Embodiment
As shown in Figure 1, the utility model provides a kind of paper pulling device of paper cutter embedded Control and drive unit, it comprises logic control element, servo unit and synchronous drive mechanism, described servo unit links to each other with this logic control element and synchronous drive mechanism respectively, this synchronous drive mechanism with push away the paper machine and link to each other.
Described logic control element and servo unit walk abreast, work alone, and the two all openly has the external digital communication interface, can support the visit of various paper cutter computer or print stream waterline watch-dog synchronously.
Described logic control element comprises programmable logic controller (PLC) (PLC) and sensor.Wherein, described sensor comprise cut, motion detection such as platen, supporting plate with switch and handwheel, stripping, add the sensor unit that wet goods detects usefulness, be mainly used in detection machine each present located position, functional entity unit and motion state thereof.Described programmable logic controller (PLC) (PLC) is respectively by linking to each other with sensor and security control unit.This programmable logic controller (PLC) (PLC) by sensor senses air cushion, handwheel fine setting, platen, duty such as cut, trigger servo unit by I/O signal (non-high-speed pulse) and carry out the feeder location according to computer instruction, and detection servo motion state, comprehensively carry out logic determines, provide the control enable signal of other working cell of paper cutter.
Described servo unit comprises servo-driver (SERVO Driver) and servomotor (SERVO Motor), this servo-driver and servomotor are connected with sensor cable by the power cable of motor, this servo-driver closed loop drives servomotor and drives leading screw and then drag the feeder motion by synchronous drive mechanism, reaches the purpose of control feeder location.
Servo-driver is connected with paper cutter computer man-machine interface (HMI) by digital communication mode, receive the definite position of feeder location, and drag feeder at the trigger pip rear drive motor that scans PLC and seesaw, servo with self working state signal such as work enable, be ready to, information such as target location arrival, target velocity arrival, fault notifies PLC in the I/O mode.
Described synchronous drive mechanism comprises servomotor rotatablely moved and is converted into synchronous pulley that feeder seesaws, mechanisms such as band, leading screw synchronously.Servomotor self has sensors such as scrambler or rotary transformer, so do not need to choose separately and install scrambler, has reduced the installation complexity, has alleviated labor strength; Use synchronous drive mechanism can ensure the precision of servo positioning sensor for the feeder location survey; For reducing the noise that produces in the synchronous band transmission process, paper pulling device of paper cutter embedded Control of the present utility model and drive unit are selected the synchronous pulley of inhaling the effect of making an uproar for use and are with synchronously, with the noise that guarantees to produce when feeder runs up.
Cut in the technology the special of paper cutter, to feeder forward and action backward strict requirement is arranged, do not allow overshoot such as pushing away paper forward, when pusher paper, to at first consider the paper on the backstage is pushed to the foreground, shift onto backward afterwards above the target location, returnly more at last push away paper forward to the target location, referring to Fig. 2 and Fig. 3, if use conventional Control on Communication mode to guide servo Electric Traction, each communication process generally can take the above call duration time of 50ms at least, for pushing away paper forward, the utility model dynamic response is general, but for shown in Figure 3 to pusher paper curve, conventional servo will just can finishing with 3 communication processs, promptly the 150ms time is used for the positional information communication at least, but the peculair motion curve customization function that the utility model utilization carries can be finished with 1 communication process, be 50ms, the mode that the user can use programming in advance with particular curve be solidificated in servo in, use the I/O triggering mode directly to call during use, this curve calling function has improved the dynamic response effect of feeder greatly.
Described PLC is the logic core of feeder and other functional unit couplings of paper cutter, it is connected with HMI by digital communication mode, be used to receive HMI for pushing away paper, air cushion, cut, stripping, the action command or the enable command that add the wet goods machine operation, after receiving instruction, PLC at first scans current machine works state, whether the condition of judging execution command satisfies, push away paper according to operative norm or triggering feeder afterwards, or open, close air cushion, or enable platen, cut, stripping, add wet goods, and such control or enable signal exported to security control unit by output point, with other functional units of control paper cutter.
Below the control method between PLC and the servo unit is described below:
At first, in servo-driver, the user adopts the mode of programming to customize nearly 256 kinds of curve movements, and gives the binary code numbering corresponding with them, represents article one curve as 0,000 0001, and 00000110 represents the 6th curve; Secondly, the user is mapped to the curve trigger register on the digital input point of servo-driver one by one by position from low to high, is mapped to DIN1 (digitalinput) as lowest order, and second is mapped to DIN2 or the like; Once more, in logic control element, use the output point of PLC to carry out binary coding, according to the output of encoding of the different instruction of computer, when calling the 10th curve as needs, just coding output 0,000 1010, servoly will move the 10th curve according to mapping table automatically.Be noted that, can call mutually between each curve of servo inside programming, this calling do not need I/O to trigger, do not need Control on Communication yet, such as, finish paper cutter when pusher paper, the servo curve that pushes away paper forward that at first calls, and after finishing, calls automatically this curve to pusher paper curve, after the second curve is finished, call the 3rd curve automatically, like this, only need the communication binary coding of a logic control element to trigger, just can finish the special process curve that three curves are formed, save the working time of 100ms.
Paper pulling device of paper cutter embedded Control of the present utility model and drive unit have adopted the system architecture of Embedded control parts and networking, embedded is the process equipment of simplifying customization according to industry spot, make that the functional unit function is clearly demarcated, independent, concurrent working, work load is light, degree of disturbance is little mutually, and collocation rationally; The structure of networking comes from each equipment and supports the synchronous communication of multiple digital communication interface simultaneously, when finishing feeder control, can support telecommunication, for Design of Production Line and the construction of company information network are laid a good foundation.
