Description

  The present invention relates to a type of technology that uses adhesiveness as a means for removing dirt caused by adhesion of foreign matters. More specifically, one is a high-performance rotary adhesive cleaner that can be used easily at home, workplace, factory, school, hospital, and other places, and the other is reasonable. The present invention relates to an improved adhesive roller for a cleaner.

  Regarding adhesion and adhesion, when adhesion is considered as a superordinate concept and adhesion is considered as a subordinate concept, the adhesion is considered to be a kind of adhesion. However, practical pressure-sensitive adhesive materials (pressure-sensitive adhesives) exhibit a sticky state such as highly viscous liquids and gel-like solids, and are therefore distinguished from adhesive materials (adhesives) that solidify and exhibit peeling resistance. .

  The above adhesive material is used in an adhesive cleaner as an example. In the case of this adhesive cleaner, an adhesive material is applied to a predetermined surface of the cleaner, the adhesive material application surface is pressed against the surface of the object to be cleaned, and then peeled off. In this way, foreign matters (dust etc.) are adhered and transferred from the object to be cleaned to the surface of the cleaner to which the adhesive material is applied, whereby the foreign matters are removed from the object to be cleaned. That is, the cleaning object is cleaned.

  Many sticky cleaners are already available. Typical examples are disclosed in Patent Documents 1 to 3 below. These literature techniques are described below.

  The adhesive cleaner disclosed in Patent Document 1 is mainly composed of a rotatable adhesive roller, and an adhesive layer is formed on the surface of the adhesive roller. The adhesive cleaner disclosed in Patent Document 1 removes dust or the like on the surface of the cleaning object by adhering with the adhesive layer on the surface of the adhesive roller by rolling the adhesive roller against the surface of the object to be cleaned. The core of the adhesive roller in this case is cylindrical, and it is described that a plastic molded body is particularly desirable. An adhesive layer is formed on this cylindrical core by winding an adhesive tape.

  The adhesive cleaner disclosed in Patent Document 2 is a combination of a transfer roller, an adhesive roller, and a transport roller. Regarding the layout of each roller, the transfer roller is arranged at the center, the adhesive roller is arranged on the left side (or right side) of the transfer roller, and the conveyance roller is arranged on the right side (or left side) of the transfer roller. It is in line contact. In the case of such an adhesive cleaner, when the long flexible sheet (object to be cleaned) passes between the transport roller and the transfer roller, dust adhered to the surface of the long flexible sheet. Is captured by the peripheral surface of the transfer roller, and dust adhering to the peripheral surface of the transfer roller is captured by the peripheral surface of the adhesive roller. This is because the dust on the surface of the long flexible sheet is removed by the dust displacement of the surface of the long flexible sheet → the peripheral surface of the transfer roller → the peripheral surface of the adhesive roller. In the case of Patent Document 2, the material of each roller is not particularly limited. However, for adhesive rollers that need to be replaced periodically, an adhesive roll (adhesive roller) composed of multiple layers of adhesive tape is used to reduce the decrease in dust removal effect due to a decrease in adhesive strength. There is a description that the lowered adhesive tape layer may be peeled off.

  The adhesive cleaner disclosed in Patent Document 3 is a cylindrical tubular adhesive cleaning roller in which a thick soft elastic layer (inner layer) and a thin adhesive layer (outer layer) are integrally formed. It is. In this case, both the soft elastic layer and the adhesive layer are made of a soft thermoplastic elastomer. The adhesive cleaner (adhesive cleaning roller) disclosed in Patent Document 3 rolls an adhesive cleaning roller while applying it to a semiconductor substrate with components during cleaning. At that time, the rolling surface (outer peripheral surface) of the adhesive cleaning roller is deformed so as to conform to the unevenness of the semiconductor substrate, and adhesion and peeling are continuously repeated. The dust on the semiconductor substrate side adheres to the outer peripheral surface of the adhesive cleaning roller by this cleaning operation. Therefore, the semiconductor substrate is dedusted.

