Description

The present invention relates to cleaning apparatus and a cleaning method suitable for the cleaning of the blind having been that exhibition ductility over the window of the building.

A blind attached to a building window for shading can adjust the amount of shading by hanging a plurality of slats called slats so that they can be raised and lowered at a predetermined interval and adjusting the inclination angle of the slats. It is like that. Blinds become dirty due to dust accumulation on the slats after long-term use. As apparatuses for cleaning such a blind blind, cleaning apparatuses described in Patent Documents 1 and 2 below have been proposed.

  The cleaning device described in Patent Document 1 is a cleaning device that uses vibration energy by ultrasonic waves. However, in the case of a cleaning apparatus using ultrasonic waves, dirt may remain on the blinds only by ultrasonic cleaning in a cleaning liquid mixed with a detergent. For this reason, inspection by visual inspection is eventually performed, and if dirt remains, it is necessary to manually wash the portion with a bundler or a sponge, and there is room for improvement in terms of work efficiency.

In addition, the cleaning device disclosed in Patent Document 2 is a cleaning device that scrubs the slats of the blinds with a brush, but when scrubbing with a brush, the end of the slats is raised to damage the blinds. There was a fear.

Therefore, in view of the above circumstances, an object of the present invention is to provide a cleaning device that has high working efficiency and can be cleaned without damaging the blinds .

To solve the problems described above, in the cleaning device according to the invention has a pair of brush roller to scrub the blind, the pair of brush rollers are rotated in opposite directions to each other, moreover, spread On the premise that cleaning of the blind by the brush roller starts from a state in which the pair of brush rollers are in contact with the surface of the blind, the lower part on the work table side in contact with the blind rotates in a direction away from each other.

Because of this characteristic, in the cleaning device according to the present invention, the blinds are cleaned without damaging the blinds by cleaning the pair of brush rollers always in contact with the blinds. Can do.

That is, since the pair of brush rollers rotate in opposite directions, the forces received by the blinds due to the friction with the brush rollers are balanced and cancel each other. For this reason, the movement of the blind during washing | cleaning can be suppressed.
Furthermore, when cleaning the ends of the blind, the brush portion of the brush roller is to scrubbing to stroke down the ends of the blind on the outside, since no increase Ri sow end of the blind, the blind Can be cleaned without damage.

  An embodiment of a cleaning device according to the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view showing an embodiment of a cleaning device according to the present invention, FIG. 2 is a perspective view showing a brush roller for scrubbing a blind , its rotation driving device and a feed (moving) mechanism, and FIG. 3 according to the present invention. FIG. 4 is a longitudinal sectional view schematically showing the cleaning device, FIG. 4 is a view showing the relationship between the brush roller and the blind of the cleaning device according to the present invention, and FIG. 5 is a perspective view showing a stopper used together with the cleaning device.

As shown in FIG. 1, the cleaning apparatus according to the present invention includes a work table 2 on which a blind 1 is placed and extended. The work table 2 is formed by bending a stainless punching metal and has a flat portion 2a having a flat upper surface and vertical side portions 2b on both sides, and the flat portion 2a and the side portions 2b on both sides are smooth. The curved surfaces 2c are connected to each other, and the cross section is formed into a substantially bowl shape. The work table 2 carries the extended portion of the blind 1 on the upper surface of the flat portion 2a. On both sides of the work table 2, a pair of cleaning tanks 5 and 6 for storing the cleaning liquid 3 with the work table 2 interposed therebetween are arranged. The cleaning tanks 5 and 6 are arranged vertically below the flat portion 2a, and the cleaning tanks are connected to the cleaning tanks 5 and 6 through communication pipes 7 (see FIG. 3) so that the water levels of the cleaning liquid stored in the cleaning tanks 5 and 6 are equal. Are connected to each other.

  Since the dimensions in the longitudinal direction of the work table 2 and the cleaning tanks 5 and 6 are set to be slightly larger than the width dimension of the commercially available maximum width blind, all the commercially available blinds can be accommodated. That is, if it is a commercially available blind, it can be stored in the cleaning tank 5 and immersed in the cleaning liquid, and can be spread on the flat portion 2 a without protruding in the longitudinal direction of the work table 2. it can.

  A rinsing tank 8 is provided outside the cleaning tank 6. The rinsing tank 8 is formed in a size that can accommodate a commercially available blind of the maximum width, similar to the cleaning tanks 5 and 6. The cleaning tanks 5 and 6 and the rinsing tank 8 are provided with pipes (not shown) for supplying fresh water such as tap water, and are provided with drainage outlets as shown in FIG. A stop cock 10 is attached to each mouth.

