Abstract (en)
[origin: US6202912B1] A band product accumulation unit including a mechanism for controlling the running of a band along a longitudinal direction, a fixed frame, a wrap-around carriage which is moveable on a track between a return position of minimum accumulation length and an out position of maximum accumulation length, wherein movement towards the out position increases a length while movement towards the return position decreases the length, the band being adapted to pass over at least one return member mounted on the wrap-around carriage so as to form at least an out portion and at least a return portion and defined by at least two spaced levels, a plurality of intermediate supporting members arranged along the track, each comprising at least one separating arm extending horizontally on at least one intermediate level disposed between two running levels of the band, each separating arm being fixed to a shaft which is pivotal about a vertical axis with respect to the fixed frame, a mechanism for controling the pivoting of each separating arm between an open position which allows the wrap-around carriage to move to the return position and a closed position wherein each separating arm extends transverse to and between the two running levels of the band, and a control mechanism for controlling the pivoting of each separating arm between the closed position and the open position.
Abstract (fr)
L'invention a pour objet une installation d'accumulation d'un produit en bande (B) comprenant un chariot de bouclage (1) et des bras séparateurs (4) qui sont ouverts ou fermés par un dispositif suiveur (6) coopérant avec un dispositif à came (5) monté sur le chariot de bouclage (1). Conformément à l'invention, le dispositif suiveur (6) est décalé par rapport à l'axe (80) de pivotement du bras correspondant (4) et relié à celui-ci par un mécanisme articulé (7) ayant deux positions angulaires stables qui déterminent le maintien du bras (4), respectivement dans une position écartée (M1) ou dans une position engagée (M2), tant que le dispositif suiveur (61) n'est pas sollicité, par le passage dans un sens ou dans l'autre de la surface active (51) du dispositif à came (5). <IMAGE>
