Description

Lithographic press
The present invention relates to a kind of lithographic press with a print station.
Especially in the digital printing machine, high requirement has been proposed for the flatness of print station and the medium that will print.Why like this this is, is because for example must make this ink gun distance guiding with a constant about 1mm on the medium that will print when using ink gun.For known printing machine, in print station, be provided with negative pressure hole, avoid in medium to be printed, forming ripple so that make printed medium be drawn onto on the print station surface and therefore.
Should propose a kind of lithographic press by the present invention, wherein can guarantee to make the full surface of printed medium to be placed on the print station.
Designed a kind of lithographic press that a print station and are used to wait print the hold down gag of medium that has according to the present invention for this reason, wherein hold down gag has the guide rail that is parallel to and is arranged in the print station both sides, by this guide rail a rail that compresses that can move on print station is led.
Can make medium to be printed by means of compress rail pressure to print station and the air that may be present between medium to be printed and the print station surface is extruded when compressing waiting to print between medium and the print station when rail moves on print station by being provided with a kind of such hold down gag.Especially with a kind of medium to be printed is inhaled to pressing the method for brushing platform to combine so abutting on the print station with just can guaranteeing medium whole plane to be printed.
Compress in improvement project of the present invention that rail is provided with a brush or a roller is used for compressing printed medium.
No matter be or roller can make media implementation to be printed a kind of floating reliably by means of brush.The kind of medium to be printed, for example paper or film may be conclusive for selecting roller or brush.If a kind of roller is its roll-in and independent roller driving mechanism needn't be set passively so.
In improvement project of the present invention, can drop on the print station and and lift compressing rail from this print station by means of lowering or hoisting gear.
Can automatically floating medium to be printed by these measures, and guaranteed in addition: with respect to the appearance and size of print station, whole print station was smeared during less paper in printing.Lowering or hoisting gear for example has swing arm, and they are by means of the cylinder motion that hoists.
Print station is provided with the negative pressure hole of a plurality of feedings in the print station surface in improvement project of the present invention.
Such negative pressure hole for example can and pass print station perpendicular to print station.The negative pressure of connecting on negative pressure hole then is used for reliably medium to be printed being fixed at printing process.By means of just making that according to hold down gag of the present invention the presumable ripple of printed medium is floating.
In improvement project of the present invention, be provided with and can control the instrument that is used for negative pressure is connected negative pressure hole, therefore negative pressure is switched on the negative pressure hole within a time interval, in this time interval, compress rail by this negative pressure hole.
Make the floating much easier of medium to be printed in this way,, negative pressure is switched on the negative pressure hole because just when compressing rail and just passed through negative pressure hole.Have only after the compacted rail in corresponding position passes through and be floating, its result just makes medium to be printed inhale to the print station surface.Therefore be not to be enclosed in extruding of air between medium to be printed and the print station surface by having stoped the floating of the ripple that may occur in the medium to be printed by means of adhering to of negative pressure and having stoped simultaneously.As one man make by cooperatively interacting to compress the rail motion and to connect negative pressure, even when the thrust that compresses rail is comparatively speaking low, also guarantee so: might be present in ripple in the medium to be printed to compress rail just floating after moving on medium to be printed.
Negative pressure hole becomes to be parallel to the row that compress rail and is arranged on the print station in improvement project of the present invention, and wherein each connects negative pressure simultaneously by a row negative pressure hole or a position of being made up of a plurality of row that are merged into the position.
A kind of such mesh shape of negative pressure hole is arranged and is made its control easier.Compressing rail by after the row negative pressure hole, negative pressure still turns on this row negative pressure hole, even so that also can avoid medium to be printed to move on print station when rail continues motion when compressing.Even negative pressure also maintenance effect in printing process subsequently more aptly.
