Detailed description of the invention
In Fig. 1 (a), (b), indicate the configuration example of the scraper plate supporter of the present invention.
Scraper plate supporter 1 is that metallic plate is implemented stamping process, and the bending line along the regulation extended in the longitudinal direction carries out bending and formed, and has elastomer bonded face 2 and intensity reinforcement face 3. By by sheet metal bent and arrange intensity reinforcement face 3, the rigidity of scraper plate supporter 1 increases and becomes to be not easy deformation. On elastomer bonded face 2, have the elastomeric joint 4 being bonded to elastomer 8. Elastomeric joint 4 can be at the arbitrary face of the exterior and the interior in elastomer bonded face 2.
As the material of scraper plate supporter 1, if the outstanding material of rigidity then can not be done special restriction and use. Such as, the metallic plate of plated steel sheet, hot-dip galvanized steel sheet, aluminum, rustless steel etc. can be enumerated. Among them, owing to plated steel sheet, hot-dip galvanized steel sheet processability are outstanding, it is easy to reach dimensional accuracy, therefore particularly preferably. Can implement chromate process and zinc phosphate process etc., it is also possible to inorganic lubricant epithelium and organic lubricating film are set on a metal plate.
On the scraper plate supporter 1 of this configuration example, perforate has 2 holes and reference for installation structure 5 and 2 installing holes 6. When scraper plate is installed to the electro-photography apparatus of OA equipment etc., reference for installation structure 5 is used to make that scraper plate is chimeric with pin being pre-formed on electro-photography apparatus etc. carries out para-position. The shape of reference for installation structure 5 is not limited to hole, it is possible to be the shape that can position when to the installation of electro-photography apparatus. Such as, projection can be enumerated, recessed etc. Installing hole 6 is used to, when reference for installation structure 5 is chimeric with the pin being formed on electro-photography apparatus, be fixed on electro-photography apparatus with screw etc. Design according to electro-photography apparatus, reference for installation structure 5 and installing hole 6 are arranged on the position of regulation in elastomer bonded face 2 or intensity reinforcement face 3.
Owing to the interval between reference for installation structure 5 is more wide, then more improve with positional precision when selling chimeric of electro-photography apparatus, be therefore generally arranged around each 1 at both ends and amounted to 2 reference for installation structures 5. The quantity of reference for installation structure 5 can be more than 2. In preferred reference for installation structure 51 is circular hole, and remaining is the elongated hole with the major diameter parallel with the length direction of scraper plate supporter. By making reference for installation structure 5 for elongated hole, it is possible to absorb the inequality in dimensional tolerance, thus carrying out para-position exactly. Position and quantity that installing hole 6 carries out perforate are not particularly limited. Installing hole mostly 6 be near both ends perforate each 1 amount to 2 or on both ends and central part perforate each 1 amount to 3. Although the shape of installing hole 6 is not particularly limited, but is generally circular hole.
Beyond reference for installation structure 5, the scraper plate supporter 1 of the present invention has the machining benchmark structure 7 of more than 2.
As described later, when placing scraper plate supporter 1 on fixture 10 and elastomer 8 are carried out joint to make scraper plate 9, machining benchmark structure 7 is used to chimeric with the embedded structure 11 of fixture 10 carry out para-position. Even for variform scraper plate supporter, it is possible to make fixture 10 generalization, thus machining benchmark structure 7 is arranged on elastomer bonded face 2. This is owing to the shapes such as the bending angle in intensity reinforcement face 3 of each electro-photography apparatus, width are different, therefore when arranging machining benchmark structure 7 on intensity reinforcement face 3, then cannot make fixture generalization. If being in elastomer bonded face 2, the position then arranging machining benchmark structure 7 is not particularly limited, can be the outside in elastomeric joint 4 as Suo Shi Fig. 1 (a), it is also possible to be the inner side in elastomeric joint 4 as Suo Shi Fig. 1 (b). Owing to the interval of machining benchmark structure 7 is more wide, positional precision when carrying out placing on fixture 10 more improves, it is thus preferred to be arranged near the both ends of scraper plate supporter 1. Although in Fig. 1 (a), (b), machining benchmark structure 7 is formed on the inner side being more in length direction than reference for installation structure 5 but it also may formed in the outside more leaning on length direction than reference for installation structure 5. Additionally, due to apply stress with elastomer 8 equably when engaging, it is not easy to produce skew, it is thus preferred to machining benchmark structure 7 is formed on position equidistant from the length direction central part of elastomeric joint 4.
