Description

The packaging structure of lithographic plate and packing method
Technical field
The present invention relates to a kind of lithographic plate packaging structure, and a kind of lithographic plate packing method that is used to form the lithographic plate packaging structure.
Background technology
Extensively be used in such as lithographic plates such as photosensitive printed board, temperature-sensitive galley and PS (pre-coating photosensitive layer) galleys comprised the electrofax graphic arts process in interior various method for platemaking recent years, so that realize the automation of plate-making process.Lithographic plate is normally made like this, promptly on a substrate, implement surface treatment, independent one or their combination during for example surperficial roughening, anodization, silicate processing or other chemical changes are handled, substrate is the aluminium sheet of sheet material shape or web shaped normally, next apply a photo sensitive coating or heat-sensitive layer also with this layer drying on substrate, the substrate cut that will apply above-mentioned layer afterwards becomes preliminary dimension.Following photo sensitive coating and heat-sensitive layer are referred to as " filming ", and are formed with the surface of filming on the substrate and are called " imaging surface ", do not have to form the surface of filming and are called " non-imaging surface ".
This lithographic plate will stand various plate-making to be handled, and comprises exposure, development, gluing and similar processing.Subsequently, lithographic plate is loaded in the printer, and printing ink is applied on the lithographic plate.Consequently, character, image and analogue can be printed on the paper.
Any lithographic plate all is formed as the mono-thin plate.Therefore, occur breaking, after crackle or the distortion, cause fault easily that promptly experiencing exposure or the back that is heated when developing, image may thicken unclear in bight, side or the inboard of galley, perhaps printing ink can apply brokenly when printing.
Therefore, in order to protect lithographic plate, the protection cardboard can be parallel to lithographic plate under many circumstances and arrange.Specifically, be superimposed as by a plurality of lithographic plates under the situation of a lamination, can placing the protection cardboard every the lithographic plate of predetermined quantity, to protect lithographic plate reliably.The packaged material of lithographic plate that has many protection cardboards as previously mentioned is inner packaging material packing for example, and then carry or storage process in stand operation.After so having settled these protection cardboards, when for example standing to operate, lithographic plate is not easy distortion or crooked.Consequently, can prevent that lithographic plate is impaired.In addition, even there is external force to affact on the lithographic plate, the part of external force also can absorb by protected cardboard, thereby prevents lithographic plate distortion or warpage.
Under many circumstances, when using lithographic plate, packing need be opened, afterwards, each protection cardboard be removed, only in this way the lithographic plate lamination could be taken out from packing.
Yet the action need of removing the protection cardboard expends time in and labour power.In addition, the protection cardboard may be fixed on the lamination by adhesive tape or analogue.In this case, the operation of removing the protection cardboard will expend more time and labour power.
In addition, the protection cardboard is just useless after removal, protects lithographic plate because no longer need with them.Handle discarded protection cardboard and may need to consume a large amount of expenses.For example, when can be used as the waste paper recovery when protecting cardboard only to be made of paper, they can be recovered.But reclaimed waste paper needs special technology and expense usually.In addition, when the protection cardboard is got when for example partly comprising resin material by moulding, then they can not be used as waste paper and reclaim.In this case, the processing of protection cardboard need consume more expense.Under above-mentioned any situation, the user of lithographic plate all needs the interim discarded protection cardboard that stores.Therefore, also need certain expense for storing discarded protection cardboard, and need guarantee to have the storage area.
In addition, making the protection cardboard needs certain expense equally, and this expense can embody in the expense of lithographic plate packaging structure or lithographic plate self.
Next, lithographic plate will stand various plate-making to be handled, and comprises exposure, development, gluing and similar processing.Subsequently, lithographic plate is loaded in the printer, and printing ink is applied on the lithographic plate.Consequently, character, image and analogue can be printed on the paper.
When these lithographic plates are operated, to carry or store in order to implement with low cost, and reduce number of operations, a large amount of lithographic plates is superposeed along thickness direction, forming a lithographic plate lamination, and a carrier member can be placed and be packaged in to lamination for example on the pallet.
An example (seeing Japanese Patent Application Publication document (JP-A) No.3-73946) of this packaging structure has been shown among Figure 14.
In the document, in the disclosed packaging structure 310, arranging an end plate 314 respectively on two end faces of the lamination of lithographic plate 312.End plate 314 is by bolt 316 and together secured to one another.
Yet the operation that utilizes bolt 316 fastening end plates 314 is normally comparatively complicated.In addition, be not used in the device of the fastening operation of automatic enforcement, therefore packing needs to consume a large amount of time and labour power.In addition, when taking apart, bolt 316 need be taken off one by one, thereby the efficient of taking operation apart also can reduce.
In addition, understand local action on end plate 314 from the fastening force of bolt 316.Therefore, need guarantee that end plate 314 is enough thick, in case not-go-end plate 314 depressions or distortion can cause the weight of end plate to increase like this.
A kind of packaging structure 410 has also been proposed, as shown in figure 15 among the above-mentioned JP-A No.3-73946.
In packaging structure 410, be that lamination 418 that the lithographic plate 416 by predetermined quantity constitutes rests on respect to base plate 412 with on upright or the end plate 414 that the bevelled mode forms equally.Afterwards, another end plate 420 is applied on the front side of lamination 418, utilizes bolt 422 with end plate 414 and end plate 420 secured to one another being in the same place subsequently, so that lamination 418 is fixing.
End plate is so and fastening by bolt 422, therefore the same with the packaging structure 310 shown in Figure 14, and the efficient of packing and taking apart operation can reduce.In addition, if guarantee that in order to prevent end plate depression or distortion end plate has certain thickness, then can cause weight to increase.
