Moving knife knife face breadth is total breadth A, therefore, need to only utilize from moving knife X-axis micromatic setting and enable from moving knife Y-axis roll-setting gear
The accurate positioning of total breadth A can be met to it from moving knife and driving knife to knife.And the driving knife knife face position of the first carving knife group
Setting can also be obtained relative to the X-axis displacement L1 ' of X-axis zero point by design, installation or actual measurement.Therefore, the present embodiment can omit
The slave moving knife knife face displacement sensor and cutter workbench displacement sensor of first carving knife group and quadrisection knife group.
Based on above-mentioned apparatus, the X-axis displacement of targets X of the 2nd component cutter group2, the 3rd component cutter group X-axis displacement of targets
X3And the 3rd target breadth A3Calculation formula it is as follows:
X2=A1+L1’-(S2+D2) (example 4-1)
X3=(A2+S2+D2+X2)-(S3+D3) (example 4-2)
A3=A-A2-A1(example 4-3).
In formula, L1’、A、D2、D3For fixed value, A1、A2For setting value, S2、S3By from moving knife knife face displacement sensor
It obtains.
The operation principle of the present invention is that:
It is enabled by openable and closable attachment device from moving knife assembly and driving knife assembly sync bit referring to Fig. 2, Fig. 3
It moves, while X-axis of the precise measurement from moving knife knife face relative to laser sensor measurement point is displaced Si, grating reading head measurement point phase
For the X-axis actual displacement X of grating scale zero pointi' and X-axis of the grating reading head measurement point relative to laser sensor measurement point
Width DiFor known fixed value, it is based on above-mentioned parameter, user inputs target breadth Ai, the X-axis of cutter workbench can be calculated
Displacement of targets Xi。
Due to establishing rigid connection from moving knife assembly and driving knife assembly, so that from moving knife knife face and driving knife knife
The shift value that face occurs is identical, need to only enable aligning from moving knife knife face and driving knife knife face at this time, can utility Si、Xi’、
Di、AiThe X-axis displacement of targets X of calculated cutter workbenchi, thus enable driving knife and reach predetermined work position from moving knife, benefit
With the wide cut between each component cutter group, cutting obtains the paper of target breadth.
After each component cutter group reaches predetermined work position, openable and closable attachment device separation reserves for cutting paper
Working space.
It when cutting paper, is stretched out from moving knife feeding gas cylinder rod, reaches operating position from moving knife.Then starting driving knife electricity
Machine, driving knife start to rotate.Order is passed through by cutting paper between moving knife and driving knife, using driving knife with from the rotation of moving knife
Turn, completes the cutting of the paper of predetermined breadth.After the completion of cutting, driving knife motor is closed, is retracted from moving knife feeding gas cylinder rod, from
Moving knife returns to safe distance.
Method is detected and controlled to the device location below with reference to Fig. 9 to be described in detail, in this instance, the first carving knife
Group uses the mounting means of mirror image, so that S in this example1Shift value be negative value:
1. the determination of knife position zero point: as shown in view under Fig. 9, with X on the left of grating scale0Place is measurement zero point.First component
The workbench of cutter is fixed, and the micro-displacement from moving knife can be only adjusted by fine tuning cylinder.Forward looking laser sensor arrives
The distance L of zero point1It immobilizes, displacement S of the sensor measurement from moving knife knife face relative to its detection position1.Then first group it is driven
Knife is (L relative to the displacement of zero point1+S1), the displacement is as other groups from the important parameter of moving knife conversion relation.It needs to illustrate
, S in this instance1It is negative displacement for the displacement occurred from grating scale distal end to measurement zero point.
2. other each carving knife initial positions determine: 1. second group of carving knife initial position detection: with grating reading in Fig. 9
Measurement point of the first side as reading head after booting, is arranged in the grating reading head detection cutter on rear side of cutter workbench and works
Platform position X2, while driven by program forward looking laser sensor detects second group and examines from moving knife knife face relative to forward looking laser sensor
Survey the relative displacement S at position2, this two groups of data are input in control system by data line, before system is according to setting
Set the distance between laser sensor detection position and grating head detection position D2(this distance will not change) passes forward laser light
The relative displacement S that sensor detects2It is added therewith, while the position X with grating reading head detection2It is added to get left side the has been gone out
The position of one group of slave moving knife as benchmark, i.e. (S2+D2+X2), using this position as the initial position of second group of carving knife.②
Third component cutter initial position detection method is identical as second group, i.e. (S3+D3+X3).3. the work of the 4th group of carving knife carving knife
Make that platform is fixed, the micro-displacement from moving knife can be only adjusted by fine tuning cylinder.Therefore, the one or four group of carving knife away from
It is total breadth A from constant.
3. inputting the conversion of breadth and displacement: inputting breadth parameter A in control panel1、A2(total breadth A is determining
, it need to only input two kinds of breadth parameter A1、A2, third group breadth A3Pass through (A-A1-A2) realize), system starts to convert,
Start first breadth A with left side1For, in the ideal situation, the reduction formula of breadth and carving knife initial position is A1=
(S2+D2+X2)-(L1+S1).That is X2=A1+(L1+S1)-(S2+D2)。
4. the driving of motor: starting first breadth A with left side1For, system is by X2Numerical value issue control servo motor
Slave computer on, by servo drive circuit control servo motor movement, due to the influence of driving error and sensor accuracy, meeting
There are small error, i.e. A1Not equal to (S2+D2+X2)-(L1+S1).If the practical attainable breadth of institute is A1’=(S2+D2+
X2’)-(L1+S1).Then actual displacement is X2’=A1’+(L1+S1)-(S2+D2).This displacement passes through grating scale by grating real-time monitoring
The signal of feedback, system is by desired displacement X2With actual displacement X2' compare, after the range for reaching permission, issues instruction and pass through
Servo drive circuit enables servo motor stop.
5. the control of aim at tool operation: when first powering on, system is by forward looking laser sensor to S1、S2、S3After determination, pass
Sensor is not just then turned on, and is with S1、S2、S3Constant, the determination of carving knife displacement is by the detection of grating head and system is above-mentioned changes
It calculates to realize.When tool wear needs to be finely adjusted by finely tuning cylinder, started by control panel to knife order, system is just
Starting forward looking laser sensor is adjusted the distance S1、S2、S3It is detected again, the numerical value before covering reaches modified purpose.
As shown in figure 9, being briefly described below to motion control process.It will be clear that common for this field
Technical staff, circuit design and program code involved in following control process are easy to accomplish, and circuit design and journey
