Technical Field

The present invention relates to a sliding device for supplying or discharging a sliding treatment object to or from a surface of a sliding object.

Background

In recent years, in various applications, a filler-containing film in which a predetermined filler is put in a concave portion on a film surface is required. For example, an electrode paste is supplied to a predetermined pattern of recesses formed in a film substrate, and excess paste is removed by an erasing device to produce a biosensor electrode (patent document 1). In this case, the blade is used for supplying the paste to the concave portion and for wiping off the excess paste.

On the other hand, in a printing apparatus, a squeegee is generally used to spread ink over a mask plate, and the following is proposed: in order to make the print density uniform, the squeegee is reciprocated in a direction (x direction) orthogonal to the longitudinal direction of the squeegee and also reciprocated in the longitudinal direction (y direction) of the squeegee, thereby moving the squeegee in a zigzag shape with respect to the mask plate (patent document 2).

As such, from the past, when supplying a filler to the recessed portions or hole portions of the substrate surface and removing the excess filler from the substrate surface, a blade or a squeegee is used.

Disclosure of Invention

Problems to be solved by the invention

When supplying a filler to an embossed body having a predetermined pattern of recessed portions formed on the surface thereof, it is conceivable to move a squeegee in a zigzag manner as described in patent document 2 so that the supply is performed uniformly. However, when the squeegee is moved in a zigzag manner, it is difficult to sufficiently increase the ratio (%) of the number of recessed portions (N1) into which the filler has entered to the number of recessed portions (N0) on the surface of the embossed body (100 × N1/N0) on both sides of the surface of the embossed body where the moving direction of the squeegee changes. That is, a portion where the filler is unevenly supplied is generated. On the other hand, if the input amount of the filler is increased, the amount of the filler which becomes wasted increases, and the fillers excessively rub against each other, so there is a fear of damage, deformation, or the like of the filler.

To solve the above problems of the prior art, the present invention has the following problems: in the case where an object having a predetermined pattern of recesses formed on the surface thereof, such as an embossed body, is used as a sliding object and a sliding treatment material such as a filler is supplied to the recesses on the surface of the sliding object, the sliding object is uniformly supplied to the entire recess of the region where the sliding object is subjected to the supply processing of the sliding object (hereinafter referred to as the sliding object region), and can remove the redundant sliding processed object from the sliding object, and reduce the redundant sliding processed object finally removed from the sliding object in the sliding processed object supplied to the sliding object, prevent the damage or deformation of the sliding processed object caused by the excessive collision or friction between the sliding processed objects, and in addition, when the sliding object is supplied with the sliding object on a flat surface, the sliding object can be uniformly supplied to the entire surface of the sliding object region.

Further, in the present invention, supplying the sliding processed object to the surface of the sliding object includes: when the object to be slid is an embossed body and the object to be slid is a granular object, the granular object is uniformly put into the recessed portion on the surface of the embossed body. In addition, when the sliding treatment object is a liquid object, the method further includes forming a coating film of the liquid object on the surface of the sliding object with a uniform thickness. In addition, in the present invention, the removing of the sliding processed object from the surface of the sliding object includes: when the particulate matter adheres to the sliding object, the liquid material is supplied as the sliding object to remove the particulate matter.

Means for solving the problems

The present inventors have completed the present invention in view of the following: when a slide portion having a plurality of slide bodies each having a flat working surface is used for the slide object so that the slide body is moved in the first direction and the slide portion is also moved in the second direction, the amount of relative movement of the slide object during the slide process is increased, the slide object is uniformly supplied with the slide processed object, and the excess slide processed object is removed from the slide object, whereby the surface of the slide object can be cleaned without supplying the slide processed object.

That is, the present invention provides a sliding device including:

a sliding section provided with a plurality of sliding bodies having flat operating surfaces; and

a drive mechanism for regularly moving the sliding part relative to the sliding object in parallel with the action surface of the sliding body and in a direction different from the moving direction of the sliding body while regularly moving the sliding body relative to the sliding object in parallel with the action surface,

the sliding body of the sliding part is used to perform sliding treatment on the surface of the sliding object.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the slide device of the present invention, since the slide body is moved in the first direction with respect to the object to be slid and the slide portion provided with the slide body is moved in the second direction at the same time, the amount of movement per unit time of an arbitrary point in the operating surface of the slide body with respect to the object to be slid is increased and the amount of movement of the object to be slid by the slide body on the object to be slid is also increased, as compared with the case where the slide body is moved only in either direction. Further, since the slide body does not come into line contact with the object to be slid like a squeegee, but has a flat surface as an acting surface with respect to the object to be slid, if the slide-processed object is supplied to the slide device, the slide-processed object is not only pushed by the side surface of the slide body and moved on the object to be slid, but also captured and moved by the acting surface as the bottom surface of the slide body. Therefore, according to the slide device of the present invention, the amount and the moving amount of the slide processing object itself which is moved on the slide object by the slide body are increased. Therefore, the sliding processing object can be uniformly supplied to the sliding target region, and the excessive sliding processing object can be excluded from the sliding target region, so that the supply amount of the sliding processing object required for processing the sliding processing object by the sliding processing object can be reduced.

Thus, for example, in the case where the embossed body is used as the object to be slid and the filler is used as the object to be slid, the filler can be uniformly put into the recessed portions on the surface of the embossed body, the filler that has unnecessarily adhered to the portions other than the recessed portions can be eliminated, and the amount of the filler to be put into the embossed body, which is required for uniformly putting the filler into the recessed portions of the embossed body, can be reduced.

Further, for example, when a liquid material is supplied as the sliding treatment object, the excess attached matter on the sliding object can be removed by wiping the sliding object using the liquid material. Even when the sliding object is subjected to sliding processing without supplying the sliding object, the surface of the sliding object can be cleaned.

Detailed Description

Hereinafter, the sliding device according to the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or equivalent constituent elements.