Summary of the invention

Specifically, various lithographic plate and the various thermosensitive printing versions that laser explosure formula high photosensitivity is filmed that have have been brought into use recent years.Such galley can be that for example above-mentioned lithographic plate (1) is to (3) or analogue.When using these high sensitivity lithographic plates, preferably they are packaged in according in the lithographic plate packaging structure of the present invention.
Here the Wavelength of Laser of mentioning has no particular limits.For example, following laser can use.
(a) range of wavelength is that 350 to 450nm laser, particularly wavelength are the diode laser of 405 ± 5nm.
(b) range of wavelength is that 480 to 540nm laser, particularly wavelength are that the argon laser of 488nm, (FD) YAG ((double frequency) yttrium aluminum garnet) laser, the wavelength that wavelength is 532nm are the solid statelaser of 532nm and the optical filtering Ne-Ne laser that wavelength is 532nm.

(d) range of wavelength is that 800 to 830nm laser, particularly wavelength are infrared ray (quartz conductor) laser of 830nm.
(e) range of wavelength is that 1064 to 1080nm laser, particularly wavelength are the YAG laser of 1064nm.
In these lasers, above-mentioned (b) and the laser that (c) sends all can be applied to the lithographic plate that has photo sensitive coating or heat-sensitive layer of description in front (3) or (4).In addition, above-mentioned (d) and the laser that (e) sends all can be applied to lithographic plate that has photo sensitive coating or heat-sensitive layer of describing in front (1) or (2).Certainly, the relation between Wavelength of Laser scope and sensitization or the heat-sensitive layer is not limited to noted earlier.
In addition, lithographic plate 10 in the present embodiment, the lithographic plate in all above-mentioned (1) to (11) just, all be with following state be loaded into have automatic for the version function platemaking machine or so-called type-setting machine in, promptly at first be made into lamination 12, be supplied in the plate-making process again.Therefore, lithographic plate of the present invention can prevent the imaging surface distortion effectively, and is not fixed against edition mode that supplies of lithographic plate, and promptly they are utilized the automatic edition mechanism that supplies to supply with by the user on earth, still be to be supplied with by hand by the user, or otherwise supply with.Certainly, except above-mentioned (1) to the lithographic plate described in (11), can be loaded into have automatic in version platemaking machine of function or the so-called type-setting machine and other lithographic plates that are fed in the plate-making process also all be included in the lithographic plate 10 of present embodiment.
The shape of lithographic plate 10 has no particular limits.For example, thickness is 0.1 to 0.5mm, long side size (length) is 300 to 2050mm, short side size (width) be 200 to 1500mm and the aluminum sheet that on a surface of printed panel, applied sensitization or heat-sensitive layer can use.
Can also see that from Figure 1A the lamination 12 of lithographic plate 10 forms by this way, promptly be used to protect the inset 14 and the lithographic plate 10 of filming alternately to superpose along thickness direction.The quantity that constitutes the lithographic plate 10 of single lamination 12 has no particular limits.Yet from carrying and the efficient of storage aspect is considered, quantity can be for example 10 to 200.When lamination 12 was made of 10 or above lithographic plate 10, plate can be by the operation of more efficient ground.And when lamination 12 was made of 200 or following lithographic plate, the weight of lamination 12 was limited.Like this, the live load during operation can reduce.In addition, lamination 12 also can be made of the lithographic plate 10 of bigger quantity, so that the conveying of galley and storage are more efficient.That is to say, can be with number of times implementation and operation still less.For example, the maximum quantity of lithographic plate 10 can be set to about 3000.In addition, also can not use inset 14, this depends on the type of lithographic plate 10, so that lamination 12 can only be made of lithographic plate 10.
Filming to be formed on the both sides of substrate, and this depends on the type of lithographic plate.The galley of Tu Fuing is called " two coating galley " by this way.When lamination 12 is made of two coating lithographic plates, also to place an inset 14 below the orlop lithographic plate in Figure 1A.Therefore, the quantity of inset 14 is than more than 10 one of lithographic plates.Consequently, do not have the possibility of the direct contact inner packing paper 16 of filming of lithographic plate 10.Like this, can prevent because of filming impaired with filming of causing of inner packing paper 16 direct contacts.
In addition, only be applied under lip-deep situation of substrate filming, lithographic plate 10 can superpose like this, i.e. their film equal points upwards or equal directed downwards.
The concrete structure of inset 14 has no particular limits, and is imaging surface as long as it can protect filming of lithographic plate 10.For example, can use such paper: the paper that contains 100% wood pulp; Do not contain 100% wood pulp but contain the paper of synthetic pulp; The paper that on paper, has low density polyethylene layer; And similar paper.Specifically, under the situation that does not comprise synthetic paper, can reduce Master Cost.Like this, inset 14 can be with the low cost manufacturing.One of inset 14 more specifically example be such interleaving paper: it is made by bleached kraft pulp, and has 30 to 60g/m 2Basis weight, 0.7 to 0.85g/cm 3Density, 4 to 8% humidity and 4 to 6 pH value.Yet inset 14 is not limited thereto.
Lithographic plate 10 is had no particular limits with the process that forms lamination 12 in the thickness direction stack.Yet, as example, in a kind of lithographic plate process line, the lithographic plate of thin sheet form is being cut into preliminary dimension when it is vertically carried, generally be provided with an aggregation apparatus in the conveyor line, in order to lithographic plate 10 orders are flocked together.Like this, lamination 12 can superpose by this aggregation apparatus.In addition, have such situation on this manufacturing line, promptly the plate-shaped inset was disposed on the plate-shaped litho-paper and with the latter before cutting and contacts, and afterwards, the litho-paper of plate-shaped and inset are cut into predetermined size by integral type.In this case, lamination 12 forms in the accumulation process of aggregation apparatus, and wherein lithographic plate 10 is replacing each other with inset 14 and superposes.Certainly, lamination 12 also can be by this way, and promptly first lithographic plate 10 and inset 14 are being replaced superposes, and afterwards, the end of lithographic plate 10 is cut device or allied equipment cuts into same size.
