The electric execution devices adopting solenoid valves, in this example, are 12 pieces in total, eight of them are mounted at bottom of the nozzles for controlling the open/close operation, and four of them are mounted in a dye conveyer cabinet for controlling pneumatic source by regulating disc pumps to convey dye material.
The programmable logic controller consists of a CPU (central processor module unit), Siemens 315-2DP), a DI (digital input) module (SM321, 32 points input) and a DO (digital output) module (SM 322, 16 points relay output). Wherein the central processor module unit CPU connects with the servo controllers of the robot via bus interface (Profibus-DP, CPU per se supplied) and the servo controllers connect with the superior monitor computer via CAN bus. The digitals output module DO connects with an enabling terminal of the servo controller via the relay. The digitals input module DI receives the manual or automatic mode selection from the X/Y-axis. The programmable logic controller communicates with the servo controllers via bus. The digitals input module DI receives point start operation within the printing and dyeing plane(spray drawing plane) under manual mode (realizes communication with the servo controllers via PLC); The digitals input module DI receives the start/stop operation under automatic mode and limit switch signal from the robot walking area (X-axis limit switch installed on X-axis rail of the printing and dyeing plane of the robot and Y-axis limit switch installed on the Y-axis rail, communicate with the servo controllers which are realized via PLC) as well. The programmable logic controller acquires limit signals from the servo controllers via bus for manual control. The mode selection switch is mounted on the panel.
The said robot is of one or more groups of plane rectangular structure, each group has X-axis servo motor and Y-axis servo motor controlled by the X-axis servo controller or Y-axis servo controller respectively. The position feedback sensor of each axis servo controller feeds back the robot position signals to the position feedback input terminal of the servo controller. The digit frequency output terminal of the X-axis servo controller connects with the digit frequency input terminal of the Y-axis servo controller.
The said robot installing on the printing and dyeing framework (under which there is cloth to be printed and dyed) is of one or more groups of plane rectangular configuration (two groups in this example). On each group of robot there are X-axis servo motor and Y-axis servo motor controlled by X-axis servo controller and Y-axis servo controller separately (servo controllers in this example are of Lenze EVS 9323 EK and Lenze 9324 EK). The effective travel of X-and Y-axis servo motors form the printing and dyeing plane. The position feedback sensors (in this example they are of rotary transformers) on each axis servo motor feed back the position signals to the servo controller. The digital frequency output terminal of X-axis servo controller connects with the digital frequency input terminal of Y-axis servo controller to realize the speed transmission between X-axis and Y-axis for robot. The enabling input terminal of the servo controller(s) connects with the contact points of the relays controlled by the programmable logic controller. Both the X-axis servo motor and Y-axis servo motor change the rotating movement into rectilinear movement of X-axis and Y-axis via a drive mechanism so as to control the movement of the nozzles in the printing and dyeing apparatus.

In the example, based on the data of printing pattern edited by the superior monitor computer and through displacement on X-and Y-axis, two electronic cams are established individually in the X-axis and Y-axis servo controllers by making use of their interior function block. A virtual main shaft is established in the X-axis servo controller and the speed of the virtual main shaft is transmitted to the digital frequency input terminal of Y-axis servo controller via the digital frequency output terminal of the X-axis servo controller and, in this way, the movement of X-axis and Y-axis by following up the same virtual main shaft is realized and thus achieves a synchronous operation position of robot within the printing and dyeing plane and in turn, the curve data from each electronic cam are downloaded to corresponding data storage area in X-axis and Y-axis servo controllers via the superior monitor computer.
There are graphics user interfaces in the superior monitor computer for man-machine conversation.
Siemens CP5611 PROFIBUS MPI communication card inserting in the superior monitor computer can realize digital communication with the programmable logic controller. Lenze CAN bus controller (USB interface) mainly carries out edition and parameter configuration for the servo system and downloads the printing and dyeing curves to the servo controllers. In addition, the superior monitor computer also carries out the edition and trimming of printing and dyeing curves, the monitoring and readjustment parameters of equipment operation, such as the setting up and modification of virtual main axis speed and etc.
