Description

Technical Field

[0001] The utility model relates to the field of automatic material stacking, in particular to a foam strip stacking device for a cylindrical foam strip barrel. Background Art

[0002] Elevator guide rails are elevator components consisting of steel rails and connecting plates. Existing guide rails can be divided into three types according to their cross-sectional shapes: T-shaped, L-shaped, and hollow. Hollow elevator guide rails are widely used because of their advantages such as light weight and material saving. Hollow elevator guide rails are generally filled with foam strips to make them soundproof, noise-reducing, and shock-absorbing. In order to realize the automation of foam strip filling, the foam strips must first be stacked together according to a rule. At present, the stacking of foam strips is all manual work. In this way, workers need to repeat the same mechanical movements all the time, which not only requires a lot of labor and low worker efficiency, but also the stacking quality cannot be guaranteed to meet uniform standards.
