In addition, said backer roll 20 is made up of for example transparent glass tube, still, if having the intensity and necessary ultraviolet permeability of anti-pressurization, then is not confined to its material especially.
Then, the effect of the applying device 1 of said formation is described, specify the coating method of the utility model.
At first, paper wood 2 from paper wood unwinding device 4 to paper wood devices for taking-up 6 on one side by deflector roll 5 channeling conducts, on one side carry out conveyance by the paper wood carrying device.And, make near the applicator roll 16 reverse driven in rotation the upstream side that is arranged at solidification equipment, via roller 17 resin solutions in the storagetank 15 are attached on its outer peripheral face, and this resin solution are applied on the surface of paper wood 2 of institute's conveyance.
When this resin solution of coating,, on the surface of paper wood 2, form to approach and (convert through weight and be approximately 3g/m by the coating weight of roller 17 decision applicator rolls 16
2～153g/m
2) and the coated film of homogeneous thickness.
For the paper wood 2 of the coated film that as above-mentioned, is formed with resin solution, its surface that is not formed with coated film one side and backer roll 21 are joined, and with paper wood 2 reel the said a pair of backer roll 20 that is driven in rotation, between 21.
On the other hand, with film 10 from film unwinding device 12 to film devices for taking-up 14 on one side by deflector roll 13 channeling conducts, on one side carry out conveyance by the film carrying device.In this conveyance path, film 10 is involved in to a pair of backer roll 20, between 21 with said paper wood 2, wherein clip coated film and be superimposed together with paper wood 2.And, pass backer roll 20 and film 10 from the ultraviolet ray of first ultraviolet radiator 22, shine to be in and be crimped on paper wood 2 surface and go up on the coated film under the states.Like this, paper wood 2 and film 10 crampings between backer roll 20,21, and are crimped onto coated film on the film 10, coated film is solidified with a certain degree.
In addition, utilize backer roll 20,21 and film 10 crimping before, the coated film surface is shone from the ultraviolet ray of first ultraviolet radiator 22 from making the coated film of coating on the paper wood 2.Therefore, after the coated film surface began to solidify, the crimping that utilizes backer roll 20,21 to carry out film 10 formed coated film through this crimping smoothly.And, with begin to solidify from the coated film surface before the situation that begins to be crimped on the film 10 compare, the engaging force between coated film of having solidified and the film 10 a little less than, therefore, can be easily after state and carry out peeling off of film 10 in the film stripping process.
In addition, also consider the method opposite with the utility model, said method is; Be coated with the outside line cured resin coating to form coated film at the film side purple; Make film and the mutual crimping of paper wood through this backer roll, and irradiation ultraviolet radiation solidifies coated film, solidify after-applied external force; Film is peeled away from paper wood, and coated film is transferred on the surface of paper wood.But in this case, the coated film of film surface is from will before paper wood 2 crimping, beginning by pressurized roller, and by the first ultraviolet radiator irradiation ultraviolet radiation, therefore, under the state that is attached with coated film on the film surface, coated film begins to solidify.Therefore, coated film is stronger to the engaging force of film surface, but to the engaging force of the paper wood of its reverse side coated film a little less than, in the film stripping process, film is needed brute force from solidifying when coated film is peeled off.Film is peeled off required power to be become the power (film is with respect to tension force) that film is extended and works, and therefore, this also becomes the reason that film extends, even has damaged the flatness on the surface of film.Therefore, when being crimped onto film 10 again after coated film begins to solidify as above-mentioned, the state that the engaging force of film 10 is died down in coated film is the function of performance smoothing down, like this can not can film 10 be acted on strong traction force ground and peels off.Therefore, can improve the durability of using film 10.
