ES2065233A2 - Device for depalletising boxes and for stacking empty pallets - Google Patents

Abstract

The device for depalletising boxes is defined by a displaceable bridge 1 provided with lower rolling devices ("rulinas") 2 which run on guides 3 integral with parallel beams 4 in the shape of a U, which beams incorporate, at their ends, pinions joined in pairs via transverse shafts 6, chains 8 for entraining the pallets being coupled on said pinions and running over the flanges of the aforesaid U-beams 4. The bridge 1 has lower vertical guides 10 via which slide pieces 11 connected to levers 12, the latter in turn being fixed to the ends of a rocking shaft 13 coupled between the beams 4 at the same time as it rotates in both directions in order to displace the bridge 1. The latter includes a pair of depalletising arms 18 moved in a vertical direction on their own chains which rotate, coupled to two pinions 20. The empty-pallet stacker has parallel guides which extend until they are close to the ends of the beams 4 via which the empty pallets exit. These pallets are automatically placed on a platform which is pushed upwards until it is raised to a specific height, the empty pallets resting via their corners on fold-down seats.
