Description

Narrow-band sorting machine capable of sorting special-shaped pieces and intelligent control method thereof Technical Field The invention relates to the technical field of logistics sorting equipment, in particular to a special-shaped piece narrow-band sorting machine capable of sorting and an intelligent control method thereof. Background In logistics sorting field, narrow-band sorting machine is widely applied to goods sorting work in industries such as express delivery, electronic commerce and the like because of compact structure and high sorting efficiency. The conventional narrow-band sorting machine is mainly designed for regular cubes, cuboids and other standard components, and the core of the conventional narrow-band sorting machine depends on narrow-band conveying belts which are arranged in parallel to realize longitudinal conveying and transverse sorting of cargoes, so that sorting requirements of conventional standard components are met. However, in an actual logistics scene, a large number of special-shaped pieces such as round barrels, irregular furniture accessories and special-shaped pipes exist, the special-shaped pieces are easy to deviate due to irregular shapes and gravity centers, and when conveyed on an existing narrow-band sorting machine, the problems of rolling, deviation, seam clamping and the like are very easy to occur, so that the sorting error rate is high, and equipment faults are frequent. In order to solve the problem of sorting the special-shaped pieces, some manufacturers optimize the sorting by adding fixed flanges, adjusting narrow-band intervals and the like, but the fixed flanges can only adapt to special-shaped pieces with specific sizes, have poor universality and are easy to rub and collide with the surfaces of the special-shaped pieces to cause damage to the goods, while the narrow-band intervals are adjusted to reduce the risk of clamping seams, the core problem of rolling deflection of the special-shaped pieces cannot be solved, and a large amount of manual auxiliary positioning is still needed to seriously influence the sorting efficiency. Meanwhile, the positioning limiting structure of the conventional narrow-band sorting machine is in a fixed mode, the limiting range cannot be adjusted in a self-adaptive mode according to the actual profile of the special-shaped piece, the limiting height is fixed, and the limiting stability is insufficient for the special-shaped piece with higher height or with the upper gravity center, so that dumping occurs easily during sorting and steering. In addition, the control method of the existing sorting machine lacks specific special-shaped piece identification and self-adaptive limiting logic, so that full-flow automatic control from detection, positioning and limiting to sorting of special-shaped pieces is difficult to realize, and the application of the special-shaped piece sorting machine in a special-shaped piece sorting scene is further limited. Therefore, a narrow-band sorting machine which can be self-adaptive to the profile of the special-shaped piece, is stable in limiting and accurate in sorting and can realize intelligent control of the whole process is needed, so that the problems of low sorting efficiency, poor stability and insufficient universality of the special-shaped piece in the prior art are solved. Accordingly, there is a need for further improvements in the art of existing logistics sorting apparatus. Disclosure of Invention The invention aims to provide a narrow-band sorting machine capable of sorting special-shaped pieces and an intelligent control method thereof, which are used for realizing self-adaptive profile limiting, stable conveying and accurate sorting of the special-shaped pieces, improving the automation degree and reliability of sorting the special-shaped pieces and reducing the cost of manual intervention. In order to achieve the above purpose, the present invention adopts the following scheme: The narrow-band sorting machine capable of sorting special-shaped pieces comprises a logistics input channel and a sorting channel connected to the logistics input channel, wherein a plurality of sorting narrow-band assemblies are longitudinally and uniformly distributed on the sorting channel, and a linear array positioning shaft assembly is arranged between two adjacent sorting narrow-band assemblies; The linear array positioning shaft assembly comprises a plurality of elastic telescopic positioning shafts uniformly distributed along the transverse direction, a range-extending telescopic positioning shaft is arranged in the elastic telescopic positioning shafts, a synchronous shrinkage oblique ejection structure is arranged between the sorting narrow-band assembly and the elastic telescopic positioning shafts, a range-extending driving structure is arranged between the elastic telescopic positioning shafts and the range-extending telescopic positioning shafts, and a height correction oblique guide
