Machine, it is only necessary to the function of smoothly transmission plate is completed, therefore using the relatively easy speed control mode of control mode.And preceding pinch
Pinch roller completes more accurate gap and eliminates function before roller motor driving, i.e., periodic quickly acceleration and deceleration process is then pressed from both sides
Pinch roller completes diaphragm plate and says good-bye function after sending roller motor to drive, due to the difference of motion mode and control accuracy, therefore it is forward and backward before
Roller motor is pinched by the way of the control of position.
The schematic diagram eliminated with reference to Fig. 2, plate gap.Preceding pinch roller drive system includes pinch roller driver 21, fore-clamp
Roller motor encoder 22, preceding pinch roller motor 23 and preceding pinch roller 24 are sent, wherein the preceding roller motor 23 that pinches is designed as servo motor.
Feeding section master control system 20 includes transmission translator encoder 25, transmission translator 26 and conveyer belt, wherein transmission translator 26
It is designed as frequency control motor.The quantity of pinch roller driver 21 is two, the two pinch roller drivers 21 are mutual by ECT
Connection, slave computer multi-axis motion controller 12 are connect by ECT buses with one of pinch roller driver 21, which drives
Dynamic device 21 is connect with transmission translator encoder 25 and transmission translator 26 respectively, and transmission translator encoder 25 is charged with transmission
Machine 26 connects, which drives the conveyer belt to rotate, and to realize conveying plate, transmission translator is compiled when work
Code device 25 feeds back the speed signal of transmission translator 26 to pinch roller driver 21.Another pinch roller driver 21 respectively with it is preceding
Pinch roller motor encoder 22 and the connection of preceding pinch roller motor 23, pinch roller 24 rotates before preceding pinch roller motor 23 drives, and realizes
Pinch plate, when work before pinch and pinch the position of roller motor 23 before roller motor encoder 22 is fed back to pinch roller driver 21 and believe
Number.Slave computer multi-axis motion controller 12 is also attached to laser range sensor 27, and the laser range sensor 27 is for measuring
Clearance checking signal is fed back to slave computer multi-axis motion controller 12 by the clearance distance between adjacent two pieces of plate material.
The schematic diagram that plate gap is eliminated gives between testing agency, core controller and final executing agency three
Relationship, wherein preceding pinch roller motor encoder 22, transmission translator encoder 25 and laser range sensor 27 be detection
Mechanism, laser range sensor 27 can provide standby signal when the head-tail of plate arrives at below laser, the standby signal
When reaching slave computer multi-axis motion controller 12, conveyer belt when slave computer multi-axis motion controller 12 acquires moment generation simultaneously
The position of encoder 25, in this way, prompting slave computer multi-axis motion controller 12 to acquire adjacent two pieces of plate material by laser sensor 27
Previous plate end moment and latter plate wrench moment conveyer belt encoder 25 position, respectively S1 and S2,
The gap delta S between adjacent two pieces of plate material can be calculated by S2-S1.
The gap can be divided into two portions by slave computer multi-axis motion controller 12 after the gap delta S between calculating plate
Divide and passes to preceding pinch roller to complete the action of gap elimination.Particularly, the process that gap delta S is eliminated is as follows：
δ S are split into two part δ S=δ S1+ δ S2, the wherein elimination of δ S1 can make preceding pinch roller 24 obtain one and add
Fast process allows its speed to be increased to the several times of line speed, and pinch roller 24 clamps plate and goes to chase after before which can be regarded as
Previous plate is caught up with, to eliminate portion gap δ S1；
After δ S1 are eliminated, slave computer multi-axis motion controller 12 can provide the elimination order of δ S2, i.e., so that fore-clamp is sent
Roller 24 obtains a moderating process, allows its speed to be eventually reduced to consistent with overlay film roller speed, realizes and overlay film roller speed sync.
It needs exist for proposing, the transmission speed of plate on a moving belt is greater than into the transmission speed after overlay film roller, this is
Because the quantitative plate that feeder is sent out within the unit interval can all be put away by collecting machine, exist between the plate on conveyer belt
Gap and enter after overlay film roller and join end to end between plate, therefore δ S2 also complete plate material and overlay film roller while being eliminated
The process of speed sync, with prevent due to plate enter after overlay film roller with overlay film roller speed it is inconsistent caused by " re-packing " phenomenon.
For slave computer multi-axis motion controller 12 when completing δ S1 and δ S2 eliminations, final executing agency is preceding pinch roller
24, provide a concept again here, i.e., before the speed of pinch roller 24 be dimeric：Basal rate+stack velocity.
