Description

[Detailed description of the invention] (Industrial application field) This invention relates to a washing device for continuously washing a long piece of fabric while transporting it in an expanded form, and is used for the fabric dyeing process, desizing, scouring, etc. Used in various processing steps.

(Prior art) A fabric cleaning device was developed in Jitsukasho that was designed to continuously wash long fabrics while conveying them in an expanded form.
Publication No. 57-116797 discloses a horizontal running water washer in which the fabric is guided from the bottom to the top in a zigzag pattern while reciprocating back and forth, and during this time the cleaning liquid flows down from the top to the bottom for cleaning. . That is,
A large number of large-diameter guide rollers are arranged vertically in the casing in a zigzag pattern in two rows, front and back, and cleaning liquid can be stored below each of these large-diameter guide rollers. A liquid collection gutter is provided in which the lower part of the guide roller is immersed, and the large diameter guide roller guides the spread fabric upward in a zigzag pattern while reciprocating back and forth from the lower part of the casing 1 to near the top stage. The cleaning liquid is sprayed from a nozzle onto the fabric hanging on the large-diameter guide roller, part of this cleaning liquid is transferred upward with the fabric, and the rest is sequentially flowed downward to wash the fabric. It is compressed by a squeezing roller located above the large-diameter guide roller in the upper stage and sent upward.

(Problem to be solved by the invention) Conventionally, a nozzle for supplying cleaning liquid was provided only above the large-diameter guide roller at or below the top stage, and the cleaning liquid was sprayed onto the fabric hanging on the large-diameter guide roller. However, since the fabric was washed by flowing this washing liquid down in sequence, lint, fiber waste, and other impurities tend to accumulate at the bottom of the liquid collection gutter located below each of the many large-diameter guide rollers. To remove it, workers had to enter the casing and tilt or remove the collection gutter. In particular, when washing is performed following the desizing process or scouring process after burning, a lot of fuzz and sizing agent fall off from the fabric, which increases the number of times the liquid collection gutter needs to be cleaned and the number of cleaning workers required. In addition to this, the operating rate of the cleaning equipment was significantly reduced.

This idea allows you to wash the fabric without having to stop washing it.
To provide a fabric cleaning device capable of cleaning a liquid collection gutter.

It flows together with W from the overflow port 3c and flows down onto the fabric F below. Therefore, the cleaning liquid injection nozzle 11 is provided for each liquid collection gutter 3, and the on-off valve 10a of the branch pipe 10 is provided for each cleaning liquid injection nozzle 11, so the on-off valve 10a can be opened individually. , the liquid collection gutter 3 can be cleaned one by one. For example, an electromagnetic on-off valve is used as the on-off valve 10a, and these electromagnetic on-off valves 1
The liquid collecting gutter 3 can be cleaned periodically by automatically opening and closing the cleaning liquid gutter 0a and opening a large number of cleaning liquid spray nozzles 11 sequentially from the top one and for short periods of time.

(Example) In Fig. 1, 1 is a casing, 2 is a large-diameter guide roller, and 3 is a liquid collection gutter. The cleaning liquid W is spouted from the nozzle 4 of
This cleaning liquid W is sequentially flowed downward to clean the fabric F.
The fabric F is then sent upward from an upper squeezing roller 5.

As shown in FIG. 2, the front row liquid collection gutter 3 includes a main body portion 3a that covers the front lower part of the large-diameter guide roller 2 in an arc shape and is slightly inclined upward at the rear, and this main body portion 3a.
It consists of an auxiliary gutter 3b connected to the rear end, and an overflow port 3c is provided at the rear edge of the auxiliary gutter 3b, so that the lower part of the large diameter guide roller 2 is immersed in the cleaning liquid W stored in the main body part 3a. , the cleaning liquid W is applied to the main body part 3a.
It overflows from the trailing edge and flows into the auxiliary gutter 3b, and further overflows from the overflow port 3c and flows down onto the fabric F below. An intermediate guide roller 6 for bending the fabric F into a chevron shape is provided slightly behind the large-diameter guide roller 2, and a guide bar 6 is provided below the overflow opening 3c so as to be in contact with the lower surface of the fabric F passing through this portion. 7 is provided in the width direction. In addition,
The liquid collection gutter 3 in the rear row is formed symmetrically with the liquid collection gutter 3 in the front row shown in FIG. 2 above.

In FIG. 1, the cleaning nozzle 4 above the large-diameter guide roller 2 located at the top of the front row is fixed to the tip of a first branch pipe 9 branching from the cleaning liquid supply pipe 8. A cleaning liquid spray nozzle 11 (see FIG. 2) is fixed to each of the tips of four second branch pipes 10 branching from the pipe 9, and the cleaning liquid spray nozzle 11 is provided downward slightly behind the large diameter guide roller 2. It is being An on-off valve 8a and a heater 12 are interposed in the cleaning liquid supply pipe 8, and a steam pipe 13 equipped with an on-off valve 13a is connected to the heater 12 so that the cleaning liquid is heated when it passes through the heater 12.
