Next, the operation of the formed steel sheet stacking apparatus 1 of the present invention having the above-described configuration will be described.

First, before use, the elevating arm 31 of the support device 3 is raised in advance to the operation start position close to the support arm 8 and kept in standby. When a forming machine (not shown) is operated in this state, the formed steel sheet S formed into a predetermined shape by the forming machine is extruded from the outlet of the forming machine to the stacking device 1 side. At this time, since the left and right support arms 8, 8 of the stacking device 1 are at positions protruding inward of the frame 2 so as to face each other, the formed steel sheet S is pushed out onto the support arms 8, 8, and It is held as shown in FIG.
When the extrusion of the formed steel sheet S having a predetermined length is completed, this state is sensed by a sensor (not shown) or the like, and the cylinder device 9 of the drive mechanism 15 operates. The connecting member 10 driven by the cylinder device 9 includes a support arm 8,
Left and right longitudinal axes 6 and 6 to which the reference numeral 8 is attached are connected via a rack and pinion mechanism (not shown) arranged in the cover 11 and supported by a thrust bearing 7 so as to be rotatable. 6, 6 are rotated in opposite directions. Therefore, when the drive mechanism 15 operates, the left and right support arms 8, 8 move in a direction away from each other. As a result, the formed steel plate S supported by the support arms 8, 8 loses its support, and the lift arm 31
Fall on. When the drop is completed, the drive mechanism of the support arm 8 operates in a completely opposite manner to the above, and
To the original position to prepare for the next extrusion of the formed steel sheet S. At the same time, the elevating arm 31 of the support device 3 is lowered by the thickness of the formed formed steel sheet S to prepare for the next drop of the formed steel sheet S.

The formed steel sheet S extruded from the forming machine falls by a certain small head by the movement of the lifting arm 31, and is sequentially stacked on the lifting arm 31. And when this stack reaches a certain number,
The elevating arm 31 moves below the upper end position of the roller conveyor 4 and places the supported formed steel plate S on the rollers 42 of the roller conveyor 4. At this time, the formed steel sheet S is formed into a corrugated shape as illustrated,
If it cannot be movably supported by the roller conveyor 4,
Plate pieces B for support are provided at several places on the roller conveyor 4 in advance.
Should be put.

When the laminated formed steel sheet S is placed on the roller conveyor 4 in this manner, the double-acting cylinder 53 of the extruder 5 is operated, and the frame 51 movably placed on the rail 12 is moved. Extrude. As a result, the extruded surface 51a provided at the rear end of the frame 51 comes into contact with the end surface of the laminated formed steel sheet S placed on the roller conveyor 4, and the formed steel sheet S is placed on the formed steel sheet S. Board B
And push it out of the frame 2. FIG. 2 shows a state in which the formed formed steel sheet S is pushed out of the frame 2 in this manner. When the extrusion of the formed steel sheet S is completed in this way, the double-acting cylinder 53 of the extrusion device 5
Operate in the opposite direction to move the extruded frame 51 in the direction of the arrow to return it to its original state. At this time, since the formed steel sheet S is placed on the roller conveyor 4 via the plate piece B, it stops at that position, and only the frame 51 moves.

On the other hand, the raising / lowering arm 31 of the support device 3 has returned to the work start position in preparation for the next drop of the formed steel sheet S.

As described above, in the formed steel sheet stacking apparatus 1 of the present invention, the formed steel sheets S sent from the forming machine are sequentially stacked and discharged to the side. Therefore, there is no need to stop the forming machine or the like when the stacked formed steel sheets S are carried out, and the operation can be performed continuously. The stacked formed steel sheet S sent to the outside of the frame 2 may be moved to another place before the next formed steel sheet S is sent out using an appropriate means such as a crane or a lift.

In the above-described embodiment, the formed steel sheet S is dropped at a fixed small head by using the support device 3 having the lifting arm 31 to reduce the noise at the time of dropping and to reduce the displacement at the time of stacking. However, the stacked steel sheet stacking apparatus 1 of the present invention is configured so that the formed steel sheet S is perpendicular to the direction of extrusion from the forming machine so that the formed formed steel sheet S can be easily removed. The support device 3 is not necessarily required depending on the type of the formed steel sheet S and its falling state, as long as it is stacked on the roller conveyor 4 arranged in the direction.

If the length of the formed steel sheet extruded from the forming machine is short or its head is small, the support arm for temporarily supporting the formed steel sheet is omitted, and the extruded formed steel sheet is directly rolled. You may make it fall on a conveyor.

Further, in the embodiment, the extruder 5
Is used to automatically discharge the stacked formed steel sheets S from the stacking position.
Are stacked on the roller conveyor 4, so that manual discharge is also possible. When such manual discharge is performed, the extrusion device 5 may not be provided.
