Description
Technical field
The present invention relates to a kind of newspaper offset rotary press that utilizes silk screen (ウ エ Block) and at Printing Department's printing cylinder that be provided with, that be used to install forme of newspaper offset rotary press.
Background technology
In the printing of the polychrome printing product that use offset rotary press, condition is by the relative printing surface of image not being misplaced, can obtaining distinct and good printing.
, in the printing of polychrome printing product, exist following problem.Under the situation of the rotary press that uses silk screen, particularly the polychrome printing product exist the tendency that tower assembly ( ワ-コ ニ Star ト) is changed at present, during printing, dumping processing solution traps when the character of the width of silk screen and silk screen self and printing etc. are relevant, and so-called fan widens phenomenon can take place.The fan widens phenomenon is, when the paper along the machine center walking passes through blanket cylinder, in the phenomenon that laterally stretches a little.Because of this fan widens phenomenon, the pattern of printing surface can become in per 1 look all the printing towards the off(-)center of walking paper.Except factor like this, the error on variation, plate-making error or the machinery production of the various conditions when also comprising printing, a variety of causes such as error when forme is installed as the reason of alignment dislocation.
Fig. 7 is the key diagram that the reference position of forme is in the past set.At this, the situation of growing the printing cylinder of the wide forme of 2 pages, 1 page girth, 4 pagewidths with 1 page is illustrated.
(1) uses the photonasty material is coated the PS version as forme (Pre-Sensitized Plate) on the supporting mass, do not have on the ablated unprocessed forme 1 in newspaper paper content, form the locating hole 2a of zero shape and the locating hole 2b of shape, simultaneously, relative upside of the central authorities of 1 pagewidth in 2 pagewidths and downside form as the breach 2c of 2 place's benchmark and the breach 2d of 2 place formes location usefulness.Breach 2c, 2d and locating hole 2a, 2b makes (with reference to Fig. 7 (a)) by machines such as plate perforators.
(2) similarly, on the egative film (negative film) 3 of the paper that has duplicated newspaper, on the position identical, also form the locating hole 2a of zero shape and the locating hole 2b of shape with the locating hole 2b of the locating hole 2a of zero shape of forme and shape.With the locating hole 2a of zero shape and the locating hole 2b of shape is benchmark, and forme 1 is overlapped with film 3 alignments, finishes the forme (with reference to Fig. 7 (c)) of ablating.
(3) then, for the forme 1 that will finish is installed on the printing cylinder, carry out the bending machining (with reference to Fig. 7 (d)) of the version of the distolateral and pinching end opposition side of the clamping of forme.
Fig. 8 illustrates forme and is installed to the view under the state on the printing cylinder.As shown in Fig. 8 (b), will clamp distolateral and the pinching end opposition side inserts and is installed among the crack groove 7a of printing cylinder 7 for the installation of forme 1 on the printing cylinder 7.
When the printing cylinder of 4 pagewidths is considered to be assigned to the driving side of 2 pagewidths and fore side, 2 alignment pins (locating piece) 10a that is fixedly installing respectively, 10b embeds the 4 breach 2c of place that are provided with by aforementioned (1), among the 2d, produces the reference position.In addition, with the 4 breach 2c of place, the relevant ground of 2d will be towards the breach 2c in the left side of forme 1 as the reference position.In addition, the forme breach of 2 pagewidths is arranged in per 1 pagewidth with the breach of its relative up and down center as the reference position, from consideration easy to use, can the left and right sides any one as benchmark.Any one alignment pin of the left and right sides becomes benchmark.Towards the left side, but that be arranged to the width that is positioned at the alignment pin 10a on the printing cylinder 7 is roughly the same, just in time chimeric by the width that becomes the breach 2c of benchmark in this direction for the breach 2c that becomes benchmark, to obtain the reference position.The breach 2d of one side's forme location usefulness is different with the breach 10a that becomes benchmark, is arranged to and the chimeric broad width of alignment pin 10b that does not become the alignment pin benchmark.
In the past, be provided with and as described above forme correctly be installed on benchmark on the printing cylinder, particularly when making the printed matter that monochrome or polychrome printing coincide, requiring has tens of microns precision, and it is very important that the reference position becomes.For this reason, utilize the pin-and-hole open on the central portion up and down of forme, produce the reference position in the mode of the alignment pin (locating piece) that embeds printing cylinder.So, in the plate-making process of newspaper, adopted consistent pin system (pin alignment system).In addition, the alignment pin that is installed on usually on the printing cylinder is fixed, and the method that adopts mobile printing cylinder self to wait is regulated in the dislocation of alignment.
For this reason, method as the dislocation of the adjusting alignment on the printing cylinder horizontal plane, be in the past adopt to adjust printing cylinder and the forme that is mounted thereon between the position so that the method that image does not misplace, its concrete method is by records such as Japanese kokai publication sho 62-156954 communique, Japanese kokai publication hei 7-241976 communique, Japanese kokai publication hei 8-192507 communiques.For example, in Japanese kokai publication sho 62-156954 communique, the alignment plate moves towards axis direction by the horizontal register adjusting device, and variable forme is installed the reference position of usefulness.That is to say, when assembling makes alignment pin to device that axial grade moves, just regulate in advance with the alignment magnitude of misalignment.
But, in the printing cylinder of rotary press, dwindle half degree by the mounting groove gap that makes forme, in the narrow gap of the vibration when propelling alleviates printing, overlap mutatis mutandis device and fit into printing cylinder inside, the all complex structures that comprise processing must be made, the obstacle of cost or maintenance overhaul aspect can not be ignored.Particularly the groove of printing cylinder is that the slit type does not promptly have hemming device etc., just makes groove that the forme two ends embed to install when the axis direction of printing cylinder is provided with, its setting difficulty (with reference to Fig. 8 (b)) more that becomes.
