Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a frame material processing device that can automatically cut a frame material and perform tenon processing.

[Background technology]

For example, in buildings such as houses, various frame materials are employed. In addition, especially in buildings using the dry construction method, as shown in Figure 5, frame members a made of channel steel are used.
A construction panel P is constructed by spanning a wooden frame material W, for example, within a framework F with its grooves facing inward.
However, it is often used for walls, roofs, and especially floors.

On the other hand, in such a frame material W, it is necessary to provide tenons b corresponding to the thickness of the frame material a on both sides at both ends that fit into the grooves, and conventionally, such processing was performed sequentially using a tenon removing machine. Since this was done manually, the productivity and processing accuracy of the frame material was poor.

[Purpose of the invention]

The present invention can solve the above-mentioned problems by integrally linking a cutting tool and a tenon removal machine, and by making it possible to perform cutting and tenon processing of frame materials in a series.

A driving machine 35 is installed which can move up and down and rotate the through hole c.

The input conveyor 2 has a side wall 1 at its inner end.
Each pair of guide pieces 37 and 38 extend toward 6.
are provided protrudingly inside the positioning tools 3 and 4, respectively, and the guide pieces 37 and 38 are cut near the side wall 16.
Opposite guide pieces 39 and 40 are formed at the same position as 8 with a gap G having the same width as the frame material W.

The transverse feeder 6 is provided parallel to the guide pieces 37 and 38.

As schematically shown in FIG. 2, the lateral feeders 6 are disposed on both sides of the punching machine 11 and on the upstream side of the punching machine 12, and the crossfeeders 6 direct the rod toward the side wall 15 and direct the rod toward the side wall 15.

Grips 7 and 8 are attached to the cut ends of the guide pieces 37 and 38. The gripping tool 7 is provided on the extension line of the guide 46, and the gripping tool 8 is provided on the extension line of the cutting tool 5.
installed in the horizontal direction.

In the gripping tools 7 and 8, an elevating cylinder 52 is attached to the opposing upper pieces of a substantially Z-shaped base frame 51 with the rod downward, and a U-shaped frame 54 is fixed to the lower end thereof with the grooves facing each other. The U-shaped frame 54 has horizontal upper and lower pieces 56 and 57 above and below the side pieces 55, respectively. The upper piece 56 is formed longer than the lower piece 57,
The upper piece 56 is connected to the rod of the elevating cylinder 52, and a guide shaft 59 for loosely inserting the upper piece of the base frame 51 is provided on the upper piece 56 to prevent rotation. Further, a pressing tool 61 having a pressing piece 60 at the lower end is attached to the lower surface of the upper piece 56, and the gripping tools 7 and 8 are

The base frame 51 is fixed via a support frame 64 onto a movable table 63 that moves along the side wall 16. Note that the movable table 63 runs on a rail 67 laid on the bottom plate 14 of the pedestal 17. In addition, as the elongated cylinder 69 whose rod end is fixed to the movable table 63 expands and contracts, the frame material W positioned by the positioning tool 3 is moved from a position where it can be inserted near the side piece 55 by the positioning tool 4. It can reciprocate to a position where the positioned frame material W is guided to the vicinity of the side plate 55 thereof.

Note that the U-shaped frame 54 is formed narrower than the frame material W.

The tenon removing machines 9 and 10 are disposed below the gripping tools 7 and 8, and the tenon removing machine 9 can process the tenons b and b on both sides of one end of the descending frame material W. The removing machine 10 can perform tenon processing on both sides of the other end of the frame material W.

Thereafter, the gripping tools 7 and 8 extend the lifting cylinder 52 and lower the frame material W gripped by the pressing tool 61, thereby lowering the tenon removal machines 9 and 10 as shown in FIG. Katsuta 9a, 10a
Both ends are tenoned at the same time to form tenons b. Thereafter, the grippers 7 and 8 are pulled up and the lifting cylinder 52 is contracted to release the grip on the processed frame material W, and the positioning piece 42 is lowered. Further, by the next operation of the horizontal feeder 6, the frame material W1 that has not yet been tenon-processed is laterally fed to the position of the gripping tools 7 and 8, so that the frame material W that has been processed is By extruding the unfinished frame material W1, the opposite guide pieces 39 and 4 are
0 and taken out from the device by hand or using a carrying tool (not shown).

In addition, in order to manufacture a long frame material W, the cylinder 6