Can three-dimensionally form machining benchmark structure 7, the three-dimensional shape of hole, recess, protuberance etc. can be enumerated. Machining benchmark structure 7 one part can also be overlapping with the limit of scraper plate supporter 1. For example, it may be the otch that the machining benchmark structure 7 i.e. part in hole is overlapping with the limit of scraper plate supporter 1. Additionally, its geometry is not particularly limited, cylindric, coniform, circular cone shape, spherical, triangle taper, triangle column, pyrometric cone mesa-shaped, corner taper, corner column, quadrangular pyramid mesa-shaped, raised line, recessed bar etc. can be enumerated. That is, the machining benchmark structure 7 of the present invention determines with the combination of three-dimensional shape and geometry, can enumerate the protuberance etc. of columned hole, spherical recess, quadrangular pyramid mesa-shaped. Although scraper plate supporter 1 has the machining benchmark structure 7 of more than 2, but can be different shapes respectively. If the three-dimensional shape of machining benchmark structure 7 is hole or recess, then can maintain former state and carry out utilizing without implementing processing in electro-photography apparatus side. If the three-dimensional shape of machining benchmark structure 7 is protuberance, although the hole corresponding with this protuberance or recess must be arranged on electro-photography apparatus side, but can coordinate with reference for installation structure 5 and improve positional precision when installing.
When the three-dimensional shape of machining benchmark structure 7 is hole or recess, it is preferable that relative to wherein 1 machining benchmark structure, remaining machining benchmark structure is formed as the shape extended on the length direction of scraper plate supporter 1. Such as, can enumerate and wherein 1 machining benchmark structure is formed as circular hole or recess, and remaining machining benchmark structure is formed as oblong hole or recess. So, it is possible the inequality absorbing in dimensional tolerance identically with described reference for installation structure 5. At this, the oval shape referred to 2 parallel straight lines 2 semicircles of connection, is different from being ellipse from the set of the distances of 2 fixed points and equal points in the plane.
The scraper plate supporter 1 that machining benchmark structure 7 is hole has following situation when as scraper plate 9, i.e. toner is spilt to outside by hole, causes polluting inside electro-photography apparatus. Therefore, when may result in toner and spilling, it is considered to have the unit of blind hole. The unit of blind hole is not done special restriction. As shown in Fig. 2 (a), if in the outer machining benchmark structure 7 arranged of elastomeric joint 4, then can use band blind hole. As band, it is possible to use be coated with the band of binding agent, bonding agent on thin film, adhesive tape, paper etc., and do not do special restriction. Additionally, beyond band, it is possible to use screw, rivet, encapsulant etc. Additionally, as shown in Fig. 2 (b), if in the machining benchmark structure 7 formed in elastomeric joint 4, then elastomer 8 can also be engaged in the way of coverage hole and closes. Even if if it addition, scraper plate 9 is installed in the position not spilling toner or toner passes through on the position that hole does not also come into question, then to close machining benchmark structure 7 i.e. hole.
Elastomer 8 is engaged with the elastomeric joint 4 of scraper plate supporter 1 and forms scraper plate 9. Scraper plate supporter 1 is engaged when by placing on fixture 10. In figure 3, an example of fixture 10 is indicated. On fixture 10, it is formed with the embedded structure 11 chimeric with the machining benchmark structure 7 of scraper plate supporter and namely sells. As shown in Figure 4, being fitted together to by the embedded structure 11 of the machining benchmark structure 7 of the scraper plate supporter 1 of placing on fixture and fixture, scraper plate supporter is by para-position exactly. When chimeric with described machining benchmark structure 7, as long as embedded structure 11 can fix the shape of scraper plate supporter, and it is not limited to pin. Such as, if the three-dimensional shape of machining benchmark structure 7 is hole or recess, then embedded structure 11 can be the protuberance of pin, raised line etc. Additionally, if the three-dimensional shape of machining benchmark structure 7 is protuberance, then embedded structure 11 can be the recess of hole, recessed bar etc. If machining benchmark structure 7 is the hole formed in the inner side of elastomeric joint 4, then need below the thickness that height is scraper plate supporter 1 of embedded structure 11, so that when the joint of elastomer 8, the top of embedded structure 11 not with elastomer contact and cause hinder engage.
