Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automatic logistics equipment, especially to a slope conveying line capable of pitching and yawing. BACKGROUND

[0002] In the building materials, metallurgy, chemical industry and other industries, the powder or granular materials usually need to be bagged first and then loaded into trucks for shipment. Currently, the truck loading process is mostly still completed by manual labor. Manual truck loading not only has high labor intensity, but also produces a large amount of dust during the loading of some material packages, which seriously threatens the health of workers.

[0003] Although some automatic truck loaders have appeared now, such as the material package continuous automatic truck loading and stacking system disclosed in Chinese Patent No. CN108483052A, which can replace the manual truck loading system, be directly arranged downstream of the packaging machine production line, and be matched with the existing packaging machine station output to realize the continuous automatic truck loading and stacking of material packages. The inclined belt conveyor can realize forward and backward movement as well as up and down swinging, which to some extent meets the basic material conveying requirements, but cannot perform left and right yawing. This defect brings many inconveniences in actual application:

[0004] In a complex production environment, when it is necessary to accurately convey materials to different positions, the inclined belt conveyor that cannot yaw left and right cannot be flexibly handled. For example, in the cargo loading operation, the positions and sizes of truck compartments vary, and the existing inclined belt conveying line cannot adjust the left and right directions according to the specific positions of the compartments, which makes it difficult for the materials to accurately fall into the specified areas within the compartments, affecting the loading efficiency and stacking quality, and even may cause the materials to scatter.

[0005] In addition, in some production sites with compact workshop layout and limited space, the conveying line needs to have more flexible angle adjustment capability to avoid obstacles or work cooperatively with other equipment. However, the existing inclined belt conveying line cannot yaw left and right, which limits its application in complex spatial environments and increases the difficulty and cost of equipment layout.

[0006] When facing different production process requirements, this single-function inclined belt conveying line also seems to be inadequate. Some production processes require the materials to be switched to conveying directions at multiple angles during conveying to realize the classification, distribution and other operations of the materials. The existing inclined belt conveying line cannot meet such diversified process requirements, which restricts the optimization of production processes and the further improvement of production efficiency.
