As shown in Figure 1, a kind of feed Weighing system of the utility model is made up of feed weigher 1 and control system, and wherein control system comprises main frame and the load module that is connected with main frame, output module, can have a plurality of feed weighers 1 to be connected with this control system simultaneously.
Part in the frame of broken lines has been expressed the composition of feed weigher 1, it comprises feeding machine 11 and scale body 12, scale body 12 is suspended in the below of feeding machine 11 discharging openings by at least three lifting ropes 14, all be provided with pulling force sensor 13 and turnbuckle 141 on the every lifting rope 14, turnbuckle 141 can be regulated the height and the quality of balance of scale body.The weight that pulling force sensor 13 is used to detect scale body 12 and goes up material as measuring sensor, pulling force sensor 13 all is connected with a transducing signal digital collection device 15, and transducing signal digital collection device 15 is connected by digital signal line (current pulse signal) with above-mentioned load module.Transducing signal digital collection device 15 just is installed in the scene of weighing, can be the conversion of signals of pulling force sensor 13 digital signal, and adopt the current impulse mode to send load module to, can guarantee the reliability and the stability of sensor signal like this, anti-tampering ability is strengthened, the transmitting range of signal can reach 1000 meters, has strengthened the scope of application of control system.
In system shown in Figure 1, what one of them feed weigher 1 adopted is belt conveyer scale body 12, and what another feed weigher 1 adopted is Chain plate scales body 12 ', and Chain plate scales body 12 ' also adopts the mode of suspention to install.
In system shown in Figure 1, feeding machine 11 is the Electromagnetically vibrating feeding machine, Electromagnetically vibrating feeding machine 11 be suspended in other four lifting ropes 16 below, also be provided with turnbuckle on the lifting rope 16, can adjust the correct position or the inclination angle of Electromagnetically vibrating feeding machine 11.The top of feeding machine 11 belts also is provided with feed bin 17, is provided with gate 18 and receiving hopper 19 below the feed bin 17.Feed under the situation that Electromagnetically vibrating feeding machine 11 is applicable at material particles 0.3～30mm, drying is inviscid and flow is little.Drop between the discharging opening of Electromagnetically vibrating feeding machine 11 or belt feeder 11 ' and below scale body is about 20～100mm, and scale body belt speed is second 0.08M/ second～0.5M/.
In system shown in Figure 2, feeding machine 11 ' is the belt-type feeding machine, belt-type feeding machine 11 ' be installed in feed bin 17 below.Adopt belt-type feeding machine feed, can strengthen feed gap dimension, widen the lengthening belt, flow range is extended to 300T/H, much larger than the Electromagnetically vibrating feed.If material is thin, moisture is big, when flow is big, be fit to adopt belt-type feeding machine feed.
Above-mentioned feeding machine 11,11 ' drive motor are connected with the output module of control system, and control system can be controlled the operation of feeding machine.
Below control method of the present utility model is described.
1. the mode that adopts the discontinuous blanking to weigh
As Fig. 3＜A〉shown in, when system start-up, measure earlier zero point after, feeding machine begins feeding from t0, material is fallen on the scale body;
As Fig. 3＜B〉shown in, at lasting feeding, because of the belt movement on the scale body (seeing the direction of arrow), material can be distributed on the scale body from t0 to the t1 feeding machine, and the control system command stops feeding when reaching t1;
As Fig. 3＜C〉shown in, when stopping feeding to t2 (about 2～3 seconds of t1～t2), system determines the general assembly (TW) of material on the scale body immediately; When weighing, owing to there is not material to fall, by weighing, the impact in the time of also can eliminating the material whereabouts is to metering result's influence under static relatively situation for the material on the scale body;
As Fig. 3＜D〉shown in, when material continues to run until t3 (about 1～2 second of t2～t3), material begins to fall, and start feeding machine again and begin feeding this moment;
As Fig. 3＜E〉shown in, after last time material leaves the scale body, get back to again＜B the figure state, so repeat, realize being interrupted blanking and weigh.
2. measure the method for scale body tare weight (zero point)
Control system is almost constantly measured the zero point of each feed weigher seeking an opportunity, and measures once within least six minutes, guarantees quantification stability.When needs are zero to a certain feed weigher school, slightly accelerate its speed, make it extrude about 10～20 seconds of school zero-time, it is out of question extruding this time within six minutes, therefore each feed weigher can be continually suppressed zero automatically, fully guaranteed each feed weigher correctness at zero point.
3. synchronous method of preparing burden
When needs are realized the weighing of various materials of specific proportioning, can utilize the utility model to prepare burden synchronously.Carried out feed simultaneously, weighed by many feed weighers 1, every feed weigher is responsible for a kind of material, unifies control by control system.
When preparing burden synchronously, stipulate a synchronizing cycle, for example may be prescribed as 30～60 seconds this synchronizing cycle, control system at first guarantees to finish exactly the blanking amount of each feed weigher in this cycle length in one-period, make certain scale putty occur as certain interference, do not reach setting down in specified period, then other each scales are in waiting status, after all feed weigher blankings are finished, just carry out the synchronous blanking cycle of the next one.Example: certain system synchronization cycle length is 30 seconds, be provided with two feed weighers, the blanking amount of first platform balance in synchronizing cycle is 50kg, the blanking amount of second platform balance in synchronizing cycle is 30kg, this synchronous baiting method guarantees that at first first platform balance descends the 50kg material exactly in 30 second time, 30kg material under second platform balance.When certain reason the putty situation occurs as second platform balance, the 20kg material may occur only having descended in 30 seconds, this moment, first platform balance was expected as the 50kg that was over down in 30 seconds, but still was in waiting status, after second platform balance has been finished 30kg blanking amount, just can carry out the synchronous blanking cycle of the next one.Adopt regularly synchro control blanking, can guarantee distributing precision.
The utility model utilizes synchronous control mode to guarantee that 100% carries out prescription, effectively improves measuring accuracy and distributing precision, uses on industry prescription control production line, has very strong practicality.
