Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, present embodiment is being to implement under the prerequisite with technical scheme of the present invention, should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention.
Like Fig. 1, shown in Figure 2; A kind of bulk density on-line intelligence pick-up unit; Comprise sampling apparatus 1, communication is connected to electrical control cabinet 2 and controller 3 on sampling apparatus 1, joins through communication cable 13 between sampling apparatus 1 and the controller 3; Electrical control cabinet 2 joins through data conversion module 4 with controller 3, on sky direct 3, also is connected to printer 12; Wherein sampling apparatus comprise charging reload the bucket 5; Charging reload bucket 5 tiltedly below reverse mechanism 6 is housed on the headwall; Charging reload bucket 5 below be provided with graduated cylinder support 7 and electronic scales 8, reloading in charging is provided with scraping mechanism 9 between bucket 5 and the graduated cylinder support 7, and discharge mechanism 10 is housed below graduated cylinder support 7; On discharge mechanism 10, be provided with fan 14, below discharge mechanism 10, be provided with receiving hopper 11.Reload bucket, scraping mechanism and discharge mechanism of above-mentioned charging all adopts pneumatic mode.
Bulk density on-line intelligence pick-up unit is made up of scene material grain harvester (being sampling apparatus), electric control system and computer supervisory control system three parts.On-the-spot material grain harvester is the core of this system, and its effect is to utilize mechanical mechanism regularly to collect the material grain from production line, and with weighing after the material grain metering of collecting, the material grain after will weighing is at last discharged on-the-spot material grain harvester.The main effect of electric control system is that mechanical actuating mechanism is controlled by instruction, so that material grain harvester is operated by specified action.Computer supervisory control system mainly is that the weighing measurement signal is gathered, and the data that collect are handled and analyzed.Bulk density on-line intelligence pick-up unit structural principle block diagram is as shown in Figure 3.
Each major part principle of work and power of the present invention is following:
Reverse mechanism: during the production line operate as normal, material grain is got into by a material grain acquisition system top fed bucket, is emitted by artificial discharging opening, and when automatic collection material grain, refueling agency is carried out action.
Refueling agency (charging reload bucket): adopt minitype cylinder, the cylinder front end connects reverse mechanism, drives the reverse mechanism switching-over during cylinder action.Realize the online acquisition of material grain thus.This mechanism utilizes minitype cylinder to make the switching-over of switching-over bucket, utilizes spring reset, and is simple in structure, compact, is to realize automatically feed better mode.
Scraping mechanism: after the material grain gets in the graduated cylinder, in order to realize accurate measurement, just need utilize scraping mechanism that the material grain at graduated cylinder top is wipeed off, scraping mechanism is that the minitype cylinder front end connects scraper plate.This mechanism utilizes minitype cylinder as executive component, and structure is small and exquisite, is convenient to be installed on device inside, is the better mode that realizes scraping automatically material.
Discharge mechanism: after utilizing the electronic scales weighing, just need utilize discharge mechanism that the material grain in the graduated cylinder is drained, discharge mechanism is that the minitype cylinder front end connects panel turnover mechanism, utilizes panel turnover mechanism that the material grain is drained.
Weighing mechanism: the weighing mechanism core component is an electronic scales, utilizes support that graduated cylinder is fixed on the table top of electronic scales.The weight of electronic scales weighing is the gross weight of support and graduated cylinder, material grain.Data are removed the weight of support and graduated cylinder after electronic scales is handled, the data that send computing machine to are the weight of material grain.
Control system: among the present invention; Computing machine (controller) plays core and leading position; The effect of data conversion module in this control system is acquisition elements and executive component; It is responsible for becoming digital signal to pass to computing machine the conversion of signals at scene, utilizes the on-the-spot element of Data Control after the Computer Processing again.Itself is not with intelligent parts the I/O module, and it is uploading and following biography of responsible data only, accomplishes programme controlled task by computing machine.
The host computer programming software is then passed to computing machine with the reading of electronic scale through the operation of switch, scraping mechanism and the discharge mechanism of each pneumatic valve of I/O module controls, through software the electronic scales data is carried out analytical calculation, generates the density of material.Through system simulation figure dynamic display device duty, each data generates sampling analysis data sheet and alarm logging simultaneously simultaneously, and deposits data in database, so that inquiry in the future.
This system on Windows 2000 software platforms, utilization design idea of oriented object (OOP), based on the exploitation down of the environment of SQL network data base, advanced design, stable, conversion accuracy is high.Because this The software adopted SQL Server database, it has data processing function, can access historical data arbitrarily according to user's requirement with various form store data.On data structure and storage method of calling is that any other configuration software is incomparable.
This system has extendability, and system adopts network-type SQL SERVER database, and the computing machine that can supply to be in the consolidated network is shared use.Database section and the separate operation of system monitoring part.Wherein use the SOCKET pattern to carry out exchanges data, so, as long as any client computer in same LAN is installed the surveillance part, can realize real time monitoring and the inquiry of historical data function.
