In order to adjust the circumferential speed of the printing cylinder to the unbalanced rotation of the impression cylinder, instantaneous rotary angle of the impression cylinder is measured from a zero angle line, preset rotary angle relationship between the printing cylinder and the printing cylinder is considered, the rotary angle of the printing cylinder is controlled through a cylinder drive motor from time according to measuring results.

Description

The control method of printing cylinder speed of printing machine
The present invention relates to a kind of control method and a kind of printing machine of printing cylinder speed of printing machine, mainly is flexographic presses.A plurality of printing cylinders of this printing machine all are equipped with the drive unit of oneself, and these printing cylinders are installed in a common impression cylinder next door, and impression cylinder also is driven.
Whether the printing quality of polychrome printing product depends primarily on the chromatography of all colours accurate, that is the position of the picture and text of each color is aimed at mutually.By DE-OS2941521,3437216 and 4308492 discloseder flexographic presses, there is an impression cylinder to obtain driving on these printing machines, also have a plurality of printing equipments, printing cylinder on these printing equipments is installed in the impression cylinder next door, and a centre wheel is housed, the driven wheel engagement of it and all printing cylinders on the impression cylinder.On this type of flexographic presses, if the diameter of the pitch of driven wheel and printing cylinder coincide, the peripheral speed of printing cylinder is identical with the speed that impression cylinder drives, and printing machine can guarantee that chromatography is accurate so.
The flexographic presses of new structure design is provided with a public impression cylinder for all printing cylinders, and impression cylinder and each printing cylinder all possess the driving of oneself.By its controllable type of drive, this type of printing machine allows the peripheral speed of printing cylinder and the peripheral speed of impression cylinder accurately to coincide, and whether the pitch that needn't pay close attention to driven wheel mates with the diameter of printing cylinder.
Equipped the printing machine of self-driven impression cylinder, the self-driven printing cylinder of its next door mounting strap, open by DE-OS3432572.
On this disclosed printing machine, equipped a self-driven impression cylinder, its next door is installed a plurality of with self-driven printing cylinder, the problem of its existence is: impression cylinder may be with unbalanced speed rotation, and the driving of printing cylinder can not coincide with this unbalanced rotating speed, produce overprint error thus, cause that the printed matter trace is fuzzy.Impression cylinder has big quality.Even impression cylinder more accurately moves around its mass centre (center of gravity) because of its quality, its center of gravity also needn't overlap with the geometric center of impression cylinder turning cylinder.Therefore, rotating the equilibrium that might not cause the impression cylinder shell around the equilibrium of mass centre rotates.Each driven wheel make and assembling aspect error also can cause the unbalanced rotation of impression cylinder, gear passes to impression cylinder with this unbalanced rotation.In addition, the bearing clearance can cause the appearance of the unbalanced and eccentric phenomena that the center impression cylinder drives.Particularly, eccentric if the big driven wheel of impression cylinder occurs, the unbalanced driving of impression cylinder can adjust.The off-centre of gear and foozle and/or other influence factors may cause: the driving that becomes the equilibrium of impression cylinder is rotated in the desirable equilibrium of CD-ROM drive motor, it is inhomogeneous to cause that subsequently banded printable fabric is carried, so that the chromatography mistake appears in banded printable fabric when printing by printing cylinder, its reason is the rotation that self-driven printing cylinder can't remedy the centre wheel lack of balance, because driving the rotating speed of printing cylinder and the driving rotating speed of impression cylinder coincide, the unbalanced rotation of impression cylinder by cause off-centre and/or bearing clearance can not be remedied under impression cylinder and the accurate situation of coincideing of cylinder speed of printing.
Thus, task of the present invention is: the method for explanation when proposing a kind of this paper and beginning, Using such method can be adjusted to the printing cylinder peripheral speed the unbalanced rotation of impression cylinder and come up, to avoid overprint error.According to this invention, can be from the zero degree line, measure the instantaneous corner of impression cylinder, consider the angle relation that presets between impression cylinder and the printing cylinder and, go up from the time by the drum driven motor rotation of printing cylinder is controlled according to the result who measures.
