ABSTRACT:
Device for stacking of articles of which the upper most article of the stack is maintained automatically at a certain level.
The device comprises a vertical container for the stack of articles, said container having an opening at the upper side around which an annular flange is arranged, on which a number of main tension springs is suspended, which support the body part of a carrier, whereas the supporting plane part of the carrier rests on the body part of the carrier by means of preferentially a single central helical compression spring, having a diameter approaching the main dimension of the carrier.
The strength of this helical compression spring is weaker than that of the body springs, so that at loading with a stack of articles, the supporting plane moves down resiliently faster, and also a greater part of the carrier is used for the stack of articles and thereby an increase of capacity is obtained, with stable support for the stack of articles.
