Abstract

Machine for stacking objects, characterized by the fact that on the endless belt or chain of the bed of the machine, there is a bridge running through said belt or endless chain, leaving the bridge raised above it with the separation enough so that they can be stacked one on top of the other, two objects with a supporting base surface or, failing that, a support tray for one or several of said objects, existing at the base of the bridge a sliding carriage, at will, between the walls of the bridge, by means of a pneumatic piston of double effect, which movement of displacement of the car is carried out in the same direction and speed of advance as that of the belt or endless chain carrying the objects or trays to be stacked and existing in the external part of the birth of each sliding carriage of the bridge, hooks articulated by their point of birth, the free ends of which are bent at an appreciably straight angle and in the position of retention of an object or carrier tray of several, such hooks are in a vertical downward position and their angled end goes through the descending walls of the car, existing one on each side, which walls are provided with vertical notches that reach up to its lower edge, there being as many as hooks, the tips of which protrude through the internal walls of the cart, thus allowing those objects or trays to be collected below the edge of the two opposite sides thereof, once an ascending platform, operated by a pneumatic piston raises the object or tray that has remained immediately above the aforementioned platform, which in this phase is retracted and occurring when the tape or endless chain is stopped, with enough time for the alluded platform ascend, collect underneath the object or carrier tray of several of them, supported by the inta or endless chain, raise it to the height of the trolley of the bridge and that the hooks, pushed by the pneumatic piston, enter the trolley, are placed under the opposite edges of the object or carrier tray of several of them and to the descending the platform retains it or retains it in suspension, the platform being retracted, thus allowing the new advancement of the endless chain or belt and that when passing through the station where the bridge is with the sliding carriage, this car carrying the carrier object or tray previously collected, is set in motion, advance at the same speed and direction as the endless belt and when it is in the vertical of the object or lower tray the pneumatic piston that brings or separates the supporting hooks acts against them and it makes them go backwards with what their free ends come out, articulately, from the interior of the car and the object or tray that until that moment was supported by said hooks falls on the lower tray carrying the same belt or endless chain in motion, the set stacked to a collection station or to a second stacking station, or successive stacking stations, as appropriate, which or which is the same or equal than the previous one, but with the particularity that the bridge has a higher height so that the two or more objects or the two or more trays stacked in the previous station fit in the car, making all the movements as in the previous season and by the same means described.
