Embodiment
See also Fig. 1,2, the utility model is the online dynamic length measurement system of a kind of steel pipe, comprise control module 5, first sensor 1, second sensor 2, the 3rd sensor 3, scrambler 4, described first sensor 1, second sensor 2, the 3rd sensor 3 and scrambler 4 are connected respectively to four input ends of control module 5, described first sensor 1, second sensor 2, the 3rd sensor 3 is by setting gradually behind the forward direction, scrambler 4 is installed between the first sensor 1 and second sensor 2, the output terminal of described control module 5 is connected to master control computer 6, and the output terminal of described master control computer 6 is connected to printer 7.This system can improve production efficient and measuring accuracy, reduces personnel labor and manufacturing cost.The online dynamic length measurement system of this steel pipe, based on the existing roller-way of producing, need not increases new station, has saved work space.Described scrambler 4 is installed on the carrying roller 8, and described carrying roller 8 drives its rotation by steel pipe, drives carrying roller 8 rotations along with steel pipe forwards, and realizes the synchronous operation of scrambler 4 and carrying roller 8, steel pipe.
Referring to Fig. 3, the integrated circuit figure of control module 5, first sensor 1, second sensor 2, the 3rd sensor 3, scrambler 4 is described in detail as follows:
1, whether need to survey long the selection by switch SA1, as needs, Closing Switch SA1 then, PLC input point I0.3 state is 1;
2, press the button SB1 after, PLC input point I0.4 state is 1, then PLC output point Q0.1 work, the production line roller-way begins just to change, and drives steel pipe and advances;
3, when steel pipe arrives 1# optoelectronic switch position, SP1 work, PLC input point I0.6 state is 1;
4, when steel pipe arrives 2# optoelectronic switch position, SP2 work, PLC input point I0.7 state is 1;
5, as I0.3, I0.6, when the I0.7 state is 1, PLC output point Q0.0 work, test carrying roller 8 rises, and drives carrying roller 8 servo-actuateds by steel pipe, scrambler 4 is along with carrying roller 8 rotations simultaneously.PLC input point I0.0, I0.1, I0.2 all have the pulse signal input;
6, when steel pipe arrives 3# optoelectronic switch position, SP3 work, PLC input point I1.0 works, and begins to read the pulse signal of I0.0, I0.1, three input points of I0.2;
7, when steel pipe left the 1# optoelectronic switch, SP1 resetted, and then PLC input point I0.6 state is 0, stopped to read the pulse signal of I0.0, I0.1, I0.2 simultaneously;
8, the pulse signal sum S of PLC by reading, divided by scrambler 4 umber of pulse C1 weekly, then can calculate the rotating cycle of scrambler 4, multiply by the girth C2 of carrying roller 8 then, can calculate the length of the part of detecting of steel pipe, add the regular length L2 between first to the 3rd optoelectronic switch, just can draw the physical length L1 of steel pipe.
L1=S/C1 * C2+L2 (the utility model length-measuring meter is calculated formula)
The technological process of production is: steel pipe transmission, first sensor 1 received signal, second sensor, 2 received signals, carrying roller 8 and on scrambler 4 rises, the 3rd sensor 3 received signals, carrying roller 8 wheel measuring length, first sensor 1 blackout, carrying roller 8 declines, data storage, data output to master control computer 6.Steel pipe transmits on roller-way, and when being sent to first sensor 1, first sensor 1 received signal also transmits signals to control module 5, and tested steel pipe enters test zone; Steel pipe continues to forward after entering the test section, when being sent to second sensor 2, second sensor, 2 received signals also transmit signals to control module 5, the carrying roller 8 of lifting and on scrambler 4 rise, rotate with steel pipe, before steel pipe arrives the 3rd sensor 3, make the steel pipe operation be in steady state (SS); When being sent to the 3rd sensor 3, the 3rd sensor 3 received signals also transmit signals to control module 5, and steel pipe is surveyed the farm labourer and begun, and the rotation girth of scrambler 4 will be recorded this moment; After steel pipe all passed through first sensor 1, first sensor 1 blackout stopped to survey length, and behind the time-delay 1S, the carrying roller 8 of lifting descends, and surveys the farm labourer and finishes.
Increase the long control system of survey on the roller-way existing production, survey long control system and adopt photoelectric sensor+scrambler 4+ control module 5 (PLC)+master control computer 6+ printers 7, the online dynamic survey of whole system precision-fit realization steel pipe is long.Measure by control module 5 (PLC) control testing length, PLC adopts Siemens S7-200 model, we are in about long 3 meters transfer roller zone, set three test points (A, B, C), in each test point photoelectric sensor is installed, the carrying roller 8 of VTOL (vertical take off and landing) is installed between A, B point then, and scrambler 4 is fixed on the carrying roller 8, rotates synchronously with carrying roller 8.Because in the steel pipe motion process, we make steel pipe by synchronous device movement velocity and carrying roller 8 and on the movement velocity of scrambler 4 consistent, rotation girth by measuring and calculating scrambler 4, movement length that just can the accurate Calculation steel pipe, by adding the distance between the fixing AC point, can accurately calculate steel pipe length again.All information relevant with steel pipe all are presented on the electronic curtain in real time, and screen divides two every trades to show, first row shows steel pipe information, and second row shows steel pipe length.Simultaneously, can realize the printout of data by the printer 7 that links to each other with the digital terminal display system.
Great advantage of the present utility model is to realize that the online dynamic survey of steel pipe is long, not newly-increased any station, but on original roller-way basis, set up the utility model, saved work space.Whole process is all accurately controlled by single-chip microcomputer, has reduced staff labor intensity, has saved cost of labor, improved work efficiency, avoid the measuring error that causes because of human factor simultaneously, improved measuring accuracy greatly, brought very big help for the production development of company.
By the foregoing description, the purpose of this utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top embodiment.Any modification that does not depart from function of the present utility model and structural principle all will be included in the scope of claims.
