Thus, all works can be done automatically in a predetermined procedure and timing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a systemized wood processing device that cuts a workpiece into a predetermined shape using a woodworking router.

[Conventional technology]

When cutting a workpiece using a woodworking router using numerical control, it is necessary to fix the workpiece on a table, and vacuum suction is known as a means for fixing the workpiece. Conventional vacuum suction means have multiple suction holes on a table, connect this table to a vacuum pump, and place a jig plate with suction holes that match the shape of the workpiece on the table. Then, by operating the vacuum pump with the workpiece placed on this jig plate, the workpiece on the jig plate is placed in a predetermined position along with this jig plate through each suction hole. It is fixed by suction.

For this purpose, many jig plates are prepared according to the size and shape of the workpiece, and these are used selectively. In addition, the necessary jig plates are selected from the stocker where the jig plates are stored and managed, transported to the table, and then positioned on the table, and the workpiece after cutting is carried out. The reality is that most of the work, such as taking the products out of the table and transporting them to the next process, relies on manual labor.

[Problem to be Solved by the Invention J] As mentioned above, conventional wood processing requires a large number of people because many tasks other than cutting the workpiece are performed manually. , since many jig plates are used,
There were problems such as easy work errors such as wrong selection of jig plates (and poor work efficiency).

This invention was made in order to solve the above-mentioned problems, and the purpose is to provide a systemized wood processing device that can automatically perform all the above-mentioned operations in a predetermined procedure and timing. It is said that

[Means for Solving the Problems] A wood processing device according to the present invention is based on a robot device that carries out a specified workpiece from a woodworking router, and a table provided with suction fixing means including a jig plate.

[Operation J] The wood processing device of the present invention automatically selects and carries out a specified workpiece from a woodworking router, and
The unloaded workpiece is automatically placed on the table, and then cutting is performed. After the machining is completed, the workpiece is automatically unloaded, and treatment is performed according to the specified workpiece. A tool plate is automatically selected and carried out from the jig plate stocker, replaced with the previously used jig plate, and placed on the table.
