BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sizing liquid filtering device in a warp sizing machine equipped with a size box and a cavity box.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Application Publication No. Sho 63-63 discloses a sizing liquid filtering device for a warp sizing machine equipped with a size box and a cavity box.
The one described in Japanese Patent No. 126964 has been known. In this device, a vertical tubular case is interposed in a glue pipe provided to send the glue liquid in the cavity box to the size box, and a large number of perforated plates (filter media) are superposed in this tubular case at predetermined intervals. The glue liquid sent from the cavity box flows upward from the lower side of the tubular case, and the fluff, the glue residue and the like in the glue liquid are caught by the perforated plate during that time.

Further, in Japanese Patent Application Laid-Open No. 1-298270, a cylindrical filter (filter material) is horizontally and rotatably provided so as to be immersed in a paste solution in a cavity box, and flows into the inside of the cylindrical filter. The paste is formed so as to be sent to the size box, and the fluff etc. captured on the surface of the cylindrical filter is brought into contact with the upper part of the cylindrical filter and squeezed with a rotating squeeze roller, and then scraped with a brush roller to a dust container It is disclosed that the payment has been made.

[0004]

The filter in which the perforated plates are formed by stacking the perforated plates described above is easily clogged with fuzz or the like in the perforated plates, and the perforated plates are removed from the tubular case in order to clean the perforated plates. It was necessary to remove it, and cleaning this perforated plate was troublesome. In addition, in the case of using a cylindrical filter, the sludge mixed with fluff and starch residue is scraped out with a brush roller, so this sludge is scattered and the area around the cavity box is soiled, and the upper half of the cylindrical filter is in the air. Since it is exposed, there is a problem that the upper surface space of the cavity box is narrowed, workability is deteriorated, and the glue liquid adhering to the surface of the cylindrical filter is likely to be dried and become a glue lees.

According to the present invention, a filter medium which has captured solids such as fluff and starch residue is automatically cleaned without stopping the gluing work to improve the filtration efficiency and prevent clogging and further sludge. It facilitates the treatment of the above, prevents the generation of starch cake, and enables downsizing of equipment.

[0006]

A glue liquid filtering device for a warp sizing machine according to the present invention is a warp sizing machine in which a sizing solution is circulated between a cavity box and a size box. In the paste pipe for sending the paste liquid to the box, the raw liquid chamber on one side of the cleaning screen is placed in the cavity box by interposing the closed case for filtration, which is divided into two chambers by the cleaning screen inside.
The filter chambers on the opposite side are respectively communicated with the size boxes, and a separation device for scraping off sludge on the cleaning screen is provided in the stock solution chamber, and the lower end of the stock solution chamber and the upper part of the cavity box are scraped as described above. The glue solution containing a large amount of sludge that has been dropped (hereinafter referred to as sludge-containing glue solution) is connected to the cavity box by a return pipe, and the bag filter attached to the end of the cavity box side of this return pipe is connected to the cavity box. It is characterized in that it is soaked in the paste solution inside.

The cleaning screen provided in the above-mentioned closed case for filtration is preferably a fine mesh of 80 to 100 mesh. In addition, the bag filter attached to the return pipe has a mesh size of 20 to 50, which is coarser than that of the cleaning screen described above.
A mesh cloth or wire mesh is preferred. The above-mentioned cleaning screen is preferably formed in a vertical cylindrical shape, and the upper and lower ends thereof are closed to form a filter chamber inside and a stock solution chamber outside, respectively. In this case, the cylindrical cleaning screen is preferable. A separating device can be provided with a brush that swivels along the surface. Further, it is preferable that an electromagnetic on-off valve is interposed at a connection end of the return pipe on the stock solution chamber side and the valve is intermittently opened to return the sludge-containing paste solution to the cavity box.

Instead of returning the sludge-containing glue solution in the stock solution chamber directly to the cavity box, a glue reservoir is provided between the stock solution chamber and the cavity box, and the lower end of the stock solution chamber and the upper portion of the glue reservoir are connected to each other. , The sludge-containing paste solution is connected to the paste reservoir by a return pipe that can be returned to the paste reservoir, and the bag filter attached to the end of the paste pipe on the paste reservoir side is immersed in the paste liquid in the paste reservoir. The glue liquid in the glue reservoir filtered by the bag filter can be returned to the cavity box.

