DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for stacking formed steel sheets such as roofing materials.

[0002]

2. Description of the Related Art Corrugated formed steel sheets (roof decks) used as roofing materials for factories and warehouses are sequentially stacked at the exit of a forming machine. Moved to position. For this reason, a stacking device is conventionally installed at the outlet of the molding machine.

[0003] A conventional stacking apparatus has a side wall along one side of a formed steel sheet and an upper wall extending from the upper end of the side wall onto the formed steel sheet. The other side facing the side wall is open,
Further, a pair of opposing horizontal support rollers are attached to the ends of the side wall and the upper wall at regular intervals.

[0004] The formed steel sheet coming out of the forming machine is sent out onto the above-mentioned support roller, and when the feeding is completed, each support roller is rotated downward by the action of the air cylinder, and the formed steel sheet is dropped onto the lower bogie. Then, the support rollers are returned to a horizontal position, and thereafter, the formed steel sheets are sequentially stacked in the same manner. When the number of stacks reaches a certain number, move the bogie to the side,
After being pulled out to the side of the stacking device, a wire rope is hung on a bundle of formed steel plates and moved to an appropriate position by a crane.

[0005] Since the conventional stacking device is as described above, it is necessary to once pull out the formed steel sheet stacked on the carriage to the side of the stacking device, so that a certain space is required on the side of the device. was there. In addition, since the above-mentioned stacking device has a fixed length, there is a problem that it is difficult to adapt when the length of the formed steel plate changes.

Therefore, in order to eliminate the need for a space on the side of the forming steel sheet stacking device as in the prior art, and to provide flexibility that can freely cope with the length of the formed steel sheet, the applicant of the present invention has the following requirements. A patent application for a stacking device has been filed (Japanese Patent Application No. 5-306571 filed on December 7, 1993).

That is, in the stacking device, a plurality of supporting and guiding devices are installed between the forming machine and the stopper, and the respective supporting and guiding devices are opposed to each other on an independent base on both sides of the passage range of the formed steel sheet. It is composed of a pair of columns and a support arm provided on the column, and the support arm is positioned horizontally in the passing range to support the lower surface of the formed steel plate and releases the support of the lower surface of the formed steel plate. Therefore, it is possible to selectively take a state away from the passing range.

When such a stacking device for formed steel sheets is used, since the supporting devices are independent of each other, the number of installed steel plates can be easily increased or decreased according to the length of the formed steel plate, and high flexibility can be achieved. There is the convenience of having the property.

[0009]

The above stacking device is
A stopper is provided in front of the exit of the forming machine at a distance a little longer than the length of the formed steel sheet to abut against the tip of the formed steel sheet. Is the highest, and the height is gradually reduced.

[0010] When forming the formed steel sheet using this stacking device, if the tip of the formed steel sheet is dropped along the stopper, the tips are aligned, so that a plurality of formed steel sheets are stacked in order. It is convenient to transport or store those formed steel sheets to other places.

When the tip of the formed steel sheet is pushed back by the stopper and the rear end is dropped along the reference surface below the outlet of the forming machine, the rear ends are aligned, so that there is the same convenience as described above. .

However, in order to make the height of the support arms different from each other as described above, there is an inconvenience in that the height of each support arm must be individually adjusted. The height of the formed steel sheet becomes significantly shorter than the height of the outlet of the forming machine, and when the formed steel sheet is long, there is a problem that the height cannot be adjusted.

On the other hand, when the formed steel sheet is long,
When forming a molded steel plate at the roofing work site,
Formed steel sheets stacked on the base of each support and guide device are generally lifted by a crane and installed at an appropriate position on the roof, and are rarely transported or stored elsewhere as described above. Therefore, it is not always necessary to stack the formed steel sheets in an orderly manner.

Accordingly, an object of the present invention is to adjust the height difference as described above when forming such a long formed steel sheet, and each support arm supports the formed steel sheet at the same height. Thus, the above problem is solved.

However, if each support arm supports the formed steel plate at the same height, the tip of the formed steel plate is bent by its own weight and cannot pass over the support arm in the traveling direction. By sequentially raising the support arm and pushing back the deflection at the tip of the formed steel sheet,
An object of the present invention is to solve such a problem and to provide a stacking device suitable for a long formed steel sheet.

[0016]

A second state that has risen from the height of the state to the exit height of the forming machine, and a third state that has receded from the passing range of the formed steel sheet to release the support of the lower surface of the formed steel sheet. Made It is.

In addition, an auxiliary arm is provided between each of the columns and the passage of the formed steel plate of the pair of support arms of the support guide device, and the auxiliary arm is used to assist the lower surface of the formed steel plate. The support arm is inclined toward each of the columns.

[0018]

In the stacking apparatus having the above construction, a plurality of support guides are provided at a predetermined interval in front of the outlet of the molding machine, and the support arm of the first support guide closest to the outlet of the molding machine is connected to the molding machine. In this case, the first state is set lower in consideration of the lowering due to the bending of the tip of the formed steel sheet than the height of the outlet of the first steel sheet.

In the same manner as the first support arm, the support arms of the second and subsequent support guide devices are in the first state, which is positioned lower in consideration of the lowering due to the bending than the height of the outlet of the molding machine. I do.
