Description
技术领域technical field
本发明涉及一种空中料框输送系统,属于铝型材生产设备技术领域。The invention relates to an aerial material frame conveying system, which belongs to the technical field of aluminum profile production equipment.
背景技术Background technique
在铝型材挤压生产过程中,需要经过在线淬火、矫直、定尺锯切等工序,因而,每完成一个工序便需要将铝型材搬运到指定的位置进行下一个工序。铝型材搬运过程通常是先通过人工将待处理的铝型材搬运至料框内存放,然后再搬运料框来实现铝型材的搬运。目前厂内通常是通过行车和吊具来实现料框的搬运,这种方式长时间占用吊具,工人劳动强度大,搬运效率低下;另外行车吊装料框受车间内设备安装影响可能无法实现,或在吊运时会影响生产的顺利进行。In the extrusion production process of aluminum profiles, processes such as on-line quenching, straightening, and sawing to length are required. Therefore, every time a process is completed, the aluminum profile needs to be transported to a designated location for the next process. The aluminum profile handling process is usually to manually transport the aluminum profiles to be processed into the material frame for storage, and then move the material frame to realize the aluminum profile handling. At present, the material frame is usually transported by crane and spreader in the factory. This method occupies the spreader for a long time, the labor intensity of the workers is high, and the handling efficiency is low. In addition, the lifting of the material frame by the drive may not be possible due to the influence of equipment installation in the workshop. Or it will affect the smooth progress of production during lifting.
