DESCRIPTION

INSTALLATION for forming and filling tubular containers of

Polygonal contour

Technique Field

The present invention concerns the field of installations, comprising several operating units, for the formation and filling of polygonal contour tubular containers located on mobile platforms, for the storage and transpose of bulk product, preferably liquid, fluid, viscous or granular product said tubular container being formed by a lower tray and an octagonal upper tray connected by a tubular body.

Said lower and upper trays, of the two ends of a polygonal contour tubular container, known in the sector as "bulk box, bin box or bulk container" and usable to contain, acting as an envelope, bags or flexible bags filled with a liquid, crushed or shredded product, for example pellets, or material of a very diverse nature in bulk, hermetically sealed and optionally pasteurized. In particular, these tubular containers with lower tray and upper tray are preferably used in the sector of fruit and vegetable packaging in aseptic bags (pure, cremogenated, diced, etc.).

State of the art

Machines for forming upper or lower boxes or trays are known, generally rectangular in shape, but octagonal boxes and trays are also known. Said boxes and trays are formed by bending and joining of die-cut plates, initially flat, made of laminate of a relatively rigid material, such as cardboard, corrugated cardboard, plastic, corrugated plastic, and the like.

The aforementioned octagonal boxes are also known, for example through documents DE 202004005667 U1, ES 2394186 T3 and ES 1057235 U which disclose respective lower trays or upper trays for octagonal shaped prismatic boxes formed from the folding and joining of parts of a die cut iron. The die-cut iron has an octagonal wall bounded by eight fold lines and eight side walls, each of which extends from one of the eight sides. The eight side walls comprise four side walls with alternating side flaps with four side walls with top flap. Each of the walls

Side with side flaps has two joining flaps that extend from the side edges thereof, and each of the side walls with top flap has a retention flap that extends from one edge of the same opposite to the corresponding fold line , the height of the retention flap being equivalent to the height of the wall.

According to the aforementioned documents DE202004005667 U1, ES2394186 T3 and ES1057235 U, the lower tray or upper tray is formed manually by folding the side walls to a position perpendicular to the lower tray wall, then folding the union flaps, then folding the retention flaps above the 10 binding flaps, and finally introducing tabs that protrude from the edges of the retention fins in corresponding openings formed in the octagonal wall in positions adjacent to the fold lines, so that the flaps of union they are trapped between the retention flaps and the corresponding side walls. However, a drawback of this construction is that the manual formation 15 of the lower trays or upper trays is relatively cumbersome and requires a lot of labor. Another drawback is that the need to provide the retention flaps with a height equivalent to the height of the wall implies a considerable extension of the die-cut plate that results in a high consumption of sheet material.

20 Automatic machines for forming lower trays or upper trays of prismatic boxes are also known from die-cut plates such as that described, for example, in the aforementioned document ES2394186 T3, or that sold by the Tecnobox or Reipal companies.

However, no document has been located that anticipates an installation for the assembly, filling and sealing of octagonal containers mounted on mobile platforms in an automated way, providing mobile platforms loaded with octagonal containers full of product and sealed, ready for transpose.

Brief description of the invention

The present invention concerns an installation for the formation and filling of tubular containers of polygonal contour.

It will be understood that a polygonal contour tubular container is a container formed by two parallel octagonal faces joined by eight laterally rectangular faces

connected, defining a hollow interior space, said two parallel faces being regular octagons, or irregular octagons. Said tubular container will be obtained by means of an octagonal lower tray provided with side walls, connected with an octagonal upper tray provided with side walls by means of a tubular body 5 partially confined between said lateral walls.

Preferably, the geometry of the polygonal contour tubular container proposed to be a rectangular orthohedron with four truncated corners, said truncations forming four rectangular faces.

