(57) [Summary] [Purpose] In the process of removing water by suction air flow,
It is to improve the water removal efficiency. [Composition] A woven woven cloth is brought into contact with a water removal roll having a water removal port, and a cover is provided on the outer surface of the woven fabric to cover the outer surface of the woven fabric at a position corresponding to the suction port. The water-removing effect is enhanced by suctioning through the fibers of the woven cloth.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for removing water from a woven woven fabric in a water jet loom.

[0002]

[Prior Art]

 Japanese Unexamined Patent Publication No. 50-168 discloses that an air suction device connected to a roll having a suction port on the winding side through an air / water separating device removes water adhering to a woven fabric by an air flow. Disclosure.

However, according to the apparatus, in the thin woven fabric, most of the suction air passing through the fibers of the woven structure passes through the gaps between the fibers and is effective in removing the moisture adhering to the fibers. However, the efficiency of removing water is deteriorated and sufficient water removing function cannot be obtained. Further, even in the case of a thick woven fabric, since the fiber density is higher than that of a thin woven fabric, the action of removing water by the suctioned air flow is recognized, but it was not sufficient.

[0004]

[The purpose of the device]

 Therefore, an object of the present invention is to improve the water removal efficiency in the process of removing the water by the suctioned air flow.

[0005]

[Means for solving the problem]

 To achieve the above object, the present invention wraps a woven fabric woven on a water removing roll having a suction port around the suction port and makes contact with the woven fabric. An impermeable cover that covers the upper surface is provided, and most of the sucked air flow is sucked through the fibers of the woven fabric to enhance the water removal effect.

【Example】

 FIG. 1 shows a water removal device 1 in a water jet loom in relation to the path of a woven fabric 2. The sheet-shaped warp yarns 3 intersect with the weft yarns 4 at the weft 5 to form the woven fabric 2. The woven cloth 2 is wound around the outer circumference of the water removing roll 7 while being spread in the weft width direction by the temple 6, and is wound around the outer circumference of the cloth winding roll 19 via the guide roll 8, the winding roll 9, and the guide roll 10. Will be taken.

FIG. 2 shows an enlarged main part. The dewatering roll 7 is in a position in contact with the woven fabric 2 and forms a slit-shaped suction port 11 in the width direction of the woven fabric 2. At the position of the dewatering roll 7, the woven fabric 2 is covered with a flexible cover 12. One end of the cover 12 is rotatably supported by a holder 13 by a support shaft 14 in a fixed position. The cover 12 is made of an air-impermeable material and forms a surface of the winding portion of the water removing roll 7 that is in contact with the woven fabric 2. The dewatering roll 7 is connected to a steam separator 17 and an air suction device 18 such as an air blower or an air pump by a connection pipe 16 located below.

During weaving, that is, in the process in which the woven fabric 2 is wound up, the air suction device 18 brings the inside of the water removing roll 7 into a negative pressure state by the suction operation of air, and the suction port 11 is sucked in the suction direction. Generate an air flow.

The air flow at this time passes through the inside of the fibers of the woven fabric 2, removes water in the fibers in the process of passing, and reaches the steam separator 17 in a state of containing water, where the air flows. And water. The cover 12 helps the air flow to enter the inside of the suction port 11 through the fibers of the winding portion of the woven fabric 2. The flow rate of the air flow through the fibers of the woven fabric 2 increases when the air resistance of the fibers reaches the suction port 11, and thus decreases when the woven fabric 2 is near the suction port 11. Since the increase in the flow velocity due to the decrease in the cross-sectional area of the air flowing through the gap is greater, the air flow passing through the woven fabric 2 efficiently carries the moisture adhering to the fibers into the water removing roll 7.

When the cover 12 is not present, the air flow passing through the center of the void of the yarn of the woven fabric 2 directly enters the water removing roll 7 without being involved in the water removing function. On the other hand, when the cover 12 is present, the airflow directly entering from the gap between the threads of the woven cloth 2 disappears, and the airflow flowing into the suction port 11 always passes through the inside of the fibers of the woven cloth 2. Directly participates in the water removal function and flows into the suction port 11. Therefore, this air flow always acts on the fibers of the woven fabric 2 to effectively take in moisture. As described above, the presence of the cover 12 significantly improves the water removal effect as compared with the conventional one for the above two reasons.

The cover 12 ′ of the present invention may have a large number of recesses formed on the surface in contact with the winding portion of the woven fabric 2 as in the other embodiment shown in FIG. In the cover 12 ′ having a large number of recesses formed therein, as in the case of the flat cover 12 of the above-described embodiment, external air is sucked into the suction port 11 through the fibers of the winding portion of the woven fabric 2. In addition, the cover 12 'does not adhere to the winding portion of the woven fabric 2 over the entire surface, and damage to the moving woven fabric by the cover 12' is reduced.

[0012]

[Effect of the device]

 In the present invention, a cover is provided to cover the upper surface of the winding part before and after the suction port of the water removing roll, and since there is a woven cloth between the water removing roll and the cover, the external air flow is not directly applied. It does not enter the inside of the suction port through the gap of the woven fabric and always passes through the inside of the fiber of the woven fabric from the large area of the winding part covered with the cover, so the water removal effect is enhanced.

Other Embodiments The cover 12 'of the present invention may be formed with a large number of recesses 15 on the surface in contact with the winding portion of the woven cloth 2 as in the other embodiment shown in FIG. Like the flat cover 12 of the above-described embodiment, the cover 12 ′ having the large number of recesses 15 allows external air to be sucked into the suction port 11 through the fibers of the winding portion of the woven fabric 2. In addition, the cover 12 'does not adhere to the winding portion of the woven fabric 2 over the entire surface, and damage to the moving woven fabric 2 by the cover 12' is reduced.
