Develop as the high speed that feeds category to pack an industry, beverage of more and more world brand fruit juice produce business to hope to produce speed to obtain high speed to produce profit through increasing entire line. 2 mark craft 2.

Plant of color print of course of craft of a mark is thermoplastic and plastic brand packages data with coiling material form is offerred makings. The function of the machine that cover sign is the canister mark is retreated automatically roll cut off, accurate cover container to realize a mark to pack, the path after turning heats up contractive working procedure, label perfect and fixed Yu Rong implement proper place, if pursue,1 is shown. Graph course of craft of a mark 2.

The 2 process that cover sign (1) principle of the machine that cover sign and craft are as follows: Sensor 1: Mark Check; Sensor 2: Cutter Check; Sensor 3: Bottle Check; Servo 1: Send label; Servo 2: Cut sign. (2) craft describes as follows: When Sensor 3 feeling measures bottle, motor1 starts, begin to send label; Measure Mark when Sensor1 feeling, motor1 stops to send label; Motor2 starts cut sign. Send label, the bottle in the process that cut sign stops ceaselessly. If the graph is shown 2 times,cover mark automation technological process. Graph stage of Nextpage3 of flow of 2 mark automation amounts to high speed to cover mark automation system to apply a stage to amount to controller of ASDA-A2 high-powered servo send the mark, system that cut sign, can make the speed that cover sign achieves 600 ～ 800 bottles / Min. If the graph is shown 3 times,plan is designed. Graph 3 high speed cover mark plan to design 3.

1The ASDA-A2 that stage of system of ASDA-A2 servo drive amounts to a company to was rolled out later 2000 is new-style driver of servo of high accuracy network communication, it is automation of high accuracy of implementation high speed the crucial campaign that covers sign controls a system, the characteristic is as follows: (1) norms of high resolution coder: Offer 20bit increment coder; Accord with the requirement that needs equipment of machinery of pilot of careful fixed position. In addition, ASDA-A2 also supports additionally absolutely model coder, when the stage cuts off the power, contented client computer can be remembered show buy of v/arc be on the throne, more extensive use occasion is offerred on positional control. (2) network control framework: In the light of at present global labour accuses a group the control demand to high speed network, ASDA-A2 besides the communication specification that can provide standard Modbus, still support CANopen(1M Bps) and FlexRay(10M Bps) standards of two kinds of communication. Hardware interface enters the RJ45 port that sheet gives for sheet, can obtain control of high speed of couplet of much axis . (3) powerful inside seat mode: ASDA-A2 promotes the inside seat of standard ASDA-A series mode function, offer " the position controls an editor " ; Inside seat cache implement by increased formerly at 8 o'clock, the number inputs check the number (DI) increases to 14 o'clock, positional control kind moves to the dot by simple and easy dot mode, promote to a high office can undertake between 2 o'clock by parameter set speed alternates, the bouncing set that different even position nods. Satisfied a client greatly to " servo driver " functional requirement. (4) electronic cam editor: ASDA-A2 offers electronic cam journey to plan, software part offerred travel editor to be able to allow method of program of handlers proper motion, parameter part can choose drive shaft origin, satisfy the functional requirement of client diversification. (5) ASDA-Soft monitoring software: The monitoring oscillograph of 4 groups of channel, the data that provides 16bit measures a data, pass through USB1.

The hardware interface of 1, can achieve the function that seasonable inspect sees. On parameter editor, parameter data the volume improves 32 Bits, provide more functional set. 3.

2 send mark and cut mark to send mark and the servo that cut sign to break away from superstratum to control systematic PLC, spark through DI by machine stage sensor the athletic control of servo of implementation of program of servo controller interior. Reduce needless time loss, in order to satisfy the requirement that high speed covers sign. Servo controls mode: Pr mode (in-house register commands mode) (1) send label: Use PR pattern, open a COMPARE, CAPTURE function piece. Send mark to start: Should feel when measuring bottle, use incident to spark EV1 (Sensor3) spark movement of servo sending label, begin to send label, EV2 sparks PR parameter writes COMPARE and CAPTURE control parameter, open a CAPTURE function to undertake color patch capture, will control mark to grow by the Sensor1 that pay mark. Send mark to stop: When Sensor1 feeling measures Mark, PR uses the method before CAP locates the command is inserted. (2) cut sign: Use PR order, incident sparks. After sending mark to finish, the target position that uses servo sending label arrives at signal DO to spark directly movement of the servo that cut sign. 3.

3 craft difficulty is analysed (1) PLC program place takes memory, extend the circular sweep time of the program, incur loss through delay cuts the behavioral time of mark and suffix. (2) because high-speed asks, at least 0.

1s is about to complete the action that cover sign, requirement suffix must rise often with the electric machinery that cut sign stop, fixed position essence is accurate. (3) of label be out of shape, feeling measure implement the reason such as misoperation causes those who send mark length to forbid. 3.

4A2 servo covers mark performance dominant position (1) 1KHz frequency is wide answer. (2) Mark capture uses module of function of servo interior Compare + Capture. Below Capture function, signal of the DI that pay mark (answer time to be 1um) only direct join of as strong as servo controller put oneself in another's position sparks, in order to increase the behavioral time of servo. Of Compare module open a misoperation that can avoid effectively to catch mark Sensor. (3) control parameter is written, need not with go up a machine communication, can spark by external event A2 drive and Pr program, undertake parameter is written, answer seasonable sex to rise greatly. Graph Nextpage4 of 4 layout plan covers sign servo is debugged 4.

Speed of 1 servo sending label sends mark servo to use two paragraphs of rate: In order to shorten slowdown time. The first paragraph of =1700r/min; Wide =130 of frequency of =1000r/min(of the 2nd paragraph of speed, JL=4) . What one cycle goes pulse to be about 10000 (1 turn) , assume D=40mm of diameter of gyro wheel sending label. Corresponding and real mark grows =3.

14*40*1=125mm(rotate speed compares 1: 1) , if pursue,4 are shown. Graph speed of 4 servo sending label 4.

Wide =150 of frequency of Speed=650r/min (of speed of the 2 servo that cut sign, JL=4) . What one cycle goes a distance to turn for 1/4 (rotate speed compares 1: 1) is shown 5 times like the graph. Graph speed of the 5 servo that cut sign 4.

3 send mark to cut sign system to send mark and the undee plan of the servo that cut sign integratedly, reach send / graph of the system that cut sign is shown 6 times like the graph. Graph 6 send / speed of the system that cut sign this plan uses 5 last words after the stage amounts to function of process designing of interior of high-powered A2 servo and special intelligence module, whole send the mark, process that cut sign to be broken away from completely go up the control of a machine, simplify PLC program, make servo more rapid to catching the mark, processing that sends the mark, signal that cut sign, raised overall response speed, classics test, applied stage amounts to A2 high-powered servo, send mark and the whole cycle that cut sign to be 80ms, can make the speed that cover sign achieves 750 bottles / Min.
