Description
(1) technical field: the utility model relates to the logistics transhipment conveying equipment in the industrial production line, especially a kind of continuous intelligence automatic carriage transport control system.
(2) background technology: automatic carriage is the common equipment of logistics transhipment pipeline, it is to contact in mobile and carry out power taking by current-collector being installed on the car body and being contained in trolley in the track in advance, offer mobile dolly, this way to take power has been a proven technique very, and to carry out data communication be comparison difficulty and special but contact with current-collector by trolley.The one, because trolley is parallel lay-up in orbit, and distance is closer, between insulation is only arranged, the line body exposes and does not have the protection of screen layer, there is very big impedance between trolley and the current-collector sliding contact, and the effect that contacts in the sliding process is also unstable, exists and disturbs and various labile factor.The 2nd, the communication data quality problems, because the limitation of each side such as the requirement of the size of track and trolley, installation and economic target, the quantity of trolley is used a lot.Tradition automatic carriage control mode is to adopt the trolley fragmentation technique, this control mode is the vehicle-mounted PLC mode of posting a letter of arriving at a station, the walking power supply of dolly and control, lifting power supply and control etc. all rely on the trolley unit, therefore the number of poles of trolley is a lot, basically all 6 extremely more than, will reach 10 utmost points in the time of maximum, under the operating mode of some technological action complexity, this control mode can not meet the demands.Because dolly control action depends on mobile current-collector collection, the failure rate of system is than higher.Simultaneously, because dolly must stop at each technology station and carry out PROCESS FOR TREATMENT, such as the lifting action of workpiece, rocking action or the like, the operation of system is step, influenced the efficient of equipment, this method of operation satisfies technological requirement in traditional automobile making technology and engineering machinery worker artistic skill.Along with the improvement of manufacturing process, auto manufacturing and engineering machinery manufacturing industry are had higher requirement to automatic carriage, and this is more complicated comprising technological action, the efficient of equipment is higher, the reliability of system, flexible better.Obviously, traditional automatic carriage can not satisfy these requirements.
(3) summary of the invention: it is periodic running that the purpose of this utility model will solve traditional automatic carriage control mode exactly, efficient is low, the number of poles of trolley is limited, range of control is restricted, the problem that system reliability and control accuracy are lower provides a kind of continuous intelligence automatic carriage transport control system
Mentality of designing of the present utility model is: use ripe wireless industrial Ethernet control technology, the trolley segmentation control mode that replaces traditional automatic carriage, the current collection unit only provides power supply to dolly, and no longer bear the message exchange task, the message exchange of dolly and ground main control PLC relies on wireless ethernet to finish.
Concrete scheme of the present utility model is: design has ground master control set and n dolly unit and assists the trolley of establishing along track, trolley is given by contactor respectively, provide power supply by current-collector for the dolly unit again, it is characterized in that: the described ground of a. master control set includes main control PLC, PLC control linkage ethernet module and contactor, and being connected with push-button station, described ethernet module is connected with switch and WAP in turn; B. described dolly unit includes CPU element, is connected with wireless client, sensor, detector switch and walking frequency converter and A.C. contactor respectively with CPU element, and is fitted with reflecting plate in the dolly unit.
Sensor in the dolly described in the utility model unit and reflecting plate are installed in the front and back end of dolly respectively, keep the wherein sensor of a dolly and the reflecting plate positioned opposite of adjacent another dolly.
The power supply of native system dolly moves power supply technique by the trolley of maturation and provides.System is tied the CPU element on ground main control PLC and the dolly by wireless ethernet and does as a wholely, and CPU controls the executive component on the dolly again, as the walking frequency converter of control carriage walking, the contactor that the lifting of control cucurbit is used etc.
The native system control mode is separated power supply and control, and train of thought is clear, and function distinguishing is clear and definite, has improved the reliability of system; Reduce the quantity of trolley, saved cost; Simultaneously the amount of information exchange of wireless industrial Ethernet is big, and or else the control of dolly be subjected to the restriction of trolley quantity, system with better function.
Because dolly for connecting the through type operational mode, for solving crashproof problem between the dolly, adopts intelligence sensor, can change the long-pending distance of putting of dolly in the native system according to the difference of technology.Intelligence sensor is by two positions of self study mode initialization, and corresponding these two position signallings have two switch outputs.Its self study pattern can flexiblely change to amass puts distance, in case product remodeling does not need to change hardware, its detector switch output signal can make dolly different in the long-pending distance of putting of skill section and laying section.Dolly has workpiece on the suspender when process section, Workpiece length is often long than dolly group, and the long-pending dolly of putting on the return phase is not to be with workpiece, at this moment in order to save the space, to improve the factory building utilization factor, requires the long-pending distance of putting of dolly to shorten.The benefit that adopts the smart distance sensor is that intelligent carriage can it be in PROCESS FOR TREATMENT section or the long-pending return phase of putting by the differentiation of external detection element, can change by interlocking and detect distance.The long-pending mode of putting of traditional machinery is in the length that prolongs the dolly group, at the head of dolly crashproof travel switch is housed, and at afterbody impulse sender is housed.Because the length of dolly group is elongated, certainly will increase machine cost, in case workpiece is retrofited simultaneously, the length of dolly group must change thereupon, and this has also increased cost for later stage product remodeling.Compare with long-pending the putting of traditional machinery, adopt the smart distance sensor, system flexibility is higher, in case product remodeling, do not need to change mechanical suspender, just can realize long-pending playing function by adjusting the long-pending distance of putting, simultaneously, because the long-pending distance of putting of return phase can be dwindled by sensor, therefore, identical line body length, return phase free parking car more can be improved the factory building utilization factor.
The advantage of native system is:
1. continuously-running work, the efficient height;
2. safe and reliable to operation, the operating accuracy height;
3. broad covered area, frequency height are not subject to disturb, and power is low to be not easy to disturb other equipment;
4. can adapt to the comparison rugged environment;
5. easy for installation, construction is fast, exempts a large amount of rigid line constructions;
6. application interface is open, and high maintenance is convenient;
7. expansion is easy, the flexible degree height;
8. the exchanges data amount is big, and speed is fast.
