Description
Technical field
The utility model relates to a kind of elevator system using Bar code positioning at car production travel line, belongs to conveyer control technology field.
Background technology
Elevator is a kind of equipment common in car production travel line.It is elevated auto body and automotive parts as required, and the horizontal load transfer device of cooperation is delivered to vehicle body and part the travel line of differing heights.
Usually, every platform elevator is all provided with one and sends out number block, be elevated with elevator, the column of elevator is equipped with multiple sensor, when certain sensor sensing is to sending out a number block, just can obtain current lifting position signal, when these signals pass to after PLC (programmable logic controller (PLC)) processes, according to result, elevator continues to run, slow down or stop.
But along with the development of car production travel line, the continuous quickening of productive temp, accuracy requirement is more and more higher, and elevator also constantly changes, and the position that elevator stops is increased, and the distance between position is more and more less.So just make sensor get more and more, the distance between sensor is more and more less.Number of sensors increase, makes sensor be failure to actuate or the probability of misoperation increases, and causes elevator malfunctions rate to increase.The spacing of sensor diminishes, and causes sensor to install difficulty, even cannot install.
Summary of the invention
The purpose of this utility model is for above-mentioned existing problems, to propose a kind of elevator system of Bar code positioning, Bar code positioning systematic difference, can automatically control elevator carry out complicated lifting action according to production requirement.
According to the technical scheme that the utility model uses, the elevator system of described use Bar code positioning comprises elevator and elevator control system, described elevator comprises: column, jacking system and horizontal transferring device, jacking system is along column up-down under the driving of lifting motor, and horizontal transferring device is delivered to vehicle body and part in elevator or from elevator and pulls out; Vertically bar code is laid at the side of described column, bar-code reader installed by jacking system, and the signal output part of described bar-code reader is connected to elevator control system, and bar-code reader is with jacking system one lifting, and the location information read in bar code, send to elevator control system.
Described bar code continuous print is laid in the whole process that jacking system runs.
Concrete, described elevator control system adopts PLC, and described bar-code reader is connected to PLC by fieldbus, or described bar-code reader is connected to interface module, then is connected to PLC by fieldbus.
Concrete, the distance between described bar-code reader and bar code is 80 ~ 120 millimeters.
Concrete, described bar code covers layer of transparent protective cover, as the organism glass of 1 to 3 millimeters thick.
The utility model has the advantages that:
1, save a large amount of detector switches: because the utility model adopts Bar code positioning system, the former sensor for detecting lifting position and a number block can be cancelled.
2, lifting distance is long: the length of bar code can reach ten thousand metres.
3, precision is high: the survey precision of Bar code positioning system can reach within 1 millimeter, detects many accurately than sensor.
4, communication modes is many: bar-code reader carries Ethernet, RS485, RS232, SSI and Canopen multiple interfaces, and energy and most of PLC carry out Direct Communication; If by interface module, the location information that bar-code reader reads can be converted to the receptible signal of various fieldbus, by fieldbus, signal be sent to PLC.
Accompanying drawing explanation
Fig. 1 is with the elevator system schematic diagram of Bar code positioning.
Fig. 2 is Bar code positioning system electrical structural representation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The utility model lifting position of Bar code positioning systematic survey elevator, to reach the accuracy ensureing lifting position and the object of carrying out stall falling guard.
Elevator system comprises elevator, elevator control system.Wherein, as shown in Figure 1, elevator comprises: column 14, jacking system 7, horizontal transferring device, can also comprise auxiliary shifting apparatus.Column 14, as the track of movement in vertical direction, ensures the straightness accuracy that jacking system 7 moves.Jacking system 7 is with vehicle body 13 and part lifting under the driving of lifting motor 6, and vehicle body 13 and part are transported to different height.Horizontal transferring device (comprising ground level feedway 8 and aerial horizontal transferring device 9) is delivered to vehicle body 13 and part in elevator, or vehicle body 13 and part are pulled out from elevator.Aerial horizontal transferring device 9 by the air can folding suspender 11(suspender 11 both sides be suspender open-and-close mechanism 12) delivery vehicle body 13 and part, ground level feedway 8 delivers vehicle body 13 and part by ground chassis 10.Auxiliary shifting apparatus is the interference in order to avoid in lifting process between equipment, and prevents vehicle body and part from offseting in transfer process.
The utility model installs bar-code reader 1 on jacking system 7, and the signal output part of bar-code reader 1 is connected to elevator control system, and the location information on the bar code reading 2 that bar-code reader 1 is real-time, sends to elevator control system.General elevator control system adopts PLC.Bar code 2 continuous print is laid in the whole process that jacking system 7 runs.
Bar code positioning system as shown in Figure 2, comprises bar-code reader 1, bar code 2 and fabricated section.Bar-code reader 1 is arranged on the jacking system 7 of elevator, with jacking system 7 one lifting, and reads the location information in bar code 2, sends to PLC 5 or interface module 3 by fieldbus 4.Bar code 2 is arranged on column 14 side of elevator, and the distance between bar-code reader 1 and bar code 2 is 80 ~ 120 millimeters (adopting 100 millimeter in embodiment).If when environment is more severe, layer of transparent protective cover can be covered in bar code 2, such as the transparent organic glass of 1 to 3 millimeters thick, prevent bar code contaminated.Fabricated section is used for fixing bar-code reader 1 and bar code 2.
The elevator control system of Fig. 2 comprises PLC 5 and interface module 3.If PLC 5 can directly and bar-code reader 1 communication, then without the need to interface module 3; Otherwise usable interface module 3 converts the receptible signal of various fieldbuss 4 to the location information that bar-code reader 1 reads, and by fieldbus 4, signal is sent to PLC 5.PLC 5 processes according to these signals, controls adjustable height and the rising or falling speed of elevator, when elevator falls, controls lifting motor 6 at once and carries out emergency braking.
Because bar code have employed the form of continuous programming code, PLC can be made to know the particular location of lifting exactly, and the fault caused by sensor misoperation will no longer exist.And calculated by PLC, can rising or falling speed be obtained, when elevator falls, lifting motor can be controlled at once and carry out emergency braking.
In a word, elevator adopts Bar code positioning system, make the location information Real-time Feedback of elevator to PLC, not only save the quantity of sensor and contact block, also improve the reliability of equipment.