< brief summary of sliding device >

Fig. 1 is a schematic side view of a sliding device 1 according to an embodiment of the present invention. The sliding device 1 includes a sliding portion 4, and the sliding portion 4 has an embossed body W having a concave portion on a surface thereof as a sliding object and a filler F as a sliding processed object. Preferably, the sliding portions 4 are arranged in parallel in the conveyance direction (arrow Z) of the embossed body W as needed.

The slide portion 4 is provided with a plurality of sliders 6 having a flat operating surface 6A, and the positional relationship thereof is adjusted so that the operating surface 6A abuts against the surface of the embossed body W.

The slide device 1 includes, as a drive mechanism for moving the slider 6 in a first direction and simultaneously moving the slide portion 4 in a second direction different from the first direction: a first drive mechanism 20 that regularly moves the slider 6 in parallel with the operation surface 6A; and a second drive mechanism 30 that regularly moves the entire slide 4 including the plurality of slides 6 in parallel with the operation surface 6A while the slides 6 are moved by the first drive mechanism 20. The drive source of the first drive mechanism and the drive source of the second drive mechanism may be common or separate. In the slide device according to the present invention, an integrated drive mechanism may be provided as the drive mechanism for moving the slide body and the slide portion as described above.

The slide device 1 includes a treatment material feeding means for feeding the filler F to a predetermined portion of the surface W2 of the embossed body W, and may include a scraper for spreading the filler F on the embossed body W to some extent before the filler F fed to the embossed body W is spread by the slide portion 4, as needed.

As will be described later, the fillers F are supplied to the embossed body W in the same manner by the slide body 6 that is moved by the first drive mechanism 20 and the second drive mechanism 30, the fillers enter the recessed portions of the embossed body W, and the excess fillers F are removed from the surface of the embossed body W other than the recessed portions. Alternatively, the supplied filler F enters the concave portion W3 of the embossed body at a high ratio, and the excluded filler F is not generated or becomes slightly small. Therefore, the present invention is useful not only as a device for filling the filling material into the recessed portions of the embossed body, but also as a device for removing excess filling material present in portions other than the recessed portions, and can be used when the removed filling material is recovered and reused.

< sliding object >

In the present invention, the sliding object W can be various plates, films, three-dimensional objects, and the like having a surface parallel to the operation surface 6A of the sliding body 6, and the sliding device 1 can be provided with a support mechanism or a conveyance mechanism for the sliding object W as appropriate depending on the kind, form, and the like of the sliding object. For example, when the object to be slid is a plate, a film, or the like, the device may include a base for supporting the object, a driving device serving as a conveying mechanism, a winding device, or the like.

The sliding device 1 of the embodiment shown in fig. 1 and 2 has a plate-shaped embossed body as a sliding object W. As shown in fig. 4A and 4B, the embossed body W has a plurality of recesses W3 on the front surface W2 of the long embossed body W1. Alternatively, the embossed body W may be formed with surface irregularities to hold the filler F at a predetermined position.

The embossed body W can be formed of a plastic or curable resin, metal, or the like by utilizing its physical properties or functions. The thickness, width and length of the embossed body W are not particularly limited. For example, the width of the emboss W (the length in the direction orthogonal to the conveying direction) may be 10 cm or more, 30 cm or more, or 50 cm or more, and may be 10m or less, 5 m or less, or 2 m or less depending on the application of the embossed body after the sliding treatment, regardless of whether the embossed body W is in a plate shape or a film shape. When the embossed body W is plate-shaped, the length (length in the conveying direction) thereof may be, for example, less than 1 m, or 1 m or more, or 5 m or more. When the embossed body W is film-shaped, the length may be 5 m or more, or 100 m or more. The upper limit of the length is usually 5000 m or less, 1000 m or less, or 300 m or less in the case of using the embossed body as a wound material (an object wound around a core) from the viewpoint of handling.

The thickness of the embossed body W is not particularly limited as long as the embossed body W is conveyed to the slide 4 by the conveying means 3, and the sliding process can be performed without trouble while the embossed body W is brought into contact with the slide 6 or the distance therebetween is maintained at a predetermined value.

The material of the embossed body W is not limited to resin. The material may be one having a surface of glass or metal processed, or may have a laminated structure of a plurality of materials selected from various resins, glass, and metals. The layers constituting the embossed body W or the entire embossed body may be rigid, flexible or elastic, or may exhibit adhesiveness at room temperature (25 ℃. + -. 15 ℃). Therefore, as the resin material for forming the embossed body, a thermoplastic resin or a thermosetting resin can be appropriately selected from organic materials such as chemical plant materials of the handbook of chemistry (first edition, applied article), the handbook of physico-chemistry (4 th edition), general-purpose plastics, engineering plastics, and special engineering plastics described in the engineering plastics technical association (http:// enpla. Various general materials can be used as the metal material. In general, when filling a filler into an embossed body by a sliding process, if the embossed body W has flexibility or adhesiveness, it becomes difficult to fill the filler uniformly into the entire sliding target region of the embossed body, but according to the present invention, the embossed body W can be a sliding target even if it has flexibility or adhesiveness, regardless of whether it is a single-layered body or a laminated body.

The embossed body W has a laminated structure of a plurality of layersIn the case of manufacturing, an adhesive layer or a resin layer similar thereto may be interposed between a layer having surface irregularities such as the recessed portions W3 and a layer to be a base thereof. For example, the layer having surface irregularities may be a rigid layer, an elastic body or a plastic body, or a viscous or viscoelastic body having high viscosity capable of retaining the surface irregularities in shape at room temperature when the temperature during the sliding treatment is room temperature. The adhesive layer or a layer similar thereto located under the layer having surface irregularities can be a layer having a high viscosity equal to or higher than that of the layer having surface irregularities, can be a layer having a lower viscosity than that of the layer having surface irregularities, and can be a liquid or a viscous body similar thereto. Thus, as an example, the viscosity of the layer under the layer having surface irregularities is at 0.1 Pa ･ s-10 at normal temperature⁴ Pa ･ s. The value is measured by a known vibration viscometer, a rotational viscometer, or a viscoelasticity measuring apparatus (for example, a rheometer manufactured by a TA instrument). In the present invention, even if the embossed body W is a laminate of layers having various materials and physical properties as described above, the filler can be accommodated in the concave portion without applying an excessive load such as deformation or damage to the filler.

