Description

Industrial roller quickly conveys the control flow of carton
Technical field
The present invention relates to carton conveying technology fields, and in particular to a kind of industry roller quickly conveys the control stream of carton Journey.
Background technique
With the rapid development of industry, unmanned factory is realized.The product of plant produced needs remote quickly conveying, To realize the connection of workshop and storehouse, efficient, the orderly conveying products of factory's needs.
Normal control mode is that the conveying of carton is realized by the control mode of occupy-place at present, can be because of every series cylinder Length and switch limitation, can not realize that high-volume chest keeps spacing and quick conveying without pause is run, it cannot be guaranteed that It is completely successional while starting operation.In order to which large batch of carton cargo guarantees the fastest transport, it has to increase actively The quantity of roller will increase a large amount of cost to reduce the distance of every series cylinder come the control transporting paper more refined in this way, meet Still it cannot achieve the effect that product in root when blocking up case to special circumstances while start conveying.
Summary of the invention
In order to solve the above-mentioned technical problem the deficiency in, it is an object of the invention to: it is quickly defeated to provide a kind of industrial roller The control flow of paper feeding case can be improved the speed of industrial medium and long distance conveying article, make delivered article on roller Minimum range and the orderly quick conveying without pause are kept, is not limited by single group drum length, according to the length of single group roller, Realize that single group roller orderly conveys the purpose of multiple products.
The present invention is technical solution used by solving its technical problem are as follows:
The industry roller quickly conveys the control flow of carton, comprising the following steps:
(1) it is transported using the start and stop that plc controller controls roller QB by way of detection switch IA, IB and IC are counted Row, when carton runs to IB to IC from roller IA detection, roller QB starting connects goods when the counting of IA is greater than the counting of IB, works as IB Counting be greater than IC counting when roller QB start delivery；
(2) prevent from preventing detection switch from accidentally interfering in special circumstances in transmission process by counting the method corrected, tool Body method is as follows:
A, three switch countings be it is opposite, chest must first pass through IA, using IB, finally pass through IC, the meter of IB Number certainly cannot be greater than IA, be greater than IA if there is IB, and the counting of IB subtracts 1, and the counting of IC cannot be greater than IB, IC occur and be greater than The counting of IB, IC subtract 1；
B calculates different counting errors according to the length of different roller QB, length, the length of carton according to roller QB Degree, carton distance computation go out a series cylinder and can transport the theoretic numerical value of carton, the counting of IA subtracts the counting of IB not The numerical value can be greater than, the counting that the counting of IB subtracts IC cannot be greater than the numerical value, reduce the tired of detection switch counting to reduce Error is counted, setting numerical value allowable error range is lower than the theoretic numerical value, if it exceeds setting numerical value, automatic calculate is corrected, That is count is incremented by IA, or the counting of IC subtracts 1；
C, if the case where special circumstances are tested with even case, the IA and IB of roller QB can add 1 automatically, guarantee among roller It will not cause the case where finally depositing case because counting few meter, the counting that IA or IB can only be occurred by counting is counted more, will not be counted less, to reach The possibility of case is deposited caused by roller will not being caused to stop because of counting error into roller QB operation, normal count does not have the case where error Bottom roll can automatic start-stop, if generating counting error, IA, IB, IC do not have a signal, and roller QB operation can be made automatically by time-out IA, IB, IC count equal, roller QB stopping；
(3) self diagnosis is counted in operational process；
(4) occur self adjusting when stifled case or even case under fortuitous event；It is specific as follows:
If: a normal carton is 1 second by the time of optoelectronic switch, when carton is continuously across the time T2 of optoelectronic switch When > 1.5 seconds, it is believed that be stifled case occur.
1, because functional block is to control the start and stop of roller QB, so the switch of only IB detects stifled case situation.When IB is examined Stifled case is measured, set intermediate variable M1 and M2, M1 disconnects the starting of B roller, while intermediate variable M2 disconnects self examining for counting Function is corrected in disconnected function and counting, exports error signal to upper previous series cylinder stop pin.Intermediate variable M1 timing simultaneously T3, the T3 time reset M1, make stifled case roller stepwise operation, and stepping period 2*T3 achievees the purpose that separate chest automatically.B switch Failing edge can also reset intermediate variable M2 to differentiate whether stifled case releases.If it is desired to the spacing between widening carton, Ke Yishi When the occupy-place time for extending inside power-off holding of the carton by switch IB, realized by stifled case control.
