Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cloth cleaning device in which a long cloth is placed on a conveyor in a corrugated plate shape and fed forward, and a cleaning liquid is sprayed from above and below to wash the cloth. is there.

[0002]

2. Description of the Related Art As a cloth cleaning apparatus, as shown in FIG. 7, a cloth F in a spread state is over-fed and supplied onto a perforated conveyor 3 stretched between front and rear sprockets 1, 2.
It is known that the cloth F is placed and transferred so as to form a large number of folds in the width direction, and the cleaning liquid W is sprayed from the cleaning liquid spray pipes 4 and 5 arranged in a zigzag pattern in two rows above and below the cloth F. There is.

[0003]

However, in the above apparatus, the overfeed rate of the cloth F can be increased and a large amount of cloth F can be placed on the perforated conveyor 3 to wash a large quantity of cloth F. As compared with the upper and lower folds (folds) of the fabric F stacked on the multi-pass conveyor 3, the cleaning liquid is less likely to be applied to the inner linear portions, and the folds formed at the beginning hardly move, so that the cleaning unevenness is small. And the cleaning liquid W is sprayed directly or through the holes of the multi-pass conveyor to the fabric F on the multi-pass conveyor.
The rubbing effect and the hitting effect given to the fabric F were small, and the texture was not sufficiently improved.

The present invention is a cleaning apparatus of the type in which a cleaning liquid is sprayed while over-feeding and transferring a spread cloth on a conveyor, and the cloth is sufficiently cleaned even if the cloth volume is increased. In addition, it is possible to improve the texture of the fabric by adding a rubbing effect and a hitting effect.

[0005]

A cloth cleaning apparatus according to the present invention supplies a spread cloth at a predetermined overfeed rate onto a horizontally running multi-pass conveyor, and the cloth is
In a cloth cleaning device in which a cleaning liquid is sprayed from a plurality of spray pipes arranged in a zigzag pattern in two rows above and below with the transport surface of the multi-hole conveyor interposed therebetween, the cleaning liquid sprayed from the lower spray pipe. Is set to be larger than the pressure of the cleaning liquid sprayed from the upper injection pipe, and the direction of the cleaning liquid that is sprayed from the lower injection pipe and rises up through the porous conveyor above the perforated conveyor is fed to the perforated conveyor. A deflecting device for changing the direction is provided.

The cleaning liquid pressure in the upper injection pipe is 0.
5 to 1.0 kg / cm ² and the cleaning liquid pressure in the lower injection pipe are preferably 0.5 to 3.0 kg / cm ² . However, the cleaning liquid pressure on the lower side is higher than the cleaning liquid pressure on the upper side, and is set high enough to push the cloth above the injection pipe 200 to 600 mm above the conveyor by the cleaning liquid injected from the lower injection pipe. Further, the above-mentioned deflecting device may be any device as long as it can change the direction of the cleaning liquid jetted upward from the lower jet pipe to the feeding direction of the multi-hole conveyor, and is a baffle plate inclined about 45 degrees with respect to the horizontal plane. ,
When viewed from the side of the multi-pass conveyor, the current plate is curved in an arc shape that is convex upward, or rotates around the width-direction axis from the delay side to the advance side through the bottom of the width-direction axis with respect to the running direction of the multi-pass conveyor. A wing-shaped beater or the like can be used. Instead of providing this deflecting device, the perforated conveyor can be formed by alternately connecting perforated plates and flat plates without holes between a pair of left and right endless chains.

[0007]

In the same manner as in the conventional case, the fabric is placed on the perforated conveyor and fed forward while forming a fold in the width direction. Then, when the above cloth passes under the upper injection pipe, the cleaning liquid injected from the injection pipe is poured from above to be washed in substantially the same manner as the conventional one and pressed onto the multi-pass conveyor. on the other hand,
When the above-mentioned cloth passes above the lower jet pipe, the above-mentioned cloth is pushed upward by the high-pressure cleaning liquid jetted from the lower jet pipe, and then in the feeding direction of the multi-pass conveyor. The above-mentioned cloth is blown in the feeding direction by the cleaning liquid whose direction is changed, and then the cloth is struck and folded on the multi-hole conveyor and folded again. However, the pleats at this time are often formed at a position different from the place where the first pleats were formed. Therefore,
The cleaning effect is improved, the uneven cleaning is eliminated by repeatedly receiving the action of the deflecting device, and the hitting and rubbing effects are added, and the texture is improved.

However, in the case of using a perforated conveyor in which perforated plates and flat plates without holes are alternately arranged instead of providing the above-mentioned deflecting device, when the perforated plate passes above the lower injection pipe, the perforated plate is placed on the perforated plate. Of the cloth is lifted high by the cleaning liquid for the lower injection pipe, and along with this, the cloth on the flat plate before and after the perforated plate is also lifted, the first pleats of these cloths are stretched, and the perforated plate is moved to the lower injection pipe. After passing above, the above-mentioned cloth falls on the original perforated plate or flat plate, is folded up again by this fall, folds are formed at a position different from the initial position, and is transferred. That is, the cloth is washed while repeatedly rising and falling with respect to the conveying surface of the multi-pass conveyor. Therefore, the cleaning effect of the cloth is improved, and the rubbing effect and the hitting effect are provided.