The processing method for forming surface irregularities such as the recessed portions W3 on the surface of the embossed body W is not particularly limited as long as it is a method capable of controlling the dimensions in μm units. Depending on the type of material constituting the embossed body W, techniques such as cutting, punching, etching, lamination of porous layers, and printing can be used. The unevenness previously provided on the master may be transferred to a layer on the surface of the embossed body W. For example, if the surface of the embossed body W is made of metal, the surface unevenness can be formed by cutting. When the surface irregularities of the embossed body W are formed of a resin, the surface irregularities may be formed by various printing methods, or a layer having surface irregularities or holes may be laminated.

The shape and depth of the opening surface of the recess W3 formed in the embossed body W1 are determined in accordance with the use of the embossed body, the type and size of the filler F put into the recess W3, and the like. For example, as shown in fig. 5 and 6, the diameter and depth of one recess W3 can be set to be the diameter and depth of just entering one spherical filler F. More specifically, in order to allow one spherical body constituting the filler F to enter one recess W3, the particle diameter of the sliding processed object F may be 200 μm or less for a lower limit of the visible light wavelength or more, preferably 1 μm or more, more preferably 2 μm or more, and may be 30 μm or less, more preferably 20 μm or less for an upper limit of the particle diameter, and in this case, the opening diameter of the recess W3 may be preferably 1 time or more and 1.5 times or less, more preferably 1 time or more and 1.2 times or less of the particle diameter.

In order to allow one ball to enter one recess W3, the opening shape of the recess W3 may or may not be identical to the shape of the ball. It is preferable that there is a similarity or the like in the opening shape of the recess W3 and the shape of the ball. For example, when the opening shape of the recess W3 is a rectangle having sides with a ratio of 1:1.2, if the maximum diameter of the ball is the same as 1 which is the short side of the recess W3, the ball is accommodated with a suitable margin. In addition, when the material of the embossed body W1 is a resin or the like and is a material that can allow deformation, the opening shape of the recess W3 can be accommodated even if the opening shape matches the shape of the ball and the size is doubled.

On the other hand, the opening diameter of the recess W3 may be larger than the particle diameter of one filler F, and a plurality of fillers may be accommodated in one recess W3. For example, when the fine filler is attached to the surface of the filler F in advance, the filler F enters the recessed portion W3 together with the fine filler on the surface. In this case, the above-described relationship applies to the size and the opening diameter of the filler F to which the fine filler is attached.

The arrangement pattern of the recesses W3 of the embossed body W is not particularly limited. For example, the pattern can be a regular array having a predetermined repeating pattern. More specifically, for example, as shown in fig. 4A, the lattice can be a hexagonal lattice. Further, the lattice may be arranged as a square lattice, a rectangular lattice, an orthorhombic lattice, or the like. Further, a plurality of different lattice combinations may be arranged. The filler may be arranged in parallel at a predetermined interval in a filler row in which the fillers are linearly arranged at a predetermined interval. Further, the repetitive pattern may be continuously present, or a region in which the repetitive pattern is formed may be repeated with an interval. When there is a fixed repeating pattern, if there is a mark or a slight change (for example, the shape of the opening is not so different as to affect the storage of the filler) distinguished from it, it may be preferable from the viewpoint of product management.

In the present invention, the sliding object is not limited to the sliding object having the surface irregularities described above, and may be a sliding object having a fine surface, a flat surface, a surface which is easily damaged, or the like.

< sliding treated article >

The sliding processed object used in the present invention is appropriately selected from fillers such as powder and granules, liquids such as solvents, and the like, depending on the application of the sliding object to which the sliding processed object is supplied. The surface of the sliding object can be cleaned by using the liquid as the sliding object. In the case of using a filler as the sliding treatment object, the filler may be mixed with a liquid, but is preferably not a paste.

In the sliding device 1 of the embodiment shown in fig. 1, the filler F is used as the sliding treatment substance. When the filler F is used as the sliding treatment object, the filler may contain one or more kinds of powders and granules. The powders and granules may be independent of each other or may be a polymerized aggregate. The filler F may be a filler having a smaller filler attached to the surface thereof, or a filler having the surface covered with a smaller filler. The aggregate may be crushed by the sliding body 6, or the aggregate may be supplied as it is if the recessed portion W3 is of a size capable of accommodating the aggregate.

The raw material for forming the filler F can be appropriately selected depending on the use of the embossed body W to which the filler F is supplied or the article produced from the embossed body W to which the filler F is supplied, and for example, can be used as a composite filler composed of an inorganic filler (metal, metal oxide, metal nitride, or the like), an organic filler (resin, rubber, or the like), or an organic-inorganic composite material composed of an organic material and an inorganic material. In the composite filler, an organic material and an inorganic material may be mixed together, or the surface of the organic material may be covered with the inorganic material, or the surface of the inorganic material may be covered with the organic material. The organic material and the inorganic material may be present in a composite form. In addition, two or more fillers can be used in combination as the filler F according to need. Further, the surface of the filler F may be smooth or may not be smooth. For example, minute bumps may be formed.

More specifically, when the embossed body W is used as an optical film or a matte film, a silica filler, a titanium oxide filler, a styrene filler, an acrylic filler (アクリルフィラー), a melamine filler, various titanates, or the like can be used as the filler F. The filler F may be the same material as the pigment in order to impart light-blocking properties or color to the embossed body.