2, set intermediate variable TZ, intermediate variable when next series cylinder error signal, which passes to pin stop, signal TZ disconnects the operation of IB to IC (delivery), simultaneously switches off to count diagnostic function and count and corrects function.If IB has signal at this time In the case where, meeting set intermediate variable X, set intermediate variable tz12 after runing time T5, breaks when the counting that IA subtracts IB is greater than 1 The operation of roller IA to IB (connecing goods) is opened, (when roller deposits the case where carton number is 2, exporting error signal), (roller deposits case number When being 3, the counting of IA-IB resets set intermediate variable tz12f after variable tz12 roller operation delay T6, roller when being greater than 2 It is out of service, while error is exported to the stop pin of previous group.As long as roller meets error condition, stop is successively passed to Pin), achieving the effect that be open to traffic is arranged successively.
3, if stop pin has signal, and IA-IB is counted when depositing case number greater than roller, and roller QB can stop, also It is to deposit case and connect goods to transfinite, the stop position that prolonged failing edge controls the last one carton is prolonged by IA occupy-place switch, and it is upper One group of carton generates spacing.
After 4, stop signal cancellations, meeting automatic time delay starting time T7 starts roller, disconnects error output, is delayed simultaneously T5 and T6 can gradually successively decrease.The timing of T5, T6 change in 0 to setting time, so that the chest of sliver is reached linear and open Stop effect.Subsequent chest will not be caused to generate stifled case again because of stifled case Frequent Troubles.
5, when stifled case situation releases, functional block error signal can be cancelled automatically, while the stop input of latter series cylinder Pin is equal to 0, resets intermediate variable TZ by time T9, cancels tz12 or tz12f, run roller.The time of T9 is exactly The time difference that roller successively starts.Make spaced starting between roller and roller, reduce while starting roller starting current, protects Protect power supply.
6, the function that every roller has automatic identification to connect case, even if there is even case, from the identification to tail successively, meeting is certainly It is dynamic to separate.
Normally in the case where not stifled case, as long as there is carton, roller can be round-the-clock turn, when not having the pause of waiting Between.Only without carton or stifled case in the case where, roller can stop.As long as between the minimum for controlling the entrance carton of finished product conveying Away from the stacking rhythm in the conveying speed cooperation outlet warehouse that roller conveying can be most fast, centre is not in the case where connecting case.I.e. So that warehouse system is broken down, also can go out to pass out error signal and control finished product conveying entirety to roller input pin stop Movement schedule.
The design parameter of the length setting of the length and carton according to roller is needed inside program: case number is deposited on roller； Two chests connect the case testing time；The occupy-place that detection switch power-off in place is kept extends the time；Successively start the time between roller；It is stifled Case roller stepping period；Second case stifled case dwell time；Third case blocks up case dwell time；Roller runs time-out time.
The time timing mode of this program uses the cycle time timing of clock pulses, effectively controls the time with addition and subtraction Variation, the precision of time can achieve 1 millisecond.Reach high-precision and the independent of functional block uses.
Further preferably, self diagnosis, including following situations are counted in step (3) operational process:
A, if IA, IB, IC tri- switch all without signal, and IA, IB, IC tri- count all equal and counting and are greater than 1, three countings are primary without variation automatic clear more than three seconds；
B, if IA switch does not have signal, the counting of IA is greater than the counting of IB, reaches and connect goods time-out time, make the counting of IA Counting equal to IB；Or if IB switchs no signal, the counting of IB is greater than the counting of IC, is more than delivery period, makes IC's The counting for being equal to IB is counted, the stopping of roller QB time-out is reached；
C, if IA has signal, the counting of IA, IB are equal, and the counting of IA adds 1 automatically, if IB has the meter of signal IB, IC Number is equal, and the counting of IC, which subtracts 1., runs roller QB, corrects counting error；
D, when the counting of IA is equal to 32760, the counting of IA, IB, IC subtract 32760 respectively, most beyond a storage word Big value is reset；
E claps emergency stop when breaking down, if the counting of IA is equal to the counting of IB when reruning, count is incremented by IA, makes The delayed startup of roller QB from back to front successively, has prevented centre from having runout situation, and whether detection carton retains.
Compared with prior art, the invention has the following advantages:
1, the present invention can reduce production cost, reduce the quantity of drive roll, accomplish energy saving, reduce equipment consumption Material.
2, the present invention can reach most ideal most quick conveying, and large batch of carton can be continuous continual quickly defeated It send, adequately utilizes the acting of drive roll, so that the efficiency of roller conveying carton is reached maximum utilization, while carton can be kept Between minimum spacing.
3, quickly operation is reached orderly when having special status.Occur stifled case or it is objective deposit case after, subsequent roller can be with It is realized on every series cylinder and is uniformly distributed multiple cartons, and successively ordered arrangement.All cartons can open simultaneously after solution situation Dynamic conveying, improves efficiency.

