The specific embodiment
Embodiment one
Install two photoelectric tube PH1, PH2 additional unloading the volume place, on the dolly power transmission shaft, install an incremental encoder S1 additional, as shown in Figure 1; The installation site of PH1, PH2 must and be unloaded between the volume stand at dolly; And on same vertical plane, PH1 aloft, PH2 is at lower; The height of PH1 is that the height of PH2 is the below of the highest of dolly between the highest of the highest of dolly and the coil of wire.When coiling when being discharged on the coil stripping car; Dolly is walked to the feeding skid direction; At this moment if coil end face and the dolly justified margin is L0=0; Then PH1 and PH2 almost have signal simultaneously, and L1 is that the distance L 1 of carriage walking when 2# photoelectric tube one has the distance L 2 of signal carriage walking with 1# photoelectric tube one signal to be arranged is poor, i.e. L0=L2-L1.
Guarantee that back one volume can be near last volume, must stretch out the dolly face or flush near unloading skid side panel volume face, i.e. L0＞=0, but can not be excessive, in order to avoid roll out.If L0＜0, then the dolly face stretches out and coils, and dolly is when unloading second volume because the dolly face has been adjacent to last volume, therefore, at this moment two coil can not near, leave the gap of L0.Because the bundling length respectively coiled is different, the central point of therefore coiling is also inconsistent, guarantee that the face of coiling must stretch out the dolly face or flushes, and the position that dolly is return at every turn is also inconsistent.Calculate according to the encoder code value that is contained in dolly this position.
The zero-bit of dolly to unload the volume stand distance be constant, so dolly when unloading the first volume, the travel distance L3 of dolly is constant, stops when promptly carriage walking is to L3, unloads to be rolled onto here.Can be regarded as out the length L of coiling according to photoelectric tube PH1
PJThe i.e. code value L of dolly encoder when PH1 has signal
PH11Code value L with dolly encoder when the PH1 no signal
PH12Poor, L
PJ=L
PH12-L
PH11Then dolly is at the stop position L4=L3-L that unloads second volume
PJAnd the like can calculate the 3rd the volume unload the volume position.
Two photoelectric tube PH3, PH4 are housed on unloading skid, and as shown in Figure 1, dolly photoelectric tube PH4 when unloading the first volume must have signal, and the carriage walking distance L must be more than or equal to L3.When unloading the 3rd volume, photoelectric tube PH3 must have signal, and L must be more than or equal to L
MINJudge whether encoder work is normal, detecting the pulse change amount of encoder each second, if no change or change less than certain numerical value encoder operation irregularity then, otherwise, if it is also unusual to change excessive encoder work.When this situation occurring, then can stop the operative employee who unloads volume and send the announcement of reporting to the police.
The qualified finished product coil of wire of the high-speed rod of present embodiment unload the volume alignment schemes, carry out according to the following steps:
Coil and will unload when volume when the PF line unloads volume station, coil stripping car is unloading the material level rise, coiling picking-up; The dolly holder and is coiled toward the unloading skid walking; The photoelectric tube PH4 that walks has signal and carriage walking distance L more than or equal to L3, and the dolly decline that halts is discharged on the unloading skid coiling;
When unloading second volume, dolly stop position L4=L3-L
PJ-L0, after putting in place, dolly descends, and is discharged on the unloading skid coiling;
Unloaded for the 3rd when volume, photoelectric tube PH3 has signal, and the stop position L5=L4-L of carriage walking distance L when unloading the 3rd volume more than or equal to dolly
PJ
