Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is directed to a process in which belt-like fiber products such as endlessly connected woven fabrics, knitted fabrics, fiber bundle ropes, and tow-like fibers are placed in a liquid stream maintained at the flow rate of a processing liquid. The present invention relates to an apparatus for continuous processing under tension relaxation.

(Prior Art) Conventionally, in the textile industry, chemical treatments such as chemical treatments and dyeing treatments have been performed on belt-shaped textile products under no tension. Conventionally, such tensionless processing methods in a liquid include a method in which the strip-shaped fiber product is overfed using a feed roller and conveyed with sufficient relaxation in the processing tank, or a lattice feeder is installed in the processing tank. A method of conveying by lattice has been proposed.

(Problem to be Solved by the Invention) However, with the former method of overfeeding, not only is it not possible to achieve complete tensionlessness due to the tension caused by the delivery roller, but if sufficient relaxation is given, it may wind around the roller. Problems such as disarray and wrinkles in textile products have been pointed out. In addition, in the case of the latter type of lattice feeder, the weight of the textile product is added, creating frictional resistance between the textile product and the lattice, which not only prevents the textile product from loosening, but also causes problems such as disorder of the textile product and the occurrence of wrinkles. are doing.

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide an apparatus which overcomes these conventional problems and effectively and continuously processes textile products under complete relaxation.

(Means for Solving the Problems) That is, the present invention is a processing device for a strip-shaped fiber product that continuously processes a strip-shaped fiber product maintained at a flow rate of a treatment liquid under a relaxed state in a liquid flow. A supply roller that drops the belt-shaped textile product introduced into the chamber into a predetermined position, a shower pipe that injects a treatment liquid onto the textile product falling from the supply roller, and an overflow plate below the supply roller that connects the treatment chamber and drains the liquid. At the entrance of the processing chamber, the textile products falling from the supply roller are stacked in a folded manner and flowed into the processing chamber, and at the exit part, the textile products flow out to the drainage chamber at the flow rate of the processing liquid. A processing tank provided with a porous member to prevent outflow and an outlet for the processing liquid that overflowed the overflow plate into the drainage chamber, and a strip-shaped fiber treated in the processing tank above the outlet of the processing tank. This is a processing device for strip-shaped fiber products, which is equipped with a squeezing roller for dewatering the product.

(Function) According to the present invention, since the belt-shaped fiber product is accumulated in the processing chamber and tension-free processing is performed continuously, there is no winding of the belt-shaped fiber product around the roller or resistance due to the lattice, and sufficient It has the advantage of being able to provide relaxation and not causing any disturbance or wrinkles of the textile products in the treatment solution. Furthermore, since the device is compact and has few mechanical parts, there are fewer failures, and it can be operated automatically without requiring operator supervision.

(Embodiment) Next, an embodiment of the belt-shaped fiber product processing apparatus of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of the entire device, and FIG. 2 is a plan view.

The textile product 1 is adjusted to a predetermined tension by a tension adjustment device 2 such as a dancer roller provided at the entrance of the device, and then moistened in a washing tank 3 before being introduced into the processing device of the present invention.

