The specific embodiment
The present invention is based on the friction type conveying machine control system of fieldbus, and the PLC of main website connects supervisory control computer by the Ethernet net, and adopts man-machine interface to do on-site supervision.
Its structure is to comprise delivery system 1, control system 2 and output system 3, and they link together by fieldbus and Ethernet.Wherein:
Delivery system 1 comprises friction type conveying machine, stopper, track switch, elevator and a plurality of detecting unit that is used for the workpiece conveying.Friction type conveying machine is the main body of whole travel line, is installed on the track; Stopper also is installed on the track, can stop workpiece, and when it was opened, the friction type conveying machine before the stopper could move; Track switch being used to adjusted the turnover order of workpiece or pulls out the workpiece maintenance, has only when track switch is got to straight way or bend fully, and the friction type conveying machine before the track switch could move; The workpiece that elevator is used between the different travel lines is reprinted, and on the elevator inner orbit friction type conveying machine is housed, and workpiece is sent in the elevator; Detecting unit is installed on the suspender or chassis of supporting workpiece, touches the switch that is installed on the track by detecting unit, sends signal to control system, friction type conveying machine is started and stops.
Delivery system also comprises the CPC chain, and the beat of CPC chain can be adjusted, and is used for the manual work station more; Be used for pinpoint registration device; Be used for side top machine, the transfer machine used when workpiece moves, friction type conveying machine is delivered to the chassis that workpiece is housed in the machine of side top, and the upper frame of side top machine rises, hold up workpiece, telescopic fork on the transfer machine stretches out, and the upper frame of side top machine descends, and workpiece drops on telescopic fork withdrawal in back on the telescopic fork, transfer machine band workpiece telescopic fork after machine operation in opposite side top puts in place oppositely stretches out, the upper frame of opposite side top machine rises, and holds up workpiece, the telescopic fork withdrawal, the upper frame of side top machine descends, and workpiece drops on another chassis.Number of devices is many, has the dispersiveness of height, and it is many that this causes I/O to count, and control path is long, must adopt field bus control system.
Output system comprises indicator lamp, electromagnetic valve, and indicator lamp is positioned on the execute-in-place box, shows the mode of operation of local travel line, and electromagnetic valve is positioned on the on-the-spot pneumatic element.The PLC of main website is connected with computing machine on the EtherNet, uses running state, operational factor, the automatic fault that configuration software can show each production facilities and report to the police, the record trouble point accesses relevant control program, and can stipulate the come in and go out order of storage area of workpiece.
Friction type conveying machine system, be usually used in the storage and the ordering of workpiece, the task of travel line is exactly that workpiece is shifted to position B according to people's requirement from position A, friction type conveying machine as main body, manner of execution is simple, only needs conveying work pieces to get final product, and other function (as: location, transfer, ordering etc.) is to be realized by miscellaneous equipment, realize the equipment of the same type often of said function, rely on control to realize the function that parameter is different so the device type of whole production line is limited.In this design process with the workpiece storage friction type conveying machine system is example (this part comprises several representative type load transfer devices), illustrates how control task realizes by Fieldbus Based control system.
The task of friction type conveying machine system be exactly workpiece according to people's requirement from elevator A, sort by the workpiece type by the workpiece storage district, remove from elevator B successively on request at last, as shown in Figure 1.
Each workpiece all has a read-write year sign indicating number body, has write down the information (as: color, type, numbering etc.) of workpiece.Gangway in elevator A and workpiece storage district, recognition system all is housed, the recognition system of elevator A can write the information of workpiece and carry in the sign indicating number body, the recognition system of gangway, workpiece storage district, can the sign indicating number body that carries on the workpiece be scanned, and information passed to PLC by fieldbus, PLC (this requirement can also can be stipulated by man-machine interface by computing machine, can be changed at any time) as requested controls the order of the discrepancy storage area of workpiece.
Contrast Fig. 2, friction type conveying machine is installed in orbit, and group more than being divided in order, every group can have one or more friction type conveying machines, every group of friction type conveying machine established a control capsule, control the starting of this group friction type conveying machine and stop, each friction type conveying machine is other all to have a photoelectric switch to be used for detecting whether workpiece is arranged herein, and signal is imported in substation of this group friction type conveying machine control capsule; Track switch need be established straight way, bend, be gone out the track switch detector switch; Stopper need be established occupy-place, beginning, closed end, reset detection switch; elevator need be established and put in place, the deceleration that puts in place, rises down, descend to slow down, rise spacing, descend spacing and chain rupture protection detector switch, the high-revolving effect of buffering is generally all played in the use of deceleration point.The elevator side of floor also need be arranged the check point that the operating personnel invades about connecting, and takes place with accident prevention.
Computing machine, PLC carry out the information translation transmission by each detecting unit in each substation and the delivery system.Between computing machine and the fieldbus being can not be direct coupled, on-the-spot detector switch distributes and disperses very much, and the informational needs of these check points is input to the PLC that is arranged in control housing, the fieldbus mode is equivalent to input and output (I/O) module has been put into each on-the-spot corner, each check point can closely be delivered to load module to signal, and the output signal of needs such as indicator lamp and electromagnetic valve also can obtain from output module nearby; And can on-the-spot control module be that core is formed control loop nearby friction type conveying machine is controlled, have significantly reduced control loop and on-the-spot wiring in the control housing.
The topological structure of fieldbus employing is a line style as seen from Figure 2, and in fact fieldbus can also select star-like or the tree type, and the adoptable topological structure of different fieldbuss also is different.