Japanese Patent Laid-Open No. 08-024206 JP 2000-288483 A JP 2007-175473 A

In the case of each of the adhesive cleaners disclosed in Patent Documents 1 to 3 described above, appropriate results have been achieved with respect to adhesive dust removal, but these techniques are improved as pointed out in the following <01> to <05>. There is room for.
<01> The adhesive cleaner of Patent Document 1 has an adhesive layer formed on the outer peripheral surface of a solid roller core. Such solid-type adhesive cleaners are generally hard and heavy, and costly, although there is no shortage of strength. In addition, since the roller has poor deformability and is not suitable for a cleaning object having irregularities, the applicable cleaning object is limited to a flat cleaning surface.
<02> The adhesive cleaner of Patent Document 1 that has an adhesive tape rolled around the outer peripheral surface of the roller core has an initial adhesive dust removal capability by cutting off the used adhesive tape portion to which dust has adhered. An adhesive tape part can newly appear. This is because the adhesive dust removal force of the adhesive cleaner is in the initial state (unused state), but on the other hand, since expensive adhesive tape is disposable, it is undesirable in terms of resource saving and cost control. become.
<03> The adhesive cleaner of Patent Document 2 also has the same problem as the above <01> because the adhesive roller is a solid type similar to that of Patent Document 1. Furthermore, since the roll-wrapped adhesive tape method described above is used in measures to reduce the dust removal capability of the adhesive roller, the same problem as the above <02> is observed.
<04> The cleaning roller in the adhesive cleaner described in Patent Document 3 is easily deformed because its inner layer is made of a soft elastic layer. Since the surface of this soft type cleaning roller is well adapted to the cleaning surface of the object to be cleaned, the adhesive dust removing effect during the cleaning process is enhanced accordingly. However, this cleaning roller is considerably less easily deformable than, for example, a soft foam (soft sponge). Therefore, the cleaning roller of Patent Document 3 still has room for improvement in that it can be sufficiently deformed even with a small force to cope with various large and small uneven surfaces.
<05> In the adhesive cleaner described in Patent Document 3, the cleaning roller is a solid type, and therefore improvement in weight reduction is desired. In addition, since the soft elastic layer (inner layer) and the adhesive layer (outer layer) are two-stage extruded simultaneously, the cleaning roller is more difficult to manufacture than simple one-stage extrusion.

  In view of such technical problems, the present invention is intended to satisfy the demands for resource saving, cost reduction, production difficulty reduction, etc. while measuring the high level, stability, recovery and weight reduction of the adhesive dust removal function. It is an object of the present invention to provide an adhesive cleaner roller and a rotary adhesive cleaner.

The roller for adhesive cleaner according to the present invention and the rotary adhesive cleaner according to the present invention are characterized by means for solving the following problems <11> to <16> in order to achieve the intended purpose.
<11> a roller main material having a soft porous outer layer on the outer peripheral portion and an adhesive material for forming an adhesive film layer; and
The outer peripheral surface of the soft porous outer layer in the roller main material has an uneven rough surface, and
The pressure-sensitive adhesive material is coated on the outer peripheral surface of the soft porous outer layer of the roller main material to form an adhesive film layer, and a part of the lower layer of the pressure-sensitive adhesive film layer is the outer periphery of the soft porous outer layer. An adhesive cleaner roller that is fitted in a recess in the surface.
<12> The above roller main material is formed of an extruded cylindrical soft foam, and the outer surface of the soft porous outer layer of the roller main material is processed to have an uneven rough surface. <11> An adhesive cleaner roller according to <11>.
<13> The adhesive cleaner roller according to any one of <11> to <12>, wherein the soft porous outer layer of the roller main material is made of closed cells.
<14> The adhesive cleaner roller according to any one of <11> to <13>, wherein the roller main material has a dense coating layer on an inner peripheral surface thereof.
<15> An adhesive cleaner roller according to any one of the above <11> to <14>,
A rotary adhesive cleaner comprising a rotating support shaft provided at a shaft center portion of the adhesive cleaner roller.
<16> An adhesive cleaner roller according to any one of the above <11> to <14>,
A support shaft for rotation provided at the shaft center of the adhesive cleaner roller;
A rotary adhesive cleaner comprising a handle for a handle provided on the support shaft.

