Definitions

  • the invention relates to the technical sector of handling, more particularly the handling of flat shaped materials.
  • the packaging chain includes other items such as: packaging, labeling, and others ...
  • the empty trays are placed on the transfer belt manually.
  • the empty trays being nested one inside the other according to stacks of different heights, the operator grasps a tray in the stack and places it on the mat, this operation being repeated throughout the working time of the operation. It is understood that such a method is painful and permanently requires a person.
  • the rate is necessarily reduced, and above all, it cannot be regular and constant throughout the operator's intervention, which prohibits or greatly disrupts the automation of other stations.
  • Some conveyors are equipped with automatic tray dispensers, but these are an integral part of the whole machine and can therefore only be used for specific applications.
  • the assembly thus formed is very expensive, the dispenser being further limited in terms of capacity and type of trays to be used.
  • the trays must be placed manually in the dispenser.
  • Patent GB 979,689 teaches another solution for the automatic setting of trays, but which is limited to a single type of tray taking into account the complexity of the means of implementation. This is also the case of Patent FR 2,450,767 where the trays are of a particular type, with imprints for housing the products.
  • the invention has set itself the goal, in a simple, efficient and rational way of overcoming the various aforementioned drawbacks by developing a machine which solves the problems posed by being shaped to constitute a completely independent assembly in the packaging chain. by being able to adapt to any type of conveyor, and to receive all types of trays whatever their dimensions.
  • the invention solves on the one hand the problem of the unitary grip of the tray from a stack, in a safe and effective manner, taking into account the nature of the material constituting these trays and, on the other hand, the problem of automatic tray feeding of the machine.
  • the machine suitably includes mounted on a support frame, at least one store shaped and arranged with means to allow the positioning and maintaining in superposition of a plurality of trays above a means of transport and evacuation under which is mounted, in alignment with the store, at least one member capable of physically grasping a container and positioning it on said means of transport and evacuation; next to the store, is mounted a charger arranged to receive several stacks of trays arranged in juxtaposition while being equipped with means capable of ensuring, on the one hand, the temporary retention of said trays and, on the other hand, depending on the height of the stack of trays in the store, the automatic installation of a new stack in said store.
