Description
Technical field
The invention belongs to the tune of the printing relative position during corrugated board making water-based printing, fluting and die cutting product
Section and holding relative position are constant, are related to corrugated paper plate printing machines tool technical field, more particularly to a kind of servomotor driving
Phase adjustment and on-line automatic compensation mechanism.
Background technology
Up to the present solution used in domestic and international cardboard box mechanical manufacturer is all：Use planet differential wheel
Architecture drives printing slotting die-cutting machine work, and what is be meshed with differential speed gears H gears is common AC gear motor.Normally
When work is without phase adjustment, host work, AC gear motor is in stop conditions；When needing into being exchanged during horizontal phasing control
H pinion rotations in reducing motor driving differential speed gears, thus can be adjusted to product by the relative position in printing process
The required position of design is got on, and realizes the design requirement of product.But in the manufacturing process of above product, due to Quality of Board
Reason, and machine construction cumulative errors influence to cause the error of the 2%-5% in print product, it is impossible to exchange the electricity that slows down with common
Machine is adjusted, and thereby results in 2%-5% percent defective, while bringing sizable difficulty to the examination and test of products.Due to conventional cartons
Mechanical/day of the daily output 100000 or more, so 2%-5% percent defective is 2000-5000 pieces/day corrugated board, converts into people
People's coin reaches 8000-20000 members/day, and year, the waste product proportion of goods damageds were in yuan/year of 2,400,000 yuan/year -600 ten thousand.
In corrugated case production process, the major factor of influence box paper product quality has：1 cardboard printing quality and printing
The chromatography degree of accuracy；The pattern and accuracy of 2 carton makings.Because above-mentioned reason causes many box paper products can not meet user
Packing instructions, thus select other species to pack, or the thus sales range and selling price of influence packaging product.
The content of the invention
The purpose of the present invention is that there is provided a kind of servomotor driving phase adjustment and on-line automatic benefit for existing issue
Repay mechanism.
The present invention is achieved by the following technical solutions：A kind of servomotor driving phase adjustment and on-line automatic compensation
Mechanism, including forme roller, forme roller are arranged in frame by bearing block, and end axle one end of the forme roller is reached outside frame
Differential gear train, the engagement power gear of gear one of differential gear train, the engagement servo motor tooth of gear three of differential gear train are connected behind side
Wheel, servomotor gear is socketed on the output shaft of servomotor, servomotor and installs encoder for servo motor, the servomotor
The man-machine interface of touch-screen is connected, the man-machine interface and servomotor of touch-screen connect control system, control system connection respectively
Absolute value encoder, absolute value encoder connection high speed camera, high speed camera aligns forme roller one end into paper side, described
Placed on the runout table for entering paper side of forme roller and zero-bit is provided with cardboard to be printed, the forme roller that the high speed camera is aligned
Detecting element.
As further improvement of these options, described forme roller is provided with printing plate.
As further improvement of these options, the differential gear train by gear one, gear two, gear three, gear four,
Countershaft, external gear, internal gear composition, the gear one are engaged with power gear, and gear one and gear two, gear three are coaxial successively
Integrally connected is actively set on an end axle of forme roller, while the end shaft end of the affixed forme roller of gear four, the gear three
Swing arm on activity set in countershaft, countershaft one end connection external gear, external gear meshing gear four, countershaft other end connection
Gear, internal gear meshing gear two.
As further improvement of these options, the external gear is identical with the number of teeth of internal gear.
As further improvement of these options, the gear two is identical with the number of teeth of gear four.
As further improvement of these options, the number of teeth of the gear two and gear four and external gear and internal gear
The number of teeth differs a tooth.

Into
As further improvement of these options, a kind of servomotor driving phase adjustment and on-line automatic compensation mechanism are first
Printed first with the principle of 2 frees degree of differential gear train, and by 1.5 kilowatts of 2000 revs/min of servomotor amendments and adjustment
During the error of zero produced by phase error；Because servomotor precision itself is far above common AC gear motor,
So now phase adjustment precision has been significantly greater than the phase adjustment precision of conventional products；Again because 1 tooth mistake difference is adjustable
Differential gear train transmission accuracy itself and adjustable mechanical structure further increase mechanical phase Adjustment precision.
As further improvement of these options, a kind of servomotor driving phase adjustment and on-line automatic compensation mechanism
The characteristics of be that error change of 6 kinds of colors with respect to zero-bit detecting element is detected by online high speed camera, by being produced
Carton 95-98% errors within ± 0.3mm scopes, meet both at home and abroad various fine work print requests, so this portioned product is not
Need servo compensation amendment；The 2-5% for being above ± 0.3mm of required amendment product；Therefore the servomotor in the application
And full servo machine can be ignored the cost and power consumption of servo-control system on year-on-year basis；The application is according to camera institute
The 2-5% measured discrete values size and the regularity of distribution, analyzes the overproof size of 10 cardboard error changes, and by watching
The servo programe and PLC control system taken in control system is modified to error, at the same servomotor, absolute value encoder,
Encoder for servo motor, and servo-control system and high speed camera constitute the servo drive system and servo of closed loop
Reponse system is corrected, 2-5% phase error is reduced to minimum, 6 color printing deviations, the relative position error value are effectively controlled
Less than ± 0.2mm, product quality is improved, the percent defective of product is reduced or essentially eliminate.
The present invention has advantages below compared with prior art：It is reasonable in design with compact conformation, phase error can be compensated,
The qualification rate of raising cardboard printing, rate of reducing the number of rejects and seconds, cost-effective input is that enterprise increases the benefit；It is poor by adjustable 1 tooth
Differential gear train structure, i.e. planetary gear construction, and using servomotor driving, high speed camera and aberration error analysis measurement are super
The product error law crossed beyond ± 0.3mm, then by servo-control system order-driven servomotor on error peak and low
Paddy region carries out servo amendment, and absolute value encoder connection encoder for servo motor and forme roller, so as to ensure that servo is driven
Dynamic time and the degree of accuracy of position.