When the embossed body W is used as a film for capacitors, titanium oxide, magnesium titanate, zinc titanate, bismuth titanate, lanthanum oxide, calcium titanate, strontium titanate, barium zirconate titanate, lead zirconate titanate, a mixture thereof, or the like can be used as the filler F.

When the embossed body W is used as an adhesive film, a polymer rubber, a silicone rubber, or the like can be contained as the filler F. In this case, for example, the filler F can be made to function as a gasket.

The filler F may be an electrically insulating material (insulator), may be an electrically conductive material (conductor) in contrast to the electrically insulating material, or may be a material showing the properties of a semiconductor. As the filler F, two or more species having different or opposite effects may be used in combination.

In the sliding device of the present embodiment, the filler F is dry-stored in a predetermined portion (for example, an opening portion of the recessed portion W3) defined by the surface irregularities of the embossed body W. In this regard, the filler F is distinguished from an object in which particles such as a pigment or a solder are mixed with a liquid or paste resin binder, such as a paint or a solder paste for screen printing. Further, the sliding device of the present invention differs from a polishing device for a sliding object using powder in the following points: the filler and the sliding object (embossed body) W are not damaged. Therefore, according to the present invention, at least one of the filler and the object to be slid can be reused, and the reused filler can be supplied to the recessed portion of the embossed body.

The application of the embossed body W to which the filler F is supplied is not limited to the above-described example, and various kinds of embossed bodies can be handled in the slide device 1.

The size of the filler F can be determined as appropriate depending on the use of the embossed body W to which the filler F is supplied. For example, in order to uniformly enter the pocket W3 of the embossed body W, it is preferable that the pocket W3 of the embossed body W be one pocket of the filler F. On the other hand, the filler may be inserted into one recess W3 as a plurality of fillers, if necessary.

The size of the filler can be measured by a general particle size distribution measuring apparatus, and the average particle diameter can also be determined by using a particle size distribution measuring apparatus. As an example of the particle size distribution measuring apparatus, a wet flow type particle size/shape analyzer FPIA-3000 (Malvern) may be mentioned. On the other hand, the method of determining the particle diameter of the filler after supplying the filler to the recessed portion W3 of the embossed body W can be determined by observing the filler in a plan view or a cross-sectional view with an optical microscope such as a metal microscope or an electron microscope such as SEM. In this case, it is preferable that the number of samples for measuring the particle diameter of the filler is 200 or more. In addition, when the shape of the filler is not spherical, the maximum length or the diameter of the pseudo-spherical shape can be used as the particle diameter of the filler.

The filler preferably has a small variation in particle diameter in order to uniformly penetrate into a predetermined portion defined by surface irregularities such as the recessed portion W3 of the embossed body W, and particularly, the CV value (standard deviation/average) of the variation in particle diameter of the filler is preferably 20% or less, more preferably 10% or less, and further preferably 5% or less.

The variation in the particle size of the filler can be determined using the wet flow particle size/shape analyzer FPIA-3000 (malvern). In this case, if the number of fillers is measured to be one thousand or more, preferably three thousand or more, and more preferably five thousand or more, the variation of the filler alone can be accurately grasped. When the filler is disposed on the embossed body, it can be determined from a plan view image or a cross-sectional image in the same manner as the measurement of the average particle diameter.

The shape of the filler can be appropriately selected from spherical, ellipsoidal, columnar, needle-like, a combination thereof, and the like, depending on the use of the embossed body. The filler is preferably spherical, and particularly preferably substantially spherical, in view of uniformly and accurately entering the recess W3 of the embossed body W.

Here, the substantially regular sphere means that the regular sphericity calculated by the following equation is 70 to 100.

Positive sphericity = [ 1- (So-Si)/So ] X100

In the above formula, So is the area of the circumscribed circle of the filler in a plan view of the filler, and Si is the area of the inscribed circle of the filler in a plan view of the filler.

In this calculation method, it is preferable that images of the filler are taken in a plan view and a cross-sectional view of the embossed body into which the filler has entered, and in each image, the area of a circumscribed circle and the area of an inscribed circle of one hundred or more (preferably two hundred or more) arbitrary fillers are measured, and the average value of the circumscribed circle area and the average value of the inscribed circle area are determined as So and Si described above. In both of the plan view and the cross-sectional view, the positive sphericity is preferably within the above range. The difference in positive sphericity between the plan view and the cross-sectional view is preferably within 20, and more preferably within 10. The sphericity of the filler monomer can also be determined using a wet flow particle size/shape analyzer FPIA-3000 (malvern).

< means for conveying sliding object >

The sliding device 1 of the embodiment shown in fig. 1 has: a support table 2 that supports an embossed body W as a sliding object; and a conveying means 3 for conveying the embossed body W so that the front surface W2 of the embossed body W becomes parallel to the action surface 6A of the slider 6.

The support table 2 has a flat upper surface on which the embossed body W is placed as shown in the figure, and the surface of the embossed body W during conveyance is brought into contact with the operating surface 6A of the slider 6 or opposed to the operating surface with a predetermined gap.

As shown in fig. 1, the conveying means 3 conveys the plate-like embossed body placed on the support table 2 by a roller conveyor or the like in a single sheet manner at least from the position where the filler F is supplied to the embossed body W to the position where the treatment by the slide 4 is completed. In this case, the plate-like embossed body may be intermittently conveyed. On the other hand, when the embossed body is formed into a roll in a long film form, the embossed body may be conveyed in a roll-to-roll manner by using a supply roll and a take-up roll.

As a treatment material feeding means (not shown) for feeding the filler F to a predetermined portion on the embossed body W, a treatment material feeding means capable of adjusting the feeding amount of the filler F to the embossed body W per unit time is preferable.

