Start-stop control method and device for spreading vehicle of feeding machine

Abstract

The invention provides a starting and stopping control method and device for a spreading vehicle of a feeding machine. The method comprises the steps that S1, a control module obtains the amount of materials in a bin of the feeding machine and the position of the spreading vehicle of the feeding machine; S2, when the control module detects that the amount of the materials in the bin of the feeding machine is larger than a set amount of the materials and the position of the spreading vehicle of the feeding machine deviates from a preset area in the forward direction, the step S3 is executed; when the control module detects that the amount of the materials in the bin of the feeding machine is smaller than the set material amount and the position of the spreading vehicle of the feeding machine deviates from a preset area in the reverse direction, the step S4 is executed; S3, the control module controls conveying equipment of the previous procedure so as to reduce the material flow input into the bin of the feeding machine; and S4, the control module controls the conveying equipment in the previous procedure to increase the material flow input into the bin of the feeding machine. Compared with the prior art, the method and the device have the beneficial effects that the starting and stopping frequency of the spreading vehicle of the feeding machine can be reduced; and the fluctuation of the material flow of the next procedure is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a method and a device for reducing the frequency of starting and stopping of a feeder spreading vehicle. Background technique [0002] The feeder is mainly used in the tobacco silk production line. In order to meet the process requirements of the silk production line equipment, the feeder is often used in conjunction with metering tubes, electronic belt scales or other equipment. The feeder has the functions of lifting and storing materials. It can convey the material flow in a constant, uniform and quantitative manner. [0003] The feeding machine for silk thread is mainly composed of a spreading car, a silo, a hopper and a bottom belt. At present, the feeder and laying car used in the silk production line moves back and forth in a stepping manner within a limited range, so as to realize the purpose of picking up the materials transported from the previous process and...

AI Technical Summary

Problems solved by technology

[0004] In the actual silk production process, since the feeding machine and the laying vehicle are within the limited range, the materials transported by the previous process are transported to the silo by moving back and forth in the stepping mode of "walking and stopping". This makes the paving car start and stop frequently, which greatly reduces the service life of the paving car

[0005] In addition, because the material flow in the previous process will fluctuate, the feeder spreader will only distribute material to the silo according to the set step-by-step method, and cannot automatically adjust the material distribution method according to the fluctuation of the actual incoming material flow. So that the materials in the silo are stored in "waves"

As the feeder is the supplier of the material in the next process, this makes the flow of the inlet material in the next process fluctuate, which ultimately affects the product quality