The lamination 12 that so forms will be as shown in Figure 2 by inner packing paper 16 packings.Inner packing paper 16 is made of the paper with shading and anti-soak properties.After lamination 12 was isolated fully by inner packing paper 16 packings and with the external world, lamination 12 can be isolated with light reliably and be prevented to make moist.
The material of inner packing paper 16 has no particular limits, as long as lamination 12 can be packaged in wherein and isolate fully with the external world.Yet inner packing paper 16 can be made by for example non-BK bleached kraft of rectangle with preliminary dimension.In addition, craft paper can also use under such state, and the metallic film that promptly has predetermined thickness is applied on the paper, and under the situation of needs a resin bed with predetermined thickness is applied on the metallic film.In addition, craft paper also can use like this, promptly thickness be the low density polyethylene layer of 10 to 70 μ m attached on the above-mentioned metallic film, and thickness is that the black polyethylene film of about 70 μ m is attached on the low density polyethylene films, to improve shading and anti-soak properties.Generally speaking, the photosensitive printing version has ISO, even thereby be exposed under the faint light in the visible wavelength range, photo sensitive coating also can change.Therefore, galley need be isolated with light.In addition, also have such situation, promptly temperature-sensitive galley also can cause heat-sensitive layer to be degenerated because of the heat energy that applies in the light thereon, and its sensitivity is changed, and this depends on level of response.Therefore, wish that galley is isolated with light rightly.In addition, when humidity and temperature change suddenly, may cause problem, promptly galley may be degenerated because of photo sensitive coating or heat-sensitive layer dewfall, perhaps may adhere on the inset 14.Therefore, these galleys that need protection are not made moist.Inner packing paper 16 with said structure has fixing shading and anti-soak properties, thereby can prevent the photo sensitive coating and the heat-sensitive layer degeneration of lithographic plate 10, so that lithographic plate 10 is remained on constant quality.Certainly, if inner packing paper 16 can present above-mentioned shading and anti-soak properties, then low density polyethylene (LDPE), black polyethylene film and analogue are not must be attached thereto.
The shape of inner packing paper 16 and packaging structure, or the folding mode of wrapper have no particular limits, as long as can utilize inner packing paper 16 protection laminations 12 not make moist and isolate light.Yet, as example, the length of the long side 16L of inner packing paper 16 is made into predetermined length, so that two short side 16S of inner packing paper 16 can be under following state local overlap joint (seeing Figure 1B) each other, be the central authorities that lamination 12 roughly is placed in inner packing paper 16, wherein the long side 12L of the lamination 12 short side 16S that is parallel to inner packing paper 16 arranges (seeing Figure 1B), and inner packing paper 16 the long side 12L along lamination 12 folds from both sides.At this moment, inner packing paper 16 has constituted the shape of flat cylinder, so inner packing paper 16 is from outside unsettled the stretching out of each short side 12S of lamination 12, to form sponson 16H.
In addition, the length of the short side 16S of inner packing paper 16 is made into predetermined length, thereby by under the local each other state that is overlapping of short side 16S (seeing Figure 1B) sponson 16H is bent inwards from upside, from the top, folding sponson 16H will be overlapped on the lamination 12.Because lamination 12 is so by inner packing paper 16 packing, so lamination 12 can cover fully by inner packing paper 16, as shown in Figure 2.
At last, inner packing paper 16 be fixed device for example adhesive tape 38 stick on the desired location.Consequently, inner packing paper 16 is fixed and can unclamp accidentally or drop, and lithographic plate packaging structure 18 according to the present invention has just formed.
In having the lithographic plate packaging structure 18 of said structure, inset 14 is placed to such an extent that contact with filming, and it is impaired therefore can to prevent to film, and promptly so-called filming peeled off.In addition, the lamination 12 that is covered fully by inner packing paper 16 has shading and anti-soak properties, therefore is isolated from the outside.Like this, constitute lithographic plate 10 shading and the protection against the tide reliably of lamination 12.
When the lithographic plate of being packed by the lithographic plate packaging structure 18 of present embodiment 10 was used, at first, adhesive tape 38 was dismantled, so that inner packing paper 18 is opened.Afterwards, the lithographic plate 10 that is in lamination 12 forms is loaded into and has in the automatic platemaking machine or so-called type-setting machine for the version function.Perhaps, when needed, lithographic plate can be packed into by hand one by one.At this moment, in lithographic plate packaging structure 18 of the present invention, do not use traditional protection cardboard.Therefore, do not need to implement to remove the operation of protection cardboard, perhaps remove the operation that is used for the protection cardboard is fixed on the adhesive tape on the lamination 12.Consequently, lithographic plate 10 take out easily and the type-setting machine of packing in.
In addition, even after lithographic plate packaging structure 18 is opened, there is not discarded protection cardboard to exist yet.Therefore, no longer need to handle the protection cardboard, also do not need relevant expense.In addition, do not need the space that stores discarded protection cardboard, do not need yet and handle the discarded relevant labour cost of cardboard of protecting.
Because lithographic plate packaging structure 18 does not use the protection cardboard, so Master Cost can reduce.In addition, do not need the protection cardboard is placed on the desired location in the lamination 12, therefore pack the required time and expense also can reduce.
Lithographic plate packaging structure 21 according to second embodiment of the invention has been shown among Fig. 3.In lithographic plate packaging structure 21, lamination 12, and is further packed by a lithographic plate packing box 22 by inner packing paper 16 packings in the mode identical with lithographic plate packaging structure 18 among first embodiment again.In second embodiment, for convenience, the lamination 12 of packing is called inner packing lamination 18.
