The specific embodiment
Fig. 1 represents an offset press, the first printing equipment cylinder that it has first printing element 6 to the 10 and second printing equipment cylinder to 20.Material band 5 moves between the printing equipment cylinder is to 10 and 20 and passes and by printed on both sides.The first printing equipment cylinder comprises first plate cylinder 12 and first blanket cylinder (Gummituchzylinder) 14 to 10.On first plate cylinder 12, preferably be provided be fixed on first plate cylinder 12 extend axially at interval in flat hectograph printing forme.But but also can be other structure, the plate cylinder of digital imaging for example.The rubberized fabric of the form of sleeve that can axially load onto and take off preferably is set on first blanket cylinder 14.The second printing equipment cylinder comprises second plate cylinder 22 and second blanket cylinder 24 in a similar fashion to 20.Second plate cylinder 22 and first plate cylinder 12 irrespectively are driven.
Fig. 2 represents along the cutaway view of A-A of cutting line shown in Fig. 1 and B-B, wherein owing to only express the rider roller of the inking device and dampening device for simplicity.First plate cylinder 12 and first blanket cylinder 14 can be driven by first motor 31 and first transmission device 33, and second plate cylinder 22, second transmission device 34 and second blanket cylinder 24 can be driven by second an independent motor 32.In this way, plate cylinder 12,22 motor 31,32 by separately irrespectively for example is conditioned in a circumferential direction each other and is used for carrying out circumference the version location is regulated.Also can imagine the replacement form of implementation of two electric motor structures that substitute the disclosure, wherein first plate cylinder 12 can irrespectively be regulated with second plate cylinder 22, for example a kind of three-motor structure, wherein first plate cylinder 12 is by first Motor Drive, two blanket cylinders 14,24 are driven by three-motor by second Motor Drive and second plate cylinder 22.And the monomotor structure also is possible, in the case, for example can use the helical teeth transmission device to change the phase place of plate cylinder 12 and 22.
As shown in Figure 1, printing machine 1 comprises that a configuration gives first inking device 40 of first plate cylinder 12 and first dampening device 60 that first plate cylinder 12 is given in configuration, and second inking device 50 of second plate cylinder 22 and second dampening device 70 that second plate cylinder 22 is given in configuration are given in configuration.The inking device 40 and 50 is directed to China ink on the corresponding plate cylinder 12,22 from print cartridge, and dampening device 60,70 is transported to wetting agent on the corresponding plate cylinder 12,22.When hectographic printing, formed image is transferred on each corresponding blanket cylinder 14,24 and is then printed to respectively on the face of material band 5 on the printing forme that is supported by plate cylinder 12,22.
First inking device 40 comprises first rider roller 42 and second rider roller 44, and when plate cylinder 12 rotated, they turned and are displaced sideways.First inking device 40 is driven by first motor 31, and first plate cylinder 12 is connected with rider roller 42,44 by first transmission device 33 thus.Rider roller 42,44 is coupling by this way for example, and promptly they are gone up in side direction (axially) and move 0.154 times oscillating quantity when first plate cylinder 12 turns around.The complete side direction that oscillating quantity is defined as rider roller moves back and forth.The distance that wobble length is defined as moving from the zero position to the maximum.An oscillating quantity also means 360 ° motion in a circumferential direction.In the example that provides, when first plate cylinder 12 changeed 6.5 circles, rider roller 42,44 carried out complete side direction or sideshake and gets back to the home position.During first plate cylinder 12 turned around, first rider roller 42 preferably usually being displaced sideways an amount ND, wherein 360 can not obtain integer divided by ND.Phase angle between first rider roller 42 and second rider roller 52 can reach unlimited number in this way.But when 360 obtained integer divided by ND, this integer was more preferably greater than 2.
First inking device 40 comprises other inking device roller, and they are not displaced sideways and only rotate.The sideshake of the first and the 3rd rider roller 42,44 helps forming a China ink layer uniformly on plate cylinder 12.
Second inking device 50 and second dampening device 70 of second plate cylinder 22 also comprise each rider roller 52,54 or 72.These rider rollers 52,54 and 72 are by second drive motor 32 couplings of transmission device 34 with plate cylinder 22. Roller 52,54 and 72 is 120 ° of phase shiftings each other preferably.
180 ° of preferably relative first rider roller of second rider roller 52 42 phase shiftings are so that 180 ° of 180 ° of the 4th rider roller 54 relative the 3rd rider roller 44 phase shiftings and the first wetting agent rider roller, the 62 relative second wetting agent rider roller, 72 phase shiftings.Because second rider roller 52 and first rider roller 42, the 4th rider roller 54 and the 3rd rider roller 44 and the second wetting agent rider roller 72 and the first wetting agent rider roller 62 are positioned on each similar height, so this anti-phase layout reduces vibration according to Mathematical Modeling or even eliminates.Roller 52,54,72 opposed rollers 42,44,62 move in the opposite direction.
