Description

A cutting machine automatic feeding device and its control method

technical field

The invention relates to the technical field of cutting machinery, in particular to an automatic feeding device for a cutting machine used for material cutting and processing in industries such as shoemaking and leather goods processing.

Background technique

With the improvement of living standards, people have more and more diverse requirements for the styles and materials of shoes, leather goods and other products, which means that there are more and more types of related materials that need to be cut, and it is necessary to continuously improve the automation of cutting machines level to save labor and material costs and improve processing efficiency.

Shoemaking, bag making, etc. are generally made by stitching pieces of different shapes. The pieces of different shapes are obtained by cutting fabrics under the cutting machine by forming a knife mold. The fabrics to be cut can be leather, cloth, plastic, etc. , plastic paper and other materials. The cutting machine is a common equipment used for fabric cutting and processing. When working, the movable die base installed on the cutting machine is driven by power to move on the guide rail. After moving to the set position, it is installed on the die base. The knife mold presses down to cut the fabric, and cuts out the pieces that are consistent with the shape of the knife mold from the fabric, thus completing the blanking work. At present, there are generally two packaging forms for cutting materials, one is roll material and the other is wrap material. For the coil material, the coil material can be directly installed on the material shaft of the feeding platform behind the cutting machine, and the feeding mechanism can drive the material shaft to rotate and continuously feed and cut, with high efficiency. As for wrapping, the process is relatively more complicated. Wrapping means that the fabrics are stacked layer by layer. At the same time, some fabrics are relatively thin and need to be cut by stacking several sheets to improve efficiency. The problem is that there is no such device yet. The packaging materials can be sorted and prepared automatically to automatically feed the cutting machine. The current practice is that when the cutting machine is working, arrange workers to prepare materials next to the feeding platform behind the cutting machine, that is, manually take out a certain amount of packaging materials from the entire package. The fabrics are stacked neatly. After the cutting machine has cut a batch, the prepared pre-cut fabrics are placed on the feeding platform, and then the cutting is started. At the same time, there are many relatively thin materials among the materials that need to be cut at present. The materials are stacked together, and manual sorting is not easy. This manual material preparation method needs to be shut down every time the cutting is completed, and it cannot be cut continuously. The efficiency is low and the labor cost is high. Therefore, in order to improve efficiency, it is necessary to solve the problem that the packaging material cannot be automatically loaded.
