suction. This allows the yarn to be smoothly guided to the suction port, and for the above-mentioned waste yarn disposal, a wire mesh container is connected to the rear end of the suction device body for thread hooking with a hose. In addition, the latter device sucks and discharges waste yarn discharged from multiple bobbins using a suction device that uses pressurized water as a working fluid, and then processes the waste yarn and waste water in a discharge channel configured in a ring shape. It is something to do.

However, with the former device, if the equipment to be threaded is spread over a wide area, the working fluid supply/discharge hose is connected from the working fluid production device to the threading suction device, so there is an emergency when threading. Not only did this require a long hose to be swung around, which was extremely inefficient, but there were also certain restrictions on the range in which the thread could be hung.

Furthermore, since the latter device is a stationary type in which the entire processing device is fixed on the floor, it cannot withstand use when the equipment to be threaded is spread out over a wide area as mentioned above. It wasn't.

In these conventional devices, when the waste thread is transferred from the waste thread processing device to the transfer vehicle, the water contained in the waste thread becomes water droplets on the floor of the work site and dissipates, and the dissipated water droplets are not completely disposed of. Otherwise, the water droplets may cause workers to slip, creating an unfavorable working environment for safety.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems, simplifies the threading work, and provides a suction collection device for running yarn that is highly safe in waste thread processing work. The purpose is to

(Means for Solving the Problems) In order to solve the above-mentioned problems, the running yarn suction collection device according to the present invention includes: (a) a thread hooking suction device that sucks the running yarn; (b) a pump that supplies pressurized water to the threading suction device; (c) a pump that also separates the yarn and water discharged from the threading suction device and stores the separated yarn; a waste yarn storage and treatment tank; (d) a water supply tank that combines the storage of water separated in the waste yarn storage and treatment tank and the storage of water supplied to the pump; (e) the pump and the waste yarn storage treatment. a tank, and
The present invention is characterized by comprising: a movable cart for loading the water tank; and (f) hoses connecting the thread hooking suction device, the waste thread storage and treatment tank, and the thread hooking suction device and the pump, respectively. do.

(Embodiment and operation) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The drawing is a longitudinal cross-sectional view showing an embodiment of the running yarn suction collection device according to the present invention.

In the figure, reference numeral 1 denotes a waste yarn processing device, in which a processing tank 8 having a lid 3 is loaded on a moving cart 10. Inside the processing tank 8, yarn Y discharged from a yarn suction device (not shown) through a discharge hose 2 connected to a lid 3 is collected as waste yarn 4, and waste water 5 is collected from this waste yarn 4. It is equipped with a dehydration tank 9 that separates and dehydrates water by centrifugal force, a water storage tank 11 that temporarily stores the separated waste water 5, a motor 13 that rotates the dehydration tank 9, and its universal joint 12. In addition, in the present invention, dehydration refers to removing water until the water content of the waste thread 4 becomes 30% or less.

The dehydration tank 9 is provided with a large number of openings 9a in order to remove the dehydrated water from inside the dehydration tank 9. In this embodiment, an example is shown in which centrifugal dehydration is performed as the dehydration tank 9, but the waste yarn 4 may also be dehydrated by press dehydration.

Between the rotating shaft of the dehydration tank 9 and the water storage tank 11,
A mechanical seal member that seals the leakage of the drainage water 5 and also serves as a bearing for the rotating shaft, or
A seal member 14 such as a labyrinth seal member is fitted. Note that the rotation axis of the dehydration tank 9 is
The arrangement is not limited to the vertical arrangement as shown in the figure, but may be arranged horizontally. When the rotating shaft is arranged horizontally, it is necessary to support the dewatering tank 9 from both ends, but since the motor 13 can be installed without intervening the water tank 11, there is no need to worry too much about leakage of the waste water 5 from the bearing part. This has the advantage of simplifying wastewater treatment since there is no need to use water.

Further, 18 is a water supply tank which has both the function of storing the waste water 5 and the function of storing water for reusing the waste water as a working fluid for the thread hooking suction device, and is fixed on the movable trolley 10. There is. The water tank 18 and the water storage tank 11 are connected to a pipe 17 with a certain head difference so that the waste water 5 in the water tank 11 flows into the water tank.
are connected to each other. 19 is a pump for pressurizing the drainage water in the water supply tank and then supplying this pressurized water to the threading suction device as a working fluid for threading through the water supply hose 20; Fixed.

