Embodiment
The utility model is further described with operation principle below in conjunction with the accompanying drawings:
One kind as shown in Figure 1 is used for continuous production line shearing threading control system, and its continuous production cable architecture is:Shearing
Before devise pressure roller 11, by magnetic valve 21 and cylinder 22 come realize open and close;Pinch roll 12 is live-roller before cutting, and is passed through
First motor 13 drives.Pressure roller 11 is depressed before shearing, and the pinch roll 12 through before cutting of strip 1 enters flying shear 31, according to production requirement
Excision is end to end and sample.While cutting off end to end, guide plate 32 is fallen by the control of magnetic valve 23 and cylinder 24, the waste material of excision
Taken advantage of a situation landing with sample.Shearing finishes back guide 32 and is raised to horizontal level again, takes the lead to continue forward by the support of guide plate 32
Threading, by the idler roller 33 without driving, enter through the turning, clamping and conveying roller 15 that the second motor 16 drives, pressure roller 14 during threading
Strip 1 is clamped by magnetic valve 25 and the pressure of cylinder 26, strip 1 enters coiling machine 18 by turning, clamping and conveying roller 15, and coiling machine 18 is logical
The 3rd motor 17 is crossed to drive.
A kind of threading speed Discrete control for continuous production line shearing threading control system as shown in Figure 2 is illustrated
Figure, it often does one-off by NUSCO-300 type Frequency Converter Controls flying shear 31 and is issued by a pulse signal, passes to PCS7
Control system, PCS7 control systems add up to the number of shearing, and letter is finished if reaching predetermined number and being issued by shearing
Numbers 101, the 105-1 of the delay retainer input module I input shearings of delay retainer 105 finish signal 101, and the delay is kept
The 105-3 of the delay retainer input module II input retention times signal 102 of device 105, the input of retention time signal 102 are
“4s”.The delay retainer(105)Delay retainer output module(105-2)By retainer output signal(106)Transmission
To selection control(107)Selection control input module I(107-1), the selection control(107)Selection control
Input module II(107-2)Input threading rate signal(103), the selection control(107)Selection control input mould
Block III(107-3)Input master control command signal(104), the selection control(107)Selection control output module(107-
4)By selection control output signal(108)Input converter, respectively as the first motor(13), the second motor(16), the 3rd
Motor(17)Speed setting value.
The utility model is used for continuous production line shearing threading control system at work:Used first by TON functional blocks
Input through keyboard " 4s ", retention time signal 102 is dealt into the 105-3 of delay retainer input module II of delay retainer 105,
NUSCO-300 type frequency converters are given when flying shear 31 often does one-off and is issued by a pulse signal, pass to PCS7 control systems,
PCS7 control systems add up to the number of shearing, finish signal 101 if reaching predetermined number and being issued by shearing, work as guarantor
When holder output signal 106 is "true", the 15m/min loop of threading rate signal 103 is selected, in the input of corresponding functional block
End, with input through keyboard " 36 ";When signal 106 is " non-", the loop of master control command signal 104, master control command signal are selected
104 are sent by WINCC action pane, in the speed of service value that WINCC action pane is manually inputted in producing line
.Selection control output signal 108 sends signal to frequency converter by output lead, respectively as the first motor 13,
Second motor 16, the speed setting value of the 3rd motor 17.By the adjustment of retention time signal 102, threading rate signal 103,
Can adjust take the lead advance speed, make up guide plate because air pressure fluctuation or deadweight caused by lifting it is slow the defects of, so as to avoid card
Production accident caused by steel.
Principle of the present utility model:Flying shear 31 is 1.63 meters by the distance of guide plate 32 to idler roller 33, from lowest order lifting
It is most fast 2.1 ~ 4.6 seconds to horizontal position.Under normal circumstances summer due to the time of the more stable needs of air pressure it is most short, in the winter time
Or air pressure it is unstable when time for needing it is most long.So need the speed of service of strip 1 control after shearing reasonable at one
In the range of.Process is as follows:Advance 1 meter when having sheared to run 4 seconds with 15 m/min speed;Even if the lifting of guide plate 32 compared with
Slowly, then run 0.6 second and advanced 0.3 meter with 30 m/min speed;Take the lead also have 0.33 meter of distance apart from idler roller 33, will not be by card
Below idler roller 33.
