Abstract
The invention discloses a kind of colour code and put the control method of film, particularly as follows: before Qi Donging, first color punctuation is directed at color spot graph switch；Set the length that σ L finely tunes as every subsystem, take the half of color punctuation width；If the full-length between two colour codes of packaging film is Lmm；Fixed length puts film length every time is Lmm；When PLC detects color punctuation rising edge, PLC runs program and enters into interrupt routine, it is judged that now putting film either with or without completing, being not fully complete if now putting film, illustrate that putting film has crossed color punctuation or just arrived color punctuation, judges that after putting film and completing colour code switchs the most just at color punctuation again.The colour code that the present invention provides puts the control method of film, compared with prior art, puts film precision height, and is not affected by putting film speed, even if packaging film printed patterns colour code has deviation, system also can oneself adjust.
Description
Technical field
The present invention relates to put film mode, specially colour code conventional in a kind of film packer and put the control method of film.
Background technology
What in film packer, we commonly used puts film mode is two kinds: fixed length puts film and colour code puts film.Fixed length is put film and is usually used in
Hyaline membrane is packed, and put film is all certain length every time, and the logic that the operation putting film servomotor is all independently of PLC is swept
Retouching the cycle, precision can meet requirement completely, as shown in Figure 1.Colour code is put film and is mainly used for colour film packaging, puts film every time
Length is by colour code switch detection color punctuation, by PLC logical judgment, then controls the start and stop of servomotor, owing to relating to here
The response time of colour code switch and PLC scan logic cycle of operation, so colour code is put film and is had certain error.
Typically, we utilize the control flow of servomotor to be as shown in Figure 2.This control method has certain error,
And cannot avoid, we set puts film speed as xmm/s, a length of t during scan period of PLC0Ms, the response time of colour code switch
For t1Ms, generally t0Value scope be several milliseconds to a few tens of milliseconds, even about 100 milliseconds, this time and PLC's
The speed of service, the length of program has relation, t1It is usually about one or two millisecond, if color code detection signal delivers to PLC, then warp
Crossing PLC logical judgment, one PLC of signal difference putting film for twice scans cycle of operation, and also color code detection signal differs from a reaction
Cycle, then the error lengths putting film for twice is exactly L1=x*t0/1000+x*t1/ 1000, our x value 400, t0Value
25ms, t1Value 1ms, calculates L=10.4mm, and the error namely putting film for twice has 10.4mm, if putting film speed
Faster, error also can be bigger.
Summary of the invention
The present invention solves that above-mentioned technical problem employed technical scheme comprise that a kind of colour code of offer puts the control method of film,
Particularly as follows:
1), before starting, first color punctuation is directed at color spot graph switch；Set the length that σ L finely tunes as every subsystem, take color
The half of punctuate width；
2) full-length between two colour codes of packaging film is set as Lmm；
3) fixed length puts film length every time is Lmm；
4) when PLC detects color punctuation rising edge, PLC runs program and enters into interrupt routine, it is judged that now putting film has
Not completing, being not fully complete if now putting film, illustrate that putting film has crossed color punctuation or just arrived color punctuation, after putting film and completing again
Judge that colour code switchs the most just at color punctuation.
If not at color punctuation, illustrate that putting film has crossed color spot graph point, puts a length of L-σ L of film next time, if colour code
Switch, at color punctuation, illustrate to put film just, puts film length still for L next time, owing to this judgement is to put after film completes, and institute
It is negligible with the cycle of operation of PLC.
If putting in membrane process whole, colour code switch does not detects color punctuation, illustrates to put film color punctuation delayed, next time
Put a length of L+ σ L of film.
The present invention has the advantages that relative to prior art
Compared with prior art, put film precision height, and do not affected by putting film speed, though packaging film printing figure
Case colour code has deviation, and system also can oneself adjust.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
In this programme, we are in the case of colour code puts film, put based on film by fixed length, further according to the position system of colour code
Automatically it is finely adjusted.
Specific practice is as follows:
Precondition: before 1. starting, is first directed at color spot graph switch by color punctuation.2. σ L is the length of every subsystem fine setting
Degree, typically we take the half of color punctuation width, namely about 3mm.
1, we set the full-length between two colour codes of packaging film as Lmm as shown in Figure 3.
2, each fixed length puts film length is Lmm.
3, when PLC detects color punctuation rising edge, PLC runs program and enters into interrupt routine, it is judged that now putting film has
Not completing, being not fully complete if now putting film, illustrate that putting film has crossed color punctuation or just arrived color punctuation, after putting film and completing again
Judge that colour code switchs the most just at color punctuation, if not at color punctuation, illustrate that putting film has crossed color spot graph point (such as Fig. 4), under
Once put a length of L-σ L of film.If colour code switchs at color punctuation, illustrate to put film just (such as Fig. 5), put film length next time
Or be L, owing to this judgement is to put after film completes, so the cycle of operation of PLC is negligible.
If 4 whole put in membrane process, colour code switch does not detects color punctuation (such as Fig. 6), illustrates to put film color punctuation stagnant
After, put a length of L+ σ L of film next time.
Illustrate: the judgement of above color punctuation is to perform in interrupt routine, and the calculating process putting film length is front
Once put film complete and after once put and perform during film, so the scan period of PLC is negligible, even interrupting
The execution of program has time difference, within we force the adjustment amount every time putting film length to be maintained at σ L.Switch in view of colour code
Response time, the error of this control method is at σ L+x*t1/ 1000, value is 3+400*1/1000=3.4mm.Control stream
Journey figure is as shown in Figure 7.
Although the present invention discloses as above with preferred embodiment, so it is not limited to the present invention, any this area skill
Art personnel, without departing from the spirit and scope of the present invention, when making a little amendment and perfect, the therefore protection model of the present invention
Enclose when with being as the criterion that claims are defined.
