Embodiment 1

[0028] In this embodiment, the automatic weighing instrument is used to realize the weighing segmental peeling method of the belt scale. like figure 2 and image 3 As shown, on the conveyor belt 2 of the belt scale, the first and second induction markers 7 and 8 (magnets, iron blocks, etc. all can be) are respectively embedded with a predetermined distance D. An inductive monitoring device 6 capable of detecting the passage of the markers is installed on the lower frame where the markers pass. When the two markers pass through the inductive monitoring device respectively, two pulses N can be generated sequentially. 1 with N 2 . In view of the fact that the position of the first sensing marker is the basis of the fixed point of delivery, according to the following formula, the position of the first marker can be confirmed by means of the two pulses:

[0029] |(T N2 -T N1 )-D / V|≤M

[0030] In the formula, T N1 - The arrival time of the first induction marker, T N2 - Ar...

Abstract

The invention relates to a weighting and section cutting method for belt weigher, belonging to weighting and measuring technical field. The method comprises disposing a first sensing marker on preset position of convey belt of the belt weigher, disposing a monitoring device and a impulse speed measuring sensor on frame of the belt weigher, recording intervals between two times when the first sensing marker to be detected and total impulse amount emitted by the impulse speed measuring sensor during the time interval; uniformly dividing the whole convey belt in average sections according to preset amount, and dividing the total impulse amount into numbered impulse groups corresponding to the sections; respectively recording tare weight and gross weight of each section ; sequentially subtracting section gross weight of each numbered impulse group with corresponding tare weight, accumulating net weight of material to be conveyed in each section of convey belt in order to obtain total weight of the material to be conveyed. The method can eliminate difference between fixed threshold and linear density average of each convey belt section, and avoid phenomenon of ''none material weighting'' or ''material not weighting'', effectively enhance the weighting accuracy.

Description

technical field [0001] The invention relates to a tare method for weighing with a belt scale, in particular to a segmented tare method for weighing with a belt scale, and belongs to the technical field of weighing and measurement. Background technique [0002] The belt scale is the most efficient and widely used among all kinds of bulk material automatic accumulative weighing instruments at present. Its typical structure and principle are: the weighing mechanism of the belt scale is installed on the frame of the belt conveyor, and placed on the conveyor The belt is below the belt, and the material is conveyed above the conveyor belt. When the conveyor belt carries the material through the weighing platform of the belt scale, the load sensor is affected by the gravity of the material, the self-weight of the mechanical components of the force measuring device and the weight of the conveyor belt on the weighing platform, and weighs the gross weight (see figure 1 ). [0003] I...
