Embodiment Construction

[0031] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] The present invention aims to comprehensively use the encoder and the laser range finder to detect the rolling process, use the programming method to overcome the respective advantages and disadvantages of the encoder and the laser range finder, and switch to the laser range finder in time when the encoder is detected to be inaccurate When the laser range finder is detected to be inaccurate, it will switch to the encoder for position tracking in time.

[0033] The specific method is as follows:

[0034] Since the principles of the laser rangefinder and the encoder are different when measuring the position, the position tracking error caused by it is also different, and different judgment methods need to be u...

Abstract

The invention relates to a coil conveying trolley, in particular to a coil conveying trolley comprehensively using a laser range finder and an encoder, the coil conveying trolley comprises a coil conveying trolley body, a walking beam is arranged on the coil conveying trolley body, a plurality of saddles are arranged on the walking beam, and material coils are arranged on the saddles. The laser range finder and the encoder are further arranged on the coil conveying trolley body, and a reflector is further arranged in the coil conveying direction of the coil conveying trolley body. The positionof the coil conveying trolley is accurately controlled, meanwhile, under the condition that one of the encoder or a laser velocimeter breaks down or is inaccurate, positioning errors of the coil conveying trolley can be avoided, and the production continuity and the low fault probability are guaranteed.

Description

technical field [0001] The invention relates to a rolling trolley, in particular to a rolling trolley based on the comprehensive use of a laser range finder and an encoder. Background technique [0002] As the main equipment of cold rolling, the coil transport trolley is used to transport finished coils and raw material coils. It plays a very important role in the automatic production of cold rolling. The traditional use of encoders for positioning has inaccurate positions and is prone to problems such as coil drop. [0003] When using encoders for positioning, rail slippage can cause the measured speed to be higher than the actual speed. When the laser range finder is used, the occlusion or vibration of the object will cause the measurement speed to jump. Therefore, when only an encoder or a laser rangefinder is used, the measurement position will be inaccurate, resulting in inaccurate positioning, and it is easy to cause roll drop, which cannot guarantee the safety of ro...
