In this embodiment, the base frame 30 and the transporting tools 20 and 20 attached to the base frame 30 form an inclined portion 5 that is bent downward with the downstream side as a fulcrum O.

The base frame 30 is provided with a receiving portion 6 for preventing the profiled material W conveyed by the second conveyor 13 from sliding down due to bending of the inclined portion 5. In the present embodiment, the receiving portion 6 is formed as a dock body that can return by gravity.

The first conveyor 12 is provided with a guide 7 fixed to a support piece 39 for supporting the driven shaft 26 and extending obliquely downward toward a discontinuous portion G of the conveyor in which the inclined portion 5 is bent. Provided. Therefore, when the discontinuous portion G is formed in the conveyor 2 due to the bending of the inclined portion 5, the profile W transported by the first conveyor 12 is guided by the guide 7 and falls.

Further, the guide 7 is provided with a small height locking piece 9 for changing the posture of the falling profile member W.

Next, a method of engaging and transferring the profile W will be described. (1) The preceding profile W1 carried in with the groove 4 facing upward by the carry-in conveyor 23 is directed to the first conveyor 12 by the pusher 24 with its longitudinal axis orthogonal to the carrying direction and the groove 4 facing upward. Will be transferred. Note that the second conveyor 1

(3) The inclined portion 5 of the second conveyor 13 is bent as shown by a chain line in FIG.
A break G is formed on the downstream side of. The profile member W1 on the second conveyor 13 receives the sliding portion 6 due to the bending of the inclined portion 5 and the receiving portion 6.
And thus the preceding section W1 is held in place.

(4) The succeeding profile W2 is conveyed on the first conveyor 12 with the groove 4 upward as shown in FIG. 3, similarly to the preceding profile W1. However, due to the formation of the discontinuity G as shown in FIG. 4, the succeeding profile W2 falls along the guide 7.

The profile material W2 that falls along the guide 7 and follows
As shown by an alternate long and short dash line in FIG. 4, the groove 4 is turned downward by contacting the locking piece 9, and falls on the preceding profile W 1, thereby forming the groove of the preceding profile W 1. A mating pair F is formed by inserting one of the flange portions 3 of the succeeding profile member W2 into the mesh member 4 and meshing with each other.

(5) After that, the inclined members 5 are returned to the horizontal position, and the second and third conveyors 13 and 14 are driven so that the profiles W1 and W2 maintain the posture of the meshing pair F. Then, it is sent from the second conveyor 13 to the unloading conveyor 27 via the third conveyor 14.

In the present invention, the workpiece W can also be adopted for an I-shaped member as long as the flanges 3, 3 are present across the groove 4. In addition, the conveyor 2 can be formed as a belt conveyor as the conveying tool, and a roller conveyor with a forced drive can be employed. Further, the conveyors 20, 20 of the second conveyor 13 having the inclined portion may be formed to be driven and stopped separately from the third conveyor 14. In addition, a rubber plate or the like may be interposed in order to reduce an impact generated when the shaped material W2 following the inclined portion 4 of the second conveyor reversely falls. As described above, the present invention can be modified into various aspects.

[0030]

As described above, according to the method of the present invention, the step of bending and returning the part being conveyed while resting the part being conveyed on a part of the conveyor, as described in claim 1, engages the parts. Therefore, the tact time of the meshing operation is short, and the productivity can be improved.

In addition, since a special structure is not required for reversing the shape material and the structure is simple, maintenance is easy,
In addition, malfunction can be prevented, and the danger of device failure can be eliminated.

Further, when the succeeding profile is dropped by the guide of the guide and is inverted by the locking piece provided on the guide, the subsequent profile can be dropped smoothly. In addition, it is possible to reduce malfunctions and to prevent deformation of the profile due to the impact of the subsequent drop of the profile. Further, the succeeding profile can be surely inverted by the locking piece, and the danger of malfunction can be more reliably prevented.

Further, as described in the third aspect, the preceding section is prevented by the slip-down receiving section caused by the refraction of the inclined section, so that the following section drops when meshing with the following section. The impact force generated at that time can prevent the engagement pair from being detached from the conveyor, and can prevent malfunction from occurring.
