ES2599102B1 - Installation for training and filling of polygonal contour tubular containers - Google Patents

Abstract

Installation for the formation and filling of polygonal contour tubular containers, comprising the following units: # - a unit in which lower container trays (1), supplied by a conveyor are placed on mobile platforms (6); # - a unit for placing hollow prismatic tubular bodies (40) (2), which are coupled to each lower container tray (1); # - a filling unit (50) where the octagonal prismatic containers (3) that are openly open are filled to through its upper openings; # - a unit for placing upper trays (70) placed on each octagonal prismatic container (3) that is open and full, forming tubular containers with a polygonal contour (3) filled and covered. # The installation also includes translation means (35) by which the mobile platforms are transported from the palletizing unit (30) to the tray placement unit the upper ace (70) passing through the intermediate units.

However, in a preferred embodiment, it is contemplated that the tray-forming machines are at least two and the lower trays and upper trays manufactured are fed to the same conveyor device, which will then be in charge of distributing them between the lower tray supply conveyor and the upper tray supply conveyor.

In the above-described embodiments in which upper trays and identical lower trays are produced, said conveyor device includes a deflector device that deflects the lower trays and / or upper trays formed to the lower tray supply conveyor or to the supply conveyor. upper trays according to needs. This is possible because the upper trays and lower trays are identical to each other.

In another alternative embodiment to the above, it is proposed to integrate into the installation a tray-forming unit that includes at least one lower tray forming machine and one upper tray forming machine that respectively form lower container trays and upper container trays by bending and gluing of die-cut sheets of sheet material, and which also include two conveyor devices that respectively feed at least said lower tray supply conveyor and said upper tray supply conveyor with lower container trays and formed upper container trays . This embodiment allows the lower trays and the upper trays produced to be different, as they are produced in different forming machines that can have different configurations.

Additionally, and not limited to, it is contemplated that the installation comprises a second deflector device that deflects the lower trays and / or upper trays from the lower tray supply conveyor and / or from the upper tray supply conveyor to a conveyor auxiliary carrying the lower trays and / or upper trays to an accumulator where the lower trays and / or upper container trays from said auxiliary conveyor can be accumulated.

In this case it is also proposed that said accumulator comprises a mobile platform supply device that supplies mobile platforms on which the lower trays and / or upper trays from the auxiliary conveyor are stored.

Said accumulator may further comprise a device for stacking lower trays and / or upper trays, allowing said lower trays and / or upper trays to be stored in a stacked position.

It is also proposed that the lower trays and upper trays consist of an octagonal flat face delimited by a continuous protruding flap that surrounds said flat face, and that the prismatic tubular body has a perimeter approximately equal to the perimeter of the inner face of said perimeter flap . Said tubular body will be provided to be partially inserted in said lower tray and in said upper tray of the container with the perimeter flaps of the lower tray and the upper tray being superimposed on said prismatic tubular body, retaining it.

Preferably, the tubular polygonal contour containers, and therefore said lower container trays and upper trays, will be made of cardboard.

It has included another auxiliary conveyor, equipped with a stacking device and an accumulator, fed from the lower tray supply conveyor.

Detailed description of an embodiment example

Fig. 5 shows, for illustrative, non-limiting purposes, an example of the installation for the formation and filling of octagonal prismatic containers 3, proposed, which shares many of the characteristics with the embodiments shown in Figs. 1, 2, 3, 4 and 6.

The example of Fig. 5 is described in detail.

A tray forming unit 10 includes two lower and upper tray forming machines 11 which, from die-cut sheets 7 of sheet material, obtain said lower trays and upper trays by pushing a male against said sheet producing its insertion into a cavity by folding parts thereof, and that may include additional pushers and also glue applicators.

The lower trays 1 and upper container trays 4 formed by the two lower and upper tray forming machines 10 are supplied, by means of a conveyor device consisting of conveyor belts, both to the lower tray supply conveyor 20 and to the supply conveyor of upper trays 60, said two supply conveyors 20 and 60 being composed of conveyor belts.

Each of said forming machines can produce both lower tray and upper trays, since in this example said lower trays and said upper trays are identical, and can be supplied to the two supply conveyors 20 and 60 interchangeably. This is achieved by the fact that the conveyor device consists of two branches, each fed from one of the lower and upper tray forming machines 11, which converge allowing to supply in a single row the lower and upper trays 1 and 4 supplied interchangeably by a or other forming machine. A baffle allows to regulate the passage of the lower trays or upper trays produced by one or another forming machine 11.

Said single row of lower trays and upper trays is divided and by controlling a first deflector 13, it allows the lower trays and upper trays transported by the conveyor device to be diverted to the lower tray supply conveyor 20 or to the supply conveyor upper trays 60.

This configuration allows one or the other forming machine to feed either the conveyor supply of lower trays 20 or upper trays 60, also allowing production to be adjusted to the needs of the installation.

The lower tray supply conveyor 20 feeds the palletizing unit 30, and it is responsible for depositing the lower container trays 1 on a mobile platform 6 according to a predetermined precise arrangement. In this exemplary embodiment, two lower trays are pushed transversely by a transverse pusher, and two other lower trays are placed next to them, obtaining a matrix of four lower trays. Said matrix is then pushed laterally to be placed on a mobile platform 6.