  An air pipe 12 is submerged in the cleaning tanks 5 and 6 and the rinsing tank 8. A plurality of ventilation holes for releasing air are formed in the side surface of the air pipe 12, and compressed air is supplied from a compressor (not shown). Therefore, when the compressor is operated, air is discharged from the air pipe through the vent hole into the cleaning liquid or the rinsing water, and the convection of the cleaning liquid 3 and the rinsing water can be promoted.

A pair of brush rollers 13 is provided above the work table 2. As the brush roller 13, an outer diameter of 90 mm, a brush hair length of 30 mm, a brush hair thickness of 0.132 mm, and a brush hair material of nylon were used. The brush roller 13 is rotationally driven by a rotational driving means for rotationally driving the brush roller 13. The rotation driving means can be constituted by a power source such as a motor 16 provided with a speed reducer 15 and a power transmission member such as a pulley 17 and a belt 18. As shown in FIG. 1 or FIG. 2, by using a belt wound around a pulley attached to one brush roller as a hook, the brush rollers are driven to rotate in opposite directions. .
The brush roller 13 is provided so as to be able to move in parallel along the upper surface of the flat portion 2a of the work table in a direction perpendicular to the rotation axis thereof and in a direction perpendicular to the direction connecting the pair of cleaning tanks 5 and 6. .

  In the illustrated embodiment, the brush roller 13 and the rotation driving means are mounted on a movable table 20 provided so as to straddle the work table 2 and movable in parallel with the longitudinal direction of the work table. A wheel 22 that rolls on a rail 21 provided near the outer lower ends of the washing tank 5 and the rinsing tank 8 is rotatably attached to the movable table 20, and the movable table reciprocates along the rail 21. It comes to move.

  A rack gear 23 is provided on the lower side of the rail 21 and meshes with a pinion gear 25 that is rotatably attached to the movable table. A manual handle 26 is rotatably attached to the movable base 20, and the rotation of the manual handle 26 is transmitted to the pinion gear 25 via the sprocket 27 and the chain 28. Therefore, the brush roller 13 can be freely moved in the longitudinal direction of the work table 2 by rotating the handle 26.

The movable table 20 is equipped with a cleaning liquid spraying means for spraying the cleaning liquid 3 onto the blind 1 and the brush roller 13 extended on the work table flat portion 2 a, and supplies the cleaning liquid to the contact portion between the blind 1 and the brush roller 13. The scrubbing with the brush roller can be performed smoothly. The cleaning liquid spraying means includes an electric pump 30 that pumps the cleaning liquid from the cleaning tank 5, a nozzle pipe 31 that is provided in parallel with the rotation center axis of the brush roller, and a pipe 32 that connects these. The nozzle pipe 31 is a pipe in which a plurality of holes are opened toward the spraying direction of the cleaning liquid.

Further, the movable table 20 is provided with a height adjusting mechanism 34 for adjusting the height of the brush roller 13 with respect to the flat part of the work table, and the height of the brush roller 13 is adjusted when the brush becomes worn or shortened. It can be adjusted. Specifically, the movable base 20 is composed of a movable base upper part and a movable base lower part, and after the bolts and nuts that fasten the upper part and the lower part are loosened, the movable base 20 can be moved up and down relatively. The height of the upper part of the movable table can be adjusted by turning the bolt for adjusting the height of the upper part of the movable table. In this way, the brush roller 13 can scrub the blind 1 with appropriate strength.
All the mechanisms described above are supported by the base 33 as shown.

It is desirable that a large number of through holes are formed in the flat portion 2 a of the work table 2. If a through-hole is formed on the flat part, excess cleaning liquid adhering to the spread blind 1 quickly flows down from the through-hole, so that the slats attached to each other by the surface tension and viscosity of the cleaning liquid are attached. This is because it is easy to separate the pieces on the flat portion.

And when providing a through-hole in the flat part 2a, the washing | cleaning-liquid induction | guidance | derivation board 35 is inclined and provided in the vertically downward direction of the flat part. The cleaning liquid guide plate 35 receives the cleaning liquid flowing from the flat portion through the through hole and guides it to the cleaning tank 5, and enables the circulation and reuse of the cleaning liquid.
Even when the flat portion 2a is not provided with a through-hole, the excess cleaning liquid flows down to the cleaning tank along the side surface of the work table, so that the cleaning liquid can be circulated and reused.

  In order to suppress the occurrence of rust, the work table 2 is desirably made of stainless steel, and it is desirable to use so-called punching metal in view of providing a large number of through holes in the flat portion as described above.