As it has been described above, machining benchmark structure 7 is arranged near the both ends of scraper plate supporter 1. The width of roller that the length of scraper plate supporter 1 comes in contact with scraper plate, rotary drum, band etc. is determined. The width being additionally, since these rollers, rotary drum or band etc. is that the size according to printing is determined, therefore the corresponding A3 of the width of scraper plate supporter 1 with, A4 with etc., the size of paper and exist. Thus, fixture 10 is also only prepared with the size as A3 use, the such paper of A4. To this, also reference for installation hole was used as position reference during elastomer bonded in the past, so that be the different fixture in the position of the different scraper plate supporter manufacture embedded structure in the position in each reference for installation hole.
Although considering from aligning accuracy this point, preferably the size of corresponding paper prepares fixture 10, even if being the scraper plate supporter of A3, by arranging machining benchmark structure 7 on the position identical with the scraper plate supporter of A4, it is also possible to make fixture 10 generalization that the manufacture of A3 scraper plate supporter and A4 scraper plate supporter uses. Along with the numeral of the size of paper reduces 1, its area becomes 2 times. Being 297mm �� 420mm owing to A4 paper using is 210mm �� 297mm, A3 paper using, therefore along with numeral reduces 1, its length of side is the square root of 2, and becomes about 1.414 times. By being arranged around machining benchmark structure 7 and to arrange machining benchmark structure 7 with A4 scraper plate supporter same intervals on A3 scraper plate supporter at two ends of A4 scraper plate supporter, it is possible to make fixture 10 generalization that the manufacture of A4 scraper plate supporter and A3 scraper plate supporter uses.
When the both sides of scraper plate supporter 1 with plate S1 described later are engaged, use and have the fixture 10 that 2 scraper plate supporters 1 can be carried out placing in the way of elastomeric joint 4 is opposed. On this fixture 10, width central part is provided with blade and accepts interval 12. Fig. 5 illustrates the ability to 2 scraper plate supporters of placing and has the fixture 10 in blade undertaking space 12 on width central part. The space that when blade accepts space 12 for being used for being cut off in the direction of the width by plate on fixture 10, cutting knife passes through. By fixture 10, there is blade and accept space 12, it is possible to effectively plate is cut off on fixture 10, and manufacture section point-blank. The section of elastomer 8 cut off on fixture 10 manufactures point-blank, it is thus possible to engages with scraper plate supporter 1 with original state and forms scraper plate 9, without cutting out again. Owing to need not be used for determining width dimensions, determine cutting out of crest line, therefore Quality advance, yield rate raising, garbage reduce. Cutting out operation additionally, due to can omit, therefore manufacturing cost is lowered.
Elastomer 8 engages with the elastomeric joint 4 of scraper plate supporter 1 and forms scraper plate 9. The Thermocurable polyurethane of 2 liquid types of material preferred the Thermocurable polyurethane, particularly non-solvent of elastomer 8. Elastomer 8 can be the overall elastomer formed by uniform resin combination, it is also possible to be the multilayer elastomeric using different resin combinations on marginal layer 13 and basic unit 14 and being formed. Multilayer elastomeric can use whole the multilayer elastomeric being provided with marginal layer 13 by entire surface and only be provided with any one of Local Multilevel elastomer of marginal layer 13 on the local contacted with rotary drum etc. Fig. 6 (a) is shown with the profile of the scraper plate of whole multilayer elastomeric, and Fig. 6 (b) is shown with the profile of the scraper plate of Local Multilevel elastomer. Additionally, on elastomer 8, it is also possible to form the matsurface corresponding with trickle toner.