Sensor 142,144 can be set, 152,162 and 172, they detect respective rollers 42,44,52,54,62,72 lateral position.These sensors preferably constitute the proximity sensor, for example preferably make magnetic proximity sensor, and they can detect rider roller allocation really, and as the peak excursion of rider roller, wherein this position can be used as the reference position.When rider roller 52,54 and 72 when coupled to each other, single-sensor 172 can be set be used for second inking device 50 and second dampening device 70.When rider roller 42,44 and 62 when coupled to each other, single-sensor just is enough to the lateral position of measuring roll 42,44 and 62.
Be located at incremental encoder 82 and 182 on plate cylinder 12 and 22 and can respectively be used for determining the revolution of each plate cylinder 12 and 22. Encoder 82 and 182 step-by-step countings that produce during high-speed counter 81,181 respectively continues to rotate to plate cylinder continuously, wherein the preferably every cylinder circle of encoder produces 1000 signals.In addition, the exact position of plate cylinder can be determined, and just can determine the accurate lateral position of rider roller thus, because plate cylinder and rider roller are coupled on driving, and the reference position of rider roller, for example its peak excursion can be determined by the sensor.
Fig. 3 represents the flow chart of a method for optimizing of the present invention.
At first in method step 401, with a fixing processing speed, as 15 meters driving printing machines of per minute 10 commentaries on classics, and the conventional print speed printing speed continuously of the relative printing machine of this speed is lowered during following method step.
Print in second method step 402 and be interrupted, in other words, blanket cylinder and material band to be processed are thrown off.Plate cylinder also can be thrown off with blanket cylinder simultaneously.This disengagement of cylinder can relate to printing element 6 and 7 at least, typically, in turn is provided with four such printing elements at least up and down in a printing equipment tower.Transmitting for the continuation of material band to have a printing element to remain on printing state at least, promptly the blanket cylinder of this printing element do not throw off with the material band and thus this material band can continue to drive by printing machine.
In next method step 403, controller 80 sent signal (see figure 2)s and make be in not that the plate cylinder of contact condition enters a circumference to the version position, in this position, obtain the calibrating position of a required circumference at last, promptly on this position, can produce required printing quality the version location.The printing forme that participates in the plate cylinder of printing is thus regulated the version location regularly according to circumference.
In next method step 404, for example form the lateral position that the rider roller that is connected is determined these rider rollers with the plate cylinder of throwing off for each.Carve at this moment because the laterally offset of rider roller reaches its corresponding reference position, as peak excursion, corresponding high- speed counter 82 and 182 resets to null value.The corresponding plate cylinder 12 or 22 the value that makes counter that whenever turns around subsequently increase a unit.
Can regularly carve really by the clock transmitter is predetermined at one, relevant printing cylinder, " be freezed ", promptly for example be read out and intermediate storage also can offer other method step as the Counter Value of an opposed plate cylinder of printing element.Rider roller, can determine according to this Counter Value as the exact position of the phase place of roller 62 and 72.
After having detected for example laterally offset of opposed rider roller, will in next method step 405, determine and the best adjusting of execution.For example plate cylinder 12 or 22 can determine to rotate 360 ° on the direction thus, because this causes: form the rider roller be connected, can closely be caused a state as rider roller 62 or 72 with plate cylinder, mode is to be moved to 180 ° of phase shiftings, and does not influence the calibrating position of circumference to the version location.If opposed rider roller 62 and 72 leaves two circles of required phase difference greater than the plate cylinder of correspondence, then can make plate cylinder 12 (for example forward) and (backward) rotation in the opposite direction of another plate cylinder 22 on a definite direction.
But also can, when the required away from each other phase difference of opposed rider roller during, do not consider this adjusting less than a circle of the plate cylinder of correspondence.And when one or the multi-turn that will carry out plate cylinder are regulated, just be necessary to carry out phase adjusted because deviation when only being a circle of plate cylinder by rider roller only cause very little interference, as the interference of swing form and can save the required adjusting time thus.
In case after the adjusting of one or more printing elements of disengaged condition carried out, they can get back to contact condition, promptly to the state of material band printing.Other the printing element that at this time of day is not conditioned, for example, the continuation of material band then may be directed to disengaged condition and operation method step 401 now to 405 for transmitting printing element on contact position.