Expansion drawing from Fig. 4 in lithographic plate packing box 22, is adjoined each short side of a following table panel 24 and each short side of a upper surface panel 26 and is arranged that respectively a lamination forms bottom panel 28 and a lamination forms top panel 30 as can be seen.Each lamination forms on bottom panel 28 and the lamination formation top panel 30 and has formed multiple folding lines 32 respectively.When packing box 22 is assembled into state shown in Figure 3, by folding screw winding lap 34 and 36 of having formed of fold line 32.Like this,, also can protect the lithographic plate 10 that constitutes lamination 12 reliably, thereby can not occur splitting or problem that distortion etc. impacts quality even there is bigger power to be applied on the lithographic plate packing box 22 from the outside.In addition, on the lithographic plate packing box 22 gets an edition opening (upside) and is sealed by upper surface panel 26.By opening upper surface panel 26 as shown by arrow H, packing box 22 can be opened, thereby can take out lithographic plate 10.
Usually, lithographic plate 10 is formed as thin sheet form.Like this, after splitting or be out of shape in the bight of galley or side, occur such shortcoming easily, promptly image can thicken when developing, and perhaps printing ink can be applied brokenly when printing.Under not by the situation of outside lithographic plate packing box 22 packings, this impaired or distortion of lithographic plate 10 also can prevent by the lithographic plate packaging structure 18 among first embodiment.In the lithographic plate packaging structure 21 in second embodiment, lithographic plate 10 from outside packing, therefore can be prevented reliably that lithographic plate 10 is impaired by lithographic plate packing box 22.For example, even need do the conveying of long distance when handling lithographic plate 10, lithographic plate 10 also can not be subjected to damage that quality is impacted.In addition, inner packing paper 16 has lithographic plate 10 shadings and damp-proof function, and lithographic plate packing box 22 have the galley of preventing when being subjected to external force impaired or the distortion function.Therefore, lithographic plate 10 can utilize the proper packing unitized construction packing of the excellent function with protection lithographic plate 10.Consequently, lithographic plate 10 can be protected reliably.
In addition, lithographic plate 10 time does not use any protection cardboard in packing, and this is the same with lithographic plate packaging structure 18 among first embodiment.Therefore, take out the operation of lithographic plate 10 and lithographic plate packed into to have can easily implement automatically for the platemaking machine of version function or the operation in the so-called type-setting machine.In addition, do not need to implement the processing operation of discarded protection cardboard.Therefore, do not have the disposal cost of discarded protection cardboard, do not need the space that stores discarded protection cardboard yet.In addition, the Master Cost of lithographic plate packaging structure 21 and pack the required time or labour cost can reduce.
The material that constitutes lithographic plate packing box 22 has no particular limits, as long as it can prevent as previously mentioned that lithographic plate is not subjected to the external force effect.For example, when packing box was to be made by corrugated fibreboard, lithographic plate packing box 22 can come out with lighter weight and low-cost production.In addition, reclaiming or handle with the back of packing box is comparatively convenient, and this point is desirable.
Lithographic plate packaging structure 42 according to third embodiment of the invention has been shown among Fig. 5.In lithographic plate packaging structure 42, lamination 12 directly is packaged in the lithographic plate packing box 22 as among second embodiment, and not by inner packing paper 16 packings.
Like this, the same with lithographic plate packaging structure 21 among second embodiment in the lithographic plate packaging structure 42 of the 3rd embodiment, can prevent reliably that lithographic plate 10 is impaired.For example, even need do the conveying of long distance when handling lithographic plate 10, lithographic plate 10 also can not be subjected to damage that quality is impacted.
In the lithographic plate packaging structure 42 of the 3rd embodiment, do not use inner packing paper 16.Generally speaking, the corrugated fibreboard that constitutes lithographic plate packing box 22 has predetermined shading and anti-soak properties, and the bonding part of corrugated fibreboard under packed state can be sealed reliably by a shading piece, to keep required shading and anti-soak properties.Therefore, can prevent the degeneration of filming of lithographic plate 10.Adhesive tape 38 can be used as shading piece.
Lithographic plate 10 time does not use the protection cardboard in packing, and the lithographic plate packaging structure 21 among the lithographic plate packaging structure 18 among this mode and first embodiment and second embodiment is identical.Therefore, take out the operation of lithographic plate 10 and lithographic plate packed into to have can easily implement automatically for the platemaking machine of version function or the operation in the so-called type-setting machine.In addition, do not need to implement the processing operation of discarded protection cardboard, therefore do not have the disposal cost of discarded protection cardboard.In addition, do not need the space that stores discarded protection cardboard yet.In addition, the Master Cost of lithographic plate packaging structure 21 and pack the required time or labour cost can reduce.
The process of the lamination 12 of the lithographic plate packaging structure 130 packing lithographic plates 10 that utilize in the four embodiment of the invention has been shown among Fig. 6.Lithographic plate packaging structure 130 among the 4th embodiment has been shown among Fig. 7.
Lithographic plate packaging structure 130 is made of a carrier member 132, bight cover plate 134, surface cap 136 and clamping band 138.Carrier member 132 is so-called pallet or balladeur train, is used to load lamination 12 on it.Lamination 12 can be an inner packing lamination 158, can apply bight cover plate 134 and surface cap 136 on it.Clamping band 138 is used for bight cover plate 134 and surface cap 136 are fastened on carrier member 132.
Carrier member 132 has a bracket portion 146, wherein, has the upper plate 140 of essentially rectangular shape and lower plate 142 respectively and is being connected to each other by a plurality of elongated or box-shaped shanks 144.Formed an insertion portion 148 between the adjacent leg 144 respectively,, carrier member 132 can have been lifted by the fork on V shape lifting device or the manual lifting device is injected in the insertion portion 148.In Fig. 6 and 7, shank 144 promptly is made into elongated shape along the direction shown in the arrow D along the depth direction of bracket portion 146 respectively.Insertion portion 148 also is made respectively respectively and extends along the depth direction of bracket portion 146.Yet, as example, therefore shank 144 also can be divided into square along the direction shown in the arrow D, not only along the depth direction of bracket portion 146 but also formed insertion portion 148 along the horizontal of bracket portion 146, so that fork can insert from either direction.Laterally represent with arrow W.