[0009]

[Function] When sizing is applied to the warp in the size box, fluff and other solid matter that has fallen off from the warp mixes into the sizing liquid, which overflows from the size box into the cavity box together with the sizing liquid, and then passes through the sizing liquid pipe It is sent to the stock solution chamber of the closed case for filtration. Then, the filtered glue liquid filtered by the cleaning screen is sent to the size box. on the other hand,
The sludge containing the above-mentioned solid content and glue lees and the like captured on the cleaning screen is scraped off by the separator and settled in the lower part of the stock solution chamber, and the paste solution containing a large amount of this sludge (sludge-containing paste solution). Is sent to the cavity box by the return pipe, and only the size liquid filtered by the bag filter at the end of the return pipe is returned to the size liquid in the cavity box.

In this case, since the bag filter is immersed in the glue solution, the glue dregs in the sludge that has entered the bag filter gradually dissolves back into the glue solution and passes through the eyes of the bag filter to pass through the bag filter. Disperse in the outside glue,
It is sent to the size box through the paste pipe and the closed case for filtration, and only the above solid content is left in the bag filter. Therefore, when the bag filter is pulled up, a relatively small amount of sludge which is relatively free flowing can be taken out. When the warp yarn is running just above the cavity box, a glue reservoir is provided separately from the cavity box, and when the bag filter is immersed in the glue liquid in the glue reservoir, the warp yarn The bag filter can be attached / detached at a place away from, and the operability is improved.

However, when the cleaning screen is coarser than 80 mesh, the glue lees in the glue solution may pass through to the size box, and when it is finer than 100 mesh, the glue solution with high concentration may be used. When using, the filtration resistance tends to be excessive. Also, the bag filter has 20 eyes.
If it is coarser than the mesh, large solids pass through the bag filter and return to the paste solution. On the other hand, if it is finer than 50 mesh, the paste solution does not easily escape and sludge easily overflows from the bag filter. .

[0019]

As described above, according to the invention described in claim 1, the above-mentioned glue liquid is filtered through the sealing case for filtration in the glue liquid pipe for feeding the glue liquid from the cavity box to the size box. Since it is filtered with a cleaning screen in a closed case and this filtered glue solution is circulated to the size box,
The size box is supplied with a completely filtered and clean glue solution, and the eyes of the cleaning screen in the filtration closed case are always cleaned by the separating device. The above-mentioned filtration can be performed efficiently without any clogging.

On the other hand, the sludge-containing glue solution containing a large amount of sludge such as fluff captured by the cleaning screen in the closed case is stored in the cavity box through the bag filter immersed in the glue solution in the cavity box. Since it is returned to the size liquid, the size residue in the sludge that has entered the bag filter is dissolved and reduced to the size liquid, and only the fluff and other solids that are not reduced to the size liquid remain in the bag filter. Therefore, the sludge obtained by pulling up the bag filter has a lower viscosity than conventional ones, is easy to handle, and has a small amount.

Further, since both the cleaning screen and the bag filter described above are immersed in the paste solution,
The glue liquid adhering to these is not dried to form glue lees. Then, the sludge attached to the cleaning screen is automatically peeled off and sent to the bag filter, so it is not necessary to clean the cleaning screen, and only the bag filter needs to be cleaned. Since only the solid content remains, this cleaning can be done about once a day. Moreover, since the bag filter is immersed in the paste solution, the sludge does not scatter around the cavity box.

Further, in the invention described in claim 2, instead of returning the sludge-containing paste solution containing sludge deposited in the stock solution chamber of the closed case for filtration to the cavity box, a paste storage tank different from the cavity box is used. Since the glue solution which has been passed through the bag filter and which has been immersed in the glue solution in the glue reservoir is returned to the cavity box, the same effect as that of the invention according to claim 1 can be obtained, and the cavity can be obtained. When the warp yarn is running just above the box, the bag filter can be attached and detached at a place away from the warp yarn, and the operability is improved.
