Description

[Detailed Description of the Invention] This invention relates to an apparatus for submerged processing of fabrics for subjecting long woven fabrics, knitted fabrics, etc. to liquid treatments such as washing and scouring.

The fabric treatment equipment uses a horizontal net conveyor in the liquid tank to spray a treatment liquid onto a long piece of fabric while transporting it in a submerged tank for washing or scouring with almost no tension. The fabric is introduced into a fabric path formed between these two levels of net conveyors in a waveform and transferred, and the processing liquid is sprayed onto the fabric from processing liquid injection nozzles located above and below the fabric. Horizontal liquid processing equipment designed to
Then, the net is fixed in a U-shape in a vertically long liquid tank. An endless net conveyor is installed vertically inside this fixed net, and a U-shaped fabric passage is formed between the fixed net and the net conveyor. Vertical liquid treatment apparatuses are known in which a treatment liquid is injected into a fabric path from inside and from outside of a fixed net.

However, in the above-mentioned horizontal liquid processing equipment and vertical liquid processing equipment, in order to increase the retention amount of the fabric in the liquid and lengthen the retention time, the former is extended in length in the front and back direction, and the latter is In this case, a plurality of liquid tanks had to be lined up, and in both cases, the installation area was large.

In both cases, the fabric floats and moves easily in the fabric passage, so the amount of retention in the fabric passage is partially different, resulting in uneven processing, and there are disadvantages such as meandering in the width direction and wrinkles. there were.

In addition, in the above-mentioned vertical liquid processing apparatus, an outer net conveyor that circulates in a U-shape is provided instead of the fixed net, and a large number of fabric guide plates are installed at equal intervals on this outer net conveyor to suppress floating of the fabric. Attempts were made to install a projecting structure in the
In this case, the only thing that can be done is to make the distribution of the retention amount uniform, eliminate uneven processing, and prevent the occurrence of wrinkles due to meandering.In order to increase the retention amount, it is necessary to install an additional liquid tank, which is different from the conventional vertical type. It was almost the same as the liquid processing equipment.

This invention suppresses the floating of fabric in the fabric passage to prevent uneven processing and wrinkles, and also increases the amount of fabric retained without significantly expanding the installation area.

That is, in this invention, two sets of endless conveyors are installed in a liquid tank with the top open so that some of the conveyors face each other at regular intervals to form a fabric passage and move in the same direction. In the submerged processing apparatus for fabric, in which a plurality of fabric guide plates are protruded from an endless conveyor at equal intervals to partition the fabric passage, and a large number of treatment liquid injection pipes are disposed outside the fabric passage, the above-mentioned A submerged fabric processing device for fabric, characterized in that the fabric passage is composed of one row of vertical fabric passages, and three or more levels of horizontal fabric passages that are connected to the lower end of the vertical fabric passage and rise while reciprocating back and forth. It is.

Examples of this invention will be described below with reference to the drawings.

In FIG. 1, a first endless conveyor 2 is installed in a liquid tank 1.
and a second endless conveyor 3 are stretched in a mutually intricately bent shape, and the two sets of endless conveyors 2, 3
A vertical fabric passage 4a on the supply side faces each other at regular intervals, and a first horizontal fabric passage 4b, a second horizontal fabric passage 4c, and a third horizontal A fabric passage 4 is formed which includes a fabric passage 4d, a fourth horizontal fabric passage 4e, and a fifth horizontal fabric passage 4f.

Note that both the first endless conveyor 2 and the second endless conveyor 3 are constructed by attaching endless chains to both ends of a long net connected endlessly, or by connecting a number of short perforated plates with an endless chain. It has a porous structure that allows the processing liquid to pass through.
The first endless conveyor 2 has a large number of fabric guide plates 5.
are protruded at equal intervals.

A large number of treatment liquid injection pipes 6 are disposed along and outside the fabric passage 4, so that the treatment liquid is injected toward the fabric passage 4.

The first endless conveyor 2 and the second endless conveyor 3 have different widths, and as shown in FIGS. 2 and 3, the former is formed wider than the latter. A first endless chain 2a is attached to the section, and a second endless chain 2a is attached to the ear section of the second endless conveyor 3.
An endless chain 3a is attached to each.

