Description
Technical field
That the present invention relates to when putting, be provided with and be sealed into and make the transfer roller rotating shaft pass and take shape in through hole and the axle sealing structure between the transfer roller rotating shaft in the drying baker and use the drying unit ground of this axle sealing structure of employing to dry the lithographic printing-plate manufacture method of the coating fluid on the substrate of coating lithographic printing-plate corresponding to drying baker ground by transfer roller supporting by the oven dry thing.
Background technology
As traditional axle sealing structure, illustrate the structure that the drying baker corresponding to the drying unit of lithographic printing-plate manufacturing installation is provided with.
In graphic arts process (comprising the electrofax graphic arts process) in recent years, lithographic printing-plate is used widely with can realizing making a plate process automation easily.Lithographic printing-plate is normally so made, promptly on substrates (aluminium strip) such as sheet or web-like aluminium sheet, surface treatments such as polish in for example independent or appropriate combination ground, anodic oxidation, silicate processing, other Combined Processing, constitute the coating and dry processing of the coating fluid of photosensitive layer or heat-sensitive layer (following general designation coated film) subsequently, then, cut into ideal dimensions.To this lithographic printing-plate expose, plate-making such as development treatment, gluing are handled and it is installed on the printing machine, under the situation of coating printing ink, printing on paper is literal, image etc. down.
As shown in Figure 4, the drying unit 112 that the coating fluid on the substrate is coated in oven dry has drying baker 114, in drying baker 114, blows high temperature air by unshowned air blast.The rotating shaft 124 of transfer roller 116 pass drying baker 114 sidewall 114A be projected into the outside and by bearing arrangement 118 supporting.Aluminium strip is carried on transfer roller 116 in drying baker 114, at this moment, transfer roller because of aluminium strip and transfer roller 116 mutually mutual friction rotate.
Sealing plate 126 has been installed on the outer surface of drying baker 114.On sealing plate 126, formed through hole 128, when not stoping rotating shaft 124 to be rotated, sealed between drying baker 114 and the rotating shaft 124 with internal diameter more bigger than rotating shaft 124 external diameters.
The dust intrusion inside outside drying baker 114 but, when so between through hole 128 and rotating shaft 124, having formed little gap, can not seal these spaces fully, on I'm afraid that also meeting is attached to aluminium strip.
Therefore, although preferably dwindle gap between through hole 128 and the rotating shaft 124, when dwindling very much, for example make the occasion of drying baker 114 and rotating shaft 124 distortion because of the heat in the drying baker 114 under, rotating shaft 124 contacts with sealing plate 126 and has hindered the rotation of rotating shaft 124.Rotating shaft 124 is worn and torn because of contacting with sealing plate 126, and the wearing and tearing break flour probably can be invaded in the drying baker 114, thereby described gap just can not dwindle on certain limit.
On the contrary because drying baker 114 internal gas pressures keep slightly highlyer than extraneous, produced from the drying baker 114 to the weak gas flow of outside, consider that also dust do not invade in the drying baker 114.
But, when producing such air-flow, the heat in the drying baker 114 also is lost to the outside, and efficiency reduces.

The drying unit 22 that is arranged on the downstream of each apparatus for coating 20 has the drying baker of establishing along aluminium strip 12 throughput directions respectively 46.In the drying baker 46, unshowned warm braw feeding mechanism is carried warm braw, thereby has dried coating fluid.In a plurality of drying units 22, set corresponding to drying condition ground separately supplying with the hot blast temperature of drying baker 46 and along the length of drying baker 46 throughput directions etc.
As Fig. 2 in detail shown in, in drying unit 22, the sidewall 46A (in Fig. 2, the side's wherein of only having drawn sidewall 46A and omitted the opposing party) that is set up in drying baker 46 upward is being provided with transfer roller 30.As shown in Figure 3, aluminium strip 12 on transfer roller 30, when carrying aluminium strip 12, rotates transfer roller 30 by friction (promptly not bearing the power from power source) between aluminium strip 12 and the transfer roller 30 with predetermined angle overlap θ local volumes, promptly becomes so-called free roller.This angle overlap θ is, refers to when when the direction of transfer roller 30 center line C is seen, the either party ground that prolongs the aluminium strip 12 that is positioned at transfer roller 30 both sides imagines and extended line L that the angle that this extended line L and aluminium strip 12 are handed over is exactly angle overlap θ.
Outside rotating shaft 28 is projected near the two ends of transfer roller 30.The outside that through hole 48 ground that take shape on the sidewall 46A are projected into sidewall 46A is passed in rotating shaft 28, and bearing arrangement rotatably support respectively protuberance.
Having relatively as illustrated in fig. 2 at the bearing arrangement 14 of an end upper support rotating shaft 28 of transfer roller 30, bearing housing 24 is supporting the thrust bearing 16 of transfer roller 30 (rotating shaft 28) rotationally.In addition, between thrust bearing 16 and bearing housing 24, be provided with the needle bearing 18 of axial (arrow J direction) mobile thrust bearing 16 within the specific limits.The outer ring (not shown) of needle bearing 18 is fixed on the bearing housing 24 by back-up ring 26.
Lubricating oil is by also lubricated thrust bearing 16 and needle bearing 18 in the bearing enclosed case 24, and it turns round these bearings smoothly.
On the contrary, though the bearing arrangement (not shown) of the other end (unshowned that side) the upper support rotating shaft 28 of transfer roller 30 relatively bearing housing support transfer roller 30 rotationally, it can axially immovably constitute.