On the upper surface of a upper plate 140 that is fixed on bracket portion 146 at the loading bearing 150 that has the approximate wedge shape shape on the end face.As can be seen, the upper surface that loads bearing 150 tilts towards upper plate 140, and has formed a loading surface 152 that is used to load lamination 12 from Fig. 6 and 7.
A plate shaped back plate 154 forms from the bottom of loading surface 152 is upwards upright.On the back plate 154 facing to the Surface Vertical of loading surface 152 in loading surface 152 and constituted an areal of support 156, be used to support the part of the load of the lamination 12 that is loaded on the loading surface 152.
Under the state that is loaded on the loading surface 152, lamination 12 is implemented inner packing by inner packing paper 16.The lamination that is under the inner packing state is called inner packing lamination 158 below 12.Figure 6 illustrates mono-lamination 12, but a plurality of laminations 12 that also can superpose out continuously.
In addition, in the 4th embodiment,, will arrange an inserted sheet 44 different with the thickness of inset 14 every the lithographic plate 10 of the formation lamination 12 of predetermined quantity.Inserted sheet 44 is as identification piece of the present invention.When seeing lamination 12 from the side, can visual discrimination go out the different of inserted sheet 44 and lithographic plate 10 or lamination 12.For this reason, when lithographic plate 10 is used, inserted sheet 44 usefulness can be marked, thereby can take out the lithographic plate 10 of predetermined quantity at every turn.Identification piece of the present invention is not limited to above-mentioned inserted sheet 44.Can use any identification piece, they are different with lithographic plate 10 or lamination 12 as long as can visual discrimination when seeing from the side go out.For example, can utilize the paper identical dyeing and make inserted sheet, thereby can not influence the quality or the operability of lithographic plate 10, perhaps inset can be gone out and constitutes inserted sheet from lamination 12 part omitted micro stretchings, to enable the person's of being operated identification with inset 14 structures.In addition, in first to the 3rd embodiment, also can arrange an identification piece every the lithographic plate 10 of the formation lamination 12 of predetermined quantity.
In the present embodiment, as inner packing paper 16, can use such craft paper, its size is enough to integral type and is loaded in single or multiple lamination 12 on the loading surface 152, and has applied aluminium foil or the metallic film of 6 to 7 μ m on it.When having loaded a plurality of lamination 12, they also can utilize inner packing paper 16 to pack separately.
A plurality of laminations 12 are implemented inner packing by inner packing paper 16 with integral form, and for example adhesive tape 38 is fixing and adhere on loading surface 150 and the back plate 154 for device and the end of inner packing paper 16 is fixed.Consequently, formed inner packing lamination 158.
Bight cover plate 134 has by a broad 162 and the roughly L shaped transverse shape that crevice 164 is formed, and is made into elongated shape on the whole.Broad 162 contacts are loaded in the front surface 158F of the inner packing lamination 158 on the loading surface 152, the side surface 158S of crevice 164 contact inner packing laminations 158.In addition, the length of bight cover plate 134 is made and is substantially equal to or greater than the short transverse size of inner packing lamination 158.
Surface cap 136 is formed as elongated shape, thereby has the thickness of the broad 162 that is equal to or greater than bight cover plate 134, and is arranged in basically on the lateral center part of front surface 158F of inner packing lamination 158.
Clamping band 138 has such length, promptly is enough to be wrapped on inner packing lamination 158, bight cover plate 134, surface cap 136 and the back plate 154 under bight cover plate 134 and surface cap 136 are applied to state on the inner packing lamination 158.Under the state that has so twined clamping band 138, by operating a clasp 166, clamping band 138 can be tightened gradually, and endogenetic process is on inner packing lamination 158, bight cover plate 134, surface cap 136 and back plate 154.Consequently, inner packing lamination 158, bight cover plate 134 and surface cap 136 can easily be fixed on the back plate 154.In the present embodiment, as example, the binding belt with predetermined length can be used as clamping band 138.
In the lithographic plate packaging structure 130 with said structure in the 4th embodiment, lithographic plate 10 vertically is loaded on the loading surface 152 by means of the effect of vertical direction element, and is parallel to areal of support 156 layouts.Therefore, be consistent basically no matter the quantity of lithographic plate 10 how, is in the short transverse size of the lithographic plate packaging structure 130 under the loading condition.Like this, as example, when storing lithographic plate packaging structure 130,, just can realize efficient storage, and can above lamination 12, not stay wasted space as long as can correctly determine the short transverse size of storage area.
In addition, lithographic plate 10 loads himself weight by this way, and promptly their lower edge entirely distributes along loading surface 152.Therefore, when lithographic plate 10 was loaded in the platemaking machine, for example by loading for version mechanism or allied equipment automatically, they can be loaded on the suitable loading position.In addition, lithographic plate 10 can be by lifting easily, the processing ease enforcement of therefore carrying and moving.
Loading surface 152 tilts towards upper plate 140, and lamination 12 loads with fixing inclined at inclination angles.A part of load of lamination 12 is supported face 156 and bears.Therefore, the load of lamination 12 is to be that bidirectional mode is born to be assigned to two modes in the plane.Therefore, when discharging from packing as described later, lamination 12 and lithographic plate 10 do not have the possibility of accidental fall or landing.
