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 newspaper remodeling method and can print width newspaper double width rotary press.
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 the thinking newspaper.Except the reduction newspaper layout, reducing the newspaper book size is also an important selection, reading except helping reader like this, more can save paper, wins larger economic benefit chromatography, also claims in the industry this way for " newspaper weight reducing ".
For this reason be born a kind of format specification of new-type newspaper, its printing area (type page), at the newspaper of the row of 32 centimetres of 24 centimetres of 38.5 cm x, 30 centimetres of 49.5 cm x, 31 centimetres of 48 cm x or 52 cm x, is commonly called as " narrow newspaper ".Narrow newspaper originates from the America and Europe, for convenient, at narrow or mobile space, read and design, and such as at train, while on bus, reading newspaper, after the old-fashioned space of a whole page launches, width is too wide, affects other people, the inconvenience reading.Can conveniently be folded into the shape of being convenient to reading after changing narrow newspaper into.Domestic appreciiable newspaper has also adopted this ratio (roughly meeting 1:0.615) as The Beijing News when correcting, city wall bulletin, Chongqing Times, Beijing Youth Daily etc.
And, except promoting applicable convenience, adopt in theory paper printing in a narrow margin, can save paper 5.2%-12.9%.As adopt 1360mm double width newsprint, and with the 1562mm newsprint, to compare, paper saving amplitude is: (1562-1360)/1562 * 100%=7.81%.If the year paper using amount of a newspaper office is 20,000 tons, can save 0.16 ten thousand ton of left and right printing market of paper using amount, cost is roughly equal to 7,200,000 yuan of Renminbi (by 4500 yuan/tons).
Therefore, from the energy-saving and cost-reducing environmental angle broad prospect of application of narrow newspaper in addition that reaches, in current journalism, narrow newspaper printing becomes a megatrend already.
On the other hand, printing equipment in using in the tradition journalism generally includes two kinds of single width rotary press, double width rotary presses, wherein the single width printing of rotary press is narrow gives the correct time, due to space of a whole page picture and text line of centers, with forme line of centers, paper line of centers and machine center line, overlap all the time (for example Fuji's starlight series), so only need adjust the demand that the subsidiary such as nippin rolIer, pressure roller can meet narrow newspaper printing.
And it is quite different for the double width rotary press, the folding machine part of equipment particularly, because two formes are equipped with in left and right on same cylinder, just make the line of centers of space of a whole page picture and text not overlap with the line of centers of the line of centers of forme, the line of centers of splitting paper and set square, once will change narrow newspaper printing, will go wrong.And more newspaper offices introduction in recent years is all the double width rotary press, purchasing new equipment needs new wholesale to drop into undoubtedly, and existing equipment often can only be discarded, how very waste, so will realize that narrow newspaper printing is to need in the industry one of problem of solution badly on existing double width rotary press.

1, can't meet printing requires center---and major cause is that two of folding machine overlaps adjustment stroke deficiency between set square mechanism levels, and be embodied in: two set square level intervals are too little, can't meet narrow newspaper printing demand; Only have ± the 10mm of design amount of movement of set square place fixed mount, can't meet the requirement of the above narrow newspaper printing amount of movement of 50mm.Moreover, in main paper carrying roll group respectively two paper carrying roll length corresponding with each set square fix, variable range is very little, once set square excessively mobile after, two paper carrying roll intervals for the center of cutting a sheet of paper just can't with the set square center-aligned, can't carry out presswork.Secondly, in main paper carrying roll group, the platen sector width of paper carrying roll is limited, after the set square over-deflection, can produce the problem that is difficult to good platen.
2, paper injection power is lost---mainly due to being fixed in the first paper carrying roll group on same fixed mount and the second paper carrying roll group the set square mechanism parallel motion time, also need to be with the fixed mount synchronizing moving, and then guarantee set square and the first paper carrying roll Zu Dui center requirement.And drive fixed mount after amount of movement surpasses 10mm, and drive transmission gear in the gear case of the first paper carrying roll group gradually to separate with final gear, and then run out of steam, making above-mentioned the first paper carrying roll group lose paper injection power can't work.
In addition, the paper carrying roll platen is not adaptive is also a problem, the position setting that is mainly reflected in traction wheel in the first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group arranged under corresponding each set square in original folding machine is only applicable to the 1562mm paper printing, there will be the problem of pressing less than paper during corresponding narrow newspaper printing.

The specific embodiment
By describing technology contents of the present invention, structural attitude in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
For the double width rotary press Gauss N75 in journalism that is common in mentioned in background technology, in order to adapt to wide, the narrow newspaper printing of different fabric widths, the invention provides a kind of Gauss N75 and can print width newspaper remodeling method, correspondence comprises reconstruction flow and printing adjustment flow process two parts.
