DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, a predetermined length of a precut material such as a horizontal member is inspected to determine whether or not a predetermined process is accurately performed at each processing position. A plurality of frame members are mounted on the side of the conveyor corresponding to the processing positions of the above, and upper laser generators are installed on the upper portions of the frame members so as to irradiate the center of the processing position of the pre-cut processing material. By installing a stopper at the transport end of the transport conveyor, the pre-cut workpiece is transported on the transport conveyor, and when the tip of the pre-cut workpiece hits the stopper, laser beams are emitted from multiple upper laser generators at once, By observing whether or not the laser beam crosses the center of each processing position of the precut material, each processing of the precut material is correct. That it has been subjected to can be inspected at once.

FIG. 4 is an enlarged side view of the pre-cut work material inspection apparatus shown in FIG. 1. The conveyor 10 is divided into a plurality (six in FIG. A stopper 13 is provided at the end of the conveyance, and an interval 11 is provided at a position corresponding to the processing position of the long precut processing material.
And the frame members 14 are respectively installed behind the gaps, and the arm members 1 protruding from the upper portions of the frame members 14 respectively.
5 project from the conveyor 10 forward, and upper laser generators 16 are attached to the respective ends of the arm members 15.

In the inspection apparatus for a precut material according to the present embodiment, the precut material 1 shown in FIG. 8 is carried in from the conveyor 10 and is conveyed until the tip of the precut material 1 hits the stopper 13. When the stopper 13 is hit, the laser beam 16a is emitted from all of the upper laser generator 16 to the precut material 1, but these laser beams 16a are emitted through the centers of the respective processing positions of the precut material. With such adjustment, whether or not each processing position of the pre-cut processing material 1 is accurate is visually confirmed by the position where the laser beam is applied.

In the precut material inspection apparatus according to the present embodiment, the precut material 1
Then, the laser beam is emitted from the upper laser generator 16 to all the processing positions of the pre-cut workpiece at the transport position so that the processing of the pre-cut workpiece 1 is accurately performed at a predetermined position. Can be checked at once.

In the above embodiment, an example is shown in which six upper laser generators 16 are provided. However, the upper laser generator 16 may be increased and changed according to the number of processing positions of the precut workpiece 1. Alternatively, the upper laser generator 16 is moved within the range of the arm member 15 so that the upper laser generator 16 is moved to two adjacent processing positions of the pre-cut workpiece 1 between the appropriate intervals 11. May be simultaneously irradiated with the laser beam 16a.

In the above embodiment, only the upper surface and the front surface of the precut material 1 can be inspected by the upper laser generator 16, but the rear surface and the lower surface cannot be inspected. Inspection may be performed by exchanging the upper and lower sides, or the rear surface and lower side of the precut workpiece 1 after the conveyor 12 may be irradiated with a laser beam by another laser generator.

FIG. 5 is a front view of an apparatus for inspecting a precut material according to another embodiment, FIG. 6 is an enlarged front view of the apparatus for inspecting a precut material of FIG. 5, and FIG. 7 is an apparatus for inspecting the precut material of FIG. 10 is a conveyor, 11 is an appropriate interval, 12 is a conveyor, 13 is a stopper, 14 is a frame member, 15 is an arm member, and 16 is an upper laser generator. Although the description is omitted because it is the same as the example, in this embodiment, a lower laser generator 17 for irradiating a laser beam to the lower surface and the rear surface of the precut material 1 is attached to each frame material 14. A reflector 18 for reflecting the rear surface of the pre-cut material 1 is mounted on the upper part of the mirror, and a reflector 19 for reflecting the lower surface of the pre-cut material 1 is mounted below an appropriate interval 11.

In the inspection apparatus for a precut material according to the present embodiment configured as described above, when the tip of the precut material 1 is conveyed to contact with the stopper 13, the upper laser generator 16 removes the precut material 1. The front and top surfaces are illuminated, and the precut material 1 is
Since the rear surface and the lower surface are illuminated, the processing positions of the upper surface and the front surface of the precut material 1 can be confirmed by the laser beam from the upper laser generator 16,
In addition, the inspector stands on the front of the precut material 1 by reflecting the laser beams from the lower laser generator 17 on the rear and lower surfaces of the precut material 1 by reflecting them on the reflecting mirrors 18 and 19. The processing positions of the front and rear surfaces and the upper and lower surfaces of the pre-cut material 1 can be confirmed up to this point.

In this embodiment, as described above, by providing the upper laser generator 16, the lower laser generator 17, and the reflecting mirrors 18 and 19, the precut material 1
It is possible to easily inspect whether the processing positions of the upper and lower surfaces and the front and rear surfaces are not shifted.

Although the above embodiment shows an example in which six lower laser generators 17 are provided, the lower laser generator 17 is provided in accordance with the number of processing positions of the pre-cut workpiece 1 as in the case of the upper laser generator 16. Alternatively, it may move within the range of the arm member 15 similarly to the upper laser generator 16.

[0015]

As described above, in the pre-cut material inspection apparatus of the present invention, the pre-cut material is transported to the end of the transport conveyor until it comes into contact with the stopper, and the pre-cut material is irradiated with the laser beam from the upper laser generator. It is possible to inspect at once by irradiating the respective processing positions of the front and upper surfaces of the workpiece at once, and also to process the rear and lower surfaces of the pre-cut processed material with the laser beam from the lower laser generator and two reflecting mirrors, respectively. There is the advantage that the position can be checked at once.