The present invention proposes that said installation for formation and filling of

10 containers comprise the following units arranged in the following order:

• a palletizing unit in which one or more lower container trays, supplied by a lower tray supply conveyor, are placed on mobile platforms, supplied by a mobile platform supply device;

15 • a unit for placing bodies where a prismatic tubular body,

coming from a body supply device, it is coupled to each lower container tray placed on a mobile platform forming tubular containers of superiorly open polygonal contour;

• a filling unit where polygonal contour tubular containers

Top 20 open placed on mobile platforms are filled through

of its upper openings;

• an upper tray placement unit where an upper container tray, from an upper tray supply conveyor, is placed on each upper polygonal contour tubular container

25 open and full, forming full polygonal contour tubular containers and

covered tray; and

including the installation a means of translation by means of which the mobile platforms are transported from the palletizing unit to the upper tray placement unit passing through the intermediate units.

30 Thus, the proposed installation deposits one or several lower container trays on a mobile platform in the palletizing unit, then a prismatic tubular body is connected to said lower tray in the body positioning unit, thus providing the height container and from a top opening.

Subsequently the container is filled with a product, preferably a liquid, fluid, viscous or granular product, in the filling unit and then the upper tray placement unit proceeds to close the upper opening of the container by placing an upper tray of container in connection with the tubular body.

The units described above require a supply of lower trays, hollow tubular bodies and upper container trays, as well as a supply of mobile platforms. These supplies are provided respectively by a lower tray supply conveyor, a body supply device, an upper tray supply conveyor and a mobile platform supply device.

In addition, the installation includes means of translation that are responsible for moving the mobile platforms from one unit to the next, from the mobile platform supply device of the palletizing unit to the upper tray placement unit.

Additionally and with optional character it is proposed that, between the one unit of placement of bodies and the filling unit, a unit of placement of bags is integrated, intended to include inside each tubular container of polygonal contour, which is devoid of upper tray, an upper open bag of complementary size and shape with said interior of the polygonal contour tubular container, so that the filling unit produces the pouring of the product inside said bag. Said bag allows to improve the hygienic conditions of the container, an important aspect in the case of containing food products, and also allows the pouring of liquid, viscous or fluid products, preventing said products from wetting the container, or filtering through their joints.

After the filling unit, a bag sealing unit can be included, in charge of closing and sealing the bags after filling, before proceeding to place the upper tray of the container in the upper tray placement unit.

According to another embodiment, the installation integrates a container holding unit that ties the polygonal contour tubular containers arranged on a mobile platform by means of a tying device, individually wrapping each polygonal contour tubular container, wrapping the set of tubular polygonal contour containers arranged on the same mobile platform, or wrapping the assembly of mobile platform and tubular containers of polygonal contour, said holding unit being found in

5

any position subsequent to the body placement unit, intended to tie the containers before or after filling or placing the upper tray.

Ace! as said container holding unit wraps the containers totally or partially with a tying element, reinforcing the resistance of said containers, and / or ensuring that they are not accidentally or intentionally opened, and / or protecting them from water or moisture, and / or fixing its position with respect to the mobile platform to ensure safe transport, etc. Examples of usable tying elements are a plastic sheet, a shrink wrap, strapping, adhesive tape, etc.

Said container holding unit will preferably be located behind the upper tray placement unit, so that the polygonal contour tubular containers will be full and covered when arriving at said container holding unit, and the means of translation will be responsible for transport the mobile platforms from the upper tray placement unit to the container holding unit.

Other embodiments are also contemplated, such as for example that the container holding unit is positioned before the filling unit, so that the binding of the containers, even empty and without an upper tray, increases their strength and stability to produce a filling sure.

It is also expected that the binding of the containers will occur after filling and before the placement of the upper tray, thus ensuring the containers, but allowing easy access to the goods contained in the containers without the need to remove the ties to remove the upper tray

According to another preferred embodiment, the said means of translation transport the mobile platforms, on which said tubular containers of polygonal contour are placed, from the last unit of the installation to a delivery station where the mobile platforms are accessible by a pallet truck its extraction of the installation for training and filling of tubular containers. Said last unit of the installation may be the upper tray placement unit, or the container holding unit.