< scraper >

In the present invention, the scraper is provided as needed according to the application of the sliding device, the form of the sliding processed object F, the input pattern of the sliding processed object F by the processed object input means, and the like. For example, when the filler is fed to the central portion of the embossed body W without being fed to the entire width of the embossed body W by the processed object feeding means, the scraper can be provided between the feeding position and the sliding portion 4.

The material of the blade may be, for example, rubber, engineering plastic, metal, fiber, or the like, and the hardness in the case of a non-metal material may be Shore a 5-100. Further, the length of the blade in the conveyance direction of the embossed body can be set to 1 to 50 mm, the roughness of the tip surface of the blade can be set to Ra0.05 to 100, and the pressing force applied to the blade can be set to 0.001 to 1 kgf/cm.

On the other hand, when the sliding device of the present invention is used to eliminate or wipe off an unnecessary sliding treatment object adhering to a sliding object, the blade is not necessary.

< sliding part >

The sliding portion 4 includes a sliding body 6 having a flat operating surface 6A. As an example, the slider 6 can have a cylindrical outer shape as shown in fig. 3. The slider 6 shown in the figure is formed of a surface material 6B constituting a side surface and an operation surface 6A as a bottom surface, an elastic material 6C occupying the inside of the surface material 6B, and an upper surface material 6D. In the present invention, the shape of the operation surface 6A of the slider 6 is not limited to a circle, and may be a polygon. In order to equalize the load applied to the filler, it is preferable that the corners 6A between the bottom surface and the side surfaces of the acting surface 6A be rounded, and the filler around the sliding body 6 smoothly enter the acting surface 6A and the like.

In the slide device 1 shown in fig. 1, the acting surface 6A of the slide body 6 is in contact with the surface of the embossed body W, but in the present invention, the distance between the acting surface 6A and the object to be slid can be appropriately adjusted.

The surface material 6B is a film or a fibrous body made of a fluororesin or the like and formed in a bottomed cylindrical shape, and its circular bottom surface is a flat working surface 6A. The preferable range of the coefficient of dynamic friction of the surface material 6B on the surface of the sliding object is preferably 25 or less, more preferably 2 or less, and preferably 1 or more, because the ease of movement of the sliding object is influenced by the combination of the properties of the sliding object such as the material and size of the filler and the properties of the sliding object such as the material and size of the embossed body. Further, the coefficient of dynamic friction can be measured at a load of 100 g and a moving speed of 1000 mm/min using a surface property measuring machine (type: 14 (HEIDON)) manufactured by New eastern science, Inc. It can also be measured at a moving speed of 100 mm/min in accordance with JIS K7125.

In the sliding device 1 shown in fig. 1, a sponge is used as the elastic member 6C (fig. 3) of the slider 6. The elastic member 6C occupies the inside of the slider 6, and thus it is possible to prevent the surface from being damaged by deformation, cracking, peeling, damage, and the like in the filler F sandwiched between the acting surface 6A and the embossed body W, and the like, by applying an unnecessary force to the filler F. In the present invention, a spring member for biasing the surface material 6B toward the action surface 6A may be provided as the elastic member 6C.

On the other hand, the upper surface material 6D is connected to the first driving mechanism 20.

In the sliding apparatus of the present invention, one sliding portion 4 may be provided, or a plurality of sliding portions 4 may be provided, but in order to improve ductility of the sliding processed object in the sliding object, it is preferable to provide a plurality of sliding portions in parallel in the conveying direction of the sliding object, and for example, two sliding portions 4 may be provided in parallel in the conveying direction of the embossed body W. In this case, the distance between the adjacent sliding portions 4 can be appropriately adjusted according to the area to be spread in the sliding object, the processing speed, and the like.

In the case where a plurality of sliders 6 are provided in each of the sliders 4, for example, three to six sliders 6 may be provided in a triangular lattice shape, a square lattice shape, a radial shape, or the like in one slider 4. In this case, the distance between the adjacent sliders 6 may be adjusted according to the material of the filler, and if the distance is long, the load applied to the filler becomes discontinuous, and therefore, preferably, if the distance is short, the elongation becomes continuous, and thus, an improvement in the elongation is expected. When importance is attached to the improvement of ductility, the distance between the adjacent sliders 6 is preferably short, and the closest distance therebetween can be set to, for example, preferably 2 to 500 mm, more preferably 2 to 300 mm, and still more preferably 10 to 50 mm.

In the present invention, the pattern of movement of the slide body 6 by the first drive mechanism 20 and the pattern of movement of the slide portion 4 by the second drive mechanism 30 are each a pattern in which the direction of movement is changed regularly, and a smoothly and regularly changed pattern is particularly preferable. For example, the motion can be a circular motion or a circular motion on various smoothly closed curves such as a circle, an ellipse, a lemniscate, a cycloid, and a straight-lobe curve. These movement patterns can be configured using a cam mechanism, a gear mechanism, a rotation mechanism, and the like. In the case where the slide body 6 and the slide portion 4 adopt any one of the movement patterns, as shown in fig. 2, any point P in the action surface 6A of the slide body is moved at a speed Vx on a trajectory of a broken line in the action surface 6A by the first drive mechanism 20, and is moved at a speed Vy on a trajectory of a two-dot chain line in a plane including the action surface 6A by the second drive mechanism 30, so that a movement amount per unit time of the point P on the surface of the slide object W becomes larger than the case where the point P is moved by any one of the first drive mechanism 20 and the second drive mechanism 30. Therefore, the slide-processed object F can be sufficiently spread over the slide-target object W. In particular, in the case where the point P makes a linear reciprocating motion, the sliding processed object is not stretched at a portion that is sharply bent in the moving direction, and the filler F is ejected from the sliding target region and is wastefully consumed or causes contamination of the surroundings, but if the moving direction of the point P is smoothly changed in a curve, the ductility is further improved, and the filler F can be prevented from being ejected from the sliding target region. Further, the moving amount of the point P with respect to the sliding object W is further increased by the conveying means 3. Therefore, the ductility of the sliding processed object F in the sliding object W is further improved. On the other hand, if the moving amount of the point P is too small, the sliding object F cannot be sufficiently extended on the sliding object W. Further, when the moving speed of the conveying means 3 is too high, the sliding processing time cannot be sufficiently secured, and the ductility is also reduced. Therefore, the moving speed of the sliding object W by the conveying means 3 is preferably determined appropriately according to the moving speed of the slider 6 and the sliding portion 4.

