Abstract

PURPOSE:To efficiently dehydrate and dry a woven fabric in a wet state regardless of density of weaving. CONSTITUTION:In dehydrating and drying woven fabric woven by a water jetting weaving machine, a suction roll 2 which is made by covering the outside of a meshed cylindrical filter composed of metal fibers or synthetic resin fibers with a water absorbing cover such as chammois leather or woven fabric and rotatably connected to a center pipe linked through a flange to a vacuum cleaner 11 is installed at the downstream side of a reed 1. The tip of the woven fabric in a wet state is introduced into a space between a dehydrating column 3 and a squeezing roll 15 which is arranged so as to be brought into contact with both the suction roll 2 and the dehydrating column 3 to remove water by pressing. The woven fabric is successively guided to a space between the suction roll 2 having a weight roll 14 placed on the top and the dehydrating column 3, and water is absorbed by the water absorbing cover and discharged as drain through a center pipe to the outside. Then warm air is blown from a blow nozzle 13 by a warm air generator set between the vacuum cleaner 11 and the blow nozzle 13.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dewatering and drying apparatus for a woven cloth woven by a water jet loom on the machine.

[0002]

2. Description of the Related Art Conventionally, a woven cloth is made to pass over a slit-shaped elongated hole of a dehydrating cylinder provided on a loom, and air is sucked from the slit-shaped elongated hole to dehydrate the woven cloth. , I was winding it while drying naturally. However, in the case of a woven fabric with a coarse density, only air is absorbed and sufficient dehydration cannot be performed, and in the case of a woven fabric with a high density, it is not possible to perform sufficient dehydration because it is difficult to suck the air itself Was insufficient.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a woven cloth is made to pass between a suction roll covered with a water-absorbent cover and a dewatering cylinder, and compressed water is absorbed by the cover of the absorbent roll. Then, suck the air in the suction roll and collect the absorbed moisture into the suction roll, guide it to the steam separator through the pipe, discharge the moisture as drain, and discharge the wind through the blow nozzle to the woven cloth. Spray on and dry.

EXAMPLE In FIG. 1, a warp yarn (a) is woven immediately after a reed (1) to form a woven fabric (b), which passes between a suction roll (2) and a dewatering cylinder (3), and a pushing roll. It is sandwiched between (4) and the take-up roll (5) and sent out, and then wound up by the cloth winding roll (7) via the pushing roll (6). The suction roll (2) is connected to the steam separator (9) via the suction duct (8), is connected to the suction hole of the vacuum cleaner (11) via the intermediate duct (10), and is connected to the suction cleaner (11). The exhaust hole is an exhaust duct (1
It is connected via 2) to the blow nozzle (13). The weight roll (14) is placed on the upper part of the suction roll (2) to enhance the squeezing force of the suction roll (2) and the dehydrating cylinder (3).

In FIG. 2, the wet woven cloth (b) passes between the suction roll (2) and the dehydration cylinder (3), and the weight roll (14) is placed on the suction roll (2) and dehydrated. The squeezing power with the tube (3) is increased. Squeeze pipe (1
5) is arranged so as to be in contact with both the suction roll (2) and the dewatering cylinder (3), and the wet woven fabric (b) passes through to enhance the squeezing force as if wedges bite.

The construction of the dewatering roll (2) will be described with reference to FIG. A cover (2) made of a water-absorbing material such as chamois or woven cloth is provided on the outer surface of a cylindrical filter (2a) formed by molding metal fibers or synthetic resin fibers into a mesh shape
The center pipe (2d), which is covered with b) and has flanges (2c) fixed to both ends of the cylindrical filter (2a) to keep airtightness and the ventilation hole is cut, is fixedly installed on the loom body. , The flange (2c) is rotatably supported by the center pipe (2d), and the stopper ((2e)
Prevents the lateral slippage.

Next, the operation will be described. Woven cloth (b) when weaving is squeeze pipe (15) and dewatering cylinder (3)
Woven cloth (b) by passing while being pressed between
The water contained in the woven fabric (2) is squeezed out and then passes between the suction roll (2) and the dehydrating cylinder (3) while being squeezed, whereby the residual water contained in the woven fabric (b) is absorbed by the suction roll ( It is sucked up by the cover (2b) of 2). Since the inside of the center pipe (2b) is in a vacuum state by suction of the vacuum cleaner (11), the cover (2
The residual water absorbed by b) is absorbed by the cylindrical filter (2
After passing through the ventilation hole cut from a) to the center pipe (2d), it is collected inside the center pipe (2d), reaches the steam separator (9), and the water is separated and discharged to the outside as a drain. Only vacuum cleaner (11)
Be led to. This air is blown out from the blow nozzle (13) and is applied to the dehydrated woven fabric (b) to accelerate the drying. Here, it is also possible to install a warm air generator between the vacuum cleaner (11) and the blow nozzle (13) to obtain more sufficient drying. By the way, it is obvious that the wet woven cloth (b) can be passed between the squeeze pipe (15) and the suction roll (2) to squeeze out the water.

[0008]

As described above, according to the present invention, after the moisture contained in the woven cloth (b) is once absorbed by the cover (2b),
Since it is introduced into the suction roll (2), the water content can be dehydrated regardless of the density of the woven fabric.