The adhesive cleaner roller and the rotary adhesive cleaner according to the present invention have effects as described in the following <21> to <25>.
<21> With regard to the adhesive cleaner roller, the roller main material has a soft porous outer layer and an adhesive film layer. Among these, one of the soft porous outer layers is easily deformed because it is soft and porous. As is obvious, the other adhesive film layer coating the outer peripheral surface of the soft porous outer layer is also easily deformed because it is film-like. Of course, in the case of the adhesive film layer, the deformability of the soft porous outer layer is not hindered. That is, the adhesive cleaner roller has a configuration for sufficiently exhibiting easy deformability. When such an adhesive cleaner roller is pressed against the cleaning surface of the object to be cleaned, the adhesive film layer is in pressure contact with the cleaning surface of the object to be cleaned, and dust (stain-causing particles or contamination-causing particles) on the cleaning surface The adhesive is captured so as to envelop. When the trapped adhesive film layer is separated from the cleaning surface of the object to be cleaned, dust on the cleaning surface side of the cleaning object is peeled and moved to the adhesive film layer side and removed from the cleaning surface. Therefore, when this adhesive cleaner roller is used, a high degree of adhesive dust removal function is demonstrated by the cooperation of the soft porous outer layer of the roller main material and the adhesive film layer, thereby cleaning the cleaning surface of the object to be cleaned at a high dust removal level. It is made.
<22> The easy-deformable adhesive cleaner roller adheres sufficiently to the cleaning surface of the object to be cleaned even with a small pressing force, and this is done gently, damaging the cleaning surface of the object to be cleaned. There is no fear. On the other hand, as for the soft porous outer layer and the adhesive film layer of the roller main material, a part of the lower layer portion of the adhesive film layer is fitted in the recess on the outer peripheral surface of the soft porous outer layer. In this case, the adhesive film layer not only exhibits an adhesive effect on the soft porous outer layer, but also exerts an anchoring effect (anchor effect, wedge effect, fastener effect) by biting into the recess of the soft porous outer layer. It is. In addition, since the outer peripheral surface of the soft porous outer layer has a large surface area such as an uneven rough surface, the effective adhesive surface area of the adhesive film layer with respect to the soft porous outer layer is also large. That is, the adhesive film layer is strongly and firmly integrated with the soft porous outer layer by a synergistic effect of the adhesive effect, the anchoring effect and the large adhesive surface area. Therefore, in the case of an adhesive cleaner roller that is handled by rolling while pressing against the cleaning surface of the object to be cleaned, there is a problem that a part of the adhesive film layer peels off from the soft porous outer layer and sticks to the cleaning surface side. The above-mentioned advanced adhesive dust removal function is stably demonstrated over a long period of time.
<23> As described above, the main component of the adhesive cleaner roller is that the adhesive film layer is strongly and firmly bonded (adhered) to the soft porous outer layer. Is stable. Therefore, the adhesive cleaner roller exhibits an adhesive dust removing function while sufficiently withstanding high-frequency use (repeated use). Nonetheless, in the case of an adhesive cleaner roller that is used repeatedly, the removed dust adheres to and accumulates on the adhesive film layer as it is used. Ability or cleaning ability) is reduced. In this regard, the accumulated dust can be easily washed away from the adhesive film layer by washing the adhesive film layer with water or the like in a timely manner. Of course, this restores the adhesive strength of the adhesive film layer to almost the initial state. Therefore, it can be said that the adhesive cleaner roller is desirable for the recovery of the adhesive dust removing function.
<24> One of such existing technologies is a roller in which an adhesive sheet is wound into a roll. In such an existing technology, the removed dust adheres to and accumulates on the adhesive sheet with use. Therefore, the used adhesive sheet is cut off when a certain amount of removed dust adheres to and accumulates on the adhesive sheet. The part (new adhesive sheet part) is exposed. In this type, the roll-wrapped pressure-sensitive adhesive sheet must be compensated every time it is used up, so that the maintenance cost increases, and cumbersome roll replacement is also required. On the other hand, in the case of the above-mentioned adhesive cleaner roller that can restore the adhesive dust removal function only by a simple cleaning process, not only the maintenance work is required, but also the maintenance cost for that is greatly reduced. be able to.
<25> In the case of the above-mentioned adhesive cleaner roller that continues to be used without exhausting its constituent materials, this also satisfies the resource saving requirements.
<26> In the case of the above-mentioned adhesive cleaner roller, the roller main material, etc., is composed of an inexpensive two-layer structure mainly composed of a soft porous outer layer and an adhesive film layer, so that the cost is low. This is because the maintenance cost can be significantly reduced in addition to the low cost of the product, so that the total cost for the adhesive cleaner roller is significantly reduced.
<27> The roller main material of the above-mentioned adhesive cleaner roller is a lightweight material having a soft porous outer layer having a porous structure and an adhesive film layer having a light structure having a film structure. The adhesive cleaner roller, which is generally lightweight, has a light load even if it is rotated by mechanical means or manually. In particular, a manual cleaner roller having a handle attached to an adhesive roller for a liner has good operability during use because the substrate is lightweight.
<28> In the case of the above-mentioned adhesive cleaner roller, for example, it is only necessary to produce a roller main material having two required layers such as a soft porous outer layer and an adhesive film layer, and this can be obtained with simple and few steps. . Therefore, the manufacturing difficulty of the adhesive cleaner roller is greatly reduced, and the manufacture thereof can be performed rationally.
<29> The above adhesive cleaner roller is composed of a cylindrical soft foam formed by extruding the roller main material, and the outer surface of the soft porous outer layer of the roller main material is roughened by roughening the outer surface. For those having a shape, the adhesive cleaner roller can be obtained more easily and accurately through the extrusion molding means and the surface processing means.
<30> For the above-mentioned adhesive cleaner roller, when the soft porous outer layer of the roller main material is made of closed cells, it is easy to form an adhesive film layer accurately by confining to the surface area of the soft porous outer layer. It is also possible to avoid an unsanitary state in which dust or the like adhering to the adhesive film layer enters and stays in the soft porous outer layer. When the soft porous outer layer is made of closed cells, moisture does not enter the soft porous outer layer, so that the draining effect when the adhesive film layer is washed with water is high.
<31> For the above adhesive cleaner roller, when the cylindrical roller main material has a dense coating layer on the inner peripheral surface of the soft porous outer layer, the inner surface of the soft porous outer layer depends on the coating layer. The strength of the peripheral surface can be ensured. This is desirable because the inner peripheral surface of the soft porous outer layer is less likely to be damaged in handling when a rotation support shaft is provided at the shaft center of the adhesive cleaner roller.
<32> One of the rotary adhesive cleaners according to the present invention includes the above-described adhesive cleaner roller and a rotation support shaft provided at the shaft center of the adhesive cleaner roller. is there. This rotary adhesive cleaner has the above-mentioned effects because it includes an adhesive cleaner roller as a main component. In particular, this rotary adhesive cleaner is suitable for being rotated by mechanical means.
<33> Another one of the rotary adhesive cleaners according to the present invention includes the above-described adhesive cleaner roller, a rotary support shaft provided at the shaft center of the adhesive cleaner roller, and the support shaft. Is provided with a handle for a handle provided on the head. This rotary adhesive cleaner also has the above-mentioned effects because it includes an adhesive cleaner roller as a main component. In particular, this rotary adhesive cleaner has good operability when used as a manual type.