It is also contemplated that the proposed installation also includes a tray-forming unit that includes at least one lower tray forming machine, in charge or in charge of forming lower container trays by folding and gluing of die-cut sheets of sheet material, including said unit of formation of

Lower trays also drum a conveyor device that feeds at least said lower tray supply conveyor with formed lower container trays.

Thus, said tray forming unit includes one or several lower tray forming machines. Each of said machines produces, from die-cut sheets of sheet material, such as flat cardboard sheets, said lower container trays by automatically folding parts of said plates, and preferably joining them by adhesive, for obtaining of the lower container trays provided with an octagonal face surrounded by protruding flap 10, or side walls.

The aforementioned automatic forming machines can be, for example, those produced by the Techobox or Reipal companies at the date of this request.

Each lower container tray produced by the lower tray forming machines is transported by means of a conveyor to the lower tray supply conveyor, which is responsible for providing the said lower container trays produced to the palletizing unit.

In the event that the lower tray forming unit includes multiple lower tray forming machines, it is contemplated that the conveyor device picks up the lower trays produced in said tray forming machines and delivers them 20 to a single tray supply conveyor, by example by supplying in a single row the lower container trays formed by different forming machines arranged alternately.

According to another additional embodiment, the installation comprises a tray-forming unit that includes at least one upper tray forming machine that forms 25 upper container trays by folding and gluing of die-cut sheets of sheet material, and also includes a conveyor device that feeds at least said upper tray supply conveyor with formed upper container trays. All the characteristics of the upper tray forming unit, the upper tray forming machines and the upper container trays 30 formed are equivalent to those described in reference to the lower tray forming unit, to the tray forming machine. bottom trays and bottom container trays formed.

It is understood that the proposed invention also includes a tray forming unit that includes at least one lower tray forming machine and at least

an upper tray forming machine, which allows the lower and upper trays produced to be different from each other, adapted to their different needs. For example, the lower trays should have a greater structural resistance, since they will be subjected to greater efforts when loading the containers with 5 products, while the upper trays have lower resistant requirements, allowing them to be produced with less material or with a less resistant material. For example, it is contemplated that the side walls of the lower trays have a height greater than the side walls of the upper trays, thus allowing to save sheet material in the production of the upper trays. Also the thickness of the cardboard may be different, or a cardboard with more layers may be used for the production of the lower trays.

It also allows to include special features to the lower or upper trays, such as perforations provided in the upper trays.

According to another alternative embodiment, it is proposed that the installation comprises a unit of 15 tray formation, the lower trays and the upper trays being identical to each other. The aforementioned lower tray and upper tray forming unit includes at least one lower tray and upper tray forming machine that forms lower container trays and upper container trays interchangeably, by bending and gluing of die-cut sheets of sheet material, and which 20 also includes a conveyor device that feeds at least said lower tray supply conveyor and said upper tray supply conveyor with lower container trays and formed upper container trays. Being the lower trays and the upper trays identical to each other, the same forming machine can produce both parts of the containers 25 interchangeably, or they can be several forming machines, each being dedicated to manufacturing only or lower trays or upper trays, or producing all of them lower trays and upper trays interchangeably. In any case, the lower trays and upper trays produced would then be distributed to the lower tray supply conveyor and to the upper tray supply conveyor 30.

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

divide 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 baffle device 5 that deflects the lower trays and / or upper trays formed to the lower tray supply conveyor or to the supply conveyor. of upper trays according to the needs. This is possible because the upper trays and lower trays are identical to each other.

In another alternative embodiment to the previous ones, it is proposed to integrate into the installation a 10 tray forming unit that includes at least one lower tray forming machine and an 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 15 and said upper tray supply conveyor with lower container trays and with upper trays of container formed. 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.