Wherein, most crucial
reconstruction flowspecifically comprise:
According to the desired level amount of movement, by the part of adjacent one jiao of two set squares cutting, make this angle and set square be separated into independently the step of angle movable block 41 as shown in phantom in Figure 1.Can solve two set square relative displacemenies in original folding machine by this step transformation and surpass the problem that dieback can be touched mutually in design latter two set square corner of amount of movement 10mm and can't be close again.And the width of the angle movable block 41 under cutting and separating, the fabric width that prints according to actual needs narrow newspaper determines, as to when printing 1360mm double width newsprint, need to cut away the wide angle movable block 41 of about 50mm.
Widen according to the desired level amount of movement step of perforate that base station is placed with the fixed mount of set square.The perforate design amount of movement of fixed mount of placing set square due to former base station is limited, therefore in existing equipment, two set squares relatively will be near to before meeting narrow newspaper and printing, its fixed mount will can't be moved further because of the verge of opening of top to base station, therefore this step need to be widened perforate, the mode of widening can adopt widens perforate integral body, also can adopt the method that fixed mount movable part (diagram dotted portion) cuts off of only base station 100 can being blocked in the middle platform 102 between two set squares as shown in Figure 4.Thereby make fixed mount can meet the demand that needs the parallel motion amount.
Change the step of the limit switch spacing of corresponding fixed mount according to the desired level amount of movement.Corresponding original equipment is adjusted requirement in the limited satisfied large spacing of width newspaper printing that needs of the limit switch spacing of design amount of movement upper holder parallel motion, therefore, the corresponding desired level amount of movement of the spacing of limit switch is suitably tuned up, to meet user demand herein.
Lengthen the step of the spiro rod length of Connection Bracket parallel motion according to the desired level amount of movement.Equally, thereby corresponding original equipment Connection Bracket on the design amount of movement drives the spiro rod length deficiency of its parallel motion to need the large spacing of width newspaper printing to adjust requirement, therefore, the suitable screw rod of the corresponding desired level amount of movement of length is replaced to original screw rod herein, thereby meet the demand of amount of movement.
What above-mentioned four steps mainly solved is all the difficult problems that increase the parallel motion amount of set square and set square place fixed mount.
Further, in order to meet whole printing Dui center requirement, also need main paper carrying roll group is transformed.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 for by arranging on the set square 4 of the 7th paper carrying roll 31 and a set of set square of the 8th paper carrying roll 32 correspondence in twos mechanism.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 of left, center, right, its left section with right section side, to be equipped with ，Er stage casing, platen district width relative with the desired level amount of movement.
Transformation by above-mentioned five steps, make Whole Equipment meet from amount of movement the demand that large spacing is adjusted, make winner's paper carrying roll become can the adjustment of corresponding width different size simultaneously, thereby has solved the problem that the printing that originally can't meet narrow newspaper, wide newspaper requires center.
And in order to solve the problem of second paper injection power loss mentioning in background technology, also need to be on the axle of first one of them paper carrying roll of paper carrying roll group with the axle of second one of them paper carrying roll of paper carrying roll group on belt pulley is set respectively, and then with above-mentioned two belt pulleys of a belt socket interlock.Even the first paper carrying roll group is along with the fixed mount amount of movement will separate with final gear gradually over transmission gear in its gear case after 10mm thus, one of them paper carrying roll of the first paper carrying roll group also can be under the drive of belt pulley continues motion under the power that transmits of one of them paper carrying roll by the second paper carrying roll group, has just avoided the problem run out of steam.
Best, can further between the first paper carrying roll group, the second paper carrying roll group, a tightening device 7 be set in this step, this tightening device 7 comprises pinch roller, depression bar, wherein pinch roller connect depression bar and top solid on belt pulley and depression bar apply opposition with parallel motion.
By the transformation of above-mentioned steps, solved cleverly the folding machine design of original Gauss N75 upper because amount of movement is not enough, can't can't be imprinted on the guardian technique difficult point of narrow newspaper to center and adynamia.Make Gauss N75 to switch fast from printing between wide newspaper or narrow newspaper freely.
Below just through the adjustment flow process of the above-mentioned improved Gauss N75 type narrow newspaper of corresponding printing and wide newspaper, set forth.
print wide newspaper and adjust flow process, comprising:
Number of assembling steps, install back the angle movable block 41 of cutting and separating on a jiao of corresponding two set squares 4; By three sections of the left, center, right of the paper carrying roll (being the 8th paper carrying roll 32 in Fig. 1) that arranges adjacent to two cover set square mechanisms in main paper carrying roll group 3, all be installed on axle; 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 is adjusted to and needs the printing paper width corresponding.