The whole system consists of two sets of plane rectangular coordinates robot, each of which operates independently or operates in interaction with each other.
The dye conveyer apparatus consists of four groups of disc pump supplying dyes in four colors. Each plane rectangular coordinates robot has four groups of nozzles (connected with the programmable logic controller receiving open/close signals as the superior monitor computer sets up the open/close time and sending open/close signals to high-speed solenoid valve). The open/close operations of nozzles are controlled by four high-speed solenoid valves. The open/close time of the nozzles may be set by the superior monitor computer, or linked by reaching to a certain position. Different combinations of nozzle open/close time lead to a diversification of printing pattern.
The programmable logic controller carries out data exchange with the superior monitor computer through MPI bus, carries out data exchange with the servo controllers through PROFIBUS bus, carries out dye conveying, open/close controlling of solenoid valves of each nozzle, the indications of power-on, operation, stop and working status of the whole system through the interior logic program of the programmable logic controller, and supervises the status of the servo controllers through reading the current operation parameters of the servo controllers and transmits these parameters to the superior monitor computer for graphical display.
Since the superior monitor computer is capable of storing the parameters in the whole process of printing and dyeing in the form of formulation so the repeatability of printing patterns may be realized.
The superior monitor computer may carry out remote communication with other equipment through the Ethernet card which is installed on the computer.
As shown in FIG. 2, the control method of the intelligent waterless printing and dyeing control equipment is implemented through the controlling programs storing in the superior monitor computer. The following steps are involved in the main program:
A. Taking the cloth operation direction as Y-axis (the travel of Y-axis is 200 mm in this example) and the direction which is perpendicular to the cloth operation direction as X-axis (the travel of X-axis is 1800 mm in this example) to establish the plane of printing and dyeing.
B. Setting up two electronic cams, i.e., X-axis electronic cam and Y-axis electronic cam in the servo controllers. These two cams are driven by the same virtual main shaft.

As shown in FIG. 3, the edited printing and dyeing formulation includes edited printing and dyeing curve and optimizing printing and dyeing curve, and analyze the optimized printing and dyeing curve; Stimulate the result of printing and dyeing display if the result of optimization meets the technical requirements; Preserve the printing and dyeing curve if the above mentioned result of printing and dyeing is satisfactory; Set up the parameters for the servo controllers(mainly including the X-axis scaling, Y-axis scaling, X-axis speed follow-up coefficient, speed settings of the virtual main axis, number of robot (one or two, if two, then further requirement to set up the movement time delay between the two robots is necessary), the manual/auto working mode of the solenoid valve of the nozzles (can be set up separately or independently) and the parameters of solenoid valve of the nozzles (including manual/auto working mode of solenoid valve of the nozzles, the open/close frequency of the solenoid valve under auto mode, i.e., the open/close time (unit: in second) of the solenoid valve), then return back to the main program.
If the above mentioned result of optimization does not meet the technical requirements of printing and dyeing, return back to the step of optimizing printing and dyeing curve; If the above mentioned effective result of printing and dyeing is not satisfactory, return back to the step of editing printing and dyeing curve.
The editing of printing and dyeing curve can be as follows: to generate regular jet painting through curve function, or to draw a two dimensional jet painting curve in specified area to control a mouse by using a timer, or to form a new jet painting curve by intercepting any piece from the regular curve and hand drawn curve, wherein, a cycle and an amplitude of the regular jet painting curve can be freely set up by parameters. Regular jet painting curves include straight line, sinusoidal, saw-teeth wave curve, parabola curve, semi-circular curve, double semi-circular curve and quadratic curve and etc.