As described above, the movement amount per unit time of the arbitrary point P in the working surface 6A by the action of the first drive mechanism 20 and the second drive mechanism 30 becomes large, which means that the relative movement amount of the point in the working surface 6A corresponding to the reference point in the sliding object W becomes large. Therefore, according to the present invention, when the sliding processed object F is uniformly supplied to the sliding object W and the sliding object W is the embossed body, the ratio of the sliding processed object F entering the concave portion of the sliding object W becomes high, and the excessive sliding processed object F can be excluded from the sliding object W.

< uses of sliding device >

The sliding device of the present invention can be used as follows: a device for supplying a filler in a dry manner to a concave portion of a sliding object W having a concave portion such as an embossed body, a device for removing an excess filler from the embossed body to which the filler has been supplied, a device for supplying a liquid substance such as a solvent to a flat surface of an arbitrary sliding object W and wiping the same, a device for cleaning the surface of the sliding object W, and the like.

< method of using sliding device >

As a method of using the sliding device of the present invention, the sliding object W and the sliding processed object F are appropriately selected and set in the sliding device according to the application. In addition, the driving speeds of the first driving mechanism 20 and the second driving mechanism 30 are adjusted. Further, when the sliding object W is conveyed by the conveying means 3 during the sliding process using the sliding device 1, the conveying speed is also adjusted.

For example, when the embossed body W is a sliding target, the filler F is a sliding treatment, and the filler F is uniformly put into the embossed body concave portions W3 regularly arranged on the surface of the embossed body W, first, the embossed body W is placed on the support table 2, the support table 2 is set on the conveying means 3, and the conveying means 3, the first drive mechanism 20 of the slide 4, and the second drive mechanism 30 are driven at predetermined speeds, respectively. When the embossed body W is a film, it is preferable to use a winding mechanism or the like as described above.

Subsequently, the filler F is supplied to a specific portion of the embossed body W at a predetermined input speed. The amount of the filler F to be supplied can be determined according to the purpose of the sliding treatment, such as filling the filler F to some% of the number of the recesses W3 of the embossed body W, but generally, the number of the fillers to be charged is preferably 250% or less, more preferably 200% or less, and still more preferably 150% or less, with respect to the number of the recesses of the embossed body. The lower limit of the supply amount may be less than 100%. This is because the number of fillers may be smaller than the number of recesses W3 for the purpose of the sliding process. The number of concave portions of the embossed body can be determined in the same manner as the number of concave portions in the remaining ratio described later.

When a scraper is provided downstream of the input portion as needed, the filler F is spread to some extent on the embossed body W by the scraper.

Next, if the filler F on the embossed body W reaches the first sliding portion 4 (the upstream side sliding portion), the slide body 6 is moved by the first drive mechanism 20 and the second drive mechanism 30, and as shown in fig. 5, the filler F abutting against the side surface of the slide body 6 enters between the acting surface 6A of the slide body 6 and the embossed body W, and the filler F caught by the acting surface 6A moves in the moving direction of the slide body 6 and enters the recessed portion W3 of the embossed body W. Even when the packing F does not enter the recess W3 through the slider 6 that first comes into contact with the packing F, the slider 6 that is adjacent to the slider 6 comes into contact with the packing F, and the packing F is guided to the recess W3 again.

According to the present invention, the amount of movement per unit time of an arbitrary point P in the working surface 6A of the slider 6 can be extended by using the first driving device and the second driving device, and particularly, by providing a plurality of sliders 6 in the slider 4 and arranging a plurality of sliders 4 in parallel in the slider, the filler F on the embossed body W is uniformly supplied to the embossed body W by the sliding process using the sliders 6, and the efficiency of entering into the recessed portion W3 of the embossed body is also improved. Therefore, according to the present invention, the ratio (filling ratio) of the number of fillers F filled in the recessed portions W3 to the number of recessed portions W3 of the embossed body W can be preferably 90% or more, more preferably 95% or more, still more preferably 97% or more, and particularly 99.5% or more. The filling rate can be determined by the same method as the remaining rate as described below. As described above, the present invention is not necessarily limited to the filling rate of approximately 100%.

In addition, if the slide body 6 of the slide device 1 of the present invention is used, the accumulation of the filler is less likely to occur around the slide body 6, as opposed to the accumulation of the filler F occurring upstream of the squeegee in the past printing device or the like, and the filler can be prevented from being damaged by the mutual friction between the fillers at the accumulation of the filler.

In the sliding process by the slider 6, as shown in fig. 6, when the filler F has entered the recess W3 at the destination of movement in the case where the filler F is moved on the embossed body W by the slider 6, the filler F is not pushed into the recess W3 but is removed from the surface of the embossed body W. In this case, the sliding device 1 functions as a removal device for residual filling. In the present invention, another device for removing unnecessary filler as a separate step may be added.

In this regard, according to the apparatus of the present invention, the ratio (remaining rate) of the number of fillers remaining on the embossed body W without entering the recessed portion W3 per unit area of the sliding target region of the embossed body W to the number of recessed portions W3 per unit area can be preferably 2% or less, more preferably 1% or less, and still more preferably 0.5% or less.

