A method for automatic centering of aluminum coils by transport trolley

Abstract

The invention relates to a method for automatic centering of an aluminum coil on a cargo location by a transport trolley. The actual distance measured from the center of a fixed saddle is A; the values ​​B and C of the front and rear edge positions of the coil are measured; The horizontal distance difference is Y, get the coil center position D and calculate the coil offset E; judge whether the absolute value E of the coil offset is greater than the maximum offset Z, and if so, perform alignment; otherwise, no alignment is required ; Judgment |F‑D|<=Z, if so, the trolley lifts the coiled material, walks towards the center of the fixed saddle, and falls down after it is in place, then there should be F=A|E|<=Z coiled material alignment Finish; or place the coil on another fixed saddle, at this time the F value should be set to the value of the center of the new target saddle; otherwise, continue to align. The invention adopts the transport trolley to automatically find the center of the aluminum coil in the cargo position, instead of adjusting the centering by hoisting the coil with the crane or man-operating the centering of the trolley, which has high precision and high efficiency and reduces repetitive labor of operators.

Description

technical field [0001] The invention relates to the field of cargo storage, in particular to a method for automatic centering of aluminum coils in storage positions by transport trolleys. Background technique [0002] At present, the transportation and storage of aluminum coils outside the three-dimensional coil warehouse of the aluminum processing plant mostly adopts the form of a transport trolley with a hydraulic jacking mechanism and a saddle structure. Based on the above configuration, in order to ensure the safety and stability of the transportation process, it is required that the center point of the aluminum coil should coincide with the center point of the saddle space as much as possible. During the storage process, the transport trolley should be lifted at the center point of the aluminum coil. goods. In order to achieve this technical goal, the aluminum coil transport trolley should be equipped with a control algorithm that automatically finds the center point o...

Problems solved by technology

However, since the crane and the terminal are independent of each other, manual adjustment is time-consuming and labor-intensive, so the function of automatic centering of aluminum coils on the cargo location by the coil transport trolley is very necessary
