The beneficial effects of the utility model: this kind ROTARY SCREAM PRINTING automatic design register Adjustment System, can carry out PREDICTIVE CONTROL to the error of the wrong flower of printing and dyeing, and detect in real time and FEEDBACK CONTROL adjusting effect, real-time is better, and reliability is higher.But also can finish stamp net tube initial alignment automatically, and the control parameter is adjustable, is convenient to be connected with the original control system of equipment, and versatility is good.
Description of drawings
Fig. 1 is the area array CCD camera layout.
Fig. 2 is that actual flower returns the length computation schematic diagram.
Fig. 3 is the connection block diagram of ROTARY SCREAM PRINTING automatic design register Adjustment System.
The specific embodiment
Below in conjunction with Fig. 1 to Fig. 3 the utility model is elaborated:
ROTARY SCREAM PRINTING automatic design register Adjustment System comprises
The host computer operation interface comprises touch-screen and image display, is used to monitor the on-line operation state, adjusts control parameter, initialization system software and carries out artificial online speed governing;
IMAQ and processing unit comprise area array CCD camera and image processor, are used for spending back dynamic acquisition, processing and the error output of mark;
Master controller, the calculating of be used for actual calculating of spend back error in length before the stamp, adjusting back stamp error reaches to be controlled the adjustment of stamp net tube speed;
Encoder, encoder in printing and dyeing drive in service and rotate synchronously with fabric, trigger control according to the output umber of pulse of encoder to area array CCD camera by fabric;
Described master controller links to each other respectively with touch-screen, image processor; Area array CCD camera links to each other with image processor, and image processor also links to each other with image display.
More preferably: area array CCD camera is made up of a camera 1 and No. two cameras 2, and No. one camera 1 is positioned at the position of spending back length S apart from the standard in stamp net tube 3 front sides, and No. two camera 2 is positioned at stamp net tube 3 rear sides; One, No. two cameras are dynamically gathered by optical lens respectively and are spent back mark.Here it is the distance that stamp net tube 3 is passed by on fabric when rotating a circle that the flower of talking about returns length.When spending back mark to be ROTARY SCREAM PRINTING, corresponding each spend back on two edges of fabric, stamp some such as marks such as letters.
Image processor is used for the flower that the treated side array CCD camera collects and returns mark, can directly export and spend back the mark error signal.Master controller adopts Japanese Keyemce PLC, adopts DSP double-core control chip.
Next how ROTARY SCREAM PRINTING automatic design register Adjustment System is carried out flower adjustment is set forth:
At first, the several terms that relate to are defined.
1, standard is spent back length S: i.e. stamp net tube girth.When the gait of march of stamp net tube linear velocity and fabric is identical, actually spend back length to equal standard to spend back length.
If the gait of march of fabric is greater than stamp net tube linear velocity, then reality spends back the length overgauge to spend back length.
If the gait of march of fabric is less than stamp net tube linear velocity, then reality spends back length to spend back length less than standard.
2, spend go back to mark standard sample position: the flower that is pre-stored in the image processor goes back to the position that is marked in the shooting visual field.
3, spend back the mark error: actual photographed to flower return and be marked at the physical location of taking in the visual field and spend back the difference of mark standard sample position.
As shown in Figure 1, a camera 1 is installed in standard of stamp net tube front distance stamp net tube and spends go back to length S position, finishes the detection of spending back mark and output and spends back the error delta of mark standard sample position by area array CCD camera and image processor.
As shown in Figure 2, actual photographed to flower go back to when being marked at the physical location 4 of taking in the visual field and spending go back to mark standard sample position 5 to overlap Δ=0; Actual photographed to flower return and be marked at the physical location 4 of taking in the visual field when spend back mark standard sample position 5 afterwards, Δ is for just; Actual photographed to flower return and be marked at the physical location 4 of taking in the visual field before spend go back to mark standard sample position 5 time, Δ is to bear.It is Δ 1 that the flower that once photographs before supposing returns the mark error, current shooting to flower to return the mark error be Δ 2, encoder output umber of pulse is N between twice shooting, a pulse fabric of the every output of encoder travel distance is 6, and the then current actual flower that to be ready entering stamp net tube returns length and standard spends back the deviation of length to be:
Δ Q=N δ+Δ 1-Δ 2-S formula (1)
Master controller is realized wrong flower correction according to spending back deviate Δ Q that stamp net tube speed is predicted adjusting.
Spend adjusted printing quality to detect through mistake by No. two cameras 2 after being installed in stamp net tube, if it is Δ H that the flower that detection obtains returns the mark error, encoder output umber of pulse is M when triggering shooting, then actual photographed to flower return the distance of mark and stamp net tube axle, and the flower of setting returns mark and to the deviation of the gauged distance H between stamp net tube is:
Δ P=M δ+Δ H-H formula (2)
Master controller PLC further adjusts stamp net tube speed according to deviate Δ P, realizes second compensation.
Regulate and the second compensation adjusting by prediction, realized the full cut-off ring control that automatic design register is adjusted.Adopt hand push button in the original control system of circular screen printer to send the mode of pulse signal to the adjustment of stamp net tube speed, made things convenient for the improvement of original system.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
