Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an adhesive roll for a cleaning tool.

[0002]

2. Description of the Related Art As a cleaning tool, there is a cleaning tool which has a brush body and an adhesive roll independently of each other and collects dust by each of them (Shokai Sho 59-139261). When cleaning with the adhesive roll, the adhesive roll is brought into direct contact with the carpet or flooring to rotate it.

[0003]

The above prior art has the following problems. The adhesive roll consists of a core with a diameter of about 38 mm and an adhesive sheet wound around it. The initial outer diameter is as large as about 60 mm, and the cleaning tool cannot be made compact. Since the adhesive roll comes into direct contact with the surface to be cleaned, not only dust but also the flocked hair of carpets, etc. will adhere to the surface of the adhesive roll, and if the surface area of the adhesive roll is not large, the adhesive force will weaken immediately. Since the floor area (cleaning force continuation area) that can be cleaned after exposing the pressure-sensitive adhesive sheet becomes too small, it is necessary to increase the outer diameter of the pressure-sensitive adhesive roll as described above to increase the surface area.

Since the adhesive roll comes into direct contact with the surface to be cleaned, the adhesive roll is strongly adhered to the floor such as flooring and carpet and cannot be rolled, and peeling of flocked carpet is avoided. Since it is necessary, the adhesive strength of the adhesive sheet is limited, and the adhesive strength cannot be increased so much. For this reason, if dust adheres to the surface of the adhesive roll, the adhesive force is further weakened, and even if the surface area of the adhesive roll is increased as described above, the cleaning force sustaining area after the new adhesive sheet is exposed is small.

To prevent the pressure-sensitive adhesive roll from sticking strongly to the floor surface and becoming unable to roll, and for the convenience of cleaning gaps, the width of the pressure-sensitive adhesive sheet along the axial direction of the pressure-sensitive adhesive roll is set to 16 mm.
The width is about 0 mm. For this reason, the floor area that can be cleaned by one pass of the adhesive roll is small, and the cleaning efficiency is poor.

[0006]

Another object of the present invention is to increase the cleaning force sustaining area after exposing a new pressure-sensitive adhesive sheet by strengthening the pressure-sensitive adhesive force of the pressure-sensitive adhesive roll without damaging the surface to be cleaned.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 and 2, a cleaning tool 10 has a support arm 13 which is swingably connected in the left-right direction to a tip portion of a handle 11 via a joint portion 12. To both side arm parts 13A of the frame 15 through the support shaft part 14
Is swingably supported in the front-back direction.

A scooping member 16 made of a brush is rotatably supported on the front part of the frame 15 via a rotary shaft 17, and a contact rotary member 18 made of a roll has a rotary shaft 19 on the rear part of the frame 15. The scraping body 16 and the contact rotary body 18 are arranged side by side in parallel with each other. The raking body 16 includes a raking portion 16A (brush portion) and a tire portion 16B, and a raking diameter (brush diameter) of the raking portion 16A is larger than a tire diameter of the tire portion 16B. The contact rotator 18 has a surface formed of an elastic body and is composed of, for example, a silicon roll.
When the adhesive force of the adhesive roll 21 is low, the material of the contact rotary body 18 may not have elasticity. In addition, the contact rotating body 1
8 may be provided with an uneven portion on its surface. The uneven portion means a rib, a convex portion, a concave portion on the roll surface of the contact rotating body 18,
It means that a grain surface is provided.

An adhesive roll 21 straddling the scraping body 16 and the contact rotary body 18 is placed on the scraping body 16 and the contact rotary body 18, and the adhesive roll 21 is rotated along with the rotation of the contact rotary body 18. The upper portion of the frame 15 serves as a loading / unloading port for the adhesive roll 21, and is covered with a transparent cover 22 that can be opened and closed. The pressure-sensitive adhesive roll 21 of the present embodiment is configured by a take-up roll in which the pressure-sensitive adhesive sheet 21A is wound around the core 21B, and the pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet 21A can be unrolled and cut.

The adhesive roll 21 may be movably supported by the frame 15 on its rotating shaft so as not to contact the scraping member 16. That is, the scraping body 16 and the adhesive roll 21 may not be in contact with each other, and the distance between the tip of the brush of the scraping body 16 and the outermost peripheral surface of the adhesive roll 21 is set so that dust is easily adsorbed. It is preferably within about 2-3 mm.

