In another improvement project, air-blast device be targeted by wedge-shaped crevice, page peeled off from coating drum for auxiliary, described wedge-shaped crevice is collectively formed by conveyer device and coating drum.
Accompanying drawing explanation
Other improvement project is drawn by the following description of embodiment and affiliated accompanying drawing.
Unique diagram in accompanying drawing shows the coating apparatus ingredient as ink-jet printer.
Detailed description of the invention
Show ink-jet printer 15 the most partly.Show the coating apparatus of ink-jet printer 15, described coating apparatus to may be used for before page 1 is printed in this Local map to realize being applied in page 1 priming paint (primary coat) by means of the ink jet printing head not shown in figure.Here, described coating apparatus should go forward to be placed in described ink jet printing head at page conveying direction.Alternately, described coating apparatus may be used for realizing being applied in page 1 gloss varnish by means of described ink jet printing head after page 1 is printed.Here, described coating apparatus should be placed on described ink jet printing head on page conveying direction.
Described coating apparatus include one without fixture to pressure roller 2 and a coating drum 3, described coating drum together form printed slot 4 with described to pressure roller 2.Described coating drum 3 is by cylinder dressing 16 tensioning, for page 1 coating.Cylinder dressing 16 can relate to the blanket for going up gloss varnish all sidedly or relate to the flexible printing forme for locally going up gloss varnish.
When page 1 in wedge-shaped crevice 14 from printed slot 4 out time, the cylinder dressing 16 by coating fluid (printing-ink or printing gloss varnish) moistening makes page 1 adhere to or sticks on cylinder dressing 16.Wedge-shaped crevice 14 is so-called outlet wedge portion (Auslaufzwickel).The edge 20 not printed of page 1 extends over the leading section of the chamfered edge of cylinder dressing 16.The edge 20 that this does not prints is not provided with coating fluid, and, the edge 20 that therefore this does not prints is non-cohesive on coating drum 3.
Conveyer device 5 is constructed and arranged to stripping off device 6, for page 1 being peeled off from coating drum 3.Stripping off device 6 includes the suction belt 8 of circulation, and described suction belt 8 is turned round around slewing rollers 9, and one of these slewing rollers are illustrated.
Shown slewing rollers 9 have vacuum window 10, and described vacuum window extends in this slewing rollers 9 circumferential angle range less than 90 °.Vacuum window 10 rotates in terms of rotation and not with slewing rollers 9 jointly.Described slewing rollers can be configured to multi-hull type, wherein, rotates static roller segment and is provided with vacuum window 10, and, one or more roller segments of rotation carry suction belt 8.Such as, the roller core not rotating (static) can have vacuum window 10, and, the roller shell being provided with ventilation mouth can carry suction belt 8 and rotate around roller core, and described roller core carries roller shell.Vacuum window 10 constitutes aspirator 7, for page 1 is drawn into suction belt 8.Suction belt 8 is provided with perforation, makes page 1 be loaded the suction air from vacuum window 10 through described perforation.
The air blast beam 19 of this air-blast device is directed at wedge portion by air-blast device 13, and this air blast beam divides (aufklaffen) between the page being drawn in suction belt 8 and coating drum 3.Thus, air-blast device 13 facilitates as air scraper plate: page 1 is peeled off from coating drum 3 by stripping off device 6.
Conveyer device 5 further comprises vacuum chamber 18, and described vacuum chamber is arranged in shown slewing rollers 9 and figure between not illustrated slewing rollers.By being configured to the vacuum chamber 18 of suction box, the linear type section of suction belt 8 is made to be directed to.Make suction belt 8 be loaded suction air in the region of its linear type section by vacuum chamber 18, described in draw air across the perforation of suction belt 8 and be applied in page 1 and make this page therefore be fixed in suction belt 8.
When page 1 is paper (page thin, flexible) and when carrying along paper track 21, and conveyer device 5 works as stripping off device 6.This paper is maintained on coating drum 3 with tending to attachment.In order to make conveyer device 5 can work as stripping off device 6, this conveyer device 5 is adjusted to primary importance 11, is used for processing paper.In primary importance 11, in the stripping gap 23 formed together with coating drum 3 by conveyer device 5, the distance between suction belt 8 and the page being attached on coating drum 3 of conveyer device 5 is 0 to 10mm or preferably 0 to 0.5mm.In the direction of rotation of slewing rollers 9, vacuum window 10 is connected to peel off on gap 23.
For such print job: in described print job, page 1 is not by paper but by cardboard, then conveyer device 5 is adjusted to the second position 12 from primary importance 11 so that conveyer device 5 has bigger spacing relative to coating drum 3.In this print job, page 1 carries along cardboard track 22.Because cardboard (thick, hard page) is not inclined to being attached on coating drum 3, therefore conveyer device 5 works not as stripping off device 6 in the second position 12.In the second position 12, the minimum spacing between conveyer device 5 and coating drum 3 is more than 0.5mm and preferably greater than 10mm.Cardboard track 22 (described cardboard track is imaginary page delivery track equally as paper track 21) is the tangent line common with coating drum 3 to pressure roller 2.
At conveyer device 5 in the case of primary importance 11 is adjusted to the second position 12, shown slewing rollers 9 move on to or swing to position shown in broken lines together with suction belt 8 and vacuum chamber 18 from the position being shown in solid, wherein, in the case of oscillating motion, the point that swings of oscillating motion can be by the rotation axis formation of the geometry to pressure roller 2.In the second position 12, linear type section that guided by vacuum chamber 18, suction belt 8 is flushed with cardboard track 22.
One be such as configured to fixed guide plate, for the guider 17 that page 1 guides in cardboard pattern is arranged between printed slot 4 and conveyer device 5, wherein, the spigot surface of guider 17 flushes with cardboard track 22.