In addition, be formed with the occasion of the film of little jog from the teeth outwards, also can expect same effect.Be used as the occasion of the film 10 of negative when particularly on coated film, forming hologram, when taking place to extend under the traction force when said peeling off, delicate change takes place in the position of ultra tiny jog, thereby is difficult to form according to the such hologram of design; If in the time of can reducing to act on the traction force on the film, then can suppress its extension.Therefore, if can reduce the required power of peeling off, then go far towards to improve durability in the occasion that forms hologram film 10 like above-mentioned appearance.
The film 10 and the paper wood 2 that utilize the coated film of above-mentioned semi-solid preparation and be superimposed with each other; From backer roll 20,21 to second ultraviolet radiator 23 carried out conveyance thereafter; Make ultraviolet ray expose to coated film again at this, coated film is solidified fully through film 10 from second ultraviolet radiator 23.In addition, the coated film that is formed on the paper wood 2 is thinner, and is exposed in the extraneous air in conveyance midway, thereby the oxygen isolation does not take place in chemical reaction, therefore, can accomplish the curing of coated film rapidly, doing over again of cured can not taken place.
When coated film is solidified fully, with paper wood 2 and film 10 to the stripping off device conveyance, by separate roller 24 with film 10 to from apart from paper wood 2 away from the direction guiding and draw stripping and paper wood 2 by a pair of maintenance roller 25,25 clampings with resisting mutually with the film that is drawn stripping 10.That kind makes resin be impregnated in the paper wood 2 with a certain degree as stated; Therefore; The coated film of having solidified can strong surface with paper wood 2 engages and remains on this surface and coated film begins to solidify back and film 10 crimping mutually, thereby film 10 separates from coated film easily.In addition, under the situation of film 10 surface smoothings, the surface that is formed at the curing coated film on the paper wood 2 so also can smoothed.On the other hand, the film that is formed with jog from the teeth outwards is during as negative, will be transferred on the coated film with the jog of the jog counter-rotating of this film.
The paper wood 2 that the coated film that the surface has been solidified as said applies is wound into by paper wood devices for taking-up 6 and rolls volume, and on the other hand, film 10 coils into roller by film devices for taking-up 14.The curing coated film (resin molding) that will form through said series of processes with thin and uniformly on the thick surface that is coated in paper wood 2 of film, and is impregnated in the paper wood 2 with a certain degree, thereby has sufficient engaging force.
In addition; Film 10 only engages with coated film during crimping curing process to the stripping process that has utilized backer roll 20,21 etc.; Therefore; Can shorten time of engaging with resin solution (coated film) and engage, thus, be coated with film 10 surfaces that can suppress to engage deteriorations (because of crimping and peel off the reduction that causes flatness) take place with the cloth film with the coated film of semihard state.Therefore, repeated use film 10 under the state that is coated with the function that makes the smoothing of cloth film can kept.
In addition; Applying device 1 in above-mentioned first embodiment; Even be used to make the film 10 of the coated film smoothed that is formed on the paper wood 2, also can keep the smoothing function and the jog transfer printing function of film 10, therefore also be suitable for using the occasion of the film 10 of formula for no reason.
See also shown in Figure 2ly again, it is the figure of applying device 1 of second embodiment of expression the utility model.
This second embodiment is, with the surface of the thin film cladding scraps of paper 30 of ultraviolet curable resin.In addition, to said first embodiment with the same Reference numeral of a part of mark, and omitted the explanation of its repetition.
In this second embodiment, be provided with: feed arrangement 31, it is supplied with the scraps of paper 30 many ground as the paper wood carrying device to cut out to being scheduled to the big or small scraps of paper 30 as applying object; And storage facility 32, hold the scraps of paper that applied 30 are overlapping successively.At this; The scraps of paper 30 are and the rectangular scraps of paper of the said first embodiment different successive; Feed arrangement 31 with each scraps of paper 30 no gap continuously successively to resin imparting device, 20,21 supplies of backer roll; Can make the coated film smoothed that is formed on the scraps of paper 30, and make a concerted effort its coating with strong cohesiveness.