Here, in the adhesive roll 21, the core 21B is composed of, for example, a paper tube having a diameter of 25 mm, and the adhesive sheet 21
The initial outer diameter of A is set to 40 mm or less, more preferably about 35 mm. The adhesive roll 21 is the adhesive roll 2
The width of the adhesive sheet 21A along the axial direction of 1 is 170 to 300 m
It is set within the range of m, more preferably about 195 mm. Further, the adhesive roll 21 is in the range of adhesive coating weight of 25 to 50 g / m ² on the substrate in the pressure-sensitive adhesive sheet 21A, and more preferably is set to about 40 g / m ^2. Kraft paper is preferably used as the base material of the pressure-sensitive adhesive sheet 21A, and a rubber-based pressure-sensitive adhesive can be preferably used as the pressure-sensitive adhesive because it has little odor. In addition, as the base material of the adhesive sheet 21A,
An acrylic adhesive may be used as the glassine paper, pure white paper, or the adhesive. The adhesive sheet 21A of the adhesive roll 21 will be described in detail later.

A dust removing part 23 is supported on the rear part of the scraping body 16 in the frame 15. The dust removing part 23 has a bottom face part 23A in contact with the floor surface, and a rake face part 23B having a curved surface shape (or a flat surface shape) which faces the scraping body 16 without a gap (or via a gap), and has plate shapes on both sides. The support shaft portion 23C is supported on both sides of the frame 15 so as to be vertically movable in oblique rectangular holes 24 that are bent backward with respect to the vertical direction. Dust collector 23
Moves the support shaft portion 23C up and down with respect to the rectangular hole 24 and brings the bottom end portion 23A and the bottom end portion of the rake surface portion 23B into contact with the floor surface without a gap by its own weight, and the scraping portion 16A of the scraping body 16 scrapes up dust. All the dust is removed by the rake face portion 23B without letting it escape backward along the floor surface.
Guide to the side of.

The cleaning operation by the cleaning tool 10 is performed as follows. (1) The cleaning tool 10 is moved forward by an operating force applied in the axial direction of the handle 11, the tire portion 16B of the scraping body 16 and the contact rotary body 18 are rotated, and at the same time, the adhesive roll 21 is rotated together.

(2) When the scraping portion 16A of the scraping body 16 scrapes up dust on the floor surface, this dust is guided by the dust collecting portion 23 and is sent out to the side of the adhesive roll 21, and the adhesive roll 21 Adsorbed and captured on the adhesive surface.

(3) The dust trapped on the adhesive surface of the adhesive roll 21 rotates with the contact roll 18 as the adhesive roll 21 rotates.
To the side of, and is pressed and fixed on the adhesive surface of the adhesive roll 21 by the contact rotator 18. That is, at the time of cleaning, the adhesive roll 21 and the contact rotary body 18 come into contact with each other to capture dust. However, before cleaning or depending on the cleaning situation,
The adhesive roll 21 and the contact rotator 18 are either in contact or non-contact.

(4) When it is visually recognized that a large amount of dust is captured on the entire circumference of the adhesive surface of the adhesive roll 21 from the transparent cover 22, the cover 22 is opened, the adhesive roll 21 is taken out, and one round of the adhesive sheet 21A is taken out. After peeling, cutting and removing the portion to expose the new adhesive surface, the adhesive roll 21 is placed on the scraping body 16 and the contact rotary body 18 again, and the cover 22 is closed.

The cleaning tool 10 can be moved backward as well as forward, and at the time of backward movement, dust on the floor surface adhering to the contact rotor 18 can be adsorbed and captured by the adhesive roll 21. Dust collector 2
3 flips up the tail end portion of the bottom surface portion 23A in a rounded shape, and prevents the tail end portion from being caught on the floor surface during the backward movement.

The pressure sensitive adhesive sheet 21A used in the pressure sensitive adhesive roll 21 of the present invention will be described in detail below.

That is, the adhesive roll 21 is the adhesive sheet 21A.
The tack force of the adhesive surface in 10 is a numerical value based on the inclined ball tack (JIS Z0237-2000), preferably 10 to 30,
12 to 25, and more preferably 14 to 25 are used. If the value based on the inclined ball tack as the tacker is less than 10, the force to attach and hold dirt is weak, and if the surface gets a little dirt such as cotton dust, dirt will not be caught immediately,
The floor area that can be cleaned (cleaning power continuous area) is too small. If the value based on the inclined ball tack as the tack force is larger than 30, the adhesive force is too strong and the operability after mounting the adhesive roll 21 on the cleaning tool 10 is poor, or the adhesive roll 21 is not cleaned. It is difficult to handle because it is sticky to the hands when attaching to.

