Description

Vehicles for loading and handling coiled material

technical field

The invention relates to the technical field of vehicles, in particular to a vehicle for loading and transporting coiled materials.

Background technique

In the process of cigarette production and packaging, a large amount of packaging materials are required, and most of the packaging materials used are materials with a package structure, which are large in size and heavy in weight. For example, the inner diameter of the stick-packed transparent paper reel of the cigarette production and packaging unit is at least 80 mm, its outer diameter is at least 280 mm, its transparent paper width is at least 336 mm, and its weight is at least 16 kg. In addition, the trademark auxiliary material of the cigarette production soft pack packaging unit is also reel type, its inner diameter is at least 150 mm, its outer diameter is at least 580 mm, its auxiliary material width is at least 100 mm, and its weight is at least 28 kg.

During the installation process of the coiled materials, it still needs to consume a lot of manpower for unloading and installation. Other technical solutions that can solve the lifting problem are also provided in the prior art, for example, directly using forklifts or fixed elevators to carry materials, but this method also has disadvantages, and the disadvantages are:

2. Since the coiled material is cylindrical and difficult to fix, the existing forklift arm and fixed lift are not suitable for handling and loading the coiled material. The existing forklift arm has a rectangular parallelepiped structure. If the cylindrical surface of the packaged material is pressed against the rectangular parallelepiped forklift arm, the packaged material is easily damaged. If the bottom surface of the coiled material is placed on the forklift arm or a fixed elevator, it needs to be manually moved before it can be further installed on other equipment, which is not conducive to the installation operation of the coiled material, resulting in very low efficiency.
