Description
Technical field
The present invention relates to journalism printing equipment field, refer in particular to a kind of Gauss N75 and can print width report remodeling method and width report double width rotary press can be printed.
Background technology
Along with the appearance equipment operating of national energy-saving consumption reduction policy, how journalism people also saves energy and reduce the cost at thinking newspaper.Except reduction newspaper layout, reduction newspaper book size is also an important selection, like this except helping reader to read, more can save paper, win larger economic benefit chromatography, also claim in the industry this way for " newspaper weight reducing ".
Be born a kind of format specification of new-type newspaper for this reason, and its printing area (type page), at the newspaper of the row of 38.5 cm x 24 centimetres, 49.5 cm x 30 centimetres, 48 cm x 31 centimetres or 52 cm x 32 centimetres, is commonly called as " narrow report ".Narrow report originates from America and Europe, is conveniently to read at narrow or mobile space and design, and such as at train, when bus being read newspaper, after the old-fashioned space of a whole page launches, width is too wide, affects other people, and inconvenience is read.The shape of being convenient to read conveniently can be folded into after changing narrow report into.Domestic appreciiable newspaper also uses this ratio (roughly meeting 1:0.615) as The Beijing News when correcting, city bulletin, Chongqing Times, Beijing Youth Daily etc.
And be suitable for conveniently except promoting, adopt narrow paper printing in theory, paper 5.2%-12.9% can be saved.As adopted 1360mm double width newsprint, compared with 1562mm newsprint, paper is saved amplitude and is: (1562-1360)/1562 × 100%=7.81%.If the year paper using amount of a newspaper office is 20,000 tons, then can save paper using amount about 0.16 ten thousand ton printing market, cost is roughly equal to Renminbi 7,200,000 yuan (by 4500 yuan/ton).
Therefore, from the broad prospect of application of energy-saving and cost-reducing and environmental angle narrow report in addition, in current journalism, the printing of narrow report becomes a megatrend already.
On the other hand, printing equipment in using in Traditional Newspapers generally includes single width rotary press, double width rotary press two kinds, wherein single width printing of rotary press is narrow gives the correct time, because space of a whole page picture and text line of centers overlaps all the time with forme line of centers, paper line of centers and machine center line (such as Fuji's starlight series), so the demand that the subsidiary such as nippin rolIer, pressure roller can meet narrow report printing only need be adjusted.
And it is quite different for double width rotary press, the particularly folding machine part of equipment, because two formes are equipped with in left and right on same cylinder, the line of centers of line of centers with forme just making space of a whole page picture and text, the line of centers of line of centers and set square splitting paper do not overlap, once the printing of narrow report will be changed, will go wrong.And Geng Duo newspaper office introduction in recent years is all double width rotary press, purchasing new equipment needs new wholesale to drop into undoubtedly, and existing equipment often can only be discarded, and wastes very much, so how will realize the printing of narrow report on existing double width rotary press is one of problem needing solution badly in the industry.

Detailed description of the invention
By describing technology contents of the present invention, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
For the double width rotary press Gauss N75 be common in journalism mentioned in background technology, in order to wide, the narrow report printing of different fabric width can be adapted to, the invention provides a kind of Gauss N75 and can print width report remodeling method, correspondence comprises reconstruction flow and printing adjustment flow process two parts.
Wherein, most crucial
reconstruction flowspecifically comprise:
According to desired level amount of movement, the part of adjacent one jiao of two set squares is cut, make this angle and set square be separated into the step of independently angle movable block 41 as shown in phantom in Figure 1.By the transformation of this step can to solve in original folding machine two set square relative displacemenies exceed design latter two set square corner of amount of movement 10mm can touch dieback and cannot be close again problem.And the width of angle movable block 41 under cutting and separating, the fabric width printing narrow report according to actual needs determines, as to during in requisition for print 1360mm double width newsprint, needs to cut away the wide angle movable block 41 of about 50mm.