Examples of the pressure-sensitive adhesive include hot-melt pressure-sensitive adhesives, solvent-based pressure-sensitive adhesives, and water-based pressure-sensitive adhesives. Examples of the hot melt adhesive include styrene-based and olefin-based adhesives. Examples of solvent-based pressure-sensitive adhesives include styrene-based, olefin-based, and acrylic-based pressure-sensitive adhesives. Examples of the water-based pressure-sensitive adhesive include acrylic pressure-sensitive adhesives. As the pressure-sensitive adhesive used in the pressure-sensitive adhesive sheet 21A of the present invention, a styrene-based hot-melt pressure-sensitive adhesive is preferable in view of processability and pressure-sensitive adhesive strength.

Further, the hot melt pressure-sensitive adhesive preferably contains a base polymer, a tackifier component, a softener component and an antioxidant.

As the base polymer, styrene-butadiene rubber (SBR), styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-
Ethylene / butylene / styrene block copolymer (SE
BS), styrene / ethylene / propylene / styrene block copolymer (SEPS) and the like, and when the total amount of the tackifier component and the softening component is 100 parts by weight, 1
It is used in the range of 0 to 100 parts by weight.

Examples of the tackifier component include C5 petroleum resin, C9 petroleum resin, dicyclopetadiene petroleum resin, rosin petroleum resin, polyterpene resin, and terpene phenol resin. It is used in the range of 50 to 90 parts by weight in 100 parts by weight of the total amount of the softening agent components.

The softening agent component preferably includes process oils having a softening point of 10 ° C. or lower and an average molecular weight of 200 to 700, mineral oil, various plasticizers, polybutene, and liquid tackifying resin. Total amount of softener components 10
It is used in the range of 10 to 50 parts by weight in 0 parts by weight.

As the above-mentioned antioxidant, a phenol-based antioxidant, an amine-based antioxidant, a phosphorus-based antioxidant, a benzimidazole-based antioxidant and the like are used, and the total amount of the tackifier component and the softener component is used. When 100 parts by weight is used, it is used in the range of 0.5 to 3 parts by weight.

In addition to these components, components usually used in pressure-sensitive adhesives can be appropriately added within a range that does not impair the desired effects of the present invention.

The amount of the adhesive applied is 25 g /
^{m 2} ~50g / m ^2, preferably ^{25g / m 2 ~40g / m 2} .

When the pressure-sensitive adhesive is applied in an amount of more than 50 g / m ² , when the pressure-sensitive adhesive sheet is wound into a roll, the pressure-sensitive adhesive may stick out from the end of the roll, especially when stored at a high temperature of 30 ° C. or higher for a long time. The protrusion from the roll edge becomes even more remarkable.

As the sheet base material, glassine paper, pure white paper,
Paper such as kraft paper can be used. In particular, when a stretched paper having high tear strength is used, even when fibrous dust such as hair is wrapped around the adhesive roll, the soiled adhesive sheet can be easily peeled off without tearing. Also,
As the sheet base material other than paper, films such as polyester and polypropylene may be used. However,
When using a hot melt adhesive as an adhesive, it is necessary to use a heat resistant film.

A silicone-based release agent is applied to the back of the adhesive surface of the adhesive sheet. At this time, a release agent is applied after laminating with low-density polyethylene as a stopper according to the sheet base material. The types of release agent and sealing resin used at this time are not limited to these.

Further, a commercially available adhesive roll cleaner is constructed by winding an adhesive sheet around a core such as a paper tube with the adhesive surface facing outward. By providing perforations along the entire length in the perpendicular direction and slits at the width end of the roll in the perpendicular direction, the unwound adhesive sheet can be cut with both hands. However, it is difficult to cleanly separate the pressure-sensitive adhesive sheet in the width direction, and the separating operation itself is complicated. In particular, when the adhesive roll is mounted in the cleaning tool of this embodiment, this separating operation becomes more complicated. Therefore, the pressure-sensitive adhesive sheet of the pressure-sensitive adhesive roll is preferably a pressure-sensitive adhesive roll of a type that is preliminarily cut for each roll. Furthermore, by using an adhesive roll of a type in which an independent adhesive sheet is spirally wound around a winding core, a dirty sheet can be easily spiraled by simply picking up and pulling up the sharp tip of the narrow adhesive sheet. It is desirable because it can be peeled off.

Further, it is clear from the following experimental results that the lower limit of the numerical value based on the inclined ball tack of the adhesive surface of the adhesive sheet 21A of the adhesive roll 21 in the present invention should be set to 10. If the value based on the tilting ball tack is larger than 30, the adhesive force is too strong and the operability after mounting on the cleaning tool is poor, or the adhesive roll 21 is used as the cleaning tool 1.
When attached to 0, it is difficult to handle because it is sticky to the hands. Therefore, the upper limit of the numerical value based on the inclined ball tack is set to 30.