Preferably, the remaining rate is obtained by: in the sliding region of the embossed body W, a rectangular region having 5 or more, preferably 20 or more sides and a side of 200 μm or more is selected so that the total area thereof is 1 mm²Above, preferably 4 mm²In the above, the number of the recesses W3 of the embossed body W and the number of the fillers remaining on the embossed body W without entering the recess W3 were determined in the area. When the total area of the embossed body W is very large, it is preferable to arbitrarily select 10 or more regions of 1% of the area and measure the remaining rate at the selected portions. The filling rate can also be determined by measuring the number of the recesses W3 and the number of the recesses filled with the filler by the same method. The number of the recessed portions W3 may be measured in advance, and the number density of the recessed portions W3 per unit area may be determined.

The number of recessed portions W3 per unit area, the number of recessed portions W3 filled with filler, and the number of filler remaining on the embossed body without entering the recessed portions W3 can be measured by an optical microscope such as a metal microscope, an electronic microscope such as SEM, or other well-known observation means. It can be easily obtained by using well-known image analysis software (for example, WinROOF (san go business corporation), a like jun (a like く/(registered trademark) (asahi chemical engineering corporation), etc.).

When the difference between the ratio of the number of fillers F per unit area supplied to the sliding target region of the embossed body W to the number of recesses W3 per unit area (supply rate) and the ratio of the number of fillers entering the recesses W3 per unit area to the number of recesses W3 per unit area (filling rate) is defined as the surplus rate (surplus rate = supply rate-filling rate), the surplus rate can be preferably 160% or less, more preferably 105% or less, and still more preferably 50% or less.

The moving speed of the slider 6 by the first driving mechanism 20, the moving speed of the slider 6 by the second driving mechanism 30, and the conveying speed of the embossed body W by the conveying means 3 are appropriately selected in accordance with the size, shape, distribution density of the recessed portions of the embossed body, the maximum diameter, properties, and the like of the filler F.

< post-treatment of sliding treatment >

After the filler is supplied to the recessed portions on the surface of the embossed body, a curable liquid substance may be applied to the surface of the embossed body to which the filler has been supplied, and cured to provide a resin layer on the surface of the embossed body, for the purpose of protecting the arrangement state of the filler. The resin layer may be provided by directly bonding the resin film to the surface of the embossed body to which the filler has been supplied. Further, the resin layer or the resin film provided on the surface of the embossed body to which the filler has been supplied may be peeled off, and the filler may be moved to the resin layer or the resin film or the like which is separate from the embossed body. As the curable liquid material or the resin film, those used for a known adhesive material or adhesive material can be used. The curable liquid material or the resin film may contain a fine filler different from the filler and smaller than the filler.

The material of the transfer destination in the case where the layer provided on the surface of the embossed body after the filler has been supplied or the filler supplied to the surface of the embossed body is transferred to another material can further contain a material other than the resin. The material other than the resin can be appropriately selected from various materials in the same manner as the material of each layer in the case of forming the embossed body into a laminated structure.

After the filler has been supplied to the embossed body, a sliding process of ejecting a solvent may be performed as a sliding object to remove an excess filler existing outside the recessed portions of the embossed body. According to the present invention, such sliding processing can be performed so as to maintain the arrangement state of the filler.

The above-described treatment after the filler has been supplied to the embossed body can be performed regardless of the method of processing the surface irregularities of the embossed body W or the surface material. Therefore, the present invention can be applied to a case where the surface irregularities of the embossed body are formed by laminating either a layer having surface irregularities or a layer having holes. The present invention can be applied to a case where the embossed body is formed of a laminate structure of a plurality of layers, and the embossed body is formed of a laminate structure of a plurality of layers. For example, when the surface of the embossed body W is formed of a metal layer having an empty hole, the above-described treatment can be performed in order to protect the arrangement state of the filler having entered the hole and to move the filler having entered the hole to another material.

The present invention can be provided with various peripheral devices as long as the sliding device of the present invention is provided. For example, when the object W to be slid is a plate-shaped embossed body, it is possible to provide a conveyor-type conveying mechanism or a fixing mechanism that continuously feeds out the objects to be slid to the sliding device, and a collecting device that collects the plate-shaped embossed body after the sliding process to a predetermined place.

The means for providing the resin layer or the resin film, which protects the arrangement state of the filler, and the like, can be provided on the surface of the embossed body to which the filler has been supplied. The present invention also includes a device in which an inspection mechanism (a camera or a sensor) for checking a filling state, a remaining state, or a state of presence of a stretched filler in the slide device is incorporated.

Examples

The present invention will be described in detail with reference to examples.

Example 1

(1) Device constitution

As the slide device 1, a device having two slide portions 4 and arranged in parallel in the conveyance direction (arrow Z) of the film-like embossed body W is manufactured. In this case, the working surface 6A and the surface material 6B of each slider 6 are formed of a bottomed cylindrical molded body (thickness 20 mm) of polytetrafluoroethylene, and a sponge is put therein as the elastic material 6C. The slider 6 has a cylindrical shape, and the diameter of the working surface 6A is 80 mm. Five sliders 6 (closest distance between the sliders 6 is 14 mm, they are arranged radially around the center axis of the slider 4, each slider 6 is rotated around the center axis by the first drive mechanism 20, and the slider 4 is rotated around the center axis of the slider 4 by the second drive mechanism 30) are provided in one slider 4, the distance between the center axis of each slider 6 and the center axis of the slider 4 is 80 mm, the width of the sliding target region is defined as the width of one slider 4, and the distance between the center axes of two sliders 4 arranged in the conveyance direction of the sliding target W is 300 mm.

As the object W to be slid, a roll of an embossed body (length 100M or more) in which cylindrical depressions having an opening diameter of 6 μ M and a depth of 7 μ M are arranged in a hexagonal lattice having an inter-center distance of 10 μ M was used, the cylindrical depressions having an opening diameter of 6 μ M and a depth of 7 μ M being formed in a film having a thickness of 30 μ M by photocuring a photocurable resin composition containing 100 parts by mass of an acrylate resin (アクリレート resin) (M208, tokyo synthesis corporation) and 2 parts by mass of a photopolymerization initiator (IRGACURE 184, BASF) laminated on a PET film (thickness 50 μ M). The width (i.e., the film width) of the sliding object W is set as follows: the width of the sliding target region is sufficiently larger than the width of the sliding target region, and the center of the sliding target region in the film width direction is the center of the film width.