To central step, according to need the printing paper width levels move two cover set square mechanisms for placing the fixed mount of set square, the first paper carrying roll group, the second paper carrying roll group, the level attitude that then will adjust set square, the first paper carrying roll group, the second paper carrying roll group and main paper carrying roll group makes it center on same straight line.
Equipment after adjustment as shown in Figure 1.
print narrow newspaper and adjust flow process, comprising:
The partition step, take off the angle movable block 41 of 4 one jiaos of cutting and separating of two set squares; The stage casing of the paper carrying roll (being the 8th paper carrying roll 32 in Fig. 1) that arranges adjacent to two cover set square mechanisms in main paper carrying roll group 3 is taken off, and the rear left section directly the section of keeping right be installed on axle; 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 is adjusted to and needs the printing paper width corresponding.
To central step, according to need the printing paper width levels move two cover set square mechanisms for placing the fixed mount of set square, the first paper carrying roll group, the second paper carrying roll group, take off the stage casing of the paper carrying roll arranged adjacent to two cover set square mechanisms in main paper carrying roll group, the level attitude that then will adjust set square, the first paper carrying roll group, the second paper carrying roll group and main paper carrying roll group makes it center on same straight line.
Equipment after adjustment as shown in Figure 2.
Further modification scheme:
In all having related to the first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group in the narrow newspaper of above-mentioned seal is adjusted flow process and printed wide newspaper adjustment flow process, the position of traction wheel is adjusted to the step corresponding with needing the printing paper width.Due to the first paper carrying roll group, the second paper carrying roll group and the 3rd paper carrying roll group all in the following equipment component of base station inside, therefore need to whenever needs change the 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 each paper carrying roll of two adjusted undoubtedly and can be expended a large amount of man-hours, and the paper carrying roll that often leans against the equipment inboard is very difficult to adjust.In order to improve this problem, preferably exist
transformation flow processin can be by the first paper carrying roll group, in the 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 be widened to and can cover on the narrowest paper of required printing, thus, due to the first paper carrying roll group, in the second paper carrying roll group and the 3rd paper carrying roll group, there is the traction wheel width of a paper carrying roll enough, need the corresponding traction wheel that only need to adjust while pressing different fabric width paper on another paper carrying roll can guarantee to be pressed onto paper, by this paper injection sandblast wheel transformation, can make the adjustment of eight wheels of common minimizing, efficiency and the convenient degree adjusted have greatly been saved.
To sum up, by the modification scheme for the two spoke wheel favourable turns of Gauss N75 provided by the invention, many restrictions of existing equipment have been overcome, can on the basis that retains original wide format newspaper printing, further support the newspaper printing of the face in a narrow margin demand that size difference is larger (as after transformation, supported 1562mm-1360mm specification paper printing demand, realized the printing of wide cut newspaper conversion arbitrarily between 781mm to 680mm), and modification scheme can keep the equipment original appearance substantially, only need to carry out limited, local flow improvement and can realize purpose.
And with regard to improvement cost; contrast Koss Corp. provide to original Gauss N75 transform as can print width newspaper quotation 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; for reforming equipment need to be shut down some days; also need transformation side at least to send two people to assist, so its integrated cost is far above 8,000,000 yuan simultaneously.
The modification scheme of other the journalism units known to contrast, its improvement expenses to single folding machine is just up to more than 80,000 yuan, and improved paper size only limits to two kinds of 1562mm and 1440mm, 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 whole recondition expense of two folding machines lower than 100,000 yuan, and the equipment after repacking is added the paper carrying roll adjustment in the folding machine printing sheets conversion electronic mobile set square mechanism that only need press a button, and only with five paper injection sandblast ring two people of an instrument adjustment, within 20 minutes, can complete.And after transformation, the maintenance cost dismounting of equipment can save time 90% than the original design design, and personnel ratios 4:1 saves artificial three people, visible correctional effect is remarkable.
Referring to Fig. 1-5, the present invention also provides a kind of width newspaper double width rotary press that prints, and it comprises folding machine, and described folding machine is mainly by wheel pressing shaft 1, and pinch roller 2, main paper carrying roll group 3 and the two cover set square mechanisms that are arranged side by side and base station 100 form.Wherein wheel pressing shaft 1 is topmost, be socketed with a plurality of pinch rollers 2 on it, main paper carrying roll group 3 is set in parallel in bottom, and it further comprises four paper carrying rolls, four paper carrying rolls are divided into the 7th paper carrying roll 31, the 8th paper carrying roll 32, and a set of set square of correspondence in twos mechanism arranges.Base station 100 is provided with the middle part of two cover set square mechanisms, can service platform for providing one.
