As shown in fig. 7, the invention proposes one in order to further increase measurement accuracy and to the resolving power of light and small material
Kind has the handling of goods and materials cabinet of auxiliary support mechanism.First generation multi-layer drawers described in Fig. 1-6 concentrate weighing materail tube
It manages in cabinet application, material is accommodated in drawer 2, and drawer 2 is mounted in cabinet body 5, and cabinet body 5 is located at (this on cabinet body chassis 3 again
In drawer 2,5 cabinet body chassis 3 of cabinet body be referred to as frame), because the reason of intensity, accommodate the frame of material from focusing on some
In the case of can be greater than accommodated material weight, largely waste effective measuring range of weighing sensor 6.In order to
Guarantee material measuring range, need to select the weighing sensor of wide range under normal circumstances, so that the weight of entire material cabinet is all
In range, while needing sensor that there is the measurement accuracy and resolution ratio to meet certain requirements again, to sense small weight
Material variation.Sensor has wide range and high-resolution simultaneously, becomes insoluble contradiction.
Assuming that weight of material is 50kg, frame self weight is 50kg, then needs that the C3 grade that full scale is 100kg is selected to sense
Device, the precision of the sensor is the 0.033% of full scale, then the uncertainty to be weighed is 33g, that is to say, that choosing
It is 33g with the distinguishable pts wt of the material cabinet of C3 grades of sensors, part of the weight less than 33g can not will accurately carry out
It differentiates and counts.
If auxiliary support mechanism is arranged in the lower section of cabinet body, fall major part with the upward constant support dynamic balance of 40kg
Cabinet body self weight.The maximum weight being actually loaded on sensor becomes 60kg, can thus use the C3 that range is 60kg instead
Grade sensor, then the uncertainty to be weighed becomes 20g, that is to say, that select the material cabinet of C3 grades of sensors distinguishable
Pts wt be 20g, improve resolving accuracy.
Meet the requirement of the above counteracting or reduction frame weight, it is necessary to which Auxiliary support unit 20 is able to achieve constant force branch
Support, i.e., when weight of material changes in material cabinet, still remain unchanged the support force of material cabinet.To guarantee that system is stablized,
This support force is generally required to be less than the weight of vacant material cabinet, difference is maintained at 10kg or so.
Fig. 8 and Fig. 9 is the material cabinet support construction schematic diagram that piston rod type auxiliary support mechanism is used in embodiment one.
Cabinet body chassis 3 is lower in Fig. 8 is provided with four weighing sensors 6, and every weighing sensor 6 is supported on the ground by lower margin 4.
One piston rod type auxiliary support mechanism is respectively set in 3 two sides middle position of cabinet body chassis, realizes the constant force branch to cabinet body
Support.
Piston rod unit includes sealed cylinder block 31, the body of rod 32 and sealing ring that can slide up and down in sealed cylinder block 31
38.The upper end 33 of the body of rod 32 is step-like structure, and upper end is thick intermediate thin；The upper end 33 of the body of rod 32 and sealed cylinder block 31
Top cover constitutes upper cavity 34；The intermediate position outer ring of the body of rod 32 and the cylinder body of sealed cylinder block 31 form central cavity 35；
The setting of 32 upper end 33 of the body of rod is by several through-holes 36 for being connected to upper cavities 34 and central cavity 35；Upper cavity 34 and middle part
Gassy or the pressure medium of gas-liquid mixed in cavity 35, when the body of rod 32 is mobile, pressure medium can flow in two cavitys
It is dynamic.
31 upper end of sealed cylinder block is provided with unidirectional charge valve 37, and the gas or gas of setting pressure are charged into for upper cavity 34
After liquid mixture, unidirectional charge valve 37 seals at once；It is provided with sealing ring 38 between sealed cylinder block 31 and the body of rod 32, realizes
The movable sealing of pressure medium in sealed cylinder block 31.The body of rod 32 is pushed out after pressurising, rests on a certain position of sealed cylinder block 31
It sets, external thrust is constant.The upper support of sealed cylinder block 31 is on the upper edge of cabinet body chassis 3 in use, the body of rod 32
Lower end then supports on the ground.
In order to illustrate the constant force support concept of above-mentioned piston rod, following explanation is carried out:
Assuming that the body of rod 32 all stretches out outside cylinder body, at this time the gas of cylinder interior after pouring gas-liquid in sealed cylinder block 31
Liquid volume is C, pressure P, and the cross-sectional area in the middle part of the body of rod is A, then the external thrust of the body of rod is F=AP；
Assuming that the body of rod becomes extrapolability to push-in distance s, the body of rod inside sealed cylinder block
To above formula derivation, it can show that thrust variation rate is
If taking P=1Mpa, s=50mm, bar diameter 10mm, sealed cylinder block length be 200mm, internal diameter 18mm, i.e.,
A=78.54mm2, C=5.089x104mm3
Thrust variation rate, which can be calculated, is
Material metage process is quasistatic process, and expanding-contracting action does not occur substantially for piston rod.For normally accessing object
Material operation, the deflection of strain transducer add the deflection of cabinet body, are usually no more than 0.1mm.It is possible thereby to estimate, push away
Power variation will be no more than 0.0142N, be roughly equal to 1.4g.So small thrust variation, it is believed that support force is invariable, insufficient
To be impacted to measurement.
Figure 10-12 gives working principle when Auxiliary support unit 20 is lever counterweight element in embodiment two, by four
A fixed pivot, four lever arms and one form with heavy lead.Four lever short arm ends are supported on cabinet body chassis following table upwards
Face, long arm end are connected firmly with heavy lead.Gravity with heavy lead translates into the upward constant support power in four lever short arm ends, supports
Disappear most cabinet body self weight.The weight with heavy lead is constant when due to picking and placing material, by leverage to cabinet body chassis
Support force is constant force.
