Procedure and apparatus for transferring flexible bags filled with an illiquid or liable product from a first container to a second container
Field of the Invention
The present invention concerns a method and an apparatus for transferring flexible bags filled with a liquid product or capable of flowing from a first container to a second container. Typically, the bags contain a flowing material, such as crushed fruit pulp, and are stored in a rigid container that facilitates handling and storage and protects the bag from breakage, tearing, weathering, and other circumstances that could damage the stored product, this container system being known as "bag in box".
State of the art
It is known in the state of the art the use of flexible bags for the storage and transport of flowing materials, typically used to contain food products or processes, such as fruit or vegetable pulp. The bags may have a mouth, or inlet opening that can be provided with a valve, plug, or be heat sealed, and an easy opening system can be provided to facilitate emptying.
When the bags exceed a certain size and weight they are difficult to handle, especially due to their flexible nature and filled with a flowing material. Usually the bags can weigh 200 kg or more.
In addition, the protection offered by the aforementioned bag is limited since said bag can be easily perforated or accidentally torn. In some cases, the bag may not offer enough protection against sunlight, which could degrade some foods. For all these reasons, these large-sized bags are typically stored in a rigid container that protects them and facilitates their handling and storage, for example allowing their stacking.
This product consisting of a bag stored inside a container is known in the sector as "bag in box".

Typically, the container intended to store the bag is a metal drum, as it offers optimal protection, allowing it to be stored outdoors, and the great durability of the drums allows them to be reused multiple times, or stored long periods of time in The weather.
However, the drums eventually oxidize, so it is occasionally required to transfer said bag from a drum that, for whatever reason, has stopped being suitable to another drum, performing said operation manually or with manually manipulated rigs, and with great difficulty and risk of bag breakage.
Another difficulty presented by the solution of storing the bags in drums is that the contained product has to be transported along with the drum from the bag filling plant to the plant where the product stored in the bags is consumed by emptying them. After consumption of the product, the bags can be discarded, but the drums must be stored and returned to the bag filling plant for reuse due to the high cost of the metal drums, which causes high logistic costs.
Alternatively it is known to store the bags in prismatic cardboard boxes preferably of octagonal section, known in the industry with the name of "octabin", "bin box", "bulk box" or "bulk container". The cardboard boxes are composed of example of two opposite octagonal trays, each obtained from the folding and joining of parts of a die-cut plate made of cardboard sheet, corrugated cardboard, plastic, corrugated plastic, or other similar semi-rigid material, the two opposite octagonal trays being connected by an octagonal prismatic tubular body made of an iron of the same material as the trays.
The advantages of using cardboard containers are that they are lighter and cheaper, they can be destroyed and recycled at the plant where the product stored in the bags is consumed, so a logistic is not required to return empty containers to the bag filling plant, and also the cardboard containers can be manufactured on-site at the moment, thus saving! the storage of empty containers which results in lower logistic costs. On the contrary, these cardboard containers cannot be stored outdoors, and have a lower resistance than metal drums, so they allow less stacking.
Automatic transfer of bags from metal drums to cardboard containers is unknown.

Exposition of the invention
According to a first aspect, the present invention provides a method for transferring flexible bags filled with a liquid product or capable of flowing from a first container to a second container, wherein the flexible bag has at one end a base that rests on a bottom of the first container and at another opposite end an opening element adjacent to an upper opening of the first container.
The procedure comprises the steps of:
- flip the first container to remove the flexible bag by gravity by first moving the flexible bag with the opening element in front;
- receive the flexible bag on a support;
- apply a second movement to the flexible bag with the base in front by means of a movement of the support and / or at least one other auxiliary support; and
- insert the flexible bag into the second container by means of the second movement,
whereby the flexible bag is arranged with the base resting on a bottom of the second container and the opening element adjacent to an upper opening of the second container.
Thus, the proposed procedure includes extracting a flexible bag from the inside of a first container by means of flipping the first container causing the extraction of the bag from the inside of said first container due to the effect of gravity by means of a first displacement. The extracted flexible bag is received by a support that holds it. Subsequently, a movement of the support, or of an auxiliary support, applies a second displacement to the flexible bag by which the flexible bag is inserted into a second container.
This method allows a transfer of a flexible bag filled with a liquid product or with a product capable of flowing from a first container to a second container in a safe way. This allows the container to be replaced if it is damaged, or it allows replacing a first container with features, with a second container with different characteristics than the first container.

To facilitate the sliding by gravity of the flexible bag 50 during its removal from the first container 1, the turning support 11 of the turning device 10 is connected to vibration means including, for example, a vibrating device 41, so that the vibration of the turning support 11 is transmitted to the first container 1 disposed thereon. This vibrating device 41 may include, for example, an eccentric rotating mass, a cam and follower mechanism, or a crank and connecting rod mechanism, and is actuated by vibrator drive means, such as for example an electric motor or a dynamic fluid actuator (not shown).
In order to avoid folds that can end in tearing of the flexible bag (50) during its extraction from the first container 1, the first conveyor 12 is associated with fastening and guiding means comprising, for example illustrated in Figs. 20 and 21, two pairs of clamps 42 installed on respective sliding carriages 43 along glues 44 parallel to the direction of movement of the conveyor belt of the first conveyor 12 and located on both sides thereof. The carriages 43 are moved along the glides 44 by carriage driving means, such as one or more electric motors or one or more dynamic fluid actuators (not shown), and the clamps are opened and closed by means of clamp drive, such as electric motors or dynamic fluid actuators (not shown).
Preferably, the clamps 42 are mounted on the carriages 43 by means of retractable devices (not shown) that remove the clamps 42 from the path of the flexible bag 50 when the flexible bag 50 is completely deposited on the first conveyor 12.
After turning the first container 1, and preferably after the flexible bag 50 has come into contact with the first conveyor 12, the clamps 42 grip portions of the flexible bag 50 adjacent to the opening element 52 and the carriages 44 are displaced along the glues 44 accompanying the first displacement of the flexible bag 50.
Optionally, the clamps 42 incorporate a force sensor (not shown) whereby the clamps 42 cease to hold or the carriage driving means cease to act when the force exerted by the clamps 42 as detected by the force sensor is brings, meets or exceeds a known tension that is capable of supporting the material of the flexible bag 50. This force sensor can be, for example, a device that in
function of the displacement of a spring of known elastic constant, opens the clamps 42 when the force exerted exceeds a predetermined value. In another embodiment, the force detector may include a dynamometer or a load cell.
With the apparatus of this fifth embodiment the procedure is analogous to that described above 5 in relation to the fourth embodiment, except that the change of position of the second conveyor 13 implies a rotation with respect to a vertical axis instead of a translation in one direction transverse to the direction of movement of the conveyor belt.
It will be understood that the vibration means and / or the fastening and guiding means are applicable to any of the possible embodiments of the apparatus of the present invention.
10 With the apparatus and method of any of the embodiments of the present invention, the flexible bag 50 is disposed in the second container 2 in the same position as it was in the first container 1, that is, with the base 51 resting on the bottom of the second container 2 and the opening element 52 adjacent to the upper opening of the second container 2.
