Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a plate stacking feeding device. Background Art

[0002] The feeding device is widely used in various types of production lines. At present, its process can be divided into two categories: automation and manual. Manual feeding, as the name implies, means that the product feeding process is completed by manual operation. This process not only has low production efficiency, but also manual operation is mixed with too many uncertain factors. For example, in terms of safe operation, according to the ability and working time of the operator, if the operator's skills are immature, the working time is too long, and operation accidents may occur. In addition, manual operation equipment has relatively high requirements for equipment and needs to set up comprehensive protection measures. On the one hand, it increases the cost of equipment, and on the other hand, many potential risk factors may not be taken into account. Therefore, there are many disadvantages of manual operation. Automated whole-stack feeding technology is currently in a stage of development, but none of them are too mature and cannot achieve the change of direction in the feeding process of sheet materials.
