Unloading car control method for multi-point unloading

Abstract

The invention relates to an unloading car control method for multi-point unloading. The unloading car control method comprises the steps that (1) when an unloading car reaches a specified unloading site, the position of the unloading car is transmitted onto an operation interface of a control system in real time; and after the unloading car stops moving under the effect of a corresponding limit switch, the control system starts a belt conveyor to convey materials, and the materials are unloaded to corresponding unloading ports through the unloading car; (2) radar level gauges are arranged at the tops of stock bins, and high level alarms are arranged on the upper portions of the stock bins; (3) blockage alarm devices are separately arranged at discharge outlets of the unloading car; and (4)a video monitor is arranged above one side of each stock bin to check the unloading condition of the unloading car in real time. By adoption of the unloading car control method for multi-point unloading, automatic control can be achieved when the unloading car discharges materials to multiple stock bins, and control over the material levels in the stock bins and blockage alarm are achieved, so that the unloading efficiency is improved, production can conducted smoothly, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of material conveying, in particular to a method for controlling an unloading trolley during multi-point unloading. Background technique [0002] In the process of material transportation, multiple material bins are often loaded by the movable cloth trolley installed on the belt conveyor. At present, manual operation of the cloth trolley is often used on site, but this method has the following problems: First, the distribution trolley The allocation is unreasonable, resulting in low utilization rate and unloading efficiency of the cloth trolley; second, the material level in the silo cannot be accurately estimated through manual observation, resulting in the inability to make full use of the remaining space in the silo, and It is easy to leak when the material level is high; the third is that the sundries mixed in the material are easy to block the discharge port. If it is not found in time, it will cause a ...

[0002] In the process of material transportation, multiple material bins are often loaded by the movable cloth trolley installed on the belt conveyor. At present, manual operation of the cloth trolley is often used on site, but this method has the following problems: First, the distribution trolley The allocation is unreasonable, resulting in low utilization rate and unloading efficiency of the cloth trolley; second, the material level in the silo cannot be accurately estimated through manual observation, resulting in the inability to make full use of the remaining space in the silo, and It is easy to leak when the material level is high; the third is that the sundries mixed in the material are easy to block the discharge port. If it is not found in time, it will cause a large amount of leaking, which will affect the smooth progress of production.
