Abstract
The invention is a detecting method of the electronic belt scale. The process is: first to set an empty belt segment on the transporting belt and place the standard load on the empty belt segment, when the standard load passes the weighing region, the belt scale will sample to weigh, then to treat the data of the sampling result and compare with the standard load value to revise. The device is the chain yard which is connected by many same weight of the standard weight block. The invention has the high confidence ratio; the detecting time is short and has the good adaptability.
Description
Technical field
The present invention relates to band conveyor and is carrying, measuring in the process of industrial material, the method and the device that belted electronic balance are carried out automatic gauging.
Technical background
Belt conveyer scale has been widely used in weighing automatically in the industrial bulk cargo conveying.For safeguarding belt conveyer scale weighing accuracy, must regularly test to belt conveyer scale.The present method of inspection both domestic and external has two kinds: a kind of is check in kind, and promptly the result with static scale weighing material object checks belt conveyer scale.The advantage of the method for inspection in kind is that degree of confidence is the highest, but check investment in kind is bigger, and exists proving time long, effort, and material is repeatedly by problems such as transhipments, and the process conditions of check in kind can't be satisfied in particularly most scene.Another kind method is to adopt the check of simulation load device, usually adopt link code, dolly sign indicating number, rolling chain code, circulating chain code etc. to load on the empty belt of material as the end that normal loading is placed on operation, by belt conveyer scale its normal loading is carried out the weighing sampling, again sampling result is carried out data processing, and relatively reach correction with the normal loading actual weight value of setting.The simulation load check all is to carry out under the situation of empty belt, can only simulate a certain section feed status in kind on the whole conveyor surface of belt feeder, the so big belt tension and the variation of tension force when not producing in the actual production process cloth full with substance on the whole conveyor surface of belt feeder, therefore the simulation load check is compared with check in kind, still there is certain error, particularly the operation conditions of every band conveyor is had nothing in common with each other, can't obtain and check in kind between fixed relationship, the check of just comparing after therefore every band conveyor must adopt check in kind to revise.
Summary of the invention
Difficult in order to solve the check in kind of above-mentioned belt conveyer scale, the low problem of letter rate is put in the simulation load check, the invention provides a kind of belted electronic balance method of inspection and device thereof, can utilize the software and hardware resources in the belt conveyer scale instrument, belt conveyer scale is carried out dynamic check not changing under the mass transport operating mode of the whole conveyor surface of belt feeder, reach the purpose of check in kind, improve the letter rate of putting of test mode.
The method of inspection of a kind of belted electronic balance of the present invention comprises the steps:
(1) just setting up one section empty belt section that does not load material on the belt conveyor at convey materials;
(2) on above-mentioned empty belt section, be placed on equiponderant normal loading on the unit length;
(3) sensor of belted electronic balance carries out the weighing sampling when normal loading is regional by the weighing of its scale frame;
(4) by the belted electronic balance instrument sampled result is carried out data processing, and relatively reach correction with the normal loading actual weight value of setting.
In order to simulate the mass transport operating mode better, above-mentioned normal loading is divided into plurality of sections and link successively on its length direction, thereby the tension force of this section belt and situation of change thereof are similar to the mass transport operating mode.
The present invention is used for the device of the above-mentioned method of inspection, comprises a chain code as normal loading, and the standard weight gauge block that this chain code is equated by some shape identical weight links successively and forms.
Because the present invention adopts and is just placing normal loading on the belt conveyor at convey materials, automatically belt conveyer scale is carried out dynamic check not changing under the mass transport operating mode of the whole conveyor surface of belt feeder, reach the purpose of check in kind, thereby the letter rate of the putting height of test mode.And check very conveniently, and dead band is being set on the belt, on dead band, is placing chain code and chain code is measured sampling and be easy to realize automatic control, thereby proving time to be short, adaptability is strong.
Fig. 1 is a principle of work synoptic diagram of the present invention.
Fig. 2 is belt conveyer scale sampling, check program block diagram.
Embodiment
Method of the present invention is performed such: as shown in Figure 1, earlier just setting up one section empty belt section L that does not load material on the belt conveyor [4] in convey materials [1], arrow is a belt direction of travel among the figure, placing the equal normal loading of unit weight then on empty belt section L is chain code [2], and the standard weight gauge block that this chain code is equated by some shape identical weight links successively and forms.The sensor [5] of belt conveyer scale carries out the weighing sampling when normal loading [2] is regional by the weighing of its scale frame [6], by the belt conveyer scale instrument sampling result is carried out data processing again, and relatively reaches correction with the normal loading actual weight value of setting.3 is carrying roller among the figure.Chain code can carry out folding and unfolding automatically with windlass.
The present invention also adopts the PLC control circuit to setting up empty belt section, place chain code and weighing sampling implementation control automatically.Promptly establishing the feed motor on belt stops the trigger point and restarts the trigger point, when belt runs to the feed motor and stops the trigger point, make trigger point triggering for generating electric signal, when the PLC system detects this trigger pip, the PLC control circuit stops the feed motor, when belt conveyor operation " L " apart from the time (having set up one section empty belt section that does not load material) make and restart trigger point triggering for generating electric signal, the PLC control circuit restarts the feed motor, the feed motor stop and the process that restarting in the PLC control circuit to make the draw off gear of chain code be that windlass lies in chain code on the L section exactly.
The belt conveyer scale instrument is sampled at check weighing always in said process, the sampling beginning is set respectively and finishes the contact at carrying roller B place and A place, when the belt b point that is loaded with chain code runs to carrying roller B point, as shown in Figure 1, running to carrying roller A point to the belt a point that is loaded with chain code ends, this section is the efficiently sampling of instrument to chain code, and instrument the sampled result of this moment can be stored and the standard weights of this section chain code automatic and that set in advance compares, proofreaies and correct.
The belt conveyer scale check program as shown in Figure 2, at first be to empty to demarcate the cumulative amount buffer zone, set demarcation cumulative amount pointer and demarcate timer clearly, when to the timing the set belt b point that promptly is loaded with chain code begin demarcation when running to carrying roller B point, the storage cumulative amount is also removed timer, when running to carrying roller A point, finishes the belt a point that is loaded with chain code sampling, show sampled data, calculate again and show assay.
