Then, the plate materials are positioned by a pusher 28 and are then allowed to travel in the orthogonal direction so that the leading end edges thereof are chamfered by means of a chamfering machine 25 in a fourth sander section (U). Thus, it is possible to chamfer the peripheral edges of the plate materials, efficiently and rapidly, with a high quality process.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic multi-sided chamfering device for plate materials. This invention relates to an automatic multi-sided chamfering device that cuts off corners.

(Prior art) A conventional board chamfering device manually supplies each peripheral edge of the board to a grinder such as a belt grinder, air or electric Pelton, and removes chamfering by scraping off the corners of the board's periphery. It was the mainstream.

(Problems to be Solved by the Invention) In chamfering work using a conventional board chamfering device, each peripheral edge of the board is fed to a grinding machine section while changing the orientation of the board manually. However, the processing efficiency of the plate material is low, and the quality of the chamfering largely depends on the skill of the worker, making it difficult to obtain uniform quality. There are many points that need to be improved in terms of floor safety.The present invention solves the above-mentioned problems inherent in the conventional chamfering device, and automatically feeds the chamfering machine sequentially to the chamfering line. The object of the present invention is to provide an automatic multi-sided chamfering device capable of self-propelled and sequentially supplying predetermined peripheral edges of the plate to a chamfering machine, and capable of uniformly chamfering work in a series of flow processes.

(Means for Solving the Problems) In order to achieve this object, the present invention has the following configuration. That is, in the automatic multi-chamfering device for plate material according to the present invention, the traveling path of the plate material, which is equipped with a holding mechanism and a transfer mechanism for the plate material in the same direction, extends in a straight path and in a different direction that intersects the straight path. It is constructed in combination with an intersection path, and each of these paths is characterized in that a chamfering machine is installed at the position where the peripheral edge of the plate material on one side of each path runs.

(Function) On the traveling path formed by the combination of a straight path and an intersection that intersects the straight path, sheet materials are carried in one by one. While the board is running on a straight path, a chamfering machine installed on each side edge of the road is used to chamfer the edges on both sides.Then, while maintaining the same direction, the board is chamfered at an intersection leading to the straight path. There, the edge of one side of the board is cut, and then, as the board continues to travel in the same direction on the straight road following this intersection, the edges of the other side of the board are cut, and then the edges of the other side of the board are Next, the edges of the other side of the plates traveling in the same direction on the intersection path are sequentially chamfered, and in the process of the plates completing the entire traveling path, the chamfering work on the peripheral edge of the plates is completed.

(Example) Next, a specific example of the automatic chamfering device for plate materials according to the present invention will be described with reference to the drawings.

Figure 1 is a schematic plan view of this device, with the control box (2) as the reference position, and the directions of movement of the board (1) on the running path: right on a straight path, forward on an intersection path, and right again on a straight path. , In each process of backward movement on the intersection, the plate material (1)
The chamfering operation proceeds in the order of the front edge (IA), rear edge (IB), rear edge (IC), and front edge (ID) of the board.

On the left side of the control box (2) is an automatic lifter (
3) is arranged, and this lifter (3) and a plurality of suction cups (4
) (4) is attached to form a carrier part (2) with a carrying machine (5) which is movable in the earthwork direction and in the front-back direction. There are multiple plates (
1) are stacked in an orderly manner with the help of several frames (6). A loading machine (
The suction cup (4) (4) of 5) descends, attracts the - piece of board (1), rises, then moves forward, and further descends to release the adsorbed board (1) and chamfer it. Table (8)
(See Figure 2).

The front edge of the chamfering table (8) on which the reference wall (9) is erected is tilted downward, and the board (1) carried onto the chamfering table (8) slides under its own weight. The front edge (IA) of the plate material (1) is brought into contact with the reference wall (9).

The plate material (1) of the chamfering table (8) that forms this straight path
) has a long groove aυ opened in the longitudinal direction that corresponds to the running direction of the plate material, and a part of the circulating endless chain α■ is inserted into the long groove αυ, and the chain θ is inserted into the long groove αυ. The push claws α→ protruding at a predetermined pitch are attached to the table (
8) Protruding from f, the rear edge (IB) with the pressing claw
The plate material (1) runs to the right on the chamfering table (8) while being pushed by the part, and in this traveling process, the plate material (
The front (ILM (IA) part of 1) is always pressed with spring force against the reference wall (9) side that constitutes the chamfering table (8) by means of a lateral pressure roller αη. In order to prevent the traveling plate (1) from floating above the running surface OQ, the upper surface of the plate (1) is held down by two upper pressure bars θ, and the plate (1) is thus pressed against the reference wall (9). The front edge (IA) portion is brought into sliding contact with the vehicle as it runs.
