As shown in the figure, the first finished box (B) is subjected to a post-process of round processing of the vertices by folding the base material, and the round process is performed as follows.

First, a seating step for seating the workpiece box B on the conveyor belt is preceded. In the seating step, the direction of the box (B) must be set and placed on the conveyor belt.

Next, when the box B, which is a workpiece, is moved along the conveyor belt, a corner portion of the box B is brought into contact with the round processing means 100. At this time, the height of the round processing means 100 is formed to be lower than the height of the vertex of the box B, and the left and right positions of the round processing means 100 are formed inside the vertex of the box B , The round processing means (100) presses the corner portion of the box (B).

In this state, when the box B is continuously moved along the conveyor belt, the round processing means 100 presses the vertex portion of the box B to perform round processing. More precisely, while the rotating body 140 of the round processing means 100 is rotated, the machining portion 145 of the rotating body 140 presses the corner point of the box B to perform the round processing step.

At this time, since the round processing means 100 is installed in an oblique direction so as to correspond to the vertex of the box B, it is possible to accurately press the corner portion of the box B, The box B can be prevented from being excessively depressed.

Since the height of the round processing means 100 can be adjusted by the actuator 110 connected to the round processing means 100, if the type or size of the box B is changed, Can be adjusted.

When the box B passes through the round processing means 100, the rounding of the corner point of the box B is completed and the position of the box B is rotated in the orthogonal direction, A resetting step may be followed.

In this state, the round processing means 100, or another round processing means 100 installed successively therethrough, may be performed to carry out the round processing of the remaining corners that have not been subjected to the round processing, that is, the second processing step.

Through such a process, the vertexes of the box B are automatically round-processed, and a plurality of boxes B can be round-processed through a continuous process.

Of course, as shown in FIG. 10, after the rounding of the corner point, the corner (BA) of the box B through the relative movement between the round processing means 100 and the box B moving on the conveyor, , BB) may be round-processed continuously.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
