2 and guide rollers 13 from the bottom to the top, washing water W is sprayed from the nozzle on the upper part of the casing, and the washing water W accumulated in the washing tank 10 is made to flow down from the overflow wall 11 to the outer guide rollers below. It has been proposed that the space between the front and rear surfaces of the casing be narrowed and that the front and rear surfaces be provided with work doors, respectively.
No. -102316 [Actual Kaihei 5-45087] and Japanese Utility Model Application 4-87672 [Actual Kaihei 6-428989].

However, the washing tank 10 of the above-mentioned prior invention
Since the left and right side walls are fixed to the inner surface of the side wall of the casing by brackets and bolts and nuts, in order to clean the water tank 10, the work door on the front surface or the rear surface of the casing is opened. Mounting bolts
It is necessary to remove the nut and take out the washing tank 10 together with the two immersion rollers 12 from the front or rear opening of the casing to the outside. In this case, the inner surface of the washing tank 10 and the overflow wall 11 must be removed.
Since the gap between the immersion roller 12 and the immersion roller 12 is narrow, it is difficult to clean, and the rising portions of the overflow wall 11 and the front, rear, left, and right inner walls in the washing tank 10 are angular, and the washing water W hardly flows. It was difficult to remove the thread wastes, cotton wastes, and the like that had fallen off the fabric F from these portions, and to remove them easily. After the cleaning is completed, the washing tank 10 is again fixed to the inner surface of the casing with the bolts and nuts. Therefore, the immersion roller 12 needs to be centered.
Had a problem of meandering and wrinkling.

This invention facilitates cleaning of the washing tank 10 without lowering the cleaning effect of the above-mentioned prior invention, eliminates the need for centering the immersion roller 12 after cleaning, and reduces the time required for stopping the cleaning. It is designed to save a lot of money.

SUMMARY OF THE INVENTION A cloth washing apparatus according to the present invention comprises a pair of front and rear washings each comprising a washing tank and a dipping roller in a vertical casing having working openings formed in a front plate and a rear plate, respectively. The units are arranged in multiple stages in the vertical direction and so that a pair of front and rear washing tanks in each stage are close to each other so that they do not interfere with each other, and the long fabric introduced to the front surface of this casing is reciprocated back and forth from the lower front side. While being guided in a zigzag form from bottom to top while being dipped in the above washing tank in order, the washing water is allowed to flow downward from the upper part of the casing in order, and the fabric is drawn out from the upper rear surface of the casing. It is a water washing device, and each of the water washing tanks is formed so as to be vertically swingable with its front end or rear end as a fulcrum, and an elevating device consisting of a fluid cylinder is connected to the water washing tanks so that Immersion roller position unchanged near the bottom of the washing tank by the operation of the descending device is characterized by being reciprocally formed between a downwardly inclined position, which can be discharged a horizontal position and intracisternal liquid located. In addition, it is preferable to form an overflow port on the wall surface of the facing portion of the pair of front and rear washing tanks in each stage.

[0008]

The cloth introduced into the front surface of the casing moves upward and backward in a zigzag manner while reciprocating from the lower front side in the casing forward and backward, while the cloth is immersed in the horizontal washing tank in the pair of front and rear washing units at each stage. And is washed with washing water that flows down from the top, and is drawn out from the upper rear surface of the casing. When cleaning the washing tank, the lifting device is operated to move the washing tank rapidly to the downward inclined position, so that the washing water in the washing tank flows out vigorously. The thread waste and cotton waste, etc., are easily discharged. In this case, since only one dipping roller is immersed in one washing tank,
It is easy to form the bottom surface of the washing tank into a smooth cylindrical surface, which makes it easier to discharge thread waste, cotton waste, and the like. Then, after the cleaning is completed, when the elevating device is actuated again and the respective washing tanks are returned to the horizontal position, the immersion roller is not removed at the time of the cleaning, and therefore, the core of the immersion roller is readjusted when the operation is restarted. There is no need, and the operation can be restarted immediately after returning the flush tank to the horizontal position.
