Embodiment Construction

[0037] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0038] In order to facilitate the understanding of the application scenarios of the present invention, by figure 1 A schematic diagram of on-site simulation of the mixed silk line of the present invention is provided. exist figure 1 Among them, each blending scale is arranged on the upper and lower sides of the shredded tobacco conveyor belt 1 running from right to left. It can be seen that the blending scale includes the main scale after drying 3, the small wire electronic scale 2, the stem silk scale 5, the expanded silk scale 4, the recycled short silk scale 6 and the side silk thread proportioning scale 7, and the distance from the fragrance adding scale 8 Each is different, so the delay time is also different, which needs to be obtained by testing.

[0039] like figure 2 As shown, it is a schematic diagram of...

Abstract

The invention relates to the weighing error monitoring method of an electronic scale. The weighing error monitoring method comprises the following steps: setting the delay time and the delay error of blending scales on the tobacco shred mixing line; calculating the weight difference caused by the delay error; collecting the accumulated weight of each blending scale at each moment, and pushing the value of the accumulated weight into a stack corresponding to each blending scale; extracting the accumulated weights before delay corresponding to each blending scale of the current moment from the stack, and summing the accumulated weights before delay to obtain the accumulated weight of a virtual scale; calculating the comparison deviation of the accumulated weight according to the accumulated weight of a flavor scale and the accumulated weight of the virtual scale; and determining whether the comparison deviation exceeds a preset deviation range, and, if yes, sending an alarm. The invention also relates to another weighing error monitoring method of the electronic scale. By determining whether the comparison deviation exceeds the allowable range, the method can monitor the weighting error and send an alarm to provide convenience for technicians to adjust the scale in time so as to reduce the occurrence possibility of process quality accidents.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for monitoring the weighing error of an online electric scale for mixing silk. Background technique [0002] The electric scale is an important equipment in the tobacco production line, and the constant flow feeding can be realized through the electric scale. The full name of the electric scale is the electronic belt scale, which is a measuring equipment for the production line to weigh the materials that pass through the conveyor belt continuously, and outputs the instantaneous weight flow and cumulative weight, such as: 4000kg / h; 60000kg. In tobacco production, it is necessary to add essence to the blended shredded tobacco. Blended shredded tobacco includes the shredded tobacco measured by the main scale after drying and the shredded tobacco weighed by other blending scales. Among them, the flow rate of shredded tobacco is measured by the main scale after d...
