Description

TECHNICAL FIELD The present invention relates to a blind cleaning method and device for cleaning a blind using a roll as a support.

[Prior Art] Conventionally, when cleaning a blind using a roll as a support, as shown in JP-A-60-153829, the curved surface of each slat (blade) of the blind is formed on the outer peripheral surface of the roll. Using a special roll that has a curved receiving surface that is aligned in the circumferential direction and is provided along the entire circumference, and the blinds to be cleaned are attached to the outer periphery of the special roll, with each slat closely supporting the curved receiving surface. As described above, the slat is wound around the entire length in a state of one turn, and in this state, the special roll is rotated to wash each slat by washing with a washing liquid or water.

According to such a blind cleaning method, the cleaning work can be performed while the blind is not supported by the worker but is supported by the roll.

[Problem to be Solved by the Invention] However, in such a conventional blind cleaning method using a roll as a support, a curved receiving surface that matches the curved surface of each slat of the blind is circumferentially provided on the outer peripheral surface of the roll. Since the special rolls provided by shifting the positions all over the circumference are used, there is a problem that the roll manufacturing cost becomes high.

Further, since the blind to be cleaned is wound around the outer circumference of the special roll in a state of one turn over the entire length so that each slat is in close contact with and supported by each curved die receiving surface, depending on the length of the blind. A roll having an outer diameter is required, and there is a problem that the roll becomes large depending on the length of the blind. Moreover, there is a problem that various special rolls having an outer diameter corresponding to the length of the blind must be prepared in advance. Further, when the blind to be cleaned is wound around the outer circumference of the special roll in a state of one turn over the entire length, it is necessary to position the slats individually so that they are closely supported by the curved receiving surfaces. There was a problem that workability was poor.

It is an object of the present invention to provide a blind cleaning method and device capable of efficiently cleaning the blind by using the same roll regardless of the length of the blind.

[Means for Solving the Problems] Means of the present invention for achieving the above object will be described.

The method for cleaning a blind according to claim (1) is such that the portion of the blind to be cleaned is along the outer periphery of the upper surface of the roll having a flat outer peripheral surface, and both ends of the blind are suspended from the upper surface of the roll to both sides. Adjacent slats to be cleaned of the blind are displaced in the width direction and arranged on the outer periphery of the upper surface of the roll, and the slats are cleaned in such a state.

The blind cleaning device according to claim (2) includes a liquid tank for accommodating a cleaning liquid and immersing the blind to be cleaned, and a blind cleaning device which is rotatably disposed above or inside the liquid tank. Should be placed along the outer periphery of the upper surface of the roll and both ends of the blind are hung from the upper surface of the roll on both sides, and the outer peripheral surface for supporting the adjacent slats to be cleaned of the blind by shifting the position in the width direction is flat. And a roll drive source that moves the portion of the blind to be cleaned by rotating the roll.

[Operation] As in the method for cleaning a blind according to claim (1), a portion of the blind to be cleaned is provided along the outer periphery of the upper surface of the roll having a flat outer peripheral surface, and both ends of the blind are disposed on both sides of the upper surface of the roll. The adjacent slats to be cleaned of the blinds are displaced in the width direction so as to be aligned with the outer periphery of the upper surface of the roll by cleaning the slats in such a state, and the same roll is irrespective of the length of the blind. Can be used to clean the blinds.

Further, if the blind is not wound around the outer periphery of the roll so as to make one turn, and is simply laid along the outer periphery of the upper surface of the roll and both ends are hung from the upper surface of the roll to both sides, the blind of the roll is wound regardless of the length of the blind. Can prevent upsizing.

Further, since the portion of the blind to be cleaned simply needs to be along the outer periphery of the upper surface of the roll having a flat outer peripheral surface, each slat is closely adhered to and supported by each curved receiving surface on the outer periphery of the roll. Thus, the work of individually positioning is unnecessary, and the workability can be improved.

Further, since the roll may have a flat outer peripheral surface, the structure of the roll is simplified and the manufacturing cost of the roll can be reduced.

When the blind cleaning device according to the second aspect has the liquid tank, the blind to be cleaned can be easily dipped in the cleaning liquid.

Further, when the blind is placed along the outer periphery of the upper surface of the roll and both ends of the blind are hung from the upper surface of the roll to both sides, adjacent slats are displaced in the width direction due to the action of the curvature of the roll and the action of the blind's own weight. By lining up the surfaces, cleaning of each slat can be easily performed.