When using stainless steel as the material of the working table 2 as described above, the slats of a blind 1 and worktable 2 are attached stainless metal component to the contact portion of the direct contact with rubbing the blades, blade plate Problem arises. Therefore, in order to solve this problem, it is desirable to apply a contact prevention treatment for preventing the stainless steel work table and the blind 1 from coming into direct contact with each other by attaching a resin film such as polyethylene on the upper surface of the work table. This contact prevention treatment can be performed by coating the surface of the work table with a fluororesin in addition to attaching the resin film to the work table.

When the above-described contact prevention treatment is performed on the work table 2, it is desirable to select a material that can make the friction resistance with the blind slats smaller than the friction resistance of the work table made of stainless steel. Examples of such a material include the above-described polyethylene film and fluorine-based resin film. In this way, when a material having a lower frictional resistance than stainless steel is used, the blind slats are used when the blind 1 immersed in the cleaning liquid 3 is pulled up from the cleaning tank 5 onto the flat part 2a of the work table and extended. Is preferable because the frictional resistance is reduced and the operation is facilitated.

  On the other hand, as shown in FIG. 4, when one brush roller is removed from the end of the blind slat 36 when the brush roller is cleaned, the slat is received from the other brush roller by the amount of reduced frictional resistance. It becomes easy to move to the other end side (in the direction of arrow 37 in the figure) due to the frictional force. In this case, in order to prevent the movement of the slat 36, it is desirable to stop the opposite end of the slat with a stopper 38.

  For example, as shown in FIG. 5, the stopper 38 can be obtained by integrally forming a pair of protrusions 38b on the lower surface of the elongated plate-like member 38a, and the pair of protrusions 38b are formed on the worktable flat portion 2a. The movement in the horizontal direction is regulated by being inserted into the through hole.

  Next, a procedure for cleaning the blind using the above-described cleaning apparatus will be described in order.

First, the blind 1 is immersed in the cleaning liquid 3 in the cleaning tank 5, and the cleaning liquid is spread over the surface of the blind slats. Next, the blind 1 is pulled up from the cleaning tank and spread from the upper end portion of the blind to the flat portion 2a of the work table. At this time, since the side surface portion 2b and the flat portion 2a of the work table are connected by the smooth curved surface 2c, the blind 1 is slid along the surface of the work table 2 and smoothly spread on the flat portion 2a. be able to.

Since the slats of the blind 1 may stick to each other due to the viscosity or surface tension of the cleaning liquid, after manually rubbing them on the flat part, the manual handle 26 is rotated to move the movable base 20. Then, the pair of brush rollers 13 is moved on the blind extended on the flat portion 2a. Then, after confirming that both of the brush rollers are in contact with the surface of the blind slats, the cleaning liquid spraying means is operated, and the electric motor 16 is driven to rotate the brush roller 13 to start cleaning. Then, the manual handle 26 is further operated to move the brush roller from end to end of the vane so as to clean the vane.

  When cleaning the end of the slats, as shown in FIG. 4, the pair of brush rollers both scrub the slats (the slats 36 are indicated by chain lines) from the outer side. There is no problem that the brush roller passes through the end of the slat and is not in contact with the slat (the slat 36 is indicated by a solid line). However, if the brush roller on the center side of the blind scrubs the end of the slat, there is a risk that the end of the slat will be scooped up. Therefore, it is necessary to control the movement of the brush roller so that the brush roller located on the center side of the blind does not hit the end of the blade.

  When the cleaning of the slats spread on the flat portion 2a is completed, the rotation of the brush roller is stopped and the operation of the cleaning liquid spraying means is stopped, and the movable base 20 is temporarily moved from the top of the blind to the standby position (the frontmost position in FIG. 1). Position). And an unwashed slat is spread on the flat part 2a, and the above-mentioned operation is repeated.

  When the cleaning operation is completed, the blind is transferred from the cleaning tank to the rinsing tank, and the cleaning liquid is rinsed off. The rinsing may be performed by rinsing with fresh water stored in a rinsing tank or by rinsing with running water while flowing fresh water. When rinsing is completed, the work is completed by drying the blinds in a well-ventilated shade.

  The cleaning liquid used in the above description was a 1% solution obtained by diluting a detergent called Adeka Cleaner Off manufactured by ADEKA Clean Aid Co., Ltd. with tap water. Although the cleaning liquid has sufficient cleaning power even at room temperature, if the ambient temperature decreases, such as in winter, the temperature of the cleaning liquid should be kept at 20 ° C or higher by submerging a heater for heating in the cleaning liquid in the cleaning tank. It is desirable.

  The cleaning device according to the present invention has applicability in the machine industry in terms of manufacture, and has applicability in the service industry of cleaning in terms of use.