(1) As the tacking force of the adhesive roll, those having numerical values based on the inclined ball tack as in the following Examples 1 to 3 and Comparative Examples 1 and 2 were prepared.

Incidentally, the numerical test device and test method based on the tilt type ball tack is Z023 of Japanese Industrial Standard (JIS).

The test piece 33 is attached with the adhesive surface facing upward at a predetermined position on the inclined plate 34 using an adhesive tape for stopping the upper end and the lower end of the test piece 33.

Next, a polyethylene terephthalate (PET) film for the runway 35 (length 100 mm or more, thickness 25 μm: J
A transparent film specified in IS C2318) is attached to a predetermined position of the test piece 33.

The PET film should be attached so that it does not contain air bubbles or wrinkles, and it should not be strongly pressure-bonded.

When mounting the test piece 33 on the inclined plate 34, take care so that the test piece 33 does not float, wrinkle or bend, and if the edge curls and floats, touch that part. Fix it on the board with another adhesive tape.

(2-1) Hair collection rate test method A (initial state:
(There is no stain on the surface of the adhesive sheet due to model adhesion)

To initialize the carpet, a cleaning machine with a rotating brush is used, and the cleaning area is 50 cm in the carpet mode.
× 50cm carpet (commercially available cut pile carpet [Sangetsu Sun Harmony (trade name), fiber: 85% acrylic, 15% nylon, pile length: 8mm, density: gauge 1
/ 10, Stitch 14.5]) Clean the top.

As a method of spraying hair, 10 hairs having a length of 10 cm are evenly sprayed on the carpet.

As a method for cleaning the carpet, an adhesive roll uses an indirect collecting type cleaning tool that does not directly contact the cleaning surface, and the cloth is reciprocated 5 times on the carpet to collect the number of hairs adhered to the adhesive sheet by the following formula. Calculate the rate (%). Collection rate (%) = (number of adhered hair) / (number of scattered hair) x 100

The above steps (1) to (3) are repeated three times, and the average value is used as the hair collection rate.

100

(3) Test result The test results are summarized in Table 1 below.

[0073]

[Table 1]

As is clear from Table 1, by setting the lower limit of the numerical value based on the inclined ball tack of the adhesive surface of the adhesive sheet 21A of the adhesive roll 21 in the present invention to 10, the hair collection rate and the bread crumbs collection are achieved. It is recognized that both the rates are significantly improved as compared with the comparative example. Further, as described above, by setting the upper limit of the numerical value based on the tilt type ball tack to 30, the adhesive force is too strong and the operability after mounting the adhesive roll 21 on the cleaning tool 10 is poor, or the adhesive roll 2
When the cleaning tool 10 is attached to the cleaning tool 10, it does not become sticky to the hands or the like and becomes difficult to handle.

According to this embodiment, there are the following effects. (1) The pressure-sensitive adhesive roll 21 is configured by winding the pressure-sensitive adhesive sheet 21A around the core 21B and has an initial outer diameter of 40 mm or less, which makes the cleaning tool 10 compact. Adhesive roll 2
Since 1 does not come into direct contact with the surface to be cleaned, it does not adhere to the surface of the adhesive roll 21 by scraping off the flock of carpet or the like other than dust, so that the adhesive force is immediately applied even if the surface area of the adhesive roll 21 is small. It never weakens.
Therefore, even if the outer diameter of the pressure-sensitive adhesive roll 21 is reduced to a small surface area as described above, the amount of dust captured by the pressure-sensitive adhesive roll is increased to increase the cleaning force sustaining area after the new pressure-sensitive adhesive sheet 21A is exposed. You can

(2) Since the adhesive roll 21 does not come into direct contact with the surface to be cleaned, the adhesive roll 21 strongly adheres to the flooring or the like and may not roll, and the flock of carpet or the like is peeled off to damage the surface to be cleaned. Without fear, adhesive sheet 2
The coating amount of the adhesive on the base material 21B of 1A is 25 to 50 g / m
^It can be increased to ² to increase the adhesive strength. Therefore, the amount of dust captured by the adhesive roll is increased and the new adhesive sheet 21A
It is possible to increase the cleaning power sustaining area after the exposure.

(3) By setting the numerical value based on the inclined ball tack of the adhesive surface of the adhesive sheet 21A of the adhesive roll 21 in the present invention within the range of 10 to 30, the adhesive roll 2
The adhesive force of the first adhesive sheet 21A is not too strong, and the force for adhering and holding dirt such as hair is maintained, and the cleanable area can be increased.