It is the perspective view which showed one Embodiment of the roller for adhesive cleaners which concerns on this invention. It is the perspective view which showed the raw material of the roller for adhesive cleaners shown in FIG. It is a partially expanded sectional view of the roller for adhesive cleaners shown in FIG. 1 is a longitudinal sectional view schematically showing a first embodiment of a rotary adhesive cleaner according to the present invention. It is the longitudinal cross-sectional view which showed the 2nd embodiment about the rotary adhesive cleaner which concerns on this invention. FIG. 6 is a partially cutaway perspective view schematically showing a third embodiment of the rotary adhesive cleaner according to the present invention. It is principal part sectional drawing of the rotary adhesive cleaner of FIG.

  What is illustrated in the embodiment of FIGS. 1 to 3 as the adhesive cleaner roller 11 according to the present invention has a roller main material 21 and an adhesive film layer 31 as main components.

  Of these, the roller main member 21 is made of an elastomer. More specifically, the roller main material 21 is made of a soft synthetic resin or synthetic rubber, and most of the portion has a porous or porous structure (sponge structure). The porous structure in this case may be a closed cell body or an open cell body. The preferred porous structure is due to closed cells. The roller main material 21 may be any of a cylinder, a circular tube, a round bar, and the like, but among these, a cylindrical tube or a cylindrical tube is preferable.

  The roller main material 21 illustrated in FIGS. 1 and 3 is made of a “tubular soft synthetic resin foam” or “tubular soft synthetic rubber foam” as is apparent from FIG. "Body". A typical material 25 is made by a well-known extrusion means, and has a porous structure of closed cells. As shown in FIG. 2, the roller main material 25 has two dense coating layers 22 and 26 called cure layers on the inner and outer peripheral surfaces thereof. However, one coating layer 26 of both coating layers 22 and 26 is deleted from the outer peripheral surface of the raw material 25 by surface processing for scraping the surface layer portion. Therefore, the coating layer 22 is left on the inner peripheral surface of the roller main material 21, and the soft porous outer layer 23 having a thickness larger than the coating layer 22 exists on the coating layer 22. Furthermore, the outer peripheral surface 24 of the soft porous outer layer 23 has a rough surface as a result of the removal of the one coating layer 26. Furthermore, the rough outer circumferential surface 24 of the soft porous outer layer 23 is formed by a mixture of air bubbles that are not crushed by closed cells and air bubbles that are crushed by closed cells.

