Description
Technical field
Missed the present invention relates to the detection of cardboard cross-cutting machine cutter shaft kinematic error, more particularly to a kind of motion of spiral transverse cutting machine cutter shaft
Difference detection and compensation device and method.
Background technology
In corrugated board and honeycomb cardboard production process, transverse cutting unit is mainly used in cutting cardboard, and cardboard is cut into institute
The size needed, and spiral transverse cutting machine is small due to its required power of motor, production efficiency is high and is used widely.
As shown in figure 1, cardboard cross-cutting machine core is by motor 33, reductor 38, transmission system 34, cutter shaft 36, frame
39th, the part such as bearing 37 is constituted.Fig. 2 is rod knife structure chart, and rod knife blade 36-1 is arranged on cutter shaft rod.Cutting work part by
Two groups of cutter shafts are constituted up and down, wherein the hand of spiral of upper lower is inconsistent, upper cutter shaft is left-hand screw, and lower is right-hand screw.
During cutting work, by motor output power, after being regulated the speed by reductor, upper lower is driven to be transported by transmission system
It is dynamic, complete cut paper motion.In shear action, upper lower cutter is cut to the other end from one end of cardboard, until cardboard cut-out, because
This, during whole cut paper, the engagement effect of upper lower directly affects the quality after cardboard cutting, and upper lower is nibbled
Closing effect and the rotating speed of upper lower and the radial deformation and kinematic error of cutter shaft has direct relation.
In the prior art, the adjustment of cutting knife fully relies on the experience of workman, and cutting knife is determined by estimating or testing
Back lash.And the rotation synchronism of upper lower ensures mainly by gear drive, but two gears have in itself up and down
There is fit-up gap, meanwhile, abrasion can be produced after some time of use, and these will cause lower gear to be fully achieved together
Step.It is primarily present down with several aspect shortcomings：
(1) limited by the operation principle of spiral transverse cutting machine, when carrying out cutting work as far as possible, it is necessary to two cutter shafts above and below making
Complete Synchronization could complete to obtain preferable cut paper effect, but be due to that gear is present in transmission gap and long-term operation process
The abrasion of generation, will cause above and below two cutter shafts operationally produce nonsynchronous phenomenon, at this moment occur that cardboard can't cut, or
The problems such as person's cardboard otch is rough, influences the cardboard outward appearance and quality of production.
(2) after paper cutter is worn and torn using formation for a long time, it is impossible to transmit gap to gear by effective manner and carry out
Compensation, can only reach design requirement by more renewing gear so that the maintenance cost increase in later stage.
(3) in the prior art to upper lower kinematic error the problem of can not carry out quantitative measurement and analysis, can not
Adjusted in real time.
(4) control of the prior art to blade axis rotary speed belongs to opened loop control, it is impossible to which the effective speed discrepancy to cutter shaft is carried out
The control and adjustment of closed loop.
(5) cutter shaft can produce radial deformation and kinematic error in cut paper, and prior art can not measure the radial direction of cutter shaft
Deflection and kinematic error, while also position of the adjustment blade on cutter shaft without standard measure.

Radial deformation and kinematic error test, are mainly used in test cutter shaft (upper cutter shaft 3 and lower 16) and are carrying out cut paper
The radial deformation and kinematic error produced during work.The cutting that paperboard cutting machine completes to cardboard is mainly completed by cutter shaft,
When carrying out cardboard cutting, cardboard is needed to pass through in the middle of cutter shaft, and due to being extruded by cardboard, cutter shaft will necessarily be produced necessarily
Radial deformation and kinematic error, if can quantitative test to the radial deformation and kinematic error of cutter shaft, carrying out circular knife
Installation and adjustment when, the radial deformation and kinematic error of cutter shaft can be compensated, therefore, obtain cutter shaft and be moved through
Radial deformation and kinematic error in journey is very meaningful.
The laser pickoff on cutter shaft, when laser pickoff moves to the position that can receive light source, its laser
The position of luminous point will be changed, and pass through follow-up signal processing system, you can the radial deformation and motion for obtaining cutter shaft are missed
The position of difference.Because laser pickoff is arranged on the axial geometric center of cutter shaft, and positioned at the opposite side of circular knife, therefore can
To measure radial deformation and kinematic error amount of the cutter shaft when cardboard is cut, if radial deformation and kinematic error amount are located at institute
In the error range that can be received, then the adjustment of spiral cutter need not be carried out, if the radial deformation and kinematic error of cutter shaft surpass
Go out the scope of design, then the light spot position on laser pickoff will change, then now need to be adjusted cutter shaft,
To obtain more preferable cardboard cut quality.
Upper lower is as main cut paper moving component, and its rotating speed is had to as far as possible close to consistent, so can just be obtained
To preferable cut paper quality, and upper lower is due to rigging error, the presence of kinematic error equal error, will in motion process
Generation cumulative errors, and the kinematic error of the invention by twin shaft above and below measurement, and introduce error into the control system of system
Rectified a deviation, be adjusted finally by the movement velocity of the servomotor of the upper lower of amendment.

Laser pickoff above lower is then inputted without signal, if on during the cut paper lower generate it is nonsynchronous
Phenomenon, then the straight line of circular hole formation will be not exclusively vertical with the speculum of lower above and below upper cutter shaft light transmission device, if now
Second beam laser 22 is reached after speculum by light penetrating ring, it will cause the angled reflection of laser, and the laser now reflected will
It can not be returned along incident direction, and the laser pickoff above lower will receive signal, pass through light penetrating ring glazing
The position of source point can calculate delayed or advanced movement angle of the lower than upper cutter shaft, and now signal after treatment will
Central control system can be delivered to, central control system will be compensated to misalignment angle, that is, control the rotating speed of servomotor,
So that the rotating speed of upper lower levels off to unanimously, the speed discrepancy of lower can be so monitored in real time, while can be to knife
