2Till the accuracy of measuring of)≤scale.Referring to, the materials calibration workflow diagram of Fig. 6.
(2) material shaping and material load Control work process
No matter enter in the feed bin material shapes how with what of load, but flow out the shape of feed bin material and the size of load, by the shape of the gate of feed bin and the size decision of unlatching, when the gate enable position was constant, then material shapes and the payload through gate all was in more stable state.
Upper and lower level-sensing device is used for controlling the material load.According to supplied materials large and small selection discharge gate 15 enable positions of loading.As choose a position (even the material position of 3 li of feed bins is in the middle of the upper and lower level-sensing device), then the material load from 3 li outflows of feed bin is just decided by discharge gate 15 centre positions, and more stable.When the material that enters feed bin 3 when flowing out the material of feed bin 3, the material level that feed bin is 3 li promptly rises, when waiting to rise to the level-sensing device position, last level-sensing device promptly sends the signal that starts discharge gate 15, and it is moved up, and the material load that flows out this moment increases, thereby the material level of 3 li of feed bins is descended rapidly, when reaching the level-sensing device position, last level-sensing device promptly sends the startup signal strobe, makes it return to original position; When the material position of 3 li of feed bins drops to the level-sensing device position, following level-sensing device promptly sends control discharge gate 15 signals, it is moved down, flowing out the material load this moment reduces, thereby the material level of 3 li of feed bins is risen rapidly, when material level reached the level-sensing device position, following level-sensing device promptly sent control discharge gate 15 signals, makes it return to original position.
In sum, under upper and lower level-sensing device control, discharge gate 15 is mediated, the material load is in steady state (SS) all the time on the belt 9, to improve the accuracy of measuring of uclear scale.
In concrete embodiment of the present invention, feed bin 3 is a rectangular parallelepiped, and the electronic sliding plate 7 of feed opening 8 usefulness opens and closes; Select electronic travel switch 14 control discharge gates 15 positions for use; Upper and lower level-sensing device is optional uses up electric level-sensing device; Feed bin Vib. 2 is selected electromagnetic vibrator for use; Feed bin jacking gear 5 is selected electronic eccentric wheel structure for use or is selected leading screw pushing tow structure for use or select the Motor Driven Elevating Calabash structure for use, and weighing apparatus 4 can be selected pressure transducer for use; The iron plate structure that support plinth 6 adopts four support columns to support; Control device can be selected PLC Programmable Logic Controller or Industrial Control Computer for use, or the signal of this system is directly inputted to the control system of uclear scale, finishes metering and control function by this system.
This system's social demand is big, China has the uclear scale Yue Wantai of online military service now according to a preliminary estimate, its materials calibration all is manually to do, scale if any 20% needs technological transformation, then the demand of this system will be added the demand of the uclear scale of new installation more than thousands of, and its market is bigger, production has got in batches, and the production economic benefit of enterprises is conspicuous so.Scale in labour is mixed this system and is spent seldom just can save many man-hours, and need not stop production and just can demarcate automatically, thereby creates more economic benefit for the user.In a word, self economic benefit and social benefit of this system is very considerable.