The step that base station is placed with the perforate of the fixed mount of set square is widened according to desired level amount of movement.The perforate design amount of movement placing the fixed mount of set square due to former base station is limited, therefore in existing equipment, before two set squares will print close to meeting narrow report relatively, its fixed mount will cannot movement further to the verge of opening of base station because of top, therefore this step needs to widen perforate, the mode of widening can adopt and widen open bulk, also can adopt the method only will can blocked fixed mount movable part (diagram dotted portion) in platform 102 during base station 100 is between two set squares and cut off as shown in Figure 4.Thus make fixed mount can meet the demand needing parallel motion amount.
The step of the limit switch spacing of corresponding fixed mount is changed according to desired level amount of movement.Corresponding original equipment does not meet the Large space adjustment requirement needing width report to print at the limit switch limited separation of design amount of movement upper holder parallel motion, therefore, suitably tune up, corresponding for the spacing of limit switch desired level amount of movement to meet user demand herein.
The step of the fixed mount spiro rod length connecting parallel motion is lengthened according to desired level amount of movement.Equally, corresponding original equipment is designing Connection Bracket on amount of movement thus the Large space adjustment requirement driving the spiro rod length of its parallel motion deficiency to need width report to print, therefore, screw rod suitable for corresponding for length desired level amount of movement is replaced original screw rod herein, thus meet the demand of amount of movement.
What above-mentioned four steps mainly solved is all increases a difficult problem for the parallel motion amount of set square and set square place fixed mount.
Further, in order to meet whole printing to center requirement, also need to transform main paper carrying roll group.Concrete the main paper carrying roll group 3 of Gauss N75 comprises four paper carrying rolls as shown in Figure 1, and four paper carrying rolls divide on the set square 4 by the 7th paper carrying roll 31 and a set of set square mechanism of the 8th paper carrying roll 32 correspondence between two and arrange.During transformation, the paper carrying roll (i.e. the 8th paper carrying roll 32) arranged adjacent to two set squares 4 in main paper carrying roll group 3 is pulled down, then be divided into three sections, left, center, right, wherein left section is equipped with platen district with right section of side, and stage casing width is then relative with desired level amount of movement.
By the transformation of above-mentioned five steps, Whole Equipment is made to meet the demand of Large space adjustment from amount of movement, make winner's paper carrying roll become to may correspond to the adjustment of width different size simultaneously, thus solve originally cannot meet narrow report, problem that the printing of wide report requires center.
And in order to solve the problem of second the paper injection power loss mentioned in background technology, then also need to arrange belt pulley respectively on the axle of first one of them paper carrying roll of paper carrying roll group with on the axle of second one of them paper carrying roll of paper carrying roll group, and then be socketed above-mentioned two belt pulleys of interlock with a belt.Even if the first paper carrying roll group will be separated with final gear more than transmission gear in its gear case after 10mm gradually along with fixed mount amount of movement thus, continue motion under the power that one of them paper carrying roll of first paper carrying roll group also can be transmitted by one of them paper carrying roll of the second paper carrying roll group under the drive of belt pulley, just avoid the problem run out of steam.
Best, further a tightening device 7 can be set between the first paper carrying roll group, the second paper carrying roll group in this step, this tightening device 7 comprises pinch roller, depression bar, and wherein pinch roller connects depression bar and top is solid over pulleys carried and depression bar applies opposition with parallel motion.
By the transformation of above-mentioned steps, the folding machine solving original Gauss N75 cleverly designs guardian technique difficult point not enough due to amount of movement, cannot cannot be imprinted on narrow report to center and adynamia.Gauss N75 can be switched between the wide report of print or narrow report freely fast.