20 Additionally, and with a non-limiting character, 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 towards a auxiliary conveyor that carries the lower trays and / or upper trays to an accumulator where the lower trays and / or 25 upper container trays from said auxiliary conveyor can be accumulated.

In such a 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 stacking device of lower trays and / or upper trays, allowing said lower trays and / or upper trays to be stored in stacked position.

It is also proposed that the lower trays and the upper trays consist of an octagonal flat face bounded 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 5 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.

Other features of the invention will appear in the following detailed description of an embodiment example.

Fig. 6 shows an embodiment like the one shown in Fig. 4, but in which the lower tray and upper tray forming unit integrates a lower tray forming machine and an upper tray forming machine, each in charge of feeding respectively the lower tray supply conveyor and the upper tray supply conveyor, and in which another auxiliary conveyor, equipped with a stacking device and an accumulator, fed from the lower tray supply conveyor, has also been included.

Detailed description of an embodiment example

Fig. 5 shows, with an illustrative non-limiting character, 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

5

said sheet producing its insertion in a cavity by folding parts thereof, and which 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 conveyor for supplying 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 thanks to 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 another training 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, allows 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 to regulate the production 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 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.

The mobile platform 6 is supplied by a mobile platform supply device 31 which can consist, for example, of a stack of mobile platforms 6, and said device can grip and cyclically lift the entire stack of mobile platforms 6 except the mobile platform lower, thus releasing it from the weight of the other mobile platforms, to

proceed to push it laterally to the position where the palletizing unit requires it.

Translation means 35 move the said mobile platform 6, loaded with a matrix of four lower trays 1, to the body placement unit 40, where 5 four tubular bodies 2 hollow prisms, supplied by a body supply device 41, they are fitted in the four lower container trays 1, leaving an open top opening. This operation can be performed manually or automatically, and the tubular bodies 2 supplied by the body supply device 41 will preferably be stored folded pianos, and therefore the placement operation will require a first operation of expansion of the tubular bodies 2 prior to Your placement

Next, the transfer means 35 introduce the mobile platform 6 into the filling unit 50, where a product to be stored is poured by gravity into each of the containers 3 through said upper opening, preferably with a 15 control of the amount poured to ensure that container 3 is full without overflowing.

The transfer means 35 then move the mobile platform 6 to the upper tray placement unit 70, which in turn is fed with upper trays 4 from the upper tray supply conveyor 60. In the present example the upper trays 4 of container are placed forming a matrix of 20 four upper trays 4 in the same way described in the case of the lower trays 1, and subsequently placed face down on the four containers 3 closing the upper openings of the four containers 3, by means of a positioning device of upper trays 71, the four upper trays 4 being fitted in the respective hollow tubular bodies 2. Said positioning device 25 of upper trays 71 consists of an arm provided for grasping the upper trays 4 and for carrying out the necessary displacement to reach the final position.

Then the translation means 35 move the mobile platform 6 loaded with the four containers 3 filled and covered up to the container holding unit 80, where a binding device 81 is responsible for sealing the containers, for example 30 by wrapping the assembly of mobile platform 6 and four containers 3 with a plastic sheet, thus preventing their accidental separation or opening.

Next, the transfer means 35 is responsible for carrying the said mobile platform 6 to a delivery station 90 where the mobile platform 6 with full and covered containers 3 is accessible by a pallet truck 91 for its extraction from the installation.

In the case of the installation described referring to Fig. 5, a second deflector is also included located at a point of the upper tray supply conveyor 60, which allows to derive part of the upper trays 4 transported towards an auxiliary conveyor 62, where a stacking unit 25 stacks the upper trays 4 and an accumulator 5 63 allows said stacks of upper trays to be deposited on a mobile platform 6 for

Your storage

This feature allows an overproduction of upper trays 4 to be accumulated to serve other facilities, or future operations of the current installation.