(4) Since the width of the pressure-sensitive adhesive sheet 21A along the axial direction of the pressure-sensitive adhesive roll 21 is widened to 170 to 300 mm, the floor area that can be cleaned by one forward movement of the pressure-sensitive adhesive roll 21 is widened to improve the cleaning efficiency. Can be improved.

(5) The scraping body 16 immediately removes the scraped dust by adsorbing it to the adhesive roll 21 side, and does not leave the hair or the like entangled and remains clean by contact with the adhesive roll 21. The cleaning performance can be stably maintained.

(6) The contact rotator 18 mounts the adhesive roll 21 and rotates the adhesive roll 21 with it. Therefore, the adhesive surface of the adhesive roll 21 in contact with the scraping body 16 is constantly made new by rotation, and the dust sucked up by the scraping body 16 can be surely sucked and captured by the new suction surface of the adhesive roll 21. At this time, since the adhesive roll 21 is laid over the scraping body 16 and the contact rotating body 18, the adhesive roll 21 of any size, large or small, having any outer diameter can be cleaned.
Can be loaded at 0. Therefore, the outer diameter of the pressure-sensitive adhesive roll 21 has a degree of freedom in manufacturing, and the pressure-sensitive adhesive roll 21 having an appropriate outer diameter can be selected according to the floor condition.

(7) The contact rotating body 18 presses the dust adsorbed and captured by the adhesive roll 21 against the adhesive surface of the adhesive roll 21 and contributes to fixing the captured state of the dust. The dust caught by the contact rotor 18 coming into contact with the floor surface is also adsorbed and captured by the adhesive roll 21, and the adhesive roll 21 keeps the contact rotor 18 clean.

(8) The dust scraped up by the scraping body 16 from the deep portion of the fiber of the carpet and the dust scraped backward from the hard flat surface of the flooring are scooped up by the dust collecting part 23 at the rear part of the scraping body 21. And surely adhesive roll 2
Guided in the direction of 1, the dust collection performance can be improved.

(9) Since the scraping body 16 is provided with the tire portion 16B, the tire portion 16B is pressed against the floor surface by the weight of the cleaning tool 10 and rotates, thereby reliably rotating the scraping body 16. Since the scraping diameter is made larger than the tire diameter, the scraping portion 16A strongly scrapes dust by the scraping force based on the restoration of the elastic deflection to improve the scraping performance and also the dust in the deep part of the fiber of the carpet. You can scrape it well.

(10) Since the contact rotating body 18 is provided with the elastic body surface, dust adhered and captured by the adhesive roll 21 can be well pressed and fixed on the adhesive surface of the adhesive roll 21.

(11) When the adhesive force of the adhesive roll 21 is strong,
Since the adhesive roll 21 and the contact rotator 18 rotate together, the rotation is difficult and the operation becomes heavy. Therefore, by providing at least two uneven portions on the surface of the contact rotator 18, the rotation can be lightened. That is, the provision of the concavo-convex portion on the contact rotary body means that the adhesive roll 21 and the contact rotary body
A gap is formed between the two and the contact area between the two and the operability can be improved. Since the dust adhered to the contact rotator 18 is transferred to the adhesive roll 21 without the adhesive roll 21 and the contact rotator 18 being in close contact with each other, the preferable height of the uneven portion is when the material of the contact rotator 18 is polypropylene. 0.1-0.5 mm, more preferably 0.
It is 2 to 0.4 mm, and may be lower than these values in the case of silicone rubber. Here, the concavo-convex portion means the contact rotating body 18
It means that ribs, convex portions, concave portions, grain surfaces, etc. are provided on the surface of the.

As the pressure-sensitive adhesive roll used in the present invention, a core roll which is detachably covered with a cylindrical sheet may be used. At this time, the original shape of the tubular sheet is a sheet-type envelope sheet, and a large number of envelope sheets can be stacked and stored.

Further, in the present invention, the scraping body is not limited to the brush, but may be a sponge, a rubber blade, an elastomer, an elastic protrusion, or the like.

Further, in the present invention, the contact rotary body is not limited to the roll body, but may be a tire or the like.

As described above, according to the present invention, it is possible to increase the cleaning force continuation area after exposing the novel adhesive sheet of the adhesive roll, while making the cleaning tool compact. Further, according to the present invention, it is possible to increase the adhesive force of the adhesive roll and increase the cleaning force sustaining area after the new adhesive sheet is exposed, without damaging the surface to be cleaned. Further, according to the present invention, it is possible to widen the floor area that can be cleaned by one pass of the adhesive roll and improve the cleaning efficiency.