Just set forth through the adjustment flow process of the above-mentioned improved Gauss N75 type correspondence narrow report of printing and wide report below.
print wide report adjustment flow process, comprising:
Number of assembling steps, installs back on one jiao of corresponding two set squares 4 by the angle movable block 41 of cutting and separating; All be installed in main paper carrying roll group 3 on axle adjacent to three sections, the left, center, right of the paper carrying roll (i.e. the 8th paper carrying roll 32 in Fig. 1) of two cover set square organization establishes; The position of traction wheel in first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group is adjusted to corresponding with needing printing paper width.
To central step, according to the fixed mount for placing set square, the first paper carrying roll group, the second paper carrying roll group needing printing paper width levels to move Liang Tao set square mechanism, then the level attitude of adjustment set square, the first paper carrying roll group, the second paper carrying roll group and main paper carrying roll group being made it center and being on same straight line.
Equipment after adjustment as shown in Figure 1.
print narrow report adjustment flow process, comprising:
Partition step, takes off the angle movable block 41 of two set squares, 4 one jiaos of cutting and separating; Take off in main paper carrying roll group 3 adjacent to the stage casing of the paper carrying roll (i.e. the 8th paper carrying roll 32 in Fig. 1) of two cover set square organization establishes, and rear left section directly the section of keeping right be installed on axle; The position of traction wheel in first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group is adjusted to corresponding with needing printing paper width.

Further modification scheme:
Above-mentioned print narrow report adjustment flow process with print wide report to adjust in flow process all relate to the position of traction wheel in the first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group and be adjusted to the step corresponding with needing printing paper width.Because the first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group are all in the following equipment component inside of base station, therefore need whenever needs change printing fabric width all to the first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group in traction wheel on the paper carrying roll of each two adjust undoubtedly can at substantial man-hour, and the paper carrying roll often leaned against inside equipment is very difficult to adjustment.In order to improve this problem, preferably exist
transformation flow processin can by the first paper carrying roll group, in second paper carrying roll group and the 3rd paper carrying roll group, in two paper carrying rolls, the traction wheel correspondence of one of them is widened to and can covers on the narrowest paper of required printing, thus, due to the first paper carrying roll group, there is the traction wheel width of a paper carrying roll enough in second paper carrying roll group and the 3rd paper carrying roll group, need only to need the traction wheel adjusted on another paper carrying roll can guarantee to be pressed onto paper during the different fabric width paper of corresponding pressure, by the transformation of this paper injection sandblasting wheel, the adjustment that common minimizing eight is taken turns can be made, greatly save the efficiency of adjustment and convenient degree.
To sum up, by the modification scheme for the two spoke wheel favourable turn of Gauss N75 provided by the invention, overcome many restrictions of existing equipment, (as supported after transformation, 1562mm-1360mm sized paper prints demand can to support narrow larger newspaper printing demand of size difference further on the basis retaining original wide format newspaper printing, achieve the printing conversion of any wide cut newspaper between 781mm to 680mm), and modification scheme can keep equipment original appearance substantially, only need to carry out limited, local flow improvement and can realize object.
And with regard to improvement cost; contrast Koss Corp. provide to original Gauss N75 transform as can print width report quotation then up to more than 800 ten thousand yuan; and house of correction needs parts also to need to wait for that certain hour could be complete; in order to reforming equipment needs to shut down some skies; also need transformation side at least to send two people to assist, therefore its integrated cost is far above 8,000,000 yuan simultaneously.
The modification scheme of other journalism units known to contrast, its to the improvement expenses of single folding machine just up to more than 80,000 yuan, and improved paper size is only limitted to 1562mm and 1440mm two kinds, and the conversion of printing sheets specification once, needs two days time at least five people just can complete.
And this patent modification scheme to the overall recondition expense of two folding machines lower than 100,000 yuan, and equipment after repacking adds paper carrying roll adjustment in the folding machine printing sheets conversion electronic mobile set square mechanism that only need press a button, and only adjusts five paper injection sandblasting ring two people with an instrument and can complete for 20 minutes.And the maintenance cost dismounting of equipment can save time 90% than original design design after transformation, personnel ratios 4:1 saves artificial three people, and visible correctional effect is remarkable.