The above mentioned optimizing jet painting curve includes the following steps as shown in FIG. 4: reading jet painting displacement curve; determining whether the jet painting displacement curve is complete (in this example the detailed criteria of determination is: the start point of the displacement must be 0, any point of the coordinates varying range on X-axis displacement curve must be between 0 to 1800, not overstepping the travel range of X-axis, any point of the coordinates varying range on Y-axis displacement curve must be between 0 to 200, not overstepping the travel range of Y-axis). If the result of the above mentioned determination is not satisfactory, trimming the jet painting displacement curve; calculating the varying rate of the jet painting curve in the commencing section; calculating the cycle and amplitude of the sinusoidal which has identical varying rate of the curve; using one-fourth wavelength sinusoidal to replace the original jet painting curve in the commencing section; calculating the varying rate of the jet painting curve in the terminating section; calculating the cycle and amplitude of the sinusoid which has identical varying rate of the curve in the terminating section; using one-fourth wavelength sinusoidal to replace the original jet painting curve in the terminating section. Then calculate the average value of three points in succession by using super-average filtration optimization algorithm for carrying out smooth optimization for X-and Y-axis displacement curves; Finally return back to the sub-program of the editing jet painting curve and continue the step of analyzing the optimized jet painting curve.
The step of analyzing the optimized jet painting curve includes carrying out displacement curve analysis, speed curve analysis, acceleration curve analysis upon the optimized curve and the detailed step is as shown in FIG. 5: reading X-axis and Y-axis jet painting displacement curve on the jet painting curve; determining whether the above mentioned displacement curves meet the design requirement, if an answer is ‘yes’, differentiating X-axis and Y-axis jet painting displacement curve respectively to obtain X-axis and Y-axis jet painting speed curve; determining whether X-axis and Y-axis jet painting speed curves meet the requirements of the servo controllers, if the requirements are met, differentiating X-axis and Y-axis jet painting curves respectively to obtain X-axis and Y-axis jet painting acceleration curves; then determining whether the acceleration curves meet the requirements of the servo controllers, when the answer is ‘yes’, it means that the edited jet painting curves are qualified; after that returning back to the sub-program of editing jet painting formulation to determine if the optimized curves are qualified; if at lest one of the above mentioned results of determination is not satisfactory, it means that the edited jet painting curve is not qualified, returning back to the sub-program of editing formulation to determine whether the optimized curves are qualified in the same way as well; however, if the answer of the determination over this step is ‘no’ satisfactory, returning back to the step of optimizing jet painting curve and continue to optimize the said curve; Repeating the process above until the displacement curves, speed curves and acceleration curves have met their own requirements correspondently.
The above mentioned stimulating display result of jet painting is done through loading the optimized curves into the superior monitor computer by curve display controlling piece. The result is as shown in FIG. 6.
D. Downloading jet painting formulation into the servo controllers.
The optimized two dimensional jet painting curve which is edited on the superior monitor computer is broken down into X-axis and Y-axis curves and then further scattered into 64-1024 points (this point range being based on the capacity of the memory of the servo controllers).
The scattered points are downloaded into the memories of the X-axis and Y-axis servo controllers respectively as the X-axis jet painting curve and Y-axis jet painting curve.
E. Starting up the servo controllers and carrying out the operation of jet painting by the electronic cams.
Some regular types of jet painting curves, such as sinusoidal, saw-teeth wave and etc., are stored in the superior monitor computer. Users may use one of them and the same curve with in the whole operation area, each curve can be broken down into sections and then made the beginning and the end combinational connection in the whole operation area. Simultaneously the curve editing and optimizing can be done by means of hand drawing. As the optimized curves are determined, the superior monitor computer will carry out sampling analysis upon the determined curves and download the coordinates of each point, which describe the operation orbit of the curve, into memories of the servo controllers. The X-axis and Y-axis servo controllers then read the jet painting curve data from these memories and drive the X-axis and Y-axis servo motors in the robot to operate within the printing and dyeing plane for jet painting operation.
In practical application the complete set of intelligent waterless printing and dyeing equipment may be simply controlled for jet painting by operating the graphics user interface of the superior monitor computer.
The jet painting operation given in this example is based on the downloaded data of printing patterns from the superior monitor computer and is executed by two electronic cams which are established respectively in the servo controllers based on the X-axis and Y-axis displacement. The synchronization there with is realized through the establishment of virtual main shaft in X-axis servo controller.