Specific embodiment
The embodiment of the present invention is described further with reference to the accompanying drawing:
Embodiment 1
As shown in Figs 1-4, industrial roller of the present invention quickly conveys the control flow of carton, comprising the following steps:
(1) it is transported using the start and stop that plc controller controls roller QB by way of detection switch IA, IB and IC are counted Row, when carton runs to IB to IC from roller IA detection, roller QB starting connects goods when the counting of IA is greater than the counting of IB, works as IB Counting be greater than IC counting when roller QB start delivery；
(2) prevent from preventing detection switch from accidentally interfering in special circumstances in transmission process by counting the method corrected；
(3) self diagnosis is counted in operational process；
(4) occur self adjusting when stifled case or even case under fortuitous event.
1, according to the composed structure of Fig. 1 explanation function block, share 4 input pins, 1 output pin.Input pin point It is not A, the three-arrive-place switch and an alarm roller of B, C stop stop.Output pin is roller QB operation and calls interior There is output failure error inside portion data block DB.Functional block only one, every series cylinder has corresponding data block DB.Namely Start-stop per adjacent three-arrive-place switch control intermediate calender rolls, corresponding data variable are different.
2, control analysis according to the conveying that Fig. 3 carries out roller part: carton is transported to C from A, three series cylinders in functional block Location switch IA, IB, IC, which combine, controls the start-stop of roller QB.All drive rolls have corresponding functional block to control, Corresponding data are stored in inside corresponding block of background data DB.It is also assumed that the location switch IB of this group is next group of function The location switch IA of block is the location switch IC of upper one group of functional block.
3, the error signal of this group of functional block passes to the stop pin of one group of functional block, reaches between adjacent roller Control, is played up and down, Partial controll and what is integrally controlled combine, and plays sliver when there is unpredictable failure Information transmitting effect, reach the synchronization start-stop of all cartons transmission.Detection switch IA in place, IB, IC and roller operation QB letter It number is external input, the output signal of plc.
4, the purport thinking of control is by the movement of the form control roller of counting, when the counting of IA is greater than the counting of IB QB roller starts (connecing goods), or the QB roller starting (delivery) when counting the counting for being greater than IC of IB.
5, Fig. 2 analyses.C12 indicates that location switch IA subtracts the count difference of location switch IB；C23 indicates that location switch IB subtracts Go the count difference of location switch IC；
6, analyzed according to Fig. 3, the countings of three switches be it is opposite, chest must first pass through IA, using IB, using IC.So the counting of IB certainly cannot be greater than IA, be greater than IA if there is IB, the counting of IB subtracts 1, and similarly the counting of IC cannot be big In IB, there is IC greater than IB, the counting of IC subtracts 1.
7, it is such as two meter five according to every group of drum length, 0.5 meter of the length of carton, 0.33 meter of carton spacing calculating, this One series cylinder of sample can at most walk three chests.The counting that the counting that the counting of IA in this way subtracts IB cannot be greater than 3, IB subtracts IC Counting cannot be greater than 3.In order to reduce the cumulative errors of switch counts, setting allowable error range is 2, if it exceeds allowing Error range calculates correction automatically (count is incremented by IA, or the counting of IC subtracts 1).
8, if the case where the company's of being tested with case, the counter switch IA and IB of every series cylinder can add 1 automatically, guarantee in roller Between will not lead to the case where finally depositing case because counting few meter.The counting that IA or IB can only be occurred by counting is counted more, will not be counted less, thus Reach the possibility that case is deposited caused by roller will not being caused to stop because of counting error in roller operation.Normal count does not have the case where error Doffer can automatic start-stop, if generating counting error, switch IA, IB, IC do not have a signal, and roller automatically can make to hold by overtime It closes IA, IB, IC and counts equal, roller stopping.
9, if IA, IB, IC tri- switch all without signal, and IA, IB, IC tri- count all equal and counting and are greater than 1, three countings are primary without variation automatic clear more than three seconds.
10, if IA switch does not have signal, the counting of IA is greater than the counting of IB, reaches and connect goods time-out time, make the meter of IA Number is equal to the counting of IB；If IB switchs no signal, the counting of IB is greater than the counting of IC, is more than delivery period, makes the meter of IC Number is equal to the counting of IB, reaches the stopping of roller time-out.
11, if IA has signal, the counting of IA and IB are equal, and the counting of IA adds 1 automatically.If IB has signal IB's and IC Count equal, the counting of IC, which subtracts 1., runs roller, corrects counting error.