The present invention is based on following understanding, that is: the driving of impression cylinder can not be rotated according to the lack of balance peripheral speed and be controlled, because the moment of inertia of impression cylinder and accessory drives thereof is excessive, go to compensate the rotation of lack of balance by the control of this kind mode, be unapproachable.On the contrary, the quality that printing cylinder and drive unit thereof possessed is less, its moment of inertia can be controlled by certain way by controllable motor, the mode of its control is that the lack of balance rotation of printing cylinder peripheral speed and impression cylinder is matched, and so just can guarantee production chromatography printed matter accurately.
According to the present invention, the zero degree line---this zero degree line extends along the impression cylinder rotating shaft---from the imagination is measured the instantaneous corner of impression cylinder.For printing cylinder (space of a whole page cylinder) is controlled, with the instantaneous corner φ of impression cylinder GDZ(t) with the instantaneous angle φ that turns over of printing cylinder DZ(t) relatively, and it is adjusted to constant relatively rotating concerns φ DZ(t)=k φ GDZ(t) on.Wherein the implication of factor k is a constant rotation relation between impression cylinder and the space of a whole page cylinder, and this relation is corresponding with the radius or the diameter ratio of two kinds of cylinders.By this relation given in advance, can control according to given fixed relationship impression cylinder and the instantaneous peripheral speed of printing cylinder.
Angular speed v (t)=d φ/dt is provided by differential, and wherein φ (t) is instantaneous corner.According to the present invention, can give up differential, and only just can be sooner by the control angle and adjust to constant peripheral speed more accurately.Under the situation of the angular relationship k that considers impression cylinder and printing cylinder, if its instantaneous angle equates that then its peripheral speed also equates.
Implement a kind of printing machine of the inventive method, flexographic presses particularly, have a driven impression cylinder and a plurality of printing unit, printing cylinder on the impression cylinder next door all carries the drive unit that rotating speed can be controlled, according to the present invention, its unusual part is: on the circumference of impression cylinder, be provided with a plurality of marks with the spacing that equates.These marks are by a sensor scan, and sensor signal is sent to a control device---for example in the middle of microcomputer.The rotating speed of the drive unit of printing cylinder 7,8 is corresponding with the instantaneous corner of impression cylinder that obtains from sensor signal.The control mode of computer is: under the situation of considering angle relation between impression cylinder and the printing cylinder, make printing cylinder turn over corresponding angle in the identical time.
Sensor is made up of the reverberation electric transducer.
Mark line needn't be arranged on the impression cylinder circumference, it can be marked on the disc that impression cylinder rotates, and perhaps is marked on the annulus that impression cylinder rotates.
In addition, also can use pattern or the mark line that serves as a mark on impression cylinder, these marks can be gathered by sensor.
These mark lines can be arranged on the supporting body that drives impression cylinder, for example on disc.Wherein, for the state of arranging that makes mark line is correct, a calibration chart need be set, this table can be imported in the middle of the electronic memory and by microcomputer and read use.
To describe one embodiment of the present of invention in detail according to the schematic single diagram of flexographic presses below.
Illustrated impression cylinder 1 has the drive unit of oneself.Because there is foozle in driven wheel, so the slight off-centre of gear, the off-centre and the bearing clearance that particularly drive the gear wheel of impression cylinder can not be avoided fully, and it is unbalanced so also to have slight peripheral speed with regard to the driving that makes impression cylinder 1.This unbalanced phenomena can not be eliminated by the controlled driving to impression cylinder, because the moment of inertia of impression cylinder and drive unit thereof is bigger.
On the circumference of impression cylinder, be provided with 2, one sensors 3 of mark line by equidistant from distance, for example the reverberation electric transducer scans these mark lines.The signal of sensor 3 is delivered in the microcomputer, and computer very calculates the instantaneous corner of impression cylinder 1 exactly.Corresponding with the instantaneous corner of the impression cylinder that calculates, under the situation of considering angle relation between impression cylinder and the printing cylinder, computer 4 control CD- ROM drive motors 5,6, these two motors are used for driving the printing cylinder 7,8 on impression cylinder next door, make these two printing cylinders in time according to the angle relation corresponding angle that always lags behind, on contact wire, make the instantaneous peripheral speed of impression cylinder always corresponding with this with the instantaneous peripheral speed of printing cylinder.
Be that printing cylinder 7,8 has been installed anilox roll 9,10 in the usual way.
