Coil of strip is transported to movement.
Turning now to Fig. 3, Fig. 3 shows that the cold-strip steel flexibility of the present invention batches preparation control method
Ultimate principle.The control method batches preparation system suitable for cold-strip steel flexibility discussed above.
Specifically, the cold-strip steel flexibility is batched preparation control method and is included：
Step 301：According to the thickness of the strip steel, select the reel with jaw and described help volume
One of machine carries out batching preparation；
Step 302：When the wrapper is selected, the wrapper is made to rise in the mandrel of the reel
Rotated after reaching position at a slow speed, jaw positioned, in strip steel with threading speed by clamping and conveying device by band
Steel along threading guide plate will take the lead and send into wrapper direction while make above-mentioned wrapper advance in place；
Step 303：When the reel with jaw is selected, the mandrel of the reel is shunk so that pincers
Mouthful open, then reel rotation jaw is positioned, after the completion of positioning, strip steel with threading speed by
Strip steel will be taken the lead to send into jaw by clamping and conveying device along threading guide plate, and then mandrel spreading is so that jaw is closed
Clamping is taken the lead.
For example, Fig. 4 shows that the cold-strip steel flexibility of the present invention batches one of preparation control method preferably
Embodiment.The embodiment can include：
The first step：When possessing operation and helping volume to prepare the automatically condition of step, threading guide plate according to criterion 1,
By mode is batched under batching in artificial selection's employing still, program setting default situations are above to batch mode,
Then start to swing to the height of requirement according to the oscillating table for batching mode guide plate for selecting, when detecting
In place after signal, shovel head plate starts to stretch out；Outer support rises simultaneously.When detecting shovel head and outer support
Stretch out after signal is all on board, into second step；
Second step：Select to help volume using strap rolling-assisting or jaw according to the automatic or manual pressure of criterion 2；
3rd step A：Using strap rolling-assisting mode, first the mandrel spreading of reel in place after, batch
Machine rotates at a slow speed, and then reel rotation is positioned to jaw, in strip steel with threading speed by pinching dress
Put by strip steel along threading guide plate will take the lead send into wrapper direction while, wrapper advance in place, then
Mode is batched up and down according to what criterion A (with criterion 1) determined selection, will be corresponding according to the mode chosen
Pumping arm action is pressed onto position, then tightening belt is controlled according to criterion 3, and detection is in place after signal
Volume belt is helped to tighten up, tightening force is carried out automatically according to program setting, the tensioning pressure of volume belt is anti-when helping
Feedback signal in place after, help volume to prepare automatically step and completing, into strip steel automatic rolling pattern.
3rd step B：Volume mode, the first mandrel of reel is helped to shrink using jaw, i.e., jaw is opened,
Then reel rotation is positioned to jaw, and after the completion of positioning, strip steel is with threading speed by clamping and conveying device
Strip steel will be taken the lead to send into jaw along threading guide plate, then mandrel spreading, i.e., jaw is closed clamping and taken the lead,
Mode is batched up and down further according to what criterion B (with criterion 1) determined selection, will correspondence according to the mode chosen
Upper lower compression roller be pressed onto position, detection helps volume to prepare step automatically after signal in place and completing, turnover reel rotation
Strip coiling pattern.
Criterion set in this embodiment is preferably included to batch selecting criterion, jaw up and down and helps volume
Device selecting criterion, help volume belt tension part power selecting criterion.
For example, this batches selecting criterion up and down for criterion 1, and criterion 1 can be adopted in automatic control system
Artificial selection is taken, is automatically selected also dependent on the implied termss of setting, the condition of selection is lower work
Sequence user specifies and requires or selected according to strip steel datum level quality condition.
For example, the jaw and winding apparatus selecting criterion is helped for criterion 2, criterion 2 is automatic control system
Setting implied termss, select to help volume control using jaw when incoming band steel thickness is more than or equal to 2.5mm
Method, selects using strap rolling-assisting control method when incoming band steel thickness is less than 2.5mm.Control system
System is provided simultaneously with carrying out the pattern of manual intervention selection according to specific needs.
For example, it is criterion 3 that this helps volume belt tension part power selecting criterion, and criterion 3 is to help volume belt
The setting relation of tight part power.In the case where volume state is helped, pressure feedback value (MPa)=(1-4) * strip steel of setting
Thickness (mm).Under returns state, pressure feedback value (the MPa)=2-3 of setting.In the standby state,
Pressure feedback value (the MPa)=1-2 of setting.
Above-described embodiment is available to those of ordinary skill in the art to realize or use the present invention, this
Field those of ordinary skill can without departing from the present invention in the case of the inventive idea, to above-described embodiment
