Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for aligning and loading paper tubes on a carriage. 2. Description of the Related Art Paper tubes delivered to a papermaking company are sorted by size, placed on a trolley, and carried to a paper winding device. To place the paper tube on the trolley, support the shafts that fit in the opening at the end of the paper tube with a margin, corresponding to the pitch of the paper tube with respect to the paper tube aligned on the mounting table. The shaft row is fitted into the opening row of the paper core, and the paper core row is lifted together with the support shaft row, and is transferred onto a carriage. In the above case, since each paper tube is lifted by cantilever support, the posture of the paper tube being lifted is not stable.
When adjacent paper tubes collide with each other and are loaded on a cart, there is a problem that the next paper tube strongly hits the previously loaded paper tube and damages the paper tube. The present invention discloses a loading device that supports both ends of each paper core of a paper core row and can automatically load the bogie with the posture of the paper core stabilized. SUMMARY OF THE INVENTION The present invention relates to a paper core having a shaft core.
