Description

Technical Field

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of profile processing, angle brackets are used as connecting components, and their access process has a significant impact on production efficiency and quality. In the existing technology, there are many problems in the access of angle brackets: on the one hand, traditional angle bracket access equipment mostly uses single-station silos, which can only accommodate a small number of angle brackets. Once the angle brackets in the silo are exhausted, the equipment has to shut down and wait for the silo to be replaced, frequently interrupting the production process. This not only leads to a significant reduction in production efficiency, but also causes the equipment to idle and waste energy during downtime, and also increases the overall production cost; on the other hand, since the existing angle bracket silos are single-station silos, the material taking mechanism structure of the angle bracket access equipment is fixed. When facing multi-station silos, it is difficult to accurately and quickly locate the angle bracket storage position, and the material taking efficiency is low. Faced with complex and changeable production needs, it is impossible to flexibly adjust the material taking action, which seriously restricts the smoothness of the production process.