In the processing device, the moistened textile product is reciprocated in the width direction by a traversing guide 4, then conveyed through a squeezing roller 5 to a supply roller 6 installed at a distance from the roller, and is transferred to a processing tank by the supply roller. fall inside. A shower pipe 7 is installed below the supply roller 6 to inject liquid onto the textile product to ensure that the textile product falls into the processing tank. Although this shower tube may be provided only on one side of the textile product, it is desirable to provide it on both sides of the textile product so that the liquid is sprayed downwardly on both sides of the textile product. A treatment tank A for chemically treating textile products is installed below the supply roller. This processing tank A has an overflow plate 10 and is divided into a processing chamber A1 and a drainage chamber A2.
A supply roller 6 is installed at the entrance of the processing chamber.
A shooter 8 is provided which loads the textile products 1 falling from the processing chamber in a folded manner and pours them into the processing chamber. The textile product 1 which is lowered into the processing chamber A1 in a pleated manner by the shooter 8 is conveyed through the bath evenly and without being subjected to large pressure loads, and is held under the processing liquid during this process. The textile product transported inside the processing chamber by the liquid flow of the processing liquid is led out from the outlet of the processing chamber, and is dehydrated by a squeezing roller 5 provided above the outlet of the processing tank A. At this time, it is desirable to provide a porous member 9 at the outlet of the processing chamber to prevent the textile products from flowing out together with the processing liquid overflowing the overflow plate 10 into the drainage chamber. As such a porous member 9, a plastic net or the like is usually preferably used. The textile products taken out from the processing chamber are passed through a plurality of liquid draining guides 11 alternately to drain the liquid before being dehydrated by the liquid squeezing roller 5. When further chemical treatment or cleaning treatment is performed on the textile products taken out from the first treatment tank A, the textile products whose liquid has been drained by the liquid draining guide 11 are reciprocated in the width direction by the traversing guide 4, and then The processing liquid, in which the textile products have been transferred into the processing liquid flow flowing through the processing chamber A1, is dehydrated by the liquid squeezing roller 5 and led to the second processing tank B, overflowing the overflow plate 10 and flowing into the liquid drainage chamber A2. flows into. The treated liquid that has flowed into the drain chamber A2 is returned to the treated liquid tank (not shown), where the chemical components are adjusted again, and then sent to the shower pipe 7 by a circulation pump (not shown). . In order to increase the flow rate of the circulating liquid and improve the processing effect, a shower box 12 with a large number of holes is provided at the top of the processing chamber, and the processing liquid is transferred from the shower box into the processing chamber. It may also be allowed to flow down from the top.

In FIG. 1, the water is moistened in the first treatment tank A, and the second
An example is shown in which a textile product chemically treated in the third treatment tank B is washed in the third treatment tank C. In addition, each treatment tank has a sealed structure to prevent the chemicals from scattering around and to prevent bad odors. If it is only for cleaning, it is not necessary to have a sealed structure. The textile product 1 drawn out from the third treatment tank C is sent to the next process such as drying. Therefore, the traversing guide provided at the outlet portions of the first and second processing tanks is not required at the outlet of the third processing tank. If the textile product is a wide fabric, etc., instead of the traverse guide shown in FIG. 1, a twill plate 20 provided at the inlet of the treated moisture can be used to traverse in the direction of the arrow as shown in FIG. 3. The textile products 1 falling from the supply rollers 6 supported by the fibers 1 can be piled up in a pleated manner and flowed down into the processing chamber.

At the outlet of the processing chamber, a plurality of phototubes 15 are provided on the side wall of the processing tank. This phototube does not operate when textile products are normally accumulated in the processing chamber, but if textile products accumulate abnormally up to the exit of the processing chamber and the optical path of all phototubes is blocked,
Sends an accumulation abnormality signal. In this case, in order to eliminate malfunctions, an abnormality signal is sent only when all phototubes are activated. When the drive circuit for the squeezing roller 5 receives this signal, it increases the rotational speed of the roller to speed up the removal of the textile product from the processing chamber. When the rotational speed is increased for a certain period of time, the rotational speed of the roller returns to the normal rotational speed. At this time, if the accumulation is not sufficiently eliminated, a accumulation abnormality signal is sent again, and the rotational speed of the roller is increased until the accumulation reaches a normal amount.

(Effects of the Invention) As described above, in the apparatus of the present invention, the textile products are continuously processed without tension in the processing tank, so that the winding of the textile products around the rollers and the resistance due to the lattice, which is conventional, is eliminated. It is possible to provide sufficient relaxation without any stress, and chemical treatment can be carried out efficiently. In addition, the processing device is extremely compact and has few driving parts, so it is a device that is less likely to break down.
