Stacker for plate members, method for stacking plate members, and stacked plate members

Abstract

A stacker (10) for plate members includes a platform (15) on which plate members (20) are to be stacked and at least one pair of guides (11, 13) disposed at both sides of the platform (15) relative to a transferring direction of the plate members. Each of the guides (11, 13) has a ridge (12a, 14a) spirally formed on a rotational axial portion (12, 14) and a groove (12b, 14b) formed along the ridge (12a, 14a). The aforementioned at least one pair of guides (11, 13) are rotated with opposite edges of the plate member (20) engaged with the grooves (12b, 14b) of the guides (11, 13), to thereby move the plate member (20) toward the platform (15).

AI Technical Summary

Problems solved by technology

[0007] In the former stacker that stacks panels by letting them fall naturally, there is such a problem that the impact at the time of falling may deform the inner fins because the inner fins are thin and thus easily deformed

Also, since the inner fins are thin and usually made of aluminum or an aluminum alloy, and are therefore very light, the drop rate is low, which in turn slows down the buildup rate

Also, since the inner fins are made with a wavy cross-section, it is difficult to determine the direction of their fall, which makes it difficult to place them neatly

[0008] On the other hand, in the latter stacker using cam stacking plates, since the inner fins are positioned one by one, the stacking rate is low.

In addition, since the inner fin is easily deformed due to its thin thickness, the cam causes deformation of the inner fin

[0009] Also, since the oil-free inner fins are difficult to slide over each other, it can be difficult to stack them neatly
