Method for fast stepless regulating and controlling cabinet storage capacity in storage cabinet system

Abstract

The invention discloses a method used for regulating the storing capacity of a holder rapidly and steplessly, which relates to a method used for regulating the storing capacity of a leaf (or cut) tobacco holder system in the tobacco industry. The steps for controlling the holder storing capacity rapidly and steplessly are as follows: 1) arranging a laser distance sensor at the discharging end of the distributor rail of the holder and a reflecting plate on the distributor; 2) inputting a set value of spread material length into the control system of a computer; 3) transmitting the instant actual distance information measured by the laser range sensor to the control system of the computer; 4) the control system of the computer compares the set value of burden distribution length and the instant actual distance measured by the laser range sensor and then controls the running of the distributor; repeating the steps of 3) and 4) and running repeatedly and cyclically until the spread material of the holder is finished. The method of the invention has the advantages of simplicity and feasibility, high precision of distance measurement, flexible using and convenient operation. The effective capacity of the holder can be regulated discretionarily and steplessly from 0% to 100%, and the method can meet the need of flexible production.

Description

technical field [0001] The invention relates to a tobacco leaf (shredded) storage cabinet system used in the tobacco industry and a method for rapidly and steplessly regulating the storage capacity of the storage cabinet system similar to the storage cabinet system. Background technique [0002] In the tobacco industry, the storage cabinet system not only has the function of storage, but also has the function of mixing formula raw materials, blending uniformly and balancing production. Therefore, there are a series of conventional operation steps to realize these functions. Generally speaking, when the production is carried out according to the design cabinet capacity, the distribution vehicle distributes the material to the set position of the distribution vehicle step by step and forms a long strip of material, and the distribution vehicle reciprocates between the proximity switches at both ends of the storage cabinet , the material is spread on the bottom belt of the stor...

Problems solved by technology

This method has great limitations: firstly, due to the large weight of materials accumulated in the storage cabinet and the limited range of motor speed regulation, the adjustable range of bottom belt speed is narrow, which cannot meet the production needs with large differences in feeding amount, and has poor adaptability; Secondly, the frequency of the motor is not linearly proportional to the speed of the bottom belt. It is difficult to determine the corresponding frequency value of a certain speed. Generally, only a few commonly used speeds can be determined, and the flexibility is poor; Blending Uniformity of Leaf Components

Now production is gradually developing toward flexibility and refinement. In actual production, there are many situations in which there are many changes in the effective storage capacity of storage cabinets, and there may even be temporary changes in the effective storage capacity of storage cabinets. The system based on the proximity switch is obviously Unable to meet the changing needs of effective cabinet storage capacity
