Define the inclined angle alpha of plume 8 in 8 conveyor belt of plume are as follows: straight line where the long side of plume 8 and conveyor belt are run
The angle of the vertical line in direction.0 °≤α≤90 °, inclined angle alpha is bigger, then 8 skew of plume is more serious.PLC13 is every time T0It obtains
The distance signal of 1 laser displacement sensor simultaneously stores.
The distance of 8 transfer passage second baffle 10 of laser displacement sensor front end and plume is M, works as laser displacement sensor
When not detecting plume 8, laser beam is irradiated to the second baffle 10 of 8 transfer passage of plume, and laser displacement sensor is examined at this time
The distance signal measured is M, and when there is plume 8 to pass through from laser displacement sensor, laser beam is irradiated on plume 8, at this time
The distance signal detected is less than M.
When the distance signal that laser displacement sensor detects sports the numerical value less than M from M, show laser position at this time
Displacement sensor just starts to detect a cigarette, and the point on plume 8 that laser beam is irradiated at this time is known as the left vertex A of plume 8.
When sporting M from the numerical value less than M when the distance signal that laser displacement sensor detects, show that a cigarette will
Laser displacement sensor is left, the point on plume 8 that laser beam is irradiated at this time is known as the right vertex B of plume 8.
Detect the left vertex A to the right vertex B for detecting plume 8 of plume 8 from laser displacement sensor, i.e., plume 8 from
During laser displacement sensor passes through, the distance signal for the laser displacement sensor that PLC13 is acquired is respectively Z1、Z2、
Z3……ZN, the time interval of each adjacent two signal is T0, the number of signal is corresponding for N, first signal Z1 and left vertex A,
The last one signal ZNIt is corresponding with right vertex B.In the drawings, vertex A is first top that laser displacement sensor detects
Point, vertex B are the last one vertex that laser displacement sensor detects.
(1) m is measured
PLC13 controls four contactors K1, K2, K3, K4 and is attracted, and four motors operate and drive four belt operations, by
It is identical in the speed of four motors, and the diameter of four belt pulleys is also identical, therefore the speed of four belts is also complete
It is identical.
Such as Fig. 4, Fig. 5 and Fig. 6 so that one not crooked cigarette run in conveyor belt, and sensed from laser displacement
Device passes through, during the left vertex A to the right vertex B for detecting plume 8 that plume 8 is detected from laser displacement sensor,
PLC13 is every time T0The number N=m of the distance signal of the laser displacement sensor acquired.
The width of plume 8 is X (bond length), the distance L=X that then plume 8 is run during this；Each adjacent two
The time interval of signal is T0, therefore time T used in the processAB=(m-1) T0；Then the speed that plume 8 is run
The above process only needs to carry out once, proceeds as described above when such as installing the present apparatus for the first time and obtains m value.
(2) when actual motion, 8 inclination conditions of plume are measured
When actual motion, such as Fig. 4 to Figure 17, detect the left vertex A of plume 8 to detecting the right side from laser displacement sensor
During the B of vertex, the distance signal for the laser displacement sensor that PLC13 is acquired is Z1、Z2、Z3……ZN, signal number
For N, the time interval of each adjacent two signal is T0。
Calculate Z1、Z2、Z3……ZNArithmetic average:
Then Z is calculated1、Z2、Z3……ZNStandard deviation
σ0It is a setting value, the value very little to be taken, such as 0.01.
1, as σ≤σ0When.Such as Fig. 7 to Figure 12, Z1、Z2、Z3……ZNBetween deviation it is very small, then judgement should during
Laser displacement sensor has only detected the short side or long side of a cigarette, inclined angle alpha=0 ° or α=90 °.
Time T used in the processAB=(N-1) T0

Then the distance that plume 8 is run are as follows:
Wherein, the width of a cigarette is X (short side), and length is Y (long side).
If the short side of plume 8 passes through from laser displacement sensor, the distance L that plume 8 is run is equal to 8 width of plume
X., whereas if the long side of plume 8 is passed through from laser displacement sensor, the distance L that plume 8 is run is equal to the length of plume 8
Y is spent, therefore compares the size of L it may determine that going out the state of plume 8 at this time, specific judgment method are as follows:

The side detected by laser displacement sensor, BC are the sides that plume 8 is then detected by laser displacement sensor.
Referring to the straight line where the direction that be laser displacement sensor run along plume 8 Figure 18 and Figure 19, DEF, AD,
EC, FB and straight line DEF are vertical.The vertical DA of C is in G, and the vertical FB of CH is in H.
When laser displacement sensor detects left vertex A, distance signal Z1, then DA=Z1。
When laser displacement sensor detects right vertex B, distance signal ZN, then FB=ZN。
Z1、Z2、Z3……ZNIn minimum value be Zn, ZnIt is n-th of signal in N number of signal, signal ZnCorresponding to plume 8
On middle vertex C, then EC=Zn；
Then there are following two formula:
GA=DA-DG=DA-EC=Z1-Zn
HB=FB-FH=FB-EC=ZN-Zn
From laser displacement sensor detect left vertex A to during detecting middle vertex C, the distance signal of acquisition
Number is n, and the time interval between every two adjacent signals is T0, then this process duration TAC=(n-1) T0, cigarette
The speed that item 8 is runThen the distance that plume 8 is run
From laser displacement sensor detect middle vertex C to during detecting right vertex B, the distance signal of acquisition
Number is N-n, and the time interval between every two adjacent signals is T0, then this process duration TCB=(N-n) T0,
The speed that plume 8 is runThen the distance that plume 8 is run
Then there are following formula:
(1) when AC < (X+Y)/2 or BC > (X+Y)/2, such as Figure 18, AC are short sides, and BC is long side, then judge plume 8
Top turns forward.Thus the size at inclination angle can be calculated using following formula.
Or
(2) when AC > (X+Y)/2 or BC < (X+Y)/2.If Figure 19, AC are long sides, BC is short side, then judges plume 8
Lower part turns forward.Thus the size at inclination angle can be calculated using following formula.
Or
The testing process of α is as shown in Figure 20.
