AI Technical Summary

Problems solved by technology

like figure 1 As shown, when the uncoiler moves to the left and when the uncoiler moves to the right, the middle position of the actual stop of the uncoiler is inconsistent, and the error is relatively large (the diameter of the proximity switch is close to that in the figure, and the diameter of the most commonly used proximity switch is 30mm). The error is about 30mm, which will affect the position accuracy of the strip steel in the unit, especially when producing narrow gauge strip steel

Embodiment 1

[0036] The embodiment of the present invention relates to a positioning method, including the following steps:

[0037] S1: Set the left sensing element 11 and the right sensing element 12 on the object in sequence along the moving direction of the object 3 to be positioned, and set at least two proximity sensors in sequence along the moving direction of the object 3 to be positioned beside the moving path of the object 3 switch;

[0038] S2: Adjust the installation position of each of the proximity switches so that when the object 3 is located at the target positioning position, at least two of the proximity switches are correspondingly triggered;

[0039] S3: During the moving process of the object 3, the object 3 is positioned according to the sensing state of each of the proximity switches, and when the corresponding proximity switches are all in a triggered state, the object 3 reaches the target positioning position.

[0040] Among them, in this embodiment, corresponding...

Abstract

The invention relates to a positioning method. The method comprises: a left sensing element and a right sensing element are arranged at an object along a movement direction of a to-be-localized object and at least two proximity switches are arranged successively at a movement path of the object along the moving direction of the to-be-localized object; ; installation positions of all proximity switches are adjusted and thus when the object is located at a target positioning position, at least two corresponding proximity switches are triggered; when the object is moving, the object is localized according sensing states of all proximity switches; and when all corresponding proximity switches are in a trigger state, the object arrives at the target positioning position. The target positioning position of the object can be localized by using two proximity switches, so that the positioning precision can be improved effectively; and a positioning error caused by a large sensing area of the proximity switch can be eliminated.

Description

technical field [0001] The invention relates to a positioning method, which utilizes a proximity switch to detect the position of a positioning object. Background technique [0002] In the automatic production line of the metallurgical industry, there are many equipments that reciprocate in a straight line, such as uncoilers, etc., when in use, it is often necessary to determine three positions: the left limit position, the middle position, and the right limit position; two methods can be used for positioning, The first use is displacement sensor positioning, and the second is using proximity switches for positioning. The displacement sensor has high precision, but the cost is high; while the proximity switch is low in cost, but the precision is poor. For cost-effective considerations, proximity switches are often used for positioning in actual use. One induction block is welded on the moving uncoiler body, and three proximity switches are arranged on the fixed sliding tra...
