A plurality of stoppers 5 that rotate using a cylinder via a rack and pinion mechanism (not shown) as a drive source are provided. During operation, the stopper 5 is in the upright state and is at the position indicated by the chain double-dashed line in the figure. A motor may be used as the drive source of the stopper 5.

A sub-stopper 5b is provided below the stopper 5 in the upright state. The sub stopper 5b is the contact surface 5
It is provided at a position such that bp is on the same plane as the contact surface 5p of the stopper 5 when standing up. A pusher 6 which is capable of advancing and retracting in the horizontal direction by an air cylinder 6a is provided facing the stopper 5. Stopper 5 and pusher 6
A table 7 that can be moved up and down by an air cylinder 7a is provided between them. The solid line position in the figure is table 7.
Is a normal position and is set to a height that does not interfere with the pusher 6. In the figure, the position indicated by the chain double-dashed line is the raised position of the table 7, P is the reference plane for positioning the plate w2,
It is perpendicular to the longitudinal direction of the plate material w1.

As shown in FIG. 6, the subframe sf
Is a plate material w2 perpendicular to the longitudinal direction at both ends of the upright plate material w1.
However, the surface material support member s is nailed perpendicularly to the surface portion of the plate material w1, and the sub-frame sf is one unit that constitutes the frame f.

When manufacturing the sub-frame sf, as shown in FIG. 7, the plate material w1 is first brought into contact with the sub-stopper 5b in an upright state at the working position A, and then the stopper 5 is raised. Since the contact surface of the sub stopper 5b and the contact surface of the stopper 5 are on the same plane, the plate material w1 is attached to the stopper 5
Also comes into contact. Then, the plate material w2 is brought into contact with the reference plane P, and the plate materials w1 and w2 are positioned.

After that, the table 7 is raised to the mounting position of the face material support member s, and the face material support member s is placed on the table 7 and positioned. Thereafter, the pusher 6 presses the face material support member s against the plate material w1 to fix the plate material w1 and the face material support member s.

Since it is not necessary to manually support the face material support member s, work efficiency is improved and safety is secured. Further, since the sub-frame sf, which is a structural unit of the frame f, is manufactured first, and when the frame f is manufactured, it suffices to combine the sub-frames sf according to the size of the frame f, so that work efficiency is improved.

In this embodiment, the table 7 is composed of four small tables 7s, and each small table has a cylinder 7b.
Are separately provided (see FIG. 3), each small table 7s can be independently moved up and down. Therefore, by selecting the table 7a to be lifted by operating the operation panel (not shown), the sub-frame sf can be manufactured even by using the plate material w1 and the face material supporting member s having different sizes.

Since it is not possible to abut the plate w2 on the end opposite to the reference plane P of No. 1 and nail it, the small table 7s is lowered after the nailing of all the face support members s, and the reference plane P Although the plate material w2 on the opposite side is nailed, the plate material w2 on the opposite side of the reference plane P is lifted even when the table 7 is raised by dividing the table 7 into finer parts so that the table 7 can be moved up and down.
Can be nailed, and it is possible to cope with a variety of sizes of the plate materials w1 and w2 and the face material support member s. When the small table 7s on the working position A side is in the lowered position, the control circuit locks the control circuit so that the small table on the pusher 6 side does not rise due to a malfunction of the control panel to ensure safety. .

Further, in the present embodiment, the air cylinder 7a of the table 7 has only one base stroke amount, and has only two states, that is, when the table 7 is lowered and when it is raised, and the height of the table 7 cannot be adjusted. However, if a cylinder having a plurality of strokes is used, the width of the plate material w1 changes,
Even if the height at which the face material support member s is positioned is changed, the face material support member s can be positioned.

Further, a plate 7c perpendicular to the table surface is provided on the side of the work position A of the table 7, and the space formed under the table surface is closed when the table 7 is lifted. Safety is assured without the operator having to stuff his fingers during the descent.