The soft roller main material 21 is made of an elastomer having rubber-like elasticity. In this case, the elastomer may be a synthetic resin or a synthetic rubber as described above. Polyurethane resin, polystyrene resin, polyolefin resin (polyethylene resin and polypropylene resin), etc. are raised as the elastomer to be foamed. In addition, phenol resin, polyvinyl chloride resin, urea resin, silicone resin, polyimide resin, melamine resin, etc. Is raised. As the elastomer for the roller main material 21, one that is usually foamed independently with a thermoplastic synthetic resin is often selected. As a specific example of the elastomer for the roller main material 21, EPDM (Ethylene-Propylene-Diene Methylene linkage), that is, ethylene propylene diene terpolymer is selected as the material of the roller main material 21, and it is foamed. Extruded as a cylindrical tubular soft resin foam containing agent and others. In this case, the hardness of the soft resin foam is JIS-C and has a hardness of about 15 to 25, and the bubbles of the soft resin foam have a diameter of about 0.5 to 1 mm. The expansion ratio of the soft resin foam (value obtained by dividing the volume of the foam by the volume of the solid) is 2 to 5 times. Furthermore, the specific gravity of the soft resin foam is 0.35 to 0.5 g / mm ³ . The dimensions of the roller main member 21 that are only examples are length (dimension in the axial direction) = 160 mm and outer diameter (diameter) = 56 mm.

  With respect to the soft and cylindrical roller main material 21, an adhesive material (adhesive) for forming an adhesive film layer is coated on the outer peripheral surface 24 of the soft porous outer layer 23, which forms an uneven rough surface, thereby forming an adhesive film layer 31. Is formed on the outer peripheral surface 24 of the soft porous outer layer 23. As the adhesive material for forming the adhesive film layer, an arbitrary material selected from urethane adhesive materials, silicone adhesive materials, acrylic adhesive materials, rubber adhesive materials, and the like is employed. These adhesives are also available in various types such as solvent-based (acrylic, rubber-based, silicone-based, etc.), emulsion-based (acrylic-based, etc.), UV-curing (acrylic-based, etc.), hot-melt (rubber-based), etc. Since there is a type, the coating means for the roller main material 21 is selected accordingly. By the way, as an example of some of the coating means, one is a method of immersing the roller main material 21 in the adhesive material, and the other is the method of immersing the adhesive material on the outer peripheral surface 24 of the soft porous outer layer 23 in the roller main material 21. Another application method is a method of transferring the adhesive material to the outer peripheral surface 24 of the soft porous outer layer 23 in the roller main material 21. These methods are all known or well known. In addition, the adhesive strength of the adhesive material can be freely set according to the application.

  As a more specific example, the outer peripheral surface 24 of the soft porous outer layer 23 in the roller main material 21 is coated with a urethane-based adhesive material through the above-described dipping method, whereby the adhesive film layer 31 becomes the soft porous outer layer. 23 is formed on the outer peripheral surface 24. The adhesive film layer 31 in this case is set to an appropriate thickness based on the type of adhesive material and the required adhesive force, but the thickness is generally within the range of 0.001 to 1.5 mm. Desirably, it is set within a range of 0.01 to 0.5 mm. About the adhesive film layer 31 formed with the above-mentioned adhesive material, the adhesive force is suitably set like strong / medium / weak. By the way, the adhesive strength of the adhesive film layer 31 in the case of strong adhesive is about 450 tack, the adhesive strength of the adhesive film layer 31 in the case of medium adhesive is about 110 tack, and the adhesive strength of the adhesive film layer 31 in the case of weak adhesive. The force is about 30 tack. The adhesive film layer 31 may further include any one or more or all of antibacterial agents, sterilizing agents, bactericides, deodorants, fragrances, color formers, fluorescent agents, and the like. These agents are known or well known in the form of natural products and synthetic materials including organic, inorganic and mixed systems. Among them, the following are known antibacterial agents. For example, in the case of natural products, there are Chinese herbal ingredients such as Soso bamboo extract, hinokitiol, garlic extract, and licorice. In addition, examples include inorganic antibacterial agents such as silver, copper, zinc, tin, lead, and gold. If necessary, zeolite, hydroxyapatite, calcium carbonate, silica gel, aluminum calcium silicate, polysiloxane compound, zirconium phosphate, zirconium sulfate, ion exchanger, zinc oxide, etc. can be used as a carrier for these inorganic antibacterial agents. it can. On the other hand, for the synthetic system, 2-pyridinethiol-1-oxide / p-chloro-m-cresol / polyhexamethylene hyguanide / hydrochloride / benzethonium chloride / alkylpolyaminoethylglycine / benzisothiazoline / 5-chloro- Examples include 2-methyl-4-isothiazolin-3-one / 1,2-benzisothiazolin-3-one / 2,2′-dithio-bis- (pyridine-1-oxide). Among these, 2-pyridinethiol-1-oxide and benzisothiazoline are preferable in terms of antibacterial activity and solubility. Of course, these may be used in combination of two or more. This type of antibacterial agent is dissolved or uniformly dispersed and contained in the pressure-sensitive adhesive layer.

