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

Embodiment 1
[0020] Embodiment 1, storing a single batch
[0021] Such as figure 1 As shown, set the basic parameters, set the total weight of the normal batch in the PLC controller Q = 6000kg, the length of the full cabinet spread L = 12m, and the distance L between multiple batches of materials entering the same storage cabinet 间 = 2m;
[0022] The batch material weight Q 1 =3000kg, calculate L 长1 =L*Q 1 / Q=6m, the starting position of laying material is at the discharge end L of the storage cabinet 始1 =0, end position L 终1 = L 长 = 6m, so the paving range is between 0m and 6m;
[0023] If the batch material weight Q 1 =6200kg, Q 1 >Q, it can be calculated that L 长1 =12.4m, beyond the maximum allowable paving range, take L for this 长1 =12m, the range of material spreading is between 0m and 12m, allowing full container material spreading;
Embodiment 2
[0024] Embodiment 2, storing multiple batches
[0025] Such as figure 2 As shown, select the first batch of materials to enter the storage cabinet, and the weight of the materials is Q 1 =1500kg, calculate L 长1 =L*Q 1 / Q=3m, the paving range is between 0m and 3m;
[0026] Select the second batch of materials to enter the storage cabinet, and the weight of the materials is Q 2 =1000kg, due to Q 2 长2 =0.2*L=2.4m, the distance between the starting position of laying material and the end position of the first batch of material is L 间 =2m, so the starting position of paving is L 始2 = L 间 +L 长1 =5m,L 终2 = L 始2 +L 长2 =7.4,m, so the laying range of the second batch of materials is between 5m and 7.4m;
[0027] Select the third batch of materials to enter the storage cabinet, and the weight of the materials is Q 3 =1800kg,L 长3 =L*Q 3 / Q=3.6m, the initial position of paving is L 始3 = L 间 *2+L 长1 +L 长2 =9.4m, L 终3 = L 始3 +L 长3 = 12m, so the laying range of the thir...

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...