In addition, in order to save in the space of realizing rotary press, with the printing cylinder of rotary press during as 1 times of cylinder (pact of 2 times of cylinders half diameter), in 1 times of cylinder, the space that the register adjusting device of assembling complexity is in the past used is not rich, and it is provided with has more increased difficulty.
In addition, though it is relevant with the reference position of the installation of correctly carrying out forme, but at this, be at 1 page girth, it is long that (driving side and fore side) installed 21 pages about on the printing cylinder of 4 pagewidths, the forme that 2 pages are wide, in the method relevant in the past with the forme reference for installation, owing to be installed on the forme occasion in the past about on the printing cylinder this, benchmark must be determined in the breach at 2 places of forme, in any one party of the left and right sides (when for example the forme of driving side is benchmark with the breach towards the left side, the forme of fore side also is the present situation of benchmark utilization with the breach towards the left side), therefore when being provided with adjusting device, must be arranged to extend to the position of the end face that leaves printing cylinder.The reason that device seen in this just previous disclosed communique complicates.
In addition, usually, the printing cylinder in the newspaper offset rotary press is the cylinder body that forme is housed, and mechanism that forme is fixed on the allocation etc. is housed.In addition, with inking roller or damping roller etc. contact, the space of a whole page is accepted printing ink or dumping processing solution, printing ink is transferred on the blanket cylinder that the rubber mass felt pan is housed, so that the walking paper that passes through is printed.
The size that is used for the forme of newspaper printing has long * 2 pages wide (2L2W) of 2 pages, long * 1 page wide (2L1W) of 2 pages, and long * 1 page wide (1L1W) of 1 page uses 2 pages long in Japan mostly.Printing cylinder in the rotary press of this newspaper offset is generally 2 page girths, 4 pages are wide, is called 2 times of printing cylinders, this be known (below, be called " 2 times of cylinders ").Along say with being with, the 22 wide forme modes of long * 2 pages of the page are housed on 2 times of cylinders usually use.
In addition, Fig. 9 is cut apart tectosome (shell type structure) for holding as the mechanism of alignment adjustment usefulness on 2 times of cylinders in the past.Cut apart tectosome and constitute, the register adjusting device 19 of above-below direction (circumferencial direction), left and right directions is housed in separately by driving side printing cylinder 11a and fore side printing cylinder 11b.As the reason of cutting apart tectosome be the alignment dislocation when its maximum purpose is the revisal printing.The variation of the various conditions when the alignment dislocation comprises printing, the error of plate-making or the error on the machinery production, the reasons such as error when forme is installed.Much less, not when cutting apart tectosome, descend move left and right up by making printing cylinder self, can realize alignment adjustment to a certain degree., in view of the multicolor tendency of in recent years printing, adopted the form of adjusting the left and right sides printing cylinder of cutting apart respectively as means of carrying out the alignment adjustment more accurately.In addition, adjust for this alignment, also known a kind of register control adjusting device, this device is, will be in the past the operator by visual judgement printing registration magnitude of misalignment and pass through action button, the mode of the dislocation of the above-below direction of revisal printing cylinder and the dislocation of left and right directions, with read by scanner be printed onto advance on the silk screen alignment mark and automatically adjust alignment adjustment up and down with this as benchmark according to the magnitude of misalignment of alignment.
In common offset rotary press, the reason that makes printing cylinder become 2 times of cylinders is, the printing cylinder of rotary press is in operation, contact with blanket cylinder or rubber cylinder, the strong transfer printing that transfer printing due to these cylinders is used is depressed, the high speed rotary while pushing, wherein, in order to print normally, printing cylinder must have the rigidity of bearing these factors.
, when printing cylinder was 2 times of cylinders, because of diameter is bigger, rotary press self was just huger, exists the tendency that tower assemblyization is arranged of carrying out polychrome rotary press at present, and rotary press self is difficult to densification and saves the space.
In addition, become 2 times of cylinders, forme also must have 2 pages long, and the problem of making as printing cylinder exists the problem that the cost of number time etc. of fee of material and processing printed cylinder increases.In addition, owing to be 2 times of cylinders, machinery weight also can increase, and the electric power consumption that drives this member also has to increase.
In order to solve aforesaid problem, consider that by making the printing cylinder of 1 page girth, 4 pagewidths (below be called " 1 times of cylinder ") diameter that makes printing cylinder is half of diameter of 2 times of cylinders.; diameter is half words of 2 times of cylinders; the printing cylinder of rotary press is in operation and contacts with blanket cylinder or rubber cylinder; thus; obviously owing to be high speed rotary when pushing with brute force; thereby the printing cylinder that not only normally prints does not therebetween have enough rigidity, and this cognition of printing cylinder phenomenons such as deflection takes place, the transfer printing pressure that very difficult acquisition is stable.Particularly, as the alignment adjustment usefulness that adopts existing 2 times of cylinders cut apart tectosome the time because the structure of printing cylinder body becomes fragile, the phenomenon of its deflection etc. is more obvious.
In addition, deflection except above-mentioned printing cylinder body, mechanism's part, so-called non-print range (gap) that each edition of printing cylinder and blanket cylinder and rubber felt pan are housed are faced mutually, also can be subjected to the fall influence of phenomenon (jumps) of temporary transient transfer printing pressure-off, have more increased the instability of transfer printing pressure.And then, the possibility of printing cylinder self breakage must be arranged.
Summary of the invention
For this reason, the invention provides the simple mechanism of a kind of usefulness just can move the reference position change that is installed to not the forme on 1 times of printing cylinder of spatial margin of the complicated register adjusting device of assembling, simultaneously, can make the newspaper offset rotary press in rotary press self compactness, saving space.
