The utility model overlaps the galley device in advance, comprise a horizontal table (1), puncher of workbench front (40) and two Building Y mark fine setting button (31) (32), the Building X mark fine setting button (33) of workbench side, and the navigation system on the workbench, this navigation system comprises the Building Y mark slide rail (11) (12) of the workbench left and right sides, respectively have slide (13) (14) and evil spirit's bar (15) (16) on two slide rails, and cover connection one Building X mark slide rail (21) between the mark slide of two Building Y, two slides (22) (23) and evil spirit's bar (24) (25) are gone up and be equipped with to this slide rail (21), and slide (22) (23) front end is set up the lens barrel (26) (27) that high power is amplified, the above is a basic building block of the present utility model, its characteristics are: between X-axis slide (22) (23) and lens barrel (26) (27) and table surface, the gap (about 40mm height) of possessing an appropriateness, galley (about 0.3mm) can freely be divided a word with a hyphen at the end of a line on work top, and the unlikely slide and lens barrel and influence of touching set proper coordinate, lens barrel (26) (27) is connected on the rule cross hairs generators (61) with lead in addition, be connected on the display (51) by output line again, galley cross line pattern (71) in the lens barrel form is amplified on display (51) fluorescent screen, (its multiplication factor can reach more than 70 times, far above ten times of general amplification lens barrels), and the display top is connected with a pair of rule cross hairs generator (61), this generator can produce one group on the display fluorescent screen can make the axially movable cross wire gauge of XY, workbench (1) front center place and offer the recess (10) of appropriateness in addition, being easy to pipette galley for the operator uses, and galley is pulled to the lower right, so that be close on the fine setting button (31) (32) (33).

When the utility model is worked, at first with fine setting button (31) (32) (33) zero setting on workbench (1) front side and right side; The fine setting button covers its inner stroke piece (311), the trip piece rear side with a cage (316) a screw with negative thread, in this screw, can screw in a place ahead that cooperates with it and have the screw rod (313) of screw thread, and this screw front end screw thread is distolateral a scrobicular ring, can detain with a dummy slider (314), this dummy slider (314) peaks in the cage, in the time of can making the tuning knob (315) when the rotary screw rear side, make screw rod not therefore and forward-reverse, therefore and only do rotation, and drive stroke piece (311) forward-reverse, and reach the purpose of adjustment; The inconvenience that the galley that causes in order to reduce the friction between stroke piece (311) and the galley moves, downside is established a recess in stroke piece the place ahead, and card is established a bearing in this recess, so that galley becomes a contact with contacting of stroke interblock, and minimizing frictional force therebetween, and the zero point of fine setting button is due to the upside centre of stroke piece, so that the fine setting button has the forward-reverse space of appropriateness, on the display fluorescent screen to rule cross hairs be back to the fluorescent screen central point, put into first galley again, and since galley when chromatography is made, just preestablish two cross line patterns (71) (72) thereon, all have two cross line patterns on every galley, and distance therebetween is certain, therefore after version to be printed is tiled on the workbench (1), just can be by the recess (10) of operator at table top front center place, come the mobile printing version with hand, make the front side of galley and right side by peaking at the end face of fine setting button, after mobile XY coordinate slide makes and is linked to that display (51) the galley cross line pattern (71) that fluorescent screen showed is rough and be positioned at fluorescent screen central authorities by Building X mark slide lens barrel (26) (27), promptly dial the evil spirit's bar on each slide of lock, make XY coordinate slide location, then adjust be positioned at the display top to rule cross hairs generator (61), make movably to the galley cross line pattern (71) that has amplified on rule cross hairs and the fluorescent screen identical after, (vertical to having on the rule cross hairs generator, and horizontal tuning knob, can be respectively in order to adjust XY graphed lines to the rule cross hairs), depress the punching unit (40) in workbench the place ahead, to the galley punching, (sizableness of alignment pin on the just big or small and printing machine version tube clamp bar in hole); And the punching unit pipettes conveniently for cooperating galley, and puncher oppositely is located at below, workbench front side, so that punching unit base is slightly above table top, inserts and extract replacing with what make things convenient for galley.

After first galley punching, must be by shrinkage pool place, workbench (1) front side (10), extracting galley then extracts out, because the space of an appropriateness is arranged between Building X mark slide and lens barrel and workbench desktop, influence so the extraction of galley and inserting can't touch slide and lens barrel and to set appropriate coordinate, thereafter, second galley is slipped into along desktop by workbench (1) front side successively, and come the mobile printing version with hand in the place ahead indent, make it to be posted by fine setting button end face, the galley cross line pattern (71) (as shown in Figure 3) that shown this moment on display (51) fluorescent screen, may proper suitable deviation be arranged with setting to the rule cross hairs, but all set owing to slide and to the rule cross hairs this moment, therefore the rule cross hairs is not overlapped in advance in the mode identical with printing cross hairs to adjust, but adjust galley with the fine setting button (31) (32) (33) of rotary table (1) side, the displacement up and down of mat galley, make the high power cross line pattern (71) that is manifested on display (51) fluorescent screen, approach set already rule cross hairs group is also coincide with it gradually in the mode of translation, after treating that the cross hairs group is coincide in twos, depress puncher again to the galley punching, take out galley then, then the 3rd, the 4th galley is just finished its pre-cover operation according to aforesaid way.

After punching, cross line pattern (71) (72) on every galley just is subjected between the central point of punching certain and identical distance is arranged with it, and the utility model is promptly as datum mark (center, hole of galley), the pre-cover operation of the pre-covering device of mat, make the punching center of every galley identical distance be arranged with cross line pattern (71) (72) on it, then, when version to be printed is inserted in the version tube of printing machine respectively, aim at the alignment pin of galley tube upper clamp bar with the punching of galley, is benchmark and make former with center, galley hole, even on the galley between cross line pattern (71) (72) distance be certain and identical setting, it is certain and identical becoming the accurate heart of clamp bar to distance between galley cross line pattern (71) (72), so after treating that four galleys are inserted the locking of version tube respectively, it is consistent that cross line pattern on its galley (71) (72) to the distance between the clamp bar alignment pin just reaches, the printed article that prints out with this, four cross line patterns of its left and right sides, just can overlapping unanimity, needn't allow printing machine many time of waste do adjustment work again, and reach the purpose of quick print, and printing registering device in the past, after galley is inserted printing machine version tube, because the pitch-row of four galleys is inconsistent to the distance between cross line pattern, it is right to do the accent that once connects once on printing machine by the technical staff, waste a lot of times and manpower, paper and printing ink, and bring considerable loss, rather unfortunate.

In sum, the utility model overlaps the galley device in advance, can be in advance identical datum mark be set in every printing, treat that its dislocation is gone into printing machine version tube after, just can produce consistent benchmark, do the adjustment operation and needn't lose time again, can therefore produce sizable time benefit, and reduce a lot of human costs, for being worth high four-color press, the economic benefit of its generation can't be estimated especially.
