Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile production automation, and in particular provides a cross-workshop three-dimensional conveying system for aluminum profile production. Background Art

[0002] With the rapid development of the national economy, the demand for aluminum profiles has increased rapidly, which has put forward higher requirements for the production automation of aluminum profiles.

[0003] During the production process of aluminum profiles using the extrusion process, they go through multiple links, including heating of raw aluminum bars, extrusion molding by extrusion molding machines, shaping and cooling, and storage in warehouses. At present, the transportation of aluminum profiles between processes and between workshops is generally completed by manually driving motor vehicles or manually operating cranes on the ground. Not only is the transportation efficiency low, the ground space is large, the transportation process is labor-intensive, and the bundling and hoisting are prone to damage to the aluminum profile surface. In addition, the transportation between each process is carried out separately, and it is impossible to coordinate and control it in a unified manner, making it difficult to meet the needs of automated continuous production. Summary of the invention

[0005] In order to achieve the above-mentioned purpose, the present invention provides a three-dimensional conveying system across workshops for aluminum profile production, comprising an upper conveying unit, a middle conveying unit, a lower conveying unit and a three-dimensional conveying control unit.

[0010] Furthermore, the lower conveying unit further comprises a longitudinal conveying trough connecting the longitudinally adjacent workshops, the longitudinal conveying trough passes under the middle transverse guide rail, the lower longitudinal guide rail is arranged at the bottom of the longitudinal conveying trough, and the lower conveying vehicle runs in the longitudinal conveying trough. The longitudinal conveying trough is arranged underground, which can save the floor space of the workshop and avoid mutual interference between the conveying process and the middle conveying vehicle of the middle conveying unit, which is conducive to the orderly three-dimensional conveying process.
