Coil unloading positioning device and method at a coil collection station

Abstract

The invention discloses a coil unloading positioning device and method at a coil collecting station, which are used to solve the problem of difficult and inaccurate positioning in the coil unloading at the coil collecting station in the prior art. A coil unloading positioning device at a coil collection station includes a trolley, a C-shaped hook, a light curtain measuring sensor and a control device, and the trolley is equipped with a touch mechanism, an encoder and a limit switch; the touch mechanism is used for The limit switch is triggered after the trolley touches the bottom of the coil when it is loaded; the control device is used to control the encoder to record the rising height of the trolley according to the trigger signal; the light curtain measures The sensor is used to center the center position of the C-shaped hook and the center position of the coil before the trolley arrives at the C-shaped hook to unload the coil; the upper edge of the lower end of the C-shaped hook and the double mandrel The upper edge of the horizontal axis is on the same horizontal line. The device and method provided by the invention improve the positioning accuracy and work efficiency.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a positioning device and method for coil unloading at a coil collecting station. Background technique [0002] In the prior art, after long-term measurement and observation of coil unloading at the coil collection station, it was found that during the centering positioning and unloading process of the trolley, under the condition that the positioning is relatively accurate, the coil is often placed on the ground due to the lowering of the trolley. During the process of the C-shaped hook, the C-shaped hook that is often pressed is tilted, which breaks the balance, causes the coil to fall down, and also makes the positioning process fail, and readjustment is more troublesome. If the coil is not on the C-shaped hook during the unloading process, and the arm of the trolley has been opened at this time, the coil will be scattered, the coil will become longer, the center of gravity wil...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems existing in the prior art that the positioning is difficult and inaccurate when the coil is unloaded at the coil collection station, or that the C-shaped hook is easily bent when the coil is unloaded even if the positioning is accurate, resulting in positioning failure.