As shown in Figure 7, under packed state, bight cover plate 134 is applied on the front surface 158F and the bight between the side surface 158S of inner packing lamination 158, and these two surfaces of contact inner packing lamination 158.For this reason, though lamination 12 when carrying and store by any object from outer side collision, the bight that constitutes the lithographic plate 10 of lamination 12 also can be protected, and splits or is out of shape to prevent.In addition, even act on the lamination 12 from the fastening force of clamping band 138, fastening force also can be disperseed along short transverse by bight cover plate 134, and can not act directly on the bight of lithographic plate 10, particularly near clamping band 138 positions.Therefore, the bight of lithographic plate 10 can not be out of shape.In addition, even lithographic plate 10 has crooked trend under the fastening force effect of clamping band 138, but also can prevent lithographic plate 10 bendings, thereby lithographic plate 10 is remained on flat condition by surface cap 136.Certainly, lithographic plate 10 can not occur being out of shape or the situation of impaired danger under, bight cover plate 134 or surface cap 136 can be omitted, with the quantity of the parts that reduce to constitute lithographic plate packaging structure 130.In addition, bight cover plate 134 or surface cap 136 can be replaced by end plate or the top board that tradition is used.In other words, end plate is made into the size of the front surface 158F that is equal to or greater than inner packing lamination 158 substantially.Arrange with after front surface 158F contacts at end plate, it is concordant or protruding with inner packing lamination 158 basically that the neighboring of end plate is made.Consequently, can prevent that the side of inner packing lamination 158 or the neighboring that the bight is lithographic plate 10 are subjected to the external force effect, thereby prevent lithographic plate 10 distortion or impaired.
In the lithographic plate packaging structure 130 in the 4th embodiment, lithographic plate 10 also uses the protection cardboard in when packing, and this is identical with the mode of lithographic plate packaging structure 18 among first embodiment.Therefore, can easily implement to take out lithographic plate 10 operation and with lithographic plate pack into have automatic for the platemaking machine of version function or the operation in the so-called type-setting machine.In addition, do not need to implement the processing operation of discarded protection cardboard, thereby do not have the disposal cost of discarded protection cardboard, do not need the space that stores discarded protection cardboard yet.Therefore, do not need and handle discarded relevant expense or the labour power of cardboard of protecting.In addition, the Master Cost of lithographic plate packaging structure 130 and pack the required time or labour cost also can reduce.
In the 4th embodiment, the lithographic plate 10 that is loaded on the carrier member 132 is not limited to above-mentioned inner packing lamination 158.For example, lithographic plate packaging structure 42 among lithographic plate packaging structure 21 among second embodiment or the 3rd embodiment, that is to say, with the structure of lithographic plate 10 external packings in lithographic plate packing box 22, also can use and be loaded on the carrier member 132, to form the 4th the lithographic plate packaging structure 130 among the embodiment.
In the 4th embodiment, the example that the lamination 12 of lithographic plate 10 is loaded in the structure on so-called pallet or the balladeur train has been described.Yet the filling structure of lamination 12 is not limited thereto.For example, single or multiple lamination 12 can be loaded on common pallet or the balladeur train, and pallet or balladeur train do not comprise the above-mentioned loading bearing 150 that constitutes wedge-type shape on end face, perhaps do not comprise back plate 154.In addition, lithographic plate 10 can flatly be superimposed upon on the such pallet or balladeur train.For example, when lithographic plate 10 is smooth when being superimposed upon on the balladeur train, wherein load bearing 150 and back plate 154 and removed from the carrier member shown in Fig. 6 and 7 132, then the stack of lamination 12 makes lithographic plate 10 be parallel to upper plate 140 to settle.
The material of pallet or balladeur train has no particular limits, as long as it has required intensity.The example of material comprises: timber, metal, corrugated fibreboard, cardboard, cellular structural material and like that.
Be used for the anchor fitting that lamination 12 is fixed on pallet or the balladeur train is not limited to said fixing band 138.For example, can use such structure, promptly the film that can shrink under controlled condition is wrapped on lamination 12 and pallet or the balladeur train, and lamination 12 is fixed on pallet or the balladeur train by means of the convergent force of film.The shrinkable film that the example of this film shrinks when being included in temperature traverse, but the present invention is not limited thereto.
Lithographic plate packaging structure 232 according to fifth embodiment of the invention has been shown among Figure 10.The forming process of lithographic plate packaging structure 232 has been shown among Fig. 8 and 9.Lithographic plate packaging structure 232 constitutes by this way, the lamination 12 that is lithographic plate 10 is loaded on the lithographic plate carrier member 234, a top board 236 is placed on the lamination 12, in addition, lamination 12, carrier member 234 and top board 236 constrain in together by resin system fixed strip 238.Lithographic plate carrier member 234 is hereinafter to be referred as making " carrier member 234 ".
In addition, lithographic plate 10 among the 5th embodiment, the lithographic plate in all aforementioned (1) to (11) just, can be loaded onto on the carrier member 234 of the present invention, to form lithographic plate packaging structure 232, this and lithographic plate are how to supply with irrelevant, and it is automatic for the supply of version mechanism to consider that promptly they are utilized by the user, or supplied with by the user is manual, still otherwise supply with.
In addition, in lithographic plate, have a so-called useless version or useless version, for the reason of paper, it is arranged on (being non-Printing Zone) on the position that does not apply printing ink, and this is by used printer type decided.This useless version or useless version are also contained in according in the lithographic plate 10 of the present invention.
As can see from Figure 8; the lamination 12 of lithographic plate 10 forms by this way; promptly be used to protect the inset 14 of filming alternately to superpose along thickness direction with lithographic plate 10; and protection cardboard 222 is arranged on two end faces of stack on the direction; perhaps every lithographic plate 10 stacks of predetermined quantity, so the structure that constitutes is had the inner packing paper 250 enforcement inner packings of predetermined shading and anti-soak properties.According to the type of lithographic plate 10, can form one or more insets 14 in the lamination 12 of lithographic plate 10, and protection cardboard 222 can be removed.
