In the wood supply device 12 thus constructed, a plurality of the first woods 5 are put into the first supply section 13 and a plurality of the second woods 6 are put into the second supply section 14, respectively. To be done. First, the first wood 5 at the tip of the first supply unit 13 is pushed upward by the push-up cylinder 27 of the first cutting mechanism 15, and then the main traverse cylinder 53 makes the first wood 5 in the protruding state. It is fed laterally until it comes into contact with the fall prevention pin 54.

Next, the second end of the second supply section 14
The wood 6 is changed from horizontal to vertical by the rotation of the rotary plate 38, and by releasing the stopper pin 40, the first wood 5 on the mounting table 52 and the pressing bar 58 of the main horizontal feed cylinder 53 are separated. To fall. At this time, the pressing bar 58 of the main traverse cylinder is retracted, leaving a space on the mounting table 52 between the first wood 5 and the second wood 6 to enter.

Finally, with the pressing bar 58 of the main traverse cylinder 53 returned to the original position, the first wood piece 5 is cut out again, and when the three pieces are aligned in the double stud group, the rear pressing mechanism 56. The rear ends are aligned by. Next, the fall prevention pin 54 is raised, and the auxiliary lateral feed cylinder 57
Comes and picks up the main traverse cylinder 53, and transfers the wood (double stud) 7A in the assembled state from the mounting table 52 to the supply conveyor 11 of the processing apparatus 10. By such a cycle, the timber 7A in the assembled state is sequentially assembled and supplied to the supply conveyor 11 of the processing apparatus 10.

The timber 7A in the assembled state supplied onto the supply conveyor 11 is conveyed to the position of the processing device 10 with its rear end aligned by the rear end jig 66, and at that time, the positioning mechanism 6
The tip of the second wooden piece 6 between both the first wooden pieces 5 is locked by the protruding positioning pin 69 of 7, and the second wooden piece 6 is positioned at a predetermined position from the tip of the first wooden piece 1. Then, the timber 7A in the assembled state is pressed by the upper pressing mechanism 65 and nailed by the automatic nailing machine 64,
It is carried out from the processing device 10.

As described above, according to the above-mentioned wood supply device 12, the first supply part 13 which horizontally supports and laterally feeds the plurality of first woods 5, and the first supply part 13 is provided above the first supply part 13. From the second supply unit 14 that horizontally supports and feeds a plurality of two pieces of wood 6, the first and second supply units 13,
The first and second cutting mechanisms 15 and 16 provided at the carry-out end of 14 respectively cut out the first and second woods 5 and 6 in order to sandwich the second wood 6 between the pair of first woods 5. The timber 7A in the assembled state is processed into the processing device 10
It is transferred by the transfer mechanism 17 to the supply conveyor 11 of FIG.
Therefore, the timber can be automatically assembled into a predetermined assembled state and continuously supplied to the processing apparatus 100, the operating rate of the processing apparatus 10 can be improved, and the productivity is improved.

Further, the second feeding portion 14 is formed so as to be inclined so as to laterally feed the second lumber 6 by its own weight, and the second cutting portion 16 cuts the second lumber 6 from the carry-out end and drops it. Since the plate 38 is provided, the structure of the second supply unit 14 can be simplified. Further, since the processing apparatus 10 has the positioning mechanism 67 for positioning the second wooden piece 6 in the assembled wooden piece 7A at a predetermined position from the tip of the first wooden piece 5, the processing accuracy can be improved. .

On the other hand, when supplying timber in a set state called triple stud, the second supplying section 14 is not used,
As shown in FIG. 7, a plurality of sets (7 sets in the illustrated example) of the first wood 5, the third wood 8 which is a medium-sized wood, and the first wood 5 are arranged and stocked in the first supply unit 13 in the order of a combination set. . First, the first lumber 5 is cut out and fed laterally to the fall prevention pin 54 by the main traverse feed cylinder 53, then the third lumber 8 is similarly cut out and fed laterally, and finally the first lumber
When the timber 5 is cut out, the rear end is aligned by the rear pressing mechanism 56 when the three pieces are aligned in the triple stud assembly.
Next, the tipping prevention pin 54 rises, the sub-transverse feed cylinder 57 comes to pick it up, and sandwiches it with the main traverse feed cylinder 53.
2 is transferred from above onto the supply conveyor 11 of the processing apparatus 10.

As described above, according to the above-mentioned wood supply device 12, it is possible to switch and supply two kinds of wood, that is, double studs and triple studs. Moreover, since it is not necessary to change jigs for switching, loss time can be reduced and productivity can be improved.

The embodiments of the present invention have been described in detail above with reference to the drawings. However, the specific configuration is not limited to the above-mentioned embodiments, and changes in design within the scope not departing from the gist of the present invention are possible. Even if it exists, it is included in the present invention. For example, in the second supply unit, rollers may be provided in the upper portion of the support frame instead of the top roller chain, or only an inclined support frame may be used as long as the second wood can be laterally fed by its own weight.