That is, the above-mentioned device provides the movable trolley 10 with
A water tank 18 having a water pressure pump 19 for supplying working fluid to the thread hooking suction device via a water supply hose 20
and a dehydration tank 9 that stores the waste thread 4 discharged from the thread hooking suction device via the discharge hose 2 together with the working fluid after use, and dehydrates the water in the waste thread 4.
and a water storage tank 11 for temporarily storing the waste water 5 that has passed through the dehydration tank 9, and the temporarily stored waste water 5 is returned to the water supply tank 18 and reused as pressurized water. It constitutes a series of suction collection devices that allow threading of threads and treatment of discharged waste threads and waste water, and also constitutes a circulation system for working fluid.

Next, the operation of the device shown in the figure will be explained.

The waste yarn Y sucked up by the suction device for threading was used as a working fluid for the suction device for threading through a discharge hose 2 provided at the rear end of the suction device for threading, passing through the lid 3. It is discharged together with pressurized water and enters the dehydration tank 9 within the processing tank 8. The dewatering tank 9 is rotated at high speed by the rotational force of the motor 13 and the universal joint 12. Due to the centrifugal force caused by the high speed rotation of this dehydration tank 9, the dehydration tank 9
The water absorbed and adhering to the waste threads 4 stored inside is dehydrated. The dehydrated water falls into the water storage tank 11, and is temporarily stored in the water storage tank 11 as waste water 5 together with the used working fluid, and then flows down through the piping 17 into the water supply tank 18, where it is operated. Water is stored as raw fluid water.

On the other hand, after the yarn suction operation is completed, the dehydrated waste yarn 4 is taken out by opening the lid 3, and is directly stored in the waste yarn collection area.

If such an embodiment device is used, the moving trolley 10
Since a set of pressurized water production equipment, drainage and waste thread processing equipment is mounted on top of the machine, it can be moved freely to the desired location for threading, which significantly improves the efficiency of threading work. Further, by providing the dewatering tank 9, most of the supplied working fluid can be recovered as waste water 5, and can be reused as the working fluid for the thread hooking suction device. Furthermore, since the waste threads 4 have been dehydrated, the transport work to the waste thread collection site becomes extremely easy, and a large amount of waste threads can be transported at one time. Furthermore, since there is no water droplet falling from the waste thread 4 at the work site, the work environment is improved from a safety standpoint.

Next, the example device was used in a take-off process at a silk manufacturing site.

Using pressurized water with a pressure of 150 kg/cm ² as the working fluid of the thread hooking suction device to which the waste thread processing device 1 is connected,
A 70D-24f x 8 yarn nylon filament running at a yarn speed of 5200 m/min was captured and suctioned by a threading suction device, and the threading operation was carried out to the Godet roller and to the winder. During that time, the yarn Y, which will become the waste yarn 4, discharged from the yarn hooking suction device together with the used working fluid is stored in the dehydration tank 9 of the waste yarn processing device 1, and is sufficiently dehydrated.

(Effects of the invention) Since the invention of the present application has the above-described configuration, it can produce the excellent effects described below.

(1) The entire set of equipment required for threading, such as a pump, waste thread storage tank, and water supply tank, is compactly packed and loaded on a mobile trolley, and the threading suction device and these equipment are connected with a hose, so that the Godet roll, winder, etc. You can freely move to the desired threading location. In addition, the work of transporting the waste threads to the waste thread collection site becomes extremely easy, and a large amount of waste threads can be transported at one time. Therefore, the processing device can turn in a small radius, and the threading work efficiency is significantly improved.

(2) Also, unlike stationary equipment, there is no need to separately install dangerous and expensive high-pressure piping networks, drainage pits, etc. to obtain pressurized water, so the action radius of the thread hooking suction device is not widened. Of course, the equipment cost is significantly reduced.

(3) The wastewater that is dewatered from the waste thread in the waste thread storage tank is collected in the water supply tank and reused as water supply for the pump, which not only saves water resources, but also eliminates water droplets from the waste thread at the work site. The working environment will be improved from a safety perspective.
