Description

Technical Field

[0001] The invention relates to the field of woodworking machinery processing center technology, in particular to a control method for a cutting and connecting machine for loading materials with a single feed port. Background Art

[0002] With the emergence of microprocessors, the world has entered a new era of numerical control. The rapid rise of multi-axis controlled machine tools that can only be realized by computers has brought wood processing into an era of automation and intelligence. The application of numerical control wood processing centers in the field of wood processing is becoming more and more common. In the existing technology, numerical control wood processing centers can complete processes such as milling, vertical drilling or grooving. With the help of wood processing centers, wood can be processed conveniently and production efficiency can be improved.

[0003] Since wood needs to be processed in various ways before it can be produced as a finished product, in addition to the wood processing center, other production processes are also required to process the wood, such as labeling and cutting. Therefore, a flexible woodworking production line is formed for labeling and cutting a piece of wood. The existing flexible woodworking production line for wood labeling and cutting processing usually includes a feed port, a pile of plate loading roller machine, a labeling machine, and two cutting processing centers. Since it only has a single feed port, a pile of plate loading roller machine and a labeling machine, it is necessary to load the piles of plates to the two cutting processing centers in batches, that is, only one pile of plates can be put in at a time, and it is impossible to label the two piles of plates synchronously and then load them to the two cutting processing centers. This will increase the frequency of manual loading and affect work efficiency and labeling efficiency.

[0004] Therefore, it is necessary to develop a new technical solution to solve the above problems. Summary of the invention

[0005] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a control method for a cutting and connecting machine for loading materials from stacks of plates with a single feeding port, which can hold two stacks of plates at a time and two labeling machines can work at the same time, greatly reducing the frequency of manual loading and improving work efficiency and labeling efficiency.
