Description

An automatic loading and unloading device for rolls of extremely thin metal strips

Technical field

The invention belongs to the technical field of production and processing of rolled metal strips, and specifically relates to an automatic loading and unloading device for rolled extremely thin metal strips.

Background technique

In metal rolling production, metal sheets are often rolled into strips. In order to facilitate the storage and transportation of metal strips, after the metal strips are processed on the assembly line, the metal strips are generally rolled into cylinders through a coiler. shape. In addition, when the rolled metal strip is processed into finished products in the downstream manufacturing industry, it is necessary to unwind the cylindrical rolled metal strip through an unwinding machine. In order to efficiently complete production and processing tasks, various industries often use crane hoisting to transfer rolled metal strips in actual production. However, this transfer method is not only limited by site space, but also requires manual assistance for operations. Therefore, this hoisting operation This method has the problems of site limitations and low transfer efficiency. At the same time, the overhead crane operation method not only has high initial construction investment costs, but also relatively high later maintenance costs.

In the existing technology, regarding the transportation scheme of rolled metal strips, the utility model patent with patent number CN202221511344.5 discloses a steel belt transportation rack for the production of direct plug-in LED brackets. This scheme is loaded on the transportation rack. When lifting steel strip coils, hang the hanging ring of the hanging frame on the hook of the electric hoist, use a "匚"-shaped frame to pass through the center hole of the steel strip coil, lift the steel strip coil, move it through the guide rail to the top of the placement slot, and then lift the steel strip coil. The steel strip coil is placed in the placement slot; when the steel strip coil is to be unloaded from the transport rack, the steel strip coil is lifted by the electric hoist and then moved outward along the guide rail to place the steel strip coil at the designated position. Although the solution disclosed in the above-mentioned patent realizes the batch transfer of rolled strips, in the process of placing the rolled strips on the trolley, an electric hoist is still used to lift the rolled metal strips. Whether it is a crane or an electric hoist, it is very easy for the rolled metal strip to slide out of the "匚"-shaped frame due to swinging during the lifting process. This will not only cause a safety accident, but also cause the rolled metal strip to be deformed and damaged. Therefore, This solution has a low safety factor and requires manual assistance.

At present, when the rolls of ultra-thin metal strips are hoisted using the above solution, in addition to the above problems, due to the excessive gravity of the rolls of ultra-thin metal strips and the low stiffness of the rolls, the lifting frame is easy to lift the rolls. The inner layer of the extremely thin strip of metal causes deformation damage. For the above reasons, the current hoisting operation method is not suitable for loading and unloading of extremely thin metal strips in rolls.