When lamination 12 is made of two coating lithographic plates, below inset 14 is arranged in Fig. 8 between lithographic plate 10 and the protection cardboard 222.Like this, the quantity of inset 14 is than more than 10 one of lithographic plates.Consequently, do not have the possibility of direct contact protection cardboard 222 of filming of lithographic plate 10, thus can prevent because of film and filming of protecting that cardboard 222 direct contacts cause impaired.
In addition, can use such protection cardboard 222: it is made by waste paper and has 200 to 1500g/m 2Basis weight, 0.7 to 0.85g/cm 3Density, 4 to 8% humidity, 3 to 20 seconds Bake smoothness and 4 to 6 pH value.For example, when lamination 12 is made of 10 to 100 Zhang Ping's lithographic printing plates 10, lithographic plate 10 and protection cardboard 222 can by anchor fitting for example adhesive tape fix so that they can not misplace each other.
Lithographic plate 10 is had no particular limits with the process that forms lamination 12 in the thickness direction stack.Yet, as example, in a kind of lithographic plate process line, the lithographic plate of thin sheet form is being cut into preliminary dimension when it is vertically carried, generally be provided with an aggregation apparatus in the conveyor line, in order to lithographic plate 10 orders are flocked together.Like this, assemble lithographic plate, can form lamination 12 by this aggregation apparatus.In addition, have a lot of such situations on this manufacturing line, promptly the plate-shaped inset was positioned to contact sheet shape litho-paper before cutting, and afterwards, the litho-paper of plate-shaped and inset are cut into predetermined size by integral type.In this case, lamination 12 forms in the process of utilizing aggregation apparatus to assemble, and wherein lithographic plate 10 is replacing each other with inset 14 and superposes.Certainly, lamination 12 also can form in the following manner, and promptly after lithographic plate 10 and inset 14 were replacing stack, the edge of lithographic plate 10 is cut device or allied equipment cuts into concordant shape.
The lithographic plate 10 of Gou Chenging, inset 14 and protection cardboard 222 are packed by inner packaging material 250 as previously mentioned.Inner packaging material 250 is made of the paper with shading and anti-soak properties.Because lithographic plate 10 is packed by inner packaging material 250 and is isolated from the outside fully, so lamination 12 can be isolated with light reliably and prevented to make moist.
The material of inner packaging material 250 has no particular limits, as long as lamination 12 can be packaged in wherein and isolate fully with the external world.Yet inner packaging material 250 can be made by for example non-BK bleached kraft of rectangle with preliminary dimension.In addition, craft paper can also use down by state below, and the metallic film that promptly has predetermined thickness is applied on the paper, and under the situation of needs a resin bed with predetermined thickness is applied on the metallic film.In addition, craft paper also can use like this, and promptly thickness is that the low density polyethylene layer of 10 to 70 μ m adheres on the above-mentioned metallic film, and thickness to be the black polyethylene film of about 70 μ m adhere on the low density polyethylene films, to improve shading and anti-soak properties.Generally speaking, the photosensitive printing version has ISO, even thereby be exposed under the faint light in the visible wavelength range, photo sensitive coating also can change.Therefore, galley need be isolated with light.In addition, also have such situation, promptly temperature-sensitive galley also can cause heat-sensitive layer to be degenerated because of the heat energy that applies in the light thereon, and its sensitivity is changed, and this depends on level of response.Therefore, wish that galley is isolated with light rightly.In addition, when humidity and temperature change suddenly, may cause problem, promptly galley may be degenerated because of photo sensitive coating or heat-sensitive layer dewfall, perhaps may adhere on the inset 14.Therefore, these galleys that need protection are not made moist.Inner packaging material 250 with said structure has fixing shading and anti-soak properties, thereby can prevent the photo sensitive coating and the heat-sensitive layer degeneration of lithographic plate 10, so that lithographic plate 10 is remained on constant quality.Certainly, if inner packaging material 250 can present above-mentioned shading and anti-soak properties, then low density polyethylene (LDPE), black polyethylene film and analogue are not must be attached thereto.
The shape of inner packaging material 250 and packaging structure, or the folding mode of wrapper have no particular limits, as long as can utilize inner packaging material 250 protection laminations 12 not make moist and isolate light.
As shown in Figure 9, anchor fitting for example adhesive tape 52 be applied on the desired location on the inner packaging material 250.Consequently, inner packaging material 250 is fixed and can unclamp accidentally or drop, and like this, lamination 12 has just been finished.Anchor fitting has no particular limits, as long as it can be fixing with inner packaging material.For example, can instead of adhesive tape 52 such as adhesive agents such as hot melt adhesive or pastes or use with adhesive tape.
As shown in Figures 8 to 10, carrier member 234 has tabular bearing 240.Lamination 12 is loaded on the bearing 240.Lithographic plate 10 is parallel to bearing 240 and loads.It is so-called flat folded that Here it is.
Shank 242 is set to from bearing 240 and stretches out downwards, and the space that is formed between bearing 240 and its installation surface can be used as insertion portion 248.Inject in the insertion portion 248 by the fork on for example V shape lifting device or the manual lifting device, carrier member 234 and packaging structure 232 can be lifted.The quantity of shank 242 and position and material therefor thereof have no particular limits, and need only their bearing supports 240 reliably.In the present embodiment, four shanks 242 are located at respectively near the bight of bearing 240.As example, can a shank 242 be set in that the every side central authorities of bearing 240 are additional respectively, to prevent bearing 240 bendings reliably.In addition, the shape or the material of bearing 240 have no particular limits, as long as its intensity can prevent unexpected deflection or cause warpage under the state that has loaded lamination 12.
