In the first case, the doctor blade should define a closed area within which the design to be printed may lie, whereas in the second case two doctor blades may be provided either one of which may come into contact with the printing plate dependent upon the sense of rotation during the back-and-forth rotational movement. A cover for the ink tray is provided so as to minimise evaporation of ink components and to prevent contamination of the ink, the cover being closed except for a port through which the printing pad may pass to contact the printing plate. Ink within the tray may cover the printing plate so as to obviate the need for a distinct ink applying step.
Description
The present invention relates to a kind of method and apparatus, be used for carrying out inking and wiping such as the forme that uses on the pad printing machine that extensively is called tampon printing machine (Tampoprint).Specifically, the present invention is relevant with a kind of method and apparatus, wherein, printing-ink is added on set on the forme pattern, forme comes wiping by a suitable doctor blade, then by means of a tampon with printing-ink from the sucking-off of forme recess, this tampon is provided with as a member of printing machine.
In known tampon printing machine, one has on it forme of corrosion pattern or pattern generally to be mounted in the black groove, thereby a doctor blade is configured to many Yus printing ink on the forme surface is scraped off the recess of printing ink being left for forme.
Existing apparatus generally has two kinds of patterns.One China ink groove is that the members of fixing such as doctor blade then are configured to and can move horizontally on the forme surface.Members such as its another kind of pattern doctor blade are that the black groove of fixing then is to move horizontally below blade.These devices all need uncovered black groove, so the diluent of printing ink or other compositions will volatilize in a period of time.If so printing be carry out a period of time continuously just must suitably replenish printing ink, for example can replenish by means of an automatic interpolation diluent device.And thereby impurity can drop to pollution printing ink in the black groove at an easy rate.
Attempting to overcome aspect a uncovered black groove not enough, having one printing ink is contained in a suggestion in the jar of forme, and in that can be applied to printing ink the zone of forme, individual hole is being arranged.But this device still needs the very high forme of a kind of straight and even degree, therefore mainly is applicable to the forme with a less printing.
Known devices also has a problem to be in each presswork cycle the forme wiping and to add this two procedures of printing ink all be necessary, so this just very difficultly carries out continuous presswork with a fair speed.
European patent application EP-A-0012934 discloses a kind of method and apparatus of tampon printing machine indexing transfer ink material.Its forme is that cylinder pattern so cylinder both ends of the surface also are infected with printing ink, when changing plate cylinder, clean end face printing ink and very bother.And tampon can make pattern out of shape when the pattern transfer of plate cylinder surface sucking-off is to the flat stamping brushware.In addition, when tampon dropped on the forme, black groove lid all will be opened once, causes the volatilization of printing ink reducer.
A main purpose of the present invention is to reduce some problems that the method and apparatus of known inking and wiping on the tampon printing machine discussed above exists at least.
According to one aspect of the present invention a kind of inking of tampon printing machine and method of wiping of being applicable to proposed, printing ink can be added to one with this method is arranged on the pattern on the forme, forme is through wiping, then by means of a tampon that is provided with as member of printing machine printing ink from the sucking-off of forme recess, this method is characterised in that the cycling service of two procedures, first procedure is to relatively rotate the wiping that forme and doctor blade are implemented forme, second operation work then be with the printing machine tampon printing ink from the forme sucking-off, and doctor blade is to be in an inactive state.
Unidirectional rotation is always done in relatively rotating or can carry out step by step between forme and the doctor blade, and perhaps available a kind of mode is back and forth carried out.In both of these case, doctor blade can be maintained fixed forme then be rotate or forme can be maintained fixed doctor blade then be to rotate in a kind of mode back and forth.
An advantage of method of the present invention is that each print cycle can no longer need by using an inking device that can move separately to add inking.Implement this method with regard to an available fair speed like this.Forme can have the printing of continuous wiping more than in addition, thereby can make presswork to carry out at a high speed.
According to another aspect of the present invention, be that a tampon printing machine is provided a kind of inking and scrapes device for ink, this device comprises a black groove, a forme is housed in it, also dispose a doctor blade to wipe the printing ink of forme upper surface off, it is characterized in that being equipped with one and be suitable for the transmission device that between forme and doctor blade, produces relative rotation,, also be on black groove, to dispose a black groove and cover and make the volatilization of ink component be reduced to minimum level to finish the wiping of forme.
In this device, the part of the dress China ink of China ink groove almost keeps sealing fully, reserve opening on the cylindrical shape doctor blade anchor clamps that only pass black groove lid and install, be enough to make a printing tampon to descend printing ink is picked up on the pattern to be printed, thereby can prevent printing ink (such as diluent) volatilization to a great extent.In addition, impurity falls into the also greatly minimizing of possibility of printing ink.
For a kind of situation relatively rotate at this moment be progressively carry out and be on same direction, preferably doctor blade is made and to be limited an enclosure portion (such as a circular portion) and can be placed on a pattern to be printed on forme in this part, just carry out wiping in the time of below that pattern moves to blade.Another kind of situation relatively rotates in mode back and forth and carry out this moment, can dispose two doctor blades, dresses up and alternately contacts forme, and all these depend on the direction that relatively rotates between doctor blade and the forme.
