Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structured flowchart of embodiment of the present invention full-automatic food wrapping machine electrical control gear;
Fig. 2 is the governor system control circuit diagram of embodiment of the present invention full-automatic food wrapping machine electrical control gear.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the structured flowchart of embodiment of the present invention full-automatic food wrapping machine electrical control gear; This electrical control gear comprises PLC, guidance panel, sensing mechanism, frequency variable speed-adjusting mechanism and temperature booster, described PLC is by control bus attended operation panel, sensing mechanism, frequency variable speed-adjusting mechanism and temperature booster respectively, described frequency variable speed-adjusting mechanism comprises Speedless sensor vector frequency converter and motor, described guidance panel is mounted with operating switch, operation keyboard and LCDs.
The PLC of the full-automatic food wrapping machine that the present invention mentions carries out speed control by guidance panel to frequency variable speed-adjusting mechanism, carries out temperature setting to temperature booster; Wherein, the speed governing of Speedless sensor vector frequency converter realizes by the operation keyboard setting running velocity on guidance panel, and by the LCDs display motor speed on guidance panel; Temperature booster adopts 48V safety voltage, and it is set the temperature needing heating by PLC, after design temperature, approximately need 20min can reach the temperature of setting.Follow-up system program is loaded with in the PLC of this full-automatic food wrapping machine, this follow-up system program is accurately located according to the shape of connection with wrapping of piece and size, adopt forward and reverse direction tracing, further increase tracking precision, to the error Timeliness coverage that packing occur in process of production, recompense accurately and correct simultaneously, avoiding the waste of packing.After foods packing machine runs, film mark sensor in sensing mechanism is constantly at detection film mark, detecting position sensor simultaneously in sensing mechanism is constantly at detection mechanical location, two kinds of sensors send the signal detected to PLC respectively, after program computation, exported by PLC and just chase after and instead chase after instruction and control motor positive and negative tracking; In addition, if detect tracking pre-determined number after still can not reach technical requirements, can auto-stop to be checked, avoid the generation of waste product.
The Speedless sensor vector frequency converter that the frequency variable speed-adjusting mechanism of the full-automatic food wrapping machine in the present invention is selected has automatic tuning capabilities, energy auto modification frequency, the effect that during to reach alternation in weight, motor speed is stable, there is higher steady speed precision and fast dynamic response simultaneously, the transmission control overflow of high performance applications can be met, in addition, owing to eliminating speed sensor, maintenance cost is greatly reduced.The speed control loop of this frequency converter is made up of DC injection braking resistance, rotating signal input terminal, crawl signal input terminal, frequency converter failure lead-out terminal and the given potential device of frequency.Fig. 2 is the governor system control circuit diagram of embodiment of the present invention full-automatic food wrapping machine electrical control gear; Wherein, the external braking resistor R0 of DC injection braking resistance terminal P+, DB, makes system realize instantaneous emergency when stopping; Rotate forward the Y0 output signal of signal input terminal FWD reception from PLC, frequency converter is pressed setpoint frequency and is rotated forward operation; Crawl signal input terminal X1 receives the Y1 crawl signal exported from PLC, and frequency converter realizes crawl and runs; Frequency given potential device R1 carries out given frequency setting, facilitates execute-in-place work to carry out speed governing according to need of production; Frequency converter failure lead-out terminal is TA and TC; when a failure occurs; incoming signal COM, X10 of PLC close, and the auto-stop alert program then loaded by PLC inside sends shutdown signal and controls motor stalls, and drives annunciator to send alarm sound.
Present invention is disclosed a kind of electrical control gear of full-automatic food wrapping machine; this electrical control gear is by adopting PLC intelligent control technology and speed sensorless vector control technology; not only drastically increase Accuracy of Packaging and the operation stability of full-automatic food wrapping machine; greatly reduce production maintenance cost, and safe stopping alarm function can be provided when breaking down.
