Ｒだけ移動して穿孔することができる。 Next, the relative positions of the second stopper 63, each machining unit A, C, D, E, and the workpiece W will be explained using the example of the horizontal member O shown in FIG. 6. The distance P1 between the stud notches g1 to g1 cut by the side processing unit C and the column rest h2 or large dovetail hook h1 cut by the side processing unit C is almost constant for various horizontal members O, and is actually 1.5 shaku. 2×P1 or 3
The shaku is generally the basic column spacing. In addition, both end surfaces O1 and O2 of the horizontal member O, and stud notches g1 and g1 at both ends.
The distances l1 and l2 between the two ends are indefinite values that vary depending on the shape of the joints at both ends of the horizontal member O. The second stopper 63, whose movement is controlled according to the machining at each position, moves l1+ to the circular saw 5 when cutting the entire length.
It is set at the position of 4×P1+l2 (=LA),
When machining the column support h2, l1 + P1 (=LD) with respect to the blade center line C1 of the side machining unit C,

They are set at positions S and l1+3×P1+T, respectively. Note that the counterbore bolt hole m1 and the flint bolt m2 are made by moving the counterbore drill 28 by Q and R in the X-axis direction with the workpiece W leaning against the column and set at the machining position h2 and flint carving j2, respectively. It can be perforated.

を規定するために右動端へ復帰して待機する。 Now, when cutting the horizontal member O, first place the workpiece W on the feed conveyor 70, transfer it to the left until the front end surface of the workpiece W comes into contact with the first stopper 7, After cutting near the front end of the workpiece W and scraping the reference end surface O1 of the horizontal member O, the first stopper 7 is retracted from the transfer path F. On the other hand, while cutting the second stopper 63 at each position to be processed into the workpiece W, the cutting is performed at the shortest position from the reference end face O1 first, and then the cutting is repeated at positions sequentially further away from the reference end face O1. In order to do this, the workpiece W is moved to the left until it comes into contact with the second stopper 63 while waiting in advance at the rightmost position of the movement stroke, and at this position, each vise 67 is activated to clamp the workpiece W. After that, move to a predetermined processing station (in this example, the first processing station S).
In step 1), the first cutting process is performed. Furthermore, the first
When the first cutting process is completed, the workpiece W is unclamped and moved to the left for the next cutting process. In order to define the next cutting position of the workpiece W, the workpiece W is moved to the left and the second It comes into contact with the stopper 63 again, is clamped by the vise 67, and the cutting process on the workpiece W is repeated at a predetermined processing station. Then, when all the cutting operations are completed by repeating the above series of operations, the workpiece W is carried out from the delivery conveyor 71, and the second stopper 63 sets the first cutting operation position for the workpiece to be subsequently machined. Return to the right moving end and wait for the specified conditions.

Second stopper 63
The movement control eliminates the need for smearing work,
Moreover, it has the effect of improving processing accuracy.

効果がある。 In the above cutting process, in this example, the distance between the blade center lines C1 and D1, and the distance between the blade center lines D1,
Since the interval E1 is set to a multiple of 1/2 of the basic column interval 2 x P1, the second stopper 63 is moved from the blade center line C1 to l1 for machining the large dovetail hook h1.
When set to +3 x P1 position, stud gap g1
Since it is sufficient to cut the mortise hole i1 at the position l1 (LE) from the reference end surface O1, and the mortise hole i1 at the position l1+P1 (LD), it is necessary to cut the large dovetail h1 and the stud notch g1 without moving the second stopper 63. , mortise hole i1 can be processed simultaneously by each processing unit C, D, and E. That is, in general, in a horizontal frame material for wooden construction, a mortise hole i is bored at a position of 2×P1 to the left of the large dovetail h, and
A combination of machining positions where the stud notch g is cut at the position is often used, and this combination has the effect of reducing the required number of machining operations for a horizontal member and making the cutting work more efficient.

ことができる。 Also, in Figure 6, 3 x P2 = 2 x P1, that is, P2 = 2/3P1, but generally P1 = P
2 is often the case, and in this case, the positions of the joist carving j1 and the stud notch g1 match, so cutting can be performed at even more positions at the same time, reducing the number of times of machining, the time required for machining, and the number of times the workpiece is transferred. etc., and the processing process can be streamlined and streamlined.
