Description

Technical Field

[0001] The invention relates to the technical field of furniture edge banding, and in particular to a control system and a control method of a soft forming edge banding machine. Background Art

[0002] The automatic edge banding machine is a key mechanical equipment used to process panels in furniture manufacturing factories, and its various components demonstrate a high degree of automation performance.

[0003] In the current market, with the growing demand of consumers for personalized furniture, the types of custom-made furniture are showing a trend of diversification. Each batch of orders often contains boards of different sizes and shapes, which undoubtedly puts forward more complex and delicate requirements for edge banding. Traditional edge banding methods seem to be unable to cope with these diverse boards. In particular, the application scope of special-shaped edge banding machines on the market is severely limited, and they can usually only meet the needs of forming edge banding of a single shape. What is even more inconvenient is that before performing edge banding operations, such machines often require manual debugging and calibration of the tool, which undoubtedly increases the complexity and time cost of the operation.

[0004] When it is necessary to edge band other shapes of plates, the existing special-shaped edge banding machines are even more inadequate because at this time, all parts of the entire edge banding machine need to be re-debugged and reconfigured, which is not only time-consuming and labor-intensive, but also greatly reduces production efficiency.

[0005] In view of the above situation, in-depth improvement and innovation of existing edge banding technology to adapt to changes in market demand has become an urgent issue to be solved in the industry.