Between bearing housing 24 and drying baker 46, the cover 50 of the axle sealing structure 32 that constitutes present embodiment is installed the protuberance of encirclement rotating shaft 28.Cover 50 and wholely roughly become cylindrical shape, the one end is fixed on the bearing housing 24, and the other end is fixed on the drying baker 46.Thus one, drying baker 46 keeps airtight conditions, and dust can not be invaded inside, and internal gas and high temperature air can not drain to the outside.
In addition, on cover 50, roughly the central authorities at axial (left and right directions of Fig. 2) have formed end difference 52, and the diameter of the other end is thicker than this end.Because end difference 52 distortion, an end of cover 50 (thin axial region) and the other end (thick axial region) are in directly upwards skew and flexible vertically easily of rotating shaft.
Then, the axle sealing structure 32 of present embodiment and the bearing arrangement 14 that axle sealing structure 32 is suitable for, the effect of drying unit 22 and the method for the coating fluid on the use drying unit 22 ground drying aluminium strip 12 are described.
The aluminium strip 12 that has been coated with coating fluid by apparatus for coating 20 from the teeth outwards is sent in the drying baker 46 of drying unit 22.In drying baker 46, aluminium strip 12 is by predetermined angle overlap θ contact transfer roller 30, and frictional force plays a role between these rollers, thereby transfer roller 30 is carried along with aluminium strip 12 and rotated.
In addition, in drying baker 46, unshowned warm braw feeding mechanism is sent into warm braw, thus dry aluminium strip 12 lip-deep coating fluids.
, according to present embodiment, surround the protuberance of rotating shaft 28 by covering 50 fully with bearing housing 24 here, the gap between rotating shaft 28 and the drying baker 46 is sealed (shaft sealer).Therefore, dust can not be invaded from the outside in the drying baker 46 and can not therefore have been kept the quality of aluminium strip 12 attached on the aluminium strip 12.Especially in lithographic printing-plate,, also cause quality to reduce, but according to present embodiment, it is high-quality that made lithographic printing-plate has also kept even if foreign matters such as small amount of dust adhere to from the teeth outwards.
In addition, because the heats in the drying baker 46 are not inadvertently gone to the outside, so just can dry the coating fluid of aluminium strip 12 reliably with heat still less.
In addition, do not rotate smoothly owing to hinder the rotation and the rotating shaft 28 of rotating shaft 28 and transfer roller 30, so transfer roller 30 has prevented that by not rotating relative to aluminium strip 12 with the friction of aluminium strip 12 aluminium strip 12 is injured with skidding.Especially, in the manufacturing installation of lithographic printing-plate, usually as the angle overlap θ ground setting low-angle of transfer roller 30 relatively (as 2 °≤θ≤5 °), the frictional force between aluminium strip 12 and the transfer roller 30 is little.In addition, even if angle overlap θ is big, tension force (pulling force of length direction) by acting on aluminium strip 12 etc. has dwindled frictional force between aluminium strip 12 and the transfer roller 30.Therefore, in the bearing arrangement 14 of present embodiment, as described above, owing to there is not painstakingly to hinder the rotation of rotating shaft 28, thereby under the little occasion of the frictional force between aluminium strip 12 and the transfer roller 30, can prevent reliably that also transfer roller 30 relative aluminium strips 12 from skidding, aluminium strip 12 is not easy injured.
In addition, when drying baker 46 and bearing arrangement 14 are set, even if be provided with at these offsetting has taken place on the position, rotating shaft 28 is not in contact with one another with drying baker 46 yet, thus the small position adjustments when not needing to be provided with, thus be provided with easily.
In addition, transfer roller 30 and rotating shaft 28 are because of the variations in temperature axial stretching in the drying baker 46.The other end of rotating shaft 28 can not move axially by unshowned bearing arrangement, thereby has only an end to move axially, and thisly moves through the needle bearing 18 that constitutes bearing 14 and is absorbed.Even if transfer roller 30 and rotating shaft 28 thermal expansions are not owing to thrust acts on the thrust bearing 16, so the resistance that transfer roller 30 is rotated does not increase.
In the above description, although cover 50 be rubber system situation under for example understand the examples that cover 50 is made of elastic component fully, an axial end but (being fixed on the part on the bearing housing 24) and the other end (being fixed on the part on the drying baker 46) relative displacement fully, unless necessary, otherwise not necessarily make by rubber all over.For example, such structure also is feasible, promptly when the elastic deformation material does not constitute cover 50 with metal and hard resin etc., roughly axially separately central, connects separately between each section with elastic components such as rubber.
Permission mobile means of the present invention also is not limited to elastic component (above-mentioned rubber etc.) and end difference 52, it also can be the plastic deformation parts, under the occasion that is elastic component, can make that relative position applies effect with returning primary position between rotating shaft 28 and the drying baker 46 by the reaction force of strain, this is preferred.In addition, on the flexible end at cover 50 by rubber only and the other end, obtain unless necessary, otherwise not necessarily to form end difference 52 under the occasion of rate of travel of necessity.
According to present embodiment, be rubber system fully if cover 50, then because shaft seal and elastic component (permission mobile means) are set integratedly, thereby do not cause the increase of number of components, can constitute axle sealing structure of the present invention at low cost.
In addition, although in foregoing invention as axle sealing structure suitable example of the present invention exemplified out the drying baker 46 of the drying unit 22 of lithographic printing-plate manufacturing installation, but the present invention is not limited to this, under the rotating shaft of transfer roller was projected into occasion outside the drying baker through hole, it can be applicable to occasion sealed between through hole and the rotating shaft.
In addition, as the principal element that relatively moves between rotating shaft and the drying baker, be not limited to the above-mentioned distortion that is caused by heat, for example, the distortion that is caused by cooling also is feasible, and the distortion and the displacement that are caused by external force also are feasible.
