Description

Technical Field

[0001] The invention relates to the technical field of sorting and feeding bundled angle steels, and in particular to an automatic unstacking and feeding system for bundled angle steels. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel strip with two sides perpendicular to each other. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connectors between components. It is widely used in various building structures and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves, etc. Usually, the two sides of the angle steel are perpendicular and equal to each other. After production, multiple angle steels are generally stacked together. When reprocessing the angle steel, the bundles of angle steel need to be sorted, sorted and loaded.

[0003] At present, after the bundled angle steels are sorted and placed on the loading platform, the staff manually puts the angle steels to the next process. The manual loading method is inefficient and increases the burden on workers. Secondly, the angle steels are grabbed by a mechanical claw arm with a suction cup and then put into the next process. However, the angle steels are placed in multiple places on the loading platform, which means that the arm claw needs to detect the position of the angle steel before picking it up, resulting in an incoherent loading process.

[0004] After searching, the patent with announcement number CN115947101B discloses a device for separating and transferring angle steel feeding, which can ensure the safety of feeding, avoid the phenomenon of angle steel falling, and facilitate the separation operation of angle steel. However, it is difficult to perform destacking and sorting operations on the angle steel stacks with unified opening directions in the above scheme. The current angle steel stacks are formed by stacking multiple layers of angle steels, and each layer of angle steels is composed of multiple parallel angle steels, and the opening directions of the angle steels in two adjacent layers are opposite, that is, each layer of angle steels is staggered and stacked to form an angle steel stack. Each time the destacking and sorting machine grabs the angle steel and places it on the feeding platform, it is difficult to unify the opening direction of each angle steel. The inconsistent opening direction of each angle steel will affect the continuous feeding of subsequent processes, and the staff is required to manually rotate it to make the opening direction of each angle steel consistent, resulting in slow subsequent feeding efficiency and increasing the labor intensity of the staff. To this end, we provide an automatic destacking and feeding system for bundled angle steels. Summary of the invention

When the device grabs the angle steel with the opening facing upward, the picking wedge plate is controlled to extend from the rotating cylinder, so that the magnetic strip 2 on the picking wedge plate attracts the angle steel, and then the rotating cylinder is rotated to drive the angle steel with the opening facing upward to flip 180 degrees, and then the electric track 1 is controlled to drive the Y-shaped push block to push the angle steel to the conveying table, so that the angle steels grabbed by the device are placed on the conveying table with the opening facing downward.