  About the roller 11 for adhesion | attachment cleaners, another roller main material may be loaded in the roller main material 21, and the laminated structure of two or more layers may be sufficient as it. In this case, it is desirable that another roller main material loaded in the roller main material 21 is also soft rubber or synthetic resin. In the relative relationship between the two roller members, there are a case where the roller main material 21 is softer than another roller main material and a case where another roller main material is softer than the roller main material 21.

  The rotary adhesive cleaner 41 according to the present invention illustrated in FIG. 4 corresponds to the first embodiment. Further, the rotary adhesive cleaner 41 illustrated in FIG. 4 includes the above-described adhesive cleaner roller 11 as a main component, and is combined with a rotating support shaft 51.

  The support shaft 51 of the rotary adhesive cleaner 41 illustrated in FIG. 4 may be made of a soft material as long as the hardness exceeds that of the roller main material 21. However, the material of the support shaft 51 is more preferably a hard material, and this hard material is often adopted as the material of the support shaft 51. Specifically, the support shaft 51 is made of synthetic resin, metal, wood, bamboo, or cardboard (eg, paperboard made of four to five layers), or two of these materials. Although it is made of a composite material by the above combination, representative ones are those made of synthetic resin or metal. Whether the support shaft 51 is a hollow shaft or a non-hollow shaft (non-hollow rod-shaped shaft) is an optional item to be determined in consideration of strength, weight, cost, and the like. From the viewpoint of giving priority to weight reduction and low cost, a hollow support shaft 51 as shown is employed.

  4, when the inner diameter (diameter) of the roller main material 21 is D1 and the outer diameter (diameter) of the support shaft 51 is D2, these are [D1> D2] and [D1 = D2]. ] Or [D1 <D2]. Among these, in the case of [D1> D2] and [D1 <D2], the inner / outer diameter difference between D1 and D2 is usually a small difference of less than 1 mm such as 0.1 mm to 0.8 mm. Further, in the case of [D1 = D2] or [D1 <D2], the inner peripheral surface of the roller main member 21 and the outer peripheral surface of the support shaft 51 are brought into close or close contact with each other, so that frictional resistance is generated. 51 is not easily detached from the roller main material 21. On the other hand, in the case of [D1> D2], an adhesive (adhesive) is applied to the inner peripheral surface of the roller main member 21 or the outer peripheral surface of the support shaft 51 or the inner and outer peripheral surfaces thereof partially or entirely. The above-mentioned detachment can be prevented by relatively bonding the main material 21 and the support shaft 51.

  Further, with respect to the rotary adhesive cleaner 41 of FIG. 4, when the axial length (dimension) of the roller main material 21 is L1, and the axial length (dimension) of the support shaft 51 is L2, [L1 > L2], [L1 = L2], or [L1 <L2]. This dimension in a representative embodiment of the rotary adhesive cleaner 41 is [L1 = L2] or [L1 <l2]. The rotary adhesive cleaner 41 of FIG. 4 is also [L1 = L2]. When the roller main material 21 and the support shaft 51 are [L1 <L2], one end portion or both end portions of the support shaft 51 protrude from one end portion or both end portions of the roller main material 21.

  The main function of the support shaft 51 in the rotary adhesive cleaner 41 is support when the rotary adhesive cleaner 41 rotates. Besides, the support shaft 51 prevents the soft and tubular roller main material 21 from being bent or flattened. That is, the support shaft 51 has a shape maintaining function of preventing the roller main material 21 or the adhesive cleaner roller 11 from being deformed to an undesired state (the above-described bending deformation or crushing deformation).

  The rotary adhesive cleaner according to the present invention illustrated in FIG. 5 corresponds to the second embodiment. Further, the rotary adhesive cleaner 41 illustrated in FIG. 5 is a combination of the first support shaft 51 and the second support shaft 52 in the first embodiment (FIG. 4). is there.

  In the rotary adhesive cleaner 41 of FIG. 5, the material or material of the second support shaft 52 may be the same as or different from that of the first support shaft 51. As the material of the second support shaft 52, an appropriate material is selected from the various materials described in paragraph 0019. In that case, the desired material is hard.