The manufacturing process of elastomer 8 is not particularly limited, it is possible to use flospinning, progressive forming method any one. In progressive forming method, after resin combination is cast the grooving of forming drum, time to being removed as band is that forming drum carries out about half about 30��60 seconds rotated. When the elastomer 8 that progressive forming is made up of Thermocurable polyurethane, selected isocyanates and polyhydric alcohol, cross-linking agent, catalyst are to design the composition of Thermocurable polyurethane, in order at about 30��60 seconds polymerizing curables to the degree can peeled off from forming drum.
Composition as Thermocurable polyurethane, it is possible to use following composition.
As high molecular weight polyols, can enumerate the polyether polyol of alkylene oxide adduct class of the polyether polyols classes such as Polyethylene Glycol, polypropylene glycol, polyoxytetramethylene glycol or bisphenol-A, the oxirane of glycerol, expoxy propane etc. and the binary acid of adipic acid, phthalic anhydride, isophthalic acid, maleic acid, fumaric acid etc. and ethylene glycol, propylene glycol, 1, polyester polyol that the glycols of 4 butanediols, 1,6 hexanediol, trimethylolpropane etc. is obtained by polyreaction and polycaprolactone glycol, PCDL etc.

Low molecular weight diol is preferably used. And also can add trimethylolpropane, triethanolamine, glycerol and their oxirane, propylene oxide adduct as required as multifunctional composition.
In the manufacture of above-mentioned polyurethane, the equivalent proportion of OH base/NCO base can be 0.8��1.05 from the physical property of the polyurethane generated, it is preferred to the scope of 0.90��1.05. Further according to needing to use the reaction promoters such as general amines, organic tin compound. Include, for example the imidazoles inductor etc. of institute's publicity in No. 2942183 publications of Japanese Patent No., the 0022nd��0023 paragraph. As its concrete example, 2-methylimidazole, 1,2-methylimidazole etc. that in chemical constitution, reaction temperature interdependence is high can be enumerated.
Relative to carbamate prepolymer 100 weight portion, reaction promoter is 0.001��0.5 weight portion, it is preferable that use in the scope of 0.01��0.3 weight portion. As reaction promoter, the reaction promoter owing to having Thermo-sensitive or slow prevents the polyurethane resin constituent being mixed with reaction promoter from producing before forming to solidify, and pot life extends, striking time shortens, it is thus preferred to. Specifically, can enumerate and be referred to as 1,8-diazabicyclo (5,4, the 0) endecatylene-7-acylate of block amine, 1,5-diazabicyclo (4,3,0) nonene-5-acylate or their mixture etc.

In addition, it is contemplated that its quantitative accuracy, dosing pump is preferably used the plunger piston type of more than 3, but is used as geared pump type. Especially, due in progressive forming method, it is preferably used and carries out, with about 30��60 seconds strippable degree, the fast setting formula and the resin combination that solidify, therefore to prevent being detained and suppressing the temperature that causes because of reaction heat to rise in mixing chamber, the type of such low capacity of stirring mixing chamber preferred Japanese Patent Publication 6-11389 publication institute publicity.
Although the polyurethane resin of the Thermocurable of 2 liquid types of the fast setting formula used for progressive forming method has carried out detailed illustration, but the resin as the elastomer that can use in the present invention is not limited thereto, it is also possible to use thermoplastic resin, heat-curing resin any one. In addition it is also possible to use ultraviolet curing resin. Further, resin combination can also comprise solvent. When making resin combination comprise solvent, then can also use the too high resin combination of viscosity or under production conditions for the resin combination of solid, thus the degree of freedom designed increases. But, due to when comprising solvent, then solvent seizes heat of gasification when being evaporated and causes that temperature reduces, therefore in using the progressive forming method having heat-curing resin, described progressive forming method makes resin solidify in the grooving of heated forming drum, in order to keep into high temperature by inside grooving, it is preferred to do not wrap solvent-laden non-solvent.
In progressive forming method, the width of the band of the wide cut banding of progressive forming is formed as the substantially integral multiple of the width of elastomer. Such as, the band of 2 times of width forms 2 deciles after carrying out in the longitudinal direction cutting off and forming plate in width central authorities, such that it is able to form elastomer 8 like this. The band provided by progressive forming method is not limited on width midway to cut off, for instance can also be divided into 10mm width and 20mm width from the band of 30mm width. Additionally, be not limited to be divided into 2, it is also possible to be divided into more than 3.
