The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail: a kind of heat is sent roller-way goods dynamic weigher, is made of weighing table, sensor and computer, it is characterized in that:
The roller-way of weighing table adopts and flexibly connects, and between LOAD CELLS and weighing table damping device is installed, and weighing table is equipped with stop, and the bottom installs counterweight additional, and LOAD CELLS is positioned at the weighing table both sides, is distributed in the piston type damping device;
Sensor comprises LOAD CELLS, photoelectric sensor and temperature probe, and the LOAD CELLS output links to each other with the analog signal amplifier input, and analog signal amplifier output connection mode number converter and computer connect and compose data and transmit the loop; Photoelectric sensor links to each other with computer by data acquisition and interface module and constitutes control loop; Temperature probe connects and composes data by data acquisition and interface module and computer and transmits the loop.
The operation principle of each several part is as follows among Fig. 1.When the steel billet of being weighed during from the weighing table of a certain direction by connecting into through flexible connecting device (1), LOAD CELLS output changes continuously with different generation the in the position of steel billet on table top, the position that photoelectric sensor (4) is installed because of selection is appropriate, when the steel billet head touches photoelectric sensor, this moment, steel billet all was positioned on the weighing table, after microcomputer collects this signal, control software begins to gather weight data, handle through software filtering, filter improper weight according to the steel billet bound threshold values of setting, adopt method of successive comparison to reject the data that indivedual fluctuations reach then, adopt ordinary numbers averaging method or weighted mean method to carry out data at last and handle, obtain the weight of this steel billet; When carrying out the weight signal collection, carry out selection of temperature signal through temperature probe (5), data processing method is identical with the weight data processing method, draws the testee temperature; Two each data are deposited in the database, and a counter is progressively increased, and show weight, temperature, number information simultaneously on display, print measurement ticket.When photo-sensor signal will is overturn again, tell scale under this steel billet of microcomputer, prepare next steel billet of weighing.
Sensor comprises following architectural feature: LOAD CELLS (A), photoelectric sensor (B), temperature probe (C) are installed in the roller-way side, by the analog signal of LOAD CELLS output through the amplifier input analog-to-digital converter after interface is sent into computer (D), detect the position of steel billet on the roller-way by photoelectric sensor, and positional information is imported into the computer control system co-ordination by data acquisition and interface module in real time; Temperature signal imports computer into by data acquisition and interface module after the temperature probe conversion, together deposit in the database with weight signal, characterizes the information of this steel billet; At last the data that collect are analyzed, calculated, by the weight of the alleged article of display (E) demonstration, by printer (F) output metering list and daily sheet by computer.
The installation site of photoelectric sensor is selected in 2 meters distant places of routine roller-way, prevents the infringement that steel billet high temperature that heat is sent causes photoelectric sensor, and the photoelectric tube transmitting range is as the criterion to detect the roller-way outward flange, in order to avoid the misoperation of weighing that roller-way outside personnel walk about and cause.Output signal connects the normally closed node of photoelectric tube, and when no steel billet passed through, microcomputer received high level and is shown as 1, and when steel billet passed through, photoelectric tube was off-state, and microcomputer receives low level and is shown as 0.At least should keep 3 meters spacing between the steel billet, in order to avoid preceding the also incomplete following table of steel billet then props up the misalignment of weighing that steel billet has begun to weigh and caused.
The installation site of temperature probe should be apart from 3 meters distant places, roller-way center, prevent that heat from sending the injury of steel billet high temperature to probe, and point for measuring temperature should be aimed at the steel billet axis, guarantees that thermometric is accurate.
It is in order to adapt to on-site actual situations that LOAD CELLS is located at the roller-way both sides, improve the LOAD CELLS position, be for reducing the weighing table center of gravity as much as possible, the vibrations that when passing through weighing table the roller-way bump produced for reducing the invar base, eliminate the influence of roller-way vibrations to measuring accuracy, except necessary stopping means (2), buffer unit (3) are installed, bottom at weighing table installs suitable counterweight uniformly additional, this measure has promptly reduced the center of gravity of weighing table, increase the stability of system again, improved measuring accuracy.
See Fig. 5 as adopting the flexible connection mode overlap joint between two groups of roller-ways of weighing table, wherein be designed to a slotted hole (6) in the junction, it can discharge the longitudinal deformation that roller-way produces because of variations in temperature, thereby make LOAD CELLS under which kind of temperature, can not guarantee the stability of weighing because of table top deformation produces stressed variation.Be designed to axle in the middle of the roller-way and connect (7), between two groups of roller-ways as weighing table relative motion can take place, both can adjust the levelness of sensor between table top easily, can cushion the vibrations of roller-way so again, two groups of roller-ways are coordinated to increase the stability of system in the middle of a plane.
For increasing the stability of system, also to design the piston type damping device and seen Fig. 7, it is divided into two parts up and down, fills yielding rubber (9) at damping push-down head (10), and damping seaming chuck (8) inserts damping push-down head (10) the inside during use.This design had both absorbed the roller-way vibrations, had guaranteed the trouble free service of sensor again, even the stressed crooked situation of sensor can not take place the aging fracture of yielding rubber yet; In addition, at damping push-down head (10) design one circular hole (11), make when changing yielding rubber convenient.
The integrated stopping means of omnidirectional is seen Fig. 8,9,10, is designed to be positioned on the mainboard to spacing in length and breadth, can carry out the adjustment of longitudinal and transverse two directions easily when needing, and has made things convenient for maintenance, sets up the idea that the overall situation is adjusted.Make in the design base and body portion from, make stop in height can freely adjust, to adapt to different needs.
For the line of photoelectric sensor, temperature probe and computer is seen Figure 11, photoelectric sensor (G) is automatic in service the playing an important role of coherent system, output signal connects the normally closed node of photoelectric tube, after digital data acquisition module (H) is gathered, with the transmission of RS485 communications protocol, the RS485 communications protocol can be carried out network easily and be connected, and transmission range is far away, antijamming capability is strong, meets the site environment requirement.The RS485 communications protocol is sent into microcomputer (L) and is handled after interface module (K) is converted to the RS232 communications protocol, when no steel billet passed through, microcomputer received high level and is shown as 1, and when steel billet passed through, photoelectric tube was off-state, and microcomputer receives low level and is shown as 0.Microcomputer is controlled whole system operation against the different output state of photoelectric sensor just.The analog signal of temperature probe (I) output is incorporated the RS485 communication network of photoelectric sensor into after Analog Data Acquistion Module (J) is converted to the RS485 communications protocol, send into MICROCOMPUTER PROCESSING be converted to the RS232 communications protocol by interface module (K) after transmitting after.Microcomputer obtains this two-way unlike signal by time-division processing.