Before plate does not enter into when pinch roller 24, there are one basal rate, the speed of the speed and preceding conveyer belt for 24 tools of preceding pinch roller
It is consistent, after plate enters preceding pinch roller 24, preceding pinch roller 24 starts gap elimination action immediately, obtains a superposition speed
Degree, the stack velocity are the additional velocities of generation during the acceleration and deceleration mentioned in first 2 points.
But the two additional velocities are not directly to be operated to preceding pinch roller 24, but by slave computer Multi-axis motion control
An imaginary axis is generated inside device 12, is gone to undertake stack velocity by imaginary axis, then the movement of imaginary axis is superimposed to preceding pinch
Roller 24, to realize acceleration and deceleration, this have the advantage that：The complexity for reducing movement code, due to what be detected every time
Gap is different, causes stack velocity to be not quite similar, avoids and assign different movement velocitys to preceding pinch roller 24 repeatedly, only need to use
Imaginary axis undertakes stack velocity, and the basal rate of preceding pinch roller 24 can remain unchanged.
With reference to Fig. 3, the T0 moment to T6 moment three opens plate (No. 1 plate, No. 2 plates and No. 3 plates) gap and eliminates beat
Period schematic diagram.Wherein, the lateral dimension of plate is 1100mm, every plate on a moving belt between be divided into ideal 200mm,
After the gap elimination action of preceding pinch roller 24, the gap between plate shorten to 1mm, thus within the feeder unit interval
The transmission speed of feeding unanimous circumstances lower conveyor belt can be set as 1100+200=1300mm/s, into overlay film roller after pinch
Feeding transmission speed is 1100+1=1101mm/s.Before 200mm starts after detecting the wrench of every piece of plate pinch roller 24 into
Row pinches, i.e. acceleration and deceleration process.
By the oblique line portion at T1 moment as it can be seen that No. 1 plate has the stroke of 500mm long during acceleration and deceleration by preceding pinch roller
24 " eating up ", i.e., in the stroke of this 500mm, No. 1 plate is also superimposed other than having original basal rate 1300mm/s
Speed causes the gap between No. 1 plate and No. 2 plates to become larger instead to complete the process of pursuit.The moment from T2 to T3 as it can be seen that
Since No. 1 plate has been completed to pinch, speed is reduced to 1101mm/s from 1300mm/s, and No. 2 plate speed and conveyer belt
Speed unanimously remains 1300mm/s, therefore the gap between 1, No. 2 plate gradually reduces again, the moment from T2 to T3,1, No. 2 plate
Between gap be reduced to 280.8mm from 440mm.From T3 to T4 during the moment, since No. 2 plates are with average speed of advancing
Acceleration and deceleration process more than 1101mm/s pursues No. 1 plate, terminates pinch process in No. 2 plates of T4 moment, No. 1 plate of pursuit is straight
It shorten to 1mm to the gap between two pieces of plate material.T0 to the T4 moment is the complete mistake for giving every plate and carrying out gap elimination
Journey, subsequent every plate repeat above-mentioned gap and eliminate process.
In practical work process, since the gap between every plank is not the 200mm of standard, the speed of conveyer belt
Also the 1300mm/s given by not being, but the measurement in gap can be given slave computer multiaxial motion control by laser range sensor
Device processed is realizing head and the tail phase to be finally reached every piece of plate so as to adjust the length of T0 to T4 each periods after overlay film roller
Purpose even.
To sum up, control system is eliminated in plate gap of the invention, is encoded using laser range sensor and conveyer belt
Device realizes the measurement of the clearance distance between adjacent two plates, while laser range sensor also completes what prompt wrench reached
Task；Gap segmentation calculating is completed using slave computer multi-axis motion controller, two-part gap is eliminated and virtual axle speed is folded
Add function；The driving of conveyer belt is controlled using the frequency control motor under speed control mode, the driving of preceding pinch roller using position
Servo motor under molding formula effectively reduces control difficulty, increases control accuracy and reasonably saves hardware costs
(belt-driven need not use servo motor to drive).Therefore, plate gap of the invention eliminates control system and utilizes servo control
The electrical technology of system realizes that adjacent two plate is end to end, and the gap realized between adjacent two plate is eliminated, and film is not wasted
Material accomplishes that the utilization rate of film is more than 95%, is said from economy point, saved membrane material, it is more to save excision slab edge
The work of remaining membrane material reduces production cost, and compared with prior art, design difficulty is small, it is easier to realize.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
