Method for automatically adjusting position of paving material of storage cabinet

Abstract

The invention discloses a method for automatically adjusting the position of a paving material of a storage cabinet, and the method comprises the steps: setting basic parameters, setting a normal batch total weight Q in a PLC controller according to a technological standard, setting the overall length of the paving material in the cabinet as L, enabling materials of a plurality of batches to enter the same storage cabinet, and placing the materials at L intervals; building a model formula in the PLC controller, calculating the length L<length n> of the paving material, the starting position L<start n> of the paving material and the end position L<end n> of the paving material according to the weight Qn of the cabinet in the current batch; enabling L<length n> to be equal to 0.2*Lm when Qn is less than 0.2*Q; enabling L<length n> to be equal to L*Qn / Q when Qn is not less than 0.2*Q; enabling the starting position L<start 1> to be zero when n is equal to 1, enabling the end position L<end 1> to be equal to L<length 1>, and enabling the material to enter from a material discharging end of the storage cabinet; enabling the end position L<end 1> of the paving material to be L when the end position L<end 1> is greater than L; enabling the end position L<end n> to be the sum of L<start n> and L<length n> when n is greater than 1; and forbidding storage if the end position L<end n> is greater than L. The method can precisely and efficiently adjust the position of the paving material in the storage cabinet during driving according to the batch weight, and can achieve the segmented and simultaneous storage of materials in a plurality batches in the storage cabinet.

Description

technical field [0001] The invention relates to a method for automatically adjusting the laying position of storage cabinets, belonging to the field of automatic control of tobacco shredded equipment. Background technique [0002] Storage cabinets are widely used in tobacco production, and large storage cabinets are required in premixing, leaf storage, and silk storage. Huge, with a size of two or three meters wide and more than 20 meters long, some of them will adopt a double-layered top-to-top craft layout. [0003] According to the requirements of the batch production mode, under normal circumstances, each batch of feed material is more than 6,000 kg, and the material is laid in the form of driving back and forth to and fro. The material is required to be laid evenly. The feeding roller can effectively loosen the agglomerated materials, and at the same time ensure the stability of the discharge flow at the normal bottom belt speed. [0004] However, when these large sto...

Problems solved by technology

However, the above methods all require manual participation in the setting of the material spreading range, which cannot be automatically adjusted according to the batch weight, and the control is not precise enough and the efficiency is not high

And the above-mentioned method cannot realize the special requirement that multiple small batches are stored in sections in one storage cabinet at the same time
