Description
Technical field
The utility model with print after thermoprint automatically, cross cutting relevant, belong to a kind of paper navigation system, particularly a kind of printed matter paper vision positioning system for the automatic hot stamping die cutting machine of sheet-fed.
Background technology
Automatic hot stamping die cutting machine, as shown in Figure 1, comprise feed unit 1, defeated paper unit 2, main computer unit 3, stripping unit 4 and delivery unit 5, due to when printing sheet-fed offset press be that edge by paper positions, therefore after printing, carry out thermoprint and cross cutting adds man-hour, also need to position by paper edge, to guarantee printed patterns and the relative positional accuracy that prints rear hot stamping pattern or cross cutting, impression.Concrete positioning principle is: while utilizing sheet-fed offset press to print, paper is by the delivery platform input printing element of the defeated paper of offset press portion cover, front lay on delivery platform and side mark carry out longitudinally (Y-direction) and the laterally location of (directions X) to paper, make word, the pattern of printing take paper edge as position reference.
At thermoprint, cross cutting, add man-hour, as shown in Figure 2, the defeated paper platform 11 of processed printed matter 10 logical feed units 1 is delivered to paper position location to paper sheet positioning mechanism, first printed matter 10 is carried out to front predetermined bits, then by drawing rule to carry out side mark location to printed matter 10.In direction of feed, the front end of defeated paper platform 11 is provided with rocker 9, and the front end of rocker 9 is equipped with tooth row 7, and front lay 8 is located between rocker 9 and tooth row 7, draws rule 6 to be positioned at the fore side of defeated paper platform 11.Draw rule 6 to comprise pinch roller 61, roller 62, cam 63, connecting rod 65 and fixed head 66, connecting rod 65 is arranged on fixed head 66 and can be rotated around this fixed axis by a fixed axis, connecting rod roller 64 is equipped with in one end of connecting rod 65, the other end is equipped with rotating pinch roller 61, cam 63 is arranged on fixed head 66, roller 62 coordinates with pinch roller 61, and this roller 62 is arranged on fixed head 66 and by the driving mechanisms control of main computer unit 3.When printed matter 10 arrives the position of front lay 8, as shown in Figure 2 and Figure 3, draw the pinch roller 61 of rule 6 in lifting status (shown in dotted line), when printed matter 10 completes behind location at front lay 8 places, at cam 63(, by the drive unit of main computer unit, controlled) driving under, draw rule 6 pinch roller 61 to press down with printed matter 10 and contact, the below of printed matter 10 is roller 62, and its rotation makes printed matter 10 carry out lateral register to direction (directions X) movement of side mark 12.Under the clamping of pinch roller 61 and roller 62, printed matter 10 near side mark 12 until contact with side mark 12, due to the rigidity of printed matter 10 and stopping of 12 pairs of printed matters 10 of side mark, between pinch roller 61 and roller 62 and printed matter 10 paper, skid, thereby guaranteed the location of paper in side direction.Printed matter 10 completes behind location, and connecting rod 65 rotates pinch roller 61 is lifted, and printed matter 10 is decontroled, and paper-transferring gripper 7 is held printed matter 10 in the month and pulled into and in main computer unit 3, carry out thermoprint or cross cutting, impression processing.Because printing plate or cross cutting, impression cutter version relative position are fixed, thus the relative positional accuracy of thermoprint after having guaranteed printed patterns and having printed, cross cutting processing.
Said structure for be common printed machine and hot stamping die cutting machine, and current digital printing apparatus adopts, not take paper edge and carry out lateral register as positioning datum, after seal, thermoprint and cross cutting add man-hour, with printed matter paper edge, do not locate yet, but take printed matter picture and text or position as post-press finishing needs the positioning datum printing product paper that is labeled as of special printing, to guarantee the relative positional accuracy of hot stamping pattern or cross cutting, Indentation position and printing figure message.Thermoprint after the paper to 80 grams/m prints, cross cutting add man-hour, and because the rigidity of paper is smaller, when printed matter paper comes on the locating piece of side mark under the clamping of pinch roller and roller, paper edge is easily out of shape, and causes the error of lateral register.