The first endless chain 2a described above is a vertical fabric passage 4.
From the small-diameter drive sprocket 7 at the upper end of a, along the rotational direction of the first endless conveyor 2 (direction of arrow P), the large-diameter guide sprocket 8 at the lower end, the large-diameter guide sprocket 8 at the rear end of the first horizontal fabric passage 4b, 2nd horizontal fabric passage 4c
Small diameter guide sprocket 9 at front end, third horizontal fabric passage 4
d Wound in order around the large diameter guide sprocket 8 at the rear end, the small diameter guide sprocket 9 at the front end of the fourth horizontal fabric passage 4e, the small diameter guide sprocket 9 at the rear end of the fifth horizontal fabric passage 4f, and the small diameter guide sprockets 9, 9 on the outer circumference return side. It is passed around.

On the other hand, the second endless chain 3a is connected to the vertical fabric passage 4.
From the small-diameter driving sprocket 10 at the upper end of a, along the rotation direction (arrow Q direction), the small-diameter guide sprocket 11 at the lower end, the small-diameter guide sprocket 11 at the rear end of the first horizontal fabric passage 4b, and the front end of the second horizontal fabric passage 4c. arcuate chain guide (not shown), third horizontal fabric passage 4
d Small diameter guide sprocket at the rear end 11. It is sequentially wound around the arcuate chain guide (not shown) at the front end of the fourth horizontal fabric passage 4e and the small diameter guide sprocket 11 at the rear end of the fifth horizontal fabric passage 4f.

In addition, the driving sprocket 7.1 at the upper end of the vertical fabric passage 4a
0 are rotated at equal speeds in opposite directions by motor 12 via motor pulley 13, belt 14, drive pulley 15 and drive spur gear 16, 17, as shown in FIG.

Also, the lower end of the vertical fabric passage 4a, the first horizontal fabric passage 4b
The large-diameter guide sprocket 8 and the small-diameter guide sprocket 11 located at the rear end and the rear end of the third horizontal fabric passage 4d, respectively, are mounted on a rotatably supported spindle 18, as shown in FIG. ing.

However, one of the guide sprockets 8 and 11 is fixed, and the other is rotatably fitted.

In the above structure, when the fabric F is fed to the upper end of the vertical fabric passage 4a at a faster speed than the endless conveyors 2 and 3, the fabric F forms a wave shape in the space formed by the upper and lower fabric guide plates 5, 5. is housed in the endless conveyor 2,
3, the fabric moves down the vertical fabric path 4a, and is further sent upward while reciprocating back and forth along the horizontal fabric paths 4b to 4f, during which time it is subjected to liquid treatment and taken out.

At this time, since the fabric F is accommodated and transferred between the fabric guide plates 5 and 5 as described above, floating and meandering of the fabric F is suppressed, and there is no space between the fabric F and the endless conveyor 2.3. There is almost no slippage, so no wrinkles occur, and the amount of retention of the fabric does not change locally, so that uniform liquid treatment is performed.

Moreover, since the fabric passage 4 consists of the vertical fabric passage 4a and the horizontal fabric passages 4b to 4f, the installation area can be made smaller compared to the amount of fabric F retained.

In addition, in the above embodiment, the width of the first endless conveyor 2 is set wider than that of the second endless conveyor 3, so in the curved part where the first endless conveyor 2 rotates outside the second endless conveyor 3, These can be guided using two types of guide sprockets 8 and 11, large and small, which simplifies the guide mechanism.

In the above embodiment, the number of stages of the horizontal fabric passages 4b to 4f can be arbitrarily set to 3 or more, and especially when an odd number of stages is used, the limited volume of the liquid tank can be used without wasting the fabric. The retention amount can be further increased.

Further, the fabric guide plate 5 may be attached to the second endless conveyor 3.

Further, the fabric guide plate 5 is not limited to a rectangular flat plate, but may be a perforated plate.

As explained above, this invention consists of a fabric path formed by two sets of endless conveyors, one vertical fabric path, and three vertical fabric paths.
The machine consists of a horizontal fabric passage of tiers or more, and this fabric passage is finely divided by fabric guide plates attached to an endless conveyor, so that floating of the fabric is prevented and the fabric is processed uniformly. In addition to preventing build-up, the installation space can be saved compared to the amount of accumulation.