According to the structure and the position of printing machine, such as rider roller 42,44,52,54,62,72 height, the rider roller 42 of the desirable printing equipment 10 of winning, required phase shift between the rider roller 52,54 and 72 of 44 and 62 and second printing equipment 20, this will make the vibration of printing machine reduce.Should determine and to realize by mathematical computations or test result.Rider roller 42 when for example first printing equipment 10, the rider roller 52 of 44 and 62 and second printing equipment 20,54 and 72 when having similar position, similar quality and similar wobble length, the phase shift of then estimating roller causes vibration minimum when being 180 °, because roller 42 is on the direction opposite with roller 52, roller 44 on the direction opposite with roller 54 and roller 62 on the direction opposite, move with roller 72.When roller is in differing heights, also can use Mathematical Modeling to determine the required phase shift of roller 42 and 52.24 moment M that rider roller produced for 8 grades of printing equipment towers can calculate as follows: M is formula w
2* s
i* d
i* m
i* sin (w*t+f
i) i=1 to 24 and, wherein w is the frequency of rider roller, f
iBe the phase place of the relative reference value of rider roller i, m
iBe the quality of rider roller i, d
iBe the center of gravity of rider roller i to the edge distance and the s of (Boden)
iIt is the amplitude of rider roller swing.Because the phase place f of the rider roller of the rider roller group of a definite plate cylinder
iThe difference that forms the phase place of a relation and the phase place of a rider roller group and second rider roller group each other is a constant coefficient df, so can determine the phase shift df an of the best, the moment minimum that produces when this phase shift.
Another way is, can use accelerograph, be preferably the zero frequency accelerograph, so that the vibration actual value that produces in printing machine 1 obtains according to the phase place in-migration of roller 42 and 52.For measuring vibrations can be provided with a vibrating sensor 300 on the framework 301 of printing machine 1.Can in printing machine 1, determine in this way and the corresponding minimum vibration of required phase shift.
As representing among Fig. 2 that printing machine 1 also comprises a controller 80, its receiving sensor 142,144,152,154,162,172 and input and control printing machine drive unit and motor 31 and 32 of counter 81 and 181.This controller 80 can comprise a processor or a plurality of processor, for example Intel-Pentium (Intel Pentium) processor and new range thereof.First motor 31 drives first plate cylinder 12.Therefore controller 80 can cause the adjusting of the circumference of first plate cylinder to the version location by motor 31.The circumference of second plate cylinder 22 will be realized by motor 32 and controller 80 adjusting of version location.In order to change the phase shift between roller 42 and 52, plate cylinder 21 or 22 rotates on clockwise or counterclockwise direction not changing under the situation of its circumference to the version location, for example, turns over 360 ° on a whole circle shown in Fig. 3 method step 405.
For example rotatable 360 ° of first plate cylinders 12.According to the relation between the rotation of the wobble length of roller 42 and plate cylinder 12, roller 42 (and roller 44 and 62) is to being displaced sideways certain distance, and for example 0.154 of a wobble length.Whenever the turn around phase place that causes roller 42 opposed rollers 52 of first plate cylinder 12 is displaced sideways 55.44 ° at a phase angle (wobble length=360 °, i.e. 0.154 wobble length=55.44 °) when second plate cylinder 22 stops.Controller 80 makes cylinder 12 rotate multi-turn before the printing beginning, and cylinder 22 stops, so that reach required phase shift between roller 42 and 52.
According to the form of implementation of a modification of the present invention, can on the framework of printing machine 1, be provided as the vibrating sensor 300 that accelerograph constitutes at least.Printing machine 1 is devoted oneself to work and is measured the vibration degree of printing machine or frame parts.If vibration surpasses a required threshold value, then change the phase place of roller 24 and 52, so that reach minimum vibration or make vibration less than a definite threshold value.Then can begin the production run of printing machine.
Title used herein " plate cylinder " comprises all types of visual cylinders, but below for example also comprise the cylinder of the digital imaging of no forme.
Required phase shift can be an approximation that makes printing machine be lower than the maximum functional swing.Therefore required phase shift for example can be arranged in error margin be 6 ° with an interior value.
Being displaced sideways in Fig. 2 of roller 42,44,52,62,72 that moves back and forth for clarity sake represented large.
In Fig. 1, only understand a printing equipment in detail, but can know by accompanying drawing and to see, on first printing equipment, can be provided with another printing equipment.Though can save the position of machine by this structure, because the height of printing equipment increases the dither effect of rider roller.Therefore the present invention is particularly suitable for the printing machine that printing equipment is arranged up and down.
Especially in the case also can be, swing the method according to this invention of the printing equipment tower that is caused by the rider roller of the printing equipment of arranging is up and down reduced or is eliminated, wherein a mathematical computations that is used for reducing or eliminates a required phase angle of vibration, will consider rider roller the to be considered layout on the differing heights on the base plate in the printing equipment tower.