12, when the counting of IA is equal to 32760, the counting of IA, IB, IC subtract 32760 respectively.Most beyond a storage word Big value is reset.
13, emergency stop is clapped when breaking down, if the counting of IA is equal to the counting of IB when reruning, count is incremented by IA, makes The delayed startup of roller from back to front successively has prevented centre from having runout situation, detects roller.
14, when occurring needing specially treated when unpredictable stifled case connects case situation in operational process.Because functional block is only It is the start and stop for controlling roller B, so the switch of only IB detects stifled case situation.It is more than to connect case when location switch IB continuously has signal When the testing time, it was demonstrated that stifled case breaks down, then set intermediate variable M1 and M2, and M1 disconnects the starting of B roller, while M2 is disconnected It opens the self-diagnosing function of counting and counts and correct function, export error signal to latter series cylinder stop pin.Intermediate variable Timing T3, the T3 time resets M1 to M1 simultaneously, makes stifled case roller stepwise operation, and stepping period 2*T3 reaches automatic separately chest Purpose.The failing edge of IB switch can also reset M2, differentiate whether stifled case releases.It, can be with if it is desired to the spacing between widening carton A carton is appropriately extended by the inside occupy-place time of switch IB, is realized by stifled case control.
15, the set intermediate variable TZ when previous series cylinder error signal, which passes to pin stop, signal, TZ disconnect IB To the operation of IC (delivery), simultaneously switches off to count diagnostic function and count and correct function.In the case that if IB has signal at this time, It can set intermediate variable X, set intermediate variable tz12 after runing time T5, disconnection roller IA when the counting that IA subtracts IB is greater than 1 To the operation of IB (connecing goods), (when roller deposits the case where carton number is 2, exporting error signal), (roller deposits case number when being 3, IA- The counting of IB resets set intermediate variable tz12f after variable tz12 roller operation delay T6 when being greater than 2, roller is out of service, Error is exported to the stop pin of previous group simultaneously.As long as roller meets error condition, stop pin is successively passed to), it reaches To the effect being arranged successively that is open to traffic.
16, if stop pin has signal, and c12 is counted when depositing case number greater than roller, and roller QB can stop, that is, Depositing case and connecing goods transfinites, and prolongs the stop position that prolonged failing edge controls the last one carton by occupy-place switch, with upper one group Carton generate spacing.
After 17, stop signal cancellations, meeting automatic time delay starting time T7 starts roller, disconnects error output, is delayed simultaneously T5 and T6 can gradually successively decrease.The timing of T5, T6 change in 0 to setting time, so that the chest of sliver is reached linear and open Stop effect.Subsequent chest will not be caused to generate stifled case because of stifled case Frequent Troubles.
18, when stifled case situation releases, functional block error signal can be cancelled automatically, while the stop of a upper series cylinder is defeated Enter pin equal to 0, resets intermediate variable TZ by time T9, cancel tz12 or tz12f, run roller.The time of T9 is just It is the time difference that roller successively starts.Make spaced starting between roller and roller, reduce while starting roller starting current, Protect power supply.
19, the function that every roller has automatic identification to connect case, even if there is even case, from the identification to tail successively, meeting It is automatic to separate.
20, in the case where normally not stifled case, as long as there is carton, roller can be round-the-clock turn, does not have stopping for waiting Immediately between.Only without carton or stifled case in the case where, roller can stop.As long as between the entrance carton for controlling finished product conveying Away from the step for exporting stacking of working good, centre be not in even case the case where.Even if stacking or barcode scanning break down, also can Error signal is passed out out to roller input pin stop to control the whole progress of finished product conveying.
21, when there is stifled case situation, (white carton represents stifled case to the schematic diagram (Fig. 4) of whole multiple carton arrangement operations The chest stopped afterwards, green carton represent the chest conveyed, and the position ABCDEFG corresponds to the end of every group of drive roll Location switch).When the location switch of G roller detecting even case the case where, behind carton on roller ABCDEF can pass through It counts and delay is arranged successively automatically, after trouble shooting, roller it is same to reach carton by the starting of start-up study successively When convey.If the case where least significant end of production pipeline goes out existing case or conveys carton stopping not, on roller Carton can also run automatic regular arrangement by roller.
22, need to set specific parameter inside program according to the length of roller and the length of carton: roller deposit case number= 3；Even case testing time=1.2s；The occupy-place of location switch extends time=500ms；Successively start time=100ms between roller； Stifled case roller stepping period=1s；Second case stifled case dwell time=1.2s；Third case blocks up case dwell time=1,8s；Roller fortune Row time-out time=10s.