Further, if the blind is not wound around the outer periphery of the roll so as to make one turn, and is simply laid along the outer periphery of the upper surface of the roll and both ends are hung from the upper surface of the roll to both sides, the blind of the roll is wound regardless of the length of the blind. Upsizing can be prevented, and upsizing of the device can be prevented.

Further, by supporting the blind with the roll, it is not necessary for an operator to always support the blind, and damage to each slat during cleaning can be prevented.

Further, by rotating the roll with the roll drive source, the portion of the blind to be cleaned can be easily moved.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings. As shown in FIGS. 1 to 4, the blind cleaning device of this embodiment has a liquid tank 3 in which a cleaning liquid 1 is contained and a blind 2 to be cleaned is immersed. The blind 2 has a structure in which each slat 2A is connected by a ladder tape. A heater (not shown) is provided in the liquid tank 3 so that the cleaning liquid 1 is heated to, for example, about 40 ° C.

Frames 4 are installed on both sides of the liquid tank 3 in the longitudinal direction, and the first and second rolls 7 and 8 are rotatably supported on the liquid tank 3 via bearings 5 and 6 on the frames 4. Has been done. These first and second rolls 7 and 8 have a flat outer surface. As such rolls 7 and 8, rolls having a diameter of about 40 mmφ are used.

These first and second rolls 7 and 8 are rotatably driven by first and second roll drive sources 9 and 10, which are, for example, brake motors. The rotational force of each roll drive source 9, 10 is the first composed of pulleys 11, 12, belts 13, 14 and pulleys 15, 16.
It is adapted to be transmitted to the rolls 7 and 8 by the first and second rotational force transmission mechanisms 17 and 18.

The blind 2 placed in the liquid tank 3 is left, for example, for about 1 to 3 hours to soften the dirt adhering to the surface of each slat 2A and weaken the binding force with the surface of each slat 2A. It should be noted that such an operation may be performed in a spare liquid tank.

Thereafter, the blind 2 is hung from one end side to the outer circumference of the upper surface of the first roll 7 so as to follow the outer circumference of the roll 7 and both ends of the blind 2 are hung from the upper surface of the roll to both sides. In this state, the first roll 7
The slat 2A of the blind 2 is displaced in the width direction on the outer periphery of the upper surface of the slat so that the slat surfaces are lined up so that the slat 2A does not overlap between adjacent ones as shown in FIG. Using this condition, the surface of each slat 2A is rubbed with a cloth or brush to remove dirt.

Next, when the operation switch 19 is pressed, the roll driving source 9 is rotated for a time set by a timer (not shown) and the first roll 7 is rotated by a predetermined angle, thereby moving the portion of the blind 2 to be cleaned. To be done.

In this way, the adjacent slats 2A in the portion to be cleaned next to the blind 2 are made not to overlap in the width direction, and the surfaces of these slats 2A are cleaned.

When the cleaning of each surface on one side of each slat 2A of the blind 2 is completed, the end portion of the blind 2 that was the terminal side in this cleaning operation is hung on the outer circumference of the upper surface of the second roll 8 and is attached to the outer circumference of the roll 8. Along and the blind 2
Both ends of the roll are hung from the upper surface of the roll 8 to both sides.

By doing so, the other surfaces of the slats 2A of the blind 2 which have not been cleaned yet are displaced in the width direction so that they do not overlap each other. The surface of is cleaned in the same manner.

Next, the operation switch 20 is pushed to rotate the second roll 8 by a predetermined angle, thereby moving the portion of the blind 2 to be cleaned, and similarly, the slats 2A are sequentially cleaned.

In this way, when the cleaning of the blind 2 is completed, the blind 2 is taken out of the liquid tank 3, washed with water and dried.

Although not shown, for example, a screw shaft and a guide shaft are erected on the first and second rolls 7 and 8, respectively, and screwed to each screw shaft and stopped by each guide shaft.
The blinds 2 can be automatically cleaned by supporting the first and second brushes on the first and second moving bodies and traversing the brushes left and right by the rotation of the screw shafts.

The first and second rolls 7 and 8 are immersed in the cleaning liquid 1,
Cleaning can be performed in the cleaning liquid 1 in the same manner.

The liquid tank 3 may be moved by a caster fixed to the lower surface of the liquid tank 3 without using the rail. Alternatively, the liquid tank 3 may be fixed and the frame 4 and the first and second rolls 7 and 8 may be movable.

Further, for example, if the width of the liquid tank 3 is made slightly larger, both the liquid tank 3 and the frame 4 may be fixed.

Alternatively, one roll may be provided, and the roll may be rotated in the normal direction to clean one surface of each slat, and then the reverse rotation may be performed to clean the other surface of each slat.