  In the rotary adhesive cleaner 41 of FIG. 5, the second support shaft 52 illustrated here is a hollow tubular tube. In terms of the relationship between the first support shaft 51 and the second support shaft 52, the second support shaft 52 penetrates through the inside of the first support shaft 51 and both ends thereof are the first support shaft 51. It protrudes out of the both ends. As an example in this case, both the support shafts 51 and 52 are fitted so as to be relatively rotatable, and as another example, the both support shafts 51 and 52 are relatively fixed so that they do not move in the axial direction or the circumferential direction. Is done. The both spindles 51 and 52 are fixed by well-known means such as interference fitting, adhesion (adhesion), and fixing of fasteners.

  In the rotary adhesive cleaner 41 of FIG. 5, other matters are substantially the same as or similar to the contents described with reference to FIGS. 1 to 4. Therefore, this “other matters” will be omitted by referring to the contents described above.

  The rotary adhesive cleaner according to the present invention illustrated in FIGS. 6 and 7 corresponds to the third embodiment. Furthermore, the rotary adhesive cleaner 41 illustrated in FIGS. 6 and 7 is the one in the first embodiment (FIG. 4), which is combined with a handle 61 for a handle.

  In the rotary adhesive cleaner 41 of FIGS. 6 and 7, the handle 61 for the handle shown here is merely an example. The handle 61 for the handle in this case includes a handle member 62, a pair of fitting members 65 and 67, and a plurality of elastic members 68.

  As is apparent with reference to FIGS. 6 and 7, the handle member 62 is of a bent type having a grip portion 63 at one end and a support shaft portion 64 at the other end. It is in a right angle relationship. The handle member 62 is made of a thick wire (elongated metal rod) having a diameter of 4 mm or more, for example, and is bent into a required shape. The grip portion 63 on one end side of the handle member 62 is formed by placing a grip member made of rubber or synthetic resin on one end portion of the handle member 62. On the other hand, a pair of fitting members 65 and 67 are attached to the support shaft portion 64 of the handle member 62 at an inter-axis distance. Both the fitting members 65 and 67 are also made of rubber or synthetic resin. One of the fitting members 65 has a flange-like stopper 66 formed on the outer peripheral portion of the outer end surface. Both fitting members 65 and 67 can be fitted into the support shaft 51 except for the stopper 66. Therefore, the outer diameters of the fitting members 65 and 67 except for the stopper 66 are slightly smaller than the inner diameter of the support shaft 51, and the outer peripheral surfaces of the fitting members 65 and 67 fit the inner peripheral surface of the support shaft 51. To do. The plurality of elastic members 68 are made of an elastic material made of metal or synthetic resin, and each elastic member 68 is bent in a gentle arc. Each elastic member 68 is constructed over both the fitting members 65 and 67 by inserting and fixing both end portions thereof to the inner end surfaces of the fitting members 65 and 67. More specifically, the respective resilient members 68 installed over both the fitting members 65 and 67 are arranged at equal intervals in the circumferential direction to form a radial arrangement state, and the respective bent shapes are outward. It has a form that swells. In this case, the maximum outer diameter portion of each bulge member bulge portion formed by each bulge member 68 bent outward is larger than the inner diameter of the support shaft 51. It is approximately about 2 mm to 6 mm above the diameter.

  In the rotary adhesive cleaner 41 illustrated in FIGS. 6 and 7, the handle 61 for the handle is supported by both fitting members 65 and 67 on the support shaft portion 64 side of the handle member 62 and the respective resilient members 68. By being inserted and mounted in the shaft 51, it is combined with the adhesive cleaner roller 11 to thereby constitute the rotary adhesive cleaner 41 of this embodiment. More specifically, when the handle is mounted, the handle predetermined portion is fitted into the support shaft 51 with the fitting member 67 side at the forefront, and the stopper 66 of the fit member 65 contacts the one end surface of the support shaft 51. The handle installation is completed by touching. In this handle mounted state, the support shaft 51 and the fitting members 65 and 67 located in both ends of the support shaft 51 are fitted so as to be rotatable relative to each other, and the elastic members 68 are elastically deformed. It is in pressure contact with the inner peripheral surface of the support shaft 51. Thus, in the case of the handle 61 combined with the adhesive cleaner roller 11, each resilient member 68 is in pressure contact with the inner peripheral surface of the support shaft 51, and a static frictional force is generated at the contact location. The combined state of the roller 11 and the handle 61 is maintained. Further, the handle 61 can be pulled out of the support shaft 51 by applying a pulling force exceeding the static frictional force, and is thereby detached from the adhesive cleaner roller 11. As is clear from this, the handle 61 for the handle is detachable.