The sliding treated product F was a filler having a particle size of 5 μm and made of a polymethyl methacrylate-based crosslinked product (a filler obtained by classifying Eposter (エポスター) MA1006 manufactured by Japan catalyst Co., Ltd.).

(2) Touch length, filling rate and remaining rate of slider

In the above-described sliding apparatus, in order to find the sliding process condition of the optimum mode for reducing the remaining rate, the following sliding test was performed: the rotational speed of the slider 6 by the first drive mechanism 20 is changed within a range of 20 to 100 rpm, the rotational speed of the slider 4 by the second drive mechanism 30 is changed within a range of 20 to 100 rpm, and the linear speed of the conveying means 3 is set to 1, 2, or 3 m/min.

In each sliding test, the contact length of the slider 6 was calculated by simulation. Here, the "contact length of the slider" refers to the total length of the trajectories of the reference points at the action surface 6A of the slider 6 that pass through a predetermined reference point in the slide object W during the sliding process, and when the action surfaces 6A of the plurality of sliders 6 pass through the reference point, the total length of the trajectories of the reference points at the action surfaces. In the present embodiment, a point on the center line of the width of the embossed body is used as a reference point, and the total length of the locus of the reference point on the working surface 6A passing through the reference point during the sliding process from the time the reference point reaches the upstream-side sliding portion 4 to the time the reference point leaves the downstream-side sliding portion 4 is added.

Fig. 7 shows a relationship between the rotational speed (rpm) of the slider 6 and the contact length of the slider 6.

On the other hand, the filling rate of the filler in each sliding test was measured in the following cases: the filler F is supplied so that the number of the fillers F per unit area in the sliding target region of the embossed body W is 1.4 times or more and 1.5 times or less the number of the recesses W3 per unit area.

Here, the filling ratio is a ratio (%) of the number N1 of fillers entering the depressions of the embossed body to the number N0 of depressions of the embossed body (100 × N1/N0) per unit area of the sliding target region of the embossed body W.

As the filling rate, in the central region (60% of the center in the width direction of the sliding target region) of the sliding target region of the embossed body W obtained by sliding the embossed body W in the conveyance direction by 100 m or more, arbitrary regions of 1 mm × 1 mm at 10 spots were extracted, and the number of particles entering the recessed portion W3 in each region was measured and calculated. Further, the number of particles remaining on the embossed body W without entering the recessed portion W3 in the same region was measured, and the remaining rate was calculated.

Fig. 8A shows a relationship between the contact length of the slider and the filling rate of the filler.

As is clear from fig. 8A, in this test system, if the contact length of the slider is in the range of 1000-.

The survival rate was 2% or less at any measurement site.

In fig. 8A, it was confirmed that: when the filling rate and the residual rate are measured at the starting point of the sliding process of the embossed body, a point 1.5 m downstream from the starting point, a point 10m downstream from the starting point, and a point from the starting point to 100 m every 10m downstream from the starting point (12 points in total) after the filling rate of the filler of 97% or more, for the embossed body, both the filling rate and the residual rate are 97% or more and 2% or less.

The remaining percentage of the filler in each sliding test was measured in the case where the filler F was introduced so that the number of supplied fillers F per unit area in the sliding target region of the embossed body W was 1.4 times or more and 1.5 times or less the number of recesses W3 of the embossed body W per unit area. Here, the remaining percentage is a value calculated from the remaining percentage = supply rate-filling rate when the ratio of the number of fillers F per unit area supplied to the sliding target region of the embossed body W to the number of recesses W3 per unit area is set as the supply rate Ns (%), and the ratio of the number N1 of fillers entering the recesses W3 per unit area to the number N0 of recesses W3 per unit area is set as the filling rate (%) (100 × N1/N0). Fig. 8B shows a relationship between the contact length of the slider and the remaining amount of the filler.

As is clear from fig. 8B, in this test system, the contact length of the slider is 1000 mm or more, and the remaining rate is reduced to 42% or less, so that the supply amount of the filler F can be reduced.

Further, in the above-described sliding test, the relationship between the rotational speed of the slider and the contact length of the slider in the first drive mechanism 20 is shown for each linear velocity in fig. 9. From fig. 8A and 8B, it is understood that in the relationship between the sliding processed object and the sliding object, the contact length of the sliding body is preferably set to be about 1500 mm to 3200 mm (gray full-painted region), and therefore, it is understood that in order to make the filling rate approach 100% and reduce the remaining rate, the linear velocity is preferably set in a predetermined range according to the rotational speed of the sliding body. The preferred ranges of the rotational speed of the slider, the contact length of the slider, and the linear velocity are different depending on the combination of the object to be slid and the object to be slid, or the purpose of the sliding process.

For reference, in the apparatus configuration of example 1, in place of the two sliding portions 4, a scraper (forming material: urethane, length (length in the direction perpendicular to the conveying direction of the sliding object W) of 120 mm, thickness 10 mm) was provided so that the lower edge of the scraper was in contact with the sliding object W (angle set at 70 °), and the filling ratio and the remaining ratio of the filler were measured in the same manner as in example 1 at a linear speed of 2 m/min and a pressing pressure of 0.1 MPa. In this case, the amount of filler supplied is gradually increased, and the filling rate and the remaining rate are measured for each amount of supply, and the amount of supply with the filling rate of 97% or more is determined. The supply amount was about 4 times the supply amount of the same linear velocity (2 m/min) pattern as in example 1, and the remaining rate was about 12 times.
