Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, chain conveying line 100 and friction-driven travel line 200(and main driving travel line) before and after install successively, the direction of arrow is throughput direction; The encoderless control synchronization system that the utility model proposes, comprises the first travel switch 1, second travel switch 2, third trip switch 3 and fourth line journey switch 4; Described first travel switch 1 is arranged on chain conveying line 100 exit, and described second travel switch 2, third trip switch 3 and fourth line journey switch 4 are successively set on friction-driven travel line 200 exit.Second travel switch 2, third trip switch 3 and fourth line journey switch 4 be one, interval distance installation slightly each other.
Electric principle of the present utility model is see Fig. 2, and described first travel switch 1, second travel switch 2, third trip switch 3 and fourth line journey switch 4 be connection control device respectively; Controller is connection chain strip transmission line frequency converter 5 and friction-driven travel line frequency converter 6 respectively.The drive motor of the mouth chain travel line 100 of described chain conveying line frequency converter 5; The drive motor of the output termination friction-driven travel line 200 of described friction-driven travel line frequency converter 6.Its middle controller adopts PLC.
First travel switch 1 is arranged on chain conveying line 100 exit, is used for detecting the spreader position on chain conveying line 100, also stops using as chain conveying line 100 simultaneously.
Second travel switch 2 is used for reset chain strip transmission line 100 to be stopped, suspender on such as chain conveying line 100 has triggered the first travel switch 1, and the suspender on friction-driven travel line 200 does not also reach first travel switch (i.e. the second travel switch 2) place in its exit, so just illustrate that the spreader position of chain conveying line 100 is advanced, need to stop, wait for that the suspender of friction-driven travel line 200 can start after reaching the second travel switch 2, this second travel switch 2 mainly prevents the suspender on chain conveying line 100 from occurring answering back to the situation of main driving suspender too in advance.
Third trip switch 3 is used for changing the speed (in this example, the speed of friction-driven travel line 200 does not change) of chain conveying line 100, makes chain conveying line 100 speed can keep relative synchronization with friction-driven travel line 200; In theory when chain conveying line 100 and friction-driven travel line 200 absolute synchronization, first travel switch 1 and third trip switch 3 all trigger at synchronization, but because the motor of the motor of chain conveying line 100 and friction-driven travel line 200 is in continuous running, be bound to there is error, time, longer accumulated error was larger, in the course of time the suspender on friction-driven travel line 200 is not caught up with regard to the suspender that there will be on chain conveying line 100, or the suspender on suspender sinciput friction-driven travel line 200 on chain conveying line 100.The sequencing that can trigger according to the first travel switch 1 and third trip switch 3 adjusts the speed of frequency converter thus eliminates accumulated error, to reach synchronous object.
Fourth line journey switch 4 is used as the stopping of friction-driven travel line 200, if the suspender on friction-driven travel line 200 has triggered fourth line journey switch 4, and the suspender on chain conveying line 100 does not also trigger the first travel switch 1, so illustrate that the speed of chain conveying line 100 does not catch up with friction-driven travel line 200, friction-driven travel line 200 now stops waiting for chain conveying line 100 with regard to needing, and the speed of chain conveying line 100 needs to carry out adjustment quickening.
Concrete control process of the present utility model is as follows:
1) if chain conveying line 100 triggers the first travel switch 1 with suspender and friction-driven travel line 200 suspender does not trigger the memory of the second travel switch 2, so illustrate that chain conveying line 100 is relatively fast, chain conveying line 100 stops wait, wait for that friction-driven travel line 200 triggers the second travel switch 2, and controller cuts the operation of corresponding frequency to chain conveying line frequency converter 5;
2) if chain conveying line 100 triggers the first travel switch 1 with suspender, the now not triggered third trip switch 3 of triggered second travel switch 2 of friction-driven travel line 200 suspender, while so chain conveying line 100 and friction-driven travel line 200 run, controller cuts corresponding frequency to chain conveying line frequency converter 5 and runs;
3) if chain conveying line 100 triggers the first travel switch 1 with suspender, now triggered second travel switch 2 of friction-driven travel line 200 suspender and third trip switch 3, not triggered fourth line journey switch 4, while then chain conveying line 100 and friction-driven travel line 200 run, to chain conveying line frequency converter 5, controller adds that corresponding frequency is run;
4) if chain conveying line 100 does not trigger the first travel switch 1 with suspender, and friction-driven travel line 200 suspender triggered fourth line journey switch 4, so main driving travel line (friction-driven travel line 200) needs to stop wait, until the suspender on chain conveying line 100 can run after triggering the first travel switch 1.In such cases, to chain conveying line frequency converter 5, controller adds that corresponding frequency is run.
In above-mentioned control process, when chain conveying line 100 suspender triggers the first stroke trigger switch 1, friction-driven travel line 200 suspender all can just operate in before and after third trip switch 3, can not occur the increasing situation of accumulated error again, like that just reach synchronous effect.