  The handle 61 illustrated in FIGS. 6 and 7 is known or well known and may be commercially available. As a detachable handle of the same type as the handle 61, a handle having a handle longer than the handle 61 is known or well known. In addition to these, a handle in which the portions fitted into both ends of the support shaft 51 are bifurcated is also known or well known, and this can also be applied as the handle of the rotary adhesive cleaner 41. Therefore, any handle that can be applied to the rotary adhesive cleaner 41 can be used as long as the support shaft 51 can be supported at both ends rotatably.

  Some of the handles 61 described above are also fixedly attached to the support shaft 51. One example thereof is that a bearing portion having a bifurcated branch portion is provided, and both end portions of the support shaft 51 are rotatably supported via the two bearing portions. Such types of handles are well known not only in rotary adhesive cleaners but also in painting rollers and others.

  Each rotary adhesive cleaner 41 described with reference to FIGS. 4 to 7 is used as follows.

  In the case of the rotary adhesive cleaner 41 illustrated in FIG. 4, for example, this constitutes a cleaner device (not shown) having a structure like a roller conveyor arranged in parallel, and each rotary adhesive cleaner 41. Is rotated by driving means and transmission means to clean the object to be cleaned. As a specific object to be cleaned at that time, planar products such as plates and sheets can be raised. The object to be cleaned moves in the rotation direction of the rotary adhesive cleaner 41 while being pressed onto each rotary adhesive cleaner 41 rotating in a parallel arrangement state. In the case of a cleaning object that moves in this manner, dust and dirt adhering to the surface of the object are transferred to the adhesive film layer 31 side of each rotary adhesive cleaner 41. Will be converted. Among the items to be cleaned, various primary processed products or high-order processed products handled in production factories and others are included.

  Similarly to the above, the rotary adhesive cleaner 41 illustrated in FIG. 5 is also used in a mode in which a large number of them are arranged in parallel to form a cleaner device (not shown) having a structure like a roller conveyor. Therefore, also in the example of using the rotary adhesive cleaner 41 in this way, the object to be cleaned having a planar shape such as a plate shape or a sheet shape is cleaned by removing dust and dirt in the same manner as described above.

  In the case of the rotary adhesive cleaner 41 illustrated in FIGS. 6 and 7, the user holds the handle 61 and presses the adhesive cleaner roller 11 against the surface (surface to be cleaned) of the object to be cleaned, and the adhesive The required cleaning is performed while rolling the cleaner roller 11 on the surface of the object to be cleaned. Even during this cleaning operation, dust and dirt adhering to the surface of the object to be cleaned adhere and transfer to the adhesive film layer 31 side of each rotary adhesive cleaner 41, so that the object to be cleaned is used as intended. Will be cleaned. Examples of daily cleaning using the rotary adhesive cleaner 41 illustrated in FIGS. 6 and 7 include floor cleaning, table cleaning, wall surface dirt removal, hair loss treatment of pet animals, and the like.

  The rotary adhesive cleaner 41 illustrated in FIGS. 6 and 7 also has an example in which dust or the like removed by the cleaner 41 is transferred (also referred to as transfer) to the adhesive pad. As is well known, the rotary adhesive cleaner 41 is utilized when visually inspecting a cleaning object traveling on a line in a factory or the like. The contents of the work are as follows. The worker holds the rotary adhesive cleaner 41 and stands at a predetermined position on the line. When the dust on the cleaning target traveling in line is found, the operator presses the rotary adhesive cleaner 41 on the dust and sticks the dust with the adhesive film layer 31 of the adhesive cleaner roller 11. Following this operation, the worker presses and rolls the adhesive cleaner roller 11 against the adhesive pad near the line, and transfers the dust adhering to the adhesive film layer 31 side to the adhesive pad side. As a result, the adhesive cleaner roller 11 returns to the initial clean state with no dust adhering, so that the rotary adhesive cleaner 41 can be provided for the next dust trapping. This series of operations by workers is performed quickly. In addition, since the adhesive cleaner roller 11 is always in a clean state when dust is trapped, dust contamination from the adhesive cleaner roller 11 to the object to be cleaned is unlikely to occur.

  As the pressure-sensitive adhesive pad in the above use example, a multi-layered pressure-sensitive adhesive sheet is used. In the case of this adhesive pad, every time the adhesive sheet reaches a use limit due to dirt, it is peeled off and a new adhesive sheet is prepared. About the adhesive film layer 31 of the adhesive cleaner roller 11 and the adhesive sheet of the adhesive pad, the adhesive force of the adhesive sheet exceeds that of the adhesive film layer 31. Therefore, the dust trapped by the adhesive film layer 31 in the above is transferred to the adhesive sheet (adhesive pad) side.

  The adhesive cleaner roller and the rotary adhesive cleaner 41 according to the present invention can be used in a wide range of fields such as home use, business use, and industrial use.
