Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind cleaning device.

[0002]

2. Description of the Related Art A blind is a flexible ribbon-like thin blade piece connected by a string and is difficult to handle by a machine. Depended solely on human resources. That is, a dirty blind was spread over the soil, and while washing water was applied, it was manually rubbed with a scrubbing brush, a brush, a mop, and the like.

[0003]

Therefore, in the prior art,
Many man-hours were required for cleaning the blinds. The present invention provides a cleaning device that enables the automatic cleaning of the blinds described above, thereby significantly reducing the number of steps for cleaning the blinds.

[0004]

SUMMARY OF THE INVENTION A blind cleaning device according to the present invention comprises a blind feeding means for intermittently feeding the blind in its length direction, and a width direction in which the blind is sandwiched while the blind is stopped. A pair of rotating brush rollers that move to the front and rear, and a rotatable front nip roller and a rear nip roller that sandwich the blinds in front of and behind the rotating brush roller and that move together with the rotating brush roller.

The blind cleaning device can be formed so that the blind is fed in a horizontal direction and a pair of rotating brush rollers are vertically opposed to each other and move horizontally. Then, the support belt, which is in contact with the lower surface of the blind and is orthogonal to the length direction of the blind, and has both ends fixed, is wound around the nip rollers before and after the lower rotating brush roller to surround the lower half portion of the lower brush roller. It can be stretched to bend in a U shape. It is preferable that the brush of the rotating brush roller is formed of a synthetic resin line, and it is particularly preferable that the tip of the line is divided into a plurality of lines.

[0006]

When the blind is stopped, the pair of rotating brush rollers sandwiching the blind move in the width direction of the blind together with the nip rollers before and after the blind, so that the blind is held by the nip roller in front of and behind the rotating brush roller. Then both the front and back sides are rubbed with a rotating brush roller. Therefore, stains on the blinds are washed off by applying washing water to the rotary brush roller and the blinds. Then, after the rotary brush roller and the nip rollers before and after the rotary brush pass through the blind in one direction, the blind is advanced by a predetermined length, and then the rotary brush roller and the nip roller are retracted to wash the blind in the same manner. . The blind may be fed forward after the rotating brush roller and the nip roller make one reciprocation.

However, since the bristle tips of the rotating brush roller rotate along the width direction of the blind, that is, the length direction of a large number of blade pieces forming the blind, the thin blade pieces are not damaged. . In particular, when the bristles of the brush are formed of synthetic resin filaments and the tip portion of the filaments is divided into a plurality of filaments, the contact with the blade pieces becomes soft and damage is further reduced.

Further, when the support belt contacting the lower surface of the blind is stretched as described above, since the deflection of the blind is prevented, the nipping of the blind by the nip roller is easy and it is not necessary to tension the blind strongly. Therefore, there is no risk of cutting the blind connecting string. Moreover, at the portion where the rotating brush roller is located, the support belt retracts from the contact portion of the upper and lower rotating brush rollers to one side of the rotating brush roller, so that it is possible to wash both the front and back surfaces of the blind without any trouble.

[0022]

As described above, the blind cleaning device according to the present invention has the blind feeding means for intermittently feeding the blind in the lengthwise direction and the widthwise direction with the blind sandwiched while the blind is stopped. Since a pair of rotating brush rollers that move to the front and rear, and a rotatable front nip roller and a rear nip roller that move together with the rotating brush roller sandwiching the blind between the rotating brush roller and the rotating brush roller are provided, a long blind is provided. The rotary brush roller can be reciprocated in the width direction of the blind while feeding in the length direction to clean both the front and back surfaces of the blind. Then, while the blind is held by the nip roller in front of and behind the rotating brush roller, the front and back surfaces of the blind are rubbed by the rotating brush roller to remove stains from the blind. Does not hurt.

According to the second aspect of the invention, the blind is fed in the horizontal direction, the lower surface thereof is supported by the supporting belt, and the supporting belt is located below the lower rotating brush roller between the lower front and rear nip rollers. Therefore, even when the blind is fed horizontally, the front and back surfaces of the blind are completely exposed and cleaned without bending the blind downward. Further, in the invention described in claim 3, since the brush of the rotary brush roller is formed by the line of synthetic resin and the tip of one line is divided into a plurality of lines, the rotation of the blind blade with respect to the blade piece is prevented. The contact of the brush roller can be made softer.
