The above-mentioned transport device is generally used.

In this conventional roll base paper transporting device, after the remaining roll base paper transferred from the mill roll stand to the tray is transferred to the base paper carry-out section, a plurality of workers push it out to the ground by hand. Therefore, when the remaining roll base paper has a large diameter and a large weight, there is a drawback in that it is extremely heavy labor and takes time. For this reason, the corrugated board production line has become faster, and there is a device that can easily and quickly discharge the remaining roll base paper from the rails to the ground from the corrugated board manufacturing industry where orders such as paper quality and paper width are frequently changed due to low-lot production. It was strongly desired.

In order to meet the demands of the industry,
A device that pushes up one side of the bogie running on the rail with the lifting device, tilts the bogie with the lower ends of the wheels of the bogie supported by the rail as a fulcrum, and discharges the roll base paper on the base while rotating it to the base paper discharge part. Developed (Actual Kaihei 4-1)
(See Japanese Patent No. 12845).

However, when the roll base paper is discharged from the tray by inclining the carriage, a large load is applied to the shaft of the wheel supported by the rail when the roll base paper having a large weight is discharged from the tray. It was sometimes damaged.

It is vertically movable and swingably connected to
In addition, an elevating device for pushing up one side of the tray is installed in the rail corresponding to the base paper discharging section of the rail.

[0008]

After the roll base paper held on the mill roll stand is transferred to the pan on the rail, the pan is retracted to the base paper discharge section, and the lifting device is operated as shown by the chain line in FIG. When is pushed up, the pan tilts and the roll base paper on the pan rolls and is discharged to the ground. In this case, since the operation of the elevating device does not reach the traveling body, the traveling body is not derailed and the axle and the like are not damaged.

After the hoisting device is operated in reverse and the tray is returned to the rail as shown by the solid line in FIG. 4, it is advanced to the base paper carry-in section, and a new roll base paper waiting on one side is forklifted. Etc. are used to place on the pan, and the pan is advanced to the position of the mill roll stand to hold the roll base paper on the mill roll stand.

According to the present invention, since the hollow rail is used in which the upper surface is aligned with the ground surface and the guide groove is formed at the center of the upper surface over the entire length, the saucer travels on the rail.