A top board 236 is placed on the upper surface of the lamination 12 that is loaded on the carrier member 234.Top board 236 is formed as a plate, and the upper surface that its size was slightly larger than or was substantially equal to lamination 12 is a lithographic plate 10.Even there is external force to affact on the lamination from the upside of lamination 12, its energy also can be absorbed by top board 236, thereby in the degree that the limit deformation of lithographic plate 10 can not be gone wrong actually.
When the size of top board 236 equated with lithographic plate 10, top board 236 was to settle like this, and the lithographic plate 10 that promptly is arranged on the upper surface of lamination 12 can not reach outside the top board 236.In this case, lithographic plate can be protected reliably, and this point is desirable.Yet too big if top surface 236 is made, when the top side is seen, it will reach outside the carrier member 234, thereby operating efficiency is reduced.Therefore, from the angle of being convenient to operate, top board 236 preferably must not seen from the top side by moulding and can be reached outside the carrier member 236, that is to say, moulding must equate with carrier member 234 sizes at most.
Lithographic plate packaging structure 232 of the present invention is to form like this, and promptly a resin system fixed strip 238 is wrapped on carrier member 234, lamination 12 and the top board 236 fully in the single-piece mode.Like this, carrier member 234, lamination 12 and top board 236 can integral operations, and can unexpected dislocation or unclamp.
The quantity of fixed strip 238 and position can be determined aptly according to the shape of lamination 12 or size.In the present embodiment, the upper surface shape that can suppose lamination 12 is that the shape of lithographic plate 10 is formed as roughly square.Therefore, can arrange four fixed strips 238 altogether, so that they are intersected with each other.
The short side 236S that two brace panels 244 are parallel to top board 236 is arranged on the upper surface of top board 236, and two other brace panel 246 is parallel to long side 236L and is arranged on the upper surface.For example adhesive agent or screw nail are fixing by anchor fitting for these brace panels.The brace panel 244 that is parallel to short side 236S layout must be had and short side 236S equal lengths by moulding respectively, and this length makes it to extend to another from a long side 236L.On the other hand, the brace panel 246 that is parallel to long side 236L layout is shorter than long side 236L respectively, and is clipped between the brace panel 244.These brace panels 244 and 246 are fixed on the desired location, thereby corresponding with fixed strip 238 when top board 236 is seen in the top side.Because these brace panels 244 and 246 effect, to compare when having only top board 236 to use, the integral rigidity of top board 236 and brace panel 244 and 246 can increase.
In addition, the shape of brace panel 244 is to determine that so promptly fixed strip 244 can not touch top board 236 near the short side 236S of top board 236. Brace panel 244 and 246 width W 1 are made the width W greater than fixed strip 238.Like this, compare during with fixed strip 238 direct contact top boards 236, the constrained force of fixed strip 238 when settling by means of brace panel 244 and 246 can be distributed in the broad zone and affact on the top board 236.
As previously mentioned, in the lithographic plate packaging structure 232 in the 5th embodiment, the lamination 12 that is made of a plurality of lithographic plates 10 is loaded on the carrier member 234, even therefore a large amount of lithographic plate 10 also can be operated in the single-piece mode.Integral type constrains in together by fixed strip 238 for carrier member 234, lamination 12 and top board 236, so they can unexpectedly not misplace and unclamp.In addition, bearing 240 and top board 236 are arranged on two end faces of lamination 12 along the stack direction respectively.Therefore, can prevent the distortion of lithographic plate 10, impaired and degeneration.
In addition, different with conventional confguration is not have bolt to be used for carrier member 234, lamination 12 and top board 236 integral types are constrained in together.Therefore, do not need the operation of binding bolt, and packaging operation can be finished with littler labor content in the shorter time.The operation that utilizes fixed strip 238 constraint also can by normally used restraint device for example automatic flexible strapping machine implement, when using restraint device, packaging operation can further be finished with littler labor content in the shorter time.
Even lithographic plate packaging structure 232 when being opened, only utilizes cutting knife to cut off fixed strip 238 and just can realize taking apart, the form of cutting knife depends on the type of fixed strip 238.Consequently, operating efficiency is improved.
Constrain under together the state fixed strip 238 main contact brace panels 244 and 246, and contact top board 236 on very little part only in carrier member 234, lamination 12 and top board 236 bar 238 integral types that are fixed.The constrained force of fixed strip 238 mainly acts on the top board 236 by brace panel 244 and 246.When the integral rigidity of top board 236 and brace panel 244 and 246 is higher than only with top board 236.Therefore, can prevent to cause top board 236 bendings because of the constrained force of fixed strip 238.Specifically, if top board 236 is made the upper surface greater than lamination 12, then when the constrained force of fixed strip 238 acted on top board 236 sides, top board 236 easy upwards warpages bloated.Yet the present invention can easily prevent top board 236 warpages.In addition, because brace panel 244 and 246 width be greater than fixed strip 238, thereby can alleviate the concentration of local of the constrained force of fixed strip 238, and prevent top board 236 local dents.Like this, can prevent top board 236 crooked or depressions, and therefore keep restrained condition reliably.
In addition, even, neither make the thickness of top board 236 bigger in order to prevent top board 236 crooked or formation pits.For this reason, constraint manipulation and take operation apart can be by lightweight top board 236 and easily implement.Lithographic plate packaging structure 236 also is a lightweight, so its conveying is also very convenient.
The shape of top board, the quantity of reinforcement, position and shape, and the quantity of fixed strip and position, be not limited to previously described those.In other words, the suitable number of each said elements, shape and position are that the size according to lamination 12 is that the intensity of the size of lithographic plate 10 and quantity, required constrained force and the reinforcement that is provided with corresponding to constrained force is determined.Their example is following to be described as the 6th to the 8th embodiment.In each embodiment, represent with identical Reference numeral with essentially identical element and parts among each embodiment of front, and no longer describe them.