In addition, in this second embodiment, film 10 is formula type for no reason, should be provided with film driven roller 33 for conveyance drives film 10 for no reason.That is, when this roller 33 during by driving mechanism (not shown) driven in rotation, film 10 is successively to the conveyance that circulates of solidification equipment, stripping off device and solidification equipment for no reason.
According to this second embodiment; Also film 10 is folded on the coated film of the ultraviolet curable resin coating that is formed on the scraps of paper 30 by backer roll 20,21; Make the surface crimping each other of coated film and film 10; Meanwhile, irradiate ultraviolet ray so that the coated film semi-solid preparation from first ultraviolet radiator 22, and then after making this this curing of coated film with the ultraviolet ray irradiation from second ultraviolet radiator 23; By separate roller 24 film 10 is peeled off from the scraps of paper 30, can be formed and the same resin molding of said first embodiment in the surface applied of the scraps of paper 30.
In addition; In said first, second embodiment, the resin imparting device with applicator roll 16 has been shown; As long as but this resin imparting device can be applied to ultraviolet curable resin on the surface of paper wood 2; For example, also can take with modes such as the mode of sprayer ejection and coating ultraviolet curable resin coating and gravure, aniline printing, offset printing, bar coating machines.
In addition; In said first, second embodiment; Show the example of second ultraviolet radiator 23 that makes this curing of coated film; But also can omit second ultraviolet radiator 23, only make this curing of coated film with first ultraviolet radiator 22 according to the material of ultraviolet curable resin or the exposure of first ultraviolet radiator 22.
In addition, in said each embodiment, enumerate the example of coating as the representative ultraviolet curable resin of particular light ray cured resin has been described, but the particular light ray cured resin in the utility model is not limited thereto.For example, also can adopt through electronics line (ionizing radiation: the electronics line cured resin that irradiation electron beam) is solidified.And the film under this situation has the characteristic that this electronics line is seen through, and irradiation light also can shine the electronics line.
Ultraviolet ray has been suitable for using ultraviolet ray to see through the occasion of the base material of film and transfer printing as the such paper of aluminium system.In addition, the electronics line is used for the occasion that film can't make ultraviolet ray pass.
Adopted the paper applying device of this utility model, the intensity etc. that can meet the demands, the thickness of resin molding is thinner, also can apply the paper wood surface.And the resin molding that forms (curing coated film) when waste paper regenerated, can use suitable solution from paper wood, resin molding to be removed easily even thickness is thin also not to be hindered, thereby the paper wood of the good matter of can regenerating.In addition, paper wood has been carried out surface applied, therefore, when this paper wood being processed into sack etc., resin molding can have been sealed through heating and pressurizing as bonding agent with resin molding.And then resin is impregnated in the paper wood with a certain degree, and therefore, paper wood and resin molding can not peel off each other yet after the heating and pressurizing.In addition, only film is used for the smoothing of coated film or the transfer printing of jog, and does not need heating, therefore, can suppress the deterioration of film surface, and can improve the durability of film.And then; Just wanted the superimposed curing that particular light ray begins coated film of shining before at the film of paper wood and particular light ray permeability; After coated film begins to solidify, make coated film and film surface crimping and see through this film irradiation particular light ray this coated film is solidified, then can weaken the tension force that when stripping film, acts on the film, therefore; Even the repeated use film also can suppress its extension.Therefore, can improve the durability of film, this point is particularly more obvious in the film of ultra tiny jogs such as transfer printing hologram; Moreover, because it can apply thin resin molding with abundant engaging force on paper, thereby can satisfy desired intensity; And when waste paper regenerated, make resin molding become film as far as possible, and utilize easily and stir or aqueous slkali removal film, and can make heating or pressurization reach Min.; Thereby the pressure that suppresses the film jog is collapsed, is out of shape or extends, and further improves the durability of film, and is simple and practical; Stable and reliable working performance, the scope of application are comparatively extensive.
In this specification, the utility model is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and the scope of the utility model.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
