Machine for sorting and stacking containers with hinged walls

摘要

Machine for sorting and stacking stacks of containers of different heights and of individual containers with hinged walls, capable of forming stacks with a height suitable for palletizing, formed from a single feed line (A) consisting of one or more Conveyor belts, from a detection station (B), from at least one reject belt (X), from at least two stacking units (C1, C2, C3), which are provided at the exit of parking guides (4e) and downstream of the guides of a common discharge belt (E) , characterized in that the single feed line (A) serves the detection station (B), all stacking units (C1, C2, C3) and the reject belt (X) that for the transfer of the from the feed line (A) to the reject belt (X) or stacks or individual containers (2a) fed to the individual stacking units (C1, C2, C3) across the feed line (A), retaining strips (20b, 21b, 22b, 23b) act (20c, 21c, 22c, 23c) and then slides (20, 21, 22, 23) act (20a, 21a, 22a, 23a) and that the movement (2a) of the conveyor belt or belts of the infeed line (A) during the operations of the detection station (B), during the action of the retaining bars (20c, 21c, 22c, 23c) and during the action of the slide (20, 21, 22, 23) continues, whereas it continues for the time of holding and transferring a stack or a single container corresponding stacking unit is only blocked if the distance to the following stack or container, which is detected by the photoelectric barrier (2f) in the area of the detection station (B), is minimal.
